본 논문은 머리카락을 포함한 얼굴 영역 추출에 관한 것으로서, 보다 구체적으로는 조명변화에도 강인 한 얼굴영역 추출방법과 다양한 머리카락의 모양과 색의 변화에도 신뢰성 있는 머리카락 추출 방법에 관한 것이다. 일반적으로 얼굴영상은 개인의 특징을 잘 표현할 수 있는 정보로써, 영상에서 얼굴 영역을 추출하여 이를 실제 얼굴영상정보를 이용한 얼굴인식, 관상정보 서비스를 위한 전처리, 기반기술을 제공하고, 실사 캐릭터 제작에도 바로 적용될 수 있다. 기존의 템플리트 매칭, 곡선추적 알고리즘 등과의 같은 추출방법에서는 얼굴크기 변화, 안경 및 장신구의 착용 여부 그리고 조명의 변화에 따라 얼굴영역 추출하는 처리속도가 많이 걸리고, 성능이 크게 저하되는 문제점이 있다. 상기한 바와 같이 종래의 문제점을 개선하기 위하여, 본 논문에서는 얼굴의 크기변화, 안경 및 장신구의 착용 여부 그리고 조명의 변화에서도 얼굴 영역을 잘 추출 할 있는 방법과 다양한 머리카락의 색, 형태 변화에도 신뢰성 있는 머리카락 추출방법을 제안하였다.

Everyone's favorite color that exists naturally or artificially. This paper proposes that ow to find a suitable color for man. First of all, we find out about the base tone forming the color such as skin color, hair color, eye color. Next, we explained color theory of four seasons that color was divided according to skin color, hair color, eye color was diveded by spring, summer, autumn and winter seasons, and according to liking or nature. And look at the characteristics of each season's color.

This dissertation has been intented to grasp the components of personal colors and classify personal colors. The Method of the study was quasi-experimental. In the experiment to evaluate personal colors, the subjects was 315 male and female college students in Taegu and Kyungbuk area. The evaluations were analyzed by SAS and the methods used were descriptive statistics, cluster analysis, T-test. The results obtained were as follows: First, the major components of subjects personal colors were found to be the colors of skin and hair. Secondly personal colors were classified into three types: warm, cool, and ambiguous. Third types of personal colors tended to be different between men and women.

In forensic genetics, when it is not possible to confirm an individual's identity through STR profile analysis, additional information about the individual can be obtained using DNA-based phenotypic traits estimation. Recently, various researches have been conducted on methods to determine externally visible characteristics (EVC) such as eyes, hair, and skin color. However, relying solely on such phenotypic traits information has limitations for application in East Asian regions, including Korea. In this study, in order to utilize EVC related to an individual's appearance as investigative information, SNPs related to eye shape, hair thickness, skin color, as well as baldness, body type, high myopia, facial shape, acne, and behavioral habits were explored. A total of 50 SNPs were selected, and a targeted amplicon NGS panel capable of amplifying them all at once was developed. Experimental results confirmed the allelic types and frequencies of the 50 SNPs in 14 samples. We plan to use this panel to investigate the correlation between genotype and phenotype using various samples, and to develop methods for interpreting the results.

The Face Stimulus Assessment is an efficient projective drawing test developed by Betts. This paper categorizes scales which Betts suggested into the following five groups: accuracy of painting, color fit, perception of shape, precision of drawing, and space usage. In this paper, a computer algorithm which objectively evaluates these five scales is suggested. The proposed algorithm defines the areas of the lip, eyes, hair, etc. which take on significant roles in the evaluation of the FSA and based on these factors, it calculates the grade of each scale through the main color and color ratio. The consistency of evaluations between the computer algorithm and the art therapist is measured by the Quadratic Weighted Kappa. By providing objectivity and consistency, the computer algorithm is expected to solve the problem of uncertainty found in art therapists' evaluations of projective drawing tests caused by their subjective judgment, experience, and intuition.

We are accustomed to using the word 'beautiful' when we see something, but we don't use the word 'sublime' very often. In fact, these two words have totally different meanings and we can say 'sublime' only for special objects. The notions and objects of sublime have been studied by numerous philosophers ranging from Longinus to Burke and Kant. According to their studies, we can feel sublimity from objects which give us fear, because the sublime is inherent in fear. Therefore, in this study, we considered the sublime in the gothic novel, A Rose for Emily, in which we can find solemn sublimity in Emily's iron gray hair, her black suit, and a red rose which stands for blood. In addition, we can feel sublimity in the image of Emily who is waiting for Homer and the image of Homer's dead body. These kinds of images instill us with fear, but also show us tragic sublimity. The sublime exists in all kinds of literature and, therefore, more studies and analyses of the sublime in literature will likely be conducted.

Aging is accompanied by changes in the body, such as graying hair, wrinkles, and black spots composed of lipid peroxides and proteins. Melanin is a polymer substance produced by an oxidation polymerization reaction from tyrosine, and it determines the color of hair and skin. It has been reported that melanin is synthesized by melanocyte, and its excessive production by reactive oxygen species is associated with aging. The purpose of this study was to determine the direct effects of Musa paradisiaca peel ethanolic extract (MPEE) on antioxidative activity and melanin synthesis. It was observed that the antioxidant activity of MPEE was similar to that of vitamin C, a positive control, in both DPPH radical scavenging assay and reducing power assay. In order to examine cytotoxicity prior to cell experimentation, 3-(4,5-dimethythiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed for B16F1 cells. MPEE was not cytotoxic at $32{\mu}g/ml$ or less. In addition, MPEE increased melanin synthesis in live cells in addition to tyrosinase activity and melanin synthesis in dihydroxyphenylalanine (DOPA)-oxidation assay in vitro. Moreover, MPEE increased melanin synthesis in cells aged by pretreatment with $H_2O_2$. The expression levels of tyrosinase-related protein (TRP)-1, TRP-2, and superoxide dismutase (SOD)-2 by western blot analysis were increased in the presence of MPEE. These results suggest that MPEE could promote the melanin synthesis as an antioxidative substance.

This study was conducted to evaluate the effect of age of laying hens on egg internal and external qualities. A total of 8,300 eggs were randomly collected from 15 grading & packaging (GP) centers, and 50 eggs per farm during April to May in 2015. Age of laying hens ranged from 18 to 65 weeks of age and they were classified into 5 age groups (18~25, 26~35, 36~45, 46~55, and 56~65 weeks). Egg weight increased, but the Haugh unit decreased as the age of laying hens increased. Yolk color was higher in eggs laid from 25~35 weeks of laying hens compared with that of 18~25-weeks-old chickens. The incidence of dirty eggs was highest (P<0.05) in 18~25 week group and remained constant after 26 weeks. Among eggshell defects, speckled and pimpled eggs increased as the age of laying hens increased. The incidence of calcium deposits and misshapen eggs was highest during 18~25 weeks of age and remained constant after 26 weeks. The percentage of total eggshell cracks increased as the age of laying hens increased. Among eggshell cracks, star- and hair-like cracks were frequently noted. The percentage of meat spot was higher than that of blood spot and their incidence was highest among the 56~65 week group. Age of laying hens significantly increased egg weight, incidence of pimpled or speckled eggs, star- or hair-like cracks, and meat spot. On the other hand, a significant negative interaction between age of laying hens and the Haugh unit was noted. In conclusion, our study revealed that the age of laying hens affected internal and external egg qualities.
