This paper call attention to the characteristics of apartment unit plans as to the outdoor adjacency methods. My arguments will attempt to investigate spatial composition and each room sizes of the unit plans. So far, very little has been done in this direction. I will limits myself to study 573 plans which have been designed from 1996 till 2003. What emerges from this analysis is that these samples divided 3 types derived from the outdoor adjacency methods. Type 1 limits itself to 39 square meters unit plans. Type 2 was distributed from 49 square meters to 200 square meters with the exception of 100-110 square meters. And, type 3 ranges from 59 to 160 square meters. Therefore, it could be profitable each room's environmental condition (daylight, ventilation and etc) and diverse apartment building types to design in extent 49-160 square meters.

This paper deals with torque harmonic characteristics and its reduction design of induction motors for electric vehicle (EV) propulsion. For calculating the stator harmonic flux of squirrel-cage induction motor, the numerical methods have been employed on the structural configuration design of stator and rotor teeth. In particular, torque ripples including spatial harmonics are obtained by Finite Element Method (FEM), and their individual harmonic components are identified with Fast Fourier Transform (FFT). In this paper, design modification on the teeth surface gives rise to the significant reduction of torque ripples including spatial torque harmonics, which have been obtained with FEM.

We propose a speckle reduction technique in electronic holographic display systems, where digital micro-mirror array devices are used as spatial light modulators. By adopting a programmable filtration in a general 4-f optic configuration, it is shown that the signal spectrum components in the frequency domain of a viewing-window-based holographic display system can be selectively filtered. Compared to the widely utilized single-sideband filtration techniques in electronic holographic display systems, our proposed programmable filtration can be utilized to effectively reduce the speckles in the reconstruction of point-cloud-based computer-generated holograms. Experimental results are presented to verify our proposed concept.

Richmedia Service means that interactive media service can provide view with various multimedia elements(such as Video, Audio, Text) at same time. Various Multimedia elements can be serviced by Scene Description technology standards like BIFS(Binary Format for Scenes) and LASeR(Light Application Scene Representation). By providing Scene Component information, richmedia service is available to various multimedia services. so users is available to personalized services fitting temporal and spatial options. In conventional technology, when the scene is changed by user or service, mobile deletes the scene of configuration information and makes new scene of configuration information. this is a very inefficient way. In this paper, Propoesed that by using DOM(Document Object Model) method, to pass only the dynamic configuration part, changes scene method.

This study is aimed at analyzing desired spaces and demands for their improvements, and subsequently proposing the design plan for eating and drinking places for solo diners by surveying the user satisfaction based on the analysis of the space configuration, and the physical environment of eating and drinking spaces for solo diners. Theoretical discussions about eating and drinking spaces for solo diners and their physical environment were reviewed from the previous studies, and an on-site survey was conducted with a checklist, for which the items regarding configuring elements of physical environments for the satisfaction with eating and drinking spaces for solo diners have been derived. Measurable checklist items according to the configuration of eating and drinking spaces were derived for this survey, which had then been conducted with diners in the eating and drinking spaces for 2 weeks. The analysis results are as follows. First, cleanliness is required as a necessity for the user satisfaction in eating and drinking spaces for solo diners. Second, a '-' shaped bar and the spaces to utilize and combine additional facilities are required in the central service space. Third, the self service should be performed in the additional service space. Fourth, the menu composition and the location selection considering main age groups of diners are needed. Fifth, interior design elements need to be improved to allow diners to feel visual interest along with enjoying food and beverage. It is considered that the strategies of spatial design need to be analyzed and proposed from the perspective of design among the physical environments of eating and drinking spaces for solo diners in future studies.

Purpose: The characteristics of site plan and space configuration of public dentistry through examining the public dental healthcare centers for the disabled in Korea and comparison between them are necessary for the development of planning of the dental healthcare system. This study has been started to provide basic informations such as nationwide distribution, site relationship, and space configuration for the planning of public dental hospital architecture. Methods: Literature review of publicness and public dental healthcare and investigation on current status of public dental healthcare center for the disabled in Korea have been conducted. The site plan and space configuration of eight public healthcare centers for the disabled have been analyzed. Results: The result of this study can be summarized in three points. The first one is that public dentistry in Korea are distributed public dental hospital for the disabled in Seoul and public dental healthcare centers for the disabled in eight provinces. The second one is that the types of the dental healthcare center for the disabled are divided with remodeling type which is diverted from existed dental or medical out patient clinic space or independent building type which is planned with a new and exclusive usage for the disabled. The third one is that the space configuration of dental healthcare center for the disabled is needed more required programs, larger treatment unit space, and more private clinic space than typical dental treatment plan. Implications: This study is the starting point for the research of public dentistry and it is necessary to analyze the dental prevention and dental public policy to develop the public dental healthcare system.

There is an inseparable relation between human race and engineering work. As world developed into highly industrialized society, a diversity of large structures is being built up correspondently to limited topographical circumstance. Though large structures are national establishments which provide us with convenience of life, there are some disastrous possibilities which were never predicted such as ground subsidence and degradation. It is very difficult to analyze the volume of total metamorphosis with the relative displacement measurement system which is now used and it is impossible to know whether there is structural metamorphosis within a permissible range of design or not. In this research with an object of 13-year-old earthen dam, through generating point-cloud which has 3D spatial coordinates(x, y, z) of this dam by means of 3D Laser Scanning, we can get real configuration data of slanting surface of this dam with this method of getting a number of 3D spatial coordinates(x, y, z). It gives 3D spatial model to us and we can get various information of this dam such as the distance of slanting surface of dam, dimensions and cubic volume. It can be made full use of as important source material of reinforcement and maintenance works to detect previously the bulging of the dam through this research.

Because fire has significant impacts on fauna and flora in forest ecosystems, as well as socioeconomic influences to local community, it has been an important field of study for decades. One of the most common ways to reduce fire risk is to enhance fire-resilience of forest through fuel treatments including thinning and prescribed burning. Since fuel treatment can't be practiced over all forested areas, appropriate and effective strategies are needed. The present study aims to look at the relationship between spatial characteristics of forest structure measured with landscape pattern metrics and burn severity to provide guidelines for effective fuel treatments. Samchuck fire was selected for the study, and 232 grids covering the study areas were generated, and the grid size was 1km. The burn severity is measured with dNBR derived from satellite imagery, and spatial characteristics of forest structure were measured using FRAGSTATS for both landscape and class levels for each 1km grid. The results of this study strongly indicated that heterogeneity in composition and configuration of forests may significantly reduce burn severity. By enhancing heterogeneity of forests, fuel treatments for fire-resilience forest could be more effective.
