BACKGROUND We describe a procedure for diagnosis and planning for orthognathic surgery based on international standards. A special 2D planning based on lateral cephalograms (Axis Orbital Marker Lines System) realize a transmission to the SAM 2P articulator (3D) by means of the Axis Orbital Plane. METHODS Former intraoperative measurement of the average height of the LeFort I osteotomy plane r...

OBJECTIVE Bariatric surgery is one of the fastest growing hospital procedures, but with a 40% complication rate in 2001. Between 2001 and 2005 bariatric surgeries grew by 113%. Our objective is to examine how 6-month complications improved between 2001 and 2006, using a nationwide, population-based sample. DATA/DESIGN: We examined insurance claims in 2001-2002 and 2005-2006 for 9582 bariatric s...

The German Society of Plastic and Reconconstructive Surgery DGPW takes pride in announcing the launch of our new scientific online journal "GMS Interdisciplinary Plastic and Reconstructive Surgery DGPW" at the beginning of our 50th anniversary. Our main focus has always been the interdisciplinary discussion of plastic and reconstructive aspects of surgery. DGPW today therefore represents 700mem...

In this paper, we present classroom strategies for teaching kinematics at middle and high school levels, using Rovio’s famous game Angry Birds and the video analyser software Tracker. We show how to take advantage of this entertaining video game, by recording appropriate motions of birds that students can explore by manipulating data, characterizing the red bird’s motion and fitting results to ...

In this report, we give an overview of research and development of serious video games. Firstly, we briefly look at the history of (digital) video game. We discuss different types of video game and introduce the concept of serious game. In the following, we review the important aspects of technology development for general video games and serious games. We further discuss the critical elements ...

An optimal commodity tax approach is taken to compare trade taxes and VATs when some commodities are produced informally. Trade taxes apply to all imports and exports, including intermediate goods while the VAT applies only to sales by the formal sector and imports. The VAT can achieve production efficiency within the formal sector, but unlike the trade tax regime, it cannot indirectly tax pure...

Locomotor activity (LMA) is a simple and easily performed measurement of behavior in mice and other rodents. Improvements in video tracking software (VTS) have allowed it to be coupled to LMA testing, dramatically improving specificity and sensitivity when compared to the line crossings method with manual scoring. In addition, VTS enables high-throughput experimentation. While similar to automa...

OBJECTIVE Using a mixed model design, this study examined the effects of interactive versus passive distraction on healthy preschool-aged children's cold pressor pain tolerance. METHODS Sixty-one children aged 3-5 years were randomly assigned to one of the following: interactive distraction, passive distraction, or no distraction control. Participants underwent a baseline cold pressor trial f...
