The improvement project for school zone in Korea is occurring mostly in kindergartens and elementary schools in which children are mainly active, and is being promoted as part of measures to prevent children's traffic accidents. However, since the study on the essential installation facilities and proper level of safety facilities for School zone is lacking, this study relatively evaluated the efficiency of safety facility installation using DEA (Data Envelope Analysis) and suggested improvement plan. We built the facilities and incident data for 28 school zones in Hwaseong City. Six major facilities (Raised intersection, Raised crosswalk, Protective fence, Skid Proof, Speed hump, Speed cameras) that have proven to be effective in the preceding research were analyzed as input factors. As a result of the analysis, only 12 out of 28 showed efficiency and 16 out of efficiency. Effective groups of school zones were found to have fewer installed Protective fences, Skid Proof, and Speed cameras installations than school zones classified as ineffective groups. Protective fences were found to be efficient even if only 47% of the total extension of the school zone was installed, and the number of slip prevention facilities was 8.7 per square km. The number of subjects to be compared is 28, so this study is limited to use as a relative efficiency evaluation index, and it can be grouped into nationwide units and efficiency evaluation can be done for each group.

본 연구는 우려나라 기업집단(企業集團)의 비용함수분석(費用函數分析)을 통해 제조업과 금융업간의 기술적 생산조건을 규명함으로써 제조산업(製造産業)과 금융업겸영(金融業兼營)의 효율성여부를 분석하고, 앞으로의 바람직한 금융소유지배규제정책방향(金融所有支配規制政策方向)을 모색하고 있다. 기업집단의 비용함수분석결과에 의하면 비금융제조업(非金融製造業)과 증권업(證卷業)간에는 범위(範圍)의 경제(經濟)(상호효율증진효과(相互效率增進效果))가 있는 반면 제조업(製造業)과 은행업(銀行業)이나 기타금융업과(其他金融業)의 사이에는 그런 관계가 부재(不在)하며, 우리나라 기업집단(企業集團)들은 평균적으로 규모가 과대하여 비효율(非效率)을 초래하고 있는 것으로 관찰되고 있다. 앞으로 우리 경제(經濟)의 개방화(開放化)와 금융자율화(金融自律化) 그리고 세계경제(世界經濟)의 통합화(統合化)가 진전됨에 따라서 제조업(製造業)과 증권업(證卷業)의 겸영(兼營)및 소유지배관계(所有支配關係)는 지속강화(持續强化)되겠지만 제조업(製造業)과 은행업(銀行業)과의 관계는 오히려 그 연계(連繫)가 약화(弱化)되며, 기업집단(企業集團)의 평균규모도 축소조정(縮小調整)될 것으로 전망된다. 이에 따라 장기적으로 금융소유규제정책(金融所有規制政策)은, 우선은 은행업과 제조업간의 소유지배를 허용하든 금지하든 어느 경우나 뚜렷한 자원배분(資源配分)의 왜곡(歪曲)이나 효율증진효과(效率增進效果)가 나타나지는 않기 때문에, 정부가 특정 소유구조를 강제하기보다는 은행(銀行)이나 기업(企業)들이 자체판단(自體判斷)에 의해 최적소유구조(最適所有構造)를 결정(決定)하도록 하되, 특정 소유지배관계(所有支配關係)의 형성이 금융산업 및 경제내에 경쟁저해적(競爭沮害的) 효과(效果)를 초래하지 않도록 하는 경쟁정책적(競爭政策的)차원에서 접근(接近)하는 것이 바람직할 것으로 판단된다. 그리고 소유집중(所有集中)에 따른 은행(銀行)의 안전(安全) 건전성(健全性) 저해효과(沮害效果)를 방지하기 위해서는 동일인(同一人) 여신한도(與信限度)의 엄격한 운용(運用) 등 건전감독기능(健全監督機能)을 보강해야 할 것이다.

This study aims to provide insights for the efficient utilization of resources by analyzing the entrepreneurship support efficiency of Korean universities. To identify the factors influencing the number of entrepreneurs, which is the primary goal of university entrepreneurship support, a multiple regression analysis was conducted, identifying five effective independent variables. Using these five identified independent variables as input variables and the number of entrepreneurs as the output variable, the DEA method was used to analyze the efficiency of entrepreneurship support for each university as of 2023. The analysis of 150 four-year universities in Korea showed that nine universities exhibited complete efficiency in both CCR and BCC models. Among the remaining 141 universities that showed inefficiency, the cause was scale for five universities, technology for two universities, and both scale and technology for 134 universities. Regarding the returns to scale, nine universities exhibited CRS, 79 exhibited IRS, and 62 exhibited DRS. Additionally, reference groups that could serve as benchmarks for improving the efficiency of inefficient universities were identified, and target values(projections) for each variable to achieve efficiency were also presented. Despite the limitations of the DEA model, this study helps each university identify the causes of inefficiency in their entrepreneurship support and derive specific improvements to enhance efficiency. This facilitates more efficient resource management and can positively impact the ultimate goals of university entrepreneurship support, such as regional economic development and job creation.

The purpose of this study was to examine the efficiency of senior welfare centers and the cause of differences among senior welfare centers in that regard, and to investigate influential factors for the differences in efficiency and the size of the influence of the factors. What methods would be effective at assessing the efficiency of senior welfare centers by taking into account their circumstances was reviewed, andpost-hoc analyses were made by using data envelopment analysis(DEA) and DAE/AP Modified prosthetic which were useful tools to evaluate relative efficiency. After 20 senior welfare centers located in Gyeonggi-do were selected, their yearly operating data of 2009 were utilized. The purpose of this study was to examine the efficiency of senior welfare centers. The evaluation data released by the Gyeonggi Welfare Foundation were analyzed by DEA, which is one of nonparametric statistics, and it was possible to obtain significant results on the regional operating efficiency of social welfare centers in 14 metropolitan cities and provinces, the causes and degree of their inefficiency and what areas one could refer to. As the data for the counties were utilized in this study, it's not quite possible to produce accurate results on the relative efficiency of senior welfare centers, but this study could be said to be of significance in that it suggested how to evaluate the overall operating efficiency of senior welfare centers in the counties involving the degree of their operating inefficiency, what improvements should be made and what reference groups there might be and provided information on the usefulness of the DEA model.
