A carbon capture and storage (CCS) plays a very important role to reduce $CO_2$ dramatically in $CO_2$ emission sources which are distributed throughout various areas. Numerous research works have been undertaken to analyze the techno-economic feasibility of planning the CCS infrastructure. However, uncertainties such as $CO_2$ emissions, $CO_2$ reduction costs, and carbon taxes may exist in various impact factors of the CCS infrastructure. However, few research works have adopted these uncertainties in designing the CCS infrastructure. In this study, a two-stage stochastic programming model is developed for planning the CCS infrastructure under uncertain operating costs and carbon taxes. It can help determine where and how much $CO_2$ to capture, store or transport for the purpose of minimizing the total annual $CO_2$ reduction cost in handling the uncertainties while meeting the $CO_2$ mitigation target. The capability of the proposed model to provide correct decisions despite changing the operating costs and carbon taxes is tested by applying it to a real case study based on Korea. The results will help to determine planning of a CCS infrastructure under uncertain environments.

본고는 미 일 원자력 협력의 구체적 사례 연구를 통해 일본이 미국으로부터 원자력의 신뢰성, 투명성 확보를 위해 어떠한 노력을 해왔는가를 살펴봄으로서, 한 미 원자력 협력에의 반면교사를 도출하는 것을 목적으로 하고 있다. 특히 핵무기 비보유국으로서는 유일하게 대규모 상업적 재처리시설을 가동 중인 일본이 어떠한 과정과 방법을 통해 로카쇼무라 재처리시설의 가동을 이루어 냈는가를 고찰하였다. 아울러 1990년대 이후 미국의 핵비확산 정책에 어떻게 대응하여 왔으며, 일본의 국제적 원자력 투명성 제고를 위해 어떠한 노력을 하고 있는지를 대미 원자력협력을 통해 살펴본다. 한 미 원자력협정 개정을 준비해야 하는 우리의 입장에서 일본의 경험은 매우 귀중한 연구 자료가 된다. 물론 일본의 원자력이 기반하고 있는 상황과 조건이 우리의 그것과는 상이하다 하더라도, 일본의 대미 원자력 협력의 상세, 일본이 미 일 원자력 협력을 통해 이루어 낸 성과 등은 우리에게 소중한 반면교사가 될 것은 분명하다. 이러한 관점에서 본고는 일본의 경험이 우리에게 주는 시사점을 결론적으로 도출하고 있다.

경기도 김포시의 변화가 예사롭지 않다. 한강신도시가 들어서면서 신흥 주거지로 명성을 높이더니, 이제 경인아라뱃 사업이 본격화됨에 따라 산업계의 시선 역시 집중시키고 있다. 경인아라뱃길 사업이 산업계의 주목을 받는 가장 큰 이유는 김포터미널(김포 고촌읍 전호리 일대)에 조성될 '김포물류단지' 때문이다. '김포물류단지'의 북측에는 마리나를 중심으로 관광, 레저 및 수변상업시설이 배치된다. 또 남측에는 컨테이너 부두와 연계한 장고 집송시설 등 물류시설이 들어선다. 가히 문화와 산업이 어우러진 수도권 서부지역 최대의 물류소통 전진기지가 등장하는 것이다. 이 전진기지의 중심에는 삼성에버랜드가 시공하고 있는 '수도권 통합물류센터' 가 있다. 이 센터는 연면적 $63,571m^2$의 물류창고로, 김포물류단지 내에서는 최대 규모를 자랑한다. 즉 김포물류단지를 대표하는 건축물인 셈이다. 때문에 삼성에버랜드는 큰 책임감과 자긍심을 갖고 시공에 임하고 있다. '철저한 안전관리' 로 김포물류단지의 랜드마크를 선보이겠다는 이곳 현장을 찾아가 봤다.

A new urban paradigm that moves from a vehicle-centric to pedestrian-centric culture should be considered to improve the quality of the pedestrian environments for women, children, senior citizens, and disabled persons as well as to promote community unification by providing general movement rights to everyone. This study was implemented to provide decent alternatives to improve street spaces. The street spaces around the Commercial and Residential Area No.1 located in the Administrative-Centered City, Sejong Special Autonomic City, were selected to analyze and define the status of the walkways and the street spaces. Satellite imagery and numerical maps were used to collect geographic data. Practical and actual surveys for the selected sites were performed to analyze the street status and the pedestrian status. Based on the all collected data, analysis results, and literature reviews, the questionnaire was made, and 315 inquiries qualified for analysis. The physical status of all four study sites was the highest level, Grade A, and green open spaces were relatively sufficient. As a result, the factors obtained from the factor analysis have an impact on the satisfaction of the pedestrian streets in the commercial area. The factors are as followed Design > Convenience > Roadside trees and rest areas > Safety > Safety protective facilities > Transportation and information facilities > Continuity > Basic state of road surfaces > Comfortability, and in the residential area: Transportation and information facilities > Basic state of road surfaces > Comfort > Convenience > Continuity > Design > Illumination and crime prevention facilities > Safety > Roadside trees and rest areas.

This research analyzed the effect of a basic environmental facility siting on the difference in land prices using a case study of Jisan sewage disposal plant in Daegu metropolitan city. To do so, two buffer zones were generated around Jisan sewage disposal plant to 400m at an interval of 200m as a setback distance and 822 officially announced individual land prices were acquired from Korea Ministry of Land, Infrastructure and Transport(MOLIT). Paired samples t-test was performed to compare the mean difference in land prices before and after Jisan sewage disposal plant siting. Results show that the mean land price from each buffer zone was slightly increased after the siting and the difference was statistically significant. Also, the results indicate that the mean land price within 200m was lower than that between 200m and 400m before the siting while there was not different in the mean land price for both buffer zones after the siting. Because Jisan sewage disposal plant did not have a stench and a larger capacity and its surrounding areas were blended by commercial and residential uses, a sewage disposal plant siting had little effect on the fall in land prices unlike previous studies. The findings from this research will provide new reference data for local government and local people with conflicting views on the siting of a basic environmental facility.

Based on basic characteristics of urban disasters and their data availabilities in Korea, this study provides risk assessment models which are derived from Cheongju examples. In specific, the application models are confined to fire, facility and escape risk survey results in the paper. For the assessment criteria, major independent variables for the categories of fire include both the frequency levels and the amount of damage. And the degree of facility risk assessment is heavily hinged on both the weighted values of key facilities and their weighted rank-sizes. In the same context, the degree of escape risk assessment is hinged on both the weighted values and the amount of the classification of land. From the empirical configuration, this paper presents that the potential figure of fire risk is relatively higher in the built-up areas within the existing Central Business District where accommodates a number of dilapidated housing units and community-supportive facilities. In contrast, the potential figure of facility and escape risk is higher in both old residential areas and the newly-built apartment complex. In short, the CBD and its neighboring residential areas record a high potential figure in terms of total risk, juxtaposing fire, facility and escape risk all together.

Currently, image of floating architecture has been positively improved based on the normalization of a domestic representative floating building 'Some Sevit'. Features of the floating architecture are as follows: special experience (29.9%)> landmark (27.6%)> enjoyment of marine culture (21.5%)> center for tourism and regional development (16.0%)> eco-friendly space solving global warming (4.8%). Floating building has a distinctive image and at the same time offers a unique spatial experience to the public. Therefore, space design marketing of floating building is a communication process to exchange its spatial identity and image between the local government and the public, the corporation and customers. It is essential for the effective space design marketing that the spatial demands should be reflected into its program such as commercial, cultural and marina facilities. The unification of project leader and operator is also important. The transformed conditions would help the construction market to be active in the future.

This study analyzed the bicycle traffic patterns and identified the influence factors for each traffic purpose using the household traffic conditions survey for Seoul. The results are summarized as follows. First, as a result of surveying the bicycle traffic ratios according to the administrative dongs, there was a difference of 14.2% by region. Second, various personal characteristic variables, such as age, gender, income, occupation, and housing type, affect the bicycle mode choice, and bicycle passage increases when using facilities in residential areas. Third, among the neighborhood environments, the bicycle traffic for commuting purposes appeared to increase more in the areas of higher land use mix and lower crime rates. In addition, the bicycle road density and the inclination of the area commonly affect bicycle travel for commuting, shopping, exercising, and leisure.
