The purpose of this study is to investigate children's emotional regulation and social competence in relation with peer friendliness. Specifically, it examined the hypotheses that children's emotion regulation strategies would be different depending on age, gender, and peer friendliness, and that children's emotion regulation strategies would affect their social competences. The subjects were 197 of the second, fourth, and sixth graders in an elementary school located in Gangdong-gu, Seoul. The findings are as follows: first, children's emotion regulation strategies are different according to gender and age. Girls use more 'external response strategy' than boys do. Elder children use more 'internal response strategy' than younger children, and younger children use more 'problem solving strategy' than elder children. Second, children's emotion regulation strategies are different depending on the degree of peer friendliness. Children employ more 'problem solving' and 'internal response' strategies to close friends rather than to just friends. Children used more the strategies as 'request for social support', 'evasion', and 'external response' to just friends rather than to close friends. Finally, children's social competencies are influenced by the strategies of 'problem solving' and 'evasion'.

The purpose of this study was to analyze the teacher-child relationship as it is self-conceived by teachers in regards to children's peer-competence and self-regulation and to also examine how the teacher-child relationship affects peer-competence and self-regulation. 17 teachers were surveyed using the Student-Teacher Relationship Scale, Peer-Competence Scale and Self-Regulation Scale in regard to approximately 270 children (aged 4-5 years old). Our results indicated that the pro-sociality, sociality, and leadership qualities of child peer-competence correlated positively with the friendliness of teacher-child relationships but correlated negatively in cases of conflicts within the teacher-child relationship. The factors of self-appraisal, self-determination and behavior inhibition of child self-regulation were found to be positively related with the friendliness of teacher-child relation but related negatively with presence of the conflict within the teacher-child relationship. It was also found that sociable and self-determinative children tended to be on more friendly terms with teachers.

This study investigated the influence of peer friendliness, conflict, and collaboration on children's problem solving performance. Eighty-two preschool children (41 pairs) filled out the Friendship Assessment Inventory and participated in 3 problem-solving sessions using the Tower of Hanoi. Results showed that just working together does not improve children's problem solving performance. The degree of friendliness children have for each other has a significant effect on their problem solving performance. The children who worked with more friendly peers were more collaborative and were better problem solvers than those who worked with less friendly peers. This study suggests the importance of the relationship between interacting peers on problem solving performance.

Subjects in this study on causal relationships among playfulness, interactive peer play, teacher-child relationships, and creative characteristics were 286 3- to 5-year-old children. Instruments were the Rating Scale for Creative Characteristic of Preschoolers (Lee et al., 2002), Children's Playfulness Scale (Bemett, 1990), Penn Interactive Peer Play Scale (Fantuzzo et al., 1995), and Student Teacher Relationship Scale (Pianta, 1991). Results showed : (1) significant relationships among social spontaneous, cognitive spontaneous and children's humor in sub-areas of children's playfulness, friendliness in sub-areas of teacher-child relationships, play interaction in sub-areas of interactive peer play and creative characteristics. (2) Children's creative characteristics directly influenced social spontaneous, cognitive spontaneous and children's humor in sub-areas of children's playfulness and of play interaction in sub-areas of interactive peer play.

Peer-to-peer systems (P2P) are rapidly growing in importance on the Internet environment, quickly extending the range of their usage. However, peer-to-peer systems have not been widely applied in electronic commerce because they have not been established as an appropriate business model. Therefore, we firstly review the previous research relevant to peer-to-peer systems, and then analyze the business models for P2P systems presented by previous researchers. Furthermore, this study categorizes major issues in terms of the technical and business model aspects. On the basis of these reviews, we develop P2P electronic commerce systems based on the file sharing method between users, focusing on user interface friendliness. A developed P2P electronic commerce systems are programmed by using the C# based on the Microsoft.net solution. A database is implemented using the MSSQL2000. A main application technology is designed that P2P electronic commerce systems make it possible. for user to extend into BtoB Solution by using WSDL (Web Services Description Language), UDDI (Universal Description, Discovery, and Integration) and the XML that is a document for users. User interface is made as form of Internet messenger for a user's convenience and is possible to develop into a commodity transaction system based on XML. In this study, it is possible for the P2P electronic commerce system to have extended application to fields such as Internet shopping mall and property transaction in a nonprofit organization, a public institution and a large scale nonprofit institution that have a similar structure as compared with a structure of a nonprofit educational institution.

본 논문은 CORBA, Ice 등의 다른 미들웨어들과 비교하여 성능, 품질, 사용자 편의성 등에서 높은 평가를 받고 있는 공개 메시지 지향 미들웨어인 ZeroMQ 기반의 다중 에이전트 메시지 전송 구조를 제안한다. 제안 구조는 FIPA 에이전트 표준 규격들로부터 MTS(Message Transfer System) 등의 개념들을 빌려와 사용하고 있으며, 다중 에이전트 플랫폼 SMAF(Smart Multi-Agent Framework)의 구조적 장점을 계승한다. 제안 구조는 ZeroMQ 커뮤니티에 알려져 있지 않은 새로운 방식의 피어 대 피어 구조를 사용한다. 제안 구조는 MTS 마다 단 하나의 라우터 소켓만을 사용하여 MTS들 간의 피어 대 피어 통신을 지원한다. 제안 구조는 ZeroMQ가 지원하는 다양한 장치들과 패턴들에 대한 호환성과 확장성을 가지며, 전통적인 분산 에이전트 응용 분야들 뿐 아니라 에이전트들 간의 밀접한 협력을 필요로 하는 지능형 로봇과 같은 분야도 지원할 수 있다.
