Recently, underground spaces can be usually applied to the alternative of land use for parking. However, lack of window and natural light are among the most cited drawbacks associated with dark image of underground. If underground parking lots are designed to be positive and safe environment for people, openings for daylighting will play a significant role. The natural light and unobstructed view to outdoor are main elements to create optimal underground parking lots. This paper focuses on investigating the actual day lighting conditions and evaluating the day lighting performance of openings as potential lighting resources. For the study, the field measurements and Questionnaire surveys are conducted. And then, the day lighting performance of underground parking lots based on opening geometry and orientation are evaluated by scaled model experiments. As results, the feelings of safety and orientation of underground parking lots are improved by openings for day lighting regardless of the sizes. The required illuminances (daylight factor 0.5%) for underground parking lots can be satisfied in the skylight opening ratio of 4% or more.

Streetscape plays on important role in urban cities. Characteristics of streets is basically defined by the building facade, signs, plants and paving during the daytime. However at night, street receives a new appearance due to the shop light from the buildings, exterior lightings, signboards and street light, and it creates most of the image of the streets. This study aims to analyze the luminous environment and its subjective image of two different pedestrian's commercial streets. Insa-dong street and Myungdong street were chosen for the study. Horizontal illuminance and luminance on building surface, advertisement billboards and pedestrian road were measured. Thirty students were asked to rate the five scaled questionnaire on their subjective images of the streets. Statistical analysis including profile, correlation and T-test are conducted and some findings are discussed

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.

Contemporary architecture tends to deconstruct modern architecture based on rationalization just like reductionism and functionalism and secedes from it. It means change from mechanical to organic and ecological view of the world. According to these changes, consideration of a compositive relationship presented variety and complexity in architecture. Thus, the modern speculation based on rationalism cannot provide an alternative interpretation about complicated architectural phenomena. At this point in time, the purpose of this study is to investigate the possibilities of the fractal as an alternative tool of analysis and design in contemporary architecture. In this study, two major aspects are discussed. First, the fractal concepts just like 'fractal dimension', 'box-counting dimension' and 'fractal rhythm' can be applied to analysis in architecture. Second, the fractal formative principles just like 'scaling', 'superimposition trace', 'distortion' and 'repetition' can be applied to design in architecture. Fractal geometry similar to nature's patterned order can provide endless possibilities for analysis and design in architecture. Therefore further study of fractal geometry should be conducted synthetically from now on.

The southwestern islands of Japan, especially southward from Amamioshima Island, have distinguished sets of nature and culture. However, various problems are arising on those islands. This report first introduces island characteristics as well as, their status briefly. Then it introduces conservation efforts. Since nature and culture are closely connected in the island system, conservation of the set of nature and culture is essentially important. From this point of view, this report focuses on two efforts. The first example is the effort for designation of a new national park with a new concept of "environmental culture type" and "ecosystem management type" in the Amami Gunto Islands. This effort is a new challenge to focus on the importance of cultural aspects. The second example is the unique effort of the national park visitor center to conserve as one set of integrated nature and culture with an alliance of all stakeholders in Taketomijima Island, Iriomote-Ishigaki National Park. The visitor center serves not only visitors, but also islanders. These two cases are good models that suggest hints for future conservation measures.

Purpose of this study is to find the research direction to solve the housing problems for the elderly which based on approaches and issues in related studies. Research method was interpretative analysis of the articles issued from 1976 to 2002. Each approach (rationalistic approach, ecological approach, micro-sociological approach, typological approach, environment-psychological approach, welfare approach) produced helpful information and had relative merits. But the researchers must regard housing for the elderly as a social problem in macroscopic view to solve the housing problems for older people with welfare approach. As a result, to solve the housing problems with welfare approach for the elderly who live in their own place with community care, studies about lifetime home, care and repair, and management of housing for the elderly might be needed. And research about existing services, transfer system of services, financial problems, man power to manage the system might be needed to spread out the services to the middle class elderly.

Bus station is a public space which many people use and various activities are occurred in urban life. Main activities are waiting for departure or passengers with the feelings of joys and sorrows. Also sound information including announcing message of arrival and departure are to be considered carefully. Considering these roles of bus station, creating acoustic amenity is a prerequisite to the spaces. In this study, the spaces of bus station were classified into 4 spaces such as approaching path, waiting palace, departure and arrival platform. Observation survey was conducted to extract various activities in the view point of sound in each space. And subjective response was analyzed before and after introducing prepared sounds.

Growing use of entire glass facades with metal frames are popularly witnessed in modern building practices and design competition as well. In spite of architectural aesthetics and view to outdoors, environmental issues still exist in that kind of buildings. One of the solutions for the problems might be the use of functional glasses such as a heat-resistant glass or various tinted glasses for the glass walls. This paper aims to provide performance data related to the impact of various transmittal materials of window systems on the light distribution. A series of computer simulation deals with the basic geometrical and optical design elements of a commonly used all-glass facades. Additionally an experimental configuration of the vertical window is proposed for better result of daylighting. A window system equipped with an inner-light shelf can improve the uniformity of natural light in a space by reducing the level of illumination near the window and redirecting light deeply into the space.
