The light has been considered as a main character that can not be omitted in architecture since ancient time. The recognition of space by light means that light makes the fictional space recognizable concretization. Light and shade make emptiness and substance can be easily recognized. Also reiteration and location of light and shade change the degree of acknowledgement. The character of light can strengthen or weaken the power of recognition concerning territory, direction and location. Also it can broaden, close, and segregate the domain and eventually strengthen recognition. In this study, I will try to find how space can be recognized with the help of light in architectural territories in terms of actual states. Also the main aim of my study will be the study of the light application in real space with the architectural example of space recognition by light and possible opportunity of it in space plan.

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.

Purpose: This paper tried to understand the architectural philosophy of Laurant Beaudouin who is one of Neo Corbusian architects. They were in succession to Le Corbusier's principles of modern architecture, and developed his concept of modern architecture with their own creative architecture, and formed a big achievement in the contemporary architecture. As a representative Neo Corbusian architect, the design concepts and principles of Laurant Beaudouin were analyzed in relation of nature, light and space. Method: Three step study was conducted for the paper; Firstly, investigated significant his architectural characteristics as a neo corbusian architect in the point of view of plan libre, architectural promenade and light; Secondly, analyzed his architectural philosophy on light, gravity and color, Finally, deducted relation light and space through analysis 5 works of Beaudouin. Results: According to the results of the study, Laurant Beaudouin has greatly developed of Corbusier's principles and philosophy of modern architecture, and then, created his own originative architectural works by combining nature, light and space and presented architectural promenade with the change of time.

This study is intended to analyze the way of incorporating the effect of natural light into the architectural space design by Le Cobusier. The composition of modem architectural space is significantly different from that of classical architecture. Such transition is attributable to the change of tectonic method which was supported by the development of new materials and structural systems. In addition, the effect of natural light systems which is one of the main elements in architectural space has undergone significant changes in modern ages. Moreover, Le Corbusier introduces the new concept of natural light in his works. By bringing the above two trends together, this study analyzed the way how Le Cobusier applied light effect in his works. Specifically, findings regarding the 'traffic flow in the space' with the light, 'elevation effect' with the 'Brise soleil' in Le Cobusier's works were presented. And also the way of lighting the object in the space was presented.

These days we are more interested in the space of architecture that how the change is likely to affect and how to be realized human. Human beings are recognizable the space and the creation of the space is eventually effected through human beings being perceptible the space of architecture and the equivalence of the space. That is the light, one of phenomenological elements, has been the first visual experience at birth. This study will concentrate on the importance of the phenomenological light especially indoors and study how architectural elements influence human beings with the light as one of the basic design factors for human life. That is exactly purpose of this research paper and this paper can make our lives worth living significant with the actively various uses inside spaces through the phenomenological light as a natural light in our human beings.

Purpose : Ando Tadao has his own unique architectural conception to reproduce natural view on site, and he continues to create new architecture without regarding to any principles. Ando Tadao experiments his imagination through the museum architecture, starts organization of space with light, and completes organization of space with light at once. Methods : The research works as follows: 1) Analyzes the meaningful characteristics showed in his architectural works. 2) Analyze organization of space and use of light in museums designed by Ando Tadao. 3) Selecte his representative museums in Korea and Japan, and then analyze space composition and light use through literature study and field survey. Result : The organization of museum space by Ando Tadao has a close relationship with the light. Light designed by Ando Tadao represents unique architectural varieties such as cushioning space, moving line, spatial characterization, and natural influx.

We have conducted a study to control the light-intensity distribution at the output end of a multimode optical fiber via estimating the transmission matrix. A circularly arranged Hadamard eigenmode phase distribution was implemented using a spatial light modulator, and the transmission matrix of a multimode optical fiber was experimentally obtained using a four-phase method. Based on the derived transmission matrix, the spatial phase distribution of light incident upon the optical fiber was adjusted via the spatial light modulator in advance, to focus the light at a desired position at the optical fiber output. The light could be focused with an intensity up to 359.6 times as high as that of the surrounding background signal at a specific position of the multimode fiber's output end, and the intensity of the focused beam was on average 104.6 times as large as that of the background signal, across the area of the multimode fiber's core.

In this study, we developed and applied 15 evaluation questions about light to 30 middle school students in K University Science Education Institute for the Gifted. Then we used the theory of knowledge space and analyzed the middle school Science Gifted Students' knowledge state about light. By schematizing the hierarchy from it, we intended to not only measure students' knowledge state about light, but use it as the basic materials to improve teaching methods. To achieve the purpose of this study, we analyzed the evaluation results and individual knowledge state and hierarchy of questions. As a result, there were different knowledge structures in the individual, and we found that we should diagnose them differently. In addition, we have had implications that it has the connection with each questions and the individual knowledge state.

영상기반 렌더링(image-based rendering) 기법은 전통적인 컴퓨터 그래픽 기법과는 다르게 장면 생성 시 복잡한 3차원 정보들을 2차원 영상들의 조합으로 표현하여 렌더링 하는 방법이다. 그 중에서 원통맵을 이용한 렌더링은 파노라마 영상을 이요해 관찰자에게 보다 빠르게 실시간으로 장면을 렌더링하여 보여준다. 이러한 영상기반 렌더링에서도 ㅅㄹ제감을 보다 더 높이기 위해서는 빛과 빛에 의해 생기는 그림자, 하이라이트의 역할이 매우 중요하다. 하지만 파노라마 영상의 경우 미리 촬영된 영상들을 사용하므로 실시간으로 동적인 광원의 변화와 그로인한 그림자와 하이라이트 부분을 표현하기 위해서는 변화된 영상들을 재촬영하여 새로운 파노라마 영상을 제작해야 한다. 본 논문에서는 OpenGL을 이용하여 실내 공간을 표현한 원통 영상 기반 환경 맵에서 광원의 위치변화에 의해 가상 하이라이트 (virtual highlight)의 움직임을 파노라마 이미지의 재 촬영 없이 몇 가지 기하학 정보만으로 계산하여 표현해 주는 방법을 제안한다.

사람의 눈은 카메라와 흡사한 구조와 원리를 가지고 있어서 빛을 직접 받는 경우 조리개가 오므라지게 되어 오히려 피사체를 인식하는 데 어려움을 겪는다. 그 이유는 광원과 피사체 간의 조도(밝기) 차이로 설명할 수 있다. 사람의 동공은 눈으로 들어오는 빛의 밝기에 따라 커지고 작아진다. 따라서 광원이 너무 밝은 경우에는 상대적으로 피사체에서 반사된 빛이 안구로 적게 들어와 피사체가 오히려 어두워 보이는 결과를 초래한다. 대부분의 사람들은 이 같은 사실을 간과한채, 조명은 무조건 밝아야 한다고 믿어 왔으며, 그 결과 우리가 속한 모든 건물들은 직접조명 일색이다. 선진국에서는 이미 조명이 인체에 미치는 영향에 관한 연구가 지속적으로 발전함에 따라 이미 오래전부터 간접조명 방식이 채택됐다. 간접조명의 효과는 영역을 넘어서서 건강한 실내 공간을 조성하는 필수적인 요소로 자리매김하고 있다. 이제 현대인들은 눈에 피로감을 주는 노출형 조명보다는 점차 눈을 편하게 해서 몸과 정신의 피로를 릴렉스 시켜주는 간접조명방식으로 나아가야 할 것이다.
