Dissertação Acesso aberto Agricultura familiar no estado de Santa Catarina: avaliação dos impactos ambientais e de trabalho dos produtores de morangos(2019) Silva, Aline Santiago de Oliveira daBrazilian production covers at least seven Brazilian states, with emphasis on Minas Gerais, São Paulo, Rio Grande do Sul, Espírito Santo, Santa Catarina, Paraná, and the Federal District. The municipalities Catarinenses, Içara and Rancho Queimado stands out in the production of the Strawberries. This research was exploratory-descriptive, using bibliographical and field research, through the case study producers from the municipalities of Içara and Rancho Queimado. Two methodological tools were combined: the Leopold matrix for the application of environmental impact studies composed of indicators versus impact factors, which allowed assigning degree and impactimportance values for each item analyzed. And for the survey of the physical demands of the tasks imposed on workers in the production of strawberries, the scale of corporal discomfort, which aims to raise the producers' grievances during their working day and the OWAS method, which seeks to define the risks of illness in relation to to the postures adopted during the work activities and the cognitive requirements were obtained through in loco observations. This dissertation presented an innovative character, as it provided the combination of two theoretical-methodological environmental impacts and Ergonomics. The two approaches combined made it possible to elaborate the recommendations, which pointed out alternatives to the generated waste, such as reverse logistics, impacts on natural resources, proposing the insertion of renewable energies, reuse of water, and measures were indicated for questions concerning the conditions of work, health and safety of producers, examples that converge towards the expanded concept of sustainability, that is, taking into account the three pillars: social, environmental and economicDissertação Acesso aberto Impactos ambientais de efluentes de origem hospitalar em meio hídrico e proposta de tratamento por plasma não térmico(2020) Rambo, Adriano AndradeThe importance of hospitals and other institutional sets of health service providers is undoubtedly deserved and of utmost need in view of the diversity of possible or unknown complications as experienced with the virus of severe acute coronavirus respiratory syndrome 2 (SARS-CoV-2), which causes the current pandemic of COVID-19. During this period we can see that many countries and regions lack progress to serve the population in a dignified and humanized way. However, care for the environment should also be taken into account and pay attention, considering that the conditions in which the environment is directly or indirectly interferes with the health of the population and the same place that treats and cures, cannot be the same that promotes diseases. In this sense, this dissertation aimed to investigate the possible environmental impacts arising from hospital waste and effluents through a current literature review of the last five years, comprising 2015 to 2019, and described in the form of an article intended for the first chapter of the dissertation. After the basic research, as a result of this, we observed in several articles the concern, mainly, in effluents and wastewater with the release, detection and quantification of antibiotics as potential causes of environmental impacts, because they interfere in the acceleration and intensify antimicrobial resistance. Thus, in order to seek a solution to eliminate antibiotics in water, for the second chapter, in article format, we aimed to investigate the degradation of the antibiotic tetracycline hydrochloride in water, fortified, through the use of non-thermal plasma (PNT), which is a clean, advanced and easy-to-apply technology. The results showed that the PNT is efficient in the degradation of tetracycline hydrochloride, presenting reductions of 91.28%, 92.19% and 93.56% in 10, 15 and 30 min of treatment, respectively. Bacterial sensitivity tests showed that antibiotic activity was inhibited in solutions that received PNT treatment for 15 and 30 minutes. However, it is considered that there is a need to monitor wastewater and hospital effluents, because they are potential routes of contamination of water bodies and derived by antibiotics; and that there are ways to treat and improve the quality of hospital effluents; that antimicrobial resistance is an extremely serious global risk that compromises people's health and the ecosystem, and tends to get worse if measures are not primarily established by decision makers.Dissertação Acesso aberto Sustentabilidade nas instituições de ensino superior: um framework de autoavaliação progressiva para universidades comunitárias(2019) Mazon, SimoneA sustentabilidade é um termo comumente associado à questões relacionadas ao meio ambiente, no entanto, o conceito é mais amplo e diz respeito à ações que promovam o crescimento econômico e social, sem comprometer o bem estar das próximas gerações. A literatura relata inúmeras iniciativas das universidades ao redor do mundo no sentido de tornar a sustentabilidade o foco crítico no ensino, pesquisa, extensão e operações buscando maneiras inovadoras de avaliar e relatar este movimento. No Brasil, as universidades comunitárias ocupam um importante papel de descentralizar o ensino superior e tem relevância em termos de número de estudantes e de impacto econômico sobre os municípios. Neste sentido, esta dissertação teve o objetivo de apresentar a modelagem de um framework capaz de auxiliar as universidades comunitárias de Santa Catarina, sul do Brasil, na autoavaliação de sua maturidade em termos de sustentabilidade. A pesquisa iniciou com a análise dos Planos de Desenvolvimento Institucionais buscando entender como a sustentabilidade está presente nos objetivos e metas deste documento. Partindo disto, foi proposto um instrumento que pudesse auxiliar na autoavaliação de diversos aspectos relacionados às dimensões do conceito de sustentabilidade: social, econômica e ambiental. A base teórica para o desenvolvimento do instrumento foi a descrição das metodologias de ferramentas de avaliação de sustentabilidade consagradas e utilizadas por universidades internacionais, juntamente com a percepção e interpretação de gestores das universidades comunitárias catarinenses. O resultado desta construção foi um framework de autoavaliação progressiva que poderá capacitar as universidades comunitárias a coletar, registrar e relatar suas ações, tornando o processo de avaliação externo mais simplificado. Espera-se com esta pesquisa que as universidades comunitárias de Santa Catarina possam iniciar um caminho que as leve a estar entre as instituições de nível superior integralmente comprometidas com a sustentabilidade.
