No. 11106 Title OUTCOMES AFTER FLAP RECONSTRUCTION FOR EXTREMITY SOFT TISSUE SARCOMA: A CASE-CONTROL STUDY USING PROPENSITY SCORE ANALYSIS Authors Seungcheol Kang, Han-Soo Kim, Ilkyu Han Institution Department of Orthopaedic Surgery, Seoul National University Hospital, Seoul, Korea Abstract Background Limb-preserving surgery has become the standard of treatment for extremity soft tissue sarcoma...

the self-talk is one of psychological interventions that can be effective on improving and success in the motor performance and sport performance. so, the aim of the present study was to investigation effectiveness the motivational self-talkon secondary task performance (discrimination reaction time). 30 subjects have participated of the 160 students studying at the undergraduate from faculty o...

Many scientists in the field of x-ray imaging rely on the simulation of x-ray images. As the phantom models become more and more realistic, their projection requires high computational effort. Since x-ray images are based on transmission, many standard graphics acceleration algorithms cannot be applied to this task. However, if adapted properly, the simulation speed can be increased dramaticall...

A number of interrelated factors can affect the precision and accuracy of lung nodule size estimation. To quantify the effect of these factors, we have been conducting phantom CT studies using an anthropomorphic thoracic phantom containing a vasculature insert to which synthetic nodules were inserted or attached. Ten repeat scans were acquired on different multi-detector scanners, using several...

The amount of time allocated to vigilance, foraging, and locomotion as a function of group size were studied in the quokka (Setonix brachyurus), a small, moderately social, macropodid marsupial, on Rottnest Island. Despite living in isolation from most predators for up to 7000 years, quokkas exhibited typical group size effects of aggregation: they foraged more and showed less visual vigilance ...

Phylogenetic tree reconstruction is a fundamental biological problem. Quartet amalgamation combining a set of trees over four taxa into a tree over the full set stands at the heart of many phylogenetic reconstruction methods. This task has attracted many theoretical as well as practical works. However, even reconstruction from a consistent set of quartet trees, i.e. all quartets agree with some...

One of the most striking aspects of animal groups is their remarkable variation in size, both within and between species. While a number of mechanistic models have been proposed to explain this variation, there are few comprehensive datasets against which these models have been tested. In particular, we only vaguely understand how environmental factors and behavioral activities affect group-siz...

Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...

ABTRACT Background: In nuclear medicine, phantoms are mainly used to evaluate the overall performance of the imaging systems and practically there is no phantom exclusively designed for the evaluation of the software performance.  In this study the Hoffman brain phantom was used for quantitative evaluation of reconstruction techniques. The phantom is modified to acquire t...
