Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.

Purpose: Recently as couples have only one or two children, they concern about their children's optimal health. Furthermore, as the basic principles of Korean traditional prenatal education (Taegyo) are supported by scientific evidence, and as increasing numbers of pregnant women are recognizing Taegyo refresh, the practice of Taegyo is growing. The purpose of this study was to identify the factors associated with the practice of Taegyo among pregnant Korean women. Methods: This was a cross-sectional, survey study of 228 pregnant women recruited at a health center in South Korea using a convenience sampling method. The instruments included the perception of Taegyo scale, the spouse's support scale, the self-confidence for infant care scale, and the practice of Taegyo scale. The data were analyzed using descriptive statistics and multiple regression analyses. Results: The results of the stepwise multiple regression analysis indicated that the following factors accounted for 26.5% of the variance in the practice of Taegyo: the perception of Taegyo, family income. Conclusion: Consequently, this result showed that the pregnant women were influenced by family income, spouses' support as requisite factors, and also they developed the level of self-confidence for infant care and the perception of Taegyo as self-care agency for the practice of Taegyo. The present study findings will add to the accumulated knowledge of health care professionals about the cultural factors involved in the practice of Taegyo and the traditional cultural beliefs and culture-specific health promoting behaviors of ethnic minority pregnant women to provide culturally competent care for them.

When the fuzzy controller apply to a real plant, We have not excepted result of a satisfactory control by modeling error and lacking information about an plant. In this case, we have to adjust the scale factors for improvement of the control performance and this method need a lot of time and cost for perform a trial and error. In this paper, we proposed the fuzzy controller with the automatic adjustment of scaling factors. It was improve upon the control performance using a adequate scale factor by fuzzy logic and normalizer. As the results of simulation through the second order plant, we confirmed that the proposed the fuzzy controller within the function of automatic scale get a good response compare with the fuzzy controller within the fixed scale factor.

The teacher's role scale for improving young children's creativity is designed for both teacher self-rating and observer rating. Content validity was determined by 5 experts who defined the domains of specific content. Construct validity was obtained by the self-ratings of 404 teachers of 3- to 5-year-old children. Five factors using 38 items of the original 59 were found to be related to the teacher's role in improving young children's creativity. The factors were Indulgence and Perseverance, Flexibility, Originality, Elaboration, and Fluency. Convergent validity was confirmed by positive correlations of the Teacher's Role Scale with the Teacher's Creativity Test of the Korean Institute for Research in the Behavioral Sciences. For internal consistency, Cronbach ${\alpha}$ of the 5 factors ranged from .74 to .88. Test-retest reliability coefficientents ranged from .653 to .838. These results confirm the Scale as a valid and reliable measure of the teacher's role in improving the creativity of young children.

Purpose: The purpose of this study was to develop a scale to evaluate empowerment in woman with breast cancer and to examine the validity and reliability of the scale. Methods: The development process for the initial items included a literature review, interviews, and construction of a conceptual framework. The identified items were evaluated for content validity by experts, resulting in 3 factors and 48 preliminary items. Participants were 319 women with breast cancer recruited to test reliability and validity of the preliminary scale. Data were analyzed using item analysis, confirmatory factor analysis, criterion related validity, internal consistency and test-retest reliability. Results: The final scale consisted of 30 items and 3 factors. Factors, including 'intrapersonal factor' (14 items), 'interactional factor' (8 items), and 'behavioral factor' (8 items), were drawn up after confirmatory factor analysis. Goodness of fit of the final research model was very appropriate as shown by ${\chi}^2/df=1.86$, TLI=.90, CFI=.92, SRMR=.06, and RMSEA=.05. Criterion validity was evaluated by total correlation with the Cancer Empowerment Questionnaire .78. Cronbach's alpha for total items was .93 and test-retest reliability was .69. Conclusion: Findings from this study indicate that the scale can be used in the development of nursing interventions to promote the empowerment of women having breast cancer.

Purpose: The purpose of this study was to develop the Nurse Presence Scale and to test the reliability and validity of the instrument. Method: The subjects verifying the scale's reliability and validity were adult patients being treated in three artificial kidney unit in Pusan and Taegu from August 1 to October 15, 2000. The data was analyzed by the SPSS/WIN 8.0 program. Result: A factor analysis and was conducted items that had a factor loading more than .40, and an eigen value more than 1.0 were seleclted. The factor analysis classified a total of seven factors statistically, but the seventh factor was excluded because community was less than 4%. Therefore, there were six factors, and its communality was 62%. The explanation of domain and factors based on the conceptual framework and item content are as follows: The first factor was 'interaction' in emotional areas, the second domain was 'empathy' in cognitive areas, the third was 'attention' in emotional areas, the fourth was 'openness' in emotional areas, the fifth was 'sensitivity' in behavioral areas, and the sixth was 'physical assist' in behavioral areas. Cronbach's α coefficient to test reliability of the scale was .9766 for a total 49 items. Conclusion: The Scale for Nurse Presence developed in the study was identified as a tool with a high degree of reliability and validity. Therefore, this scale can be effectively utilized for the evaluation of nurse presence in clinical settings.

This study was conducted in order to develop a Children's Playfulness Rating Scale(CPRS) and to analyze it in terms of item discrimination, validity, and reliability. The participants in this study consisted of 861 parents whose children were aged from three to six years old. The item discrimination, determined by comparing the highest and lowest group using ${\chi}^2$, Cramer's V, was found to be satisfactory. The reliability of factors, as measured by Cronbach's ${\alpha}$, ranged from .85 to .95. The results of factor analysis identified 4 factors and 35 items were then selected from the 45 items in the original scale. The four factors identified were as follows; (1) leading participation (2) cognitive flexibility (3) expression of joy (4) voluntary full immersion. Concurrent validity was also established by using correlations between the CPRS and CPS(Children's Playfulness Scale). In conclusion, these results demonstrated that the Children's Playfulness Rating Scale is both reliable and valid.
