  • The subjects in this study were 500 students who were selected from a population that consisted of security majors who took courses in martial arts in four different four-year-course universities. After a survey was conducted, the answer sheets from 451 students were analyzed except 49 incomplete ones. The collected data were analyzed with SPSS Ver. 12.0 program. Frequency analysis, t-test and one-way ANOVA were utilized, and LSD and regression analysis were employed to make a post-hoc comparison. All the hypotheses formulated in this study were verified at the a=.05(Chronbach's alpha) level of significance. The findings of the study were as follows: First, as for relations between demographic characteristics and self- realization, the college students investigated were statistically different according to gender in three subvariables of self-realization that included ability development, ability display and attainment of ideal. Age and academic year made a significant difference to their ability development and attainment of ideal, and they differed statistically significantly in terms of ability development according to black lebel test. Second, concerning connections between the degree of martial-arts training and self-realization, training term, one of the subvariables of the degree of martial-arts training had a positive correlation to their ability development and attainment of ideal at the 5% level of significance, and training time was positively correlated to their ability development at the 5% level of significance. Third, training term, one of the subvariables of the degree of martial- arts training, had an impact on ability development, and that exerted a firsthand influence on attainment of ideal as well.

  • National Innovative Capability (NIC) is an important decisive factor where economic growth is concerned. As such, it is very important to measure and manage NIC. The composite index approach is one of the widely used approaches to measuring NIC, but there have been insufficient reviews of its feasibility and reliability. This paper conducted an analysis of the feasibility and reliability of the report on the last three years (i.e. 2011 through 2013) of the Innovation Union Scoreboard (IUS) of the EU, which is the most representative means of measuring NIC. It turned out that its reliability meets the recommended criteria as a result of Chronbach's alpha-based test of the models of IUS-related composite index. However, neither the absolute fit index nor the incremental fit index was found to meet the recommended criteria in a construct validity analysis. It also turned out that predictive validity is very low as a result of panel linear regression analysis of sectors and items of IUS-related composite index. This paper presents a number of considerations to be made when measuring national innovative capability using the composite index approach, as well as major policy suggestions based on the results of the analysis.

  • The purpose of this study is to investigate the relationship between the number of first aid training and safety performance. The researcher's questionnaire consisted of three variables: necessity of first aid education, application to security practice, and improvement of job satisfaction. In this study, Chronbach's Alpha coefficients were calculated to measure the internal validity for the reliability of the questionnaire. In order to verify the validity of the measured variables, exploratory factor analysis was carried out using the Berimax rotation method. The mean variance extracted AVE and the conceptual reliability CR value of the measurement result variables were both above the allowable reference value of 0.5 and it was judged to be a good test in terms of intensive validity. As a result of the hypothesis test, the standardization coefficient was 1.106 for 'necessity of first aid education ⇒ applied to security practice work', and 'applied to security work practice ⇒ improvement of job satisfaction' was 1.063 and the relationship of hypothesis 1 hypothesis 2 was significant (+), Respectively. Therefore, in order to increase the job satisfaction of security related workers, it is necessary to support first aid education and to receive first aid education.

  • Purpose: The purpose of this study was to develop clinical education of Oriental Nursing. Methods: The subjects were one hundred and ninety-three students who have completed clinical practice. The questionnaires were composed of experience type and Oriental Nursing practices(25 items), level of satisfaction(20 items), difficulty level of practices(6 items), and preparation level of practice instructor(5 items). The reliability were Chronbach's $\alpha$=.84, .86, .74, and .93 respectively. Frequencies, percentage, t-test, and Pearson's Correlation was used in data analysis using SPSS PC+ 11.0. Results: Nursing students recognized that they had difficulties caused by a lack of knowledge of Oriental medicine, of learning the uniqueness of the nurse's role and lack of nurse's enthusiasm in teaching students. However, they were confident in preparing acupuncture and implementing Moxibustion, large Moxibustion, Bu-Hang therapy, aroma therapy and on administration of medicines and control of temperature of the medicines, exercise and rehabilitation. Therefore, instructors should train nursing students by developing a unique Oriental Nursing practice and reinforcement of nurses' independent and cooperative roles through the acquisition of Oriental Medical knowledge and terminology. It is necessary that they develop an educational program based on Oriental Nursing practice, perform consistently within the program and train its teaching faculty and instructors.

  • The purposes of this study were (1) to describe the effects of transformational leadership and transactional leadership on the hospital member's organizational commitment and turnover intention, (2) to provide with fundamental data in enhancing organizational effectiveness. For this purpose, the types of leadership, organizational commitment and turnover intention were evaluated among hospital members. A survey was conducted with 827 respondents working in a general hospital in Sungnam-shi. For the data analysis SPSS 10.0 was utilized. To verify the reliability and validity of variables, Chronbach's ${\alpha}$ and confirmatory factor analysis were processed. After descriptive analysis, regression analysis was conducted. In these progresses all the statistical significant levels were set at ${\alpha}$= 0.05. Results of the study can be summarized as follows. First, the types of leadership had differences in the level of organizational commitment and turnover intention of the hospital members and then transformational leadership had a more influence than did transactional leadership. Second, there were significant correlations for organizational commitment and turnover intention with overall characteristics of leadership(p<.05). Third, the factor influencing hospital member's organizational commitment and turnover intention were transformational leadership(p<.001). Total explanatory powers($R^2$) were 20.2% (organizational commitment) and 12.1%(turnover intention). Multiple regression analysis demonstrated that organizational commitment significantly high when transformational leadership was higher and it also showed turnover intention was significantly lower. In conclusion, the results of this study show that the leadership influence hospital member's organizational commitment and turnover intention and they are different the types of leadership. This results suggest that in order to be as successful leaders in hospital, the leaders should know their employee's behaviors and change their leadership styles.

  • Purpose: This study was conducted to develop a Korean version of the pediatric functional muscle test (K-PFMT) for children with motor developmental disorders, and to verify its reliability and validity. Methods: The subjects were 40 children, aged below 5 years. Each was scored on the K-PFMT by 14 physical therapists to determine inter-rater reliability and internal consistency. Additionally, 3 of the 14 therapists tested 20 children again one or two weeks later to determine test-retest reliability. The internal consistency was calculated by Cronbach's alpha. The inter-rater and test-retest reliability were calculated using the intraclass correlation coefficient (ICC). One-way ANOVA and the paired t-test were used to compare differences among the three evaluator groups and between the test and retest group. Concurrent validity was evaluated by Pearson's correlation with a total score of GMFM. Results: Chronbach's alpha was over 0.98 for each test item and 0.99 for the total items. There was no significant differences in the score of K-PFMT among the three evaluator groups except for a few items. The test-retest ICC was from 0.89 to 1.00 and from 0.82 to 1.00, respectively. There was no significant difference between the test and retest group, except for a few items. There were high significant correlations between K-PFMT and GMFM. Conclusion: This study showed that a K-PFMT with relatively high reliability and validity was successfully developed. The K-PFMT will be a useful tool for measurement of muscle strength of children with motor developmental disorder.
