Based on the figure of Program's result, the measurement of National R&D Program efficiency cannot have reflected its characteristic. This study explores the way to integrate evaluators' recognition into program efficiency as a means of embodying its characteristic. As a way of integrating their recognition with evaluating efficiency, two methods are applied. One is AHP as for evaluators recognition and the other is DEA as for measuring efficiency. This study tries to show the effect of evaluators on program efficiency and compares the result with one which did not include their recognition. The study also implies that the recognition of evaluators should be considered when the program efficiency is measured. Furthermore, this study suggests that the participation and role of evaluators should be expanded into evaluation of program efficiency.

This study analyzes 5-year efficiency of the game industry, from 2014 to 2018 which is aimed at 25 online and mobile game companies, that are emerging as a new growth engine of a national economy to come and as a core areas of late entertainment industry. The DEA is used for static efficiency analyze and the DEA-Window is used for dynamic efficiency analyze. This study uses assets, the number of employees and costs as input variables and it also uses operating profits and sales as output variables. The main results show that scale efficiency presents a resonable result over 0.85 on a total average except 2014. However, there has not been a year that is over 0.80 of the whole period in technical efficiency. Also, in terms of business scale, there is a huge efficiency gap between high rank companies and low rank companies and the average trend of efficiency has been increased from 2014 to 2016 but it has been decreased since 2017.

This study suggests consulting directions for non-profit private organizations which were found to be inefficient in the efficiency analysis for the public activities support projects on those organizations performed by the Korean government. An ANOVA analysis on seven types of public activities support projects showed that there were differences among those types. By applying CCB-I, BCC-I, Super efficiency models among DEA, performance efficiencies were analyzed. Four input elements (age of the organization, supported amount, number of members, and the number of workers) and three output elements (project scores, financial scores, and comprehensive scores) were analyzed, and high efficient organizations were found as benchmarking objects, and, through super efficiency analysis, those objects were classified into short, mid, and long-term objects. Through such methods, this research provided organizations with the best information on other organizations to learn from and improve themselves.

We analyze the relation empirically between regional labor market characteristics and job matching efficiency with the adaption of stochastic frontier production function. Our empirical results suggest that, as both the ratio of 50 years-old-job seekers and the level of spatial density increase, job matching efficiencies also rise. In contrast, an increase in the ratio of firms which offer permanent contracts lowers job matching efficiencies. And the job matching efficiency is relatively higher in metropolitan areas. Finally, We find a negative relation between total industrial production and job matching efficiency, which implies that job seekers tend to accept uncongenial jobs in the recessions.

The purposes of this study was to analyze the relative efficiency of nineteen Jeju Self-Governing Schools (JSGS) in elementary level by using DEA (Data Envelopment Analysis). Major results from the study are as follows: First, there were significant differences on the relative efficiency among JSGS, which might come from operation factors rather than from size factors of JSGS. Second, to improve the relative inefficiency of JSGS, it is quite suggestive that satisfaction of both students and parents would be developed, and that the quality of educational programs should be developed by analyzing especially parents characteristics and reflecting their needs. Lastly, the perspective of efficiency, which is a measure of the optimal usage of available school resources, should be adopted and used for school assessment in order to develop the relative efficiency of JSGS.

This paper analyzed the relative efficiency of industrial complexes by type based on the DEA Model. In this analysis, the output and exports of 287 industrial complexes in 2017 were used as output variables, while the industrial land area and the number of employees in the same year were used as input variables. The results of the relative efficiency of industrial complexes by type were as follows: The relative efficiency of industrial complexes was affected mainly by type and the operating period of industrial complexes. In the types of industrial complexes, the most efficient industrial complex was the Urban, high-tech industrial complex, followed by the National industrial complex and the General industrial complex. Therefore, high-tech innovation and government support for industrial complexes would be necessary to increase the efficiency of industrial complexes. In the operation period of industrial complexes, relative efficiencies increased with longer operation periods. To maximize the regeneration effect of the old industrial complex, efficiency must be kept as a priority item of the old industrial complex regeneration project.

With the development of online commercializing technology and the growth of online market, it has become extremely important for companies that aim to commercialize their products and services to control time and resources. Even when a single company has control over the entire process, it is necessary to maintain the efficiency among the process of development. In particular, when there is a lot of cooperation throughout the course of development, requiring many parties to communicate with each other, the issue of declining efficiency becomes much clearer. The timing of when to launch a product or service has become just as important as completing and testing them for companies. Companies have developed new tools to prevent situations that may lead to inefficiency in the development process, including an increase in the amount of resource used or issues with security maintenance. However, there is a lack of proper measurement tool that assesses what kind of additional benefits the entire process of the company is bringing, or whether or not the processes need to be improved in certain areas. Thus, this study aims to suggest a method to measure efficiency, to provide an empirical efficiency measurement method for the development process of online content.

Information and communication industry, which has been growing rapidly, is now leading the global economic growth, contributing a ripple effect on general business and economic structure. It is said that information and communication industry enables swift economic growth taking a role as a basic industry of information-oriented society. Especially, rapid technical innovation promotes mutual growth of other related industries and it is technology-intensive. The purpose of this research is to analyze the management efficiency of information and communication industry using DEA method, and finally suggests numerical value for inefficient organizations to improve their efficiency. CCR-I, BCC-I efficiency and RTS(Returns to scale) of 29 companies engaged in information and communication industry was evaluated. With the results, we suggested the model companies for benchmarking in information and communication industry. To summarize, 7 companies were selected with CCR-I efficiency rate 1, and 12 companies with BCC-I efficiency rate 1. RTS was finalized with 8 IRS companies, 10 DRS companies, and 11 CRS companies.

효율성은 산출물의 가치와 그 산출물을 창출해 내기 위해 생산과정에서 소비한 투입물 가치의 비율로 나타낸다 투입물이나 산출물의 시장가격이 존재하는 경우 이 값을 가중치로 이용하여 산출물과 투입물의 가치를 계산할 수 있다. 그러나 투입물과 산출물의 종류가 다양한 경우에는 투입물의 가치를 적절히 평가하기가 쉽지 않다. Data Envelopment Analysis(DEA)모형은 효율성을 여러 가지 투입물의 가중평균에 대한 여러 가지 산출요소의 가중평균의 비율로 표시하며, 특정 의사결정단위의 효율성 정도는 유사한 투입 산출구조를 가지는 준거집단과 비교하여 상대적으로 측정하고자 하는 방법이다. 본 논문에서는 DEA모형의 구조와 이론적 근거, 그리고 적용상의 장단점에 대해 알아 본 뒤 국내 일선우체국의 운영자료를 토대로 하여 공공적인 성격을 띠는 기관의 운영효율성 측정에의 적용사례를 제시하였다. 투입자료로는 '98년 우정사업자료를 중심으로 공통영업비, 우편영업비, 금융영업비, 직원수, 관할가구수, 관할면적, 고정자산 등 7개 변수와 우편영업수익, 금융영업수익, 보험수지차, 배달 및 중계 우편물량, 현금출납 취급건수, 연평잔실적의 6개 변수를 각각 투입물과 산출물 변수로 설정하여 모형을 구축하였다. 분석대상으로 삼은 64개 우체국 전체의 효율성 평균은 82.14%으로 나타났으며 DEA모형의 효율성결과와 기존에 이미 발표된 정보통신부 평가결과와의 상관관계는 0.46291로 강하지는 않지만 두 변수간에는 정(正)의 상관관계가 있음을 알 수 있었다.
