We have carried out the construction of the 154kV intelligent substation with KEPRI. The Intelligent substation is built in Gochang testing facility of KEPCO and consists of electronic instruments for GIS(gas insulated switchgear), digital control panel, remote monitoring and diagnosis system, and digital relay system. Rogowski coil type CT(RCT) and capacitive voltage divider(CVD) are introduced compared with the instrument transformer of conventional type. Digital control Panel(DCP) replaces the LCP(local control panel) which is drived for mechanical operation. For the monitoring of the condition of GIS and TR, various sensors are used. In this Paper, we mention the synopsis and report the progress state of project.

본 연구는 모바일 환경에서의 Character Intelligent Agent (CIA)의 사용 행태를 연구하여 CIA가 나아갈 방향을 제시하는 것을 목적으로 한다. 이를 위해 문헌연구를 진행하고 이를 바탕으로 사용자와의 1대 1 심층 개인 인터뷰를 실시하여 사용자와 CIA의 상호작용 시 영향을 주는 행동, 대화, 말투 등의 사용자와 CIA의 요소를 확인하였다. 여기서 더 나아가 CIA를 대하는 사용자의 인식이 생물과 무생물로 나누어 지고, 이는 다시 사람과 애완동물, 기계와 장난감으로 나누어 지며 이에 따라 사용자가 CIA를 사용하는 행태에 차이를 보이는 것을 알아내었다. 특히, 사람으로 인식하는 사용자의 행태와 기계로 인식하는 사용자의 행태가 더 많은 차이를 나타내었으며, 사람으로 인식하는 행태가 캐릭터에 대한 긍정적 요소를 더 많이 포함하고 있다는 것을 알아내었다. 또한 추후 연구를 통해 각 요소 간의 관계를 파악하는 것을 목표로 한다.

Many new office buildings are being built as intelligent buildings equipped with building automation(HA) systems, office automation(OA) systems, and telecommunication(TC) systems in order to provide pleasant building environment and the ease of maintenance and facility management. Building control systems which are employed in intelligent buildings require varieties of advanced control systems and network systems for efficient integrated management. Design and installation of these types of advanced building control systems take a lot of efforts and also they are costly. In order to design these systems, it is necessary for the designers to have the integrated simulator including proper network system simulation. In this paper, the integrated simulator that consist of HVAC system, lighting system, elevator system, parking system based on the network system is presented. For the development of integrated simulator, AHENA which is the general-purpose software tool for a simulation with reinforced GUI is used.

데이터마이닝 기능은 문서의 구조화되지 않은 텍스트보다는 테이블과 일반적인 DB에 있는 구조화된 자료에 초점이 맞춰져 있다. 정보화의 과정속에서 많은 기업이나 조직들은 과거의 시스템을 DB로 구축하여 어느 정도 형태를 갖추게 되었지만, E-business, E-commerce가 활발해지면서 보유하고 있는 DB기반이 아닌 무작위의 새로운 데이터가 사용자들에 의해 생성되기도 한다. 본 논문에서는 이러한 텍스트 문서에 숨어있는 정보들을 발견하기 위한 텍스트마이닝 과정을 시나리오로 설정하고, 문서와 문서집합에 대해 분석도구를 적용하는 어플리케이션을 구현해 보았다. 대규모의 문서집합에 분석도구를 이용함으로써 빠른 문서처리가 가능하고 이는 사용자가 많은 양의 문서들을 다룰 때의 시간비용을 최소화시킬 수 있는 방법이 될 수 있다. 또한 마이닝과정을 통해 발견한 지식과 특징들을 기반으로 반구조화된 파일로 변환하여, 규칙발견, 데이터마이닝기법을 적용하여 의미있는 새로운 결론을 얻을 수 있을 것이다.

This study is presenting the method for an effective data transmission in MAGLEV which is now tested and intends to provide for an intelligent operation of signal system in future. To exchange a lot of information, it is ideal to adopt a digital system and a micro-based system is essential for these purposes. FSK modulation and HDLC protocol are adopted on this study and information line assembly which is used as the information exchange, as the speech communication, and as the detection of speed and position is constructed in one unit. Actually this study is produced academic achievements of the data transmission system of MAGLEV train and an advanced method of intelligent operation in future railway system.

지금까지 공동주택에서 전력감시반은 지하실에 설치된 그래픽보드를 이용하여 감시를 수행하고 있으나, 공동주택에서의 인력구조와 시스템특성상 적절한 감시방법이라고 할 수 없다. 따라서 본 논문에서는 컴퓨터를 이용한 인텔리전트 감시시스템을 제안하였다. 제안된 감시반은 직렬통신방식을 이용한 집중감시시스템으로 설비를 디자인된 화면으로 실시간 감시하고 사용이력과 고장진단을 위한 지식베이스를 구현하여 감시반 효율성의 향상과 감시반의 공사비 절감을 유도하였으며, 실시간 O.S는 Trend 940을 이용하였다.

Our society is rapidly digitalizing. The effects of his digitalization are very diverse and one of them is that our living environments are changing. Many routine places which certain activities have been taken places are changing. For example, home office, education at home using internet, home shopping, internet banking, and so on. These facts cause the home to be extended and digitalized. That is, as our living patterns are changing, the housing needs are also changing. The purpose of this study is to graspe the digital related housing needs of the residents and suggest the directions of the digital home design. The subjects were 400 housewives who lived in 85m2 sized multi-family houses in Busan. They were relatively young in their age, had high education level, and middle income. On the base of their demands, the digital home designed as follows would be desirable: 1) safe and secure design and digital system, 2) design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) the space composition different from the existing one.
