    Considering the valuable environmental and cultural heritage existing in the world in the context of agribusiness, it is possible to highlight the role of ethno-zootechnics as an important new tool for understanding these values, the rescue and generational transmission of livestock knowledge are relevant. Given this, the objective was to understand the perception of milk producers from the Ethno-zootechnical perspective. Through a semi-structured script, questionnaires were carried out with 41 interviewees and representatives of dairy farms to register the relevance of basic cultural knowledge associating them with social, economic and social environmental development. Cluster analysis was carried out using the hierarchical method. It was concluded that part of the dairy farmers located in the Northwest region of Minas Gerais state, the man/animal relationship is important, with traits of affection and utility. The transmission of traditional knowledge of the dairy activity is important, and that they believe that scientific and traditional knowledge can be beneficial in rural activity.Considerando o valioso patrimônio ambiental e cultural existente no mundo no contexto do agronegócio, é possível destacar o papel da etnozootecnia como uma nova ferramenta importante para a compreensão desses valores, o resgate e a transmissão geracional do conhecimento pecuário são relevantes. Diante disso, objetivou-se compreender a percepção dos produtores de leite na perspectiva Etnozootécnica. Foram aplicados questionários, por meio de um roteiro semiestruturado, com 41 entrevistados, representantes de fazendas leiteiras para registrar a relevância dos conhecimentos culturais básicos associando-os ao desenvolvimento social, econômico e socioambiental. A partir dos dados coletados procedeu-se com análise de cluster foi realizada pelo método hierárquico. Concluiu-se que para parte dos produtores de leite localizados na região Noroeste de Minas, a relação homem/animal é importante, com traços de afeto e utilidade. A transmissão do conhecimento tradicional da atividade leiteira é importante, e que eles acreditam que o conhecimento científico e tradicional pode ser benéfico na atividade rural

    Image segmentation is one of the main resources in computer vision. Nowadays, this procedure can be made with high precision using Deep Learning, and this fact is important to applications of several research areas including medical image analysis. Image segmentation is currently applied to find tumors, bone defects and other elements that are crucial to achieve accurate diagnoses. The objective of the present work is to verify the influence of parameters variation on U-Net, a Deep Convolutional Neural Network with Deep Learning for biomedical image segmentation. The dataset was obtained from Kaggle website (www.kaggle.com) and contains 267 volumes of lung computed tomography scans, which are composed of the 2D images and their respective masks (ground truth). The dataset was subdivided in 80% of the volumes for training and 20% for testing. The results were evaluated using the Dice Similarity Coefficient as metric and the value 84% was the mean obtained for the testing set, applying the best parameters considered

    Ethno-zootechny and its relationship with traditional knowledge in family farming / A etnozootecnia e sua relação com os saberes tradicionais do agricultor familiar

    Ethno-zootechny is a contemporary science, an analytical instrument for rescuing knowledge and its relationship with society's culture. The work aimed to analyze the perception and understanding of rural family's livestock about the ethno-zootechny concepts in the social, economic, and environmental scope in the Northwest of Minas Gerais. To this end, research was conducted using a semi-structured script involving 50 farmers, representatives of rural producers' families during 2019. Subsequently, the data obtained were analyzed in the light of a statistical and descriptive approach to the results. A cluster analysis was performed by the hierarchical method using the Ward model. The results indicate that the interviewees feel devalued by society as producers, on the other hand, maintain that the current condition of cattle ranchers is related to the intangible elements: inheritance of property, way of life, tradition, and preservation of rural values. The research pointed out that the form of knowledge acquisition encompasses a traditional process of transmitting knowledge across generations. The survey demonstrates a low level of technical assistance in the interviewed properties. It is concluded that the main form of knowledge transmission is generational. There is a confrontation between the old and the modern because of inherited and acquired rationalities and resistance with the new production technologies in family production units in the Northwest of Minas Gerais

    Many family farmers use cooperativism as a tool to strengthen productive environments and envision productive diversification as an income generation strategy. This study analyzed the diversification project promoted by CAPUL in 2020, in the municipality of Arinos - MG, focusing on the production of free-range birds (Gallus gallus domesticus) to supply the demand for school meals and local commerce. The objective of this study was to analyze the economic and social impacts that the project generated in the lives of family farmers and elucidate the relevance of cooperativism for the promotion of productive diversification, as well as to highlight the detachments and obstacles that existed during the execution of the project. The self-administered questionnaire was used as the primary data source, considering a universe of 14 family farmers. The data were obtained through qualitative and quantitative instruments and were tabulated using the Microsoft Excel program. For descriptive statistical analysis of the results, a cluster analysis was used with the hierarchical method by the Ward model. It is concluded with this research that the project entitled Frango Caipirão CAPUL caused impacts on the lives of family farmers and that the cooperative, through its ATER actions, exerted influences on the social and economic reproduction of the participants of that study, contributing to the strengthening family farming. It is implied, therefore, that other actions in the same segment can use this master's dissertation as a guideline.Muitos agricultores familiares empregam o cooperativismo como uma ferramenta para o fortalecimento dos meios produtivos e vislumbram a diversificação produtiva como uma estratégia de geração de renda. Este estudo analisou o projeto de diversificação promovido pela CAPUL no ano de 2020, no município de Arinos – MG, com foco na produção de aves caipiras (Gallus domesticus) para abastecimento da demanda para alimentação escolar e comércio local. O objetivo desse estudo foi analisar os impactos econômicos e sociais que o projeto gerou na vida dos agricultores familiares e elucidar a relevância do cooperativismo para a promoção da diversificação produtiva, bem como evidenciar os desprendimentos e entraves que existiram durante a execução do projeto. Utilizou-se como fonte de dados primários o questionário autoaplicável, considerando um universo de 13 agricultores familiares. Os dados foram obtidos por meio de instrumentos de cunho qualitativo e quantitativo e foram tabulados por meio do programa Microsoft Excel, para análise estatística descritiva dos resultados utilizou-se uma análise de cluster com o método hierárquico pelo modelo Ward. Conclui-se com essa pesquisa, que o projeto intitulado Frango Caipirão CAPUL causou impactos na vida dos agricultores familiares e que a cooperativa por meio das suas ações de ATER exerceu influências no modo de reprodução social e econômica dos participantes do referido estudo, contribuindo para o fortalecimento da agricultura familiar. Implica-se, portanto, que outras ações do mesmo segmento podem utilizar este artigo como eixo norteador
