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.

In this paper, we have studied about the ubiquitous service map for the effective u-City service providing. Through the research, we are going to propose the fact that it can be implemented ubiquitous services according to city characteristics. The proposed research could make it possible to be an intelligent decision making system by city characteristics. Also, nation, local government, companies can be assigned their appropriate load according to the proposed system for the effective u-City services.

As the concept of Ubiquitous City has become an important issue, we need to have a voice in the field of privacy. The Ubiquitous Computing revolution, it is achieved a physical space and an intelligent union of cyber space in the space where an off-line space was integrated with on-line. It is combined with a life space naturally, and Ubiquitous creates a new integrated space. The space is the opportunity space that is limitless as soon as it is the unknown world that mankind was not able to experience yet. According to the recent papers and studies, Privacy or Personal Information sector is mentioned as a major problem for Ubiquitous Computing Society. Therefore, this paper checks Ubiquitous City, the present privacy concept and situation of currently proceeding Ubiquitous computing environment. Also, The main purpose of this paper is to analyze the concepts privacy, personal information. Thus this paper treated the analysis of case, technological or social issue, problem and solution, competing values of privacy and so on.

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.

A city development has been focused on solving a housing shortage of city resulted from rapid industrialization and population increase in city. However, such a development has caused many problems in environment, economy, safety, and so on. In recent, therefore, a new paradigm of a city development is required, and thus ubiquitous city (U-City) concept appears. U-City development, which combines construction method and IT technique, creates a new composite space, and help people improve quality of life in terms of solving many problems caused by existing method of a city development. However, there is no guide to build U-City up to date, and most present U-City projects have processed following past method of city development. Therefore, an objective of this paper is to suggest an explicit procedure of enforcement design in U-City system.

U-City related researches and development have been actively conducted in Korea since 2002. According to the Act on Ubiquitous City Construction, "U-City" is defined as "the city to provide ubiquitous service anytime anywhere through the existing ubiquitous backbone systems and ubiquitous technologies, ultimately for the purpose of improving urban competitiveness and quality of life. This research explains the plan to develop collective management technology for integrated operation of U-Space which makes up U-City. Specifically, this report is intended to suggest basic approach of identifying collective management elements of each U-Space type, developing integrated management system and creating interface module to link the system with urban integrated operation center.

A law and enforcement ordinance related to "ubiquitous city" (U-city) has been announced officially in Korea and practical standardization which is connected with U-city is in progress. The U-city defines citywide service over a city providing its infrastructure. The key facilities of U-city include intelligent equipments, networks, and operational facilities. Especially, the main focus of them is the intelligent equipments that are defined as facilities being applied to information technology. However, U-city has not been provided with standards related to actual construction of intelligent equipments so far. In this article, we survey standards for intelligent equipments for existing infrastructure and U-city's services.

The concept of ubiquitous is being applied on diverse industry fields as a new growth engine in Korea. With constructing u-City, new services which are called 'ubiquitous services' are developed actively. Even though there are active movement to develop u-service, there is no clear definition of what service can be defined as ubiquitous service. Given that this study proposes a u-service value classification framework focusing on services' characteristics. We conducted experts' group interviews to analyze new operating or developing services whether it can be ubiquitous. Study results show that some services are hard to be defined as u-service, so this study offers possible improvement alternative. The u-service value classification which offers clear definition of u-service can be used for the practitioners offering measurement framework of u-service level.

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.

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.
