This study analyzed the coat color-related genes of MC1R, ASIP, ECA3-inversion, and STX17 of 1,462 Jeju horses administered by the Jeju Special Self-Governing Province. This was done to investigate the distributional characteristics of coat color-related genes in the Jeju horse group and the changes of its coat color-related genes by generation. The genotype frequency of the MC1R gene of $E^+/E^+$ and $E^+/E^e$ related to black coat color was 0.122 and 0.447, respectively, while $E^e/E^e$ of the chestnut genotype was 0.429. The genotype frequency of the ASIP gene of $A^A/A^A$, $A^A/A^a$, and $A^a/A^a$ was 0.46, 0.448, and 0.091, respectively, where the genotype frequency of $A^a/A^a$ turned out to be relatively low. The To/To and +/To genotype that manifests the Tobiano shape was 0.001 and 0.119, respectively, with the share of Tobiano shape around 12%. The genotype frequency of G/G and G/g of STX17 related to grey coat color was 0.002 and 0.680, respectively, with the share of grey horses among the Jeju horse group at 68.2%. As for the change of coat color genes by generation, no large changes were observed in the MC1R and ASIP genes. In ECA3-inversion, the To allele that manifests Tobiano significantly decreased following the generational change (p<0.05), while the STX17 G allele related to grey coat color significantly increased following the generational change (p<0.05). It will be necessary to examine the coat color genes when selecting breeding horses so that the diversity of coat colors among the Jeju horse group can be maintained.

Having silk dyed with some pigment extracted from the skin of an onion, examined the change of color by time and frequency of dyeing and a mordanted cloth, and the antibiosis of a dyed cloth and a mordanted cloth. The result of this were as follows ; 1. The pigment of an onion was easily extracted in the hot water of $40^{\circ}C$ and much more extracted as the temperature of water rises($70^{\circ}C$). 2. As a result of dyeing it by the change of time, 30minutes, 60minutes, 90minutes and the frequency of dyeing, once, twice, three times after filtering the extracted solution, the one dyed three times for 30minutes was the best. 3. The difference of color of a mordanted cloth was the highest in the mordant of $SnCl_2\;2H_2O$ on the basis of the value of L of the non-mordant dyed three times. 4. The mordant of copper sulfate was proved to have the highest antibiosis in the antibiosis of a dyed cloth and a mordanted cloth, and it was proved that the pigment of the skin of an onion had excellent antibiosis.

The purpose of this study is to investigate and analyze the actual conditions of consumer damage occuring in the use of clothing products. The data used for analysis included 470 cases, which were deliberated by requesting consumer disputes deliberation at the consumer consultation room of Masan YWCA at the Kyeongsangnamdo Consumer Life Center belonging to the Kyeongnam provincial office. The disputes regarding the clothing products insisted that consumers suffered damage for the period from March, 2011 to June, 2013. The data processing was carried out by SPSS 14 and the statistics techniques used went through a cross tabulation analysis and ${\chi}^2$-test. The results are as follows. The difference in the analysis result of purchase path and material as to kinds of clothing products showed a significant difference. The damage types of clothing products were classified into five types: change of color, change of style, change of surface and touch, breakage of subsidiary materials, and others. The damaged clothing products showed a difference for damage frequency according to the items of clothing products; in particular, damage frequency for change of color appeared high. The damage contents of change of color were identified as metachromatism, discoloration and yellowing, stain occurrence, and decolorization. The damage responsibility for these clothing products appeared to be various as to clothing items, but was higher at dry cleaners and manufacturers.

This study was carried out to investigate the association of POU1F1 (POU domain, class 1, transcription factor 1, Pit1, renamed as POU1F1) gene with backfat thickness (mm), carcass weight (kg), pH, and color values ($L^*$, $a^*$, $b^*$) in crossbred pigs (Landrace ${\times}$ Yorkshire ${\times}$ Duroc). Frequency of the AA genotype indel was at the highest level (66.67%). Frequency of A allele (0.81) was higher than that of b allele (0.19). This population followed Hardy-Weinberg equilibrium. Carcass weights and $a^*$ values of the three genotypes were all significantly different (p < 0.05), respectively. However, backfat thickness, $L^*$, $b^*$, visual color, and pH of the three genotypes were not significantly different (p > 0.05). Visual color was negatively correlated with $L^*$ (r = -0.521) and $b^*$ (r = -0.390) values, $L^*$ value was correlated with $b^*$ (r = 0.419) value, and $a^*$ value was positively correlated with $b^*$ (r = 0.612) value. These results indicate that the POU1F1 gene affected carcass weight and meat redness.

The rapid development of digital media and communication network urgently brings about the need of data certification technology to protect IPR (Intellectual property right). This paper proposed a new watermarking method for embedding contents owner's audio signal in order to protect color image IPR. Since this method evolves the existing static model and embeds audio signal of big data, it has the advantage of restoring signal transformed due to attacks. Three basic stages of watermarking include: 1) Encode analogue ID owner's audio signal using PCM and create new 3D audio watermark; 2) Interleave 3D audio watermark by linear bit expansion and 3) Transform Y signal of color image into wavelet and embed interleaved audio watermark in the low frequency band on the transform domain. The results demonstrated that the audio signal embedding in color image proposed in this paper enhanced robustness against lossy JPEG compression, standard image compression and image cropping and rotation which remove a part of image.

The purpose of this study were to investigate clothing design preference (style, color, fabric print, kinds of fabrics) & satisfaction with the fit of ready-to-wear clothing for older Men. For this study, the questionnaires were administered to 650 older men in seoul from June to August, 1998. Employing a sample of 504 data were analyzed by mean, frequency and percent. With respect to clothing design preference, they prefer suit the style of outdoor clothing on going-out. On distinguish clothing into formal wear & casual wear, the color preference due to seasons has difference in spring clothing. Regarding the degree of fabric pattern preference, nonpattern single color fabric has occupied in formal wear, pattern in casual wear. Regarding the degree of fabric preference, they take a serious view of shape preservation in formal wear, utility (washing, sweat absorption) in causal wear. Suit has the lowest satisfaction in the fit of ready-to-wear clothing. Sleeve length the lowest in the degree of satisfaction for each part.

In this paper, we propose a virtual sound localization algorithm which improves the sound localization accuracy and sound color preservation for two channel and multi-channel surround speaker layouts. In conventional CPP laws, the sound direction is different from the panning angle and the sound color is different from real sound source especially when the speakers are spread out widely. To overcome this drawback, we design a virtual sound localization algorithm using directional psychoacoustic criteria (DPC) and sound color compensator (SCC). The analysis results show that in the case of the proposed system, the sound direction is the same as the panning angle in the audible frequency range and the sound color is less deviated from a real sound source than the conventional CPP law. In addition, its performance is verified by means of subjective tests using a real sound source.
