Terraços da margem leste da Laguna dos Patos, Litoral Médio do Rio Grande do Sul: estratigrafia e evolução holocênica

O presente trabalho discute os terraços lagunares da margem leste da Laguna dos Patos, localizados próximo à cidade de Mostardas. Através desse estudo é apresentado um novo modelo evolutivo para os últimos 5.000 anos no Litoral Médio do Rio Grande do Sul. Novas ferramentas foram utilizadas pela primeira vez no estudo da planície costeira do Rio Grande do Sul. Com respeito a aquisição dos dados de subsuperfície foi utilizado com êxito um GPR (Ground Penetretion Radar). Na análise e interpretação dos dados foi feita uma tentativa de aplicação da estratigrafia de seqüências. Através do uso de um scanner foram elaborados perfis dos testemunhos de sondagem, identificando aspectos distintos na composição e porosidade de diferentes litologias. Outras ferramentas utilizadas constam de sensoriamento remoto, nivelamento altimétrico e batimétrico, vibracore e datação radiométrica. Dessa forma, foram definidas três feições de terraceamento lagunar de idade holocênica na área de estudo, cada uma relacionada a um nível lagunar distinto. Através dos dados obtidos em subsuperfície foi possível traçar um esboço cronoestratigráfico, bem como uma curva de variação relativa do nível lagunar para a região. Também, como resultado dos dados geológicos de superfície, associados a novas interpretações baseadas em fotografias aéreas e imagens de satélite, foi elaborado um mapa geológico atualizado.

A implantação de uma universidade corporativa no setor público: o estudo de caso da escola de contas e gestão do tribunal de contas do Estado do Rio de Janeiro

The present research comprehends a case study, through which we analyzed the Programa de Implantação da Escola de Contas do Tribunal de Contas do Estado do Rio de Janeiro - Program of Implantation of the School of Public Finance of the Public Finance Court of the State of Rio de Janeiro - as a progressive educational strategy from the model of corporate university, considering the ten key components (steps) identified by Meister (1999) in his research. The qualitative approach has proved the most adequate for this study, as, regarding data interpretation and investigation process, the subjectivity of the researcher was taken into account, since he himself was designated to the Commission of Implantation of the School of Public Finance and is, presently, general Academic Coordinator of the Escola de Contas e Gestão (ECG) - School of Public Finance and Management, the main goal (product) of the mentioned program. As to the results, the study has shown that the Tribunal de Contas do Estado do Rio de Janeiro (TCE-RJ) has not equally emphasized the ten key components (steps) for the success in the construction of a corporate university, but none of them was neglected. Considering the way it presently works, it is also concluded that the ECG is relevant for the actuation of the TCE-RJ, but is not yet as connected to the performance as it should be. Fundamentally, the ECG still has to develop a personnel development system driven by personnel management through competences, performing a diagnosis of the essential organizational competences, mapping the existing ones, identifying the breaches and analyzing which of theses competences may be developed by means of their activities. Likewise, the ECG also needs to develop a methodology to assess the result as well as the impact of its activities. These circumstances, however, will be used to guide future studies and represent a new starting point.

Estudo da estrutura e funcionamento da educação especial nos sistemas estaduais de educação do Brasil

Este trabalho é um estudo sobre a organização do atendimento a excepcionais no Sistema Educacional Brasileiro, nas Secretarias de Educação e Cultura. Espera-se oferecer uma contribuição ao campo da Educação Especial, que se fundamenta em princípios filosóficos, hoje universais, de que todos têm igual direito à Educação. Na realidade educacional brasileira, constata-se que a execução desse direito não está ainda ao alcance de todos os excepcionais. A atual Estrutura e Funcionamento dos serviços de Educação Especial do País, entre outros fatores, não favorece ainda a universalização do atendimento, o estudo inicia-se por uma visão retrospectiva do que vem sendo feito no Brasil para sistematizar a educação dos excepcionais. Procurou-se também caracterizar a clientela e as estratégias de atendimento educacional adequadas. Com o objetivo de analisar a situação atual da organização da Educação Especial nas Secretarias de Educação do País, consideradas as características e necessidades dos educandos excepcionais, solicitaram-se aos Estados e Territórios informações sobre a Estrutura e Funcionamento dos órgãos responsáveis pela educação Especial. A interpretação dos dados, à luz do que técnica administrativa e filosoficamente se recomenda, conduz a algumas conclusões contidas neste trabalho.

Processo de planejamento estratégico em universidade pública: o caso da Universidade Federal do Pará

The goal of this research is to check if the strategic planning developed between 2001 and 2009 into the State University of Para (Universidade Federal do Pará - UFPA) was consolidated into its Academic Centers as a management practice. To this end, we identified the planning formalization degree of the Academic Centers, the conceived tools for the planning, the conception and the methodological process used in the tools elaboration, as also its implementation. The research used a qualitative approach: it is descriptive and it uses the case study technique. The data were gathered from primary and secondary sources, through bibliography, documents, and field researches through semi-structure interviews. The analysis and data interpretation were done by each investigated Academic Center from the analytics categories guided by the specifics goals. We used theoretic fundamental based principles and the university as a study empiric reference based on its structure analysis, organizational processes and institutional strategic plan. We inspected how the strategic planning process was developed throughout the fixed period and how the investigated Academic Centers are from the collected documents and interviews. The theoretical foundation was built from three axis: the Brazilian undergraduate and posgraduate education system; the university itself including its singularity and complexity as an organization; and the planning as a strategic management process. The main results show us that the UFPA has updated regulatory milestones, presenting organizational structure, laws, instructions, manuals and deployed management model that give the strategic planning development conditions beyond its administration, i. e., into its Academic Centers. The centers also present those established milestones and develop the basic planning processes of the institution. Those processes are conceived based on the institutional strategic planning and the managers mainly use the procedural orientation defined by the university management, from where the conceptual foundation is originated and propagated. According to the literature and to the research done in this work, we can conclude that the Academic Centers from the UFPA developed the strategic planning practice. This planning is organized and founded and guided the plans and decisions which avoided the disordered management and, according to the managers, allowed the advances and performance improvement. We can conclude that the UFPA built an important foundation with respect to the management professionalization. On the other hand, we can not conclude that the management practice is consolidated since there are weaknesses into the structuring of the technical teams and there is not any management tool for the implementation of the elaborated plans

A política de gestão de pessoas da UFPA: em sintonia com o gerencialismo?

This research examined the personnel policies of the Federal University of Pará (UFPA), aimed at the middle area, implemented by the President's Office of Personnel Management (PROGEP), through the Performance Management and Development from 2006 to 2009 period, in which Institutional Plan was implemented for Technical and administrative (PIDT) with a view to ascertaining whether these actions were developed in line with the ideas of managerialism or New Public Management (NPM). The study opted for qualitative research using interview as a tool to collect data. The informants were managers PROGEP / UFPA who acted in that period. Data interpretation was based on analysis of content from the collation of speeches and documents produced during the period with the managerial categories. Data analysis revealed that the management of people, UFPA has the characteristics of a hybrid management, observing the period studied two models of management: a bureaucratic, rational, focused on processes, contemporary face of public organizations, and other managerialist, adopted by PROGEP in obedience to the mandatory policies of the federal government, being much more present the characteristics of a personnel policy-oriented processes. Concludes that the personnel policy of the UFPA has not been fully tuned to managerialism in the surveyed period

Ciência e espiritualidade: conversas com pacientes terminais

It has been reflected on Science and spirituality having as focus the relation between them and the process lived by terminal patients after the confirmation of the finitude of their lives. It has searched with this research to excite discussions that corroborate the tematization of a possible dialogue between science and spirituality, signaling perspectives of debates and formation of an understanding of the problematic that involves these human constructs in the development of alternatives for the understanding of the life finitude. We point out the moment of split between science and spirituality through the cartesian paradigm from a historical approach and after focusing the illness and death as foundation for our discussion. We use as methodological strategy, focal talks with terminal patients having as guidance a guideline with five punctuations: the singular citizen, diagnosis impacts, indicators of science, spirituality marks and death fear that served of base for analysis and data interpretation in according to selected theoretical foundations. Thus, it was possible to perceive that science, although not to keep an explicit dialogue with spirituality, it has pointed through is representation forms to the process indicatives that will culminate with the death. And these indicators had shown that in this direction it is efficient. We believe that the confrontation of the death can happen through of a new science that dialogues with the spirituality, where does not have separation between reason and emotion on the part of science; as well as it does not have reason disdain on the part of the spirituality

Representações sociais de professor partilhadas por licenciados a partir de imagens de professor

This investigation had the teacher as object of study, whose objective was to know and analyze the teacher‟s Social Representations (SR) shared by undergraduates, as from images of this professional (teachers´ photos of several levels and school systems). It was searched out the process of depreciation or estimation, in which the teaching profession has been passing, trying to catch, specifically, possible existing correlations among such SR and the reflections in the attitudes developed by these students about their own development and professional practice. The data collection was carried out at the Federal University of Piauí Teresina with 165 undergraduates (15 from each course). It was applied a semi-structured interview, mediated by iconographic grouping (SALES, 2000, 2007), outlining a methodological widening of the studies fulfilled by (ROAZZI, 1995). It was used the function Factor Analysis, available in the SPSS (Statistical Package for the Social Sciences) for the analysis of the quantitative data, and it was proceeded a content analysis through the categorical analysis technique (BARDIN, 1977) for the analytical procedures of the qualitative data. It was resorted to the SR theory (MOSCOVICI, 1978) for the data interpretation and the Theory of Signs (PEIRCE. 1995) in the understanding of the decodification processes of signs that were present in the photos worked. It became evident that the undergraduates perceived the teaching profession inserted in a hierarchical scale of values (positive/negative), directly related to the school system and the teaching level, in which the teacher works. Most undergraduates share teacher‟s SR of negative content, consolidating the hegemonic SR about the teacher‟s social depreciation, although some of them imagine themselves, in the future, inserted among the teachers more appraised, showing that the SR orientate the positive and negative attitudes about the teacher. The presence of SR that mobilize the interviewers‟ attitudes in opposite senses related to the teacher, offer evidence of the necessity of future studies that can use a methodology more focused to understand other motivation factors that the undergraduates give evidence of having to the course they have chosen, besides the ones inferred by the SR caught in this investigation, as well as to establish a correlation between the teacher‟s SR (positive and negative) and the social economic level of the interviewers that share them. Such data revealed itself necessary since the literature signalizes for a relation between the course chosen and the applicant‟s social-economic level, and that the applicants‟ objective conditions to the licenciature courses are related to the subjective hopes that their group supplies

Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope

Avaliação operacional do controle mecânico de plantas aquáticas imersas no reservatório de Jupiá

O presente trabalho foi realizado com o objetivo de estudar a coleta e o descarte de plantas aquáticas em diferentes locais e infestações do sistema Tietê/Paraná, no reservatório de Jupiá. A operação foi realizada com auxílio de instrumentação instalada em uma colhedora de plantas aquáticas, com sistema de GPS dotado de sinal de correção diferencial. Os tempos gastos para carregar e descarregar a colhedora foram determinados por cronometragem, e a distância do ponto final de coleta ao ponto de descarte e o tempo de deslocamento, por cronometragem e uso de GPS convencional. em algumas coletas foram demarcados polígonos, instruindo-se o operador a trabalhar exclusivamente na área correspondente. A interpretação dos resultados permitiu determinar a participação do tempo de coleta em relação ao tempo total de operação, indicando um valor significativo do ponto de vista operacional (>70%). Considerando o descarte em áreas infestadas com taboa, o deslocamento total médio foi de apenas 383 m, com gasto médio de 200,96 s. Os valores de capacidade operacional da colhedora oscilaram entre 0,23 e 1,60 ha h-1, indicando valor médio de 4,48 ha dia-1. A maior limitação à capacidade operacional associou-se à velocidade média de deslocamento, com maior agravante em áreas com altas infestações ou profundas. Considerando-se o deslocamento da colhedora, houve grande dificuldade de orientação em condições normais de operação, inviabilizando a manutenção de espaçamentos uniformes entre as faixas de coleta e sobrepondo as passagens. Conclui-se que a avaliação operacional indicou a impossibilidade de operar a colhedora sem o auxílio de um sistema de navegação que permita orientar a sua movimentação nas áreas de controle.

Produção de sentidos sobre a maternidade: uma experiência no Programa Mãe Canguru

Este artigo analisa, sob a perspectiva da relação entre a família e instituições de saúde, os sentidos produzidos sobre a maternidade em um programa de saúde neonatal desenvolvido na rede pública - o Programa Mãe Canguru. A partir de entrevistas e observações feitas com usuárias durante sua participação no programa, buscamos apreender como as práticas discursivas e não discursivas sobre maternidade e maternagem, difundidas nesse processo, se articulam com as experiências concretas dessas mulheres para produzir novas configurações subjetivas. Na interpretação dos dados, realizada através de análise do discurso, os aspectos mais significativos das falas das entrevistadas foram agrupados em quatro núcleos de sentido: família e religião; o impacto do nascimento prematuro; desconfiança e resistência nas relações com instituições e profissionais de saúde; e a experiência com o Programa Mãe Canguru. Ao final, procurou-se identificar as principais estratégias e formas de singularização utilizadas por essas mulheres ao atribuírem sentidos ao papel materno.

Cytotoxic lignans from the stems of Styrax camporum (Styracaceae)

An ethanolic extract from the stems of Styrax camporum Pohl (Styracaceae), a plant traditionally used for gastrointestinal diseases, was fractionated and subjected to flash chromatography and afforded two benzofuran lignans, egonol and homoegonol, and one furofuran lignan, (+/-) syringaresinol, which were identified by spectral data interpretation. Their cytotoxic activities against Hep-2 (larynx epidermoid carcinoma), HeLa (human cervix carcinoma) and C6 (rat glioma) cell lines were evaluated using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) assay at several concentrations for 24 h. Activities could be observed for egonol against C6 (IC50 = 3.2 mu g/mL) and Hep-2 (IC50 = 3.6 mu g/mL) cell lines, and for homoegonol against C6 (IC50 = 4.9 mu g/mL) and HeLa (IC50 =- 5.3 mu g/mL) cells.

Influence of fluid volume variations on the calculated value of the left ventricular mass measured by echocardiogram in patients submitted to hemodialysis

The left ventricular mass (LVM) measurement is of major importance for renal patients, as ventricular hypertrophy is an important prognostic index. The echo-cardiogram of the ventricular mass is larger before than it is after hemodialysis, which can confuse data interpretation. The aim of this work is to study the influence of alterations in fluid volume on the variations in measurements of ventricular mass observed during the course of a hemodialysis. Sixteen patients with chronic renal insufficiency in hemodialysis were evaluated at the Dialysis Unit of the University Hospital-UNESP, Botucatu, São Paulo State. The left ventricular mass was calculated from echocardiograms taken before and after hemodialysis and simultaneous ultra-filtration (12 patients: UF GROUP) and before and after hemodialysis isovolemic phase with sequential ultra-filtration (10 patients: ISO GROUP). Six of these patients were submitted to measurements of left ventricular mass before and after hemodialysis in both isovolemic and simultaneous ultra-filtration procedures. In the UF group, there was significant reduction in the following parameters before and after dialysis: diastolic diameter from 54.0 +/- 6.0 mm to 45.6 +/- 7.6 mm; left ventricular mass from 342 +/- 114 g to 265 +/- 117 g; and its respective index (IMVE) from 214 +/- 68 g/m(2) to 168 +/- 71 g/m(2). The ISO group showed no statistically significant variation. The behavior of the variables of six patients submitted to both observations confirm these results. In conclusion, the variations in echocardiogram measurements of the left ventricular mass relating to hemodialysis appear to be induced by alterations of the volemic condition.

Estudo do potencial da técnica de nanossísmica para o monitoramento de hidrofraturamento em reservatórios de hidrocarbonetos

Hydraulic fracturing is an operation in which pressurised fluid is injected in the geological formation surrounding the producing well to create new permeable paths for hydrocarbons. The injection of such fluids in the reservoir induces seismic events. The measurement of this reservoir stimulation can be made by location these induced microseismic events. However, microseismic monitoring is an expensive operation because the acquisition and data interpretation system using in this monitoring rely on high signal-to-noise ratios (SNR). In general, the sensors are deployed in a monitoring well near the treated well and can make a microseismic monitoring quite an expensive operation. In this dissertation we propose the application of a new method for recording and location of microseismic events called nanoseismic monitoring (Joswig, 2006). In this new method, a continuous recording is performed and the interpreter can separate events from noise using sonograms. This new method also allows the location of seismic sources even when P and S phases onsets are not clear like in situations of 0 dB SNR. The clear technical advantage of this new method is also economically advantageous since the sensors can potentially be installed on the surface rather than in observation well. In this dissertation field tests with controlled sources were made. In the first test small explosives using fire works at 28 m (slant distances) were detected yealding magnitudes between -2.4 ≤ ML ≤ -1.6.. In a second test, we monitored perforation shots in a producing oil field. In this second test, one perforation shot was located with slant distances of 861 m and magnitude 2.4 ML. Data from the tests allow us to say that the method has potential to be used in the oil industry to monitor hydrofracture

Concepções dos agentes comunitários de saúde sobre suas práticas assistenciais

O presente estudo objetivou identificar as representações elaboradas por agentes comunitários de saúde (ACS) acerca de suas práticas assistenciais. Utilizamos a metodologia qualitativa de pesquisa, adotando, como instrumento de coleta de dados, a entrevista semiestruturada e, para a interpretação dos dados, recorremos à Análise Temática. Foram ouvidos 12 ACS das Equipes do Programa de Agentes Comunitários de Saúde (PACS) de um município do interior paulista. O material obtido permitiu verificar como temas: o vínculo como instrumento de trabalho e a prática pautada na promoção da saúde e na prevenção das doenças. Os relatos demonstram a importância do vínculo na prática diária, enfatizam os princípios humanitários que embasam as ações de solidariedade, destacam o sentimento de gratificação quando o trabalho executado é reconhecido pelas famílias e revelam que os sujeitos ouvidos têm dificuldades para discernir o alcance de seus limites. Embora estes profissionais apresentem um bom suporte técnico para o cumprimento de suas ações, também demonstram carência na instrumentalização para o exercício profissional. Concluímos que as diretrizes e normas estabelecidas para o PACS funcionam como norteadoras do processo de assistência, mas ainda não respondem a questões mais subjetivas encontradas na assistência ao indivíduo-famíliacomunidade. Além disso, os ACS parecem estar vulneráveis às flutuações de gestão dos municípios, estados e Governo Federal, apresentam inconsistência na ideologia do desempenho do próprio papel e não conseguem inverter o modelo assistencial pautado na doença e na intervenção médica individual.

Inquérito de saúde: comparação dos entrevistados segundo posse de linha telefônica residencial

OBJETIVO: Analisar diferenças quanto a características sociodemográficas e relacionadas à saúde entre indivíduos com e sem linha telefônica residencial. MÉTODOS: Foram analisados os dados do Inquérito de Saúde (ISA-Capital) 2003, um estudo transversal realizado em São Paulo, SP, no mesmo ano. Os moradores que possuíam linha telefônica residencial foram comparados com os que disseram não possuir linha telefônica, segundo as variáveis sociodemográficas, de estilo de vida, estado de saúde e utilização de serviços de saúde. Foram estimados os vícios associados à não-cobertura por parte da população sem telefone, verificando-se sua diminuição após a utilização de ajustes de pós-estratificação. RESULTADOS: Dos 1.878 entrevistados acima de 18 anos, 80,1% possuía linha telefônica residencial. Na comparação entre os grupos, as principais diferenças sociodemográficas entre indivíduos que não possuíam linha residencial foram: menor idade, maior proporção de indivíduos de raça/cor negra e parda, menor proporção de entrevistados casada, maior proporção de desempregados e com menor escolaridade. Os moradores sem linha telefônica residencial realizavam menos exames de saúde, fumavam e bebiam mais. Ainda, esse grupo consumiu menos medicamentos, auto-avaliou-se em piores condições de saúde e usou mais o Sistema Único de Saúde. Ao se excluir da análise a população sem telefone, as estimativas de consultas odontológicas, alcoolismo, consumo de medicamentos e utilização do SUS para realização de Papanicolaou foram as que tiveram maior vício. Após o ajuste de pós-estratificação, houve diminuição do vício das estimativas para as variáveis associadas à posse de linha telefônica residencial. CONCLUSÕES: A exclusão dos moradores sem linha telefônica é uma das principais limitações das pesquisas realizadas por esse meio. No entanto, a utilização de técnicas estatísticas de ajustes de pós-estratificação permite a diminuição dos vícios de não-cobertura.
