The purpose of this study is to evaluate and analyse the characteristics and images of interior environment design in the living rooms, bed rooms and kitchen of the apartment, using the e-model houses of the apartments that will be constructed by 10 construction companies and be occupied after 2006. The 29 defined terms were used in this study to describe the interior image trend. They were systematized by a 5-point scale for the SD evaluation, and were used as a tool to analyse the images. The images were evaluated by methods, such as monitoring the image photos showing the individual rooms in their e-model houses and making their slide film, and reediting them to understand interior atmospheres completely. The image evaluation was performed by the group of 2nd and 3rd year students in the Housing & Interior Design of D University on December 9, 2005, and the data were analysed using SPSS Statistical Program 12.0 for Windows.

Indoor air quality can be affected by indoor sources, ventilation, decay and outdoor levels. Understanding the effectiveness of indoor air quality control depends on knowledge of the characteristics of air pollutants in indoor air, especially their quantities and persistence, and the relevance of indoor sources to these factors. Toluene within new and established houses has been determined and factors significant to its presence have been identified. A total of 30 selected houses in Seoul, Asan and Daegu areas that were constructed within 4 years and over 4 years of construction were measured the concentration of toluene from July to September in 2004. Toluene emission decay of double-exponential model exhibited good fit of $Y=276.37e^{-1.21x}(R^{2}=0.34,\;P=0.06)$ for 2 years and then $Y=51.54e^{-0.11x}(R^{2}=0.40,\;P=0.0)$ from 23 years in new houses. In case of living in new houses, noncarcinogenic health effects of exposure to toluene was 1.38 of hazard quotient (HQ) comparing to toluene reference dose of 0.13 mg/kg-day.

Due to the development of modern society, desire for residence is not merely for the purpose of habitation. It's also used to represent the joy of living, the resident's emotional expressions, and social status. In order to express such desires, one of the most important factors used to portray them visually is the usage of color. When apartments are constructed, model houses are created to show potential tenants a sample house. The color scheme of those sample houses have been changed in accordance to the transition in the eras. Since 2000, construction companies have created their own apartment brand in order to create their own signature image. To achieve this signature image, one can alter the surface level and use other materials, and colors. I have researched the usage of colors out of the above. The criteria that need to be fulfilled to be a subject for my research are in the top 5 construction companies of the year 2010, within the metropolitan area, and open after 2009. As the result, all construction companies used colors Y and YR. An as accent colors on props such furniture and curtains, they used colors P, PB, and R. They were differences in color tones in each construction company and as the square footage increase, they used color contrasts. Hillstate and Raemian used darker shades in the larger houses. But the color tones YR and Y were used in all houses regardless of their size. E-world, Xi, and Prugio showed differences in shade and tone of colors regardless of size but rather depending on the locations of the apartments.

Existing model houses have played an important role in allow the customers to choose apartment. As the information technology has been advanced (e.g. a high-speed internet available in unit), customers' personality and preference to the design of apartment and the purchasing pattern have been changed. Construction firms have introduced VR(Virtual Reality) model house (e.g. Quick Time Virtual Reality) to meet the customers' expectation and need. The reality-based QTVR model house does not provide enough quality to satisfy the customers' expectation. To complement the shortcoming of the QTVR model house, this study presents a web-based cyber model house developed by using Turntool and Javascript. The cyber model house allows to communicate between supplier and customer over the internet.

The remodeling of multi-family houses (MFH) has emerged as a significant issue in the construction industry. Many decision makers struggle with the decision to remodel because of insufficient information including standards or methods for projecting the price of their structure after remodeling. In this context, this research analyzed the change in price of MFHs after remodeling. To achieve this research goal, (i) the price data from 14 groups (i.e., MFH renovation cases and equivalent MFH cases without remodeling) were collected, and (ii) the trend of price variation among each group was analyzed. Finally, this research suggests price variations of each group in terms of three different time points (i.e., before remodeling, after remodeling, and the present), which shows the effects of remodeling on the price of MFHs. This research offers a framework for the development of a model that will predict the price of an MFH after remodeling.

Five zero energy house models developed in Korea for the purpose of the energy performance were compared and analyzed in the study. The standard passive house model applying common technology and efficient energy performance elements was proposed. Standard passive house 5 models have been developed commonly aiming at 100% energy saving, applying high-performance and high-efficiency exterior thermal insulation, using 3 low-e coated window system, and targeting average 0.65 ACH to enhance privacy. Energy recovery ventilators and dry and cold radiant heating floor has been partially applied. Eco-design techniques such as the awning device, heat insulating door, using natural light have been used. Solar and geothermal systems as the application of renewable energy technologies have been commonly applied. And fuel cells were applied to a partial model. The standard model based on common technical elements and average performance of each element and obtained from five model analysis has been proposed in the study.

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.

주택은 여러 가지 요인들의 집합체로 구성되기 때문에 헤도닉 기법을 이용하여 개개요인들의 주택에 내재된 가격을 현시화하고자 하는 연구가 많이 수행되었다. 그러나 이러한 요인들은 서로 상호작용할 수 있으며. 공간적으로 변화할 수 있다는 것을 설명하는데 한계를 가지고 있다. 본 연구는 서울시의 공동주택을 대상으로 주택가격에 영향을 미치는 결정요인들이 공간적으로 다양하게 변화함을 모델링하고자 하였다. 주택가격에 영향을 미치는 인자들간의 상호작용을 밝히기 위해 Casetti의 확장형 회귀분석방법을 사용하였다. 본 연구의 주요결과를 살펴보면 다음과 같다. 초기모델에서는 서울의 공동주택가격을 추정함에 있어 주택규모, 근린환경 특성. 그리고 강남의 재건축아파트 여부가 주요 요인으로 작용하였다. 그러나 이러한 특성들은 도심, 부도심, 강과의 인접성 여부라는 접근성변수에 따라 서로 다르게 상호작용하고 있었다. 주택의 규모가 작은 공동주택은 도심이나 부도심까지의 거리에 따른 주택가격의 변동이 거의 없었으나, 주택의 규모가 큰 공동주택은 부도심에 가깝고, 강에 인접할수록 주택가격은 크게 상승하였다. 반면 부도심에서 거리가 먼 지역에서는 자가주택과 아파트 비율의 변화에 따른 주택가격의 변동이 심하지 않았으나, 부도심에서 가까운 지역에서는 자가주택과 아파트의 비율이 높은 지역에 위치한 공동주택일수록 주택가격은 크게 상승하였다. 모델의 잔차분석에서는 강남, 이촌동, 목동등의 대형평수 아파트들이 과소추정되고 있음을 나타내어 하부주택시장별로 서로 다른 주택가격모형을 적용할 필요성이 있음을 시사하고 있었다.

최근 국내에서 건설되고 있는 주거건물과 주상복합건물은 단일건물보다는 다수의 건물군으로 구성되어 있는 경우가 많다. 단일건물의 경우도 환기 및 채광성을 비롯한 외관상의 문제와 상업성을 고려하여 하층부는 하나의 건물로 이루어지고 중 상층부로 갈수록 두개의 건물로 나누어져 두개의 동이 하나의 건물로 구성되어 있는 건축물이 많이 건설되고 잇는 추세이다. 이와 같이 높고 세장하며 복잡한 건축물은 질량과 감쇠가 낮을 뿐만 아니라 바람에 의한 건물군 사이의 상호작용효과 등에 의해 구조적인 안전성과 사용성은 풍하중에 의해 결정되어진다. 그러나 현재 다수의 건물군으로 이루어진 건축물의 구조설계시 인접한 동사이의 상호작용 효과에 대해 규명되어 있지 못하며 또한 그 상호작용 효과를 예측하기란 어려운 일이다. 따라서 본 연구에서는 현존하거나 현재 건설중에 있는 두 개동을 가진 건축물의 현황을 파악하여 그 패턴을 모델화 한 후, 풍동실험(wind tunnel test)을 통해 두 개의 동 사이의 인동거리에 따른 풍응답 상호작용 효과를 가속도응답을 중심으로 비교분석하였다. 본 연구의 결과로부터 건물군에 대한 풍응답 상호작용효과의 기초적 자료를 제시할 것이며 나아가 좀더 합리적이고 경제적인 구조설계를 위한 자료로 활용될 수 있을 것이다.

This study was performed to evaluate the asbestos exposure levels and to calculate excess lifetime cancer risk (ELCR) for the risk assessment of the asbestos fibers released from asbestos-cement slate roofing (ASR) building. Total number of ASR buildings was into 21,267 in Busan, and 82.03 percent of the buildings was residential houses, and 43.61 percent of the buildings was constructed in 1970s. For this study, ten buildings were selected randomly among the ASR buildings. The range of airborne asbestos concentration in the selected ten ASR buildings was from 0.0016 to 0.0067 f/mL, and the concentration around no-admitted ASR buildings was higher than that around admitted buildings. The ELCR based on US EPA IRIS (integrated risk information system) model is within 3.5E-05 ~ 1.5E-04 levels, and the ELCR of no-admitted ASR buildings was higher than 1.0E-04 (one person per million) level that is considered a more aggressive approach to mitigate risk. These results indicate that the cancer risk from ASR buildings is higher than other buildings, and systematic public management is required for control of no-admitted ASR buildings within near future.
