Various studies have analyzed urban decline at a universal level using the general characteristics of declining cities. However, urban decline at the city level should be considered because this decay occurs based on the unique attributes of a particular city. In addition, since this phenomenon occurs and spreads in microspaces, studies should consider smaller spatial units continuously. This study aims to develop an urban decline measurement model that considers regional characteristics to analyze the urban decline of Ulsan Metropolitan City over time and space. The index value of Ulsan, compared to the national average, is calculated and reflected in the weight to reflect regional characteristics in the model. In addition, after analyzing urban decline by administrative dong units, we also performed analysis by counting district units using spatial hierarchical structure to demonstrate evaluation on smaller unit spaces. As a result of analyzing urban decline patterns by associating the index calculated using the model with the social phenomenon of Ulsan Metropolitan City, urban decline formed clusters and spread to adjacent regions over time. In addition, results confirmed that external factors such as new towns and urban regeneration projects affect urban decline. By illustrating the degree of urban decline proposed measurement model used in this study, it is possible to present the priority of areas required for urban regeneration projects. Results are also helpful to test the effectiveness of completed or presently-implemented urban regeneration projects.

As adopting ubiquitous technology into civil engineering, new city model is suggested called U-City. This paper proposes the framework of U-City management center to support effective services operation. The aims of the framework are to provide the development and operation environment for U-City services. Basically, these objectives are achieved by adopting the semantic web service technology to the framework. In this paper, OWL-S is mainly conducted to represent the description of U-City services. In addition, this paper insists that fine grained unit services are required to guarantee reusability, compatibility, and scalability of the services on U-City management center. The documentations conducted by OWL-S are provided as an example of service descriptions. At the last section, this paper also presents the architecture of U-City management center which enables automatic service discovery, selection, composition and interoperation.

With the rapid development of information and telecommunication technologies, the adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cuttingedge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

A city is the space which has a various historical experiment and memories. From these social and cultural environment, regional competitions through the introduction and settlement of a local self-government have been important in city marketing. For city development, a serial activation policies are come and in this process the native history and cultures have recognized as the core tool of cities. For possession of city competition, we have developed the cities' tangible and/or intangible cultural properties and make full use of a attractive asset. The city identity is established and the opportunity of a special space is made. This city identity has been dependent on spending time. We suggest the strategy for the historical and cultural city image through the historical element and the development of program for the promotion of publicity activities. The preservation and application of the modern architectures as the cultural and historical element promote the city image and build the position of city identity. We suggest the city marketing application strategy for the implication on the sustainable reproductive city.

This paper aims to draw essential facts of network city, to analyze the urban corridor in South-East region, Korea, as a network city. Firstly, the characteristics of the network city is examined theoretically. The global economy is developing an innovative class of network cities. A network cities evolve when two or more previously independent cities, potentially complementary in function, strive to cooperate and achieve significant scope economies aided by-fast and reliable transport and communications infrastructure. Network Cities place a higher priority on knowledge-based activities like research, education and the creative arts. Each constituting city stands to benefit from the synergies of interactive growth via reciprocity, knowledge exchange and unexpected creativity. Secondly, we discussed the network structure of cities in South-East region, Korea itself intensively. We survey the network location and outline of the urban corridor in South-East region, spatial specialization and interaction between the constituting cities. We also discussed the problems of the network cities in South-East region, Korea and introduced the desirable policies and alternatives. We can ascertain from the case study of cities in South-East region that the cities in South-East region corresponds the network city model fairly.

The purpose of this study is to explore the network city in detail as a new model for explaining urban growth in the changing economic environment in recent years. For this purpose, starting from Batten's (1995) pioneering work on network city in the mid 1990s to the most recent ones, literature is reviewed and various aspects of network city model are examined including formation process, spatial structure, application to management and urban planning, and growth potential. With this, the study aims at providing comprehensive knowledge necessary for evaluating if the network city model is appropriate in explaining the urban phenomena in the 21st century. The result of the review shows that network city model is the one appropriately explaining the changing urban system associated with the economic globalization and the development of transport and information technology. In addition, more and more European city governments tend to adopt this as the urban planning principle.

The pattern of urban transport activity has two major components: the movement of people and the movement of goods. Roads in urban areas carry large number of trucks laden with goods that support urban economy and lifestyle. Therefore urban goods movement plays a vital role, but at the same time, urban goods movement are an important source of congestion, and a major contributor to the adverse environmental and social impacts of urban transport. In addition, the demand for goods movement is growing at a faster rate than personal travel in many cities, due to changes in industry logistics and consumer purchasing patterns. As a result, the significance of urban freight activity is increasing in terms of both its role in urban economy and its adverse impacts on urban amenity. This study is focused on the role and involvement scope of metropolitan government in urban logistics aimed at increasing its efficiency and reducing its negative impacts. The major suggestions of this study are (a) development of a measure of urban goods movement activity, (b) evaluation of data requirements and availability, (c) dialogue between the public sector and private sector, and (d) the role of metropolitan government.

최근 발생되고 있는 도시지역에서의 침수피해는 과거와는 다른 양상으로 발생되고 있으며, 이로 인해 많은 재산피해와 소중한 인명피해가 발생되고 있다. 도시지역의 침수피해는 다양한 원인에 의해 피해가 발생된다. 기후변화로 인해 발생되는 높은 강우강도의 집중호우로부터 도시 피복의 불투수화나 부족한 우수유출저감시설로 인한 침투비율의 감소에 따른 유출량의 증대, 짧은 도달시간으로 인한 빠른 하천수위의 상승, 빠른 하천수위의 상승으로 인해 발생되는 하수도의 만관에 따른 관수로화로 인한 역류 발생, 역류된 홍수류의 도시 내 저지대로의 유입, 최대 조위와 맞물려 발생되는 홍수류 배제의 어려움 등은 도시침수라는 결과를 제공하는 주요 원인으로 작동하고 있다. 이러한 현실은 도시지역에서의 침수대책의 수립에 있어 과거와는 다른 특정한 대책의 수립이 필요하다는 점을 시사해 주고 있다. 특히 도시침수를 발생시키는 주요 원인에 대한 개별적인 대책수립보다는 도시침수의 발생확률이 높은 지역에 대해서는 이러한 원인을 종합적으로 고려하여 이를 방어할 수 있는 효율적이고 실제적인 계획을 수립할 필요가 있다. 우리나라는 현재 행정안전부의 자연재해저감종합계획, 환경부의 특정하천유역치수계획 및 하수도정비기본계획을 기본으로 소하천정비기본계획, 하천기본계획 등 소관 부처를 달리하는 다양한 계획들을 수립하여 홍수로부터 귀중한 자산을 보호하려는 노력을 시행하고 있다. 이러한 계획들은 주로 홍수에 대비하고자 하는 특정 구조물의 설계를 중심으로 하고 있으며, 설계에는 항상 경제성의 개념이 수반되므로 설계용량을 초과하는 자연재해의 발생에 대해서도 홍수 발생에 대비하기 위해서는 홍수예보 및 재난대응체계의 운용과 같은 비구조물적인 대책도 매우 중요하게 활용되어야 한다. 이와 같은 현실에서 도시지역의 침수피해를 방지하기 위해서는 이제 과거와는 달리 개별법에 의해 수립되는 각종 계획들을 특정공간에 대해서 종합적으로 고찰하고 최적화하여 현실적이고 효율적인 하나의 계획으로 수립될 필요가 있으며, 하천을 중심으로 시행되고 있는 홍수예보와 유사한 도시침수예보와 같은 비구조물적 대책의 기술적 제고와 시행의 확산이 매우 시급한 실정이다. 본 연구에서는 최근 발의된 「도시하천유역 침수피해방지대책법(안)」의 경과와 이 법률에서 다루고 있는 주요 내용들을 살펴봄으로써 향후 우리나라가 지향해야 할 도시지역의 침수피해에 어떻게 대응해나가야 하는지에 관해 살펴보았다.
