The Purpose of this study was to identify the relationship among leadership style of nurse managers, job satisfaction, organizational commitment, and turnover intention. Method: The subjects were 468 nurses and 19 head nurses who were working at the 3 general hospitals in seoul. The data were collected from July 6 to September 14, 2001 by the structured questionnaires. For data analysis, descriptive statistics, ANOVA, Pearson correlation coefficient, and stepwise multiple regression with SAS package were used. Result: 1) The score of the nurse managers' transformational leadership perceived by surbodinates' were higher than that of the nurse managers' transactional leadership. Among 5 subdimensions of the leadership styles perceived by surbodinates', the scores of 'charisma' and 'intellectual stimulation' were highest and 'management by exception' were lowest. 2) 'Charisma', 'intellectual stimulation', 'individual consideration' and 'contingent reward' were positively related to all of variables except 'turnover intention'. 'Management by exception' was negatively related to all of variables and was positively related to 'turnover intention'. 3) 'Job satisfaction' was positively related to 'organizational commitment' and 'Job satisfaction', 'organizational commitment' were negatively related to 'turnover intention'. 4) As a result of stepwise multiple regression analysis, the key determinants of 'turnover intention' were 'organizational commitment' and this explained 44.4% of the total variance of it.

The purpose of this study was to investigate the dietary habits and altered food preferences of stroke patients. One hundred and forty-six outpatients, who had experienced their first-ever stroke and were admitted to Asan Medical Center between July and December 2000, were studied. Using interviews, we assessed the altered food preferences, food consumption frequency, and other factors influencing the food preferences and food consumption frequency of the subjects. These results were analyzed with 2 t-tests, and multiple regression analysis, using the SPSS package program. Preferences for pork, red fish, coffee, bread and stews were higher in male stroke patients than in females. The frequency of consumption of beef, pork, white fish, red fish, egg, garlic, onion, coffee, instant noodles, bread, and culinary vegetables increased in the male stroke patients more than in the females. Food preferences were influenced by income, risk factors, subjective tastes and location of brain ischemic lesions. Food consumption frequency was affected by food preference, income, drugs, alcohol, marital status, sex, and dysgeusia. As a result of multiple regression analysis, the frequency of consumption of white fish, red fish, eggs, soy milk, milk, garlic, onions, coffee, noodles, bread, bean-paste stew, kimchi, culinary vegetables, and greasy foods were the most affected by each food preference. Our results suggest that food consumption frequency may vary with food preference, income, drugs, alcohol, marital status, sex, and dysgeusia, and nutrition education should be formulated to prevent stroke recurrence based on the food preferences, subjective tastes, and risk factors of individual stroke patients.

Pedestrian injury have been the most important cause of death in children 1 to 14 years of age. This study was attempted to analyze the status and factors of the pedestrian safety education for primary school children. The purpose of this study was to provide the baseline study on pedestrian safety education. The data were collected from 313 respondents of 5th grade elementary school children in Seoul during April 26 through May 6, 1993. The data were cross tabulated for percent distribution and analyzed by multiple regression using SAS for personal computer program package. Major findings are as follows: (1) 50% of the respondents had never received any safety education for Pedestrian. The primary provider of pedestrian safety education was parent. (2) Respondents' knowledge on traffic rules, traffic signals, natures of motor vehicle is high(above 88%). (3) Respondents are very negative to the attitude of playing on the street and transversing under d1e overpass(about 80%). (4) 58% of respondents had never played on the street and 49% of respondents had never run on the street. (5) Factors affecting the knowledge of traffic safety was respondents' sex and job of their mothers(p＜0.05). (6) Factors affecting the attitude of traffic safety was economic status(p＜0.01). (7) Factors affecting the practice of traffic safety was education of respondents' fathers. (8) The multiple regression analysis showed that sex was statistically significant in affecting traffic accident of pedestrians (p=0.05). In order to prevent children's traffic accidents, education for pedestrians' safety by both parents and teachers should be strengthened.

The purpose of this study was 1) to determine physical properties, and subjective evaluation of sensation of sports socks with various type of fiber content and fabric structure, and 2) to develop regression equations for predicting each sensation from physical properties of socks. Thirty healthy male students participated in the wear test with ten replications. The ANOVA, Duncans multiple test, and multiple regression, and paired-t test were used in the statistical analysis, using an SAS package. The results of this study are as follows: 1. 100% cotton socks had higher absorbency and wickability among five different socks. Comfort sensation, tactile sensation and fit sensation of socks were significantly influenced by types of fiber content. People felt that polypropylene socks were less comfortable & slightly tighter, and cotton socks were drier than the other socks. Terry socks were warmer than single jersey socks. 2. The results of the regression analysis showed that tactile sensation of socks after exercise can be predicted from the cube of moisture permeability($R^2$=0.99), and fit sensation can be predicted from drop absorbency, moisture permeability, wickability in wale and weight($R^2$=-0.98).

Purpose: The purpose of this study was to investigate the factors affecting oral health impact profile. Methods: Subjects included elderly in the metropolitan areas of the cities of Daegu and Gyeong-buk. Statistical analysis was done using the Statistical Package for Social Sciences version 19.0 for Windows. We determined frequencies and percentage, calculating means, and standard deviations, and determining statistical significance using T-tests, analysis of variance, multiple regression analysis. Results: The results of multiple regression analysis between the oral health impact profile and the related factors indicated that Occupation, Economic status are the major component oral health impact profile in general characteristics and the Impediment of oral health promotion behavior is the major component that contribute the oral health impact profile in oral health belief. Conclusion: The comprehensive and reliable research which measures oral health impact profile of elderly is necessary.

Purpose: This study aimed at exploring the impacts of organizational conflict and job satisfaction on the turnover intention among dental technicians. Methods: This study utilized a descriptive research design. A structured questionnaire was administered to 159 dental technicians. Of the collected questionnaires, data from 127 valid questionnaires were analyzed using t-tests, analysis of variance, Pearson's correlation coefficient, and hierarchical multiple regression using the IBM SPSS 20.0 statistical package. Results: A positive correlation was identified between organizational conflict and turnover intention (r=0.46, p<0.001); however, a negative correlation was shown between job satisfaction and turnover intention (r=-0.50, p<0.001). A hierarchical multiple-regression model was employed to analyze working hours, unfair treatment from dentists and dental hygienists, organizational conflict, and job satisfaction, which contributed to providing an explanation to 39% of the turnover intention of dental technicians (F=14.16, p<0.001). Furthermore, organizational conflict (β=0.32, p<0.001), job satisfaction (β=-0.31, p=0.003), and working hours (β=0.21, p=0.010) were all shown to affect turnover intention. Conclusion: The impact of the negative consequences of organizational conflict and working hours on the turnover intention should be considered within core strategies for increasing the turnover periods for dental technicians.
