ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

Summary: Currently, agricultural activity is constantly threatened by the effects of climate change and radical expression of environmental factors as irregular rainfall distribution responsible for water availability and deficit. These factors generate water stress in productive systems, whose negative effect is reflected on morphological, physiological and biochemical aspects of vegetative growth. The use of biostimulants arises as a strategy to counteract this impact, improving crop efficiency in the use of resources and generating responses, as metabolite production, among other substances that mitigate the effects of oxidative stress. In this context, waxes, hydrogen peroxide (H2O2), salicylic acid (SA) and ALGAENZIMSMR were used on raspberry plants subjected to moderate water stress (-0. 8 MPa) to evaluate the fruit response in aspects of vegetative growth, physiological and biochemical quality. For the establishment, a completely randomized design was used with 5 treatments: Green Cover as 5 mL L-1, H2O2 10-4 M, salicylic acid 0.27 mM, ALGAENZIMSMR 7.5 mL L-1 and the control with 50% recovery of the transpired volume as well as water potential similar to the rest of plants and 4 replicates. The results showed that waxes, SA and algal extract increased the photosynthetic rate; the four treatments increased root length; waxes increased root height; and H2O2 increased root biomass. Compared to the control, higher levels of vitamin C and anthocyanins were produced in fruits - a very important aspect due to the functionality of these compounds in human health. Therefore, the use of these biostimulants are a very useful tool for crop management in environments with water restriction.

Resumen: En la actualidad la actividad agrícola se ve amenazada constantemente por los efectos del cambio climático y la expresión radical de los factores ambientales, como la irregularidad en la distribución pluvial responsable de la disponibilidad del agua y déficit, que genera estrés hídrico en los sistemas productivos, cuyo efecto negativo se refleja en aspectos de crecimiento vegetativo, morfológicos, fisiológicos y bioquímicos. El uso de bioestimulantes surge como estrategia para contrarrestar este impacto, mejorando la eficiencia de los cultivos en el uso de los recursos y generar respuestas, como la producción de metabolitos entre otras sustancias, que mitigan los efectos del estrés oxidativo. Bajo este contexto se planteó el uso de ceras, peróxido de hidrogeno (H2O2), ácido salicílico (AS) y algaenzims, sobre plantas de frambuesa sometidas a estrés hídrico moderado (-0.8 MPa) con el objetivo de evaluar la respuesta en aspectos de crecimiento vegetativo, fisiológicos y calidad bioquímica de frutos, para el establecimiento se empleó un diseño completamente al azar con 5 tratamientos: greencover as® 5 mL L-1, H2O2 10-4 M, ácido salicílico 0.27 mM, algaenzims® 7.5 mL L-1 y el control con recuperación del 50% del volumen transpirado y con potencial hídrico similar al resto de plantas y 4 repeticiones. Como resultados se obtuvo que las ceras, AS y el extracto de algas incrementaron la tasa fotosintética, los cuatro tratamientos aumentaron la longitud de raíces, las ceras la altura, y el H2O2 la biomasa de raíz. Por otro lado, en comparación con el control, se produjeron mayores niveles de vitamina C y antocianinas en frutos, un aspecto muy importante por la funcionalidad de estos compuestos en la salud humana. Por lo tanto, el uso de estos bioestimulantes se puede visualizar como una herramienta de gran utilidad para el manejo de cultivos en ambientes con restricción de agua.

Abstract In retail markets, analysis of perceived value in purchasing processes has been a topic of special interest as it focuses on perception of benefits beyond the product itself. In the face of such interest, an exhaustive bibliographical review was performed regarding its concept and components applied to retail dealers. The methodology is quantitative and cross-sectional, with a descriptive and explanative analysis through structural equation models to analyze the effect of dimensions in perceived value in the dependent variable of intent to purchase. Applied surveys on 390 recurring customers of retail dealers in Bogota. The results revealed that: functional value does have a positive effect on intent to purchase; and there is a relation between functional and symbolic value of purchase. The implications of management in the context of marketing are further discussed, focusing on functional value of a purchase. Actions related to quality, communication, employee training and customer service are recommended. These findings contribute to the literature on consumer behavior within the context of consumption by comparing functional and symbolic value.

Abstract: Smart Grids have revolutionized the electricity industry by enabling more efficient control and monitoring of the electricity supply, with a key component being smart meters (SM). These collect information on demand, energy, and harmonic distortion, among others, which must be stored and managed efficiently in a metering data management system (MDMS). The MDMS must ensure that a complete set of data is obtained for use in algorithms to ensure the reliability and quality of the power supply. To address the challenge of management the big data generated by SM, short, medium, and long-term measurement forecasting techniques have been proposed, highlighting the use of artificial intelligence such as Artificial Neural Networks (ANN) and Deep Learning (DL) methods due to their ability to adapt to different input and output variables with various time horizons. In addition, the influence of the diversity of Information and Communication Technologies (ICT) on the update time and data storage in the MDMS is highlighted. In this sense, this work aims to identify which ANN or DL architecture(s) could be more suitable for enterprise, survey, or research applications, demonstrating favorable performance metrics in different scenarios of sampling frequency and typical data update times in Smart Grids. This is relevant due to the need for MDMS to perform multivariate and multi-pass predictions in the short term to complete the information until the information is available or updated.

Resumen: Las Redes Eléctricas Inteligentes de Distribución (REID) han revolucionado la industria eléctrica al permitir un control y monitoreo más eficiente del suministro eléctrico, con un componente clave siendo los medidores inteligentes (SM). Estos recopilan información sobre la demanda, energía, distorsión armónica, entre otros, que deben ser almacenados y gestionados eficientemente en un sistema de gestión de datos de medición (MDMS). El MDMS debe garantizar la obtención de un conjunto completo de datos para su uso en algoritmos que aseguren la confiabilidad y calidad del suministro eléctrico. Para abordar el desafío de gestionar la gran cantidad de datos generados por los SM, se han propuesto diferentes técnicas de predicción de mediciones a corto, mediano y largo plazo, destacando el uso de inteligencia artificial como las Redes Neuronales Artificiales (ANN) y métodos de Aprendizaje Profundo (DL) debido a su capacidad de adaptación a diferentes variables de entrada y salida con diversos horizontes temporales. Además, se destaca la influencia de la diversidad de Tecnologías de la Información y Comunicación (TIC) en el tiempo de actualización y almacenamiento de datos en un MDMS. En este sentido, este trabajo tiene como objetivo identificar qué arquitectura o arquitecturas de ANN o DL podrían ser más adecuadas para aplicaciones en empresas, estudios o investigaciones, demostrando métricas de rendimiento favorables en diferentes escenarios de frecuencia de muestreo y tiempos de actualización de datos típicos en un REID. Esto es relevante debido a la necesidad del MDMS de realizar predicciones multivariables y multipaso a corto plazo para completar la información, hasta que la misma esté disponible o se actualice.

Abstract: The integration of electric mobility is real nowadays. Government policies increasingly focus on encouraging the use of electric vehicles (EVs); particularly, replacing conventional public mobility with electric buses. An adequate energy management of electric bus systems must optimize resource usage, and extend the lifespan of transport units and charging stations, while providing quality service to users. The performance of the EV transport system depends on various deterministic and stochastic variables that need to be accurately simulated to analyze its behavior as closely as possible to real conditions. In this study, a model for the energy analysis of EVs has been implemented, by using the software SUMO (Simulation of Urban Mobility) and applying it to public transport routes in Quito, Ecuador. Through the executed simulations, energy consumption has been estimated and, a sensitivity analysis of the energy consumption of electric bus units to the variations in relevant parameters in the energy management of public transport systems, has been carried out. The impact of certain parameters on energy consumption has been verified, by indicating a significant decrease in the autonomy of EVs on the simulated route under very similar to reality operating conditions. For study case, autonomy reduction of electric bus is around 27% in comparison with manufacturer's specifications. The analysis of energy performance under various traffic scenarios will allow future optimizations of the electric public transport system operation, since traffic levels, variable traffic flow, and pronounced changes in terrain elevation, are considered.

Resumen: La integración de la movilidad eléctrica es una realidad en el mundo actual, las políticas gubernamentales se enfocan cada vez más en incentivar el uso de vehículos eléctricos (VE) particulares, pero, principalmente en reemplazar la movilidad pública convencional por el uso de buses eléctricos. Una adecuada gestión energética de los sistemas de buses eléctricos debe optimizar el uso de recursos, prolongando la vida útil de las unidades de transporte, estaciones de carga y brindando siempre un servicio de calidad a sus usuarios. El desempeño del sistema de transporte mediante VE depende de diversas variables determinísticas y estocásticas que necesitan ser debidamente simuladas a fin de analizar su comportamiento, lo más cercano a las condiciones reales. En el presente trabajo, mediante la aplicación del software SUMO (Simulation of Urban Mobility), se ha implementado un modelo para el análisis energético de VE y se lo ha aplicado en rutas de transporte público en Quito-Ecuador. A partir de las simulaciones realizadas se ha estimado el consumo energético y se ha efectuado un análisis de sensibilidad del consumo energético de las unidades de buses eléctricos ante variaciones de parámetros relevantes en la gestión energética de sistemas de transporte público. Para el caso de estudio se comprueba la reducción de la autonomía del bus eléctrico en 27% de acuerdo con la información del fabricante. El análisis del desempeño energético realizado bajo diversos escenarios de tráfico permitirá en futuros trabajos optimizar la operación de los sistemas de transporte público eléctrico, considerando niveles de tráfico, flujo vehicular variable y pronunciados desniveles en su relieve.

Abstract: The Intensity-Duration-Frequency (IDF) curves are a way to visualize and represent extreme hydrometeorological rainfall events. In this article, an analysis of convective rainfall events recorded at the La Piedra Meteorological Station, Villa Clara, Cuba, was conducted. To develop IDF curves, the 2006-2019 time series was analyzed. A partial duration series was generated, including intervals from 20 minutes to 4320 minutes, subjected to an outlier detection process. The series was divided into two categories: one for durations ≤ 720 minutes and another for durations > 720 minutes. The resulting series underwent non-parametric tests to assess their independence, randomness, homogeneity, and seasonality. Subsequently, they were fitted to the Generalized Pareto probability distribution and to a parametric equation of the Montana model, and then the curves were plotted for return periods of 10, 50 and 100. The Montana model led to obtaining correlation coefficients greater than 0.90 compared to the other methods used, significantly improving the quality of the fit in both categories. This research provides information to understand and plan the management of intense climatic phenomena and adequate risk management in an area where such studies are lacking, facilitating access to crucial data essential in the design and execution of hydraulic engineering projects in the region.

Resumen: Las curvas de Intensidad-Duración-Frecuencia (IDF) son una manera de visualizar y representar los eventos hidrometeorológicos extremos de lluvia. En este artículo se llevó a cabo un análisis de eventos de lluvias convectivas registrados en la Estación Meteorológica La Piedra, Villa Clara, Cuba. Para desarrollar curvas IDF se analizó la serie temporal 2006-2019. Se generó una serie de duración parcial que incluyó intervalos de 20 minutos hasta 4320 minutos, sometiéndola a un proceso de detección de datos anómalos. La serie se dividió en dos categorías: una para duraciones ≤ 720 minutos y otra para duraciones > 720 minutos. Las series resultantes se sometieron a pruebas no paramétricas para evaluar su independencia, aleatoriedad, homogeneidad y estacionalidad. Posteriormente, se procedió a ajustarlas a la distribución probabilística Generalizada de Pareto y a una ecuación paramétrica del modelo de Montana. Luego se grafica la representación de las curvas para períodos de retorno de 10, 50 y 100 años. El modelo de Montana condujo a la obtención de coeficientes de correlación superiores a 0.90 y a los demás métodos utilizados, mejorando significativamente la calidad del ajuste en ambas categorías. Esta investigación aporta información para comprender y planificar la gestión de fenómenos climáticos intensos, así como para una adecuada gestión de riesgos en una zona donde no se cuenta con este tipo de estudios. Asimismo, facilita el acceso a datos cruciales que resultan fundamentales en el diseño y ejecución de proyectos de ingeniería hidráulica en la zona.

Resumen El sector turístico en la actualidad está marcado por las concepciones de gestión, los espacios y la visión económica de las regiones, territorios y ciudades. Además, se aprecia que, como industria y como campo, debe contribuir al desarrollo social y comunitario sostenible en función de elevar la calidad de vida de los habitantes. El objetivo de la investigación estuvo encaminado en analizar la producción científica sobre turismo sostenible en la base de datos SCOPUS en el período 2022-2024. Para ello se implementó un diseño mixto en dos etapas, con un estudio bibliométrico como principal y una revisión hermenéutica de la literatura adaptada a los intereses cognoscitivos y metas de la investigación. Los resultados de la primera etapa evidenciaron un ligero incremento de la producción del año 2022 al año 2023, siendo las áreas más representativas las ciencias sociales y las ciencias ambientales. En la segunda etapa se examinó la relación entre sostenibilidad y turismo en el marco de los objetivos del desarrollo sostenible, así como las principales tendencias y retos.

Abstract The tourism sector today is marked by management concepts, spaces and the economic vision of regions, territories and cities. Furthermore, it is appreciated that, as an industry and as a field, it must contribute to sustainable social and community development in order to raise the quality of life of the inhabitants. The objective of the research was aimed at analyzing the scientific production on sustainable tourism in the SCOPUS database in the period 2022-2024. To achieve this, a mixed design was implemented in two stages, with a bibliometric study as the main one and a hermeneutical review of the literature adapted to the cognitive interests and goals of the research. The results of the first stage showed a slight increase in production from 2022 to 2023,0 with the most representative areas being social sciences and environmental sciences. In the second stage, the relationship between sustainability and tourism was examined within the framework of the sustainable development objectives, as well as the main trends and challenges.

Resumen Los efectos del estrés laboral están asociados con las horas de trabajo y las actividades mentales, como pensar y tomar decisiones, necesarias para la preparación y cualificación de tareas. El objetivo del estudio fue analizar la carga mental percibida en dos instituciones educativas con similitudes socioeconómicas, geográfica y planes educativos similares de la ciudad de Ibagué en el departamento del Tolima, Colombia. Se optó por una metodología cuantitativa no experimental de tipo transversal descriptivo, utilizando el NASA TLX para medir la carga mental, sometiendo los datos a un análisis estadístico no paramétrico de varianzas ANOVA de Kruskal-Wallis y la prueba DSCF para comparaciones post hoc. Los resultados revelaron que las diferencias en la carga de trabajo percibida están más relacionadas con el contexto institucional que con factores individuales como la edad, el género o la asignación académica que imparten los docentes. Esto sugiere que las características internas de las instituciones educativas y las habilidades de afrontamiento utilizadas por los docentes son cruciales para comprender y gestionar adecuadamente la carga mental percibida. Estos hallazgos enmarcan la importancia de adaptar las estrategias de gestión de la carga mental a las particularidades de cada institución educativa para mejorar la calidad de vida laboral de los profesionales y, en última instancia, la calidad de la educación que ofrecen.

Abstract The effects of work stress are associated with work hours and mental activities, such as thinking and decision making, necessary for the preparation and qualification of tasks. The objective of the study was to analyze the perceived mental load in two educational institutions with socioeconomic and geographic similarities and similar educational plans in the city of Ibagué in the department of Tolima, Colombia. A descriptive cross-sectional non-experimental quantitative methodology was chosen, using the NASA TLX to measure mental load, subjecting the data to a non-parametric statistical analysis of variances ANOVA by Kruskal-Wallis and the DSCF test for post hoc comparisons. The results revealed that differences in perceived workload are more related to the institutional context than to individual factors such as age, gender, or the academic assignment taught by teachers. This suggests that the internal characteristics of educational institutions and the coping skills used by teachers are crucial to adequately understand and manage perceived mental load. These findings frame the importance of adapting mental load management strategies to the particularities of each educational institution to improve the quality of work life of professionals and, ultimately, the quality of the education they offer.

Resumen: En los sistemas educativos, los modelos de gestión se adaptan con la finalidad de fortalecer el sistema en su conjunto, mejorar la calidad educativa y propender al desarrollo del conocimiento. Por lo tanto, las instituciones de educación superior (IES) deben adoptar nuevos modelos de gestión que permita una administración eficiente para alcanzar sus metas. El objetivo del presente estudio ha sido analizar tres modelos de gestión: Garvin, Deming e ISO 21001:2018, mediante un enfoque analítico-sintético-deductivo. Además, se ha buscado hacer una triangulación de información que permita realizar un análisis comparativo, considerando que no existe como regla general un modelo de gestión aplicable debido a que cada institución presenta diversas características, procesos estructuración institucional propia. Por esta razón, se ha planteado una propuesta dirigida a establecer nuevas perspectivas en la gestión de instituciones de educación superior en el que se recogen las mejores prácticas y dimensiones adaptadas a los requerimientos a los que se ven abocados las IES. La propuesta se ha basado en cinco categorías del modelo: procesos, funciones, objetivos-metas, mejora continua y liderazgo, en base a la vigencia, pertinencia y adaptabilidad para las IES, considerando aspectos científicos, tecnológicos y demandas de la sociedad.

Abstract Surveillance indicators of the quality of water for human consumption in the Amazon were analysed from 2016 to 2020 using 185,528 samples from 11 microregions. Of the samples analysed, 93.20% were from urban areas, 66.65% were from the public water supply system (WSS), 31.02% were from the Collective Alternative Solution-CAS, and 2.33% from the Individual Alternative Solution-IAS. There was an increase in the number of records by the WSS, with a downwards trend and fluctuations in records for the CAS and the IAS. The quality indicators of chemical and physical parameters for urban areas were higher than those for rural areas and traditional communities. Most of the samples presented pH values below the recommended level. In the quantification of microbiological parameters, a higher presence of total coliforms and E. coli was identified in samples from rural areas and in traditional communities. In conclusion, there were inadequacies in the chemical, physical and microbiological parameters as well as problems related to the supply, storage and surveillance of water distributed for human consumption. These findings indicate the need to build an agenda for public management to address water insecurity and its likely effects on food insecurity in the region. 201 202 185528 185 528 185,52 1 microregions 9320 93 20 93.20 6665 66 65 66.65 WSS , (WSS) 3102 31 02 31.02 SolutionCAS, SolutionCAS Solution CAS, Solution-CAS 233 2 33 2.33 SolutionIAS.

Abstract This study aimed to analyze the role of nurses in hospital management in the face of COVID-19. The study had a qualitative, descriptive, and exploratory approach. The setting was a hospital that was completely transformed to care for patients with COVID-19. At the time of data collection, ten nurses managed the services, and all participated in the semi-structured interview. After thematic analysis, the data were presented in three categories, representing the elements of Donabedian’s triad: structure, process, and result. Category 1 highlighted the hospital structure reconfiguration based on material and people management; category 2 addressed the work process restructuring to achieve goals with safety and quality; and category 3 focused on nurses’ experiences in describing the results achieved and expected. The analysis highlighted the importance of teamwork, involvement, and adaptation of managers in the face of the challenges of a new and life-threatening disease, scarce resources, and the complexity of human relationships in the crisis. In transformational leadership, these nurses encouraged behavior change, professional growth, and resilience. COVID19.

Resumo Objetivou-se analisar a atuação dos enfermeiros na gestão hospitalar frente à COVID-19. O estudo teve uma abordagem qualitativa, do tipo descritivo e exploratório. O cenário foi um hospital que se transformou totalmente para atendimento de pacientes com COVID-19. No momento da coleta de dados, dez enfermeiros estavam à frente da gestão dos serviços, e todos participaram da entrevista semiestruturada. Os dados, após análise temática, foram apresentados em três categorias representativas dos elementos da tríade de Donabedian, ou seja, estrutura, processo e resultado. A categoria 1 realçou a reconfiguração da estrutura hospitalar a partir da gestão de materiais e das pessoas; a categoria 2 abordou a reestruturação do processo de trabalho para alcance das metas com segurança e qualidade; e a categoria 3 focou nas experiências dos enfermeiros na descrição dos resultados alcançados e esperados. A análise evidenciou a importância do trabalho em equipe, do envolvimento e da adaptação do gestor diante dos desafios da doença nova e ameaçadora da vida, dos recursos escassos e da complexidade das relações humanas na crise. Na liderança transformacional esses enfermeiros incentivaram a mudança de comportamento, o crescimento profissional, e resiliência. Objetivouse Objetivou COVID19.
