    (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.

    Biometrical Optimization System for Red Tilapia (Oreochromis sp.) through Image Processing in Growing Environments
    (2023) Vides Redondo, Adalberto José; Vidal Tovar, Carlos Ramón; Pérez Rojas,Yimmis Arturo; Parra Ditta, Clarivel; Gordon Hernandez, Yimi
    Abstract The costs of an aquaculture production process are affected by about 70% by the technical food management, in that sense, it is absolutely necessary to accurately establish the food rations throughout the cultivation cycle, making adjustments weekly, so the determination of biometric variables is required with the same periodicity. The objective of this research was to make possible an alternative for obtaining biometric information in an aquaculture production process, obviating harmful aspects, which occur in the development of traditional biometrics, where it is required to perform invasive procedures (partial fishing) that generate negative impacts on cultured organisms. In this sense, in the development of the present study, magnitudes of the specimens of red tilapia (Oreochromis sp) were determined, through the analysis of images obtained in culture environments at high densities, all this, using a software specially designed to measure the length of the specimens, managing to generate a lower impact on the fish. For the development of the software it became necessary to determine the events and sequences, thanks to unified modeling language diagrams - UML, in this specific case the use cases, sequence and entity relationship were used. Subsequently, each of the events and sequences determined in the UML were embodied in code, using the C# programming language and the Visual Studio (IDE) in its community version. On the other hand, the calibration of the system was carried out in three clearly defined phases: 1. selecting the image capture device, 2. support structure adjustment of the image capture equipment, and 3. calibration of the measurement software. Keywords: Red Tilapia, Biometrics, UML Diagrams, Use Cases, Entity Relationship.

    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.

    Determinantes de la intención de compra en línea a través del modelo UTAUT2: un análisis del riesgo percibido en los consumidores en línea
    (2025) Solano Mejía, Jhon Henrry; Méndez Sánchez, Andrea Marcela
    Objetivo: el objetivo del presente estudio fue analizar los factores determinantes en la intención de compras en línea en los consumidores del municipio de Valledupar, mediante la aplicación de la teoría UTAUT2 con la inclusión de la variable de riesgo percibido. Diseño/metodología: la metodología empleada fue de tipo explicativo, con un enfoque cuantitativo, y un diseño no experimental, transeccional y de campo. Los datos se recopilaron mediante un cuestionario en línea y se analizaron 387 encuestas de consumidores que habían comprado en línea al menos una vez. El análisis de los datos fue realizado a partir del modelamiento de ecuaciones estructurales (SEM), con la técnica multivariante de modelos de ecuaciones estructurales de mínimos cuadrados parciales (PLS-SEM). Resultados: la investigación evidenció que las variables expectativa de desempeño, expectativa de esfuerzo, motivación hedónica, valor del precio y hábito influyen en la intención de compras en línea; mientras que las variables influencia social, condiciones facilitadoras y riesgo percibido no alcanzaron a tener efecto en la intención. Conclusiones: las relaciones entre los constructos de la UTAUT2 tienden a variar según el contexto cultural; en este caso, la variable más significativa para la intención de compra en línea es el hábito, demostrando que cuanto más integrada esté la acción de comprar en línea en la rutina diaria, mayor será la intención de hacerlo. Originalidad: el estudio aporta información sobre el comportamiento de los consumidores en e commerce, como también extiende el análisis de la intención de compra en línea a una población poco estudiada en este contexto. Palabras clave: UTAUT2, comercio electrónico, intención de compra en línea, riesgo percibido, comportamiento del consumidor. Highlights El riesgo percibido influye poco en la intención de compra de usuarios experimentados. Una experiencia de compra ágil y eficiente resulta clave para captar y fidelizar clientes. El modelo UTAUT2 adaptado al comercio en línea colombiano presenta un buen ajuste. Una experiencia agradable en plataformas virtuales fomenta la intención de compra. Abstract Objective: This study analyzes the key determinants of online purchase intention among consumers in Valledupar (Colombia), using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and incorporating perceived risk as an additional variable. Design/Methodology: The study follows an explanatory approach with a quantitative methodology and a non-experimental, cross-sectional, and field-based design. Data were collected through an online questionnaire, with a final sample of 387 consumers who had made at least one online purchase. Structural Equation Modeling (SEM) was applied with the Partial Least Squares (PLS-SEM)multivariate technique for data analysis. Findings: The findings indicate that performance expectancy, effort expectancy, hedonic motivation, price value, and habit influence online purchase intention. However, social influence, facilitating conditions, and perceived risk were found to have no measurable effect on purchase intention. Conclusions: The relationships between UTAUT2 constructs tend to vary depending on cultural context. In this study, habit emerged as the most influential factor in online purchase intention, suggesting that the more seamlessly online purchase is integrated into daily routines, the greater the intention to continue doing so. Originality: This paper contributes to the understanding of consumer behavior in e-commerce and extends the analysis of online purchase intention in a population that has been relatively underexplored in this context. Keywords: UTAUT2, e-commerce, online purchase intention, perceived risk, customer behavior. Highlights Perceived risk has minimal influence on purchase intention among experienced users. A seamless and efficient shopping experience is crucial for customer acquisition and retention. The UTAUT2 model, adapted to Colombian e-commerce, demonstrates strong applicability. A positive user experience on virtual platforms enhances purchase intention.

    Diagnóstico situacional para potenciar la internacionalización de las mipymes del sector agroindustrial de Valledupar, Colombia
    (2024) Escobar Argumedo, Madimis; Méndez Sánchez, Andrea Marcela
    Objetivo: diagnosticar la situación actual de las mipymes del sector agroindustrial de Valledupar con el fin de potenciar su internacionalización. Metodología: se aplicó una metodología con enfoque cuantitativo, de tipo descriptivo, y un diseño no experimental, transeccional y de campo. Como muestra para el estudio, se seleccionaron cuarenta mipymes del sector agroindustrial, empleando el método de muestreo aleatorio estratificado a través de la afijación uniforme. Se utilizó, además, la técnica de encuesta y, como instrumento, un cuestionario. Resultados: se realizó un análisis detallado basado en el modelo PESTEL y en las matrices de Evaluación de Factores Externos (EFE) y de Evaluación de Factores Internos (IFE), y se propusieron estrategias utilizando la matriz de Fortalezas, Oportunidades, Debilidades y Amenazas (FODA). Según la matriz de evaluación de factores externos (MEFE), las mipymes se favorecen de las oportunidades que les brinda el entorno y evitan las amenazas externas. Sin embargo, la matriz de evaluación de factores internos (MEFI) reveló un resultado desfavorable: las mipymes no aprovechan las ventajas competitivas internas para mejorar su desempeño. Conclusiones: las mipymes agroindustriales de Valledupar enfrentan desafíos significativos en su internacionalización, como la falta de empleados con competencias en otros idiomas y experiencia en comercio internacional. Sin embargo, estas empresas tienen potencial al contar con colaboradores suficientes, eficiencia en generación de utilidades y acceso a acuerdos comerciales y plataformas digitales, lo cual facilita la expansión a mercados internacionales. Originalidad: a diferencia de estudios previos, la presente investigación se centra en identificar no solo las barreras tradicionales, sino también en proponer soluciones y estrategias innovadoras adaptadas a necesidades específicas de las empresas. Un análisis minucioso del contexto actual en el que operan las mipymes del sector agroindustrial permite identificar esas necesidades. Palabras clave: diagnóstico situacional, internacionalización agroindustrial, competitividad empresarial, mipymes, agroindustria. Highlights Las mipymes agroindustriales de Valledupar se enfrentan a diversos desafíos en su proceso de internacionalización. Las empresas del sector agroindustrial de Valledupar deben mejorar sus sistemas logísticos y superar barreras técnicas y fitosanitarias para gestionar operaciones diarias y cumplir con normativas internacionales. La falta de alianzas estratégicas y estudios de mercado impide a las mipymes aprovechar acuerdos comerciales y plataformas digitales para acceder a nuevos clientes internacionales. Las plataformas digitales y tiendas en línea permiten a las mipymes agroindustriales de Valledupar contactar nuevos clientes y vender productos sin necesidad de presencia física en otros países. Abstract Objective: To analyze the current situation of Micro, Small, and Medium-sized Enterprises (MSMEs) in the agro-industrial sector in Valledupar (Colombia) to help enhance their internationalization efforts. Design/Methodology: This study employed a quantitative, descriptive methodology; a non experimental, cross-sectional design; and field research. The sample included 40 MSMEs from said agro-industrial sector, which were selected using stratified random sampling with uniform allocation. Data were collected through a survey, employing a questionnaire. Findings: A detailed analysis was conducted based on the PESTEL model and the External Factor Evaluation (EFE) and Internal Factor Evaluation (IFE) matrices. Strategies were proposed using the Strengths, Weaknesses, Opportunities, and Threats (SWOT) matrix. The EFE matrix indicated that these MSMEs take advantage of the opportunities provided by the environment and evade external threats. However, the IFE matrix revealed that they do not use their internal competitive advantages to improve performance. Conclusions: Agro-industrial MSMEs in Valledupar face significant challenges in their internationalization efforts, such as a lack of employees with foreign language skills and experience in international trade. Nevertheless, these companies show potential because they have sufficient staff, efficient profit generation, and access to trade agreements and digital platforms, which facilitate their expansion into international markets. Originality: Unlike previous research, this study focuses not only on identifying traditional barriers but also on proposing innovative solutions and strategies tailored to the specific needs of MSMEs. Said needs were identified in a thorough analysis of the current context where these agro-industrial MSMEs operate. Keywords: situational analysis, agro-industrial internationalization, business competitiveness, MSMEs, agro-industry. Highlights Agro-industrial MSMEs in Valledupar face several challenges in their internationalization process. These companies should improve their logistics systems and overcome technical and phytosanitary barriers to manage daily operations and comply with international regulations. Their lack of strategic alliances and market research prevents these MSMEs from utilizing trade agreements and digital platforms to reach new international clients.

Abstract Introduction: The starting point was the need to improve reading comprehension levels among Sociology students, given the low results obtained in previous assessments. Objectives: Students were evaluated through a workshop to compare results from two rubrics, one focused on reading comprehension and the other on critical thinking. Methodology: A case study was conducted with six students from the Sociology of Education course, based on the article "El currículo: una reflexión crítica" by Luis Malagón Plata. A second assessment was conducted by a group of professors. The course instructor then applied a rubric to assess the development of critical thinking. Results: A low level of reading comprehension and textual production was recorded, but there was better development of critical thinking. Conclusions: It is concluded that changes are necessary in the development of critical thinking due to a shift from text-based learning to one centered on thought, through dialogical didactics. Keywords: Case study; Reading comprehension; Digitalization; Critical thinking; Dialogical teaching.

    Evaluation of a silage Produced by Mixture of Residues of Cassava (Manihot Esculenta ), Potato (Solanum Tuberosum), Eggplant (Solanum Melongena) And Watermelon (Citrullus Lanatus), Generated in Supermarkets
    (2023) Gordon Hernández, Yimi; Vidal Tovar, Carlos; Pérez Rojas, Yimmis Arturo; Parra Ditta, Clarivel; Vides Redondo, Adalberto José
    Abstract This paper evaluates the physical, chemical and microbiological composition of silage obtained from mixtures of plant residues. The research was experimental with a quantitative approach, the data obtained from the response variables were analyzed using statistical tools for the subsequent interpretation of the data. For the execution of the experiment, plant residues of potatoes, cassava, eggplant and watermelon discarded in supermarkets in the city of Valledupar were used. For the production of silage, a completely random experimental design was applied with four treatments and three repetitions. The best treatment was selected through the analysis of variance (ANOVA) and comparison of means through the Tukey test. Three of the four alternatives for the production of silage are viable since they carry the process in a correct way because the pH values given suggest that there is an optimal production of lactic acid bacteria. The tests carried out comply with adequate characteristics in treatments two, three and four. Treatments containing the highest percentage of cassava showed the best values in fiber, carbohydrates and protein. While the silages that contained in greater proportion the potato were the richest in moisture. Keywords: Silage, Vegetable Waste, Animal Feed, Supermarkets, Fermentation.
