The human computer interaction has gone through diverse changes along with the technical progress of computers. With the spread of the world wide web, attempts of various forms and methods of interactions reflecting the characteristics of the web are being made. Among the diverse concepts of interaction, Conversational Agent uses a character as the visual perceptional object and through the interaction based on conversation it suggests a natural, human, intuitive interaction. In this study, Conversational Agent was suggested and applied on a cyber lecture website and the appropriateness was verified. The fundamental structure and method needed in constructing a conversation was examined through the study on conversation. After that the characteristics of the conversation used on the web was identified and hereby and the coherence and conversation structure was deducted. After the characteristics of the conversational agent were observed, it was applied to the previously deducted web sites logical connection and conversation structure. Lastly, the conversational agent suitable for the web site was proposed and realized.

XML은 모든 분야의 데이터를 저장하고 다른 형태의 데이터로 변화될 수 있는 강한 힘을 지니고 있다. 웹에서의 가상 교육에 대한 데이터도 XML로 저장한다면 한번 저장된 데이터는 어떤 사이트에서든 조금의 수정없이 바로 사용할 수 있다. 물론 이 데이터 구조가 미리 정의되어 모든 사이트에서 이 구조대로 XML 데이터를 만들어야 가능하다. 현재 사이버 교육 사이트들의 강좌 데이터는 데이터베이스에, 데이터베이스에서 데이터를 가져오는 것은 ASP, 가져온 데이터를 사용자에게 서비스하는 최종 산출물은 HTML로 구성되어 있어 이 데이터는 더 이상 가공을 할 수 없게 된다. 즉 각각의 사이버 교육 사이트들의 데이터는 서로 공유될 수 없다. 본 논문은 현재 사이버스쿨의 한계를 벗어날 수 있도록 새로운 표준으로 제안되어진 XML을 이용하여 사이버 강좌 관리시스템을 위한 통일된 XML 데이터 구조를 정의하고 웹에서 어떻게 사용해야 하는지 모델을 제시하였다.

컴퓨터 기술 발전에 발맞추어 교육 분야에서 전통적인 교육 방식을 대체하는 사이버 교육이 활성화되고 있다 사이버 교육은 멀티미디어 등 컴퓨터 기술력을 바탕으로 off-line 교육이 가지는 교육의 질을 구현하고는 있지만, 실험, 실습이 필요한 교과목이나 학습자와 교수자 간의 정서적 교류가 요구되는 과목 등을 위하여 연구의 필요성이 제기되고 있다. 본 논문은 학생들이 직접 실험, 실습을 하고 있다는 현장감을 줄 수 있는 가상현실 기법을 사용하여 실험, 실습이 필요한 과목을 On-Line화 하는 방법을 제시하였다.

A purpose of the system proposed in this paper is to help learners pursue proactive and self-oriented education by allowing learners to proactively configure their own content, that is, learners no longer have to be restricted by prescribed sequence of lectures. In general, most LMSs cannot meet every individual's educational needs because they structure their programs by letting learners simply choose from a list of available lectures at prescribed level or difficulty. However the Self-Leading LMS eliminates such boundaries by allowing learners to choose contents and difficulty within the limit set by their own educational competence.

The purpose of this study was to investigate the influence of distance education experience using users' avatars in virtual reality space on their teaching efficacy belief. There were 9 participants who were enrolled in a course in doctoral program of education department in J University for the study. The first class of six sessions was face to face class on how to use Second Life and the 14 classes of 3 sessions were done in a classroom of Second Life. According to the analysis of reflection notes, interviews, researcher's observations of 5 participants, their experiences of presentation and taking classes in distance education using their own avatars in Second Life had positive influence on participants' teaching efficacy belief in their future working for distance education using avatars of Second Life. The implication of this study is to show some conditions for successful distance education as well as to see the potential of distance education in 3D virtual reality space using avatars. This study will contribute to promote the future study in distance education field.

The speedy development of the world-wide web is rapidly growing the internet-based tools for the remote instruction. In interchanging and expressing the information of one another on the web, it is produced through the form of HTML(Hyoertext Text Markup Language). However, the structural disadvantage of the HTML is becoming to require a powerful XML(eXtensible Markup Language) which can store all the sphere of data, and transform them into another form. Nevertheless, because the powerful XML(eXtensible Markup Language). However necessary that XML standard should be applied appropriately. Because existing lecture data of cyber education sites cannot be shared, the users should passively use only the functions offered by cyber school. To solve the problem of this limit, in this study, the standardized data structure for XML is defined, and system model for processing between the server and the client is provided. By storing the lecture data of cyber education sites as XML on the web, stored data came to be reused without changing on any site. In the view of Users, they could used the Internet service with equipment that they want at any place and any time. To control any kinds of CK\LMS(Cyber Lecture Management System) for Administrator and Users, we offered a variety of Multimedia applications and an easy interface and built a new style of CLMS. Therefore, by strong and extracting the data related with the virtual education of the secondary school through the form of XML, for the effective interchange and sharing of the information, maximum utilization of the information can be achieved.

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.

The World-Wide Web provides new opportunities for cyber education over the internet. The web, when combined with other network tools, can be used to provide useful educational information to learners. Thus, the objective of this paper is to develop Java applets for understanding the principles of electronic circuits on the internet. Some sample Java applets are illustrated as an example. The results of this paper can be widely used to improve the efficiency of cyberlectures in the cyber university.

Recently, according to the appearance of various virtual websites using multimedia technologies for engineering education, the internet applications in engineering education have drawn much interests. But unidirectional communication, simple text/image-based webpages and tedious learning process without motivation etc. have made the lowering of educational efficiency in cyberspace. Thus, to cope with these difficulties this paper presents a web-based educational Java applets for understanding the principles or conceptions of digital logic systems. The proposed Java applets provides the improved learning methods which can enhance the interests of learners. The results of this paper can be widely used to improve the efficiency of cyberlectures in the cyber university. Several sample Java applets are illustrated to show the validity of the proposed learning method.

This study proposes a method to effectively teaching technic for pattern development and virtual garment manufacturing by adopting the K-MOOC platform for the Apparel Pattern CAD curriculum. According to K-MOOC guidelines, Apparel Pattern CAD curriculum were developed and presented through the K-MOOC platform. A questionnaire survey was utilized to evaluate K-MOOC platform features in terms of learner satisfaction when adopting the 5-point Likert scale. Questionnaire survey participants included 52 college students. The result of the survey found that most of the attributes of the K-MOOC platform were highly rated in terms of interaction and learning effectiveness. The user interface of the K-MOOC platform were shown to be satisfactory in terms of usability. Participants gave a positive assessment of the benefits of online lectures when comparing online and offline lectures. In particular, the preference for online lectures in computer-related courses such as CAD was higher than the offline. It was concluded that the Apparel Pattern CAD curriculum based on the K-MOOC platform was effective and satisfactory for learners in various aspects.
