Item type: Item , Experimentação de um catálogo de padrões de requisitos de privacidade em conformidade com a lei geral de proteção de dados(Universidade Federal de Goiás, 2026-06-17) Portilho, Filipe Jesus; Bulcão Neto, Renato de Freitas; http://lattes.cnpq.br/5627556088346425; Canedo, Edna Dias; http://lattes.cnpq.br/9554285834432091; Graciano Neto, Valdemar Vicente; http://lattes.cnpq.br/9864803557706493; Ribeiro , Leonardo Andrade; http://lattes.cnpq.br/4036932351063584; Vincenzi, Auri Marcelo Rizzo; http://lattes.cnpq.br/0611351138131709[Context] Data privacy regulations are being created and made available to assist professionals in applying them throughout the Software Development Process (SDP). The General Data Protection Law (LGPD), for instance, introduces concepts regarding the privacy of individuals' data that must be considered from the early stages of a software project. [Problem] In response to the lack of knowledge or the difficulties most professionals face in making software compliant with the LGPD, various approaches have been proposed to incorporate the law's legal precepts into the Requirements Engineering (RE) process—such as solutions for reusing privacy requirements in the form of patterns, catalogs, and inventories. [Objective] Accordingly, this research aims to evaluate the Privacy Requirements Patterns Catalog (CPRP) with both students and professionals to measure ease of use, usefulness, and mental workload during RE activities supported by the CPRP. [Methods] To this end, a controlled experiment was conducted with students taking RE courses, alongside a user perception assessment involving professionals from a software development firm. [Results] Quantitative and qualitative assessment results show that students experienced a high workload when specifying privacy requirements (PRs) in compliance with the LGPD. Furthermore, both assessments—involving students and professionals alike—revealed that the CPRP had low ease of use; however, participants reported that the tool is useful and expressed an intention to use it for privacy-related RE activities. [Conclusion] Therefore, this research indicates that while the CPRP is useful for specifying LGPD-compliant PRs, its low ease of use necessitates usability improvements to enhance the user experience.Item type: Item , Plantas de cobertura e microrganismos multifuncionais no cultivo sustentável de soja e feijão-comum irrigado em sistema plantio direto no cerrado(Universidade Federal de Goiás, 2026-06-24) Ferreira, Izabely Vitória Lucas; Nascente, Adriano Stephan; http://lattes.cnpq.br/3194091518396388; Nascente, Adriano Stephan; http://lattes.cnpq.br/3194091518396388; Lacerda, Mabio Chrisley; http://lattes.cnpq.br/6994010761903559; Wander, Alcido Elenor; http://lattes.cnpq.br/8250997651281553; Silva, Mariana Aguiar; http://lattes.cnpq.br/3162335160875442; Filippi, Marta Cristina Corsi de; http://lattes.cnpq.br/0029536556461484EMBARGADO.Item type: Item , Psicologia e população em situação de rua na interface das políticas sociais: limites, contradições e possibilidades(Universidade Federal de Goiás, 2025-12-18) Fernandes, Estefania Cheruli; Lacerda Júnior, Fernando; http://lattes.cnpq.br/0864307656064852; Lacerda Júnior, Fernando; http://lattes.cnpq.br/6077243255728600; Oliveira, Isabel Maria Farias Fernandes de; http://lattes.cnpq.br/6077243255728600; Silva, Hugo Leonardo Fonseca da; http://lattes.cnpq.br/5824330405146391The Homeless Population (HPP) is a radical expression of the "social question" intimately linked to capitalist society. Transformations in the contemporary global societal structure: capital crisis, structural unemployment, the absence and/or fragility of public policies, precarious living conditions, and neoliberalism, have led to the expansion of the HPP. Along with this expansion, formal initiatives to address the issue have emerged, and research on this population has grown. This research sought to study the limits, contradictions, and possibilities of Psychology in Social Policies (SP) with homeless people, considering the Brazilian social formation. The theoreticalmethodological framework adopted to investigate and analyze the production of knowledge in Psychology about the HPP is Marxist-inspired. From the analysis of the works, we identified three analytical categories that express the conceptions of HPP adopted in the production of knowledge in Psychology: 1) superficial definition; 2) political, social, and economic influences; 3) “Social question”, multiple determinants and link to capitalist society. The analysis of the production of knowledge in Psychology about homelessness suggests that, for the most part, the works in Psychology do not always understand the structural dimension of the phenomenon, contributing to the naturalization of the existence of people living on the streets. The importance of encompassing capitalist society and the concrete economic, historical, social, and political dimensions that determine homelessness in the production of knowledge in Psychology is highlighted, as a way to affirm homelessness as a historically situated fact and to distance oneself from naturalizing, individualizing, and depoliticizing conceptions.Item type: Item , Avaliações frequentes, aprendizagens ausentes? Desafios contemporâneos no ensino de História na Rede Municipal de Goiânia(Universidade Federal de Goiás, 2026-02-23) Gonçalves, Luiz Eduardo; Nicolini, Cristiano; http://lattes.cnpq.br/3877723227851587; Andrade, Juliana Alves de; http://lattes.cnpq.br/9273063697259288; Pessoa, Raimundo Agnelo Soares; http://lattes.cnpq.br/5645430514881109This study aimed to analyze the History tests of the Bimonthly Elementary School Examination (EBEF) administered to students in the final years of elementary education within the Municipal Education Network of Goiânia between 2022 and 2025. The analytical framework was grounded in the assumptions of History Education, particularly in the contributions of the field of historical thinking. The analyses revealed the predominance of questions that primarily mobilize substantive or first-order knowledge, requiring students to identify, locate, and reproduce previously established information. Although the examinations include a variety of historical sources—such as texts and images—and address themes relevant to contemporary historiography, the interpretative and critical potential of these materials is often reduced by highly directive prompts and closed-ended alternatives that restrict the possibilities for reading and response. From this perspective, the EBEF tends to position students predominantly as recognizers of data and concepts, rather than encouraging the mobilization of second-order concepts such as historical evidence, causation, historical empathy, and continuity and change. Therefore, it is concluded that the examination limits the development of critical historical thinking, reinforcing a conception of historical knowledge centered on memorization and the recognition of information rather than on the interpretation and problematization of the past.Item type: Item , Síntese de eletrocatalisadores de paládio para produção de hidrogênio em eletrolisador ácido-alcalino(Universidade Federal de Goiás, 2026-04-30) Alexandre, Evelyn Christine Gonçalves; Léon, José Joaquin Linares; http://lattes.cnpq.br/5126547270872842; Pérez, Caridad Noda; http://lattes.cnpq.br/8518548259609686; Silva, Fábio Moreira da; http://lattes.cnpq.br/7599652290612173; Colmati Junior, Flavio; http://lattes.cnpq.br/0231242349462585This work aims to optimize the synthesis procedure for palladium nanocatalysts supported on carbon black Vulcan XC-72R (Pd/C) by chemical reduction with sodium formate, to maximize their performance in ethanol electro-oxidation and their application in an acid-alkaline electroreformer to produce green hydrogen. For this purpose, the influence of synthesis parameters, including reducing agent concentration, pH, reaction volume, and, ultimately, the atmosphere used, was investigated. The prepared materials were characterized by Inductively Coupled Plasma Optical Emission Spectrometry to confirm their composition, X-Ray Diffraction to assess crystallinity and average crystallite size, and Transmission Electron Microscopy to evaluate the nanoparticle size distribution. Next, the materials were tested for the reaction under study in a three-electrode cell to assess their electrochemical activity, a parameter directly related to green hydrogen production. Finally, the best material was tested in the acid-alkaline electroreformer, and an aliquot was collected to estimate the products formed and their distribution, with a view to their techno-economic impact on the process. The results demonstrated that pH is a crucial variable for achieving smaller particle sizes and more homogeneous distributions, with particle sizes in the range of 8-10 nm. This trend was further enhanced by using a 90:10 (vol.%) N2:H2 atmosphere, which halved the average particle size and notably increased particle size homogeneity on the support. These improved morphostructural properties resulted in the best oxidation performance, reflected in a maximum current density of 280 mA cm2. Furthermore, in spontaneous operation, stimulated by the favorable pH gradient, a maximum power density of 6 mW cm2.
