It is difficult to provide a video on demand (VoD) service to a large number of users via the Internet. This is due to the characteristics of VoD, which require a large bandwidth for a long playing time. The Peer-to-Peer (P2P) concept is proposed to increase the scalability of the VoD service. Many studies have been undertaken to solve this problem. But its success is still quite limited technically, these research have been deployed in a rush, mostly based on practicality and instability. A system which uses a distributed VoD streaming scheme over P2P network is proposed to support media streaming.

This study examined four ecological systems, namely individual, family, school, and media environments. A series of moderator analyses were conducted to examine variations in effect size estimates across the study characteristics. The current study estimated that the effect size results were gleaned from 360 primary studies, including 90 journal articles and 270 thesis/dissertations, published between 2011 and 2022. The current meta-analysis results supported the ecological framework. That is, the impact of each ecological system on the development of positive and negative peer relationships varies depending on age groups and protective-risk factors. Specifically, for positive peer relationships, the largest effect size of the protective factor was found at the individual level for young and school- aged children, but at the school level for adolescents. Regarding the risk factors for positive peer relationships, the media was the ecological system with the strongest effect size for both young children and adolescents, while the individual-level demonstrating the strongest effect for school-aged children. Results from this meta-analysis allow us to identify some vital intervention areas in terms of healthy peer-relationship development, which should be of considerable interest to the educators and policymakers who are responsible for assessing and intervening with at-risk young children, school-aged children, and adolescents. From a practical standpoint, the current meta-analysis results are expected to contribute to developing effective prevention initiatives by targeting specific protective and risk factors for peer relationship development on the ecological system level.

This study investigated the relationships between socio-economic status of family, home environment stimulation, children's behavioral problems, and interactive peer play of preschool children. Surveys of 2,150 Korean mothers with their preschool children(Mean age= 51.9 months) from the Panel Study of Korean Children by Korea Institute of Child Care and Education were analyzed using structural equation modeling. Each variable's confirmatory factor analysis showed the correlation coefficient below .85, which made a satisfactory level of discriminant validity. The model fit to the data well, with an agreeable level of index. The major findings were as follows. First, SES did not significantly affected children's interactive peer play. Second, SES significantly affected home environment stimulation and children's behavioral problems. And the relationship between SES and children's behavioral problems are significantly mediated by home environment stimulation. Third, the relationship between SES and children's interactive peer play are significantly mediated by home environment stimulation and children's behavioral problems. These results help better understand the paths among the home characteristics and children's behavioral problems on children's social development. Interpretation and implication of the results have been discussed.

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.

Objective: The purpose of this study was to explore the pathway from mothers' overprotective parenting to their child's peer play interactions mediated by internalizing problems, that is, social immaturity and withdrawal. Methods: Surveys were conducted on mothers and teachers of 341 children aged three to five. SPSS 22.0 was used to analyze the data using descriptive statistics. Structural modeling analysis was also implemented to test theoretical model using AMOS 21.0. Results: Maternal overprotective parenting, which increased social immaturity of their child, indirectly reduced the child's positive interactions with peers during play. Mothers' overprotection led to a higher level of withdrawal of their child while the effect of children's withdrawal on their peer play interaction was not significant. Because overactive parenting of mothers had no direct effect on peer play interaction, the complete mediation model representing a path from maternal overprotection to children's peer play interaction via their internalizing problems was partially supported. Conclusion/Implications: This study shows that overprotective mothers hinder their child to experience confident and mature manners, and eventually lead their child to be socially unskillful and incompetent. It was suggested to explore more individual characteristics of mothers and children to help overprotective mothers to take a step back.
