Authors: Alkaabi Khaula , Mehmood Kashif , Bhatacharyya Parama , Aldhaheri Hassa
Published: August 2023

The importance of Education for Sustainable Development (ESD) in influencing students’ understanding of and behavior toward sustainability cannot be overstated. However, prior studies have shown that students generally lack comprehension of how to apply geography instruction in relation to territories and their contribution to the Sustainable Development Goals (SDGs). Although the relationship between the SDGs and academic institutions has been the subject of numerous research, it is still unknown how much knowledge students have on the subject. Therefore, this research aims to raise awareness about SDGs and evaluate the knowledge of undergraduate geography students regarding the SDGs. Additionally, it investigates the impact of Spatial Data Infrastructure (SDI) and quality education as pedagogical tools on students’ sustainability consciousness. A questionnaire was designed, validated, and administered to students at the United Arab Emirates University from both geography and non-geography cohorts to assess their knowledge. Statistical analysis indicated high reliability of the constructs. The results revealed significant insights through descriptive, ANOVA, and multiple comparisons analysis with the Tukey HSD test. Specifically, geography students who participated in an SDG Awareness and Knowledge Program within the Technological Pedagogical Content Knowledge (TPACK) model demonstrated statistically significant differences in various aspects of SDG awareness and knowledge, SDG awareness using SDI skills, and the importance of quality education and the integration of SDG knowledge in pedagogy, as compared to other geography and non-geography students who did not receive the SDG awareness program. This research is expected to provide valuable knowledge about SDGs through effective pedagogical skills, benefiting both student and educator community.
A Comparative Study on the Spatial Layout of Hui-Style and Wu-Style Traditional Dwellings and Their Culture Based on Space Syntax
Authors: Cen Kejie , Rao Xiaoxiao , Mao Zhuoxun , Zheng Xiangyong , Dong Dier
Published: August 2023

Hui-style and Wu-style traditional dwellings adopt different connection modes, reflecting different spatial characteristics and resulting in different spatial layout characteristics. The rationale for this is related to the differences between the two schools of Confucianism culture: the Huizhou culture emphasizes the commercial application of Confucianism and pays more attention to the idea of commercialization, and the space exhibits a certain degree of freedom, while the Wuzhou culture emphasizes the official application of Confucianism and pays more attention to the idea of officialization, and the space is more systematic compared to Hui-style traditional dwellings, more profoundly articulating the traditional notions of propriety. Therefore, this paper attempts to explore the correspondence between the spatial layout of traditional dwellings and Confucianism culture through a comparative analysis of the spatial layout characteristics of the two schools of traditional dwellings, and to provide reference for similar studies.

Authors: Shiweda Markus , Shivute Fillipus , Sales Ana Raquel , Pereira Mário J.
Published: August 2023

Climate change and anthropogenic factors’ impact on habitat loss is a growing problem that is influencing unsustainable wildlife local-population home range shifts and triggering an increase in human–wildlife conflict (HWC). Yet, keystone species involved in HWC such as elephants play a vital role in nature-based ecosystem services and have important economic and cultural value to the people that are living with them. To understand how climate change and anthropogenic factors affect habitat loss and elephants’ home range shift, the movement of Namib desert-dwelling elephants was monitored and observed in the Ugab River basin between February 2018 and November 2020 at fortnight intervals. There are 87 elephants in the Ugab River basin that are distributed into two subpopulations: desert-dwelling elephants (N = 28) and semi-desert-dwelling elephants (N = 59). To achieve the objective of the study, land cover change, elephant movement, rainfall, and temperature data were analysed using ArcGIS spatial and statistical tools, such as image analysis, optimised hot spot analysis (OHSA), and cost distance analysis, to distinguish habitat vegetation changes and home range shifts and how these link to emerging human–elephant conflict (HEC) hot spots. Human farming activities, poor rainfall, and frequent droughts are responsible for the loss of habitat of around 73.0% in the lower catchment of the ephemeral river streams; therefore, the urgency of conserving and sustaining these habitats and desert-dwelling elephants is discussed here.
The Influence of Overburden Stress and Molding Water Content on the Microstructure of Remolded Loess
Authors: Qi Zhiyu , Li Zhiqing
Published: August 2023

This study aims to reveal the mechanisms of the microstructural evolution of remolded loess under different molding water contents and overburden stresses. Utilizing L6 loess from Yan’an, remolded soil specimens were fabricated under various pressures and moisture contents, followed by conducting one-dimensional consolidation tests. The macroscopic porosity, pore size distribution curves (PSD), and microstructure of these remolded loess samples were examined. Experimental findings indicate that an increase in molding water content leads to an augmentation in macroscopic pore volume and elongated pore shapes, concurrently exerting substantial influence on the primary pore size and pore volume of both macropores (>0.4 μm) and minipores (0.4–4 μm), with minimal impact on micropores (<0.4 μm). The escalation of overburden stress solely contributes to the reduction in pore size and pore volume of macropores. Variations in the Menger fractal dimension occur only beyond the optimal water content, while overburden stress exhibits a minimal effect on the Menger fractal dimension. Furthermore, remolded loess exhibited a certain yield stress, and when the overburden stress was lower than the yield stress, there was almost no change in various types of pores. Finally, a microstructural evolution model of remolded loess under different molding water contents and overburden stresses was proposed. These findings are expected to provide new insights into the microstructural evolution and deformation mechanisms of loess in high embankment construction sites.

Published: August 2023

At present, the conservation of the environment represents an objective that everyone wants to achieve. The construction industry has influenced the advancement of alternative materials that comply with sustainable development. In this article, reinforced concrete was obtained by mixing 80% blast furnace slag and 20% fly ash. These concentrations were chosen because they provide the lowest porosity in the cementitious matrix. Rice husk ash was used as an activator. Guadua angustifolia fibers were used to evaluate the mechanical performance of the concrete. The composition of the raw material was determined by X-ray fluorescence, the microstructure of the fibers by AFM, and the SEM technique was used to determine the surface characteristics of guadua fibers and concrete mixes. The structural characterization using XRD, the structure of the molecules of the guadua fiber, and the composition of the mixture’s molecular mixtures were determined by FTIR spectroscopy. Its properties, such as tensile strength and flexural strength, were analyzed. The results indicated that the concrete with the addition of Guadua angustifolia fibers. The results indicated that the concrete with the addition of guadua angustifolia fibers showed the best mechanical behavior. Tensile strength was optimized, establishing values of 2.68 MPa for unreinforced concrete and up to 3.12 MPa for fiber-reinforced concrete. The flexural strength values increase at ages after 28 days due to the pozzolanic reaction generated. Values of 2.8 MPa were obtained for concrete without fiber and 3.5 MPa for concrete reinforced with guadua angustifolia fiber.
How Paradoxical Leadership Promotes Employees’ Career Sustainability: Evidence from the Chinese Cross-Border E-Commerce Industry
Authors: Li Qi , Chin Tachia , Peng Benjian
Published: August 2023

The ultra-fast development of digital technologies exerts immense pressure on employees in the cross-border e-commerce (CBEC) industry, especially those who are older and have lower levels of education. These employees may appear resistant to digital technologies, which can harm their careers. Leadership can address negative mentalities and sustain employees’ career development. Using job demands–resources (JD–R) theory, this study explored how paradoxical leadership can increase employees’ career sustainability by mitigating resistance to digital technology. Additionally, the moderating effects of age and education were examined. We analyzed time-lagged data from 141 employees in the Chinese CBEC industry, employing Partial Least Squares–Structural Equation Modeling (PLS–SEM) to test the hypothesized model. Our results revealed that: (1) paradoxical leadership relates negatively to resistance to digital technology but positively to career sustainability; (2) resistance to digital technology negatively relates to career sustainability; (3) resistance to digital technology partially mediates the relationship between paradoxical leadership and career sustainability; (4) age positively moderates the negative relationship between resistance to digital technology and career sustainability, while education negatively moderates that relationship. We offer novel insights into the trade-off effects among the five variables. Furthermore, our study provides practical guidance for firms, emphasizing the critical influence of paradoxical leadership and individual characteristics on ensuring employees’ career sustainability in the Chinese CBEC context.

Published: August 2023

With the progress of urbanization in China, the energy-saving renovation of a large number of existing buildings, especially old buildings, has become an important project for the green and low-carbon development of urban renewal. This paper takes the old brick school building in a university in Chengdu as an example. Through field research, the existing problems of the building are analyzed in detail in terms of building function, structure and appearance, and a detailed plan for functional upgrading, structural reinforcement and façade renovation is drawn up, taking into account the actual requirements and environmental status. In addition, solar photovoltaic technology is integrated into the renovation of the building’s pitched roof. Through modelling and analysis, the amount of solar energy captured by the photovoltaic roof is quantitatively simulated and the dynamic energy-saving potential of the renovation project under changing actual meteorological conditions is pre-evaluated. The preliminary results indicate that such green renovations can contribute to about 164,066 kWh annual solar energy collection and the self-use electricity from the PV roof accounts for 42–76% of total energy consumption, leading to about 60% building energy consumption conservation. The payback period of such a renovation program is assessed to be about 1.9 years, which is quite economically feasible considering the local energy tariff policy. This paper explores the feasibility and design direction of green and low-carbon renovation and upgrading of old buildings, which can provide a reference for the application of green and low-carbon renovation of local old buildings.
The Control of Microplastic Pollution in Semi-Closed Seas: Good-Faith Cooperation and Regional Practice
Authors: Ma Mingfei , Liu Xinyang
Published: August 2023

The impacts of microplastic (MP) pollution in the marine environment have already been illustrated by natural science. The issues resulting from MPs have revealed the problem of the current international governance arrangement, and international agreements are found to be inadequate to curb the growing MP pollution. This article explores reasons for the failure of governance cooperation from legal normativism and positivism. By analyzing the semi-closed sea system in the UNCLOS, this article concludes that the principle of good faith makes it possible to moderate geographic political tensions during cooperation and help reach an agreement on matters of mutual concern. Then, from the perspective of regional ocean governance, propose strategies for states bordering semi-enclosed seas and others to gradually control MP pollution in the marine environment through legal and policy measures.

Published: August 2023

Table salts with their specialty flake size, textures, flavors, and colors can be considered a gastronomy niche food already increasing in demand worldwide. Being unrefined, they can contain trace elements potentially both healthy and toxic. In this study, 12 mineral elements (Al, Ca, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) in 10 different salts commercially available in southern Italy namely, Atlantic grey, Baule volante, Guerande, Hawaiian pink, Hawaiian black, Himalayan pink, Maldon, Mozia, Persian blue, and smoked salts were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) and thermal decomposition amalgamation-atomic absorption spectrophotometry (TDA-AAS). The concentration of mineral elements was variable according to the type of salt and its geographical origin. Co, Cr, Cu, Hg, Pb, and Se levels were tolerable and Al, Ca, Fe, Mn, Ni, and Zn ranged significantly among the samples. Persian Blue and Atlantic Grey salts showed elevated levels of Fe and Zn; their intake can be helpful in some specific conditions. Nevertheless, Ni levels were high in Persian Blue and Smoked salts. Pb exceeded the maximum level in all samples. Additional monitoring analyses of mineral contents in table salts are recommended for human health.

The Ebola virus and its close relative, the Marburg virus, both belong to the family Filoviridae and are highly hazardous and contagious viruses. With a mortality rate ranging from 23% to 90%, depending on the specific outbreak, the development of effective antiviral interventions is crucial for reducing fatalities and mitigating the impact of Marburg virus outbreaks. In this investigation, a virtual screening approach was employed to evaluate 2042 natural compounds for their potential interactions with the VP35 protein of the Marburg virus. Average and worst binding energies were calculated for all 20 poses, and compounds that exhibited binding energies <−6 kcal/mol in both criteria were selected for further analysis. Based on binding energies, only six compounds (Estradiol benzoate, INVEGA (paliperidone), Isosilybin, Protopanaxadiol, Permethrin, and Bufalin) were selected for subsequent investigations, focusing on interaction analysis. Among these selected compounds, Estradiol benzoate, INVEGA (paliperidone), and Isosilybin showed strong hydrogen bonds, while the others did not. In this study, the compounds Myricetin, Isosilybin, and Estradiol benzoate were subjected to a molecular dynamics (MD) simulation and free binding energy calculation using MM/GBSA analysis. The reference component Myricetin served as a control. Estradiol benzoate exhibited the most stable and consistent root-mean-square deviation (RMSD) values, whereas Isosilybin showed significant fluctuations in RMSD. The compound Estradiol benzoate exhibited the lowest ΔG binding free energy (−22.89 kcal/mol), surpassing the control compound’s binding energy (−9.29 kcal/mol). Overall, this investigation suggested that Estradiol benzoate possesses favorable binding free energies, indicating a potential inhibitory mechanism against the VP35 protein of the Marburg virus. The study proposes that these natural compounds could serve as a therapeutic option for preventing Marburg virus infection. However, experimental validation is required to further corroborate these findings.

Epstein–Barr virus (EBV) is a well-known risk factor for the development of nasopharyngeal carcinoma, Hodgkin’s lymphoma (HL), and Non-Hodgkin’s lymphoma (NHL). People with HIV infection (PWH) are at increased risk for EBV-associated malignancies such as HL and NHL. Nevertheless, there are limited data on the burden of EBV among this population group in Ethiopia. Hence, this study aimed to determine the burden of EBV infection among adult HIV-positive individuals in Ethiopia and assess the determinants of EBV DNA positivity. We conducted a cross-sectional study at the Tikur Anbessa Specialised Hospital from March 2020 to March 2021. Two hundred and sixty individuals were enrolled in this study, including 179 HIV-positive and 81 HIV-negative individuals. A structured questionnaire was used to capture demographic and individual attributes. In addition, the clinical data of patients were also retrieved from clinical records. EBV viral capsid antigen (VCA) IgG antibody was measured by multiplex flow immunoassay, and EBV DNA levels were tested by quantitative real-time polymerase chain reaction (q-PCR) assays targeting the EBNA-1 open reading frame (ORF). Descriptive statistics were conducted to assess each study variable. A multivariable logistic regression model was applied to evaluate the determinants of EBV infection. Statistical significance was determined at a p-value < 0.05. Two hundred and fifty-three (97.7%) study participants were seropositive for the EBV VCA IgG antibody. Disaggregated by HIV status, 99.4% of HIV-positive and 93.8% of HIV-negative participants were EBV seropositive. In this study, 49.7% of HIV-positive and 24.7% of HIV-negative individuals were EBV DNA positive. PWH had a higher risk of EBV DNA positivity at 3.05 times (AOR: 3.05, 95% CI: 1.40–6.67). Moreover, among PWH, those with an HIV viral load greater than 1000 RNA copies/mL (AOR = 5.81, 95% CI = 1.40, 24.13) had a higher likelihood of EBV DNA positivity. The prevalence of EBV among PWH was significantly higher than among HIV-negative individuals. Higher HIV viral loads in PWH were associated with an increased risk of EBV DNA positivity. Since the increases in the viral load of EBV DNA among PWH could be related to the risk of developing EBV-associated cancers, it is necessary for more research on the role of EBV in EBV-associated cancer in this population group to be carried out.
Discovery of Hepatitis E and Its Impact on Global Health: A Journey of 44 Years about an Incredible Human-Interest Story
Authors: Khuroo Mohammad Sultan
Published: August 2023

The story of the discovery of hepatitis E originated in the late 1970s with my extreme belief that there was a hidden saga in the relationship between jaundice and pregnancy in developing countries and the opportunity for a massive epidemic of viral hepatitis, which hit the Gulmarg Kashmir region in November 1978. Based on data collected from a door-to-door survey, the existence of a new disease, epidemic non-A, non-B hepatitis, caused by a hitherto unknown hepatitis virus, was announced. This news was received by the world community with hype and skepticism. In the early 1980s, the world watched in awe as an extreme example of human self-experimentation led to the identification of VLP. In 1990, a cDNA clone from the virus responsible for epidemic non-A, non-B hepatitis was isolated. Over the years, we traversed three eras of ambiguity, hope, and hype of hepatitis E research and conducted several seminal studies to understand the biology of HEV and manifestations of hepatitis E. Many milestones have been reached on the long and winding road of hepatitis E research to understand the structure, biology, and diversity of the agent, changing the behavior of the pathogen in developed countries, and the discovery of a highly effective vaccine.
Unravelling Relationships between In Vivo Effects on Plants and Detected Pesticide Mixtures in Freshwaters of a South-European Agro-Ecosystem
Authors: Silva Emília , Narciso Guilherme Anágua , Castro Joel Carvalho
Published: August 2023

The multiple benefits agriculture provides to society depend on the long-term sustainable management of water resources, including the preservation of a good ecological and good chemical status of the water bodies. Presently, this good chemical status has not been reached in the majority of European river basins. Implemented monitoring strategies are targeted to identify the presence and magnitude of the ecological impacts that come from mixtures of chemicals but fail to give information on the causes of the ecosystem disruptions. This work aims to contribute to assessing the quality of surface waters used for irrigation in the LGVFX agricultural area (Central Portugal) by applying non-conventional in vivo phytotoxicity tests on three primary producers, a monocotyledon (Sorghum saccharatum) and two dicotyledons (Lepidium sativum and Sinapsis alba), complemented by chemical screening and mixture-risk modelling with component-based methods (summation of risk quotients) based on the classic concept of concentration addition (CA). Although inhibition percentages of the phytotoxicity parameter germination and root and shoot growth may be related to the presence of mixtures of pesticides, it was not possible to establish the fingerprinting of the detected compounds with the observed biological effects, mostly due to the large gap of ecotoxicological data on terrestrial plants exposed to contaminated water. In addition, pesticides can interact within the plant, leading to antagonism and synergism phenomena.

Land Use and Land Cover (LULC) properties give vital information about pollution signatures in rivers, and they help develop best management practices (BMPs) for effective water resource management. This work employs multivariate statistical methods, receptor modeling, connectivity analysis, and univariate trend analysis to investigate pollution sources across spatiotemporal scales in the Manawatu River, New Zealand. A positive matrix factorization (PMF) method was applied to interpret possible contamination sources. A 25-year dataset (1989–2014) comprising 12 water quality variables from three sites was used. Runoff connectivity analyses identified high-producing grassland (HG) as the most dominant pollution class in all sub-catchments. Univariate analyses revealed that nutrients and sediments were higher than in the initial monitoring years. The PMF analysis found possible pollutants causing impairment, which required attention from waste managers. PMF also showed that point, natural, and agricultural sources significantly contributed to pollution downstream of the river. In the midstream, the erosion, point, and agricultural sources were significant contributing factors. Agricultural pollution and soil erosion were the main contributors to the upstream sub-catchment area. This study suggests that BMPs with a high retention capacity are needed in specific locations in the catchment area to filter high concentrations of pollutants generated.

The article is devoted to the issues of the dialogue of cultures and spiritual, moral, and life purpose values of modern youth. Currently, integration and globalization have a decisive influence on all spheres of human life — the economy, culture, education, and upbringing. Today we live in the reality of the 21st century — the century of digitalization and informatization, which has significantly changed the culture and stratification of society. At the same time, we must understand that our youth is not homogeneous or uniform. It is a mirror reflection of the social pyramid that exists in Kazakhstan. Ultimately, as elsewhere, we have both "golden youth" and "outsiders", there is urban, rural, unemployed, and self-employed youth. The youth can be politically active, marginal, and passive, cosmopolitan and conservative, secular-minded and religious. Therefore, it is crucial to understand the values that guide young people and largely determine their culture, ideas about the present, their life strategies and plans for the future. The article deals with a complex of ideological, conceptual, theoretical, and socio-cultural issues related to the socio-philosophical and cultural aspects and considering political socialization and culture as an integral characteristic of the social sphere of life of modern Kazakhstani society. The genesis, structure, dynamics, institutional forms, and normative value content of the political socialization and culture of the youth of Kazakhstan, conditioned by the national traditions of political culture, are analyzed.

An Effective Hybrid Encryption Model using Biometric Key for Ensuring Data Security
Authors: Arumugam Saravanan
Published: August 2023

Cybersecurity becomes a key concern in many applications as cybercrimes exploit system weaknesses. Cryptography helps protect sensitive data in everyday transactions and communications using passwords or tokens. However, the power of the encryption/decryption algorithms always depends on their ability to secure the data in any situation. This paper presents an effective hybrid encryption/decryption model that makes use of a biometric key along with an effective password to ensure data security. The biometric key utilised in the proposed model is generated from the fingerprint, which is a unique physical characteristic of an individual. The model initially encodes the data to be securely transmitted. The symmetric key encryption that makes use of a biometric key is applied over the encoded data. Another layer of defence is built by applying asymmetric key encryption to the encrypted data along with the details of the fingerprint. The Advanced Encryption Standard (AES) algorithm and Elgamal Encryption using Elliptical Curve Cryptography (E3C2) are used for symmetric and asymmetric encryptions. Experimental analysis is performed to analyse the model's computing speed and security and is compared with existing models and encoding/encryption techniques

Published: August 2023

In today's world, fires in homes and commercial places are a serious problem that can harm the local environment as well as jeopardize people's property and lives. This study predicts the sensor dataset gained from an integrated sensor framework with an artificial neural network. The major goal of this research was to identify a convenient way to encode input data that balanced information loss with simplicity. This paper developed an Artificial Neural Network (ANN) model and applied it to the fire dataset collected from the Integrated Sensor System (ISS). Every neuron of the model will learn and hold weights that weigh information, which provides better accuracy. To mitigate loss functions and improve accuracy, various activation functions such as Sigmoid, Relu, and optimizer Stochastic Gradient Descent (SGD), Adam, and Adamax are used in the designed model. The results demonstrated that the prediction accuracy of the ANN model with Adam as the optimizer is better than that of the other two optimizers. The findings also show that the ANN model performs well in terms of prediction accuracy and is also better suited to the sensor fire dataset

O Brasil apresentou aumentos significativos nas taxas de parto cesárea. Ao todo, 57,6% dos nascimentos registrados no país de janeiro a outubro de 2022 foram por cesariana, de acordo com o Ministério da Saúde. O dado preliminar indica que é a maior taxa da história, muito acima dos 15%, índice recomendado pela Organização Mundial da Saúde.Este estudo é uma revisão bibliográfica, foi realizada uma  busca dos artigos utilizando as bases de dados eletrônicas PubMed/MEDLINE e Scielo. Além disso, foram utilizados os DeCS  (Health  Sciences  Descriptors) “Cesaria”, e “Desnecessárias” estes foram associados através do operador booleano AND e por fim, foram selecionados 11 artigos. Nesse viés, por se tratar de  uma cirurgia, a cesariana apresenta riscos para a mãe como embolia pulmonar, hemorragias, infecções, trombose, risco de internação em UTI, aderência de alças intestinais e bexiga no útero, lesões na bexiga , redução da fertilidade, sangramento uterino anormal e dor pélvica crônica, além de maiores riscos de gravidez em cicatriz de cesariana, rotura uterina e acretismo placentário.Além disso, entre os possíveis dos conceptos nascidos, citam-se alterações no microbioma intestinal,  maiores taxas de disfunções imunológicas e desordens metabólicas (como obesidade e asma) e cognitivas (como hiperatividade). Logo, faz-se necessária a promoção de medidas governamentais que visem diminuir os índices da cesaria.

O esôfago de Barret (EB) é uma patologia pouco estudada na população pediátrica, caracterizada pela presença de metaplasia colunar no esôfago inferior. Apresenta associação com o desenvolvimento de uma das neoplasias mais frequentes do esôfago nessa faixa etária, o adenocarcinoma esofágico. Diante do risco 10 vezes maior de desenvolver a neoplasia supracitada nos pacientes com o EB, há necessidade de avaliar o melhor método para realizar o diagnóstico precoce. O objetivo do presente trabalho foi descrever os fatores de risco relacionados à presença do EB e o seu diagnóstico adequado na faixa etária pediátrica. Trata-se de um estudo do tipo revisão bibliográfica, em que foram utilizadas as bases de dados PUBMED, LILACS e MEDLINE com os descritores “ BARRET´S ESOPHAGUS” e “PEDIATRIC” e o operador booleano “AND”. Após isso foram aplicados os filtros da plataforma, os critérios de inclusão e exclusão. O EB apresenta alguns fatores que predispõem o seu aparecimento, tais como o IMC elevado para idade e o refluxo gastroesofágico crônico. Além desses, existem outros, como alterações neurológicas e traqueoesofágicas, próprias da população pediátrica. Sabe-se que os sintomas não são específicos da doença e podem não refletir a gravidade histológica do quadro, por isso a importância do diagnóstico e acompanhamento endoscópico para avaliar o prognóstico dessas crianças, quanto aparecimento do adenocarcinoma esofágico.

O recurso à Oxigenoterapia Nasal de Alto Fluxo tem aumentado no uso do tratamento a doentes com Insuficiência Respiratória Aguda com Covid 19, contudo, ainda é muito recente ter dados relativos à sua utilização. Explorar e mapear a evidência científica disponível sobre as vantagens do uso de Oxigenoterapia Nasal de Alto Fluxo no tratamento da Insuficiência Respiratória Aguda Secundária à Covid 19, nos adultos, em contexto hospitalar. Scoping review segundo a metodologia do Joanna Briggs Institute (JBI). A pesquisa incluiu todo o tipo de publicações sobre o tema disponíveis na EBSCO e na B-On, em todas as línguas, entre 1 de janeiro e 13 de novembro de 2020. Foram incluídos 8 artigos na revisão, os quais destacam o facto de a Oxigenoterapia Nasal de Alto Fluxo tem como vantagens o conforto e a tolerância resultando numa boa adaptação por parte do doente, permitindo fornecer altas concentrações constantes de oxigénio aquecido e humidificado, melhorando a eficácia da ventilação e oxigenação. Este método quando associado ao decúbito ventral, pode reduzir a necessidade de Entubação Oro Traqueal. É necessária mais evidência científica sobre esta temática de forma a garantir a eficácia e segurança na utilização da Oxigenoterapia Nasal de Alto Fluxo na Insuficiência Respiratória Aguda por Covid-19 nos adultos, sendo aconselhado a utilização deste método em quarto com pressão negativa, apesar da aerossolização ser reduzida.

Introdução: Apesar do expressivo crescimento da Fonoaudiologia, ainda existem lacunas importantes de conhecimento de várias especialidades. Partindo do princípio de que o uso de recursos audiovisuais corrobora com a visibilidade da profissão e ainda contribui no processo de formação dos estudantes,  este relato tem por objetivo relatar a experiência sobre a prototipagem de recursos audiovisuais por estudantes para o público em geral. Metodologia: Trata-se de relato de experiência desenvolvido por graduandos do curso de Fonoaudiologia de uma universidade pública de Pernambuco. O percurso metodológico foi estruturado em três fases a saber: 1- Imersão teórica; Workshop sobre ferramentas da web para criação de recursos digitais; 3- Prototipagem e  pesquisa de satisfação. Os resultados foram analisados a partir de técnicas de estatística descritiva. Resultados: A  idade média de dos nove participantes foi de 27,3 anos. Todos optaram por trabalhar com conteúdo visuais dinâmicos. A grande maioria ficou satisfeito com o tema abordado para criação do recurso e sobre a capacitação oferecida para a criação do respectivo conteúdo. Sobre a trilha de aprendizagem a grande maioria realizou pesquisa em fontes de informação geral (sites) para construir os recursos.De um modo geral, pontuaram que a experiencia foi positiva e referiram que a abordagem metodológica utilizada se tratou de algo inovador e/ou moderno. Conclusão: Os estudantes se mostraram satisfeitos com a criação de recursos digitais. Por fim, pode-se concluir que experiências exitosas como esta, podem contribuir, impulsionar e corroborar o protagonismo estudantil no processo de aprendizagem, principalmente na educação superior em saúde.

Microglia participate in neurological homeostasis, as a mediator of neurogenesis and synaptic modulation events, programmed cell death, neuronal stabilization and remodeling. The recent discoveries, have shown that the failure to suppress these events, or the hyperactivation of the microglia population, implies the appearance of a series of pathological injuries to the Central Nervous System.
Gestão das escolas secundárias nas cidades de Maputo, Beira e Nampula

Este artigo resulta da pesquisa realizada nas escolas secundárias do 1º ciclo, nas cidades de Maputo, Beira e Nampula e visa analisar a gestão das escolas na perspectiva dos directores. Como procedimento metodológico, usamos a pesquisa qualitativa e descritiva associada ao estudo de caso. Optámos pelo estudo de caso por considerá-lo apropriado à análise de fenómenos sociais complexos e por possibilitar a apreensão de características holísticas do fenómeno estudado (Yin, 2001). Como instrumentos de recolha de dados, aplicamos entrevista semiestruturada a 6 directores das escolas públicas. Os resultados desta pesquisa mostram-nos que a área pedagógica funciona com dificuldades devido à falta de autonomia dos directores na tomada de certas decisões e, como corolário disso, há carência de insumos pedagógicos. Na gestão administrativa-financeira, as escolas carecem de recursos humanos e financeiros. Na gestão de espaços, em algumas escolas, os espaços não são agradáveis e nem acolhedores para o Processo de Ensino e Aprendizagem devido à má localização das infraestruturas escolares.

Published: August 2023

A alimentação é essencial para a vida do ser humano. Desde a antiguidade até os tempos atuais os alimentos passaram por grandes transformações, porém ainda possuem a mesma essência de suprir a fome momentânea da população. Os alimentos acompanham a evolução da sociedade, fazem parte da rotina, desde estarem presentes em grandes acontecimentos a refeições rápidas do modo de vida da sociedade contemporânea. A partir da Revolução Industrial percebe-se grandes mudanças nas refeições, tais como comidas congeladas, ultra processadas, rápidas e de fácil acesso ganham espaço na cozinha mundial. É imprescindível que a indústria alimentícia busque novas tecnologias e inovações para atender as novas tendências e necessidades da população. Conforme a FIESP 2020, os alimentos se subdividem em categorias: sensorialidade e prazer, saudabilidade e bem-estar, conveniência e praticidade, confiabilidade e qualidade, sustentabilidade e ética, nas quais a população busca tendências alimentares que trazem benefícios a saúde, prevenindo doenças, aumentando a qualidade de vida e bem-estar.

A indústria da acetona é majoritariamente demandada pelo setor de solventes e vem apresentando uma tendência de crescimento nos últimos anos. A rota para obtenção da acetona é feita a partir da desidrogenação do isopropanol, e a reação de conversão acontece em um reator com leito fixo. Falhas neste equipamento podem diminuir a eficiência do processo, segurança operacional, riscos ao meio ambiente, e até mesmo em um acidente catastrófico. Por isso, é de suma importância conhecer os possíveis riscos do processo, e ter dados para possíveis ações de prevenção. Neste trabalho foi feita a análises de risco no reator, seguindo o método HAZOP e método Árvore de Eventos. A partir do método HAZOP, identificou-se os principais eventos que causariam uma consequência extremamente perigosa, como uma possível explosão do reator, que foram o superaquecimento e a sobrepressão do equipamento. Com esta conclusão, realizou-se uma análise quantitativa, através de uma Árvore de Eventos onde obteve-se uma taxa de 0,04 explosões por ano para o caso de ocorrência de superaquecimento ou sobrepressão do equipamento. Para o caso de interrupções do processo, obteve-se uma taxa de ocorrência de 0,36 por ano, ou seja, uma ocorrência possível a cada 2,78 anos.

Alienação parental na prática pediátrica: revisão integrativa do conceito
Authors: Palhares Dario , Dos Santos Íris Almeida , De Melo Magaly Abreu de Andrade Palhares
Published: August 2023

Objetivo: atualizar o estado da arte do debate conceitual acerca do tema da alienação parental. Fontes dedados: artigos de revisão, artigos de meta-análise, dissertações de mestrado e teses de doutorado, em bases de dados, do período de 2015 a 2021. Síntese dos dados: O debate atual se compõe dos elementos acerca da definição do fenômeno da alienação parental; contraposições e objeções ao conceito e implicações do conceito de alienação parental para o profissional de saúde. Essencialmente, trata-se da atitude da criança em passar a rejeitar um genitor ou familiar quando do distanciamento de convívio, seja pelo divórcio, seja por outros motivos. Tal comportameto decorre de uma triangulação de um familiar alienador, do familiar alienado e da criança. Como objeções, há que de diferenciar atos de alienação parental perpetrados pelos adultos do comportamento da criança, pois algumas são mais suscetíveis e outras mais resilientes. Conclusões: houve acirramento recente do debate, pois o termo ‘alienação parental’ vigorou na versão inicial da nova Classificação Internacional de Doenças – CID 11 - mas foi revogado. No entanto, os elementos da alienação parental encontram-se codificados nos códigos relacionados a problemas familiares, de modo que tais questões já não são atinentes somente ao âmbito judicial, mas também aos profissionais de saúde que lidam com crianças.
