목 적 : 국내에서 유통되는 미용칼라 콘택트렌즈를 무작위로 수집하여 렌즈표면의 상태, 염료의 용출 여부 및 중심부와 주변부의 산소투과율을 측정하여 미용칼라 콘택트렌즈의 물리 화학적 특성을 평가하므로 임상에서 활용할 수 있는 정보를 얻고자 한다. 대상과 방법 : 굴절력이 0.00D이며 중심부가 투명하고 주변부가 착색된 미용 칼라콘택트 렌즈 24종을 무작위로 수집하여 식약청 기준에 의한 용출물시험과 ISO 9913-1에 의한 산소 투과율 측정 및 주사전자현미경에 의한 표면 거칠기를 관찰하였다. 결 과 : 용출물시험에서 5종의 렌즈가 과망간산칼륨 환원성물질에 대한 기준을 초과한 것 으로 나타났다. 산소투과율은 24종 가운데 6종은 중심부보다 주변부에서 낮았고, 중심부 산 소투과율은 3종만이 낮에 각막부종을 유발시키지 않을 조건을 충족시켰고, 주변부의 평균 산 소투과율은 모든 렌즈에서 기준을 충족하지 못했다. 렌즈표면 상태를 관찰한 결과 제조회사 별 착색방법이 서로 달랐다. 착색방법은 전사착색법, 전면착색법, 후면착색법 및 샌드위치착 색법 등이 사용된 것으로 확인되었고, 표면 거칠기는 수 ㎛ 이하로 판단되었다. 결 론 : 미용 칼라 콘택트렌즈를 착용할 때 낮은 산소투과율로 인한 부작용을 방지하기 위해 렌즈 제조공법과 렌즈 재질의 개선, 임상에서 미용 칼라 콘택트렌즈를 처방하고 판매할 때 착용자에게 렌즈의 관리방법과 사용방법을 정확하게 전달하기 위한 교육이 필요하며 이에 본 연구결과가 기초자료로 활용될 수 있을 것으로 사료된다. 또한 미용 칼라 콘택트렌즈를 착용할 때 용출물과 표면 거칠기로 인해 발생할 수 있는 부작용에 관한 추후 연구가 필요하 다고 사료된다.

The work of hairdressers includes washing, coloring, bleaching, permanent waving, conditioning, and cutting scalp hair. Hairdressers are subjected to a number of physical and toxicological hazards. The toxicological hazards are those resulting from exposure to a wide range of chemicals and from chemicals are usually classified active processes. In this study, twenty beauty shops were selected to assess the exposure to indoor air pollutants such as VOCs and particulate matter (PM10) during one month from September 1 to September 30, 2003. Indoor air quality of beauty shops might be worse by vehicle emissions because the beauty shops were generally located near roadway. Personal exposures to VOCs and PM10 were related to indoor concentrations of beauty shops, respectively. According to questionnaire, hairdressers responded sore throat, eye irritation, and nervousness as health effect symptoms. Conclusively, users as well as workers in beauty shop might be highly exposed to air pollutants from indoor sources and outdoor sources. Therefore, proper methods should be prepared to improve the indoor air quality in beauty shop.

반응표면분석법으로 식품위생관련 세균의 불활성화를 위한 가열처리 조건(온도. 시간)을 최적화하다. 균주의 생육에 대한 반응표면 회귀식의 R^2은 P.aeruginosa가 0.9155(P<0.05). E. coli는 0.8997(P<0.05).S. typhinurium은 0.9690(P<0.01), E. aerogenes는 0.9393(P<0.05) 및 V. parahaemolyticus는 0.7905로 나타났다 가열처리 온도 및 시간에 따라 주의 생육에 유의적인 영향을 미치는 것으로 나타났으며. 생육억제에는 반응온도가 가장 큰 상관관계가 있음을 보여주었다. 각각의 가열처리 조건에 따른 균주의 불활성화를 종합하여 superimposed contour map을 작성한 결과. 55.62∼60℃에서 19.25∼30분간의 처리가 균주으 불활성화 최적조건이었다. 본 연구는 피부미용전공과 비전공여대생의 모발영양지식을 파악하고 모발영양에 관한 과목을 수강한 학생들과 수강하지 않은 대상자들간의 모발상태. 모발행등 등을 연구하고자 청주에 있는 피부미용과 여대생 146명과 비전공여대생 145명을 선정하여 설문지를 통해 분석하였다. 본 연구에서 얻어진 결과는 다음과 같다. 모발영양지식은 전공여대생이 비전공여대생에 비해 훨씬 높았고. 모발의 진단을 받아본 경험도 전공대상자가 높았다. 그러나 모발상태. 손상원인 모발에 관한 걱정은 두 그룹 모두 비슷한 양상을 보였다. 모발관리도 전공대상자가 비전공대상자보다 많이 하고 있었고, 모발손질 횟수도 전공대상자가 높은 비율로 나타났다 미용실 출입횟수는 2∼3달에 한번이 가장 높았고, 그룹간에 차이는 없었다. 1회 머리손질 비용도 전공대상자가 비전공대상자에 비해 높은 경향이었고. 샴푸의 선택기준은 두 그룹 모두 샴푸의 질과 본인 모발의 상태를 우선적으로 고려하여 선택하였다. 결론적으로 피부미용전공 여대생은 모발영양관 모발관리학 등에 관한 수업을 받았기 때문에. 모발영양 지식이 많아 모발행동이 더 바람직하였고 도발상태를 양호하게 유지하였다. 그러므로 모발에 관한 교육 건강한 모발을 유지하는데 기여한 것으로 나타나. 적절한 모발교육 프로그램을 개발하여 비전공여대생들에게도 모발교육을 실시하는 것이 바람직하다고 사료된다.

The ultraviolet blocking agents used to skincare are largely classified ultraviolet scattering agent and ultraviolet absorbent agents. There are UVC, UVB, and UBA in ultraviolet ray(UV) showing shorter wavelength than visible light. Both visible light and UVA give rise to 1st dark-skinned phenomena. On exposure of the skin to UV, phenomena of skin variation are termed sunburn or suntan. There are chronic and acute adverse reactions in skin response to UV. The latter is caused by UVB, which has mainly effects on the skin. But lately due to destruction of ozone layer, UVA has more serious irritation on the skin than UVB. In this paper spectrometric properties of UV absorbent agents such as PABA, octyl-PABA, Urocanic acid, and 2-hydroxy-4-methoxy benzophenone in vitro have been investigate. As results, it was found that the three fomer were more suitable than the last. UV scattering measurements on the sample used inorganic pigments showed that pigments containing titanium dioxide had a better scattering effects than the inorganic pigments such as Fe2O3, Al2O3, etc.

The purpose of this study was to investigate the changes in body temperature of canine via their hair lengths before and after grooming. A total of 120 companion canines were used in this study for a total of 6 weeks, and 20 dogs each week consisted of both 10 poodles and 10 malteses (five females and males). For accurate temperature measurement, the anal depth was measured at approximately 1.5 cm. Temperature before and after grooming was measured at 10 am and after more than three hours, respectively. There was statistical significance (p<0.05) in body temperature changes for male poodles at 1, 2, and 3 weeks and for female poodles at 1, 3, 4, and 5 weeks, and the total period showed a statistical difference for both male and female poodles (p<0.05). In addition, male and female malteses had an effect (p<0.05) on changes in body temperature at 1 and 6 weeks and only at 4 weeks, respectively. For total period, there was a statistical difference in male and female poodles (p<0.05). Moreover, when the temperature changes of females were compared, there was no remarkable difference. In conclusion, the body temperatures of both male and female dogs according to the length of their hair were lower after grooming than before grooming. The measurement of body temperature three hours after grooming, which could reduce stress or other factors, is judged to be able to help customers who are worried about clipping.

The purpose of this study was to investigate the effects of desensitization and flooding on the behavior of dogs during grooming, focusing on their response to the sound and skin stimulation while using a clipper. A total of 20 adult dogs over two years of age with complete personality formation were included in the study. Ten dogs, of which three were Bichons (average weight 5 kg), four were Poodles (average weight 5 kg), and three were Malteses (average weight 4 kg), were subjected to the desensitization process. The remaining 10 adult dogs were subjected to the flooding experiment, and were of the same breed and average weight as the adult dogs used in the desensitization process. The desensitization and the flooding were performed three times a day (approximately 1 min per session) for 10 days. For desensitization, statistical significance was observed only on the fifth day, when compared by breed (p<0.05). Overall, when compared by measurement day, the results of desensitization for Bichon, Poodle and Maltese dogs were statistically significant (p<0.05). The results for the Bichon, Poodle, and Maltese dogs that were subjected to flooding were found to be statistically significant (p<0.05). There was a significant difference in the results of the flooding on the second and ninth days (p<0.05); however, flooding had no effect on the other days (p>0.05). Desensitization using the clipper, a beauty tool, was faster than flooding in achieving stabilization. In conclusion, desensitization and flooding showed positive results on the stress relief and emotions of dogs during grooming, with respect to cosmetic fear response.

In this study, beauty food activities were determined for extracts of Saurus chinensis as functional beauty food. Tyrosinase inhibitory effect was increased as more 4 folds by ultra-fine grind technology than normal grind technology in ethanol extracts from Saurus chinensis. A ultra-fine ground technology was used to increase the extraction yield for bioactive compounds from medicinal plants. Tyrosinase inhibitory activity, which is related to skin-whitening, was confirmed to be 100% for ethanol extracts at 1,000 ppm of phenolics. Anti-wrinkle activity was determined showing 30% of inhibition effect at above 1,000 ppm phenolic concentration. The elastase inhibitory activity of water and ethanol extracts from ultra-fine ground Saurus chinensis showed higher inhibition activity than compared to extracts from normal ground Saurus chinensis. Astringent activity in ethanol extracts was determined showing over 70% at 250 ppm of phenolics. Based on these results, Saurus chinensis extracts can be used as a functional beauty food and cosmetic with whitening, anti-wrinkle and pore contraction effects.

The purpose of this study is to examine the health of beauty salon workers through the utilization of questionnaires concerning the extent of exposure to organic solvents found in the air of some beauty salons and any resultant symptoms in employees. The subjects were 36 employees from 10 beauty salons who agreed to participate in this study. The degree of exposure to organic solvents in the air of beauty salons was measured from September 1, 2008 to September 30, 2008. A survey of symptoms that occurred due to exposure to these solvents was also performed. The results were as follows: questionnaires were collected and analyzed from a total of 36 subjects. Of these, 28(77.8%) were female and 8(22.2%) were male. The mean age was 29.08. The mean working period was 7.13 years. Sixteen subjects attended programs at universities while 11 went to beauty schools for vocational education. When testing the concentration of organic solvents in the air of beauty salons, the highest value found was Isopropyl alcohol 511.85 ppb followed by butyl acetate, toluene, acetone, xylene, ethyl benzene, styrene, and chlorobenzene. A logistic regression analysis was performed as follows: the point of each factor was the dependent variable while sex, age, drinking, smoking, educational level, work experience, hairdresser’s license, and organic solvents were the independent variables. Statistically significant difference (p<0.05) was shown in the hairdresser’s license among Factor 1 and in Xylene among Factor 2; however, difference was not shown in the other variables.
