1.Clinical Electrophysiological Studies on the Chronic Recurrent Sustained Ventricular Tachycardia.
Korean Circulation Journal 1984;14(2):243-251
Clinical electrophysiological studies(EPS) were done in seven patients with chronic recurrent sustained ventricular tachycardia(VT) in an attempt to delineate the reproducibility and to select the effective antiarrhythmic drugs for the prevention of the recurrence of VT. We could induce and terminate the sustained VT, and could select the effective antiarrhythmic drugs in all patient in the cardiac catheterization laboratory with EPS. With these effective antiarrhythmic drugs VT did not recur for the follow up period of 15 to 20 months. In view of the serious nature of the VT and the demonstrated benefits of EPS, we could conclude that patients with chronic recurrent sustained VT should undergo EPS.

2.A Clinical Study on the Antihypertensive Effects of Lasix(R) Retard 30.
Korean Circulation Journal 1980;10(1):65-69
The antihypertensive action of Lasix(R) retard 30 was evaluated in 20 cases of essential hypertension on an outpatient basis. The following results were obtained. 1. The patient population comprised 11 males and 9 females, aged 32 to 67 years, with mild to moderate essential hypertension. mean age was 50 years, with 75% between 40 and 59 years of age. 2. The daily effective doses ranged from 1 to 3 capsules with an average of 1.7 capsules. The total duration of medication ranged from 4 to 12 weeks with an average of 6.5 weeks. 3. In 60% of the cases, good or fair control of blood pressure was resulted. Most of the poor results were in the cases of moderate hypertension, but the results could be improved with continuous treatment or combination with other antihypertensive drugs. 4. Transient dizziness and drowsiness were complained by 2 patients, but subsided spontaneously with continuous treatment. 5. In view of these results, Lasix retard 30 appears to be effective and well tolerated agent for the treatment of mild to moderate hypertension, either used alone or combined with other antihypertensive drugs.

8.Learning Element Recognition and Academic Achievement of Nursing Student Receiving PBL with Simulation Education.
Journal of Korean Academy of Adult Nursing 2008;20(5):731-742
PURPOSE: The purpose of this study was to analyze how a nursing student recognizes PBL with simulation education and its relationship to academic achievement. METHODS: The study objects were the students in C college who learn through PBL using simulator for 15 weeks(September 2007 to December 2007). Learning element recognition was developed by Cho(2002) and three key evaluations(performance, self-evaluation, and colleague evaluation) were designed by professors. RESULTS: Learning element recognition ranged from 2.37 to 4.83 with the average at 3.94. For Learning element recognition, students who preferred discussion score 4.15. This was statistically more significant than those who do not. Students who preferred presentations show significantly higher score in colleague evaluation. For Learning element recognition and academic achievement, self-evaluation and colleague evaluation showed relationship to PBL learning element. CONCLUSION: There was definitely a relationship with PBL learning element and academic achievement after learning the PBL with simulation education.

Recently, the proportion of cardiovascular disease as a cause of death in diabetics is in ever increasing tendency. Present study is designed to evaluate the change of myocardial performance by the effect of microangiopathy of diabetics. The measurements of systolic time intervals were obtained from simultaneous high speed recordings(100mm/sec) of electrocardiography, phonocardiography, and carotid pulse tracing in diabetics(male 26, female 31). 1. As the diabetic retinopathy got severe, shortening of LVET and prologation of PEP were noted, but QS2 showed no significant change. 2. PEP/LVET ratio fo diabetics without diabetic retinopathy was significantly higher than that of normal control(p<0.01). 3. PEP/LVET ratio of diabetics with diastolic blood pressure under 95mmHg was significantly higher than that of normal control group(p<0.01), and PEP/LVET ratio of diabetics with diastolic blood pressure over 96mmHg was significantly higher than that of normal control and that of diabetics with diastolic blood pressure under 95mmHg(p<0.01). 4. PEP/LVET ratio of diabetics with proliperative retinopathy was significantly higher than that of normal control and that of diabetics with mild diabetic retinopathy(p<0.01), but this result was not conclusive because of the small case number.

Alzheimer's disease (AD) is an age-related disorder. Both the prevalence and the incidence of AD double approximately every 5 years after the age of 60. This is a particularly serious problem considering that the Korean elderly population is rapidly growing. We present three illustrative cases of AD in mild, moderate, and advanced stages, respectively. Their initial symptoms were memory impairment which was followed by language disturbance and visuospatial dysfunction. Abnormal behaviors such as delusion and aggression occurred in moderate and severe cases. The presence and severity of dementia in these cases were established by history taking, neurological examination, standardized mental status assessment, and neuropsychological test. Laboratory investigations showed no abnormalities that could account for the cognitive deficits. Brain CT or MRI findings of the patients wee not remarkable except for a diffuse atrophy demonstrated by increased ventricular volume, narrowed gyri, and widened sulci, As an addendum, risk factors, clinical symptoms, clinical diagnosis, and natural history of AD were reviewed.
