RESUMO - As mudanças climáticas em que o planeta Terra tem passado desde o início da primeira revolução industrial (1750-1850), tem causado impactos significativos na população humana e na biodiversidade, de forma direta e indireta, alterando a vida das pessoas e como os ecossistemas interagem com os meios abióticos. Neste contexto, tomou-se como base uma bibliografia especializada em climatologia geográfica, projeções das mudanças climáticas, aportes teóricos da oceanografia física estuarina, costeira e arqueologia subaquática. A partir disso, o presente artigo compilou, as principais consequências que as mudanças no clima poderão causar a sítios arqueológicos de naufrágios, sendo aplicada uma análise das consequências para um sítio arqueológico localizado no município brasileiro de Paranaguá, no Paraná. Os resultados demonstraram que essas mudanças podem descaracterizar o contexto arqueológico, ocasionando perdas de informações essenciais, além de alterar sua estrutura física, química e biológica e, por último, causar a destruição por completo dos sítios arqueológicos que estejam localizados em praias e em ambientes submersos, sendo necessário propor medidas preventivas de gerenciamento e preservação.

ABSTRACT - Climate change that the planet Earth has undergone since the beginning of the first industrial revolution (1750-1850) has caused significant impacts on human populations and biodiversity, both directly and indirectly, altering people's lives and how ecosystems interact with abiotic environments. In this context, specialized bibliographies in geographical climatology, projections of climate change, theoretical contributions from estuarine, coastal physical oceanography, and underwater archaeology were used as a basis. From this, this article compiled the main consequences that climate change may cause to shipwreck archaeological sites, applying an analysis of the consequences to an archaeological site located in the Brazilian municipality of Paranaguá, in Paraná. The results demonstrated that these changes can alter the archaeological context, leading to losses of essential information, as well as altering its physical, chemical, and biological structure, and ultimately causing complete destruction of archaeological sites located on beaches and in submerged environments, necessitating the proposal of preventive management and preservation measures.

Published: July 2024

RESUMO - No dia 25 de janeiro de 2019, a barragem B1 da mina Córrego do Feijão colapsou, formou uma enxurrada com cerca de 12 milhões de metros cúbicos de rejeito, que contaminou o Rio Paraopeba, seus afluentes e causou a morte de 270 pessoas. Neste contexto, o objetivo deste estudo é avaliar os impactos ambientais negativos decorrentes da contaminação do Rio Paraopeba - MG. Foram analisados dados do Instituto Mineiro de Gestão das Águas sobre o monitoramento da qualidade das águas superficiais da Bacia do Rio Paraopeba, a partir de dados de nove estações de monitoramento, entre 2017 e 2022. Os resultados apontaram concentrações de alumínio, arsênio, chumbo, ferro, fósforo, manganês, selênio e zinco acima dos valores de referência estabelecidos pela Resolução CONAMA nº 357/2005 para corpos hídricos de Classe 2, ao longo de toda a Bacia Hidrográfica. A contaminação por arsênio, chumbo e selênio foram originadas pelo desastre de Brumadinho, já os altos teores de alumínio, ferro, fósforo e manganês já eram observados antes de 2019. A partir de 2021 todos os parâmetros apresentaram tendência de queda na região do alto curso da bacia e aumento dos teores no baixo curso, o que sugere a migração destes contaminantes pela bacia.

ABSTRACT - On 25 January 2019, the B1 dam at the Córrego do Feijão mine collapsed, resulting in a torrent of around 12 million cubic metres of tailings, which contaminated the Paraopeba River, and caused the deaths of 270 individuals. This study aims to investigate the impacts of the disaster on the UPGRH SF3 - Paraopeba River Basin and analyse the progression of inorganic element contamination within the Paraopeba River. The data were obtained from the monitoring of surface water quality in the Paraopeba River Basin, developed by the Minas Gerais Institute of Water Management, from nine monitoring stations, on a time interval from 2017 to 2022. The results revealed concentrations of aluminum, arsenic, lead, iron, phosphorus, manganese and selenium, above the reference values set by CONAMA Resolution 357/2005 for water bodies classified as Class 2, across the SF3 basin. Contamination of arsenic, lead and selenium has emerged as a consequence of the Brumadinho disaster, but high levels of aluminum, iron, phosphorus, and manganese had already been detected prior to 2019. From 2021, all the parameters discussed showed a decreasing trend in the upper reaches and an increasing trend in the lower reaches of the basin.

Published: July 2024

This study presents the use of terrestrial magnetometry method in the characterization of a metamorphic and chromium-mineralized ultramafic body in the São Sepé region (RS). Several serpentinite exposures were recognized in the study area, characterized by a very evident schistosity marked by amphiboles and micas. The most preserved rocks are gray to dark green in color, silky to the touch and with folds and variable fracturing. The chromite present in serpentinites is associated with magnetite, and occurs in the form of small lenses. 1677 reading lines were made perpendicular to the main direction of the meta-ultramafic body, with 25m spacing between measurement points. The magnetometric maps revealed high-intensity anomalies related to meta-ultramafic rocks. 1677 reading lines were made perpendicular to the main direction of the meta-ultramafic body, with 25m spacing between measurement points. The magnetometric maps revealed high-intensity anomalies related to meta-ultramafic rocks. The results revealed the existence of highly magnetic individualized lenses orientated according to NE / SW, related to regional deformation events, with remobilization and mineral reconcentration. The direct relationship between high magnetization and chromite/ferro-chromite concentrations allows relatively detailed mapping of potentially mineralized areas, revealing dimensions more significant than the limits of the meta-ultramafic sequence defined in the geological map. The results indicate that the analytical signal amplitude map is a highly recommended product for planning sampling actions and reserve quantification, improving classical geological mapping.

This study was conducted to determine whether the mock board examination performance can predict a candidate’s performance in the Licensure Examination for Certified Public Accountants (LECPA). It covered the Bachelor of Science in Accountancy (BSA) graduates from a higher education institution in Pagadian City, Zamboanga del Sur, Philippines, who took the mock board examination and were first-time LECPA takers from the October 2022 to May 2023 batches. Participants were directly included in the study. A simple linear regression analysis was utilized to determine whether a candidate’s performance on the mock board could predict their LECPA performance. The model summary revealed a value of .474, which is below .5. Therefore, the study concluded that the mock board examination can predict overall LECPA performance. This result implied that higher scores on the mock board examination correlate with a higher probability of passing the LECPA. Based on these findings, the learning institution should regularly improve the mock board examinations. Suggestions include aligning the difficulty level of the mock board with the LECPA and having the assessment conducted by a Certified Public Accountant (CPA) examiner other than the mock board lecturer.

CONSTRUCTION AND OPERATIONAL PROPERTIES OF CONCRETE ON MODIFIED BINDER
Authors: Zhilkibaeva A.M. ,   International Educational Corporation
Published: July 2024

The most important tasks of science in the field of construction: facilitating reinforced concrete structures, accelerating and reducing the cost of technological processes, in particular, abandoning heat treatment of products, increasing the durability of concrete can only be solved by giving special properties to binders. The way to solve this problem lies through the expansion of the range of complex mineral additives. Natural and man-made substances in a dispersed state, insoluble in water and characterized by grain size less than 0.16 mm, are used as mineral additives for binders and concretes. Despite the different effectiveness, mineral additives have a similar qualitative chemical composition (oxides of silicon, aluminum and others). The differences are in their mineralogical composition, the ratio of components and the degree of dispersion, which determine the predominant mechanism of their action in cement systems. Depending on the properties of the mineral additive, it is possible to obtain multicomponent binders for concretes with special properties: fast-hardening, high-strength, sulfate-resistant and others with significant savings in the cement component. The effectiveness of superplasticizers in dispersed systems can be increased due to a different procedure for their introduction or by combining them with finely ground mineral fillers of various chemical nature. The article presents the possibility of obtaining heavy concretes with specified construction and operational characteristics using a complex mineral additive, which includes waste from the tailings of the Balkhash mining and Processing plant and silica, as well as superplasticizers of various natures: MasterGlenium 305, Master Rheobuild 1000K and Master Air 200.

The article is devoted to the analysis of the effect of the addition of zeolites on the properties of adhesives used in the woodworking industry. Zeolites with adsorption and catalytic properties were used as modifiers of adhesive systems. This work contributes to the creation of environmentally friendly adhesives for the woodworking industry, reducing the impact on the environment. The aim of the study is to modify adhesive compositions with different concentrations of zeolite and to study their effect on technological parameters. The methods of synthesis of modified adhesives and methods of their testing are described. The results show that the introduction of zeolites into the composition of adhesives accelerates the gelatinization process due to the catalytic action of alkali metal oxides contained in aluminosilicates. This reduces the polycondensation time and allows you to maintain the performance of the CF-LT-15 glue for 89 hours, which corresponds to technological standards. However, an increase in the size and concentration of aluminosilicate particles increases the conditional viscosity of the adhesive from 52 to 95 seconds, which complicates its application to substrates. In this regard, it is recommended to limit the filler content to 8 mass parts. This article summarizes the results of the study and offers recommendations for the industrial use of modified adhesives. The results may be of interest to both the scientific community and the woodworking industry, which is striving to create more efficient and environmentally friendly adhesives.

One of the current scientific directions in hydraulic engineering is to give irrigation canals a hydraulically and statically stable cross-sectional shape in the form of the most advantageous parabolic profile. This approach allows maximizing the sediment transport capacity of the flow and significantly reducing the time and costs of construction and maintenance works, using optimization criteria for next-generation machinery and mechanisms. The significance of this research lies in developing a new concept for designing, constructing, and operating irrigation canals in hydraulic engineering systems with cross-sectional shapes that are both hydraulically and statically stable. These shapes aim to maximize sediment transport capacity, ensure ecological sustainability of natural-technical basin systems, and contribute to national food security. The objects of study are hydraulic engineering structures, specifically the inter-farm canals of irrigation systems within the Syr Darya river basin in the southern region of the Republic of Kazakhstan. For the study, methods were used including stability analysis of earth slopes using circular-cylindrical sliding surfaces, methods based on analogy between shear curves and slopes, and methods based on the theory of limit equilibrium. Calculations have demonstrated the advantages, including increased resistance to cross-section deformation, reduced earthwork volumes during irrigation canal construction and cleaning by 20-25%, decreased materials and work volume for possible lining by 13-18%, narrower canal top width and land acquisition zones by 11-17%, lower labor costs by 13-16%, reduced construction costs by 14-18%, and decreased specific adjusted costs by 15-18%.

In the article, the optimal composition of the arbolite mixture was determined using a preliminary mathematical method for the manufacture of wall panels. With the help of optimal compositions, wall panels were manufactured and its stress state under load was calculated. For the production of arbolite products, the advanced technology of pressed arbolite, manufactured by conveyor method, has been applied. Using the methods of mathematical planning of experiments, the optimal composition was determined – the ratio of rice husk and a multicomponent binder with high strength. A method for calculating the stress state of wall plates based on rice husk and its straw with an internal thermal insulation layer of class B1 arbolite has been developed. Formulas for determining the distribution of tangential stresses along the longitudinal axis of a wall panel along its thickness are obtained. Deviations of the wall plate under the action of an off-center longitudinal load are determined. An experimentally developed method for calculating wall plates has been tested and confirmed. Experimental data on the testing of wall panels based on rice husk and straw of natural size have shown sufficient reliability and adequacy. The water absorption of arbolite based on rice husk and multicomponent binder was 24%, and the thermal conductivity λ = 0.18-0.19 W/ (m·oC). The resulting arbolite has a frost resistance of 30-35 cycles.
TEORIA RETRIBUTIVA DA PENA EM KANT E SEU PARADIGMA ENTRE A AUTONOMIA E O CONTROLE SOCIAL
Authors: Ambrosio Gleiner Pedroso Ferreira
Published: July 2024

Uma das discussões de maior urgência na ordem social e política do penalismo ocidental reside no correto equilíbrio entre a aplicação da pena em seu aspecto punitivo e o necessário contraponto preventivo, relacionado à figura da ressocialização do apenado, com esta última ganhando enorme força no Direito Penal Contemporâneo sobretudo com a ascensão da ideia do Direito Penal como a ultima ratio. No entanto, apesar da Criminologia residir na melhor ferramenta para compreender tal fenômeno na óptica da ciência criminal, a Teoria Retributiva da Pena de Immanuel Kant representou uma das mais destacadas perspectivas sociológicas acerca do tema, que se viabilizou por meio da defesa da forte coerção estatal como forma de garantir um bem até hoje muito caro à democracia contemporânea: a autonomia de vontade. Neste sentido, o presente artigo analisará a teoria penal de Kant, apresentando seus principais fundamentos, como a filosofia contratualista legitimou tal mentalidade e em que medida o Estado deve agir para garantir a autonomia dos indivíduos, ou seja, como e em que medida a retribuição é uma opção necessária para o filósofo, além de traçar comentários críticos na defesa da necessária adoção de um sistema penal misto.

Published: July 2024

Background: Masks, devices used to cover the face, nose, and mouth area to prevent the transmission of viruses, bacteria, diseases, and air pollution, have become a topic of pros and cons among the public regarding their impact on cardiorespiratory fitness during physical activity, as some claim that masks decrease airflow to the lungs thus reducing oxygen in the blood and muscles which makes activity more difficult, while other studies have shown no difference in cardiorespiratory fitness values with or without masks. The purpose of this study was to determine the difference in cardiorespiratory fitness levels when wearing a mask and not wearing a mask in physiotherapy students.
Methods: This study used an analytical observational design with a one-group pre-post test design and a consecutive sampling technique involving 35 physiotherapy students from the Faculty of Medicine, Universitas Udayana. This research was conducted at the Physiotherapy Building, Faculty of Medicine, Universitas Udayana, in June 2023. The inclusion criteria included physiotherapy students aged ≥ 18 with normal vital signs who used a 3-ply surgical mask. The exclusion criteria were students with a history of respiratory problems and those who did not use a 3-ply surgical mask. Cardiorespiratory fitness was measured using the Harvard step test.
Results: This study showed that the research subjects were dominated by students with poor cardiorespiratory fitness when wearing a mask or not wearing a mask, namely 35 students (100%).
Conclusion: There was no significant difference in cardiorespiratory fitness levels between mask wearers and non-wearers, with a p-value of 0.180 (>0.05).

Hypotheses were tested using PLS-based structural equation modeling using Smart-PLS software.
Results. The relevance of the TPB model is confirmed with modifications in the present study in Indian context. Attitude towards organic prosumption, and perceived behaviour control together accounted for 35.7 % of variation in the organic prosumption intention, and subjective norms had no effect on intention of organic prosumers. Organic prosumption intention explained 48.1 % variation in organic prosumption behaviour. Ease of practicing organic prosumption significantly moderated all cause effect relations predicting intention and behaviour. In the context of increasing awareness on the benefits of organic farming and prosumption behaviour, the study provides a theoretical explanation for explaining why people engage in organic prosumption behaviour.
Originality / scientific novelty. This paper examines the Theory of planned behaviour in the context of organic prosumption behaviour in agriculture. No literature exists in Indian context to explain such behaviour. Moreover, the perception of these farmers on the ease of practising organic prosumption is also examined as a moderator. Development of a theoretical model to explain organic prosumption behaviour in an Indian context is the novelty of the present study.
Practical value / implications. Organic farming and prosumption has gradually gain wide acceptance as a sustainable way of life. The United Nations have also highlighted the need for sustainable practices in production and consumption. Thus, in the immediate future, governments across the globe will have to look into policy formulations in organic farming and prosumption practices. This paper can contribute towards such efforts by throwing light into how prosumption behaviour is formed, and what are the factors that contribute to and moderate such behaviour.
Impact of the total expenditure shocks on food security: VAR model

Purpose. This study examines the causal relationship between total expenditures and food availability and identifies their shocks in food availability in Saudi Arabia.
Methodology / approach. The study uses a multivariate modeling technique of the Vector Autoregression (VAR) and its environment, the Granger Causality Test, Forecast Error Variance Decomposition (FEVD), and Impulse Response Function (IRF) for the observation period of 2000–2020 in Saudi Arabia.
Results. The results of the Granger causality show that investment expenditure has a significant impact on food availability in Saudi Arabia. However, consumption and government expenditures do affect food availability in Saudi Arabia, but have an indirect effect. The Impulse Response Functions show that the shocks of the selected variables require a long period to reach the long-run equilibrium level and the greatest response of the food availability variable is explained by its own shock and investment expenditure shocks.
Originality / scientific novelty. The novelty of this study is related to the investigation of a new model and focus on a new perspective. While traditional food security research has mostly concentrated on agricultural production, availability, and accessibility of food, as well as nutrition and health outcomes factors, this research conveys a new dimension by highlighting the link between total expenditure and food security. Their contribution expands the scope of food security research and highlights the impact of recognising the role of total expenditure in implementing and supporting food security at the household level.
Practical value / implications. It is important to design strategies and develop a budgeting plan to allocate a reasonable portion of total consumption and government expenditures on food items. Adding, regularly reviewing, and adapting the budgeting plan based on new challenges, and evolving priorities are essential to address the dynamic nature of food security.
Printemps qui commence ? De l’écopoétique à l’université
Authors: Cavallin Jean-Christophe
Published: July 2024

This text offers a collective reflection and feedback on five years of teaching in the Master écopoétique et création program at Aix-Marseille University. The duel of two highly whimsical pseudo-concepts – « Durassic Park » and « Descolatour Regime in literature » – serves to illustrate the double bind of a teaching and literary criticism inevitably torn between disciplinary solipsism and contextual urgency.
« L’animalité traverse l’humain de part en part ». Entretien avec Anne Simon

Zoopoetics studies the diversity of stylistic, linguistic and narrative means used to convey the diversity of animal emotions and behaviour, as well as the diversity of their worlds. How does this field of research fit in with environmental literary studies? How does zoopoetics help to renew the ways in which literature is studied, from school to university? Director of research at the CNRS, Anne Simon is a French researcher in literary and philosophical studies. A specialist in Proust, she has focused her work on the living and animality in literature, developing the field of zoopoetics research. Her publications include Une bête entre les lignes. Essai de zoopoétique (Marseille, Wildproject, 2021). She is in charge of the 'Animots' research programme, funded by the ANR between 2010 and 2014 and now supported by the République des savoirs unit (CNRS/ENS/Collège de France - PSL).
AVALIAÇÃO DO CONHECIMENTO SOBRE MEDICAMENTOS FITOTERÁPICOS EM ESTUDANTES DE GRADUAÇÃO DE UM CENTRO UNIVERSITÁRIO NO PARANÁ
Authors: Pabis Isabella Filipake , Lucca Patrícia Stadler Rosa
Published: July 2024

Este estudo explorou o conhecimento sobre medicamentos fitoterápicos em estudantes de graduação não relacionados à área da saúde em um centro universitário do Paraná. A crescente popularidade desses produtos e a falta de informações adequadas disponíveis para o público em geral justificam a investigação. Utilizando uma metodologia exploratória e descritiva de natureza quantitativa, foram entrevistados 105 acadêmicos de Administração, Engenharia Civil e Ciências Contábeis entre setembro e dezembro de 2023. Os resultados revelaram que 80% dos entrevistados conheciam medicamentos fitoterápicos como babosa, guaco, hortelã e espinheira-santa, mas 94,2% nunca haviam discutido o assunto em sala de aula, apesar de expressarem a crença na importância de incluir essa temática na graduação. Concluiu-se que há uma lacuna de conhecimento entre os estudantes universitários não ligados à saúde, evidenciando a necessidade de integrar informações sobre medicamentos fitoterápicos no currículo acadêmico para promover um uso mais informado e seguro desses produtos. Essa abordagem é crucial para prevenir possíveis consequências negativas decorrentes do uso inadequado desses medicamentos, contribuindo assim para a promoção da saúde e qualidade de vida dos estudantes e futuros profissionais.
MORTALIDADE INFANTIL EM MENORES DE CINCO ANOS NO PARANÁ: UMA ANÁLISE EPIDEMIOLÓGICA DA INFLUÊNCIA DA PROMOÇÃO À SAÚDE NA ATENÇÃO PRIMÁRIA
Authors: Grando Vitória Gabriela , Cavalli Luciana Osorio
Published: July 2024

Objetivos: Analisar epidemiologicamente a influência da redução das ações de promoção à saúde na atenção primária, influenciando na mortalidade infantil em menores de cinco anos no estado do Paraná, durante 2018-2022. Métodos: Este estudo, do tipo série temporal, utilizou dados secundários do Sistema de Informação sobre Mortalidade (SIM/DATASUS) de 2018 a 2022, focando em crianças menores de cinco anos que faleceram devido a causas evitáveis pela redução de ações relacionadas a promoção à saúde vinculadas a ações afirmativas na área da atenção primária no estado do Paraná. Resultados: No período analisado, o Paraná foi o estado do Sul com maior número de mortes em menores de cinco anos por causas evitáveis, devido à redução de ações de promoção a saúde na atenção primária. Esta dentre as causas de morte evitáveis é a segunda mais frequente. A macrorregional noroeste tem a maior taxa de mortalidade infantil e o ano com maior taxa foi em 2022. O principal fator foi por causas externas, sendo mais comum por inalação do conteúdo gástrico, a faixa etária mais acometida, foi entre 1 a 4 anos. Sexo masculino é o mais prevalente no geral. Conclusão: A variação nas taxas de mortalidade ressalta a importância de estratégias adaptadas às necessidades locais, incluindo promoção da saúde, imunização e cuidados emergenciais. Monitorar continuamente as tendências e ajustar políticas são fundamentais para melhorar os resultados em saúde infantil, evidenciando a influência positiva de políticas públicas alinhadas ao SUS.
