GeoWeb services deliver various thematic information related to geographic positions over the internet GeoWeb services needs to provide efficient accessibilities to geographic contents by interaction with users through the map graphic elements. SVG, which is an application of XML, gives rich DOM I/F for interaction with graphic objects. In this study map servers and client viewers are implemented to serve SVG map available on the fixed mobile internet computing environments. Map servers are made compliant with OGC WMS and WFS specifications and SVG map viewers are developed for both Windows PC and WinCE PDA.

Recently energy crisis and environmental pollution using fossil fuel became social issue. The Fuel Cell, one of the new and renewable energy has great advantage for the former mentioned problems. The PEM Fuel Cell needs highly purified hydrogen for fuel, in many cases CH4 was reformed to H2 basically using steam reforming. The purpose of this paper is to understand the probability of ceramic honeycomb to apply the combustor of STR. We tested the heat accumulation performance of ceramic honeycomb by change of excess air ratio. The results were suitable for our purpose and also these results can be used to make high temperature air at mild combustion field.

Cadastral map is the basic data that prescribe a lot number, the classification of land category, a boundary and ownerships of the parcels. Because the analogue cadastral map is not appropriate for the Parcel Based Land Information System, computerization of cadastral map is needed. When considering other automatic vectorizing softwares, we conclude that they can not satisfy the accuracy needed in cadastral map. Also screen digitizing methods demand lots of time. So we developed semi-automatic vectorizing program that realized almost capacities, such as overlay display which is needed for screen digitizing , window link, vector file generation , and so forth. As comparing screen digitizing method using AutoCAD with our developed program, we could obtain not only almost same accuracy , but also 35 minute reduction in vectorizing.

The purpose of this study is to develop a Bridge Disaster Management System for bridge safety control using Geographic Information Systems(GIS). The constructed database includes several graphic layers such as basemap, road, bridge location, etc. and has related text attributes for 32 bridges and its facilities in Chinju City. Using the language of Visual Basic 5.0, personal computer based Bridge Disaster Management System which has several functions for bridge safety analysis was developed. The developed GIS based Bridge Disaster Management System has the functions of fast and efficient data searching, file management, searching and management of bridge characteristics, bridge related map viewing, searching and management of traffic survey, bridge inspection and repair work results, and evaluating the bridge safety grades, etc..

Two-Dimensional incompressible laminar boundary layer with the reversed flow region is computed using the parially parabolized Navier-Stokes equations in primitive variables. The velocities and the pressure are explicity coupled in the difference equation and the resulting penta-diagonal matrix equations are solved by a streamwise marching technique. The test calculations for the trailing edge region of a finite flat plate and Howarth's linearly retarding flows demonstrate that the method is accurate, efficient and capable of predicting the reversed flow region.

An eight-year-old, spayed female Shih-tzu, weighing 3.2 kg with a history of chronic intermittent vomiting and unknown pain for four months was referred. In ultrasonography, a small round hypoechoic mass was identified in the gastric wall. Gastric endoscopy showed a solitary raised mass with smooth surface in the pyloric antrum. Surgical resection was performed. Histopathologic findings with immunohistochemical studies showed extramedullary plasmacytoma in the gastric submucosal and muscle wall layer. The patient recovered normally without any complications. The tumor has not been re-occurred after surgical removal, to date.

It is difficult to extract small valve automatically in noisy 3D point cloud obtained from LIDAR because small object is affected by noise considerably. In this paper, we assume that the valve is a complex model consisting of torus, cylinder and plane represents handle, rib and center plane to extract a pose of the valve. And to extract the pose, we received additional input: center of the valve. We generated histogram of distance between the center and each points of point cloud, and obtain pose of valve by extracting parameters of handle, rib and center plane. Finally, the valve is reconstructed.

자연공원의 체계적인 관리를 위해서는 효율적인 자료수집과 처리, 그리고 합리적인 분석과정이 필요하며, 이러한 관점에서 지형공간정보체계와 위성원격탐사를 이용하는 공원관리 및 관광안내시스템의 개발이 요구되는 시점이다. 본 연구에서는 금오산 도립공원구역을 사례연구지역으로 GSIS(Geo-Spatial Information System)기법을 도입하여 수치지형도, 주제도, 위성영상 등으로부터 도형자료 및 비도형자료를 수집 처리하였다. DEM 생성을 통하여 얻어진 경사도, 사면방향, 지형단면, 지질 분석 등 주제별 지형분석을 행하였다. Landsat TM 위성자료로부터 토지피복분류와 NDVI 식생활력도를 추출하였고, 이 자료들로부터 GSIS 데이터베이스를 구축하였다. 또한 대상지역을 포함하는 Im 해상도의 IKONOS 위성자료를 처리하여 영상지도를 작성하고 DEM과 중합하여 3D 시각화를 구현하였다. 위성영상지도 및 3차원 경관도상에 주요 등산로 벡터자료를 중첩하여 표현하고, 5개 루트의 주요 등산로를 따라 3D 경관 및 문화재, 관리시설 등을 포함하는 동영상 파일을 제작하였다. 본 연구의 결과는 개발과 보존의 중도를 취하는 자연공원의 적정 토지이용을 위한 사전평가 자료 및 Web 기반 관광안내시스템을 구축하기 위한 기본데이터로 활용될 수 있을 것이다.

The digital map needs efficiently updating. Because it is a base map at each local government and several geographic information systems and that is the key to enhancing to use spatial data. We suggest the linking method of building registers to the building layers of digital map, to update attribute data of the building layers. To conduct that, it is very important that each building in two data is linked by one-to-one matching. In this paper, we generate the strategy for renewing attribute data of the building layers based on identifier by using identifier of the new address system.

This thesis is purposed to economical and rational accomplishment of the agricultural water resources development project as to utilize digital topographic information in basic investigation, preliminary planning and detail design process of the agricultural water resources development. In this study, the digital topographic data is acquired to stereo aerial photography of test field and the digital elevation model(DEM) is generated by interpolation of acquired data. Also, the database of basic investigation which is constituted to graphic and at-tribute data is designed. As the results of this study, the method that is determined to this study makes a contribution to effective accomplishment of the agricultural water resources development project.
