Ergonomic Factors That Impact Job Satisfaction and Occupational Health during the SARS-CoV-2 Pandemic Based on a Structural Equation Model: A Cross-Sectional Exploratory Analysis of University Workers.

This paper presents a structural equation model to determine the job satisfaction and occupational health impacts concerning organizational and physical ergonomics, using (as a study) objective unionized workers from the University of Sonora, South Campus, as an educational enterprise, during the SARS-CoV-2 pandemic. The above is a key element of an organizational sustainability framework. In fact, there exists a knowledge gap about the relationship between diverse ergonomic factors, job satisfaction, and occupational health, in the educational institution's context. The method used was a stratified sample of workers to which a job satisfaction-occupational health questionnaire was applied, consisting of 31 items with three-dimensional variables. As a result, the overall Cronbach's Alpha coefficient was determined, 0.9028, which is considered adequate to guarantee reliability (i.e., very high magnitude). Therefore, after the structural equation model, only 12 items presented a strong correlation, with a good model fit of 0.036 based on the root mean square error of approximation, 1.09 degrees of freedom for the chi-square, 0.9 for the goodness of fit index, and a confidence level of 95%. Organizational and physical factors have positive impacts on job satisfaction with factor loads of 0.37 and 0.53, respectively, and p-values of 0.016 and 0.000, respectively. The constructs related to occupational health that are considered less important by the workers were also determined, which would imply a mitigation strategy. The results contribute to the body of knowledge concerning the ergonomic dimensions mentioned and support organizational sustainability improvements in educational institutions and other sectors.

Physical Ergonomics Analysis for use of Non- Contact Infrared Thermometer Gun

Living in the "new-normal"world, the non-contact infrared temperature checks is expected to remain until such time that the treatment and vaccine against COVID-19 becomes available worldwide. Changing the mindset of the people is also a huge factor to consider in order to feel comfortable again without wearing a mask or conducting such pre-cautions. This paper aims to identify the relationship of the health and environmental factors to the discomfort that the person conducting the checks experience. The case study was done using the data gathered in the interviews, surveys, Cornell Musculoskeletal Discomfort Questionnaires (CMDQ), conducted Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) analysis. Minitab 18 was used to derived the correlation between the age, height, shifts, number of guests checked, RULA and REBA score to the discomfort experienced by the participants, using statistical analysis. This study will provide simple ideas that should help improve the staff welfare while performing the monotonous task. One of its objectives is to provide information on how to reduce the discomfort. It is also hoped that this study can serve as a reference in resolving similar tasks that promotes Musculoskeletal Disorders (MSDs). It aims to open up ideas on reducing the risks related to other new activities that are being performed in relation to this pandemic. © 2021 ACM.
