Background: There have been no reports of studies on the effect of a combination of myofascial relaxation technique and passive stretching on the lower extremity body shape of working women. Purpose: This study aimed to examine the effects of myofascial relaxation technique and passive stretching on body composition and body composition analysis (intracellular fluid, skeletal muscle mass, body cell mass), etc. Methods: The subjects of this study were 30 women at a body shape management center who had many problems with their subjective lower extremity body shape. Fifteen subjects were in the experimental group and the control group. The experimental group applied the fascial relaxation technique twice a week for nine weeks. The control group conducted stretches by themselves at least twice a week according to the active stretching instructions. The ANOVA program analyzed the data. Results: In the experimental group, intracellular fluid (p < .05), skeletal muscle mass (p < .048), and body cell mass (p < .047) were significantly increased. Conclusion: The lower extremity edema of working women decreased

This study was conducted to measure the antimicrobial activity and antiseptic effect of Smilax china root extracts against Propionibacterium acnes and to develop natural antimicrobial extracts as an alternative for synthetic preservatives, which have recently been controversial. Extracts were obtained from dried Korean Smilax china root at room temperature using two solvents, distilled water and 95% EeOH, separately. According to the results of this study, the antimicrobial effect of Propionibacterium acnes 3314 and Propionibacterium acnes 3320 against Propionibacterium acnes was outstanding. In particular, the clear zone of the extract using distilled water showed the highest activity with 16.61 mm. As for the result of the collection of contaminated skin sample, the clear zone was 24.48 mm. This indicates that Smilax china root extracts show a high activity against skin flora as well as a high antimicrobial activity against Propionibacterium acnes. In conclusion, it is confirmed that Smilax china root extracts can be used as raw materials for cosmetics that have antimicrobial activity and antiseptic effect, and it is expected that Smilax china root extracts will be used as basic materials for the development of future natural preservatives.

In suddenly changing multimedia periods, department store not only plays the role of local culture centre but also meets keen competition in working out marketing strategies, especially in the field of differentiating Promotion Surroundings Image, in order to cope with the varied consumers' pattern according to customers' pursuing new lifestyle. In particular, cosmetic stores located in the first floor of the department store have high sales rate in spite of its comparative small area, because cosmetic stores have been much essential to women's daily life who are very strong for desiring the Beauty and also in them men's buying trends have been upwards speedily. The color and P.P.(Point of Sale Presentation) of the cosmetic store design are preferred after the quality and the price of the goods, staff's services by this survey of female clients' attitude to buy cosmetics at department store in Seoul. So that cosmetic companies seem to be needed to offer the differentiated color code in each brand and display the goods' P.P.(Point of Sale Presentation) intensively to promote the sales effectively. This thesis aims at suggesting the way how cosmetic firms get and enhance their goods' competitiveness when they develop their visual merchandising strategy by considering each brand's attribute and customers' life style by age, preference factors for buying the goods through showing high qualified sonics in their differentiated displayed stores.

To investigate the clinical aspects of CHT in atopic dermatitis (AD) treatments, the effect of CHT in anti-oxidative and anti-inflammatory cytokines were tested. 100% or higher cell viability was observed in all tested groups from 25 to 200 ${\mu}g/m{\ell}$ using Raw 264.7 cells. CHT showed dose-dependent DPPH scavenging activity, with more than 90% scavenging activities at 800 ${\mu}g/m{\ell}$ concentrations. CHT showed dose-dependent suppression activity of ROS production, especially at 200 ${\mu}g/m{\ell}$ of 37.5%. CHT decreased NO production activity, with significant decrease of 33.2% at 200 ${\mu}g/m{\ell}$. IL-6, MCP-1, TNF-${\alpha}$ production rate were decreased by approximately 25% when Raw 264.7 cells were treated with LPS and with CHT of 200 ${\mu}g/m{\ell}$. Also, IL-$1{\beta}$ production rate was decreased by 25% at 100 ${\mu}g/m{\ell}$. The results above indicate that CHT significantly reduces the effect of oxidative and inflammatory cytokines. The use of CHT in dermatitis can be widely suggested.

In this study, the antioxidant and anti-inflammatory properties of Silvetia siliquosa extracts were identified. Antioxidant experiments included polyphenol concentration measurements, flavonoid concentration measurements, DPPH experiments, ABTS experiment NO experiments, and FRAP experiments. For polyphenols, 54.85 ± 2.79 mg/g was shown. Flavonoids showed 18.70 ± 5.26 mg/g. The DPPH experiment showed an antioxidant function of 3.950 mg ascorbic acid/g extract, the ABTS experiment showed an antioxidant function of 7.418 mg ascorbic acid/g extract, and the NO experiment showed an antioxidant function of 6.056 mg ascorbic acid/g extract. In FRAP, 1 mg of the moxibustion extract showed a reduction of 3.633 ± 0.280 ㎍ of ascorbic acid. In the meantime, cell experiments showed cytotoxicity and anti-inflammatory functions against inflammation induced by LPS. In cytotoxicity experiments, Silvetia siliquosa extracts showed a cell survival rate of more than 80% at all concentrations, and an inflammatory inhibition of 26.94±0.52% at a concentration of 100 ㎍/mL. These results indicate that Silvetia siliquosa extract is available as an anti-inflammatory cosmetic material.

Due to COVID-19, modern people have come to prefer natural substances as anxiety due to harmful environments and various stimuli has increased. Therefore, in order to find out the appropriateness of hibiscus, which is recognized as a non-toxic plant in traditional medicine, as a natural cosmetic material, the antioxidant effects (polyphenol, flavonoid, DPPH, ABTS) of hibiscus extract were studied, and the following results were obtained. First, the total polyphenol of hibiscus was found to be 433 ㎍/mL when the HSE was 100%. Second, the total flavonoids showed high antioxidant capacity at 488 ㎍/mL in 100% of the HSE. Third, the DPPH radical scavenging ability was found to be 94.04% in the undiluted HES and 89.54% in the diluted HSE 20%. Fourth, the ABTS radical scavenging ability was 98.95% in 100% of the HSE stock solution and 94.84% in the diluted HSE 20%, respectively, showing a high scavenging ability of more than 90%. As a result of these studies, it is thought that the hibiscus extract can be used as an antioxidant raw material for natural cosmetics in the future.

This study investigated the effects of coumarin, a flavonoid known for various physiological activities like antiviral, anticancer, and antibacterial properties, on anti-oxidants and anti-inflammatory processes, aiming to explore its application in functional cosmetics. The results are as follows: Cell toxicity experiments using RAW 264.7 cells showed no significant cytotoxicity for coumarin at any concentration, indicating its safety for skin application. Observing coumarin's antioxidant activity through DPPH radical scavenging showed concentration-dependent effectiveness, though not significantly varied with concentration. The inhibition of silica-induced ROS production in cells was concentration-dependent. Both NO production inhibition and histamine release measurements showed concentration-dependent suppression. These findings suggest that Coumarin can be effectively used as a natural ingredient in cosmetic development for its antioxidant and anti-inflammatory properties.

Beyond the mid-2010s, there has been increasing cases of using 'Reminiscence' as a trigger for recalling 'Past' in pre-production process of creative contents. In previous researches on this phenomenon, it has been recognized that retro, recall, compassion, and memory are similar. In order to look closely to grasp the psychological tendency of the contents user in detail, the study about 'Reminiscence' was conducted. The researcher analyzed 'Reminiscence' as a process of restructuration based on the experience and desire of the person individual which were derived from the past and further analyzed it as a lack of desire due to the time can never return. The study hopefully can make a balance against the cutting edge content distribution technology biased production tendency.
