  • A color filter array (CFA) helps a single electrical image sensor to recognize color images. The Red-Green-Blue (RGB) Bayer CFA is commonly used, but the amount of the light which arrives at the photodiode is attenuated with this CFA. Red-White-Blue (RWB) CFA increases the amount of the light which arrives at photodiode by using White (W) pixels instead of Green (G) pixels. However, white pixels are saturated earlier than red and blue pixels. The pseudo multiple capture scheme and the corresponding RWB CFA were proposed to overcome the early saturation problem of W pixels. The prototype CMOS image sensor (CIS) was fabricated with $0.35-{\mu}m$ CMOS process. The proposed CIS solves the early saturation problem of W pixels and increases the dynamic range.

  • 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.

  • This paper investigates the color rank system of the Wonsam, ceremonial topcoat, worn as a court formal costume of the Joseon dynasty by analyzing the court costume system and the actual examples of wearing. The research shows that there were some discrepancies of the color rank of the Wonsam between the court costume system and the actual wearing examples. There were red, purple, blue, green, and black Wonsam in the Joseon dynasty. The color rank of the Wonsam is as follows: the Queen's color was red, the Crown Princess's was green and purple, the royal concubine's was usually green and blue, but they could wear purple when they won the King's favor. A prince's wife's was usually green, but she wore blue and purple if she became the mother of the King. The princess's was green, and the court lady's was green, blue, and black. In most cases, the textiles of Wonsam were made by silk with patterns, even though Joseon dynasty was ordered to use silks without patterns in court weddings and funeral ceremonies to avoid extravagance.

  • It is already known that the color of wool fabric dyed with disazo acid dyes could be changed in dyeing process and this is accelerated under alkaline condition. Focus was given to figuring out the mechanism of this color change, through the LC-MS analysis. In this study, no color change was seen in wool fabrics dyed with C. I. Acid Blue 113 under weak acidic, neutral and weak alkaline conditions for 1hour. However, the wool fabrics dyed under weak alkaline condition for a long time over 3 hours fumed reddish orange. When the wool fabrics dyed under weak acidic, neutral and weak alkaline conditions were treated with $0.5g/L\;Na_2C0_3$ solution, all of them turned reddish orange. On the other hand, the color of silk fabrics dyed with C. I. Acid Blue 113 were not changed after the same alkaline treatment. Wool contains cystine and cysteine, whereas silk does not. Due to the reversible reduction/oxidation process of cystine and cysteine in wool dyeing, the C. I. Acid Blue 113 of the dis-azo type is decomposed by reduction and consequently turned them into the reddish orange mono-azo types dye.

  • Efficient two-color-mixed white organic light-emitting diodes are presented herein by employing a sky-blue phosphorescent dopant of iridium(III)bis[4,6-(difluorophenyl)-pyridinato-N,$C^{2'}$]picolinate (FIrpic) and an orange phosphorescent dopant of bis(2-phenylquinoline)(acetylacetonate)iridium(III) ($Ir(phq)_2$acac) on the emissive layer. Very stable color variation under ${\Delta}$0.02 until a 5000 cd/$m^2$ brightness value was realized by efficient carrier control in a multi-stacked emitting layer of blue/red/blue colors. Maximum current and power efficiencies of 23.8 cd/A and 22.9 lm/W in the forward direction were obtained. With balanced emission from the two emitters, the white-light emission of high correlated color temperature of 7308K and the Commission Internationale de I'Eclairage coordinates of (0.30, 0.33) were achieved.
