최근 시설물의 안전 및 유지관리에 관심이 증대되고 있으나, 발주처의 저가발주로 인해 안전진단전문기관은 부실화 되고 부실 점검 및 진단으로 인한 많은 문제점들이 야기되고 있다. 따라서 본 연구에서는 실무자들의 인식조사와 사례분석을 통해 실행대가 현황을 고찰하였으며, 그 결과 정밀안전점검은 대가기준 조정보다는 대가기준의 효율성 증대 및 강제성 강화가 필요한 것으로 판단된다. 또한 정밀안전진단은 연면적 $10,000m^2$미만 시설물에 대한 대가기준 설계금액을 현재 기준에서 80%로 하향조정하고, 그 이상의 시설물에 대해서는 현행 대가기준을 적용하되, 대가기준의 강제성 강화가 필요할 것으로 판단된다.

The optimal design of transmission system expansion planning is an important part of the overall planning task of electric power system under competitive electricity market environments. One of main keys of the successful grid expansion planning comes from optimal reliability level/criteria decision, which should be given for constraint in the optimal expansion problem. However, it's very difficult to decide logically the optimal reliability criteria of a transmission system as well as generation system expansion planning in a society. This paper approaches a methodology for deciding the optimal reliability criteria for an optimal transmission system expansion planning. A deterministic reliability criteria, BRR (Bus Reserve Rate) is used in this study. The optimal reliability criteria, BRR/sup */, is decided at minimum cost point of total cost curve which is the sum of the utility cost associated with construction cost and the customer outage cost associated with supply interruptions for load considering bus reserve rate at load buses in long term forecasting. The characteristics and effectiveness of this methodology are illustrated by the case study using IEEE-RTS.

The purposes of this study were to find factor which influence on the selection criteria of food supplier. Questionnaire were distributed to 52 general hospitals with more than 400 beds located in Seoul and Kyongin province, and responded questionnaires were collected from 44 dietetic departments (84.6%) and 18 purchasing departments (34.6%). The main results of this study can be summarized as follows: (1) supplier selection criteria include quality, service, cost and supplier competency. (2) With having been met with tight competition and market opening, hospitals plan a strategy to improve quality, service and they tend to have more interest in various supplier selection criteria. (3) Purchasing departments estimate more highly the rate of reflection in considering supplier selection criteria than the rate of importance about cost criteria, which reveals that purchasing departments sensitively respond to cost cutdown. (4) When selecting suppliers, a significant(p<.01) influence of stability of supplier industry environment on the selecting criteria such as the importances of quality, service, and supplier quality are recognized only after recognizing the stability of food delivery industry. Food supplier industry secures stability more quickly through major companies' participation in food distribution industry and this will reveal the importance of supplier selection criteria. (5) Suppliers which are selected by the quality criteria, service criteria, supplier quality criteria make efforts to communicate with foodservice departments, to give more proper information about substitute food, new product, and to make commitments, while suppliers which are decided by cost criteria do not establish supportive relationships with foodservice departments.

본 연구는 ROC 곡선에서 형성되는 면적 형태로 나타나는 분류정확도기준인 오분류율곱(multiplication of false rates; MFR)를 제안한다. MFR 기준과 다른 기준로부터 구한 최적분류점의 분류성과에 대하여 비교 분석한다. 다양한 분포함수에 대하여 최적분류점을 구하고 이에 대응하는 FNR과 FPR을 비교하면서 MFR의 특징과 장점을 유도한다. 일반적인 비용함수를 바탕으로 분류점에 대한 비용비율을 다양한 분류기준을 이용하여 구한다. 비용곡선에 대한 비용비율의 관계를 정리하여 MFR 기준의 장점을 탐색한다. MFR 기준의 정의를 다차원 ROC 분석으로 확장하고 다차원의 다른 분류기준과의 관계를 설명하면서 토론한다.

Since its introduction in Korea, design VE has widely been used as a means to enhance values in the construction industry. However, a greater emphasis is still placed on cost reduction in approach attitudes and performance evaluations on the implementation of design VE. In this regard, this study presented a performance evaluation method for cost, function, and value of VE proposals. Numerical criteria on the increase and decrease of cost and function that can classify the value enhancement type of VE proposals were proposed based on the performance evaluation method. It is expected that the use of numerical criteria for the type classification of VE proposal, and cost and performance evaluation method proposed in this study will make it possible to conduct a clear and more intuitive evaluation of VE proposal. However, it is appropriate to use the numerical criteria as a guideline to apply the new performance evaluation method for VE proposals. Therefore, it is necessary to conduct a statistical analysis with a wider range of users after the repeated application of the findings of this study, and thus to carry out research for presenting the numerical criteria for various types of users.

The government has offered incentives to encourage private companies that are to meet the Green Building Certification Criteria. Despite offering these incentives, the Green Building Certification Criteria record share of newly-built building in 2010 is 0.35%, very low. Effectiveness of Green Building Incentive applied by the Green Building Certification Criteria is questioned. So we attempts to analysis about effectiveness of Green Building by using Cost-Benefit Analysis. But if we want to use CBA, we need to draw cost, benefit factors that compose the incentive. So in this study, for applying CBA, we analysis cost, benefit factors.

Purpose : The aim of this study is to review cost analysis methodological issues in the nursing literature. Method : The subjects of this study were articles published in Korea from 1961 to August, 2002. They were searched by key words 'cost' and 'nursing' from various DB(National Assembly Library, The National Library of Korea, RICH etc). Finally, 31 articles were collected. Results : 1) The major type of cost analysis was a cost comparison study. 2) The important methodological weaknesses were as followers: First, many studies did not describe a cost analysis framework or a cost analysis assumption. Second, a few studies described selection criteria of cost items and effectiveness items. Third, many studies did not do a sensitivity analysis. Conclusion : With these results, it will be possible to develop a more proper cost analysis methodological framework and also to make an evaluation criteria for cost analysis nursing study.

공동주택의 건설 분쟁(Claim)발생 시 지속적으로 발생하는 하자의 보수비용 산정 방안에 대한 객관적 기준이 없어 건설전문가들도 각자의 경험과 성향에 따라 다양하게 판단하게 되므로 문제점을 발생 시키고 있다. 따라서 본 연구에서는 이에 대한 분석을 통하여 보수비용 산정기준과 방안을 제시한 후 건축물 하자관련 담당자들에게 합리적인 하자 판단기준을 제안 하고자 한다. 연구결과, 실적공사비를 우선 적용하며 실적공사비에 없는 항목은 표준품셈을 활용하여 산정한다. 지속형 하자 유형인 법규위반 하자의 보수비용 산정은 위반 건물부위만 철거하여 재시공하는 비용을 산정하고, 진행성(확대)하자는 건물 준공의 경과연수에 비례하여 기여율로 산정하며, 반복성 하자는 하자를 최소화시키는 방법의 설비공법을 대안으로 강구하여 산정하고, 가치감소 하자는 내용연수대비 하자보증기간의 비율로 산정하는 방법을 제안하였다. 이중 가치감소하자 보수비용의 산정은 향후 보다 많은 연구가 필요할 것으로 사료된다.

The critical role played by manufacturing performance measurement systems in achieving competitive success is increasingly recognized. Developing an integrated performance measurement model is significant for strategic management. This study consist of several principal steps. Performance criteria from the literature and an questionnaire were utilized prior to building the performance model. The AHP(Analytic Hierarchy Process) is utilized to evaluate the weight of each criterion when generating the performance measurement model for Korea automobile parts manufacturing company. AHP analysis showed clear difference in the priority between 5 criteria and 24 sub-criteria in terms of manufacturing performance of Korean automobile parts manufacturing company. The result of priority evaluation in the 5 criteria of 2nd level was ranked quality, cost, delivery, employee, flexibility. And the critical sub-criteria in the 24 sub-criteria of 3rd level was ranked claim rate, process defect rate, outsourcing parts defect rate, ability to quality management innovation, claim cost, etc.

The investment of BTL(Build-Transfer-Lease) projects for the educational facilities has been increased since 2005. However, many trial errors and problems have been occurring due to the lack of inspection criteria in maintenance cost for the lift cycle of the facilities. Thus, purpose of this study is to derive regression equation for the daily inspection and the regular inspection through analysis of CAD data in order to set the inspection criteria. It is possible to calculate economical maintenance cost of BTL project in educational facilities using criteria of inspection time through the regression equation developed in this study.
