This study aimed to identify binge-eating behavior and food addiction in Korean population and to determine their associations with obesity, eating behaviors, mental health and cognitive characteristics. We collected clinical questionnaire scores related to eating problems (e.g. binge eating, food addiction, food cravings), mental health (e.g. depression), and cognitive functions (e.g. impulsivity, emotion regulation) in 257 Korean adults in the normal and the obese weight ranges. Binge-eating and food addiction were most frequent in obese women (binge-eating: 46.6%, food addiction: 29.3%) when we divided the participants into 4 groups depending on gender and obesity status. The independence test using the data with propensity score matching confirmed that binge-eating and food addiction were more prevalent in obese individuals. Finally, we constructed the logistic regression models using forward selection method to evaluate the influence of various clinical questionnaire scores on binge-eating and food addiction respectively. Binge-eating was significantly associated with the clinical scales of eating disorders, food craving, state anxiety, and emotion regulation (cognitive reappraisal) as well as food addiction. Food addiction demonstrated the significant effect of food craving, binge-eating, the interaction of obesity and age, and years of education. In conclusion, we found that binge-eating and food addiction are much more frequent in females and obese individuals. Both binge-eating and food addiction commonly involved eating problems (e.g. food craving), but there was difference in mental health and cognitive risk factors. Therefore, it is required to distinguish food addiction from binge-eating and investigate intrinsic and environmental risk factors for each pathology.

This study deals with exploring qualitative steps and paths that appear as YouTube users' usage time increases quantitatively. For the study, I applied theories from psychology and neuroscience, subdivided the interval between the personalization algorithm of the recommendation system, and active use and analyzed the relationship between variables in this process. According to the theory behavioral model theory (FBM), variable reward, and dopamine addiction were applied. Personalization algorithms easy clicks as triggers according to associated content presentation functions in behavioral model theory (FBM). Variable rewards increase motivational effectiveness with unpredictability of the content you search, and dopamine nation is summarized as stimulating the dopaminergic nerve to continuously and actively consume content. This study is expected to make an academic and practical contribution in that it divides the purpose of use of content in the personalization algorithm and active use section into four stages from a psychological perspective: first use, reuse, continuous use, and active use, and analyzes the path.

Online games are not only tools for enjoyment, they are also the linking pins connecting between the online and the offline worlds. The effects affecting other domains can be termed 'spillover'. With the process behaving as forward and reverse spillovers, there are interaction effects on online and offline behavior. However, there is little research dealing with the spillover effects from the offline to the online domain. This study concentrates on the individual behavior of online garners centering on offline dependence. With the purpose of finding the factors affecting both flow and immersion, I am interested in the moderator effect of offline dependence influencing both flow and immersion from social interaction. A research model is developed and a survey research is conducted from one of universities in Korea. The results show that flow is strongly influenced by skills, challenge, and social interaction, but immersion is only influenced by skills and social interaction and not challenge. The findings reveal that the moderating effect of offline dependence affects only the relationship from social interaction to the immersion on the lower offline dependence group.

The objective of this study proposes the new user's addiction model in 'Social Network Games' (SNGs). Research model is derived from the separation of two characteristics. First one is logical characteristics that includes 'Functional' (F), 'Keystroke' (K), and 'Goal' (G). Second one is feeling characteristics that consists a few factors such as 'Emotion' (E), 'Social' (S), and 'Affection' (A). For the pre-test, a total of 30 participants responded to survey in order to inspect the fitness of research questionnaire, roughly validity of the proposed model, and the direction of this reseach. After that for the main test, a total 300 users participated in this research. The final number of effective participants were 261 because 39 were insincere respondents and without playing SNGs who were excluded. Then we examined the measurement model by performing 'Partial Least Squares - Structural Equation Modeling' (PLS-SEM) analysis to test the research hypothesis empirically. The results of the measurement and structural model test lend support to the proposed research model by providing a good fit to the construct data. Interestingly, the model showed the significant effects of the interaction between eleven hypothesis(H1,H2,H3,H4,H5,H6,H7,H8,H9,H10, H12). Only one hypothesis decision t-value not supported that is involved the relationship between SNGs Addiction and Keystroke, H11(1.193). This research expect to contributes to an exploratory SNGs research to clarify the base of addition and will aids understanding of users' behavior associated with SNGs development.

This study investigates the problems resulting from the Internet addiction policy management in South Korea and discusses a direction for rational policies by developing a system that facilitates interactive discussions among interest individuals and groups. The Korean society has experienced conflicts of interests among the government, the private sector and civil society in the policy. In addition, heightened competition among government ministries has led the Internet addiction policy management to be susceptible to how citizens respond to the claims of interested parties, thereby having the rationality of the policy management less count. To address these issues, this study investigates the current Internet addiction policy and explores the potential of new governance from a perspective of new institutionalism. This study suggests that the system of the Internet addiction policy should be restructured to transfer control over the policy from the central to local government and develop governance centered on the consensus of the government, the private sector, and civil society.

This study verified the relationship between internet use, family relationship, and cyber violence victimization by comparing models. 2013 The survey of Internet addiction of National Information Society Agency was used in this study to verify relationship between variables. We compared the model which internet use impact cyber violence victimization through mediating fully family relationship and other model which internet use influence cyber violence victimization through mediating partially family relationship. Based on final model (model 1), More internet use was related to lower family bond and lower family bond was associated with more cyber violence victimization. This results imply that family relationship have an important role in relationship between internet use and cyber violence victimization rather than internet use impact directly cyber violence victimization.

In this paper, we refer to positive effect and negative effect of game. And we inquire the recent trend of edutainment that emphasizes charm of game and educational effect at the same time. Because the simulation game and the role-playing game have strong toxication, the limitation of computer use is essential. Therefore, we present dynamic computer using-time control system for prevention of game toxicaton and for activity of educational contents. The method considered in this paper increases computer using-time n proportion to using of educational contents. So it lead user of computer to use educational contents voluntarily.
