Recently, traceability systems are introduced as a new food safety information system. To trace food products efficiently, they must have an automatic identification capability at the individual product level. This capability can be gained through RFID technology. But there is not yet any performance evaluation tool on RFID-based traceability systems (RFID-TS). This study developed an evaluation tool of RFID-TS. To develop the tool, this study considered the objective and the components of RFID-TS as their performance constructs. According to Churchill's paradigm, the tool was established through two stages. The final evaluation tool consisted of four constructs (risk, operational benefits, IS (information system), and network) and nine sub-constructs. Among the four constructs, risk and IS were found as the most important performance constructs through regression analysis. Among the nine sub-constructs, service (which belonged to the IS construct) and economic risk (which belonged to the risk construct) were found as the most important performance sub-constructs.

Nonlinear analysis for seismic performance evaluation of existing building usually takes 4~5 times more than linear analysis based on KBC code. To obtain accurate results from the nonlinear analysis, there are a lot of things to be considered for nonlinear analysis modeling. For example, reinforcing layout, applied load and seismic details affect behavior of structural members for the existing building. Engineer-oriented computerized system was developed for engineers to evaluate effective seismic performance of existing buildings with abiding by seismic design principles. Using the engineer-oriented program, seismic performance evaluation of reinforced concrete building was performed. Nonlinear hinge properties were applied with real time multiple consideration such as section layout, section analysis result, applied load and performance levels. As a result, the building was evaluated to satisfy LS(Life Safety) performance level. A comparison between engineer-oriented and program-oriented results is presented to show how important the role of structural engineer is for seismic performance evaluation of existing buildings.

리모델링은 노후화, 진부화된 특정건물의 기존상태에서 노후화와 진부화를 극복한 새로운 상태로 변화시키는 건축행위이다. 또한 리모델링은 건축물의 물적 사용 연한을 증가시키기 위한 수단이기도 하지만 사용상의 변화 즉 사회요구변화, 용도변화, 기술의 발달 등의 변화에 대응하기 위한 방안이라고도 생각할 수 있다. 리모델링 공동주택의 성능평가는 우선 리모델링 전 후의 주택 성능과 상태를 파악한 후 그 차이를 비교하여 성능향상 정도를 객관적으로 나타낼 수 있어야 한다. 이에 본 연구는 공동주택의 리모델링 전후의 건축물 변화를 객관적으로 평가할 수 있는 평가체계를 제시할 목적으로 국내 외 및 일본의 성능평가 및 성능인증 제도를 비교 분석하여 리모델링 공동주택의 성능평가체계를 구축하고자 한다.

Today, a great effort to develop PBSD procedure to be utilized in Korea is given by domestic structural engineers, academics, and governmental organizations. After Great East Japan Earthquake (2011) took place, lots of clients in Korea became to concern of their buildings so that requests of seismic performance evaluation and seismic rehabilitation for existing buildings have been gradually increased. Such interests in seismic events initiated a rapid development of a series of guidelines for seismic performance evaluation and seismic performance enhancement. For new buildings, however, design guidelines for PBSD are yet well prepared in Korea and prescriptive design methods are dominant design procedure still. Herein, seismicity demands used in seismic performance evaluation and some important design parameters in NLRH are introduced. Some project examples for seismic performance evaluation and rehabilitation applying passive energy dissipation devices are also described in the latter part of paper.

Infrastructure is provided to the user through long-term project period and large-scale working expenses. Existing facilities are getting old as time goes by. Accordingly, proper maintenance is required and generally more maintenance cost than initial invested cost is needed during life cycle. Therefore, a specific plan that just increases the value of facilities is required by evaluating performance of facilities and inputting minimum maintenance cost. Value engineering that increases the value of object by systemically analyzing Life Cycle Costs and function is actively promoted at the design phase of construction. These efforts can increase the performance of facilities at the maintenance phase of infrastructure. This study is to search how to evaluate the performance of Roadway by utilizing function analysis, as a core part of VE in the maintenance phase. In order to this a new evaluation criteria were proposed by adding an evaluation items to the existing criteria through the research of old documents, status of roadway maintenance and function analysis of VE. The results of this study may promote the effective performance evaluation to determine a resolution of roadway congestion in future. A succeeding study using the proposed evaluation criteria will be required.

The probability and the reliability-based seismic performance evaluation procedure proposed in the FEMA-355F was applied to a reinforced concrete moment frame building in this study. For the FEMA procedure, which was originally developed for steel moment frame structures, to be applied to other structural systems, the capacity should be re-defined and the factors reflecting the uncertainties related to capacity and demand need to be determined. To perform the evaluation procedure a prototype building was designed per IBC 2003, and inelastic dynamic analyses were conducted applying site-specific ground motions to determine the parameters for performance evaluation. According to the analysis results, distribution of the determined capacities turned out to be relatively smaller than that of the demands, which showed that the defined capacity was reasonable. It was also shown that the prototype building satisfied the target performance since the determined confidence levels exceeded the objectives for both local and global collapses.

As an interest in the efficiency of public sector expenditures has spread across the world, Korea has operated a self-evaluation system for government projects as a part of the performance-based budget system. However, an evaluation system for public information technology project has been criticized for its lack of validity, which stems from the uniformity of performance management. This study draws insight from knowledge management literature in an attempt to address the problems with the extant performance evaluation system in public agencies. To realize benefits from IT investment, an agency needs to develop its own performance management model for information systems projects, with a focus on the interaction of IT and organizational system. The knowledge management-based framework for IT projects was verified through a case study, with which we discussed the applicability of knowledge management to the evaluation of public information systems projects.

현대전쟁에서는 군사적 승리가 곧 정치적 승리로 연결되지 못하므로 민군작전의 중요성이 더욱 대두된다. 따라서 우리군은 2014년부터 "민군작전모의모델" 체계개발 사업을 수행중에 있다. 민군작전은 민간인을 대상으로 실시하는 비군사적 작전으로서 민군작전 수행결과에 대한 평가를 통한 지휘관 결심 결과에 따라 민군작전 수행방향을 결정하게 된다. 따라서 민군작전 수행수준에 대한 평가를 실시하는 것이 "민군작전모의모델" 체계개발의 매우 중요한 요소로 판단되어 이에 대한 모의방안을 연구하게 되었다. 어떠한 상황의 발생은 민군작전 수행수준에 영향을 주고 상황조치를 위한 민군작전 수행의 결과는 민군작전 수행수준평가 5대 요소(행정수준, 치안수준, 기반시설수준, 인도적지원수준, 우호도)중 관련된 요소로 평가되고 평가결과는 다시 새로운 민군작전 수행 및 새로운 상황 발생에 영향을 주게 된다. 본 논문에서는 민군작전의 수행결과를 민군작전 수행수준평가 5대요소로 어떻게 평가하고 평가결과를 어떻게 활용할 것인가에 대한 모의방안을 제시하였으며 이러한 민군작전 수행수준평가 모의방안을 활용하여 "민군작전모의모델" 체계가 개발되면 우리나라 실정에 맞는 평가요소들이 반영된 모델로써 민군작전 분야의 연습훈련에 크게 기여할 것으로 기대된다.

Recently, natural disasters due to abnormal climates are frequently outbreaking, and there is rapid increase of damage to aged agricultural infrastructure. As agricultural infrastructure facilities are in contact with water throughout the year and the number of them is significant, it is important to build a maintenance management system. Especially, the current maintenance management system of pumping and drainage stations among the agricultural facilities has the limit of lack of objectivity and management personnel. The purpose of this study is to develop a performance evaluation model using the factors related to performance degradation of pumping and drainage facilities and to predict the performance of the facilities in response to climate change. In this study, we focused on the pumping and drainage stations belonging to each climatic zone separated by the Korea geographical climatic classification system. The performance evaluation model was developed using three different statistical models of POLS, RE, and LASSO. As the result of analysis of statistical models, LASSO was selected for the performance evaluation model as it solved the multicollinearity problem between variables, and showed the smallest MSE. To predict the performance degradation due to climate change, the climate change response variables were classified into three categories: climate exposure, sensitivity, and adaptive capacity. The performance degradation prediction was performed at each facility using the developed performance evaluation model and the climate change response variables.
