A review of risk factors for hamstring injury in soccer: a biomechanical approach

The aim has been to review the literature about the risk factors of hamstring injury in soccer from a biomechanical point of view. METHODOLOGY. Data bases of bibliography references were Medline, Scopus and SportDiscuss. RESULTS AND DISCUSSION. Many prospective studies have shown that the previous injury is the greatest risk factor of sustaining the injury. However the primary causes of the injury are unclear in soccer. A lack of hamstring flexibility has been one of the main injury risk factors with controversies on the results. Imbalance of isokinetic force is a risk factor but electrical coactivation of all muscles participating during knee flexion and extension are unknown in football. While the importance of lumbopelvic-hamstrings muscles synchronization during running seems to be crucial for understanding the risk of injury, no research has been developed in this topic in football. CONCLUSIONS. More research using new data recording procedures as Dynamic Scanners, Surface EMG, Inverse Dynamic Analysis are needed. The analysis of more specific movements as running, kicking or jumping is clearly required. Managers, coaches, physical trainers, physiotherapists, sport physicians and researchers should work together in order to improve the injury prevention and rehabilitation programs of football players. Key Words: sports biomechanics, soccer, hamstring injury, risk factors

Henri Lefebvre: possibilidades teórico-metodológicas para Arquitetura e urbanismo

This paper presents the theoretical-methodological possibilities of the French philosopher and sociologist Henri Lefebvre, for the discipline of architecture and urbanism in an effort to overcome the fragmentation imposed by the institutionalization of science in general. From Du rural à l'urbain (Lefebvre, 1970) compilation, it brings the author's other works from the period between 1968 and 1974, indicating the conduits for reflection and their interrelationships with methods, types of analyses and other procedures to treat the space-time urban. The methodology involves a research on the author s 'today and yesterday' in the scientific field, a research and analysis of his procedures in highlight of philosophical, social, economic and political aspects, the historical context of his references and provides significant and possible elements for the study, research and extension in the area in question

Inserção da informática nos cursos de Arquitetura e Urbanismo do Brasil (1994 2006): diagnósticos, rebatimentos e perspectivas nas Instituições Federais de Ensino Superior do Nordeste: UFRN, UFPB e UFPE

This work supports the formalist education s improvement of the Brazilian architect and urban designer through a better application and systematization of the computer science s teaching potentialities. The research analyzes the discipline introduction in the Brazilian courses: Computer Science Applied to Architecture and Urbanism (InfoAU) in the Architecture and Urbanism Courses of Brazil (CAUs). It goes since the discipline was obligated by the MEC s Regulation nr. 1.770 from 1994 until the CNE/CES Resolution nr. 6 from 2006; it comprehends the discipline implantation, development and current context, in order to get more detailed, the research analyses three federal universities from the Northeast of the country: UFRN, UFPB and UFPE. Once identified the historical educational needs in the CAUs, the study focus on the computer science s increasing potential as an agent of integration, communication, development and knowledge/data management. It points out new social perspectives for a better use of this tool/mechanism, which adequately structuralized and integrated, creates propitious educational and professional performance/recycling conditions and a propeller instrument of research and extension activities. Among this work, it is suggested the aggregation of elements, which are complementary to the InfoAU discipline s reorganization, throughout a computerization s plan for the CAUs, extensive to the professional formation, generating a virtuous cycle in several activities of the academic, administrative and, research and extension s departments. Therefore, the InfoAU in the Brazilian CAUs context was analyzed; the main solutions and problems found were systemized; the possibilities of computer science s uses inside AU ware structuralized, InfoAU discipline s improvement plan was also defined, as well as strategies for the implementation of the computerization s plan for the CAUs, which would guarantee its maintenance in a continuity perspective

Estudo exploratório das percepções de irmãos e figuras parentais sobre o comportamento lúdico de pessoas com perturbação do espectro do autismo

Artigo 1: As pessoas com Perturbação do Espectro do Autismo (PEA) têm dificuldades sociais que impactam o desenvolvimento do comportamento lúdico (Naber et al., 2008). Os profissionais atentam pouco ao papel dos irmãos na família mas esta realidade pode influenciar a relação fraterna e carece de investigação. Este estudo analisou as percepções de 11 irmãos (5-12 anos) com desenvolvimento típico de pessoas com PEA (≥3 anos) sobre a interacção lúdica e identificou as suas necessidades a respeito da mesma. Foram conduzidas duas entrevistas: a Entrevista da Percepção dos Irmãos Acerca da Interacção Lúdica (EPI) junto dos irmãos para obter as percepções e a Entrevista para Recolha de Dados dos Participantes (ERDP) junto de uma figura parental para recolher dados sociodemográficos; os instrumentos foram elaborados pela equipa de investigação e submetidos a um estudo-piloto e validação por peritagem. Os dados sociodemográficos foram tratados no SPSS® 22 e as percepções foram submetidas a análise de conteúdo no MAXqda® 10 e sujeitas a validação. Os resultados obtidos indicam que as percepções sobre a interacção lúdica são predominantemente positivas e parecem conduzir ao interesse em aprender para satisfazer as necessidades existentes. As expectativas dos irmãos e a funcionalidade da comunicação constituem factores emergentes, bem como a ligação entre figuras e conteúdos de interesse na aprendizagem. Artigo 2: A relação fraterna exerce influência no sistema familiar e por isso deve ser feito um investimento no seu estudo. Entre pessoas com Perturbação do Espectro do Autismo (PEA) e os seus irmãos com desenvolvimento típico a interacção social pode apresentar desafios acrescidos e causar impacto na interacção lúdica. Este trabalho objectivou comparar as percepções de 11 irmãos e pais de pessoas com PEA (≥3 anos) acerca da interacção lúdica e eventuais necessidades para a melhorar, procurando diferenças e explorando factores emergentes. Foram elaboradas três entrevistas semi-estruturadas, testadas num estudo-piloto e submetidas à validação por expertise. Os irmãos responderam a uma entrevista de 31 questões referente às suas percepções acerca de tópicos relevantes na literatura. Os pais participaram numa entrevista com 35 questões com o mesmo objectivo e uma entrevista de 39 questões para recolher dados sociodemográficos. Os dados sociodemográficos foram analisados descritivamente e as percepções foram submetidas a análise de conteúdo. Os resultados foram interpretados em função da convergência e divergência dos relatos dos dois grupos de participantes e reforçam que existe uma tendência de divergência nas percepções dos dois grupos. As diferenças encontradas entre os grupos apontam para vários aspectos que devem ser tidos em conta na intervenção psicomotora junto das famílias de pessoas com PEA.

An overview of the submerged sea caves of Sagres (South of Portugal-Algarve)

The submerged sea caves of Sagres are located within the “Parque Natural do Sudoeste Alentejano e Costa Vicentina (PNSACV)” Marine Protected Area (MPA). This MPA integrates the national network of protected areas, addressed by the National Institute for Nature Conservation and Forest (ICNF) and was declared Site of Community Importance (SCI) under the Habitats Directive. Under the Annex I from the Habitat Directive these habitat caves are included in “8330 Submerged or partially submerged sea caves”. This conservation status should provide sufficient concern to have detailed information on biodiversity. However, among marine researcher, little is still known about these submerged sea caves and tunnels habitats. The only well-known study dealing with the Sagres sea caves was conducted in the late 80s and was only published in 2001. For effective management of such specific habitats a clear understanding of their localization and extension, the assessment of the biological communities, its conservation importance, its monitoring options and their sensitivity to natural change and human disturbance need to be a relatively clear. This report, produced under the MeshAtlantic Project, provides an overview of the available published and unpublished information relevant for the conservation management of the subtidal caves of Sagres. It mainly aims to be a base contribution for future studies.

Para la investigación se realizó un análisis de las narrativas transmedia, el ciberperiodismo y las características que definen a un periodista digital. Se procedió a conocer y posteriormente a realizar un estudio de recepción del medio de comunicación Comunica-Girón, que asienta su estructura funcional en la esfera digital, para lo cual se aplicaron métodos y técnicas de investigación de alcance descriptivo-exploratorio, proceso de observación, recopilación documental y tabulación de la información.

Grupo Totem: a infecção pela performance e a encenação performática

The issue of creating productions of hybrid matrices has demanded, for more than three decades, the attention of several theater theorists (COHEN: 1995; LEHMANN: 2007). The study of philosophers (DELEUZE & GUATTARI: 1995) has contributed for new concepts of the scene. These artistic practices, depending on the context, have been generating, more and more, new ways of staging. I will discuss the contamination caused by Antonin Artaud in contemporary theater, and the theater s infection by the performance, based on the thought of Barbara Browning (1995), from its capacity to penetrate and invade territories, and installs a new system. I affirm that the Totem Group (Recife PE) was contaminated by the performance and analyze two performative plays of the group, their points of convergence and separation. The first one is Ita, the search for the origin, the animal devir; the second is Caosmopolita, the body as a reflex of urbanity

Mover/se(r) a gênese do corpo entre/corpos e seus trajetos no processo coreográfico

This paper proposes a reflection on the body between/bodies, especially in contemporary dance, in their path that starts from the choreographic construction, permeating the body of the choreographer, the dancer s body and when fulfills themselves as artistic expression, the body of the spectator. Initially discusses the body in dance as a body/space for convergence, connectedness and continuity, from the thought of the Greek philosopher Epicurus of Samos, in dialogue with the thought of Maurice Merleau-Ponty, Gilles Deleuze and José Gil. Reflect about the creation of this body/space in the relationship choreographer/dancer using as connecting thread the experiences of the author in his artistic path. Finally describes the process of creating the scenic experiment (h)áporos, which constitutes the practice scene of this dissertation, having as main objective the creation of spaces of convergence and interaction between a proponent and an affluent body that, in this move, transforms itself and the space that now cohabits / is

Proposta de modelo de interação da Universidade Federal do Rio Grande do Norte e empresas do setor de petróleo

Operational procedures may negatively interfere in negotiation and execution regarding universities and business companies. In some cases it may even derail business interaction. Thus, aiming to overcome this and other barriers a university-industry interaction model was structured. The model enhances the appropriation of technological solutions on behalf of enterprises, as well as aim to improve the quality of teaching and research done at the university. In order to conduct a case study, sampling considering the Federal University of Rio Grande do Norte (UFRN) was made as well as the Oil and Gas sector. For data collection questionnaires, classroom observation, document analysis, semi-structured interviews were used. The study describes the companies as well as the internal organization of UFRN in their interaction context. The diagnosis related to past interactions as well as the expectations of the companies and the university s internal subjects regarding the university-industry relationship were also studied. Thus, specific questionnaires were applied for the three types of groups: researchers, managers and business companies. These subjects pointed out that the great deal of barriers they identified were related to issues regarding the university internal management. Given these barriers, the critical factors were then identified in order to overcome this reality. Among the nine critical factors only one belongs to the macro environment, while the remaining factors are related to organizational issues present in the university context. It was possible to formulate a university-business interaction model one the researched focused on the case study results and contribution from a theoretical framework that was enabled trough literature review. The model considers all business collaboration mechanisms; it focuses on a particular strategic productive sector and provides a co-evolution vision over time, according to the sector´s development strategy. The need for institutionalizing the relationship with the companies involved is pointed out. The proposed model considers all the critical factors identified by the research; it aims long-term relationship with the company and integrates teaching, research and extension actions. The model implementation was also considered. It was seen that it must be done in three phases. The phases will be defined by the level of maturity in the relationship between the university and the companies. Thus, a framework was developed in order to assess the interaction level regarding company institutionalization. Whilst structuring the model was a concern with replication came up. It was pointed out that this model should not only serve to this specific case study situation. So the final result is a model of university-industry relationship appropriate in the first instance, for UFRN, but has applicability, in general, to any Brazilian university

Coaching or gaming? Implications of strategy choice for home based stroke rehabilitation

Background: The enduring aging of the world population and prospective increase of age-related chronic diseases urge the implementation of new models for healthcare delivery. One strategy relies on ICT (Information and Communications Technology) home-based solutions allowing clients to pursue their treatments without institutionalization. Stroke survivors are a particular population that could strongly benefit from such solutions, but is not yet clear what the best approach is for bringing forth an adequate and sustainable usage of home-based rehabilitation systems. Here we explore two possible approaches: coaching and gaming. Methods: We performed trials with 20 healthy participants and 5 chronic stroke survivors to study and compare execution of an elbow flexion and extension task when performed within a coaching mode that provides encouragement or within a gaming mode. For each mode we analyzed compliance, arm movement kinematics and task scores. In addition, we assessed the usability and acceptance of the proposed modes through a customized self-report questionnaire. Results: In the healthy participants sample, 13/20 preferred the gaming mode and rated it as being significantly more fun (p < .05), but the feedback delivered by the coaching mode was subjectively perceived as being more useful (p < .01). In addition, the activity level (number of repetitions and total movement of the end effector) was significantly higher (p <.001) during coaching. However, the quality of movements was superior in gaming with a trend towards shorter movement duration (p=.074), significantly shorter travel distance (p <.001), higher movement efficiency (p <.001) and higher performance scores (p <.001). Stroke survivors also showed a trend towards higher activity levels in coaching, but with more movement quality during gaming. Finally, both training modes showed overall high acceptance. Conclusions: Gaming led to higher enjoyment and increased quality in movement execution in healthy participants. However, we observed that game mechanics strongly determined user behavior and limited activity levels. In contrast, coaching generated higher activity levels. Hence, the purpose of treatment and profile of end-users has to be considered when deciding on the most adequate approach for home based stroke rehabilitation.

Babxel: búsqueda multilingüe

La Web 2.0 ha tenido un enorme éxito gracias a la posibilidad de una interacción dinámica por parte del usuario, ya no sólo a la hora de participar en elementos colaborativos, como puedan ser los foros, sino en compartir/añadir contenido a la Web.

Layers of meaning: disentangling subject access interoperability

In order to facilitate subject access interoperability a mechanism must be built that allows the different controlled vocabularies to communicate meaning, relationships, and levels of extension and intension so that different user groups using different controlled vocabularies could access collections across the network. Switching languages, the tools of controlled vocabulary compatibility, consist of a single layer that does not allow for a flexible control of the semantic levels of meaning, relationships, and extension or intension. This paper proposes a multilayered conceptual framework wherein the levels of meaning, relationships and extension and intension are each controlled as individual parameters, rather than in a single switching language.
