The purposes of this paper are to review the shifts and changes in urban planning environment, and to grasp how the new 'National and Urban Planning Law' accommodates these changes. In order to accomplish proposed schemes, I suggest that the following three details should be considered for the proper way of Urban Planning Information System(UPIS) from the beginning stage. First, new techniques are required to realize the new concepts in 'National and Urban Planning Law' with GIS and constructed DB by NGIS, as planning support systems. Second, the status of UPIS rises to the highest status among land-related information systems. Third, to adapt the UPIS to the decision support system, the restructuring of urban planning itself should be proceeded under considering the changes of concepts, paradigms and techniques.

소수력은 국내의 풍부한 부존량을 바탕으로 과거부터 관심을 받아왔으나 대수력에 비해 상대적으로 낮은 경제성이나 하천에 미치는 환경 생태적 영향 등의 이유로 개발이 활성화되지는 못하였다. 최근에는 기후변화협약(1992)이나 교토의정서(1997) 채택 등으로 온실가스 감축문제가 국제적인 이슈가 되면서 신재생에너지 중에서도 탄소배출량이 가장 적은 소수력발전에 대한 관심이 점차 증대되고 있는 상황이다. 그러나 점차 높아지는 환경수요는 대수력에 비해 상대적으로 환경영향이 작은 소수력발전소 건설에도 문제제기를 하기 시작하였으며, 정부의 자금지원에 의존한 '비싼' 전력생산을 회의적 시각으로 바라보는 측면도 존재하고 있다. 본 연구의 목적은 소수력 개발의 장애요인들을 극복하고 우리나라의 풍부한 소수력 부존량을 적극 활용하기 위한 향후 소수력 개발 활성화 방향을 제시하는 것이다. 이를 위해서 소수력발전소의 레크리에이션 기능 활성화, 주변지역의 지원 활성화, 수리권 문제의 해결, 환경친화적인 개발, 신규편익의 발굴 및 계량화, 등을 주요 방향 및 과제로 제시하였다.

This research focus on estimating the economic effects of TOD system development from the perspective of new market creation, R&D planning cost reduction and increase of R&D projects' commercialization success rates. The research is conducted through simulation and scenario analysis with assumptions about economic effect parameters. Scenario analysis shows that scenario 1 (the application ratio of the new TOD system to total Korean R&D programs' planning is 1.4%) results in total economic effects, 921.3 billion won in 2011 price with B/C ratio 6.15, that scenario 2 (the application ratio is 1.9%) results in total economic effects, 1,250.3 billion won in 2011 price with B/C ratio 8.34, and that scenario 3 (the application ratio is 0.9%) results in total economic effects, 592.2 billion won in 2011 price with B/C ratio 3.95. The research contributed to the prior evaluation of economic validity of "R&D on Technology Opportunity Development (TOD) system" and to cultivating the new methodology of economic benefit estimation in the area of R&D on system development.

The Korean government is considering implementation of the marine ecosystem restoration technology program (MERTP) to analyze the current status of the marine ecosystems and causes for the ecosystem deterioration as well as to eventually establish a master strategic plan for restoring ecosystem functions and preventing ecosystem functional loss. In order to determine likelihood of successful implementation, it is essential to perform an analysis of the economic feasibility of the program. The present study assessed economic feasibility of the MERTP. To this end, the dichotomous choice contingent valuation (CV) method is used. In particular, dichotomous choice (DC) format is employed as a method of eliciting willingness-to-pay (WTP) response to incentive-compatible mechanisms. The study also employed the spike model to deal with zero WTP responses from the DC CV survey. This survey of 1,000 randomly selected households in accordance with the guidelines provided by the National Oceanic and Atmospheric Administration (USA) was carried out nationwide in 2013. And, the respondents were asked in person-to-person interviews about their WTP for implementing the MERTP. The results showed that the annual mean WTP was estimated to be 5,414 won per household. Consequently, the annual benefit from the MERTP would be about 98.6 billion won for the next five years. Economic feasibility assessment utilizing the MERTP investment cost and expansion cost of the value provided that net present value, benefit/cost ratio, and internal rate of return are 337.8 billion won, 5.20, and 65.9 %, respectively, which are bigger than 0, 1.0, and 5.5 %, and that the MERTP passes the cost-benefit analysis.

In terms of loan transactions, mortgage volume secured by housing in Korea is the most important market share. Hitherto housing finance policies are treated as a kind of property pricing policy. So it is time to import financial systems on behalf of the mortgage loan consumers like a mortgage broker. A mortgage broker is an intermediary that brings a borrower and a creditor together to obtain a mortgage loan. The broker takes the application, performs a financial and credit evaluation, produces documents, and closes the loan. Especially mortgage brokers present themselves as specifically acting in the interest of the consumer by shopping on behalf of the consumer for the best product that meets the consumer's needs and financial circumstances. The paper investigates the economic role of mortgage broker, foreign systems focused on USA, UK, Japan, and characteristics of Korean housing finance markets. Finally the paper provides policy recommendations about Korean mortgage broker system composed of licensing type, uniform professional practice standard, educational requirements.

In the area of such a nature-friendly stream improvement, it is not established yet which engineering method is suitable for stream environment, due to lack of technology. Therefore, although nature-friendly stream improvement was done with expensive engineering method, the effect has not been fully confirmed, which results from the absence of overall valuation tool of stream improvement. In this regard, it is necessary to develop and apply comprehensive and diverse valuation methods covering stream functions to the analysis of stream improvement. In this study, we collected data from years' of monitoring on the Gyeongcheon river, which is located in Sunchang-eup, Jeollabuk-do and recently underwent an nature-friendly stream improvement work. Based on the data, we developed a series of valuation methods such as stream naturalness evaluation, life cycle evaluation, amenity evaluation, and economic benefit analysis to consider the environmental function of stream from a comprehensive perspective. Stream naturalness evaluation is a quantitative analysis of how natural a stream is, and includes additional valuation items such as ecosystem and water quality for the purpose of overall valuation, unlike existing research focusing on physical elements and structural characteristics of a stream. We developed a method of stream valuation with life cycle assessment to river reorganization project. Amenity evaluation method was developed as a means to analyze residents' satisfaction with stream improvement through questionnaires. Economic benefit analysis was developed as a means to determine the attributes of environmental water supply, ecosystem, river maintenance, and water quality and predict economic benefits using contingent valuation method (CVM) and multi-attribute utility analysis (MAUA) method in order to analyze economic benefits brought in by stream improvement. It is considered that the four methods developed in this study make possible to conduct an overall and quantitative analysis of stream improvement.

댐에 의한 가장 큰 편익 중 하나는 홍수조절이다. 21세기 들어서면서 전세계적으로 지구온난화에 따른 기후변화로 빈번한 자연재해를 경험함에 따라 국민의 안전과 생명을 위한 업무로서 홍수방어의 중요성은 증대하고 있다. 기후변화에 따른 극단적인 홍수사상은 물관리의 중요성을 증대시키고 있다. 특히 여름철의 홍수를 적절히 방어해야 하는 우리나라의 경우, 물관리의 대표적인 수단으로서 댐 운영은 매우 중요하다. 댐이나 저수지는 홍수피해를 크게 경감시킬 수 있는 가장 효과적인 수단이다. 댐이 없을 경우, 홍수피해가 그대로 경제에 미치게 되지만 댐이 건설되어 있는 경우에는 댐에서 홍수량을 적절하게 조절하여 경제에 미치는 피해를 최소화하는 기능을 수행한다. 본 연구는 2006년 홍수시 충주댐의 홍수방어에 따른 사회경제적 파급효과를 추정하는 모형과 결과를 제시하였다.

There are recently many studies on evaluating the economic value of multi-functionality of rural areas. However, the regional difference of economic value leads a problem of different evaluation on its economic value for each region in its application to government policy. This problem causes an increase in cost because it creates restriction in policy decisions which put their importance on the time of their execution. This study investigates the propriety of value transfer using Meta Analysis after evaluating the social and cultural value of rural areas among their functions based on CVM model. It finds that the regional difference in the willingness to pay is 0.13% to 31.42%.
