번역활동은 자족적 행위가 아니라 사회의 정치 · 경제 · 문화 등 여러 방면과 관련되어 있다. 번역활동은 사회활동과 현상의 범주 속하지만, 그에 대한 사회학적인 인식과 연구는 오히려 그리 많지 않다. 사회는 번역연구의 출발점이자 종착점이 되어야 한다. 번역활동과 사회환경 간의 관계는 상부상조의 관계다. 사회환경의 도움 없이 번역활동은 시작될 수 없으며, 사회의 발전과 개혁, 문화적 의식의 전환과 신사상의 도입은 모두 번역활동의 조력이 필요하다. 사회적 환경과 수요가 번역활동의 시작 · 전개 및 종료, 역자의 번역 동기 · 목적과 번역방법의 선택이 모두 번역활동에 영향을 준다. 번역활동의 산물인 번역본은 대중매체의 도움 없이 그 사회적 역할을 수행할 수 없으며, 오직 대중매체의 홍보를 통해서만이 그 사회적 기능을 발휘한다. 본고는 오사신문화운동(五四新文化運動) 시기의 사회환경과 번역활동 간의 영향관계를 고찰하며, 동시에 그 시기 번역활동의 사회적 역할을 논의한다. Translation is not a self-sufficient behavior. Conversely, it involves many aspects of society. Although most people attribute translation activities to the category of social activities and social phenomena, there is little social understanding and social studies on translation activities. Society should be the beginning and end of translation studies. The relationship between the translation activities and social environment is complementary. Translation activities are inseparable from the assistance of the social environment, the development and reform of society, Change of cultural consciousness, and the introduction of new ideas all require the assistance of translation activities. Social historical environment and social needs have an impact on the beginning, development and end, translator"s translation motivation, purpose and translation method of translation activities. The product (text) of translation activities is inseparable from the promotion of social mass media. Only through the promotion of mass media can the social function of translation activities be fully reflected. This paper mainly studies the translation activities during the historical period of the May Fourth New Culture, Observe the interaction between the social environment and translation activities during the May 4th New Culture Movement and the social role of translation activities during the May 4th New Culture Movement.

Xin Peng,Bin Wang,Xile Wang,Binbin Ni,Zhaojiang Zuo 한국원예학회 2020 원예과학기술지 Vol.38 No.4

Light quality regulates plant growth and photosynthesis, the drivers of fruit quality, and light quality can be controlled by colored light-quality selective plastic films in field production. To identify the optimal color of plastic film for high-quality strawberry (Fragaria × ananassa) fruit production, plant growth, photosynthetic abilities, and fruit qualities were investigated under transparent (T), red (R), yellow (Y), green (G), blue (B), and purple (P) films. The R film showed the maximum promoting effects on leaf area, petiole length, leaf biomass, and shoot biomass. The R film improved photosynthetic abilities by increasing photosynthetic pigment content, quantum yield (φPo), electron transfer (Ψo and φEo), the density of reaction centers (RC/CSm), and the photosynthetic performance index (PIabs), and by decreasing the dissipation of absorbed solar energy as heat (φDo), while varied reverse effects were detected under other films. For fruit qualities, the R film also improved fruit weight and the content of total sugar, anthocyanin, and soluble protein. Therefore, the R light-quality selective plastic film should be suitable for strawberry production due to the promoting effects on plant growth, photosynthetic abilities, and fruit weight and quality.

Xin-Gui Peng,Zhen Zhao,Di Chang,Yingying Bai,Qiuzhen Xu,Shenghong Ju 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.2

Objective: The purpose of the study was to non-invasively characterize and discriminate brown adipose tissue (BAT) from white adipose tissue (WAT) in rats using spectral computed tomography (CT) with histological validation. Materials and Methods: A lipid-containing phantom (lipid fractions from 0% to 100%) was imaged with spectral CT. An in vivo, non-enhanced spectral CT scan was performed on 24 rats, and fat concentrations of BAT and WAT were measured. The rats were randomized to receive intraperitoneal treatment with norepinephrine (NE) (n = 12) or saline (n = 12). Non-enhanced and enhanced spectral CT scans were performed after treatment to measure the elevation of iodine in BAT and WAT. The BAT/ aorta and WAT/aorta ratios were calculated and compared, after which isolated BAT and WAT samples were subjected to histological and uncoupling protein 1 (UCP1) analyses. Results: The ex-vivo phantom study showed excellent linear fit between measured fat concentration and the known gravimetric reference standard (r2 = 0.996). In vivo, BAT had significantly lower fat concentration than WAT (p < 0.001). Compared to the saline group, the iodine concentration of BAT increased significantly (p < 0.001) after injection of NE, while the iodine concentration of WAT only changed slightly. The BAT/aorta ratio also increased significantly after exposure to NE compared to the saline group (p < 0.001). Histological and UCP1 expression analyses supported the spectral CT imaging results. Conclusion: The study consolidates spectral CT as a new approach for non-invasive imaging of BAT and WAT. Quantitative analyses of BAT and WAT by spectral CT revealed different characteristics and pharmacologic activations in the two types of adipose tissue.

Xin Chen,Linlin Cao,Peng Yan,Peng Wu,Dazhuan Wu 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.11

In this study, the effect of impeller meridional shape on the performance of axial-flow fan is investigated by CFD method. Three axialflow fan impellers with different meridional shapes are designed. The blade angle, blade stacking condition and other structure factors of the impellers are all remained consistent. The performance curves of the three impellers are calculated and compared. In almost all the interested flowrate range, the impeller W3 with an inverted-isosceles-trapezoid meridional shape and the longer blade camber achieves both the higher pressure rise and the higher efficiency than the other two impellers. A two-stage axial-flow fan designed on basis of W3 is manufactured and tested. Test results show good agreement with the calculated performance curves. Further, analyses of the CFD results are conducted to reveal the reasons for the different performance. A newly-defined Local Euler head (LEH) is introduced to represent the distribution of the major Euler work in the axial-flow fan. And the LEH distributions in the three impellers are obtained. W3 achieves the highest LEH at blade Trailing edge (TE), because it could perform the most Euler work to the fluid with the longest blade camber. Then losses in the impellers are analyzed by means of the entropy generation. Among the losses in impeller, the tip leakage loss and endwall friction loss are dominated at design flowrate. The generation condition of the tip leakage loss shows significant differences among the three impellers. And the whole power loss in impeller of W3 is slightly higher than those of the other two models. However, the power loss difference among the three impellers is negligible. And due to the highest shaft power, the efficiency loss of W3 is the lowest of all.

Peng Chen,Ya Peng Li,Can Jin Li,Xin Lei Meng,Bao Zhang,Ming Zhu,Yan-jing Liu,Jing Yuan Wang 한국고분자학회 2013 폴리머 Vol.37 No.3

H-shaped amphiphilic pentablock copolymers (PSt)2-b-PCL-b-PEO-b-PCL-b-(PSt)2 was synthesized via chemoenzymatic method by combining enzyme-catalyzed ring-opening polymerization (eROP) of ε-caprolactone (ε-CL) and atom transfer radical polymerization (ATRP) of styrene. By this process, we obtained copolymers with controlled molecular weight and low polydispersity. The structure and composition of the obtained copolymers were characterized by nuclear magnetic resonance (NMR), gel permeation chromatography (GPC) and infrared spectroscopy analysis (IR). The crystallization behavior of the copolymers was analyzed by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The crystallization behavior of the H-shaped block copolymers demonstrated a PCL dominate crystallization. The self-assembly behavior of the copolymers was investigated in aqueous media. The hydrodynamic diameters of the copolymer micelles in aqueous solution were measured by dynamic light scattering (DLS). The morphology of the copolymer micelles was observed by atomic force microscopy (AFM) and transmission electron microscopy (TEM). The hydrodynamic diameters of spherical micelles declined gradually with the increase of the hydrophobic chain lengths of the copolymers. The critical micelle concentration (CMC) values were determined from fluorescence emission, and it was found that the CMCs decreased with an increase of PSt hydrophobic block lengths.

Peng Song,Yang Hai,Xin Wang,Longhe Zhao,Baoqiang Chen,Peng Cui,Qin-Jian Xie,Lan Yu,Yang Li,Zhengrong Wu,Hong Yu Li 대한약학회 2018 Archives of Pharmacal Research Vol.41 No.4

Realgar (As4S4), as an arsenic sulfide mineraldrug, has a good therapeutic reputation for anticancer inTraditional Chinese Medicine, and has recently beenreported to inhibit angiogenesis in tumor growth. However,considering the poor solubility and low bioavailability ofrealgar, large dose of realgar and long period of treatmentare necessary for achieving the effective blood medicineconcentration. In present study, we resolved the crucialproblem of poor solubility of realgar by using intrinsicbiotransformation in microorganism, and investigatedunderlying mechanisms of realgar transforming solution(RTS) for antiangiogenesis. Our results demonstrated thatRTS had a strong activity to inhibit HUVECs proliferation,migration, invasion, and tube formation. Moreover, RTSinhibited VEGF/bFGF-induced phosphorylation ofVEGFR2 and the downstream protein kinases includingERK, FAK, and Src. In vivo zebrafish and chickenchorioallantoic membrane model experiments showed thatRTS remarkably blocked angiogenesis. Finally, comparedwith the control, administration of 2.50 mg/kg RTSreached more than 50% inhibition against H22 tumorallografts in KM mice, but caused few toxic effects in thehost. The antiangiogenic effect was indicated by CD31immunohistochemical staining and alginate-encapsulatedtumor cell assay. In summary, our findings suggest thatRTS inhibits angiogenesis and may be a potential drugcandidate in anticancer therapy.

The red CaTiO3: Pr3+ phosphors were fabricated by employing a solid-state method using KCl flux, and investigated fortemperature sensing. There were no structural changes observed with increasing KCl concentration, and no impuritieswere detected. The obtained crystal structure was identified as an orthorhombic perovskite, belonging to space group ofPnma(62). The typical sample exhibited spherical particles (1-2 μm). The optical bandgap of the sample was measured to beapproximately 3.62 eV. Notably, when the KCl concentration reached 3%, the sample exhibited the highest photoluminescenceintensity, indicating excellent crystallization strength. They closely resembled the chromaticity coordinates of ideal red lightbased on CIE chromaticity diagram, and the color purity was determined to be 79.51%. Furthermore, the absolute sensitivity(Sa) was approximately as high as 0.148 K-1, while the relative sensitivity (Sr) reached approximately a high value of 6.57% K-1,which highlights the significant potential of optical thermometry.

Xin Peng,Ge Baojun,Tao Dajun,Lv Pin 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.4

To research the variation characteristics and infl uence factors of air gap magnetic fi eld and electromagnetic torque of nuclear power half-speed turbine generator with stator winding inter-turn short circuit, the two-dimensional transient electromagnetic fi eld of generator-external circuit-grid coupling mathematical model is established by fi eld-circuit-network coupling method. Taking the national laboratory’s generator as an example, and comparing the simulation results of the inter-turn short circuit of the armature winding with experimental data, the correctness of the model is validated. On this basis, the simulation model of a 1407MVA nuclear power half-speed turbine generator is built. Then the stator winding inter-turn short circuit fault is simulated when the generator is connected to the grid with rated load. The characteristics of air gap fl ux density and electromagnetic torque are obtained before and after fault, as well as, the relationship between their each component and the fault degree is obtained. At the same time, the variation law of air gap fl ux density and electromagnetic torque is obtained when the relative position between fault winding and magnetic pole changes. The theoretical reference for fault diagnosis and localization using harmonic electromagnetic torque after fault is provided

Chemoenzymatic Synthesis of Dual-responsive Amphiphilic Block Copolymers and Drug Release Studies

Peng Chen,Ya-Peng Li,Shu-Wei Wang,Xin-Lei Meng,Ming Zhu,Jing-Yuan Wang 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.6

Dual-responsive amphiphilic block copolymers were synthesized by combining enzymatic ring-opening polymerization (eROP) of ε-caprolactone (CL) and ATRP of N,N-dimethylamino-2-ethyl methacrylate (DMAEMA). The obtained block copolymers were characterized by gel permeation chromatography (GPC), 1H NMR and FTIR-IR. The critical micelle concentration (CMC) of copolymer was determined by fluorescence spectra, it can be found that with hydrophilic block (PDMAEMA) increasing, CMC value of the polymer sample increased accordingly, and the CMC value was 0.012 mg/mL, 0.025 mg/mL and 0.037 mg/ mL for PCL50-b-PDMAEMA68, PCL50-b-PDMAEMA89, PCL50-b-PDMAEMA112, PCL50-b-PDMAEMA89 was chosen as drug carrier to study in vitro release profile of anti-cancer drug (taxol). The temperature and pH dependence of the values of hydrodynamic diameter (Dh) of micelles, and self-assembly of the resulting block copolymers in water were evaluated by dynamic light scattering (DLS). The result showed that with the temperature increasing and pH decreasing, the Dh decreased. Drug-loaded nanoparticles were fabricated using paclitaxel as model. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) had been explored to study the morphology of the hollow micelles and the nanoparticles, revealing well-dispersed spheres with the average diameters both around 80 nm. In vitro release kinetics of paclitaxel from the nanoparticles was also investigated in different conditions (pH and temperature, etc.), revealing that the drug release was triggered by temperature changes upon the lower critical solution temperature (LCST) at pH 7.4, and at 37 °C by an increase of pH.

Research on the Formation Mechanism of Shear Zone in the Neogene Mudstone Landslide

( Xin Peng ),( Wang Tao ),( Liu Jiamei ),( Liang Changyu ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

The shear zone is the main control factor for the translational and rotational landslides.Different geometric forms of landslides were selected to analyze the process of structural change and the mechanical mechanisms of the bedding-parallel shear zone in Neogen period mudstones. The results show that there are weak layers, with high clay content, in translational landslides and rotational-translational landslides, such as those with bedding-parallel shear zone, while rotational landslides are composed of homogeneous material. The bedding-parallel shear zone can be divided into two parts: the main shear zone and the secondary shear zone. The main shear zone has an S-C fabric, the C plane has a strong scratch, and the S plane develops in high plastic mudstones. The clay contents of the main shear zone in a bedding-parallel sliding zone are greater than 50%, while the absolute content of minerals mixed with illite and montmorillonite exceeds to 20%. Creep and rapid slip are the main forms of structural deformation of the shear zone. Creep deformation mainly develops in the sliding zone with high amounts of clay particles; the microstructural adjustment of the slip zone shows no crack expansion and the clay minerals are a viscous flow. Progressive creep induced by water pressure and gravity will cause the acceleration of the creep and rapid sliding. Rapid sliding deformation, which is due to repeated shear, occurs along the fixed shear fracture-surface.
