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 purpose of this study is to suggest objective basic data for environmental resource planning through the evaluation of the visual quality by GIS. For this, Landscape information system have been made up of topographical and superficial information and landscape values of Cheju Island have been evaluated by using Grass 4.1, degree of visual preferences have been measured mainly by questionnaires and finally these data have been analyzed by using the correlation. Result of this study can be summarized as fellows, in the landscape value, remarkable views play a role as the dominant landscape information. Also, LCPs including various, successive view or a lot of visibility amount have high Landscape value. Therefore, it is important to management landscape which can preserve values of landscape elements through the creation of visibility area. In the visual preference, remarkable scenes play a part as a dominant factor. Also, LCPs including a wide field of vision or successive view have high visual preference. Therefore, it is proved that the visual preference is related to a field of vision and remarkable scenes. Finally, these data have been analyzed by using the regression, in order to verify the method. The result is that a R\sup 2\ is 0.715. It means that correlation is significant at the 0.01 level. In conclusion, the results of this study reveal that visual preference has been evaluated by aesthetic variables and landscape values have been evaluated by GIS. And visual preference and landscape values are closely correlated. In other words, it is possible to evaluate the aesthetic value by physical variable. The method of evaluationi is used in Cheju Island, and it will be possible to apply this method to other places. And this method can be applied to other places by special quality and landscape informatioin system, made up of landscape elements. Also, it will be possible to keep up management and applicatioin that is evaluated by GIS and computer program. Recently, there is a tendency tat visual and aesthetic approach, based on planners' experiences and intuitioin is gradually changed to the scientific approach, based on a objective data. Therefore, it is important that the measuring system is based on objective data which are concerned with a special quality of landscape. It is also significant that the environmental planning is based on a spatial image of physical environment and major landscape elements.

Fashion is a product of form expressing the socio-cultural mood and aesthetic value of an age. Owing to development of the mass media and diversification of arts under the influence of post-modernism in the 20th century, fashion has been more briskly expressed to be presented to the people. With such basic conceptions in mind, this study was aimed at reviewing the fashion photography as visual medium. To this end, visual narrative techniques were analyzed and thereupon, Philip-Lorca diCorcia's fashion photography was examined. This study reviews such visual narrative techniques by dividing into visual and non-visual elements and thereby, examines the three-fold aspects of fashion photography expressions : Representative Level, Ground Level and Context Level. Also this study focuses on Philip-Lorca diCorcia's fashion photography in 'W magazine' which features portfolio form. This study analyzed the visual narratives shown in fashion photography and thereby, expand in diverse ways the fixed images of the conventional fashion photography commercials featuring beautiful models and exquisite costumes, and additionally, determined that fashion photography must be a kind of expression tool which could express not only the simple fashion but also the socio-psychological elements inherent in fashion.

In this paper, we propose an efficient and effective selective protection scheme to SVC that exploit the propagation of protection effect by protecting significant frames that can give the maximum visual quality degradation. We model SVC dependency coding structure as a directed acyclic graph which is characterized with an estimated visual quality value as the attribute at each node. The estimated visual quality is calculated by using our model based on the proportions of intra- and inter-predicted MBs, amounts of residual, and estimated visual quality of reference frames. The proposed selective protection scheme traverses the graph to find optimal protection paths that can give maximum visual quality degradation. Experimental results show that the proposed selective protection scheme reduces the required number of frames to be protected by 46.02% compared to the whole protection scheme and 27.56% compared to the layered protection scheme.

The walls of art museums become the background of exhibits, and they form a unit space depending on the of each exhibit. In addition, the walls are configured and presented depending on the rhythm of space, or the structure of an axis. In this study, according to the axis composed for each unit space, the presentation methods of walls were classified as follows: The central type, the skewed type, the crossed type, the one-side corridor type, and the two-way corridor type. By analyzing visual configurations formed by the arrangement of each unit space, the value and the hierarchy of walls are discussed To analyze the classified types with the physical change of unit space, the factors of visual integration, connectivity, depth, and visual axis are compared, and various configurations of walls and space change are applied.

Applying the theory of physiology and control systems, the visual system was studied as a regulator of impining light. The characteristics function of visual system is mainly analysed by spato-temporal characteristics based upon Enroth's model, Broca-Sulzer phenomenon and Mach effect. Some aims of this paper are as follows. (1) In order to get the excitatory and inhibitory potential of the intermediated cell layer in the retina, the exponential value, {exp(FM/kT)- $I_{mn}$ } is caculated based on the physiological theory in neuro-phenomena. (2) To show the visual characteristics by analog simulation for generating stimulus waveforms and analysis, the visual adaptation was recorded as electrical stimulation in the form of step functions. Furthermore, ti is shown that the above experimental data agrees satisfactorily with the theoretical (psychophysiological) values. This study is expected to lead to further studies concerned with human observer and human operator in control and especially pattern recognition systems.stems.

In this paper, we address the problem of controlling an end-effector to track and grab a moving target using the visual servoing technique. A visual servo mechanism based on the image-based servoing principle, is proposed by using visual feedback to control an end-effector without calibrated robot and camera models. Firstly, we consider the control problem as a nonlinear least squares optimization and update the joint angles through the Taylor Series Expansion. And to track a moving target in real time, the Jacobian estimation scheme(Dynamic Broyden's Method) is used to estimate the combined robot and image Jacobian. Using this algorithm, we can drive the objective function value to a neighborhood of zero. To show the effectiveness of the proposed algorithm, simulation results for a six degree of freedom robot are presented.

In this study, a questionnaire was developed to assess error search and correction tasks, and an analysis was performed on the accuracy of the tasks and the time required for their completion in order to identify the effects of LED light source illumination on visual performance according to changes in a predicted mean vote(PMV) thermal environment. In addition, a subjective evaluation was performed by conducting a survey on the level of visual fatigue experienced during the tasks. In the experiment, four types of PMV thermal environments were established according to PMV values in the temperature range of $(17{\pm}1-29{\pm}1)^{\circ}C$ and the humidity range of $(50{\pm}5-60{\pm}5)%$, and the LED light source illumination was divided into three types: 400lx, 700lx, and 1000lx. The experimental results confirmed that the accuracy of the error search(LED p value=0.058, PMV*LED p value=0.083) and correction tasks and the time required(LED p value=0.004, PMV p value=0.000) for their completion were affected by changes in both the PMV thermal environment and the LED light source illumination, whereas a significant difference in visual fatigue was observed only in the PMV thermal environment(p value=0.003).

The goal of this research is a visual and auditory tool development enabling designers to have the same emotional value with users in the process of user centered design. Through the research, we intend to show the aid measure for making cognitive gaps narrow between users and designer in the process of transforming and understanding the emotional needs as a verbal image. because In the business practice of design, most of tools and techniques for assessment and analysis of emotional needs are those used usually in the marketing fields. So the information generated and transformed from users to designers have a form of physical words. When the designer's understanding of the emotional needs is considered as a product mediated communication process, the morphologic and cognitive information gaps become obvious. This difference could be a false basis in designing with emotional user needs. So the alternative needs assessment sub-tools of visual and auditory information form was embodied mainly for designer's cognitive gaps and inter-cultural emotional needs assessment. As the method of embodiment, Firstly, adjectives related to emotion were classified in their cognitive dimension. Secondly, visual and auditory data were extracted, and then the relativity verified. Finally, the practicality and effectiveness were tested through the database generation. In view of the results so far achieved, 1. We could find being of the big information cognitive gaps in the verbal assessment of emotional needs between designers and users. 2. With the visual and auditory assessment tool, we could make the big cognitive gaps narrower than we expected. 3. Also, we could find the chance that the fidelity, recognition, and friendliness of design for emotional user needs would become better.
