With the revitalization of alley market area becoming a major goal of the urban regeneration project, an understanding on customer characteristics that affect the sales of alley market areas is needed. As spatial heterogeneity appears to exist in alley market areas, the use of GWR (Geographically Weighted Regression) is required as an alternative to OLS (Ordinary Least Squares) regression. This study analyzes effects of customer characteristics on sales of 1007 alley market areas in Seoul. Comparing R squared and AICc, results show that GWR is better than OLS regression. According to OLS regression, the ratio of female, the ratio of 40's and 50's, the number of employees, the opening rate of establishment, the density of building and the size of alley market area have positive effects on sales, while the ratio of 20's and 30's, the distance of bus stop and that of subway station have negative effects. As a result of comparing local regression coefficients of geographically weighted regression analysis, the ratio of female customers has the greatest effect on the northwestern region, followed by the southwestern region, the central region and the northeastern region. The ratio of 20's and 30's and that of 40's and 50's effect on the southeastern and northeastern regions, and then the southwestern region. It is expected that this study will help to identify marketing target for each alley market area.

Information sharing is one of the key factors enhancing government efficiency and public convenience. However, critics argue that Korean government is now facing various kinds of barriers such as insufficient collaboration among agencies, inappropriate statutes, and technical problems. Thus, this study aims to develop policy alternatives that help resolve the existing problems suggested above. In order to achieve research objectives, this study employs both quantitative and qualitative methods as ways to investigate different dimensions of information sharing in government. Both survey and interview include six dimensions such as organization, technology, culture, management, policy and law. The results show that Korean government needs to implement following alternatives; developing its own database that helps support government decision making, changing organizational culture, continuous extension in terms of the number of object information and affiliated agency, and developing a statute dealing with government information sharing.

Through case studies of photovoltaic complex and wind farm construction and management, the causes of environmental and social conflicts were analyzed. Policies and measures to minimize conflicts and complement the institution were identified by analyzing successful construction and management case studies from both domestic and abroad. The causes of problems were haphazard damages to the regional environment, direct damages from power production facilities, lack of regional benefits from power production businesses, and loose environmental restrictions and management. The countermeasures to mitigate the problems at hand are to improve and strengthen the guidelines for power production businesses, secure residents' acceptability, strengthen regulations for business explanation, increase stakeholder's participation, find alternative sites, and ensure the speedy implementation of on-shore wind farms. Through these countermeasures, specific goals included in the New Renewable Energy Master Plan, such as target goals for photovoltaic and wind energy, preservation and protection of environment, and improvement of residents' acceptability, can be achieved.

도시의 개발을 통한 발전방향은 지역별 기술력을 바탕으로 시대의 흐름과 문화, 경제, 도시정책 등에 따라 다양하다. 특히, 워터프론트는 도시와 가장 근접한 친수공간으로 단어자체에 도시'라는 개념이 포함되어 있다. 즉 도시가 큰 강이나 바다, 호수 등과 접하고 있는 공간을 말한다. 우리나라는 도시계획차원에서 도시 수변공간(urban waterfront)으로 설정하고, 레크레이션, 공원, 경관형성, 환경오염 저감, 정서함양, 생산 등의 다양한 기능을 갖고 있는 매우 공공성이 높은 도시지역의 주요 공간지역으로 의미를 부여하고 있다. 그러나 워터프론트를 개발계획을 수립하는 과정에서 교통계획, 홍수 등의 재해시설, 환경 등에 대한 평가가 제대로 이루어지지 않고 있으며(한국일보, 2011), 개발 계획 추진은 주민 공감대 형성, 사업타당성 검토 없는 '밀어부치기식' 개발 지상주의로 전락하고 있다. 따라서 본 연구는 국내 워터프론트 개발사업 계획을 추진하고 있는 지역으로 인천 송도지역과 부산의 수산시장으로 유명한 자갈치시장 일대의 개발계획, 마산 도시재생지구의 항만 재개발계획 사례를 분석하여 개발계획의 문제점과 언론상에 비춰지는 개발의 현 실태, 지역개발의 효과 등에 대한 시사점을 도출하였다. 사례지역을 비롯한 대부분의 기존 워터프론트 개발은 경제성을 위해 규모가 큰 상업시설 위주로 개발이 이루어지고 있으며, 주거시설이나 문화시설을 비롯한 다양한 시설의 구성이 부족한 특수성을 갖추어 가고 있다. 또한, 기존의 유휴공간을 재개발하면서 도시와의 관계를 제대로 설정하지 못하여 도시와 분리된 폐쇄공간으로 개발이 이루어지고 있으며, 도시구조에 통합되지 못하고 있는 실정이다. 무엇보다 워터프론트 개발사업에 관계된 여러 집단들, 즉 중앙정부, 지방자치단체, 개발주체, 시민 등 이들 사이에 합의 도출의 어려움이 많아 좋은 계획안이 무산되거나 사업이 지체 혹은 중단되는 사례가 많았다. 워터프론트 개발에 대한 지역민사회의 충분한 공감대가 결코 형성되지 않았음에도 오히려 요식적 여론수렴 절차를 강조하고 있으며, 친환경적 도시개발이라는 사업의 목적과 맞지 않는 계획이 많았다. 특히, 관련 사업 중 항만재개발사업에는 막대한 초기 투자비가 소요되어 재개발사업을 위한 자금의 확보가 어려운 경우가 많이 있었으며, 도시의 장기발전계획과 통합된 장기적인 개발전략이 필요한데 이를 소홀히 하는 경우가 있었다. 본 연구를 통해 기존 워터프론트 개발계획의 문제점과 향후 정비계획이 추구해야 하는 친수구역의 관리방법, 주민참여 방안의 대안제시가 이루어 질 수 있었으며, 이를 바탕으로 국내 친수공간 정비계획을 재 고찰 할 수 있는 기회가 되었으면 한다.

There is a Conjoint Analysis to estimate the environmental value of natural river restoration project of Inchon Metropolitan City's small River: Gong-chon Stream, Gul-po Stream, Seung-gi Stream, Jang-su Stream. In order to find out the optimal expense condition, we tried to estimate the possible payable amount. According to the analysis, almost all people are willing to pay 15,000 Won. In case of the river types, the people liked 10 cm's depth of water and there should be brook trail, convenient facilities and flood plain at the stream edge space. But it is impossible to build these facilities with minimum fare 15,000 Won per a household. If the necessary expenses set high, the tax resistance of the local residents will be increased. So, in consideration of the analytical results of the attribute level, we draw five alternatives. This study is based on the results of Incheon metropolitan City residents' survey, and there is Conjoint Analysis to estimate the environmental value of natural-type river project of Incheon metropolitan City. If it is reflected the special assume factors of this study, and if there is exact environmental value estimation of the various river quality through different analysis, then it will become a study of high utilizing.

Recently, various alternatives for safety and efficiency of commercial vehicles have been considered, and one of the new alternatives is the application of a digital tachograph. In Korea, the installation of a digital tachograph to commercial vehicles was regulated from 2011 and Korea Transportation Safety Authority developed e-TAS to analyze the monitoring data from digital tachographs installed in the order of 100 commercial vehicles. This study performs the potential impact analysis of the DTG installation, which includes a trend of dangerous driving, a trend of traffic accidents and cost-effective analysis, a trend of fuel consumption and cost-effective analysis, a cost-effective analysis of social benefits using e-TAS data. Depending on the frequency of dangerous driving, the participants are divided into three groups; high-dangerous group, average-dangerous group and low-dangerous group. The high-dangerous driving group shows lower km/liter than the low-dangerous driving group by 15% for buses and taxis and by 30% for trucks. About $CO_2$ emission, the difference becomes bigger; 25%, 25% and 42% for buses, taxis and trucks, respectively. Although this study is a short-term period analysis, the methodology will be applicable for the long-term period analysis with larger data.

In the recent years, Korean construction companies have been awarded 680 billion USD in the oversea projects which lead to a successful quantitative growth. However, due to the lack of capability in the core technology and project management compared to the leading companies, in addition to low-price bidding, massive deficit projects have caused problems to the companies. In order to overcome the limitations of the lack of capabilities, the term constructability has been researched recently by developed countries to apply in the practical use. The concept of constructability must be applied for Korean companies to compete in the EPC construction projects. The term constructability is defined as the factor that affect the overall construction process of a project which is defined by the ease of construction and to secure the project quality. Therefore, this study aims to develop a constructability assessment model using the structural equation to assess the factors that affect the constructability in the design and construction stage. The purpose of using the structural equation is to analyze the direct and indirect correlation between each factor that affects the international construction projects. Total of 8 latent variables and 34 measured variables are derived through literature review, corporate reports, experts' interview and surveys. The result of the model suggests the constructability factors that are to be managed the most efficiently to reduce cost, time and improve the quality as well as a countermeasure strategy to successfully execute the target international construction projects.
