Título: AVALIAÇÃO DA CONFORMIDADE DE WEBSITES COM A LGPD E O GUIA DE COOKIES DA ANPD: UMA ANÁLISE EMPÍRICA DE EMPRESAS EM CATALÃO (GO) Autor(es): Martins Neto, Antônio Messias Primeiro Orientador: Rosa, Eduardo Castilho Abstract: This paper presents an empirical analysis of the compliance level of 180 company websites located in Catalão with the Brazilian General Data Protection Law (LGPD) and the National Data Protection Agency (ANPD) Cookie Guidelines. The study evaluates privacy policies, cookie consent mechanisms, transparency practices, and data subject rights implementation. The results reveal a low overall compliance rate (31,3%), with significant disparities among economic sectors. The findings highlight the challenges faced by small and medium-sized enterprises (SMEs) in implementing data protection requirements and suggest the need for educational and regulatory support in regional contexts.

Título: AFFORDANCES E A PERCEPÇÃO DE USO EM TECNOLOGIAS ASSISTIVAS: UMA ANÁLISE COMPARATIVA ENTRE AS VERSÕES MOBILE DOS APLICATIVOS HAND TALK E VLIBRAS SOB A ÓTICA DE GIBSON E NORMAN Autor(es): Santos, Stéfanny de Souza Freitas dos Primeiro Orientador: França, Vanessa Primeiro Membro da Banca: Cury, Lacordaire Kemel Pimenta Segundo Membro da Banca: Tristão, Tatielle Esteves de Araújo Abstract: The digital inclusion of the deaf community requires the availability of tools that overcome communicational barriers on mobile devices, ensuring not only functionality but also usability. This work proposes a comparative analysis between the mobile versions of the Hand Talk and VLibras applications, using James Gibson's concepts of Affordance and Donald Norman's Perception of Use as a theoretical basis. The central objective is to examine how the layout of visual elements and the behavior of 3D avatars guide interaction on touch screens. Through a qualitative approach, based on the method of direct systematic observation guided by the literature, the interaction flows and present cognitive obstacles (gulfs of execution and evaluation) were mapped. The results demonstrate that design strategies that directly expose functionalities on the interface reduce cognitive load, while minimalist approaches tend to hide affordances, requiring a greater effort for discovery. It is concluded that accessibility in assistive technologies depends intrinsically on semiotic clarity and the presence of explicit visual signifiers to consolidate user autonomy.

Título: COMPARAÇÃO DE MÉTODOS DE BALANCEAMENTO DE DADOS EM DIFERENTES CENÁRIOS Autor(es): Souto, José Antônio Ribeiro ; Sousa, Flavio Diniz de Primeiro Orientador: Costa, Nattane Primeiro Membro da Banca: Costa, Nattane Segundo Membro da Banca: Cardoso, Cristiane Terceiro Membro da Banca: Carvalho, Amaury Abstract: Class imbalance occurs when there is an unequal distribution among the classes in a dataset, such that one class has a significantly smaller number of instances compared to the others. This scenario represents one of the challenges present in machine learning tasks, directly impacting the performance of predictive models. This study aims to compare different data balancing techniques, including oversampling, undersampling, and hybrid approaches, applied to multiple datasets with different levels of imbalance. Experiments were conducted using classification algorithms such as Decision Tree (C5.0), Random Forest, Artificial Neural Networks (ANN), Logistic Regression, and SVM, which were evaluated using the following performance metrics: accuracy, precision, recall, and F1-score. The analysis of the results made it possible to identify the impact of balancing techniques in different experimental scenarios, as well as their limitations and advantages. In general, oversampling techniques frequently showed superior or equivalent performance compared to the other evaluated methods, while the use of unbalanced data tended to present inferior results for certain metrics and algorithms. In addition, tree-based models, such as Random Forest, demonstrated greater robustness across the different analyzed scenarios. The findings of this study aim to provide support for the appropriate selection of balancing methods, contributing to the development of more robust and reliable models.

Título: SISTEMA DE GERENCIAMENTO CENTRALIZADO DE BUFFETS E EVENTOS Autor(es): Faria, Ítalo Gonçalves Meireles ; Meireles, João Gabriel de Oliveira Primeiro Orientador: Cardoso, Cristiane de Fátima dos Santos Primeiro Membro da Banca: Costa, Nattane Luiza da Segundo Membro da Banca: Vieira, Gabriel da Silva Abstract: The management of buffets and events is still frequently carried out through decentralized processes, such as spreadsheets, messaging applications, and manual records, which may compromise information organization, hinder reservation tracking, and increase the occurrence of operational errors. In this context, this work presents the development of a mobile application for Android aimed at the centralized management of buffets and events, integrating the registration of food items and services, reservation control, and visual customization within a single environment. The adopted methodology included requirements gathering and analysis, definition of user profiles, and conceptual modeling using UML diagrams. The proposed solution employs a multi-tenant architecture, with the back-end implemented in Java using Spring Boot and services exposed through a RESTful API, while the front-end was developed with Angular, Ionic, and Capacitor. Among the implemented features are JWT-based authentication, management of food items and services, creation and approval of reservations with automatic event generation, and the sending of status notifications. As a result, a functional application was obtained that meets the defined requirements and centralizes, in a structured manner, the management processes of buffets and events within a single digital environment.
