Usually, the skin pigmentation detection and diagnosis are made by clinicians. In this process it is subjective and non-quantitative. We develop an approach to detect and measure the different pigmentation lesions base on computer vision technology. In the paper we study several usually used skin-detecting color space like HSV, YCbCr and normalized RGB. We compare their performance with illumination influence for detecting the pigmentation lesions better. Base on a relatively stable color space, we propose an approach which is RGB channels vector difference characteristic for the detection. After the object region detection, we also use the difference to measure the difference between the lesion and the surrounding normal skin. From the experiment results, our approach can effectively detect the pigmentation lesion, and perform robustness with different illumination.

Objective : Etiologically, stress is a important factor to immune system and skin disease. Human body is controled to keep his homeostasis from stress by autonomic nerve system. So we investigated autonomic nerve balance and stress level of patients with skin disease by heart rate variability(HRV) test. Research Methods and Procedures : Fifty two patient(from 15 years old to 35 years old) who visited Dept. of Oriental medical Dermatology, Kyunghee university at first and had an examination by HRV test, were selected as the subject of our study. We checked items of HRV test(such as SDNN, RMSSD, VLF, LF, HF, TP, norm-LF, norm-HF, LF/HF ratio, LnHF and LnHF), and analyzed time and frequency domain by sex, age, onset, color on end of patient's tongue, sweating and sleep condition. Results and Conclusion : Men showed significant higher SDNN, RMSSD, LF, norm-LF, norm-HF, LF/HF ratio, LnLF and LnHF than women(p <0.05). Patients who were attacked by skin disease within 6 months, showed significant higher TP and VLF than over 6 months(p <0.05). Patients with normal color on the end of their tongue showed significant higher TP and VLF than with flare color. We analyzed correlation to color on the end of tongue and RMSSD. Prevalence risk(RMSSD <20ms) in the case of normal color on the end of tongue was 5 times as high as in the case of flare color(p <0.1). And we analyzed correlation to age and LF/HF ratio. Prevalence risk(LF/HF ratio <1) of patients from 15 years old to 25 years old was 1.467 times as high as from 26 years old to 35 years old(p <0.1).

Man's search for beauty has been going on from prehistoric time until today, and the pursuit of beauty has been progressing, regardless of the times, as a human psychological desire. In the search for beauty, hair and make-up have been subjects of interest for a long time, but the development of designs for these two aspects are still behind compared to other areas. Therefore, this study aims to propose various new and creative hair and make-up designs and to suggest their possible development. Using existing literature, this paper studied the skin color and hair color of Koreans that had been studied in earlier papers. It also aimed to understand the hair color and hair color images that are suitable for each skin color, classify the modern hair and make-up trends into different images - natural, surrealistic, minimalist, and cyber look, and also analyze them. Actual hair and make-up were also designed based on these images. To depict the natural image, the make-up was made intentionally dark as the skin color; natural materials were used for hair decoration; brown and yellow were used for the eye shadow to express the natural and romantic image of autumn, in general. Second, in the work expressing the surrealistic image, the hair was creatively decorated with a collage of various objects; yellow, green, and red eye shadows and lip expression were used to visually achieve the surrealistic fantasy look. Thirdly, in the work expressing the minimalist image, hair style with bangs without any hair decoration was used; make-up colors were minimized as well, creating a generally simple image. Finally, for the work expressing the cyber image, metallic material decoration was used on a puff-up hair style; the cyber image was emphasized through the use of graphical elements in the make-up.

Dresses reflecting human aesthetic consciousness are used as a way of expressing the inner desire of human beings. The desire to attract the opposite sex through sexual appeal among the human inner desires is the one innate characteristic that all human beings have. We may say that the $See-through$ look emphasizes a sense of softness and femininity by exposing the skin and expresses bodily beauty by way of using see-through cloth. It is a fashion style that can express sexual appeal and eroticism of female most effectively. In this study, after observing the motivation of dress wearing and $See-through$ look in the perspective of bodily concept and eroticism, colors of $See-through$ look shown in the $Pret-a-Porter$ Paris S/S collection from 2006 and 2007, a fashion style expressing eroticism was newly re-analyzed as romanticism and glam look particularly in 60, 80s compared with other times were re-created and evaluated. As a result of analyzing colors of the $See-through$ look, Yellow Red(close to skin color) was revealed to be the highest( 31.3%), followed by Red(9%), Purple Blue(7.2%), Yellow(7.2%), Purple(5.4%), respectively and in terms of color tone, pale and gray tones that have a sense of femininity and softness was revealed to the highest(20%) followed by ltg(11%) and dkg(9%). We may find the meaning of this study in analyzing colors of the $See-through$ look, and the typical look of eroticism, which has never been tried before. It is required to identify chronological color features of the $See-through$ look and the diversified characteristics of skin colors expressed in them to prepare useful data by which a sense of the $See-through$ look can be utilized for color coordination through the relationship between skin tone and dress by pursuing a more detailed method based on the result of this study.

Objectives : Cupping therapy has been used as various treatment methods in oriental medicine clinic for a long time. Specially, Cupping stimulation caused skin hyperpigmentation which has been used as diagnosis method for extravasated blood & inner organs functional disease. But it was difficult to quantitatively measure and analyze the interrelation between extravasated blood and skin hyperpigmentation. The aim of this study is to measure the acupoint's RGB and melanin change pattern by stimulating under fixed 80kPa negative pressure and to evaluate the extravasated blood. Methods : To evaluate extravasated blood, 10 acupoints (left/right BL13, BL15, BL18, BL20, BL23) were stimulated by treatment 80kPa negative pressure for 1 minute. And then we measured the acupoints' skin color change patterns using the color meter, followed by RGB analysis and melanin change pattern. Results and Conclusions : We could observe the correlation of the acupoints' skin color condition related with RGB change pattern. All acupoints' color change degree were different. Regardless of acupoints' color degree due to extravasated blood, we observed in common the fact that RGB values decreased after stimulation and steadily increased according to time. We observed that melanin index increased after stimulation and recovered before stimulation-condition after the lapse of time. In other words, we confirmed the correlation between raised color change degree and $L^*a^*$ index change pattern. Therefore we observed the possibility of charting the $L^*a^*$ index following extravasated blood.

It has been known that the color of skin reflects the blood flow within. In lips, the capillaries close to the skin surface are numerous; hence lips are redder than the rest of face. However, dermatological research on lips is not as advanced as research on facial or body skin, and little was known about the relationship between relatively dull-colored lips and skin blood flow. The physiological differences between colorful and dull-colored lips were studied by a two-dimensional laser Doppler blood flow analyzer, a spectrometer for the measurement of the degree of oxygen saturation, and a confocal microscope for observing inside lips non-invasively. Dull-colored lips and the corner of lips (dull-colored compared to the center) showed relatively poor blood flow and lower oxygenated hemoglobin. It was found that colorful lips (generally the young) had a blood flow that tended to run straight in parallel with the skin surface. This unique blood-capillary structure can express clear red blood. Those with dull-colored lips had lost this unique structure. Their blood ran perpendicularly from the deep of the skin and down back again into the deep part as like the blood circulation patterns of facial skin. Therefore, the lips of the latter group had fewer blood capillaries near skin surface in the lips than that of the colorful-lips group. A lipstick containing a-glucosyl-hesperidin, which is derived from certain citrus fruits and can enhance blood circulation, was applied for evaluating its effects. Blood flow was increased 30 min after the application. After two weeks of daily application, the lips' condition became noticeably less dull. These findings suggest that the decrease of blood flow in dull-colored lips is caused by the loss of the unique capillary structure and the use of the lipstick to increase blood flow can give a vivid color to lips.
