Resumen La carretera Puyo-Tena es propensa a deslizamientos de tierra debido a la geodinámica, geomorfología y materiales geológicos de la zona (afloramientos y estratos inestables). En los últimos años, este problema ha provocado de forma persistente la inutilización parcial o total de la carretera en numerosas ocasiones. El objetivo de la investigación fue generar un modelo cartográfico de susceptibilidad a deslizamientos a partir de variables como la pendiente, las formaciones geológicas, la cobertura y uso de la tierra, así como las distancias a fallas, carretera y ríos. El grado de incidencia de deslizamientos se estimó como la combinación lineal de las variables ponderadas mediante el proceso de jerarquía analítica. La importancia de este método semicuantitativo radica en su capacidad para desagregar un problema de decisión complejo en un modelo de decisión más simple y coherente. El modelo cartográfico resultante se reclasificó en cinco categorías de susceptibilidad: muy baja, baja, moderada, alta y muy alta. Los resultados mostraron que 17 km de los 80 km de la carretera Puyo-Tena tienen una alta probabilidad a deslizamientos, lo que equivale a 21,25% de la carretera. Además, dentro de este porcentaje, se determinó que existen quince regiones con alta probabilidad de deslizamientos debido a su ubicación en zonas con fuertes pendientes, litología porosa y permeable, gran cantidad de ríos y suelos agrícolas. Para la verificación del modelo se utilizó el área bajo la curva (en inglés AUC) de la característica operativa del receptor (en inglés ROC). Los resultados de la verificación mostraron que el modelo cartográfico para el área de estudio tiene un valor de precisión de 83,7%. El modelo cartográfico de susceptibilidad a deslizamientos permitirá tomar las decisiones pertinentes para mitigar eventos potenciales que puedan poner en peligro a transportistas, bienes materiales y residentes de la zona.

Abstract The Puyo-Tena roadway is prone to landslides due to the geodynamics, geomorphology, and geological materials of the area (unstable outcrops and strata). In recent years, this problem has persistently caused the road to be partially or completely disabled on numerous occasions. The objective of the research was to generate a cartographic model of landslides susceptibility based on variables such as slope, geological formations, land cover and land use, as well as distances to faults, road, and rivers. The degree of landslides incidence was estimated as the linear combination of the weighted variables using the analytic hierarchy process. The importance of this semi-quantitative method lies in its ability to break down a complex decision problem into a simpler and more coherent decision model. The resulting cartographic model was classified into five susceptibility categories: very low, low, moderate, high, and very high. The results showed that 17 km out of the 80 km of the Puyo-Tena roadway have a high probability of landslides, which is equivalent to 21.25% of the road. Furthermore, within this percentage, it was determined that there are fifteen regions with a high probability of landslides due to their location in areas with steep slopes, porous and permeable lithology, a large number of rivers, and agricultural soils. The area under the curve (AUC) of the receiver operating characteristic (ROC) was used for model verification. The verification results showed that the cartographic model for the study area has an accuracy value of 83.7%. The cartographic model of landslide susceptibility will enable relevant decisions to be made to mitigate potential hazards that may endanger transporters, material goods, and residents of the area.

Abstract This article explores why the Andean Community of Nations (CAN) has failed to achieve concrete regional security strategies for member countries. The research uses the English School of International Relations approach that considers security a value or a "primary institution", like territoriality, sovereignty, equality, and market; therefore, agendas and discussions within the regional group should include security proportionally. Through a frequency analysis, the study reviewed 342 decisions adopted by the CAN during 2006-2020. The results show that the community is still consolidating its structure. Although CAN has a broad technical agency and a scheme dedicated to strengthening the common market, its system of primary institutions is weak. In this sense, decisions on security are insufficient.

Resumen Este artículo indaga por qué la Comunidad Andina de Naciones (CAN) no ha logrado estrategias regionales concretas de seguridad para los países miembros. Se parte del enfoque de la escuela inglesa (EI) de las relaciones internacionales, que considera que la seguridad es un valor o una “institución primaria”, como lo son territorialidad, soberanía, igualdad y mercado; por lo que debería incluirse en las agendas y discusiones del grupo regional en igual proporción. Se estudiaron 342 decisiones adoptadas por la CAN en el período de 2006-2020 mediante un análisis de frecuencias. Se concluye que la comunidad se encuentra en construcción, tiene una amplia agencia técnica, una estructura dedicada al fortalecimiento del mercado común, pero su sistema de instituciones primarias es débil. En este sentido, las decisiones sobre la seguridad son insuficientes.

ABSTRACT In order to achieve the objectives set out in its National Economic and Social Development Plan through 2030, Cuba needs to have a solid, diversified, articulated and complementary productive structure. It represents a challenge for the country to make the changes foreseen in the Conceptualization of the Cuban economic and social development model to adapt the current dynamics and requirements of international economic development. The objective of the paper is to evaluate the current productive structure, measuring the relative importance and complementarity of the sectors in national economy, based on indicators of the National Accounts System. The main results reflect sectoral imbalances and small sectoral complementarity, low productive linkages, asymmetries development of provinces, low complexity exportable products with limited added value.

Abstract Substations are key facilities within an electrical system, untimely failures tend to cause low quality and negative effects on the electrical supply. An early indicator of potential electrical equipment failure is the appearance of hot spots; therefore, its detection and subsequent programmed correction avoids incurring in major failures and unnecessary operation stops. In this research, 64 experiments of the YOLOv5 algorithm were carried out, with the purpose of proposing an automated computer vision mechanism for the detection of hot spots in thermal images of electrical substations. The best results show a mAP value of 81.99%, which were obtained with the YOLOv5m algorithm and the transfer learning application. These results leave a basis to deepen and improve the performance of the algorithm by varying other hyperparameters to those considered in this study.

Resumen Las subestaciones son instalaciones clave dentro de un sistema eléctrico; las fallas intempestivas tienden a causar baja calidad y efectos negativos del suministro eléctrico. Un indicador temprano de posibles fallas en los equipos eléctricos es la aparición de puntos calientes; por lo que su detección y posterior corrección programada evita incurrir en fallas mayores y paradas de operación innecesarias. En esta investigación se realizaron 64 experimentos del algoritmo YOLOv5, con la finalidad de proponer un mecanismo automatizado de visión por computadora para la detección de puntos calientes en imágenes térmicas de subestaciones eléctricas. Los mejores resultados muestran un valor mAP de 81,99 %, los cuales se obtuvieron con el algoritmo YOLOv5m y la aplicación de transfer learning. Estos resultados dejan una base para profundizar y mejorar el desempeño del algoritmo, variando otros hiperparámetros a los considerados en el presente estudio.

Resumo: O manuscrito procura demonstrar o valor formativo do movimento corporal nos processos de mediação pedagógica das habilidades matemáticas dos estudantes no ensino fundamental, o que constitui um processo de pesquisa realizado com o corpo docente do Sistema Educacional Sancti Spíritus, localizado no cantão de Esparza, na província de Puntarenas, Costa Rica. A pesquisa está embasada nos princípios teóricos que mostram que o movimento corporal constitui um elemento central da aprendizagem na infância e contribui para o fortalecimento integral das capacidades e habilidades cognitivas, psicomotoras e sociais. A abordagem qualitativa utilizada na seleção dos instrumentos e análise da informação recolhida permite concluir que, no grupo de participantes, o movimento corporal como recurso de mediação de competências matemáticas é raro, razão pela qual surge a necessidade de abandonar a concentração da aprendizagem nas capacidades de memorização e repensar as formas como a mediação pedagógica da disciplina é assumida a partir de um currículo aberto, dinâmico, criativo, eficaz e de qualidade, com uma abordagem pedagógica inovadora que responda aos princípios de uma educação transformadora, que a partir do movimento corporal (entendido como habilidades naturais para pular, virar, andar, correr, manter o equilíbrio, a coordenação, bem como a capacidade de concentração), faz com que cada estudante seja protagonista de sua aprendizagem, possibilitando sua unificação física, emocional e cognitiva.

Resumen: Este artículo busca demostrar el valor formativo del movimiento corporal en los procesos de la mediación pedagógica de las habilidades matemáticas del estudiantado de educación primaria, el cual constituye un proceso investigativo realizado con la población docente del Sistema Educativo Sancti Spíritus, ubicado en el cantón de Esparza, de la provincia de Puntarenas, Costa Rica. La investigación parte de principios teóricos que evidencian que el movimiento corporal constituye un elemento central del aprendizaje en la infancia y contribuye al fortalecimiento integral de las capacidades y habilidades cognitivas, psicomotoras y sociales. El enfoque cualitativo utilizado en la selección de los instrumentos y análisis de la información recolectada permite concluir que, en el grupo de participantes, el movimiento corporal como recurso para la mediación de las habilidades matemáticas es poco frecuente; por lo que se plantea la necesidad de abandonar la concentración del aprendizaje en las capacidades de memorización y el replanteamiento en las formas como se asume la mediación pedagógica de la asignatura desde un currículo abierto, dinámico, creativo, eficaz y de calidad. Esto con un en- foque pedagógico innovador que responda a los principios de una educación transformadora, la cual, desde el movimiento corporal (entendido como las capacidades naturales de saltar, dar vueltas, caminar, correr, mantener el equilibrio, la coordinación y la habilidad para concentrarse), convierta a cada estudiante en protagonista de su aprendizaje, posibilitando su unificación física, emocional y cognitiva.

Abstract: This paper aims to demonstrate the formative value of physical movement in pedagogical mediation processes of mathematical skills in elementary school students. This research was conducted with the faculty of the Sancti Spíritus Educational System, in the canton of Esparza, province of Puntarenas, Costa Rica. The research is based on theoretical principles that prove that physical movement is a central element of learning during childhood and contributes to the integral strengthening of cognitive, psychomotor and social skills and abilities. The qualitative approach used for the selection of the instruments and analysis of the information collected, concludes that for the group of participants, body movement is infrequent as a resource for the mediation of mathematical skills. This suggests that the concept of memorization should be abandoned and instead the pedagogical mediation of the subject should be rethought from an open, dynamic, creative, effective and quality curriculum. The innovative pedagogical approach must respond to the principles of a transformative education, that from the body movement (understood as the natural abilities to jump, turn, walk, run, maintain balance, coordination and the ability to concentrate), make each student the protagonist of their individual learning, allowing physical, emotional and cognitive unification.

ABSTRACT Games as recreational activities constitute an important element in the development of the pedagogical process of Physical Education; tt contributes to collective work, formation of values such as: courage, perseverance, discipline, honesty, camaraderie, organization, respect for the rules, among others, which makes it contain great biological psychological and pedagogical value evidenced in its activities and in the benefits it brings to human beings. However, despite this approach being a strength in the Cuban educational system, the pre-sports game is not promoted from a scientific and academic point of view to achieve these aforementioned components. That is why the objective was projected to characterize the pre-sports games implemented by the teachers of the Physical Education department in the first two years of professional training at the Universidad de Oriente, Cuba. As empirical methods, an interview with teachers and an observation guide dedicated to the teaching-learning process in Physical Education are applied. An attempt is made to know the potential and weaknesses that pre-sports games have to improve the physical and sports skills of these students, in addition to the values in which comprehensive training can be contributed from these practices. The insertion of this type of games has had a very positive level of opinion from students and teachers.

RESUMEN Los juegos como actividades lúdicas constituyen un elemento importante en el desarrollo del proceso pedagógico de la Educación Física; se contribuye al trabajo en colectivo, formación de valores como: la valentía, la perseverancia, la disciplina, la honestidad, el compañerismo, la organización, el respeto a las reglas, entre otros, lo cual hace que contenga un gran valor biológico, psicológico, pedagógico, evidenciados en sus actividades y en los beneficios que reporta al ser humano. No obstante, a pesar de ser este planteamiento una fortaleza en el sistema educativo de Cuba, no se potencia desde el punto de vista científico y académico el juego pre deportivo para lograr estos componentes antes mencionados. Es por ello que se proyectó como objetivo caracterizar los juegos pre deportivos que implementan los profesores del departamento de Educación Física en los dos primeros años de la formación de profesionales en la Universidad de Oriente, Cuba. Como métodos empíricos se aplica una entrevista a los profesores y una guía de observación dedicada al proceso de enseñanza aprendizaje en la Educación Física. Se intenta conocer las potencialidades y debilidades que poseen los juegos pre deportivos para mejorar las habilidades físicas y deportivas de estos estudiantes, además de los valores en los que se pueden tributar a la formación integral desde estas prácticas. La inserción de este tipo de juegos ha contado con un nivel de opinión muy positivo por parte de los educandos y los profesores.

Learning design at tertiary level is a challenging and complex task with many aspects to take into consideration (Bennett, Lockyer, Agostinho 2018; Bower and Vlachopoulos 2018, 975; Bates, 2019). Learning design is identified as a core aspect of a tertiary educator's role, but often, little guidance is given to educators on this topic. Changes in the higher education landscape also bring about questions about ideal learning design. With changing times that require institutions to introduce other models like blended and online learning, more pedagogical guidance might be necessary to advise lecturers on best practices in terms of module design (Kebritchi, Lipschuetz, and Santiague 2017). To aid learning design thinking and to make the pedagogic structure of the design apparent, Laurillard and Ljubojevic (2011) and others have suggested the use of a learning design tool or aid. A learning design tool is a means which can provide analytical support for lecturers to evaluate their own practices (Bower et al. 2011). This study looks at the creation of a customised learning design tool (CLDT) and discusses whether it can serve as an Electronic Performance Support System, which is a tool that can guide and assist users in their roles in the workplace. This case study canvassed the experiences and opinions of faculty members in Military Education on the use of this CLDT. The tool is designed to capture and depict various features of a module's design. This study made use of design-based research which is a methodology requiring a phased approach and aims to influence practice. Inputs from the participants revealed the perceived value and benefits along with the necessary amendments needed for the tool.

Resumen: Se diseña y simula una antena de registro periódico fractal para un radar de penetración terrestre (GPR) con el fin de evaluar la detección de minas plásticas. El concepto de pseudo-ángulo de Brewster se considera en la simulación para forzar el componente de reflexión a un valor mínimo. La metodología se enfoca en la caracterización y modelado de los medios de transmisión y la mina plástica, además, se simula la presencia de la onda estacionaria en el sistema para evaluar la señal de retorno en la antena receptora del GPR. Como resultado se destaca la característica multibanda de la antena fractal log-periódica y la relación señal a ruido (SNR) de 10,17 dB obtenida para la frecuencia de resonancia de 1,35 GHz. Asimismo, el pseudoángulo de Brewster de 70,47° minimiza la reflexión de la onda electromagnética incidente en la transición entre dos medios dieléctricos, con pérdidas y dispersivos en frecuencia (espacio libre-tierra).

Abstract: A fractal log periodic antenna for a Ground Penetrating Radar (GPR) is designed and simulated to evaluate the detection of plastic mines. The Brewster pseudo-angle concept is considered in the simulation to force the reflection component to a minimum value. The methodology focuses on the characterization and modeling of the transmission media and the plastic mine, in addition, the presence of the standing wave in the system is simulated to evaluate the return signal in the receiving antenna of the GPR. As a result, the multiband characteristic of the log-periodic fractal antenna and the signal-to-noise ratio (SNR) of 10,17 dB obtained for the resonance frequency of 1,35 GHz stand out. Likewise, the pseudo-Brewster angle of 70,47° minimizes the reflection of the incident electromagnetic wave in the transition between two dielectric media, with losses and dispersive in frequency (free space-ground).

Abstract Background: Magnetic Resonance Imaging (MRI) of the prostate is a key diagnostic tool for identifying prostate carcinoma. The Prostate Imaging-Reporting and Data System (PI-RADS) scale is the standard system for interpreting these images. Standardizing and evaluating this scale is crucial for ensuring consistent and reproducible results. Objective: This study aims to assess both the interobserver and intraobserver agreement of the PI-RADS version 2.1. Material and methods: In this retrospective observational study, 129 prostate MRI scans from patients with suspected prostate cancer were evaluated. Three radiologists, each with different levels of experience, analyzed these scans at two separate times using the PI-RADS 2.1 scoring system. Both intraobserver and interobserver agreements were measured. Results: The study found substantial interobserver agreement (kappa > 0.6) across all categories, with category 5 showing the highest level of agreement. Intraobserver reproducibility was also high, with the highest kappa value reaching 0.856. Further analysis based on the radiologists’ years of experience revealed significant interobserver agreement in all instances. Conclusions: The PI-RADS 2.1 classification system demonstrates high reproducibility across different categories, particularly for lesions more likely to be clinically significant cancers. This underscores its reliability in varied diagnostic scenarios.

Resumen Antecedentes: La resonancia magnética (RM) de próstata es uno de los métodos diagnósticos para la identificación del carcinoma de próstata. La escala PI-RADS (Prostate Imaging and Reporting Data System) es el sistema usado para la interpretación de estas imágenes. Es importante, para su reproducibilidad, la estandarización y la evaluación de dicha escala. Objetivo: Determinar la concordancia inter- e intraobservador de la versión 2.1 del PI-RADS. Material y métodos: Estudio observacional retrospectivo, evaluando 129 RM de pacientes con sospecha de cáncer de próstata por tres radiólogos con diferentes años de experiencia y en dos momentos del tiempo, usando el puntaje PI-RADS 2.1. Se evaluó la concordancia intra- e interobservador. Resultados: La concordancia interobservador fue sustancial (kappa > 0,6) en todos los observadores, siendo la categoría 5 la de mayor acuerdo interobservador. Se observó una alta reproducibilidad intraobservardor, con la mayor kappa siendo de 0,856. Cuando se realizó el análisis según años de experiencia de los radiólogos, la concordancia interobservador fue significativa en todos los casos. Conclusiones: El sistema de clasificación PI-RADS 2.1 es reproducible para las diferentes categorías y aumenta la concordancia cuando se trata de lesiones con mayor probabilidad de cáncer clínicamente significativo.

Education systems are shaped by various internal and external contextual forces (De Beer, 2017). External contextual trends typically include language, demography, geography, technology, politics, and financial and economic trends. Religion represents one of these external contextual trends that can affect an education system (see Van der Walt, Potgieter & Wolhuter, 2010; Wolhuter & Van der Walt, 2018). Making use of established metabletic-comparative methodology, this article seeks to highlight the impact of religion as a formative factor of education in the BRICS countries. Religion is treated significantly differently in the education systems of the BRICS member states. In schools in India and China, no religious activities are allowed in accordance with the respective constitutions, while any religious activities may take place in schools in Brazil, Russia and South Africa, provided that the activities comply with particular guidelines. Broadly considered, any religious activities are conducted in primary schools in Brazil, provided that attendance is voluntary. Religion in Brazilian schools is influenced by the strong position of the Roman Catholic faith in Brazilian society, which could potentially be detrimental to minority groups in Brazil (Senefonte, 2018:440). Learners in Russia, according to Russian law, are free to choose for themselves the religious module in which they wish to receive education. Schools in Russia do not, however, always implement this legislation correctly, since a school's resources actually determine which module the learners should take. The manner in which religion is being dealt with, causes unhappiness among learners and parents as they do not really have freedom of choice regarding the religious module in which they wish to receive instruction (Zöllner, 2016). The legislation in China clearly states that no religious activities may take place in public schools, yet the ruling party of China intends to enshrine tenets of atheism in learners in schools (Vickers, 2022; Wang & Froese, 2020). Compared to the other BRICS member states, China has the most officially, constitutionally recognised ethnic groups. In terms of legislation and policy formulations, the ethnic minority groups obtain various benefits in terms of education. The wide variety of ethnic groupings poses various challenges to the government of China as the views of all these groups in the education system have to be taken into account. Various documents, including the South African Schools Act 76 of 1996, and other education policies provide clear guidelines as to how religion ought to be dealt with in South African schools. In South Africa, learners are taught various major deities worldwide. All learners in South Africa are exposed to the concept of religion through the subject Life Orientation (Grades 7-12). Teachers in South Africaface the challenge of respecting all kinds of religions and not preaching their own views on a religion. This challenge of respecting all religions can result in conflict in schools, as learners may feel that they will be discriminated against if one type of religion is singled out, for example during assembly. This underscores the role and value of South African teachers in inculcating citizenship values (see Wolhuter, Janmaat, Van der Walt & Potgieter, 2020). The Government of India faces opposition from minority groups with regard to religion in schools as the socio-political hegemony religion is especially preferred in terms of the drafting of academic textbooks (Traub, 2018). This preferential treatment of a particular religion is contrary to the Indian constitution, as no single religion may be singled out, nor should any religion be discriminated against (Majumdar, 2018). The preference given to a particular religion in textbooks can result in a negative impact on the education system of India. The analysis and interpretation show that there is still a close relationship between religion and education in the BRICS countries. However, all five BRICS member states face different problems regarding religion and each of the five member states also deals with its problems differently. This conclusion is now unpacked in this summary, and in detail defended in the ensuing full text. In terms of dealing with religion, South Africa appears to be more tolerant than Brazil, Russia, India and China, although this tolerance still causes more problems for the South African government, in the sense of opposition from various adherents of a wide variety of faith groupings who would like schools to play a role in strengthening the religious beliefs of their children. Several court cases have been fought in South Africa as schools struggle to accommodate the wishes of all religious groups in South Africa (see Nthontho, 2020). In contrast to forces in all the BRICS countries trying to separate religion and (public) education, the United Nations Declaration of Human Rights, the proto-charter of Human Rights Charters in the contemporary world, Article 26 states that everyone has the right to education, education should be oriented towards the total development of the child's personality, and that parents have a preferential right to decide on the type of education their children should receive. The BRICS member states can learn from each other how to deal with religion in schools, even though none have yet managed to deal satisfactorily with religion in education. The common factor among all five BRICS countries is that religion is used again and again (consciously or unconsciously) to reinforce political or ideological hegemony. It seems that the shortcoming in all these countries is pointing to a lack of recognition of the place and role of religion in the lives of their citizens and that secular-political objectives, notably the forcing of official ideological hegemony, as well as the achievement of national unity above the full recognition of religious freedom, are also stated in the education system and in citizens 'choice of the kind of religious education of their children. As a result, the role of religion in creating a strong moral fibre for a society therefore never seems to come into its own. Moreover, judging by the United Nations Charter's Human Rights provisions on education, educative education (incl. teaching and learning), in accordance with its full scope of semantic value, does not currently come into its own. The same seems to be the case as regards the human right to parental advocacy with respect to religious education. The experience of the BRICS countries in terms of religion-in-education shows that it is sensible and even necessary, for example, along the path of enlarged parental speech in education and school autonomy, to allow more room for religious freedom in education. The BRICS countries are currently being proposed as the leading grouping of the Global South in a new formative world order. Against this background, current trends regarding religion-in-education in these countries therefore probably represent a bold example. However, it should nonetheless be denounced by the academic community and better examples should subsequently be extracted and presented from other national education systems from future research.

'n Onderwysstelsel word deur verskeie samelewingskontekstuele kragte gevorm. Hierdie kontekstuele faktore sluit taal, demografie, geografie, tegnologie, politiek en finansiële en ekonomiese tendense in. Godsdiens is een van die laasgenoemde tendense wat 'n onderwys-stelsel kan beïnvloed. Die BRICS-organisasie bestaan uit Brasilië, Rusland, Indië, Sjina en Suid-Afrika en is 'n supra-nasionale blok wat baie aandag in die openbare sowel as akademiese diskoers oor internasionale politiek en maatskaplike kwessies trek (De Beer, 2017). Godsdiens word wyd geag as 'n omstrede en sensitiewe faktor in onderwysstelsels (sien Van der Walt, Potgieter & Wolhuter, 2010). In hierdie artikel word godsdiens as vormgewende faktor van die onderwysstelsels in die BRICS-lande ondersoek, om die waarde daarvan as 'n aanskouingsles vir Suid-Afrika en ander lande te bepaal. Die BRICS-lidlande is doelbewus vir hierdie navorsing gekies weens die besondere waarde van hierdie lande as vertoonvenster van onderwysstelsels se antwoord op samelewingstendense van die een-en-twintigste eeu. Dokumentontleding is uitgevoer ten opsigte van beleidsdokumente, wetgewing, artikels en staatspublikasies, ten einde inligting in te samel. In die verwerking en interpretasie van inligting is die metableties-vergelykende metode gebruik ten einde beste praktyke ten opsigte van die hantering van godsdiens in die onderwysstelsels vanuit die BRICS-lidlande te identifiseer. Die ondersoek het ernstige tekortkominge in al die BRICS-lande se hantering van godsdiens in onderwys aan die lig gebring. Nie een van die lande se beleid of praktyk slaag die toets, soos gemeet aan die Verenigde Nasies se Handves van Menseregte nie. Die noodsaak van voortgesette navorsing oor die plek van godsdiens in die onderwysstelsels van die wêreld word ten slotte verduidelik.

Resumen La determinación del valor de los ahorros fiscales y el impacto del impuesto a la renta en la valuación de empresa depende del sistema tributario vigente en el mercado. Los efectos fiscales que implican pagos y ahorros deben analizarse con el sistema tributario donde opera la firma. Los trabajos de Modigliani y Miller (1963) y Miller (1977) suponen un sistema clásico de imposición a la renta. La Organización Mundial del Comercio (OCDE) identifica siete sistemas tributarios clasificados en dos grandes grupos: integrados y clásicos. El trabajo revisa los modelos existentes, particularmente el Modelo General. Seguidamente, expone las ecuaciones de valor correspondientes a los diferentes sistemas tributarios. Mediante un análisis de casos se analiza el impacto en las variables del sistema tributario en el que opera la firma, según los sistemas clasificados por la OCDE.

Abstract The determination of the tax savings´ value and the impact of income tax on the firm valuation is related to the current tax systems. The tax effects imply cash out flow and savings, and, must be analyzed with the tax systems where the firm operates. Modigliani and Miller (1963) and Miller (1977) works suppose a classical system of income tax. The World Trade Organization (OCDE), identify seven tax systems classified into two large groups: integrated and classical. The paper reviews the existing models, particularly the General Model. Next, shows the value equations corresponding to the different tax systems. Through an analysis of cases, the impact on the variables of the tax system in which the firm operates is analyzed, according to the systems classified by the OECD.

Objective: This study aimed to research the factors that cause school dropout and whether technology can positively influence the reduction of this phenomenon in adolescents between 11 and 17 years old. Method: The research was conducted under a qualitative-exploratory approach, according to Hurtado (2010) through an in-depth interview based on Hernández-Sampieri et al. (2017). The sample was 92 students, from two schools located in two different regions in Costa Rica for the year 2021. Results: The gender distribution and the dropout rate in the selected sample indicate that the male gender has the highest dropout rate with 65.22%, some studies can corroborate like Santodomingo (April 19, 2021), the main reasons for this result are the abundance of unskilled jobs for men and the value system associated with the male gender. Findings: The female gender has a higher level of dropout in rural areas (53.12%), and one important reason is teenage pregnancy. Conclusions: Students who drop out of the school system do so mainly for reasons associated with a lack of interest in classes and economic problems in the family environment. Finally, it is concluded that for a virtual education process to be successful, it is not only enough to use technology as a tool, the teacher must establish a teaching model that is agile, flexible, and dynamic to maintain the student's interest. Among the recommendations, measures are proposed to reduce school dropout rates in the institutions.

Objetivo: Este estudio tuvo como objetivo investigar los factores que causan el abandono escolar y si la tecnología puede influir positivamente en la reducción de este fenómeno en adolescentes entre 11 y 17 años. Método: La investigación se realizó bajo un enfoque cualitativo-exploratorio, según Hurtado (2010) a través de una entrevista en profundidad basada en Hernández-Sampieri et al. (2017). La muestra fue de 92 estudiantes, de dos colegios ubicados en dos regiones diferentes de Costa Rica para el año 2021. Resultados: La distribución por género y la tasa de deserción en la muestra seleccionada indican que el género masculino tiene la mayor tasa de deserción con un 65,22%, algunos estudios lo pueden corroborar como Santodomingo (April 19, 2021), las principales razones de este resultado son la abundancia de trabajos no calificados para los hombres y el sistema de valores asociado al género masculino. Conclusiones: El género femenino tiene un mayor nivel de deserción en el área rural (53,12%), y una razón importante es el embarazo adolescente. Conclusiones: Los estudiantes que abandonan el sistema escolar lo hacen principalmente por razones asociadas a la falta de interés en las clases y problemas económicos en el entorno familiar. Finalmente, se concluye que para que un proceso de educación virtual sea exitoso, no sólo basta con utilizar la tecnología como herramienta, el docente debe establecer un modelo de enseñanza ágil, flexible y dinámico para mantener el interés del alumno. Entre las recomendaciones, se proponen medidas para reducir el abandono escolar en las instituciones.

Objetivo: Este estudo teve como objetivo investigar os fatores que causam a evasão escolar e se a tecnologia pode influenciar positivamente a redução desse fenômeno em adolescentes entre 11 e 17 anos. Método: a pesquisa foi realizada sob uma abordagem qualitativa-exploratória, conforme Hurtado (2010) por meio de uma entrevista em profundidade baseada em Hernández-Sampieri et al. (2017). A amostra foi composta por 92 alunos, de duas escolas localizadas em duas regiões diferentes da Costa Rica, para o ano de 2021. Resultados: a distribuição de gênero e a taxa de evasão na amostra selecionada indicam que o gênero masculino tem a maior taxa de evasão com 65,22%, alguns estudos podem corroborar isso como Santodomingo (April 19, 2021), as principais razões para esse resultado são a abundância de empregos não qualificados para homens e o sistema de valores associado ao gênero masculino. Conclusões: O gênero feminino tem um nível mais alto de abandono escolar na área rural (53,12%), e um motivo importante é a gravidez na adolescência. Conclusões: Os alunos que abandonam o sistema escolar o fazem principalmente por motivos associados à falta de interesse nas aulas e a problemas econômicos no ambiente familiar. Por fim, conclui-se que, para que um processo de educação virtual seja bem-sucedido, não basta usar a tecnologia como ferramenta; o professor deve estabelecer um modelo de ensino ágil, flexível e dinâmico para manter o interesse do aluno. Entre as recomendações, são propostas medidas para reduzir o abandono escolar precoce nas instituições.

The Americas contain highly biodiverse yet vulnerable ecosystems, with many threatened species inadequately protected. Finer-scale, localized habitat assessments are crucial for effective conservation planning, but continental-scale high-resolution vegetation maps remain limited. This study addresses this gap by identifying critical vegetation types across the Americas using the standardized framework of the International Vegetation Classification (IVC) system at the macrogroup level, representing the finest vegetation classification available across the region, as well as the highest-resolution Area of Habitat (AOH) maps currently available. By combining these high-resolution IVC macrogroup maps with detailed AOH maps, we highlight at-risk vegetation types based on 1) threatened and macrogroup-associated species (species that have at least 50% of their AOH in one macrogroup), 2) current protection levels, and 3) projected threats from land use changes, and 4) develop a conservation value index (CVI) that accounts for all these factors. The results highlighted the remarkable diversity of high conservation value macrogroups across the Americas, emphasizing their significance in regions such as the Andes, montane Mesoamerica, the Caribbean, Brazil's Cerrado, and the Atlantic Forest. Among the highest-scoring macrogroups, the Northern Andean Montane & Upper Montane Humid Forest emerged as critically important, harboring a high number of threatened and macrogroup-associated species. Other macrogroups of immediate conservation concern include the Brazilian Atlantic Montane Humid Forest, Pacific Mesoamerican Seasonal Dry Forest, Caribbean Lowland Humid Forest, and Central Midwest Oak Forest, Woodland and Savanna. However, the study revealed that nearly three-quarters of the over 300 macrogroups in the Americas fall below the global target of 30% protection. Notably, a fifth of all species were macrogroup-associated species, including over 40% of threatened species. Our findings emphasize the need for targeted conservation strategies that consider finer-scale habitat classifications and paired with high-quality species distribution data to guide conservation strategies for biodiversity across the Americas.

Las Américas contienen ecosistemas altamente biodiversos pero vulnerables, con muchas especies amenazadas insuficientemente protegidas. Las evaluaciones de hábitat hechas a escala más detallada son cruciales para una planificación eficaz de la conservación, pero los mapas de vegetación de alta resolución a escala continental siguen siendo limitados. Este estudio aborda esta brecha, identificando tipos de vegetación críticos en las Américas utilizando el marco estandarizado del sistema de Clasificación Internacional de Vegetación (IVC) a nivel de macrogrupo, que representa la clasificación de vegetación más detallada disponible en toda la región, así como los mapas de Área de Hábitat (AOH) de mayor resolución disponibles en la actualidad Al combinar estos mapas de IVC de alta resolución con mapas de AOH, determinamos los tipos de vegetación en riesgo basados ​​en 1) especies amenazadas y asociadas a macrogrupos (especies que tienen al menos el 50% de su AOH en un macrogrupo), 2) niveles de protección de las especies, y 3) amenazas proyectadas por cambios en el uso del suelo , y 4) desarrollar un índice de valor de conservación (CVI) que tenga en cuenta los tres factores anteriores. Los resultados demuestran la notable diversidad de macrogrupos de alto valor de conservación en las Américas, enfatizando su importancia en regiones como los Andes, la Mesoamérica montañosa, el Caribe, el Cerrado de Brasil y el Bosque Atlántico. Entre los macrogrupos con mayor puntuación, el Bosque Húmedo Montano Norte Andino y Alto Montano emergieron como de importancia crítica, ya que albergan un gran número de especies amenazadas y asociadas a macrogrupos. Otros macrogrupos de interés para la conservación incluyen el Bosque Húmedo Montano Atlántico de Brasil, el Bosque Seco Estacional Mesoamericano del Pacífico, el Bosque Húmedo de Tierras Bajas del Caribe y el Bosque de Robles, Bosques y Sabanas del Medio Oeste Central. Sin embargo, el estudio reveló que casi tres cuartas partes de los más de 300 macrogrupos en las Américas se encuentran por debajo del objetivo global del 30% de protección. En particular, una quinta parte de todas las especies estaban asociadas a un único   macrogrupo, incluidas más del 40% de especies amenazadas. Nuestros hallazgos enfatizan la necesidad de estrategias de conservación específicas que consideren clasificaciones de hábitats a escala detallada y se combinen con datos de distribución de especies de alta resolución para guiar las estrategias de conservación de la biodiversidad en las Américas.

As Américas abrigam ecossistemas altamente biodiversos, porém vulneráveis, com muitas espécies ameaçadas insuficientemente protegidas. Avaliações de habitat em escalas mais detalhadas são cruciais para um planejamento eficaz de conservação, mas mapas de vegetação de alta resolução em escala continental ainda são limitados. Este estudo aborda essa lacuna, identificando tipos críticos de vegetação nas Américas usando o quadro padronizado do sistema de Classificação Internacional de Vegetação (IVC) no nível de macrogrupo, que representa a classificação de vegetação mais detalhada disponível em toda a região, bem como os mapas de Área de Hábitat (AOH) de maior resolução disponíveis atualmente. Ao combinar esses mapas de IVC de alta resolução com mapas de AOH, determinamos os tipos de vegetação em risco com base em 1) espécies ameaçadas e associadas a macrogrupos (espécies que têm pelo menos 50% de sua AOH em um macrogrupo), 2) níveis de proteção das espécies, e 3) ameaças projetadas por mudanças no uso do solo, e 4) desenvolvemos um índice de valor de conservação (CVI) que leva em consideração os três fatores anteriores. Os resultados demonstram a notável diversidade de macrogrupos de alto valor de conservação nas Américas, enfatizando sua importância em regiões como os Andes, a Mesoamérica montanhosa, o Caribe, o Cerrado do Brasil e a Mata Atlântica. Entre os macrogrupos com maior pontuação, o Bosque Úmido Montano Norte Andino e Alto Montano emergiram como de importância crítica, abrigando um grande número de espécies ameaçadas e associadas a macrogrupos. Outros macrogrupos de interesse para a conservação incluem o Bosque Úmido Montano Atlântico do Brasil, o Bosque Seco Estacional Mesoamericano do Pacífico, o Bosque Úmido de Terras Baixas do Caribe e o Bosque de Carvalhos, Florestas e Savanas do Centro-Oeste Central. No entanto, o estudo revelou que quase três quartos dos mais de 300 macrogrupos nas Américas estão abaixo da meta global de 30% de proteção. Em particular, um quinto de todas as espécies estava associado a um único macrogrupo, incluindo mais de 40% das espécies ameaçadas. Nossas descobertas enfatizam a necessidade de estratégias de conservação específicas que considerem classificações de habitats em escala detalhada e se combinem com dados de distribuição de espécies de alta resolução para orientar as estratégias de conservação da biodiversidade nas Américas.

Abstract In the design of a High Complexity Visual Identity System, the use and application of a repertoire of secondary identifiers gives value to the identity itself. The application of two-dimensional frames applied to three-dimensional spaces effectively impacts the identity of the company, redefining the Visual System itself, turning the architectural space into a corporate signage milestone within the Three-Dimensional Program. Currently, recognized clothing brands resort to mastering two-dimensional space with the aim of becoming universal graphic symbols with high power of remembrance within an urban space.

Resumen En el diseño de un Sistema de Identidad Visual de Alta Complejidad, el uso y aplicación de un repertorio de identificadores secundarios otorga valor a la identidad misma. La aplicación de tramas bidimensionales aplicadas a espacios tridimensionales impacta eficazmente en la identidad de la empresa, resignificando el propio Sistema Visual convirtiendo al espacio arquitectónico en un hito señalético corporativo dentro del Programa Tridimensional. Actualmente, marcas de Indumentaria reconocidas, recurren al dominio del espacio bitridimensional con el objetivo de convertirse en símbolos gráficos universales de alto poder de recordación dentro de un espacio urbano.
