The present study investigated maternal parenting stress trajectories, using data gathered from the Korean Children Panel Survey. Four factors-monthly income, maternal depression levels, infants' negative emotionality, marital conflict-which were taken from reports made by the mothers' used in this study, were examined as predictors of maternal parenting stress trajectories. The effects of maternal parenting stress trajectories, parenting styles and toddlers' peer interruptive behaviors were also examined. The findings were as follows: First, maternal parenting stress trajectories somewhat increased from the 1st year period to the 4th year period. Second, infants' negative emotionality and marital conflict within the first year were observed to have a connection to the initial level and slope of maternal parenting stress trajectories. Third, maternal parenting stress trajectories predicted positive parenting styles, and parenting styles had a longitudinal impact on toddlers' peer interruptive behaviors at the 5th year period.

In order to achieve faster content distribution speed and stronger fault tolerance, a P2P peer can connect to multiple peers in parallel and receive chunks of the data simultaneously. A critical issue in this environment is selecting a set of nodes participating in swarming sessions. Previous related researches only focus on performance metrics, such as downloading time or the round-trip time, but in this paper, we consider a new performance metric which is closely related to the network and propose a peer selection algorithm that produces the set of peers generating optimal worst link stress. We prove that the optimal algorithm is practicable and has the advantages with the experiments on PlanetLab. The algorithm optimizes the congestion level of the bottleneck link. It means the algorithm can maximize the affordable throughput. Second, the network load is well balanced. A balanced network improves the utilization of resources and leads to the fast content distribution. We also notice that if every client follows our algorithm in selecting peers, the probability is high that all sessions could benefit. We expect that the algorithm in this paper can be used complementary to existing methods to derive new and valuable insights in peer-to-peer networking.

The present study examined differences in children's behavior problems and peer interaction, and parental factors including self-esteem, depression and childrearing stress between atopic dermatitis(AD) and normal(non-AD) children in each gender, and analyzed the effects of the parental factors on the two variables of AD children. 165 AD and 1176 non-AD children of age 5 were selected from the 6th year data of the Panel Study on Korean Children. The results from t-test and multiple regression are as follows. First, only AD boys showed a higher level of behavior problems than non-AD boys, but peer interaction showed no difference between AD and non-AD groups. Compared with non-AD children's parents, mothers of AD children showed a higher stress level and mothers of AD boys had a higher depression level. But there were no differences in maternal self-esteem and paternal factors between the groups. Second, AD boys' behavior problems were related to maternal factors and paternal stress, and some characteristics of AD girls' behavior problems were related with some parental variables. But peer interaction of AD children had no relation with parental factors. Third, behavior problems were influenced by maternal stress in AD boys and influenced by maternal depression and parental self-esteem in AD girls.

The purpose of this study is to analyze the structural relationship, direct and indirect effects between adolescents' peer attachment, self-resilience, academic stress, and smartphone addiction. The subject of this study used panel data of a total of 1280 middle school students who participated in the 14th study of the Children's Panel of the Korea Child Care Policy Institute. For data analysis, SPSS 24.0 and AMOS 24.0 programs were used. As a result of the study, children's peer attachment was positively correlated with ego resiliency, academic stress and negatively correlated with smartphone addiction. All pathways except peer attachment and smartphone addiction were found to have a direct influence, and adolescents' peer attachment had an indirect effect on smartphone addiction through ego resiliency and parental achievement pressure. In conclusion, in order to lower adolescents' smartphone addiction, practical interventions to improve ego resiliency and reduce academic stress through peer attachment are considered necessary.

The purpose of this study was to explore the general tendencies of major variables and sex differences and to analyze the variables that affect delinquency and aggression. The protective factors considered in this study included parental education participation, parental supervision, and peer attachment, and the risk factors were academic stress and delinquency experiences of peers. The main results of this study are as follows: firstly, academic stress and parental education participation was slightly low, but parental supervision was high. Further, peer attachment showed a very high score. Delinquency experiences of peers, delinquency, and aggression of adolescents were extremely low. Secondly, the correlation of parental education participation, parental supervision, and peer attachment was negatively related to adolescent delinquency, but the delinquency experiences of peers were positively related to adolescent delinquency. The same results were obtained in the case of adolescent aggression. Further, academic stress was negatively related to adolescent aggression. Finally, hierarchical regression revealed that the variables explaining the juvenile delinquency were parental education participation, peer attachment, and delinquency experiences of peers. Adolescent aggression was explained by sex, academic stress, parental education participation, and the delinquency experiences of peers. In particular, more attention is needed for girls. Various interventions should be provided to prevent problem behaviors.

The purpose of this study is to explore the potential of peer coaching for EFL teachers' professional development. For this study, 12 college teachers in Korea participated in a 10-week program. They were 7 males and 5 females, ranging in age from 24 to 37 years. Data were collected through semi-structured interviews. Reflective analysis was used to analyze individual interview data. From the findings, two significant categories of peer coaching were identified: positive and negative responses to peer coaching experience. However, the overriding themes that emerged from the data were the benefits of peer coaching. The participants were almost unanimous in their acknowledgement of the advantages of peer coaching, such as reflective support through other's eyes, improved working environments, greater teaching strategies, higher professional self-esteem, and awareness of self-directed learning. Negative responses also appeared, mostly in regard to the working principles of implementation; the major issues of difficulties were time management, complexities of implementation procedure, stress and personal vulnerability, and relative lack of reflection and feedback skills. Demonstrating the participants' experiences towards the peer coaching program, this study provides EFL teachers with useful insights into peer coaching as an effective tool of their professional development.

This study aims to present basic data for preventing drop-out intention by identifying the mechanisms in which academic stress affects drop-out intention through self-esteem, peer relationships, and grit in high school students. The subjects of the study were 283 high school students purposively selected from three cities and counties in Chungcheongnam-do. The data were analysed using SPSS PC+ Win. ver. 25.0 and SPSS PROCESS macro ver. 4.2. The applied statistical techniques were descriptive statistics, reliability analysis, correlation analysis, and moderated mediation effect analysis. As a result of the study, first, academic stress showed a positive correlation with the drop-out intention, but a negative correlation with self-esteem, grit, and peer relationship. Second, grit not only played a moderating role in enhancing the relationship between self-esteem and peer relationship, but also played a moderated mediating role in the path of academic stress → self-esteem → peer relationship → drop-out intention. It was confirmed that the academic stress of high school students has a direct effect on the drop-out intention, and that self-esteem, peer relationships, and grit can be used as important factors to prevent the school drop-out.

The effects of environmental factors on adolescent’s socialization were examined according to the gender. Data were drawn from 1,412 adolescents. A hypothesized model was tested for male and female students separately by the links among housing, family conflicts, parent-adolescent relationship, family stress, peer relations, mass media, school atmosphere, consumption, consumer socialization, and adolescent’s socialization. There was no difference between male and female students in the predictability of the effects of environmental factors on internal and external socialization. For male students, the internal socialization was directly related to mass media, consumer socialization, peer relations, family stress, mother-adolescent relations, and school atmosphere. The external socialization was directly related to mass media, school atmosphere, consumer socialization, father-adolescent relations, housing, and mother-adolescent relations. For female students, the internal socialization was directly related to mass media, peer relations, father-adolescent relations, and consumer socialization. The external socialization was directly related to mass media, followed by consumer socialization, mother-adolescent relations, school atmosphere, housing, and peer relations. The findings are consistent with a growing body of literature showing that the environmental factors are related to male & female adolescent’s socialization.

This study explored how peers influence on adolescents' game over-indulgence. More specifically, it was examined the effects of emotional support, subjective norm of game use, peer stress, and friends' attitude toward gaming on game over-indulgence. Results showed that the higher level of subjective norm of game use and peer stress one received the higher level of game over-indulgence one reported. However, lower emotional support caused higher game over-indulgence. Meanwhile, friends' attitude toward gaming was not significantly related to game over-indulgence. The meaning and the importance of peer in terms of game over-indulgence and limitations of the study were discussed.
