The positive changes in urban space and urban activities resulting from the urban services provided by Smart City is not accomplished by simply creating the physical environment built on ICT but through the cooperation and participation of citizens and private sector, which is in fact key to success. In this study, this research analyzed the role and structure of smart governance, which is a system of horizontal cooperation between public and private sector, and analyze its role in developing Smart City. The study also proposes various ways to facilitate such development in each of critical categories. For this purpose, this research studied 228 smart services across 11 categories registered in the Ministry of Land and Transport in Korea to analyze the spatial distribution of smart services by spatial hierarchy and their characteristics Also, the research conducted a case study of MetroGIS, which is an information collaboration governance system for the greater area of Minneapolis and St. Paul in the state of Minnesota, United States, to explore how governance is formed; its organizational structure; the role of sub-level organization hierarchy and their interrelationship. The results of the analysis suggest that the following conditions are required to create a smart city: first, public sector resource assistance for building community; second, enhanced communication system within the community and with outside the community; securing financial stability and establishing a model of sustainable development to induce the community to evolve into a governance form.

US Army Found Five Lessons For the Urban Operations After Implemented Offensive Operations in Mosul, Iraq for the First time in the 21st Century. Based on these lessons the US Army Adds Spur Preparing For Future Megacity Operations Such as Weapon System, Warfighting Concept, Structure and etc. Korean peninsula experiences rapid Urbanization, so the Megacities are also Expected to Increase by this trend. So the ROK army also need to Benchmark the US Counterpart, so that the Organization needs to prepare following Elements. First, Establishing Collective Intelligence Platform for uture Megacity ops. Second, force Builing Optimized for the Megacity Operations(Warfighting Concept, Weapon System, Structures), Lastly, Establishing Megacity Synthetic Training field. By Preparing so, ROKA can Assure its Success in Future Warfare.

Since the opening of Seoul Subway Line #1 in 1974, the number of passengers has been increasing. The possibility for passenger's accidents in railway stations has also increased. In order to decrease these kind of accidents, railway operation systems have been automated. Nevertheless, the possibility of a casualty accident in railway stations remains. This study analyzed the type of casualty accidents, casualty accidents by age, sex, pedestrian facility, and passenger type based on the internal data of Seoul Metro. The causes of casualty accidents are also found out. Finally, the establishment of railway safety education program and railway safety experience center are suggested in order to prevent the urban railway casualty accident in advance at railway stations.

This study attempts to create a longitudinal dataset by linking tdata on the identical individuals across the monthly sample household management lists of the Economically Active Population Survey(EAPS) and the Household Income and Expenditure Survey(HIES). Using the data constructed through such process, the study also tryies to analyze the duration of longitudinal responses and the characteristics of nonrespondents. Between 1998 and 2002, longitudinal response rates had declined to 46% of total EAPS and 34% of total HIES. The fact that nonresponse was not a random phenomenon leads to concerns about the representativeness of the remaining sample. Using Cox's proportional hazard model the study revealed that the duration of longitudinal responses is affected by the ownership of house and the age of the respondent.

The goal of this research is to identify the energy planning techniques of Smart Green City and to establish the realized plan through the analysis of Multi-functional Administrative City. For the research, eighteen planning techniques were derived and categorized into three sectors and six basic direction through literature review and Brain-storming analysis considering correlation between three goals of Smart Green City and expectation of planning technique. And Multi-functional Administrative City was analyzed for the current status of application of planning techniques focus on two application aspects. In conclusion, 'Establishing Integrated Management Center for Urban Energy', 'Building Energy Management System', 'Building Automation System', 'Green Transport System', 'Intelligent Transport System', 'Introduction of Eco-friendly Transportation' planning techniques in reduction of building energy consumption sector and green-intelligent transport system sector were identified as important techniques for Smart Green City.

As part of the Smart Seoul policy, the importance of using big urban data is being highlighted. Furthermore interest in the impact of transportation-related urban environmental factors such as PM10 and noise on citizen's quality of life is steadily increasing. This study established the integrated DB by matching IoT big data with transportation data, including traffic volume and speed in the microscopic Spatio-temporal scope. This data analyzed the impact of a spatial unit in the road-effect zone on environmental risk level. In addition, spatial units with similar characteristics of road traffic and environmental factors were clustered. The results of this study can provide the basis for systematically establishing environmental risk management of urban spatial units such as PM10 or PM2.5 hot-spot and noise hot-spot.

This study is aimed to present a direction of urban development around regional private university site through the case-study in Joongbu university. Regional private university is in the face of a difficult problem for expansion of campus because of increasing of students and a lot of non-planned development in the circumstance of university site. Therefore we need an planned-development for expansion of university campus. This study abstracted of a direction for development by analyzing the land-use behavior around Joongbu university site.

The systematic data management system in the area of river flow analysis has not yet constructed, even though the need is evident due to the complicated process of tremendous input/output data in the modeling study and the importance of visualization of spatial flow variation. The objectives of this study are to suggest the method for constructing the NGIS-based river database based on contour, river, elevation, boundary layers and river cross sections and to provide the algorithm for interpolating equi-distance river cross section points. The selected study area is the main Han River starting from Paldang dam site to Indogyo bridge. The constructed database will be useful for the scientific water flow management system in the study area.

최근 증가하고 있는 자연재해 중 지진의 피해는 전체의 재해에서 차지하는 비중은 상대적으로 적지만, 빈도와 강도가 증가하고 있으며, 대응하기 위한 예측 체계가 거의 없다는 것이 어려운 점이다. 일본의 후쿠오카 지진 이후 내진설계 기준이 강화되고 있으나 실제지진발생시 최대가속도의 크기와 전파속도에 대한 이론적인 연구는 있었지만 국가적 차원의 자료 구축은 거의 없었다. 2005년 이후 소방방재청에서 지진대책사업단이 구성된 이후, 각 기관에 산재된 GIS 자료를 수집하여, 지진반응에 맞는 자료로 가공하고 프로그램으로 구현하게 되었다. anyguide 라는 지리정보도시 시스템과 Java 어플리케이션으로 구성된 프로그램을 통하여 과거의 지진자료와 측정지점에 대한 정보를 구축하였으며, 실제 지진발생 시에 지자체에서 대응할 수 있는 경보시스템을 동시에 구축하였다. 2007년 2월에 발생한 평창 주변의 지진발생시 시스템이 작동하여 3초내에 실제 shake map과 20초 이내에 hazard map이 작성되었으며, 실제 인명과 가옥 파괴 비율을 검증할 수 있었다. 2007년 말부터 2차 피해예측 추이 부분이 추가되어 보다 종합적인 대응시스템이 될 것으로 예상된다.

As the city in Korea has been developed rapidly and quantitatively, land viewscape has been neglected and is being recognized as one of the important issue that we have to interest in now. But land viewscape scene has not yet constructed numerically and objectively, therefore the analysis of urban viewscape had been made inefficiently, nonsystmetically, inexactively. In this study, the quantitative analysis of urban viewscape by using digital photogrammetry and GIS was made. At the result of this study, it was showed that 3D analysis of urban viewscape using digital photogrammetry is numerical, quantitative and objective not intuitive, quantitative and subjective.
