Esta pesquisa verifica a opinião da criança por meio do desenho sobre o Lar de Longa Permanência para Idosos, antes e depois de contato lúdico com idosos institucionalizados. Para melhor caracterizar a população idosa, traça seu perfil neuropsicológico. Desenvolve-se junto a 21 idosos institucionalizados e 61 crianças com idades entre 7 e 12 anos, do Ensino Fundamental público. Inicia-se por verificar a opinião destas crianças sobre Asilo, por meio de desenho. Em seguida, realiza intervenção lúdica com crianças e idosos, de 10 encontros com brincadeiras simbólicas e jogos de regras. A seguir, reavalia a opinião das crianças e faz avaliação neuropsicológica dos idosos, por meio de Mini-Exame do Estado Mental, da Escala de Depressão Geriátrica, do Short-Form Health Survey (SF-36) e do Índice de Katz. Para verificar a opinião das crianças expressa por meio do desenho, utiliza de um título em aberto “Asilo é...”, a ser completado. Eles são analisados com subsídios do teste projetivo House-Tree-Person (HTP). Os resultados demonstram que houve, de uma aplicação para outra, alteração na opinião de 67% das crianças, que manifestaram opinião mais positiva relativa a perceber os idosos mais interativos e o Asilo mais humanizado, por meio de desenhos mais coloridas, de casas com portas e janelas, de pessoas sorrindo e em movimento e de mensagens afetuosas. Como aspectos negativos, encontram-se maior número de grades e de pessoas desenhadas sem face, o que pode representar a percepção da criança da dificuldade de contato do idoso com o mundo externo. Na análise estatística, encontrou-se média geral de 0,34 e desvio padrão de 0,16, no primeiro desenho e, no segundo, média de 0,42 e desvio padrão de 0,19, com médias obtidas numa escala de 0 a 1, em que se considera positivo o valor próximo a 1. Na avaliação neuropsicológica dos idosos, no MEEM, 50% demonstram preservação cognitiva. Os demais instrumentos indicam que a maior parte deles não apresenta sintomas depressivos, emite opinião positiva com relação à própria saúde, participa das atividades lúdicas e é dependente. Este estudo ressalta contudo que as características da instituição pesquisada, juntamente com a realização de atividades lúdicas, podem ter favorecido a opinião das crianças após seu contato com o Asilo. O estudo indica a necessidade de novas pesquisas sobre interação criança-idoso institucionalizado

Desde a sua origem que a Animação é utilizada como um meio de espelhar a sociedade através de técnicas e expressões que o cinema tradicional não permite. Ao incorporar a sátira na sua representação social e política está a expor uma crítica a características negativas com o intuito de alterar percepções e estereótipos, motivando a sua vulgarização ou correção. O projeto #LINGO consiste na realização de uma curta-metragem de animação com recurso à sátira, pretendendo incidir sobre um dos problemas em expansão no século XXI, a dependência nos dispositivos digitais e redes sociais.

Thin films of Co2FeAl (CFA) and trilayers with CFA/M/CFA, where M is Au or Ag, produced by magnetron sputtering onto glass and oriented (MgO (100)) substrates were investigated. The structural, magnetic static and magnetic dynamics properties were analyzed by distinct experimental techniques. Through X-ray diffraction was observed an A2 phase for the samples (completely disordered), where the atoms are randomly located in the lattice. The static magnetic behavior, in some samples, reveal a plateau behavior generated by a biphasic system. The magnetoimpedance measurements were performed by varying the angle between the external magnetic field and current with respect of anisotropy direction. For this reason, the MI results show a asymmetric magnetoimpedance (AMI) behavior. For the single and trilayers samples with 500 nm-thick, the AMI effect is more evident in comparison with samples with 1000 nm-thick. Therefore, in this work was stablished a route to produce Heusler alloy samples with A2 phase in thin film geometry onto amorphous and oriented substrates, and due to structural disorder was possible to study the hysteretic and MI asymmetric effects.

In recent decades, changes in the surface properties of materials have been used to improve their tribological characteristics. However, this improvement depends on the process, treatment time and, primarily, the thickness of this surface film layer. Physical vapor deposition (PVD) of titanium nitrate (TiN) has been used to increase the surface hardness of metallic materials. Thus, the aim of the present study was to propose a numerical-experimental method to assess the film thickness (l) of TiN deposited by PVD. To reach this objective, experimental results of hardness (H) assays were combined with a numerical simulation to study the behavior of this property as a function of maximum penetration depth of the indenter (hmax) into the film/substrate conjugate. Two methodologies were adopted to determine film thickness. The first consists of the numerical results of the H x hmax curve with the experimental curve obtained by the instrumental indentation test. This methodology was used successfully in a TiN-coated titanium (Ti) conjugate. A second strategy combined the numerical results of the Hv x hmax curve with Vickers experimental hardness data (Hv). This methodology was applied to a TiN-coated M2 tool steel conjugate. The mechanical properties of the materials studied were also determined in the present study. The thicknesses results obtained for the two conjugates were compatible with their experimental data.

The Nursing Homes are an important alternative care in the world, but Brazil still has no valid instrument to monitor the quality these institutions. In the United States, the Observable Indicators of Nursing Home Care Quality Instrument (OIQ) is used to assess the quality of Nursing Home care using 30 indicators of structure (2 dimensions) and process (5 dimensions) related to quality person-centered care. The present study aimed at cross-culturally adapting the OIQ in order to evaluate the quality of Nursing Home care in Brazil. Conceptual and item equivalence were determined to assess the relevance and viability of OIQ in the Brazilian context, using the Content Validity Index (CVI) and a group of specialists composed of 10 participants directly involved in the object of study. Next, operational, idiomatic and semantic equivalence were carried out concurrently. This consisted of 5 phases: (1) two translations and (2) their respective back translations; (3) formal appraisal of referential and general meaning; (4) review by a second group of specialists; (5) application of the pretest at three Nursing Homes by different social entities: health professionals, sanitary surveillance regulators and potential consumers. Measurement equivalence was evaluated by the Cronbach’s alpha test to verify the internal consistency of the instrument. To measure inter-evaluator agreement, the General Agreement Index (ICG) and Kappa coefficient were used. Timely compliance and 95% Confidence Interval of indicators, dimensions and total construct were estimated. The CVI obtained high results for both relevance (95.3%) and viability (94.3%) in the Brazilian context. With respect to referential meaning, similarity was observed, ranging between 90-100% for the first back translation and 70-100% for the second. In relation to general meaning, version 1 was better, classified as “unchanged” in 80% of the items, whereas in version 2 it was only 47%. In the pretest, the OIQ was easy to understand and apply. The following outcomes were obtained: a high Cronbach’s alpha (0.93), satisfactory ICG (75%) and substantial agreement between the pairs of evaluators (health professionals, regulators from the Superintendency of Sanitary Surveillance –SUVISA-, and potential consumers), according to the Kappa coefficient (0.65). It´s possible take the operational equivalence held since it preserved the original layout in the Brazilian version from the maintenance in application mode, response options, number of items, statements and scores. The performance of nursing homes obtained approximate average scores of 87, a variation 55-111 considering a range from 30 to 150 points. The worst outcomes were related to process indicators with a mean of 2.8 per item, while structure was 3.75 on a scale of 1 to 5. The lowest score was obtained for the care dimension (mean 2). The OIQ version was deemed to be a valid and reliable instrument in the Brazilian context. It is recommended that health professionals, regulators and potential consumers adopt it to access and monitor the quality of Nursing Home care and demonstrating opportunities for improvement.

Ferroelectric ceramics with perovskite structure (ABO3) are widely used in solid state memories (FeRAM’s and DRAM's) as well as multilayered capacitors, especially as a thin films. When doped with zirconium ions, BaTiO3-based materials form a solid solution known as barium zirconate titanate (BaTi1-xZrxO3). Also called BZT, this material can undergo significant changes in their electrical properties for a small variation of zirconium content in the crystal lattice. The present work is the study of the effects of deposition parameters of BaTi0,75Zr0,25O3 thin films by spin-coating method on their morphology and physical properties, through an experimental design of the Box-Behnken type. The resin used in the process has been synthesized by the polymeric precursor method (Pechini) and subsequently split into three portions each of which has its viscosity adjusted to 10, 20 and 30 mPa∙s by means of a rotary viscometer. The resins were then deposited on Pt/Ti/SiO2/Si substrates by spin-coating method on 15 different combinations of viscosity, spin speed (3000, 5500 and 8000 rpm) and the number of deposited layers (5, 8 and 11 layers) and then calcined at 800 ° C for 1 h. The phase composition of the films was analyzed by X-ray diffraction (XRD) and indexed with the JCPDS 36-0019. Surface morphology and grain size were observed by atomic force microscopy (AFM) indicating uniform films and average grain size around 40 nm. Images of the cross section of the films were obtained by scanning electron microscopy field emission (SEM-FEG), indicating very uniform thicknesses ranging from 140-700 nm between samples. Capacitance measurements were performed at room temperature using an impedance analyzer. The films presented dielectric constant values of 55-305 at 100kHz and low dielectric loss. The design indicated no significant interaction effects between the deposition parameters on the thickness of the films. The response surface methodology enabled better observes the simultaneous effect of variables.

This research focuses on the course of Guel Arraes, moviemaker, and picks two movies for analysis: O Auto da Compadecida (2000) and O Bem Amado (2010), as well as their costumes. The focus on the costume is based on Semiology and aims to decode the meanings that stem out of the clothes. Three of the movies characters will have their costumes analyzed based on Roland Barthes’ theory, mainly considering semiology elements (language and speech), (significant and meaning) and (system and syntagma). The influence of the Armorial movement into the movie O Auto da Compadecida and the Kitsch aesthetic in O Bem Amado deserve consideration, aside from the study on costumes function within narrative, supported by Roland Barthes’ structural analysis of the narrative. We sought to highlight the balance between characters’ lines and the image of the costumes in the movies. Adding to the study on how costumes strongly accounts to narrative, we observed characteristic traits of director and scriptwriter Guel Arraes present in his works, which are the northeastern man identity, a presentation of the Northeast and popular comedy. We believe that his choices when creating and his life influences are not separate from one another. Our research was movie-appraisal centered and had a thorough investigation all over language. The main considerations are supported by the following theories: Barthes (2007), Figueirôa and Fechine (2008), Moles (2001), Stuart Hall (2005) and Mikhail Bakhtin (2013).
