Efeito de dois protocolos de irrigação final na infiltração apical de diferentes cimentos endodônticos em dentes bovinos: estudo in vitro

Dissertação para obtenção do grau de Mestre no Instituto Superior de Ciências da Saúde Egas MonizObjetivo: avaliar in vitro a interface entre a dentina e os materiais de obturação em dentes bovinos submetidos a dois protocolos de irrigação final diferentes e dois cimentos endodônticos diferentes. Materiais e Métodos: foi estudada a extensão da infiltração apical, em milímetros, através do método de cortes transversais de modo a avaliar o efeito de dois protocolos de irrigação diferentes (hipoclorito de sódio a 5,25% e clorohexidina a 2%) na capacidade de selamento apical de dois cimentos (AH Plus Jet® e GuttaFlow2®). Os resultados foram registados numa base de dados no programa Excel e analisados estatisticamente no programa IBM SPSS Statistics 22.0 (para Windows) com os testes de Kruskal-Wallis e teste post hoc. O nível de significância foi < 0,05. Resultados: o grupo que obteve maior infiltração foi o grupo 1 (irrigação final com hipoclorito de sódio a 5,25% e obturação com o cimento AH Plus Jet®) e o que teve menor foi o grupo 2 (hipoclorito de sódio a 5,25% e GuttaFlow2®), com diferenças estatisticamente significativas. Houve também diferenças estatisticamente significativas entre os grupos 2 e 3 (clorohexidina a 2% e AH Plus Jet®) e os grupos 1 e 4 (clorohexidina a 2% e GuttaFlow2®). Apesar de ter havido diferenças nos valores de infiltração entre os grupos 3 e 4, 1 e 3 e 2 e 4, nenhum apresentou diferenças estatisticamente significativas. Conclusões: os protocolos de irrigação final não influenciam a capacidade de selamento apical dos cimentos estudados. O cimento GuttaFlow2® apresentou os melhores resultados de selamento apical no entanto foi mais eficaz quando se utilizou o hipoclorito de sódio a 5,25% como irrigante final. O cimento AH Plus Jet® obteve melhores resultados de selamento apical quando o irrigante final foi a clorohexidina a 2%

Modelo de König para medir a satisfação e fidelização dos clientes através da logística reversa de pós-venda: Aplicação em uma concessionária de veículos em Joinville/SC

Este artigo tem como objetivo apresentar o modelo de satisfação desenvolvido por König (2012), adaptado do modelo ACSI, que pretendeu, através de práticas da logística reversa pós-venda aplicados em uma concessionária de veículos em Joinville/SC, contribuir na busca pela fidelização de clientes. A intenção deste modelo é medir se o construto “logística reversa de pós-venda”, através de seus serviços, juntamente com as demais variáveis, contribuem na conquista da satisfação e fidelização dos clientes compradores de automóveis. O modelo foi aplicado em clientes de uma concessionária de veículos franceses, revendedora de carros importados e nacionais. A escolha por essa concessionária de automóveis ocorreu por seus produtos serem destinados a atender um público alvo com um nível elevado de exigência. Como resultado da pesquisa, foi possível identificar que os clientes da concessionária percebem na logística reversa de pós-venda um diferencial para eliminar a reclamação e assim, tornar-se satisfeitos e fidelizados a marca

Novel insights for permeant lead structures through in vitro skin diffusion assays of Prunus lusitanica L., the Portugal Laurel

As a contribution for the generation of libraries in which a natural product (NP) is used as the guiding structure, this work sought to investigate molecular features of triterpenes as deliver leads to cross the stratum corneum at a significant rate. Seeking a bioguided investigation of the dermocosmetic lead-like potential of triterpenes in Prunus lusitanica L., various extracts were obtained by two different methods (Soxhlet extractor and Accelerated Solvent Extraction-ASE) and analyzed by GC–MS and NMR. In vitro assays were conducted to quantify the friedelin 1 and crude plant extract permeation through a membrane of polydimethylsiloxane (PDMS), as well as their skin penetration enhancement capacity using two model molecules, caffeine 19 and ibuprofen 20. Friedelin 1 was identified as the major component (16–77%, GC) with isolated yield of 51% w/w (94%, GC) from Soxhlet residue (1.7% p/p) of the dried aerial parts of the plant harvested when in early flowering stage. Friedelin 1 promoted the penetration of the lipophilic molecule 20, however, it did not influence the permeation of the hydrophilic permeant 20. On the other hand, the crude extract acted as a retardant of the penetration of both substances. Molecular characteristics for the applicability of P. lusitanica L. in the development of dermocosmetics, as well as a new potential use for friedelin 1 in particular, are demonstrated. Probable mechanisms for chemical penetration enhancement using triterpenes as models for transdermal administration are herein discussed

Cultura de segurança do doente na prática clínica dos enfermeiros

Objective: to assess the psychometric characteristics of the Hospital Survey on Patient Safety Culture, to characterize the patient safety culture, and to assess the influence of the sociodemographic and professional variables on the safety culture dimensions. Method: a methodological, observational, analytical and cross-sectional study conducted with 360 nurses in which the Hospital Survey on Patient Safety Culture questionnaire was used. The data were submitted to descriptive and inferential analysis, as well as to feasibility and validity studies. Results: the nurses’ mean age is 42 years old, their mean time of professional experience is 19 years, and they are mostly female. Good internal consistency was obtained (Cronbach’s alpha: 0.83), as well as acceptable model fit quality indices. Teamwork within units, Supervisor expectations and Feedback and communication about errors were the dimensions that obtained scores above 60%. Non-punitive response to error, Frequency of events reported, Support for patient safety and Staffing presented scores below 40%. These dimensions are influenced by age, schooling level and professional experience. Conclusion: the psychometric properties of the questionnaire certify its good quality. Teamwork can be considered as an enhancing factor for the safety culture. Assessing the safety culture allowed identifying problematic dimensions, thus enabling planning of future interventions.info:eu-repo/semantics/publishedVersio

Music Laboratory: sing to learn

No âmbito da preparação de um projeto de investigação inserido na Unidade Curricular de Pedagogia da Música do Mestrado de Ensino de Educação Musical no Ensino Básico, da Escola Superior de Educação – IPB, percebemos que preparar canções para crianças pequenas compreendia diferentes etapas de aprendizagens e que as mesmas podiam contribuir para distintas aptidões motoras, linguísticas e musicais. A literatura reforça que aprender música através de canções potencia o desenvolvimento e aprendizagem, quer da língua materna, quer dos sinais referentes à música, ou mesmo da memória e outras aptidões cognitivas e sensoriais. Deste modo, propomos apresentar um estudo de caso, com a aplicação de uma canção destinada a crianças e exemplificar as etapas da sua aprendizagem, enquanto processos para reforçar a língua materna, a géstica, o fraseado e a coordenação motora para comunicar musicalmente. Os resultados do estudo permitiram concluir que as crianças perceberam frases musicais, criaram referências linguísticas e motoras.In the preparation of a research project included in the course of Music Pedagogy of the Master in Teaching Music in Basic Education, at the School of Education – IPB, we realized that preparing songs for young children comprise different stages of learning and the same could contribute to different motor, language and musical skills. Literature reinforces that learning music through songs encourages the development and learning of both the mother tongue, the signals for the song, or even memory and other cognitive and sensory skills. Thus, we propose a case study through the application of a song to children by illustrating the stages of their learning as processes to strengthen the mother tongue, the gestures, phrasing and coordination to communicate musically. The results show that the children understood musical phrases, created language and motor references.info:eu-repo/semantics/publishedVersio
