Musculoskeletal disorders prediagnosis by infrared thermography in CNC machinery operators: Regression models approaches.

Background: Musculoskeletal System Disorders (MSDs) are a group of injuries that represent common occupational diseases and should be evaluated for prevention purposes because an increase has been observed due to the repetitive movements performed in the industry. This research was carried out in a manufacturing industry where metal parts are manufactured, and workers experience back and wrist pain.

Objective: To prediagnose Musculoskeletal System Disorders (MSDs) and examine the relationship between temperature, demographic, and physiological factors in workers through predictive models, contributing to MSD prevention.

Exploring the Theory of Employee Planned Behavior: Job Satisfaction as a Key to Organizational Performance.

This article introduces a significant advancement with the "Theory of Employee Planned Behavior" (TEPB), a novel extension of the well-established Theory of Planned Behavior (TPB). The TEPB uniquely positions job satisfaction as a central determinant in driving organizational performance. Using data from county-level government institutions in the United States, this research offers a nuanced exploration into how employee satisfaction influences organizational commitment and citizenship behaviors, which, in turn, substantially impact organizational performance.

Psychosocial risk factors identification in Mexican workers and RGIII validation.

Background: Since 2018, NOM-035-STPS-2018 has been applied in Mexico, focused on measuring psychosocial risk factors (PRFs) in workers and the Reference Guide III (RGIII) has been presented, however, research focused on its validation has been scarce, in very specific sectors and with small samples.

Objective: Determine the levels of PRFs of five work centers and reliability and validity aspects of RGIII.

Method: The RGIII was applied to 1458 workers (806 women and 652 men) from five workplace in the industrial sector of Ensenada (Mexico), and the level of risk of the PRFs was analyzed, as well as their reliability and validity through Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).

Influence of Resilience on Burnout Syndrome of Faculty Professors.

This research aims to describe the relationship between resilience and burnout facing COVID-19 pandemics. The sample was = 831 lecturers and professors of a Mexican public university. This study is a quantitative, non-experimental, cross-sectional, explanatory, and ex post facto research using Structural Equations Modeling with latent variables under the partial least square's method technique.

Infrared thermal imaging monitoring on hands when performing repetitive tasks: An experimental study.

The monitoring of infrared thermal images is reported to analyze changes in skin temperature in the hand fingers when repetitive work is performed to know which finger has a greater risk of injury, besides, the recovery time is analyzed regarding the initial temperature and its relationship with age, sex, weight, height if practice sports, and Body Mass Index (BMI) per individual. For the above, an experimental test was carried out for 10 minutes on a repetitive operation that takes place in the telecommunications industry and 39 subjects participated in which an infrared thermal image of the dorsal and palmar part of both hands was taken in periods of 5 minutes after the 10-minute test has elapsed. The results show that none of the participants recovered their initial temperature after 10 minutes of the experimental test.

Quantitative Models for Prediction of Cumulative Trauma Disorders Applied to the Maquiladora Industry.

Temperature gradient changes on the surface of the skin or in the middle of the body are signs of a disease. The aim of this study is to develop quantitative models for the prediction of cumulative trauma disorders (CTDs) arising from highly repetitive activities, considering risk factors, such as age, gender, body mass index (BMI), blood pressure (BP), respiratory rate (RR), and heart rate, to prevent injuries in manufacturing factory operators. This research involved 19 individuals from the area of sanding and 14 individuals from the area of tolex in manufacturing factories who had their vital signs and somatometry taken, as well as thermal images of their hands in the dorsal and palmar areas; an evaluation by the OCRA method was also applied.

Burnout Syndrome in Police Officers and Its Relationship with Physical and Leisure Activities.

No previous studies in Mexico have been found that jointly analyze physical and leisure activities as variables related to mental health in police officers. This paper presents research on burnout in Mexican Police officers. The question it answers is: is there any association of burnout with physical and leisure activities and personal profile? A total of 276 police officers (87% men and 13% women) participated.

The resource-based reflective risk assessment model for understanding the quality of work life of nurses.

Background: There is a need to examine the psychological traits that impact the "personal quality of life" and "personal well-being" of caregivers in the workplace.

Purpose: This research proposes the resource-based reflective risk assessment model using a "at risk" framework to integrate mental health traits, producing a "portrait" of nursing quality of life and well-being.

Methods: Cross-sectional surveys on the quality of work life of nurses in Australia and Mexico were used to collect data.
