The purpose of this study is to analyse and derive the color characteristics of childhood children's learning spaces and furniture for improving the color design of those and to present the direction of design and to build up the DB. The study covers products from domestic and overseas infant furniture manufacturers and 11 preschool learning rooms. The study method uses the collected furniture and spatial images to derive a palette of colors and compare color characteristics. The analysis results show that, the domestic infant furniture tend to use a variety of colors with pale tone or use consistent hard wood furniture according to the requirements of adult taste and marketability. Also, it attempts to create a very negative color scheme, but it looks like disorganized, and there is not much color design integrated with the architecture. Thus, color designs ensure that the ordering elements of the color scheme are clearly recognized by applying preferred color tones of childhood, like vivid and bright tone with high chroma and middle or hight Brightness value. Lastly, it should establish guidelines for specific palettes and color scheme, which can be utilized in the design of childhood children's learning spaces and furniture.

최근에 인터넷 사용량이 증가함에 따라 자료의 양은 많아지고, 서비스 방식도 복잡해지는 문제가 생겨나게 되었다. 그에 따른 해결방안으로 P2P(Peer-to-Peer) 모델은 2000년대에 들어서 다시 컴퓨터 산업 무대의 중심으로 자리 잡게 되었다. 지금까지 잘 알려져 있는 클라이언트/서버 모델은 계속적으로 증가하고 있는 사용자와의 통신 수요에 대한 문제가 있다. 그렇기 때문에 P2P 모델은 이러한 구조에서 벗어나 사용자들 간의 직접적인 정보 교환을 가능하게 해주어 서버의 역할을 최소화 시켜 주었다. 이러한 이점 때문에 현재 많은 기업체들이 P2P 모델을 클라이언트/서버 모델 이상으로 선호하게 되었다. 자바를 이용해서 개발한 P2P용 메신저 통합 서비스에는 기존의 상대방과의 대화뿐만 아니라 파일 공유, 자료의 업/다운, 멀티미디어 채팅으로 상대방의 얼굴을 보며 대화를 할 수 있는 화상채팅 기능이 있고, 친구들을 쉽게 정리하여 사용자만이 관리를 할 수 있는 공유그룹과 폐쇄그룹을 추가하여 보안에 대비 하였다. 또 키워드 검색, 메타 검색으로 더 많은 자료를 손쉽게 찾을 수가 있다. 시스템 상에 XML, 웹 서버, WAP 게이트웨이 서버를 탑재하였고, 가상의 네트워크인 VPN 사용, 그리고 DB를 사용한 회원관리 및 여러 가지 서비스를 제공한다. 향후 P2P 기술은 P2P 검색, P2P 커뮤니케이션, 무선인터넷관련 기술, XML을 이용한 표준통합기술의 발전으로 더욱 침체된 시장에 활력소 역할을 할 것이다.

Pursuing sustainable development throughout society and industry and the field of environmental policy, each international organization or nation has performed international standardization projects on environmental management activities for their system as well as environmental assessment for a product such as life cycle assessment (LCA) and life cycle inventory database (LCI DB), and the environmental aspects have been increasingly demanded as crucial evaluation specifications. Moreover, the conventional environmental policy, which represents the direct-control, has been more dependent on the market forces and product itself after the Climate Change Convention., and the Integrated Product Policy (IPP, EU) is applied vigorously to strengthen global competitiveness of a product and to achieve the effect of environmental improvement for it. According to change of the international railway market, the value of Eco-Design has been increasingly important in developed countries including EU. Thus, each country is establishing its own guidelines, software and database for each product, and developing new policies through Eco-Design with practical results in marketing. To react this and develop Korean railway as an environment-friendly industry with priority to other transportation system as well as maintain high place in technology, the direction of RACE software development of main function is introduced, which is exclusively used for EMU to assess both environmental and economic aspects with LCA and eco-efficiency (EE).
