Desvelando a relação entre ideologia, valores do indivíduo e estilo de consumo

This article aims to answer the question about the relationship between the values of an individual and their frequency of consumption. It develops a discussion on the theoretical and conceptual term “value”, on the formation of individualistic ideology and consumer society. For empirical verification, it applies three questionnaires validated in the literature to measure cultural values (ideologies), individual values and frequency of consumption in a population of 226 subjects. On the basis of the use of multivariate techniques of data analysis (correlations, regression and structural equations) and theoretical support, it was possible to coin the term “social elected”, meaning individuals who seek, on the basis of consumption, to demonstrate to society power, authority and status, independently of groups, legitimated by the values of freedom and equality, which guarantee that all can pursue the same condition of elected.Key words: values, individualism, consumption, social elected, structural equations.Este artigo pretende responder qual a relação entre os valores do indivíduo e sua frequência de consumo. Para isso, desenvolve-se uma discussão teórico-conceitual sobre o termo valor, sobre a formação da ideologia individualista e da sociedade de consumo. Para verificação empírica, aplicam-se três questionários validados na literatura, para medir valores culturais (ideologias), valores individuais e frequência de consumo em uma população de 226 elementos. A partir da utilização de técnicas multivariadas de análise de dados (correlações, regressão e equações estruturais) e com respaldo teórico, foi possível cunhar o termo eleito social, ou seja, indivíduos que buscam, a partir do consumo, demonstrar, diante da sociedade, poder, autoridade e status, independentemente de grupos, legitimados pelos valores liberdade e igualdade, que garantem a todos buscar a mesma condição de eleito.Palavras-chave: valores, individualismo, consumo, eleito social, equações estruturais

PARSEC PARAMETERIZATION METHODOLOGY FOR ENHANCING AIRFOILS GEOMETRY USING PSO ALGORITHM

The electromechanical generating system is mainly based on the characteristics wherein the turbine has to ”harvest” the energy of a working fluid. Thus, the engineering behind the blades, such as the geometry and construction, must be effectively consolidated to increase the overall turbine efficiency. This work aims to go further into the computational principles of modeling the turbine blades, precisely, the hydrokinetic turbine hydrofoil built by LEA (Engineering Laboratory and Environment - UNB). The study has a focus on designing and analyzing, through numerical studies of parameterization and optimization profiles, blades using computational tools such as MATLAB R2016b and XFOIL. In this case, the model study is part of the airfoil theory combined with the Particle Swarm Optimization technic (PSO), which are implemented to get a maximum utilization of the aerodynamic coefficient CL over CD of the blade. Furthermore, an optimal turbine blade geometry, set by PARSEC parameter, is found and compared with results obtained from the original hydrofoil, using the software of profile analysis XFOIL, to certify the mathematical method, proving its effectiveness to parameterize hydrodynamic profiles and optimize their geometries.Keywords: Hydrokinetic Turbine.

Understanding the clinical spectrum of complicated Plasmodium vivax malaria: a systematic review on the contributions of the Brazilian literature

The resurgence of the malaria eradication agenda and the increasing number of severe manifestation reports has contributed to a renewed interested in the Plasmodium vivax infection. It is the most geographically widespread parasite causing human malaria, with around 2.85 billion people living under risk of infection. The Brazilian Amazon region reports more than 50% of the malaria cases in Latin America and since 1990 there is a marked predominance of this species, responsible for 85% of cases in 2009. However, only a few complicated cases of P. vivax have been reported from this region. A systematic review of the Brazilian indexed and non-indexed literature on complicated cases of vivax malaria was performed including published articles, masters' dissertations, doctoral theses and national congresses' abstracts. The following information was retrieved: patient characteristics (demographic, presence of co-morbidities and, whenever possible, associated genetic disorders); description of each major clinical manifestation. As a result, 27 articles, 28 abstracts from scientific events' annals and 13 theses/dissertations were found, only after 1987. Most of the reported information was described in small case series and case reports of patients from all the Amazonian states, and also in travellers from Brazilian non-endemic areas. The more relevant clinical complications were anaemia, thrombocytopaenia, jaundice and acute respiratory distress syndrome, present in all age groups, in addition to other more rare clinical pictures. Complications in pregnant women were also reported. Acute and chronic co-morbidities were frequent, however death was occasional. Clinical atypical cases of malaria are more frequent than published in the indexed literature, probably due to a publication bias. In the Brazilian Amazon (considered to be a low to moderate intensity area of transmission), clinical data are in accordance with the recent findings of severity described in diverse P. vivax endemic areas (especially anaemia in Southeast Asia), however in this region both children and adults are affected. Finally, gaps of knowledge and areas for future research are opportunely pointed out

Immediate extubation in cardiac surgery: evaluation using electroencephalogram Extubação imediata em cirurgia cardíaca: avaliação pelo eletroencefalograma

BACKGROUND AND OBJECTIVES:The current techniques of anesthesia employed in cardiac surgery leading to immediate extubation depend on adequate analgesia and titration of anesthetic drugs. We sought to determine the best possible moment of extubation, using the bispectral index of the electroencephalogram. METHOD: Twelve ASA III patients were analyzed. Seven (58.4%) were children (Group I), submitted to correction of congenital cardiac defects with ages ranging from 0 to 7 years. Five adults (Group II), with ages ranging from 30 to 75 years, underwent coronary artery bypass grafts. In Group I spinal anesthesia (L5-S1) using hyperbaric 0.5% bupivacaine (0.5mg/kg) and morphine (5µg/kg) was chosen. In Group II epidural anesthesia (T3-T4) with catheter placement plus ropivacaine (60mg) and morphine (2mg) were employed. For the induction of anesthesia fentanila (4µg/kg), muscle relaxant and propofol (to bring the bispectral index value down to 30) were utilized. General anesthesia was maintained with sevofluorane, maintaining the bispectral index value between 40 and 60. Extubation was programmed at a bispectral index value of 90. RESULTS: All patients were extubated up to one hour after the end of the surgical procedure, 91.6% of them in the operating room. All had the cognitive functions preserved without history of explicit memory or pain (adults and children who were able to speak), nor facial expression of pain (small children). Four (57%) patients in Group I and one (20%) in Group II had post-operative pruritus. Two patients (28%) in Group II had emesis. CONCLUSIONS: The results suggest that the technique employed is safe and effective, as long as the criteria for its use are strictly observed.<br>INTRODUÇÃO: As técnicas empregadas em cirurgia cardíaca visando a extubação imediata (EI) dependem de analgesia adequada e titulação de drogas anestésicas. OBJETIVO: A finalidade deste estudo é analisar a EI, utilizando eletroencefalograma (índice bispectral - BIS) para adequar o melhor momento de extubação. MÉTODO: Foram analisados 12 pacientes, ASA III, 7 crianças (Grupo I) 58,4%, com idades entre 0 e 7 anos, submetidas a correção cirúrgica de cardiopatias congênitas e 5 adultos (Grupo II), com idades entre 30 e 75 anos, submetidos a revascularização do miocárdio. No Grupo I realizou-se raquianestesia entre L5 e S1 com injeção de marcaína pesada (0,5 mg/kg) e morfina (5µg/kg). No Grupo II realizou-se bloqueio epidural entre T3 e T4, com introdução de cateter e injeção de 60mg de ropivacaína e 2mg de morfina. Na indução da anestesia, empregamos: Fentanil 4 µg/kg, propofol até BIS igual a 30 e relaxante muscular. A anestesia geral foi mantida com sevoflurano para BIS entre 40 e 60. Foi programada extubação quando o BIS atingisse 90. RESULTADOS: Todos os pacientes foram extubados até 1 hora após o término da operação, sendo 91,6% na sala de operações, com função cognitiva preservada, sem história de memória explícita, dor (adultos e crianças maiores) ou expressão facial de dor (crianças menores). Cinqüenta e sete por cento (4) dos pacientes do Grupo I e 20% (1) Grupo II apresentaram prurido e 28% (2) Grupo I apresentaram vômitos. CONCLUSÕES: A técnica empregada mostrou-se segura e eficaz, desde que observados critérios rígidos para sua execução
