In this paper, a research and development result for the implementation of single station fixed temperature detector for residential fire prevention is described. The detector was developed for the certification in Japanese market because of very low domestic market situation. It is in the situation that there is no other regulation especially for residential detectors in Korea, Japanese case has been reviewed. Investigation of domestic legal circumstances and a comparative study for the test standard owned by KFI (Korea Institute of Fire Industry & Technology) and JFEII (Japan Fire Equipment Inspection Institute) respectively are also indicated. The detector alarms with a buzzer and an indicating LED. In the implementation ultra low power MCU(Micro Controller Unit) is applied to control the sleeping state and the monitoring state properly with low current consumption. To sense the temperature fast response thermistor is adopted in the design of fixed temperature residential detector. Automatic test function and alarm stop function are also considered in the design. The major factors which influence to current consumption are explained for the purpose of design reference. Main electronics circuit parts related to it's characteristics of the detector are described. It is explained that the measured current and experimental result of the battery discharge can be met over 10 years operation.

This comparative analysis on the project scheme of property-led regeneration of UK and Japan aimed to suggest the implications for economy-based urban regeneration of Korea. Property-led regeneration attract private capital by deregulation and public investment since 1980s' neoliberalism. Its effectiveness for creating job and economic growth is demonstrated through last decades. The cases of property-led urban regeneration of 2000s, such as Stratford, King's Cross, Otemach and Shinonome, show decrease of public direct investment, promoting deregulation. It also proved that property-led urban regeneration has a great ripple effect to local economy. And the partnership among central and local governments, public development corporations, private developers and other local interest groups is emphasized for delivering successful urban regeneration. Especially, human empowerment of local government and responsibility of public organization are also required to deliver urban regeneration.

In Japan, bang machine has been considered to have problems about not only the impact force and frequency response which are different from the real impact sources such as children's jumping and running, but also damage in the wooden structure housing. Therefore, a new impactor for lower impact force to prevent demage in wooden structure housing was developed. The impact ball was adopted as the second standard impact source in JIS A 1418-2 and ISO 140-11. In the present study, floor impact sounds generated by impact ball with drop heights in four floors of mock-up building of Building Research Institute (BRI) similar to typical Japanese wooden structure housing were investigated and also compared to jumping sound. The results show that Impact ball sound dropped at 10 cm to 30 cm was most similar to jumping sound. And The impact sound levels at 250 and 500 Hz were more sensitive to drop height than other lower frequencies. The error that may occur from the difference of height of 10 cm up and down based on the standard drop height caused by the impact ball operated by human hands was approx. 1 dB or less only in its value of characteristic, but it must be carefully taken into Impact ball in the Korea Standard.

Recently, "aging in place" has become the principle philosophy of elderly housing policy in many countries. However, since there is ambiguity surrounding the universal definition of it, the meaning of AIP has been defined by political expediency. This study aims to discuss the meaning of AIP by examining the transition of elderly housing issues and policy in Japan. During the last two decades, the Japanese government has tried to launch a new elderly welfare system to shift the responsibility of elderly care from the family to the society and from the society to the region. And the focus of elderly housing policy has shifted from the promotion of three-generation dwellings to supporting the development of private residences. However, since the main goal has been limiting the welfare budgets rather than enhancing the quality of life, elderly housing issues have been reduced to a matter of choosing either elderly care facilities frequently located in suburbs or not. This paper suggest that we should pursue the true AIP idea in housing policy, and argues that to do so we need to consider AIP from diverse aspects such as temporal continuity, the range of space, the dynamics of place experience and the capability of communities.

There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

Studies about architectural planning for elderly residences have been carried out to examine various factors including the unit plan, site planning, and size planning. However, no studies have been undertaken that focus on the residents' daily life patterns. This study offers the design guidelines to support the daily life patterns of the elderly through the planning of elderly housing. For this study, elderly residents in Tokyo, Yokohama etc. in Japan were interviewed and surveyed. The results indicate that the changes to the daily life patterns of the residents living in elderly housing are the reduction of household, the increase of free time, and the change of social relationships. The elderly want to utilize their free time and focus on their social relationships. However, the elderly residences that we surveyed pay no consideration to social spaces and programs for their residents except for the cafeteria. To support the daily life patterns of the elderly, elderly housing should set a high value on the location, shared spaces, and unit plans of the residences in order to consider the personal diversity of the residents. Accessibility to public transportation systems and facilities should to be considered in the initial location planning. The revitalization of the public spaces should to be considered during the architectural planning stage. Considerations of personal taste during the unit planning stage are also necessary.

On July 2004, the brand new CASBEE for construction (Brief version) has completed while trying to highlight and improve major items adequate for each region's characteristics in Japan; at the same time, from the start of NAGOYA CITY (operated since April 2004) to the point of May 2011, it has been mandatory for specified size buildings in 23 regions by law. Evaluation sheet of CASBEE is published on each region's home page and various genre of information on building evaluation which is scheduled to be completed by 2016 and is for 5-6 years of quantity is accumulated until October 2012. It is good study resource to verify how new buildings being evaluated are closely match with CASBEE's original purport (eco-friendly, energy efficiency, publicity etc). Particularly, for Japan's multi-family housing where small sized mid to high level single housing type is majority in city, it is an important point that improved performance on eco-friendly buildings have more value in city rather than suburb. Categorized score through evaluation is a resource to confirm the latest trend of multi-family housing built in congested city; on the other hand, demand of the time can be recognized by the score focused on category. It is meaningful resource to determine the adequacy of evaluated items and the degree of reality.

This study discusses the sustainable development of the compact city. The problems of urban sprawl have long been recognized. Urban sprawl results from the confluence of several factors: the lure of cheap open land outside the city, advances in transportation, the ready availability of capital to buy property, the increase in the number of real estate developers and the mass production of housing. The term compact city has the opposite connotation to urban sprawl. Compact cities provide a more energy efficient and less polluting environment, because dwellers within them live closer to shops and work and can easily walk, bike or take public transport. In other words, the compact city has the objective of facilitating the integration of the different functions through the intensive development of various facilities, such as residences, commerce, businesses and of improving the efficiency of urban energy usage by decreasing the volume of traffic.

In modern Asia major cities had same problem with lack of affordable housing for families. So they had to concentrate to the mass supply of housing and made some physical counter effects like high density of cities, limitation of parking space. Also people who lived in those cities could suffer from broken traditional community culture. To rebuild traditional community and increase land usage, Block housing is suggested as a new kind of multi-family housing for old town redevelopment. Now some governments are trying to make urban code to give some initiative for new block housing development in old city blocks. They expect this new housing type can help to solve serious problems like lack of parking area, green space and context of block. Also they hope that block housing development can help to increase safety of town and reduce cost of development. The purpose of this study is to review the establishment and development process of Block Housing and to confirm the aspect which has been changed with urban organization together. Also this study tried to find out the intentional characteristics of similarities and differences with comparison of Korea and Japan. And as a result we could find critical physical viewpoint, and provide considerations for future study and plan. Several cases of block housing in Korea and Japan were reviewed for comparative study and Post Occupancy Evaluation (POE) survey was examined to find satisfaction factors and problems which were expected to improved.
