Abstract In this article, we investigate the challenges faced by social service professionals in a changing society, increasingly complex and uncertain. Analyzing specific situations from a short-term ethnographic study, we aim to describe and interpret the various forms of knowledge expressed by professionals in their daily social interactions with their counterparts. We emphasize the growing relevance of practical wisdom in tackling unforeseen circumstances. By examining the crossroads between abstract knowledge and concrete application, we identify strategies to address the challenges inherent in shifting social dynamics. Moreover, we highlight the importance of comprehending implicit knowledge in day-to-day professional interactions.

Resumo Neste artigo investigamos os desafios enfrentados por profissionais de serviços sociais, numa sociedade em mudança, cada vez mais complexa e incerta. Analisando situações específicas ocorridas num estudo etnográfico de curta duração, procuramos descrever e interpretar os vários saberes expressos por profissionais na interação social quotidiana com os seus interlocutores e destacamos a crescente relevância da sabedoria prática para enfrentar situações imprevisíveis. Ao examinarmos a interseção entre o conhecimento abstrato e a sua aplicação concreta, identificamos estratégias para abordar os desafios inerentes às dinâmicas sociais mutáveis e sublinhamos a importância de compreender o conhecimento implícito nas interações profissionais diárias.

Abstract The potential of daylight harvesting is related to the building location. However, climatic zonings adopted by energy efficiency programs focus only on the thermal performance, neglecting important variables of the buildings’ luminous performance. This paper aims to investigate the relationship between the angle of solar incidence, the annual occurrence of clear sky, and the annual lighting energy consumption when daylight harvesting is practiced. The lighting consumption of a square floor space, orientated in the cardinal directions, was simulated for 20 Brazilian cities. The frequency of the 15 CIE sky types was determined for each city using weather files and the angle of solar incidence was calculated for each hour of the year. The analysis comprised graphical exploration, Pearson's correlation, and multiple regression. The sensitivity of the consumption to the other two variables could be perceived in the hourly but not the annual analysis. The correlation between annual consumption and latitude was more robust for the intertropical range, with increased consumption moving south, and varied significantly for each orientation. It was concluded that, although relevant, the variables are not representative of variations in annual lighting consumption for application in climate zoning.

O aproveitamento da luz natural está relacionado à localização do edifício. Tadavia, os zoneamentos climáticos dos programas de eficiência energética focam no desempenho térmico, negligenciando importantes variáveis do desempenho luminoso das edificações. Este trabalho objetivou investigar a relação entre o ângulo de incidência solar, a ocorrência anual de céu claro e o consumo anual de iluminação, considerando o aproveitamento da luz natural. Simulou-se o consumo de iluminação de um ambiente quadrado, orientado aos pontos cardeais, para 20 cidades brasileiras. Determinou-se a frequência dos 15 tipos de céu CIE para cada cidade, usando-se arquivos climáticos, e calculou-se o ângulo de incidência solar para cada hora do ano. A análise compreendeu exploração gráfica, correlação de Pearson e regressão múltipla. A sensibilidade do consumo às outras duas variáveis pode ser percebida na análise horária, mas não na anual. A correlação entre consumo anual e latitude foi mais robusta para a faixa intertropical, com o consumo aumentando para o sul, e variando significativamente para cada orientação. Concluiu-se que, embora relevantes, as variáveis não são representativas das variações de consumo anual de iluminação para aplicação em zoneamentos climáticos.

RESUMO: O estado de Santa Catarina é o segundo maior produtor de sementes de arroz do Brasil. As pesquisas com bactérias fitopatogênicas nesta cultura são escassas e a alta frequência de doenças da panícula leva à hipótese de que sementes podem estar infectadas por bactérias. O objetivo desta pesquisa foi quantificar a incidência de bactérias nas sementes, verificar a viabilidade das bactérias durante o período de armazenamento e caracterizar as bactérias associadas. Foram analisadas sementes das safras 2018/19 e 2019/20. Para verificar a incidência, as sementes foram desinfestadas, plaqueadas em meio de cultura ágar nutriente + fungicida e incubadas por sete dias a 27 °C. Para avaliar a viabilidade, a cada 45 dias, três cultivares armazenadas em uma unidade de beneficiamento foram submetidas à mesma metodologia de detecção. Para caracterizar, colônias prevalentes foram isoladas em meio de cultura semisseletivo Pantoea genus-specific ágar (PGSA), onde as que apresentaram crescimento foram submetidas à extração do ácido desoxirribonucléico (DNA) e Reação em Cadeia da Polimerase (PCR), sequenciamento do DNA e comparação de sequências no GenBank. A reação de hipersensibilidade (HR) em tabaco foi realizada utilizando uma suspensão bacteriana de cada isolado. Todas as amostras de sementes apresentaram incidência média de 83%. Durante o armazenamento, as sementes mantiveram viabilidade bacteriana estável, com incidência média de 95% no início do armazenamento e 99% ao fim. Todos os isolados que cresceram no meio de cultura PGSA, foram identificados por caracterização molecular com 100% de identidade com dois espécimes de Pantoea ananatis e um deles induziu HR em tabaco.

ABSTRACT: The state of Santa Catarina is the second-largest producer of rice seeds in Brazil. Research on phytopathogenicbacterias in this crop is scarce and the high frequency of panicle diseases leads to the hypothesis that seeds may be infected by bacteria. This research quantified the incidence of bacteria in the seeds, verified the bacteria viability during the storage period and characterized the associated bacteria. Seeds from the 2018/19 and 2019/20 seasons were analyzed. To check the incidence, the seeds were disinfected, plated on a nutrient agar + fungicide culture medium, and incubated for seven days at 27 °C. To assess viability, every 45 days, three cultivars stored in a processing unit were subjected to the same detection methodology. To characterize, prevalent colonies were isolated on semi-selective culture medium Pantoea genus-specific agar (PGSA), where the ones that showed growth were subjected to deoxyribonucleic acid (DNA) extraction and Polymerase Chain Reaction (PCR), DNA sequencing, and sequence comparison on GenBank. The hypersensitivity reaction (HR) in tobacco was performed using a bacterial suspension of each isolate. All seed samples had an average incidence of 83%. During storage, the seeds maintained stable bacterial viability, with an average incidence of 95% at the beginning of storage and 99% at the end of it. All isolates that grew in PGSA culture medium were identified by molecular characterization with 100% identity with two specimens of Pantoeaananatis and one of them induced RH in tobacco.

ABSTRACT Objective: Cervical traumatic neuromas (CTNs) may appear after lateral neck dissection for metastatic thyroid carcinoma. If they are misdiagnosed as metastatic lymph nodes (LNs) in follow-up neck ultrasound (US), unnecessary and uncomfortable fine-needle aspiration biopsy are indicated. The present study aimed to describe US features of CTNs and to assess the US performance in distinguishing CTNs from abnormal LNs. Subjects and methods: Retrospective evaluation of neck US images of 206 consecutive patients who had lateral neck dissection as a part of thyroid cancer treatment to assess CTN’s US features. Diagnostic accuracy study to evaluate US performance in distinguishing CTNs from abnormal LNs was performed. Results: Eight-six lateral neck nodules were selected for analysis: 38 CTNs and 48 abnormal LNs. CTNs with diagnostic cytology were predominantly hypoechogenic (100% vs. 45%; P = 0.008) and had shorter diameters than inconclusive cytology CTNs: short axis (0.39 cm vs. 0.50 cm; P = 0.03) and long axis (1.64 cm vs. 2.35 cm; P = 0.021). The US features with the best accuracy to distinguish CTNs from abnormal LNs were continuity with a nervous structure, hypoechogenic internal lines, short/long axis ratio ≤ 0.42, absent Doppler vascularization, fusiform morphology, and short axis ≤ 0.48 cm. Conclusion: US is a very useful method for assessing CTNs, with good performance in distinguishing CTNs from abnormal LNs.

ABSTRACT Purpose: To study the uptake capacity of cells from the reticuloendothelial system after irradiation with high-energy X-rays. Methods: Eighteen male Wistar rats were distributed in three groups: group A (n = 6): control, unirradiated animals studied alongside animals from group B; group B (n = 6) and group C (n = 6): animals irradiated and studied after 24 and 48 hours, respectively. The rats were anesthetized and placed on a 10 MV linear accelerator. Next, they were irradiated in the abdominal region, with 8 Gy. Twenty-four (groups A and B) and 48 hours later (group C), a colloidal carbon solution (1 mL/kg) was intravenously injected in the tail vein. Fifty minutes later, the spleens and livers were withdrawn and prepared to be studied. Kupffer cells and splenic macrophages containing carbon pigments were counted in an optical microscope. Arithmetic means were calculated for each group and compared among them. Results: X-rays were associated with a reduced number of Kupffer cells containing colloidal carbon, proliferation and enlargement of biliary ducts, hypoplasia, and hepatocyte necrosis. In the irradiated spleen, the colloidal carbon uptake was concentrated in the marginal zone around the white pulp, with an inexpressive uptake of pigments by macrophages from white and red pulps. Conclusions: The X-rays in the rat abdomen are associated with a reduction in the Kupffer cells uptake of colloidal carbon, hepatocyte disorders, bile duct proliferation, and splenic uptake of colloidal carbon concentrated in the marginal zone.

Abstract Scaphoid fractures account for 50 to 70% of all carpal bone fractures. Percutaneous scaphoid osteosynthesis can use the dorsal or volar approach, both with good results, and is most commonly performed under general anesthesia or regional nerve block. The wide-awake local anesthesia no tourniquet (WALANT) technique is already considered a safe and cost-effective technique in hand surgery around the world. Local anesthesia with epinephrine causes vasoconstriction, which obviates the need for tourniquet and, consequently, the need to use patient sedation. Thus, the possibility of testing fixation stability under physiological forces is another great advantage of using local anesthesia. In the technique described in the present paper, active wrist and hand motion can be tested immediately after scaphoid fixation. Wide-awake local anesthesia no tourniquet has been increasingly used in soft-tissue hand surgery and in the fixation of metacarpal and phalangeal fractures. However, to date, there is no published literature addressing the use of this technique in percutaneous scaphoid osteosynthesis. The purpose of the present technical note is to describe the use of WALANT for both the dorsal and volar approaches in percutaneous scaphoid osteosynthesis.

Resumo As fraturas do escafoide representam entre 50 e 70% de todas as fraturas dos ossos do carpo. A osteossíntese percutânea do escafoide pode usar a abordagem dorsal ou volar, ambas com bons resultados. É mais comumente realizada sob anestesia geral ou bloqueio nervoso regional. A técnica de anestesia local com o paciente totalmente acordado e sem torniquete (WALANT, na sigla em inglês) já é considerada uma técnica segura e eficaz na cirurgia da mão. A anestesia local com epinefrina causa vasoconstrição, o que evita o uso de torniquete e, consequentemente, a necessidade de sedação do paciente. Assim, a possibilidade de testar a estabilidade da fixação sob forças fisiológicas é outra grande vantagem do uso da anestesia local. Na técnica descrita aqui, o movimento ativo do punho e da mão pode ser testado imediatamente após a fixação escafoide. A técnica WALANT tem sido cada vez mais utilizada na cirurgia da mão em partes moles e na fixação de fraturas de metacarpo e falanges. No entanto, até o momento, não há literatura publicada abordando o uso dessa técnica na osteossíntese percutânea do escafoide. O objetivo desta nota técnica é descrever o uso de WALANT tanto para a abordagem dorsal quanto volar na osteossíntese percutânea do escafoide.

Resumo O objetivo deste estudo foi descrever a prevalência de participação esportiva em crianças e adolescentes brasileiros por meio de uma revisão sistemática de literatura. A busca foi realizada nas seguintes bases de dados eletrônicas: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO e SCOPUS de manuscritos publicados até o ano de 2020, por meio da combinação das palavras-chave: “crianças”, “adolescentes”, “prevalência” e “participação esportiva”, em português e inglês. Foram incluídos na revisão 26 artigos publicados no período de 2003 a 2020, com objetivo de estimar a prevalência de crianças e adolescentes brasileiros acerca da participação em esportes organizados. Quanto a região de realização do estudo, a maioria foi desenvolvido no sul (57.7%; n=15), seguido do sudeste (19.2%; n=05) e nordeste (15.4; n=04), além de 7.7% (n=02) em todas as regiões do país. Os dados mostraram prevalências de participação esportiva que variaram entre 15.0% a 73.2% (média de 44.8%) entre crianças e adolescentes, sendo superior no sexo masculino (63.1%). A partir dos resultados encontrados evidencia-se a necessidade do desenvolvimento de políticas públicas para favorecera aderência e manutenção de jovens para a prática esportiva, principalmente entre aqueles do sexo feminino.

Abstract The aim of this study is to describe the prevalence of sports participation in Brazilian children and adolescents through a systematic literature review. A search was carried out in the following electronic databases: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO, and SCOPUS for manuscripts published until 2020, combining the keywords: “children”, “adolescents”, “prevalence”, and “sports participation”, in Portuguese and English. Twenty-six articles published between 2003 and 2020 were included in the review, with the aim of estimating the prevalence of participation in organized sports in Brazilian children and adolescents. Considering the regions where the studies were carried out, the majority were developed in the south (57.7%; n=15), followed by the southeast (19.2%; n=05), and northeast (15.4%; n=04), in addition to 7.7% (n=02) in all regions of the country. The data showed prevalence of sports participation ranging from 15.0% to 73.2% (mean of 44.8%) among children and adolescents, being higher in males (63.1%). From the results found, the need to develop public policies is evident, in order to favor adherence and maintenance of young people to sports practice, especially among those of the female sex.

RESUMO Introdução: Durante o tratamento ortodôntico, muitos pacientes solicitam, também, alteração na cor dos seus dentes. Objetivo: O presente estudo avaliou diferentes produtos clareadores e branqueadores, quanto à sua eficácia sob os braquetes ortodônticos. Métodos: 70 incisivos bovinos foram aleatoriamente divididos em cinco grupos (n = 14): C) dentifrício não branqueador (controle); WTsi) dentifrício branqueador com sílica hidratada; WThp) dentifrício branqueador com peróxido de hidrogênio a 2%; OB) clareamento no consultório e HB) clareamento caseiro. Usando um espectrofotômetro Easyshade, foram avaliadas duas áreas na superfície vestibular dos dentes: sob o braquete (experimental) e ao redor do braquete (controle). Para análise estatística, foram usados os testest pareado, ANOVA e Tukey. Resultados: As comparações intragrupos demonstraram que, nos grupos C, WThp e HB, ocorreram diferenças estatisticamente significativas nas alterações de cor do esmalte (ΔEab) entre as áreas sob o braquete e ao redor do braquete (C: sob o braquete = 7,97 ± 2,35, ao redor do braquete = 2,86 ± 0,81, p< 0,01; WThp: sob o braquete = 4,69 ± 2,98, ao redor do braquete = 2,05 ± 1,41, p< 0,01; HB: sob o braquete = 7,41 ± 2,89, ao redor do braquete = 9,86 ± 3,32, p= 0,02). Os grupos WTsi, OB e HB demonstraram semelhanças na percepção do clareamento (ΔWID) entre as áreas avaliadas. As comparações intergrupos demonstraram que, nas áreas sob os braquetes, as alterações de cor (ΔEab) foram semelhantes para os grupos, com exceção do WThp (C = 7,97 ± 2,35; WTsi = 8,54 ± 3,63; WThp = 4,69 ± 2,98; OB = 9,31 ± 4,32; HB = 7,41 ± 2,89; p< 0,01). Conclusões: As alterações na cor dos dentes foram efetivas para os procedimentos testados nos grupos WTsi, OB e HB na presença de braquetes metálicos ortodônticos.

ABSTRACT Introduction: Many patients wearing orthodontic appliances request alterations in the shade of their teeth during orthodontic treatment. Objective: This study aimed to evaluate the efficacy of different products for bleaching and whitening under orthodontic brackets. Methods: Seventy bovine incisors were randomly divided into five groups (n = 14): C) non-whitening toothpaste (control); WTsi) hydrated silica whitening toothpaste; WThp) 2% hydrogen peroxide whitening toothpaste; OB) in-office bleaching; and HB) at-home bleaching. Two buccal surface areas were evaluated using the Easyshade spectrophotometer: under the metal bracket (experimental) and around the bracket (control). The paired t-test, ANOVA, and Tukey tests were applied for statistical analysis. Results: Intragroup comparisons showed that in groups C, WThp and HB, there were statistically significant differences in the enamel color changes (ΔEab) between under and around the bracket areas (C - under bracket = 7.97 ± 2.35, around bracket = 2.86 ± 0.81, p< 0.01; WThp - under bracket = 4.69 ± 2.98, around bracket = 2.05 ± 1.41, p< 0.01; HB - under bracket = 7.41 ± 2.89, around bracket: 9.86 ± 3.32, p= 0.02). Groups WTsi, OB and HB presented similar perception of tooth whiteness (ΔWID) between the tested areas. Intergroup comparisons demonstrated that under the bracket area, the color change (ΔEab) was similar for all groups, except WThp (C = 7.97 ± 2.35; WTsi = 8.54 ± 3.63; WThp = 4.69 ± 2.98; OB = 9.31 ± 4.32; HB = 7.41 ± 2.89; p< 0.01). Conclusions: The dental color changes were effective for the products tested in groups WTsi, OB and HB in the presence of metallic orthodontic brackets.

Resumo Objetivo A maioria dos programas de triagem pré-natal para toxoplasmose utiliza imunoensaios em amostras de soro de gestantes. Poucos estudos avaliam a acurácia dos testes de triagem em amostras de sangue seco, que são de fácil coleta, armazenamento e transporte. Este estudo teve como objetivo determinar o desempenho e avaliar a concordância entre um imunoensaio em sangue seco e um teste de referência em soro de gestantes de um programa de rastreamento pré-natal de base populacional para toxoplasmose no Brasil. Métodos Realizou-se um estudo transversal para comparar os imunoensaios Imunoscreen Toxoplasmose IgM e Imunoscreen Toxoplasmose IgG (Mbiolog Diagnósticos, Ltda., Contagem, Minas Gerais, Brazil) em sangue seco com o padrão de referência ensaio fluorescente ligado a enzimas (enzyme-linked fluorescent assay, ELFA, BioMérieux S.A., Lion, França) no soro de gestantes do Programa de Controle de Toxoplasmose Congênita de Minas Gerais. Resultados O exame em sangue seco foi capaz de discriminar os resultados positivos e negativos das gestantes quando comparado ao teste de referência, com acurácia de 98,2% para imunoglobulina G (IgG), e de 95,8% para imunoglobulina M (IgM). Conclusão O sangue seco apresenta bom desempenho e é uma amostra de fácil coleta, armazenamento e transporte, o que o torna um método promissor para programas de triagem pré-natal de toxoplasmose em países com dimensões continentais, recursos limitados, e alta prevalência de toxoplasmose, como é o caso do Brasil.

Abstract Objective Most prenatal screening programs for toxoplasmosis use immunoassays in serum samples of pregnant women. Few studies assess the accuracy of screening tests in dried blood spots, which are of easy collection, storage, and transportation. The goals of the present study are to determine the performance and evaluate the agreement between an immunoassay of dried blood spots and a reference test in the serum of pregnant women from a population-based prenatal screening program for toxoplasmosis in Brazil. Methods A cross-sectional study was performed to compare the immunoassays Imunoscreen Toxoplasmose IgM and Imunoscreen Toxoplasmose IgG (Mbiolog Diagnósticos, Ltda., Contagem, Minas Gerais, Brazil)in dried blood spots with the enzymelinked fluorescent assay (ELFA, BioMérieux S.A., Lyon, France) reference standard in the serum of pregnant women from Minas Gerais Congenital Toxoplasmosis Control Program. Results The dried blood spot test was able to discriminate positive and negative results of pregnant women when comparedwith the reference test, with an accuracy of 98.2% for immunoglobulin G (IgG), and of 95.8% for immunoglobulin M (IgM). Conclusion Dried blood samples are easy to collect, store, and transport, and they have a good performance,making this a promisingmethod for prenatal toxoplasmosis screening programs in countries with continental dimensions, limited resources, and a high prevalence of toxoplasmosis, as is the case of Brazil.

ABSTRACT Introduction: Antineutrophil cytoplasmic autoantibodies (ANCAs) are crucial in the pathogenesis of ANCA-associated glomerulonephritis. Although highly specific for this disease, these antibodies can appear in healthy individuals or occur in other settings such as malignance, other inflammatory disease, or drugs. Renal biopsy remains essential for diagnosis and as a prognostic tool. Failing to perform a biopsy risks an incomplete evaluation or misdiagnosis. Clinical case: A 60-year-old male known to have had previous normal kidney function was admitted with generalized pitting edema, nonpruritic erythematous rash, and decreased urine output. He had been recently started on clozapine for depression. Laboratory tests revealed nephrotic syndrome with massive proteinuria (11g/day), hematuria and elevated serum creatinine that reached a maximum of 4.9 mg/dl. The only positive finding was a high titer of myeloperoxidase (MPO) ANCA antibody (111 UI/ml). Clozapine was discontinued, and he was started on conservative management of the nephrotic syndrome. The rash disappeared within one week. Kidney biopsy showed cellular variant focal segmental glomerulosclerosis (FSGS) with mild acute tubular injury. The patient was treated with oral prednisolone with complete remission. Repeat MPO-ANCA was negative after one month. Discussion: We present a challenging case that highlights the importance of kidney biopsy for accurate diagnosis with major impact on treatment and prognosis. This case also underlines the presentation and evolution of FSGS cellular variant, a rare and poorly understood disease. The relationship between skin rash with high MPO titer and the administration of clozapine with clinical remission after its discontinuation favors the hypothesis of drug associated ANCA-vasculitis.

Resumo Quantificar e caracterizar a percepção do brilho na atividade visual ainda é um desafio nas pesquisas, por se tratar de um parâmetro relativo à posição ativa do ocupante. O objetivo desta pesquisa foi considerar o usuário dinâmico em ambientes de trabalho, verificando a influência do tempo de visualização e da direção do olhar na redução da probabilidade de ofuscamento. Os dados foram levantados em um ambiente real com 26 participantes, monitorados enquanto realizaram atividades comuns em escritórios. As movimentações do olhar foram registradas usando óculos eye-tracker. Através de imagens high dynamic range (HDR) foram mapeados os brilhos das superfícies e obtida a probabilidade de ofuscamento (DGP). Esses dados foram correlacionados com as respostas de satisfação dos usuários, obtida por meio de questionários. Constatou-se que, ao realizar uma tarefa, o usuário mantém seu olhar fixo no plano de trabalho e, durante períodos de pausa, o olhar tornou-se mais disperso. As aberturas foram visualizadas, principalmente, quando localizadas no plano de fundo da tarefa ou quando suas luminâncias foram menores. Concluiu-se que os valores de DGP ponderado estiveram mais próximos dos votos de satisfação manifestados pelos participantes, ressaltando a importância de considerar as direções de visão e o tempo de visualização nesta avaliação.

Abstract To quantify and characterise the perception of brightness in visual activity is still a challenge for researchers, mainly because it is a subjective parameter, dependent on the active position of the occupant. The aim of this study was to consider dynamic users in work environments and verify the influence of viewing time and sight direction on glare probability. The data were collected in a real environment where 26 volunteers were monitored while performing common office tasks. The gaze movements were recorded with an Eye-Tracker device. Through High Dynamic Range (HDR) images the surfaces’ brightnesses were mapped and the glare probability index (DGP) was calculated. Those data were correlated with the users' satisfaction answers obtained through questionnaires. The researchers found that, when performing a task, users keep their eyes fixed on the task surface, and during break periods, the sight became more dispersed. The windows were mainly visualised when they were part of the task’s background or when their luminance values were low. The conclusion was that DGP weighted values were closer to the satisfaction votes expressed by the participants, emphasising the importance of considering vision directions and viewing time in this analysis.

Resumo Este estudo trata sobre o acionamento da iluminação artificial e das persianas em função da percepção da iluminação do indivíduo/observador quando este se encontra na porta de entrada de uma sala. O objetivo do trabalho foi relacionar a percepção da iluminação, o acionamento das lâmpadas e das persianas. A metodologia consistiu na aquisição de dados experimentais por meio de imagem HDR e de questionários aplicados em 41 participantes. As variáveis analisadas foram a luminância média da janela (Lja) e os índices de ofuscamento DGP e DGI, pois elas estavam correlacionadas com a percepção da iluminação, o acionamento das lâmpadas e das persianas. O índice DGP se mostrou pouco sensível ao subestimar valores frente a situações evidentes de ofuscamento. Para o DGI, o intervalo definido para a situação de lâmpadas desligadas e persianas abertas foi entre 18,4 ± 1,0 e 23,8 ± 1,0, quando a percepção da iluminação da sala foi considerada “clara”. Para Lja, o intervalo para a situação de lâmpadas desligadas e de persianas abertas foi entre 1.636 ± 302 cd/m² a 4.981 ± 419 cd/m². Conclui-se que os intervalos podem servir de base para construção de modelos comportamentais a serem usados em simulações computacionais para estudar o consumo de energia elétrica nas edificações e para auxiliar o desenvolvimento de projetos de arquitetura visando o aproveitamento da luz natural.

Abstract This article considers that visual perception influences the switching on electric lighting and blinds closing. The objective is to study the relationship of visual perception from the door position, with the switching on electric lighting and with the blinds down position. The methodology consisted of experiments conducted with 41 participants to inquire about their visual perception, and switch light on and blinds closing events data. By using an HDR image technique, the mean window luminance (Lja), DGP and DGI were analyzed because of their correlation with the visual perception, the switching lighting on and the blinds down position. The DGP index presented little sensitivity because of their values that did not demonstrate apparent visual discomfort situations. For the DGI, the range set for the situation of the lighting off and blinds opened was between 18.4 ± 1.0 and 23.8 ± 1.0, and the visual perception of the room is "bright". To mean window luminance (Lja), between 1636 ± 302 cd/m² and 4981 ± 419 cd/m², the lighting was off, and the blinds opened. The conclusion is that the proposed intervals of DGI and the mean window luminance can be used to construct behavioral models to support the electric energy use simulation in buildings and to enhance the daylight design of interior space.

Abstract Introduction: a survey on peri-operative nutritional support in pancreatic and biliary surgery among Spanish hospitals in 2007 showed that few surgical groups followed the 2006 ESPEN guidelines. Ten years later we sent a questionnaire to check the current situation. Methods: a questionnaire with 21 items sent to 38 centers, related to fasting time before and after surgery, nutritional screening use and type, time and type of peri-operative nutritional support, and number of procedures. Results: thirty-four institutions responded. The median number of pancreatic resections (head/total) was 29.5 (95 % CI: 23.0-35; range, 5-68) (total, 1002); of surgeries for biliary malignancies (non-pancreatic), 9.8 (95 % CI: 7.3-12.4; range, 2-30); and of main biliary resections for benign conditions, 10.4 (95 % CI: 7.6-13.3; range, 2-33). Before surgery, only 41.2 % of the sites used nutritional support (< 50 % used any nutritional screening procedure). The mean duration of preoperative fasting for solid foods was 9.3 h (range, 6-24 h); it was 6.6 h for liquids (range, 2-12). Following pancreatic surgery, 29.4 % tried to use early oral feeding, but 88.2 % of the surveyed teams used some nutritional support; 26.5 % of respondents used TPN in 100 % of cases. Different percentages of TPN and EN were used in the other centers. In malignant biliary surgery, 22.6 % used TPN always, and EN in 19.3 % of cases. Conclusions: TPN is the commonest nutrition approach after pancreatic head surgery. Only 29.4 % of the units used early oral feeding, and 32.3 % used EN; 22.6 % used TPN regularly after surgery for malignant biliary tumours. The 2006 ESPEN guideline recommendations are not regularly followed 12 years after their publication in our country.

Resumen Introducción: realizamos una encuesta sobre soporte nutricional perioperatorio en cirugía pancreática y biliar en hospitales españoles en 2007, que mostró que pocos grupos quirúrgicos seguían las guías de ESPEN 2006. Diez años después enviamos un cuestionario para comprobar la situación actual. Métodos: treinta y ocho centros recibieron un cuestionario con 21 preguntas sobre tiempo de ayunas antes y después de la cirugía, cribado nutricional, duración y tipo de soporte nutricional perioperatorio, y número de procedimientos. Resultados: respondieron 34 grupos. La mediana de pancreatectomías (cabeza/total) fue de 29,5 (IC 95 %: 23,0-35; rango, 5-68) (total, 1002), la de cirugías biliares malignas de 9,8 (IC 95 %: 7,3-12,4; rango, 2-30) y la de resecciones biliares por patología benigna de 10,4 (IC 95 %: 7,6-13,3; rango, 2-33). Solo el 41,2 % de los grupos utilizaban soporte nutricional antes de la cirugía (< 50 % habian efectuado un cribado nutricional). El tiempo medio de ayuno preoperatorio para sólidos fue de 9,3 h (rango, 6-24 h), y de 6,6 h para líquidos (rango, 2-12). Tras la pancreatectomía, el 29,4 % habían intentado administrar una dieta oral precoz, pero el 88,2 % de los grupos usaron algún tipo de soporte nutricional y el 26,5 % usaron NP en el 100 % de los casos. Los demás grupos usaron diferentes porcentajes de NP y NE en sus casos. En la cirugía biliar maligna, el 22,6 % utilizaron NP siempre y NE en el 19,3 % de los casos. Conclusiones: la NP es el soporte nutricional más utilizado tras la cirugía de cabeza pancreática. Solo el 29,4 % de las unidades usan nutrición oral precoz y el 32,3 % emplean la NE tras este tipo de cirugía. El 22,6 % de las instituciones usan NP habitualmente tras la cirugía de tumores biliares malignos. Las guías ESPEN 2006 no se siguen de forma habitual en nuestro país tras más de 10 años desde su publicación.

Resumo Este artigo discute formatos desejáveis para um plano nacional de capacitação financeira, a partir da experiência brasileira. As propostas convencionais usualmente dão excessiva importância à educação financeira, sob justificativa de que a transferência de conhecimento e informação é a melhor forma de promover alfabetização, capacitação e bem-estar financeiro. A análise crítica desta proposta mostra, porém, que ela é inadequada, pois: i) é imperativo incluir o ambiente em que as decisões financeiras são tomadas e; ii) a qualificação financeira não pode se dar prioritariamente via transferência de conhecimento, mas pelo aconselhamento financeiro provido por especialistas independentes.

Abstract This paper discusses desirable formats for a financial capability plan from the perspective of the Brazilian experience. The conventional proposal has usually been to much focused on financial education, arguing that transfer of knowledge and information is the best way to promote financial literacy, financial capability and well-being. However, the critical analysis of this proposal shows that it is inadequate because: (i) the treatment must deal with the environment in which financial decisions are taken, and; (ii) financial qualification can not be achieved through primary education, but through financial advice provided by independent experts.
