Objective: Action video games are increasingly recognized for their potential to enhance cognitive capacities, including working memory (WM). However, most studies require extensive training or prior gaming experience. We examined whether a single, short-term session of Snail Mail, an arcade-action game, could boost WM precision compared passive control condition. Method: Thirty six healthy adults (18 34 years) were randomly assigned either play Mail (Intervention) watch episodes Shaun the...

Limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely develop swallowing dysfunction based on neuroimaging. The aim this study was investigate relationship between lesions in a sample acute conscious stroke patients.In cross-sectional study, 113 patients (69 male mean [standard deviation (SD)] age 64.37 [15.1]), participated study. Two neurologists one radiologist localized...

The present study was designed to investigate the simultaneous effects of physical, psychosocial and other work-related risk factors on work ability index (WAI) score among industrial workers.This used a cross-sectional design with questionnaire survey. A total 280 workers were included in study. Data collected using three questionnaires including Persian version WAI, job content an author-developed measure (to assess factors, health-related socio-demographic characteristics).The majority...

Cognitive status is important for performing the assessment and treatment of dysphagia. Nonetheless, cognitive neuropsychological profile patients with stroke dysphagia not studied as deeply enough it should be. On one hand, focal non-focal brain lesions may lead to disorders, on other possibly affects swallowing. In this study, cognition supposed be a mediator between lesion swallowing disorder (dysphagia). The role attention mediators was evaluated via three causal models in which...

Control charts are widely used for monitoring the quality of a product or process. Their implementation cost motivates researchers to design them with lowest and most desirable statistical properties. Usually, function is optimized subject However, also depends on properties, minimizing it as only objective not an efficient method economic control charts. In this paper, function, well including probability Type I error, power X¯ chart, Average Time Signal (ATS), considered objectives;...

In this study, we propose a control chart for monitoring two-stage processes whose quality characteristic to be monitored in the second stage follows binomial distribution. The proposed is based on deviance residual which essentially generalized log-likelihood ratio statistic obtained from linear model. To establish relationship between first- and second-stage characteristics, using new link function model framework. performance of with compared that under traditional logit terms average run...

This study aimed to investigate construct validity and factor structure of the Persian Occupational Self-Assessment (OSA; ) based on model human occupation (MOHO). Three hundred thirty-six (179 male 157 female) Iranian junior high students were measured using OSA. The data analyzed a Confirmatory Factor Analysis (CFA) Rasch Rating Scale Model (RSM). In combination, CFA RSM results provided strong evidence for version. indicated that hypothesized second-order could explain relationship OSA...

Background: The high item numbers is one of the Work Ability Index (WAI) limitations that make it difficult to be completed by workers. Using single-item Score (WAS) as a simple proposed solutions which valid and suitable measure for work ability. Objectives: present study aimed assess ability using WAI WAS instruments compare their results among Iranian Methods: This cross-sectional was done on 1579 workers from eleven different sectors located in geographical areas Iran. measured full...

This study aimed to investigate the construct validity and factor structure of NEO-Five Factor Inventory (Costa & McCrae, 1992) in Iranian population. Participants were 1639 (780 male, 859 female) Tehran people aged 15-71. The results explanatory analysis showed no notable differences between structures extracted by oblique orthogonal rotations didn’t replicate scoring key. Openness Agreeableness had more psychometric problems (low internal consistency high deleted items). female’s...

Control charts are the most important tools of statistical process control used to discriminate between assignable and common causes variation improve quality a process. To design chart, three parameters including sample size, sampling interval, limits should be determined. The objectives hourly expected cost, in-control average run length, power time signal. Different approaches such as design, economic economic-statistical have been considered by many researchers. Recently, multi-objective...
