We present new closed-form expressions for analysis of Teng-Man measurements of the electro-optic coefficients of poled polymer thin films. These expressions account for multiple reflection effects using a rigorous analysis of the multilayered structure for varying angles of incidence. The analysis based on plane waves is applicable to both transparent and(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)
PURPOSE 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(More)
In the last few years there has been a tremendous increase in connectivity between systems which has brought about limitless possibilities and opportunities. Unfortunately security related problems have also increased at the same rate. Computer systems are becoming increasingly vulnerable to attacks. These attacks or intrusions based on flaws in operating(More)
We present a simple optical arrangement for phase sensitive detection of degenerate four-wave mixing (DFWM) to characterize the real and imaginary parts of Chi((3)) using an imaged 2-D phase grating. Phase sensitive coherent detection of DFWM signal is demonstrated. Phase stabilization of the interferometric arms is obtained passively with the 2-D grating.(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)
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 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)
The goal of this thesis is to re-evaluate both Teng-Man and attenuated total reflection (ATR) methods for measuring the linear electro-optic (EO) coefficients of poled organic thin films based on a multilayer structure containing a transparent conducting oxide (TCO) layer. The linear EO properties are often characterized using the Teng-Man reflection(More)
