  • 최근 분산 시스템이나 협업 시스템을 위한 피어 투 피어(Peer-to-Peer) 네트워크에 대한 연구가 진행되고 있으며 암호학 분야에서는 pairing을 이용한 ID 기반의 공개키 암호 기법에 대한 연구가 활발히 이루어지고 있다. 본 논문에서는 동적 피어 그룹(Dynamic Peer Group, DPG) 멤버간의 안전한 그룹통신을 위한 ID 기반의 그룹키 관리 기법을 제안한다. 각 멤버들은 Private Key Generator(PKG)로부터 자신의 ID에 대한 공개키/개인키쌍을 발급 받으나, 그룹키를 관리하기 위한 중앙 관리개체를 이용하지 않고 멤버들간의 협력(collaboration)을 통해 자발적으로 그룹키를 관리함으로써 중앙 관리개체의 오류에 대한 문제(single-point of failure)를 예방할 수 있다. 그리고 동적 피어 그룹의 성질을 고려하여 멤버의 참여와 탈퇴에 대한 그룹키의 비밀성을 제공한다.

  • This study aimed at examining an effect of peer counselor's mentor activity on rejected children's peer relationship in elementary school. To achieve this goal, the following hypothesis was made. Hypothesis I : Peer counselor's mentor activity will improve rejected children's peer relationship. I -1 : Peer counselor's mentor activity will improve rejected children's trust to peer. I -2 : Peer counselor's mentor activity will improve rejected children's respect to peer. To test the hypothesis, after sociometry papers 19 fifth-graders for rejected children groups were selected from four classes at H elementary school in Busan according to Coie & Dodge's(1988) five classified system that is modified to Korean situation by Ahn ie-hwan(2006). Ten rejected students from two classes were labeled as a peer group with a peer counselor and nine rejected students who had similar characteristics from two classes were labeled as an non-peer group without a peer counselor. The peer counselors were decided by obtaining affirmative mentions of rejected students group. Peer counselors participated in the training of peer counselor's skill program and then they had a person to person mentor activity with the rejected children's group that they belonging to. The training consisting of a total of four sessions, 3 times a week, was provided to peer counselors eleven times after school. The peer counselors given the peer counselling training did person to person mentor activity with the peer group's rejected children for a month. The mentor activity, three times a week, following during training was reinforced after school. For peer counselor training, the elementary school children's peer counseling program developed by Lee Sang-hi, Roh Seong-deok and Lee Ji-eun(2001) was used. Hong Ok-soon's(1984) peer relationship test, Moreno's(1934) sociometry tool were used to verify an effect of the peer counselor's mentor activity. For the data analysis, quantitative analysis with sociometry tool and qualitative analysis with social status and social type change were used. To know the difference in pre test and post test peer relationship between experimental group and control group, in quantitative analysis, ANCOVA result was used and qualitative analysis, social status and social type was used. The finding was as followings. First, after peer counselor's mentor activity, there was a significant improvement in rejected children's trust and respect to peer and the whole relationship from the pretest to the post test. Second, peer counselor's mentor activity gave rise to affirmative changes on rejected children's social status and social type. This study concluded that peer counselor's mentor activity would help rejected children's peer relationship to change affirmatively and improve.

  • This study aimed to investigate effects of peer feedback types and feedback acceptance levels on academic achievement in project-based learning. The participants were 70 middle-school students taking an English course. They were divided into corrective and suggestive feedback groups. These participants were asked to create user-created content (UCC) as an individual task and provide peer feedback on a peer's UCC in the same type of feedback group. Results showed that there were significant differences in academic achievement according to peer feedback types (corrective vs. suggestive) and feedback acceptance levels (high vs. low). In particular, the suggestive peer feedback group had higher academic achievement than the corrective peer feedback group. Moreover, the group with a high level of feedback acceptance gained higher academic achievement than the group with a low level of feedback acceptance. Moreover, there was an interaction effect between peer feedback types and feedback acceptance on academic achievement. These results indicate that peer feedback types and feedback acceptance should be considered for effective peer feedback activity. These findings provide practical implications for the design and implementation of peer feedback activity in project-based learning.

  • Purpose: This study was conducted to identify the influence of nurse manager and peer group caring behaviors as perceived by nurses on intention to retention. Methods: The participants for this study were 229 nurses who had worked for over 6 months in general hospitals located in J province. Survey data were analyzed descriptive statistics and t-tests, ANOVAs with $Scheff{\acute{e}}^{\prime}s$ post-hoc testing, Pearson's correlation coefficients, and hierarchical regression analysis. Results: The scores for 'manager and peer group caring behaviors' and intention to retention were all at a moderate level, although the subjects perceived 'peer group caring behaviors' as higher compared to 'manager caring behaviors'. There were significant differences in 'manager caring behaviors' scores by suitability for present working department and employment status and in 'peer group caring behaviors' scores by suitability for present working department. The factors influencing nurses' intention to retention were religion, suitability for present department, clinical experience of over ten years, 'manager caring behaviors', and 'peer group caring behaviors' Conclusion: To improve nurses' intention to retention, it may be necessary to alter the transfer and arrangement strategies of their working environments to better consider nurses' aptitude and competence, and thereby increase both manager and peer group caring behaviors.

  • This review of the literature explored the experiences and effects of peer-assisted learning in basic medical education. Peer-assisted learning is most commonly utilized to teach clinical skills (including technical skills) and medical knowledge (76.4%). It has also been used, albeit less frequently, to facilitate small-group discussions including problem-based learning, to promote students' personal and professional development, to provide mentoring for career development and adaptation to school, to give tutoring to at-risk students, and to implement work-based learning in clinical settings. Near-peer learning is a common type. The use of active learning techniques and digital technology has been increasingly reported. Students' leadership had frequently been described. Student tutor training, programs for teaching skills, institutional support, and assessments have been conducted for effective peer-assisted learning. There is considerable positive evidence that peer-assisted learning is effective in teaching simple clinical skills and medical knowledge for tutees. However, its effects on complex skills and knowledge, small-group discussions, personal and professional development, peer mentoring, and work-based learning have rarely been studied. Additionally, little evidence exists regarding whether peer-assisted learning is effective for student tutors. Further research is needed to develop peer-assisted learning programs and to investigate their learning effects on student tutors, small-group discussion facilitation, personal and professional development, peer mentoring, and peer-led work-based learning in the clinical setting in South Korea. Formal programs and system advancement for a student-led learning culture is needed for effective peer-assisted learning.
