Introduction: A childs world centers around the home, school and the local community. These should be healthy places. But in reality, these places are often so unhealthy that they underlie majority of accident and disease among children in the developing world. The aim of this study was to determine ergonomic, safety and environmental health status at primary schools in Markazi province. Materi...

Background: Providing health facilities and attention to the physical and mental health of students are very important and it can affect the amount of their learning. The purpose of this study was the investigation of the environmental health status and safety of public and non-public elementary schools of Mashhad-Iran. Method: In this descriptive cross-sectional study, 100 public and non...

Traditional safety and health system measurement procedures, practiced in various industries produce qualitative results with a degree of uncertainty. This paper presents a fuzzy-logic-based approach to developing a fuzzy model for assessing the safety and health status in the tea industry. For this, the overall safety and health status at a tea estate has been considered as a function of 4 inp...

We study the possible singularities of isotropic cosmological models that have a varying speed of light as well as a varying gravitational constant. The field equations typically reduce to two dimensional systems which are then analyzed both by dynamical systems techniques in phase space and by applying the method of asymptotic splittings. In the general case we find initially expanding closed ...

Después de años de un continuado crecimiento muy por encima el de nuestro producto interior bruto, el gasto sanitario empieza mostrar inequívocamente su frenada. Las alegrías de su pasado umento se tornan en tristeza y decaimiento, con una verosímil endencia a ir a menos. Es comprensible que la situación no suscite legría, pero no deja de extrañar la generalizada preocupación por l «mal color» ...

We develop an analytically tractable consumption-savings model for a liquidityconstrained agent who faces both permanent and transitory income shocks. We find that risk aversion and intertemporal substitution have very different effects on both consumption and the steady-state savings target. Moderate changes in risk aversion have large effects on consumption and buffer-stock savings. With perm...
