The employed methodology integrates advanced algorithms and mobile devices with GPS for real-time monitoring of the vehicle fleet. The results demonstrate a significant improvement in operational efficiency and control of distribution routes.

The urban areas with the highest urban and population growth, such as the city of Guayaquil, are the main consumers of energy and therefore require greater consumption of fossil fuels for electricity generation. In some countries, large-scale progress is being made in the energy transition from fossil fuels to sustainable energy sources; however, the construction of new infrastructure is necessary. Given this scenario, electricity generation through renewable energy sources is the most viable option for the energy sustainability of cities, even being the best alternative until local governments invest in the construction of the necessary infrastructure. By means of the bibliometric analysis of journals with greater influence in the SCImago indicator, a business model for the development of sustainable urban energies in the city of Guayaquil is proposed; reaching the conclusion that the proposed business model is oriented to a premium service with aggregates in the final product.

The fourth Industrial Revolution refers to a new paradigm based on technology, where information andcommunication systems are largely used to improve productivity in an intelligent way. The objective ofthis article was to analyze the teaching competencies necessary for the effective integration of the Internetof Things (IoT) and Artificial Intelligence (AI) in the context of Industry 4.0 in the Faculty of ComputerScience of the Technical University of Manabí. This research presents a quantitative approach, because thesurvey technique was used through the application of an online questionnaire directed to a total populationof 63 teachers currently working in the Faculty of Computer Science. In addition, the bibliographic methodwas integrated with a non-experimental design. The results showed that 45% of teachers do not have a verybroad knowledge of IoT and AI. Based on these results, a pedagogical proposal is presented for the trainingof teachers with a view to improving their skills in areas such as IoT and AI.

The essential oil of Eucalyptus globulus, recognized for its antioxidant properties, was extracted through steam distillation from fresh and dry leaves collected in Crucita, Portoviejo, Ecuador. The samples were processed at temperatures of 40 °C, 50 °C, and 60 °C to evaluate their yield and antioxidant capacity. The essential oil yield ranged from 0.47% to 1.16%, being higher in fresh leaves. Antioxidant capacity was determined using two methods based on free radical scavenging, obtaining values between 92.8 and 112 micrograms per milliliter in the first method, and between 75.1 and 408 micrograms per milliliter in the second, expressed as trolox equivalents. The results showed significant antioxidant activity, although lower than that reported in previous studies. It is concluded that fresh leaves produce higher yields, and optimizing the extraction conditions is recommended to enhance their antioxidant potential.

Like many other developing countries, Cuba also faces the unavoidable and peremptory need to transform the traditional concept of operation of its ports that implies significant changes in the already traditional model for its management. The lack of methodological support to carry out this strategic transformation in the main Cuban territorial ports, led to the design of an alternative and complementary, as well as pertinent, flexible and robust methodological instrument that can guide the complex process of transforming them into integrated customer-oriented logistics platforms in Cuban conditions. Based on a situational diagnosis of context, the phases and stages of strategic planning were adapted to this singular process, taking the port of Cienfuegos as referent. The exposed result focuses on the foundation of the designed methodological instrument for its application in Cuban territorial ports that allow its management as a critical node of dynamic integration of the port logistics chains, associated with a 3rd generation port.

Every day, process management becomes more relevant in organizations due to the benefits it provides for the planning, control and improvement of their mission. This research was developed at the UEB Production of the Center's Petroleum Drilling and Extraction Company. The proposed study objective is: to analyze production planning in the UEB. The production system was characterized and classified, the behavior of demand was forecast and techniques and tools were used, such as the proportional method, used to calculate production capacity and the tabular method, used to prepare the master production plan. It was demonstrated that the UEB has sufficient capacity to meet the production plan. Likewise, it was proven that the institution has good performance dynamics, good reliability and satisfactory stability, but; continuity, proportionality and rhythmicity can be improved.  

La presente investigación tuvo como objetivo proponer mejoras de la calidad en la producción de bloques de balsa, basado en el estudio del proceso de encolado. La misma tuvo un enfoque cuantitativo, descriptivo, no experimental y transversal, con la realización de análisis estadísticos en el encolado de dichos bloques en una empresa dedicada a la exportación. Se obtuvo que el gramaje/ gramatura fue una de las principales causas de no conformidad, identificando como causal esencial el deficiente control de los parámetros de temperatura y humedad ambientales. El control estadístico de procesos y la regularidad estadística de las características de calidad son esenciales para garantizar la calidad de los bloques de balsa, futuras investigaciones deben profundizar en la estandarización de los parámetros de temperatura y humedad para la optimización del proceso de encolado.
