Reputation systems aggregate users' feedback after the completion of a transaction and compute the "reputation" of products, services, or providers, which can assist other users in decision-making in the future. With the rapid growth of online e-Learning content providing services, a suitable reputation system for more credible e-Learning content delivery has become important and is essential if educational content providers are to remain competitive. Most existing reputation systems focus on generating ratings only for user reputation; they fail to consider the reputations of products or services(item reputation). However, it is essential for B2C e-Learning services to have a reliable reputation rating mechanism for items since they offer guidance for decision-making by presenting the ranks or ratings of e-Learning content items. To overcome this problem, we propose a novel collaborative filtering based reputation rating method. Collaborative filtering, one of the most successful recommendation methods, can be used to improve a reputation system. In this method, dual information sources are formed with groups of co-oriented users and expert users and to adapt it to the reputation rating mechanism. We have evaluated its performance experimentally by comparing various reputation systems.

This study was to evaluate the quality of academic information services provided by Naver Academic Information Service, Google Scholar, and MS Academic Search. This academic information services were evaluated in terms of the contents, service, and effectiveness. 135 four year college students were recruited for the survey. The results showed that the Google Scholar in contents section had higher score than Naver and MS Academic Search. In regard to service, Google Scholar had higher score in retrieval section while Naver had higher score in design section respectively. Finally, both Google Scholar and Naver in the access section had higher score than MS Academic Search.

손상된 조직이나 부위를 원상태로 회복하기 위한 대제 물질인 생체재료 개발에 관한 연구가 꾸준히 이루어지고 있다. 이러한 생체재료는 생체내에서 기능을 수행하기 위한 기계적 특성과 생물학적 특성을 갖추어야 한다. 생분해성 고분자는 금속재료에 비해 우수한 분해성으로 널리 사용되고 있다. 그러나 대부분의 생분해성 고분자는 약한 기계적 특성으로 사용범위가 제한적이다. 문제점의 해결을 위해 hydroxyapatie와 TCP등을 활용한 방법이 제시되어왔다. 이에 본 연구는 ${\beta}-TCP$ 첨가량에 따른 세라믹/고분자 복합체를 제조하여 다양한 기계적 효과를 평가하였다.

The purpose of this study is to look into the effect of wearing color lenses on one's image and was based on 221 college students in Gyeonggi-do and Gangwon-do. I examined how it appears as the evaluation factor visually. After by looking in the different image effect and relevance as to the classified evaluating factors, I tried to look into what effect the color lenses has on woman eye and image. The result is as follows. It appears that wearing color lenses makes one look fancier, more attractive, sophisticated, and favorable, whereas not wearing color lenses makes one look softer, weaker, more innocent, and comfortable. Analyzing these evaluations showed that wearing color lenses has most to do with attractiveness followed by pureness, familiarity, and decorativeness in order, whereas not wearing color lenses has most to do with familiarity followed by attractiveness, pureness, and decorativeness. It is considered that eyes with color lenses on them make the person seem decorative, attractive, and pure, which brings effect of improving one's eye and face image. Analyzing the correlation between each color lenses-wearing factor and one's image showed that when a person is wearing color lenses, the more the person is considered decorative, pure, and attractive, the more it has to do with improving the person's eye and face image. The result, therefore, shows that wearing color lenses makes one's eye and face image attractive, pure, and decorative, and wearing them is an important means to improve one's eye and face image.

마이크로티칭은 교사들의 모의수업을 녹화한 후 피드백, 평가, 성찰의 과정을 통하여 수업 스킬을 개선하는 교수-학습방법으로 교직수업 및 교원연수 등에 활용되고 있다. 그러나 마이크로티칭을 진행하는 데에는 상당한 시간적, 물리적 부담이 부가되며, 때문에 더욱 의미있는 학습, 평가와 성찰의 기회가 허락되지 않기도 한다. 따라서 이를 효율적, 효과적으로 지원할 수 있는 방안이 모색되어야 한다는 요구가 있다. 본 연구에서는 동영상 위키 시스템에 기반을 둔 마이크로티칭 지원도구를 개발하였다. 이 시스템은 텍스트, 음성 기반 피드백 기능을 지원하여 교수자의 피드백을 보다 원활하게 도우며, 동영상 위키의 속성을 활용하여 동료피드백을 지원하여 능동적 상호작용이 이루어질 수 있다.

Development and implementation of virtual training contents has been increasing along with the emphasis on the experience and practice in engineering education. Virtual training makes repeatable sessions possible within safe learning environment which is very similar with real work place. This feature is very helpful to learners when they manipulate real machines back at work after studying with the virtual training content. The purpose of this study is to develop "Total Station and GPSS surveying" virtual training content focusing on both theory and surveying practice within various circumstances and to explore learners experience. Results show high interest, immersion, perceived learning effectiveness, and satisfaction to the content.
