The objective of this study was to evaluate the effect of heat treatment on bending properties in .016" Green Elgiloy wire and .016"x. .022" Blue Elgiloy wire. × Bending load and Bending deflection were measured with Instron type bending testing machine. The results were follows: Bending load and flexure modulus were progressively increased by heat treatment. Increased degree of bending load and flexure modulus by heat treatment were more effective by high temperature (500℃ and 600℃) than low temperature (300℃ and 400℃). Increased degree of bending load and flexure modulus by heat treatment were more effective by long time(6-9min) than short time(1-3min). The difference in bending load and flexure modulus between air cooling method and water cooling method were not clearly shown.

A Coloring and spectrophotometric method using tetrathiocyanatocobaltate(Ⅱ) ion as a complexation reagent was developed for the identification of Coptidis Rhizoma and Phellodendri Cortex in herb medicine. Identification tests could be carried out coloring in test tube and ultraviolet-visible spectrophotometry. Coptidis Rhizoma and Phellodendri Cortex: with a solution of 1,2-dichloroethane in thst tube - yellowish green. The ultraviolet - visible spectrum of base components in 1,2-dichloroethane exgibits maxima at 270, 340, 442 and 624nm and was developed for the determination of berberine or palmatine in Coptidis Rhizoma and Phellodendri Cortex. Optimum conditions for good determination was determined: Maximum wavelength 442nm; Determination of berberine was possible to the range of 0.01mg/ml-0.10mg/ml in 1,2-dichloroethane. Calibration curve showed that the coefficient of variation was 0.999% for berberine. And determination of palmatine was possible to the range of 0.10mg/ml - 0.60mg/ml in 1,dichloroethane. The method was rapid, accurate. It was considered that spectrophotometry could be greatly applied to the analysis of base components in Coptidis Rhizoma and Phellodendri Cortex containing relatively small amount of gerb medicine extract.

The emergence of antibiotic-resistant microorganisms is a worldwide problem and its clinical aspects are diverse among countries or clinics. Thus, for obtaining consistent data which could be used as a guide for proper usage of antimicrobial agents, we carried out present studies analyzing the total amount of antimicrobial usage, the proportions of the preventive usage and the therapeutic one, and the antimicrobial susceptibility of clinical isolates from Kangbuk Samsung Hospital. The amount of antimicrobial usage was investigated on the basis of "Individual Drug Day(IDD)" theory in 1,574 patients who had left the hospital in May, 1998. The antimicrobial susceptibility test was performed in the 1,885 isolates obtained for six months from blood samples or microorganism specimens. The usage rates for the individual antimicrobial agents were 43.0%(5579/12970 days) for cephalosporines, 38.3%(4968/12979 days) for aminoglycosides, 12.7%(1643/12979 days) for penicillins (including β-lactam inhibitor complexes), 3.9%(507/12979 days) for quinolones, 0.96%(125/12979 days) for glycopeptides, 0.86% (112/12979 days) for monobactams, and 0.11% (15/12979 days) for carbaphenems, respectively. The total usage amount of antimicrobial agents administered by injection was determined as IDDs/1000 inpatients/day. The results showed that the usage day for the individual antimicrobial agents for 1,000 inpatients a day was 266, which means that the average rate of the patients under antimicrobial treatment by injection a day was 26%. In the susceptibility tests, MRSA was isolated from both blood culture tests and general microorganisms tests at high frequencies, 62% and 70%, respectively. The data furthermore suggests that more attention needs th be paid to vancomycin-resistant S. aureus (VRSA). Of 1007 cases receiving antimicrobial treatment by injection, the usage was for the purpose of prevention in 406 cases (40.3%) and 599 cases (59.5%), including the empiric antimicrobial treatment, were therapeutic treatment. We speculate that the guideline for antimicrobial usage needed to be revised, with a management in order, on the basis of our investigations for decreasing the antimicrobial resistant incidence rates and managing the DRG in advance.

Warfarin is used in patients with pulmonary embolism, deep vein thrombosis (DVT), artificial cardiac valvular disease by preventing production of embolism but can cause severe problems when adverse effects occur. Anticoagulation services (ACS) have practiced in U.S.A. from 1960's and is now actively being practiced at Kangdong Sungsim Hospital, Seoul National University Hospital and Samsung Seoul Hospital in the country. This hospital practiced to twenty out-patients who's INR(international normalized ratio) is out of normal range for three months from June to August. As a result of ACS, all of twenty patients became to maintain INR with in therapeutic range compaine to previous values and adverse effect such as bleeding became to decrease. Regular monitoring through ACS resulted in effect to patients who have received a anticoagulant agent.
