1.Studies on Plasma Renin and Aldosterone in Essential Hypertension.
Korean Circulation Journal 1974;4(2):1-24
Plasma renin activity (PRA) and aldosterone were measured to evaluate various status of clinical conditions in normal controls and patients with essential hypertension. Fourteen controls and 45 essential hypertensive patients for PRA, and 10 controls and 28 patients with essential hypertension for plasma aldosterone were studied. The results obtained are summarizing as follows. 1. Mean value of PRA of normal subjects was 2.9+/-1.4ng/ml/hr at rest, and 5.9+/-2.3ng/ml/hr by double stimulation, respectively, the latter elevated up to twice the former. 2. Mean value of PRA in the patients with essential hypertension was 3.37+/-3.0ng/ml/hr at rest, and 5.99+/-4.9ng/ml/hr by double stimulation. The latter have increased to 1.8 times the former. 3. The patients with low PRA observed in 33.3%, the normal in 42.2%, and the high in 22.5%, at rest. After double stimulation, the low group was observed in 22.2%, the normal in 60.0%, and the high in 17.8%. 4. Mean age of the patietns with low PRA was 57.2+/-2.6 years. Though it was higher than those of normal and high PRA groups(52.0+/-10.1 years), statistical significances were observed (0.05

PURPOSE: To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H&N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. MATERIALS AND METHODS: Three node-negative H&N cancer patients and five healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. RESULTS: The mean radial displacements were 2.26 (+/-1.03) mm in the control group and 3.05 (+/-1.97) in the H&N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. CONCLUSION: This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.

4.The Effects of Hospital Nurses' Self-Esteem and Communication Skill on Self-Leadership and the Quality of Nursing Service.
Journal of Korean Academy of Nursing Administration 2016;22(3):220-229
PURPOSE: The objective of this study was to investigate the influence of hospital nurses' self-leadership, communication skill, and self-esteem on the quality of nursing service. METHODS: The participants, 230 nurses working at a general hospital in Seoul, completed a cross-sectional descriptive questionnaire survey between January 17 and 28, 2014. The collected data were analyzed using the SPSS 19.0 program for descriptive statistics, t-test, one way & two way ANOVA, correlation, and multiple regression analysis. RESULTS: Nurses' self-esteem and communication skill had significant main effects on self-leadership and the quality of nursing service, but the interaction effect of the two independent variables was not significant. Variables that significantly influenced the quality of nursing service were self-leadership, communication skill, self-esteem, and career longevity. The explanatory power of these variables for the quality of nursing service was 54.4%. CONCLUSION: Findings indicate a need for education programs for nurses which are designed to promote communication skill and enhance self-esteem and self-leadership skills which will in turn enhance the quality of nursing service.

BACKGROUND: A low level of high-density lipoprotein-cholesterol (HDL-C) is well known as an important cardiovascular risk factor which is closely associated with physical activity levels. However, there is a very few studies conducted on relationship between physical activity and HDL-C status among Korean adults. METHODS: We selected total 22,294 people aged 19 to 69 years old who had not taken lipid lowering agents from the 2005 Korea National Health and Nutrition Examination Survey (NHANES) data. The population was classified into three groups using the criteria for HDL-C of Adult Treatment Panel III. The relationship between the physical activity and HDL-C was investigated and the amount of physical activity levels of the three HDL-C groups were obtained with analysis of covariance with adjustments for various factors influencing the physical activity levels. RESULTS: After adjusted for various factors influencing HDL-C, physical activity is significantly associated with HDL-C. As physical activity is increased, HDL-C is much higher (P<0.001).The physical activity levels were significantly different among the three HDL-C groups. The amount of physical activity in low HDL-C group was significantly low compared to high HDL-C group (1653.08+/-65.31 MET-min/wk vs. 1916.70+/-102.86 MET-min/wk, P<0.001). CONCLUSIONS: We confirmed that the amount of physical activity level in low HDL-C group was significantly lower compared with that of high HDL-C group in Korean adults.

An analytical observation was carried out on clinical symptoms, physical findings, etiology, precipitating factors, pulse rate, and blood pressure manifested by 115 patients admitted to the Kyung hee university Hospital under the diagnosis of congestive heart failure for a period of October 1971 to September 1974. The results were as follows: 1. The disease affected female 1.4 times more frequently than male and occured most frequently in the 6th decade (26.1%), and its incidence decreased in the 7th decade (22.6%). 2. The important causes of congestive heart failure were hypertensive heart disease (39.7%), rheumatic heart disease (26.1%), cor pulmonale (13.9%), atherosclerotic heart disease (6.1%), postpartum heart failure (6.1%) and pericardial disease (3.5%). The unknown etiology was 3.5% of all cases. 3. The most common precipitatiog factors of the 106 patients of congestive heart failure were infections (59.5%), especially in the upper respiratory tract infection (37.8%). The physical exertion, pregnancy and labor, psychic stress, angina, myocardial infarction, and discontinuation of Tapazol and digitalis were followed. 4. The most common symptoms and signs were the dyspnea (93%), and the next common were pulmonary rales (65.2%), hepatomegaly (59.1%), distention of cervical vein (55.7%), pitting edema (44.3%) and cardiac murmur (38.3%) on admission. 5. The increased pulse rate over 101/min. was about 38.3%, but less than 60/min. was found in 4.3% only. 6. The electrocardiographic findings were abnormal except one case out of 107 cases. The left ventricular hypertrophy (48.1%), atrial fibrillation (24.5%), and bundle branch block (21.7%) were frequently observed. 7. The range of systolic blood pressure measured in 43 patients who had been suffered from hypertensive heart disease were disclosed that 221-240 mmHg (23.3%), 161-180mmHg (20.9%), and 181-200mmHg (20.9%) in order.

Six patients of sick sinus syndrome were described with review of literatures, who demonstrated either persistent unexpected sinus bradycardia (5 patients) with sinus arrest in one patients or bradycardia-tachycardia syndrome (1 patient). These occurred due to disorders of sinoatrial conduction and depression of atrioventricular junctional escape pacemaker system. Singificant atrioventricular block was not present. Coronary heart disease, hypertension, valvular heart disease, and tetanus were demonstrated where etiology could be determined, but in one patient no clear etiologic diagnosis could be established. Syncope and dizziness were common sympotms and in one patients with atrial fibrillation occurred cerebral embolism.
