Purpose: The purpose of this study was to explore the relationship between cyber leisure activity and autonomic function in high school students. Methods: The subjects of this study were 242 second graders at high school located in D city. The research design was descriptive correlation study. Data were collected from August 26 to September 17, 2010, using a cyber leisure questionnaire and heart rate variability (SA-6000, Medicore, Korea) for autonomic function. Results: Total time for the cyber leisure activity was $391.3{\pm}262.0$ (min/week). Time for internet usage and computer game was $234.5{\pm}140.1$ (min/week) and $156.8{\pm}164.3$ (min/week), respectively. There were significant positive correlation between total cyber leisure time and sympathetic activity (r=.247, $p$ <.001). Conclusion: Excessive cyber leisure activity could increase sympathetic activities in high school students. Thus, nursing intervention to reduce the total cyber leisure time will be helpful to improve their neurophysiological status.

The Internet and all of its possibilities and applications have changed individuals' lifestyles in relation to socializing, working, and how they spend their leisure time. Social networking sites (SNSs), such as Facebook or Instagram, are ideal settings for interacting with others but, unfortunately, they are also ideal settings for motivated offenders to commit cybercrimes. Thus SNS users may be more vulnerable to cybercrime. The purpose of this study is to investigate the occurrence of cybercrime victimization, specifically cyber-harassment, cyber-impersonation, and hacking. Self-report surveys collected from a sample of 147 respondents were examined using the moderated multiple regression analysis and a logistic regression analysis to determine possible relationships between SNS lifestyle exposure activities and cybercrime victimization. The results indicate moderate support for the application of lifestyle-routine activity theory (LRAT) to cybercrime victimization. Possible educational and managerial implications, as well as suggestions for future research, are discussed.

A total of 1,388 students (elementary school=337, middle school=326, high school=361, university=364, consisting of 696 male and 692 female) participated in the study. The results are as follows. First, although the vast majority of adolescents (96.9%) had a computer at home, majority of adolescents visited Internet cafe. Second, 70.3% of adolescents visited Internet cafe to play Internet games, followed by engaging in information search, chatting, and participated in cyber community. Third, on average adolescents spent 5.43 hours per week playing Internet games, with more males playing Internet games than female adolescents. As for information search, the weekly average was 2.60 hours, with university students spending more time than the other groups. As for chatting, the weekly average was 1.69 hours, with no significant differences among the groups. The weekly average of Internet use was 9.65 hours, with older groups spending more time. The weekly average use of computer was 10.91 hours, with older groups spending more time and more males using more computer than females.

This paper explored the differences in university students' e-Sports patterns(e-Sports behaviors, its meaning and personalities) based on the types of game-lifestyle. The results of this study could be summarized as follows. First, game-lifestyle was categorized into 5 groups, that is, 'game with someone', 'game alone', 'addicted to game', 'novice for game' and 'flow in game'. Second, there were remarkable differences in e-Sports behaviors, its meaning and personalities(altruism, sociality and aggression) among these 5 groups. Specifically, The group of 'addicted to game' was similar to the group of 'flow in game' in the amount of time/money for game. Moreover they were highly likely to regard e-Sports game defeat as the reflection of their self-esteem and as the tool of gaining popularity/superiority to peers. Even though these similarities, the group of 'flow in game' was inclined not to permit deviant words/deeds and to keep the good manner in the cyber space as well as the real space, while the group of 'addicted to game' was permissible wrong and aggressive behaviors in the both cyber space and real space. Third, the group of 'novice for game' was less likely to participate in e-Sports activities(playing e-Sports game and watching TV) and to be less attracted to e-Sports than other groups. Moreover they had negative perspectives on e-Sports. In specific, they regarded it as a dangerous and addictive leisure activity hindering everyday life(study, relationship with peers/family etc) and health. These results would be used to develop game/e-Sports education program
