Science and Technology University(STU) will be established by twenty-two government institutes next year. STU has latent problems with geographical limitations caused by organizing the faculties and facilities of the government research institutes, which are located all over the country. This study tries to examine the Educational Administration(Opreation) Model of STU and analyse expected problems and further, proposes the introduction of cyber education system which will maximize efficiency of educational operation of the system and enhance learning. It also discusses the practical problems in the implementation of cyber education system.

Many aspects of the way we work and live in the twenty-first century will be determined by the vast web of Internet. Virtual environments open the door to new identity experiences. Having the possibility to enter in a new community, where any personal information is directly shown to others, is a possibility to experiencing different self and thus to show and build new identities. This paper aims to identify how to relate the perception of cyber identity, loyalty and purchase intention. First, we classified cyber identity into two types, personal and social, and analyzed perception of each identity type. Then we conducted a survey using pre-designed questionnaire and found out factors consisting personal and social identity. Finally we analyzed the effects of these factors on loyalty and purchase intention using Structural Equation Model.

본 논문에서는 월드와이드웹에 기반한 학습자 중심의 통합 가상교육시스템 CyberClass를 설계하고 구현한 방법을 소개한다. 기존의 가상교육시스템은 학습자 중심의 상호작용 유형을 분석하여 이에 따른 적당한 상호작용 모델을 제시하지 않고 기능면에서의 사용도구 및 방법만을 제시함으로써 각 기능들이 자연스럽게 통합되지 못하였다. 따라서 전통적인 교육 방식인 강의실 수업에 참여한 학습자들이 가지는 현장감이나 친밀감에서 오는 커다란 교육적 이득을 제공하지 못하였다. 본 논문에서 개발한 가상교육시스템 CyberClass는 학습자 중심의 상호작용유형을 분석하고 이를 기반으로 상호작용모델을 제시한다. 그리고 제시된 모델에 기반하여 학습자와 교수, 학습자와 학습자 나아가 학습자와 가상교육시스템간의 상호작용에 기반한 시스템을 설계하였다. 따라서 학습자의 상호작용 모델에 기반함으로써 학습 참여도나 학습 능률의 향상을 기대할 수 있다. CyberClass는 학습자 중심의 상호작용을 위해 비동기공유 기공과 동기고유 기능을 모두 지원한다. 이들의 공유 기능들은 유기적으로 결합하고 직관적인 학습자 인터페이스를 제공함으로써 학습자에게 기능의 다양성에 따른 학습의 부담을 줄이고 자연스런 학습과정이 유도되도록 하였다.

Providing female students with competitive advantages in their social activity became one of the important issues of the college education in Korea. Thereupon, for the purpose of more effective and systematic support for the female students, many universities have adopted the cyber mentoring system. However, customers' requirements for such cyber mentoring systems are not reflected at the initial stage, resulting in some inefficient performances. In this study, we propose a desirable cyber mentoring system reflecting female students' requirements by using QFD and conjoint analysis. We expect that the proposed system will help to cultivate high quality female resources in a more effective way.

This paper suggested a cyber collaboration platform based on web for food safety service. We implemented the cyber collaboration platform for food safety service so that the users participated in collaborative work may refer shared media objects as the same view to others. In this paper, we discussed a model for increasing reliability of food safety data through N screen server and client model. This paper explained a performance analysis of a system with function comparison running on multimedia collaboration work based on web and N screen techniques.

비트코인은 각국의 중앙은행이 화폐 발행을 독점하고 자의적인 통화 정책을 펴는 것에 대한 반발로 만들어진 암호화 된 디지털 화폐이며, 2008년 10월에 처음 등장하였다. 새로운 전자화폐로 성장한 비트코인은 현재 여러 나라에서 서비스되고 있으나 보안상의 취약점들이 발견되면서 이를 보완해야 할 필요성이 대두되고 있다. 본 논문에서는 비트코인의 특징과 서비스현황을 알아보고 비트코인의 취약점 중 지나친 익명성, 이기적인 채굴 그리고 51% Attack의 취약점들을 대상으로 분석하고, 대응 방안에 대한 한계를 제시한다.

Internet-based cyber shopping mall has recently become the focus of interest among many researchers in the field of information systems. It is because of the widespread use of Internee and of the novelty of the cyber mall as a new business practice. This research attempted to provide grounded guidelines for this business style based on a qualitative indepth analysis of the experience of two cyber malls. The two research sites had different company backgrounds, one as a retailer and ther other as an IT service provider. Implications of the analysis were drawn in terms of the business strategy and operating tactics.

To make cyber universities competitive, the level of the learning effect for students should be improved. The objective of this study is to analyse the factors influencing the learning effect of cyber universities. For this purpose, questionnaire survey has been used. For the statistical analysis, multivariate linear regression were utilized using the SAS program. According to the results in this study, the variables that influence toward the learning effect are the experience of computer, the systematic and comprehensive lecture note, and the quickly responses to questions. These variables can be utilized in improving the educational service quality of cyber universities.

Academic libraries need to support effectively cyber education which should be managed successfully. When the information materials and library services for distance learners are supported efficiently, they can maximize learning effects. This study explored the role and function of academic libraries that seek to support cyber education successfully through previous foreign studies and presented the elements of the librarian, library service, digital library, library administration and policy that academic libraries must consider to support cyber education successfully.
