'타진요' 사건이나 최진실의 자살사건 등에서 보듯이 인터넷상의 명예훼손은 치명적인 결과를 수반한다. 온라인상의 명예훼손은 연예인이나 공인을 넘어서 일반인에 까지 확산되고 있다. 온라인 포럼과 소셜네트워크의 범람은 인터넷 명예훼손의 피해자들에 대한 체계적인 보호 장치가 절실함을 반증한다. 그동안 우리나라는 미국의 유사한 해당 법률과 정책을 기반으로 "정보통신망이용촉진및정보보호등에관한법률" 등을 통해 네티즌과 인터넷 서비스 제공자간의 법적인 책임에 대한 범위를 규정함으로써 인터넷 명예훼손을 방지하려는 시도를 해왔다. 그러나 내용의 진위여부와 관계없이 인터넷 명예훼손의 피해자들은 제대로 된 보상도 받지 못한 채 낙인으로부터 자유하지 못한 것이 현실이다. 따라서 본 연구는 우리의 인터넷 명예훼손 방지 법안의 근간이 된 미국의 "통신품위법"과 최근 메릴랜드주 항소법원의 판례인 Brodie 사건을 고찰함으로써, 우리의 인터넷 명예훼손 방지 정책이 나아가야 할 실질적인 방향을 분석하고자 한다.

Objectives : To develop measurement scales of Internet addiction, and propose a Korean Internet Addiction Index (K-IAI) and classification criteria for Internet addiction from the threshold scores developed. Methods : The identification of the concept of 'Internet addiction' was based on the literature review. To select the scales, an exploratory factor analysis was applied. A construct validation was tested by a confirmatory factor analysis (CFA) with a structured equation model (SEM). In testing the validity of the classification criteria, ANOVA and non-recursive models with SEM were applied. Results : Out of 1,080 questionnaires distributed, 1,037 were returned,; a response rate of 96%. The Cronbach-$\alpha$ of all items was over 0.75. Using an exploratory factor analysis in the condition of a 6 factor constrain as the study model proposed, 23 of the initial 28 items were identified. In testing the discriminant and convergent validity of the selected 23 scales using CFA with SEM, the Internet addiction model explained about 93% of all variances of the data collected, and all the latent variables significantly explained the designated scales. A K-IAI was proposed using the T-scores of the sum of all factor averages. In the classification of users, the basic concept was a twostandard deviation approach of the K-IAI as the criteria of MMPI. The addiction group had a score ${\geq}70$ in the K-IAI, the pre-addiction group between ${\geq}50$ and <70, and the average user group <50. The Internet use times of the classified groups were statistically different in the ANOVA and multiple comparisons. Conclusions : The K-IAI is a reliable and valid instrument for measuring Internet addiction. Moreover, the taxonomy of the groups was also verified using various methods.

Purpose: The purpose of this study was to investigate the relationship between the risk of school bullying victimization and the risk of Internet gaming disorder according to gender in adolescents. Methods: The data of 1,920 middle school students collected at the baseline of the Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence (iCURE) study were analyzed. For statistical analysis, $x^2$ test, t-test and stratified multiple logistic regression analysis were conducted using SAS 9.4. Results: The prevalence rate of Internet gaming disorder of middle school boys was greater than that of girls (Boys: 9.9%, Girls: 6.2%). The greater the risk of school bullying victimization, the greater both the risk of Internet gaming disorder and the average daily time spent on Internet gaming. In girls, the relationship between the experience of being bullied in school and Internet gaming disorder was not statistically significant. However, the boys who had been bullied in school were 3.2 times more vulnerable to the risk of Internet gaming disorder than those without such experience (95% CI: 1.135-8.779). Conclusions: When considering interventions for Internet gaming disorder for adolescents, bullying victimization should be taken into account as well. Particularly, relieving stress related to bullying victimization can be important for boys with Internet gaming disorder.

This study was carried out to investigate the utilization status of internet dietary information by gender(boys: 363, girls: 366) in adolescent(middle & high school students). The results were summarized as follows. The internet using frequency of 6-7times per week had 45.0% of subjects and the using time of internet per a time was shown mainly'<2hours(68.5%)'. The main place for internet use was home(79.0%) and favorite search engine was 'Yahoo'(45.7%) and 'Daum'(19.3%). As main purpose using internet were mentioned 'social intercourse'(45.0%) and data search'(24.8%). The organization that offer to reliable internet information was educational institution'(49.4%). The problems in using information site were 'poor information'(26.4%), 'slow connection speed'(22.6%), and 'don't arouse interest'(18.8%). The search experience about dietary information had only 27.9% of subjects and search purpose was 'for homework'(33.3%) and 'for health'(32.0). The satisfaction degree of dietary information was not high. The connection motive to dietary information was mainly 'by site navigation casualty'(55.7%). Only 7.7% of subjects had experience of nutrition counseling using internet, and the motive of nutrition counseling was also 'by site navigation causally'(55.8%). The purpose of counseling was 'for diet'(41.5%) and 'for health problem'(30.2%), and the satisfaction degree of counseling result was very low. As the ask of improvement for counseling site were pointed out 'poor in answer content'(44.8%) and 'lazy answer'(31.0%). The subjects wanted to get the dietary information about 'growth in status'(41.4%), 'diet related skin beauty'(14.6%), the update period less 1 month, and the way of 'free board'(32.3%), 'game'(21.1%) and 'animation'(19.3%) as offer tool. The results of this study showed that although the internet using percent and frequency of subjects was high, they used dietary information very seldom and they are dissatisfied with internet nutritional information. Therefore, the information donor should consider which dietary information was needed and what is the optimal tool for adolescent.

Objectives : Internet addiction or pathologic internet use is one of the major mental health problems in children and adolescents in Korea. Internet addiction is defined as uncontrollable, markedly time-consuming internet use, which lasts for a period of at least six months. Internet addiction results in poor academic performance and negative parent-child relationships. By using $^{18}F$-fluorodeoxyglucose-positron emission tomography (FDG-PET), we investigated the effects of internet addiction on functional changes occurring in the adolescent brain. Methods : Adolescent patients with an internet addiction (4 boys and 2 girls; $15.6{\pm}1.2$ years) participated in this study. Eight healthy young adults (5 males and 3 females; 18-30 years old) with no previous history of psychiatric illness also participated as normal controls. Brain FDG-PET data was obtained with the participants in the resting condition and with no addictive stimuli. Results : Statistic parametric mapping analysis of the brain FDG-PET data revealed hypometabolic changes in the visual information processing circuits and hypermetabolic changes in the prefrontal areas in the adolescents with internet addiction, as compared with normal controls (p<.001). Conclusion : These results suggest a neuronal adaptation to excessive visual stimulation and synaptic plasticity due to internet addiction.

While internet and cellular phones are very attractive to adolescents, they cause a lot of problems because of adolescent's addiction to internet and cellular phones. The purpose of this study is to investigate relations among overuse of internet and cellular phone and academic achievement with middle school students according to their sex and grade. For this purpose, the survey consist of 44-item, self-administered paper-and-pencil questionnaire from 444 two middle schools students located in Busan. Also, their academic achievements were used for statistical data processing. As a result, firstly, middle school students did not tend to be so seriously addicted to the internet and cellular phones. The internet was used more by male students and cellular phones by female students, and the more male and female students used the internet, the higher they tended to use the cellular phones. There was a negative correlation between the tendency of internet use and academic achievement, but there were no significant differences between genders. In terms of the tendency of using cellular phones and academic achievement, there were no correlations among male students, but there was a negative correlation in female counterparts. Secondly, in terms of grade, the 2nd-grade students had a higher tendency to use both of them than the 1st- and 3rd-grade counterparts. The tendency of using the internet and cellular phones, in each grade had significantly static correlation and the higher they tended to use the internet, the lower they had academic achievement the 3rd-grade. On the other hand, the tendency of using cellular phones, only 2nd-grade students had low academic achievement.
