In the trackbed design using elastic multilayer model, the stress-dependent resilient modulus $(E_R)$ is an important input parameter, that is, reflects substructure performance under repeated traffic loading. However, the evaluation method for resilient modulus using repeated loading triaxial test is not fully developed for practical purpose, because of costly equipment and the significantly fluctuated values depending on the testing equipment and laboratory personnel. The this study, the paper will present an indirect method to estimate the resilient modulus using dynamic properties. The resilient modulus of crushed stone, which is the typical material of sub-ballast, was calculated with the measured dynamic properties and the range of stress level of the sub-ballast, and approximated with the power model combined with bulk and deviatoric stresses. The resilient modulus of coarse grained material decreases with increasing deviatoric stress at a confining pressure, and increases with increasing bulk stress. Sandy soil (SM classified from Unified Soil Classification System) of subgrade was also evaluated and best fitted with the power model of deviatoric stress only.

The purpose of this research is to figure out the effects of media framing and image restoration strategies on the public's crisis perceptions. The literature review revealed that the public perceives crises through the media lens and image restoration strategies heralded by the organization interact with media frames in the process of the public's perceiving the crisis. The news content analysis and the experiment were conducted to accomplish the research purpose. Also food-related crises were selected for a research case because they have a great impact on the society. The content analysis showed that image restoration strategies designed by the crisis organization tend to be conveyed through anecdote-type news frames. Most image restoration strategies were close to defensive communications and not differentiated by the crisis type. The experiment outcomes demonstrated that the organization's image restoration strategies were not consistent with what the public preferred in the crisis situation. Such public perceptions also were changed according to media frames. Media frames and image restoration strategies have an interaction effect on the public's crisis perception.

This study attempted to examine the role of customers in service recovery process. There have been an argument regarding whether the role of customer in service failure situation 'buffer' or 'deteriorate'. Thus, the role of customer such as relationship quality and customer participation was discussed in this research. According to the result of study, (1) customers' perceived recovery have positive effect on positive emotion significantly. (2) customers' perceived distributional justice and interactional justice positively affected encounter satisfaction in the of recovery justice variable. However, whereas procedure justice has no effect on encounter satisfaction directly, there was indirect effect through customers' positive emotion. (3) As a result of the analysis for the effect of perception of recovery justice on recovery satisfaction, the effect of interactional justice was significant only. Distributional and procedural justice have indirect effect on recovery satisfaction through positive emotion or encounter satisfaction. (4) Customers' positive emotion positively affected encounter satisfaction and recovery satisfaction. (5) Relationship quality negatively moderated the relationship between procedural justice and positive emotion while customer participation positively moderated two paths that distributional justice to encounter satisfaction and interactional justice to recovery satisfaction.

Emotional labor may lead to service failure in service industries. Managers of an organization or a company can contribute to service recovery by reducing stress related to emotional labor. The aim of this study is to identify the antecedents and consequences of service recovery in respect of emotional labor. Data was surveyed from frontline employees to achieve the research purpose. The hypotheses were examined empirically using statistical tools. Results are as follows. First, surface acting had a negative impact on service recovery performance and deep acting had a positive impact. Second, empowerment and motivation had an influential relationship positively on service recovery performance. Third, service recovery performance was negatively related to intention to quit. In conclusion, managing employees' emotional labor strategies and work environment will bring high service recovery performance and low intention to quit.

The rates of escision repair at various doses and times after MNNG treatment in CHO cells were compared with the frequencies of chromosome aberrations to determine a possible relation between there two types of biological phenomena, and the results obtained were as follows: 1. the MNNG-induced excision repair was dose-dependent in te ranges between $0.5 \\times 10^-5$M. The maximum rate of excision repair was occurred in the cells soon after the treatment. The rates were then gradually decreased and appeared about 66% of 0 hour at 24 hours. 2. The rates of chromosome aberrations induced by MNNG was the highest at 6 hours, in which majority were chromatid deletions. The rates of chromatid deletions decreased, whereas chromatid exchanges increased with time, resulting is about equal rates at 24 hours after treatment. 3. The rates of excision repair at different times after MNNG treatment were roughly related to the total breaks per cell. The rates, however, did not show any relation to either chromatid exchanges or deletions. These results may suggest that excision repair may not be directly related to chromosome aberrations in MNNG treated CHO cells.

This paper aims to examine the effects of perceived justice of service recovery efforts on the customer relationship performance in mobile social commerce. To this end, we classified cognitive-affective trusts and post-recovery satisfaction into the customer relationship performance. This research employs a field survey of customers who experienced service failures in mobile social commerce and a covariance structural model analysis in order to test hypotheses of our research model. The findings present that all justices of service recovery efforts positively affect the cognitive trust, whereas the only procedural justice significantly influences the affective trust. In addition, the results show that cognitive-affective trusts have a positive effect on the post-recovery satisfaction. Our results suggest practical implications that are used to help managers maintain and improve relations with the customers who experienced service failures and to increase the post-recovery satisfaction.

The purpose of this study was to identify the convergence that resilience has on clinical performance ability and stress in clinical practice in order to prepare effective educational materials for clinical practice. The results showed that satisfaction of university life, satisfaction of nursing major and satisfaction of clinical practice had significant effects on resilience, clinical performance ability and stress in clinical practice. Also the correlation between the resilience and clinical performance ability of nursing students was positive(r=.510). And the correlation between the resilience and stress in clinical practice was negative(r=-.153). These findings indicate that there is a need to improve resilience of nursing students to promote the clinical performance ability and to lessen stress in clinical practice. The results should be reflected in the development of effective programs.

This study investigates the effects of justice dimensions on negative emotion, consumer satisfaction after service recovery, repurchase intention and word-of-mouth intention in a context of service recovery. Behavioral intentions(repurchase intention and word-of-mouth intention) are critical to the discount store sellers' survival and success. The research model is an extension of previous studies, especially considering more recent developments in the service recovery literature. A survey using 458 customers in China was conducted, confirmatory factor analysis was conducted to test the validity of the measurement model, and AMOS analysis approach was used to gain important insights into how customer retention in the discount store business can be ensured. The results suggest that all three dimensions of justice had negative effects on negative emotion, had positive effects on satisfaction after service recovery. Negative emotion had negative effects on recovery satisfaction. Recovery satisfaction had positive effects on repurchase intention and word-of-mouth intention. Finally, this study suggests the implications of these findings and offers directions for future research.
