Occupational stress is considered to be a main health problem for both individuals and organizations. This study has investigated the measurement of occupational stress among Management Information Systems (MIS) Users in different banks in the Kingdom of Bahrain. Furthermore, to identify their high job stressor factors and increase understanding of the impact of individuals differences in occup...

The poultry abattoir industry continues to grow and contribute significantly to the gross domestic product in many countries. The industry expects working shifts of eight to eleven hours, during which workers are exposed to occupational hazards which include physical hazards ranging from noise, vibration, exposure to cold and ergonomic stress from manual, repetitive tasks that require force. A ...

in this study, the authors reported a case of woman with severe compulsion who became pregnant during the repetitive transcranial magnetic stimulation. we carried out repetitive transcranial magnetic stimulation and behavior therapy simultaneously after repeated medications' refraction. the patient received 20 sessions 1 hz repetitive transcranial magnetic stimulation in right dorsolateral...

This paper presents a new design method for repetitive-control systems based on two-dimensional (2D) system theory and optimal control. First, a 2D model is established that describes the control action within a repetition period and the learning process between periods. Next, the problem of designing a repetitive controller is formulated as an optimization problem for the 2D model. Then, one-d...

background : although many studies have been performed on occupational and industrial musculoskeletal disorders in iran, small scale industries have been less studied and evaluated. the purpose of this study was to perform an ergonomic assessment of handicraft workers in isfahan, iran, using the assessment of repetitive tasks (art) tool in 2015. methods: this descriptive-analytical and cross-se...

No studies were located that examined health effects in humans or animals exposed to threeor fourmembered mixtures of the five components of concern. No PBPK models were found for threeor fourmembered mixtures of these chemicals. The following subsections present evaluations of health effects data and discussions of mechanistic information pertinent to the joint toxic action of each pair of com...

Background: Obsessive-compulsive disorder (OCD) is a psychiatric in which people experience repetitive, unwanted thoughts, called Obsessions and repetitive actions they cannot get rid of it, Compulsions. Aim: to the prevalence OCD among psychology students at university Garmian compare grades, age groups gender students. Method: cross-sectional study design, purposive sampling method, using Yal...

This paper develops repetitive and iterative learning control design and analysis for back stepping controlled nonlinear systems. To precisely track periodic or finite duration trajectories for nonlinear systems, back stepping control is first designed to render closed loop stability and, in theory, asymptotic tracking performance. However, due to the sensitivity to the unmodelled dynamics plan...
