The purposes of this study were to examine school foodservice employees' awareness on dietitians' service leadership and to analyze the effects of the service leadership on employee attitudes (leader reliability, value correspondence, and leader satisfaction). Questionnaires were distributed to 208 school foodservice employees from November 2007 to January 2008. The results were as follows. First, in terms of the employees' perception on the dietitians' service leadership, service belief gained the highest score, followed by insight, attitude, and ability: the average score was 3.8 point. Second, the leader reliability and leader satisfaction scores perceived by the employees were over 3.8 point on average but the awareness on the value correspondence was 3.43 point. Third, among the service leadership factors, service belief (p<0.001) and insight (p<0.001) had positive effects on leader reliability. Also, service belief (p<0.01), service ability (p<0.001), and insight (p<0.01) had positive effects on value correspondence. Finally, service belief (p<0.001), service ability (p<0.05), and insight (p<0.001) had positive effects on leader satisfaction. Fourth, a hypothesis test using path analysis revealed that dietitians' service leadership produced positive effects on school foodservice employees' attitudes (leader reliability, value correspondence, and leader satisfaction). In conclusion, the service leadership of dietitians directly contributed to leader satisfaction, value correspondence, and leader reliability in school foodservice employees.

Purpose: This study was conducted to test the reliability and validity of Family Burden Questionnaire. Method: The subjects were 156 caregivers of children with acute or chronic disease. To test the reliability, internal consistency using Cronbach's α coefficient was analyzed, and factor analysis, known-group technique, and concurrent validity were utilized for validity test. Result: Cronbach's α coefficient of the tool was .89. Six factors were identified and explained 58.7% of the total variance. Through analysis using known-group technique, the difference of family burden between acute and chronic disease groups was statistically significant(t= -4.09, p<.001). Correlations with mood state, other family burden score by Family Burden Interview Schedule, quality of life, and health symptoms were also relatively high and statistically significant. Conclusion: Family Burden Questionnaire showed a relatively high validity and reliability to measure the burden of caregivers caring patients with various chronic conditions in Korea. For the further study, it may be reconsidered to identify the factor structure of the Family Burden Questionnaire with the various subjects from different age groups.

Purpose: This study aimed to test the validity and reliability of the Korean version of the Families' Importance in Nursing Care-Nurses' Attitudes (FINC-NA) instrument developed by Saveman et al. Methods: The 222 pediatric nurses' data were collected from 13 hospitals in South Korea and were analyzed using descriptive statistics, exploratory factor analysis, the Pearson correlation coefficient, and the Cronbach's ${\alpha}$ in SPSS software. The AMOS program was used to conduct confirmatory factor analysis of construct validity. Results: Of the 26 initial items, 24 were ultimately selected after evaluating content validity, construct validity, and reliability. The following 6 factors were included in the Korean version of the Families' Importance in Nursing Care-Pediatric Nurses' Attitudes (KFINC-PNA): family as a 'conversational partner', 'participant in care', 'supporter for the nurse', 'burden', 'recipient of empowerment', and 'its own resource'. Conclusion: The KFINC-PNA was partially modified to explain differences in language and culture, but its validity and reliability were verified. Pediatric nurses' attitudes can be assessed using the KFINC-PNA, and adjustments to the care of hospitalized children and their families can be made based on these items. We recommend developing and verifying intervention methods that will improve family-centered care for hospitalized children and their families.

Purpose: The purpose of this study was to investigate the validity and reliability of the Korean Version of the Grit (Grit-K) scale for nursing students in Korea. Methods: The participants in the study were 277 nursing students. Their grit was verified by using self-reports and the results of a questionnaire. Grit was translated into Korean and its content validity was verified by five experts. The validity of the instrument was verified through item analysis, exploratory factor analysis, and confirmatory factor analysis. Reliability verification was analyzed by using internal consistency reliability. Results: Two factors were identified through exploratory factor analysis and six items of the original instrument were found to be valid. In the confirmatory factor analysis, the validity of the instrument was verified as the model. The internal consistency reliability was also acceptable and Grit was found to be an applicable instrument. Conclusion: This study shows that the Korean Version of the Grit Questionnaire is a valid and reliable instrument to assess nursing students in Korea.

Using vertical links in eccentric braced frames is one of the best passive structural control approaches due to its effectiveness and practicality advantages. However, in spite of the subject importance there are limited studies which evaluate the seismic reliability and response reduction factor (R-factor) in this system. Therefore, the present study has been conducted to improve the current understanding about failure mechanism in the structural systems equipped with vertical links. For this purpose, following definition of demand and capacity response reduction factors, these parameters are computed for three different buildings (4, 8 and 12 stories) equipped with this system. In this regards, pushover and incremental dynamic analysis have been employed, and seismic reliability as well as multi-level response reduction factor according to the seismic demand and capacity of the frames have been derived. Based on the results, this system demonstrates high ductility and seismic energy dissipation capacity, and using the response reduction factor as high as 8 also provides acceptable reliability for the frame in the moderate and high earthquake intensities. This system can be used in original buildings as lateral load resisting system in addition to seismic rehabilitation of the existing buildings.

Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of the Contraceptive Self-efficacy (K-CSE) scale. Methods: The K-CSE scale was developed through forward-backward translation methods. Construct and criterion validity and internal consistency reliability were calculated using SPSS/WIN 21.0. Data were collected from 257 women students from two universities in G city, South Korea. Results: The factor structure of the K-CSE scale showed the cumulative variance as 62.9% in the factor analysis. Factor loading of 13 items on four subscales ranged from .47 to .88. Factors were named as 'initiative of contraceptive use', 'sexual assertiveness', 'refusal of sexual intercourse', and 'autonomic sexual behavior'. Criterion validity compared to the Sexual Autonomy Measurement (SAM) showed significant correlation. Cronbach's ${\alpha}$ for the reliability of each subscale were .50~.82 and .76 for the total scale. Conclusion: The findings of this study demonstrate that the K-CSE scale is a satisfactory valid and reliable scale. Therefore, the CSE scale can be useful in measuring contraceptive self-efficacy among women university students in Korea.

This paper examines the application of structural reliability analysis to submarine pressure hulls to clarify the merits of probabilistic approach in respect thereof. Ultimate strength prediction methods which take the inelastic behavior of ring-stiffened cylindrical shells and hemi-spherical shells into account are reviewed. The modeling uncertainties in terms of bias and coefficient of variation for failure prediction methods in current design guidelines are defined by evaluating the compiled experimental data. A simple ultimate strength formulation for ring-stiffened cylinders taking into account the interaction between local and global failure modes and an ultimate strength formula for hemispherical shells which have better accuracy and reliability than current design codes are taken as basis for reliability analysis. The effects of randomness of geometrical and material properties on failure are assessed by a prelimnary study on reference models. By evaluation of sensitivity factors important variables are determined and comparesons are made with conclusions of previous reliability studies.
