A cultura da prática tradicional das marcenarias de Palmeira dos Índios e sua influência na segurança do trabalho
((CENTRO UNIVERSITÁRIO DE MACEIÓ – UNIMA | Afya , 2023-09-17) Cavalcante, Jesimiel Pinheiro; Pereira, Jesana Batista; http://lattes.cnpq.br/2329848572181989; Mendes Junior, Walcler de Lima; http://lattes.cnpq.br/6938727316741941; Junkes, Janaína Accordi; https://orcid.org/0000-0003-2971-9855; http://lattes.cnpq.br/2329848572181989; Pereira, Jesana Batista; http://lattes.cnpq.br/2329848572181989; Marques, Verônica Teixeira Marques; http://lattes.cnpq.br/0156664290521652; Dias, Julliana Michaello Macedo; http://lattes.cnpq.br/8996477208727758
En varias ciudades brasileñas la fabricación de muebles de madera se realiza en talleres de carpintería, que forman parte de la cultura tradicional y popular brasileña. En esta actividad, el uso de diversas máquinas y equipos son constantes y plantean diversos problemas físicos, químicos, biológicos y ergonómicos, siendo los principales agentes: ruidos y vibraciones de las máquinas, polvo de Tableros de Fibra de Media Densidad (MDF), maderas, pinturas y resinas, movimientos Lesiones repetitivas y directas. En Brasil, las estadísticas de accidentes superan los 500.000 accidentes por año, estos a menudo resultan en incapacitación temporal o permanente, además de consecuencias sociales y psicológicas. En varios estudios, los resultados apuntan a una alta tasa de accidentabilidad en la carpintería. A partir de este entendimiento, el objetivo de esta tesis fue comprobar la posible influencia de la cultura en la forma actual de trabajar de los carpinteros en relación a temas de Seguridad y Salud en el Trabajo (SST), con base en entrevistas con 14 carpinteros del municipio de Palmeira dos Ìndios - Alagoas, a través de la aplicación de Cuestionario semiestructurado con preguntas cerradas y abiertas. Se encontró que alrededor del 71 % de los carpinteros aprendieron la práctica tradicional de la carpintería antes de los 18 años, Esto significa que todavía eran menores de edad. El 100 % de ellos aprendió a través de carpinteros. más experiencia, es decir, no participaron en cursos profesionales de su área de actividad y el 90 % Aprendí de carpinteros que no usaban regularmente equipos de protección. Individuales (EPI). Se encontró que el 90 % de los carpinteros no usaban regularmente EPI, a pesar de que el 100 %conoce los riesgos y ya ha sufrido algún tipo de accidente, con un 65 % ya ha participado en conferencias o cursos de capacitación con el Servicio Brasileño de Soporte a las Micro y Pequeñas Empresas (SEBRAE) durante su vida profesional. En esta resistencia a uso de EPP existe una fuerte tendencia a ser causado por la cultura de influencia de la forma en que aprendió la profesión, ya que el 80 % de los carpinteros, en sus discursos, afirmaron que no El uso de protección individual, de forma regular, se debe a que aprendieron de las personas. que no utilizaron EPP. De esta manera se llega a un entendimiento de que, incluso participando formación durante su profesión y sensibilización sobre los diversos riesgos inherentes a la SST, Los carpinteros optaron por ignorar los riesgos y no protegerse. Estos resultados refuerzan La tesis de que la cultura, específicamente la forma de aprender, influyó directamente en la toma de decisiones. decisión de los carpinteros de no protegerse en cuestiones de SST, lo que lleva a un cierto Banalización de los riesgos que se traduce en un elevado índice de accidentes.

The absence of actions to manage information in the operational sphere (on the shop floor) affects the communication quality in this sector. Communication problems, in turn, can negatively impact operational security and organizational culture. Thus, this study proposed a model to analyze communication in the operational sector using the Structural Equation Modeling (SEM) technique. A mathematical model was presented, consisting of 1 exogenous latent variable, knowledge management, and 4 endogenous variables: (i) oral communication; (ii) written communication; (iii) Man interaction with information and communication technologies (ICTs); and (iv) the operational communication. The case study was carried out in a land-based oil production region in the Northeast of Brazil where data were collected through a structured questionnaire with a Likert scale response. After analysis using the SEM, and using the same database, a supplementary study was carried out based on the development of a neuro- fuzzy model to assess information management in the operational sector. The SEM confirmed 6 of the 9 hypotheses proposed in the theoretical model. The results obtained showed that operational communication is directly influenced by knowledge management and by man interaction with ICTs. Written communication and oral communication had a direct influence on man interaction with ICTs and had an indirect influence on operational communication, thus, communication on the shop floor occurs predominantly through technologies. Knowledge management had a direct influence on the 4 endogenous variables, with strong explanatory and predictive relevance effects. The result of the neuro-fuzzy model showed that information management on the shop floor improves as actions are taken to acquire, store and distribute information about the operational routine. The model presented relevant contributions to the refinement of theory and practical contributions to support information management on the shop floor.
Avaliação da atividade e da inibição de ureases: estudos biofísicos de interação e desenvolvimento de metodologias analíticas
(2022-12-19) Tavares, Maria Celia; Santos, Josué Carinhanha Caldas; http://lattes.cnpq.br/3735618604163061; Carrilho, Emanuel; http://lattes.cnpq.br/9157872297410868; Santana, Rodolfo de Melo Magalhães; http://lattes.cnpq.br/2427465793815991; Cunha, Silvio do Desterro; http://lattes.cnpq.br/5661286013847300; Goulart, Marilia Oliveira Fonseca; http://lattes.cnpq.br/5271094336884473
Urease catalyzes the hydrolysis of urea in NH3(g) and CO2(g); it is associated with problems in agriculture, such as reduced efficiency of urea fertilizer, and health, because it provides a microenvironment favorable to the colonization of the human stomach by H. pylori bacteria. Therefore, inhibiting and determining urease activity in different matrices is important. Thus, the main objective is to evaluate the mechanism of urease inhibition by organic compounds (natural and synthetic) using biophysical studies, as well as the development of methodologies to determine the activity of ureases in soils and saliva (synthetic and human), in addition to evaluating potential inhibitors. For the interaction between urease and natural isothiocyanate (MFC), an IC50 = 487 µM was obtained, and the compound was classified as a mixed inhibitor. The synchronized fluorescence assays corroborated the nature of the inhibition process. Spectroscopic studies indicated conformational changes in the enzyme resulting from the MFCurease interaction, with a binding constant (Kb) equal to 1.80 × 102 L mol-1 and stoichiometry 1: 1. In addition, the formation of the corresponding dithiocarbamates and thioureas has been proven after the reaction of the MFC with amino acids containing thiol and amine/guanidine groups. Thus, the urease's inhibition mechanism by MFC occurred through covalent and noncovalent interactions. MFC was more effective in soil microbiota than in vitro, with inhibition equivalent to NBPT for the two soils evaluated. For the interaction of urease with five benzoylthioureas, a direct relationship was found with the size of the N-alkyl substituent with the IC50 (M) and Kb values. It was found that BTU1 was the most active and, therefore, selected for biophysical studies in soils with urease. For the BTU1-urease complex, Kb was on the order of 103 L mol-1 at the different temperatures evaluated; based on thermodynamic studies, the preferred forces for stabilizing the supramolecular complex were hydrogen bonds and van der Waal forces. Synchronized fluorescence and competition assay studies indicate that BTU1 probably has classic mixed inhibitor behavior. In the different soils evaluated, BTU1 showed an inhibition potential equivalent to NBPT, emphasizing the importance of in vitro assays and application in a real sample for selecting a potential inhibitor. Two analytical paper devices (UrePAD and Multicolor PAD) were developed to determine urease activity in soils, saliva, and in the absence/presence of inhibitors. UrePAD is based on the color change of the acid-base indicator phenol red, exploring the change in pH due to the hydrolysis of urea by urease. The Multicolor PAD is also a colorimetric device employing five acid-base indicators (phenol red, bromothymol blue, bromocresol purple, m-cresol purple, and neutral red) and surface-modified polyelectrolyte poly-4-styrene sulfonate paper. sodium or polyvinylpyrrolidone. The images obtained were digitalized in a bench scanner, and the analysis was performed in the Corel Draw X8 software. The methods showed a mean LOD of 0.10 U mL-1 with linearity between 0.25 and 4.0 U mL-1. Both devices were applied to determine urease activity in four soil samples with different characteristics and in vitro evaluation of classic inhibitors. The results obtained did not differ statistically (95% confidence) from the reference method of indophenol blue, having as advantages the low cost, reduced volume of reagents/sample combined with simplicity and portability, showing the ability to simplify the determination of the activity of the urease in soils and the evaluation of potential inhibitors. Finally, the Multicolor PAD was applied to determine urease in a sample of synthetic and human saliva, with quantitative recoveries (between 80 - 120%) and to show a more significant variation in color intensity for a human saliva sample from an individual infected with H. pylori. Thus, it is possible to use a simple, fast, low-cost method to diagnose infection by ureolytic bacteria such as H. pylori.

In recent years, the field of soundscape studies has gained increasing prominence, driven by the need to transcend traditional approaches to urban environmental management that focus exclusively on noise control policies. Adopting a multidisciplinary perspective, the assessment of urban sound environments integrates both subjective variables, related to user perception and objective physical parameters inherent to the specific context and location. In this regard, the development of analytical tools capable of understanding and predicting perceptual responses to planning decisions through predictive modeling is essential. This doctoral thesis proposes a methodology for the evaluation of urban soundscapes based on the development of predictive models and their application in public spaces in the city of Maceió, Alagoas, Brazil, specifically along the seafront of the Ponta Verde and Pajuçara neighborhoods. The study adopts an applied research design, encompassing field data collection in accordance with the ISO 12913 normative series, including soundwalks, questionnaires, and acoustic measurements. A novel methodological approach is presented, involving the construction of a mixed questionnaire grounded in methods A and B of ISO/TS 12913-2, enriched with contextual and visual information. Furthermore, a procedure for acoustic environment characterization is proposed, aligned with ISO/TS 12913-3, and complemented by in-depth analyses of interrelations among perceptual and contextual factors. This is followed by correlation analyses and the identification of relevant indicators (empirical data) and descriptors (measures of perceptual response) for model development. The modeling framework comprises both linear predictive models (multiple linear regression) and nonlinear models (artificial neural networks – ANN). The ANN-based models demonstrated up to 35% greater predictive performance compared to linear models, with one model achieving a coefficient of determination (R²) of 0.98. The methodological advancements presented herein offer a significant contribution to the technological field of urban soundscape assessment, providing support for evidence-based decision-making by researchers and urban planners. This research expands the theoretical and practical horizons of soundscape studies by proposing innovative approaches for the characterization and predictive modeling of urban acoustic environments.
Dificuldades associadas ao sedentarismo em adolescentes ingressantes no ensino técnico médio integrado do Instituto Federal de Educação Tecnológica de Alagoas em 2024
(UNIVERSIDADE TECNOLÓGICA INTERCONTINENTAL / UTIC , 2025-07-29) Araújo, José Roberto Alves; Montiel, Aberlardo Juvenal; González, Hugo Ferreira; Chávez, Silvio Torres; Cardozo, Julio César; Mitjans, Patrícia Figueredo de; Fretes, Aníbal Barros
This thesis investigates the challenges associated with sedentary behavior among adolescents aged 15 to 17 who enrolled in the Integrated Technical High School Program in the Building Construction course at the Federal Institute of Alagoas (IFAL) in 2024. Using a quantitative approach, the research analyzes data collected through questionnaires from 40 students with a Body Mass Index (BMI) ≥ 25, across the campuses of Coruripe, Maceió, and Palmeira dos Índios. The results reveal a high prevalence of sedentary behavior, especially among female students, which correlates with inadequate dietary practices and a lack of regular physical activity. The theoretical framework addresses key concepts such as sedentary lifestyle, adolescent health, and the environmental and social factors that influence this behavior. The identified difficulties include the absence of physical activity, poor nutrition, and inadequate school infrastructure. Although students generally perceive physical spaces positively, access to these facilities is limited, and many do not engage in the recommended amount of exercise. The conclusion emphasizes the urgency of institutional strategies to promote health and physical activity, highlighting the role of education as a crucial transformative agent in combating youth sedentarism. The study underscores the importance of integrated and comprehensive interventions that consider both structural and behavioral aspects, aiming to improve adolescents’ quality of life and well-being in the school environment. Such actions are essential for fostering healthy habits and reducing the risks associated with a sedentarylifestyle in youth.
Efeitos das tecnologias de realidade aumentada e virtual como recursos visuoespaciais na aprendizagem de geometria molecular

This research investigated the effects of didactic interventions mediated by augmented reality (AR) and virtual reality (VR) technologies on the learning of molecular geometry concepts. Given the complexity associated with learning molecular structure, this investigation identifies conceptual errors, visuospatial issues, and the use of digital technologies as important elements for developing effective didactic strategies. Utilizing a qualitative and quantitative, applied approach and an explanatory sequential mixed methods data collection and analysis strategy, the research was organized into three complementary studies. The first study aimed to identify conceptual errors related to molecular geometry through a diagnostic test applied to 55 undergraduate biotechnology students at the University of São Paulo. The results revealed difficulties in transitioning between two-dimensional and three-dimensional representations, emphasizing the need for didactic strategies with multiple representations. The second study, conducted with the same participants from study I, assessed the effect of AR on learning molecular geometry. Students were divided into two groups: one reviewed the subject with the support of a conceptual map with static molecules (group A) and the other with a customized conceptual map with AR (group B). The comparison of performance in the task of constructing physical molecules showed superior performance for group B, suggesting that emotional and attention factors may have contributed to a good spatial perception of the molecules. The third study, conducted at the University of Surrey, evaluated the effect of VR, complemented with other resources, on the understanding of molecular geometry. This study highlighted the set of tasks in the pedagogical intervention as engaging, facilitating learning regardless of students' prior knowledge level, and effective in leveling knowledge among different groups. The study conclusions emphasize the relevance of diagnostic tests to identify conceptual errors and the importance of integrating immersive technologies and practical activities in chemistry education. The findings reinforce the need for carefully planned, implemented, and evaluated didactic strategies to enhance performance in chemistry educational contexts.
"Entre Jesus, Apolo e Obatalá”: o hibridismo transcontinental do Vale do Amanhecer e as relações de poder
(2024) Silva, Roberto Calabria Guimarães da; Raimundo, Valdenice José; Peixoto, Adelson Lopes; Santos, James Washington Alves dos; Aragão, Gilbraz de Souza; Campos, Zuleica Dantas Pereira; Raimundo, Valdenice José
This research had as its object of study to analyze the power relations, which at an institutional level, ranging from the command of work to the national/international command of religion, at a spiritual level organizes the hierarchy between men and women, present in the Vale do Amanhecer, through the perception of mediums. In order to respond to the problem presented by the object, the following objective was formulated: to investigate the religious practices of the Vale do Amanhecer, based on the analysis of its history, associating it with the story of Tia Neiva and relating it to transcontinental hybridism. This analysis will have as categories of analysis the transcontinental hybridism and the power relations. The choice for transcontinental hybridism occurred because it was not possible, in our analysis, to dialogue with the syncretism category, since the pantheon of the Valley forms a mosaic with entities from various faiths and continents such as Candomblé, Umbanda, Christianity, Kardecism, religions of Ancient Greece and Egypt, Buddhism and ufology entities as elements of the book Exilados de Capela, involving spiritual entities from religions of four continents that were incorporated into the Vale do Amanhecer, working in order and synchrony, without the mirroring of the entities, as was imposed on religions of African origin, in which an Orixá represented a Saint, as a way for the enslaved to be able to worship their faith without being repressed by their masters. To collect the data, forms with specific questions about the topic were sent, and the responses were analyzed using a quantitative and qualitative approach, in which the percentages, individual analysis, and the combined responses made it possible to understand the mediums' view of how they observe the hierarchy, defined by power relations, in a hybrid and transcontinental community. This research also focused on analyzing the place that women occupy in the hierarchy of the Valley. The research showed that most women perceived a devaluation of the place occupied by the female public, which leads to a contradiction, since the religion was created by Tia Neiva, who after her death was elevated to one of the main spiritual entities of the Vale do Amanhecer. This study will contribute to a better understanding of the relationships that are established in the Valley, as well as give visibility to the religious and spiritual practices experienced in the Vale do Amanhecer. The thesis is based on the dialogue between the categories of hybridism, taking as a basis Cancline (1997), a genre in which Nunes's (1985) thinking fits into the issue of women's protagonism in the Valley, and finally, multiculturalism based on the concepts of Touraine (1997). The thesis proposes to describe the Vale do Amanhecer in its historical context and in its relations with the religions that hybridize with it, emphasizing Catholicism, Kardecism and Umbanda, which exert a strong influence, both in the rituals and in the mediums and patients who attend.
Escolas como organizações que aprendem: a autoavaliação como moduladora da aprendizagem da escola
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-08-26) Moura, Elton Oliveira de; Bispo, Marcelo de Souza; http://lattes.cnpq.br/0046249640629512; Silva, Anielson Barbosa da; http://lattes.cnpq.br/3405428972303042; Guerra, Maria das Graças Gonçalves Vieira; http://lattes.cnpq.br/7195833831322050; Vieira, Almir Martins; http://lattes.cnpq.br/4298642111341453; Brito, Simone Magalhães,; http://lattes.cnpq.br/1833114674355841
This thesis dissertation aimed to analyze how the practice of school self-assessment acts as a modulating element of school learning. The onto-epistemology of the Theories of Practice was adopted from the sociological perspective of Learning Organizations. The argument of this thesis is based on two assumptions: (1) the school is an organization that learns from its daily practices, and (2) that self-assessment can be a way to the development of school learning. The empirical study had a first exploratory phase, where some specialists and professionals in educational management were interviewed to foster reflections on the evaluation and learning processes of the school. In the second moment, empirical research was conducted in a public elementary and high school in the city of João Pessoa (PB) in northeastern Brazil. Data collection was driven through online interviews with participants from the school community, remote observations, and documents. Because the research was conducted during the Covid-19 pandemic, digital technologies such as video conferencing and messaging applications mediated the data collection process. The data analysis process adopted the framework proposed by Bispo (2015) to analyze research based on practice. The study's main results indicate that school learning occurs from three practices: self-assessment learning, engagement in practice, and translating policies and context. In addition, it was possible to verify that selfassessment acts as a modulating element of school learning to the point that it balances the relationship between concept ("what") and instrument ("how"). School self-assessment as a modulator of learning is based on the idea that reflection on the practices allows the school to direct more appropriate actions to its specific needs. This research contributes to approximate fields of Administration and Education to develop an expanded understanding of studies on school management and educational management. Also, in building the development of an alternative approach to the study of Schools as Learning Organizations from social learning. Last, in thinking possibilities of evaluation less classificatory, less focused on accountability, and more focused on school learning.

This thesis analyzes the contributions of the “Espaços 4.0” at the Federal Institute of Alagoas (IFAL) to students' Maker Learning, with a focus on the role of monitors in this innovative educational context. The study investigates how innovative environments that integrate Fourth Industrial Revolution technologies with active methodologies contribute to the teaching-learning process. The central question is: How do IFAL’s Espaços 4.0 contribute to the initial and continuing education of young people through Maker Learning? The research aims to understand the effects of these spaces on student development, highlighting the relationship between Maker practices and the acquisition of skills essential for Society 4.0. The FE Classification (Purpose and Structure) was developed, introducing a new categorization for Brazilian Maker Spaces, along with the TMI-E Model (Think, Make, Improve, Explore), which expands the traditional TMI model (Think, Make, Improve) by including the "Explore" phase. The methodology followed a mixed approach, including a Systematic Literature Review and field research conducted in six IFAL campuses, involving students aged 15 to 29 and the monitors of the Espaço 4.0 project. Data collection was carried out through questionnaires and reports, and analyzed using descriptive and inferential statistics, as well as coding cycles. The results indicate that the Espaços 4.0 foster autonomy, creativity, technical and collaborative skills, as well as critical reflection and continuous exploration. Students showed significant progress in problem-solving and practical engagement, with active support from monitors who played a key role in knowledge mediation and project facilitation. Despite the positive outcomes, challenges related to infrastructure and limited resources were reported, affecting motivation and performance. Gender, racial, and income disparities also highlight the need for more inclusive educational policies. The experience of the Espaços 4.0 demonstrated a significant contribution to communities with limited access to innovation, helping to broaden the democratization of knowledge and reduce social inequalities. It is concluded that IFAL’s Espaços 4.0 plays a transformative role in the education of young people in Alagoas, preparing them for Society 4.0 and helping to reduce educational inequalities. The research offers replicable models for institutions, suggesting future investigations into the long-term impacts of these spaces.
Estratégias de aprendizagem no ensino remoto emergencial do Instituto Federal de Alagoas
(CENTRO UNIVERSITÁRIO DE MACEIÓ – UNIMA | Afya, 2025-09-23) Melo, Helisabety Barros Mendes de; Mendonça, Adriana de Lima; http://lattes.cnpq.br/0381713043828464; Mendes Junior, Walcler de Lima; http://lattes.cnpq.br/6938727316741941; Pereira, Jesana Batista; http://lattes.cnpq.br/2329848572181989; Junkes, Janaína Accordi; http://lattes.cnpq.br/7777461824456062; Santos, Pedro Henrique Simonard; http://lattes.cnpq.br/0615985683640773
Emergency Remote Teaching (ERT) during the COVID-19 pandemic posed significant challenges for education. Students, for instance, had to adapt to the sudden transition to an online environment, and many struggled to maintain focus and manage their studies independently, making it necessary to adopt Learning Strategies. In this context, this research investigates the extent to which students enrolled in technical programs at the Federal Institute of Alagoas (IFAL) - Maceió Campus - made use of any type of Learning Strategy during ERT, aiming to understand how they coped with the demands of this new teaching format. With a qualitative-quantitative approach, a case study methodology was adopted, articulating two main procedures: Content Analysis of the students’ reports submitted as part of formative assessments during ERT, based on Bardin (2016), and the application of the Learning Strategies Assessment Scale for Vocational Education Students (EAVAP-EP) developed by Pereira; Santos; Ferraz (2020). The qualitative analysis of the students' narratives highlighted issues related to infrastructure and technology, teaching methodology, learning difficulties, and mental health—factors that compromised the appropriate use of these strategies. Students’ perceptions also revealed weaknesses in the institutional planning of ERT and gaps in the provision of technological, pedagogical, and psychological support. The EAVAP-EP, a validated instrument composed of 33 items distributed across three dimensions (Cognitive Strategies, Metacognitive Strategies, and Absence of Dysfunctional Metacognitive Strategies), was completed by 189 students. Statistical analysis was performed using R software (version 4.3.3), employing descriptive techniques. Quantitative data revealed satisfactory use of Metacognitive Strategies and, to a lesser extent, Cognitive Strategies. However, some students exhibited behaviors detrimental to learning (Absence of Dysfunctional Metacognitive Strategies). The results reinforce the urgent need, in light of the challenges faced, to implement pedagogical policies that systematically develop Learning Strategies, promote student autonomy, and foster better conditions for coping with adverse educational contexts.

Over the past few decades, research around adaptation and academic success in higher education has increased. A greater number and diversity of students enter this level of education, justifying greater concerns about their academic performance and consequent completion of training. Data collection took place longitudinally at the Instituto Federal de Alagoas-Ifal (Campus Maceió) and included three studies with different samples, between 317 and 420 students from different courses, distributed between degrees or bachelors. At first, even before the pandemic, we applied the questionnaires in person. Subsequently, with the Covid-19 pandemic and the transition of activities to Emergency Remote Teaching (ERE), all the research was done from contacts and the application of online questionnaires. The study considered the following steps: the first took place at the time of enrollment, between the 1st and 3rd week after admission, where students were invited to participate in the study and provide information regarding sociodemographic characteristics; your previous academic career; as well as expectations and anticipated difficulties related to the chosen course. The second stage took place between the 6th and 8th week of classes since the beginning of the course. In this phase, information related to the academic experiences of these students was collected; and inserted questions about the socio-emotional impact of the Covid-19 pandemic. In the third stage, at the end of the school year, the process of adapting students to their courses and their intention to drop out of the course was evaluated. The thesis compiles four articles, including an introduction, a theoretical reference chapter and methodological course and a conclusion. The articles that made up the thesis were: 1- “Academic Adaptation of 1st Year Students: Promoting Success and Permanence at the University”; 2- “Academic Expectations and Difficulties in Higher Education Entrants: Analysis in Function of Gender and Quota System”; 3- “Effects of Remote Learning on Higher Education students”; 4-"Difficulties in the academic adaptation of higher education students in times of a pandemic". The results point to the complexity of the convergence of personal and contextual variables in the process of academic success and school dropout. In this process, the need for public policies to gradually decrease the retention and dropout rates stands out, as well as the design of institutional strategies to support the career development of these students, mainly through integration activities and support services. specialized.

In Alagoas, mining activities have been taking place in the city of Maceió since the 1970s to extract rock salt, a type of sodium chloride used in the manufacture of caustic soda and PVC. In February 2018, after heavy rains and an earthquake, several cracks appeared in streets and properties in the Pinheiro neighborhood. A year later, the same phenomenon was also recorded in the neighborhoods of Mutange, Bebedouro, Bom Parto and Farol, resulting in the expulsion of approximately 60,000 people from the five neighborhoods affected by the overexploitation of rock salt and the closure of more than 6,000 companies. The objective of the research was to analyze the impacts on the businesses of micro and small entrepreneurs affected by the mining disaster in Maceió, Alagoas. In order to analyze the impact of such a disaster on entrepreneurs/traders, the study uses a mixed approach, of the explanatory sequential type. The first phase, quantitative, was characterized as a cross-sectional study, while the second phase was qualitative, exploratory and descriptive in nature. The environmental disaster caused by rock salt mining contributed to losses for micro and small businesses in the affected neighborhoods. In addition to the economic impact, the disaster caused by the subsidence of the soil caused by the Braskem mining company also caused damage to the mental health of micro and small business owners in the region, according to the participants in the survey, which took place between May 2023 and December 2024. Regarding the value of the PCF from the Braskem mining company for business owners: 3% thought the amount of financial compensation paid was fair, while 34% said it was not. The decrease in revenue and financial difficulties led to the closure of numerous companies and the loss of jobs. Dissatisfaction with the social rent paid by the Braskem mining company and the compromised mental health were reported by the majority of business owners. Keywords: Mining, Micro and small businesses, Entrepreneurs/Traders, Maceió.

The present research proposes a reflection on public policies and government programmes aimed at women in Brazil, using as a shortcut the Mulheres Mil Program in the period from 2005 to 2019 and its developments at the Federal Institute of Alagoas. Since the Mulheres Mil Program is a public policy of combating gender inequalities, reducing poverty, raising schooling and reducing violence against women, the design of this study is organized to answer the following question: does the women's mil Program envisage in its formulation commitments with productive inclusion and with the tackling of gender disparity, thus contributing to the full exercise of citizenship of women served? To this end, we systematically and analytically identified the formulations of public policies for women, the advances and challenges of the National Policies Plans for Women, the proposal of the Women's Mill as a social policy of inclusion and gender and the perception of the progress from vocational training and incentive to formal education in the courses offered. Faced with the object of study, the research focused on a qualitative approach using oral history as a method. The life stories of ten graduates who were beneficiaries of the Mulheres Mil Program at the Federal Institute of Alagoas were analyzed. The data collection took place between October 2022 and January 2023 in face-to-face meetings to build their life stories. The narratives were categorized around three axes: the socio-economic profile of the women interviewed, the elevation of the schooling of the graduates after participating in the Program and the insertion of women in the formal labour market according to the vocational training received. The narratives reveal that the exgresses are in the age group between 29 and 61, 70% are married and have between 01 and 06 children. Most (60%) have completed secondary education, but only 10% have continued their studies after participating in the Programme. The analysis on the income of the graduates shows that 50% are engaged in some kind of paid activity. It was also noticed that the beneficiaries were able to put in practice the knowledge acquired in the courses, but were not inserted into the formal labour market. The life stories of the women interviewed revealed that the participation of the Program had positive effects in relation to the rescue of self-esteem, the discovery of their rights and the living with a citizen education. With regard to the increase in schooling, it was found that a significant proportion (90%) of the graduates failed to resume their studies. The results demonstrate the importance of fostering debate on the challenges in formulating and implementing public policies for women.

Automated Guided Vehicles (AGVs) are essential for industry material transportation. In the Industry 4.0 and Industrial Internet of Things scenario, the AGV fleet is expected to be connected and integrated into the factory management system, being flexible and adapting to new demands. AGV control systems with fixed path navigation may not meet these requirements. Edge computing brings cloud resources to the network’s edge, making them closer to users. These resources can be accessed through a wireless network and applied to industrial demands. The AGVs can benefit from this when offloading tasks that require more computing resources to the edge server. However, the wireless network in the industrial environment is subject to degradation due to interference, signal reflections, shadowing effects, and electromagnetic wave absorption, among other challenges. The AGV, as a mobile robot, may traverse areas where the signal is degraded, increasing risks of collisions and accidents. Results of experiments suggest that Model Predictive Control (MPC) executed at the edge server, combined with a delay and packet loss compensation strategy implemented in the robot, can be used to mitigate these network degradations. In sequence, a two-tier architecture with MPCs is proposed to control multiple AGVs. The first tier, executed on the edge server, plans the trajectory of the AGVs globally, preventing collisions of the AGVs with fixed obstacles and each other. In the computer embedded in the AGV, the compensator used in the previous experiments gives place to a trajectory-tracking MPC, which must receive the trajectory of the respective AGV from the edge server and track it. Results of experiments carried out in four validation scenarios indicate that from the proposed architecture, it is possible to drive the AGVs without collisions, even in the communication network’s occurrence of delays and packet losses. In addition, tasks that demand more computational resources are offloaded to the edge server so that the computer embedded in the AGV can have more restricted resources, reducing costs and battery consumption.
