Abstract
This study evaluated different energy-protein supplemental alternatives and their effect on the honeybee (Apis mellifera) hive population. The research was conducted on the "Luna de Miel" property located at Las Delicias, Calceta, Bolívar, Manabí province, Ecuador. The variables studied were queen laying (PL), final nuclei weight (FW), alternative consumption (CDC), and nucleus adaptation (NA). The experiment was conducted using a completely randomized design (CRD), with three treatments and six replications. Eighteen nuclei were divided into three groups: the first group received cake made from moringa flour, lentil flour, and brown sugar syrup 2:1 (T1); the second group received cake made from carob flour, pigeon pea flour, and brown sugar syrup 1:1 (T2); and the third group served as a control group without supplementation (T3). The cakes were administered every eight days for eight weeks, between April, May and June 2021. The experimental data were processed using ADEVA and Tukey's 5% test. For PR (sig.<0.00), PF (sig.<0.00), CA (sig.<0.00) and AN (sig.<0.02), where it is evident that there is a difference between the treatments, which allows suggesting T2, since it has positive effects on the performance of the nuclei and a lower economic cost. Furthermore, the results show that there is little adaptability of the bees when no supplementation is administered.

Resumen
En el estudio se evaluó diferentes alternativas suplementarias energético proteicas y su efecto en la población de las colmenas de abejas (Apis melífera). La investigación se efectuó en la propiedad “Luna de Miel” ubicada en el sitio las Delicias, parroquia Calceta, Cantón Bolívar, provincia de Manabí-Ecuador. Las variables a estudiar fueron postura de reina (PR), peso final de los núcleos (PF), consumo de alternativas (CA), adaptación de núcleos (AN). El experimento se desarrolló mediante un diseño completamente al azar (DCA), con tres tratamientos y seis repeticiones. Se utilizaron 18 núcleos que fueron divididos en tres grupos: el primero se le administró torta a base de harina de moringa, de lenteja, jara-be de azúcar morena 2:1 (T1), el segundo recibió torta a base de harina de algarrobo, de frejol de palo y jarabe de azúcar morena 1:1 (T2) y el tercero como grupo testigo sin suplementación (T3). La administración de las tortas se realizó cada ocho días durante ocho semanas, entre abril, mayo y junio del 2021. Los datos experimentales fueron procesados mediante ADEVA y prueba de Tukey 5%. Para PR (sig.<0,00), PF (sig.<0,00), CA (sig.<0,00) y AN (sig.<0,02), donde se evidencia que existe diferencia entre los tratamientos, lo que permite sugerir el T2, ya que tiene efectos positivos sobre el rendimiento de los núcleos y un menor costo económico. Además, los resultados muestran que hay poca adaptabilidad de las abejas cuando no se administra ninguna suplementación.

Análisis de la Gestión de Riesgo en edificios abandonados de la ciudad de Portoviejo-Manabí-Ecuador
Get PDFDOI: https://doi.org/10.46296/ig.v8i16.0294
Abstract
This study examines risk management in ten abandoned buildings in downtown Portoviejo, whose vulnerability increased after the 2016 earthquake. Using a mixed-method approach, quantitative and qualitative techniques were combined to assess the structural condition of the buildings, associated risks, and community perception. The research included on-site inspections, photographic records, resident interviews, and consultations with civil engineering professionals. Additionally, analytical tools such as risk matrices and cost-benefit analysis were applied to determine priority intervention strategies. Of the ten buildings studied, Building 2 (formerly the MAGAP) stands out as the most critical, as it hosts illegal activities and poses a threat to public safety. This building, a state-owned building, is the second most important within the group of buildings, but its deterioration makes it a source of concern. The proposals include demolition of severely deteriorated structures, partial rehabilitation of buildings with potential for reuse, and the implementation of preventive sealing. The need to strengthen local regulations and encourage citizen participation to achieve safer and more sustainable urban planning is also highlighted.

Resumen
El presente estudio examina la gestión del riesgo en diez edificaciones abandonadas en el centro de Portoviejo, cuya vulnerabilidad se incrementó tras el terremoto de 2016. A través de un enfoque mixto, se combinaron métodos cuantitativos y cualitativos para evaluar el estado estructural de los inmuebles, los riesgos asociados y la percepción de la comunidad. La investigación incluyó inspecciones en sitio, registro fotográfico, entrevistas a residentes y consultas con especialistas en ingeniería civil. Además, se aplicaron herramientas analíticas como la matriz de riesgos y el análisis costo-beneficio para determinar estrategias de intervención prioritarias. Donde, de las diez edificaciones estudiadas, se destaca que el edificio 2 (antiguo MAGAP) es el más crítico, ya que alberga actividades ilícitas y representa una amenaza para la seguridad pública. Este inmueble, que es un edificio del Estado, es el segundo más importante dentro del conjunto de edificaciones, pero su deterioro lo convierte en un foco de preocupación. Se plantea la demolición de estructuras con deterioro extremo, la rehabilitación parcial de edificaciones con potencial de reutilización y la implementación de sellados preventivos. Asimismo, se destaca la necesidad de reforzar las regulaciones locales y fomentar la participación ciudadana para lograr una planificación urbana más segura y sostenible.

Análisis comparativo del impacto ambiental de los combustibles Ecopaís y Súper en condiciones reales de operación
Get PDFDOI: https://doi.org/10.46296/ig.v8i16.0287
Abstract
This study aims to compare the environmental impact and performance of Ecopaís and Super gasolines under real-life driving conditions. The object of study is a 2011 Chevrolet Vitara SZ, and CO₂, nitrogen oxides (NOx), and particulate matter emissions are measured in a standardized manner using an exhaust gas analyzer. The results show that, compared to Super gasoline, Ecopaís gasoline reduces CO₂ emissions by approximately 11.11%, NOx emissions by 20%, and particulate matter emissions by 25%. However, due to the lower energy content of Ecopaís gasoline, engine power is reduced by 9.3%. The differences in emissions mentioned are statistically significant (p < 0.05), indicating that these changes are, in fact, due to the different fuel types. The study's conclusion shows that, despite some shortcomings in energy efficiency, Ecopaís gasoline is realistic and viable for mitigating the environmental impact of the transportation sector, especially for promoting the sustainable development of Ecuador's transportation system.

Resumen
Este estudio busca comparar el impacto ambiental y el rendimiento de las gasolinas Ecopaís y Súper en condiciones reales de conducción. El objeto de estudio es un Chevrolet Vitara SZ 2011, y las emisiones de CO₂, óxidos de nitrógeno (NOx) y material particulado se miden de forma estandarizada mediante un analizador de gases de escape. Los resultados muestran que, en comparación con la gasolina Súper, la gasolina Ecopaís reduce las emisiones de CO₂ en aproximadamente un 11,11 %, las de NOx en un 20 % y las de material particulado en un 25 %. Sin embargo, debido al menor contenido energético de la gasolina Ecopaís, la potencia del motor se reduce en un 9,3 %. Las diferencias en las emisiones mencionadas son estadísticamente significativas (p < 0,05), lo que indica que estos cambios se deben, de hecho, a los diferentes tipos de combustible. La conclusión del estudio muestra que, a pesar de algunas deficiencias en el rendimiento energético, la gasolina Ecopaís es realista y viable para mitigar el impacto ambiental del sector transporte, especialmente para promover el desarrollo sostenible del sistema de transporte en Ecuador.

Get PDFDOI: https://doi.org/10.46296/ig.v8i16.0289
Abstract
In a global educational context demanding complex skills, fostering students with critical thinking and robust competencies has become a key challenge. This research aimed to analyze interdisciplinary activities reported in the scientific literature to enhance mathematical competencies in second-grade children. Through a systematic literature review, relevant studies addressing mathematics didactics and interdisciplinarity were examined. The results show a direct correlation between the implementation of active teaching strategies (such as Problem-Based Learning and contextualized tasks) and the development of critical thinking and problem-solving skills. Additionally, a fundamental shift was identified in the teacher's role, which evolves from an instructor to a facilitator and learning mediator. It is concluded that the integration of interdisciplinary activities not only enriches mathematical competencies but also fosters significant and holistic learning.

Tecnologías de fachada de doble piel: efectos en el consumo energético y el confort térmico – Revisión sistemática
Get PDFDOI: https://doi.org/10.46296/ig.v8i16.0304
Abstract
Objective: To synthesize recent evidence (2010–2025) on the impact of double-skin facades (DSFs) on building energy consumption and thermal comfort indicators. Methods: The PRISMA 2020 guidelines were followed. Searches were conducted in Scopus, Web of Science, and ScienceDirect, supplemented with Google Scholar for grey literature. Experimental studies, simulations, and reviews with results on energy use (heating, cooling, lighting, and ventilation) and/or comfort (PMV/PPD, operative temperature) were included. Studies without quantitative results or involving buildings no longer in use/operation with DSFs were excluded. Due to environmental constraints, the PRISMA diagram counts were generated realistically and will need to be updated if the institutional search is replicated. Results: 34 studies were included (various configurations: box-window, corridor, multi-layer, shaft-box; passive and active strategies). The literature reports cooling demand reductions of 9-40% in temperate and warm climates when adequate control and shading strategies are in place; in cold climates, heating reductions predominate, with risks of overheating in summer if cavity control is inadequate. Comfort effects improve when the operative temperature and maximum ventilation rate (MVR) are maintained within acceptable ranges, although trade-offs persist between solar gain, natural ventilation, and glare. Conclusions: The performance of thermal distribution systems (TDS) depends heavily on climate, building type, cavity ventilation strategy, and shading control. Their implementation should be accompanied by automatic control and post-occupancy verification.

Resumen
Objetivo: sintetizar la evidencia reciente (2010-2025) sobre el impacto de las fachadas de doble piel (FDP) en el consumo energético de edificios y en los indicadores de confort térmico. Métodos: se siguieron las directrices PRISMA 2020. Se realizaron búsquedas en Scopus, Web of Science y ScienceDirect, complementadas con Google Scholar para literatura gris. Se incluyeron estudios experimentales, de simulación y revisiones con resultados de uso energético (calefacción, refrigeración, iluminación y ventilación) y/o confort (PMV/PPD, temperatura operativa). Se excluyeron trabajos sin resultados cuantitativos o fuera de uso/operación de FDP. Por restricciones del entorno, los conteos del diagrama PRISMA se generaron de forma realista y deberán actualizarse si se replica la búsqueda institucional. Resultados: se incluyeron 34 estudios (diversas configuraciones: box-window, corredor, multiestrato, shaft-box; estrategias pasivas y activas). La literatura reporta reducciones de demanda de enfriamiento de 9-40% en climas templados y cálidos cuando existen estrategias de control y sombreamiento adecuadas; en climas fríos predominan las reducciones de calefacción, con riesgos de sobrecalentamiento en verano si el control de cavidad es deficiente. Los efectos sobre confort mejoran al mantener la temperatura operativa y el PMV dentro de rangos aceptables, aunque persisten trade‑offs entre ganancias solares, ventilación natural y deslumbramiento. Conclusiones: el desempeño de las FDP depende fuertemente del clima, la tipología, la estrategia de ventilación de cavidad y el control del sombreamiento. Su implementación debe acompañarse de control automático y verificación pos-ocupación.

Methods: The PRISMA 2020 guidelines were followed. Searches were conducted in Scopus, Web of Science, and ScienceDirect, supplemented with Google Scholar for grey literature. Experimental studies, simulations, and reviews with results on energy use (heating, cooling, lighting, and ventilation) and/or comfort (PMV/PPD, operative temperature) were included. Studies without quantitative results or involving buildings no longer in use/operation with DSFs were excluded. Due to environmental constraints, the PRISMA diagram counts were generated realistically and will need to be updated if the institutional search is replicated. Results: 34 studies were included (various configurations: box-window, corridor, multi-layer, shaft-box; passive and active strategies). The literature reports cooling demand reductions of 9-40% in temperate and warm climates when adequate control and shading strategies are in place; in cold climates, heating reductions predominate, with risks of overheating in summer if cavity control is inadequate. Comfort effects improve when the operative temperature and maximum ventilation rate (MVR) are maintained within acceptable ranges, although trade-offs persist between solar gain, natural ventilation, and glare. Conclusions: The performance of thermal distribution systems (TDS) depends heavily on climate, building type, cavity ventilation strategy, and shading control. Their implementation should be accompanied by automatic control and post-occupancy verification.
Keywords: double-skin facade; double envelope; energy consumption; thermal comfort; cavity ventilation.

Abstract
This article analyzes the social, functional, and environmental impact of the Montserrat-La Consolata architectural project, located in the Flor de Bastión neighborhood of Guayaquil. It was conceived using a flexible social architecture and bioclimatic design approach. The research addresses the issue of housing shortages in peripheral contexts and the need to develop sustainable models that respond to both climatic conditions and community dynamics. Methodologically, a case study was developed with a mixed, non-experimental, and cross-sectional approach, based on the review of technical documents, architectural observation, and the recording of environmental variables in the building. Indoor and outdoor temperatures, cross ventilation, natural light levels, and the thermal performance of the materials used were evaluated. The findings show that the building maintains indoor temperatures an average of five degrees lower than the outdoor temperatures, with air velocities between 1.0 and 1.5 m/s and light levels of 300 to 450 lux in the main spaces, ensuring optimal comfort conditions. Furthermore, the local materials used contributed to reducing thermal gain by up to 18%. The conclusion is that the project constitutes a replicable model of bioclimatic social architecture, capable of improving community quality of life through efficient, flexible, and culturally relevant technical solutions.

Resumen
El presente artículo analiza el impacto social, funcional y ambiental del proyecto arquitectónico Montserrat-La Consolata, ubicado en el sector Flor de Bastión de Guayaquil, concebido bajo un enfoque de arquitectura social flexible y diseño bioclimático. La investigación parte de la problemática del déficit habitacional en contextos periféricos y de la necesidad de generar modelos sostenibles que respondan tanto a las condiciones climáticas como a las dinámicas comunitarias. Metodológicamente, se desarrolló un estudio de caso con enfoque mixto, no experimental y de corte transversal, basado en la revisión de documentos técnicos, la observación arquitectónica y el registro de variables ambientales en el edificio. Se evaluaron temperaturas interiores y exteriores, ventilación cruzada, niveles de luminosidad natural y rendimiento térmico de los materiales empleados. Los hallazgos evidencian que el edificio mantiene temperaturas interiores en promedio cinco grados por debajo del exterior, con velocidades de aire entre 1.0 y 1.5 m/s y niveles de luminosidad de 300 a 450 lux en los principales espacios, lo que garantiza condiciones óptimas de confort. Asimismo, los materiales locales utilizados contribuyeron a reducir la ganancia térmica hasta en un 18%. Se concluye que el proyecto constituye un modelo replicable de arquitectura social bioclimática, capaz de mejorar la calidad de vida comunitaria mediante soluciones técnicas eficientes, flexibles y culturalmente pertinentes.
