This paper is a study on the expression of Clothing and Textiles recorded in $\ulcorner$Genjimonokatary (원씨물어)$\lrcorner$. This book is a novel written by a Japanese sextant worked in the Royal Court around the year 1010. In this book, about 110 different kinds of Garments, Ornaments, Colors and Materials were mentioned. The results of this paper were as follows. 1. About the Garments 8f Ornaments ; All the Clothing and Textiles in $\ulcorner$Genjimonkatary$\lrcorner$ were reflections of the reality of that time. In the Clothing, Color, Textile and even Hair style, the Symbol of Buddism appeared. Many technical methods were developed in the garment shaping, dyeng and wearing methods. 2. About the Colors Sf Dyes; There were many kinds of Color SE Dyes described in $\ulcorner$Genjimonokatary$\lrcorner$. This means color was developed more than other elements in that period. Among them, gray and black colors were mentioned, this means Buddist Color was fashioned in that period. $\ulcorner$Kasaneno-irome (강색목)$\lrcorner$ was changed from Ungan (운간) that had been origined of China and Korea. But it became one of the Japanese Costume. That have some reasons, for instance, high materials could not be imported from other countris and many people were controlled by the Taboo of clothing (금제) so they wanted the better method, such as Kasaneno-irome. Many kinds of colors'name was origined from flowers and plants. It also represented the seasons. Yurusi-iro (청색) was meaning the permitable color to the popular people. Without the head word, Deep Color' and 'Pale Color' meant those things of the purple and red. 3. About the Materials IE Patterns : The materials imported from other country, China and Korea, were good in quality, but those produced in Japan were not good. There were many kinds of dyeing method, especially Srijome (신염) was very special and nice method in that period.

The purpose of this study is to extract the color chip from the works of Matisse with the exotic tastes, to analyze the characters of adjacent colors, and to suggest the color coordination of artistic character. The research method is based on the literature study which analyzes visual materials. The results are as follows. Considering the colors of Japanese taste, He employs vivid and strong tone in red, yellow, and blue, light tone in pink, purple, and green and deep tone in green, purple, blue and black. His color scheme is very bold and splendid. In his Algerian taste, red is very popular, but an attention should be paid in his development of orange and blue tones. In general, the usage of various tones brings colors into less relief and make the contrast of tones more conspicuous. His Spanish taste, based on red and orange, attracts attentions with strong impressions, but sometimes, dark or adjacent pale tones creates strong, mild and murky atmosphere. The Moroccan taste, based on the development of blue tones which have strong attraction implies the lightness but represents silent and calm. The Rumanian taste, represented in primary colors of red, yellow and blue and achromatic colors is bright and clear. In addition, its light tone in various colors represents peace and romance. The coordination of the exotic colors with the unique adjacent colors created by Matisse is not based on the established color coordination theory, but extracts colors in the aspect of culture borrowing. Therefore, it can double the effects of the color scheme expressed in the existing designs and be used as the global and multi-cultural design sources.

With the rapid development of deep learning, Depth Map Super-Resolution (DMSR) method has achieved more advanced performances. However, when the upsampling rate is very large, it is difficult to capture the structural consistency between color features and depth features by these DMSR methods. Therefore, we propose a color-image guided DMSR method based on iterative depth feature enhancement. Considering the feature difference between high-quality color features and low-quality depth features, we propose to decompose the depth features into High-Frequency (HF) and Low-Frequency (LF) components. Due to structural homogeneity of depth HF components and HF color features, only HF color features are used to enhance the depth HF features without using the LF color features. Before the HF and LF depth feature decomposition, the LF component of the previous depth decomposition and the updated HF component are combined together. After decomposing and reorganizing recursively-updated features, we combine all the depth LF features with the final updated depth HF features to obtain the enhanced-depth features. Next, the enhanced-depth features are input into the multistage depth map fusion reconstruction block, in which the cross enhancement module is introduced into the reconstruction block to fully mine the spatial correlation of depth map by interleaving various features between different convolution groups. Experimental results can show that the two objective assessments of root mean square error and mean absolute deviation of the proposed method are superior to those of many latest DMSR methods.

본 논문은 수묵화와 채색화에서 색채 사용이 다름을 착안하여 수묵화,채색화 그림의 스타일 양식 차이에서 오는 결과를 작품위주로 보여주며 소개하고 있으며 다양한 동양회화를 색채 사용 형식에 따라 수묵담채, 중채, 진채, 현대채색화의 네 가지 군으로 정리 하였다. 수묵화는 재료적 특성으로 인해 생긴 그림양식에서 색채는 담하게 선을 넘지 않는 범위에서 올라가다보니 고유색을 지정해주는 역할 이상이 아닌 그림의 보조적인 역할에 머무르게 되었고 그럼에도 불구하고 진한 색채를 보이는 몇 작품이 있으며 이를 중채라 불렀고 진한 채색 그림들은 단순히 색채로만 많은 부분을 표현해야하기 때문에 채색화의 재료적 특성과 함께 색채가 아주 중요한 부분을 차지하게 되었다. 이와 같이 그림의 양식 스타일에 따른 색채 사용의 차이에 대해서 본 논문은 정리하고 있으며 또한 현대에 와서는 서양화 같은 채색 작품도 많으므로 현대 채색화의 다양성을 작품의 예로써 제시하였다. 이러한 다양성 속에 현재진행형 작품들이 계속 전통을 이으며 현대적인 미감으로 동양 색채를 잘 풀어가야 하며 본 논문은 전통 회화와 현대회화가 잘 조화된 작품을 하는데 도움이 되고자 채색화의 다양성을 연구, 분류하였다.

한국전통색이란 시대를 초월하여 한국민족의 삶속에 살아있는 색이다. 이러한 전통색 중 한국전통색을 대표하는 청·홍의 색조특성을 알아보기 위하여 조선시대의 색명과 염직유물의 색조를 조사하였다. 한국전통색 청·홍의 색조를 조사하기 위해여 먼저 조선시대의 문헌을 통하여 출현색명을 조사하였다. 색조를 나타내는 한국말에는 대단히 다양한 형용사가 앞에 붙어 색조를 특징짓는다. 색명에는 여러유형의 형용사들이 앞에 붙는데, 그 중에 대표적인 것은 농색과 담색을 나타내는 형용사들이다. 이처럼 제한된 색명의 가능성을 증가시키기 위하여 조선인들은 다양한 톤의 청색계(32색)와 홍색계(40개)의 색명을 만들어 내었다. 이러한 청·홍색계의 출현율은 대단히 높고, 조선시대의 궁중복식에서도 주조색으로서 사용되었다. 조선인은 다양한 청·홍색계의 배색으로 그들의 음양론에 기초한 색체관과 세련된 미의식을 표현하였다. 박물관에 있는 염직유물들의 색체는 측색되어 먼셀컬러시스템과 ISCC-NBS의 계통색명법에 의해 분류되고, 고찰되었다. 또한 전통색조인 남염과 홍화염이 산업체에서 이용되어지도록, 남염과 홍화염의 염색방법을 계량화하여, 데이터를 제시하였다.

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.

A recent study to determine the fall is focused on analyzing fall motions using a recurrent neural network (RNN), and uses a deep learning approach to get good results for detecting human poses in 2D from a mono color image. In this paper, we investigated the improved detection method to estimate the position of the head and shoulder key points and the acceleration of position change using the skeletal key points information extracted using PoseNet from the image obtained from the 2D RGB low-cost camera, and to increase the accuracy of the fall judgment. In particular, we propose a fall detection method based on the characteristics of post-fall posture in the fall motion analysis method and on the velocity of human body skeleton key points change as well as the ratio change of body bounding box's width and height. The public data set was used to extract human skeletal features and to train deep learning, GRU, and as a result of an experiment to find a feature extraction method that can achieve high classification accuracy, the proposed method showed a 99.8% success rate in detecting falls more effectively than the conventional primitive skeletal data use method.

This investigation presented conventional triaxial and creep-permeability tests on sandstones considering thermally-induced damage (TID). The TID had no visible effects on rock surface color, effective porosity and permeability below $300^{\circ}C$ TID level. The permeability enlarged approximately two orders of magnitude as TID increased to $1000^{\circ}C$ level. TID of $700^{\circ}C$ level was a threshold where the influence of TID on the normalized mass and volume of the specimen can be divided into two linear phases. Moreover, no prominent variations in the deformation moduli and peak strength and strain appeared as TID< $500^{\circ}C$ level. It is interesting that the peak strength increased by 24.3% at $700^{\circ}C$ level but decreased by 11.5% at $1000^{\circ}C$ level. The time-related deformation and steady-state creep rate had positive correlations with creep loading and the TID level, whereas the instantaneous modulus showed the opposite. The strain rates under creep failure stresses raised 1-4 orders of magnitude than those at low-stress levels. The permeability was not only dependent on the TID level but also dependent on creep deformation. The TID resulted in large deformation and complexity of failure pattern for the sandstone.
