To offer better treatment for a COVID-19 patient, preferable medicine selection has become a challenging task for most of the medical practitioners as there is no such proven information regarding it. This article proposes a decision-making approach for preferable medicine selection using picture fuzzy set (PFS), Dempster-Shafer (D-S) theory of evidence and grey relational analysis (GRA). PFS is an extended version of the intuitionistic fuzzy set, where in addition to membership and non-membership grade, neutral and refusal membership grades are used to solve uncertain real-life problems more efficiently. Hence, we attempt to use it in this article to solve the mentioned problem. Previously, researchers considered the neutral membership grade of the PFS similar to the other two membership values (positive and negative) as applied to the decision-making method. In this study, we explore that neutral membership grade can be associated with probabilistic uncertainty which is measured using D-S theory of evidence and FUSH operation is applied for the aggregation purpose. selleck chemical Then GRA is used to measure the performance among the set of parameters which are in conflict and contradiction with each other. In this process, we propose an alternative group decision-making approach by the evidence of the neutral membership grade which is measured by the D-S theory and the conflict and contradiction among the criteria are managed by GRA. Finally, the proposed approach is demonstrated to solve the COVID-19 medicine selection problem.With the rapid advancement of China's "Internet plus Education" plan, "Internet plus Education" has become a research hotspot. The outbreak of COVID-19 pandemic has brought great opportunities, tests and inspections for online education. All schools earnestly implemented the relevant requirements of the Ministry of Education and leverage the strengths of the Internet to ensure that "suspension of classes and non-stop teaching". Taking a middle school in the west part of China as an example, the online survey was conducted to investigate its live broadcast teaching. The independent sample test and one-way analysis of variance were used to statistically analyze the differences among the students' genders, grades, home location, type of device used and parental companionship. Finally, the implications were put forward to provide a reference for live teaching practice.The study explores the school transformation process as evidenced by the opinions of head teachers. The main goal of the research was to present a content analysis study of the Polish educational environment on the basis of primary and secondary head teachers' views on the risks and perspectives brought by the global Covid-2019 lockdown. The conceptual framework was based on the theoretical perspective (the cognitive and affective processes in multimedia learning, the theory of motivation, and goal setting) as well as the model of the school as a learning organization and the assumptions of Emergency Remote Teaching. The categorized interviews with the head teachers were conducted using a categorized interview questionnaire and the respondents considered various categories problems within educational practice related to the functioning of schools during the pandemic. The selection of study participants was deliberate using the snowball sampling method, 18 head teachers participated in this study. The research conducted allowed the specification of the different areas of influence of Emergency Remote Teaching on the transformation of the school as a learning organization (e.g. the functioning of the school in mutual internal and external network cooperation, the dissemination and extending of communication areas using information technologies, the strengthening of the network interaction through information technologies, and other areas). The paper contains numerous recommendations that can improve the school's functioning in the future, based on the experience gained during Emergency Remote Teaching. These experiences can accelerate the organizational and didactic development of the school as a learning organization.The unprecedented situation of the COVID-19 pandemic has caused the closure of universities worldwide and has forced the transition to online learning. This exceptional context compels us to understand students' experience with online learning. Previous literature identifies relevant factors that intervene in the online education experience and can affect students' academic development. One of the main concerns is the students' mental health, given the lockdown restrictions under which classes have been conducted. Furthermore, the impact of the prolonged lockdown and the pandemic fatigue on university students and their academic experience is still unclear. This study delves into engineering undergraduate students' online education experience during the COVID-19 pandemic and its emotional impact across time. With this aim, a questionnaire was distributed to second, third, and fourth-year engineering undergraduate students at two time points, approximately six months apart. The results show significant differences in students' connection with other students and teachers, workspace conditions, and boredom between time points. Besides, the findings indicate significant correlations between academic development and quality of online classes, adaptation of the course, workspace conditions, and connection with other students and teachers, and also between students' emotions and connection with other students and teachers. Finally, the study identifies best practices carried out during online teaching that will be of value for future courses and engineering education beyond the pandemic situation, amongst which those related to effective communication with teachers stand out.Social support and strain have been linked with many health outcomes. However, less is known about whether these psychosocial factors are associated with Type 2 diabetes risk. This study uses the Midlife in the United States (MIDUS) dataset to examine the relationship between social support and strain from friends, family members, and spouse/partners and blood hemoglobin A1c levels in married/cohabiting adults who have not been diagnosed with diabetes. In addition, health locus of control is examined as a possible mediator. The study's findings suggest that support from friends is negatively associated with HbA1c levels, indicating a relationship between better glycemic control and social support from friends, and an indirect association for spouse/partner support. A direct effect for internal health locus of control was also found.
