Riskfaktorer för postoperativ sårinfektion

Postoperativa infektioner är ett utbrett problem inte bara i Sverige utan även runt om i världen och skapar lidande för patienten och stora kostnader för landets landsting och kommuner. Idag klassas postoperativa infektioner i Sverige som den tredje största gruppen av vårdrelaterade infektioner. Hälso- och sjukvårdspersonalens insatser är av stor vikt när vi idag har fått en ökad medvetenhet om att postoperativa sårinfektioner kan förebyggas och på så sätt uppnå kraven på en god vård. Syftet med denna studie var att identifiera vilka riskfaktorer som finns vid postoperativa sårinfektioner. Examensarbetet är en litteraturstudie och genom analysering och kvalitetsgranskning av 23 vetenskapliga artiklar framkom i resultatet fyra huvudområden och nio underområden. De fyra huvudområdena beskriver riskfaktorer vid pre- per- och postoperativ vård samt bristen på följsamhet till riktlinjer som riskfaktor. De nio underområdena som framkom var preoperativ dusch och lokal hudförberedelse, nutritionsstatus, personalens händer, hypotermi, operationstid, operationsmiljö, sårvårdsmetod, förband och följsamhet till riktlinjer. Ett resultat var att patienten med hjälp av information och instruktioner från vårdpersonalen i den preoperativa fasen kan bidra till att minimera risken för att utveckla postoperativ sårinfektion. Det är viktigt att vårdpersonalen följer de riktlinjer som finns för att minska risken för postoperativa sårinfektioner. För att följsamheten till riktlinjerna ska öka krävs att vårdpersonalen är medveten om vilka riskfaktorerna är och hur de kan påverka uppkomsten av postoperativa infektioner. Denna studie kan användas som ett hjälpmedel vid planering av hälso- och sjukvårdspersonalens arbetsrutiner och utformande av preoperativ, peroperativ och postoperativ vård i betydelsen av ett

Undersökande arbetssätt i NO-undervisningen i grundskolans tidigare årskurser

This thesis deals with the use of inquiry-based approaches in primary school science. The aim is to investigate the goals and purposes that are constituted by the curriculum and by the teachers in interviews and through their teaching in the classroom. The results are used to develop conceptual tools that can be used by teachers’ in their work to support students’ learning of science when using an inquiry-based approach. The thesis is comprised of four papers. In paper one a comparative analysis is made of five Swedish national curricula for compulsory school regarding what students should learn about scientific inquiry. In paper two 20 teachers were interviewed about their own teaching using inquiry. Classroom interactions were filmed and analyzed in papers three and four, which examine how primary teachers use the various activities and purposes of the inquiry classroom to support learning progressions in science. The results of paper one show how the emphasis within and between the two goals of learning to carry out investigations and learning about the nature of science shifted and changed over time in the different curricula. Paper two describes the selective traditions and qualities that were emphasized in the teachers’ accounts of their own teaching. The results of papers three and four show how students need to be involved in the proximate and ultimate purposes of the teaching activities for progression to happen. The ultimate purposes are the scientific purposes for the lesson (as given by the teacher or by the curriculum), whereas the proximate purposes are the more student-centered purposes that through different activities should allow the students to relate their own experiences and language to the ultimate purpose. The results show the importance of proximate purposes working as ends-in-viewin the sense of John Dewey, meaning that the students see the goal of the activity and that they are able to relate to their experiences and familiar language.

Vad ska elever lära sig angående naturvetenskaplig verksamhet? : En analys av svenska läroplaner för grundskolan under 50 år

The purpose of this study is to contribute to an understanding of which changes related to scientific inquiry have been made historically in curriculum documents. A comparative analysis is made of five Swedish national curricula– Lgr 62, Lgr 69, Lgr 80, Lpo 94 and Lgr 11 – during the last 50 years regarding what compulsory school students (school years 1–9) should learn about scientific inquiry. It focuses 1) what students should learn about carrying out scientific inquiries, and 2) what students should learn about the nature of science. All of the curricula examined have aims concerning scientific inquiry. The results show that during the period there have been many shifts in emphasis and changes of aims, for example from learning an inductive method to a more deductive one, and from an emphasis on carrying out investigations to an emphasis on more conceptual understanding of scientific investigations. Because teaching traditions tend to conserve aspects of earlier curricula, it is discussed how the results can help teachers, teacher students and curriculum developers to better see the consequences of the changes for teaching and learning.

Selektiva traditioner i grundskolans tidigare år : Lärares olika betoningar av kvalitéer i NO-undervisningen

The aim of this study was to elucidate the selective traditions of Swedish primary school teachers in using inquiry-based learning.  Material from thirteen interviews where teachers described their own inquiry practice was used to study the selective traditions along with the qualities these traditions emphasized. Four different selective traditions were identified: the fact oriented, the activity oriented, the collaboration oriented and the community oriented traditions. Different qualities were emphasized in the different traditions, for instance regarding whether teaching and inquiry should be difficult, correct, free or fun.

Arbetsprocesser i scenkonstnärliga projekt : En kvalitativ studie på videoscenografer verksamma inom opera

Syftet med denna kvalitativa undersökning är att bidra med kunskap om hur scenografiska projekt organiseras, i första hand inom operakonsten. Resultatet är användbart för forskning inom organisation samt användbart för branschen. Huvudfrågan är: hur ser arbetsprocessen ut för konstnärliga projektgrupper verksamma inom operakonst? Delfrågorna är: vilka faktorer påverkar vilka kriterium videoscenografer har för skapande? Vilka faktorer är viktigast för gott styrande av konstnärliga projektgrupper verksamma inom operakonst? Analysprocessen består av sammankopplingar mellan respondenternas svar och Pierre Bourdieus teorier om det kulturproducerande fältet samt jämförelse med tidigare forskning. Intervjuer med tre videoscenografer har legat till grund för analysen om hur vi organiserar oss i konstnärliga projekt på operascenen. Resultatet av den kvalitativa undersökningen är att den verksammes bakgrund, intressen och utbildning har påverkan på de arbetsmässiga val som tas. Ett gott ledarskap av en konstnärlig grupp som skapar videoscenografi innebär att visa på tydlighet och respekt till alla medarbetare. Diskussionen handlar om studiens styrkor, svagheter och förslag till fortsatt forskning. Styrkan i undersökningen är respondenternas karakteristiska svar som med tydlighet kunde förklaras med hjälp av Bourdieus teorier samt tidigare forskning. Svagheten i undersökningen är att den endast byggs på den empiri som samlats in genom intervjuer. Förslag till fortsatt forskning är således att undersöka om samma resultat kan erhållas med en annan metod.

Analysis Of Semi-Distributed And Global Hydrological Models In The Central Tropical Basins Of The Gulf Of Mexico To The Effects Of Extreme Hydrometeorological Phenomena

In the last years extreme hydrometeorological phenomena have increased in number and intensity affecting the inhabitants of various regions, an example of these effects are the central basins of the Gulf of Mexico (CBGM) that they have been affected by 55.2% with floods and especially the state of Veracruz (1999-2013), leaving economic, social and environmental losses. Mexico currently lacks sufficient hydrological studies for the measurement of volumes in rivers, since is convenient to create a hydrological model (HM) suited to the quality and quantity of the geographic and climatic information that is reliable and affordable. Therefore this research compares the semi-distributed hydrological model (SHM) and the global hydrological model (GHM), with respect to the volumes of runoff and achieve to predict flood areas, furthermore, were analyzed extreme hydrometeorological phenomena in the CBGM, by modeling the Hydrologic Modeling System (HEC-HMS) which is a SHM and the Modèle Hydrologique Simplifié à I'Extrême (MOHYSE) which is a GHM, to evaluate the results and compare which model is suitable for tropical conditions to propose public policies for integrated basins management and flood prevention. Thus it was determined the temporal and spatial framework of the analyzed basins according to hurricanes and floods. It were developed the SHM and GHM models, which were calibrated, validated and compared the results to identify the sensitivity to the real model. It was concluded that both models conform to tropical conditions of the CBGM, having MOHYSE further approximation to the real model. Worth mentioning that in Mexico there is not enough information, besides there are no records of MOHYSE use in Mexico, so it can be a useful tool for determining runoff volumes. Finally, with the SHM and the GHM were generated climate change scenarios to develop risk studies creating a risk map for urban planning, agro-hydrological and territorial organization.

Primeiro registro de teiidae (squamata, lacertilia) para o pleistoceno superior do estado do Rio Grande do Sul, Brasil

Este trabalho trata do primeiro Squamata (Lacertilia, Teiidae) do Pleistoceno superior do Estado do Rio Grande do Sul, Brasil, e atribuído ao gênero Tupinambis. O material (MCN-PV 2184) é uma hemimandíbula direita, basicrânio, três vértebras dorsais, rádio e ulna esquerdos de um mesmo indivíduo, e provém da Formação Touro Passo, cujos répteis eram antes representados apenas por Testudines. O espécime apresenta as sinapomorfias dos Teiidae e muitas características das espécies recentes de Tupinambis, mas dintingue-se pelo maior tamanho e pelos seguintes caracteres: tubérculo basal mais horizontalizado, dentário e esplenial muito altos, coronóide relativamente baixo, articular com margem ventral marcadamente côncava, e crista adutora muito proeminente, pelo que a face lateral do articular está voltada látero-ventralmente.

A apostasia comunista: a subjetividade como política

Edgard Morin (Auto-critique), Annie Kriegel (Ce que j'ai cru comprendre) e Claude Roy (Moi, je) percorrem passo a passo, desde a infância, as trilhas que o levaram ao PCF; os três participaram da resistência anti-nazista ao lado da União Soviética, ocasião da entrada em comunismo. Seguem-se as descrições de uma lenta asfixia moral em que os depoimentos fazem perceber como a rede das necessidades internas à subjetividade. Este artigo, analisando as autobiografias de três intelectuais franceses no momento em que dão criticamente conta de seu passado comunista procura apreender a figura histórica toda negativa da relação a si nas assim chamadas contra-sociedades comunistas durante o período stalinista.

Phylogenetic analysis of flatfish (order pleuronectiformes) based on mitochondrial 16s rDNA sequences

The phylogenetic relationships of the order Pleuronectiformes are controversial and at some crucial points remain unresolved. To date most phylogenetic studies on this order have been based on morpho-anatomical criteria, whereas only a few sequence comparisons based studies have been reported. In the present study, the phylogenetic relationships of 30 flatfish species pertaining to seven different families were examined by sequence analysis of the first half of the 16S mitochondrial DNA gene. The results obtained did not support percoids as the sister group of pleuronectiforms. The monophyletic origin of most families analyzed, Soleidae, Scophthalmidae, Achiridae, Pleuronectidae and Bothidae, was strongly supported, except for Paralichthyidae which was clearly subdivided into two groups, one of them associated with high confidence to Pleuronectidae. The analysis of the 16S rRNA gene also suggested the monophyly of Pleuronectiforms as the most probable hypothesis and consistently supported some major interfamily groupings.

Estudo da viscosidade do sangue: quantidade de amostra necessária à obtenção de medida

Os valores encontrados para a viscosidade sanguínea tendem a aparecer com diferenças significativas, de acordo com o sexo, avançar da idade e uso de substâncias. Pelo fato de o sangue ser um fluido não newtoniano, não podemos expressar sua viscosidade em termos absolutos sem que sejam levadas em conta as condições em que a mensuração é feita. Estudos anteriores destacaram a importância esta medida, considerando o efeito da idade, o uso de substâncias, bem como sua relação com Fluxo Sanguíneo Regional Cerebral, o que pode indicar correlação com declínios cognitivos. Entretanto, a prática médica carece ainda de um método simples e clinicamente prático para a verificação desta medida, além de valores de referência. Como passo inicial no sentido de padronizar os procedimentos e condições do processo de medição, avaliamos a quantidade mínima de amostra necessária para a medição da viscosidade sanguínea, utilizando este equipamento. Um total de 20 amostras de sangue foram coletadas de indivíduos saudáveis, entre 18 e 60 anos, em tubos com EDTA, e cada amostra dividida em 9 sub-amostras (de 600μl, 550μl, 500μl, 450μl, 400μl, 350μl, 300μl, 250μl e 200μl), totalizando, portanto, um total de aproximadamente 180 medições. A quantidade de 200 μl apresentou diferenças significativas com relação à primeira medida obtida, quando comparada com todas as demais quantidades (p<0,001), o que indica que com o uso desta quantidade, não é possível obter resultados confiáveis, pois existe alteração nos valores de VS obtidos relacionada à quantidade de material utilizado. Considerando a menor quantidade, bem como, que estivesse dentro da faixa de variação aceitável de 0,2 mPa.s, e a qual não apresentasse diferença significativa quando comparadas às demais (p>0,05), foi verificada a quantidade de 250 μl como a mais eficiente...
