본 논문의 목적은 코로나-19 이후 뮤지엄 운영이 차질을 빚고 있는 상황에서 발달하고 있는 VR 전시의 한계에 대해 논의하고, 그 대안으로 현재까지 소개된 여러 유형의 AR 전시를 뮤지엄 중심으로 연구하여 코로나 시대에 디지털 콘텐츠가 어떻게 효과적으로 변화하고 활용될 수 있는지 알아보는 데 있다. VR/AR 전시를 코로나-19를 전후로 살펴본 결과, VR은 대부분 현실을 동영상으로 촬영하여 소개하고 있어 미학적 현장감부재와 HMD 장비운영 문제를 드러낸다. 주로 보급률이 높은 모바일을 이용한 AR은 특정 실내 공간에서 콘텐츠를 감상할 수 있는 '뮤지엄용', 개방된 실외 공간에서 이용할 수 있는 '특정 장소형', 디지털 콘텐츠와 인쇄물에 접목하여 우편형식으로 발송 가능한 '불특정 장소형'으로 나누어 볼 수 있다. 이중 특정/불특정 장소형은 실외 공간 및 우편 발송을 통해 가장 높은 비대면 효과를 나타내고 있어 펜데믹 시대의 효율적인 뮤지엄 콘텐츠 개발 방향을 제시할 수 있다.

1895년 뤼미에르 형제에 의해 탄생한 영화는 최초의 것이 아니었다. 4년 전 영화 촬영기를 발명한 에디슨이 이미 수십 편이 넘는 영화를 만들고 있었기 때문이다. 이런 에디슨 영화는 상대적으로 저 평가되어왔다. 그것은 영화를 보여주는 플랫폼이 키네토스코프란 일인용 뷰어를 통한 방식이었기 때문이다. 그러나 영화 자체의 물리적인 특성은 현대영화와 동일하며 오히려 다른 초기영화들에 비해 독특한 미학적 차별성을 가지고 있다. 주제가 연예 오락 지향적이며 영상은 인위적 콘트라스트 특징을 가지고 있다. 또한 영화 탄생 이전의 작품임에도 허구 영화가 추구하는 중요 창작요소들과 장르를 선보이고 있으며 산업수준의 제작 시스템과 전문가들을 갖추고 있었다. 뤼미에르의 영화가 사실을 그려낸 다큐멘터리 영화의 시작이라면 에디슨 영화는 현대영화의 특징인 흥행을 추구하는 대중영화의 시작으로 사적(史的) 가치를 부여할만하다.

Wounds that heal with excessive scar formation result in poor functional and aesthetic outcomes. To address this, in our study, visible light cured glycol chitosan (GCH) hydrogels containing endothelial growth factor (EGF) and basic fibroblast growth factor (bFGF) were prepared (GCH-EGF, GCH-FGF and GCH-EGF/FGF) and evaluated their efficacies on the improvement of wound healing in vivo. In vitro release test showed that the growth factors were released in a sustained manner along with initial burst for 24 h. In vitro cell proliferation assay of L-929 mouse fibroblast cell line resulted in the superior ability of GCH-EGF/FGF on the rate. In vivo results demonstrated that the growth factor loaded GCHs further enhanced wound healing compared with GCH. In particular, GCH-EGF/EFG showed the most remarkable wound healing effect among the samples.

Background In breast reconstruction, synthetic meshes are frequently used to replace acellular dermal matrix (ADM), since ADM is expensive and often leads to complications. However, there is limited evidence that compares the types of substitutes. This study aimed to compare complications between materials via a network meta-analysis. Methods We systematically reviewed studies reporting any type of complication from 2010 to 2021. The primary outcomes were the proportion of infection, seroma, major complications, or contracture. We classified the intervention into four categories: ADM, absorbable mesh, nonabsorbable mesh, and nothing used. We then performed a network meta-analysis between these categories and estimated the odds ratio with random-effect models. Results Of 603 searched studies through the PubMed, MEDLINE, and Embase databases, following their review by two independent reviewers, 61 studies were included for full-text reading, of which 17 studies were finally included. There was a low risk of bias in the included studies, but only an indirect comparison between absorbable and non-absorbable mesh was possible. Infection was more frequent in ADM but not in the two synthetic mesh groups, namely the absorbable or nonabsorbable types, compared with the nonmesh group. The proportion of seroma in the synthetic mesh group was lower (odds ratio was 0.2 for the absorbable and 0.1 for the nonabsorbable mesh group) than in the ADM group. Proportions of major complications and contractures did not significantly differ between groups. Conclusion Compared with ADM, synthetic meshes have low infection and seroma rates. However, more studies concerning aesthetic outcomes and direct comparisons are needed.

Expanding the supply of BIPV is crucial to strengthening the competitiveness of the photovoltaic industry and achieving Nationally Determined Contributions through the zero-energy building mandatory policy. BIPV is a technology that integrates into the building envelope to generate electricity and provide functions as a building material. It is suitable for domestic environments with many high-rise buildings due to the narrow land area and urbanization. To expand the supply of BIPV, economics, safety, and aesthetics must be ensured. In this study, a color BIPV module with a color PET film applied as a front material was manufactured for aesthetic and economic feasibility. The relationship between power output and transmittance according to color was analyzed. By analyzing the power output of the module and the transmittance of the film, the wavelength band (transmittance reduction band) that has the greatest effect on efficiency was analyzed regarding the color of the film. The red film showed the narrowest transmittance reduction band and the lowest degree of decrease in transmittance, making it ideal for minimizing the efficiency decrease rate compared to existing ones.

Blood circulation is one of the most important life support functions of our body. It is essential to maintain healthy blood circulation as problems with blood circulation can lead to numerous diseases and serious complications. This study developed women's leggings with gradual compression and soft surface heating functions to improve blood circulation, and evaluated their performance and wearability. A silicon print pattern was developed to provide gradual compression, and a flexible heating surface coated with MWCNT (multi-walled carbon nanotube) conductive ink was fabricated for comfort and thermal effect. For the design, incision lines and materials were applied in consideration of aesthetic aspects, and design lines and colors were altered using a 3D program. The developed leggings showed that blood circulation can be improved when gradual compression and heating functions are simultaneously applied. Results were confirmed through measurements of clothing pressure, blood flow, and surface temperature. In the subjective wearability evaluation, it was confirmed that wearers felt gradual pressure, and they showed high satisfaction with wearability and design.
