BEIJING, Feb. 26 (Xinhua) -- China's Ministry of Education said Friday that 34.29 million students graduated from the country's higher-learning institutions between 2006 and 2010.Xu Mei, the ministry's spokeswoman, said the number is even more than that of the graduates in the 20 years prior to 2006 combined."During the 11th five-year plan period (2006-2010), higher education has become even more accessible to the general public. Higher-learning institutions provide a strong support of brain power and human resources to the social and economic development," Xu said.The "Outline of China's National Plan for Medium and Long-Term Education Reform and Development (2010-2020)," which was publicized last year, says "the strategic goals to be attained by 2020 are to basically modernize education; shape a learning society; and turn China into a country rich in human resources."

BEIJING, Feb. 8 (Xinhua) -- China respects the results of south Sudan referendum, which was announced Monday, Chinese Foreign Ministry spokesman Hong Lei said Tuesday.Hong made the remarks in a statement concerning China's view on the results of the referendum."China respects the choice of Sudan people and appreciates the unremitting efforts of both the north and the south to promote the peace process between the two sides," Hong Lei said."China hopes the two sides will continue to resolve controversial issues through dialogue and consultation in line with the principle of mutual understanding and mutual accommodation," Hong said."China expects full implementation of the Comprehensive Peace Agreement(CPA) as well as long peace and stability in Sudan."The referendum, conducted from Jan. 9 to 15, was a major condition of the CPA, which ended a two-decade civil war between the two sides.The South Sudan Referendum Commission Monday announced the final results of the referendum saying that 98.83 percent of the voters had voted for separation.

LOS ANGELES, May 1 (Xinhua) -- Middle-aged adults who sleep too less or too much may be more likely to suffer cognitive decline, a new study suggests.According to the study, less than six hours of sleep each night is considered too little and more than eight hours as too much for middle-aged adults.The study, conducted by researchers at University College London Medical School, was published May 1 in the American medical journal Sleep.The researchers conducted the study in two periods -- the 1997- 1999 period and the 2003-2004 period. The participants were asked how many hours they slept on an average week night, and were asked the same question in 2003-2004 after an average 5.4 years of follow-up.The researchers compared those who reported changes in their sleep patterns with people whose sleep duration stayed the same over the course of the study.In the follow-up, each individual was given a battery of standard tests to assess his or her memory, reasoning, vocabulary, global cognitive status and verbal fluency.The study findings show that women who slept seven hours per night had the highest score for every cognitive measure, followed by those who had six hours of sleep. For men, cognitive function was similar for those who reported sleeping six, seven or eight hours.However, less than six hours of sleep -- or more than eight hours -- were associated with lower scores."Sleep provides the body with its daily need for physiological restitution and recovery," explained Jane Ferrie, a senior research fellow in the department of epidemiology and public health at the school. "While seven hours a night appears to be optimal for the majority of human beings, many people can function perfectly well on regular sleep of less or more hours."However, since most research has focused on the effects of sleep deprivation on biological systems, it is not yet fully understood why seven hours is optimal -- or why long sleeping appears to be detrimental, Ferrie said."Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity," she added.

BEIJING, Jan. 22 (Xinhua) -- The Chinese central government in Beijing pledged Saturday that it would work to ensure smooth and safe traveling for the public as many return home to reunite with families during the Spring Festival.It is expected that some 700 million people are to travel during a 40-day Spring Festival travel period that began Wednesday, but heavy snow and icy rain, which has continued since the new year began, has disrupted traffic and cut water and power supplies to some regions in south and southwest China.The lingering freezing weather also poses great challenges to transportation and railway authorities, as they work to avoid another travel disaster, as was seen in early 2008 when unprecedented heavy snow and freezing rain inundated the south of the country, bringing traffic to a standstill at the peak holiday season.Due to this, the Ministry of Public Security announced on Saturday that it had drawn upon the experiences gained from the 2008 weather disaster, and has ordered local bureaus to begin planning precautionary measures to combat the freezing weather.It also issued orders to local departments beginning in late December to step up snow clearance and make sure expressways and key trunk lines are not closed by snow."More police will be deployed to maintain traffic order and security, and to reduce offences such as drunk driving, speeding, passenger overloading of cars and trucks, and driving while fatigued," Huang Ming, Vice Minister of Public Security, said in a press conference held in Beijing.Meanwhile, over 8,300 service stops would be established across the country in order to provide necessities such as water and medical help to drivers and migrant works returning home for the festival.China's meteorological authority forecast Saturday that snowy weather will weaken in most regions over the next three days, but the eastern areas in southwest China will continue to see more rain and snow.On Sunday, the weather forecast anticipated that moderate snow would hit some regions in Inner Mongolia, Guangxi, and Hainan, as the southwestern province of Guizhou will see more icy rain.Local authorities said nearly 10 million have been affected in Hunan after a blizzard that started Monday, which also forced the evacuation of 73,000 people. About 15 power lines were shut down and 132 roads were closed because of snow and icy rain in Guangxi.As the freezing weather makes travel on roads more difficult, railway stations are seeing surges in passenger numbers.An official with the Ministry of Railways (MOR) said nearly 4.8 million passengers took trains on Jan. 19, the first day of the travel peak season this year, up 11.9 percent compared to the corresponding day last year. The next day, over 4.9 million passengers traveled on railways, up 17.5 percent. The Nanchang railway station even saw passenger number jump 30 percent.The MOR said earlier that it would run an additional 293 pairs of trains per day during the rush period in order to meet climbing passenger demand.Further, the Vice Minister of the country's National Development and Reform Commission, the country's top economic planning body, said the ministry would work with other government departments to implement multiple measures in maintaining a stable supply of coal, electricity, oil, and gas so that residents' demands for heating and power use can be met during the festival.The traditional Chinese Spring Festival, or chun jie in Chinese, is the country's most important festival. It falls on Feb. 3 this year. Workers nationwide enjoy a seven-day holiday that ends on Feb. 8.

JAKARTA, April 27 (Xinhua) -- Marine scientists will begin conducting an ecological survey in eight locations throughout the resort island in Indonesia's Bali province that could be developed as marine managed areas due to their biodiversity and coral structure, the Jakarta Post quoted an expert as saying on Wednesday.The survey, which will take place from April 29 to May 11, will be carried out by four international scientists and local scientists from universities.Ketut Sarjana Putra, the marine program director with Conservation International Indonesia, said Tuesday the survey was aimed at identifying marine species and their population in each of the eight locations.Selected from 25 potential marine conservation zones, the eight locations are Pulaki and Pemuteran, Lovina, Les Village, Tulamben and Amed, Padangbai, Nusa Penida, Bukit Uluwatu Peninsula and Perancak Beach. "We will go around Bali, starting from Sanur in the south, heading east, then covering the northern and the western areas, then back to the south," Ketut told the daily.The survey is part of a process to build a network of marine protected areas to effectively manage the island's marine and coastal resources to sustain environmental and socioeconomic value and benefits, with priority given to the eight locations.
