Namsoo Peter Kim 대한미용의학회 2020 대한미용의학회지 Vol.4 No.1

Background: With the spread of coronavirus disease-19 (COVID-19), face-to-face contact in business and educational hubs has decreased. This is especially true for the beauty industry, where long-term contact with operators and customers is required. Therefore, the emergence of new alternative business models is essential. Objective: The purpose of this study is to apply nonfacing and real-time three-dimensional (3D) nail-printing systems to cosmetic industries, educational institutions, and educational systems. Three-dimensional non-face-to-face printing equipment have enabled nail art to be precisely and remotely controlled, which facilitates the replacement of nail technology that is based on body contact. Methods: From January to April 2020, the use of the internet-of-things (IoT)-controlled non-face-to-face and real-time 3D nailprinting systems was tested. Nail artists and customers were isolated, and more than 200 patterns were tested with non-face-toface contact between Korea and the United States. A built-in IoT operating system was tested in an online platform, and the advantages and problems of non-face-to-face contact were systematically analyzed. Results: The rapid development of IoT-controlled non-face-to-face and real-time 3D nail-printing systems was achieved to reduce entry barriers for nail art utilizing 3D-printing technology. The most crucial parts were determined to be reliably creating 3D shapes, reproducibility, economical operation, and timely maintenance. Conclusion: The nail art business model, in which the education and business sectors depend entirely on face-to-face contact, has been disrupted and deemed unpredictable due to the social distancing norms that have been adopted for countering the COVID-19 epidemic. Nevertheless, secure and remote accessibility to non-face-to-face and real-time 3D nail-printing systems for nail artists were successfully applied and tested to respond to this situation.

Background: With the convergence of internet of things (IoT) and artificial intelligence (AI) technologies with three-dimensional (3D) printing or additive manufacturing, the applications have extended to beauty arts and cosmetics. Objective: The purpose of this research is to confirm the possibility of the convergence of IoT and AI 3D printing technology for cosmetics and beauty art for the 21st century. Methods: From January to October 2019, experienced 3D designers and customers were isolated, and more than 1,000 patterns were verified. Ultraviolet light-emitting diod (UV-LED) technology with built-in patented devices operating on a limited basis was used, and processes using low energies of 3 watts or less were applied. To control the 3D shape of the material, 3D printing technology with the z-axis at a height of 50 microns was applied to the shape to obtain a length of more than 3 cm. Completed products realized via custom design and manufacturing processes were delivered to the customers who installed them on their own. Results: More than 1,000 patterns were successfully printed through Wi-Fi from all over the world for AI-recommended nail art and tattoos. The stability of the IoT has confirmed the quality of 3D printed nails and two-dimensional (2D) tattoos. Moreover, customers are not exposed harmful environments associated with tattoos and 3D nail art. Conclusion: Application of 3D printing technology to the traditional nail art industry allows for the creation of sophisticated and customized shapes in a short period of time with a precision control of less than 50 microns in various colored 3D structures on artificial nail tips. This successful result of the convergence of AI and IoT 3D printing technology in the field of nail art and tattoos is expected to apply further to the fields of cosmetology, makeup, plastic surgery, and art.

Supercritical extraction of decellularized extracellular matrix from porcine adipose tissue as regeneration therapeutics

Seungwon Chung,Hana Kwon,Namsoo Peter Kim 대한미용의학회 2019 대한미용의학회지 Vol.3 No.2

Background: Extracellular matrix (ECM) has been broadly applied and shown great promise in medical applications. ECM products should be used after decellularization and purification. Supercritical carbon dioxide treatment is of particular interest for purifying ECM due to its medical availability and rapid process speed. However, it is not fully researched for treatment of biomaterials for tissue engineering. Therefore, we investigated the optimal conditions of supercritical carbon dioxide processing at different extracting parameters in porcine adipose tissue. Objective: We aimed to identify the optimal supercritical extracting conditions to produce non-cytotoxic and sterile decellularized extracellular matrix (DE-ECM) for regeneration therapeutics. Methods: The three-day dual treatment including enzymatic decellularization and supercritical fluid extraction of pork adipose tissue was performed. Two protocols using different extracting parameters were applied to evaluate the influence of extracting pressure and temperature on the extraction yield, DNA concentration, and remaining collagen in product. Results: Yield rate increased when high temperature or pressure was applied and pre-enzyme treatment had higher yield rate percent than pre-supercritical processing. Nearly 90% DNA was removed from the pre-enzyme sample when extracted at 3.04×10 7 Pa and 30°C±5°C. The pre-enzyme process had efficient extracting ability at each temperature and pressure and the remaining collagen steadily decreased with increase in extracting pressure and temperature. At the lowest temperature (20°C±5°C) and pressure (1.01×10 7 Pa), remaining collagen was 75.74%±1.83%. Supercritical extraction technology can produce DE-ECM eliminating DNA content efficiently and the remaining proper collagen amount successfully. Conclusion: This study evaluated the feasibility of utilizing supercritical extraction technology in bio-materials and was proven to be is successful. Through controlling the extracting pressure and temperature, this technology has a potential for DE-ECM mass production, which can be useful as tissue regeneration therapeutics as well new drug delivery paradigm.

Lee Jisu,Aditya Abhilash,Kim Jihye,Kim Namsoo Peter 대한미용의학회 2021 대한미용의학회지 Vol.5 No.1

Background: The emphasis on non-face-to-face or untact operation services is on the rise due to the ongoing widespread of COVID-19 epidemics, which have caused severe damage worldwide. Untact technology has been applied not only to everyday life but also to the beauty art industry that relies on customer service with contact. Objective: A safe non-permanent tattoo ink is necessary to overcome the stigma of permanent tattoos and tattoo removal procedures. The purpose of this study is to efficiently deliver non-permanent tattoo ink into the skin through sophisticated untact printing techniques and safe silver compound ink, further minimizing the side effects due to unsanitary conditions. Methods: Silver-gelatin compound ink serves as an excellent alternative for conventional permanent tattoos with additives. Pistontype extruder (PTE) system and internet of things (IoT) integrated precision-controlled non-permanent and untact system using silver nanoparticle ink. Results: Complex and sophisticated designs were three-dimensional (3D) printed using a non-permanent tattoo ink containing an optimum concentration of Ag+ under 5 N compression force through a 100 μm radius nozzle and diffused up to 200 μm into the stratum corneum through skin contact. Intradermal diffusion simulation and disappearance of the ink within two weeks of the human skin replacement cycle were successfully demonstrated. Conclusion: The integration of IoT and 3D printers has enabled a hygienic untact tattoo printing technique that has been verified through repeated testing. This study could arouse positive possibilities and interests in the rapidly changing beauty art fields. It provides a new tattoo methodology and further research ideas for the 3D printing applications in tattoo production.

양다은,손현진,배창진,김정효,강길순,구자룡,Namsoo Peter Kim 한국미술교육학회 2022 美術敎育論叢 Vol.36 No.2

비대면 교육이 보편화되면서 기술과 예술의 상호보완을 위한 전통적인 세라믹 기술 내 혁신의 필요성이 제기되었다. 3D 프린팅의 원격 정밀 제어가 가능한 고점도의 세라믹 프린팅 기술은 비조 디자인을 활용하여 미적으로 높은 수준의 표면 윤곽을 구축하는 것을 가능하게 했다. 이러한 비조 디자인은 제품의 희귀성과 창의성을 훼손하지 않고 발전하여 10년 이상의 검증을 통해 교육시장에 성공적으로 적용되었다. 한편 디지털 제조(DM)는 낮은 인건비와 저렴한 자재 공급에 기반한 대량 생산 개념에서 벗어나 맞춤형 디자인을 생산 현장에 디지털로 전송할 수 있는 틈새시장을 형성했다. 예술 분야 안에서 디지털 제조는 예술가들이 자유롭게 창작 활동을 할 수 있도록 돕는 새로운 분야로 자리매김했으며 공학과 예술의 학제 간 교육은 각각이 추구하는 궁극적인 목표의 차이를 최소화하였다. 비조 기법은 IoT가 적용된 장비와 그에 적합한 재료를 이용한 교육 프로그램에 적용되어, 최종적인 열처리 과정을 통해 창의적인 디자인과 개인의 감정이 구현된 작품들을 탄생시켰다. 비조 3D 프린팅 플랫폼은 2022년 2월부터 5주 동안 도예 분야에 30년 이상 경험이 있는 전문가들과 협업을 위해 마련되어 김해 분청도자박물관에 설치되었다. 총 20시간의 비조 교육 프로그램은 모든 참여자들이 자신만의 창의적인 3D 비조 작품을 성공적으로 제작하는 것을 통해 참여자들의 창의성과 예술적 잠재력을 이끌어냈다는 점에서 교육적 의미가 있다.
