Objectives: The objective of this study was to assess the relationship between internet addiction and health behaviors & mental health among Korean adolescents. Methods: Data from the 2010 Korean Youth Risk Behavior Web-based Survey was analyzed. Using the Korean Internet Addiction Proneness Scale for Youth-Short Form: Self Report developed by the Korean National Information Society Agency in 2008, subjects were classified into 3 groups for internet addiction including general user, potential-risk group, and high-risk group. The health behaviors and mental health were compared among the groups for internet addiction by gender. Results: There was significantly higher prevalence of internet addiction including potential-risk group and high-risk group in boys(14.1%) than in girls(8.8%). There were significant odds ratios of perceived stress, perceived depression, perceived health and happiness, and satisfaction of sleeping in both genders at potential-risk group and high-risk group compared to general user for the internet addiction. The odds ratios of smoking at high risk group, alcohol drinking at potential risk group, eating breakfast at high risk group, and moderate physical activity at both risk groups among boys were significant. Among girls at both risk group, the odds ratios of smoking, alcohol drinking, and eating breakfast were significant. Conclusions: This study reveals a significant association among internet addiction, and health behaviors, and mental health in Korean adolescents.

This study analyzed the influence of smartphone addiction on adaptation to school life by using the questionnaire survey method of 431 students of radiological science in six regions. The results showed that 89.6% of students are the general user group, 6.3% the high risk group and 4.2% the potential risk group. Adaptability to school life was found to be social adaptability 3.71, righteous adaptability 3.17 and academic adaptability 2.95. Academic adaptability was 3.06 for male students and 2.79 for female students. And righteous adaptability was 3.26 for male students and 3.03 for female students. As a result, male students were more adaptable than female students in academic adaptability and righteous adaptability, which was statistically significant. And Social adaptability was 3.73 for female students and 3.68 for male students, but there was no significant difference(p<.001). Adaptability to school life by smartphone addiction level was found to be the general user group 3.19, the potential risk group 3.05 and the high risk group 2.81. The difference of righteous adaptability between the general user group and the high risk group was statistically significant. And social and academic adaptability of the general user group and the high risk group was no significant(p<.01).

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.

Recently game addiction of young people has become a social issue. Therefore, many studies, mostly surveys, have been conducted to diagnose game addiction. In this paper, we suggest how to distinguish levels of addiction based on EEG. To this end, we first classify four groups by the degrees of addiction to internet games (High-risk group, Vigilance group, Normal group, Good-user group) using CSG (Comprehensive Scale for Assessing Game Behavior) and then measure their Event Related Potential(ERP) in the Go/NoGo Task. Specifically, we measure the signals of P300, N400 and N200 from the channels of the NoGo stimulus and Go stimulus. In addition, we extract distinct features from the discrete wavelet transform of the EEG signal and use these features to distinguish the degrees of addiction to internet games. The experiments in this study show that High-risk and Vigilance group exhibit lower Go-N200 amplitude of Fz channel than Normal and Good-user groups. In Go-P300 and NoGo-P300 of Fz channel, High-risk and Vigilance groups exhibit higher amplitude than Normal and Good-user group. In Go-N400 and NoGo-N400 of Pz channel, High-risk and Vigilance group exhibit lower amplitude than Normal and Good-user group. The test after the learning study of the extracted characteristics of each frequency band from the EEG signal showed 85% classification accuracy.

Purpose: The purpose was to identify the risk of drug use by adolescents. Method: The participants were 933 male students in the first grade of a high school in D city. The data were collected from Aug. 5th to Oct. 30th, 2004. The instrument was the High Risk Group Adolescent Drug User Screening Test(HIRIGADUST) developed by the Korea Adolescent Society(1996). The data were analyzed using SPSS. Results: For substance use, 64.5% of the students answered that they had drunk, 40.3% that they had smoked, and 2.0% that they had tried drug use. For scores on HIRIGADUST regarding socio-demographic characteristics, there were significant differences depending on school type, personality, academic performance, economic status, and ability to talk with parents. For scores on HIRIGADUST regarding drug using-related characteristics, there were significant differences depending on drinking experience, frequency of drinking, amount of alcohol intake, smoking experience and number of cigarettes smoked. Of the students 27.2% students were in the high risk group. Conclusion: In schools, systematic and intensive assessment of drug use should be done, and if needed, a service system connected to clinics specializing in drug addiction should be established. Prevention education should be carried out continuously.

본 연구는 우리나라 청소년들 중 음주, 흡연, 본드흡입 등을 위주로 한 약물사용 청소년들에게 특징적으로 나타나는 변인들이 무엇인지를 밝히고, 이러한 변인들과 청소년의 약물사용과의 관계는 어떻게 설명되어질 수 있는지를 고찰해 보고자 하였다 서울지역 고등학교 1, 2학년에 재학중인 남자 465명과 여자 433명, 총 898명을 대상으로 자종 약물의 사용여부와 학업성적, 비행경험, 약물사용 동료수, 지각된 약물의 입수용이도, 가족의 훈육도, 부모 외 일반적인 음주와 흡연에 대한 태도 및 자아개념 수준과 정신건강 수준을 조사하였다. 전체 표본을 사용하고 있는 약물의 수에 따라 남자 6집단, 여자 5집단으로 구분하여 위에 열거한 변인들이 집단에 따라 차이가 있는지를 검증하였다. 결과 우리나라 청소년들이 가장 많이 사용하는 약물은 담배와 술이었으며, 남자의 경우는 환각물질을, 여자의 경우는 진통진정제를 사용하는 이들이 상당수 있었다. 남자와 여자에게서 각 약물의 사용율을 전반적으로 차이가 있었으나, 그럼에도 불구하고 각 집단에 따른 변인들의 차이검증 결과는 크게 다르지 않았다. 일반적으로 여러종류의 약물을 사용하는 집단이 그렇지 않은 집단에 비해 학업성적이 낮고 비행경험 및 약물사용동료가 많았다. 또한 전자가 후자에 비해 비교적 낮은 정신건강수준과 자아개념수준을 나타냈다. 한편 차이를 나타냈던 여러변인들 중에서 무사용집단과 가장 많은 수의 약물을 사용하는 집단을 변별하는 두드러진 변인은 일반적인 적대감과 비행경험인 것으로 판별분석 결과 나타났다. 많은 종류의 약물을 사용하는 학생일수록 일상생활의 여러 측면에서 부적응적인 양상을 나타낸다는 본 연구의 결과는 약물의 사용은 공통적인 여러변인들과 관계가 있으며 많은 약물관련변인을 지닌 사람이 더 많은 약물을 사용하게 된다는 공통위험요인이론에 부합되는 것이라고 할 수 있다.
