Respiratory tract diseases are of the most common infectious diseases among both children and adult population all over the world. Viruses are the most frequent cause of respiratory diseases. In healthy immunocompetent individuals respiratory infection proceeds mostly without major complications. Immunocompromissed hosts, for example patients after transplatation, are more susceptible to infection and even common infection may be life threatening for them. Human polyomaviruses KI (KIPyV) and WU (WUPyV) and human bocavirus (HBoV) are most frequently detected in the respiratory tract of patients with acute respiratory tract infection primarily in children and in immunosuppressed patients. However, clear causative link between presence of these viruses and the respiratory disease has not been established. In this retrospective study were tested by quantitative real-time PCR 822 (745 from adults and 77 from children) respiratory samples from 380 immunocompromissed patients included 326 adults and 54 children. Viruses were also detected in the 84 peripheral blood samples. The most frequently detected virus was HBoV (6,32 % positive pacients), followed by KIPyV (5,79 % positive pacients) and WUPyV (0, 53 % positive patients). Only HBoV was detected in blood samples. The study confirmed the presence of KI...

Thesis objective: This thesis focuses on postural and respiratory functions in adult patients with cystic fibrosis. Furthermore, it studies observations of common features in body posture. Finally, this thesis tries to evaluate life quality of patients with cystic fibrosis despite the fact of small experimental sample group used. Methods: between the years 2013 and 2014, 10 adult patients with cystic fibrosis diagnosis who were hospitalized at the department of tuberculosis and respiratory diseases at Motol hospital were examined. All examined patients belonged to the age category 18 to 30 years old. Methods used in examining the patients included spirometry, spine dynamic test, posture assesment software and at the end of all examinations a standardized questionnaire was given to all patients to evaluate the life quality of patients with CF (questionnaire of cystic fibrosis). Results: a common manifestation was the barrel-shaped thorax that increases its size in the anteroposterior direction, which causes thoracic kyphosis, shoulder protraction, stiffness of the ribcage and hyperlordosis of the lumbar spine. Conclusion: Patients with cystic fibrosis are to be found in all ranges of pulmonary functions. The most common complaint is the cough that distinctly affects their life quality (sleep...

Abstract This was a modified integrated mixed methods study of teachers’ perceptions of factors that influence transfer of research-based teaching strategies into classroom practice. Participants were made up of 66 respondents to a researcher made survey, “Survey of Teacher Attitudes toward Change and Classroom Implementation of Research–Based Strategies”. Respondents were divided into two groups based on participation in Louisiana Systemic Initiatives Programs (LaSIP): LaSIP, N= 39 and Non-LaSIP, N= 27. Answers to five research questions were based on analysis of quantitative data from a survey, recorded on a five-point Likert scale and qualitative data from analyses of transcripts of three personal interviews, two focus group discussions and five short-answer questions on the survey. SPSS software version 9 and Atlas.ti version 7 were used in quantitative and qualitative analyses, respectively. Concurrent quantitative and qualitative strands of data were integrated throughout the study. Findings from quantitative data included the following: (1) Teacher perceptions of features of the LaSIP were predictive of reported frequency of use of research-based teaching strategies (RBTS); (2) Reported frequency of use of RBTS was not significantly different in LaSIP versus non-LaSIP teachers, except in reported use of alternative assessments. (3) Both LaSIP and non-LaSIP teachers indicated that implementation of RBTS increased student achievement (4) LaSIP teachers identified factors such as opportunity to collaborate with colleagues, time to acquire content knowledge, practice with material and supplies as features of the LaSIP that influenced implementation of RBTS. (5) Perceived barriers to implementation of RBTS included lack of equipment and lack of teacher input into planning of professional development. and modeling of RBTS as factors that positively influence classroom implementation. Analyses of qualitative data supported many of the findings due to quantitative analyses. Additionally, qualitative data provided more in-depth information concerning teacher perceptions of barriers to implementation such as lack of teacher input into planning and implementation of professional development, and lack of time for in-depth learning during professional development activities. Key Words: Teacher Professional Development, Research-based Teaching Strategies, Classroom Implementation, Science Pedagogy, Mixed Methods, Student Achievement

By means of a Monte Carlo study, this paper investigates the relative performance of Listwise Deletion, the EM-algorithm and the default algorithm in the MICE-package for R (PMM) in estimating regression coefficients under a left truncated covariate with missing values. The intention is to investigate whether the three frequently used missing data techniques are robust against left truncation when missing values are MCAR or MAR. The results suggest that no technique is superior overall in all combinations of factors studied. The EM-algorithm is unaffected by left truncation under MCAR but negatively affected by strong left truncation under MAR. Compared to the default MICE-algorithm, the performance of EM is more stable across distributions and combinations of sample size and missing rate. The default MICE-algorithm is improved by left truncation but is sensitive to missingness pattern and missing rate. Compared to Listwise Deletion, the EM-algorithm is less robust against left truncation when missing values are MAR. However, the decline in performance of the EM-algorithm is not large enough for the algorithm to be completely outperformed by Listwise Deletion, especially not when the missing rate is moderate. Listwise Deletion might be robust against left truncation but is inefficient.

Tratando o tema Contabilidade de Custos, o objetivo desse trabalho consiste em verificar, dentre os propósitos de uso de métodos de custeio que compõem o referencial teórico de Contabilidade Gerencial e Contabilidade de Custos, quais se fazem presentes nas empresas objeto de estudo desta dissertação. Como objetivos específicos, buscou-se: (a) verificar entre os propósitos de uso do método de Custeio por Atividades propostos por Innes e Mitchell (1995), quais são adotados inclusive para os métodos de Custeio por Absorção e Custeio Variável; (b) identificar como os métodos de custeio são utilizados para atender os propósitos de uso; e (c) detectar por que determinados métodos de custeio são usados para determinados propósitos em detrimento aos demais métodos. Este estudo caracteriza-se como: (i) descritivo, (ii) correlacional e (iii) qualitativo; apoiado na metodologia de estudo de casos múltiplos. Como técnicas de coleta de dados, foram utilizados bibliografias e publicações, entrevistas com informantes-chave por meio de roteiros semi-estruturados e análise de documentos. A amostra pesquisada é constituída por cinco empresas privadas que atuam no Brasil nos segmentos Automobilístico, Ensino Universitário, Alimentos, Cartões de Benefícios e Agronegócios; selecionadas pelo critério não probabilístico e intencional por conveniência. Constatou-se que propósitos de usos apresentam relevância, porém não são únicos determinantes para a adoção de um ou outro método de custeio específico. Em todas as empresas objeto do estudo, os propósitos de uso de análise de lucratividade de produtos e orçamentos (elaboração) se fizeram presentes com métodos de custeio diferentes. Os métodos de custeio tradicionais (Absorção e Variável) foram identificados com uma quantidade maior de propósitos de uso do que o método de Custeio por Atividade. Os métodos de custeio não concorreram entre si, convivendo harmonicamente de maneira complementar. / Treating the topic Cost Accounting, the aim of this work is to verify, among the purposes of using costing methods that comprise the theoretical Managerial Accounting and Cost Accounting, which are present in the companies under study in this dissertation. Was sought, as specific objectives: (a) occur between the purposes of using the method Costing Activities proposed by Innes and Mitchell (1995), which are adopted including methods of Absorption Costing and Variable Costing, (b) identify how the costing methods are used to fulfill the purposes of use, and (c) detect that certain costing methods are used for certain purposes to the detriment of other methods. This study is characterized as: (i) descriptive, (ii) correlation and (iii) qualitative; supported the methodology of multiple case study. As techniques of data collection were used bibliographies and publications, interviews with key informants through scripts and semi-structured document analysis. The study sample consists of five private companies that operate in Brazil in the segments Automotive, College Education, Food, Cards and Benefits Agribusiness; selected by non-probabilistic and intentional for convenience. It was found that the purposes of uses are relevant, but are not sole determinants for the adoption of one or another specific costing method. In all the companies under study, the purpose of use of profitability analysis of products and budgets (preparation) were present with different costing methods. The traditional costing methods (Absorption and Variable) were identified with a larger quantity of purposes of use of the method Costing Activity. The costing methods do not compete with each other, living together harmoniously in a complementary way.

O refluxo gastro-esofágico é considerado fator responsável pela dificuldade alimentar na infância. A ocorrência de experiências negativas como vômitos, regurgitações, muitas vezes associadas a engasgos, esofagite, disfagia, odinofagia, pirose e dor retroesternal geram comportamentos de aversão ou recusa alimentar e desorganizam o processo de deglutição e alimentação. O presente estudo teve por objetivo avaliar a deglutição em crianças com diagnóstico clínico de refluxo gastroesofágico (RGE). Foram selecionadas 37 crianças, com diagnóstico clínico de refluxo gastro-esofágico e refluxo gastro-esofágico associado a queixas de dificuldades alimentares, com idades variando de 7 meses a 3 anos e 1 mês, idade média de 15,35 meses, sendo 25 (67,6%) do gênero masculino e 12 (32,4%) do gênero feminino. Participaram do grupo controle 15 crianças, saudáveis (estado geral e nutricional), que foram cuidadosamente triadas para assegurar adequado desenvolvimento neuropsicomotor e ausência de sintomas de refluxo gastro-esofágico e problemas respiratórios de repetição, na faixa etária de 6 meses a 3 anos e 2 meses, idade média de 20,5 meses; 9 (60,0%) do gênero feminino e 6 (40,0%) do gênero masculino. Para a avaliação funcional da deglutição foram utilizadas dietas de consistências líquida, pastosa e sólida em volume inicialmente de 5 ml e após em volume livre, habitualmente utilizado pela criança. Na avaliação videofluoroscópica, utilizou-se das dietas de consistências líquida e pastosa, em volume livre para o leite e 5 ml para a dieta pastosa, adicionadas ao contraste de bário. As crianças com refluxo gastro-esofágico apresentaram alterações na avaliação clínica com ingestão menos freqüente de consistência sólida, presença de náusea, recusa alimentar, engasgos e irritabilidade alimentar. Na avaliação objetiva para o alimento de consistência líquida houve penetração laríngea e movimento compensatório de cabeça em extensão, sendo este último também observado para o alimento de consistência pastosa. Entretanto, não houve diferença entre os tempos das fases da deglutição. O estudo permitiu concluir que crianças com RGE apresentam dificuldades relacionadas à aceitação alimentar, porém os tempos da dinâmica orofaríngea da deglutição não se alteram. / Gastroesophageal reflux is considered cause of infants feeding disorder. Negative experience such as vomiting, regurgitation; several times may be associated to choking, dysphagia and painfull swallowing produce aversion or feed refusal and causes a break up in the swallowing and feeding processes. This study evaluated the swallowing process in children with gastroesophageal reflux (GER), confirmed clinically and radiographically. We selected 37 children, with GER and GER complaints of feeding disorders, ages range from 7 months to 37 months, mean age of 15,4 months, consisted 25 males (67,6%) and 12 females (32,4%). The control group (GC) consisted of 15 healthy children (general and nourishing states), carefully chosen for not having any symptoms of GER, repetitive breathing disorders or developmental delays. The ages varied form 6 to 38 months, with mean age of 20,5 months, being 6 males (40%) and 9 females (60%). Swallowing evaluation (functional) considered three diets consistency: liquid, semi-solid and solid, beginning with 5 ml followed by free volume taken habitually by children. Free volume of milk and 5 ml of semi-solid, mixed with barium, were used during the videofluoroscopy. Children with GER presented alteration in clinical evaluations on 64,9% (n=24) and the control group on 13,3% (n=2), swallowing less diet solid diet, presents nausea, feeding refusal, choking and irritation. Videofluoroscopy evaluation for liquids, showed laryngeal penetration on 61,8 % (n =21) , GC 33,3% (n=5), and backward compensatory movement in 64,7% (n=22) e GC 0%, it was similar for the semi-solid diet 41,2% (n=14) e GC (n=0). There was no difference in time of the swallowing phases. This study shows that children with GER present difficulties to accepting feeding although no alteration on the oropharyngeal dynamics timing of swallowing was founded.

It aims at understanding the sense effects in these speeches. This dissertation considers the Discourse Analysis in the tradition of Michel Pêcheux that involves the relationship between discourse, the subject and ideology. For this purpose, on the one hand, the study brings theoretical elements related to Christianity, particularly to the Catholic Church and to the social political religious event &#8213;Círio de Nazaré&#8214; that happens annually in Belém, Pará, Brazil. On the other hand, the study develops fundamental notions such as: discursive formation, ideological formation, forgetting and silence among other elements that make it possible to build an analytic device in order to understand the discursive function of the RCS. This device is analyzed in Catholic women s speeches who claimed they were healed by the intercession of the Virgin of Nazareth. These experiences are called &#8213;miracles&#8214; by them. Considering the production condition of these speeches, the research aims at interpreting the sense effects of the linguistic materiality and their relationship with the discursive memory. The analysis demonstrates this relationship in utterances of the discursive corpus and it observes the interpellation established in the religious subjects when they produce speeches about miracles, updating the salvation promises to everyone who believe in the &#8213;Word of God&#8214; / Este estudo compreende reflexões sobre o Discurso Religioso Católico (DRC) sobre milagres com a finalidade de compreender os efeitos de sentido dele derivados. Foi construído a partir da base teórica da Análise do Discurso (AD), na tradição de Michel Pêcheux, envolvendo a relação entre discurso, sujeito e ideologia. Para isso, buscou, por um lado, subsídios de ordem teórica, relacionados ao Cristianismo, em particular à Igreja Católica e ao acontecimento sócio-político-religioso &#8213;Círio de Nazaré&#8214;, realizado anualmente na cidade de Belém do Pará; por outro, desenvolveu noções fundamentais, como formação discursiva, formação ideológica, esquecimento, entre outros, que possibilitaram a construção do dispositivo analítico com vistas à compreensão do funcionamento discursivo de DRC. Esse dispositivo foi utilizado na análise de discursos de mulheres católicas que, no interior do acontecimento, diziam-se curadas, por intercessão da Virgem de Nazaré, configurando, segundo elas, &#8213;milagres&#8214;. Considerando as condições de produção desses discursos, o objetivo do trabalho foi interpretar os efeitos de sentido a partir da observação da materialidade linguística em sua relação com a memória discursiva. Nas análises, buscou-se demonstrar essa relação nos enunciados constituintes do corpus discursivo, observando-se a forma de interpelação que se estabelece nos sujeitos religiosos ao produzirem discursos sobre milagres, atualizando a promessa de salvação a todos que tiverem fé na &#8213;Palavra de Deus&#8214;

Este estudo trata da trajetória profissional de Benedicta Valladares Ribeiro (1905-1989) na Escola Normal Modelo de Belo Horizonte, Minas Gerais, no período de 1926 a 1967. Teve a intenção de verificar se sua formação nos EUA influenciou o desempenho pedagógico da pesquisada, a qual dedicou grande parte de sua vida à educação. De forma pioneira, em 1926 foi em missão oficial do governo de Minas Gerais, com um grupo de professoras, estudar no Teachers College, na Universidade de Columbia nos Estados Unidos e, ao retornarem, trabalharam na reforma do ensino mineiro, auxiliando na implementação da Escola Nova. A fim de compreender sua atuação, em primeiro lugar foi abordado o governo mineiro de Antônio Carlos de Andrade, no qual Francisco Campos foi secretário do Interior o qual implementou a reforma da educação no Estado. Depois foram abordados outros aspectos relativos à face mulher e à esfera profissional de Benedicta V. Ribeiro. O último capítulo trata da sua trajetória profissional. Para consolidação da pesquisa foram utilizadas cartas pessoais de Benedicta trocadas com a família no período em que esteve nos Estados Unidos, as quais deram voz a essa jovem professora pesquisadora. Foram realizadas também entrevistas com ex-alunas, as quais elucidaram o seu percurso profissional. Destaque-se que a professora, ainda de forma pioneira, acreditava na importância da arte integrada a todo ensino e a necessidade de explorar com as crianças a imagem antes da escrita. O aperfeiçoamento no Teachers College influenciou significativamente a professora. Ela passou a ser uma admiradora de John Dewey e de outros educadores e filósofos precursores da Escola Nova. / This study deals with the career of Benedicta Valladares Ribeiro (1905-1989) in the Normal School Model of Belo Horizonte in Minas Gerais, in the period from 1926 to 1967. The study had the intention to determine whether the training in the U.S.A. has influenced the teaching performance of Benedicta, who devoted much of her life to education. In a pioneer way, in 1926 Benedicta went in an official mission of Minas Gerais government, with a group of teachers, in order to study at the Teachers College in the University of Columbia in the U.S.A. and when they returned, they worked in a reform of the education in Minas Gerais state, assisting in the implementation of the New School. In order to comprehend her performance, the government of Antônio Carlos de Andrade in Minas Gerais was the first approached, in which Francisco Campos, who was a country secretary, implemented the reform of education in the State. Then, it was discussed other issues related to women and to the Professional sphere of Benedicta V. Ribeiro. The last chapter deals with her professional career. To consolidate the research, Benedictas personal letters exchanged with her family in the period while she was in the United States were used, which gave voice to this young researcher professor. Also, interviews were conducted with her former students and that elucidated her Professional career. It is noteworthy that the teacher, even in a pioneer way, believed in the importance of art integrated into all education and the needs to explore with children the image before writing. The improvement at the Teachers College has significantly influenced the teacher, who became an admirer of John Dewey and other educators and philosophers precursors of the New School.

The main differences between this one and the industrial economy are: the information is the main input and output; the network effect is more usual and the price competition is not anymore so relevant. In this sense, this study presents three levels of analyze: first level, more abstract, shows the information s specificities; second level, shows theoretical questions about network economy and competition; and, at last, in a concrete level, shows the Google s competition strategy, trying to observe the explanation power of the theories discussed. / A questão central da presente dissertação é o estudo da economia digital, que se distingue da economia industrial principalmente pelas seguintes características: a informação é o principal insumo e produto; as empresas operam em redes e a competição via preços não é a estratégia concorrencial predominante. Nesse sentido, o trabalho apresenta três níveis de análise: inicialmente, em um nível mais abstrato, são abordadas as especificidades da informação; em um nível intermediário de abstração são apresentadas questões teóricas relativas às economias de rede e à concorrência; e, por fim, em um nível concreto, discute-se a estratégia concorrencial da empresa Google, buscando testar o poder explicativo das teorias apresentadas.
