We compared the quality of 'Fuji' apples (Malus ${\times}$ domestica) from trees whose leaves were not removed (no artificial defoliation; NAD) with apples from trees that underwent early defoliation (ED, treated in mid September and early October) and conventional defoliation (CD, treated in early and mid October). The experiment was conducted in three consecutive years using 15-year-old 'Fuji' apple grafted on Malus prunifolia. Fruits were harvested on November 7, 16 or 12 in 2011, 2012 and 2013, respectively. Compared to NAD treatment, ED and CD treatment reduced the fresh weight by 4.7% and 0.6%, respectively. The soluble solids content of NAD apples ($14.4^{\circ}Brix$) was slightly higher than that of CD ($14.1^{\circ}Brix$) and ED ($14.0^{\circ}Brix$) apples. Soluble sugar content, flesh firmness, water-core index, and titratable acidity were not affected by defoliation treatment regardless of treatment timing. The skin blush index of NAD apples (2.3) was inferior to that of CD (3.3) and ED (3.4)- treated apples. Furthermore, artificial defoliation treatments increased skin redness ($a^*$) and yellowness ($b^*$) and significantly improved the degree of skin blush compared to NAD fruits.

본 논문은 사용자 사진에서 ASM(Active Shape Model)을 이용하여 얼굴의 각 특징 점을 추출하고, 추출 된 특징점을 이용하여 화장할 부분의 영역을 생성 한다. 기존의 가상 메이크업 프로그램에서는 사용자가 수동적으로 몇 개의 특징 점을 정확히 선택해야 하는데서 불편함을 초래했다. 본 논문에서 제안하는 가상 메이크업 프로그램에서는 ASM을 이용하여 사용자의 입력을 필요로 하지 않는다. 자연스러운 화장 효과를 표현하기 위해서 기본적인 알파 블렌딩을 각각 화장품의 특징에 맞게 변형하여 사용자 피부색과 화장품의 색을 혼합한다. 얼굴 윤곽, 눈, 눈썹, 입술, 볼의 영역을 생성하고, Foundation, Blush, Lip Stick, Lip Liner, Eye Pencil, Eye Liner, Eye Shadow 종류의 화장을 할 수 있게 구현하였다.

Purpose : This study was aimed to analyze the effects of cosmetics containing Persicaria perfoliata water extract (PPWE) on the skin moisturizing and improvement of skin condition in clinical trials. Methods : Clinical trial was conducted for five weeks after IRB approval at Dong-Eui University. Out of a total of 64 people, 15 people each were assigned to four groups as follows; control group A, B, C and the experimental group A that using cosmetic containing PPWE. Skin condition was measured two times, before and after clinical trial, by a professional skin analyzer, SDM (skin diagnosis system). Moisture and oil value of participants was analyzed twice, each morning and evening, using a portable device on their cheeks. In addition, the survey was investigated subjective satisfaction on change in skin condition and the satisfaction on the use of cosmetics. Result : The experimental group exhibited subjectively significant changes before and after clinical trials on skin its dryness (p=.039), blush (p=.017), and redness (p<.001). In addition, subjective evaluation was also the highest satisfaction in aspects of number of application (p=.003), amount of application (p=.002), moisture maintenance, and skin scratching frequency. The satisfaction on the use of cosmetics was the highest in the intention to repurchase (p=.045), recommendation willingness to others (p=.020), and intention to use various products (p=.001). Skin moisture of the clinical trial participants using the SDM, moisture level and elasticity of the experimental group increased by 12.94 and 10.28. Moisture level, which was measured by a portable device, was the most potently increased in the experimental group. Conclusion : Consequently, PPWE containg cosmetics exhibited the effects of moisturization and attenuated skin dryness in clinical trials, which might be utilized as a fundamental data to develop numerous lines of cosmetics.

This study aimed to assess the satisfaction levels of adolescents with beauty programs, investigate the factors influencing them, and present foundational insights for designing cosmetics and beauty education initiatives tailored to adolescents. Specifically focusing on the "Safety and Use Education for Youth Cosmetics" program implemented in Gwangju Metropolitan City, it examined the satisfaction of participants, including students, instructors, and school teachers involved in the education. The study was based on action research, a qualitative methodology. The conclusions are as follows: First, participants gained knowledge and information encompassing various aspects of cosmetics, such as types, expiration dates and usage span, face wash and skin types, shampooing methods, scalp care, role and significance of sunscreen, skin trouble management, and identification of skin type, through cosmetic education programs. Second, participants learned about techniques such as eyebrow trimming, eyebrow shape correction, facial contour correction, skin blush supplementation, color makeup, personal color, and tattooing. Third, there is an urgent need to develop different educational teaching resources suitable for implementation across elementary, middle, and high schools. Fourth, it is necessary to cultivate higher-quality instructors in this digital age. Fifth, it is crucial to explore new methods of delivering beauty education to adolescents. We hope the insights gleaned from this study will serve as useful foundational data, albeit modest, fostering new beauty trends amidst the challenging landscape of youth education.

Objectives : We performed a retrospective study to verify the effects of Chungan-tang and acupuncture in acne patients.Methods : This study included patients with facial acne who visited to six branch of clinics in 2014. They were evaluated by Korean Acne Grading System (KAGS) before and after treatment.Results : The average grade of KAGS was 4.02±1.120 at before treatment and 1.30±0.867 at after treatment. 64 patients were classified as three groups by treatment period and KAGS grade significantly decreased in all groups. Six skin symptoms such as heat, blush, dryness, itch, prick, pain also significantly improved.Conclusions : This results may provide that Korean medical treatments including Chungan-tang and acupuncture have effects on improving acne.

매실(Prunus mume Siebold et Zucc.)은 장미과에 속하는 과수로 한국에서는 전통적으로 기침이나 소화불량의 민간 요법 과실로써 사랑받아 왔다. 1993년 국립원예특작과학원 배시험장에서 '옥영'과 '임주'를 교배하여 그 중 과실이 크고 과형이 좋으며 풍산성인 '옥주' 품종을 2006년에 선발, 육성하여 새로운 품종으로 등록하였다(등록번호: 4556호, 2013.6.18). '옥주' 품종의 만개기는 '옥영'보다 4일, '임주'보다 2일 빠르며 꽃잎색은 분홍색이고 꽃가루는 없다. PCR을 이용한 자가불화합인자 분석결과, 옥주의 자가불화합성 인자는 $S_3S_6$이었다. '옥주'의 성숙기는 6월 하순으로 과실은 원형이며 봉합선이 얕다. 평균과중 18.5g이며 가용성 고형물 함량은 $7.66^{\circ}Brix$, 산 함량은 4.81%, 과피색은 녹색이지만 햇빛을 많이 받는 쪽의 과실 일부가 적색을 띄기도 한다. 또한, 검은별무늬병과 세균성구멍병의 발생이 비교적 적고, 수량성이 높아 재배농가들이 새로운 품종을 선택할 수 있는 기회를 준다는 점에서 그 의의가 클 것으로 생각된다.
