Non-fire activated fire alarms caused by such actions as cigarette smoke, cooking, and high humidity are fire safety risk factors. In such instances, it is important to quickly locate and replace the actuated detector. However, it is difficult to locate those detectors because most do not have an address function. While new apartments can incorporate addressable fire alarm detectors, in existing apartments there are limitations in converting over to addressable detectors due to cost and power line issues. This study developed an efficient address function for fire alarms in existing apartments. The newly developed system consists of the existing receiver, and a proposed addressable repeater and detector. Utilizing an experimental setup, the performance of the proposed address monitoring system was confirmed to be stable and compatible with the receiver and existing detectors.

The maintenance and improvement of housing become more important than quantitative supply. So this paper suggests the directions to solve the current issues of housing improvement policies. In 2015, the housing improvement for the low-income has been expanded with the revision of housing benefit policy. And each related government departments are steadily carrying out various housing improvement programs. Under the current improvement policies, individual houses are being repaired according to the criteria of the target selection. And the repair allowance of the housing benefit is limited to the ownership households except the rented. Hereafter, it has to considered the review of the detailed goal setting and application problems in housing improvement policy and to consider the extension to the rented households and the raise of the income criteria of targets. Also, it needs to carry out the improvement of several neighboring houses at the same time for synergy effect other than individual house, to change the selection way of repair contractors and to secure the quality and advancement of the improvement.

The technology-intensive unit modular method of factory production method is attracting attention by the limit of the labor-intensive and field centered wet construction method. In recent years, the unit modular method has been applied to the construction of schoolhouse and BOQ(bachelor offices' quarters), dormitories, etc. But the modular method still is not used in housing construction by the lack of verification of resident performance and construction cost. Therefore, this study analyzed the economics of modular house to vitalize the constructed residential building by modular method and to develop the modular method. According to the study results, the construction cost of the modular house was analysed more about 6.2% expensive than that of the existing housing. However, if the construction duration of modular house is shortened or the productivity of modular house is increased, the construction cost of modular house will be similar to the that of the existing house.

The Schwabe's law explains the housing demand weighs more on demographic factors rather than on socio-economic factors as societies achieve higher level of economic development. Based on Schwabe's law, the present study constructs a hypotheses to analyze changes of housing demand with respect to housing tenure change in Seoul Metropolitan Area (SMA) during the periods of 1980 to 2005. To test the hypotheses, the authors take advantage of the Population and Housing Census 2% data from 1980 to 2005. The authors apply binary probit with decomposition method to verify our hypotheses. The authors found that the influence of socio-economic factors on housing tenure have been weakened in the housing market during the periods of 1980 to 2005. On the other hand, the relative influence of demographic factors have been strengthened in the housing market during the periods. The present study concludes that housing demand in the SMA have been dramatically changed from socio-economic characteristics to demographic factors to decide housing tenure during the periods, which confirms the hypotheses of the present study.

The purpose of this study is to get some data to repair the existing apartment housings to energy saving house : The data are a repair requirement, a repair preference, and so on. For this purpose, an interview was carried out for the dwellers who is living in the estates constructed in about 10 years ago. If there would be a financial support of the government, which is to make a loan 1,400 thousand won and the 3.5% interest, then the 53% of dwellers have agreed to repair their houses. And the best preference repair item was a window, the items what is disturbed to their ordinary life would be not easy to be repaired. This survey has limited to only the apartment housings, so the additional survey will be carried out to get the data to practise the government's Green Home project for existing houses.

This study analyzed the characteristics of land use changes around urban railway stations in peri-urban mixed-use cities. The research focused on four station areas along the Gyeonggang Line in Gwangju City, Gyeonggi Province, categorized into three phases based on their opening dates to analyze land use changes. The analysis method utilized building permit registry data from 2012 to 2020 within a 1 km radius of each station, at 250-meter intervals, examining temporal, spatial, and functional distributions. Statistical analysis employed SPSS for weighted cross-tabulation to explore differences in building permits and concentration levels among various building types. The findings revealed: firstly, peri-urban mixed-use city station areas exhibited the highest number of building permits at the time of opening; secondly, significant land use changes were observed within the 500-meter radius from the station; thirdly, residential buildings dominated, reflecting a trend towards housing supply-oriented land use changes; fourthly, cross-tabulation indicated significant differences in building permits across time, distance, and type (p < 0.01). Lastly, the concentration analysis revealed that residential buildings were distributed most evenly, while buildings for educational, social, and agricultural and fisheries purposes were distributed unevenly.

Unplanned land use, that is, unplanned development, causes various negative externalities. In the past, Korea has experienced significant socio-economic costs due to reckless development centered on the boundary between urban and non-urban areas.. Unplanned land use can be viewed as a result of the interaction of various factors.. Therefore, it is difficult to develop in areas where unplanned land use occurs intensively. It is necessary to strengthen legal and institutional measures so that negative externalities do not persis. In this study, we present a spatial analysis methodology to effectively find spatial clusters where unplanned land use is concentrated. By demonstrating and applying this to individual development activities that occurred in Asan City, we examine the usefulness of information to support decision making when establishing mid-to-long-term growth management strategies at the local government level.

Korean urban development cooperation is gradually expanding into Latin America and the Caribbean (LAC) region, but strategies to encourage domestic market players to participate are insufficient. This paper investigated the Colombian urban planning system, urban development projects, and Korean projects in Colombia, which leads to implications for international cooperation in LAC. This research, first, compares the national and regional urban planning systems of Colombian major cities, Bogotá and Medellín. Second, case studies are carried out with a land readjustment project, a Macro project for large-scale public rental housing supply, and urban development cooperation between Korea and Colombia. By doing so, the role and the directions for Korean urban development cooperation with LAC such as Colombia are discussed and proposed. The findings suggest, first, aid projects through Official Development Assistance (ODA) should establish urban networks in recipient countries. Second, it is necessary to understand the financing structure for urban development cooperation projects that are different from infrastructure projects. Third, the successful case of urban development cooperation should be demonstrated by making the development period and size optimal and manageable.

Consolidation behavior of soft clay is generally to be affected by its compressibility and deformation characteristics. Especially, soil permeability depends on soil characteristics including its type of anisotropy. Coefficient of permeability of soft clay is mostly estimated by using laboratory(Oedometer test) and in-stiu piezocone test. The permeability characteristics of soft clay is estimated by excess pore pressure dissipation test results. In this study, the tests were performed to find out the validity of the existing theoretical formula in clay by pore pressure dissipation test and laboratory test results. After grasping of variation the coefficient of permeability ratio(${k_{h}/k_{v}}$) in different clay soils, it was found out adequate solution of in-stiu permeability ratio(${k_{h}/k_{v}}$). Piezocone tests and laboratory tests were performed at the site of pilot project of ground improvement at Yangsan-Mulgeum, Gyeongsangnam-do. Comparisons of the estimated values of ${k_{h}/k_{v}}$ using piezocone tests results and those from laboratory consolidation tests were carried out. Test results show that values of ${k_{h}/k_{v}}$ by piezocone test result(5.85) is similar of it's laboratory test(5.28).
