The paper reviews the relationship between mobile services and u-City services in order to promote u-City service. In the u-Cities, a variety of services are provided based on u-IT technology, which brings the benefits of efficient city management and offers convenience to the city residents. However, most of the available services are designed for the areas of city operation or administrative management, which hinders the growth and propagation of the services. Hence, the paper suggests a concept of mobile life service that is a service that can be ubiquitously accessible by city residents in everyday life. Accordingly, the paper examines and analyzes the usefulness of such services and the intention to use them by conducting a survey among the residents of the metropolitan area. The paper verifies that the mobile life service will contribute to promoting the use of u-City services.

KUbiquitous city(U-City) is a recent trend in urban planning and management across the globe. Currently, several typologies were developed and presented classifying U-City services, but validation research of these typologies are scarce. In this study, efforts were made to qualitatively validate the usability and practicality of a typology of u-city services. Using 228 U-City services identified in previous studies, classifying exercises were conducted against a typology. Three experts were involved in this expert heuristic exercise, against a most popularly used and comprehensive typology of U-City services. Findings indicates that the selected typology is high on comprehensive exhaustiveness, and empirical applicability while low on mutual exclusivity, simplicity and theoretical contribution. Implications for the typology improvement are suggested followed by limitations and directions for further research.

The purpose of this study is to define U-Eco City services and to analyze the possibility and easiness of application in urban space. The most significant meaning of this study is that these results could be used as the design and planning guidelines for integrated U-Eco City. This study progress as follows; First, U-Eco City concept and their services were defined and the spatial units of U-Eco City were distinguished through literature review. Second, U-Eco City spaces are classified into four levels such as building, street, facility and district. Finally, the application of U-Eco city services was analyzed together by the statistical technique of cross-tabulation. 35.7% of U-city services was serviced in urban district and 38.8% of Eco City services was applied to Building. U-City and/or Eco city services were adapted differently according to the urban spatial hierarchy. Those services should be applied in terms of the characteristics of urban space in designing and planning U-Eco City.

U-Services are inevitably essential for the realization of u-Cities. Most local governments in Korea have expressed much interest in introducing u-Cites and related u-Services. Since researchers anticipate that developing u-Cities will produce economic effects, the Korea government has support local governments to develop u-Cities and necessary u-Services. However, the technology issues have been dominiated in the field of U-City services and most of the U-City services do not reflects all the complicated and pluralistic sides of environment, which are caused by future uncertainties in developing u-Cites. For the purpose of addressing the above uncertainties, this paper attempts to develop the possible scenarios for U-City services through a scenario planning approach. A focus group interview and survey with professionals in the field of planning u-Cities was performed to identify these uncertainties. Then, in order to investigate the validity of the scenario planning methodology, the u-Service "u-Water purity monitoring" is adopted. After considering the relevant issues, we developed two possible scenarios: a mutual linkage service among u-Service related organization and a cooperating and coordinating service among local governments. On the basis of these scenarios, the strategies for potential U-City services are formulated. Various participants in developing U -City services are encouraged to use the scenarios as the foundation of predicting future features of u-Cities and developing the framework of the U-City service scenarios effectively.

A u-city is a vision of a city with computers and sensors built in to its infrastructure, and data sharing among the various information systems. A u-City provides several u-City services to the u-City clients. The u-City services for local governments contain two types of functions: common function and specified function. It is needed a study on generation of specified service models of local governments. The proposed service model divides functions of the city into two service areas: common support service and specified support service. And we suggest the way to generate the u-services of each local government in this paper.

U-City applies ubiquitous information technologies such as RFID, GPS, USN to various components of city functions and services. The concept of U-City was popularized especially in Korea and currently more than 40 projects have been carrying out all over country. U-City incorporates advanced information communication technologies into ubiquitous information services to provide better quality of life. The purpose of this study is to analyze preferences for the U-City services by surveying experts in U-City developing companies. This study employs Analytic Hierarchy Process which is very useful tool for performing multi-criteria decision making. Total of 28 responses were used in the analysis. The results indicated that the first 7 most preferred items were from transportation and safety area and environment and healthcare area and 4 out of 6 items in transportation and safety area were ranked among them. It implies that respondents consider countering anxiety caused by congested traffic, natural disasters, crimes, etc most important aspect that U-City should deal with. On the other hand, U-Port, U-Convention, U-Logistics, U-Public Administration and U-City Portal were listed as the least preferred services.

The concept of "ubiquitous" has become the top issue of the 21st century communications field within the past years. u-City has become the new city paradigm with the convergence of city planning and ubiquitous communication technologies and services. Starting from 2004, KT has collaborated with the Korean government to develop comfortable, convenient, pleasant, safe, and healthy IT technology based u-City focusing on; balanced development, value creation, and improved standard of living within the region. Presently the term, "hazard mitigation services" lacks a clear definition due to its varying applications by different local agencies and has caused confusion. Therefore, this report will clarify and define u-City hazard mitigation services currently proposed to the local agencies as well as services currently in effect. Additionally, the report will introduce hazard mitigation service models feasible by KT.

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.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.
