기존의 SOFA(Software Appliances)형의 컴포넌트에서 DCUP(Dynamic Component UPdating)통해 컴포넌트 조립이 가능하다. 이에 대해 비동기적이고 동적 시스템에 적합한 패트리 넷을 이용하여 컴포넌트의 동적 업데이 시 기존 컴포넌트와의 상호작용과 각 인터페이스에 대한 프로세스의 흐름을 정형적으로 정의하고 설계상의 모호성을 줄일 수 있도록 하였으며 보다 나은 동적 업데이트의 최적화를 위한 기반을 제공한다.

The shift to more practical and simpler lifestyle in the modern society is well reflected in people's preference when it comes to living room space and sofa designs. These elements are intentionally crafted to satisfy the customers' personal needs and wants, sense of comfort, aesthetic preference, and function. This study includes an analysis on the development and conceptualization of sofa designs, exterior materials, and colors of the furniture released by Hanssem, Livart, Borneo, Emons, and Jangin Furniture during the first half of 2007. Modern and practical sofas should be essentially designed according to the customers' demand and current trend. Such design principle is necessary to achieve and maintain competitiveness in the globalizing society.

In this paper, we propose a test method to evaluate the reliability of the recliner sofa in the early stage of production. In order to develop the test method, we analyzed the failure mechanism occurring in the field and designed the performance test, environmental test, accelerated life test methods based on the analysis of failure mechanism. The failure mechanism is reproduced by applying the designed test. The reliability of the recliner sofa can be verified at the production stage through the proposed test method.

In today's aging society, stable residential environment is essential for the elderly living alone to be able to do activities of daily living without restrictions and cherish a satisfactory quality of life. We developed a safe and convenient multifunctional sofa by removing complex combinations and decomposing processes of the multifunctional transformable furniture, appropriate for the use by elderly living alone. We deduced the 4 main keywords and details related to the purpose of sofa by analyzing the users' physical and mental characteristics through literature review and by using 24-hour scheduling, interviews, and actual measurement. Finally, by applying this to furniture planning, we designed 4 different types of multifunctional sofa system. Production was done in cooperation with AND Co. for 2 weeks using materials, colors and adhesives selectively chosen with careful consideration of their effects on the physical, mental aspects of the user to give optimal comfortability.

국내 미분탄 보일러의 로내 공기량 공급에 따른 연소특성 분석을 위한 3차원 전산해석 연구를 수행하였다. 보일러 연소해석 해석 결과의 건전성 검증을 위하여 보일러 출구, 즉 절탄기 후단에서의 가스 온도,$O_2$, NO, SOx 농도를 발전소의 실제 운전데이터와 비교하였다. 검증된 해석 결과를 기준조건으로 SOFA(Separated Over Fire Air)와 CCOFA(Closed Coupled Over Fire Air)에서의 연소 공기량을 변화시킨 경우 보일러내 NOx와 가스 온도 분포를 중심으로 각각의 경우를 비교하였다. 본 연구를 통하여 CCOFA보다는 SOFA 공기량의 변화에 따라 NOx 농도의 민감도가 더 큰 것을 알 수 있었으며 대류 전열부의 전열관군에서의 온도 분포가 다르게 나타나고 있어 가스온도 편차 방지를 위한 연소조정이 필요함을 알 수 있었다.

화재위험성이 큰 유흥업소에서 주로 사용하는 내장재중 방염 카퍼l트, 방영 후처리 합환, 쇼파 례자동 3가지 시료에 대한 연소특성과 CO, CO2, 02, NO., S02, HCN, HCl둥 독성가스를 검출하여 화재 위험 성을 비교명가 하였다. 연소특성에 있어 방염 카페트가 방염 후처리 합판, 쇼파 레자 보다 연소가 잘 되 었고, 폭연 연소가 일어났다. 모든 시료에서 CO의 발생은 연소시작 후 1분 이내에 치사농도를 상회(上 ) 하였으나 NOx와 S02는 치사농도를 상회(上 ) 하지 않았지만. HCN는 카페트에서 쇼파 레자 보 다 20.6배, 방염 후처리 합판 보다 4.6배가 검출 되었고. HCl은 차페트에서 쇼파 례자 보다 4.48배, 방 염 후처리 합판 보다 2.47배가 검출 되었다. 이상과 같이 3종의 내장재중 방염 차페트가 화재위험성이 가장 높다는 결론을 얻을 수 있었다.

The Plan for effective usage of living room must be suggested because families primarily use living room for public space. And from the viewpoint of function and decoration. the kind of furniture. furniture occupancy quantity. and the arrangement of furniture have much affect on using a dwelling space. So this study will suggest basic data for a good furniture usage through experiment using scale down models. To analyze the data. frequency and percentage were used by running SPSS $PC^＋$ program. The major results are as follows. In an experiment using living room and furniture models(Scale 1/20). according to the size of space. TV sizes and furniture occupancy quantity were in proportion to size and space of the living room. Also they chose various types of tea-table and side-tables. In small spaces. subjects chose simple arrangement types (no sofa or I type sofa and cabinet). but in large spaces. they chose \ulcorner type or \ulcorner type sofa and cabinet.

Recently, Korean society is increaseing "1 person family" phenomenon, which is influenced by changing of young peoples' value, aging society and social economic problems. Increase of single households is a result of complex economic, cultural and social factors. It is because as the individual's financial independence increases due to elevated income and education level, the age of marriage is going up and the individualism, which values the individual's value rather than custom, is spreading. Therefore, this new phenomenon will be impact to between social, economic value structure and living space. An increase with small furnitures are also increasing of R&D and marketing plans for 1 person family. Currently, 1 person family is bigger than last decade and that is requiring more suitable and multi-functional furniture for them. However, in Korea furniture companies are more optimization to traditional family size. Thus, this research explore about developing cheap price sofa bed, which is using at narrow area and small place.

This was a systemized bed consisted of storage units, a desk, a drawer, a sofa and a shelf. This bed system was not designed only for a certain age group of children but also for various age groups of children, since each parts of the bed can be sued separately. Separation of parts of the bed allowed children to decorate their own living space and gives them a chance to express their own feeling and thoughts by layout of parts. Design adopts the beauty of nature such as smoothly curve lines which are perfectly fit for the children's living space.
