2.Study for Mitral B-Bump and Its Relation to Left Ventricular Dysfunction by M-Mode Echocardiography.
Korean Circulation Journal 1991;21(1):100-106
Normally the AC segment of mitral valve echogram consists of a rapid slope, from A peak to C point(complete closure). The initial portion is usually less steep than its final portion ; the latter represents abrupt mitral valve closure secondary to the rapid rise in left ventricular(LV) pressure at the onset of LV systole. The point on the mitral echogram at which closure aburptly accelerates in the B point. In order to see wither or not the echocardiographically recorded mitral valve could reflect alterations in left ventricular pressure, mitral valve echograms and left ventricular pressure were obtained on 30 patients undergoing diagnostic cardiac catheterization. The results were as follow : 1) Of 23 patients with LV ejection fraction>55%(71.2%+/-7.9%), 2 had B-bump ; of 7 patients with LV ejection fraction<55%(47.0%+/-4.9%), 5 had B-bump. The difference in frequency of B-bump between the normal LV ejection fraction and the low LV ejection fraction groups was statistically significant(p<0.001). 2) Of 6 patients with LVEDP>5mmHg (17.7mmHg+/-3.6mmHg), 5 had B-bump ; of 24 patients with LVEDP<15mmHg (8.5mmHg+/-2.6mmHg), 2 had B-bump. The difference in frequency of B-bump between the normal LVEDP and the elevated LVEDP groups was statistically significant(p<0.001). 3) Of 22 patients with LV ejection fraction>55%(71.2%+/-7.9%), as well as LVDEP<15mmHg(8.5mmHg+/-2.6mmHg), 1 had B-bump ; Of 5 patients with LV ejection fraction<55%(47.0+/-4.9%), as well as LVEDP>15mmHg(17.8mmHg+/-3.6mmHg), 4 had B-bump. The difference in frequency of B-bump between in normal LV ejection fraction, as well as normal LVEDP and the low LV ejection fraction, as well as elevated LVEDP groups was statistically significant(p<0.001). Thus, the mitral B-bump correlated primarily with LV dysfunction. When properly recorded, the presence of a B-bump is a useful sign of significantl LV dysfunction.

3.CGRP Immunoreactivities Following Artificail Ureteral Calsulosis and Ureteral Chemical Irritation in the Rat.
Korean Journal of Anatomy 1998;31(4):557-564
The aim of the present study was to investigate the CGRP-IR pattern in the ureter in stone-implanted rats and ureteral formalin irritated rats. Artificial ureteral stone rats were made according to Giamberardino's guide lines. For urethral formalin irritated rats, a small amount of diluted formalin was instilled into the ureter. The behavioral characteristics were observed and recorded with CCTV and analyzed, statistically. The rats showing characteristic visceral episode were sacrificed three days after stone implantation operation and after overnight chemical irritation followed by immunostaining of the ureter with anti-CGRP on the ureter In the artificial ureteral stone rats, CGRP IR fiber pattern showed variable changes on the upper portion of the stone implanted ureter. i.e., complete depletion, reticular pattern, and reticular pattern with more increased CGRP immunoreactivity were observed. In contrast, more-distinct CGRP IR fibers formed a reticular pattern but were not increased in density in the formalin irritated ureter. The results show the variable changing pattern of CGRP immunoreactivity in the ureter after artificial urethral calculosis, and the constant CGRP immunoreactivity in the ureter after chemical ureteral irritation.

5.A Study on the Home Health Care Needs of Postpartum Women.
Korean Journal of Women Health Nursing 2001;7(4):579-595
This study was carried out to understand the home health care needs of postpartum women during the postpartum period. The goal of this study was to obtain data needed to develope postpartum home health care programs and to improve the nursing quality for postpartum women. A convenient sample of 105 healthy women who were discharged after delivery at a maternity hospital in Ulsan, Korea were studied from January 25 to April 15, 2001. Data collection was done with a structured questionnaire (maternal concerns questionnaire) by mailing. Data was collected from 1 to 4 weeks after delivery. The Results of this study were as follows: 1. The mean score of home health care need of postpartum women was 2.51. The degree of nursing need according to the category of home health care needs was 'concerns about the infant (2.91 +/- .68)', 'maternal physical and emotional concerns (2.62 +/- .52)', 'concerns related to the husband (2.45+/-73)', 'concerns related to the family (2.16+/-.64)', 'concerns related to the community (2.03+/-.60)' in rank. Among the items, 'recognizing illness in the newborn (3.36+/-.83)', 'normal growth and development (3.33+/-.92)' were high. 2. Among items of concerns about infant (2.91+/-.68), 'recognizing illness in the newborn (3.36+/-.83)', 'normal growth and development (3.33+/-.52)' showed high nursing needs. 3. Among items of maternal physical and emotional concerns (2.62+/-.52), 'being a good mother (3.31=/-.86)', 'return of their figures to normal (3.04+/-1.05) showed high nursing needs. 4. Among items of concerns about husband (2.45+/-.73), 'husband being a good father (2.84+/-1.00) shows high nursing needs. 5. Among items of concerns related to the community (2.03+/-.60), 'getting to health care facilities (2.69+/-.90) shows high nursing needs. 6. On considering the relationship between the postpartum women s home health care needs and their general characteristics, parity (t=2.436, p=.017) and delivery type (t=2.074, p=.041) were statistically significant.

6.A Structural Model of Hospital Nurses' Turnover Intention: Focusing on Organizational Characteristics, Job Satisfaction, and Job Embeddedness.
Journal of Korean Academy of Nursing Administration 2016;22(3):292-302
PURPOSE: This study was done to build and verify a model of clinical nurses' turnover intention using organizational characteristics, job satisfaction and job embeddedness. METHODS: The study participants were 389 hospital nurses. SPSS and AMOS 22.0 program were used to analyze the data and the modeling of turnover intention. RESULTS: A total of 41% of turnover intention was explained by job satisfaction, job embeddedness and organizational characteristics. Nurses with higher job satisfaction and job embeddedness showed lower turnover intention, while organizational characteristics had an indirect effect on their turnover intention. It was found that organizational characteristics had positive effects on both job satisfaction and job embeddedness, and job embeddedness played a mediating role between organizational characteristics and turnover intention. CONCLUSION: To reduce nurses' turnover intention, hospitals' organizational characteristics should be considered. Nurse managers should strive to increase nurses' job satisfaction and job embeddedness through an understanding of the factors of organizational characteristics such as organizational fairness, nursing work environment, motivation, organizational citizenship behavior, and transformational leadership.

The study was undertaken to evaluate the heat resistance by split dose hyperthermia in various time intervaland temperature. For the experiments, 96 mice were divided into 2 groups: the first, 36 mice were used to evaluatethe skine reaction of mouse tail to single dose hyperathermia, the second, 60 mice were used to evaluate heatresistance by split dose hyperthermia in variuos time intervals. The results obtained are summarized as follows;1. The ND was 101 minutes at 43degrees centigrade(C) and 24 minutes at 45degrees C. 2. For a 1degrees C increasein temperature, a half in time was required to same degree of skin reaction. 3. Heat resistance was significantlydeveloped in split dose hyperthermia at 43degrees C and 45degrees C. 4. Development, maximum and decay of heatresistance were constant regardless of change in temperature. In summary, heat resistance in split dosehyperthermia is important in study and clinical application of heat therapy in malignant disease.

In the past two decades, the incidence of rubella infection has decreased due to a nation-wide rubella vaccination program. Therefore the rate of rubella Ig G antibody has decreased. This means an increasing vulnerability to rubella infection among the group, with negative Ig G antibodies. The study was conducted in January of 1992 to April of 1996. The subjects were 1,010 fertile women(ages 20/45 years). The study was performed at Park Women`s Clinic to investigate the status of rubella antibody in Korean fertile women. The results were as follows. 1. The positive rate of rubella Ig G and Ig M antibody were 80.5% and 1.5%, respectively. 2. The mean age of positive rubella Ig G group was 28.5+/-3.6 years. The positive rate of rubella Ig G antibody was decreased by an increase in age with a significant level at p < 0.05. 3. The positive rate of rubella Ig G antibody was 63.3% in 1992, 71.3% in 1993, 87.5% in 1994, 81.1% in 1995 and 83.8% in 1996. The increase in the positive rate of rubella Ig G antibody by year for 5 years was statistically significant at p < 0.05. 4. The positive rubella Ig M antibody was noted in 15 women. Among them, one woman was tested in 1993, 5 women in 1995 and 9 women in 1996. The incidence of rubella infection had increased by years, and was statistically significant at p < 0.05. 5. The mean titer of rubella Ig G antibody was 47.18+/-50.04 IU/ml. The titer of rubella Ig G antibody was decreased by the increased in at age(p < 0.05). We observed a low positive rate of rubella Ig G antibody as compaired with other studies that were performed before 1990. Therefore, to prevent sporadic rubella infections, rubella vaccinations should be given to unmarried women.
