Prevalence rate of body mass index status of over weight according to internet usage status showed that 83.1% at normal, 5.1% at potential, 11.9% at addiction. Prevalence rate of physical activity levels of 150 min/week under according to internet usage status showed that 93.8% at normal, 3.5% at potential, 2.7% at addiction. In comparison with the physical activity levels was significantly more likely potential internet usage (OR, 2.62; 95% confidence interval [95%CI], 1.09-6.47; p<.05) and addiction usage (OR, 3.82; 95% confidence interval [95%CI], 1.24-11.75; p<.05). The results revealed that physical activity levels and body mass index correlates of internet usage status. This finding suggest the necessity of developing specific strategies for physical activity intervention by internet addiction among middle school students.
『한서(漢書)ㆍ오행지(五行志)』를 통해 본 반고(班固)의 재이관(災異觀)
權珉均 ( Kwon Min Gyun ) 중국사학회 2020 中國史硏究 Vol.0 No.125
It was not until the Early Han Dynasty era that the Five Elements theory, which was popular in the Warring States Period had a complete structure and logic. Confucian scholars sought to expand their political position by emphasizing ‘Virtue [德]’ instead of honoring ‘Law[法]’. Such attempts began in earnest from the Wen-Di[文帝] period. In this social atmosphere, Dong Zhongshu[董仲舒] has begun to systematize and theoreticalize this theory. The Wu-hsing Chih[五行志] organized by the Pan-Ku[班固] includes discussions on Dong Zhongshu[董仲舒], Liu Xiang[劉向], and Liu Hsin[劉歆] about the occurrence of natural disasters caused by errors in ‘Wu-hsing[五行]’, ‘Wu-shi[五事]’, ‘Huang-ji [皇極]’. Looking at the structure, it seems that ‘control the emperor’ was not the only purpose, like the theory of Dong Zhongshu. In the ‘Wu-hsing’ stage, the government tried to restrict the behavior of officials, High-ranking officials, and out-relatives, and in the ‘Wu-shi’ stage, it is clear that it was intended to control Vassal King[諸侯王] as the will of heaven. In the Huang-ji phase, there is a calamity[災異] that could happen if emperor misled politics. Here, we can roughly guess the intention of the Pan-Ku to the emperor by writing Wu-hsing Chih.

This study of 322 elementary school children examined the interrelatedness of internet preference, frequencies of internet activities, usage of children`s popular internet sites, knowledge of internet sites, and children`s reading abilities. Usage of children`s popular internet sites and knowledge of internet sites are interrelated with decoding and comprehension. Age, knowledge of internet sites, and sex predicted children`s reading abilities. The extent of exposure to various internet activities differentiated children`s reading comprehension. Results show that processes of reading text information and multimedia materials through the internet involve not only the skills of reading traditional printed texts but also new reading strategies.
