Abstract This paper describes the Pacu Project innovation technologies during its trajectory related to aquaculture, as well as the impacts on its structure and dynamic. The research object is the Santa Rosa Farm production unit in Terenos, Mato Grosso do Sul. The influence of the interactive learning processes on the innovative act has been evaluated in this work. This case study uses the descriptive and explanatory methods used concerning the origin and dynamics of the company, through access to bibliographic and documentary sources, associated with data collection which was supported by a questionnaire applied to the executive manager, and visits to the unit. The research allowed the authors to verify the importance of the role played by interactive learning in the company, since its origins, be it either in processes of systemic innovation, as well as in the incorporation of competencies that enhance its resilience and the possibility of propagating knowledge systemically.

Resumo: Este artigo apresenta uma discussão sobre o atual modelo de desenvolvimento agrícola das terras cultivadas no estado de Mato Grosso do Sul. São discutidas as causas das transformações ambientais e os meios de produção que geram várias implicações sobre povos indígenas, agricultores familiares e biomas já fragilizados, além da questão da saúde humana e da segurança alimentar. Por fim, o artigo apresenta uma proposta, baseada em alternativas ecologicamente corretas, rumo à construção da sustentabilidade ambiental e do bem-estar social do estado de Mato Grosso do Sul.

Abstract: This paper presents a discussion about the current model of agricultural development of cultivated lands in the state of Mato Grosso do Sul. We discuss the causes of environmental transformations and the means of production that generate various implications on indigenous peoples, family farmers, and already fragile biomes, as well as the issue of human health and food safety. Finally, the article presents a proposal, based on ecologically correct alternatives, towards the construction of environmental sustainability and social welfare of the state of Mato Grosso do Sul.

Abstract The objective with this study was to analyze the body measurements of Girolando cattle, as well as measurements extracted from their images, to generate a model to understand which measures further explain the cattle body weight. Therefore, the experiment physically measured 34 Girolando cattle (two males and 32 females), for the following traits: heart girth (HGP), circumference of the abdomen, body length, occipito-ischial length, wither height, and hip height. In addition, images of the dorsum and the body lateral area of these animals allowed measurements of hip width (HWI), body length, tail distance to the neck, dorsum area (DAI), dorsum perimeter, wither height, hip height, body lateral area, perimeter of the lateral area, and rib height. The measurements extracted from the images were subjected to the stepwise regression method and regression-based machine learning algorithms. The HGp was the physical measure with stronger positive correlation with respect to body weight. In the stepwise method, the final model generated R² of 0.70 and RMSE of 42.52 kg and the equation: WEIGHT ( kg ) = 6.15421 * HW I ( cm ) + 0.01929 * DA I ( cm 2 ) + 70.8388. The linear regression and SVM algorithms obtained the best results, followed by discretization regression with random forests. The set of rules presented in this study can be recommended for estimating body weight in Girolando cattle, at a correlation coefficient of 0.71, by measurements of hip width and dorsum area, both extracted from cattle images.

This paper presents SCOT, a system for automatic theory construction in the domain of Graph Theory. Following on the footsteps of the programs ARE [9], HR [1] and Cyrano [6], concept discovery is modeled as search in a concept space. We propose a classification for discovery heuristics, which takes into account the main processes related to theory construction: concept construction, example production, example analysis, conjecture construction, and conjecture analysis.
