Competitive artistic gymnastics and coaches' philosophy

The current study is a piece from the original project entitled "Diagnosis of the Artistic Gymnastics Development Program in Brazil". Among others issues, the coaching philosophy of coaches who are developing gymnasts that may be representative of the national team was a matter of analysis. We interviewed 46 coaches from 29 sports institutions in Brazil. As data collection we used a semi-structured interview and for data treatment we adopted the content analysis method of Bardin (2010). We have found out that there is an inconsistent philosophical basis, and in many institutions this has been mixed up with the objectives of the training program or just doesn't exist. This fact needs consideration and criticism, but we know that the coaching philosophy is not developed during the coaching education courses.

Nursing care practices at an outpatient care center from an integrative perspective

Aim: to analyze nursing care practices at a Specialized Outpatient Care Center from the perspective of an integrative health care activity. Method: Interviews with 24 nursing professionals were undertaken. For data analysis, Thematic Content Analysis as proposed by Bardin was applied, resulting in the following themes: the team size and its commitment to health care; professional practices and activity of the nursing team. Results: The size of the nursing team was considered insufficient, which compromises the quality of care and results in work overload and dissatisfaction of the nursing professionals. On the other hand, they were satisfied with the tasks performed day-to-day and related integrality to individual care, considered it essential and usually practiced it daily. Conclusion: It is considered that the nursing team has the potential and commitment to develop their care practice combined with the integrative perspective, and therefore providing quality health care to the population.

O brinquedo terapêutico e o preparo da criança para cirurgia de correção de fissura labiopalatina

Objectives: to use the toy as a therapeutic resource in the preparation of children undergoing surgical repair of cleft lip and palate preoperatively; to describe quali-quantitativelly the behavioral reactions of the child during the two periods, pre-and postoperatively. Method: quali-quantitative study, developed in a specialized hospital, with 40 children aged between 7 and 12 years old who underwent surgery for correction of cleft lip and palate. Data collection was by means of an instrument with 21 behavioral variables preoperatively and postoperatively. Content analysis was used in the speech of mothers and children. This study was the research project approved by the Ethics Committee, CAAE No. 050/2011. Results: the variable is a presented questioner p> 0.0265 and four categories emerged after content analysis. Conclusion: therapeutic toy is a feature that makes children relieve stress, and facilitates the implementation of nursing care.

Numeric reconstruction of cytoskeleton with finite element method and topology optimization method

The importance of mechanical aspects related to cell activity and its environment is becoming more evident due to their influence in stem cell differentiation and in the development of diseases such as atherosclerosis. The mechanical tension homeostasis is related to normal tissue behavior and its lack may be related to the formation of cancer, which shows a higher mechanical tension. Due to the complexity of cellular activity, the application of simplified models may elucidate which factors are really essential and which have a marginal effect. The development of a systematic method to reconstruct the elements involved in the perception of mechanical aspects by the cell may accelerate substantially the validation of these models. This work proposes the development of a routine capable of reconstructing the topology of focal adhesions and the actomyosin portion of the cytoskeleton from the displacement field generated by the cell on a flexible substrate. Another way to think of this problem is to develop an algorithm to reconstruct the forces applied by the cell from the measurements of the substrate displacement, which would be characterized as an inverse problem. For these kind of problems, the Topology Optimization Method (TOM) is suitable to find a solution. TOM is consisted of an iterative application of an optimization method and an analysis method to obtain an optimal distribution of material in a fixed domain. One way to experimentally obtain the substrate displacement is through Traction Force Microscopy (TFM), which also provides the forces applied by the cell. Along with systematically generating the distributions of focal adhesion and actin-myosin for the validation of simplified models, the algorithm also represents a complementary and more phenomenological approach to TFM. As a first approximation, actin fibers and flexible substrate are represented through two-dimensional linear Finite Element Method. Actin contraction is modeled as an initial stress of the FEM elements. Focal adhesions connecting actin and substrate are represented by springs. The algorithm was applied to data obtained from experiments regarding cytoskeletal prestress and micropatterning, comparing the numerical results to the experimental ones

Combining fractal and deterministic walkers for texture analysis and classification

In this paper,we present a novel texture analysis method based on deterministic partially self-avoiding walks and fractal dimension theory. After finding the attractors of the image (set of pixels) using deterministic partially self-avoiding walks, they are dilated in direction to the whole image by adding pixels according to their relevance. The relevance of each pixel is calculated as the shortest path between the pixel and the pixels that belongs to the attractors. The proposed texture analysis method is demonstrated to outperform popular and state-of-the-art methods (e.g. Fourier descriptors, occurrence matrix, Gabor filter and local binary patterns) as well as deterministic tourist walk method and recent fractal methods using well-known texture image datasets.
