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.

This thesis on the basis of the "Sasang"(the four classification by the physical constitution) that becomes the focus of the public interest in Korea intends to grasp a color image and serve basic materials for the color usage in the interior design planning. It tries to identify the relationship between physical constitution and color. The color planning for experiment plans to be related to Korean traditional color. Analysis result on color and color image to patterns of interior color shows that the physical constitution in measure difference is bigger than sex among the many image evaluation items. Therefore, the interior color preference of Korean is bright hue and tint such as warm and cool color.

This study suggests a method to predict the color appearance of textiles that shifts depending on illumination variations. The suggested method allows the calculations of lightness, chroma, and hue appearance values from the spectral reflectance values of the textile and illuminant. The accuracy of the method was evaluated through numerical and statistical comparisons between the predicted and the measured color appearance values of 24 fabric samples under CIE standard illuminant D65. As a result, there were excellent agreements between the two data sets with the error values close to zero. The predicted color appearance values of 24 samples under two illuminating (color temperature-luminance) conditions, 2700 K-100 cd/㎡ and 6500 K-100 cd/㎡, were then compared to prove the significant effect of illumination on the color appearance of textiles. The color appearance values were also compared with spectrophotometrically measured physical color attributes, that is, true colors of the samples. The physical color attributes of samples were unchanged; however, differences in color appearance under different conditions were generally much larger than the suprathreshold color difference tolerances discussed in the color science literature. Finally, the magnitude of the illumination effect depending on the physical color attributes of samples was also analyzed.

Purpose : The purpose of this study was to investigate the effect of color stimuli on the grip power and the pinch power. Methods : For this experimental study, total 59 healthy college students, who were divided into Red color group and Green color group. Each group was assessed before and after color stimuli(10minutes). Subjects were for using standardized positioning with shoulder adducted and neutrally rotated, elbow flexed at 90 degree and the forearm and wrist in neutral position. Results : All the two groups showed significant differences in the variation of grip power and pinch power under color stimuli(P>.05) but there was no significant variation in grip power and pinch power among groups. Conclusion : This study precedes following study which is focused on the proposal of suitable or appropriate color circumstance for treatment room. Further studies are need with more subjects on long-term outcome.

The purpose of this study was to investigate the effect of age, physical type and job on preference for color and fabric motifs in men's clothing design. Color preference measures consisted of clothing styles painted in CAD. Preference for fabric motifs was assesed by stripe fabrics in size, width and strength. All of the preference measures were devised specifically for this study. Furthermore, items on Hight and Weight for physical type, age and job of subjects were included I the questionnaire. Data were obtained by self-administered questionnaires form 243 men (25-54 years old) in Seoul. Analysis was by chi-square (X2), frequency, and percentage. The results obtained in this study were as follows : 1. Color preference was not affected by age and physical type, Job was related to coordinate color of men's clothing. 2. Preference for width of striped motifs was affected by age and job. 3. Preference for strength of fabric motifs in men's jacket was affected by physical type.

This study was aimed to investigate the effects of visual texture on color emotion and to establish prediction models for color emotion by both physical color properties and visual texture characteristics. A variety of fabrics were printed by digital printer according to hue and tone combinations. Subjective sensation was evaluated in terms of visual texture for fabrics printed in gray whereas color emotion for those in chromatically printed. As results, fabric clusters by visual texture showed significant differences in color emotion factors and the differences were clearer for grayish tone fabrics. Prediction models for color emotion factors by both physical color properties and visual texture clusters were proposed as for all fabrics and grayish ones, respectively.

This study deals with the analysis of color-difference and physical property of anti-corrosion coatings using at inside of concrete tank for drinking water. Because anti-corrosion coatings are effected by chemical attack, color and physical property are changed. So in this study when epoxy resin coatings of 3 types were received chemical attack by Cl- and NaOH, we present the co-relationship between color-difference and bond strength. For this study, we used the colorimetry, which can measure the degree of color difference on surface of materials. As the results, in case of Cl-, color change is appeared, bond strength also is decreased. From this experiment, we could know that color change due to chemical aging has the deep relationship with physical performance(bond strength) materials. further researches are needed.

This research was performed to investigate the physical properties and color appearance of Hanji manufactured using bast fibers dyed separately by two reactive dyes with different colors. The breaking length of color Ha was above 7 km. The fastness was five grade; the use of reactive dyes made the color of the Hanji not to be faded away. The Hanji manufactured by mixing uniformly two types of bast fibers separately dyed showed the mixed color of two different colors. However, the shives showed their original colors, resulted in irregular color patterns all over the sheets. The color of color Hanji with different colors in the front and back side of sheets showed color difference between front and back side of the sheets. Accordingly, the color of the sheet has a reflection from the backside, resulted in Pink. The colors of the Hanji appeared in this study could not be found from the Hanji manufactured by traditional methods.

There are Two new models developed for objective evaluation of fabric color patterns by applying a multiple regression analysis and an adaptive foray-rule-based system. The physical features of fabric color patterns are extracted through digital image processing and the emotional features are collected based on the psychological experiments of Soen[3, 4]. The principle physical features are hue, saturation, intensity and the texture of color patterns. The emotional features arc represented thirteen pairs of adverse adjectives. The multiple regression analyses and the adaptive fuzzy system are used as a tool to analyze the relations between physical and emotional features. As a result, both of the proposed models show competent performance for the approximation and the similar linguistic interpretation to the Soen's psychological experiments.
