RESUMO O objetivo deste estudo foi comparar o desenvolvimento de dois clones de eucalipto sob a influência ou não da entrada precoce dos animais em sistema silvipastoril em Capixaba, Acre. O clima da região é AWI, com precipitação anual entre 1.680 a 2.580 mm, com estação seca entre maio e setembro. O delineamento foi inteiramente casualizado em esquema fatorial 2 x 2 com seis repetições e quatro tratamentos: a) Clone I144 com acesso do gado aos 9 meses (TR1); b) Clone I144 sem acesso do gado aos 9 meses (TR2); c) Clone VM01 com acesso do gado aos 9 meses (TR3); e d) Clone VM01 sem acesso do gado aos 9 meses (TR4). Os dados foram coletados das 16 árvores centrais de cada parcela, aos 9, 12, 19, 24, 32 e 36 meses de idade. Realizou-se a medição de altura total (HT), diâmetro à altura do peito (DAP) e o volume individual com casca de cada fuste para cada clone foi obtido por meio de cubagem rigorosa. Foram geradas curvas de crescimento em função da idade para HT, DAP e Volume por ha, utilizando o modelo Logístico. O clone VM01 apresentou maior sobrevivência, diâmetro e volume por ha em comparação ao clone I144, com maiores valores destas variáveis para o tratamento que não teve a entrada precoce dos animais. O Clone VM01 apresentou estimativas de produção máxima de volume por hectare 83,8% superior ao do clone I144. A entrada precoce dos animais no sistema silvipastoril influenciou negativamente o crescimento e a sobrevivência dos clones de eucalipto.

ABSTRACT This study aimed to compare the development of two eucalyptus clones under the influence or not of the early animal entry into a silvopastoral system in Capixaba, Acre. The region's climate is AWI, with annual rainfall between 1,680 and 2,580 mm and a dry season between May and September. The design was entirely randomized in a 2 x 2 factorial scheme with six replications and four treatments: a) Clone I144 with cattle access at nine months (TR1); b) Clone I144 without cattle access at nine months (TR2); c) Clone VM01 with cattle access at nine months (TR3); and d) Clone VM01 without cattle access at nine months (TR4). Data was collected from the 16 central trees of each plot at 9, 12, 19, 24, 32, and 36 months of age. Total height (TH) and diameter at breast height (DBH) were measured, and the individual volume with bark from each stem per clone was obtained by rigorous cubing. Growth curves were generated as a function of age for HT, DBH, and Volume per ha using the Logistic model. Clone VM01 displayed higher survival, diameter, and volume per ha than clone I144, with higher values for these variables for the treatment without early animal entry. Clone VM01 demonstrated estimates of maximum production volume per hectare 83.8% higher than clone I144. The early animal entry into the silvopastoral system negatively influenced the growth and survival of the eucalyptus clones.

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.

Métodos: o protocolo seguirá o método proposto pelo Joanna Briggs Institute e as diretrizes PRISMA-P para relato de protocolos de revisão. A busca será feita na MEDLINE, Cochrane Library, Embase, Web of Science, Scopus, CINAHL e literatura cinzenta. Uma estratégia de busca foi desenvolvida para a MEDLINE, que será adaptada para cada base de dados. Dois revisores independentes rastrearão os artigos pelo título e resumo. Em seguida, farão a leitura do texto completo dos artigos incluídos, considerando os critérios de elegibilidade. Os dados serão extraídos com um formulário padronizado. Os resultados serão apresentados em fluxograma e resumo narrativo, seguindo as diretrizes do PRISMA-ScR. Revisão da literatura: há escassez de pesquisas que descrevam métodos de treinamento perceptivo-visual para analisar parâmetros da VED e dados inconsistentes para orientar a tomada de decisão clínica. Esta revisão fornecerá informações abrangentes sobre o desenvolvimento de treinamento para esse tipo de análise. Conclusão: este protocolo de revisão de escopo apresentará o estado geral das pesquisas sobre o tema e identificará as lacunas existentes na base de evidências.

ABSTRACT Purpose: to present a scoping review protocol to identify and map available evidence on training for fiberoptic endoscopic evaluation of swallowing parameter analysis. Methods: the protocol follows the method proposed by the Joanna Briggs Institute and the PRISMA-P guidelines for review protocol reports. The survey will be made in MEDLINE, Cochrane Library, Embase, Web of Science, Scopus, CINAHL, and grey literature. A search strategy has been developed for MEDLINE, which will be adapted for each database. Two independent reviewers will screen the articles by title and abstract. Then, they will read the full text of the included articles, considering the eligibility criteria. The data will be extracted with a standardized form. The results will be presented in a flowchart and narrative summary, following the PRISMA-ScR guidelines. Literature Review: there is a scarcity of research describing visual-perceptual training methods to analyze FEES parameters and inconsistent data to guide clinical decision-making. This review will provide comprehensive information on developing training for this type of analysis. Conclusion: this scoping review protocol will present the overall state of research on the topic and identify existing gaps in the base of evidence.

ABSTRACT The present study aimed to estimate genetic parameters of 20 common bean genotypes, commercial and regional bean on weed interference. The agronomic characters analyzed were: average stem diameter (ASD); average plant length (APL); number of pods per pot (NPP); number of locules per pod (NLP); number of grains per pod (NGP); percentage of empty locules (% EL); total grains per pot (TGP); total grain weight per pot (TGW) and average grain weight (AGW). High heritability values were found for most of the characters studied, except for NGP and EL; in addition to great genetic variability among genotypes. Therefore, for most of the characteristics of agronomic interest studied, simple selection methods can be applied with great potential to identify superior genotypes and consequent genetic progress in common bean breeding.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

RESUMO Objetivo: O objetivo deste trabalho foi analisar a microbiota bacteriana e fúngica encontrada em estojos de lentes de contato em dois grupos, correlacionar os dados sobre os hábitos de uso de lentes de contato e avaliar se há diferença na positividade das culturas entre os usuários estojos de lentes de contato com ranhuras e sem ranhuras. Métodos: Dois grupos foram formados, trabalhadores do hospital e pessoas que não visitaram o hospital (35 indivíduos por grupo), e um questionário foi aplicado sobre dados epidemiológicos e hábitos relacionados ao uso de lentes de contato e estojos de lentes. Além disso, 140 amostras, coletadas do compartimento direito e esquerdo de cada estojo de lente, esfregando o fundo dos mesmos, foram testadas por bacterioscopia e por culturas de fungos e bactérias, com identificação computadorizada da espécie. Resultados: Não houve crescimento fúngico em nenhum dos 70 estojos de lentes de contato, porém bactérias foram encontradas em 39; não houve diferença estatística entre os grupos. A maioria das bactérias (>85%) eram bacilos gram-negativos. Quando um compartimento estava contaminado, o risco de contaminação do outro compartimento era elevado (>80%). A contaminação foi estatisticamente maior nos estojos com ranhuras (p=0,0149). Conclusão: A contaminação dos estojos parece ocorrer por bactérias que, em geral, não são encontradas em doenças oculares associadas ao uso de lentes de contato, sugerindo que existem outras variáveis decisivas nas infecções oculares de uma lente ou estojo contaminado. Contaminação de estojos de lentes de contato com fungos parece ser uma exceção. O uso de estojos com ranhuras é uma prática comum e apresenta um risco potencial à saúde ocular. Não foram encontradas diferenças significativas nos resultados dos testes bacterianos entre trabalhadores hospitalares e pessoas que não visitaram o hospital.

ABSTRACT Purpose: The aim of this study was to analyze the bacterial and fungal microbiota found in contact lens cases among two groups of patients to correlate the data on the habits of contact lens users and to evaluate whether there is a difference in the culture results between users of ridged and nonridged contact lens cases. Methods: Two groups (35 patients per group) were included, consisting of hospital workers and those who had not visited a hospital in the past 30 days, and a questionnaire regarding epidemiological data and habits related to contact lens and lens case use was administered. In addition, 140 samples collected from the right and left compartments of each lens case by swabbing the bottom of the wells were tested using bacterioscopy as well as fungal and bacterial cultures via computerized identification of the species. Results: No fungal growth was identified in any of the 70 contact lens cases; however, bacteria were found in 39 cases, and there was no statistical difference between the groups. Most bacteria (>85%) were gram-negative bacilli. Contamination inone compartment of the contact lens case elevated the risk of contamination of the other side (>80%). Moreover, contamination was statistically higher in the ridged cases than in nonridged cases (p=0.0149). Conclusion: The types of bacteria contaminating the cases are generally not seen in eye diseases associated with contact lens use, suggesting that other decisive variables are involved in eye infection from a contaminated lens or case. Fungal contamination of contact lens cases appears to be an exception. Ridged cases are commonly used by contact lens wearers and present a potential risk to eye health. In addition, the results of bacterial tests between hospital workers and those who did not visit a hospital were not significantly different.

ABSTRACT Objective To describe the safety and efficacy of pegvisomant therapy and the predictors of treatment response in acromegaly patients at a single tertiary reference center in Brazil. Materials and methods We retrospectively reviewed the clinical, hormonal and radiological data of acromegaly patients treated with pegvisomant in our center. We also evaluated the presence of the d3 isoform of the growth hormone receptor (d3GHR). Results Twenty-seven patients were included (17 women). Pegvisomant was used in combination with octreotide LAR in 20 patients (74%), in combination with cabergoline in one (4%) and as monotherapy in six (22%). IGF-I normalization was achieved in 23 patients (85%). Mild and transitory elevation of liver enzymes was observed in two patients (7.4%), tumor growth in one (3.4%) and lipodystrophy in two (7.4%). One patient stopped the drug due to headaches. The GHR isoforms were evaluated in 14 patients, and the presence of at least one d3GHR allele was observed in 43% of them, but it was not a predictor of treatment response. Only pre-treatment IGF-I level was a predictor of treatment response. Conclusion Pegvisomant treatment was highly effective and safe in our series of Brazilian patients. A better chance of disease control can be expected in those with lower pre-pegvisomant IGF-I levels.

ABSTRACT The Traveling Salesman Problem (TSP) is one of the most well-known and studied problems of Operations Research field, more specifically, in the Combinatorial Optimization field. As the TSP is a NP (Non-Deterministic Polynomial time)-hard problem, there are several heuristic methods which have been proposed for the past decades in the attempt to solve it the best possible way. The aim of this work is to introduce and to evaluate the performance of some approaches for achieving optimal solution considering some symmetrical and asymmetrical TSP instances, which were taken from the Traveling Salesman Problem Library (TSPLIB). The analyzed approaches were divided into three methods: (i) Lin-Kernighan-Helsgaun (LKH) algorithm; (ii) LKH with initial tour based on uniform distribution; and (iii) an hybrid proposal combining Particle Swarm Optimization (PSO) with quantum inspired behavior and LKH for local search procedure. The tested algorithms presented promising results in terms of computational cost and solution quality.

MÉTODOS: Estudo descritivo de corte transversal com amostragem não probabilística voluntária. Participaram do estudo 36 idosos (63,6±4,1 anos), sendo 12 praticantes de musculação, 12 praticantes de hidroginástica e 12 não praticantes de exercícios físicos. O nível de atividade física foi avaliado pelo Questionário Internacional de Atividade Física (IPAQ). A avaliação da força máxima foi realizada pelo teste de uma repetição máxima (1RM) em membros superiores e inferiores. A capacidade funcional foi avaliada pelos testes de levantar da cadeira em 30 segundos e velocidade de caminhada habitual e máxima. Foi utilizada Anova One Way com post-hoc de Bonferroni para comparação das variáveis dependentes entre os grupos com α=0,05. RESULTADOS: Todos os grupos foram classificados como ativos. O grupo praticante de musculação apresentou os maiores valores de força máxima, quando comparado ao praticante de hidroginástica e não praticante de exercícios físicos (p≤0,01). Além disso, os grupos praticante de hidroginástica e não praticante de exercícios físicos não apresentaram diferenças na força máxima (p=1,0). Já para o teste de levantar da cadeira, não foram observadas diferenças entre os grupos (p=0,07), o mesmo sendo observado no teste de velocidade de caminhada habitual (p=0,06) e máxima (p=0,22). CONCLUSÃO: A musculação mostrou-se mais eficaz para o aumento de força, mas o estilo de vida ativo é suficiente para a manutenção da capacidade funcional.

INTRODUCTION: Changes in strength and functional capacity due to aging can be improved through physical exercises practice such as strength training and hydrogymnastics. OBJECTIVE: To compare the strength and functional capacity among elderly individuals who practice strength training, hydrogymnastics and non-practitioners of physical exercises. METHODS: Descriptive cross-sectional study with voluntary non-probability sampling. The study included 36 elderly (63.6±4.1 years): 12 strength training practitioners, 12 hydrogymnastics practitioners and 12 non-practitioners of physical exercises. The level of physical activity was assessed by the International Physical Activity Questionnaire (IPAQ). The maximum force was performed by the one maximum repetition test (1RM) in upper and lower limbs. Functional capacity was evaluated by tests of rising from a chair in 30 seconds and usual maximum walking speed. One Way ANOVA test with post hoc Bonferroni was used to compare the dependent variables between the groups with α= 0.05. RESULTS: All groups were classified as active. The strength training group had the highest values of maximum strength when compared to hydrogymnastics group and non-practitioners of physical exercises (p≤0.01). In addition, hydrogymnastics practitioners and non-practitioners of physical exercises groups showed no differences in maximum strength (p=1.0). As for the chair lifting test, no differences were observed between groups (p=0.07) and the same was observed in habitual (p=0,06) and maximum (p=0,22) walking speed test. CONCLUSION: The strength training was more effective for increasing strength, but active lifestyle is sufficient to maintain functional capacity.

JUSTIFICATIVA E OBJETIVOS:O quadro doloroso do ombro limita o paciente de realizar suas tarefas diárias, assim como de realizar atividades dentro da sua jornada de trabalho. O objetivo deste estudo foi avaliar a relação entre a intensidade da dor, a incapacidade e os achados no exame de imagem de pacientes com dor no ombro.MÉTODOS:Foi realizado um estudo observacional analítico em 54 pacientes com possível lesão de ombro. Os participantes responderam um questionário de incapacidade, uma escala de intensidade de dor e em seguida foram submetidos ao exame de imagem. Foi realizada a análise de correlação entre a incapacidade, a intensidade de dor e o diagnóstico por imagem, além da comparação da intensidade da dor e do nível de incapacidade entre os participantes com e sem anormalidade no exame de imagem.RESULTADOS:A intensidade de dor média encontrada foi de 7,4±2,52. Houve alto grau de incapacidade (média de 57,2%). Nos exames de imagem analisados foram encontradas anormalidades em 59,3% dos laudos. Não houve correlação entre os achados na imagem e a intensidade de dor, assim como não houve correlação entre os achados na imagem e a incapacidade. Observou-se alta correlação entre intensidade de dor e o nível de incapacidade (Rho=0,67; p<0,001). A intensidade de dor e incapacidade não foram diferentes entre os participantes com ou sem algum tipo de anormalidade nos exames de imagem.CONCLUSÃO:Pacientes com queixas na região do ombro podem apresentar limitações nas atividades de vida diária e presença de dor, mesmo sem achados no exame de imagem.

A variação temporal e espacial dos hábitos alimentares e dos grupos tróficos de peixes demersais abundantes na baía de Santos e plataforma continental adjacente foi investigada. As amostras foram obtidas em setembro de 2005 e março de 2006, utilizando-se rede de arrasto de fundo. A análise dos conteúdos estomacais de 2.328 exemplares de 49 espécies demonstrou que a maioria se alimentou de uma grande variedade de presas, destacando-se os camarões, caranguejos/siris, anfípodes, misidáceos, poliquetas, ofiuróides, lulas e teleósteos. De acordo com as presas principais, os peixes foram agrupados em dez grupos tróficos. Os camarões foram presas importantes na baía e plataforma interna, e os ofiuróides apenas na plataforma média. Caranguejos/siris tiveram grande importância na dieta de várias espécies durante o verão, em especial na plataforma média. A variação espacial e temporal na alimentação dos peixes esteve associada ao padrão de distribuição e abundância de suas presas. A ingestão de camarões e caranguejos/siris está, provavelmente, associada à dinâmica das massas de água na região. Comparações intraespecíficas demonstraram que a maioria das espécies apresenta variação espacial e/ou temporal na dieta. A ictiofauna demersal pode ser categorizada em grupos tróficos mais abrangentes: piscívoros, comedores de invertebrados nectônicos, comedores de invertebrados bentônicos e comedores de invertebrados planctônicos.

The temporal and spatial variations of feeding habits and trophic groups of demersal fish species of Santos Bay and the adjacent continental shelf were investigated. The samples were taken in September 2005 and March 2006 by bottom otter trawling. The stomach content analysis of 2,328 specimens of 49 species showed most fish fed on a large range of food items but relied heavily on shrimp, crabs/swimming-crabs, amphipods, mysids, polychaetes, ophiuroids, squids, and teleosteans. The species were classified into ten trophic groups. Shrimp were an important food source in the Santos bay and inner shelf, while ophiuroids were important prey for predators of the middle shelf. Many species relied on crabs/swimming-crabs during the summer, especially on the middle shelf. The spatial and temporal variability in food resource utilization by fish were related to the pattern of distribution and abundance of their prey. The predation on shrimp and crabs/swimming-crabs seems to be related to the water mass dynamics of the region. Intraspecific comparisons demonstrated that most of the species display spatial and/or temporal variation in their diet. The demersal ichtyofauna can also be divided into the more general categories of piscivores, nektonic invertebrate feeders, benthic invertebrate feeders and planktonic invertebrate feeders.

A modelagem da produção de forragem com o uso de unidades fototérmicas (UF) foi utilizada com sucesso nos capins elefante cv. Napier, Tanzânia e Brachiaria em condições ótimas de adubação e disponibilidade hídrica. Havendo a necessidade de modelos de produção de forragens para diferentes níveis de adubação e de irrigação. Nesse sentido, o objetivo deste trabalho é propor modelos para o capim Tanzânia (Panicum maximum Jacq. cv Tanzânia) sob diferentes lâminas de irrigação (25, 50,75, 100 e 125% da ETc) e adubação nitrogenada em diferentes localidades do Brasil, a partir de unidades fototérmicas. Os modelos foram ajustados para as doses de 0, 30, 60, 110 e 270 kg de N ha-1, doses divididas em aplicações após cada corte, com um ciclo de 35 dias de descanso. Os modelos de produtividade ajustados apresentaram r² de 0,9999, de boa confiança para estimativa da produção de matéria seca do capim Tanzânia. Sendo assim, pode-se estimar a produção de matéria seca do capim Tanzânia para várias regiões do país, desde que se conheça a latitude local e as temperaturas máxima e mínima.

The mathematical model to predict the forage yield using photothermal units was utilized with success in Elephant grass, Thanzania and Brachiaria ruziziensis in the absence of water stress and nitrogen stress. The aim of this study was to propose models to estimate the forage yield of Thanzania grass under different irrigation (25, 50,75, 100 e 125% of ETc) and nitrogen level in various regions of Brazil. As such, models were developed to estimate the dry matter production of Panicum maximum Jacq. frass cv Thanzania in different irrigation and nitrogen levels, using photothermal units. The models were adjusted to doses of 0, 30, 60, 110 and 270 kg of N ha-1, doses were divided in applications after each evaluation, with a rest cycle of 35 days. The adjusted model presented good performance in predicting dry matter production of Thanzania grass, with r² = 0.9999. The results made it possible to verify that the proposed model can be used to predict forage production in different regions of Brazil. It can be estimated, with good precision. The production of Thanzania grass dry matter can be accurately estimated in specific places (in function of latitude and time of year), with the maximum and minimum temperature values.

Estudar modelagens através de dados geodésicos temporais com a possibilidade de predizer a posição de linha de costa é uma tarefa importante e pode auxiliar significativamente na gestão costeira. A área de estudo neste trabalho se refere ao município de Matinhos no estado do Paraná, Brasil. As linhas de costa temporais utilizadas para testar a modelagem preditiva são provenientes respectivamente da fotogrametria analógica para anos 1954, 1963, 1980, 1991 e 1997 e de levantamentos geodésicos utilizando GPS (Global Position System) para 2001, 2002, 2005 e 2008 (como controle). Dois testes com as redes neurais artificiais foram organizados mudando alguns parâmetros como: arquitetura, número de neurônios nas camadas ocultas e algoritmos de treinamentos. Quando comparados o valor dos resíduos entre a predição e a linha de costa de controle, os melhores resultados estatísticos indicam que o MAPE (mean absolute percentage error) são 0,28% utilizando a rede neural parcialmente recorrente de Elman com o algoritmo de treinamento quase-Newton e 0,46% para o caso da rede neural perceptron multicamadas com o algoritmo de treinamento utilizando o método Bayesiano com regularização.

The study of models using geodetic temporal data which can possibly predict the shoreline position is an important task and can significantly contribute to coastal management. The studied area is located at municipality of Matinhos in the Paraná State, Brazil. The temporal shoreline used to test the prediction model is respectively from analog photogrammetric data, related to the years 1954, 1963, 1980, 1991 and 1997, and GPS (Global Position System) geodetic surveys for 2001, 2002, 2005 and 2008 (as control). Two different tests with artificial neural network were organized setting the parameters like: architecture, number of neuron in hidden layers and the training algorithms. Comparing the residuals between the prediction to the shoreline of control, the best statistical results show the MAPE (Mean Absolute Percentage Error) is 0,28% using the Elman partially recurrent network with quasi-Newton training function and 0,46% using the neural network multilayer perceptron with Bayesian regulation training function.

As abordagens de inteligência computacional, tais como sistemas nebulosos e redes neurais artificiais, têm-se gradualmente estabelecido como ferramentas robustas para a tarefa de aproximação de sistemas não-lineares complexos e previsão de séries temporais. Em aplicações envolvendo a área de Finanças, evidências empíricas anteriores indicam que modelos de inteligência computacional são mais precisos, dada sua maior capacidade em capturar não-linearidades e outros fatos estilizados presentes em séries financeiras. Nesse sentido, este artigo investiga a hipótese de que os modelos matemáticos de redes neurais perceptron multicamadas, redes neurais função de base radial e o sistema nebuloso Takagi-Sugeno (TAKAGI; SUGENO, 1985) são capazes de fornecer uma previsão fora-da-amostra mais acurada que os modelos auto-regressivos de médias móveis (ARMA) e auto-regressivo de médias móveis supondo heterocedasticidade condicional auto-regressiva (ARMA-GARCH). O desempenho de previsão um-passo-à-frente dos modelos foi comparado utilizando-se séries de retorno da taxa de câmbio real/dólar (R$/US$) com freqüências de 15 minutos, 60 minutos, 120 minutos, diária e semanal. Resultados indicam que o desempenho dos modelos está diretamente relacionado à freqüência observada das séries. Além disso, os modelos de redes neurais obtiveram um desempenho superior em relação aos demais modelos considerados. A avaliação da estratégia de negociação estabelecida com base nas previsões geradas pelos modelos indicou que estratégias baseadas em modelos de redes neurais forneceram retornos superiores em relação àquelas baseadas em modelos ARMA e ARMA-GARCH e também em relação à estratégia buy-and-hold.

Computational intelligence approaches, such as artificial neural networks and fuzzy systems, have become popular tools in approximating complicated nonlinear systems and time series forecasting. In Finance applications, there is evidence that these computational intelligence models are able to provide a more accurate forecast given their capacity for capturing nonlinearities and other stylized facts of financial time series. Thus, this paper investigates the hypothesis that the mathematical models of multilayer perception, radial basis function neural networks (NN), and the Takagi-Sugeno (TS) fuzzy systems are able to provide a more accurate out-of-sample forecast than the traditional AutoRegressive Moving Average (ARMA) and ARMA Generalized AutoRegressive Conditional Heteroskedasticity (ARMA-GARCH) models. Using a series of Brazilian exchange rate (R$/US$) returns with 15 minutes, 60 minutes, 120 minutes, daily and weekly basis, the one-step-ahead forecast performance is compared. The results indicate that forecast performance is strongly related to the series' frequency, possibly due to nonlinearities effects. Besides, the forecasting evaluation shows that NN models perform better than the ARMA and ARMA-GARCH ones. In the trade strategy based on forecasts, NN models achieved higher returns when compared to a buy-and-hold strategy and to the other models considered in this study.

Abstract: En | Text: En | PDF: En

Most of the works accomplished in the optimization area in the cement industry are addressed to solve problems just considering only one variable, forgetting that it includes too many variables and they act at the same time. Among the main variables it can be mentioned the quality of the final product, the environmental ones, the costs along the process and the reduction of the fossil fuels (primary) employed through the use of alternative fuels (secondary), among others. The present work intends to build a mathematical model using optimization tools seeking to improve the cement production process foreseeing what can happen with the clinker and the emissions when the industrial residues co-processing technology is used as alternative or secondary fuel. In the optimization process a new approach called Particle Swarm Optimization (PSO) is employed, which is based on the Cauchy and Gauss distribution considering several process restrictions such as the specific fuel consumption, the cement quality and the environmental impact. The results obtained with PSO were precise and promising and they were compared with the classical Sequential Quadratic Programming (SQP). It was also possible to evaluate the levels of primary fuels substitution through the alternative or secondary ones.
