  • As the competition of city design from various municipals recently, color guidelines are continuously established. But the contents of color guidelines are differing from one municipal to the other, It has doubts on its effectiveness. Thus, the objective of this researchis to investigate municipals' color guidelines in order to apprehend the characteristics and differences among each other. In order to do this, the research will collect color guidelines of 5 different cities and 2 different districts. Then, by organizing tables for different characteristics of contents, the research will attempt to identify the difference between municipals. The conclusion of such research is as follows. First, basic contents of color guidelines are composed with planning, proposing and managing stages. Furthermore its objective, target subject, detailed guidelines and exemplary cases were common. Second, the contents of color guidelines of municipals were vastly differing from each other in respect to the size of the cities or the objectives of its application. Third, color guideline contents of the city of Seoul, Sejong city, and Chung-ra district are composed rather reliably while that of the city of Inchun, and Sung-buk district were lacking considerably in terms of up-to-date survey of environment, color proposal, and managing policy in comparison to other municipals. In conclusion, there is a strong necessity for standardization of establishment or form of the color guidelines. Furthermore, measures for proper adjustment in respect to the size of a municipal or its purpose should be arranged adequately.

  • When evaluating the quality of images and displays, it is important to combine the characteristics as perceived by the human visual system and measured by equipment using subjective and objective methods, respectively. In the case of objective methods, the quality of a display is measured using colorimetric or radiometric devices according to existing standards covering the color temperature, gamut size, gamma characteristic, and device characterization. Meanwhile, subjective methods assess the quality of an image using the human visual system based on a comparison with a reference or counterpart using such metrics as the sharpness, noise, contrast, saturation, and color accuracy. Objective and subjective methods are usually used together in comparison, as ultimately it is observers watching images on a display. In addition to existing objective methods, a new image quality metric is also introduced as regards the JPEG compression ratio that is reflected in the relationship between the gamut size and the color fidelity in CIELAB color space.

  • The principal objective of this research is to evaluate the laboratory mechanical characteristics of color asphalt binders and mixtures. The dynamic shear rheometer (DSR) tests were performed to analyze the viscous and elastic behavior of asphalt binders. Various tests were also conducted to investigate the laboratory performance characteristics of color asphalt mixtures. The test results revealed that the values of $G^*$ and ${\delta}$ of modified color binders were higher than those of the conventional binders at low temperatures. These results are expected to increase the thermal cracking resistance of asphalt mixtures at low temperatures. It should be noted that the color asphalt mixtures with modified asphalt binder can be widely used as a common pavement material with a proper mix design.

  • The main objective of this research was to understand the characteristics of separation color coordination of contemporary female fashion through the analysis of 'pre-a-porter Collections' of four collections (i. e. cities) - Paris, Milan, New York, London - from the periods of 2004 S/S to 2008/9 A/W. The data collection of 265 was done by reviewing 'pre-a-porter Collections' magazine and total 265 observations were made. Statistical analysis of frequency and also qualitative interpretation of separation color coordination characteristics were completed. The main findings were; (1) In separation color coordination of contemporary women's fashion collections, there were three main types of color scheme which were classified into seven detailed categories of color combination. First was the achromatic color & one chromatic separation color scheme which was classified into four categories of - black & white, black & grey, white & grey, and grey & grey - color combination. Second was the chromatic colors & one achromatic separation color scheme which classified into two categories of achromatic & chromatic color & one achromatic separation color combination, and chromatic colors & one achromatic separation color combination. Third was chromatic colors and one chromatic separation color combination. (2) The achromatic colors and one chromatic separation color scheme showed two phases of reinforcing the strong and modern image, or softening the hard and dull image of achromatic color combination. In color schemes which used more than two chromatic colors, the separation color frequently converted the tedious and monotonous fashion image, which caused by identical or similarity in color or tone harmony, into more attractive and interesting. (3) In conclusion, through the various use and coordination of various color schemes, color harmony and separation colors, the separation color coordination in contemporary female fashion has been suggested the effective way of color combination which can lead the visual pleasure and the vitality along with the unity and the harmony. This characteristics can create various images and visual diversity for fashion. The types and the use of color scheme and separation color showed different trends in four collections.

  • Retinex-based image enhancement is a technique that utilizes the property that the human visual characteristics are sensitive to the difference from the surrounding pixel value rather than the pixel value itself. These Retinex-based algorithms show different characteristics of the improved image depending on the applied color space or gamma correction. In this paper, we set eight different experimental conditions according to the application of color space and gamma correction, and analyze the objective and subjective performance of each Retinex based image enhancement algorithm and apply it to the implementation of Retinex based algorithm. In the case of gamma correction, quantitative low entropy images and low contrast images are obtained. The application of Retinex technique in HSI color space rather than RGB color space is found to be high in overall subjective image quality as well as maintaining color.

The data was collected by reviewing 'pre-a-porter Collections' magazine and total 677 observations were made. Statistical analysis of frequency and also qualitative interpretation of achromatic & chromatic color coordination characteristics were completed. The main findings were; (1) The achromatic & chromatic color coordination was identified as one of most used color coordination in contmeporary women's fashion collections. (2) Black and white mainly used for achromatic color, and brown used the most often, then followed by blue, red, yellow, green and the others for chromatic color in achromatic & chromatic coordination of contmeporary women's fashion collections. (3) The characteristics of achromatic & chromatic color coordination of modern women's fashion collections from 2002 S/S to 2006/07 A/W showed various images according to chromatic colors and tone variation. The combination of achromaticand brown color variations produced an intelligent and sophisticated image. The soft or light chromatic color and chromatic color combination projected soft, feminine and subtle feeling, while the combination of vivid or strong chromatic color and achromatic color projected a clean and strong feeling through contrasting tones of clear and bright colors. The chromatic color of deep or dark tone and black combination demonstrated supernatural and gloomy image. (4)In all four collections, Paris showed most use of two color coordination and then followed by Milan, N.Y, and London. N.Y showed higher rate of using achromatic & chromatic color coordination, and then followed by Paris, London and Milan.

  • The main objective of this research is to investigate the color coordination types and their characteristics of contemporary female fashion by reviewing 'pre-a-porter Collections' of four collections (i.e., cities) - Paris, Milan, New York, London - from the periods of 2000 S/S to 2002/3 A/W. Through the review of various books and articles written on the subject, the color coordination types and their characteristics were categorized and defined. The data was collected by reviewing 'pre-a-porter Collections' magazine and total 4,269 observations were made. These in turn were categorized into eight color coordination and three color tone categories through the content analysis. Frequency analysis was used to analyse the data. The findings are as follows; First of all, there were 8 observable color coordination categories in contemporary women's fashion. The most used color coordination was chromatic & achromatic color coordination. It was followed by chromatic identical, and then by achromatic identical color coordination. These three color coordinations were the majority, comprizing 73.4% of the total. The rest were in the order of complementary, gradation, similarity, accent. And the most used tone type was contrasting tone and followed by similar and identical. Next, the analysis of each coordination categories shows that; The chromatic identical coordination focused on presenting its own unity or break it using the contrasting color tone. Meanwhile, the achromatic identical coordination project a clean and strong feeling through black and white combination or a subtle feeling through the different material combination. The chromatic & achromatic coordination showed strong colors and contrasting tones of clear and bright colors. Meanwhile, the characteristics of complementary coordinations are that these coordinations seem to free the colors and show the subtle changes in tones very clearly. The gradation coordination was used to create a cool and lively feeling. Next, the similarity coordination seems to create feminine and warm feeling by taking advantage of similar color feelings, often through the use of warm to warm, cool to cool color matching. Lastly, the accent coordination, through the use of contrasting tones emphasizes the differences in colors, while separation coordination mostly uses black and white on various color coordinations.

  • The principal objective of this study was to evaluate the quality characteristics of jelly prepared with five different levels(0, 0.5, 1.0, 1.5, and 2.0%) of black garlic concentrate(BG1-BG4). We conducted the pH, sugar content, Hunter's color value, mechanical characteristics, and a sensory evaluation analysis of black garlic jelly. The more black garlic concentrate increased, the more the sugar content of the black garlic jelly increased(p<0.05). In terms of color, lightness(L) and yellowness(b) decreased as the black garlic concentrate increased, while redness(a) increased. With regard to the mechanical properties of the black garlic jelly samples, the higher the score of hardness, gumminess, and chewiness significantly increased(p<0.05). In color, flavor, texture and overall quality, the score of jelly with 1.0% black garlic concentrate(BG2) increased most of the all.

  • The main objective of this research was to understand the characteristics of contrast color coordination through the analysis of modern woman fashion color coordination as they appear in the 'Collections' from '04 SS to '09/'10 AW. Data collection of 122 was done through review of '$pr{\hat{e}}t$-$\grave{a}$-porter Collections' of four cities; Milan, London, New York, Paris. Statistical analysis of frequency and qualitative interpretation of contrast color coordination characteristics were completed. The main findings were as follows; (1) The combined color type of 'red+blue' and 'yellow+blue' were the most frequently appeared in the same ratio, and followed by 'green+violet', 'red+yellow', 'green+orange', and 'orange+violet'. The contrast tone showed the most, and followed by the similarity and identity, and the type of tone harmony used differently according to the type of contrasting color combination. (2) The general characteristics of contrasting color harmony were as follows,; Some contrasting colors looked harmonious when used light colors and the contrast between light and dull colors which made the hues even more harmonious. Also combinations of dull colors which work well with other dull colors or vivid colors. Light & vivid color or light & dark color, however, often showed too much contrast and using two contrasting vivid colors presented awkward and restless look. When used one vivid color and one dark color, a little easier to looked at, but still not particularly elegance or effectively harmonious. (3) The types of contrasting color harmony showed some differences between seasons. Contrasting color harmony showed more frequently in the S/S collections than in A/W collections.

  • The main objective of this research was to understand the characteristics of identical color coordination through the analysis of modern female fashion color coordination as they appear in the 'Collections'. Data collection of 2026 was done through review of '$pr\hat{e}t-\grave{a}$-porter Collections' of four cities; Milan, London, New York, Paris. Lastly, statistical analysis of frequency and $X^2$-test and also qualitative interpretation of identical color coordination characteristics were completed. The main findings were; The color coordination of modern women's fashion produces a unified theme, or monochromatic harmony, through the use and coordination of identical colors. The clear contrast of tones portrays a strong image especially in achromatic color coordination, and through the use of texture variation, monochromatic color coordination becomes even more compelling. The tone variation, observed most often in monochromatic color coordination was the black and white contrast, which enhances the simplicity and clarity. Within chromatic color combinations, tone on tone color coordination was achieved by varying brightness. Furthermore, the observation of Faux Camaeu indicates that the coordination of different textures is used often in identical color coordination. While achromatic colors can lead to a hard and rough feeling, it also is compensated through the use of varying textures. In addition, adding variety of textures can add subtle interests to the simplicity of white. Lastly, in all four collections, the chromatic identical color coordination was found more frequently than the achromatic. In Paris, N.Y. & London, the chromatic identical coordination was used more often than chromatic. Milan showed most use of achromatic coordination. The use of the tones showed similar trends in all four collections, with contrasting tone being used most often, followed by similar and identical tones.
