Η εμφάνιση του Internet και των νέων τεχνολογιών έχει επιφέρει σημαντικές αλλαγές σε όλους τους τομείς του παραδοσιακού εκπαιδευτικού συστήματος. Η παρούσα διπλωματική εργασία πραγματεύεται τη μελέτη των διαφορετικών περιπτώσεων λογισμικών υποδομής, που έχουν υλοποιηθεί για εφαρμογές υποστήριξης της διαδικασίας μαθησιακής εξέτασης και αξιολόγησης στον Παγκόσμιο Ιστό. Υπάρχουν δύο κυρίως κατηγορίες λογισμικών υποδομής για εφαρμογές διαδικτυακής εξέτασης, οι οποίες είναι τα αυτόνομα πακέτα λογισμικού (stand-alone software) και τα Web-based λογισμικά. Σε ό,τι αφορά το κόστος, τα λογισμικά διακρίνονται σε λογισμικά ανοιχτού κώδικα (open source software) και σε εμπορικά διαθέσιμα λογισμικά (commercially distributed software). Στη συγκεκριμένη διπλωματική εργασία, ερευνώνται οι επικρατέστερες περιπτώσεις λογισμικού που είναι Web based και ελεύθερα διαθέσιμες. Μελετούνται διεξοδικά οι δυνατότητες και οι ελλείψεις κάθε περίπτωσης και γίνεται σύγκριση μεταξύ των διαφορετικών λογισμικών υποδομής. / Given the increasingly widespread growth of Open and Distance Learning Education, it is justifiable to discuss the main reasons that online examination systems exist and tend to grow rapidly. For this reason, we examine the way that Web-based Assessment and online examination software works and the quality of the services that offers. In this paper, we describe the similarities and the differences between three main online examination systems, TCExam, Pareeksha and PHPTestManager. The above mentioned comparison focuses on the tasks and activities that each system offers. We also investigate the reasons for the increasing abandonment of the traditional Pen-and-Paper Testing by Web-based Assessment systems.

The thesis is about assessment for learning. It aims to examine the gap between theory and practice in assessment for learning through a case study approach. By examining closely the assessment practice in one higher education institution in the UK, the thesis presents a number of original contributions to the literature, knowledge base and practice of assessment for learning. The thesis challenges the established literature in assessment for learning and proposes that the literature should move away from the dichotomised view of summative and formative assessment. The thesis also highlights the lack of an explicit theoretical underpinning in assessment for learning and proposes that the social constructivist approach should be made more explicit in the assessment for learning literature. With the case study demonstrating that lecturers often take a surface approach towards assessment for learning principles, the thesis proposes that dialogue needs to be seen as the common thread in assessment for learning. By understanding that assessment for learning is about a process that involves meaningful dialogue between 1) tutors and tutors, 2) tutors and learners, 3) learners and peers and finally 4) learners themselves, lecturers will be presented with a new knowledge base to re-consider their assessment practice. The case study also reveals that lecturers from certain disciplines found the notion of assessment for learning aligned with their disciplines more readily. This finding together with the contributions to literature and knowledge base will present a new perspective towards assessment for learning and look to inform practice that will result in a deep approach to assessment for learning.

Introdução: Os exames de Raios-X são utlizados para avaliação das curvaturas da coluna vertebral, porém, esses exames podem ser contra indicados em muitos casos, dessa forma a utilização da avaliação não invasiva é incentivada. Essa avaliação é baseada na palpação dos processos espinhosos que estão na superfície da pele, para isso, deve-se verificar se os resultados angulares oriundos dos processos espinhosos podem ser utilizados como forma de avaliação válida e reprodutível. Objetivos: (1) revisar na literatura os métodos invasivos de avaliação da coluna vertebral sagital; (2) desenvolver uma metodologia alternativa de medição das curvaturas sagitais da coluna vertebral, a partir dos processos espinhosos, baseada no cálculo da flecha sagital (f) e no ângulo (AF) das curvaturas originário da f; (3) verificar se essa metodologia é capaz de fornecer informações acuradas e precisas das curvaturas da coluna vertebral de crianças, a partir da avaliação da validade concorrente em relação ao padrão ouro, reprodutibilidade intra e interavaliador, sensibilidade e especificidade; e (4) identificar os limites de normalidade das curvaturas para a f e para o AF. Metodologia: Estudo 1 - A revisão sistemática da literatura foi realizada nas bases: Scopus, Science, Bireme e Pubmed. As palavras-chave utilizadas foram: "Validation Studies" OR “Reproducibility of Results” AND "Thoracic Vertebrae" OR "Lumbar Vertebrae" AND "Radiography”. Os principais desfechos extraídos foram os métodos utilizados para avaliar as curvaturas torácica e lombar da coluna vertebral no plano sagital através de exames de Raios-X. Estudo 2 - Para o estudo de validação, a amostra foi composta por exames de Raios-X da coluna vertebral de crianças, pertencentes a um banco de dados. Foram avaliadas, no plano sagital, as curvaturas torácica (n=90) e lombar (n=89). A análise estatística foi realizada no software SPSS versão 18.0, sendo o nível de significância de 0,05. Para a validade concorrente entre o AF e o AC foram utilizados: Teste de Correlação Produto-Momento de Pearson, Teste t independente, cálculo do erro RMS, Teste de Correlação de Morgan-Pitman e análise gráfica de Bland e Altman. Para a reprodutibilidade intra-avaliador das duas medidas do Av1 (1º dia x 2º dia) e para a reprodutibilidade interavaliador das medidas dos três avaliadores (Av1 x Av2 x Av3) foi utilizado o ICC, MAD, SEM e MDC. Resultados: Estudo 1 - Dos 1383 artigos previamente localizados, 22 artigos foram selecionados, em que, somente 2 apresentaram fraca evidência científica. Foram encontrados nove métodos diferentes. Com relação à reprodutibilidade dos métodos, os estudos mostraram resultados que variaram de moderada a excelente reprodutibilidade. Os artigos de validade mostraram grande correlação do método proposto com o padrão ouro; Estudo 2 - Tanto na região torácica (r= -0,763 com p<0,001), quanto na lombar (r= -0,686 com p<0,001), houve grande e significativa correlação entre o AF ajustado e o AC, o teste t de student não demonstrou diferença significativa entre os dois métodos, o baixo erro RMS determinou boa acurácia do método proposto, e a variância foi significativa na torácica, porém esse resultado não foi verificado na região lombar. A diferença média entre o AC e o AF ajustado (AC-AF) foi de 0°, tanto para a torácica e quanto para a lombar, e o desvio-padrão da média das diferenças na torácica foi de +12,4° e na lombar de +13,9°. AF ajustado e f apresentam boa especificidade e sensibilidade, porém alguns indivíduos foram classificados como falsos negativos na região torácica e alguns falsos positivos na região lombar. Os valores de ICC do AF ajustado foram semelhantes ou melhores do que os valores de ICC do padrão ouro, tanto intra quanto interavaliadores. Ainda, os valores de MAD, SEM e MDC do AF ajustado foram sempre menores do que os do AC,seja na coluna torácica ou na lombar. Os limites de normalidade na região torácica foram: de 0,97 cm à 3,83 cm para f e de 20° à 50° para o AF ajustado. Os limites de normalidade na região lombar foram: de 0,37cm à 3,81cm para a f e de 23,06° à 53,60° para o AF ajustado. Conclusão: O AF ajustado e f são válidos e reprodutíveis para avaliação da cifose torácica e da lordose lombar de crianças, apresentando fortes valores de correlação com o padrão ouro, bem como bons e excelentes valores de reprodutibilidade associados a baixos erros e variabilidade das medidas, indicando ser uma ferramenta precisa e confiável na avaliação da coluna vertebral. / Introduction: The X-ray examinations are utlizados to evaluate spinal curvatures, however, these tests may be contraindicated in many cases, so that the use of noninvasive evaluation is encouraged. This assessment is based on palpation of the spinous processes that are on the skin surface, for this we must verify that the angular results coming from the spinous processes can be used as an assessment tool valid and reproducible.Objectives: (1) review the literature about invasive methods for assessing sagittal spinal column; (2) developing an alternative method of measurement of the sagittal curvature of the spine, from the spinous processes, based on calculation of the sagittal fleche (f) and angle (AF) originating from the curvatures f; (3) verify that the methodology is able to provide accurate and precise information of the curvatures of the spine in children, based on the assessment of concurrent validity with respect to the gold standard, intra- and inter reliability, sensitivity and specificity; and (4) identify the boundaries of normality for f and AF. Methodology: Study 1 - A systematic literature review was performed on databases: Scopus, Science, Bireme and Pubmed. The key words used were: "Validation Studies" OR "Reproducibility of Results" AND "Thoracic Vertebrae" OR "Lumbar Vertebrae" AND "Radiography" The main outcome measures were extracted from the methods used to assess the thoracic and lumbar curvatures of the spine. in the sagittal plane by X-Rays Study 2 - For the validation study, the sample consisted of X-Ray of the spine of children belonging to a database. Toe thoracic curvature (n = 90) and lumbar (n = 89) Statistical analysis was performed using SPSS software version 18.0, and the 0.05 significance level to the concurrent validity between the AF and the AC were used.: Correlation Test Product-Moment Pearson, independent t test, RMS error of calculation, Morgan-Pitman's correlation test and graphical analysis of Bland and Altman. For intra-rater reproducibility of the two Av1 measures (Day 1 x 2nd day ) and for inter-rater reproducibility of the measurements of the three evaluators (Av1 x x Av2 AV3) was used intraclass correlation coefficient (ICC), and the MAD calculation, SEM and MDC. Results: Study 1 - Of the 1383 articles previously located, 22 articles were selected, in which only two showed weak scientific evidence. They found nine different methods. Regarding the reproducibility of the methods, the studies showed results which ranged from moderate to excellent reproducibility. The validity of articles showed high correlation of the proposed method with the gold standard; Study 2 - Both in the thoracic region (r = -0.763 p <0.001) and lumbar (r =-0.686 p <0.001), there was a great and significant correlation between AF and set the AC, the Student t test did not show significant difference between the two methods, low RMS error determined good accuracy of the proposed method, and the variance was significant in the chest, but this effect was not detected in the lumbari region. The average difference between the AC and the set AF (AF-AC) was 0°, both the thoracic and the lumbar for, and the average standard deviation of the differences in the thoracic was +12,4° and lumbar from +13,9°. AF set have good specificity and sensitivity, but some individuals were classified as false negatives in the thoracic region and some false positives in the lumbar region. The AF ICC values set were similar or better than the ICC values of the gold standard, both intra and inter-evaluators. Further, the MAD values, SEM and MDC set AF were always lower than AC, whether in the lumbar or thoracic spine. The normal range in the thoracic region were 0.97 cm to 3.83 cm for f 20° to 50° for the AF adjusted. The normal range in the lumbar were: 0,37cm to 3.81cm to f of 23,06° to 53,60° for AF set. Conclusion: AF adjusted and f are valid and reliable for evaluating clhilren´s thoracic kyphosis and lumbar lordosis, showing strong correlation values with the gold standard, as well as good and excellent reliability values associated with low errors and variability of the measures, indicating be a tool accurately and reliable the evaluation of the spine.

Conselho Nacional de Desenvolvimento Científico e Tecnológico / A dissertação analisa a política de formação docente oferecida pela Escola Normal de Niterói entre 1893 e 1915. O projeto de institucionalização da escolarização de professores representou momento de transformações significativas na profissão, então associada aos ideais de progresso e modernidade republicanos, com destaque para a circulação e apropriação de teorias pedagógicas. Buscou-se conhecer o lugar de tais teorias e dos saberes na formação institucional de professores, visando compreender, em que medida, as representações sobre a missão docente se fez presente nos discursos dos Presidentes de Estado no período. Com esse objetivo, analisamos as reformas de ensino e as frequentes inserções e retiradas de disciplinas escolares, em meio aos intensos debates na esfera governamental sobre o que ensinar ao povo e aos professores. Almejava-se um saber que fosse capaz de ampliar a visão do cidadão brasileiro, modificar seus hábitos e inseri-lo na modernidade, aspectos que condiziam com a construção de um espírito republicano. Para compreender o funcionamento e a contribuição dessa escola para a história da educação fluminense, analisamos a legislação educacional, os programas e as disciplinas, e também alguns exames de admissão e finais dos alunos. Foram utilizadas as mensagens dos presidentes do Estado (1892 a 1918), as leis que reformaram ou regulamentaram a instrução pública (1893, 1895, 1900, 1912 e 1915), em particular a Escola Normal de Niterói, os exames de admissão (1901 a 1908), os exames finais dos alunos (1897 a 1911) e um diário de Geografia (1915). Tais documentos foram analisados à luz de extensa historiografia sobre a formação docente e permitiram conhecer práticas escolares da instituição. As leis que modificaram os programas tentaram imprimir um caráter mais científico ao curso e muito se discutiu sobre a questão prática. Para tanto, as disciplinas tencionavam articular a teoria à experiência corroborando a aptidão do professor. A aprendizagem era verificada por meio de exames finais, que sucediam as sabatinas e as provas. Examinar era um dispositivo de poder que comparava e excluía e não apenas mensurava o conhecimento. Investigar a formação de professores nos levou a olhar as articulações históricas e as relações de forças que a constituíram. A pesquisa documental sugere a necessidade de ampliarmos a visão sobre a formação docente na Primeira República, tendo em vista que houve esforços em se organizar a instrução pública, sobretudo, no que concerne à Escola Normal de Niterói. / The research analyze the political aspect of teacher training by normal school at Niteroi city, between 1893 and 1915. The project of institutionalization and affirmation represented a time of significant in the profession. Therefore associate with republicans ideals and modernity, thus highlighting the movement and ownership of pedagogical theories. We attempted the place of educational theories and knowledge in the institutional teachers training. Understanding to what extent the representations about the teacher mission was present in the President of States speeches at the period. With that purpose we analyze educational reforms and the frequent insertion and withdrawals of school subjects. Under intense debate going on in the government, about what to teach to the people and teachers. Because the desire was acquaintance who was able to open mind of Brazilian citizens, change their habits and inserts it into modernity. Aspects that are consistent with the building of the Republican spirit. We analyze the education legislation, to understand how it worked and what contributed this school to the history of Fluminense education. Were also analyzed school programs and discipline, some admissions examinations e written test too. We used the president of the state messages (1894 to 1915), the laws of public education (1893, 1895, 1900, 1912 and 1915), especially the admission examination to the Normal Scholl at Niteroi city (1901-1908).The year-end exams of students (1897 to 1911) and a diary of geography (1915).These documents are reviewed under extensive historiography about the teacher training and allowed to know school practices of institution. The laws that changed the programs attempted to insert more scientific way and were questioned about the practical matter. Thus, the subjects had to articulate the theory and experience contributing the ability of the teacher. Learning is verified by final exams, which succeed the exams on Saturdays and regular tests Examine was a power device that compared and exclude, not just measure knowledge. Therefore investigate the teaches training show us the historical joints and power relationship that were part of it. The documental research shows a need to enlarge the overview about teachers training in the First Republic, have in mind that there were efforts to organize the public education, mainly regarding the Normal School of Niteroi city.

Orientador: Helio Langoni / Banca: Márcia Marinho / Banca: Antônio Carlos Paes / Resumo: A toxoplasmose é uma protozoonose causada pelo Toxoplasma gondii, de distribuição mundial e que acomete todos os animais homeotérmicos, incluindo o homem. Apresenta desde quadros assintomáticos a manifestações sistêmicas graves. Nos seres humanos a infecção atinge com maior gravidade principalmente indivíduos imunocomprometidos e gestantes, sendo que a primoinfecção, pode levar a óbitos, abortamentos, natimortos além de lesões severas do sistema nervoso central. Técnicas sorológicas precisas de fácil aplicação a campo e de menores custos, podem auxiliar na promoção de medidas de prevenção e controle, mas para isso é importante garantir a produção de antígenos em quantidade e de qualidade, a fim de atender as necessidades do método empregado, para garantir a sua padronização. A produção in vitro de taquizoítos de T.gondii usando células de sarcoma murino TG180 em histoculturas, mostra-se uma alternativa viável para a produção de antígeno de T. gondii, em quantidade e qualidade para uso no diagnóstico dessa infecção utilizando-se o Método de Aglutinação Direta, o que pode permitir sua difusão como um teste rápido a campo, possibilitando a sua utilização por profissionais autônomos ou unidades de saúde, podendo-se assim agilizar com uma maior rapidez as ações de prevenção dessa zoonose. / Abstract: Toxoplasmosis is one protozoonosis caused by Toxoplasma gondii, of world-wide distribution and that acomete to all the animals, including the man. It presents since without symptoms until serious clinical manifestations. In the human beings the infection reaches with bigger gravity immunocompromised patients individuals mainly and pregnant woman, being that the primary infecction, it can take the deaths, abortions, stillborn beyond severe injuries of the central nervous system. Serologicals techniques of easy application in the field and of lesser costs, can assist in the promotion of measures of prevention and control, but for this it is important to guarantee the production of antigens in amount and quality, in order to take care of the necessities of the employed method to guarantee its standardization. The production in vitro of taquizoitos of T.gondii using cells of sarcom murine TG180 in histoculture, reveals to a viable alternative for the antigen production of T. gondii, in amount and quality for use in the diagnosis of this infection by the Direct Agglutination Test, what it can allow its diffusion as a fast test in the field, allowing its use for independent professionals or units of health, and thus allowing to a bigger rapidity in the actions of prevention of this zoonose. / Mestre
