Treatment of cirrhotic patients with spontaneous peritonitis using antibiotics occasionally fails. Fungal infections may be one of the causes of antibiotic treatment failure in such patients. In this study we evaluated the clinical significance and characteristics of spontaneous fungal peritonitis (SFP). Consecutive cirrhotic patients with spontaneous(More)
It has recently been reported that interleukin-4 (IL-4) is required for the production of IgE, and anti-IL-4 monoclonal antibody (mAb) inhibits in vivo IgE responses. These suggest that blocking of IL-4 activity may be useful for the prevention or treatment of immediate hypersensitivity disorders. In this study we investigated whether anti-IL-4 has a(More)
Little is known about the prevalence of naturally acquired IgG antibodies to the capsular polysaccharides of Streptococcus pneumoniae (pneumococcal IgG) in Korea. In the present study, we investigated transplacental transfer and age-related levels of pneumococcal IgG to provide background seroepidemiologic data for S. pneumoniae in Korea. One hundred thirty(More)
In this paper, we show a controller design method for a class of discrete-time nonlinear systems described in T-S(Takagi-Sugeno) fuzzy model, which has uncertainties in state and input. The robust and non-fragile fuzzy H<sup>&#x221E;</sup> controller is designed based on Lyapunov function theory, PDC(Parallel Distributed Compensation) and PLMI(More)
In this paper, we describe the controller design method for nonlinear radar gimbal stabilization system with time-delay with polytopic uncertainty. In order to consider nonlinearity of the gimbal bearing frictional torque, we represent T-S fuzzy model for the nonlinear gimbal system. And the represented model can be rewritten as Parameterized Linear Matrix(More)
