OBJECTIVE The purpose of this study was to demonstrate the ultrasonographic (US) findings of rupture and the healing process of the medial head of the gastrocnemius ("Tennis Leg"). MATERIALS AND METHODS Twenty-two patients (age range: 30 to 45 years) with clinically suspected ruptures of the medial head of the gastrocnemius were referred to us for US(More)
A nanoelectromechanical (NEM) switching device is developed with a new technique involving a liquid medium. Operation voltage is reduced by about 40% and the number of switching cycles with reliable device performance is improved dramatically, more than 5-fold. The device has a 50 nm thick TiN cantilever with a 40 nm air-gap. A CMOS compatible process is(More)
Behςet’s disease (BD) is a multisystem disorder characterized by vasculitis. Pulmonary vascular problems such as pulmonary artery aneurysms (PAA) are reported to indicate poor prognosis and high mortality. We describe a 43-year-old man who presented with life threatening bilateral PAA and thromboembolic disease due to BD. He was treated with prednisone and(More)
This study was performed to investigate the relationship between dietary factors and asthma in a representative population-based sample of 19,659 men and women, aged 19-64 years, using data from the fourth and fifth Korean National Health and Nutrition Examination Survey (KNHANES), 2007-2011. The presence of asthma was based on self-reported physician(More)
In this paper, we propose a new graph sampling method for online social networks that achieves the following. First, a sample graph should reflect the ratio between the number of nodes and the number of edges of the original graph. Second, a sample graph should reflect the topology of the original graph. Third, sample graphs should be consistent with each(More)
We evaluate the efficacy and safety of single anterior screw fixation in the treatment of types II and III (Anderson and D'Alonzo classification) odontoid process fractures, and analyse our surgical results. From May 1996 to October 2003, 16 patients underwent single anterior screw fixation for type II (n=12) and III (n=4) odontoid process fractures and had(More)
The copper(II) isonicotinate (Cu(4-C5H4N-COO)2(H2O)4) coordination polymer was prepared, characterized and explored as sorbent for flow injection solid-phase extraction on-line coupled with high-performance liquid chromatography (HPLC) for determination of trace polycyclic aromatic hydrocarbons (PAHs) in environmental matrices. Naphthalene, phenanthrene,(More)
Osteoporosis associated with estrogen deficiency is defined as an abnormal decrease in bone mass leading to an increased fracture risk. Genistein (GEN), as a phytoestrogen, is a type of soybean-derived isoflavone that possesses structural similarity to estrogen. In this study, we assessed the effect of GEN in ovariectomized (OVX) mice. To determine the(More)
Integrated starter and generator (ISG) is working as starter after vehicle idle stopping and generator during vehicle driving. When ISG works as starter to operate engine, ISG produces maximum power at the operating speed 4000 rpm to remove vibration of initial starting of the engine. In that time ISG produces whine noise which can be detected inside a(More)
Irreversible demagnetization which occurs in permanent magnet (PM) due to high temperature is main issue in design of traction motor for hybrid electric vehicle. In order to prevent irreversible demagnetization, eddy current loss in PM should be minimized. This paper deals with the optimum design to reduce eddy current loss in PM. Indirect method is used to(More)
