Publicación Acceso abierto Análisis exergético de la generación de biogás a partir de biomasa residual en el departamento de Córdoba(2021-09-24) Guevara Pacheco, Ernesto Tercero; Mora Ospino, Rubén David; Bonilla Gracia, Samuel Iván; Bonilla Gracia, Samuel; Vega González, Taylor de la; Sofan Germán, StivenThe objective of this work was to provide an exergy analysis of biogas production from biomass, through a simulation of the anaerobic digestion process through the Aspen Plus program, theoretical data on biogas production could be obtained through the digestion process. A thermodynamic model was selected that is already included in the program called NRTL (Non-Random Two-Liquid model). Said method correlates and calculates on the basis of molar fractions and activity coefficients for different components, facilitating liquid vapor equilibrium. (Serrano, 2011). Biogas production represents a key process for the country's energetic variety, since it allows to reuse / reconvert industrial by-products or agro-industrial waste into a product that can be used in different energy-demanding sectors, after adequate cleaning and conditioning. Through the exergetic analysis, an efficiency of 55.2% was obtained in the process with a destruction of exergy of 3749.72034 kWPublicación Acceso abierto Análisis sobre el manejo de la seguridad y salud industrial en las empresas de hipermercado, frente al nuevo virus pandémico COVID 19 en Colombia durante el año 2020(2021-06-23) Aleán Guzmán, Juan Camilo; Gómez Cabrales, Yina AndreaIndustrial safety and health at work, manages to be a fundamental part of any company, so much so that it has been put to the test with what is currently being presented, in which the pandemic is involved due to of COVID 19, which reiterates the importance of saving, caring for and protecting the lives of internal customers, work personnel. Faced with this new situation that the human being is facing, new protection measures must be taken in this area, which calls attention to investigate, due to the fact that it is a totally new issue for society, where intervention is even seen of the government in all this commercial process that companies carry out. In this way, the various policies, measures, risk management, planning and emergency preparation that both a large and a small company should have taken for these extracurricular reasons will be analyzed, as the virus has brought, in which the environment of workers in the labor market during the coronavirus in Colombia, evaluating and comparing this aspect in industries of the marketing sector with a multi-format strategy in managing hypermarkets, supermarkets with a supply structure or productive chain, thus highlighting the importance that this entails this whole procedure.Publicación Acceso abierto Influencia del liderazgo y la duración de la jornada laboral sobre la productividad(2021-07-03) Luna Argumedo, Luis Fernando; Gómez Cabrales, Yina AndreaIn previous times the world could have had the conception that people were more productive by being the greater amount of time at the work place. In some countries there has been a change in mentality and it has been shown that the opposite is true, but in others, such as Colombia, people continue to be unproductive despite having one of the longest working weeks in the world. The question arises as to how much influence the length of the working day and leadership has on productivity. Based on an arduous bibliographic review, it was sought a qualitative relationship between these factors, taking into account research carried out around the world, strategies of multinational companies among others. Studies have shown that productivity and extended working hours are inversely proportional, demonstrating that more hours in the office do not mean more output. On the other hand, new strategies at the time of leading influence in the increases of productivity, like Google that presented an increase of 42% in the last years. In general, it could be seen that the extension of the working day and leadership have an influence on the productivity of people, but other parameters such as education, training, salary, etc. must also be taken into account.Publicación Acceso abierto Innovación frugal como estrategia para afrontar la crisis del COVID-19 en Colombia(2020-08-27) Muñoz Berrocal, Juan Fernando; Mercado Hoyos, Luis EnriqueThe situation in the country has changed abruptly as a result of the COVID-19 disease caused by the SARS-COV2 virus, starting as a topic corresponding to the national health service, the pandemic has generated devastating consequences in other axes of Colombian society. The economy, social and tourist activity, commerce and transport are some of the many sectors that have been affected after the implementation of necessary strategies to contain the spread of the virus. The figures of the economic and financial development of the country show evidence of these aforementioned ravages, and imply that the country will need to rethink its strategies to get afloat, to continue with its health and socioeconomic activity mainly. The shortage and the increasing difficulty in attending the needs of customers due to the closure of roads and preventive isolation (strategies for virus mitigation) have generated a growth in the BoP of the national economy, which means that some services and products are leaving out an increasing number of customers, such as transport, a sector that has had to reduce its capacities due to a mandatory distance between the people who use its systems, which is why it cannot serve the same number of users that normally attended. For all this and in the face of the need for intelligent maneuvers to manage the current crisis, frugal innovation is presented as the basis for creating an economic, commercial and social strategy in the country. Frugal innovations are answers to the problems, they are quality solutions that arise particularly in situations of scarcity, mainly in developing countries according to the needs of their BoP and it is thanks to these similarities with the current situation that the nation is going through, that it delves into the topic of frugal innovation in order to describe it and support its acceptance and implementation. VIII Frugal awareness and culture have proven to be crucial in developing frugal innovations, even on occasions when professional education was not present. The country has already taken its first steps in innovations of this type during the crisis, but to create a culture and awareness it is necessary to clarify everything related to frugal innovation, for this reason it is important to analyze in detail the properties that are inherent to these kinds of innovations.Publicación Acceso abierto Los juegos serios como metodología de enseñanza en la prevención de accidentes laborales: análisis en las unidades de producción agropecuaria(2021-08-15) Martínez Flórez, José Julián; Plaza Gómez, María TrinidadLos juegos serios son una herramienta de aprendizaje que ayuda a fortalecer áreas específicas, dependiendo del desarrollo del juego, existen diferentes aplicaciones de los juegos serios en la educación o en el desarrollo de habilidades, es por eso, que para esta investigación se hizo un análisis exhaustivo de documentos relacionados con los juegos serios y su influencia en el aprendizaje. Se hizo énfasis en juegos serios con desarrollos cognitivos, aplicados a la salud, a la seguridad y salud en el trabajo, entre otros.
