When apartment buildings are builed and re-builded, they tends to be taller. This tendency causes the problems for solar access and view in the neighboring area. So the impact factor of sunlight and view by apartment building in its neighboring area is examined. The results of this study are as follows： When analyzing sky view by dividing the sky vault into the differential area, the analysis of view can be efficient. The shorter the apartment building, the more the continuous solar access time. And the taller the building, the more the accumulated solar access time. As the height of building is taller and it is farther from the border of apartment building, view ratio, sky view ratio, and form ratio are increased. It implies that the slimmer the building, the more the visual environment can be improved.

The diagnosis of bridge serviceability is carried out by a combination of in-situ visual inspection, static and dynamic loading tests and analyses. Structural health monitoring (SHM) using information technology and sensors is increasingly being used for providing a better estimate of structural performance characteristics rather than above traditional methods. Because the mechanical behavior of bridges with various kinds of damage can not be made clear, it is very difficult to estimate both the damage mode and degree of damage of existing bridges. In this paper, the sensitivity of both static and dynamic behaviors of bridges are studied as a measure of damage assessment through experiments on model bridges induced with some specified artificial damages. And, a method of damage assessment of bridges based on those behaviors is discussed in detail. Finally, based on the results, a possible application for structural health monitoring systems for existing bridges is also discussed.

Development of mobile technology has brought a rapid change in people's lifestyle. Mobile is currently expanding its scope and diffusing the range in diverse fields of smart environments. Many of the means are being used as an alternative of communication by users in the mobile environment. Among them, it is currently in an increasing trend of using mobile stickers as a means for communication. This study is intended to analyze mobile stickers as a means for communication and seek for a direction of development of mobile stickers through analysis on user preference.

The Paper aims to survey and analyze the meaning 'Absence of body' from clothes as non-verbal communication medium. Two types of absence of body from clothes are clothes as object because of removing body, and flattened colthes to deny the body form. In results of analysis, 1)the confrontation of male/female was represented by positive/negative, active/passive, present/absent. 2) male/female means social/private, body/clothing, relevant/irrelevant, subjective/additive. 3) one/numbers, simple/various, limited/free present the various way of waering. 4) tradition/contemporary is expressed by materials 5) enlarged clothes expresses the cynical attitude about body 6) inside/outside , one dress/layered dress suggest new concept to wear against traditional way of wearing.

인천공항 웹사이트에 공개되어 있는 여객운항 데이터를 수집하여 공항정시운항분석을 위한 데이터마트를 두 가지 구축하였다. 이를 바탕으로 항공사별, 국가별, 출항지별, 목적지별 출도착 패턴분석을 실시하였다. 각 데이터마트는 요일, 시간 등과 같은 시간차원, 운항도시, 경도좌표, 위도좌표등과 같은 공간차원, 항공사, 공항게이트, 지연여부, 경유여부, 출도착여부 등과 같은 일반차원으로 구성되며, 예정시간, 실제시간, 지연시간, 지연율 등과 같은 측정지표를 가지고 있다. 특히 데이터전처리 과정을 통해 각 운항도시의 경. 위도 좌표값을 추가하였고, 이에 따라 세계지도 위에 정보를 디스플레이하는 시각화 분석도 실현 가능하게 되었다.

The purpose of this study was to describe preschoolers' perceptions of fear from their own perspective. Qualitative data from 213 preschoolers 4 to 6 years of age were obtained by semi-structured interviews. The fear inventory was analyzed by content analysis and frequency. The most common fears of preschoolers in this study were fear of ferocious animals and imaginary figures, such as tigers, lions, snakes, spirits and ghosts. Fear of ghosts was the primary fear of both boys and girls. Results showed that most fears were caused by disgust-related visual images. Worry about injury and pain was another common pathway to fear. At-risk preschoolers scored significantly higher than normal preschoolers on fears of criticism and getting an injection.

Objectives : This study was to investigate the relationship analysis in VDT(visual display terminal) of work hours. Methods : Questionnaires were completed by 41 women in VDT operations. The information was used to estimate multiple regression for the VDT of work hours related factors association. Results : The prevalence of the VDT of work hours was significantly higher in the shoulder which followed by the neck, the hand and fingers, the arms, the lowback, the back. The VDT of work hours decreased with aging. The VDT of work hours increased with work duration, single, lower among habitual exercise. The desk height, the seat pan height, the posture on the sitting, the elbow angle all did not meet the recommended criteria. Conclusions : Data from this study support a statistically significant association with satisfaction for occupation.

After Computer-based PD measurement was referred in the 1970's, the new technology and a number of digital system have been studied. And the selection of PD patterns, extraction of relevant information for PD recognition are discussed because the number of pulse as a function of discharge magnitude and discharge pulse as a function of the power frequency cycl4e offer the information of the aging insulation. This paper investigates the discharge phase($\phi$) and magnitude(q), as well as the number of discharge(n) with regard to discharge signals generated in power cable. Therefore, according to properties analysis on the distribution of $\phi$ , q and n, it is able to apply in the aging analysis of power cable which visual observation is impossible and distribution change of discharge signals offers much information for risk degree on aging progress of insulation materials.

In this paper, we proposed a new VLSI architecture which can generate computer-generated hologram (CGH) in real-time and implemented to hardware. The modified algorithm for high-performance CGH was introduced and re-analyzed (or designing hardware. from both numerical and visual analysis, the infernal number system of hardware was decided. CGH algorithm and precision analysis enabled to propose a new cell architecture for CGH. The operational sequence was analyzed with the architecture of CGH cell and the characteristics of the modified CGH algorithm, and finally the pipelined architecture and the operational timing were proposed.
