Graduates' perceptions about the acquired clinical competences in undergraduate study of medicine in National University of the Northeast, UNNE, Argentina
El objetivo de la investigación es evaluar la calidad y pertinencia de la educación médica impartida en la Carrera de Medicina de la Universidad Nacional del Nordeste (Argentina), a través del estudio de las percepciones de los graduados, con respecto a: la educación médica recibida, las competencias clínicas adquiridas y la adecuación de la formación a las actuales exigencias de la profesión médica. Se compara, además, el perfil real de los graduados con el perfil profesional ideal de la Carrera de Medicina, que define las competencias clínicas a desarrollar para formar un médico general, según el modelo curricular establecido. El estudio se basa en una encuesta a 439 graduados, de hasta diez años de egreso, de la ciudad de Corrientes (Argentina). Según los resultados obtenidos, los graduados evaluaron, en la educación médica recibida, como satisfactorios, principalmente, aspectos tradicionales (ej. formación teórica). Y, consecuentemente, se consideraron mejor capacitados en competencias médicas tradicionales (diagnósticas o exploratorias) y menos formados en las nuevas competencias, que hoy se exigen a los médicos (ej. trabajo en equipo). Significativamente, los graduados hicieron evaluaciones diferenciales sobre la formación, privilegiando los contextos de prácticas de mayor interacción con pacientes. A partir del estudio, podría sostenerse que en los procesos de modernización y cambio curricular de la educación médica, es fundamental, por una parte, la coherencia entre objetivos institucionales, perfil profesional propuesto y modelo curricular implementado. Pero, además, poseen una particular importancia los contextos de aprendizaje y las funciones centralizadoras de los docentes, como responsables de los procesos de socialización, a través de los cuales los jóvenes adquieren conocimientos, actitudes y valores, que condicionarán significativamente el modelo médico que efectivamente se forma.The investigation intends to evaluate the quality and pertinence relevancy of the medical education, in the Career of Medicine of the National University of the Northeast (Argentina), according to the perceptions of the graduate ones, about: the received medical education, the acquired clinical competences and the adaptation of the medical formation to the demands of the profession, in the current systems of health. The real profile of the graduate ones is compared with the ideal profile of the Career of grade Medicine, where they are defined the clinical competences to develop in a general physician. A survey was applied at 439 graduate, of up to ten years of expenditure, of the city of Corrientes (Argentina). The results show that: the graduate ones considered "satisfactory", preferably, traditional aspects of the education, for example, the theoretical teaching and the used methods. Consequently, they were considered they are better qualified in traditional medical competences, as the diagnostic ones (that continue being central in the current medical education) and the initial physical explorations and anamnesis. Of the data it is possible to infer that, in the modernization processes and curricular change, it is fundamental the coherence among the proposed professional profile - ideal - and the curricular model implemented in the career, to achieve such purposes. Also, it is evidenced in the graduate, examined, the preponderant rol of the teacher one, in the transmission of knowledge and skills and, mainly, in the formation of values and attitudes about the medical model that transmits.Fil: Humberto, Blanca Rosa.

Identifying and correcting oblique striping in the topodata digital elevation model.
The Topodata digital elevation model (DEM) is the best DEM available for digital soil mapping (DSM) in Brazil. However, it is not ready to use. We show that the kriging interpolator used to downscale the SRTM DEM from 3 arc-seconds to 1 arc-second spatial resolution increased the double oblique striping (15º and 60º) so common to SRTM DEMs. This is because kriging is quite sensitive to outliers. Besides, the Gaussian model of spatial covariance used in the downscaling enhanced the sensitivity of kriging to outliers, thus enhancing the striping. 2D Fast Fourier Transform can be used to identify whether a destriping procedure need to be employed. The bilinear or cubic resampling methods should be used to warp Topodata DEMs because they are insensitive to the double oblique striping
Em direção a uma ciência do solo mais aberta.
Os que trabalham com ciências ambientais como a Ciência do Solo sabem que esse métier envolve a avaliação de múltiplas variáveis ambientais descritivas e explicativas. O intuito é compreender os complexos fenômenos que ocorrem na natureza, seja trabalhando no campo ou em laboratório, ou ainda com seus derivados, como a micro, meso ou macrobiota. Assim, nossas pesquisas geralmente geram enormes planilhas de dados, com resultados de diversas variáveis, muitas delas medidas ao longo do tempo. Estas são frequentemente analisadas usando métodos estatísticos complexos, a fim de encontrar e explorar as relações entre as variáveis e sua significância. Dentre esses métodos, os multivariados se tornaram indispensáveis por serem muito úteis para revelar essas relações de maneira visualmente compreensível. Contudo, uma limitação da quase totalidade dos trabalhos de pesquisa em Ciência do Solo realizados no Brasil é a ausência de acesso aos dados primários usados nas análises estatísticas. Isso impede o reuso dos dados, seja para reproduzir um estudo e verificar suas conclusões ou para realizar novas pesquisas para responder questões que ficaram sem respostabitstream/item/222244/1/George-Brown-Em-direcao-a-uma-Ciencia-do-Solo-mais-aberta.pd
Open legacy soil survey data in Brazil: geospatial data quality and how to improve it.
Spatial soil data applications require sound geospatial data including coordinates and a coordinate reference system. However, when it comes to legacy soil data we frequently find them to be missing or incorrect. This paper assesses the quality of the geospatial data of legacy soil observations in Brazil, and evaluates geospatial data sources (survey reports, maps, spatial data infrastructures, web mapping services) and expert knowledge as a means to fix inconsistencies. The analyses included several consistency checks performed on 6,195 observations from the Brazilian Soil Information System. The positional accuracy of geospatial data sources was estimated so as to obtain an indication of the quality for fixing inconsistencies. The coordinates of 20 soil observations, estimated using the web mapping service, were validated with the true coordinates measured in the field. Overall, inconsistencies of different types and magnitudes were found in half of the observations, causing mild to severe misplacements. The involuntary substitution of symbols and numeric characters with similar appearance when recording geospatial data was the most common typing mistake. Among the geospatial data sources, the web mapping service was the most useful, due to operational advantages and lower positional error (~6 m). However, the quality of the description of the observation location controls the accuracy of estimated coordinates. Thus, the error of coordinates estimated using the web mapping service ranged between 30 and 1000 m. This is equivalent to coordinates measured from arc-seconds to arc-minutes, respectively. Under this scenario, the feedback from soil survey experts is crucial to improving the quality of geospatial data
Elasticity of semiflexible polymers with and without self-interactions
A {\it new} formula for the force vs extension relation is derived from the
discrete version of the so called {\it worm like chain} model. This formula
correctly fits some recent experimental data on polymer stretching and some
numerical simulations with pairwise repulsive potentials. For a more realistic
Lennard-Jones potential the agreement with simulations is found to be good when
the temperature is above the temperature. For lower temperatures a
plateau emerges, as predicted by some recent experimental and theoretical
results, and our formula gives good results only in the high force regime. We
briefly discuss how other kinds of self-interactions are expected to affect the
elasticity of the polymer.Comment: 8 pages, 10 figure
Longitudinal Secretion of Paramyxovirus RNA in the Urine of Straw-Coloured Fruit Bats (Eidolon helvum).
The straw-coloured fruit bat (Eidolon helvum) is widespread in sub-Saharan Africa and is widely hunted for bushmeat. It is known to harbour a range of paramyxoviruses, including rubuloviruses and henipaviruses, but the zoonotic potential of these is unknown. We previously found a diversity of paramyxoviruses within a small, captive colony of E. helvum after it had been closed to contact with other bats for 5 years. In this study, we used under-roost urine collection to further investigate the paramyxovirus diversity and ecology in this colony, which had been closed to the outside for 10 years at the time of sampling. By sampling urine weekly throughout an entire year, we investigated possible seasonal patterns of shedding of virus or viral RNA. Using a generic paramyxovirus L-gene PCR, we detected eight distinct paramyxovirus RNA sequences. Six distinct sequences were detected using a Henipavirus-specific PCR that targeted a different region of the L-gene. Sequence detection had a bi-annual pattern, with the greatest peak in July, although different RNA sequences appeared to have different shedding patterns. No significant associations were detected between sequence detection and birthing season, environmental temperature or humidity, and no signs of illness were detected in any of the bats in the colony during the period of sample collection
The fast declining Type Ia supernova 2003gs, and evidence for a significant dispersion in near-infrared absolute magnitudes of fast decliners at maximum light
We obtained optical photometry of SN 2003gs on 49 nights, from 2 to 494 days
after T(B_max). We also obtained near-IR photometry on 21 nights. SN 2003gs was
the first fast declining Type Ia SN that has been well observed since SN
1999by. While it was subluminous in optical bands compared to more slowly
declining Type Ia SNe, it was not subluminous at maximum light in the near-IR
bands. There appears to be a bimodal distribution in the near-IR absolute
magnitudes of Type Ia SNe at maximum light. Those that peak in the near-IR
after T(B_max) are subluminous in the all bands. Those that peak in the near-IR
prior to T(B_max), such as SN 2003gs, have effectively the same near-IR
absolute magnitudes at maximum light regardless of the decline rate Delta
m_15(B).
Near-IR spectral evidence suggests that opacities in the outer layers of SN
2003gs are reduced much earlier than for normal Type Ia SNe. That may allow
gamma rays that power the luminosity to escape more rapidly and accelerate the
decline rate. This conclusion is consistent with the photometric behavior of SN
2003gs in the IR, which indicates a faster than normal decline from
approximately normal peak brightness.Comment: 41 pages, 13 figures, to be published in the December, 2009, issue of
