Avaliação de sistema de tratamento de dejetos suínos instalado no estado de Santa Catarina

Os dejetos suínos contribuem de forma significativa em prol da degradação dos recursos naturais e para a diminuição da qualidade de vida na região sul do estado de Santa Catarina, Brasil. O excesso de dejetos gerados pelo grande número dos suínos por unidade de área dificulta a solução do problema. Este trabalho teve como objetivo avaliar o comportamento de um sistema de tratamento de dejetos suínos, em série e em escala real, composto de unidades anaeróbias, unidades aeróbias e pós-tratamento. Os parâmetros analisados foram: DBO, DQO, PT, P-PO₄, N-NH₃, NTK, pH, clorofila a, biomassa algal, coliformes totais e coliformes fecais (Escherichia coli). O sistema mostrou que após um ano de funcionamento as eficiências de remoção foram satisfatórias para matéria orgânica e nutrientes, alcançando valores de 97% para DBO, 95% para DQO, 88% para N-NH₃ e 74% para PT/P-PO₄, mesmo com as variações de vazão e de carga orgânica aplicada. Entretanto, a remoção de coliformes fecais nas unidades aeróbias foi baixa, reduzindo somente 0,86 unidades log na lagoa facultativa aerada e 0,80 unidades log na lagoa de maturação.

Stratigraphic study and analysis of the barchan dunefield of the Laguna coastal zone in Santa Catarina, Brazil

The association of several favorable factors has resulted in the development of a wide barchan dune field that stands out as a fundamental element in the coastal landscape of southern Santa Catarina state in Brazil. This original ecosystem is being destroyed and highly modified, due to urbanization. This work identifies and discusses its basic characteristics and analyzes the favorable factors for its preservation, in the foreseen of both a sustainable future and potential incomes from ecotourism. The knowledge of the geologic evolution allows to associate this transgressive Holocene dunes formation to more dissipative beach conditions. Spatial differences on morphodynamics are related to local and regional contrasts in the sediment budget, with an influence on gradients of wave attenuation in the inner shelf and consequently with influence in the level of coastal erosion. The link between relative sea level changes and coastal eolian sedimentation can be used to integrate coastal eolian systems to the sequence stratigraphy model. The main accumulation phase of eolian sediments would occur during the final transgressive and highstand systems tracts. Considering the global character of Quaternary relative sea level changes, the Laguna transgressive dune field should be correlated with similar eolian deposits developed along other parts of the Brazilian coast compatibles with the model of dunefield initiation during rising and highstand sea level phases.

Evaluación del impacto del programa Monumenta en los centros históricos del sur de Brasil : los casos de Pelotas, Porto Alegre (Rio Grande do Sul) y São Francisco do Sul (Santa Catarina)

Esta Tesis tiene como objetivo demostrar que los programas de preservación del patrimonio, durante su fase de implementación, deben someterse a un análisis multidisciplinar que haga un balance de su ejecución. Dicho análisis permitirá identificar resultados significativos, capaces de fundamentar la rectificación de las bases conceptuales de la política pública en cuestión. Este reajuste podrá darse, por lo tanto, durante su vigencia y, de forma más relevante, posteriormente, sus motivos y resultados permitirán elaborar nuevas estrategias que serán aplicadas en futuros programas de intervención. Por otro lado se indagó, además, si las ciudades participantes en un programa nacional de preservación del patrimonio, regidas por normas y metas comunes, podrían alcanzar resultados diferentes. Para atender a estos objetivos, la investigación se encuentra enfocada a la realidad brasileña, siendo seleccionado como objeto de estudio el Programa Monumenta. Este Programa formó parte de la política pública cultural del Ministerio de Cultura con una importante implicación del Banco Interamericano de Desarrollo. Implementado a partir de 1999, procuró promover un proceso de recuperación urbana sostenible y de preservación del patrimonio de 26 Sitios Históricos Urbanos o Conjuntos de Monumentos Urbanos protegidos por el Instituto del Patrimonio Histórico y Artístico Nacional (Iphan). El Programa contó con el apoyo de la Unesco y del Iphan, así como con la participación de las Administraciones Municipales y/o Estatales, sectores privados y la sociedad civil. Las hipótesis planteadas en esta Tesis Doctoral fueron: (a) el análisis de los resultados en la fase de implementación de un programa de preservación del patrimonio es imprescindible, porque permite extraer conclusiones preliminares y orientar sus reformas; (b) los objetivos a corto plazo establecidos por el Programa Monumenta fueron alcanzados de modo diferenciado en las distintas ciudades beneficiadas; (c) a pesar de las diferencias, el Programa Monumenta presentó resultados preliminares positivos y significativos en la preservación del patrimonio histórico urbano brasileño. Los procedimientos metodológicos se centraron en un análisis cuantitativo, cualitativo y comparativo de los resultados alcanzados por tres ciudades beneficiadas por el Programa Monumenta, seleccionadas según su tamaño poblacional: Pelotas, Porto Alegre (Estado de Rio Grande do Sul) y São Francisco do Sul (Estado de Santa Catarina). Estos procedimientos fueron aplicados en los siguientes indicadores: utilización de los equipamientos culturales, características de la población y de los domicilios, variación de las actividades económicas, financiación destinada al sector privado para la recuperación de inmuebles y el fomento de la seguridad urbana. La Tesis ha englobado discusiones y conceptos abordados en las disciplinas de la Sociología Urbana, Geografía Urbana, Historia, Economía y Estadística de modo que se atribuye al objeto de investigación una visión interdisciplinar que ayudará a la comprensión de la teoría y la práctica preservacionistas. El análisis de la varianza, la regresión lineal y el análisis factorial fueron las herramientas estadísticas aplicadas sobre los datos con el objetivo de constatar la significación de los resultados y la relación de correspondencia entre algunas variables. Esta Tesis contribuye a la elaboración de una metodología analítica que puede ser aplicada en el cálculo de la superficie ocupada por las actividades económicas, con base en el método estadístico del Diagrama de Caja y Bigotes, de John Wilder Tukey. Las conclusiones corroboran las hipótesis planteadas y pretenden contribuir al diseño de las nuevas políticas públicas de preservación de sitios históricos de carácter urbano, enfatizando, con ello, la necesidad de evaluaciones más profundas de los resultados durante su fase de implementación. ---------------------------------------------------------------------------------- RESUMO--------------------------------------------------------------------------- A presente Tese apresenta como objetivo principal demonstrar que os programas de preservação do patrimônio histórico, durante a sua fase de implementação, necessitam de uma análise multidisciplinar sobre a sua execução. Essa análise permite identificar resultados significativos, capazes de fundamentar a retificação das bases conceituais da política pública em questão. A correção poderá, portanto, ser realizada tanto durante a sua vigência como posteriormente, ao permitir a elaboração de novas estratégias a serem aplicadas nos futuros programas de intervenção. Por outro lado, indagou-se se cidades participantes de um mesmo programa nacional de preservação do patrimônio histórico, regidas por normas e metas comuns, poderiam alcançar resultados não similares. Para atender tais objetivos, a investigação enfoca a realidade brasileira, tendo sido selecionado o Programa Monumenta como objeto de estudo. Esse Programa fez parte de uma política pública cultural do Ministério da Cultura, que atuou em parceria com o Banco Interamericano de Desenvolvimento. Implantado em nível nacional, a partir de 1999, visava promover um processo de recuperação urbana sustentável, bem como a preservação do patrimônio de 26 Sítios Urbanos Históricos ou Conjuntos de Monumentos Urbanos, protegidos pelo Instituto do Patrimônio Histórico e Artístico Nacional (Iphan). O Programa contou com o apoio da Unesco e do Iphan, além da participação das Administrações Municipais e/ou Estaduais, setores privados e sociedade civil. As hipóteses estabelecidas nesta Tese Doutoral foram: (a) a análise dos resultados na fase de implementação de um programa de preservação do patrimônio é imprescindível, pois permite extrair conclusões preliminares e orientar as suas reformulações; (b) os objetivos em curto prazo, estabelecidos pelo Programa Monumenta, foram alcançados de modo diferente pelas cidades beneficiadas; (c) apesar das diferenças, o Programa Monumenta apresentou resultados preliminares positivos e significativos sobre a preservação do patrimônio histórico urbano brasileiro. Os procedimentos metodológicos se centraram em análises quantitativa, qualitativa e comparativa dos resultados alcançados em três cidades beneficiadas pelo Programa Monumenta, selecionadas de acordo com o tamanho populacional: Pelotas, Porto Alegre (Estado do Rio Grande do Sul) e São Francisco do Sul (Estado de Santa Catarina). Esses procedimentos foram aplicados nos seguintes indicadores: utilização dos equipamentos culturais, características da população e dos domicílios, atividades econômicas, financiamento destinado ao setor privado para a recuperação dos imóveis e, ainda, o fomento da segurança urbana. A Tese inclui discussões e conceitos abordados nas disciplinas de Sociologia Urbana, Geografia Urbana, História, Economia e Estatística, de modo a atribuir ao objeto de investigação uma visão interdisciplinar e uma compreensão entre a teoria e a prática preservacionista. A análise de variância, regressão linear e análise fatorial foram as técnicas estatísticas aplicadas sobre os dados, com o objetivo de constatar a significação dos resultados e a relação de correspondência entre algumas variáveis. Esta Tese contribui com a elaboração de uma metodologia aplicada no cálculo da superfície ocupada pelas atividades econômicas, utilizando como método estatístico o Diagrama de Caixa e Bigodes, de John Wilder Tukey. As conclusões corroboram com as hipóteses estabelecidas e pretendem contribuir para o desenho de novas políticas públicas de preservação de sítios históricos de caráter urbano, enfatizando a necessidade de avaliações mais profundas dos resultados durante a sua fase de implementação. ---------------------------------------------------------------------------------- ABSTRACT ---------------------------------------------------------------------------------- The main goal of this PhD. Thesis is to demonstrate that a multidisciplinary analysis is needed during the implementation phase of preservation of heritage programmes. Such analysis allows the identification of significant results, which in turn can serve as the foundation for the conceptual bases of the public policy at hand. Thus, any corrections can be made both during the programme and afterward, by introducing new strategies to be applied in future intervention programmes. On the other hand, this project also asks whether cities participating in the same national preservation of heritage programme with common rules and goals can achieve distinct results. In order to meet these objectives, the project chose Brazil as its focus and Monumenta Programme for its object of study. This Programme is part of the Ministry of Culture’s public cultural policy, and was developed with cooperation by the Inter-American Development Bank. Implemented at the national level in 1999, the Programme aimed at promoting a process of sustainable urban renewal and the preservation of 26 urban historic sites or urban monumental ensembles, protected by the National Historic and Artistic Heritage Institute (IPHAN). UNESCO and IPHAN supported the Programme, and participants included municipal and state offices, private businesses, and local residents. The hypotheses established in this Doctoral Thesis were: (a) the analysis of the results in the implementation phase of a cultural public policy is imperative, because it enables preliminary conclusions to be drawn and orientate reforms; (b) the short-term objectives set out in the Monumenta Programme were achieved differently in the benefitted cities; (c) despite the differences, the Monumenta Programme displayed significant positive preliminary results in the conservation of the urban historic heritage in Brazil. Methodology procedures centered around quantitative, qualitative, and comparative analyses of the results achieved in three benefiting cities, selected according to population size: Pelotas, Porto Alegre (Rio Grande do Sul State) and São Francisco do Sul (Santa Catarina State). These procedures were applied to the following indicators: the use of the cultural facilities, characteristics of the population and the residential housing, variation of the economic activities, financing destined for the recovery of real estate, and promoting urban safety. The Thesis includes discussions and concepts addressed in urban sociology, urban geography, history, economics, and statistics, in order to examine the object of study with an interdisciplinary eye and an understanding between preservation theory and practice. Variance analysis, linear regression, and factorial analysis were the statistical techniques applied to the data, with the goal of defining the significance of the results and the correspondence ratio between some of the variables. This Thesis attempted to elaborate an applied methodology for calculating the space occupied by economic activities, using John Wilder Tukey's statistical method of Box-and-Whisker Plot. The conclusions corroborated the hypotheses established and are meant to contribute to the design of new public policies of historical site preservation in urban settings, emphasizing the need for deeper evaluations of the results during the implementation phase.

Spatial distribution of specialized cardiac care units in the state of Santa Catarina

OBJECTIVE To analyze the methodology used for assessing the spatial distribution of specialized cardiac care units. METHODS A modeling and simulation method was adopted for the practical application of cardiac care service in the state of Santa Catarina, Southern Brazil, using the p-median model. As the state is divided into 21 health care regions, a methodology which suggests an arrangement of eight intermediate cardiac care units was analyzed, comparing the results obtained using data from 1996 and 2012. RESULTS Results obtained using data from 2012 indicated significant changes in the state, particularly in relation to the increased population density in the coastal regions. The current study provided a satisfactory response, indicated by the homogeneity of the results regarding the location of the intermediate cardiac care units and their respective regional administrations, thereby decreasing the average distance traveled by users to health care units, located in higher population density areas. The validity of the model was corroborated through the analysis of the allocation of the median vertices proposed in 1996 and 2012. CONCLUSIONS The current spatial distribution of specialized cardiac care units is more homogeneous and reflects the demographic changes that have occurred in the state over the last 17 years. The comparison between the two simulations and the current configuration showed the validity of the proposed model as an aid in decision making for system expansion.

SEROLOGIC SURVEY ON HANTAVIRUS IN BLOOD DONORS FROM THE STATE OF SANTA CATARINA, BRAZIL

Emergent diseases such as Hantavirus Cardio-pulmonary Syndrome (HCPS) are able to create a significant impact on human populations due to their seriousness and high fatality rate. Santa Catarina, located in the South of Brazil, is the leading state for HCPS with 267 reported cases from 1999 to 2011. We present here a serological survey on hantavirus in blood donors from different cities of the state of Santa Catarina, with an IgG-ELISA using a recombinant nucleocapsid protein from Araraquara hantavirus as an antigen. In total, 314 donors from blood banks participated in the study, geographically covering the whole state. Among these, 14 individuals (4.4%) had antibodies to hantavirus: four of 50 (8% positivity) from Blumenau, four of 52 (7.6%) from Joinville, three of 50 (6%) from Florianópolis, two of 50 (4%) from Chapecó and one of 35 (2.8%) from Joaçaba. It is possible that hantaviruses are circulating across almost the whole state, with important epidemiological implications. Considering that the seropositive blood donors are healthy individuals, it is possible that hantaviruses may be causing unrecognized infections, which are either asymptomatic or clinically nonspecific, in addition to HCPS. It is also possible that more than one hantavirus type could be circulating in this region, causing mostly benign infections.

Mosquitoes (22 species) (0.5%) and Runchomyia reversa (5%) biting humans in the morning in Florianópolis, State of Santa Catarina, were significantly more common below than above waist and all Wyeomyia incaudata were collected below the waist. Short trousers are not recommended, unless using repellents.

Phlebotomine sandflies in a focus of dermal leishmaniasis in the eastern region of the Brazilian State of Santa Catarina: preliminary results (Diptera: Psychodidae)

Due to the occurrence of cases of dermal leishmaniasis in the Municipality of Piçarras, in the East of the Brazilian State of Santa Catarina, collections of Phlebotomine sandflies by the use of CDC-like light traps were developed near the houses of the patients. Three species (Lutzomyia neivai, Lu. fischeri and Lu. ayrozai) were collected. Lu. neivai was predominant near the houses, and Lu. ayrozai was collected in a secondary forest in a nearby municipality (Navegantes). The novelty of this focus, the most southern one in the East of Brazil, underscores the need for more complete studies on the sandfly fauna.

Association of ants (Hymenoptera: Formicidae) with bacteria in hospitals in the State of Santa Catarina

The objective of this study was to identify ant occurrence in hospital environments in the State of Santa Catarina, along with associated bacteria. Ants were collected monthly from five inpatient clinics in two hospitals in the municipality of Chapecó, from August 2003 to June 2004. They were collected under aseptic conditions using swabs moistened with sterile distilled water and put into test tubes containing BHI for microbiological analysis. After 24 hours, cultures were made in both 5% sheep blood and MacConkey agar, which were incubated for 24 hours at 35/37°C. The Gram characterization, culture identification and biochemical characterization followed standardized rules for clinical microbiology. Seven species of ants were identified, of which the most frequent were Monomorium pharaonis (71.5%) and Solenopsis saevissima (57%), and nineteen species of bacteria was isolated from hospital "A".

HIV genotyping among female sex workers in the State of Santa Catarina

The objective of this study was to investigate the frequency of HIV infection among female sex workers in the port area of Imbituba (State of Santa Catarina), and to identify the viral subtype and its susceptibility to antiretroviral medications. Ninety women were interviewed between December 2003 and February 2004. Six (6.7%) were HIV-positive. Genotyping for HIV, performed on four samples, detected subtype C in three of them, which is predominant in Africa and Asia, and subtype B in one of them, which is prevalent in Brazil, USA and Europe. The results suggest that the Port of Imbituba may be one of the gateways for HIV-1 subtype C to enter Brazil, and for its dissemination to the rest of the country and the Mercosul area, along the highway BR-101. This points towards the need for preventive work to reduce the introduction and dissemination of HIV subtype C in Brazil.

Seroepidemiological study of human cysticercosis with blood samples collected on filter paper, in Lages, State of Santa Catarina, Brazil, 2004-2005

INTRODUCTION: Human serofrequency of antibodies against Taenia solium antigens was determined and risk factors for cysticercosis transmission were identified. METHODS: Individuals (n=878) from periurban and rural locations of Lages, SC, were interviewed to gather demographic, sanitary and health information. Interviews and blood sample collections by finger prick on Whatman filter paper were performed from August 2004 to May 2005. Observation determined that 850 samples were suitable for analysis and were tested by ELISA using vesicular fluid of Taenia crassiceps heterologous antigen. To ensure the reliability of the results, 77 samples of the dried blood were matched with sera. The reactive samples were submitted to a serum confirmatory immunoblot (IB) test using purified Taenia crassiceps glycoproteins. RESULTS: The ELISA results for the dried blood and serum samples were statistically consistent. ELISA was positive in 186 (21.9%) out of 850 individuals. A group of 213 individuals were asked to collect vein blood for IB (186 with positive result in ELISA and 27 with inappropriate whole blood samples) and 130 attended the request. The IB was positive in 29 (3.4%) out of 850 individuals. A significant correlation (p = 0.0364) was determined among individuals who tested positive in the IB assay who practiced both pig rearing and kitchen gardening. CONCLUSIONS: ELISA with dried blood eluted from filter paper was suitable for cysticercosis population surveys. In Lages, human infection was associated with pig rearing and kitchen gardening. The prevalence index was compatible with other Latin American endemic areas.

Anti-HBs levels among children and adolescents with complete immunization schedule against hepatitis B virus. A cross-sectional study in Blumenau, State of Santa Catarina, Brazil, 2007-2008

INTRODUCTION: Vaccination is the main tool for preventing hepatitis B virus (HBV) infection; however, following the completion of the vaccination series, the concentrations of anti-HBs can decline over the years and reach levels less than 10mIU/mL. The persistence of protection in these individuals is still unknown. The present study aimed to determine the anti-HBs antibody levels among children and adolescents who had received a complete vaccination course for hepatitis B. METHODS: Antibodies against HBV surface antigen (anti-HBs) were tested in 371 individuals aged 10 to 15 years-old. RESULTS: Volunteers who showed undetectable quantities of anti-HBs accounted for 10.2% of the population studied and 39.9% presented antibody titers of less than 10mIU/mL. Anti-HBs > 10mIU/mL were verified in 49.9%. CONCLUSIONS: These results corroborate other studies indicating levels of anti-HBs below 10mIU/mL in vaccinated individuals. Additional studies are required to assess whether this indicates susceptibility to HBV infection and the need and age for booster doses.

Hepatitis B marker seroprevalence and vaccination coverage in adolescents in the City of Itajaí, State of Santa Catarina, Southern Brazil, in 2008

INTRODUCTION: Hepatitis B infection constitutes an important cause of morbidity and mortality worldwide. In Brazil, however, the current epidemiological situation is not clear. Considering the importance of establishing this prevalence, the aim of this study was to determine the prevalence of HBV markers in voluntary adolescents, junior high (secondary school) students, in the City of Itajaí, State of Santa Catarina, Brazil. METHODS: A seroepidemiological, transverse study was conducted with 353 randomly chosen adolescents from elementary school in 2008. Blood samples were analyzed for HBsAg, anti-HBc and anti-HBs. All analyses were conducted by automated microparticle enzyme immunosorbent assay (Abbott®, AxSYM system, Deerfield, IL, USA), according to the manufacturer's instructions. RESULTS: The prevalence of HBsAg was 0.6% (CI 95% 0.1 - 2.0), that of anti-HBc was 1.1% (CI 95% 0.3 - 2.9) and that of detectable anti-HBs was 83.6% (CI 95% 79.3 - 87.3). Hepatitis B vaccination coverage was 97.5% (CI 95% 95.2 - 98.8). CONCLUSIONS: These results demonstrate the success of the vaccination program against hepatitis B in the region studied and indicate that prevention strategies must be maintained and, if possible, expanded to contribute to the establishment of positive prevalence rates in all age groups.
