My Relationship with my Parents

I truly value my relationship with my parents. The role of my parents and my siblings in my life can hardly ever be overstated. To begin with, I should state that my parents have always provided me with support. Their opinion has always played a significant role in my decision making process. Whenever I had a problematic situation over the course of my life I would necessarily talk to my parents about an issue that generated a seemingly irresolvable dilemma. I could go talk to my father about almost anything. When I was in high school and actually all my way through college my parents used to give my valuable advices as to what kind of men I should choose for relationships, what classes I should take and what cloths I should put on. They always taught me something. I cannot say that I necessarily followed their advice. The ultimate source that I always refer to when I have to make an important decision is my own brain. I believe that I am smart enough as well as experienced enough to make my own decisions. However, it is always important to consult my parents simply because they might give me a different perspective that I would never think of on my own. Even though their opinion might not be exactly what I am looking for at a particular point in my life, their contribution is extremely valuable. It is hard to explain but sometimes when I get in a really complex position and I feel that I know the answer to a question that torments me I go talk to my parents anyway. Most of the time I am totally positive that I will not take their advice and that my own decision will the one that I will take eventually but it is just important for me to have my parents hear my story and contribute to my decision. In other words there are times when I need someone to talk to. My parents and my siblings are the only people that I will select for that role.

My parents and siblings provide a great deal of moral support at times of trouble. However, the role of those people in my life is not confined to comforting me when I cannot find a way out of a complex situation. My relationship with my brother and sister is somewhat different. Of course my brother and sister support me a lot in almost any situation and I am sure that they are the people that I can count on in case I have a dilemma to deal with. However, there has always been tremendous competition among us in the family. It was always vital for me to excel my siblings in almost every aspect of life. Back when I was a high school student I felt like I needed to pick better grades in all the classes that we took together. When it was time for me to pick a university to apply to I always had to know what schools my brother and sister applied to so that I could apply to a better one. That ultimate desire to be the best in the family has always dominated my personality. At this point I cannot say for sure whether it is a good or bad thing. Sometimes I happened to excel in something and that brought me enormous satisfaction. Other times I would sustain a considerable failure and that would just devastate me completely. Nevertheless, now that I can take a look back at my entire life and consciously evaluation everything I ever did I can confidently state that I would not have accomplished most of the things that I have ever done in my life had I not have my siblings. They were the source of my energy and my drive that motivated and inspired me to persevere and keep going even when a situation was bleak and hopeless. My brother and sister are that people that I have to thank for almost everything that I have achieved over the course of my life. I did not realize that when I was younger. Now I can clearly see their role in my life.

Spyware, Viruses, Malware, Worms, Trojan Horses, and Adware: Symptoms, Solutions, and Prevention

Virus:

A Virus or Computer Virus is a self-replicating program or piece of script or code that make copies of itself and then either attaches itself to an existing file on the infected system or store copies of itself on the system with innocuous sounding names like ‘repair tool’.

The virus is limited to spread itself only by either being transmitted or sent by an unwitting user or carried on a portable storage medium from one system to another. However, if a virus gets embedded somewhere on a network drive then anyone who opens or clicks on the infected document or file can end up getting infected as well.

Spyware:

Spyware is software that gathers information about a users Internet habits, browsing patterns, email passwords, usernames and even credit card information, in essence, ‘spying’ on the hapless user. This type of software usually gets installed without the knowledge of the user and can transmit the collected data to a third party over the Internet secretly as well.

Malware:

Malware can refer to any number of malicious forms of software or code that has been intentionally designed to perform one or more of the following malicious acts:

> Infiltrate a users computer system without their consent.

> Gather sensitive personal information such as credit card numbers, social security numbers, birth dates, or system passwords.

> Create back doors or remote entry points to allow hackers access to the system.

> The destruction of critical data and/or corruption of system files.

Malware is a general term and is commonly used to include, Viruses, Worms, Spyware, Trojan Horses, and some forms of Adware. The actual intention of malware can vary but by definition it is any software that is destructive by nature. Because the term Malware is so broad it is hard to cite one specific source for the most infections.

Worm:

A Worm or Computer Worm is a self-replicating piece of computer code that uses a computer network to spread copies of itself to the other nodes on the network. Unlike the Virus a Worm can accomplish this without any intervention or help from the user. Also unlike a Computer Virus the Worm does not have to attach itself to an existing computer program or file.

Many times a Worm will also be used to carry a ‘payload’. The ‘payload’ is code that is designed to perform some specific function. In some cases the payload allows the Worm to send documents through the email accounts of the infected system attaching itself and its payload to the email as an attachment. When the unsuspecting recipient of the email opens the attachment the process starts again.

Trojan Horse:

A Trojan or Trojan Horse Virus is a program that usually gets downloaded installed and executed on a computer system which then appears to be performing some useful function but is unknowingly allowing unauthorized access to the user’s computer system at the same time.

Hackers use Trojans to gain access to a user’s computer remotely and then perform any number of malicious activities. These nefarious activities can include but certainly are not limited to:

> Data Theft.

> Keystroke Logging.

> Downloading or Uploading Files.

> Viewing the Victims Screen.

> Crashing the Users System.

Adware:

Adware is advertiser supported software that displays, plays or downloads advertisements either onto the computer desktop or into the computers web browser as a condition of the software installation. Most Adware is free to use as long as you don’t mind annoying pop-up windows appearing at random intervals advertising some product or another. I have seen some Adware that opened a new window about every 1 to 2 minutes, making it nearly impossible to use the system at all until the software had to be removed.

Additionally, Adware will almost always be collecting data about your Internet habits and browsing behavior to tailor ads specifically to best match the data recovered. In that respect it is actually very similar to many types of Spyware. In most cases Adware is simply a way to place advertisements in the face of the user although it’s a fine line before you could also classify it as Spyware.

With Adware however, in some cases you may actually be given a chance to review and choose whether or not to accept the terms and conditions associated with the software before installing it.

IT WOULD BE ADVISABLE TO READ THESE TERMS VERY CAREFULLY BEFORE CHOOSING TO ACCEPT.

Symptoms of Infection:

> Very sluggish computer performance.

> Random system lockups or crashes.

> Browser redirection – you are taken to websites you were not searching for while browsing the Internet.

> Excessive number of popup windows appearing at random while surfing the Internet.

> You are informed that your system has ‘hundreds’ of active infections and you are redirected to a website that insists you pay for and download their specific software package to remove the infections.

Solution:

There are many good anti-virus / anti-spyware products on the market designed to detect and remove these types of infections. McAfee and Kapersky are good but AVG and Avast! have similar products and offer a free downloadable version. Be sure to complete a ‘Full’ system scan and quarantine and remove all active infections. Configure your anti-virus software to perform ‘active’ scanning or real-time system monitoring.

Prevention:

> Do not install software you have downloaded from the Internet unless it has come from a known, reliable source.

> Use caution if using file sharing platforms such as LimeWire or torrent sites to download files.

> Do not open any email attachments from unknown sources.

> Use a good anti-virus/anti-spyware application and scan your system at least weekly. Be sure your anti-virus software is totally up to date with the latest virus definitions.

> For Windows users: Be sure to visit the Microsoft update site and download all the latest Microsoft security patches.

Starter Clicks But Engine Does Not Turn Over – Tech in Trunk?

If the car’s starter clicks and the engine does not turn over, this could be caused by several things. The most common cause of clicking when the car is being started is a low battery. Most people would assume that the starter is bad if it only clicks, but low-voltage can cause the starter to make this sound.

The battery is the heart of the starting and electrical system. If the battery has been drained or has a weak cell, this can cause the starter to only click. Many times the battery could just been drained due to a door left slightly open, making the dome light stay on. Other times a vanity light or a phone charger could be left on. During my time as a master auto technician, I’ve had a trustworthy co-worker close me up in the trunk so I could make sure the trunk light went off when the trunk was closed!

In order to test the battery it must have a good charge. If the battery is not charged completely the tester will indicate that it needs to be charged before testing can proceed. The first step when checking the starter and electrical system is to make sure the battery is in good condition. Most parts stores will check batteries for free. Once it’s determined the battery is good the rest of the system can then be checked. Loose or corroded connections can also cause a clicking and for the car not to start.

Starter

The starter solenoid on many Ford vehicle’s is on the inner fender well, on most other vehicles the starter solenoid will be mounted on the starter. The clicking that is heard many times is the solenoid. But low-voltage either from a drained battery, bad battery or poor connections can cause this. Most of the time if the vehicle can be jump-started the starter is okay. This would also indicate that the connections to the starter are good.

Alternator

Once the vehicle is running the alternator output can be checked. If the alternator is not charging the battery, it will be drained during the process of starting the car and driving. When the alternator is checked, the voltage and amperage output can be measured. Also the diode pattern will be checked to make sure the alternator won’t drain the battery when the engine is turned off. In the past do-it-yourselfers could disconnect the battery while the vehicle is running to check the alternator, if the car kept running the alternator was good. Doing this on computerized vehicles can be harmful. If the battery is disconnected while a computerized vehicle is running the alternator output can increase sharply allowing excess voltage to spike the computer.

Battery

When purchasing a replacement battery the cold cranking amps required for the vehicle should be checked. It’s best to purchase a battery with more cold cranking amps than the minimum required. Also when purchasing a battery you should consider if you want maintenance free or not. If the battery is hard to access or has a cover then a maintenance free battery is preferred. For instance on some Chrysler Sebrings and Chevrolet Corvettes the battery is located behind an inner fender and on a Chevrolet SSR. the battery is located underneath the bed where the spare tire would normally go. If installing the battery yourself be sure to notice which side is positive and negative in case you were sold the incorrect battery.

Terminals

The terminals should be free of corrosion and should tighten up well. Sometimes especially on import vehicles the battery terminals will be very thin and can have hairline cracks causing a poor connection. Avoid forcing the battery terminals on by tapping them. The battery casing can be damaged causing a leak, if the battery acid seeps out it can cause fast corrosion. If the battery terminal bolts will not tighten, then replacing the terminals is recommended. When the connections are tight you should not be able to twist them by hand.

5 Simple Steps to Having a Healthy Pregnancy

If you’ve decided to have a baby, the most important thing is that you care a lot, so that both you and the baby are healthy in the future. Girls who receive proper care and take the right decisions are highly likely to have healthy babies.

Prenatal Care

If you discover you are pregnant, see a doctor as soon as possible to begin receiving prenatal care (care during pregnancy). The sooner you begin receiving medical care, the better the chances that both you and your baby are healthy in the future.

If you can not afford to visit a doctor or pay for the consultation in a clinic for prenatal care, social service organizations exist that can help. Ask your parents, school counselor or another trusted adult to help you find resources in your community.

During the first consultation, the doctor will make a lot of questions, such as date of your last period. In this way, you can calculate how long have you been pregnant and what date you expect your baby.

Doctors estimate the duration of pregnancy in weeks. The due date is estimated, but the majority of babies born between 38 and 42 weeks after the first day of last menstrual period of women, or between 36 and 38 weeks after conception (when the sperm fertilizes the egg). Only a small percentage of women giving birth at the estimated delivery date.

The pregnancy is divided into three phases, or quarters. The first quarter runs from conception to end of week 13. The second is from week 14 to 26. The third, from week 27 until the end of pregnancy.

The doctor will examine you and perform a pelvic exam. The doctor will also order blood tests, urine tests and tests to check for sexually transmitted diseases (STD by its acronym in English), including an HIV test, an increasingly common condition in adolescents. (Because some STDs can cause serious health problems in newborns, it is important to get appropriate treatment to protect the baby.)

The doctor will explain what are the physical and emotional changes that are likely to experience during pregnancy. We also learn to recognize the symptoms of possible problems (complications) during pregnancy. This is essential, because teenagers are at greater risk of crossing certain complications such as anemia or hypertension, and give birth before the expected date (premature labor).

Your doctor will want to start taking prenatal vitamins containing folic acid, calcium and iron away. Your doctor may prescribe vitamins or can recommend a brand you can buy without a prescription. These minerals and vitamins help to ensure the good health of baby and mother, and avoid certain birth defects.

Ideally, you should visit your doctor once a month during the first 28 weeks of pregnancy. Then you should visit every 2 weeks until week 36 and weekly thereafter until delivery. If you have a disease like diabetes, which requires careful monitoring during pregnancy, it is likely that your doctor wants to see you more often.

During consultations, your doctor will monitor your weight, blood pressure and urine, in addition to measuring your belly to go record the baby’s growth. When the baby’s heartbeat can be heard with a special device, the doctor will listen to every time you visit. It is likely that your doctor will also indicate other tests during pregnancy, such as an ultrasound to make sure the baby is in perfect condition.

Also part of prenatal care to attend classes where women who are expecting a baby learning how to have a healthy pregnancy and delivery, as well as what are the basic care for the newborn. It is likely that these classes are conducted in hospitals, medical centers, schools and universities in your area.

If adults can be difficult to talk to your doctor about your own body, this is even more difficult for adolescents. The role of your doctor is to help you enjoy a healthy pregnancy and have a healthy baby… and it is likely that there is nothing that a pregnant woman has not told. So do not be afraid to ask about everything you need to know.

Always be honest when your doctor will ask questions, even if they are embarrassing. Many of the issues that your doctor wants you to cover could affect the health of your baby. Think of your doctor as someone who is not only a resource but also a friend you can trust to talk about what is happening to you.

What changes can you expect in your body

Pregnancy creates many physical changes. Here are some of the most common:

Growth of breasts

The increase in breast size is one of the first signs of pregnancy and the breasts may continue to grow throughout pregnancy. It is possible to increase several sizes of support during the course of pregnancy.

Skin changes

Do not be surprised if people’s comments that your skin looks “glowing” when you’re pregnant: pregnancy produces an increased blood volume, which can make your cheeks are a little more pink than usual. In addition, hormonal changes increase the secretion of the sebaceous glands, so that your skin may look brighter. For the same reason, acne is also common during pregnancy.

Among other changes that pregnancy hormones generated in the skin are yellowish or brownish spots that appear on the face, which are called melasma, and a dark stripe running from the navel to the pubis, which known as linea nigra.

Also, moles or freckles that you had before pregnancy may increase in size or become darker. Even the areola, the area around the nipple becomes darker. Stretch marks may also occur (thin lines of pink or purple) in the abdomen, breasts or thighs.

Except for the darkening of the areola, which is usually permanent, these skin changes will disappear after delivery.

Mood swings

It is very common to experience mood swings during pregnancy. Some girls may suffer from depression during pregnancy or after childbirth. If you have symptoms of depression such as sadness, changes in sleep patterns, desires to hurt yourself or negative feelings about yourself or your life, ask your doctor for advice about starting your treatment.

Pregnancy Discomforts

Pregnancy can cause some unpleasant side effects. Among such disorders, include the following:

  • nausea and vomiting, especially during the first months of pregnancy;
  • leg swelling;
  • varicose veins in the legs and the area around the vaginal opening;
  • hemorrhoids;
  • heartburn and constipation;
  • back pain;
  • fatigue and
  • sleeping problems.

If you suffer from one or more of these side effects, remember that you are not alone. Ask your doctor for advice on how to handle these common problems.

If you are pregnant and have bleeding or pain, contact your doctor right away, even if you decided to terminate your pregnancy.

What you should avoid

If you smoke, drink alcohol or use drugs during pregnancy, both you and your baby are at risk for serious problems.

Alcohol

At present, doctors believe it is not advisable to drink a drop of alcohol during pregnancy. If you drink alcoholic beverages can damage the developing fetus and the baby is at risk for birth defects and mental problems.

Smoke

Smoking during pregnancy carries some of the following risks: the birth of a dead fetus (when a baby dies inside the womb), low birth weight (which increases the possibility that the baby has health problems), infants infants (babies born before 37 weeks) syndrome and sudden infant death (SIDS for its acronym in English). SIDS is the sudden death for no apparent reason, a baby under one year.

Drugs

Illegal drugs such as cocaine or marijuana during pregnancy may cause abortions, premature births and other health problems. In addition, babies can be born with an addiction to certain drugs.

If you have trouble quitting smoking, drinking alcohol or using drugs, ask your doctor to help you. Consult your doctor before taking any medication during pregnancy. This includes medicines sold over the counter, prepared herbal supplements and vitamins.

Unsafe Sex

Talk to your doctor about sex during pregnancy. If your doctor allows you to have sex during pregnancy, you should use a condom to avoid contracting a sexually transmitted disease (STD in English). Because some STDs can cause blindness, pneumonia or meningitis in the newborn, it is important for you to protect yourself and protect the baby.

How to take care during pregnancy

Feeding

Many young people are concerned by the appearance of your body and fear of weight gain during pregnancy. But this is not the time to cut calories or go on a diet because you are feeding two people. Both you and your baby need certain nutrients for the baby to grow properly. If you eat a variety of healthy foods, drink enough water and you reduce the junk food, high fat, help to both you and the baby are healthy and growing.

Doctors generally recommend adding about 300 calories a day to the diet, so as to provide the baby with adequate nutrition growth. According to the weight you had before becoming pregnant, you should gain between 11 and 15 kilos (25 to 35 pounds) during pregnancy, mostly during the last 6 months. Your doctor will advise you about this depending on your particular situation.

Eat more fiber from -25 to 30 grams daily, and drinking enough water can help prevent common problems such as constipation. Fruits and vegetables and whole grain breads, cereals or whole wheat muffins are good sources of fiber.

It is necessary that you avoid some foods and beverages during pregnancy, such as:

  • some types of fish such as swordfish, canned tuna and other fish that may have a high content of mercury (your doctor can help you decide which fish to eat);
  • foods containing raw eggs, such as mousse or salad type “Caesar”;
  • raw meat, fish or just cooked;
  • processed meats such as sausages or cold cuts;
  • Unpasteurized soft cheeses such as feta, brie, blue or goat, and
  • milk, unpasteurized juice or cider.

It is also desirable to limit the consumption of artificial sweeteners and caffeine and artificial sweeteners.

Exercise

Exercising during pregnancy is good for your health when you have no complications with the pregnancy and choose appropriate activities. Doctors generally recommend low-impact activities such as walking, swimming and yoga. In general, you should avoid contact sports and high impact aerobic activities that pose a higher risk of injury. It is also not recommended to do a job that involves heavy lifting for women during pregnancy. Talk to your doctor if you have questions about what kind of exercises are safe for you and your baby.

Sleep

It is important to get plenty of rest during pregnancy. During the first months of pregnancy, trying to acquire the habit of sleeping on your side. As pregnancy progresses, lying on your side, knees bent, will be the most comfortable position. It will facilitate the functioning of the heart, since the baby’s weight will not exert any pressure on the vein that carries blood from the feet and legs back to the heart.

Some doctors specifically recommend that pregnant girls should sleep on his left side. Because some of the major blood vessels are in the right side of the abdomen, lying on the left side helps keep the uterus puts pressure on them. Ask your doctor what your recommendation. In most cases, the trick is to lie on either side, to reduce pressure on the back.

Throughout the pregnancy, but particularly in the later stages, it is likely that you wake up frequently at night to go to the bathroom. While it is important to drink plenty of water during pregnancy, try to drink more during the day instead of night. Go to the bathroom before bed. As the pregnancy progresses, you might be hard to find a comfortable position in bed. You can try placing pillows around and under the stomach, back or legs to feel more comfortable.

Stress can also affect sleep. Perhaps you’re concerned about the health of the baby, birth, or how it will play this new role of mother. All these feelings are normal, but can produce insomnia. Talk to your doctor if you have trouble sleeping during pregnancy.

Emotional Health

It is common for pregnant adolescents experience a variety of emotions such as fear, anger, guilt, confusion and sadness. Maybe you take some time to adjust to the fact that you are having a baby. It means a huge change and it is natural for pregnant teens wonder if they are ready for the responsibilities involved in becoming mothers.

The feelings of a young often depend on how much support received by the baby’s father, his family (and family of the baby’s father) and his friends. The situation of each youth is different. Depending on your situation, you may need to seek more support for people who are not part of your family. It is important to talk with people who can support you, guide you and help you share and sort out your feelings. Your school counselor or nurse can guide you to find the resources offered to help your community.

In some cases, teenage pregnancies and spontaneous abortions have lost the baby. This can be very sad and difficult to overcome for some, but to others it causes a feeling of relief. It is important to talk about these feelings and receive support from friends and family, if this is not possible, go to counselors or teachers.

The school and the future

Some girls plan to raise her baby by themselves. Sometimes grandparents or other family members help them. Some young people choose to deliver her baby for adoption. These difficult decisions involve a great deal of courage and concern for the baby.

Young women who have completed high school will have greater chances of getting a good job and enjoy a more successful life. As far as possible, you should finish high school now instead of trying to go back to school later. Ask your school counselor or a trusted adult that you provide information about what programs and classes offered in the community for pregnant teens.

Some communities have support groups especially devoted to teen parents. In some schools, no childcare. Perhaps a member of your family or a friend can take the baby while you’re at school.

You can learn more about what happens when you mother if you read books, attend classes or consultations reliable websites on parenting. Your pediatrician, your parents, your family members and other adults can guide you when you’re pregnant and when you become a mother.

Bloodborne Pathogens – Preventing Disease Transmission

Imagine receiving a call that an employee has been injured from a fall down a flight of steps at your facility. The caller tells you that 911 has been called and some of your fellow employees are tending to the victim. As a supervisor, you decide to respond to the scene.

You arrive just as firefighters and paramedics take over caring for the victim. These rescuers do their job well – the victim is stabilized, wrapped up for transport to the hospital and gently placed on the stretcher.

As you watch, you can’t help but notice that the firefighters and paramedics are wearing medical gloves and goggles. As EMS (emergency medical services) personnel leave the area, you approach the employees who helped to thank them for their efforts. Almost immediately you become aware of a very frightening sight – both of the rescuers have fairly large spots of blood on their clothing and, even more upsetting, both are using paper towels to wipe the blood off of their hands. It is obvious that these employees did nothing to protect themselves from disease transmission and both have been contaminated with the victim’s blood.

Wearing PPE (personal protective equipment) is an important part of professional rescuers’ equipment. They know that protecting themselves from bloodborne pathogens is, in some ways, just as important as caring for the victim. But what about your people – do they know the risks associated with not wearing protective equipment?

If your company provides first aid kits for employee use or if your employees are required to respond to a medical emergency, they should have access to protective equipment and receive training on bloodborne pathogens.

ASSESS YOUR OPERATION’S RISK FOR EXPOSURE – I was recently asked to evaluate exposure risks for an association of tow truck operators, body shop technicians and auto mechanics. These people lacked training on bloodborne pathogens.

Tow truck operators wear thick, leather work gloves and routinely pick up bloodstained windshields or wrap contaminated airbags around steering columns. Body shop technicians pull contaminated seats from wrecked vehicles and then sit on them during their breaks or at lunchtime. Mechanics have a tendency to cut their knuckles or foreheads while repairing vehicles. They also share tools with fellow employees – tools that are contaminated with blood from their last injury.

I know you’re not in the automobile repair business. The examples above are intended to get you thinking about your own operation’s risks of exposure to potentially dangerous body fluids. Do you have a first responder team or people assigned to respond to an emergency? Are first aid kits available to employees? Do employees share equipment or tools that could become contaminated? Who is responsible for cleaning up body fluids after an accident or injury?

Without proper communication policies and training in preventing disease transmission, your employees could find themselves exposed to the same dangers paramedics and firefighters face while coming to their aid.

So what can you do to reduce the risk of exposure? Let’s start with defining bloodborne pathogens and the impact that exposure to them can have on employees and employers.

CONTAMINATION PREVENTION GUIDELINES – Bloodborne pathogens are pathogenic microorganisms that are transmitted via human blood and cause disease in humans. They include – but are not limited to – hepatitis B and human immunodeficiency virus (HIV).

I know for many people (myself included) words like microorganisms, immunodeficiency and pathogens bring back thoughts of high school and health classes – the last places in the world most of us want to revisit. So before we go any further, let me put it in my terms: There’s a lot of junk out there that can make us very sick, or even kill us if we become contaminated.

We need to constantly be on guard and be very careful so that we don’t become contaminated. I’ve been teaching CPR and first aid training for over 25 years, and I’m often asked if I would do rescue breathing without a barrier on someone I do not know. I respond without hesitation: If I found someone unresponsive and not breathing, I would immediately call for help and begin chest compressions on the victim, but there is no way I would do mouth-to-mouth on the individual without a breathing barrier.

Emergency responders know the risks associated with coming in contact with bloodborne pathogens, and they know how to protect themselves. Unfortunately, far too many people in the workplace or good Samaritans on the street do little, if anything, to take the necessary precautions. Too often they realize they’ve been exposed to body fluids after the emergency, when it’s too late to do anything about it.

EMPLOYEES – Here are a few simple rules to follow when faced with the possibility of exposure to bloodborne pathogens, or any body fluids for that matter. This information is presented as guidelines for both employees and employers. The American Heart Association calls it “Making a PACT, Know How to Act.”

PROTECT – Protect yourself from blood or blood-containing materials. This includes wearing protective equipment such as gloves and goggles and using a breathing barrier if you are performing CPR. Consider your options if you find yourself with no protective equipment.

ACT – If you find you have come into contact with another person’s blood or other body fluids, act quickly and safely. Wash the area immediately with hot, soapy water for up to a minute before rinsing. If your eyes have been contaminated, flush them with clean water for up to five minutes. If a flushing agent is not available at the scene, have someone get water for you. Firefighters or paramedics can assist you if they are still at the scene.

CLEAN – After an emergency, especially in the shop area or office, clean any areas contaminated with blood or body fluids. Wear protective equipment. Clean the area with a solution of one part Clorox and eight parts water. Completely flush the area and let the solution stand for at least three minutes. Be careful when wiping up the area, especially if you are dealing with broken glass or wood or metal splinters. Put all soiled items, including soiled cleaning materials, in a plastic bag and take it to the dumpster as soon as you are finished. If there is an injection device (such as a needle) involved, try to give it to the medics or firefighters before they leave; otherwise, get it in the dumpster and use extreme caution while doing so.

TELL – Report the incident immediately to your supervisor or human resources department. Ask for a dated copy of the report (even if it is only handwritten).

EMPLOYERS’ RESPONSIBILITIES – Employers have a responsibility to protect their employees from exposure to bloodborne pathogens. Here are the specifics of this responsibility.

PERSONAL PROTECTIVE EQUIPMENT – Any employee at risk of being exposed to bloodborne pathogens must be provided with the protective equipment necessary to keep them safe from exposure. This equipment includes gloves, goggles and, if required, breathing masks or barriers for CPR.

EDUCATION – Not all professions require bloodborne pathogen education and prevention training.

A call to OSHA (Occupational Safety & Health Administration) may or may not give you the answer you are looking for. It appears as though OSHA looks at a number of factors when determining whether an employer does or does not have to comply. For example, if you offer voluntary CPR/first aid training to your employees, they may not be required to take bloodborne pathogen training. If you have designated first aid responders within your organization, you probably fall under the training requirements.

Many of you know your employees’ occupational exposure risk. If you have personnel who are routinely or even occasionally exposed to blood or body fluids in the execution of their duties, you may want to consider offering protective equipment and training to these employees.

ENGINEERING CONTROLS – Engineering controls help to protect employees from bloodborne pathogen contamination and prevent the spread of pathogens in the workplace. Here’s an example of engineering controls: An employee using his leather work gloves realizes he has come in contact with body fluids and the gloves are contaminated. Two controls should be in place to protect the employee. First, knowing his exposure risk, the employer should have a spare set of gloves on hand so that the operator can complete his job. Second, the company should have a procedure for disposing of or cleaning the soiled gloves.

WORK PRACTICES – Setting standard practices for preventing disease transmission is a very important part of an employer’s responsibility in protecting employees.

In the case of the body shop previously mentioned, good work practices would include establishing a policy requiring workers to wrap plastic around seats pulled from a wrecked vehicle and prohibiting them from sitting on the seats, even with the plastic cover in place.

Providing employees with their own toolboxes is another good practice. If they share tools, have a policy in place for cleaning and decontaminating tools, especially after an accident or injury. Moreover, make sure employees know the importance of disposing of or cleaning contaminated personal protective equipment.

Finally, offer a course in bloodborne pathogen training. It is an excellent way to communicate the importance of preventing disease transmission and protecting your company from a huge liability/workers compensation claim.

HAVE A WRITTEN POLICY AND REPORTING PROCEDURES IN PLACE – As I previously mentioned, implement policies related to bloodborne pathogens at your operation. Start small, then expand on the policies as new issues surface. Communicate with your people. Make sure they know the reporting procedures and the importance of reporting any possible contamination.

OSHA has templates for creating your own company bloodborne pathogens policy and/or procedure. Simply download the forms, fill in the blanks with your company name, etc., print them out and you’re good to go. Additional information can be obtained by calling your regional OSHA office.

TRAINING, POLICIES ARE WORTHWHILE INVESTMENTS – I am a business of one, but if I did have employees, I can assure you – they would be trained on bloodborne pathogen risks and contamination prevention, and my company would have a policy in place. It’s the right thing to do for a business, its employees and the employer. And just imagine how good it would feel to know that your operation is in compliance should OSHA officials decide to visit.

Invest an hour for setting up your program, distribute the information to your employees and arrange for a 30-minute bloodborne pathogen education and prevention class. The investment is small, but the dividends to you and your employees will be huge.

Activity Diagrams – Advantages, Disadvantages and Applications of Use

Activity diagrams describe the actual work flow behavior of a system in Information Technology. These diagrams are very similar to state Diagrams because activities are the actual state of doing something. These diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. Also, these diagrams can show activities that are conditional or parallel.

When to Use: Activity Diagrams

Activity diagrams should be used in alignment with other modeling techniques like interaction diagrams and State diagrams. The main reason behind using these diagrams is to model the work flow behind the system being designed. these Diagrams are also useful for analyzing a use case by describing what actions need to take place and when they should occur, describing a complicated sequential algorithm and modeling applications with parallel processes.

Activity diagrams’ advantages:

  • UML modeling language included that these diagrams are normally easily comprehensible for both analysts and stakeholders.
  • In UML for the IT Business Analyst, “The activity diagram is the one most useful to the IT BA for depicting work flow [because] it is simple to understand-both for BAs and end-users.”
  • Since they are among the most user-friendly diagrams available, they are generally regarded as an essential tool in an analyst’s repertoire.
  • Additionally, as stated above, activity diagrams allow an analyst to display multiple conditions and actors within a work flow through the use of swimlanes. Swimlanes, however, are optional as a single condition or actor is normally displayed without them.

Activity diagrams’ disadvantages:

UML modeling language include that these diagrams have the potential to become overly complex because their user-friendly nature may lend itself to an all-inclusive description. In other words, since it is so simple to display the information related to the project, why not include all of it? When an analyst has a large project, creating a single, overly complex diagram can be a temptation.

However, as one author notes, “if you are using activity diagrams to define the structure of a work flow, you should not attempt to explore several levels of activity graphs down to their most ‘atomic’ level”. Instead, an analyst should try to present a new diagram for each work flow, or if more applicable, to use swimlanes to present different actors within the same work flow.

Another aspect of these diagrams is that they may not be used in lieu of a state diagram or sequence diagram because “activity diagrams do not give detail about how objects behave or how objects collaborate.” This is not a disadvantage per se, but it is important for an analyst to keep in mind when applying diagrams to their work.

In conclusion, activity diagrams are fairly easy to get the hang of, and will be useful for most projects because they plainly and moderately clearly demonstrate how things work.” Unlike many diagramming techniques, these diagrams also enable the depiction of multiple choices and actors within a work flow, and they are easy for even non-technical users to follow

Applications of activity diagram:

This diagram has been extended to specify flows among steps that transmit physical matter (e.g., gasoline) or energy (e.g., torque, pressure).

  • Additional changes allow the diagram to better support continuous behaviors and continuous data flows.
  • The UML 2 specification significantly prolonged the features and scale of activity diagrams beyond their earlier classification as a special case of state diagrams.
  • Today, activity diagrams can be thought of as flow charts for the 21st century, and UML modelers use activity diagrams to describe it.
  • Also, these diagrams are useful in following methods:
  • Business Rules
  • Functions that occur in parallel
  • Complex chain of multiple use cases
  • Software flows and logic control configurations
  • Procedures with judgment points and alternate flows
  • Single use cases

Everything You Need to Know About Investing

To become successful with your money, you have to make your money work for you. You sell your labor which in return makes you money. By making each individual dollar work for you, this in return makes you wealthy over time. There are a plethora of investing opportunities out there. The key is to figure out which one is the right one for your financial situation.

Stocks
The most popular of all investing opportunities, are stocks. Stocks are probably the main thing you think of when you hear of investing. When you buy a stock, you buy partial ownership of a company. Stocks range anywhere from $2, to $12,000, which can appeal to a large variety of people. To be successful when trading stocks, you have to buy low and sell high. Of course this isn’t easy, considering the market is always fluctuating. You need to watch the history of the company, know the PE Ratio, the day range, the 52 week range, etc. Knowing this information can help you predict if the stock will go up or down. You can make a lot of money investing in stocks, which means you can also lose a lot of money. You want to keep in mind that most investments in stocks are long term investments. It is very risky investing, but if you do the proper research of the history of the company, you can get a very good return.

Stock Investing Tips

1.) Have the Right Expectations
When you are investing in stocks, you want to make sure you aren’t expecting to become Warren Buffet over night. It just wont happen. You want to make sure you do the proper amount of research, and make sure you know the history of the market as well as the company you are investing in. When investing in stocks, the return is around 10%-13%. You don’t want to make hasty decisions and buy and sell a lot just because you aren’t making the money you expected. Make sure you know how long you are keeping an investment, and then make a commitment. This will help you focus on the principles.

2.) Don’t Listen to the Media
Don’t get caught up in what everyone is talking about and what is being said around you. It will take your decision from being based on research and history, to just “hear-say”. This will hurt your investments immensely. Most of the hype and other things that are being said are just the daily fluctuation of the market.

3.) Stay Focused
You want to make sure you are putting all your effort and focus into your investments. Once you buy a stock, you own part of a company. Make sure you treat it the way it is and make sure you do the proper research of all aspects of what you’re investing in. Doing your research can change your investment of making a profit of $15,000, to losing $15,000. In the end, it’s always worth it to do the extra work.

Mutual Funds
When you invest in Mutual Funds, you are pooling your money with a number of other investors. You then pay someone to professionally manage and choose each individual security for you. There are a variety of different mutual funds you can choose to invest in, which range to fit your investment strategy.
3 Types of Mutual Funds
1.) Open-Ended
2.) Unit Investment Trust
3.) Close-Ended

Mutual Fund Investing Tips

1.) Look at the Fees
Always look at the fees involved when investing in Mutual Funds. When you pay more for something, this usually means that you are going to be getting a better product or service, right? Yes! Makes sure you find the best deal, but make sure you are investing the right amount of money in the right places. It can change the course of the whole investment in the long run.

2.) Research the History
One thing you can do to prepare an investment is to check out the history of the Mutual Fund. Just like anything, the history shows how well it has performed, and can be a good indicator. This can directly tell you if it will be a good investment whether it be long term or short term. Another thing you want to look at, is the asset of the fund. If it’s doing good, and there is a community of people investing in it, it can tell you if its a smart idea to invest yourself. Always check the history of any investment before you decide to purchase.

3.) Look at the Contract
You never know what is all involved until you take a detailed look at the prospectus provided by the fund. You want to make sure you don’t just know bits and pieces of what’s involved, but everything there is to know, and then some. Make sure you know all the fees involved with buying and selling funds, and if there are international fees required. Knowing this can help you determine if the company is a solid company where you can make money, or if you are getting into something you will regret in the future.

Bank Investments
Bank accounts are one of the simplest form of investment. Most banks give you a very small percentage for opening a bank account and giving them your money. This percentage barely beats the rise of inflation, so unless you are keeping hundreds of thousands of dollars in the bank, you won’t be creating any wealth from this form of investment. Another way to invest in your bank is a CD, or Certificate of Deposit. A CD if very similar to a bank account, but they are usually for a fixed amount of time. They can be monthly, every six months, a year, etc. the CD is then held until its maturity date, and paid back with interest. A Certificate of Deposit usually earns more money than an account at which you can withdrawal the money at any time, like a bank account.

Alternative Investments
Apart from the basic investments, there are other special securities. These investments include gold/silver, real estate, etc. These investments are speculative and can be very high profit, however; you need to have the knowledge.

1.) Gold & Silver
The first thing you want to do before you invest in gold or silver, is to look at the market and decide if now is the best time to invest in precious metals. You can also talk to a professional and decide when the best time to buy and sell would be. You want to make sure you are familiar with the variety of ways to invest in silver. You can invest in silver mining companies, silver ETF’s, silver futures, silver bullion, and also silver coins. You want to make sure the Exchange Traded Funds (ETF) are backed by physical gold and silver. Another thing to remember, is to not just own a paper owning, but the actual precious metal as well.

EDGE: A Stepping-stone Toward 3G Technologies in Pakistan

ABSTRACT

The business of wireless data is expected to grow in the region of 100-200 % per annum and the mobile communication industry agrees that wireless data services will form the foundation for future business. The enormous success of short messaging in many countries proves that people accept the benefits of non-voice services.

Enhanced Data Rate for Global Evolution (EDGE) is a technology that gives Global Systems for Mobile Communications (GSM) the capacity to handle services for the third generation of mobile telephony. It provides three times the data capacity of General packet Radio Service (GPRS). Using EDGE, operators can handle three times more subscribers than GPRS; triple their data rate per subscriber, or add extra capacity to their voice communications.

This article provides an overview of EDGE technology. In particular, starting from the introduction of this 2.5G technology I describe the core technical aspects and distinct features. I will provide a comparison with GPRS for data services and then a survey of the current state of this technology in Pakistan. I have also covered some benefits for operators and customers.

1. Introduction

The importance of wireless data and multimedia services both for business and end customers are increasing on an unparalleled scale. Enhanced Data Rates for GSM Evolution (EDGE) is a new radio interface solution and is based on an enhanced modulation. EDGE offers GSM network operators an evolution path to mobile data and multimedia services with a three fold increase of data throughput in the existing GSM spectrum. EDGE therefore provides an alternative for operators who do not have a Universal Mobile Telecommunication System (UMTS) license. Moreover it also represents a complement to UMTS for operators intending to first deploy UMTS only in densely populated areas, but who can also use EDGE to provide wide area coverage of future oriented 3G services. In the US market operators have chosen EDGE as the 3G solutions. [8].

We are presently experiencing the Wireless Application Protocol (WAP) as well as the higher   transmission  speeds of High Speed Circuit Switched Data (HSCSD), joined by the convenience of “always on-line” direct Internet connections with GPRS. [1]

EDGE, new radios interface technology with enhanced modulation, increases the HSCSD and GPRS data rates by up to three fold. EDGE modulation is going to increase the data throughput provided by the packet switched service even over 400 kbps per carrier. Similarly, the data rates of circuit switched data can be increased, or existing data rates can be achieved using fewer timeslots, saving capacity. Accordingly, these higher speed data services are referred to as EGPRS (Enhanced GPRS) and ECSD (Enhanced Circuit Switched Data).

EDGE, is a major improvement in GSM phase 2+. As a modification to existing GSM networks, EDGE does not require new network elements. [1]

In the US, for instance, EDGE is part of the IS-136 High Speed concept, which is one of the third generation Radio  Transmission  Technology (RTT) proposals from TR.45. EDGE is eventually going to be standardized which makes possible to achieve a global mobile radio system with many services characteristic to third generation systems.

2. Overview

The increased bit rates of EDGE put requirements on the GSM/GPRS network architecture. Figure. 1 illustrates the GSM/GPRS architecture, the shaded parts of which are discussed in this section. Other nodes and interfaces are not affected at all by EDGE introduction. An apparent bottleneck is the A-bis interface, which today supports up to 16 kb/s per traffic channel. With EDGE, the bit rate per traffic channel will approach 64 kb/s, which makes allocation of multiple A-bis slots to one traffic channel necessary. Alternative asynchronous transfer mode (ATM) or IP-based solutions to this problem can also be discusses.

One important fact is, however, that the 16 kb/s limit will be exceeded already by the introduction of two coding schemes (CS3 and CS4) in GPRS, which have a maximal bit rate per traffic channel of 22.8 kb/s. Consequently, the A-bis limitation problem is being solved outside the EDGE standardization, and it is therefore a GPRS related, not EDGE-related, modification. For GPRS-based packet data services, other nodes and interfaces are already capable of handling higher bit rates, and are thus not affected. For circuit-switched services, the A interface can handle 64 kb/s per user, which is not exceeded by EDGE circuit-switched bearers. [9]

2.1. Impact on GSM Network Planning

An important prerequisite, which to a large extent will determine the success of EDGE in GSM, is that a network operator be able to introduce EDGE gradually. For initial deployment, EDGE-capable transceivers will supplement standard GSM/GPRS transceivers in a subset of the existing cells where EDGE coverage is desired. Hence, an integrated mix of GSM, GPRS, and EDGE users will coexist in the same frequency band. To minimize effort and cost for the network operator, radio network planning (including cell planning, frequency setting of power and other cell parameters) must not require extensive modification.

2.1.1. Coverage Planning

One characteristic of non-transparent radio link protocols that include automatic repeat request (ARQ), is that low radio link quality only results in a lower bit rate for the user. Hence, low SIR for a user does not result in a dropped call, as for speech, but in a temporary decrease of user bit rate. For transparent bearers, which typically offer a constant bit rate, link quality control must be extended to incorporate resource allocation, in the sense that the number of dynamically allocated time slots fits the bit rate and bit error rate (BER) retirements. Transparent bearers, will thus be available in the entire GSM cell, but require fewer time slots in the center of the cell (where 8-PSK coding schemes can be used).

2.1.2. Frequency Planning

Most mature GSM networks of today have an average frequency reuse factor of around 9 (meaning that available frequencies are divided into nine frequency groups). However, there is also a trend toward tighter reuse factors. With the use of frequency hopping, multiple reuse patterns (MRP), and discontinuous  transmission  (DTX), reuse factors as low as 3 become feasible. EDGE supports a variety of reuse patterns. In fact, by its use of link quality control, EDGE can be introduced in an arbitrary frequency plan, and benefit from high SIR closer to the base stations. EDGE can be introduced in an existing GSM frequency plan, and that it also supports future high-capacity solutions based on tighter frequency reuse.

2.1.3. Radio Network Planning

An important prerequisite (and to a large extent, one that will determine the success of Edge) is that network operators should be able to introduce Edge gradually. The initial deployment of Edge-capable transceivers will supplement standard GSM transceivers in a subset of cells where Edge coverage is desired. An integrated mixture of circuit-switched, GPRS and Edge users will thus coexist in the same frequency band. To minimize operator efforts and costs, Edge-related implementation must not require extensive modification of the radio network plan (including cell planning, frequency planning, the setting of power levels and other cell parameters).

2.1.4. Channel Management

After Edge has been introduced, a cell will typically include two types of transceiver: standard GSM transceivers and Edge transceivers. Each physical channel (time slot) in the cell can be viewed as being one of at least four channel types:

1. GSM speech and GSM circuit-switched data (CSD);

2. GPRS packet data;

3. Circuit-switched data, enhanced circuits witched data (ECSD), and GSM speech;

4. Edge packet data (EGPRS), which allows a mix of GPRS and EGPRS users simultaneously.

While standard GSM transceivers only support channel types 1 and 2, Edge transceivers support all four channel types. Physical channels are dynamically defined according to terminal capabilities and needs in the cell. For example, if several speech users are active, the number of type-1 channels is increased, at the expense of GPRS and Edge channels. Obviously, channel management must be automated, to avoid the splitting of channels into static groups. Otherwise, trunking efficiency would diminish.

3. Interleaving

To increase the performance of the higher coding schemes in EGPRS (MCS7 to MCS9) even at low C/I, the interleaving procedure has been changed within the EGPRS standard. When frequency hopping is used, the radio environment is changing on a per-burst level. Because a radio block is interleaved and transmitted over four bursts for GPRS, each burst may experience a completely different interference environment. [7]

If just one of the four bursts is not properly received, the entire radio block will not be properly decoded and will have to be retransmitted. In the case of CS4 for GPRS, hardly any error protection is used at all. With EGPRS, the standard handles the higher coding scheme differently than GPRS to combat this problem. MCS7, MCS8 and MCS9 actually transmit two radio blocks over the four bursts, and the interleaving occurs over two bursts instead of four. This reduces the number of bursts that must be retransmitted should errors occur. The likelihood of receiving two consecutive error free bursts is higher than receiving four consecutive error free bursts. This means that the higher coding schemes

for EDGE have a better robustness with regard to frequency hopping.

4. EDGE & GPRS

EDGE, or the Enhanced Data Rate for Global Evolution, is the new mantra in the Global Internet Connectivity scene. EDGE is the new name for GSM 384. The technology was named GSM 384 because of the fact that it provided Data  Transmission  at a rate of 384 Kbps. It consists of the 8 pattern time slot, and the speed could be achieved when all the 8 time slots were used. The idea behind EDGE is to obtain even higher data rates on the current 200 KHz GSM carrier, by changing the type of the modulation used.

Now, this is the most striking feature. EDGE, as being once a GSM technology, works on the existing GSM or the TDMA carriers, and enables them to many of the 3G services. Although EDGE will have a little technical impact, since its fully based on GSM or the TDMA carriers, but it might just get an EDGE over the up coming technologies, and of course, the GPRS. With EDGE, the operators and service providers can offer more wireless data application, including wireless multimedia, e-mail (Web Based), Web Infotainment, and above all, the technology of Video Conferencing.

Now all these technologies that were named earlier, were the clauses of the IMT-UMTS 3G Package. But, with EDGE, we can get all these 3G services on our existing GSM phones, which might just prove to be a boon to the user.

The current scenario clearly states that EDGE will definitely score higher than GPRS. The former allows its users to increase the data speed and throughput capacity, to around 3-4 times higher than GPRS.

Secondly, it allows the existing GSM or the TDMA carriers to give the sophisticated 3G services. And with 1600 Million subscribers of GSM in over 170 countries, offer the full Global Roaming, anywhere between India to Japan and to San Francisco. Based on an 8 PSK modulation, it allows higher bit rate across the air Interface. There is one symbol for every 3 bits. Thus, EDGE Rate is equal to 3x GPRS Rate.

5. Future Evolution Towards WCDMA

The next evolutionary step for the GSM/EDGE cellular system includes enhancements of service provisioning for the packet-switched domain with the service provisioning in UMTS/UTRAN (UMTS terrestrial radio access network). GERAN will provide improved support for all quality of service (QoS) classes defined for UMTS: interactive, background, streaming and conversational. By doing so, a new range of applications, including IP multimedia applications, will be adequately supported. This part of the GSM/EDGE evolution focuses on support for the conversational and streaming service classes, because adequate support for interactive and background services already exists. Additionally, parallel simultaneous bearers will support multimedia applications with different QoS characteristics towards the same MS, such as multiple media streams handled through IMS domain. A driver for such evolution on the packet-switched side is the paradigm shift within the telecommunications world from circuit to packet-switched communications.

Both the core network defined for GPRS and the current GSM/EDGE radio access network require modifications to support enhanced packet services. The GPRS/EGPRS networks can quickly and cost effectively evolve with market needs, and align with services provided by WCDMA networks. The current evolution of GSM/EDGE, which covers all of the above aspects, is being standardized in 3GPP TSG GERAN. [4]

6. EDGE in Pakistan

Pakistan has the sixth largest population in the world – approximately 150 million. There are currently four mobile operators in the country. Mobile penetration at the end of 2003 was just 2.3% with a subscriber base of 3.4 million, while fixed line penetration was approximately 2.4%. Many geographic areas in Pakistan are without telephone coverage. To accompany recent positive economic development in Pakistan and the inherently low mobile penetration, high growth within the mobile segment is expected. At the moment the people in Pakistan are more concern with the text-enabled facility like SMS. Although the introduction of GPRS gave a new concept and new boost in Cellular network but still, people are not that much concern using Internet by their terminal. Few think that it still more costly and few believe that GPRS didn’t develop the interest for using Internet if we compared it by computer.

In April 2004 Norwegian mobile telecom operator, Telenor, bid for and ultimately won a license to operate a cellular network in Pakistan. The license covers the operation of Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology for the network. [14]

Telenor Pakistan has signed two deals with mobile infrastructure contractors for different areas of the network:

Nokia have signed a three-year deal to build and operate a GSM / GPRS / EDGE network to cover the central and Northern Punjab region (phase one), centered around Lahore.

Siemens have signed a deal to build a GSM / GPRS / EDGE network to cover the southern areas of Pakistan, centered around Islamabad.

Further enhancements in data capability over the core GPRS / GSM network will be provided in both networks with the installation of Enhanced Data for Global (GSM) Evolution technology. This component of the two systems will be installed after the initial roll-outs and will allow the subscribers to have the use of advanced mobile services such as downloading video and music clips, full multimedia messaging, high-speed color Internet access and email on the move.

Nortel Networks will upgrade Ufone’s existing wireless systems and supply new GSM/GPRS core network and radio access equipment, including Mobile Switching Center, Home Location Register (HLR) and advanced Base Transceiver Stations (BTS).

A key component of the Ufone expansion will be Nortel Networks BTS 12000, designed to deliver additional capacity within a GSM/GPRS network while positioning operators to drive lower costs and to offer advanced wireless services based on third generation (3G) EDGE (Enhanced Data for GSM Evolution) technology. The expansion will also include Nortel Networks Passport Packet Voice Gateway (PVG) for migration of TDM voice trunking to a packet-based infrastructure.

7. Benefits

As highlighted previously the need to reduce business risk and make the best use of existing resources is of paramount importance within today’s business environment.

7.1. Financial

GSM based networks have become the standard within the cellular landscape. As EDGE is a GSM based technology and provides an enhancement for GPRS at a little additional cost it is considered the best way in which to capitalize on existing resources. [1]

7.1.1. Radio Access Network

In most cases GPRS enabled base stations and BSC’s can be simply upgraded to EDGE by way of relatively low-cost software and hardware upgrades, which will pro-long the life cycle of the deployed RAN elements.

7.1.2. Core Network

For GPRS enhancement, there is very little modification to be completed within a GPRS enabled core network, thus enhancing the sunk core network investment.

7.1.3. Antenna Sites

There is no requirement for additional antenna sites when deploying EDGE. Assuming high quality linear amplifiers with high RF output power are used within the BTS, the coverage pattern will be the same as the existing GPRS deployment, so protecting existing site investment.

7.1.4. Spectrum Utilization

EDGE triples the GPRS data capacity whilst using the existing GSM spectrum and offers up to three times the GPRS data rate to the end user. EDGE is spectrally the most efficient radio technology for data applications requiring up to 100Kb/s throughput (compared to CDMA and WCDMA), and only WCDMA is spectrally better for higher throughputs.

7.1.5. Applications

GPRS enabled applications and services will generally not require any additional investment to become EDGE compatible. This is also valid for known WCDMA applications.

Although the financial benefits of EDGE can be apportioned to individual network elements as outlined above, one of the main business drivers is that EDGE forms an essential part of the overall GSM evolution towards a seamless multi-radio GSM/ GPRS/EDGE/WCDMA network. As mentioned previously GSM is the main standard for cellular communications worldwide and the business benefits of deploying an industry standard technology can be seen in nearly every aspect of a network deployment, from end-user devices, to applications to hardware.

7.2. For Operator

Operators can also experiences the advantages of EDGE in following ways.

7.2.1. Migration to wireless multimedia services

The operator can increase data revenues by offering attractive new types applications to end-users.

7.2.2. Improved customer satisfaction

Increased data capacity and higher data throughput will decrease response times for all data services, thus keeping end users satisfied and connected.

7.2.3. Early deployment of 3G type applications

EDGE networks are expected to emerge in year 2001, when mature markets are likely to start demanding multimedia applications.

7.2.4. Quick network implementation

EDGE will not require new network elements and EDGE capability can be introduced gradually to the network.

7.3. For User

7.3.1. Improved quality of service

Increased data capacity and higher data throughput will eventually satisfy the customers’ need for QoS.

7.3.2. Personal multimedia services

Attractive new types of applications and terminals will become available.

7.3.3. Potentially lower price per bit

Lower cost of data capacity for high-speed data applications gives the operator flexibility in pricing.

8. Conclusion

While the tug of war between access technologies – CDMA vs. UMTS vs. GSM — continues to be debated globally, EDGE provides an ideal solution for GSM carriers to add data capacity using limited spectrum. Keeping in view the fact that GSM supports more subscribers today than any other access technology (roughly 65 to 70% of the global subscriber market), and that GSM/GPRS operators are scrambling to add capacity to support user growth and launch next generation data services, the increased capacity and throughput offered by EDGE becomes very compelling. And, in a market where wireless carriers must squeeze the most out of capital outlays–past and future, it is no real surprise that we are going to see a renewed wave of interest in EDGE from our GSM customers.

Today the position of EDGE as a technology evolution of GSM is clear. Initially promoted as an alternative to WCDMA and generally a niche technology, EDGE is now regarded as a key enabler for GSM/EDGE and WCDMA operators alike. Being able to drive business value from existing GSM infrastructure and spectrum is one of the main advantages, and along-with the ability of EDGE to reduce CAPEX, time-to-market and time-to-revenue, with regards the delivery of global high-speed data services, EDGE is a must technology.

The cellular companies working in Pakistan did not have the license for the EDGE. Now as the introduction of some new companies like Telenor and WARID, it is possible that in near future Pakistan will also be able to use this facility. Then GPRS can become a real important factor in cellular network, as the people in Pakistan will use the Internet not only for downloading ring tones but also can enjoy the streaming videos by their cell phone and so many other facilities.

Ring Worm

Ringworm, also termed tinea corporis, is an infectious skin disease caused by mold-like fungi called Dermatophytes. This disease usually transmits through direct contact with ringworm-infected animals or with humans by sharing combs, clothing or by touching infected areas. Despite its name, there are no worms involved at any phase of the ringworm process. It used to be believed that a worm caused or was a symptom of ringworm, but now people know better. However, the name stuck.

The common symptoms for ringworms are itching, burning, dryness, or circular flaky rashes on the skin. Though, in the case of animals, the primary symptom is temporary hair loss in affected areas, itching or scratchiness in a specific body part.

A primary cause of ringworm is direct contact with infected animals or humans.

Ringworm is common among pets especially dogs and cats, who carry this disease from contaminated soil, kennels or from rodent burrows.

Ringworm thrives in moist conditions and commonly affects the scalp, toes, feet, thighs and genital area. Prevention requires that these areas be kept dry and clean to avoid infection, and pets should have regular veterinary checkups.

Ringworm is easily curable and there are several treatments available. At the first sign, see your doctor who can prescribe mediation to treat and cure ringworm within 2-3 weeks. Ringworm may not show up right away upon the time of contraction. In other words, it can exist as a contagious disease for a time before it can be detected. So do not blame others if their ringworm shows up before yours; you may have been the carrier in the first place!

Is Out-Of-State Real Estate Investing Right for You?

Have you made up your mind to start investing in real estate, but you’re torn in deciding where to invest?

Are you thinking about making a local investment, but wondering if an out-of-state investment might be better?

This is one of the first of many choices you’ll have to make when you decide to invest in real estate: the simple question of where you should invest your hard-earned dollars. While there are definite benefits to investing in your area, there are also some potentially profit-limiting downsides.

That’s not to say investing in outside areas doesn’t have its own pros and cons. Let’s take a look at both and see why out-of-state real estate investing might be a profitable option you have not yet explored.

Investing Locally

This is the most obvious choice for many real estate investors, but is it really right for you?

If you choose to buy a property local to you, you’ll rest easier about your investment since you know the market. First, you know your competition. You might know the names of professionals you can trust and you’ll have an intimate understanding of what the cost of living is for that area and how to make things more affordable.

Second, if you like to be hands-on, it will be much easier for you since you’re right there. If you want to see the property, it’s just a short drive away. If you want to talk to the property manager face-to-face, you just put it on your calendar for the end of the day.

Drawbacks to Local Investments

On the other hand, investing solely local can narrow your options. Not every market has the inventory of good investment opportunities that you can avail yourself of if you invest out-of-state. The local inventory of available properties may or may not be big enough or well-suited for investment opportunities.

You also run into the problem of whether your local market is the one you want. The recession made a huge impact on housing markets throughout the country and some areas have recovered at different paces than others. You might find yourself out-priced in your current market, but even if you aren’t, you might not be able to see a favorable future where you’re at.

Investing Out-of-State

If you decide to invest out-of-state, you can greatly increase your options. You can literally choose any location, any market and invest in properties there. Whether you want to invest in Florida vacation homes and coastal villas or homes in the suburbs of Detroit, the sky’s the limit. You can make your investment fit your price point and interests.

By investing out-of-state, you can put your money to work in markets with high ROI. You pick and choose which markets you’re interested in, and which ones are rising stars in the real estate investment scene, ignoring your own market’s changes.

Investing out-of-state also allows you to scale based on your needs. For many would-be investors, their local market is priced too extravagantly to make real estate investment prudent. The cost of living in a different state, just a few borders east or west, might be considerably lower. That means you can snatch up excellent properties at a much lower cost than you might in your own market.

Even better, you can snag those investment deals on excellent properties that would go for three to four times as much, if not more, in your own local market. Your purchasing power becomes much stronger in other markets, because everything’s relative.

Challenges of Out-of-State Investments

There are still some challenges to these remote investments. First of all, you have to learn who you can trust and maintain the peace of mind that comes from having easy local access to your investment. You also have to be able to trust that the property you’re investing in is what it’s advertised as.

The property is also more difficult to visit if you like to be hands on. You might have to fly out to visit the property, which some people enjoy but others are seriously bothered by. If you are the type of investor who prefers the more passive turn-key approach, this is an excellent opportunity.

Finally, the market won’t be what you’re used to. Nothing will be quite the same as being there and immersing yourself in the market, but you can learn and study. You just have to rely on someone else to have knowledge of the nuances of the market.

Doing Out-of-State Right

There is a solution to all of the challenges of real estate investing outside your state. When you find a reputable, proven company to handle your turn-key real estate transaction, you have someone you can count on to know the market you’re investing in. Here are the main reasons you should find a partner to work with you on your out-of-state investments.

  • They can keep a more educated eye on the market, since they know all of the nuances of that area.
  • They’ll serve as your presence near your investment, keeping everything on track, so you don’t have to make numerous trips to the property.
  • If the turn-key real estate investment firm is reputable, they want you to succeed. This means they’ll do anything they can to make sure you do succeed.

The question becomes, whom can you trust? You want to make sure you engage in a partnership with a firm who is reputable, knowledgeable and engaged in your market. Referrals from other investors are key, so be on the lookout for like-minded people who have been there and done that.

You should also investigate what the turn-key operation offers you, and what their fee or cut of your profit is. Ideally, you’ll want a partner who can help you throughout your investment lifecycle, from acquiring the property to managing it.
