Throughout the history of architecture, sometimes the main focus of design was determined by a particular visual representation method, and other times a particular form of visual representation method was required by perception of a particular architectural issue or an architectural form or idea. That is why the visual representation method of architects becomes an important means of reading the flow of idea and thinking behind architecture. This study is an investigation on the relation between architectural thinking and visual representation method expressed through the conceptual drawings by avant-garde architects of the 1970s and 80s, a period of the emergence of postmodernism. Rather than proving the objective reality regarded important by traditional architectural drawing, attempts are made to express the design concept in which the project has its base. Such interpretation and explanation regarding the concept become the main interest of the drawing. It is not that the architecture itself was not expressed in the contents, but it may not be the main subject of expression in the drawing. The value of architectural drawing recovers its value as an art work in itself, as a means of communication, and as an important conceptual tool in the design process. It can be seen that the visual representation method in postmodern architectural drawings is breaking free of the traditional objective depiction of matter and is changing and developing as a design tool of the architect.

This study investigates the effects of visual texture on color emotion and establishes prediction models for color emotion by both physical color properties and visual texture characteristics. A variety of fabrics including silk, cotton, and flax were colored by digital textile printing according to chromatic hue and tone combinations that are evaluated in terms of color emotion. Subjective visual texture ratings are also obtained for gray-colored same fabrics to those used in color emotion tests. As a result, fabric clusters by visual texture factors showed significant differences in color emotion factors that are primarily affected by physical color properties. Finally prediction models for color emotion factors by both physical color properties and visual texture clusters were established, which has a potential to be used to explain color emotion according to the visual texture characteristics of fabrics.

Visual information retrieval and image databases are very important applications of spatial access methods. The quaries for these applications are visual and based not on exact match but on dubjective similarity. The individual aperations of spatial access methods are much more expensive than those of conventional one-dimensional access methods. Also, because the visual queries are much more complex than textual queries, an efficient processing technique for visual queries is one of the critical requirements in the development of large and scalable image databases. Therefore, efficient translation and execution for the complex visual queries are not less important than those of textual databases. In this paper, we introduce our cognitive and topological studies that are required to process subjective visual queries effectively. Then, we propose an efficient translation and execution techniques for similarity based visual queries by conducting these related studies.

Purpose: This study investigated the relationships of handwriting legibility and perceptual-motor skills, and handwriting speed and perceptual-motor skills. And identified the predictors that most affect the handwriting of preschool children. Methods: Twenty-three typically developing preschool aged children (mean age: 68.61 months, SD=2.04) were selected through the Korean-Denver Developmental Screening Test-2(K-DDST-2). The children were tested with regard to handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Results: First, a significant relationship was not found among handwriting legibility, visual perception, visual-motor integration and fine-motor coordination. Second, a significant relationship was found among handwriting speed, visual perception and fine-motor coordination. Third, stepwise multiple regression analyses showed that general visual perception were significant predictors for handwriting speed. Conclusion: Occupational therapists should evaluate children's visual perception levels utilizing a standardized test, and focus on general visual perception in order to improve handwriting skill(speed). Also, occupational therapists are expected to play an important role in the management and treatment of children's handwriting skills.

As measuring visual behavior by utilize eye-tracker, this study examines whether consumer concentrates on visual attention with certain object and measures visual behavior with fixation number, fixation duration, the first fixation, which are visual attention pattern of consumer about Mannequin, hanger, shelve as props of display advertising effect on clothing store. It has experimental purpose to recognize relationships in terms of regardless, appropriateness, purchase intention. During display of clothing store, first experimental consequence to measure visual behavior on consumer did appear to allocate more cautions than other props. Second, in terms of relationships with regardless, appropriateness, purchase intention from consumer, each fixation pattern about consumer's fixation number, fixation duration, the first fixation was confirmed that there is meaningful correlation with each other. Accordingly, as advertising effect of mannequin makes consumer to concentrate more visually cautious, it is translated that high favor about display product with mannequin has positive role on purchase intention. Also, there is a purpose that higher feasibility on study result provides practical point on clothing store's display marketing strategy of corporation.

This study investigated the correlation between consumer's buying habits and food styling visual elements. Differentiated and original techniques were used to determine whether or not visual elements in tteok menus reflect the aesthetic needs of consumers without altering the nutrition of tteok. The targeted tteok cafes were in Jeonju Hanok Village, which is a tourist attraction in Korea. First, sub-factors of food styling visual elements applied to tteok $caf{\acute{e}}$ menus such as shape, size/volume, color, and texture all had significantly positive effects on customer satisfaction, proving that food styling visual effects applied to tteok $caf{\acute{e}}$ menus have significant effects on customer satisfaction. Second, sub-factors of food styling visual elements applied to tteok $caf{\acute{e}}$ menus all had significantly positive effects on buying habits. Third, customer satisfaction of menus had a significant effect on buying habits, as proven by previous studies. Fourth, the effects of customer satisfaction on the relationship between food styling visual factors applied to tteok $caf{\acute{e}}$ menus and buying habits were investigated.

The purpose of this study was to study visual evaluation by the variation in the location of the belt of skirt and slacks. The results were as follows: 1. The visual evaluation by variation in location of the belt of skirt and slacks were classified by 4 factor: attractive image, horizontal effect, ordinary image, vertical effect. 2. As the study investigated differences by each factor according to a belt location of a skirt and slacks, the attractive image factor showed a bigger difference than any other factors. Especially, the study evaluated that a low location of the belt exhibited a attractive image for a skirt than slacks. 3. 9cm and -3cm or -5cm displayed the slenderest and smallest look respectively for a skirt and slacks in a horizontal visual effect. -1cm, -5cm and -1cm were revealed tallest and longest look respectively for a skirt and slacks in a vertical visual effect. 4. The variation in location of the belt had more effects on a visual image than a visual effect.

The study on the analytical and productive methodolgy of visual culture contents is meaningful because cultural contents are regarded as a national growth industry. The fundamental notion of cultural contents is researched based on the notion of visual culture, and important factors of the fun are analyzed as a creative motive of visual culture contents. So this paper provides anaytical methodologies for the fun in visual culture contents, which are based on semiotic theories of Charles Morris, Roland Barthes and Roman Jakobson. These analytical matrix can be references for the study of the mechanism of fun and the basic theory for using fun effects in the visual culture contents.

Two experiments were carried out to compare the suitability in visual tasks between cathode-ray tube (CRT) and thin film transistor-liquid crystal display (TFT-LCD). In the first experiment, the subjects were requested to detect pre-assigned target words or icons among distracters presented under time-invariant (static) image mode. The subjects' visual performance and fatigue were assessed while carrying out search tasks with dim and bright ambient light conditions. Significant interaction effects were found among displays, task types, and ambient light conditions. Due to visual fatigue, the subjects' accommodative power decreased in the end of task and the degradation was more significant for the CRT users and under bright ambient light. IN the second experiment, the subjects performed information processing task with time-varying road signs at a driving simulator to assess interaction effects between display types and changing speed of dynamic image. The perception time using TFT-TCD was shorter under slow image change while that of CRT was shorter rapid image change. Findings from this study suggest that, to improve visual task performance, users should carefully select their visual display type depending on the task to be performed.

Objective: This study compares two visual occlusion methods for the evaluation of in-vehicle interfaces. Background: Visual occlusion is a visual demand measuring technique which uses periodic vision/occlusion cycle to simulate a driving(or mobile) environment. It has been widely used for the evaluation of in-vehicle interfaces. There are two major implementation methods for this technique: (1) occlusion using PLATO(portable liquid crystal apparatus for tachistoscopic occlusion) goggles; (2) occlusion using a software application on a touchscreen device. Method: An experiment was conducted to examine the visual demand of an in-vehicle interface prototype using the goggle-based and the touchscreen-based occlusion methods. Address input and radio tuning tasks were evaluated in the experiment. Results: The results showed that, for the radio tuning task, there were no significant differences in total shutter open time and resumability ratio between the two occlusionconditions. However, it took longer for the participants to input addresses with the touchscreen-based occlusion. Conclusion & Application: The results suggest that touchscreen-based method could be used as an alternative to traditional, gogglebased visual occlusion especially in less demanding visual tasks such as radio tuning.
