Objectives: This study aimed to identify general characteristics of health status and health behavior of adolescents in accordance with their purposes with internet. Methods: Based on Adolescent Health Behavior Online Survey (KYRBS) in 2014, a total of 57,333 adolescents who had used internet were examined in this study. Results: Users for non-academic purposes were associated with male, low grades, low education level of parents, low income level, being apart from parents, being without any consulting partners, being with one parent families, low perceived health status, the experience suicidal ideation and negative health behavior such as alcohol and tobacco. In particular, these trends were appeared strongly by internet users for the purpose of the non-academic purposes. Male among high grades is shown to be mostly Academic internet users and they were more likely to have problems with some health behaviors such as exercise frequency and smoking. Conclusions: Target population should be internet users for only non-academic purposes to prevent internet addiction of adolescents. Internet addiction prevention program should be provided in terms of mental health and problematic behavior. Additionally, health behavior of internet over user for only academic purposes should be concerned.

The purpose of this study is the investigation of the effects of user participation, network effect, social influence, and usefulness on stickiness and continued use on Internet communities. In this research, stickiness refers to repeat visit and visit duration to an Internet community. Continued use means the willingness to continue to use an Internet community in the future. Internet community-based companies can earn money through selling the digital contents such as game, music, and avatar, advertizing on internet site, or offering an affiliate marketing. For such money making, stickiness and continued use of Internet users is much more important than the number of Internet users. We tried to answer following three questions. Fist, what is the effects of user participation on stickiness and continued use on Internet communities? Second, by what is user participation formed? Third, are network effect, social influence, and usefulness that was significant at prior research about technology acceptance model(TAM) still significant on internet communities? In this study, user participation, network effect, social influence, and usefulness are independent variables, stickiness is mediating variable, and continued use is dependent variable. Among independent variables, we are focused on user participation. User participation means that Internet user participates in the development of Internet community site (called mini-hompy or blog in Korea). User participation was studied from 1970 to 1997 at the research area of information system. But since 1997 when Internet started to spread to the public, user participation has hardly been studied. Given the importance of user participation at the success of Internet-based companies, it is very meaningful to study the research topic of user participation. To test the proposed model, we used a data set generated from the survey. The survey instrument was designed on the basis of a comprehensive literature review and interviews of experts, and was refined through several rounds of pretests, revisions, and pilot tests. The respondents of survey were the undergraduates and the graduate students who mainly used Internet communities. Data analysis was conducted using 217 respondents(response rate, 97.7 percent). We used structural equation modeling(SEM) implemented in partial least square(PLS). We chose PLS for two reason. First, our model has formative constructs. PLS uses components-based algorithm and can estimated formative constructs. Second, PLS is more appropriate when the research model is in an early stage of development. A review of the literature suggests that empirical tests of user participation is still sparse. The test of model was executed in the order of three research questions. First user participation had the direct effects on stickiness(${\beta}$=0.150, p<0.01) and continued use (${\beta}$=0.119, p<0.05). And user participation, as a partial mediation model, had a indirect effect on continued use mediated through stickiness (${\beta}$=0.007, p<0.05). Second, optional participation and prosuming participation significantly formed user participation. Optional participation, with a path magnitude as high as 0.986 (p<0.001), is a key determinant for the strength of user participation. Third, Network effect (${\beta}$=0.236, p<0.001). social influence (${\beta}$=0.135, p<0.05), and usefulness (${\beta}$=0.343, p<0.001) had directly significant impacts on stickiness. But network effect and social influence, as a full mediation model, had both indirectly significant impacts on continued use mediated through stickiness (${\beta}$=0.11, p<0.001, and ${\beta}$=0.063, p<0.05, respectively). Compared with this result, usefulness, as a partial mediation model, had a direct impact on continued use and a indirect impact on continued use mediated through stickiness. This study has three contributions. First this is the first empirical study showing that user participation is the significant driver of continued use. The researchers of information system have hardly studies user participation since late 1990s. And the researchers of marketing have studied a few lately. Second, this study enhanced the understanding of user participation. Up to recently, user participation has been studied from the bipolar viewpoint of participation v.s non-participation. Also, even the study on participation has been studied from the point of limited optional participation. But, this study proved the existence of prosuming participation to design and produce products or services, besides optional participation. And this study empirically proved that optional participation and prosuming participation were the key determinant for user participation. Third, our study compliments traditional studies of TAM. According prior literature about of TAM, the constructs of network effect, social influence, and usefulness had effects on the technology adoption. This study proved that these constructs still are significant on Internet communities.

We are going to make clear three things through the examination of the subject of this study. The first thing is to verify whether perceived usefulness and ease of use of usage have positive effects on trust and satisfaction which determine the loyalty of a shopping mall. The second Is to find out the effect of perceived usefulness and ease of use of using internet shopping mall on shopping mall's loyalty through variable intermediation of trust and satisfaction. The third is to emphasize the importance of perceived usefulness and ease of use of using a shopping mall web sites and carrying out a through analyzing path that usefulness and ease of use are intermediated by trust and satisfaction to loyalty. We made a poll to people who had ever used internet shopping mall and got Information. The results are below. The easer internet shopping mail users feel when using shopping mall sites, the more they feel them useful. Perceived usefulness and ease of use of usage have positive effects on trust and satisfaction which are major preceding factors of Internet shopping mall loyalty. The perceived ease of use, trust, and satisfaction intermediate between the perceived ease of use and shopping mall's loyally while users are accepting internet shopping mali. And trust and satisfaction intermediate between the perceived usefulness and shopping mall's loyalty. These results show that the degree of usefulness and feeling easiness in using shopping mall of users should be considered seriously. The only easiness of shopping mall doesn't create shopping mail's loyalty, but, It's created when users acknowledge the usefulness, trust, and satisfy.

The purpose of this study is to investigate the effect of parenting behavior and parent-child communication on internet use among school-aged children. The subjects were 215 children whose grade are 3rd and 5th selected from an elementary school in Incheon. The statistics used for this data were t-test, one-way ANOVA(Duncan's test), and stepwise regression. The findings from the present study suggested that academic achievement and birth order turned out to be significant variables on children's internet use, except for sex and grade. Results of the stepwise regression analyses that the etiologic model of this study was more proper, and parenting behavior is more effective variable than parent-child communication in predicting internet use among school-aged children. Implications based on this study are as follows; In order to decrease the degree of school-aged children's internet use, parents should do less permissive parenting behavior and problematic communication with their children.

Purpose - This paper analyzes the economic and non-economic factors that contribute to environmental sustainability by reducing CO₂ emissions, based on G20 panel data. Design/methodology - We conduct a comparative analysis of advanced and developing economies during 1995-2016. To examine the impact, an environmental Kuznets curve (EKC) model was employed, incorporating additional explanatory variables such as internet use, renewable energy, and services trade. Findings - The empirical findings show the existence of an inverted U-shaped EKC phenomenon between GDP per capita and CO₂ emissions in G20 economies, with the turning point at a per capita GDP level of US$ 38,340. Moreover, an inverted U-shape relation exists between internet use and CO₂ emissions, with the turning point at a 44% internet use rate. The comparative analysis show that the inverted U-shape curve only exits in advanced economies, with turning points of US$ 42,356 per capita GDP and 27% internet use rate, respectively. Renewable energy and services trade have a greater negative impact on CO₂ emissions in advanced economies than in developing economies. Originality/value - Renewable energy and services trade have a greater negative impact on CO₂ emissions in advanced economies than in developing economies. Overall, the results suggest the role of internet use, renewable energy and services trade in sustainable development in G20 countries.

With recent surge of Internet use, many people become concerned with side effects of Internet. Especially Internet addiction has become a significant issue. As Internet users become much younger than before, Internet addiction is salient even among elementary school students. While much research has been conducted on adolescents' addiction, only a little research has been conducted on elementary students' Internet addiction. In addition, it is necessary to use a standardized and reliable evaluation tool that is designed to assess the level of children's and adolescents' Internet addiction. The purpose of this study is to grasp the realities of elementary students' Internet addiction using an evaluation tool developed for elementary and secondary students, and to analyze the factors affecting Internet addiction. A survey was conducted to 1,382 5th and 6th graders selected from nationwide schools. The results of this study shows that 5.5% of the sample students are in the stage of serious addiction, and 12.4% in the stage of early addiction. In addition, the degree of Internet addiction significantly differs by various variables such as demographic factors, the experience of Internet use, family-related traits, and social activities.

This study examines the effects of Internet-based English practice on listening and reading. Out of a total of 16 students who took part in pre- and post-tests, 11 who had frequently practiced listening and reading on the Internet showed greater improvement in these skills than the 5 who had practiced less. The findings also suggest that summarization of listening and reading on the Internet was useful as it made students concentrate specifically on the content. This study suggests that English language teachers use a bulletin board to complement the use of Internet sites for listening and reading practice outside of the classroom in an EFL context.
