It is quite difficult to analyse the profit that can be obtained from tree plantations because very many factors are involved. However, for giving sound guidelines to forestry enterprices, it is beneficial in calculating the cost ratios. The present author has made some predetermined assumptions for this calculation relating to larch plantations. According to the results, to insure a sound enterprice, the rate of the annual compound interest should be less than 8 percent taking into consideration the risk ratio. It is true, however, that we do not always depend only upon profit analysis results in forest management.

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.

In this study, analysed the characteristics of power drop and surface damage in solar cell through high temperature and humidity test in the 3 case of EVA(ethylene vinyl acetate) and 2 case ribbon thickness. The solar cells were tested during the 500hr in $85^{\circ}C$ temperature and 85% relative humidity conditions, that excerpted standard of PV Module(KS C IEC-61215). Through the EL(Electroluminescence) shots, specimen's surface have partialy damaged. Before and after high humidity and high temperature test, ribbon thickness $200{\mu}m$ EVA1 case power drop rate was 8.463%, EVA2 case was 6.667%, EVA3 case was 6.373%. In the ribbon thickness $250{\mu}m$ EVA1 case power drop rate was 6.521%, EVA2 case was 8.517%, EVA3 case was 6.019%. EVA3 case was the lowest power and FF(fill factor) drop rate at the 2 case of ribbon thickness, because EVA3 is laerger than EVA1 and EVA2 in thickness, elongation and tensile strength.

This study analyzes the economic effect of introducing the arrival duty - free shop at Incheon International Airport. Based on the estimated sales of KRW 127 billion for the duty-free shop at the port of entry, the international balance of payments was estimated at KRW 55.5 billion. Job creation was estimated at 530, including direct and indirect workforce. With the admission of arrival duty-free shops, duty-free shops in the airline are likely to see a decline in sales, helping to improve monopoly structure on the market structure side. It is expected that the rental income generated through the operation of the arrival duty-free shop will be used as a resource for social contribution activities, creating additional social economic effects.

The separation policy of prescription and drug dispensing which has been implemented since the 1st of July, 2000, has brought about great changes in patients flow within the healthcare delivery system. The changes in the patients flow, in turn, resulted in the change in the distribution of financial resources among the participating entities in the healthcare delivery system: pharmacies, clinics, small hospitals, general hospitals, and teaching hospitals. The purpose of this study is to shed some light in the change in the financial performance of teaching hospitals under the separation policy that has created environmental changes such as the decrease in the number of out patients visits, the increase in the capital expenditures, the rapid increase in labor costs and so on. For the purpose, this study has compared and analyzed the balance sheets, the income statements and other operational data of three teaching hospitals located in D area. The data include two periods: before(year 1999) and after(year 2001) the implementation of the separation policy. The analysis was conducted with an emphasis on the changes in the financial ratios such as liquidity, turnover ratio, performance ratio. and capitalization ratio. The results show that the financial performances of the hospitals under study were weaker than before the implementation of the separation policy, and that, while the operating expenses have increased remarkably, there was no tendency to corresponding increase in revenue. And the result of analysis of other operational indicators also show that the performance of the hospitals is getting worse. Based on the results, this study has suggested the directions of the healthcare policies. This study suggests to improve the current model of separation of prescription and drug dispensing, to grant subsidies for the training of residents in teaching hospitals, and to lower the rate of patients' out of porket payment in teaching hospitals.

경영성과(經營成果)의 평가지표(評價指漂)는 개별조직의 목표와 제약환경, 즉 이용가능한 자원량과 개별적 특수요인 등을 고려하여 설정하여야 하며, 산업내의 특성과 동질적 비교집단을 이해함으로써 조직의 성과와 직접적으로 연결될 수 있어야 한다. 또한 조직의 평가는 부분적(部分的)인 효율성(效率性)에 편중되지 않고 투입과 산출간의 유기적인 관계를 총체적인 관점에서 분석함으로써 종합적(綜合的) 효율성(效率性)에 그 촛점이 두어져야 한다. 이러한 문제의 인식에 바탕을 두어 본 연구에서는 Charnes, Cooper와 Rhodes(1978)에 의해 처음 개발되어 주로 비영리기관의 경영성과의 평가에 많이 사용하여 온 DEA(Data Envelopment Analysis)기법을 이용하여 금융기관(金融機關)의 효율성(效率性)을 평가(評價)한다. 금융기관은 다양한 투입요소를 사용하여 다양한 서비스 상품을 제공하는 조직이기 때문에, 또 재무비율을 이용한 기존의 평가나 통계적 생산함수의 추정에 의한 평가방법은 단순히 과거의 실적을 평가하는 데 그치게 되고 객관성이 결여되기 쉽기 때문에 조직의 미래운영방향의 설정에 도움이 되지 못한다는 단점을 가지고 있다. 그러나, DEA은 다수의 투입과 산출요소를 요구하는 경우에 적합하게 설계된 분석방법이므로 금융기관의 성과분석에 적절하게 이용될 수 있다. 본 연구에서는 먼저 금융기관(金融機關)의 효율성(效率性)을 평가(評價)하는 기존의 방법을 간략하게 검토한 다음, DEA에 관한 이론적 기초와 그 특성을 검토한다. 실증분석에서는 여 수신업무(與 受信業務)를 수행하고 있는 국내금융기관들 중에서 자료의 동질성과 표본대상 기업의 수를 고려하여 은행업(銀行業)과 투자금융업(投資金融業)을 선정하고 이들 업종에 속한 37개 회사들에 대한 운영효율성(運營效率性)을 측정한다. 투입요소로 직원의 수와 영업비용을, 그리고 산출요소로 영업수익과 경상이 익을 선정하고, 3년간의 자료를 사용하여 실증분석을 한다. 분석의 결과에 의하면, 18개 전체 은행의 평균적인 효율성의 정도는 가장 효율적인 은행을 기준으로 할 때, 약 85% 수준에 그치고 있어서, 나머지 대부분의 은행들 특히 대규모 시중은행들의 경영상의 개선의 여지가 매우 크다고 할 수 있다. 5대 시중은행들간에는 효율성의 차이가 거의 없는 반면, 지방은행들간에는 매우 큰 차이가 있는 것으로 나타난다. 이는 영업지역의 제한으로 인하여 지역경제 규모가 은행의 수지상황에 결정적인 영향을 미치고 있다는 것을 반영하고 있다. 29개 단자회사를 대상으로 한 투자금융업의 경우에도 은행업의 경우와 동일하게 낮은 효율성과 지역간 격차현상이 나타나고 있다.
