  • Many Koreans have recently bleached their black hair to blond or a light color due to the influence of their favorite Korean idols. Bleaching effects were studied under various bleaching conditions, such as the concentration of oxidants, the ratio between bleach accelerant and oxidant, and treatment temperature and time. The degree of damage of bleached hair with the same color difference (${\Delta}E$) intervals was observed in SEM images, the retention of breaking load and the change of color after dyeing. The ratio between bleach accelerant and oxidant of 1:2.5 was an effective condition. $L^*$ values of the bleached hair treated with 9% oxidant increased to 90 min. At a treatment temperature of $30^{\circ}C$, $a^*$ values were maximum at 30 min and then decreased as time further increased; however, $b^*$ values of the bleached hair increased as the treatment time increased. At $45^{\circ}C$, both of $a^*$ and $b^*$ values showed a maximum at a specific time. Bleaching efficiency was influenced most by temperature, followed in order by time, and oxidant concentration. As the treatment time increased, $L^*$ values greatly increased with twice treatment; however, $a^*$ and $b^*$ values decreased. Bleached hair, which had a color difference of higher than 30, showed the scales were completely removed and the retention of the breaking load greatly decreased. Highly bleached hair showed a great decrease in $L^*$ values by dyeing; however, dyeing with bright colors was more indicative to the effect of bleaching.

  • Guanine nucleotide-binding protein subunit alpha-s ($Gn{\alpha}s$) is a small subunit of the G protein-couple signaling pathway, which is involved in the formation of coat color. The expression level and distribution of $Gn{\alpha}s$ were detected by quantitative real-time-polymerase chain reaction (qPCR), western blot, and immunohistochemistry to investigate the underlying mechanisms of coat color in white and black skin tissues of mice. qPCR and western blot results suggested that $Gn{\alpha}s$ was expressed at significantly higher levels in black mice compared with that of white mice, and transcripts and protein possessed the same expression in both colors. Immunohistochemistry demonstrated $Gn{\alpha}s$ staining in the root sheath and dermal papilla in hair follicle of mice skins. The results indicated that the $Gn{\alpha}s$ gene was expressed in both white and black skin tissues, and the expression level of $Gn{\alpha}s$ in the two types of color was different. Therefore, $Gn{\alpha}s$ may be involved in the coat color formation in mice.

  • In ancient times, hairstyle varies according to tribes. Because it is a social product that depends on status, class, and gender within the tribes, research on the hairstyle is an important source for studying the culture of the tribes. The purpose of this study is to analyze hairstyle of the Scythians and to understand the culture of the Scythians. Furthermore, the purpose is to identify the ethnic group based on this research. And it is intended to use the results as a comprehensive resource for research on the origins of Korean ancient costumes. As a research method, literature study and artifact analysis were performed concurrently. Data for artifact analysis were taken directly from the Eremitage Museum in St. Petersburg, Russia, where the researcher visited for this study. The conclusions of this study are as follows: Hairstyle of the Scythians were classified into three types: straight hair, braided hair, and tied hair depending on social status, age, and region. Straight hair was usually seen with kings, royalty, and warriors, and the hair length varied according to their status. Braid hair appears by a depiction of an old man and young Scythians. Tied hair was observed in the warrior. The beard was divided into chin-beard and mustache. Long chin-beards and mustaches were mostly observed in the ruling classes, while medium length chin-beards and short mustaches were considered the most common form of beard because they appeared in most classes. The young Scythians, regardless of their status, had no beard.

  • In the Edo period speaking of hair culture, common women wore decorative pigtail ribbons on the right, and twisted from side to side their tressed hair in such a manner as ungeunmeori and traemeori. Instead of gachae, common women used gogae made of their own hair, ungeunmeori on forehead, or jjokjinmeori at the back of head. During the Edo period, people women naturally exposed their necklines as a way of exposing their faces in the aesthetically ceremonial act of wearing make-up. As for lipsticks, they rouged extracts from red petals of safflowers mainly on their lips, and sometimes on their cheeks by blending this with white powder. Samurai families disliked women who wore thick lip makeup. In the latter period, women painted their necklines or foreheads black, applied a small amount of rouge on their cheeks thinly or thickly, and colored a reddish color into their fingernails by using petals and leaves of balsam flowers. Despite the chronological and spatial proximity of the King Jeongjo period and the Edo period, it was found that there were no similarities between two countries' cosmetic cultures. Moreover, it was discovered that current TV dramas were being produced, even not based on historical evidence in the Jeongjo period.

  • 본 연구는 재래형 유색계통계와 상업용 백색 산난계의 혈중 지질과 단백질 함양을 비교하기 위하여 재래형 유색계통계로서 황갈색계 10수, 녹흑색학 13수, 백색계 7수, 오골계 10수를, 개량형으로서 상업용 백색산난계(Nick chick) 30수를 선정하여 동일한 사료를 1개월 간 급이한 다음 혈청중 Cholesterol, triglyceride 및 protein 함양을 측정한 결과를 요약하면 다음과 같다. 1. 혈청 cholesterol 함양은 상업용 백색산난계 ($172.50\pm$13.45 mg/100 $m\ell$)에서 고도의 유의차(P<0.01)를 보였고 유색계통보다는 백색계통계에서 다소 높았고 유색계통간은 비슷했다. 2. 혈청 triglyceride 함양은 재래형 유색계간에는 차이가 없으나 상업용 산난계에서 유의성을 나타냈다. (p<0.01) 3. 혈청 protein 합양은 상업용 산란계에서 $6.24\pm$0.23 mg/100 $m\ell$으로서 재래형보다 유의하게 높게 나타났다. (p<0.01) 이상과 같이 재내형 유색계통보다 상업용 산난계에서 혈중 지질과 protein 농도가 높은 것은 닭의 개량정도에 의한 차이로서 상업용 산란계는 섭취한 사료의 영양소 흡수율이 높았기 때문인 것으로 사료된다.
