The purpose of this research was to investigate the possibility of peer recommendation and to provide a diverse perspectives identifying for gifted elementary school students. The subjects were 355 elementary school students who were either fourth, fifth, and sixth grade from D elementary school located in Gyeonggi province, 165 elementary school students who are either fourth, fifth, and sixth grade from J elementary school located in Gyeonggi province, and 16 teachers who were home-room teachers for students surveyed. This research investigate the difference of creative personality, achievement motivation, problem solving patterns, and task preference inventory between students recommended by peer and students not recommended by peer. The results of this research were as follows. Firstly, the students recommended by peer showed the significantly higher creative personality, achievement motivation, problem solving patterns, and task preference than the student not recommended by peer. Secondly, as a result of comparing the students recommended by peer and students not recommended by peer for each grade, fifth and sixth grade students showed a significantly higher score in the test than other graders. Fourth grade students showed significantly higher score in every sections in the test, except for the section of creative personality. Therefore, the peer recommandation method can be applied to fifth, and sixth graders. Thirdly, the student recommended by both teacher and peer showed significantly higher problem solving patterns, and task preference scores than the student recommended only by teacher. Therefore, peer recommendation method can be an useful data for complementing teacher recommendation and it can identify gifted elementary school students.

Objectives: This study was performed to examined the effectiveness evaluation of peer education program on smoking prevention and cessation for elementary school students. Methods: Data were collected from 60 students in a rural area through self-administrated questionnaires. Child-leaders participated the peer education program to assist their friend, parent, and adult in community to quit the smoking for 4 weeks. Results and Conclusions: Major conclusions were as follows : 1. The peer education program on smoking prevention and cessation for elementary school students was reinforce to increasing the tobacco knowledge and the cessation skill, learning the communication skill, and improving the empowerment. 2. Image of tobacco, intention of smoking in future, recommendation for smoking cessation, pro of smoking. con of smoking, and level of assert in post-test were higher than those in pre-test. 3. There were significant differences in image of tobacco, con of smoking, and level of assert by grade between the pre-test and the post-test of peer education program. But intention of smoking in future, recommendation for smoking cessation, and pro of smoking were not related to effectiveness of peer education program. 4. Child-leaders for smoking prevention and cessation performed the their task to 1.4 persons per student. 5. Participating students were satisfied with the contents of program, the usefulness of educational materials, and preference of parents, but they were not satisfied with the usefulness of task note, learning time, and lecture room.

In this paper, we propose a new P2P-based music recommendation system. In comparison with previous system in client-server environment, the proposed system shows higher quality of music recommendation through real-time sharing of music preference information between peers. A collaborative filtering is implemented as a recommendation algorithm. As a user preference profile, we use the inherit KID music genre index contained in all legitimate music file instead of music feature vectors as in previous research so that the proposed system can mitigate the performance degradation and high computational load caused by feature inaccuracy and feature extraction. The performance of the proposed system is evaluated in various ways with real 16-weeks transaction data provided by Korean music portal, 5 company and it shows comparative quality of recommendation with only small amount of computational load.

A various multimedia application services are developed wiht techniques of high speed networks and computer. Especially the videoconference system is important and useful in a remote discussion with multiple users. A vidoconferencing system in local area network used in corporation and university is useful and important. A standardization for it should be showed in ITU. Recommendation H.323 describes terminals, equipment, and services for videoconference over communication networks which do not provide a guaranteed Quality of Services for videoconference over communication networks which do not provide a guaranteed Quality of Service. In this paper, we introduce ITU-T H.323 which is the standardization over internet, and show a multipoint videoconferencing system and peer to peer videophone system using the ITU-T H.323.

News contents has been collected, selected, edited and sometimes distorted by the news recommendation mechanisms of online portals in nowadays. Prior studies had not confirmed the consensus of newsworthiness, and they had not tried to empirically validate the impacts of newsworthiness on audience reactions. This study challenged to summarize the concepts of newsworthiness and validate the impact of representativeness of both editor's and audience's perspective on audience reactions as perceived news quality, trust on news portal, perceived usefulness, service satisfaction, loyalty, continuous usage intention, and word-of-mouth intention by adopting the representativeness heuristics method and information adoption model. 357 valid data had been collected using a scenario survey method. Subjects in each groups are exposed by 3 news recommendation mechanisms: 1) the time-priority news exposure mechanism (control group), 2) the reference-score-based news recommendation mechanism (a single treatment group), and 3) the major-news-priority exposure mechanism sorting by the reference scores made by peer audiences (the mixed treatment group). Data had been analyzed by the MANOVA and PLS method. MANOVA results indicate that only mixed method of both editor and audience recommendation mechanisms impacts on perceived news quality and trust. PLS results indicate that perceived news quality and trust could significantly affect on the perceived usefulness, service satisfaction, loyalty, continuance usage, and word-of-mouth intention. This study would contributions to empathize the role of information technology in media industry, to conceptualize the news value in the balanced views of both editors and audiences, and to empirically validate the benefits of news recommendation mechanisms in academy. For practice, the results of this study suggest that online news portals would be better to make mixed news recommendation mechanisms to attract audiences.

Finding and selecting proper reviewers is a burden on the publisher of the journal. In order to solve this problem, the online submission system started to recommend appropriate reviewers automatically. It includes a variety of new features, from recommending authors in the references of submitted papers as reviewers to finding similar papers by searching the citation index and suggesting reviewer candidates extensively. This study investigated how the online submission system provides functions such as recommendation of reviewers. As a result of examining major online submission systems, ScholarOne and Editorial Manager were recommending reviewer candidates by commercial citation index and review history platform. On the other hand, JAMS, a domestic online submission system, did not have any advanced functions such as recommendation of candidates for reviewers. Sooner or later, in Korea, it seems that more efforts should be made to improve the function of online submission system, such as recommending suitable reviewers for papers.

최근 P2P 모델을 기반으로 한 애플리케이션의 등장으로 다양한 자원을 효율적으로 이용할 수 있게 되었다. P2P에서는 여러 대의 클라이언트를 상호 긴밀하게 연결함으로써 한 대의 서버에 다수의 클라이언트를 연결했을 때 보다 확실한 네트워크의 효과를 기대할 수 있다. 그러나, 기존의 P2P 모델의 경우, 다수의 피어가 네트워크에 참여하여 방대한 양의 자원을 공유할 경우, 원하는 자원을 검색하는데 많은 시간이 소요되는 문제점이 있다. 본 논문에서는 자원 검색의 비효율적인 문제를 해결하고자 협력 필터링 알고리즘을 이용해 P2P 파일 추천 시스템을 제안하고자 한다. 제안한 P2P 시스템은 피어(Peer)들을 유사한 패턴을 갖는 가상 그룹으로 형성해, 그룹 내에서 유용한 자원들을 검색 없이 공유할 수 있도록 하였으며, 자원의 선호도를 기반으로 요청한 자원 외에 추천 시스템을 통해 선호하는 자원을 예측해 제공할 수 있도록 하였다.
