Study Objectives : In the past, measurement of cardiac enzymes(i.e. CK and/or CK-MB, GOT, LDH)and myoglobin, cardiac specific serum troponin-T were widely used for the diagnosis of acute myocardial infarction, but it need a long time and have low specificity. Thus new diagnostic modality, TROP-T?? Rapid Assay, is very easy and rapid qualitative methods, is needed for the early detection of acute myocardial infarction. Methods : Total CK, GOT, LDH, myoglobin and serum troponin-T activities were measured in patients presenting with acute chest pain at the emergency department and at the same time TROP-T? Rapid Assay was done. Final diagnosis and diagnostic usefulness was evaluated. Results : Overall diagnotic sensitivity and specificity of initial results were as follows; TROP-T? Rapid Assay, 77.3, 100.0; myoglobin, 63.6, 70.4; CK, 95.5, 96.3; GOT, 86.4, 96.3; LDH, 90.9, 92.6; serum troponin-T, 86.4, 96.3, respectively. Conclusion : The TROP-T?? Rapid Assay is simple method and has a short time and nearly same sensitivity and specificity compared to other cardiac enzymes. Thus this is considered useful method in the early detection of acute myocardial infarction at emergency department.

Study objectives: To compare the quality of CPR provided by medical students and pre-EMTs perfoming three-rescuer CPR with that achieved by same students trained to provide standard two-rescuer CPR and to find the most effective method of resuscitation and to educate this methods to students. Material and methods: From July 1 to September 30, 1996, we had trained 60 groups consisted of the medical students, students of EMS technology and pre-EMT. Each group practiced two-rescuer CPR and three-rescuer CPR for 120 minutes with Resusci? Anne and perfomed CPR for at least 3 minutes without feedback. To eliminate any visual cues of perfomance the mannequin's recorder was hidden. Each actions were recorded by Resusci? skillmeter and Laerdal printer. To compare the quality of two-rescuer CPR and three-rescuer CPR, we analyzed the data by SPSS with paired t-test. Results: Three-rescuer teams delivered a mean minute ventilation and a mean minute cardiac compression substantially greater than that produced by two-rescuer teams(11.30±1.85 vs 9.09±2.22, p<0.001; 99.22±12.42 vs 95.12±15.75, p<0.001). Three-rescuer teams produce the more correct actions in chest compression and ventilation(93.84±7.56% vs 83.49±16.94%, 90.90±9.33% vs 77.00±17.06%). Conclusion: Three-rescuers can produce better CPR than two rescuers when a bag-valve-mask devices is used and the technique is easily learned and readily retrained, so we think that repeated education and training of this CPR methods to students is needed.

The Organ Injury Scaling Committee of the American Association for the Surgery of Trauma recently published a consensus classification of hepatic and splenic injuries. The hepatic and splenic injury scales, based on parenchymal laceration and intrahepatic hematoma, include grade 1 to 6 and grade 1 to 5 respectively, representing the least to most severe injury. Forty-eight patients with hepatic and splenic injury were evaluate by abdominal CT from January 1995 to May 1996 and we compared abdominal CT grading with operative grading. Four CT grades did not correlate with operative finding. CT grading showed a sensitivity of 80%, specificity 80% in regard to operative grading. We conclude that 1) CT is an accurate technique to determine the extent of hepatic and splenic injury. 2) CT grading of hepatic and splenic trauma has a high correlation with operative grading.

Study objective: To recognize importance of pain management in ED and properly manage the ED patients complaining pain by analyzing the intervals between arrival time in ED and pain medicine starting time, the types and the administered routes of pain medicine. Design: Retrospective review of ED charts Setting: University teaching hospital Participants: The patients had admitted in ED of Yeungnam University Hospital with a chief complaint of acute abdominal pain or pain due to bone fracture between June 1, 1995 and December 31, 1995. Results: The study group consisted 256 patients, 161 of them female. ED administrations of analgesics were 103 cases, 17 of them administered more than two times. The average time interval between arrival time and medication time was 169.02±120.25 minutes. Each types of perceived analgesics were antispasmodics 55 cases(53.40%), NSAID 26 cases(25.24%) and opioid 19 cases(18.45%). Every analgesics were administered through intramuscular routes, except only 3 cases. Violences of patients or relatives due to delayed pain control were occured 32 cases, 5 cases of them self-discharged and looked for other hospitals. Conclusion: Emergency physicians including interns and residents delayed management so long and ordered inappropriate administration routes and types of analgesics. So we thought proper protocols about pain management in ED were established.

In recent, due to the advanced development of the power semiconductor devices, the digital simulation becomes essential in order to investigate the behavior of the sytem before the manufacturing of the system by using computer for design and analysis of power electronic systems. This paper develops the program, so-called PECA, which can be applied for the power electronic circuits composing of power transistors, thyristers, GTO's and power FET, etc.. Also, the method of using computers for the analysis of power electronic circuits is considered. Finally, we consider both transistor DC chopper circuit and thyristor bridge circuit and prove the effectiveness of the program by both the experiment and simulation.

A synchronous motor started as an induction motor must be synchronized as soon as possible by the application of field at any point. Unfortunately, the dynamic motion equations, describing the synchronized process, that is, describing the pulling-into-step process, are represented by complicate and nonlinear differential equations which have no analytical techniques. However, practical criteria for predetermining with adquate accuracy whether a given motor will or will not pull into step under specified conditions, must be necessarily given. Futhermore, it is impossible to obtain the accurate solution of the closed form by conventional techniques. Even though they are obtained, they does not show the stable regions over 4 quadrants. Specially, the accurate observations about the continuous variations of slip and load angle are very important for the stablized control of synchronous motor and all systems with them. The abnormal and unstable operations such as hunting pulling out and etc. are fatal to the life of machine itself and all systems with them. Therefore, in this paper, the stable regions in the sense of strictness over 4 quadrants, the analytical and the experimental techniques, for cylindrical synchronous motor are introduced in detail. These techniques used in this paper are based on the construction and analysis of Liapunov function, derived from the Lagrange-Char-pit method which is one of the solution techniques for partial differential equations. The theory of the various stable regions and optimal points for applications of field, which can be predicted the success or the failure of pulling-into-step under the variations of load ratio and damping ratio is presented and also is proved by experimental results.
