Auto Pilot은 전자해도나 플로터를 이용하여 항행하고자 하는 코스를 입력 시킨 후 운행모드를 자동운항에 위치시키면 자동으로 경로를 따라 선박을 이동시키는 시스템이다. Water Jet 추진장치는 엔진과 연결된 펌프를 가동해 배 밑바닥에 있는 흡입구로부터 물을 빨아들인 후에 배 내부에 설치된 유도관을 거쳐 노즐을 통해 가속된 물을 배 뒤쪽으로 분사하면서 배를 앞으로 밀어주는 힘을 발생시키는 추진 장치다. Water Jet 추진장치는 수심의 영향이 적고, 고속영역 일수록 추진 효율이 높고 진동과 유동소음 측면에서도 매우 유리한 장점을 갖고 있어 새로운 추진시스템으로 국내외 적으로 수요가 확대되고 있다. 하지만 Auto Pilot 와 Water Jet 추진시스템의 신호 체계가 달라 상호간 효과적으로 신호를 전달할 수 있는 장치가 필요하다. 본 논문은 기존의 Auto Pilot 와 Water Jet 추진시스템의 신뢰성 있는 통신을 할 수 있도록 상호 연동하는 Interface 장치를 설계하였다.

Power system analyses, which involve the handling of massive data volumes, necessitate the use of effective visualization methods to facilitate analysis and assist the user in obtaining a clear understanding of the present state of the system. This paper introduces an interface that compensates for the limitations of the visualization modules of dynamic security assessment tools, such as PSS/e and TSAT, for power system variables including generator rotor angle and frequency. The compensation is made possible through the automatic provision of dynamic simulation data in visualized and tabular form for better data intuition, thereby considerably reducing the redundant manual operation and time required for data analysis. The interface also determines whether the generators are stable through a generator instability algorithm that scans simulation data and checks for an increase in swing or divergence. The proposed visualization methods are applied to the dynamic simulation results for contingencies in the Korean Electric Power Corporation system, and have been tested by power system researchers to verify the effectiveness of the data visualization interface.

본 논문은 인터넷으로 연결된 내장형 시스템을 효율적으로 개발하기 위하여 메소드 호출과 시그널을 매핑하는 방법을 이용하여 SDL과 CORBA 시스템을 통합하는 모델을제시하였다. SDL과 CORBA를 기반으로 하는 두개의 시스템이 통신하기 위해서는 SDL 시스템의 통신 프로토콜과 CORBA 통신 프로토콜간의 변환 인터페이스가 필수적으로 요구된다. 본 논문에서는 두 시스템간의 통신 인터페이스 및 통신 프로토콜의 변환을 위하여 IDL을 사용하였으며 IDL 컴파일러에서 프로토콜 연동을 위한 인터페이스를 자동 생성하도록 하였다. 본 모델을 이용할 경우 SDL로 작성된 서버 시스템의 하부에 미들웨어를 채용할 수있어 서버 시스템의 실행환경 및 위치에 관계없이 분산 시스템 상에서 서비스가 가능해 진다.

In this paper, we developed a Windows 95 version off-line programming system which can simulate a track vehicle model in 30 graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc were utilized for 3D Graphics.

Since 2010, issues for data sharing and data exchanging in hospital information systems have been emerged. In order to solve the issues, standards should be applied to develop the systems and there should be no ambiguities between terminologies in the systems. In this paper, the terminology mapping system for narrative clinical records was implemented. The term mapping precision was 83.4%. This system could help to upgrade the text based clinical system and it would be expected to support for high quality clinical services.
