Department of Communications and New Media, National University of Singapore.
This study applies protection motivation theory (PMT) to the COVID-19 contact-tracing context by including privacy concerns, collective efficacy, and a mediator (fear of COVID-19) and tests it in the US and South Korea. The study uses a structural equation modeling (SEM) approach and a sample of 418 Americans and 444 South Koreans. According to the results, fear was positively associated with adoption intentions in the US sample but not in the Korean sample.

Even at trace concentrations, micropollutants, including pesticides and pharmaceuticals, pose considerable ecological risks, and the increasing presence of synthetic chemical substances in aquatic systems has emerged as a growing concern. Moreover, limited machine-learning (ML) approaches exist for analyzing environmental data, and the increasing complexity of ML models has made it challenging to understand predictor-outcome relationships. In particular, understanding complex interactions among multiple variables remains challenging.

Background: Trace elements are the important components that play a crucial role in various functions of the human body at cellular and molecular levels. Considering the role of the trace elements in precancerous and cancerous conditions, estimation of their levels in these conditions could aid in understanding the disease process and progression. The purpose of this study is to determine the alteration in salivary electrolyte concentration of oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC) patients to correlate the variations with the severity and biological behaviour.

Article Synopsis
- - The MITRA-PRO registry shows that evaluating residual mitral regurgitation (MR) using 3D-Vena Contracta Area (VCA) is key for predicting patient survival after mitral valve repairs (TEER).
- - A study of 823 patients found that lower levels of residual MR (measured by 3D-VCA) correlate with reduced 1-year mortality, establishing 0.07 cm as a critical threshold for patient survival post-procedure.
- - The findings suggest that 3D-VCA is an effective tool for assessing MR during TEER, with lower residual MR levels associated with better survival outcomes.
Factors driving the acceptance of COVID-19 pandemic mobile contact tracing apps: The influence of security and privacy concerns.

The acceptance of COVID-19 mobile contact tracing apps (MCTA) is crucial to curb the spread of the virus and decrease the number of infections. However, the security and privacy concerns (SPC) of COVID-19 MCTA have been called into question. Thus this paper examines the drivers of the acceptance of the COVID-19 pandemic MCTA under the auspices of the influence of SPC from the Chinese perspective based on the modified Unified Theory of Acceptance and Usage of Technology (UTAUT) model.
