—In this letter, we propose a novel residual echo suppression (RES) algorithm based on a statistical model constructed in the acoustic echo cancellation framework. In the proposed approach , all the possible near-end and far-end signal conditions are classified into four distinct hypotheses, and the power spectral density estimation is carried out according(More)
OBJECTIVE To investigate the long-term effects of complex decongestive therapy (CDT) on edema reduction in breast cancer-related lymphedema patients after axillary dissection, according to the initial volume of edema. METHODS A retrospective review of 57 patients with unilateral arm after an axillary dissection for breast cancer was performed. The(More)
OBJECTIVE To investigate any additional effect of dual transcranial direct current stimulation (tDCS) compared with single tDCS in chronic stroke patients with aphasia. METHODS Eleven chronic stroke patients (aged 52.6±13.4 years, nine men) with aphasia were enrolled. Single anodal tDCS was applied over the left inferior frontal gyrus (IFG) and a cathodal(More)
In this paper, we propose a novel residual echo suppression (RES) algorithm constructed in the acoustic echo canceller. In the proposed approach, we introduce a statistical model to detect the signal components of the output signal and the state of signal is classified into four distinct hypothesis depending on the activity of near-end signal and residual(More)
OBJECTIVE To obtain information on the socioeconomic, medical, and functional status of polio survivors, and to use these results as the preliminary data for establishing the middle-aged cohort of polio survivors. METHODS The subjects were recruited based on the medical records of multiple hospitals and centers. They were assessed through a structured(More)
PURPOSE To determine the 1-year survival rate, 1-year amputation-free survival rate and the risk factors of amputation for patients with diabetic foot ulcers. MATERIALS AND METHODS One hundred seventy-three patients with diabetic foot ulcers were included in our study. Mean patient age was 67.5 (range, 29 to 87, SD ±11.4) years. 74% of the patients were(More)
BACKGROUND Fractures which need urgent or emergency treatment are common in children and adolescents. This study investigated the incidence patterns of pediatric and adolescent orthopaedic fractures according to age groups and seasons in South Korea based on population data. METHODS Data on the number of pediatric and adolescent patients under the age of(More)
BACKGROUND Although ankle fracture surgery can affect glycemic control by either trauma-induced stress or a postoperative decrease in physical activity, there is little evidence on this issue. This study aimed to evaluate the influence of ankle fracture surgery on glycemic control and to assess the risk factors for poor glycemic control after surgery in(More)
PURPOSE This study investigated the correlation between isometric muscle strength, gross motor function, and gait parameters in patients with spastic cerebral palsy and to find which muscle groups play an important role for gait pattern in a flexed knee gait. MATERIALS AND METHODS Twenty-four ambulatory patients (mean age, 10.0 years) with spastic(More)
Human palatine tonsil-derived mesenchymal stem cells (TMSCs) are known to be a new source of progenitor cells. Using waste tissue after tonsillectomy as a cell provider can be the biggest benefit of TMSCs, compared with other stem cells. The purpose of this study was to investigate tenogenic differentiation of TMSCs and to access the differential effects of(More)
