The aim of the study was to evaluate the physiological activity of Lycium ruthenicum to investigate their potential as a raw material that can be used in the cosmetic industry. L. ruthenicum fruit extracts were obtained using 70% methanol(LRM) and hot-water(LRW). The DPPH and ABTS radical scavenging abilities were higher in the LRM extract than in the LRW extract. The FRAP value of LRM was about 1.3-fold greater than that of LRW. The polyphenol contents of LRM and LRW were 31.883±1.395 mg/g and 27.748±2.741 mg/g respectively. LRM inhibited the generation of NO in LPS-stimulated RAW264.7 cells. LRM also attenuated the expression of COX-2, PGE2, IL-6, and TNF-α induced by LPS. These results suggests that L. ruthenicum fruits could be use as a source of natural antioxidants and anti-inflammatory agent in cosmetic products.

This study aimed to find an effective intervention measure through establishing the correlation between self-regulation (control over life style) and height growth through neuro-feedback training. 40 elementary students in grades two to four with height growth programs (20 experimental group students, 20 control group students) were examined for the changes before and after undergoing neuro-feedback training. The experiment lasted for three months with one 30-minute training session two times a week. After analyzing the differences in self-regulation among the control group with no neuro-feedback training and the experimental group with neuro-feedback training, the differences in height growth were analyzed. First of all, there were positive changes in self-regulation of the experimental group compared with the control group. Secondly, the experimental group showed larger changes in height growth. In conclusion, neuro-feedback training had positive effects upon the self-regulation that adjusts the acquired factors of height growth, which led to positive effects.

330 Korean adult women were examined the correlation between degree of makeup and makeup satisfaction before/after wearing masks due to COVID-19 and the moderating effect of mandatory/voluntary goal-oriented attitude toward makeup. The study found that lip makeup(p<.001) was significant variable in makeup satisfaction before COVID-19, and eyebrow makeup(0<.002) was significant after COVID-19. Although moderating effect of mandatory goal-oriented attitude, which works between degree of makeup before/after COVID-19 and makeup satisfaction was not significant, but moderating effect of voluntary goal-oriented attitude appeared to be significant before(p<.000) and after(p<.000) COVID-19. And the degree of makeup after COVID-19 was lower than before(p<.000). If one believe that makeup is for one's own satisfaction, degree of makeup can be significant effect on the makeup satisfaction, but actual behavior has shown that degree of makeup has decreased since wearing masks because of COVID-19. I hope this research will be used as marketing material for beauty and cosmetics industry.

This study presents how the recognition of nail care shop's SNS information and nail care service's quality affects to customer's satisfaction, with 257 women who is aged between 20 and 50, with survey. The recognition of nail care shop's SNS information is comprised with understanding, utilization, and loyalty. The recognition of nail care service's quality is comprised with external service, internal service, and the service attitude of employee. All the factors are verified with feasibility study and reliability test. The information about nail care service can be found at the internet and SNS most. The recognition of nail care shop's SNS information has positive effect with the satisfaction of SNS, and the recognition of nail care shop's quality has positive relationship with the satisfaction of nail care service. The various utilization of SNS service with systemic service attitude of employee can lead to positive effect of promoting a nail care shop.

The Spartina anglica is recognized as a highly invasive plant and active eradication methods are required. In this study, we aimed to determine the physiologic activities of Spartina anglica extracts as a cosmetic ingredient. Antioxidant properties were investigated by different chemical methods including radical quenching (DPPH and ABTS), reducing power(FRAP) assay and aerial part of S. anglica(SAA) extract presented the strongest antioxidant activities. The significant cytotoxicity was not observed up to a concentration of 0.5 mg/mL in RAW264.7 cells and NHDF cells. The anti-inflammatory activity of S. anglica belowground(SAB) extract had strong effects on cell-based systems, including LPS-induced NO and cytokines(TNF-a and IL-6) production in RAW264.7 cells. Collagen synthesis and skin hydration gene expression of S. anglica extract showed the highest anti-wrinkle and moisturizing effect in NHDF cells. Results presented in this study tend to show that the ethanol extracts of S. anglica could be exploited as useful-bio-resource for bioactive substances in functional cosmetics.

This study was conducted to determine the cell cytotoxicity, astringency, nitrite oxide scavenging, iNOS protein expression level, pro-inflammatory cytokine, elastase inhibition, and type I pro-collagen synthesis as a functional cosmetics material of Salvia miltiorrhiza root. We prepared the 80% ethanol(SE) and hot-distilled water(SW), respectively. Both SE and SW showed no toxicity from 0.05 to 0.5 mg/mL concentration as a result of MTT assay in NHDF or RAW264.7 cells. In the measurement of astringent effect, SE reveled 74.6% of astringent activity in 10 mg/mL. SE showed that LPS-induced nitric oxide production, iNOS protein expression, and cytokines were inhibited in a dose-dependent manner. Furthermore, two extracts significantly inhibited elastase activity and increased the type I pro-collagen production. Therefore, it is expected that Salvia miltiorrhiza extract is used as a natural material for functional cosmetics that can effectively prevent skin-related inflammation and wrinkles, and aging.

The leaves of Selaginella tamariscina were used for the treatment of many diseases in traditional medicine. In the study, antioxidant, anti-inflammatory, and wound healing activities of the hot-water extract(STW) and 80%ethanol extract(STE) obtained from S. tamariscina were evaluated. As a result, the polyphenol content of STW and STE were 38.108±0.766 mg/g and 17.927±1.064 mg/g, respectively. The DPPH and ABTS radical scavenging activities with the IC50 values of the STW were over 2 times lower than that of the STE. In the MTT assay, RAW264.7 cell viability of two extracts was decreased by about 6% at 1 mg/mL, whereas for HaCaT cell viability increased by 18% at 50 ㎍/mL. In addition, STW and STE suppressed the production of nitric oxide(NO), Tumor-necrosis(TNF)-��. COX-2 and PGE2 in lipopolysaccharide(LPS) induced RAW264.7 cells. Furthermore, the STE showed wound healing effect through the promotion of skin cell migration in TNF-�� stimulated human keratinocytes. These results indicated that the STW and STE have the potential to be used as a new cosmetic active ingredients in skin care.
