To investigate the reliability and reproducibility of the computerized cephalometric analysis system, se compared the differences of the 10 linear and 13 angular measurements by manual works and the use of computerized cephalometric analysis system. We obtained as follows : 1. There was not significant difference between maean values of 22 manual and computerized measurements. 2. There was not significant difference between mean differences of manual and computerized cephalometric analysis data taken by same examiner except facial depth, facial length and posterior facial height. 3. There was not significant difference between mean differences of two trials of the computerized cephalometric analysis data by same examiner in all measurements. 4. There was not significant difference between mean differences of the computerized cephalometric analysis data by two examiners except FMIA and IMPA. According to this result, we guess the use of computerized cephalometric analysis system is useful on diagnosis and treatment planning of othodontic patients.

Computerization has been applied in most areas of health care in recent years. But computerized standardized nursing care plans have not yet been adequately developed even though they can significantly contribute to an improvement in the quality of nursing care. Therefore, this study was done to develop computerized nursing care plans. For this purpose, the study had the following objectives ; 1) to develop a computerized program for standardized nursing care plans which include defining characteristics, relating factors, expected out-comes and nursing interventions 2) to test applicability of the computerized pro-grams to the actual clinical situation of the clinical nurse. Application of the system development life cycle by davis was used as the study methodology. There are five stages in this method : strategy planning development, system analysis, system design, system practice and system evaluation. The first four steps in this methodology were used in this project. Two clinical nurses were selected to apply this computerized program in the clinical situation. The results of the study are as follows ; 1) Ten standardized nursing care plans including defining characteristics, relating factors, expected outcomes and nursing interventions which had been proven to have validity in the clinical setting were computerized using the Foxbase Program. 2) These programs were applied to the actual clinical situation by two clinic친 nurses working at Severance Hospital. For further study, continuous revision should be done by the users. Evaluation related to the utilization of the program should also be done.

In order to develop the computerized information system of occupational health management at worksite, we surveyed actual states of computer use at worksites. We used a self-administrative questionnaire to the members of Korean Association of Occupational Health Nursing(KAOHN) from July 4 to August 21 in 1997. Among the members of KAOHN, 147 members answered. The worksites where they were employed were very diverse in aspect of jobs, locations, and size. Occupational health computerized system was used at 30(20.4%) worksites among 147 respondants. When they first introduced the computerized system the most difficult problem was the lack of support of manager. The programs that they have used mainly consist of drug management, health examination management, disease management, but the program of worksite environment management have been rarely used. Most users felt that the computerized system was effective, but there were problems in connection within programs. Many worksites have plans to take or expand the computerized information system within several years. It is necessary to develop the effective and integrated occupational health computerized system.

A computerized chemotherapy order system (CCOS) was developed to improve the accuracy and efficiency of prescriptions for pharmacy medication scheduling at a teaching hospital, Asan Medical Center, Seoul, Korea. We evaluated the system by comparing prescriptions before and after the implementation of the system and by analyzing the effects of the system on dosing accuracy (only against 5-FU), prescription change, overdoses above maximum limit and medication disposal in non computerized program group (control group) and CCOS group. In terms of dosing accuracy, prescription error rate (%) was significantly decreased in CCOS groups compared with the control group. The rate of prescription changes was also significantly decreased in CCOS groups. Regarding overdoses above maximum limit, we found that there was no prescription order exceeding the dosage limit in CCOS groups in contrast to significant overdoses in control group. In terms of medication disposal, there was no significant difference between 2 groups. We suggest that the computerized chemotherapy order system for chemotherapy may bean important and useful tool for minimizing prescribing errors in the hospitals.

The Computerized Procedure System (CPS) is one of the primary operating support systems in the digital Main Control Room. The CPS displays procedure on the computer screen in the form of a flow chart, and displays plant operating information along with procedure instructions. It also supports operator decision making by providing a system decision. A procedure flow should be correct and reliable, as an error would lead to operator misjudgment and inadequate control. In this paper we present a modeling for the CPS that enables formal verification based on Petri nets. The proposed State Token Petri Nets (STPN) also support modeling of a procedure flow that has various interruptions by the operator, according to the plant condition. STPN modeling is compared with Coloured Petri net when they are applied to Emergency Operating Computerized Procedure. A converting program for Computerized Procedure (CP) to STPN has been also developed. The formal verification and validation methods of CP with STPN increase the safety of a nuclear power plant and provide digital quality assurance means that are needed when the role and function of the CPS is increasing.
