Objectives : Internet became essential component in these days. This study primarily tried to find out the characteristics of high risk internet users through using the communication scale. Methods : We investigated levels of internet addiction using Internet Addiction Scale in 1,193 high school and middle school students. Participants were divided into 3 groups (high risk user group, potential risk user group, normal user group) according to the results from internet addiction scale. We additionally surveyed characteristics of internet use, and patterns of communication and Communication Scale based on Satir theory in 614 from 1,193 participants. Results : Boys showed higher tendencies for internet addiction than girls in internet addiction scale. There were significant differences in mean computer using time especially during weekends among 3 internet user groups. The distribution of communication types in each internet user group was similar and this finding coincided with previous study results. However high risk user group showed higher scores in each inadequate communication pattern such as placating, blaming, super-reasonable and irrelevant stance. Conclusion : These results suggest that adolescents who use internet in addictive patterns may have more problematic communication styles and these may be associated with poor interpersonal relationships.

The research results are as follows: First, there appeared subordinate factors in the stress suffered by the students. These included stress from their families, from conflicts with their teachers, from the living environment, current schoolwork and future course in college, insecurity over their physical appearance, bullying from other students, and relationships with friends. Among these factors, stress caused by conflicts with teachers and family was the most frequently cited, while stress from their friends was the least cited. The motive in using the Internet was found to be bound with several factors. These include: a form of diversion, a way to communicate with others, a means in coping with loneliness, a source of news and information, a form of passing away time, a kind of habit, and others. Among these motives, passing away time and indulging a habit were cited the most, followed by news and information search, and a form of diversion. Second, as a subordinate factor in Internet addiction, the following were cited: formation of tolerance, health issues, occurrence of problems related to daily life, satisfaction or a pleasant sensation, withdrawal, cover-up on the use of the Internet, and formation of virtual interpersonal relationships, and others. Among these, the formation of tolerance came out the highest, followed by health issues, daily life, and problems related to daily life. Third, in terms of the effects of stress on the motive in using the Internet, the research found that the more the students felt stressed out by conflicts with their teachers and family, the more they tended to use the Internet to communicate with others, to cope with loneliness, to obtain newsI and information, to passawaytime, and to indulge a habit Also, the more they felt stressed out by the living environment, the more they tended to use the Internet to communicate with others, to cope with loneliness, and use news and information. The more they felt stressed out by their schoolwork and future course in college, they tended to use the Internet as a form of diversion and to secure news and information. The more they felt stressed out by their insecurity over their physical appearance and being victimized by bullies, the more they tended to use the Internet to cope with loneliness. Fourth, as for the effect of several variables on student addiction to the Internet, the study found that the more students felt stressed out by their living environment, by schoolwork and future course in college, by their physical appearance, and bullying from other students, the more they used the Internet as a form of diversion, a communication tool, and as a means of passing away time or indulging a habit. The study came up with the finding that the more the students used the computer and the Internet, the probability of their getting addicted to the Internet got higher.

Objectives: This study was performed to consider the association between Internet using time for non-educational purposes and adolescent health, and to examine how health status differs between Internet users and non-users. Methods: We analyzed 2009 data from the Korea Adolescent Risk Behavior Web-Based Survey, conducted on a nationally representative sample of students in grades 7 to 12. A total of 75 066 adolescents were categorized into four groups according to their Internet using time excluding using for educational purposes: non-Internet users (NIUs), occasional Internet users (OIUs) (<1 h/d), moderate Internet users (MIUs) (${\geq}1$ and <2 h/d), and heavy Internet users (HIUs) (${\geq}2$ h/d). Health factors included eight health risk behavior indices, four mental health indices and six physical health indices. Results: The distribution of Internet use was as follows: NIUs 17.4%, OIUs 68.1%, MIUs 12.7%, and HIUs 1.7%. In multivariate analysis, using OIUs as a reference, U- or J-shaped associations were observed for five health risk behavior indices (current smoking, current drinking, drug abuse, sexual intercourse, sedentary behavior on weekdays) and four mental health indices (stressed, depressed, suicidal ideation, attempted suicide) in both genders. After removing confounding effects, including age, region, school type, subjective school record, subjective economic status, presence of parents, living with family, and sedentary behavior, these associations were still observed. Conclusions: Health professionals should consider both Internet non-users (for non-educational purposes) and heavy users to be high-risk groups in terms of health status. Also, more well-designed studies are needed to clarify what factors are working in these nonlinear associations.

인터넷을 이용한 전화(VoIP)의 사용이 전세계적으로 확산 일로에 있으며, 이미 여러분야에서 부분적으로 실용화하여 사용되고 있다. 그러나 상대방과의 통화는 그 목적에 따라 비밀을 유지해야 할 필요가 있고 비밀이 보장되어야 한다. 일반적으로 사용되는 일반 전화망(PSTN)은 상대방과 1:1로 회선이 연결되어 도청이 상대적으로 어렵지만 인터넷 망은 무수히 많은 사람들이 동시에 접속이 가능하므로 상대방과의 통화에 있어 비밀 보장이 어렵다. 따라서 본 연구에서는 개인 통신망(VPN) 프로토콜을 SIP 프로토콜을 탑제한 인터넷 전화기(VoIP)와 접목하여 도청 방지용 인터넷 전화기의 새로운 모델을 제안하고, 일반 인터넷 전화기와 성능을 비교 분석하여 실용화의 가능성은 입증한다.
