Published: June 2024

The products of oxidative destruction of asphaltenes of heavy Paleozoic oils from the Ashalcha and Nurlat oilfields differing in the age of host sediments have been studied. It is shown that oxidation of the asphaltenes of both oils by hydrogen peroxide in the presence of acetic acid results in the release of occluded compounds. The compounds identified in their composition include n-alkanes, steranes, hopanes and methyl esters of n-alkane acids. A peculiarity of the asphaltenes of Nurlat oil occurring in the Devonian sediments is the presence of n-alkenes in the composition of occluded compounds. The presence of occluded compounds in the structure of asphaltenes is confirmed by the results of X-ray diffraction analysis.

The objective of this research is to evaluate various polymeric materials that have the potential to serve as substitutes or supplements to heavy vehicle structures for radiation-intensive environments. The materials under investigation include Nylon 6 (PA-6, C6H11NO), polyethylene (PE, C2H4), polypropylene (PP, C3H6), polyvinyl chloride (PVC, C2H3Cl), and polymethylacrylate (PMMA, C5H8O2). This study's primary aim is to determine each material's effectiveness in shielding against radiation and reducing exposure to vehicle occupants. As a new approach, this research examines the impact of utilizing polymeric materials and the potential health hazards for young drivers of both sexes, such as developing solid cancers from radiation exposure. According to the study, PVC was the most efficient polymer with a Transmission Factor (TF) of 0.44, leading to a 56% decrease in the relative risk estimate for the maximum thickness evaluated (20 cm). On the other hand, PP was identified as the least efficient, with a TF of 0.65, resulting in a 35% reduction in the relative risk estimate for the same thickness. The study concludes that each polymer has varying degrees of attenuation and that combining their properties is essential to achieving the desired level of risk reduction.

The subject of the paper is the modes and parameters of operation of mineral processing waste storage facilities. Liquid waste storage facilities that accumulate processing products and mine water from several mining enterprises are considered, taking into account climatic factors of influence, technological limitations on the volume of waste. The analysis of the main results shows that environmental safety in the operation of waste storage facilities is based on two principles: to prevent waste overflow over the edges of the embankment dam and to provide a protective layer of liquid over the bottom, which is formed from particles of dusty and clay fractions. The purpose of the study is to scientifically substantiate the possible modes of operation of liquid waste storage of mineral raw materials processing and mining, as well as the creation of methods for calculating their maximum possible volumes entering the storage during the year, taking into account environmental safety. The study used the methodology of logistic systems, in the framework of which storage facilities are considered as a node of accumulation, and its model includes a system of equations describing the height of the water mirror and the bottom level depending on the volume of placers from the water volumes that entered and withdrawn from it during the period of operation, which is analyzed, taking into account the geometric features of the storage bowl. As a result, a mathematical model of liquid waste storage, which accumulates processing products and mine water from several mining enterprises, has been developed, taking into account climatic factors of influence, technological limitations on waste volumes. This model allows to determine the level of the free surface mirror in any month of the year, as well as to calculate changes in the current height of the free surface mirror in the storage for any period of time. On the basis of these formulas and ecological safety requirements at operation of artificial storages of wastes from processing of mineral raw materials the restrictions on volumes of wastes which enter the storage during a year, or during spring months have been received. The use of these restrictions allowed to determine and justify the rational values of capacities on salable concentrates of mining enterprises, duration of their downtime for a certain period of the year. Keywords: storage of mineral processing waste, height of the water mirror, environmental safety of operation.

The article presents the results of research on automated systems of control and monitoring of explosion safety of dust and gas mixture during coal grinding in ball drum mills (BDM). The problem of the gas-dynamic factor, which arises at the disintegration of coals of middle stage of metamorphism (gas coals) in the atmosphere of closed or limited space, for example in mine workings, chambers, furnace furnaces, etc., is considered. Earlier, when burning anthracite coals, such a problem did not arise, since anthracite does not have a gas component of hydrocarbons. Therefore, all automated control systems were developed from the condition of grinding quality and optimal loading of the BDM. The work aims to develop an automated system of control and monitoring of explosion safety of coal-gas mixture in ball drum mills in the process of grinding gas coals in preparation for combustion. It is established that the sizes of coal grinding fractions in the BDMs from 50 microns to 250 microns correspond to the sizes of supermelonites from 10 microns to 200 microns to particles that are formed during sudden coal and gas emissions in mines. Coal supermelonites are the main source of gas emission into the atmosphere of mine workings, as at their formation there is the disintegration of the supramolecular organization of coal macromolecule and generation of methane. Crushing of gas coals in the BDM inevitably leads to the formation of the explosive methane-coal mixture, which further enters the furnace of the boiler unit. As a result, a new functional scheme for automatic regulation and optimization of parameters of the BDM with a measuring and computing system for controlling the temperature of the gas medium, pressure drop, and a self-tuning microprocessor controller was developed. A technological scheme for installing control and measuring equipment has been developed for preparing coal for burning in a thermal power plant boiler unit. Explosion safety control in the technological cycle of preparing gas coals for burning is carried out constantly using methane and oxygen concentration sensors. The operability of the control system was confirmed on the industrial mill of the boiler unit BKZ-160-100PT TPP of "Kramatorskteploenergo" TPP. Keywords: ball drum mill, coal grinding, methane, explosion safety, control system.

“Deus, pátria, raça e família”: a relação entre sujeitos negros e valores conservadores no Brasil Republicano
Authors: Oliveira de Abreu Gabrielle
Published: June 2024

À primeira vista, a atuação de um grupo político formado por sujeitos autodeclarados negros e mobilizado a partir de valores conservadores pode causar estranheza. Isso ocorre porque, historicamente, as aglutinações políticas lideradas por homens e mulheres negros estiveram pautadas em práticas e discursos de caráter progressista e orientadas pelo objetivo comum de combate ao racismo em todas as suas formas de manifestação na sociedade brasileira. O racismo pode ser entendido, grosso modo, como um sistema complexo de discriminação e opressão baseadas em cor e raça que impõem obstáculos à população negra no que tange ao acesso ao rol de direitos fundamentais e, por conseguinte, à cidadania plena.
¿Malezas o arvenses? Una propuesta conceptual para su manejo agroecológico
Authors: Gómez-Gómez Robin
Published: June 2024

Introducción. La percepción de que las plantas nativas de campos agrícolas no aportan nada bueno a los sistemas productivos y deben ser eliminadas en su totalidad, ha provocado múltiples problemas agronómicos, ambientales y sociales en los agroecosistemas alrededor del mundo, tales como selección de plantas resistentes a herbicidas, contaminación de cuerpos de agua, pérdida de biodiversidad, aumento en las poblaciones de insectos plaga y afectación de la salud de trabajadores agrícolas debido al uso intensivo de herbicidas. Objetivo. Analizar el origen de las malezas en la agricultura, las características biológicas que las hacen perjudiciales para las actividades del hombre y sus funciones ecológicas en el agroecosistema, así como proponer la aplicación del concepto de biodiversidad funcional para el manejo agroecológico de la vegetación en campos agrícolas. Desarrollo. En este momento de cambio hacia una producción agrícola con un menor uso de plaguicidas, el manejo de las malezas sigue siendo un gran reto. Para lograr que el manejo integrado de malezas avance hacia estrategias agroecológicas que permitan una reducción del uso de herbicidas es necesario promover las interacciones bióticas benéficas que regulan de forma natural a las malezas. El estudio y aplicación de la biodiversidad funcional en los agroecosistemas surge entonces como una necesidad para manejar la vegetación de forma tal que se minimicen los efectos negativos de las malezas en los cultivos y se maximicen los servicios agroecosistémicos de las arvenses. Conclusión. La diferenciación entre malezas y arvenses como parte de un manejo agroecológico de los sistemas de cultivo permitiría mantener un balance positivo productividad-biodiversidad en los agroecosistemas.

Published: June 2024

The equine industry is an essential source of job and income worldwide. The use of artificial insemination (AI) with frozen semen is an opportunity to continue disseminating the Colombian Criollo horse. Seminal cryopreservation studies in Colombian Criollo horses are limited, and there is no previous knowledge in deleterious changes induced by the cryopreservation process on the chromatin integrity of the spermatic cells. The present study aimed to verify the effect of the modified-INRA 82 and Botucrio® extenders on sperm kinematics, chromatin integrity, and morphology of cryopreserved Colombian Criollo sperm. Five ejaculates of five stallions were obtained, split into two samples, and frozen with two different extenders (modified-INRA 82 and Botucrio) and cooling curves. After freezing, samples were analysed with the CASA system. Sperm morphology, chromatin integrity, hypoosmotic, and thermoresistance tests performed. Data were analysed by MANOVA (parametrical variables) and Kruskal Wallis (non-parametrical variables) with SAS Studio ® software. Statistically significant differences (P≤0.05) were found for the progressive motility (14 ± 5 and 27 ± 13), and chromatin integrity (64 ± 3 and 69 ± 5) for modified-INRA 82 and Botucrio, respectively. Botucrio samples presented higher total motility at 30, 60, 90, 120, and 150 min and progressive motility at 60, 90, 120 min in thermoresistance test than modified-INRA 82. Botucrio and modified-INRA 82, are capable to conserve semen equine effectively from Colombian Criollo horses. However, Botucrio permitted an improved kinematics and higher chromatin integrity than modified-INRA 82.
The Social Construction of the Myth of Paddy Goddess in Sundanese Culture
Authors: Djunatan Stephanus
Published: June 2024

This research aims to find a sociological understanding of the Mother Earth myth in the Sundanese tradition in West Java, Indonesia. Based on an intercultural approach in philosophy, researchers combine cross-disciplinary analysis, namely philosophy, sociology and anthropology. This combination of interdisciplinary studies complements methods of interpreting texts and contexts regarding cognitive understanding, especially the principles of reasoning about meaningful worldviews in everyday life. The results of this interpretation are principles of reasoning or logic called functional logic. This argument about the logic of function starts from two layers of interpretation of two elements in the culture of agrarian society. The first element is the mythology of the Paddy Goddess, and the second element is the mythical figure of the Paddy Goddess, which is the main symbol in the description of rice cultivation. These two elements contain an understanding of the paradoxical relationship between two aspects that combine with each other in the management and structuring of the agricultural world. These two aspects are found in parental culture: father and mother. This study presents the interpretation of the text and context of the mythology and symbols of the Paddy Goddess and the practice of rice cultivation. Interpretation of mythology, the symbol of Paddy Goddess and rice cultivation requires a synchronic approach and emic analysis to conclude the implied meaning, namely the principle of function as the core meaning implied in the mythology of Paddy Goddess and Rice cultivation. This interpretation shows that logic functions as the main principle of reasoning that combines various cultural elements into a logical and meaningful 'way of seeing' the life world, which influences Sundanese people consciously or not in experiencing their culture in a logical and meaningful way.

Modelling in action. Examining How Students Approach Modelling Real Life Situations. Three Case Studies. Model of the Movement of an Elevator
Authors: Rivas Eugenia Marmolejo
Published: June 2024

By means of three case studies, we will present two mathematical modelling activities that are suitable for students enrolled in senior high school and the first year of mathematics at university level. The activities have been designed to enrich the learning process and promote
the formation of vital modelling skills. In case studies one and two, students were given a function that modelled an elevator’s movement and were asked to evaluate and improve it. In the third case study, students were given an objective – model an elevator’s movement –
and general guidelines on how to approach the modelling of a real life situation. Results show that when students were given an initial model, their focus was on the given model and their solutions emulated the form of the initial model. When the students were given an objective and general
modelling guidelines, their emphasis was on the elevator’s movement and understanding its behaviour. Both approaches are valuable, and a teacher’s decision on which one to select depends largely on the course’s objectives and the teacher’s aims.
Using Small -Step Refinement for Algorithm Verification in Computer Science Education
Authors: Simić Danijela
Published: June 2024

Stepwise program refinement techniques can be used to simplify program verification. Programs are better understood since their main properties are clearly stated, and verification of rather complex algorithms is reduced to proving simple statements connecting successive program
specifications. Additionally, it is easy to analyse similar algorithms and to compare their properties within a single formalization. Usually, formal analysis is not done in the educational setting due to complexity of verification and a lack of tools and procedures to make comparison easy.
Verification of an algorithm should not only give a correctness proof, but also better understanding of an algorithm. If the verification is based on a small step program refinement, it can become simple enough to be demonstrated within the university-level computer science curriculum. In
this paper we demonstrate this and give a formal analysis of two well- known algorithms (Selection Sort and Heap Sort) using the proof assistant Isabelle/HOL and program refinement techniques.

Any means of public transportation (aircraft, ships, and buses) may carry potentially covid19 positive individuals thus, wastewater-based epidemiology (WBE) should be implemented to avoid further spread. The present study focused on tracing the presence of SARS-CoV-2 in wastewater from holding tanks of national and international route buses, as well as the drainage system at the bus station. Testing was performed by the RT-PCR protocol established by the United States Center for Disease Control and Prevention (CDC). SARS-CoV-2 was detected in 8.88% of the wastewater samples from buses and drainage systems (4 of 45). Positives samples were sequenced, and Delta and Omicron were among the variants most prevalent. Our results show that WBE provides a reliable and sensitive tool for spotting the possible presence of COVID-19-positive individuals arriving by bus to a city. Also, the WBE coupled with Whole Genome Sequencing (WGS) may serve as an early warning to trace and display preventative measures upon the introduction of variants of concern.

Abstract: A need exists to better understand the relationships between COVID-19, coping behaviors, physical activity and stress, and COVID-19’s impact on way of life. A cross-sectional study design was used to examine adult physical activity, hope, depression, anxiety, and coping status by gender during the COVID-19 pandemic, and to determine the impact of these variables on the coping process. The study also examined the effect of gender on the relation between physical activity and dependent variables. A global survey instrument was used in this study, including 1,400 Turkish adults. This study identified significant gender-based differences regarding physical activity, hope, depression, anxiety, and coping status of adults, although no significant gender-based difference was found regarding hope scores. Furthermore, physical activity directly influenced coping (β = 0.10), hope (β = 0.12), and anxiety (β = -0.08). Hope directly and positively influenced coping (β = 0.45) and directly and negatively influenced anxiety (β = -0.25) and depression (β = -0.28). Moreover, gender did not directly affect physical activity, but it was associated with decreased coping and increased depression and anxiety. Finally, gender had no effect on the relation between physical activity and hope, coping, depression, and anxiety (p > 0.01). These outcomes support the critical importance of physical activity and hope when coping with COVID-19 regardless of gender.

Metodologicamente, este trabalho realiza uma revisão de literatura, além de revisão bibliográfica em arquivos de imprensa, acrescidas de discussões críticas. Para tanto, a perspectiva teórica mobilizada é a discursivo-desconstrutiv(ist)a. Este artigo destaca a importância de trabalhar as heranças epistemológicas por nós legadas, particularmente no que tange aos Estudos da Tradução, especialmente à tradução audiovisual, e a necessidade de vislumbrar essa modalidade de tradução mais como prática sócio-histórica-discursiva de linguagem e menos como uma mera “ponte” de acessibilidade.
TRANSLATION, LITERATURE, AND LANGUAGE TEACHING: DO THESE THREE AREAS COMPLEMENT EACH OTHER?
Authors: Canarinos Ana Karla , Pereira Wagner Monteiro
Published: June 2024

Abstract This paper aims to propose a possible methodological path in practices with literary texts in foreign language classes. Firstly, the idea of interpreting the literary text and the role of literature in an increasingly technocratic society will be debated. Secondly, the teaching of literature in foreign language classes will gain prominence in this study, and the role of pedagogical translation, among other factors, will be highlighted in this process. Therefore, recommending the use of literary texts as a genre with which grammatical content can be worked is not the intention. On the contrary, strategies that contemplate the specificity of the literary text will be outlined and a methodological path in the 21st-century school context will be proposed.
POTÊNCIAS POÉTICAS: LEITURA E TRADUÇÃO DE POESIA EM AULAS DE LÍNGUAS ADICIONAIS
Authors: Alves Cláudia Tavares , Santi Elena
Published: June 2024

Resumo Buscando transpor recorrentes barreiras e receios que são postos quando se pensa a presença de textos literários e, em especial, de textos poéticos, em aulas de línguas adicionais, o presente artigo se propõe a refletir sobre quais seriam possíveis caminhos para se utilizar a poesia como uma potencialidade didática voltada ao ensino e à aprendizagem de línguas, mais especificamente da língua italiana. Nosso objetivo é, em primeiro lugar, investigar quais seriam algumas das particularidades do texto poético que poderiam estimular o contato com a língua em aprendizagem, favorecendo o desenvolvimento de competências não só linguísticas, mas também sociais, críticas e interculturais. Para tanto, espera-se explorar o texto poético como uma zona de prováveis desassossegos, desencontros, dissonâncias, mas também de estímulos à curiosidade, às reflexões críticas e aos múltiplos processos de significação possibilitados pela língua. Nesse sentido, abordaremos a leitura de poesia atrelada ainda à prática da tradução, entendendo-a como uma possibilidade pedagógica de aproximação e de interpretação imersiva de um texto poético, dando foco maior ao processo tradutório em si, mais do que a um resultado final. Por último, partindo de reflexões relacionadas ao poema “Una città come questa”, do poeta italiano Giovanni Raboni, espera-se elucidar com um exemplo concreto em que medida a prática da leitura e da tradução de poesia pode ser entendida como uma atividade que valoriza o confronto crítico e intercultural com a língua adicional, isto é, não apaziguando as dificuldades e os incômodos encontrados, mas sim se apropriando deles e os utilizando como potências para a aprendizagem.

Published: June 2024

ABSTRACT Introduction: Academic monitoring is used as a complementary tool for knowledge construction among higher education students. It works as a mechanism to aid and guide the students, as well as to develop the communication skills beyond the essential knowledge of the monitor. This study aims to report a monitoring experience using different teaching and evaluation strategies through active forms of learning, applying interdisciplinary theoretical and practical activities for medical students. Experience report: This experience report, developed in a public health curricular component of a medical undergraduate course at a federal public university in Rio Grande do Sul, Brazil, presents quantitative data and debates the knowledge acquired through the implementation of education project activities. Discussion: Four semesters were analyzed, comparing records obtained from online forms without identification of the respondents related to the participation of the theoretical and practical monitoring sessions, with a higher participation rate in practical activities (42.31% vs. 25.55%). The main motivations for students looking for monitoring meetings were identified, with explanation of a research simulation stage being the most requested one. Practical monitoring sessions received higher evaluations compared to theoretical ones, considering three aspects: activity importance, clarity and didactics of the monitor, and elucidation of doubts. It was observed a relevant variation in the time assigned to the meetings, with a more frequent duration session of 60 minutes for theoretical activities and 30 minutes for practical activities. The comparison of the proposed practical and theoretical activities implemented through active forms of learning in the monitoring project evidenced the knowledge addition for both students, monitor or monitored, in the teaching-learning process when they are actively engaged in their own education. Conclusion: From the monitor’s perspective, there was a strengthening of their own competencies related to scientific knowledge.

ABSTRACT Coffea canephora beans are used for various industrial purposes, among which the use as soluble coffees stands out for producing beverages in blends with Coffea arabica. Due to the increase in demand, EMBRAPA launched ten monoclonal C. canephora cultivars, named Amazonian Robustas, adapted to the growing conditions of the Brazilian Amazon. However, the chemical composition of the beans of these cultivars is still little known. The present study aimed to estimate genetic parameters for the evaluated characteristics and determine the levels of bioactive compounds and organic acids in ten C. canephora cultivars. The experiment was set in Manaus, Amazonas, consisting of plants from the cultivars BRS 1216, BRS 2299, BRS 2314, BRS 2336, BRS 2357, BRS 3137, BRS 3193, BRS3210, BRS 3213, and BRS 3220. The cultivars were characterized according to the profile of bioactive compounds and organic acids.

ABSTRACT Water sources in the Brazilian semi-arid region commonly contain high levels of dissolved salts in their composition, standing out as one of the abiotic stresses that limit the expansion of irrigated fruit growing, especially salt stress-sensitive crops such as sour passion fruit. Thus, the use of elicitors, such as proline, can be an effective alternative to mitigate salt stress in plants. In this context, the objective of this study was to evaluate the effects of foliar application of proline on chlorophyll fluorescence, growth, quality and tolerance of sour passion fruit irrigated with saline water during the seedling formation phase. The experiment was conducted from July to October 2022, under greenhouse conditions in Campina Grande, PB, Brazil, using a completely randomized design, in a 5 × 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and four concentrations of proline (0, 5, 10 and 15 mM), with four replicates and two plants per plot. Water salinity from 0.6 dS m-1 reduces the maximum fluorescence, variable fluorescence, quantum yield of photosystem II and growth of ‘BRS GA1’ sour passion fruit seedlings. Foliar application of proline at concentrations ranging from 6 to 8.05 mM increases the growth in plant height, stem diameter and leaf area of sour passion fruit seedlings. The sour passion fruit genotype ‘BRS GA1’ is sensitive to water salinity, with a salinity threshold level of 0.6 dS m-1 and a reduction per unit increase in electrical conductivity of 10.49%.

ABSTRACT Downy mildew is one of the main foliar diseases affecting melon plants during the rainy season in the Northeast region of Brazil. Silicon (Si) application has emerged as an alternative method for pathogen control, forming physical barriers and activating defense mechanisms in plants. The objective of this study was to reduce the severity of downy mildew in melon plants during the rainy season through foliar application of Si. The treatments consisted of five rates (0, 0.25, 0.5, 1, and 2 L ha-1) of potassium silicate (12% Si and 15% potassium) applied from May to July 2022, with four replications. Disease severity was assessed using rating scales, chlorophyll contents, and transient chlorophyll a fluorescence (OJIP). The rate of 2 L ha-1 resulted in the best results by delaying pathogen development in leaves with disease incidence. Disease severity decreased to 68.27% and chlorophyll a, b, and total increased by 8.21%, 13.86%, and 9.72%, respectively. Si application resulted in beneficial changes in the following OJIP test parameters: ABS/RC, TR0/RC, ET0/RC, ABS/CS0, and TR0/CS0. During periods of high rainfall intensity and mild temperatures, Si application to melon plants reduces downy mildew severity and protects chlorophylls, enhancing the absorption flux (ABS) and electron storage (TR0) and transport (ET0).

ABSTRACT The caterpillar Ascia monuste orseis (Godart) (Lepidoptera: Pieridae) stands out as one of the main defoliating pests of brassicas. To mitigate the damage and reduce the impact on human health and the environment that results from the persistent and indiscriminate use of chemical insecticides, it is crucial to consider the use of botanical insecticides as a fundamental alternative for pest control. The aim was therefore to investigate the stimulus-response of the hydroalcoholic crude extract of Ocimum campechianum and of its dichloromethane (DCM) fraction on A. monuste orseis. Leaf consumption (cm2) of caterpillars exposed to the extract, caterpillar mortality in 24 h, total caterpillar mortality, pupal mortality, pupal period duration, and morphological malformation in adults were evaluated. Feeding the caterpillars for eight days with cabbage impregnated with the crude extract and its DCM fraction resulted in decreased caterpillar feeding, increased larval mortality (90%), lengthening of the pupal period (two days), and an increase in adult deformation (50%). Therefore, the crude extract of O. campechianum and its DCM fraction have potential for use in the alternative control of A. monuste orseis.

Abstract This review aims to identify and describe interventions to promote an ethical climate in health institutions. Method: a scope review carried out on PubMed, Virtual Health Library, EBSCOhost, and Google Scholar from October to December 2022. Data were analyzed using numerical and thematic synthesis and included two quasi-experimental and one experimental studies. Physicians, nurses, and other team members participated in this review, which describes the carried out interventions and obtained results. The interventions included workshops, ethics rounds, and an early action protocol that lasted from two weeks to six months. This review found a difference in the ethical climate for all participants in one study, only for nurses in another study, and no significant differences in the last studies. Few studies implement and evaluate interventions to promote an ethical climate. More studies are needed to improve content, didactics, and assessment methods in different contexts with several professionals.

Resumen Esta revisión busca identificar y describir intervenciones para promover un clima ético en instituciones sanitarias. Se realizó una revisión de alcance en las bases de datos PubMed, Biblioteca Virtual en Salud, EBSCOhost y Google Scholar entre octubre y diciembre de 2022. Los datos se analizaron mediante síntesis numérica y temática. Se incluyeron tres estudios: dos cuasiexperimentales y uno experimental. Los participantes fueron médicos, enfermeros y otros miembros del equipo. Se describen las intervenciones y los resultados obtenidos. Las intervenciones fueron talleres, rondas de ética y protocolo de acción temprana, con una duración de dos semanas a seis meses. Un estudio reveló diferencia en el clima ético para todos los participantes; otro para solo los enfermeros; y un estudio no reportó diferencia. Pocos estudios evalúan intervenciones en esta materia. Se necesitan más estudios para mejorar los contenidos, la didáctica y los métodos de evaluación en diferentes contextos con distintos profesionales.

Published: June 2024

Resumen El derecho a una muerte digna es ampliamente ignorado por el ordenamiento jurídico brasileño. Esta invisibilidad del proceso de finitud y sus consecuencias son el objeto de este estudio, que tiene como objetivo realizar una encuesta exploratoria para identificar los puntos relevantes que deben desarrollarse para garantizar un proceso de finitud digno. Se analizaron 50 publicaciones a través de una encuesta online y física de obras publicadas hasta marzo de 2023. Los estudios analizados expresan preocupación por los dilemas éticos de la atención a seres humanos en finitud, pero no analizan las formas de protección a la finitud existentes ni cuáles son las áreas que aún necesitan regulación para hacer efectiva esta atención. Se espera que esta investigación contribuya a fortalecer la visión crítica de la finitud, considerando la protección actual de la finitud, los límites jurídicos del Estado y los posibles pasos futuros para avanzar en los estudios aplicados a la actualización práctica del sistema jurídico brasileño.
