The tendency of multimedia services and market of specialized information is currently much debated issur in our country. Nevertheless, the systematic investigation of demand for multimedea database is nowadays nowhere to be found. The purpose of this study is to gain a general overview of market and demand of service relating to multimedea database. At first, various definitions of multimedia, multimedia content, and multimedia database are analysed and evaluated from the point of technical and practical views. For the study on the demand for multimedia database of specialized information, database catalogue of DPCK 1997 and multimedia database on internet are analysed. After that the results of expert survey to estimate an accurate tendency of multimedia services in Korea are analysed.

Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.

The purpose of this study is to present the importance of systematic database education in elementary and secondary schools in Korea. The authors compared the curriculum for database education in elementary and secondary schools of Gyeongsangbuk-do province in Korea with that of Arcola schools in the state of Illinois, US. The database industries of both countries were also compared to suggest the significance of database education in Korea. We have shown that it is urgent to include database education in IT curriculum for elementary and secondary schools in Korea considering importance of database itself as well as the magnitude and growth rate of database industries in 21st century. Contrary to our research results, however, it is shown the IT curriculums of elementary and secondary schools in Korea is hardly adequate to provide systematic database education required in information society. Based on these results, we conclude that IT curriculums should be revised to accommodate systematic database education for elementary and secondary schools in Korea.

To determine efficient methods of database teaching, this paper applied the situated learning theory to the teaching and learning method and analyzed the effects. Previous related studies were also examined, with the essential contents in database analyzed based on Bloom's taxonomy of educational objectives. Moreover, this paper presented a strategy wherein the contents of database learning are classified into two categories: basic knowledge and technical and extended knowledge. Experimental and control groups were selected based on related studies, and the effects of database teaching and learning method, determined by technique and attitude area as well as knowledge area. After preparing and applying to the teaching and learning method the actual educational curriculum, the following results were drawn: (1) the experimental group showed better performance in terms of understanding the concept of database, operating database, and constructing a database table when the situated learning theory was applied to the teaching method, and; (2) the experimental group was also more receptive compared to the control group, which opted to take technique-oriented database courses. Therefore, various teaching and learning methods aside from the situated learning theory should be applied and analyzed in database and computer science fields for maximum effects.

객체지향 데이터베이스 보안모델은 객체지향 패러다임의 각 속성에 대한 보안정책을 정의한다. 객체지향 데이터베이스의 보안 목적은 데이터베이스에 대한 권한이 없는 사용자의 접근을 제어함으로써 정보의 고의적인 파괴나 변경을 방지하고, 우발적인 사고로부터 데이터를 보호하는 것이다. 일반적인 데이터베이스 보안모델은 임의접근제어(DAC)나 강제접근제어(MAC)를 이용하여 보안문제를 해결하였지만, 이 논물에서는 역할기반 접근제어를 객체지향 데이터베이스에 적용해서 보안문제를 해결한다. 따라서, 기존의 객체지향 데이터베이스의 보안속성과 보안정책에 기반한 주체, 객체, 접근모드들을 정의하였고, 개념적인 클래스를 설계해서 객체지향 데이터베이스의 보안모델을 제시하였다.
