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.

This paper suggests a multi-agent message transport architecture based on the message-oriented middleware ZeroMQ. Compared with the other middlewares such as CORBA, Ice, and Thrift, ZeroMQ receives a good score in the evaluation of performance, QoS (Quality of Service), patterns, user friendliness, and resources. The suggested message transfer architecture borrowed many basic concepts like agent platform, AMS (Agent Management System), and MTS (Message Transfer System) from FIPA (Foundation for Intelligent Physical Agents) standard multi-agent specifications, and the architecture inherited the strength of the architecture from the multi-agent framework SMAF (Smart Multi-Agent Framework). The architecture suggested in this paper is a novel peer-to-peer architecture which is not known to the ZeroMQ community. In the suggested architecture, every MTS agent uses only one ZeroMQ router socket to support peer-to-peer communication among MTS agents. The suggested architecture can support closely collaborating software areas such as intelligent robots as well as the traditional application areas of multi-agent architecture. The suggested architecture has interoperability and scalability with the ZeroMQ devices and patterns.
