This study used an aqueous dispersion of silanized colloidal silica (SCS), whose particles’ surfaces were modified with an epoxysilane-based coupling agent, as the liquid medium and binder for MgO-Al2O3-containing suspensions. Fine calcined alumina and magnesia sinter particles were dispersed in SCS to form a 65 vol% solids suspension. Equivalent silica-free compositions containing calcium aluminate cement or unsilanized colloidal silica were tested as references. After mixing, the SCS-suspension showed low viscosity and suitable workability and, after curing, a thin protective coating of magnesium silicate hydrate (MSH) was formed, thus preventing MgO hydroxylation and improving bonding strength, generating green-dried structures of significant flexural strength (8 MPa). During initial heating, the decomposition of MSH and the softening of amorphous silica particles reduced the overall expansion of spinel (MgAl2O4) formation. After sintering at 1600ºC, the structure showed intense densification (total porosity of 8%) high flexural strength (73 MPa) and large spinel crystals surrounded by a thin layer of amorphous silica and magnesium silicates.

ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

Abstract The magnesia (MgO) hydroxylation behavior in dilute suspensions (below 50% volumetric solid loads) has been extensively studied over the past decades due to its role in refractory castables. However, its equivalent effects on concentrated systems have not been analyzed in such a systemic way, although they are known to be as or more deleterious than those observed in dilute systems. This study focuses on the hydroxylation behavior of different sources of magnesia (sinter and caustic magnesia) in aqueous suspensions prepared at various solids concentrations (17-96 vol%) and shaped by distinct methods. They were analyzed by thermogravimetry, apparent volumetric expansion measurements, X-ray diffraction, scanning electron microscopy, and in situ temperature measurements during curing. The ratio between experimental and theoretical extents of the hydroxylation degree resulted in the reaction yield. A comparison between samples containing the same water amount revealed those with caustic magnesia showed a faster evolution of hydroxylation degree, apparent volumetric expansion, and higher maximum internal temperature during curing. In both systems, the yield levels of compositions of heavier solid loads were higher, despite the small quantity of hydroxylation products formed. Significant differences in the products’ microstructure were observed and related to the ions' mobility toward crystallization nuclei.

ABSTRACT Objective: To evaluate the oral health and related factors among people with visual impairment in a municipality in southeastern Brazil. Methods: A cross-sectional and descriptive household study was carried out on a representative sample of people with visual impairments in a medium-sized city in Brazil. A clinical-dental examination was performed (evaluating tooth loss, caries, periodontal health, dental plaque use and need of prosthesis) and a semistructured questionnaire was applied, investigating the socioeconomic conditions (sex, age, marital status, skin color and income) and the use of dental services (reason, time since, and type of service used [private/public] in last dental visit). Descriptive and bivariate analysis were performed to asses the factors related to oral health. Results: The mean age of participants was 65 years (±15.05), with the majority women (70.9%). 53.1% of the interviewees were edentulous, but 58.2% had a good perception of oral health. The blind ones use less public services (p=0.038) and with a lower frequency (p=0.014) than subjects with low vision. Those with less schooling had higher tooth loss and lower periodontal problems (p <0.05). There was a reduction of dental plaque six months after the educational action (30.7%; p=0.01), especially among the low vision participants (p=0.01). Conclusion: Severe tooth loss and unsatisfactory hygiene contrast with self-perception of oral health. Visual acuity and schooling were related to access and oral health. Actions for promotion and equity are necessary to overcome the inequalities encountered.

RESUMO Objetivo: Avaliar a saúde bucal e fatores relacionados entre deficientes visuais em município do sudeste brasileiro. Métodos: Foi realizado um estudo domiciliar, transversal e descritivo em uma amostra representativa de pessoas com deficiência visual em uma cidade de médio porte do Brasil. Realizou-se o exame clínico bucal (avaliando perda dentária, cárie, saúde periodontal, placa dentária, uso e necessidade de prótese) e aplicou-se um questionário semiestruturado, investigando as condições socioeconômicas (sexo, idade, estado civil, cor da pele e renda) e o uso de serviços odontológicos (motivo, tempo decorrido e tipo de serviço utilizado [privado/público] na última consulta odontológica). Foram realizadas análises descritivas e bivariadas para avaliar os fatores associados à saúde bucal. Resultados: A idade média dos participantes foi de 65 anos (±15,05), com maioria de mulheres (70,9%). 53,1% dos entrevistados eram edêntulos, porém, 58,2% apresentaram percepção de saúde bucal boa. Os cegos usam menos os serviços públicos (p=0,038) e em menor frequência (p=0,014) que os sujeitos com baixa visão. Os menos escolarizados apresentam maiores perdas dentárias e menores problemas periodontais (p<0,05). Houve redução de placa dentária seis meses após ação educativa (30,7%; p=0,01), sobretudo entre os sujeitos com baixa visão (p=0,01). Conclusão: Elevada perda dentária e higienização insatisfatória contrastaram com autopercepção dos agravos bucais. Acuidade visual e escolaridade relacionaram-se ao acesso e saúde bucal. Ações de promoção e equidade são necessários para superar desigualdades encontradas.

Abstract Background Patients with chronic renal failure may have their oral health impaired as a result of the disease itself, its treatment, and its associated lifestyle alterations. Objective To assess the factors associated with poor self-rated oral health among adults with chronic renal failure treated by hemodialysis. Method This is a cross-sectional study with 243 adults undergoing hemodialysis in a hospital in Minas Gerais, Brazil in 2013-2014. The outcome was assessed by the self-report of oral health categorized into good (excellent/good) and bad (fair/bad / very bad). The independent variables included sociodemographic conditions, general health, oral health, and the use of dental services were collected through a structured questionnaire. The association between the outcome and the independent variables was tested using multiple logistic models with hierarchical inclusion of variables. Results The prevalence of poor self-rated oral health was 35.4%. The youngest (p = 0.015), those who have undergone hemodialysis in the shortest time (p = 0.016), have halitosis (p <0.001), need dental treatment (p <0.001), and had their last dental appointment not for pain (p = 0.027) expressed higher odds of poor self-rated oral health, independently of sociodemographic and health conditions.

RESUMO O objetivo deste artigo é propor e validar um modelo de escala de componentes da estrutura organizacional (ECEO), a partir dos componentes latentes identificados no estudo exploratório de Trigueiro-Fernandes (2014), que se inspirou nos parâmetros de design de Mintzberg (2012). Para tanto, a pesquisa foi realizada em 26 unidades organizacionais públicas e privadas. A Análise Fatorial Confirmatória foi adotada para avaliar as propriedades do modelo ECEO e sua adequação com a teoria. Os resultados indicaram que a escala possui boa qualidade de ajuste, verificada por meio índices de ajustamento χ²/df, RMSEA, CFI, TLI e SRMR, assim como pelos testes de validade convergente, validade discriminante e confiabilidade composta propostas. Foram identificados os componentes de Estrutura Organizacional: formalização, comunicação, descentralização, treinamento e internalização, departamentalização e hierarquia. Permitindo inferir que a estrutura é o meio pelo qual se organizam as interações entre pessoas e processos, bem como se identificam mecanismos de coordenação para o atingimento da missão organizacional.

ABSTRACT This study aims to proposed and validate a scale of organizational structure components (SOSC) from the latent components identified in the exploratory study by Trigueiro-Fernandes (2014), inspired by the design parameters of Mintzberg (2012). The survey was conducted in 26 public and private organizational units. Confirmatory Factor Analysis was employed to assess the SOSC model properties and whether they fit the theory. The results show that the scale has acceptable goodness of fit, verifiable through adjustment indexes such as χ²/df, RMSEA, CFI, TLI, and SRMR, as well as composite reliability, convergent and discriminant validity tests. The identified organizational structure components were formalization, communication, decentralization, training and internalization, departmentalization, and hierarchy. The results allow us to infer that the structure is the means by which the interactions between people and processes are organized and as coordination mechanisms for achieving the organizational mission are identified.

Resumo Entre os componentes de uma edificação passiva, a cobertura é particularmente importante para a regulação das condições térmicas internas. Dos sistemas para resfriamento passivo que atuam a partir da cobertura, cita-se o teto-reservatório (TR). Quando o TR é acoplado a painéis radiantes que utilizam água como fluido, pode alcançar alta eficiência energética, potencializando o desempenho da fonte do suprimento de frio. No momento, faltam estudos sobre a aplicação conjunta dessas tecnologias. Esta pesquisa teve como objetivo avaliar os desempenhos térmicos de diferentes configurações de TR, com e sem painéis radiantes, aplicadas a um ambiente de uma edificação-teste no verão. O experimento ocorreu no campus Sde Boqer, da Universidade Ben-Gurion de Negev, em Israel. Como parâmetro para comparação, utilizou-se a cobertura original da edificação-teste. Avaliou-se o desempenho térmico ante as normas Standard 55 e EN 15251, a estabilização das temperaturas internas e o resfriamento. O sistema apresentou bons resultados em se tratando da moderação das condições térmicas externas, especialmente quando considerada a norma europeia EN 15251.

Abstract Among the components of a passive building, the roof is particularly important for the regulation of internal thermal conditions. Among the passive cooling systems that act from the roof, we can mention the roof pond (RP). In turn, radiant panels that use water as fluid can achieve high energy efficiency, enhancing the performance of the cold supply source. However, studies on the joint application of these technologies are lacking. This research study aimed to evaluate the thermal performances of different RP configurations, with and without radiant panels, applied to a test building during the summer. The experiment took place at the Sde Boqer Campus, Ben-Gurion University of Negev, Israel. The test environment with a conventional local roof was used as a parameter for comparison. The thermal performance was evaluated using Standard 55 and EN 15251, stabilisation of internal temperatures, and cooling. Compared to the conventional roof, the RP presented good results in terms of the moderation of the thermal conditions of the test building, especially when considering the European standard EN 15251.

Resumo Tetos-reservatório (TR) podem colaborar para obtenção de condições térmicas confortáveis, particularmente em edificações térreas. Possibilitam resfriamento ou aquecimento estrutural e estabilização das temperaturas superficiais e do ar. Uma alternativa para melhorar o desempenho do TR é acoplá-lo a painéis radiantes. Atualmente, há escassez de pesquisas enfocando a percepção térmica de usuários em ambientes fechados condicionados por TR. O objetivo desta pesquisa foi verificar, empiricamente, para condições de verão, a percepção térmica de voluntários em um ambiente condicionado por painéis radiantes acoplados a TR. Buscou-se também identificar qual modelo adaptativo melhor representaria os votos declarados pelos participantes do estudo. Como parâmetros para análise das percepções térmicas reportadas, adotaram-se o modelo PMV e os modelos para edificações passivas das normas Standard 55 e EN 15251. O experimento ocorreu em uma edificação-teste da Ben-Gurion University of Negev, em Israel. Foram consideradas respostas de 46 voluntários. O ambiente dotado de TR foi percebido como confortável pela maior parte dos voluntários. As respostas subjetivas apresentaram maior concordância com os modelos PMV e da EN 15251 do que com o modelo da ASHRAE.

Abstract Roof ponds (RP) can promote comfortable thermal conditions, particularly in single-storey buildings. They allow structural cooling or heating and the stabilisation of surface and air temperatures. When coupled to radiant panels cooled by the exposed pond, they can further improve their thermal performance. However, there is a lack of research on RP focusing on the thermal perception of users indoors. The main objective of this study was to verify, empirically, under summer conditions, the thermal perceptions of volunteer participants in an indoor environment conditioned by a system composed of radiant panels coupled to a RP. We also sought to identify which adaptive model best represents the thermal votes reported by the study participants. As parameters for analysis of reported thermal votes, the PMV model and the passive building model of ASHRAE Standard 55 and EN-15251 were employed. The experiment took place in a test building at Ben-Gurion University of Negev, Israel. The sample consisted of 46 volunteer participants. The RP environment was perceived as comfortable by most volunteers. The thermal votes showed more agreement with the PMV and EN 15251 models than with the ASHRAE model.

ABSTRACT Objective: To evaluate both knowledge and attitude of public elementary school teachers in Alfenas, Minas Gerais, Brazil, towards Traumatic Dental Injuries (TDIs). Material and Methods: Four hundred and seventy-one teachers from 10 schools were invited to participate in the research. Two hundred and twelve were accepted, being randomly selected to answer semi-structured questionnaires. Statistical tests Chi-Square and Fisher’s Exact Test were also used for the other variables at a significance level of 5% (p<0.05). Results: 212 teachers answered; 34% had first-aid training in college or even voluntarily (22.6%), but only 7.1% had taken training about TDIs. Only 7.5% were satisfied with the knowledge about TDIs, and 12.3% felt prepared to face it. About 10.8% had seen any type of TDI; 53.3% would report to the headmaster and 8% to the school dentist in a TDI event. The teachers’ first attitude towards TDIs would be contacting the child’s parents (63.2% and 58.5%, respectively). About 47.2% would handle the tooth properly (by the crown). Nearly 90.1% would carry out a permanent tooth dental reimplant, which would be conducted immediately (71.2%). About 36.3% of the teachers storage the avulsed tooth in a liquid: milk (46.7%) and saline solution (24.7%). The dry media mentioned were paper (18.9%) and gauze or cotton (15.1%). Most of the teachers (96.2%) stated that they would like to receive information on TDI. Conclusion: Elementary school teachers in Alfenas have partial knowledge about traumatic dental injuries.

ABSTRACT Crabs use burrows to prevent predation, environmental interference and shelter. The present study investigated the excavation behavior of the trichodactylid crab Dilocarcinus pagei, considering the biometric aspects of the burrows, the excavation time, the amount of bioturbation and the excavation behavior of the two sexes. The burrows of males had a mean diameter larger than the females, although the depth was similar for both sexes. Females had higher bioturbation than males, and showed enlargement in a camera format at the bottom, even closing the entrance of the burrows with a “plug” after their construction. Both the camera and the presence of the “plug” in the burrows of the females may be associated with reproduction. The presence of pellets observed at the entrance of burrows is associated with the cleaning of the pereiopods by crabs after the excavation. The sequence of behaviors for the construction of the burrows is described in detail, contributing to the knowledge about the biology and ecology of freshwater crabs of the Amazon.

Resumo Objetivo O Teste Shuttle Modificado é um teste clínico de campo que evita o efeito-teto e não existem relatos de avaliação multidimensional com relação à atividade física em pacientes com asma. Assim, o objetivo era avaliar a capacidade funcional, a atividade física na vida cotidiana, a força muscular e os níveis de citocina em crianças e adolescentes com asma, a fim de correlacionar essas variáveis. Método Este estudo transversal incluiu voluntários entre seis e 18 anos, os quais foram divididos em dois grupos: o grupo com asma (n = 43), que recebeu tratamento regular, e o grupo de controle (n = 24). A capacidade funcional foi avaliada pela distância percorrida durante o Teste Shuttle Modificado, ao passo que a atividade física na vida cotidiana foi avaliada utilizando um acelerômetro pelo número de passos. A força muscular do quadríceps femoral foi avaliada por uma célula de carga. Resultados A distância percorrida foi menor no grupo com asma (790 m [222 m]) em comparação com o grupo de controle (950 m [240 m]; p = 0,007), contudo o número de passos foi semelhante nos dois grupos (grupo com asma: 7.743 [3.075]; grupo de controle: 7.181 [3.040]; p = 0,41) e ambos os grupos foram classificados como sedentários. Não houve diferença na avaliação da força muscular. O fator de necrose tumoral-α apresentou divergências, porém os níveis de interleucina foram semelhantes entre os grupos. A força muscular do quadríceps foi correlacionada com a distância percorrida (r: 0,62; p < 0,001) e o fator de necrose tumoral-α, ao número de passos dados (r = −0,54, p = 0,005). Conclusão Crianças e adolescentes que recebem tratamento regular de asma apresentaram redução da capacidade funcional e comportamento sedentário. Quanto menor a força muscular do quadríceps, menor a distância percorrida; quanto maiores os níveis de fator de necrose tumoral-α, menores seus níveis diários de atividade física.

Abstract Objective The modified shuttle test is a field test that avoids the ceiling effect, and there are no reports of a multidimensional assessment concerning physical activity in asthmatic patients. Thus, the aim was to evaluate functional capacity by MST, additionally to perform a multidimensional assessment as physical activity in daily life, muscle strength, and cytokine levels in children and adolescents with asthma, and to correlate these variables. Method This cross-sectional study included volunteers aged between 6 and 18 years who were divided into two groups: asthma group (n = 43) that received regular treatment and control group (n = 24). Functional capacity was evaluated by distance walked during the MST; physical activity in daily life was evaluated using an accelerometer by the number of steps. Quadriceps femoris strength was evaluated by load cell. Results Distance walked was lower for the asthma group (790 m [222 m]) when compared with the control group (950 m [240 m]; p = 0.007); however, the number of steps was similar between the two groups (asthma group: 7743 [3075]; control group: 7181 [3040]; p = 0.41), and both groups were classified as sedentary behavior. There was no difference in muscle strength. Tumor necrosis factor-α differed, but interleukin levels were similar between groups. Quadriceps strength was correlated to distance walked (r = 0.62; p < 0.001) and tumor necrosis factor-α to the number of steps taken (r = −0.54, p = 0.005). Conclusion Children and adolescents undergoing regular asthma treatment showed reduced functional capacity and sedentary behavior. The lower the quadriceps strength, the shorter the distance walked; the higher the tumor necrosis factor-α levels, the lower their daily physical activity levels.

RESUMO O comprometimento organizacional, apesar de muito estudado, ainda permanece na agenda de pesquisa devido à falta de consenso nas questões conceituais e estruturais. Deste modo, esta pesquisa se propôs a refinar a Escala de Bases do Comprometimento Organizacional (EBACO) em busca de um instrumento com melhores propriedades psicométricas e maior adequação teórica. A pesquisa se dividiu em duas fases, e a primeira, eminentemente exploratória, realizada com 149 observações, avaliou o ajuste psicométrico da EBACO com a redução de duas bases. A segunda fase, confirmatória, se deu em 45 organizações - sendo 27 públicas e 18 privadas, totalizando 812 observações. A análise fatorial confirmatória foi adotada para avaliar as propriedades psicométricas e adequação teórica do modelo reduzido. Os resultados indicaram que com cinco dimensões o modelo EBACO apresentou maiores índices de KMO, alpha de Cronbach e variância explicada. Constatou-se, também, que o modelo discutido obteve valores adequados dos índices de ajustamento χ2/df, RMSEA, CFI, TLI e RMR. Por fim, foi verificado que o modelo refinado, EBACO-R, apresentou validade convergente, garantindo maior adequação da escala à teoria. Além disso, o refinamento do modelo, com a exclusão das bases, colabora com a discussão de Osigweh (1989) sobre o “esticamento do conceito” de comprometimento.

ABSTRACT Despite being extensively studied, the organizational commitment still remains in the research agenda due to a lack of consensus on conceptual and structural issues. Therefore, this research proposed to refine the Organizational Commitment Bases Scale (EBACO) in search for an instrument with better psychometric properties and a better theoretical adjustment. The research was divided into two phases, the first one was eminently exploratory, carried out with 149 observations, and evaluated the EBACO’s psychometric fitting with the reduction of two bases. The second phase, confirmatory, occurred in 45 organizations - 27 public and 18 private, with 812 observations. The confirmatory factor analysis was adopted to evaluate the psychometric properties and the theoretical adequacy of the refined model. The results indicated that with five dimensions the EBACO model presented higher levels of KMO, Cronbach’s Alpha, and explained variance. It was also verified that the model discussed obtained adequate values of the goodness of fit indexes χ2/df, RMSEA, CFI, TLI and RMR. Finally, it was verified that the refined model, EBACO-R, presented a convergent validity, ensuring a greater suitability of the scale to the theory. Furthermore, the model refinement, excluding the bases, contributes to the discussion by Osigweh (1989) about the 'concept stretching' commitment.
