The impact of the social digital influencer on the attitudinal change of his virtual community
Authors: Settou Hind , Aomari Amina
Published: February 2025

In an environment that has become entirely connected, the phenomenon of digital influencers is proving to be a relevant and appropriate practice in today's context of digital transformation. Perceived as a key player in social change, the digital influencer has become a veritable electronic opinion leader, constantly inspiring, raising awareness and shaping the opinions, beliefs, mentalities and, consequently, attitudes and purchasing behavior intentions of his or her community. The aim of this research is dual: on the one hand, to highlight social influencer marketing, given the scarcity of studies carried out in the Moroccan context; on the other, to analyze the social role of the digital influencer, focusing on a myriad of skills that characterize his profile and the content disseminated through the engagement of his virtual community. The innovative aspect of this research lies in the proposal of a mixed theoretical model with a rich and complementary interdisciplinary overlap, combining the ELM model of information processing derived from social psychology theories of persuasion and the model of reasoned action drawn from management sciences and referring to consumer behavior. The research methodology adopted is based on descriptive methods supported by documentary analysis techniques, as well as an exploratory qualitative study involving a sample of 32 creators of socially-oriented content, chosen according to the principle of semantic diversification and saturation. The data collected through interviews will then be compared with statistical data from the instagram platform, the subject of our study, to concretize and measure the research parameters studied.

Published: February 2025

O curso de Medicina da Universidade Regional de Blumenau passou por mudanças em sua grade curricular em 2019, modificando a distribuição de disciplinas e acrescentando a Integração Básico-Clínica. Assim, o novo currículo utiliza uma combinação de Metodologia Tradicional com Ativa, uma novidade aos acadêmicos, que muitas vezes estão acostumados apenas ao método clássico de ensino. Tal fato, atrelado à pandemia vivenciada globalmente, pode ser considerado como um estressor dos acadêmicos de medicina. Deste modo, a pesquisa objetivou buscar conhecimento dos índices de estresse, depressão e ansiedade nos discentes do ciclo básico. Trata-se de um estudo transversal, que utilizou a Depression, Anxiety and Stress Scales (DASS-21) a fim de analisar os efeitos com a mudança curricular. A análise dos dados coletados demonstrou que a busca por acompanhamento psicológico não foi prevalente durante o período, enquanto a prática de atividade física esteve presente na rotina de mais de 70% dos acadêmicos. Ademais, a quantidade de horas diárias extras destinada a estudos esteve no intervalo de 2 a 4 horas. A junção destes fatores pode ter sido a responsável pelos índices das variáveis estarem sem alterações na maioria dos acadêmicos abordados, como demonstrou o resultado do DASS-21. Sendo assim, infere-se que a mudança curricular e a pandemia não afetaram significativamente a saúde mental dos estudantes de medicina do ciclo básico do segundo semestre de 2021.
The 10 milestones and pitfalls of a researcher's career: the binomial between scientific research and teaching in favor of acculturation
Authors: Oliveira Ricardo
Published: February 2025

The career of researcher is fundamental for the scientific evolution of Health. Naturally, there are moments of some sadness and injustice, namely regarding the basis that underlies the funding of research projects. But research is a gift and the ultimate brain lift, which generates and transforms knowledge into practical solutions, ensuring significant and sustainable advances in global health. In this thanking editorial to all authors and reviewers for 2024, I share my experience of how binomial research versus teaching was fundamental in my scientific acculturation. It is my goal that this reflection on milestones can inspire the generations of young people I have helped to professionalize. It is my vision for scientific acculturation that implies not only the technical learning of a set of scientific concepts, but also the internalization of a mindset that values critical thinking, cross-cutting curiosity in the area of knowledge, and the search for evidence and the application of the scientific method in problem solving.

Economic Aspects of Rough Turning of Wide Grooves Based on Surface Roughness Measurement
Authors: KOLODZIEJ Marek
Published: February 2025

The purpose of this article is to present the results of the analysis of the surface roughness parameters for different grooving strategies in S355J2 steel. The analysis was carried out based on basic and additional roughness parameter values, which allow for a more comprehensive assessment of the functional features of the measured surfaces. The results show that the surface structure of the machined surfaces is relatively homogeneous for the tested material. The negative skewness coefficient (Ssk) was obtained for the deep and dynamic methods, indicating significantly greater friction in relation to the trochoidal strategy. The smallest fractal dimension was obtained for the trochoidal strategy, which suggests the highest stability of the machining process. The tool utilization efficiency in the depth strategy was reduced by as much as 40%, and the tool cost per product series decreased from €2.75 per tool in deepth machining to €1.65 in trochoidal machining.

Retrieving cloud-base height and geometric thickness using the oxygen A-band channel of GCOM-C/SGLI
Authors: Nagao Takashi M. , Suzuki Kentaroh , Kuji Makoto
Published: February 2025

Abstract. Measurements with a 763 nm channel, located within the oxygen A-band and equipped on the Second-generation Global Imager (SGLI) on board the Japan Aerospace Exploration Agency (JAXA) Global Change Observation Mission – Climate (GCOM-C) satellite, have the potential to retrieve cloud-base height (CBH) and cloud geometric thickness (CGT) through passive remote sensing. This study implemented an algorithm to retrieve the CBH using the SGLI 763 nm channel in combination with several other SGLI channels in the visible, shortwave infrared, and thermal infrared regions. In addition to CBH, the algorithm can simultaneously retrieve other key cloud properties, including cloud optical thickness (COT), cloud effective radius, ice COT fraction as the cloud thermodynamic phase, cloud-top height (CTH), and CGT. Moreover, the algorithm can be seamlessly applied to global clouds comprised of liquid, ice, and mixed phases. The SGLI-retrieved CBH exhibited quantitative consistency with CBH data obtained from the ground-based ceilometer network, shipborne ceilometer, satellite-borne radar, and lidar observations, as evidenced by sufficiently high correlations and small biases. These results provide practical evidence that the retrieval of CBH is indeed possible using the SGLI 763 nm channel. Moreover, the results lend credence to the future use of SGLI CBH data, including the estimation of the surface downward longwave radiative flux from clouds. Nevertheless, issues remain that must be addressed to enhance the value of SGLI-derived cloud retrieval products. These include the bias of SGLI CTH related to cirrus clouds and the bias of SGLI CBH caused by multi-layer clouds.

Thus, the concept of museum marketing encompasses a range of practices and decisions aimed at enhancing the appeal of the museum’s services, and ensuring a significant number of visitors. To achieve this effectively, museums must adopt the visitor’s perspective, analyze their needs, and tailor services accordingly. To boost service appeal, museums must respond promptly and accurately to visitors’ inquiries. Consistency in implementing marketing policies is crucial, and their effectiveness should be assessed through both quantitative and qualitative measures.
Examining How Regulation Shapes Euthanasia Practice in Belgium: A Qualitative Study of the Literature and Health Professionals’ Perspectives
Authors:   , Archer Madeleine
Published: February 2025

Belgium has one of the longest-standing assisted dying or ‘euthanasia’ regulatory frameworks internationally, but despite this, how this practice is regulated, and how regulation shapes practice had not been comprehensively examined. This thesis by published papers applied regulatory theory to investigate how regulation shapes euthanasia in Belgium. This research identified that the Belgian euthanasia regulatory space is ‘polycentric,’ reflecting the fragmented nature of regulatory authority within this framework. This regulatory model has a range of implications for practice, specifically, for clinicians’ euthanasia decision-making, the quality and consistency with which euthanasia care is provided, and for the control of euthanasia practice.
An Investigation on the In-Plane Performance of Shear Walls for Low to Moderate Seismic Regions
Authors:   , Ghaseminia Seyed
Published: February 2025

This thesis examined the performance of reinforced masonry (RM) and reinforced concrete (RC) shear walls, which are essential for protecting buildings during earthquakes. By analysing walls with single and double layers of reinforcement, the study assessed their strength, ductility, drift, and vulnerability through experimental tests, analytical models, and advanced simulations. The findings revealed that RM walls with limited ductility outperformed non-ductile RC walls and demonstrated comparable resilience and drift capacity to limited ductile RC walls. This emphasised the potential of RM walls as a reliable and resilient option for earthquake-resistant design in low to moderate seismic regions such as Australia.

Определены особенности хрупкого разрушения поршней ДВС комбинированного металла: алюминиевого литейного сплава, армированного бандажной вставкой жаропрочного чугуна. Фрактографическим анализом изломов выявлены дефекты сплавления основного металла поршней и закладного бандажного кольца. Причина возникновения инцидента обусловлена: стеснением значительных температурно-силовых деформаций при теплосменах разнородного металла с различными теплофизическими свойствами и неудачной формой чугунной вставки. Она носит комплексный характер, сочетающий низкий уровень проектирования поршней и изготовления армированных отливок, в которых, при эксплуатации, возникают высокие температурные напряжения – в металле поршня и закладной детали.

The features of brittle fracture of ICE pistons made of combined metal: aluminum casting alloy, reinforced with a heat-resistant cast iron bandage insert are determined. Fractographic analysis of fractures revealed defects in the fusion of the base metal of the pistons and the embedded bandage ring. The cause of the incident is due to: the constraint of significant temperature-force deformations during thermal changes of a dissimilar metal with different thermal-physical properties and an unsuccessful shape of the cast iron insert. It is complex in nature, combining a low level of piston design and manufacturing of reinforce

УПРАВЛЕНИЕ ПРОЦЕССОМ КРИСТАЛЛИЗАЦИИ АЛЮМИНИЕВЫХ СПЛАВОВ В ПРОСТРАНСТВЕ СОСТОЯНИЙ
Authors: Денисов М.С. , Петрешин Д.И. , Чеботарев П.А.
Published: February 2025

В настоящей статье речь идет о технологии, использующей давление в качестве дополнительного термодинамического параметра, который наряду с концентрацией легирующих элементов, температурой и временем создает пространство переменных состояний расплава, и перевод расплава в сильнонеравновесное состояние, когда число возможных сценариев перехода в твердое состояние неизмеримо возрастает по сравнению с традиционными технологиями. Для достижения поставленных целей разработан алгоритм работы системы управления, управление процессом кристаллизации предлагается осуществлять в соответствии с моделью в пространстве координат: температура, давление, время. На примере сплава В95 установлено, что, останавливая процесс на разных стадиях, можно получать свойства сплава с различным сочетанием структурных и, как следствие, физико-механических свойств.

In the presented work, we are talking about a technology using pressure as an additional thermodynamic parameter, which, along with the concentration of alloying elements, temperature and time, creates a space of variable melt states, and the transfer of the melt to a strongly non-equilibrium state, when the number of possible scenarios for transition to a solid state increases immeasurably compared with traditional technologies. To achieve these goals, an algorithm for the operation of the SU has been developed, it is proposed to control the crystallization process in accordance with the model in the coordinate space: temperature, pressure, time. Using the example of alloy B95, it was found that by stopping the process at different stages, it is possible to obtain alloy properties with a different combination of structural and, as a result, physico-mechanical properties.

Abstract: This study aims to evaluate the wear rate of Mg-Hydroxyapatite-based composites reinforced with rare earth oxide (Neodymium oxide) under in-vitro physiological conditions along with mechanical and microstructural evaluations. To analyze the wear rates of the composites, an innovative technique has been designed to perform experiments on the fabricated samples. The counter disc used for interaction was stainless steel disc coated with the same material as the samples. The analysis was performed under different loading conditions with different sliding velocities considering the different compositions of rare-earth oxide (1%, 1.5%, and 2%). The samples were fabricated via powder metallurgy route with compaction pressure of 250 MPa followed by sintering at 400 °C for 2 Hrs. Moreover, the mechanical analysis was done by calculating the samples’ microhardness and ultimate tensile strength. In contrast, the materials were characterized and synthesized employing FTIR, FESEM, XRD, and EDS techniques. The lowest wear rate was observed when the samples were subjected to higher load and lower velocities. Also, it was found that during progressive wear testing, the wear rate is maximum in the initial stage, but with the increase in sliding distance, the wear rate tends to reduce and then become steady. In addition, it was found that Mg-HA-1.5Nd2O3 showed the highest wear resistance. Moreover, the microhardness of the sample with a rare-earth concentration of 1.5% was higher as compared to other samples. Similar results were obtained for ultimate tensile testing of the composites. FESEM images showed refined microstructure of the samples, with EDS results showing the homogenous distribution of HA and REO particles. XRD analysis showed the development of secondary β-phases that interlocks grain boundaries. Hence, the designed experimental setup provides extensive wear rate results with related conditions created when the implant is placed inside the physiological environment.

Abstract: Drilling carbon fibre reinforced polymers (CFRP) often causes several kinds of damage around the hole, such as delamination, which is considered one of the main issues that may occur when drilling the CFRP laminate. It significantly decreases the structural strength of the composite material and reduces its long-term performance. Using support plates and stacked materials as layers on the composite material has been identified as one of the main methods often used to reduce delamination. This research investigates the variations in delamination, fibre pull-out, thrust force, drilling torque, circularity and diameter error when drilling with and without adhesive tape layers. Furthermore, the research paper also explores the effect of varying drilling conditions and drill bit geometries on those output parameters. It has been revealed from the results that the proposed use of both adhesive tape layers and support plates can significantly limit delamination and fibre pull-out damages, thereby achieving a better-quality hole when drilling CFRP, as opposed to just using adhesive tape layers.

O Brasil é o segundo maior país em população de animais de estimação, com cerca de 150 milhões de pets, sendo a maioria cães. Durante a pandemia de COVID-19 o setor de pet shops foi considerado essencial, o que contribuiu para o crescimento desse número. Hoje, cães e gatos são tratados como membros da família, o que aumentou a preocupação com sua saúde e longevidade. Como resultado, o envelhecimento dos pets trouxe o surgimento de doenças como as cardiopatias, que afetam aproximadamente 85% dos animais com mais de 13 anos. Diagnosticar essas condições é crucial, e exames como o ecocardiograma e o eletrocardiograma são indispensáveis. No entanto, esses exames exigem conhecimento especializado e consideram variáveis como espécie, raça e peso. Embora existam vários aplicativos móveis voltados para a medicina veterinária, ainda não há um específico para cardiologia veterinária. Diante disso, o desenvolvimento de um aplicativo móvel que facilite a organização, atualização e arquivamento de laudos ecocardiográficos e eletrocardiográficos em cães e gatos é proposto. Esse recurso atenderia à crescente demanda por tecnologia na veterinária, proporcionando mais precisão e eficiência no cuidado dos animais.

Rodovias localizadas em áreas urbanas são protagonistas de diversos impactos negativos relacionados à saúde e ao bem-estar da população. O ruído proveniente do tráfego de veículos contribui para o aumento da poluição sonora. Na cidade de Maringá, Estado do Paraná, Brasil, o Contorno Norte passa pelo interior de alguns bairros, caracterizando-se como um trecho de travessia urbana, expondo a comunidade ao ruído dele proveniente. Este trabalho teve como objetivo avaliar o impacto da poluição sonora em um trecho desta travessia urbana, tendo como metodologia: monitoramento acústico, mapeamento de ruído e simulação acústica. Os resultados do monitoramento e do mapa acústico elaborado apresentaram níveis sonoros superiores aos limites estabelecidos em norma. O Índice de ruído de tráfego (TRF) e o nível de poluição sonora (Lnp) ficaram acima dos limites recomendados. A simulação da implementação de medidas mitigadoras envolvendo redução da velocidade de tráfego, construção de barreiras acústicas e aplicação de materiais com propriedades absorsoras implicou em resultados que indicam melhora do cenário acústico na área de estudo, passando-se a atender os requisitos de norma em quase todos os pontos. Conclui-se que é necessário que a administração pública implemente medidas mitigadoras com o objetivo de proteger a população exposta aos ruídos provenientes deste tipo de via.

Published: February 2025

Diesel remains a globally essential fuel, especially in transportation, yet its sulfur content poses significant environmental and health risks by forming sulfur oxides (SOx) during combustion. This study presents a mathematical modeling and kinetic analysis of diesel hydrodesulfurization (HDS) as a sustainable solution to produce cleaner fuels. Using catalysts such as Co-Mo/γ-Al₂O₃ in fixed-bed and trickle-bed reactors operating between 300–425°C and 1–20 MPa, the research simulates sulfur removal reactions involving thiophene, benzothiophene (BT), and dibenzothiophene (DBT) present in Libyan crude diesel. Models developed in Polymath and Excel compare kinetic expressions, notably the Langmuir-Hinshelwood-Hougen-Watson (LHHW) and power-law models, with findings indicating that the model corresponding to Equation 2 (Model II) best predicts reactor performance. The study also contrasts HDS with alternative desulfurization methods—such as biodesulfurization, adsorptive, oxidative, and extractive approaches—highlighting HDS’s superior efficiency and refinery compatibility despite challenges in deep desulfurization. Furthermore, the analysis identifies an optimal operating condition at approximately 383°C and 7.33 MPa, balancing catalytic efficiency with durability. Evaluations of catalyst effectiveness and diffusion limitations via the Thiele modulus reinforce the need for optimized catalyst design. Overall, the research underscores the potential of targeted process optimization to enhance sulfur removal, contributing to cleaner diesel fuels and improved environmental health.

Published: February 2025

This study examines the influence of principals' emotional intelligence and leadership qualities on teacher performance in high schools in Aceh Barat. Using a quantitative approach and multiple regression analysis, the research investigates how these factors individually and jointly contribute to teacher effectiveness. Emotional intelligence, encompassing self-awareness, empathy, and social skills, was found to have a positive impact on teacher performance, as principals with high emotional intelligence foster a supportive work environment. Leadership also demonstrated a significant positive effect, with principals who actively guide, motivate, and communicate effectively with their staff contributing directly to improved teaching outcomes. Notably, the combined influence of emotional intelligence and leadership amplified these effects, explaining 74.1% of the variance in teacher performance. These findings suggest that both emotional intelligence and leadership are essential qualities in educational leaders, as their interaction maximizes teacher performance. The study highlights the need for leadership training programs that develop both attributes to optimize teaching and learning outcomes. Future research could further explore how specific dimensions of emotional intelligence and leadership styles interact to influence performance in various educational contexts.

Corporate Social Responsibility (CSR) has become a mandatory practice for companies, including those in the palm oil industry, which plays a significant role in the global economy. However, inconsistent accounting treatments for CSR expenditures have raised challenges in achieving transparency and accountability. This study examines the variations in CSR accounting practices among palm oil companies listed on the Indonesia Stock Exchange and their implications for financial transparency, stakeholder trust, and corporate sustainability. The findings reveal that companies adopt diverse approaches to reporting CSR expenditures, treating them as operating expenses, tax-related costs, or long-term investments. While some companies integrate CSR into sustainability initiatives aligned with global standards like ISPO and RSPO, others treat CSR as a compliance obligation. This inconsistency underscores the absence of explicit accounting standards for CSR, creating challenges for investors, auditors, and policymakers in assessing the impact of CSR activities. This study highlights the need for harmonised regulations and standardised CSR reporting practices to enhance financial transparency and accountability. By addressing these gaps, companies can strengthen stakeholder trust, improve corporate reputation, and contribute to the long-term sustainability of the palm oil industry.
