In this paper, fuzzy logic based active ventilation system with security function is proposed and implemented. We can easily experience the situation that inner air is so hot to get start immediately after parking at summer day. Hot temperature is enough to explode a gas lighter or to suffocate a little chid. Proposed system has 1 blower and 2 axial fans to ventilate inner air. Based on the fuzzy logic, speed and direction of each fan are controlled. In addition to controlling fans, controller put down windows and adjust the periods of open time. In order to prevent the theft and security problems, IR sensors are used to detect objects. On detecting objects, controller put up windows. Experimental result shows that implemented system can be effectively ventilate inner air and reduce temperature. Proposed system can be applicable to commercial automobiles.

본 논문은 초고속 통신 사업자가 적은 비용으로 고효율의 광 통신망 구축을 할 수 있는 설계 방안에 대해 제시한다. 하나의 광 코어를 사용하여 다중의 광 신호를 전송할 수 있는 기술인 CWDM과 DWDM기술에 대하여 비교 분석하고, 고속의 데이터의 장거리 안전하게 할 수 있는 POTICA 재생기 기술에 대한 고찰을 통해 장거리 전송에 나타나는 광 신호의 품질 저하를 TX/RX단의 안정화를 통해 보정에 대해 기술한다. CWDM기반 선로공유장치는 4:1 집선 용 가입자 망을 제공하여 집선 효율이 8배 증가된다. This study presents the design methods that will enable high speed communication companies to establish high efficiency optical communication network at a low cost. This study compares and analyzes CWDM and DWDM technology that transmit multiple optical signals through an optic core, and describes compensation of deteriorated optical signal, which occurs long distance data transmission, through the stabilization of TX/RX terminal to enable long distance data transmission. CWDM babsed line access multiplexer increases concentration efficiency by eight times by providing 4:1 concentration subscriber network.

This paper is about implementation of intelligent robot based on home network. Existing robots are<br/> mainly stand alone type. Home network is spreading rapidly and can play an important role as a path<br/> for informations between appliances in home. Robot can be more intelligent and have versatile<br/> functions with a junction of home network. By distribution of tasks through home network, robot<br/> doesn't have to process every task. In addition, robot can access to appliances through network as<br/> appliances are added continuously. In the future, smart space in which robot behaves on various types<br/> of network is in expectation. In this research, home network based system which consists of home<br/> server, embedded robot, and intelligent robot is proposed and implemented.
