Esta dissertação parte da análise dos fluxos migratórios que vêm ocorrendo entre o município de Salvador do Sul, no Rio Grande do Sul, e os municípios do Oeste de Santa Catarina, mais especificamente Itapiranga, Palmitos, São Miguel d’Oeste, São Carlos e Tunápolis, no período de 1950 – 2000. O primeiro fluxo migratório ocorrente entre 1950 e 1970 teve como agente potencializador o “acesso a terra”. Jovens casais gaúchos emigraram rumo à fronteira agrícola do Oeste Catarinense, onde se ofereciam terras a preços baixos, constituindo pequenas propriedades familiares. No segundo fluxo, os filhos e netos desses primeiros migrantes que se estabeleceram no Oeste Catarinense migram de volta ao Rio Grande do Sul, na região dos municípios do Vale do Caí, entre os quais desponta Salvador do Sul. A motivação que leva a essa migração é a busca de emprego assalariado sem exigência de mão-deobra especializada, aliada à rede de parentesco existente no município.

Leptospirosis is a worldwide zoonosis of considerable medical and economical importance that affects humans in both urban and rural contexts, as well as domestic animals and wild fauna. Leptospira interrogans is the causative agent and is transmitted to humans by indirect contact with contaminated soil or water. The clinical syndromes include sub clinical infection, self-limited anicteric febrile illness, and severe and potentially fatal illness, known as Weil´s syndrome. In developed countries, leptospirosis is related to occupational or recreational activities while in developing countries, outbreaks occur during floods. In those regions, traditional strategies to prevent the transmission are difficulties to be implemented because of costs and lack of community acceptance. In addition, no efficient vaccine is available for human use. Several studies have suggested that chemoprophylaxis with doxycycline pre and post-exposure may be effective to prevent leptospirosis. Leptospirosis has been reported in rural areas of the State of Rio Grande do Norte, Brazil since 1985 in rice farmers who present the anicteric illness. The disease cause great social and economics impact. The study was conducted in São Miguel where an epidemic of leptospirosis in rice farmers was reported. The main objective was to determine the efficacy of doxycycline in preventing Leptospira exposure. A taxa de soroprevalência de leptospirose na população estudada antes e após a colheita foi de 14,2% (n=22) e de 16.6% (n=27) respectivamente. Anti-Leptospira serology was determined for 61 subjects in two instances, pre and post-exposure to potential contaminated water. There was an increased risk of 29.0 per cent in acquiring infection for individuals that did not use doxycycline. In addition, an increased risk of 30.0 % observed in farmers who did not use protection when exposed to Leptospira. The adhesion to preventive chemoprophylaxis was 55.7%. Therefore doxycycline, under specific circunstances appears to be an effective alternative to protect against leptosprirosis infection. A large sample composed of individuals to adhere to preventive therapy is needed to define time, dosage and length of use of doxycycline in this area

Este estudio investigó las actitudes y creencias de los estudiantes universitarios en Ciencias Químicas por la Universidad de Río Grande do Norte (UERN) como un paso hacia la elaboración de una propuesta de material didáctico para el estudio de las relaciones CTSA en la licenciatura en química. Para el conocimiento de las actitudes y creencias fue utilizado dos instrumentos (Escala Likert y un cuestionario), que proporcionó un análisis dentro del nuevo paradigma de investigación (cuantitativa y cualitativa) en la Enseñanza de la Ciencia y Matemáticas. Los resultados mostraron que los estudiantes de licenciatura en química tienen creencias positivistas y que suelen son considerados por algunos como ingenuas, como la creencia en el modelo de decisión tecnocrática, la linealidad del desarrollo científico y tecnológico que lleva a el bienestar social y neutralidad de los conocimientos científicotecnológico. Basándose en estos datos y la literatura sobre el tema se elaboraron tres módulos de aprendizaje: a) Cuestionando la hegemonía del conocimiento técnico y científico, b) Las relaciones entre ciencia, tecnología, sociedad y medio ambiente - las relaciones CTSA c) Propuesta de temática para la enseñanza de la química en una perspectiva de CTSA: El Río Mossoró. Por último, el material producido se utilizó en dos cursos ocurridos en el Campus Central en el Centro de Educación Superior en São Miguel, ambos de UERN. Los participantes expresaron su aprobación al enfoque trajo de el experimento propuesto y de el caso de simulación contenidos en la propuesta de

Having as reference the fundamentals of regional innovation systems (RIS) and the policy guidelines defined in the regionalization program implemented by the federal government, this study focus on the analysis of the so-called "Landmark Region", northern coast of Polo Costa das Dunas-RN, in order to indicate how the historical and cultural resources can support innovation in the tourism of the region, represented here by the cities of Pedra Grande and São Miguel do Gostoso. This is a descriptive research, using qualitative methods of data collection and analysis, configuring, still, as a case study. Data were gathered from literature, documents, semi-structured interviews and mainly by participant observation methods. The results show a great diversity of cultural resources in the region, both material and immaterial, which however are disarticulated, and need to be worked in order to be included in the tourism productive chain. The main opportunity for innovation regards the return of the Landmark to the region, an invaluable monument, with the construction of a memorial. Taking in account the relevance of the monument and the growth of the region, we conclude that the return of the Landmark to its place of origin, in conjunction with other cultural resources, could attract a flow of cultural tourists. This fact could be, as the theory suggests, characterized as market or niche innovation, as the region is dominated by the sun and sea and wind sports tourism

Hydrographic basins always exercised a big fascination over humankind that attracted for its scenery beauty or for its richness in natural resources, had been acting in order to modify these important ecosystems without, therefore, considering the possible consequences of these changes. The attributed importance to the coast ecosystems, in eminence to the hydrographic basin of Punaú river and adjacent areas, is had when it s verified the diversity of the ecosystems that contemplate it. Hydrographic basin in evidence in Rio Grande do Norte state, occupies an area of nearly 652.71 km², being it sited in the homogeneous micro-region Litoral Nordeste, with a regional population estimated in nearly 75,188 inhabitants, according to the Anuário Estatístico do Rio Grande do Norte 2004. The region of the researched basin is formed by seven municipal districts related as it follows: Maxaranguape, Pedra Grande, Pureza, Rio do Fogo, São Miguel de Touros, Taipu and Touros, but Maxaranguape, Rio do Fogo, Touros and Pureza have a direct participation in the basin. Basin in study have it lands evaluated according to the agriculturist aptitude by the conventionally methodology practiced in the country, having as objective, then, a compara-tive analysis between the ambient unities, Aeolian littoral and coast tray, identified in the researched area. From the characterization of the physic way of the area in study and owning the kept data, it was proceeded the integrated analysis of the structural elements of the landscape which were evidenced that the fragile areas are associated with the areas of agriculture cultivation, such as the ones of irregular occupation. About the degradation, the ambient diagnostic of the basin indicated that the equivalent to the Aeolian Littoral Ambient Unit correspond to the bigger pledging of the ambient quality, in other words, high ambient fragility, being this result due to the use and occupation of the soil, propitiating this way, vulnerability in the vegetal cover of the area, despite it disposes of a low agriculture cultivation percentage. Already in the Coast Ambient Tray, is emphasized the medium ambient fragility, despite of the high index of cultivated area. In a general way, the total area of the hydrographic basin of Punaú river and adjacent areas presented ambient impacts over the tolerance limit, indicating the necessity of a review of the practices of use and handling of the soil, reforesting of the water courses edges, control of erosion and contamination of the aqueous in the perspective to reduce the effects of the impacts due to the use and occupation of the basin in regard. The present search evaluated the ambient impacts diagnosised in the hydrographic basin of Punaú river and adjacent areas, pointing the causes and the probable consequences of the damages caused by these impacts to the basin ambient. From the analysis of these data, if was possible to become explicit how they are fundamental as key elements in the process of decision taking in the ambient questions

O sistema de cruzamento da espécie arbórea de dossel da Mata Atlântica brasileira, Cryptocarya moschata, foi estudado a partir de material proveniente do Parque Estadual Carlos Botelho, São Miguel Arcanjo, São Paulo, Brasil. As taxas de cruzamento foram determinadas através de marcadores alozímicos obtidos de plântulas germinadas de coortes de sementes coletadas de 35 árvores. O valor médio da taxa de cruzamento de equilíbrio (estimador indireto) foi t^eq = 0.51. As estimativas das taxas de cruzamento uniloco e multilocos (estimadores diretos) foram t^s = 0.725± 0,041 e t^m = 0,884 ± 0,034, respectivamente, indicando um sistema de cruzamento predominantemente alogâmico. As taxas de cruzamento de árvores individuais variaram de 27 a 100 ( x¯ = 87,8) porcento, a partir de t^m calculado com as freqüências gênicas de pólen mantidas constantes ao nível populacional. A partir do modelo de par de irmãos (modelo de cruzamento correlacionado) de Ritland, a correlação entre duas progênies irmãs oriundas de autofecundação (r^s) e a correlação entre duas progênies irmãs oriundas de paternidade por exocruzamento (r^p) foram 35,7% e 99,0%, respectivamente. Esses resultados corroboram o fato de haver variação nas taxas de autocruzamento entre as diferentes árvores, podendo também indicar que quando há endogamia, a maior parte das sementes nas árvores são provavelmente irmãs-germanas.

Nesta dissertação buscou-se refletir sobre as dificuldades de professores e alunos com relação ao ensino e à prendizagem de Física no ensino médio (EM). Construída à luz da Teoria Antropológica do Didático de Yves Chevallard, esta dissertação teve por objetivo apontar caminhos para a construção de nova(s) praxeologia(s) que considerem a (re)ligação/articulação dos vários conteúdos de Física, principalmente os do primeiro ano do EM, com a Matemática, evocando particularmente os conceitos de proporcionalidade e a regra de três algebrizada, para auxiliar na compreensão dos fenômenos físicos observáveis no dia-a-dia. Por meio de entrevista semi estruturada com 5 (cinco) professores que lecionam Física no ensino médio, em São Miguel do Guamá, estado do Pará, buscou-se entender, que tipo de relação estes estabeleciam entre a Física e os conceitos de proporcionalidade e destes com os fenômenos físicos. Por meio da análise das entrevistas constatou-se que a articulação entre a Física e a Matemática, com a intenção de compreender os fenômenos físicos, não era comum na prática de ensino dos professores de Física no ensino médio.
