This study examines the similarities and differences between the causes of juvenile delinquency in online and offline environments and in personal characteristics. The study utilizes data from the '2014 Survey on Juvenile Victimization in Korea'. The population of this survey is students attending middle and high schools across the country. While this paper is based on the Self-Control theory, opportunity factors based on the Routine Activity theory and the Situational Action theory are also applied. Results show that the causes of offline delinquency are low self-control, routine activity and frequent gaming and SNS use. The causes of online delinquency are high self-control, existence of communication with unknown persons and the spectrum of personal information online. The common element of offline and online delinquency was the presence of delinquent peers. These results show that while online and offline delinquency cannot be explained with the same methodology, at the same time they are not mutually exclusive.

With the continuous development of emerging technologies represented by VR technology, many game developers are declaring that they are constantly trying to break the "fourth wall" and break the boundaries between virtual and reality to create game immersion for players. new game. But for many gamers, a strong sense of immersion is not the focus of their pursuit. The sense of control and safe exploration during the game is also the game experience that many gamers are pursuing. Moreover, there is ambiguity in the definition of the concept of breaking the fourth wall in the field of academic theory. The purpose of breaking the fourth wall was to separate the real world from the virtual world, to remind the audience that the actors and the audience are in two different worlds, and to trigger the audience's thinking about drama and deeper philosophy. But in the current game, it has become a blurring of the boundary between virtual and reality, pulling players into the virtual world, and focusing on the immersive experience. In this paper, we will first sort out the concept of "breaking the fourth wall", and then conduct a comparative analysis of horizontal scroll games and VR games, and conclude that the "fourth wall" has an impact on players Great conclusion.

Objectives : This study compared covert narcissistic propensity in adolescents with internet addiction tendency to normal adolescents. Further, we investigated the correlation between such propensities and anonymity in cyberspace, presence feeling and interactivity in internet gaming, and achievement motivation in adolescents with internet addiction tendencies. Methods : Male middle school students with internet addiction tendencies (Addiction Tendency Group, N=27) and normal students (Control Group, N=29) were recruited. The scale of internet use, Covert Narcissism Scale, scale of achievement motivation, scale of anonymity in cyberspace, scale of presence feeling in internet games, and the scale of interactivity in internet games were administered. A comparison of the average scores and correlation analyses were performed. Results : 1) Compared with Control Group, the Addiction Tendency Group showed significantly higher scores on all subscales of the Covert Narcissism Scale, and both the scale of presence feeling and that of interactivity in internet games. Further, the score on the scale of achievement motivation for the Addiction Tendency Group was significantly lower than that of the Control Group. 2) In the Addiction Tendency Group, the scores on several subscales of the Covert Narcissism Scale were significantly positively correlated with the scores on the scale of presence feeling in internet games, anonymity in cyberspace, and interactivity in internet games. However, in the Control Group, the scores of several subscales on the Covert Narcissism Scale were significantly negatively correlated with the score on the scale of achievement motivation, and was significantly positively correlated with the score on the scale of interactivity in internet games. There were no other significant correlations between the scores on the subscales of the Covert Narcissism Scale and the scores of either presence feeling in internet games or anonymity in cyberspace. Conclusion : These results suggested that adolescents with a tendency to be addicted to the internet exhibited higher covert narcissistic propensities than normal adolescents and that the covert narcissistic tendencies were related with presence feeling in cyber games as well as with anonymity in cyberspace.

With the deployment of web-based educational game over the internet, the user's registration becomes a critical element. The user is authenticated by the system using username, password, and unique code. However, it cannot be handled properly because the data is transmitted through insecure channel on the network. Hence, security requirement is needed to avoid identity leakage from malicious user. In this paper, we propose a secure communication approach using SSL protocol for an online game. We also describe the security requirements for our approach. In future work, we intend to configure and implement the SSL protocol by enabling HTTPS in web-based online game.

The laws and policies governing Korea's game regulations are becoming more and more topics for debate as we enter the Age of Internet. The nature of the basis for Internet regulations and policies are not rooted in freedom of speech or fundamental values of democracy, but rather focused on solving real-world problems such as protection of the youth. Furthermore, the reality is that regulatory devices for keeping the social order such as regulating gambling are being applied directly to games without consideration on the characteristics of Internet gaming, raising concerns that the expansion of constitutional values and innovative empowerment inherent to the Internet are being weakened. The Geun-Hye Park Administration which succeeded Myung-Bak Lee's Administration, even went so far as to implement the so-called "Shutdown Policy", which prohibits access to Internet games during pre-defined time zones and also instigated a time zone selection rule. In order to curb the gambling nature of Internet games, government-led policies such as the mandatory personal identification and prohibition of player selection or in other words mandatory random player selection are being implemented. These institutions can inhibit freedom of speech, which is the basis of democracy, violate the right of equality through unreasonable discrimination between domestic and foreign service providers, and infringe upon the principles of administrative law, such as laws, due process in policies, and balance in among policies and governmental bodies. Going forward, if Korea's Internet game regulations and polices is to develop in a rational manner, regulatory frameworks will need to be designed to protect the nature of the Internet and its innovative values that enable the realization of constitutional values; for example, the Internet acting as the "catalytic media for freedom of expression as a fundamental human right ", which has already been acknowledged by the Korea's Constitutional Court. At the same time, transparent procedures should be put into place that will allow diverse participation of stakeholders including game service providers, game users, the youth and parents in the legislation and enforcement process of regulatory institutions; policies will also need to be transformed to enable not only regulatory laws but also self-regulation system to be established. And in this process, scientific and empirical analysis on the expected effects before introducing regulations and the results of enforcing regulations after being introduced will need to be strengthened.

근래에 인터넷 등의 네트워크를 통해 어떤 정보에 접근할 수 있는 다양한 클라이언트 장치들이 널리 보급되고 있다. 하지만 통신능력이나 처리 및 저장능력, 화면표시 능력 등 여러 가지 제약을 가진 클라이언트 장치들로서는 방대한 양의 멀티미디어 콘텐츠를 쉽게 처리할 수 없는 문제가 있다. 또한 네트워크 측면에서도 음성, 데이터 및 비디오의 통합 서비스는 네트워크 기술의 목표를 수정하게 되어 네트워크가 다양한 서비스의 종합 제공 능력과 각 서비스에 필요한 QoS를 제공할 수 있는 능력을 가져야 하게 되었다. 이러한 이유로 ATM망과 인터넷 사이에 중단없는 멀티미디어 서비스를 제공할 수 있는 EAGIS(Efficient ATM Gateway for real time Internet Service)를 개발하게 되었다. EAGIS는 연동장치, 콘텐츠 서버, 트랜스코딩 서버, 서비스 브로커로 구성된다. 본 논문에서는 EAGIS의 구조 설계와 트랜스코딩 서비스 제공 방식을 설계하였다. RTP(Real Time Protocol)를 이용한 양방향 통신은 RTCP(Real Time Control Protocol)의 시각-소인(time-stamp)에 의하여 트랜스코딩 시간을 설정하며, HTTP를 이용한 단방향 통신은 셀프타이며(self-timer)를 이용한다. 이러한 기준 시간을 이용함으로써 네트워크 트래픽 부하와 프레임 전송률에 의한 표준화된 트랜스코딩 방법을 적용할 수 있었다. 또한 다중 사용자 유효 대역폭 확보 알고리즘을 통한 서비스의 품질을 보장할 수 있었다.

Objectives : This study was aimed at investigating the relationship between internet game addiction and emotional and behavioral characteristics of students both in the 5th and 6th grade of elementary school and in middle school. Methods : Two elementary schools and two middle schools were chosen to participate. The students completed selfreport questionnaires designed by the authors, called the Internet Game Addiction Scale, Korean youth self-report (K-YSR). Results : Compared to previous studies, the rates of those in the obvious game addiction group were much lower in this study. We defined the upper 10% of internet game addiction scores as a high risk user group and the lower 10% as a control group. There were significant differences between the groups with respect to the the ages at which internet gaming began, the frequency of game play per week, and the average length of each game playing session. Significant associations were also found between the level of internet game addiction and the withdrawn and delinquency subscales of the K-YSR. However, the association between game addiction and the withdrawn subscale was found only in middle school students. Conclusion : The findings from this study suggested that withdrawn and delinquent behaviors could be predictors of internet game addiction. Results also suggested the importance of early childhood intervention for preventing the development of more severe psychopathology in early adolescence.

우리나라에서 대부분의 중고등학생이 인터넷으로 게임과 오락으로 여가활동하는 것으로 나타났다. 이에 본 연구는 중고등학생의 인터넷 게임사용 시간에 따라 그룹화하고 가정환경 요인과의 관계를 알아보고자 하였다. 그룹은 평균 30분미만 그룹, 30-1시간30분 그룹, 1시간30분-3시간 그룹, 4시간 이상 그룹으로 하였다. 대상자는 중고등학생 6,487명을 대상으로 하였다. 게임 속 캐릭터에 대한 생각에서는 평균 1:30~3:00시간 미만 그룹은 전혀 그렇지 않다고 응답하였으나, 평균 4:00시간 이상 그룹은 때때로 그렇다고 유의한 응답을 보였다. 게임으로 인한 숙제시간 부족에서도 평균 1:30~3:00시간 미만 그룹은 전혀 그렇지 않다고 응답하였으나, 평균 4:00시간 이상 그룹은 때때로 그렇다고 유의한 응답을 보였다. 여가만족-흥미에서도 모든 그룹이 보통이다고 가장 높은 응답을 보였다. 본 연구결과 대상자의 인터넷 게임 중독에 영향을 미치는 요인을 평일 인터넷 게임시간으로 분석한 결과 특히 인터넷 게임중독 진단과 학업성적 등과 관련된 변수에서는 평균 4:00시간 이상 그룹에서 다른 그룹과 뚜렷하게 구분되었다. 이제는 인터넷이 없는 생활은 생각하기 힘들만큼 우리 생활에서 크고 중요한 자리를 차지하게 되었으나, 또한 중요성이 증가한 만큼 인터넷에 대한 우리의 의존도도 함께 높아진 실정으로 자제력과 판단력이 미흡한 아동청소년들에게 인터넷의 적절한 활용과 올바른 사용에 대한 교육이 더욱 필요하다.

Purpose: The purpose of this study is to identify the relationship between school adjustment and stress-coping styles among adolescents. Methods: This is a descriptive correlation survey using a convenience sample of 701 middle school students in Seoul, Gyeonggi, Incheon, Jeonbuk, and Gangwon province, Korea. The study's questionnaire included a scale of school adjustment and a scale of stress-coping style. The data analysis, using the SPSS 19.0 program, involved frequency, the mean and standard deviation, the t-test, ANOVA, the scheffe test, and the Pearson correlation coefficient. Results: Positive correlations were identified between positive stress-coping styles and the adjustment to school life of adolescents. The degree of school adjustment varied significantly according to the region, grade, attending private educational institutes after school or not, academic performance, daily study hours after school, and the hours students spend on gaming and Internet use a day. With regard to the behaviors to cope with stress, teenagers with a higher sense of life-satisfaction tended to show active coping behaviors, and female students were more likely to show positive or negative coping behaviors than mystic coping behaviors. Since adolescents' stress-coping styles showed connection with their adjustment to school, it is necessary to develop stress management programs to help middle school students adjust to school life. Conclusion: Based on the study's findings, it is important to develop programs which can help students adjust to school and learn how to cope with stress positively.
