Current experiences at a global level are an inspiration for research in the academic field. There is much to learn, and society must carefully reflect on the moments lived in two years that for many have meant two centuries. Many difficulties remain to be resolved and a wide field to discover the unknown by medicine. With the difficulties that have arisen on a global scale because of COVID-19, health has been affected at the societal level; In addition to the consequences derived from the effects of the virus, the mental health of people was impacted with high repercussions at the social and family level, as well as the teaching processes at the different levels of education where many students abandoned their studies.

The nurse has an important role caring for the patient infected with the coronavirus disease (COVID- 19). It is an infectious disease caused by the SARS-CoV-2 virus. The virus can spread from the mouth or nose of an infected person in small liquid particles when they cough, sneeze, speak, sing, or breathe. These particles range from larger respiratory droplets to smaller aerosols. It is important to practice respiratory etiquette, for example coughing into a flexed elbow, and to stay home and self-isolate until you recover if you feel unwell. Most people infected with the virus will experience mild to moderate respiratory illness and will recover without requiring special treatment. Older people and people with underlying medical conditions such as cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop serious illnesses. The goal of the research is to propose the best way to prevent and slow down transmission is to be well informed about the disease and how the virus spreads. Protect yourself and others from infection by staying at least 1 meter away from others, wearing a well-fitting mask, and washing your hands or using an alcohol-based rub frequently.

Some reflections will be presented on diabetes mellitus, which is a very common chronic disease in daily life due to different causes where diet and sedentary lifestyle directly influence. Considering these analyzes, the proposal of this work is to ensure that readers are able to know, interpret, disseminate and in many cases recommend preventive measures that help improve the physical and mental health of readers, and citizens, with this it would be achieved the best quality of life in society. The disease flourishes when the pancreas does not secrete enough insulin or when the body does not use the insulin it produces effectively. The effect of uncontrolled diabetes is hyperglycemia or high blood glucose). Over time, this disease seriously damages many organs of the human body, mainly the nervous system and blood vessels. They achieve a healthy body and mind at the present time that humanity is engaged in eradicating the viruses that have affected the world population, which would provide a healthy development for humanity.

Humanity has been on its way accompanied by epidemics, as man has evolved, he has faced different problems that have affected most of society. In the last 50 years, more viruses have appeared that have affected different regions and multiple countries; but one of the most distributed worldwide is COVID-19. The objective is to offer some information related to this pandemic and its evolution in different countries. The bibliographic review method was used even though some bibliographies are very recent, but it has allowed us to know their behavior and follow-up. The results of the countries most affected by this pandemic are shown, where it could be said that Italy has increasingly affected all of them and some countries in Asia, the United States, Latin America, and the Caribbean have been the most affected.

Se expone un análisis vinculado a una de las alternativas energéticas sostenibles que en la actualidad se está adoptando con éxito a nivel mundial con el fin de lograr el mejoramiento de la calidad del servicio eléctrico, ahorrar recursos naturales, reducir las pérdidas y contribuir en la disminución de las emisiones de CO2 a la atmósfera. Se muestran los resultados de un estudio relacionado con el uso de una innovación tecnológica para mejorar la calidad del servicio eléctrico en una comunidad aislada, mediante la introducción de tecnología fotovoltaica conectada a la red de baja tensión de un grupo de 20 viviendas que fueron estudiadas. Se muestran los resultados del estudio de carga y consumo horario de energía de las viviendas y se despliega una metodología propia para el diseño de la tecnología fotovoltaica conectada a la red de baja tensión de las viviendas estudiadas; este tiene el potencial de evitar el consumo de energía de la red convencional y la posibilidad de mejorar la calidad del servicio eléctrico, al tiempo que se reducen el monto de la factura eléctrica y las pérdidas.

Renewable sources are closely linked to the natural conditions of each region and locality, their availability is very varied from one site to another, being important the evaluation of the potential of these resources, in order to determine their best use under economically advantageous conditions. These constitute the equivalent fuel for the operation of the technologies that exploit them, their quantity and quality; It also depends on the energy performance and reliability of the technology systems that employ them. An analysis of the importance of the determination of the regionalization of the RES is presented, showing the energy, economic and environmental impacts that can be estimated in specific regions and localities. For this, the studies carried out in the province of La Habana and in the municipality of San Luis in the province of Santiago de Cuba are presented as practical examples of a territorial planning, considering the conditions of each locality. The results are shown using the Geographic Information System (GIS). The contribution obtained allows the preliminary knowledge of the renewable potential (solar, wind, water and biomass), which can be considered for a regionalization of the planning with renewable energy sources, in order to reach the goals of sustainable development, based on the search Of energy solutions at the Community level. Keywords IntroductionDe la misma forma que se trazan políticas regionales para resolver los problemas de investigación, desarrollo e innovación relacionados con el uso de recursos energéticos renovables en América Latina y El Caribe (ALC) [1], también se trabaja en función de disminuir los riesgos naturales, salvar la biodiversidad y mejorar las condiciones de vida de las comunidades que todavía no están conectadas a las redes eléctricas. En el plano nacional se requiere el trazado de estrategias que permitan la solución de problemas, de forma integral en regiones y zonas determinadas.Las políticas trazadas por los países bajos, Alemania, Dinamarca, Australia, Japón, España y China, que han ido incorporando a su matriz energética un porciento importante de fuentes renovables de energía (FRE), han desarrollado proyectos de evaluación y estudios de potenciales renovables desde el nivel local, municipios, provincias y regiones, que le ha permitido determinar la zonificación del empleo más adecuado de estos recursos, considerando criterios de la calidad de los potenciales, en función de alcanzar una elevada eficiencia de la gestión energética, apostando por las garantías que puedan ofrecer las mejores condiciones de la disponibilidad del recurso, para asegurar una gestión económica viable y ventajosa.En América del Norte existen programas de desarrollo de las FRE, Estados Unidos y Canadá proponen soluciones ventajosas. Ya se comenta la posibilidad de lograr en el uso de la penetración con fuentes renovables de energía a un 100 % renovable [2]. Estos países proponen reducir las emisiones de gas de efecto invernadero utilizando el potencial de viento, ag...

Geographic Information System for Sustainable Energy Development (SIGDES). It is the system which contains geo-referenced data that leads to the knowledge about several potentials of renewable energy sources in the province of Manabí. The objective of providing this information is proposed in a system that promotes the educational research and projects for business development with a territorial vision of sustainability that can make possible the change of energy matrix. The system allows the user to use the information contained in the database, focusing on the solution of energy problems in the community and leads to local sustainable development.
