The evaluation of the quality of residential environment may be different according to the experts' characteristics. This study aimed at estimating the relative weights of the constituents of a residential environment by AHP(Analytic Hierarchy Process) through experts' evaluation. The respondent group was composed of 72 experts in the fields of architectural design, housing design, urban design, and urban planning. The findings are as follows(:) 1) the relative weights of residential constituents were different between detailed fields ; 2) the relative weights of residential constituents were not different according to institute in which experts are engaged ; and 3) for the practical application of estimation results of the relative weights, the relation between residential performance constituents and physical design elements should be considered in future.

이 연구의 목적은 당사에서 제작한 멤브레인형 $130,000M^3$와 $135,000M^3$ LNG 운반선의 진동특성을 파악하고, 거주구역의 진동수준을 예측하기 위함이다. 우선 공진 회피의 관점에서 최적의 프로펠러를 선택하기 위해 간단한 계산을 수행한 후, 주변 해수를 고려한 선박 전체를 모델링하여 3차원 유한요소해석을 수행한다. 이 계산은 보다 정확한 고유진동수를 결정하고, 프로펠러 기진의 주파수 범위에서 관련된 모드 형상을 결정하며, 선박 거주구에서 기대되는 진동수준은 잘 예측할 수 있다. 다음으로 선박이 진수되고 전체구조가 조립된 후 안벽에서 불평형 가진기를 이용해 가진기테스트를 실시하고, 해상시운전 중에도 동일한 방법으로 테스트를 실시한다. 시험은 고유진동수의 항으로 선박의 실제진동응답과 계산결과와의 좋은 비교를 가능하게 한다. 추가적으로 실제 엔진을 구동해 RPM을 최저에서 최고까지 천천히 변경하면서 실제 운항 중 진동응답을 계측함으로서 고유진동수를 예측하여 해석결과 및 가진기 시험결과와 비교한다.

디지털 삶에서 인간들은 더 이상 보호막으로써의 건축 환경이 아닌 함께 상호작용 할 수 있는 감성반응 환경을 요구한다. 즉, 실내 공간은 사람들의 요구를 충족시키거나 사람들의 기분을 만족시키기 위해 건물이 마치 살아 있는 유기체처럼 쉬지 않고 변하는 공간이다. 그러나 건축공간의 물리적 특성의 한계에서 유동적인 감성반응 환경의 요구를 충족시키는 데에는 많은 한계점이 따른다. 그래서, 본 연구에서는 이러한 한계점을 극복하기 위해 디지털 환경을 이용한 가상공간에서 실행하였다. 이는 실제공간에서의 시행착오를 줄일 수 있을 뿐만 아니라 빠른 시간 내에 인간의 반응을 연구할 수 있다. 특히, 본 연구에서는 감성반응의 실내배색에 의해 실내공간에서의 디지털 벽면의 디자인을 가상공간에서 개발하여 거주자의 감성 반응을 평가하는 것을 연구 목적으로 두었다. 이와 같은 거주자의 감성반응형 환경 디자인은 미래의 디자인의 패러다임이 될 것이다.

The purpose of this research is to suggest design direction about common space of small sized residential units for elderly housing in order to construct desirable residential environment. This research examines spatial composition and the residents' behaviors in three different types of residential units at intervals of five minutes from 9:00 a.m. to 19:00 p.m.; and analyzes the characteristics of spatial use. The following is the result. The using rate of common space is influenced by the atmosphere of residential units more than healthy condition of the elderly; furthermore, the frequency of usage is also increasing highly as mush as forming the lively atmosphere. In order to form the animated residential environment, it is necessary to provide to various activities, such as cooking, eating, watching TV, leisure, hobby, rest, etc; and the space must plan encouraging relationship with other people. Moreover, it is required to consider to each of personal characteristics ingeniously, and manage to programs extending their durability in common space of elderly housing.

With population growth and quality of life improvement, household energy use also has increased. Under this circumstances, consumers are increasingly required to seek for efficient ways of energy saving. However, precedent studies have largely overlooked energy consumers' consumption behavior, and particularly little research has been conducted on energy consumption or saving patterns of residents living in apartments, which account for over 50% of the Korean housing market. Therefore, this study examined apartment residents' energy use behavior according to apartment residents' characteristics in order to efficient energy use and management. To this examination, survey was conducted of housewives living in apartments in Busan, and 403 data were analyzed by the SPSS WIN 12.0 program. With respect to their energy behavior according to characteristics of subjects, it was different depending on income, housing size, age, the length of residence, and the education standard. When higher income group and larger housing size group, residents were not doing 'passive saving' and 'comfort oriented.' When younger, they were 'comfort oriented.' When well-educated, they were 'comfort oriented.' Also, with regard to the length of residence, significant difference was found. The results of this study can be utilized as effective guidelines in efficient management, policy making, and education method reflecting energy use behavior of energy users.

It has been recognized that the evacuation planning is very important for effective evacuation of occupants on fire event. However the present evacuation planning and regulation for fire safety usually tend to meet the minimum requirements based on the existing laws and regulations. The ultimate goal of the evacuation planning is evacuate occupants rapidly from building fires to the safe areas. In this study, First, analyzed occupants load density and occupants characteristics in high-rise apartment buildings, Second, A evacuation safety performance of high-rise apartment buildings was analyzed with various typical floor plans. The purpose of this study is to figure out the evacuation characteristics in high-rise apartment buildings and improve countermeasure through comparative study on the Evacuation regulation and floor plans for High-rise Apartment buildings.

The main objectives of this study were to investigate the characteristics of clothing buying behavior under the refund policy of stores (CCBBURPS) and the influence variables on CCBBURPS and to build the model of CCBBURPS. Additionally frequency and reasons for refund were researched. The interviews with 26 subjects the reviews of previous studies and the empirical investigation were processed for the study. The data was collected from 163 Korean females living in U.S. and analyzed by frequency mean factor analysis {{{{ chi ^2 }}-test, t-test and regression. The following results were found : the easyness of decision making (EDM) the loyalty of refund policy store (LRPS) and the increase of buying (IB) were found as the characteristics of clothing buying behaviors under the refund policy. EDM, LRPS and IB were influenced by clothing attitudes-shopping involvement and perceived buying risk-. The frequency of refund with 10 purchases was usually 0~1 times(38.7%) or 1~2 times (38.7%) The reasons for refund were : size unflattering appearance design com\ulcorner. The model of CCBBURPS was built based on the above findings(fig. 1)

기상폭발은 가연성물질이나 산화제의 성질 및 공간의 상태에 크게 의존하며, 밀폐공간에서 일어날 경우에는 그 공간을 구성하고 있는 벽면의 강도 둥에 의해 폭발현상이 달라진다. 밀폐공간의 가로, 세로, 높이 중 임의의 두 방향 치수비가 1보다 극단적으로 다르지 않은 거주공간의 경우 공간내의 가연성 혼합기의 농도분포, 공간을 구성하고 있는 벽면 가운데 약한 부분의 강도 및 넓이, 개방되고 있는 창등의 개구부의 넓이등의 상태가 폭발 특성에 대한 변수가 된다. (중략)

국내의 건축물의 화재안전성 평가는 화재안전성을 고려한 공간구성, 연기의 유동, 거주자의 피난계획 및 피난성능평가, 건축물 내부에 설치된 방화설비계통의 화재안전성능평가 등을 연구하여 왔다. 그런데 이들 연구의 대부분은 건축물의 공간적 특성분석과 주거여건 등을 고려한 기초자료의 파악 및 분석 등을 국내의 여건과는 상이한 국외의 자료를 근거로 하거나 2차원적인 해석 및 평가에 그치고 있는 경향이 있다. (중략)
