From the ancient to contemporary architecture, the light has been an important theme determining the characteristics of interior space. Especially in the religious space, the light was manipulated to express the worship for a god more than a physical element of the nature. It implied that human's space perception through the light was considered prior to the space itself. The perceptual experience in space was primarily elicited by the light with other factors, such as water, texture, and sound which temporarily renewed and updated the information of space. In this study, we critically analyzed the effects of the light which enhanced human's perceptual experience in the religious space in the view of Merleau Ponty's phenomenological philosophy. We suggested that the light was one of the mos4 effective factors to express the characteristics of the religious space with respect to the Phenomenological Light which contributed to the continuity of time, expansion and direction of space, immaterialzation, and perceptual illusion.

In this study, in order to find out relationship of green space distribution and lower air temperature effect, observed air temperature distribution in and out green space in the cloudy. On basis of the result, we are analyzed relationship of air temperature distribution in and out green space, of green space distribution and air temperature of, lower air temperature effect and the urban in between the green space by using regression analysis. According to the result, the higher temperature zone formed around urban, and the lower temperature zone was similar to shape of green space. In case of the green space, higher temperature zone is formed around paved surface and barren ground, lower temperature zone is done forest and water area. To compare air temperature of windward and leeward around green space, the windward formed the lower temperature zone and although the wind direction is not the leeward to the green space, air temperature formed lower temperature zone to the urban in between the green space.

본 논문에서는 기하학적 비선형 후좌굴 유한요소 해석을 통하여 얇은 멤브레인에서 주름 발생이 컷의 진전방향에 미치는 영향을 연구하였다. 해석에는 양단에 인장을 받고 있고 중앙에 기울어진 컷을 가진 직사각형 멤브레인을 고려하였다. 주름이 발생한 경우와 주름이 발생하지 않은 경우에 대해 각각 해석을 수행하여 컷의 진전각도 및 $J$-적분값을 비교하였다. 컷의 진전각도는 에너지 방출률이 최대인 방향, $K_{II}$의 값이 0이 되는 방향을 구하는 방법 및 접선응력이 최대인 방향을 구하는 방법을 사용하여 계산하였다. 또한 다양한 컷의 초기방향각을 고려하여 각도에 따른 주름의 영향을 조사하였으며 가상의 미소크기의 컷을 반복적으로 진전시켜 컷이 전파되는 경향도 알아보았다.

인간-컴퓨터 상호 작용은 인간공학과 정보기술을 융합하여 인간과 컴퓨터와의 상호 작용 기술을 연구하는 학문이고, 그 중에서도 지능형 공간은 정보화 사회에서 소외될 수 있는 장애인에게 더욱 효과적인 사용 환경을 제공할 수 있는 중요한 연구 분야이다. 장애인을 위한 지능형 공간에서의 정보 지원 방법은 장애 유형에 따라 달라지는데, 본 논문은 정보 지원 대상을 청각 장애인으로 한정한다. 청각 장애인에게 직접 접촉을 통해 정보 제공 위치를 인지시키는 방법을 제외하면, 시선이 향하고 있는 곳에 정보를 표시하는 것이 가장 효율적인 정보 제공 방법이기 때문에, 시선 방향 검출 방법은 필수적이다. 우리는 이처럼 청각 장애인에게 실내 생활 지원 서비스를 제공하기 위해 반드시 필요한 시선 방향 검출 방법을 제안한다. 제안된 방법은 다시점 영상(Multi-view Camera Image) 내에서 검출된 사용자 영역 정보를 이용하여, 시점 별 수평/수직 방향 시선각 후보를 생성하고 후보 간의 크기 비교를 통해 사용자의 시선 방향을 계산한다. 실험 결과에서, 제안된 방법은 높은 시선 방향 검출 성능을 보이며, 장애인을 위한 시나리오를 수행할 수 있는 가능성을 보였다.

In case of commercial area of underground commercial area that occupy large amount of space among underground space, the lighting plays a very important role in terms of user's psychological and physiological side. The purpose of this research is to suggest the direction of lighting design of underground commercial area for revitalization of urban function. Spacial scope of this research were adjusted as 8 underground commercial area in Seoul. Scope of content of this research is about lighting plan of underground commercial area. Research methods are as follows: First, we identified the psychological and physiological problem of the underground space which appears in preceding research and the literature. In order to make the design element which is necessary to an underground space it executed this research method. By this research method we made the design element which is necessary to an underground space. Second, Through site visits, illumination level and lighting plans were studied by each category. Third, we presented the direction of illumination plan of each space in underground commercial area We could conclude a conclusion as following through this research. First, lighting plan of underground commercial area should solve user's psychological, physiological problems and should take advantage of the traits of each space. Second, the usage of space of underground commercial area changes as time pass, a lighting plan is needed in order to cope with this. Third, a lighting plan is needed for user's rest within underground commercial area. Fourth, detailed lighting plan is needed for space users of underground commercial area.

This study aims to suggest a Biophilic classroom design of high school to obtain attention restoration for students. The learning space for youth in the modern society is composed of dry artificial structures. This space is considered to be a space that can not relieve stress caused by learning. "The Attention Restoration Theory" is divided into "Directed Attention" of humans, which is the cause of fatigue and stress, and "Involuntary Attention" as a solution to it. "Involuntary Attention" takes place in a rest state and helps the brain recover when exposed to nature. And the core of "Biophilic-Design Theory" is that humans can recover physical and mental conditions when exposed to nature. The purpose of this study is to apply "The Biophilic-Design Theory" that emphasizes the importance of exposure to nature to the educational space and plan the space where the 'Attention Restoration' can be achieved. The research method is as follows. First, we review previous studies related to "The Biophilic-Design Theory" and "The Attention Restoration Theory". Second, we analyze the application examples of "The Biophilic-Design Theory" and "The Attention Restoration Theory" in domestic and foreign educational spaces. Third, the concept of educational space is set up based on the elements derived from previous studies. Finally, we propose the planning direction of classroom design based on Biophilic-Design. The following conclusions were drawn. First, The creation of the education space to restore the learner's attention requires a visual space plan that utilizes natural elements such as natural light, artificial light, plants, and natural materials that can directly experience nature. Second, the direction in which students in the classroom can be "The Attention Restoration Theory" should consider the use of indirect natural elements that bring the surrounding natural landscape into the interior. This study will be used as the baseline data for the spatial design and planning of education facilities based on Biophilic-Design.

수소는 기후변화 위기에 대응하기 위한 에너지원 중 하나로 주목받고 있다. 그러나, 수소는 밀폐된 공간에 누출되면 천장으로 상승하여 축적되고, 점화원과 만나면 화재나 폭발의 위험이 있다. 특히, 수소를 운송하거나 연료로 사용하는 선박은 여러 밀폐된 공간으로 구성되어 있기 때문에 수소를 안전하게 사용하기 위해서는 공간 내에서의 확산 특성을 파악해야 한다. 본 연구는 선박 내 밀폐된 공간에서 수소와 유사한 특성을 가진 헬륨의 누출방향에 따른 확산 특성을 실험적으로 파악하고, CFD 시뮬레이션을 통해 환기횟수가 25, 30, 35, 40, 45ACH로 증가함에 따라 누출방향에 따른 산소농도 변화를 파악하는 것이 목적이다. 연구 결과, 산소농도감소율은 -z 방향의 누출이 2%, +x와 +z 방향의 누출이 1%였으며, 환기소요시간은 -z 방향 누출이 15분 30초, +x 방향 누출이 7분, +z 방향 누출이 9분으로 누출방향에 따라 산소농도와 환기소요시간에 차이가 있음을 보여준다. 또한, 실험공간에서 환기횟수 35ACH 이상부터는 모든 누출 방향에서의 산소농도감소율과 환기소요시간에 유의미한 차이가 없었다. 따라서, 환기횟수를 증가하여도 산소농도와 환기소요시간이 개선되지 않았기 때문에 본 실험환경에서의 적정 환기횟수는 35ACH임을 알 수 있었다.
