Item 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/8840124188505402This 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.Item 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/8996477208727758En 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.Item A educação ambiental nos cursos técnicos integrados ao ensino médio(2024) Bomfim, Deisy Anny; Santos, Aldenir Feitosa dos; Bassi, Letícia Anderson; Vilela, Lívia Maria Batista; Silva, José Atalvanio daEnvironmental 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.Item Acoustoelastic response in rebars of reinforced concrete structures(2025) Vasconcelos, Thiago Delfino Lima; Haach, Vladimir Guilherme; Haach, Vladimir Guilherme; Carrazedo, Ricardo; Santos Júnior, Auteliano Antunes dos; Ferreira, Gisleiva Cristina dos Santos; Pinto, Roberto Caldas de AndradeItem Alocação adequada do quadro geral de baixa tensão através da busca pelo caminho mais curto(2018) Abreu, Jacksiel José de; Cavalcante, Carlos Arthur Mattos Teixeira; Cavalcante, Carlos Arthur Mattos Teixeira; Sant’Anna, Ângelo Márcio Oliveira; Claudino, Elder de SouzaThe 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.Item 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/8533422209857268The 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.Item 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/1313976268089270Communication 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.Item Análise do plano de gestão de resíduos de serviços saúde de estabelecimentos do Estado de Alagoas(2025) Silva, Ivonaldo Gomes da ; Santos Filho, Moézio de Vasconcellos Costa; Sant’Anna, Selenobaldo Alexinaldo Cabral de; Santos, Aldenir Feitosa dos; Miranda, Paulo Rogério Barbosa de; Ribeiro, Cássia Roberta PontesWaste 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.Item Análise do processo formativo dos professores indígenas na educação escolar(Centro Universitário de Maceió – Unima | Afya, 2025-08-06) Jesus, Claudia Maria Rodrigues de; Pereira, Jesana Batista; https://orcid.org/0000-0003-2971-9855; http://lattes.cnpq.br/2329848572181989; Cruz, Cristiane Monteiro da; https://orcid.org/0000-0002-2912-9137; http://lattes.cnpq.br/5492075983298968; Minatel, Vinicius; https://orcid.org/0000-0002-0916-2546; http://lattes.cnpq.br/2451652025356071; Vieira, Jorge Luís GonzagaLa formación de profesores indígenas es una cuestión actual en la política educativa brasileña y se presenta como uno de los principales desafíos para la consolidación de la Educación Escolar Indígena. A pesar de la importancia de la formación de profesores indígenas y de la existencia de una legislación específica, hay pocas investigaciones en el ámbito de las políticas educativas sobre el proceso formativo de los profesores que trabajan en las escuelas indígenas. Para cubrir esa laguna de investigación, este estudio tuvo como objetivo investigar el proceso formativo de los profesores indígenas, considerando las políticas públicas que lo influyen. Como base teórica, se apoya en los estudios sobre Educación Escolar Indígena y en la política de formación docente, incorporando además la perspectiva de una formación basada en los principios de promoción de diálogos interculturales entre diferentes conocimientos, en la articulación de los diversos espacios formativos y en el reconocimiento de una educación específica y diferenciada. Se realizó un estudio de caso cualitativo en escuelas indígenas estatales. El instrumento utilizado para la recolección de datos fue la entrevista presencial y el análisis documental. Para el análisis de datos se utilizó como referencia la análisis temática de contenido de Bardin. Los resultados indican la ausencia o desconocimiento de políticas públicas sistemáticas y estructuradas para la formación de profesores indígenas, evidenciando lagunas institucionales que comprometen la valorización profesional de estos docentes, así como la calidad de la educación ofrecida a las comunidades indígenas. Esta realidad resalta la necesidad de fortalecer las políticas y prácticas formativas que reconozcan las especificidades culturales, promuevan el diálogo intercultural y garanticen condiciones adecuadas para el ejercicio de la docencia en las escuelas indígenas. Este estudio contribuye al profundizamiento de las discusiones sobre la formación docente indígena, al enfatizar la construcción de procesos formativos críticos sostenidos en el diálogo intercultural entre distintos sistemas de conocimiento.Item As competências do servidor público e seus impactos(FACULDADE FUCAPE - FUCAPE, 2023-03-07) Nogueira, Eduardo Henrique Brandão; Mainardes, Emerson Wagner; https://orcid.org/0000-0003-2525-275X; http://lattes.cnpq.br/9828374447862752; Campagnaro, Arilda Magna Teixeira; http://lattes.cnpq.br/2865705161924839; Pascuci, Lucilaine Maria; http://lattes.cnpq.br/5674113274785826This research aimed to verify whether civil servant competencies (self-competence, team competence, change competence, communication competence and ethical competence) influence the organizational commitment of civil servants and indirectly their job satisfaction. In this context, the concepts of the five dimensions of the competency scale, organizational commitment, and job satisfaction of civil servants were studied, as well as the relationships among these constructs. From a structural model based on the literature, a survey was carried out, by means of a questionnaire, with 463 civil servants, aiming at collecting data to measure and analyze the constructs and the relationships among them. To evaluate the measurement model, a confirmatory composite analysis was performed. Then, the structural equation modeling technique with partial least squares estimation (PLS-SEM) was used to analyze the structural model. The results showed that the ethical competence construct tends to have a direct positive influence on the organizational commitment construct, and tends to indirectly influence job satisfaction among civil servants. On the other hand, it was perceived that the constructs self-competence, team competence, change competence and communication competence did not have an impact on the organizational commitment of civil servants, nor on their job satisfaction. It is concluded, therefore, that the development of civil servants’ ethical competence will probably result in an increase in their organizational commitment and, indirectly, this will positively affect their job satisfaction.Item As ferramentas virtuais não exclusivas à aprendizagem e suas implicações nos saberes e na inter-relação professor-aluno : uma investigação a partir da ótica docente no IFAL Campus Maragogi(UNIVERSIDADE ESTÁCIO DE SÁ - RIO DE JANEIRO , 2026-02-27) Ferreira, Jairo Santos; Saldanha, Luís Cláudio Dallier; https://orcid.org/0000-0003-3822-1477; ttp://lattes.cnpq.br/6177663314282321; Pedrosa, Stella Maria Peixoto de Azevedo; https://orcid.org/0000-0002-8844-2043; http://lattes.cnpq.br/6986927279922334; Gomes, Nataniel dos Santos; https://orcid.org/0000-0003-3911-1552; http://lattes.cnpq.br/6180920530799182This qualitative research, conducted as a case study, sought to investigate the use of Virtual Tools Not Exclusive to Learning (VTNExL) as a didactic-pedagogical strategy by professors at the Federal Institute of Alagoas (IFAL), Maragogi campus, from the perspective of the educators themselves. To this end, a survey was conducted on the use of VTNExL for didactic mediation through the implementation of teaching and research activities/projects aimed at the development and learning of various subjects offered at IFAL Campus Maragogi. The study identified the professors' degree of familiarity with VTNExL, the knowledge acquired and shared through its use, and the influence of these tools on the teacher-student relationship, in order to detect which VTNExL are most frequently used and to understand their scope and effectiveness for the intended purposes. This research project is justified by its academic contribution regarding the development of the didactic-pedagogical application of different technological resources for teaching and learning, and as an influential means of connection between teachers and students. The research involved the application of semi-structured questionnaires, provided via Google Forms and composed of both closed and open-ended questions, to collect information from the participating subjects (professors from the Maragogi campus). Additionally, non-directive interviews were conducted to gather more elucidative information from their free discourse while minimizing risks of embarrassment or discomfort to the research subjects. Through this research, a consolidation of the use of platforms such as YouTube, WhatsApp, and Artificial Intelligence was identified, which have been re-signified by professors as teaching tools. The study concludes that the teacher is the essential "agent" in the transformation of an ItemNet into a VTNExL, acting as a critical mediator who balances generational proximity with the ethical and pedagogical boundaries of technology. It was also found that while VTNExLs enhance student autonomy and engagement, their implementation requires vigilance against the limiting structures of digital tools and algorithms.Item 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/5271094336884473Urease 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.Item Ciências comportamentais no setor público: evidências sobre a teoria dos prospectos e a utilização do dissidente estratégico na governança.(UNIVERSIDADE FEDERAL DE ALAGOAS - Ufal, 2023-04-17) Santos, Elaine Cristine Rodrigues dos; Prazeres, Rodrigo Vicente dos; https://orcid.org/0000-0002-9888-1330; http://lattes.cnpq.br/6948481293326184; Prazeres, Rodrigo Vicente dos; https://orcid.org/0000-0002-9888-1330; http://lattes.cnpq.br/6948481293326184; Silva, Wesley Vieira da; https://orcid.org/0000-0001-5354-8676; http://lattes.cnpq.br/1710286275396858; Anjos, Luiz Carlos Marques dos; https://orcid.org/0000-0002-7375-540X; http://lattes.cnpq.br/2136400491380618; Lima Filho, Raimundo Nonato; https://orcid.org/0000-0003-4953-5260; http://lattes.cnpq.br/8371310058634760The foundation of Economic Theory is based on the rationality of the human being. However, the behavioral sciences show that the individual makes decisions that escape from the rational model. Thus, this research aims to investigate and describe the manifestation of behavioral heuristics and biases in Brazilian public administration employees, in decision scenarios under conditions of risk, and, in a second step, aims to analyze the use of the strategic dissenter as a behavioral tool to avoid or reduce biased decisions within the public sector governance model. The study was conducted by the experimental method, with intentional manipulation of independent variables in randomized comparison groups. A total of 162 employees of a federal public institution in the state of Alagoas participated in the research. The first stage of the research was based on the Prospect Theory. The results suggest that the participants were influenced by the framing effect, the anchoring heuristic, the proportional dominance bias, and the asymmetric dominance bias. No evidence of the status quo bias was found during the experiments. In the second stage of the research, it was observed that a scenario formed by a group of people whose opinions are divergent was not sufficient to create the cognitive dissonance capable of reducing confirmation bias, groupthink, and commitment escalation. Although, evidence was found that the use of the strategic dissenter modified the choice of the servers participating in the research, preventing or minimizing the manifestation of biases in the organizational environment of public governance. In addition, the age, time of work, and gender of the public employees who participated in the research had no influence on the dissident's action. It was concluded that the participants in this scientific study did not strictly follow the rational model in their choices, violating the Expected Utility Theory, and that the use of the strategic dissenter was necessary to reduce biased decisions that could impact actions in public governance. This study contributes in the theoretical sphere with new evidence for understanding behavioral phenomena in public administration and with fostering academic discussions to improve the architecture of choices in public management. The findings also point to the relevance of considering a behavioral pillar in the Brazilian public governance model. In the practical field, the evidence contributes to help public management understand the cognitive limitations of civil servants and implement routines and processes that can optimize decisions guided by the efficient and effective use of public resources, as advocated by the public governance model.Item Conceitos da EPT em quadrinhos: uma proposta de popularização do conhecimento científico(2024-09-30) Machado, Itajaci Meiri Marques; Silva Júnior, José Espínola da; http://lattes.cnpq.br/2240211724270086; Silva Júnior, José Espínola da; Santos, Elza Ferreira; http://lattes.cnpq.br/2729412597740900; Santos, Marilene; http://lattes.cnpq.br/6890789604708020This 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.Item Desenvolvimento de modelos preditivos para avaliação de paisagem sonora com base em levantamento na orla marítima da cidade Maceió-AL(2025) Santos, Jordana Teixeira da Silva Lima; Oiticica, Maria Lúcia Gondim da Rosa; Toledo, Alexandre Márcio; Cavalcante, Morgana Maria Pitta Duarte; Miranda, Erasmo Felipe Vergara; Michalski, Ranny Loureiro Xavier NascimentoIn 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.Item Desenvolvimento de uma peneira de baixo custo para descascar sururu(2023) Silva, Allisson Luiz Nascimento da; Silva, Juliane Cabral; Souza, Mayara Andrade; Carvalho, Ciro Ramon Felix dos Santos; Omena, Rômulo Afonso Luna Vianna deThe 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.Item 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 BarrosThis 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.Item Efeitos das tecnologias de realidade aumentada e virtual como recursos visuoespaciais na aprendizagem de geometria molecular(2024-10-14) Silva, Kleyfton Soares da; Correia, Paulo Rogério Miranda; http://lattes.cnpq.br/1028921713215334; Correia, Paulo Rogerio Miranda; http://lattes.cnpq.br/1028921713215334; Aguiar, Joana Guilares de; http://lattes.cnpq.br/7322160560603795; Cirino, Marcelo Maia; https://orcid.org/0000-0002-5377-382X; http://lattes.cnpq.br/7952492082756341; Gotuzo, Seabra, AlessandraThis 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.Item Eficiência energética e indicadores ambientais sobre o consumo de energia elétrica em uma edificação pública(2024) Rocha, Jean Jacques Bittencourt da; Souza, Mayara Andrade; Sant'Anna, Selenobaldo Alexinaldo Cabral de; Silva, Magno José Gomes da; Braga, Mauro SérgioUnbridled 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.Item "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 JoséThis 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.
