The purpose of this study is to identify landscaping costs for apartment landscapes, landscape facility factors, and the transition of spatial composition for landscapes. In addition, based on the questionnaires and analysis results for workers in related fields such as landscape design companies and construction companies, this study aimed at acquiring results for the development of current apartment landscapes and directions for improvement in the future. Through the results, it aimed at providing basic data for apartment landscapes in the future. Results showed that there was approximately a 2.6 times increase for landscaping expenses of actual apartment landscapes, and a 7.0 to 11.5 times increase in the future can be expected. The cause of such increase is the continuously growing demand for a more pleasant environment. Landscape facilities factors have been diversified, and most facilities are used as multi-purpose spaces rather than serving simple facilities. Questionnaires and field investigations showed that water facilities underwent the biggest changes, and the cause for such changes were found to be the introduction of new facilities such as water facilities and environmental structures, as well as the creation of integrated functions and spaces. Spatial composition for landscapes showed that multi-purpose spaces were established, and for the apartment differentiation strategy, there were many different changes such as theming of green areas and places for exchange among residents. For changes, the most changes were in green areas, and studies also showed that there were many changes for rest areas as well. The cause for such change is judged to have been brought about by the increase of landscape space by placing parking areas underground, and investigations showed that compared to green areas composed of large grass patches, recent apartments are establishing diverse and experience-based green areas.

Recently, with the development of service robots and with the new concept of ubiquitous world, the position estimation of mobile objects has been raised to an important problem. As pre-liminary research results, some of the localization schemes are introduced, which provide the relative location of the moving objects subjected to accumulated errors. To implement a real time localization system, a new absolute position estimation method for a mobile robot in indoor environment is proposed in this paper. Design and implementation of the localization system comes from the usage of active beacon systems (based upon RFID technology). The active beacon system is composed of an RFID receiver and an ultra-sonic transmitter: 1. The RFID receiver gets the synchronization signal from the mobile robot and 2. The ultra-sonic transmitter sends out the traveling signal to be used for measuring the distance. Position of a mobile robot in a three dimensional space can be calculated basically from the distance information from. Three beacons and the absolute position information of the beacons themselves. In some case, the mobile robot can get the ultrasonic signals from only one or two beacons, because of the obstacles located along the moving path. Therefore, in this paper, as one of our dedicated contribution, the position estimation scheme with less than three sensors has been developed. Also, the extended Kalman filter algorithm is applied for the improvement of position estimation accuracy of the mobile robot.

The findings of this study indicate that intangible cultural properties are worth preservation and transmission and should be considered as very important as tangible cultural properties. If the studies of intangible cultural properties are continued focusing on their characteristics and formational system, they can be expressed more properly by adding new interactive elements to database and expressive requisites. New techniques introduced in this study are believed to provide people with most reasonable and developmental motives for expression of the existing intangible cultural properties. Concerning Korea's cultural properties centered on intangible cultural properties, information construction should be made with a new idea of information based on database from the previous studies. The result will be able to set an important factor to give wide publicity to our cultural identity, which is currently shown in the process of background communication, and serve as a foothold to deliver exact information to our descendants. The intangible cultural properties are our people's mental cultural heritage resources. If museums or initiator groups, which are organized to spread cultural heritages, can use them as the subjects of exhibition through information construction and visualization, it will function to maximize the educational effect of transmitting our national mental world. The development of digital environment will provide the optimum conditions and tools making it possible to visualize intangible forms and ideas in a virtual cyber space. Given these viewpoints, steady studies and efforts for the improvement of Korea's cultural image should be made in the way of intangible cultural properties as well as tangible ones. They start from the country's accurate appreciation of cultural properties and are embodied in systematic adjustment and relationship between interdependent elements.

개방형 GIS에서 GIS 클라이언트는 동일한 인터페이스를 통해 서로 다른 GIS 서버의 공간 데이터에 접근할 수 있는 장점을 갖는다. 따라서, 개방형 GIS 컴포넌트 소프트웨어는 서로 다른 GIS 서버간의 상호 운용성(interoperability)을 보장한다. 그러나, GIS 클라이언트가 공간 데이터에 접근하기 위해서 표준 인터페이스론 사용한다면, 사용자의 응답시간이 느려지는 단점을 갖는다. 왜냐하면, 상호 운용성을 위해서는 각 GIS 서버로부터 접근된 공간 데이터를 표준 인터페이스를 통해 접근할 수 있도록 OLE/DB의 로셋과 같은 공통된 데이터 모델로 변환해야 하기 때문이다. 이 논문에서는 GIS 클라이언트에서 데이터 버퍼를 통해 사용자 응답 시간의 지연 문제를 해결한다. 이 논문에서는 공간 분할에 의한 버퍼관리 방법을 설계하고, 개방형 GIS 컴포넌트 소프트웨어인 MapBase 컴포넌트를 통해 구현하였다. 또한 성능 평가 실험을 통해 이 논문에서 제안한 버퍼 관리 방법이 GIS 클라이언트에서 데이터 접근 성능을 개선함을 보였다.

GPS(Global Positioning System는 지구상에서 약 2km 떨어진 위성으로부터 송신한 신호를 수신하므로 그 수신감도가 매우 낮아 재밍과 간섭에 매우 취약하다. 따라서 GPS 수신단에서 항재밍 능력에 대한 필요성은 점점 증가하고 있다. 이러한 GPS의 취약성을 이용하여 전시 상황에서 적군은 재밍 기법을 이용하여 수신단에서 아군의 GPS 신호를 이용한 정확한 측위를 방해한다. 따라서 전시상황에 대비하여 재밍 환경에 대응하고, 측위 정보를 획득할 수 있는 방법이 필요하다. 본 연구에서는 재밍 환경에서의 측위 정확도를 향상시키기 위해 BSS(Blind Source Separation) 기법을 사용하여 GPS 신호와 재밍 신호를 분리하는 방법을 제안한다. 또 재밍신호와 분리된 GPS 신호에는 여전히 잡음(noise)이 존재해 정확한 측위 정보를 획득하기 어렵다. 따라서 잡음을 효과적으로 제거하기 위해 웨이블릿 임계화 기법을 사용한다. 실험 결과는 본 연구실에서 수행한 GPS/QZSS/Wi-Fi 밀결합 측위기법의 테스트 결과를 이용하여 재밍 환경에서의 BSS 와 웨이블릿 임계화 기법을 통한 정확도 향상을 보이며 제안한 시스템 모델의 우수성을 입증한다.
