In this article, a performance assessment of the evacuation system is established for educational buildings. Structural and geotechnical information of the building is collected and introduced into a database. A similar procedure was realized for the information related to the occupants. Using this information, a) the structural fragility and localized collapse were determined and b) the interaction of the person with the partial collapse was established. For the first aspect, nonlinear time history was used, and for the second, the agent-based modeling was applied to recreate the reaction of people that face the micro collapse. Therefore, the important results of this evaluation are: 1) To localize collapsed beans and columns that make inoperable evacuation routes, 2) to localize bottleneck areas that people concentration during evacuation, and 3) quantification of affected people, in t...

Nowadays in the pandemic of Covid-19, it is important to know the ravages of the state of emergency in schoolchildren. For this reason, this cross-sectional analytical study aims to determine the association between screen time and the level of physical activity (PA). A total of 169 primary school students from Metropolitan Lima participated. They were evaluated through the screen time questionnaire, the Physical Activity Questionnaire for Children (PAQ-C) and a sociodemographic report. The results indicate that 52.1% gained weight during the pandemic and 62.7% of students used screens for more than 5 hours on a typical day from Monday to Friday. The PAQ-C determined that 74.6% did not comply with the recommended physical activity times (AF-NR= < 2.73). In this study, no statistical association was found between children's screen time and meeting recommended physical activity levels. How...
