세리신은 누에고치에서 추출한 단백질로 많은 건강상의 이점을 가지고 있다. 본 연구는 화장품 소재로서 누에고치에서 유래된 세리신 표준품의 항주름 활성 및 항염증 활성을 평가하기 위해 수행되었다. 세리신의 항산화 효과는 DPPH 및 ABTS 측정법에 의해 측정되었다. 또한 대식세포인 Raw 264.7 cell에서의 세포 생존율을 확인하였으며, lipoplyscaccharide를 이용하여 유도된 염증반응을 이용하여 세리신의 항염증 효과를 조사하였다. 그 결과 세리신은 DPPH, ABTS에서 항산화 활성을 보였으며 세포 독성을 가지지 않은 1,000 ㎍/mL의 농도에서 NO를 억제하였다. 종합하여 세리신은 항산화 활성을 가지며 항노화 및 항염증 화장품의 우수한 소재가 될 수 있음을 보여준다.

나노입자의 응용은 1970년대부터 발전되어 왔다. 금속 나노입자에 빛을 조사하면 나노입자 표면에서 플라즈몬 공명(SPR, surface plasmon resonance)을 일으킨다. SPR 효과는 금속표면에 입사한 빛에너지에 의해 전자가 여기하며 공명을 일으켜 진동을 발생시키는 현상을 말한다. 여기 된 전자들이 금속원자들과 충돌을 일으키며 열에너지로 전환될 수 있는데 이를 금속의 광열효과(photothermal effect)라고 한다. 우리는 광열 효과를 이용하여 온열 화장품의 개발 가능성을 제시하고자 한다. 온열 화장품의 개발을 위해 생체 독성이 적은 금 나노입자를 선택하여 광열 효과에 있어서의 세포 생체적합성과 열효율을 살펴보았다. 금 나노입자의 합성 상태는 금 나노입자가 갖는 독특한 흡광 스펙트럼으로 확인하였으며, 금 나노입자의 농도는 원자 흡광분석기로 측정하였다. 세포의 독성평가는 MTT assay와 이중 염색법을 사용하였으며, 금 나노입자의 광열 효과는 제논 램프를 광원으로 하여 금 나노입자의 농도의 증가에 따른 광열 효과증대를 적외선-열화상 카메라로 확인하였다. 금 나노입자의 광열 효과를 온열 화장품에 적용한다면 한대 지방의 기후, 또는 겨울철에 태양 에너지를 열에너지로 전환시켜 피부에 손실된 열을 공급, 피부온도 유지에 도움이 되고 피부건강에 긍정적 효과를 주리라 사료된다.

Purpose - The purpose of this study is to investigate economical ventilation effectiveness to reduce hazardous materials exposure and damage of workers by analyzing exposure amount of noxious substances under various ventilation conditions of nail salon for indoor environments. Research design, data, and methodology - This study was carried out with cooperation of Nail shop located in SeongNam city to involve an analysis of the environmental impact indoor air quality, pollutant exposure and economical cost-effectiveness in the nail workplace. The hazardous substances were PM-10(Particulate Matter-10㎛), VOCs(Volatile Organic Compounds) and Formaldehyde, which are the major materials of nail workplace. Results - PM-10 is reduced by about 60% with air cleaner, forced artificial ventilation by 32%, and natural ventilation by about 12%. TVOCs and Formaldehyde showed similar efficiency (80~100%) after natural ventilation and ventilation after 60 minutes. The removal efficiencies of VOCs and formaldehyde were similar to those of natural ventilation and mechanical ventilation system. However, in case of dust, natural ventilation was reduced by artificial ventilation system due to inflow of external dust during natural ventilation. Conclusions - If the pollution degree of outdoor air is not high, air volume is high, and natural ventilation is performed when the air conditioning and heating system is not operated. Even at the end of the work, it keeps operating for 60 minutes to remove the pollutants generated. Results of this analysis demonstrated that the worker environment can be improved by adopting institutional legislation and guidelines for ventilation.

Functional cosmetics are intensively investigated for the effectiveness of skin whitening, anti-aging and slimming. For enhancing the effectiveness, active ingredients should be delivered into the cell in the dermis. The amounts of penetration of caffeine and $Arbutin^{(R)}$ were tested, in vitro, using Franz diffusion cell. Oil-in-water emulsions were used for the vehicles of the transport. For the measuring the amounts of active ingredients delivered into the dermal skin, tape stripping was done after finishing the penetration experiments. The amounts of delivered caffeine were $8.45{\pm}$ 1.26ug/ml before tape stripping and $3.45{\pm}$ 1.80ug/ml after tape stripping, however, the amounts of delivered $Arbutin^{(R)}$ was quite small to detect. From now on, proper vehicles are considered for enhancing the delivery of $Arbutin^{(R)}$ Hairless mouse skin was compared with pig skin as a transdermal delivery membrane. The aspects of delivery were similar, but the amount of delivered ingredients using pig skin was larger than that of using hairless mouse skin. Therefore, the pig skin would be considered as a membrane for drug delivery experiments.

A new colloidal silver (Ag) system is present in which a fine colloidal Ag is in situ deposited onto functionalized porous poly (ethylene glycol dimethacrylate) (poly (EGDMA)) microspheres. The effectiveness of Ag deposition was investigated considering the surface characteristics of poly (EGDMA) microspheres. The result reported in this study illustrates that the control of surface area and surface functionality (in this study, a hydroxyl group) of poly (EGDMA) microspheres is an important factor that determines practically the degree of deposition of colloidal Ag. The x-ray analysis showed that Ag nanoparticles were dispersed evenly inner and outer surfaces and had a face center cubic (fee) phase. In the preservative efficacy test, the Ag-containing poly (EGDMA) microspheres had a powerful anti-bacterial activity, showing a high potential for a new preservative in cosmetic industry.

The purpose of this research is to provide the basic data for the development of make-up color application system, based of Korean's skin tone and the preference in make-up color to enhance the effectiveness of the education of beauty in universities. The research was conducted by the previous studies, the analyses of sale's rate of hue-cosmetics, the analytic experiment of color of cosmetics by using Spectrum Color Analyzer and other experimental researches. This research, based on the results of three preliminary researches, shows the result of evaluation from perceivers which has been come out from the experiment of having one model in her twenties being changed with twenty-two different conditions of make-up. Here follows the result of the research. Firstly, there was difference on perceiving images in terms of the gender of perceivers and especially male-group tend to have clearly perceived the gap between elegance-greyish purple, orange-natural, red-classic on monochrome make-up and contrast make-up. Secondly, in terms of lip-colors, salmon pink and pink was regarded positively to both female and male subjects and to male subjects, greyish purple was thought to be better on darker skin-tone and to female subjects, better on lighter skin-tone. Thirdly, on image make-up, romantic gives intelligent image regardless of skin-tone and gender, especially gives more positive looks to male subjects. Natural and classic elements were perceived more positively on darker skin-tone and had bigger perceiving gap in female subjects. Fourthly, in preference rate, male subjects normally preferred the look with make-up than female subjects did and salmon pink and pink lip color was preferred on the darker skin-tone.

The purpose of this study was to examine the differences of the information searches and purchasing behavior Korean men in their 20s and 30s, focusing on cosmetic involvement. Research methods consisted of qualitative and quantitative approaches. For the qualitative approach, in-depth interviews and participant observations were conducted to investigate male customers' cosmetic characteristics in information searches and purchasing behavior. Then, the study conducted a quantitative study methodology based on the questionnaires from the in-depth interviews, participant observations, and literature review. The study surveyed 340 Korean men in their 20s and 30s. The cosmetic involvement of the target group was classified into the amusing high-involvement group, the rational low-involvement group, and the obligatory high-involvement group. The results from this study indicated that the groups of male customers classified by cosmetic involvement showed statistically significant differences in terms of information searches and purchasing behaviors. Especially, the obligatory high-involvement group generally displayed high-involvement traits likewise the amusing high-involvement, was more similar to the rational low-involvement group regarding cost effectiveness than the obligatory high-involvement group. Moreover, the classifications of men generally had different characteristics of cosmetic purchasing behavior and information searches than women. This study has a distinctive significance compared with other studies in discovering differences of cosmetic purchasing behaviors of Korean men in their 20s and 30s' cosmetic involvement groups classified using qualitative and quantitative approaches.

본 논문에서는 온라인 고객 리뷰를 활용하여 건강 보조제, 화장품 등 현재의 상태를 개선하기 위해 사용되는 제품을 대상으로 그 효과를 알아보기 위한 제품 효과 분석 기법을 제시하였다. 제안하는 제품 효과 분석 기법은 블로그 포스팅에 존재하는 광고를 자동 제거하고, 효과 분석을 위한 증상, 효과, 증가, 및 감소로 이루어진 단어 사전을 구축하며, 제안하는 알고리즘을 통해 제품의 효과를 측정한다. 제품 효과 분석 기법을 검증하기 위해 정답 레이블이 존재하는 네이버 쇼핑 리뷰 데이터셋을 대상으로 성능평가를 실시하였으며, 전통적인 긍부정 사전과 RNN 모델과 성능을 비교하였다. 실험 결과, 본 논문에서 제안하는 효과 분석 기법이 다른 두가지 방법보다 정확도가 뛰어남을 보여주었다. 또한, 아토피 피부염, 여드름 치료제에 제안하는 기법을 적용하여 소셜 미디어에 나타난 효과적인 치료법을 소개하였다. 본 논문에서 제시한 알고리즘은 블로그를 포함한 여러 매체의 리뷰로부터 제품의 효과를 점수화할 수 있으므로 다양한 제품군과 소셜 미디어에 적용될 수 있을 것으로 보인다.
