Poor posture control has been associated with an increased risk of falls and mobility disability among older adults. This study was conducted to assess the test-retest reliability and sensitivity to group differences regarding the time-limit (TLimit) of one-leg standing and selected balance parameters obtained with a force platform in older and young adults. A secondary purpose was to assess the relationship between TLimit and these balance parameters. Twenty-eight healthy older adults (age: 69±5years) and thirty young adults (age: 21±4years) participated in this study. Two one-leg stance tasks were performed: (1) three trials of 30s maximum and (2) one TLimit trial. The following balance parameters were computed: center of pressure area, RMS sway amplitude, and mean velocity and mean frequency in both the anterio-posterior and medio-lateral directions. All balance parameters obtained with the force platform as well as the TLimit variable were sensitive to differences in balance performance between older and young adults. The test-retest reliability of these measures was found to be acceptable (ICC: 0.40-0.85), with better ICC scores observed for mean velocity and mean frequency in the older group. Pearson correlations coefficients (r) between balance parameters and TLimit ranged from -0.16 to -0.54. These results add to the current literature that can be used in the development of measurement tools for evaluating balance in older and young adults. © 2013 Elsevier Ltd.

OBJETIVO: Descrever o desempenho de crianças com Distúrbio Específico de Linguagem (DEL) em provas de leitura, escrita, aritmética, consciência fonológica e memória seqüencial auditiva, assim como, verificar se há associação positiva entre as provas que avaliam a aprendizagem escolar e as que avaliam o processamento da informação. MÉTODOS: Vinte sujeitos com diagnóstico de DEL, com idades entre 7 e 12 anos, foram submetidos ao Teste de Desempenho Escolar (TDE) e a duas provas, que avaliam o processamento da informação (Perfil de Habilidades Fonológicas e Subteste de Memória Seqüencial Auditiva do Teste de Illinois de Habilidades Psicolingüísticas - ITPA). RESULTADOS: A maioria apresentou alteração em todas as provas realizadas. As associações entre o desempenho do grupo nas diferentes provas demonstram que a habilidade metafonológica apresentou associação estatisticamente significante com as habilidades de leitura (p=0,02) e escrita (p=0,02). Por sua vez, a habilidade de memória seqüencial auditiva apresentou associação estatisticamente significante apenas com a habilidade de aritmética (p=0,0003). CONCLUSÃO: O desempenho escolar, assim como as habilidades de consciência fonológica e memória de curto prazo mostraram-se defasados na maioria dos sujeitos avaliados, havendo associação positiva entre: a prova de memória de curto prazo e a prova de aritmética; a prova de consciência fonológica e as provas de leitura e escrita. Neste contexto, reforça-se aqui a utilização de programas de intervenção baseados em Modelos Psicolingüísticos, que sugerem o uso de estratégias individuais para o desenvolvimento das habilidades metafonológicas.

O objetivo neste estudo foi determinar o melhor período de avaliação para medidas de desempenho, consumo e eficiência alimentar. Durante 112 dias, 60 machos da raça Nelore, recém-desmamados, submetidos à prova de ganho de peso, foram alimentados em baias individuais para determinação do consumo alimentar e do desempenho. O peso corporal dos animais foi determinado a cada 28 dias, depois de jejum de 16 horas de líquidos e sólidos. As alterações na variância, variância relativa e correlações de Pearson e Spearman entre os dados dos períodos de avaliação reduzidos (28, 56 e 84 dias) e período total (112 dias) foram usados para determinar a melhor duração do período de avaliação. A duração do período de avaliação para ganho médio diário, consumo de matéria seca, conversão alimentar e consumo alimentar residual pode ser reduzida para 84, 28, 84 e 84 dias, respectivamente, pois tal redução não diminui significativamente a confiabilidade das avaliações em animais alimentados em baias individuais.

Background: The time synchronization is a very important ability for the acquisition and performance of motor skills that generate the need to adapt the actions of body segments to external events of the environment that are changing their position in space. Down Syndrome (DS) individuals may present some deficits to perform tasks with synchronization demand. We aimed to investigate the performance of individuals with DS in a simple Coincident Timing task. Method. 32 individuals were divided into 2 groups: the Down syndrome group (DSG) comprised of 16 individuals with average age of 20 (+/- 5 years old), and a control group (CG) comprised of 16 individuals of the same age. All individuals performed the Simple Timing (ST) task and their performance was measured in milliseconds. The study was conducted in a single phase with the execution of 20 consecutive trials for each participant. Results: There was a significant difference in the intergroup analysis for the accuracy adjustment - Absolute Error (Z = 3.656, p = 0.001); and for the performance consistence - Variable Error (Z = 2.939, p = 0.003). Conclusion: DS individuals have more difficulty in integrating the motor action to an external stimulus and they also present more inconsistence in performance. Both groups presented the same tendency to delay their motor responses. © 2013 Torriani-Pasin et al.; licensee BioMed Central Ltd.

In a supplier of building products were identified difficulties in communication between the Product Development area and other areas of the company that could spoil projects and processes. The process of product development is important in placing the company in the market, and through research and planning, design new products and seek to comply with the costumer in relation to deadlines, quality and cost-effective. The development of a product involves many areas in the company and communication is essential in this process. The goal of this study was to identify possible communication problems permeated by organizational culture and structure of project management working in the company. A survey was applied using a Likert scale in three different areas of the company, with questions including the topics: communication, culture and organizational structure of project management and subsequently conducted the median test and the Spearman test to analysis of responses. With the understanding and analysis of the survey it was confirmed the difficulties of communication between people and the areas of the company, besides there is an influence of the type of culture acting in the company and the current management structure of the project in a good performance of internal communication

The objective of the present study was to evaluate the characteristics of the sward canopy of Marandu grass during the rainy season, the wet-to-dry transition and the dry seasons, between March and September 2004, under intermittent grazing, and to correlate those characteristics with the performance of crossbred heifers receiving mineral supplements ad libitum or protein supplements. The experiment consisted of a randomized block design with three blocks (set of 13 paddocks), each containing five crossbred heifers per experimental unit, totaling 15 replicates. The heifers were given protein supplements daily in individual stalls and received an average 4 g/kg/day of the supplement during the rainy season and 5 g/kg/day during the dry season. Their weight gain was assessed monthly. The pasture structure was assessed through destructive sampling, and the bromatological composition of esophageal extrusa samples was also assessed. Analysis of variance was used to assess performance, and regression analysis was used to evaluate the sward canopy characteristics in relation to the months of the year. A cluster procedure was used to determine the similarity between the months of the year under assessment. Two different groups were formed for pasture evaluation: one group including the months of March to July and another group including the months of August and September. The first group exhibited a better canopy structure than the second group. This fact was corroborated by the animal performance, which was lower during the months of the second group. Low-intake protein supplementation was effective in increasing the performance of the grazing heifers. Pasture structure is critical for animal performance in a grazing environment, regardless of the type of supplementation.

PURPOSE: To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students.METHODS: Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of instructors, while group B (control) received a faculty-directed training based on books and instructional videos. All students underwent a both pre-and post-tests to perform two-and three-dimensional sutures on ox tongue. All recorded performances were evaluated by two blinded evaluators, using the Global Rating Scale.RESULTS: Although both groups have had a better performance (p<0.05) in the post-test when compared with the pre-test, the analysis of post-test showed that group A (EVA) had a better performance (p<0.05) when compared with group B (control).CONCLUSION: The ethylene vinyl acetate bench model allowed the novice students to acquire suture skills faster when compared to the traditional model of teaching.
