Validation of global forest change detection databases Abstract The main aim of the thesis is to validate selected databases of changes in forest areas based on the analysis of satellite imagery time series in the Czech Republic. For this purpose we are using databases of M. C. Hansen and P. V. Potapov which are mapping the evolution of forest areas internationally. For the purposes of validation, we have proposed a methodology primarily based on historical ortophotographs from 2000-2012, the same time period which is documented in the validated databases. The results obtained were statistically processed, allowing to assess the accuracy of validated databases. At the end of the thesis, we are discussing the causes of identified inaccuracies and presented with recommendations for future improvements of detection of changes in forest areas. Keywords: validation, forest, land cover, change detection, Hansen, Potapov

In 2006, the Ministry of Health reported that worldwide, Brazil ranked 2nd in the number of cases of the disease, surpassed only by India. The North region is the geographical area in Brazil that presents the most cases. In the state of Rio Grande do Norte, the disease is considered to be eliminated because its prevalence has been identified as 1 per 10.000 inhabitants, criteria established by the State Elimination Letter of 2005. Training programs have been offered by the Coordination for the Control of Hansen?s Disease Program of Rio Grande do Norte, PCH-RN since 1997, with the support of the English governmental agency Leprosy Relief Association, LRA, with no evaluation having been conducted. The objective of this study was to evaluate the training programs in clinical diagnosis of Hansen?s disease and their contribution to the detection of the disease in the state of Rio Grande do Norte. The study was conducted in seven municipalities that are known as Regional Public Health Units (URSAPs): S?o Jos? de Mipibu URSAP I, Mossor? URSAP II, Jo?o C?mara URSAP III, Caic? URSAP IV, Santa Cruz URSAP V, Pau dos Ferros URSAP VI and Natal, capital city of the State, in the Metropolitan Region. Physicians and nurses of the Family Health Program PSF were interviewed as to their perceptions of the implementation of the training program in clinica diagnosis of Hansen?s Disease conducted by the PCH-RN. They evaluated their own practice and the training program. These professionals presented a positive evaluation of the program and gave suggestions for future courses. The results of this study suggest the need for permanent education. Data of the disease obtained from the official records of the Secretariat of Health and from the interviews indicate that health education is the means to control Hansen?s disease effectively / A hansen?ase ? considerada um grave problema de sa?de p?blica, pois de acordo com dados do Minist?rio da Sa?de no ano de 2006, o Brasil posicionou-se em 2? lugar no mundo, em n?mero de casos da doen?a. A Regi?o Norte figura como a que mais apresenta casos. No Rio Grande do Norte, a hansen?ase j? ? considerada eliminada, pois possui menos de 1 caso/10.000 habitantes, segundo dados da carta de elimina??o de 2005. No Estado, treinamentos de cl?nica em hansen?ase tem sido oferecidos pela Coordena??o do Programa de Controle da Hansen?ase do Rio Grande do Norte (PCH-RN) desde 1997, com o apoio da organiza??o n?o governamental brit?nica The Leprosy Relief Association (LRA), sem nenhuma avalia??o ter sido realizada. O objetivo deste estudo foi avaliar o impacto do treinamento de cl?nica em hansen?ase e sua contribui??o para a detec??o da doen?a no Estado do Rio Grande do Norte. Para avaliar os treinamentos, foi escolhida a an?lise da interven??o. O estudo foi desenvolvido em sete munic?pios, os quais s?o as sedes das regionais de sa?de, atualmente designadas como Unidades Regionais de Sa?de P?blica (URSAPs), que s?o: S?o Jos? de Mipibu URSAP I, Mossor? URSAP II, Jo?o C?mara URSAP III, Caic? URSAP IV, Santa Cruz URSAP V, Pau dos Ferros URSAP VI e em Natal, a capital do Estado, que se localiza na regi?o metropolitana. Foram realizadas entrevistas com m?dicos e enfermeiros do Programa de Sa?de da Fam?lia (PSF), questionando as percep??es desses profissionais sobre a implementa??o do treinamento de cl?nica em hansen?ase, viabilizado atrav?s do Programa de Controle da Hansen?ase do Estado do Rio Grande do Norte. Os profissionais avaliaram a pr?pria pr?tica e o treinamento. Apresentaram uma avalia??o positiva e ofereceram sugest?es para os pr?ximos treinamentos. De acordo com os resultados deste estudo, h? necessidade da educa??o permanente. Tanto os dados oficiais sobre a doen?a apresentados pela Secretaria de Sa?de do Estado, quanto as respostas obtidas nas entrevistas, indicam que o caminho para o controle da hansen?ase, ? o da educa??o em sa?de

The purpose of this study is to describe, analyse and compare the use of the concept creativity in 1996- and 2009 culture propositions. Various aspects of creativity have been investigated using the methods of idea analysis and conceptual history. The result is presented on the basis of three issues that concern: what linguistic space creativity is given as a word; who is considered creative and; what function creativity has in cultural policy. Creativity has clearly gone from being a descriptive word to standing as its own concept in noun form, but in the sense of artistic renewal, the term is very present in both propositions. Most people are considered as having creative potential, but young adults and professional artists are the most prominent groups in the material. Artistic renewal is increasingly motivated by market interests, although other softer values are represented.

Aim: The aim of the present study is to evaluate, by means of the patients history and Speech Therapy evaluation, the auditory (auditory thresholds), vocal (vocal characteristics and maximum phonation times), and oral-facial functions (chewing, breathing, swallowing and speech) manifestations in Hansen s Disease patients of a public health center of the city of São Paulo/SP. Methods: The subjects of this study were 20 Hansen s Disease patients, between 18 and 45 years of age. Specific protocols were filled out for each patient. These protocols targeted the subjects auditory, vocal, and oral-facial functions history. Then, these aspects were evaluated through specific Speech Therapy evaluation methods. The results were described numerically and by percentages. Results: Considering the subjects who took part in this study (55% female and 45% mal), 45% had paucibacillary (PB) and 55% multibacillary (MB) Hansen s disease, and all were receiving treatment (MDT/monotherapy). Five subjects complained of auditory changes, three of vocal changes and two of altered oral-facial functions. Discussion:Case description may aid the speech therapist and other members of the multidisciplinary team to better understand the Disease, and its possible speech therapeutic manifestations; as well as to create various hypothesis and to clinically evaluate and design adequate treatment for these patients. Conclusion: The speech therapeutic manifestations observed were few, and it was not possible to establish that the occurrences of the observed alterations were related to Hansen s Disease. This fact may be justified by the patients adequate usage of medication, as well as by the short time-span between diagnosis and the beginning of treatment, and to the age-span considered in this research (18 to 45 years) / Introdução: A Hanseníase, doença crônica infecto-contagiosa e de notificação compulsória, é causada pelo bacilo de Hansen (Mycobacterium leprae), e pode apresentar múltiplas lesões em qualquer local do corpo, com maior freqüência na face, orelhas, nariz e cavidade oral. Objetivo: O objetivo do presente estudo é avaliar, por meio de levantamento do histórico e avaliação fonoaudiológica, as manifestações referentes à audição (limiares auditivos), voz (características vocais e tempos de fonação) e funções orofaciais (mastigação, respiração, deglutição, fala) em doentes de Hanseníase de um centro de atendimento do município de São Paulo/SP. Método: Fizeram parte deste estudo, 20 sujeitos acometidos pela Hanseníase, na faixa etária compreendida entre 18 a 45 anos. Foram aplicados protocolos para levantamento de histórico audiológico, vocal e das funções orais, e em seguida foi realizada uma avaliação fonoaudiológica desses aspectos. Os resultados foram descritos em número e percentual. Resultados: Dos pacientes pesquisados (55% mulheres e 45% homens), 45% eram do tipo paucibacilares (PB) e 55% multibacilares (MB), todos em tratamento (PQT/monoterapia). Dentre as alterações, cinco dos participantes se queixaram de alteração auditiva, três de alteração vocal e dois de alterações orofaciais, todos constatados em avaliação fonoaudiológica. Discussão: A descrição dos casos pode auxiliar o fonoaudiólogo, e os demais integrantes de equipe multidisciplinar, a entender melhor a doença e as possíveis manifestações fonoaudiológicas e, na presença de possíveis doentes, levantar hipóteses e realizar avaliação e tratamento adequados. Conclusão: as manifestações de característica fonoaudiológica foram registradas em número reduzido e não foi possível estabelecer que a ocorrência destas esteja diretamente relacionada à Hanseníase. Tal fato pode ser justificado pelo uso adequado do medicamento, por parte dos participantes, assim como o curto espaço de tempo entre o diagnóstico e o início do tratamento e a faixa etária pesquisada (18 a 45 anos)

Foram realizados testes de cointegração de Johansen em 13 variáveis macroeconômicas. O banco de dados utilizado são séries trimestrais e os testes foram realizados sobre as séries combinadas dois a dois, três a três e quatro a quatro. Utilizando esse método, encontramos modelos que cointegravam entre si, para os países analisados. A partir desses modelos, foram feitas previsões fora da amostra a partir das últimas 60 observações. A qualidade das previsões foi avaliada por meio dos testes de Erro Quadrático Médio (EQM) e Modelo do Conjunto de Confiança de Hansen (MCS) utilizando um modelo de passeio aleatório do câmbio real como benchmark. Todos os testes mostram que, à medida que se aumenta o horizonte de projeção, o passeio aleatório perde poder preditivo e a maioria dos modelos são mais informativos sobre o futuro da taxa de câmbio real efetivo. / This paper seeks to identify which variables are the most relevant for predicting the real effective exchange rate and analyze the robustness of these forecasts. Johansen Cointegration tests were performed on 13 macroeconomic variables. The database quarterly series are used and tests were carried out on the combined sets two by two, three by three and four by four. Using this method, we find models that cointegrated each other, for the countries analyzed. From these models, predictions were made out of the sample from the last 60 observations. The quality of the forecasts was assessed by the mean square error tests (RMSE) and Model Hansen Confidence Set (MCS) used a random walk model the real exchange rate as a benchmark. All tests show that, as we expand the forecast horizon, the random walk lose predictive power and most models are more informative about the future of the real effective exchange rate in the long term.

Estas duas classes de modelos distinguem-se quanto aos pressupostos e à mensuração do risco. Enquanto o CAPM considera apenas os dois primeiros momentos da distribuição de retornos, as outras medidas levam em conta os momentos superiores. Através da distância Hansen-Jagannathan, que mede o erro de mensuração do Stochastic Discount Factor (SDF) gerado pelos modelos, observou-se grande distinção dos modelos nos dois mercados. Enquanto o CAPM performou melhor no Dow Jones, os modelos de downside risk apresentaram melhores resultados para o Ibovespa, sugerindo vantagem na utilização destes modelos em mercados com menor liquidez e maior assimetria. / This dissertation proposes empirically test the downside risk models, Sortino, Upside Pontential Ratio, Omega and Kappa, by comparing them with the traditional CAPM, derived from the mean and variance boundary, using the listed shares in the Ibovespa and Dow Jones (DJIA) for the construction of market portfolios for each of the models. These two classes of models are distinguished in terms of assumptions and risk measurement. While the CAPM considers only the first two moments of the returns distribution, the other measures take into account the higher moments of such distributions. The Hansen-Jagannathan distance, which measures the Stochastic Discount Factor (SDF) measurement error generated by the models, showed a great distinction of the models in the two markets. While the CAPM performed better in the Dow Jones, the downside risk models presented better results for the Ibovespa, suggesting an advantage in the use of such models in markets with lower liquidity and greater asymmetry.

In 20 humanen, osteoporotischen Unterschenkeln wurde versucht eine Lauge-Hansen Supination-Eversions-Verletzung Stadium II zu reproduzieren. In 15 der 18 auswertbaren Proben waren Außenknöchelfrakturen induzierbar. Die Voraussetzung für die erfolgreiche Frakturinduktion war eine Mindestknochen- und Spongiosadichte des Außenknöchels gemessen mit pQCT an Innen- und Außenknöchel. Ansonsten kam es nur zu ligamentären fibularen oder tibialen Avuslionen. Entscheidend, ob eine Außenknöchelfraktur auf Höhe der Syndesmose oder distal entstand, war eine effektive, lateral gerichtete talofibulare Kraft. Jeweils sechs der 15 Außenknöchelfrakturen wurden mit winkelstabilen und nicht winkelstabilen Konturenplatten versorgt und biomechanisch getestet. Mit p kleiner 0,05 konnte signifikant gezeigt werden, dass zum Versagen der winkelstabilen Konturenplatte ein höheres Drehmoment und ein größere Außenrotation nötig waren, als für die nicht winkelstabilen Konturenplatte. Neben der biomechanischen Überlegenheit der winkelstabilen Konturenplatte konnte gezeigt werden, dass ihr Versagen im Gegensatz zur nicht winkelstabilen Konturenplatte unabhängig ist von der Knochendichte des Außenknöchels. / A Lauge-Hansen supination-external rotation fracture (LH SER II) was succeful reproduced in 15 of 18 human cadaveric ankles. The observed fracture pattern was a result of more than a simple external rotation deforming force applied to the supinated foot. It also depend on the presence of al laterally directed talofibular force an a BMD of the ankle over 90,6 mg/ccm. Otherwise you receive only ligament damage. Six fibular fractures were stabilized wiht conventional plates. Other six fibular fractures were stabilized with locking plates and biomechanical tested. Torque to failure (Nm) and angle at failure (degrees) were significantly greater on the side with locked plate than on the side with conventional plate. Our findings clearly demonstrate that the locking plate has greater biomechanical fixation properties than the conventional plates. In contrast to the failure of conventional plating the failure of locked plating was independent of the ankle BMD.

The aim of this thesis is to investigate how the conditions for the Swedish community school of art is affected by how it is organized and by political discussions and decisions on a national as well as on a local level. Additionally, how this affects children’s accessibility to the school. A qualitative content analysis of political documents was implemented through a mixture of Dorte Skot-Hansen’s model and Per Mangset’s definitions of cultural political rationalities, with the aim to both distinguish different rationalities used for giving the community school of art legitimacy, as well as discern possible tensions between economical, administrative and creative cultural political rationalities. The results show that there are various opinions about whether or not there should be a national strategy for support of the community school of art. Furthermore, that municipals have differences and similarities between their community schools of art. In conclusion, these different opinions and local variations in conditions affect the school’s accessibility to children.
