Preschool education optimization based on mobile edge computing under COVID-19

AUTHOR(S)
Hongzhi Wei; Yuqian Yang; Zhijian Liu

Published: January 2022   Journal: Expert Systems
The COVID-19 pandemic has brought profound changes in people's live and work. It has also accelerated the development of education from traditional model to online model, which is particularly important in preschool education. Preschoolers communicate with teachers through online video, so how to provide high quality and low latency online teaching has become a new challenge. In cloud computing, users offload computing tasks to the cloud to meet the high computing demands of their devices, but cloud-based solutions have led to huge bandwidth usage and unpredictable latency. In order to solve this problem, mobile edge computing (MEC) deploys the server at the edge of the network to provide the service with close range and low latency. In task scheduling, edge computing (EC) devices have rational thinking, and they are unwilling to collaborate with MEC server to perform tasks due to their selfishness. Therefore, it is necessary to design an effective incentive mechanism to encourage the collaboration of EC devices.

Published: January 2022   Journal: Journal of Psychosomatic Research

This study aims to evaluate the association between mask wearing practice and the risk of anxiety symptoms during the COVID-19 epidemic among Chinese students aged 12–18 years old. Totally, 386,432 junior and senior high school students were recruited using a cluster sampling method across three cities of Henan Province in China during February 4–12, 2020. Mask wearing practice was defined according to its type and the behavior exhibited in relation to wearing a mask. Presence of anxiety symptoms was determined by Generalized Anxiety Disorder tool (GAD-7). Multiple logistic regression was performed to estimate the association between mask wearing and anxiety symptoms.

Published: January 2022   Journal: Journal of Affective Disorders

This study examines the patterns and predictors of depression and anxiety trajectories among adolescents during COVID-19 lockdown in China. A total of 35,516 college students were followed from the pandemic outbreak period, initial remission period, and control period. Participants completed the Patient Heath Questionnaire, Generalized Anxiety Disorder Scale, Perceived Social Support Scale, the Simplified Coping Style Questionnaire, and APGAR-family scale. Distinct patterns of depression and anxiety trajectories were established through grouping participants based on time-varying changes of the cut-off score. Multivariate logistic regressions were used to examine predictors for trajectory membership.

Published: December 2021   Journal: Human Vaccines & Immunotherapeutics
This study aims to determine the intention of Chinese parents to vaccinate their children against SARS-CoV-2. Secondly, preferences for foreign- or domestically made COVID-19 vaccines were also explored. A nationwide, cross-sectional, self-administered online survey based on the Health Belief Model (HBM) and new vaccine concerns was used. Participants were eligible if they were residents of China with children aged 12 years old or younger. A total of 2,026 parents responded to the survey. Half reported a probable intent (50.7%) and 26.9% reported a definite intent. The results of the data analysis of partial least squares structural equation modeling (PLS-SEM) found that perceived cost barriers (B = −0.210, p < .001) and new vaccine concerns (B = −0.201, p < .001) had major effects in vaccination intent. Important constructs of vaccine concerns that predict vaccination intent were efficacy (B = 0.898, p < .001), followed by safety (B = 0.861, p < .001), side-effect (B = 0.806, p < .001) and faulty/fake vaccine (B = 0.579, p < .001).

Published: December 2021   Journal: The Family Journal
This study aims to describe children's mental health conditions in the time of COVID-19 and its associations with the risk factor (media exposure) and the protective factor (family resilience) during COVID-19. The study took place from February 13th to February 29th, 2020, at the peak of the outbreak all across China. In total 441 children (M  =  11.83 years old, SD  =  0.79) from Jiangxi province, China, filled out online surveys. The results showed that children's rates of depression were relatively high and post-traumatic stress disorder (PTSD) rates were low. Based on the results of multiple linear regression analyses, family resilience was negatively associated with children's mental health issues including depression, anxiety, PTSD, and poor sleep quality counting the effects of children's age, gender, and media exposure. Children's media exposure to COVID-related news reports did not significantly contribute to the total variance of children's mental health symptoms.

After COVID-19 appeared in China in December 2019, the mental health of adolescents, as a vulnerable group in public health emergencies, was negatively affected by the epidemic and the unprecedented prevention and control measures. The purpose of this study was to investigate the factor structure and psychometric properties of the Posttraumatic Stress Disorder (PTSD) Checklist (PCL) among Chinese adolescents. A total of 915 participants completed the PTSD. Confirmatory factor analyses (CFAs) and multi-group CFAs were used to test the factor structure and psychometric properties of PTSD.
Caregivers’ intentions to COVID-19 vaccination for their children in China: a cross-sectional survey

AUTHOR(S)
Huangyufei Feng; He Zhu; Haijun Zhang (et al.)

Published: November 2021   Journal: Human Vaccines & Immunotherapeutics
Recently, COVID-19 infection in children has increased. Although most countries have not approved the COVID-19 vaccine for children, it is likely that they will do so. There is a clear need to explore caregivers’ intentions and to understand potential hesitancy as means to inform vaccination policies. This study found a relatively high caregivers’ intention rate to have their children vaccinated against COVID-19, and caregivers’ intentions to be vaccinated themselves was associated with their own decision to have their children vaccinated. In this study, older age, lower education level, belief that the COVID-19 vaccine was safe and effective, and residence in Hubei province were associated with increased odds of caregivers intending to have their children vaccinated. Policy makers should address caregivers’ concerns about vaccine safety and encourage caregivers themselves to get vaccinated before they decide to have their children vaccinated.
