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.

The paper analyzed the excavational data from Bupyeong-office in Ulsan county in Chosun Dynasty, examined the composition of the community estimated at station community, and studied the duration of the community by using the excavated relics. In addition, the paper compared the excavational data with documentary records, studied the location Bupyeong-office, and investigated the size of station community overall. Community compositions such as buildings, residential place, pits, stoves, hemp kilns, cremation tombs, and farming appliances were identified. When compared to excavated relics such as tiles, white porcelain jars, agrayish-blue-powdered celadons, and celadon porcelains from building, residance, and pits, the community existed during 14C~17C. The station location was on the west side to the quarters for Byongmajuldosa of the Left Gyeongsangdo at King's location according to the old maps and documentary records. It is widely expected that No, 201 foundation stone buildings at Pyungsan relic I was related to the station because there was a distinctions on the stone pillar waterway and high quality of location in the size(the front 9 sections ${\times}$ the side 1 section) and the community. According to the building's functions and duplication relations in the community, it is regarded that there were 33~40 ground buildings, 40~45 pitting buildings, storages or 15~30 other purpose buildings, and 5~7 public buildings around No, 210 building in Bupyeong-office town.

The purpose of this study was to investigate unit care characteristics of large skilled nursing facilities for the elderly, which are located in city areas, and to discuss the way of encouraging home-like atmosphere in perspective of spatial unit. First of all, the analysis of five facilities opened before 2002 was performed, based on previous studies, to compare with them opened in recent 5 years. Most of the previous facilities did not have differentiation between their residential and nursing units, and the number of residents in each unit were excessive in comparison with the standard limit(12-28). On the contrary, the facilities established in recent 5 years had systematic spatial unit structure. The residential units had basically rooms and spaces for small group and the number of elderly residents per unit was appropriate on the basis of standard limit which was suggested by Kwon(2002). The nursing units were consist of nursing station, 2-3 residential units, spaces for large group of residents, hair dressing, nurse, living assistant, bathing, storage and etc. But, there was a problem In space usage even though they have distinct unit care systems. Some spaces for groups were empty without residents, furniture, and other equipments, which were necessary for unit care.

This paper describes the plans of considering the environmental influences in the preliminary feasibility investigation of railroad work. Because the cost-benefit analysis method about the environmental costs by air pollution and traffic noise is mainly applied in preliminary feasibility investigation, not only the verification in the calculation method of these environmental costs but also the consideration in the environmental costs of the topographical damage and the ecosystem extinction by railroad work is needed. The environment-friendly plans in choosing the locations of the railroad route and station are also suggested, and they include (1) consideration of environment protection area, residential zone, and region with scenic beauty, (2) application of the existing railroad route and station, and (3) railroad route parallel to another traffic facility.

Generally in the case of mobil communication service for long distance sea, unlike heavily populated residential areas, providers need to minimize the service area per base station. Therefore, in this thesis, the 800 ㎒ CDMA system should be extended to give better long distance communication service. This model is used to predict the occurring receiving power of the mobile stations that we simulated and analyzed. As a result, the experiment demonstrated the appropriateness of predicting receiving power using this model.

This study aims to empirically analyze the impacts of the topographic characteristics of residential areas and the characteristics of land use and transportation on average trip distance of the senior citizens in Busan Metropolitan city. Multiple regression is conducted to accomplish the purpose of this study, and the conclusions and policy implications of the analysis are as follows. First, the average and standard deviation of the residential areas are significantly related to average trip distance of the senior citizens. Thus, urban transportation policies need to take account of the topographic characteristics of the residential areas. Second, average distance from the nearest subway station and density of bus stops have positive and negative association respectively. Mobility improvement polices for senior citizens should consider urban spatial structure and different approach processes to transportation facilities by modes. Third, mobility and residential environment improvement policies for senior citizens should take into account different sociodemographic characteristics by locations. This shows that the mobility convenience policy for senior citizens is more necessary than any other policy for administrative dong, where traffic access is relatively low and the single senior citizen population is concentrated.

Purpose: The problem of housing poverty among young people is a very important problem for the nation. Therefore, the main purpose of this paper is to identify the problems of the government's housing support policy for young people. And it is in presenting specific solutions by fully reflecting the opinions of experts. Research design, data and methodology: This study consisted of analyzing the following three research topics: 1) the differences of youth residential support housing policy impact on young adults' housing stability, 2) the problems and solutions of youth housing support policy, and 3) the differences of experts' opinions on the impact of government policy on youth housing stability. The subject of this study is the government's seven housing policies for young people. The targets include Happy Public Rental Housing (Happiness Housing), Station Area Rental Housing for youth (Station Area 2030), Public Dormitory for College Students (Public Dormitory & Hope Dormitory), Jeonse Rental Housing for College Students (Subject Lease Rental Housing for College Students), Social Housing for Young People, and Share House. The data was organized through expert surveys from 1st to 30th June 2020. The experts surveyed include professors & researchers, public officer & public institutions staff, and private developers of young adults' housing. The methodology of analysis on the problem and the solution of government policy was Frequency analysis. And analysis methods on differences of experts' opinion were ANOVA, Levene' test, and Schefe test. Results: Problems in Government's youth residential support housing policy include high rents, lack of supply, difficulty in acquiring rental housing, inconvenience in using shared spaces, conflicts with cohabitants, and invasion of privacy. Solutions include expanding supply to urban areas, establishing long-term plans, securing privacy, diversifying business methods, establishing platforms for rental housing transactions, and expanding various public support (financial support, etc). Conclusions: There was a difference in perception among groups of experts on the impact of public rental housing (called 'happiness housing') in youth housing stability. It is very urgent to come up with the most reasonable policy to support youth housing. This requires in-depth discussions by experts to narrow their differences.
