Dificuldades relatadas por estudantes de odontologia diante de procedimentos relacionados à periodontia

Objective: This study aimed at evaluating the difficulties reported by last-year dentistry course students regarding basic and surgical periodontal procedures. Methods: A proposed questionnaire with 24 questions, 14 related to basic periodontal procedures and 10 to surgical procedures, was applied to 45 undergraduate students with jobs involving these procedures, during the practical activities of the Integrated Clinic Discipline, a compulsory subject in the curriculum of the course, taught to last-year students. Students were asked about their own perceptions of the difficulties in implementing the various steps related to the treatments. The degree of individual difficulty was determined according to the Likert scale: 0 = none, 1 = mild, 2 = moderate, 3 = high, 4 = very high. Exploratory analysis of data was applied, and the difficulty level was also dichotomized into none to mild (scores 0 and 1) and moderate to very high (scores 2–4). Results: Regarding the basic periodontal treatment, bone level probing was the procedure with the highest number of student difficulties (57.5%). As for the difficulties reported by students regarding the stages of periodontal surgery, only the procedures related to anesthesia and suture removal had no report of doubts. Conclusion: Periodontal surgery was the procedure involving the most prevalent questions reported as moderate to very high, and the indication for the most suitable surgical technique was the stage with the highest percentage of questions (66.6%) among the undergraduates.

Avaliação psicométrica da escala de atitudes em relação à estatística

RESUMO: O objetivo do estudo foi estimar a validade e confiabilidade da Escala de atitudes em relação à Estatística (EAE) quando aplicada a estudantes de Ciências Farmacêuticas. A amostra de 253 estudantes foi subdividida em duas partes. Sessenta por cento da amostra foi utilizada para explorar a estrutura fatorial e 40% para confirmá-la. Para verificar a reprodutibilidade da escala a mesma foi aplicada em duplicata a 40 estudantes. Aplicou-se o Teste de esfericidade de Bartlett e o índice Kaiser-Meyer-Olkin (KMO). A extração dos fatores foi realizada pela Análise de Componentes Principais. Realizou-se rotação ortogonal Varimax. Calculou-se o Coeficiente alfa de Cronbach (α) e o Coeficiente de Correlação Intraclasse (ρ). Realizou-se análise fatorial confirmatória. Elaborou-se um modelo hierárquico de segunda ordem (MHSO). O teste de esfericidade de Bartlett e o índice KMO foram excelentes (χ 2 =1835,815, p<0,001; KMO=0,935). Verificou-se dois fatores com valores próprios acima de 1 (λ=9,748; λ=2,086) explicando 59,2% da variância total. A questão 2 foi removida. Observou-se excelente consistência interna e reprodutibilidade. O modelo fatorial apresentou índices de qualidade de ajustamento bons (λ=0,59-0,86, χ 2 /gl=1,691, CFI=0,919, GFI=0,804, RMSEA=0,079). A validade discriminante dos fatores foi adequada. A EAE apresentou estrutura bifatorial na amostra com níveis de validade e confiabilidade adequados.

Validez y confiabilidad de la versión en español de la escala multidimensional de la UNESP-Botucatu para evaluar el dolor postoperatorio en gatos

This study focused on the validation of the Spanish version of the UNESP-Botucatu multidimensional composite pain scale to assess postoperative pain in cats. The original scale in Portuguese was translated into Spanish by two independent translators, and summarised in one version by a third individual. The summarised version was back-translated and minor adjustments were made. The scale was reviewed by three anesthesiologists with Spanish as their first language, and the final version was submitted to psychometric testing. Thirty cats undergoing ovariohysterectomy were video recorded during the perioperative period. Six observers from different spanish speaking countries, who had Spanish as the first language watched the videos and determined the pain scores using the Spanish version of the scale, identifying the cats that should receive analgesics. Videos were reanalysed in a different order about 2 months after the first assessment. The sensitivity to change, content and construct validity were established by the significant change in pain scores in response to surgery and analgesics. The agreement between the evaluations of the 'gold standard'(researcher that developed the scale) and the other observers confirmed the criterion validity. Inter- and intra-rater reliability, evaluated by intra-class correlation coefficient, ranged from good to very good for all scale items. The cut-off point for rescue analgesia identified by Receiver Operating Characteristic curve was > 7 with 92% of sensitivity and 91% of specificity. The Spanish version of the UNESP-Botucatu multidimensional composite pain scale is interpretable (has an optimal analgesic intervention score), valid and reliable instrument for assessing acute pain in cats undergoing ovariohysterectomy.

Concepciones de futuros profesores de biología, brasileros y portugueses sobre valores eticos de la ciencia

One of the science education objective, based on relationships between science, technology, society and environment (STSE) is, to form citizens capable on evaluating and taking decisions about the scientific advances impact on society and environment. In a two-way perspective, understand relationships between STSE, provides a vision of science as a human construction and therefore fallible, changeable and not neutral. In this study, we present some results from a comparative study on the influence of ethical conceptions of the nature of science, in two groups of future biology teachers, one from Brazil and, another one from Portugal. For data collection we constructed an attitude scale of Likert-type, which was validated mathematically and semantically. Results shows strong influence of social values, as in transgenic products, where the students’ ideas varied according to the ethical discussions more present in each country.

Currently has few studies today concerning the behavior of the ethyl alcohol hydrated combustible in the geological environment, results of eventual spill or leaks in a wide transport chain and distribution. This work discusses the results of an experiment in laboratorial scale, that involves the monitoring of alterations in physical properties a simulate leak of alcohol in a tank with sand saturated in water, during 4920 hours. Are applied electrical resistivity, induced polarization and spontaneous potential geophysical methods. The electric resistivity is clearly correlating to the ethanol degradation pattern. The chargeability demonstrated sensibility to this pattern, while the natural electric potential revealed direct association with the oscillations of groundwater level. The variability of the physical parameters monitoring probable control for ethanol degradation process in environment study.

Avaliação do desempenho de uma unidade em escala real para tratamento de água pluvial empregando a filtração direta por meio de filtro de pressão e amido natural de milho como coagulante primário

The aim of this study was to investigate the performance of an experimental rainwater treatment system for non-potable uses. Without the first-flush discharge it was expected to control the quality of captured rainwater and to minimize the rainwater by-pass caused by the first-flush strategy. A full-scale direct filtration unit was operated and a solution of natural corn starch was used as the primary coagulant. The color, turbidity e coliform efficiencies of the unit was analyzed based on filtration loads and the net water production was estimated. The results pointed out turbidity removal up to 70.8% and color removal up to 61.0%. The backwash of the filtering system was completed in 3 minutes at the rate of 1,440 m3/m2day with consumption of treated water from 0.5% to 2.2%, based on the potentially harvesting.
