    This article aims to analyze the convergence between the evolution of federal investments in science, technology and innovation (STI) in Brazil as of 2002 and the agenda of the industry of the state of Santa Catarina for the ICT sector until 2022. Data were taken from the National Fund for Scientific and Technological Development (FNDCT) and the Industrial Development Plan of Santa Catarina (PDIC), specifically in the ICT sector. Combined practices of information technology and knowledge engineering were employed for the analysis. The study showed a mismatch between the federal and state agendas. Only a portion of the demands of the state were contemplated in the projects financed during the period of this study. There is therefore, a need to mature the institutional structure through mechanisms that allow different spheres to connect. The results show that approximately half of the resources are allocated directly to companies and half to higher education institutions, organizations of ICT and foundations. On one hand, these results suggest a balance between research that emphasizes the scientific and technological relevance and alignment with the principles of the systemic model of innovation. On the other hand, it reiterates the relevance of studies dedicated to investigating the process of university-company interactions in Brazil. Implications of findings on national STI policies are included in this study.This article aims to analyze the convergence between the evolution of federal investments in science, technology and innovation (STI) in Brazil as of 2002 and the agenda of the industry of the state of Santa Catarina for the ICT sector until 2022.

    Este artículo aborda conceptos relacionados a las artes visuales y su enseñanza, teniendo como foco las prácticas de las Organizaciones No-Gubernamentales y más específicamente, de la Asociación Catarinense para la Integración del Ciego- ACIC. Para el desarrollo de esta investigación, se presenta un levantamiento bibliográfico sobre los conceptos aquí discutidos, entre ellos el de Arte-Educación, además del análisis de las entrevistas realizadas con profesores que envuelven arte en sus clases en la ACIC. En esta etapa de la investigación, se analizan dos preguntas de un cuestionario semi-estructurado, referidas a lo que los profesores entienden por arte y de que forma lo utilizan en sus prácticas con los alumnos ciegos. En un primer momento pretendemos establecer relaciones entre lo que dicen los teóricos sobre la enseñanza de las artes y lo que piensan los profesores sobre sus prácticas envolviendo estas. Seguidamente y partiendo de una concepción sobre el arte, fundamentada en los teóricos aquí citados, pasamos para el análisis de las entrevistas realizadas en la ACIC. Como resultado, se percibe que, aunque el arte aparezca en otras prácticas docentes, está más presente en la enseñanza de técnicas de artesanado, hecho que no se caracteriza como arte-educación, teniendo en cuenta que aquella práctica no contempla los objetivos del arte-educación.This paper aims approach the concepts related to visual arts and their teaching, focusing on the practices of non-governmental organizations (NGOs) and, more specifically, of Santa Catarina Association for the Integration of the Blind – ACIC n order to develop this research, we present a literature review on the concepts discussed here, among them the one of Art-Education, along with the analysis of interviews with teachers who involve the art in their classes at ACIC. At this first stage of research, we examine two questions from a semi-structured questionnaire, which relate to what teachers mean by art and how they use it in their practice with blind students. In a first moment we intend, in this article, establish relationships between the theoretical says about the art education and what think the teachers about your practices involving these. After and starting a conception about the art, based in the theoretical cited here we pass for the analysis the interviews performed in ACIC As a result it is clear that, although the art appears in other teaching practices, it is more present in the teaching of techniques for craft, a fact that is not characterized as art-education, considering that practice does not include the goals in art-education

    TCC (graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Engenharia Civil.O aumento da frota de veículos no Brasil nos últimos anos vem agravando os problemas de mobilidade urbana dos grandes centros. Buscando reverter esses problemas, é necessário um planejamento urbano, avaliando diferentes alternativas para implantar novos sistemas ou aprimorar os existentes. Para esse planejamento, pode-se utilizar a técnica de simulação de tráfego. Este trabalho tem como objetivo principal elaborar e analisar um modelo de tráfego de um corredor urbano de uma área de estudo no município de São José utilizando a técnica de simulação de tráfego, realizando comparação do cenário atual com cenários alternativos com a projeção de demanda para o futuro. O modelo de tráfego foi elaborado utilizando software VISUM, em nível macroscópico, inserindo os dados de infraestrutura, controle de tráfego e demanda. As análises foram realizadas no software VISSIM, em nível microscópico, após realizar o recorte da área de estudo no VISUM e a sua exportação. A demanda atual foi projetada para o ano de 2029 e foi utilizada como demanda dos cenários alternativos. Foram analisados três cenários alternativos, para o primeiro cenário foi proposto o aumento no número de faixas de rolamento do corredor principal. Para o segundo cenário foi calculado o tempo de defasagem através do diagrama espaço-tempo. E o último cenário, foi elaborado sem alterações, somente com a demanda projetada. Foi realizada a análise comparativa entre os resultados dos três cenários alternativos. O cenário com o aumento no número de faixas de rolamento apresentou os melhores resultados, beneficiando a fluidez do tráfego. O cenário com o cálculo das defasagens e o sem alterações apresentaram resultados semelhantes, ficando o cenário com o cálculo das defasagens com resultados melhores.The increase in the number of vehicles in Brazil in recent years has aggravated the urban mobility problems of major centers. Seeking to reverse these problems, urban planning is needed, evaluating different alternatives for deploying new systems or enhancing existing ones. For this type of planning, one can use a traffic simulation technique. This work plans, as the main objective, to elaborate and analyze a traffic model of an urban corridor in a study area in the city of São José, using the traffic simulation technique, comparing the current scenario with alternative scenarios with the projection of future demand. The traffic model was developed using macroscopic VISUM software, entering the infrastructure, traffic control and demand data. The analyses were performed using VISSIM software, at microscopic level, after cutting the study area in VISUM and exporting it. Current demand was projected for the year 2029 and was used as the demand for alternative scenarios. Three alternative scenarios were analyzed, for the first scenario it an increase in the number of main aisle rolling lanes was proposed. For the second scenario, the lag time was calculated using a space-time diagram. The last scenario was elaborated without changes, only using projected demand. A comparative analysis was performed between the results of the three alternative scenarios. The first scenario, in which the number of lanes is increased shows the best results, benefiting the flow of traffic. The second and third scenarios showed similar results, with the calculation of time lags having better results

    Background: Maxillary osteotomy is typically undertaken to correct abnormal facial growth in cleft lip and palate. The surgery can cause velopharyngeal insufficiency resulting in hypernasality. This study aims to identify valid predictors of acquired velopharyngeal insufficiency following maxillary osteotomy by using a range of perceptual and instrumental speech investigations and multiple regression. / Methods: A prospective study was undertaken consisting of a consecutive series of patients with cleft lip and palate (N = 20) undergoing maxillary osteotomy by a single surgeon. Participants were seen at: 0 to 3 months pre-surgery (T1), 3-months (T2), and 12-months (T3) post-surgery. Hypernasality was rated using the cleft audit protocol for speech-augmented (CAPS-A) and visual analog scales, and nasalance was measured on the Nasometer II 6400. For lateral videofluorosopic and nasendoscopic images, visual perceptual ratings and quantitative ratiometric measurements were undertaken. Multiple regression analyses were undertaken to identify predictors. / Results: T3 models with hypernasality as the dependent variable were found to be a good fit and significant (eg, CAPS-A: R2 = 0.920, F(11,7) = 7.303, P = 0.007). Closure ratio (a quantitative ratiometric measurement) and proportion of palate contacting the posterior pharyngeal wall (a visual perceptual rating) were identified as significant predictors for the CAPS-A model (P = 0.030, P = 0.002)

    Objective: To investigate the effect of maxillary osteotomy on velopharyngeal function in cleft lip and palate (CLP) using instrumental measures. / Design: A prospective study. / Participants: A consecutive series of 20 patients with CLP undergoing maxillary osteotomy by a single surgeon were seen at 0 to 3 months presurgery (T1), 3 months (T2), and 12 months (T3) post-surgery. / Interventions: Nasalance was measured on the Nasometer II 6400. For videofluoroscopy and nasendoscopy data, visual perceptual ratings, for example, palatal lift angle (PLAn), and quantitative ratiometric measurements, for example, closure ratio (CRa), were made using a validated methodology and computer software. Reliability studies were undertaken for all instrumental measures. / Main Outcome Measures: Repeated measures analysis of variance (with time at 3 levels) for nasalance and each velar parameter. Planned comparisons across pairs of time points (T1-T2, T1-T3, and T2-T3) including effect sizes. / Results: A significant difference over time was found for nasalance (P = .001) and planned comparisons across pairs of time points were significant between T1 and T2 (P = .008), T1 and T3 (P = .002), but not between T2 and T3 (P = .459) providing evidence that maxillary osteotomy can impact on nasalance adversely and that the changes seen are permanent and stable. There were also significant differences over time for PLAn (P = .012) and CRa (P = −.059) and planned comparisons for both velar parameters reflected similar findings to those of nasalance. / Conclusions: Maxillary osteotomy can adversely affect velopharyngeal function in patients with CLP. The study provides evidence for a much earlier post-surgery review even as early as 3 months after surgery

    A Milstein scheme for SPDEs

    Get PDF
    This article studies an infinite dimensional analog of Milstein's scheme for finite dimensional stochastic ordinary differential equations (SODEs). The Milstein scheme is known to be impressively efficient for SODEs which fulfill a certain commutativity type condition. This article introduces the infinite dimensional analog of this commutativity type condition and observes that a certain class of semilinear stochastic partial differential equation (SPDEs) with multiplicative trace class noise naturally fulfills the resulting infinite dimensional commutativity condition. In particular, a suitable infinite dimensional analog of Milstein's algorithm can be simulated efficiently for such SPDEs and requires less computational operations and random variables than previously considered algorithms for simulating such SPDEs. The analysis is supported by numerical results for a stochastic heat equation and stochastic reaction diffusion equations showing signifficant computational savings.Comment: The article is slightly revised and shortened. In particular, some numerical simulations are remove
