기존의 방대한 무선 인프라와 최근 이동 단말기의 발달로 무선통신 기술을 이용한 서비스 이용이 잦아졌으며, 이를 관리하기 위해 기존의 모니터링 시스템들은 표준화되지 않은 지리 정보 속성을 바탕으로 단일 이동 단말기에서만 적용 되었다. 따라서 표준화된 GIS(Geographic Information System)에서 이동하는 여러 개의 무선 시스템을 효율적으로 관리하며 제어 할 수 있는 시스템이 필요하게 되었다. 본 논문은 WIPI(Wireless Internet Platform for Interoperability)에서 제공되는 GML(Geography Markup Language) 위치 정보 시스템을 서버에서 통합 추적 할 수 있는 모니터링 시스템을 설계한다. 또한 이 시스템은 OGC(Open GIS Consortium)에서 제안한 GML 3.1을 기반으로, 여러 WIPI 사용자들의 공간 정보를 획득 및 저장하여 이를 추적 관리 할 수 있다.

This paper deals with the village names in Geoje City[Geoje Island], Hundreds of village names in the city are found to be based on some environmental features such as landforms, weather, and soil of the island. A considerable number of village names in the city are derived from the mountainous landforms with steep slopes or from the extremely indented coastlines with many small islands, and some village names are originated from the weather and soil. In this paper, it is realized that the village names often reflect the environments perception of the residents and that they can give some clues to the environment's changes of the places.

Public policy responses to the digital/information revolution and the micro-economic reforms that it facilitates have inspired exploration of the scope for local government implementation of digital spatial data handling(DSDH) of information relating to, among other things, asset inventory, environmental and utility management, address management, and planning. The results from these explorations are such that few doubt the value of bringing the public policies to practice, but diffusion rate and pattern of the approaches demonstrated by the scoping experiments will reflect institutional/cultural matters, indicators of the relative significance of which might be at least partly predicted from appraisal of case studies. This argument is exemplified by reference to case studies in adoption of DSDH by local government organizations in Korea and in Australia.

Distinguishing debris-covered glaciers from debris-free glaciers is difficult when using only optical remote sensing images to extract glacier boundaries.According to the features that the surface temperature of debris-covered glacier is lower than surrounding objects, and higher than clean glaciers, glacial changes in the Yigong Zangbo basin was analyzed on the basis of visible, near-infrared and thermal-infrared band images of Landsat TM and OLI/TIRS in the support of ancillary digital elevation model (DEM). The results indicated that glacier area gradually declined from $928.76km^2$ in 1990 to $918.46km^2$ in 2000 and $901.51km^2$ in 2015. However, debris-covered glacier area showed a slight increase from $63.39km^2$ in 1990 to $66.24km^2$ in 2000 and $71.16km^2$ in 2015. During 25 years, the glacier length became shorter continuously with terminus elevation rising up. The area of moraine lakes in 1990 was $1.43km^2$, which increased to $1.98km^2$ in 2000 and $3.41km^2$ in 2015. In other words, the total area of the moraine lakes in 2015 is 2.38 times of that in 1990. This increase in moraine lake area could be the result of accelerated glacier melt and retreat, which is consistent with the significant warming trend in recent decades in the basin.

The purpose of this study is to search GIS education in High School in Korea. Firstly, Expanded Content of GIS in the 7th National Curriculum call upon increased demand of GIS education. Secondly, It is urgent to development of GIS Education Program, There is insufficient practical instruction of GIS in High School because of ill-equipped environment. For that reason we proposed GIS program. Thirdly, It is necessary to integrate between 'Instruction about GIS' and 'GIS Assisted Instruction' in School. Finally, It is necessary to systematically prepare and study of GIS Education for the future National Curriculum.

This study aims to review what geographers have contributed to GIS industries and national needs. To-be-geographers and geographers are expected to meet the gap between what we have teamed in school and what we have to do after graduation. The characteristics of GIS industry in the 1990 are summarized with approximate evaluation of the contribution of geographers in each stage. Author introduced the requirement for the licenses of geomatics and geospatial engineering experts and the other licenses, which are important to get a job in GIS industry from 2003 to 2004. A set of questionnaire on the user's requirements was given to GIS people in private companies and public GIS research centers and analyzed. Author found that they put an emphasis on hands-on experiences and programming skills. no advantages or geography such as capability or integration and inter-disciplinary collaboration were not appreciated. The prospects for the GIS tend to be positive but the reflectance of the prospect was not accompanied by at the same degree of preference for geography. Most government strategies for the next ten years' GIS focus on new-growth leading industries. SWOT(strength, weakness, opportunity, threat) analysis of geography for GIS industry will give some directions such as telematics, regional marketing strategies with web-based GIS technology, location based service. That means intra-disciplinary study in geography will evoke the potentiality of GIS, compared with interdisciplinary studies.

There is a considerable community between Eight Constitution Medicine and disease ecology in that they examine the relationship between humans and environment in terms of genetic, environmental and cultural factors, in addition to the factor of germs. In this respect, the purpose of this research aims to investigate the community between Eight Constitution Medicine, a branch of Eastern Medicine and disease ecology in geography. The research method is to analyse the clinical results from 647 patients and the data from a field survey on the Yeonggwang-gun County, Jeollanam-do Province. The results are summarized as the following: First, geographical distribution of patients varies depending on the type of physical constitution; it is also divided into two types, an oceanic type and an inland type. Second, it is highly probable that there is a significant relation between a vulnerable disease in association with a type of physical constitution and patient's native place; there are diseases that are not associated with all the patients who have the same constitution; they might be incurred by the eating or life habits in association with the characteristics of geographical environment. Third, the case study of Yeonggwang-gun County, Jeollanam-do Province, with a focus on the mutual relationship among the three factors. shows that patients, who share in common the eating or life habits that coincide with their own personal types of constitution, maintain a good health condition; if not, they tend to be exposed to a various kinds of disease. Because the study on the community between Eight Constitution Medicine and disease ecology is now at the early stage, diverse types of approaches should be tried to be applied in the future.

일반적으로 지리정보 서비스의 목적은 사용자에게 어떻게 하면 좀 더 쉽고 정확하며 빠르게 정보를 전달하는가에 있다. 지리정보 서비스가 발달하고 정보통신이 발달함에 따라 많은 사용자 요구가 증가하고 있는데 그 중 전자 지도 서비스에 대한 요구가 증가하고 있는 추세이다. 기존의 지리정보 시스템(GIS)은 많은 웹과 연동하여 웹 사이트에서 지도 정보 및 주변위치정보(POI : Point Of Interest) 서비스를 제공하고 있다. 또한 지리정보 데이터는 그 특수성에 의해 정보의 현재성, 다양성, 위치정확도, 등급분류, 기타 주요 속성정보로 구성 요소를 정의 하여 제공하고 있다. 이에 OGC(Open GIS Consortium) 에서 제안한 지리 데이터 공유 및 저장의 표준인 GML(Geography Markup Language) 명세에 기반하여 POI 정보를 가시화하는 시스템인 GVP(GML Viewer POI) 설계한다. 특히 데이터 전송 트래픽을 최소화하기 위한 특정한 핵심 POI 위치 정보를 제공한다.

Since open-cut mining excavates gradually from the top of the mountain, vegetation planting is needed to reduce negative environmental impact on the surrounding environment. Accordingly, this study aimed at performing the environmental monitoring of the open-cut mining ground using the satellite remote sensing technique. As the research technique, in order to grasp the environmental change around the open-cut mining ground, NDVI (normalized difference vegetation index) was calculated, and every year change of the vegetation activity was analyzed. The results of the study showed lower vegetation activity in the open-cut mining ground compared to the surrounding areas and suggested the need for closed monitoring by remote sensing techniques.

무선 센서 네트워크는 컴퓨팅 용량 및 전력 자원이 매우 제약적인 특징을 가지고 있으며, 이로 인하여 동작시 실패하려는 경향(Error-prone)을 지닌다. 이를 해결하기 위하여 센서 네트워크에 적용 가능한 결함 허용 기법이 요구되며, 현재 노드의 참가(Join), 삭제(Delete), 사망(Death) 및 상태 오염(State Corruption)으로 인하여 발생하는 결함을 처리하기 위하여 노드의 물리적 위치를 기반으로 클러스터를 구성한 후 발생 결함을 지역화하여 처리하는 기법이 제안되었다[1]. 본 논문에서는 결함을 처리하기 위한 기존의 위치 인식 노드 클러스터 시스템에서 발생할 수 있는 헤드 노드의 결함을 효율적으로 처리하기 위한 개선된 기법을 제안하여 전체 센서 네트워크 시스템의 실질적인 가용도(Availability)를 높이고자 하며, 이를 위한 간단한 분석을 수행한 후 효용성을 검증한다.
