Objective : The purpose of this study was to explore the correlation between efficacy and various factors of the acne patients. Method : We reviewed 30 acne patients who visited Allergy/Derma-cosmetic Clinic at Kyung Hee Neo Medical Center from June, 2006 to December, 2007 and were treated with herbal medicine and acupuncture for 4 weeks. We investigated premenstrual aggravation of acne, facial burning sensation, constipation, Heart Rate Variability(HRV) results and regional distribution of acne. And we evaluated inflammatory acnes according to the Korean Acne Grading System(KAGS). Results & Conclusions : 1. The average age of total patients was 23.0 years old. The most frequent age group was 21-25 years old. Patients evaluated as KAGS Grade 2 were most common. 2. In total patients, inflammatory acne were reduced significantly after 4 weeks of treatment. 3. The result of analysis on premenstrual aggravation of acne, facial burning sensation and constipation, there weren't any difference of treatment results on statistical meaning. 4. The results show that there were significant correlations between the Low Frequency at HRV and the rate of acne reduction. (Pearson correlation = -0.565) 5. If the distribution of acne did not involve the T-zone of the face, chest, or back of the body, inflammatory acne were significantly decreased after 4 weeks of treatment.

Objective : The purpose of this study is to study trends in Western(North America and Europe) medical treatments for the acne vulgaris. This study analyzed research on acne vulgaris in PubMed. Methods : We searched PubMed related the latest medical treatments for acne vulgaris. We analyzed 21 research papers and examined published journals, years, countries, and their methods, results, interventions, participants, periods and instruments of assessment. Results : The method of studies was mostly double-blind, randomized controlled trial. There were research papers concerning treatment with light-lazer, topical agents, and oral contraceptives. There were more positive results compared to negative results for efficacy of treatment. The median for number of participants was 364.0 persons. The median for periods was 67.8 days. Assessment for outcomes were lesion counts, adverse effects, VAS, etc. Conclusions : It is necessary to study latest trends of Western medical treatments for acne vulgaris and understand strengths and weaknesses of those. It will be helpful to more in-depth develop clinical treatments of Oriental Medicine for acne vulgaris.

최근 뷰티 산업은 급격한 성장과 혁신으로 빠르게 발전하였으며, 코로나19 팬데믹으로 인한 마스크 착용 및 비대면 생활의 증가와 같은 생활 양식 변화에 따라 새로운 전환을 겪고 있다. 본 연구는 온라인상에 나타난 소비자의 피부에 대한 의견을 분석하여 코로나19 팬데믹 이후 뷰티 산업의 변화를 수요 측면에서 이해하고자 하였다. 이를 위해 2017년부터 2022년까지 소셜 미디어에 게재된 게시글 중 '피부 고민'을 포함한 96,908개의 게시글을 수집하고 이를 구조적 토픽모델에 적용하여 피부 관련 주제를 도출하였다. 분석 결과, 소비자가 고민하고 있는 피부 관련 주제는 총 22개로 구분될 수 있음을 확인하였으며, 이들 주제는 크게 뷰티 제조업, 뷰티 서비스업·연관산업, 피부고민, 기타 등 4가지 유형으로 구분될 수 있었다. 또한 본 연구는 분석 기간을 코로나19 팬데믹의 확산 양상을 기준으로 7개 단계로 나누고 각 토픽의 비중이 어떻게 변화하는지를 상승, 하강, 일정, 진동으로 구분하여 보았다. 코로나19 팬데믹 전과 후 시점에 대하여 주제별 비중의 변화 양상을 분석한 결과, 피부 고민 중 피부 트러블(여드름)과 이와 관련된 제품(스팟패치)은 상승 분야로, 뷰티 연관산업 중 성형외과와 한의원은 하강 분야로, 뷰티 제조업 중 수분 마스크팩, 메이크업 제품은 큰 변화가 없는 일정 분야로 나타났다. 또한 코로나 발생기간 내에서 팬데믹이 최고조에 달한 시기에는 바디케어 제품과 관련된 토픽이 급증하는 것을 확인할 수 있었다. 본 연구의 결과는 뷰티 산업의 수요 변화에 대응하여 기업이 제품 개발, 마케팅 전략을 수립하는 데에 활용될 수 있으며, 팬데믹 발생 시 정부가 경제적 지원 정책을 수립하는 경우 정책 추진의 근거로서도 활용될 수 있을 것으로 기대된다.

본 연구에서는 중국 하이난성 지역 10대~50대 남녀를 대상으로 메디컬스킨케어센터를 내원한 환자들을 중심으로 성별에 따른 피부유형 및 피부관리실태, 피부관리 인지도, 만족도를 검증하고자 한다. 이에 피부관리 실태, 피부관리 인지도, 피부관리 만족도 등을 2020년 12월 21일에서 2021년 1월 9일까지 위쳇(WeChat), 왠쥬엔씽 프로그램(wenjuanxing program)을 이용하여 총 328부를 조사하여 SPSSWIN 21.0 프로그램을 사용하여 분석하였다. 피부유형 및 피부관리실태, 피부관리 인지도 및 만족도는 빈도분석(Frequency Analysis)을 실시하였고, 피부관리 인지도와 만족도 신뢰도는 Cronbach's α의 계수를 구하였다. 성별에 따른 피부유형 및 피부관리실태, 인지도, 만족도의 관련성은 카이스케어 검정(χ²)과 t-test를 실시하였다. 분석결과 성별에 따른 피부타입은 여성은 건성피부, 남성은 지성피부이고, 피부고민은 여성은 기미색소, 남성은 여드름피부로 성별에 따라 차이가 나타났다. 이러한 문제성피부관리는 남녀모두 홈케어가 높았고, 다음으로 여성은 피부과, 남성은 약국으로 유의미한 차이를 나타내었다. 진행기간은 남녀모두 1~3년 미만이고, 효과적인 피부 개선 방법으로는 남녀모두 좋은 생활습관, 레이저 순이었다. 병원 선택 시 고려 사항으로는 유명한 체인병원이고, 관리 시 중요 사항은 의사나 피부관리의 전문성을 고려한 것으로 응답하였다. 피부관리 및 치료 인지도는 여성은 외적, 남성은 내적이 높았고, 피부관리 만족도의 차이는 여성은 서비스, 남성은 효과로 나타났으며, 관리만족도는 남성이 여성보다 유의미하게 더 높은 것으로 나타났다. 결론은 중국 메디컬스킨케어센터를 내원한 환자들이 성별에 따라 피부유형 및 피부고민, 피부문제, 피부관리 방법, 피부관리 만족도에 차이가 있는 것으로 분석되어 다양한 제품 개발 및 체계적인 관리프로그램의 필요성을 제시하였다.

The purpose of this study was to evaluate bacteriocin activity against human flora. Lactobiocin, a bacteriocin produced by Lactococcus sp. HY 449, inhibited the growth of Starphylococcus epidermidis, Starphylococcus aureus, Streptoccoccus pyogenes and Propionibacterium acnes. When crude bacteriocin was added to indicator cells during logarithmic growth, the optical density(O.D 650nm) of cells without bacteriocin increase after 5h of incubation. Whereas in the presence of bacteriocin, the O.D of cell suspensions decreased. The similar patterns were observed for absorbance readings at 280 nm and 260 nm. The release of cellular components when cell were treated with Lactobiocin suggests some degree of membrane damage or cell lysis. Scanning electron microscopy of cells following treatments with Lactobiocin in PBS buffer revealed disruptures of cell morphology. These results indicate that bacteriocin appears to cause cell lysis of tested strains. In cytotoxicity on human fibroblast, LD$\_$50/ of Lactobiocin was ca. 50 mg/ml and no change was observed cell proliferation at the same concentration. Any irritation and allergic reaction did not observed when evaluated by human patch test for Lactobiocin.
