Interacção, emoção e aprendizagem

Mestrado em Multimédia em EducaçãoO presente trabalho propõe uma abordagem aos sistemas multimédia educativos baseada na relação entre a aprendizagem, a interacção no contexto das interfaces gráficas e as emoções. Os produtos multimédia com finalidades educativas para crianças nem sempre fornecem um suporte válido para o desenvolvimento da criatividade, das capacidades (cognitivas, perceptivo-motoras e emocionais) e para a aquisição de conhecimento. De modo a cumprirem estas funções é necessário que esses produtos sejam desenvolvidos com vista à integração das necessidades, interesses e capacidades das crianças. Partindo dos pressupostos que interfaces com diferentes paradigmas e estilos de interacção produzem diferentes reacções emocionais nos utilizadores, e que essas reacções emocionais interferem na aprendizagem, este projecto procurou evidências desses pressupostos através de um estudo de caso para o qual foi desenvolvido e testado um sistema multimédia vocacionado para o ensino da História da Arte.The present work proposes an approach to multimedia educational systems based on the relationship between learning, interaction in the context of graphical interfaces and emotions. Educational multimedia systems, addressed for children, don’t always provide a valid support for the development of creativity, skills or knowledge acquisition. In order to fulfil these functions multimedia systems need to be developed aiming for the integration of children’s capacities and needs, as perceptive motor skills, cognitive and emotional skills. Assuming that interfaces with different paradigms and styles of interaction produce different emotional reactions in the users, and that these emotional responses interfere/interplay with learning, this project looked for evidences of this assumptions through a case study for which was developed and tested a multimedia system with a theme from Art History

N,N '-dimethyl-N,N '-dicyclohexylsuccinamide: A novel molecule for the separation and recovery of Pd(II) by liquid-liquid extraction

N,N'-dimethyl-N,N'-dicyclohexylsuccinamide (DMDCHSA) is investigated as a potential molecule for the liquid-liquid extraction of Pd(II) from chloride solutions for the first time. The effect of several parameters on Pd(II) extraction, such as the contact period between both phases, hydrochloric acid, extractant and hydrogen ion concentrations, is evaluated. Pd(II) extraction equilibrium is very fast (30 s) and the extraction percentage (%E) increases with the HCI concentration in the aqueous phases, being higher than 60% for [HCl] > 5 M. The loading capacity of DMDCHSA for Pd(II) is reasonable (molar ratio extractant/metal higher than 16). Several stripping agents (e.g. distilled water, 1 M HCl, seawater and 20 g/L chloride solution as NaCl) were successfully used to transfer Pd(II) to a new aqueous phase, and data obtained from five successive extraction-stripping cycles suggest a good DMDCHSA stability pattern. Attempts to replace 1,2-dichloroethane (1,2-DCE) by commercial and more environmentally friendly diluents showed much worse %E for Pd(II). Selectivity tests with binary, ternary and more complex metal ion solutions were carried out to evaluate the performance of DMDCHSA towards Pd(II) recovery from 6 M HCl, when in presence of Pt(IV), Fe(III), Zn(II), Al(III) and Ce(III), metal ions usually present in solutions that may result from the hydrometallurgical treatment of spent automobile catalytic converters. It was generally observed that the additional metal ions do not affect the recovery of Pd(II) by DMDCHSA, although Fe(III) and Pt(IV) were co-extracted in a great extent. A solvent extraction (SX) scheme is proposed, based on a previous separation of Fe(III) with tributylphosphate (TBP) and on the selective and sequential stripping of Pt(IV) and Pd(II) from the loaded DMDCHSA with 0.01 M thiourea in 0.5 M HCI and seawater, respectively. The dependence of the Pd(II) distribution ratios on DMDCHSA and acidity, complemented with UV-Visible spectroscopy data, points out to DMDCHSA:Pd(II) extracted species with a 2:1 molar ratio and suggests the occurrence of an outer-sphere ion pair reaction, in which both [PdCl4](2-) and HCI are extracted

Uma nova reforma do ensino médio e as oportunidades educacionais: ponderações recentes / Una nueva reforma de la escuela secundaria y cómo las oportunidades educativas: consideraciones iniciales

Este artigo tem por objetivo apresentar, com base em uma investigação bibliográfica, reflexões iniciais de uma pesquisa de doutorado que analisa as implicações da nova reforma do Ensino Médio para a educação brasileira, sobretudo, para oferta dessa última etapa da Educação Básica. Nesse sentido, este trabalho faz uma análise a partir de autores, como Sfredo e Silva (2016) e Carrano (2017), que avaliam os impactos dessa e de outras reformas voltadas para essa etapa educacional, instauradas ao longo da história, que partiam de perspectivas semelhantes a atual proposta. Desse modo, é possível considerar a partir das discussões aqui levantadas, que a reformulação prescrita pela lei 13.415 reforça o processo de desigualdade educacional, ao mesmo tempo, em que intensifica a natureza e o caráter dual atribuído a essa etapa de ensino pelas diferentes políticas promulgadas no Brasil.

CULTURE MEDIA EVALUATION ON THE Leucoagaricus gongylophorus AND Escovopsis sp. FUNGI DEVELOPMENT

This study aimed to evaluate the in vitro interference of different culture media, Czapek Dox Agar, Nutrient Agar, Starch Casein agar, Malt Extract Broth Base, Nutrient Broth, and the medium containing Peptone, Malt, Agar and crushed peach palm pulp (Bactris gasipaes) and tucumã (Astrocaryum aculeatum) on the fungus Leucoagaricus gongylophorus and the parasitic fungus Escovopsis sp. growth. The fungi were inoculated in different culture media and then kept in acclimatized chambers at 28 ºC in the dark for 42 days, being analyzed at weekly intervals, totaling six evaluations. Fungal colonies were evaluated considering the factor "f" (cm), obtained from the product between the width (W) and length (L) of the diameter of the colonies (f = W x L). The results showed that the symbiotic fungus and the leafcutter ant parasitic fungus showed a growth increase compared to the media provided in the plates, and the media added with tucumã peel, tucumã peel+pulp, fresh peach palm, and cooked peach palm had a significant effect in the L. gongylophorus fungus development. However, these treatments were not promising for the Escovopsis sp. fungus compared to other culture media

O Centro de atenção psicossocial do Jardim América em Fortaleza e a desinstitucionalização: uma história de resistências

This article aims to discuss how mental health professionals understand the deinstitutionalization of asylums in Fortaleza, having as axis guiding the Brazilian Psychiatric Reform. The research that originated it was of a bibliographic, documentary and field. Systematic and participant observation, as well as the semi-structured interview with the professionals, enabled us to more often into the institution's universe. Among the main results we perceive the professionals' concern about the risk of an open service also institutionalize. They consider the formation of care networks to be essential in health, as a means of preventing deinstitutionalization from becoming a distant dream, and because many of the demands that came to the institution stem from "social problems" that could be addressed in the community.Este artigo objetiva discutir como os profissionais da saúde mentalentendem a desinstitucionalização manicomial em Fortaleza, tendo como eixonorteador a Reforma Psiquiátrica brasileira. A pesquisa que o originou foi de naturezabibliográfica, documental e de campo. A observação sistemática e a participante, assim como a entrevista semi-estruturada com os profissionais, nos possibilitaram adentrar mais amiúde no universo da instituição. Entre os principais resultados percebemos a preocupação dos profissionais quanto ao risco de um serviço dito aberto também institucionalizar. Eles consideram imprescindível a formação de redes de cuidado em saúde, como meio de evitar que a desinstitucionalização se transforme em um sonho distante, e em razão de que, muitas das demandas chegadas à instituição decorreriam de "problemas sociais", que poderiam ser atendidos na comunidade

Voltammetric growth of tin oxides in borate solution of pH 8.7

Voltammetry has been employed to study the growth of tin oxides in buffer solution of 0.3 mol L-1 H3BO3 + 0.15 mol L-1 Na2B4O7·10H2O (pH 8.7). Voltammetric data were compared with the results of tin in a phosphate solution of pH 8.7, presented in the previous work, in order to study the influence of these anions on the growth of tin oxides. The thicknesses of grown oxides were determined using ex-situ ellipsometric technique and the volume per charge unity of the film, Vf, was calculated for different charge densities of the film. The results showed that less dense films were obtained at higher sweep rates. Tin oxide films grown in phosphate solution at 2 mV s-1 were denser than those grown in borate solution at the same sweep rate. The kinetic parameters, determined applying the ohmic model, showed that there are no significant differences between the kinetics at the metal/film interface of tin in borate and tin in phosphate solutions. Despite these facts, the ionic specific resistivity for oxide film growth in borate solution were significantly higher than in phosphate solution. This result indicates that incorporation of anions occurs during the growth of the films
