Item Acesso aberto (Open Access) Estimativa da produção de uma lavoura através de imagens digitais capturadas por veículo aéreo não tripulado (VANT)(Universidade Federal do Pará, 2018-10-08) SEREJO, Gerson Lima; GOMES, Ana Claudia da Silva; http://lattes.cnpq.br/9898138854277399; SANTOS, Viviane Almeida dos; http://lattes.cnpq.br/1489376127395764The use of Unmanned Aerial Vehicles (UAV) is becoming an important accessible tool for small to medium sized agribusiness. Its application supports the execution of complex and laborious activities, as well as promotes new studies and challenges for the field to assist the farmer's decision making. The County of Tucuruí, in the State of Pará Brazil, is part of a region that concentrates a great amount of rural properties characterized by being of family agriculture. The objective of this work is to present an exploratory study for applying steps of Digital Image Processing (DIP) and Computational Vision (CV) in images captured by a UAV to obtain the quantification of cassava seedlings and, consequently, harvest of this crop in a farm of the county. The scientific contribution of this study corresponds to the results obtained from the application of 4 vegetation indices: ExG, ExR, (ExG-ExR) and MaxG. The MaxG index presented the best result, counting 91% of the seedlings, in the best case, with an accuracy of 70%. The ExR index was more appropriate for counting the seedlings in initial stages of germination. The index (ExG-ExR) allowed the estimation with unsupervised thresholding, which improves the development of CV systems for this purpose. The ExG index surprised us with the lowest performance for the studied context, counting 58% of the seedlings, in the worst case, with accuracy of 73%. As practical contributions to the farmer, this study made it possible to raise awareness of the importance of forecasting the harvest to better plan the negotiation of production, later plantings and the search for resources to increase the mechanized area of the crop. Further indepth research needs to be conducted to confirm these findings.Item Acesso aberto (Open Access) Um guia de requisitos de softwares educativos para mulheres(Universidade Federal do Pará, 2025-06-25) DIOGO, Carla Braga; SANTOS, Viviane Almeida dos; http://lattes.cnpq.br/1489376127395764Information and communication technologies (ICTs) have demonstrated a crucial role in enabling gender equality, and are also one of the goals of the United Nations (UN). This paper presents a guide of recommendations to guide developers in the process of specifying educational software for women, thus facilitating the gathering of requirements for this audience. The guide was created based on the Design Thinking approach and, through Empathy, used a technique based on Personas through a case study of self-employed women from the Tucuruí Lake Region. It is estimated that through the adoption of this guide there will be greater ease in defining requirements and incentive in the creation of educational applications for women.Item Acesso aberto (Open Access) Logificação: ambiente gamificado para auxiliar no ensino de lógica de programação em cursos de computação(Universidade Federal do Pará, 2025-02-06) CASTRO, Maria Beatriz de Oliveira; SANTOS, Viviane Almeida dos; http://lattes.cnpq.br/1489376127395764The discipline of Programming Logic requires innovative pedagogical approaches. This study presents LOGIFICATION, an environment gamified by adapting Moodle, which combines game elements with Piaget's theory of cognitive development to facilitate the assimilation and accommodation of knowledge. Using resources such as avatars, points and rankings, the system aims to motivate and engage students in learning. The research demonstrated good results, with greater motivation, engagement and performance in the experimental group, highlighting gamification integrated with a learning theory as a promising pedagogical strategy for the teaching of Programming Logic.Item Acesso aberto (Open Access) Ostara: uma arquitetura de referência para coleta de dados em campo(Universidade Federal do Pará, 2019) SOUZA, Marcos Felipe Ferreira Amazonas de; SANTOS, Viviane Almeida dos; http://lattes.cnpq.br/1489376127395764Data collection is an important and recurring process for decision making, which is present in different areas. In general, there are several solutions developed to aid field data collection activities. However, such solutions focus on solving specific problems, causing a lack of uniformity in relation to basic characteristics belonging to the domain of data collection. To supply the need for a domain knowledge repository this work proposed the development of a reference architecture (RA) that serves as a model for the construction of systems that bellong to the data collection domain model and the subdomain of mobile data collection.In order to elaborate the proposed reference architecture, the ProSA-RA process was used, this process helps the iterative and incremental development of reference architectures. This process is represented in four steps, which aim to structure the development of reference architectures. After the elaboration of RA using the ProSARA process, we tried to instantiate an architectural prototype to be able to evaluate execution-time qualities belonging to the proposed RA. The architectural prototype was modeled based on the business requirements of the "Banco de Germoplasma" project maintained by the Eletrobras Eletronorte Agency. This project seeks to maintain information regarding animal and botanic species of the Tucuruí - PA region. The instantiated and implemented architectural portion constitutes a tool for phenological monitoring of the botanical species of the project. The evaluation of the architectural prototype performed with the domain experts demonstrated runtime-related qualities such as performance, security, functionality and usability. However, the achievements of further evaluations to obtain quality metrics are necessary, such as the evaluation of development quality elements such as modifiability, portability, integrability and interoperability.
