Jogo de atividade física e aprendizagens escolares : um estudo sobre a relação entre recess, estatuto sociométrico e o desempenho escolar das crianças do 1º ciclo

A presente investigação examina a importância do recess enquanto parte integrante do quotidiano escolar, deslindando o seu contributo ao nível da aprendizagem, da capacidade de trabalho e do sucesso académico. A premissa de que a aprendizagem dos alunos sai beneficiada pela introdução de pausas no seio de longos períodos de trabalho intelectual, é comum a um sem número de teorias gizadas na literatura que, no entanto, deixam por esclarecer se o benefício provém do conteúdo da pausa, ou meramente da sua existência. De forma a contribuir para este debate, centra-se a presente investigação numa abordagem alternativa: partindo do pressuposto de que as características individuais dos alunos, nomeadamente o estatuto sociométrico, a idade e o género, condicionam a forma como ocupam o tempo que passam no recreio, constituiu-se uma amostra, seleccionada mediante a aplicação de um questionário sociométrico, e levou-se a cabo a observação das actividades por ela desenvolvidas no recreio e da performance por ela conseguida na sala de aula, antes e depois do intervalo. Concluiu-se que a forma como as crianças vivem o recess é fortemente influenciada pelas três variáveis chave (status sociométrico, género e nível de ensino), e que o conteúdo do intervalo, mais do que a sua simples existência, é determinante para a subsequente atitude na sala de aula. Ressalve-se, em particular, que os alunos cuja actividade no recreio se revela fisicamente intensa e socialmente Cooperativa e Associativa, por excelência os alunos Populares, experimentam maiores dificuldades de atenção e concentração no regresso à aula do que aqueles que vivem um recess marcado por níveis moderados de actividade física e por um comportamento social menos expansivo. Mais, constatou-se que a dimensão social do comportamento durante o recess monopoliza o seu conteúdo influenciando, como tal, o desempenho na sala de aula.

Suprapineal recess: an alternate site for third ventriculostomy? Case report.

This 30-year-old woman presented with clinical symptoms and signs of intracranial hypertension and Parinaud syndrome secondary to ventriculoperitoneal shunt dysfunction. Magnetic resonance (MR) imaging revealed gross triventricular hydrocephalus with a large suprapineal recess due to aqueductal stenosis. Using an endoscopic approach, a ventriculostomy was performed within the floor of the dilated suprapineal recess. Following this procedure the patient experienced alleviation of all her neurological symptoms and signs. Postoperative MR imaging and cerebrospinal fluid flow studies demonstrated a functioning ventriculostomy. The anatomy of the suprapineal recess and its suitability for endoscopic ventriculostomy are discussed.

Student Perspectives of the Context of Recess; Implications for Student Well-Being

With most students in Canada spending approximately 180 days a year in school, averaging more than six hours a day (Morrison & Kirby, 2011), Wei, Szumilas and Kutcher (2011) argue that this places educational institutions in an unique position in terms of influencing the health and well-being of students. This brings forth the need for school environments to be utilized in ways that are conducive to promoting student development. Much of the educational and developmental components embedded within the school system as well as experiences within greatly influence student’s health and well-being. A national statement was made a concerning American children’s education and mental health that is greatly applicable to the Canadian school system. It was stated that schools “must be active partners in the mental health care of our children” because of the “important interplay between emotional health and school success” (Lazarus & Sulkowski, 2011, pp. 15-16). This identifies the need to ensure that all students, as much as possible, are being provided with safe environments and sufficient support in order to encourage positive developmental trajectories of student health and well-being.

Peer Victimization and the Need to Belong within the Context of Recess

Within the school setting, recess is often reported as a frequent context for bullying (Vaillancourt et al. 2010), but is currently understudied. The present study utilized a mixed-methods approach in order to examine the frequency of peer victimization at recess and explore how the current context of recess relates to children’s sense of belonging. Participants included 464 students between grades 4 to 8 from nine Southern Ontario elementary schools. Self-report measures on peer victimization and belongingness were completed, along with open-ended questions regarding the recess context. Results demonstrated the frequencies of peer victimization at recess, the relationship between victimization and belonging, contextual factors that promote and impede belongingness at recess, and solutions to support children who feel left out.These findings provide further insight for educators and administrators in order to better support children who experience victimization within the recess context.

Playgrounds going wrong: study of the adult style and children's rights during recess in an early childhood and primary education center

Recent perspectives on Pedagogy for Early Childhood Education emphasize children's participation in line with the Children's Rights Convention. The study aimed to analyse how children's rights are dealt with during recess in a school (Early Childhood and Primary Education) in Portugal. The aims were: to characterize the style of the adult (teaching assistants) and the interactions that are established with the children at the playground/recess, and analyse them in terms of children's rights. The qualitative approach was based on the observation during the recess for three weeks. The Adult Style Observation Schedule for Early Childhood Education (ASOS-ECE) was used to register and code the dynamics of six teaching assistants (3 ECE and 3 PE). Critical incidents were also registered. Statistical analysis of the ASOS-ECE levels were complemented with the content analysis of the notes. The playground space was quite limited and affected children's play and well-being. The outdoor playground was never used for the Early Childhood classes, only for Primary Education students but with little supervision. Children were often deprived of playground time by decision of the teaching assistants, as punishment. The results obtained through the Adult Style Observation Schedule for Early Childhood Education (ASOS-ECE) are not satisfactory and are below what would meet the minimum quality value (3,5). For Early Childhood Education, sensibility is the most valued dimension but with very low levels (<2,5). For Primary Education it was autonomy that scored highest (<2,5). The analysis of the notes/critical incidents highlighted articles 12 (expression of own views), 13 (freedom of expression), 19 (protection against violence), 29 (development of personality) and 31 (rest and leisure, play and recreational activities) as being put into question by actions of the adults responsible for the children. Children's rights and well-being need to be put forward in the knowledge base for all adults working with children so that Pedagogy can fulfil its purpose fully.

Social competence at the playground: Preschoolers during recess

Social interactions at the playground have been represented as a rich learning opportunity to hone and master social skills at pre- school years. Specifically, all forms of social play (fantasy, role, ex- ercise or rough-and-tumble) have been related to children’s social competence. The main goal of this study was to examine whether it is a certain kind of social play which facilitates the development of social competence, or if it is just the opportunity for interacting during recess that provides children with an optimal environment for social learning. A total of 73 preschoolers (4–6 years old) were videotaped at the school’s playground. Teachers provided assess- ments of children’s social competence. Children’s interactions at the playground were assessed through an innovative measuring method, based on radio-frequency identification devices. The results showed a positive association between exercise play and children’s social competence. In contrast with the literature, both forms of pretend play, fantasy and role play were unrelated to children’s social competence. Smaller peer groups and longer interactions also demonstrated a positive association with these preschoolers’ social competence. The study shows the importance of outdoor physical play for preschoolers’ social success. More- over, the study suggests that the environment in which children play has an important effect on the adaptive nature of their play.

[the Modified Us7 Score In The Assessment Of Synovitis In Early Rheumatoid Arthritis].

To evaluate the modified US7 score (MUS7 score SYN) in the assessment of patients with early rheumatoid arthritis (ERA). In addition, dorsal and palmar recesses of the wrists as well as of small joints of the hands and feet were examined for the presence of synovitis by means of a global assessment of joints. The study sample comprised 32 patients treated for arthritis, with an average disease duration of 13 months. An ultrasound machine with high frequency transducer was used. Hands were also X-rayed and analysed by Larsen score. Out of the 832 examined joints, synovitis was detected in 173 (20,79%), tenosynovitis in 22 (4,91%), and erosions in 3 (1,56%). Synovitis was predominantly detected in the dorsal recess (73,38%) of MCP and PIP joints, when compared with palmar recess (26%). The presence of synovitis in the joints evaluated correlated with clinical (HAQ-DI, DAS28), laboratory (ACPA, RF, CRP), and ultrasound results (r = 0,37 to r = 0,42; p = 0,04 to p = 0,003). We found correlation of the MUS7 score SYN of the gray scale US or of the power Doppler US with DAS28 (PCR) values (r = 0,38; p = 0,0332), and with CRP results (r = 0,39; p = 0,0280), respectively. The dorsal recess, the wrist, and small joints can be considered as important sites to detect synovitis by the MUS7 score SYN in patients with ERA.

Sphenoid sinus symmetry and differences between sexes

Objectives: To evaluate the anatomic variations of neurovascular structures adjacent to the sphenoid sinus and their agreement between right and left sides as well as differences between sexes. Methods: Forty-five cadavers were dissected (24 men, and differences between sexes and agreement of anatomic variations of the sphenoid sinus between sides were analyzed. Results: The mean distance from the sphenoid sinus ostium to the anterior nasal spine was greater in males than in females by an average of 3.0 mm (p = 0.001) while the mean difference of distances between the right and left side was -1.1 +/- 3.1 mm. Female cadavers had a greater frequency of optic-carotid recess (p = 0.04) and dehiscence over the maxillary nerve (p = 0.02), as well as greater relative risk of optic nerve protrusion (p < 0.001), and dehiscence over the internal carotid artery (ICA) (p = 0.002). In male cadavers the intersinus septum was inserted on the course of the ICA 3.5 times more often than in female (p = 0.02). Agreement of anatomic variations between sides ranged from moderate to almost perfect depending on the structures evaluated. Conclusions: There are anatomic differences of the sphenoid sinus between sexes and between right and left sides, and these differences should be taken into consideration during surgery.

Quantitative Ventricular Neuroendoscopy Performed on the Third Ventriculostomy: Anatomic Study

BACKGROUND: One of the key elements for a successful endoscopic intervention in the ventricular system is the ability to recognize the anatomic structures and use them as a reference. OBJECTIVE: To measure the choroid plexus with endoscopy in the interventricular foramen, together with the structures on the third ventricle floor, and to compare these variables. METHODS: An observational prospective study was carried out on 37 brains of cadavers for which the cause of death was assessed at the Death Check Unit of the University of Sao Paulo in April 2008. This study was done on adults of both sexes with a rigid neuroendoscope. Endoscopic images were recorded, submitted for correction of distortion, and then measured. RESULTS: The measurements of the choroid plexus in the interventricular foramen, laterolateral distance of mammillary bodies, distance from the infundibular recess to the mammillary bodies, and area of the triangle in the tuber cinereum were 1.71 +/- 0.77 mm, 2.23 +/- 0.74 mm, 3.22 +/- 0.82 mm, and 3.69 +/- 2.09 mm(2), respectively. The ventricle floor was opaque in 84% of cases. The internal distance of mammillary bodies was absent in 89%. Associations between the translucent floor of the third ventricle and laterolateral distance of mammillary bodies, internal distance of mammillary bodies, and age were identified. CONCLUSION: Before this research, there was no record of the measurements of the choroid plexus in the interventricular foramen. The remaining variables of the present study show a greater number in normal brains compared with others.

Endoscopic Anatomy of the Pterygopalatine Fossa and the Transpterygoid Approach: Development of a Surgical Instruction Model

Introduction: The pterygopalatine fossa (PPF) is a narrow space located between the posterior wall of the antrum and the pterygoid plates. Surgical access to the PPF is difficult because of its protected position and its complex neurovascular anatomy. Endonasal approaches using rod lens endoscopes, however, provide better visualization of this area and are associated with less morbidity than external approaches. Our aim was to develop a simple anatomical model using cadaveric specimens injected with intravascular colored silicone to demonstrate the endoscopic anatomy of the PPF. This model could be used for surgical instruction of the transpterygoid approach. Methods: We dissected six PPF in three cadaveric specimens prepared with intravascular injection of colored material using two different injection techniques. An endoscopic endonasal approach, including a wide nasoantral window and removal of the posterior antrum wall, provided access to the PPF. Results: We produced our best anatomical model injecting colored silicone via the common carotid artery. We found that, using an endoscopic approach, a retrograde dissection of the sphenopalatine artery helped to identify the internal maxillary artery (IMA) and its branches. Neural structures were identified deeper to the vascular elements. Notable anatomical landmarks for the endoscopic surgeon are the vidian nerve and its canal that leads to the petrous portion of the internal carotid artery (ICA), and the foramen rotundum, and V2 that leads to Meckel`s cave in the middle cranial fossa. These two nerves, vidian and V2, are separated by a pyramidal shaped bone and its apex marks the ICA. Conclusion: Our anatomical model provides the means to learn the endoscopic anatomy of the PPF and may be used for the simulation of surgical techniques. An endoscopic endonasal approach provides adequate exposure to all anatomical structures within the PPF. These structures may be used as landmarks to identify and control deeper neurovascular structures. The significance is that an anatomical model facilitates learning the surgical anatomy and the acquisition of surgical skills. A dissection superficial to the vascular structures preserves the neural elements. These nerves and their bony foramina, such as the vidian nerve and V2, are critical anatomical landmarks to identify and control the ICA at the skull base.

The distribution and morphological characteristics of serotonergic cells in the brain of monotremes

The distribution and cellular morphology of serotonergic neurons in the brain of two species of monotremes are described. Three clusters of serotonergic neurons were found: a hypothalamic cluster, a cluster in the rostral brainstem and a cluster in the caudal brainstem. Those in the hypothalamus consisted of two groups, the periventricular hypothalamic organ and the infundibular recess, that were intimately associated with the ependymal wall of the third ventricle. Within the rostral brainstem cluster, three distinct divisions were found: the dorsal raphe nucleus (with four subdivisions), the median raphe nucleus and the cells of the supralemniscal region. The dorsal raphe was within and adjacent to the periaqueductal gray matter, the median raphe was associated with the midline ventral to the dorsal raphe, and the cells of the supralemniscal region were in the tegmentum lateral to the median raphe and ventral to the dorsal raphe. The caudal cluster consisted of three divisions: the raphe obscurus nucleus, the raphe pallidus nucleus and the raphe magnus nucleus. The raphe obscurus nucleus was associated with the dorsal midline at the caudal-most part of the medulla oblongata. The raphe pallidus nucleus was found at the ventral midline of the medulla around the inferior olive. Raphe magnus was associated with the midline of the medulla and was found rostral to both the raphe obscurus and raphe pallidus. The results of our study are compared in an evolutionary context with those reported for other mammals and reptiles. Copyright (C) 2002 S. Karger AG, Basel.

Effect of Adherend Recessing on the Tensile Strength of Single Lap Joints

Bonded joints are gaining importance in many fields of manufacturing owing to a significant number of advantages to the traditional methods. The single lap joint (SLJ) is the most commonly used method. The use of material or geometric changes in SLJ reduces peel and shear peak stresses at the damage initiation sites. In this work, the effect of adherend recessing at the overlap edges on the tensile strength of SLJ, bonded with a brittle adhesive, was experimentally and numerically studied. The recess dimensions (length and depth) were optimized for different values of overlap length (LO), thus allowing the maximization of the joint’s strength by the reduction of peak stresses at the overlap edges. The effect of recessing was also investigated by a finite element (FE) analysis and cohesive zone modelling (CZM), which allowed characterizing the entire fracture process and provided joint strength predictions. For this purpose, a static FE analysis was performed in ABAQUS1 considering geometric nonlinearities. In the end, the experimental and FE results revealed the accuracy of the FE analysis in predicting the strength and also provided some design principles for the strength improvement of SLJ using a relatively simple and straightforward technique.
