Objectives : To evaluate the degree of adolescent internet addiction, and investigate its relationship to the general characteristics, internet environments, and contents, especially the stress measured by the psychosocial wellbeing index-short form(PWI-SF). Methods : The data was obtained from self-administered questionnaires from 886 11th grade urban area students. The questionnaires consisted of general characteristics, internet user's environments, frequencies by internet contents, internet addiction test and PWI-SF. Results : The possible rate of internet use at home was 95.1%, and the area of most internet use was the home. The frequencies of internet game and porno site use were higher in males, with web searching and community uses higher in females. The total mean of internet addiction score was 56.8, and was higher for male than for female students. From multiple regression, as analyzed by the internet addiction score as a dependent variable, on-line friends, internet use times, years of internet use, frequencies of internet game, & porno site use, and PWI-SF scores were significant in male. Internet use times, the frequencies of internet game, chatting, community use, and PWI-SF score were significant in female. Four PWI-SF subscales(social role & self reliability, depression, general health & vitality, and sleep disturbance & anxiety) and internet addiction were significantly correlated in both male and female students, with depression having the most correlation. Conclusion : The results of this study suggest that intervention should be provided to prevent internal addiction, especially for coping with stress in Korean teenage students.

Objectives: To identify the relationship between the internet addition of elementary school students, and their health behavior and VDT syndrome, and thereby to detect the impact of internet addiction on the health behavior of elementary school students, to get the basic information necessary to develop a prevention program for internet addiction and to plan for VDT syndrome prevention program. Methods: We conducted this study during the period from jun 27, 2007 through July 8, 2007. The subjects of this study were 416 children whose grades were in 4th through 6th grades of elementary schools located in the city A in Kyung Pook Providence. Data were obtained from self-rating questionnaires. The questionnaires were composed of Korean Internet Addiction Self-examination on Internet Use Patterns (K-scale), Health Behavior Profile, VDT Syndrome, and general characteristics. We used t-test, AVOVA with Ducan method for Post-hoc comparison in means comparison between groups, $X^2$-test for frequency analysis and Pearson's correlation coefficient. We used SPSS/PC(12.0 ver) program and the LISREL 8.53 Win program for covariance structural analysis. Results: Major results were as follows. 1. The internet addiction propensity distribution based on the distribution of scores were investigated according to the self diagnosis scale on internet addiction. 6.5% of them were high risk user group, 14.4% were potential risk users and 79.1% of them were common user groups. 2. Internet addictions by sex, internet use duration, frequency (days/week), time(hours/day), purpose, position, brightness of internet, attitude of parents and frequency of conversation of family members were statistically significant(p<0.01). 3. There was a statistically significant difference in VDT syndrome according to internet addiction groups(p<0.001) besides ocular symptoms, dry mouth and GI troubles. 4. The health behavior score was the lowest in high risk user group(p<0.001). There were significant differences between internet addiction groups in personal hygiene and habits of daily living(p<.002), the prevention of accidents(p<.002), the practice concerned with the prevention of infectious disease(p=.002), and mental health(p<.001). 5. There was also a significant negative correlation between internal addiction and health profile(r=-0.365, p<0.01) and a significant positive correlation between internal addiction and VDT syndrome(r=0.331, p<0.01). 6. As the result of structural model analysis, internet use time(/day), days of internet use(/1week), conversation frequency among family members, degree of brightness of internet use had significant direct effects on internet addiction. Conclusions: The results will help the development of an effective intervention program for the prevention and treatment of internal addiction by clarifying the effect of the internal addiction upon elementary school students' VDT syndrome and health behavior.

Objectives: Studies investigating problematic internet use have increased rapidly and have been focused on its causes, psychopathology, prevalence, characteristics and so on. However, there are few studies concerning the correlation between problematic internet use and youth health risk behavior. Therefore, the purpose of this study was to examine the relationship between problematic internet use and youth health risk behavior. Methods: A community sample of 632 high school students in grades 10 and 11 was collected for the survey. The sample was assessed using the Youth Risk Behavior Surveillance System(YRBSS) and Young's Diagnostic Questionnaire of Internet Addiction(YDQ). The subjects were classified into two groups: normal and problematic internet use, and the problematic internet use group was further divided into at-risk use and addiction groups. Results: There were 56 subjects(8.9%) in the internet addiction group and 56 subjects(8.9%) in the at-risk internet use group. The other 507 subjects were classified as normal. The subjects in the internet addiction group kissed more frequently and ate less fruit than those in the normal group. They also showed a relatively higher tendency to watch TV, ride in a car driven by a drunk driver and to carry a weapon than those in the normal group. There were no differences in health risk behaviors between the subjects in the internet addiction group and those in the at-risk internet use group, except for the possibility of riding in a car driven by a drunk driver. Conclusion: Unlike the normal group, there was very little difference in health risk behavior between the internet addiction group and the at-risk internet use group, which indicates that the addiction group and the at-risk internet use groups are homogenous. It is important to focus on the behavior of individuals in the at-risk group, and preventive measures should be taken in order to reduce the possibility of at-risk adolescents becoming addicted.

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.

This paper analyzes the effect of network neutrality regulation on social welfare using the two-sided market under the network congestion. This paper deals with zero price rule regulation which means the price regulation on the side of content. The results are as follows : First, under the monopoly platform, internet use price, contents price, and the number of internet user and content provider are all decreasing as the network congestion increases. Second, under the monopoly platform internet use price, contents price, and the number of internet user and content provider are all increasing as the network capacity increases. Third, the price of internet use and contents internet use which maximize social welfare are increasing and the number of internet user and content provider are decreasing as the network congestion increases. Fourth, optimal network capacity for monopoly platform provider is less than socially optimal network capacity. Fifth, if network neutrality regulation is enforced, the price of internet use is higher than monopoly platform provider and the price of contents is lower than monopoly platform provider. Also, the number of internet user is less than monopoly platform provider and the number of content provider is more than that. By the way, when network congestion increases, internet use price, the number of internet user, and the number of content provider are decreasing. Sixth, network neutrality regulation is more effective for internet user side than contents provider when network congestion is considered. This means that network neutrality regulation is not effective for contents market side when network congestion is seriously large.

Purpose: The purpose of this study was to investigate the patterns of internet usage, selfefficacy, and self-esteem of the elderly. Method: Study participants were 139 older than 60 years of age who had used internet and could access internet anytime at home. Data were collected from March to September, 2009 by using a structured questionnaire. The data were analyzed using PASW/WIN 18.0 program. Results: The meantime of internet use was 8.74 hours per week, frequently used web-site was 'Newspaper and magazine', and subjects mainly used internet 'not to fall behind the times'. The mean score of internet use capability was 2.42, among theses the score of 'Searching necessary information' was the highest. The internet use capability of the subjects was significantly different in terms of education level, spouse, economic status, and the length of use. The mean scores of self-efficacy and self-esteem were $28.22{\pm}4.42$ and $28.51{\pm}4.25$, respectively. Conclusions: These results suggest that the elderly people use internet not to fall behind the times but they have enough capability to use internet searching or e-mailing. Also, it is true that there are many influencing factors on internet use and capability of the elderly. Therefore, it is needed to investigate the internet use of the elderly more closely.

The purpose of this study is to investigate the impact of the Internet channel introduction on the channel composed of a monopoly manufacturer and an independent physical retailer. This study also examines what would be the best strategy for the Independent physical retailer to respond to the new internet channel entry. The game theoretic model consists of a monopolist manufacturer selling its product through a channel system including one independent physical store before the entry of an internet store. The audition of the internet store to this channel system results in a mixed channel comprised of two different types of channels. The new internet store is launched by the manufacturer. The results show that an Internet channel entry has the following impacts on the existing channel members. First, the manufacturer's internet channel introduction mitigates the double marginalization problem of the traditional channel. Second, the manufacturer could enhance Its channel power by introducing its own internet channel while it diminishes that of the incumbent independent physical retailer. Third, manufacturer's adding a new internet store leads to a higher demand. Finally, with its own internet direct channel, the manufacturer has an opportunity to practice price discrimination. The manufacture leaves only those with a strong preference for the physical store to be served by the Independent physical store. The results suggest that the independent physical store's best strategy to the entry of the manufacturer's Internet channel is to focus on the consumers who are highly loyal to the physical store while maintaining a high retail price.

오늘날 디지털 기술의 발달로 인터넷이 대중화되었고, 인테넷 이용자가 증가함에 따라 인터넷을 이용한 광고가 증가하고 있다. 특히 인터넷을 이용한 광고는 시간에 관계없이 고객과 기업이 쌍방향(interactive) 커뮤니케이션이 가능하여, 제품의 특성이나 회사에 대한 이미지를 고객에게 능동적이고 효과적으로 제공할 수 있다는 특징을 가지고 있다. 이렇게 인터넷 광고는 시간에 상관없이 불특정 다수 인터넷 접속자에게 시선을 끌 수 있다는 주목도(Attention)와 쌍방향 커뮤니케이션이 가능하다는 매력(Charming)이 있어서, 인터넷 이용자가 보다 더 손쉽게 참여(Easy to Participation)를 할 수 있다. 현재 인터넷 광고의 주를 이루는 베너광고나 그 외의 광고는 인터넷 유저와 상호작용이 활발하지 못하다. 게임의 가장 중요한 요소가 상호작용이라는 점을 인터넷 광고에 이용한다면 더욱 효율적인 광고가 될 수 있다. 이러한 점에 착안하여 본 연구자는 인터넷 광고의 특성과 게임의 상호작용성을 토대로 하여 게임 성향의 인터넷 광고의 실제 디자인 프로세스 사례를 제시하고자 한다.
