본 논문에서는 사용자와의 실시간 상호작용을 활용하여 역사적 사실을 전달하는 반응형 미디어 아트 작품 을 보인다. 본 작품은 젊은 계층의 역사적 무관심을 김이 서리는 현상에 비유하고 사용자가 서린 김을 닦음으로써 잊고 있던 아픈 역사와 마주하게 되는 내용으로 구성된다. 김이 서리는 자연 현상과 서린 김을 닦는 행위를 영상으로 표현하였으며, 서려있는 정도와 사용자의 손 움직임에 따라 영상과 음향이 상이하게 반응한다. 이는 관객의 역사에 대한 무관심을 스스로 닦음으로서 역사적 본질과 마주할 수 있다는 의미를 극대화 한다.

A new recognition algorithm which decides thge opening & the closing states of subject's eye and isn't affected by the subject's background is proposed. And it is tested in circumstances in which subject's motions are not restricted using the developed system. AERS (Automatic Eye opening & closing Recognition System) . The significant characteristic of the AERS is that it dosen't need any extra hardware except a formal CCD carmera and an image grabber but it works so well and so fast. The AFRS wcould be particularly well suited to a tray of communications of patients in a hospital, who can not communicate othertvise.

Information network technologies introduce a new education environment. Cyber education is growing rapidly as a field of practice especially in distance education system. The development of multimedia environment based on such technology as graphics, image, voice, and video, personal computer systems use has become the media for interactive teaching-teaming service. These features have made integrated multimedia education feasible. This research suggested a direction for the development of an interactive distance education system. I have developed an education system which cooperate problem bank and learning system. This system support arbitration of the relative difficulty in the problem bank database. An ongoing version of this research was evaluated. Those findings reveal several factors that influence how the proposed system can be tailored to the students' perspectives in order to come up with the enhanced version of this system.

1. Introduction of Camera Detection system Camera Detection system is an equipment that can detect realtime traffic information by image processing techniques. This information can be used to analyze and control road traffic flow. It is also used as a method to detect and control traffic flow for ITS(Intelligent Transportation System). Traffic information includes speed, head way, traffic flow, occupation time and length of queue. There are many detection systems for traffic data. But video detection system can detect multiple lanes with only one camera and collect various traffic information. So it is thought to be the most efficient method of all detection system. Though the...

A non-contact 6D motion tracking system is proposed. The system consists of two color cameras, a color image grabber and a host computer, Motions of a floating vessel was measured by the constructed system. The instantaneous forces of the floating vessel are analyzed. The floating vessel was put on the water in a small water container in free conditions. The measured forces are reconstructed by the measurement results. The system can be used to non-contact measurements for 6D dynamic analysis of floating vessels.

This paper researched about technique of Opened CNC that were able to adapt themselves to rapid development of software and hardware. It is basic research what develop a scheme whereby technic make property. This paper theorized about to realize Opened CNC Software which is developing CNC Software flow from building Windows CE operating system's image that is possible realtime acting and multitasking. And Opened CNC Software's component designed independent classified modules. Classify Opened CNC Software's component which was consisted of basic OS Kernel, NC Code parser, Servo Motor Control, Software PLC, MMI(Man-Machine Interftce). And show there's functional example

This study was performed to establish PC-based Urban Infrastructure Information System(UIIS) using GPS and TotalStation as an alternative to UNIX-based UIIS. After carryig out this study, the following conclusions were derived: PC-based UIIS costs less time and money than UNIX-based UIIS. The coordinates of the control point of the site were obtained using DGPS, then based on this point, locational data were obtained using RTK GPS and TotalStation in the site with realtime data capture to enhance the accuracy of locational data. And image data were also entered into database together with the text data. So, the multimedia database is possible in UIIS.

카메라를 통하여 실시간으로 입력되는 객체의 움직임은 잡음이나 조명의 변화에 따라 정확하게 추출하고 추적하는 것이 어렵다. 따라서 실시간으로 입력되는 영상에서 객체를 추출하고 움직임을 추적하기 위해서는 고속탐색 알고리즘이 필요하다. 본 논문은 실시간영상에서 객체의 움직임을 추출하고 추적을 위하여 배경영상의 변화에 강인한 배경영상 갱신 방법과 가변적인 탐색영역을 이용한 객체추적의 빠른 알고리즘을 제안한다. 배경영상 갱신 방법은 임계값이 실험적 기준치 보다 작은 경우에는 배경영상을 갱신하고, 큰 경우에는 객체가 유입된 시점으로 판단하여 픽셀검사를 통해 객체의 윤곽점을 추출한다. 추출된 윤곽점은 객체 영역블록의 생성과 일정한 거리를 유지하는 탐색블록을 생성하여 정확하고 빠른 객체의 움직임을 추적한다. 실험결과, 제안한 방법은 95% 이상의 높은 정확도를 보였다.

KAFASAT is a CubeSat which has a high level mission of testing the possibility of establishing the LEO satellite constellation providing the role of communication nodes and quasi-realtime image recognition of battlefield in accordance with the aspect of future-war-environment. The high level mission is developed using the Pugh selection method, which is one of system engineering tools. In order to accomplish the high level mission objectives and deduce engineering level requirements, system engineering tools such as Analytic Hierarchy Process and Quality Function Deployment are used. The subsystem synthesis in the context of system engineering process is done using a developed integrated design environment. The paper also includes the conceptual design results of the KAFASAT, which can be used as a baseline for upcoming preliminary design.
