Item Proposta de relato integrado de valor para um curso de graduação em engenharia em uma universidade pública(Universidade Federal de Goiás, 2023-12-12) Santos, Diorgenes dos; Sousa, George Wagner Leão e; http://lattes.cnpq.br/1372987452901677; Severino, Maico Roris; http://lattes.cnpq.br/2546008836929749; Severino, Maico Roris; Soares, Júlio César Valandro; Zaro, Elise Soerger; Sousa, George Wagner Leão eThis research addresses the challenge that governance and management represent for public organizations, specifically an undergraduate course at a public university, and the need for tools that help in the task of analyzing, relating and interpreting information, minimizing risks and presenting important findings on how enterprises generate value for their stakeholders. The research proposes the structuring of an Integrated Value Report for an undergraduate course at a public university in the state of Goiás. It seeks to build the basis of the model, with a literature review on the CDIO Initiative, Management System with Agile SD as a control architecture approach and Integrated Reporting, seeking to determine the necessary requirements for the implementation of an Integrated Report and considering the possible definition of the Generic Architecture of Integrated Value Reporting for an undergraduate engineering course. The CDIO approach supports the understanding of the system's life cycle, considering interactions, innovation, improvement, user needs and technological constraints. Agile SD aids the understanding of causal relationships that influence past and future performance. Despite the growing importance of integrated reporting for governance and management, there is a lack of studies on integrated value reporting applied to undergraduate courses. This study seeks to fill this gap by proposing an integrated value reporting model for an undergraduate engineering course at a public university in the state of Goiás. This study will use a case study to verify and analyze the feasibility of implementing an Integrated Reporting model applied to an undergraduate course. The study will be carried out in an undergraduate engineering course at a public university in the state of Goiás. Overall, this study has presented solutions, tools and processes that can improve information management practices from an Integrated Value Reporting perspective, making a broad contribution to the maturing of governance and a specific contribution to the structuring of management processes from a systemic perspective, enabling greater precision on the points of investigation for decision-making and guiding the evolution of courses, which in turn can contribute to increasing their maturity.Item Caracterização tribológica das lâminas de corte de trituradores utilizados no processo de tratamento de resíduos sólido(Universidade Federal de Goiás, 2023-12-18) Souza, Willian Martins; Gonçalves Junior, José Lúcio; http://lattes.cnpq.br/2092647779902026; Bertholdi, Jonas; http://lattes.cnpq.br/0445297015533619; Bertholdi, Jonas; Troysi, Fernanda Christina Teotonio Dias; Ferreira Filho, DemóstenesIn Brazil, changes in production processes are observed due to environmental and social factors, which have as their biggest consequence the increase in the generation of solid waste. Because of these changes, it is essential to improve the efficiency of solid waste treatment processes, Thus, this work seeks to compare in laboratory tests the wear resistance of the cutting blades used in a solid waste crusher in the city of Aparecida de Goiânia, after application of different materials that can be used in the manufacture of the component, since the main problem presented was the loss in productivity in the treatment of waste due to wear of components of the crusher. After collecting a sample of cutting blade was identified through the study of Scanning Electron Microscopy (SEM) with Secondary Electrons (SE) and Backscattered Electrons (ERE), and also with Energy Dispersive Spectroscopy (EDS) that the type of wear preponderant in the tribological pair is the abrasive. From this premise, the laboratory experiment chosen was the rubber wheel wear test, because it is the method that best fits the system wear mechanisms, the same validated according to ASTM G-65. For the rubber wheel wear test were performed using samples of SAE 1060 steel and SAE 410 stainless steel heat treated. The studies demonstrated that it is not feasible to change the material used in the manufacture of the component, since the wear rates of the SAE 410D stainless steel samples were 55% higher than that of the samples that reproduce the condition of the cutting blade. This analysis is not limited only to one field, and can be extended to other sectors, using tribology as a reference, seeking to contribute to the academic production of production engineering, improving solid waste treatment operations.
