블루투스는 무선 홈 네트워킹을 구성하는 하나의 기술로 자리를 잡았지만, 기존의 홈 네트워킹을 구성하는 IRDA, 무선랜, Home RF, ZigBee 등에 비하여 블루투스 사용으로 인한 큰 이득이 없어 이용되지 않는 것이 현재 블루투스가 직면한 문제이다. 비슷한 통신반경을 지원하는 IRDA와 비교하면 가격과 전력소비에서 블루투스의 이점이 떨어지고, 다중 연결을 지원하는 장점에도 불구하고 10m 내의 전송 반경으로는(저 전력 사용 시) 집안을 전부 커버할 수 없기 때문에 무선랜에 비해 홈 네트워킹에서 이용성이 떨어지는 것이 사실이다. 하지만 이런 블루투스의 AD-HOC 라우팅을(1:1 혹은 1:다) 위한 블루투스 프로토콜 스택에 라우팅 프로토콜 스택을 추가함으로써 블루투스가 장착된 정보 가전기기는 주변으로부터 라우팅 정보를 수집하게 되고 라우팅 테이블을 구성할 수 있게 된다. 그러므로 전송 범위의 이상적인 설계에서 무선랜보다 넓어지게 되므로 홈 네트워킹에서 블루투스 사용의 단점이 보안됨은 물론 집안을 하나의 WEB처럼 구성할 수 있게 된다. 이에 다른 기술에 비한 저렴한 가격, 접속의 용이성, 저 전력 소비 둥과 같은 기존의 장점에 전송 거리의 단점이 보안된 블루투스 라우팅 프로토콜 기술은 IRDA, 무선랜보다 기술적 우위를 가짐으로써 홈 네트워킹에 적용이 많아지리라 예상할 수 있다. 더 나아가 블루투스 기술이 포함되어 있는 모바일 기기가 정점 늘어남에 따라 모바일 기기와의 연동에 의한 홈 네트워킹이 실생활에 적용되리라 예측되며, 집뿐만 아니라 어디에서나 다른 모바일 기기와 연결되어 네트워크를 이루는 유비쿼터스 네트워킹이 실현 될 수 있으리라 본다.-filtered CU)과는 비슷한 결과를 보였다. 결과적으로 제안된 방법은 전통적인 켑스트럴 평균 차감법에 기반하여 효과적인 채널 정규화가 가능하다는 것을 보였다.ttention since the operation of local autonomy in Korea.

The purpose of this study is to evaluate the imbalance of green space using various spatial analysis methods and to establish the management zone for green space with service supply in the aspect of its use in Daegu. The total green space of Daegu is 48,936.1ha which is the second among 7 metropolitan cities of Korea. According to the imbalance analysis of green space, the Gini's coefficient based on the area was not high, on the other hand, the Gini's coefficient based on the population was high by above 0.6. According to an evaluation of service supply of green space in Dalseo-gu, the area within about 100m around large green space was supplied with green spaces of above $25m^2$/pop. On the other hand, the area such as Sangin, Jukjeon, and Yongsan was not almost supplied with green space. Finally, 'Rich zone', 'Fair zone', 'Poor zone', and Broken zone' could be established based on the service supply for the management direction of green space. The findings from this study can be used as the basic data for selecting the construction priority of new green spaces.

The purpose of this study is to establish the evaluation model through the systematic process of selecting the indicators and to evaluate the environmental-control function on forest using GIS in Deagu for the sustainable forest planning. The 35 indicators as basic items were selected by literature review and those were squeezed into the 29 indicators through expert brainstorming. Also, the 8 indicators to evaluate environmental-control function were selected by the first survey and the 5 final indicators such as carbon sink, temperature decrease, wind formation, water circulation, air purification were determined by MCB analysis using the second survey. The evaluation model was established through the weight of each indicator by AHP analysis using the third survey. According to the result of evaluating the environmental-control function on forest, the functions around the top area of Mt. Ap, Mt. Biseul, Mt. Palgong had more than 66 scores. On the other hand, the functions around Mt. Waryong and forest of Chilgok in Buk-gu had less than 40 scores. It is necessary to improve the function through the sustainable restoration and management in case of forest that the environmental-control function was lower. Furthermore, these results will be able to be utilized as basic data in order to establish the preservation area and control development area at the urban, environmental, and forest planning.

The purpose of this study is to examine the relationship between land use patterns of riparian zones and water quality in the Geumho River watershed. A GIS database included digital land use maps (1:25,000), stream network extracted from digital topographic maps (1:5,000) and riparian zones maps by multi-buffering method. Pearson's correlation analysis was used to explain the relationship between the environmental conditions of a 30 meter buffer strip on each side and water quality. According to the result of investigation of riparian-level land use patterns, sub-watersheds on the lower Geumho River including Daegu metropolitan city were mainly developed as urban area such as residential, commercial and industrial ones, while sub-watersheds on the middle Geumho River and the main course of Nakdong River, agricultural ones such as a paddy, a dry field and an orchard. Meanwhile, the area-rate of riparian forests which play an important role in filtering nitrogen, phosphorus and sediment was estimated below the average 16%. The proportion of urban area in a 30 meter riparian bufferstrip had a negative correlation with water quality in each sub-watershed. But the proportion of forest area had a positive correlation with water quality. Henceforth, it is necessary to establish landscape planning for preparing and restoring the riparian buffer zones, concerning land form, soil type, the present land use pattern and economic aspects.

Importance-performance analysis (IPA) is a simple and effective technique that can assist practitioners in prioritizing customer attributes to enhance service quality and visitor's satisfaction. The purpose of this study is to use the IPA-Kano model to examine the correlation of visitor's satisfaction and management matters and deduce the management priority. It classifies 14 visiting satisfaction attributes into basic factors (forest environments and staff/information center), performance factors (the natural landscape, trail facilities, forest status, easy access, and historical and cultural resources), and excitement factors (the value of natural monument, educational experiences, and entrance fee) to select the management priority according to the achievement (satisfaction). The management priority according to the performance is staff/information center > easy access > forest environment > trail facilities, historical and cultural resources, forest status, and natural landscape > entrance fee and educational experience > value of natural monument. By considering their performance, it further identifies development priorities for visitor's satisfaction improvement. These priorities allow local governments to deploy scarce resources to improve satisfaction.

Vegetation phenology is the most important indicator of ecosystem response to climate change. Therefore it is necessary to continuously monitor forest phenology. This paper analyzes the phenological characteristics of forests in South Korea using the MODIS vegetation index with error from clouds or other sources removed using the HANTS algorithm. After using the HANTS algorithm to reduce the noise of the satellite-based vegetation index data, we were able to confirm that phenological transition dates varied strongly with altitudinal gradients. The dates of the start of the growing season, end of the growing season and the length of the growing season were estimated to vary by +0.71day/100m, -1.33day/100m and -2.04day/100m in needleleaf forests, +1.50day/100m, -1.54day/100m and -3.04day/100m in broadleaf forests, +1.39day/100m, -2.04day/100m and -3.43day/100m in mixed forests. We found a linear pattern of variation in response to altitudinal gradients that was related to air temperature. We also found that broadleaf forests are more sensitive to temperature changes compared to needleleaf forests.

This paper is on a participatory spatial design methodology using Virtual Reality, which can be applied to the overall spatial design process. Participation in the current spatial design has several limitations: one-sided communication process, difficulty of understanding the given information and partial participation in the design process. Virtual Reality can be an ideal visualization tool for Geodesign and PPGIS(Public Participation GIS), which is presented as a highest step at the participation ladder. A participatory methodology is proposed to take advantage of Virtual Reality. In order to support participation through Virtual Reality in spatial design process, theories about the participation are compared to derive the new roles of Virtual Reality and the roles are formulated in the participatory spatial design methodology. By applying the methodology to the design process and implementing each stage through Virtual Reality, the design performance of each step can be verified in the methodology. As a result, design ideas can be effectively understood through Virtual Reality experiences. It is also confirmed that the interactions in Virtual Reality and participation are possible in the entire design process.

The purpose of this study is to understand the master plan of "The project on a comprehensive village development with a unit of a based township" through the master plan analysis and to help understand the implications of this project in order to maintain rural villages that can make local residents satisfied with them and promote the project of comprehensive rural village development as a successful way based on a comparative analysis through the in-site survey. The processes of this study are as follows. First, the analysis of development planning created a drawing based on linking business strategy by each region. The current situation and characteristics of planned public spaces were analyzed through the analysis of location and distribution of public spaces and facilities. Second, the situation analysis was performed by the task of shooting based on the basic plan information, and the master plan and status were confirmed through interviews. Also, the analysis of location and distribution of public spaces and facilities was conducted by a created drawings based on a survey. Finally, the detailed information of public spaces and facilities was compared with the investigation by in-site survey and analyzed through the Master Plan Strategy and a detailed classification of the types of facilities among each regional issues. In addition, by overlapping the planned drawings with the results, the results of formations were confirmed and the planned positional changes and the distribution of facilities were analyzed. As the results of "The project of comprehensive village development with a unit of based township", it was determined that there were many issues on cultural and welfare facilities in this project to meet the business objectives. Also, the facilities the residents needed, identified by interviews, were rural tourism facilities. According to the results, the residents cherished rural tourism facilities as much as basic living facilities. However, as the results of comparative analysis of public spaces and facilities, it was confirmed that mostly the plan was unfulfilled. Therefore, it is concluded that living, cultural and welfare facilities in the township can be maintained and expanded comprehensively as a purpose of "The project of comprehensive village development with a unit of based township" after not only planning process but also the project is fulfilled actually in rural areas.

This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25,000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.
