Språkstimuleringens betydelse i förskolan för senare läs- och skrivinlärning

Skyllkvist, Susanne, Israelsson, Anna January 2007 (has links)
<p>Examensarbetets syfte är att belysa och analysera hur pedagoger arbetar med språkstimulering i förskolan. Vi presenterar vad tidigare forskning inom området språkstimulering belyser som viktigt vid barnens tidiga språk och skriftmöte. Om barnen får chansen att på ett utvecklande sätt delta i rim och ramsor samt samtala om texter har de, enligt forskningen, en större chans att lära sig läsa och skriva. Genom att genomföra kvalitativa intervjuer med fyra pedagoger har vi undersökt hur förskolan förhåller sig gentemot rådande forskning kring språk-stimulering. Vi kommer att redovisa hur respondenterna redogör för hur de arbetar med språkstimulering i verksamheten och vilka metoder pedagogerna berättar att de arbetar utifrån. Resultatet av våra intervjuer är att tre av de fyra pedagogerna i förskolan inte utformar verksamheten utifrån forskningsresultat. Intervjuerna visar också att pedagogerna arbetar mycket kring rim och ramsor, men att någon speciell metodmedvetenhet inte finns hos tre av pedagogerna. I analysen plockar vi fram de likheter och skillnader mellan forskningen och respondenternas utsagor som vi anser är av betydelse för studien. Pedagogernas arbetssätt placerar vi in i utvecklingsnivåer för att visa om och hur arbetssätten följer och främjar barnens språkliga utveckling. I diskussionen tar vi upp hur det tidiga skriftspråksmötet ser ut i verksamheten. Vi diskuterar även varför högläsning och bearbetning av texter inte har så stor del i verksamheten, trots att det enligt flera forskare har en avgörande betydelse när barnen ska lära sig läsa och skriva. I diskussionen kommer vi fram till att de flesta pedagogerna arbetar utifrån en ”tyst kunskap”.</p>

A Study On Values, Problems And Potentials Of The Traditional Dwellings In Karabaglar-mugla

Timur, Baris Ali 01 March 2012 (has links) (PDF)
Karabaglar district of Mugla, which was registered as a conservation site in 1977, is a low density traditional settlement which has had a family scale agricultural production background. Most of the families, living in the town center, used to migrate to their houses and their farms in that fertile district from the spring till the autumn in order to prepare their needs of foods for the winters as the production of family scale agriculture and animal husbandry. Today the district is located next to Mugla University campus in K&ouml / tekli district in the south and neighbors the axis relating university to the city center in the west. The land values in Karabaglar are very high because the area has always been a prestige zone for the citizens of Mugla because of its cultural and traditional background and the natural beauty. Unfortunately these characteristics lead either to rapid and unconscious restoration interventions or to the total abandoning of the traditional buildings to collapse in order to use the land in future. Therefore / Karabaglar is in danger of losing its traditional, urban, architectural and natural characteristics. This study seeks to fulfill the already made urban-scaled conservation studies with the architectural-scaled data. It aims to determine the values, problems and potentials of the traditional dwellings in Karabaglar-Mugla.

Impacts of protected areas on adjacent communities: an examination of attitudes and perceptions towards Pacific Rim National Park Reserve.

Chafey, Adam 04 May 2012 (has links)
Protected areas, such as national parks, can provide nearby communities with a wide range of environmental, social, and economic benefits, such as ecosystem services and tourism development. However, protected areas can also subject communities to a number of costs, such as displacement and an increase in negative human-wildlife interactions. This study investigates how the communities of Tofino and Ucluelet, British Columbia, Canada perceive they have been impacted by Pacific Rim National Park Reserve (PRNPR). Specific areas of focus include respondents’ attitude and level of support for PRNPR and their perceptions of concerns and benefits related to the park. Data for this study was collected using a focus group and questionnaire administered using the “drop-off” method. The results of this study suggest that residents of Tofino and Ucluelet generally have a positive attitude towards the park and perceive PRNPR subjects their communities to a number of concerns and benefits. It was found that attitudes were linked to perceived concerns and benefits, perceived changes in the community, and level of involvement with PRNPR. With regards to concerns and benefits, it was found that respondents were most concerned with financial costs related to PRNPR and most valued benefits related to conservation. / Graduate

Lek med språkljud. : En studie om hur förskolepedagoger inom tre pedagogiska inriktningar arbetar med språklekar kring fonologisk medvetenhet. / Work with Speech Sounds. : A study of how Preschool Teachers in Different Educational Approaches Work with Speech Sounds to Achieve Phonological Awareness.

Åsberg, Katarina, Ohlsson, Anna-Stina January 2014 (has links)
Föreliggande examensarbete bygger på en enkätundersökning bland pedagoger som är verksamma inom förskolor med olika pedagogiska inriktningar i två kommuner. De tre inriktningarna representeras av förskolepedagoger, som enbart arbetar utifrån förskolans läroplan, Montessorilärare samt pedagoger som arbetar utifrån Reggio Emiliafilosofin. Vår undersökning visar att en hel del lärare, som är verksamma inom samtliga inriktningar, framför allt arbetar med såväl planerade som spontana språklekar som rör rim, ramsor samt stavelser. Färre pedagoger arbetar med språklekar som rör enskilda språkljud i ord, vilket är mer abstrakt och kommer senare i utvecklingen av den fonologiska medvetenheten.  Vid en jämförelse mellan de olika inriktningarna kan vi skönja, att flest Montessorilärare arbetar med språklekar som rör språkljud på förskolorna. Färst pedagoger som arbetar med dessa lekar är verksamma på de förskolor, där lärarna arbetar utifrån Reggio Emiliafilosofin.

Efeitos da rosuvastatina e da atividade física de baixa intensidade na morfologia renal de ratos normotensos e espontaneamente hipertensos (SHR) / Effects of the rosuvastatin and low intensity physical activity on the morphology of kidney from normotensive and spontaneously hypertensive rats (SHR)

Angelica Beatriz Garcia Pinto 30 September 2011 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Desordens do sistema renal podem ser as causas da hipertensão arterial, a qual pode, por sua vez, causar doenças renais. A pressão sanguínea elevada é muito comum também nas doenças crônicas dos rins, e é, além disso, um conhecido fator de risco para uma mais rápida progressão da falha renal. A incidência de doenças renais crônicas está aumentando no mundo, e há uma grande necessidade de identificar as terapias capazes de deter ou reduzir a progressão da doença. Há crescente evidência de que as estatinas poderiam desempenhar um papel terapêutico. Além disso, tem sido demonstrado que a atividade física melhora a função renal em pacientes. Estudos ultra-estruturais em humanos e em ratos demonstraram a presença de junções gap dentro de todas as células do glomérulo e os podócitos demonstraram conter principalmente conexina-43 (Cx-43). O presente estudo tem como objetivo observar os efeitos da rosuvastatina e da atividade física de baixa intensidade na estrutura e ultra-estrutura renal e na expressão glomerular de Cx-43 em ratos normotensos (WKY) e em ratos espontaneamente hipertensos (SHR). Os ratos foram divididos aleatoriamente em oito grupos: WKY-C: animais normotensos que não receberam rosuvastatina; WKY-ROS: animais normotensos que receberam rosuvastatina 20mg/kg/dia por gavagem orogástrica; SHR-C: animais hipertensos que não receberam rosuvastatina; SHR-ROS: animais hipertensos que receberam rosuvastatina, como descrito no grupo WKY-ROS; SED-WKY: animais normotensos sedentários; EX-WKY: animais normotensos exercitados; SED-SHR: animais hipertensos sedentários; e, EX-SHR: animais hipertensos exercitados. Os animais dos grupos SHR-C, SHR-ROS e SED-SHR apresentaram níveis de pressão arterial maiores que os animais dos grupos WKY-C, WKY-ROS, SED-WKY, EX-WKY e EX-SHR. A massa corporal dos grupos de animais não diferiram significativamente durante o experimento. Não houve diferença nos níveis sanguíneos de uréia, creatinina, ácido úrico e creatinafosfoquinase entre os animas dos grupos estudados. No entanto, houve um aumento da excreção de proteína de 24 horas nos animais do grupo SHR-C. Houve um aumento na área capsular nos animais do grupo SHR-C. Por microscopia eletrônica de transmissão observou-se que nos animais SHR-C e SED-SHR a barreira de filtração glomerular, o diafragma de fenda e os podócitos estão alterados exibindo os vacúolos nos podócitos e pedicelos mais curtos e mais espessos. Por microscopia eletrônica de varredura, os animais SHR-C e SED-SHR exibiram pedicelos mais afilados, curtos e tortuosos. Um aumento da imunofluorescência para Cx-43 foi observada em células epiteliais viscerais dos glomérulos dos animais do grupo WKY-ROS e nas células parietais e viscerais dos glomérulos dos animais do grupo SHR-ROS, se comparado com os grupos WKY-C e SHR-C. Por outro lado, os animais dos grupos SED-SHR e EX-SHR exibiram diminuição da expressão de Cx-43, comparados aos animais SED-WKY e EX-WKY. Em conclusão, podemos supor que os efeitos renais da rosuvastatina e da atividade física de baixa intensidade podem ser ferramentas terapêuticas para melhorar a estrutura e conseqüentemente a função renal em indivíduos hipertensos / Disorders of the renal system may be the cause of hypertension, which can in turn cause kidney disease. The high blood pressure is also very common in chronic kidney diseases, and is also a known risk factor for faster progression of renal failure. The incidence of chronic kidney disease is increasing worldwide, and there is a great need to identify therapies to stop or slow the progression of the disease. There is growing evidence that statins could play a therapeutic role. Moreover, it has been shown that physical activity improves renal function in patients. Ultrastructural studies in humans and rats have shown the presence of gap junctions in all cells of the glomerular podocytes and also to contain mainly connexin-43 (Cx-43). This study aims to observe the effects of rosuvastatin and low-intensity physical activity on the structure and ultrastructure of kidney and glomerular expression of Cx-43 in normotensive rats (WKY) and spontaneously hypertensive rats (SHR). The rats were randomly divided into eight groups: WKY-C: normotensive animals not receiving rosuvastatin, WKY-ROS: normotensive animals that received rosuvastatin 20mg/kg/day by orogastric gavage, C-SHR: hypertensive animals not receiving rosuvastatin; SHR -ROS: hypertensive rats that received rosuvastatin, as described in ROS-WKY group, WKY-SED: sedentary normotensive, WKY-EX: normotensive rats exercised, SHR-SED: sedentary hypertensive rats, and EX-SHR: hypertensive rats exercised . The animals in groups C-SHR, SHR-SED and SHR-ROS had blood pressure levels higher than the animals in groups WKY-C, ROS-WKY, WKY-SED, EX-SHR and EX-WKY. The body mass of groups of animals did not differ significantly during the experiment. There was no difference in urea, creatinine, uric acid and creatine phosphokinase blood levels among animals of the studied groups. However, there was an increased excretion of 24 hours protein in SHR-C group. There was an increase in the capsule in group SHR-C. Transmission electron microscopy showed that in SHR-C and SED-SHR glomerular filtration barrier, the slit diaphragm and podocyte were altered. By scanning electron microscopy, the C-SHR and SED-SHR animals exhibited thinner, shorter and more tortuous pedicels. An increase in immunofluorescence for Cx-43 was observed in visceral epithelial cells of the glomeruli of group and in WKY-ROS and in visceral and parietal cells of the glomeruli of SHR-ROS group, compared with WKY-C and SHR- C. On the other hand, SHR-SED and EX-SHR animals exhibited decreased expression of Cx-43 compared with WKY-SED and EX-WKY animals. In conclusion, we can assume that the renal effects of rosuvastatin and low-intensity physical activity can be therapeutic tools to improve the structure and consequently renal function in hypertensive subjects

Legatti, Sabrina Almeida Moreira January 2017 (has links)
Orientador: Antonio Carlos Paes / Resumo: Introdução: Os números relacionados à letalidade na lesão renal aguda (LRA) em cães e gatos de acordo com a etiologia são pouco conhecidas. Este é o primeiro estudo que avaliou as evidências disponíveis sobre a LRA para ajudar na tomada de decisões na prática clínica. Objetivos: Avaliar a letalidade da LRA em cães e gatos de acordo com a etiologia, infecciosa ou não infecciosa, e também em cães e gatos que estavam recebendo tratamento dialítico ou conservador. Métodos: Pesquisas em Medline, EMBASE e LILACS até julho de 2016 e revisão de listas de referências dos trabalhos incluídos. Os critérios de inclusão foram estudos em série de casos que avaliaram o tratamento de dialítico ou conservativo em cães e gatos com LRA independentemente da etiologia e letalidade por todas as causas relatada. A proporção agrupada e o intervalo de confiança (IC) são apresentados para cada resultado. A significância estatística foi definida com a não sobreposição dos intervalos de confiança de 95%, obtidos para cada intervenção. Resultados: Dezenove séries de casos envolvendo 1.233 animais foram elegíveis. As proporções agrupadas para a letalidade global, independentemente do tratamento e da etiologia, foram: gatos 52,6% e cães 45,0%. Os valores de letalidade de acordo com o tratamento foram numericamente maiores nos cães e gatos que receberam diálise quando comparado com o tratamento conservador. As diferenças significativas foram observadas devido à não-sobreposição das IC 95%, mostrando maiores...

This is the first study that evaluated the available evidence on AKI to allow decision-making in clinical practice. Objectives: To evaluate the lethality rate in cats and dogs with AKI accordingly to the etiology (i.e. infectious versus non-infectious), and the incidence of lethality in cats and dogs that were receiving either dialytic or conservative treatment. Methods: Searches of Medline, EMBASE, and LILACS to July 2016 and review of reference lists of previous review. Inclusion criteria were case series studies evaluating dialytic or conservative treatment in cats and dogs with AKI, regardless the etiology and all-cause lethality reported. The pooled proportion and the confidence interval (CI) are shown for each outcome. Statistical significance was defined if the 95% confidence intervals obtained for each intervention did not overlap. Results: 19 case series involving 1,233 animals proved eligible. The pooled proportions for overall lethality regardless the treatment and etiology were: cats 52.6% and dogs 45.0%.The rates of lethality accordingly the treatment were higher in the cats and dogs that receiving dialysis, regardless the etiology when comparing with conservative treatment, however there was no significant difference. Effect differences were seen due to the non-overlap of the 95% CIs showing higher proportions of mortality in AKI ... (Complete abstract click electronic access below) / Doutor

Transplante renal em crianças com peso inferior a 15 kg : acesso cirúrgico extraperitoneal: experiência em 62 transplantes

Vitola, Santo Pascual January 2011 (has links)
Crianças pequenas representam um grupo desafiador no transplante renal. O estudo analisa os resultados, do ponto de vista cirúrgico, do transplante renal em crianças com peso inferior a 15 kg utilizando o acesso cirúrgico extraperitoneal. Métodos: Foram revisados retrospectivamente os prontuários de 62 crianças com peso inferior a 15 kg submetidas a transplante renal entre 1998 e 2010, utilizando o acesso extraperitoneal e anastomose dos vasos renais dos doadores com a aorta ou artéria ilíaca comum e com a veia cava inferior ou ilíaca comum dos receptores. O ureter foi anastomosado à bexiga pela técnica extravesical de Lich- Grégoir. Resultados: Dos 62 transplantes, 32 enxertos (51,6%) eram provenientes de doadores vivos e 30 (48,4%) de doadores falecidos, sendo 28 deles pediátricos. A média de idade no transplante foi de 3,7 ± 2,2 anos (1 a 12), e o peso médio, de 12,3 ± 2,1 kg (5,6 a 14,9), sendo que 10 tinham peso inferior a 10 kg. Em 10 crianças (16,1%) o transplante foi preemptivo e em 5 (8,1%) havia trombose do sistema venoso prévio ao transplante. Em 1 e 5 anos, a sobrevida do paciente foi de 93,2% e 84,2% e a sobrevida do enxerto de 85,2% e 72,7%, respectivamente, sem diferença entre doadores vivos e falecidos. A função do enxerto com doador vivo foi melhor em 1 e 3 meses, mas a partir do 6o mês foi similar. Houve 6 complicações vasculares, sendo 4 tromboses vasculares, 1 laceração e 1 estenose de artéria renal e 2 coleções líquidas. Houve 17 perdas de enxerto, 6 por morte, sendo 5 com enxerto funcionante, 5 por complicações cirúrgicas, 3 por rejeição crônica e 3 por recorrência da doença de base. Conclusão: O acesso extraperitoneal é uma técnica válida no transplante renal de crianças com peso inferior a 15 kg, assegurando boa sobrevida do paciente e do enxerto e aceitável taxa de complicações, independentemente do tipo de doador, se vivo ou falecido, ou do tamanho do enxerto, se de adulto ou de criança. / Small children are a challenging group for kidney transplantation. This study analyzes the results of kidney transplantation in children weighing less than 15 kg using the extraperitoneal surgical access. Methods: A retrospective review of the records of 62 children weighting less than 15 kg was done. The kidney transplantation were performed between 1998 and 2010 using the extraperitoneal access and anastomosis of the renal vessels of donors to the aorta or common iliac artery and to the inferior vena cava or common iliac vein of the recipients. The ureter was anastomosed to the bladder using the Lich-Grégoir extravesical technique. Results: Thirty-two (51.6%) grafts of the 62 transplants were from living donors and 30 (48.4%) from deceased donors, 28 of them pediatric. The mean age at transplantion was 3.7 ± 2.2 years (1 to 12), and the mean weight, 12.3 ± 2.1 kg (5.6 to 14.9), and 10 of them weighed less than 10 kg. In 10 children (16.1%) the transplant was preemptive. Five 5 (8.1%) children presented previous thrombosis of the venous system. At 1 and 5 years, patient survival was 93.2% and 84.2% and graft survival was 85.2% and 72.7%, respectively, and there was no difference between living and deceased donors. The graft function of the living donor was better at 1 and 3 months, but was similar from the 6th month onward. There were 6 vascular complications (4 of them vascular thromboses, 1 laceration and 1 renal artery stenosis) and 2 perirenal collections. Seventeen grafts were lost, 6 due to death, 5 with a functioning graft, 5 due to surgical complications, 3 due to chronic rejection and 3 due to recurrence of the original disease. Conclusion: The extraperitoneal access is a valid kidney transplantantion technique in children weighing less than 15 kg, ensuring good patient and graft survival, and an acceptable rate of complications, independent of source of donor, living or deceased, or size of graft, whether from an adult or from a child.
