Análise dos marcos teóricos e estruturais do currículo de graduação em enfermagem no Rio Grande do Norte

This research had as its guiding question: what theoretical and structural milestone of graduation nursing curriculum of public universities in the State of Rio Grande do Norte? The objectives of this study were: Analyze theoretical and structural milestones of graduation nursing curriculum of public universities in the State of Rio Grande do Norte; Identify the theoretical milestone and training models that guide the structural milestones of nursing curriculum courses of public universities studied; Analyze the training concepts of curriculums from the voices of the coordinators of the courses. This is a qualitative study, analytical, with discussions of the documentary and empirical research. Ten teachers participated who act as coordinators of the graduation courses in nursing or academic advisors, in UFRNCentral Campus in Natal and Health Sciences College (Facisa), in Santa Cruz-and on UERN -Campus Caicó, Mossoró and Pau dos Ferros. The information collected by interview was analyzed by sociology or symbolic cartography of Boaventura de Sousa Santos. The research was approved by the Research Ethics Committee of the UERN by the CAAE: 03610912.7.0000.5294. All the participants signed the Free Consent and clarified Term The results and discussion were presented in four scientific articles. The first article, titled the Pedagogical projects in nursing analysis in the light of the symbolic cartography, features the use of cartographic method in the researches and in the study of nursing curriculums. In the article The Analysis of theoretical-philosophical, structural and referential milestones in nursing curriculums, these milestones are renowned in curriculums of UERN and UFRN. The main challenges faced in the implementation of supervised internship in nursing provide a reflection on the difficulties that the internship supervisors present, especially with the relationship between education/service and the articulation theory/practice. In the last article are discussed the changes in nursing training from the former student profile, who won a boost from the curricular changes proposed by the national curriculum guidelines. The study concluded, by the analysis of theoretical and structural milestones of nursing curriculum courses of public universities of Rio Grande do Norte, that there is an explicit intention to train nurses for the health system and a search on innovative teaching projects in accordance with the national curriculum guidelines for the area of nursing. The thesis defended in this investigation was that the curriculum of public institutions of higher education in nursing in the State of Rio Grande do Norte advanced from a training focusing on biologicist model, flexneriana guidelines, for teaching able to articulate the health with the social, political and cultural issues

Localização de um robô móvel usando odometria e marcos naturais

Several methods of mobile robot navigation request the mensuration of robot position and orientation in its workspace. In the wheeled mobile robot case, techniques based on odometry allow to determine the robot localization by the integration of incremental displacements of its wheels. However, this technique is subject to errors that accumulate with the distance traveled by the robot, making unfeasible its exclusive use. Other methods are based on the detection of natural or artificial landmarks present in the environment and whose location is known. This technique doesnt generate cumulative errors, but it can request a larger processing time than the methods based on odometry. Thus, many methods make use of both techniques, in such a way that the odometry errors are periodically corrected through mensurations obtained from landmarks. Accordding to this approach, this work proposes a hybrid localization system for wheeled mobile robots in indoor environments based on odometry and natural landmarks. The landmarks are straight lines de.ned by the junctions in environments floor, forming a bi-dimensional grid. The landmark detection from digital images is perfomed through the Hough transform. Heuristics are associated with that transform to allow its application in real time. To reduce the search time of landmarks, we propose to map odometry errors in an area of the captured image that possesses high probability of containing the sought mark

Os marcos da paisagem da cidade no contexto da trama urbana de Natal/RN: um estudo a partir do Morro do Careca, o Midway Mall, o Pórtico dos Reis Magos e a Ponte Newton Navarro

The present work is a study on the functions performed by landmarks landscape Natal / RN in the urban fabric, in the case of Midway Mall, the Portico dos Reis Magos, the Morro do Careca and Newton Navarro Bridge. For such goals established itself as analyze the functionality of the milestones presented here in the urban fabric; discuss the importance of these landmarks of the city landscape in the process of urbanization of Natal, and identify and spatialize actions related to the use of territories where are located landmarks, discussing their reflections. To achieve these goals we chose to use as a literature search procedures, the problematic concept, working with oral sources, and reading speechless. To support this research the main concepts were worked landscape, city, landmark, public space, circuits, among others. After going over the theory, consistent with the empirical data, it appears that the landmarks studied here have different functions and features, but all carry different forms of fascination for the public and visitors to the city, and every man your way, influence the public space, land speculation and feature importance in the process of urbanization of Natal

Marcos estratigraficos regionais na Formacao Palermo: caracterizacao dos picos radioativos

During a basinal scale study on Palermo Formation (Upper Permian, Parana Basin) high elevated Gamma Ray picks were identified mainly in the lower third of that stratigraphic unit. Those Gamma Ray signatures have been used as good regional stratigraphic markers. From them it was possible one chronostratigraphic analysis of Palermo Formation as pointed out by previous papers (Perinotto). Potassium40 is the responsible for the high Gamma Ray picks in the Palermo Formation. -from English summary

A comparison between diuretics and angiotensin-receptor blocker agents in patients with stage I hypertension (PREVER-treatment trial): Study protocol for a randomized double-blind controlled trial

Background: Cardiovascular disease is the leading cause of death in Brazil, and hypertension is its major risk factor. The benefit of its drug treatment to prevent major cardiovascular events was consistently demonstrated. Angiotensin-receptor blockers (ARB) have been the preferential drugs in the management of hypertension worldwide, despite the absence of any consistent evidence of advantage over older agents, and the concern that they may be associated with lower renal protection and risk for cancer. Diuretics are as efficacious as other agents, are well tolerated, have longer duration of action and low cost, but have been scarcely compared with ARBs. A study comparing diuretic and ARB is therefore warranted.Methods/design: This is a randomized, double-blind, clinical trial, comparing the association of chlorthalidone and amiloride with losartan as first drug option in patients aged 30 to 70 years, with stage I hypertension. The primary outcomes will be variation of blood pressure by time, adverse events and development or worsening of microalbuminuria and of left ventricular hypertrophy in the EKG. The secondary outcomes will be fatal or non-fatal cardiovascular events: myocardial infarction, stroke, heart failure, evidence of new subclinical atherosclerosis and sudden death. The study will last 18 months. The sample size will be of 1200 participants for group in order to confer enough power to test for all primary outcomes. The project was approved by the Ethics committee of each participating institution.Discussion: The putative pleiotropic effects of ARB agents, particularly renal protection, have been disputed, and they have been scarcely compared with diuretics in large clinical trials, despite that they have been at least as efficacious as newer agents in managing hypertension. Even if the null hypothesis is not rejected, the information will be useful for health care policy to treat hypertension in Brazil.

Prevention of hypertension in patients with pre-hypertension: Protocol for the PREVER-prevention trial

Background: Blood pressure (BP) within pre-hypertensive levels confers higher cardiovascular risk and is an intermediate stage for full hypertension, which develops in an annual rate of 7 out of 100 individuals with 40 to 50 years of age. Non-drug interventions to prevent hypertension have had low effectiveness. In individuals with previous cardiovascular disease or diabetes, the use of BP-lowering agents reduces the incidence of major cardiovascular events. In the absence of higher baseline risk, the use of BP agents reduces the incidence of hypertension. The PREVER-prevention trial aims to investigate the efficacy, safety and feasibility of a population-based intervention to prevent the incidence of hypertension and the development of target-organ damage.Methods: This is a randomized, double-blind, placebo-controlled clinical trial, with participants aged 30 to 70 years, with pre-hypertension. The trial arms will be chlorthalidone 12.5 mg plus amiloride 2.5 mg or identical placebo. The primary outcomes will be the incidence of hypertension, adverse events and development or worsening of microalbuminuria and of left ventricular hypertrophy in the EKG. The secondary outcomes will be fatal or non-fatal cardiovascular events: myocardial infarction, stroke, heart failure, evidence of new sub-clinical atherosclerosis, and sudden death. The study will last 18 months. The sample size was calculated on the basis of an incidence of hypertension of 14% in the control group, a size effect of 40%, power of 85% and P alpha of 5%, resulting in 625 participants per group. The project was approved by the Ethics committee of each participating institution.Discussion: The early use of blood pressure-lowering drugs, particularly diuretics, which act on the main mechanism of blood pressure rising with age, may prevent cardiovascular events and the incidence of hypertension in individuals with hypertension. If this intervention shows to be effective and safe in a population-based perspective, it could be the basis for an innovative public health program to prevent hypertension in Brazil.Trial Registration: Clinical Trials NCT00970931. © 2011 Fuchs et al; licensee BioMed Central Ltd.
