Credit evaluation by domestic financial institutions on Korean construction companies has had many problems with its tools and criteria ignoring the industrial characteristics. This study develops the DCiF(discounted cash inflow) model as a solution and discusses its usage in construction financing. It also examines the significance of the DCiF indices through regressions and statistical comparison with the other credit evaluation estimates. The results show its clear significance and consistent fitness. Based on the empirical results, implications and methodology are provided for the effective use of the indices in credit evaluation on the construction companies.

In this study, a method for updating the finite element model of bridges with genetic algorithm using static displacement were presented, and verified this method using field test data for PSC girder bridge. As a field test, static load test and pseudo-static load test were conducted, and updated the finite element model of test bridge using each test data. Finally, evaluated the bridge load carrying capacity with updated model using pseudo-static load test's displacement data. To evaluate the bridge load carrying capacity, KHBDC-LSD, KHBDC and AASHTO LRFD's live load model were used, and compared the each results.

This study quantitatively evaluates the economic value of an intelligent crime-zero testbed by using the contingent valuation method (CVM), which is the most effective for non-market valuations in fields like crime prevention. To minimize hypothetical convenience and increase respondents' awareness regarding the actual situation, an analysis was conducted for Indukwon District, Anyang City, Gyeonggi-do, by using the intelligent crime prevention technologies and solutions being developed by the KICT Research Center. This analysis was aimed at providing a systematic basis for determining the feasibility of crime prevention-related public projects. As a result, the WTP of Anyang citizens in the intelligent crime prevention demonstration district was estimated to be 7,160 won. The analysis shows that the area of Gwanyang 2, where the test bed belongs, has a high economic value of KRW 660 million per year, and KRW 51.4 billion per year when expanded to Anyang City. This study is significant in that it provides the first domestic evaluation of the crime-zero testbed. In addition, it has academic and practical value for a future-oriented service model by using intelligent crime prevention technologies and solutions that can be applied in real life and to the crime-zero testbed.

This study evaluated the policy performance of i) Public Notice of Critical Information, ii) Substantiation of Facts in Labeling and Advertising, iii) Temporary Injunctions, and iv) Advertisement Correcting Misrepresented Facts, which were main policies belonged to Fair Labeling and Advertising Act(hereinafter referred to as "FLA Act"). The data was collected by visiting 76 persons personally, who were consumer policy and law experts, labeling and advertising staffs of corporations, and persons in charge of policies including public officials dealing with consumer policies at Korea Fair Trade Commission, while using a structured questionnaire at the same time. The survey was performed to examine the general policy performance and evaluation the results of FLA Act by evaluation methods. The results of the analysis are comprehensively summarized as follows. There were differences in the ranking of policies evaluated by labeling and advertising staffs of corporations and persons in charge of policies according to evaluation methods, and, in Simple Evaluation, higher scores were gained compared to Weighted Evaluation which reflected weighted values or Fuzzy Evaluation. The result shows that evaluation results can vary in policy performance evaluation according to evaluation methods.

웰니스 휴먼케어 서비스의 제공은 최근 2010년 이후에 시작되었으며, 이에 대한 효과평가 혹은 서비스 질 평가는 거의 이뤄지지 않고 있다. 활동량계, 심전도계, 식습관 모니터링 앱 등과 같은 신체적 웰니스 측정 장치와 바이브라 이미지, 맥파/호흡 측정기, 코티졸 측정기 등과 같은 정신적 웰니스 측정 장치들이 개발되고 출시되고 있으나, 웰니스 휴먼케어 제품과 서비스 만족도 측정도구가 없어서 개발 제품과 서비스 만족도를 타당성 있게 측정할 수 있는 도구개발이 필요하다. 본 논문에서는 실증 대상자 면담과 설문 문항에 대한 관련 전문가 내용타당도 검증을 통해 웰니스 휴먼케어 제품과 서비스 만족도 설문 문항을 개발하였으며, 이를 실증사업 참여자 대상으로 시행한 조사 결과 분석을 제시한다.

This study aims to assess the development effectiveness of the Paris Declaration (2005). Using data collected by the OECD/DAC from 78 developing countries for the period 2005~2010, this study evaluates the role played by the Paris Declaration principles alone and in interaction with aid in promoting per-capita GDP growth. The analysis shows that the overall net impact of aid on promoting economic growth has been negative. However, aid effectiveness has been enhanced by the sound policies or institutions and some Paris Declaration (PD) principles. Of the five principles of the PD, only the alignment and, to some extent, mutual accountability principles of the PD did show a significant and positive role in making aid more effective for economic growth of aid recipient countries. Therefore, OECD's statement that the PD enhances aid effectiveness is supported only partially. These findings have significant implications for the importance accorded to sound policies and institutions in the growth literature, and for future international development cooperation agenda.

국제 원유가의 지속적인 상승에 따라 화석연료 고갈을 대비한 대체에너지 및 온실가스배출 감소를 위하여 바이오연료의 시용 및 상용보급은 전세계적인 추세이다. 우리나라의 경우 바이오디젤은 2002년부터 시범보급사업(Demonstration & disseminatio을 거쳐 2000년 7월부터 전국주유소를 통하여 경유 중에 바이오디젤 0.5%를 혼합한 BD0.5를 수송용 연료로 도입하여 아시아 최초로 상용보급화를 시행하고 있다. 또한 휘발유 중 바이오에탄올 혼합 연료유 도입을 위한 실증평가연구를 2006년 8월부터 2008년 7월까지 수행중이다. 자동차용 휘발유의 옥탄가 향상을 위해 함산소 기재로 사용되는 MTBE(Methyl Tertiary Butyl Ether)를 바이오에탄올로 대체한 바이오에탄올 혼합연료유는 수분 혼입에 의한 상 분리(Phase separation)와 금속에 대한 부식성 문제를 야기 시킬 수 있다. 바이오에탄올을 서브옥란가솔린(Sub-octane gasoline)에 혼합하여 상 분리 모사실험, 금속류 부식시험, 고무류 침지실험 등 다양한 품질특성평가를 수행하였으며, 이런 결과들을 바탕으로 국내실정에 알맞은 최적의 혼합량(E3, E5)을 도출하였다. 또한 전국에 4개 시범주유소를 운영하여 바이오에탄올 혼합 연료유의 유통 및 보급을 통해 최적의 유통인프라(Distribution infrastructure) 보완 및 구축 방안을 도출 하고자 한다.
