STUDY DESIGN A retrospective study of 58 patients undergoing cantilever transforaminal lumbar interbody fusion (c-TLIF). OBJECTIVES To evaluate morphologic changes in the intervertebral foramen (IVF) on the side contralateral to spacer insertion in patients undergoing c-TLIF using plain x-ray films and computed tomography scan. SUMMARY OF BACKGROUND(More)
OBJECTIVE To investigate clinical and radiological differences between joint destruction in the wrist and the feet in patients with RA. METHODS A cross-sectional clinical study was conducted in an RA cohort at a single institution. Clinical data included age, sex and duration of disease. Laboratory data included sero-positivity for anti-cyclic(More)
While pervasive technologies explore new gaming styles, traditional games, such as cards and tabletop games are still appealing and have various irreplaceable flavors. We point out that tangible game objects and spatial interactions amplify emotional impacts in gaming; and the advantage cannot be reproduced in completely digitalized games. Thus we propose(More)
The farside gravity field of the Moon is improved from the tracking data of the Selenological and Engineering Explorer (SELENE) via a relay subsatellite. The new gravity field model reveals that the farside has negative anomaly rings unlike positive anomalies on the nearside. Several basins have large central gravity highs, likely due to super-isostatic,(More)
The augmented reality (AR)-based learning support has several advantages over virtual reality or PC applications. AR enables to maintain the physical interaction that an activity originally offers, thus the skills and knowledge acquired in an augmented learning process can be intuitively applied to practice use. Whereas lots of AR-based self-learning(More)
In this demonstration, we introduce the augmented calligraphy system that aims at supporting a calligraphy learner's self-training process by giving feedback. In order to write characters well, body posture is a very important factor. However, it is difficult to keep proper posture without any assistance. Therefore, the system monitors the learner's posture(More)
STUDY DESIGN In vivo measurement of lumbar foramen using computed tomography and an axial loading device in healthy young subjects. OBJECTIVE To investigate the effects of axial loading on the morphology of the lumbar foramen in vivo. SUMMARY OF BACKGROUND DATA In vitro studies have shown morphologic changes in the lumbar foramen in response to axial(More)
