HIV Education in the Schools Across America

AIDS has devastated the lives of many citizens in the United States. The Centers for Disease Control and Prevention (CDC) indicates that the number of AIDS infections among young Americans between the ages of 13 to 25 rose nearly 20 percent, and approximately 50 percent of new infections are among individuals who are younger than 25 years of age. Therefore, finding better methods to communicate the risk of AIDS transmission are greatly needed to protect our young people and preserve the next generation.

Young people in the United States are at a persistent risk of HIV infection. This risk is especially notable for youth of minority races and ethnicities. Continued HIV prevention outreach and education efforts, including programs on abstinence and delaying initiation of sexual relations, are required as new generations replace the older generations that benefited from earlier prevention strategies.

I believe that there should be more HIV and AIDS education in the school systems across America. I feel that this is an area of education that we could improve to protect and preserve our next generation. There are two reasons that I feel this way. My first reason is to prevent a student from being discriminated against, and the second reason is giving education to the students on preventing the spread of this disease.

My first reason for believing there should be more education about HIV and AIDS in the school system is the way I was treated when I was diagnosed with HIV. I was diagnosed with HIV at 14 years old and due to the lack of education to the teaching staff in the earlier years; I wasn’t permitted to attend class in a regular school setting. Instead I was forced to be home schooled by the board of education, (homebound program) in which I wasn’t taught all the subjects as a regular student would be. I wasn’t taught mathematics at a high school level so when I decided to attend college I had a lot of difficulties in the area of mathematics. On the other hand, English was drilled into my head like a nail, which I am grateful for. The reason for this was that my homebound teacher was an English Professor before she started teaching in the homebound program.

Even though I wasn’t taught as well as those students attending classes in a regular school setting, I have become an excellent student in college despite my difficulties in math. I do believe, however, that the school system has gotten better. I haven’t had any problems with discrimination while attending college. That, at least, is a good thing!

Secondly, I feel that if there had been more education on the prevention and spread of this disease, I might not have contracted it. Had I known about the risks of this disease, I may not be infected today. Even though I contracted HIV through a blood transfusion, maybe if I had been more educated on the ways it is transmitted, I could have somehow prevented myself from becoming infected.

Therefore, I believe that there should be more education for students. The students are our next generation. They should be educated about the risks of HIV infection. I feel it should be a requirement for the schools to inform students about the dangers of the disease as well as the myths of being around someone who is infected.

Even now I feel I have to be careful when I disclose my diagnosis, which prevents me from making friends for fear of being rejected. I feel that if there were more education, I could feel more comfortable talking about my situation of having this disease. Ultimately, I wouldn’t be afraid of causing a panic among my peers. Finally, I believe with more education it would prevent the rise of students becoming infected with this disease. I believe that it is our obligation to protect the next generation.

Home Theater Sound Systems

When you get a home theater, you are probably really excited about your new TV. But a lot of people over look that maybe getting a sound system in addition to the speakers that come with the TV is a good idea. You can get surround sound, or just large speakers to attach to the TV. Getting clear sound along with the new flat screen clear picture helps to make for the ultimate movie experience. Whatever you decide to do, you can be sure that you are going to be getting the best movie experience possible when you combine a new TV with a new sound system. Surround sound is most popular for when people buy Home Theaters, and they are perfect to replicate that movie like room. In a movie theater, speakers are located all around you, not just in front of you. Duplicate that feeling with better speaker quality and surround sound!

Surround sound comes in a lot of different kinds of features, from stand alone speakers that you can put anywhere in the room, or wall mounts that you put in each corner of the room. Whatever you decide to do with your speakers, you will find that you can get great sound quality, from even the cheapest of surround sound systems you buy. You do not need to worry about blowing huge amounts of money, and you can find a sound system that fits your budget and all of your movie watching needs.

If you do not want to get surround sound, then additional, high quality speakers are also available that plug right into your TV. This is the best way to get great sound and not have to worry about installing a sound system. Speakers are relatively inexpensive, and you can get them easily at any store, whether it’s the local sound store or just at Wal-Mart. Speakers just plug right into your TV, and you do not need to worry about lots of complicated wires. The only thing you have to do is to install and get ready to watch your favorite movie in your Home Theater!

3 Ways to Create a Motivational Collage

One powerful collage theme is motivation! But in order to create a motivational theme you first need to write down a goal. Start with a simple goal that relates to something personal that you are working to toward.

For example, I often have freshmen students in beginning art classes create a goal collage on their major. Where do they want to go? Where do they see their selves after graduation.

Consider the following 3 simple steps.

1. Sort and gather images that will motivate you to reach a goal. For example, if you are remodeling your house only gather those images that relate to that process. This would not be the collage that has images of your last birthday party.

2. Think possible not impossible

It is easy to get discouraged when doing your collage if you think about cost and other limitations. Stay focused on your dream. It can happen. That is why you are creating a collage with a goal in mind.

3. Have fun!

Think out of the box. Mix your images with powerful and inspiring words that will help you achieve your goals,

So write out your goals. Start searching for your images and get started.

If you need help doing goal setting I have a great coach for you.

Send an email to cegoals@aol.com. She will work with you to create solid goal statements using the SMART method. That stands for specific, measurable, attainable, realistic and tangible.

And remember you can always contact me for any suggestions on your collage making process.

5 Daily Habits That May Shorten Your Life Span

The human body is considered as the greatest wonder. You are the person who is responsible for habits that may shorten your life span. No one else is to blame. The body of the humans is believed to be built for living more than a century, but the present situation shows that only the half of that can be taken as an average life span. The life span is shortened mainly due to the habits developed by the humans. Those habits can harm the whole system adversely. Any habit will take a fixed period of time to turn into a regular pattern. Avoiding the habits which are harmful is not such a Herculean task. So it is high time you reclaim the control of your life and live. There are mainly five habits that shorten your life span and that should be avoided.

Unbalanced Diet

You take in food to provide your body with the necessary nutrients which are inevitable for the proper working of the various systems of the human body. But think once more, do your diet has all the essential nutrients? If your body is not getting the vital nutrients it will not function properly. This is sure to shorten your life span considerably.

Drugs

Taking in drugs and toxic substances is another grave problem. Alcohol and such other intoxicating substances are silent killers of your body organs. Alcohol can cause damage to you heart, liver and such other vital organs. The effect of cardiac and liver problems is well known to every one. Thus the intake of intoxicating substances can shorten your life span dramatically. Not just that, these substances can make the living period itself as painful as hell.

Tobacco

Tobacco also comes under the category of toxic substances. It can destroy the cells in the lungs. Smoking is a major cause of cancer around the world. Chewing of tobacco and other like substances can cause mouth cancer. Once you are affected by these diseases, it will be a great distress not only for you but for the people closer to you also. Smoking is a huge factor that shortens your life span.

Stress

The busy life has a very bad level of stress. Stress has a lot to do with the health of a person. The life of a person can be worth living only if his mind and body work in perfect harmony. The mental breakdown is one of the main reasons which leads people to the habits of alcohol consumption, drugs and smoking. Avoiding stress can work wonders in one’s life. Stress is the sure by-product of this ultra modern era, but there are ways to avoid it. It should be avoided. Otherwise you will be the hunt of many diseases and your life span will also be affected.

Lack of Exercise

With the development of technology the human body is having very less workout. The adverse effects of having less or even zero exercise is very disturbing. If your body is not getting enough exercise, the calories taken in will get deposited in different parts of your body. These unwanted fat deposits will eventually cause health problems

Google Redirect Virus Fix – How to Get Rid of Google Virus

Infecting users via internet exposure and nooks and crannies found in unsecured browsers are the main causes of the redirect virus. So where does one inject the use of Google redirect virus fix? In order to properly employ its use first it is essential to understand what this threat is and what it does. The redirect malware lives up to its name, the infection causes a hijacking of any search or website visit a user plans to make. Instead of finding their site of choice the virus redirects them to fake websites containing ads and even corrupted pages.

The following fake errors are displayed by the vius

  • Internet explorer cannot open web page
  • filename.exe is not a valid win32 application
  • Setup files are corrupted Please obtain new copy of program

Being a browser hijacking utility it manages to infect browsers like IE and Firefox and then redirects internet users to the following malicious sites.

  • clearask.com
  • brittaniasearch.com
  • go.Google.com
  • web-analytics.Google.com

The redirect threat is capable of disabling activated firewalls and security software which can then lead to a remotely accessible system. This allows hackers to have access over personal information such as login names, passwords, financial records etc.

What are the symptoms to consider when one wants to implement a Google redirect virus fix?

· An unknown change of desktop background

· Changes homepage

· Browsers such as IE and Firefox slows down noticeably

· Corruption of registry files thus resulting to the dreaded “Blue Screen of Death”

· Contamination of messengers, freeware and email attachments are also sure signs.

How does Google redirect virus fix work?

1. Select Show Hidden Devices under Hardware Device Manager in your Windows Control Panel.

2. Search for “TDSSserv.sys” right click Disable. Do not select Uninstall otherwise the infection will reappear once the computer is restarted.

3. Reboot the pc.

4. Immediately update antivirus software and the Google redirect virus will cease to exist in your workstation.

It pays to be vigilant and alert when using the internet. Avoid malicious sites and constantly scan your system and update your security tool to avoid contaminations. It is also best not to rely on one antivirus software alone having another reliable application can help sift through the threats that the other was incapable of detecting.

Building a Career Through Online Education Courses

Education is a systematic process of acquiring knowledge and skill necessary for personal growth and development. The practical application of education in a specific field of study can jumpstart a professional career or establish a foundation for possible business ventures. Making an investment in education can be one of your most significant and wisest decisions in life because of its immediate impact to your future. Distance education plays a vital role in connecting educators and learners worldwide, breaking the barriers imposed by time constraints, distance, disabilities and socio-economic status. Distance education courses are being offered by Open Institutions to answer the call for internationally recognised quality education and training. Whether you are a student who just started on the path of learning, a professional in your field of study and want to further your education through advanced and specialized programs, or a person who is restricted by travel or health concerns, online courses definitely have the answers for you.

Many individuals are asking on how effective distance education when delivering the methodologies of teaching. Online education classes are as effective as traditional face-to-face instruction done in colleges and universities. The keys to establishing a successful online study depend on the dedication and focus of the learner, and timely peer-support by the open institution. The people behind the curriculum and online support offered through distance education are professionals and experts in their field, so you can be sure of having the quality education and training that you are looking for. Online instruction is divided into four major classifications, namely: voice, video, data and print. Voice or use of audio as medium of communication includes the telephone, tapes, radio and audio-conferencing.

On the other hand, videos may come in the form of instructional tapes or CDs, or combined with voice and data as file attachments. Print media can be in the form of instructional books, guides, course outlines or assessments which are delivered through courier or mailing system. Data is the widely used form of instruction due to the advances in technology in computers and the internet. Information is transmitted electronically and may be in the form of Computer Assisted Instruction (CAI), Computer Managed Instruction (CMI), Computer Mediated Education (CME), or a combination of any of these. The delivery of education and training became better, faster and economical since all the instructional materials and methods of teaching are coursed through e-mail (electronic email) or e-fax (electronic facsimile), online conferencing and other World-Wide Web applications. This would include advances in communication by utilizing Voice over Internet Protocol (VoIP). By making use of all the available communication media, online learning study is delivered fast and efficient.

Distance learning has many advantages that individuals on different levels of learning can take advantage. It provides the flexibility of choice when you want to finish a course or where you want the training to take place. Assessments and projects are given at the end of a specified topic, submitted to education professionals and experts of their field for evaluation, and then feedback is given to determine if a learner is to advance to the next level or if further reading is required prior to advancement. You can never be too old or too young in order to start a life changing career, or build the basic foundation to start a new business. All you would need is the proper self-motivation and focus so you can look forward and fulfill your dreams in life.

Flu Virus Research

The critical part in the research is to understand how influenza virus spread and mutate and is the key to preventing pandemics by discovering preventive, diagnostic and treatment methods.

According to the World Health Organization (WHO), influenza viruses that occur in animals can infect humans, and later develop to pandemic strains. Several research areas have been outlined by the WHO relating to the animal/human influenza interface that could have a profound impact on protecting human being.

The Working Group of WHO on Influenza Research at the Animal/Human Interface was setup in 2005 to encourage basic studies into animal influenza viruses, with the aim to find out the cause the viruses can infect people.

ON-GOING STUDIES

Studies are on-going on avian influenza viruses, particularly H5N1. Researchers aim to discover the prevalence of avian influenza viruses in domestic animals and birds, understand the molecular basis of   transmission  of viruses from animals to people, assess the role of migratory birds in the  transmission  of the viruses, and evaluate the human immune response to infection with avian influenza viruses.

Studies are also being done on H1N1, a novel strain which is the causative factor of the current influenza A pandemic and researchers succeeded developed a vaccine which approved by the US Food and Drug Administration.

PUTTING VACCINES TO THE TEST

The scientists from the US National Institute of Allergy and Infectious Diseases (NIAID) play an important role and work in collaboration with medical research institutions worldwide to find better ways to prevent, diagnose and treat seasonal and pandemic influenzas, including influenza A (H1N1).

The trial is being conducted through the NIAID-funded national network of Vaccine and Treatment Evaluation Units (VTEUs). Safety data will be collected and assessed continuously throughout the trial by an independent safety monitoring committee and investigators.

STUDYING THE NATURE OF THE FLU VIRUS

Other than vaccine research, NIAID scientists are also investigating the basic biology of influenza. The data collected will assist in designing diagnostics that are more accurate and faster, cost-effective and portable. NIAID is also investigating host immune responses to the virus in animal models and people, and studying influenza epidemiology.

For treatment, NIAID supports research being conducted to develop new and effective drug combinations and examine the mechanisms behind emerging drug resistance. This effort is supported by innovative new technologies to design drugs that target specific cellular processes and viral proteins.

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.

IPv4 Vs IPv6 (Advantages and Disadvantages)

We can see the rapid growth of internet users in last few years and this increase also create challenges for internet management groups, stake holders and service providers. Day by day infrastructure of internet is expanding and we can even enjoy the service of internet in villages and remote areas. Increased of usage also increase online devices. In start internet protocol addressing (a specific IP addressing for each online entity) was designed on 32 bit and this scheme IP version called IPv4.IPv4 addressing is like 203.128.076.001. decimal is used to make the IPv4 addresses more palatable for humans and a 32-bit address becomes 4 decimal numbers separated by the period (.) character. If we calculate these decimal values and we can get the total number of devices can be participate on this protocol (256x256x256x256) = allows for 4,294,967,296 addresses. It is about 4 billion of addresses and in early days of internet no one can think, 4 billion slot will be full. here we shall discus some disadvantages of IPv4 as we have seen addressing capability problem and after that we shall go through the solution which will replace IPv4 and addressing structure of the new addressing scheme. we shall go through some disadvantages of IPv4 and new features of IPv6.

Rapid Growth of the Internet and the Exhaustion of the IPv4 Addressing

IPv4 allows for 4,294,967,296 addresses which is about 4 billion and IP allocation limits the public IP addresses to a few hundred million. Cause of this limitation companies using NAT (Network Address Translator) to map single public IP to multiple private IP addresses.

IPv4 Security at IP Level

When we communicate at public medium we need to encrypt data to maintain security and privacy. After a passage of time we have now security for IPv4 packets. This security knows as internet protocol security or IPSec but this is an optional for IPv4.

Internet Backbone Maintaining Large Routing Tables

In IPv4 network IDs allocation is very critical and currently more than 87000 routes in the routing tables of internet backbone routers today. The routing infrastructure is based on flat and hierarchical routing.

Quality of Service Concern in IPv4

Now a days internet users are not only limited with browsing and searching data. Current users are well aware of text and voice and video chat and video conferences and online video libraries. This kind of communication need real time data transfer for quality of service. Normally for these kind of services we use UDP (User Data-gram Protocol) or TCP (Transmission Control Protocol).IPv4 TOS field has limited functionality and, over time, has been redefined and locally interpreted. Additionally, payload identification that uses a TCP or UDP port is not possible when the IPv4 packet payload is encrypted.

IPv6

As we can see we have some basic problems in practice of IPv4 now we will check some new features of IPv6. here I like to describe the some of basic features of IPv6. Deployment of IPv6 is a big challenge for internet management groups, stake holders and service providers. It is difficult but not impossible. We can see benefits of IPv6 here. Biggest upgrade jump from IPv4 32 bit to IPv6 128 bit.

IPv6 Header Format

New header is designed to minimize header overhead. by moving both nonessential and optional fields to extension headers that are placed after the IPv6 header. IPv6 header is more efficiently processed at intermediate routers and that generates efficiency. IPv6 is 4 time larger than IPv4 and its header size is twice than older version.

IPv6 Large Addressing Space

In IPv6 source and destination addresses is based on 128 bit. 128 bit addressing can produce over 3.4 x 1038 possible combinations. Currently we can say this is enough but who know about future may be it also face same problem like IPv4 after some decades. 128 bit addressing allow us multiple levels of sub-netting and address allocation. So we can say that we have plenty of address for use in future.

Addressing and Routing Infrastructure Efficiency in IPv6

IPv6 designed to create an efficient, hierarchical, and summarize able routing infrastructure that is based on the common occurrence of multiple levels of Internet Service Providers. It reduce the size of routing table of backbone routers. Which is can cause of efficient internet experience.

Security features is now built-in

IPv6 has been design to support IPsec (AH and ESP header support required) also support mobility version Mobile IPv6. IPSec based on two types of extension headers and a protocol to negotiate security settings. The Authentication header (AH) provides data integrity, data authentication, and replay protection for the entire IPv6 packet. It is better form developers who built-in security features in development of IPv6 rather we bolt on later.

Quality of Service (QoS) of IPv6

As we have already seen about the UDP and TCP protocols for streaming and other multimedia services on internet. Cause the usage of these services are increasing day by day IPv6 have a flow level field in its header which make better and special handling for packets from source to destination. Data traffic is identified in the IPv6 header, support for QoS can be achieved even when the packet payload is encrypted with IPSec and ESP.

The Basic Principles of Preventing Infection

Basic Infection Control refers to measures designed to prevent the spread of infections or potentially infectious microorganisms to health personnel, clients and visitor. Various infection control measures are used to decrease the risk of transmission of microorganisms in hospitals.

Principles of Basic Infection Control

1. Microorganism move through space on air currents. Avoid shaking or tossing linens as these motions create currents on which these microorganisms can be transported. All isolation room doors should be closed to stop air currents.

2. Microorganisms are transferred from one surface to another whenever objects touch. When a clean item touches a less clean item, it becomes “dirty” because microorganisms are transferred to it. Keep your hands away from your hair and face. Keep linens away from your uniform. Always keep clean items separated from dirty ones, any object dropped to the floor is considered dirty.

3. Microorganisms are released into the air on droplet nuclei, whenever a person breathes or speaks. Coughing and sneezing dramatically increases the number of microorganisms released from the mouth and nose. Cover mouth when coughing and sneezing. Wash hands thoroughly.

4. Microorganisms are transferred by gravity when one item is held above another. Avoid passing dirty items over clean items or areas because it is possible for the microorganisms to drop off into a clean item or area. When storing items in a bedside stand, place a clean items on upper shelves and potentially dirty items such as bedpans on lower shelves.

5. Microorganisms move slowly on dry surfaces but very quickly through moisture. Use dry paper towel when you turn off faucets. Dry both basin before placing on bed side for storage.

6. Proper hand washing removes many of the microorganisms that would be transferred by the hands from one item to another.

Universal Precaution

1. Wear clean examination gloves for listed body fluids: Blood, semen, vaginal secretions, CSF, synovial fluid, pleural fluid, pericardial fluid, amniotic fluid, etc.

2. Wash hands:

  • a. Immediately after contact with body substances containing blood
  • b. Between patient care
  • c. Immediately after gloves are removed.

3. Wear masks and protective eyewear when appropriate.

4. Wear moisture-proof apron when appropriate.

5. Wear utility (household rubber) gloves appropriately

6. Dispose of equipment and secretions properly

7. Wear sterile gloves appropriately

8. Handle specimens of blood and listed body fluids appropriately

9. Handle soiled linens correctly:

a. Hold linen away from uniform

b. Do not shake or toss linen

c. Transport linen contaminated with blood or bloody fluids in leakage resistant proof bags.
