Background: The identification of patterns of inappropriate antimicrobial prescriptions in hospitals contributes to the improvement of antimicrobial stewardship programs (ASP). Methods: We conducted a cross-sectional study to identify predictors of inappropriateness in requests for parenteral antimicrobials (RPAs) in a teaching hospital with 285 beds. We reviewed 25% of RPAs for therapeutic purposes from y 2005. Appropriateness was evaluated according to current guidelines for antimicrobial therapy. We assessed predictors of inappropriateness through univariate and multivariate models. RPAs classified as 'appropriate' or 'probably appropriate' were selected as controls. Case groups comprised inappropriate RPAs, either in general or for specific errors. Results: Nine hundred and sixty-three RPAs were evaluated, 34.6% of which were considered inappropriate. In the multivariate analysis, general predictors of inappropriateness were: prescription on week-ends/holidays (odds ratio (OR) 1.67, 95% confidence interval (CI) 1.20-2.28, p = 0.002), patient in the intensive care unit (OR 1.57, 95% CI 1.11-2.23, p = 0.01), peritoneal infection (OR 2.15, 95% CI 1.27-3.65, p = 0.004), urinary tract infection (OR 1.89, 95% CI 1.25 -2.87, p = 0.01), combination therapy with 2 or more antimicrobials (OR 1.72, 95% CI 1.15-2.57, p = 0.008) and prescriptions including penicillins (OR 2.12, 95% CI 1.39-3.25, p = 0.001) or 1(st) generation cephalosporins (OR 1.74, 95% CI 1.01-3.00, p = 0.048). Previous consultation with an infectious diseases (ID) specialist had a protective effect against inappropriate prescription (OR 0.34, 95% CI 0.24-0.50, p < 0.001). Factors independently associated with specific prescription errors varied. However, consultation with an ID specialist was protective against both unnecessary antimicrobial use (OR 0.04, 95% CI 0.01-0.26, p = 0.001) and requests for agents with an insufficient antimicrobial spectrum (OR 0.14, 95% CI 0.03-0.30, p = 0.01). Conclusions: Our results demonstrate the importance of previous consultation with an ID specialist in assuring the quality of prescriptions. Also, they highlight prescription patterns that should be approached by ASP policies.

A sociedade contemporânea vê-se desafiada a responder qualitativamente às demandas da ciência e da tecnologia, cujas ressonâncias afetam as múltiplas dimensões humanas. Uma delas, o aumento da longevidade, vem requisitando políticas e programas sociais voltados à qualidade de vida, incluindo o âmbito do lazer. Este estudo qualitativo objetivou identificar aspectos emocionais na percepção de idosos, durante vivências no lazer. Os dados foram coletados por meio de questionário misto, aplicado a uma amostra de 20 participantes, de ambos os sexos. Foram analisados descritivamente pela Técnica de Análise de Conteúdo, revelando recorrências de crescimento positivo como a relação interpessoal e o respeito mútuo, a contemplação, a sensação de harmonia com a natureza, o elemento lúdico, entre outros, também responsáveis pelo vínculo afetivo do grupo. Conclui-se que experiências significativas no âmbito do lazer, capazes de contemplar a gama de necessidades e expectativas do homem, contribuem para a ressignificação emocional do lazer nesta fase do desenvolvimento.

O trabalho avaliou, em sementes de soja, as conseqüências qualitativas provenientes da secagem estacionária com distribuição radial de ar, variando o fluxo (26,9, 28,4 e 33,2 m³/minuto/t) e a temperatura do ar insuflado (42, 46 e 50ºC), considerando a posição das sementes na massa (17, 34 e 51 cm em relação ao cilindro de insuflação) e o tempo de secagem (0 a 12 horas, com intervalos de quatro horas). Para tanto, além das determinações das temperaturas e dos teores de água da massa, foi avaliado o desempenho fisiológico das sementes no início e ao final de seis meses de armazenamento. Apesar das vantagens físicas operacionais resultantes da combinação entre o fluxo e a temperatura intermediários (28,4 m³/minuto/t e 46ºC), a qualidade fisiológica foi menos prejudicada nas combinações dos menores fluxos (26,9 e 28,4 m³/minuto/t) com a maior temperatura (50ºC) e do maior fluxo (33,2 m³/minuto/t) com as menores temperaturas (42 e 46ºC); entre estas, levando em conta os aspectos físico-operacionais, a associação de 28,4 m³/minuto/t com 50ºC foi a mais eficiente na retirada de água das sementes. Assim, admitindo os intervalos de fluxo (26,9 a 33,2 m³/minuto/t) e de temperatura (42 a 50ºC) estudados, conclui-se que a elevação na temperatura demanda redução no fluxo e, inversamente, o aumento no fluxo demanda redução na temperatura.

Muitas espécies de Passiflora apresentam comportamento florífero diferente durante o ano e, consequentemente, com variações nas produções e períodos de colheitas, como observado para o maracujazeiro-amarelo (Passiflora edulis sims). Estudo com espécies silvestre constitui-se numa importante alternativa para usos de novos genótipos no melhoramento das espécies cultivadas comercialmente, em especial, a Passiflora setacea, devido ao grande potencial de mercado; contudo, essa espécie é pouco estudada, principalmente em relação à propagação, germinação, floração e condições de armazenamento. Assim, o objetivo deste trabalho foi avaliar o florescimento e a frutificação do maracujazeiro silvestre Passiflora setacea cultivado em Jaboticabal-SP. A floração e a frutificação foram avaliadas pelo percentual de frutificação através da polinização natural e artificial das flores, realizado no período de agosto a outubro. As características físicas dos frutos foram avaliadas através dos seguintes parâmetros: a) massa do fruto (g); b) diâmetro longitudinal do fruto (cm); c) diâmetro transversal do fruto (cm); d) espessura da casca (cm); e) rendimento de polpa (%). A característica química foi determinada por meio do teor de sólidos solúveis (SS). Verificou-se que a Passiflora setacea apresentou precocidade de floração em relação ao maracujazeiro-amarelo, com florescimento durante o ano todo, nas condições de Jaboticabal-SP. Observou-se que essa espécie possui bom nível de tolerância às doenças foliares, resistência à morte precoce e apresenta diferentes níveis de compatibilidade entre as plantas, possibilitando a essas características serem utilizadas em programas de melhoramento genético. Constatou-se ainda que as características físicas encontradas nos frutos atendem às exigências da indústria.

O objetivo deste estudo foi verificar os efeitos de uma intervenção conduzida com a mãe de uma criança com implante coclear através da avaliação de mudanças comportamentais identificadas após o programa. Participou deste estudo uma díade mãe ouvinte-criança com deficiência auditiva e implante coclear, filmada em quatro sessões de observação: uma situação de brinquedo e outra do cotidiano, antes e após a intervenção. Esta constou de dois encontros nos quais a mãe assistiu às filmagens e foi orientada quanto à sua conduta com relação à criança. Os resultados mostraram aumento no número de verbalizações maternas nas categorias informar e solicitar, bem como de falas da criança nas categorias falar espontaneamente e fazer solicitação, quando comparadas as medidas pré e pós-testes nas duas situações observadas. O estudo mostra a importância de intervenções que favoreçam a relação mãe-filho para o desenvolvimento de habilidades comunicativas da criança com deficiência auditiva e implante coclear.

The inappropriate use of antimicrobials in hospitals presents a negative impact on patient outcome and is associated with the emergence and spread of multidrug-resistant microorganisms. Antimicrobial stewardship programs (ASPs) have been instituted in order to improve the quality of prescriptions in hospitals. In this setting, the identification of patterns of inappropriate antimicrobial prescription is a valuable tool that allows ASPs to identify priorities for directing educative/restrictive policies. With this purpose, a study was conducted in the Bauru State Hospital, a teaching hospital with 285 beds affiliated to the Botucatu Medical School, São Paulo State University. The hospital maintains an active ASP since it was opened, in 2002. We selected 25% of the requests for parenteral antimicrobials (RPAs) from 2005 for analysis. Prescriptions for prophylactic purposes were excluded. All other RPAs were classified according to a modified Kunin and Jones categories. Univariate and multivariable analyses were performed to identify predictors of general inappropriateness and of specific prescription errors. Prescriptions classified as "appropriate'' or "probably appropriate" were selected as controls in all stages of the study. Among 963 RPAs included in our study, 34.6% were inappropriate. General predictors of inappropriateness were: prescription on weekends/holidays (OR = 1.67, 95% CI = 1.20-2.28, p = 0.002), patient from intensive care unit (OR = 1.57, 95% CI = 1.11-2.23, p = 0.01), peritoneal (OR = 2.15, 95% CI = 1.27-3.65, p = 0.004) or urinary tract infection (OR = 1.89, 95% CI = 1.25-2.87, p = 0.002), combined therapy with two or more antimicrobials (OR = 1.72, 95% CI = 1.15-2.57, p = 0.008) and prescriptions including penicillin (OR = 2.12, 95% CI = 1.39-3.25, p = 0.001) or first-generation cephalosporins (OR = 1.74, 95% CI = 1.01-3.00, p = 0.048). Previous consultation with an infectious diseases (ID) specialist had a protective effect against inappropriate prescription (OR = 0.34, 95% CI = 0.24-0.50, p < 0.001). Factors independently associated with specific prescription errors varied. However, consultation with an ID specialist was protective against both unnecessary antimicrobial use (OR = 0.04, 95% CI = 0.01-0.26, p = 0.001) and requests for agents with insufficient spectrum (OR = 0.14, 95% CI = 0.03-0.30, p = 0.01). In conclusion, the analysis of factors predictive of inappropriateness in antimicrobial prescription allowed us to identify issues requiring intervention. Also, it provided a positive feedback of the ASP efficacy, demonstrating the importance of previous consultation with an ID specialist to assure the quality of antimicrobial prescriptions.

Characteristics of speech, especially figures of speech, are used by specific communities or domains, and, in this way, reflect their identities through their choice of vocabulary. This topic should be an object of study in the context of knowledge representation once it deals with different contexts of production of documents. This study aims to explore the dimensions of the concepts of euphemism, dysphemism, and orthophemism, focusing on the latter with the goal of extracting a concept which can be included in discussions about subject analysis and indexing. Euphemism is used as an alternative to a non-preferred expression or as an alternative to an offensive attribution-to avoid potential offense taken by the listener or by other persons, for instance, pass away. Dysphemism, on the other hand, is used by speakers to talk about people and things that frustrate and annoy them-their choice of language indicates disapproval and the topic is therefore denigrated, humiliated, or degraded, for instance, kick the bucket. While euphemism tries to make something sound better, dysphemism tries to make something sound worse. Orthophemism (Allan and Burridge 2006) is also used as an alternative to expressions, but it is a preferred, formal, and direct language of expression when representing an object or a situation, for instance, die. This paper suggests that the comprehension and use of such concepts could support the following issues: possible contributions from linguistics and terminology to subject analysis as demonstrated by Talamo et al. (1992); decrease of polysemy and ambiguity of terms used to represent certain topics of documents; and construction and evaluation of indexing languages. The concept of orthophemism can also serves to support associative relationships in the context of subject analysis, indexing, and even information retrieval related to more specific requests.

Three-Phase Induction Motors (TIM) and Arc Welding Machines (AWM) are loads of special behavior widely used in industrial and commercial installations, and therefore may contribute significantly to the deterioration of the quality of energy supplied by utilities. This paper proposes a modeling in constant power of the unbalanced TIM starting using Genetic Algorithm (GA) and AWM short-circuit based on their statics characteristics curves. The proposed models are compared with the conventional models in the literature. The results showed the good performance of the proposed models, allowing a more precise analysis of the real requests of these loads.

The definition of models and base parameters for application of investigation tools in environment with high complexity are a basic premise to any sciences. The geophysics is a science with solid theoretical base and applications in diversified areas of the sciences geological, astronomical, meteorological, among many others. Its application in environmental studies is relatively recent and needs further research. To understand the behavior of resident contaminants in a dynamic and complex environment as the geological, it requests studies in scale laboratorial, under control of factors seasonality variable. This work simulates a leak of gasoline in soil, under conditions and in laboratory scale, with the objective of monitoring the temporary behavior of the hydrocarbon under the optics of variation of the parameter physical electric resistivity. The results indicate increase of the resistivity in recent periods the contamination, followed for stability in the values and finally fall and return tendency to the natural conditions.

The use of the Internet as a means of ensuring greater visibility for products, services and information offered by companies is gaining strength in recent decades. However, it is known that to ensure satisfaction and subsequent virtual customer loyalty, it is necessary to guarantee the quality of the websites, allowing indiscriminate access regardless of the resources used, as well as rapid responses to possible requests. In order to assist this process, this paper presents a set of guidelines for the development of websites having quality characteristics, efficiency and portability as per ISO 9126 norms. An observational analysis of e-commerce websites was done which showed that they are inadequate as to the proposed guidelines, making them difficult to access available content. Therefore, the adoption of the proposed guidelines can greatly contribute to increasing the quality of websites and, consequently, enable quick and effective access regardless of the resources used.
