This paper proposes an extended data envelopment analysis (DEA) model for deriving eco-efficiency. In order to derive eco-efficiency, the proposed model utilizes the concepts of operational efficiency and environmental efficiency. Since DEA can separately measure operational efficiency and environmental efficiency, the treatment for constructing the unified indicator is required to ultimately e...

Background: Recess provides a daily opportunity for children to engage in moderate-to-vigorous (MVPA) and vigorous physical activity (VPA). Limited research has investigated the effects of recess-based interventions on physical activity using large sample sizes whilst investigating variables that may influence the intervention effect. The aim of the study was to investigate the short-term effec...

In general, estimates of uncertainties in measured values give an idea of the quality of the measurement. However with environmental noise measurements this is not necessarily the case since the variables affecting the measured levels can often not be controlled. Consequently an appreciation of the uncertainties in results lead rather to a better understanding of the measurement and its potenti...

Abstract Plant-derived reusable resources such as biomass feedstock for fuel use and upcycling food products have attracted attention solving environmental problems. In general, that are inappropriately consumed include various energy production pathways through the fermentation or gasification process, which would be attractive anaerobic digestion of wasted foods to make livestock feed. terms ...

Recall the first time you used Google EarthTM. Most people would typically key in their address and find where they lived on a digital representation of reality application. It was not uncom...

Transportation system has a close bearing on the prosperity of society. However, transportation infrastructures are highly vulnerable to extreme events. Therefore, identifying most critical component is among first priorities network planners and managers. This paper proposes novel framework identify for road system. A key characteristic vulnerability assessment travelers’ response changes in t...
