Perfil sociodemográfico dos idosos nas capitais do Nordeste e a mortalidade por doenças crônico-degenerativas desse segmento populacional em Natal (RN)

Population aging is a global demographic trend. This process is a reality that merits attention and importance in recent years, and cause considerable impact in terms of greater demands on the health sector, social security and special care and attention from families and society as a whole. Thus, in the context of addressing the consequences of demographic transition, population aging is characterized as a major challenge for Brazilian society. Therefore, this study was conducted in two main objectives. In the first article, variables of socioeconomic and demographic contexts were employed to identify multidimensional profiles of elderly residents in the Northeast capitals, from specific indicators from the 2010 Census information Therefore, we used the Grade of Membership Method (GoM), whose design profiles admits that an individual belongs to different degrees of relevance to multiple profiles in order to identify socioeconomic and demographic factors associated with living conditions of the elderly in the Northeastern capitals. The second article examined the possible relationship between mortality from chronic diseases and socio-economic indicators in the elderly population, of the 137 districts in Natal, broken down by ten-year age groups (60 to 69 years, 70-79 years and 80 and over. The microdata from the Mortality Information System (SIM), was used, provided by the Health Secretariat of Christmas, and population information came from the Population Census 2010. The method refers to the Global and Local Index neighborhood logic (LISA) Moran, whose spatial distribution from the choropleth maps allowed us to analyze the mortality of the elderly by neighborhoods, according to socioeconomic and demographic indicators, according to the presence of special significance. In the first article, the results show the identification of three extreme profiles. The Profile 1 which is characterized by median socioeconomic status and contributes 35.5% of elderly residents in the area considered. The profile 2 which brings together seniors with low socioeconomic status characteristics, with a percentage of 24.8% of cases. And the Profile 3 composing elderly with features that reveal better socioeconomic conditions, about 29.7% of the elderly. Overall, the results point to poor living conditions represented by the definition of these profiles, mainly expressed by the results observed in more than half of the northeastern elderly experience a situation of social vulnerability given the large percentage that makes up the Profile 1 and Profile 2, adding 60% of the elderly. In the second article, the results show a higher proportion of elderly concentrated in the neighborhoods of higher socioeconomic status, such as Petrópolis and LagoaSeca. Mortality rates, according to the causes of death and standardized by the empirical Bayesian method were distributed locally as follows: Neoplasms (Reis Santos, New Discovery, New Town, Grass Soft and Ponta Negra); Hypertensive diseases (Blue Lagoon, Potengi, Redinha, Reis Santos, Riverside, Lagoa Nova, Grass Soft, Neópolis and Ponta Negra); Acute Myocardial Infarction (Northeast, Guarapes and grass Soft); Cerebrovascular diseases (Petrópolis and Mother Luiza); Pneumonia (Ribeira, Praia do Meio, New Discovery, Grass Soft and Ponta Negra); Chronic Diseases of the Lower Way Airlines (Igapó, Northeast and Thursdays). The present findings at work may contribute to other studies on the subject and development of specific policies for the elderly.

A crença sobre a morte e o coping religioso-espiritual em pacientes internados com doenças crônicas

The human being is understood as an integral being, complex, which has multiple dimensions: social, biological, psychological, anthropological, spiritual and others. As its biological dimension, the man presents the possibility of physical illness, which means that the body requires care. The sick away from humans in health and safety conditions, approaching them directly from the finitude and vulnerability condition, leading us to contact the major uncertainties of life: suffering of disease and death. Religiosity and spirituality are important coping strategy for human when faced with borderline situations. When people turn to religion to cope with stress is the religious and spiritual coping. The objective of this research was to evaluate the relationship between the views on death and the religious-spiritual coping in patients with chronic diseases hospitalized. The study included ten patients hospitalized for chronic disease complications Medical Clinic Unit of a public hospital in the city of Uberlândia/MG. two psychological scales were used: Scale Religious-Spiritual Coping Brief (CRE-Brief Scale) and Scale Brief Diverse Perspectives of Death and a structured interview (audiogravada) on the subject of death and religious and spiritual coping. The results indicated that 80% of the sample (N = 8) consisted of patients hospitalized due to chronic diseases, while 20% accounted for patients with AIDS complications. Analyzing the results of scale CRE-Brief, it emphasizes the use of strategies of religious and spiritual coping by participants as compared to CRE Total, all study participants had average or high scores for this index, with a low utilization CRE negative and average utilization CRE Positive. Regarding views on death, the results obtained by the Different Perspectives Quick Scale on Death suggest that this sample agrees with the view death as something that is part of the natural cycle of life (M8 - Death as a natural end) and features the prospect of death as uncertainty, mystery and ignorance (M4 - death as Unknown). The correlations between the measures the factors and items of CRE-Bref and dimensions of Short scales on different perspectives of Death notes the prevalence of correlations of M4 dimensions - Death as unknown and M8 - Death as a natural order to the creditor scale soon. In the interview analysis revealed a positive influence of religion/ spirituality on health, from the perspective of the respondent, highlighting the protection promoted by religion. It also noticed the use of prayer as a coping strategy of hospitalization and illness. Regarding the interview about the topic of death, there was a predominance of issues related to "afterlife", "unknown" and "abandonment", which are associated with the visions of death and mystery and death as a natural end. In the interviews there belief clues about death as a terrifying mystery connected, so the unknown and the feeling of fear on the same. The experience of illness can therefore be considered as a source of vulnerability, since it is present personal perception of danger (external) - own illness and possible death, especially in those patients undergoing ICU - and where control is insufficient for the sense of security, since the hospital providing care to the patient are delegated to third parties and patients assume a passive role. This fact is important and relevant to health professionals who deal daily with patients hospitalized for chronic diseases, since the recourse to religion and spirituality as a coping strategy that psychic movement was not constituted in a form of negative distance or even denial of health condition. On the contrary, it refers to a movement in search of comfort and security provided by the religion and spirituality.

Influence of the sputtering flow regime on the structural properties and magnetic behavior of Fe-Ga thin films (Ga ∼ 30 at.%)

In this paper we analyze the structure of Fe-Ga layers with a Ga content of ∼30 at.% deposited by the sputtering technique under two different regimes. We also studied the correlation between the structure and magnetic behavior of the samples. Keeping the Ar pressure fixed, we modified the flow regime from ballistic to diffusive by increasing the distance between the target and the substrate. X-ray diffraction measurements have shown a lower structural quality when growing in the diffusive flow. We investigated the impact of the growth regime by means of x-ray absorption fine structure (XAFS) measurements and obtained signs of its influence on the local atomic order. Full multiple scattering and finite difference calculations based on XAFS measurements point to a more relevant presence of a disordered A2 phase and of orthorhombic Ga clusters on the Fe-Ga alloy deposited under a diffusive regime; however, in the ballistic sample, a higher presence of D0_3/B2 phases is evidenced. Structural characteristics, from local to long range, seem to determine the magnetic behavior of the layers. Whereas a clear in-plane magnetic anisotropy is observed in the film deposited under ballistic flow, the diffusive sample is magnetically isotropic. Therefore, our experimental results provide evidence of a correlation between flow regime and structural properties and its impact on the magnetic behavior of a rather unexplored compositional region of Fe-Ga compounds.

MOVPE growth and characterization of Al(Ga)N and InAlN/AlGaN quantum wells for UV LED applications

The study of III-nitride materials (InN, GaN and AlN) gained huge research momentum after breakthroughs in the production light emitting diodes (LEDs) and laser diodes (LDs) over the past two decades. Last year, the Nobel Prize in Physics was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for inventing a new energy efficient and environmental friendly light source: blue light-emitting diode (LED) from III-nitride semiconductors in the early 1990s. Nowadays, III-nitride materials not only play an increasingly important role in the lighting technology, but also become prospective candidates in other areas, for example, the high frequency (RF) high electron mobility transistor (HEMT) and photovoltaics. These devices require the growth of high quality III-nitride films, which can be prepared using metal organic vapour phase epitaxy (MOVPE). The main aim of my thesis is to study and develop the growth of III-nitride films, including AlN, u-AlGaN, Si-doped AlGaN, and InAlN, serving as sample wafers for fabrication of ultraviolet (UV) LEDs, in order to replace the conventional bulky, expensive and environmentally harmful mercury lamp as new UV light sources. For application to UV LEDs, reducing the threading dislocation density (TDD) in AlN epilayers on sapphire substrates is a key parameter for achieving high-efficiency AlGaNbased UV emitters. In Chapter 4, after careful and systematic optimisation， a working set of conditions, the screw and edge type dislocation density in the AlN were reduced to around 2.2×108 cm-2 and 1.3×109 cm-2 , respectively, using an optimized three-step process, as estimated by TEM. An atomically smooth surface with an RMS roughness of around 0.3 nm achieved over 5×5 µm 2 AFM scale. Furthermore, the motion of the steps in a one dimension model has been proposed to describe surface morphology evolution, especially the step bunching feature found under non-optimal conditions. In Chapter 5, control of alloy composition and the maintenance of compositional uniformity across a growing epilayer surface were demonstrated for the development of u-AlGaN epilayers. Optimized conditions (i.e. a high growth temperature of 1245 °C) produced uniform and smooth film with a low RMS roughness of around 2 nm achieved in 20×20 µm 2 AFM scan. The dopant that is most commonly used to obtain n-type conductivity in AlxGa1-xN is Si. However, the incorporation of Si has been found to increase the strain relaxation and promote unintentional incorporation of other impurities (O and C) during Si-doped AlGaN growth. In Chapter 6, reducing edge-type TDs is observed to be an effective appoach to improve the electric and optical properties of Si-doped AlGaN epilayers. In addition, the maximum electron concentration of 1.3×1019 cm-3 and 6.4×1018 cm-3 were achieved in Si-doped Al0.48Ga0.52N and Al0.6Ga0.4N epilayers as measured using Hall effect. Finally, in Chapter 7, studies on the growth of InAlN/AlGaN multiple quantum well (MQW) structures were performed, and exposing InAlN QW to a higher temperature during the ramp to the growth temperature of AlGaN barrier (around 1100 °C) will suffer a significant indium (In) desorption. To overcome this issue, quasi-two-tempeature (Q2T) technique was applied to protect InAlN QW. After optimization, an intense UV emission from MQWs has been observed in the UV spectral range from 320 to 350 nm measured by room temperature photoluminescence.

Flash-Sintering and Characterization of La0.8Sr0.2Ga0.8Mg0.2O3-δ Electrolytes for Solid Oxide Fuel Cells

La_0.8Sr_0.2Ga_0.8Mg_0.2O_3-δ (LSGM), a promising electrolyte material for intermediate temperature solid oxide fuel cells, can be sintered to a fully dense state by a flash-sintering technique. In this work, LSGM is sintered by the current-limiting flash-sintering process at 690°C under an electric field of 100 V cm^-1, in comparison with up to 1400°C or even higher temperature in conventional furnace sintering. The resultant LSGM samples are investigated by scanning electron microscopy, X-ray diffraction, and electrochemical impedance spectroscopy. The SEM images exhibit well-densified microstructures while XRD results show that the perovskite structure after flash-sintering does not changed. EIS results show that the conductivity of LSGM sintered by the current-limiting flash-sintering process increases with sintering current density value. The conductivity of samples sintered at 120 mA mm^-2 reaches 0.049 σ cm^-1 at 800°C, which is approximate to the value of conventional sintered LSGM samples at 1400°C. Additionally, the flash-sintering process is interpreted by Joule heating theory. Therefore, the current-limiting flash-sintering technique is proved to be an energy-efficient and eligible approach for the densification of LSGM and other materials requiring high sintering temperature.

I Stormens Öga : En kvalitativ studie inspirerad av grundad teori, om väntade förändringar inom elitidrottsföreningar

Adapt or die. En omvärld i ständig rörelse ställer högre krav än någonsin på organisationer att utveckla sitt förändringsarbete och sättet man ser på förändringar, något som lett till att fenomenet "organisationsförändringar" blivit ett fokusområde för organisationsforskare. Inom denna forskning framhävs inte sällan vikten av att ta ställning till hur anställda tar emot, och påverkas av, detta förändringsarbete. En typ av förändringar som dock förblivit outforskade är väntade förändringar, förändringar där de anställda vet att en förändring kan komma att ske men inte när eller hur den kommer ske. Inom idrotten återfinns en viss typ av organisationer, elitidrottsföreningar, som ställs inför väntade förändringar med jämna mellanrum. Dessa situationer uppkommer när föreningarna omplaceras i det standardiserade seriesystem som återfinns i Sverige och ställs inför kraftigt omväxlande ekonomiska förutsättningar. För att kunna hantera denna osäkerhet förutsätts att organisationen konstant står redo att genomföra omvälvande förändringar, enbart baserat på föreningens sportsliga resultat. Syftet med uppsatsen är att skapa en förståelse för de anställdas reaktioner vid situationer av omplacering och väntad förändring. För att uppnå syftet utgick uppsatsen ifrån bristen på forskning och sökte, med hjälp av metoden Grundad teori, producera en serie väl underbyggda frågeställningar baserade i studiens fynd. Frågeställningarna producerades sedan via fyra semi-strukturerade intervjuer inom två olika elitidrottsföreningar. Resultatet visar på att en utbredd acceptans för väntade förändringar återfinns hos anställda inom elitidrottsföreningar. Uppsatsens fynd grundades i data från respondenterna och sammanställdes via en resultatmodell innehållandes en kärnkategori och fyra underkategorier. Uppsatsen erbjuder således, via metodvalet, en nyproducerad infallsvinkel på en situation som många organisationer inom idrotten – men även utanför – kan komma att ställas inför.

Prevalência e Sintomatologia Associada a Doenças do Comportamento Alimentar em Adolescentes

As Doenças do Comportamento Alimentar apresentam-se como um problema de saúde proeminente e, como tal, devem ser entendidas como multidimensionais e complexas, que interagem com factores biológicos, psicológicos e sócio-culturais e, que podem ocorrer devido a comportamentos alimentares de carácter patológico e com consequências sérias na qualidade de vida presente e futura. Este trabalho de investigação teve como principal objectivo avaliar a prevalência das Doenças do Comportamento Alimentar numa população não clínica de estudantes, assim como caracterizar o perfil socio-demográfico e familiar dos estudantes e, determinar a relação entre a sintomatologia associada a perturbações do comportamento alimentar e o sexo, idade, IMC, tipo de família, vinculação aos pais e ano de escolaridade dos adolescentes. No intuito de concretizar os objectivos, realizámos um estudo não experimental, transversal e correlacional. A amostra foi constituída por 326 estudantes do 3º Ciclo e do Ensino Secundário da zona centro de Portugal. Foram aplicados um questionário anónimo composto por dados socio-demográficos, antropométricos e clínicos, o Eating Disorder Inventory 2 (EDI 2) e o Questionário de Vinculação ao Pai e à Mãe (QVPM). De acordo com os critérios presentes no DSM-IV-TR não encontramos qualquer caso de Bulimia Nervosa em ambos os sexos. Nas raparigas, constatamos 1,5% de casos prováveis de Anorexia Nervosa tipo Restritivo, 0% de casos prováveis de Anorexia Nervosa tipo Purgativa, 17,3% de casos prováveis de Anorexia Nervosa Restritiva Parcial e 6,1% de casos prováveis de Anorexia Nervosa Purgativa Parcial. Quanto aos rapazes, relatam-se 0,8% de casos prováveis de Anorexia Nervosa tipo Restritivo, 0% de casos prováveis de Anorexia Nervosa tipo Purgativa, 5,2% de situações parciais de Anorexia Nervosa Restritiva e 1,8% de situações parciais de Anorexia Nervosa Purgativa. Foram observadas também, correlações entre a sintomatologia associada a perturbações do comportamento alimentar consoante o sexo, idade, IMC, tipo de família, vinculação aos pais e ano de escolaridade dos inquiridos. Concluímos que todo o sistema familiar e escolar, especialmente pais e professores, devem estar alerta para os sinais manifestados pelos adolescentes no sentido de dar à prevenção um papel fulcral.

Comprendre et maîtriser le passage de type I à type II de puits quantiques d'In(x)Ga(1-x)As(y)Sb(1-y) sur substrat de GaSb

Les antimoniures sont des semi-conducteurs III-V prometteurs pour le développement de dispositifs optoélectroniques puisqu'ils ont une grande mobilité d'électrons, une large gamme spectrale d'émission ou de détection et offrent la possibilité de former des hétérostructures confinées dont la recombinaison est de type I, II ou III. Bien qu'il existe plusieurs publications sur la fabrication de dispositifs utilisant un alliage d'In(x)Ga(1-x)As(y)Sb(1-y) qui émet ou détecte à une certaine longueur d'onde, les détails, à savoir comment sont déterminés les compositions et surtout les alignements de bande, sont rarement explicites. Très peu d'études fondamentales sur l'incorporation d'indium et d'arsenic sous forme de tétramères lors de l'épitaxie par jets moléculaires existent, et les méthodes afin de déterminer l'alignement des bandes des binaires qui composent ces alliages donnent des résultats variables. Un modèle a été construit et a permis de prédire l'alignement des bandes énergétiques des alliages d'In(x)Ga(1-x)As(y)Sb(1-y) avec celles du GaSb pour l'ensemble des compositions possibles. Ce modèle tient compte des effets thermiques, des contraintes élastiques et peut aussi inclure le confinement pour des puits quantiques. De cette manière, il est possible de prédire la transition de type de recombinaison en fonction de la composition. Il est aussi montré que l'indium ségrègue en surface lors de la croissance par épitaxie par jets moléculaires d'In(x)Ga(1-x)Sb sur GaSb, ce qui avait déjà été observé pour ce type de matériau. Il est possible d'éliminer le gradient de composition à cette interface en mouillant la surface d'indium avant la croissance de l'alliage. L'épaisseur d'indium en surface dépend de la température et peut être évaluée par un modèle simple simulant la ségrégation. Dans le cas d'un puits quantique, il y aura une seconde interface GaSb sur In(x)Ga(1-x)Sb où l'indium de surface ira s'incorporer. La croissance de quelques monocouches de GaSb à basse température immédiatement après la croissance de l'alliage permet d'incorporer rapidement ces atomes d'indium et de garder la seconde interface abrupte. Lorsque la composition d'indium ne change plus dans la couche, cette composition correspond au rapport de flux d'atomes d'indium sur celui des éléments III. L'arsenic, dont la source fournit principalement des tétramères, ne s'incorpore pas de la même manière. Les tétramères occupent deux sites en surface et doivent interagir par paire afin de créer des dimères d'arsenic. Ces derniers pourront alors être incorporés dans l'alliage. Un modèle de cinétique de surface a été élaboré afin de rendre compte de la diminution d'incorporation d'arsenic en augmentant le rapport V/III pour une composition nominale d'arsenic fixe dans l'In(x)Ga(1-x)As(y)Sb(1-y). Ce résultat s'explique par le fait que les réactions de deuxième ordre dans la décomposition des tétramères d'arsenic ralentissent considérablement la réaction d'incorporation et permettent à l'antimoine d'occuper majoritairement la surface. Cette observation montre qu'il est préférable d'utiliser une source de dimères d'arsenic, plutôt que de tétramères, afin de mieux contrôler la composition d'arsenic dans la couche. Des puits quantiques d'In(x)Ga(1-x)As(y)Sb(1-y) sur GaSb ont été fabriqués et caractérisés optiquement afin d'observer le passage de recombinaison de type I à type II. Cependant, celui-ci n'a pas pu être observé puisque les spectres étaient dominés par un niveau énergétique dans le GaSb dont la source n'a pu être identifiée. Un problème dans la source de gallium pourrait être à l'origine de ce défaut et la résolution de ce problème est essentielle à la continuité de ces travaux.

O Serviço Social na Unidade de Transplantação Hepática Pediátrica e a Criação da Associação de Crianças e Jovens Transplantados ou com Doenças Hepáticas – HEPATURIX pelo Direito à Saúde

Com a crise financeira que se tem vindo a agudizar, com o agravamento da pobreza e exclusão social, associados a problemas de saúde e à emergência de problemas sociais (como o desemprego e a pobreza) tem assomado uma vaga de iniciativas de movimentos da sociedade civil. São novas formas de organização e resposta a situações específicas de grupos de indivíduos na luta por políticas públicas e direitos sociais tais como o da saúde, da habitação, da educação, do trabalho, entre outras. Nos finais da década de 70, em Portugal, a criação do Serviço Nacional de Saúde intenta o acesso à saúde garantido a todos os cidadãos. Nos anos 80 o Estado limita este direito baseado no princípio da justiça social protegendo os grupos mais desfavorecidos. Institui as taxas moderadoras e define as isenções para alguns doentes crónicos. Perante a desigualdade de direitos que daí advém, no Hospital Pediátrico de Coimbra, a partir dos anos 90, surgem movimentos associativos em prol dos direitos de saúde, criados e dinamizados por Assistentes Sociais, nomeadamente as Associações Acreditar em 1993, a Coração Feliz em 1994, a Associação Nacional de Fibrose Quística em 1996 e já no século XXI a Diabéticos Todo o Terreno em 2004 e a Hepaturix em 2006. A Hepaturix – Associação de Crianças e Jovens Transplantados ou com Doenças Hepáticas – fundada já no século XXI e cuja actividade será descrita neste trabalho, tem vindo a lutar pelos direitos sociais desta população, com a colaboração da Assistente Social que, no Hospital Pediátrico de Coimbra, apoia a Unidade de Transplantação Hepática Pediátrica. Entre outros, a isenção das taxas moderadoras para os doentes transplantados e para os dadores vivos assim como o direito aos transportes nas deslocações para o hospital após o transplante, são direitos sociais alcançados pela Hepaturix através da sensibilização do poder político. A Assistente Social tem sido um pilar neste percurso, sendo mediadora entre a instituição e a associação, em prol do direito destas crianças e jovens. / With the financial crisis that has been worsening, with increased poverty and social exclusion associated with health problems and the emergency of social problems (such as unemployment and poverty) there has been a loomed wave of initiatives for movements from the civil society. These are new ways of organization and response to specific situations of groups of individuals in the strike for public policies and social rights such as health, habitation, education, work, among others. In the late 70s, in Portugal, the creation of the National Health Service intents the access to health care guaranteed to all citizens. In the 80s the government limits this right based on the principle of social justice, protecting the most disadvantaged groups. Establishes user fees and defines the exemptions for some chronically ill. Before the inequality of rights resulted from this, there has been a rising of associative movements for health rights, created and dynamized by Social Workers at the Pediatric Hospital of Coimbra, from the 90s on: "Acreditar" in 1993, "Coração Feliz" in 1994, Associação Nacional da Fibrose Quistica" in 1996 and now, in the XXI century: "Diabéticos Todo o Terreno"in 2004 and "Hepaturix" in 2006. The “Hepaturix” - Association of Transplanted Children and Youth or with Hepatic Diseases - founded in the twenty-first century, whose will be discussed in this work, has been fighting for social rights of this population, with the cooperation of the Social Work who, at the Children’s Hospital of Coimbra, supports the Pediatric Hepatic Transplantation Unit. Among others, the exemption of user fees for transplanted patients and living donors as well as the right to transport at dislocations to the hospital after transplant, are social rights accomplished by Hepaturix, through the awareness of political power. The Social Worker has been a pillar in this journey, being a mediator between the institution and the association on behalf of the rights of these children and youth.

Matematik i det mångkulturella klassrummet : En litteraturstudie om flerspråkiga elevers problemlösningsförmåga

Forskning visar att flerspråkiga elevers matematikresultat sjunker i takt med att antalet flerspråkiga elever ökar i klassrummen. Forskningsresultaten visar att flerspråkiga elever framförallt har svårt för problemlösningsuppgifter med mycket text. Frågan är om lärare har tillräckligt med kunskaper och resurser för att tillgodose alla elevers behov. Syftet med vår litteraturstudie är att undersöka vilka strategier lärare kan använda för att stödja flerspråkiga elever. Vidare tar litteraturstudien upp vad som är betydelsefullt för att flerspråkiga elever ska kunna utveckla sin problemlösningsförmåga. I denna litteraturstudie har vetenskapligt granskade texter sökts och upptäckts via användning av olika söktekniker och därefter analyserats. Sökmetoderna vi har använt är slumpmässig sökning, systematisk sökning och kedjesökning. I litteraturstudien förekommer avhandlingar, konferensbidrag, empiriska undersökningar och artiklar i vetenskapligt granskade tidskrifter. Resultatet av vår litteraturstudie visar att flerspråkiga elever påverkas av flera olika faktorer. Lärare har en betydande roll för att eleverna ska kunna utveckla problemlösningsförmågan i ämnet matematik. Vårt resultat tar upp aspekter som lärare i ett mångkulturellt klassrum bör ta hänsyn till i undervisningen. De aspekter som tas upp i litteraturstudien är huruvida lärare tar hänsyn till elevernas tidigare erfarenheter och deras kultur. Ett viktigt begrepp inom detta område som behandlas i litteraturstudien är det etnomatematiska perspektivet. Vidare visar litteraturstudiens resultat att de flerspråkiga elevernas tillgång till sitt modersmål är en väsentlig del för att utveckla matematiska färdigheter. Fortsättningsvis visar resultatet att lärares val av kontextanknutna uppgifter är avgörande för att flerspråkiga elever ska kunna se en helhet i matematiska textuppgifter. Slutligen visar resultatet att det är viktigt att flerspråkiga elever måste ges möjlighet att tala matematik och att lärare belyser viktiga matematiska begrepp i klassrummet. 

As doenças infeciosas e a história dos antibióticos

O presente trabalho aborda a história das principais doenças que assolaram a Europa desde a época medieval à época contemporânea, incluindo a referência às origens, às manifestações e ao tratamento. É igualmente abordada a questão do isolamento das substâncias ativas nas plantas medicinais e farmacológicas até à descoberta do primeiro antibiótico identificado pelo homem – a penicilina, por Alexandre Fleming – e a sua enorme importância no combate aos micro-organismos.

A fisioterapia no controle e prevenção da disseminação e transmissão das doenças infecciosas

O fisioterapeuta, enquanto profissional de saúde, contacta com uma elevada heterogeneidade de utentes e ambientes e caso sejam negligenciadas as corretas medidas de prevenção e controlo da transmissão e disseminação de doenças infecciosas, o próprio fisioterapeuta além de colocar a sua própria segurança em risco, poderá tornar-se um veículo para a transmissão e disseminação das mesmas entre pacientes, entre pacientes e fisioterapeuta, outros profissionais de saúde e, concomitantemente, levar à contaminação do ambiente e comunidade em geral. Deste modo, é pertinente e urgente que o fisioterapeuta, enquanto profissional de saúde, seja portador de conhecimento sobre os princípios que compreendem as doenças infecciosas e a sua disseminação e as medidas adequadas para o seu controlo e prevenção, de forma a poder contribuir para a prevenção e controlo da infecção como elemento essencial na sua prática profissional.
