Beijing, Sept. 13 (Xinhuanet) -- A fear of taking antidepressants often results in people's reluctance of going to see the doctor when they are suffering from depression, a study find.The finding was published Monday in the U.S. journal Annals of Family Medicine.The researchers from the University of California investigated 1,054 adults on why they wouldn't tell the doctors about their depression symptoms, as well as any possible mental disorder.Among the participants, 43 percent admitted that they had been reluctant to tell the doctor about their depression symptoms.Their top concern was the possibility of being prescribed an antidepressant -- a worry voiced by 23 percent of the whole study group.Another 16 percent thought dealing with "emotional issues" is not the doctor's job. And a similar percentage worried that the diagnosis of depression may leave a negative record on their medical records.The study would be helpful for looking into the reasons that patients harbor the attitudes that they do, said Dr. Hellerstein of the New York State Psychiatric Institute and Columbia University Medical Center in New York.

NEW YORK, July 15 (Xinhua) -- A Gallup survey released on Friday found a total of 59 percent of Americans support a ban on smoking in all public places.The July 7-10 survey among 1,016 national adults showed a change in the public's attitude toward public smoking ban. In 2001, when Gallup first asked about a ban on public smoking, 39 percent were in favor, an attitude that stayed roughly the same through 2007.At the same time, the poll also found that fewer than two in 10 people supported the idea of making smoking totally illegal.According to the American Lung Association, 27 states plus the District of Columbia have passed comprehensive smoke-free laws. A New York City law bans smoking in virtually all public places, including outdoor plazas and beaches.

CANBERRA, Aug. 29 (Xinhua) -- Alzheimer Australia on Monday released a GPS device for people with dementia, in a move to give them greater independence, while reducing the burden of missing person searches for police.The technology has been using in New South Wales of Australia, and is now available for people in state Victoria.The Safe2Walk locater can be worn by people with dementia on a lanyard around the neck or clipped onto a belt. Families can log- on to the connected website and see where the person is.The device updates the person's location every 60 seconds, reducing stress for carers so they know when a person with dementia might be wandering.It also works as a mobile phone, letting the person wearing the device to make instant calls to family.According to Alzheimer's Australia's research manager Jason Burton, the device aimed to stop vulnerable people getting lost, with research showing about 40 percent of people with dementia went missing at least once."In 99 percent of cases the carer has gone to pick them up, but there was one case where they couldn't and the police were able to contact us to get the exact GPS location of this person to rescue them," Burton told Herald Sun.A Victoria Police spokeswoman said while it could not endorse a specific product, if the device could alert carers when a person with dementia first became disorientated, the response could help avoid a large-scale police search.Mina Sapounakis, who's father has worn the Safe2Walk device, said it has given her family a sense of calm."We could go grocery shopping without stressing and rushing back home quickly to check on Dad," she said."There were a few times he had gone wandering and we were able to easily find him without having to call the police."The Safe2Walk GPS costs under 15 U.S. dollars a week for rent.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Microsoft released on Tuesday a test version of Windows 8 to developers, posing to regain ground of the tablet market dominated by Apple and Google.At its developer-focused BUILD conference held in Anaheim, California, the software giant handed out new Samsung tablet computers with a test version of the code-named "Windows 8," the first detailed preview of the system for developers and people outside Microsoft.Generally expected to be launched in fall 2012, Microsoft did not say when the system will ship or its price.Microsoft Windows President Steven Sinofsky introduces the new tablet running a test version of its touch-enabled Windows 8 at the Build conference in Anaheim, California September 13, 2011Featuring a home page filled with colorful application tiles, the new system boots up in seconds. Microsoft said the system will run on low-power ARM-based chips that power smartphones and tablets. Windows 8 also introduces a new "Metro style" interface, which run full-screen and users can multitask in two at a time."We reimagined Windows," said Steven Sinofsky, president of the Windows and Windows Live Division at Microsoft, in his keynote address to the thousands of developers in attendance. "From the chipset to the user experience, Windows 8 brings a new range of capabilities without compromise."Analysts said the new system is consumer-oriented and intuitive but it will take time to see whether it is an "iPad killer."As professionals and consumers began to spend more time on smartphones and tablets, Microsoft has not got a significant bite of the market, losing ground to Apple's iPad and devices running Google's Android system.

LOS ANGELES, June 10 (Xinhua) -- The Aquarius/SAC-D observatory, NASA's first ever satellite to study the saltiness of Earth's oceans, is in excellent health after its launch early Friday, initial telemetry reports showed.The observatory rocketed into space from Vandenberg Air Force Base in California atop a United Launch Alliance Delta II rocket at 7:20:13 a.m. PDT (10:20:13 a.m. EDT).Less than 57 minutes later, the observatory separated from the rocket's second stage and began activation procedures, establishing communications with ground controllers and unfurling its solar arrays, NASA's Jet Propulsion Laboratory (JPL) said.During the next 25 days, the Aquarius/SAC-D service platform will be tested and maneuvered into its final operational, near-polar orbit 408 miles (657 kilometers) above Earth. Science operations will begin after the observatory's instruments are checked out. This commissioning phase may last up to 65 days, JPL said.Aquarius will map the global open ocean once every seven days for at least three years with a resolution of 93 miles (150 kilometers). The maps will show how ocean surface salinity changes each month, season and year. Scientists expect to release preliminary salinity maps later this year."Aquarius is a critical component of our Earth sciences work, and part of the next generation of space-based instruments that will take our knowledge of our home planet to new heights," said NASA Deputy Administrator Lori Garver. "The innovative scientists and engineers who contributed to this mission are part of the talented team that will help America win the future and make a positive impact across the globe."Aquarius will measure salinity by sensing thermal microwave emissions from the water's surface with three microwave instruments called radiometers. When other environmental factors are equal, these emissions indicate the saltiness of surface water. A microwave radar scatterometer instrument will measure ocean waves that affect the precision of the salinity measurement.Because salinity levels in the open ocean vary by only about five parts per thousand, Aquarius will be able to detect changes as small as approximately two parts per 10,000, equivalent to about one-eighth of a teaspoon of salt in a gallon of water."Data from this mission will advance our understanding of the ocean and prediction of the global water cycle," said Michael Freilich, director of NASA's Earth Science Division in the Science Mission Directorate at agency headquarters in Washington. "This mission demonstrates the power of international collaboration and accurate spaceborne measurements for science and societal benefit. This would not be possible without the sustained cooperation of NASA, CONAE and our other partners."The Aquarius/SAC-D (Satellite de Aplicaciones Cientificas) observatory is a collaboration between NASA and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE).Aquarius was built by NASA's JPL and the Goddard Space Flight Center in Greenbelt, Maryland. NASA's Launch Services Program at the Kennedy Space Center in Florida manages the launch.JPL will manage Aquarius through its commissioning phase and archive mission data. Goddard will manage Aquarius mission operations and process science data. CONAE is providing the SAC-D spacecraft, optical camera, thermal camera with Canada, microwave radiometer, sensors from various Argentine institutions and the mission operations center. France and Italy also are contributing instruments.
