Background: There are several options for replacement of the dermal layer in fullthickness skin defects. In this study, we present the surgical outcomes of reconstruction using acellular dermal substitutes by means of objective and subjective scar assessment tools. Methods: We retrospectively reviewed the medical records of 78 patients who had undergone autologous split-thickness skin graft with or without concomitant acellular dermal matrix (CGDerm or AlloDerm) graft. We examined graft survival rate and evaluated postoperative functional skin values. Individual comparisons were performed between the area of skin graft and the surrounding normal skin. Nine months after surgery, we compared the skin qualities of CGDerm graft group (n=25), AlloDerm graft group (n=8) with skin graft only group (n=23) each other using the objective and subjective measurements. Results: The average of graft survival rate was 93% for CGDerm group, 92% for AlloDerm group and 86% for skin graft only group. Comparing CGDerm grafted skin to the surrounding normal skin, mean elasticity, hydration, and skin barrier values were 87%, 86%, and 82%, respectively. AlloDerm grafted skin values were 84%, 85%, and 84%, respectively. There were no statistical differences between the CGDerm and AlloDerm groups with regard to graft survival rate and skin functional analysis values. However, both groups showed more improvement of skin quality than skin graft only group. Conclusion: The new dermal substitute (CGDerm) demonstrated comparable results with regard to elasticity, humidification, and skin barrier effect when compared with conventional dermal substitute (AlloDerm).

In oriental medicine, the skin of the face and the body is the mirror of the viscera and bowels. Skin aging is measured according to the elasticity and glossiness of the skin, which is perceived as a matter of fluid-humor within the realms of oriental medicine. Fluid-humor refers to normal body fluid that makes the skin moist and supple and the hair bright and glossy. If the body is lacking fluid-humor, the hair and skin will be dry and coarse. 'The improvement of fluid-humor (nutrition)' is facilitated based on the oriental physiological change theory for middle-aged women. A new study is therefore necessary to develop oriental herbal cosmetics for young women in their 20s. As yet, there has been no study on the effect of herbal cosmetics formulated for middle-aged women and used by young women in their 20s. This study aims to investigate the effect of 'the improvement of fluid-humor' for the skin of young women in their 20s within the theory of oriental medicine. This kind of study is essential for oriental skin care and the development of diverse oriental herbal cosmetics. To determine the effect of oriental herbal cosmetics on young women in their 20s based on the theory of oriental medicine, which says that a shortage of fluid-humor causes skin aging, this study has examined the skin conditions of young women in their 20s and how satisfied they are with oriental herbal cosmetics through an objective equipment-based measurement and subjective questionnaire survey.

This study analyzed a subject's body reaction and subjective sensation when wearing a gait-assistive rehabilitation robot. The research method measured skin and clothing surface temperatures for 'seating-standing' and 'walking in place' exercises after wearing a gait-assistive rehabilitation robot. In addition, subjective sensation and satisfaction were evaluated on a 7-point Likert scale. The study results showed that the average skin temperature during exercise while wearing the gait-assistive rehabilitation robot was within a comfortable range. However, during the 'seating-standing' exercise, the skin temperature was slightly lowered. Additionally, the clothing surface temperature tended to be lower than the pre-exercise temperature after all exercises. The subjective sensation evaluation results showed that the wear comfort of the waist part was low during mobility/activity. In addition, an overall improvement in the wear comfort of the robot is necessary. The short-time movement of wearing and walking in the gait-assistive rehabilitation robot did not interfere with the thermal comfort of the body. However, the robot needs to be ergonomically improved in consideration of the long wearing time along with improved material that to satisfy overall wearing comfort.

This study was investigated the clothing microclimate, subjective sensation for the improvement of traditional koran high school student uniform so called "Saenghwal Hanbok". For the purpose, casual hanbok school summer uniforms were made. They were made of 4 different textiles materials - P/R, P100, P/C, P/R/S for blouses, P/W, P100, P/R, P/W/F for skirts. Then their clothing microclimate, subjective sensation were tested at room temperature $25{\pm}1^{\circ}C$ and $50{\pm}10%$ R.H. Clothing Microclimates wearing on the blouses were good matched comfort temperature range. Subjective sensations wearing on the blouses were better than those of traditional koran clothes so called "Hanbok" and quite same for western style clothes. Thermal sensations were indicated some hot condition, and moisture sensations were indicated some wet condition but tactile sensations and comfortable sensations were agreeable. The temperatures of the forehead and the breast wearing on the skirts were indicated the same results with the cases of the blouses. Leg temperatures were some lower than the mean skin temperature, the other parts' temperatures were slightly higher than blouses but the mean skin temperatures were satisfied comfortable ranges. Subjective sensations wearing on the skirts were better than those of the other traditional clothes and even Western clothes. Thermal sensations and moisture sensations were resulted the same with the case of blouses. Currently, P/R material and P/W material seemed to be cool and respectively suitable for blouses and skirts in summer among the materials of modernized Korean traditional costumes and school uniforms, since those materials lowered skin temperature. But better, physiologically pleasant materials for summer clothes should be development in consideration of clothing microclimate and subjective sensation.

Purpose. Hypertrophic scarring and depression are the principal problems of bum rehabilitation. This study was done to verify the effects of skin rehabilitation massage therapy (SRMT) on pruritus, skin status, and depression for Korean bum survivors. Methods. A pretest - posttest design using a nonequivalent control group was applied to examine the effects of SRMT for 3 months in a group of 18 bum survivors. The major dependent variables - including pruritus, objective and subjective scar status, and depression - were measured at the beginning and at the end of the therapy to examine the effects of SRMT. Results. Bum survivors receiving SRMT showed reduced pruritus, improved skin status, and depression. The remaining scar also showed improvement in skin pigmentation, pliability, vascularity, and height (compared to the surrounding skin) as measured on the Vancouver Scar Scale (VSS). Conclusions. The findings demonstrate that SRMT for bum survivors may improve their scars both objectively and subjectively, and also reduce pruritus and depression.
