본 연구는 문제중심학습에서 튜터, 동료, 자기평가간의 평가점수를 비교하고 평가주체 점수간의 관련성과 평가주체별로 평가에 영향을 미치는 평가영역을 알아보는데 목적이 있다. 이를 위해 문제중심학습으로 수업받는 간호학과 학생 105명을 대상으로 문제중심학습 효과도구를 가지고 3차에 걸쳐 튜터, 동료, 자기평가를 실시하였다. 수집된 자료는 SPSS WIN(V. 12.0)으로 분석하였다. 연구결과 3차례의 수업 모두 자기평가 점수가 튜터, 동료평가 점수보다 높았다. 평가주체별 점수간의 관계는 3차례의 수업에서 튜터평가와 동료평가간에 관련성이 있었다. 평가주체별 평가에 영향을 미치는 평가영역은 튜터평가는 '문제해결능력'이었고, 동료평가와 자기평가는 '협동학습능력'이었다.

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 is to investigate the effects of peer-to-peer relay feedback strategy on achievement in mathematical problem solving and mathematical communication ability. The experimental instruction was given to 99 students. They were divided into two groups. In this research a strategy of peer-to-peer relay feedback is developed. To enhance lateral communication, students were instructed according to the strategy to read open-type problems, to write mathematical ideas individually and to share their ideas and get feedback in relay method with peers within a small subgroup. The results are as follows. 1) Mathematics achievement assessments were carried six times in the cleanup phases of the class. There was no difference at the 1st test. 2) The second t-test of mathematical communication abilities showed that there was meaningful difference and that peer-to-peer relay feedback was effective. But there was no difference on reading. 3) Peer-to-peer relay feedback strategy has a positive impact.

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.

멀티미디어 스트리밍에서 유니캐스트 방식은 사용자 수가 증가함에 따라 트래픽이 증가하게 되어 추가적인 비용 부담이 있게 된다. 멀티캐스트 방식은 이러한 문제점을 해결할 수 있으나 클라이언트의 접속과 제어정보를 가질 수 없으며, 현재 대부분 라우터들이 유니캐스트 방식만을 지원하고 있는 실정이다. 또한, 다른 ISP 사업자간에는 서비스를 받을 수 없는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 극복하기 위해 원격 화상교육을 위한 유니캐스트 방식과 P2P를 응용한 트래픽 에이전트 시스템을 제안하였다. 제안된 시스템은 컨트를 에이전트에 의해 스트림 서버의 트래픽이 감소되고,네트워크의 비용을 줄일 수 있다. 이 시스템은 JMF와 응용 소프트웨어를 이용하여 원격 화상교육을 시연함으로써 본 시스템의 타당성을 검증하고 분석하였다.

This study examines the effects of reflective journal writing on the mathematics self-efficacy in reciprocal peer tutoring. Participants were 38 high school students in Gyeonggi province who attended at a summer intensive mathematics course for 4 weeks. This study used a mixed method. SPSS 21.0 program was used to analyze the quantitative data, and the interviews, observational journals and reflective journals of 6 students were used to analyze qualitative data. According to the results, all the subcategories of mathematics self-efficacy, - mathematics problem-efficacy, mathematics success-efficacy, mathematics learning-efficacy, and mathematics subject-efficacy - improved except mathematics occupation-efficacy. In case of mathematics success-efficacy and mathematics problem-efficacy, students revealed the greatest improvement. In conclusion, reflective journal writing in reciprocal peer tutoring could be suggested as a treatment program to improve students' mathematics self-efficacy.

유비쿼터스 환경에서는 다양한 서비스를 구매하기 위한 지불 시스템이 필요하며, 빈번한 거래에 지불 처리 비용을 최소화하는 소액 지불 시스템이 요구되고 있다. 또한 장치가 계속적으로 온라인임을 보장할 수 없기 때문에 그 중 일부가 오프라인인 경우에도 사용할 수 있는 지불 시스템이 요구된다. 이러한 상황을 해결하기 위해 다른 시스템은 중앙의 브로커를 사용하는데, 대부분의 소액 지불 시스템의 문제는 브로커에 부하가 집중된다는 것이다. 본 논문에서는 유비쿼터스 환경을 위한 분산 해시 테이블 기반의 Peer-to-Peer 소액 지불 시스템을 이용해 온라인이 아니어도 지불할 수 있고, 브로커의 부하를 최소화하는 지불 시스템을 제안한다.

The present study examined differences in children's behavior problems and peer interaction, and parental factors including self-esteem, depression and childrearing stress between atopic dermatitis(AD) and normal(non-AD) children in each gender, and analyzed the effects of the parental factors on the two variables of AD children. 165 AD and 1176 non-AD children of age 5 were selected from the 6th year data of the Panel Study on Korean Children. The results from t-test and multiple regression are as follows. First, only AD boys showed a higher level of behavior problems than non-AD boys, but peer interaction showed no difference between AD and non-AD groups. Compared with non-AD children's parents, mothers of AD children showed a higher stress level and mothers of AD boys had a higher depression level. But there were no differences in maternal self-esteem and paternal factors between the groups. Second, AD boys' behavior problems were related to maternal factors and paternal stress, and some characteristics of AD girls' behavior problems were related with some parental variables. But peer interaction of AD children had no relation with parental factors. Third, behavior problems were influenced by maternal stress in AD boys and influenced by maternal depression and parental self-esteem in AD girls.

The purpose of this study was to identify relationships among peer pressure, parental supervision, alcohol expectancy and adolescent drinking behaviors between year 2001 and 2006. Three hundred high school students were given questionnaires each year on their drinking behavior. Findings of this study were; first, a adolescent drinking and the amount drinking has increased during the years. adolescent drinker ratio as adolescent drinkers were 91.3% in 2006 compared to 75.9% in 2001. The average drinking amounts were 40.82 units in 2006 and 24.9 units in 2001. Second, differences were found in adolescent drinking behaviors such as the amount of alcohol consumption, drinking frequency, & problem drinker ratio by gender, and grade. Male students over female students. Third, peer pressure, parental supervision, alcohol expectancy showed significant impacts on adolescent drinking behaviors through 2001 and 2006. Students who lack parental supervision with much higher drinking-related peer pressure along with a higher level of positive alcohol expectancy were observed to be heavy drinkers and problem drinkers. Especially, students who showed belief in alcohol's tension-relieving function and sociability function tended to over-drink, drink more frequently and as a result, experienced more drinking problems. Intervention strategies were discussed.
