This paper explores ways to develop efficient methods to construct the web-based interior design database based on hypermedia technology. First the role of hypermedia in design was investigated. We propose the structure of knowledge representation for interior design works. Also, we discuss how a design case can be retrieved from the design database. This paper also identified further research issues such as design case retrieval from numerous design cases and components of the virtual design studio.

문화예술 정보는 텍스트, 이미지, 동화상등의 다양한 멀티미디어 데이타로 구성되어 있다. 이를 효과적으로 검색하기 위해서 노드와 링크로 구성된 하이퍼미디어를 사용하였다. 지금까지는 우선적으로 문화예술 정보중 연극 정보와 문화재 정보에 대하여 프로토타입을 구축하였으며, 계속하여 문화예술 전분야로 확대해 나갈 것이다. 연극정보를 검색하기 위해서는 데이타베이스 검색과 키워드 검색을 이용할 수 있으며, 최종적인 검색 결과는 하이퍼미디어 뷰어 (Hypermedia Viewer)인 Mosaic를 이용하였다.

To support cooperative work in various scenes by computer systems, functions of sharing personalization, observation and control are needed. Especially, in advanced cooperative work, people have various position so that sometimes one person needs to restrict behavior of another. In this paper, we describe representation of access restriction of hypermedia system, which is framework of CSCW(Computer-Supported Cooperative Works) system we developed and propose a way to go on working cooperatively with people, restricting others.

The purpose of this paper is to examine some effects of four menu types: icon menu, icontext menu, pulldown menu, and bar selection menu. Each have been mainly used with hypermedia instruction, learners' metacognition on their errors, menu search time, and scholastic achievements. A further purpose of this paper is suggest some strategies for enabling each learner to select menus more efficiently in order to enhance the learner's own learning effectiveness in hypermedia instruction. There were 100 college students selected as subjects for This study. They had never had experience in Hanoi hypermedia instruction. They were required to use four menu types at random in this experiement. The results of this study are as follows. The menu types had a significant effect on the low metacognition regulation group. Icontext menu types, especially, had a significant effect on achievements. In constrast to this, the menu types did not have any significant effect on the high metacognition regulation group.

With the rapid growth of the Web technologies, the Web has changed teaching and learning as well as our life in various ways. Web-based instruction (WBI) supports self-directed and creative learning at anytime anywhere. However, learners may experience the problems of disorientation and cognitive overload when the hyperspace that consists of learning materials is complex. In this paper, we present a Web-based adaptive hypermedia system based on cognitive load theory which can reduce cognitive loads that novices may experience when they learn programming

This study investigated the relationships between hypermedia users information processing styles and navigational patterns. Three aspects of navigational patterns were investigated: (a) navigational breadth patterns which reveal how comprehensively users access, (b) navigational path patterns which display what sequences users follow. and (c) navigational method patterns which show what methods u users employ when using the system. Information processing styles were measured by the Human Information Processing Styles(HIPS) Survey. The subjects were 102 undergraduate students enrolled in management courses at a university. Participation was voluntary 34 students were selected for each of left, right, and integrated information processor group. The subjects interacted with A.g.i.l.e. TrainerTM program to complete two types of searching tasks 'open-ended and closed-ended tasks' Findings indicated that the information processing style seems to play an important role in how an individual interacts with the hypermedia systems.

The problems of developing web based adaptive hypermedia for education using XML are discussed in this paper. We define two different markup languages using XML. The one structures the domain model and the another describes the user model. These language can be easily extended and authored, with the result of obtaining a simple methodology for data structuring in the field of web based educational adaptive hypermedia. Also, We have suggested three learning rules that automatically restructures hypertext networks according to their user browsing behavior. The user profile is contained in a user model, while the knowledge about the domain can be represented in the form of a concept based domain model. Accordingly.

Conventional hypermedia systems provide a simple data model based on nodes and link, and give us the limited capability in information retrieval such as browsing and navigating following the links. In this paper, we design and implement a hypermedia system (AHEAD) with enhanced data modeling and querying capability, which are strongly supported in object-oriented database technology. The AHEAD makes it possible to model the accurate data semantics and relationships in application domain, to represent useful information related to nodes and links, and to define the structure and manipulation operations of multimedia data. It also support the various querying capabilities by using modeling information.

Information management area faced new challenge arised from the developments of the computer and the information network, and the advent of information super highway. With deep perception of importance of the information, developments of information technologies, and change of the users' environment, we came to envision the digital library. This paper intends to describe the concept and function of the digital library, and to examine some of information technologies such as CD-ROM, OCR technology and image scanning, hypertext, hypermedia and multimedia. And it also considers the strategies for electronic information services and the applicability of the current information technology for digitalization by case studies of the existing database systems.
