( 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.

<P><B>Abstract</B></P> <P>For applications in wearable human-device interfaces and optoelectronics, flexible materials capable of supporting spatial and uninterrupted bandgap tunability are of immense value. We demonstrate theoretically and experimentally the wide bandgap tunability of GaSe nanosheets, with simultaneous PL enhancement, via elastic strain engineering at room temperature. The elastic strain gives rise to a continuously variable electronic band structure profile, with a rate of 40meV/1%, and a 3-fold enhancement in PL intensity is achieved when a uniaxial strain of 1% is introduced. An additional effect is that a new exciton state arises when the strain is raised beyond 0.6%. This work suggests that strain engineering can effectively modulate/control the generation, separation, transport, and recombination of photo-induced charge carriers in GaSe, making it a valuable material for flexible optoelectronic-mechanical applications.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Wide bandgap tunability of GaSe nanosheets, with simultaneous PL enhancement, via elastic strain engineering at room temperature. </LI> <LI> A linear tuning rate of optical band gap of 40 meV/% for uniaxial strain has been achieved, comparable to monolayer MoS2. </LI> <LI> Threefold enhancement in PL intensity achieved with a uniaxial strain of 1%. </LI> <LI> Strain engineering used to control generation, separation, transport, and recombination of photo-induced charge carriers in GaSe. </LI> <LI> New exciton state demonstrated when strain is greater than 0.6%, which shifts in the direction opposite to the main exciton state. </LI> <LI> Suggests route to more efficient capture of optical spectrum, and exciton concentration and trapping by mechanical deformation. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Tong Lin,Huajun Wu,Linlin Luo 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.4

To identify additional genes that are potentially associatedwith deltamethrin toxicology, differentially expressedgene (DGE) libraries of Monochamus alternatus after short-term exposure to a sub-lethal concentration of deltamethrinwere prepared. The transcripts were sequenced using the Illumina sequencing platform. After cleaningand quality checks, the total numbers of clean reads were 7.066 and 7.139 million in the control anddeltamethrin-exposed libraries, respectively. We found that 4886 and 2083 unique genes were significantlyup- and down-regulated, respectively. The gene ontology enrichment analysis identified that 4032, 3379 and8323 DEGs were involved in cellular components, molecular functions and biological processes, respectively,and showed that the genes were distributed among more than 50 categories. The Kyoto Encyclopedia of Genesand Genomes pathway enrichment analysis indicated that the top 20 enriched pathways included the glutathionemetabolismpathway and the antigen processing and presentation pathway. Therewere 42 DEGs enriched inthe antigen processing and presentation pathway, including those encoding the 70-kDa heat shock protein, proteindisulfide isomerase and calreticulin, all ofwhichwere up-regulated. There were 61 DEGs enriched in the glutathionemetabolism pathway, and these included the up-regulated DEGs encoding glutamate–cysteine ligase,glutathione synthase and glutathione reductase and the down-regulated DEGs encoding glutathione Stransferase,glutathione peroxidase and ornithine decarboxylase. This study is the first step toward achievingan understanding of the profile of the secondary targets of deltamethrin in M. alternatus, and the results may provideinsights to further explore the functions of the target genes in detoxification and resistance to deltamethrin.

Convective Heat Transfer Coeicient Model Under Nanoluid Minimum Quantity Lubrication Coupled with Cryogenic Air Grinding Ti–6Al–4V

Jianchao Zhang,Wentao Wu,Changhe Li,Min Yang,Yanbin Zhang,Dongzhou Jia,Yali Hou,Runze Li,Huajun Cao,Hafiz Muhammad Ali 한국정밀공학회 2021 International Journal of Precision Engineering and Vol.8 No.4

Under the threat of serious environmental pollution and resource waste, sustainable development and green manufacturing have gradually become a new development trend. A new environmentally sustainable approach, namely, cryogenic air nanofluid minimum quantity lubrication (CNMQL), is proposed considering the unfavorable lubricating characteristic of cryogenic air (CA) and the deficient cooling performance of minimum quantity lubrication (MQL). However, the heat transfer mechanism of vortex tube cold air fraction by CNMQL remains unclear. The cold air fraction of vortex tubes influences the boiling heat transfer state and cooling heat transfer performance of nanofluids during the grinding process. Thus, a convective heat transfer coefficient model was established based on the theory of boiling heat transfer and conduction, and the numerical simulation of finite difference and temperature field in the grinding zone under different vortex tube cold air fractions was conducted. Simulation results demonstrated that the highest temperature initially declines and then rises with increasing cold air fraction. Afterward, this temperature reaches the lowest peak (192.7 °C) when the cold air fraction is 0.35. Experimental verification was conducted with Ti–6Al–4V to verify the convective heat transfer coefficient model. The results concluded that the low specific grinding energy (66.03 J/mm 3 ), high viscosity (267.8 cP), and large contact angle (54.01°) of nanofluids were obtained when the cold air fraction was 0.35. Meanwhile, the lowest temperature of the grinding zone was obtained (183.9 °C). Furthermore, the experimental results were consistent with the theoretical analysis, thereby verifying the reliability of the simulation model.

Reliability Allocation Method for Remanufactured Machine Tools Based on Fuzzy Evaluation Importance and Failure Influence

Yan-bin Du,Guoao Wu,Ying Tang,Huajun Cao,Shihao Liu 한국정밀공학회 2021 International Journal of Precision Engineering and Vol.8 No.6

Reliability is the key performance indicator for remanufactured machine tools to be approved by customers. Reliability allocation is an important task that needs to be done in the design phase of remanufactured machine tools to ensure that remanufactured products meet the reliability target requirements. A reliability allocation method for remanufactured machine tools is proposed based on fuzzy evaluation importance and failure influence of each component. The importance of each component is evaluated by five indicators such as complexity of structure, maturity of technology, criticality of fault, difficulty of maintenance, and severity of service condition, in which their weights are determined by the method of analytic hierarchy process (AHP). Failure influence is determined by the proportion of downtime caused by each component in total downtime of machine tools. Finally, the proposed method is illustrated in a numerical case study of NC lathe remanufacturing.

Oligonucleotide microarray-based gene expression analysis of pine sawyer (Monochamus alternatus) after treatment with a sublethal dose of diflubenzuron

Chunmei Wei,Linlin Luo,Huajun Wu,Tong Lin 한국응용곤충학회 2013 Journal of Asia-Pacific Entomology Vol.16 No.4

Monochamus alternatus Hope is a serious pest management concern in stands of pines. Diflubenzuron (DFB) is an insect growth inhibitor (IGI), which acts by disrupting chitin formation and deposition, affecting the cuticle and the molting process. As DFB causes a reduction in chitin content, the insect ultimately dies because of abortive molting. In order to understand how M. alternatus reacts toxicologically to DFB, transcriptional profiling of M. alternatus larvae exposed to a sublethal dose of DFB was monitored using a specific 60-mer oligonucleotide microarray derived from a cDNA library. Treatment of M. alternatus with DFB resulted in a total of 364 unique genes varied at least twofold in terms of accumulation. Of these 364 genes, 53 were upregulated, and 311were downregulated. A gene ontology (GO) enrichment analysis revealed that the differentially expressed genes were widely distributed among the molecular function, biological processes, and cellular component categories,reflecting a broad spectrum of the analyzed transcriptome. Genes that play important roles in cuticulogenesis and metabolic detoxification were detected by GOs and pathway enrichment analyses. This study, an attempt to relate new possible biomarkers for assessing secondary effects of DFB on M. alternatus,will assist in DFB future use for controlling M. alternatus and other Lepidoptera insects.

Transcriptome analysis of the Japanese pine sawyer beetle, Monochamus alternatus (Coleoptera: Cerambycidae) by high-throughput Illumina sequencing

Tong Lin,Ziling Cai,Huajun Wu 한국응용곤충학회 2015 Journal of Asia-Pacific Entomology Vol.18 No.3

The Japanese pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a serious pest management concern in pine stands. Although there are currently 1012 expressed tag sequences (ESTs) for M. alternatus deposited in public databases, this number is not sufficient for understanding the molecular biology of this insect. Next-generation sequencing technologies are essential for determining the enormous transcript sequences that are necessary for gene discovery. In the present study, the M. alternatus transcriptome was sequenced using Illumina paired-end sequencing technology. De novo assembling was conducted to generate a collection of 48,787 unigenes (average length 721 bp) that represent the first transcriptome of this species. The majority of the unigenes (78.1%) had top matches (first hit) with sequences from Tribolium castaneum (Herbst). Approximately 57.12% and 42.35% of the unigenes had significant similarities with proteins in the National Center for Biotechnology Information (NCBI) non-redundant protein database (Nr) and Swiss-Prot database, respectively. A total of 9005 (18.46%) unigenes were assigned to Clusters of Orthologous Groups (COG), and 13,484 (27.64%) unigenes were assigned to Gene Ontology (GO) categories. A total of 18,915 unigenes had significant matches in the Kyoto Encyclopedia of Genes and Genomes Pathway database (KEGG) and were assigned to 258 pathways. The unigenes encoding specific genes related to insecticide detoxification and insecticide target enzymes. These results are an invaluable resource for future studies on M. alternatus, especially for studies focused on novel gene discovery and comparative genomics.

Ultra-sensitive graphene based mid-infrared plasmonic bio-chemical sensing using dielectric beads as a medium

Liu, Xiao,Zhang, Duan,Wu, Ye-Cun,Yang, Mei,Wang, Qian,Coileá,in, Cormac Ó,.,Xu, Hongjun,Yang, Chen,Abid, Mohamed,Abid, Mourad,Liu, Huajun,Chun, Byong Sun,Shi, Qingfan,Wu, Han-Chun Elsevier 2017 Carbon Vol.122 No.-

<P>Graphene is moving beyond the realm of simple electronic devices toward areas such as advanced biochemical sensing. The infrared (IR) response of graphene, characterized by collective long-lived charge-carrier oscillations, could be applied in IR-absorption spectroscopy, typically used for bio-chemical analysis. However, direct light absorption by propagating plasmons in graphene is forbidden due to the large momentum mismatch. Proposed methods to overcome this bottleneck come at a cost, the use of noble metal particles on graphene reduces the spectral bandwidth and nano-structuring graphene is expensive. Here, we propose a simple and cheap method to fabricate large scale ultra-sensitive graphene based mid-IR biosensors, by introducing dielectric beads to excite mid-IR range plasmons. Interference from waves scattered by the beads excite surface plasmon polaritons, which propagate several micrometers in graphene and enhance the interaction between the molecules and mid-IR light. This method opens an interesting window for the application of graphene in bio-chemical sensing. (C) 2017 Elsevier Ltd. All rights reserved.</P>

Effects of tryptophan and phenylalanine on tryptophol production in Saccharomyces cerevisiae revealed by transcriptomic and metabolomic analyses

Gong Xiaowei,Luo Huajun,Hong Liu,Wu Jun,Wu Heng,Song Chunxia,Zhao Wei,Han Yi,Dao Ya,Zhang Xia,Zhu Donglai,Luo Yiyong 한국미생물학회 2022 The journal of microbiology Vol.60 No.8

Tryptophol (TOL) is a metabolic derivative of tryptophan (Trp) and shows pleiotropic effects in humans, plants and microbes. In this study, the effect of Trp and phenylalanine (Phe) on TOL production in Saccharomyces cerevisiae was determined, and a systematic interpretation of TOL accumulation was offered by transcriptomic and metabolomic analyses. Trp significantly promoted TOL production, but the output plateaued (231.02−266.31 mg/L) at Trp concentrations ≥ 0.6 g/L. In contrast, Phe reduced the stimulatory effect of Trp, which was strongly dependent on the Phe concentration. An integrated genomic, transcriptomic, and metabolomic analysis revealed that the effect of Trp and Phe on TOL production was mainly related to the transamination and decarboxylation of the Ehrlich pathway. Additionally, other genes, including thiamine regulon genes (this), the allantoin catabolic genes dal1, dal2, dal4, and the transcriptional activator gene aro80, may play important roles. These findings were partly supported by the fact that the thi4 gene was involved in TOL production, as shown by heterologous expression analysis. To the best of our knowledge, this novel biological function of thi4 in S. cerevisiae is reported here for the first time. Overall, our findings provide insights into the mechanism of TOL production, which will contribute to TOL production using metabolic engineering strategies.

Energy Dissipation Characteristics Modelling for Hot Extrusion Forming of Aluminum-Alloy Components

Hongcheng Li,Yuanjie Wu,Huajun Cao,Feng Lu,Congbo Li 한국정밀공학회 2022 International Journal of Precision Engineering and Vol.9 No.6

The hot extrusion forming process is widely used to process aluminum-alloy components in both the automobile and aircraft manufacturing industries. Since it involves pushing the material through the die at increased temperature, it is very energy-intensive despite requiring less blank material allowance. During hot extrusion forming, the multi-stage dynamic conversion of electricity, mechanical energy, and hydraulic energy to heat results in high energy dissipation. In order to improve the power and energy conversion efficiency of hot extrusion forming process, it is necessary to identify the energy dissipation characteristics. The transfer and conversion paths of the electrical, mechanical, and hydraulic energy from the motor to the hydraulic cylinder were firstly depicted based on the motion cycle of the extruder. A bond graph-based energy dissipation model was then proposed for dynamically identifying the energy-saving potentials. The energy dissipation model integrated the power bond graph sub-model of energy conversion elements such as motor, pump, hydraulic valve group, and hydraulic cylinder. These power bond graph sub-models were separately developed to find the energy dissipation state equations of energy conversion elements. An experiment was carried out using data obtained from the energy management system to validate the bond graph-based energy dissipation model. The results have shown that the power and energy conversion efficiency of hot extrusion forming is primarily controlled by the parameters such as extrusion velocity and extrusion force. Both the higher extrusion velocity and lower extrusion force will reduce the power and energy conversion efficiency. An optimal combination of extrusion velocity and pressure can achieve the lowest energy consumption per unit product.
