Using multivariate GARCH model, we estimate the relationship between the housing sale prices and lease prices in the Korean housing market. In the analysis of relationship between the rate of changes in sale and lease prices, the correlation coefficient of the apartment and detached house is higher than that of the townhouse. By housing type, the correlation coefficient between detached house and townhouse is higher than between apartment and detached house or apartment and townhouse. By housing size, there are no significant different results between the sales price and the rental price. The correlation coefficient between medium and small size is the highest in the apartment housing market, whereas the correlation coefficient between large and medium size is the highest in the detached housing market, resulting from the fact that people may be more interested in medium- and small-sized apartment and large- and medium-sized detached house. In the detached housing market, the correlation coefficient between large-medium size and medium-small size in the rental price is higher than that of sales price. This result implies that the process of the decision making between purchasing and leasing a house might be different.

The Colonial House is one of the most popular styles in America. The purpose of this study is to closely examine this style based on interior features classified by patterns and elements during America's colonial period. Results of this study show that the interior style of the Colonial House was, at first, similar to Europe style. It was then integrated into the Georgian style of England and affected by Palladio as time passed. The interior style of the American Colonial House was based on rationality and practicality in concern with American weather and regions rather than imitation. The side of the roof was clapboard and the windows arranged with symmetry and rules around the entrance hall. It was generally Palladian style and was decorated with classical details. Timber frame of the interior was based on log cabins that appeared early in the American immigration. Furniture styles such as Jacobian, Queen Ann and Chippendale were matched with unique wood-oriented details and folkways like Chest, Rush Chair and Windsor Chair The house was also decorated with pictures, mirrors and ornaments, etc.

Recently, It has been much interest in modular housing construction. so, The purpose of this study was to investigate the characteristics of the indoor air quality in modular mock-up housing. We measured indoor air quality(formaldehyde, benzene, toluene, ethylbenzene, xylene, styrene) of two modular mock-up units that built-in furniture is installed and uninstalled. As a result, the pollutants of built-in furniture installed unit were emitted more than built-in furniture uninstalled unit. But after bake-out and ventilation, emission concentrations of two modular mock-up units were similar and were below Indoor Air Quality recommendation standards. Built-in furniture is likely to affect the emission concentration of toluene

Paradigm for supporting housing for low-middle income class has been changing from public rental housing to Housing Voucher. Housing Voucher started first in Seoul since 2010, and it has been expended to other areas in 2014. Given the dearth of previous research data, this study aims to analyze options determinants that the beneficiaries could consider in choosing their residential area. In this study, the researcher used for the research methods, a quantitative analysis by Geographically Weighted Regression (GWR) and Ordinary Least Square (OLS) has been conducted. As a result, the accessibility to social welfare centers, public transportation and job opportunities emerged main factors to for the Housing Voucher recipients in Seoul to choose their residential area. This is different results from previous research, which has two implications. First, reexamination of Housing Voucher is necessary. Second, Housing Voucher beneficiaries should include not only the housing but also support for family and welfare system access.

Public rental housing is constructed, owned, and managed by the public sector. The public institution for the public rental housing controls the whole building life cycle from the construction to the demolition. The construction company for the house built for sale is strongly interested in the cost for the initial investment, while the public institution is more focused on the maintenance cost for the preservation of the buildings Nevertheless, the maintenance cost of the public rental housing has been only managed as the accounting factor without the systemic research and analysis on the actual condition. This paper shows how expenses are related to the degree of obsolescence and presents the differences of the maintenance costs by the housing area and expenditure trends (vs time) of the maintenance costs, through analyzing time series data of public rental housing maintenance cost. Further, this paper helps understanding the causes of the differences of the maintenance costs by housing areas and characteristics of the expenditure trends. After all, this paper contributes to the improvement of the reliability and the practicality for the Life Cycle Cost modeling and the maintenance cost estimating.

To research about the fire spread in Korean apartment house, a full-scale fire test in a four-story apartment was executed. The fire started at the third floor, and originated from overheated cooking oil in the kitchen. The apartment included all combustibles in general house. Through measuring temperature, measuring the concentration of oxygen and observing, we investigated the fire spread inside the apartment house. As a result, we got the data of the time needed for the initiation of fire, the time for fire to spread into each area in the house, and the time required until flash-over was seen. Also we grasped the understanding of the fire spread to the upper floor.

In order to investigate the degree of household dust contamination, 48 samples of household dust (24 from urban area and 24 from rural area) in Daegu city were collected in vacuum cleaner during January to February 2009. Samples were sieved below 100 ${\mu}m$, and 14 elements (Al, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, V, Zn) were analyzed using ICP after acid extraction. Results obtained from the source assessment of trace elements using enrichment factor showed that Ca, Fe, K, Mg, Mn, Na, and V were influenced by natural sources such as weathered rock and resuspended soil, while Cd, Cr, Cu, Ni, Pb and Zn were influenced by anthropogenic sources such as fuel combustion and waste incineration. Concentrations were remarkably higher in components from natural sources than in components from urban anthropogenic sources. Household dust in urban area was more affected by anthropogenic sources compared with that of rural area. Pollution index of heavy metals revealed that urban area was 1.8 times more contaminated with heavy metal components than rural area. The correlation analysis among trace elements indicated that components were correlated with natural sources-natural sources (Al-Mg, Al-Mn, Fe-Mn) and natural sources-anthropogenic sources (Al-V, Fe-Cr, V-Mn) in both urban area and rural area. Trace element components of rural area were more correlated than those of urban area. Houses that use oil for heating fuel had relatively higher contents of heavy metals rather than those using gas or electricity for heating fuel. Houses with children also had higher contents of heavy metals. In addition, the age of houses was found to influence the heavy metal levels in household dusts, with older houses (>10years) having higher concentrations than newer houses (<10years) and houses located near the major road (<10 m) were found to have relatively higher heavy metal levels in household dust.

This study aimed to empirically analyze the factors that influence newlyweds' housing tenure. For this, a questionnaire survey was conducted among newlyweds living nationwide who had been married for 5 years or less and were under the age of 40. The results of the survey were empirically analyzed by applying various variables. With regard to parental financial support among the factors influencing newlyweds' housing tenure, the analysis results showed that the probability of owner occupancy was high among the households with parental financial support than among those with none, and the larger the size of the parental financial support was, the higher the probability that the newlyweds owned the house they were occupying. As for the housing loan variable, it was found that the probability of owner occupancy was high among the newlyweds with a housing loan than among those with none, and the larger the amount of the newlyweds' housing loan was, the higher the probability that they owned the house they were occupying. As opposed to what is generally recognized, however, the survey showed that the higher the ratio of dual earners is, the lower the owner occupancy probability due to the probability of job transition, etc. In addition, it was found that the probability of owner occupancy for the newlyweds living in Seoul was lower than that for the newlyweds living in other regions in South Korea. Accordingly, this study showed that appropriate levels of parental economic indicators should also be reflected in the stable housing support and loan policies for newlyweds in the context that the succession to their parents' fortunes is generalized.
