FSC(Field Sequential Color) LCD has high efficiency, high brightness and color saturation due to 3 times aperture larger than conventional LCD. However it is well known that color break-up (CBU) and color interference are hot issue need to be solved. We propose a novel sequential driving method with edge-lit light guide composed of $16{\times}15$ blocks to reduce CBU and color interference. The experimental results show not only suppression of CBU but also the side effects are minimized.

An object color can be seen differently under the various outer illuminants. However, human visual system has color constancy that the object color can be seen constantly under the different outer illuminants. When the viewer watches TV under specific outer illuminants, he perceives distorted color due to the emitting spectrum of outer illuminants as well as the radiation of CPT itself. Namely, when the outer illuminants such as fluorescent and incandescent lamps incident on CPT, brightness, saturation, hue, and contrast on color pictures are changed, he perceives distorted color from the original color. In this paper color enhancement algorithm based on light intensity and outer light decision function using RGB sensor was proposed. The implemented TV of proposed algorithm has higher visual quality at the view point of human visual system and more vivid than that of conventional color TV.

색채는 디자인 요소에 있어서 감각적이며 감성적인 동시에 시각적으로 우선시 되는 비언어적 상징이기도 하다. 제품의 선택에 있어서 소비자에게 우선되어지는 중요한 요소이고, 브랜드에 있어서 차별화된 전략 및 일관된 통합성을 주는 상징이 되기도 한다. 광고에서 색채는 장기적인 브랜드 아이덴티티(identity) 측면뿐만 아니라 제품의 이미지와 광고의 컨셉을 표현하는 중요한 도구이다. 본 논문의 주제는 광고 크리에이티브의 발전을 위해 승용차 영상광고의 주도적 색채를 분석하였다. 분석결과 2000cc급이하 경 소형승용차 광고의 색채적용은 명도와 채도가 높고 밝은 분위기로 권위보다는 개인의 개성을 중시, 파스텔조의 색을 선호하는 것으로 나타났다. 반면, 2000cc급 이상의 중 대형승용차 광고는 전반적으로 명도와 채도가 낮고 어두운 색채가 대세를 이루고 있는 경향을 볼 수 있다. 경 소형승용차 광고는 실용적 가치를 중시하는 제품외형에 초점을 맞추었고, 중 대형승용차 광고는 상징적 이미지에 초점을 맞추어 광고표현을 하는 차이를 느낄 수 있다. 광고에 사용되는 색채는 곧 소비자의 감성을 대변하는 것이다. 영상광고에서 소구 대상이 누구냐에 따라서, 또한 어떤 상품이냐에 따라서 색채의 컨셉이 설정이 되어야 하며, 또 그에 따른 색채에 의한 감성을 파악하여 광고 전략에 맞게 활용될 때 브랜드와 제품의 가치를 높일 수 있다.

In the era of the 4th Industrial Revolution, not only artificial intelligence, big data, robots, and biotechnology, but also cultural industries that require human creativity will lead. Among the cultural industries, the animation industry has high industrial utilization value due to its high connection with other industries. Among them, animation characters play the most important role as the subject leading the story of animation. In particular, the villain character not only serves as a medium for the main character to lead the story, but also captivates the audience with a different presence from the main character, adding to the fun and completeness of the animation. These characters consist of visual elements such as form and color, of which color is a tool that effectively conveys the character's personality and role to the audience, and is the first visual element to be considered in delicately describing the character's emotions and the relationship between characters. Therefore, this study attempts to analyze the color of the villain character. To this end, we will select eight Disney animations to derive the characteristics of the villain character's color by analyzing the color, value, chroma, and color association of the colors used in the Disney villain character. As a result of the analysis, the colors mainly used by Disney to convey the villain's image were red (R) and Orange (YR), and there was no difference depending on the times or animation production methods. Second, the brightness of Disney villain characters appeared to be the same medium/famous regardless of the times and production methods, and the frequency of use of high brightness was very low. In terms of saturation, the frequency of use of high and low saturation was high. Third, blackish (Bk), Strong (S), dull (Dl), and deep (Dp) tones were mainly used for tones. In particular, in recent 3D animations than previously produced 2D animations, the use of low chroma and the high black mixing rate increased. Fourth, it can be seen that Disney uses color as a visual method to more clearly express the psychology of the villain character using color association. In conclusion, the color selection of animation characters should be carefully considered as a tool to convey the character's personality, role, and emotion beyond simply using color, and the color selection of characters using color associations and symbols strengthens the narrative structure. It is hoped that this study will help analyze and select the character color of animation.

Black hairy tongue is a benign medical condition, which is characterized by elongated filiform lingual papillae, with a typical carpet-like appearance on the dorsum of the tongue. We describe the case of a 70-year-old Korean female with black hairy tongue, who complained of black hairy tongue accompanied by xerostomia. The patient was treated with Jibaekjihwang-tang-gagambang and electric acupuncture for 13 days. Black hairy tongue was evaluated by its visual appearance and by calculating hue-saturation-brightness (HSB) and red-green-blue (RGB) values of images of the tongue using a photo-edit program. Salivary flow rate (SFR) was evaluated to evaluate oral dryness. After 13 days of treatment, the black fur disappeared, and the brightness and RGB values of the black fur increased. In addition, the SFR increased. We conclude that Korean medicine could be the treatment choice for black hairy tongue.

Total eight different winter mushroom (Flammulina velutipes) strains were characterized by comparisons of fruiting body morphology, hardness and color after growing at different temperature. Although variations depending on the strains were observed, in general, both stipe length and pilus diameter were shorter while pilus thickness was bigger as growing temperatures were decreased. No significant differences in stipe thickness were observed. The ASI4065 and 4151 had the tallest stipe and the ASI4021 had the shortest stipe. The ASI4103 strain had the biggest pilus diameter. The ASI4153 had most thick pilus, while the ASI 4021 had least thick pilus. Also, the ASI4166 had the most thick stipe and the ASI4065 had the most thin stipe. The hardness of white mushrooms were increased by decreasing growth temperatures, while no relationships between the hardness of brown mushrooms. In most strains, stipe were much stronger than pilei and white mushrooms were harder than brown ones. The strain having most strong stipe was ASI4021. Both ASI 4021 and ASI4166 had the most strong pilus. The color of pilus has much lighter than that of stipe. White mushrooms had high brightness value ranging from 70-90, while brown mushrooms showed low brightness value from 30-70. Saturation value was higher in brown mushrooms. Based on our study, it was shown that environmental conditions had some effects on winter mushrooms, but genetic differences among strains were more important factors to determine most characteristics of winter mushrooms.

The purpose of this study is to understand the dyeing properties and color analysis of fabrics knitted with ramie, cotton, wool and acrylic by using scoria and to analyze whether the knitted fabrics can be used for industrialization by measuring color fastness after and before sliver-nano process. The following is the conclusions. Firstly, when ramie fabric regarding cotton, wool and acrylic was dyed at the temperature of $50^{\circ}C$ for fifteen minutes by using 10, 25, 50, 100g/ $\ell$ of scoria, dyeing absorption gradually increased up to 50g/ $\ell$, and over the point of 50g/ $\ell$ it showed slow increase. Secondly, regarding saturation, among ramie fabric, wool, cotton and acrylic, wool appears as the lowest brightness. Therefore, it can be dyed with bright color and the highest value. In terms of the value of chromaticity, wool also emerges as the lowest brightness. On the contrary, acrylic showed the lightest red as it had the value of the smallest b. Cotton takes the lightest yellow as the b value of the cotton showed the smallest. Thus, scoria dyestuff is a material that showed strong red and yellow on knitted fabric mixed with wool that is the biggest a. b value. Thirdly, in terms of dyeing fastness, sunlight fastness did not show noticeable differences before and after silver-nano processes, but in terms of washing and friction fastness, the material processed by silver-nano indicated that all knitted fabrics are over 4-5 point. which means silver-nano process can be effective for the industrial applications. As mentioned above, as a result of dyeing knitted fabrics with scoria, this study found a possibility of dyeing in the fabric materials, and if there is deeper dyeing experiments, fastness experiments and speculations, it might be possible to be a big issue just like loess and charcoal.

In this experiment, we used different addition ratio of the pigment and straw, to improve the decorative effect of the finishing touch while finding the kinds of clay colors taking on many sophisticated images, through the comparison between the various colors and textures of the surface. (1) To test the plaster material, added were the pigment of Red, Yellow, Black, and Green by the percentages of 0.5, 1, 1.5, 2, and 2.5, respectively, followed by the analysis of the color changes of the plaster material using the Photoshop (RGB). The results showed the bigger the addition ratio of the red color is, the higher the numeral values of RGB after it dried. However the brightness after drying didn't showed a big difference depending on the addition ratio. With the addition of the yellow pigment, the color difference between after and before drying was bigger in the order of Blue, Green and Red; the brightness increasingly rose while the saturation changed little. (2) When we scratched the plaster surface with U and V shape carving knives, the U knife didn't make a clean shape digging around the clay plaster material but with smooth textures, while the V knife made a clean cut, which represents its readily use in terms of the decorative function of the clay plaster. (3) In an experiment the surface texture was tested with different lengths and additions ratio of the straw, addition of 2cm straw by 1, 2, and 3% presented the most appropriate surface of the plaster.
