Recently, the Ministry of Strategy and Finance announced a plan to reduce the proportion of economic evaluation in non-metropolitan areas and strengthen balanced development evaluation through the reorganization of the preliminary feasibility study system. In addition, the social value of the quality of life, such as job, environment, and safety, which may be affected by the implementation of transportation facility investment projects, was reflected as the main item of policy evaluation. In this study, the ripple effect of the project in terms of social value was reviewed for the Gangil-Chuncheon. The effect of highway opening was investigated by reviewing the feasibility report, post-evaluation report, and statistical indicators. Recently, the Gangil-Chuncheon highway is getting used by around 110,000 people per day. The number of tourists in Chuncheon rapidly has increased from 5 million a year to more than 11 million now. In addition, it was confirmed to produce effects such as population migration, net inflow and land price increase, improvement of living convenience, and expansion of emergency medical care. Although this ripple effect was influenced by various socio-economic factors as well as the opening of the highway, it is clear that it is difficult to occur without the opening of the highway. It is judged that the evaluation of indirect benefits and social values due to the opening of the highway can be quantified through continuous research and data construction. Post-evaluation of construction works, including project efficiency evaluation and ripple effect evaluation, is performed for construction works with a construction cost of more than 50 billion won. In the future, we will continuously improve the evaluation system in order to evaluate the indirect benefits and social values of public investment projects.

The paper deals with the analysis for improving evaluation system of government-supported program in developing engineering college. I think that it is important to consider evaluation system of government-supported program and faculty in the aspect of policy responsibility and autonomy. I suggest three proposals. First, in the perspective of evaluation system of government-supported program, it is important to keep the balance between SCI-based evaluation and practical & University Industry Corporation (UIC) indicator or keep the balance between quantitative indicators and qualitative indicators. Second, in the perspective of evaluation system of faculty, UIC-friendly evaluation system should be expanded and institutionalized. Finally, the evaluation systems should be not only built, but also utilized for developing engineering college.

The strategy for the management of earthquakes is shifting from post recovery to prevention; therefore, seismic performance management requires quantitative predictions of damage and the establishment of strategies for initial responses to earthquakes. Currently, seismic performance evaluation for seismic management in Korea consists of two stages: preliminary evaluation and detailed evaluation. Also, the priority of seismic performance management is determined in accordance with the preliminary evaluation. As a deterministic method, preliminary evaluation quantifies the physical condition and socio-economic importance of a facility by various predetermined indices, and the priority is decided by the relative value of the indices; however, with the deterministic method it is difficult to consider any uncertainty related to the return-year, epicenter, and propagation of seismic energy. Also this method cannot support tasks such as quantitative socio-economic damage and the provision of data for initial responses to earthquakes. Moreover, indirect damage is often greater than direct damage; therefore, a method to quantify damage is needed to enhance accuracy. In this paper, a Seismic Risk Assessment is used to quantify the cost of damage of road facilities in Pohang city and to support decision making.

Purpose: This paper provides a method to identify cost-effective standards by analyzing the relationships between certified company and standards. It also aims to provide a evaluation model to establish a certification portfolio strategy of institutions. Methods: By analysing the networks of certified company and certification standards, this paper developed an evaluation model of standards. The evaluation model uses an index(Certificated Standard Evaluation Index; CSEI) to assess the value of standards. Results: To verify the applicability of the evaluation model, the proposed model and the CSEL index have been applied to certification standards of Korean Standard Association. The results show that the evaluation model can effectively identify potential customers and thereby establish a certification portfolio strategy. Conclusion: The main contribution of this study is a provision of a new approach to certification portfolio strategy by evaluating the value of standards. The proposed model is expected to provide implications for the certification portfolio strategy.

The current evaluation time period for the construction management service is the project completion or after project completion. Therefore, the construction manager has the following problems. First, it is difficult to prepare the evaluation due to the new field movement of the existing participating engineer. Next, the CM work is complex as well as extensive. Therefore, the critical success factors of the construction technology services evaluation are required as a systematic performance standard of CM work. In this study, we extracted the critical success factors that can systematically prepare the evaluation from the early stage of the project through in - depth interviews with experts. And, this study was analyze the priority of each factor by using AHP technique. As a result, the most important factors were related to the systemization of the preparation process, the construction manager work capabilities and practical construction management. And the priorities of all factors were analyzed high in the factors suggested by the owner groups. The results of this analysis are expected to provide the standards that construction management service performer carry out structured management of construction management throughout the project.

This study aims to improve the uniform functionality of the workers who work in Electric Technology Division, Korea Railroad Corporation. Former study of questionnaire survey was taken to examine the current state of wearing working clothes for the workers. Based on the results of the former study, an experimental clothes, the functionality of which has improved in terms of design, materials, and patterns, was created, and existing working clothes and the treated experimental clothes were compared through simulation wearing evaluation comprising appearance, activity adaptability, quantitativeness, and on-site adaptability evaluation comprising appearance and activity adaptability. The followings are the results of the study: Simulation wearing evaluation is composed of 5subjects and 11experts specializing in costume, and as a result of evaluation the experimental clothes were evaluated superior to the existing working clothes in all items. On-site adaptability evaluation was conducted by workers in the Electric Technology Division, who are the subjects in this study. In that evaluation, the experimental clothes were also evaluated superior to the existing working clothes in all items. While the five subjects who participated in the simulation wearing evaluation move, the quantitative evaluation measured the distance of location transfer of the back length in the jacket and the distance of location transfer of the back waist in the trousers. As the distances in the experimental clothes were measured shorter than the distances in the existing working clothes, the subjective evaluation results are objectively supported.

건설공사 사후평가 제도는 공공건설사업 수행결과를 반영하여 향후 유사한 공공건설사업의 계획 수립 시 활용되어져야 하나, 현행 제도는 당초 기획 계획 당시에 추정한 수요, B/C비율, 공사비, 공사기간 등 예측치와 건설공사 완공후 일정기간(3년 내지 5년) 경과후에 측정한 실제 결과치를 단순히 비교하여 제시하는 수준에 그치고 있다. 또한 대부분 공공발주기관에서는 수동적인 사후평가 업무수행에 그치고 있어 제대로 환류가 이루어지않고 있다. 이에 본 연구에서는 공공발주기관을 대상으로 설문조사를 실시하여 건설공사 사후평가 제도의 수행현황을 파악하였으며, 국내 사후평가 제도와 유사한 미국과 일본의 건설사업 평가체계를 벤치마킹하였다. 또한, 건설공사 사후평가 제도와 관련된 국토부 실무담당자와의 수차례 업무회의를 실시하여 사후평가 수행의 적시성 확보 및 활용성 강화방안을 제시하였다. 이와 같이 건설공사 사후평가 제도 개선을 통해 건설사업 수행과정에서의 목표 및 성과에 대한 확인 점검 분석 체계를 내실화하고, 건설공사 특성별로 평가내용 및 방법을 차등화함으로써 발주청의 사후평가 수행에 대한 실천력이 제고될 것으로 기대된다.
