Recently people show interest in cultural exhibition space targeting on children from the birth of children to play and education. Accordingly, lately the necessity of professional special exhibition space, which is composed of changeable program fit to the children trend of a growth period, and shows relatively more freedom and adaptability in directing the theme than permanent exhibition, have increased rapidly. Today the social importance of special exhibition for children is emphasized as an alternative that can provide efficiently the expression of freedom and the environment of experimental space which is not filled in existing academy or school. The necessity of special exhibition space for children is raising to the climax at this moment, this study has the meaning to analyze the direction of domestic special exhibition for children progressed in last 1 year, and then to suggest basic guide and direction for future plan of special exhibitions.

Massive stars play an important role in terms of their feedback, but their formation process is poorly understood. Direct observational evidence for the formation of massive stars through accretion disks is rare. Hence the detection of disks in massive young stellar objects (MYSOs), if any, could be important to constrain the formation process of massive stars. The inner gaseous disk can be observed by the high-resolution near-infrared spectroscopy. We observed a MYSO, Min 2-62, using IGRINS and detected a double peak feature, which could be an evidence of a rotating disk, in the Bracket and Pfund series lines. We report the preliminary observational results of Min 2-62 with IGRINS.

This paper presents a basic theory of information flow from single sending point to multiple receiving points, where new theories of algebraic system called "Hybrid Vector Space" and flow vector space play important roles. Based on the theory, a new algorithm for finding maximum homogenous information flow is proposed, where homogenous information flow means the flow of the same contents of information delivered to multiple clients at a time. Effective multi-routing algorithms fur tree-shape delivery rout search are presented.

A variety of attempts for trends to overcome the limits of the uniform styles and a fixed dichotomous structure and thoughts, have been made. This research aims to apply and analyze the application of concepts of the liminal space of contemporary architecture based on the destructive inclination of post-structuralism and the theories of philosophers. Space of the past was recognized for a long time focused on functions and styles that support the building. In modern and contemporary spaces, however, the boundary of contemporary space has been blurred with the mingling of cultural phenomenon. In other words, new architectural approaches of expression have been attempted such as structure, styles and materials, in combination of diversified concepts. And, the concept of liminal space is useful to identify the multi-layered and fluid characteristics. This study examines various characteristics of expression on the liminal space characteristics of comtemporary architecture tbased on Herzog and de Meuron's architecture. The result will help us understand the expression and characteristics of the liminal space that belongs nowhere among their architectural spaces. The analysis of the ases of Herzog and de Meuron will play a crucial role in developing new possibilities of modern space and contemporary space of the future.

A study of light in Kahn's architecture must be significance as a work in building new architectural space and a new foundation for architecture, as well as clarification of the uniqueness of Kahn's architectural space and search for its significance. In addition, the study provides a greater comprehension of an the concept of Kahn's architecture by clarifying the degree of association of light into other concepts of architecture. Therefore, this study attempts to examine Louis I. Kahn's statement, sketch and work. His sketch along with the characteristics of the technique how to present it also enables comprehension of other aspects of architecture as a means to revive architecture. Khan's use of light enabled the evolution of primarily two types 'specular surface' and 'unique opening part' by associating them with the need to diminish glaringness. Each of these types has been evolved individually and is indicative of a concept of light that can be largely divided into ' object's light ' and ' space's light ' Object's light refers to a type in which the formative significance of structural part and different directions of light coexist, and its formative characteristics play a role that differentiate places within space. Space's light is present on wall spaces that limit space and exhibits its distinguished role differentiating places within space in the form of 'expression'.

Whistler mode chorus wave is considered to play a critical role in accelerating and precipitating the electrons in the outer radiation belt. In this paper we test a conventional scenario of triggering chorus using THEMIS satellite observations of waves and particles. Specifically, we test if the chorus onset is consistent with development of anisotropy in the electron phase space density (PSD). After analyzing electron PSD for 73 chorus events, we find that, for ~80 % of them, their onsets are indeed associated with development of the positive anisotropy in PSD where the pitch angle distribution of electron velocity peaks at 90 degrees. This PSD anisotropy is prominent mainly at the electron energy range of ${\leq}$ ~20 keV. Interestingly, we further find that there is sometimes a time delay among energies in the increases of the anisotropy: A development of the positive anisotropy occurs earlier by several minutes for lower energy than for an adjacent higher energy.

Today, residential building is considered of be one of the most important space of their quality of life and health. Residential buildings should provide comfortable environments to support the activities of their occupants. And good residential buildings are made by appropriately combining residential spaces, such as living room, master bedroom, bedroom, kitchen, restroom, and so on. These combinations in residential building are must be compatible with the activities of the occupants and their needs. The objective of this research is to investigate and analyze the relative importance and space priority between residential space in residential buildings depending on occupants' characteristics, such as, gender and age. Especially, this research is to find space weighting factors for integrative evaluation in residential buildings based on occupant survey. These weighting factors play an important role in determining the relative importance of various residential spaces for integrative residential space evaluation. And, the result from this research will help designers and researchers to find space planning strategies in residential building, and develop new integrative evaluation framework for improving residential quality from the occupants' point of view.

Objectives: In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. Methods: We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. Results: This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (β=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (β=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. Conclusions: Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

Due to the positive effect of forest space for child development, the creation and operation of forest activity space of various organizations is increasing in quantity; however, the research on practical space design and management program is insufficient. Therefore, the purpose of this study is to evaluate the space and management programs of the forest experience centers through the post-occupancy evaluation of teachers and preschoolers participating in forest activities. To do this, we analyzed the selected twelve sites through field survey, class observation, and interviews with forest education specialists, and then surveyed 115 forest education experts and childcare teachers for importance, performance, overall satisfaction, and space preference. In addition, we accessed overall satisfaction and space preference of twenty-nine preschoolers through interviews, photo-simulation, and questionnaires. As a result, the importance and performance of management program area was rated higher than the spatial characteristics area. In terms of group comparison, the group with active structured program rated two areas higher than the groups with free play. Preschoolers with structured programs preferred facility space, but preschoolers with free play preferred nature. Two preschooler groups rated forest activity as satisfactory. Based on the analysis results: 1) The composition of the forest activity space should ensure accessibility, safety, diversity of diversity, water space, connect to the forest road, and secure various terrains, trees, and natural materials; 2) The management program should ensure that forest activity programs have the proportional balance of structural programs and free play; also. management programs should plan for sufficient free playtime and a high share of play in the forest; and 3) Ensure the role and expertise of forestry specialists and run a program to increase the autonomy of preschoolers.
