The statistical analyzing of environmental-friendly planning elements is getting important because it is getting concerned with the change of residential types and environmental friendly housing. However, in terms of the high-rise residential complex, paper about green building rating system and research about residential satisfaction to residents are lack. Therefore, this paper is analyzing of impotentness and satisfaction about housing subdivision, inside of building, facility, and maintenance. In addition, residential satisfaction(satisfaction, loyalty, preference) and impact relationship of environmental-friendly planning elements are analyzed by PLS structural equation. To sum up, first, improving of green building rating system in housing subdivision is impacted on loyalty if satisfaction was fulfilled. Second, increasing of environmental-friendly planning elements in inside of building is impacted on loyalty if both satisfaction and preference were fulfilled. Third, providing of green building rating system in facility and maintenance is analyzed as preference, but satisfaction hypotheses is not valued.

Many buildings have been bolt in Korea. Because blasting operations and more efficient to make excavate rock than other methods, it's more extensively used for new construction, enlargement of buildings, subway work, etc. However, blasting vibrations and sound often create pollution. A study, 'The place of gathering earth and sand to construct a building site in Yangsan', has been done in Gyo-dong, in Yangsan. There are two high-rise apartment and buildings, beside a construction site. The blasting vibrations and sound were monitored on the 1st, 4th floors in building(4th floor), and the results of the analysis are as follows: The blasting vibrations decreased being transmited from 1st floor to 4th floor.

This study introduces the development of a precast concrete double-wall, applicable to basement construction in apartment buildings. Unlike traditional precast concrete double walls, the developed double-wall doesn't require specialized manufacturing equipment such as a lathe. The constructability of these advanced technologies was validated through a full-scale mock-up test using the precast concrete double wall. The test specimens were constructed to represent a structural wall with a thickness of 250mm. It was observed that the quality of the in-situ concrete, filled between two single panels of 110mm thickness each, was excellent. The construction efficiency of the developed double-wall system for basement construction in an apartment building was also examined. Expert interviews about installation times of precast concrete elements were conducted to evaluate the speed of the basement floor's installation. The results showed that installation of precast concrete elements, including the proposed double walls, could be completed within 20 to 29 days for a basement in an apartment building. This indicates a three-fold increase in construction efficiency compared to traditional methods relying on in-situ casting.

The purpose of this study was to promote the utilization of wind velocity of kitchen and bathroom exhaust ducts for wind power generation in high-rise apartments. The research content can be summarized as follows: 1) Nine high-rise apartments were examined for the installation of kitchen and bathroom exhaust ducts located in the pipe shaft (PS) section. After selecting simulation candidates, a simulation was performed with the STAR-CCM+ Ver 5.06 program. 2) Of nine high-rise apartments, seven had kitchen and bathroom exhaust ducts, whose cross section was in the range of $0.16m^2{\sim}0.4m^2$. The area ratio between the exhaust ducts and PS section (cross section of exhaust duct/area of PS section ${\times}$ 100) was on average 3.2%. 3) The simulation results were analyzed. As a result, the smaller cross section kitchen and bathroom exhaust ducts had, the more advantages there were for increasing exhaust wind velocity. If an out air inlet duct is installed to the old kitchen and bathroom exhaust ducts, it will increase exhaust wind velocity by 3.01~3.98m/s and contribute to the proper wind velocity level (3.0m/s). 4) When the simultaneous usage rate between the kitchen and bathroom exhaust fan increased from 20% to 60%, exhaust wind velocity increased. The "entire house holds" condition for exhaust fan operation provided more even exhaust wind velocity than the "some house holds" condition. 5) Exhaust wind velocity increased in the order of amplified (T-3), induced (T-2) and vertical (T-1) top of kitchen and bathroom exhaust ducts. Of them, the amplified type (T-3) was under the least influence of external wind velocity and thus the most proper for kitchen and bathroom exhaust duct tops.

기후변화가 현실화되면서 수자원평가 (Water Resources Assessment)에 대한 관심과 중요성이 높아지고 있다. 본 연구에서는 '주민공감 문제기획리빙랩' 대상지인 순천은 동천을 중심으로 홍수량을 정량적으로 분석하였다. 순천시의 가장 시급한 사안 중 하나인 범람 및 침수 문제로, 최근 3년(2018~2020)간의 집중호우로 인한 내수배제로 주택 및 도로침수, 산사태 등의 피해를 겪었다. 시기마다 고질적으로 반복되는 동천 인근 지역의 침수문제를 사전에 예방하고 피해의 빈도나 규모를 줄이기 위하여 분석을 수행하였다. 이에 본 연구에서는 환경부의 지원을 받아 한강홍수통제소와 한국건설기술연구원이 공동으로 개발한 동적수자원평가모형(DWAT, Dynamic Water Resources Assessment Tool)을 이용하여 정량적으로 홍수량 산정을 하고자 한다. 본 모형은 전 세계가 무료로 이용할 수 있는 수자원평가도구로 사용자의 편의를 위해 GIS전처리 기능을 포함하고 있어, 자동으로 유역 매개변수 및 면적 평균강우량을 Thiessen method를 사용하여 산정할 수 있다. 또한, 물의 순환과정을 투수 및 불투수지역으로 구분되며, 투수지역은 1개의 토양층과 1개의 불압대수층으로 구성되고, 유출기여역과 함양역으로 유역을 분할하여 적용할 수 있으며, 대수층을 통하여 지하수의 흐름을 산정할 수 있다. 기상청에서 제공하는 기상자료를 분석하여 과거 관측 강우사상 3개를 선정하여 검·보정을 수행하였으며, 그 결과 모형 효율계수(Nash-Sutcliffe efficiency) 및 결정계수(Coefficient of Determination)가 0.78~0.94, 0.82~0.94로 우수한 모의 결과를 산정할 수 있었다. 빈도별 확률강우량을 Huff 4분위법을 사용하여 확률홍수량을 산정하였다. 미래 홍수량 증감량 산정을 위하여 RCP(Representative Concentration Pathways) 기후변화 시나리오를 사용하였다. 관측값과 모의값의 누적확률분포 이용하여 모의값의 확률분포를 관측값의 확률분포에 사상시키는 방법인 분위사상법(Quantile Mapping)을 사용하여 시나리오자료를 보정하였다. 본 연구에서 산정한 홍수량을 바탕으로 침수피해를 막기 위한 구조적 및 비구조적 방안을 위한 기초자료로 사용될 것으로 판단된다.

Apartment housing is a widely-spread type in Korean housing market. Nevertheless, it has caused serious problems such as traditional community corruption, unsafe structure, defects and litigation from noise. Noise, especially in concrete structure for apartment housing, is hardly controlled in proper to prevent sound transmission between upper and lower families with existing system. In foreign countries, there are floating floor system to enhance the noise control performance in multi-family housing. This study is to examine the impact sound insulation performance of floors according to the different P'yong and Layers by field measurement in highrise building.

As the society is industrialization and urbanization, the increase in density of urban population brought about the rise of the land value and the shortage of the land for housing, as a result urban housing shortage was on the rise in a new social problem. According to this high-rise apartment buildings is under construction, but that is required habitation and safety, especially security for fire safety, because it is various age group residents in for 24 hours. Consequently this study aims to present problems and countermeasures against fire safety of high-rise apartment buildings and to construct a residential space to minimize human life and property damage caused by a fire.

This study aims to offer basic data for development of the three generations sharing house plan, through finding out the relationship between family characteristics and the housing needs of the middle aged living in the middle and small cities. The 1029 questionnaires were used for this study, and data were analysed by canonical correlation analysis, factor analysis and multiple regression. The results are as follows. Their family characteristics influence housing needs for the three generations sharing house. Especially groups of female, neuclear family, family of higher S.E.S., less number of children. family living in the apartment houses and owner occupied house prefer more privacy between generations in the three generations sharing house.
