  • This study questionnaires 166 inpatients and outpatients with stroke in 8 hospitals, including Wonkwang University Gwangju Korean Hospital from July 2 to 31, 2001 in order to find out the influence of general nature, smoking, drinking, obesity, and perception of saltness of patients with stork on the outbreak of stroke and to examine important factors by dividing into hemorrhagic and ischemic stroke. Finally, collected data is analyzed statistically, using SPSS 7.5 statistics package. This study reaches a conclusion as follows. 1. For general nature, 86(51.8%) patients have hemorrhagic stroke and 80(48.2%), ischemic stroke in the rate of 1.59:1(male:female), suggesting that male's outbreak is more than female's. Outbreak age is ranged from 20 years to 90 years in order of 60's, 50's, and 40's. 50's-60's accounts for more than half percentage. 2. For smoking, 73(71.6%) of male patients has smoking experience and their 562% has ischemic stroke. Their cross-analysis for hemorrhagic and ischemic stroke shows significant difference with $x^2=3.90$(p<0.05). 48.6% of patients with smoking experience is ranged from 1 to 10 a day in smoking quantity. 3. For drinking, 90(88.2%) of male patients has drinking experience and their 53.3% has hemorrhagicstroke. Their cross-analysis for hemorrhagic and ischemic stroke shows no significant difference with x2=3.40(p<0.1). 59.3% of patients with drinking experience is classified as a overdrinking group. 4. For obesity, low weight is 8(4.8%): normal, 111(66.9%): excessive, 40(24.1%), and obesity, 7(4.2%). In patients with hemorrhagic stroke, excessive weight and obesity are somewhat high(33.7%). The cross-analysis for male's hemorrhagic and ischemic stork by dividing BMI into more and less than 25 shows no significant difference with x=3.52(p<0.1). 5. For perception of saltness, 21(12.7%) patients eat flat: 76(45.8%) normally, and 69(41.5%), saltily. Many patients with ischemic stroke are classified as a group who eat saltily. The cross-analysis for male's hemorrhagic and ischemic stroke shows signifiant difference with x2=10.99(p<0.05). As this study has small sample and selects inpatient and outpatient in certain local hospital, it is difficult to generalize. But the cross-analysis of male's hemorrhagic and ischemic stroke shows signifiant difference in smoking and perception of saltness. Drinking and obesity are more important factors in hemorrhagic stroke and smoking and perception of saltness in ischemic stroke.

  • In this research, various characteristics of South Korea's design flood have been examined by deriving appropriate design flood, using data obtained from careful observation of actual floods occurring in selected main watersheds of the nation. 19 watersheds were selected for research in Korea. The various characteristics of annual rainfall were analyzed by using a moving average method. The frequency analysis was decided to be performed on the annual maximum flood of succeeding one year as a reference year. For the 19 watersheds, tests of basic statistics, independent, homogeneity, and outlier were calculated per period of annual maximum flood series. By performing a test using the LH-moment ratio diagram and the Kolmogorov-Smirnov (K-S) test, among applied distributions of Gumbel (GUM), Generalized Extreme Value (GEV), Generalized Logistic (GLO) and Generalized Pareto (GPA) distribution was found to be adequate compared with other probability distributions. Parameters of GEV distribution were estimated by L, L1, L2, L3 and L4-moment method based on the change in the order of probability weighted moments. Design floods per watershed and the periods of annual maximum flood series were derived by GEV distribution. According to the result of the analysis performed by using variation rate used in this research, it has been concluded that the time for changing the design conditions to ensure the proper hydraulic structure that considers recent climate changes of the nation brought about by global warming should be around the year 2002.

  • This study was a descriptive research that attempted to provide the basis for improving cultural competence by identifying the effect of multicultural awareness and cultural empathy on the cultural competence of nursing students. The subjects were nursing students from grades 1 to 4 who were enrolled in two nursing colleges in Gwangju and Chonnam. The data were collected from September to December 2018. The 201 data collected were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with SPSS 25.0 for windows. Multicultural awareness(r=.451, p<.01) and cultural empathy(r=.582, p<.01) had high positive correlations with cultural competence. The factors that affected the cultural competence were cultural empathy(β=.422, p<.001) and multicultural awareness(β=.222, p<.001) order. The explanatory power of these factors was 40.5%. These findings suggest that in order to promote the cultural competence of nursing students, strategies to promote multicultural awareness and cultural empathy should be developed, and these strategies should focus more on cultural empathy than on multicultural awareness.

  • Current leakage of industrial technologies with revealing state secret against nation is gradually increasing and scope of the spill is diversified from technology-oriented leakage to new economic security sector like information and communication, electrical and electronic, defense industry, illegal export of strategic material, economic order disturbance by foreign country, infringement of intellectual property, etc. So the spill damage can affect not only leaked company but also national interests and entire domestic industry. According to statistics from National Industrial Security Center of National Intelligence Service, a major cause of technology leakage is not only by external things about hacking and malignant code, but internal leakage of former and current employees account for about 80%. And technology leakage due to temptation of money and personal interests followed by technology leakage of subcontractor is steadily increased. Most studies in the field of security have tended to focus on measuring security capability of company in order to prevent leakage core assets or developing measurement Indicators for management rather than security activities of the company members that is most important. Therefore, this study analyzes the effect of most underlying security education in security activities on security capabilities of enterprise. As a result, it indicates that security education have a positive(+) correlation with security capabilities.

We surveyed 668 house, 3,425 residents in Dolka area, Nepal from January 25th to February 1st, 1995. 1. In personal characteristics, the ratio of men and women was similar, the person who were below 19 years old were 28.1% and the single were 52.4%. The illeterate person were 50.3% and the lower group in economic status which had been estimated by interviewers were 46.9%. 2. In sanitational characteristics, the person who used stream water or rainwater to drink were 42.2% and the person who always boiled water to drink were only 8.3%. The person who had not toilet in their house were 67.3% and the lower group in sanitational status which had been estimated by interviewers were 61.8%. 3. The prevalence rate of illness during the last one month were 8.6% and the chronic were 26.1% and the acute were 72.5%. The distribution of sickness symptom were headache, fever and joint pain in order and the person who took no medical treatment among the sick were 37.0%. The patterns of medical utilization were public health center, hospital and pharmacy in order. 4. Illness prevalence was significantly related to sex, age, merital status and educational experience. The residents who were women, 40 years old or more, married and had not educational experience were apt to take illness. 5. Medical utilization was significantly related to educational experience, job, distance from home to medical facilities and economic status. The person who had educational experience, were officer workers or merchants, lived near by medical facilities and had higher economic status took medical treatment very well.
