Purpose: The objective of the present study was to develop and evaluate a legal communicable diseases (LCDs) electronic system for infection control. Method: The system was developed through the procedure of analysis, design, implementation, application and evaluation, and was applied within an OCS (order communication system). Results: As indicated by the main menu, the present system is composed of an improved perception system for enhancing perception of LCDs, LCDs identification system, and improved efficiency in the report system. Detailed items included in the main menu are introduction and log-in screen, pop-up window for checking the outbreaks of LCDs, decision making icon, electronic signature icon, electronic report form, email system, etc. The total number of reports was greater after the application of the system (n=99) than before (n=80), and the adequacy of report time was statistically significantly higher after application of the system (P<0.05) Conclusion: The present system suggests a new method for LCDs report and infection control, and is expected to be adopted by other medical institutions in the future.

In the large and multifunctional engineering system, the heterogeneous computer system situation is inevitable. Accordingly a lot of integration efforts are being made to comply with the industrial requirement of productivity. In this paper, a practical concept of integration is introduced through the development of a prototype system for ship outfitting design which is a typical example of large/multi-functional application system. On the development of the prototype system, three points are considered as a practical concept-which are integration of database, integration of application programs, and system-user interface. The relation model based commercial database management system(RDBMS) is used to build the project integrated database, and the graphical user interface tool(OSF/Motif) on X-window system is used for the integration of application programs and the user interface.

Commercial video scope use CCD sensor and frame grabber for image capture and A/D interface but application limited by input resolution and high cost. In this paper we introduce portable video scope using CMOS sensor, USB pen and tuner card (low frame grabber) in place of commercial CCD sensor and frame grabber. Our video scope serves as an essential link between advancing commercial technology and research, providing cost effective solutions for educational, engineering and medical applications across an entire spectrum of needs. The software implementation is done using Direct Show in second version after initial trials using First version VFW (video for window), which gave very low frame rate. Our video scope operates on windows 98, ME, XP, 2000. The drawback of our video scope is crossover problem in output images caused due to interpolation, which has to be rectified for more efficient performance.

기상청 국가기상위성센터에서는 우주기상 업무의 일환으로 국내 GNSS 관측자료를 이용한 기상 및 우주기상 활용체계를 구축하였다. 본 연구에서는 국내 GNSS 관측망 자료를 이용한 준실시간 전리권 총전자밀도(TEC) 산출 시스템을 소개하고 산출된 결과를 제시하고자 한다. 국가기상위성센터의 준실시간 전리권 총전자밀도 산출 시스템에서는 국가지리정보원, 한국천문연구원, 위성항법 중앙사무소 및 기상청, 총 80여개의 GNSS 관측자료를 수집하고, 수집된 자료에 대하여 24시간 시간 창 기법(Time Windowing Method)을 적용하여 각 지점별 전리권 TEC 자료를 매시간 산출하고, 산출된 각 지점별 IPP(Ionospheric Pierce Point)에서의 TEC 값을 반스 내삽(Barnes Interpolation)을 사용하여 한반도 상공의 전리권 총전자밀도 격자자료를 생성하였다. 생성된 TEC 격자값을 IGS(International GNSS Service)에서 제공하는 전지구 전리권 총전자밀도 지도와 비교한 결과 한반도 상공의 전리권 상태를 더 잘 기술할 수 있음을 보였다.

Electron beam generator of cold cathode type has been developed for industrial application, for example, waste water cleaning, flue gas cleaning, and pasteurization etc. The operational principle is based on the emission of secondary electrons from cold cathode when ions in the plasma hit the cathode, which are accelerated toward exit window by the gradient of an electric potential. The characteristics of secondary electron emission are studied by comparing total cathode current with ion current.

In automobile glass fitting the stud is welded on the window seating panel in order to insert the plastic molding onto the stud. Since this type of process is in general manually done, almost 50% of the output turns out to be failure resulted from work inefficiency and weld inferiority. Therefore, it is required to improve this process for the productivity elevation through the application of the robot.

Three types of the coupling structures in combline resonators are presented: magnetic, electric, and mixed coupling structures. The magnetic coupling structure is provided by the window, and the electric coupling is provided by the electric probe. The mixed coupling structure which is the superposition of the magnetic and electric coupling structures, is proposed for the electric coupling in combline resonators with easy tuning capability. The responses of each coupling structure are shown. A 4-pole combline filter is designed and fabricated as an application of those coupling structures, and shows good filter responses.

The high Tc supeconductor of ceramic oxides type was studied for finding its application field. The results reportaed in this paper on the stability of the ceramic superconductors and the resistance to ripening in the BCO liquid phase at elevated temperature opens a processing window for engineering the microstructure of large superconductor at the nanoscale level. The results suggest further that the introduction of highly efficient artifical pinning center to bulk ceramics superconductor.

본 논문에서는 실외 환경의 실시간 감시 시스템에 응용할 배경 모델링을 설계 구현한다. 일반적인 감시 시스템은 배경 모델링, 오브젝트 검출, 그리고 오브젝트 추적으로 나뉜다. 실시간으로 배경 모델링과 갱신을 수행하고 객체를 추적하기 위해서는 연산 시간이 적어야하며 노이즈 제거를 수행해야 한다. 노이즈 제거를 위하여 메디안 검출 방법을 이용하고 있으나 정렬 시간이 많은 문제점이 있다. 본 논문에서는 윈도우 기반의 러닝 윈도우 리스트 (running window list)를 제안하여 메디안 정렬 시간을 최소화하고 실시간으로 배경 모델링과 배경 갱신을 수행하는 방법을 제안한다.
