Atualmente, frente às desigualdades sociais e à emergência climática, não apenas contribuem na conquista de direitos, como também implementam novos arranjos socioprodutivos, mais sustentáveis e equitativos. Mesmo assim, é comum serem vítimas de violência de toda a ordem, em função dos preconceitos, estereótipos e do interesse do capital especulativo sobre os territórios. Face ao exposto, o artigo procura refletir sobre as especificidades e importância dos movimentos sociais, no Brasil, a sua capacidade de resiliência, e o papel da extensão no fortalecimento e difusão das inovações sociotécnicas surgidas no âmago dessas organizações. Para ilustrar, apresenta o Caso da Rede Ecovida de Agroecologia, fruto das demandas dos movimentos sociais, e o Movimento dos Trabalhadores Rurais Sem-Terra. A indissociabilidade entre ensino, pesquisa e extensão converge com a proposta de “regiões laboratórios”, em prol de uma transição referendada em uma nova base socioprodutiva, em que a sustentabilidade e a inclusão estejam no centro das ações.

Como parte do programa Latinpractice, iniciativa internacional de profissionais ligados à EDS/IEEE, o IFSC foi convidado para representar o Brasil e participar do projeto piloto de treinamento a estudantes para inserção na área de microeletrônica através do uso de ferramentas de projeto de circuito integrado de código aberto e de fabricação de chips VLSI. Para sua execução, houve uma etapa prévia de capacitação virtual de alunos tutores ministrada pela empresa TinyTapeout. Esses conhecimentos foram repassados em formato de acampamentos (bootcamps), onde o treinamento dos participantes era organizado em uma programação de um ou mais dias. O local de realização foi o câmpus Itajaí, onde um grupo de vinte alunos do curso de engenharia elétrica de diversas fases receberam o treinamento. Diferentes ideias de projeto foram desenvolvidas pelos times de alunos. Três projetos conseguiram ser submetidos à fabricação em setembro de 2023 na rodada de número quatro da TinyTapeout. Ao final do acampamento, houve uma avaliação positiva por parte dos participantes, manifestando também o desejo de participar em novos projetos relacionados à área e de treinamento no uso de ferramentas de descrição de hardware mais avançadas tais como Verilog. Como principais obstáculos, foram identificados a necessidade de conhecimento prévio e as limitações para escolha de portas lógicas no software Wokwi, e pouca experiência dos alunos com a sistematização para a realização de um sistema digital, e o tempo hábil para o desenvolvimento do projeto.

Este ensaio discute alguns elementos da relação entre movimentos sociais e institutos federais. Para tanto, são apresentados os conceitos de extensão universitária e de extensão tecnológica, retomando elementos históricos e experiências desenvolvidas em diferentes instituições. No texto também se discute alguns elementos de aproximação entre o conceito de extensão tecnológica e a prática dos movimentos sociais, cotejando elementos da legislação educacional com a bibliografia pertinente acerca do tema.
Viga prismática delgada e elástica: três aplicações de importância prática na engenharia
Authors: Araújo Jorge Corrêa de , Marquez Rosa Garcia
Published: December 2024

As vigas prismáticas submetidas à esforços, podem sofrer deformações elásticas. Nesse estudo, três aplicações envolvendo uma viga de aço prismática quase retilínea são analisadas. A primeira, consiste em uma carga concentrada P em seu ponto médio, onde a modelagem é tratada de duas formas distintas. Uma forma utiliza a equação do momento fletor com condições de contorno aplicadas em uma de suas extremidades e no ponto central da viga. Essa abordagem ficou em boa concordância com o modelo desenvolvido nesse estudo, onde as condições de contorno são aplicadas nos extremos da viga. Na segunda aplicação, uma mola é posta sob a barra no ponto médio, de modo a atenuar o movimento vertical causado pela força P. A elástica dessas deformações foi aqui determinada. A terceira aplicação consiste na disposição de três cargas equidistantes sobre a barra de modo a obter uma representação cinemática não forçada desse movimento.
Integrative Taxonomy of Wasps: Combining Morphological and Molecular Approaches of Indian wasps based on the COI gene sequencing (Hymenoptera: Vespidae)
Authors: Kandhasamy Mohankumar , M Suja
Published: December 2024

Five types of wasps are collected from the farm and belong to the vespidae family. They are all similar in that they make paper nests and mud nests. However, they vary in size, shape and location. The number of eggs, larvae, pupae and adults in each nest collected was monitored. Adult’s behavior, field notes on the shape, location of the nests, humidity and temperature of the nest located place were complied, and the number of founders and subdominant females was reported. In this present study, morphological studies were revealed. We used a molecular marker (Mitochondrial COI) to identify the collected five wasp’s genus and species. DNA sequences vary between different species, and species can be identified with DNA sequence data. Currently, COI gene sequences are used as the main molecular identification tool for insects.
Climate Change Impacts on Healthcare Infrastructure in Fiji: A Systematic Quantitative Literature Review
Authors: Deweerdt Tom , Johnstone Kelly R. , Jones Natalie A. , Richards Russell , Dargusch Paul
Published: December 2024

Healthcare infrastructure in Fiji is undoubtedly vulnerable to climatic driver impacts. These impacts range from direct damages caused by extreme weather events to more diffuse impacts of changes in vector-borne diseases, causing pressure on local healthcare infrastructure. Climatic impacts also create vulnerabilities in infrastructure domains, such as human resources. This paper quantitatively and systematically reviews 25 empirical papers examining climate-induced risks, vulnerabilities, and impacts on the Fijian healthcare infrastructure and following PRISMA guidelines. Researchers published their findings in 21 journals, primarily in the fields of ecology and public health. A Systematic Quantitative Literature Review (SQLR) was conducted to assess the state of knowledge in the literature and address the research questions. The SQLR was chosen due to its rigorous and transparent approach, following PRISMA guidelines. A total of 457 studies were screened, and 25 studies were included in the review after exclusions and review. Nearly all articles (80%) were risk, vulnerability, or impact assessments, and the methods used were evenly distributed between quantitative and qualitative. Extreme weather events, including floods and tropical cyclones, were the focus of most papers (70%). In Fiji, coastal Viti Levu was the most studied location (56%). Most papers (68%) focus on climatic impacts on facilities and human resources. This review underscores the urgent need for additional research to enhance the resilience of Fiji's healthcare facilities. Based on the results of this systematic review, the scientific literature must test and review several climate resilience pathways.
Deep learning for parameter identification of nonlinear dynamical system driven by fractional Brownian motion
Authors: Hou Wentao , Ma Shaojuan
Published: December 2024

This paper presents a deep learning-based parameter identifier capable of jointly identifying all parameters of a nonlinear dynamical system driven with fractional Brownian motion (FBM). Firstly, a new parameter identifier (TBNN) is constructed by combining the advantages of transformer in dealing with long-term dependence and bidirectional long short-term memory (BiLSTM) in extracting local features. Next, FBM is introduced as the random effect in the nonlinear dynamical system, and three examples are provided to simulate the established system. Finally, the TBNN identifier is used to identify the parameters of the three systems individually and compares with the PENN identifier to verify its effectiveness. The results demonstrate that the proposed TBNN identifier can identify all parameters of the nonlinear dynamical system more quickly and accurately. Additionally, three advantages of the TBNN identifier are discussed, including the stability of parameter identification results, the rationality of sample size selection, and the advantages of TBNN network construction.
