Liberdades possíveis em espaços periféricos: escravidão e alforria no termo da vila de Arez (séculos xviii e xix)

This paper discusses aspects of the slavery and emancipations in the village of Arez between the last quarter of the eighteenth century and the first decades of the nineteenth century. It seeks to identify the profile of the slaves and the emancipation possibilities in a peripheral region with few commercial activities, given that the most of the approaches about manumission consider towns and cities where the economic dynamics ware more pronounced, as places of higher possibilities of slaves working in diverse activities that allowed them to accumulate a reserve fund and thus buy their freedom. Therefore it was necessary to raise evidences of slavery in the case study, which was based on surveys of the eighteenth century, and the first decades of the nineteenth century and some population maps and civil records related to the early nineteenth century. The information about the manumission acts were analyzed based on writs of freedom registered in the village of Arez between 1774 and 1827 due to the absence of other documents about it. The registry books include all the documents of the Arez community; so, it was possible to observe what happened in rural localities, in the town, in the headquarters of the district and in the village of Goianinha. Based on information from the documents, it was possible to address some aspects of slavery like the predominant types of groups, the possible activities in which slaves were inserted and the profile of the freed slaves, the emancipation modes and, therefore, discuss the possible relations ship between the colonial space and manumissions and between masters and slaves

Mães de neonatos pré-termo hospitalizados: avaliação do apoio social e da sintomatologia ansiogênica

Social support is an important factor throughout one s life, especially in times of crisis. Premature delivery can be considered a crisis, followed by neonatal hospitalization. This type of birth is associated with elevated anxiety, representing risks to maternal mental health and mother-infant relationship. This research aims to investigate whether a relationship exists between perceived social support and the expression of anxiety in mothers of premature, hospitalized newborns. This is a cross-sectional, correlational study, conducted during the period of April to October 2011, using a convenience sample. The sample consisted of seventy mothers with preterm, hospitalized newborns and seventy mothers of full-term newborns. The instruments used were the State-Trait Anxiety Inventory and the Social Support Scale. The results demonstrated a weak negative relationship between intensity-State Anxiety and emotional support as well as a negative relationship in intensity between low to moderate-Trait Anxiety, social support and its dimensions (material support, emotional, information, interaction positive social and emotional). These suggest that the better the perception of social support, the less severe anxiogenic symptoms will be, and the converse is also true. It is noteworthy, therefore, the importance of social support, as well as the importance of health professionals to be aware not only of the physical health of the newborn, but also the psychosocial aspects that pervade the context of preterm birth followed by hospitalization

Utilizando Pesos estáticos e dinâmicos em sistemas multi-classificadores com diferentes níveis de diversidade

Although some individual techniques of supervised Machine Learning (ML), also known as classifiers, or algorithms of classification, to supply solutions that, most of the time, are considered efficient, have experimental results gotten with the use of large sets of pattern and/or that they have a expressive amount of irrelevant data or incomplete characteristic, that show a decrease in the efficiency of the precision of these techniques. In other words, such techniques can t do an recognition of patterns of an efficient form in complex problems. With the intention to get better performance and efficiency of these ML techniques, were thought about the idea to using some types of LM algorithms work jointly, thus origin to the term Multi-Classifier System (MCS). The MCS s presents, as component, different of LM algorithms, called of base classifiers, and realized a combination of results gotten for these algorithms to reach the final result. So that the MCS has a better performance that the base classifiers, the results gotten for each base classifier must present an certain diversity, in other words, a difference between the results gotten for each classifier that compose the system. It can be said that it does not make signification to have MCS s whose base classifiers have identical answers to the sames patterns. Although the MCS s present better results that the individually systems, has always the search to improve the results gotten for this type of system. Aim at this improvement and a better consistency in the results, as well as a larger diversity of the classifiers of a MCS, comes being recently searched methodologies that present as characteristic the use of weights, or confidence values. These weights can describe the importance that certain classifier supplied when associating with each pattern to a determined class. These weights still are used, in associate with the exits of the classifiers, during the process of recognition (use) of the MCS s. Exist different ways of calculating these weights and can be divided in two categories: the static weights and the dynamic weights. The first category of weights is characterizes for not having the modification of its values during the classification process, different it occurs with the second category, where the values suffers modifications during the classification process. In this work an analysis will be made to verify if the use of the weights, statics as much as dynamics, they can increase the perfomance of the MCS s in comparison with the individually systems. Moreover, will be made an analysis in the diversity gotten for the MCS s, for this mode verify if it has some relation between the use of the weights in the MCS s with different levels of diversity

O consentimento informado: Qual o seu real valor na prática médica?

Trata-se de um artigo que comenta sobre a real importância do Termo de Consentimento Informado na prática médica. Este documento tem sido cada vez mais usado como uma prática defensiva, a fim de constituir provas para defesa de um eventual processo judicial de responsabilidade médica, desvirtuando assim a idéia original, que seria a de respeitar a autonomia do paciente e delimitar a responsabilidade médica. O documento tem como objetivo mostrar que o médico cumpriu com seu dever de informar. Seu grande valor reside nos casos onde existam riscos de danos irreversíveis ao paciente. Conclui-se, porém, que um prontuário bem elaborado onde se inclui o registro das informações que foram transmitidas, bem como o grau de participação dos pacientes e seus familiares nas decisões terapêuticas, também deve ter valor ético e jurídico semelhante do TCI.

Crítica ao fundacionismo cartesiano com base no argumento contra a linguagem privada

This assignment ains to prove the pertinency of using the wittgenstein´s argument against private language as a criticism to cartesian fundacionism. Therefore, I want to demonstrate in the first chaper the conceptual viability of facing the cartesian argument of cogito not as a simple silogism but as an exemple of a private experience (process of thinking). At the second chaper, the subordination of the argument against private language give us the idea that rules can only be followed by means of corrections givem by a linguistic community that is external to the private subject, in a way to be unviable the assumption that is possible to name an internal experience without searching external rules of the use of terms. At the chaper 3 the pertinency of the hypothesis raised by A. Kenny, about the overtaking of the argument against private language can be extended to the idea of epistemic and ontologic privacy that would lend validity to the fundacion present at the argument at the cartesian cogito. In oder to become evident the pertinency of use of Wittgenstein´s argument agaist Descartes´ fundation, it´s necessary, at the chaper 3, to demonstrate the impertinency of the objection to the A. Kenny´s hypothesis, based on the experiency of the thought of the brain at the recipient, to make clear the incompatibility existing between the cartesian idea of cogito and Wittgenstein´s notion that language is an activitie followed by rules, wich correction criterion may be external and intersubjective

Metodologia para estudo do volume e densidade absoluta da placenta humana de termo

OBJETIVO: comparar duas metodologias para o cálculo do volume placentário em gestações normais de termo: a do princípio de Arquimedes e a do volume do cilindro, para estimar a densidade absoluta da placenta. Definir a metodologia mais adequada para o cálculo do volume e densidade placentários, que se relacione com o peso e classificação do recém-nascido. MÉTODOS: foram estudadas 50 placentas provenientes de gestações de termo sem complicações e calculados o volume e a densidade absoluta placentários: a) pelo princípio de Arquimedes e b) na suposição de que a placenta seria uma secção de cilindro com duas alturas diferentes do bolo placentário: com a altura média e com a altura da média aritmética do centro e extremidades. As densidades absolutas placentárias foram calculadas pelo quociente entre o peso ao ar da placenta e os diferentes volumes. RESULTADOS: a maioria das gestantes eram multíparas, idade média de 25,4 anos, volume placentário médio entre 547,8 e 610 cm³ e densidade média entre 0,94 e 1,14 g/cm³, dependendo da metodologia empregada. CONCLUSÕES: a metodologia mais adequada para estimar o volume placentário no termo foi a do princípio de Arquimedes, pela melhor correlação com o peso dos recém-nascidos, o índice placentário e a classificação do peso dos recém-nascidos em relação à idade gestacional.

Estudo vídeo-polissonográfico em recém-nascidos de termo pequenos para a idade gestacional

Analisamos o exame video-polissonográfico de 26 recém-nascidos de termo (RNT) com 24 horas de vida. Os RN tinham exame neurológico e ultrassonográfico cerebral normais e apresentaram período perinatal isento de complicações. Foram subdivididos em dois grupos, um controle constituído de 11 RNT com peso adequado para a idade gestacional; e um grupo de 15 RN com peso abaixo do esperado para o termo (RNT-PIG). do segundo grupo, 13 RN apresentaram algum tipo de alteração ao exame video-polissonográfico. As alterações mais frequentes foram na arquitetura do sono, 11 casos, e no comportamento, em que oito RN apresentaram número excessivo de sobressaltos (startle) em relação ao grupo controle e dois RN uma atividade motora reduzida. Os resultados deste estudo demonstram a utilidade da video-polissonografia quando aplicada a RNT-PIG. O exame mostrou-se sensível em detectar diferenças no comportamento, arquitetura do sono e padrão eletrencefalográfico dos RNT-PIG quando comparados ao grupo controle.

Estudo comparativo entre a acepromazina, clorpromazina e levomepromazina em diferentes doses, através do exame bispectral, termo e pressoalgimetria, em cães

The study's objective was to realize comparisons among different acepromazine, chlorpromazine and methotrimeprazine doses, evaluate parametric changes, test analgesia using press and term algimetry, and evaluate bispectral condition. 90 mongrel dogs were used, male and female, adult, weighting 10 to 15 Kg as a rule, distributed in 9 groups with 10 animals each. At first, second and third groups acepromazine was used at 0,1; 0,05 e 0,025 mg/Kg, respectively. At forth, fifth and sixth groups, chlorpromazine was used at 1,0; 0,5 and 0,25 mg/Kg, respectively. At seventh, eighth and ninth groups, methotrimeprazine at 1,0; 0,5 and 0,25 mg/Kg was used, respectively. All drugs were administered intravenously. objects of study: heart rate (HR), non invasive blood pressure (SAP, MAP, DAP), respiratory rate (f), capnography (ETCO(2)), pulse oxymetry (SatO(2)), mouth and rectal temperature, bispectral index (BIS), electromyography (EMG%), press and term algimetry. Somatic analgesia was evaluated by animal's response to nociceptives stimulus. We concluded that chlorpromazine had more bypotension. Dogs showed higher hypnosis level at: chlorpromazine group, with evident myorelaxation. All groups showed analgesia to thermic and mechanic stimulus. Acepromazine group showed high duration to both pain stimuli. Bispectral index was shorten at chlorpromazine group at 1,0 mg/kg doses, showing higher hypnosis index, and acepromazine was the less depressing considering the bispectral index.

Valência do nome deverbal e nominalidade prototípica

O objetivo deste trabalho é mostrar que os nomes deverbais preservam a estrutura argumental do verbo input correspondente e que a especificação ou não dos argumentos no interior do termo nominal depende de um conjunto de fatores pragmáticos, especialmente relacionados a informação de curto termo compartilhada pelos participantes da interação. Como implicação teórica, a análise preserva a idéia de que há um processo gradual de descategorização verbal, que se reflete nos diferentes tipos de marcação gramatical. Conforme o predicado verbal ganha estatuto nominal, as marcações tipicamente oracionais dão lugar a outros mecanismos, como marcação argumental por preposição, modificação por adjetivo, uso de pronomes possessivos, que acompanham apropriadamente um núcleo nominal.

A idéia de império e a fundação da monarquia constitucional no Brasil (Portugal-Brasil, 1772-1824)

Cet article met les conceptions et projets politiques ayant trait au processus conduisant à la constituion impériale brésilienne de 1824 dans un contexte historique dont le pont de départ est la notion d'empire civil, telle qu'elle se développa lors de la réorganisation politico-administrative du royaume et de l'empire du Portugal au XVIIIe siècle. Le texte montre qu'avec le couronnement de Pierre I on fit un usage moderne d'une institution ancienne, le sacre royal, ce qui servit à étayer une sujection politique fondée sur la raison universelle humaine. Cette étude permet de comprendre pourquoi le Brésil indépendant fut pour commencer un empire, pas un royaume, ainsi que le sens profond du pouvoir modérateur attribué à l'empereur par la constitution de 1824.

This article analyzes the degree of thermopluviometric influence on certain indicators in the commerce of Maringa, state of Parana. To the end, climate elements, such as the temperature and prectipitation as well as certain economic indicators, namely: ICMS (taxes), SCPC, Video-Check, Consumption and Consumers of Electric Energy were studied. Graphical analyses along with statistical applications of correlation and regression were performed, as well as the examination of a case study. It is believed that the groups investigated showed variations in the forms of correlation. The results herein presented are in the manner of preliminary trial, representing a first attempt at measuring the actual relationship between the climatic variables (temperature and precipitation) with certain behavioural indicators of commerce in the city of Maringa.

Relação do peso de recém-nascidos e placentas. Estudo em recém-nascidos de termo, pré-termo e pós-termo, de pesos adequado, baixo e grande para a idade gestacional

Birth weight and placental weight of 566 newborns were determined. The newborns were classified by birth weight and gestational age in seven groups: term, preterm and postterm newborns with weight appropriate for gestational age; term and postterm newborns small for gestational age; term and preterm newborns large for gestational age. The differences in the mean placental weight in the preterm, term and postterm newborns with weight appropriate for gestational age were not significant. After 34 weeks of gestation there was little increase in placental weight. The mean placental weight of newborns large for gestational age was significantly different from that of term newborns appropriate for gestational age. In the term and postterm newborns small for gestational age the mean placental weight was significantly different from term and postterm newborns appropriate for gestational age. These findings suggest that newborns with an appropriate intrauterine growth have little increase in placental weight in the gestational period. Gestational age is not an important factor in determining placental weight in this period. Nutrition is important for placental growth-retarded infants have small placentas and large-for-date infants have large placental weight.

O espectro médio de longo termo na pesquisa e na clínica fonoaudiológica.

BACKGROUND: One of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis--although frequently used--, as it is influenced by socioeconomic and cultural aspects as well as individual preferences. Many are the adjectives and methods used in this assessment, especially because of the subjectivity involved in the process, leading to incompatibilities between listeners and difficulties in reaching a consensus on the use of this or that terminology. In such a context, the voice laboratory and more specifically the acoustic computerized analysis, has guided and complemented speech-language treatments. Among the several possibilities of spectrographic analysis, the (Long-Term Average Spectrum--LTAS) quantifies the quality of voices, pointing differences between gender, age, professional--spoken and sang--and dysphonic voices. The LTAS has been used a lot in researches that investigate voice. As it evidences the contribution of the glottic source and of resonance to the quality of voice, it provides objective parameters for the evaluation of this aspect which usually depends on our auditive perception. AIM: to demonstrate how LTAS can be applied in voice research and in the speech-language therapy practice, describing both the technical aspects required for the production and interpretation of results, and its limitations. CONCLUSION: The area of voice research has developed a lot in these last two decades especially because of the advent of the voice and speech laboratory. For this reason, the knowledge about the applicability of more tools for voice analysis, as the LTAS, as well as the existing need for more studies in this area, will most certainly contribute for the creation of new research areas not only in the field of professional voice but also in the field of therapy.
