Yali Ma,Jiayong Wei,Cancan Li,Chen Liang,Guochao Liu 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.7

Aiming at the problem that the multi-objective evaluation of performance and the weighting coefficients of indexes is difficult to find, a fuzzy comprehensive performance evaluation method of rolling linear guide (RLG) is proposed. Considering the static and dynamic indexes, a structure model containing nine weighting coefficients was constructed. The performance evaluation function was established by the compromise programming method and the average power method, while weighting coefficients were determined by the improved analytic hierarchy process (I-AHP); the mathematical model was obtained to evaluate the RLG in a certain application. The evaluation results show that the confidence of the static, dynamic and comprehensive performance of the RLG is 59.21 %, 81.97 %, and 63.34 %, respectively. The feasibility of the method was verified by numerical simulation. This method indicates the pros and cons of the performance of the RLG and also indicates the direction for its optimized design.

Yali, Liang,Zhichao, Qiu,Yaohe, Li,Anping, Liu,Zhixiong, Chen,Huliwen, Huliwen,man, Luo,jing, He,Xiaoyang, Xiaoyang,Hai, Lan Techno-Press 2021 Advances in nano research Vol.10 No.6

Disseminated candidiasis (DC) arising from nosocomial fungal infection is a life-threatening complication in critically ill, nonneutropenic patients. The overall nosocomial fungal infection rate in United States hospitals doubled from 1980-1990. Until recently, amphotericin B was the only agent available for the treatment of life-threatening candidal infections, but its use is plagued by toxicities including nephrotoxicity and infusion-related reactions such as rigors and hypotension. The availability of fluconazole, which is regarded more much less toxic than amphotericin B, prompted a surge in research to determine if it is as efficacious in the management of candidemia and hematogenously disseminated candidiasis. Complicating the interpretation of studies is the broad range of infection severity, from candidemia that may be transient and self-limiting to life-threatening hematogenously disseminated candidiasis. This study has used the models of Artificial neural network (ANN) and Support Vector regression (SVR) to accurately assess the clinical trials comparing fluconazole and amphotericin B demonstrate the efficacy of fluconazole for catheter-associated candidemia in critically ill patients when the likely pathogen is Candida albicans. As a result, Amphotericin B should remain the first-line agent for the management of candidemia and hematogenously disseminated candidiasis in all other patients. Also, SVR could accurately assess the efficacy of fluconazole for catheter-associated candidemia in critically ill patients.

Understanding global changes of physiological processes at the molecular level during the growth of Streptococcus thermophilus is essential for the rational design of cultivation media and the optimization of bioprocesses. Transcriptomics and proteomics were combined to investigate the global changes at the transcript and protein level during the growth of S. thermophilus. The expression of 1396 genes (FDR ≤ 0.001) and 876 proteins (P < 0.05) changed significantly over time. The most remarkable growth phase dependent changes occurred in the late-lag phase and were related to heterofermentation, glycolysis, peptidoglycan biosynthesis, conversion between amino acids and stress response. The present results could provide theoretical guidance for high-cell-density culture, help design cultivation media, and help attain a high biomass of S. thermophilus.

WHEN GRATITUDE BACKFIRES: HOW CULTURE SHAPES THE CONSUMER SATISFACTION

Yali Fan,Rong Chen,Feng He 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

This paper examines the impact of thanks from the sellers on consumer satisfaction in the tourism industry. Study 1 shows that thanks from the sellers (vs. no thank from the sellers) will decrease consumer satisfaction. In this process, perceived fairness and perceived value play a serial mediation role. Study 2 shows that the pricing type (the fixed price vs. the flexible price) plays a moderate role on the impact of thanks from the sellers at the end of a transaction on consumer satisfaction. This paper introduces transaction utility theory and culture difference to explain the seemingly inconsistent phenomenon. Introduction The present studies focus on retailers expressing gratitude and, especially, how the communication of retailer expressing gratitude or not affects consumer satisfaction under the tourism purchase environment. Image that you encounter a seller is selling the souvenirs in the tourist spot you just visit, you would like to buy one of the souvenirs, such as a special cup with the souvenirs logo, you conclude a deal with the seller eventually, after that, the seller thanks for your purchasing and you leave. One question arises, will consumers feel less satisfaction when sellers say nothing than when they say “Thank you” at the end of a transaction? Theoretical Background Thanking is one of the speech acts or communicative acts frequently and abundantly utilized in human interactions, even though, most of these studies have focused on a western perspective, little is known about the experience of tourists from Asia. In western countries, people are accustomed to saying thank you after the benefit of others. Some behavioral responses may resemble the expression of gratitude (e.g., saying thank you to a waiter in a restaurant), but may instead be an automatic polite response not grounded in emotion (Buck 2004; Emmons and McCullough 2003; Fazalehasan et al 2017). However, in Somali and China culture, people are not used to expressing thanks, which makes many Americans or Australian feel rude or impolite (Chiu and Hong 2013; Robertson 2014). Here we test the prediction that gratitude from retailers may affect consumer satisfaction in a potentially counterintuitive manner. In other words, we hypothesize that gratitude from the retailer may lead to lower consumer satisfaction. This prediction draws from both the existing literature on gratitude as well as from research on culture difference and transaction utility theory from the response to gratitude. Research Design Two experiments have been conducted to test the hypotheses. Study 1 will provide support for the three central hypotheses regarding perceived fairness inference (hypothesis 1), perceived value inferences (hypothesis 2), and consumer satisfaction (hypothesis 3). Study 2 will test an important boundary condition. This study shows that the proposed negative effect of saying thank you (vs. saying nothing) holds only if the price of product is fixed. Result and Conclusion In the study 1, we found that sellers saying thank you after the transaction leads to less consumer satisfaction. Therefore, an important contribution of our work emerges from our melding of the literature on perceived fairness and value and demonstrating that gratitude from the sellers dictates which literature is more applicable in relationship marketing. Furthermore, we also examined the mechanism in study 2 and explore a boundary condition. We discovered that when the price of a souvenir is fixed, consumers feel more satisfaction when sellers say nothing than when they say “Thank you” at the end of a transaction. Conversely, when the price of a souvenir is not fixed, which is to say when consumers can bargain in the store, consumers feel less satisfaction when sellers say nothing than when they say “Thank you” after the transaction

Yunyun Liu,Yali Hu,Qiran Cai,Xiangju Xu,Yin Chen,SHAOMING HUANG 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.1

High-quality single-walled carbon nanotubes (SWNTs) with narrow diameter distribution can be generated from well-defined Si8O12 nanoclusters structure which form from thermal decomposition of chemically modi¯ed polyhedral oligomeric silsesquioxane (POSS). The nanosized SixOy particles were proved to be responsible for the SWNT growth and believed to be the reason for the narrow diameter distribution of the as-grown SWNTs. This could be extended to other POSS. The SWNTs grown from the nanosized SixOy particles were found to be semiconducting enriched SWNTs (s-SWNTs). A facile patterning technology, direct photolithography, was developed for generating SWNT pattern, which is compatible to industrial-level fabrication of SWNTs pattern for device applications. The metal-free growth together with preferential growth of s-SWNTs and patterning in large scale from the structure-defined silicon oxide nanoclusters not only represent a big step toward the control growth of SWNTs and fabrication of devices for applications particularly in nanoelectronics and biomedicine but also provide a system for further studying and understanding the growth mechanism of SWNTs from nanosized materials and the relationship between the structure of SWNT and nonmetal catalysts.

Bee venom has been used for treating various diseases for a long time. However, the bioactive constituents of bee venom and its mechanisms remain poorly understood. In the present study, phospholipase A2 (Bt-PLA2) cDNA was cloned, and a mature form of Bt-PLA2 was purified from bumblebee venom (Bombus terrestris). The differentiation induction and apoptosis induction activities of Bt-PLA2 on chronic myelogenous leukemia (CML) K562 cells were also evaluated. Bt-PLA2 cDNA has 540 nucleotides that encode a 180-amino-acid protein. The purified, mature form of Bt-PLA2 was an 18-kDa protein, and it inhibited K562 cell growth, determined by an IC50 value of 29.5 ng/μl. Moreover, Bt-PLA2 induced erythroid differentiation of K562 cells in a dose-dependent manner, and this was supplemented with the upregulation of glycophorin A (GPA) mRNA expression. Bt-PLA2- induced apoptosis, analyzed by DAPI staining, was correlated with the result analyzed by AnnexinV-FITC/PI binding. Furthermore, activation of caspase 3 and poly ADP-ribose polymerase (PARP) and inhibition of p-Akt, determined by western blot, further demonstrated that Bt-PLA2 induced apoptosis mainly through the Akt pathway. The parallel induction of erythroblasts differentiation of K562 cells and apoptosis due to Bt-PLA2 treatment demonstrated the potential use of Bt-PLA2 as an anti-leukemia drug lead.

Xiaohu Luo,Bo Chen,Ji Li,Bang Lan,Chenliang Zhou,Zhengxing Ren,Chenggang Ci,Yali Liu 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.124 No.-

Herein, we report a rational design and synthesis of a highly-efficient and eco-friendly glucomannanderivative (GA-2) by the introduction of the thiazole and Schiff base groups into glucomannan (GA). After confirmation of GA-2 by the spectroscopic methods, it was introduced as corrosion inhibitor withexcellent anti-corrosion action for mild steel (MS) in the simulated seawater. As-obtained results revealthat GA-2 has a significantly enhanced anticorrosion performance, and its inhibitive efficiency reaches98.8% at the 0.5 mmol L1 inhibitor concentration, much higher than that of GA (69.8%) and the intermediatederivative GA-1 (81.2%). The significantly enhanced protection performance could be attributed tothe rich S heteroatoms, aromatic rings, and Schiff base groups in the GA-2, which strongly promotes thechemisorption as well as physisorption between GAD and MS. X-ray photoelectron spectroscopy (XPS)results, show that the appearance of N-Fe and S-Fe bonds confirms the strongly anchoring interactionbetween GA and MS. Furthermore, according to the quantum chemical calculations, the results fromthe lowe energy gap and radical distribution function (RDF) analyses further confirm the strongchemisorption of GA-2 at the surface of steel, which illustrates the excellent inhibition performance atthe molecule and atom level.
