Published: February 2025

Conflict based on religious and belief differences is one of the longstanding SARA (ethnicity, religion, race, and inter-group relations) issues that persist to this day. Yet, all religions and beliefs come with noble teachings and bring messages of peace for all creation. The paradigm of religious moderation emerged as a perceived solution to various religion-motivated conflicts. This study aims to investigate whether religious moderation presented by policymakers and academics constitutes objective knowledge from Karl Mannheim's perspective and its relevance to strengthening national commitment. This research falls into the category of library research. The methodology employed is qualitative with philosophical and sociological approaches. The findings of this study are: First, moderate Islamic theology refers to the ideas and attitudes of believers who have a balanced and non-extremist view characterized by tawassuth (moderation), tawazun (balance), i'tidal (upright and firm), tasamuh (tolerance), and musawah (egalitarianism and non-discrimination). Second, the emergence of moderate Islamic theology is due to the socio-cultural conditions of society, security conditions, and academic reasons. Third, Mannheim's three types of meanings: Objective meaning, the government's response, and academics' perspectives are objective actions considering the contemporary social context that develops narratives of intolerance and radicalism. Expressive meaning, the narrative of moderate Islamic theology is also an expression of the actors or formulators of the moderate Islamic theology concept. Documentary, it means these actors are recorded in history as part of culture. Its relevance shows that the presence of moderate Islamic theology is needed to strengthen the commitment to the nation's four pillars. The recommendation from this research is that it can be used to strengthen the argument for national commitment through the philosophical concept of moderate Islam.

Published: February 2025

Background:

Orthopaedic surgery is a critical field, impacting global health-care expenditure and patient outcomes. Despite substantial research funding, issues of transparency and reproducibility persist, undermining the credibility of published in-print findings. Data-sharing initiatives aim to address these challenges by promoting accessibility and enhancing research reliability. We aimed to assess the landscape of data-sharing practices within the field of orthopaedic surgery, focusing on the top orthopaedic journals from 2020 to 2023.

Methods:

Original research articles from 10 of the top orthopaedic journals were screened and analyzed for data-sharing statements (DSSs). Furthermore, we identified variables that were influential on the inclusion of DSSs in orthopaedic clinical studies, and thematically analyzed DSS content to identify prevalent themes. Lastly, corresponding authors were contacted to assess their willingness to share their data.

Results:

Of the 1,084 reviewed articles, only 14% included a DSS. The Journal of Bone & Joint Surgery demonstrated the highest proportion of articles with a DSS. Over time, clinical trials exhibited an increasing trend in DSS adoption, contrasting with consistently low rates among cohort studies. Thematic analysis identified the gatekeeper role and conditional data availability as predominant themes in orthopaedic DSSs. Of the 115 emails sent to corresponding authors, only 22 (19.1%) yielded responses, and of those who responded, only 12 (54.5%) expressed a willingness to share their data.

Conclusions:

Our findings underscore a substantial disparity in data-sharing practices across orthopaedic journals, highlighting the need for standardization and mandates for DSSs. Adopting the Transparency and Openness Promotion (TOP) Guidelines can enhance accountability and foster a culture of open science within the field. By addressing these shortcomings, orthopaedic journals can improve research reproducibility and advance scientific knowledge effectively.

Published: February 2025

Humanity is putting unprecedented pressures on the Amazon forest systems due to global warming, deforestation, land-use change as well as large-scale infrastructure projects. Since the Amazon forest may possess a tipping point beyond which detrimental changes are self-propelling, these pressures could lead to system-wide state changes across major parts of the Amazon forest. We apply a dynamical systems model to assess the tipping risks and cascading transitions in the Amazon forest systems under different shared socio-economic emission and land-use change pathways (SSPs). For these emission scenarios, we constructed the according atmospheric moisture transports within the Amazon forest using a state-of-the-art moisture tracking model. Without deforestation, we find a critical threshold of 3.7-4.0°C of global warming where adaptive capacities of the forest may be surpassed such that around a third of the Amazon forest loses stability. However, when taking into account deforestation, our simulations robustly find a near system-wide tipping point of the Amazon forest (62-77% of the area) between 1.5-1.9°C of global warming and deforestation between 22-28%. These are values that humanity may reach already within the first half of this century, and possibly as early as in the 2030ies. Importantly, the large majority of the observed tipping events in our model (87-99%) are caused by knock-on effects from increasing drought intensities, leading to long-ranging and self-propelling cascading effects on scales of hundreds to thousands of kilometres. Overall, our results underscore the necessity to keep global warming to below 1.5°C as well as stop deforestation (around 15%) and restore these areas to avoid high tipping risks across the Amazon forest.

Authors: Sun Yanan , Jiang Luyao , Hu Yuru , Yang Jie
Published: February 2025

With institutional innovation as its core mission, pilot free trade zones are important channels that accelerate the green transformation of enterprises, a process essential for achieving sustainable development. Based on a quasi-natural experiment of pilot free trade zone policies, this research selects panel data of China’s A-share listed companies from 2008 to 2022 to empirically test the impact of these policies on the firms’ green transformation by using a multi-period difference-in-differences method. The findings show that pilot free trade zone policies significantly promote their green transformation. An effect test notes that these policies affect enterprises’ green transformation via financing constraints and green innovation level. Heterogeneity test results present that compared to enterprises and state-owned enterprises (SOEs) in the central and west regions, the green transformation effect of these policies on enterprises and non-SOEs in the east region is more significant. This paper offers valuable policy suggestions for promoting high-quality development of pilot free trade zones and guiding enterprises’ green transformation that contributes to sustainable and socially responsible growth.
Ultrasound Insights: Necrotic Choroidal Melanoma Presenting as Neovascular Glaucoma and intraocular inflammation
Authors: Yang Ye , Wu Xishi , Fang Wei
Published: February 2025

This report describes a case of necrotic choroidal melanoma in a 69-year-old woman presenting with neovascular glaucoma (NVG) and intraocular inflammation. Ultrasonographic evaluation, including B-scan and color Doppler imaging, revealed vitreous opacities, intraocular calcifications, necrotic areas without intralesional blood flow, and vascular bud-like signals at the scleral wall. These ultrasonographic findings provided critical diagnostic clues, distinguishing the condition from inflammatory intraocular diseases. Histopathology confirmed necrotic choroidal melanoma with over 50% necrosis and no evidence of orbital invasion. This case underscores the importance of ultrasonography in identifying necrotic choroidal melanoma presenting with NVG and inflammation.
Comparison of Ethanol-Iohexol Mixture and Ethanol-Lipiodol Suspension in Rabbit Renal Artery Embolization
Authors: Zhou Zijun , Jiang Hua , Liu Zhenyin , Zhang Jing , Li Haibo
Published: February 2025

Objective
To evaluate the efficacy and safety of an ethanol-iohexol mixture (EIM) as an endovascular embolic agent using a rabbit renal artery embolization model.
Methods
Thirty rabbits were randomly assigned to the EIM group or the ethanol-lipiodol suspension (ELS) group. Each rabbit underwent renal artery catheterization, followed by embolization with 1 mL of either EIM or ELS. Digital subtraction angiography (DSA) was performed immediately and five minutes post-embolization to assess vascular occlusion. Liver and kidney function tests were conducted at multiple time points (day 3, week 1, and week 2 post-embolization) to evaluate safety. After two weeks, the rabbits were sacrificed, and kidney specimens were collected for histopathological examination.
Results
Both EIM and ELS achieved effective and sustained vascular occlusion without evidence of collateral artery formation or recanalization. EIM was easier to inject and spread rapidly, whereas ELS, due to its higher viscosity, was more difficult to administer and separated within one minute. DSA imaging confirmed faster visualization of the embolization effect in the EIM group. Histopathological analysis confirmed thrombosis in the renal arteries of both groups, with no significant difference in the timing of occlusion. Liver function markers (ALT, AST) and kidney function markers (BUN, UA, β2-MG, Cystatin C) exhibited transient elevations post-embolization but returned to baseline over time.
Conclusions
Both EIM and ELS demonstrated effective and sustained renal artery embolization without recanalization. EIM, as a water-soluble, non-separating mixture, was easier to inject and provided rapid embolization, whereas ELS, with its higher viscosity, required greater injection force and exhibited phase separation. Despite differences in handling properties, both embolic agents achieved comparable vascular occlusion, with transient and reversible changes in liver and kidney function, indicating acceptable safety profiles.

Background
We previously reported that a major portion of trinucleotide two-repeat units (TTUs) are sites of unequal crossover and consequent colonization, that are massively spread and shared across the genomes of human and several other primates. These sites underscore the preference of AT- over CG-rich sequences, as recombination sites.
Methods
Here we extended our study to dinucleotides of AT/TA and CG/GC. An algorithm was designed to extract genomic regions with a higher probability of recombination. To this end, the algorithm consisted of dinucleotide 3-repeat units (D3Us), a portion of which was hypothesized to be the basic overlapping units, resulting from unequal crossover between dinucleotide two-repeat units (D2Us). We mapped TATATA, ATATAT, CGCGCG, and GCGCGC across the human genome, and analyzed their colonization (distance between consecutive D3Us < 500 bp). We also studied several colonies of various sizes in up to 100 vertebrates, using the UCSC and ENSEMBL Genome Browsers.
Results
We found 3,989,861 AT/TA and 95,849 CG/GC D3Us across the human genome, the majority of which resided in over 480,000 colonies, ubiquitously spread along all chromosomes. The AT/TA colonies were significantly larger and more intricate than CG/GC colonies. These colonies were mainly specific to, or of their largest size in human. D2Us and D3Us were the primary sites of unequal crossover in these colonies, resulting in the emergence of primary recombinants (overlaps among AT/TA repeats), ranging from 5- to 15-bp, and a vast repertoire of secondary recombinants (recombination among pure and primary recombinants), and eventually, colonies of exceeding intricacy and significance, based on Poisson distribution.
Conclusion
We report ubiquitous and intricate colonies of exceeding significance, in which D2Us and D3Us were the primary sites of unequal crossover and recombination. Across vertebrates, these colonies reached their maximum size in human. It is plausible that minimal DNA repeat sequences, such as D2Us, D3Us, and TTUs, mark recombination a ubiquitous rule across the human genome. This phenomenon may transform our perception of recombination, its magnitude, and biological and evolutionary consequences.

Published: February 2025

In this study, a new phospho-molybdic Kiggin-type polyoxometalate supported on silica-coated Fe3O4 nanoparticles (FS/PMo) with core-shell structure was prepared, and for detection of catalyst, XRD, FTIR, TEM, EDX, and VSM were applied. The catalyst was found to be excellent efficient to remove dibenzothiophene (DBT) by using hydrogen peroxide as the oxidant. The main operational parameters including dosage of the catalyst, temperature, and molar ratio of H2O2 and DBT in the reaction medium were assessed in the process, and the optimal reaction conditions were determined. a sulfur removal was achieved up to 99.53% under optimal reaction conditions. The catalyst was easily recoverable from the reaction medium by applying a magnet. The reusability of the catalyst was also tested by magnetic separation of the catalyst and reusing in the process. The suitable mechanism was also proposed for oxidative desulfurization of DBT using FS/PMo as the catalyst. To support experimental studies, Monte Carlo simulations combined with simulated annealing were applied to design FS/PMo nanocomposite for adsorption of DBT to form DBTO in the presence of H2O2 under the oxidative desulfurization.

Published: February 2025

In recent decades, viral outbreaks have significantly threatened global health, with herpes simplex virus type 2 (HSV-2) being one of the most prevalent infections. This study evaluated novel spiropyrimidine derivatives as potential antiviral agents against HSV-2, building on previous research that examined spirocyclic thiopyrimidinone derivatives against human coronavirus 229E (hCoV-229E). Among the eleven synthesized compounds, spiropyrimidinone derivative 3 demonstrated promising antiviral activity, with a selectivity index of 11.2. The drug mechanism of infection studies indicated that compound 3 primarily inhibits HSV-2 at the viral adsorption stage, achieving approximately 83% inhibition and reducing viral multiplication by 34%. Its efficacy is linked to its diketone moiety, which is known for its ability to enhance antiviral effects. Furthermore, the effect of compound 3 on viral inhibition is reflected in the level of caspase-3 protein expression, revealing that the apoptotic pathway is modulated. Docking studies revealed multiple interactions with herpes virus entry mediator (HVEM), indicating its potential as an entry inhibitor. These findings confirm that compound 3 could be a potential candidate for further development in HSV-2 antiviral therapy.

In conclusion, many different signaling pathways are involved in regulating IKs. Under baseline conditions the regulation is strongly [Ca2+]i-dependent, with PKA and CaM-CaMKII involved, whereas during ß-adrenergic stimulation it is [Ca2+]i-independent and supposes a pivotal role of EPAC-mediated activation of CaMKII.
Sympathetic activation robustly increases the slow delayed rectifier K+ current (IKs) in the mammalian ventricular myocardium, however, exact downstream pathways involved in the β-adrenergic regulation of the current are not fully elucidated yet.
This study examined the Ca2+ sensitivity of IKs and the contribution of the protein kinase A (PKA) and the calcium/calmodulin kinase II (CaMKII) pathways in regulating IKs in isolated canine ventricular myocytes. Experiments were carried out under ß-adrenergic receptor activation (10 nM isoproterenol) and under baseline conditions (without isoproterenol). IKs was measured as an HMR-1556 sensitive current with the action potential voltage clamp technique under the physiological intracellular calcium homeostasis of the cells.
Reducing intracellular Ca2+ concentration ([Ca2+]i) with 1 µM nisoldipine decreased the peak and mid-plateau densities of IKs, reduced the current integral, and increased the time-to-peak value. In contrast, ß-adrenergic receptor activation by isoproterenol resulted in larger IKs densities and integral, and shorter time-to-peak value. These effects of isoproterenol on IKs were significantly smaller when the CaMKII inhibitor 1 µM KN-93 was present in the cells, but the PKA inhibitor 3 µM H-89 did not exert such effect. Importantly, all effects of isoproterenol on IKs have fully developed even in the presence of 1 µM nisoldipine.
Under baseline conditions the mid-plateau density of IKs, was significantly smaller in the presence of KN-93, H-89 or nisoldipine, while peak IKs density and the current integral were significantly smaller only in nisoldipine.

Published: February 2025

Additive Manufacturing (AM), also known as 3D printing, using high temperature thermoplastics has been proposed for the production of structures in space. To determine whether this is feasible a systematic study investigating the impact of the space environment on the AM process must be conducted. Existing investigations have focussed on AM in microgravity and AM of either low temperature thermoplastics or individual high temperature thermoplastics at low pressure. This study examines the mechanical characteristics of high temperature, space compatible thermoplastic parts produced by AM in a low pressure environments. Four different thermoplastic filaments were investigated - poly ether ether ketone (PEEK), poly ether ketone ketone (PEKK), and two types of polyetherimide (PEI) (ULTEM 9085 and ULTEM 1010). Their mechanical performance, internal structures and crystallinity were compared to those manufactured under atmospheric conditions. It was observed that the low pressure enabled the manufacture of ULTEM 1010 specimens, which could not be achieved in ambient atmosphere. The low pressure additionally improved the inter-layer adhesion of PEEK and ULTEM 9085 specimens. PEEK, PEKK and ULTEM 1010 specimens exhibited bubbling when printed under low pressure conditions, most noticeable in the compression and H-90° samples, resulting in worse mechanical properties than samples manufactured in atmosphere. The mechanical performance of bending and H-0° specimens remained consistent irrespective of the printing environment, this was thought to be due to conduction to the print bed being the dominant form of heat transfer, resulting in similar thermal histories.

Learning and Thinking styles are the ways students take in process and remember information. The present study was undertaken to know the effect of learning and thinking styles on academic achievement of secondary school students. Academic achievement was treated as dependent variable whereas learning and thinking styles are independent variables. Both the hemisphere of brain and their functions consider knowing the holistic performances of the students. Locality, Gender and Type of school were treated as background variables. A sample of 240 secondary school students was selected through multi-stage random sampling technique. Style of Learning and Thinking (SOLAT) test developed by Venkataraman (2011) was used to measure learning and thinking style of students in terms of their hemisphericity functions of the brain. The obtained data were analyzed using Three Way ANOVA with 2Ã—2Ã—2 factorial design. Levines Test of Homogeneity of Variance was also applied to test the assumption of homogeneity of variance for ANOVA. Main effects of learning and thinking style, locality and gender on academic achievement of secondary school students were found to be significant. Significant interaction effect of learning & thinking style and locality learning & thinking style and gender was reported on academic achievement of secondary school students. The findings of the present study have an implication for teachers that they should find out the domain part of their students brains first and then use the appropriate classroom techniques, methods and tools according to them only then better and greater learning can be accomplished. Results of the study revealed that Active Learning Styles were effective in enhancing the Thinking Styles and Academic Achievement among the secondary school students. The study also showed a positive significant correlation between Thinking Styles and Academic Achievement among Secondary school students.

Published: February 2025

The excessive existence of N, P, and COD in surface water may well promote eutrophication. Therefore, the development of methodologies capable of removing the excess amount of these nutrients from water sources is of significant importance. This study introduces a novel hybrid adsorbent that integrates nano CaO2 with lignin nanoparticles, combining the oxidative properties of CaO2 with the abundant and cost-effective lignin to achieve efficient simultaneous N, P, and chemical oxygen demand (COD) removal. Hence, this study presents the development of a hybrid adsorbent composed of nano CaO2 and lignin nanoparticles for simultaneous N, P, and COD removal from water environments. The developed nanocomposite was capable of removing phosphorus over a broad pH range and the optimal performance was obtained at neutral pH. The nanocomposite showed fast elimination kinetics of around 64 min. The findings obtained from the treatment of a real sewage water sample showed that the CaO2@lignin could remove 94.62% (=6.09 mg/g), 96.35% (=35.13 mg/g), and 73.09% (=352.54 mg/g) of -P, -N, and COD, respectively. Current research reveals the multifunctional nature of the CaO2@lignin nanocomposite, which exhibits broad pH tolerance, high removal efficiencies, and rapid elimination kinetics without the need for external energy inputs or complex equipment.

Published: February 2025

Introduction. This article introduces a new instrument aimed at addressing various synthetically integrated process formations and their effects that underlie the challenges of personal reflection on emotions as an intrapersonal predictor of emotional health development. The research objective was to develop and validate a diagnostic methodology for assessing difficulties in personal emotional reflection (DPER). Methods. The study involved 1688 participants (62.26% female, 37.74% male) aged 15 to 60 years. The development of DPER methodology statements was based on an author's model of research tools, presented by three components that encompass seven parameters (scales). Unformed abilities to understand and express one's emotions (difficulties in recognising one's own feelings, difficulties in expressing emotions); susceptibility to emotional stress (inability to endure (tolerate) emotions; tendency to use physiologically oriented defenses); psychological mechanisms hindering effective emotional reflection (prohibitions on emotions; suppression of emotions; avoidance of emotions). Convergent validity of the methodology was tested using: The Emotional Regulation Questionnaire (Gross, 2003), the Diagnostic Methodology for the Value and Self-efficacy of Emotional Control (Mauss, 2010), the Emotional Intelligence Test (Lyusin, 2006), and The Brief Five-factor Personality Questionnaire (Gosling, Rentfrow & Swann, 2003). Statistical data analysis included the calculation of Cronbach's alpha coefficient, Kaiser-Meyer-Olkin criterion, Bartlett's sphericity coefficient, Pearson's criterion; exploratory factor analysis was conducted. Results. A sufficient level of reliability of the correlation matrix characterising the questionnaire's structure and internal consistency of its scales was determined. The grouping of scales into factors corresponds to the proposed model of the research tool: a three-component structure (66.85% explained variance) encompassing seven parameters (scales) (62.15% explained variance). Convergent validity of six questionnaire scales was confirmed. Discussion. The DPER methodology is an independent, reliable, and valid instrument, allowing for the measurement of the degree of difficulties in personal emotional reflection over a relatively short period and making a probabilistic forecast for the development of emotional health conditions.

Published: February 2025

Em meio as grandes ocorrências de doenças crônicas, consideradas por alguns especialistas como um dos grandes problemas de saúde do século XXI, o Diabetes Mellitus se destaca, visto que cada paciente apresenta necessidades diferentes, sejam alimentares, físicas e/ou psicológicas. Diante desta realidade, é necessário que o paciente diabético tenha acesso a informações que estejam de acordo com a sua realidade de vivência com a doença, o que irá garantir que a informação adquirida por ele é relevante e, de fato, vai contribuir com seu tratamento. Dessa forma é preciso conhecer o paciente, sua realidade, seus interesses e aspectos que influenciam na sua saúde. Além disso, é imprescindível que as informações quem cheguem ao paciente sejam seguras e não forneçam dados errôneos, o que pode acarretar complicações em sua saúde. Diante do exposto, este trabalho tem como objetivo o desenvolvimento de uma Rede Social, que integrada a um sistema de aprendizagem informal voltado também para a saúde, o MobiLEHealth, utiliza as ferramentas da Web Semântica para coletar dados de pacientes diabéticos e, com base nos seus perfis, recomenda conteúdos que auxiliam nos seus tratamentos. Para garantir que estas informações recomendadas sejam seguras e oriundas de fontes confiáveis, foi desenvolvido juntamente com a Rede Social um Sistema de Intermédio do Especialista, que permite que um profissional de saúde possa avaliar os conteúdos e as fontes que podem ser recomendados aos pacientes. Ao final do desenvolvimento, estes sistemas foram submetidos a um teste com usuários reais. Com essa validação, percebeu-se a relevância que eles apresentam, bem como a importância da implementação destes ambientes no cotidiano de um paciente diabético e de um profissional de saúde.

Published: February 2025

São cada vez mais comum problemas multirrótulos onde um rótulo pode ser atribuído a mais de uma instância, sendo chamados de problemas de classificação multirrótulo. Dentre os diferentes métodos de classificação multirrótulo, podemos citar os métodos BR (Binary Relevance), LP (Label Powerset) e RAkEL (RAndom k-labELsets). Tais métodos são ditos métodos de transformação do problema, pois consistem em transformar o problema multirrótulo em vários problemas de classificação tradicional (monorrótulo).A adoção de comitês de classificadores em problemas de classificação multirrótulo ainda é algo muito recente, com muito a ser explorado para a realização de pesquisas. O objetivo deste trabalho é realizar um estudo sobre a construção de comitês de classificadores multirrótulos construídos através da aplicação das técnicas de aprendizado semissupervisionado multidescrição, a fim de verificar se aplicação desse tipo de aprendizado na construção de comitês acarreta melhorias nos resultados. Os comitês de classificadores utilizados nos experimentos foram o Bagging, Boosting e Stacking como métodos de transformação do problemas foram utilizados os métodos BR, LP e Rakel e para a classificação multirrótulo semissupervisionada multidescrição foi utilizado o Co-Training. Ao fim das análises experimentais verificou-se que a utilização da abordagem semissupervisionado apresentou resultados satisfatórios, uma vez que as duas abordagens supervisionada e semissupervisionada utilizadas no trabalho apresentaram resultados semelhantes.

Background

Predictors of tooth loss in Indonesians have not been identified. This prediction is very useful for tooth loss prevention in middle-aged and elderly.

Objective

The study aimed to predict tooth loss in the middle-aged and elderly populations based on sociodemographic and systemic disease.

Methods

A cross-sectional study of secondary data from the National Basic Health Research was conducted on a sample of 16,973 respondents following the inclusion criteria. Sociodemographic and systemic diseases as independent variables and tooth loss as a dependent variable were assessed. Data were analyzed using a logistic regression model.

Results

Respondents with at least one missing tooth were 20.6%. Among them, 55.6% were females, and 68.1% belonged to the pre-elderly age group (49.0% lived in urban areas and 51.0% lived in rural areas). Only 30.5% had tertiary education, and 61.2% held a formal job. History of systemic diseases like diabetes, heart disease, hypertension, stroke, and cancer were found to be in 5.4%, 3.7%, 17.3%, 2.3%, and 0.4% of respondents. The predictive value of tooth loss was 0.976, and the range was > 0.5. In this study, the predictive value of the respondents' tooth loss was 1.

Conclusion

Indonesian tooth loss predictor value in middle-aged and elderly populations based on sociodemographic and systemic disease was found to be 1. This value indicates a risk of tooth loss. The predictive factor influencing tooth loss of 80.2% can be predicted based on age, occupation, and history of diabetes mellitus and heart disease. Tooth loss can be predicted if the sample is in the elderly group who are still working and have a history of diabetes and heart disease.

Background

Skin cancers exist as the most pervasive cancers in the world; to increase the survival rates, early prediction has become more predominant. Many conventional techniques frequently depend on visual review of clinical information and dermoscopic illustrations. In recent technological developments, the enthralling algorithms of combining modalities are used for increasing diagnosis accuracy in deep learning.

Methods

Our research proposes a multi-faceted approach for the prediction of skin cancer that incorporates clinical metadata with dermoscopic visuals. The pre-trained convolutional neural networks, like EfficientNetB3, were used for dermoscopic images along with transfer learning techniques to excavate some of the visual attributes in this study. Moreover, TabNet was used for processing the clinical metadata, including age, gender, and medical history. The features obtained from both fusion techniques were integrated to enhance the prediction accuracy. The benchmark datasets, like ISIC 2018, ISIC 2019, and HAM10000, were used to assess the model.

Results

The proposed multi-faceted system achieved 98.69% accuracy in the classification of skin cancer, surpassing the model that used dermoscopic snapshots with clinical data. The convergence of images with clinical metadata has substantially enhanced prediction resilience, demonstrating the importance of multimodal deep learning in skin lesion diagnosis.

Conclusion

This research focused mainly on the efficiency of integrating dermoscopic visuals and clinical information using transfer learning for skin cancer prediction. The proposed system offers a promising tool for improving diagnostic accuracy, and further research could explore its application in other medical fields requiring multimodal data integration.

Published: February 2025

Esta pesquisa analisou os discursos de posse de Luiz Inácio Lula da Silva em 2003, 2007 e 2023, com o objetivo de compreender a presença do ethos, do pathos e do logos, conforme a definição aristotélica, e verificar, também, se era possível encontrar sentidos semelhantes nas sequências discursivas nos três discursos. Para isso, como suporte metodológico, foi utilizada a Análise de Discurso de linha francesa. Os resultados demonstraram que haviam sentidos discursivos semelhantes, especialmente em temas como gratidão, democracia, luta social, combate à desigualdade, educação, saúde e união nacional.

Abstract
This research analyzed the inaugural speeches of Luiz Inácio Lula da Silva in 2003, 2007, and 2023, aiming to understand the presence of ethos, pathos, and logos, according to Aristotelian definitions. It also sought to determine whether similar meanings could be found in the discursive sequences across the three speeches. To this end, French discourse analysis was used as a methodological support. The results demonstrated that there were similar discursive meanings, especially on themes such as gratitude, democracy, social struggle, combating inequality, education, health, and national unity.
Keywords: discursive meaning; rhetoric; Luiz Inácio Lula da Silva; political communication.

Published: February 2025

Este estudo tem por objetivo compreender a construção da imagem pública, no campo político-eleitoral, a partir das publicações na rede social Instagram, durante a campanha eleitoral presidencial de 2022, focando, exclusivamente, no candidato Luiz Inácio Lula da Silva (Lula), do Partido dos Trabalhadores (PT), vencedor do pleito. Por meio da Análise de Conteúdo (AC), foram mapeadas 418 publicações e construídas quatro categorias, mas, que, neste extrato de uma pesquisa mais ampla, somente duas foram apresentadas: Acontecimentos e Figuras Públicas. A partir da análise, identificou-se o uso da rede social como espaço de autorrepresentação, para divulgar principalmente meta acontecimentos, em postagens que criam vínculos imagéticos e referenciais.
