This study investigated cross-informant measures of peer group victimization. The subjects were 460 children in the fifth and sixth grades. Children completed questionnaires that assessed their own victimization feelings of loneliness, and self-perception. They also completed peer nominations concerning peer acceptance and rejection. The results suggest that self-reported victimization is more predictive of loneliness and self-perception, whereas victimization from peer nominations is more predictive of peer rejection and acceptance.

The present study purposed to examine adolescents' peer relation quality, and school life maladjustment according to the characteristic of their mobile phone use and their mobile phone addiction. The subjects of this study were 490 middle/high school students in Namyangju City. A survey was conducted using a self reporting questionnaire, and collected data were analyzed with SPSS 12.0. The results are as follows. First, mobile phone use was different according to gender, school year and the degree of mobile phone addiction. Second, the addiction group was 12.9% of the subjects, the dependent group was 52.7%, and the non addiction group and 34.5%. Third, in the addiction group, the negative factors of peer relation quality were significantly higher than the positive factors of peer relation quality. Fourth, in the addiction group, all the factors of school life maladjustment were significantly high. Fifth, school life maladjustment was higher when the degree of mobile phone addiction was high and when the negative factors of peer relation quality were high. This suggests the necessity for education on the right use of the mobile phone and mobile phone addiction treatment program; in order to improve adolescents' peer relation quality and ease their school life maladjustment. The results of this study are expected to be useful in developing effective interventions for adolescents' healthy growth.

This study examined different individual and environmental factors that affect children's game addiction tendency. As individual variables, game user' motivation, self-control, and self-esteem were included in the analysis. As family variables, communications with mothers, parental control of children's computer use and parental internet use were examined, as school variables, school adjustment and teacher's supervision of children's computer use, and as peer variables, peer group's attitude toward computer games were used. The sample consisted of 994 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, two way ANOVA, Pearson's correlation and Hierarchical Regression. Several major results were found from the analysis. First, boys were addicted more than girls. No difference was found in the addiction tendency between the 5th graders and the 6th graders. Second, game users' motivation, that is, their interest-amusement motive, avoidance motive and aggressive motive, had a positive correlation with their game addiction tendency. However, self-control and self-esteem had a negative correlation with children's game addiction tendency. Third, problematic communications with mothers and parental control of children's computer use had a positive correlation with children's game addiction tendency. Open communications with mothers had a negative correlation with children's game addiction tendency. Fourth, school adjusaent had a negative correlation with children's game addiction tendency. And peer group's attitude towards computer games had a positive correlation with children's game addiction tendency. Fifth, low self-control, peer group's attitude towards computer games, children's interest-amusement motive, avoidance motive, aggressive motive, school lesson adjustment, parental control of children's computer use and school nile adjustment were important predicting variables of boy's game addiction tendency. Avoidance motive, low self-control, interest-amusement motive, peer group's attitude towards computer games, and parental control of children's computer use were important predicting variables of girl's game addiction tendency.

Background : This study was to reduce incidence of falls by analyzing actual problem and drawing out improvement plan applicable to the clinical practice through operation of the staff nurses-centered fall peer review group. Method : The fall peer review group was composed of 8 nurses having patient nursing experience for over 5 years, and each of fall cases was reviewed and the root cause was analyzed. As a result, it was found that the patients and their families did not fully understandthe content of the education, and the staff nurses did not completely inspect the risk factors of falls and perform immediate intervention when patient's condition changed. Based on the above-mentioned results, improvement activity was conducted for the purposes of consolidating patients education method and supplementing computerized system to support nurses' decision making as well as devices and facilities. Result : As a result of conducting improvement activity in the aspects of education for patients, support of nurse's decision-making, and devices and facilities through operation of the staff nurses-centered fall peer review group, falls decreased by 9.5% compared to before improvement activity. Conclusion : It is concluded that operation of the clinical nurses-centered fall peer review group played a role of promoter to draw out practical and applicable improvement plan to the clinical practice and apply directions of the field-centered, and increased nurses' interest in falls and ultimately, reduced incidence of falls. Therefore the Center will continue to operate the staff nurses-centered peer review group, and recommends participation of nurses who actually take the charge of nursing patients in further analysis of patients' safety accidents.

고차적 사고를 요구하는 글쓰기는 배운 지식을 활용하고 발전시키게 한다. 학습 장면에서 글쓰기를 더 많이 활용하기 위해서는 동료평가를 도입하는 동시에 동료평가의 정확도를 높일 필요가 있다. 본 연구에서는 동료평가의 정확도를 높이는 방안으로, 평가 기준에 대해 학생들끼리 토론하게 하거나 전문가의 평가를 참고하도록 하는 두 방안을 탐색하였다. 대학생 150명을 대상으로 한 실험 결과, 동료평가 후 전문가의 평가를 참고했던 집단이 평가했던 글을 다시 평가할 때는 평가 정확도가 향상되었지만, 새로운 글을 평가할 때는 향상되지 않았다. 반면에, 동료평가 후 평가 기준에 대하여 토론을 진행했던 집단은 평가했던 글을 다시 평가할 때는 평가 정확도가 향상되지 않았지만, 새로운 글을 평가할 때는 향상됨을 발견하였다. 또한 토론 집단의 경우 평가 기준에 대한 토론에서 총 발언 수가 많아질수록 평가 정확도가 높아졌다. 이상의 결과는 평가 기준에 대한 토론에서 적극적이고 자발적인 논의가 활발할수록 이후 동료평가의 정확도가 향상됨을 시사한다.

The hybrid architecture of content delivery networks (CDN) and peer-to-peer overlay networks (P2P) is a promising technology enables effective real-time streaming services. It complements the advantages of quality control and reliability in a CDN, and the scalability of a P2P system. With real-time streaming services, however, high connection setup and media delivery latency are becoming the critical issues in deploying the CDN-P2P system. These issues result from biased peer selection without location awareness or content awareness, and can lead to significant service disruption. To reduce service disruption latency, we propose a group-based CDN-P2P hybrid architecture (iCDN-P2P) with a location/content-aware selection of peers. Specifically, a SuperPeer network makes a location-aware peer selection by employing a content addressable network (CAN) to distribute channel information. It also manages peers with content awareness, forming a group of peers with the same channel as the sub-overlay. Through a performance evaluation, we show that the proposed architecture outperforms the original CDN-P2P hybrid architecture in terms of connection setup delay and media delivery time.
