Abstract: This article describes the experience of virtualizing an presential course, so the results of its usability. In 2009 began the process of virtualizing the subject: Writing Tools for Researchers in Health. The course was redesigned based on ASSURE model instructional plan. It involved the audience’s characteristics and skills analysis regarding to the use of ICT, as well as objective changing, means, methods, materials, and new strategies of learning assessment, so the virtual classroom edition on Moodle platform. Once the course was redesigned, it was offered to 17 professors of the Faculty of Health Science at University Lisandro Alvarado, who were professors and counselors in nursing research having ICT skills. The study found that participants thought that this mode was relevant, due to its efficacy as tutors’ labor. So, it is highly recommend to some other colleagues.
A emenda constitucional n. 29 de 2000 e os governos estaduais
Fortes, Fátima Beatriz;
Lua Nova: Revista de Cultura e Política , 2012, DOI: 10.1590/S0102-64452012000300008
Abstract: the purpose of this paper is to investigate the effects of constitutional amendment 29 (ec n.29), of 2000, on the decisions of state governors related to the allocation of funds for the health sector, aiming at identifying its conditioning factors. the results of the adjusted model showed that the variable amendment indicating the passing of ec n. 29 was highly significant, confirming that its passing induced governors to raise the revenue percentage invested in the health sector. among context-related variables, just the net per capita revenue and the ideological profile of the governor′s party were significant. however, the overall results allow to state that such variables only marginally condition the substantial effect of the amendment on the states. what can be concluded is that the introduction of a rule such as ec n. 29 was capable of inducing governors to adopt behaviors despite the context-related variables considered herein.

A KNN Undersampling Approach for Data Balancing  [PDF]
Marcelo Beckmann, Nelson F. F. Ebecken, Beatriz S. L. Pires de Lima
Journal of Intelligent Learning Systems and Applications (JILSA) , 2015, DOI: 10.4236/jilsa.2015.74010
Abstract: In supervised learning, the imbalanced number of instances among the classes in a dataset can make the algorithms to classify one instance from the minority class as one from the majority class. With the aim to solve this problem, the KNN algorithm provides a basis to other balancing methods. These balancing methods are revisited in this work, and a new and simple approach of KNN undersampling is proposed. The experiments demonstrated that the KNN undersampling method outperformed other sampling methods. The proposed method also outperformed the results of other studies, and indicates that the simplicity of KNN can be used as a base for efficient algorithms in machine learning and knowledge discovery.
Harmonic Analysis in Discrete Dynamical Systems  [PDF]
Gerardo Pastor, Miguel Romera, Amalia Beatriz Orue, Agustin Martin, Marius F. Danca, Fausto Montoya

Abstract: In this paper we review several contributions made in the field of discrete dynamical systems, inspired by harmonic analysis. Within discrete dynamical systems, we focus exclusively on quadratic maps, both one-dimensional (1D) and two-dimensional (2D), since these maps are the most widely used by experimental scientists. We first review the applications in 1D quadratic maps, in particular the harmonics and antiharmonics introduced by Metropolis, Stein and Stein (MSS). The MSS harmonics of a periodic orbit calculate the symbolic sequences of the period doubling cascade of the orbit. Based on MSS harmonics, Pastor, Romera and Montoya (PRM) introduced the PRM harmonics, which allow to calculate the structure of a 1D quadratic map. Likewise, we review the applications in 2D quadratic maps. In this case both MSS harmonics and PRM harmonics deal with external arguments instead of with symbolic sequences. Finally, we review pseudoharmonics and pseudoantiharmonics, which enable new interesting applications.
Efeitos do alumínio sobre o desenvolvimento e a composi??o mineral de quatro leguminosas forrageiras tropicais

Abstract: with respect to the differential tolerance beyween the species, the following was observed: a) stylosanthes and galactia were shown to. be more tolerant. in fact, the highest dry matter production in the case of the latter took place in the presence of 5 ppm of al; growth was not affected by the higher levels of the element. stylosanthes did not show toxicity symptoms, maximum growth occuring in the presence of 20 ppm of al in the nutrient soluction. b) both glycine and macroptilium proved to be sensitive. lower levels of al increased growth of the former; its dry matter yield, however, decreased when the element was given at the levels of 20 ppm. the growth of macroptilium was reduced by 20 ppm of al. glycine showed toxicity symptons. especially in the root system which was seriously damaged by thehi gher al level. c) al additions caused decrease in the concentration of p, ca, mg and mn in the roots and or in the tops. the al of the root system was increased.
Efeitos do manganês sobre o desenvolvimento e a composi??o mineral de quatro leguminosas forrageiras tropicais

Abstract: four tropical forage legumes (galactia striata. glycine wightii, macroptilium atropurpureum and stylosanthes guianensis), were grown in nutrient solution under varying levels of manganese (0., 25, 50 e 100 ppm). with respect to the differential tolerance between the species, the following was observed: a) stylosanthes was not affected neither in therms of growth nor in terms of symptons of toxicity. galactia was realtively less tolerant: its growth was significantly reduced by 100 ppm of mn in the substrate which also caused severe toxicity symptons. b) glycine and macroptilium were sensitive to high mn. growth of the former was decreased by 25 ppm, being not further reduced by higher concentrations. the mn concentration of 50 ppm caused the highest reduction of the growth of macroptilium. toxicity symptoms were more acute in the case of glycine. c) the addition of mn induced a decrease in the content of k, ca and mg. the levels of cu and zn in the tops decreased whereas the mn concentration increased in the whole plant.
Os livros didáticos e o ensino para a saúde: o caso das drogas psicotrópicas
Carlini-Cotrim,Beatriz; Rosemberg,Fúlvia;
Revista de Saúde Pública , 1991, DOI: 10.1590/S0034-89101991000400009
Abstract: eighteen didactic books on sciences/biology, civic and moral education and brazilian political and social studies, for primary and secondary schools, were analyzed, with a view to assessing the way in which the issue of psychotropic drug use is dealt with. the texts analyzed are structurally centered on the discussion of the harmful effects of drugs instead of discussing others topics (such as etiology, concepts, treatment, incidence and prevalence). the texts are characterized especially by the use of non-scientific language in which emotional appeal and an exceedingly exacerbated style are the rule. the drug user is described as being necessarily a moral, physical and psychological decadent. the results were discussed in the light of recent theories on the prevention of drug abuse.
Sistema de vigilancia epidemiológica de la violencia para los municipios colombianos
Duque,Luis F; Caicedo,Beatriz; Sierra,Clara;
Revista Facultad Nacional de Salud Pública , 2008,
Abstract: the different systems of epidemiological surveillance of injuries and violence proposed by colombian and international institutions are analyzed. the fact that those systems do not provide enough information on non fatal injuries, characteristics of the aggressors nor protection factors of the different forms of violence is emphasized. a system based on information which should be gathered at a small scale according to legal rules is proposed. this information should also be underreported (violent deaths, suicide, deaths due to traffic accidents, and non fatal injuries). the implementation of periodic and systematic community surveys is also suggested, designed in different formats according to the local circumstances of the municipalities. the magnitude and distribution of the different forms of violence and other risky behaviors generally linked to such violence, as well as the protection and risk factors are all monitored through the surveys mentioned above. the system proposed here does not replace the surveillance systems legally adopted by colombian norms, but it does reinforce and complement them.
