Eucalyptus diameter and volume prediction with deep neural networks: a long short-term memory model approach
(2025-05) Rodrigues, Welington Galvão; Vieira, Gabriel da Silva; Cabacinha, Christian Dias; Soares, Fabrízzio Alphonsus Alves de Melo Nunes
Effective management of forest resources is vital for forestry companies. Accurate information is essential for planning planted forests. Therefore, forest inventory is a necessary procedure for obtaining quantitative and qualitative information about a region. Total volume serves as a critical metric for evaluating the potential of a specific area. This study presents an approach for modeling and forecasting diameters and total volume in planted forests. Diameter data at different tree heights in three different forest sites were used, and five neural network models were developed to estimate diameters and calculate volumes of eucalyptus clones. The models underwent training and testing using cross-validation techniques and were compared to statistical models. The results showed that the models based on Long Short-Term Memory (LSTM) are superiors. The LSTM models generalized tree volumes from diverse forest sites with greater accuracy than statistical models, even without site-specific training data. The percentage differences between the cubed volumes at sites (I, II, and III) and the volumes obtained by LSTM were smaller (0.01%, 1.06%, and 0.42%) in comparison to statistical models (0.35%, 1.81%, and 0.17%). These results highlight the potential of LSTM networks to provide accurate, generalizable, and non-invasive solutions for forest volume estimation, offering significant benefits for forestry management and decision-making.
A pesquisa escolar no ensino médio: análise da produção acadêmica no Brasil
(Universidade Federal de Goiás, 2025-03-21) Pimentel, Fernanda Cruvinel; Frazão, Sheila Cristina
The objective of this work is to investigate and analyze the academic production that addresses the theme of school research in high school. A bibliographic research was carried out using the keywords [school research + high school], in the temporal delimitation from 2009 to 2019. The analysis of the data collected leads us to understand the existing challenges to consolidate research as an effective pedagogical practice in school. The correlation between teacher, librarian and student in the school research process stands out in view of the difficulties encountered by these agents. The results indicate that it is essential to: qualify the training of teachers for the orientation of the research; intensify the integration between librarian and teacher with the support of the school library; and provide students with the development of skills to seek and use information in order to conduct their research. It is understood that there is a long way to go to achieve more comprehensive results regarding the importance of school research in Brazilian high schools.
A pupillary image dataset: 10,000 annotated and 258,790 non-annotated images of patients with glaucoma, diabetes, and subjects influenced by alcohol, coupled with a segmentation performance evaluation
(2025-03) Camilo, Eduardo Nery Rossi; Paranhos Junior, Augusto; Pinheiro, Hedenir Monteiro; Costa, Ronaldo Martins da
The Pupillary Light Reflex (PLR) is the involuntary movement of the pupil adapting to lighting conditions. The measurement and qualification of this information have a broad impact in different fields. Thanks to technological advancements and algorithms, obtaining accurate and non-invasive records of pupillary movements is now possible, expanding practical applications. Visual attention tracking enables the development of solutions for Eye Tracking Marketing or Eye Gaze Marketing, optimized gaming interactions, drowsiness detection in drivers, and, more recently, diagnostic support applications. These advancements have been made possible by algorithms and publicly available datasets to improve these algorithms. However, it is important to note that most of these datasets only provide information from healthy individuals. This article introduces and publicly shares a diverse dataset with three distinct subsets: recordings of individuals who underwent supervised alcohol consumption, individuals diagnosed with type II diabetes mellitus, and individuals diagnosed with glaucoma in early, moderate, and severe stages. In addition to the data, to assist researchers aiming to conduct studies involving pupillary behavior, the study evaluates pupillary segmentation and eye-tracking algorithms, highlighting the superior accuracy of YOLOv7 in calculating pupillary diameter compared to classical approaches. By utilizing the proposed dataset, the research advances the field of pupilometry-based diagnostics, promoting reliability and effectiveness and indicating the most precise methods for pupillary segmentation.
Ser mulher-mãe-estagiária-sobrevivente: um relato de experiência sobre o estágio docente em língua francesa no ensino remoto emergencial
(Universidade Federal de Goiás, 2025-03-19) Oliveira, Sirlene Terezinha de; Santos, Jakelline Prado dos
Since the establishment of the state of health emergency due to the coronavirus pandemic, in March 2020, and the consequent adoption of Emergency Remote Education (ERE), all people involved in any teaching-learning process have had their pedagogical practices profoundly changed. Among the activities related to teaching are the training stages of degree courses, confronted with the distance format on an urgent basis. Therefore, the Internship 3 and 4 subjects of the Modern Languages: French course at the Faculty of Modern Languages (FL/UFG), for which the preparation of teaching materials, possible semi-registrations and the conception of a work plan to be held in the fourth and final semester, at the Center for Teaching and Research Applied to Education (CEPAE/UFG), underwent an intense metamorphosis. In this sense, between August 2020 and June 2021, it can be said that we built another CEPAE, another FL and another French Foreign Language Internship. Everyone in their place, literally, was compelled to rethink all the work of that school year for a completely new context, that of emergency remote teaching. It was even necessary to rethink what it means to be a teacher, what a school, a classroom or the teaching-learning phenomenon as a whole is. All this while we were surviving a pandemic, which accentuated the vulnerability of various groups of people, and playing our other social roles, such as being a mother, in this troubled scenario. But despite the numerous difficulties and challenges of this situation, we had a very productive year in the Stage 3 and 4 subjects. This work therefore has the important function of reporting some of these experiences, which forever transformed the lives and academic careers of those who survived to be able to tell these narratives.
Produção de comida: a CSA artigo quinto enquanto movimento de (Re)existência ao agrohidronegócio
(Universidade Federal de Goiás, 2025-04-20) Mendonça, Marcelo Rodrigues; Soares, Bárbara Victória da Silva
El artículo presenta la Comunidade que Sustenta a Agricultura (CSA) Artigo Quinto en Palmeiras de Goiás/GO como un movimiento de (Re)Existencia, concebido a partir de las actividades productivas y de comercialización que garantizan la producción de alimentos por campesinos asentados por la reforma agraria. La producción de alimentos de la CSA Artigo Quinto es relevante para la soberanía alimentaria e incorpora habilidades y conocimientos, prácticas socioculturales que espacializan nuevas territorialidades contrahegemónicas, en territorios hegemonizados por el agrohidronegocio. A través de una investigación cualitativa y cuantitativa, se realizaron búsquedas bibliográficas, trabajo de campo, observaciones y anotaciones sobre las acciones construidas por los pobladores en el CSA. En las últimas décadas, la modernización territorial hizo que las prácticas tradicionales se perdieran en medio del avance de las corporaciones capitalistas, bajo la mirada complaciente del Estado y, muchas veces, con abundantes recursos públicos. Finalmente, se observaron las prácticas entendidas como movimiento de (Re)Existencia que posibilitan la preservación ambiental, la nutrición alimentaria, la producción y comercialización de alimentos en circuitos cortos, asegurando trabajo, renta y la reproducción de la vida campesina.
