The effect of oriental medicines an the growth of oral bacteria(B. pumilus JU4, B. coagulans JU6, B. subtilis var globigii JU7 and B. subtilis var. globigii JU9) which were isolated from teeth, gums and tongues of patients was investigated. lt was shown that the water extracts of Glycyrrhiza glabra L. var. glandulifera Regel et Zucc., Schizandrae Fructus and Coptidis Rhizoma have the strong antimicrobial activity against every test organism. Especially, the water extract of Schizandrae Fructus has the most antimicrobial activity against all test bacteria of which MIC were the same as 0.25%. The growth of oral bacteria B. pumilus JU4 was inhibited by addition of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma in the concentration of 0.9%, 0.2% and 0.1% respectively. It was tested that specific growth rates of B. pumilus JU4 in each concentration of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma. From the results, the test showed that mean of specific growth rates of B. pumilus JU4 decreased 102%, 186% and 210% in 3% concentration of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma more than those in control respectively.

Amid a flurry of publicity and lobbying, the United State has enacted a sweeping new act, known as the Sarbanes-Oxley Act of 2002, intended to regulate practices perceived to have resulted in recent accounting and other corporate abuses, and therefore to restore investor confidence in the US securities markets. The new Act applies to all companies whose securities are registered with the Securities and Exchange Commission(SEC) and which are required to file financial statements with the SEC. This includes many corporations not domiciled in the United States (so called foreign private issuers) whose securities trade publicly in the Unite Stated. The new Act establishes significant new disclosure regulations and will impose substantive rules of internal corporate governance including establishment of Public Company Accounting Oversight Board in areas not previously regulated by US federal authorities. The Act also requires chief executive officers and chief financial officers of registered issuers to certify the completeness and accuracy of their company's financial statements with the Sec. In addition, The new Act provides for substantial new regulation of the conduct of audits and in issuer's relationship with its public accounting firm and creates new criminal offenses for false executive certifications, securities fraud, the obstruction of justice, and actions against whistle blowers. It substantially increases the penalties for existing US criminal offences such as mail fraud and wire fraud.

We suggest a business model and it's system architecture for the mobile advertising by smart-phone that is new trend in recent ITC(information technology and communication) application. It will be a new marketing tool with an intelligent agency that connect between user and business company automatically. The business model is developed as an application of MIM(Mobile Interactive Marketing) technique. The model's key concept is CMI(Customer Managed Interactions) in which the customers and service companies are actively interchange their information simultaneously by the Agency Web Server. If a customer input information by a application(Agency Web Client) in his smart-phone, the information is transmitted to the Agency Web Server, and saved in the customer database. Also, a company, advertiser, input advertizing information about his products or services, the Agency get the information. The matching algorism search a target that satisfy the requirement of each. The Agency, intelligent mobile advertizing system, could more efficiently advertise to the proper target customers. The business model will contribute to the optimal target selection and sales promotion of the company.

An automobile hub is composed of a hollow cylindrical part with inner and outer diameters. These hub diameters must be precise, as any irregularities in them (diameters) can influence/degrade the motion of an automobile with this problem. Highly accurate and reliable hub inner and outer diameters measurement systems are therefore required for inspection of the diameters. In this research, an automobile hub inner and outer diameters measurement system has been developed and tested. The system consists of measuring heads with LVDT sensors, and associated software for automatic measurement and calibration of the diameters and the sensors respectively. The system has been evaluated in comparison with an existing measurement system, and the following outcomes have been achieved; ·Improved and guaranteed quality and reliability ·Increased productivity and cost reduction These results prove the system developed in this research to be suitable for automobile hub inspection.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Electro-rheological fluid is recently used for the micro polishing of 3-dimensional micro-aspherical lens. It's also used for polishing small area defects on the wide flat wafer. Since ER fluid shows a behavior of viscosity changing under certain electric fields, micro polishing efficiency may be enhanced for certain cases. In this paper, a perfluorinated carbonyl fluoride oil based ER fluids was used to improve surface polishing rate and submicron-scale accuracy. As the polishing electrodes, micro size cylindrical tools had been used for maximizing the electric field. An experimental device, which was applied for micro polishing a number of wafers of 4 inches in size and other workpieces, was made on a precision polishing system. It consisted of a steel electrode, a wafer fixture, 10mA current and DC 5kV power supply unit, and a controller unit. From the Experiments, the ER fluid is applicable for micro polishing of small parts.

A healthy 35-year-old man who was scheduled for closed reduction of nasal bone fracture developed atrial fibrillation during induction of general anesthesia after intravenous glycopyrrolate injection. During emergence of general anesthesia, atrial fibrillation was suddenly changed to paroxysmal supraventricular tachycardia with 200 beat per minute and lasted for about 10 seconds. Because blood pressure was stable, esmolol was used to reduce ventricular response. At recovery room, ventricular response reduction about 55 beat per minute was observed after intravenous injection of verapamil 5 mg. Thereafter, the rhythm was returned to normal sinus rhythm with bradycardia.

Transcatheter arterial chemoembolization (TACE) has become an effective alternative treatment strategy for patients with inoperable hepatocellular carcinoma (HCC). Although TACE is relatively safe, acute respiratory distress syndrome associated with pulmonary lipiodol embolism is a rare and potentially fatal complication. We report a rare case of acute respiratory distress syndrome after TACE for inoperable HCC. A 75-year-old man, with huge HCC in right lobe, was treated by TACE for the first time. Seven hours after uneventful TACE procedure, he felt dyspneic and his oxygen saturation recorded by pulse oximetry (SpO2) fell to 80% despite of applying non-rebreathing mask. He underwent mechanical ventilation with a protective ventilatory strategy. We experienced a case of acute respiratory distress syndrome after TACE for HCC.

This study is purposed to analyse the effects of long-term & one-time 10km running exercise from bone metabolic marker change on bone metabolism. 7 male members(18.6±1.08) from a marathon club were subjected to the study. They were allowed to do long-term 10 km running training once a week for 6 months. And bone metabolism mark was determined according to the respective times : before/after 6 months training, before/after 10 km race, one day after the race, 3 days after the race. The examination items of bone metabolism mark were serum calcium, phosphorus, paratyroid hormone, osteocalcin, calcitonin, alkaline phosphatase in blood and calcium, phosphorus, deoxypyridinolin in urine. The results of study were as follows; 1) There was no change in deoxypyridinolin and alkaline phosphatase but there was significant change in calcitonin, paratyroid hormone and osteocalcin(p<.01). 2) There was no change of Calcium in serum and urine but there was significant change of phosphorus in blood(p<.01). To make a conclusion, it is determined that long-term 10 km running at low intensity and low frequency tends to restrict bone metabolism circulation, but exercise at a little high level activates bone metabolism into building up bones and absorbing bones and finally shows up high bone metabolism circulation, which is inferred to have an effective influence on bone health. It is considered there is a possibility that different exercise intensity, even same kind of exercise, influences on bone metabolism sdifferently.
