The purpose of this study was to analyze the effects of adolescents' Internet Usage Levels on their oral symptoms using the data from 60,040 students in the 14th Korea Youth Risk Behavior Web-Based Survey in 2018. The logistic regression for the effects of Internet Usage Level on the oral symptoms were analyzed using a logistic regression method. Symptoms of toothache when eating and throbbing symptoms, and gum pain symptoms showed high levels of stress, and high awareness of pain when lower daily frequency of tooth-brushing. In addition, the less time spent on the Internet, the more subjective health awareness, the higher sleep satisfaction, the less smoking and drinking experience, Results were significantly lower. In conclusion, health education that mitigates adolescents' excessive use of the Internet is believed to enable proper health practices and is intended to help develop health education programs that can prevent such oral symptoms.

This study examined the relationships among smartphone addiction, parenting attitudes and resilience to identify the relevant factors affecting smartphone addiction. Data were collected from a total of 220 middle school students responding to questionnaires in G city and analyzed using descriptive statistics, independent t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson coefficient correlation, and multiple regression. The results showed that the parenting attitude and resilience were negatively correlated with smartphone addiction. The significant factors affecting smartphone addiction were gender, the time of smartphone usage, parenting attitudes, and resilience. These variables explained 21.9% of smartphone addiction and the highest factor was the parenting attitudes, followed by gender, time of smartphone usage, and resilience.

This study explores the influence of parents socio-economic status on their adolescent children s internet use and learning conduct based on Korean Time Use Survey of 2014, under the assumption that parents socio-economic status can function as a mechanism for reproducing inter-generational inequality due to the difference of their children s internet use and learning conduct. Upon reviewing the weekdays average hours of using internet per day for the students from the age 13, the first year of a middle school to the age 18, the third year of a high school, they spend 15 minutes for information search, and 54 minutes for computer or mobile games. They tend to spend 211 minutes for study in the school, 56 minutes for after school study, and 88 minutes for self-study. According to Tobit regression analysis, the higher the students parents socio-economic status, the bigger the total hour for self-study and after school study. On the other hand, the lower the parents socio-economic status, the bigger the total hour for their adolescents internet or mobile game. The research shows that the lower the parents socio-economic status, the bigger the risk of their adolescent children s exposure to the addiction of the internet and mobile game. This implies that the parents socio-economic status can function to reproduce the inter-generational inequality. Based on the analysis result, this study discusses the practical and policy level implications in social welfare for improving the inequality reproducing mechanism.

This study was a secondary data analysis using statistics from the 13th (2017) Korea Youth Risk Behavior Web-based Survey (KYRBS) to investigate the relationship between health behaviors and physical activity among Korean adolescents. A total of 62,276 adolescents in middle and high schools enrolled in this study. Physical activity utilized moderate and vigorous physical activity variables. Health behaviors used smoking, drinking, eating, sedentary behavior, and sleep duration variables. Statistical analyses were performed applying complex sample analysis method. Chi-square tests were used to compare physical activity according to health behaviors. Multivariate multinomial logistic regression analyses were conducted to examine the relationship between health behaviors and physical activity, adjusted for general characteristics. Current smoking and current drinking were associated with high levels of moderate and vigorous physical activity. Consuming fruits≥1 times/day, vegetables≥3 times/day, and sweet drinks≥3 times/week were associated with high levels of moderate and vigorous physical activity. Eating breakfast≥5 times/week was associated with high levels of moderate physical activity, but not with vigorous physical activity. Sedentary behavior≥2 hour/day was associated with low levels of moderate and vigorous physical activity. Sleep duration<7 hour/day was associated with high levels of moderate physical activity and low levels of vigorous physical activity. These findings suggest that since there is an interrelationship between health behaviors and physical activity among adolescents, intervention programs aiming at promoting physical activity and healthy lifestyles should consider a multiple behavior approach rather than an individual behavior approach.

This study examined the effects of smartphone usage types and excessive expectation for smartphone on adolescents' smartphone overdependence. It utilized the data of 3,454 adolescents (1,758 males and 1,696 females), aged between 13 and 19 from a smartphone overdependence survey of the National Information Society Agency. As a result of the hierarchical multiple regression analysis, age and household income had a negative effect on smartphone overdependence. Weekly smartphone usage time positively affected the serious consequences (sub-factor of smartphone overdependence). Among the different types of smartphone usage, information seeking, SNS, gaming, and the excessive expectation for smartphones had positive impact on smartphone overdependence. Smartphone usage for leisure seeking did not affect smartphone overdependence, but it negatively influenced serious consequences. Messenger use did not affect smartphone overdependence, but the use had a positive effect on salience, and a negative effect on serious consequences. The results of this study suggest that it is necessary to identify the types of smartphone use as well as the usage time to understand the smartphone dependence of adolescents. In addition, it seems necessary to recognize and correct the irrational excessive expectation for smartphone in order to prevent dependence and implement effective interventions.

정보통신기술과 컴퓨터의 보급은 다양한 정보통신 서비스 이용의 보편화와 청소년 들의 미디어 이용 형태에 큰 변화를 가져왔지만, 지적 재산권의 침해, 사생활 침해, 불건전 정보 유통, 컴퓨터시스템 파괴 등 정보통신윤리측면에서 문제를 야기 시키고 있다. 위와 같 은 문제점을 해결해 나가기 위하여 대구·경북지역의 청소년들을 대상으로 정보통신윤리의식 에 관한 실증조사를 실시한 결과, 정보통신윤리의식은 여성이 남성보다 높고, 학력별로는 고등학생이 대학생보다 높고, 거주지역 벼로는 중소도시의 청소년들이 대도시보다 상대적으 로 높은 윤리의식을 가지고 있는 것으로 나타났다. 또한 컴퓨터 이용시간이 많을수록, 그리 고 컴퓨터 사용경력이 많을수록 불건전 정보유통에 대한 윤리의식은 낮은 결과를 보이고 있 다. 컴퓨터범죄와 일반범죄와의 인식차이는 여성이 남성보다 인식정도가 높게 나타났으며, 불건전정보 유통 경험에 대한 윤리의식은 고등학생이 대학생보다 높은 것을 알 수 있다.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.
