As the development of information technology, the biggest change in educational paradigm is apparent in the shift that the emphasis of education is layed on from teachers to learners. E-learning education service through the internet is less restricted in the respect of time and places in comparison with off-line education. Therefore e-Learning is spreaded rapidly and the educational effectiveness of that is needed to be investigated. In this study theoretical research was performed firstly and framework of the study was constructed. After establishment of hypotheses the survey data were collected by the learners of e-Learning and the hypotheses were verified by the SPSS version 12.0. The results are as follows : First, the quality of e-Learning service influences significantly to the technology acceptance of users. Secondly, perceived usability and perceived easiness of technology acceptance model influences significantly to the intention of reuse of users of e-Learning services. Lastly, the playfulness of the Flow theory influences significantly to the intention of reuse of users of e-Learning services. Although there are some limitations in the respect of the numbers of variables, parameters, or samples, this study will contribute for enhancing the effectiveness of education in e-Learning service by providing the acceptance factors of e-learners.

현재 적용되고 있는 7차교육과정은 학생들의 평가에 있어 종전의 1회성 평가가 아닌 단계별 수시평가의 하나인 수행평가의 중요성을 강조하고 있다. 이러한 결과로 일선 학교에서는 종이로 된 수행평가 결과물을 파일에 보관하는 전통적인 아날로그식 포트폴리오의 방법을 도입하고 있으나 많은 단점이 지적되고 있고, 이러한 전통적 포트폴리오의 단점을 보완할 수 있는 방법으로 e-portfolio의 방법이 제시되고 있다. 본 연구에서는 웹기반 수행평가를 시행하기 위한 e-portfolio 시스템을 설계, 구현하여 이를 초등학생의 교과 수행평가에 직접 적용해 봄으로써 웹기반의 e-portfolio가 주는 교육적 효과를 알아보는데 연구의 목적이 있다.

This study presents an analysis of the current situation (management, approach, adjustment, transportation, and others) of teaching portfolio by examining the teaching portfolio managers (staffs, researchers, teaching assistants, etc.) of 6 universities in the southeast of Korea. The rationale for the study focus is that the existing teaching portfolio either suffers a problem in the transportation, approach, adjustment and/or management or is likely to raise a problem in the future. In order to solve this problem, this study builds a web-based e-teaching portfolio. According to the analysis results, the engineering education system was established in all 6 universities (Ed- note that '6 universities' has already been specified as the study sample). The teaching portfolio was partially digitalized in this system, despite some problems of converting analog data into digital data, which induced difficulties in constructing the overall e-teaching portfolio. Therefore, this study focused on constructing an e-teaching portfolio without developing any additional system by using the existing system positively, and also on determining the appropriate components among the existing teaching portfolio components. Accordingly, in order to convert the analog data into the digital data required for this study, we used a digital camera as the conversion device and converted the teaching portfolio components into those appropriate for the e-teaching portfolio. Finally, we constructed an existing system appropriate for the e-teaching portfolio by using these devices and components.

The purpose of this study was to establish a model for constructing longitudinal data for medical school, and to structure cohort and longitudinal data using data from Yonsei University College of Medicine (YUCM) according to the established input-environment-output (I-E-O) model. The study was conducted according to the following procedure. First, the data that YUCM has collected was reviewed through data analysis and interviews with the person in charge of each questionnaire. Second, the opinions of experts on the validity of the I-E-O model were collected through the first expert consultation, and as a result, a model was established for each stage of medical education based on the I-E-O model. Finally, in order to further materialize and refine the previously established model for each stage of medical education, secondary expert consultation was conducted. As a result, the survey areas and time period for collecting longitudinal data were organized according to the model for each stage of medical education, and an example of the YUCM cohort constructed according to the established model for each stage of medical education was presented. The results derived from this study constitute a basic step toward building data from universities in longitudinal form, and if longitudinal data are actually constructed through this method, they could be used as an important basis for determining major policies or reorganizing the curricula of universities. These research results have implications in terms of the management and utilization of existing survey data, the composition of cohorts, and longitudinal studies for many medical schools that are conducting surveys in various areas targeting students, such as lecture evaluation and satisfaction surveys.

This study was carried out to reduce children's sugar, natrium and fat intakes and establish their healthy lifestyle. To achieve these goals, we developed an educational web site and an e-learning system. The targets of this web site are children, parents and educators. This site has various information about sugar, natrium and fat, and has special menus for each target: such as the 'Let's study' for children, 'Guides for child's eating' for parents, and 'Educational softwares, Lesson plans/materials, and Textbooks/Teaching guides' for educators. We developed three nutrient characters and applied them to the web site. We provided information in the form of texts, images, flash and sounds. This site has special boards in 'Nutrition cafe' menu to interchange information or their successful stories between the connecters. We developed an e-learning system with two courses. One is for junior elementary students and the other is for senior students. Children can study each nutrient step by step in a course according to their academic ability and concern. Also, they can evaluate their academic achievement in this system, which was uploaded into 'Let's study' in children menu in the web site. Conclusively this web site and e-learning system could contribute to reducing children's sugar, natrium and fat intakes by helping children study them systematically and effectively by on-line system. We expect this e-learning system would be a new nutrition education system to make nutrition education more active.
