Location-based systems for indoor positioning have been studied widely owing to their application in various fields. The fingerprinting approach is often used in Wi-Fi positioning systems. The K-nearest-neighbor fingerprinting algorithm uses a fixed number of neighbors, which reduces positioning accuracy. Here, we propose a novel fingerprinting algorithm,(More)
In this paper, we develop the indoor navigation system based on PDR (Pedestrian Dead Reckoning) using various sensors in smartphone. Usually PDR is consisted of step detection, step length estimation and heading estimation. The issue of PDR is step length estimation and to enhance the accuracy of step length, we apply the walking status recognition(More)
This paper proposes a method for a synchronous reluctance motor (SynRM) which selects an appropriate stator d,q-axis current component combination (flux current, torque current) such that the influence of iron core loss on the developed torque can be minimized in torque control. A coupled finite element analysis and Preisach's modeling for SynRMs is(More)
Mesenchymal stromal cells (MSCs) are seen as an ideal source of cells to induce graft acceptance; however, some reports have shown that MSCs can be immunogenic rather than immunosuppressive. We speculate that the immunomodulatory effects of regulatory T cells (Tregs) can aid the maintenance of immunoregulatory functions of MSCs, and that a combinatorial(More)
The ultimate goal in treating zygomatic complex fracture is to obtain an accurate, stable reduction while minimizing external scars and functional deformity. The present authors present our experiences with a single transconjunctival incision and two-point (inferior orbital rim and frontozygomatic suture) fixation in 53 patients with zygomatic complex(More)
BACKGROUND/AIMS Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus. Similar to asthma, EoE can induce irreversible structural changes in the esophagus as a result of chronic and persistent eosinophilic inflammation. The aim of this study was to analyse changes in symptoms, eosinophil counts and endoscopic findings after(More)
INTRODUCTION Schinzel-Giedion syndrome (SGS) is a rare multiple congenital malformation syndrome defined by characteristic facial features, profound developmental delay, severe growth failure, and multiple congenital anomalies. Most individuals affected by SGS die in early childhood mainly because of progressive neurodegeneration and respiratory failure.(More)
(A) Patient with posttraumatic enophthalmos and hypoglobus of the right eye. (B) Upward gaze limitation was noted on preoperative day 1. A B or a nerve sheath injury whereas direct damage to the optic nerve during dissection and insertion of implant materials is also possible. We report a case of a patient with postoperative traumatic optic neuropathy due(More)
Massive weight loss results in skin excess, leading to an unsatisfying body contour. Various thigh lift procedures can correct flabby skin in the lower leg. We present a lower body contouring technique with a report on two patients. The procedure is determined by the body contour of the patient. As the skin excess in the thigh area tended to appear mostly(More)
There have been many attempts for regeneration of peripheral nerve injury. In this study, we examined the in vivo effects of non-differentiated and neuronal differentiated adipose-derived stem cells (ADSCs) in inducing the neuronal regeneration in the Sprague-Dawley (SD) rats undergoing nerve defect bridged with the PCL nanotubes. Then, we performed(More)
