Resumo -Atualmente as alterações ocorridas na precipitação pluviométrica e em suas características tem sido um fator preocupante para a população. Este trabalho teve por objetivo avaliar a variabilidade espacial da precipitação pluviométrica no Estado da Bahia com base nos valores das coordenadas geográficas das estações de medição. Foram utilizados os valores de precipitação pluvial levantados para 71 postos pluviométricos localizados na área do estado, avaliando-se a média mensal das séries históricas usadas. Os dados foram submetidos primeiramente à análise estatística clássica e depois foi realizada a modelagem da variabilidade espacial. Posteriormente se aplicou a análise geoestatística, sendo os dados submetidos a procedimentos de interpolação que estima valores sem tendência e com desvios mínimos em relação aos valores conhecidos. A utilização da geoestatística permitiu definir e, neste caso, quantificar a dependência espacial existente para os dados de precipitação pluviométrica no Estado da Bahia.Palavras-chave: variabilidade espacial; coordenadas geográficas; estações de medição. Annual rainfall mean spatial distribution at Bahia State, BrazilAbstract -Currently the changes in rainfall and their characteristics has been a worrying factor for the population. This study aimed to evaluate the spatial variability of rainfall in the State of Bahia, Brazil based in the values of the geographic coordinates of the measuring stations. We used rainfall values from 71 rain gauge stations located within the state area, evaluating the monthly average from the available time series. The data were first submitted to the classical statistical analysis and then the spatial variability modelled. Later, geostatistical analysis were applied, and the data submitted to interpolation procedures which estimates values without trend and with minimal deviations in relation to known values. The use of geostatistics enabled to define and quantify the existing spatial data dependence for rainfall in the state of Bahia.Key words: spatial variability; geographic coordinates; measurement stations. IntroduçãoAtualmente as alterações ocorridas na precipitação pluviométrica e em suas características tem sido um fator preocupante para a sociedade. A chuva é um dos elementos climáticos mais diretamente relacionados à produção agrícola, devido ao seu caráter aleatório, aumentando, em consequência, os riscos na programação das atividades do setor agrícola (MELO JUNIOR et al., 2006). Sendo que sua distribuição é de maneira irregular tanto em escala temporal, como espacial. A obtenção da correta distribuição espacial para precipitação é relevante no planejamento agrícola, no que diz respeito à instalação de culturas e sua influência na agricultura (SANTOS, 2010). A quantificação das chuvas com intensidades superiores ao suporte do ambiente é importante no planejamento agrícola e ambiental para o correto dimensionamento das obras, tanto na construção civil quanto na conservação do solo (VIEIRA; CARVALHO, 2001). O estudo da variabilidade tempor...

The presence of damage associated with cerebral palsy (CP) often requires the long-term continuous use of prescription drugs. Among the adverse side effects of these drugs are decreased salivary flow and increased risk for caries. Objective: To determine whether those responsible for CP patients received orientation regarding the necessity of oral hygiene after the administration of drugs of continuous oral use and the caries experience in patients with CP. Method: Participating in this study were 205 children with medical diagnosis of CP, of both genders, aged 0-12 years (6.6 ± 2.9) attending a preventive program in dentistry in a reference institution of rehabilitation in São Paulo-SP. The data regarding gender, movement disorder and clinical types of CP were collected from medical records. In an interview format, the caregivers reported whether there was use of any continuous medicine. They were asked what form it took, whether the caregivers had received prior guidance on the importance of oral hygiene after the use of medicines, who performed the oral child's hygiene, and how often it was done. Their caries experience was recorded based on whether a given tooth was decayed (D, d) missing (M, m) or filled (F, f) (DMFT). The sample was divided into two groups according to whether they used continuous drugs (group 1: G1) or did not (group 2: G2). The Chi-square test and Student's t test were used, with the level of significance set up at 5%. Results: G1 (n = 110) and G2 (n = 95) were similar in terms of gender (p = 0.343) and age (p = 0.514). However, they differed significantly in relation to the clinical pattern, with G1 presenting significantly higher percentages of patients with tetraparesis (p < 0.001). Considering only the G1, it was observed that the subgroup that used medicine in oral solution form (solution, n = 65) differed significantly from that using tablets (tablets, n = 45) in relation to their previous orientation for hygiene oral (p = 0.013), in that the solution subgroup had been better oriented. With regard to oral hygiene, the solution subgroup had significantly higher percentages (p = 0.044) of children requiring supervision and completion of the oral hygiene when compared to the tablet group. The comparison of caries experience between G1 and G2 showed that the G1 had significantly higher values for their DMF index (p = 0.048), and fewer caries-free patients (p = 0.016) when compared to G2. Conclusion: Although those responsible for the patients receiving medication in the form of oral solution were better oriented, these patients presented higher values of caries experience.
