I am frequent computer user. Of course it’s interesting to know how danger for my health computer can be. Working with computer for whole day is not rare nowadays. If it’s an aspect of our work or if we use computers just for fun, there are certain risks involved with prolonged computer use. 1. Eye Disease It’s the first what occur to us, when we talk about computer harm (right?). Prolonged computer use could be linked to glaucoma, especially among those who are short-sighted. Our eyes are very badly affected by how long you stare at that bright screen. We stop blinking and start staring which makes our eyes strain and dry out. Make sure you look away from the screen and close them for a few seconds every few minutes. We can find many information about eyes health, as Snuz made. And it’s very important not to forget about our eyes while working on computer. 2. Bad Posture Bad posture is enemy number one. Check your posture now! You should be able to reach the keyboard and mouse whilst bending your elbows at 90 degrees, with your shoulders relaxed. If you are stretching, this could cause problems. Your back should be straight and the top of the monitor should be just below eye level. If your monitor is to the left or right of your keyboard you are putting strain on your neck. Long periods of time at the computer while blogging, working or reading often leads to pain in the lumbar region of the back. Neck and shoulder problems also result from poor seating and the poor organization of equipment on the desk (stretching for the telephone or files etc). 3. Hurting Hands Your hand and wrist ache after working at the computer all day, and they sometimes start feeling numb. Research in recent years has found that things like typing and sewing rarely cause carpal tunnel. Wear splints while you work to keep your wrists from bending too high or low, and use a keyboard tray or adjust your chair so the keyboard and mouse are below your elbows and your wrists are level. It is really important to give your fingers, wrists and hands a break from resting on the keyboard all day. A tennis ball is a great way to do this. Every time you need to think you should grab the ball and give it a few quick squeezes. This will do wonders for your joints and muscles. 4. Computer Stress Injuries Many people suffer from structural problems related to the physical stress of sitting incorrectly, or for too long in front of their computers. So there are chances you’ve experienced a fair amount of computer stress, from minor frustrations here and there to a virtual visit to computer hell. High levels of stress can kill you, don’t make mistakes! Highly stressful workers have a higher risk of developing heart diseases and even cancer. So make sure that you can manage your stress. Start making something to reduce it, don’t wait till computer stress will be the main problem in your life. Taking frequent breaks is an important step in preventing repetitive computer stress injuries. Thus, it shows up that there are several problems that occur with prolonged computer use. It is also clear, however, that if certain rules of using computer are observed the risk of any of these problems can be minimized and computer users affected with computer related disorders can avoid or treat them. I consider that persons should have active lifestyle and an ergonomic computer work station, thereby even hardly computer working can’t affect their health. What do you think?

Internet, as most of us know, is a large network of networks, which communicate with each other by means of data packets. Internet is regarded as the largest information base. Today, Internet has become an integral part of our daily lives. We depend on the Internet to update ourselves about current news and rely on the communication platform it offers to get in touch with our near ones. The information from all around the world is just a click away, thanks to the Internet. Internet has surely affected the society positively. With the onset of the Internet, access to information has become easy. Internet has served being an efficient and organized storage of information. Internet search engines are the best information retrieval systems that are functional over the Internet. Typing in a simple search query to a search engine fetches you thousands of search results. Moreover, the ranking strategies adopted by the search engines ensure that the most relevant results are delivered to you on priority. The search engines crawl over all the information that seems relevant to your search query.

Professionals working in physically distant locations can collaborate their efforts, thanks to the Internet.

Nine Themes of Digital Citizenship

Between cell phones, social media Web sites, and online gaming, children today seem to have more outlets for interacting with each other virtually than they do for interacting with each other in person. However, with all of the good social interaction that is done as a result of these technologies also comes the bad. In addition to the physical and verbal bullying that may take place at school, cyber-bullying in the form of harassing text messages and derogatory posts on children’s Facebook pages is now commonplace. Even though it may not take place in person, the emotional and psychological effects of cyber-bullying are just as destructive. Since new media and cell phones are harder to track and monitor, parents need to take preventive measures that can help minimize the effects of cyber-bullying on their children. 

There is little doubt that, in a considerably short period of time, the Internet has grown enormously in both its applications and number of users.

Often, people who are victims are also bullies. Before you feel too bad for yourself, take the quiz below to find if you, too, are part of the cyberbullying problem! Rate yourself on the following point scale according to if, and how many times, you have done the below activities. Give yourself 0 points if you’ve never done it, 1 point if you have done it 1 or 2 times, 2 points if you have done it 3-5 times, 3 points if you have done it more than 5 times.

Anyone with doubts about the importance of workplace culture only had to read Greg Smith's stinging resignation letter to Goldman Sachs to be reminded, in quite a visceral way, of the critical role it plays.

Effects of Moderate Use A moderate amount of computer use and game playing doesn't seem to affect social development. The social behavior of moderate computer users and nonusers was roughly the same in terms of sociability and relationships with friends and family. However, heavy computer users tended to believe they had less control over their lives than their classmates, a possible indication of inadequate socialization. Increased Hostility and Aggression After the massacre at Columbine High School in 1999, researchers and educators paid more attention to violent video games such as Doom, the daily game of choice for one of the two teenage killers. Many studies show that violent TV shows increase aggression and hostility in both children and adults. It appears the same is true of computer games. The key variable appears to be a preference for violent games, rather than the amount of time a child plays such games. Even playing Mortal Kombat for a short time increases a child's hostility and aggression. Violent computer games also desensitize children, who show less empathy and willingness to help others, according to research cited in "The Future of Children." Brain Drain In a small study of 18 Chinese university students, published in the "PLos ONE" journal and reported on Mail Online, kids who played games on their computers at least eight hours a day, six days per week showed alarming amounts of atrophy in parts of their brain, as measured by MRI scans. The scans also found abnormalities in the white matter of the brain, which coordinate communication between different areas of the mind. On Mail Online, Dr. Aric Sigman of the Royal Society of Medicine called the July 2011 report a "wake-up call." Experts fear that in addition to cognitive damage, heavy Internet use might reduce the inhibitions and decision-making ability of children, leading to damaged relationships with family members, peers and authority figures.

In Israel's capital yesterday, Mitt Romney "added one more flat note to the image of the Republican presidential hopeful's gaffe-prone international foray," the Christian Science Monitor claims. In the New York Times account, Romney "offended Palestinian leaders . . ., thrusting himself again into a volatile issue while on his high-profile overseas trip."
