194 The aim of this study was to determine the psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT and AUDIT-C) in order to detect problems related to the consumption of alcohol in the university population. The sample consisted of 1309 students. A Weekly Alcohol Consumption Diary was used as a gold standard; Cronbach’s Alpha, the Kappa index, Spearman’s correlation ...

background helicobacter pylori infection is a common infection that affects human beings. this infection also affects children. different diagnostic methods such as serology, stool antigen detection, rapid urease test and histology are used to detect this microorganism. objectives the aim of this study was to determine the correlation between serology and histology/rapid urease test. patients a...

OBJECTIVE To evaluate the adequacy and accuracy of cut-off values currently recommended by the WHO for assessment of cardiovascular risk in southern Brazil. DESIGN Population-based study aimed at determining the predictive ability of waist circumference for cardiovascular risk based on the use of previous medical diagnosis for hypertension, diabetes mellitus and/or dyslipidaemia. Descriptive ...

Traditional map-labeling algorithms ensure that the labels being placed do not overlap each other, either by omitting labels or scaling them. This is undesirable in applications where the points to be labeled are moving. We develop and experimentally evaluate a heuristic for labeling moving points. Our algorithm labels all the points with labels of a fixed size, while trying to minimize the num...

The increase in life expectancy can influence the prevalence of dementias in the population. Instruments that evaluate cognitive functions such as the Mini Mental State Examination (MMSE) are necessary for the investigation of dementia. The supposition that patient score on the MMSE can be influenced by academic level points to the need for establishing cut-off values that take into account edu...

The aim of this study was to establish which cut-off point for the forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio (i.e. fixed 0.70 or lower limit of normal (LLN) cut-off point) best predicts accelerated lung function decline and exacerbations in middle-aged smokers. We performed secondary analyses on the Lung Health Study dataset. 4045 smokers aged 35-60 years with mil...

The goal of this research is to extract and delineate building ground plans from LIDAR data. Our approach consists of three steps: first of all, the raw point cloud has to be classified into terrain points and off-terrain points. Secondly, the off-terrain points (the potential buildings) have to be aggregated to form connected building blobs. Those blobs that exceed a certain size and have cert...
