Manufacturing of a mechanical respirator valve in the context of e-learning methodology

This work shows a project-based learning methodology (PBL) compatible with e-learning within the Manufacturing Process Engineering course. Students of the Bachelor's Degree in Mechanical Engineering were proposed to carry out a project to design the manufacturing process to make a valve of a mechanical respirator for medical use. This activity was carried out during the confinement period due to the COVID 19 pandemic and this valve was chosen due to the high demand for respirators as a result of the pandemic at that time. Once the activity was applied, the evaluation process was applied and, finally, a questionnaire was passed on to students to obtain data on acceptance and perception of the activity. The results showed adequate acceptance in terms of learning, utility, and scalability. © 2021 ACM.

Based-on simulation training on ventilation calculation for the reduction of occupational risk of SARS-CoV-2 infection

This paper addresses a new learning methodological approach compatible with e-learning and m-learning for undergraduate engineering students to learn the ventilation requirements for the prevention of SARS-CoV-2 virus infection in the workplace and to develop the critical sense to design ventilation systems in accordance with the standards that minimize the biological risk. Thus, a learning activity based on a simulation of infection risks is proposed in which three different initial ventilation requirements hypotheses were considered to calculate the necessary ventilation in the workplace. Subsequently, a simulation was carried out to obtain the probability of contagion in each of them and, in this way, to obtain information to make adequate decisions and improve critical thinking in the context of industrial hygiene. © 2021 ACM.
