As an important visual element, color in animated films can not only depicts the reality, but also conveys emotion and meanings, which play an important role in shaping the space of animated films. As one of the most outstanding animated films, Coco uses bold and unique color language to shape the film space. It uses the national color to blend the Mexican culture into the story space making it full of Mexican regional and cultural connotation, uses color contrast to shape the physical space, highlighting the three-dimensional and deep sense of the physical space. And also uses color association to create the psychological space, leading audience into the spiritual world of the film. Based on the analysis of the Coco, we an see that when shape the film space of animation, the film maker should give full play to the characteristics and function of color, and apply different color language to shape different space according to the role of the film space, so as to expand and deepen the connotation and expressiveness of film space.

In order to reveal the vertical variation of physical properties in deep-sea sediments, deep-sea sediment cores were collected at 78 stations using a multiple corer in the KR5 area, one of the Korea contract areas for manganese nodule exploration, located in the northeast equatorial Pacific. Based on the color of sediments, sampled sediment cores were characterized into three lithologic units (unit 1,2, and 3). In all sediment cores, three units appear systematically; unit 1 lies at the top of cores and unit 2 and/or unit 3 appear to underlie unit 1 or alternate with unit 3. Unit 1 layer from the top of cores shows dark grayish brown to dark brown with mean thickness of 10.2cm. Unit 2 and 3 layers show very dark brown to black color and yellowish brown to brown color, respectively. According to the physical properties of the deep-sea sediment cores, sediment column can be divided into three sections. Section A $(0{\sim}15cm)$ in subbottom depth consists mostly of unit 1. Mean values of physical properties of section B $(15{\sim}30cm)$ in subbottom depth are similar to those of section C (>30 cm) in subbottom depth. However, the physical properties of section B were more variable than those of section C because of the high activity of bioturbation in section B. These results will provide valuable information for selecting suitable sites for mining manganese nodules in the Korea contract areas.

Objective: The aim of this study was to investigate the association between conceptual metaphors of affect and physical dimensions. Background: The evidence that affect is unconsciously linked to physical dimensions(e.g., position and color) has been obtained in western cultures. However, in eastern cultures, especially, in Korea, it has been seldom tested. It is indispensable to examine whether or not cultural differences exist for better understanding of the conceptual metaphors. Method: 50 positive and 50 negative words were adopted from previous studies in order to determine the relationship between physical domains and abstract affect. Three hypotheses were tested in this study: (1) Good is up. (2) Good is bright. (3) Good is right(for right-handers). The automatic association between valence(positive vs. negative) and vertical position (up vs. down) was investigated in experiment 1, in which 100 words were randomly presented on either the top or the bottom of a LCD screen and the evaluation time of the presented word was recorded. The unconscious association between valence and color(white and black) was examined in experiment 2, where each word was randomly presented in either white or black. Lastly, we tested whether right-handers tend to associate rightward space with positive ideas and leftward space with negative ideas. Results: Reaction time was faster when words were presented in metaphor congruent domains(e.g., 'positive words on the top, in bright color, and on right space vs. negative words on the bottom, in dark color, and on left region) than when they were shown in metaphor incongruent domains. Conclusion: The results might give the groundwork for various directions in further understanding perception, emotion, and behavior. Application: This study may provide useful points to GUI designers and service developers if further studies enhanced in validity and reliability are followed.

The purpose of this study is to empirically identify the effect of women's motivation for choosing makeup colors on their perception of physical attractiveness and self-respect. Participants in this study were surveyed through questionnaires for 256 employees in Seoul and Gyeonggi-do, and the collected data were analyzed in depth using statistical analysis methods of frequency analysis, factor analysis, and multiple regression analysis. The results derived through a series of research procedures are as follows: First, the motivation for women in the workplace to choose makeup colors showed a statistically significant influence on physical attraction perception. Second, the motivation for women in the workplace to choose makeup colors showed a statistically significant influence on self-esteem. Third, office workers' perceptions of physical attraction had a statistically significant impact on self-esteem.

In the current era of rapid digitization of the fashion industry, this study aims to facilitate the digitization of local Hawaiian fashion products. The research compares and analyzes the patterns and colors of digital clothing products sold on Zepeto, a metaverse platform, and those of physical products sold both, online and offline, by six specialized brands with stores in Honolulu, Hawaii, or Hawaiian signature clothing products. The following results were obtained: First, physical products generally display various patterns, such as animals, plants, geography, regions, and beaches. However, the pattern diversity of digital products is relatively limited, with a tendency to focus on plant and animal designs, which are Hawaii's signature patterns. Second, the color analysis results demonstrate that chromatic color groups, such as blue and red, were the most popular in physical products, whereas digital products used mostly green and neutral colors. Considering that physical products are sold both, online and offline, this is presumed to be due to differences in expression techniques and customer responses to digital and physical products, rather than market differences. To facilitate the digitization of Hawaiian local fashion products, a library that accommodates physical products in a variety of patterns and colors must be secured, and continuous modifications must be made to match the overall fashion trends.

Filter colorimeters have a set of spectral bands for which spectral responsivity is the same as the color matching function defined by CIE (Commission Internationale de I'Eclairage). We have designed a set of color matching function filters denoted by $\bar{x}-filter,\;\bar{y}-filter,\;and\;\bar{z}-filter$. Because the $\bar{x}-function$ has two transmission bands, two $\bar{x}-filters$ are designed to cover the $\bar{x}-function$. To design the filters, we developed a nonlinear least square fit program which determines the thickness of the color glasses by minimizing its spectral mismatch value ($f{_1}'$) to below 3 %. The design has been validated by fabrication of the $\bar{y}-bar$ filter, of which $f{_1}'$ was measured to be 2.8 %. Considering a LCD flat panel display as a device under test, we have calculated the systematic error of the colorimetric measurement using the designed filters.

A theoretical description and experimental demonstration of homodyne-detected two-color transient grating (2-C TG) signal are presented. By treating the coupled bath degrees of freedom as a collection of harmonic oscillators and using a short-time expansion method, approximated nonlinear response functions were obtained. An analytic expression for the two-color transient grating signal was obtained by carrying out relevant Gaussian integrals. The initial rising and decaying parts of the 2-C TG signal is shown to be critically dependent on the ultrafast inertial component of the solvation correlation function. The experimental results confirm the predictions of the theoretical model.

The sensibilities of cotton fabrics were subjectively evaluated by 126 subjects with 7-points scale questionnaires using the 4-dimensions and 8-axes system, which was composed of adjectives such as ‘masculine-feminine’,‘new-old’,‘casual-classical’, and ‘ambiguous-arranged’. And the sensibilities of cotton fabrics were classified through the cluster analysis. Also, we measured color and physical characteristics, which were variables to have an effect on the sensibilities of cotton fabrics. The sensibilities of cotton fabrics were classified into 8 groups such as ‘feminine, arranged, and classical sensibility’,‘arranged, classical, and old sensibility’,‘feminine sensibility’,‘new, feminine, and ambiguous sensibility’,‘casual and new sensibility’, and ‘ambiguous and old sensibility’The sensibilities of cotton fabrics were more influenced by color characteristics such as value, chroma, and hue than by physical characteristics.
