Purpose： This study compared lifestyles of middle school students with and without atopic dermatitis in order to obtain the baseline information for health education. Methods： This study involved 256 students from 20 middle schools in Busan who suffered from atopic dermatitis and 231 students from 2 middle schools in Busan who did not have atopic dermatitis. Results： Students with atopic dermatitis had a lower family income (탑=16.99, p<.001) and were more likely to come from a nuclear family (탑=10.28, p<.001) than control students. 98% of the students with atopic dermatitis had several skin symptoms. 78.5% of students with atopic dermatitis reported experiencing difficulties in their daily because of their condition. Students with atopic dermatitis took shorter baths and used soap less frequently than the students in the control group. The students with atopic dermatitis cleaned their houses and bedclothes more often than normal students in an attempt to remove cockroaches and house-dust mites. Students with atopic dermatitis also ate fast and instant foods more often than normal students. Conclusions： Some lifestyle differences exist between students with and without atopic dermatitis.

Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

The purpose of this study is to analyze the mediating effects of anger level on the effects of middle school students' school adjustment on smartphone addiction. In order to accomplish the purpose of this study, the following research problems were set up. First, what is the relationship between Chinese smartphone addiction, anger level, and school adjustment of Chinese middle school students? Second, what is the effect of smartphone addiction on middle school students' anger level and school adjustment? Third, what is the mediating effect of the level of anger in the process of affecting the school adjustment to smartphone addiction by Chinese middle school students? The subjects of this study were five city schools and seven municipal schools in J-do, among which 450 students were enrolled from April 23 to May 18, 2018. A total of 439 copies were used for the analysis, except for 11 unexplained questionnaires or unfairly responded to the collected questionnaires. The conclusions based on the results of this study are as follows. First, there are negative correlations between the sub-factors of smartphone addiction and the sub-factors of school adjustment. Among them, tolerance is only positively correlated with the peer relationship. The sub-factors of smartphone addiction have negatively correlated with anger expression, anger control, and anger suppression. Second, the effect of sub-factors of smartphone addiction on the level of anger was 3.6%, and the effect on school adjustment was 4.2%. Third, The anger level of the middle school students affected the school adjustment by the smartphone addiction has a partial mediating effect of 0.8%.

This study examined the mediating effect of self-concept on the relationship of peer victimization and social anxiety in middle school students. Study participants consisted of 235 (122 boys and 113 girls) first to third graders from three middle schools located in Seoul and Gyung-gi province. The School Violence Experience Scale and the Self-Concept Scale were used to measure research variables in the Korean version of Social Anxiety Scale for adolescents. Descriptive statistics and Pearson's correlation coefficients were calculated to examine the general tendency of study variables. In addition, structural equation modeling(SEM) was used to examine the mediating model. The study results were as follows. First, the level of peer victimization of the middle school students decreased the self-concept level; in addition, the self-concept level had a significant negative effect on the social anxiety level. Second, the self-concept level fully mediated the peer victimization and social anxiety relationship. In conclusion, a higher peer victimization level resulted in a lower self-concept level, that produced a higher social anxiety level in middle school students. The results suggested that implementing effective interventions to prevent peer victimization and encouraging a positive self-concept in middle school students would make a significant contribution to reducing social anxiety.
