ABSTRACT
Based on the logistic growth model, the relationship between technology innovation and the evolution of economic forms was analyzed, and the main characteristics and basic laws of the five economic forms of hunter–gatherer, agriculture, industry, information, and bioeconomy were summarized. Based on a comprehensive and intensive scan of the latest bioeconomy development strategies of various countries, we summarized their two main driving forces from the technological supply side and economic and social demand side, as well as their four distinctive features, namely the comprehensiveness of science and technology innovation, the aggregation of industrial development, the globalization of development goals, and strong policy dependence. Finally, we proposed countermeasures to design the implementation path of the bioeconomy and improve the quality of the bioeconomy factor supply in terms of the development and application of biotechnology, the upgradation of bioindustry clusters, the positive policy environment, and the theorization of the bioeconomy.

As a core part of personal protective equipment (PPE), filter materials play a key role in individual protection, especially in the fight against the COVID‐19. Here, a high‐performance multiscale cellulose fibers‐based filter material is introduced for protective clothing, which overcomes the limitation of mutual exclusion of filtration and permeability in cellulose‐based filter materials. With the hierarchical biomimetic structure design and the active surface of multiscale cellulose fibers, high PM2.5 removal efficiency of ≈92% is achieved with the high moisture transmission rate of 8 kg m−2 d−1. Through a simple and effective dip‐coating and roll‐to‐roll process, the hierarchical filter materials can be made on a large scale and further fabricated into high‐quality protective clothing by industrial production equipment.

ABSTRACT
PURPOSE: The current study investigated the association between bicultural identity integration (BII, incorporating BII-harmony and BII-blendedness), national identity, and anxiety related to Coronavirus disease 2019 (COVID-19) among ethnic minority college students. In addition, this research examined the mediation role of power values in the relationship between BII, national identity, and COVID-19-related anxiety. METHODS: This cross-sectional research design made use of online surveys. Using convenience sampling, participants comprised 235 Chinese ethnic minority college students drawn from four colleges in the ethnic minority autonomous regions of China. Data were collected during June 2020. Participants mainly lived in ethnic minority communities or villages in southwest China before receiving higher education at urban campuses. RESULTS: Correlation analysis revealed that BII-harmony, BII-blendedness, and national identity were significantly negatively correlated with COVID-19-related anxiety. Mediation model analysis showed that power values were significantly positively correlated with COVID-19-related anxiety. Power values play a mediating role in the relationship between BII-harmony, national identity, and COVID-19-related anxiety, and have an inhibitory effect on this relationship. CONCLUSION: Our ï¬ndings indicate that BII-harmony and national identity could have the function of protecting ethnic minority college students from COVID-19-related anxiety. Emphasizing individualistic personal power values could increase COVID-19-related anxiety, whereas a collectivist identity reduces anxiety. These findings could provide another perspective on psychological interventions to reduce anxiety during the COVID-19 pandemic.
ABSTRACT
The aim of this study was to survey the prevalence of dry eye symptoms (DES) among doctors and nurses in the period of 2019, novel coronavirus (COVID-19) outbreak.To evaluate the DES of doctors and nurses worked at front-line hospitals with protective glasses for a mean time of 4 to 6âhours, a questionnaire developed by the researchers with the Ocular Surface Disease Index (OSDI) was used. These data were evaluated using descriptive statistics and correlation test with SPSS 22.0.The study included 13 doctors and 40 nurses, among which 16 were male and 37 were female, and the mean age of the participants was 32.43â±â5.15 years old. According to the OSDI scores, 64.15, 24.52, 7.54, and 3.77% of the participants experienced occasional, mild, moderate, and severe DES, respectively. The factors significantly correlated with OSDI scores were age and duration of wearing protective glasses, while the duration of wearing protective glasses may be a protective factor of dry eye symptoms.Our study showed that most of the doctors and nurses worked at the front-line of combating COVID-19 did not experience DES, while the symptoms of those who experienced DES might be improved by wearing protective glasses.
