Messaging to Reduce Booster Hesitancy among the Fully Vaccinated.

Vaccine hesitancy was a serious problem in the United States throughout the COVID-19 pandemic, due in part to the reduction in public trust in science that accompanied the pandemic. Now we are facing a new, similar but more extensive problem: booster hesitancy. Even fewer Americans are current on the mRNA booster.

Organic waste derived bioethanol supply chain network: Multiobjective snapshot model with a real-Korea case study.

Bioethanol, a promising biofuel gasoline additive, was recently produced by a new technology using acetic acid derived from organic waste. This study develops a multiobjective mathematical model with two competing minimization objectives: economy and environmental impact. The formulation is based on a mixed integer linear programming approach.

Health and happiness of older Korean women participating in dance activities.

This study aimed to determine the health and happiness of older women participating in dance activities using the phenomenological analysis method. The study used snowball sampling to recruit eight participants among older women participating in a 3-month dance program in Korea, starting from March 2019. Data were collected through in-depth interviews and participatory observations, after which the gathered raw data were codified, systematically arranged, and analysed.

Understanding the travel decision-making processes of COVID-19-vaccinated South Korean travelers.

During the COVID-19 pandemic, many countries allowed only the vaccinated to travel abroad, and some still continue with these restrictions. This study aimed to determine the factors associated with the intention to travel abroad during this pandemic. An online survey was conducted with 270 vaccinated Korean participants.

COVID-19: Risk perception, risk communication, and behavioral intentions.

Critical to limiting the spread of Coronavirus disease 2019 (COVID-19) and future pandemics is compliance with behavioral recommendations such as mask wearing and social distancing. Compliance may depend upon understanding the seriousness of the health consequences and the likelihood they will occur. However, the statistics that speak to these issues in an ongoing pandemic are complex and may be misunderstood.

Mesoporous platinum electrodes for amperometric determination of sugars with anion exchange chromatography.

A simple amperometric detection (AD) method based on mesoporous platinum (Pt) electrodes has been developed for the determination of sugars (glucose, fructose, and sucrose) with high-performance anion-exchange chromatography (HPAEC). The amperometric detection is based on the direct oxidation of sugars on mesoporous Pt films formed on a gold electrode. The mesoporous Pt electrode (roughness factor of 243) sensitively responded to glucose, fructose, and sucrose in 80 mM sodium hydroxide solution as an alkaline mobile-phase for HPAEC.
