Impacto da estratégia saúde da família com equipe de saúde bucal sobre indicadores de saúde bucal: análise em municípios do nordeste com mais de 100 mil habitantes

This study examined in municipalities of Northeast of Brazil with more than one hundred thousand people who incorporation of Oral Health Teams (OHT) into the Family Health Strategy (FHE) the possible impact on oral health indicators. Sought to answer whether implementation OHT brought the best indicators of health problems and coverage, compared to areas without coverage by the FHE through a community trial in parallel, quasi-randomized. In each of the municipalities surveyed were 20 census tracts, 10 were located in areas covered by oral health teams in the ESF and 10 industries in areas not covered. The final sample consisted of 59.221 individuals. We compared oral health indicators related to health problems, access to services and coverage of oral health actions. The analysis strategy was based on the calculation of prevalence ratios and confidence intervals, adjusted for confounding factors through Poisson regression with robust variance. It also has measured the association between an indicator of social inequality for comparison between areas. The best results are associated with indicators of access and coverage of oral health actions at the expense of the indicators of health problems, suggesting a possible maintenance of a traditional model of practice yet. The results also suggest a possible effect of a specific policy in the area of primary care on inequality in access. From the discussions presented throughout this work, we can see that the impact analysis of public policy, obtained by comparing areas with and without the intervention, not only captures the effect on the target population, but other dimensions of organization service and therefore should be understood as one of the analytical possibilities related to the management

Alfabetizar letrando: investigação-ação fundada nas necessidades de formação docente

The accomplished researches in the education field focus on the importance of the accomplishment of actions involved in the analysis of the needs to graduate teachers as a way to adequate to socialcultural changing that require more and more a creative activity to prepare teachers in their graduation perspective. The worry with a fail at school linked to public school students lead us to make this thesis which goals are: investigate the needs of the graduation of teachers at public Elementary Schools concerning to the subjacent knowledge to the development of a pedagogic practice of alphabetizing with literacy and (re)create, with some teachers as active participants in the researches, knowledge regarding the process of alphabetization with literacy , based on the graduation of teachers. The study was accomplished in a municipal Elementary School in the Ceará-Mirim city, located in the state of Rio Grande do Norte, which offers both I and II levels of the Elementary School, 7 teachers and the principal of the school were subjects of our researches. The starting point was the needs of the graduation as subject phenomena, socially created and that allow people to be aware of the goals of a graduation. The investigative broach is qualitative, whose fundamental purpose is the understanding of the meanings, symbols, values and intentions of the mankind actions, as regards to other humanbeing and the contexts in which they interact. Within this context, we chose the investigation-action for we consider this kind of research a place for investigation and professional graduation, in which teachers and the researcher herself assume responsibility of problematizing, build the needs of graduation and think about their practices. As proceedings to create and analyze data, we developed participant observations during the activities in classroom; semi-structured interviews (individual and in groups) with teachers and the principal; analysis of documents and meetings at school for reflexive studies that enabled us to gather data in a pyramidal panoramic view and analyze the contents. The research revealed that the analysis of necessities to graduate teachers is a resource able to contribute to the planning of projects of keeping on graduating more properly, and thus create a critical and reflexive identity for teachers. This way, it was possible the graduation necessities could be revealed and also the knowledge of teachers as regards to alphabetization inserted in a perspective of literacy. Nowadays, conceptualized needs upon difficulties of teachers, there is a tendency to translate them into theorization of problems, without application to these knowledge of teachers, as well as their wishes for changing, especially when those needs are built to analyze and consider concrete practices. Therefore, the graduation experiences have enabled the abandon of a mechanical broach for teaching reading and writing. It has also lead teachers to assume a posture of providing their students the understanding about the reading and writing processes and their functions as social instruments. The graduation theme contents allowed the knowledge to conceive reading and writing in new perspectives, according to their social functions, so that they can improve the education with literacy quality. This theoretical construction has enabled us to understand and consider the necessities of the graduation as progressive process, and has given us the possibility of re-think our own learning processes at the university and review the pedagogical practices of public school teachers. Our conclusion is that once teachers consider their own graduation needs, it contributes to change their concepts and practices in education and literacy, even though there used to be many difficulties in their graduation and organization of the pedagogical work

Análise da indução de fluxo de ar por convecção livre em chaminé solar

Experiments were performed to study the effect of surface properties of a vertical channel heated by a source of thermal radiation to induce air flow through convection. Two channels (solar chimney prototype) were built with glass plates, forming a structure of truncated pyramidal geometry. We considered two surface finishes: transparent and opaque. Each stack was mounted on a base of thermal energy absorber with a central opening for passage of air, and subjected to heating by a radiant source comprises a bank of incandescent bulbs and were performed field tests. Thermocouples were fixed on the bases and on the walls of chimneys and then connected to a data acquisition system in computer. The air flow within the chimney, the speed and temperature were measured using a hot wire anemometer. Five experiments were performed for each stack in which convective flows were recorded with values ranging from 17 m³ / h and 22 m³ / h and air flow velocities ranging from 0.38 m / s and 0.56 m / s for the laboratory tests and air velocities between 0.6 m/s and 1.1m/s and convective airflows between 650 m³/h and 1150 m³/h for the field tests. The test data were compared to those obtained by semi-empirical equations, which are valid for air flow induced into channels and simulated data from 1st Thermodynamics equation. It was found that the chimney with transparent walls induced more intense convective flows than the chimney with matte finish. Based on the results obtained can be proposed for the implementation of prototype to exhaust fumes, mists, gases, vapors, mists and dusts in industrial environments, to help promote ventilation and air renewal in built environments and for drying materials, fruits and seeds

Avaliação longitudinal do impacto da saúde bucal na estratégia saúde da família em Natal

As a result of the financial incentive provided by the GM / MS 1.444, since 2000, Brazil has experienced a substantial increase in the number of oral health services at the Family Health Strategy. There is, however, evidence that these teams have produced qualitatively different experiences which do not translate necessarily into improved quality of life and health. Thus, evaluative research of great importance. This study aims to assess the impact of the Family Health Strategy in oral health in a longitudinal perspective natalense the years 2006 and 2009. This is an intervention study whose design is a community trial in parallel, nearly randomized. The sample consisted of census tracts covered by oral health teams in the Family Health and the Traditional Model (Basic Health Units and non-FHS Program of Community Health Agents and areas not covered.) The sample was determined by drawing ten census tracts to form the experimental group and ten other sectors for the control group by pairing intentional based on socio-economic and geographic. To check the net effect of the intervention was performed multivariate analysis by Poisson regression. As a result of cross-sectional analysis of year 2009, it was found that the effects of the ESF in Natal were satisfactory only for the variables of injuries and for other purposes without and with negative impact on stock coverage reclaimers. However, the longitudinal analysis revealed that the ESB / ESF improved their performance in dealing with grievances, access and coverage of the type of actions and this fact is independent of age, sex and social and economic conditions. In other employees' words are related to the presence of the Family Health Strategy in the region. However it does not say that both models under study (the Family Health Strategy Model and Traditional) are different in terms of performance and it is pertinent to reflect on the need for further development of evaluation studies that use other approaches able to clarify the dynamics of the process whose results can come to the knowledge of the actors responsible for leading the ESF and encourage them to incorporate the assessment in their routine

Caracterização de subpopulações de interneurônios imunorreativos para proteínas ligantes de cálcio no córtex pré-frontal do Sagui (Callithrix jacchus): distribuição e morfologia

Cortical interneurons are characterized by their distinct morphological, physiological and biochemical properties, acting as modulators of the excitatory activity by pyramidal neurons, for example. Various studies have revealed differences in both distribution and density of this cell group throughout distinct cortical areas in several species. A particular class of interneuron closely related to cortical modulation is revealed by the immunohistochemistry for calcium binding proteins calbindin (CB), calretinina (CR) and parvalbumin (PV). Despite the growing amount of studies focusing on calcium binding proteins, the prefrontal cortex of primates remains relatively little explored, particularly in what concerns a better understanding of the organization of the inhibitory circuitry across its subdivisions. In the present study we characterized the morphology and distribution of neurons rich in calcium-binding proteins in the medial, orbital and dorsolateral areas of the prefrontal cortex of the marmoset (Callithrix jacchus). Using both morphometric and stereological techniques, we found that CR-reactive neurons (mainly double bouquet and bipolar cells) have a more complex dendritic arborization than CB-reactive (bitufted and basket cells) and PV-reactive neurons (chandelier cells). The neuronal densities of CR- and CB-reactive cells are higher in the supragranular layers (II/III) whilst PV-reactive neurons, conversely, are more concentrated in the infragranular layers (V/VI). CR-reactive neurons were the predominant group in the three regions evaluated, being most prevalent in dorsomedial region. Our findings point out to fundamental differences in the inhibitory circuitry of the different areas of the prefrontal cortex in marmoset

Análises estratigráfica e estrutural da Seção Rifte (Valanginiano ao Barremiano) na área do levantamento sísmico 3D de baixo vermelho, Bacia Potiguar emersa

Baixo Vermelho area, situated on the northern portion of Umbuzeiro Graben (onshore Potiguar Basin), represents a typical example of a rift basin, characterized, in subsurface, by the sedimentary rift sequence, correlated to Pendência Formation (Valanginian-Barremian), and by the Carnaubais fault system. In this context, two main goals, the stratigraphic and the structural analysis, had guided the research. For this purpose, it was used the 3D seismic volume and eight wells located in the study area and adjacencies. The stratigraphic analysis of the Valanginian-Barremian interval was carried through in two distinct phases, 1D and 2D, in which the basic concepts of the sequence stratigraphy had been adapted. In these phases, the individual analysis of each well and the correlation between them, allowed to recognize the main lithofacies, to interpret the effective depositional systems and to identify the genetic units and key-surfaces of chronostratigraphic character. The analyzed lithofacies are represented predominantly by conglomerates, sandstones, siltites and shales, with carbonate rocks and marls occurring subordinately. According to these lithofacies associations, it is possible to interpret the following depositional systems: alluvial fan, fluvio-deltaic and lacustrine depositional systems. The alluvial fan system is mainly composed by conglomerates deposits, which had developed, preferentially in the south portion of the area, being directly associated to Carnaubais fault system. The fluvial-deltaic system, in turn, was mainly developed in the northwest portion of the area, at the flexural edge, being characterized by coarse sandstones with shales and siltites intercalated. On the other hand, the lacustrine system, the most dominant one in the study area, is formed mainly by shales that could occur intercalated with thin layers of fine to very fine sandstones, interpreted as turbidite deposits. The recognized sequence stratigraphy units in the wells are represented by parasequence sets, systems tracts and depositional sequences. The parasequence sets, which are progradational or retrogradational, had been grouped and related to the systems tracts. The predominance of the progradation parasequence sets (general trend with coarsening-upward) characterizes the Regressive Systems Tract, while the occurrence, more frequently, of the retrogradation parasequence sets (general trend with finning-upward) represents the Transgressive System Tract. In the seismic stratigraphic analysis, the lithofacies described in the wells had been related to chaotic, progradational and parallel/subparallel seismic facies, which are associated, frequently, to the alluvial fans, fluvial-deltaic and lacustrine depositional systems, respectively. In this analysis, it was possible to recognize fifteen seismic horizons that correspond to sequence boundaries and to maximum flooding surfaces, which separates Transgressive to Regressive systems tracts. The recognition of transgressive-regressive cycles allowed to identify nine, possibly, 3a order deposicional sequences, related to the tectonic-sedimentary cycles. The structural analysis, in turn, was done at Baixo Vermelho seismic volume, which shows, clearly, the structural complexity printed in the area, mainly related to Carnaubais fault system, acting as an important fault system of the rift edge. This fault system is characterized by a main arrangement of normal faults with trend NE-SO, where Carnaubais Fault represents the maximum expression of these lineations. Carnaubais Fault corresponds to a fault with typically listric geometry, with general trend N70°E, dipping to northwest. It is observed, throughout all the seismic volume, with variations in its surface, which had conditioned, in its evolutive stages, the formation of innumerable structural features that normally are identified in Pendencia Formation. In this unit, part of these features is related to the formation of longitudinal foldings (rollover structures and distentional folding associated), originated by the displacement of the main fault plan, propitiating variations in geometry and thickness of the adjacent layers, which had been deposited at the same time. Other structural features are related to the secondary faultings, which could be synthetic or antithetic to Carnaubais Fault. In a general way, these faults have limited lateral continuity, with listric planar format and, apparently, they play the role of the accomodation of the distentional deformation printed in the area. Thus, the interaction between the stratigraphic and structural analysis, based on an excellent quality of the used data, allowed to get one better agreement on the tectonicsedimentary evolution of the Valanginian-Barremian interval (Pendência Formation) in the studied area
