After 1980's, as economy was rapidly grown and real estate market was active, greatly increased in population has been supplied to the city. Accordingly, national apartment house market is located in the form of Urban Housing Culture. However, as time goes by the apartment houses where the supply of mass became superannuated and residential environment became poor. So, the environment of old apartment houses has been changed to improve with reconstruction. It has been changed in response to the demands of the times. It is one of essential part in a remodeling field for the future although it has some problems in the way that uses existing buildings.

Recently, the number of elderly living alone suffering from loneliness and depression is also increasing significantly due to the rapid aging of the population and nuclear families. In this paper, we propose a smart aging system that increases life satisfaction by providing the elderly with the optimal service tailored to the elderly with the help of IT according to their residential environment and health status. It is possible to provide an advanced customized support system for the elderly by fully utilizing IoT, AI, and Metaverse techniques not only for the elderly who want to live an active life in society but also for the elderly who need care in a nursing hospital. The proposed system provides human satisfaction by providing social connection in real space and virtual space in accordance with the residential environment and health status to the elderly suffering from loneliness in hospital (hospital care) facilities and at home. This paper proposes a new path for future-oriented welfare policy for the elderly by providing a user-customized smart aging system by combining AI and Metaverse technology with a rapidly changing social environment.

Recently, the real estate is of high interest. This is because real estate, which was considered only a residential environment in the past, is recognized as a stable investment target due to the ever-growing demand on it. In particular, in the case of the domestic market, despite the decrease in the number of people, the number of single-person households and the influx of people to large cities are accelerating, and real estate prices are rising sharply around the metropolitan area. Therefore, accurately predicting the prospects of the future real estate market becomes a very important issue not only for individual asset management but also for government policy establishment. In this paper, we developed a program to predict future real estate market prices by learning past real estate sales data using machine learning techniques. The data on the market price of real estate provided by the Korea Appraisal Board and the Ministry of Land, Infrastructure and Transport were used, and the average sales price forecast for 2022 by region is presented. The developed program is publicly available so that it could be used in various forms.

The purpose of this study was to analyze the problems of housing education in Home Economics and then to present some suggestion for improving the housing education in the middle school and to analyze the problems of housing edcation that was investigated on the recognition and application in real life of housing area subject to male/female students in the middle school. The respondents were 600 boys and girls of middle school. Statistical methods adopted for data analysis were Frequency, Chi-square, t-test, F-test. The major findings were follows: 1. Many students(67.2%) responded that housing of home economics was wholly helpful in the actual life. 2. Many students recognized the necessity for the housing education. They particularly recognized the need about the knowlidge of sanitation and facilities of housing. 3. The degree to which housing education applied in the real life was lower than that to which it was needed. 4. There was a tendency that the more students realized the usefulness of housing education, the more positively they applied it in the real life. 5. The contents that students preferred to be additionally included in housing education were improvement of residential environment, solutions to housing environmental deterioration and pollution, future housing, and housing for the elderly.

The purpose of this study was to find the characteristics of the housing needs of apartment purchasers in derision-making steps. The survey was took place from June to July, 2003 in the Daegu area. The data were collected from 1,187 married women using questionnaires and reponses were analyzed by SPSS Window Program. The results were as follows : 1. In the phase when housing problems are recognized the motives for moving were related to the floor space of the housing unit and the residential environment. 2. In the phase of acquiring information on apartments, the basis of the informations was mostly collected through conversations at model houses, from relatives, experts and real estate agents. 3. In the phase of considering alternative plans for apartment purchases, the factors considered were convenient interior space composition and educational environment for children. 4. In the phase of apartment purchase, the important factors was input from relatives and experts. 5. In the phase of post-purchase evaluation most discontent was related to privacy issues, interior space composition, and educational environment for children.

Modeling the effects of high-rise buildings on thermo-dynamic conditions and meteorological fields over a coastal urban area was conducted using the modified meso-urban meteorological model (Urbanized MM5; uMM5) with the urban canopy parameterization (UCP) and the high-resolution inputs (urban morphology, land-use/land-cover sub-grid distribution, and high-quality digital elevation model data sets). Sensitivity simulations was performed during a typical sea-breeze episode (4~8 August 2006). Comparison between simulations with real urban morphology and changed urban morphology (i.e. high-rise buildings to low residential houses) showed that high-rise buildings could play an important role in urban heat island and land-sea breeze circulation. The major changes in urban meteorologic conditions are followings: significant increase in daytime temperature nearly by $1.0^{\circ}C$ due to sensible heat flux emitted from high density residential houses, decrease in nighttime temperature nearly by $1.0^{\circ}C$ because of the reduction in the storage heat flux emitted from high-rise buildings, and large increase in wind speed (maximum 2 m $s^{-1}$) during the daytime due to lessen drag-force or increased gradient temperature over coastal area.

The aims of this study were to grasp the real condition state and clarify the characteristics and influence of pollutants on the indoor air pollution in occupied apartment units. The research method was to measure the pollution levels of indoor air pollution, and investigate characteristics of the pollutants such as the outdoor environment, elapsed time after construction, finished materials, temperature, relative humidity, space extension, purchase with furniture and electric appliances, built-in closets, and method for cleaning the air. And these were made a comparition between industrial and residential area. The VOCs and formaldehyde concentration in indoor air were measured the 6 household in residental area and 5 household in industrial area. In conclusion, the concentration such as benzene, ethylbenzene, toluene, xylene, styrene showed the pollution state within permissible levels, however formaldehyde concentration has need a lot of attention as ever. And it turned out that the influence with reference to emission from building materials on indoor air pollution lessened under 18 months elapsed time after construction.

With the rate of spread of motors rapidly increased, but parking difficulties in an apartment complex was aggravated due to an insufficient parking lot. Visual interference on residential environment, various kinds of pollution and noise, decrease of open space in an apartment complex are also causes of parking difficulties. Therefore, this study is to suggest a theory of desirable direction for planning of the parking space by studying psychological characteristics of users' behaviors by the type of the circulation of motors and pedestrians. Consideration on the present situation, real conditions of underground parking space and the consciousness and parking habit of residents, the most important problem is required in this study.
