1.Predicting Exercise Behavior in Middle-aged Women: Extended Theory of Planned Behavior.
Journal of Korean Academy of Adult Nursing 2001;13(4):610-619
PURPOSE: The purpose of this study was to verify the effectiveness of the model based on the TPB, behavior-related theories, and exercise-related empirical studies in predicting exercise intention and behavior. METHODS: The subjects who participated in this study were 152 middle-aged women. The data were analyzed by use of SAS PC program and LISREL 8.12a program. RESULTS: 1) The overall fit of the hypothetical model to the data was acceptable(x2 24.01(p=0.0043), x2/df 2.67, RMSEA 0.11, standardized RMR 0.04, GFI 0.97, AGFI 0.84, NFI 0.95, NNFI 0.85). 2) Affect, subjective norm, perceived behavioral control and habit were significant determinants of the exercise intention. Attitude and facilitating conditions were not significant determinants. These six variables explained 43% of the total variance of the exercise intention. 3) Perceived behavioral control and habit were significant determinants of the exercise behavior. Intention and facilitating conditions were not significant determinants. These four variables explained 95% of the total variance of the exercise behavior. CONCLUSION: This study shows the model's applicabiltiy in explaining exercise behavior of middle-aged women, and suggests that we should focus on perceived behavioral control and habit rather than intention to improve exercise behavior of middle-aged women.

2.The effects of health education on health promoting lifestyle of college students.
Journal of Korean Academy of Adult Nursing 1997;9(1):70-85
This study has been undertaken in order to 1) test the effect of health education on the performance of health promoting lifestyle, self efficacy, control and perceived health status in college students, 2) assess whether pretreatment level of self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, 3) assess whether pre-to post-treatment changes in self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, and 4) examine the correlation between changes in subscales of health promoting lifestyle. One-group pretest-posttest design was used. Fifty eight college students at T college in T city were studied. They attended a health education, which is composed of 13 sessions(one session per week, 130 minutes per one session). This study was conducted from August 26 to December 2. The instrument used for this study included a survey of general characteristics, self-efficacy, control, perceived health status and health promoting behavior. Analysis of data was done by use of mean, percentage, paired t-test, pearson correlation coefficient and stepwise regression. The results of this study are summarized as follows : 1) The average item score for the health promoting lifestyle was low at 2.301. In the sub-categories, the highest degree of performance was interpersonal support(2.87), following self actualization, nutrition, stress management, exercise, and the lowest degree was health responsibility(1.67). Female students had lowest degree in exercise subscale(1.48). A significant correlation between self-efficacy and control, self-efficacy and perceived health status, self-efficacy and health promoting lifestyle, control and health promoting lifestyle. Self-efficacy was the highest factor predicting health promoting lifestyle of college students(38.31%). 2) No significant difference among total health promoting lifestyle and subcategories of health promoting lifestyle. Self-efficacy was increased after health education than that of before education(T=2.33, P=.023). Control was decreased after education than that of before education(T=-2.03, P=.046). 3) Pretreatment self-efficacy, control, and health status did not predict post-treatment health promoting lifestyle. 4) Pre-to post-treatment changes in self-efficacy predicted post-treatment stress management subscore. 5) Pre-to post-treatment changes in control predicted post-treatment self actualization and exercise subscale. A significant correlation between changes in self-actualization and changes in exercise, changes in self-actualization and changes in nutrition, changes in health responsibility and changes in exercise, changes in exercise and changes in interpersonal support, changes in exercise and changes in stress management, changes in nutrition and changes in interpersonal support, and changes in interpersonal support and changes in stress management.

PURPOSE: To examine the expression of Connective Tissue Growth Factor (CTGF) in osteosarcoma and to evaluate its role in osteosarcoma invasion and proliferation. MATERIALS AND METHODS: The mRNA expression of CTGF from 23 patient-derived osteosarcoma cell lines was examined, and the role of CTGF in cell invasion and proliferation was examined using siRNA transfection. RESULTS: The over-expression of CTGF mRNA was observed in 17 cell lines (74%). CTGF-specific siRNA transfection into SaOS-2 and MG63 cell lines resulted in efficient knockdown of CTGF expression on Western blot analysis. siRNA transfected cells showed decreased migration on Matrigel invasion assay and decreased cell proliferation on WST-1 assay. CONCLUSION: These results indicated that the CTGF expression may play an important role in osteosarcoma progression, and may be a therapeutic target of osteosarcoma.

Hydrocephalus is a common malformation of the central nervous system and its cause may be either congenital or acquired. The imbalance between CSF formation and absorption, obstruction of CSF pathways, impaired venous absorption, and over secretion of CSF results in excessive accumulation of the fluid in the ventricles, leading to hydrocephalus. Although ventriculo-peritoneal shunt is regarded as the main and definitive therapy for rapidly progressive hydrocephalus, shunts in newborns have a high failure rate and thus there have been a search for alternative non-invasive techniques. Acetazolamide is a carbonic anhy- drase inhibitor, which acts by reducing production of CSF in the choroid plexus. Admini- stration of acetazolamide will decrease the rate of CSF production, preventing progressive ventricular enlargement. We experienced three cases of neonatal hydrocephalus successfully treated by long-term administration of acetazolamide. Brief review and related literatures were also presented.

7.Predictors of Allied Health Science Students' Exercise Behavior: An Application of Pender's Health Promotion Model.
Journal of Korean Academy of Adult Nursing 2005;17(1):34-43
PURPOSE: This study was performed to examine predictors of allied health science students' exercise behavior using Pender's Health Promotion Model. METHOD: The subjects were 203 university students majoring in nursing, emergency medical service, and exercise prescription. The hypothetical model was based on the HPM(Pender, 1996). Exogenous variables of the model were exercise habit and role belief. Endogenous variables were exercise-related affect, exercise self-efficacy, exercise barrier, exercise intention, and exercise behavior. The data were analyzed by SAS PC program and LISREL 8.12 program. RESULT: The degree of exercise behavior was low(mean 1.86, range 1~4). The overall fit of the model to the data was acceptable. Exercise habit, exercise self-efficacy and exercise-related affect were significant predictors of exercise intention and exercise behavior. CONCLUSION: This study shows the necessity of the program to increase the level of exercise participation of university students majoring in allied health science. The model constructed in this study is applicable to explain exercise behavior of university students majoring in allied health science, and suggests that we should focus on exercise habit, exercise self- efficacy and exercise-related affect to increase the level of exercise behavior of this group.

The present study was aimed at investigating the effect of cyclosporine A (CsA) on the renal renin-angiotensin systems. In rats chronically treated with CsA, the intrarenal expression of various genes of the renin-angiotensin system was assessed by Northern blot analysis. Along with the increases in plasma and renal renin activities, chronic CsA-treatment differentially affected the renal expression of renin-angiotensin system. The treatment with CsA for one week did not significantly alter the expression of either type 1 angiotensin II receptor (AT1A) or angiotensinogen gene, but increased the renin mRNA level. The three-week-treatment caused increases in the expression not only of renin but also of AT1A and angiotensinogen genes. Supplementation with L-arginine kept the expression of renin mRNA normal in the one-week-treated, but failed to prevent the alterations of the gene expression in the three-week-treated. Feedback control among components of the renin-angiotensin system also influences angiotesinogen. In the liver, the expression of angiotensinogen mRNA was decreased by the CsA-treatment for either one- or three-weeks. In conclusion, chronic CsA-treatment is associated with a differential expression of various genes for the renin-angiotensin system. L-Arginine may be effective in maintaining the normality of renin-angiotensin system only during early period after beginning the use of CsA.
