Incremento da aptidão física em jovens adolescentes no contexto escolar pela implementação de um programa de treino da força

Introdução O treino da força, numa perspetiva de melhoria da aptidão física, deve ser uma abordagem essencial dos programas de educação física (EF). Isto porque sem o seu desenvolvimento, assim como o incremento do desempenho das habilidades motoras, muito dificilmente se pode assegurar uma participação gratificante na atividade física e desportiva futura, com o prejuízo que daí advém para a saúde, bem-estar, confiança e vigor, da nossa juventude. Parece-nos, por outro lado, que a escola é o espaço ideal de desenvolvimento deste objetivo, pelas duas principais razões: (i) é o local universal por onde passam todas as nossas crianças e jovens; (ii) reúne condições excecionais, porque possui instalações razoáveis e materiais para a sua prática e porque dispõe de especialistas que podem assegurar a elevada qualidade de conceção e supervisão dos programas de treino (PT). Metodologia Participaram neste estudo 123 alunos do 12º ano, divididos em grupo controlo (n=31) e experimental (n= 92). Foram realizados os seguintes testes: push-up 60”, curl-up 30”, lançamento da bola medicinal (BM) com 2kg, sêxtuplo, impulsão e 30 m sprint. Os PT eram constituído por elevação gémeos, afundos, semi-agachamento, supino, butterfly, remo vertical, burpees, kettlebell, abdominais e lombares (2x15 repetições ca.60% 1 RM, durante 30” e 60” descanso). Os PT tiveram a duração de 9 semanas com 2 unidades de treino. Resultados Ambos os grupos melhoraram os seus valores médios em relação ao segundo momento da avaliação, no entanto, somente o grupo experimental apresentou ganhos estatisticamente significativos em 4 dos 6 testes aplicados, concretamente: push-up, lançamento BM, impulsão vertical e sêxtuplo. Conclusões Este estudo evidencia que as aulas de EF com um enfoque na organização e aplicação de PT de força, induzem a ganhos superiores, daí se dever realçar a importância da implementação do treino da força no contexto escolar.

O Abuso Sexual de Crianças e a Criança no Papel de Testemunha

O presente estudo pretende explorar a perceção dos profissionais de saúde mental acerca do crime de abuso sexual de crianças e as competências da criança no papel de testemunha, centrando-se para tal, na identificação das crenças e mitos existentes entre os participantes, no âmbito dessa problemática. Esta investigação pretende assim alargar o conhecimento relativamente a esta temática, enfatizando o facto de que qualquer profissional pode ratificar mitos de abuso sexual e que isso pode interferir nas suas atitudes perante a atribuição de credibilidade à criança. Os dados foram obtidos através da técnica da entrevista, como recurso a uma entrevista semi-estruturada e um questionário sócio-demográfico. Foram analisadas 11 entrevistas de uma amostra constituída por 9 psicólogos, 1 psiquiatria e 1 pedopsiquiatria, sendo 8 participantes dos sexo feminino e 3 do sexo masculino. Da análise realizada observou-se que os participantes detêm crenças adequadas quanto à situação abusiva; aos motivos para a criança não revelar a situação abusiva ou revelar apenas tardiamente; e quais os fatores que estão implicados/ afetam as competências da criança, enquanto testemunha credível. Por sua vez, os mitos observados surgiram relativamente ao agressor, acreditando que os abusadores apresentam caraterísticas distintas das outras pessoas e/ou doença mental e que abusam de crianças e/ou adolescentes motivados por um gosto padrão; relativamente às vítimas, acreditando que os rapazes adolescentes podem defender-se do abuso e que os adolescentes são abusados por terem caraterísticas semelhantes aos adultos; e sobre as caraterísticas do testemunho realizado pela criança, acreditando que as crianças não mentem sobre situações de abuso sexual e que não podem recordar/reportar de forma fidedigna eventos que aconteceram há muito tempo.

Meningencefalites bacterianas agudas em crianças: complicações e sequelas neurológicas

We studied 271 children under age of 15 with diagnosis of acute bacterial meningencephalitis treated at Medical School in Ribeirão Preto, University of São Paulo, between 1980 and 1990. The patients were divided in two groups: 1) those who had not received previous antibiotics treatment (NTP), with 153 cases; and 2), those who had received previous antibiotics treatment (PT), with 118 cases. The etiological agent was more frequently identified in NPT group, while ventriculitis was more frequent in PT group. Mortality rate accounted for 19,5% of all cases, and 29.7% of children under 12 months of age. Acute meningitis caused by Streptococcus pneumoniae was frequently followed by increased mortality. Convulsive disorders and hemiparesis predominante among children under 12 months of age. On the neurosurgical point of view, ventriculitis, subdural hygroma, hydrocephalus, subdural empyema and brain abscess were identified and treated

O desenvolvimento do texto dissertativo em crianças da 4ª série

This reaserch analysed the developmental stage of fourth grade (primary school) children in ability of writting argumentative texts joint with their context. The reason of this reaserch is the lack of new studies in linguistical area and high ratio of unable students to make this kind of text. It will be showed the analysis of making text by public schools children for three months. These data were analysed trying identify argumentative operators, the kinds of arguments used and the stage of the argumentative ability of these children.

This fact obviously will make easier the development of their critical point of view, helping the students to think about their living social reality.

Saúde dos adolescentes: um estudo de base populacional em Campinas, São Paulo, Brasil

We estimated the prevalence of chronic diseases and other health problems reported by adolescents in relation to social and demographic variables and nutritional status. This cross-sectional population-based survey analyzed data from the Health Survey in Campinas, São Paulo State, Brazil, 2008. We used descriptive statistics and associations between variables with the chisquare test. Prevalence of chronic diseases among adolescents was 19.17%, with asthma showing the highest prevalence (7.59%), followed by heart disease (1.96%), hypertension (1.07%), and diabetes 0.21%. Prevalence rates were 61.53% for health problems, 40.39% for allergy, and 24.83% for frequent headache or migraine. After multivariate analysis using Poisson regression, the factors associated with chronic disease were age 15 to 19 years (PR = 1.38), not attending school (PR = 1.46), having children (PR = 1.84), and obesity (PR = 1.54). Female gender (PR = 1.12) was statistically associated with health problems. The study illustrates that adolescence is a life stage in which chronic disease and health problems can occur.

Insegurança alimentar em domicílios brasileiros com crianças menores de cinco anos

This article analyzes food insecurity and hunger in Brazilian families with children under five years of age. This was a nationally representative cross-sectional study using data from the National Demographic and Health Survey on Women and Children (PNDS-2006), in which the outcome variable was moderate to severe food insecurity, measured by the Brazilian Food Insecurity Scale (EBIA). Prevalence estimates and prevalence ratios were generated with 95% confidence intervals. The results showed a high prevalence of moderate to severe food insecurity, concentrated in the North and Northeast regions (30.7%), in economic classes D and E (34%), and in beneficiaries of conditional cash transfer programs (36.5%). Multivariate analysis showed that the socioeconomic relative risks (beneficiaries of conditional cash transfers), regional relative risks (North and Northeast regions), and economic relative risks (classes D and E) were 1.8, 2.0 and 2.4, respectively. Aggregation of the three risks showed 48% of families with moderate to severe food insecurity, meaning that adults and children were going hungry during the three months preceding the survey.

O comportamento de crianças durante atendimento odontológico

This research intended to investigate the use of diazepam in conjunction with behavioral strategies to manage uncooperative behavior of child dental patients. The 6 participants received dental treatment during 9 sessions. Using a double-blind design, children received placebo or diazepam and at the same time were submitted to behavior management produces (distraction, explanation, reinforcement and set rule and limits). All sessions were recorded in video-tapes biped in 15 seconds intervals, in which observers recorded child's (crying, body and/or head movements, escape and avoidance) and dentist's behavior. The results indicated that diazepam, considering the used dose, was only effective with one subject. The other participants didn't permit the treatment and showed an increase in their resistance. The behavioral preparation strategies for dental treatment should have been more precisely planned in order to help the child to face the real dental treatment conditions mainly in the first sessions avoiding to reinforce inappropriate behaviors.

Formação de conceitos em crianças cegas: questões teóricas e implicações educacionais

Concept formation depends on language and thought, that promote the integration of information coming from the senses. It is postulated that changes in the person, the objects and events to be known suggest flexible models of concept teaching. It is assumed that the same considerations apply to teaching concepts to blind pupils. Specificities of this process are discussed, including the role of touch as resource, although not as a direct substitute to vision, and the notion of representation as a basis for the elaboration of pedagogical resources for the blind student.

Implante coclear em crianças: a visão dos pais

The objective of this study was to analyze the point of view of parents in relation to the cochlear implant, their level of information concerning the implant, its risks and benefits, and their expectations towards their children's future. Ten parents of deaf children candidate for the cochlear implant at Unicamp's Clinical Hospital were interviewed. Based on a qualitative approach, a content analysis showed that the majority of parents seek the cure for deafness, and consequently, the acquisition of speech with the cochlear implant. For these families, the cochlear implant is seen both as the solution to their children's deafness and as a path for a better future. It has been evidenced that during the acquisition of knowledge about the implant, parents experienced anxiety and anguish when faced with the risks and benefits of the procedure, and the need to choose between performing and not performing the cochlear implant.

This article aims at discussing about the foreign language teaching to young learners, taking the principles of the Sociocultural Theory (Vygotksy, 1978) and of the Communicative Approach (Almeida Filho, 1993, 2005) related to Primary English teaching (Cameron, 2001; Brewster, Ellis & Girard, 2002) as a theoretical references. Considerations about the importance of language learning in childhood will be made, as well as about the role of the grammar, oral language and mother tongue in the process. Likewise, the importance of Teacher Education will be briefly approached. This work is ended with the discussion about some possible procedures in the language teaching processes followed by a brief presentation of possible guidelines based on the bakhtinian notion of discourse genres.

Modelos organizadores do pensamento: uma perspectiva de pesquisa sobre o raciocínio moral com adolescentes autores de infração

This article has the aim to expand the perspective of research in the field of morality. We present a proposal of morality study of outlaw teenagers according to Thinking Organizer Models Theory. Through the idea of complexity we search to understand the cognitive process in the elaboration of moral reasoning inside situations of conflict. With this perspective, we developed a research that aimed to identify which organizer models were applied by 20 outlaw male teenagers who abide by social punishment to solve the hypothetical moral conflicts. Through interviews we told them a situation of moral conflict that involved friendship relation, physical aggression and steal. We could identified several models which were joined in three categories. Such models reflected the diversity and regularity that are present inside the elaborated reasoning to solve the conflicts shown by us. We conclude that the diversity of organizer models identified shows the importance of the contents in the construction of moral reasoning.

O comportamento de crianças em tratamento odontológico: intervenção psicofarmacológica

The present investigation evaluated the effects of diazepam used to manage uncooperative behavior of child dental patients. Six participants received placebo or diazepam (0,3 mg/kg weight) before formal dental treatment at total 54 sessions that were all recorded in videotapes. The analysis of recorded child (crying, body and/or head movements, escape and avoidance) and dentist's behavior management procedures (distraction, explanation, positive reinforcement) indicates no differences by using a double-blind Wilcoxon design (p>0.05). It is suggested the necessity of methodological refinement in studies that combine psychological and pharmacological handling strategies.

Comparação preliminar entre ultrassonografia quantitativa de falanges e densitometria óssea na avaliação da massa óssea em adolescentes

OBJECTIVE: To evaluate the association between quantitative ultrasonography at hand phalanges (QUS) and dual energy X-ray absorptiometry (DXA), and between these methods with food intake and history of bone fractures. SUBJECTS AND METHODS:After two years of follow up of 270 schoolchildren, 10 of them, who showed bone mass below - 2 SD in QUS, were included in the present study. Laboratory results and DXA data were analyzed. RESULTS: Bone mass evaluated by DXA at L1-L4 ranged from -2.8 to -1.1 SDS, and whole body bone mass, from -2.9 to -1.2 SDS. Three children had history of non-pathological bone fractures. Dietary assessment showed low intake of calcium in 10 cases, of phosphorus in 6, and of vitamin D in 8 cases. There were no differences among the cases of bone mass below-2 SD in any of the three used methods. There was no association between history of bone fractures and food intake, and between these evaluations and bone mass. CONCLUSION: In this small group of schoolchildren there was an association between the methods QUS and DXA. However, there was no association between bone mass and the history of bone fractures, or calcium, phosphorus and vitamin D intake.
