It was developed within the "Dynamics and Environmental Management in Subtropical Zones" research area of the Graduate Program in Geography at the State University of Western Paraná (UNIOESTE), Marechal Cândido Rondon Campus. This research aims to investigate the adoption of geotechnologies in the fourth and fifth grades of the 18 municipal schools in Marechal Cândido Rondon between 2024 and 2026, seeking to gain a deeper understanding of how they are utilized and the challenges limiting their more effective integration. The rapid adoption of digital technologies in schools and shifting student interests necessitate the adoption of new methodologies; thus, this study explores methodological alternatives suited to this context. Through a systematic literature review, the work analyzes the use of geotechnologies—such as Google Maps, Google Earth, digital cartography, and interactive maps—in geography classes, as well as teachers' perceptions regarding proposed practices and pedagogical potential. The theoretical framework encompasses concepts such as geoprocessing, geographic information systems (GIS), remote sensing, and geolocation, considering their pedagogical relevance and the specific characteristics of geography education in the early years. The study employs a qualitative design with descriptive and exploratory characteristics, integrating a literature review with data collection via an electronic questionnaire administered to teachers in the municipal school system. The total number of teachers who responded to the survey constitutes a representative sample for the study. This methodological approach enabled the identification and analysis of teachers' perceptions regarding the potential use of geotechnologies within their respective schools, providing an in-depth understanding of their views on the feasibility and applicability of these technological tools in their specific educational contexts. Subsequently, data were collected on the geotechnological practices adopted by these teachers as methodological aids. The results include a positive assessment of geotechnology use, the systematization of activities gathered from teachers, the identification of best practices, the formulation of proposals based on these suggestions, an understanding of pedagogical relevance, contributions to the theoretical framework, and guidelines for future implementation—all offering valuable insights for enhancing the integration of geotechnologies into geography education. However, the research also revealed significant challenges faced by teachers, most notably a lack of specific training and adequate preparation for using these technologies, as well as a limited range of equipment necessary for their effective classroom implementation. The use of geotechnologies in schools has generally been sporadic and unsystematic, often restricted to the digital interactive whiteboard—a fixed, teacher-centered tool that limits activities designed to foster student autonomy and active engagement. This setup can hinder collaborative practices, the development of inquiry skills, and the exploratory use of tools by students, although—despite these obstacles—it does not entirely prevent the execution of certain tasks.

La investigación parte de la problemática de comprender cómo estos trabajadores construyen sus trayectorias laborales, elaboran significados en torno al trabajo temporal y negocian sus condiciones de vida frente a las transformaciones provocadas por la expansión de la agroindustria regional. Al problematizar las interpretaciones que los presentan únicamente como sujetos determinados por las estructuras económicas, el estudio busca poner de relieve sus formas de agencia, sus estrategias de permanencia, movilidad y construcción identitaria. Fundamentada en los presupuestos de la Historia Social, con el respaldo de los estudios de Thompson (1978) y Scott (2011), y privilegiando la experiencia histórica de los sujetos y sus relaciones sociales, para la elaboración de este trabajo se utilizaron entrevistas realizadas a trabajadores, expedientes judiciales laborales, contratos de trabajo, recibos de salario y noticias periodísticas. El diálogo entre estas diferentes fuentes permitió analizar tanto las condiciones objetivas de inserción de estos trabajadores en el mercado laboral como las interpretaciones construidas por ellos acerca de sus propias experiencias. De este modo, el trabajo temporal no puede comprenderse únicamente como una expresión de la precarización de las relaciones laborales, sino también como un espacio de construcción de identidades, expectativas y elecciones, revelando la complejidad de las experiencias vividas por los trabajadores de los silos de almacenamiento de granos en la región occidental del estado de Paraná.

It further seeks to examine how those actors contributed towards the construction of a Vargas nation-state based on the ideology of racial harmony. The study focuses on the scenario of the state of São Paulo (capital of São Paulo) and the Federal District (Rio de Janeiro), articulating local dynamics with central government guidelines. The work seeks to unveil the narrative disputes and contradictions between the erasure of black protagonism by the official discourse, which monumentalized the figure of Princess Isabel as "Redeemer", and the resistance and political agency of organized black movements of the period. While centering on the year 1938 (the context of the fiftiethanniversary commemoration), the study also looks back at the years 1931–1937 to analyze the planning and trajectories of Black associations prior to the forced closures imposed by the Estado Novo dictatorship. To this end, the research draws on official documents (The Constitution of 1937 and the Decree-Law nº 427 of May 13, 1938 ) and correspondence (from the Gustavo Capanema Archive), on the commercial press and from mass circulation newspapers such as O Globo, O Jornal, Correio Paulistano and Revista do Arquivo Municipal de São Paulo (RAM), on the Black press and movement, considering the periodicals A Voz da Raça (associated with the Frente Negra Brasileira) and Clarim da Alvorada (associated with the Clube Negro de Cultura Social). The analysis of this commemorative event as a “place of memory” reveals the dispute over collective memory and national identity between the Estado Novo — occasionally backed by intellectuals — and Black associations. These associations had operated autonomously prior to the Estado Novo but, due to censorship, were forced to adopt a diluted and officially apolitical stance following the coup of November 10, 1937. The diverse types of sources helped construct a picture of a period overshadowed by the Integralist Uprising of May 11, 1938 — occurring just two days before the anniversary itself — which impacted the execution of planned commemorative activities. Consequently, the research sought to demonstrate how the fiftieth anniversary of abolition became a vehicle for the Getúlio Vargas government to monumentalize the past in the name of national identity, while simultaneously serving as a stage for political resistance by Black associations.

In the first experiment, seven treatments were evaluated in a completely randomized design, with eight replicates of 16 birds per experimental unit. Treatments included a basal control diet (meeting all nutritional requirements), a negative control diet with reductions of 0.15% calcium and phosphorus, 0.03% sodium, and 30 kcal kg⁻¹ of metabolizable energy, and five diets containing increasing phytase levels (500, 1000, 2000, 4000, and 8000 FTU/kg) added to the negative control. In the second experiment, seven treatments were evaluated in a completely randomized design, with six replicates of 16 birds per experimental unit. Treatments consisted of a diet deficient in available P, three levels of dicalcium phosphate supplementation (0.09%, 0.18%, and 0.27% available P), and three phytase supplementation levels (600, 1200, and 2400 FTU). In the third experiment, nine treatments were evaluated in a completely randomized design, with 10 replicates of 22 birds per experimental unit. Treatments included a positive control diet (minimum crude protein level), two negative controls (with reductions of 2% and 4% digestible amino acids, 0.15% calcium and phosphorus, and 15 kcal kg⁻¹ of metabolizable energy), and three phytase levels (500, 1000, and 2000 FTU/kg) applied to each negative control. Zootechnical performance and feed intake were recorded at 21 and 42 days in all three experiments. For intestinal histomorphometry, jejunal samples were collected at 21 and 42 days in the first experiment, and duodenal and jejunal samples at 21 and 43 days in the third experiment. Blood samples were collected at 21 and 42 days in the first experiment and at 35 days in the third, for analysis of biochemical parameters and enzymatic activity. Thigh samples were collected at 21 and 42 days in the first and second experiments to assess bone parameters. In the first experiment, a metabolism assay was carried out to evaluate the apparent digestibility of calcium, phosphorus, and metabolizable energy, and litter quality was analyzed at 40 days. In the third experiment, ileal content was collected at 21 days, while cecal content was collected at 21 and 35 days. Carcass yield was assessed at 42 and 43 days in the first and third experiments, respectively. In the first experiment, inclusion of up to 8000 FTU/kg of phytase maintained results similar to those of the positive control. In the second experiment, supplementation with up to 2400 FTU/kg increased the bioavailability of essential minerals, surpassing both deficient diets and diets supplemented with dicalcium phosphate, ensuring proper performance and bone development. In the third experiment, phytase improved performance and nutrient utilization in birds fed diets with reduced nutritional density, although doses above 1000 FTU/kg provided limited additional benefits.
