Trends in study topics related to quality of life in Industry 4.0: A bibliometric analysis.

Background: The use of new technologies boosted Industry 4.0, making processes more sophisticated and considering the interaction between physical production systems and workers. But these new technologies also intervene in the worker's quality of life (QoL), that is, we need to know if the industry of the future is changing the scenario of the present.

A method for predicting the Actual Percentage of Dissatisfied (APD) through a simple proposition of thermal comfort zones in a working environment.

Background: Over the last few decades, there has been a concern to improve the quality of indoor work environments and increase energy efficiency as people spend much of their time in such settings.

Objective: This study analyzed a group of women developing sedentary activities to determine the Actual Percentage of Dissatisfied (APD) in the environment, considering that all people who voted any value other than zero on the seven-point scale are deemed dissatisfied.

Methods: After this analysis, using the probit regression model, hot and cold air temperature curves were plotted so as to determine in which situation the number of people dissatisfied with the environment is minimal.

Thermal suitability in industrial environment: a case study in a metallurgical industry.

Background: This article presents the results of an investigation into the thermal aspect of workplaces of the metallurgical branch of furniture manufacturing, looking for the number of dissatisfied people in the environment.

Objectives: This study aims to analyze the thermal suitability of a metallurgical industrial environment, from four interpretations of vote +1/-1 (slightly warm or slightly cool) on the thermal sensation range, reported by workers.

Methods: The methodological approach consists of quantitative research and a literature review set for this work, composed of spreadsheets and statistical processing of data.
