Authors: Appezzato Mariana Martins , Avila Clara Regina Brandão de
Published: October 2024

ABSTRACT Purpose Investigate if speech perception skills can differentiate school children with Specific Reading Disorders (SRD) with and without Persistent Speech Sound Disorders (PSSD). Methods 80 children, regularly enrolled in the 2nd (N=1), 3rd (N=28), 4th (N=29), 5th (N=15) and 6th (N=7) grades participated in the study. Control Group (CG) (N=48): no complaints, no speech alteration; and Resarch Group (RG) (N=32) – with SRD, RGI (N=15) without PSSD and RGII (N=17) with PSSD. Two tests evaluated auditory input reception: Simplified evaluation of auditory processing; and Perception task of nonwords, with Portuguese language structure (DNPLS). Data was analyzed by: Likelihood Ratio Test, Kruskal-Wallis test, Dunn test with Bonferroni correction, Mann-Whitney test, Spearman correlation, and construction of a ROC curve to obtain a threshold value for the correct answers in the perception of non-words test. Results Control and RGI showed higher correct answer scores than RGII. There was no difference between the correct answer distributions of the Control and RGI, and RGI and RGII in the test of DNPLS and the number of correct answers in the CG was higher than in the RGII. Conclusion The ability to discriminate non-words enabled the differentiated between school-aged children with SRD associated with PSSD and typical children, thus characterizing this group for presenting a number of correct answers lower than 30.5, considering the task proposed to discriminate non-words. These results suggest that the presence of PSSD worsens the performance in speech perception of the schoolchildren with SRD.

RESUMO Objetivo Investigar se a habilidade de percepção de fala pode diferenciar escolares com Transtorno específico de aprendizagem (TAp) com e sem Transtorno Persistente dos Sons da Fala (TPSF). Método Participaram da pesquisa 80 crianças, regularmente matriculadas no 2º (N=1), 3º (N=28), 4º (N=29), 5º (N=15), e 6º (N=7) anos, assim reunidos: Grupo Controle (N= 48) - sem queixas, sem alteração de fala; e Grupos Pesquisa (N = 32) - com TAp, sendo GPI (N = 15) sem TPSF e, GPII (N = 17), com TPSF. Duas provas avaliaram input auditivo: Avaliação simplificada do processamento auditivo; e Tarefa de percepção de pseudopalavras com estrutura da língua portuguesa - TDP. Os dados foram analisados pelos testes: Razão de Verossimilhanças, Kruskal-Wallis, Dunn com correção de Bonferroni, Mann-Whitney, correlação de Spearman, além da construção de uma curva ROC para obter um valor de corte para o número de acertos na prova de percepção de não palavras. Resultados Controle e GPI mostraram maiores escores de acerto que GPII. Não houve diferença entre as distribuições de acertos do Controle e GPI e do GPI e GPII na TDP e o número de acertos do GC foi maior que o do GPII. Conclusão A habilidade de discriminação de pseudopalavras diferenciou os escolares com TAp e TPSF das crianças sem TPSF, caracterizando, assim esse grupo por apresentar número de acertos menor que 30,5, considerada a tarefa proposta para discriminar pseudopalavras. Esses resultados sugerem que a presença do TPSF piorou o desempenho em percepção de fala dos escolares com TAp.
A falta que fala
Authors: Mendes Cleise Furtado
Published: October 2024

Resumo: Este artigo revisita algumas teorias em que a melancolia é vista como posição subjetiva intrinsecamente relacionada à vertente poética da experiência humana, observando certas mutações históricas do conceito e buscando flagrar expressões desse vínculo em exemplos da poesia lírica e dramática. A peça O rinoceronte, de Ionesco, encenada pela primeira vez em 1959, na Alemanha, pode ser lida como alegoria das vicissitudes sociais e afetivas de cidadãos vivendo em qualquer tempo-espaço dominado pelo pensamento totalitário. Por esse trajeto interpretativo, a peça expõe os riscos da inércia e do fatalismo melancólico e nos oferece a imagem vívida de um paralelo inquietante, quando projetada sobre certas cenas de convívio humano na vida brasileira dos últimos anos.

Published: October 2024

Resumo As práticas de Promoção de Saúde Mental em escolas são descritas na literatura internacional como modelo de comprovada eficiência. Entretanto, ainda são escassos os estudos brasileiros dedicados ao tema, sobretudo no âmbito da articulação intersetorial entre os CAPSi e o setor escolar. Neste estudo, parte-se do pressuposto de que um dos principais entraves evidenciados nesta articulação remete à baixa apreensão, por parte das redes de atenção psicossocial, sobre os desafios de ordem psicossocial presentes nas escolas. Portanto, esta pesquisa investigou, por meio de grupos focais, quais são, na percepção de profissionais de uma escola pública do Rio de Janeiro, os principais desafios e potencialidades latentes no ambiente escolar, com vistas a fundamentar a elaboração de iniciativas de promoção de saúde mental em escolas. Os resultados apontam que a violência e os conflitos escolares constituem os principais desafios a serem enfrentados. Como forma de enfrentá-los, destaca-se a superação das barreiras de contato entre as diferentes culturas presentes na escola, o incremento e a democratização da participação de alunos e familiares no cotidiano escolar, e a colaboração intersetorial permanente entre a rede psicossocial e a rede escolar.

Published: October 2024

Abstract This article presents the development of EducaIndex as an innovative and dialogical methodological proposal, which allows the evaluation of communication campaigns on HIV/AIDS and viral hepatitis by young people aged 15 to 24, linked to schools, civil society, scholars, professionals and/or managers, enabling mediation between health education, information, and communication. Data was collected in Brasília-DF and Catalão-GO in the Central-West region; Manaus-AM in the North region; Vitória-ES in the Southeast region; Porto Alegre, Santa Cruz do Sul and Fontoura Xavier-RS in the South region; and Fortaleza-CE in the Northeast region, with young people aged 15 to 24, linked to schools, civil society, scholars, professionals and/or managers. The locations were selected for convenience, considering the displacement of the team of researchers and supporters who are part of the Brazilian Network for Information Management and Knowledge Translation in Health. The research interviewed 643 young people who evaluated three campaigns, including a poster, a jingle, and a video, selected from 475 analyzed campaigns. The quantitative methodology meets the EducaIndex, and the qualitative methodology meets the workshops that mediate the application of the instrument in the field. The EducaIndex instrument was reliable (Cronbach’s alpha = 0.700), attesting the ability to reproduce results in time and space consistently. As for the workshops, they allowed interaction between researchers and participants, strengthening the importance of protagonism in the campaign evaluation process.
Os hospitais em Portugal no século XIX e na primeira metade do século XX
Authors: Esteves Alexandra
Published: October 2024

Resumo Desde a época moderna, em Portugal, a assistência à doença foi prestada, sobretudo, pelos hospitais, muitos deles criados pelas Misericórdias. No entanto, a criação de novos hospitais no século XIX e nas primeiras décadas do século XX não trouxe, necessariamente, uma melhoria no tratamento dos doentes, visto que, salvo raras exceções, eram espaços pequenos, mal equipados e carentes de recursos humanos e materiais. O objetivo deste texto é apresentar uma reflexão sobre a resposta hospitalar em Portugal entre 1834 e as primeiras décadas do século XX. Pretendemos apontar as mudanças e continuidades que, nesse período, ocorreram no campo da assistência à doença, fazendo referência à criação de diversas instituições.

Authors: Vitoriano Braga Gabriel , Cremasco Receputi Caian , Jordana da Silva Moreira Eliani , Vogel Marcos , Brito Rezende Daisy
Published: October 2024

O estudo refere-se a uma Revisão Sistemática de Literatura (RSL) nos bancos de dados Portal Periódico CAPES e SciELO, englobando artigos científicos empíricos no idioma português, publicados entre os anos de 2012 e 2022. Três portfólios foram criados: o de busca inicial, adotando os descritores “profissionalidade”, “profissionalidade docente” e “ensino”; ii) o de seleção inicial, com base na leitura de título, resumo e palavras-chave; e iii) o de seleção final, por meio de uma leitura na íntegra, culminando em um corpus de análise de 10 trabalhos. O objetivo desta RSL era identificar elementos que têm estruturado a profissionalidade de professores no contexto da Educação Básica, em diferentes níveis educacionais (Ensino Infantil, Ensino Fundamental e Ensino Médio). A análise do corpus textual foi realizada inspirando-se nos pressupostos da Análise de Conteúdo, de Laurence Bardin, emergindo eixos e subeixos temáticos. Da análise dos cinco eixos temáticos, destacam-se Tensões, dilemas e desafios (80%), Formação Contínua (70%) e Relação (sócio)afetiva e emocional (70%) no corpus de artigos analisados. A discussão dos elementos identificados mostra que a construção da profissionalidade docente perpassa por contradições que afetam a profissão. As estratégias de enfrentamento dos conflitos em diferentes contextos e níveis educacionais envolvem aspectos como o reconhecimento do anseio por uma formação contínua, que facilite a construção de relações interpessoais (com os alunos e com a comunidade escolar) e que, simbolicamente, concretize uma agenda de responsabilidades e valores para com a docência. Finalmente, a análise permitiu a proposta de uma redefinição acerca da terminologia “profissionalidade docente”.
Molecular Docking: An Emerging Tool for Target-Based Cancer Therapy
Authors: Uppathi Pavithra , Rajakumari Suraj , Saritha Kallimakula Venkareddy
Published: October 2024

Molecular docking is a structure-based computational technique that plays a major role in drug discovery. Molecular docking enhances the efficacy of determining the metabolic interaction between two molecules, i.e., the small molecule (ligand) and the target molecule (protein), to find the best orientation of a ligand to its target molecule with minimal free energy in forming a stable complex. By stimulating drug-target interactions, docking helps identify small molecules that might inhibit cancer-promoting proteins, aiding in the development of novel targeted therapies. Molecular docking enables researchers to screen vast reorganization, identifying potential anti-cancer drugs with enhanced specificity and reduced toxicity. The growing importance of molecular docking underscores its potential to revolutionize cancer treatment by accelerating the identification of novel drugs and improving clinical outcomes. As a wide approach, this computational drug design technique can be considered more effective and timesaving than other cancer treatment methods. In this review, we showcase brief information on the role of molecular docking and its importance in cancer research for drug discovery and target identification. Therefore, in recent years, it can be concluded that molecular docking can be scrutinized as one of the novel strategies at the leading edge of cancer-targeting drug discovery.
BS Johnson and the Attack of the White-Collar Working Class
Authors: Ron Matti
Published: October 2024

The twenty-first century has seen a much-deserved revival in interest in BS Johnson as a figure within Britain’s postwar avant-garde, often noted both for his working-class background and vociferous—even dogmatic—espousal of aesthetic innovation. However, while Johnson is often understood as both working class and a writer—not to mention a passionate socialist—he is rarely considered a “working-class writer”, part of the working-class literary canon in the same way as, for instance, Robert Tressell or Alan Sillitoe. This is due in significant part to issues of aesthetics and motifs: firstly, that working-class writing has conventionally been thought of as, by definition, a realist endeavour and so, owing to his avant-gardism, Johnson falls outside of that definition. The second reason is that Johnson’s protagonists are often white-collar workers, rather than the manual labourers commonly associated with working-class fiction. As such, Johnson’s novels are often read as reflecting his philosophical or aesthetic interests, rather than explicitly class concerns (the slight exception being 1973’s Christie Malry’s Own Double-Entry, itself still largely coded as a “political” rather than “class” novel). Yet these class concerns—particularly around the theme of alienated labour—are present in a number of Johnson’s novels, from Albert Angelo (1963) to The Unfortunates (1969), his infamous “book-in-a-box”. As French ultra-leftist, Gilles Dauvé, writes, ‘If one identifies proletarian with factory worker [...] one misses what is subversive in the proletarian condition.’ Johnson’s novels can therefore be read as radical reappraisals of the subversiveness of just that condition.
Reflections on administrative discretion
Authors:   Moscow State Law University named after O.E. Kutafin, Starostin Sergey A.
Published: October 2024

The article is a continuation of the discussion started in 2022 in the journal "Siberian Legal Review" and it presents some other considerations on administrative discretion, based on both a wide theoretical and factual material, and on the rich law enforcement experience of the author. Various scientific approaches to understanding the essence and content of administrative discretion, modern features of its practical implementation, key doctrinal and legislative problems are analysed. In conclusion, the author's definition of administrative discretion, determination of its place in the system of public law is offered. The purpose of this article is to develop and deepen the discussion on the problem - the problem of administrative discretion, discretion - which is topical for the Russian administrative-legal theory and legal practice. During its preparation, the vector of discussion changed several times in the direction of revealing the correlation, interrelation, correlation of administrative discretion, necessity and possibility of evaluation of scientific activity, and scientometrics. The task was complicated by the fact that it was necessary to link scientometrics and administrative discretion in any reasonable way. As a result of the study, the author came to the following conclusions. The first conclusion: administrative discretion should be understood as the choice by public administration of the option of solving a management issue in the form of adopting an administrative act (normative or individual) in conditions of insufficient certainty of the situation and (or) circumstances about which this administrative act is adopted. The second conclusion: administrative discretion is related not only to administrative law and administrative process, but also to public law in general. In fact, within the framework of administrative discretion is allowed interpretation and application of norms of almost any branch of public law. Another issue is that the subjects of administrative discretion as a general rule are bodies of executive power and their officials. But this is a good thing. These subjects should not be too many, because, as Spinoza said, if everyone had the freedom to interpret public law at his discretion, no state could not exist.

Published: October 2024

Purchases made on online platforms have heavily incorporated artificial intelligence (AI) to shape consumer purchasing behavior. To investigate re-purchase intentions, this study combines AI, social media engagement, conversion rate optimization, brand experience and brand preference. A survey was conducted with a questionnaire sent to 355 people who had at least once purchased or used services offered online from any site associated with aviation. The questionnaire was analyzed using structural equation modeling. Utilizing Amos V.22, the study hypotheses were assessed. The empirical results show that social media engagement, brand experience, brand preference and conversion rate optimization were all impacted by AI. Conversion rate optimization and social media interaction also have an impact on brand preference and experience. Re-purchase intention is influenced by brand preference and brand experience. Additionally, the association between AI and re-purchase intention was mediated by social media engagement, brand experience, conversion rate optimization and brand preference. The study will support airline companies in developing AI and creating more effective branding and marketing campaigns to increase customer intention to re-purchase. This study discovered that the use of AI in marketing significantly improved brand preference, which subsequently affected consumers’ desire to make additional purchases. Furthermore, to improve long-term commercial performance and brand attractiveness, the airline should focus brand-building efforts on AI. Thus, the airline ought to make greater investments in AI and booking service technology, both to draw in new business and to strengthen existing ones.

Published: October 2024

Legal Tech Jurisprudence is not as developed as it was hoped for, compared with other fields of study. As a result, legal tech has not advanced globally as would have been preferred and remains primal in nature. The situation is more disappointing when it comes to developing or underdeveloped countries. While tech is critical in countries like India, which is going through digital transition currently, the justice system is still functioning in centenarian ways. For some reason, the system has not yet begun to fully harness the potential of modern IT technologies, which may consist of AI, ML, DL, NLP, etc. but not limited to these technologies. A lawyer, who is an integral part of the justice system, still continues to handle most tasks manually or with the help of an assistant, which often becomes challenging and cumbersome while dealing with complex legal issues that involve humongous contracts, for example. It is problems like these that can be very well handled with the help of technologies, being dubbed as legal informatics (LI), to help elevate the quality and quantity of lawyering and the core of jurisprudence. To try and resolve this problem and find an amicable solution to an extent, we have designed and developed an LI-enabled and proposedly cloud-based innovative computational system, called eLegalls and to be delivered as eLegalls-as-as-Service, and this paper illuminates and elaborates its potential in providing the hassle-free lawyering in digital age.

This paper studies the effects of plate stiffeners on the ultimate load of square concrete-filled double-skin tubular (CFDST) short columns under axial compression. The study determines and compares the load-bearing capacity of concrete-filled steel tubular (CFST) short column, CFDST short column and CFDST short columns with plate stiffeners. To achieve these objectives, the researchers performed experimental tests on six composite column specimens: one CFST short column, one CFDST short column and four CFDST short columns with plate stiffeners. The stiffeners are welded to the inner surface of the external tube through pre-drilled holes systematically spaced at four spacings of 10t, 20t, 30t, and 40t, with t represents the external tube thickness. The test results show that the internal steel tubes increased the ultimate strength of the CFDST short columns by approximately 11% compared with the CFST short columns. The CFDST short column with plate stiffeners showed a significant strength improvement of 33% - 42% relative to the CFDST short column. The ultimate strength of CFDST short columns with plate stiffeners increased with smaller intermittent weld spacing of plate stiffeners. Finally, this study proposes a design model that can accurately predict the ultimate strength of CFDST short columns with plate stiffeners with a predicted to experimental strength ratio of 1.02.

The onset of the Northeast Monsoon (NEM) in Malaysia, as defined by The Malaysian Meteorological Department (MET Malaysia), relies on the sustained easterly wind component for at least seven days, with at least one day featuring a speed greater than 5 knots (2.5m/s). While meteorological parameters have historically been crucial in predicting these kinds of events, new research, like that carried out in Kerala, India, has demonstrated the potential to use nontraditional indicators, such as the concentration of the cosmogenic radionuclide Beryllium-7 (7Be) in the north and south hemispheres for monsoon prediction. This article zooms in on a fundamental aspect of monsoon forecasting: raw data preprocessing. It looks into using R statistical tools to refine and recalibrate datasets using this recently introduced parameter, 7Be, for NEM forecasting focusing on Malaysia. By meticulously adjusting and cleansing raw data, this preprocessing stage aims to align the data with the specific requirements of NEM prediction models, thus enhancing their accuracy and reliability. The significance of robust data preprocessing cannot be overstated, particularly in the context of NEM forecasting, where the accuracy of predictions holds profound implications for various sectors such as agriculture, tourism, and infrastructure planning. Potential biases, anomalies, and inconsistencies in the data can be eliminated with careful preparation, resulting in more reliable projections and well-informed decision-making. As such, this article underscores the critical role of data preprocessing in laying the groundwork for reliable and actionable NEM forecasts, ultimately contributing to the resilience and adaptability of Malaysia’s socio-economic landscape.

Efficient management of food stored in conventional refrigerators poses notable challenges, primarily due to the lack of advanced features required for inventory tracking. The absence of timely alerts further complicates users’ efforts to monitor their food supplies, resulting in understocking, overbuying, spoilage, and wastage. To tackle these challenges, this work proposes a computer vision-based approach to track food items, implementing an intelligent inventory management system for IoT refrigerators. The goal is to reduce food wastage and enhance foodstocking efficiency. A YOLOv4 object detection model was trained on a custom dataset featuring common food items in Malaysian households. The model achieved a 0.8041 average loss, 100% mAP, and 86% average IoU during training. The trained model was subsequently deployed on a low-power single-board computer, implementing an autonomous and real-time inventory tracking system for IoT refrigerators. The system exhibited 93% accuracy, and macroaverage scores of 0.94 for precision, 0.93 for true positive rate (TPR), 0.01 for false positive rate (FPR), 0.93 for F1 score, and 0.99 for true negative rate (TNR). Crucially, the system recognized low-stock events and sent alerts to users through the Telegram instant messaging platform, facilitating just-in-time restocking. This intelligent inventory management system offers a practical solution to address the limitations of conventional refrigeration systems and represents a transformative step towards sustainable food consumption.

In the evolving landscape of 5G networks, Device-to-Device (D2D) communication has emerged as a significant technology to offload traffic, enhance user experience, and expand network coverage. While D2D promises seamless connectivity, efficient relay selection remains a challenge, particularly in dynamic communication environments. This paper introduces an intelligent relay selection mechanism that leverages machine learning, specifically Artificial Neural Networks (ANN) with Radial Basis Function Neural Network (RBFNN) approach, to optimize D2D communication in 5G networks. By integrating a threshold-based relay selection and combining with the predictive capabilities of ANN, we aim to improve overall network coverage. Our method dynamically adjusts selection criteria based on real-time network conditions, ensuring optimal relay selection and minimizing communication breakdowns. Initial simulation results reveal that our approach exceeds traditional techniques, showcasing significant improvements in the coverage area, data output, and reduced inactivity. This research shows the way for a more adaptive, intelligent and efficient D2D communication framework in 5G systems.

Sustainable development in the construction sector should be a participant in utilising the waste materials for the betterment of the industry. Turning waste materials into some application can contribute to the attainment and greening of the planet. In addition, research needs to be carried out to encourage the waste materials into useful building materials and economic. An idea of practicing environmental awareness should be adopted as opposed to simply considering the rapid development as the whole project objective. Inclusion of natural fibres in bricks has been proved to enhance strength development. This study investigates the pineapple fibres inclusion on the mechanical properties of masonry bricks. Experiments were conducted on masonry bricks with pineapple fibre percentage of 0, 0.25%, 0.50% and 0.75% to determine the compressive strength and water absorption of the bricks according to ASTM C67-17 Standard (2017). It was found that by incorporating an 0.5% of pineapple fibres into masonry bricks, the strength properties of the bricks were significantly improved. As a result, this research paper recommends using 0.5% of pineapple f ibre as an optimal fibre content in masonry bricks reinforced with pineapple leaf fibre in the application in construction industry.

The local scour at the triangular nose pier of the Al Kufa bridge, Kufa, Iraq was experimentally investigated using a pier model with a scale of 1:155. Special arrangements were followed to fix the pier model in the middle of the mobile bed with nonuniform sediments of median diameter, d50 =0.30 mm and geometric standard deviation, σg =2.78. The mobile bed had a depth of 100 mm and a length of 2m and was located 6 m from the inlet of a glass-sided titling flume. For five different discharges, the effect of flow parameters (velocity, u, water depth, y and Froude number, Fr), pier dimensions (pier width, b and pier length, l), bed sediment characteristics (d50, σg and threshold velocity for sediments, ut ) and time, t on local scour depth were studied. Throughout the experiments, clear water scour and lived bed scour were achieved. For clear water conditions, the relationship between normalized scour depth (ds /b) and velocity ratio was found almost linear up to ua /ut =1 while for live bed scour conditions, a nonlinear relationship with a decreasing trend was found. For the thin pier, the laboratory data obtained from the present study demonstrated that the depth of the local scour (ds) was independent of the water depth. When Fr=0.061 in both model and prototype, the measured scour depth at the pier model was overestimated by 0.4 m at the pier of Al Kufa Bridge. In addition, a relationship between scour depth ratio (ds /dseq ) and time ratio (t/tseq ) was prepared from laboratory data. The relationship is useful in determining the equilibrium scour depth at the Al Kufa Bridge. Furthermore, the angle of the scour holes (θ) resulted from the equilibrium scour depth was measured and found to be ranges between 14o and 18.4

The advancement of thermoplastic composites reinforced with hybrid kenaf/glass fibres has rapidly progressed, positioning them as viable structural materials for diverse industries. The incorporation of hybrid kenaf/ glass fibres in these composites aims to introduce new dimensions of sustainability. This is driven by the superior strength, stiffness, and lightweight properties exhibited by the hybrid composites, making them well-suited for high-end structural applications. Furthermore, the hybrid kenaf/glass fibres composites offer economic advantages and various benefits, including recyclability, cost-effectiveness, biodegradability, and wide availability. Currently, these emerging composites are gaining attention in industries such as automotive, defence, aerospace, marine, construction, and naval sectors. Despite their increasing popularity, there is a notable gap in the literature, as comprehensive focus on the recent progress of hybrid kenaf/glass fibres reinforced ABS composites for structural applications is lacking. Therefore, this review paper critically discusses recent findings related to the physical, mechanical, and energy absorption properties, as well as processing techniques, of kenaf fibres and their hybrids with ABS matrix materials for aircraft radome. The article also aims to underscore the significance of hybrid kenaf/glass reinforced ABS composites in enhancing mechanical performance for applications requiring radome structures. This review also found out that the composites with quasi-isotropic sequence which combine with ±45-degree fibre orientation provide superior mechanical properties. The ±45-degree stacking is expected to enhance the mechanical properties because it offers balanced in-plane stiffness and strength as well as, improved shear properties. This orientation distributes the stresses more evenly throughout the composite material, leading to improved damage tolerance and impact resistance, which are critical for the structural integrity and durability of aircraft radomes.

The 3D printing has fundamentally transformed the approach to object design and manufacturing, enabling the costeffective production of intricate and customized components. This study aims to investigate the rheological and mechanical properties of Poly-lactic Acid (PLA)/Wollastonite (WA) composite filaments for 3D printing, particularly for bone implant applications. The powder composition used is 90 wt.% PLA and 10 wt.% WA. The blending process was conducted at a temperature of 190°C and a torque value of 30 rpm. Capillary rheometer testing was carried out at temperatures of 160 °C, 170 °C, and 180 °C on the feedstock. The rheological results of the feedstock show pseudoplastic f low behavior, where viscosity decreases with an increase in shear rate. The flow behavior indices obtained at all temperatures are 0.87, 0.79, and 0.49 respectively. At these temperatures, the flow behaviour index is below 1 (n<1), indicating pseudoplastic flow and compatible for the FDM process. The optimal filament extrusion parameters were determined to be 170°C, 190°C, 180°C, and 140°C for the four temperature zones, respectively, with a screw speed of 4.0 rpm and a spool speed of 40 mm/s. The Taguchi Method was employed to evaluate the filament’s quality and strength using three different printing settings. The density of the PLA-WA composite filament was 1.32 g/cm³. These results suggest that the PLA-WA composite has promising candidate use in 3D printing applications.
