The relationship between users and physical elements of environmental gives a space special characteristics. The Environment Probabilitism by Altman shows that behavior and environment, both response, effect each other construct their characteristics. People can choose their response consciously or unconsciously during their walking , sitting, standing, talking in their environment. Designing a good place can lead people to the goal that they want and designer intend to get, A good place well designed as an positive place is organised with 3 points(1) User's behavior (2) physical elements in environment (3) meanings produced between behavior and physical elements. In this study the importance of physical elements are focused on. In the place where we can have permeability, variety , legibility, robutness, visual appropriateness, richness, personalisation physically , these characteristics will encourage people to have strong motivation and to choose the most active way . From this perspective the circulation of physically handicapped persons is analyzed into their behavioral environment and their behavioral response. The analysis shows the handicapped in our situation has no environmental right for a man itself ,even they have no street to walk safely. And their response to the environment was very negative. Basically the elements from exterior space to interior space should be guaranteed for everyday according to their behavioral characteristics include handicapped. From this study the result shows that the needs of a person should be considered and accepted as an important design problem for improvement our environment.

This paper reviews studies on information searching behavior in process control systems and discusses some implications learned from previous studies for use in human factors studies on nuclear power plants (NPPs) main control rooms (MCRs). Information searching behavior in NPPs depends on expectancy, value, salience, and effort. The first quantitative scanning model developed by Senders for instrument panel monitoring considered bandwidth (change rate) of instruments as a determining factor in scanning behavior. Senders' model was subsequently elaborated by other researchers to account for value in addition to bandwidth. There is also another type of model based on the operator's situation awareness (SA) which has been developed for NPP application. In these SA-based models, situation-event relations or rules on system dynamics are considered the most significant factor forming expectancy. From the review of previous studies it is recommended that, for NPP application, (1) a set of symptomatic information sources including both changed and unchanged symptoms should be considered along with bandwidth as determining factors governing information searching (or visual sampling) behavior; (2) both data-driven monitoring and knowledge-driven monitoring should be considered and balanced in a systematic way; (3) sound models describing mechanisms of cognitive activities during information searching tasks should be developed so as to bridge studies on information searching behavior and design improvement in HMI; (4) the attention-situation awareness (A-SA) modeling approach should be recognized as a promising approach to be examined further; and (5) information displays should be expected to have totally different characteristics in advanced control rooms. Hence much attention should be devoted to information searching behavior including human-machine interface (HMI) design and human cognitive processes.

The objective of this study is to identify the visual function impairment of children with each type of attention deficit hyperactivity disorder(ADHD). The subjects of this study were 49 children diagnosed with ADHD with visual function out of the normal range. The type of ADHD was investigated using the Korean-ADHD Rating Scale and visual function test. The attention deficit type(69.4%) of ADHD was the most common type among children with ADHD with vision problems. Although their overall naked-eye visual acuity was good, about 50% of the subjects showed problems with visual function. For those with the attention deficit type of ADHD, the myopia-related refractive error was high. For those with the hyperactivity type of ADHD, the astigmatism-related refractive error was higher. For those with vergence function disorder, convergence insufficiency was the most common. As there were differences in the visual impairment characteristics of children with different types of ADHD, it is necessary to approach a child's problem behavior through examination and screening for visual function disorders.

This thesis focuses on a study of design science, which is of a disciplinary character. And the purpose of such a study is to suggest a new direction to develop aesthetics through an empirical research into environmental psychol-ogy, human behavior, design thought, and the visual qual-ity of environment. The author of this study, since recognizing the necessi-ty of understanding environmental aesthetics as well as the necessity of aesthetics, has done an elementary study of empirical aesthetes, and then obtained some facts as follows: First, it is possible to analyse the visual characteristics immanent in the interrelations between human and envi-ronment by means of applying both the information the-ory of formal perception and expressional value and the perceptual theory of ecology to environmental aesthetics. Second, formal aesthetics is a science about the form and structure and in the meantime, symbolic aesthetics is a science about the environmental patterns giving pleas-ure to mankind and its associative meanings. Accordingly it is same as providing some aesthetic value to the ob-ject of environment design to apply some empirical data of visual quality to environmental design. Through such a process, users are provided or delivered with diverse, visual effect. In conclusion, environmental aesthetics is worthwhile to study, and its purpose is that it, as a framework of use-ful knowledge to the creation of the environment superi-or in quality, be applied to design.

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.

The characteristics of aquatic light fields are generally reflected in the visual systems of fishes inhabiting them. Therefore, research on light sensitivity of fish is useful to explain the correlation between the visual function and habitat, behavior and distribution of fish. Rockfish is an important species in coastal ecology and also one of the main species for culturing in Korea. To make a contribution on the maintenance of the fish resources and understanding the ecology of the rockfish, the visual spectral sensitivities of the dark-adapted rockfishes were measured in the range of visible light (405~660 nm) using a light source of light-emitting diodes (LEDs). In order to assess electrophysiological response of the fish, the ERGs (electroretinograms) of the dark-adapted rockfishes were recorded on a data logger (12 bits) and a laptop computer. Juvenile (n=5; weight: $20.3{\pm}5.2g$; total length: $10.3{\pm}0.7cm$) and adult (n=5; weight: $87.8{\pm}21.8g$; total length: $18.1{\pm}1.3cm$) rockfishes were used in experiment. The visual threshold of juvenile and adult rockfish were 11.66 (log quanta/$cm^2/s$) and 11.81 (log quanta/$cm^2/s$) in 574 nm, respectively. The peak wavelength of the spectral sensitivity in the dark-adapted juvenile and adult rockfish was commonly 551 nm (series of green color). Collectively, these results demonstrate that the rockfish has suitable visual capabilities for inhabiting coastal water in Korea.

The aim of the present study was to investigate age-related differences in stepping behavior in response to sensory perturbations of postural balance. The participants for this study were 2 healthy elderly adults (mean age=76.0) and 2 younger adults (mean age=25.5). Subjects were asked to step over a 10 cm high obstacle at self-paced speed with the right limb to land on the primary target (normal step length) that is 10 cm in diameter. However, if, during movement, the light was illuminated, then the subject had to step on the secondary target (long step length). It was planned that the onset of the light would be prior to peak Fx of swing limb, between swing peak Fx and swing toe-off, and after swing toe-off. In the younger adults these secondary visual cues were provided at mean times of 240 ms (standard deviation (SD)=11), 402 ms (SD=13), and 476 ms (SD=88) following the movement onset. Corresponding mean times for the healthy elderly were 150 ms (SD=67), 352 ms (SD=39), and 562 ms (SD=115). Results showed great changes in both group and visual cue condition in Fx ground reaction forces and temporal events following the swing toe-off. Swing limb acceleration force (Fx) and stance peak Fx1 was much greater in the young adults compared to the older adults. Both young and older adults increased stance peak Fx2 in the visual cue condition compared to normal stepping. There was no difference in stance peak Fx2 between the visual cue conditions in both groups. Similarly, the time to stance peak Fx2 was much longer for the visual cue condition than for the normal stepping. It was not different between the visual cue conditions in the young adults, but in the elderly mid and late cue was much greater than early cue. In addition, time to stance peak Fx2 and swing and stance time were much longer in the older adults compared to the young adults for the visual cue conditions. These results suggest that unlike young adults, elderly adults did not flexibly modify their responses to unexpected changes in step length while stepping over obstacles.

Today's consumers have the behavior of purchasing that is self-value-centered and distinctly goal-conscious. Because of this trend the new shops that sell well have the characteristics that effectely transfers strong store-image. The starting point of selling is showing. To appeal to the sense of more consumers and to facilitate the act of consumption you should express more surely store and image of merchandise in the limited space of sales room. Especially in the compound living goods store which sell various items of products the role of presenting the whole merchandises attractive and organized is of utmost importance and the interior planning of show rooms and displaying the room according to the actual sales. According to this the goal of this study is to create not only the convenience of purchasing but also distinguished store image through organizing show rooms according to themes as a part of VMD strategy.
