E-mail: patricia.ponciano@ufla.br   ABSTRACT: World production of pork has increased in recent years, and currently Brazil is the fourth largest producer. One of the major challenges in animal production systems is providing adequate thermal comfort. In the pork industry, the lactation area presents a peculiar environmental requirement: the lactating sows need to be cooled while the piglets need to be heated, requiring two distinct microenvironments. Thus the objective of this study was to evaluate the behavior of piglets using digital image analysis techniques, detecting the presence and calculating the time of the animals inside the shelter equipped with different types of heating system. The study was conducted during the summer of 2015, in a swine maternity, where four different heating systems were used: a) shelter equipped with 250 W infrared light (SALI); b) shelter equipped with heated concrete floor heating by means of solar water heater constructed with alternative materials (SASA); c) shelter equipped with heated concrete floor heating by conventional solar water heater (SASC) and d) retractor shelter equipped with thermal concrete floor heating by means of electric resistance (SAEL). During the study, the environmental variables were monitored inside the shelter. A sequence of images of the piglets was used to evaluate the behavior of the animals. The algorithm developed was able to detect the presence of the piglets, and thus reduce the time for manual analysis of video monitoring.   Keywords: Thermal comfort, swine, segmentation   AVALIAÇÃO DE COMPORTAMENTO DE LEITÕES UTILIZANDO PROCESSAMENTO DIGITAL DE IMAGENS   RESUMO: A produção mundial de carne suína vem crescendo nos últimos anos, sendo que atualmente o Brasil é o quarto maior produtor. Um dos grandes desafios na produção é o conforto térmico dos animais. Na suinocultura, a maternidade é onde encontra-se o maior problema, pois a porca necessita ser resfriada e o leitão aquecido, necessitando de dois microambientes diferentes. Objetivou-se com o presente trabalho, avaliar o comportamento de leitões por meio da análise de imagem, detectando a presença e calculando o tempo de permanência dos animais dentro do abrigo escamoteador equipado com diferentes tipos de sistema de aquecimento. Todo o estudo foi conduzido durante o período de verão de 2015, numa maternidade de suínos, onde instalou-se quatro diferentes sistemas de aquecimento: a) abrigo escamoteador equipado com lâmpada infravermelho de 250 W (SALI); b) abrigo escamoteador equipado com piso térmico de concreto aquecido por meio de tubos de água quente construído com materiais alternativos (SASA); c) abrigo escamoteador equipado com piso térmico de concreto aquecido por meio de tubos de água quente convencional (SASC) e d) abrigo escamoteador equipado com piso térmico de concreto aquecido por meio de resistência elétrica (SAEL). Durante o estudo, foram monitoradas as variáveis ambientais no interno ao abrigo escamoteador. Para avaliar o comportamento dos animais foram utilizadas a técnicas de processamento de uma sequência de imagens dos leitões. O método de avaliação por imagens digitais mostrou-se viável na avaliação do comportamento dos leitões, diminuindo o tempo de análise manual da monitoração por vídeo.   Palavras-chaves: conforto animal, suíno, segmentação de imagem

    Abstract: A partir da década de noventa, em esfera nacional e internacional, a inclusão em educação se fortalece com inúmeras Políticas públicas educacionais que fundamentam a tríade: acesso, permanência e sucesso escolar. Para isso, os sistemas de ensino precisam se (re) organizar para a consolidação de espaços democráticos. Nessa perspectiva, vale o questionamento: será que todos desejam uma educação democrática? Assim, este estudo objetivou refletir/debater a escola e a sociedade à luz da Teoria Crítica, tendo como lente analítica o pensamento do filósofo Theodor Adorno, e de seus comentadores, de modo que problematizamos as amarras da sociedade, pois nos damos conta que a estrutura socioeconômica autoritária que vivemos obstaculiza a emancipação e, por conseguinte, a construção de escolas que celebrem as diferenças. Debruçando-nos sob tal ótica, percebemos que a inclusão em educação é a afirmação de um projeto educacional democrático, que reconhece as demandas específicas de cada estudante, trabalhando numa pedagogia onde a escola é quem deve adaptar-se ao estudante e nunca o inverso.

    Abstract: Este artigo tem como objeto de investigação o Plano Municipal de Educação de Itaguaí/RJ, que foi reformulado no ano de 2015, com validade até o ano de 2025. Para tal, tomando conhecimento da relevância do PME (2015) de Itaguaí, no que se refere a (re)orientação da educação do Município, este estudo teve como objetivo pesquisar/problematizar qual (re)orientação inclusiva está instituída para o atendimento pedagógico e educacional dos estudantes público-alvo da Educação Especial do Município. Neste sentido, como procedimento metodológico realizamos análise documental que consistiu na reflexão acerca do vigente Plano Municipal de Educação de Itaguaí. A concepção metodológica desta pesquisa se fundamenta na indissociabilidade entre teoria e método posta na Teoria Crítica da educação. O pensamento de Theodor Adorno subsidiou nossas análises, assim como as reflexões de Damasceno e Costa, comentadores de seu pensamento. Identificamos que o PME (2015) representa uma significativa conquista para a educação do Município, pois apresenta disposições político-pedagógicas que colaboram com a inclusão escolar de estudantes público-alvo da Educação Especial. Assim, torna-se urgente que o instituído no PME (2015) se implemente na esfera instituinte dos movimentos democráticos desta rede de ensino.

    Abstract: The present work aims to develop a mathematical model, based on fuzzy set theory, for predicting performance and the physiological responses of piglets raised in the farrowing house with different solar heating systems. To do this, a solar heater prototype was constructed using alternative materials and the heating efficiency was compared with a commercial solar heater system. In order to thermally evaluate the heaters, temperature sensors were installed in the inlet and outlet pipes of each floor and thermal reservoir. The fuzzy system was developed and the variables dry air bulb temperature (Tbs) and relative humidity (RH) of the air were defined as inputs. Based on the input variables, the fuzzy system predicts the productive performance (weight gain - WG) and physiological responses (respiratory rate - RR, rectal temperature –RT, and skin temperature - ST) of piglets raised in an environment with solar heating. Based on the results, the fuzzy model was adequate for predicting the physiological responses and productive performance of piglets, presenting low standard deviation and high correlation with the validation data. This model can be used to assist producers in decision making, especially regarding maintaining animal welfare while the thermal environment changes.

    Abstract: The Philadelphia (Ph+) chromosome, t(9;22)(q34;q11.2), originates from a chimeric gene called BCR-ABL and is present in more than 90% of CML patients. Most patients with CML express the protein p210 BCR-ABL and, with a frequency lower than 5%, express rare isoforms, the main one being p190. In the transition from the chronic phase to the blast phase (BP), additional chromosomal abnormalities, such as the presence of the double Ph+ chromosome, are revealed. Of the 1132 patients analyzed via molecular biology in this study, two patients (0.17%) showed the co-expression of the p210 and p190 isoforms for the BCR-ABL transcript, with the concomitant presence of a double Ph+ chromosome, which was observed via conventional cytogenetics and confirmed by fluorescent in situ hybridization. The BCR-ABL/ABL% p210 and p190 ratio increased in these two patients from diagnosis to progression to blast crisis. To our knowledge, this is the first report in the literature of patients who co-expressed the two main BCR-ABL transcript isoforms and concomitantly presented Ph+ chromosome duplication. The evolution from the chronic phase to BP often occurs within 5 to 7 years, and, in this study, the evolution to BP was earlier, since disease-free survival was on average 4.5 months and overall survival was on average 9.5 months. The presence of the p190 transcript and the double Ph+ chromosome in CML may be related to the vertiginous progression of the disease.

    Abstract: The objective of this study was to evaluate the main scientific studies addressing the topic of compost barns in recent years, highlighting the main journals, authors, countries, organizations, and keywords associated with the publications and trends in this type of research through a bibliometric analysis. For this analysis, publications (articles and literature reviews) addressing compost barns were obtained from the Scopus and Web of Science databases. A total of 108 studies published between 2007 and April 2022 were included. A greater number of publications was observed starting in 2017, with 2021 having the largest number of publications. The Journal of Dairy Science was the most highly cited journal. Marcia I. Endres was the author with the greatest academic impact. The most influential country was the United States, followed by Brazil. Among the organizations that have published studies on compost barns, the Federal University of Lavras, and the University of Florence had the largest numbers of publications. In conclusion, this bibliometric analysis allowed us to evaluate the scientific evolution, research, and publishing tendencies of studies on the compost barn animal housing system, and the results make it possible to deduce current trends in scientific research and publications.

    Abstract: The compost barn system has become popular in recent years for providing greater animal well-being and quality of life, favoring productivity and longevity. With the increase in the use of compost barn in dairy farms, studies related to the thermal environment and behavior are of paramount importance to assess the well-being of animals and improve management, if necessary. This work aimed to characterize the thermal environment inside a compost barn during the four seasons of a year and to evaluate the standing and lying behavior of the cows through images. The experiment was carried out during March (summer), June (autumn), August (winter), and November (spring). Dry bulb temperature (tdb, °C), dew point temperature (tdp, °C), and relative humidity (RH,%) data were collected every 10 minutes during all analyzed days, and the temperature and humidity index (THI) was subsequently calculated. In order to analyze the behavior of the cows, filming of the barn interior was carried out during the evaluated days. Subsequently, these films were analyzed visually, and in an automated way to evaluate the behavior of these animals. For the automated analysis, an algorithm was developed using artificial intelligence tools, YOLOv3, so that the evaluation process could be automated and fast. It was observed that during the experimental period, the highest mean values of THI were observed during the afternoon and the autumn. The animals’ preference to lie down on the bed for most of the day was verified. It was observed that the algorithm was able to detect cow behavior (lying down or standing). It can be concluded that the behavior of the cows was defined, and the artificial intelligence was successfully applied and can be recommended for such use.
