The purpose of this study was to examine the effects of adolescents' mobile phone dependency on depression and aggression and to identify mediating effects of parenting attitudes and peer relationships. This study used data from the 4th and 5th waves of 2010 KCYPS (Korean Children and Youth Panel Survey). Structural Equation Model(SEM) was conducted to examine the mediating effects of parenting attitudes and peer relationships. The results showed that adolescents' mobile phone dependency had positive effects on depression and aggression. In addition, the relationship between adolescents' mobile phone dependency and depression was partially mediated by parenting attitudes and peer relationships. The relationship between adolescents' mobile phone dependency and aggression was also partially mediated by parenting attitudes and peer relationships. Based on these findings, further suggestions are provided to reduce adolescents' depression and aggression by decreasing mobile phone dependency and improving parenting attitudes and peer relationships.

The purpose of this study was to verify the impact of maltreatment by parents on adolescents' depression, furthermore, confirm the mediating effects of social withdrawal and cell phone dependency in South Korea. The data were analyzed with frequency, correlation and structural equation modeling(SEM) by SPSS 18.0 and AMOS 20.0. Data was employed from the wave 5 in 2014 of Korean Children and Youth Panel Study (KCYPS), and analyzed data of 1,969 fourth grade elementary school students. The result showed: First, maltreatment experience from parents has a statistically significant positive effect on adolescent's depression. Second, maltreatment experience from parents has positive effects on both social withdrawal and mobile phone dependency. Third, both social withdrawal and mobile phone dependency have positive effects on adolescent's depression. Fourth, both social withdrawal and mobile phone dependency have significant mediating roles in the relationship between maltreatment experience from parents and adolescent's depression.

This study aimed to examine the mediating effects of social withdrawal between adolescents' mobile phone dependence and the sense of community, and to secure the evidence data for adolescents' mobile phone dependence intervention. Among the 7th year data for the 4th grade students in the Korean Children & Youth Panel Survey(KCYPS), 1,979 students were included. The results showed that mobile phone dependence had a significant effect on the decrease in the sense of community and influenced the sense of community through social withdrawal. These results imply that positive intervention to reduce social withdrawal is needed and it can improve the sense of community in youth. Also, when we deal with weakening in the sense of community, we should consider convergent intervention in psychological and social aspects which deal with dependency, social withdrawal, and the sense of community.

This study aims to examine whether a Parent's Neglecting Attitude affects an Adult Media Immersion and Adolescent' Dependence on mobile phonehas a mediating effect. To achieve this goal, the first year of middle school panel of 'the 6th Korean Children and Youth Panel Survey(KCYPS)' was utilized. To verify the mediating effect of Adolescent' Dependence on mobile phone in the relationship between Parent's Neglecting Attitude by Adolescents and the Adult Media Immersion, Baron & Kenny's mediating effect analysis method was conducted and the analytical findings are shown below. According to this study, first of all, more the Parent's Neglecting Attitude rise to rise the Adult Media Immersion. Second, the Adolescent's Dependence on mobile phone partly mediates the Adult Media Immersion. The practical implications of this results are below : First, we need to make a policy and legal effort to improve the relationship between parents and children. Second, there is a need to practice professional programs in schools, focusing on school social worker. Third, Revision of relevant laws limiting access to adult media is necessary.

Objective: The purpose of this study was to examine the bidirectional relation between mobile phone dependency (MPD) and self-regulated learning (SRL) of early Korean adolescents in $4^{th}$, $6^{th}$ and $8^{th}$ grade, while taking into account gender differences. Methods: The study made use of panel data from the Korean Children and Youth Panel Study (KCYPS), and three waves of data collected from 2,264 adolescents were analyzed by means of autoregressive cross-lagged modeling. Results: The results can be summarized as follows. Firstly, MPD and SRL were consistently stable for adolescents in $4^{th}$, $6^{th}$ to $8^{th}$ grades. Secondly, a bidirectional relations between MPD and SRL were confirmed. In other words, there was a significant influence of a high level of MPD on a subsequent low level of SRL, and the high level of SRL also had a significant effect on the lower level of MPD across time. According to multi-group analysis, no gender differences were found in the relations between two constructs during the studied period. Conclusion: Findings highlighted not only the necessary media usage education but also parenting intervention strategies may help early adolescents to be prevented from negative effects of media usage and to enhance self-regulated learning ability. Based on the results, more implications were also discussed.

The purpose of this study was to examine the relationships among Korean early adolescents' perceived negative parenting practices, trajectories of mobile phone dependency(MPD), and self-regulated learning(SRL), while taking into account gender differences. Early adolescents are required to acquire self-regulation in Korean cultural contexts of a strong emphasis on academic achievement and recent technological advancements. The study made use of data from the Korean Children and Youth Panel Study(KCYPS), and three waves of data collected from 1,953 adolescents in $7^{th}$, $8^{th}$ and $9^{th}$ grade were analyzed. The results can be summarized as follows. Growth-curve longitudinal analysis indicates that their initial value of MPD through $7^{th}$ to $9^{th}$ grade had increased, but the initial value and rate of change were significantly different according to gender. Furthermore, the results of multiple group analysis revealed that some path weights appeared different according to gender. For male students, the rate of change in MPD did not have a significant effect on either SRL in $7^{th}$ or $9^{th}$ grade, whereas for female students, it predicted the existence of significant relationships with them. The implications of these findings were also discussed.

The purpose of this study was to examine the effects of peer attachment and parental abuse on adolescents' dependence on mobile phones and the mediating effect of self-esteem. For this study, I used the panel data of the 7th year of the 1st grade of the elementary school for the Korean Children and Youth Panel Survey provided by the Korea Youth Policy Institute. A total of 1,937 adolescents were selected to analyze causal relationship among variables, and SPSS 26.0 and AMOS 26.0 were used to verify research problem. As a result of the study, First, the better the relationship with peers, the higher the self-esteem and the less the dependence on their mobile phone. On the other hand, the more severe the abuse, the lower the self-esteem and the higher the dependence on mobile phones. Second, Self-esteem was found to have a significant effect on peer attachment and abuse on mobile phone dependence. Based on these results, I would like to provide them as basic data for helping positive development of adolescents.

본 연구에서는 급증하는 청소년기 휴대폰 의존 문제의 심각성에 주목하여 우리나라 청소년들의 휴대폰 의존이 시간의 흐름에 따라 어떠한 변화 양상을 보이는지 실증적인 검증을 실시하고자 하였다. 이를 위하여 한국아동 청소년패널조사(KCYPS) 중학교 1학년 1~4차년도 자료에 대하여 이차잠재성장모형(second-order latent growth modeling)을 이용하여 휴대폰 의존의 발달궤적을 확인하였다. 휴대폰 의존의 발달궤적에 대한 최적의 모형을 찾기 위해 다수의 모형을 구성하여 비교 검증하였으며, 그 결과, 이차함수모형에 대하여 오차 간 공분산을 설정하고, 시간의 흐름에 따른 측정동일성 제약을 가한 후, 오차 간 공분산에 대한 동일화 제약을 가한 모형이 가장 좋은 적합도를 보이는 것으로 확인되었다. 이렇게 도출된 모형에 의하면, 중학교 1학년부터 고등학교 1학년까지 휴대폰 의존 정도는 증가하다가 그 증가율이 둔화되는 이차함수모형의 변화를 보이는 것으로 나타났다. 이러한 결과에 근거하여 청소년기 휴대폰 의존에 대한 예방 및 개입과 관련된 함의를 제시하였다.
