IntroductionSurgeons are one of the most significant jobs in health care system that plays an important role patients' promotion and their treatment. In current study, effect mental workload on work performance surgeons was tested by considering mediating fatigue this relationship.MethodThis study done analytically 165 working operating rooms hospitals Iran. To determine workload, SURG-TLX meth...

We present a new determination of the metallicity distribution, age, and luminosity function of the Galactic bulge stellar population. By combining near-IR data from the 2MASS survey, from the SOFI imager at ESO NTT and the NICMOS camera on board HST we were able to construct color-magnitude diagrams (CMD) and luminosity functions (LF) with large statistics and small photometric errors from the...

In this study, we examine the effect of church tax on the church membership decision using Finnish data. We present both descriptive statistics from an opting-out website and econometric evidence exploiting the panel structure of a large individual-level data set. Our descriptive analysis shows that opting out is concentrated towards the last days of the year, i.e., the last chance to avoid pay...

We present the results of a study performed with the goal to investigate whether low-mass pre-main sequence binary stars are formed by multiple fragmentation or via stellar capture. If binaries form preferentially by fragmentation, we expect their disks to be co-planar. On the other hand, the capture scenario will lead to a random distribution of disk orientations. We performed near-infrared po...

We present a framework for studying the relation between the distributions of income and house prices that is based on an assignment model where households are heterogeneous by incomes and houses by quality. Each household owns one house and wishes to live in one house; thus everyone is potentially both a buyer and a seller. In equilibrium, the distribution of prices depends on both distributio...

Networked embedded systems are expected to support adaptive streaming audiohideo applications with soji real-time constraints. These systems can be designed in a cost efficient manner only if their architecture exploits the “leads” suggested by clever compiletime performance estimators. However; performance estimation of networked embedded systems is a non-trivial problem. The computational req...

* Th e papers collected here are based on presentations at the International Conference on Reference and Discourse Structure , which was organized by Sofi ana Chiriacescu and Klaus von Heusinger at the University of Stuttgart (January 15-17, 2010). We thank all participants of the conference for the lively and constructive discussion and all contributors for writing up their research results fo...

The bipolar reflection nebula OH 231.8+4.2 (OH 0739-14) centred on the Mira variable star QX Pup has been mapped at KS in linear polarization using the ESO SOFI near-infrared multi-mode instrument. The large scale linear polarization features agree with previous studies, validating the polarimetric mode of the instrument. However the high spatial resolution of the polarization map reveals consi...
