A atuação da Biblioteca Nacional no contexto da censura às obras literárias eróticas: abordagens do período da Ditadura Militar
(2023-10-23) França, Franciane Monick Gomes de; Frota, Maria Guiomar da Cunha; http://lattes.cnpq.br/5412492257148196; Greenhalgh, Raphael Diego; http://lattes.cnpq.br/4363292671692262; Silva, Carlos Henrique Juvêncio da; http://lattes.cnpq.br/1646741868261976; Hoffman, Felipe Eleutério; http://lattes.cnpq.br/3939955973103347; Silveira, Fabrício José Nascimento da; http://lattes.cnpq.br/8840124188505402
This research is a case study that aims to investigate and report how the censorship of literary books with erotic/sexual content occurred during the period of the Military Dictatorship (1964-1985), in the Brazilian National Library, as well as the role of Librarians in the face of censorship acts. From the theoretical reference and from a historical perspective, it had been mainly dealt with the following themes: censorship in the dictatorial period and its controlling instituitions, the bibliographic heritage as part of the country's collective memory and legal materials in the library area that had guided the professional ethics that had been performanced by the Librarians at the time. At the methodological level, documentary researches had been used, it had been taken place at the National files, to understand the survey of the censors and its preparation for carrying out the function, through the opinions of its Previous Censorship Series and administrative documents from the General Administration Section, both of them had been part of the Fund for Public Entertainment Censorship Division, the instituition responsible for centralizing censorship in the Military Dictatorship. The documentary research also includes administrative files from the National Library in regards to the dictatorial period, through the National Library Collection, under the custody of the Manuscripts Section, which contains administrative reports, statistic datas, correspondences, letters, and the Annual Management files wich are part of the General Archive and the Management Reports that appear in the Annals of the National Library. The documentary research aims to identify the presence of works examined by the censors, especially those one wich that had been prohibited. As the results, 78 books titles that corresponded to erotic, pornographic, obscene or about sexual education, in portuguese, were identified in the online catalog, from the total list of 673 in the Prior Censorship Series. It had been checked the existence of its files in the dictionary catalogue, used at the time to identify the works that made up the collection. It had been also included in the methodology some interviews and e-mail correspondences with employees of the National Library, resulting in 1 testimony and 3 reports of episodes about government and librarian activities. By analyzing the data collected, it had been found from the 78 books included in the collection that 52 were prohibited, 20 were released and 6 were absent, which 75 of them were acquired by legal deposit. The actions that had been taken by Librarians to protect prohibited publications included hiding them in safes and cabinets, removing identification cards, changing shelves and sections. In terms of government practices, it had been noticed the presence of agents of the dictatorship to supervise these works in an official and camouflaged way. It had been concluded that there was a governmental censorship supervisory action, without legal determination embargoing the acquisition of publications, but seeking to subsequently remove certain articles from the collection, and that on the part of some employees, including Librarians, there were strategies of resistance to censorship and safeguarding of works restrained.

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.

Environmental Education (EE) is essential in today's context, standing out in the face of global challenges such as excessive consumption, deforestation and pollution. Events such as the Stockholm Conference (1972) and COP 27 (2022) highlight advances in sustainable development. In Brazil, the National Environmental Education Policy (PNEA) faces difficulties, such as the lack of teacher training and the prioritization of other school content. Although EE plays a central role in integrating society and nature, its application in schools is often punctual and limited, facing obstacles such as the use of traditional methods and the absence of integrated projects. The aim of this end-of-course work was to carry out a situational diagnosis of environmental education in the Integrated Technical Courses at the Instituto Federal de Alagoas (Ifal) and to encourage its implementation at the institution. The research was exploratory, classified as bibliographical and documentary, and applied to the 15 Ifal campuses that offer Integrated Technical Courses. Data collection included analysis of official documents, recent bibliography and the Integrated Academic Activities Management System (SIGAA) to identify projects related to EE. In education, an analysis of the Pedagogical Course Projects (PCP) was carried out, which made it possible to identify that the environmental theme is approached unevenly when comparing intercourses and intra-courses on different campuses. The analysis of the PCP indicates that environmental education is present, but needs more consistency and depth. Terms such as “Environmental Education” and “Sustainability” are more common in agricultural and environmental courses, while technological areas show little integration. A questionnaire was validated using the Delphi Technique and then applied to teachers. The validation process resulted in a questionnaire used to assess the effective implementation of EE at Ifal and the position of teachers in relation to the sustainability practices adopted in their daily lives. The application of the Delphi method improved the questionnaire, especially in terms of the relevance and clarity of the questions. The main adjustments to the questionnaire focused on replacing terms, making the analysis tool more objective. The Delphi method made it possible to produce a research tool capable of identifying the reality of environmental education practice at Ifal and to draw up a profile of the teaching staff in relation to the implementation of educational activities aimed at environmental education. As for extension, the results show that Ifal promotes environmental education through actions concentrated on a few campuses and specific categories. However, there has been a drop in these actions over the last three years, possibly due to the pandemic. In addition, a training course in environmental education was designed for Ifal teachers, with the aim of improving their approach to environmental issues. In this sense, it is crucial to disseminate information and promote responsible attitudes that help develop students as conscious citizens. Therefore, learning tools should provide greater freedom and autonomy, allowing students to develop skills and understand the reality in which they are inserted. Technical reports with the conclusions of the research were produced and made available to the institution, with the aim of collaborating with future EE initiatives in teaching, research and extension.

The allocation of the low voltage electrical power general distribution board at buildings is determined by technical, normative and economical parameters. A properly allocation of the low voltage main board reduces the wiring lengths of the feeders and distribution circuits designed for the installations, and, consequently, reduces the deployment costs as well the operative costs (power consumption) related to power dissipation (Joule heating). This work aims to develop and apply an optimization model for the optimal location determination of the low voltage main board at houses, flats, commercial buildings and small industries. To solve this problem, it has been adopted a network optimization model to determine the shortest route to pass the conductors, in which results in costs reduction. For validation of the proposed solution, it was performed a case study, where, taking real parameters, the definition of an optimization technique executed in Excel Solver, has indicated a point considered as the optimal location of the low voltage main board. Then, the obtained results were compared to location returned by load center, method traditionally used. From this comparison, it was verified the efficiency of the suggested method assuring a reliable and economical decision making.
Análise da comunicação no setor operacional usando equações estruturais: uma ferramenta de apoio ao gerenciamento da informação
(UNIVERSIDADE FEDERAL DA BAHIA - UFBA, 2021-06-15) Drigo, Edmara dos Santos; Rodríguez, Jorge Laureano Moya; http://orcid.org/0000-0003-0541-0191; http://lattes.cnpq.br/5576711447768585; Ávila Filho, Salvador; https://orcid.org/0000-0002-5006-1501; http://lattes.cnpq.br/8080668192694401; Souza, Marcelo Embiruçu de; http://lattes.cnpq.br/8281601894113525; Rodríguez; Rodriguez, Carlos Manuel Taboada; https://orcid.org/0000-0003-2328-378X; http://lattes.cnpq.br/5905893327298080; Leite, Jandecy Cabral; https://orcid.org/0000-0002-1337-3549; http://lattes.cnpq.br/7279183940171317; Lima, Orlem Pinheiro de; https://orcid.org/0000-0003-1007-0734; http://lattes.cnpq.br/8148029403735260; Fontes, Cristiano Hora de Oliveira; https://orcid.org/0000-0001-8020-6815; http://lattes.cnpq.br/8533422209857268
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.
Análise do discurso do operador e seu instrumento de comunicação entre turnos como ferramenta para o sistema de gestão
(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2016-06-06) Drigo, Edmara dos Santos; Oliveira, Cristiano Lessa de; http://lattes.cnpq.br/1436093029977246; Ávila Filho, Salvador; https://orcid.org/0000-0002-5006-1501; http://lattes.cnpq.br/8080668192694401; Marques, Sheyla Karolina Justino; https://orcid.org/0000-0001-7554-2275; http://lattes.cnpq.br/3917387578549073; Costa, Israel Crescencio da; http://lattes.cnpq.br/7663274879776157; Esquerre, Karla Patricia Santos Oliveira Rodríguez; https://orcid.org/0000-0001-8799-7365; http://lattes.cnpq.br/1956096628005272; Fleming, Paulo Victor; http://lattes.cnpq.br/1313976268089270
Communication in organizations is still a difficult obstacle to be transposed. Effective instruments for transmission of information and the advent of technologies still need to rely on motivational and highly subjective factors that will make a man in his job routine report abnormalities or shut. Considering the operator discourse as a valuable tool for abnormalities display operational plan and support for decision-making in the management field, this dissertation aimed to analyze the communication between operators and shifts in a Water Treatment Plant (WTP) in the Northeast of Brazil. Problems in the information flow can result in operational failures in this case represent a risk to public health. The qualitative and quantitative analysis of records of operators and their communication tool show weaknesses in the shift book format used in WTP in question. The analysis of the text written by the operators based on analytical categories of Critical Discourse Analysis suggests the existence of conflicts that affect the organizational climate. We proposed a model instrument for communication in turn in checklist format to replace the typical procedure in narrative style. Although the focus of this work is the written speech, the operator’s speech in all its forms, can contribute significantly to the management system, but this management style should consider issues relating to human reliability and be willing to make procedure and structural changes.
Análise do plano de gestão de resíduos de serviços saúde de estabelecimentos do Estado de Alagoas

Waste is the material that remains or that is undesirably generated in an activity. Healthcare Waste (HW) is that produced by any agent of prevention, maintenance or recovery of human or animal health or aesthetics. The increase in the population and the growth in demand for health and beauty procedures drive the generation of HW, causing health risks to those who come into contact with it. In Brazil, health, environmental, labor or metrology surveillance institutions issue standards, such as RDC nº 222/2018 from Anvisa and ABNT NBR 12808:2020, which aim to regulate activities so that harm to humans and the environment is avoided or, at least, minimized. One of the regulatory requirements is that each generator prepares and executes a Health Service Waste Management Plan (HWMP), making it available to anyone who wishes to consult it. This is an essential document for the provider to obtain the environmental operating license. Thus, the main objective of this study is to analyze the compliance of the HWMP with the current related standards. To this end, a theoretical framework for analysis (TFA) was developed, with each item based on the rigor of the available standards and literature, to serve as a parameter. In order to compare them among themselves, as well as not to expose the institution, each establishment was identified by the acronym HWG (healthcare waste generator) followed by the number corresponding to the position of the decreasing number of pages of its HWMP. A methodology was used that assigns scores of 5 (five), 3 (three) or 0 (zero), depending on whether the item of the Plan is fully, partially or not answered, respectively. Of the approximately 130 establishments consulted, only 13 made their HWMP available, and of these, the majority through the Access to Information Law. The TFA was structured with 70 questions grouped into six items. On this scale, each HWG could obtain up to 350 points. However, the scores ranged from only 137 (HWG13) to 243 (HWG5), that is, they are between 39% and 69% of an ideal standard, with five of them below 50% compliance with health and environmental standards. Given the limited availability of PGRSSs and the poor adherence to the standards of those that were analyzed, it is concluded that this document is absent in many establishments in the State of Alagoas and, in those that do exist, improvements are needed.
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.

This research aimed to contribute to the educational process of students of the Integrated Technical Course for High School Education in Roads, of the Federal Institute of Education, Science and Technology of Alagoas (Ifal), Maceió Campus, by expanding the dissemination and understanding of the fundamental concepts that underpin Professional and Technological Education (EPT). To this end, the investigation proposed to answer the following research question: how can expanding the dissemination and understanding of the fundamental concepts that underpin EPT contribute significantly to the educational process of students of the Integrated Technical Course for High School Education in Roads of Ifal, Maceió Campus? This study was based on a theoretical framework, based on the assumptions of authors such as Kuenzer (1992), Saviani (1994; 2007), Gramsci (1977), Ramos (2008), Frigotto, Ciavatta and Ramos (2010), Manacorda (2010), Pacheco (2011; 2012), among others, whose contributions were essential for the understanding and analysis of the data collected. The research adopted a quantitative and qualitative approach, using as the main data collection instruments the application of questionnaires directed to students in the 1st year class, whose answers were later analyzed and discussed in light of the established theoretical framework. The results of the research highlighted the importance of students knowing the conceptual foundations of their course. However, regarding the relevance of the work, the study revealed that this dimension is still predominantly focused on the historical aspect, to the detriment of the ontological aspect. Based on the results obtained, an educational product was developed focusing on the conceptual bases of High School Integrated with EPT, through the systematization of five meetings mediated by a script. This educational product aims to provide students with a deeper understanding, especially of the dimension of work as an educational principle. In this way, this work offers theoretical contributions to the field of EPT, in addition to presenting a practical application of these concepts through the development of the aforementioned educational product, a comic book magazine.

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.

The sururu production chain is characterized by human suffering, from fishing to packaging. It can be divided into stages: fishing or gathering, washing, despining, cooking, peeling or deshelling, bottling and marketing. The step to peel or deconch it occurs through sieving. It is carried out mainly by women and children, who are subjected to great physical effort, as it is a completely manual operation. They are exposed to terrible ergonomic conditions and receive the lowest pay in the entire production chain. In this context, mechanization and automation are seen as a viable solution to reduce human suffering and the evolution of processes and products. The objective of this work was to expose, in an organized way, the technical and intellectual productions, during the Postgraduate Program Analysis of Environmental Systems, at Centro Universitário CESMAC, to develop a prototype built with recycled or reused materials, capable of peeling sururu and reduce the pain of seafood restaurants. This prototype for sifting sururu should improve the quality of life of workers involved in this production chain. The reduction of physical efforts resulting from its use should also reduce the emergence and incidence of muscle injuries and injuries. For its construction, experimental research was initiated, which included a literature review, patent prior research and the use of tools and software for projection, modeling and manufacturing. The prototype consists of a perforated and rotating basket, through which the molluscs fall and the shells are retained inside. As for its operation, when activated, an electric motor on the prototype produces the rotational movement of the perforated basket and the sururus that pass through the holes fall onto a tray placed at the base of the equipment. After completing the operation, the sururus must be collected and the shells must be discarded or reused appropriately. The research was carried out at the Shared Innovation and Technology Laboratory (Colab), of the Federal Institute of Education, Science and Technology of Alagoas (IFAL), Campus Maceió, with support from projects promoted by technological innovation notices, in addition to partnerships with institutions, non-governmental organizations and cooperatives. It begins the transition to the manufacturing process and should be expanded to generate new products, with the aim of serving other activities in the sururu production chain. Currently, research on the ergonomic impacts in the sieving stage is being developed, through which it will be possible to evaluate the benefits of using the prototype. And research to carry out tests with the purpose of establishing optimal operational parameters must be carried out.
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.

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.

Unbridled energy consumption is one of the main causes of environmental problems that threaten life on Earth, such as climate change, air pollution, global warming, and greenhouse gases. Consequently, reducing CO2 emissions has emerged as a major modern global concern. Therefore, energy efficiency is seen as a fundamental step towards achieving sustainable development. Studies indicate that public buildings consume significant amounts of electricity and waste a lot of it, and that there is a direct connection between the energy use of buildings, their efficiency, and the improvement of their environmental sustainability indicators. Based on this scenario, a study aimed to evaluate the energy efficiency and environmental indicators of the electricity consumption of a public educational building. The study enabled the scientific production of a Book Chapter that aimed to evaluate the energy efficiency of a public building and environmental indicators based on energy consumption, using for this a case study at IFAL - Federal Institute of Science and Technology of Alagoas, Maceió campus, using as a methodology to quantify efficiency the Technical Regulation for the Quality of the Energy Efficiency Level of Commercial, Service and Public Buildings (RTQ-C) and in the evaluation of sustainability indicators applied to the ecological footprint and carbon footprint, thus proposing solutions to increase energy efficiency and reduce CO2 emissions. This study enabled the approval of the research project in PISIC 2003-2004, which allowed the integration of students and professors from the civil engineering and PPGASA courses of CESMAC, as well as contributions to the dissemination of the theme with publications of abstracts in annals and presentations, oral and on banners, of works in national and local congresses, where a bibliographic review, data collection, possible results and proposals for researched solutions were presented. As a technical production, a training course was held for students graduating from the electrical engineering course entitled “Energy consumption and environmental sustainability of a building”, with the objective of raising awareness among future industrial technicians in electrical engineering of the direct relationship between the consumption of electrical energy in a building and the influences on the environment, training professionals with a broader perspective of sustainability. In this training, teaching activities were used, increasing the direct involvement of students in the training, leading them to reflect on the degree of importance that professionals in this area influence the relationships of environmental sustainability on our planet. In view of the results obtained, the public school building was classified as having level B efficiency, contributing to CO2 emissions of 82.13 tons/ CO2/year through the consumption of electrical energy, resulting in a carbon footprint of 6.10 kg CO2/m²/year and an ecological footprint of 11.52 ha. Sustainable alternatives in the building regarding lighting, envelope and air conditioning systems imply a reduction of 26.52%, resulting in a saving of 395 MWh/year of energy, stopping the emission of more than 21,764 tons of CO2/year into the atmosphere.
"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.

(2021) Silva, Alessandra Vieira da; Brum, Evanisa Helena Maio de; Barbosa, Kevan Guilherme Nóbrega; Trindade Filho, Euclides Marinho; Verçoza, Lúcio Vasconcellos de; Nóbrega, Diego Figueiredo; Mousinho, Kristiana Cerqueira; Rocha, Thiago José Matos
Suicide has been a worldwide problem that has affected the lives of millions of people around the world. The World Health Organization estimates that the annual number of people who commit suicide is twice that of homicide. The aim of this study was to perform a temporal and spatial analysis of suicidal violence in the metropolitan region of Maceió - AL, describing the sociodemographic characteristics, related to the place of residence, place of occurrence, in addition to the characteristics related to the event itself. This is an observational epidemiological study, with a quantitative method approach. To investigate the associated factors-time-space triad, data were collected from the Instituto Médico Legal Estácio de Lima de Maceió from 2016 to 2018, and from the Mortality Information System for the period from 2000 to 2019. A modeling was used. statistical analysis through multiple logistic regression, using males as the reference category for the analysis, where the Odds Ratio (OR) values were calculated using the binary method, estimating the Confidence Interval (CI) of 95%. The prerequisites for the regression were the absence of multicollinearity (autocorrelation of the independent variable with the outcome), expressed as Tolerance values > 0.1 and VIF values < 10, another item observed was the absence of outliers. The choice of the final model observed the significance of the model, the R Square of Nagelkerke, the classification capacity of the model and the significance of Hosmer and Lemeshow. In all analyses, the significance level was set at 5%, using the SPSS statistical package (version 20.0) to aid in data processing. Results of the present study indicate that the pattern of victimization for suicide in the MR of Maceió is predominantly male and that it affects individuals of mixed ethnicity, single, salaried, whose residence and occurrence is mainly in the city of Maceió. Hanging was the main mechanism of suicide, followed by poisoning and intentional falling. Weekends and Fridays were the days with the highest occurrence of cases. Factors associated with male suicide indicated that they are related to ethnicity, work status, mechanism of suicide and trimester of occurrence. Suicide rates were higher in men, ranging from 4.1-7.6 x 100,000 population compared to female victims 2.9-4.1 x 100,000 population. The city of Barra de São Miguel had the highest suicide mortality rate, followed by Maceió, Marechal Deodoro, Rio Largo and Pilar. The capital Maceió has the highest number of cases and place of residence of the suicide act. We conclude by showing that there was a significant increase in suicide notifications between 2000 and 2009. This increase was mainly explained by the increase in notifications of female victims, within the same period considered. The present study had limitations based on the use of secondary data on suicide mortality, coming from a system that is subject to underreporting and inadequate filling in the documentation used to record these data, as well as in the system's feed.
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.

(2025) Albuquerque, Cassiano Henrique de; Cavalcante, Patrícia Smith; Cavalcante, Patrícia Smith; Carvalho, Ana Beatriz Gomes Pimenta de; Lopes, Andiara Valentina de Freitas e; Castro, Juscileide Braga de; Pereira, Renata Imaculada Soares
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.
