Bioclimatic Assessment and Thermal-Lighting Comfort in Vernacular Dwellings in the Jejenal District
No full textThis work addressed the issue of vernacular housing in the Jejenal area in the parish of San Isidro, with the aim of determining the climatic adversities such as high temperatures and relative humidity, which condition the capacity for thermal and light comfort of the population. A mixed-approach investigation was carried out that combines in situ measurements and computer simulations. The current conditions of these homes and their performance in relation to the environment were assessed, as well as the strengths and weaknesses that local construction strategies have been generating. The research work aims to make local architectural traditions efficient in order to improve the quality of life of the population that inhabits them through sustainable solutions. Although the homes in the Jejenal area formally represent a cultural heritage, there are important deficiencies, including the utility of the homes, as well as the overheating of the air inside them or an inefficient distribution of the windows. The results obtained demonstrate that, although native materials such as guadua cane or wood have great potential to offer sustainable solutions, their application entails correcting major deficiencies in construction techniques. Strategies such as the correct orientation of homes, the generation of shadows, as well as the use of passive ventilation are identified as key solutions for improving living conditions. This work proposes both construction guidelines, especially those that integrate traditional and bioclimatic knowledge, a model of sustainable rural housing that responds to the climatic and socioeconomic conditions of the region
Bibliometric analysis of bioremediation of hydrocarbon-contaminated soils in Ecuador 2019-2025
No full textIntroduction: biotechnology has developed techniques such as bioremediation, which seeks to restore contaminated soils through the use of microorganisms, plants, or organic amendments, reducing the concentration of contaminants without generating toxic secondary waste. It is necessary to compile, organize, and analyze research on bioremediation of hydrocarbon-contaminated soils in Ecuador.Objective: to analyze the current state of scientific production on bioremediation of hydrocarbon-contaminated soils in Ecuador during the period 2019-2025, through a bibliometric study.Method: scientific studies from the Scopus database were compiled and processed with the help of Biblioshiny (RDtudio) and Google Colab for analysis and visualization of key indicators: techniques, organisms, bioremediation strategies, publications by year, most cited studies, national affiliations, international collaborations, co-authorship networks, and journal quartiles.Results: they show sustained growth in scientific production, with a significant peak in 2022 and 2023. The most commonly used bioremediation techniques were bioaugmentation, phytoremediation, and the use of native microorganisms, with the genus Pseudomonas predominating, reflecting a preference for sustainable methodologies adapted to local conditions. The main national affiliations are public universities such as the University of the Armed Forces, the National University of Chimborazo, and the Technical University of Manabí. International collaborations, although few, are found in countries such as Mexico, Spain, Italy, Brazil, and Venezuela. Despite the progress, most research is published in low-quartile journals, which limits its international visibility.Conclusions: it is important to strengthen national and international collaboration networks and expand bibliometric analysis to include non-indexed documentary sources to achieve a more comprehensive view of scientific development in this area in the Ecuadorian context
State of more health of adults
No full textIntroduction: the functional valuation is one of the pillars of the valuation integral geriatric and it consists on the study of the old man's physical capacities in all its spectrum, from the tasks simpler motorboats and its car capacity taken care until the exercise and the independence in the environment. Objective: to characterize the state of the biggest population's of adults health, belonging to the Medical Clinic of the Family (CMF) Moncada, Policlínico Community Siblings Martínez Tamayo of the municipality Baracoa, during the period of April 2022 -to January 2022 Methods: he/she was carried out a descriptive, retrospective and traverse study. The study population was conformed by the biggest 100 adults (60 years and but) of both sexes, which completed the proposed inclusion approaches. The information was obtained through an interview to patient and relatives supported in a guide in correspondence with the variables to investigate (age, sex, biomedical, functional, psychological and social evaluation) and of the ambulatory clinical histories. The results were presented in distribution charts using as summary measure the number and percent, word processor Microsoft Word and Excel. Results: in the studied population the feminine sex prevailed on the masculine one. Starting from the 60 years they begin to appear the sensorial alterations and less than half of the studied old men they are functionally independent, while starting from the 80 years the dependence prevalence increases. The old men that are dependent for the ABVD are also it for the AIVD. Conclusions: the studied bigger population of adults has a good state of health
Pediatric radiology: a comprehensive approach to the diagnosis of lung injuries and congenital malformations
No full textIntroduction: The comprehensive study of cavitary lung lesions, congenital diaphragmatic anomalies, and pneumonia in children depends to a greater or lesser extent on chest X-rays. Objective: To describe the importance of X-rays in the accurate diagnosis of cavitary lung lesions and congenital anomalies in children. Development: Cavitary lesions—gas-filled spaces within an area of pulmonary consolidation or a mass/nodule—are linked to various benign and/or malignant pathologies. The diagnostic criteria depend more on CT scans than on X-rays. In the case of diaphragmatic hernias, X-rays are mainly used in cases that could not be diagnosed in the prenatal stage. For the differential diagnosis of pneumonia in pediatrics and its evolution, it is necessary to consult chest radiological studies, due to the variety of infectious agents. Conclusions: Chest radiography allows the location, extent, lobar or segmental involvement, and associated complications to be established; it can also provide guidance on the etiology, given the existence of atypical viral or bacterial pneumonias. Radiology is of great importance in the accurate diagnosis of cavitary lung lesions and congenital anomalies in the pediatric population and contributes significantly to the early diagnosis and effective management of these pathologies
Impacto del cambio de uso del suelo en la escorrentía superficial y la conductividad hidráulica: estudio de caso en la cuenca del río Baché, Huila (2004-2024)
No full textContextualization: The study analyzed surface runoff variations in the Baché River basin (Huila, Colombia) caused by land-use changes over three periods (2004, 2014, 2024).
Knowledge gap: Integrated analyses of how forest conversion to agriculture affected the hydrological response in volcanic soils (Andisols and Inceptisols) were lacking, despite covering 49.8% of the basin.
Objective: To evaluate the impact of changes in vegetation cover on hydraulic conductivity (Ks) and runoff, using hydrological models and satellite data.
Methodology: Landsat image processing (4/7/8, 30 m) in ArcGIS; digitalization of digital elevation models. HEC-HMS modeling was used to generate hydrological scenarios, and Ks was calculated, and flow rates were compared.
Results: Progressive reduction in Ks: 2.1 mm/h (2004) to 1.59 mm/h (2024); Increase in runoff: 899 m³/s (2004, 44.29% forest) to 1619 m³/s (2024, 70.9% agriculture), with a greater impact on volcanic soils near the drainage network.
Conclusions: Forest conversion has reduced soil water retention capacity by 47% in 20 years. The integrated GIS modeling approach has proven effective in assessing hydrological impacts, highlighting the need for volcanic soil conservation policies.

Reseña crítica del artículo: Merlo-Pinzón, J. A. (2020): Política y sufrimiento: notas desde Schopenhauer a la justificación de la dominación y la imposibilidad democrática. Revista Filosofía UIS, 19(2), 207-219
No full textSe pretende establecer un reseña crítica al escrito del profesor Merlo-Pinzón quien presenta en su artículo el argumento de la imposibilidad de la asociación política democrática, esto derivado de la idea de una Voluntad metafísica y absoluta que todo lo domina y devora, que se afirma en la objetivación del ser humano (su objetivación más desarrollada) bajo las formas del egoísmo, haciendo de las relaciones políticas una conjunción negativa y punitiva, muy distante de las visiones más felices desprendidas de la idea de un contrato social. La acotación polémica se perfilará desde una discusión en torno a elementos onto-políticos –si se permite el término– y, seguidamente, se hará una consideración acerca de la noción de compasión o caridad como bastión de lo político
La heterodoxia de la prensa carlista en la ultra periferia del Estado español: El caso del diario España (1897-1906) de las islas canarias en el contexto del «desastre del 98»
No full textIn this article, we propose to unravel the reasons for the long existential cycle, almost a decade (1897-1906), of the “Catholic-traditionalist” newspaper Spain in an information system as refractory to extremism as that of the Canary Islands. To this end, after valuing the temperance of the island’s ideological range in the face of the polarized pluralist system in force in the Iberian Peninsula, we ponder the effects of two successive centers of interest outside the editorial line of the newspaper that, in the context of the so-called “Disaster of 98”, favored its commercialization. We are referring, within the widespread demand for information raised by the Cuban issue, to the arrest and detention by military jurisdiction, a few months after Spain’s defeat against the United States, of the priest José Viera Martín, journalist of the newspaper in question, for his criticism of the Army; and, after this incident, the distancing of the initial ideological commitment and the campaigns launched by its director, Arturo Sarmiento, on the problems of the archipelago. The central sources of the research have been newspapers, consulted at the Museo Canario of Las Palmas de Gran Canaria, based on the mandatory content analysis.Neste artigo propomos desvendar as razões do longo ciclo existencial, de quase uma década (1897-1906), do jornal «católico-tradicionalista» Espanha num sistema de informação tão refratário ao extremismo como o das Ilhas Canárias. Para tal, depois de valorizar a temperança da gama ideológica da ilha face ao sistema pluralista polarizado vigente na Península Ibérica, ponderamos os efeitos de dois sucessivos centros de interesse fora da linha editorial do jornal que, no contexto do chamado «Desastre de 98», favoreceu a sua comercialização. Referimo-nos, dentro da ampla procura de informação suscitada pela questão cubana, à prisão e detenção por jurisdição militar, poucos meses depois da derrota de Espanha frente aos Estados Unidos, do padre José Viera Martín, editor do jornal em questão. , pelas críticas ao Exército; e, após este incidente, o distanciamento do compromisso ideológico inicial e das campanhas lançadas pelo seu diretor, Arturo Sarmiento, sobre os problemas do arquipélago. As fontes centrais da investigação foram os jornais, consultados no Museu das Canárias de Las Palmas de Gran Canaria, com base na obrigatória análise de conteúdo.En el presente artículo, nos proponemos desentrañar las razones del longevo ciclo existencial, casi una década (1897-1906), del diario «católico-tradicionalista»España en un sistema informativo tan refractario a los extremismos como el de las Islas Canarias. A tal fin, tras poner en valor la templanza del abanico ideológico isleño frente al sistema pluralista polarizado vigente en la península Ibérica, ponderamos los efectos de dos sucesivos centros de interés ajenos a la línea editorial del periódico que, en el contexto del llamado «Desastre del 98», favorecieron su comercialización. Nos referimos, dentro de la generalizada demanda de información que suscitaba la cuestión cubana, al arresto y reclusión por la jurisdicción militar, pocos meses después de la derrota de España contra los Estados Unidos, del sacerdote José Viera Martín, redactor del diario que nos ocupa, por sus críticas al Ejército; y, tras este incidente, al desmarque del compromiso ideológico inicial y a las campañas puestas en marcha por su director, Arturo Sarmiento, sobre la problemática del archipiélago. Las fuentes centrales de la investigación han sido las hemerográficas, consultadas en el Museo Canario de Las Palmas de Gran Canaria, sobre la base del preceptivo análisis de contenido
Psicología Humanista y Trabajo Social: Un binomio perfecto
No full textThe purpose of this work is to show the link that exists between two related disciplines that necessarily coincide, forming a perfect binomial. Social work and Humanistic Psychology, both have the challenge of accompanying the individual’s processes of change towards self-realization and self-determination in their lives in a respectful and empathetic way. To do this, a tour of humanistic psychology will be carried out; historical background, objectives and characteristics, from its birth to the present, as well as the review of the contribution of humanistic therapies to social intervention models, from the detection of the common aspects of both fields in the intrinsic value of the person. Social Work and Humanism are based on the satisfaction of the basic needs of the individual before reaching their maximum potential, as well as the means to do so, taking into account their unconditional acceptance and how cultural and social factors affect the personality and behavior of individuals. people. Social work and its professional identity focuses on the identification of unmet social needs and support in obtaining them in an empathetic and respectful manner of the individual through relationships, these being an end in themselves. Therefore, both disciplines go hand in hand in the helping relationship.El presente trabajo, tiene como finalidad mostrar el vínculo que existe entre dos disciplinas afines que coinciden de manera necesaria formando un binomio perfecto. El trabajo Social y la Psicología Humanista, ambas tienen el desafío de acompañar en los procesos de cambio del individuo hacia la autorrealización y autodeterminación en sus vidas de manera respetuosa y empática. Para ello se realizará un recorrido por la psicología humanista; antecedentes históricos, objetivos y características, desde su nacimiento hasta la actualidad, así como la revisión de la contribución de las terapias humanistas a los modelos de intervención social, desde la detección de los aspectos comunes de ambos campos en el valor intrínseco de la persona. Trabajo Social y Humanismo toman como base la satisfacción de las necesidades básicas del individuo antes de alcanzar su máximo potencial, así como los medios para ello, teniendo en cuenta su aceptación incondicional y como los factores culturales y sociales afectan a la personalidad y comportamiento de las personas. El Trabajo social y su identidad profesional se centrada en la identificación de necesidades sociales, no cubiertas y el acompañamiento en su obtención de una manera empática y respetuosa del individuo mediante las relaciones siendo estas un fin en sí mismo. Por lo que ambas disciplinas van de la mano en la relación de ayuda
