This study is focusing on typicalized character make-up of TV Drama characters. The purpose of this study is to analyze the interconnections of its images and impressiology concretely, and then reflect on an application approach of impressiology. The aim of make-up lies in not only helping actors to visualize their own external qualities, appropriate the quality of a play, but also audience and spectators to be immersed in the concrete fact of i character person. Impressiology will be a data to give the understanding and sympathy of make-up work. I would like to utilize character make-up based on impressiology for creative and effective make-up techniques, and make it a typicalized character. Also I will examine the horizon of a new make-up technique through character development according to the demandes of the times. As a result of this study, we find that expression method of characteristic character generalized representatively is the common quality of impressiologistc image. Also we see that such a impressioiogistic image is useful for the fundamental basis of character expression method.

립스틱의 경우 광택과 광택 지속성은 일반적으로 관찰자의 주관적인 판단에 의해서 측정되곤 하였다. Glossmeter는 네일 에나멜과 같은 메이크업 화장품의 광택을 측정하는데 적용되었다. 그러나 립스틱의 경우에는 항상 일정하게 샘플링하기가 어려워 적용하는데 문제점이 있었다. 또한 광택 지속성은 측정할 수가 없었다. 본 연구에서는 기존의 주관적인 감각테스트에 크게 의존하던 립스틱의 광택 및 광택 지속성의 측정방법을 최적화하여 설정하였다. 도포물질, 크기, 도포회수 등의 변수들을 변화시켜 광택 측정법을 표준화하였다. 그리고 온도와 진동회수를 조절하여 광택 지속성을 측정할 수 있는 최적의 측정방법을 도입하였다. 이러한 방법을 적용하여 측정한 광택값은 주관적인 감각 테스트의 결과와 유사한 값을 나타내었다. 이 방법은 통계적 도구인 6시그마에 의해 재현성과 반복성이 유효하다는 것을 증명하였다.

Generally pigment differs from dye stuff because it cannot be melted in water but also because it is stable physically and chemically. In this study you will discover the function, properties and effects of Micai-TiO$_2$-SiO$_2$pigment as abase material pigment. But until now used Mica of the base material is about 7-l5${\mu}{\textrm}{m}$ with an average diameters of 15${\mu}{\textrm}{m}$. A new characteristic superficial pigment was obtained from covering the TiO$_2$ and SiO$_2$ with the adsorption result of isoelectric point of a Mica flake, TiO$_2$ and SiO$_2$In the composition reaction study of adsorption was done as well as the physical characteristics of the superficial texture of the obtained material. L,a,b of color change as oil was absorbed, optical nature and change of reflection according to direct and diffused reflection. In the composition of Mica slurry the best result obtained was in a solution with pH 2.0 to 2.3. Following this result, we can come to the idea that electrical attraction was done during the change of electrical charge of the Mica and TiO$_2$ deposit. Also this pigment shows a big scale between the direct reflection and diffused reflection light. Using this characteristic in cosmetic, it was obtained a natural but a contrast between light and shadow making possible a sculptured make-up. Color change due to oil adsorption was insignificant which improved the last of make up.

A bacterial strain No. HB-5, which was capable of producing a pretense in the culture conditions, was isolated from the soil . The pretense was purified from cultural filtrate of Bacillus sp. HB-5 by membrane ultrafiltration and DEAE- cellulose chromatography, gel filtration on Sephadex G-100. The molecular weight was estimated to be 60k4a. The optimal pH and temperature for the activity of the purified pretense pH were 11 and 5$0^{\circ}C$ , respectively. The enzyme was stable within a pH range 8-12 and up to 6$0^{\circ}C$ . The enzyme activity was highly inhibited by PMSF at 1mM. The proteolytic actions of pretense and papain on human epidermis keratins which are major protein impurities on the skin, were compared. The bacterial pretense degraded more effectively than papain. Product containing 2% protease exhibited 21% increase on the skin coloration index. These results suggest that cosmetic product containing pretense produced by Bacillus sp. HB-5 could remove the adherent keratin layer and then make a softer skin.

Dry skin is caused mainly by the perturbation of stratum corneum lipids which affected by ageing, change of season, excess use of surfactant and the effect of disease like atopic dermatitis and psoriasis. Intercellular lipid structures in stratum corneum are responsible for the barrier function of mammalian skin. The major lipd classes that can be extracted from stratum corneum are ceramides, cholesterol and fatty acid, which make up approximately 50, 25, 10 percent of the stratum corneum lipid mass, respectively. Small amount of cholesterol sulfate, phospholipids, glycosylceramide and cholesterol esters are also present. Recent studies have shown that application of one or two these lipids to the perturbed skin delays barrier recovery; only equimolar mixtures allow normal recovery. We observed that barrier recovery rate was improved in hairless mouse by topical application of single neutral lipids (ceramide, free fatty acid, cholesterol) and lipid mixtures. Whereas the application of single lipid didn’t allows a significant enhancement comparing with normal barrier repair, the equimolar mixtures of 3 components(including synthetic pseudoceramide PC104) improved barrier repair, as assessed by the transepidermal water loss. At clinical study to the volunteers aged over sixty, skin dryness recuperated by the increase of moisture(capacitance) and the reduction of scaling. Utilization of physiologic lipid mixture containing natural ceramides or synthetic pseudoceramide could lead to new forms of topical therapy for the dryness and dermatoses(e.g., psoriasis, atopic dermatitis and irritant dermatitis).

It has been used that fluorinated compounds could be applied to Make-up products. It is that fluorinated compounds are hydrophobicity, lipophobicity and homophobicity. These fluorinated compounds are reported to form a highly protective and effective film against most aggressive chemical and physical agents. In this study we maed a success to formulate the new type of lipstic using perfluoropolymethylisopropylether with low molecular weight which is long wearing and comfortable to use. This PPIE was adsorbed more than 90% in this experiment and formed the well-balanced gel networks even if the selected PPIE is 100% volatile at room temperature. On the basis of the adsorption of PPIE, we developed the new type lipstick, which was highly-lip feeling and had long wearing and non coloration. And these characteristics were verified by actual consumer test.

나노입자(nanoparticles)는 그 크기가 피부를 구성하는 세포보다 작다. 따라서 세포막을 통과하고 약물 또는 유전자를 전달하는 매개체로서의 역할에 매우 적합하며 특정 성분을 피부 속에 전달할 수도 있다. 본 연구에서는 쑥으로부터 나노입자를 추출하여 dynamic light scattering (DLS)를 통해 100 nm 전후 크기의 입자를 얻었음을 확인하였고, MTT assay를 통하여 섬유아세포에서 cell viability를 농도 의존적으로 증진시키는 결과를 얻었다. 또한, quantitative real time PCR 분석법을 통해서 COL1A1 mRNA 발현량을 증가시키고 IL-6 mRNA 발현량은 감소시킴을 확인하였다. 세포실험뿐 아니라 화장품 제형에서도 적용 가능하며, 안정함을 확인하였다. 최근 화장품 산업 동향에서 화학 성분을 배제하고 식물 유래 성분 수요가 지속적으로 높아지고 있는 반면, 식물에서 유래된 나노입자의 응용분야를 제시하는 연구 결과가 거의 없다는 한계가 있다. 따라서 현시점에서의 화장품 산업의 한계점을 극복하고자 본 연구를 통해 얻은 결과를 견주어 쑥으로부터 유래된 나노입자를 고기능성 화장품 소재로서 제시하고자 한다.

The new stick make-up product was studied by using a gel, which is a viscous complex formed with clay minerals, vitamins A and E and fluorinated liquid polymer with a 1500 molecular weight. The gel cannot be obtained with any random combination of clay minerals and the ingredients described above. It takes the sequential manufacturing method as follows to get this kind of gel. Firstly, clay minerals and liquid polymers have to be pre-mixed in order to saturate the liquid polymers with the clay minerals. Then the on-processed gel has to be finely crystallized. The clay minerals, which are the core elements for this gel, were used as a function of Binder & Buffer and liquid polymer was mixed together for the deterioration of the surface tension of each component and to form a functional film in the gel. This liquid polymer was combined with clay minerals because it is not miscible with most oils and solvents. Waxes have a function of keeping a solid status in the stick. We reduced the usage of waxes by putting clay minerals as buffer in the proportion of 0.5:1 with oil phase. Ceramide takes care of the skin when used regularly and maintains the skin's moisture. Vitamins A and E contribute to preventing skin aging by the activation of skin cells. We could get the stable viscous gel, which has about 80% oil phase using clay minerals and liquid polymer. The crystalline structures of gel were surface-chemically-analyzed using SEM and Image Analyzer and were thermodynamically analyzed using DSC. Surface tension test and softness were done by Rheometer. In the end, these characteristics were verified by consumer panel tests in Seoul, Daegeon and Pusan in Korea and Hokkaido, Osaka and Miyazaki in Japan with correlation to the climate.
