Cognitive failures and hand/neck discomfort: Does smartphone addiction contribute?

Background: Due to the emergence of smartphone addiction, as a 21th century phenomenon, investigating its subsequent negative effects is essential.

Objective: The present study aims to test the predicting effect of smartphone addiction on musculoskeletal discomfort in hand/neck region as well as cognitive failures.

Methods: A cross-sectional study was designed in which 533 smartphone users (60.

The mediating role of sleep quality between pre-sleep portable media device use and nursing performance.

The prevalence of portable media device (PMD) use has proliferated, potentially causing serious problems, particularly in critical situations. The main aim of the present study was to investigate the relationship between pre-sleep PMD use and cognitive performance, as well as the mediating effects of sleep quality among nurses. A cross-sectional study was designed, with 200 registered nurses voluntarily participating.

Establishing forward mixing model to mass transfer overview in multi-impeller agitated column for rare Earth extraction process.

The current study develops comprehensive mass transfer models to optimize the rare earth extraction. A plug flow, axial dispersion, backflow, forward mixing-based mass transfer model was created and solved numerically using the fitting technique. The investigated process is a multi-impeller agitated column designed to provide proper contact between organic and aqueous phases to extract rare-earth ions.

A comparative investigation of machine learning algorithms for predicting safety signs comprehension based on socio-demographic factors and cognitive sign features.

This study examines whether the socio-demographic factors and cognitive sign features can be used for envisaging safety signs comprehensibility using predictive machine learning (ML) techniques. This study will determine the role of different machine learning components such as feature selection and classification to determine suitable factors for safety construction signs comprehensibility. A total of 2310 participants were requested to guess the meaning of 20 construction safety signs (four items for each of the mandatory, prohibition, emergency, warning, and firefighting signs) using the open-ended method.
