Purpose: To investigate associations between computer use data and sleep quality among university students. Materials and Methods: This descriptive, cross-sectional study was performed on 312 students of Tehran University of Medical Sciences, Iran. Data was collected using Epworth Sleepiness Scale (ESS), Insomnia Severity Index (TSI), Pittsburgh Sleep Quality Index (PSQI), and a background...

The functions of Computable Analysis are defined by enhancing the capacities of normal Turing Machines to deal with real number inputs. We consider characterizations of these functions using function algebras, known as Real Recursive Functions. Bournez and Hainry 2006 [5] used a function algebra to characterize the twice continuously differentiable functions of Computable Analysis, restricted t...

With sound level meters the measurement uncertainty is fixed and transparent, depending on the class of the instrument. The counterpart of the measurement, the noise simulation, has many more uncertainties. The uncertainties stem from the calculation standard used, the application of the model’s theoretical basis in a computer program and the construction of the data model. The uncertainty of t...

the purpose of this study was to determine computer and internet use in agricultural extension by extension workers (ews). this study used a descriptive-correlational design.population for the study consisted of all extension workers (n= 320) in isfahan province, iran. a stratified sampling technique and census was used to select ews (n = 200). overall, findings indicate that ews have access to...

dry eye is the major contributor to computer vision syndrome. the reductions in the blink rate and amplitude have been considered as the possible mechanisms leading to this condition. the purpose of this study is to evaluate the changes in the lower tear meniscus heights and areas in the computer reading task, in dry eye subjects, with and without soft contact lenses. in this quasi-experimental...
