This research effort examines the creation of mission impact analysis visualizations to enhance situational awareness. It focuses on using prefuse to create a visualization that allows the user to quickly understand the impact of the failure of any element needed directly or indirectly for a mission. The visualization correctly identifies the direct or indirect impact on physical requirements such as network links and servers as well as non-physical elements such as the generation of a report, or ability to perform a task. The visualization provides an overview of the situation, as well as including enhancements to allow for greater detail on any element to be viewed. The result of this research is the foundation for a tool to allow commanders and others, at a glance, to understand the scope of mission impact when an outage occurs.

PurposeTo identify whether physical fitness (PF) components play a moderating role in the relationship between TV time and adiposity levels.DesignCross-sectional study.SettingFew studies have examined if different PF levels modify the association between TV time and adiposity in adolescents. Studies often focus on the isolated relationships between obesity and TV time, or obesity and PF levels.Subjects1071 adolescents (617 girls), aged 12 to 17 years.MeasuresCardiorespiratory fitness (CRF), abdominal muscular endurance, and lower limb strength were evaluated using the protocols of the Projeto Esporte Brasil fitness testing battery. TV time was obtained using a self-reported questionnaire. Body mass index (BMI) and waist circumference (WC) were also assessed. Moderation analyses were conducted through multiple linear regression models with the following associations tested in different models: PF components, TV time, and interaction (PF component x TV time) with adiposity parameters (BMI and WC);ResultsA significant interaction term was found for CRF and TV time in the association with both WC (β: −.005; 95% CI: −.009; −.001; P = .012) and BMI (β: −.002; 95% CI: −.004; −.001; P = .009).ConclusionCRF moderates the relationship between TV time and adiposity measures in this cross-sectional analysis. These data support strategies looking at increasing physical activity levels to improve CRF and avoid the development of excess abdominal obesity and excess weight.
