Background: Shift work can cause problems for workers’ health, especially nurses. This study was done to assess the problems caused by shift work and the nature of the job in nurses of the educational hospitals of Kerman University of Medical Sciences, Iran. Materials and Methods: This was a descriptive study carried out in 2013. The research participants were 159 nurses with and without...

conclusions the study findings highlight the importance of the mental aspect of fatigue in this working group. these results have possible implications for workers’ health and well-being and for the design of shift work systems, for industrial workers. background shift work is a well-recognized occupational health hazard in both industrialized and industrially developing countries. prolonged wo...

BACKGROUND Previous studies have reported the effects of direction of shift rotation on sleep, however, the findings are inconsistent. In this study, we investigated sleep quality related to direction of shift rotation using large-scale data from shiftwork-specific health examinations of electronics workers. METHODS This study included 4750 electronics workers working in a rotating 3-shift sy...

We consider shift-invariant multiresolution spaces generated by rotation-covariant functions ρ in R2. To construct corresponding scaling and wavelet functions, ρ has to be localized with an appropriate multiplier, such that the localized version is an element of L2(R2). We consider several classes of multipliers and show a new method to improve regularity and decay properties of the correspondi...

BACKGROUND A capsular shift procedure has been described for the treatment of hip instability; however, the biomechanical effects of such a shift are unknown. PURPOSE To create a cadaveric model of hip capsule laxity and evaluate the biomechanical effects of a capsular shift used to treat hip instability on this model. STUDY DESIGN Controlled laboratory study. METHODS Eight cadaveric hips...

[Purpose] The purpose of this study was to determine the effects of a 4-week program of active condylar rotation exercise on the extent of the lateral mandibular shift during mouth opening in patients with temporomandibular disorder. [Subjects and Methods] Patients with temporomandibular disorder (n = 12; 7 men and 5 women) were recruited. The active range of temporomandibular motion was record...
