The purpose of this study is to analyze the performance difference between public and private hospitals. It is believed that private hospitals may have a better performance compared to public hospitals. The study support the hypothesis. By analyzing 425 acute-care hospitals in Korea, this research shows a less performance of public hospitals compared to private hospitals. Higher labor and administrative cost by public hospitals may account for the difference, and it means they are not effective at cost control. Managers in public hospitals, therefore, should pay attention on cost-reducing issues to regain managerial efficiency of organizations.

Credit scoring is widely used to make credit decisions, to reduce the cost of credit analysis and enable faster decisions. However, traditional credit scoring models do not account for the influence of noises. This study proposes a robust credit scoring system based on Mahalanobis-Taguchi System (MTS). The MTS, primary proposed by Taguchi, is a diagnostic and forecasting method using multivariate data. The proposed approach's effectiveness is demonstrated by using real case data from a large Taiwanese bank. The results reveal that the robust credit scoring system can be successfully implemented using MTS technique.

Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

The political and technological countermeasures to cope with the UR problems are under studying at present or some of them are already applied to increas farm household income. It is evident that the leisture farm development is considered the best alternative among the countermeasures. On account of mitigating labour shortage, a most difficult problem encountered by agriculture, and of promoting consumption of farm products, the leisure farm development could increase farm household incomes accoringly. This study is ultimately aimed at identifing the countermeasures to increase farm household incomes by suggestion of the improvement of leisure farm management thorough survey of the present leisure farm management status. The leisure farm. management survey was carried out based on the seven leisure farms such as Songnam, Cheongrock, Yusung, Duryong, Hwachun, Maesan and Sinhuck which are saperately located in Chungnam Province.

Recently the patient exposure by medical and dental x-ray examination has grown rapidly and diagnostic radiology represents the largest source of man-made radiation. For the patient protection, the principle of justification and optimization should be followed. All the radiographic examinations have to show a potential benefit to the patient weighing against the potential risk. After they are justified, the radiographic exposure should be kept as low as reasonably achievable, taking into account economic and social factors. For the safe use of radiation in dentistry, the radiation safety management in accordance with the legislation is important. The present status and the future of radiation safety management in dental radiology in Korea and other country will be discussed.

Nowadays, a lot of enterprise completed the ERP implementation and these ERP-based enterprises consider the construction of WMS or already have done it. However the enterprises which Implemented WMS linked with ERP have many problems In the warehouse management and the reason ran be summarized In two poults First. In the integration point of view, only Interface issue between ERP and WMS was taken into account, therefore it was hard to reflect the phased process change. Second, a large number of WMS functions were tried to implement at the same tune and these attempts caused confusion and Instability which Is Interpreted as a main reason of the WMS failure. This paper presents the phased construction method for the successful implementation or WMS and in the integration point or view, the phased process change appears naturally

The national Logistics Information system has been rapidly developed on account of the dramatic improvements in the military's logistics support system and supply support system, making a transition from manual work system to computerized work system. Supply level, however, does not reflect these changes in the overall logistics environment and still retains the state it was in the 1970s. This research uses the accumulated data from the equipment maintenance information system developed in the year 2009 to analyze RWT(Requisition Wait Time) and CWT (Customer Wait Time). The analysis estimated the realistic transportation and ordering time and led to the conclusion that the differentiated ASL operation system that considers demand level should be adopted instead of the uniform ASL employment system.

In this study 'forest design in waterside unused land' of 'waterside area' in the specificity that multilateral, including landscape, recreation, social and environmental aspects in the space, taking into account by multiple factors :Raise 'practicality' than a functional management and police to hang out with, each element is usually way to improve the beauty. There is currently carried out waterside green area creation, which is artificial plantation and open spaces only emphasizing 'landscape' with lacking multi-function purpose, as a 'forest design in waterside unused land' strategy but it should be lowered by performance in this strategy. And the study suggested a strategy which prepared cultural and social infrastructure to be able to attract different fund and build local character as an alternative demand plan considered environmental character as a top priority.

In addition to improving economic growth and development of advanced production technology brings many benefits to our society, but if the growth of this still has the shadow of accidents exists. In particular, the construction site has seen a significantly higher accident rate figures despite efforts on disaster prevention. Among the various methods of reducing the need for disaster safety education industry it has become very stressed its importance through many studies. When a disaster causes significant share of the construction industry due to the lack of educational causes, including technical causes, managerial causes, classification and educational causes of this ateumyeo safety awareness and knowledge account for large proportion. In the health and safety education, centered on the subjects of education supervisors will be able to reduce the real and effective industrial disaster education should be run.

This article is to analyze the service efficiency of public sector using Data Envelopment Analysis(DEA). We tried to measure the public service quality and overall satisfaction by using several DEA models, degree of combination and top2box which is a little bit different methodology from traditional ones. We used CCR, Super-efficiency and Slack based measure(SBM) model in DEA to measure public service efficiency of the 16 public institutions(7 City Halls and 9 Provincial offices). Since the traditional method based on the measurement model(CCR, BCC) has the fundamental problems without taking account of the existence of slacks inputs and outputs in several efficient units, we suggest to measure the exact amount of efficiency and inefficiency of the public sector and rank analysis many efficient units exactly through the slacks-based measure model(SBM)
