Yu-Hong TSOU,Yung-Fu HUANG,Su-Chuan LIU,Manh-Hoang DO 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.4

This article systematically reviews the adoption of total quality management (TQM) implementation and corporate social responsibility (CSR) initiatives on firm performance. A total of 233 published documents from 1996 to 2020 in international journals have been collected and listed on the SCOPUS database. It aims to fill the existing literature gap regarding TQM and CSR practices and point out a future research agenda. This study employed a systematic literature review approach to review those manuscripts related to TQM, CSR topics focused on firm performance. Consequently, the results stressed that TQM and CSR are excellent tools and have a similarity to support the firms to attain corporate sustainability; however, TQM practices have given more interest than CSR initiatives. Moreover, the results highlighted that only a few articles are interested in simultaneously combining TQM and CSR initiatives although this idea is rising in recent years. Thus, the statistical findings indicated several research gaps that remain unaddressed. It is worthy of considering TQM and CSR integration; however, other scholars need to identify the critical success factors that could enable TQM practices or barriers to CSR adoption. Particularly spending more attention on the transitional economies context, which is considering a promising future research context.

Qi Wen-Chuan,Fu Hong-Juan,Sun Rui-Rui,Li Xiang,Cai Ding-Jun,Wang Chao,Liang Fan-Rong 한국한의학연구원 2022 Integrative Medicine Research Vol.11 No.3

Background: The number of systematic reviews or meta-analyses (SRs/MAs) on the effectiveness of acupuncture for angina pectoris (AP) is increasing. Due to the inconsistent conclusions and unknown quality of these SRs/MAs, this overview aimed to systematically evaluate and synthesize the existing SRs/MAs, attempting to provide more reliable evidence for the effectiveness and safety of acupuncture in the treatment of AP. Methods: SRs/MAs were searched via eight databases from inception to March 14, 2022. The risk of bias was evaluated using the Risk of Bias in Systematic reviews (ROBIS) tool. The quality of the methodology, reporting, and evidence were assessed by the Assess Systematic Reviews 2 (AMSTAR-2), the Preferred Reporting Item for Systematic Review and Meta-analysis for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system, respectively. Results: Sixteen SRs/MAs were included and fifteen SRs/MAs were considered being of critically low quality according to AMSTAR-2. Only three SRs/MAs were rated at low risk of bias. No study reported all the items listed in the PRISMA-A checklist. No high-quality evidence with GRADE assessment was found. With the low-quality evidence, acupuncture combined with other interventions was superior to monotherapy (medications or Chinese medicine) in the angina symptom and electrocardiogram recovery. No adverse effects owing to acupuncture were reported. Conclusions: Owing to the lack of high-quality evidence provided by the current SRs/MAs, the effective-ness of acupuncture for AP still warrants further proof. Further researches with more critical design and methodology are needed for providing more convincing evidence.

Metabolism of an Insecticide Fenitrothion by <i>Cunninghamella elegans</i> ATCC36112

Zhu, Yong-Zhe,Fu, Min,Jeong, In-Hong,Kim, Jeong-Han,Zhang, Chuan-Jie American Chemical Society 2017 Journal of agricultural and food chemistry Vol.65 No.49

<P>In this study, the detailed metabolic pathways of fenitrothion (FNT), an organophosphorus insecticide by <I>Cunninghamella elegans</I>, were investigated. Approximately 81% of FNT was degraded within 5 days after treatment with concomitant accumulation of four metabolites (M1–M4). The four metabolites were separated by high-performance liquid chromatography, and their structures were identified by mass spectroscopy and/or nuclear magnetic resonance. M3 is confirmed to be an initial precursor of others and identified as fenitrothion-oxon. On the basis of their metabolic profiling, the possible metabolic pathways involved in phase I and II metabolism of FNT by <I>C. elegans</I> was proposed. We also found that <I>C. elegans</I> was able to efficiently and rapidly degrade other organophosphorus pesticides (OPs). Thus, these results will provide insight into understanding of the fungal degradation of FNT and the potential application for bioremediation of OPs. Furthermore, the ability of <I>C. elegans</I> to mimic mammalian metabolism would help us elucidate the metabolic fates of organic compounds occurring in mammalian liver cells and evaluate their toxicity and potential adverse effects.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jafcau/2017/jafcau.2017.65.issue-49/acs.jafc.7b04273/production/images/medium/jf-2017-04273g_0009.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jf7b04273'>ACS Electronic Supporting Info</A></P>

Rock-breaking analysis model of new drill bit with tornado-like bottomhole model

Jia-lin Tian,Chang-fu Yuan,Lin Yang,Chuan-hong Fu,Gang Liu,Zhi Yang,Chun-ming Wu 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.4

For improving the rock-breaking efficiency of oil and gas drill bits, a new drill bit is presented with tornado-like bottomhole model(named swirling cutting bit). The new drill bit cutter breaks rock with shocking and cutting effect during the drilling process, and theelements on largest ring cross the borehole center with high speed. It can effectively improve the center rock-breaking efficiency. Meanwhile,for all cutters on different rings breaking rock at the same time, it can optimize the rock-breaking volume of each element andimprove the bit service life. To analyze the interaction features between cutters and rock, the position equations are established by thecylindrical coordinates and complex movement principles, and then the velocity and acceleration equations can be obtained. Based on thenumerical example results, this paper analyzes the bottomhole model, the contact section, and the distribution features of velocities andaccelerations on different rings. By analyzing the acceleration results, we can study the failure mechanism of cutters. At the same time,lab experiments test the bottomhole model and rock-breaking features, and it verifies the accuracy of calculation method and equations. Moreover, the analysis method and models are also applicable to other types of bits or composite bits, and the inputting parameters needcorresponding adjustment for different type of bits.

Nanophotonic-Engineered Photothermal Harnessing for Waste Heat Management and Pyroelectric Generation

Wang, Xiao-Qiao,Tan, Chuan Fu,Chan, Kwok Hoe,Xu, Kaichen,Hong, Minghui,Kim, Sang-Woo,Ho, Ghim Wei American Chemical Society 2017 ACS NANO Vol.11 No.10

<P>At present, there are various limitations to harvesting ambient waste heat which include the lack of economically viable material and innovative design features that can efficiently recover low grade heat for useful energy conversion. In this work, a thermal nanophotonic-pyroelectric (TNPh-pyro) scheme consisting of a metamaterial multilayer and pyroelectric material, which performs synergistic waste heat rejection and photothermal heat-to-electricity conversion, is presented. Unlike any other pyroelectric configuration, this conceptual design deviates from the conventional by deliberately employing back-reflecting NIR to enable waste heat reutilization/recuperation to enhance pyroelectric generation, avoiding excessive solar heat uptake and also retaining high visual transparency of the device. Passive solar reflective cooling up to 4.1 degrees C is demonstrated. Meanwhile, the photothermal pyroelectric performance capitalizing on the back-reflecting effect shows an open circuit voltage (V-oc) and short circuit current (I-sc) enhancement of 152 and 146%, respectively. In addition, the designed photoactive component (TiO2/Cu) within the metamaterial multilayer provides the TNPh-pyro system with an effective air pollutant photodegradation functionality. Finally, proof-of-concept for concurrent photothermal management and enhanced solar pyroelectric generation under a real outdoor environment is demonstrated.</P>

Parallel match is an important concept for the parallel processing of the production system(PS). Considing the PS as a kernel of deduction knowledge, this paper presents a prototype of knowledge-based machine-KBM91 composed of the host-slave machine. The aim is to solve the match bottleneck problem of the PS. Furthermore, the paper analyzes the designing thought, the working process and the architecture of KBM91, and proposes a new kind of knowledge-based language(KBL) which has been realized at present.
