Given the increasing information overload among users of online review websites, understanding the manner in which cognitive costs are reduced and efficient information is made reliable has become increasingly important. This study targets a unique consumer review design and explores how reviews from an external peer-to-peer site embedded in an online travel agency (OTA) website influence subsequent evaluation behaviors. The empirical results indicate that (1) embedded external reviews with a high average valence tend to strengthen the influence of the positive evaluation ratio while diminishing the effect of the review volume, and (2) embedded external reviews with a large variance strengthen the positive effect of the review volume while weakening the effect of the positive evaluation ratio on subsequent positive evaluations. The findings provide practical insights for consumers and online platforms.

최근 소셜미디어의 대중화와 함께 소셜러닝에 대한 관심이 높아지고 있다. 소셜러닝의 긍정적 학습효과에 대한 기대에도 불구하고 교실수업 환경에서 소셜러닝의 구체적인 적용 방법과 그에 따른 학습 향상의 명시적 효과에 대하여서는 아직도 알려진 사례가 많지 않은 실정이다. 본 연구에서는 교실수업 환경에서 웹 기반의 과제 상호 평가를 통하여 개별 학습자들 간의 특정 주제에 대한 생각 공유가 발생하도록 하고, 그러한 상호 생각 공유가 개별 학생의 지식 구성에 어떤 영향을 주었는지를 살펴보았다. 수행된 실험결과에 따르면 학습자들은 다른 학습자들과의 생각의 공유를 통하여 지식이 결합 혹은 재조합되어 자신의 지식 구성에 영향을 주고 있음을 알 수 있었다. 이 실험 결과는 소셜러닝의 효과성에 대한 중요한 시사점을 줄 수 있을 것이다.

동료평가란 학생들이 다른 학생의 글, 발표, 집단 활동과 같은 평가 대상이 될 수 있는 모든 결과물이나 수행 과정에 대해 점수를 매기거나 의견을 제공하는 활동을 가리킨다. 동료평가는 채점부담으로 인해 잘 활용되지 않는 글쓰기 기회를 늘릴 수 있을 뿐만 아니라, 평가를 하는 과정을 통해 학습도 향상시킬 수 있다는 장점이 있다. 본 개관 논문에서는, 주요 동료평가 시스템과 동료평가를 사용한 경험적 연구 결과를 소개한 다음, 동료평가 확산의 장애 요인을 살펴보고, 앞으로의 연구에서 해결되어야 할 과제가 논의되었다. 이 논의를 통해 동료평가에 대한 후속 연구가 활성화되고 동료평가가 실제 교육 장면에서 활용되어, 우리나라의 평가와 수업 방법에 큰 변화를 가져오기를 기대해본다.

The capstone design classes in the College of Engineering are often team project-oriented, and teamwork skills are reported to positively impact problem-solving abilities. While team project courses have various advantages, they also come with challenges such as social loafing and issues related to free riders, which consistently hinder the positive effects of team project courses. To prevent these issues, there is a need to provide a clear evaluation-reward system for team members' contributions. In this study, we examined the reliability of peer evaluation scores for team members' contributions and reviewed methods to incorporate them into team project grades. The review results indicated that peer evaluation scores are deemed to have considerable reliability from a qualitative perspective. However, due to the relatively small team size in team project courses (3 to 6 members per team), using the arithmetic mean of peer evaluation scores is statistically challenging. As a complementary approach, this study proposes limiting the reflection ratio of peer evaluation scores and applying a more macroscopic processing method, not the arithmetic mean, to incorporate peer evaluation scores for team contributions into grades.

Peer-to-peer(P2P) has potential strength and possible factors which enable it to develop toward a new business by supplementing the limitation of the existing central server-type network. In various business sectors, various attempts have already been made to apply P2P. The computing power which was possible to be formed through peer-to-peer networking will become a powerful tools for expanding toward new business area depending the utilization methods by sector. Although the technology-centric P2P concept is a major interest now, its development direction will head toward service-centric P2P concept for satisfying desires of end-users(individual peers) for reliable contents and improving their purchasing convenience. But the solution requisites should be solved for the efficient application of P2P to business such as the establishment of and supplement for the industrial standard and legal system for P2P, the enhancement of peers recognition of P2P. Presently e-commerce using P2P is being implemented by a few enterprises locally by means of B2C. But if many enterprises enter this type of e-commerce, and the standardization of peer programmes, goods and documents is made, it will be able to be extended to B2B. Also it seems that it can be utilized in international transactions as well as in domestic transactions. So there is much room for the application of P2P to be extended further. Also there has been presented the necessity for related industries to support their work with theories and for academic studies to be made actively to set the direction of its development. It is hoped that multi-angled and in-depth studies on the utilization of P2P and various attempts to application of it to business be made on the basis of this study. For the development of P2P, continuous study and attempts are needed. The field of P2Ps application is very large and it will become a powerful tool, depending upon its application methods.

Based on ASME probabilistic risk assessment (PRA) and NEI PRA peer review guidance, we evaluate a human reliability analysis (HRA) in probabilistic safety assessment (PSA) for Korea standard nuclear power plants, Ulchin Unit 3&4, to improve it performed at under design. The HRA for Ulchin Unit 3&4 is assessed as higher than Grade I based on ASME PRA standard and as higher than Grade 2 based on NEI PRA peer review guidance. The major items to be improved identified through the evaluation process are the documentation, the systematic human reliability analysis, the participitation of operators in the works and review of HRA. We suggest the guidance on the identification and qualitative screening analysis for pre-accident human errors and solve some items to be improved using the suggested guidance.

For evaluating participation in collaboration project, the peer assement method is mostly used and various scoring methods have been proposed. But, the reliability and validity of the peer assessment method are still doubted for all most method. In order to overcome these weaknesss, some guidelines and training methods have been recommended. In this article, however, statistical technique is proposed for measuring individual contributions to collaboration projects considering each assessor's reliability. The gist of our proposed algorithm is that an assessor's reliability depends on the evaluation policy, and this reliability is evaluated by an analysis of variance of the scores assigned by the assessor. We also show that the proposed method is very efficient by case study in university class.

본 연구는 중등 예비음악교사들을 대상으로 동료멘토링을 활용하여 Bandura의 사회학습이론의 자기효능감 요인들 즉, 상황경험, 간접경험, 언어적/사회적 설득, 감성적/생리학적 상태의 향상과 동료멘토링 인식에 관한 연구이다. 이를 위해 멘토와 멘티로 구성된 팀활동과 멘티의 수업시연 및 동료평가를 실시하였으며, 교사로서의 자기효능감 향상에 대한 결과를 확인하기 위해 인터뷰와 성찰저널을 세부적으로 분석하였다. 그 결과 교사로서의 자기효능감 요인들이 향상된 것을 확인할 수 있었다. 동료멘토링의 인식에 대한 결과 분석에서 멘티의 경우 멘토들의 조언을 통해 상호작용과 소통을 통해 다양한 도움을 받을 수 있었다는 긍정적인 변화를 확인할 수 있었다. 이러한 결과를 바탕으로 향후 예비음악교사들의 교사로서의 자기효능감 향상을 위해 다양한 교수법을 활용한 교육실습 및 실무경험의 기회가 요구되는 것으로 분석되었다.
