In simple topology in network system, query should be delivered to all linked peers for query processing. This causes waste of transmission band width and throughput of each peer. To overcome this, as well as query processing strategy, efficient routing technique to deliver query to proper peer is needed. For efficient routing, clustering of peers in P2P networks is important. Clustering of P2P network bases on that combines peers that have similar characteristics in same cluster reduces quantity of message in network than assign peer for cluster randomly. In this paper, we propose clustering techniques for ontology based P2P query processing. Similarity measure point, cluster index structure, and query processing steps in ontology based P2P cluster environment are proposed.

This study aimed to examine the direct effects of relationships with parents, peers, and community child center teachers on the school adjustment of low-income adolescents attending community child centers and the indirect effects mediated through adolescents' resilience. The second-term panel data from the fourth-year Community Child Center Survey was used to analyze 198 adolescents (103 boys, 95 girls) who were first graders at middle schools. SPSS 20.0 and AMOS 20.0 were used to analyze the data through structural equation modeling. The results of the study were as follows: Parental monitoring and peer trust had direct effects on the adolescents' school adjustment, while satisfaction with community child center teachers did not. Parental monitoring, peer trust, and satisfaction with community child center teachers had indirect effects on adolescents' school adjustment mediated through resilience. The school adjustment of low-income adolescents has received attention from both researchers and politicians. The results of this study are notable in that both the important relationships and resilience of low-income adolescents can significantly contribute to their school adjustment in their first year at middle school. Given the developmental needs of low-income adolescents, interventions for school adjustment that consider adolescents' important social contexts and psychological characteristics should be developed.

Recently, purchasing expensive branded apparel became prevalent among adolescents as they consume conspicuously. People in their adolescence strongly tend to follow peers and are very likely to pay attention to how they wear look to others. Already a good deal of prior research about young people's conspicuous consumption have focused on variables related to these behaviors. The purpose of this study is to examine demographic characteristics of adolescents who show a conspicuous consumption and factors affecting this consumption which is related to peer relations. And we will examine how negative emotions arisen out of relations influence teenagers' conspicuous consumption of branded apparels ultimately. Being out of favor from peers has an effect on anxiety which is negative emotion in association with peer relations. According to the survey, adolescents did conspicuous consumption following others or following trends to get rid of anxiety. Also, if appears to be acting on clothing consumption as a means not to be marginalized. All these findings are expected to be useful information to adolescents to have a better habit of consumption life, and also anticipated to be valuable information for consumer behavior education. The cause of youth's show-off behavior, which is still incomplete in identity formation and immature in choice and judgement, will have to be analyzed and countermeasures taken against it.

In a group of 353 elementary students, the present study examined the moderation effects of prosocial behaviors and social competence in the relations between overt/relational aggression and peer status (social preference and perceived popularity). The results indicate that both overt aggression and relational aggression lowered social preference regardless of gender. Prosocial behaviors and social competence did not buffer the negative influence of aggression on social preference. Among boys, overt aggression was a significant predictor of increased perceived popularity. Although inconsistent, relational aggression also predicted boys' perceived popularity. However, among girls, relational aggression, not overt aggression, was associated with perceived popularity. The moderation effects of prosocial behaviors and social competence were significant only among boys. In other words, boys' aggression, although it lowers social preference, contributes to their social influence and dominance when it is effectively combined with positive characteristics. It is necessary to develop new intervention strategies which reflect the adaptive function of aggression within peer groups.

Objectives : The degree of depression in dental hygienist was analyzed to reveal the various factors related to them. Methods : The self-administered questionnaires were filled out from 202 dental hygienist in Daejeon City. The survey items included subjects' socio-demographic and job-related characteristics, health-related behaviors, depression. Chi-Square analysis and Pearson's correlation coefficient was put into survey results, in which a degree of depression was dependent variable and others were independent variable. Results : 1. The distribution for depression degree has shown the rate as 80.2% in normal range group and 19.8% in depression group. 2. As for depression, long working hours(p=0.042), poor sense satisfaction in work(p=0.000), not fit to the job(p=0.003), low personal relation with peer works or supervisors(p=0.039), without alcohol drinking(p=0.048), poor subjective condition of health(p=0.000) than their respective counterparts. 3. Concerning correlation between depression and various factors, poor sense satisfaction in work(r=-0.332, p=0.000), not fit to the job(r=-0.353, p=0.000), low personal relation with peer works or supervisors(r=-0.215, p=0.002), without alcohol drinking(r=-0183, p=0.009), poor subjective condition of health(r=-0.333, p=0.000). Conclusions : These results showed that depression state could be influenced by various factors, which include socio-demographic, job-related characteristics and health-related behaviors. Therefore, in order to reduce depression state of dental hygienists, development and application of programs to manage and research for them are required to be revitalized as well as socio-demographic and job-related characteristics and health-related behaviors.

The purpose of this study was to examine the social resilience group of adolescents exposed to family violence, the influences of environmental protective factors on their social resilience, and buffering effects of environmental protective factors. The sample consisted 795 high-risk group exposed to family violence. The findings are as following. First, 43.3% of adolescents witnessed father-mother violence and 43.1% of adolescents experienced violence by parents had social resilience. Second, the higher level of family support, prosocial characteristics of peer group and other adult's support were more likely to be increased social resilience. Third, prosocial characteristics of family support, prosocial characteristics of peer group and other adult's support had a significant buffering effect moderating negative influence of family violence to their social resilience.

The purpose of this study is to verify antecedent variables that positively influence behavioural engagement during school engagement, which is critical to adolescent socialization. The antecedent variable was categorized into the personal characteristics of adolescents who are the main agents of socialization and peer support and teacher support, which can be called social support at school sites. Individual characteristics include strength recognition, strength utilization, and learning goal orientation, and, peer supports include the supports for personality strength and academy, and, teacher supports include the supports for personality strength and perspective change. For this study, a survey was conducted on 539 high school students nationwide, collected data, 33 of them were removed, and 506 data were analyzed. Analysis shows that only learning goal orientation set as a sub-factor of individual characteristics has a static significant effect on behavioral engagement. Finally, based on the findings, we discuss the implications, limitations, and future research tasks of the study.

Using the second year data of the Korean Child and Youth Panel Survey (KCYPS) elementary 4 panel, this study attempted to elucidate variables related to elementary school 5th graders' life satisfaction and how the variables are clustered in each gender. Analyzing the data of 2378 5th graders (boys 1180, girls 1084) indicated that variables related to their life satisfaction were self-esteem, parenting style, peer attachment, grade satisfaction, and school adjustment. Both boys and girls were clustered into three clusters. The cluster 1 children indicated the highest degrees of self-esteem, peer attachment, grade satisfaction and school adjustment levels, and they perceived parenting style more positively than the children from the other clusters. The cluster 3 children showed the opposite trends to the cluster 1 children in each of the five variables and the cluster 2 showed middle levels in all of the variables. The characteristics of the three clusters were analyzed in terms of the differences of children's life satisfaction and explanatory variables of life satisfaction.

The first wave of e-government projects dating from the early 1990s primarily focused on setting up national and global information infrastructure, internal organizational reform, digital procurement, and the digital delivery of government services to citizens. Most of these e-Government projects have concentrated on the development of systems focusing on strengthening the formal agencies and institutions of government. To date, despite many theoretical and empirical studies on citizen involvement in terms of governance, relatively little attention has been paid to developing e-government systems with a focus on improving citizen involvement, which we call e-governance systems. This paper discusses the characteristics of the e-governance systems, identifies core requirements for its development, and suggests an e-governance system architecture that can satisfy the core requirements.

The importance of algorithm education has been emphasized for creative problem-solving capability. Especially, algorithm teaching materials related with mathematics and science are under development to enhance logical thinking. However, there are not enough teaching-learning models applicable in the field of education. Therefore, this paper proposed a teaching-learning model for effective algorithm education. The teaching-learning model reflects two characteristics : an algorithm learning process is spiral, and algorithm education is based on logical thinking. Furthermore, a survey was conducted for students' satisfaction, and the result was a mixed teaching-learning model with PBL, SDL, and peer tutoring. Based on the proposed model, examples of classes for mathematics and science are suggested to show the feasibility of effective algorithm education.
