  • The purpose of this study is to examine the necessity of introduction of NCS curriculum for culture and arts management at four - year college and whether NCS education is helpful for employment and acquiring certification. For this purpose, we set up the research model "Culture Arts Management NCS Education, Necessity of NCS curriculum introducing at 4-year universities, Help in employment and business performance" and surveyed. As a result, Chronbach's Alpha coefficients were calculated as 0.821, 0.807, and 0.830 and the internal consistency was secured. The validity analysis of the measured variables was also calculated above the reference value(0.5). And it was found that both intensive validity and discriminant validity were secured. As a result of the hypothesis test, the standardization coefficients were 0.608 and 0.977, and both hypotheses showed positive (+) relationship. Therefore, each research hypothesis was highly correlated.

  • Purpose: The aim of this study was to examine the test-retest and inter-rater reliability of the pediatric functional muscle testing (PFMT) when applied to children with developmental delay. Methods: Sixteen children with developmental delay (seven females, nine males) participated in this study. For the inter-rater reliability, each was scored on the PMFT by two pediatric physical therapists with more than 8 years of clinical experience on the same day. For assessment of the test-retest reliability, one therapist tested the children again within 10 days. The second measurement was performed by taking a first measurement in video. Intraclass correlation coefficient (ICC) was calculated to determine the test-retest and inter-rater reliability of the PFMT, and Chronbach's alpha was used to measure internal consistency. Results: The results of this study were as follows: 1) The test-retest ICC of the score of the infant action month and the right side of the PFMT was from 0.53 to 1.00 and from 0.63 to 0.99, respectively. 2) The inter-rater ICC of the score of the infant action month and the right side of the PFMT was from 0.66 to 1.00 and from 0.64 to 1.00, respectively. 3) Chronbach's alpha was 0.93. The internal consistency indicated excellent. Conclusion: In conclusion, this study showed that the test-retest and inter-rater reliability of the PFMT was relatively high, except for a few items. Therefore, it can be suggested that the PFMT will be a useful tool for measurement of muscle strength for children with developmental delay if it be some modifications.

  • The purpose of this study is to analyze the relation of security officers' martial arts training and job performance. To this end, we conducted surveys on security practitioners. The questionnaire consisted of three variables, "necessity of martial arts training, application to practical security work, improvement of job satisfaction". In this study for reliability analysis, Chronbach's Alpha coefficient was calculated. In order to verify the validity of the measured variables, exploratory factors were analyzed using the Berimax method. Both AVE and CR values of the measured variables were above the reference value of 0.5, indicating that the convergence validity was good. As a result of the hypothesis test, the standardization coefficient is 0.636 for "need for training in martial arts training${\Rightarrow}$practical security work", 0.986 for "practical security work${\Rightarrow}$job satisfaction improving", and the relationship between the two hypotheses is positive(+). In order to improve the job satisfaction of security-related practitioners, it seems necessary to raise the need for martial arts training.

  • The purpose of this study conducted to conduct a survey to understand the effect of security major college students' major selection motives on major satisfaction and career decisions. The questionnaire was written as "First, motivation for choice, second, major satisfaction, third, career decision". In this study, Chronbach's Alpha coefficient was calculated to analyze the reliability and importance of variables and to identify exploratory factors. And the Berimax method was performed. Both the AVE and CR values of the measured items were calculated to be above the reference value of 0.7, and thus, the convergent validity of each item was investigated as favorable. In the hypothesis test results, the standardization coefficient of 'selection motive ⇨ major satisfaction' was 0.653 and 'major satisfaction ⇨ career decision' was 0.403, so both research hypotheses were adopted. However, 'selection motive ⇨ career decision' was rejected with 0.392. In the future, universities and related professors seem to need more efforts to simultaneously increase the selection motive and major satisfaction in order to improve the career decisions of college security students.

  • The purpose of this study is to analyze the recognition of the parents of scientifically gifted children of the need for parent education. In order to attain this goal, questions were developed about their recognition for the need of a parent education program. A sample of parents (N=121) was selected. Data analysis indicated that the instruments developed in this study had proper validity and reliability measurements (Chronbach ${\alpha}=0.93$ for parent questionnaire). The results showed that parents want parent education, but they don't have the opportunities for it. Parents want information on courses, creativity development and counselling. Parents are especially anxious to obtain information on their children's courses. Finally, results revealed positive correlations between parents' needs and experiences in parent education. The results of study give some implications for developing parent education programs.

  • This study is a methodical research to develop a health behavior assessment scale for patients with rheumatoid arthritis, and to test the validity and reliability of the instrument. The research procedure was as follows; 1) The first step was to develop conceptual framework based on a comprehensive review of the literature, in-depth interviews patients with rheumatoid arthritis. This conceptual framework was organized in eight dimensions; pain management, exercise, rest, diet control, active committment, self-management, positive thinking, interpersonal maintenance. Initially 56 items were selected from 164 statement. 2) These items were reviewed by panel of eight specialists and the Index of Content validity (CVI) was calculated, and forty six items were selected which met more than 70% on the CVI. 3) 174 rheumatoid arthritis pateints were interviewed, and data was gathered from Jan. 25 to Feb. 18, 1999 for test reliabilities and validities of the scale. The item analysis was carried out and 40 items were selected. Factor analysis by varimax rotation was carried out to test construct validity. The internal consistency by chronbach's $\alpha$ was calculated. The findings were as follows; 1) Item analysis and factor analysis were carried out to test the validity of the health behavior assessment scale. The item analysis was based on the corrected item`s to total correlation coefficient (.30 or more), and information about the alpha estimate. However, this was only if this item was deleted from the scale. As a result of the item analysis, forty items were selected. Thirty items were selected by a initial factor analysis by varimax rotation, and ten items were deleted because of factor complexity. In the secondary factor analysis, eight factors were labled as 'positive thinking', 'exercise', 'rest', 'pain management', 'active committment', 'self-management', 'diet control', and 'interpersonal maintenance', each similar with the conceptual framework. 2) Chronbach's $\alpha$ coefficient to test reliability of the scale was. 903 for total the thirty items. The Scale for assessing health behavior developed in this study was identified to be a tool with a high degree of reliability and validity. Therefore this scale can be effectively utilized for assessment in the health behaviors of the patients with rheumatoid arthritis.

  • Objectives : The purpose of this study was to examine the reliability and validity of the Korean version of Asperger Syndrome Diagnostic Scale as a tool to diagnose Asperger disorder. Methods : Subjects consisted of 15 Asperger disorder, 20 PDD & PDD NOS, 20 Communication disorder children who visited the department of child psychiatric outpatient clinic. The age range of the children was between 5 years 1 month and 15 years 6 month. The K-ASDS, the Korean version of Asperger disorder inventory (K-ADI), and K-CARS were administered to mothers of all children by clinical psychologists. Results The internal consistency of the ASDS was high (Chronbach's $\alpha=0.88$) and the range internal consistencies of each subscales of K-ASDS were from .83 to 66. Correlation coefficients between K-ASDS and KADI was significant. Discriminant analysis showed that the Korean version of ASDS significantly discriminate Asperger disorder from PDD and Communication disorder, and the percentage of correct classification were $71\%$. Conclusion : The results of this study proved that the Korean version of ASDS was a reliable and valid measure for Asperger disorder.

  • The purpose of the study was to determine the convergent validity, discriminant validity and internal consistancy reliability of the social support and family support measuring tool. Two procedures were used : 1) Campbell and Fiske's multitrait-multimethod approach and item total correlation with Chronbach's $\alpha$. The result suggest that SNM, NSSQ, SNM/family, NSSQ/famliy is a valid and a reliable instrument for measuring social support. But PRQ part2 is low in convergent validity. The results further suggest that we have to more attention to a valid and reliable likert type scale for social support.

  • Objectives: This study was to determine diabetes fatalism of diabetic patients with and without diabetic foot and its association with lifestyle, diet, and self-care. Methods: The subjects were diabetic patients with (male/female 48/21) and without diabetic foot (male/female 33/26). We administered the questionnaires which were designed to determine diabetes fatalism, lifestyle, diet, and self-care. Diabetes fatalism was determined by Diabetes fatalism scale (DFS), which consisted of total 12 items in three subscales namely, emotional stress, religiou spiritual coping, and perceived self-efficacy. Results: The patients with diabetic foot had undesirable diets more frequently (1.37 and 0.91 days/week respectively) and their desirable diets (2.74 and 3.61 days/week respectively) and foot care (4.61 and 5.53 days/week respectively) were less frequent than those without diabetic foot (p < 0.05). An item analysis of the 12 DFS items revealed a Chronbach' ${\alpha}$ of 0.614 and 0.869, respectively in diabetic patients with and without diabetic foot. Perceived self-efficacy related DFS of subjects without diabetic foot was positively associated with smoking (r=0.350, p<0.01), undesirable diet (r=0.295, p<0.05), and drinking (r=0.257, p<0.05), while its negative association with exercise (r=-0.224, p<0.088) and foot care (r=-0.247, p<0.059) did not reach to statistical significance. Conclusions: This work was the first study reporting the potential usefulness of DFS, especially perceived self-efficacy related subscale as a predictor of lifestyle, diet and self-care on the Korean diabetic patients, at least those without severe diabetic foot to screen those who should be the first target for diabetes education.
