The purpose of this paper is to introduce the concept design and the structural strength of the double-deck rolling stock vehicle. Aluminum is very useful material for the carbody structure due to its characteristic of light weight. Large alumillum extrusion profiles(panels) have toe of merits such as easy production of complicated shapes, reduction of welding and cutting lines, and cutting down the labor cost. AED type is being applied to the standard EMUs and the EMUs Kwangju subway in Korea. Light material recommended the double-deck rolling stock vehicle because the center of gravity of the train is higher and its weight is heavier than those of the normal vehicle. So we applied the technology of the large aluminum extrusion profiles(panels) to the double-deck vehicle. We performed the structural strength analysis and examined its safety.

The purpose of this study is to find out the way of embodying architectural concept in Nussbaum Museum for complementing present abstract and generalized research. This study tries to examine the close relationship between a certain concept and Nussbaum museum through analyzing architectural characteristics and searching its principles by concrete application of concept. The Architectural concept "Museum without exit", which Libeskind applied to Nussbaum Museum, is based on the dramatic life of Jewish painter Felix Nussbaum with relation to Holocaust, physical background of site and features of program, Libeskind Applied his architectural concept from the beginning to the most parts of the museum. His new museum subverts notions and logic of general features of existing museums. Libeskind's architectural concepts are especially applied to site plan, massing, circulation and spatial configuration. "Museum without exit" creates labyrinth like circulation based on stories including Nussbaum's life, his painting tendency and circumstances of those days. It also realize sensuous space through spatial shape and light control. Although some critics criticize that this museum is not suitable for paint collection because of overwhelming strength of architectural space. However, considering this museum's function of a kind of Holocaust museum beyond personal art gallery, Libeskind's 'museum without exit' shows effective realization of architectural concept for Jewish painter Felix Nussbaum's museum.

Mount Angel Abbey library shows not only the general characteristics which Aalto had shown in his 60s but also special features of his last library project. Special features of Mount Angel library are the result of considering geography and existing context of the site. General characteristics of the library mainly come from the Aalto's concept for library especially considering light. Due to steep site, Mount Angel Abbey library has multi-layered and dynamic spatial configuration. Aalto considered the importance of daylight in the library and applied various kinds of openings to induce natural light. Therefore, Mount Angel Abbey library is the final result of his library type that developed from the Viipuri library of 1930s and his architectural thoughts of 1960s. As a combination of space and light, Mount Angel Abbey library is the outcome of Aalto's unique functional thoughts which maximize the function of the library through efficient induction of natural light.

At the present time, buildings are designed higher and more complex than ever before. Therefore the potential disasters are happened such as fire, power outage, earthquake, flood, hurricanes. Their disasters require people inside buildings to be evacuated as soon as possible. This paper presents a new disaster evacuation guidance concept of inner buildings, whiche aims at integrated the constructing of a sensor network and a guidance light networks in order to provide a quick detection of disasters and accurate evacuation guidance based on indoor geo-information, and sends these instructions to people. In this paper, we present the integrated logical model based on sensor and guidance light networks for the fire disaster management in inner building using our concept. And we verify proposed logical model according to experiments with visualization and operations on map.

The purpose of this study is to explore how to make use of the light and expression methods to embody phenomenal space by considering the representation techniques and characteristics of a variety of 'Phenomenal light' in his works focused on the Steven Holl's views that thought the light as object of creating space. The process is summarized as follows: (1) Study on the relationship between light and color, Classify concept and type of phenomenal light by phenomenal color (2) Consider the characteristics and expression methods of the phenomenal light in the Steven Holl's architecture (3) Finally, organize the concepts and representation techniques of phenomenal light, and then present method to embody phenomenal space by light. According to this, the results are as follows: (1) Perceptual color by the light of the sense forms a variety of perception and texture of light and shadow according to the contrast of shades and the change of materiality, thus embodying multisensory space with the light as the medium approach that helps to experience formal and tactile senses. (2) Spatial color by the light of volume distinguishes the flow and movement of sight, and embody inducing space with the light as Atypical activity that forms atmosphere of space through concentrated or overlapped mass of light and darkness. (3) Existential color by the light of the light source visualizes the existence of the uncertain light, and embody the receptive space with the light as emotional communication that forms symbolic and psychological meaning through metaphorical phenomena of colored light.

Currently, in South Korea, 'Light Pollution Prevention Act by Artificial Lighting' has been enforced. For advertising lighting, it is limited based on only the light-emitting luminance. Luminance is a concept related to the glare. Not only the luminance of the light source, but also glare is affected depending on some situations like blinking, luminance contrast, background illuminance. This study conducted glare subjective evaluation with brightness, color, and blinking by looking at the LED lighting box. The results showed that the glare indexes were higher about 2 times in a decrease of background illuminance from 100lx to 0lx. The glare index of R, G, B light was higher than that of white light. The average glare index of the blue light was higher about 8 times compared to 2,700K. And the blink rate had little effect on the glare, but it affected the irritation. Therefore, the glare effect of light color and blinking needs to be considered for the standard of luminous environment.

The purpose of this study is to extract design concepts, especially in relation to light, as a part of extracting design concepts in architectural interior design. This study consists of two steps. Firstly, appropriate design concepts are extracted from various design characteristics. Secondly, these concepts are classified in the frame of other components of architectural space, as well as in the frame of the plastic characteristics of light. Various design characteristics were analyzed, those of which relating to the plastic character of space, namely, visual phenomenon. As a result of the analysis, 32 concepts were extracted. These concepts, in the frame of other components of architectural space (space, form, structure, opening of space, material, color, inside & outside relationship), were classified, as well as In the frame of the plastic character of Light (transparency, perception, direction, ornament). As the results of this research, the suggested design concepts will be a study material, available to the interior designers as well as students who want to utilize the organized study concepts.

Renzo Piano was first introduced to us when he got together with Richard Rogers and won the Grand Prize on Center George Pompidou Competition in Paris. Since then, he designed number of world renowned museum architecture such as Menil Collection & Museum, The Cy Twombly Gallery, Beyeler Foundation Museum, and most recently the New Pavilion of High Museum of Art. His museum design, in particular, showed very consistent feature which is differentiating the 'Served Space(exhibition area) and the Servant Space(service core or mechanical system area)'. In addition, the way he treats natural light as a special feature within his museum space was nicely done and it is remarkable both in design and engineering side; he always designed a very unique roof structure system to give life and to simulate emotion of light within the space. These are just a few points of his special design characteristics which differentiate him from the rest of the architect working today. While interested by works of Renzo Piano, we found that his work had very close relationship to Louis I. Kahn's design. Specially the way Renzo Piano differentiating serving and servant space and the way he treating natural light. Therefore, the purpose of study is focused on providing typology of museum exhibition organization as well as finding evidence of Louis I. Kahn's influence and concept he has shown in his museum projects through actual site visits and reference research. The method of research was as the following; first to find typology and its characteristics of exhibition space organization of all Renzo Piano's museum projects. Secondly to distinguish projects which show 'differentiated servant and served space'. As the result of this study, it was clear that Renzo Piano had influence of Louis I. Kahn on adopting 'Servant and Served Space' concept. But the research concluded with the facts to approve the uniqueness of Renzo Piane's design concept.
