Implementation of Microbial Active Database Using Web / 대한의료정보학회지

OBJECTIVE: The contents of microbial information are complicated because of being hierarchical, duplicated as well as their changes are continuous and various. Much of time and cost are required for maintaining, expanding the information after representing them into a relational database. The relational database is not adequate to make the information sharable via Internet. In addition, user's meta-knowledge is insufficient to use the information via Internet and users may not be able to cope with the continuous changes of microbial information through the static web interface. Therefor, this study is conducted to develop an active microbial web database for resolving those problems. METHODS: To solve these problems, object-oriented database, which was able to represent the complicated contents and knowledge, was used, and intelligent agents were implemented to cope with the continuous evolution of microbial information. Also, they were incorporated into user interface to assist users in an interactive environment, who want to use information via Internet. RESULTS: The implemented system have shown advantages of solving difficulties arising from hierarchical and duplicated microbial data. It showed the possibility to share and manage the complex microbial data via Internet. It helped the system to be implemented as the active database, information stored in the object-oriented database. CONCLUSION: This study indicates that a similar approach may lead to develop an expert system based on the web and active database, which is able to be evolved, and to develop intelligent interface, using the agent.

Development of Oral Pathology Learning Support System based on MMDB / 대한의료정보학회지

Collecting, managing and processing course material requires of much costs and efforts while they include a variety of data types particularly in the health field. Some engineering work on the material may help reduce the workload and costs to some extent. With such benefits having in mind, this paper tries to develop multimedial database for the course material of Oral Pathology in dental schools. It provides structured analysis of data for the course material, in which a unit of disease is a central class with relation to many other classes. It also achieved data independence from server applications by using the method concept of object-oriented database(OODB), which will increase reusability of the course data. Using another important concept of OODB, the system devised many functional utilities on an Internet web server including lecture notes, case studies, disease search, and question and answer, and shows how they are operated. But the effectiveness for the part of student users may remain to be evaluated.
