Objective: This study examined the association between mother-child communication and preschool children's peer competence mediated by ego resiliency Methods: The data from 318 preschool age children and their mothers in Seoul and Gyung-Gi province were used for this study. Mothers reported mother-child communication using three subscales from the revised parent-child communication inventory(Barnes & Oslom, 1982). This study used four subscales from the Korea Personality Inventory for Children (KPI-C)in order to calculate children's ego resiliency and used six subscales from the Child Behavior Scales(Ladd & Profile, 1996). The data were analyzed using Multiple Regression in SPSS 19.0. Results: Positive mother-child communication predicted a higher level of children's ego resiliency and peer competence. Ego resiliency fully mediated the association between mother-child communication and prosocial competence, rejection against peers and insecurity. And positive mother-child communication predicted lower levels of children's aggression, dissociality and irritability. Its association was also mediated by ego resiliency. Conclusion/Implications: These findings indicated that a mother's positive communication with their child would enhance children's ego resiliency and peer competence in preschool children. Thus, the efforts to facilitate parents' positive communication skills in parent education can be promising for preschool children's positive development.

This paper deals with the peer-to-peer data communication to connect each distributed levels of developed unmanned system according to the JAUS. The JAUS is to support the acquisition of unmanned system by providing a mechanism for reducing system life-cycle costs. Each of distributed levels of the JAUS protocol divides into a system, some of subsystems, nodes and components/instances, each of which may be independent or interdependence. We have to distribute each of the levels because high performance is supported in order to create several sub-processor computing data in one processor with high CPU speed performance. To complement such disadvantage, we must think the concept that a distributed processing agrees with separating each of levels from the JAUS protocol. Therefore, each of distributed independent levels send data to another level and then it has to be able to process the received data in other levels. So, peer-to-peer communication has to control a data flow of distributed levels. In this research, we explain each of levels of the JAUS and peer-to-peer communication structure among the levels using our developed unmanned ground vehicle.

This study analyzed the effect of parent-child communication and peer relationship on children's internet addiction. The subjects were 642 elementary school students living in Daejeon city. Cronbach's $\alpha$, t-test, ANOVA, and Duncan's test were employed in analyzing the data by using SPSS 10.0. The findings of this study were as follows First, the boys were more addicted to internet use than the girls, as were the children of less educated parents. The children of parents with professional careers were less addicted to the internet. The children who perceived their school achievements as low were more addicted to the internet. Second, the children who spent more time daily, longer time at once and more frequently per weekly internet use were more addicted. Third, internet addiction was influenced tv parent-child communication and peer relationship. Boys who had more problem communications with their parents less open communication with their mother and a lower level of peer support were more addicted to the internet. The problem of communication with their mother and conflict in their peer relationship had more influence on the internet addiction of girls.

The purpose of this study was to analyze the effect of perceived parental neglect and abuse and peer attachment on school life adjustment according to children's gender. A total of 2,264 5th graders from the second Korea Child-Adolescent Panel Survey participated. The results were as follows: First, the boys had higher parental neglect and abuse scores than the girls, while the girls had higher peer attachment scores and higher school life adjustment scores than the boys. Second, every sub-element of school life adjustment was significantly negatively correlated with parental neglect and abuse regardless of the children's gender. Every sub-element of school life adjustment was significantly positively correlated with the 'communication' and 'trust' sub-elements of peer attachment regardless of the children's gender. In the case of the boys, the 'study activity' and 'peer relation' sub-elements of school life adjustment were significantly negatively correlated with the 'alienation' sub-element of peer attachment. For the girls, every sub-element of school life adjustment was significantly negatively correlated with the alienation sub-element of peer attachment. Finally, the factors of 'parental neglect and abuse', and the peer attachment sub-elements of 'communication', and 'trust' significantly predicted the boys' school life adjustment, while for girls, the significant predictors were 'parental neglect and abuse', 'communication', 'trust', and 'alienation'.

We overview the current distribution automation system in Korea and point out the limitations of the distribution services which can be provided by the current system. In this paper we propose a new distribution system architecture which is based on the peer-to-peer communication model. In this decentralized architecture the intelligent FRTUS can initiate data transmission without any interruption of a central server, and can exchange data with other FRTUS as peers. In order to support the peer-based distribution system, we specify the requirements for new communication network and suggest a way of improving the current distribution network where we adapt an intelligent module for protection and restoration, called MASX, and utilize the open communication network protocols. We also show how the new architecture can enhance major distribution services such as protection, automatic restoration, and equipment management.

As the wireless network technologies and the capability of the mobile terminals are evolving, advanced peer to peer applications for mobile users are attracting interests. In this paper, we propose the mobile P2P communication platform(MPCP) which provides transparency to the wireless network technologies and solutions to the limited resources of the mobile terminals. MPCP classifies the connection into two levels: a virtual channel and a session. A virtual channel is the network layer connection between the terminals whereas a session is the application layer connection. MPCP classifies the sessions into four types and applies different scheduling priority and data processing policies such as segmentation and reassembly. It selects proper wireless network technologies depending on the distance between the communication endpoints. To acquire dynamically changed access address, we harness the Session Initiation Protocol. We implemented MPCP on embedded Linux simulator and utilized the implementation in mobile P2P service development. For the quantitative analysis, we compared the performance of MPCP with that of ftp. Regardless of the number of simultaneous sessions, MPCP maintains the relative performance.

Mobile peer-to-peer (P2P) systems have recently got in the limelight of the research community that is striving to build efficient and effective mobile content addressable networks. Along this line of research, we propose a new peer-to-peer file sharing protocol suited to mobile ad hoc networks (MANET). The main ingredients of our protocol are network coding and mobility assisted data propagation, i.e., single-hop communication. We argue that network coding in combination with single-hop communication allows P2P file sharing systems in MANET to operate in a more efficient manner and helps the systems to deal with typical MANET issues such as dynamic topology and intermittent connectivity as well as various other issues that have been disregarded in previous MANET P2P researches such as addressing, node/user density, non-cooperativeness, and unreliable channel. Via simulation, we show that our P2P protocol based on network coding and single-hop communication allows shorter file downloading delays compared to an existing MANET P2P protocol.

This paper presents a realization of a peer-to-peer communication system for a UAV navigational monitoring using a commercial HSDPA(High Speed Download Packet Access) mobile communication device. The realized system consists of a communication server, an air data terminal and multiple ground monitoring devices, where the server transfers navigational data from a UAV to multiple monitoring devices in real-time with commercial HSDPA modem. Through ground and flight tests, data were obtained to observe the realized system. Test results show that, depending on communicational environment, about 300msec delay, congestion and packet-loss between air data terminal and ground monitoring devices. Nevertheless, through high-speed long range test on a ground vehicle and altitude test with a UAV flight, the feasibility of a UAV navigational monitoring system was observed.
