Financial stability is the foremost prerequisite for the continuous growth and development of hospitals. The present study aimed at developing a deterministic model using the factors which affect the hospitals profitability and at discovering which factor affected the hospital profitability. The study conducted questionnaire surveys on all general hospitals, with the exception of special hospitals, with over eighty hospital beds. Of the 274 subject hospitals, 136 of them, consituting 49.6% of the whole, were used in the study. The results are as follows. 1. In the deterministic model, outpatient revenue was affected more by the number of physician visits than by outpatient service intensity. Inpatient revenue was found to be affected more by the number of discharged patients than by inpatient service intensity. However, the increase rate of the service intensity not only contributed in stepping up the operating margin by $4{\sim}8%$ in outpatient and $3{\sim}6%$ in inpatient, but it was statistically significant. 2. Among the factors which determined the operating cost within the deterministic model, the number of patients had a greater impact on the operating cost than the resource consumption per patient. 3. The resource consumption per patient were proved to have the greatest effect on the profitability within the probabilistic model. The management cost per adjusted patient, in particular, was proven to have a statistically significant effect on the profitability in all hospitals.

This study was conducted to verify the current criteria and classification system used to determine specialized general hospitals status. In this study, we proposed a new classification system, which is simpler and more convenient than the current one. In the new classification system, clinical procedure was chosen as the unit of analysis in order to reflect all the resource consumption and the complexities and degree of medical technologies in determining specialized general hospitals. We developed a statistical model and applied this model to 117 general hospitals which claim their national insurance through electronic data interchange(EDI). Analysis based on 984 clinical procedures and medical facilities' characteristic variable discriminated specialized general hospital in present without misclassification. It means that we can determine specialized general hospital's permission in new way without using the current complicated criteria. This study discriminated specialized general hospital by the new proposed model based on clinical procedures provided by each hospital. For clustering the same types of medical facilities using 984 clinical procedures, we executed multidimensional scale analysis and divided 117 hospitals into 4 groups by two axises : a variety of procedure and the proportion of high technology procedure. Therefore, we divided 117 hospitals into 4 groups and one of them was considered as specialized general hospital. In discrimination analysis, we abstracted proportion of 16 clinical procedures which effect on discriminating the specialized general hospital in statistical system, also we identify discriminating function which include these variables. As a result, we identify 2 discriminating functions, one is for current discriminating system, and the other two is for new discriminating system of specialized general hospital.

The purpose of this study was to examine the trends of length of hospital stay (LOS), which is most likely to be a major attribute to hospital performance. From 1984 to 1994, average LOS of each hospital were analyzed according to factors such as medical departments, bed size, occupancy rate, region and ownership. This study findings are as follows: 1) The results indicated that the average LOS steadily increased until 1990 but it slightly decreased after 1990. 2) This trend could be found in all hospital scale and all group of occupancy rate. Specifically this trends of LOS were found in internal medicine, corporate owned hospitals and hospitals in major city. But LOS of individual owned hospital was continuously increased until 1994. Finally from this result we think, that most hospitals in Korea began to be concerned with LOS. Nevertheless LOS of several hospital such as small hospital or individual owned hospital was increased. And this tend may be caused by a fewer patients, low occupancy rate or low profit. This trend of LOS is different from that of other countries. Perhaps this phenomenon results from the reimbursement method. Because of the fee-for-service reimbursement system in Korea the hospitals did not need to shorten LOS in order to save costs and increase profits. Therefore reform of hospital cost reimbursement method will be needed to reduce hospital cost in Korea. We think that the Korean health authority should consider the reimbursement method by unit of bundle of services, for example DRG and prepayment in the United States. This study presents some limitations such as no insight of severity of disease, case-mix measurement of hospital, and other clinical characteristics that can possibly affect LOS. However, this study reports an important trend in the annual LOS from 1984 to 1994.

돈피를 부위별로 분류하여 일반성분, 아미노산, 지방산, 색도, 조직감, 관능평가를 실시하였다. 일반성분은 등 부위를 제외한 부위들이 비슷한 수치를 보였고 아미노산은 앞다리 부위와 뒷다리 부위가 필수 아미노산 함유량이 더 높은 것으로 나타났다. 돈피의 지방산 함량은 부위에 따라서는 크게 차이가 나타나지 않았으며 지방산의 종류별로는 oleic aicd의 함량이 가장 많았고, 색도는 붉고 황색기가 적으며 명도가 높은 등 부위와 배 부위가 높은 수치를 보였고 이는 관능에 영향을 미쳐 명도가 낮고 붉은 황색을 띄는 앞다리보다 높은 기호도를 보였다.

The goal is to improve the national health level in our country. To achieve this how to manage the chronic diseases cost-effectively is very important. Population-based comprehensive Chronic Care Model approach should be arranged in the national health insurance framework. It is necessary that private health promotion services are launched in the market, but we should focus on which way of delivering preventive services can benefit in the future.

Microbial reduction, physicochemical property, and sensory evaluation of irradiated beef patty were investigated. The microbial counts of refrigerated beef patty were reduced to below the number of 3 logs after irradiation at 3 kGy. But no viable microorganism was detected in frozen beef patty irradiated at 3 kGy. Food additives such as nitrite, salt, phosphate and ascorbic acid did not affect on the inactivation of microorganism by irradiation. The irradiation effect on the water holding capacity was not significant, but frozen irradiated beef patty showed higher water holding capacity than refrigerated beef patty. The drip loss of irradiated beef patty did not show significant differences according to irradiation doses. Considering the influence of food additives, the irradiated beef patty mixed with salt and phosphate showed lower drip loss than that without food additives. In refrigerated beef patty, TBARS values were increased with increase of irradiation doses and showed lower values in the beer patty mixed with food additives than that without food additives. The redness of refrigerated beef patty showed highest values at 3 kGy of irradiation and then decreased with increasing irradiation doses, while in the frozen beef patty did not show distinct tendency according to the irradiation doses or food additives. In sensory evaluation, the irradiated beef patty showed unpleasant smell as compared with the non irradiated beef patty, but showed some-what higher score in smell at the sample contained ascorbic acid regardless of irradiation doses.
