${\beta}-Carotene$, vitamin E, and folate contents according to color and species of Capsicum annuum were investigated. In addition, four C. annuum species were cooked by using different methods (boiling, pan-cooking, pan-frying, deep-frying, steaming, roasting, and microwaving), and retention rates of ${\beta}-Carotene$, vitamin E, and folate affected by color and species were evaluated. Weight loss was observed in all paprika and pepper species using all cooking methods. ${\beta}-Carotene$ and folate contents of C. annuum samples were significantly different by color, species, and cooking method (P<0.05), whereas vitamin E contents were not significantly affected by species. ${\beta}-Carotene$, vitamin E, and folate contents (mg/100 g) of raw C. annuum showed ranges of 95.4 (green pepper)~2,441.1 (red pepper), 0.7 (green paprika)~4.2 (red paprika), and 6.2 (green pepper)~148.7 (red pepper). As a result, the highest ${\beta}-Carotene$, vitamin E, and folate contents were detected in deep fried red pepper, roasted red pepper, and boiled red pepper, respectively, among the cooked samples. Retention rates of C. annuum varied by cooking method, resulting in ranges of 77.3% (boiled red pepper)~356.4% (roasted green pepper) for ${\beta}-Carotene$, 2.0% (microwaved red pepper)~789.3% (deep-fried green paprika) for vitamin E, and 20.9% (microwaved red pepper)~445.1% (steamed green pepper) for folate. Over 75% retention rates were observed for ${\beta}-Carotene$, vitamin E, and folate in all samples except for red pepper. However, in red pepper, vitamin E and folate retentions were remarkably lowered by deep frying and micro-waving, resulting in rates of 2.0~32.1%. This study provides information on effective cooking methods for vitamin retention in C. annuum depending on color and species.

This paper describes visual tracking procedure of the underwater mobile robot for nuclear reactor vessel inspection, which is required to find the foreign objects such as loose parts. The yellowish underwater robot body tends to present a big contrast to boron solute cold water of nuclear reactor vessel, tinged with indigo by Cerenkov effect. In this paper, we have found and tracked the positions of underwater mobile robot using the two color information, yellow and indigo. The center coordinates extraction procedures are as follows. The first step is to segment the underwater robot body to cold water with indigo background. From the RGB color components of the entire monitoring image taken with the color CCD camera, we have selected the red color component. In the selected red image, we extracted the positions of the underwater mobile robot using the following process sequences; binarization, labelling, and centroid extraction techniques. In the experiment carried out at the Youngkwang unit 5 nuclear reactor vessel, we have tracked the center positions of the underwater robot submerged near the cold leg and the hot leg way, which is fathomed to 10m deep in depth.

The results of the analysis of dyed rayon fabrics treated with persimmon juice by padding are as follows. Rayon fabrics were dyed repeatedly with persimmon juice by a padding mangle for the development of dyeability. The merits of padding-based dyeing were easier color reproduction (versus traditional hand dyeing) of hard to obtain colors and color fastness to light and laundering. The add on weight increased with the number of padding times, and the color of the dyed fabrics had red-yellow colors with low brightness and high chromatic colors. Properties of fabrics treated with persimmon juice were: $2^{nd}$ level of light resistance, $4^{th}-5^{th}$ perspiration fastness levels, rubbing fastness, and $3^{rd}-4^{th}$ washing fastness levels. Dyed fabrics exposed to UV light have a deep yellow-red color that increased lightness and darken when exposed to sunlight. Rayon fabrics of a treated premordant indicated strong yellow colors, especially fabrics with Fe mordant indicated greenish red-yellow colors. The direction of the weft and warp increased and improved water-repellent qualities that increased with the number of dyeing padding times and persimmon juice; however, there was less anti-crease resistance. In addition, fabrics had good antibacterial activity and deodorization.

In recent, it is said that the trend of LCD is direction to pursue high qualities like as high transmittance, high contrast ratio, wide viewing angle, fast response time, and so on. Especially, it is known that these qualities are essential to large size LCD like as LCD TV and we can realize them through to uniform cell gap and deep black state. Until now, the ball spacer has been used to control of uniform cell gap. However, the existence of ball spacer inside the cell causes the deformation of the liquid crystal molecules and damage to alignment layer. Such a deformation of the liquid crystal causes light-leakage in the dark state, which lowers contrast ratio of the display. Nowadays, this problem has been solved by using Patterned Spacer on Color Filter. but Side Effect just as gravity mura has been induced. In this paper, we studied the mechanism on gravity mura in case of using patterned spacer on color filter.

This study investigates the current status and dyeing properties of various natural indigo powder dyes in the domestic market. Products from India, China, Europe are sold in the market and only a few manufacturers provide recommendation for the method of dyeing and information on the additives. Through the market research and the preliminary investigation on 21 products, 11 were selected for the dyeing experiment which include 3 Indian, 3 Chinese, 2 German, and 1 Pakistani origin indigo reduced powders, and 2 Indian origin dried indigo leaf powder. The two dyeing methods used were the precipitation method and the fresh juice method, both at $10^{\circ}C$, $25^{\circ}C$, and $60^{\circ}C$. Color difference, K/S value, and colorfastness of dyed cotton fabrics were examined. Indian reduced indigo powder showed the highest K/S value, deep dyeing, and the best color fastness. Chinese reduced indigo powder resulted in a more greenish and bluish color. Powders of dried indigo leaves were easy to use but resulted in a pale color due to low dye uptake.

Underwater images usually have various problems, such as the color cast of underwater images due to the attenuation of different lights in water, the darkness of image caused by the lack of light underwater, and the haze effect of underwater images because of the scattering of light. To address the above problems, the channel attention mechanism, strengthen-operate-subtract (SOS) boosting mechanism and gated fusion module are introduced in our paper, based on which, an underwater image recovery network is proposed. First, for the color cast problem of underwater images, the channel attention mechanism is incorporated in our model, which can well alleviate the color cast of underwater images. Second, as for the darkness of underwater images, the similarity between the target underwater image after dehazing and color correcting, and the image output by our model is used as the loss function, so as to increase the brightness of the underwater image. Finally, we employ the SOS boosting module to eliminate the haze effect of underwater images. Moreover, experiments were carried out to evaluate the performance of our model. The qualitative analysis results show that our method can be applied to effectively recover the underwater images, which outperformed most methods for comparison according to various criteria in the quantitative analysis.

The purpose of this study is to provide basic information to improve competitiveness of Korean fashion brands in the Chinese fashion market by taking photos of street styles in Seoul that is the hub of Korean fashion and in Dalian, the northeastern district where Korean fashion brands are launched as a test market China to compare and analyze the clothing colors preferred mostly by young women in their twenties and thirties who have the highest purchasing power. The study methods used literature review and empirical study simultaneously. Dalian and Seoul are two fashion cities in northeast of China and Korea where street fashion was photographed. Clothing colors that were mainly worn by young women in their twenties and thirties were qualitatively analyzed using the photos taken. Color analysis was based on the Munsell Color Order System to grasp general preferences of colors on the basis of previous researches, and color tones were based on the ISCC-NBS System. In order to grasp the basic materials on Seoul, the Korean fashion city and Dalian, the northeastern fashion city in China, street fashion styles of 2010/11 F/W season were compared and analyzed. As a result, black and deep tone PB color appeared most frequently. The vivid and strong tone of R, YR, Y color showed high frequency of clothing colors. For the top wear, women in both areas preferred similar tones in the YR color category and Dalian women preferred vivider and brighter S tones in the R color category. For the bottom wear, women in both areas highly preferred achromatic colors and colors in the PB color category. For bags, women in both areas preferred black and colors in the YR color category. Finally, for the shoes, while women in both areas preferred black in the achromatic color category, they showed different color preferences in the chromatic color category. R color categories were preferred by the women in Seoul and the YR color categories were preferred by the women in Dalian. Conclusively, women in both cities highly preferred achromatic colors especially black for the top and bottom wear, bags, and shoes. It may reflect their desire to look refined and slender through colors. Moreover, continuous and steady research on fashion trends in Seoul and Dalian may have positive effects on Korean fashion businesses that plan to be launched in China, the area of competition for global brands.
