The high-technological in the electric and electronic industries is recognized in overseas markets as well. However, the competition for technologies in these industries is increasing. Therefore, electric and electronic firms should be more efficient in their production. so, This paper analyzes the efficiency of High-growth Electrical and Electronics firms using DEA model. We evaluate the CCR, BBC efficiency and RTS(return to scale) of 20 Korean high-growth Electrical and Electronics firms. There are a total of 12 efficient DMUs with a BCC of 1. There are a total of 4 efficient DMUs with a CCR of 1. A total of 11 DMUs were IRS in Scale Efficiency and a total of 6 DMUs were CRS in Scale Efficiency and a total of 3 DMUs were DRS in Scale Efficiency. We also suggest the Electrical and Electronics firms which can be benchmarked based on analyzed information.

The research focuses on the provincial universities in the western region of China and investigates the research level of 12 provincial universities from 2017 to 2021, considering both static efficiency and dynamic efficiency. The static efficiency is examined using Data Envelopment Analysis (DEA), while the dynamic efficiency is analyzed using the Malmquist model. The analysis results are as follows: the scientific research efficiency of universities in the 12 western provinces is generally not high. Against the background of the "Double First-Class" construction, the overall efficiency of scientific research in universities is showing an increasing trend. The main reason for the increase in scientific research efficiency is the increase in scale efficiency in recent years. The total factor productivity (TFP) of research activities is influenced by the technology progress index and exhibits a pattern of initial increase, followed by a decline, and then an increase again. Research conclusion: Western colleges and universities should reasonably allocate resources for scientific research activities, perfect scientific research mechanisms, improve management standards, promote scientific innovation and corresponding achievements, and ultimately raise the scientific and technological level in western China.

The purpose of this paper is to measure and analyse the relative efficiency of 17 public libraries in Daejeon metropolitan city using Data Envelopment Analysis. In this paper, total staffs, total area, total holdings are used as library inputs and total circulations, total user visits are used as library outputs. The estimated results show that libraries operate at 64.15% efficiency and only 4 libraries are relatively efficient. Inefficiency of the public libraries was due to small use of outputs compared to inputs.

This paper estimates the relative efficiency of 29 university libraries in Seoul by data envelopment analysis. We employed library space, staff and book collection as inputs, and book circulation and reader visits as outputs. The result shows that average efficiency score is 0.5248 and only 3 libraries are efficient. Inefficiency is estimated to be 47.52%. Reorganization may be necessary in order to achieve greater efficiency.

Container port nowadays becomes one of the most vital link of the transportation chain, plays an important role in trading with other countries. Therefore, evaluating the operational efficiency of container ports to reflect their status and to reveal their position in this competitive environment is very important for port development. Although there have been lots of methods used to measure efficiency in the past, the DEA (Data Envelopment Analysis) model is still the most commonly applied approach. However, the data used in the model sometimes is complex and uncertain to handle using the basic DEA model. In this paper, we applied an uncertainty theory to create an uncertainty DEA model (UDEA), which can solve the limitation of the traditional one. This study mainly focuses on measuring efficiency of 41 container ports by applying proposed an UDEA model. The results show that among 41 container ports, only six container ports are regarded to have efficient operation through the clustering, meanwhile others have technical and scale inefficiencies. We found out that an UDEA model is better to analysis efficiency than existing DEA model.

The study, utilizing a data envelopment analysis (DEA) which is one of the nonparametric estimation methods, aims to evaluate the management efficiency of chestnut tree cultivators in such provinces in Chungchungnam-do as Cheong-yang, Gong-ju, Bu-yeo and so on. The analysis data of this study is based on inputs and outputs of 20 forestry households surveyed in the 2012 survey titled 'A Study on Current Level and Condition of Chestnut Cultivation and Management', which was conducted from March 2012 to October 2012. The elements of inputs are composed of management cost, harvesting cost, material cost, non-operation expenses and cultivation area, while the element of output is a gross margin only. Then the study analyzes a technical efficiency, a puretechnical efficiency and a scale efficiency using CCR and BCC model among DEA methods. Based on that, it also provides improvement methods for forestry households that turned out to be inefficient. In order to verify the result of DEA analysis, the study additionally compares a result of this efficiency study with that of chestnuts management standard diagnostic table. According to the result, the average value of technical efficiency analyzed was 0.667, proving to be inefficient in general. Given that the average value of pure-technical efficiency was 0.944 and that of scale efficiency was 0.703, it can be inferred that inefficiency exists in the field of scale, not in the field of cultivation techniques. As for forestry households with the efficiency score of 1, it is shown that there were 6 households that recorded 1 in the technical efficiency field and 13 households that recorded 1 in the pure technical efficiency. Meanwhile, there were 6 households that recorded 1 in all of the three aspects. In the comparison with the scores from chestnuts management standard diagnostic table, there were 5 households made a high score of over 80, among which are 3 households with score 1 in the technical efficiency. Also, the results of this study and the chestnuts management standard diagnostic table are proved to have the same result, both of them showing the same households that recorded the highest score and the lowest score. This means the management efficiency evaluation using DEA can be applied to the fieldwork along with the chestnuts management standard diagnostic table.

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%.

교육인적자원부는 교육행정 전반의 효율성을 높이고 교원 업무 환경 개선을 위하여 교육행정정보시스템(NEIS)를 시행하고 있다. 그러나 교육행정정보시스템의 도입단계에서 시스템의 보안성 취약과 개인정보에 대한 해킹 우려 등의 이유로 교육행정정보시스템이 정착되지 못하였으나 NEIS의 27개 영역 중 개인정보를 많이 담고 있는 교무/학사, 입(진)학, 보건을 분리 별도의 서버를 구축하는 NEIS 교무업무시스템이 탄생하였다. 따라서 NEIS 교무업무시스템 활용하여 전자문서를 활용하여 이를 통한 교원업무가 경감되어 학교교육행정의 효율성을 모색할 필요성을 느끼게 되었다. 본 연구는 NEIS 교무업무시스템 활용에 따른 교원업무의 효율성을 분석하고자 하였다. 연구결과, 시스템 개선점 도출 및 편리성이 증진되었고 업무조직의 효율적인 분장 및 업무승인을 전자결재로 시행함으로써 시간단축 효과가 큰 것으로 나타났고 교원의 교무업무도 획기적으로 단축시켜 교원 업무의 효율성도 증진시켰다. 또한 교무업무시스템의 활용으로 소요시간과 예산이 절감되었다. 교무업무시스템의 이러한 교원 업무 경감 효과에 비추어 향후 과제를 제시하면 다음과 같다. 첫째, 교무업무시스템의 원활한 운영을 위하여 네트워크 정비나 성능 좋은 컴퓨터가 확보되어야 하고 둘째, 업무 효율화를 위해서 시스템 내에서의 업무 승인 기능이 확대되어야 하며 교원의 업무경감 및 시스템 운영의 활성화를 위해서 훈령을 학교현장의 여건에 맞추어 정비 보완해야 하며, 시스템 운영의 표준화를 위한 제도 개선이 필요하다.
