title: PERCEPTIONS AND BENEFITS OF STATIC AND DYNAMIC STRETCHING IN DANCERS: QUALITATIVE AND QUANTITATIVE ASPECTS

description: ABSTRACT The present study investigated the beneficial effects induced on dancers by the two types of stretching protocol: static and dynamic stretching, in order to elevate the aesthetics of the figures and body positions to the highest level. The subjects were 20 young female dancers divided into two groups: Group DS (n=10), which performed dynamic stretching, and Group SS (n=10), a static stretching, both for six months. A survey, with the aim of assessing perceptions about the benefits induced by the type of stretching performed, and a Sit and Reach Test were administered to the dancers to assess both qualitative and quantitative aspects of flexibility. An independent samples t-test was performed to assess the differences in flexibility between DS and SS group before and after six months, and a Fisher's exact test to analyse their perceptions on the benefits induced by two training protocols. Result was statistically significant after six months and four associations were found (P &lt;0.05). Dynamic stretching brought greater benefits both qualitatively and quantitatively. From the results of the study, it was possible to state that dancers in terms of induced benefits and satisfaction with the performance result achieved, preferred dynamic stretching.

title: Diagnosis of frontotemporal dementia: recommendations of the Scientific Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology

description: ABSTRACT “Frontotemporal dementia” (FTD) is a clinical syndrome characterized by the focal involvement of the frontal and/or temporal lobes. FTD has three clinical phenotypes: the behavioral variant and two linguistic subtypes, namely, non-fluent/agrammatic primary progressive aphasia (PPA-NF/A) and semantic PPA (PPA-S). FTD is the second most common cause of dementia in individuals under the age of 65 years. This article presents recommendations for the diagnosis of FTD in the Brazilian scenario, considering the three levels of complexity of the health system: primary health care, secondary and tertiary levels. Diagnostic guidelines are proposed, including cognitive testing, behavioral and language assessments, laboratory tests, and neuroimaging.

title: A REVIEW ON THE STUDY OF MAINTENANCE EFFECTIVENESS

description: ABSTRACT Increasing human dependence on engineering systems has recently made maintenance a higher priority. Thus, it becomes essential to study the many developments in this field, paying attention to some proposed models that do not appear to be effective in real applications. In this paper, we present a literature review on “maintenance effectiveness”, here defined as the level to which a maintenance policy fulfills its pre-defined objectives or optimizes general maintenance actions, hence improving the productive activities of an organization. Some insights into the research so far developed - such as the relationship between interest in studying maintenance effectiveness in a sector and the severity of catastrophic failures in that sector - and possible future trends - such as the focus on case studies rather than more theoretical papers - are presented. We also found that there are still gaps in the literature that, if explored, will open new routes in potentially promising directions.

title: A COMPARISON OF THE PERFORMANCE OF THE GEOMETRIC PROCESS AND ITS EXTENSIONS

description: ABSTRACT The geometric process (GP) is a stochastic process that was an extension of the renewal process. It was introduced by Lam (1988) in 1988 with an intention to model the failure process of a repairable system whose the times between failures become shorter and shorter after repairs and repair times become longer and longer. The GP has been widely studied in the literature of reliability and maintenance and applied in optimisation of maintenance policies. Some authors have proposed various versions of its extensions (or the GP-like models), including the α-series process, the threshold GP, the extended Poisson process, the doubly GP, and the doubly-ratio GP. Some papers also compare the performance of the GP with that of other models, but not with the performance of the extensions of the GP. This paper therefore reviews the GP-like models, compares the performance of the GP and its extensions in terms of the Akaike information criterion (AIC), the corrected AIC (AICc) and the maximum likelihood (ML) based on 25 real-world datasets. Besides, the least square methods for estimating the parameters in some models are discussed, which is used for model performance of GP and GP-like models. The finding is useful for practitioners in their selection of the GP-like models.

title: THE KNOWLEDGE OF THE SPORTS COACH IN THE CONTEXT OF SOCIAL PROJECTS

description: ABSTRACT Brazil has numerous social projects that aim to guarantee the right to sport for those who live in situations of social vulnerability. The aim of this article was to identify knowledge for professional practice in social projects, based on the perceptions of the coaches themselves. Interviews were conducted with six coaches from the largest Brazilian social program, Second Half Program (Progama Segundo Tempo). Getting to know the sport being worked on and its students were the most expressive results. Still, knowing pedagogical and contextual issues are presented as necessary. We understand this study as an important step towards promoting contextualized discussions about these coaches, who live with risky situations and have a significant social and training role in our society.

title: Trees of the cerrado in the Clube Caça e Pesca Itororó, Uberlândia, Minas Gerais State, Brazil

description: ABSTRACT We present a floristic survey of the trees in the stricto sensu cerrado remnant. In total, 63 species belonging to 46 genera of 26 families were registered. The most represented were Fabaceae (16 spp.) and Vochysiaceae (six spp.) Bowdichia virgilioides Kunth was considered near threatened, e Caryocar brasiliense Cambess. is protected by a state law. Of the registered trees, 19% are endemic to the biome (12 spp.). We present a list of species, identification key and an assessment of the conservation status and endemism of the species found. Due to its “cerrado” representative florist composition, and in order to ensure the conservation of this important genetic heritage, this cerrado remnant should urgently became a protected area again.

title: CT scan in the evaluation of pediatric abdominal trauma

description: ABSTRACT Objective: to assess the need of computed tomography (CT) for the definition of management in pediatric abdominal trauma. Methods: observational retrospective study with patients under 18 years old victims of blunt or penetrating abdominal trauma that underwent CT of the abdomen and pelvis at admission. We evaluated CT scan findings, indications and management. We calculated the sensitivity, specificity, positive predictive value and negative predictive value of clinical variables and energy of trauma for findings on CT. Results: among the 236 patients included in our study, 72% (n=170) did not present abnormal findings on CT. It was performed surgical treatment in 15% (n=10), conservative treatment in 54,5% (n=36) and 27% (n=18) did not receive treatment for abdominal injuries. In the assessment of CT indications, 28,8% (n=68) presented no justifications. In this group, 91% (n=62) did not show any abnormal findings. Among the six patients with positive findings, half were selected for conservative treatment, while the rest did not need any treatment for abdominal injuries. The presence of abdominal pain, hemodynamic alterations and high energy blunt trauma had low positive predictive values when isolated, whereas the negative predictive values were higher. Conclusion: although CT is necessary in some instances, there is a possible high number of exams that did not make any difference in the management of the pediatric population.

title: A DIAGNOSTICS AND PROGNOSTICS FRAMEWORK FOR MULTI-COMPONENT SYSTEMS WITH WEAR INTERACTIONS: APPLICATION TO A GEARBOX-PLATFORM

description: ABSTRACT We present a novel framework for diagnostics and prognostics for multi-component systems with wear interaction between components. The principal elements of this framework are: health-state indicator extraction using signal-processing; clustering of wear phases using a Gaussian mixture model; a stochastic multivariate wear model; and prediction of the remaining-useful-life of components using particle-filtering. These elements of the framework are illustrated and verified using an experimental platform that generates real data. Our diagnostics study shows that different clusters not only indicate the wear-state, but also the wear-rate of the components. Furthermore, our prognostics study shows that the wear-interaction between components has an significant impact in predicting the remaining-useful-life for components. Thus, we demonstrate, for prognostics and health management, the importance of modeling wear interactions in the prognostic process of multi-component systems.

title: Paying for crime: frauds in DPVAT insurance and their impacts on society

description: Abstract The goal of this paper is to assess the weight of fraudulent claim payments of DPVAT insurance by the insurer Líder, a consortium of private insurers who manage this product. Using the Actuarial Credibility Theory, and a official database, the discrepancy between the DPVAT claims ratio and the claims ratios of other private automobile insurance lines of business, proxies for the ideal premium formation for having better system of frauds detection and prevention. The results indicate significant differences among the values. Additionally, in two counterfactual scenarios, it was estimated: (i) what would be the value of the DPVAT premium in case the fraud effects were purged, aiming to analyze whether the verified heterogeneity could be explained by the volume of proven frauds; (ii) the financial volume that could potentially be saved by society in case the frauds were subtracted since 2006. It is possible to affirm that not only would the DPVAT’s claims ratio be reduced, but also the premiums paid by the insured. Finally, the estimates suggest that society could have saved over BRL 15 billion in 14 years.

title: Between Make-Believe and Make-Belief: children and their performances in recreational play installations

description: ABSTRACT Between Make-Believe and Make-Belief: children and their performances in recreational play installations – Based on Early Childhood Social Studies and Performanc e Studies, this article aims to analyze the ways children in Early Childhood Education, aged 3 to 5 years, produce performances during play in recreational play installations, as the result of research with children. The methodol ogy is based on the Mosaic Approach and on the proposition of recreational play installations. Through the analyses, two units were defined: a) make-believe performances; b) make-belief performances. Thus, it was possible to make inferences about the free movement of children between make-believe and make-belief performances through their body modulations, gestures and voices.

title: EFFECTS OF TWO PHYSICAL EDUCATION PROGRAMS ON CHILDREN'S HEALTH-RELATED PHYSICAL FITNESS ACCORDING TO SEX

description: ABSTRACT This quasi-experimental study evaluated the effects of two physical exercise programs offered in the context of physical education classes on physical fitness indicators. The convenience sample consisted of 91 students aged 9-12 years who formed the group's Body Training (GBT; 45 students) and Physical Education (PE; 45 students). Body mass index (BMI), cardiorespiratory fitness (CRF), flexibility, and abdominal muscle strength (LMS) were measured. The “Paired t-test” and repeated measures ANOVA were used. The size of the effect was estimated by the “partial squared eta”, stratified by sex, with a 5% probability of an error being accepted. The results showed in boys a very high effect in the PFC group on CRF, flexibility, and FML and a high effect in the PEF group on flexibility and FML. In girls, a very high effect in the GBT group on CRF, flexibility, and FML, and the PE group greatly affected flexibility and FML and had a high effect on CRF. There was no effect on BMI in either group. We emphasize that this single weekly meeting (15 minutes of GBT) was able to have a very high and high effect on fitness in favor of the GBT in both genders.
