Formação de professores : uma experiencia que articula teoria e pratica

Orientador: Ulisses Ferreira de AraujoDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de EducaçãoResumo: Este trabalho discute a experiência que foi implantada em uma escola pública municipal no interior do estado de São Paulo. Fundamentado em autores que propõem que a formação de professores e sua formação continuada devem basear-se na articulação entre a teoria e a prática pedagógica, sem fragmentar o conhecimento, o trabalho toma como referenciais a interdisciplinaridade, a transversal idade na educação e as idéias da Pedagogia de Projetos.Trabalhamos com duas professoras que, durante o ano 2000, desenvolveram sua prática profissional em um espaço denominado "Oficina de Talentos". Esse trabalho ocorreu dentro da própria instituição escolar, com crianças de 7 a 10 anos de idade, por meio da Pedagogia de Projetos.No ano 2001 essas professoras voltaram para suas salas de aula regulares e constatamos que houve transformações em sua prática pedagógica, com a incorporação no cotidiano de seu trabalho dos pressupostos teóricos e práticos da interdisciplinaridade, da transversal idade e da Pedagogia de Projetos.Tal análise dos resultados foi feita a partir de três aspectos distintos e complementares: as mudanças na prática pedagógica; a não fragmentação do conhecimento; e a busca de novas estratégias de trabalho e temas, a partir das relações teoria/práticaAbstract: This work discusses an experience implanted in a public school located in the country side of São Paulo. On the bassis of authors who propose that the formation and continued formation of professors and teachers must be based on both the practical theory and the pedagogical one, without fragmenting the knowledge, the work takes as reference the interdisciplinarity, the transversality in the education and the ideas of the Pedagogy of Projects.We have worked with two teachers who, in the year 2000, developed their professional practice space called "Workshop of Talents". This work occurred inside the school, with children ranging from 7 to 10 years of age, by means of the Pedagogy of Projects. In the year 2001 these teachers went carne back to their regular classrooms and we could notice that there were transformations in their pedagogical pratice, with the incorporation of the presupposed theory and pratice of the interdisciplinarity, the transversality and the Pedagogy of Projects in their daily work. Such analysis of the results was made from three distinct and complementary aspects: the changes in the pedagogical pratice; the nom fragmentation of knowledge; and the search of new strategies of work and thems, from the relations theory/practiceMestradoMestre em Educaçã

Against the Norm: Do Not Rely on Serum C-Reactive Protein and White Blood Cell Count Only When Assessing Eradication of Periprosthetic Joint Infection

Introduction: Periprosthetic joint infections (PJI) following primary arthroplasty continue to be a serious complication, despite advances in diagnostics and treatment. Two-stage revision arthroplasty has been commonly used as the gold standard for the treatment of PJI. However, much discussion persists regarding the interim of the two-stage procedure and the optimal timing of reimplantation. Serology markers have been proposed as defining parameters for a successful reimplantation. The objective of this matched-pair analysis was to assess the role of serum C-reactive protein (CRP) and white blood cell count (WBC) in determining infection eradication and proper timing of reimplantation. We investigated the delta (∆) change in CRP and WBC values prior to both stages of two-stage revision arthroplasty as a useful marker of infection eradication. Methods: We analyzed 39 patients and 39 controls, matched by propensity score matching (BMI, age, ASA-classification), with a minimum follow-up of 24 months and treated with a two-stage revision THA or TKA in our institution. Data of serum CRP and WBC values were gathered at two selected time points: prior to the explantation of the implant (preexplantation) and following the completion of antibiotic treatment regimen, both systemic and with a drug-eluting cement spacer (prereimplantation). Patient records were reviewed electronically for preexisting comorbidities, overall health status, synovial fluid cultures, inflammatory serologies, revision surgeries, and recurrent or persistent infection based on the modified Musculoskeletal Infection Society criteria. Patient demographics, ∆CRP, ∆WBC, and time interval to reimplantation were statistically analyzed using receiver operator curves (ROC), Pearson’s correlation coefficient, Levene’s test, and Student’s t-test. Results: Infection-free patients exhibited higher mean CRP and WBC than did patients who were reinfected at both time points. When comparing preexplantation with prereimplantation values, the median ∆CRP was 9.48 mg/L (interquartile range (IQR) 2.3–36.6 mg/L) for patients who did not develop a reinfection versus 2.74 mg/L (IQR 1.4–14.2 mg/L) for patients who developed reinfection (p = 0.069). The median ∆WBC was 1.5 × 109/L (IQR 0.6–4.0 × 109/L) for patients who remained infection-free versus 1.2 × 109/L (IQR 0.8–2.2 109/L) for patients who developed reinfection (p = 0.072). Analysis of areas under the curve (AUC) using ROC demonstrated poor prediction of persistent infection by ∆CRP (AUC = 0.654) and ∆WBC (AUC = 0.573). Although a highly significant correlation was found between the interim interval and infection persistence (r = 0.655, p < 0.01), analysis using ROC failed to result in a specific threshold time to reimplantation above which patients are at significantly higher risk for reinfection (AUC = 0.507). Conclusion: No association could be determined between the delta change in serum CRP and WBC before and after two-stage revision arthroplasty for PJI and reinfection risk. Even though inflammatory serologies demonstrate a downtrending pattern prior to reimplantation, the role of CRP and WBC in determining the optimal timing of reimplantation seems to be dispensable. Planning a second-stage reimplantation requires assessing multiple variables rather than relying on specific numeric changes in these inflammatory marker values

Lacustrine mineral facies and implications for estimation of palaeoenvironmental parameters: Neogene intervolcanic Pelitçik Basin (Galatean Volcanic Province), Turkey

The mineralogy of the Neogene lacustrine facies of Pelitcik basin was investigated for the purpose of deriving the palaeoenvironmental parameters of this intervolcanic basin. The laboratory studies indicate that dolomite and K-feldspar are the major non-clay minerals in the study area, where plagioclase, analcime, fibrous zeolite and quartz are the minor constituents. Dolomites are found to be non-stoichiometric in chemistry. The clay fraction of the lacustrine facies is composed mainly of dioctahedral smectites. The smectites are rich in Al-Fe indicating a detrital origin. Illite comprises a minor contribution to the clay fraction, where chlorite and kaolinite are found in trace amounts. Based on dolomite stoichiometry and the mineral paragenesis found in the Pelitcik basin, the depositional conditions are suggested to have been a shallow, quiet, perennial lacustrine environment with fresh to slightly saline and slightly alkaline water chemistry. In addition, based on geological and mineralogical constraints, it is suggested that the water chemistry fluctuated during the deposition of the Pazar formation and the lake began its evolution with a hydrologically closed system and completed its evolution with a hydrologically open system
