The International Oranization for Standardization (ISO) was as created in 1947 to provide assistance to it members in harmonizing national technical standards. Today its role h as changed to produce international technical standards in order to promote trade international In 1998 a new ISO/Technical Committee (TC) 215 was established to standardize the Health informaties worldwide. The efforts have increasingly been intensified through TC 215 activities in formulating international health informatics standards in order to meet the demand from the industry within its member countries for their international trade. The Republic of Korea joined ISO/TC 215 as the P-member body in 1999 unit Korean experts started to participate actively in TC 215 work processes. However, domestic standardization in health informaties is in its infancy Therefore, current activities of ISO/TC 215 and current status of Korean Health informaties Standard Committee base been reviewed to be able to generate interests from experts and technical professionals in the field of health informaties

The purpose of this studs is to evaluate the Scientific soundness. reliability and harmfulness of medical information on world wide web in Korea. We focused this study just in "hepatitis" information, considering the high incidence of this disease in Korea. 689 web pages relating to hepatitis were collected by means of Lycos Korea search engine. and finally 182 web pages were selected. These 182 web paces were analyzed as category (western/oriental/folk medicine and as subject (prevention/diagnosis/treatment/others). Alter this analysis, these web paces were evaluated by investigators composed of two family physicians and one gastroenterologist. They analyzed the information on the criteria of "scientific soundness" "omission/ . exaggeration" and "harmfulness". The major results were as follows: 1. 133 web pages (73.3%) were scientifically sound. But the web pages relating to oriental and folk medicine revealed relatively low scientific soundness. compared with western medicine wet) pages. Also, the scientific soundness revealed low especially in the web pages that mainly described the treatment of hepatitis. 2. The web pages that had the omission of essential information was 9,3% . and those of the exaggeration" was 26% These results were related to the scientific soundness. The rate of the omission was relating high in the web pages related to the folk medicine (34.6% ), and the rate of exaggeration was remarkably high in die web pages related to the oriental medicine (89.5%), Both rates of the omission (20.9%) and exaggeration (67.2%) revealed especially high in the web pages that mainly described treatment of hepatitis. 3. The web pages that had the harmful information was also had the scientific unsoundness. The rate was high in the web pages related to the folk medicine, and the rate of web pages that had direct persuasion of harmful acting was as remarkably high in the oriental medicine. Also these rates were high in the web pages that mainly describe the treatment of hepatitis. This investigation showed that the large part of internet health information about `hepatitis in korea had the scientific soundness, but also revealed there were mails information that could give unhealthy influence to internet navigators it Korea. The most powerful element that could give unhealthy influence to internet navigators was lack of the scientific soundness, and this unhealthy information mainly revealed in the oriental or folk medicine web pages. especially in the treatment information.

The adverse drug reaction(ADR) monitoring is very critical in healthcare. However, the number of actual reported cases on ADR has been extremely low in Korea compared to other countries. This study was designed to find out a way to expedite ADR reporting in a general hospital, where many drugs are used daily. In this study, a newly developed ADR monitoring system has been implemented and was evaluated for its outcome. In addition, a survey was conducted for two groups, 50 ADR reporters and 100 non-reporters, to identify factors which can affect the ADR reporting. The new system was a multidisciplinary program based on a voluntary reporting involving doctors, nurses and pharmacists. The reporting methods were diversified such as ADR report sheet, computerized Order Communication System(OCS) consultation and drug refund reports. After a year since the system has been implemented, the number of reported cases was 158, which was 131 times higher than that of the pre-implementation period. Doctors reported the most(75 .3%), and ADR report sheet was used most frequently(57%). In terms of severity of ADR 74.7% was mild, 22.8% moderate and 2.5% severe. The unexpected ADRs were 7.6%. Both groups had a high degree of awareness of the necessity of monitoring and basic knowledge of ADR. Important factors affecting ADR reporting were frequency of ADR findings(p<0.01), awareness of the fact that the institution was designated as an ADR monitoring institution(p<0.001) and participation in the education program(p<0.01). In conclusion, modification of the reporting system and ongoing and systematic education are needed to improve ADR monitoring in a general hospital.

9.Quality control in Clinical Chemistry by "The Multi-Item Univariate Delta Check Method": The Multi-Item Univariate Delta Check Method.
Journal of Korean Society of Medical Informatics 1999;5(3):119-125
Difficulties in calculation that hindered the practice of the delta check in the past is now no longer a problem thanks to the development of computers. But, high false positive rates, which creates heavy burden of checking-work load, are still a problem in the practice of the delta check. We propose a new approach to the reduction of false positive rates, naming our method "the multi-item univariate delta check (MIUDC) method". By the multi-item univariate delta check method, we mean a method in which univariate delta checks are performed on multiple items and specimens with the positive univariate delta check in at least k items receive a detailed investigation. Using data collected in the Department of Clinical Pathology at Korea University Guro Hospital via the Korea University Laboratory Information System, our research found that if we put specimens with positive univariate delta check in at least four test items (k=4) under a detailed investigation, check-out volumes will be light and efficiency will be high. As for test items deserving of more interest, total cholesterol, albumin, and total protein are appropriate because the false positive rate associated with them in the MIUDC was zero in a simulation study.

Journal of Korean Society of Medical Informatics 1999;5(3):109-118
The integrated management of medical data raised the efficiency of them and improved doctor' s diagnostic ability by processing correct data. Various medical information processing led out the development of new medical technology and is incurring huge changes for the medical examination and diagnosis. In medical database security, both serializability and security must be considered to maintain data consistency and prevent covert channel. In the security environments of heterogeneous medical database systems, the existing local autonomy and the security autonomy as a new constraint are required. This paper defines multilevel secure one-copy quasi-serializability (MLS/1QSR) necessary for concurrency control in heterogeneous medical database systems with replicated data to solve security problem among many objects of medical database systems. The proposed MLS/1QSR neither violates security autonomy nor establishes covert channel for transactions in heterogeneous medical database systems.
