This study aims to comparatively analyze the characteristics of light expression shown in the exhibition spaces of architects Richard Meier and Kuma Kengo, who constructed the element of invisible light into visible forms within space, using diverse techniques and components. As for the methodology therefor, it was attempted to conduct theoretical consideration of light, to experience the spaces of light by producing diverse spaces with architectural space components, that is, space, form, material, structure, and color, and to find out what space characteristics are perceived by perceivers from the interaction of the components. As for the research scope, this study intended to identify the concepts and characteristics of light and compare light in spaces, focusing on works of Richard Meier who constructed functional and mechanical spaces based on Le Corbusier's architectural language in the West and works of Kuma Kengo who claimed regionalism architecture in the East. In particular, this study intended to comparatively analyze the methods of using materials according to the filtering of light that appears different between the two architects in case that light enters into their exhibition spaces, and the effects of light production that arise from the differences, thereby pointing out the characteristics of diverse light expressions within the spaces of modern architecture. On this, this study investigated methodological differences of the two architects, who are based on East and West thoughts, in expressing light in spaces in various forms through brightness and darkness, light transmission and shadows appearing according to the nature of light, and color and materials. It is hoped that this study will provide an opportunity for promoting better understanding about other architectural cultures as well as understanding the characteristics of light in exhibition spaces.

An increasing number of primate genomes are being sequenced. A direct comparison of repeat elements in human genes and their corresponding chimpanzee orthologs will not only give information on their evolution, but also shed light on the major evolutionary events that shaped our species. We have developed REPEATOME to enable visualization and subsequent comparisons of human and chimpanzee repeat elements. REPEATOME (http://www.repeatome.org/) provides easy access to a complete repeat element map of the human genome, as well as repeat element-associated information. It provides a convenient and effective way to access the repeat elements within or spanning the functional regions in human and chimpanzee genome sequences. REPEATOME includes information to compare repeat elements and gene structures of human genes and their counterparts in chimpanzee. This database can be accessed using comparative search options such as intersection, union, and difference to find lineage-specific or common repeat elements. REPEATOME allows researchers to perform visualization and comparative analysis of repeat elements in human and chimpanzee.

Light is an essential environmental element for elderly people to do various activities. At senior welfare centers, healthy indoor lighting is especially necessary because the facilities are used by the elderly to perform their mostly indoor activities. The purpose of this study is to evaluate light environments at senior welfare centers for well-being lighting characteristics. We based the study on the 'Biophilia' theory, a concept related to health from happiness. Thus, this study is mainly based on literary review and survey research. For this, we conducted a location focused field study to identify the current state of the lighting environments at senior welfare centers in Busan, South Korea. First, we constructed structural questionnaire to evaluate lighting environment based on 'Light and Space' biophilia theory. Then, to survey subjective evaluation, the participant of research included total of 122 senior welfare center users. Based on the results of this research, the conclusions are as follows; 1) overall, it seems that the overall result of the light environmental evaluation seems to be high because the evaluated facilities in the case survey in large-scale were recently built elderly welfare centers. 2) most of the healing design elements are focused on the introduction of natural light and psychological influence. The satisfaction with actual natural light is evaluated to be high. Although shadow and reflected light are very important in discrimination and recognition of indoor space and wayfinding, the evaluation of reflected light and shadow was low for the study. 3) items that are related to the functionality of the light were highly evaluated, while the items that are related to the spatiality of the light were rated poorly. This study has its significance when examining the effects of light environments within the welfare center form of the perspective of senior citizens. It can be referenced when reconsidering the recognition of light environment as a major consideration factor to establish a desirable senior welfare center environment.

Recently, construction of bridges in rural areas has been increased to preserve the natural environment. However this brings forth the disputes over rights of light in farmland. In urban areas, the disputes over rights of light have been settled on the authority of the national architectural law and only sunshine hours for winter solstice are considered. Basically, the point at issue is different between each case. The main issues of the dispute in rural area were the reduction of the crop cultivation and the increase of the heating cost in winter. The purpose of this study is to review the mediation process in national environmental dispute resolution commission to resolve these issues, and to set up the analysis method of rights of light and modelling equation of solar position. Furthermore, we aimed at analyzing the damaged hours of daylights in rural housing and the infringement rate of daylight in farmland through the case study. In conclusion, we estimated the sunshine hours during the whole damaged periods according to the elements of bridges, and presented the solution process of dispute over rights of light due to the construction of bridge in rural area.

The dome structure has been treated in two layers among the techniques that have formed the space in Baroque architecture and the light used to be manipulated to create the openness of space and the fantasy of atmosphere. Such an expression technique has influenced on the expression of space in the architecture of New York Five in the 1960s to 1970s and the concept of multiple space embellished with various layers has appeared in the architectural concept of New York Five; meanwhile, the common meaning with the technique of double layers and the ways of phenomenal expressions that have recognized the existence of space in the Baroque period has been achieved through the light, immaterial organism. It means that the existing concept of light limited simply to the plane elements of brightness and darkness has been treated as a formative element that has defined and adjusted the visual expansion and reduction of the space Itself and special existence and has been used as an element of the media of spatial structure. In addition, these elements have been treated as another solution for the emotional aspects of space. Therefore, this study compares the plastic and formative meaning of the Baroque architecture with that of New York Five in terms of the relation between space and light and examines them; in doing so, it will give a clue to understand various and new space expression techniques to many architects and space designers who have led modern architecture.

Due to the development of technology, the modern people became to require not only more convenient life but also more comfortable and emotional environment, and individually suitable living environment is applied to residents in a residential space. Recently, while the LED lighting was variously attempted in every sector in society, it is needed to express differentiated lighting according to the resident's individual lifestyle in a residential space. In this paper, we analyze the role of LED lighting suitable for the digitalized lifestyle of the modern people through the relevant literature survey and case studies. The following results are obtained in summary of the rapidly changed recent trends of LED lighting. First, LED light replace existing light sources due to the advanced new technology in LED industry, and take the spotlight as a new lighting solution with the development of variable color LED bulb and the control technology by the wired and wireless communications. Second, LED lighting can be structurally applicable to every lighting device because of its compact and lightweight units, can produce abundant light environment by expression of variable colors and moods with the easy coloring and dimming control, can be reborn as emotional lighting design. Third, as recently practices are constantly appeared that integrate LED lights in the interior elements, such as object and furniture, and combine advanced LED lighting technology to new materials, the portion of illumination on the indoor environment is further increased after integrating the LED lighting and interior elements make boundaries of lighting and product architecture become blurred. LED lighting is confirmed that is being changed from the external functionality including material, shape, color, and etc. into the contextual emotion design including the lights expression, variable color, brightness control, making image, and etc. as the light source in current smart lighting era.

완전제어형 식물공장하에서 인공광원에 따른 결구상추의 생육, 잎끝마름증과 배양액속의 무기이온 변화를 검토하고자 본 실험을 수행하였다. 인공광원에 따른 지상부 생체중과 건물중간의 유의적인 차이는 없었으나 전반적인 생육은 형광등에서 가장 낮게 나타났다. 인공광원중 생육과 램프의 경제성을 고려해 볼때, 고압나트륨등을 사용하는 것이 좋을 것으로 생각된다. 인공광원에 따른 잎끝마름증 발생시기는 정식 후 14일에 처음 발생하였으며, 발생부위는 자엽으로 부터 9∼10번째 잎이었다. 발생원인으로는 빠른 생장율과 상추의 칼륨흡수로 추정되었다. 그리고 인공광원에 따라 배양액속의 무기 성분 변화를 보면, 세처리구 모두 칼슘. 마그네슘, 구리와 아연 함량 등은 축적되는 경향을 보였으며, 전질소, 인, 철과 망간 함량등은 안정적이었다.
