U-Services, which are offered from local governments based on their Ubiquitous City Plans, are only focused on facility and urban management services. Also Citizen oriented U-service is only planned. This study's purpose is to propose the implication for provide of the Citizen oriented U-service comparing with U-Service plan of 'Ubiquitous City Comprehensive Plan' and 'Ubiquitous City Plan' through a network text analysis and word frequency analysis. It was calculated a important keyword that was extracted the service plan contents of the 'Ubiquitous City Comprehensive Plan' and 'Ubiquitous City Plan' of the four local governments. The network text analysis and keyword frequency analysis was performed through derived keyword. Based on the analysis results, awareness of the citizens can be expected to increase about U-City by activating a excavation of Citizen oriented U-service in a variety of sector through additional services and policy of financial support in the next Ubiquitous City Comprehensive Plan.

Last February, $\ulcorner$The Act on Ubiquitous City Construction and etc.$\lrcorner$ was approved by the National Assembly. The law stipulates the regulations on the planning, construction and management of the Ubiquitous City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet ubiquitous city requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new planning approaches to realize the u-City in reality. It is also to supply with the framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the purpose of the establishment of comprehensive planning system, the theoretical bases were sought in relation to planning u-City, pre-existing u-City development cases and regarding regulations were analyzed, and then basic concepts, features, and constituent factors were set up.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. The ultimate goal of the u-City construction is the advancement of national territory utilization and management using Korea's high level of IT and spatial information infrastructure. Based on the definition of the u-City Construction Law, the u-City refers to a city where u-City services are provided through the u-City infrastructure applying u-City technology. But, based on the current level of relationship model among u-City service, technology and infrastructure, it is not enough to guide the local municipalities to plan and provide the successful u-City services in its vicinity. So as one of the core issues for the legal arrangements of successful u-City services, the purpose of the study is to suggest the basic directions and execution strategies for the relationship establishment among u-City service, technology and infrastructure.

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.

Recently, developing U-City as an integrated set of ubiquitous space services has been regarded as a promising field in realizing ubiquitous computing technology. However, well organized requirement analyses of U-City to declare what kinds of ubiquitous space services are needed and which ubiquitous computing technology should be incorporated to come up with the needs are still insufficient. Hence, the aims of this paper are to propose a set of unique U-City construction philosophies and to analyze which services should be offered in the ubiquitous space services in U-Cities. A field survey to the citizens who are potential end users of the ubiquitous space services was conducted to analyze the success factors of U-City using CSF methodology. Focused group interview with professionals in the field of ubiquitous computing technology in Korea was then performed to identify the relationship of the ubiquitous space services and the critical success factors.

In this paper, the requirements for information security are presented in the ubiquitous ecological(u-Eco) city. The various definition of ubiquitous city is analyzed first, the concept of the u-Eco City, services and major projects are then presented. The framework of the integrated operating center for u-Eco city is proposed, the privacy, data security and network facility protection in the center are analyzed. Unlike to previously proposed security algorithms, the light-weight encoding algorithms(such as block/stream encoding, pseudo-random generator, hash function, and public key encoding) in the u-Eco city center are required to communicate the information in the ubiquitous sensor network. Furthermore, the principal policies guaranteeing the secrecy and authentication for the private information are also presented.

This paper presents the main business models in ubiquitous city (u-City), the future city strategically integrated with the ubiquitous computing technology. Based on the concept of u-City, the chief services related to the u-City that has been actively developed are analysed, and then the best main four business models (u-Tour, u-ITS, u-SCM and B2B) for SongTan city are presented. The four business models are selected from making an analysis for the present situation of the tour industries, industrial complex, traditional market in SongTan. With the business models, the strategies to realize the active business transactions, high revenues, high value-adding industries, self-sufficient business through the construction of u-City are also presented. Finally, the promoting plans for local autonomy party, citizen party and consortium of industries/universities/researches to give an comfortable u-Life to citizen in SongTan are described.

Recently, developing U-City as an integrated set of ubiquitous spaces has been regarded as a promising field in realizing ubiquitous computing technology.

This paper intended to observe the present state of the U-City development in local governments and to present the basic view-point to carry out it in the context of total urban area. Also, this paper has a meaning to present a fundamental perspective for making plan to go on the U-City development. For this reason, it was investigated on the concept of 'Ubiquitous', the related technologies to realize the U-City, the related policies for 'Ubiquitous' in the central government, and the circumstances of the U-City development in the local government. Finally, on developing the U-City in local government, this paper presented its developing direction in the context of the whole urban structure and in the relation with the developed urban areas.

Recently, the concern of ubiquitous City(u-City) in each level of governments is on the increase, and they are professing themselves to follow the u-city concept on constructing new urban development or urban renewal project. But the u-city plan and construction proceed as the simple sets of advanced technology without fundamental space concept or space plan of the u-city. Therefore, the u-city as a citizen's living space and a basic urban environment is defined in this article, the viewpoint of the space plan and the recent trends of u-city in korea are reviewed. On the basis of this review, this article proposed an approach of the spatial plan for a u-city construction, here the approach consisted of the 3 stages of planning, constructing, and maintaining of the u-city, and finally the role of the participant in the each stage and spatial hierarchy was proposed.
