SHENYANG, Nov. 17 (Xinhua) -- A MD-90 aircraft left the northeastern city of Shenyang for its American home on Thursday, ending the service of the last McDonnell-Douglas jet for Chinese airlines.Chinese carriers will no longer operate MD-made jets due to growing market demands, said Lu Changchun, deputy general manager with the north China branch of China Southern Airlines, which has operated the MD-90 jet for over a decade.MD-90 jets were involved in no accidents during the decade-long-service in China, so safety concerns did not lead to their retirement, Lu said, adding about 1,000 MD-90 jets are still flying around the world.Lu, however, admitted that supply of aircraft materials was affected as the production line of MD jets shrank, after McDonnell-Douglas Cooperation was merged into Boeing in 1997.MD jets were replaced mainly because Chinese airlines need new models to accommodate air travel demands fueled by the economic boom, Lu said.The north China branch of China Southern Airlines also announced Thursday the retirement of five A300-600R planes, which are replaced by A320 family jets. China Southern Airlines began flying an Airbus A380 superjumbo in China in October.China's domestic air travel market is predicted to grow 13.9 percent annually by 2014 and transport 379 million domestic air passengers, which will make the country the world's second-largest air travel market after the United States, according to a report released by the International Air Transport Association.Back in the 1990s, a Shanghai-based aircraft maker assembled two MD-90 jets in China, Lu said, adding the two jets retired this year.Change of jets model serves the strategic transformation of China Southern Airlines and meets the market demands, Lu said.Li Jiaxiang, chief of China's civil aviation administration, estimated that over 1.5 trillion yuan (235 billion U.S. dollars) will be invested in the civil aviation industry by 2015, adding about 2,000 aircraft to the country's fleet.Commercial Aircraft Corporation of China, producer of China's first self-developed jumbo jet, the C919, has announced that it will complete the design for the passenger plane in 2012. The jet is expected to take off in 2014 and put into service in 2016.

WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.

WASHINGTON, Dec. 1 (Xinhua) -- U.S. President Barack Obama announced Thursday that his administration is committing an addition 50 million U.S. dollars in funding for domestic HIV/AIDS treatment and care.Obama also set a new target of helping six million people in countries hardest hit by the HIV virus get access to life-saving antiretroviral drugs by the end of 2013, increasing the original U. S. goal by two million."We can beat this disease,"' Obama declared at a World AIDS Day event in Washington. Former Presidents George W. Bush and Bill Clinton also participated via satellite.Citing the success of the President's Emergency Plan for AIDS Relief program in providing antiretroviral treatment to people living with HIV/AIDS around the world, Obama admitted that new infections are still not going down in the United States."The rate of new infections may be going down elsewhere, but it 's not going down here in America,'' he said. "There are communities in this country being devastated still by this disease. When new infections among young, black, gay men increase by nearly 50 percent in three years, we need to do more to show them that their lives matter.''Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, also told Xinhua recently that in the United States, the AIDS epidemic has plateaued, but it is still at "unacceptably high" level.About 1.2 million Americans are living with HIV and only 28 percent of them have the infection under control, the U.S. Centers for Disease Control and Prevention reported this week."The fight is not over," Obama declared, but "the federal government can't do this alone." He called on state governments, pharmaceutical companies, and private foundations, to do their part to help Americans get access to all the life-saving treatments.Obama also appealed to global partners to step up their efforts to end AIDS, some 30 years after the epidemic first surfaced. "So on this World AIDS Day, here's my message to everyone out there. To the global community -- join us," he said.

BEIJING, Dec. 18 (Xinhua) -- China's economic diplomacy will face growing challenges in the form of trade and exchange rate disputes, as well as the task of protecting overseas investment interests, over the next few years, experts said on Sunday.Next year will be an election year for the Unite States and France, and there is an increasing possibility for the two countries to use the "China threat" as an excuse for not dealing with their own economic issues, which will put Chinese diplomacy under pressure, said Ding Yifan, deputy director of the Institute of World Development of the Development Research Center of the State Council at a seminar on Chinese diplomacy.During the first half of 2012, several countries will remain in a grave debt crisis and may even see their crises deepen, Ding said, adding that this situation may create friction between China, the United States and Europe.Additionally, protecting China's growing overseas investments will pose new challenges for the country's diplomacy, Ding said.Chen Fengying, director of the Institute of World Economic Studies under the China Institutes of Contemporary International Relations, agreed that the protection of China's overseas investment interests will be an important task for Chinese diplomacy.During the past three decades, China has invested in more than 170 countries and regions, with outbound direct foreign investment topping 170 billion U.S. dollars.In the past 30 years, China has been focused on "bringing in" foreign investment; it may do more to facilitate its "going out" in the future, Chen said.Chinese economic diplomacy will serve the country's economic construction and the protection of its overseas interests, national interests and security, Chen said, adding that China's position in the world is closely related to its economic diplomacy.Chen said China has made several achievements in international economic governance, reflected by China's growing influence in the international arena and the posts held by Chinese officials in important international organizations.

BRATISLAVA, Dec. 22 (Xinhua) -- The Slovak Education Ministry on Thursday launched an internet website to provide the general public with digitalized textbooks.According to Education Minister Eugen Jurzyca, the public could access a total of 26 digitalised textbooks, compulsory-reading books and download 65 audio-recordings on the website of eaktovka.sk.The word aktovka means schoolbag in Slovak."We hope that pupils will be able to study even in places where they don't bring their textbooks, such as during the holidays at their grandma's, but also that teachers will have an easier time putting together various textbooks or their sections on, for example, physics or chemistry," said the minister.Jurzyca said he estimated that 92 percent of households with school-age children which own personal computers and 70 percent of those which have access to the internet would visit the website.
