Relationship between psychological adaptability and work engagement of college teachers within smart teaching environments: the mediating role of digital information literacy self-efficacy.

Introduction: Integrating the Internet and traditional teaching has enriched teaching resources and methods and introduced many advanced digital media. The smart teaching process is influenced by teachers' psychological adaptability, which can be affected by teachers' work engagement. However, the relationship between the two has not received sufficient attention in the literature. This study aims to analyze the relationship between college teachers' psychological adaptability and work engagement in a smart teaching environment. Methods: Applying structural equation modeling (SEM) to a sample of 373 front-line teachers, this study focuses on the mediating effect of digital information literacy self-efficacy on the relationship between teachers' psychological adaptability and work engagement. Results: The results show that the four dimensions of college teachers' psychological adaptability strongly influence work engagement and digital information literacy self-efficacy. In particular, teachers' psychological adaptability and work engagement are positively correlated; teachers' self-efficacy can positively affect the three dimensions of their work engagement, and teachers' psychological adaptability can positively affect their digital information literacy self-efficacy. Conclusion: The above results can serve as a basis for the development and improvement of the training of college teachers and the implementation of smart teaching. The study findings highlight the importance of training teachers on information technology teaching and implementing measures to enhance teachers' digital information literacy self-efficacy. Training should focus on the knowledge and skills of teachers using information technology teaching and increase the practical links of teachers using information technology teaching.

Negative Bias or Positive Deficiency, or Both? The Relationship Between Individual Authenticity and Depression Among Preschool Teachers: The Sequential Mediation Effects of Mindfulness and Self-Alienation.

Objective: Depression has become a topic of widespread concern around the world, and teachers' depression has also had an important impact on the healthy development of education. However, there are differences in the cognitive theory of depression and positive psychology about the mechanism of depression. This study attempts to verify the related viewpoints of the two viewpoints through empirical research. Methods: Three hundred and twenty eight preschool teachers were measured with authenticity scale, five facet mindfulness questionnaire, center for epidemiologic studies depression scale, and general alienation scale. Results: Individual authenticity negatively predicted depression. Mindfulness can mediate the relationship between individual authenticity and depression. Self-alienation mediates the relationship between individual authenticity and depression. In addition, mindfulness and self-alienation played a sequential mediating role between individual authenticity and depression. Conclusion: Mindfulness and self-alienation play a sequential mediating role between individual authenticity and depression. This study not only confirms the relevant theoretical viewpoints of positive psychology on depression, but also believes that individual depression is not only affected by one's own negative bias but also by one's own positive factors. At the same time, the individual's own positive factors will affect the negative factors. This perspective will provide new literature references to existing relevant theories about depression. In addition, this study will also provide literature reference for early childhood education practice.

Structure design and mechanical performance analysis of three kinds of bioresorbable poly-lactic acid (PLA) stents.

Vascular stent implantation has become an important choice for the treatment of severe cardiovascular and cerebrovascular blockage. Rational design is vital to ensure the mechanical properties of the vascular stents, which are important both to the implantation and service as for clinical treatment of coronary heart disease. Therefore we proposed a wholly new non-uniform honeycomb stent E and compared with an inverted honeycomb-like shaped stent F and a honeycomb-like shaped stent G. To evaluate their properties, a finite element method (FEM) was used to simulate the implantation process (crimp, crimp recoil, expand, and expand recoil) of these three different kinds of stents. Results showed that the stent E exhibits better mechanical behaviour than the other two stents F and G as far as radial strength and axial shortening performances and that the distribution of equivalent stress among the stent E is more uniform than that among the other two stents F and G. After that, a three-point bending method was used to study the bending flexibility of these three vascular stents. Stent E shows high bending stiffness compared with stents F and G due to the existence of additional support bridges in its structure. This study can be helpful to the rational design of optimizable PLA stents for its practical clinical performance and therefore possibly improve the prognosis of patients.

The relationship between trait mindfulness and subjective wellbeing of kindergarten teachers: The sequential mediating role of emotional intelligence and self-efficacy.

This study explored the relationship between emotional intelligence and self-efficacy in trait mindfulness and subjective wellbeing. In this study, 323 Chinese kindergarten teachers were measured using the Five Facet Mindfulness Questionnaire, Emotional Intelligence Scale, General Self-efficacy Scale, and Subjective Wellbeing Scale. The study found that subjective wellbeing can be predicted directly from trait mindfulness (ß = 0.257, p < 0.001). Emotional intelligence could mediate the relationship between trait mindfulness and subjective wellbeing (ß = 0.165, p = 0.006). Self-efficacy could mediate the relationship between trait mindfulness and subjective wellbeing (ß = 0.078, p = 0.032). In addition, emotional intelligence and self-efficacy played a sequential mediating role between trait mindfulness and subjective wellbeing (ß = 0.072, p = 0.005). This study revealed the relationship between kindergarten teachers' trait mindfulness and subjective wellbeing through structural equation modeling and understood its role path, enriching the research on the Chinese preschool teachers in the field, and providing a literature reference for the international community to understand the Chinese kindergarten teachers. At the same time, the study also has some limitations, such as the use of a cross-sectional design method, a relatively single method, and the impact of COVID-19. However, we believe that this study will further enrich the research literature on the relationship between trait mindfulness and subjective wellbeing of Chinese kindergarten teachers.

[Research Progress of Biodegradable Vascular Stent].

Biodegradable vascular stents have better biocompatibility than drug-eluting stents. The blood vessels are rebuilt and degraded after normal physiological functions are restored. Due to it will not stay in the body for a long time and the patients don't need taking anti-rejection drugs all the time, it becomes the focus of attention in the treatment of coronary heart disease. This article introduced the development history of biodegradable stents and reviewed the research status of several different materials of vascular stents (animals or humans) in vivo and pointed out the existing problems. And it also predicted the research direction of biodegradable vascular stents.
