최근 제품개발의 동향은 소비자 각각의 특성에 맞춘 "맞춤 컨셉"을 가진 제품 개발이 활발히 진행되고 있다는 점이다. 특히 그 어떤 제품보다도 소비자가 사용 시 느끼는 관능특성과 그에 대한 만족도가 중요시되는 화장품의 경우는 더욱 그러하다. 따라서 본 연구에서는 이미 대중화 된 베이스 메이크업과 립 메이크업 외에 최근 소비자들의 관심이 증가하고 있는 마스카라를 대상으로 한국 여성들에게 맞는 마스카라의 특성을 파악하고, 그 관능특성을 분석하여 한국 여성들의 니즈에 맞는 제품을 제시하는 것을 목적으로 하였다. 한국 여성들의 눈과 속눈썹 모양에 대한 조사에서는 클러스터 분석을 통해 대표적인 눈과 눈썹의 형태를 4가지 그룹으로 나누고, 각 그룹의 특성에 맞는 마스카라의 기능을 제안하였다. 그런 후, 전문패널을 대상으로 여러 기능의 마스카라를 이용해 마스카라의 관능특성을 평가하여 상기의 조사에서 나온 4가지 그룹에 대한 각각의 적합한 사용감을 제안하였다. 본 결과는 차후 소비자 특성에 맞는 마스카라 제품 개발 시 활용될 것이다.

The relationship between texture and rheological properties of mascara(oil-in-water emulsion) was analyzed in this study. The final mascara product and gelling agents(2.0 wt%) used therein, such as hydroxyethylcellulose(HC), carboxymethylcellulose(CMC), hectorite, sodium magnesium silicate (SMS), hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer(HS), and polyacrylate 13/polyisobutene/polysorbate 20 (PPP), were measured for rheological properties. As a result, HS and PPP showed the highest adhesiveness which were related to the volumizing effect of mascara. The viscosities of HC, SMS, and HS were measured at the stress range of $1{\sim}1,000s^{-1}$. SMS, with the lowest storage modulus range of $100{\sim}1,000s^{-1}$, affected the mascara in terms of smooth texture. The results of this study suggest that the rheology of gelling agents used influences the final texture of the mascara.

Purpose : To evaluate the degree of the artifact which is caused by the mascara and the eye shadow when acquiring MR images and compare the difference of the image distortion according to the change of various pulse sequence. Material and Method : The popular domestic mascara and eye shadow products were selected from three different companies respectively and divided into two groups mascara (M1, M2, M3 ), eye shadow (E1, E2, E3). Self-designed quadrature type saddle coil which has 4 cm inside diameter, 8 cm length and which is for both Tx and Rx was used. MR image was acquired respectively after applying the mascara to the tape from study 1, the eye shadow to the tape from study 2 and adding the eye shadow to the mascara from study 3. The FSE(fast spin echo), the SE(spin echo), the GE(gradient echo) were used as pulse sequences. The degree of the image distortion which was measured from each sequence was analyzed in quality and quantity. Result : The mascara and the eye shadow caused the artifacts to the MR images partially and induced the image distortion. There was a little difference in terms of the degree of artifact according to the change of pulse sequence. From the study 3 in which the eye shadow was applied to the mascara, on the axial plane image, the width of artifact was 16.73 mm in the GE pulse sequence, 6.64 mm in the SE pulse sequence, and 6.19 mm in the FSE pulse sequence. The degree of the artifact appeared highly in order of the GE, the SE and the FSE. On the sagittal plane image, the length of artifact was 22.84 mm in the GE, 17.81 mm in the SE and it appeared highly with the SE and the FSE technique order. Conclusion : When examining the eyeball and the brain of a woman with the mascara and the eye shadow, we have to consider that the artifact caused by them can have an effect on the image diagnosis. We concluded that it is more suitable for a brain and a eyeball T2 emphasizing image to use the FSE technique than the GE technique.

Carbon black have not been used as pigment material in cosmetic because of very low density and dispersity, but carbon black have applicable character as black pigment because of non-toxic, stable physico-chemical property, and black colority. In this study, mesoporous silica samples were synthesized by sol-gel reaction using surfactants-template method; TEOS (tetraethoxysilane) - a) PEO/lecithin, b) PEO/polyethylene glycol, c) lecithin/polyethylene glycol in ethanol/water solution. Synthesized organic-inorganic hybrid - silica were heat-treated in N2 condition at 500$^{\circ}C$. Mesoporous silica with black carbon in pore have the effective density and show the good dispersity in both hydrophilic and hydrophobic solvent. Properties of the samples were measured; specific surface area (750㎡/g) and pore size (4-6nm) using BET, pore structure (cylindrical type) using XRD, morphology (spherical powder with 0.1-0.5$\mu\textrm{m}$ partical size) of the samples using SEM. Carbon-silica black color applied to mascara, it shows a dark black colority and good dispersity as compared with the general black color titania pigment. Moreover, it is possible to control the density of black color pigment because it is possible to control pore volume and particle size of mesoporous silica properly. It show the good volume effects in mascara. That is why possible to apply all kinds of cosmetic products.

This study investigated differences in perception by 240 males in their teens, 20s, 30s, and 40s residing in Seoul, Incheon, and Gwangju about seven items for male makeup, and analyzed makeup items preferred by men, perception about male makeup users, and relationship between success and appearance, thereby providing basic materials to activate the beauty market for males and developing goods for male users. The result was that most males thought the influence of their appearance on their social success was great and in particular, 23.3% of respondents thought that their appearance affected their success by 50% or higher percentage. The items most preferred by the respondents were concealers, color lotions, and BB creams; 60.8% considered them positive. This showed that basic color cosmetics had already been established as one of the essential goods for men. In contrast, the respondents had slightly negative perception about items like mascaras, eyeliners, and eyeshadows. Overall, those who were young, unmarried, and city dwellers had positive perception about such cosmetics by and large. The above data will be able to be used to develop various makeup goods for male consumers oriented toward success and implement diverse marketing strategies, thereby activating the beauty market for males.

Purpose: This article was to study the optical and surface properties of soft contact lenses (SCL) exposed to eye make-ups. Methods: Rates of the light transmission of etafilcon A (HEMA based hydrogel lens) and lotrafilcon B (silicone based hydrogel lens) exposed to four different cosmetics over time were investigated. After cleansed with multi-purpose solution (MPS), rates of the light transmission and surface change of lens that were exposed to the cosmetics for 7 consecutive days were analyzed. Results: Visible light transmissions of all lenses exposed to cosmetics decreased to 93.35% (HEMA based hydrogel lens) and 90% (silicone based hydrogel lens) compared with those of the fresh SCLs, such as 97.8% and 96.4%, respectively. It was found that cosmetic residues from powder eye shadow and mascara attached to the lenses were not removed completely when cleansed with MPS. Especially with silicone based hydrogel lens, we found a decrease in visible light transmission of the lens and noticeable particles on lens surface imaged by SEM. Conclusions: Depending on types of eye make-ups and contact lens materials, make-ups were not completely eliminated with current cleansing methods and that caused a decrease in optical property and a change in surface property of the lenses.

Using cylindrical paper pot nursery method, three kinds of commercial tomatoes 'Dafnis', 'DOTAERANG DIA' and 'Maescala' were grafted onto a commercial rootstock 'B blocking'. From 10 to 40 days after graft-take, growth traits of seedlings were investigated by 0.5, 1.0 and 2.0S treatments of standard nutrient solution(S) for seedling growth, and top to root ratio(TRR), compactness(CP) and Dickson Quality Index(DQI) were calculated. Two weeks after transplanting of the seedlings under three different night temperature targeting to 10, 15, and $25^{\circ}C$, which were not precisely controlled, the relative growth rate (RGR) was investigated. The quantitative growth traits of grafted seedlings increased with increasing fertilizer concentration, and various range of seedling size could be produced. Compactness and DQI were significantly regressed (Adj $R^2=0.9480$). Short-term RGR after transplanting was higher at 1.0S treatment of standard nutrient solution at the seedling age of 30 days and 40 days after graft-take(DAGT). DQI and RGR were significantly regressed linearly at respective fertigation strength. Specially the diminishing slope of RGR was lower at 1.0S fertigation strength with the increase of DQI than others. The results indicate that DQI could be applied as a quality index of grafted tomato seedlings and the relation analysis between DQI and short-term RGR also could be used to determine the good quality seedlings of grafted tomato grown in cylindrical paper pot.
