Current improvements on the standard of living reduced working hours and increased leisure time. Therefore, people's ideas on life style changed and different demands on residential environment are being made. Residents of apartment want a community facility that enables constant exchange with other residents and supports living. Ideas on how to use physical space to strengthen a community is becoming an issue these days. Community facility plays a crucial role in giving a certain characteristic to the whole apartment and improving the image as a community. It also provides a physical environment and induces active participation of community life from apartment residents. The community facility in an important environment for children, which helps them develop in growth and in society as well. Community facility is a space where children fulfill their curiosity and amusement. Since children are greatly influenced by the physical surroundings, community facility for children should not remain as a space for fun but should change into a space for interaction. This study chose six apartments at Dongtan New Town, located in Hwaseong, Kyunggido. This study focuses on the characteristics of design for children's community facility and would like to make a proposal about future space planning for children's community facility.

In most productive facility of pharmaceutical companies, the fumigation using formaldehyde gas has been put into operation. Because formaldehyde gas is so bactericidal as to sterilize bacterial spore which can not be sterilized with usual disinfectants, it has been used for fumigation in many facilities such as facility of experimental animals, research institute and productive facility of pharmaceutical companies which are required to be high level of biological clean. However, the use of formaldehyde is recently under the strict management because of its causing of sick house and carcinogenesis. We introduce the conditions of sterilization using formaldehyde gas, the examples of sterilization using formaldehyde gas in a pharmaceutical manufacture and the problems of use of formaldehyde against environments and health. Further, we describe the characteristics and future subjects of the sterilization method using gasified oxidants such as hydrogen peroxide, peracetic acid and chlorine oxide.

Purpose: While Japan undergoes super aged society, Japanese Elderly Facilities are trying to keep elderly residents from social isolation and expand regional interaction. Methods: This study analyzes regional linkage characteristics through 8 cases of Aichi-Elderly Facilities which realize regional interaction and symbiosis(life together) between various generations by visiting. Result: 1) Most researched facilities except SO provide and share opportunity for interaction with community and residents through space for regional interaction including cafe and various programs and interactive settings. 2) The facility which seeks regional linkage through Mixed-use of facilities can devide into (1) Mixed-use of facilities easy to found, (2) Addition of housing function (NM, SM, DM) and (3) Mixed-use with different facilities(HY, GM) 3) The characteristics of interaction and symbiosis between generations are (1) to adopt concept of life together to have interaction possibility with young generation and children: most studied facilities except SO (2) to establish elderly residence into facility to have interaction(FE, SM, GM) or place family room or single room into elderly residence (NM, DM, BN) (3) to disperse small facilities into community (FE) or facility or community realizing symbiosis through various facility arrangement (SM, GM). 4) Therefore, this study can categorize (1) Program network, (2) Temporary interaction, (3) Symbiosis residence, (4) Symbiosis community according to characteristics which regional linkage has. Implication: Regional Linkage is an important concept to improve social interaction in community-based facilities. It is a thought-provoking concept to Korean elderly facilities because Korean facilities are still far from a city and in isolated environment.

This study aims to evaluate the optimal size of the hydrogen facility to be installed in a zero-energy district in terms of load matching and facility efficiency. A mismatch between energy generation and consumption is a common occurrence in zero-energy districts. This mismatch adversely effects the energy grid. However, using an energy carrier such as hydrogen can solve this problem. To determine the optimal size of hydrogen fuel cells to be used on-site, simulation of hydrogen installation is required at both district-and building- levels. Each case had four operating schedules. Therefore, we evaluated eight scenarios in terms of load matching, heat loss, and facility operational efficiency. The results indicate that district-level installation of hydrogen facilities enables more efficient energy use. Additionally, based on the proposed model, we can calculate the optimal size of the hydrogen facility.

To realize the global standard of the assembly facility, one of key point is an influence of local characteristic. The global standardized information could be a useful input, especially at the beginning stage of the project. The content should be carefully checked against local requirements, in order to develop an Assembly Facility design to meet local regulations & characteristics. The level of input information required in each step is different depend on regions & countries. At an execution stage of the project, the global standard input needs to be updated as customized final input for the construction. There will be many issues to be clarified and coordinated so that the Assembly facilities meet the final requirements for the production technology. As a result, it is important to understand the timing to use the global standard information and the contents what is needed to adapt to the local characteristics. And close collaboration between production technology team and facility team is always required.

A tree structure model has been proposed for representing the unequal-area facility layout. Each facility has a different rectangular shape specified by its area and aspect ratio. In this layout problem, based on the assumption that the shop floor has enough space for laying out the facilities, no constraint is considered for a shop floor. Objectives are minimizing total part movement between facilities and total rectangular layout area where all facilities and dead spaces are enclosed. Using the genetic code corresponding to two kinds of information, facility sequence and branching positions in the tree structure model, a genetic algorithm has been applied for finding non-dominated solutions in the two-objective layout problem. We use three kinds of crossover (PMX, OX, CX) for the former part of the chromosome and one-point crossover for the latter part. Two kinds of layout problems have been tested by the proposed method. The results demonstrate that the presented algorithm is able to find good solutions in enough short time.
