There is not enough knowledge on how to use, build, and apply ubiquitous technologies such as the ubiquitous sensor network, GIS, statistic analysis system, mobile GPS system etc. Also there are other questions such as, how should the knowledge information resources be managed and web decision making system developed for national park management. The purpose of this study is to propose a framework for the national park integrated management system based on ubiquitous information technology. This study will include followings: 1) this study explores what ubiquitous information technologies are needed for national park management, 2) this study proposes building strategies about the spatial and attribute database using ubiquitous information technologies, and links methods among geographic information system, analysis program, sensor network, etc. The results of this study will contribute towards deciding a direction for national park policy in preparation for the ubiquitous computing oriented society.

위치 기반 서비스(LBS)는 유비쿼터스(Ubiquitous) 시대에 필요한 핵심 엔진으로 그 중요성이 논의되어 왔다. LBS 시스템은 GPS 뿐만 아니라 휴대폰을 통한 고속 인터넷 접속을 사용하여 사용자의 위치 추적과 같은 기술이 현재 서비스된다. 그러나 소프트웨어 측면에서 대부분의 위치 기반 서비스는 서비스 제공자 위주의 일부 특정 상황을 가정한 서비스 모델 또는 사전에 정의된 일정 지역과 한정된 상황에서의 상황 인식(Context Aware) 서비스 제공이 대부분이다. 그러나 이러한 방법론들은 현실 적용이 어려운 문제점이 제기되고 있다. 본 연구에서는, 사용자들의 상환인식을 통하여 사용자의 특성 지식과 공간지리 선호도 지식 정보 추론을 통한 Geo-Ontology통합시스템을 제시한다. 본 연구에서는 Geo-Ontology통합시스템 중에서 사용자의 상황인지기반 LBS시스템을 제시한다. 사용자들의 개인적인 특성 지식과 공간지리 선호도 지식을 구축할 수 있으며, 이러한 특성으로 구축된 지식 기반 하에 입력된 사용자 정보와 추론을 통하여 사용자의 현재 상황에 대한 가장 적절한 추천 결과가 도출되는 프로토타입 시스템을 제공 할 수 있음을 보였다.

This study was carried out to embody monitoring system of growing environments of fruit tree with Ubiquitous Sensor Network and to analyze various fruit qualities by the tree's vigor in the apple orchard located in Poonggi-eup, Yeongju-shi, Gyeongsangbukdo, Korea. The tree's vigor of apple trees was influenced to insolation, temperature, and humidity and it had influence on the weights, sugar contents and the quality(especially in mineral contents) of apples. The use of Ubiquitous Sensor Network will not only contribute to improve the quality of fruit by the offer of scientific fruit-cultivation method, but also to expand its application more and more.

Korea's GIS market has been proliferating since the 1990s, but still its scale and the structure require overall rearrangements. Recently as the needs and initiatives from central and local governments go stronger to drive 'u-City(ubiquitous City)' developments, there are much more demand of spatial information from sectors like city management, construction, environment and so on. Through the merge between GIS and the advanced Information and Telecommunication Technology, the introduction of new Ubiquitous IT is swiftly changing GIS market environments, so the GIS industry is to be prepared for this trend. The pioneering developments of Ubiquitous-related GIS technologies are expected to highly boost spatial data and related industries, and the pre-occupancy of those technologies in the world would enable the expansion of overseas export market. In the context of these epoch-making chances, by looking into the actual status of GIS industry, this study is to investigate the actual accomplishments to foster the GIS industry through Korea's National GIS Master Plan. Thereby, impending issues will be discussed to provide useful problem-solving suggestions.

Recently, the development of the information-communications industry has created a new paradigm of the ubiquitous and the smart environments. An USN is a typical technology for constructing a ubiquitous environments. But the USN technologies applied in practice have a lot of problems and to solve these problems that this study was to build a test bed. For the creation of the needs of USN technology, we suggest a method and service of monitoring of road hazards combining the USN and the Geographic Information System(GIS). We conduct making the USN equipment relevant provisions surveys, making installation guidelines, construction system and real-time testing. This study is capable of the management of public facilities, real-time monitoring of accident and the environment data and is expected to be expanded to a 3D facility management combineded with BIM in the future.

The purpose of this study is to analyze DMB(digital multimedia broadcasting) technologies of transmitting GIS-based traffic information for developing DMB systems compared with FM DARC(FM data radio channel). R&D and standardizations for transmitting GIS-based traffic information have been rapidly changed, as radical developments in ITS(intelligent transportation systems), telemaics, and communication methods such as ubiquitous and convergences of broadcasting and communications. Each communication method employs different GIS format, protocol, and standardizations, i.e., GML(geography markup language) and TPEG(transport protocol experts group). This paper presents technical methods and trends of transmitting traffic information using broadcasting along with FM DARC, in general, and DMB, in particular.

Ubiquitous has been a new issue in information technology field. Some people in GIS(Geographic Information Systems) and urban and regional planning have maintained that not only building three dimensional graphic environment in cyberspace is the key for ubiquitous, but also planners should plan and control the new space. They may believe that ubiquitous would be a mixture or/and combination of real-space and cyberspace. For strengthening their arguments, they should show the character of the space can be related to the three dimensional space and planning the space is possible. This study tried to critically analyze their assertion. After reviewing various articles and studies in multidisciplinary view, this challenging analysis shows those arguments need more sophisticated studies and can limit the character of cyberspace which has made the space prosperous.

Many of the wells which were constructed to use ground water resource are abandoned and not managed efficiently after its use. And a variety of heavy metals and organic compounds are released from the abandoned wells and this can cause ground water pollution. Therefore in this paper implemented to monitor locational information drill holes and underground water sensing information on real time basis using u-GIS environment to combined ubiquitous sensor node and GIS technology to improve these problems. In addition, this system suggests using system by UML 2.0 by analyzing variety requirement of user and between system internal modules interaction and data flow. It provides graphical user interfaces (GUI) to system users to monitor water-well related property information and its managements for each water-well at remote site by variety platform by GIS map and web environment and mobile device based on smart phone.

It defined the standard list of the urban foundation facility which from the local self-government it is managing with commonness and standard items and standard option and a construction plan it drew up "Urban Foundation Facility Electronic Library" it researched. "Urban Foundation Facility Electronic Library" defines with the aggregate of the component DB which lets to collect the organization, quality and form of the urban Foundation facility back attribute item system from the Geographic Information System(GIS). Consequently after the "Urban Foundation Facility Electronic Library" is constructed, it presented the application plan from on-the-spot inspection. Also it applied in the ubiquitous environment which is actualized quickly the plan which it does in the RFID and sensor network and electronic library grafting it presented. The connection use of the RFID and was possible from the Facility civil official test which applies the RFID.
