ABSTRACT
The events caused by the COVID-19 pandemic forced educators to transition to a fully online education system. Therefore, the implementation of project-based learning (PBL) in education is not an easy task. However, since PBL offers students many learning benefits, the aim of this paper is to conduct a bibliometric analysis to measure the performance of using PBL in engineering courses. Two computer tools have been used to carry out the analysis: a) Scopus as a performance analysis tool and b) SciMAT to carry out the bibliometric analysis of content from scientific maps. The results show that the topic with the highest performance for the period 2000-2015 corresponds to the topic of engineering educators, with a h-index of 19, 157 linked articles and, 4815 citations. However, the transition to digital teaching is shown in the period 2016-2021, where e-learning systems represent a cross-cutting theme in the field of research. Therefore, the close relationship of the PBL methodology with engineering educators and the transition to virtual education is shown. However, it requires the integration of e-learning platforms. This is closely related to the driving topics shown in the strategic map for the 2016-2021 period, such as: ensuring the quality of teamwork;properly monitor learning experiences;enhance the focus on engineering design;and work on planning the design of the curriculum, to involve all the activities and evaluations of the educational goals. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.

ABSTRACT
The CO VID-19 pandemic has had serious consequences in various sectors such as health, economy, and Education. The students of the initial, primary, and secondary level, as well as university in the month of March 2020 went to a total confinement and this generated changes in the way of providing education. In universities, the curriculum had to be adapted to the situation, which is why the semiotics course that studies the behavior of signs, sought to promote disruptive innovation in the works presented by students. This research reflects the themes addressed by the students and their creative capacity. © 2022 Latin American and Caribbean Consortium of Engineering Institutions. All rights reserved.
ABSTRACT
The ent repreneurship project sapplied in the Communicat ion course are developed based on the individual ent repreneurship approach, evidencing efficacy, crit ical at titude, creativity, collaborative work and social responsibilit y in it sdifferent product ions. The study met hodology is qualitative, cross-sect ional and exploratory. Among the main findings, it was det ermined that the students have shown a willingness for collaborative work in the development of their project s based on research and writing in order to provide a solut ion to various social problems with the support of ICT. However, they faced some limitations such as reading comprehension, identification of sources, and handling of citations and references. Finally, it was ident ified that there are factors that favor research such as access to web search engines and search engines and permanent feedback. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.

ABSTRACT
Avoiding a resurgence of the COVID-19 virus is essential to minimize any risk of new infections in the population. Therefore, the objective of this research is to design an automatic temperature measurement and disinfection system as part of the biosafety protocols, to serve highly recurrent public and private establishments. The device is made up of two systems: the body temperature meter and the alcohol or disinfectant gel sprayer. The device design is done in Autodesk Inventor software, and the graphical interface of the system is developed in MATLAB software. The results determine that the temperature measurement data is displayed through a graphical interface, allowing, or preventing entry through an oscillating barrier. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.

ABSTRACT
The COVID-19 pandemic has devastated various industries, and electric power is no exception. Therefore, a significant change in human activities has been generated, causing economic disruption and energy shortages. In this sense, the objective of the study focuses on proposing a model for evaluating the Autonomy of Solar Photovoltaic (SPV) Microgrids (AMR) with battery energy storage systems (BESS). For the analysis of the AMR, the daily records (hours) of energy consumption of a house and the local daily solar irradiation data were used. Considering the zero-target approach, the Microgrid (MR) and the BESS should supply as much SPV power as possible at all times based on demand. The results show that the AMR model manages to perform the evaluation consistently;and that the AMR depends on the daily profile of the residential energy demand, the stochastic availability of the solar energy resource and the optimization of the BESS. Therefore, the AMR evaluation model is essential to establish the best possible scenario of the autonomous, optimal and stable operationofMRs in residentialapplications. © 2022 Latin American and Caribbean Consortium of Engineering Institutions.
