The purpose of this study was to examine the longitudinal relationships between Korean adolescents'mobile phone dependency, trajectories of depression, and self-regulated learning abilities. To achieve these goals, structural equation modeling analysis was conducted, using the 3rd, 5th and 7th wave of the data on 4th graders taken from the Korean Children and Youth Panel Survey. The results can be summarized as follows. First, growth-curve longitudinal analysis indicates that depression in 6th through 10th grade has increased. Second, mobile phone dependency among adolescents at 6th grade has a significant effect on both the initial value and the rate of change in depression. Also, the initial value and the rate of change in depression have significant relationships with mobile phone dependency at 10th grade. Moreover, both increased levels of mobile phone dependency and the rate of change in depression significantly influence adolescents'self-regulated learning abilities at 10th grade. Based on a longitudinal data set, these findings demonstrate the causal relationships between Korean adolescents'trajectories of depression and their mobile phone dependency. The findings also provide a comprehensive framework with implications for adolescents'development through an understanding of the relationships between adolescents'depression and mobile phone dependency, which impact their self-regulated learning abilities.

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.

본 연구는 다층 퍼셉트론 인공신경망을 이용하여 우리나라 중학생의 또래애착에 영향을 미치는 요인을 탐색하였다. 2016년 지역아동센터의 아동패널조사에 참여한 중학교 3학년 재학생 419명(남 210명, 여 209명)을 분석하였다. 종속변수는 또래애착 여부로 정의하였고, 설명변수는 성, 학업 성적 만족도, 주관적 가구경제수준, 학교생활에 대한 부모-자녀대화 빈도, 주관적 건강상태, 우울증상, 자아존중감, 주관적 생활 만족도, 휴대전화의존도를 포함하였다. 또래애착의 예측 요인은 다층 퍼셉트론 인공신경망 알고리즘을 이용하여 분석하였다. 분석 결과, 우울증상, 성, 학교생활에 대한 부모-자녀 대화 수준, 주관적 가구 경제수준, 주관적 건강상태는 청소년의 또래애착과 관련이 높은 요인이었다. 청소년기의 성공적인 사회관계 형성을 위해서 또래 애착에 주요한 영향을 미치는 요인들을 고려한 상담 및 교육 프로그램의 개발이 요구된다.
