Item type: Item , Avaliação formativo-dialógica na educação física nos anos iniciais do ensino fundamental: possibilidades no ensino da ginástica(Universidade Federal de Goiás, 2026-03-30) Santos, Lilian Pereira dos; Zanotto, Luana; http://lattes.cnpq.br/5835061445234248; https://orcid.org/0000-0003-1877-4170; Zanotto, Luana; http://lattes.cnpq.br/9718778267626503; https://orcid.org/0000-0003-1877-4170; Ferreira, Andreia Cristina Peixoto; http://lattes.cnpq.br/6904817595652410; Zandominegue, Bethânia Alves Costa; http://lattes.cnpq.br/7739333559051242; https://orcid.org/0000-0002-1106-3563This study investigates assessment in Physical Education in the early years of elementary school. The research problem consisted of investigating the possibilities of dialogical-formative assessment in this curricular component. The objective was to develop and analyze a methodological unit with the content of gymnastics, more specifically, Gymnastics for All (GFA), with the purpose of constructing possibilities for a dialogical and formative assessment. In a qualitative approach, as an initial step, the study sought to identify in the curricular guidelines and literature of Physical Education conceptions and orientations on assessment aimed at the early years of elementary school. In addition, the theoretical-methodological foundations of teaching gymnastics at this stage of schooling were systematized in order to support pedagogical practice. In the context of action research, the pedagogical proposal was developed during 16 Physical Education classes by the teacher-researcher with a 4th-grade class in a municipal public school in Caldas Novas/GO. The results evidenced the construction of evaluative possibilities of a dialogical, mediating, and processual nature. Teacher mediation, through continuous observation, attentive listening, pedagogical records, and intentional interventions, as well as the valuing of students' formative journey, constituted central axes of the evaluative movement. The investigated scenario reveals a permanent tension between discourses that defend formative and process-oriented evaluation and institutional demands still marked by classificatory and quantitative practices. The dialogical-formative perspective of evaluation in the treatment of Physical Education presented itself as a pedagogical possibility capable of favoring more inclusive, reflective, and humanizing processes, respecting the singularities of children and valuing Physical Education in school in its expressive, cultural, and collective dimension.Item type: Item , Harmony through alignment: unifying multimodal representations of sound and text across languages(Universidade Federal de Goiás, 2026-07-31) Ferreira, Alef Iury Siqueira; Avila, Sandra Eliza Fontes de; http://lattes.cnpq.br/8343699060914150; https://orcid.org/0000-0001-9068-938X; Silva, Nádia Félix Felipe da; http://lattes.cnpq.br/7864834001694765; https://orcid.org/0000-0002-3875-2211; Silva, Nádia Félix Felipe da; http://lattes.cnpq.br/7864834001694765; https://orcid.org/0000-0002-3875-2211; Berretta, Luciana de Oliveira; http://lattes.cnpq.br/0987947348533817; https://orcid.org/0000-0003-1857-8989; Candido Junior, Arnaldo; http://lattes.cnpq.br/8769928331729891; https://orcid.org/0000-0002-5647-0891The alignment of data modalities has achieved significant success, particularly in the text-image domain. However, extending these principles to create robust, multilingual representations of language and audio introduces distinct challenges that remain partially unaddressed in the literature. These include the scarcity of linguistically diverse text-audio datasets and the prohibitively high computing cost of training large-scale models. To address the high computational and data costs associated with multimodal expansion, this dissertation first introduces CACARA, a framework designed to integrate new modalities efficiently. CACARA employs an emergent alignment learning strategy. In our case, a new modality, audio, is aligned with a pre-trained and frozen multilingual image-text model. The model inherits the text encoder's rich multilingual capabilities by training our framework using only English data. This approach enables zero-shot cross-lingual and cross-modal retrieval, reducing training time and energy consumption. As a complementary contribution, this research presents PALMA (Pre-trained Audio-Language Multilingual Alignment via Mixture-of-Layers), a framework for the systematic design and optimization of bimodal language-audio models. PALMA goes beyond conventional methods by comprehensively evaluating state-of-the-art (SOTA) encoders and advanced training paradigms. Its central innovation is the “Mixture-of-Layers” (MoL) method. This learnable aggregation strategy fuses features from multiple encoder layers to create a richer, more nuanced audio representation. Empirical evaluations validate the proposed approaches, which achieve competitive results. Our findings give strong evidence that emergent alignment is a viable, scalable, and low-cost multimodal expansion strategy. This work contributes to the development of more accessible, efficient, and linguistically inclusive multimodal systems.Item type: Item , O tecido acrobático em Goiânia: mapeamento, caracterização e análise(Universidade Federal de Goiás, 2026-08-14) Siqueira, Fernanda Helena Vaz; Inácio , Humberto Luís de Deus; http://lattes.cnpq.br/4114148723699030; https://orcid.org/0000-0002-5683-7454; Neves, Ricardo Lira de Rezende; http://lattes.cnpq.br/5120704682457098; https://orcid.org/0000-0001-5357-8111; Bortoleto, Marco Antônio Coelho; http://lattes.cnpq.br/8517706988302686; https://orcid.org/0000-0003-4455-6732Esta disertación tuvo como objetivo analizar la configuración de la oferta de espacios para la práctica regular de tela acrobática (tecido acrobático) en Goiânia, considerando dimensiones geográficas, tipologías institucionales e infraestructura. Se realizó una investigación de métodos mixtos, descriptivoexploratoria, en dos etapas: un mapeo cuantitativo de los espacios que ofrecen clases regulares de la modalidad, seguido de entrevistas semiestructuradas con gestores y profesores, hasta alcanzar la saturación teórica. La investigación identificó doce espacios con oferta regular de tela acrobática, nueve de ellos con entrevista realizada, en distintas tipologías institucionales escuelas públicas de formación técnica, proyectos de circo social, compañías artísticas profesionales y estudios privados, evidenciando concentración espacial en barrios centrales y de clase media-alta. La infraestructura reveló variaciones de altura de techo, entre 3,5 y 10 6 metros, asociadas a una cultura consensuada de seguridad, con uso universal de colchones de alta densidad y supervisión constante. Se constató que la mensualidad cobrada por los espacios privados actúa como filtro socioeconómico, mientras que los proyectos gratuitos de circo social mitigan esa desigualdad, ampliando el acceso a la práctica. Se concluye que la tela acrobática se consolida, en Goiânia, como un campo potente y polisémico de las prácticas corporales de ocio, capaz de reconfigurar la relación de los sujetos con el cuerpo, el riesgo y la ciudad.Item type: Item , Dinâmica interfacial da transferência de massa de oxigênio: uma avaliação mecanicista entre surfactantes químicos e biossurfactantes em um canal hidráulico(Universidade Federal de Goiás, 2026-06-25) Oliveira, Luciano de; Formiga, Klebber Teodomiro Martins; http://lattes.cnpq.br/0787413754235970; https://orcid.org/0000-0003-1094-362X; Oliveira, Sérgio Botelho de; http://lattes.cnpq.br/3447406257464639; Ferreira, Murilo de Souza; http://lattes.cnpq.br/8611175932228788; Reis, Guilherme da Cruz dos; http://lattes.cnpq.br/0145327947923417; https://orcid.org/0000-0003-0034-0745; Basso, Raviel Eurico; http://lattes.cnpq.br/2827247646651873; https://orcid.org/0000-0002-5055-8470Oxygen mass transfer at the air-water interface, quantified by the k2, is the fundamental mechanism for the self-purification of aquatic ecosystems and the efficiency of sewage treatment processes. Historically, traditional k2 predictive models assume unrealistic hydrodynamic homogeneity and rely almost exclusively on macroscopic parameters, neglecting the physicochemical interactions imposed by surface contaminants. To bridge this gap, this research investigates the mechanistic influence of surfactants on the interfacial dynamics of oxygen transfer, comprehensively evaluating the interactive effect between the nature of the surfactant (chemical versus biological), its concentration, and the modulation driven by the liquid phase temperature. The study was structured along three main axes: initially, a systematic literature mapping highlighted the significant deficit of studies addressing biosurfactants under environmental conditions. Next, a full factorial experimental design was carried out in a recirculating hydraulic flume, evaluating chemical surfactants (SDS and LABSA) and ecological biosurfactants (RHEANCE® One and REWOFERM® SL ONE) at submicellar concentrations of 1 and 2 mg L-1, under isotherms of 20°C and 27°C. Finally, a physicochemical modeling approach supported by a zonal analysis was developed, challenging the use of hydrodynamic averages to assess the spatial decay of the flow. The results proved that adopting global averages masks the true interfacial physics. Through an analysis of covariance (ANCOVA), a highly significant interaction between temperature and concentration was found, revealing that temperature operates in the system as a “thermal switch”. It was observed that, at 20°C, increasing the surfactant concentration promoted an increase in k2, a phenomenon driven by the stabilization of “Marangoni Convection” cells that act as micro-stirrers in low-turbulence zones. In contrast, heating the fluid to 27°C triggered a drop in viscosity and accelerated the adsorption of a stagnant cap, activating the “Barrier Effect” and drastically collapsing k2 for all tested surfactants. Despite the general inhibition at high temperatures, biosurfactants demonstrated a significantly lower negative impact on oxygen transfer than chemical surfactants ones. This structural advantage stems from their “steric porosity”: the bulky hydrophilic heads of biological macromolecules undergo steric hindrance and prevent the dense packing of the monolayer at the interface, ensuring a superior residual permeability to oxygen that does not occur in the rigid films formed by the linear chains of chemical compounds. It is concluded, therefore, that the presence of surfactants, actively modulated by the thermal temperature of the medium, compromises the water reoxygenation capacity. The refinement of water quality models requires the immediate incorporation of rheological and spatial corrections to avoid the dangerous overestimation of self-purification and prevent the formation of hypoxic zones. In this scenario, biosurfactants emerge as a viable and strategic green chemistry technology, mitigating asphyxiation in water bodies and reducing the energy penalty in industrial aeration systems.Item type: Item , Economia circular e sustentabilidade: proposta de modelo diagnóstico de educação ambiental apresentada ao Tribunal de Justiça do Estado de Goiás(Universidade Federal de Goiás, 2026-07-02) Silva, Andréia Gomes da; Eliseu Vieira Machado Júnior; http://lattes.cnpq.br/8124167890774604; https://orcid.org/0000-0003-3829-2275; Araújo, Edna Torres; http://lattes.cnpq.br/1413586586523319; Carvalho, Claudia Regina Rosal; http://lattes.cnpq.br/4883069832734425; https://orcid.org/0000-0003-0913-9562Due to the exhaustion of the linear economic model and its increasing socio-environmental effects, this study seeks to examine how Environmental Education (EE) can be used as a tool to promote the Circular Economy (CE), assisting in the consolidation of sustainable practices and the strengthening of institutional policies in the context of the Court of Justice of the State of Goiás (TJGO). The central question guiding the study is: How can weaknesses regarding institutional support, communication flows, and public procurement governance within the daily operations of the Court of Justice of the State of Goiás (TJGO) be identified through an environmental education diagnosis, in order to guide the formulation of policies that implement sustainability and the transition to a circular economy, thereby narrowing the gap between theory and practice? The investigation is based on the understanding that the Circular Economy, by suggesting the regeneration of material and energy cycles, requires a paradigmatic shift in the forms of production, consumption, and institutional administration. This change is only achieved through the cultural transformation fostered by Environmental Education. Methodologically, a qualitative/quantitative, exploratory, and descriptive approach is adopted, structured in three stages: (i) bibliographic and documentary review on Circular Economy, Environmental Education, Sustainability, and Public Policies; (ii) application of structured questionnaires with a Likert scale to TJGO (Court of Justice of Goiás) employees, in order to assess perceptions, practices, and barriers to sustainability; and (iii) construction of a Diagnostic Model of Sustainability integrating principles of Circular Economy and Environmental Education. It is expected that the results will point to the integration between Environmental Education and Circular Economy capable of generating effective institutional change, by strengthening ecological awareness, optimizing resources, and inducing more sustainable management practices. It is concluded that the proposed model can serve as a strategic tool for TJGO and other public institutions, contributing to a more participatory, resilient environmental governance aligned with the contemporary challenges of sustainability.
