This paper deals with the design and implementation of interactive e-learning contents for OpenCourseWare. OpenCourseWare, also known as OCW began at MIT in October 2002. OCW is a free and open digital contents of high quality college and university level educational materials. In this paper, we have designed and implemented interactive e-learning contents for a regular course of introduction to java programing language and OCW of D University. We have developed a variety of multimedia elements, such as screen videos of practical exercise and animations in order to improve the effectiveness of learning. These e-learning contents are consist of interactive learning components that users can interact directly with. The e-learning contents developed in this study has been effectively applied to OCW and a regular course opened in the first semester of 2012.

The purpose of the study is to identify the accessibility of OpenCouresWare(OCW) from the perspective of college students with visual and hearing impairments. Six students with visual impairments(3 blind and 3 low vision) and four students with hearing impairments(2 deaf, 2 hard of hearing) implemented usability testing. Two modules in KOCW were selected for testing. Students implemented usability testing and then each individual case was analyzed through quantitative and qualitative methods. As results, the degree of usability and accessibility in two modules indicated low level. Implications and recommendations for designing OCW module based on the results were suggested.

최근 고등교육의 기회와 혜택이 일반인에게 평등하게 열려야 한다는 세계적 취지로 대학 및 비영리 기관에서는 다양한 강의 컨텐츠를 대중에게 제공하고 있다. 이러한 움직임의 일환으로 오픈코스웨어(OpenCourseWare, OCW)가 일반인들에게 제공되어 그 이용 또한 활발한 경향을 띤다. 이에 본 연구는 오픈코스웨어(OCW) 정보자원이 어떻게 이용 및 활용되는가를 알아보고자 국내 A대학 학생들을 대상으로 일대일 면대면 인터뷰를 수행하여 이들에게서 공통적으로 나타나는 이용 행태 유형을 이용측면, 컨텐츠 활용측면, 이용시 만족측면으로 나누어 분석하였다. 이를 통해 향후 오픈코스웨어(OCW) 연구의 기초적인 정보를 제시해 보고자 한다.

The purpose of the study is to identify the usability of OpenCouresWare(OCW) from the perspective of students with visual and hearing impairments. Twelve college students with disabilities(8 visual and 4 hearing impairment) implemented usability testing. Two modules in both edX and KOCW were selected for testing. Students with disabilities implemented usability testing and then each individual case was analyzed through quantitative and qualitative methods. As results, the degree of general usability in both edX and KOCW indicated an average level and the degree of accessibility in edX module was evaluated higher than KOCW. Specifically, the module of edX was rated highly by students with hearing impairments and the usability level of KOCW module was highly appreciated by blind students.

The effect of eight varieties of grain and forage type whole crop rice (Oryza sativa L Japonica) each harvested at four stages of maturity were investigated for morphology and yield, proportion of botanical fractions, fermentatability and chemical composition in an $8{\times}4$ factorial experiment. All crops were sown in 1997 at Saitama Prefecture, Japan under identical condition and harvested on 10, 22, 34 and 45 days after flowering in 1998. Total DM yield of forage type varieties was similar to that of the highest yield of grain type varieties. However, while yield of forage type varieties was attributed to higher proportion of straw than head, the reverse was in the case of grain type varieties. Yield in line with the proportion of head increased (p<0.001), but in contrast proportion of straw decreased (p<0.001) with the increase in maturity. Silage fermentability of grain type varieties was better than forage type varieties. Fermentability improved with the increase (p<0.001) in maturity suggesting that the moisture content should be reduced to improve fermentation quality. Forage type varieties contained higher (p<0.001) ash, crude fat (EE), organic cell wall (OCW) and acid detergent fiber (ADF), but contained lower crude protein (CP), organic cell content (OCC), CP in OCC and nitrogen-free cell wall extract (NCWFE) than the grain type varieties. The ash, CP, EE, Oa (60% digestible OCW), Ob (40% digestible OCW), OCW, ADF and acid detergent lignin (ADL) decreased (p<0.001), but OCC and NCWFE increased (p<0.001) with the increase in maturity. It is concluded that stage of maturity not only increases yield and proportion of head, but also improved the fermentation quality and increases quality chemical composition (except CP) of whole crop rice. Forage type varieties may be as good as grain type varieties in terms of yield, but fermentation quality and chemical composition may not be as good as that of grain type varieties.

This study has extracted the basic component of the Library Course Pages through case studies of the Library Course Pages Service, and examined the staus quo of the Open Course Ware(OCW) for the sharing of the course materials. The study has also designed and established a ontology-based retrieval system model that is capable of semantic-based retrieval of the course materials in colleges. A comparison between and analysis of the past keyword search results was conducted to evaluate the model. Through evaluation, the study concluded that the ontology-based system was more effective than the keyword search method in both retrieval result and material sharing between the institutions.

MOOCs become an innovative counterproposal of higher education while leading qualitative and quantitative expansion of open courses. KOCW which has adapted for providing open courses in Korea is expected to be evolved along with the development of MOOCs. However, there is a chance to have a conflict or resistance if MOOCs will be transferred without considering domestic situations or opening of universities' classes won't be able to evolve in OCW environment anymore. In this case, it will be hard to take advantages of MOOCs' that provide opportunities for embodying popularization and individualization of education. Thus, it is important to develop strategies for employing recent trends of MOOCs in Korean environment for the sustainable development of higher education. In this paper, design elements required for Korean MOOCs has been studied through SWOT analysis.

E-learning has the potentials to provide educational publicity and equality, and has been deployed rapidly in many areas of our society. Growth of e-learning market is also rapid and sustained. However, for e-learning to be a good solution, enough contents should be provided, for which sharing limited contents in the early deployment stage should be necessary. In this paper, we survey some activities about contents sharing. On the other hand, there have been many complaint from e-learning about its effectiveness. Therefore, in this paper, based on the poll results on concentration and satisfaction of e-learning, we also study practical ways to improve studying efficiency of e-learners.

공개자원운동의 일환으로 등장한 OER, OCW 컨텐츠를 정보자원으로서 관리해야 할 필요성이 커지고 있다. 이에 본 연구는 국내 대학도서관 OER 현황분석을 하고자 한다. 이를 위해 성균관대학교, 숙명여자대학교, 부산대학교를 분석대상으로 선정하였으며, 컨텐츠 및 컨텐츠 품질, 홍보, 플랫폼 세 항목을 기준으로 분석하였다. 그 결과 첫째, OER을 정보자원으로서 체계적으로 수집 관리해야 할 대상으로 보고 있지 않았다. 둘째, OER 서비스 활성화를 위해 적극적으로 홍보가 이루어지지 않고 있었다. 셋째, 이용자들이 참여할 수 있는 OER 플랫폼은 구축되어 있으나 이용자들이 쉽게 접근할 수 있는 수준이라 보기 어려웠다. 이에 대한 해결 방안을 모색하여 대학도서관이 교내정보자원의 통합관리기관으로서 역할제고 방안에 대해 고찰하는 것에 의의가 있다.
