Practical and theoretical guidelines for research training in the Popular University ofe Cesar
(2020) Mendez Sanchez, Andrea Marcela; Gordon Hernández, Yimi; Vidal Tovar, Carlos Ramón
Abstract The purpose of this research is to propose practical and theoretical guidelines for strengthening research training in the Popular University of Cesar, Valledupar. Research training is understood as the practical and theoretical process that leads to the initial development of skills and abilities that allow the students of each academic program to structure research competencies. To achieve this, a methodological framework identified with the discipline is necessary, as well as the use of multiple strategies that can facilitate the teaching-learning process, and the acquisition of practical knowledge, related to the real problems of their environment. A descriptive, applied, documentary and field research was therefore carried out. A population of 138 teachers and 18 academic programs were involved, using a document review matrix to gather the necessary information about groups, research seedbeds, lines of research and degree options; postgraduate training, intellectual production and registration in the CvLAC of teachers responsible for research training; and the research contents, academic credits, and strategies used by teachers. The matrixes were submitted to content validity process carried out by five experts, while the data analysis was performed through the content analysis. Some of the results obtained suggested that the academic programs of the University require improving the strategies used to promote research training such as groups, research seedbeds, lines of research and degree options; as well as strengthening the curricula, the strategies used and the teachers responsible for research training. Keywords: research training, guidelines, academic programs, strategies
Analysis the application of logistics processes in the bakery sector of MSMEs in Valledupar
(2020) Gordon Hernández, Yimi; Vidal Tovar, Carlos Ramón; Valle Fuentes, Harold; Gordon Araujo, Juan Pablo
Abstract The adult population, who searches for foods that are beneficial to health, is the predominant consumer of the growing Colombian bakery sector, thus posing a challenge for it in order to generate a high-quality product. The purpose of this research was to analyze the application of logistics processes in the bakery sector of MSMEs in Valledupar, reviewing aspects such as the diagnosis of the current situation regarding logistics in the company, followed by an analysis of production costs, and the management of demand and purchase forecasts in the different MSMEs in the city. Ballou (2004), Castellanos (2015), Guerrero (2017), Mora & Martinez (2010), Saldarriaga (2014), Eslava (2019), among others, were used as references. It was conducted as an applied, non experimental, field, descriptive and cross-sectional research. The population consisted of 30 MSMEs from the bakery sector. The reliability of the instrument was determined with Cronbach's alpha, resulting in 0.919; while the significance was calculated using the Anova analysis, resulting in 0.000. This indicates that there are differences between the means of the macroprocesses and microprocesses dimensions. Furthermore, with the post-hoc Tukey test, the first major differences in the logistics of inventories showed that in the case of the indicator of logistics cost management and the second dimension, the use of raw materials has greater differences with the performance of the machines, demonstrating the great weaknesses that the bakery sector presents in the application of logistics processes. Keywords: Logistics processes, bakery sector, Valledupar MSMEs

Previous conceptual knowledge in engineering students for the solution of ordinary differential equations
(2020) Montaño Santamaría, W.E.; Suarez Galvis, F; Vengoechea Orozco, J.l.; Vidal Tovar, C.R.; Severiche Sierra, C.A.; Gordon Hernández, Y.
Abstract Conceptual knowledge for the solution of ordinary differential equationsin engineering students was identified. It is a quasi-experimental research applied to the educational sciences and technologies, descriptive in nature, using a quantitative approach. The population corresponded to one hundred and ninety (190) students of both sexes enrolled in the first semester of engineering at the ITSA University Institution, located in the city of Barranquilla and Soledad (Colombia), The sample consisted of fifty-three (53) students. The application of the instrument was carried out in sections corresponding to the evaluations of the first partial, second exam and final evaluation. In the instrument, the responses were classified as, leave it blank, it does not do it well, it does it fairly well and Yes it does. The finding indicates that students have a good command of preconceptions. As mathematics articulates the use of these preconceptions or integrates all the knowledge they have acquired around their career performance is not the most expected, this is probably because the cycles in students are not continuous. Keywords: Previous concepts, Differential equations, Mathematics education, University students, Pre-knowledge.

(2020) Gordon Hernández, Yimi; Vidal Tovar, Carlos; López Villalba, Stefany; Barrios Lara, Verónica
Abstract The general purpose of this research is to carry out a study for the optimization of the distribution chain in the process of production and marketing of certified organic powdered panela, in ASOSEYNEKUN, an association of productive indigenous families of the Sierra Nevada de Santa Marta, based in the theoretical postulates of Castellanos (2015), Mora (2008), Ballou (2004), Palella & Martins (2012), Hernández (2010), among others. The research methodology is explanatory, with a non- experimental, transactional and field design. Of the total of 170 cane producers affiliated with the association, a representative sample of 118 was analyzed, of which 10% was used to measure reliability through Cronbach's alpha (0.924). The results obtained with the instrument, validated by 10 experts, showed that there are differences between the results obtained (significance of 0.0000) with the Anova technique, and, with Tukey's post hoc, it was identified that there is a great difference in the first dimension between provisioning and storage indicators and between order processing and transport in the second dimension, order processing, it has a great difference with transport, concluding that there is poor knowledge in the management of its productive and commercial chain. Thus, actions that lead to an optimization of the Association’s distribution chain must be implemented, since weaknesses were evident in indicators, such as the systematization of orders, the commercial relationship between the other services provided, the outsourcing of physical distribution services and, finally, a poor flow of information between the areas in charge, which becomes one of its main problems for the optimal production and marketing of its products.

Conventional and advanced exergoeconomic indicators of a nitric acid production plant concerning the cooling temperature in compression Train’s intermediate stages
(2021) Buelvas Hernandez, Ana; Fajardo, Juan Gabriel; Barreto, Deybis; Carrillo Caballero, Gaylord Enrique; Cardenas Escorcia, Yulineth; Vidal Tovar, Carlos Ramon; Gordon Hernandez, Yimi
Abstract In the refining and petrochemical industrial sector, large amounts of energy are used, so using the concept of exergy allows a rational use of this resource. In the different exergy and exer goeconomics studies applied in petrochemical plants, parameters of interest have been deter mined to evaluate the thermal efficiency, the potential for process improvement, the irreversibilities produced by the interaction between the components of the system and the operation of each one, and the energy costs associated with each of these irreversibilities. This paper presents an advanced exergy analysis and an exergy-economic analysis applied to a nitric acid production plant with an installed capacity of 350 metric tons per day, whose operating principle is based on the Ostwald method, and both the behavior of endogenous exergy destruction and the behavior of exogenous, avoidable and unavoidable exergy destruction are studied, exogenous, avoidable and unavoidable exergy destruction and the associated exergy costs in each of the heat transfer equipment and reactive equipment that make up the plant, about the cooling temperature in the intermediate stages of the compression train are studied using a mathematical model. The chemical reactions involved in the production process are the points of interest in the research of this work. Some of the results show that 54 % of the total exergy destruction can be recovered by intervening in the components. On the other hand, in the Cat alytic Converter (CONV), it is convenient to consider the investment costs to reduce the exergy destruction costs. Similarly, in the Tail Gas Heater (TGH), it is beneficial to reduce the total in vestment to improve the process economics. On the other hand, the cost of exergy destruction of the plant resulted in 770.77 USD/h. In addition, it could be determined that the interactions between the components significantly affect the investment costs.

Había una vez… En la literatura infantil colombiana
(2021) Cifuentes Alvarez, Johana; Méndez Sánchez, Andrea Marcela; Méndez Sánchez, Diana Verónica; Montenegro de la Hoz, Nellys Esther
Cuando se habla de la historia de la literatura infantil colombiana es común asociarla exclusivamente a la producción del poeta bogotano Rafael Pombo (1883 – 1912); sin embargo, estudios más actuales, como El Aura Juguetona. Antología infantil ilustrada de la prensa de los siglos XIX y XX, llevado a cabo por investigadores de la Universidad Nacional de Colombia en 2018, han permitido reconocer otras obras y otros autores, como “El tigre y el conejo” de José Manuel Marroquín (51), “El mono y el gato” de Ricardo Carrasquilla (53), “Los funerales de un pajarito” de José Joaquín Ortiz (56), entre otras que enriquecen la perspectiva sobre la historia de este género en el país. Otros textos de esta índole que hemos podido rastrear son los escritos por Soledad Acosta de Samper (1883 - 1913), tales como “El mono” (1878), “El gato” (1879) ambos publicados en la revista La Mujer, y “Algo sobre astronomía” (1893) publicado en Álbum de los niños. Estas publicaciones revelan que la literatura dirigida a público infantil en el siglo XIX, en Colombia, no se limita a Rafael Pombo; en ese sentido, en el presente documento nos proponemos examinar un conjunto de textos de la autoría de Soledad Acosta de Samper, que permita reconocer, apreciar, y proponer un lugar para esta producción en el panorama de la literatura infantil colombiana. Palabras clave: Soledad Acosta de Samper, literatura infantil, Colombia, siglo XIX Abstract It is common to associate the history of Colombian children’s literature exclusively with texts written by the poet Rafael Pombo (1883 - 1912). However, current studies, such as “El Aura Juguetona. Antología infantil ilustrada de la prensa de los siglos XIX y XX”, carried out by researchers from Universidad Nacional de Colombia in 2018, have allowed the recognition of other works and other authors, such as “ El tigre y el conejo « by José Manuel Marroquín, “El mono y el gato” by Ricardo Carrasquilla, “Los funerales de un pajarito” by José Joaquín Ortiz, among others that enrich the perspective on the history of this genre in this country. Other texts of this nature that we have been able to trace are those written by Soledad Acosta de Samper (1883 - 1913), such as “El mono” (1878), “El gato” (1879) both published in the magazine “La Mujer”, and “Algo sobre astronomía”(1893) published in the newspaper “Álbum de los niños”. These publications reveal that the literature aimed at children in the 19th century, in Colombia, is not limited to Rafael Pombo. In this sense, in this document we propose to examine a set of texts authored by Soledad Acosta de Samper, which allows us to recognize, appreciate, and propose a place for this production in the panorama of Colombian children’s literature. Keywords: Soledad Acosta de Samper, children’s literature, Colombia, 19th century.

The new subjectivities: The role of the school in digitalized environments
(2023) López Barrios, Andrés Felipe; Fuentes Rodríguez, Ana Paola; Ardila Navarro Alexander; Arroyo Martínez Jhonny Javier
Summary Easy acces to media has led to the constant consumption of information through electronic devices, raising questions about the awareness and purpose behind this consumption, especially in children. The pandemic changed educational and social dynamics, giving rise to a hybridization between face to face and virtual. Participation in digital media has transformed the way children relate, learn, and construct subjectivities. School and teachers must adapt to these new realities and foster critical thinking and transmedia skills in students. Keywords: Information consumption, Media, Pandemic, Education
Sensory Considerations Generated by Biochemical Changes during the Fermentation of the Cocoa Almond
(2023) Vidal Tovar, Carlos Ramón; Gordon Hernández, Yimi; Parra Ditta, Clarivel; Vides Redondo, Adalberto José; Pérez Rojas, Yimmis Arturo; Daza Aranda, Alejandra Sofía
Abstract Cocoa is a crop of great economic importance all over the world, it is from this that the main raw material for the production of chocolate and other confectionery products is obtained, as well as other by-products such as pasta, butter, cocoa powder and liquor. Fermentation is carried out during the post-harvest of cocoa, it is the most important operation in the cocoa benefit, there the sensory attributes and physicochemical and biochemical quality characteristics of the cocoa almond are defined. This work presents an analysis of the changes in the physicochemical and biochemical characteristics of the cocoa almond generated by the effect of the fermentation process that determine the components of the sui generis flavor and aroma of chocolate. For the above, a bibliographic review of publications made between 2000 and 2021 was carried out. Present in the Scopus, Science Direct,Springer, ResearchGate, SciELO, Dialnet and Redalyc databases. The keywords used as search criteria in English and Spanish were: cocoa, cocoa beans, cocoa bean fermentation, chemical quality of cocoa. 200 documents were collected including review articles, research articles, mainly master's and doctoral theses and technical manuals. The reviewed publications report significant information about the microorganisms involved in cocoa fermentation, effects of fermentation on the pH of the cocoa bean, the physicochemical characteristics, the content of organic acids, the content of fat, sugars and proteins of the cocoa bean; the content of polyphenols and methylxanthines and the volatile compounds of the cocoa bean. Among the main conclusions are that the pH of the grain affects the biochemical reactions that form the flavor components such as free amino acids and peptides, among others. The total fat remains stable during fermentation, the sugar content of cocoa beans is affected by the fermentation process. The amount of proteins decreases during the fermentation time for all evaluated hybrids. During fermentation, the concentration of polyphenols is reduced because they are oxidized and polymerized to insoluble tannins of high molecular weight, this is why the bitter and astringent taste is reduced. The fermentation process and the varieties influence the volatile compounds and also determine the aromatic quality of the cocoa. Keywords: cocoa, cocoa fermentation, cocoa bean, physicochemical characteristics, biochemical characteristics.
