The purpose of this paper is to analyze the implementation of the karst infrastructure systems for the u-cave. IT based u-cave represents spatial information derived fields, such as geographical distribution of the cave boundaries, physical configuration of the cave locations and formation characteristics of the karst history. These three aspects relate to karst infrastructure systems, cave monitoring center and spatial database implementation. In terms of the IT based u-cave infrastructure implementation systems, the u-cave depends on IT contents and spatial features. uIT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". Cave should contribute to u-cave construction through the spatial analyses methods including USN, RFID, LiDAR, ELD, and GIS technologies. For these methods various cave functions will guide to u-cave's distribution, location, and characteristics of karst. The infrastructure consists of landforms and speleothem facilities, underground related facilities, environmental protection systems, and cave planning. These six units of the cave infrastructures have spatial databases that consist of spatial configuration, such as 4-D in order to draw the spatial distribution of the limestone and lava caves. IT based u-cave system infrastructure implementation should deal with IT convergence to generate fusion affects.

전통적으로 지리정보시스템은 지형데이터와 속성데이터가 결합된 정적인 공간정보를 처리한다. 기존 지리정보시스템을 발전시켜, 시간에 따라 위치 및 기하데이터가 변화는 동적인 시공간데이터에 연구가 한동안 진행되어 왔다. 최근 들어 유비쿼터스 컴퓨팅 환경에 대한 관심이 집중되면서, 센싱 데이터와 같이 속성데이터가 동적으로 계속 변화는 데이터가 급증하고 있고, 센서노드의 위치가 고정 또는 이동함에 따라 공간정보와 결합하여 관리될 필요성이 급증하고 있다. 이에 본 논문에서는 USN기술와 GIS기술을 융합하여 GeoSensor 정보를 효과적으로 관리할 수 있는 u-GIS 융합데이터 처리 시스템을 제안하고자 한다.

Nowadays, the importance of safety monitoring for facilities is increasing. Therefore, the introduction of ubiquitous technology to replace the existing manually-operated methods is required. In this study, a web-based GIS system that provides monitoring information of bridges in real-time for the application of a bridge management system through the use of ubiquitous technology is constructed. Particular attention is given to the effective interconnection of bridge monitoring information and bridge management system and, through a ubiquitous environment, how to connect this with the UFID and the GIS-based bridge management system (BMS) operated by the Ministry of Construction and Transportation. In addition, data expression methods are also suggested that state the detailed locations and attributes of structures in bridge management by using GIS.

Recently, much research has been actively conducted for a new kind of network environment ubiquitous computing. This paper will define the smart-tag technology required by a ubiquitous environment. We will describe how to apply smart-tag-related Radio Frequency Identification(RFID) research for GIS in underground social infrastructure, a local-area wireless-communication technology. Application development is important that will be able to materialize a network environment. This research promotes various application developments, such reason currently it establishes the IT 839 from domestic. The geographic information system construction is a part of IT 839. The research which is various becomes accomplished for the ubiquitous of social base facility from domestic. Consequently, in this paper analyzes the geographic information system of existing, researches based RFID underground social infrastructure management system development. The Proposed method is complements the method of existing, and is efficient for underground social infrastructure. This system is new management system for underground social infrastructure, and provides safe administrator function using authentication of active RFID tag. It provides real processing and autonomy of administrator.

Specially, location information can say that is important information in this ubiquitous environment and solutions of new GIS system to utilize this are required. Examine method to improve web geography information service system because this paper uses XML and presented specific implementation result. Through internet. it planed various geography information that offer in form of service that do not receive restriction of heterogeneous system environment. Also, did thing that is easy when request service about geography information that user need and deliver fast by purpose. Supplement and to improve open-ended and XML of form normalized use and developed existent web geography information service. So that can use map service in web browser without setup of application program that buy expensive GIS software or offer in each company design and implement.

U-City has been promoted nation-wide by development of recent IT technology. This paper studied the concept of 3D-virtual city in order to realize the current Ubiquitous City(U-City) efficiently, and to manage all the RFID/USN monitoring data in the real U-City. 3D-Virtual City is the concept of the reproduction of real world U-City, for embodying Ubiquitous technology while using Digital map, satellite image, VRML(Virtual Reality Modeling Language). U&V-City is the four-dimensional future city that real-time wire/wireless communication network and 3D-web GIS shall be connected that massive database, intelligent service be perceived through employing EAI(External Authoring Interface) that provides HTML&JAVA, and interface for efficient removal/process of massive information/ service and also by employing GPS/LBS/Navigation in support of world-wide orientation concept, and RTLS(Real Time Location System).

Informatization today has been developed in a ubiquitous environment unifying real and virtual space from digital space. To reflect on this trend, the government has promoted the u-Korea Project, which is a national strategy based on ubiquitous technology. With this national informatization policy, 'The Creation of the Infrastructure for Realization of Ubiquitous Country' for establishing a ubiquitous world is presented in the 3rd National Geographic Information System (NGIS) Master Plan, which manages national spatial information. However, we have not yet discovered distinct change for ubiquitous environments and practical technologies. The purpose of the study is to explain the current status of Ubiquitous policies and National GIS policies as a representative national information strategies directed toward the ubiquitous society by comparing Korea and Japan, and then develops improved strategies for the future.

The existing facility management system is capable of managing two-dimensional and three-dimensional models that were driven from maps and registered documents. However, it is not capable to collect various fields data on a real time and operate the integrated systems. To supplement those obstacles, constructing a facility management system based on ubiquitous environment is needed. Therefore, this research has proposed the modified UFID(Unique Feature IDentifier), which is more suitable for the facility management by modifying management agency and serial codes system in the existing UFID. In addition, we established the procedures for ubiquitous environment based on facility management using proposed UFID. The feasibility of this research was assessed through case study focused on roadside trees. It is considered that the results can be applied to many other ubiquitous environments based on facility management.
