Atividade eletroencefalográfica de pacientes com acidente vascular cerebral na aprendizagem motora de um jogo baseado em realidade virtual

Stroke is the leading cause of long-term disability among adults and motor relearning is essential in motor sequelae recovery. Therefore, various techniques have been proposed to achieve this end, among them Virtual Reality. The aim of the study was to evaluate electroencephalographic activity of stroke patients in motor learning of a virtual reality-based game. The study included 10 patients with chronic stroke, right-hande; 5 with left brain injury (LP), mean age 48.8 years (± 4.76) and 5 with injury to the right (RP), mean age 52 years (± 10.93). Participants were evaluated for electroencephalographic (EEG) activity and performance while performing 15 repetitions of darts game in XBOX Kinect and also through the NIHSS, MMSE, Fugl-Meyer and the modified Ashworth scale. Patients underwent a trainning with 45 repetitions of virtual darts game, 12 sessions in four weeks. After training, patients underwent reassessment of EEG activity and performance in virtual game of darts (retention). Data were analyzed using ANOVA for repeated measures. According to the results, there were differences between the groups (PD and PE) in frequencies Low Alpha (p = 0.0001), High Alpha (p = 0.0001) and Beta (p = 0.0001). There was an increase in alpha activation powers and a decrease in beta in the phase retention of RP group. In LP group was observed increased alpha activation potency, but without decrease in beta activation. Considering the asymmetry score, RP group increased brain activation in the left hemisphere with the practice in the frontal areas, however, LP group had increased activation of the right hemisphere in fronto-central areas, temporal and parietal. As for performance, it was observed a decrease in absolute error in the game for RP group between assessment and retention (p = 0.015), but this difference was not observed for LP group (p = 0.135). It follows then that the right brain injury patients benefited more from darts game training in the virtual environment with respect to the motor learning process, reducing neural effort in ipsilesionais areas and errors with the practice of the task. In contrast, patients with lesions in left hemisphere decrease neural effort in contralesionais areas important for motor learning and showed no performance improvements with practice of 12 sessions of virtual dart game. Thus, the RV can be used in rehabilitation of stroke patients upper limb, but the laterality of the injury should be considered in programming the motor learning protocol.

Análise do comportamento de técnicas de correspondência binocular para imagens em alta definição

This work presents an analysis of the behavior of some algorithms usually available in stereo correspondence literature, with full HD images (1920x1080 pixels) to establish, within the precision dilemma versus runtime applications which these methods can be better used. The images are obtained by a system composed of a stereo camera coupled to a computer via a capture board. The OpenCV library is used for computer vision operations and processing images involved. The algorithms discussed are an overall method of search for matching blocks with the Sum of the Absolute Value of the difference (Sum of Absolute Differences - SAD), a global technique based on cutting energy graph cuts, and a so-called matching technique semi -global. The criteria for analysis are processing time, the consumption of heap memory and the mean absolute error of disparity maps generated.

Aprendizagem significativa: uma proposta de ensino e aprendizagem da geometria euclidiana espacial no ensino médio

This dissertation is a research based on the Meaningful Learning Theory, with students from the second year of High School, in the city named Capinzal do Norte, state of Maranhão. The pedagogic approach of this research focuses on what to do and how to do so students can better grasp knowledge inherent to the Euclidean Special Geometry in a more meaningful and changing way, also that information may be kept longer in their brain, so it can last longer in the present and future. The methodological strategy adopted was the research-action, followed by the constant observance of a researcher on the matter with the purpose to ensure consistent results, which come from the use of a variety of data collector instruments, such as: Concept Maps, manipulatives, educational softwares and application of evaluative tests, besides the observations made throughout the process of investigation and the diagnosis itself. It is all due to the fact that we rely on the premise that knowledge is assimilated in particular and idiosyncratic ways, which means each and every student learns in different ways and in different periods of time. That is why it is so important to develop diversified methodologies to the same subject. This research adds to the other ones related to the theoretical frameworks of the Meaningful Learning Theory, of Concept Maps, of the use of technology on the educational process and of manipulatives, which purpose is to connect their common dots. This pedagogical intervention also focuses on the construction of the educational orientations with applicability directly on class, directed specially by the Mathematics teacher of the basic education, who might use them during your teaching practice. Such guidelines established here as an educational product aim to follow the Theory's assumptions that serves as basis to this research, thus becoming an educational element with a relevant significance. The results, with which we are faced, proved overwhelming to the proposed objectives in terms of learning, which were evident in the construction of Conceptual Maps, as well as in the use of Concrete Materials, in addition to serving as a motivational element to participating students of research. The results obtained are indeed reliable in terms of learning, considered the expected goals, and made us certain that the way we have approached the subject is consistent with a holistic education and that at the same time values the tiniest details, which are fundamental to all the learning-teaching process.

Acurácia dos indicadores clínicos do diagnóstico de enfermagem falta de adesão em pessoas vivendo com AIDS

In the early 1990s, a major milestone in the treatment of Acquired Immune Deficiency Syndrome was the development of highly active combination antiretroviral therapy. The great benefit generated by the use of this therapy was prolonging the survival of the people who got this disease, since it is no longer considered fatal, becoming a chronic condition. Despite improvements generated by this therapy, there are still many difficulties to be overcome. One is the patient adherence to their treatment, bringing challenges to services and health professionals. Hence the need for early identification of nursing diagnosis Lack of Accession so that solutions are sought by the nurse with the patient and his family. With this problem, adds to the difficulty of hospital nurses in inferring that diagnosis, especially in identifying their defining characteristics. In this context, the objective was to evaluate the accuracy of clinical indicators of nursing diagnosis Lack of Adherence to antiretroviral treatment for people living with the Acquired Immunodeficiency Syndrome. The research took place in two stages. The first consists of the evaluation of the diagnostic indicators in the study; and second, the diagnostic inference performed by specialist nurses. The first step took place in a referral hospital in the treatment of infectious diseases in the Northeast of Brazil, and data were collected through an instrument for carrying out history and physical examination and analyzed for the presence or absence of the diagnostic indicators. In the second stage, the data were sent to experts, who judged the presence or absence of the diagnosis in the studied clientele. The project was submitted to the Ethics Committee of the Federal University of Rio Grande do Norte, obtaining approval with the General Certificate for Ethics Assessment (CAAE) No 46206215.3.0000.5537. Data were analyzed using descriptive and inferential statistics. Test were used Fisher's exact, chi-square test of Pearson and logistic regression. Since the accuracy of clinical indicators was measured by sensitivity, specificity, predictive values, likelihood ratios. As a result, we identified the presence of diagnosis Lack of Accession on 69% (n = 78) of the study patients. The defining characteristics that showed statistically significant association with the diagnosis studied were: lack of adherence behavior, complications related to development, missing scheduled appointments, failure to achieve results, and exacerbation of symptoms. The characteristic with greater sensitivity was missing scheduled appointments and the highest specificity behavior of noncompliance. The logistic regression showed as predictors for the diagnosis Lack of Accession: lack of adherence behavior, missing scheduled appointments, failure to achieve results, and exacerbation of symptoms. It was concluded that the identification of clinical indicators accurately enabled a good prediction of the nursing diagnosis Lack of Accession on people living with the Acquired Immune Deficiency Syndrome, helping nurses develop early on strategies for promoting adherence to the use of antiretrovirals.

Turismo e patrimônio cultural: processo de tombamento e estratégias de utilização turística do Centro Histórico de Natal/RN

In a globalized society, the relations between heritage and tourism are reflected in an ambiguous reality, shaped between the interests of preservation and the aspirations for economic benefits. On the one hand, the cities as a main generating cultural offerings needs to contemplate its heritage as a development axis, finding in the cultural tourism promotion a strategy to support the high cost of recovery and maintenance of its historical center and its expressions cultural. On the other, adds to the new requirements of demand, causing the tourism projects to turn to the cultural factor in the formation of their products, which allows municipalities to attract the growing cultural tourism segment. In this perspective, this study develops into a focused cross-cut in the analysis of Natal’s Historical City Center, in order to understand how this cultural heritage fallen has been used by the municipal administration for tourism. By understanding the heritage as a reference to identity and memory, as well as a cultural symbol of Natal society, characterized as an element surrounded by complex and strictly private situations, it identified the need for a qualitative approach to his deep understanding. The in-depth case study developed in two stages, first the realization of bibliographical and documentary research; and thereafter the interpretation of data collected through semi-structured interviews with municipal administrators and local residents. The survey results show that the official representatives of heritage are concerned about the preservation of the material dimension of the architectural heritage of the city, however, still can not reach and sensitize the local population, which seems to be part of a process that should be democratic and strengthening the sense of belonging of these people. Finally, it indicates an absence of revitalization strategies by the current municipal public administration for Natal’s Historical City Center, revealing a speech covered by a positivist interpretation of tourism, which deals with the use of assets by the scope of the marketing empiricism.

(Appendix B) Benthic foraminifera in Indian Ocean surface sediments

Multivariate analysis was performed on percentages of 46 species of unstained deep-sea benthic foraminifera from 131 core-top to near-core-top samples (322-5013 m) from across the Indian Ocean. Faunal data are combined with GEOSECS geochemical data to investigate any relationship between benthic foraminifera (assemblages and species) and deep-sea properties. In general, benthic foraminifera show a good correlation to surface productivity, organic carbon flux to the sea floor, deep-sea oxygenation and, to a lesser extent, to bottom temperature, without correlation with the water depths. The foraminiferal census data combined with geochemical data has enabled the division of the Indian Ocean into two faunal provinces. Province A occupies the northwestern Indian Ocean (Arabian Sea region) where surface primary production has a major maximum during the summer monsoon season and a secondary maximum during winter monsoon season that leads to high organic flux to the seafloor, making the deep-sea one of the most oxygen-deficient regions in the world ocean, with a pronounced oxygen minimum zone (OMZ). This province is dominated by benthic foraminifera characteristic of low oxygen and high organic food flux including Uvigerina peregrina, Robulus nicobarensis, Bolivinita pseudopunctata, Bolivinita sp., Bulimina aculeata, Bulimina alazanensis, Ehrenbergina carinata and Cassidulina carinata. Province B covers southern, southeastern and eastern parts of the Indian Ocean and is dominated by Nuttallides umbonifera, Epistominella exigua, Globocassidulina subglobosa, Uvigerina proboscidea, Cibicides wuellerstorfi, Cassidulina laevigata, Pullenia bulloides, Pullenia osloensis, Pyrgo murrhina, Oridorsalis umbonatus, Gyroidinoides (= Gyroidina) soldanii and Gyroidinoides cf. gemma suggesting well-oxygenated, cold deep water with low (oligotrophic) and pulsed food supply.

Sensibilizar para o desperdício alimentar: um projeto de educação para a cidadania

O desperdício alimentar constitui um problema à escala mundial. Em Portugal, no contexto de crise económica que vivemos importa combater a situação de desigualdade no acesso e no consumo de alimentos, o que implica sensibilizar a população para uma mudança de comportamentos. Neste sentido, para a promoção do combate ao desperdício alimentar e de uma cidadania mais ativa em matéria de sustentabilidade é fundamental recorrer a diversas estratégias, nomeadamente a nível educacional. Todavia, para que este processo de sensibilização produza os efeitos desejados é necessário chegar primeiro aos professores trabalhando com eles valores e saberes relativos à temática do desperdício alimentar. Neste contexto surge o projeto “Sensibilizar para o Desperdício Alimentar” desenvolvido pela Escola Superior de Educação de Santarém e que envolveu a conceção e implementação de uma ação de formação dirigida a professores do 1.º e do 2.º Ciclo do Ensino Básico. A apreciação que os professores fizeram da formação foi muito positiva, nomeadamente da pertinência das temáticas abordadas, da qualidade dos materiais e da metodologia adotada. A estas evidências soma-se o interesse demonstrado por outras instituições de ensino superior, que pretendem implementar, em breve, esta oficina de formação, o que nos incentiva a dar continuidade ao projeto.

Modelagem e análise dinâmica de um sistema de conversão de energia eólica dotado de gerador síncrono de imã permanente utilizando a plataforma ATP

Human development requires a broad balance between ecological, social and economic factors in order to ensure its own sustainability. In this sense, the search for new sources of energy generation, with low deployment and operation costs, which cause the least possible impact to the environment, has been the focus of attention of all society segments. To do so, the reduction in exploration of fossil fuels and the encouragement of using renewable energy resources for distributed generation have proved interesting alternatives to the expansion of the energy matrix of various countries in the world. In this sense, the wind energy has acquired an increasingly significant role, presenting increasing rates of power grid penetration and highlighting technological innovations such as the use of permanent magnet synchronous generators (PMSG). In Brazil, this fact has also been noted and, as a result, the impact of the inclusion of this source in the distribution and sub-transmission power grid has been a major concern of utilities and agents connected to Brazilian electrical sector. Thus, it is relevant the development of appropriate computational tools that allow detailed predictive studies about the dynamic behavior of wind farms, either operating with isolated load, either connected to the main grid, taking also into account the implementation of control strategies for active/reactive power generation and the keeping of adequate levels of voltage and frequency. This work fits in this context since it comprises mathematical and computational developments of a complete wind energy conversion system (WECS) endowed with PMSG using time domain techniques of Alternative Transients Program (ATP), which prides itself a recognized reputation by scientific and academic communities as well as by electricity professionals in Brazil and elsewhere. The modeling procedures performed allowed the elaboration of blocks representing each of the elements of a real WECS, comprising the primary source (the wind), the wind turbine, the PMSG, the frequency converter, the step up transformer, the load composition and the power grid equivalent. Special attention is also given to the implementation of wind turbine control techniques, mainly the pitch control responsible for keeping the generator under the maximum power operation point, and the vector theory that aims at adjusting the active/reactive power flow between the wind turbine and the power grid. Several simulations are performed to investigate the dynamic behavior of the wind farm when subjected to different operating conditions and/or on the occurrence of wind intensity variations. The results have shown the effectiveness of both mathematical and computational modeling developed for the wind turbine and the associated controls.

Entre as tramas da indústria da moda: argumentos sobre o trabalho escravo contemporâneo na sociedade de consumo

Even after its abolition, the slave labor still exists in the world. In a new socio-historic context, the shackles and slave quarters have been left behind, nowadays the workers are tempted, subjected to degrading conditions and have their rights retrenched. The contemporary slave labor has been emerging as subject of research in the Organizational Studies since the early 2000s, calling attention to many gaps to be filled about the way organizations all around the world use this practice. Contemporary slave labor is found in many and various economic activities, since coal to textile industries or even stores. In this dissertation, we have incorporated the consumption dimension to the field of Organizational Studies, discussing the modern slavery, aiming to understand the consumers’ point of view about this topic, that is, we have researched the consumers’ interpretations concerning the slave labor in the fashion industry. Our objective is to analyze consumer’s argumentative construction in the decision of buying or not products made by industries from the fashion field that were denounced because of slave labor usage. We have adopted fashion industry as research focus because it obscures the reflection of the consumers that feel like in a new world while shopping, a world of beauty and fantasy, seeking their own satisfaction. Furthermore, the Brazilian fashion industry is one of the biggest of the world (ABIT, 2015), with a huge symbolic strength in the country. We have realized a qualitative research using semi-structured interviews with 35 consumers to identify their arguments according to the criteria defined by Liakopoulos (2002): data, propositions, guarantees, supports and refutations. The data are the statements used by the interviewees categorically, that is, those which are clear in the interviews. The propositions are what qualifies and justifies the used data. The guarantees are related to the nature of the data, they are what gives the sense to the data and are introduced implicitly in the interviewee speech. The supports are universal premises introduced in order to legitimate the arguments. The refutations, when present, counter the used arguments. As results, we’ve found consumers who developed arguments pro-consumption and anti-consumption and who have defended ideas about the responsibility of different actors for the existence of this practice and for the fight against it. From these two categories: (1) pro-consumption – consume despite the complaints and (2) anti-consumption – don’t consume, because of the accusations; we have identified the following argumentative lines: skepticism, faultfinding and moral engagement. By the end, we have presented the interviewees’ argumentative construction and the obtained results.

“O CRISTO AFOGADO: UMA NÃO-CRISTOLOGIA” RELIGIÃO, LITERATURA E PÓS-COLONIALISMO

O objetivo dessa tese é aprofundar, a partir do discurso pós-colonial, uma crise na perspectiva teológica da libertação. Esta promoveu, na década de 1970, uma reviravolta nos estudos teológicos no terceiro mundo. Para tanto, leremos um conto de Gabriel García Márquez chamado “El ahogado más hermosodel mundo” (1968) analizando e avaliando as estratégias políticas e culturais ali inscritas. Para levar a frente tal avaliação é preciso ampliar o escopo de uma visão que divide o mundo em secular/religioso, ou em ideias/práticas religiosas e não religiosas, para dar passo a uma visão unificada que compreende a mundanalidade, tanto do que é catalogado como ‘religioso’ quanto do que se pretende ‘não religioso’. A teologia/ciências da religião, como discurso científico sobre a economia das trocas que lidam com visões, compreensões e práticas de mundo marcadas pelo reconhecimento do mistério que lhes é inerente, possuem um papel fundamental na compreensão, explicitação, articulação e disponibilização de tais forças culturais. A percepção de existirem elementos no conto que se relacionam com os símbolos sobre Jesus/Cristo nos ofereceu um vetor de análise; entretanto, não nos deixamos limitar pelos grilhões disciplinares que essa simbologia implica. Ao mesmo tempo, esse vínculo, compreendido desde a relação imperial/colonial inerente aos discursos e imagens sobre Jesus-Cristo, embora sem centralizar a análise, não poderia ficar intocado. Partimos para a construção de uma estrutura teórica que explicitasse os valores, gestos, e horizontes mundanos do conto, cristológicos e não-cristológicos, contribuindo assim para uma desestabilização dos quadros tradicionais a partir dos quais se concebem a teologia e as ciências da religião, a obra de García Márquez como literatura, e a geografia imperial/colonial que postula o realismo ficcional de territórios como “América Latina”. Abrimos, assim, um espaço de significação que lê o conto como uma “não-cristologia”, deslocando o aprisionamento disciplinar e classificatório dos elementos envolvidos na análise. O discurso crítico de Edward Said, Homi Bhabha e GayatriSpivak soma-se à prática teórica de teólogas críticas feministas da Ásia, da África e da América Latina para formular o cenário político emancipatório que denominaremos teologia crítica secular.

Las potencias subregionales en el sistema internacional de posguerra fría: ¿nuevos actores en la política internacional?

En trabajos anteriores, hemos avanzado en la identificación y diferenciación de tres categorías de potencias: potencias mundiales, potencias medias y potencias regionales. Pero, más allá de las potencias mundiales y las potencias medias que se encuentran en el centro del sistema-mundial, y las potencias regionales que se ubican en la semiperiferia, ¿es posible hablar de potencias que se encuentren en la periferia? Como se trata de Estados periféricos, ¿pueden ser calificados como “potencias”? ¿En qué radicaría su relevancia y envergadura? Dichas “potencias” ¿pueden ser agrupadas en una nueva categoría? De ser así ¿qué características compartirían? El objetivo de este documento es proponer una nueva  categoría de potencias en el sistema internacional: las potencias subregionales.

A Sobrecarga do Cuidador Informal do Doente de Alzheimer

Atualmente, é fundamental refletirmos sobre o impacto da doença de Alzheimer, dado que se trata de uma patologia neurodegenerativa com grande repercussõesquer nas funções intelectuais dos doentes e que afeta o seu dia-a-dia,quer na dinâmica do seu núcleo familiar. Deste modo, a rede de suporte formal e informal é crucial no que diz respeito à prestação de cuidados. São os familiares que se responsabilizam por essa tarefa que face ao caráter ininterrupto pode causar desgaste da saúde física e psicológica do cuidador. A sobrecarga carateriza-se pela soma dos problemas psicológicos, físicos e emocionais, sociais e financeiros, todos eles inerentes à prestação informal de cuidados. Este trabalho que tem como objetivo principal a avaliação do benefício/impacto físico, emocional, social e da saúde mental de um programa de grupo de suporte em cuidadores informais de doentes portadores da doença de Alzheimer.É crucial acompanhar o progresso do grupo de suporte, a evolução dos cuidadores informais e a sua capacidade de se manterem satisfeitos neste gruponos dois papéis: cuidador e pessoa. Os métodos utilizados para recolher estes dados foram um questionário sociodemográfico, a SCL-90-R para avaliar a sintomatologia e o Questionário de Avaliação de Sobrecarga do Cuidador Informal. Os resultados sugerem que o programa grupo de suporte altera a vida dos cuidadores informais, uma vez que estes, após o frequentarem, sentem menor sobrecarga nos aspetos da vida pessoal. No entanto, apesar dos progressosna vida pessoal dos cuidadores,estes não se sentem satisfeitos com a tarefa de cuidar. A sobrecarga de trabalho e suas exigências tornam o cuidador mais insatisfeito com as tarefas que está a exercer, uma vez queestas são vistas de forma negativa pelo mesmo. Pretende-se que o cuidador se sinta satisfeito, na medida do possível,nos dois papéis: no seu papel de cuidador e familiar.Este último motiva-o para a responsabilização social e pessoal, uma vez que sendo uma obrigação, esta pode ser feita de forma conformada.

Imprensa brasileira no ocaso da belle époque

A Grande Guerra foi o acontecimento ápice de tensões acumuladas entre as potências da Europa ainda no começo da segunda década do século XX. O conflito deflagrado no verão de 1914 expandiu-se e envolveu nações de outros continentes, tornando-o mundial, com repercussões que extrapolaram os mais de quatro anos de batalhas oficiais – atualmente pode-se concluir que a Segunda Guerra Mundial nada mais foi do que a segunda parte de um conflito que não acabou de forma a contentar todos os países beligerantes. Entretanto, a Grande Guerra também demarcou o final de uma era conhecida como belle époque, um tempo que simbolicamente representava o apogeu cultural, econômico e social na Europa, inspirador do modelo civilizador em nações no novo mundo, inclusive no Brasil. Na Amazônia, sobretudo na capital do Estado do Pará, Belém, vivia-se ainda sob o imaginário da era da abundância provocada pela exportação da borracha nativa, cujo inicio ocorreu no final do século XIX e na primeira década do século passado. Nesse cenário, desenvolveu-se um jornalismo forte e muito sintonizado com as questões nacionais, regionais e de além-mar. Formado por intelectuais, políticos e escritores, o jornalismo paraense cobriu de forma sistemática os acontecimentos em torno da Grande Guerra, desde a morte do herdeiro do trono do Império Austro-húngaro, Francisco Ferdinando, até a paz ser selada. Com base neste panorâma, o objetivo desta investigação centra-se no esforço para compreender a natureza da cobertura jornalística dos jornais paraenses acerca da Primeira Guerra Mundial, tendo como objeto de análise três jornais diários que circulavam à época: Estado do Pará, Folha do Norte e A Tarde. Os dois primeiros eram jornais generalistas e de longo período de circulação. O terceiro foi um jornal vespertino, publicado entre setembro de 1915 e setembro de 1916, portanto, de caráter ocasional. Para alcançar esse objetivo, a metodologia usada compreende as análises quantitativa e qualitativa de conteúdo, conforme descrito por Sousa (2006). A primeira parte das análises centra-se em avaliar os dados relativos ao número de peças, de espaços dedicados ao tema da guerra, entre outros aspectos quantificáveis. Na segunda parte usou-se a análise qualitativa com base no estudo do diálogo establecido entre os aspectos da historiografia e os achados jornalísticos nos três jornais.
