Article: Surrounded by far - away mountains and nearby downtown buildings, a large open field was filled with lines of blue and white houses. Several kids were laughing and playing table tennis inside a play room. Some old men were playing Chinese chess and a crowd of women chatting in front of two TV sets. Two weeks after the deadly earthquake, the first batch of 1,500 people inprefix = st1 /Dujiangyan,SichuanProvince, one of the worst earthquake - hit cities, has finally settled into a peaceful life in a newly built temporary community. "Compared with tents, these simple houses make us feel more at home. My grandchild can go on with his study here," said an old woman. These one - floor buildings are totally different from their old homes. Instead of cement and bricks, the houses are made of light- weight steel or foamed plastic and can stand a 7 - magnitude earthquake. Each of the houses, featuring about 20 square meters, serves as a three - person family unit. The units have three beds and electricity. Each has its own postal address. Communal facilities will include showers, toilets and refectories . It is also planned that there should be one primary school, one hospital and one supermarket for every 1,000 homes. Everything will be free to the residents in possession of their identity cards, and work has already started in looking for jobs for the community. "More than 1.5 million such _ houses will be built inSichuan, which are expected to be in use for at least three years," said Minister of Housing and Urban - Rural Development Jiang Weixin.

Article: American schoolchildren often wear uniforms if they attend religious or other private schools. Most public schools do not require uniforms. But over the last ten years or so, more of them have moved in that direction, including high schools. Students may have to wear a specially purchased uniform. Or they may just have to dress alike~for example, white shirts and dark color1ed pants or skirts. Even schools that do not require uniforms generally have a dress code or other rules about what they consider acceptable. Policies commonly ban clothing that shows offensive images or words, or simply too much skin. Items like hats may be not permitted because ,for example, different color1s may be connected with violent gangs. Some parents like the idea of uniforms. They say it means they do not have to spend as much on clothing for their kids. Others, though, argue that uniforms represent an unnecessary cost There are also debates about whether uniforms or other dress policies break civil rights. Students and parents have taken legal action against school dress requirements. Just last week, a judge blocked a middle school in Napa, California, from enforcing a dress code unless families have a way out of it The American Civil Liberties Union of Northern California brought the case for the families of several students who werfe punished Most attention centered on a girl who wore socks with the Tigger character from Winnie the PooK The school said its clothing policy, including no pictures of any kind, was needed to control a growing problem with gangs. The families argued that the policy went against free speech rights as guaranteed by the United States and California constitutions. The United States Supreme Court says student expression is protected as long as it does not harm the work and discipline of a school.

Article: Telemedicine is the name for when doctors give advice to patients by telephone or the Internet, or when health care providers in rural areas connect with specialists in big cities. Telemedicine has existed for a long time, but the rise of smart phones, tablets and webcam-equipped computers is raising telemedicine to new levels. Some health care systems in the United States now offer Virtual Urgent Care, patients see a doctor by video chat without having to leave home. Diana Rae is a nurse educator in the western state of Washington. She recently showed how Virtual Urgent Care works. She used an iPad tablet and skype -- the video chat service. Doctor Green has the patient describe her symptoms, then the doctor performs a physical exam by demonstrating what he wants her to do. Doctor Green decides that the problem is a silence infection. For medicine, he prescribes an antibiotic. He says about 3 out of 4 patients have health problems that can be treated like this --through Virtual Urgent Care, that means a video chat could replace a visit to the doctor's office. The Franciscan Health System is based in Tacoma, Washington. Franciscan charges $35 for this kind of virtual house call, that is much less than the cost of going to an emergency room, a doctor's office or an urgent care clinic. After trying the video conference, Diana Rae says, "I would've paid twice that for the convenience of getting taken care of without having to sit in a waiting room, wait, and get exposed to everyone else's germs." Franciscan has a deal with a company called Carena to add virtual urgent care by Skype or phone. Carena is one of several companies doing this kind of work around the country. But a company official says state rules have not kept progress with developments in telemedicine. The workers who provide virtual urgent care must be separately licensed in each state where the company does business. For now, that means Carena doctors can treat patients in Washington state and California for example, but not in neighboring Oregon or Idaho.
