Ascorbic acid (Vitamin C) has been widely used in skin care formulations. Due to its remarkable effects on anti-oxidation, collagen biosynthesis and whitening, ascorbic acid is considered as an effectible anti-aging active ingredient. But, the instability problems of ascorbic acid in cosmetic formulation such as oxidation, browning and changes in smell is the difficult issue to be overcome for the application of high concentration of ascorbic acid. We tried to stabilize the ascorbic acid in non-aqueous liquid formulation that contains polyol solvent at first. The non-aqueous system was effectible to reduce oxidation. But, ascorbic acid was crystallized in the non-aqueous formulation at the low temperature below $5^{\circ}C$. We tried to develop way to stabilize the ascorbic acid in aqueous solutions to solve the crystallizing problem. In this study, we search the optimal ratio of antioxidant combination, such as zinc sulfate, glutathione and curcuma longa (turmeric) root extract. Formulations were stored at - $16^{\circ}C$, $5^{\circ}C$, $25^{\circ}C$, $40^{\circ}C$, $50^{\circ}C$ and cycle($5-40^{\circ}C$) (in incubator) for a period of eight weeks to investigate their stability. In the stability analysis, the test parameters consisted of color, scent, phase separation and sedimentation. Ascorbic acid stability was checked by HPLC analysis.

This study includes online and offline surveys of 255 people conducted from March 11-29, 2021, into women's preferences in esthetic shops, and examines their level of satisfaction with skin and beauty home care. The collected data were analyzed using SPSS 25.0 to obtain technical statistics such as Cronbach's α and a frequency analysis, and applied a chi-square test and one-way ANOVA. According to the results on preferences in esthetic shops, the largest number of respondents (56.1%) said they use professional esthetic shops, but those in their 20s and office workers (57.1%) preferred dermatology clinics. When choosing esthetic shops, the importance of employee skill (skilled, trendy) was high (38.8%), and in skin care, the importance of knowing basic cosmetics use (M=4.47), such as cleansing and functional cosmetics (M=4.20), was very high. According to results on the current status of home care for skin beauty, other factors of highest importance (M=4.50) were in terms of marriage, being a university graduate (M=3.84), and experience in a service job (M=4.06). As a result, there is a need to develop programs not only specializing in skin beauty but also combining professional esthetic shops and home care.

This study examined the importance of the skin care source on the consumer's general characteristics (lifestyle, residential district and income). The questionnaire survey results showed that women in their twenties choose dermatologic clinics as the best source for skin care. The three-way ANOVA using three variables (lifestyle, residential district and income) showed notable differences between the dermatologic clinic, newspaper?magazine, family?friends, and internet sources. Some suggestions for a marketing strategy were made. For example, newspaper?magazine targeting high income consumers is a good means for dermatologic clinics in Seoul and the Internet is better than other sources for other industries in Daejon.

Purpose: The purpose of this study were to develop a new restraint for the intensive care units (ICU) and to investigate the application effect in comparison with a control group using existing restraints. Method: A non-equivalent control group non-synchronized quasi-experimental research design was used. The participants were 40 (control 20, experimental 20) patients who were recruited by convenience sampling the ICU of a university hospital. To avoid contamination of the experiment, data for the control group were collected prior to the experimental group. Measurement variables were edema and skin damage (redness and abrasion) at the application site, and nurses' perceived convenience in applying restraints. Results: Three days after applying the restraint, amount of edema at the application site was small and incidence of skin damage decreased in the experimental group in comparison with the control group. Also, score for application convenience measured by the nurses was higher in for the newly developed restraint than for existing restraints. Conclusion: Results indicate that the newly developed restraint has lower effects such as edema and skin damage and is more convenient compared with existing restraints, and is therefore recommended for patients in the ICU.

As interest in skin care increases, this study aims to contribute to the development of the beauty self-care market by providing basic data through the measurement of the oil and moisture skin condition of women in their 20s and 30s. The study was conducted from November 27, 2020 to January 31, 2021, with 20 women in their 20s and 30s divided into 4 groups, A~D, by age, 5 per group. Skin measurements were taken four times at 4 hour intervals at 0H, 4H, 8H, and 12H based on the first measurement that was taken within 30 minutes after waking up, and the oil and moisture indices were observed over time. As a result, both T and U zones showed significant differences in moisture levels over time, with no difference between groups for both T and U zones. Moisture decreased the most between 0H to 4H, and moisture changed the least between 4H to 8H. Changes in moisture increased the similar at 0H and 12H. The oil condition changed more irregularly compared to moisture over time, but all groups showed lower oil content in the U-zone compared to the T-zone. Overall, the facial oil and moisture conditions of women in their 20s and 30s changed over time, indicating that the skin changes in real time. The fact that the skin data, which was measured in the primary activity living environment, can be used as basic research data in the beauty self-care market is meaningful.

This study is to examine the relation between self-consciousness and appearance management behavior; to grasp the appearance management behavior depending on self-consciousness which older women feel personally; to understand their needs more deeply; and to give support in planning and conducting marketing strategies effectively in the beauty and fashion market. The subjects of this study were aged women ranging 55 to 69 in age, living in Daegu and Geongsangbukdo. 500 questionnaires were distributed and 397 questionnaires out of 440 returned were used in the data analysis. The results through statistic analyses are following: 1. Among older women, the higher social self-consciousness group appeared to pursue six types of appearance management behavior(i.e., weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior) much more than the lower social self-consciousness group. 2. Compared with the lower private self-consciousness group, the higher private self-consciousness group appeared to care for not only weight body-shape care but also skin care, cosmetic care, and cosmetic surgery, clothing behavior with more interest in ordinary times. In terms of hair care, though, there was no significant difference between the higher private self-consciousness group and the lower private self-consciousness group. 3. There was no statistically significant difference between the higher social anxiety group and the lower social anxiety group in weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior.

Purpose: This study was performed to compare the effects of standardized peristomal skin care (SPSC) and crusting technique (CT) on the peristomal skin of ostomates. SPSC was developed by a consensus among the expert group based on a comprehensive review of the relevant literature and hospital protocols. Methods: A randomized controlled pilot trial with 2 parallel arms was used. A total of 81 ostomates, who were recruited from a tertiary hospital, completed the baseline, 1-month, 2-month, and 3-month follow-up (SPSC group, n=45; CT group, n=36). SPSC consisted of water cleansing and direct application of ostomy appliances. CT involved crusting hydrocolloid powder and patting with water sponge or protective barrier liquid film. The outcomes of the study were assessed by skin problems, such as discoloration, erosion and tissue overgrowth; the domains of the evaluation tool used in examining the peristomal skin. A generalized estimating equation model was used to examine the effects according to time and group. Results: In both SPSC and CT groups, the likelihood of occurrence of discoloration (OR, 1.99; 95% CI, 1.61-2.46), erosion (OR, 1.87; 95% CI, 1.55-2.25) and tissue enlargement (OR, 1.94; 95% CI, 1.36-2.77) increased with time. There was no significant difference in discoloration between the groups, whereas the probability of erosion (OR, 0.38; 95% CI, 0.16-0.89) and tissue overgrowth (OR, 0.09; 95% CI, 0.02-0.55) was lower in the SPSC group than in CT group. Conclusion: SPSC was sufficient in preventing peristomal skin problems of ostomates compared to the CT.
