The purpose of this paper is to measure the productive efficiency and competitive strength of Regional Maritime Affairs and Fisheries Office using the DEA. Using EMS(Efficiency Measurement System) which is LP solver, quantifies in one way or another a "distance" to the efficient frontier of the technology. An input oriented measure quantifies the input reduction which is necessary to become efficient holding the output constant. Symmetrically, an output oriented measure quantifies the necessary to become efficient holding the inputs constant. A non-oriented measure quantifies necessary improvements when both inputs and outputs can be improved simultaneously. According to the analysis result of the DEA method, inefficient Regional Maritime Affairs and Fisheries Office should recommend benchmarking reference Regional Maritime Affairs and Fisheries Office in order to enhance the productive efficiency of port administration and a public institution. Besides data on productive efficiency serves as a tool for policy-makers at all levels of activity and is essential for improving the efficiency with which the various systems operate.

R&D investment also has a gestation period similar to other investments in economics. The gestation period originates from time lag effect of input and output. Thus it is necessary to consider time lag effects when analyzing the relationship between firms' R&D investment and R&D performance. The main objective of this research is to estimate the length of time lag effect of R&D investment. The Almon distribution lag model was applied to estimate the time lag effect. The firm level panel dataset was established from 2002 to 2009. The net value of R&D investment and the number of patent applications were used to measure R&D input and output, respectively. This method found the estimated time lag to be 1~2 years across all datasets. The same analyses were applied to chemical, metal, electronic, exact science, and machinery industries' data. And we found there were differences among sectors in regard to the time lag effect.

This Study examines influencing factors such as input, process, and output variables on1 student's satisfaction in cyber-education. That is to study on the effectiveness of input, process, and output variables for cyber-education and how does student's interaction moderate influencing factors and student satisfaction. The study was carried out through literature and empirical study. Questionnaire was used to varify the hypothesis based on which the input-process-output with system models were established. The result of hypothesis verification in this study is as follows : First, learning hour and grade showed a positive influence on the students' satisfaction in learning factors. Second reliant of professor, recognized teaming participate, and contents showed a positive influence on the students' satisfaction in system factors. Third, an interesting findings emerged throughout the analysis, showed that process variables were rather meaning factor than input variables.

모든 기업들의 주요 목표는 경영성과를 얼마나 달성 했는가에 대한 것이 중요시 된다는 것은 모두가 알고 있는 사실이다. 경영성과를 극대화 하기 위해 많은 기업들은 다양한 경영혁신 활동을 도입하고 있다. 경영활동에서 중요한 것은 경영성과의 효과도 중요 하지만 투입 대비 산출 개념의 효율성도 상당히 중요하다. 매년 기업들은 성과에 대한 집계를 통해 관리를 하고 있으며, 경영성과에 대한 효율 측면에 대한 관리도 중요시 되어 관리되고 있다. 경영성과의 효율성에서 투입물은 총자산, 종업원, 운영비 등이 주요 항목이며 산출물은 매출액, 당기 순이익 등이 주요 항목일 것이다. 본 연구에서는 기업들의 경영성과에 대하여 DEA 분석을 통한 경영효율성을 산출하고 기업들의 중.장기적으로 경영계획을 수립할 때 경영성과에 대한 효율측면이 고려 될 수 있도록 연구하고자 한다.

본 연구는 Charnes, Cooper와 Rhodes에 의하여 고안된 DEA기법을 이용하여 서울지역에 소재하고 있는 지역신용협동조합의 운영효율성을 평가하였다. 여기에서는 금융기관은 금융서비스를 제공하는 생산체로 보아 예수금은 산출물로 취급하여, 투입물은 직원수 영업장의 면적(또는 업무용부동산), 경비 등으로 하고, 산출물은 신규예금취급건수, 신규대출건수, 예수금기말잔액, 대출금기말잔액, 영업이익 등으로 하여 DEA모형의 데이터로 사용하였다. DEA에 의한 연구 결과는 기존의 경영평가방법이 제공할 수 없는 유용한 정보를 제공하고 있으며, 이러한 정보를 이용하여 투입물과 산출물을 효율적으로 관리할 수 있다는 것을 보여 준다. 그러므로 DEA에 의한 분석정보와 기존의 경영평가방법에 의한 정보를 적절하게 사용하면 조합들의 운영효율성을 개선하는 데 도움이 될 것이다.

The purpose of this study is price determination for KLIS (Korea Land Information System) which Korea government established. For this purpose, I analyzed cost accounting and made the KLIS selling price according to selling amount, recovery rate and information volume. In case of recovery rate, the cost was expensive but, in case of information volume the cost was cheap. So, the price determination for KLIS should be resonable according to information volume considering GIS revitalization.

The purpose of this research is to analyze the efficiency of the Chinese repair shipbuilding industry using a DEA model with 12 Chinese repair shipbuilding companies. Unlike preceding studies, this study has different research subjects as well as selected input and output variables. The research was conducted with competitive Chinese companies in the market. For the efficiency analysis, input variables included the number of technicians as well as facilities, and output variables were diversified with relevant factors using the number of repaired ships and service ranges as well as sales. The differences were analyzed by including only facilities as an input variable for the DEA model, and then both facilities and technicians. For inefficient DMUs, the strengths and weaknesses were analyzed by finding the causes through a reference group, which was developed into an efficient DMU. Moreover, public and private companies were separated to develop improvement measures.

The purpose of this paper is to verify the two problems(normalization for the different inputs and outputs data, translation invariant for the negative data) which will be occurred in measuring the seaport DEA(data envelopment analysis) efficiency. The main result is as follow: Normalization and translation invariant in the BCC model for measuring the seaport efficiency by using 26 Korean seaport data in 1995 with two inputs(berthing capacity, cargo handling capacity) and three outputs(import cargo throughput, export cargo throughput, number of ship calls) was verified. The main policy implication of this paper is that the port management authority should collect the more specific data and publish these data on the inputs and outputs in the seaports with consideration of negative(ex. accident numbers in each seaport) and positive value for analyzing the efficiency by the scholars, because normalization and translation invariant in the data was verified.

The aim of this paper is to analyze the educational gap between 250 local governments, by their location and size, in terms of the efficiency of education. For the analysis, this paper employed the data envelopment analysis(DEA), which can consider input and output factors simultaneously, as a research method. Input factor included student number per teacher, student number per class, student number per staff, and donation fund per student, whereas college entrance rate and employment rate were used as output factor. The data were collected through 'the school information' website. Research target was confined to high schools, taking into consideration the variables used for output factor. As a result of analysis, while the high schools in local governments around the capital area showed the high density of students in terms of input factor, college entrance rate and employment rate were higher in the high schools of non-capital area. An efficiency score was also higher in the schools of the non-capital area in both aspects of BCC and CCR models. By the size of local governments, high schools in agricultural-type and small-sized local governments were higher in the efficiency of education, compared to those in populated local governments.
