In the present study, an attempt was made to compare and analyze the changes in facial skin condition after application of cosmetics using basic cosmetic application methods and air brush of modern women using a skin analyzer and a dermoscope. The results of facial skin moisture measurement showed that the control group and the experimental group maintained a sufficient moisture content in the foreheads, both cheeks and chin except the nose. According to the findings of skin sebum measurement, there was no significant change in the forehead, both cheeks and the chin of control group-1, and the nose decreased below normal after the experiment. The forehead, right cheek, and chin were normal in control group-2, and the nose increased from normal to above normal 4 weeks after the experiment. The forehead, left cheek, and chin of experimental group-1 increased to normal after the experiment, and the forehead, right cheek, nose and chin of experimental group-2 remained normal after the experiment. The results of pH measurement revealed that the forehead of the control group decreased from normal to below normal, while the remaining portion did not show any significant change. The experimental group-1 showed normal values in all portions and the experimental group-2 showed normal values in the nose and both cheeks. Dermoscopic studies showed that skin condition of the control group and the experimental group were different depending upon the concerned skin areas. The skin changes before and after the experiment turned out to be consistent with the result of the skin analysis using a skin analyzer. The experimental group showed an improvement in skin condition after the experiment. To sum up, skin care using air brush is effective for moisturizing as the fine particles ejected through the nozzle improve adhesion and durability to the skin. In order to maintain a balance between moisture and sebum in the skin, it is expected that our findings will be more effective if manual operation is performed after spraying with air brush.

가로의 연결성이 상권 매출액에 미치는 영향에 대한 연구: 서울시 발달상권을 중심으로
장아영(Chang, Ah Young),강명구(Kang, Myoung Gu) 한국지역개발학회 2022 한국지역개발학회 학술대회 Vol.2022 No.5
This study aims to analyze the effects of the street connectivity on the sales revenue of Major Retail Areas in Seoul, South Korea. To measure the street connectivity, we use the street density and the intersection density. The properties of the street network are a key factor that influences the location of land uses and the local economy. Numerous studies have been conducted literature research of the effects of urban phenomena based on the street connectivity. However, the empirical analysis by estimating the street connectivity using spatial data was underdeveloped. Meanwhile, few studies of the retail economy have deliberated over the effect of street network, while the research was focused on socio-economic influences. Thus, it is operated for this study to analyze data which is exported from Open Street Map(OSM) to reveal that the street connectivity affects positively on the retail economy. This study explains the theory of the street connectivity and analyze the effect on sales revenue of the retail locales. The results of the multiple regression analysis model of this study shows that the higher the street density, the higher the sales revenue in the retail areas. These results empirically verify the reverberation on the retail economy in consideration of street connectivity. Though this, we find out how the street connectivity impact on the retail economy. The consequence of this study delineates economic outcomes of the street network structure.

보문 : Eye shadow 화장품에 첨가된 무기물질의 성분과 미세구조 분석
장아영 ( A Young Jang ),장병수 ( Byung Soo Chang ) 대한미용학회(구 대한미용과학회) 2010 대한미용학회지 Vol.6 No.4
In this study, we investigated the microstructure and element of the ingredients of three kinds of eye shadow with different color each other commonly in use for eye make-up using scanning electron microscope and energy disperse X-ray spectroscope. In the examination of golden peach eye-shadow under observation of scanning electron microscope, mica covered by titanium dioxide was observed in a form of thin section. The mica with pearly luster was mostly observed. In the examination of brown eye-shadow, the particles of the mixture were relatively even in size and homogenous in composition. It was found that the inorganic matters of the mixture had talc, iron oxide black and iron oxide yellow as main component. Among them, talc was a major component of most matters. In the examination of deep brown eye shadow, the mixture was homogenous with small particles covering the surface of silica. The flakes of round silica and talc were observed, which were relatively big in size. The major component of it was iron oxide black with lumps in a form of thin flack around them. The inorganic elements comprising the golden peach eye-shadow were carbon, oxygen, magnesium, aluminum, silicon, potassium, titanium and iron. Silicon accounts for 13.32%, the largest portion, and iron 0.67%, the least portion. The brown eye-shadow were carbon, oxygen, magnesium, silicon and iron. Among them, silicon accounts for 17.31%, the largest portion, and iron 2.58%, the least portion. The deep brown eye shadow were carbon, oxygen, sodium, magnesium, aluminum, silicon, sulfur and iron. Among them, iron accounts for 45.37%, the largest portion, and aluminum 0.20%, the least portion. According to the results of elemental analysis of the inorganic matters comprising three types of eye shadow used in the present study, it was found that there are differences in the content of inorganic minerals which create a luster or chic effect depending upon the function of eye make-up.
