Recently, there has been an increasing need to expand the supply of renewable energy as a solution to greenhouse gas emissions. Therefore, as a measure to promote domestic renewable energy investment and gradual expansion, this study analyzed the investment value of renewable energy projects utilizing the unoccupied spaces of public enterprise's facilities and presented a strategic decision-making framework to support efficient national land development and government measures. The NPV was estimated to be 286 million won if the expansion of the facility was not considered, but it is reasonable to postpone the expansion decision because the value of -130 million won was calculated if the expansion was considered. On the other hand, the real-option value was estimated to be 444 million won, taking SMP uncertainty, expansion, and abandonment options into account, and an additional value of 288 million won was calculated from an analysis of the expansion project using the existing NPV analysis.

The regional environmental conflicts of 'Mungjangdae Hot Spring Development Project' have still now continued from 1985. As a case study, the limitation of environmental litigation and the feasibility of EIA as Alternative Dispute Resolutions (ADR) for solving the conflict of 'Mungjangdae Hot Spring Development Project' was analysed. In order to mitigate environmental and social conflicts, the scope and time of public participation in EIA process which is democratic procedure based on scientific prediction of environmental impact need to be diversified to the extent 'Aarhus Convention', and the burden of environmental litigation need to be alleviated by the 'EIA consultation' from environmental authorities. In decision-making process related with large scale development plan and project which have enormous impact, the effectiveness of the EIA as ADR can be enhanced by applying citizen involvement in environmental governance and the various aspects of sustainability. The effective utilization of EIA public participation such as public hearing to pursue social equity can be a ESSD scheme for the implementation of SDG at regional dimension in Korea.

This study aimed to analyze the effect of New University for Regional Innovation in terms of the users. The evaluation indicators based on the reports of NURI port logistics education project from 2005 to 2009 are overall satisfaction, detailed satisfaction, comparative advantage for from the other universities, continuous employment intention, necessity of re-education, and priority of educational needs and so on. And the percentage of employment was chosen from 2006 to 2009 for the more objective analysis. Analysis shows that the effect of the program is founded because the satisfaction increased gradually and the comparative advantage for from the other universities was higher and the necessity of re-education declined less and less. Especially the program filled the foreign language demands. But it needs to reinforce the links between schools and industries. And also the percentage of employment for the participated departments has continuously increased compared with that for non-participated departments, it shows that the effects of NURI project.

The government recently implemented policies to improve transportation for the disabled passengers. On the other hand, metropolitan public transport still lacks adequate services for these individuals. Many new cities lack urban rail lines and focus on high-floor buses for expansion. Wheelchair users can only access to double-decker low-floor seat express buses for intercity travel. This study examined the necessity and rationale for introducing low-floor seat buses by estimating the user's willingness to pay through a contingent valuation method. Two methods for eliciting the willingness to pay were adopted: open-ended and dichotomous choice questions. The binomial logit model was used to estimate the willingness to pay. The results indicated that the general public is willing to pay an additional 126.7 Korean won, while the disabled passengers are willing to pay an additional 117.5 Korean won. When translated into annual economic benefits, this amounts to approximately 35 billion Korean won.

The Project Delivery System (PDS) is used in mixed way without clear classification from tendering system and the standard itself that can be selected is set with project budget or estimated cost only. Essentially, the PDS should consider and reflect project characteristics and types, internal and external factors for the purpose of improving the lives of citizens and their welfare. However, the current status is not operated flexibly due to the given budget, period and uniform laws and regulations. In order to solve this problem, this study suggests a Decision Support Model to select the optimal PDS for public construction projects. The current problem of the PDS for public construction projects were identified and the application of a decision support model was proposed. Subsequently a decision-making model was suggested for each PDS using the identified factors and linear discriminant function of discriminant analysis. An additional questionnaire survey and actual practical case analysis were carried out to verify the effectiveness and applicability of the model to actual work. It can be used by adjusting the decision support model and detailed factors according to the specific characteristics of public organization, ability of person in charge and project type.

수돗물에 대한 국민적 불신과 불안의 해소는 K-water의 정책목표로서 지난 10여년 동안 추진되어온 중점과제이다. 특히 수돗물에 불신으로 직접 음용하는 비율이 1~6% 내외에 불과하고 이로 인해 많은 사회적 비용이 발생하고 있는 것이 현실이다. K-water에서는 수돗물에 대한 오해를 불식시키기 위해 '14년부터 건강한 수돗물을 공급하는 스마트워터시티(Smart Water City, 이하 SWC) 구축사업을 시작하였다. SWC사업은 권역별로 거점 도시를 구축해 추진 중이며, 북부권(파주시, 송산그린시티), 중부권(세종시), 남부권(부산에코델타시티) 중 수도권지역본부는 파주시를 대상으로 시범 사업을 실시하였고 전국적 확산을 위해 2015년 '건강한 물 공급 확대 및 SWC 구축 중장기 계획'을 수립하였는데 2024년까지 총 2,940억원이 투입될 예정이다. SWC 사업의 지속적인 추진을 위해서는 충분한 재원의 확보가 뒷받침되어야 하며 수도 요금 인상요인도 발생할 것으로 전망되어 이에 대한 대응방안을 마련하는 것도 필요하다. 상수도 요금의 설정방법은 다양하지만, 본 연구에서는 SWC 사업이 위수탁대가 및 상수도 요금에 미치는 영향을 분석하고, "지불의사금액"(Willingness to Pay:WTP)과 함께 가계소득과 가계지출을 기반으로 한 수익자의 "지불가능금액"(Affordability to Pay : ATP)을 추계하여 적정 상수도요금 수준을 검토하고자 한다.

China water market has huge potential for increased use of BOT mode and one of the most attractive markets of doing business. However, the current China water BOT market shows that many foreign companies are retreating from the market while Chinese water companies fast growing. From the view no domestic companies have track records in China BOT water market, the research identified twenty market access barriers in terms of construction laws, regulations, BOT-related policy and the recent market situation. These are evaluated based on interview results with 10 professionals direct or indirect having a China water BOT experience. All the factors are found to be highly influential to foreign company's decision on the market participation. Among those, no fixed return policy and low water price, difficulty in water price adjustment and approval, and no government guarantees, all directly related to the project viability and under the control of government, were the most critical factors, implying government's role is the key in increasing the market competition by attracting more foreign participation on the market. In addition, new construction law regulating foreign EPC contractor's construction work, namely Decree 113, and requirement of applying competitive bidding in selecting EPC contractor in a BOT project are also considered signigicant barriers on foreign participation, which contradicts international norm and therefore necessitates an adjustment on current decision process in domestic companies.
