Purpose: The objective of this study was to collect the basic data for improving the quality of nursing education by identifying the teaching efficiency of the ordered clinical nursing education by preceptor which was accepted by Gachongil College since 2001. Method: The data was collected from 30 Sept to 20 Oct 2002. The subjects of this study were 240 nursing students, junior 2nd term trained by the preceptors and 137 preceptors of 12 hospitals located in Inchon, Gyong Ki-do, and Seoul. The scale for measuring the teaching effectiveness, developed by Kim Miae et al.(1998), was employed as a tool for me study. The data was analysed by SPSS using mean value(SD), and ANOVA. Results: Mean value of teaching efficiency of preceptors evaluated by me nursing students scored 3.68(maximum 5). For 5 causal factors classified en the teaching efficiency, the factor of "teaching method and evaluation" showed the highest score, but "available as resource person" get the lowest. Items showing high score en teaching efficiency were "overall effectiveness of teacher", "was able to work with staff in cooperative manner", but the item of was unclear in instructions given to me showed the lowest. The psychiatric ward get the highest score, but cardiac catheterization room showed the lowest. The hospital 10 showed the highest score, but the hospital 8 get the lowest. Conclusion: As the findings from this study, the ordered clinical nursing education by preceptor showed higher teaching efficiency than the conventional education. Thus, cooperative relationship between nursing colleges and hospitals shall be suggested for improving the quality of clinical nursing education, and ordered clinical nursing education system.

This study used the Data Envelopment Analysis, a mathematical linear programming method, to evaluate cost efficiency of hospitals in Korea. DEA method was applied to 244 hospitals: 31 bankrupt hospitals and 213 survived hospitals. Among the 213 sound hospitals, 11 hospitals showed efficiency score 100, but more than 40 hospitals recorded efficiency scores lower than 60. This result implies that more hospitals can be bankrupt in the restructuring process of the industry within 1-2 years. Among the 31 bankrupt hospitals, the highest technical efficiency score was 0.821 and 11 hospitals showed technical efficiency lower than 0.6. This implies that selective financial support based on cost efficiency by the government will be valuable to prevent bankruptcy of these hospitals. The logistic analysis showed statistically significant relationship between bankruptcy and efficiency of hospitals in Korea.

The objective of this study was to suggest a new efficiency measurement indicator for evaluating the menu management efficiency of decision making units(DMUs) in contract-foodservice operations and to determine the relationship between the DEA(data envelopment analysis) menu efficiency score and menu factors. The results of applying DEA revealed relatively efficient types of service and frequency of meals. The efficient service was shown as a self-service type that operates Monday to Saturday. The considered menu factors included meal price, food cost per meal, meal counts, number of menu items, use of favorite menu use, forecasting error, accuracy of ordering, ratio of inventory, ratio of food loss, use of processed foods and use of prepared vegetables are considered. There were significant correlations between the DEA score and meal price, meal counts, number of menu items, ratio of food loss, accuracy of ordering and use of processed foods respectively. According to the regression results, menu price had a positive influence on the DEA menu efficiency score, and food cost per meal and the use of prepared foods had negative influences respectively.

In this paper we derived the asymptotic relative efficiency, ARE(ms, rs), of our new score function with respect to the McKean and Sievers scores for the asymmetric error distributions which often occur in practice. We thoroughly explored the asymptotic relative efficiency, ARE(ms, rs), of our score function that provides much improvement over the McKean and Sievers scores for all values of r and s under asymmetric distributions.

We propose a new aggressive formulation of cross-efficiency in Data Envelopment Analysis(DEA). In the traditional aggressive formulation, the efficiency score of a test DMU is maximized as the first goal while an average of efficiency scores of peer DMUs is minimized as the second goal. The proposed model replaces the second goal with the minimization of the best efficiency score of peer DMUs. We showed the model is a quasi-convex optimization problem, and for a solution method we developed a bisection method whose computational complexity is polynomial-time. We tested the model on 200 randomly generated DEA problems, and compared it with the traditional model in terms of various criteria. The experimental results confirmed the effectiveness and usefulness of the proposed model.

The study examines the efficiency of private sector banks in India with the help of Window DEA (Data Envelopment Analysis) for a period from 2005 to 2017. With a window of three years, the period was divided into 11 windows. The study outcomes show that 59.9% of all private sector banks in India operate at more than 0.9 level of efficiency, and there are only three occasions when banks were operating at the efficiency value between 0.6 to 0.7. Further, the consistency in the efficiency scores of the banks has also been analyzed using an efficiency mapping matrix, and the mean efficiency score of the bank in each window is studied. The score of standard deviation was interpreted accordingly for these banks. Banks that are showing the highest efficiency scores also have a higher variance of efficiency scores. There was no bank identified in the matrix that promises high-efficiency ratings with low variability. The study concludes that the analysis of the efficiency mapping matrix indicates that, as a DMU escalates in the efficiency scores, the standard deviation reflecting the risk in overall efficiency scores also tends to rise. The findings complement the concept of higher risk to higher return or greater efficiency.

본 연구는 자료포락분석(DEA) 기법을 이용하여 우수감정평가법인의 효율성을 분석하고자 한다. DEA는 복수의 입력과 출력변수를 가지고 상대적인 효율성을 평가하는 기법이다. 우수감정평가법인의 상대적인 효율성을 평가하기 위하여 CCR-O와 BCC-O 모델을 사용하였다. 입력변수는 평가사의 수이고 출력변수는 매출액과 당기순이익이다. 국내의 13개 평가법인을 대상으로 연구를 수행하였으며 2008년 회계연도의 재무자료를 이용하였다. 연구결과는 다음과 같다. CCR-O 모델을 적용한 결과 우수감정평가법인의 기술적 효율성은 약 88.3%로 나타났다. BCC-O 모델을 적용하면 순수 기술적 효율성은 약 90%이고 규모의 효율성은 약 98.2%로 나타났다. DEA 분석결과 비효율성의 원인은 순수 기술적 효율성으로 나타남에 따라 경비절감 등을 통해 순수한 기술적 비효율성을 줄여나가야 할 것이다.

The purpose of this study is to improve effectiveness of Korea's Official Development Assistance (ODA) provided to developing countries. To do this, we analyze the efficiency of ODA provided to 38 recipient countries by Korea through data envelope analysis method. The effects of four factors including population, GDP, economic decline and poverty, and external intervention on efficiency are also investigated by utilizing tobit regression analysis. As a result of the DEA efficiency analysis, it is found that the average efficiency score of the total is about 59%. By region, the average efficiency score of Asia, Africa, Central and South America, and the East and CIS (Commonwealth of Independent States) are about 42%, 68%, 70%, and 74%, respectively. It indicates that the Asian countries are inefficient compared to countries of the other regions. It is also found that factors of population, GDP, economic decline and poverty, and external intervention have statistically significant effects on efficiency at 0.01 significance level. In the case of the population, the higher the population of the recipient country, the more negative (-) effect is on the efficiency. The other factors such as GDP, economic decline and poverty, and external intervention have positive effects on the efficiency.

The Chinese outward foreign direct investment (OFDI) involves various bilateral trade agreements and regional agreements signed between China and other countries. This study examines the impact of Chinese OFDI in ASEAN-5 countries through ASEAN-China Free Trade Agreement (ACFTA) namely Indonesia, Malaysia, Philippines, Singapore, and Thailand from 2000 to 2016. This study attempts to address three research objectives. The first is to examine the motives for China's investment in ASEAN-5. The second is to explore the different impacts of China's investment across countries. The third is to investigate whether the OFDI conducted by state-owned enterprises (SOEs) will produce different impacts on the firm's efficiency score. Using the DEA approach, this study finds evidence that the overall Chinese OFDI is relatively efficient. We find that the estimated efficiency score of this OFDI has improved in pre- and post ACFTA where a higher overall efficiency score was reported when comparing pre- and post ACFTA signing for both SOEs and NSOEs. Finally, China's parent firms' efficiencies showed higher scores among NSOEs compared to SOEs after the signing of ACFTA for all ASEAN countries except Malaysia. We highlight that the country's institutional infrastructure, earlier investment presence, and diplomatic ties help in shaping an effective trade agreement.
