The color of an esthetic restorative material is controlled primarily by thickness of the material and background color. Although the effects of the two factors on the color coordinates of esthetic dental materials have been reported, the mechanism has not been clarified well enough to explain the effects quantitatively. The purpose of this study was to evaluate the effect of thickness and background color on the color of tooth colored restorative materials quantitatively. One hundred sixty samples were fabricated from two commercial light-cured composite resins and two commercial compomers. The color characteristics and changes in the color coordinates were measured by a tristimulus colorimeter (Model TC-6FX, Tokyo Denshoku Co. Japan) using the CIELAB system. The results were as follows: 1. As thickness increased from 1.0 to 4.0mm, values of $L^*$ $a^*$ $b^*$ changed irregulary for white and dentin color background, but showed no obvious difference in color for black background. 2. The colors of composite resins and compomers were significantly influenced by background color. 3. The color difference was recognized even the same shade name in four representative kinds of composite resins and compomers. 4. As thickness changed, values of color difference for same products and same background color showed constancy, but showed difference for different background color.

This study aims to analyze how the color of Korean traditional architecture affects its plasticity. The researcher took (our distant and near photographs of each representative building of each use, measured the colors, and analyzed these using the color perception theory. The results are summarized as follows: 1. When perceiving the entire plasticity of a building, the color of Korean traditional architecture reduces the heavy feeling that may be brought about by the roof's weight, but stresses the solidity of the pillars. This color perception effect displays the visual stability and balanced plastic beauty of the building's facade. 2. When looking at a building up close, the building's color emphasizes the solidity of the major materials used to construct it through a contrast effect, and highlights the characteristics of each building, such as the dignity of its seal engraving, its magnificence, its simplicity, etc. 3. The color of Korean traditional architecture is a major factor that expresses plastic language as it displays topographical level differences and intercepts or opens view through the artificial division of space, etc., according to the building's use.

In this paper, a novel method is proposed using color and pattern information for recognizing some emotions included in a fertile. Here we use 10 Kobayashi emotion to represent emotions. - { romantic, clear, natural, casual, elegant chic, dynamic, classic, dandy, modem } The proposed system is composed of feature extraction and classification. To transform the subjective emotions as physical visual features, we extract representative colors and Patterns from textile. Here, the representative color prototypes are extracted by color quantization method, and patterns exacted by wavelet transform followed by statistical analysis. These exacted features are given as input to the neural network (NN)-based classifiers, which decides whether or not a textile had the corresponding emotion. When assessing the effectiveness of the proposed system with 389 textiles collected from various application domains such as interior, fashion, and artificial ones. The results showed that the proposed method has the precision of 100% and the recall of 99%, thereby it can be used in various textile industries.

The objectives of this study were to investigate the perceptions of Korean female university students for clothing pattern tendency and structural element of clothing pattern image dimension and to find how individual personality type influence the preferred clothing pattern characteristics. For this study, a questionnaire was designed and sent to 600 female university students of Daejeon, Seoul and metropolitan area. The tool used in this study was MBTI(The Myers-Briggs Type Indicator) Form G Korean version and for the analysis of data SPSS 10.0 package were used. 10 representative patterns for this study were floral, dot, stripe, check, animal, abstract & artistic, geometric, vegetable & leaf, paisely, patchwork pattern. The data were analyzed by factor analysis, arithmetic mean, One-Way ANOVA, x²-test. The major findings were as follows: Clothing pattern image dimension perceived by Korean female university students for 10 representative patterns were basic form, deluxe, specialty, and cultural dimension. Among them, basic form and deluxe dimension were major dimensions. In basic form dimension, dot pattern score was high indicating female students perceive it as light, comfortable, clean, cool and simple pattern image. In deluxe dimension, floral pattern scored high and in specialty dimension, abstract and artistic pattern scored high among other pattern image. In cultural dimension, geometric pattern and check pattern scored high. Based on other detailed analysis results, It is concluded that the personality type greatly influence clothing pattern evaluation. For example, in case of color combination of patchwork pattern, there was a difference in color preference depend on a personality type such as sensing(S) or intuition(N). Therefore, sensing personality type preferred adjacent color combination than contrast color combination. Detailed marketing strategy is necessary in planning textile design of merchandise plan.

Movie clothing is what is recreated as a character in work after being worn for actors (or actresses). And it is not added for heightening only fantasy but it acts for heightening only fantasy but it acts for reinforcing the side of character or subject. Especially the clothing in color movie gets to have very psychological effect. Thus Accord-ing to the clothing the effect of the represen-tation style may become large and small. So as to make the gesture or attitude of each character valuable in accordance with the ac-tion and expression of the figure clothing is different from other device essentially One may attain various goals through the color of movie clothing, First movie clothing may show the vogue color of the time and the representative time color, Second the color of movie clothing helps one to able to recognize the socio-econmic position of character easily as the color to symbolize the specific jobs such as nurse soldier and doctor etc. Third the color of movie clothing may show the charcter temperament as to whether one is young or old and whether one has pessi-mistic temperament or one is extrovert or introversive etc. easily. Fourth setting the clothing color of hero as the color to set off helps it easy to distinguish from representation staffs. Fifty the whole color establishment of movie clothing gives help to expressing the at-mosphere of movie. Color is one of the most powerful means that the person in charge of clothing may express the character of movie. He should ex-press the feature of a wearer with the colors of each clothing through showing the lack of taste of characters or hinting the resistant character with the clothing color which is not suitable for situation or the conservative character with suppressed color etc. Thus he (or she) should express the clothing color which is suitable for being able to express each character by analyzing the work whole through script and grasping the character of each character so as to establish the clothing which is suitable for individual character.

The purpose of this study is to establish a model that can quantitatively diagnose personal color. Representative color systems for personal colors have limitations in that it oversimplify personal color diagnosis types or it is difficult to distinguish objective differences between diagnosis types. To develop a brand new color system that enhances this, a PCCS color system capable of logical color was introduced and reclassified based on the four main properties of color. Twenty diagnostic types, which are more diverse than the existing color system were proposed and a quantitative method was used to evaluate the degree of harmony with a subject to find an optimized type of subject. The experimenter's individual competency and subjective intervention were minimized by devising a matrix in which a type suitable for the subject is derived when the coded evaluation result is substituted. Finally a quantitative diagnosis model of personal color consisting of three stages: property diagnosis, coding, and seasonal diagnosis was constructed. It can be seen that this will give diversity, reliability, and accuracy to the existing diagnostic methods.

Emotional awareness is the image of a person is represented by different tendencies. Currently, the emotion computing to objectively evaluate the emotion recognition research is being actively studied. However, existing emotional computing research has many problems to run. First, the non-objective in emotion recognition if it is inaccurate. Second, the correlation between the emotion recognition is unclear points. So to test the regularity of image sensitivity to the need of the present study is to control emotions in the computing system. In addition, the screen number of the emotion recognized for the purpose of this study, applying the method of objective image emotional computing system and compared with a similar degree of emotion of the person. The key features of the image emotional computing system calculates the emotion recognized as numbered digital form. And to study the background of emotion computing is a key advantage of the effect of the James A. Russell for digitization of emotion (Core Affect). Pleasure emotions about the core axis (X axis) of pleasure and displeasure, tension (Y-axis) axis of tension and relaxation of emotion, emotion is applied to the computing research. Emotional axis with associated representative sensibility very happy, excited, elated, happy, contentment, calm, relaxing, quiet, tired, helpless, depressed, sad, angry, stress, anxiety, pieces 16 of tense emotional separated by a sensibility ComputingIt applies. Course of the present study is to use the color of the color key elements of the image computing formula sensitivity, brightness, and saturation applied to the sensitivity property elements. Property and calculating the rate sensitivity factors are applied to the importance weight, measured by free-level sensitivity score (X-axis) and the tension (Y-axis). Emotion won again expanded on the basis of emotion crossed point, and included a representative selection in Sensibility size of the top five ranking representative of the main emotion. In addition, measuring the emotional image of a person with 16 representative emotional score, and separated by a representative of the top five senses. Compare the main representative of the main representatives of Emotion and Sensibility people aware of the sensitivity of the results to verify the similarity degree computing emotion emotional emotions depending on the number of representative matches. The emotional similarity computing results represent the average concordance rate of major sensitivity was 51%, representing 2.5 sensibilities were consistent with the person's emotion recognition. Similar measures were the degree of emotion computing calculation and emotion recognition in this study who were given the objective criteria of the sensitivity calculation. Future research will need to be maintained weight room and the study of the emotional equation of a higher concordance rate improved.

This study is to understand the characteristics of women's Hanbok fashion in the modern Korea by investigating the features of colors and color arrangements of remaining relics. The summary of findings from the researches and analysis from over 1840 pieces of Hanbok relics in modern Korea are as follows: First, since western-style cloth were introduced and utilized for Hanbok from 1960, the number of colors have drastically increased. However, the most commonly used colors and parts throughout all the periods remained the same. These are Y, R and white colors for Jeogori and Y, R and PB colors for Chima. And, as for the representative color of each of the six periods, significant changes of color were found Jeogori in the 1960~1970s. While no clear color changes were found in the period prior to the 1960s and after the 1980s. Secondly, as for the color tones, although the high luminosity-low chroma were generally used over the periods, it was observed that various colors of low luminosity-high chroma began to be used from 1960 and so Jeogori became more colorful. And lastly, Y and white color were taking up the highest percentage in the solid color arrangement. When composing 2 colors, the Y tone color dominants with R tone as sub-color was the most prevalent, and when 3 and 4 colors were combined, the extra color were increasingly seen in the upper garment cuff and collar so that the arrangement of different colors increased the aesthetic symbols when combined with the colors of the Chima.
