Purpose: This study was undertaken to identify stroke risk with risk factors and knowledge of stork in women with prehypertension. Methods: A total of 46 pre-hypertensive women in urban area aged 44.8 (SD 11.4) yr old in average were selected by a convenient sampling. Demographic data, risk factors, and knowledge of stroke were assessed through face to face interview. Stroke risk scores were calculated based on points given to age, systolic blood pressure, smoking, DM, and heart disease in Framingham stroke risk score. Data were analyzed by SPSS WIN 12.0 using descriptive statistics, two sample t-test, and Pearson's correlation coefficient. Results: The mean systolic blood pressure of participants was 133.11 mmHg, and HDL cholesterol was lower than the recommended level, although rest of physiologic risk factors were within normal. Of the participants, 82% did not do regular physical activity and 75% did not control fat intake persistently. Mean stroke risk points and knowledge scores were 4.48 and 29.15, respectively, which were significantly different between women with and without persistent controlling fat intake. Conclusion: Results indicate stroke prevention intervention for prehypertensive women should address comprehensively modifying lifestyle as well as physiologic factors, and information focusing on stroke risk factors and warning symptoms.

The purpose of this study was to determine the predictors of health promoting lifestyles(Health Promoting Lifestyle Profile HPLP) of Koreans in the Philippines. The sample consisted of 100 Koreans who have lived in Manila, Philippines. Data were collected for two months from Feb, 1 to March 30, 1998. Analysis of the data was done by use of percentage, t-test, ANOVA, Pearson's Correlation Coefficients, and Stepwise Multiple Regression. The results of this study were summarized as follows : 1. The range of total HPLP score was from 73 to 175 and the mean score of that was 117.23. In comparison of mean scores depending on each item of six dimensions, self-actualization dimension tended to show the hightest score(2.98) and responsibility for health dimension, the lowest score(1.83). 2. The HPLP score showed a positive correlation with age(r=.19), social support (r=.39), self-efficacy(r=.52) and perceived health status(r=.27), but a inverse correlation with perceived health care service utilization barriers(r=-.20). 3. By using stepwise multiple regression analysis it was determined that the main influencing factors on the HPLP score were self-efficacy(27.2%), social support(5.3%), age(5.3%) and perceived health status(2.9%). These variables made it possible to explain 40.7% of variance in HPLP score.

Objectives: This study was conducted to examine the immunization, knowledge, and preventive health behaviors for hepatitis A in college students. Methods: Structured questionnaire survey data were collected from a convenient sample of 266 students at two universities in urban areas. Data were analyzed with Pearson correlation coefficient, t-test, ANOVA, and multiple logistic regression analysis. Results: Only 10.5 percent of the students reported having had hepatitis A vaccination. The levels of knowledge and compliance of preventive health behavior were moderate with the mean scores of 15.56(${\pm}2.12$), and 26.78(${\pm}3.41$), respectively. A significant correlation was found between knowledge and preventive health behaviors. The compliance to preventive health behaviors differed by education on hepatitis A in the past. Conclusions: Vaccination rate of hepatitis A found to be low and the knowledge and health behaviors for hepatitis A prevention among university students are limited. Provision of vaccination, education and strategies to enhance preventive health behaviors are warranted to prevent hepatitis A.

Purposes: The purposes of this study were ① to identify the rate of suicide attempts, and ② to investigate relevant variables(family dynamic environment, personality factors) and risk factors for attempting suicide among Korean adolescents. Method: Data were collected through a questionnaire survey. Internal consistencies for this questionnaire ranged from 0.63 to 0.88. Nine hundred and twenty two adolescents were surveyed (delinquent : 367, student : 555), using a proportional stratified random sampling method. Statistical methods employed were chi-square, t-test, and logistic regression analysis. Results: ① The rate of suicide attempts was 10.8％ for the total sample, and the delinquents(19.6％) had a higher rate of suicide attempts than the students(5.1％). ② Adolescents attempting suicide had a greater dysfunctional family dynamic environment and more maladaptive personality than those who did not attempt suicide. ③ Risk factors for suicide attempts among Korean adolescents were way of coping, psychosomatic symptoms, and parental child-rearing attitudes, in that order. Conclusions: Suicide and suicidal behaviors are multifaceted events. For suicide prevention, there is a need to make an independent assessment of the variables such as familial problems, personality and dynamic environment of the families of the adolescents.

Purpose: The purpose of this study was to investigate the relationship among stress, depression, coping styles and satisfaction of clinical practice in nursing students. Method: Two hundred fifty-eight nursing college students in 1 city were selected by convenient sample. A questionnaire measured the level of stress, depression, coping styles and satisfaction of clinical practice. The data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficient. Result: The mean score of stress was 2.82 (${\pm}.39$), depression was 19.23 (${\pm}7.70$), coping styles was 2.42 (${\pm}.42$), and satisfaction of clinical practice was 2.81 (${\pm}.41$). There were significant differences on four variables according to the satisfaction of a nursing major. Stress had a significant positive correlation with depression, and a negative correlation with problem focused coping and satisfaction of clinical practice. Depression had a significant negative correlation with satisfaction of clinical practice. Emotional focused coping had a significant positive correlation with depression, and problem focused coping had a significant negative correlation with depression. Conclusion: From the studies reviewed, one can expect a positive effect on decreasing stress and depression among nursing students when the nursing educators use counseling and instruction for clinical practice.

Purpose: The purpose of this study was to identify registered nurses learning needs about physical assessment. Specifically, what are the perceived competency, frequency of skill use and the unmet training needs. Methods: The study was an exploratory survey study. The sample was 104 registered nurses. Data were collected through three instruments: The Perceived Competency in Physical Assessment Scale, the Frequency of Physical Assessment Scale, and the Training Needs of Physical Assessment Scale which incorporated 30 core Physical Assessment skills. Descriptive statistics, t-test, and Pearson's correlation coefficient were used to analyze the data. Results: Auscultation of heart and lung sounds and inspection of the spine were rated by the subjects as physical assessment skills they feel least competent and also were less frequently performed. The most competent area for physical assessment was neurological system. The respiratory and abdominal system was identified as two systems that more education would be needed. Nurses with less than one year of working experience reported needing more training. Nurses with more than five years of clinical work experience performed physical assessment more frequently than nurses with less than five year of work experience. The perceived competency was positively related to the frequency of physical assessment. Conclusion: Continuing education is necessary to further train registered nurses regarding physical assessment skills and the program needs to be focused on the area which nurses are less competent for and have high training need.

In this study, a method to predict the consolidation behavior of soft clays and marine clays was developed by combining the equation of Terzaghi's 1-dimensional consolidation and CPTu dissipation. The special attention was given to the consolidation anisotropy due to the difference between 1-D consolidation and radial consolidation of CPTu dissipation. The analysis combining two equations enables direct application of CPTu results. And above all it doesn't require to sample undisturbed specimens and determine consolidation coefficient which is both costly and time consuming and often contains measuring error. It is also advantageous that CPTu test can be carried out any position and any depth. Clays typically have a greater horizontal permeability, $k_h$, than vertical permeability, $k_v$, and the coefficient of consolidation in the horizontal direction is generally higher than the vertical direction. Various data of horizontal and vertical consolidation coefficient ratio were collected and analyzed to develop and verify the method.

Purpose: This study aimed to assess and compare the marginal fit of ceramic-based hybrid resin restoration (HYB) and zirconia restoration (ZIR) for dental computer-aided design/computer-aided manufacturing systems. Methods: A stainless steel master model was produced. The impression was first made with silicone, and then stone working models were produced. A total of twenty restorations were fabricated with two different materials: ZIR and HYB. The silicone film thickness of the marginal gap was measured using a digital microscope; digital photos were taken at a magnification of ×160, and then analyzed using a measurement software. The values of the result were evaluated with the independent-sample t-test (α=0.05). All statistical analyses were performed with a statistical software. Results: The mean values for the marginal gap was 37.14±2.96 ㎛ for HYB, compared with 40.37±5.26 ㎛ for ZIR. No significant difference was found between ZIR and HYB (p=0.107). Conclusion: As a result, the marginal fit of the restoration fabricated using the hybrid resin was better than that of the restoration fabricated using zirconia. Also, the marginal fit of all groups was below the clinical acceptable range of 120 ㎛. Thus, HYB for dental CAD/CAM system in this study is expected to be suitable for clinical use in dentistry.
