With a rapidly aging population, the proportion of elderly households with low income has been increasing. Despite the poor housing environment, it is not easy to improve their housing environment due to the high cost of modification. However, as many elderly want to keep living in their current houses, it is urgent to improve their housing environment. The purpose of this study was to develop the guidelines on home modification for low-income elderly. This study set the scope of home modification categories through literature analysis in advance to develop the guidelines. Based on the literature analysis and small group workshops, the primary and secondary guidelines were derived and a total of 169 final guidelines were produced based on the scope of home modification categories. Those guidelines were composed of the categories by space, divided into mandatory and recommended by details. Those guidelines proposed in this study were classified and composed under the objective standards, so that they were systemic and objective based on the verification of experts. They are considered to get closer to the user's demand on the basis of the demand of low income elderly for home modification and the improvement categories under the system to support home modification for low income elderly at home and abroad. In addition, as the standards to apply each guideline, separated into mandatory and recommended, was suggested, those guidelines may help expand the scope of improvement under the economic conditions for home modification.

Housing prices are closely related to various variables that indicate macroeconomic conditions. In this paper, empirical analysis based on data is performed referring to previous studies. Focusing on the policy interest rate among the factors affecting the housing price, the non-linear impulse responses of other variables to the interest rate shock are analyzed. Using the random forest algorithm, the variable importance scores of the macroeconomic variables presented in the previous studies are calculated. After selecting the variables through this process, the impulse responses are calculated using a model that can capture non-linearity. According to the model, the responses of housing prices to the policy rate is only significant when the rate is raised. Especially, the impulse response is amplified when the shock increases due to the non-linear characteristics that can not be captured by the traditional VAR methodology. The analysis results suggest that the interest rate as a policy instrument should be approached from a more cautious perspective.

The purpose of this study was to analyze differences of the indoor environment and student's fatigue response according to ventilation in university lecture hall. The experiments consisted of measuring the indoor environmental parameters and a survey of student's responses. The experiments were in the lecture hall that the actual lecture was conducted in on the $25^{th}$ of May 2009 (not opening windows and door- A) and the $1^{st}$ of June 2009 (opening windows and door- B). The experimental variable was ventilation by opening the windows and door, and the controlled conditions were indoor temperature by air conditioner, volume of the microphone and VTR, lighting conditions and teaching method. The results are as follows: 1) The indoor temperature was maintained in controlling A, B but the $CO_2$ and relative humidity of A (average 3579ppm, 62.6%) was higher than B (average 1697ppm, 48.1%). 2) There were differences in the student's subjective responses and student's fatigue responses between A and B. 3) Therefore, it was found that ventilation by opening the windows and door was a valid way to improve the relative humidity and to reduce $CO_2$ in the lecture hall.

This study aims to examine the existing conditions of elderly housing facilities and to understand the characteristics and types of outdoor living environments utilized by the elderly. To achieve this, this study relied on two methods: a descriptive method of researching publications and related scholastic writings, and an empirical study that included a survey of present conditions and interviews with the elderly and their nursing care providers. Additionally, evaluation of usage patterns and physical traces were carried out in twelve cases. First, the study showed that all of the facilities, which are fixed in particular areas, had difficulty providing spatial diversity that met the needs of residences. This means that these areas lack flexibility. Activity programs were, however, carried out in a lively manner in well-equipped spaces. Second, an evaluation of outdoor living environments showed that basic facilities were more than adequate, in general. Consideration of resident's physical strength and taste, however, was evaluated as low, indicating that facilities and spaces should be considered to reflect the ages, physical capacity, diverse tastes and hobbies of the elderly, as well. Third, examining the usage patterns of outdoor living activities of residents, the purposes of using outdoor spaces of elderly housing facilities were mainly 'to take a walk' and 'to engage in simple physical exercise' and the walkway, simple sports facilities, and building entrances were highly utilized. The importance of outdoor living environments values was a mean of 4.07 and satisfaction was 4.17. This indicates that residents thought that outdoor living environments are very important and currently satisfied with them.

The actual thermal environment and bedclimate on Ondol were investigated by the regions and housing styles in each season. The subject were sixty healthy men and women, 30 of them live in apartment, and 30 of them live in detached house. 20 of them live in Wonju, 20 of them live in Cheongju and 20 of them live in Pusan. The results are as follows: 1) The subject slept in this conditions; 23.1$\pm$2.4$^{\circ}C$ and 38$\pm$8.8% RH in spring, 27.1$\pm$1.5$^{\circ}C$ and 68$\pm$6.4% RH in summer, 27.1$\pm$1.7$^{\circ}C$ and 47$\pm$11.1% RH in autumm, and 24.9$\pm$3.3$^{\circ}C$ and 41$\pm$10.7% R.H in winter The temperatures of the floors were 38.6$\pm$5.$0^{\circ}C$ in the spring, 26.7$\pm$1.9$^{\circ}C$ in the summer, 29.4$\pm$4.7$^{\circ}C$ in the autumm, and 30.0$\pm$5.8$^{\circ}C$ in the winter. 2) Each thickness of the quilts was thinner in the summer than in any other season, but the differences in the thickness of each mattress was not significant by the seasons. 3) The differences of the bedclimate and the clothing microclimate were significant by the regions and housing in each seasons. The inside of temperature and humidity of sleepwrar were highest in summer. The bedclimate showed high correlation with the clothing microclimate. 4) The differences in the sensation which the subjects felt about temperature and comfort of the bedroom conditions were not significant by the seasons, regions, or housing styles. But the subjects felt more humid in the summer and spring than in the autumm and winter.

The purpose of this study is to the examine sense of community of the residents living in an apartment complex and the relevant features of the community facilities provided in the complex, such as actual facility conditions, needs and satisfaction. Five apartment complexes constructed after 2000, each containing more than 500 units were selected for this case study. The actual conditions of the community facilities regulated by current laws were inspected. Those facilities were the administration office, gym, multi-purpose room, sauna and shower room, indoor and outdoor children's play-grounds, study room, etc. 37 residents were interviewed to access their needs and level of and satisfaction with the provided community facilities. Based on the results, we suggest that basic community facilities for exercise, child care and children's recresion need to be provided regardless of the apartment complex size. The respondents revealed a medium level of sense of community, which was psychologically limited to their apartment complex. Indoor and outdoor children's play-grounds had great potential to encourage social interaction between the residents. The findings point to a need for improvement of the current relevant regulations with the perspectives of flexibility and application in terms of space size and mandatory types.

This study aims to suggest the direction of urban planning for coping with climate change focusing on urban metabolism. The study consists of two main parts: literature review and case study. The cases are selected for mixed-use housing estate in Europe, which established the plans for energy saving and efficient use of resources and waste. The case study was carried out in accordance with the framework, which had four aspects that are 'to minimize energy input,' 'to use renewable energy sources,' 'to recycle waste,' and 'to reuse natural resources.' As a result, in all the cases, analysis showed that the circular metabolism system was built for energy, waste and water resources and that the plan satisfying all the aspects of the framework was established. Moreover, main planning elements are different reflecting resource conditions for each case. In conclusion, in order to achieve urban metabolism, it will be necessary to analyze various conditions including the surrounding environment of the region and to introduce planning elements that can maximize the regional potential.

The modular apartment has been completed for the first time in Korea through the national research and development (R&D) project in December 2017, and 30 households moved in. Although conditions such as technicality and constructability have to be satisfied to adopt and spread the modular apartments in the future, economic feasibility is the most important factor among the conditions. The economic feasibility of modular apartments can be compared with that of existing reinforced concrete (RC) structure apartments. It is highly important to reduce the construction cost through standardization above all. The standardization refers to establishment of national design standards and principles, and it is important for manufacturers and building companies to comply with those standards and principles. The modular construction (MC) skill in Korea is at an early adoption stage and the MC market is not widely expanded yet. Thus, the application of the MC design, which is the basis of the standardization, has not been widely accepted. However, related R&D projects are now performing mainly by the Ministry of Land, Infrastructure, and Transport to promote modular apartments in recent years and the design standardization standard (draft) is now prepared to be notified as a result of the steady research. Furthermore, pilot complexes for demonstration purpose are under construction, starting from public rental apartments. Thus, MC method-applied public rental houses will be spread in near future. This study aims to investigate the current design status in the Ga-Yang Housing as a pilot modular complex to produce and supply more economical and efficient modular houses, and analyze the problems by comparing the design standardization standards with pre-notified design standardization standards and summarize the modifications between them thereby presenting foundational data for establishment of the design standardization in the modular business industry.
