  • Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of Acanthopanax senticosus extract (AS) on hepatic ischemia-reperfusion. To explore the protective effects of A. senticosus extract injection (ASI) on hepatic ischemia-reperfusion injury rats animal model were used. After the development of HIRI by using clamping method rats were then randomly divided into five groups. Different doses of AS were administered in HIRI rat model. The level of ALT, AST, and MDA content in serum were detected in sham and HIRI groups. The activity of SOD, MPO and $Ca^{2+}-ATPase$, content of MDA, and cAMP in hepatic tissue were also measured. Expression of Bcl-2 and Bax protein were detected by immunohistochemical staining method. Compared with sham group, ASI has the protective effect on the HIRI model in rats. Blood levels of ALT, AST, SOD, MPO, and MDA were significantly lower in ASI group compared with HIRI. Indeed SOD and $Ca^{2+}-ATPase$ activities, MDA content, and cAMP level were improved in ASI group. Furthermore, Bcl-2 and Bax protein were improved in ASI group compared with only HIRI group. These results suggest that AS may provide potential ameliorative therapy by inhibiting the damage signaling mechanism in hepatic ischemia/reperfusion injury model.

  • The purpose of this study was to examine the need of the eyelash design area and the changes of an eye image according to eyelash design. Methodology included both a theoretical research and an empirical research. The theoretical research reviewed previous researches and technical books. The empirical research divided eye shapes, complemented the defect of eye shapes, and examined resulting image changes. A mechanical way was performed for treatment because it was more efficient than a manual way. A J-curl type was used. Eye length was divided into five and the point was determined. The length and density of curl were changed in each point to maximize a treatment effect. As a result, eye images were changed as follows. First, round eyes became stable. Slit eyes became vivid and soft. Wide-set eyes became intelligent and narrow-set eyes became smooth. Large eyes were naturally gradated and small eyes became larger. Double-eyelid eyes became stable and elegant and single-eyelid eyes became gentle and soft. Bulging eyes became easy and soft and sunken eyes became smooth. Peaked eyes became gentle and soft and sleepy eyes became strong and vivid. Based on the findings, eyelash design can play a role in changing an image according to eye shapes. In particular, a speed eyelash extension device to extend eyelash can reduce working hours and gradate only by angle control. It can complement the defect of eyes according to the design of each shape and change into a better image.

  • Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of combined treatment of Ginko biloba leaves extract and vitamin C (GLEVC) on hepatic ischemia-reperfusion injury. To explore the protective effects of GLEVC on HIRI rats model were tested. After the development of HIRI by using clamping method rats were then randomly divided into four groups. Different doses of GLEVC were administered in HIRI rat model. The level of ALT, AST, SOD and MDA content in serum were detected in HIRI groups. Moreover, the activity of SOD, content of MDA, and GSH in hepatic tissue were also examined. Bcl-2 and Bax protein expression were detected by immunohistochemical staining method. Compared with sham group, GLEVC has the protective effect on the HIRI-induced model. Level of ALT, AST, and MDA in blood were significantly lower in GLEVC group compared with HIRI-induced group. Moreover, SOD activity and GSH were increased in GLEVC group whereas MDA content was reduced by GLEVC treatment. Furthermore, HIRI-induced Bax protein was reduced upon GLEVC treatment, whereas Bcl-2 protein expression was enhanced. These results demonstrate that GLEVC treatment may provide potential ameliorative therapy by reducing damaged signaling mechanism in hepatic ischemia/reperfusion injury model.

  • Recently the hair style of Michelle Obama, the world's most recognized First Lady of the United States has been loved by the public with her optimistic confidence and as a fashion leader. For Michelle Obama's hair styles by length, a medium-short cut style was expressed in various ways to show her strong will by exposing the forehead, an elegant image by asymmetry hair, or a progressive image by a short volume hair cut. A medium cut style expressed an elegant and intelligent image in shoulder-length and a trendy image using a side parting. A updo hair style produced young, womanly, and casual images using twisting, binding, typing up, and rolling technique according to situations. For hair styles associated with her roles, when participating as a diplomatic delegate, she expressed the President's helpful partner by a soft and womanly image using bobbed hair and half updo technique. For the participation in state occasions, her hair styles were examined in three situations. First of all, she mainly had a neat style, exposing her forehead in official schedules as a political partner to create an intelligent and high-class image. Second, she expressed a strong will with a medium-short style during an election campaign. Finally, she showed an elegant and refined hair style in consideration of T.P.O. during social activity. Michelle Obama overcame her hair's handicap, grasped her images associated with hair length, and expressed hair strategically according to her roles as the first African-American First Lady of the United States.

  • This thesis aimed to reduce the differences of hair color when hair coloring, so it researched the differences & changes in hair color before shampoo v.s. after shampoo and dry on different heat processes when acid hair color dyeing. Five hair color dyes (Y, R, B, G, Br) manufactured by two different corporations were used. The acid hair color dyes were tinted on black and bleached hair pieces subjected to 3 different heat process; 1. Normal Temperature($25^{\circ}C$, 30min.) / 2. Heating($40^{\circ}C$, 15min.)+Normal Temperature($25^{\circ}C$, 15min.) / 3. Heating($40^{\circ}C$, 30min.). Color numbers were divided by NCS value, chroma, and hue. Statistical averages were derived and t-test was conducted using SPSS V12. Hair color differences and changes were drawn on an NCS chart using Photo Shop PS. The conclu is; If acid hair colorings are separated by a heating process, hair value & chroma change before shampoo vs. after shampoo & dry regardless of the color of hair and the heat process. Hue is not changed or shifted counter clockwise NCS color circle, but some exceptions, and it's the same when the total heat process results are combined. Black hair's value shifted downward and chroma left, and hue stayed either neutral or one color or it shifted counter clockwise on NCS color circle. Bleached hair's value shifted upward and chroma right, and hue stayed one color or shifted counter clockwise, but some exceptions. And it can be shown on NCS chart.

  • 국내 성인 여성 330명을 대상으로 코로나19로 인한 마스크 착용 이전/이후 메이크업 정도와 메이크업 만족도의 상관관계, 여기에 작용하는 메이크업에 대한 의무적/자발적 목표지향적 태도의 조절효과를 알아보았다. 코로나19 이전 메이크업 만족도에 유의한 변수는 립메이크업(p<.001)이었고 코로나19 이후 유의한 변수는 아이브로우메이크업(p<.002)이었다. 코로나19 이전/이후 메이크업 정도와 메이크업 만족도 사이에 작용하는 의무적 목표지향적 태도의 조절효과는 유의하지 않았으나 자발적 목표지향적 태도의 조절효과는 코로나19 이전(p<.000)과 이후(p<.000) 모두 유의했다. 코로나19 이전/이후 메이크업 정도 차이는 코로나19 이후 메이크업 정도가 이전보다 낮은 것(p<.000)으로 나타나, 메이크업이 스스로의 만족을 위한 것이라고 믿는다면 메이크업 정도가 만족도에 유의하지만 실제 행동은 마스크 착용 이후 메이크업 정도가 줄었다. 이상의 내용이 미용·화장품 업계의 마케팅 자료로 활용되기를 기대한다.
