The Impact of Vaccination on the Likelihood of COVID-19 Infection.

The current study investigates COVID-19 infection likelihood using data from 5,819 respondents in Vietnam and Indonesia (December 10, 2022, to March 27, 2023) through binary logistic regressions. Descriptive statistics highlight the significance of vaccination status, with almost half of unvaccinated respondents contracting the infection. The second vaccine dose showed the lowest infection percentages, suggesting a potential dose-dependent effect.

Exploring the Sub-nanoscale Structure of Cobalt Molybdenum Sulfide and the Role of a Cobalt Promoter in Catalytic Hydrogen Evolution.

Cobalt-promoted molybdenum sulfide (CoMoS) is known as a promising catalyst for H evolution reaction and hydrogen desulfurization reaction. This material exhibits superior catalytic activity as compared to its pristine molybdenum sulfide counterpart. However, revealing the actual structure of cobalt-promoted molybdenum sulfide as well as the plausible contribution of a cobalt promoter is still challenging, especially when the material has an amorphous nature.

The Willingness of Parents to Vaccinate Their Children Aged from Five to under Twelve Years with COVID-19 Vaccines between February and March 2022 in Vietnam.

The current study used data surveyed with 5357 parents/guardians (parents would be used to represent both 'parents' and 'guardians' hereafter) between February and March 2022 in Vietnam to examine their willingness to vaccinate their children with current COVID-19 vaccines. It applied the multinomial logistic regression model to examine the association between the willingness of parents and selected influential factors. In addition, the reasons that made parent hesitant or unwilling to vaccinate their children were investigated.

Electronic Device Use before Bedtime and Sleep Quality among University Students.

Using electronic devices before bedtime impacts sleep quality and has become a major public health issue. This study aims to investigate the associations between electronic devices (EDs) use before bedtime and sleep quality in Vietnamese university students. A total of 369 university students from three departments were recruited.
