세계경제가 범국가적 경쟁에 접어면서 과거보다 지역R&D의 중요성이 강조되고 있다. 국내에서도 지역R&D의 경쟁력 향상을 통해 지역불균형 문제를 해소하고 지역경제발전을 이루고자 하는 노력이 지속되어 왔다. 이러한 문제인식을 바탕으로, 그동안 지역R&D의 효율성을 분석하고 개선점을 도출하기 위한 여러 정책적 학술적 노력이 있어왔다. 본 연구는 지역R&D 효율성을 지식창출과 가치창출의 두 가지 측면에서 진단하고 정책적 시사점을 도출하려는 목적에서 15개 국내 지역의 통계자료를 대상으로 자료포락분석(DEA)을 실시하였다. 본 연구에서 효율성 분석을 위해 사용한 R&D투입과 산출요소의 분포를 살펴본 결과 대부분 수도권과 대전에 양적으로 편중되어 있었다. DEA모형을 분석한 결과, 지식창출 부문의 효율성 점수는 평균 0.869 수준으로 나타났으며, 서울, 대구, 광주, 대전, 강원, 전남, 경북 지역이 효율적이었다. 반면 경남 지역은 0.630으로 지식창출에 있어 가장 비효율이 큰 지역이었다. 가치창출 부문의 효율성 점수는 평균 0.677 수준이며 지식창출보다 지역 간 점수 편차가 컸다. 광주, 대전, 울산, 강원 지역이 효율적인 것으로 나타난 반면 경기 지역은 0.198으로 가장 비효율적이었다. 종합하여 비교하면 광주, 대전, 강원 지역만 지식창출과 가치창출이 모두 1.000점으로 효율적이었고 이를 제외한 지역들은 효율성 개선이 필요하였다. 본 연구는 지역R&D 효율성의 개선방향에 대한 시사점을 제시함으로써 지역발전 정책수립에 도움이 될 것으로 기대된다. 그러나 특정 시점에 한정되어 효율성을 분석하였으므로 생산성 변화에 대한 추가적인 분석과 분석자료에 대한 보완이 필요하다.

This study aims to elevate the usefulness of the current annual Accreditation of Hospitals. To achieve this purpose, A modeling of an efficiency analysis based on DEA and AHP to the Accreditation of Hospitals Data from 2004 to 2008. By applying to AHP and DEA_AR to the scores derived from the various domains in data, An adequate prediction model about conversion factor in fee contract is made. By summarizing information derived from DEA, factor analysis and Generalized Linear Model, The linear functions combining conversion factor and efficiency index is successfully established. The factor analysis with AHP was used to merge diverse scores from the domains of evaluation. Not only the input and output initially introduced, AHP scores, dummy variables of hospital classification, geographical location are effective variables to forecast a conversion factor. If a predicted conversion factors from efficiency is used, It will be a great contributions to the annul doctor's fee contract.

This study is to analyze the efficiency of oriental hospitals using DEA. The input variables are the numbers of doctors, nurses, medical technicians, and beds. The output variables are the numbers of annual inpatients and outpatients. The statistical analysis tools used are EnPas and IBM SPSS Statistics 19. The result in efficiency analysis by establishment type showed that the national and public hospitals had the most efficiency. In the case of location, the efficiency of the oriental hospitals in Seoul was the highest but those in the Metropolitan areas had a relatively low efficiency. If the number of the beds was generally less than 50 beds, the hospitals were highly efficient, but the hospitals in the medium category of 51-100 beds were low in efficiency. The Logistic regression analysis conducted to analyze the variables that have affected the efficiency of oriental hospitals resulted that the efficiency increased by 1.045 everytime the number of nurses increased by 1.

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.

The purpose of this study is to analyze the efficiency of resident companies in port hinterland logistics that are currently operating. The subjects of the efficiency analysis include 13 logistics hinterland resident companies in Incheon Port and Busan Port. Investment amounts, area, and number of employees were selected as input variables, and volume and sales amounts were selected as output variables. As for the efficiency analysis methods, traditional CCR and BCC models were applied. To overcome the limits of these models, a super-efficiency model and a Super-SBM model were also applied. According to the super-efficiency model analysis, the mean was 0.777 and the standard deviation was 0.54, indicating an approximate 33% difference of efficiency among the companies. According to the Super-SBM model analysis, the mean was 0.649 and the standard deviation was 0.489. When considering residuals in the super-efficiency model, the average efficiency score among the companies decreased by approximately 13%. This means that the efficiency score decrease of DMU, where non-radial residuals exist at about 18% on average. Examining the inefficiency of the inputs, the inefficiency of the number of employees turned out to be largest at -45%, compared to 'area' at -33% and 'investment amount' at -33%.

Government R&D support for SMEs is very important and the R&D budget is also increasing. This study suggests a new method for analyzing a performance of R&D programs and analyzes the performance of R&D programs funded by small & medium business administration using the method. We discuss new measures "efficiency" that means short-term performance and "effectiveness" that means long-term performance. Weights based on the R&D programs' characteristics among the various sub-indicators of two measures were derived, and then the final scores were calculated by combining the weights with the responses on the indicators. Finally, this study tests the mean differences between R&D programs statistically. As a results, efficiency of R&D programs shows a significant difference between the R&D programs, while effectiveness does not. Most of the efficiency scores are low, whereas the effectiveness scores are high. The results explain that the R&D programs are managed inefficiently. However, most SMEs predict a positive impact of government R&D supports on effectiveness in the long term. Government needs to try to improve the efficiency of R&D supports because SMEs cannot expect sustainable performance with no improvement in efficiency.

VE aims at reduction in a budget, improvement of function, structural safety and quality security for public construction projects. However, there is possibility for the structural safety and quality security review to be insufficient because related regulations are mostly composed of analysis on economic efficiency of design. In addition, due to the misconception about VE as a cost saving methodology, an alternative is being presented which still focuses mainly on cost saving, but with no objective evaluation of function related to cost. In order to improve this, the government adopted the reduction of life cycle cost and proposal of value improvement, and let people specify the cost and function of the original plan versus the alternative plan, and the value changes between them. However, it is written mainly into practical convenience rather than theoretical basis since a specific way is not suggested. The current method sets a different starting point by applying the attributional difference of function and cost. Furthermore, an evaluation standard for correlating is an important element in rational decision making for assessing and choosing an alternative. This paper analyzes the process and method of function & cost scoring when performing VE and suggests a mathematical normalization model in order to support rational decision making when selecting an optimum plan.

In order to answer the research question of 'how the listed World Cultural Heritage is being managed now?' the indicators of management effectiveness evaluation were set up based on international principles on the basis of the preceding research. The weights and priorities of each evaluation indicators were worked out through the Analytic Network Process(ANP) Technique. Therefore, the evaluation system to evaluate the management status of the World Heritage Sites have been established. Also, through calculate the converted score of 100 points based on the relative importance of these evaluation indicators among the World Heritage Site management effectiveness evaluation index for scoring and the score table was created. When evaluated for the management status of World Heritage Sites to set five rating of the final evaluation score: very deficiency, deficiency, general, good, excellent. According to the results the follow-up study will be carried out in the future.
