Objectives: Serra da Estrela native (SEN) breed of sheep is one of the most important in Portugal, standing responsible for the production of one of the most internationally recognized cheeses in the world, "Queijo Serra da Estrela” (protected designation of origin). One of the major risks to the sustainability of SEN dairy flocks if footrot, an infectious diseases that causes lameness, decrease in milk production, weight loss and decrease in fertility. The aim of this work was to determine which parameters become decisive for the appearance of footrot in SEN dairy flocks, while establishing associations with environmental and nutritional variables. Materials and Methods: The present study was carried out by performing an especially designed 27 multiple choice questionnaire, based on the underlying causes of lameness in livestock and in the clinical diagnosis performed by the vet techinichian of the clinical cases evaluated at the moment of the inquiry. The survey was performed during the execution of the oficial veterinary health program between February and September of 2014 by a veterinarian team from the Association of SEN Sheep Breeders (ANCOSE). The ovine producers (N=30, with a total of 1270 animals) were randomly selected from the extense area of production of “Queijo Serra da Estrela”. The parameters evaluated in the study were: season and consequent weather changes during the period of the study, floor types, hygiene conditions, bed types, the existence and use of footbaths, location of footbaths, foot trimming and foot hygiene procedures. After the construction of the database and using the Statistical Package for Social Sciences version 16.0 the frequency response for each item was calculated. Results: All SEN livestock producers are proactive in the treatment of lameness (70%). About 99.7% of lameness was related with footroot and most appeared in winter (36.7%). In some occasions there was not a specific season distribution (56.7% rainiest years). From the analyzed farms, 70% use straw as a floor bed, followed by bush (21%). 45.6% of animals were clinically diagnosed with footrot and were sheltered in straw floor. Bed quality is good in 40%, however frequent changes in the floor bed in the preceding 15 days had a higher rate of footroot diagnosed cases (33,23%) compared to monthly changes. Regarding sheepfold animal number, the distribution is proper in 36.7%, elevated in 30%, overcrowded in 6.7% and low in 23.3%. Clinically ill diagnosed animals in last category were the lowest observed (3%). Concerning hoof trimming, 76.7% trims while 23.3% reported not to perform that task. From those that perform trimming, 73.9% do it only when necessary, 21.7% at the time of clipping and 4.4% when the animal is affected. One curious result was that animals who perform trimming at clipping had higher footrot cases (52.6%), unlike those who trim only when necessary (40.2%) or even when animals are clinically ill (0.91%). Mostly all in the presence of footrot choose a local treatment (95.2%) using antibiotic sprays, instead of parenteral antibiotic treatment. Footbath is rarely used in the prevention (13.3%) of this disease and when it is misconceived (25%) and incorrectly formulated (100%). Conclusions: This study was the first performed in Portugal focusing footrot caracterization in native SEN flocks.Economic impact in SEN dairy flocks is atributed to factors such as direct decrease in milk and meat production,early slaughter of affected animals due to non responsive treatment and medical expenses.The most effective eradication method combines first of all the ability to understand the problems of SEN producers and implementation of preventive measures and treatment of footrot.Often linked to lack of formation, the advance age of portuguese producers the mentality and social factors block the advance of veterinarian intervention itself.

Enquadramento – O contacto pele-a-pele na primeira hora de vida tem benefícios para a mãe e para o recém-nascido, bem como um papel importante no estabelecimento da amamentação. Objetivos – Analisar a evidência científica dos benefícios do contacto pele-a-pele e amamentação na primeira hora de vida; determinar a prevalência do contacto pele-a-pele e da amamentação na primeira hora de vida; verificar quais são os fatores (variáveis sociodemográficas, contextuais da gravidez e do parto, e variáveis relativas ao recémnascido) que interferem nas práticas do contacto pele-a-pele e amamentação na primeira hora de vida. Método – Revisão sistemática da literatura no estudo empírico I. Efetuou-se uma pesquisa na PUBMED, The Cochrane Library, Scielo e Google Académico, estudos publicados entre janeiro de 2011 e dezembro de 2014. Destes foram selecionados 4 estudos, posteriormente analisados, que tiveram em consideração os critérios de inclusão previamente estabelecidos. Dois revisores avaliaram a qualidade dos estudos a incluir utilizando a grelha para avaliação crítica de um estudo descrevendo um ensaio clínico prospetivo, aleatório e controlado de Carneiro (2008). No estudo empírico II seguiu-se um tipo de estudo quantitativo e descritivo simples, de coorte transversal, desenvolvido no serviço de Obstetrícia do Centro Hospitalar Cova da Beira, segundo um processo de amostragem não probabilística por conveniência (n = 382). A recolha de dados efetuou-se através da consulta dos processos clínicos, entre janeiro e dezembro de 2014, das mulheres com idade ≥ 18 anos que tiveram um parto vaginal com feto vivo após as 37 semanas de gestação. Resultados – Evidência de que o contacto precoce pele-a-pele, imediatamente após o parto, é um potencial estímulo sensorial, que abrange o aquecimento do recém-nascido e a estimulação tátil e olfativa, maior estabilização da temperatura, frequência respiratória e nível de glicémia, com diminuição do choro. Está associado à promoção espontânea da amamentação. Na amostra constituída por 382 mulheres, dos 18 aos 46 anos, verificou-se que o contacto pele-a-pele ocorreu em apenas 26,6% da amostra. Cerca de 92,6% da amostragem deu de mamar na primeira hora de vida. No grupo de mulheres em que houve contacto pele-a-pele e amamentação, prevalecem as que têm idade igual ou inferior a 34 anos (66,3%) e predomínio das mulheres que tiveram 5 ou mais consultas (95,9%) de vigilância da gravidez. Conclusão – Face a estes resultados e com base na evidência científica disponível que recomenda o contacto pele-a-pele imediatamente após o parto e promoção da amamentação na primeira hora de vida, assume-se como indispensável que os profissionais invistam na sua formação e assumam um papel importante para a realização deste contacto, estimulando e facilitando esta prática, assim como a realização de mais estudos científicos com contributos para o estabelecimento e manutenção desta prática. Palavras-chave: Contacto pele-a-pele; amamentação; primeira hora de vida.

Technology has an important role in children's lives and education. Based on several projects developed with ICT, both in Early Childhood Education (3-6 years old) and Primary Education (6-10 years old), since 1997, the authors argue that research and educational practices need to "go outside", addressing ways to connect technology with outdoor education. The experience with the projects and initiatives developed supported a conceptual framework, developed and discussed with several partners throughout the years and theoretically informed. Three main principles or axis have emerged: strengthening Children's Participation, promoting Critical Citizenship and establishing strong Connections to Pedagogy and Curriculum. In this paper, those axis will be presented and discussed in relation to the challenge posed by Outdoor Education to the way ICT in Early Childhood and Primary Education is understood, promoted and researched. The paper is exploratory, attempting to connect theoretical and conceptual contributions from Early Childhood Pedagogy with contributions from ICT in Education. The research-based knowledge available is still scarce, mostly based on studies developed with other purposes. The paper, therefore, focus the connections and interpellations between concepts established through the theoretical framework and draws on the almost 20 years of experience with large and small scale action-research projects of ICT in schools. The more recent one is already testing the conceptual framework by supporting children in non-formal contexts to explore vineyards and the cycle of wine production with several ICT tools. Approaching Outdoor Education as an arena where pedagogical and cultural dimensions influence decisions and practices, the paper tries to argue that the three axis are relevant in supporting a stronger connection between technology and the outdoor.
