Published: February 2024

The aim of the article is to analyse the diversity of the level of eco-innovation in the EU Member States in the field of resource efficiency. For this purpose, the resource efficiency outcomes indicator and its sub-indicators were used. The study was prepared on the basis of data from the General Directorate for the Environment. Using positional statistical measures, an analysis of the diversification of the eco-innovation level of the European Union Member States in 2012-2021 was carried out, and the trends of changes in this differentiation were identified. The analysis showed that the difference between the level of eco-innovation in the indicators studied in the EU Member States does not decrease, and there is still a very large difference between the most and the least innovative countries. To date, we have not found this kind of research, so the research carried out fills the research gap in this area.
PHYLOGENETIC RELATIONSHIP BETWEEN RABIES VIRUS (RABIES LYSSAVIRUS) VARIANTS FROM TWO DIFFERENT HOST SPECIES
Authors: da Silva Schreiber Maicon , Fachinetto Juliana
Published: February 2024

Rabies is a fatal zoonotic disease that affects several mammals. Bats are recognized hosts of the rabies virus, and their main food source is the blood of other mammals, particularly cattle. During feeding, bats transmit the virus to cattle, which are victims of the disease, contributing to economic losses and increasing the risk of infection for humans. Based on this affinity in the rabies cycle between bats and cattle, the objective of this study was to analyze the phylogenetic relationships of rabies virus samples in cattle and bats. The G gene of the rabies virus was chosen for this study because it is directly related to the infection process. Nucleotide sequences of the viral G gene were selected from GenBank for samples obtained from infected cattle and bats. Maximum parsimony analyses were conducted using the Molecular Evolutionary Genetics Analysis software. The Maxima Parsimony tree indicated a phylogenetic relationship between the G genes of both hosts, indicating that the virus evolved from bats to cattle. Analysis of parsimoniously informative sites revealed that the viral G gene carried specific mutations in each host. Knowledge of the evolutionary relationships between the rabies virus and its hosts is critical for identifying potential new hosts and the possible routes of infection for humans.
Pedagogía de la Memoria en el Colegio Universitario Patagónico entre el 2015 y 2019
Authors:   , Álvarez Natalia
Published: February 2024

Este trabajo busca dar cuenta de las formas en las que se expresó la pedagogía de la memoria en la cultura escolar del Colegio Universitario Patagónico durante el periodo 2015-2019. En ese contexto, la implementación de políticas de memoria sufrió un repliegue que se expresó en la presencia de discursos negacionistas y relativistas respecto a la última dictadura cívico-eclesiástica-militar y el desfinanciamiento de los programas educativos que estaban orientados a fortalecer la memoria colectiva. Se parte de la premisa de que los emprendedores de memoria (Jelin, 2002) del Colegio Universitario Patagónico impulsan propuestas de enseñanza y aprendizaje singulares que buscan resignificar el deber de memoria en un contexto de negacionismo respecto al terrorismo de Estado. En este sentido, la oferta educativa preuniversitaria más austral del país se despliega en una zona donde el terrorismo de Estado y la guerra de Malvinas trascurrieron dejando testimonios, marcas de memoria, sobrevivientes y una voluminosa memoria colectiva del periodo que hacen posible conocer el pasado reciente con ciertas particularidades. De hecho, el Colegio fue fundado por el Consejo de Rectores de Universidades Nacionales en 1982. La Semana de la Memoria en el Colegio Universitario Patagónico es una experiencia de trabajo institucional que se funda en la pedagogía de la memoria y está atravesada por la historia regional. Las tensiones entre las cuales se analizará este trabajo se relacionan con cómo discurren los componentes de las prácticas locales de la escuela y las políticas estatales. Por este motivo, se emplea el enfoque cualitativo etnográfico como estrategia metodológica para abordar, por un lado, lo estatal-institucional, y, por otro, las identidades-subjetividades de la cultura escolar, reconociendo las zonas grises existentes entre la dictadura y la democracia del pasado reciente, y las implicancias de abordarlas.

excellent fracture exposure, but high rates of wound complications are seen. To lower the wound complications, a minimal incision approach at the
sinus tarsi has been proposed. The aim of this study was to observe the results of this approach. The study was conducted over a period of Methods:
7 years from January 2015 to January 2022. A total of 100 patients were included in this study. After admission to hospital, CT scan with coronal and
axial images were analysed. Fractures were classied according to Sander's Classication for calcaneal fractures. Clinical assessment was done
according to American Orthopaedic foot and Ankle society (AOFAS) hind foot score. Additionally, all patients were contacted and asked to return
for a research visit that included radiography and clinical examination. A tota Results: l of 100 patients were operated (male:67, female33). The
mean age of patients in our study was 42.5 years (male 40.5yrs, female 44.5yrs). 40% 0f cases had Excellent score, good in 47% and fair in 13% of
patient. Almost more than 80% returned to pre-injury status. Heel broadening (17.5%) and Subbular impingment (12.5%) were the most common
complications encountered during our study, although in almost all patients they were not a big problem clinically. The advantages of Conclusion:
sinus tarsi approach observed in our study include restoration of the dimensions of calcaleus to pre fracture levels through a small incision, avoiding
complications of lateral extensile approach. Thus it looks reasonable to use sinus tarsi approach for calcaneal fracture management when indicated.

Background: Nutrition in pregnancy refers to the nutrient intake and dietary planning that is undertaken before, during and after pregnancy.
Adequate protein intake is very important for the intrauterine growth of the foetus and the future wellbeing of the baby. Methods: This
observational cross-sectional study involves 500 patients who delivered at MGM Medical College and Hospital Aurangabad. A pre-designed
structured questionnaire was used in the form of one to one interview from which their protein and calorie intake was noted in structured format.
Pregnancy outcome was noted. Results: Out of 500 women, 30.6% patients had inadequate protein intake and 69.4% patients had adequate protein
intake. Formal education improves protein intake. Urban slum is having maximum number of patients with protein inadequacy. Vegetarian diet is
signicantly associated with inadequate protein intake. Inadequate protein intake and calorie intake is associated with preeclampsia, abruption,
FGR, intrauterine foetal demise and anaemia and is statistically signicant. Conclusion:Adequate protein intake in diet is modiable risk factor of
public health importance to prevent adverse birth outcomes.

Coronary artery anomalies are rare and those involving LMCA are further rare. Coronary artery anomalies are important as some anomalies carries
the risk for serious adverse event. Here we are discussing the case of 56-year-old male, who had presented with IWMI and angiography showed the
rare coronary anomaly. This patient had absent LMCA and small rudimentary vessel was present at the LMCA site, which was diffusely diseased
and cut off, which was lling retrogradely. Also, LAD like vessel, which was travelling in the anterior interventricular groove, was originating from
anomalous LCX, which was originating from right coronary sinus.

La reflexión sobre las prácticas pedagógicas de los profesores bajo la modalidad de Escuela Nueva es un reto que debe afrontarse con rigor. Los docentes de este modelo pedagógico son piezas claves para el alcance de los objetivos del sistema educativo nacional en la población rural, los cuales deben ser expertos en este modelo, para lograr su efectividad en la aplicación. Este estudio tuvo como objetivo general caracterizar las prácticas pedagógicas de docentes en torno a la escuela nueva en la educación rural. La investigación se fundamentó desde el enfoque cualitativo en un diseño etnográfico, específicamente microetnografía. Como resultado, se identificaron las dificultades en la práctica pedagógica desde la escuela activa, identificando docentes con débil conocimiento de la metodología, escasos recursos, precariedad de las sedes educativas, lejanía geográfica y escasa cualificación. Finalmente, este estudio detectó que actualmente se desarrolla un componente pedagógico hibrido entre la pedagogía tradicional y la escuela nueva.
Nuevos maestros de matemáticas desde el enfoque de la educación matemática crítica
Authors: Hernán Darío Quintana Blanco , Jiménez Espinosa Alfonso
Published: February 2024

La Educación Matemática Crítica (EMC) puede comprenderse desde las preocupaciones de entender la matemática como una construcción social. Se considera pertinente ampliar esta perspectiva en nuestros contextos educativos, ya que es un campo de investigación que se viene abriendo a nuevas posibilidades. Esta investigación tuvo como objetivo analizar los lineamientos curriculares de la Licenciatura en Matemáticas de la Universidad Pedagógica y Tecnológica de Colombia (UPTC), adicionalmente se tuvieron en cuenta las reflexiones suscitadas sobre la práctica de algunos docentes del Programa en la formación en EMC de nuevos maestros de matemáticas. La metodología adoptada es de tipo cualitativo con el fin de analizar los aspectos más significativos que conllevan a la formación crítica de los futuros profesionales en matemáticas. Los resultados permiten apreciar que desde la práctica docente y dentro del plan curricular de la Licenciatura, la formación de sujetos críticos y reflexivos se establece como eje fundamental, con capacidades de participación ciudadana en los aspectos que la complejidad social actual exige.
STEM+Ancestralidad: Hacia el incremento de la cultura científica y tecnológica, en poblaciones femeninas étnicas vallecaucanas

Published: February 2024

Las poblaciones femeninas afrodescendientes, indígenas y de otros grupos étnicos en Colombia y en Latinoamérica han estado relegadas de la participación en procesos de CTeI, Ciencia, Tecnología e Innovación. No obstante, en los últimos años se han incrementado los proyectos y programas que velan por la reducción de las desigualdades, la equidad de género y la educación de calidad, como lo plantean los objetivos de desarrollo sostenible del Programa de las Naciones Unidas para el Desarrollo (PNUD). Este artículo presenta el mapeo de las características, condiciones y estrategias pedagógicas implementadas, teniendo en cuenta la metodología STEM+Ancestralidad, que contribuye a incrementar la cultura científica en las niñas y adolescentes afro e indígenas del Valle del Cauca, el cual es un resultado del proyecto “Desarrollo de una estrategia que fortalezca la cultura en Ciencia, Tecnología e Innovación en niñas y mujeres adolescentes afrodescendientes, indígenas y comunidades étnicas del Valle del Cauca”, con recursos del Sistema Nacional de Regalías, presentado por la entidad territorial de la Gobernación del Valle del Cauca y con instituciones cooperantes como INFIVALLE, Universidad del Valle, Universidad Santiago de Cali y CUDES. El proyecto surge de la necesidad de incrementar las actividades de fomento de la ciencia, tecnología e innovación en niñas y mujeres adolescentes afrodescendientes, indígenas y comunidades étnicas en el departamento del Valle del Cauca. Para ello, se implementa la metodología STEM+Ancestralidad, en la formación de 360 niñas y adolescentes afro e indígenas, de seis (6) subregiones del Departamento, en un ejercicio pedagógico con metodología IEP e IAP, donde se integran los saberes ancestrales y el conocimiento tradicional con los científicos consuetudinarios. Para ello se capacitó a maestros, niñas y adolescentes en el diseño de proyectos de investigación provenientes de las necesidades de sus contextos. La mayoría de proyectos resultantes tienen un corte social etnográfico, atendiendo a la necesidad de preservar tanto los territorios como las prácticas culturales, sin perder de vista los conocimientos científicos. Es decir, la ciencia al servicio de la cultura.
La perspectiva de los docentes sobre los factores de riesgo escolar en centros de educación secundaria de la provincia de Albacete
Authors: González Berruga Manuel Ángel
Published: February 2024

Se presentan los resultados de una investigación descriptiva interpretativa sobre los factores de riesgo de las relaciones escolares en centros de Educación Secundaria de la provincia de Albacete. Se analiza la perspectiva de los docentes sobre las relaciones escolares desde la teoría de las comunidades profesionales de aprendizaje y se analizan las programaciones didácticas de departamento con la categoría de clasificación de Bernstein. Se observa una organización vertical, donde las decisiones sobre los elementos importantes del centro se toman por la dirección, los jefes de departamentos y el profesorado, en este orden, observando una falta de participación de estudiantes y familias. Los docentes no colaboran entre departamentos dando lugar a un currículum fragmentado. No existen diferencias notables entre centros de diferentes contexto socioeconómico y cultura, entre docentes de grupos ordinario y de mejora del rendimiento. Los docentes con menos experiencia presentan una percepción más favorable de las relaciones docentes.
Determinación de constructos sobre estrategias de enseñanza para desarrollar el razonamiento algebráico
Authors: Hernández Castaño Susana Del Pilar
Published: February 2024

El presente artículo da cuenta de una investigación que tuvo por intención determinar constructos teóricos asociados al razonamiento algebraico que favorecieran la comprensión del fenómeno tal como se presenta en determinados contextos. Aquí se asumió un proceso orientado desde el paradigma interpretativo, sustentado en el enfoque cualitativo, a través de la fenomenología como método, donde figuraron la codificación y categorización como procedimientos de análisis cuya información se obtuvo desde la aplicación de entrevistas y encuestas. De esto resultó el insumo que permitió la determinación de los constructos denominados «saber del docente» , «experiencias diarias» y «realidad curricular», así como los conocimientos, costumbres y prácticas de éstos en cuanto a las estrategias de enseñanza involucradas en el desarrollo del razonamiento algebraico; de donde fue posible concluir que si bien los docentes comprenden nociones generales en cuanto estrategias, estos sustentan sus percepciones y prácticas en representaciones subjetivas que destacan vacíos e imprecisiones, en torno al entramado conceptual sobre estrategias formativas, debido a la referencia indistinta que otorgan a componentes como métodos, actividades, técnicas y recursos.
