Estudo de caso sobre os mecanismos de defesa contra a inflação utilizados por uma empresa nacional em situação de forte ritmo de ascensão de preços

A situação de alta inflação vigente na economia brasileira desde meados da década de oitenta, força as organizações empresariais a encontrar mecanismos que alimentem seu sistema de informaç5es e possibilitem o cumprimento de contratos e o processo de tomada de decisões. Utilizando a técnica do estudo de caso, este trabalho acompanha a experiência de uma organização empresarial em seu processo de adaptação à realidade econômica, após diagnosticar que o seu sistema de informações apresentava um nível muito reduzido de eficácia, ao não incorporar dados sobre as variações de preços na economia. O uso da indexação de valores monetários acompanhado de medidas de reorganização administrativa, da incorporação de novos controles econômicos e financeiros e da expansão da automatização levaram a empresa a um novo estágio de gestão

A relação ritmo-movimento no fazer musical criativo : uma abordagem construtivista na prática de canto coral

A presente pesquisa investiga a relação do movimento corporal na construção do conceito de ritmo a partir de um trabalho de composição coletiva, abrangendo os seguintes momentos: a) Composição rítmico-corporal; b) Representação gráfica; c) Entrevista individual; c) O aprendizado em grupo: a construção da performance. Este trabalho foi desenvolvido em uma situação de canto coral, contando com a participação de 30 meninas entre 11 e 18 anos. Integrar o movimento corporal compreende uma proposta de canto coral construtivista, tomando por base a trilogia cognição-música-corpo. A partir dessa inter-relação, muitos autores de diferentes áreas fazem-se presentes, porém buscamos um aprofundamento na teoria construtivista interacionista de Jean Piaget, mais especificamente no seu conceito de tomada de consciência, a fim de analisar o processo de construção rítmica de nossas alunas-cantoras. A metodologia empregou o Método Dialético-Didático, uma extensão do Método Clínico, na observação e intervenção com os grupos e nas entrevistas individuais. Os resultados mostraram que o envolvimento do movimento corporal favorece a compreensão da estruturação rítmica, desencadeando tomadas de consciência a partir da observação de si mesmo, pois é o próprio corpo em movimento que desenha os tempos no espaço. Além disso, sentir o próprio corpo nesse processo tem favorecido a performance de modo geral, contribuindo com a afinação, a descontração e a expressividade do grupo.

Funcionalidade em pacientes após acidente vascular encefálico: relação com o sono e ritmo de atividade-repouso

It is known that sleep plays an important role in the process of motor learning. Recent studies have shown that the presence of sleep between training a motor task and retention test promotes a learning task so than the presence of only awake between training and testing. These findings also have been reported in stroke patients, however, there are few studies that investigate the results of this relationship on the functionality itself in this population. The objective of this study was to evaluate the relationship between functionality and sleep in patients in the chronic stage of stroke. A cross-sectional observational study was conducted. The sample was composed of 30 stroke individuals in chronic phase, between 6 and 60 months after injury and aged between 55 and 75 years. The volunteers were initially evaluated for clinical data of disease and personal history, severity of stroke, through the National Institute of Health Stroke Scale, and mental status, the Mini-Mental State Examination. Sleep assessment tools were Pittsburgh Sleep Quality Index, the Questionnaire of Horne and Ostberg, Epworth Sleepiness Scale, the Berlin questionnaire and actigraphy, which measures were: real time of sleep, waking after sleep onset, percentage of waking after sleep onset, sleep efficiency, sleep latency, sleep fragmentation index, mean activity score. Other actigraphy measures were intraday variability, stability interdiária, a 5-hour period with minimum level of activity (L5) and 10-hour period with maximum activity (M10), obtained to evaluate the activity-rest rhythm. The Functional Independence Measure (FIM) and the Berg Balance Scale (BBS) were the instruments used to evaluate the functional status of participants. The Spearman correlation coefficient and comparison tests (Student's t and Mann-Whitney) were used to analyze the relationship of sleep assessment tools and rest-activity rhythm to measures of functional assessment. The SPSS 16.0 was used for analysis, adopting a significance level of 5%. The main results observed were a negative correlation between sleepiness and balance and a negative correlation between the level of activity (M10) and sleep fragmentation. No measurement of sleep or rhythm was associated with functional independence measure. These findings suggest that there may be an association between sleepiness and xii balance in patients in the chronic stage of stroke, and that obtaining a higher level of activity may be associated with a better sleep pattern and rhythm more stable and less fragmented. Future studies should evaluate the cause-effect relationship between these parameters

Versão breve da social rhythm metric: um instrumento para avaliar ritmo social de pacientes com acidente vascular cerebral

Stroke is a neurological disorder caused by restriction of blood flow to the brain, which generates directly a deficit of functionality that affects the quality of life of patients. The aim of this study was to establish a short version of the Social Rhythm Scale (SRM), to assess the social rhythm of stroke patients. The sample consisted of 84 patients, of both sexes, with injury time exceeding 6 months. For seven days, patients recorded the time held 17 activities of SRM. Data analysis was performed using a principal components factor analysis with varimax rotation of the full version of SRM in order to determine which activities could compose brief versions of SRM. We then carried out a comparison of hits, the ALI (Level Activity Index) and SRM, between versions, by Kruskal-Walls and the Mann-Whitney test. The Spearman correlation test was used to evaluate the correlation between the score of the full version of SRM with short versions. It was found that the activities of SRM were distributed in three versions: the first and second with 6 activities and third with 3 activities. Regarding hits, it was found that they ranged from 4.9 to 5.8 on the first version; 2.3 to 3.8 in version 2 and 2.8 to 6.2 in version 3, the first the only version that did not show low values. The analysis of ALI, in version 1, the median was 29, in version 2 was 14 and in version 3 was 18. Significant difference in the values of ALI between versions 1 and 2, between 2 and 3 and between versions 1 and 3. The highest median was found in the first version, formed by activities: out of bed, first contact, drink coffee, watch TV in the evening and go to bed. The lowest median was observed in the second version and this was not what had fewer activities, but which had social activities. The medians of the SRM version 1 was 6, version 2 was 4 and version 3 was 6. Significant difference in the values of SRM between versions 1 and 2 and between 2 and 3, but no significant difference between versions 1 and 3. Through analysis, we found a significant correlation only between the full version and the version 1 (R2 = 0.61) (p <0.05), no correlation was found with version 2 (R2 = 0.007) nor with version 3 (R2 = 0.002), this was finally a factor to consider version 1 as the short brazilian version of the Social Rhythm Metric for stroke patients

Avaliação comportamental e neuroquímica de ratos em dessincronização forçada: possíveis implicações para um modelo animal de oscilações no humor

Bipolar disorder has been growing in several countries. It is a disease with high mortality and has been responsible by the social isolation of the patients. Bipolar patients have alterations in circadian timing system, showing a phase shift in various physiological variables. There are several arguments demonstrating alterations in circadian rhythms may be part of the bipolar disorder pathophysiology. Given the necessity for further elucidation, the goal of this study was to validate the forced desynchronization protocol as an animal model for bipolar disorder. To do this, Wistar rats were submitted to a forced desynchronization protocol which consists in a symmetrical light dark cycle with 22h. Under this protocol, rats dissociate the locomotor activity rhythm into two components: one synchronized to the light / dark cycle with 22h, and another component with period longer than 24 hours following the animal endogenous period. These rhythms with different periods sometimes there is coincidence, which we named CAP (Coincidence Active Phase) and the opposite phase, non-coincidence, called NCAP (Non-Concidence Active Phase). The hypothesis is that in CAP animals present a mania-like behavior and animals in NCAP depressive-like behavior. We found some evidence described in detail throughout this thesis. In sum, the animals under forced desynchronization protocol were more stressed, showed an increase in stereotypic behaviors such as grooming and reduction in other behaviors such as risk assessment and vertical exploration when compared to the control group. The CAP animals showed increased locomotor activity, especially during the dark phase when compared to controls (rats under T24) and less depressive behavior in the forced swim test. The animals in NCAP showed a higher anxiety in elevated plus maze, but they don t have ahnedonia. The animals under dissociation have more labeled 5HT1A cells at the amygdala area, which appoint that they have more amygdala inhibition. Taking these data together, we could partially validated the forced desynchronization protocol as an animal model for mood oscillations

Caracaterização do núcleo pré-geniculado do sagüi (Callithrix jacchus) :projeção retiniana, neuroquímica e atividade celular (expressão de FOS)

In rodents, the suprachiasmatic nucleus (SCN) and the intergeniculate leaflet (IGL) are the main components of the circadian system. The SCN is considerate the site of an endogenous biological clock because can to generate rhythm and to synchronize to the environmental cues (zeitgebers) and IGL has been related as one of the main areas that modulate the action of SCN. Both receive projections of ganglion cells of retina and this projection to SCN is called retinohypothalamic tract (RHT). Moreover, the IGL is connected with SCN through of geniculohypothalamic tract (GHT). In primates (include humans) was not still demonstrated the presence of a homologous structure to the IGL. It is believed that the pregeniculate nucleus (PGN) can be the answer, but nothing it was still proven. Trying to answer that question, the objective of our study is to do a comparative analysis among PGN and IGL through of techniques immunohystochemicals, neural tracers and FOS expression after dark pulses. For this, we used as experimental model a primate of the new world, the common marmoset (Callithrix jacchus). Ours results may contribute to the elucidation of this lacuna in the circadian system once that the IGL is responsible for the transmission of nonphotic information to SCN and participate in the integration between photic and nonphotic stimulus to adjust the function of the SCN. In this way to find a same structure in primates represent an important achieve in the understanding of the biological rhythms in those animals

Ritmo de atividade de forrageio de Dinoponera quadríceps em ambiente natural

In order to characterize the seasonal and daily rhythm of Dinoponera quadriceps foraging activity in natural environment, four colonies of D. quadriceps were observed in an area of secondary Atlantic forest in northeastern Brazil. Data collection was performed during 72 hours every three months during an annual cycle. Colonies of D. quadriceps exhibited seasonal variation in foraging activity, peaking in the early dry season, followed by a sudden decline at the end of this season and increasing again at the late rainy season. The seasonal rhythm of foraging was positively related to the duration of the daylight and luminosity, and negatively to the time of sunrise and rainfall. Regarding the daily rhythm, foraging activity was predominantly diurnal independent of season. At the early dry season, the colonies had two activity peaks, one in the morning and another in the afternoon, with a decrease in foraging at midday, while in the rest of the year foraging activity was distributed more evenly throughout the daylight. The daily rhythm of foraging activity had a stronger and positive relation with light intensity. The second most important factor determining the daily rhythm of foraging was temperature that was also positively related for most of the year. Relative humidity showed a weak and negative relation with the daily rhythm of foraging in just one month of observation

Avaliação comparativa do ritmo de piscar em crianças normais em idade pré-escolar

OBJETIVO: Estabelecer o padrão de normalidade do ritmo de piscar em crianças normais em idade pré-escolar. MÉTODOS: Avaliaram-se 200 crianças de 4 a 6 anos, saudáveis, usando tomada de imagens digitais, nos planos frontal e lateral, em estado de vigília, em posição primária do olhar, estando o objeto de observação localizado na altura da pupila. Para a tomada das imagens foi utilizada uma filmadora Sony Lithium, sendo as mesmas gravadas em fitas 8 mm, transferidas para um computador MacIntosh G4 e processadas pelo programa iMovie, estudando-se: o tempo de abertura e o tempo de fechamento palpebral, o tempo de piscar completo e o ritmo de movimentos palpebrais por minuto, durante 3 minutos. Os resultados foram avaliados por estatística descritiva e gráfico de linhas. RESULTADOS: O piscar completo foi mais freqüente que o incompleto. O ritmo do piscar completo aumenta com o aumento da idade. Para o piscar incompleto, os valores foram semelhantes em todas as idades avaliadas. O tempo de fechamento e de abertura palpebral e o tempo de piscar completo foram semelhantes em meninos e meninas. O tempo de fechamento foi mais lento que o tempo de abertura palpebral. CONCLUSÕES: O ritmo de piscar completo aumenta com a idade. Os tempos de fechamento e de abertura palpebral e o tempo de piscar completo foram semelhantes em ambos os sexos, em todas as idades estudadas, sendo o fechamento mais lento que a abertura palpebral.
