Item Técnicas preditivas para auxílio no diagnóstico de melanomas via imagens(2024-10-02) Silva Júnior, José Carlos Monte; Soares, Rodrigo Gabriel Ferreira; http://lattes.cnpq.br/2526739219416964Skin cancer is the most common type of cancer worldwide, divided into two main types: melanoma and non-melanoma. Although rarer, melanoma is the most lethal due to its potential to cause metastasis. Non-invasive methods, such as dermoscopy and the ABCDE rule, have been used to avoid unnecessary surgical procedures and have helped in the identification of lesions, contributing to faster diagnoses. With advances in technology, Artificial Intelligence (AI) has gained prominence, proving to be a promising solution for medical data analysis, especially with the use of Convolutional Neural Networks (CNNs), which can recognize patterns in dermoscopic images and help classify lesions as melanoma or non-melanoma in an automated manner. This project proposes an ensemble of classifiers based on Convolutional Neural Networks to classify dermoscopic images as melanoma or non-melanoma, comparing its performance with validated architectures, such as AlexNet and VGG-16, using Transfer Learning techniques The analyses of Precision, Recall, and F1 Score showed that the ensemble of Convolutional Neural Networks outperformed the models using Transfer Learning techniques, with AlexNet showing better performance than VGG-16. The ensemble of Convolutional Neural Networks demonstrated a greater generalization capability, proving to be promising in capturing relevant features from the images, revealing potential for medical applications, although it still needs refinement to meet clinical standards.Item Rastreabilidade na cadeia produtiva do atum (Thunnus sp.) comercializado fresco – revisão de literatura(2024-08-20) Alves, Adryanne Marjorie Souza Vitor; Moura, Andrea Paiva Botelho Lapenda de; http://lattes.cnpq.br/6414540974581675; http://lattes.cnpq.br/0158550024403180The Mandatory Supervised Internship is a required course in the 11th semester of the Veterinary Medicine Program at UFRPE, with a total workload of 420 hours.

Melanoma is a type of skin cancer that represents only 3% of cancer cases in the organ, but it is considered the most offensive due to high possibility of metastasis, which is the spread of cancer to other organs. Although melanoma is considered the main fatal skin disease, the introduction of new drugs combined with the detection of the tumor in early stages have contributed to positive prognosis. Through the ABCDEs rule of melanoma, it is possible to identify melanoma by watching some characteristics present in the lesion, however, the identification of melanoma through observation is often a failure, especially when it comes from an inexperienced doctor. Therefore, this work aims to select and use Machine Learning techniques to propose a model that can help dermatologists to identify skin lesions through dermoscopic images, serving as a second opinion to say if it is or it is not melanoma. The proposed model was compared with techniques widely used in the literature for solving complex problems, with the objective of presenting superior performance. Using Precision and Recall, the proposed model proved to be comparable to the others, although it had access to only 0,1% of the dimensions of the image, which indicates that the model worked well on finding the characteristics that discriminate skin lesions.Item Padronização do exame eletrocardiográfico em iguanas verdes (Iguana iguana)(2022-09-30) Cândido, Andressa Paloma Cavalcante; Costa, Fabiano Séllos; Reis, Afonso Cassa; http://lattes.cnpq.br/5648455698412892; http://lattes.cnpq.br/6876055943439186; http://lattes.cnpq.br/8549113588073479This work reports the activities carried out during the ESO (mandatory supervised internship), a mandatory subject for the completion of the Veterinary Medicine course at the Federal Rural University of Pernambuco.
