피부미용사는 한국 표준 직업 분류에서 피부미용사 또는 피부관리사로 분류되며 질병상태가 아닌 피부미용관리 서비스를 제공하며 피부 관리 업무를 수행하는 직업이다. 이러한 일들을 수행하면서 피부미용사들은 손가락 및 손목, 어깨 등을 장시간 동안 지속적이며 반복적으로 사용하게 됨으로써 근골격계 질환과 관련된 위험에 노출되어 있는 것이 현실이다. 1981년 YWCA를 통해 첫 교육을 시작한 이래로 2008년에는 피부미용사 국가 자격증이 헤어미용과 분리되면서 더욱 전문화, 세분화, 다양화 되어 가고 있다. 따라서 본 연구에서는 피부미용사를 대상으로 첫째, 작업 자세에 따른 통증의 부위, 통증정도 등을 조사하고 둘째, 얼굴 및 전신관리 작업자세와 근무환경이 근골격계 질환에 미치는 영향을 조사하고자 한다. 본 연구의 대상과 범위는 광주지역의 안면관리와 전신관리를 시행하고 있는 5인 이상의 피부 관리실에서 현재 근무하는 피부미용사를 대상으로 2010년 12월 1일부터 12월 30일까지 약 4주간에 걸쳐 실시하였으며 총 300부의 설문지를 배포하여 총 278부를 최종 분석에 사용하였다. 본 연구의 자료는 SPSS WIN 13. 0 프로그램을 이용하여 기술통계분석, 교차분석, t-test분석을 실시하였으며 그 결과는 다음과 같다. 첫째, 피부관리 작업 시에 통증을 느끼고 있는 관리사가 전체 278중 200명(71. 9%)으로 나타나 상당부분 작업을 통해 통증을 느끼고 있음이 나타났다. 둘째, 부위에 따른 통증 유병율은 전체 통증을 느끼는 손, 손목, 손가락이 가장 높게 나타났으며 다음으로 목, 어깨, 허리, 팔과 팔꿈치, 다리와 발 순으로 나타나 통증을 느끼는 피부미용사 중 손, 손목, 손가락에 가장 많은 통증을 느끼는 것으로 나타났다. 셋째. 피부관리 작업자세 중 안면 피부미용 작업자세에서는 미용기구를 이용할 때 손목이 꺽이거나 힘이 들어가는 자세(t=2. 29, p<0. 05)에서 유의한 영향을 미치는 것으로 나타났다. 전신미용 자세에서는 양손에 힘을 주어 손목회전을 많이 사용(t=2. 25, p<0. 05)하는 것과 미용기구를 이용할 때 손목이 꺽이거나 힘이 들어간 자세로 작업(t=2. 75, p<0. 01)자세에서 유의한 영향을 미치는 것으로 나타났다. 넷째, 근무환경인 직무환경, 직무량, 스트레스가 근골격계에 미치는 영향을 검증한 결과 직무환경(β= 0. 140, t=1. 490, p>0. 05)은 유의한 영향을 미치지 않는 것으로 나타났으나, 직무량은(β=0. 261, t=2. 009, p<0. 05), 스트레스(β=0. 255, t=2. 179, p<0. 05)는 근골격계에 질환에 유의한 영향을 미치는 것으로 나타났다. 본 연구 결과 피부미용사의 70% 이상이 근골격계 질환 증상을 경험하고 있으며 작업 자세와 관련성이 매우 높음을 알 수 있었다. Estheticians are classified into estheticians and skin care experts according to Korea Job Classification who provide skin care and control services. While working, they repetitively use their fingers, wrists and shoulders for such a long time, which causes them to be exposed to musculoskeletal diseases. The first education began at YWCA in 1981 and the national esthetician certification system was separated from the beauty care in 2008. Therefore, this study investigated areas, degrees and periods of pain according to estheticians` working postures and the effect of their working postures in controlling faces and bodies ion their pain in order to present methods to enhance work efficiency and health through proper working posture. The subjects of the study were estheticians who were working at esthetician shops which provided face and body care services with more than five employees in Gwangju and the period ranged from December 1, 2010 to December 30, 2010. For the study, a total of 300 copies of the questionnaire were distributed and 278 were used for the final analysis. The data collected were analysed through a descriptive statistic analysis, cross-tabulation and a t-test with a use of SPSS WIN 13.0 and the results are presented as follows: First, it was discovered that 200(71.9%) of the subjects had pain while working. Second, prevalence rates of pain were highest in hands, fingers, and wrists followed by necks, shoulders, waists, elbows, legs and feet. It indicates that the subjects had the most pain in their hands, wrists and fingers. Third, in respect to face care working posture, bended or burdened wrists(t=2.29, p<0.05) had significant effect on their pain. For the body care posture, turning of wrists with burden on their both hands (t=2.25, p<0.05) and use of bended or burdened wrists using care tools (t=2.75, p<0.01) had a significant influence on their pain. Fourth, as a result of examining the influences of working environment, working quantity and stress on pain, it was discovered that working environment had no significant influence on pain on the musculoskeletal system (β=0.140, t=1.490, p>0.05), but working quantity(β=0.261, t=2.009, p<0.05), and stress(β=0.255, t=2.179, p<0.05) had significant influences on the musculoskeletal system. The results of the study indicate that more than 70% of the subjects had musculoskeletal diseases and the diseases had close relations with working posture.

This study examined the physiological activities of the skin through utilization of Codonopsis lanceolata and Fermented C. lanceolata extracts to determine if they could be used as cosmetic ingredients. The following results were obtained: According to a measurement of polyphenols and flavonoid content, 32.7±0.88 ㎎/g of polyphenols and 1.41±0.31 ㎎/g of flavonoid were observed in fermented C. lanceolata extract. In terms of the DPPH radical scavenging activity, 41.11±0.77 μg/mL was observed at 1000 μg/mL of fermented C. lanceolata extract. In terms of the nitric oxide scavenging activity as well, 80.21±0.90 μg/mL was detected at 1500 μg/mL. According to measurement of tyrosinase inhibition activity, 7.33±2.60% was found at 100 μg/mL. Therefore, the fermented C. lanceolata extract was higher than the C. lanceolata extract in terms of tyrosinase inhibition activity. According to measurement of the antimicrobial effect on skin bacteria such as P. acnes, S. aureus and S. epidermidis, in addition, a clear zone was observed with 9.580 ±0.39 8.10±0.42 and 8.00±0.14 at 5 mg/disc. This shows that the C. lanceolata extract was greater than the fermented C. lanceolata extract in terms of antimicrobial effect. According to measurement of toxicity on the B16F10 melanoma cell, survival rates were fairly low at some concentration levels, but they were not severe enough to cause toxicity. Based on the results above, this study has confirmed that fermented C. lanceolata extract can be utilized as a cosmetic ingredient because it is higher in physiological activity than the C. lanceolata extract.

This study investigated the influence of hair properties, food against alopecia, scalp and hair management types on alopecia to present a healthy scalp and hair management program. For the purpose, this study interviewed 353 women living in Gwangju and adjacent areas using a questionnaire and the data collected were analysed through a descriptive statistical analysis and a multi-regression analysis with uses of SPSS WIN 11.0. The results are presented as follows: First, as a result of analysing difference in alopecia according to scalp and hair management types, it was discovered that there was a difference in presence of alopecia according to the mean frequency of weekly shampooing (t value =-2,474, p<0.01) and the frequency of hair style change (t value = 2,568, p<0.01). Second, when this study analysed the causal effect of hair properties, food against alopecia, scalp and hair management types on alopecia, it was discovered that the more food containing protein, the lower possibility of alopecia. For properties of hair, the more dandruff, oil, and gray hair the subjects had, the higher rate of alopecia they had. However, the more volume of hair, the lower influence on alopecia. Scalp and hair management types were not related with alopecia. Therefore, it was demonstrated that protein processed food such as milk and Tofu prevents alopecia as it is good for scalp and hair. In conclusion, in order to maintain healthy scalp and hair and prevent alopecia, scalp and hair management status should be exactly identified with practice of right hair management and diet.

To show the anti-oxidation effects of Phragmitis rhizoma extract, this study investigated the composition ratio of its components, thecontent of the anti-oxidative materials polyphenol and flavonoid, and the DPPH scavenging effect and SOD activity to measure anti-oxidative activity. It was shown that P. rhizoma is composed of the following: 77.88% natural fiber, 9.15% moisture, 6.62% protein, 5.95% minerals ash, and 0.40% natural fat. The content of polyphenol in the hot water extract was 4.59±1.60mg/g and 10.13±1.81mg/gin the ethanol extract, and that of flavonoid in the hot water extract was 26.76±0.55mg/g and 28.65±1.45mg/g in the ethanol extract. Therefore, in P. rhizoma extract, the content of flavonoid was higher than that of polyphenol and that of the anti-oxidative matter in theethanol extract was higher than that in the hot water extract. The DPPH scavenging effect of P. rhizoma ethanol extract was 75.17±0.68% at 10.0mg/ml while that of hot water extract was 52.33±0.48% at the same concentration, which indicates that of the ethanolextract was higher than that of the hot water extract. It was discovered that the content of SC50 in the hot water extract was 0.939mg/ml,0.497mg/ml for the ethanol extract, and contained 0.062mg/ml of ascorbic acid. This indicates that the P. rhizoma ethanol extract has ahigher anti-oxidation activity than other natural materials although it has slightly lower activity than ascorbic acid. With respect to theSOD-like activity of P. rhizoma, the ethanol extract was 27.32±1.44% in 10.0mg/ml and the hot water extract was 18.84±1.78%, whichmeans that the SOD-like activity of the ethanol extract of P. rhizoma was also higher. As a result of this study, it was discovered that theanti-oxidative activity of the ethanol extract was higher than that of the hot water extract, and the degree of its anti-oxidation is relativelyhigh. Therefore, it is suggested that P. rhizoma extract has high value as a material for functional cosmetics.
