Background: Cognitive decline in normal aging is a major concern in aging societies as it impacts independence in daily life, quality of life and life expectancy. Population aging in the coming decades makes the prevention of cognitive decline and maintenance of functional capacity, important public health issues due to the social impact and economic costs of the demographic process. Objective: Research aims to evaluate the effectiveness of combined digital inclusion and physical activity interventions in the prevention of cognitive and functional loss among elderly residents in a large urban center in Brazil. The study is a comparative controlled study in primary care setting. Methods: We sampled 112 individuals from a population cohort of adults ages 60 and older, previously evaluated by Clinical Dementia Rating scale (zero and 0.5 scores), without depressive symptoms allocated to intervention group (IG) and control group (CG). IG participants attended a computer-based digital inclusion program combined with physical activity, with 80-min sessions twice a week for 17 weeks, whereas the CG followed their daily routine. We administered neuropsychological tests to all participants at baseline and follow-up (Montreal Cognitive Assessment - MoCA, Mini-Mental Status Exam - MMSE, list of words, verbal fluency, and animal categories), plus an evaluation of independence in activities of daily living – ADL and the Geriatric Depression Scale - GDS. Results: An intention-to-treat analysis showed an average increase of 1.23 points in MoCA scores after the intervention (p=0.012). Secondary analysis considering the number of sessions attended showed that MoCA scores increased 0.074 points on average for each session attended (p<0.001) and MMSE scores increased 0.029 points on average for each session attended (p<0.022). There were no statistical differences post-intervention for the other variables. Conclusions: The intervention improved global cognition among elderly residents.

The increasingly robust High Performance Computing (HPC) systems have promoted many researches on fault tolerance mechanisms. However, the efficiency of these techniques is an important challenge, as the data and resources demand is also getting higher. in this work, we presents how the framework Apache Hadoop implements the Checkpoint and Recovery technique for fault tolerance providing on its distributed file system (Hadoop Distributed File System). The demand of large amounts of data from all applications supported by Hadoop framework can compromise the mechanism efficiency, once its configurations attributes are defined statically. So we present a dynamic configuration mechanism to checkpoint for Apache Hadoop through a resource monitoring, whose goal is to make the Hadoop checkpoint adaptable. The proposed mechanism is then evaluated and submitted to performance tests.
