Among the formative elements, color and form are the most critical elements that can capture a person's perspective. Companies are concentrating on developing visual perception-oriented products by accommodating the diverse needs of consumers, where the emotional factor plays as an important design consideration. Accordingly, the visual perception reaction of consumers was analyzed through a questionnaire focusing on color and form. The result finds that, when Ernst Gombrich (1909-2001) perceives objects in questionnaires related to personal preferences for color and form, humans do not rely solely on the eyes, but describes with the knowledge diagram through that knowledge. In doing so, the knowledge that we already know plays a part to describe the object. In addition, colors and forms are recognized by combining the social and cultural information experiences of the perceiver with the learned knowledge. In the future studies that define the interrelationships of the formative elements should be continued through the analysis of more complex and clear visual perception characteristics of the formative elements.

The objective of this study is to review the expressive effect of fashion illustrations and to enlarge its expressive range by analysing the correlations between fashion illustrations and surrealistic expressive characteristics. The results are as follows. The surrealistic expressive methods of fashion illustration such as depaysement and automatism have been used by many foreign and domestic fashion illustrators. I think that these methods reinforce the subjective aspect of expressive effects and enlarge the transmitting function of fashion message. The elements of expression are divided into color, texture, shape/form and space. Subjective colors rather than natural colors are used for the surrealistic expressive effect of color in fashion illustrations, and illusion of space is expressed by the change of brightness. The surrealistic expressive effect in fashion illustrations distorted the experience of factual texture and disturbed the visual texture. The use of tactile texture presented strange effects perspectively. The objects of shape in fashion illustrations were mainly human body. The form of human body presents reconstituted and reinterpreted figure by transformation or distortion according to the intention of the artist rather than realistic and physical form. In fashion illustration, the transformation of the human body itself whose body parts get separated, superposition of exterior material and human body, and the distortion of human body by the change are done. Space is where background and shapes are inter-penetrated because they are ambiguous and untransparent, and where all are in disorder and unbalance. The method of projection uses distance perspective, multiple perspective and amplified perspective representation, and forms a psychological space feeling. And I think the use of surrealistic expressive methods are very useful for the subjective sensitiveness and the transmission of a fashion message, and presents a possibility to develop a new expressive method.

This study investigated the colors of the costumes and backgrounds of characters in the films "Thirst" and "Mother" from an integrated perspective. As a study method, ten scenes per film, which contained the characters and backgrounds from the start to the end of the DVDs of "Thirst" and "Mother" were examined. For integrated color analysis of the costumes and backgrounds, the colors of the captured scenes were simplified to extract representative colors, and then color palettes were presented according to the ratio of area. The colors of costumes were analyzed by recognition through the eyes based on the I.R.I. Hue and Tone 120. Furthermore, the color images of the two films were analyzed using the I.R.I. adjective image scales and the I.R.I. color image scales. The colors of the film "Thirst" were generally low in brightness and high in chroma. They are characterized by dark, gloomy toned-down background in the first half, highly chromatic vivid background in the second half, and the contrast of purple blue colors and red colors. The colors of the film "Mother" are characterized by complementary colors between background and costume colors, and various tones of blue and green colors. From the aspect of color tones, they were relatively high in brightness compared to the film "Thirst" but low in chroma. On the I.R.I. adjective image scale, contrasting adjectives were extracted simultaneously from the film "Thirst" as the adjectives were evenly distributed at hard, dynamic and static, whereas the adjectives extracted from the film "Mother" were distributed at hard and statistic. On the I.R.I. color image scale, both films were located at hard, but the film "Thirst" was located at dynamic whereas the film "Mother" was located at static.

The purpose of this study was to analyze the characteristics of Korean costume colors according to the diachronic stages of culture(Chosun dynasty, Modern times, Present age) and to interpretate the meanings of costume colors as a cultural code. To examine the color characteristics according to the cultural change, the quantitative analysis and the qualitative analysis were used. For the quantitative analysis 1535 color samples were collected and for the qualitative analysis on the sensitive aspect of Korean costume color, 340 color names were collected. The results of this study as follows; 1.'Red' and 'Blue' were preferred throughout the periods. In Chosun dynasty, the higher saturation of 'Red' and 'Blue', its symbolic meanings were more emphasized. 2. In the Modern times, 'Pink' was more distinctive than 'Red'. 'Pink' meant that the ecdysis of the traditional view of color. 3.'Yellow' of the low Saturation was used frequently in Chosun dynasty but in the Modern times, the use of 'Yellow' increased and the high saturation were used. In the Present age, the frequency of 'Yellow' was reduced relating to the increasing use of 'Brown'. 4.'Neutral Color' has changed according to the diachronic stages of the culture. 'Black' was increased and had a big meaning in the cultural aspect of the Modern times. In the Present age, 'Gray' and 'grayish colors' were increased related to Technology, Metals and High rise buildings.

Dresses reflecting human aesthetic consciousness are used as a way of expressing the inner desire of human beings. The desire to attract the opposite sex through sexual appeal among the human inner desires is the one innate characteristic that all human beings have. We may say that the $See-through$ look emphasizes a sense of softness and femininity by exposing the skin and expresses bodily beauty by way of using see-through cloth. It is a fashion style that can express sexual appeal and eroticism of female most effectively. In this study, after observing the motivation of dress wearing and $See-through$ look in the perspective of bodily concept and eroticism, colors of $See-through$ look shown in the $Pret-a-Porter$ Paris S/S collection from 2006 and 2007, a fashion style expressing eroticism was newly re-analyzed as romanticism and glam look particularly in 60, 80s compared with other times were re-created and evaluated. As a result of analyzing colors of the $See-through$ look, Yellow Red(close to skin color) was revealed to be the highest( 31.3%), followed by Red(9%), Purple Blue(7.2%), Yellow(7.2%), Purple(5.4%), respectively and in terms of color tone, pale and gray tones that have a sense of femininity and softness was revealed to the highest(20%) followed by ltg(11%) and dkg(9%). We may find the meaning of this study in analyzing colors of the $See-through$ look, and the typical look of eroticism, which has never been tried before. It is required to identify chronological color features of the $See-through$ look and the diversified characteristics of skin colors expressed in them to prepare useful data by which a sense of the $See-through$ look can be utilized for color coordination through the relationship between skin tone and dress by pursuing a more detailed method based on the result of this study.

We have studied the radial g-r color gradients of early-type galaxies in the Sloan Digital Sky Survey (SDSS) DR6 in the redshift range 0.00 < z < 0.06. The color profiles of ~30 per cent of the galaxies in this sample show positive color gradients (centers being bluer). These positive gradient galaxies often show strong $H\beta$ absorption line strengths or emission line ratios that are consistent with star-forming populations. Combining the optical data with Galaxy Evolution Explorer (GALEX) UV photometry, we find that all positive gradient galaxies show blue UV-optical colors. They also exhibit a tendency of having a lower stellar velocity dispersion. Positive gradient galaxies tend to live in lower density regions than negative gradient galaxies and are likely to have a late-type companion galaxy. On the other hand, massive early-type galaxies show negative color gradients. A simplistic population analysis shows that these positive color gradients are visible only for half a billion years after a star burst. Although the effective radius decreases and mean surface brightness increases due to this centrally concentrated star formation, the positions of the positive gradient galaxies on the fundamental plane cannot be reproduced by any amount of recent star formation. Instead it required a lower velocity dispersion.

Thermal spray technology has been used in many industrial application. Especially, thermal spray coating have been employed with the purposes of achieving better resistances in abrasion, heat and corrosion. In the previous studies on the thermal spray coating, thermal spray characteristics from the perspective of combustion engineering have not been investigated sufficiently, while the material characteristics of the coated substrates have been investigated widely. In this study, the effect of spray particles on the flame behavior was experimentally investigated. The amount of the injected particles was measured using the light scattering method and the temperature of the particles was estimated using a two-color method. Various flame-spray interactions were observed and it was found that the high temperature zone near the flame is elongated by particles density. Based on these results, the applicability of the light scattering method and the two-color method was discussed.

Recent observations reveal that some early-type galaxies show a color-magnitude relation of blue globular clusters (GCs) in the color-magnitude diagrams, which is referred to as 'blue tilt'. This phenomenon is interpreted as a mass-metallicity relation -- metallicities of blue GCs increase with increasing mass, and thus provides a crucial clue to the chemical enrichment processes of GCs as a function of their mass. However, some galaxies show 'non-tilt' or even 'reverse blue tilt' on the blue GC sequence, and thus the origin of blue tilt still remains a puzzle. In this study, we put forward the theoretical explanation for the phenomenon and discuss its implications towards galaxy formation scenarios.
