Zhaoshan Wu,Liya Zhou,Xuemei Ding,Xiongying Wu,Laili Wang 한국의류학회 2022 Fashion and Textiles Vol.9 No.1

Practices in the textile and apparel industry (TAI) have led to numerous environmental and social problems, which have prompted extensive research on the sustainable development of the textile and apparel industry (SDTAI). This paper presents a comprehensive and quantitative analysis of the status quo in the SDTAI domain using scientometrics. From 1987 to 2019, the Web of Science core collection databases (SCI and SSCI) included 863 journal articles related to SDTAI, and our analysis results were as follows: (1) 60 critical research keywords occur in the knowledge base; (2) four research hotspots were identifed; (3) fve themes constituted the main knowledge area; and (4) based on the knowledge base, research hotspot, and knowledge domain, the knowledge structure consisted of nine subjects and fve systems. This paper proposes a knowledge roadmap that can be helpful for practitioners and academicians to better understand the current sustainable development status and trends in the TAI.

중국 국유기업 지배구조를 통한 사회적 책임 수행의 입법경험

( Wu-huajun ),( Nan-xuemei ) 연세법학회 2023 연세법학 Vol.41 No.-

기업 사회적 책임의 입법규정은 경제발전 방식에 부합하여야 할 뿐만 아니라 지배구조에 의하여 현실화 될 수 있다. 중국 회사법 개정안에서 기업 사회적 책임에 대한 규정을 살펴보면, 기존의 합법적 경영 이념을 강조하는 사회적 책임 규정으로부터 점차적으로 사회이익과 환경이익 및 근로자 이익을 함께 추구하는 사회적 책임의 입법 규정으로 전환되었다. 본 문은 중국의 경제에서 국유기 업발전이 차지하는 특수성을 감안하여, 현재 중국에서 일어나고 있는 국유기업의 지배구조를 통한 기업 사회적 책임을 부각하려는 입법적인 움직임을 토대로, 기업 사회적 책임에 대한 지배구조 차원의 입법 경험과 중국 회사법 개정안의 내용을 살펴보았다. The content of corporate social responsibility must not only conform to the mode of economic development, but also can be realized by the corporate governance structure. Looking at the provisions on social responsibility in the revision of China's company law, the existing social responsibility provisions that emphasize legal management ideology are gradually revised to the corporate social responsibility provisions that pursue the interests of society, environment, and worker. Considering the peculiarity of China enterprises’ development in China’s economy, this paper examined the contents of corporate social responsibility in the revision of China’s company law on the basis of the legislative initiatives that highlight corporate social responsibility through the governance structure of state-owned companies in China.

Jiang Wu,Xian Li,Jian-Xing Ren,Xuemei Qi,Ping He,Bu Ni,Chong Zhang,Chengzhen Hu,Jun Zhou 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.32 No.-

TiO2 hollow sphere was synthesized by hydrothermal method using trifluoroacetic acid (TFA) andTi(SO4)2 as raw materials, and it was applied to photocatalytic oxidization of elemental mercury (Hg0) inthe simulated flue gas. The prepared samples were well characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectronspectroscopy (XPS), UV–vis diffuse reflectance spectra (UV-vis DRS) and nitrogen adsorption/desorption. The results showed that only anatase phase TiO2 hollow sphere was obtained. The average diameter ofTiO2 hollow spheres was about 800 nm and the shell thickness was about 200–400 nm. When M, themolar ratio of TFA to Ti(SO4)2, was higher than a certain value, the photocatalytic activity of preparedTiO2 hollow spheres began to reduce. When M = 2, addition TFA content was the best quantity, which gotthe best TiO2 hollow spheres and provided the most appropriate F decomposed from TFA during thesample preparation, which was helpful to its photocatalytic ability. In the experimental temperaturerange, the photocatalytic oxidation efficiency decreased with the increasing of reaction temperature, andthe intensity of UV irradiation had an important effect on the photocatalytic reaction. When UVirradiation intensity was 303.45 mW cm 2 and reaction temperature was 55 8C, TiO2 hollow spheresample prepared at M = 2 had the highest photocatalytic ability and the mercury removal efficiencyreached up to 82.75%.

Chong Wu,Xuemei Yang,Lijuan Feng,Fei Wang,Haixia Tang,Yanlei Yin 한국원예학회 2019 Horticulture, Environment, and Biotechnology Vol.60 No.5

This study aimed to explore leaf-color associated genes in Gleditsia sinensis ( G. sinensis ) using bioinformatics methods. Green, purple, and yellow leaves were collected from G. sinensis in Shandong Institute of Pomology. Total RNA was collectedfrom leaves and subjected to transcriptome sequencing. Diff erentially expressed genes (DEGs) were identifi ed amongthe diff erent colored leaves using RSEM method followed by functional enrichment analysis. Finally, qRT-PCR analysis wasused to assess the expression of several pigment-related genes enriched in signifi cant GO or KEGG terms. A total of 10,953,14,961, and 8916 DEGs were identifi ed between green vs. purple leaves, green vs. yellow leaves, and purple vs. yellow leaves,respectively. Among the green vs. purple leaves, DEGs were signifi cantly enriched in terms of iron ion binding, tetrapyrrolebinding, (e.g., CYP26A1 , CYP97A3 , and CYP86A1 ), and starch and sucrose metabolism (e.g., TPS and VTC2 ). DEGsfor green/purple vs. yellow groups were markedly enriched in circadian rhythm-plant KEGG pathway, including ELF3 andCHS . Compared with their expression in green leaves, CYP26A1 , CYP97A3 , CYP86A1 , TPS and VTC2 were signifi cantlydownregulated in purple leaves, while downregulation of ELF3 and upregulation of CHS was detected in yellow leaves. CYPs (e.g., CYP26A1 and CYP97A3 ) might play critical roles in the determination of leaf color in G. sinensis via iron ionand tetrapyrrole binding. In addition, genes related to starch and sucrose metabolism (e.g., TPS and VTC2 ), and circadianrhythms (e.g., ELF3 and CHS ) might also be involved in controlling leaf color.

Zhang, Xuemei,Wang, Liqin,Wu, Yangsheng,Li, Wenrong,An, Jing,Zhang, Fuchun,Liu, Mingjun Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.10

Myostatin (MSTN) can negatively regulate the growth and development of skeletal muscle, and natural mutations can cause "double-muscling" trait in animals. In order to block the inhibiting effect of MSTN on muscle growth, we transferred zinc-finger nucleases (ZFN) which targeted sheep MSTN gene into cultured fibroblasts. Gene targeted colonies were isolated from transfected fibroblasts by serial dilution culture and screened by sequencing. Two colonies were identified with mono-allele mutation and one colony with bi-allelic deletion. Further, we introduced the MSTN-ZFN mRNA into sheep embryos by microinjection. Thirteen of thirty-seven parthenogenetic embryos were targeted by ZFN, with the efficiency of 35%. Our work established the technical foundation for generation of MSTN gene editing sheep by somatic cloning and microinjection ZFN into embryos.

Background: Binafuxi granules are a traditional Uighur medicine (TUM) for treating the common cold with fever. However, high-quality clinical studies supporting its efficacy and safety are lacking. Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase II clinical trial, patients with common cold and fever were randomly assigned to a high-dose group, low-dose group, and placebo group in a 1:1:1 ratio. Outcomes were time to fever relief, time to fever clearance, proportion of afebrile patients, time to symptom disappearance, rate of symptom disappearance, effective rate, emergency drug usage and safety assessment. Results: A total of 235 patients were recruited. Of these, 234 were included in the full analysis set (FAS), and 217 were included in the per-protocol set (PPS). In the FAS analysis, the median time to fever relief was 6.00 h, 5.54 h and 10.65 h (P = 0.31) in the high-dose group, low-dose group and placebo group, respectively. The median time to fever clearance was 18.29 h, 20.08 h and 25.00 h (P = 0.0018), respectively, and the proportion of afebrile patients was 92.4%, 89.7% and 71.4% (P = 0.0002), respectively. There was a significant difference in the disappearance time and disappearance rate of all symptoms and of individual symptoms. No serious adverse events were found. Conclusions: Binafuxi granules can dose-dependently shorten the fever course and improve clinical symptoms in patients suffering from the common cold with fever.

Yongshan Ma,Xuemei Li,Xiaofeng Wei,Tianyi Jiang,Junsen Wu,Huixue Ren 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.7

We prepared amino acid functionalized water-soluble perylene diimides: N,N'-bi(L-glutamic acid)-perylene- 3,4;9,10-dicarboxylic diimide (1), N,N'-bi(L-phenylalanine acid)-perylene-3,4;9,10-dicarboxylic diimide (2), N,N'-bi(Lglutamic amine)-perylene-3,4;9,10-dicarboxylic diimide (3) and N,N'-bi(L-phenylalanine amine)-perylene-3,4;9,10- dicarboxylic diimide (4). The structures of 3 and 4 were confirmed by 1H NMR, FT-IR and MS. The maximal absorption bands of compound 1 and 2 in concentrated sulfuric acid were red-shifted for about 48 and 74 nm, respectively, compared with that of Perylene-3,4,9,10-tetracarboxylic acid dianhydride (PTCDA). Nearly no fluorescence was observed for compounds 1 and 2 in water, while compounds 3 and 4 were significantly water-soluble and had very high fluorescent quantum. The mechanism of the optical properties change was discussed, and the π-π stacking caused by H+ led to the changes of fluorescence spectrum and absorption spectrum. The calculated molecular orbital energies and the frontier molecular orbital maps of compounds 1-2 based on density function theory (DFT) calculations were reported. Owing to the high water-soluble, the perylene derivatives 3 and 4 were successfully applied as high-performance fluorochromes for living hela cells imaging.

Wei Jin,Xuemei Shi,Fei Ge,Wei Zhang,Hongbin Wu,Chengyuan Zhong 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.2

In this paper, we study the various impacts of connecting distributed generation (DG) to the distribution network. The comprehensive evaluation index system (CEIS) of four hierarchies is established, considering economy, reliability and voltage quality, and the calculation methods of different indexes are presented. This paper puts forward an improved triangular fuzzy number analytic hierarchy process (ITFNAHP) to weight the second level indexes (SLI) and the third level indexes (TLI), and calculates the variation coefficient to weight the fourth level indexes (FLI). We calculate the comprehensive weight coefficients based on the weight coefficients of the SLI, TLI and FLI, and then calculate the comprehensive evaluation of satisfaction (CES) of different access schemes. On the basis of the IEEE 33-bus example system, simulations of the calculation methods and the comprehensive evaluation method are carried out under different DG access schemes according to the same total investment cost and the same permeability, respectively, and the simulation results are analyzed and discussed.

Chen, Jing,Wu, Xuemei,Jin, Zongming,Yao, Weiguo The Korean Vacuum Society 1998 Applied Science and Convergence Technology Vol.7 No.1

Ge quantum dots in $SiO_2$ thin films were prepared by r.f. magnetron co-sputtering using a Ge, $SiO_2$ composite target. The size of quantum dots was modulated by controlling of substrate temperature during depositing and annealing of samples deposited at certain substrate temperature. A series of work was done on the influence of preparing parameters on the growth of quantum dots, and a discussion on the formation and growth of quantum dots under different preparation parameters is given.

Study on suppression mechanism of electron emission from Mo grid coated with carbon film by dual ion beam deposition

Lu Yuehui,Wu Xuemei,Liu Xianghuai,Zhuge Lanjian 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.3

It is problematic that electrons are emitted from the Mo grid of pulsed-controlled grid traveling wave tubes, caused by the contamination of cathode evaporation material, i.e. BaO. Some studies show that a Mo grid coated with carbon can greatly suppress grid electron emission. However, the reason for the electron emission suppression is not completely clear. To understand the mechanism of electron emission suppression of a BaO/C/Mo system, carbon lms were prepared on Mo substrates at room temperature by means of DIBSD (dual ion beam sputtering deposition), and BaO layers were coated by using a chemical method. Post-annealing was conducted under a owing nitrogen ambient at 700 C for 1.5 hours. The structure of the as-deposited carbon lms was evaluated by TEM, AES and Raman spectroscopy. The annealed samples, the BaO/ Mo and BaO/C/Mo systems, were analyzed by XPS. The results suggest that the chemical reaction between BaO and C at high temperature eliminates the concentrations of Ba or BaO on the surface of the C/Mo system. It can be believed that the high work function material used as the grid surface coating and elimination of BaO on its surface have a critical eect on grid electron emission suppression. Moreover, the carbon lm was characterized by density, homogeneity and high adhesion, owing to the features of DIBSD.
