  • In the continuous casting process, mold level fluctuation Is the major cause of the surface and sub-surface defects. In the No.3 bloom continuous caster at Kobe Works, we ensured that the major cause of mold level fluctuation was mechanical hysteresis which existed in the driving system of mold level control. Moreover, we found out that it was possible to greatly Improve the stability of mold level by estimating this mechanical hysteresis and compensating It on-line. As a result of applying a new level control system based on this method, we got accurate control over good stability.

  • To realize high-speed intrusion detection by accommodating many regular expression (regex)-based signatures and growing network link capacities, we propose the Service TimE-Aware Load-balancing (STEAL) algorithm. This work is motivated from the observation that utilization of a many-core network intrusion detection system (NIDS) is influenced by unfair computational distribution among many-core NIDS nodes. To avoid such unfair computational distribution, STEAL is designed to dynamically distribute a large volume of traffic among many-core NIDS nodes based on packet service time, which is represented by the deep packet time in many-core NIDS nodes. From experiments, we show that compared to the commonly used load-balancing algorithm based on arrival rate, STEAL increases the number of received packets (i.e., decreases the number of dropped packets) in many-core NIDS. Specifically, by integrating an open source NIDS (i.e. Bro) with STEAL, we show that even under attack-dominant traffic and with many signatures, STEAL can rapidly improve the performance of many-core NIDS to realize high-speed intrusion detection.

  • Purpose: Subclavian steal refers to the retrograde flow of blood in a vertebral artery that supplies t ipsilateral shoulder and arm caused by proximal subclavian artery stenosis or occlusion. T purpose of this exhibit is to demonstrate MR findings of subclavian steal on contrast-enhanc 3D (CE 3DMRA) and 2D TOF MR angiography. Method: Four patients(men 3 and women 1, age: 28-78years) with subclavian steal obtained both CE 3DMRA and digital subtraction angiography(DSA) including subclavian arterie Sequential imaging was undertaken during first pass after double dose of Gd-DTPA (0 mM/kg) Injected by a power injector. Coronal source images were obtained with coronal D-fast low angle shot sequence(TR/TE/flip angle=3.8/l.3/35, acquisition time= 10sec/one measurement). Precontrast imaging was subtracted from enhanced images and maximu intensity projection was done. 2D time-of-flight MR angiography(2D TOF) of the carot bifurcation was added in all cases with post-saturation. All studies were review retrospectively.

  • The occurrence of subclavian steal syndrome is possible in patients with either severe stenosis or occlusion in the left proximal subclavian or brachiocephalic arteries. Limited and insufficient blood flow in the vessel with a lesion induces blood supply from the opposite side via any of the connected vessels, which is called a subclavian steal phenomenon. The duplex sonography is useful for detecting this phenomenon. Some patients who experience this phenomenon complain of vertebrobasilar insufficiency, such as headache or numbness and weakness in the arm, and so on. Subclavian steal syndrome means subclavian steal phenomenon accompanied by these symptoms. We present a patient with focal severe stenosis of the brachiocephalic artery, manifested as blood flow reversal in the vertebral, and a "to-and-fro" waveform pattern in the external carotid, internal carotid, and common carotid arteries.

  • In this paper, we propose virtual building construction plans. For this, we compose the construction materials with components and assemble components in pattern. When we change assembled constructions, we can design the building efficiently with patterns if the parts are selected. Also through information analysis of material components or patterns, we can provide information which is necessary to a reconstruction to the designer. Using steal house method, the assembly functions were comprised of a wall, a room, a window, a door, roof etc. Also We explained the materials automatic extraction method which applies steal house.

  • Subclavian steal syndrome is a type of obstructive artery disease caused by severe stenosis and occlusion of a left proximal subclavian artery or brachiocephalic trunk. The resulting vertebro-basilar insufficiency symptoms are due to retrograde blood flow from the contralateral vertebral and basilar arteries into the low-pressure ipsilateral upper extremity vessels. For that reason, patients usually experience dizziness or arm ischemic symptoms. Neurointervention is an effective treatment for ischemic stroke, including the subclavian artery stenosis. This paper reports a patient with subclavian steal syndrome who had a vertebral artery Doppler waveform change in duplex sonography and a 12 mmHg difference in interarm systolic blood pressure. A stenotic lesion of the subclavian artery was treated effectively by inserting a precise stent. The follow up examination showed that the vertebral artery Doppler waveform change disappeared and recovered and that the 12 mmHg difference in interarm systolic blood pressure decreased to 5 mmHg after treatment.

  • Based on the huge baseball game records, the steal plays an important role to affect the result of games. For the research about success or failure of the steal in baseball games, logistic regression models are developed based on 2007 Korean professional baseball games. The analyses of logistic regression models are compared of those of the discriminant models. It is found that the performance of the logistic regression analysis is more efficient than that of the discriminant analysis. Also, we consider an alternative logistic regression model based on categorical data which are transformed from uneasy obtainable continuous data.

  • Right aortic arch with isolation of the left subclavian artery is a rare anomaly. The incidence of bilateral ductus arteriosus is sporadic, and a right aortic arch with isolation of the left subclavian artery in association with bilateral ductus arteriosus is therefore extremely rare. Since the symptoms and signs of isolation of the left subclavian artery can include the absence or underdevelopment of the left arm, subclavian steal syndrome, or pulmonary artery steal syndrome, the proper therapeutic approach is controversial. We report a case in which surgical reconstruction was used to treat isolation of the left subclavian artery with right aortic arch in association with bilateral ductus arteriosus and a ventricular septal defect.
