In recent years, the digital media environment has begun to diversify, with a greater focus being placed on user-centric design. With the development of digital technology, the digital media environment has formed a vast network of information, which supports interactive communication between people, creating a need for user-centric research. Mobile displays, as a representation of the digital media environment, have the advantage of mobility through the use of thin screen displays and low-performance image sensors, which allow for miniaturization and power saving. However, this results in reduced colour accuracy compared to large displays. This study investigates users' colour perception when using dark and light mode mobile displays. Colour perception was measured using a psycho-physical experiment, which controls each colour attribute based on the 12 colours of KS. The results were analysed to determine whether there is a difference in colour perception between dark mode and light mode, and if the difference was statistically significant. Future research directions based on the results are then discussed.

The CMS(color management system) software was to enable consistent color reproduction from original to reproduction. The CMS was to create RGB monitor and printer characterization profiles and then use the profiles for device independent color transformation. The implemented CMM(color management module) used the CIELAB color space for the profile connection. Various monitor characterization model was evaluated for proper color transformation. To construct output device profile, SLI(sequential linear interpolation) method was used for the color conversion from CMYK device color to device independent CIELAB color space and tetrahedral interpolation method was used for backward transformation. UCR(under color removal) based black generation algorithm was used to construct CIELAB to CMYK LUT(lookup table). When transforming the CIE Lab colour space to CMYK, it was possible to involve the gray revision method regularized in the brightness into colour transformation process and optimize the colour transformation by black generation method based on UCR technique. For soft copy colour proofing, evaluating several monitor specialism methods showed that LUT algorithm was useful. And it was possible to simplify colour gamut mapping by constructing both the look-up table and the colour gamut mapping algorithm to a reference table.

The philological consideration of Korean Buddhist Monk's robe and its reviving have been investigated in traditional way. The configuration and colour of Korean Buddhist monk's robes have been properly adapted for an period, territory, and atmospheric phenomena. In case of Korea, introduced Buddhism from China realize modern robe from under the influence of fusion of Chinese ornament culture and Korean traditional ornament culture. As a result of this modern robe has been consisted of a Buddhist monk's robe and a cope. The modem robes has been significantly affected by industrialization, contrary to ancient time taxed robes as public imposts. At present be familiar in mass production we have a preference for the easier way in making and even color forming. In this paper it is focused on dyeing part, which recognized its important in latest time, at first declined according to appearance of chemical dye, evaluated its convenience in use. That is, it is increased natural dye, people begin with recognition of difference of physical properties for dress dyed with chemical pigment and that with natural pigment. In consequence, I have presented that both making colour of gray using traditional method, and three demolished-color prescribed by Buddhist law. Of course, though it become generally know that dyeing of robes occupied significant part of traditional natural dyeing. But in case of religion, it also is important to know symbolical meaning involved in its colour. Most of Buddhism-believers or even Buddhists who actually be dress in robe are without knowing the meaning of colour, or its revealing method. There, I have considered mating three colour of demolished- color included blue, black, and red, and also represented dyeing method of Buddhist monk's robe using both charcoal and ink-spick. From religious font of view, as robes contains involving of blessing, I have an intention of improvement way in dyeing and succession and development of traditional culture through consideration of traditional dyeing method. And I have also intended to restoration the value of robe's colour, disappeared by the time. moreover, I have shown that dyeing with natural pigment is profitable for both environment and sanitary aspect.

Objective: This study was conducted to estimate effect of single nucleotide polymorphisms (SNP) on the estimated breeding value of Hungarian Grey (HG) bulls and to find markers associated with horn colour. Methods: Genotypes 136 HG animals were determined on Geneseek high-density Bovine SNP 150K BeadChip. A multi-locus mixed-model was applied for statistical analyses. Results: Six SNPs were identified to be associated (-log10P>10) with green and white horn. These loci are located on chromosome 1, 3, 9, 18, and 25. Seven loci (on chromosome 1, 3, 6, 9, 10, 28) showed considerable association (-log10P>10) with the estimated breeding value. Conclusion: Analysis provides markers for further research of horn colour and supplies markers to achieve more effective selection work regarding estimated breeding value of HG.

In order to the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the inspection of face colour and tongue & the auscultation and olfaction. The inspection on the individual characteristic factor was analyzed the face colour, inspection of tongue. The auscultation and olfaction on the individual characteristic factor was analyzed the 25 types by the five-voice (五音) in Huang Di Nei Jing (黃帝內經). As the results, the individual characteristic factor is very important item of the four methods of diagnosis and the differentiation of syndromes. And Therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

Kublai Khan on a Hunting Trip were painted by Liu Guan-dao. This painting gives us very important information for understanding cosume of Yuan dynasty because of realistic description. We studied the name of costume of the king Shizu in this painting by using the way of comparison his costume with another paintings, the records and archaeological finds. This study showed that the costume of the king Shizu is judged to be Jisun, the traditional costume of Mongolian own meaning one colour. The name of each is the Yinshu warm hat, being making into the for of a kind of rodents, the Yinshu Jisun, the Red colour Jisun, being railed on the robe, and the Cloud boots cover. And we found that the decoration on the neck and sleeve tib of the Yinshu Jisun had been made by sable furs, and the decoration on the surface had been made by tails of them, going by the name of Rondes at that time. It also showed that the meaning of one colour of the Jisun is not only just appearing one colour on the one person but also being able to appear two set of one colour.

Many monoterpen-erivatives are contained in edible plants. Some monoterpen-derivatives have been assessed as negative factors in the food safety. Among them thuone and 4-caranone are important toxic constituents of many plant essential oils. In this study, convenient detection methods of thujone and 4-caranone in oil were developed. The colour reactions of toxic thujone and 4-caranone were performed in oder to detect those in foods and oils. Sodium pentacyanonitrosylferrate (II) react with thujone to produce thujzoximinocarboxylic acid which becomes the six ligand in the ferrate complex (red colour reaction for thujone). Sodium pentacyanonitrosylferrate (II) cleaves 4-caranone to the red ferrate complex of caranketonic acid.

Objective: Qingyu pig, a Chinese indigenous pig breed, exhibits two types of coat colour phenotypes, including pure black and white with black spotting respectively. Melanocortin receptor 1 (MC1R) and agouti signaling protein (ASIP) are two widely reported pivotal genes that significantly affect the regulation of coat colour. The objectives of this study were to investigate whether the polymorphisms of these two genes are associated with coat colour and analyze the molecular mechanism of the coat colour separation in Qingyu pig. Methods: We studied the phenotype segregation and used polymerase chain reaction amplification and Sanger sequencing to investigate the polymorphism of MC1R and ASIP in 121 Qingyu pigs, consisting of 115 black and 6 white with black spotted pigs. Results: Coat colour of Qingyu pig is associated with the polymorphisms of MC1R but not ASIP. We only found 2 haplotypes, $E^{QY}$ and $E^{qy}$, based on the 13 observed mutations from MC1R gene. Among which, $E^{qy}$ presented a recessive inheritance mode in black spotted Qingyu pigs. Further analysis revealed a g.462-463CC insertion that caused a frameshift mutation and a premature stop codon, thus changed the first transmembrane domain completely and lost the remaining six transmembrane domains. Altogether, our results strongly support that the variety of Qingyu pig's coat colour is related to MC1R. Conclusion: Our findings indicated that black coat colour in Qingyu pig was dominant to white with black spotted phenotype and MC1R gene polymorphism was associated with coat colour separation in Qingyu pig.

The lightness, chroma and hue tolerances with respect to the standard colour position in the CIELAB space have been studied in detail using the various existing data sets and the set form this study. The lightness tolerance showed a clear dependency upon the metric lightness for medium to light colour, but in the case of dark colours there was a discrepancy between the data sets. Both the chroma and hue tolerances showed dependency upon both the chroma and hue-angle and not the single dependency upon the metric chroma, as assumed in the CIE94 formula. New weighting functions were derived from the above experimental evidence, and finally a new formula, LCD(Leeds Colour Difference) was proposed. The LCD formula is nearly as simple and flexible as CIE94 but smoothes the individual weighting functions, especially for lightness tolerances for light colours and chromaticity discrimination near the blue region.
