El presente proyecto de investigación pretende establecer herramientas de optimización, a través de una solución genérica que pueda ser utilizado en empresas de los sectores económicos, agropecuario y metalmecánico, proponiendo un algoritmo multiobjetivo a los modelos de transporte y asignación; buscando no solo minimizar costos sino tiempo de envíos de los productos utilizados en el sector agropecuario, y, maximizar la calidad del servicio prestado en los contratos realizados con los clientes, en la asignación de tareas para el cargo del soldador en la empresa metalmencánica. Por lo tanto, se tomaron como referencia datos estadísticos de las empresas objeto de investigación, respecto a la calidad del servicio y los tiempos de duración de los envíos a los diferentes almacenes. Así esto, el alcance del proyecto busca minimizar costos y tiempo, a su vez, maximizar la calidad del servicio prestado; aplicando el método inductivo, y, proponer un algoritmo multiobjetivo general. Para hallar el mínimo costo y la máxima calidad en la asignación de tareas al cargo de soldador en la empresa metalmecánica, y, el mínimo costo y tiempo en el transporte de los envíos de la empresa del sector agropecuario, se inició con la aplicación del método Húngaro, seguido, la generación de soluciones aleatorias para establecer jerarquías, con el fin de evitar repetición entre números, y obtener las soluciones tipo A, que componen las soluciones óptimas extremas o multiobjetivo. Por consiguiente, los resultados obtenidos indican que, para el sector metalmecánico se obtuvo una solución multiobjetivo conformado por un conjunto de 6 soluciones de costo y calidad en el servicio prestado y para el sector agropecuario, están dados por, un conjunto de 3 soluciones de costo y tiempo en el transporte de los envíos, a los cuales se les asignó una prioridad porcentual sobre los objetivos, con el fin de elegir una única solución de acuerdo a las necesidades indicadas por la empresa.

This article is intended to communicate to society a topic of our current interest such as the impact of social knowledge networks in globalization. We know initially that these social networks of knowledge are electronic platforms that help to interact in the continuous advance of sharing knowledge reciprocally, mainly regarding the collaborative work in the organizations and the great growth of these in the development of scientific knowledge. Therefore, this article aims to inform the globalized society and, particularly, the knowledge society in which we live today, the importance of the management of social networks of knowledge. In our daily lives and especially being these technological platforms of high impact for civilization current, learn how we can use them properly and get the best possible use of this virtual tool that we have at our fingertips, especially in regard to the technological, social, academic and work. Then we will know a little more about what are the social networks of knowledge, what they are made for and what is the purpose that these networks have for us now, expecting in the same way that we can get the best advantage of this tool.

The present article of reflection seeks to show how technology, especially the applications achieved through the HCI: Human Computer Interaction contributes to the strengthening of the teaching-learning process, to such an extent that some scholars even consider it as the emergence of a new pedagogy. Researchers in the field of HCI both observe the ways in which humans interact with computers and design technologies that let humans interact with computers in novel ways. As a field of research, human-computer interaction is situated at the intersection of computer science, behavioral sciences, design, media studies, and several other fields of study.With this purpose, some of the technological advances that we find today are portrayed at the expense of education and the way in which a technological era arises in the education of our country.

The strategic system of public transport that is being implemented in the city of Neiva will carry out infrastructure changes in the city, improve mobility, and contribute to the strengthening of civic culture. The inhabitants of the Commune One of the city of Neiva are the target population of the research. In order to characterize the population currently using the city's public transport system and identify the needs and behavior, the application of an instrument for collecting information (survey) is used. The model of civic culture will enable the inhabitants of the Commune One improve and strengthen their behavior citizen by applying different types of strategies, taking into account that culture is a dynamic process that requires time to achieve the awareness of the commune and work in welfare and the reduction of accidents, as well as ensure results in generations to come.

This research is intended to idenfify the process and optimum solvent for the extraction of sativa cannabis oil from the punto rojo and mango biche varieties. There are multiple techniques used for their extraction. Their key principle is the use of an extractor agent, which may be petroleum ether, ethyl alcohol / ethanol, water, among others. When in contact with the solid material, the extractor agent allows the solutes, that is, the phyto-cannabinoids, to be transferred to the solvent to be then separated. In this way the essential oils are obtained. The aims of the stuy are (1) to identify the existing processes for extraction of essential oils and the description of the different solvents; (2) determine the advantages and disadvantages of each of these; (3) make the selection of the most appropriate method; and (4) put it into practice and perform laboratory tests to determine the percentage of Tetrahydrocannabinol (THC) and Cannabidiol (CBD).
