  • This study aims to examine the effect of housing environment on single mothers' health and to find out how to improve their health and housing environment. For the purpose, this study analyzed the Single-parents survey carried out by Ministry of Gender Equality and Family in 2015. The results are as follows. When residential functions such as mining, heating, and noise are not fulfilled among the physical characteristics of the residential environment, single-mothers are more likely to feel unhealthy. Among the socio-economic characteristics of housing, people who live in public rental housing are more likely to feel unhealthy than those living in own house. And people who have excessive household debt are less healthy than those having no debt. Socioeconomic characteristics of housing environments had a significant effect on depression of single-mothers. Based on the results, the author suggested that housing improvement services, survey of housing conditions of single parents, provision of services considering household debt and improving residential conditions of public rentals houses should be implemented.

  • Purpose: This study, which is based on the investment payback periods, aims to suggest the proper insulation level which can be adapted to the Defense Military Facility Criteria regarding the military residential condominiums. For the energy performance simulation, it is required to collect the residential data regarding the military condominiums and climatic data concerning the regions they belongs to. The estimates through energy performance simulation are the regional heating loads and the heating transmission coefficients of building components. Method: With the heating loads, the annual heating cost saving per square meters is assessed. With the heating transmission coefficients of building components, the additional insulation installment cost per square meters is evaluated. With two outcomes, one as an annual value and the other as a present value, the investment payback period is calculated. Result: In result, it could be concluded that 55~70% insulation ratio can lead a superior residental environments as well as be contributed to the national policy associated with zero-energy buildings because the estimated investment payback period is shorter than the life span of the military residental condominiums. This upshot can be used as a foundation to enactment the Defense Military Facility Criteria associated with military residential condominiums.

  • Wind environment in urban residential areas is an important index to consider when evaluating the living environment. However, due to the complexity of the flow field in residential areas, it is difficult to specify the correct inflow boundary conditions in the large eddy simulation (LES). In this paper, the weighted amplitude wave superposition (WAWS) is adopted to simulate the fluctuating velocity data, which satisfies the desired target wind field. The fluctuating velocity data are given to the inlet boundary of the LES by developing an UDF script, which is implemented into the FLUENT. Then, two numerical models - the empty numerical wind tunnel model and the numerical wind tunnel model with spires and roughness elements are established based on the wind tunnel experiment to verify the present method. Finally, the turbulence generation approach presented in this paper is used to carry out a numerical simulation on the wind environment in an urban residential area in Lisbon. The computational results are compared with the wind tunnel experimental data, showing that the numerical results in the LES have a good agreement with the experimental results, and the simulated flow field with the inlet fluctuations can generate a reasonable turbulent wind field. It also shows that strong wind velocities and turbulent kinetic energy occur at the passageways, which may affect the comfort of people in the residential neighborhood, and the small wind velocities and vortexes appear at the leeward corners of buildings, which may affect the spreading of the pollutants.

  • Apartments with a southern exposure are often thought to have advantages in receiving winter sunlights and summer natural ventilation. However, as due-south-apartments increase recently, the consideration for residential environment for households with no southern exposure is necessary. In case of due-south-apartments, residents prefer east-sided apartments than west facing apartments which might receive more hot sunlight in the afternoon; however in case of west-oriented apartments with active ventilation, the interior area is bright until late afternoon without unpleasant heat and has advantage in light environment aspects. This study aims to compare and analyze merits and demerits of air flow and sunlighted environment of buildings through sunshine duration simulation using CFD simulation ad sunlights about southeast-sided and southwest-sided apartments based on general opinions for apartment directions. As results of the interior natural ventilation analysis, as the average air flow speed in southwest-sided apartments was 1m/s faster than that of southeast-sided, it has effects of lowering sensory temperature of residents in summer, and for sunlighted environment, southwest-sided apartments are advantageous for sunlighted area for duration time inside. As a result of the research, the calculation of physical residential environment of apartment residential space should be reached through integrated evaluation of natural ventilation and sunlighted time from placement and facing direction of the buildings considering characteristics and environment of each apartment, not based on general opinions.

  • This study examined the residential environment of public rental housing by type at a microscale, using ANOVA and multinominal logistic models, based on the minimum and specific housing standards. The key findings are as follows. First, it was confirmed that each type of public rental housing, as well as resident characteristics, varied in meeting the minimum and specific housing standards. Second, Happy House turned out to have the worst residential environments, as a high proportion of this type did not meet the minimum housing standard and the remaining specific standards, excluding facility standards. Third, among permanent rental, national rental, and purchase/jeonse rental housing types, permanent rental housing was poor by the minimum housing standards, and area and room standards, while purchase and jeonse rental housing types showed a high proportion of failure to meet structural, performance, and environmental standards. Fourth, it was confirmed that purchase/jeonse rentals had higher rental anxiety than other types of public rental housing. In particular, anxiety about rent increases and the loss of deposits was high. These findings suggest that public efforts are called for to improve the residential environment through tailored support, depending on the type of public rental housing.

  • The purpose of this study was to develope a housing suitable for the Korean elderly by analyzing traditional minds on housing of the middle-aged. Data were collected by the questionnaire from 696 middle-aged in 40's and 50's living in Chinju area. Collected data were analyzed by using statistical methods of One-Way MANOVA, scheffe's test, and multiple regression analysis which were processed with SAS. Following are results. 1) Middle aged people had four main traditional factors in their minds: a propensity toward traditional indoor atmosphere, traditional housing space, traditional housing value and ceremony space & traditional life style. 2) Socio-demographically, a propensity toward traditional housing space and ceremony space & traditional life style were significantly different between sexes, but not by educational level and income. A propensity toward traditional indoor atmosphere and ceremony space & traditional life style were different between housing types. 3) However, there were a significant difference between variables such as sex, educational level, income and housing type in residential demands for the elderly life. 4) Sex, housing type, a propensity toward traditional housing space and traditional housing value influenced residential demands for the elderly life I indoor and outdoor environments, nearby facilities and available services all of which were minor items in the demand for the elderly life.

  • In many very high density cities in Asia in which there is limited area to expand, growth is forced upward as well as outward. Densely packed detached houses and low-rise buildings are replaced by lower density high-rises, leaving open spaces between high-rise buildings. Through this process, areas that formerly did not have much green space gain valuable green spaces, and new ecological corridors and patches are created. In this study, the demographic and housing-type changes of Wonju City were delineated using land use maps, aerial images, census data, and other administrative data. Green area changes were calculated using land cover data derived from multi-year Landsat TM satellite imagery. The values were then compared against demographic and housing-type changes for each administrative unit. The overall results showed a decrease of forested area in the city and an increase of developed area. Urban sprawl was clearly visible in many of the suburban areas. However, as expected, we also detected areas in which greenness did not decrease when the population greatly increased. These areas were characterized by residential building complexes of ten or more stories. If an equal number of housing units had been built as detached houses, these areas would not have kept as much green space. Our research result showed that high-density and high-rise residential structures can offer an alternative means to protect or create urban green spaces in high-density urban environments.

  • The purpose of this study is to analyze the characteristics of planning community facilities of public rental apartments by basic and qualitative factors for the last ten years from the year of 2000. This study analyzed the processes and trends of change of the following: land use, tenant satisfaction with the residential environmental amenities, the quantitative increase in accordance with social paradigms, improvement in the quality of residential life, and acceptance of the needs of residents. Therefore, this study will suggest effective and archivable improvements in them. Methods of this study include drawing analyses, literature surveys, and interviews with experts. This study aims to provide essential primary data for planning community facilities for public rental apartments in order to differentiate them from public sales apartments. In the results, community facilities of public rental apartments have been increasing in their size and in the number of their programs as well. It is certain that community facilities are important influence on improving residential environments and the quality of the life. Based on this study, it is more effective to plan community facilities to be connected or extended to other external spaces. And tenant satisfaction should be carried out and put into consideration to help determine if community facilities are adequate. Space compositions should be designed to be flexible per social paradigms and customers needs.

  • Purpose: The purpose of this study is to examine the policy implications of establishing a compact city in Seoul, analyzing whether it is an appropriate and efficient eco-friendly housing supply alternative. Research design, data, and methodology: The analysis criteria include efficiency, safety, and comfort, with efficiency encompassing economic, energy, and public transport links' efficiency. Safety and comfort are aspects of eco-friendliness, housing safety, and improvement in living environments. Results: In terms of economic efficiency, compact cities are a less expensive option than purchasing land for housing construction. To increase energy efficiency, we plan to adopt eco-friendly energy sources. Transportation efficiency is high in locations near public transport stations. To enhance safety and comfort, we intend to create large-scale parks and forests in Seoul. To ensure residential safety, measures will be taken to reduce road vibration, vehicle noise, and scattering dust. Conclusions: Selecting an appropriate location that provides convenient public transportation is essential for creating a compact city for housing in a large city. Combining a compact and smart city is necessary, and implementing smart technologies is needed to prevent dust, noise, and vibrations, which are undesirable in a residential environment.

  • Purpose: This study analyzes the factors influencing the housing preferences of elderly individuals when choosing residential areas in Hwaseong, a typical urban-rural complex city. Understanding these preferences is vital for formulating effective housing policies that enhance the quality of older people's life. Research design, data, and methodology: The survey conducted from March 10 to April 10, 2024, targeted 299 pre-retirees aged 50-64 living in Hwaseong. Using ANOVA and logistic regression analysis, the study examined essential factors affecting post-retirement residential decisions. Survey questions addressed essential considerations. Results: The results indicated that suburban housing was the most preferred option among pre-retirees in Hwaseong. The most critical factor that influences the choice of the home is ensuring convenience and relaxed in retirement. Significant differences emerged between housing type preferences, particularly in the importance of public transportation, cultural facilities, and housing prices. Conclusions: The study suggests several policy implications for urban-rural complex cities like Hwaseong. To meet the diverse needs of older people, urban housing should focus on improving accessibility, while rural housing should emphasize enhancing natural environments. Expanding rental housing options for older people and providing financial support for housing prices are recommended to promote housing stability for the aging population.
