Published: January 2025

The emergence of various degenerative diseases caused by highly active and dangerous chemical compounds known as free radicals requires the use of antioxidants to inhibit oxidation reactions and prevent cell damage by binding free radicals and highly reactive molecules. Breadfruit (Artocarpus altilis) leaves are rich in phytochemical secondary metabolites. This study aimed to determine the antioxidant activity and correlate the functional group obtained by infrared profile in the hexane, ethyl acetate, and ethanol extracts of breadfruit leaves with variations in solvent polarity. This study was conducted using an experimental method using breadfruit (Artocarpus altilis) leaves as test materials. The extract was obtained by the maceration method with variations of solvent polarity, namely hexane, ethyl acetate, and ethanol. The examination of antioxidant activity by Diphenyl Picrylhydrazyl (DPPH) method to determine the Inhibitory Concentration 50% (IC50) values and determination of functional groups using the Fourier Transform Infrared (FTIR) method. The antioxidant activity is indicated by Inhibitory Concentration of 50% (IC50) of hexane, ethyl acetate, and ethanol extracts of breadfruit leaves, respectively 139.24 µg/mL (moderate), 47.26 µg/mL (very strong), and 129.31 µg/mL (moderate). The functional group obtained for hexane extract were C–H, C=O, C=C, C– O; for ethyl acetate extract were O–H, C–H, C=O, C=C, C–O; and for ethanol extract were O–H, C–H, C=O, C=C, C–O.

Published: January 2025

This study investigated the effects of market risk on the financial performance of 47 food and beverage companies listed on the Vietnam Stock Exchange, including the Ho Chi Minh City Stock Exchange (HOSE) and the Hanoi Stock Exchange (HNX), over the period of 2008-2022. Forty-seven companies were selected based on industry classification criteria and relevance in the research period. The return on assets, return on equity, and net profit margin were used to represent the financial performance, and the gearing ratio, book-to-market ratio, and financial leverage as the market risk factors. This research used the OLS model, fixed effect model (FEM), and random effect model (REM) for the panel data. The results showed that the impact of the variables was different in the different models. The book to market ratio and gearing ratio had significant negative influences on the companies’ financial performance while the degree of financial leverage and inflation rate showed positive consequences due to the moderate level of inflation in Vietnam over the period of 2008-2022. Usually, the cash ratio and company size showed a proportional relationship to financial performance, while the ratio of debt to revenue and debt to assets had an inverse relationship, meaning an increase will make the business efficiency decrease. Based on the research results, this study provided some recommendations to improve food and beverage companies’ financial performance, and also provided some information for broader research for non-financial companies listed on the Vietnam Stock Exchange.
Analytical incursions into the first work in section I of the vocal-chamber cycle “Ponti Euxini Clepsydra, Sketches in ink wash painting” for oboe, clarinet, soprano, harp and percussion – “Omnia sunt hominum tenui pedentia filo” by Felicia DONCEANU
Authors: Ionescu Madalina Gabriela
Published: January 2025

The love for playfulness, poetry and theatre marked the entire creation of the composer Felicia Donceanu, who tried, through minimal means of achievement, to extract the essence of artistic expression, which any performer or listener could enjoy. The intrinsic link between the two artistic components – the poetic text and the musical text, generated an original compositional style, placed far from the atonal and athematic avant-garde, embracing a modal-chromatic language, sometimes of a romantic nature, at other times with folkloric elements, with neoclassical features, impressionist or expressionist. The ingenuity and diversity of the expressive methods used place Felicia Donceanu in a timeless setting, devoid of a deliberate stylistic affiliation.
The correlation between mechanical properties and electric current under thermal shock for YBa2Cu3Ox superconductors
Authors: Yokobori A. Toshimitsu , Kobayashi Tsukasa , Hashimoto Keizo , Salama Kamel
Published: January 2025

High temperature YBa2Cu3Ox (123, YBCO) superconductors have been shown to possess high current carrying capability which is confined to currents flowing along the strongly super‐conducting a–b planes within a single oriented domain. Usually, in this material, thermal cycling occurs in the temperature region ranging from −196°C (liquid nitrogen) under actual operation to room temperature under out of operation for maintenance. Micro‐cracks are considered to initiate during these thermal cycles which result in the high electric resistance. Therefore, the existence of micro‐cracks is considered to be a dominant factor in decreasing Jc. In this study, an apparatus for thermal cycling has been designed and built to provide thermal cycles ranging from −196°C to room temperature. To clarify the time sequential deterioration on the mechanical properties of YBCO due to thermal cycles, a sharp notched RCT specimen with 20° of notch tip angle and 0.02 mm of notch tip radius was designed. By using this specimen, the time sequential deterioration of stiffness, dP/dδ and fracture toughness of YBCO for a sharp notched RCT specimen due to thermal cycles were investigated. The results show a correlation between these mechanical properties and previously obtained the super‐conducting properties of this material. Thermal cycling causes the deterioration of mechanical properties which results in the deterioration of critical current density.
Theoretical representation of a characteristic curved surface for the life of fracture under the condition of high temperature creep and fatigue interaction based on non‐equilibrium science
Authors: Yokobori A. Toshimitsu , Akaishi Ken , Sugiura Ryuji , Kobayashi Daisuke
Published: January 2025

In this paper, to derive the characteristics of the load frequency of fracture life under the conditions of creep, fatigue and creep‐fatigue interaction and multiplication, a theoretical three‐dimensional curved surface which represents the transition characteristic from the cyclic dependent mechanism to the time dependent mechanism of fracture life is considered as a phenomenon of phase change. This analysis was conducted based on the concept of non‐equilibrium science. That is, a function F was defined as a catastrophic function. The analysis of its stable and unstable state was conducted which characterizes the transition behaviors from the cyclic dependent mechanism to the time dependent mechanism. On the basis of these results, the interactive effect of creep and fatigue on the fracture life was investigated.
The mechanism of hydrogen embrittlement on the basis of the interaction model of dislocations and hydrogen around a crack tip
Authors: Yokobori A.T. , Taketomi S. , Ha J.C. , Shoji T. , Li G.F.
Published: January 2025

Mechanisms of dissolvent anodic chemical reaction and hydrogen embrittlement were proposed as stress corrosion cracking mechanics (SCC). The former is feasible for the case of plastic deformation dominant metals and the latter is for high strength metals such as high strength steels. However, in spite of low yield stress, a discontinuous cleavage‐like fracture is sometimes observed during SCC for ductile fcc alloys. In this paper, we proposed stress corrosion cracking model on the basis of interaction of dislocation and hydrogen around a crack tip to predict discontinuous cleavage‐like fracture during SCC for ductile fcc alloys. Furthermore, we conducted numerical analyses using this proposed model.
Effect of roller‐working and mean stress on fatigue strength of ferritic stainless steel
Authors: Iswanto Priyo Tri , Nishida Shin‐ichi , Hattori Nobusuke
Published: January 2025

This paper covers investigations of the effect of mean stress on fatigue properties of non‐deformed specimens and the effect of roller‐working on fatigue properties of plastically deformed specimens of ferritic stainless steel. In order to evaluate the effect of mean stress on fatigue strength improvement, tensile‐compressive fatigue test have been performed on non‐deformed specimens. In order to study the effect of plastic deformation due to roller‐working on fatigue properties of deformed specimens, rotating bending fatigue test have been done on plastically deformed specimens in several degree of plastic deformation. The results showed that according to increase of the compressive mean stress the fatigue strengths of these specimens increase. Compressive mean stress delays crack initiation and suppresses fatigue crack propagation properties. In case of tensile mean stress, this kind of mean stress decreases the fatigue strength. The fatigue limits of plastically deformed specimen are much higher than that of non‐deformed specimen and do not linearly increase with increase of plastic deformation value. The fatigue limit improvement of deformed specimens would be caused by the compressive residual stress in the notch root and work‐hardening due to roller‐working.
Modeling of dynamic fragmentation in brittle solids
Authors: Gommerstadt B.Y. , Chudnovsky Alexander
Published: January 2025

Several analytical and numerical models of dynamic fragmentation as well as some experimental data are reviewed in this paper. Among others, two of the models previously proposed by the authors of this work are also revisited. One of our models, which based on Fracture Mechanics, is further developed. It leads to a refined fragmentation model that unifies the Griffith and Grady approaches, i.e. at low strain rate it resembles the Griffith condition for brittle fracture, whereas the Grady type relationship obtained for fragmentation is recovered at extremely high strain rate. An important relationship between the two approaches, based one on Fracture Mechanics and another on energy balance is also established. Comparisons of the proposed model with other models and pertinent experimental data as well as with the available results of computer simulations are presented. The present model shows a good agreement with experimental data, when fragmentation propagation velocity is selected in a reasonable range.
Effect of fluid compressibility and borehole on the initiation and propagation of a tranverse hydraulic fracture
Authors: Lhomme Tanguy , Detournay Emmanuel , Jeffrey Robert G.
Published: January 2025

This paper is concerned with the problem of a radial penny-shaped hydraulic fracture transverse to a borehole. Compressibility and borehole radius effects are considered as possible candidates to explain the early unstable phase of the fracture growth observed during laboratory experiments conducted with low viscosity fluids. The fracture grows in an impermeable elastic material under conditions where it can be assumed that the fluid is inviscid. The pressure gradient along the fracture is, therefore, zero. A solution is proposed in terms of dimensionless fluid pressure, fracture radius and inlet opening. It is shown that the problem depends only on a dimensionless time τ and on a dimensionless borehole radius α. With time, the solution evolves between two asymptotic regimes where the solution is self-similar. Compressibility effects control the solution at small time while the solution at large time is dominated by material toughness. A built-in instability is identified in the system of equations describing the problem and a criterion is proposed to predict the occurrence of an unstable growth step after fracture breakdown. The potential for unstable growth depends on the initial flaw length, the fluid compressibility, the volume of fluid and the material elastic modulus.
A criterion study for non-singular stress concentrations with size effect
Authors: Li J. , Zhang X.B.
Published: January 2025

In engineering applications, dealing with the stress concentrations is an important issue. When a stress concentration presents a non-singular feature, the commonly used engineering strength criteria are usually not appropriate to predict the structure failure. In this paper, we first presented a simple experimentation, which consists of a central-holed plate under uniaxial tensile loading. Then we showed that most of commonly used criteria are not suitable for this case of non-singular stress concentration. By analysing the energy dissipation of micro-crack bands under different stress concentrations, we proposed a new fracture criterion based on the finite fracture mechanics. It was shown that this criterion could provide accurate critical remote loads comparing with experimental data. We believe that the three-parameter concept is physically reasonable and can be used in establishing fracture criteria in both the cases of singular and non-singular stress concentrations.
Creep behavior of a directionally solidified nickel based superalloy
Authors: Ibañez Alejandro R. , Saxena Ashok , Kang JiDong
Published: January 2025

Directionally solidified nickel-base superalloys provide significant improvements relative to the limitations inherent to equiaxed materials in the areas of creep resistance, oxidation, and low and high cycle fatigue resistance. The objectives of this study are to perform critical experiments and investigate the high temperature creep deformation, creep rupture and creep crack growth behavior of DS GTD111. The specimens in the longitudinal direction showed higher creep ductility, lower minimum strain rates and longer creep rupture times than the specimens in the transverse direction. The results in the transverse direction were similar to the ones for the equiaxed version of this superalloy A power-law model and the theta-projection model is evaluated for representing the material behavior and both appear to provide accurate representations of creep deformation over a wide range of stress, time and temperature conditions. The Monkman–Grant relationship, the Larson–Miller parameter and the theta projection model have been successfully used to predict the time to rupture for different orientation-temperature-stress conditions. The time dependent fracture mechanics approach is used to model creep crack growth behavior.
Singular stress fields and instability conditions for mode-II and mixed-mode loaded cracks
Authors: Kalthoff J.F. , Fernández-Canteli A. , Blázquez A. , Fernández-Zúñiga D.
Published: January 2025

The stress fields at initiation of a kinked (daughter) crack starting from a (mother) crack subjected to mode-II loading conditions and the influence of these stress fields on the instability condition are investigated. Often the stress distribution along the prospective propagation direction of the daughter crack (before it is actually formed), is considered to be the actual driving force for the crack formation. Emphasis is given in this paper to the changes the stress fields experience in the transition phase from before to after the kinked crack is initiated; in addition, the situation is studied for growing lengths of the daughter crack. It is found that the stress distribution along the prospective path of the daughter crack represents a pseudo-mode-I stress distribution. Numerical calculations using the BEM are performed, proving that a singular stress field according to the regular mode-I loading condition results, showing both radial and circumferential stress singularities, as soon as the daughter crack is formed. The validity of the numerical data is confirmed by experimental results using experimental techniques. These different stress characteristics and their consequences are discussed with the aim of finding an appropriate model for describing realistically the instability process of mode-II loaded cracks.

Published: January 2025

The current study examines how the Provincial Disaster Management Authority (PDMA) used collaborative governance to manage crises. It also aims to identify the elements of cooperative governance, fundamental tactics, and challenges encountered during crisis management. For data collection, semi-structured interviews were used. Twelve interviews with the PDMA top management were conducted and data was transcribed through thematic analysis. It has been determined that collaborative governance and fundamental and complementary conditions impact crisis management, particularly when building collaborative processes. It has also been discovered that the key prerequisites for developing the collaborative process are leadership activities and face-to-face negotiation. Contrarily, supportive settings entail an initial understanding, trust, and commitment that enhance the collaborative process without endangering crisis management. However, the research findings connect well with existing theories especially in governance frameworks on the importance of interactive dynamics. These perceptions can enlighten future study and pursue the practices in crisis management, mostly in how collaborative governance can influence to improve awareness and resilience in disaster management struggle.

Authors: Mariño Gutiérrez L. , Baquero Mochales M. , Meseguer Peinado M.A.
Published: January 2025

In this work it is presented the Jorge Francisco Tello’s legacy related to pathology, with the establishment of a protocol he developed for the systematization of clinical necropsies. This protocol was applied in the Hospital of Infectious Diseases (Hospital del Rey) from 1925 to 1957 and gave rise to the collection of natural anatomical pieces and their photographs on glass plates, preserved in the Museum of Public Health and Hygiene of the Carlos III Health Institute.
For the cataloging of these collections has been used the information provided in the identification labels of the specimens, the admission and autopsy record books of the hospital. The collection of photographic images of the anatomical pieces is also described.
The systematized results of the macroscopic diagnoses of the anatomical pieces and their corresponding clinical diagnoses are presented.
The legacy that Tello began in 1925 currently constitutes material of great value for research and teaching of infectious pathology in the first half of the 20th century, as well as top-of-the-line biological and microbiological material for comparative genetic studies.
Treatment of beta Thalassemia. Can Thalassemia be cured?
Authors: Villegas Martínez A. , González Fernández A.F. , Ropero Gradilla P. , Martínez Nieto J. , Benavente Cuesta C.
Published: January 2025

Thalassemias are a very heterogeneous group of hereditary diseases characterized by a decreased or absent synthesis of a globin chain.
According to the decreased or absent chain thalassemias are classified into β thalassemia, α thalassemia and other not so frequent types. The β-thalassemia can be a severe transfusion-dependent disease (TDT) requiring periodic scheduled transfusions throughout the patient’s life, as well as less severe forms called intermediate non-transfusion-dependent thalassemia (TNDT) and silent carriers or thalassemic trait, which are asymptomatic.
Transfusion and chelation are the two classic pillars on which the treatment of TDT is based.
The only curative treatment for the disease was allogeneic transplantation of hematopoietic progenitors, but this is not a therapeutic option for many patients, due to the limitation of finding HLA-identical family donors.
We now have a new advanced therapy drug, gene-editing, processed “ex -vivo” in the laboratory, using the CRISPR-Cas 9 technique, which has been approved by the FDA and EMA regulatory agencies for the treatment of TDT. Casgevy it is indicated for patients with TDT, aged 12 years and older, who are candidates for allogeneic transplantation of hematopoietic progenitors but are unable to undergo it due to the lack of an HLA-identical family donor.
In this article, we will discuss in more detail this new therapeutic option conditionally approved for patients with TDT that it is postulated as a treatment with potential curative action of the disease.
Saúde mental e psicanálise: uma aproximação por meio da teoria do pensar de Wilfred R. Bion
Authors:   Escola de Enfermagem de Ribeirão Preto da Universidade de São Paulo, Ferrari Camila , Scorsolini-Comin Fabio ,   Escola de Enfermagem de Ribeirão Preto da Universidade de São Paulo
Published: January 2025

O objetivo do presente estudo teórico é refletir sobre possíveis caminhos para a aproximação da psicanálise ao campo da saúde mental e seu fazer, tendo como inspiração a perspectiva bioniana. Nesse diálogo, utilizaremos, como disparadora, a película italiana "Si Può Fare", filme que se passa na época do fechamento de manicômios após a implantação da Lei Basaglia. Nello, o protagonista, permite aos pacientes a criação de formas de expressão dos sentimentos, dando-lhes lugar no mundo. Com isso, encontra-se o movimento de desenvolver a capacidade de pensar do paciente para lidar com as suas frustrações. O lugar do analista, diferente de Nello, estaria em também dar condições de escuta do sofrimento desses sujeitos além das intervenções. Sabendo que estamos vivendo em uma sociedade na qual prevalece o discurso biomédico, que busca categorizar o sofrimento humano com base em nomenclaturas psiquiátricas, a construção de um novo modelo para pensar dentro do campo da saúde mental faz-se necessária e urgente. Com isso, o psicanalista, dentro da instituição, tenta encontrar um lugar em que seja possível trabalhar para além do discurso médico, visando o ser em sua maior complexidade para que ele possa existir de forma humanizada.

Published: January 2025

Introduction: Chronic obstructive pulmonary disease is a growing health problem. It is a chronic
inflammatory lung disorder characterized by progressive, poorly reversible airflow limitation. The
identification of modifiable risk factors for prevention and related patient health education have
given positive results. We have passed from the observation of risk factors to a careful diet rich in
substances capable of improving lung function. The purpose of this integrative review was to
identify, describe and summarize previous studies that have investigated the importance of health
education about nutrition in patients with COPD.
Materials and methods: For this scope, a review process was conducted following these five steps:
1) identification of the research problem, 2) literature research, 3) data evaluation, 4) data analysis
and 5) presentation of the synthesis of the results. After the identification of the research problem,
the second phase of the literature research was conducted using the CINAHL and PubMed
databases. MeSH search terms included: COPD, health education, malnutrition, and Quality of Life.
These terms have been combined each other using boolean operators. The electronic research was
limited to the articles published in the English language within the past 10 years. Studies that
responded to the hypotheses of bibliographic research were considered. Primary studies, systematic
reviews and guidelines were included. Bibliographic research was conducted from 1 June 2024 to
24 October 2024.
Results: Some studies show that by eliminating risk factors, improving nutrition and educating the
patient to self-manage the disease through tertiary prevention programs, there has been an
improvement in the patients’ quality of life.
Conclusion: Correct health education is important to have “instructions” on the pathology and its
self-help management. Outcomes are enhanced by self-efficacy interventions that aim to achieve a
healthy lifestyle through behavior modification, especially about diet.

Published: January 2025

This study investigates the development of energy-harvesting wearable biomedical devices designed to continuously monitor health metrics without the requirement for external power sources. By integrating self-powered sensors that utilize ambient energy, such as body heat and motion, we aim to evaluate the performance and user acceptance of these devices in real-world settings. Our findings indicate that energy-harvesting technologies can effectively support continuous health monitoring, enhancing the practicality and longevity of wearable devices. The pursuit of alternative energy sources has generated considerable interest in energy harvesting devices, which offer sustainable and autonomous power production. These technologies transform ambient energy from the human body or the environment into electrical power, thereby diminishing or potentially removing dependence on conventional batteries. This technology can offer a continuous along with reliable power source by utilizing ambient energy, that includes body heat, chemical energy from body fluids, mechanical movements, as well as light. In addition to improving the user experience by lowering the frequency of recharging, this encourages the creation of wearable devices that are more flexible, lightweight, and comfortable.

Učenici koji su sudjelovali u istraživačkom projektu uključeni su u program GLOBE i informatičku skupinu. Na početku je pomoću aplikacije GLOBE Observer izmjerena visina i određene su lokacije svih stabala te im je izmjeren opseg. Za svako je stablo: izračunata starost, prsni promjer, svježa i suha biomasa, masa pohranjenog ugljika te masa apsorbiranog CO2 . Izračuni su napravljeni programiranjem u Pithonu. Potvrđeno je da količina apsorbiranog CO2 eksponencijalno raste sa starošću drveta, zbog čega je važno čuvati stara stabla.. Dnevno su mjereni atmosferski čimbenici na školskoj meteorološkoj postaji (udaljenosti 100 m od aleje) te se uspoređuju s izmjerenim vrijednostima meteostanice Arduino sustava sa senzorom za mjerenje kvalitete zraka određene ukupnom količinom plinova u atmosferi Marmontove aleje. Rezultati su pokazali da je veća količina plinova izmjerena u danima kad je vlažnost zraka bila veća i u danima s oborinama. Veća količina plinova izmjerena je i u vremenskom razdoblju kasne jeseni kad su stabla odbacila sve listove. Učenici su ovim projektom uspješno integrirala znanja biologije, kemije i informatike u tumačenju ekoloških parametara.

Робота присвячена вивченню температури атмосферного повітря як лімітуючого фактора для сезонних ритмів розвитку рослин в умовах кліматичних змін. Збільшення температури, зокрема в Україні та регіоні Львова, впливає на фенологічні цикли рослин, вегетацію, цвітіння і плодоношення. Аналіз середньорічних температур у м. Львів за період 1993-2022 рр. демонструє їх стабільне зростання. Дослідження показує вплив мінливості температури, особливо в зимові та весняні місяці, на розвиток рослин. Теплі зими та ранні весни можуть пришвидшити настання фаз початку цвітіння і вегетації, тоді як аномалії температури літа і осені можуть як скоротити період вегетації рослин, так і подовжити його. Реакція рослин на температурні зміни залежить від регіону їх походження.

This paper is devoted to the study of atmospheric air temperature as a limiting factor for seasonal rhythms of plant development under climate change. The increase in temperature, in particular in Ukraine and the Lviv region, affects the phenological cycles of plants, vegetation, flowering, and fruiting. The analysis of average annual temperatures in Lviv over the period 1993-2022 shows a steady increase. The study shows the impact of temperature variability, especially in the winter and spring months, on plant development. Warm winters and early springs can accelerate the onset of flowering and vegetation, while temperature anomalies in summer and autumn can both shorten and lengthen the growing season. The reaction of plants to temperature changes depends on the region of their origin.
Keywords: global warming, climate change in Ukraine, phenological cycles, plant adaptation.

Desafios e potencialidades dos livros didáticos de matemática: reflexões a partir de um caso de ensino
Authors: Silva Américo Junior Nunes da , Correia Vinícius Christian Pinho
Published: January 2025

Este artigo objetiva analisar os livros didáticos utilizados em uma turma da 2ª série do Ensino Médio de uma Escola Estadual em Senhor do Bonfim-BA, durante a realização de um Estágio Curricular Supervisionado do curso de Licenciatura em Matemática da Universidade do Estado da Bahia, Brasil. O percurso metodológico utilizou como instrumentos para a produção de dados a análise de livros didáticos e a reflexão sobre um caso de ensino, ambos interligados. Busca-se compreender o itinerário reflexivo-analítico constituído a partir do uso de Casos de Ensino, como um elemento importante para o processo de formação inicial de futuros professores de Matemática. O Caso, ao criar narrativas que destacam o protagonismo dos futuros professores, em determinadas situações didáticas, propôs ao estudante estagiário participar e contribuir na análise de um livro didático de Matemática, especificamente o da turma em que se realizava o estágio. Esse processo de análise dos Livros Didáticos, inserido no contexto do Caso de Ensino, revelou-se um movimento reflexivo importante para a formação inicial, principalmente por possibilitar a compreensão dos critérios e mecanismos de escolha dos livros utilizados nas escolas, algo que permitiu entender melhor suas potencialidades para o ensino e a aprendizagem da Matemática. Concluiu-se que muitos livros não contextualizam os conceitos com a realidade do semiárido nordestino, algo que justifica a importância de integrar essa discussão nos cursos de formação, preparando os professores para adaptar o material didático, quando necessário, às suas realidades regionais. Advogamos, portanto, para necessidade, também, de que as editoras considerem essas especificidades regionais ao desenvolver livros didáticos.

Este artigo tem como objetivo explorar metodologias para otimizar o processo de fabricação de luzes automotivas, com foco na análise e aprimoramento de uma linha de produção automatizada. A pesquisa foi realizada por meio de um estudo de caso em uma empresa fornecedora do setor automotivo, com o intuito de identificar as principais ineficiências operacionais e pontos críticos no processo de fabricação. A partir da análise dessas ineficiências, o estudo propõe intervenções específicas que buscam melhorar a utilização dos recursos, reduzir o tempo ocioso das máquinas, corrigir falhas recorrentes no maquinário e aprimorar a integração dos sistemas automatizados. A abordagem adotada para a pesquisa é qualitativa e exploratória, utilizando ferramentas para identificar as causas subjacentes dos problemas operacionais. Através dessa análise, foram propostas ações concretas, como a otimização do tempo de máquina, ajustes no maquinário e melhorias no sistema de automação, com o objetivo de aumentar a eficiência, a produtividade e a qualidade da produção. Os resultados obtidos indicam que as intervenções implementadas geraram ganhos significativos em termos de eficiência operacional, aumento do OEE (Overall Equipment Effectiveness), redução de falhas e melhoria na qualidade do produto final. A pesquisa contribui para a literatura sobre otimização de processos na indústria automotiva, oferecendo insights valiosos sobre como práticas de melhoria contínua podem ser aplicadas para aumentar a competitividade e sustentabilidade das empresas neste setor altamente competitivo.
