Aims: Neck pain is a common disorder among computer users that can reduce the personal yield. So the prevention of it is an important matter in computer users. The purpose of this study was to evaluate the effect of a period of exercise therapy and an ergonomic intervention on chronic neck pain and disability among computer users.
Materials & Methods:In this quasi-experimental cross-sectional study in 2012, 30 female computer users of Lorestan University of Medical Sciences with at least 6 months experience of neck pain were selected purposefully by a demographic questionnaire. Subjects were located in experimental (n=15) and control (n=15) groups. The experimental group received therapeutic exercises and ergonomic intervention for two months but control group received no therapeutic intervention. The rate of neck pain and disability was measured by chronic neck pain and disability index questionnaire before and after of exercise therapy and ergonomic intervention. Data were analyzed by independent T test and Pearson correlation coefficient in SPSS 16 software. Findings: There were significant differences between mean of chronic neck pain and disability scores of the two groups (p<0.05). But there were no significant relationships between neck pain, disability and the subjects' work experience. Conclusion: Exercise therapy along with ergonomic intervention is useful for treatment of chronic neck pain.
To achieve a successful architectural project, it is essential for architects to truly understand and collaborate with other designers and engineers during the whole project. Regarding daylight analysis, what architects decide about the fenestration types, sizes, and their placements, interior layout design, interior or exterior materials, and finally the outer shape of the buildings may change the quantity and quality of natural light in the interiors. Moreover, such decisions about room configurations, fenestration, and materials can also directly or indirectly affect thermal comfort which is needed to be checked and confirmed by energy experts in the project. In this paper, a newly developed digital solution, and a new plugin called AftabRad is introduced. Its main goal is to export the 3D model from the BIM Modeling software to Radiance, as its daylight simulation core, and present the results back to the BIM software. This plugin can help daylight specialists to be fully or partially involved in any projects to assist architects or urban designers to easily calculate different types of static or dynamic daylight metrics by themselves. However, daylight specialists can do daylight calculations in the final stage or the project if it is needed. In such a project, since most of the daylight analyses for different types of alternatives can be done by architects, and regarding the nature of BIM-based project, by having direct dialogs with energy experts, the probability of achieving a well-daylit space, being thermally and visually comfortable, and fulfilling the daylight requirements can be much higher in comparison with doing daylight simulation just at the end of a project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
