From the perspective of social media (self-media), this research analyzes the fusion relationship between different dimensions of FMCG packaging design and product purchase intention, and puts forward corresponding views and strategies at the theoretical and application levels. In the social media era, the right of information control, the right of choice, and the right of discourse gradually incline to the public, and the one-way information output in the field of United Media is transforming into the information interaction and multiple control of Focus Media. All brands are using a more flexible way to export brand culture and values. At this point, the field of product packaging is an important export. The role of product packaging has expanded from a static storage carrier to a modern circulation medium, and has become an important channel connecting brands and consumers. Excellent product packaging can not only stimulate consumers to purchase, but also, through the spontaneous sharing of consumers in social media, achieve propagation fission and maximize the promotion of brand communication. In previous studies, few studies have been conducted on product packaging factors and their influencing mechanisms with purchase intention from the perspective of brand communication, therefore further research is needed to enrich theoretical research in this field and optimize product packaging strategies. This paper analyzes and refines the obtained interview data, and obtains four dimensions of FMCG packaging: functionality, sensation, emotionality and topicality, and constructs the model of FMCG packaging’s influence mechanism on purchase intention. Relevant research hypotheses are put forward. Research has found that the functionality, sensation, emotionality, and topicality of FMCG packaging have a significant impact on purchase intention, and topicality has the greatest impact. Topic has become the primary factor influencing consumers’ FMCG purchase intention in the social media era. Combining the research conclusion of this paper with the status quo of enterprise marketing, this paper puts forward corresponding marketing suggestions for the packaging design of the FMCG industry.

Mao Po-Hsin,박영권,Lin Yi-Feng,Thanh Bui Xuan,Tuan Duong Dinh,Ebrahimi Afshin,Lisak Grzegorz,Tangcharoen Thanit,Lin Kun-Yi Andrew 한국화학공학회 2023 Korean Journal of Chemical Engineering Vol.40 No.12

As disinfection is employed extensively, disinfection by-product bromate has become an emerging environmental issue due to its carcinogenic toxicity. For developing an effective alternative approach for reducing bromate, cobalt and nickel-based Prussian Blue (PB) analogues are proposed here for incorporating a convenient reducing agent, NaBH4 (i.e., a H2-rich reagent) for reducing bromate to bromide as cobalt and nickel are recognized as effective metals for catalyzing hydrolysis of NaBH4, and PB exhibits versatile catalytic activity. While CoPB and NiPB are comprised of the same crystalline structure, CoPB exhibits slightly higher specific surface area, more reductive surface, and more superior electron transfer than NiPB, enabling CoPB to accelerate bromate reduction. CoPB also exhibits a higher affinity towards NaBH4 than NiPB based on density functional theory calculations. Moreover, CoPB also exhibits a relatively low activation energy (i.e., 59.5 kJ/mol) of bromate reduction than NiPB (i.e., 63.2 kJ/mol). Furthermore, bromate reduction by CoPB and NiPB could be also considerably enhanced under acidic conditions, and CoPB and NiPB could still effectively remove bromate even in the presence of nitrate, sulfate and phosphate. CoPB and NiPB are also validated to be recyclable for reducing bromate, indicating that CoPB and NiPB are promising heterogeneous catalysts for reducing bromate.

Mao Yin,Huang Chao,Zhou Xuan,Han Runhua,Deng Yu,Zhou Shenghu 한국미생물·생명공학회 2023 Journal of microbiology and biotechnology Vol.33 No.10

Although rational genetic engineering is nowadays the favored method for microbial strain improvement, building up mutant libraries based on directed evolution for improvement is still in many cases the better option. In this regard, the demand for precise and efficient screening methods for mutants with high performance has stimulated the development of biosensor-based highthroughput screening strategies. Genetically encoded biosensors provide powerful tools to couple the desired phenotype to a detectable signal, such as fluorescence and growth rate. Herein, we review recent advances in engineering several classes of biosensors and their applications in directed evolution. Furthermore, we compare and discuss the screening advantages and limitations of two-component biosensors, transcription-factor-based biosensors, and RNA-based biosensors. Engineering these biosensors has focused mainly on modifying the expression level or structure of the biosensor components to optimize the dynamic range, specificity, and detection range. Finally, the applications of biosensors in the evolution of proteins, metabolic pathways, and genome-scale metabolic networks are described. This review provides potential guidance in the design of biosensors and their applications in improving the bioproduction of microbial cell factories through directed evolution.

The influence of synergistic effects of hexakis (4-nitrophenoxy) cyclotriphosphazene and POE-g-MA on anti-dripping and flame retardancy of PET

Xuan Zhang,ZhiPing Mao,Qian Wu,LinPing Zhang 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.3

In this report, hexakis (4-nitrophenoxy) cyclotriphosphazene (HNCP) and ethylene–octene copolymer grafted-maleic anhydride (POE-g-MA) were blended with pure PET together. The fire retardant ability and thermal stability of PET/HNCP/POE-g-MA were investigated respectively. The results indicated that HNCP and POE-g-MA had a synergic effect on the dripping resistance of PET besides the enhancement in flame retardancy to a certain degree. LOI values of the polymers with both POE-g-MA and 10 wt%HNCP were higher than that of pure PET and no drips just containing 1 wt%POE-g-MA. The reason was that HNCP could be well dispersed in PET when POE-g-MA was added, forming a more effective char layer and preventing dripping of polymers. Indeed, the morphology of charred residue of PET/HNCP/POE-g-MA showed that a porous protective layer with a dense surface was formed. The thermogravimetric analysis revealed that addition of HNCP improved the thermal stability and the yield of char residue of the PET/POE-g-MA systems. Based on a series of experiment results, the synergistic effect of HNCP and POE-g-MA on the anti-dripping of PET was also discussed. In the PET/HNCP/POE-g-MA system, POE-g-MA played a role of compatibilizer. The improved compatibility and dispersion provided the composite with the ideal flame retardancy, thermal stability and anti-dripping property.

Wang, Xuan,Zhang, Peijie,Tang, Xingyu,Guan, Junjie,Lin, Xiaohuan,Wang, Yajie,Dong, Xiao,Yue, Binbin,Yan, Jinyuan,Li, Kuo,Zheng, Haiyan,Mao, Ho-kwang American Chemical Society 2019 The Journal of Physical Chemistry Part C Vol. No.

<P>Sodium rhodizonate (Na<SUB>2</SUB>C<SUB>6</SUB>O<SUB>6</SUB>) has very high theoretical capacity as a positive electrode material of sodium-ion batteries, but it still has problems such as low actual capacity and poor electronic/ionic conductivity. In order to improve its conductivity, we investigated its structure and electrical properties under high pressure. By performing in situ X-ray diffraction, Raman, infrared absorption, and alternating current impedance spectroscopy in the range of 0-30 GPa at room temperature, we observed a phase transition at ∼11 GPa, with the conductivity increasing by an order of magnitude. Above ∼20 GPa, Na<SUB>2</SUB>C<SUB>6</SUB>O<SUB>6</SUB> gradually amorphized. During the decompression process, the pressure regulation of the structure and properties of the material are reversible. Our study shows that applying external pressure is an effective tool to improve the conductivity of molecular battery materials. The investigation will help to obtain next-generation electrode materials.</P> [FIG OMISSION]</BR>

The impact of boarding on campus on the social-emotional competence of left-behind children in rural western China

Shutao Wang,Xuan Dong,Yaqing Mao 서울대학교 교육연구소 2017 Asia Pacific Education Review Vol.18 No.3

This study aimed to determine if boarding on campus benefited left-behind children’s social-emotional competence (SEC). We developed a SEC scale for the Chinese context and culture using exploratory factor analysis, confirmatory factor analysis, and reliability analysis. Data were collected from 6638 school-aged children from 74 rural boarding schools in 11 provinces in western China. The results indicated that children’s SEC was significantly affected by being left-behind, living on campus, and their cross-effects. Left-behind children had lower levels of SEC than those under parental guardianship. Children living on campus had fewer positive SEC skills than those who commuted between home and school. We also found that left-behind children living on campus had a higher negative SEC than left-behind children who were commuting every day. The SEC of left-behind but commuting children was higher than that of non-left-behind boarding school students. Food quality and caregivers’ service attitudes also significantly affected children’s SEC. Children who received good or medium quality food and good service from caregivers had higher SEC than those with poorer food and service. In conclusion, boarding on campus negatively affects left-behind children’s SEC. This suggests that more attention should be directed to the negative effects of boarding on campus, and boarding condition, and improving food quality and caregivers’ service.

Alpha-Hemolysin from Staphylococcus aureus Obstructs Yeast-Hyphae Switching and Diminishes Pathogenicity in Candida albicans

Yu Xiaoyu,Mao Yinhe,Li Guangbo,Wu Xianwei,Xuan Qiankun,Yang Simin,Chen Xiaoqing,Cao Qi,Guo Jian,Guo Jinhu,Wu Wenjuan 한국미생물학회 2023 The journal of microbiology Vol.61 No.2

The use of antibiotics can disrupt the body’s natural balance and increase the susteptibility of patients towards fungal infections. Candida albicans is a dimorphic opportunistic fungal pathogen with niches similar to those of bacteria. Our aim was to study the interaction between this pathogen and bacteria to facilitate the control of C. albicans infection. Alpha-hemolysin (Hla), a protein secreted from Staphylococcus aureus, causes cell wall damage and impedes the yeast–hyphae transition in C. albicans. Mechanistically, Hla stimulation triggered the formation of reactive oxygen species that damaged the cell wall and mitochondria of C. albicans. The cell cycle was arrested in the G0/G1 phase, CDC42 was downregulated, and Ywp1 was upregulated, disrupting yeast hyphae switching. Subsequently, hyphae development was inhibited. In mouse models, C. albicans pretreated with Hla reduced the C. albicans burden in skin and vaginal mucosal infections, suggesting that S. aureus Hla can inhibit hyphal development and reduce the pathogenicity of candidiasis in vivo.

Bu Ling,Zheng Tingting,Mao Chaoming,Fei Wu,Mou Xiao,Xu Chengcheng,Luo Xuan,Lu Qingyan,Dong Liyang,Wang Xuefeng 대한독성 유전단백체 학회 2021 Molecular & cellular toxicology Vol.17 No.4

Background Epigallocatechin-3-gallate is a natural polyphenolic compound that induces apoptosis in papillary thyroid cancer cells. However, its underlying molecular mechanism was not completely clarified. Objectives The present study demonstrated the role of apoptosis and autophagy in EGCG-treated papillary thyroid cancer cells and the relationship between these processes. Results EGCG significantly suppressed the viability of TPC-1 papillary thyroid cancer cells at an IC50 of 17.2 μM. EGCG induced TPC-1 cell apoptosis and cell cycle arrest at S phase and downregulated the protein expression of cyclin A and cyclin-dependent kinase-2. EGCG decreased reactive oxygen species levels, upregulated Bax expression, downregulated Bcl-2 expression and increased cytochrome C levels in the cytosol. Treatment with EGCG also increased the levels of cleaved caspase 3, cleaved caspase 9 and cleaved poly(ADP-ribose) polymerase. EGCG induced an autophagic response via the upregulation of the autophagy-related protein LC3-II and suppression of the AKT/mTOR signalling pathway. Autophagy inhibition further enhanced EGCG-induced cell apoptosis and ROS suppression, which indicated that autophagy played a cytoprotective role in EGCG-treated TPC-1 cells. Conclusion Taken together, these results demonstrated that autophagy inhibition was beneficial to EGCG–mediated apoptosis in papillary thyroid cancer cells.

Zhu Guanghui,Liu Lunan,Mao Yuzhou,Zhang Xinjun,Guo Yaoyao,Ai Lin,Jiang Runhao,Qin Chengming,Zhang Wei,Yang Hua,Yuan Shuai,Wang Lei,Ju Songqing,Wang Yongsheng,Sun Xuan,Yang Zhida,Wang Jinxin,Cheng Yan 한국원자력학회 2023 Nuclear Engineering and Technology Vol.55 No.2

The EAST ICRF system operating space has been extended in power and phase control with a low-level RF system for the new double-strap antenna. Then the multi-step power and periodic phase scanning experiment were conducted in L-mode plasma, respectively. In the power scanning experiment, the stored energy, radiation power, plasma impedance and the antenna's temperature all have positive responses during the short ramp-ups of PL;ICRF. The core ion temperature increased from 1 keV to 1.5 keV and the core heating area expanded from jZj 5 cmto jZj 10 cm during the injection of ICRF waves. In the phasing scanning experiment, in addition to the same conclusions as the previous relatively phasing scanning experiment, the superposition effect of the fluctuation of stored energy, radiation power and neutron yield caused by phasing change with dual antenna, resulting in the amplitude and phase shift, was also observed. The active control of RF output facilitates the precise control of plasma profiles and greatly benefits future experimental exploration.
