This study aims to provide improvement directions of related laws system to protect U-City infrastructure facilities. For this, the study analyzes oversea infrastructure protection systems and domestic U-City laws system. Then, this indicates problems considering U-City infrastructure protection through Industrial-University-Institute experts' survey. Based on this survey, this study proposes improvement guideline of laws system to protect U-City infrastructure facilities, including enactment the Guideline of U-City Infrastructure Protection, obligation of U-City Infrastructure Protection, revision method of related laws system for protecting intelligent facilities, and Management System of U-City Infrastructure Facilities.

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 purpose of this paper is to analyze the implementation of the GIS infrastructure systems for the u-City, GIS base u-City represents spatial information derived fields, such as geographical distribution of the urban boundaries, physical configuration of the urban locations and cultural characteristics of the urban history. These three aspects relate to urban infrastructure systems implementation, urban monitoring center implementation, and spatial database implementation. In terms of the GIS based u-Ci쇼 urban infrastructure implementation systems, the u-City depends on IT contents and spatial features. IT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". GIS should contribute to u-City construction through the spatial analyses methods. For these methods various GIS functions will guide to u-City's distribution, location, and characteristics of urbanization. The infrastructure consists of road and road facilities, underground facilities, related agencies facilities, dispatch systems, environmental systems, and urban planning. These six units of the urban infrastructures have spatial databases that consist of spatial configuration, such as dots, lines, and polygons in order to draw the spatial distribution of the u-City GIS based u-City urban infrastructure implementation systems should deal with It convergence to generate fusion affects.

This article describes power supply infrastructure construction methods which are considered from U-City infrastructure. For the eisting city and town, it is one the issue to find an economic method to construct outside infrastructure including ubiquitous service device. Because the economic construction method could minimize the construction budget which cost big portion of U-City. And the power supply infrastructure is the fundamental layer to keep network and service layer stable. This paper suggests several ways to construct methods with keeping pre-constructed underground power cable by attaching inepensive power nodal controller working in zigbee network and introduces how to monitor and mana ge the status of power supply to network and service device.

IT technologies applied in the urban places are being promoted in each area. Especially infrastructure is performed in the central role of technical support in urban area. However, u-City infrastructure has lack of integrated way and concentrated on only feasible technology which cause frequent substitution and the nested technology in urban area. Therefore this study sheds light on infrastructure through a overall considerations of urban compositional elements and interactions, and apply technology in the process of the industrial era, the domestic supply of urban infrastructure and the cycle comparison-analysis deal with the domestic implications when applied. The results of the study, first, the u-City infrastructure should be supplied by public. Second, u-City infrastructure is in need of the agile character, and standardization of the subtleties is needed. Third, a new system of integrated-macroscopic perspective should be established by changes that influenced by convergences of IT technologies and infrastructures. Fourth, u-City infrastructures planning should consider interactions of services, devices and systems.

The Korea built successfully e-Korea based on the best of internet infrastructure which was constructed in the world. Continually, Korea is constructing u-City for twenty-first century to enhance the quality of life and to grow up IT industrial. But there is no standard model for u-City because three main builders, central government, local autonomous entities, and communication carriers have respectively their objects, targets and domains. If u-City would be constructed by the common infrastructure for ubiquitous communication, it will be possible to provide any ubiquitous services and compatibility. And the communication infrastructure has to be reflected on the first stage of city planning to reduce high cost for u-City construction. This paper mentions firstly the ranges of communication infrastructure and shows how to construct it each range.

The u-City is next generation IT-City which is to enhance the quality of life and convenience of life base on merger up-to-date communication infrastructure with u-IT services. To realize u-City, intelligent building is built for citizens to make a space of comfortable life. The intelligent building is possible to be constructed by communication infrastructure for various U-services. This paper mentions the ranges of communication infrastructure and shows how to construct it each range through regulation, law and technical. Lastly, the topics are suggested to build successfully u-City constructions in Korea.

This article describes a LED illumination infrastructure for ubiquitous society based on the Visible Light Communication technology. The VLC is one of the advanced communication system using "Visible Light". The VLC system has a lot of advantageous features and can be used in various places for the next future generation. So, we analyzed ubiquitous service model based on the VLC system and some applications. And we renewed discussion about LED illumination infrastructure for u-Society.

u-City is a new concept and phenomena of applying Information & Communications Technology(ICT) into real cities in Korea. In order to effectively integrate a city with high-tech ICT infrastructure, cutting-edge ICT is being integrated into physical urban environments from the planning and construction stage of a city. There are positive expectations regarding its effect on urban planning and citizens' lives. However, construction of u-city has technical limitations as well as institutional obstacles. This paper aims at identifying problems of current u-city practices and suggesting appropriate solutions for those problems. To do so, it first collects opinions from diverse experts. Then, it draws problems and suggests solutions in terms of u-infrastructure, u-service, policy and implementation process.
