Yellow, one of the five direction colors, is a prevailing color in artificial dyeing. The color has implied and symbolized wealth and power since ancient times. Yellow has been extracted mainly from flowers. Shapes, colors and scents of flowers not only have enriched emotional mentality, but have also been used for medicinal herbs, and dyestuff since the very old days. Coloring matter from flowers is very beautiful, and it has been used for dyeing textiles. Textile dyeing have formed a color culture and developed a dyeing culture since ancient times. Flowers include a variety of color matters, and can be easily obtained around us. Therefore, flowers have been a widespread natural dyestuff. It is well known that beautiful colors can be extracted from flowers, which are eco-friendly and non-polluting. In addition, flowers are easily provided. In this study, yellow wild flowers were selected as subjects. Seven flowers with color matters distiguishable through the naked eye were used: Korean forsythia, golden-wave, Mongolian dandelion, sunflower, conflower, chelidonium and chrysanthemum. Coloring matters were extracted from the seven flowers, which have been used to create a variety of colors through various dyestuffs; and the colors have been analyzed and presented. Dyeing and coloring matters were tested and analyzed, and several types of dyestuff had also been scientifically measured after treatment.
Yellow poplar is well known commercial hardwood species in the world because of its availability, rapid growth, large size, excellent form, early natural pruning, and the good working quality of the wood. Therefore, yellow poplar (Liriodendron tulipifera L.) has been adopted in South Korea for decades ago, and its cultivating the saplings and silvicultural system have been studied. However, yellow poplar is still embroiled in controversy for utilization of use and worth. This species has not only advantages such as lower weight, light color, and higher machinability and bending processing, but also has disadvantages which are bad smell and different colors on heartwood and sapwood. In this study, the objective was that use of yellow poplar board as furniture materials by drying and painting process. Thirty years old yellow poplar was cut and dried for 7 days by high-frequency dryness. Adjustment of color tone to walnut color was conducted with multiple colorants and various number of spread times. Uniform color of yellow poplar on heartwood and sapwood was accomplished by applying 1 time stain (green), 2 times transparent primer, 1 time middle-painting (walnut), and 2 times top-painting (walnut) in sequentially. The painted yellow poplar board was used to manufacture table and dressing table. During the furniture manufacture process, no critical issues were occurred on part of jointing and painting. This painting method may be useful data for future use of yellow poplar as furniture materials.

Senescent effects are the gradual deterioration of function caused by biological aging. Senescent effects on color vision are not clearly understood even after considerable researches. Part of the reason is that the color vision is a complex phenomenon resulting from various factors such as organic systems, and the physical (neuro-optical) and the psychological (experiential) processes of color perception. We performed a field experiment on color perceptional differences due to aging vision. Our experiment was applied to two different groups in South Korea: an experimental group (46 subjects of over the age of 61 years) and a control group (49 subjects in their twenties). The experimental tools are comprised of (1) six gradual yellowing detector board (40%, 50%, 60%, 70%, 80%, 90%); (2) pairs of vivid-strong, vivid-deep, grayish-deep, deep-dull, and bright-light tones of Blue (B) and Purple (P) colors; (3) Red (R), Yellow (Y), Green (G), Blue (B), and Purple (P) colors of dull-tones and pale-tones; and (4) a questionnaire on the semantic differential scales of the color images and color differences. A diagnosis system of gradual yellow vision, developed by the authors for this study, was adapted to generate the color detecting boards. The results are as follows. (1) There are significant differences between the two groups in detecting colors that simulate 40% and 50% of yellow vision. (2) As to the color difference detecting ability between similar tones, the experimental group shows difficulties in pairs of vivid-strong tones and deep-dull tones of the B color. And (3), the emotional responses to the dull tone and the pale tone are not stable in the red, the yellow, blue, and purple. Thus, we empirically demonstrate the specific differences in color perception between the old and young groups.
The objective of this research was to evaluate the effects of dietary supplementation of blood meal (BM) as a source of histidine, and magnesium oxide (MgO) as a catalyst of carnosine synthetase, on carnosine (L-Car) content in the chicken breast muscle (CBM), laying performance, and egg quality of spent old hens. Four hundred eighty laying hens (Hy-Line$^{(R)}$ Brown), 95wk old, were allotted randomly into five replicates of six dietary treatments: T1; 100% basal diet, T2; 100% basal diet+MgO, T3; 97.5% basal diet+2.5% BM, T4; 97.5% basal diet+2.5% BM+MgO, T5; 95% basal diet+5% BM, T6; 95% basal diet+5% BM+MgO. Magnesium oxide was added at 0.3% of diets. The layers were fed experimental diets for 5wk. There were no significant differences in the weekly L-Car content in CBM among all treatments during the total experimental period, but some of the contrast comparisions showed higher L-Car in CBM of T6. The L-Car contents linearly decreased (p<0.01 or p<0.05) as the layers got older except in T4 (p>0.05). There were significant differences in egg weight (p<0.01) and soft and broken egg ratio (p<0.05). The control (T1) was highest in egg weight and T6 was lowest in soft and broken egg ratio. Among the parameters of egg quality, there were significant differences in eggshell strength (p<0.01) and egg yolk color (p<0.05). Magnesium oxide supplementation increased the eggshell strength and BM tended to decrease egg yolk color. Eggshell color, eggshell thickness, and Haugh unit were not influenced by BM and MgO. In conclusion, BM and MgO did not significantly influence the L-Car in CBM of spent layers. The L-Car content rapidly decreased as the layers became senescent. Eggshell strength was increased by MgO supplementation.

Objective: Eggshell color is an important indicator of egg quality for consumers, especially for brown eggs. Various factors related to laying hens and their environment affect brown eggshell coloration. However, there have been no studies investigating hepatic functions of laying hens with variable intensity of brown eggshell color. Therefore, this study was aimed to identify potential factors affecting brown eggshell coloration in aged laying hens at the hepatic transcriptomic level. Methods: Five hundred 92-wk-old Hy-line Brown laying hens were screened to select laying hens with different intensity of brown eggshell color based on eggshell color fans. Based on eggshell color scores, hens with dark brown eggshells (DBE; eggshell color fan score = 14.8) and hens with light brown eggshells (LBE; eggshell color fan score = 9.7) were finally selected for the liver sampling. We performed RNA-seq analysis using the liver samples through the paired-end sequencing libraries. Differentially expressed genes (DEGs) profiling was carried out to identify their biological meaning by bioinformatics. Results: A total of 290 DEGs were identified with 196 being up-regulated and 94 being down-regulated in DBE groups as compared to LBE groups. The Kyoto encyclopedia of genes and genomes (KEGG) analysis revealed that these DEGs belong to several biological pathways including herpes simplex infection (toll-like receptor 3 [TLR3], cyclin-dependent kinase 1, etc.) and influenza A (TLR3, radical S-adenosyl methionine domain containing 2, myxovirus [influenza virus] resistance 1, etc.). Genes related to stress response (ceremide kinase like) and nutrient metabolism (phosphoenolpyruvate carboxy-kinase 1, methylmalonic aciduria [cobalamin deficiency] cblB type, glycine receptor alpha 2, solute carrier family 7 member 11, etc.) were also identified to be differentially expressed. Conclusion: The current results provide new insights regarding hepatic molecular functions related to different intensity of brown eggshell color in aged laying hens. These insights will contribute to future studies aiming to optimize brown eggshell coloration in aged laying hens.
This study is to help make-up and coordination for image-making after analysis of facial color and shape of elderly women. The data was analyzed 55-75 years old 212 elderly women's face color and pictures by means of SPSS 12.0 statistics package. On the basis of the colorimetric data on face by Minolta CM2500D, this research considered the analysis of facial color, patternization of facial color and its analysis by age group; for the analysis of facial shape, this research patternized facial shape and analyzed its characteristic using both contour-based facial shape analysis and Kamata facial shape analysis. As for facial color, it was found that the lower age bracket has bright and reddish face, looking fine, while the higher age bracket has a conspicuously yellowish face, looking bad. The community of facial color is classified as 3 types and it was found out that the facial color of the subjects belonging to Type 3, whose L value is the largest, looked the brightest; the face of the subjects belonging to Type 2, whose a value is the largest, was much tinged with red, and the face of the subjects belonging to Type 1, whose b value is the largest were tinged with yellow. According to the analysis of facial shape, there appeared oval & long forms in the classification by contour, while there appeared a lot of downward-directed power and inner-directed power in the classification by Kamata, which is believed to reflect the phenomenon that their chin line becomes roundish and the facial length also tend to be longer due to aging.
An experiment was conducted to evaluate the effect of different levels of extracted pigment from Dietzia natronolimnaea biomass as a source of canthaxanthin in comparison with synthetic canthaxanthin on egg yolk pigmentation. The experiment used a completely randomized design (CRD). A total of 63 laying hens, 68 weeks old, were used and the birds were allotted to 7 dietary treatments with each treatment replicated three times with three hens per replicate. Treatments consisted of 3 levels of synthetic canthaxanthin (4, 8 and 16 ppm), 3 levels of extracted pigment from D. natronolimnaea biomass (4, 8 and 16 ppm) and control. Changes in yolk color were determined in 2 eggs taken at random, during the four week experimental period from each replicate. Supplementation of extracted pigment from D. natronolimnaea biomass had a significant effect on the color of egg yolks (p<0.05). Yolk color score of the control group was 6.83 in BASF color fan and the yolk color score of different extracted pigment levels was 11.00, 12.50 and 14.50, respectively. The yolk colors of different levels of synthetic canthaxanthin were 12.00, 14.00 and 15.00, respectively. The effect of pigment supplementation on egg yolk color was better explained by polynomial response curves. The $R_{2}$ indicated that for 3 supplementation levels of each pigment studied, over 90% of the color variation could be explained by the pigment concentration. The egg yolk color after 15 and 30 days of storage was not significantly different, but boiling reduced egg yolk color significantly (p<0.05).
The purpose of this study is to analyze the satisfaction, practical use, preference in design and recognition of the Saenghwalhanbok in the adult females living in Gyeongnam province. The data used for this study were collected by questionnaires and 420 questionnaires were used for statistic analysis. The data were analyzed by using the SPSS 8.0 to perform the ANOVA, $X^2$-test, t-test. The results of this study can be summarized as follows; Most women have Saenghwalhanbok for wearing in festive days. who showed good impression on the Saenghwalhanbok is high-educated people, and high-incommer showed positive preference as well. The color of blouse and skirt is different each other. The most preference color is soft color. The purchasing behavior on the Saenghwalhanbok was verified that there are planning of purchase because of convienience in wearing. The primary reason for not buying Saenghwalhanbok is price. So the goods of various level of price should be prepared, and the preference factors of purchasing for younger ages were color, patterns and design, and for old ages were quality of clothes, colors and patterns. Major application of the Saenghwalhanbok was found that wearing for festive days as it is Korean traditional costume.
Purpose: Facial tumor excision is a common cause of lower eyelid defect in old patients. Many methods have been introduced for the reconstruction of lower eyelid. However, conventional surgical method can cause various complications like scar, ectropion and unnatural color matching. Thus, we introduce a simple and aesthetically acceptable method for the reconstruction of lower eyelid defect. Methods: Three elderly patients with skin cancer in the unilateral lower eyelid were operated by the new method. Following a wide excision of skin cancer, subcilliary incision of lower blepharoplasty was carried out. Elevated skin flap of lower eyelid was redrapped for the correction of defect and the remnant skin from lateral portion of lower eyelid was used for full thickness skin graft (FTSG) to correct the remaining defect. Results: All grafts survived and color match of the graft was excellent without ectropion. Furthermore, wrinkles of the lower eyelid were improved after the blepharoplasty. Conclusion: Lower eyelid defect resulting from wide excision of malignant tumor in old patients could be reconstructed successfully by modifying the conventional lower eyelid blepharoplasty along with FTSG using the remnant skin.
The purpose of this study was to investigate the effect of children's personality traits and parental child-rearing attitudes on clothing attitudes and color evaluation of preschool children. The subjects for this study consisted of 360 five-year-old children who were attending a preschool and their parents in Cheju Island Korea. Employed mothers had significantly higher score on love acceptance attitude than unemployed mothers did. Female children had more conservative attitude on clothing sex-role than male children did There were no significant gender differences in parental child-rearing attitudes. There were significant relationships between gender and preferred clothing colors. Male children were more likely to prefer blue red, green, and prussian blue for the colors of clothing than were female children while female children liked pink yellow and orange more than male children. Boys selected blue and girls selected pink as the most preferred clothing color. Overall preschool children chose red as the most preferred color black as the most disliked color. The children's sex identification by clothing color was highly consistent with the conservative attitude of adults for all colors. That is preschool children identified pink red and yellow with female color while prussian blue blue and green with male color. Clothing interest of boys was influenced by the mother's state of employment and academic trait. The boys high in academic trait and whose mothers did not have job were high in clothing interest. Clothing management of boys was influenced by emotionality and love acceptance rearing Ttitude. Clothing independednce of boys was influenced by authority control rearing attitude Clothing sex-role of boys was influenced by familism trait. The boys high in familism trait had open-hearted attitude in clothing sex-role. Clothing interest of girls was influenced by academic trait clothing management by sociality clothing independence by emotionality and clothing satisfaction by familism trait. Therefore the more positive personality children had the higher clothing interest and the more desirable clothing attitudes they had.
