The year 2020 has concluded. This year was marked by a deep crisis in all the fields of society, caused by the pandemic of the covid 19. At a global level the editorial industry was impacted by the consequences of such a harmful illness. Nevertheless, for the academic community of the University of Holguín and for all those researchers involved in the processes of our online magazine, the editorial work didn’t stop, and the articles of its four numbers could be published. Today we go into in a new year that which we hope could be more favorable and it gives us with many expectations.

This first issue that opens our editorial work in the year 2021, offers a varied diversity of topics related to the pedagogic, technical and natural sciences. All of the articles portray the results of research projects and of thesis of doctor and master degrees.
