중국 패션사진에 나타난 전통요소 활용에 관한 연구

동서원(Tong Shi Yuan),이상은(Sang Eun Lee),양종훈(Jong Hoon Yang) 한국콘텐츠학회 2018 한국콘텐츠학회논문지 Vol.18 No.3

최근 중국에서 중국풍(中國風)이라는 예술 형식을 적용한 창작이 늘어나고 있다. 중국풍이란 중국적 요소를 현대적 감각으로 표현하는 하나의 예술 양식으로 이해할 수 있다. 본 논문은 중국의 전통요소를 패션사진에 효과적으로 구현하는 방식을 탐구하기 위해서 중국의 대표적인 패션사진가 첸만을 중점적으로 분석했다. 연구 결과 첸만은 중국적 요소들의 전형적인 이미지를 반복적으로 활용하는 방식을 지양하고 전통요소들이 갖는 상징적인 의미를 현대적인 이미지로 시각화했다. 이러한 작업으로 첸만은 패션사진 속 상품 및 브랜드의 이미지를 효과적으로 전달할 수 있었으며 더 나아가 중국 패션의 정체성을 알려 상업적, 예술적 가능성을 인정받을 수 있었다. 본 연구는 중국풍 패선사진가들이 전통을 답습하지 않고 중국 전통요소를 현대적으로 재해석하는데 새로운 방향을 제시한다. In recent years, a number of Chinese artists are interested in ‘Chinese-style’. ‘Chinese-style’ can be understood as an art form in which Chinese elements are combined with modernized sensibilities. This paper analyzed how Chinese traditional elements can be effectively implemented in fashion photography, focusing on Chen Man, a leading fashion photographer in China. Our research shows that Chen Man looks to the traditions and history of China to inspire her modern work, which makes her unique as a Chinese fashion photographer. She tried not to repetitively express typical images of Chinese elements but to visualize the symbolic meaning of traditional elements as new images of modern China. Through this practice, she were able to effectively communicate the images of products and brands promoted in fashion photos. Furthermore, her works are being recognized by not only the fashion industry but also the international art elite as they contribute to building and promoting Chinese fashion identity. Research on Chen Mans work is significant in providing a new way for ‘Chinese-style’ fashion photographers to reinterpret Chinese traditional elements without following Chinese tradition.

Fishbone Oscillations in the Experimental Advanced Superconductivity Tokamak

A fishbone oscillation was observed in the neutral beam injection plasma at Experimental Ad- vanced Superconductivity Tokamak (EAST). This m = 1/n = 1 (m, n: poloidal, toroidal mode numbers, respectively) typical internal kink mode travels in the ion-diamagnetism direction in the poloidal section with a rotation speed close to the ion diamagnetic drift frequency. A high thermal plasma beta and high amounts of energetic ions are necessary for the mode to develop. Fishbone oscillations can expel heavy impurities in the core, which favors sustaining a high-performance plasma. The born frequency of the fishbone oscillation is the ion diamagnetic drift frequency and the chirping down of the frequency during the initial growth phase is the result of a drop in ion- diamagnetic drift frequency. The excitation energy is thought to be due to the thermal plasma pressure gradient; however, the development of a fishbone oscillation is related to energetic ions.

Background: Shufeng Jiedu capsule has been widely used in China for acute upper respiratory tract infections (AURTIs). The aim of this study was to evaluate its effectiveness and safety for AURTIs. Methods: Randomized controlled trials comparing SFJD with conventional drug for patients with AURTIs were included. Eight databases were searched from their inceptions to February 2021. Data was synthesized using risk ration (RR) or mean difference (MD) with their 95% confidence interval (CI). The primary outcome was resolution time of typical symptoms. Results: Twenty-five RCTs involving 3410 patients were included. SFJD in combination with conventional drug was associated with; in common cold shortening the duration of fever (MD −1.54 days, 95% CI [−2.15,−0.92], I2 = 80%, n = 385, 3 trials) and cough (MD −1.22 days, 95% CI [−1.52, −0.93]); in herpangina, shortening the duration of fever (MD -0.68 days, 95% CI [−1.15, −0.21], I2 = 68%, n = 140, 2 trials) and blistering (MD −0.99 days, 95% CI [−1.23, −0.76], n = 386, 3 trials); in acute tonsillitis and acute pharyngitis shortening the duration of fever (MD −1.13 days, 95% CI [−1.36, −0.90], I2 = 33%, n = 688, 7 trials) and sore throat (MD −1.13 days, 95% CI [−1.40, −0.86], I2 = 84.1%, n = 1194, 10 trials). SFJD also improving their cure rate with a range (1–5 days). No serious adverse events were reported. Conclusion: Low certainty evidence suggests that SFJD appears to shorten the duration of symptoms in AURTIs, improve cure rate and seems safe for application. However, high quality placebo controlled trials are warranted to confirm its benefit.

Protection Against Helicobacter pylori Infection by a Trivalent Fusion Vaccine Based on a Fragment of Urease B-UreB414

Li Wang,Xiao-Fei Liu,Shi Yun,Xiao-Peng Yuan,Xu-Hu Mao,Chao Wu,Wei-Jun Zhang,Kai-Yun Liu,Gang Guo,Dong-Shui Lu,Wen-De Tong,Ai-Dong Wen,Quan-Ming Zou 한국미생물학회 2010 The journal of microbiology Vol.48 No.2

A multivalent fusion vaccine is a promising option for protection against Helicobacter pylori infection. In this study, UreB414 was identified as an antigenic fragment of urease B subunit (UreB) and it induced an antibody inhibiting urease activity. Immunization with UreB414 partially protected mice from H. pylori infection. Furthermore, a trivalent fusion vaccine was constructed by genetically linking heat shock protein A (HspA), H. pylori adhesin A (HpaA), and UreB414, resulting in recombinant HspA-HpaA-UreB414 (rHHU). Its protective effect against H. pylori infection was tested in BALB/c mice. Oral administration of rHHU significantly protected mice from H. pylori infection, which was associated with H. pylori-specific antibody production and Th1/Th2-type immune responses. The results show that a trivalent fusion vaccine efficiently combats H. pylori infection, and that an antigenic fragment of the protein can be used instead of the whole protein to construct a multivalent vaccine.

Self-assembly and Mechanism of L-Alanine-based Dihydrazide Derivative as Excellent Gelator of Organic Solvents

Wang, Chuan-Sheng,Wang, Xiao-Hong,Li, Zhi-Yuan,Wei, Wei,Shi, Zhong-Liang,Sui, Zhi-Tong Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.4

A new organogelator, L-Alanine dihydrazide derivative can self-assemble in various organic solvents and turned them into thermally reversible physical supramolecular organogels at extremely low concentrations (< 2 wt %). The gel-sol phase transition temperatures ($T_{GS}$) were determined as a function of gelator concentration and the corresponding enthalpies (${\Delta}H_g$) were extracted. Scanning electron microscopy (SEM) measurements revealed that the interspaces of fiber-like network structures were diminished with the increasing of the LMOG concentration. FT-IR spectroscopy studies revealed that hydrogen-bonding and hydrophobic interaction were the driving forces for the formation of the gels. Based on the data of XRD and molecular modeling, the possible packing modes for the formation of organogelator aggregates were proposed.
