The goal of U-Eco City testbed is im proving the technical com pletion of ubiquitous technology /services which have been developed in other core projects in U-Eco City, by implementing newly developed ubiquitous technology/services to testbed. When the newly developed ubiquitous technology/services are implemented in the testbed, we will monitor whether the developed ubiquitous technology/services can be applied in the real situation and if they have problems we will find out the solution to solve the problems. In addition to this we have goal to sale experience of construction of U-Eco city testbed to the local governments and foreign cities. To accomplish this goal, it is necessary to make the guideline for the construction of U-Eco City. Final goal of this research is develop guideline for the construction of U-Eco City. I developed the framework of U-Eco City construction guideline by i) analyzing problems when the local governments try to construct U-City, ii) finding out general idea of Eco City and investigate connection between Eco City and U-City, iii) analyzing main steps of constructing U-City, and iv) matching the all the issues and considerations into process of u-Eco city construction steps.

The development of the Information Technology(IT) has brought enormous change to the human life, not even only to the politics, economy, society, and cultures, but all the way through the people's consciousness and cultural patterns. However, the information society resulted information inequality issues and especially to those disabled people, who have more difficulties on the technology adaptation, the "digital divide" symptom is significantly found. At present the rapid development of IT has gone beyond the level of the information society and it is accelerating the ubiquitous society that will combine people, computers, and all objects into one. And during the time of ubiquitous the "digital divide" will still exist. This research is focused on the digital divide of disabled people that were insufficiently covered in the research of digital divide and ubiquitous. From the empirical study of the effect that the disabled contributes on the service usability in U-City, the factors of background of the digital divide, and the difference of such factors in types of sex, ages, disabled types, and disabled class, and finally how the ubiquitous divide of the disabled affects have been researched. Based on the proposed study model and by analyzing the model by structural equation, following resulted was gained. (1) With the TAM (TAM : Technology Acceptance Model), which is commonly used in the studies of IT devices and services, the digital divide of the disabled cases cannot be identified sufficiently since it is not eligible for Using Intention of U-City Services. (2) In case of the disabled, the mental factors like willingness to overcome the impediment and accessibility like environment to meet the information services and ability to access the services are more effective on Using Intention of U-City Services rather than TAM.

A Ubiquitous City (U-city, Smart City) is one that ties information communications technologies (ICT) into many facets of city construction, thereby implicitly intending to function as a smart city that aims to be efficiently managed as well as provide an enhanced standard of living for its residents. Laws related to the construction of such ubiquitous cities point to integrated city management centers, intelligent facilities, and U-City infrastructure, among others, as central components of U-Cities, but do not provide a standard for these structures. Consequently, building of U-Cities by local governments are based on arbitrary judgments constrained the myriad of practical limitations that they face. Such ambiguity brings to light the need to find ways to improve the quality of these efforts. The first and second stages of this research examine the status of the components of a U-City -ubiquitous planning, technology, infrastructure, and services - and undertakes a comprehensive review thereof, with evaluation criteria formulated on the characteristics of stability, connectivity, goal-orientation, and development potential. In the research's third stage, a realistic and detailed evaluation index by which U-Cities can be renewed, demonstrated, and applied (???) is introduced in a step-by-step fashion, which will allow for local governments to properly assess the standard of their U-City in relation to the realities of the locality. Through the research result, it is expected that the index will become a part of the continued development and advancement of the "smart" character of an autonomous U-City at the local scale, and contribute to the overall revitalization of the U-City.

"The Act on Ubiquitous City Construction and etc." stipulates the regulations on the planning, construction and management of the u-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 u-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 IT infrastructure construction process of the u-City in reality. It is also to supply with the each step framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the u-City IT infra construction guide line v1.0, purpose of the establishment of comprehensive IT infrastructure construction process.

The ultimate purpose of cities is 'the enhancement of quality of life in city'. In order to achieve this, it is required to optimize the Ontology-driven ubiquitous services included in the U-City and UIS of regions and communities and so on. Almost U-Service's contents are related to spatial or temporal extent. So it is important to design Spatio-temporal event schema for efficient access to U-City. There is a rapid change into an urban society in the shape of Ontology-driven ubiquitous services in which a content on a region or an incident is newly reconstructed through various ideas with the influence of the ubiquitous environment.

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. Among u-City elements, the u-City Management Center has its own meaning and importance in roles which are crucial to the u-City developments, and its legal establishment is one of the core u-City realization factors. The purpose of this study is to analyse its overall problem issues regarding the function and location of u-City Management Center and then to suggest the basic direction and enforcement strategies to form its legal basis. As a result, in order to enhance the possibility of successful realization of u-City Management Center, the classification and standardization of function type, allocation of detailed functions based on u-City project hierarchy, and practical definition and relationships among basic u-City components such as u-City Service and Infrastructure were suggested. Also, practical execution devices on revenue sources and private sector participation, as well as the legal basis stipulating the mandatory inclusion of u-City Management Center development for u-City projects, were suggested.
