【正文】 s Guangzhou city anized the Chengdu festival. A terrifying wooden bridge in China has just been replaced by a glass one. This, the world’s longest glassbottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground. The floor is made of doublelayered glass that is 24mm (), and is reportedly 。s suggestion that a special day be marked in the year for the global practice of the stressbusting regimen, which is already a multibillion dollar industry in the United States. Modi said in the speech: Yoga is an invaluable gift of India39。t conducive to raising a child. She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 years, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to bee pregnant. I conducted prehensive physical checkups. The results suggested that Xiao39。s health. Poor technique harms the muscles and skeleton, and can cause secondary injures. And, jogging in a bad environment can cause circulation problems, said Lu Zhiyong, attending doctor, Sports Hospital, General Admin. of . Lu has some tips for joggers, and those who are thinking of taking it says people sh ould first evaluate their physical condition, to decide the amount and type of exercise, and jogging in the open air is better running on a treadmill. Conrad Macao will run special programs for the entire month of October this year to support the Hong Kong Cancer Fund39。ll hold off jogging for a while. But if I really want to get away from work, I39。s work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. I e to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim, He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing39。s digitized society, will also be attached on the report.Myopia is not only a disease that makes people see things blurrily, but also leads to severeplications, such as glaua (increased pressure within the eyeball), and can causeblindness, said Zhou Yuehua, an established eye care specialist with Beijing TongrenHospital.It is very important for parents and children to know about the risk and care for their eyes.There are about 450 million myopia patients in China. Among Chinese myopia patients,30million are severe patients, according to ZhouThe prevalence of myopia among high school and college students is more than 70 percent,and the situation is continuously worsening, he Zhu, director with the China Youth Development Service Center, said long hours ofstudy, lack of exercise, especially outdoor activities, and attachment to electronic screen aresome of the top reasons behind the widespread myopia problems, and the increase ofyounger patients, although China has made great progress in improving the hardwarefacilities and lighting conditions in said he hopes the survey will alert people on the threatening situation, and also helpmedical experts to better guideline parents and children39。人臉檢測與識別技術綜述 [J]. 2021,5 [3] 高建坡，王煜堅，楊浩等．一種基于 KL 變換的橢圓模型膚色檢測方法 [J]．電子與信息學報． 2021， V01． 29， No． 7． [4] 李剛，高政、人臉自動識別方法綜述、計算機應用研究、 2021, Vol 8:49 [5] 高建坡，王煜堅，楊浩等．一種基于 KL 變換的橢圓模型膚色檢測方法 [J]．電子與信息學報． 2021， V01． 29， No． 7． [6] 高建坡．視頻序列中的人臉檢測與跟蹤算法研究．東南大學博士學位論文 ． 2021，3． [7] 基于五官特征定位的人臉識別技術在防盜門中的應用 [D]中國海洋大學： 2021 [8] Huang F J， Chen T． Tracking of multiple faces for human— puter interfaces and virtualenvironments[C]． IEEE Intl． Conf． on Multimedia and Expo． New York， July 2021． [9] 張翠平 ,蘇光大人臉識別技術綜述中國圖像圖形學報 [J]2021 年 11 期 [10] Viola P， Jones M． Rapid object detection using a boosted cascade of simple feature[c]． In： Proceedings of IEEE Conference on Computer Vision and Pattern Recognition， Kauai， Hawaii， USA， 2021， 1： I51l518 [11] Viola P.， Jones M.
