Oceans cover 70% of the Earth’s surface, but most of them are unknown to humankind. This is the reason why underwater imaging is a valuable resource asset to Marine Science. Images are acquired with observing systems, e.g. autonomous underwater vehicles or underwater observatories, that presently transmit all the raw data to land stations. However, the transfer of such an amount of data could be challenging, considering the limited power supply and transmission bandwidth of these systems. In this paper, we discuss these aspects, and in particular how it is possible to couple Edge and Cloud computing for effective management of the full processing pipeline according to the Compute Continuum paradigmThis work was partially funded by the European Union - NextGenerationEU and by the Ministry of University and Research (MUR), National Recovery and Resilience Plan (PNNR), Mission 4, Component 2, Investment 1.5, project “RAISE - Robotics and AI for Socio-economic Empowerment” - (ECS00000035); The co-author Simone Marini is part of the critical mass of the RAISE Innovation Ecosystem.

Defesa : Curitiba, 08/11/2024Inclui referênciasResumo: O uso de tecnologias móveis durante a gravidez de alto risco traz a paciente ao centro do atendimento, permitindo autogestão e acesso facilitado as informações de saúde. Aplicar a técnica de clusterização para identificar grupos de gestantes que iniciam o pré-natal de alto risco em uma maternidade no sul do Brasil, buscando compreender sua percepção de saúde, a usabilidade de um aplicativo "assistente em saúde" e comparar os desfechos materno-fetais entre usuárias e não usuárias do aplicativo, pode nos ajudar a entender os perfis de pacientes que teriam maiores benefícios com o uso da mHealth. Este é um estudo observacional do tipo coorte longitudinal que abordou gestantes no momento de sua vinculação ao pré-natal de alto risco de um hospital público universitário do sul do Brasil, no período entre abril de 2022 e novembro de 2023. Foram excluídas do estudo gestantes que não possuíam um smartphone compatível para download do aplicativo, ou que não tinham acesso à internet. Conforme randomização sistemática, uma paciente era alocada no grupo aplicativo e outra no grupo controle. Todas responderam ao "Questionário de Inclusão" (Q1) e as alocadas para o grupo aplicativo foram orientadas a utilizar o aplicativo "assistente em saúde" para se preparar para a primeira consulta de pré-natal, que aconteceria em algumas semanas, quando responderiam o Questionário de Usabilidade de Aplicativos de Saúde (MAUQ), versão brasileira. Após o nascimento, foram avaliados 11 desfechos do binômio materno-fetal. Para análise estatística foram utilizados os testes t de Student, Mann-Whitney, teste exato de Fisher e o Quiquadrado. Para a determinação dos clusters foi realizada uma Análise de Agrupamento Hierárquica com o método de Ward e a medida de distância euclidiana quadrática. O estudo resultou em 111 gestantes, das quais 55 (49,5%) foram alocadas para o grupo "aplicativo" e 56 (50,5%) no grupo "controle". Das 55 gestantes que utilizaram o aplicativo, 21 (38,2%) demonstraram adesão, com uma média de 6,2 pontos no MAUQ. A clusterização considerou 110 gestantes e o dendrograma resultou em três clusters, que apresentam diversas diferenças significativas nos quesitos renda familiar, histórico em saúde, adesão medicamentosa e hábitos de vida. O cluster 2 apresentou a menor adesão ao aplicativo (p=0,081) e compareceram significativamente a menos consultas pré-natal (6,9 consultas) em comparação com os clusters 1 (10,3 consultas) e 3 (9,1 consultas - p=0,006). A cesariana foi mais frequente no cluster 3 (95,3%) em relação aos clusters 1 (27,9%) e 2 (20,8%), p < 0,001. A análise de clusters revelou diferentes perfis de gestantes, permitindo identificar grupos que se beneficiariam de abordagens personalizadas e intervenções digitais para melhoria da autoconsciência e dos desfechos gestacionais. O aplicativo "assistente em saúde" apresentou boa usabilidade neste contextoAbstract: The use of mobile technologies during high-risk pregnancy, placing patients at the center of care, affords them self-management and easier access to health information. Employing cluster analysis to classify groups of pregnant women beginning high-risk prenatal care at a maternity hospital in southern Brazil, with the aims of understanding their health perceptions, assessing the usability of a "health assistant" app, and comparing maternal-fetal outcomes between app users and non-users, can provide valuable insights into the patient profiles that may benefit most from mHealth interventions. This is an observational longitudinal cohort study that looked into clusters of high-risk pregnant women admitted to antenatal care at the maternity unit of a public university hospital in southern Brazil between April 2022 and November 2023. Pregnant women who did not have a compatible smartphone to download the app or who did not have internet access were excluded from the study. According to systematic randomization, one patient was allocated to the app group and the other to the control group. They all answered an inclusion questionnaire (Q1) and those in the app group were instructed to use the Health Assistant app to prepare for their first antenatal appointment, which would take place in a few weeks’ time, when they would answer the Brazilian version of the Mobile App Usability Questionnaire (MAUQ). After childbirth, 11 maternal-fetal outcomes were assessed. Student’s t-test, Mann-Whitney U test, Fisher’s exact test, and the chi-square test were used for statistical analysis. A hierarchical cluster analysis was performed using Ward’s method and the Euclidean squared distance measure. The sample contained 111 pregnant women, of whom 55 (49.5%) were allocated to the application group and 56 (50.5%) to the control group. Of the 55 pregnant women who used the app, 21 (38.2%) demonstrated adherence, with an average MAUQ score of 6.2. Clustering included 110 pregnant women, and the dendrogram resulted in three clusters, which show several significant differences in terms of family income, medical history, medication adherence, and lifestyle habits. Cluster 2 had the lowest adherence to the app (P=.081) and attended significantly fewer antenatal appointments (6.9 appointments) as compared with clusters 1 (10.3) and 3 (9.1; P=.006). Caesarean section was more frequent in cluster 3 (95.3%) as compared with clusters 1 (27.9%) and 2 (20.8%), P<.001. Cluster analysis, revealing different profiles of pregnant women, allowed us to identify groups that would benefit from personalized approaches and digital interventions to improve self-awareness and gestational outcomes. The Health Assistant app showed good usability in this contex
A proposta de um plano de carreiras baseado na gestão por competências no contexto da administração pública gerencial
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Sócio-Econômico, Programa de Pós-Graduação em Administração, FLorianópolis, 2014.O presente estudo é uma análise do fenômeno dos planos de carreira na perspectiva da gestão por competências, no contexto do modelo gerencial de administração pública. A pesquisa delineou-se como um estudo de caso descritivo acerca da proposta de um novo plano de carreiras elaborado pela empresa pública catarinense CIDASC no ano de 2013. A abordagem adotada foi o método fenomenológico-estruturalista, onde se procurou descrever o fenômeno dos planos de carreira em vistas de suas estruturas fundamentais no contexto do caso analisado. Os procedimentos de coleta de dados foram a pesquisa documental direta, bibliográfica e a observação direta intensiva. As análises apontaram que os planos de carreira compõem um fenômeno congruente com os conflitos presentes na administração pública. Pôde-se perceber que a gestão por competências pode tanto apoiar iniciativas de melhoria da eficiência administrativa, quanto favorecer os anseios dos servidores públicos por melhores carreiras, quando incorporada aos planos de carreira. Finalmente, ficou aparente que os planos de carreira, aliando aspectos gerenciais e princípios públicos, podem ser uma alternativa viável para a necessária desburocratização da administração pública, conciliando ganhos para a organização, para os empregados e para a sociedade de modo geral.Abstract : The present study is an analysis of the phenomenon of career paths from the perspective of competency management in the context of the New Public Management. The research was outlined as a descriptive case study about the proposal for a new career path prepared by CIDASC, a public company of State of Santa Catarina, in the year 2013 The approach adopted was the phenomenological-structuralist method, which was aimed to describe the phenomenon of career paths in view of their fundamental structures in the context of the case examined. The procedures for data collection were direct documentary research, bibliographical research and intensive direct observation. The analyzes showed that the career paths compose a coherent phenomenon with conflicts in public administration. It could be perceived that competency management can both support initiatives to improve administrative efficiency, as favoring the concerns of public servants for better careers, when incorporated into career paths. Finally, it became apparent that career paths, combining management aspects and public principles, can be a viable alternative to the necessary bureaucracy of public administration, combining gains for the organization, for employees and for society in general
O Pessimismo como um devir: uma poética dos anos oitenta
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2011Esta tese enseja a possibilidade de leitura das letras de música do rock brasileiro dos anos oitenta sob o viés de uma poética pessimista, entendendo esta segundo as prerrogativas estabelecidas por Arthur Schopenhauer em O mundo como vontade e representação. Para tal, letras de Cazuza, Renato Russo e Humberto Gessinger estão aqui circunscritas como corpus para, por meio desta proposição de interpretação, estabelecer sondagens que possibilitem visualizar em seus versos temas que seriam afins ao do pensamento pessimista do século XIX. Com este intuito, a tese usa como instrumento de análise a epistemologia que faz parte da proposta desconstrutivista de Mil Platôs, obra de Gilles Deleuze e Félix Guattari, dando ênfase ao emprego que estes autores fazem dos termos devir e agenciamento. É com o uso destes termos, então, que este trabalho enquadra as letras que estão aqui selecionadas, vendo-as como uma reterritorialização do pessimismo enquanto um devir no rock brasileiro da década de oitenta. Devir este possibilitado em função dos agenciamentos oriundos das rupturas políticas, econômicas e sociais que protagonizaram o contexto histórico do Brasil após o fim do regime militar. Imiscuídos por estes agenciamentos uma nova geração se aproximou de temas que em si engendram uma estética de desilusão, apatia e descrédito pelos sistemas ideológicos de outrora; e que seriam uma tangente pós-moderna da concepção pessimista de que a vida, malgrado os diferentes contextos históricos que a envolvem, não proporcionaria nada além de tédio e vãs expectativasThis thesis entails the readability of the Brazilian rock music lyrics from the eighties under the bias of a poetic pessimism, pursuant to the prerogatives established by Arthur Schopenhauer in The World as Will and Representation. To do so, through this proposition of interpretation, lyrics of Cazuza, Renato Russo and Humberto Gessinger are here circumscribed as corpus to establish soundings enabling the view through their verses, themes to be related to the pessimistic thought of the nineteenth century. To this end, the thesis uses as an analytical tool the epistemology that is part of the deconstructive proposal of Thousand Plateaus, the work of Gilles Deleuze and Felix Guattari, emphasizing the application of the terms becoming and agency that these authors make use of. It is with the use of these terms, then, that this paper frames the lyrics that are here selected, seeing them as a repossession of pessimism while a becoming in the Brazilian rock music of the eighties. Becoming, this being possible depending on the agencies originated from political, economic and social disruptions which have carried out the historical context of Brazil after the end of the military regime. Intruded by these agencies a new generation came up with issues that in itself engender an aesthetic of disillusionment, apathy and disbelief of the old ideological systems; and that would be a postmodern tangent of the pessimistic conception that life, despite the different historical contexts surrounding it, would provide nothing but boredom and vain expectations
Análise com base em córpus de expressões multipalavras com o verbo quedar(se) em dicionários da língua espanhola
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Estudos de Tradução, Florianópolis, 2014.O objetivo deste estudo é comparar o material de dois dicionários monolíngues de Língua Espanhola, considerados referência por professores e aprendizes: o dicionário eletrônico DRAE (Diccionario de la Real Academia Española) e o SALAMANCA (Diccionario Salamanca de la lengua española), em relação ao uso linguístico real. A investigação focaliza, primeiramente, as variações encontradas ao contrastar as definições de expressões multipalavras contendo as formas do verbo quedar(se) presentes em cada um dos dicionários mencionados. Além disso, estas definições são comparadas em relação às ocorrências destas expressões multipalavras extraídas de um córpus de textos da língua espanhola disponível em linha, o Corpus del español. Os parâmetros da análise são a suficiência e a eficácia das informações transmitidas ao consulente pelos dicionários, tendo em vista uma compreensão das referidas expressões multipalavra, sobretudo por estudantes do espanhol como língua estrangeira. Apesar de um dos dicionários investigados apresentar as expressões multipalavras de forma mais abrangente e esclarecedora, a maneira pela qual as referidas expressões são tratadas pelos dois dicionários nem sempre corresponde ao uso real da língua.Abstract : The purpose of this study is to compare data from two monolingual Spanish language dictionaries, both of which are considered benchmarks by students and language teaching professionals: the electronic dictionary DRAE (Diccionario de la Real Academia Española) and SALAMANCA (Diccionario Salamanca de la lengua española), regarding actual language use. The investigation primarily focuses on the variations found by contrasting the definitions of multi-word expressions containing forms of the verb quedar(se) present in each of the aforementioned dictionaries. Furthermore, these definitions are compared regarding the occurrences of those multi-world expressions extracted from a corpus of Spanish language texts available online, the Corpus del español. The parameters for analysis are the sufficiency and efficacy of the information transmitted to the consultant by the dictionaries, aiming for comprehension of the previously mentioned multi-word expressions, especially by students of Spanish as a foreign language. Although one of the chosen dictionaries presents multi-word expressions in a comprehensive and detailed manner, the way said expressions are presented on both dictionaries not always relates to actual language use
Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone
No full textABSTRACT Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna. Between 2008 and 2013 we evaluated changes in species composition and diversity and in the structure of the woody vegetation of savanna physiognomies in the transition between the Cerrado and Amazon biomes that were fire free for 11 years. The physiognomies form a gradient from savanna woodland (Typical Cerrado - TC), to low woodland (Dense Cerrado - DC), to woodland (locally called Cerradão - CO). We hypothesise that: 1) the more open physiognomies (TC and DC) are more dynamic compared to the closed physiognomy (CO); and 2) in the absence of fire vegetation tends to become more forested. We found that: 1) TC was more dynamic (e.g. greater increases in richness, diversity, and abundance of plants and basal area) than CO and DC; 2) The three physiognomies experienced an increase in basal area and abundance of individuals, but only certain key species contributed to these increases. These results indicate that the open physiognomies were more dynamic than the closed physiognomies, and in the absence of fire the savanna physiognomies became more forested and accumulated biomass

Dynamics of the woody vegetation of two areas of Cerrado sensu stricto located on different substrates
No full textA diferença de substrato pode causar respostas distintas sobre a dinâmica da comunidade vegetal. O objetivo deste trabalho foi comparar os parâmetros florístico, estruturais e de dinâmica da vegetação entre áreas queimadas de cerrado típico (CT) e cerrado rupestre (CR) (presença de afloramentos rochosos) ao longo do tempo. Foram estabelecidas 10 parcelas (20 m × 50 m) em cada local. Todos os indivíduos com diâmetro ≥ 3 cm a 30 cm de altura acima do solo foram identificados e mediu-se o diâmetro do caule tanto em 2009 quanto em 2012, depois de uma queima acidental em 2008. As mudanças nos parâmetros florísticos não foram significativas entre o CT e CR. Entretanto, foram encontradas diferenças (p < 0,05) principalmente com relação aos parâmetros estruturais e de dinâmica, como densidade (CT = 1.523; CR = 2.171 ind.ha-1), área basal (CT = 8,70; CR = 13,00 m2.ha-1), taxa de recrutamento (CT = 24,35; CR= 15,14% ano-1; p = 0,01), ganho (CT = 8,58; CR= 3,58% ano-1; p = 0,02) e perda em área basal (CT = 3,88; CR= 2,45% ano-1). Essas diferenças enfatizam a necessidade de avaliar de forma diferenciada essas fisionomias para criação de futuras estratégias de conservação.Differences in substrates can provoke distinct responses in the dynamics of a plant community. We compared changes the floristic, structural and dynamic parameters of the woody vegetation between burned sites dominated by cerrado típico (CT) and cerrado rupestre (CR), which is characterized by the presence of rocky outcrops, over time. We set up 10 plots (20 m × 50 m) at each site. All individuals (diameter of ≥ 3 cm at 30 cm height above the ground) were identified in the two censuses (2009 and 2012) and measured (stem diameter), after an accidental fire in 2008. Changes in floristic parameters between the CT and CR were not significant. However, we found significant differences (p < 0.05) in structural and dynamic parameters, such as density (CT = 1,523; CR = 2,171 ind.ha-1), basal area (CT = 8.70; CR = 13.00 m2.ha-1), recruitment rates (CT = 24.35; CR = 15.14% year-1; p = 0.01), gain (CT = 8.58; CR= 3.58% year-1), and the loss rates of basal area (CT = 3.88; CR= 2.45% year-1). These differences emphasize the need for a differential evaluation of these sites for the development of effective conservation strategies
