ABSTRACT
Thanks to the principles and technologies made available by Industry 4.0, the authors conceptualized and modeled a new strategy, capable of making an effective contribution to the problem of limiting contagion from Covid19 today, and tomorrow from any possible other type virus, bacteria or pathogen agent introduced by subjects who, although unaware of being vectors, develop the infection only after their access to the places of stay (Hotel, office, Infrastructure, etc.) where they go to reside. The key point of the strategy is a 4.0 thermoscanner, created by the authors, which is positioned in appropriately chosen locations of the settlement and an innovative method of disinfection of the same implemented by means of UV-C rays and Ozone in the gaseous state, produced by a machine, also conceptualized and developed by the authors, capable of reproducing the Chapman Cycle with the associated advantages. Therefore, it is operated an absolute disinfection based on a reversible cycle Oxygen-Ozone-Oxygen, with a prompt re-habitability of the treated rooms, with minimal treatment costs and without the use of expensive and unhealthy chemicals or wet water vapor (incompatible with paper and electronics). This technology was described in the paper “Sanitizing of Confined Spaces Using Gaseous Ozone Produced by 4.0 Machines” presented by the authors to the WCE 2021 IAENG Congress and awarded with the “Best Paper Award of the 2021 International Conference of Systems Biology and Bioengineering”. In the presence of a Person with a fever, the thermoscanner automatically launches an alert to the site Safety officers, who confine him to an isolated place and make the Health Institutions intervene and take it over. © 2022, AIDI - Italian Association of Industrial Operations Professors.

ABSTRACT
In March 2020, due to the pandemic linked to the COVID-19 virus spreading, all in-person teaching activities planned at the University of Salerno were suspended. This sudden suspension has forced the academic world to rethink in a short time the didactics and to modify teaching styles and approaches, especially in those courses in which laboratory activities were planned. This article will be presented the experiences made in the Computer Networks and Protocols for the Internet of Things (IoT) course. The course includes a significant laboratory component where students must put into practice what they learned during the theoretical lessons. In particular, the laboratory exercises involve using specific equipment and devices that can build digital ecosystems for the control and management of well-defined operational contexts difficult to reproduce virtually. Therefore, to give continuity to the didactic activity, it was necessary to redesign the entire exercise system preserving the original educational objectives.
ABSTRACT
A fundamental aspect of the fight against the Coronavirus and against any other virus, is represented by the sanitization of the sites and objects contained therein. This operation is normally carried out using mixtures of ozone and steam and it is certainly effective but also limited due the damages that the vapor can cause to rooms and objects. The following paper introduce machines able to overcome this issue thanks to innovative systems based on the principles of Engineering 4.0. Those systems reproduce the Chapman cycle in the to-be sanitized environments which allows producing ozone in a gaseous state, in the proper quantity and for the time necessary for sanitization. At the end of the operation, the ozone will be converted back into oxygen, leaving the environment re-habitable by humans and pets in a short time. The operation has low costs and times and guarantees positive results. This is therefore a real revolution to be considered today against the COVID-19. © 2021 Newswood Limited. All rights reserved.
