This study aimed at understanding motivations and effects of online game playing of adolescents related to quality of life. The field survey was administered to 836 $4^{th}-12^{th}$ grade students in their classrooms. Findings showed that the 5 critical motivations for playing online games were : attraction to the game characters, entertainment, avoidance, loneliness, and killing-time. Motivations differed by sex and grade in school. Quality of life was related to the motivations for online game playing and to the feelings of satisfaction obtained after playing online games. Implications of these findings were discussed from the perspective of policy for the information welfare of adolescents.

This study aims to look at overall adolescents' and college students' perceptions of library and explore the sources and their related variables as well as find out related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine so much over library as their information search tool even if they trust library information sources more, also, they tend to seek information sources when it has easiness and fastness to get. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources-have significant differences each other.

This study aims to look at overall adolescents' perceptions of library and reveal the relevance of search engine sources and library sources compared each elements of them and find out any related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine over library as their information search tool, and they used library as primarily a source of information for printed materials such as books and most of them don't use the library often. Also the result shows the population users tend to select information when it is easy to get and fast to access. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources- have significant differences each other.

This paper determines if mandated alcohol health information labelling could be an obstacle to international trade by discussing international trade rules affecting member nations. WTO members could use alcohol labelling rules to protect human health, reduce the consumption of alcohol and provide product information. When a member uses alcohol labelling as a technical regulation or standard, it should comply with TBT Articles 2.2 and 2.4. If a member uses some specific warning messages for their objectives, it should be considered the contribution of the measure, trade restrictiveness, and alternatives. If WTO members want to employ their own alcohol labelling schemes for addressing carcinogenicity, intoxicating effects, dependence potential, effects on children, adolescents and pregnancy, it could be a technical barrier and also create adverse effects on international trade. Therefore, the harms of alcohol are supported by scientific evidence, and for this reason, the international harmonization for alcohol labelling should be discussed openly to prevent negative effects on trade.

Internet overdependence has become a public health concern in Korea. It is well known that family and community level efforts could alleviate possible harms from Internet use. However, little research exists regarding smartphone overdependence. This study examines factors affecting smartphone overdependence and, specifically, help-seeking for smartphone overdependence among Korean adolescents. The study is based on parental mediation theory and uses a help-seeking framework. The results indicate that preventative education provided by school and community increases the levels of awareness of both the possible harms from smartphone use and the option of accessing the mental health service, while it was not effective in preventing smartphone overdependence. Parental mediation was a protective factor for smartphone overdependence but was negatively associated with the intention to use the mental health service. In sum, behavioral problems related to smartphone use require multidimensional preventative efforts from both the family and the community. It is suggested that effective preventive education methods are developed for parents and adolescents.

This study aims to identify the relationship between outcome expectancy and illegal use of music sources, and examined the parallel double mediating model of reward sensitivity and social dilution of responsibility on that relationship. To achieve the purpose this study, data were collected from 302 male and female high school students living in Seoul metropolitan area, and a double mediating effect was analysed with PROCESS Macro 3.5 Model 4. Results indicated that outcome expectancy was positively correlated with reward sensitivity, social dilution of responsibility, and illegal use of music sources of high school students, whereas reward sensitivity and social dilution of responsibility were positively correlated with illegal use of music sources. This study found that reward sensitivity and social dilution of responsibility were mediating outcome expectancy and illegal use of music sources in parallel. These findings suggest that psychological mechanisms lead adolescents use illegal music sources might be important, and provide useful information for making strategies to prevent adolescents' uses of illegal music sources.

The purpose of this paper is to explore the factors causing adolescents' habitual use of text-based online social interaction (TOSI). The authors of the present study assumed that adolescents' perceived intimacy would affect the use of TOSI. Using structural equation modeling, the influences of perceived social presence and Internet self-efficacy on habitual use of TOSI were examined indirectly as well as directly, with and without intimacy as a mediate factor. The results show that the indirect effects were proven to be stronger compared with the direct effects. Perceived intimacy appeared to encourage more frequent uses of TOSI. The effects of intimacy were even more stronger especially with those who had higher levels of Internet self-efficacy.

This study was conducted to compare body shape satisfaction, body image perception, weight control status, and dietary habits of Korean and Chinese female high school students in order to provide information for proper body image perception of adolescents. 221 students in Yongin, a city in Korea, and 227 students in Weihai, a city in China, were surveyed using questionnaires. Body shape satisfaction was significantly higher in Chinese students (P < 0.001) compared to Korean students. 76.2% of Korean students and 72.7% of Chinese students wanted a thinner body shape than their present body shapes. Experiences of weight control, laxative or diuretics uses, eating during weight control, and vomiting after eating were significantly higher in Korean students (P < 0.05-P < 0.001) compared to Chinese students. The score for dietary habits was significantly higher in Chinese students (P < 0.001) compared to Korean students, suggesting a more desirable dietary habit among Chinese students. Students of both countries showed a significantly positive correlation between body shape satisfaction and dietary habits, suggesting that as body shape satisfaction increases, dietary habits become more desirable. In conclusion, Korean female students showed a more distorted body image perception and had more poor dietary habits than Chinese students. Nutritional education for the establishment of normal body weight, proper body image perception, and healthy dietary habits are needed.
