Resumen: La investigación determinó el efecto de la mediación de un videojuego educativo en el fortalecimiento de la resolución de problemas de matemáticas. El método cuantitativo con alcance descriptivo fue aplicado. La muestra fue no probabilística con 20 estudiantes de la Institución Educativa San Jorge, en la vereda Las Damas, Municipio de Purificación, Departamento de Tolima. Las variables estudiadas fueron: desempeño en resolución de problemas, mecánicas y percepción del videojuego. La encuesta inicial reflejó que un 90% no poseían habilidades matemáticas básicas y tenían una percepción negativa del área. Entonces, fue diseñada una estrategia educativa con un videojuego denominado Corredor Matemático de Pensamiento Variacional (Comapeva), en tercera persona con Unity 3D, Adobe Ilustrator y Autodesk 3d. Fue protagonizado por Comaco: joven aventurero que superó retos matemáticos. El guion narrativo combinó elementos del constructivismo, Aprendizaje Basado en Retos (ABR) y modelo instruccional ADDIE (Análisis, Diseño, Desarrollo, Implementación y Evaluación). La herramienta fue implementada con el apoyo de los docentes. Con el videojuego el 100% de los estudiantes resolvieron retos con diversas estrategias. Disminuyó un 21% el tiempo de desarrollo de los problemas, y un 33% las solicitudes de apoyo del docente. La concentración, atención, memoria, agilidad mental, interpretación y análisis fueron fortalecidas. El videojuego facilitó la construcción de conocimientos en matemáticas de forma sustancial. En consecuencia, fue innovador, motivador y permitió la trasformación de prácticas educativas según las necesidades de aprendizaje.

Abstract: The research considers the effect of the mediation of an educational video game in strengthening mathematics problem solving. The quantitative method with a descriptive scope was applied. The sample was non-probabilistic with 20 students from the San Jorge Educational Institution, in Las Damas village, Municipality of Purificación, Department of Tolima. The variables studied were problem-solving performance, game mechanics, and videogame perception. The initial survey showed that 90% of the students did not have basic mathematical skills and had a negative perception of the subject area. Therefore, an educational strategy was then designed using a video game called the Variational Thinking Mathematical Corridor (Comapeva). The game was developed in third person using Unity 3D, Adobe Illustrator, and Autodesk 3d. It starred Comaco: a young adventurer who overcame mathematical challenges. The narrative script combined elements of constructivism, Challenge-Based Learning (CBL) and instructional model ADDIE (Analysis, Design, Development, Implementation and Evaluation). The tool was implemented with the support of the teachers. With the video game, 100% of the students were able to solve challenges using various strategies. Problem development time decreased by 21%, and teacher support requests decreased by 33%. Concentration, attention, memory, mental agility, interpretation, and analysis skills were all strengthened. The video game facilitated the construction of knowledge in mathematics in a substantial way. Consequently, the video game was found to be innovative and motivating, and it allowed for the transformation of educational practices according to the students' learning needs.

Abstract Over the last decade, the Mexican federal government has published several planning instruments promoting land-use planning and regional development. Various administrative agencies participate in developing these instruments, which suggest a fragmented and disarticulated management. This article examines whether the National Strategy for National Strategy for Spatial Planning (ENOT) 2020-2040, the current operating instrument, restores the steering role in territorial governance to the national State. After a review of the normative tools contained in the Official Journal of the Federation, the findings suggest that the ENOT favours governance based on essential projects. The Mayan Train, the Development Programme for the Isthmus of Tehuantepec, and the Free Zone Programme for the Northern and Southern Borders suggest that another model of territorial governance has emerged in Mexico.

Resumen El Gobierno federal mexicano ha publicado durante la última década distintos instrumentos de planificación para promover el ordenamiento del territorio y desarrollo regional. Su elaboración, a cargo de varias instancias administrativas, revelaría una gestión fragmentada y desarticulada. Este artículo indaga si la Estrategia Nacional de Ordenamiento Territorial (ENOT) 2020-2040, instrumento vigente en esta materia, logra restituirle al Estado mexicano la rectoría en la gobernanza territorial. Luego de una revisión de las herramientas normativas que constan en el Diario Oficial de la Federación, los hallazgos sugieren que la ENOT privilegia una gobernanza basada en proyectos prioritarios. El Tren Maya, el Programa de Desarrollo para el Istmo de Tehuantepec y el Programa Zona Libre de las Fronteras Norte y Sur son indicios de que otro modelo de gobernanza territorial ha surgido en México.

ABSTRACT Integrated production systems have emerged as a sustainable production strategy in intensifying land use with minimal impact on ecosystem functions. This study used precision agriculture tools to investigate the spatial variability of soil and vegetation properties in an integrated crop-livestock-forestry (ICLF) and in an integrated livestock-forestry (ILF) area of São Carlos city, SP, Brazil. Consequently, the following were assessed: (1) the soil physicochemical properties, (2) the electrical resistivity, and (3) the attributes of the Eucalyptus urograndis crop comprising the study area. Samplings were performed in (1) August 2021 at depths of 0-0.2 and 0.2-0.4 m; (2) October 2021 at depths of 0-0.5, 0-1.0, and 0-2.0 m; and (3) April 2021 and April 2022. Results indicated that the values for soil fertility parameters were suitable for crop development and presented low spatial variability. Soil analyses indicated low acidity, high levels of organic matter, average cation exchange capacity, phosphorus and potassium contents, high base saturation, and calcium and magnesium levels. However, locations with greater spatial variability for calcium were observed, reflecting cation exchange capacity and base saturation variability. Soil granulometry and electrical resistivity had a low spatial variability at the surface layer. Even without differences in the soil properties, there was a difference of 15% in the larger wood volume in the ILF then ICLF system. functions croplivestockforestry livestock forestry (ICLF livestockforestry (ILF city SP Brazil Consequently assessed 1 (1 2 (2 3 (3 202 00.2 002 0 0.2 0-0. 0.20.4 0204 0.4 4 0.2-0. m 00.5, 005 0.5, 5 0-0.5 01.0, 010 1.0, 0-1.0 02.0 020 2.0 0-2. 2022 acidity matter contents However observed layer 15 system ( 20 00 00. 02 0. 0-0 0.20. 04 0.2-0 00.5 05 0.5 01 01.0 10 1.0 0-1. 02. 2. 0-2 0- 0.20 0.2- 01. 1. 0-1

ABSTRACT As a result of the COVID 19 pandemic, a set of modifications were implemented in the way it was taught. Higher education institutions in Chile were not immune to this phenomenon, and to this scenario was added a set of trends that had already been raising the need to review didactics, in terms of what and how it is taught. Different initiatives led to the development and implementation of didactic strategies that sought to solve the challenges faced by the educational system. Even though innumerable articles referring to the implementation of these didactic innovations have appeared, the evidence regarding the impact of their adaptations remains scarce. The objective of this research is to evaluate the impact of the use of the Case Method on the academic performance of the students of the calculus subject of the Business Administration Engineering degree at a Chilean higher education institution in an online context. through a difference-in-differences model using control groups generated with the Propensity Score Matching technique. The results show a positive and statistically significant effect on student grades.

RESUMEN Producto de la pandemia de COVID 19 se implementaron un conjunto de modificaciones en la forma cómo se enseñaba. Las instituciones de educación superior en Chile no estuvieron ajenas a ese fenómeno, y a este escenario se sumó un conjunto de tendencias que ya venían planteando la necesidad de revisar la didáctica, en cuánto al qué y al cómo se enseña. Diferentes iniciativas llevaron al desarrollo e implementación de estrategias didácticas que buscaron resolver los desafíos que enfrentaba el sistema educativo. Aun cuando han surgido innumerables artículos referidos a la implementación de estas innovaciones didácticas, la evidencia respecto del impacto de sus adaptaciones permanece escasa. El objetivo de la presente investigación es evaluar el impacto del uso del Método del Caso en el rendimiento académico de los estudiantes de los estudiantes de la asignatura de cálculo de la carrera Ingeniería en Administración de Empresas de una institución de educación superior chilena en un contexto online mediante un modelo de diferencias en diferencias usando grupos de control generados con la técnica de Propensity Score Matching. Los resultados muestran un efecto positivo y estadísticamente significativo en las calificaciones de los estudiantes.

Resumen La moderna Sociedad del Conocimiento percibe una innovadora característica basada en manejar los contenidos curriculares, potenciando el pensamiento lógico matemático por medio de plataformas y aplicaciones digitales. El objetivo del presente trabajo se centraliza en analizar estrategias didácticas aplicadas por docentes para potenciar las habilidades matemáticas en los estudiantes del nivel de Bachillerato General Unificado dentro de la Unidad Educativa “Eidan Abel Erique Cercado” del cantón San Vicente. El aspecto metodológico se basó en el enfoque mixto, empleando como instrumento primordial una prueba pedagógica que mide las destrezas del pensamiento numérico, así como los indicios de una entrevista semi estructurada y los aportes de docentes del área de matemáticas como participantes dentro de un grupo focal. Se comprobó la predisposición para un trabajo orientado bajo la plataforma Khan Academy, necesaria para beneficiar las habilidades del pensamiento numérico poco perfeccionadas en el estudiante. Finalmente, se denotaron aquellas estrategias empleadas por los docentes las cuales no afirman una estimulación consistente para potenciar las habilidades numéricas, demostradas bajo un nivel poco aceptable en el afianzamiento de la resolución de problemas con enfoque matemático en los estudiantes.

Abstract The modern knowledge society perceives an innovative characteristic based on managing curricular contents, promoting mathematical logical thinking through digital platforms and applications, the purpose of this work is focused on determining the existing perception with the use of the Khan Academy platform in the mathematical skills and how teachers focus didactic strategies to enhance mathematical skills in students of the Unified General Baccalaureate level within the "Eidan Abel Erique Cercado" Educational Unit of the San Vicente canton. The methodological aspect was based on the paradigm of the mixed approach, using as a primary instrument a pedagogical test that measures the skills of numerical thinking, as well as the indications of a semi-structured interview and the contributions of teachers in the area of mathematics as participants within a focus group. The predisposition for a work oriented under the Khan Academy platform, necessary to benefit the slightly improved numerical thinking skills in the student, was verified. Finally, those strategies used by teachers were denoted which do not affirm a perennial stimulation to enhance numerical skills, demonstrated under an unacceptable level in the consolidation of problem solving with a mathematical approach in students.

ABSTRACT Erectile dysfunction is observed in about 50% of men. It has been found that diabetes mellitus increases its prevalence to 19-86.3%, necessitating attention to a therapeutic strategy. Among the available treatment methods, intracavernosal injections of mesenchymal stem cells have proven to be particularly effective. Objective The purpose of study is to assess and analyse the effectiveness of their use in the treatment of erectile dysfunction in patients with diabetes mellitus. Materials and Methods The literature search was conducted using systematic methods and analysis in databases such as Web of Science, Scopus, PubMed, Elsevier, and Springer, with 41 sources included for further review. Results The study highlights microangiopathic and neuropathic links as key factors in erectile dysfunction development in diabetic patients, stemming from endothelial dysfunction and conductivity disturbances. Mesenchymal stem cell therapy from bone marrow, adipose tissue, and umbilical cord mitigates pathogenic impact through regenerative and anti-apoptotic effects. Due to this, most studies indicate high efficacy of the treatment and rapid therapeutic action through intracavernosal administration. Some studies suggest an increase in the body’s receptor sensitivity to other drugs, such as sildenafil. Conclusion From the perspective of further research on this issue, standardising the preparation of stem cells and the treatment method using a large sample size is essential to introduce such a method as an extremely promising therapy for this delicate issue in men into practical medicine. The practical value of the study lies in the systematisation of information on different sources of mesenchymal stem cells for treating erectile dysfunction. 50 1986.3%, 19863 19 86.3%, 86 3 19-86.3% strategy effective Science Scopus PubMed Elsevier Springer 4 review disturbances marrow tissue antiapoptotic anti apoptotic effects administration bodys body s drugs sildenafil medicine 5 1986 1986.3% 1 863 86.3% 8 19-86.3 198 1986.3 86.3 19-86. 1986. 86. 19-86 19-8 19-

Abstract Background The treatment for atopic dermatitis (AD) has been the focus of clinical research, and behavioral intervention is considered an indispensable treatment method. To our knowledge, no relevant meta-analysis has evaluated the effects of behavioral interventions on atopic dermatitis. Objectives To evaluate the effects of behavioral interventions on atopic dermatitis. Methods The authors searched PubMed, EMBASE, and Cochrane CENTRAL to retrieve relevant RCTs (up to Feb 2022). The search strategy involved a combination of related keywords. The Cochrane Q and I2 statistics were used to assess heterogeneity. Results Six RCTs involving seven reports with 246 patients were included. The results suggested that behavioral interventions could relieve eczema severity (correlation coefficient [r = −0.39]; p < 0.001) and scratching severity significantly (r = −0.19; p = 0.017), while not affect itching intensity (r = −0.02; p = 0.840). A sensitivity analysis confirmed the robustness of the results. Study limitations An important limitation of this study was the insufficient number of RCTs and the limited sample size. In addition, the study lacked a control group receiving a type of intervention other than the experimental protocol. Another limitation was the short duration of follow-up. Conclusions This study suggests that behavioral interventions could be effective in treating atopic dermatitis by reducing eczema and scratching severity. Additionally, habit-reversal behavioral therapy may be more effective for treating atopic dermatitis.

Abstract Background Molecularly targeted therapies, such as monoclonal antibodies (mAbs) and Janus Kinase inhibitors (JAKis), have emerged as essential tools in the treatment of dermatological diseases. These therapies modulate the immune system through specific signaling pathways, providing effective alternatives to traditional systemic immunosuppressive agents. This review aims to provide an updated summary of targeted immune therapies for inflammatory skin diseases, considering their pathophysiology, efficacy, dosage, and safety profiles. Methods The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A systematic search was conducted on PubMed over the past 10 years, focusing on randomized clinical trials, case reports, and case series related to targeted immune therapies in dermatology. Eligibility criteria were applied, and data were extracted from each study, including citation data, study design, and results. Results We identified 1360 non-duplicate articles with the initial search strategy. Title and abstract review excluded 1150, while a full-text review excluded an additional 50 articles. The review included 143 studies published between 2012 and 2022, highlighting 39 drugs currently under investigation or in use for managing inflammatory skin diseases. Study limitations The heterogeneity of summarized information limits this review. Some recommendations originated from data from clinical trials, while others relied on retrospective analyses and small case series. Recommendations will likely be updated as new results emerge. Conclusion Targeted therapies have revolutionized the treatment of chronic skin diseases, offering new options for patients unresponsive to standard treatments. Paradoxical reactions are rarely observed. Further studies are needed to fully understand the mechanisms and nature of these therapies. Overall, targeted immune therapies in dermatology represent a promising development, significantly improving the quality of life for patients with chronic inflammatory skin diseases. mAbs (mAbs JAKis, JAKis , (JAKis) diseases pathways agents pathophysiology efficacy dosage profiles Metaanalyses Meta PRISMA (PRISMA guidelines 1 years trials reports applied design 136 nonduplicate non duplicate strategy 1150 fulltext full text 5 14 201 2022 3 emerge treatments observed Overall development (JAKis 13 115 20 202 11 2

• The extraction of the juice from the filters in the sugar industry enables the production of torula yeast cream to promote swine feeding, allowing the amount of leftover bagasse to be increased to be used to obtain xylitol for the food industry, and to take advantage of the resulting lignocellulosic material as a source of compacted energy for the generation of electricity, in the context of a biorefinery. Assess the alternatives for the production of torula yeast, xylitol and pellets from the extraction of the juice from the filters, considering the context of a biorefinery, for the benefit of swine feeding, the food industry and electricity generation.

Migration, a prevalent global phenomenon, significantly impacts health, particularly in low- to middle-income countries. This article presents a rapid review aimed at mapping projects, lessons and policies concerning sexual and reproductive health (SRH), HIV and migration in southern Africa. Utilising a population-concept-context framework, the review focuses on understanding the scope, nature and extent of interventions, identifying lessons learnt, and assessing existing policies and strategies. A comprehensive search strategy and screening process resulted in 19 studies and reports for inclusion. The review highlighted diverse projects across southern Africa, addressing SRH and HIV among migrants, refugees and asylum seekers. Projects ranged from peer-education interventions to community-based referral systems, aiming to improve knowledge, access and outcomes related to SRH and HIV. The lessons learnt emphasised the importance of community involvement, healthcare worker (HCW) training and inclusive policies to address migrants' diverse needs effectively. Additionally, projects facilitated cross-border collaborations and policy integration, enhancing access to SRH-HIV services and migrant health rights. Despite these efforts, challenges persist, including gender-based violence, financial barriers and xenophobic attitudes among HCWs. Limited access to comprehensive sexuality education and social protection for migrants underscores the need for further policy development and implementation. Nevertheless, existing policies, such as Botswana's inclusive HIV treatment policy and South Africa's National Strategic Plan for HIV, TB and STIs, demonstrate steps towards ensuring migrants' rights to healthcare.

ABSTRACT Limited information exists regarding the impact of planting density on soil fertility, plant productivity, and the phenolic content of calafate (Berberis microphylla G. Forst.) fruits. This study aimed to assess the effects of planting density on the soil, plants, and fruits in a calafate orchard. Four treatments were employed: High-density (HD; 6667 plants ha-1), traditional density (TD; 3333 plants ha-1), medium density (MD; 2222 plants ha-1), and low density (LD; 1667 plants ha-1). In the soil, TD exhibited a 28% increase in basal respiration compared with MD, and a 29% increase in urease compared with HD. Additionally, TD enhanced soil N availability by 57%, ammonium availability by 58%, and Mn availability by 33% compared to LD. Photosystem II experienced an increase with MD and LD (p > 0.05), surpassing TD and HD by 3%. The LD significantly outperformed the other treatments in terms of yield per plant, reaching up to 873 g. Conversely, despite its lower yield per plant, HD produced larger and heavier fruits, albeit at the expense of phenolic content. However, HD and MD, averaging 2.1 t ha-1, generated more fruit per unit area than LD and TD did. Notably, planting density did not affect the fruit antioxidant capacity. These findings suggest that TD planting density in calafate preserves the biological and chemical functions of the soil, while maintaining the antioxidant capacity of calafate fruit.

Abstract Background: Although drought and defoliation increase the risk of death of the seedlings in tropical dry forests, few studies have evaluated the impact of this combined factors on the response of species. Questions: What is the seedling water management strategy and how does it affect their growth? How does the combination of drought and defoliation impact the growth of the species? Studied species: Guazuma ulmifoliaLam andPithecellobium dulce(Roxb.) Benth. Study sites and dates: The study was carried out in Autlán, Jalisco, México, between October 2021 and February 2022. Methods: In a greenhouse, the seedlings were submitted to four combined water availability and defoliation treatments. The stomatal conductance and leaf water potential were recorded, and the relative growth rate, final biomass, and biomass allocation were calculated. Results: G. ulmifoliashowed to be an anisohydric species, registered higher growth, and was the most affected by drought, whileP. dulcewas more isohydric, registered lower growth and defoliation was the main stressor. The synergy between Drought × Defoliation negatively impacted the two species' relative growth rate. Conclusions: Regardless of the water management strategy, in the early phases of development, the impact of drought and defoliation was magnified when stressors interacted. Therefore, Drought × Defoliation can limit the regeneration of species within forests, promoting the loss of biodiversity and detriment to the functioning of ecosystems.

Resumen Antecedentes: Aunque la sequía y la defoliación incrementan el riesgo de muerte de las plántulas en los bosques tropicales secos, pocos estudios han evaluado la respuesta de las especies forestales con la combinación de estos factores. Preguntas: ¿Cuál es la estrategia de uso del agua de las plántulas y cómo afecta su crecimiento? ¿Cuál es el impacto de la combinación de Sequía × Defoliación sobre el crecimiento de las especies? Especies estudiadas: Guazuma ulmifolia Lam y Pithecellobium dulce (Roxb.) Benth. Sitio y año de estudio: Autlán, Jalisco, México, entre octubre del 2021 y febrero del 2022. Métodos: En invernadero, las plántulas se sometieron a cuatro tratamientos combinados de disponibilidad de agua y defoliación. Se registró la conductancia estomática y el potencial hídrico de la hoja, y se calculó la tasa de crecimiento relativa, biomasa final y asignación de biomasa. Resultados: G. ulmifolia mostró ser anisohídrica, registró mayor crecimiento y fue más afectada por la sequía, mientras que P. dulce fue más isohídrica, registró menor crecimiento y la defoliación fue el principal estresor. El impacto de la Sequía × Defoliación fue de sinergia en la tasa de crecimiento relativa en ambas especies. Conclusión: Independientemente de la estrategia de uso de agua, en las primeras fases de desarrollo, el impacto de la sequía y defoliación se magnificó cuando interactuaron los estresores. La Sequía × Defoliación pueden limitar la regeneración de las especies dentro de los bosques, promoviendo la pérdida de la biodiversidad y el detrimento del funcionamiento de los ecosistemas.
