Background: This st udy aims t o evaluat e t he associat ion bet ween envi ronment al and socio-economic condit ions wit h asthma prevalence in t he eight ISAAC cent res in North-East Brazil. Met hods: Est imates on occurrence, severit y and medical diagnoses of asthma in the previous 12 months were compared using environmental and socioeconomic indicators. Associat ions were assessed using sim...
In a multicentre European hospital study we measured influenza vaccine effectiveness (IVE) against A(H3N2) in 2016/17. Adjusted IVE was 17% (95% confidence interval (CI): 1 to 31) overall; 25% (95% CI: 2 to 43) among 65-79-year-olds and 13% (95% CI: -15 to 30) among those ≥ 80 years. As the A(H3N2) vaccine component has not changed for 2017/18, physicians and public health experts should be awa...
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 ...
We focus on some prelimi~lcny, theoretical and practical, requirements for an agent-based Jystem for cognitive interaction with older people. CVe stress (a) the acceptability of an artiJicia1 agent by elders; (h) a user model, which includes user knowledge, e-epectations, goals; (c) a representation system, (0 an interaction Jysfem, including physical and verbal interaction. We describe in some...
در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدمقطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی شده نتایج نشان می‌دهد افزایش نرخ عدمقطعیت، مییابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز میی...
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...
