The Purpose of this study is to provide an effective way of developing GIS to UIS at the local level. For this purpose, the study typologically reviews the developing processes of UIS and utilizes a case study as research method. As the case, the study selects three types of UIS such as FM based UIS(Kwacheon), Urban Planning based UIS(Cheungju), and LIS based UIS(Taegu Nam-Gu). Based on these three UISs, the study concludes as follows. First, the developing process of GIS to UIS began with isolated approach through integrated model and finally to internet UIS. Second, UISs follows similar processes to that of GIS construction. Third, local governments focus on the development of FM based UIS of which construction budget is financed by the central government. Based on these findings, the study provides policy alternatives for the successful construction of UIS.

From the perspective of client-oriented administration, the study introduces the basic structure of Urban Inormation System (UIS) and examines problems and new strategies of UIS in Korean local governments. The study selects five metropolitan cities for a case study. According to this case study, UIS in Korea are focused on AM/FM and internally used only by practitioners. No government surveyed what their citizens want to get from UIS. To solve these problems, the study proposes developing strategies for client-oriented UIS as follows. First, local governments could use policy delphi technique to sum up the citizens' needs on UIS. Second, they need to pay more attention to the diversity and transmutability of administration zone and consider the importance of the connection between administration zone and attribute data collected on them. Third, UIS needs to keep a balance between AM/FM and living GIS. Fourth, internet UIS needs to be constructed which enables citizens' access to UIS more easily. Finally, GIS education and client-oriented administrative education need to be combined to improve government employees' mind for UIS.

It is essential to build a high quality database in developing a UIS to enhance the administrative effectiveness of municipal governments. To secure such a high quality DB, a proper methodology of quality control should be established. It is imperative to have such a method fit UIS DB considering that the conventional method has mainly been focusing on the quality control of the digital layers itself. Therefore, this study have analyzed the city of Inchon's UIS DB to devise a proper method to categorize the types of errors and to identify major relevant items. Also, the magnitude and frequency of each error along with its major cause have been analyzed to propose a quality control procedure to minimize the errors

Some local governments in Korea are currently developing various Urban Information Systems (UIS) to computerize their work. But they have spent too much money on their own UIS development because they have not reused the existing UIS of others. It has caused the central government to invest money repeatedly. The work of some local governments is generally very similar to those of others. The purpose of this paper is to suggest a solution to the reinvestment problem. To solve the problem, this paper suggests that they could model a city's business using Unified Modeling Language and Component-Based Development Process (CBD). They could also develop a UIS from the existing models, and then other municipalities can reuse the developed UIS. This paper illustrates the water supply business of P City in Korea and Rational Unified Process as a CBD. This paper also describes methods to apply CBD, to establish a reusable business model, analysis model, and design model, and to develop the software components of ActiveX Controls form for the water supply business.

The structure and dimensionality of the User Information Satisfaction (UIS) construct is an important theoretical issue that received considerable attentions. The acceptance of UIS as a standardized instrument requires confirmation that it explains and measures the user information satisfaction construct and its component. Based on a simple of 670 respondents who participated in dealing with the Public Management Information System (PMIS), this research used a confirmatory factor analysis to test the alternavtive models of underlying factor structure and assessed the reliability and validity of these factors and items in the PMIS. The result provided a support for a revised UIS model with four first-order factors and one PMIS The result provided a support for a revised UIS model with four first-order factors and one second-order (higher-order) factor in PMIS. To cross-validata these results, the author reexamined two prior data sets. The results showed that the revised model provides better model-data fit in all three data sets.

Recently, urban information system(UIS) has been developed and utilized by local governments in Korea and has become a key means of urban informatization of local governments. When UIS is conducted only for FM oriented internal utilization regardless of its cost-efficiency, however, its cost-benefit structure could be distorted seriously. The study utilizes benefit cost analysis technique and applied the technique to a model case of Chungju UIS selected by National GIS team. Chungju City developed its GIS for the management of roads and urban planning in 1993. At its beginning, the system was an efficient model with relatively strong cost-benefit structure and could produce positive net benefit 10 years' after its construction. When the city began to develop its facility management with the financial assistance from central government in 1998, however, its cost-benefit structure became distorted. As a result, it is delayed for the UIS to produce positive net benefit until the year of 2015. Using benefit cost ratio, discount rate and Mobile GIS, the study also conducts a sensitivity analysis.

For the development of automobile lighting components, various designers, developers and manufacturing personnel are involved, each group needing different software tools. In this Smartlite project, several software tools were developed far product development of the lighting components and then tested using two different user interfaces (UIs); the first was based on a commercial CAD system (SDRCI-DEAS) and the second was based on a web browser. The specific focus of this study was a comparison between the new web-based UIs, and the UIs on commercial CAD systems. The usability data have been collected from the users at Visteon and showed that the web-based UIs provided comparable functionality with the CAD-based UIs in terms of performance and usefulness. For the criteria of accessibility, the web-based tools out-performed the CAD-based tools.

With the rapid development of information and telecommunication technologies, the adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cuttingedge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

With the use of world geodetic system, the UIS DB of WonJu City, which was established on Korea coordinate system becomes to face the need of coordinates transformation. However, the UIS DB of Wonju City is based on dualistic control points of Korea geodetic system, which means the coordinates system is not standardized. Therefore it is required to establish a plan for transformation into world geodetic system. For this purpose, we calculated coordinate transformation coefficients per control point data of Korea geodetic system and verified the accuracy of transformation coefficients. Through the process, we propose a plan for transforming the coordinate system of UIS DB in WonJu City, which has been based on dualistic control point data of Korea geodetic system, efficiently into the world geodetic system.
