This study was performed to examine if the effects of collagen supplementation from pork skin could improve the sex steroid hormone, serum lipid and skin crack in Korean middle-aged women. Middle-aged women (40-55 years) who were not diagnosed with any type of disease were included in this study and thirty subjects were randomly assigned to a control group (n=15) or a collagen supplemented group (n=15). The collagen supplemented group ingested collagen flour 2 g, 3 times a day for 12 weeks. We measured serum collagen, estrogen, estradiol, estriol, progesterone, total cholesterol, triglyceride, HDL-cholesterol and LDL-cholesterol concentration. The collagen supplementation group had significantly increased serum collagen (p<0.05) compared with the control group. In addition, skin crack was improved. But, there were no differences for sex steroid hormone and lipid profile in control and collagen supplemented groups. The result of the present study demonstrated that supplementation of 6 g collagen per day for 12 weeks can give beneficial effects on skin crack reduction and serum collagen concentration.

This study compared the results of previous studies with scientific and systematic analysis of scalp care effects through Meta-analysis. The selection of research papers was carried out on data we collected using `scalp` and `hair` as search terms targeting Master`s and doctoral thesis and journals published in Korea from January 2008 to December 2016. The overall effect size of the variables related to scalp care effect can be interpreted as a `large effect`. The size of blood pressure control effect of physiologic variables is a moderate effect, while the effect of physiologic variables is a big effect, and the psychological adjustment effect of physiologic variables is a big effect. The size of the hair improvement effect of psychological variables according to the scalp care method was a `big effect`, and the correlation effect between sub-variables is the largest in the electric stimulation parallel therapy followed by hand massage parallel therapy, other hair therapies, and MTS parallel therapies. An effect size analysis through regression analysis related to continuous variables was closer to the recent publication, and the larger the effect size of variables related to the scalp care effect. In conclusion, scalp care effect through meta-analysis showed effectiveness in blood pressure control effect size of (both systolic and diastolic blood pressure) physiological variables, the hair improvement effect size (scalp keratin improvement, hair thickness, hair density, number of hair, moisture, and oil) of physiological variables, and the psychological adjustment effect size (stress) of physiological variables.

본 연구는 성인 남,녀를 대상으로 소프트 왁싱, 하드 왁싱 슈가링에 대한 추구혜택이 재이용의도에 미치는 영향에 대해서 알아 보는 것에 목적이 있으며 이를 통해 왁싱을 처음 접하는 일반인들에게 유용한 정보가 되는 것에 연구의 의의가 있다. 연구방법으로는 부산과 영남권에 거주하는 17세 ~ 40대 왁싱 경험이 있는 남,녀 422명을 대상으로 연구자가 직접 설문을 진행하였으며 분석방법은 교차분석, 독릭표본 t-검정, 상관분석, 선형회귀분석, 복수응답은 Multiple response test를 이용하여 자료를 분석하였다. 연구결과에서는 왁싱 추구혜택이 재이용의도에 미치는 영향에 대한 결과를 살펴보면 부위별 왁싱 추구 점수, 왁싱 혜택 총 점수(r=0.389, p<0.001) 및 재이용의도 총 점수(r=0.214, p>0.001)와 유의한 양의 상관성을 보였으며, 부위별 왁싱추구혜택 및 재이용의도의 관련성을 보면 바디(팔, 다리)를 제외 한 항목들을 유의한 양의 관련성을 나타내었다. 왁싱 추구혜택이 재이용의도에 미치는 영향에 대한 결과를 살펴보면 페이스 왁싱, 브라질리언 왁싱 및 왁싱 혜택 총 점수 모두 재이용의도에 유의한 영향을 주는 것으로 나타났다. 연구의 내용을 통해 아직 슈가링의 인지도는 낮으나 호의적인 감정 및 재이용의도가 높고 예민한 부위일수록 추구하는 것을 알 수 있었다. 따라서, 왁싱을 접하는 소비자들에게 유용한 정보를 제공하고 향후 왁싱 관련 연구의 기초자료를 제공할 수 있을 것으로 기대한다. The aim of the study is to investigate the effect of the benefit of soft waxing, hard waxing, and sugaring waxing on intention to reuse in Korean adults, and to provide useful information to people who are new to waxing. As a research method, from May 1, 2019 to August 30 (17 weeks), we surveyed 422 subjects between 10 and 40 years old who lived in Busan and Yeongnam area and experienced waxing. In statistical analysis, Cronbach's alpha was calculated for reliability test, and Chi-squared test, independent t-test, correlation analysis and linear regression analysis were used. Multiple responses were analyzed using multiple response test. In the result of the effect of waxing benefit on intention to reuse, there was a significant positive correlation of waxing seeking score by body part, total waxing benefit score(r=0.389, p<0.001), and total score of intention to reuse (r=0.214, p>0.001) with intention to reuse. There was also a significant positive correlation between waxing benefit by body part and intention to reuse, except arms and legs. In the result of the effect of waxing benefit on intention to reuse, face waxing (β=0.106, p<0.001), Brazilian waxing (β=0.221, p<0.001) and total waxing benefit score (β=0.321, p<0.001) had a significant effect on intention to reuse. In the present study, awareness of sugaring waxing was low but favor and intention to reuse were strong, and the subjects sought sugaring waxing for sensitive body parts. Thus, would provide useful information for consumers new to waxing, and also basic information for studies on waxing.

This study examined the US adolescents' purchasing behavior of cosmetics, thereby having aimed to arrange academic basic data for the economic movement of K-beauty. To achieve this research objective, a questionnaire survey was conducted targeting American adolescents from the 9th grade to the 12th grade who dwell in New York of the United States. The main results of this study are as follows. Most US adolescents themselves directly bought cosmetic products. Also, there was a response as saying that SNS such as Facebook has a great effect on the cosmetics purchasing behavior. More than 89% of the American adolescents gave a response as saying of not buying given not satisfying oneself even if being a product of being advertised by a favorite star. The cosmetic product was bought the most at a cosmetics brand shop(50.2%). Rather than price or brand, the skin fitness(59.2%) was recognized to be important in purchasing cosmetics. The information related to cosmetics was obtained the most from internet personal broadcasting such as YouTube, Twitch and Ustream. Seeing these findings, there is a need to consider the demographic features and psychological characteristics as well as the biological aspect along with the importance of gender given making use of a marketing strategy for K-beauty.
