A influência da mídia na procura por exercícios físicos e suas possíveis consequências psicológicas

Modern society is characterized by the advance of technologies, the emergence and constant development of the technological field is responsible for a series of population adjustments, that being practically molded and daily transformed by media, which usually has the power of manipulating opinions and public approaches in every capacity and extensions of our lives, being a significantly and important tool, which most part of individuals in contemporary society can't work and live without, therefore most part of individuals depend on the use of many technological means, including social means, which have great relationship with the development and emergence of many psychological problems that completely impact on the social life of affected individuals, thus Physical Education is an area with the goal of verifying the level of influence that media reflects on the lifestyle choice to be followed and the relation of this influence with the presence and development of a series of psychological disorders that affect directly the health of those individuals. It has been gathered data about the subject according to scientific basis, more specifically, on Academic Google, Scielo and Pubmed, where it has been researched scientific articles that could contribute with the data and information to complete the text. The psychology of sports is an area of studies and knowledge that investigates and develops insight about these questions, making available scientifically tested and proven materials that supports the P.E. professional, that is connected in the practical field to visualize possible chained symptoms of these psychopathologies according to the development of these psychic disorders, that are usually common in current days, more precisely, disorders such as Anorexia, Vigorexia, self-dependence to physical exercise and selfcorporal dissapproval. It's vital to have total attention with the possibility of evolution of this psychopatology...

Cine física: estudo de vídeos e filmes e possibilidades para o ensino de física na educação básica

In this work we present a didactic proposal of the use of movies and videos for the Physics teaching directed to the Basic Education and we bring a discussion about how the materials addresses this topic. For this, we selected three cinematographic works, one chapter of the TV show and videos found in the web and we analyse the physics concepts found particularly about the issue electromagnetism. We developed the activity denominated Cine - Física in a public school from Rio Claro - SP, through presentations of these movies, shows and videos. Those works were exhibited in full and then we discussed the concepts involved in these movies. With the perform of this didactic proposal we verified that is possible insert the use of movies and videos in the classroom activities, and go beyond the entertainment or using those materials as supplements of classes. Dialoguing with students was possible to realize that they visualize the effects and physical concepts in a different way than other that used to be shown in the blackboard through formulas, providing positive effects to the learning of Physics

Experimental model of intestinal endometriosis: pilot study

Aims: The objective of this study is to create an experimental model of intestinal endometriosis in pigs, which might allow better understanding of deep infiltrating endometriosis and development of new treatment techniques. As secondary objective, we intend to create endometrial implants accessible by transrectal ultrasonography (TRUS). Study Design: Surgical experimental study in swine. Place and Duration of Study: This study was performed at the Instituto de Ensino e Pesquisa do Hospital Sírio-Libanês, São Paulo, Brazil, between January 2012 and December 2012. Methodology: Two sexually mature female minipigBR pigs underwent two laparotomies (each animal). The first laparotomy was performed to implant two fragments of autologous endometrium in the rectal wall. The second one was performed thirty days later to visualize, measure and obtain tissue of the site of the implants for histopathology study. A TRUS study was performed prior to the second surgery. The Institution’s Animal Utilization Study Committee approved the study. Results: In the first laparotomy a 5-cm segment of right uterine horn was resected. The endometrium was separated from the myometrium through sub-endometrial saline injection. Two endometrial fragments (1.0 x 2.0 cm) were dissected and sutured in the intra peritoneal anterior rectal wall of the animals. Thirty days later, all implants were identified during preoperative TRUS. “En-bloc” resection of the intestinal segment with the implants was performed during the second surgery. The autologous implants of endometrium invaded the muscular layer in one of the two animals. Conclusion: We demonstrated that the creation of an animal model of deep infiltrating endometriosis with intestinal involvement is feasible through a simple surgical technique. We believe that this model can be applied in experimental and clinical studies but further studies are necessary to refine the technique.

A citação no facebook: uma análise dialógica

This study analyses the quotations from a specific Facebook page called Brasileiríssimos, which presents itself as a project aiming to publicize and value the Brazilian culture. For this analysis one can observe the use of concepts of traditional quotations, to highlight, when comparing to these formats, the different ways of quoting that can be found on this means of communication: Facebook. The research aims to reflect about how the image of the page is built from the dialogue between the I and the other. More specifically, we look at the dialogue of the author of the page with the quoted text and the reader. In order to analyze that, concepts of quotation from authors belonging to Bakhtin's Circle are going to be used, amongst others. These concepts constitute the analysis criteria of the quoted texts, especially on how the quotation is made. The chosen methodological approach is a qualitative analysis from the quotations made on Facebook, as well as texts that help to visualize the dialogue between the traditional forms of quotation and the forms found on the abovementioned page. On the proposed dialogue about the concepts of quotation it is possible to notice the production of meaning caused by the way in which the quotation is made, by how the author of the page inserts herself in relation to the quoted text and, finally, by the relation of the text with the reader. Because this research bases itself on the dialogical discourse analysis, it be turned to the concept of dialogism, analyzing discourses in contact. Departing from there, one of the main goals is to understand which discourses dialogue when the production of the quotation and in what manner the quotation is made on the chosen means of communication

Aplicação da teoria da confiabilidade em estacas escavadas de grande diâmetro para obtenção das superfícies resistentes de projeto

In this work, the author looks forward to develop a new method capable of incorporate the concepts of the Reliability Theory and Ruin Probability in Deep Foundations, in order to do a better quantification of the uncertainties, which is intrinsic in all geotechnical projects, meanly because we don't know all the properties of the materials that we work with. Using the methodologies of Decourt Quaresma and David Cabral, resistance surfaces have been developed utilizing the data achieved from the Standard Penetration Tests performed in the field of study, in conjecture with the loads defined in the executive project of the piles. The construction of resistance surfaces shows to be a very useful tool for decision making, no matter in which phase it is current on, projecting or execution. The surfaces were developed by Kriging (using the software Surfer® 12), making it easier to visualize the geotechnical profile of the field of study. Comparing the results, the conclusion was that a high safety factor doesn't mean higher security. It is fundamental to consider the loads and resistance of the piles in the whole field, carefully choosing the project methodology responsible to define the diameter and length of the piles

Review of The Elemental Prairie: Sixty Tallgrass Plants (Watercolors and introduction) by George Olson

The Elemental Prairie provides a general discussion of the Great Plains and the tallgrass prairie for the general reader. Its botanically accurate plant drawings render a beautiful and artistic view into prairie plants. George Olson writes a compelling introduction about "Prairie Elements," painting a graphic verbal description about his trip into the prairie with noted prairie author John Madson. The introduction draws readers into the book and prepares them for John Madson's essay "The Running Country," an eloquent portrayal of the history of the tallgrass prairie. We are led into the hearts and minds of the pioneers who crossed the immense expanse of the Great Plains. Madson's descriptions of prairie plants help us visualize how the Great Plains looked prior to settlement, stirring us to see not only the allure of the prairies, but also the solitude and sometimes the loneliness. Madson mixes his personal experiences with current scientific theory of the formation of the prairies across the region, offering a way of seeing how the present fits into the past.

Stickiness in a bouncer model: A slowing mechanism for Fermi acceleration

Some phase space transport properties for a conservative bouncer model are studied. The dynamics of the model is described by using a two-dimensional measure preserving mapping for the variables' velocity and time. The system is characterized by a control parameter epsilon and experiences a transition from integrable (epsilon = 0) to nonintegrable (epsilon not equal 0). For small values of epsilon, the phase space shows a mixed structure where periodic islands, chaotic seas, and invariant tori coexist. As the parameter epsilon increases and reaches a critical value epsilon(c), all invariant tori are destroyed and the chaotic sea spreads over the phase space, leading the particle to diffuse in velocity and experience Fermi acceleration (unlimited energy growth). During the dynamics the particle can be temporarily trapped near periodic and stable regions. We use the finite time Lyapunov exponent to visualize this effect. The survival probability was used to obtain some of the transport properties in the phase space. For large epsilon, the survival probability decays exponentially when it turns into a slower decay as the control parameter epsilon is reduced. The slower decay is related to trapping dynamics, slowing the Fermi Acceleration, i.e., unbounded growth of the velocity.

Kidney of Minke Whale (Baleanoptera acutorostrata): Architecture and structure

Sarmento C. A. P., Ferreira A. O., Rodrigues E. A. F., Lesnau G. G., Rici R. E. G., Abreu D. K., Biasi C. & Miglino M. A. 2012. [Kidney of Minke Whale (Baleanoptera acutorostrata): Architecture and structure.] Rins de Baleia Minke (Baleanoptera acutorostrata): arquitetura e estrutura. Pesquisa Veterinaria Brasileira 32(8): 807-811. Departamento de Cirurgia, Setor de Anatomia dos Animais Domesticos e Silvestres, Universidade de Sao Paulo, Av. Prof. Dr. Orlando Marques de Paiva 87, Sao Paulo, SP 05508-270, Brazil. E-mail: sarmento@usp.br Among marine mammals, whale is one of the most attention-arousing animals, especially concerning its urinary tract. This system follows the pattern of mammals with regard to its constitution, however, it differs in renal morphology and number of lobes, which, in turn, form complete reniculi, agglutinated in hundreds. This structure is supported by fibrous connective tissue, but highly capable of maintaining electrolyte balance. Six pairs of kidneys of Minke whale (Balaenoptera acutorostrata), collected in 1982, in Cabedelo, Paraiba, Brazil, in the last fishing allowed, were dissected. These kidneys were preserved in 10% formaldehyde and they presented a very large histologic layer of collagen surrounding the medullary wall. The urinary collecting duct form papillary glasses, that reach a single collecting center which discharges in the ureter. It was found that the kidney of Minke whale has a lobe characteristic, with, on average, 700 reniculi; each reniculus has anatomical and functional characteristics of a unipyramidal kidney, with an inner layer (medulla), and an outer layer (cortex), and independent irrigation, with formation of individually arcuate arteries, as observed in unipyramidal terrestrial mammals. However, the set gathering all these reniculi constitutes, in the end, a multilobular and polipyramidal kidney, contrary to the morphology of most terrestrial mammals. It was not possible to distinguish the renicular cortex structures of the Minke whale in the level of light microscopy. Through scanning electron microscopy, it was possible to visualize a cortical layer located between two fibrous capsules. This joint, in turn, consists of connective tissue, which, along with a layer of collagen and elastic fibers, separates the cortex from the medulla; the kidney glomeruli were visualized, completely taken by the glomerular vessels and arranged into several layers. One notices that the glomerular cavity is almost a virtual space into which the glomerular filtrate is drained, and it does not present a globular shape. Vascularization is increased in the medullary region. The difference between the kidneys of terrestrial and marine mammals consists in the arrangement of morphological components, favoring the organ's physiology.

IMPLEMENTATION OF PROTECTED AREAS FORCENTRAL CORRIDOR OF ATLANTIC FORESTIN BAHIA: CHALLENGES AND LIMITS

In Brazil, Protected Areas (PAs) are considered the cornerstone for development of national strategies for biodiversity conservation. Considering this point of view we analyzed thirty protected areas belonging to Atlantic Central Corridor of Atlantic Forest in Bahia, aiming to identify and analyze its current level of implementation. Lemos de Sa and Ferreira (2000) methodology which consist of applying a standard scale, where the variation of the level of implementation conforms to a range of 0 to 5 points was used, with appropriate adaptations. After obtaining the data from the implementation level we use the aggregation method of Ward to help visualize the dissimilarity between the protected areas studied. We used an international classification proposed by IUCN (International Union for Conservation of Nature) for that the UCs to be compared with works done in another countries, the UCs considered are in the groups Ia, II, V and VI da IUCN. As results, 50% of protected areas analyzed are reasonably implemented, 40% inadequately implemented, 6.7% are presented only on paper and only 3.3% can be classified as satisfactorily implemented. These areas presents problems in their regularization; deficiency in infrastructure, human and financial resources. Given the results its clear the recurrent fact that conservation areas under study must be effectively implemented and for this to occur environmental policies should be focused on actions to consolidate the goals of conservation strategy.

Microendoscopic stereotactic-guided percutaneous radiofrequency trigeminal nucleotractotomy

Object. Over the past few decades, various authors have performed open or stereotactic trigeminal nucleotractotomy for the treatment of neuropathic facial pain resistant to medical treatment. Stereotactic procedures can be performed percutaneously under local anesthesia, allowing intraoperative neurological examination as a method for target refinement. However, blind percutaneous procedures in the region of the atlantooccipital transition carry a considerably high risk of vascular injuries that may bring prohibitive neurological deficit or even death. To avoid such complications, the authors present the first clinical use of microendoscopy to assist percutaneous radiofrequency trigeminal nucleotractotomy. The aim of this article is to demonstrate intradural microendoscopic visualization of the medulla oblongata through an atlantooccipital percutaneous approach. Methods. The authors present a case of severe postherpetic facial neuralgia in a patient who underwent the procedure and had satisfactory results. Stereotactic computational image planning for targeting the spinal trigeminal tract and nucleus in the posterolateral medulla was performed, allowing for an accurate percutaneous approach. immediately before radiofrequency electrode insertion, a tine endoscope was introduced to visualize the structures in the cisterna magna. Results. Microendoscopic visualization offered clear identification of the pial surface of the medulla oblongata and its blood vessels, the arachnoid membrane, cranial nerve rootlets and their entry zone, and larger vessels such as the vertebral arteries and the branches of the posterior inferior cerebellar artery. Conclusions. The initial application of this technique suggests that percutaneous microendoscopy may be useful for particular manipulation of the medulla oblongata, increasing the safety of the procedure and likely improving its effectiveness.

A Novel Method of Evaluating Ureteropelvic Junction Obstruction: Dynamic Near Infrared Fluorescence Imaging Compared to Standard Modalities to Assess Urinary Obstruction in a Swine Model

Purpose: Dynamic near infrared fluorescence imaging of the urinary tract provides a promising way to diagnose ureteropelvic junction obstruction. Initial studies demonstrated the ability to visualize urine flow and peristalsis in great detail. We analyzed the efficacy of near infrared imaging in evaluating ureteropelvic junction obstruction, renal involvement and the anatomical detail provided compared to conventional imaging modalities. Materials and Methods: Ten swine underwent partial or complete unilateral ureteral obstruction. Groups were survived for the short or the long term. Imaging was performed with mercaptoacetyltriglycine diuretic renogram, magnetic resonance urogram, excretory urogram, ultrasound and near infrared imaging. Scoring systems for ureteropelvic junction obstruction were developed for magnetic resonance urogram and near infrared imaging. Physicians and medical students graded ureteropelvic junction obstruction based on magnetic resonance urogram and near infrared imaging results. Results: Markers of vascular and urinary dynamics were quantitatively consistent among control renal units. The same markers were abnormal in obstructed renal units with significantly different times of renal phase peak, start of pelvic phase and start of renal uptake. Such parameters were consistent with those obtained with mercaptoacetyltriglycine diuretic renography. Near infrared imaging provided live imaging of urinary flow, which was helpful in identifying the area of obstruction for surgical planning. Physicians and medical students categorized the degree of obstruction appropriately for fluorescence imaging and magnetic resonance urogram. Conclusions: Near infrared imaging offers a feasible way to obtain live, dynamic images of urine flow and ureteral peristalsis. Qualitative and quantitative parameters were comparable to those of conventional imaging. Findings support fluorescence imaging as an accurate, easy to use method of diagnosing ureteropelvic junction obstruction.

Spatial analysis of leprosy incidence and associated socioeconomic factors

OBJECTIVE: To identify clusters of the major occurrences of leprosy and their associated socioeconomic and demographic factors. METHODS: Cases of leprosy that occurred between 1998 and 2007 in Sao Jose do Rio Preto (southeastern Brazil) were geocodified and the incidence rates were calculated by census tract. A socioeconomic classification score was obtained using principal component analysis of socioeconomic variables. Thematic maps to visualize the spatial distribution of the incidence of leprosy with respect to socioeconomic levels and demographic density were constructed using geostatistics. RESULTS: While the incidence rate for the entire city was 10.4 cases per 100,000 inhabitants annually between 1998 and 2007, the incidence rates of individual census tracts were heterogeneous, with values that ranged from 0 to 26.9 cases per 100,000 inhabitants per year. Areas with a high leprosy incidence were associated with lower socioeconomic levels. There were identified clusters of leprosy cases, however there was no association between disease incidence and demographic density. There was a disparity between the places where the majority of ill people lived and the location of healthcare services. CONCLUSIONS: The spatial analysis techniques utilized identified the poorer neighborhoods of the city as the areas with the highest risk for the disease. These data show that health departments must prioritize politico-administrative policies to minimize the effects of social inequality and improve the standards of living, hygiene, and education of the population in order to reduce the incidence of leprosy.
