Miao Qi,Ying Wang,Guangtao Chang,Ruoxin Li 한국섬유공학회 2022 Fibers and polymers Vol.23 No.7

With the global climate changing, people are more aware of energy consumption and are interested in energysavingproducts or materials. One way to reduce energy consumption to improve personal thermal management efficiency isurgently needed. Therefore, we provide an alternative energy-saving method that will improve fabrics’ thermal managementby blocking infrared heat and ultraviolet light from solar radiation. A phase-inversion technique was developed to preparepoly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) micro-size and nano-size composite pore structure which canblock out the sun and be coated on fabric material. Meanwhile, by adding hydrophobic SiO2 aerogel particles (SA) to thesystem, the surface of coating became superhydrophobic, it improved waterproof and moisture-permeable properties offabric which are important for wearing or using pleasantly. It can be used for any outdoor application such as tents, clothing,or some indoor use as well.

Qi Fei-Yan,Zhu Zhou-Hai,Li Meng,Guan Ying,Peng Qi-Yuan,Lu She-Ming,Liu Zhi-Hua,Wang Ming-Feng,Miao Ming-Ming,Chen Zhang-Yu,Li Xue-Mei,Bai Jie,Yao Jian-Hua 한국유전학회 2022 Genes & Genomics Vol.44 No.11

Background: Smoking behavior is influenced by multiple genes, including the bitter taste gene TAS2R38. It has been reported that the correlation between TAS2R38 and smoking behavior has ethnicity-based differences. However, the TAS2R38 status in Chinese smokers is still unclear. Objective: This study aims to investigate the possible relationship between genetic variations in TAS2R38 (A49P, V262A and I296V) and smoking behaviors in the Han Chinese population. Methods: The haplotype analyses were performed and smoking behavior questionnaire was completed by 1271 individuals. Genetic association analyses for smoking behavior were analyzed using chi-square test. Further, for investigating the molecular mechanism of TAS2R38 variants effect on smoking behavior, we conducted TAS2R38-PAV and TAS2R38-AVI expression plasmids and tested the cellular calcium assay by cigarette smoke compounds stimulus in HEK293. Results: Significant associations of genetic variants within TAS2R38 were identified with smoking behavior. We found a higher PAV/PAV frequency than AVI/AVI in moderate and high nicotine dependence (FTND ≥ 4; X2 = 4.611, 1 df, p = 0.032) and strong cigarette smoke flavor intensity preference (X2 = 4.5383, 1 df, p = 0.033) in participants. Furthermore, in the in vitro cellular calcium assay, total particle matter (TPM), N-formylnornicotine and cotinine, existing in cigarette smoke, activated TAS2R38-PAV but not TAS2R38-AVI-transfected cells. Conclusion: Our data highlights that genetic variations in TAS2R38 are related to smoking behavior, especially nicotine dependence and cigarette smoke flavor intensity preference. Our findings may encourage further consideration of the taste process to identify individuals susceptible to nicotine dependence, particularly Han Chinese smokers.

Influencing Factors of High PTSD Among Medical Staff During COVID-19: Evidences From Both Meta-analysis and Subgroup Analysis

Qi, Guojia,Yuan, Ping,Qi, Miao,Hu, Xiuli,Shi, Shangpeng,Shi, Xiuquan Occupational Safety and Health Research Institute 2022 Safety and health at work Vol.13 No.3

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I² statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%-40%) and 38% (95% CI: 30%-45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion: Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.

Zhou, Qi,Jiang, Jue,Shang, Xu,Zhang, Hong-Li,Ma, Wen-Qi,Xu, Yong-Bo,Wang, Hua,Li, Miao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.17

Background: The purpose of this study was to investigate the correlation of contrast-enhanced ultrasonographic (CEUS) features with microvessel density (MVD) in papillary thyroid carcinomas (PTCs). Materials and Methods: Contrast-enhanced ultrasonography (CEUS) was performed in 62 patients (17 men and 45 women) with PTC. Tomtec software was applied to analyze the time intensity curve of CEUS. Immunohistochemistry was performed to evaluate the level of MVD in papillary thyroid carcinoma. Then the relationship between quantitative feature and the level of MVD was analyzed using SPSS 16.0 software. Results: The mean peak intensity of PTC tissues was lower than that of peripheral thyroid parenchyma ($61.9{\pm}11.8%$ vs 100%, p<0.05). The MVDs of CD34 and CD31 antibodies staining were $38.0{\pm}6.1$ and $37.9{\pm}5.1$ respectively in 62 PTC samples. A significantly positive correlation was observed between peak intensity and MVD in PTC tissues ($P_{CD34}$<0.01, $r_{CD34}$=0.838, $P_{CD31}$<0.01, $r_{CD31}$=0.837). Conclusions: The peak intensity in CEUS could reflect the MVD in PTC tissues. Therefore, quantification of CEUS seems to be helpful for assessment of MVD in PTC tissues.

Discrete-Time Adaptive Iterative Learning Control with Unknown Control Directions

Miao Yu,Jianliang Zhang,Donglian Qi 제어·로봇·시스템학회 2012 International Journal of Control, Automation, and Vol.10 No.6

An adaptive iterative learning control scheme is proposed for a class of discrete-time nonlinear systems with random initial conditions and iteration-varying desired trajectories. The discrete Nussbaum gain method is incorporated into the control design to tackle the problem associated with the lack of a priori knowledge of the control directions. The proposed control algorithm guarantees the boundedness of all the signals in the controlled system. The tracking error converges to zero asymptotically along the iterative learning axis. The effectiveness of the proposed control law is veri-fied through numerical simulation.

Miao, Cui-Ping,Mi, Qi-Li,Qiao, Xin-Guo,Zheng, You-Kun,Chen, You-Wei,Xu, Li-Hua,Guan, Hui-Lin,Zhao, Li-Xing The Korean Society of Ginseng 2016 Journal of Ginseng Research Vol.40 No.2

Background: Rhizospheric fungi play an essential role in the plantesoil ecosystem, affecting plant growth and health. In this study, we evaluated the fungal diversity in the rhizosphere soil of 2-yr-old healthy Panax notoginseng cultivated in Wenshan, China. Methods: Culture-independent Illumina MiSeq and culture-dependent techniques, combining molecular and morphological characteristics, were used to analyze the rhizospheric fungal diversity. A diffusion test was used to challenge the phytopathogens of P. notoginseng. Results: A total of 16,130 paired-end reads of the nuclear ribosomal internal transcribed spacer 2 were generated and clustered into 860 operational taxonomic units at 97% sequence similarity. All the operational taxonomic units were assigned to five phyla and 79 genera. Zygomycota (46.2%) and Ascomycota (37.8%) were the dominant taxa; Mortierella and unclassified Mortierellales accounted for a large proportion (44.9%) at genus level. The relative abundance of Fusarium and Phoma sequenceswas high, accounting for 12.9% and 5.5%, respectively. In total,113 fungal isolates were isolated from rhizosphere soil. They were assigned to five classes, eight orders (except for an Incertae sedis), 26 genera, and 43 species based on morphological characteristics and phylogenetic analysis of the internal transcribed spacer. Fusarium was the most isolated genus with six species (24 isolates, 21.2%). The abundance of Phoma was also relatively high (8.0%). Thirteen isolates displayed antimicrobial activity against at least one test fungus. Conclusion: Our results suggest that diverse fungi including potential pathogenic ones exist in the rhizosphere soil of 2-yr-old P. notoginseng and that antagonistic isolates may be useful for biological control of pathogens.

<P><B>Abstract</B></P> <P>Serotonin (5-hydroxytryptamine, 5-HT) plays a key role in modulating diverse physiological processes and behaviors in both protostomes and deuterostomes. These functions are mediated through the binding of serotonin to its receptors, which are recognized as potential insecticide targets. We investigated the sequence, pharmacology and tissue distribution of three 5-HT receptors (Piera5-HT<SUB>1A</SUB>, Piera5-HT<SUB>1B</SUB>, Piera5-HT<SUB>7</SUB>) from the small white butterfly <I>Pieris rapae</I>, an important pest of cultivated cabbages and other mustard family crops. Activation of Piera5-HT<SUB>1A</SUB> or Piera5-HT<SUB>1B</SUB> by 5-HT inhibited the production of cAMP in a dose-dependent manner. Stimulation of Piera5-HT<SUB>7</SUB> with 5-HT increased cAMP level significantly. Surprisingly, with the exception of 5-methoxytryptamine, agonists including α-methylserotonin, 8-Hydroxy-DPAT and 5-carboxamidotryptamine activated these receptors poorly. The results are consistent with previous findings in <I>Manduca sexta</I>. All three receptors were blocked by methiothepin, but ketanserin and yohimbine were not effective. The selective mammalian 5-HT receptor antagonists SB 216641 and SB 269970 displayed potent inhibition effects on Piera5-HT<SUB>1B</SUB> and Piera5-HT<SUB>7</SUB> respectively. The results we achieved here indicate that the pharmacological properties of Lepidoptera 5-HT receptors are quite different from those in other insects and vertebrates and may contribute to development of new selective pesticides. This study offers important information on three 5-HT receptors from <I>P. rapae</I> that will facilitate further analysis of the functions of 5-HT receptors in insects.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Serotonin receptors Piera5-HT<SUB>1A</SUB>, Piera5-HT<SUB>1B</SUB>, and Piera5-HT<SUB>7</SUB> from <I>Pieris rapae</I> were cloned and examined. </LI> <LI> Upon serotonin activation, Piera5-HT<SUB>1A</SUB> and Piera5-HT<SUB>1B</SUB> inhibited cAMP production whereas Piera5-HT<SUB>7</SUB> induced it. </LI> <LI> All three receptors were poorly activated by serotoninergic agonists, indicating their distinct pharmacological properties. </LI> <LI> All three receptors were blocked by methiothepin; SB 216641 and SB 269970 inhibited Pr5-HT<SUB>1B</SUB> and Pr5-HT<SUB>7</SUB>, respectively. </LI> <LI> All three receptors were highly expressed in neuronal tissues while Pr5-HT<SUB>7</SUB> mRNA predominated in the gut. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

브랜드는 이제 기업의 가장 중요한 무형자산 중 하나로 간주되며, 시장 경쟁은 주로 브랜드 간의 경쟁으로 이루어지고 있다. 이러한 상황에서 스토리텔링은 브랜드 이미지를 형성하는데 효과적인 도구로 인식되고 있다. 스토리텔링은 기업과 소비자 간의 효율적인 소통 방식으로 여겨지며, 이를 통해 복잡한 정보를 소비자에게 쉽게 전달하고 설득할 수 있다. 스토리텔링을 통해 기업은 내포된 가치와 핵심 메시지를 소비자에게 전달하고 공감을 얻어 소비자와 강한 관계를 형성할 수 있다. 스토리텔링은 이미 마케팅 분야에서 주목받고 있는 중요한 주제 중 하나다. 본 연구는 브랜드 스토리텔링의 정의, 다양한 유형, 주요 구성 요소, 역할, 연구 동향의 5개 측면에서 정리하고 분석하며, 기준 연구를 바탕으로 브랜드 스토리텔링의 현재 연구공백을 파악하고 미래의 연구 방향을 제시하고자 한다. Nowadays, brand has become the most important intangible asset of a company, and the competition in the market has become a competition of brands. Narrative is considered to be an effective means of branding. Storytelling is an effective way for companies to communicate with consumers. Since stories do not require complex information processing by consumers, the content conveyed in the form of stories makes it easier for consumers to understand and be persuaded. Through storytelling, companies communicate their values to consumers, allowing them to empathize with them and build relationships with them. Brand storytelling has become one of the hot topics in the marketing field. This study collates and analyzes the research results of brand storytelling from five aspects: definition, types, components, roles, and research trends, and proposes suggestions for future research directions in view of the shortcomings of current research.

지난 10년 동안 Airbnb, Uber, Lyft, TaskRabbit로 대표되는 C2C 공유와 Mobike, ofo, Spinlister로 대표되는 B2C 공유라는 두 가지 새로운 공유 비즈니스 모델이 등장했다. 특히 지난 팬데믹 동안 세계 경제 성장률 감소와 실업률 상승으로 공유경제의 발전은 둔화되는 경향을 보였다. 하지만 정보기술의 발전과 소비자의 환경 보호라는 새로운 소비 개념의 전환으로 공유경제는 새로운 발전의 기회를 맞이하고 있다. 공유경제의 부상은 마케팅 분야의 광범위한 관심을 불러 일으켰지만, 마케팅 이론과 실무에 미치는 직접적인 영향은 여전히 불분명하다. 본 논문은 체계적인 정량적 문헌 분석을 통하여 우선 공유경제의 정의, 본질 및 특성에서 공유경제의 의미 파악을 목표로 한다. 둘째, 본 논문은 공유경제가 마케팅의 전통적인 신념과 실무에 미치는 영향, 즉 협력적 소비이론(Theory of Collaborative Consumption), 양자 플랫폼 이론(Theory of Two-Sided Platform) 및 기업운영이론(Theory of Firms Operations)의 분석 틀에 근거하여 소비자(참여 동기, 만족도 및 구매 의도), 공유플랫폼(동적 가격 결정, 평판 메커니즘, 검색 메커니즘 및 매칭 메커니즘)과 기업(운영: 공급망/채널, 관리: 기업 가격 결정/제품전략)의 3대 관점에서 공유경제 연구 진행을 정리하고 공유경제 참여 주체의 현재 문제점을 강조하며 공유경제 마케팅을 촉진하기 위한 미래 연구방향을 제공하였다. 마지막으로 공유경제 시장 참여 주체인 소비자, 공유플랫폼 및 기업운영/관리에 대한 타당성을 제안하였다. 본 연구는 공유경제의 현실적 실무를 지도하는 관리자 측면에서의 시사점을 제시하고 마케팅 연구자들이 공유경제의 흐름을 파악하고 앞으로 나아갈 방향을 제시하는 것을 목적으로 하였다. In the past decade, the emergence of two new sharing business models, C2C sharing represented by Airbnb, Uber, Lyft and TaskRabbit and B2C sharing represented by Mobike, ofo and Spinlister, has led to the rise of various studies on this topic in the marketing discipline. However, the impact of the sharing economy on marketing thought and practice is still unclear. Based on scientific quantitative research and literature analysis, this paper firstly grasps the connotation of sharing economy from the definition, essence and characteristics. Secondly, the article also studies the impact of the traditional beliefs and practice of the sharing economy on marketing. According to the Theory of Collaborative Consumption, Theory of Two-sided market and Theory of Firms Operations analytical framework, From consumers (Engagement Motivation, Satisfaction and Purchase Intent), Sharing Platforms (Dynamic Pricing, Reputation Mechanism, Search Mechanism and Matching Mechanism) and Enterprises (Operations: Supply Chain/Channel, Management: Enterprise Pricing/Product Strategy) three major perspectives, sort out the progress of the sharing economy, emphasize the current problems of participating entities of the sharing economy, and provide the future research direction to promote sharing economic marketing. Finally, a set of forward-looking guiding principles is proposed for the sharing economy market participants-consumers, sharing platforms, and business operations management. In summary, this paper aims to help guide management and governance insights into the scientific practice of the sharing economy and help marketing scholars not only keep pace with the sharing economy, but also shape its future direction.

소셜 미디어 마케팅은 통합된 마케팅 커뮤니케이션의 일환으로 자리매김하고 있으며, 기업과 소비자 간 강력한 관계를 구축하고자 하는데 큰 도움이 되고 있다. 전문 블로거가 생성한 콘텐츠를 체험 관련 콘텐츠와 프로모션 관련 콘텐츠로 구분하고 소비자의 제품 정보 및 리스크 인식 수준이 다르기 때문에 그들의 정보 채택 의도에 영향을 미친다. 콘텐츠 마케팅 과정에서 외부 환경은 소비자 가치 및 리스크 인식에 영향을 미치는 중요한 요인 중 하나다. 따라서 기업은 제품 콘텐츠 유형에 따라 적절한 환경을 선택하여 소비자의 정보채택 의도를 강화해야 한다. 본 연구에서는 일상에서 흔한 볼 수 있는 사회 현상인 사회적 크라우딩을 시각으로 휴리스틱 체계적 모델 이론을 적용하여 사회적 크라우딩과 전문 블로거 생성 콘텐츠 유형이 소비자의 정보 채택 의도에 미치는 영향을 탐색하였다. 본 연구는 3가지 실험을 통해 연구 가설을 검증되었다. 즉, 전문 블로거 생성 콘텐츠 유형과 사회적 크라우딩 간의 상호작용 효과가 소비자 정보 채택에 영향을 미친다. 또한, 정보 처리 유창성이 전문가 생성 콘텐츠 유형과 시회 크라우딩이 소비자의 정보 채택에 미치는 영향에서 매개 효과를 나타났다. 그리고, 소비자의 지식수준이 전문가 생성 콘텐츠 유형과 사회적 크라우딩 간의 상호작용 효과가 소비자 정보 채택에 미치는 영향에서 조절효과를 있는 결과를 검증됐다. 이론적으로 본 연구는 사회적 그라우딩 및 콘텐츠 마케팅 분야의 연구를 풍부하게 되고 기업이 마케팅 전략을 수립하는 데 도움이 되는 시사점도 제공하였다. 즉 다양한 유형의 콘텐츠 마케팅 활동을 수행하기 위해 적합한 사회적 크라우딩 상황을 선택하는 것이 중요하다는 것이다. Social media marketing has become an integral part of integrated marketing communications, playing a significant role in establishing strong relationships between businesses and consumers. The study focuses on categorizing content generated by professional bloggers into experiential and promotional types, considering that consumers’ levels of product information and risk perception vary, influencing their intent to adopt information. Therefore, businesses should select appropriate environments based on the type of product content to enhance consumer’ willingness to adopt information. Consequently, the exploration of how to effectively increase consumers’ intent to adopt information by selecting environments is a relevant issue. In this study, the common social phenomenon of social crowding is explored visually, applying the heuristic-systematic model theory. The study investigates the impact of social crowding and professional blogger content types on consumers’ intent to adopt information. The research hypotheses were validated through three experiments, demonstrating that the interaction effect between professional user-generated content types and social crowding influences consumer information adoption. Furthermore, information processing fluency showed a mediating effect on the impact of professional generated content types and social crowding on consumer information adoption. The study also verified a moderating effect of consume knowledge levels on the interaction effect between professional generated content types and social crowding on consumer information adoption. Theoretically, this study enriches research in the fields of social crowding and content marketing, providing insights for businesses in formulating marketing strategies. It emphasizes the importance of selecting appropriate social crowding situations for various types of content marketing activities.
