INTRODUCTION Childhood asthma is the main public health problem in world, and dramatically has increased in developed as well as developing countries. AIM To assess prevalence and risk factors for asthma based on ISAAC questionnaire. MATERIAL AND METHODS It was a cross-sectional school population-based study which was carried out on 1803 school children aged 6-7 and 13-14 in Ahvaz city, Khu...

OBJECTIVE Few studies have examined variability among physicians in the perception and interpretation of asthma symptoms. We report the results of a pilot study to investigate the variability of symptom description and diagnostic labeling and nomenclature among a group of clinicians using standardized audiovisual presentations of asthma.

To validate the prevalence rate of symptoms of asthma produced by the phase I ISAAC (International Study of Asthma and Allergies in Childhood) study, hypertonic saline challenge test was carried out during the phase II study at a year after the phase I study. For the phase II study, six middle schools from three cities in the phase I study were selected. Finally, 499 children who responded to b...

Teamwork is becoming increasingly important in a large number of multiagent applications. With the growing importance of teamwork, there is now an increasing need for tools for analysis and evaluation of such teams. We are developing automated techniques for analyzing agent teams. In this paper we present ISAAC, an automated assistant that uses these techniques to perform post-hoc analysis of R...

This paper presents a description of ISAAC, the Immersive Simulation Animation And Construction program designed and built at the University of North Carolina at Chapel Hill (UNC-CH). ISAAC is a scene composition application for the interactive construction of virtual worlds. Working directly in a virtual environment, objects can be positioned, oriented and scaled using direct and indirect mani...

PURPOSE The study aims to classify schools based on traffic pollutants and their complex sources, to assess the environment, to determine the state of allergic diseases among students using the International Study of Asthma and Allergies in children (ISAAC) questionnaire, and to assess their connection to air pollutants.
