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.

This study was performed to provide basic for predicting the usefulness of Gastrodiae rhizoma(Cho'nma) as a food material for oriental applied diet therapy(YackSun). Thus, Gastrodiae rhizoma was used to develop a traditional Korean snack, Dasik. As a useful food resource, Gastrodiae rhizoma along with Cortex fraxini powder, was used to prepare Dasik. Cho'nma powder was added to the Dasik 63.2%(Dasik-1), 42.2%(Dasik-2) and 21.0%(Dasik-5) of Cho'nma powder to Dasik in one piece(5 g). The moisture and crude ash contents of the Dasik-1, 2 and 3 were analyzed. Physio-chemical analysis and a sensory test were also performed on the Dasik. Moisture and crude ash contents of Dasik-1 were 20.16% and 0.65%, respectively. Moisture and crude ash contents of Dasik-2 and Dasik-3 were 22.92 and 27.17% and 0.49 and 0.23% respectively. from the color test, the t value of Dasik-1 was found to be significantly low but the b value of Dasik-1 significantly high compared with the other preparations. The addition of Cho'nma had a tendency to impart high hardness, fracturability, gumminess and chewiness. Therefore, the addition of Cho'nma made the texture of Dasik denser. From the sensory test, the color, chewiness and overall acceptability of Dasik-1 were found to be significantly high. In conclusion, the addition of 63.2% Cho'nma per piece would be a useful recipe to enhance the quality of Dasik, and the flour Cho'nma showed better result than the Dasik-2 and Dasik-3.

The HyeolRacRon(血絡論) of the YoungChu(靈樞) is one of the section associate with the study of bloodletting(depletion of blood) by acupunture. The bloodletting therapy, one of the treatment of Oriental Medicine, has been advanced in civilization. By studying of this section, I could find some conculution as follows: 1. It is the superficial venules(血絡) that has been included blood stasis which has been interrupted by pathogenic factor(邪氣), and still could not enter into the meridian's line. 2. When bloodletting therapy, we should carefully study of patient's health condition, because doctor's missed acupuncure leads to very serious side effects. 3. External shape of HyeolRac(血絡) is like acu-niddle or muscle, so its thickness and location were not fixed position, its color is redish, and its quality is hard. 4. It is reason of heating that fixation of acu-niddle and muscle fiber.

Aerobic exercise affects cerebral circulation, action of neurotransmitters, glucose, oxygen, and energetic substances and influence on the central nervous system for cognition. This study suggests that both the intensity of exercise and the level of cognitive task need to be considered. Computerized neurobehavioral testing is a more effective method, compared to conventional methods, of neuropsychological testing when measuring cognition objectively, in cases that we found. The intensity of 80% max HR had effect on more complex tasks such as 3 Digit Addition and Digit Span Backward, and the intensity of 65% max HR had an effect on more simple tasks such as Color Word Vigilance and Digit Span Forward. We can assume that different intensity of aerobic exercise might involve specific areas of the brain as they could have different sensitivities, so further studies measuring regional cerebral blood flow or electroencephalogram are needed to confirm the results.

This research examines the interrelation of clothes, colors and sentiments based on clothes and colors that stimulate sentiment. This study provides data that is useful to color therapy by means of clothes as medium. The survey for this study targeted 200 Pusan National University students who analyzed the colors of association and clothes colors for nine positive vocabularies (passion, love, warmth, happiness, interest, softness, comfortable, freshness, and coolness) and six negative vocabularies (anger, fear, despair, nervous, gloomy, and loneliness). The data collection process used 120 standard colors as represented by Munsell's basic 10 colors (R, YR, Y, GY, G, BG, B, PB, P, RP) as chromatic colors classified into eleven tones of colors (V, S, B, P, VP, LGR, GR, L, DL, DP, DK) and achromatic colors divided into ten steps of brightness N1-N10. The results of the research are as follows. First, the warm class of colors were significant in the colors of association with positive sentiment and the cold class of colors were significant in the sentiment of refreshment and coolness. In addition, bright and clear colors (like V, S, VP, P) were associated with color tones. Second, the low bright achromatic colors were generally high for the colors of association with negative sentiment; in addition, the color of R, PB, P (as achromatic colors) were also significant. In addition, sober and dark tones (like GR, DL, DK, DP) were significant in color tones. Third, the interrelation between positive sentiment and clothes colors shows that colors of association were mainly used for upper garment colors. Similar colors against upper garments were used together for bottom garment achromatic colors and complementary colors; therefore, bottom garments play a subsidiary role in the concept of coordination with upper garments.

Background and Objectives Skin and soft tissue defects can be treated according to a range of strategies, such as local flap, skin graft, biological dressing, or free flap. On the other hand, free tissue transfer usually leaves a distinct scar with an inconsistency of color or hypertrophy. This problem is highlighted if the defect is located on the face, which could have devastating effects on a patient's psychosocial health. Materials and Methods The authors used an erbium : yttrium-aluminum-garnet (Er:YAG) laser to resurface the free flap skin and match the color with the surrounding facial skin. This study evaluated the effectiveness of laser skin resurfacing on the harmonious color matching of transferred flap. Patients who had undergone laser resurfacing on facial flap skin between January 2014 and December 2018 were reviewed retrospectively. An ablative 2,940-nm fractional Er:YAG laser treatment was delivered to the entire flap skin at 21 J/cm² with the treatment end-point of pinpoint bleeding. Several months later, the clinical photographs were analyzed. The L^*a^*b^* color co-ordinates of both the flap and surrounding normal skin were measured using Adobe Photoshop. The L^*a^*b^* color difference (ΔE) for the scar and normal surrounding skin were calculated using the following equation: ${\Delta}E=\sqrt{({\Delta}L)^2+({\Delta}a)^2+({\Delta}b)^2}$ Results All five patients were satisfied with the more natural appearance of the flaps. The ΔE values decreased significantly from the pre-treatment mean value of 19.64 to the post-treatment mean value of 11.39 (Wilcoxon signed-rank test, p = 0.043). Conclusion Ablative laser resurfacing can improve the aesthetic outcome of free tissue transfer on the face.
