임승평 충남대학교 의과대학 지역사회의학연구소 1992 충남의대잡지 Vol.19 No.1

A comparative study for the prophylactic effect of TIENAM was performed on 20 patients receiving cardiac value replacement. There were statistical differences in leukocyte counts between control group and experimental (TIENAM using) group, especially on the operative day and on the fifth postoperative day. In experimental group, leukocyte count returned to normal range within three days after operation however, it remained out of normal range even beyond the fifth postoperative day in control group. There was no statistical significance in renal function study(BUN, Cr.) between two groups. There was no significant clinical side effect relating to TIENAM, except for a mild, transient erythema around the injection site.

A clinical analysis was performed on 182 cases of patients over 15 years of age who have undergone surgical correction of congenital cardiac malformation during the period of 8_1/2 years from April 1983 to November 1991, at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. During this period, 182 adult patients(27.3%) with a variety of congenital cardiac malformations, 148 acyanotic lesions and 34 cyanotic lesions, were operated on. Among them, male was 82 and female was 100. There were 67 patients under 20 years of age, 44 between 21 and 25 years, 21 between 26 and 30 years, 21 between 31 and 35 years, 10 between 36 and 40 years and 19 over 41 years. The most common anomaly was atrial septal defect which accounted for 61 cases(33.5 %) and other common anomalies were ventricular septal defect(29 cases, 16.0%), patent ductus arteriosus(29 cases, 16.0%) and tetralogy of Fallot(22 cases, 12.1%) in order of incidence. Overall operative mortality was 4.9%(2.0% in a cyanotic group and 17.7% in cyanotic group) in compare with 6.7% of total cases of congenital heart diseases during the same period. In conclusion, congenital heart disease in adults can be corrected with a satisfactory outcome, therefore an aggressive surgical approach should be mandatory.

A clinical analysis was performed on 177 patients receiving 185 mitral valve replacements during the period of 11 years from May 1983 to April 1994 at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The results of clinical follow-up until the end of September 1995 were as follows : 1. Sixty-six patients were male and one hundred and eleven patients were female and the age of patients varied widely from 12 to 66 years with average of 39.7 years. 2. Dyspnea on exertion and palpitation were the major preoperative symptoms. 3. On past-medical history, there were rheumatic fever (9.6%), thromboembolism (9.6%), previous mitral valve replacement (7.2%) and mitral valvuloplasty (3.3%). 4.

A Research on high School Physical Education Classes for the Effective Application of the 7th Curriculum This research was performed to provide the fundamental materials for the selection of the effective form and content of the newly curriculum as surveying the understanding for the overall physical education class with 576 college student experienced in their high school age. We obtained the four results as following. First, the experience of understanding about the meaning and purpose of physical education, boy students were mostly higher than girls. And also the percentage of interest, boy students were high. They recognized the reason that they fell interested in P.E. class was that it made them feel better. And the reason that they felt it painful was that it always demanded beyond their ability. Second, in the case of warm-up, the percentage of the answers that there had been teacher's instruction were the highest. The pattern of warm-up were the highest practiced in a proper way without particular way. And the experience of learning about the need of warm-up, the answers that they have not learned about the need in detail were high. In the case of cool-down, the answers that it had never been due after class were the highest, and it was not changed their feeling after cool-down. The answers were high that they had learned it a little in the experience of learning about the need of cool-down. Third, the answers were high that they didn't know how the physical grade was scored, and they recognized the physical grade was scored as distinguishing the students who did well and didn't. Finally the answers were high that high that they didn't we of the content they learned in the P.E. class. However the boy students like to play basketball and soccer, and the girls like to play badminton. It was the highest that the number of playing is 4 times a week and the time is one or two hours. Therefore they want forward to play swimming and tennis best.

A fiber optic magnetic sensor(FOMS) was made of single-mode optical fiber deposited Metglas cast alloy by using magneton sputtering. The matallic-glass-coated optical fibers were used as magnetic field sensing parts in one arm of a Mach-Zehnder interferometer. Inside a chamber containing Helmholtz coils which produced both a dc field and an ac field the sensing part was placed. the phase shift were measured as a function of the magnitude of the dc field and the frequency of the ac field. The phase shift amplitude to the magnitude of the ac field was measured to be 0.91rad/Oe, and a resonance enhancement factor of Q=95 was exhibited at the 245Hz frequency.
