Caregiving of cancer patients is burdensome and is likely to affect health behavior and outcome of caregivers. However, there are only a small number of studies on lifestyle behavior and use of preventive services by caregivers of cancer patients, especially in Asian populations. The aim of this study was to compare the status of lifestyle behavior and use(More)
BACKGROUND It is well known that cancer greatly affects not only patients but also their families. However, few studies on caregivers' quality of life have been conducted within the Asian population. METHODS We carried out a survey using well-constructed, self-administered questionnaires that were answered by pairs of patients with cancer and their(More)
BACKGROUND/AIMS To identify the predicting factors of present hepatitis C virus (HCV) infection among patients with positivity for antibodies to HCV (anti-HCV). METHODS We analyzed patients who showed positive enzyme immunoassay (EIA) results and performed an HCV RNA test as a confirmatory test at Kyung Hee University Hospital at Gangdong from June 2006(More)
A uterus-like mass (ULM) is a central cavity lined by endometrial glands and stroma and surrounded by thick-walled smooth muscles. To date, 31 cases of ULM have been reported in the English literature. ULM typically presents as a single mass and is located in the pelvic cavity. We report here a very rare case of multiple extrapelvic ULMs involving the(More)
A 61-year-old man presented to the emergency room with significant weight loss. Laboratory analysis revealed elevations in blood urea nitrogen, creatinine, and white blood cell count. Computed tomography imaging showed a large, infiltrative mass in the right renal vein, with metastasis to the brain. Biopsy of soft tissue mass and kidney revealed positive(More)
BACKGROUND AND AIM The anti-inflammatory effects of liquiritigenin, a major flavonoid isolated from Glycyrrhizae uralensis, have been reported in many inflammation models. However, its protective effects have not been reported in a colitis model. This study investigated the anti-inflammatory effect and mechanism of liquiritigenin for trinitrobenzene(More)
In this paper, we propose a new broadcasting scheme, called P2P broadcasting, for eliminating the service latency time of the existing broadcasting schemes. Our broadcasting scheme is based on the simplest staggered broadcasting protocol and then we use peer to peer caching technique, in which a number of clients that share a segment of a stream delivered(More)
We have demonstrated balanced coherent detection using distributed balanced traveling-wave photodetectors integrated with single mode polymer optical waveguides. Balanced distributed traveling-wave photodetectors having 3 dB bandwidth of 20 GHz exhibited 20 dB signal to noise ratio improvement measured at 15 GHz modulation frequency in a balanced coherent(More)
