Rediscovery of the syntypes of Corydoras meridionalis R. von Ihering, 1911 (Teleostei, Siluriformes, Callichthyidae) and designation of lectotype

Os síntipos de Corydoras meridionalis Rodolpho von Ihering, 1911, tidos como desaparecidos da coleção de peixes do Museu de Zoologia da USP, foram encontrados; os exemplares tinham sido identificados como C. ehrhardti Steindachner, 1910, espécie atualmente considerada sinônimo sênior da primeira. O exame desses sintipos permite confirmar a sinonímia proposta. Dados sobre os síntipos são apresentados e comparados com os dados das descrições originais de C. ehrhardti e C. meridionalis, sendo comentadas as poucas diferenças encontradas entre eles. É designado o lectótipo de C. meridionalis e uma fotografia deste é apresentada.

Associação entre o índice de massa corporal de pais e de escolares de 7 a 14 anos de Florianópolis, SC, Brasil

OBJETIVOS: verificar a associação entre o Índice de Massa Corporal (IMC) de escolares de 7 a 14 anos e dos respectivos pais. MÉTODOS: estudo transversal com 886 escolares de quatro escolas de Florianópolis, SC. Diagnóstico antropométrico dos escolares e dos pais definido, respectivamente, a partir do IMC para idade de acordo com Centers for Disease Control and Prevention e dos pontos de corte da Organização Mundial da Saúde. A associação entre o IMC dos pais e dos escolares foi estimada por meio da razão de prevalência (RP) com intervalo de confiança (IC) de 95% e teste qui-quadrado com valor de significância de p< 0,05. RESULTADOS: identificou-se prevalência de sobrepeso/obesidade mais elevada em meninos (29,9%) quando comparada a de meninas (17,7%) (p<0,001). Observou-se relação estatisticamente significante entre o IMC de escolares do sexo feminino com o IMC das mães (RP=1,63; IC95%=1,1-3,0; p=0,02) e dos pais (RP=1,78; IC95%= 1,1-3,5; p=0,01). Nos escolares do sexo masculino a associação observada não foi estatisticamente significante. CONCLUSÕES: identificou-se que a prevalência do sobrepeso ou obesidade é 1,63 vezes maior, entre as meninas, quando a mãe também apresenta esse distúrbio e 1,78 vezes maior quando o pai o apresenta, em comparação a mães e pais eutróficos ou de baixo peso.

Antropometria de idosos residentes no município de Joinville-SC, Brasil

Objetivo: Fornecer dados antropométricos de idosos residentes na área urbana do município de Joinville, SC. Metodologia: Foram analisados 218 idosos com idade igual ou superior a 60 anos, de ambos os sexos, não institucionalizados e residentes na área urbana da cidade de Joinville-SC, no ano de 2002. Os idosos foram apresentados segundo sexo e grupo etário: 60-69 anos, 70-79 anos e 80 e mais. As variáveis antropométricas foram apresentadas sob a forma de média, desvio-padrão e percentil (P5, P10, P25, P50, P75, P90 e P95). Resultados: Dos 218 idosos, 130 (59,6%) foram mulheres e 88 (40,4%) homens. Apesar de os valores médios da maioria das variáveis investigadas sugerirem uma tendência a diminuir com o aumento da idade, não houve diferença estatisticamente significativa dos valores médios entre os grupos etários para ambos os sexos (p>0,05). Quando comparados por sexo, os valores médios de IMC, CQ e DCT das mulheres foram significativamente superiores aos dos homens. Estes, em contrapartida, apresentaram valor médio da CC significativamente superior ao das mulheres (p<0,05). Conclusão: A maioria dos estudos realizados com idosos em outros países tem investigado esta categoria considerando pessoas com idade igual ou superior a 65 anos, o que dificulta a comparação com os dados brasileiros. Somado a outros estudos realizados com idosos no Brasil, os dados obtidos neste estudo podem contribuir para a construção de um padrão antropométrico da população idosa brasileira, ainda inexistente no país

Síndrome de burnout em professores do ensino médio de escolas pertencentes à gerência regional de educação e inovação (GEREI) do município de tubarão (SC)

Este artigo baseia-se em dissertação de mesmo título, apresentada à Universidade do Sul de Santa Catarina. Tem por objetivo estimar a prevalência da síndrome de burnout em professores do Ensino Médio da rede pública estadual em Tubarão (SC). Um grupo de 101 professores de sete Escolas de Ensino Médio, com atividades em sala de aula, responderam a um questionário de dados sociodemográficos e funcionais e ao Maslach burnout inventory - educators survey. Verificou-se a existência de correlação entre os escores fatoriais das três dimensões da síndrome de burnout e as variáveis independentes. A prevalência da síndrome de burnout foi de 12,9%. Encontrou-se correlação positiva entre tempo de serviço e a dimensão Despersonalização (r=0,2101; p=0,035), bem como entre a dimensão Despersonalização e a situação funcional (r =0,2929; p=0,003). Os resultados indicam alta chance de desenvolvimento de burnout ou burnout em curso. A adoção de medidas de promoção à saúde mental dos professores poderia evitar a despersonalização entre professores observada nesse estudo

Transiting exoplanets from the CoRoT space mission XII. CoRoT-12b: a short-period low-density planet transiting a solar analog star

We report the discovery by the CoRoT satellite of a new transiting giant planet in a 2.83 days orbit about a V = 15.5 solar analog star (M(*) = 1.08 +/- 0.08 M(circle dot), R(*) = 1.1 +/- 0.1 R(circle dot), T(eff) = 5675 +/- 80 K). This new planet, CoRoT-12b, has a mass of 0.92 +/- 0.07 M(Jup) and a radius of 1.44 +/- 0.13 R(Jup). Its low density can be explained by standard models for irradiated planets.

Crystallite size-dependent phases in nanocrystalline ZrO(2)-Sc(2)O(3)

ZrO(2)-10, 12 and 14 mol% Sc(2)O(3) nanopowders were prepared by using a nitrate-lysine gel-combustion synthesis. These materials were studied by synchrotron X-ray powder diffraction (SXPD) and Raman spectroscopy after calcination at different temperatures from 650 to 1200 degrees C, which led to samples with different average crystallite sizes, up to about 100 nm. The results from SXPD and Raman analyses indicate that, depending on Sc(2)O(3) content, the metastable t ''-form of the tetragonal phase or the cubic phase are fully retained at room temperature in nanocrystalline powders, provided an average crystallite sizes lower than similar to 30 nm. By contrast, powders with larger average crystallite sizes exhibit the stable rhombohedral, beta and gamma, phases and do not retain or very partially retain the metastable t '' and cubic ones.

BEM formulation for von Karman plates

This work deals with nonlinear geometric plates in the context of von Karman`s theory. The formulation is written such that only the boundary in-plane displacement and deflection integral equations for boundary collocations are required. At internal points, only out-of-plane rotation, curvature and in-plane internal force representations are used. Thus, only integral representations of these values are derived. The nonlinear system of equations is derived by approximating all densities in the domain integrals as single values, which therefore reduces the computational effort needed to evaluate the domain value influences. Hyper-singular equations are avoided by approximating the domain values using only internal nodes. The solution is obtained using a Newton scheme for which a consistent tangent operator was derived.

Residuals for log-Burr XII regression models in survival analysis

In this paper, we compare three residuals to assess departures from the error assumptions as well as to detect outlying observations in log-Burr XII regression models with censored observations. These residuals can also be used for the log-logistic regression model, which is a special case of the log-Burr XII regression model. For different parameter settings, sample sizes and censoring percentages, various simulation studies are performed and the empirical distribution of each residual is displayed and compared with the standard normal distribution. These studies suggest that the residual analysis usually performed in normal linear regression models can be straightforwardly extended to the modified martingale-type residual in log-Burr XII regression models with censored data.

von Wright`s Therapy to Jorgensen`s Syndrome

In his last papers about deontic logic, von Wright sustained that there is no genuine logic of norms. We argue in this paper that this striking statement by the father of deontic logic should not be understood as a death sentence to the subject. Rather, it indicates a profound change in von Wright`s understanding about the epistemic and ontological role of logic in the field of norms. Instead of a logical constructivism of deontic systems revealing a necessary structure of prescriptive discourse, which marked his earlier efforts, he adopted the view that such systems should be seem as mere objects of comparison, i.e. as providing practical standards of rationality for norm-giving activity. Within such view he proposed an interpretation of standard deontic logic in such a way to free deontic logicians from the philosophical difficulties related to the so-called Jorgensen`s dilemma and deontic paradoxes. This effort, as we claim in the present paper, is an application of Wittgenstein`s therapeutic method to dissolve philosophical difficulties caused by the use of logical tools to model relations between norms.

Evaluation of the Importance of Attributes in Customer Satisfaction with Supermarkets in the Mid-Valley Region of the Itajai - SC

In a dynamic atmosphere of competitiveness, customer satisfaction is a key factor in the long term success of a business relationship. From this perspective, the objective of the article was to evaluate the importance of attributes and customer satisfaction with Supermarkets in the Mid-Valley region of the ltajai/SC. Research methodology is characterized as descriptive, of the survey type, with a quantitative, cross section approach. The research instrument used was a questionnaire structured with open and closed questions, according to Lickert`s scale. By means of this, the degree of importance of supermarket attributes and the level of customer satisfaction with them were verified. In regard to the importance of the attributes, cleaning, parking, safety and variety of products are the most important, while the attributes Of purchase through the internet and taste samples are the least significant ones. The results of satisfaction point to the fact that the Supermarkets Big and Angeloni presented a greater degree of satisfaction in relation to the general average in practically all of the attributes, while Bistek presented the smallest degree of satisfaction, only surpassing the average in regard to the attribute of store lighting.

Identification of novel mutations of the WFS1 gene in Brazilian patients with Wolfram syndrome

Objective: Wolfram syndrome (WS) is a rare, progressive, neurodegenerative disorder with an autosomal recessive pattern of inheritance. The gene for WS, WFS1, was identified on chromosome 4p16 and most WS patients carry mutations in this gene. However. some studies have provided evidence for genetic heterogeneity and the genotype-phenotype relationships are not clear. Our aim was to ascertain the spectrum of WFS1 mutations in Brazilian patients with WS and to examine the phenotype-genotype relationships in these patients. Design and methods: Clinical characterization and analyses of the WFS1. gene were performed in 27 Brazilian patients with WS from 19 families. Results: We identified 15 different mutations in the WFS1 gene in 26 patients, among which nine are novel. All mutations occurred in exon 8, except for one missense mutation which was located in exon 5. Although we did not find any clear phenotype-genotype relationship in patients with mutations in exon 8, the homozygous missense mutation in exon 5 was associated with a mild phenotype: onset of diabetes mellitus and optic atrophy during adulthood with good metabolic control being achieved with low doses of sulfonylurea Conclusions: Our data show that WFS1 is the major gene involved in WS in Brazilian patients and most mutations are concentrated in exon 8. Also, our study increases the spectrum of WFS1 mutations. Although no clear phenotype-genotype relationship was found for mutations in exon 8, a mild phenotype was associated with a homozygous missense mutation in exon 5.
