Purpose - This study was conducted to evaluate service quality, perceived value, and satisfaction in the performing arts in order to establish a system of relationships that predicts repurchase intention, which increasingly needs to be studied as the domestic performing arts market grows. Research design, data, and methodology - Another purpose of this study is to identify 'work-related factors' and 'performing-arts-related factors' in the performing arts industry, and to observe the influence of the core SQ factors expected to influence audiences' purchase intentions through perceived value and customer satisfaction. The empirical study to test the hypothesis was based on a review of the literature and employed the survey method; data were collected from a total of 500 audience members. Results - The major results of the analysis are as follows. First, in terms of quality factors affecting perceived value, literary quality, level, professionalism, and musical quality were shown to have a significant influence as key factors from the performing arts perspective, while reliability, convenience, and related costs were indicated to exert a significant influence as additional factors related to work. Secondly, the quality factors with a significant influence on customer satisfaction were literary quality, professionalism, and musical quality, which were shown to have a significant influence from the performing arts perspective, while only reliability was indicated to exert a significant influence on work-related factors. Third, perceived value was shown to have a strong positive (+) influence on customer satisfaction, with both perceived value and customer satisfaction exerting a significant influence on the revisit intention. Finally, according to the results a difference analysis with demographic variables, viewing variables as moderating variables, differences according to gender were indicated in the influence of literary value and lel on perceived value, and in the influence of convenience and professionalism on customer satisfaction as well. Also, in terms of the influence of perceived value on customer satisfaction, males were found to be more influenced than females. Conclusions - Based on the above results, the suggested implications of the present study are as follows. First, through the consideration of not only the crucial work perspective in performing arts services, which has been inadequate in the past, but the additional performance-related level, the previously unevenly distributed viewpoints were expanded for application. Second, in verifying the relationship between expanded quality factors and the factors that determine consumer behavior while simultaneously considering key factors and additional related factors, work-related service quality factors were shown to exert a stronger influence on perceived value and customer satisfaction than performance-related factors. Third, for service factors related to performance, the reliability factor exerts an influence on perceived value and customer satisfaction, requiring that a performance planner secure and manage diverse channels to immediately support customer requests in providing performance theater services.

The following lessons have been learned from the application of reliability methods in the practice of geotechnical engineering: 1. Establishing Goals Is Important; 2. Mitigating Consequences Can Be Effective; 3. Performance Depends on Systems; 4. Physical Factors Are Important in Statistical Models; 5. Too Much and Too Little Conservatism Are Both Problems; 6. Value of Information Depends on Decision Making; and 7. Effective Communication Is Essential. While the potential for application of reliability methods in the future is unlimited, there are major needs related to each of these lessons that will have to be addressed in order to realize this potential.

Purpose: The purpose of this study was to develop a health conservation scale with high validity and reliability for institutionalized elderly. Method: The process of development of this scale was as follows. A conceptual framework composed of 4 phases of health conservation of institutionalized elderly was identified based on the literature review with elderlies and discussions with experts in health conservation. A total of 75 items, on a 4-point scale were developed. Through reliability testing and factor analysis, 57 preliminary items were selected. By means of internal consistency of the 57 items, 18 items whose inner-items correlation coefficient was below .40 were deleted. Through factor analysis, 2 items whose factor loading was below .40 were deleted. Finally 37 items remained. To verity the 37 items, factor analysis, reliability testing, and correlation was done. Data were collected from 207 institutionalized elderly subjects in Daegu, Kyungpook, Busan, and KyungNam Province from August. 2003 to February. 2004. Result: In the result of factor analysis of the 37 items, 4 factors were extracted. These factors were labeled as ‘personal integrity’, ‘conservation of energy', ‘structural integrity’, and ‘social integrity'. These factors included 4 phases of health conservation. Cronbach's Alpha of 37 the items was .9424 and the correlation coefficient of HPLP was .723. Conclusion: The researchers recommend the following: An explorative study on the variables related to health conservation is needed for criterion validity of this scale. Studies on health conservation of different age groups, and subjects are needed for verification.

The purpose of this study was to evaluate the validity and reliability of the Penn Interactive Peer Play Scale (PIPPS) for Korean young children, with a special confirmative factor analysis. The participants were composed of 435 5-to 6-year-old children and their parents, and 42 teachers. The instruments included the 32-item exploratory PIPPS (Choi & Shin, 2008), the Preschool Behavior Questionnaire (PBQ; Park, 1992), and the PIPPS on parental reporting. The PIPPS was confirmed, and supported the following constructs resulting in the investigation of 3 factors, 'play disruption', 'play interaction', and 'play disconnection', along with 30 items similar to the PIPPS (2008). Inter-correlations between the sub-factors of PIPPS with those of criterion measures were validated by ratings from the PBQ and the parent version of the PIPPS. The reliability coefficients of the sub-factors of the PIPPS ranged from .85 to .92. In conclusion, 3 factor structure of the PIPPS was appropriate to represent the interactive peer play of Korean young children.

Service life assessments which do not include the synergy between mechanical and environmental loading are neglecting a factor that can have a significant impact on structural safety and durability assessment. The degradation of concrete structure is a result of the combined effect of environmental and mechanical factors. In order to make service life design realistic it is necessary to consider both of these factors acting simultaneously. This paper deals with the advanced modelling of concrete carbonation and chloride ingress into concrete using stochastic 1D and 2D models. Widely accepted models incorporated into the new fib Model Code 2010 are extended to include factors that reflect the coupled effects of mechanical and environmental loads on the durability and reliability of reinforced concrete structures. An example of cooling tower degradation by carbonation and an example of a bended reinforced concrete beam kept for several years in salt fog are numerically studied to show the capability of the stochastic approach. The modelled degradation measures are compared with experimental results, leading to good agreement.
