This work shows the need to apply information and communication technologies (ICTs) with a Programming Logic Controller (PLC) to control humidity by remote monitoring in the refrigeration process of an agricultural industry located in the Mexicali Valley of northwestern Mexico, where large amounts of orange are grown in this region of the country. This industry there were automated electronic devices (AEDs) for humidity control in the refrigeration area to prevent the deterioration of this agricultural product, only that the AEDs installed inside the evaluated company, did not operate properly due to the presence of outdoor atmospheric pollution (hydrogen sulfide (H2S)) and oxide sulfur (SO2)), and extreme climates in summer and winter (variations of temperature and relative humidity (RH))in this area of the country, that had an negative effect in indoors environments, and damaged their electrical connections. The principal climatic variables are the temperature and relative humidity (RH). The humidity in the refrigerated room for the orange keep its nutritional and physiological conditions, had to be between 45% and 55%. As AED, did not function properly, the climate inside the agricultural industry was not controlled, causing low and high humidity levels. With indexes below 30% humidity in the refrigerated room, oranges dehydrated and began to wilt, in addition to losing weight that was considered as unfit products for marketing. And at levels greater than 60% humidity, in this agricultural product microorganisms formed and caused rot, considered as a defective product and in both cases causing economic losses. The PLC was used with a wireless system and installed in an isolated room that only specialized personnel could enter if necessary. This was done in this way, to avoid deterioration of their electrical connections and that they did not operate as the AEDs and had adequate humidity control, to constantly maintain adequate humidity in the refrigerated room and avoid the generation of defective products. The research was made out from 2018 to 2019.

Siendo de gran importancia el comprender las nuevas dinámicas empresariales a las que se vieron obligados a adaptarse ocasionadas por la pandemia Covid-19, la cual desestabilizó los diferentes sistemas socioeconómicos y en particular de las Mipymes, estas se vieron afectadas por el cese temporal de actividades, causando disminución en sus ingresos, esto generó la toma de decisiones encaminadas a atender los compromisos adquiridos mediante acciones que permitieron a su vez visibilizarse y posicionarse nuevamente en el mercado. El objetivo de este trabajo es identificar las estrategias del marketing digital implementadas por las Mipymes en particular del sector restaurantero en Mexicali, Baja California en tiempos de pandemia Covid-19. Se realizó una búsqueda documental y aplicación de un instrumento a 25 sujetos de estudio. En conclusión, se identificaron las estrategias de tipo organizacional como son la redirección de objetivos, la planificación y operativización de las MiPymes en como la implementación del marketing digital, mediante el uso de redes sociales Facebook e Instagram para visibilizarse y posicionarse generando un impacto positivo en el mercado actual.  Por lo que en la medida que los micro, pequeños y medianos empresarios restaurantero en Mexicali desarrollen procesos de gestión de las comunicaciones les será más fácil acceder a los nuevos canales de comercialización que la web ofrece a través de redes sociales, y plataformas estarán en contacto permanente con los clientes-consumidores generando novedosos sistemas que les permitan ser competitivos.

This work presents a way to optimize the manufacturing processes in a small biomedical industry considered in the micro-, small-, and medium-sized enterprises (SME) group and located in the Mexicali city, using a specialized software that act as design and test of a new model, being the COSIMIR (Cell Oriented Simulation of Industrial Robots) software. With this software was designed a new industrial process in a workstation separated of the main step of a manufacturing line, where are fabricated biomechanical knees pads. The process was made as a manual activity in a work station and had to be separated from the conveyor belt of the main activities, because where previously made by an automatized device that was failing continually and was delaying the delivery to the next steps of the manufacturing processes and to the customers as a final product fabricated in this industry. In this place of the company, an operation was made to organize the biomechanical knee in a plastic container with divisions and to be transported safe and quickly to other area by a conveyor belt with linear process flow. The investigation was conducted from 2018 to 2019.
