This paper aims to provide information to generate a statistical load model of an educational server by analyzing workload of an e-Learning sewer at Dankook University. The result of the analysis shows file size distribution, access frequency and transmission volume for each file type, access interval, changes in preference and clients access rate by networks. In particular, it had different results from previous studies about video file's size distribution and file distribution based on access frequency. This is because the characteristics of e-learning are influenced by using authoring tools for making into video file and by freeing the number of students who register for a course. The result in this paper can be used as a basic data for studies designed to improve e-learning system architecture and server performance.

E-learning has improved the educational effect by making it possible to learn anytime and anywhere by escaping the traditional infusion education. As the use of e-learning system increases with the increasing popularity of e-learning, it has become important to measure e-learning satisfaction. In this study, we used the mixed research method to identify satisfaction factors of e-learning. The mixed research method is to perform both qualitative research and quantitative research at the same time. As a quantitative research, we collected reviews in Udemy.com by text mining. Then we classified high and low rated lectures and applied topic modeling technique to derive factors from reviews. Also, this study conducted an in-depth 1:1 interview on e-learning learners as a qualitative research. By combining these results, we were able to derive factors of e-learning satisfaction and dissatisfaction. Based on these factors, we suggested ways to improve e-learning satisfaction. In contrast to the fact that survey-based research was mainly conducted in the past, this study collects actual data by text mining. The academic significance of this study is that the results of the topic modeling are combined with the factor based on the information system success model.

In this paper, we propose u-learning hub site systems which are designed and implemented based on learning activities oriented components. The proposed systems are composed of component which can process the functionalities for coming into action of learning activities through various devices. Specially, each component is broken into class units by which learning activities of users can be performed on various devices. When users try to connect u-learning system in hub site, the system explores devices of users and connection program and then selects components that are fit to the activities and combines them in realtime. Through the methodology of u-learning hub site, the system proposed in this paper provides u-learning environment so that users can use the learning activity services taking no influence on time, place, devices and programs under the consistent system. That is different to traditional e-learning system which cannot support various devices of users directly.

최근 디지털 지식기반 사회에 대응하는 교육의 형태로 e-Learning이 교육적 대안으로 급부상하면서, 시스템의 상호 운영성 및 컨텐츠 명세, 활용을 지원하기 위한 표준화에 따른 연구가 국내외에서 급속도로 확산되고 있다. 특히, 국제표준기관에서 제시한 e-Learning 개발 환경을 위한 Learning Technology Standard Architecture(LTSA)와 Sharable Content Object Reference Model(SCORM)을 제정하여 컨텐츠의 사용과 상호 호환을 가능하게 함으로써 e-Learning의 효율성을 증대시키고 산업 시장의 확장을 이룰 수 있다. 또한, 현재 많은 교육관련 업체에서는 SCORM 체계를 기반으로 한 학습 컨텐츠들을 개발하여 제공하고 있다. 따라서, 본 논문에서는 국제 표준 기술인 SCORM을 기반으로 개발된 학습 컨텐츠를 체계적으로 지원하기 위해 컨텐츠 관리 시스템 개발에 대한 기술을 정의하고, 다양한 관점의 컨텐츠 메타 데이터를 식별, 분류함으로써 컨텐츠의 생성과 저장, 검색 나아가 형상관리를 위한 기본 정보로 이용 가능하다. 또한 이들 메타 데이터를 기반으로 한 학습 컨텐츠 관리 시스템의 프로토타이핑을 제시함으로써 재사용성과 유지보수성 향상을 통해 컨텐츠 개발의 용이성과 품질 및 생산성을 높일 수 있다.

The purpose of the research is to investigate the perception of corporate and e-Learning institute on ubiquitous society and learning environment in the context of human resource development. In addition, the study aims to analyze their recognition of u-Learning's components into the level of significance and actualization. The total of 118 institutes were participated in the research survey among the 144 e-learning certified institutes from the Ministry of Labor. The research includes the results of survey and implications on the area of human resource development.

In business training, the biggest change through training plan, choosing trainees and conducting the training has been on education environment by information system. These changes are to attain effective learning based on the customer not the supplier. However there are still passive operation on the companies' strategic training course. Accordingly, the purpose of this study is to offer alternatives for the difficulties on educational training operation and to find the way for effective operation.

Video-demand learning through E-learning continuously increases on these days. However, not all video-demand learning systems can be utilized properly. When students study by education videos not matched to level of their own, it is possible for them to lose interest in learning. It causes to reduce the learning efficiency. In order to solve the problem, we need to develop a recommendation system which recommends customized education videos according the study levels of students. In this paper, we estimate the study level based on the history of students' watching behaviors such as average watching time, skipping and rewinding of videos. In the experimental section, we demonstrate our recommendation system using real students' video watching history to show that our system is feasible in a practical environment.

For the purpose of an effective instruction-learning process by systematic management of knowledge between instructor and learner in e-Learning, we have developed the authoring system in which the instructor is able to author easily on various lecture frames according to the instructional design theory. The authored contents with the relations among the learning objects based on SCORM standard would help learner to conceptualize the contents. A knowledge map is constructed on the relations among the learning objects using RDF of the semantic web. We introduce the ontology in which the instructor can make a dictionary of terminology by registering the words of the teaching area. The learning activity and comprehension of students can be assessed using each student's learning map along the interaction points which are introduced to present the individual learning by considering each student's capacity of understanding and achievement.

이 연구의 목적은 2003년부터 농촌진흥청에서 이루어져 왔던 이러닝시스템에 대한 실태와 참여농가의 만족도를 파악하고 향후 이러닝시스템의 발전방향을 모색하는 데 있다. 농촌진흥청은 2003년부터 웹과 비디오화상시스템에 기반을 둔 이러닝시스템(e-learning system)을 이용하여 농가에 대한 지도와 교육사업을 전개하여 왔다. 2003년에는 이러닝을 통한 교육과정에 251명의 농민이 등록하였으며, 이 중 최종적으로 126명이 오이, 고추, 토마토에 대한 생산과 경영관리 교육과정을 수료하였다. 2004년에는 503명의 농민이 이러닝 교육과정에 등록하였으며, 이중 313명의 농가가 버섯, 딸기, 수박에 대한 생산과 경영관리 교육과정을 수료하였다. 이러닝 교육과정에 참여하는 농민의 76%가 이러닝시스템을 통한 교육에 만족하는 것으로 나타났다. 이러닝을 위한 시스템 형태에 따른 선호도는 비디오화상시스템만을 이용한 경우는 23%. 웹만을 이용한 경우는 13%, 이 두 시스템을 통합하여 운영한 경우에는 59%로서 통합시스템운영이 더 효과적인 것으로 나타났다. 현재 진흥정이 구축한 통합시스템은 동시에 1000명 이상의 농민을 대상으로 교육을 실시할 수 있다. 지도사업의 예산과 인원이 과거에 비해 줄어들고 있는 상황에서 이러닝시스템은 향후 농민들을 대상으로 한 지도와 교육에 효과적인 대안이 될 수 있다.
