This study examined emotion regulation, parental support, supervision, psychological control and marital conflict and victimization by peer harassment that affect children’s behavioral problems. The sample consisted of 412 fifth and sixth grade children. Statistics and methods used for the data analysis were percentage, frequency, Cronbach’s alpha, Factor analysis, t-test, Pearson’s correlation, and multiple Regression. Several major results were found from the analysis. First, girls had more internalized behavioral problems than boys. No sex difference was found in externalized behavioral problems. Second, boys’ and girls’ internalized and externalized behavioral problems showed positive correlations with maladaptive emotion regulation and parental psychological control. Boys’ and girls’ internalized behavioral problems and girls’ externalized behavioral problems showed negative correlations with parental support, but positive correlations with parentral marital conflict and victimization by peer harassment. Girls’ internalized and externalized behavioral problems showed negative correlations with parental supervision. Third, maladaptive emotion regulation was the most important variable predicting boys’ and girls’ externalized behavioral problems and girls’ internalized behavioral problems. Victimization by peer harassment was the most important variable predicting boys’ internalized behavioral problems.

The purpose of this study was to investigate adolescents' maladjustment in terms of type and source of social support. The main results of this study were as follows; 1. In social support source the mean score of peer support was higher than family support. In social support type the mean score of expressive support was higher than other support type. 2. Social support source was found significantly different according to sex of the children educational level of the father and mother and income. Social support type was found significantly different according to sex of the children educational level of the father and mother. Maladjustment were found significantly different according to sex of the children educational level of the father and mother Maladjustment were found significantly different according to sex of the children educational level of the father and mother income and marital satisfaction of the mother. 3. In social support source it was significantly it was signif cantly different according to all maladjustment subscale in family support and to over-anxiousness social withdrawal and hyperactivity in peer support. In social support type it was significantly different according to over-anxiousness hyperactivity and delinquency in esteem support and to over-anxiousness in informational support.

A peer-to-peer web caching has been studied recently as it can reduce the traffic converged on the server side and can support the traditional web caching model. Although the peer-to-peer web caching has the merit of having additional cache space from the local caches of peers without additional infrastructure, several constraints such as dynamic participation and local caching strategy caused by the autonomy of peers in peer-to-peer networks nay limit the performance of the peer-to-peer web caching. To overcome these limitations, we propose an efficient directory-based peer-to-peer web caching system under dynamic participation of peers. In the proposed caching system, we present new peer selection and replica management schemes by introducing the concept of the object lifetime in P2P networks. We evaluate the effectiveness of the proposed system through trace-driven simulations with a web log dataset. Simulation results show that the proposed system has higher accuracy and fewer redirection failures than the conventional directory-based P2P web caching system in feasible peer-to-peer networks.

This paper presents a P2P (Peer-to-Peer) overlay multicast tree construction algorithm to support stable multimedia service over the Internet. While constructing a multicast tree, it takes into account not only the link delay, but also peer stability. Since peers actually show dynamic and unstable behavior over P2P-based network, it is essential to consider peer stability. Furthermore, the weighting factor between link delay and peer stability is adaptively controlled according to the characteristics of the multicast tree. Basically, Genetic algorithm is employed to obtain a near optimal solution with low computational complexity. Finally, simulation results are provided to show the performance of the proposed algorithm.

Objective: This study examined the relationships between negative affect, social support, and career maturity among adolescents. Methods: The participants in this study comprised 260 $1^{th}$ junior high school students in a Seoul metropolitan area. They completed questionnaires on level of negative affect, social support, and career maturity. Data were analyzed by means of basic descriptive statistics, Pearson's correlations, and multiple and hierarchical regression analyses. Aiken and West's method was used to determine the interactive model's modality. Results: The major findings were as follows: First, negative affect was negatively correlated with social support and career maturity. Social support was positively correlated with career maturity. Second, significant interaction effects were found between negative affect and social support on career maturity; that is, for male students, significant interaction effects were found between negative affect and social support (parent support) on career maturity (career determinacy/career independence). For female students, significant interaction effects were found between negative affect and social support (peer support) on career maturity (career confidence/career readiness/career determinacy/career independence). Conclusion: These results suggest the need to intervene in relation to social support (parent support/peer support) and to improve career maturity among adolescents.

Purpose: The purpose of this study was to investigate the effects of peer mentoring program on physical activity, knee joint function, self-care agency and social support, which are health conservation elements in elderly women with osteoarthritis. Methods: This study used a quasi-experimental research design. It is a pretest-and-post 1, post 2 test design of a non-equivalent control group. The subjects were elderly women aged over 65 who were diagnosed with osteoarthritis. A total of 60 patients (experimental group 30, control group 30) who registered with the Senior Welfare Center in City G and in Region D participated in this study. The data were collected from June 29th to September 4th, 2015. The collected data were analyzed with $x^2$ test, Fisher's exact test, independent t-test and repeated measurement ANOVA. Results: The experimental group showed a greater increase in physical activity, knee joint function, self-care agency and social support than the control group. Conclusion: The results indicated that the peer mentoring program is effective in increasing physical activity, knee joint function, self-care agency and social support of elderly women with osteoarthritis.

The purpose of this study is to review the relationship between emotional labor and job burnout, and the moderating effects of peer and superior support in social welfare agency. In order to verify and achieve the purposes mentioned above, questionnaire data were gathered and analysed from 349 employees of social welfare agency in western Kangwon-do province. Empirical survey's findings are as follows; First, deep action(DA) appeared to be negatively related with depersonalization and reduced accomplishment. Second, surface action(SA) appeared to be positively related with all job burnout factors(emotional exhaustion, depersonalization and reduced accomplishment). Third, peer support moderated negatively the relationship between emotional labor(DA, SA) and emotional exhaustion. Fourth, superior support moderated negatively the relationship between deep action(DA) and emotional exhaustion.

This study examined relationships between peer variables and externalizing behavior problems of 290 4th and 5th grade children in elementary school. The children completed the Friendship Quality Scale and the peer nomination questionnaire. Parents and teachers rated behavior problems of children using the Connors' Rating Scale. Results indicated that rejected children had more behavior problems than popular, average, or neglected children. Socio-emotional supports from a close friend and satisfaction with the friend were negatively related to behavior problems. Behavior problems were mainly predicted by low peer acceptance, and behavior problems of rejected children were negatively and strongly related to socio-emotional supports of a close friend. In conclusion, peer rejection was a risk factor and a friend's support was a protective factor for externalizing behavior problems in 4th and 5th graders.

The growth of Internet technologies and the widespread use of mobile devices have been paving the way for the increasing use of conferencing services. Two types of systems have been designed to provide conferencing services: 1) a conferencing system using session control over a peer-to-peer (P2P) network and 2) an IP Multimedia Subsystem (IMS) conferencing system. The IMS conferencing system was developed to adapt to a server-based centralized system, whereas the benefits of the P2P operational model in providing such conference services are widely acknowledged. However, each system provides conferencing services only to its own users. Therefore, in this paper, we propose an interworking model to support multimedia conferencing service between the P2P environment and IMS networks. We also introduce protocol architecture and some service scenarios. To verify this system model and the design architecture, we perform an actual implementation and show experienced test results.

The purpose of this study was to investigate the moderating effect of negative emotionality on the association between mother-child intimacy and peer acceptance based on differential susceptibility model. According to differential susceptibility model, negative emotionality and difficult temperament is potential differential susceptibility factors. The participants were 3-year-old children recruited from preschools and daycare centers. Teachers completed measurement of negative emotionality. Peer acceptance was measured by peer nomination. Mother-child intimacy was reported by mothers. The results presented that negative emotionality significantly moderated the relation between mother-child intimacy and peer acceptance only for boys. For boys with high level of negative emotionality, mother-child intimacy significantly predicted peer acception. However, for boys with low level of negative emotionality, mother-child intimacy did not associate with peer acception. For girls, negative emotionality did not significantly influence the association between mother-child intimacy and peer acceptance. These findings support differential susceptibility hypothesis that vulnerable children are susceptible to positive parenting effects.
