Ozone(O$_3$), one of best-known toxic air pollutant, act as a strong oxidant. It is possible that skins exposed to the air can be easily damaged by such oxidative air pollutants. Therefore, in the present study, anti-oxidative effects of natural product. on $O_2$ㆍ and ㆍOH were investigated by EPR. Ozone caused protein damage and lipid oxidation, in HaCaT and B16F10 leading ultimately to programmed cell death. It also reduced the level of antioxidant molecules including ascorbic acid and tocopherol in stratum comeum. However, antioxidants originated from natural products could protect skin from these products could protect skin from these oxidative damages. We concluded that eight natural extracts including Rosa davurica, Ligularia sibrica, Green tea acted as strong antioxidants against ozone.

Trimethylglycine, commonly named betaine, is the most simple amphoteric molecule. It is completely vegetal (1,2), as it is produced in the sugar industry by industrial chromatography of molasses. While abundantly used in foods and diet supplements, many interesting applications in cosmetics have recently been investigated, like its capability to increase the volume and stability of foams in surfactant solutions. For its special chemical structure (it is the internal salt of a weak acid and a strong alkali) trimethylglycine is a solvent and buffering agent for strong acids and Lewis' acids. It allows to improve the efficiency of $\alpha$- and $\beta$-hydroxy acids in increasing the physiological rate of epidermal cell renewal, while keeping a low skin-irritation level. In oral care cosmetics, it acts as a mucous membrane protectant (3). For its special water co-ordination capability, its solubilising power, polymer swelling capability, after-feel improvement in hair products, skin moisturization and elasticity enhancing properties, trimethylglycine provides unusual characteristics to many products intended for skin maintenance (4).(omitted)

립 메이크업 제품은 음식물과 함께 체내로 유입되므로 안전성에 대한 필요성이 다른 화장품보다 크다. 또한 합성 안료인 타르계 색소에 대한 안전성 문제가 지속적으로 부각되고 있는 상황에서 천연색소에 대한 요구가 점점 증가되고 있으며, 많은 종류의 천연 색소가 개발되고 있다. 하지만 립메이크업 제품에 합성색소 대신 천연색소를 이용하기에는 여러 가지 문제점이 있다. 대부분 천연 색소는 안토시아닌 계통의 친수성 물질로 구성되어 있지만, 기존의 입술 화장료는 오일과 왁스로 이루어진 무수상태의 유분산 제형이 대부분이기 때문이다. 따라서 립메이크업 제품은 상기에서 설명한 바와 같인 무수제형이기 때문에 수용성인 천연색소를 사용할 경우에 색상발현도가 낮고 불안정하여 제형에서 색소가 분리되기 쉽다. 또한 천연색소는 pH, 열 및 일광 등에 의해 쉽게 변하는 단점이 있는데, 무수제형에서는 이에 대한 조절이 쉽지 않아 안정도에 문제점을 가지고 있다. 따라서 본 연구에서는 천연색소를 사용하여 인체에 안전하면서 색상 표현력이 우수한 립메이크업 조성물에 대하여 연구를 수행하였고, 천연색소를 유중폴리올 에멀젼에 포집하여 색소의 안정도를 확보하였으며, 수분증발 시 생기는 건조함이 없는 우수한 보습력을 갖는 립메이크업 제품을 제조하였다.

The purpose of this study was to investigate how brand identity expressional elements in cosmetic road shops' facades would affect the brand awareness of consumers while extracting those brand identity expressional elements observed in the facades of the cosmetic road shops. In order to achieve the research goal, the study used Q methodology, a method to measure subjectivity. The results have been summarized as follows. (1) The elements to express the brand identity found in the facades of the cosmetic road shops were observed to be two-dimensional expressional elements, and they should include a symbol, a logo, a signboard, materials to express an image (products, models) and a brand color. As for the three-dimensional expressional elements, they were a building (form, materials, pattern), decorations (lean-to roof, canopy, sculptures, lighting, screen) and a display window (focusing on products, visuality or the inside of a shop). (2) The findings of the analyses on the brand awareness using Q methodology have been presented as follows. (1) When multiple identity expressional elements which would be associated with each other are used, the brand awareness gets increased relatively efficiently. (2) In case of men, they would perceive a brand more easily through those formative expressional elements such as a form of a building. (3) In case of women, they would perceive a brand more conveniently through those visual expressional elements such as a brand color. (3) In conclusion, the study figured out that, among the brand identity expressional elements, the one which would influence the brand awareness most would be (1) the brand color, followed by (2) the building-form, (3) the lean-to roof, (4) the display window and (5) the logo. Based upon what has been learned so far, the study confirmed that when it comes to securing the brand awareness in the market, cosmetic companies should, first, realize how important it is to make good use of the two-dimensional (visual) expressional element, the brand color, and the three-dimensional expressional element, the form of the building, together before they even try to design facades of their shops on the streets.

이 논문은 우리나라의 광고에 큰 비중을 차지하고 있는 화장품 광고에서 광고모델 속성이 여성 소비자의 화장품 구매에 미치는 영향에 대한 실증적인 연구이다. 그 결과 소비자들은 광고 모델 속성에 대해서 신체적 매력 보다 전문성과 진실성이 있어야 한다고 응답하였다. 광고 모델이 좋아서 화장품을 구입한 경우, 호감과 신체적 매력은 매우 긍정적인 반응으로 나타났고, 전문성과 진실성은 부정적인 반응으로 나타났다. 여성 소비자들은 현재 광고되고 있는 화장품 광고 모델들에 대해서 관심은 있으나 모델들의 신뢰도가 부족하여 구매에 영향을 미치지 못하고 있다. 우리나라의 화장품 광고 모텔은 대부분 유명 연예인이기 때문에 신체적 매력, 호감, 친밀감은 높은 긍정적 반응을 보이고 있으나, 전문성, 진실성, 유사성은 매우 부정적인 반응을 나타내고 있다. 그러므로 화장품 광고 모델 유형에 따른 모델 속성을 실증적으로 연구한다는 것이 다소 무리였다고 생각된다. 화장품은 감성적으로 선택되며 자기 관여도가 높은 제품이므로 광고하는 제품에 대한 지식·경험·능력을 가진 전문성이 연상되는 모델의 선정이 바람직하다고 본다. 그리고, 제품에 대한 어떤 편견도 없이 순수하게, 객관적으로 의견을 제시할 수 있는 진실성과 제품·소비자와 이미지가 일치하는 광고모델이 적합하다고 본다.

For empirical study a questionnaire developed by researchers was distributed to 456 of university women in Chonbuk province from Aug. 26 to Sep. 17 1998. Frequencies and percentages were claculated. And factor analysis cluster analysis and $\chi$2-test were used. The results were as follows: 1. University women were clustered into 5 types of sound and self pursuit type realistic and fashion pursuit type external and liberal type delightful and enjoying type and passive and stagnate type according to their life styles. 2. Sound and self pursuit type was characterized by the faithfulness to school and home life and economical lining. They got cosmetics information through direct experiences by use of samples put on full make-ups to protect their skin and selected refill cosmetic products to save money. 3. Realistic and fashion pursuit type were sensitive to fashion and had a strong desire for material achievement. They put on full make-ups exchange unsatisfactory cosmetics at the store where they bought and had a lot of imported cosmetics experiences. 4. External and liberal type showed little concern with saving and had progressive thinking. They bought cosmetics at the department store got informations from market-oriented information sources. perferred shopping at department stores considerred price most important when selecting cosmetics exchanged unsatisfactory cosmetics at the store they bought when they were not satisfied with the flavor or skin troule. 5. Delightful and enjoying type showed the least faithfulness to their home and school life. They put on partial make-ups for the correction of facial defects or etiquette. 6. Passive and stagnate type enjoyed home life but were passive in real life and open-mindness They got cosmetics information from marketer-oriented information sources bought cosmetics at discount stores considered price most important when selecting cosmetics put on basic or at least mke-ups to protect their skin had the least experience in the imported cosmetics and refill products.

연구에서는 수염에 대한 면도력을 향상시킬 수 있는 화장료 제형 개발을 위하여 대면용 화장료에서 사용가능한 우레아 및 여러 항산화제의 수염 강도 약화 효과를 연구하였다. 실제 모발 강도 약화 효과는 우레아 농도에 의존적인 성향을 보였으며, 모발 면적 증가율 역시 농도에 의존적인 것으로 나타나 우레아 농도에 따라 모발의 수화 정도가 달라지며 이것이 강도 약화에 영향을 주는 것을 확인할 수 있었다. 항산화제는 종류에 따라 소량으로도 뛰어난 강도 감소 효과를 보이며, 이는 모발에 다량 존재하는 시스틴 결합을 환원시키기 때문으로 해석된다. 마지막으로 대면용으로서의 적합성 판단을 위해 우레아 및 항산화제의 in vitro 안전성 테스트를 진행하였다. 안전성 테스트 결과 우레아는 대면용으로 사용하기 적합한 정도로 나타났으며, 항산화제 중에서는 글루타치온이 적합한 것으로 나타났다. 위 결과들을 통해 피부 자극이 적고 모발 강도 약화 효과가 뛰어나 면도용 제품에 적용하기 적합한 원료는 우레아 및 글루타치온임을 알 수 있었다.

As the consumer market in the cosmetic, vehicle manufacturing and aerospace industries grows, the demand for manufacturing industries using on injection mold technology. Also, such manufacturing technology of metal machining is expensive, and the shape is limited. Cosmetic cushion fact products are divided into outer relevant to the exterior of the product and inner containers containing the actual contents. In the case of the inner container, it needs to be combined with the upper and lower cases. As environmental regulations are strengthened internationally, the use of a large number of component parts can result in significant losses in recycling and economics. Therefore, this study aims to perform injection molding analysis through injection molding simulation to develop a cushion fact container that can be recycled through the unification of products and materials using polypropylene to cope with environmental regulations. In the case of injection molding conditions, Injection Time(sec): 4.5, Cooling Time(sec): 13, Resin Temperature($^{\circ}C$): 240, and Pressure(MPa): 30 were determined. The results of injection molding simulation according to the two design methods were compared with the sync mark which shows the problem of filling and injection molding.
