welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. many components of welding fumes can potentially affect the lung function. this study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in iran. this historical cohort study asses...
The Scanning Probe Microscopes (SPMs) based lithographic techniques have been demonstrated as an extremely capable patterning tool. Manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. In this paper, a qualified overview of diverse lithog...
Members of the 67th World Health Assembly in 2014 were presented with a framework document to guide World Health Organization (WHO) engagement with non-state actors, a key part of WHO reform kick-started in 2011. According to this document, non-state actors include four distinct constituencies: i) nongovernmental organizations (NGOs), ii) private sector entities; iii) philanthropic foundations;...
Multisectoral actions for health, defined as actions undertaken by non-health sectors to protect the health of the population, are essential in the context of inter-linkages between three dimensions of sustainable development: economic, social, and environmental. These multisectoral actions can address the social and economic factors that influence the health of a population at the local, natio...
Introduction. The effect of exercise program on the prevention of upper extremities musculoskeletal disorders has attracted the attention of researchers. On the other hand, in assembly workers, the risk of these disorders increases because the part of the body is used successively and without rest. The current study investigates the effect of 8 weeks of Kinesio Taping and sport program on grip ...

Methodology: This is an applied research in terms of purpose and a descriptive-survey research in terms of nature and type of research. The study population included all the employees and managers of the Libr...
Background and Aim: One of the most prevalent occupational diseases and conditions is musculo-skeletal disorders (MSDs) that impose expensive medical-recompense expenses, organic damages, and work-time wasting. The aim of this study was to detect spine curvatures (cervical, back/ low back, lumbar) and prevalence of musculo-skeletal disorders in assembly workers of Bahman automobile company, Teh...
this research presents a new application of the cloud theory-based simulated annealing algorithm to solve mixed model assembly line sequencing problems where line stoppage cost is expected to be optimized. this objective is highly significant in mixed model assembly line sequencing problems based on just-in-time production system. moreover, this type of problem is np-hard and solving this probl...
