Abstract Bacillus Calmette Guerin (BCG) immunotherapy is widely used for treatment of superfi cial bladder transitional cell carcinoma. Infectious complications while rare can be serious and severe disseminated infections as well as sepsis has been reported. There are no standard guidelines to direct therapy of these complications. Isoniazid is a commonly and widely used component of the various treatment regimens. Various strains of BCG are used for treatment of bladder cancer as well as vaccinations. These strains have evolved because of repeated subcultures in various laboratories in the world and have been shown to exhibit phenotypic… More >

Abstract Transurethral resection of the prostate (TURP) is the most common surgical intervention for benign prostatic hyperplasia (BPH), largely due to lower urinary tract symptoms refractory to medical therapy. TURP remains the gold standard for men with prostates sized 30g-80g, while open prostatectomy has been the preferred option for men with glands larger than 80g-100 g and those with other lower urinary tract anomalies such as large bladder stones or bladder diverticula. Unfortunately, these procedures have complications including bleeding (often requiring transfusion in 7%-13% of cases), electrolyte abnormalities (2% TURP syndrome), erectile dysfunction (6%-10%), and retrograde… More >

Abstract The IHX (Intermediate Heat Exchanger) of a VHTR (Very High Temperature Reactor) transfers 950° heat generated from the VHTR to a hydrogen production plant. The Korea Atomic Energy Research Institute (KAERI) has manufactured a small-scale prototype of a PCHE (Printed Circuit Heat Exchanger) under consideration as a candidate of the IHX. In this study, as a part of high-temperature structural integrity evaluation of the small-scale PCHE prototype, we carried out a macroscopic structural behavior analysis including structural analysis modeling and thermal/elastic structural analysis under small-scale gas loop test conditions as a precedent study to a More >

Abstract Optical profilers have been widely used in many areas of surface measurements and characterizations, measuring parameters such as surface roughness, transparent films and coating thickness, nano- and micro-size structures, form and shape of mechanical parts, flatness of wafer and so on. In this presentation, we will discuss a spectrum of 3D measurement techniques using optical profiler and its applications in R&D lab and industrial production lines. The developments of the techniques are mostly application oriented. They target some measurement challenges encountered in optical 3D metrology applications. These techniques include both software algorithm developments and hardware More >

Abstract The application of a particle method to incompressible viscous fluid flow problems is presented. The method is based on the MPS (Moving Particle Semi-implicit) scheme using logarithmic weighting function. Numerical results demonstrate the workability and the validity of the present approach through incompressible viscous fluid flow in a driven cavity and flow behavior in a liquid ring pump with rotating impeller blades.

Abstract The effects of the non-Newtonian blood viscosity on the wall shear stress (WSS) of the blood flows in stenotic right coronary arteries have been investigated by computer simulations. The numerical calculations were performed using the Newtonian Model and the non-Newtonian models with the fluid obeying the Power Law and the Carreau models for the simulations of unsteady blood flows. The differences on the spatial and temporal WSS distribution patterns due to the different blood properties were compared. The computational results demonstrate that the blood viscosity properties do not affect the spatial WSS distribution pattern qualitatively.… More >

Abstract The Stress distribution of contact area in engineering structure is complex. Automatic whole-field measurement of photo-elasticity is a feasibility method to solve the contact problem. However, the problem of isoclinic and isochromatic interaction is important in phase-shifting techniques in photo-elasticity. The technique named 8-step phase shifting technique is applied to solve the problem of isoclinic fringe pattern influenced by isochromatic fringe patterns in integer order and half-integer order. Isoclinic parameter in the range of [0,I/2] is given by the method.

Based on the eight-step phase shifting technique, some methods to determine the first principal stress… More >

Abstract The purpose of this talk is to provide an overview of the most recent theoretical studies undertaken by us in the field of hydrogen storage materials research. On selected examples, the application of our computational tool of choice, density functional theory, will be illustrated to show how ab initio calculations can be of use in the effort to reach a better understanding of hydrogen storage materials and to occasionally also guide the search for new promising approaches. Systems to be discussed include: Metal-organic frameworks, where we have studied hydrogen physisorption in three different types of… More >

Abstract LED has been used in optical system extensively, because of the power saving efficiently and excellent characters. Medical instrument is one of the important fields of LED application. For example, surgical light, dental operation light, etc have been developed in past few years. In this study, based on the specification ISO 9680: 1996 "Specification for Dental Operation Light", a compact LED dental operation light of linear layout is developed. The designed dental operation light consists of spheroid reflectors, collimating lenses, lens hoods, auxiliary reflectors and supporter accessories. The luminance of the light is over 35,000 More >
