The U-City comprehensive plan has been settled on November in 2009 by U-City law which was enacted in 2008. On this, the U-City plan's framework which local governments established has been set. However, those who work for U-City in local governments and private sector would be fallen into confusion because they have not fully understood yet the concept of planning system in the U-City plan. In this condition of the early stage, some problems that are overlapping investments and lack of coordination between plans may occur. On this background, it is needed to understand the U-City plan's status and role by figuring out the relationship between U-City plan and other related plans. The goal of this paper is to suggest implications that are differences and similarities for coordination among the plans through a comparison with detailed instructions and laws related to U-City planning.

The GIS has grown in its quantity as local authorities established the urban information system for better city administration, civilian services and decision-making support services. Recently, local authorities have expressed much interest on the introduction of ubiquitous technology to improve citizens' safety and convenience. This has become the drive behind the construction of ubiquitous city(u-City). Construction of a u-City requires the multitude of information and telecommunication networks and digital contents; the existing information resources need to be put to use in entirety for that end. In that regard, the integration of GIS established and currently operated by local authorities needs to be strategically promoted. This study intends to propose GIS integration strategies in various aspects for the future u-City and directions for the development of urban information systems in the coming of the Ubiquitous Age.

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.

Up to the present point in time, the level diagnosis system for urban reactivation have utilized various methods for establishment and management in Korea and overseas, such as city competitiveness evaluation, urban decay diagnosis, etc. However, contrary to performing diagnosis and evaluations on general cities in existing studies, it is found to be a very complex and difficult task to perform a diagnosis on the level of U-City due to its unique characteristics. It is difficult to determine the level of a U-City using a level diagnosis system used for general cities because a U-City is comprised of a connection/fusion of various structural elements. Therefore, in order to perform a systematic diagnosis of a U-City, it is necessary to primarily observe the structural characteristics of a U-city to derive a diagnosis system based on the relativity between each structural element. This study aims to propose a directivity of a U-City level diagnosis system in comprehensive consideration of various elements, such as the objective of a U-City, as well as the structural elements that compose a U-City based on the definitions prescribed in U-City legislations, including ubiquitous city planning, ubiquitous city infrastructure, ubiquitous city technology, services, etc. The results of this study are expected to provide a resolution for the regional quality differences of U-Cities, and also establish a stepping-stone for the realization of U-Cities with high degree of completion.

The ubiquitous city construction act worked as an institutional basis for the U-City projects which were actively driven in the new urban areas until 2010. However, the country's urban policies which were recently changed focusing on revitalization of the existing towns and urban regeneration led to the increased demand for revision of the u-City law with a strong character of procedural law mainly for the new urban areas. Therefore, this study, taking into account the changes of the country's urban policies and the conditions related to u-City, established the direction of revision on the u-City law as the diversification of the u-City projects, reinforcement of u-City management operation and the supports for the u-City projects, and presented the consequent action plans. This study aims to review the problems with the current u-City law and the improvement plan from the practical point of view for reflecting the country's urban policy flow and demand. It is expected that the result of this study will be able to be utilized as a basic material for supporting the continuous development and expansion of u-City by law and system.

It is a fact that we are yet to recognize and sense the U-City even though the business of U-City construction has been started many years ago. One of the causes is that UCity was thoughtlessly developed in the industry-centered environment for a tangible achievement, despite of need on more systematic development and organized management. Fortunately, it is expected that the most part of the situation will be solved, since "laws on the construction of the ubiquitous city" for planning, construction and management has been promulgated on March, and U-City project will be systematically promoted by the related laws from now. Therefore, intention of this study is the sustainable development of the U-City by analyzing the previous process and problems of the U-City Construction project of local governments and reengineering U-City construction project process in accordance with new laws, using the BPR methodology.

Ubiquitous city which was appeared since 2006 is defined as "The city provided the ubiquitous city service anytime and anywhere using ubiquitous urban infrastructure to improve the city's competitiveness and quality of life" under ubiquitous city construction law. To realize the ubiquitous city, the city has to be constructed efficiently based on the spatial information. And connection of information achieve effective synergy. In this study, applied multilateral analysis to spatial information and administrative information to implement u-service focused on MACCA(Multifunctional Administrative City Construction Agency). Study about main function and product data with connection process of Korean Land Spatialization System and administrative information System was performed. Also, details of u-service and method of acquiring necessary data were derived. In Addition, the information connection possibility for efficient u-service realization was suggested by linkage analysis method to utilize the related information infrastructure jointly.
