The privatization and commercialization of airports has moved forward at the globa1 level. individual countries have begun to focus less on the public welfare aspect of airports, and to emphasize the need to uncover means of increasing their respective airports economic performance and profitability. Although there is a need for Korean airports to be managed in accordance with this global trend. In order to conduct an accurate comparison and analysis of the managerial performances of the fourteen airports, the WLU(Work Load Unit) a concept which integrates the two outputs of airports, namely, passengers and freight, was employed in this study. Furthermore, in order to overcome the limitations of conducting a financial comparison based solely on WLU, the DEA model was also employed to evaluate airport efficiency: moreover, the benchmarking method was used to establish the input-output goals.

Due to the competition between the various professional events, it is imperative for the team's management to improve efficiency by removing the inefficiencies of the professional team in order to gain a competitive edge. This study use different Data Envelopment Analysis (DEA) models to measure the efficiency of professional sport organizations. In this mathematical-analytical study, this study first reviews the related literature to analyze the input/output variables. In the end, the variables were detected and the data for this study were gathered from the Korean Basketball League (KBL). While previous studies examine relative efficiency of Korean Professional baseball teams by using CCR model, this study fully utilize the DEA method to investigate Korean professional sports organizations' operating problem. Thus, this study propose full results of DEA analysis such as efficiency score (overall, technical, and scale efficiency), slacks in inputs and outputs of inefficient organizations, Malmquist index) As a result, this study provides not only the exact productivity information of a team and a way of improving a firm's productivity with a decision maker.

Estimating fishing capacity is one of current hot issues in the international fisheries. It is because that increased fishing capacity has caused not only fish stocks to be reduced, but also additional fishing costs to be incurred without additional incomes, which resulted in decrease of economically viability of fisheries. In order to solve this problem, FAO adopted 'the International Plan of Action for the Management of Fishing Capacity' in 1999 and recommended that member countries to measure fishing capacity and to implement the domestic action plan to reduce excess fishing capacity. This study is aimed at assessing fishing capacity of the octopus coastal trap fishery(OCTF) using data envelopment analysis(DEA) which is a method recommended by FAO. The DEA results on 10 individual OCTF vessels showed that the capacity utilization(CU) was a 0.93 on average, indicating some differences in CU among vessels(0.79-1.0). In addition, results of the sensitivity analysis revealed that under the current level of catch, the gross tonnage, horse power, days fished, and traps per trip could be reduced by 35%, 33%, 16%, and 18% on average, respectively.

In the present emerging global economy, as the focus is shifted from manufacturing to service sector, the efficiency of service operations is crucial for the county's sustainable growth and development. As one of the fastest growing service sector industries in South Korea, the call center has become an inevitable part of customer service for most companies. Despite of the strategic importance of the call center, there has been no empirical study on the efficiency of call center service operations in the literature. The main purpose of this study is to evaluate the technical efficiency of call center services so as to not only identify the current status of call center service operations, but also suggest ways to improve service operations efficiency. For this purpose, we apply a non-parametric efficiency measurement method, DEA (Data Envelopment Analysis), to domestic call centers in order to compare their relative efficiency. Based on DEA evaluations, we provided specific directions for the inefficient call centers to possibly improve their operation efficiencies. It is expected that the measurement methods suggested in this study can be applied to various issues such as service KS certification, service operations management, and the productivity analysis of service personnel.

본 연구에서는 최근에 투입과 산출관계가 복잡한 비영리기관의 운영효율성을 평가하는데 많이 적용되고 있는 DEA분식기법을 이용하여 국내일반은행의 생산성을 상대적 개념에서 측정하고, 은행감독원에 의한 경영평가와 금융감독위원회의 은행퇴출평가 결과를 비교하여 봄으로서 평가결과가 타당성이 있는지 여부를 알아보았다. 금융감독위원회의 평가는 수익성, 건전성, 유동성, 내부유보 등 비율분석에 의한 평가와 BIS비율 등을 고려하여 평가해 왔기 때문에 다산출물 대 다투입물이 상호작용하는 것을 무시하고 있다는 것으로 볼 수 있다. 그리고 은행감독원의 평가와 DEA기법에 의한 경영효율성 간에는 상당한 차이가 있는 것으로 드러났다. 본 연구 분석결과로는 1995년도 효율성 값이 하위 5개 은행은 국민은행, 충북은행, 광주은행, 경남은행, 평화은행이며, 1996년도 효율성 값이 하위 5개 은행은 광주은행, 제주은행, 동남은행, 전북은행, 국민은행, 1997년도의 효율성 값이 하위 5개 은행은 대동은행, 광주은행, 충청은행, 충북은행, 전북은행으로 분석되었다. 퇴출은행 5개중 1996년도에 동남은행, 1997년도에 대동은행, 충청은행만이 효율성 값이 하위 5위안에 포함되어 본 연구의 분석결과와 다소 상이한 결과가 분석되었다. 그리고 DEA 분석모형에 의하면 비율분석에서는 점검할 수 없는 은행의 상대적 경영효율성을 분석한 결과가 금융당국의 평가결과와 다소 일치한 점도 있으나 운영효율성 측면에서 퇴출대상은행이 효율성이 높은 은행으로 평가되어 금융감독위원회가 결정한 퇴출대상은행과 DEA 분석결과와는 상이한 결과가 도출되었다.

The purpose of this study is to evaluate the future potential value of CTE(Critical Technology Element)s that are evaluated to be low in TRA(Technology Readiness Assesment) and to present investment prioritization technologies in defense R&D(Research and Development) based on them. To do this, we used the DEA(Data Envelopment Analysis) method, which is useful in evaluating the efficiency of the organization. Specifically, we suggest a systematic framework to evaluate the future value of CTEs by setting the CTEs derived from the TRA process to DMU(Decision Making Unit)s, the cost and time required to develop each CTE as the input factor of the DEA and the effects of the development of each CTE as the output factor of the DEA respectively. We also conducted an illustrative case study on radar technologies to demonstrate the usefulness of the proposed approach.

Data Envelopment Analysis(DEA) model is a linear programing based technique for measuring the relative performance of organizational units where the presence of multiple inputs and outputs makes comparison difficult. DEA model allows each unit to adopt a set of weight that shows it in the most favorable light in comparison to the other units. The purpose of this study was to evaluate the performance of the libraries of national university in terms of relative efficiency, measured by the method of DEA. Twenty six libraries of national universities in Korea were used to analyze. The number of employees, size of library, budget, and number of books were used for input data, and the number of visitors, number of loan books, and number of books for lending and borrowing were used for output data. We found out that number of libraries with 100% relative efficiency among 26 libraries from 2005 to 2007 were only 9, 9 and 10, respectively. Moreover most of the libraries need to increase outputs and decrease inputs in order to improve efficiency.
