The purpose of this study was to investigate the effects of task conditions (physical similarity between the spatial product and the reference space, presentation place of the spatial product) on children's spatial representation. The participants consisted of 40 3-year-olds and 40 4-year-olds. The results of this study are as follows. Both 3-year-olds and 4-year-olds were capable of a greater degree of spatial representation when there was a high level of physical similarity between the spatial product and the reference space, and when the presentation place of the spatial product was in the reference space. 4-year-olds were capable of more accurate spatial representation than 3-year-olds. There was no significant difference in the children's spatial representation depending on the type of spatial product (scale model, map). The results revealed that the physical similarity between the spatial product and the reference space and the presentation place of the spatial product are essential in young children's spatial representation. Additionally, the results indicated that spatial representation of children develops gradually from when they are three to when they turn four.

Heat pipe cooled nuclear reactor has been a very attractive technical solution to provide the power for deep space applications. In this paper, a 200 kWe space nuclear reactor power design has been proposed based on the combination of an integrated UN ceramic fuel, a heat pipe cooling system and the Stirling power generators. Neutronics and thermal analysis have been performed on the space nuclear reactor. It was found that the entire reactor core has at least 3.9 $ subcritical even under the worst-case submersion accident superimposed a single safety drum failure, and results from fuel temperature coefficient, neutron spectrum and power distribution analysis also showed that this reactor design satisfies the neutronics requirements. Thermal analysis showed that the power in the core can be successfully removed both in normal operation or under one or more heat pipes failure scenarios.

The purpose of this study was to clarify the space use pattern and the daily living activities of the elderly with dementia in the common space (dining room, day corner) of nursing home in Japan. The subjects were six units of the 2 nursing homes in Tokyo. For this, researcher visited from September 5 to December 5 and collected data by observations of behavior of the elderly with dementia in common space and interviews with staff for the information about basic characteristics of the elderly with dementia and administration and operation of the facilities. The data were analyzed using the frequency and percentage with SPSS 11 program and recorded in the form of behavior map. The results revealed as follows: first, 6 types (self-concentration type, physical environment-interest type, passive others-interest type, staffs-interaction type, other elderly-interaction type, visitors-interaction type) of the daily living activities of the elderly with dementia in common space were founded. Second, the daily living activities of the elderly with dementia in common space tended to focus on self-concentration type and physical environment-interest type. Third, physical environmental characteristics of common space affected space usage pattern of the elderly with dementia. And it was perceived like as living oriented space, social interaction space, facility space, staff oriented space. Conclusively it was suggested to plan dining space as semi-private space, day comer as semi-public space.

This study aims to analyze the actual state, the satisfaction index, and the satisfaction factor of the residents in the apartment adopting thematic outdoor rest space design. This study also proposes the basic data for the standard of resident-centered rest space design, not designer-centered or fashion-followed design. The results are as follows : First, most residents use near by rest space, and more use occur during the evenings; 17 hr. ∼ 21 hr. Most of residents use the rest space with their children, partner, or family. Residents usually take walks and take a rests in the rest space. Most residents use the rest space quietly. Of the rest facilities in the outdoor rest space, benches are most used, walks and pergolas are more frequently used. But waterscape facilities are not particularly used. The satisfaction index of the outdoor rest space is generally low. However, the satisfaction index of the rest space and facilities type shows that the evaluation of rest facilities(e.g. benches) is high. The satisfaction index of the decoration shows that the evaluation for the color and design of facilities is high. In the satisfaction index of the physical environment, the item about the size of rest space is highly appreciated. In the mental satisfaction index of the rest space, the item about whole atmosphere is highly appreciated. Of the factors affecting the general satisfaction index with outdoor rest space, the factor of physical environment is the most important independent-variable. Physical environment and facilities are more important influential factors than the atmosphere of outdoor rest space. In the future, the practical study searching for the preferences of the residents and the activation of use should be preceded.

With the continuous development of artificial intelligence using computers in the Fourth Industrial Age, the virtual space created by virtual reality experiences boosted by the power of artificial intelligence, provides a new experience for us. The purpose of this study is to explore the new aesthetics that the fashion industry provides to users in virtual space created by virtual reality technology. This research method is based on theoretical research on virtual reality technology and virtual space and constructs a research model applied to this research. The scope of this study is the application of virtual reality technology to fashion shows, fashion exhibitions, and fashion design apps on the website of professional virtual reality technology and fashion for the last five years from 2014 to 2019, which actively merged virtual reality technology with modern fashion. We will analyze the cases one by one. The results of this study are as follows. First, this study shows that the constructed virtual space of modern fashion using virtual reality technology creates three kinds of physical space, perceptual space, and imaginary space based on the commutative theory of virtual space formed by Swedish scholar J. $Widestr{\ddot{o}}m$. Second, virtual reality technology applied to fashion shows, fashion exhibitions, and fashion design apps is characterized by four aesthetic characteristics of presence, perceptual expansion, interactivity, and immersion in physical space, perception space, and imagination space.

Current improvements on the standard of living reduced working hours and increased leisure time. Therefore, people's ideas on life style changed and different demands on residential environment are being made. Residents of apartment want a community facility that enables constant exchange with other residents and supports living. Ideas on how to use physical space to strengthen a community is becoming an issue these days. Community facility plays a crucial role in giving a certain characteristic to the whole apartment and improving the image as a community. It also provides a physical environment and induces active participation of community life from apartment residents. The community facility in an important environment for children, which helps them develop in growth and in society as well. Community facility is a space where children fulfill their curiosity and amusement. Since children are greatly influenced by the physical surroundings, community facility for children should not remain as a space for fun but should change into a space for interaction. This study chose six apartments at Dongtan New Town, located in Hwaseong, Kyunggido. This study focuses on the characteristics of design for children's community facility and would like to make a proposal about future space planning for children's community facility.

To transmit users' intentions that vary with each person, intuitive and hi-directional interactions between users and a computer are necessary. We considered these interactions by dividing them into two spaces, physical space and informational space. Informational space supports human thinking process by arranging and visualizing much information. Physical space reproduces the real world where various restrictions exist to virtual space. From the viewpoint of three aspects - contents model, kansei model and context model - we defined the style of the interaction between user and multimedia database. In this paper, for the purpose of examining the way to realize the interaction based on these models, we developed interior design coordination support system and garden coordination system, and then evaluated them.

This study suggested the environmental components for open space in a healing environment based on the social support approach for integrating and enhancing users' activities and interactions. The physical environments of the open space in healing facilities should be suggested by social support design and support the interactions of various users. Particularly architectural environment conditions should reinforce the contribution to the revitalization of medical facilities based on improving the healing effect of patients through mutual exchange of users. The open space environment conditions influence users' healing process with physical design factors and users' interactions, and the flexible environments based on the social support that is crucial for circulation and mutual exchange of users. The open space transformation, integration of technology, and wayfinding system with color and signage also allow users to improve the space experience and easy access. The environmental components of open space design should include easy access for user inflow, flexible layout for comfort, access to outdoor spaces, integration of warm color schemes for relaxation, personalization of spaces with artwork, and visual interest through the use of textures and materials.

The purpose of this study is to analyze the continuous forms of time and space that work as architectural design principles of the Memorial to the Murdered Jews of Europe (Jewish Memorial). Continuity is divided into two, physical and non-physical attributes. The former extends from small installations to furnitures, finishes, spatial composition, and even spatial networks that complete architecture, and the latter is tied to time, from traditional to historical, developmental, commemorative or memorial elements. They are inherent in architecture as continuous forms. The Jewish Memorial is analyzed by the analysing framework of these two items. The analysis of the two layers can be summarized as follows; physical continuity is found in the space networks of the Memorial's inside and outside, the undulating spaces, the finishes, the small furnitures and installations, the entrances of staircases, the expanded underground of the ground order, and non-physical continuity manifests in the topological variation of spatiality, the morphological development of memorial architecture, the connection of semantic sense of space, and the superposition of historicity and modernity. These forms of continuity do not aestheticize the German enormity history, but make the meaning of the Memorial into non-superficial, in-depth architecture as a monument. Thus, the results of this study show that physical and non-physical continuity should be considered as the important design principles of architecture that makes the Memorial architecture possible.
