Efeito da irrigação passiva ultrassônica na difusão de íons hidroxila através da dentina radicular: estudo ex vivo

TCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Odontologia.O objetivo deste trabalho foi avaliar o efeito da irrigação ultrassônica passiva (IUP) na difusão, através da dentina radicular, de íons hidroxila provenientes da pasta de hidróxido de cálcio (HC). Após o preparo químico-mecânico dos canais radiculares de 50 dentes humanos, a camada de cemento foi removida e a superfície radicular externa lavada com EDTA 17% e NaOCl 1%. A região da junção amelocementária e os 3 mm da porção apical de cada raiz foram recobertas com Araldite. Quatro protocolos diferentes de irrigação final foram realizados, com n=10 em cada grupo: Grupo 1 - irrigação com EDTA e NaOCl; Grupo 2 - irrigação com EDTA + IUP + NaOCl; Grupo 3 - irrigação com EDTA + NaOCl + IUP; Grupo 4 - irrigação com EDTA e NaOCl, ambos com IUP. Cinco dentes foram somente irrigados com água destilada (Grupo 5) e outros 5 irrigados com água destilada + IUP (Grupo 6), servindo de controle. Em seguida, os canais foram secos, preenchidos com HC e mantidos em frascos plásticos individuais, contendo 10 mL de água destilada com pH conhecido. Nos períodos de 7, 15 e 21 dias, o pH da água contida nos frascos foi aferido. Os valores de pH foram tabulados e comparados pelo teste de análise de variância (ANOVA2) e o teste de Tukey foi empregado para comparações individuais (α=0,05). Não houve diferença estatisticamente significante entre os grupos (p=0,1224), mas houve entre os períodos experimentais (p<0,0001). Em 15 e 21 dias houve maior difusão de íons do que em 1 semana. Concluiu-se que a irrigação ultrassônica passiva não influenciou na difusão dos íons hidroxila através da dentina radicular.The aim of this study was to evaluate the Passive Ultrassonic Irrigation (PUI) effect on hydroxyl ions diffusion arising from calcium hydroxide paste (CH) among root dentin. Fifty humans teeth were endodontically prepared. The cement layer was removed and the external root surface was washed with EDTA and NaOCl. The cementoenamel junction and the apical portion of each root was covered. Four different protocols for final irrigation were employed (n=10): Group 1 - final irrigation with EDTA + NaOCl, Group 2 - final irrigation with EDTA + PUI + NaOCl, Group 3 – final irrigation with EDTA + NaOCl + PUI and Group 4 - final irrigation with EDTA + NaOCl both with PUI activation. Five teeth received only distilled water as final solution (Group 5) and other five were irrigated with distilled water + PUI (Group 6) working was control group s. The root canal was then dried and filled with CH. The specimens were individually kept in plastic vials containing distilled water (10mL) with a known pH. After 7, 15, and 21 days the pH from the specimens distilled water was verified. This values were recorded and compared by using ANOVA and Tukey’s test was used to individuals comparisons (α=0.05). No statistically significant difference was observed between the groups (p=0.1224). But it was observed among the different periods (p<0.0001). In the 15 and 21 days period was more OH-diffusion when compared to the 7 days analysis. It was concluded that PUI did not influence on OH- diffusion among radicular dentin

A Phenomenological Study of Female Gender Inequality in the Defense Industry

Despite advances made during the women\u27s movement, gender inequality is a problem for women seeking leadership opportunities within the U.S. Defense Industry today. The purpose of this phenomenological study was to understand the perceptions of civilian females who had experienced gender inequality obstacles in their professional advancement opportunities within the U.S. Defense Industry. The mommy track framework, defined as the family/work imbalance; the gatekeeper framework; and the institutional sexism framework were used to guide this study. The research questions focused on how these women perceived both internal and external barriers to their professional advancement in the U.S. Defense Industry. A criterion sample of 18 civilian females who worked within the defense industry was interviewed. Data analysis included coding, categorizing, and analyzing themes. The resulting 5 themes were worker bee, traditional mentality/transitional workforce, education/training/network, traditional organizational culture, and fighting back. The findings also identified that gender inequality is apparent, women limit their potential growth, Queen Bees sting Wanna-Bees, and traditional organizational cultures maintain the status quo as the norm and enforce gendered stereotypes. The study leads to positive social change by raising awareness to policy-makers, educators, and women that can help set an agenda to overcome gender inequality

Strategies for the implementation of local food policy in New York City

Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2009.Includes bibliographical references (p. 39-44).This thesis is an exploration into how New York City can incorporate local food system planning into their existing sustainability program by capitalizing on recent energy and grassroots initiatives. I argue for the importance of local and regionally produced food as a part of food system sustainability, and propose that food issues be addressed at the local level. In order to learn how food planning transforms from a social and advocacy movement and into policy, I compare food policy initiatives in Chicago, San Francisco, and Vancouver. My analysis of each city's food program reveals their shared aspiration to provide affordable, accessible, and fresh food with few adverse environmental impacts. Each city's strategies are the product of local conditions, interests, and political culture. I recommend that as the New York City government looks towards coordinating food policy, these precedents illustrate the necessity of tailoring urban food policy practices to suit local conditions, community culture, and needs. This paper evaluates the effectiveness of nascent food policy efforts while suggesting roles for policy makers, community groups, and citizens in New York City.by Deborah Helaine Morris.M.C.P

Personality representation: predicting behaviour for personalised learning support

The need for personalised support systems comes from the growing number of students that are being supported within institutions with shrinking resources. Over the last decade the use of computers and the Internet within education has become more predominant. This opens up a range of possibilities in regard to spreading that resource further and more effectively. Previous attempts to create automated systems such as intelligent tutoring systems and learning companions have been criticised for being pedagogically ineffective and relying on large knowledge sources which restrict their domain of application. More recent work on adaptive hypermedia has resolved some of these issues but has been criticised for the lack of support scope, focusing on learning paths and alternative content presentation. The student model used within these systems is also of limited scope and often based on learning history or learning styles.This research examines the potential of using a personality theory as the basis for a personalisation mechanism within an educational support system. The automated support system is designed to utilise a personality based profile to predict student behaviour. This prediction is then used to select the most appropriate feedback from a selection of reflective hints for students performing lab based programming activities. The rationale for the use of personality is simply that this is the concept psychologists use for identifying individual differences and similarities which are expressed in everyday behaviour. Therefore the research has investigated how these characteristics can be modelled in order to provide a fundamental understanding of the student user and thus be able to provide tailored support. As personality is used to describe individuals across many situations and behaviours, the use of such at the core of a personalisation mechanism may overcome the issues of scope experienced by previous methods.This research poses the following question: can a representation of personality be used to predict behaviour within a software system, in such a way, as to be able to personalise support?Putting forward the central claim that it is feasible to capture and represent personality within a software system for the purpose of personalising services.The research uses a mixed methods approach including a number and combination of quantitative and qualitative methods for both investigation and determining the feasibility of this approach.The main contribution of the thesis has been the development of a set of profiling models from psychological theories, which account for both individual differences and group similarities, as a means of personalising services. These are then applied to the development of a prototype system which utilises a personality based profile. The evidence from the evaluation of the developed prototype system has demonstrated an ability to predict student behaviour with limited success and personalise support.The limitations of the evaluation study and implementation difficulties suggest that the approach taken in this research is not feasible. Further research and exploration is required –particularly in the application to a subject area outside that of programming
