It is important to manage the underground facilities efficiently because they are directly related to the convenience and safety of citizens. But the fact that the different agencies take on a role of managing the underground facilities respectively makes it impossible. So Korean government has exerted great efforts to solve this problem through several projects. Korean government expects that the ubiquitous technologies such as sensor and wireless communication in the domain of the underground facilities management will be useful. It is main duty of u-City Management Center to monitor several situations about the underground facilities using ubiquitous technologies. But there is no consensus about what concrete situations it has to monitor even though u-cities under construction. Because local governments or related companies are in charge of carrying out these roles yet, there is no legal basis on which to do these tasks by the center. And it is needed to develop new technologies for u-services efficiently. Because technologies for u-service are vast, various and converged, so it necessary to develop them according to priority or in cooperation with other developers. In this paper, we classify the monitoring items for each facility which were investigated by a recent research. It is expected to make use of defining the role of the center and developing technologies with u-service.

Since the 1970s, rapid Industrialization has brought urbanization nationwide. In this paper, thirty one years data(1973-2003) ate used to evaluate variability of major cities. Before assessing the context between urbanization and variability of rainfall, the rural areas are selected to compare with urban ones. Thus, average, trends, variations, and nonparametric frequency analysis methods were employed for evaluating variation of annual precipitation, seasonal precipitation, 1 hour annual maximum design rainfall and 24 hour annual maximum design rainfall for both urban and rural areas. The result have shown that summer precipitation relatively increased In urban areas compared to that in rural areas.

Recently, smart cities are attracting attention as a solution for a plethora of urban problems, including transportation, environment, safety, and energy. However, despite a substantial body of research dealt with the concept, trends, policy, and legal institutions of smart cities, few researchers have examined how the smart city services influence the cities from the dynamic perspective that considers the entire cycle of a city, including its growth, stagnation, and decline. Thus, it is vital to understand how the city changes with time from the view that a city is a system of sub-elements-population, industry, transportation, environment, housing, and land-closely interacting together. Within this context, this study explores how the urban dynamics of Anyang-city develop for the long term using the System Dynamics method and analyzes the effect of smart city project investment on the dynamics of Anyang-city. According to the result, Anyang-city is a "mature and stable" type, and its population is expected to decrease slowly by 2040. Specifically, the Anyang-city population will be reduced to 553,000 by 2030. It was analyzed that the number will decrease to 543,000 by 2040. It was also found that the investment in smart city projects in Anyang, based on the Plan for Anyang Smart City, would have the following effects: easing population decline, increasing number of businesses, improving urban safety index, and increasing average driving speed. The population will grow by 4,000 and the number of businesses will increase by 761 than before budget investment. The result of this paper is expected to contribute to identifying and predicting the effect of smart city policies from a long-term perspective.

Preliminary feasibility study on Busan metro line #1 in Yangsan line (Nopo-Bukjeong) depending on active volume of mass transportation between Yangsan city and Busan city was conducted. As the study concluded that it's valid, the necessity to establish the metro railroad network connecting to Busan, Ulsan and Gyeongnam Province is demanded to improve the transportation issues in Ungsang area vulnerable to metro service and to drive the balanced development between metropolitan cities. In addition, the volume of transportation depending on methods in target areas and road traffic assignment are surveyed to put a stress on the necessity to establish the metro railroad network. As the demand of transportation for alternative lines is predicted, the budget and benefits for construction for each alternative line set for the rough economic analysis depending on traffic volume for each method and traffic assignment results. The total project budget necessary for construction of proposal line #1 set as effective one among target three lines in this project is calculated in 794.32 billion won. Construction accounts for the most expensive in expenses for project and contingency allowances, purchases for vehicles and collateral expense are followed in orders. However, compensation for lands is not counted. In particular, according to economic analysis in proposal #1, ratio of benefit/cost (B/C) is 0.584, net present value (NPV) is -217.47 billion won, the internal rate of return (IRR) is analyzed in 0.604 %. At the current stage, it is not economically feasible, but the B/C is 0.737 in long-term upon construction of Yangsan line between Wolpheong and Yongdang which is proposal line #3. Therefore, when Busan metro basic plan is reorganized to aim the benefit of residents in Ungsang area vulnerable to the metro service, we think it must be necessary to establish the metro railroad network connecting to Busan-Yangsan-Ulsan which is proposal line #2 by extending the existing Sinjeong line and including this task line in high-ranked plan related to metro railroad.

자동차는 도시를 자연 전체에 흩어버려 놓는다. 아콜로지 하이퍼 빌딩에서는 인간척도를 중요하게 여긴다. 하이퍼 빌딩에서는 보행로로 움직인다. 하이퍼 빌딩 내에서 거리는 도보와 분으로 측정된다. 하이퍼 빌딩 안에서 자동차는 꼭 필요한 것이 아니다. 아콜로지에서 에너지는 일상적 현대 도시에서보다도 더욱 효율적으로 사용된다. 오염이란 비효율적인 사용이라기보다, 바로 낭비하고 있다는 뜻이다. 효율이 좋아지고 낭비가 줄어드는 것은 오염이 줄어든다는 것을 의미한다.

Bonjeong-tong(本町通) which was originated from Japanese place name and commercial center during Japanese colonial period speaks for downtown in the urban Korea of today. This study tries to investigate a variety of place memories that have been layered in Bonjeong-tong in the case of Chungmu-ro and Myeongdong area in Seoul, Korea. The author settles the concept of 'place memory' from the viewpoint of the discipline of human geography, and reconstructs place memories of Bonjeong-tong by three folds of layers focusing on the multilayeredness and the contestedness of place memories which have been piled up in Bonjeong-tong; 'the symbol of colonial power' vs. 'the emblem of modernization', 'the heart of monetary capitalism' vs. 'the ground of humanists and artists', 'the space of fashion' vs. 'the place of identity'. As a result, the author places emphasis on that a place like Bonjeong-tong in itself within a city is a sort of palimpsest, and suggests that therefore it is necessary to adopt a vertical approach not a horizontal one for the study on urban space in future.

The purpose of this study is to explore the possibility of the planning method of traditional market as the urban public open space and to attempt to create the essential reformation of traditional market place. The design concepts of the Moran traditional market project are establishing module system based on function of traditional market to accomplish the practical needs of vendor and consumer and expressing the liquid and autonomic characteristics of Moran traditional market to find the new and substantial schemes of public open space. The functional design module of the market place is based on 2.1m $\times$ 2.1m grid system which is minium market unit, and it is extended to 8.4m $\times$ 8.4m basic structural module and to 50.4m $\times$ 50.4m plaza unit.
