Resumen en portugués Processaram-se registros da pressão arterial sistólica (PAS), diastólica (PAD) e da freqüência cardíaca (FC) efetuados durante todo o dia em situação basal e as 6, 26 e 52 semanas de tratamento. Para isto se aplicaram técnicas multidimensionais de dados com o enfoque da escola francesa (análise de correspondências múltiples seguido da construção de clusters sobre coordenadas fatoriais), logrando uma partição em três classes. Consideraram-se em seguida cad (mas) a classe como um objeto simbólico e se realizaram gráficos de estrelas multivariantes que puseram em evidência os diferentes perfis das classes, possibilitando uma satisfatória visualização gráfica.

Resumen en inglés Systolic and diastolic arterial blood pressure and heart frequency performed all along the day under basal conditions and at 6, 26 and 52 weeks of treatment were processed. Multidimensional data techniques were applied with the French school approach (multiple correspondence analysis followed by construction of clusters on factorial coordinates), achieving partition in three classes. Thereafter, each class was considered as a symbolic object and multivariant star graphs were drawn to show the different class profiles, making possible a satisfactory graphic visualization.

Cumplimiento de los Protocolos de Prevención de la Legionelosis en Edificios Públicos/ Legionnaires' disease prevention protocol performance in public buildings

Resumen en español Objetivo Investigar la relación entre el cumplimiento del Real Decreto 865/2003 y el Decreto 287/2002, por los que se establecen los criterios higiénico-sanitarios para la prevención y control de la legionelosis, y el riesgo debido a un deficiente mantenimiento higiénico- preventivo de las instalaciones de agua. Métodos Estudio descriptivo realizado en la provincia de Málaga (España) sobre una muestra correspondiente a 214 edificios públicos, 83 variables e interp (mas) retación sobre el porcentaje de cumplimiento de la normativa. Medida del riesgo, definición de clusters (tipificación del riesgo), estimadores clásicos y robustos, estimación jackknife e intervalos de confianza bootstrap . Resultados Riesgo por incumplimiento parcial entre el 11,1 (riego, Centros Privados de ESO) y 85,7 % (AFS, Institutos de Educación Secundaria). La normativa se cumple en 82 edificios, 130 la incumplen y 2 no presentan instalaciones de riesgo. Cumplimiento total 38 %. Estimación para el cumplimiento parámetros de localización 0,33-0,36 (33-36 %) y de escala 0,11-0,16. Estimador jackknife del sesgo reducido 0,35071 (estimación media). Intervalos de confianza bootstrap con extremos [0.26, 0.47]. Conclusión El menor riesgo por incumplimiento parcial corresponde a Institutos de Educación Secundaria y el mayor por distribución a los hoteles de cuatro y tres estrellas. Selección del parámetro de localización estimador de Huber y de escala NMAD . Atendiendo al parámetro «razón poblacional» y estimador «razón muestral», el estimador jackknife del sesgo reducido es insesgado. Intervalos de confianza basados en las técnicas bootstrap , partiendo de la media 0,2- recortada muestral y coeficiente de confianza 0,95, muy aproximados. Resumen en inglés Objective Studying the relationship between fulfilment of royal decree 865/2003 and decree 287/2002 (establishing hygienic-sanitary criteria for preventing and controlling Legionnaires' disease) and risk arising from deficient preventative-hygienic water facility maintenance. Methods This was a descriptive study carried out in the province of Málaga (Spain) on a sample of 214 public buildings using 83 variables and interpreting legislation fulfilment percentages. Risks w (mas) ere measured, clusters defined (related to risk typification) and classic and robust estimators, jack-knife estimation and bootstrap confidence intervals were calculated. Results 11.1 % (irrigation, ESO private centres) and 85.7 % (AFS, secondary education institutions) partial non-fulfilment/breach risks were found. Eighty-two buildings complied with current standards, 130 failed to fulfil them and 2 did not display risk facilities. There was 38 % overall compliance with established norms. Location parameter fulfilment was estimated as being 0.33-0.36 (3336 %) and scale as 0.110.16. Reduced bias jack-knife estimator was 0.35071 (average estimation). Bootstrap confidence interval extremes were 0.26 and 0.47. Conclusion Secondary education institutions represented the least risk due to partial noncompliance and four- and three-star hotels the greatest. Huber estimator was selected as location parameter and NMAD as scale parameter. Regarding the population ratio parameter and sample ratio estimator, it was considered that the jack-knife estimator of reduced bias was unbiased. Confidence intervals based on bootstrap techniques (starting from 0.2trimmed mean sample and a 0.95 confidence coefficient) were very approximate.
