A perspectiva dos fisioterapeutas que desenvolvem programas de educação postural com crianças bem jovens é que essas medidas de prevenção primária possam reduzir, a longo prazo a prevalência de dores nas costas.Esse estudo experimental, verificou os efeitos da educação postural comparando duas estratégias educacionais utilizando-se da pedagogia de uma história em quadrinhos (HQ) na retenção de informações desses hábitos posturais e de um circuito demonstrativo (CD), onde as crianças vivenciavam cada postura correta e incorreta. O programa de educação postural foi aplicado em três sessões educativas em escolares das 2ª e 3º séries, com idades entre 7-11 anos, de uma Escola Municipal, no Estado de São Paulo. A amostra consistiu de 80 crianças nos grupos HQ e CD. As sessões tiveram a duração de uma hora e serviram para transmitir noções básicas sobre: anatomia, biomecânica e fisiopatologia de dores na coluna vertebral e hábitos posturais corretos nas seguintes situações: postura sentada, postura em pé, postura deitada, transporte de mochila, técnica de levantamento e transferência de objetos. O conhecimento dos hábitos posturais foi verificado por intermédio de questionários aplicados antes do início do programa e após um período de 6 meses do término da pesquisa. Os resultados do estudo indicaram que para todas as variáveis estudadas não foram detectadas diferenças no aprendizado e memorização dos hábitos posturais corretos em ambos os sexos que se submeteram às duas metodologias de ensino, exceto no jeito de dormir, onde o índice de aumento das respostas corretas foi de 23% para o Circuito, enquanto o HQ apresentou apenas 7% / OBJECTIVE: This experimental study compared two educational strategies using the pedagogy of a comic book story (HQ) and a demonstration circuit (CD), to teach instructions for correct posture habits. METHOD: 80 students from the 2nd and 3rd grades of an elementary school in São Paulo city were studied using a questionnaire before and after the education program, and also six months after the end of the research, to assess the retention of the correct habits. RESULTS: The correct rates after the instructions increased 90% for both education strategies, except for the sleeping posture, which had more correct responses in the CD education practice. CONCLUSION: In the comparison between the comic book story and the demonstration circuit education strategies, both were effective in the memorization of correct postural habits

O processo de moldagem de pós injeção é utilizado para a fabricação de peças de geometrias complexas e com alto volume de produção. Em aplicações ortodônticas e médicas, nas quais são requeridas elevadas durezas e resistências à corrosão, o aço inoxidável 17-4 PH é utilizado aplicando-se aquela técnica de conformação. A atmosfera de sinterização é responsável pelo controle das reações químicas que ocorrem durante a densificação do material e são fundamentais para a qualidade final do produto. O objetivo deste trabalho foi avaliar a influência da atmosfera de sinterização na dureza e resistência à corrosão deste tipo de aço. A remoção dos ligantes primários foi realizada por meio de extração química utilizando-se um solvente com menor impacto ambiental, que se mostrou adequado a tal fim. A extração térmica posterior dos ligantes foi realizada pelo aquecimento nas temperaturas de 250°C e 450°C sendo, posteriormente, a temperatura elevada a 900°C, para o início da sinterização. Utilizou-se atmosferas de Nitrogênio, Vácuo e Hidrogênio, com temperaturas de sinterização de 1250°C e 1330°, com tempos de patamares de 30 e 60 minutos. Verificou-se que as densidades atingidas nas atmosferas de Hidrogênio e Vácuo são semelhantes e se adequaram às especificações requeridas pela norma, enquanto a atmosfera de Nitrogênio resultou em características inferiores. As durezas e as resistências à corrosão obtidas com o uso das atmosferas de Hidrogênio e Vácuo foram também superiores as das amostras sinterizadas em atmosfera de Nitrogênio. / The powder injection molding process is used to manufacture parts with complex shapes, with high production demand. In orthodontic and medical applications, in which high hardness and corrosion resistance are required, 17-4 PH stainless steel is used by applying this forming technique. The sintering atmosphere is responsible for controlling the chemical reactions that occur during material densification and is critical to the ultimate product quality. This research study aims at evaluating the influence of the sintering atmosphere on the hardness and corrosion resistance of this type of steel. The removal of the primary binder was carried out by chemical extraction applying a solvent with less environmental impact, which has proved to be suitable for this purpose. The subsequent binder thermal extraction was held by heating at temperatures of 250°C and 450°C and, therefore, at temperature of 900°C, to initiate sintering. Nitrogen, vacuum and hydrogen atmospheres were used with sintering temperatures at 1250°C and 1330°, with 30 and 60 minute-step time. It was verified that the densities achieved in hydrogen and vacuum atmospheres are similar and suitable by the regulations, whereas the nitrogen atmosphere resulted in lower performance. The hardness and corrosion resistance obtained with the use of hydrogen and vacuum atmospheres were also higher than those obtained for samples sintered in the nitrogen atmosphere.

However, few investigate the student look that still attends this level of education, and what these people expect of themselves for the near future with the way the determinants received from family and social relationships influence the young in your possible choice. Thus, this paper aims to identify the expectations of young students on their own destiny and the relationships involving their choices upon completion of high school. The study is an empirical research aimed to characterize individuals in socio-economic terms, in addition to showing existing profiles in the classroom and seek to know the social relations kept by the subjects in and out of school. Primarily aimed to understand the expectations of young high school students from public schools in the city of Campina Grande, Paraíba. Therefore we wish to observe how the environment and social groups such as family, school, among others, have a direct or indirect influence on the individual to choose the educational path and / or professional to be followed after completion at this level of education. The Pierre Bourdieu s concepts of cultural, social and economic capitals will be the work tab in the quest to understand how social origin and social relations are determining factors in the choice of the future of the individual. We also employ the concepts of primary and secondary socialization of Berger and Luckmann. The first form of socialization is responsible for the insertion of the individual in social media, and the second, by the process that introduces the individual already socialized into new sectors of society / Sucesso e fracasso escolar têm sido temas bastante comuns em trabalhos acadêmicos que pesquisam sobre estudantes egressos do ensino médio de escolas públicas ou privadas. Entretanto, poucos relacionam o olhar do estudante que ainda cursa esta etapa de ensino, e o que esses indivíduos esperam de si mesmos para um futuro próximo com a forma pela qual os determinantes recebidos dos familiares e das relações sociais influenciam o jovem na sua possível escolha. Sendo assim, este trabalho pretende identificar as expectativas de jovens estudantes sobre seu próprio destino e as relações que envolvem suas escolhas na conclusão do ensino médio. O estudo consiste numa pesquisa empírica que visa caracterizar os indivíduos em termos socioeconômicos, além de traçar os perfis existentes na sala de aula e procurar conhecer as relações sociais mantidas pelos sujeitos dentro e fora da escola. Prioritariamente buscamos identificar as expectativas de jovens estudantes do ensino médio de escolas públicas estaduais da cidade de Campina Grande, Paraíba. Pretendemos assim, constatar de que forma o meio e os grupos sociais, tais como a família, a escola, dentre outros, exercem influência direta ou indireta sobre o indivíduo na escolha do caminho educacional e/ou profissional que pretende seguir após a conclusão deste nível de ensino. Os conceitos de capital cultural, social e econômico de Pierre Bourdieu serão o guia do trabalho na busca de compreender como a origem social e as relações sociais são fatores determinantes na escolha do futuro do indivíduo. Também empregamos os conceitos de socialização primária e secundária de Berger e Luckmann. A primeira forma de socialização é responsável pela inserção do indivíduo nos meios sociais e, a segunda, pelo processo que introduz o indivíduo já socializado em novos setores da sociedade

Les Composés Organiques Volatils d’origine Biogénique (COVB) émis par la végétation représentent 1PgC.an-1 à l’échelle globale. Ces COVB, une fois émis dans l’atmosphère, peuvent participer à la formation d’ozone troposphérique ainsi qu’à la formation d’aérosols organiques secondaires et donc à la pollution atmosphérique. C’est pourquoi, il est important de quantifier le plus précisément possible les taux d’émissions de COVB et de mieux comprendre quels sont les facteurs environnementaux qui contrôlent ces émissions. Il est bien connu que les émissions de COVB sont contrôlées par la lumière et/ou la température mais elles peuvent également être influencées par d’autres facteurs comme le stress hydrique, bien que son impact soit encore mal compris. En effet, il a été montré que le déficit hydrique pouvait augmenter ou diminuer les émissions de COVB selon son intensité, sa durée et l’espèce étudiée. Dans le cadre du changement climatique, une intensification de la sécheresse est attendue en région Méditerranéenne avec une augmentation de la température, une diminution des pluies ainsi qu’une prolongation de la période de sécheresse. Ce changement climatique pourrait donc modifier les émissions de COVB. De plus, les effets d’une sécheresse appliquée sur plusieurs années sont encore mal connus. Dans cette étude, nous nous sommes intéressés à la réponse des émissions de COVB du chêne pubescent (Quercus pubcescens Willd.)face au stress hydrique attendu en région méditerrannéenne avec le changement climatique. / Biogenic Volatile Organic Compounds (BVOC) emitted by vegetation represent 1PgC.yr-1 at the global scale. These BVOC, once emitted into the atmosphere, can participate in the troposheric ozone formation as well as secondary oragnic aerosols and, consequently, on the atmospheric pollution. That’s why, it is very important to quantify, as accurately as possible, the BVOC emissions and to improbe the knowledge about the environmental factors which drive these emissions. It is well known that BVOC emissions are controlled by the light and the temperature but they can be impacted by other factors such as water stress. Nevertheless, these mechanisms are not well understood yet, since it has been shown that water stress can increase or decrease BVOC emissions according to the intensity and the duration of stress. In a context of climate change, we can expected an intensification of summer drought in Mediteranean area with an incerase of temperature, a decrease of rainfall as well as an elongation of stress period. This climate change could modify BVOC emissions. Moreover, the effects of a water stress applied during several years are not known. In this study, we wanted to evaluate the impact of water stress, expected with climate change, on BVOC emitted by Downy oak (Quercus pubescens Willd.), main isoprene emitter of Mediterranean region.

This thesis deals with the use of comic adaptations in literary lessons at primary and secondary schools. The aim of this work is to map available comic adaptations of literary works written by Czech authors. The comic adaptations of Franz Kafka's novella The Metamorphosis will be evaluated based on pre-selected criteria. Part of the work will also be a comparison of the original text with the selected comic adaptation and noting the changes in the fictional world created by transferring it to the comic medium. The work will help teachers to understand the theory of comics. Theoretical knowledge will be applied in the creation of two teaching blocks built for the purposes of literary education at primary and secondary schools. The concrete implementation of both teaching blocks in practice will be compared.

Šiame darbe apžvelgėme Vilniaus Universiteto Širdies ir kraujagyslių ligų klinikos Prevencinės kardiologijos poskyryje nuo įkūrimo sukauptą patirtį (1997-2008). Apibendrinome tyrimų rezultatus 1624 pacientams, sergantiems koronarine širdies liga, 977 įvairios kardiovaskulinės rizikos asmenims (sergantiems metaboliniu sindromu, cukriniu diabetu, dislipidemija, arterine hipertenzija, sveikiems kontroliniams), genetiniame projekte ištyrėme 67 šeimų 236 asmenis. Gyvensenos, rizikos veiksnių ir kardioprotekcinių vaistų vartojimo tyrimas koronarine širdies liga sergantiems pacientams 22 Europos šalyse išryškino esminius Lietuvos ir kitų šalių pacientų priežiūros skirtumus. Nustatėme, kad dauguma Lietuvos pacientų nepasiekia kardiovaskulinės prevencijos tikslų, ypač gydant dislipidemijas. Tyrimas leido daryti išvadą, kad Lietuvoje būtina ženkliai pakelti kardiovaskulinės prevencijos lygį. Tyrėme tradicinių rizikos veiksnių paplitimą tarp pacientų, sergančių koronarine širdies liga, ir parodėme, kad šie rizikos veiksniai dažnesni, nei nurodoma literatūroje. Mūsų duomenimis net 98% koronarinių pacientų turi bent vieną iš keturių tradicinių rizikos veiksnių. Du trečdaliai (66,5%) koronarine širdies liga sergančių jaunesnių pacientų (<55 metų) turėjo du ir daugiau rizikos veiksnius. Nustatėme statistiškai reikšmingą ryšį tarp aterosklerozės progresavimo vainikinėse arterijose ir kai kurių rizikos veiksnių: padidėjusio kraujospūdžio, gliukozės, homocisteino, lipoproteino (a), mažo...

We summarize the results of managing 1624 patients with coronary heart disease, 977 subjects with different cardiovascular risk (metabolic syndrome, diabetes, dyslipidaemia, arterial hypertension, healthy controls), evaluated 236 subjects from 67 families in the genetic project. A survey on the lifestyle, risk factors and use of cardioprotective drug therapies in patients with coronary heart disease from 22 European countries has showed major patient management differencies between Lithuania and other countries. The large proportion of patients in Lithuania do not achieve the targets for cardiovascular disease prevention, especially in lipid management. There is still considerable potential in Lithuania to raise standarts of cardiovascular prevention. We analyzed the prevalence of conventional risk factors among our patients with coronary heart disease and showed that they are more common than described in the literature. Our data revealed that 98% of coronary patients had at least one of four conventional risk factors. Two-thirds (66,5%) of younger patients (<55 years) with coronary heart disease had two and more risk factors. We have found statistically significant correlation between atherosclerosis progression rate in the coronary arteries and risk factors: elevated blood pressure, blood... [to full text]

Stress, a feeling of pressure, tension, strain or threat, is a problem for contemporary female participants in the primary and secondary educational milieus who automatically respond to stressors (causes of stress), in the same way as women and girls in the past, since human beings have not changed psychologically and biologically over the millennia. Like their ancestors many female educators, learners and caregivers today do not return to a calm mental and physical state after an initial stress reaction. They often remain under stress, which results in emotional, behavioural, physical and cognitive manifestations of stress. Moreover, females may be predisposed to stress because of psychological, biological and social factors that have underpinned their response to time-related stressors that have faced them throughout history. Yet, history has also shown that women and girls taught and learnt successful stress coping mechanisms. Insight into these universal truths may provide educational solutions to a universal problem / Educational Studies / D.Ed. (History of Education)

Cette thèse met en lumière deux points d'intérêt: l'Enseignement de la Géographie(EG) dans le cadre de l'Enseignement Fondamental et Moyen (EFM), et de même la formation d'enseignants de Géographie. Il s'agit ,dans cette thèse, d'apprendre comment le renouveau concernant la géographie, celle-ci nommée génériquement Géographie Critique (GC), a abouti au EFM. Les objectifs principaux de cette thèse ont été de rechercher comment le bouillonement et le renouveau de la Géographie, après 1978, sont-ils arrivés dans l'EG de l'EFM, et aussi quel est l'ap-port du mouvement GC dans le renouveau de l'EG et encore quelles sont les conceptions d’Education et de Géographie que les licenciés construisent pour et avec leurs apprenants au EFM. Pour atteindre ces objectifs, nous avons observé dix licenciés en Géographie, au cours des années 2002 et 2003, qui enseignaient dans l'EFM, des effectifs de treize écoles différentes, en trois journées distinctes de travail : matin, après-midi et soir. Nous avons complété 154 observations sur place, en totalisant 212 heures/classe. Nous avons constaté la grande difficulté dans la rénovation des pratiques pédagogiques, ainsi que dans la construction d'un bon support théorique qui puisse promouvoir un enseignement de la Géographie plus actuel, dynamique, pluriel, instigant, refléxif et radicalement démocratique. Ce travail n'a pas eu la pretention d'être prescriptible de « bien enseigner la Géographie », mais il a proposé servir de pretexte pour que la communauté de professeurs discutent et se posent des questions sur leurs référenciels de la Science, de l'Education et de la Géographie, pour fomenter la recherche d'un enseignement qui contribue au renforcement de l'autonomie intelectuelle de l'apprenant et aussi à la construction de la notion de citoyenneté qui établit la priorité de la lutte collective pour la démocracie, pour la liberté et pour la justice sociale à travers l'appropriation et la réflexion sur l'espace géographique et ses catégories d'analyse. Enfin, une Géographie qui pense á l'ontologie de l'être humain à partir de l'espace vécu. / Esta tese apresenta dois focos principais de interesse: o ensino de Geografia no Ensino Fundamental e Médio (EFM) e a formação de professores de Geografia. Nos interessamos, particularmente, em saber como o movimento de renovação da Geografia, genericamente denominado Geografia Crítica (GC), chegou ao EFM. Os objetivos principais desta tese foram averiguar como a efervescência e renovação da Geografia Acadêmica pós-1978 chegaram ao ensino de Geografia do EFM, qual a contribuição do movimento denominado GC na renovação do ensino desta disciplina e quais as concepções de Educação e de Geografia que os licenciados estão construindo com e para seus alunos do EFM. Para alcançar estes objetivos observamos dez licenciados em Geografia, nos anos de 2002 e 2003, que lecionavam no EFM, em treze escolas distintas nos turnos da manhã, tarde e da noite, na cidade de Porto Alegre, estado do Rio Grande do Sul, perfazendo um total de 154 (cento e cinqüenta e quatro) observações que totalizaram 212 (duzentas e doze) horas/aula. Constatamos a dificuldade de se renovar as práticas pedagógicas, bem como de se construir um bom embasamento teórico que promova um ensino de Geografia atual, dinâmico, plural, instigante, reflexivo e radicalmente democrático. Este trabalho não teve a pretensão de ser prescritivo do "bem ensinar Geografia", mas desejou servir de pretexto para que a comunidade de professores discuta e questione os seus referenciais de ciência, de Educação e de Geografia. para fomentar a busca de um ensino que auxilie o fortalecimento da autonomia intelectual do educando e a construção de uma noção de cidadania que priorize a luta coletiva pela democracia, pela liberdade e pela justiça social através da apropriação e da reflexão sobre o espaço geográfico e suas categorias de análise. Enfim, uma Geografia que pense a ontologia do ser humano a partir do espaço vivido. / This thesis has two main focuses: Geography teaching at primary and secondary schools and training of Geography teachers. Particularly, we are interested in how the movement of renewal of Geography - generally called Critical Geography - has arrived to primary and secondary teaching. The main targets of the thesis were to verify how the effervescence and renewal of post-1978 Academic Geography arrived to geography teaching at primary and secondary schools; the contribution of the so-called critical Geography movement to the renewal of that teaching; and the Education and Geography conceptions that geography teaching graduates are building with and for their students at the primary and secondary teaching. In order to reach those goals, we have observed ten such Geography graduates in 2002 and 2003. They taught at 13 distinct primary and secondary schools at morning, afternoon and evening classes in the city of Porto Alegre, in the southern Brazilian State of Rio Grande do Sul, totaling 154 observation sessions and 212 class-hours. We identified the difficulty to renew pedagogical practices as well as to build a good theoretical basis able to promote Geography teaching that is updated, dynamic, plural, encouraging, reflexive, and radically democratic. This work did not intend to prescribe "good Geography teaching". It rather wanted to serve as a pretext for the teacher community to discuss and question its references about science, Education, and Geography, in order to foster the search for teaching that helps to strengthen the intellectual autonomy of the student and the construction of a notion of citizenship that focuses on collective struggle for democracy, freedom and social justice through appropriation and reflection over the geographic space and its analytical categories. That is, geography that thinks human being's ontology based on the lived space.

Successful management of Environmental Education (EE) projects in schools is essential as it enhances teaching and learning in different subjects. The fact that EE is not a subject on its own, but is integrated into other subjects, has many detrimental effects with regard to the management of EE projects in schools. There are several barriers attached to the poor management of EE globally, in Africa and in South Africa. This study explored barriers to managing EE projects in Alexandra Township primary and secondary schools. This study was underpinned by total quality management theory. The research method used in the study followed a qualitative interpretative approach and data collection methods included a literature study, Participatory observation and open-ended questionnaires in order to examine the barriers to managing EE projects. Participants in the study were school principals, educators, subject facilitators and Institutional Development Support Officers (IDSOs). Findings indicated that, although school have EE projects, but there is a lack of competency and expertise in managing EE projects in schools. Non-governmental organisations are key role plays with expertise and competency in managing EE projects in schools. The study further indicated limited support offered by subject facilitators and IDSOs on how to manage EE projects in schools. However, there are number of factors that hinder successful management of EE projects in schools: these include lack of integration of EE into other subjects, lack of funds and other required resources, lack of time, and inadequate training. It was concluded that there were no systems in place that acted as a guideline for school principals and educators to overcome the barriers in EE project management in schools. It was concluded that school principals, educators and stakeholders, including subject facilitators and IDSO’s should work together in managing EE projects in schools. Hence, this study calls attention to the provision of in-service training for EE project management for school principals, educators, subject facilitators and IDSOs. Further, more relevant resources should be provided to schools in order to manage EE projects. / Science and Technology Education / D. Ed. (Didactics)
