The purpose of this study was to design and implementation of database for school health activity. This database system was designed stand-alone application for college school health center without a hospital affiliation and the database system was made of relational database management system, Microsoft access 2000 to be made GUI (Graphic user interface) type design and made up 7 tables: patients. symptoms. departments, income and outgo. medical cures. and medicine. The construction of this database system was patient management. code management. medicine management. and statistics management. The results of the database system were as follows; 1) This database system could be used for college school health center. 2) This database system could be made correct statistic data. 3) This database system could be managed income and outgo. 4) This database system could be changed for the better activity of community health service. 5) This database system could be simply attired administrative system. This database system will be used for students and employees to protect and promote health to measure for health level and quality of health service. In conclusion. this database system can be applied for unit health center to manage the college school health activity and advanced data management can be applied for health profession to do quality improvement. cost containment. management information system. and decision support system.

We collect the Korean Database which can be trained for the speech recognition engine in an automotive environment. We describe the overall trends of the Korean database collections in this paper and suggest a database collection method for the speech recognition system of the car-kit and explain several conditions in collecting the database in the automotive environments. Finally, we expain an effective method of the Korean database collection in the automobile and the results of the database colletions, and the devised softwares used for the collection of the database.

This paper presents a geotechnical information system(HGIS) developed for Korea Highway Corporation. To make a database for boring information, characterization study of boring data is carried out. Based on tile study, the HGIS database is developed as a relational database. The HGIS database consists of 23 tables including 13 reference tables. For an effective database management, a boring log program called GEOLOG is developed. GEOLOG can print boring log and store those data to tile HGIS database.

In shipbuilding area, data sharing is one of the crucial issues. Recently, for collaborative design, ship structural CAD systems adopt the database as its primary storage. Database is useful to deal with the large amount of design information among the heterogeneous design department and design stage. To make the database-based CAD system object-oriented database(OODB) and object-relational database(ORDB) can be used. It is important to select proper database because the CAD system performance mainly depends on access performance of database. In this research, using prototype CAD system from other research, access performance of OODB and ORDB form CAD system was evaluated. STEP application protocol was used as the database schema and experiment was made in query by property and query by region. The results give some idea of how to choose the database for CAD systems.

대부분의 상용 데이터베이스 관리시스템은 관게형 데이터베이스 (relational database) 기술에 기반하고 있다. 그러나, 객체지향언어인 EXPRESS로 정의된 IFC(Industry Foundation Classes)를 일반적으로 많이 사용되는 관계형 데이터베이스로 매핑하려면 서로 구조가 달라 미핑과정이 매우 복잡해진다. 한편 IFC를 객체기반 데이터베이스(object-oriented database)나 객채관계형 데이터베이스(object-oriented relational database)와 같은 객체기반의 데이터베이스로 매핑하게 되면 그 과정이 비교적 단순해지고, 많은 장점을 가질 수 있다. 본 연구에서는 장기적으로 IFC와 객체기술에 기반한 통합정보교환기술을 실용화하기 위하여 먼저 관계형, 객체지향형 데이터베이스의 개념에 대해 살펴보고, IFC를 객체관계형 데이터베이스로의 매핑방법에 대하여 알아본다.

The World-Wide-Web have many advantages as a front-end of database systems. Hence in Internet applications, such as E-Commerce systems, the requirements for Web-based database applications have been increasing. In this work we propose a framework for java-based Web database applications-JaWAF(Java-based Web Application Framework). JaWAF has the 3-tier architecture of Client/Server, and consists of database gateway, application server, and communication and message component. When this framework is applied to the database applications developments, it can provide advantages, such as ease understanding and fast implementations of the Web applications. Thus we can build 3-tier Web-based database application systems with high scalability and distributed processing capability. Database gateway in JaWAF works as a daemon process that connects to the database systems and waits for requests from clients, and supports state-oriented service between clients and database servers. Hence the performance of Web applications could be increasing.

In addition to enabling access, database accounts play a protective role by defending the database from external attacks. However, because only a single account is used in the database, the account becomes the subject of vulnerability attacks. This common practice is due to the lack of database support, large numbers of users, and row-based database permissions. Therefore if the logic of the application is wrong or vulnerable, there is a risk of exposing the entire database. In this paper, we propose a Least-Privilege Account Separation Model (LPASM) that serves as an information guardian to protect the database from attacks. We separate database accounts depending on the role of application services. This model can protect the database from malicious attacks and prevent damage caused by privilege escalation by an attacker. We classify the account control policies into four categories and propose detailed roles and operating plans for each account.

In this paper, recognizing the importance of the database query optimization design methods, we implemented mobile database with mobile program (J2ME) which is a useful database procedures. In doing so, we emphasize the logical query optimization which brings mobile database to performance improvement. The research implies that the suggested mobile program (J2ME) would contribute to the realization of the efficient mobile database as the related technology develops in the future.
