A Study on the Waxing Effectiveness of Sugaring
Shinhwa Kang(Shinhwa Kang),Jiyoung Lee(Jiyoung Lee) J-INSTITUTE 2022 Protection Convergence Vol.7 No.2
Purpose: The pursuit of beauty, which started from ancient times, is a basic human need, and many studies on the attractiveness of appearance are on the rise, and such research on human beauty is an important public value. Recently, interest and demand for waxing are rising, but the level of professional education on waxing is low and the understanding of skin changes and follow-up care after waxing is low, so the need for research on waxing is emerging. The purpose of this study is to find out the difference in skin condition and hair growth rate after Brazilian treatment according to the type of waxing and to present it as basic data, and to contribute to the public value in beauty culture. Method: The subject of this study was a woman in her early 20s who had no experience with waxing, and waxed the bikini area between June and August 2022 using sugar wax and hard wax respectively. For 4 weeks after Brazilian waxing, the skin condition(including ingrown hair, folliculitis, etc.) and hair growth length were compared and analyzed at weekly intervals. The results were analyzed after the mixed study using clinical trials and interview methods. Results: As a result of comparative analysis of the skin condition and the length of the growing hair at weekly intervals after waxing, the condition of the skin showed that ingrown hair and inflammation occurred in the area where the sugar wax was applied, and the hair growth rate was slow. In the area treated with hard waxing, ingrown hair did not occur compared to sugar waxing, and the number of inflammations was significantly lower. The growth rate of cross-section hair was faster than that of sugar waxing, and it was confirmed that the thick-ness of the hair also grew thicker. Conclusion: Sugar waxing had excellent effects on hair removal and hair thickness reduction, such as lower skin dryness, redness, and irritation of pores compared to hard waxing, but follow-up care is expected to be very important. If follow-up care is not performed properly after Brazilian waxing, it is thought that the risk factors for ingrown hair and folliculitis may be high.

This paper conducts a study on design of centrifugal blood pump in ECMO Condition. To obtain accurate simulation result, numerical investigation was performed steady and unsteady simulation. Based on numerical result, the unsteady simulations are more accurate than the steady results. Therefore unsteady simulation is more appropriate for future numerical investigation about Prototype. The maxium head value error occur between design curve with prototype unsteady simulation result. This error is considered loss problem at volute. Future paln study deep into a volute design.
