O risco de quedas pode ser reconhecido como fenômeno ou diagnóstico de enfermagem. Pesquisas relacionam diretamente isquemias miocárdicas, como a angina instável e o risco de cair. Objetivou-se analisar o diagnóstico de enfermagem Risco de quedas na ocorrência de angina instável por um estudo transversal realizado em 57 indivíduos internados em um hospitalescola, mediante exame físico e formulário. Para o tratamento estatístico foram utilizados teste qui-quadrado, teste exato de Fisher, Mann-Whitney, teste-t e Coefi ciente Phi (p<0,05). O Risco de quedas foi o diagnóstico de enfermagem mais prevalente (87,71%), sobretudo em homens, mais velhos, com menos anos de estudo e renda inferior. Presença da angina instável, hipertensão arterial, medicação anti-hipertensiva, doença vascular, difi culdades visuais e insônia apresentaram associação com o diagnóstico de enfermagem Risco de quedas. Conclui-se que é imprescindível o desenvolvimento de parâmetros claros e objetivos à mensuração mais acurada do risco de quedas no âmbito hospitalar

Tomámos a rubrica Diabruras de Nicolau, mais tarde Nicolau e Nicolina, do primeiro suplemento infantil de grande fôlego em Portugal – o Notícias Miudinho do Diário de Notícias, – e propusemo-nos criar cinco Livros- -de-Montar, um para cada fase do seu percurso, entre 1924 e 1933. Observámos o percurso das publicações infantis em Portugal, particularmente nas décadas dos nossos protagonistas, e tirámos ilações dos seus períodos áureos; pesquisámos suportes e mecanismos em papel recortado e todo o tipo de livros, no limiar do conceito. Tentámos perceber como poderíamos, sem recorrer a mão-de-obra estrangeira, criar livros pop-up em Portugal, a baixo custo, e contribuir para melhorar dois pontos fracos da cultura de hoje, que o nosso exercício na docência verifica diariamente: desenvolver competências ao nível da motricidade fina, perceção do espaço e gosto pela leitura; e fomentar momentos de partilha “analógica” entre gerações, cuja falta é hoje gritante; ABSTRACT: NICOLAU E NICOLINA, 90 years of pranks Taking as a starting Diabruras de Nicolau, later Nicolau e Nicolina, the first children’s supplement of grand success in Portugal – the Notícias Miudinho of Diario de Noticias, - we proposed to create five books to assemble, one for each phase of its course, between 1924 and 1933. We analysed the course of children’s publications in Portugal, particularly in the decades of our protagonists, taking conclusions of its golden periods; we searched for supports and mechanisms in cut paper and all kind of books, in the concept’s threshold. We tried to understand how we could create, without resorting to cheap labour from around the globe, pop-up books in Portugal, at low cost, and also to contribute to improving two weak points in today’s culture, that we as teachers face every day: to develop delicate motor skills, space perception and a taste for reading; and to encourage moments of analogical closeness between generations, whose absence is striking today.

Na poesia de Luiza Neto Jorge existe uma verdadeira poética do olhar, uma espécie de poder de encantação que permite o estabelecimento de nexos de continuidade com as artes visuais. Partindo desta premissa de base surrealista, pretende-se relacionar a poesia de Luiza Neto Jorge com a pintura, o cinema, a música, o teatro, a arquitetura e a escultura Nos ensaios poéticos do século XX, na criação do poema como matéria verbal, o papel da imagem passa a ser o de apresentar e não mais o de representar. Com base na definição de André Breton, a imagem contraria o conceito harmonioso de beleza tradicional, acasalando realidades contraditórias e adquirindo um caráter delirante, fantástico e até diabólico.

This work aims to investigate the historical narratives in which the graphic designer Alexandre Wollner assembled about the development of its own profession in Brazil, focusing the ways in which his discourse points relations among design (with greater emphasis in graphic design) and visual arts, the industrial development and notions about technology. Firstly, the theoretical setup searched for dialogues with design historians, with Mikhail Bakhtin, specially his concepts about “ideology” and “discourse’, and the theory of Field Autonomy by Pierre Bourdieu applied in the artistic practice. Following, the relation between Wollner’s own journey and the Brazilian industrial development is shown, and, at last, three of his historical texts are studied, which are written in different moments (1964; 1983; 1998), being those in which the analyzed author wished to point out the origens, events and names that are more remarkable. Throughout the work, it is pointed the importance of Wollner’s contact with the modernist european ideologies that share an abstract and rationalist matrix found at Hochschule für Gestaltung Ulm (HfG Ulm), the german design school from the city of Ulm, in the 1950s. Such modernist discourse understood the practice of design as a method with scientific character, being then different of some other more recurring artistic professional practices in some productive sectors. Wollner aimed to apply such ideals in his professional practice, being the foundation of the paulista office forminform, in 1958, one of his first expressions of such posture, and in his academic practice, helping the foundation of the Escola Superior de Desenho Industrial (ESDI), in Rio de Janeiro, in 1963. Such modernist ideals went along with moments of the Brazilian industrial development during the government of Juscelino Kubitschek (1956–1961) and the “Economical Miracle” from the military government (1968–1973). Wollner argued about the need for the development of national design as a technological and productive differential that would help the growth of national industry, based on Ulm’s project model concept. It is defended that Wollner’s professional and intelectual path, in his efforts of thinking a history of Brazilian design through the choice of pioneers in the area, was founded on an “ideal model” of design, leaving aside the modernist experiences from the 1950s. Such posture would indicate a search for validation of his own profession that was beginning to become more evident in Brazilian productive means, aiming the creation of a differential space in comparison with pre-established practices, usually link to graphic artists from the time.

Humans have a high ability to extract visual data information acquired by sight. Trought a learning process, which starts at birth and continues throughout life, image interpretation becomes almost instinctively. At a glance, one can easily describe a scene with reasonable precision, naming its main components. Usually, this is done by extracting low-level features such as edges, shapes and textures, and associanting them to high level meanings. In this way, a semantic description of the scene is done. An example of this, is the human capacity to recognize and describe other people physical and behavioral characteristics, or biometrics. Soft-biometrics also represents inherent characteristics of human body and behaviour, but do not allow unique person identification. Computer vision area aims to develop methods capable of performing visual interpretation with performance similar to humans. This thesis aims to propose computer vison methods which allows high level information extraction from images in the form of soft biometrics. This problem is approached in two ways, unsupervised and supervised learning methods. The first seeks to group images via an automatic feature extraction learning , using both convolution techniques, evolutionary computing and clustering. In this approach employed images contains faces and people. Second approach employs convolutional neural networks, which have the ability to operate on raw images, learning both feature extraction and classification processes. Here, images are classified according to gender and clothes, divided into upper and lower parts of human body. First approach, when tested with different image datasets obtained an accuracy of approximately 80% for faces and non-faces and 70% for people and non-person. The second tested using images and videos, obtained an accuracy of about 70% for gender, 80% to the upper clothes and 90% to lower clothes. The results of these case studies, show that proposed methods are promising, allowing the realization of automatic high level information image annotation. This opens possibilities for development of applications in diverse areas such as content-based image and video search and automatica video survaillance, reducing human effort in the task of manual annotation and monitoring.

Aims: To compare reading performance in children with and without visual function anomalies and identify the influence of abnormal visual function and other variables in reading ability. Methods: A cross-sectional study was carried in 110 children of school age (6-11 years) with Abnormal Visual Function (AVF) and 562 children with Normal Visual Function (NVF). An orthoptic assessment (visual acuity, ocular alignment, near point of convergence and accommodation, stereopsis and vergences) and autorefraction was carried out. Oral reading was analyzed (list of 34 words). Number of errors, accuracy (percentage of success) and reading speed (words per minute - wpm) were used as reading indicators. Sociodemographic information from parents (n=670) and teachers (n=34) was obtained. Results: Children with AVF had a higher number of errors (AVF=3.00 errors; NVF=1.00 errors; p<0.001), a lower accuracy (AVF=91.18%; NVF=97.06%; p<0.001) and reading speed (AVF=24.71 wpm; NVF=27.39 wpm; p=0.007). Reading speed in the 3rd school grade was not statistically different between the two groups (AVF=31.41 wpm; NVF=32.54 wpm; p=0.113). Children with uncorrected hyperopia (p=0.003) and astigmatism (p=0.019) had worst reading performance. Children in 2nd, 3rd, or 4th grades presented a lower risk of having reading impairment when compared with the 1st grade. Conclusion: Children with AVF had reading impairment in the first school grade. It seems that reading abilities have a wide variation and this disparity lessens in older children. The slow reading characteristics of the children with AVF are similar to dyslexic children, which suggest the need for an eye evaluation before classifying the children as dyslexic.

A interdisciplinaridade entre a música e as artes visuais tem sido explorado por conceituados teóricos e filósofos, embora não exista muito na área da interpretação visual do grafismo de partituras musicais. Este estudo investiga como os grafismos na notação e símbolos musicais afectam o intérprete na sua transformação em som, com referência especial a partituras contemporâneas, que utilizam notação menos convencional para a criação de uma interpretação por sugestão. Outras relações entre o som e o visual são exploradas, incluindo a sinestesia, a temporalidade e a relação entre obra de arte e público. O objectivo desta dissertação é a de constituir um estudo inovativo sobre partituras musicais contemporâneas, simultaneamente do ponto de vista musical e visual. Finalmente, também vai mais longe, incluindo desenhos da própria autora inspirados e motivados pela música. Estes já não cumprem uma função de notação convencional para o músico, embora existe uma constante possibilidade de uma reinterpretação. ABSTRACT; The inter-disciplinarity between music and visual art has been explored by leading theorists and philosophers, though very little exists in the area of the visual interpretation of graphic musical scores. This study looks at how the graphics of musical notation and symbols affect the performer in transforming them into sound, with particular reference to contemporary scores that use non¬conventional notation to create an interpretation through suggestion. Other sound-visual relationships are explored, including synaesthesia, temporality and the interconnection between work of art and audience or public. This dissertation aims to be an innovative study of contemporary musical scores, from a musical as well as visual perspective. Finally, it takes a step further with drawings of my own, directly inspired and motivated by the music. These no longer fulfil a conventionally notational function for the musician, yet the potential for a re-interpretation is ever-present.

O tema escolhido para este estudo, intitulado “Exploração do grafismo e da matéria expressiva da criança através de processos criados por artistas modernistas e contemporâneos”, pretende desenvolver alguns conceitos e investigar as várias metodologias artísticas relacionadas com a evolução gráfica, a matéria expressiva da criança e o experimentalismo nas expressões plásticas, explorando a matéria e a técnica. Para tal, enquadrou-se nesta proposta as teorias e métodos da Educação pela Arte e Educação Artística, no âmbito das nas Artes Plásticas, em particular na Educação Pré-Escolar. Teve-se a intenção de traçar um projeto de investigação prático direcionado a três grupos de jardim-de-infância, dos 3 aos 6 anos, em contexto escolar. Esta investigação tem como base notas de campo, entrevistas, fotografias, análise documental e de conteúdo. Pretendeu-se verificar através dos resultados da investigação teórica e prática que a introdução das Artes Visuais é uma mais-valia no contexto educacional, no sentido do estudo centrar-se na compreensão da evolução gráfica individual, seguindo o percurso de cada criança e o tempo das sessões) e a sua própria linguagem artística, pois através dela se pode analisar várias perspetivas: como as crianças produzem e aprendem a criar expressões plásticas – produção artística; qual a importância da expressão artística e da criatividade; bem como a aprendizagem dos conhecimentos empíricos das Artes Visuais através do processo de criação dos artistas, ensinando indiretamente à História da Arte. Consideramos relevante a inovação do ensino artístico na Educação Pré-Escolar através dos materiais não convencionais das artes plásticas, inspirados na “arte pobre”, isto é, empregar elementos naturais - como título de exemplo: a cortiça, folhas, ouriços das castanhas, areia da praia; as matérias da cozinha (papel de cozinha, chocolate, farinha, cereais, beterraba) e da higiene (espuma de barbear) e, por fim, os materiais reutilizáveis e recuperáveis como o cartão, tecidos, entre outros. Neste sentido, torna-se relevante entender que estas formas de linguagens artísticas permitem desenvolver determinadas capacidades da criança como ser criador, explorador, autêntico, capaz de expressar ideias e sentimentos recorrendo aos seus próprios códigos.

This work main objective is to study the use of bricks in barium X-rays rooms in order to contribute to the optimization of shielding rooms diagnosis. The work was based on experimental measurements of X-ray attenuation (40 to 150 kV), using ceramic seal bearing the incorporation of barium sulfat (BaSO4). Different formulations were studied in three different firing temperatures and evaluated for incorporation in the ceramic body. The composition of 20% of barite processed at a temperature of 950 ° C showed better physical and mechanical properties, is considered the most suitable for the purpose of this work. Were produced bricks sealing composition formulated based on that presented the best technological features. These blocks were tested physically as a building material and wall protective barrier. Properties such as visual, deviation from the square, face flatness, water absorption and compressive strength were evaluated for all the blocks produced. The behavior of this material as attenuator for X-rays was investigated by experimental results which take into account mortar manufacturers barium through the different strains and compared with the reference material (Pb). The simulation results indicated that the ceramic block barium shows excellent properties of attenuation equivalence lead taking into account the energy used in diagnostic X-ray
