In this study e-map component was designed and developed to possibly overlay with all kinds of thematic maps in various scales and provide the all detailed information by using high-resolution satellite image and GIS. Also, this system has powerful map composition tool to display map such as legend, scale bar, index map and so on. For this, this e-map component was designed by using UML and developed based on Windows 2000 and implemented by using Visual Basic 6.0 as development programming language, Map Objects 2.1 of ESRI as GIS component. Through this system, the forest officials could generate more detailed topography and desired thematic map. In addition, the data consistency in DBMS could be maintained by using SDE (Spatial Database Engine) for their job and share the standard forest database with others in real time.

This paper describes the methodology of an IEC 1131-3-based control logic generator for the control system design and converting algorithm between programmable languages. The proposed control logic generator is generated based on the software model and common element with data type, variables, POUs(program organization unit) and execution control unit commonly used within programmable languages of IEC 1131-3 Standard. The generation method of object file was proposed on five programmable language based on IECI 131-3. The generation method of object file is represented as following; 1) the generation method using conversion algorithm from LD to IL with FBD(function block diagram), 2) the generation method using C code generation algorithm from SFC using the SFC execution sequence with FBD and ST(structured text). The proposed control logic generator was implemented by Visual C++ and MFC on MS-windows NT 4.0

This thesis describes the effective interfacing methods of PACS Modality based on the system installation andoperating experiences. PACS(Picture Archiving and Communication Systems) is a system for medical image archiving and communication using large storage device and high-speed network. The standard communication protocol of PACS is DICOM(Digital Imaging and Communication in Medicine) based on TCP/IP and point-to-point protocol. However, there are many Non-DICOM Modalities and DICOM Modalities having problems. First, we had interfaced almost modalities. Fuji CR, GE CT, MRI, Angio, Fluoro, Phillips Angio, Shimadzu Fluoro. Ultrasound PACS, with the main PACS in the Seoul S Hospital as large scale hospital. And we manipulated the intelligent image distribution and the CT. MRI Interfaces never experienced beforein the Anyang J Hospital and the Chungju C Hospital as mid or small scale hospital. Technically, we developed both the DICOM Interface and the Non-DICOM Interface. At the last, the DICOM Worklist and the DICOM Print Interface were implemented in the Seoul B Hospital, the Bucheon SJ Hospital and the Seoul K Hospital independently with PACS. The Oracle, Sybase and MS-SQL are used as database, and UNIX, Macintosh, MS Windows as operating systems. And the Visual C++ and UNIX C are the main programming tools. We have used UTP, coaxial and fiber optic cable under 10/100 mbps LAN for networking.

Daylighting is a powerful vehicle of architectural expression and provides buildings a living quality due to constantly changing properties in intensity and color. As an environmental system, daylighting should be subjected to the same level of rigorous analysis and review that any environmental system receives. For example, increasing cooling loads and causing visual displeasure are easily occurred owing to the excessive sunlight through windows. Therefore, daylighting performance attributes and physical characteristics must be described qualitatively and quantitatively in early design process. In various architectural daylighting performance evaluation methods, the scale model experiment can be applied due to it's simplicity and usefulness. So, this study aims to evaluate the validation of scale model experiments in architectural daylighting performance. For the purpose, two scale model experiments under clear sky are conducted. And, the validation of the experiments are evaluated by computer simulations.

This study examines the influence of fluctuating daylight illuminance on daylight dimming control systems. Field measurements were performed for a full-scale mocked-up model under various daylight conditions in winter. Fluctuating ranges for a partially-shielded photosensor were great when the variation of sky ratio was great. When solar altitude was lower the illuminance and fluctuating range of illuminance were great due to the influence of direct components of daylight and the interrefelction between surfaces in rear area of space. It implies that daylight dimming system would not function effectively, unless the desktop illuminance by daylight is enough. Fluctuation ranges of photosensor illuminance were lower than 50 lx under clear sky conditions, but they were greater than 100 lx under partly-cloudy sky conditions. It means that the fluctuation range of electric light output of lighting fixture would greater under the partly-cloudy conditions and cause potential visual annoyance to occupants. Outdoor vertical illuminance reaching the windows would be an effective factor that can be used to predict the fluctuation of photosensor signals for effective controls of daylight dimming system.

This study is to research technical measures for improving energy efficiency in the conservation and reuse of historic buildings focused on the recent research trends and case studies of the west. These measures are broadly classified into three types, the passive measures for saving energy and increasing comfort, the most cost-effective energy saving strategies, and the renewable energy sources. Firstly, the passive measures are divided into the elements and systems. The passive elements are awnings and overhanging eaves, porches, shutters, storm windows and doors, and shade trees. There are also the natural ventilation systems such as the historic transoms, roofs and attics to improve airflow and cross ventilation to either distribute, or exhaust heat. Secondly, the most cost-effective energy efficiency strategies are the interior insulation, airtightness and moisture protection, and the thermal quality improvement of windows. The energy efficiency solutions of modern buildings are the capillary-active interior insulation, the airtightness and moisture protection of interior walls and openings, and the integration of the original historic window into the triple glazing. Beyond the three actions, the additional strategies are the heat recovery ventilation, and the illumination system. Thirdly, there are photovoltaic(PV) and solar thermal energy, wind energy, hydropower, biomass, and geothermal energy in the renewable energy sources. These energy systems work effectively but it is vital to consider its visual effect on the external appearance of the building.

Visual FoxPro를 사용하여 한글 사용과 대용량 정보처리에 문제가 없고 비전문가의 사용이 용이한 전문가 시스템을 개발하였다. 본 시스템에서는 추론 방식으로 패턴매칭을 이용한 순방향 추론을 채택하였으며, 지식베이스는 IF∼THEN 규칙으로 표현하였다. 또한 추론결과의 확신도 계산에는 MYCIN 규칙을 이용하였으며, 윈도우에서의 추론을 위한 제반 자료와 규칙의 수정과 보완이 용이하도록 컨트롤 기능을 채택하였다. 개발된 추론엔진, 데이터베이스 그리고 사용자 인터페이스를 기반으로 모이와 토마토를 대상으로 한 생육장해진단 관련 데이터 베이스를 구축하여, 농민과 같은 비전문가의 활용이 용이한 생육장해 진단용 전문가 시스템을 개발하였다. 개발한 시스템의 사용상 편리성과 정확성을 농민과 농업 종사자들을 대상으로 조사한 결과, 사용자에 따라서 결론의 확신도에는 약간씩 차이가 있었으나 관행의 장해 진단방법과 비교할 때 유용한 것으로 나타났다. 또한 개발된 전문가 시스템의 기본 구조 및 추론엔진은 오이와 토마토 이외의 농작물 생육장해 진단에도 해당 데이터 베이스의 변경을 통하여 직접 응용이 가능할 것으로 기대된다.

본 논문에서는 기존의 사진영상 속의 피사체위치를 확인 가능한 시스템으로써, GPS의 사진촬영 위치와 자이로캠퍼스의 방향각을 통해 사진영상 속의 피사체위치를 확인 가능하도록 시스템을 설계하였다. 또한 설계된 사진영상의 피사체 위치확인 시스템의 검증을 위해 윈도우 운영체제의 환경과 임베디드 환경에서 각각 구축하였다. 임베디드 시스템의 개발환경으로는 S3C2440A & PXA270 프로세서를 사용하였으며, 개발보드에는 Camera와 GPS, 자이로캠퍼스를 포함하고 있으며, 개발언어는 C언어로 구현하였고, 디버깅 환경은 Linux환경의 GCC 컴파일러를 사용하여 디버깅을 하였다. 검증을 위한 PC용 소프트웨어는 비쥬얼 C++ 를 사용하여 검증 소프트웨어를 개발하였으며, 사진영상의 피사체 위치확인을 위해 알맵, 구글어스를 통해 확인할 수 있도록 시스템을 설계하였다. 또한 사진영상 속에 위치정보를 포함함으로써 사진파일을 다양한 분야로 활용하기 위한 방안을 모색하였다. 검증결과 기존의 GPS의 오차범위인 반경 10m의 오차범위가 1m 이내로 줄어들었음을 확인하였다.
