BACKGROUND Most evidence of the effectiveness of influenza vaccines comes from studies conducted in primary care, but less is known about their effectiveness in preventing serious complications. Here, we examined the influenza vaccine effectiveness (IVE) against hospitalization with PCR-confirmed influenza in the predominant A(H3N2) 2011-2012 influenza season. METHODS A hospital-based, test-n...
Background: Most of cesarean deliveries are performed with regional anesthesia especially spinal anesthesia (SA). Disadvantages of SA include maternal hypotension and fetal asphyxia. This study was conducted to find prophylactic strategies for prevention of maternal hypotension in the women who were candidate for cesarean in Rasht Azzahra Hospital in 2001. Materials and Methods: This study was ...
By combining physical activity and exposure to nature, green exercise can provide additional health benefits compared to physical activity alone. Immersive Virtual Environments (IVE) have emerged as a potentially valuable supplement to environmental and behavioral research, and might also provide new approaches to green exercise promotion. However, it is unknown to what extent green exercise in...
We have developed a syntactic approach to representing knowledge within the situation calculus using interval arithmetic. Knowledge was first incorporated into the situation calculus using a possible-worlds approach. Unfortunately, this previous approach is not amenable to easy implementation. This is because it is not clear how to specify the initial situation as the number of possible worlds ...
In the present study, side preferences in spontaneous visual exploration were assessed systematically in 27 patients with idiopathic Parkinson's disease (IPD) and 17 age-matched controls. Assessment of initial visual exploration asymmetry (IVE) was based on the exploration of texture arrays requiring attentive oculomotor scanning. As shown in a previous study, most healthy subjects exhibit a ma...
This paper presents comparat ive fun experiments in the innovat ive playground ‘Playware’ which is a combinat ion of physical and virtual components for act ivat ing physical and social children’s play. For this purpose, a quant itat ive approach to entertainment modeling based on psychological studies in the field of computer games is int roduced. The paper invest igates quant itat ively how t...
In this study, we present a composite spatial manipulation framework for the redirected walking technique. The proposed focuses on utilizing two different approaches simultaneously to manipulate user’s position and orientation in physical space, aiming substantially improve their redirection confined space reduce special requirements RDW Each approach utilizes perceptual processes. first is dis...
This study expands the literature on high impact practices by assessing effect of global experiences, including international virtual exchange (IVE) and abroad, student success, measured as GPA, first-year retention, graduation rate. Our dataset tracks over 47,000 students 10 years at a large U.S. university. fixed effects models show that IVE studying abroad increase average GPA. Using logit m...
