RESUMO: Entender aspectos da germinação de sementes de espécies nativas do Cerrado pode auxiliar na escolha de espécies a serem utilizadas na restauração de ecossistemas degradados. Portanto, o estudo teve como objetivo verificar o efeito de cápsulas biodegradáveis na germinação de sementes de três espécies arbóreas típicas de fisionomias florestais do Cerrado (Enterolobium contortisiliquum, Anadenanthera colubrina e Dipteryx alata). O experimento foi conduzido em casa de vegetação, com dois tratamentos: semeadura no interior de cápsulas biodegradáveis e semeadura direta na superfície do substrato. Duas sementes de cada espécie foram utilizadas por tratamento, as quais foram acomodadas em sacos plásticos com substrato arenoso oriundo da classe Neossolo Quartzarênico. Para cada tratamento, foram utilizados cinco blocos (repetições), com 20 sacos plásticos cada. A casa de vegetação teve condições controladas de temperatura e umidade relativa. Dentro das cápsulas, os resultados mostraram que as sementes de baru, angico-branco e tamboril apresentaram germinação de 97%, 42% e 12%, respectivamente. Por outro lado, na semeadura direta, a germinação foi de 15% para baru, 21% para angico-branco e 8% para tamboril. Os resultados indicam que o uso de cápsulas biodegradáveis favorece a germinação das espécies do Cerrado estudadas. Assim, tanto a utilização das cápsulas quanto as espécies elencadas são recomendadas em projetos de restauração ecológica.

ABSTRACT: A good grasp of the different facets of seed germination of the plant species native to the Cerrado will facilitate the selection of species that can be used to restore degraded ecosystems. Hence, the objective of the current study was to confirm the ways biodegradable capsules affect the germination of the seeds of three tree species typical of the physiognomies of the Cerrado forest (Enterolobium contortisiliquum, Anadenanthera colubrina and Dipteryx alata). The experiments, conducted in a greenhouse, included two treatments: seeding performed inside biodegradable capsules and direct seeding on the substrate surface. Two seeds from each of the species were sown in plastic bags containing the Quartzarenic Neosol class of substrates. Using five replicates for each treatment resulted in 20 plastic bags for each. The greenhouse conditions included controlled temperature and relative humidity. Inside the capsules, the findings revealed that the baru, angico-branco and tamboril seeds germinated at the rates of 97%, 42%, and 12%, respectively. However, during direct seeding, germination rates for baru, angico-branco and tamboril were 15%, 21% and 8%. From the findings, it is evident that when biodegradable capsules are used, the germination of all three Cerrado species investigated is favoured. Thus, both capsules and the cited species can be recommended for projects of ecological restoration.

Abstract The technique of bending wood by vaporization presents itself as a viable option for curvilinear structural projects, such as gridshells. Coniferous woods are often used in roof structures because, in addition to the desired relationship between mechanical strength and density, they allow the complete treatment of the cross-section of the piece. However, characteristics such as the predominance of sapwood or heartwood and the presence of defects are variables that affect structural performance. The aim of this study was to evaluate the bending limit of Acrocarpus laxinifloius (Indian cedar) veneers with a bending radius of 21 cm at different thicknesses. The impact of the predominance of sapwood or heartwood and the presence of defects on the bending strength was also investigated. The literature indicates that plastic flexibilization by steam occurs at 100°C, with 2.4 minutes for each millimeter of lamella thickness, which were the parameters considered in this study. The statistical analysis indicated a thickness limit of 8 mm for the lamellae to bend and the greater presence of sapwood or heartwood, as well as wood defects, did not significantly affect the bending force. projects gridshells because density crosssection cross section piece However performance Indian cedar 2 thicknesses investigated 100C C 100 100°C 24 4 2. force 10 1

Resultados: aplicando este método a un portafolio conformado de ocho opciones europeas listadas sobre el índice SPX, encontramos que la cobertura conformable genera predicciones más precisas, en promedio, que la cobertura tradicional. Limitaciones: este método es aplicable solamente a la cobertura delta (hedging) de opciones europeas. Originalidad: esta es la primera aplicación exitosa del cálculo conformable a la cobertura delta en opciones europeas. Conclusiones: la aplicación del cálculo conformable permite mayor flexibilidad en la aproximación local implícita en la cobertura delta de portafolios de acciones europeas y se ofrece como una metodología novel y de mayor precisión que la tradicional.

Abstract Objective: we aim to develop a method for delta hedging portfolios of European options based on the theory of conformable calculus which improves accuracy of risk management of listed options in a first-order approximation. Methodology: we allow the time derivative in the classic Black-Scholes-Merton model to have a fractional order 0 ≤ α ≤ 1 and calculate the corresponding delta of a portfolio of listed options as a function of this conformable parameter. Results: applying this method to a portfolio consisting of eight European options on the SPX index, we find that conformable delta hedging offers more accurate average predictions than classical delta hedging. Limitations: this method is applicable for delta hedging in European options only. Originality: this is the first successful application of conformable calculus to delta hedging in European options. Conclusions: application of Conformable Calculus allows for a greater flexibility in the local approximation to price in delta-hedging European options and offers a new and more precise methodology to this objective.

Resumo A produção de tintas utilizando resíduos de beneficiamento de granito e mármore é uma nova alternativa para contribuir com o desenvolvimento sustentável na construção civil. Entretanto, a carência de estudos sobre a composição e o desempenho dessas tintas inviabiliza a disseminação desse novo material de construção. Logo, este estudo tem como objetivo investigar a composição dessas tintas utilizando ferramentas estatísticas para obter produtos com desempenho compatível com regulamentações técnicas e tintas comerciais. As formulações de tintas foram definidas através de um planejamento de misturas quaternárias. O teor de sólidos, pH, viscosidade, poder de cobertura e resistência à abrasão foram determinados para todas as amostras. As tintas produzidas com resíduos de granito apresentaram melhor poder de cobertura e resistência à abrasão, pois o resíduo de granito apresenta granulometria mais fina, além de ser predominantemente composto por sílica. Por fim, as tintas produzidas neste estudo e as tintas comerciais apresentaram comportamento semelhante, o que corrobora com o aproveitamento do resíduo do processamento de rochas ornamentais na produção de tintas. civil Entretanto Logo quaternárias sólidos pH viscosidade amostras fina sílica fim semelhante

Abstract The production of paints using waste from granite and marble processing is a new alternative to contribute to sustainable development in civil construction. However, the lack of studies on the composition and performance of these paints makes the dissemination of this new construction material unfeasible. Therefore, this study aims to investigate the composition of these paints using statistical tools to obtain products with performance compatible with technical regulations and commercial paints. The paint formulations were defined through a quaternary mixture planning. The solids content, pH, viscosity, hiding power, and abrasion resistance were determined for all samples. The paints produced with granite waste showed better hiding power and abrasion resistance, as granite waste has a finer granulometry, in addition to being predominantly composed of silica. Finally, the paints produced in this study and the commercial paints showed similar behavior, which supports the use of waste from the processing of ornamental rocks in paint production. However unfeasible Therefore planning content pH viscosity samples granulometry silica Finally behavior

Abstract Child Sexual Abuse (CDA), an uncomfortable reality for humanity whose numbers rise every year. Given the demands established by international organizations, this research represents a first approach to the phenomenon through a documentary and comparative review to identify CSA prevention programs developed in Mexico and other countries in search of granting Children and Adolescents (C&A) a dignified life and promote their rights to integrity. A qualitative study was implemented through a review of materials using documentary review as an analysis technique. Once the pertinent literature was located, the documentary record was carried out under a methodological process and the corresponding analysis was elaborated through a comparative technique. Within the results of the research, sexual education is insufficient at the basic level even though the SEP has provided material for its prevention without sufficient coverage and the school has become responsible for implementing programs that meet the needs of the context. In the present work, programs aimed at students, parents, teachers and civil organizations whose objectives are to inform, detect risk situations, promote health and provide self-care tools are identified.

Ante las demandas establecidas por las organizaciones internacionales, esta investigación representa una primera aproximación al fenómeno a través de una revisión documental y comparativa para identificar los programas de prevención de ASI desarrollados en México y otros países en busca de otorgar a Niños, Niñas y Adolescentes (NNA) una vida digna y se promuevan sus derechos a la integridad. Se implementó un estudio cualitativo por medio de una revisión de materiales utilizando como técnica de análisis la revisión documental. Una vez localizada la literatura pertinente se procedió el registro documental bajo proceso metodológico y mediante una técnica comparativa se elaboró el análisis correspondiente. Dentro de los resultados de la investigación, la educación sexual resulta insuficiente en el nivel básico a pesar de que la SEP ha dotado de material para su prevención sin cobertura suficiente y la escuela se ha convertido en responsable de implementar programas que atiendan las necesidades del contexto. En el presente trabajo, se identifican programas dirigidos a alumnos, padres, maestros y organizaciones civiles cuyos objetivos son informar, detectar situaciones de riesgo, promover la salud y otorgar herramientas de autocuidado.

Abstract Surface Urban Heat Islands (SUHI) are formed through processes that include decreasing vegetation and increasing materials that are more conductive to heat. To investigate this phenomenon, the objective of this work is to comparatively verify the surface temperature and geospatial indicators to analyze environmental variation in the city of São Paulo, Brazil. The study method is remote sensing, with data from the Landsat 8 satellite over a ten-year timeframe. The variables include land cover, the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Built-up Index (NDBI), and land surface temperature (LST), thereby obtaining the Urban Thermal Field Variation Index (UTFVI) and estimating SUHI formation. The results allowed for the presentation of a progression of variables, highlighting the recurrent formation of SUHI in the central and eastern regions of the city of São Paulo, Brazil. Conversely, the southern and extreme northern districts exhibited the best NDVI indices and low LST values.

Abstract Introduction. The main control measure for brown spot (BS) caused by Septoria glycines is through the application of foliar fungicide. However, the management of the disease could be accomplished through cultural and genetic practices. Objective. To analyze the evolution of BS in soybean under different production systems. Materials and methods. This study was conducted for two consecutive years (2020 and 2022), in Pergamino, Buenos Aires, using the soybean cultivar DM46i20. The management variables studied were cover crops (CC), rotations (Rt), and timing of foliar fungicide application (MAFF). The evaluated pathometric variable was the area under the progress curve of plant height with symptoms (ABCPAPS), and the quantitative physiology variable was grain yield (R) in kg/ha. Results. Agronomic management practices had a significant effect (p≤0.05) on R and ABCPAPS. CC and MAFF were independent variables and showed a significant response (p<0.0001) on R. On the other hand, there was a significant triple interaction (p<0.0001) among CC, Rt, and MAFF for ABCPAPS, and therefore, the data were explained based on this relationship. Conclusions. The implementation of cover crops, crop rotations, and foliar fungicide significantly reduced (p≤0.05) the evolution of BS in soybean cultivation. There was a significant negative correlation (p≤0.05) between soybean yield and the area under the progress curve of the plant height with BS symptoms.

Abstract Introduction. Sweet potato (Ipomoea batatas (L) Lam.) is sensitive to weed competition, and chemical control in Costa Rica is challenging due to limited local information on herbicide selectivity. Objective. To determine the selectivity of six herbicides applied at different stages of development to Criollo sweet potatoes and their effect on coverage, biomass, and crop yield. Materials and methods. Between August and December 2021, three experiments were conducted at the Fabio Baudrit Moreno Agricultural Experimental Station, Universidad de Costa Rica, Alajuela, Costa Rica. Herbicides were applied (in kg a.i. ha-1) as follows: a) Experiment 1: 0.36 of metribuzin, 1.50 of pendimethalin, 0.48 of clomazone, 0.075 of halosulfuron, 1.00 of linuron, and 1.25 of metolachlor, applied six days after planting (dap) in a randomized block design with four repetitions; b) Experiment 2: 1.00 of linuron and 0.36 of metribuzin 0.36, applied at -1, 15 and 30 dap, in a randomized block design with a 2x3 factorial arrangement and three repetitions; and c) Experiment 3: 0.075 of halosulfuron and 0.36 of metribuzin, mixed with 0.125 of fluazifop-p-butyl in a randomized block design with three repetitions. Weeding was performed at 15 and 30 dap in all cases. Results. Root yield was not affected in any of the three experiments. Experiment 1: Only halosulfuron caused mild damage to the plants; no herbicide affected above-ground biomass production. Experiment 2: Only linuron and metribuzin applied at 15 and 30 dap caused mild damage. Experiment 3: The mixtures caused temporary damage to the plants. Conclusions. The evaluated herbicides were selective to the Criollo sweet potatoes, and did not affect the yield of marketable storage roots. Only halosulfuron caused mild damage in all application forms, and metribuzin and linuron only in late applications.

Abstract Introduction. Wild species are important in the ecosystem, and their preservation requires the development of effective techniques. Objective. To determine the in situ and ex situ germination characteristics and field growth of Porcelia mediocris N.A. Murray and Compsoneura trianae Warb. in Arosemena Tola, Napo, Ecuador. Materials and methods. The study was carried out between 2019 and 2020, with seeds collected from the primary forest of P. mediocris and C. trianae. Germination tests were conducted in a greenhouse and in the primary forest, measuring seed emergence, tray growth, and performing an analysis of variance between the testing sites. Seedlings were transplanted into three different soil covers at the Amazon Center for Teaching, Research, and Productivity, with measurements taken for height, stem diameter, number of leaves, and survival. Growth curves were created, and an analysis of variance was performed on the final growth measurements among the different soil covers. Results. For P. mediocris, greenhouse-grown plants showed fewer days to the emergence (67.6), but those grown under guaba cover had a greater height (19.45 cm) and germination percentage (70 %) at end of the trial. For C. trianae, plants grown at the collection site had greater height (13.38 cm) and number of leaves at the end of the evaluation. Field growth did not show differences between soil covers, with survival rate of 47 % for P. mediocris and 75 % for C. trianae. Conclusions. P. mediocris showed better germination percentages under guaba cover, while C. trianae exhibited greater growth in the primary forest, with the germination site not affecting post-transplant growth for either species.

P. mediocris reportó mejores porcentajes de germinación en la cobertura guabas y C. trianae tuvo mayor crecimiento en el bosque primario, sin que el sitio de germinación influyera en el crecimiento posterior al trasplante en ambas especies.

ABSTRACT The mangroves are exposed to threats such as sea level rise, coastal erosion, increase in the frequency and intensity of extreme events, in addition to socioeconomic pressures. This study aimed to carry out a vulnerability and risk climate analysis for the Colombian mangrove socioecosystem. 22 threat indicators, eight of sensitivity and 18 of adaptive capacity were used, and through multivariate numerical analysis, the vulnerability and climate risk indices for Colombian Pacific and Caribbean mangroves were generated. The mangroves that presented the highest risk in the Caribbean were located in the Manaure, Tubará and, Puerto Escondido municipalities, while in the Pacific these high-risk areas were located on the southern coast in the Olaya Herrera, Francisco Pizarro, and La Tola municipalities, and in the northern coast in the Bahía Solano municipality. The threat indicators that captured the greatest variability in the analysis were: sea level rise, change in the coastline, change in water supply, change in mangrove coverage due to change in the coastline, change in temperature and precipitation due to El Niño and La Niña, and human footprint. These results are input for climate management of mangroves in Colombia and will contribute to the National Mangrove Program. Likewise, it can contribute to the National Mangrove Restoration Plan, the Nationally Determined Contribution of Colombia (NDC), the Long-Term Climate Strategy of Colombia E 2050, and the Territorial Plans for Climate Change Adaptation of the states and municipalities.

RESUMEN Los manglares están expuestos a amenazas como el aumento del nivel del mar, la erosión costera, el aumento de la frecuencia e intensidad de eventos extremos, además de presiones socioeconómicas. Este estudio tuvo como objetivo realizar un análisis de vulnerabilidad y riesgo climático para el socioecosistema de manglar de Colombia. Se utilizaron 22 indicadores de amenaza, 8 de sensibilidad y 18 de capacidad adaptativa; mediante un análisis numérico multivariado se generaron los índices de vulnerabilidad y riesgo climático para los manglares del Pacífico y del Caribe de Colombia. Los manglares que presentaron mayor riesgo en el Caribe se ubicaron en los municipios de Manaure, Tubará y Puerto Escondido, mientras que en el Pacífico estas áreas de alto riesgo se ubicaron en la costa sur, en los municipios de Olaya Herrera, Francisco Pizarro y La Tola, y en la costa norte de Bahía Solano. Los indicadores de amenaza que capturaron la mayor variabilidad del análisis fueron: el aumento del nivel del mar, el cambio en la línea de costa, el cambio en la oferta hídrica, el cambio en la cobertura de manglares por cambio en la línea de costa, el cambio en la temperatura y la precipitación debido a El Niño y La Niña, y la huella humana. Estos resultados son un insumo para la gestión climática de los manglares en Colombia y contribuirán al Programa Nacional de Manglares. Asimismo, podrán contribuir al Plan Nacional de Restauración de Manglares, la Contribución Nacionalmente Determinada de Colombia (NDC), la Estrategia Climática de Largo Plazo de Colombia E2050, y los Planes Territoriales de Adaptación al Cambio Climático de los departamentos y municipios.

Summary: The fraction of vegetation cover (FVC) and the Leaf Area Index (LAI) are biophysical variables closely related to the evapotranspiration rate of crops and their biomass production. Despite their importance, they are usually not measured directly due to their time-consuming and costly nature; however, they can be estimated on a large scale and near-real-time using spectral information captured in satellite images, although this requires prior validation at the field level. Simple linear regression models were developed and validated using 13 vegetation indices (VI) related to LAI and FCV in alfalfa (Medicago sativa). Three spectral information sources were used: (i) reflectance to derive the VI; (ii) digital photographs processed with the Canopeo application to estimate FVC; and (iii) direct LAI measurements using a ceptometer. Six field samples were taken between March and June, 2020 in four alfalfa plots located in Palmar de Bravo, Puebla, Mexico. To evaluate each VI, the determination coefficient (R2) and the root mean square error (RMSE) were used. We found that the most suitable VI for estimating FVC was the VIgreen (Green Vegetation Index, R2 =0.987 and RMSE = 0.093). For the LAI, the VI that performed best was the NDVI (Normalized Difference Vegetation Index, R2 = 0.935 and RMSE = 0.746). The results showed the suitability and practical utility of spectral information for estimating biophysical variables in alfalfa cultivation and their monitoring.

Resumen: La fracción de cobertura vegetal (FCV) y el índice de área foliar (IAF) son variables biofísicas relacionadas estrechamente con la tasa de evapotranspiración de los cultivos y su producción de biomasa. A pesar de su importancia, usualmente no se miden de manera directa debido al tiempo invertido y costo; sin embargo, se pueden estimar a gran escala y en tiempo casi real mediante información espectral captada en imágenes de satélite, pero esto requiere de su validación a nivel de campo. Se desarrollaron y validaron modelos de regresión lineal simple utilizando 13 índices de vegetación (IV) relacionados con el IAF y la FCV en alfalfa (Medicago sativa). Se usaron tres fuentes de información espectral: (i) La reflectancia para derivar los IV; (ii) fotografías digitales procesadas con Canopeo para estimar la FCV; y (iii) mediciones del IAF utilizando un ceptómetro. Se realizaron seis muestreos de campo entre marzo y junio de 2020, en cuatro parcelas de alfalfa situadas en Palmar de Bravo, Puebla, México. Para evaluar cada IV, se utilizó el coeficiente de determinación (R2) y la raíz del cuadrado medio del error (RCME). Se encontró que el IV más apropiado para estimar la FCV fue el VIgreen (Green Vegetation Index, R2 = 0.987 y RCME = 0.093). En el caso del IAF, el IV que presentó el mejor desempeño fue el Normalized Difference Vegetation Index (NDVI), R2 = 0.935 y RCME = 0.746). Los resultados mostraron la aptitud y utilidad práctica de la información espectral para estimar las variables biofísicas en el cultivo de alfalfa y su monitoreo.

Resumen Este estudio, se centra en la cobertura forestal de tres distritos en el ámbito urbano de la provincia de Andahuaylas, región Apurímac en Perú, la cual afronta problemas de deforestación. El objetivo fue determinar la cobertura forestal en el área urbana de la provincia de Andahuaylas hasta el 2030, para la revelación de los escenarios futuros de la cobertura forestal, contribuyendo al desarrollo de la planificación urbana y a la creación de ciudades sostenibles. Para el área de estudio, se utilizaron datos registrados entre los años 2017-2023, a partir de las imágenes NDVI del portal Sentinelhub. Permitiendo disponer de información de bosques tropicales y templados; arbustos y pastizales; zonas áridas de roca; áreas urbanas o artificiales que han cambiado como consecuencia del proceso de urbanización. Se determinaron las superficies de bosque en el área de estudio. Posteriormente se utilizó la regresión lineal con un p valor = 0,046, alcanzando un R2 de 0,583 en un rango medio, logrando estimar los escenarios futuros del bosque al 2030. Se concluye que la tendencia es decreciente en la cobertura forestal en 26,50% al año 2030.

Absttract This study focuses on the forest cover of three districts in the urban area of the province of Andahuaylas, Apurímac region, Peru, which is facing deforestation problems. The objective was to determine the forest cover in the urban area of the province of Andahuaylas until 2030, to reveal future scenarios of forest cover, contributing to the development of urban planning and the creation of sustainable cities. For the study area, data recorded between the years 2017-2023 were used, based on NDVI images from the Sentinelhub portal. This allowed for the availability of information on tropical and temperate forests, shrubs and grasslands, arid rock zones, and urban or artificial areas that have changed due to the urbanization process. The forest surfaces in the study area were determined. Subsequently, linear regression was used with a p-value = 0,046, reaching an R2 of 0,583 in a medium range, managing to estimate future forest scenarios by 2030. It is concluded that the trend is decreasing in forest cover by 26,50% by the year 2030.

El convenio tiene como principal objetivo asegurar la asistencia paliativa a todos los usuarios de los prestadores involucrados con los principios fundamentales de calidad, equidad y accesibilidad, siguiendo los lineamientos del Plan Nacional de Cuidados Paliativos del Ministerio de Salud Pública de Uruguay. El objetivo es describir y analizar la experiencia de la implementación del primer modelo de complementación público-privado del país en Cuidados Paliativos (CP). Metodología: Estudio descriptivo analítico, retrospectivo que incluye datos de los primeros siete años de funcionamiento del convenio. Resultados: El convenio de complementación público-privado en el Departamento de San José, permitió la creación de un equipo interdisciplinario que asistió en forma continua a 1422 pacientes provenientes de zonas urbanas y rurales, portadores de diversas patologías. La cobertura departamental de CP aumentó de forma significativa, pasando de 24 % en 2014 a 57% en 2021. Estos resultados se lograron implementando un modelo de asistencia paliativa que asegura la continuidad asistencial en internación, consultorio y domicilio, que permitió respetar la autonomía del paciente, logrando el fallecimiento de 67% de los pacientes en su hogar. La satisfacción de usuarios y familiares de la asistencia brindada fue evaluada como muy buena. Conclusiones: El convenio de complementación resultó ser una herramienta eficiente para favorecer el acceso a CP, evitando la superposición de equipos en la asistencia domiciliaria en todo el departamento de San José.

Abstract: Introduction: At the beginning of 2015, the public-private complementarity agreement was implemented between the two main providers of the Department of San José Uruguay: AMSJ and ASSE San José, thus forming the Departmental Unit of Palliative Medicine of San José (UDMP). The main objective of the agreement is to ensure palliative care to all users of the providers involved, with the fundamental principles of quality, equity and accessibility, following the guidelines of the National Palliative Care Plan of the Ministry of Public Health of Uruguay. The objective is describe and analyze the experience of implementing the country's first public-private complementation model in Palliative Care (PC). Methodology: Descriptive, analytical, retrospective study that includes data from the first seven years of operation of the agreement. Results: The public-private complementation agreement in the Department of San José allowed the creation of an interdisciplinary team that continuously assisted 1,422 patients from urban and rural areas, with various pathologies. Departmental CP coverage increased significantly, from 24% in 2014 to 57% in 2021. These results were achieved by implementing a palliative care model that ensures continuity of care in hospitalization, office and home, which allowed the patient's autonomy to be respected, achieving the death of 67% of patients at home. The satisfaction of users and family members with the assistance provided was evaluated as very good. Conclusions: The complementation agreement turned out to be an efficient tool to promote access to CP, avoiding the overlap of teams in home care throughout the department of San José.

ABSTRACT Objective : To sociodemographically characterize patients with Mood Disorders in a Mental Health Institution in Montería, Córdoba - Colombia, and correlate this diagnosis with variables of interest. Materials and Methods: This descriptive, retrospective-longitudinal study correlated sociodemographic variables with Mood Disorders in 729 hospitalized patients in an Institution of Mental Health, originating from municipalities in the department of Córdoba, during the period 2012-2021. Results: Men with an average age of 23 years presented a higher frequency of Mood Disorders (n=689) compared to women (n=40). The majority of patients originated from municipalities such as Montería, Puerto Libertador, Valencia, Tierralta, and Canalete. Montería, being the municipality with the largest population, showed a lower prevalence. Factors such as place of origin, lack of family support, and stress influenced relapses, with a decrease in hospitalizations of these patients during the COVID-19 pandemic. Conclusion: There is a correlation between sociodemographic variables such as the place of origin in the department of Córdoba, lack of family support, and stress as determinants for the occurrence of Mood Disorders diagnosis in patients from municipalities characterized by high and medium levels of violence, low educational coverage, and multifunctional poverty in vulnerable populations.
