As Korea's representative medical text, "Donguibogam" reveals Korean Medicine's unique perspective on the human body. The text also contains abundant resources related to skin, leading to diverse researches on the subject today. In this paper, authors tried to elicit values of "Donguibogam" in the general cosmetics field, through literature review. First, prescriptions related to main functions of modern cosmetics (anti-aging, whitening, and moisturizing) were classified. In relation to anti-aging, concepts such as 返老 (reversing aging), 還童 (to become young again), 皺 (wrinkle), and 皮急 (tense skin) were extracted and 69 examples of treatments were introduced. For whitening care, 41 treatments were mentioned on hyper-pigmentation and general complexion. Concepts related to moisturizing included expressions such as 潤肌膚 (hydration of skin) and 光澤 (glow), induced by 48 treatment prescriptions. Second, cosmetics related prescriptions were classified according to the application methods of modern cosmetics. 78 prescriptions of cleansing category included washing-off local area with herbal liquid, bathing, washing-off after steaming, and soaking the body in the herbal liquid. Total of 308 topical application prescriptions covered the conditions of various skin inflammations, scalp illnesses, and etc. In conclusion, this research examines the value of "Donguibogam" as a useful of skincare. Further studies are expected to extend our understanding of the field.

본 연구에서는 건강한 성인 여성을 대상으로 인삼 추출물을 함유한 스킨케어 제품의 시료 제시 방법과 여성들의 삶의 질 개선 효과 간의 상관 관계를 분석하였다. 삶의 질이란 질병이나 건강 상태가 일상생활에 미치는 신체적, 정신적 그리고 사회적 영향에 대한 개인적인 반응을 나타내는 개념이다. 이에 저자들은 45명의 건강한 성인 여성을 두 그룹으로 나누어 한 그룹(Group A)에는 브랜드 고유의 패키지를 유지한 인삼 크림 시료를 제공하였고, 다른 그룹(Group B)은 브랜드와 제품명을 알 수 없는 하얀색 통에 담은 동일한 시료를 제공하여 8주간 사용하게 하였다. 피부 관련 삶의 질 평가는 Skindex-16 설문지를 사용하여 시험 초기와 4주 후, 8주 후에 걸쳐 시행되었다. 시험 참여를 중지한 2명의 피험자를 제외한 43명의 Skindex-16 초기값의 평균은 22.70 ± 4.82점이었다. 8주 후, 그룹 A의 Skindex-16 지표는 초기값 23.30 ± 5.14에서 20.20 ± 4.83으로, 그룹 B는 22.17 ± 4.58에서 20.52 ± 3.60로 통계적으로 유의한 정도로 개선되었다. 세부 항목에서는 그룹 A의 ‘증상’ 항목이 4주 후, ‘감정’ 항목이 8주 후에 통계적으로 유의하게 개선되었으며, ‘기능’ 항목은 어느 그룹에서도 통계적으로 유의한 변화가 관찰되지 않았다. 또한, 총합과 세부 항목 모두 측정 시기 및 그룹에 따른 교호작용은 통계적으로 유의한 차이가 확인되지 않았다. 본 실험을 통해 인삼 크림이 포함된 스킨케어가 건강한 성인 여성의 삶의 질에 긍정적인 영향을 줄 수 있음을 확인하였으며, 스킨케어 행위 자체가 패키지에 대한 영향보다 삶의 질의 개선에 주는 영향이 큼을 추측할 수 있다. 장기적으로 ‘삶의 질’이란 기존의 피부과학 지표의 개선과 주관적 만족도의 개념을 넘어 신규한 화장품 효능 영역으로 추가적인 연구가 필요할 것으로 생각된다. This study is designed to analyze the effect of skincare using cosmetic containing ginseng extract, on improving quality of life (QOL) of healthy women, with blind testing. QOL is a concept that represents how one’s disease or health condition can physically, psychologically, and socially influence his or her daily life. The study was conducted to assess the effect of a ginseng cosmetic preparation on quality of life (QOL) using the Skindex-16 score, stratified by blind versus non-blinded option. 45 healthy women aged between 30 and 49 years with no skin disease were recruited for this study. Volunteers were divided into two groups. Group A (n = 22) received anti-aging cream with ginseng extract in the original packaging, which included the brand name and logo. Group B (n = 23) received the same cream in a plain white jar without any package decoration or logo. Both groups used the cream for 8 weeks. For the skin-related QOL assessment, Skindex-16 was used at baseline, forth, and eighth week. All volunteers except two dropouts in Group A completed the dermatology-specific QOL measure, Skindex-16, at baseline, after 4 weeks, and after 8 weeks of treatment with the provided samples. As a result, the mean score of 43 participants at baseline was 22.70 ± 4.82. There was a significant difference between the baseline score and the score after 8 weeks in both groups: The scores changed from 23.30 ± 5.14 to 20.20 ± 4.83 in Group A, from 22.17 ± 4.58 to 20.52 ± 3.60 in Group B. The “Symptom” subscale of Skindex-16 improved after 4 weeks and the “Emotion” subscale improved after 8 weeks in Group A. The “Function” subscale did not show improvement in either groups. Both groups showed no interaction effect between follow up time and groups in Skindex-16 and subscale. This research opens up the possibility of skincare using ginseng cream having a positive effect on QOL in healthy women. Moreover, one can predict that skincare ritual itself may have greater impact on the improvement of QOL, compared to the product packaging.

조가영(Cho Ga Young),엄재용(Eom Jaeyong),오민석(Oh Min- seok),김의종(Kim Eui-Jong) 한국태양에너지학회 2021 한국태양에너지학회 논문집 Vol.41 No.1

TThe Seoul Metropolitan Government announced a comprehensive plan for “Solar City, Seoul,” which is aimed at 1GW of power for 1 million households by 2022. Subsidies for the installation of BIPV(Building Integrated Photovoltaic Systems) in private buildings were expanded in 2020. It is therefore necessary to consider the building-integrated photovoltaic performance to harmonize with urban landscapes using renewable energy sources to realize zero-energy buildings. A field experiment was conducted to investigate the conditions of the BIPV, and the performance impact factors were analyzed. The results showed that the general glass, BIPV intermediate space, and internal surface of the BIPV temperature increased when insulation was added to the BIPV back panel in the spandrel part. The temperature increase in the Spandrel part is mainly caused by solar radiation, and the intermediate space temperature of the general glass rises higher than that of the BIPV module installation. The performance of the BIPV system was evaluated through a simulation. The simulation results showed that the temperature of the solar cell during BIPV generation depended on the energy balance of the effective solar radiation and ambient temperature. In the future, a comprehensive review of the module and material performances, such as the power generation and efficiency, will be required based on experimental verification.

Objectives: It is well known that genetic factors and environmental factors play major role in aging skin. In general, son and daughter take after their parents in appearance. But comparability of skin properties in Korean family has not been well estimated. So we evaluated the correlation of skin properties in Korean mother-daughter pairs. Methods: 10 couples of mother and daughter pair(n=20) participate in this study. Mothers and daughters were aged 50.6±2.459 and 23.8±2.15 years, respectively. Skin moisture, sebum, skin color and elasticity is measured using non-invasive method: Corneometer CM825, Sebumeter(MPA580), Mexameter MX18, Cutometer MPA580. Statistical analysis program we used is Minitab 14 Korea. Results: The Skin moisture of mother group was significantly higher than daughter group. And skin elasticity(R2) of the daughter group was significantly higher than mother group. In the results of correlation analysis between mother and daughter pairs, skin elasticity(R2) had high positive correlation(r=0.729, p=0.026). But skin moisture, sebum, melanin index, erythema index and skin elasticity(R5) did not be confirmed a significant correlation. Conclusions: Skin elasticity(R2) is the only factor that showed high positive correlation significantly in mother and daughter pairs. Mother and daughter share the genetic factors and environmental factors that influence skin aging. So, mother`s aging pattern will be a good guide for anti-aging of daughters.

영상미디어와 컨템포러리 발레의 융·복합 공연에서 나타난 환영성 - ‘초월(Transcendence)’ 사례연구

조가영 ( Cho Ka-young ) 한국무용과학회 2018 한국무용과학회지 Vol.35 No.2

본 연구자는 영상미디어와 융·복합 작품인 ‘초월’에서 환영성의 미학이 드러나는 장면들을 신체 즉 움직임, 시공간, 영상 미디어와의 상호작용과 연계하여 살펴보고자 하였다. 이는 영상미디어와의 융·복합 공연이 춤의 축소가 아닌 확장이라는 긍정적 견해를 수용하며, 춤의 미학적 특징을 규명해 봄으로써 융·복합 공연에서 춤이 갖는 예술적 가치를 높이고자 하는데 그 목적이 있다. 춤의 환영성은 역사 이전 시대, 제의의 형식에서 보여준 마술적 환영에서 낭만주의 시대 무대 기술과 결합된 낭만주의 발레의 초현실적인 환영성을 보여주었으며, 포스트모더니즘 이후 시각적 환영을 만들기 위한 다양한 시도가 이뤄졌다. 이후 춤은 무대라는 공간에서 영상미디어로 시공간이 확대되면서 디지털 환영성으로 치환되는 과정을 엿볼 수 있었다. 결과적으로 사례연구작품인 ‘초월’에서 보여지는 환영성은 서사적인 스토리와 리어스크린, 홀로그램, 샤, 구조물 등 기술적 장치와 움직임의 고유한 특징인 역동성, 무한복제와 변형이 가능한 영상미디어와의 복합적인 융합을 통해 ‘디지털 환영’이 드러남을 알 수 있었다. 이를 토대로 움직임과 영상과의 상호작용은 움직임 고유의 역동성을 새로운 방식으로 확장시키며 미적 가치를 지닌다는 알 수 있다. 본 연구가 앞으로 테크놀로지와 결합된 무용공연에 예술적 당위성을 부여하며 미력하나마 무용의 융·복합공연의 활성화에 도움이 되기를 바란다. The purpose of this study is to examine the scenes of ‘Transcendence’, a convergent work combined with image media, revealing the aesthetics of illusion in connection with the body, particularly the movement, time and space, and interaction with image media. Accepting the opinion of those positive about convergent performance combined with image media saying it is not the reduction of dance but the extension of it, this author aims to look into the aesthetic characteristics of dance and elevate the artistic value of dance in the area of convergent performance. The illusion of dance began as magical illusion in the prehistoric ages in the forms of rituals. In the age of romanticism, surreal illusion was shown in romantic ballet combined with stage technology. After the postmodernism, various attempts have been made to create visual illusion. After that, dance has been broadening its area from the space of a stage to image media in terms of time and space, and it is being substituted with digital illusion. According to the results, illusion found in the object of this case study, ‘Transcendence’, is shown as ‘digital illusion’ through the narrative, technological devices like the rear screen, hologram, sheer nylon, or structures, the unique characteristics of movement such as dynamism, and complex convergence with image media allowing limitless reproduction as well as transformation. Based on that, we can see that interaction between movements and images is equipped with aesthetic value as it extends the unique dynamism of movement in new ways. This author is hoping that this study will provide artistic appropriateness to dance performances to be combined with technology afterwards and contribute to vitalizing convergent performances for dance in any desirable way.

서울시 공공건축물 에너지 성능개선 리모델링 의사결정을 위한 에너지 사용량 데이터 분석

조가영(Cho Ga Young),유지현(Yoo Jihyun) 한국태양에너지학회 2021 한국태양에너지학회 논문집 Vol.41 No.4

The Seoul Metropolitan Government announced a 2050 greenhouse gas reduction strategy through the Green New Deal promotion and proposed a plan to achieve carbon neutrality through the five major areas of green building, green mobility, green forest, green energy, and green cycles. Among them, it is of utmost importance to prepare for the transition of low-carbon zero-energy buildings in the building sector, which accounts for 67% of the total energy consumption and 68.2% of greenhouse gas emissions in Seoul. In particular, 71.4% of the 454,000 buildings in Seoul are aged, and measures to expand to the private sector are needed to overcome the economic crisis caused by COVID-19. Therefore, to prepare a decision-making plan to improve the energy performance of existing buildings, the operation status and energy usage survey were conducted on public buildings with a total floor area of 3,000 ㎡ or more. The uses of the buildings were classified as cultural, educational, medical, office, and training facilities. A regression analysis algorithm was used to analyze the energy usage patterns and conduct a relative evaluation. The study results are intended to be used as a decision-making method for the energy diagnosis and remodeling of existing buildings.

조가영 ( Ga Young Cho ),염명훈 ( Myung Hun Yeom ),박성일 ( Seong Il Park ),조준철 ( Jun Cheol Cho ),유선혜 ( Sun Hye Yu ),최윤정 ( Yoon Jung Choi ),김종일 ( Jong Il Kim ) 대한화장품학회 2013 대한화장품학회지 Vol.39 No.3

본 연구의 목표는 한의학을 기초로 한 새로운 평가 방법을 이용하여 한방화장품의 효과를 분석하고자 하는 것이다. 한의학에서는 얼굴과 피부에 나타나는 현상을 분석하는 것이 환자의 질병과 체질을 예측하는 중요한 방법이었다. 내부 장기의 상태를 얼굴에 발현되는 증상과 피부를 통해 진단하는 방법을 한의학의 진단체계에서는 ‘망진(望診)’이라 한다. 이에 저자들은 지난 5년간 인삼농축크림을 사용한 피검자군 여성 11명과 대조군여성 11명을 대상으로 한의사 3인의 망진 평가와 비침습적인 피부 실측 과정(non-invasive skin bio-engineering)을 병행하여 두 그룹 간의 피부 상태를 비교하여 유의한 결과를 얻었기에 이를 보고하는 바이다. 총 17항목의 망진 평가에서는 7개 항목에서 인삼농축크림 장기사용군이 대조군에 비하여 통계적으로 유의하게 우수한 결과를 보였으며 7가지 피부 측정항목에서는 유분, 거칠기, 색소침착 면적과 눈가 주름 깊이에서 인삼농축 크림 장기사용군이 대조군에 비해 우수한 결과를 보였다. 본 실험을 통해 인삼농축크림의 장기사용이 피부에 긍정적인 영향을 줌을 확인하였으며, 또한 한의학적인 진단법과 현대기기를 이용한 피부 계측 방법을 융합하여 한방화장품의 특성을 살린 신규 평가 방법을 제안하고자 하였다. The aim of this study is to evaluate the effect of cosmetic products containing concentrated ginseng using novel methods based on Traditional Korean medicine (TKM). In TKM, inspection of facial skin was an important method to diagnose symptoms and body condition of patients. Doctors in oriental medicine examined a patient as observing symptoms on the face and skin related to inner organs. This was called “mang-jin. In this study, eleven female, who have been using the cosmetic products containing concentrated ginseng for the last 5 years, and eleven healthy controls, who have never used the same product, were recruited. Three doctors in oriental medicine evaluated 17 inspection factors on facial skin. And 7 non-invasive skin bioengineering factors were assessed by various instruments at the same time. In results, 7 factors of the inspection were better in using the product than in controls. And sebum, roughness, pigmentation and wrinkle depth were significantly lower in using the product than in controls. So, this results propose that the cosmetic product containing concentrated ginseng has a good anti-aging effect on skin. And it is suggested that the novel evaluation method combined, Traditional Korean medicine and modern bioengineering technique, has to be developed for holistic concept of Hanbang cosmetics.
