INTRODUCTION Smoking is a public health risk; the prevalence of smoking among adults in Nebraska is 18.4%. Studies indicate that maltreatment of children alters their brain development, possibly increasing risk for tobacco use. Previous studies have documented associations between childhood maltreatment and adult health behaviors, demonstrating the influence of adverse experiences on tobacco us...

BACKGROUND The validity of exposure data collected from proxy respondents of myocardial infarction patients has scarcely been studied. We assessed the level of disagreement between myocardial infarction patients and their spouses with respect to the reporting of the patient´s cardiovascular risk exposures. METHODS Within the frame of the Stockholm Heart Epidemiology Program (SHEEP), a case-co...

Assign the students the appropriate task associated with this own capabilities and knowledge, and form rights groups among team members are two main problems that a Pedagogical Agent –acting like a trainermust solve into a Collaborative Virtual Environment for training. We use reusable learning objects design by contract to formulate a Student Knowledge Model and a student ZPD, concepts derived...

This paper describes the physical exposures required to perform a sawmill job associated with a high incidence of upper extremity musculoskeletal injury. Exposure variables are described by multiple posture, exertion and frequency definitions and the comparability of those definitions are examined. Effective industrial prevention efforts require an accurate assessment of risk. Surface electromy...

exposure to O3 showed similar but nonsignificant associations. No associations were observed for PM2.5, PM10, or NO2, although adjustment for these pollutants strengthened the childhood O3 associations. Conclusions—Childhood exposure to O3 may be a novel risk factor for CIMT in a healthy population of college students. Regulation of air pollutants and efforts that focus on limiting childhood ex...

The paper shows how established two-dimensional multi-media technologies were used to develop robust prototypes which were then observed in use by children. Results from these phases have been used to guide the current phase of work. This involves the construction of a three-dimensional shared VE using the experimental Deva Virtual Reality system.

odine-131 (131I) has been known as a radionuclide with potential adverse health effects following both occupational and environmental exposures (NCRP 1985, Zanzonico and Becker 2000, Astakhova et al. 1998). 131I has a physical half life of 8 days, biological half life of 80 days, conceptually an effective half life of 7.3 days. With respect to occupational exposures to 131I, there are two categ...
