Flexibilidade anterior do tronco no adolecente após o pico da velocidade de crescimento em estatura

Flexibilidade anterior do tronco (FAT) é um componente importante dos exames clínico e de aptidão física utilizado como indicador da função vertebral. O teste mais utilizado para sua quantificação é o sentar-e-alcançar (TSA), que considerara como padrão de normalidade o toque das mãos nos pés, com critérios e parâmetros de análise que independem das variáveis. Neste estudo, investigou-se a FAT em adolescentes, após o pico da velocidade de crescimento em estatura, em função do sexo, da velocidade de execução e dos dados antropométricos. Os índices foram obtidos em centímetros; o peso corporal em kg. Participaram 102 adolescentes, sendo 45 mulheres e 57 homens, entre 16 e 20 anos de idade. Resultados indicam que o fator sexo, dados antropométricos e a velocidade de execução do teste influenciam os índices de flexibilidade; a avaliação da função vertebral não pode ter como critério de normalidade atingir os pés pelo TSA, e que a velocidade rápida leva a melhores resultados. em resumo, os resultados indicam que tocar os pés, é um critério que exclui da normalidade da função vertebral aproximadamente 50% dos adolescentes. Assim, o critério para tomada de decisão quanto ao encaminhamento do adolescente para recuperação de maiores índices de flexibilidade precisa ser revisto.

Selection of environmental temperature by the yellow scorpion Tityus serrulatus Lutz & Mello, 1922 (Scorpiones, Buthidae)

The preferred temperature of the yellow scorpion Tityus serrulatus was investigated since its dispersion is a matter of concern. Adult T. serrulatus, weighing 1.24 ± 0.20 g (mean + sd) and with a standard length of 59.3 ± 2.5 mm, were used. A metallic corridor (120 cm long, 5 cm large and 10 cm high) with thermal gradient ranging from 0°C to 40°C was used. Tityus serrulatus chose and stayed in temperatures ranging from 14° C to 38°C when safe conditions were offered (dark and thigmotactic stimuli). The number of animals that remained in the 11°C-20°C, 21°C-30°C, and 31°C-40°C temperature zones were 8, 8, and 9, respectively. The chi-square test (degree of freedom = 2) showed that differences were not significant (p>0.05). Some animals moved to lower temperature areas (less than 8°C) when the corridor was completely illuminated and thigmotactic stimuli were absent, which led the animals to present a torpor state. It is concluded that T. serrulatus does not select a specific environmental temperature. Associated with the capacity of temporally surviving at low temperatures, this species seems to be highly adaptable to different thermal zones.

A development process proposal for the ERP5 system

Modeling ERP software means capturing the information necessary for supporting enterprise management. This modeling process goes down through different abstraction layers, from enterprise modeling to code generation. Thus ERP is the kind of system where enterprise engineering undoubtedly has, or should have, a strong influence. For the case of Free/Open Source ERP, the lack of proper modeling methods and tools can jeopardize the advantage brought by source code availability. Therefore, the aim of this paper is to present a development process proposal for the Open Source ERP5 system. The proposed development process aims to cover different abstraction levels, taking into account well established standards and common practices, as well as platform issues. Its main goal is to provide an adaptable meta-process to ERP5 adopters. © 2006 IEEE.

Relação entre percepção e ação durante os movimentos de sentar e levantar em indivíduos idosos

The purpose of this study was to analyze aging effects on the perceptual and motor aspects involved in the sit-to-stand and stand-to-sit actions. Young and older individuals were videotaped while performing those actions on a chair adjusted with seven seat heights. Participants estimated, for each seat height, the difficulty/facility perceived while performing the sit-to-stand and stand-to-sit actions. Older individuals exhibited changes in the control strategy used for sitting at the lowest seat height, and overestimated the degree of difficulty/facility involved in performing both actions. In general, the degree of easiness perceived by older individuals at the lowest seat height disagrees with the degree of difficulty exhibited during the motor performance of this task.

Automatic segmentation of digital images applied in cardiac medical images

The digital image processing has been applied in several areas, especially where it is necessary use tools for feature extraction and to get patterns of the studied images. In an initial stage, the segmentation is used to separate the image in parts that represents a interest object, that may be used in a specific study. There are several methods that intends to perform such task, but is difficult to find a method that can easily adapt to different type of images, that often are very complex or specific. To resolve this problem, this project aims to presents a adaptable segmentation method, that can be applied to different type of images, providing an better segmentation. The proposed method is based in a model of automatic multilevel thresholding and considers techniques of group histogram quantization, analysis of the histogram slope percentage and calculation of maximum entropy to define the threshold. The technique was applied to segment the cell core and potential rejection of tissue in myocardial images of biopsies from cardiac transplant. The results are significant in comparison with those provided by one of the best known segmentation methods available in the literature. © 2010 IEEE.

Reprodutibilidade de medidas antropométricas estáticas de graduandos de odontologia e de mochos odontológicos

Objective: To evaluate the intraexaminer reproducibility of static anthropometric measurements of undergraduate dental students as well as the characteristics and regulating measurements of the dental stools used by them. Methods: Forty volunteers and 6 types of dental stools were evaluated. For the anthropometric measurements the employed equipments were: an adapted office chair, aflexible measuring tape with two adapted rods, a metallic device with a 90 degree central angle, string, a 35 x 24 cm rectangular wooden board, isolating tape and crepe tape. In order to standardize the position of the adapted office chair and the volunteers' feet, the floor was marked with the isolating and crepe tapes. A string was attached to the waist of each volunteer to mark the area corresponding to the kidney region making it possible to measure the seat-renal region area. The examined anthropometric measurements were height, trunkcephalic heigh, sacral-popliteal distance (OK?), hip width, popliteal height and the seat-renal region height. The evaluated characteristics of the dental stools relative to the seat were depth, horizontal width and minimum/maximum height. The back of the dental stool was evaluated as for the minimum/ maximum height adjustment. The anthropometric and dental stool measurements were obtained by a single examiner at two moments with a 1-week interval between the evaluations. Intra-class correlation coefficient (ρ) was used to estimate the intraexaminer reproducibility. Results: Excellent reproducibility was observed for all anthropometric measurements obtained (ρ=0.99) as well as for all dental stools evaluated (ρ=0.99). Conclusion: The method used to obtain the anthropometric and dental stools measurements was reproducible and can be used reliably.

Treinamento esfncteriano anal: Estudo transversal em crianças de 3 a 6 anos de idade

Objective: To assess the practice of children's toilet training through interviews with parents and caretakers. Methods: A cross-sectional study of healthy children using a questionnaire applied to parents or caretakers of 100 consecutive children aged 3 to 6 years old. Results: 97% of the children were home-trained by their mothers and 92% of them used their intuition, previous experience with an older child and grandmothers' experience. Bowel and bladder toilet training started simultaneously in 84% of the cases, whereas 41% of the children mastered stool control earlier. Mothers with lower educational level and of social classes C, D and E initiated the training earlier and one of the related reasons was the cost of disposable diapers. Age in initiation or duration of toilet training was similar for boys and girls. Children presented most of the readiness symptoms for toilet training and only a small number of them used a seat reducer or a foot support. There was no increase in constipation prevalence after toilet training and there was no encopresis. Conclusions: Mothers were responsible for bowel toilet training and initiated it with no specialized help. In C-D-E social classes, the cost of diapers was determinant to initiate bowel toilet training.
