Purpose: This study was conducted to assess stressful life events and quality of life in nursing students. Methods: We performed a cross-sectional research design. A structured questionnaire was designed to collect data on participants' socio-demographics, stressful life events (interpersonal relationship & task-related events) and quality of life (WHOQOL-Bref) in September 2011. Descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficient and hierarchical multiple regression were applied to data analysis. Results: A total of 135 nursing students were surveyed. The score of the task-related stressful life events was higher than that of the interpersonal stressful life events. Physical domain score ($13.53{\pm}2.33$) was highest but environmental domain score ($12.75{\pm}2.34$) was lowest in quality of life. Satisfaction with campus life affected stressful life events (F=11.82, p<.001) and quality of life (F=17.77, p<.001), and extracurricular activities affect quality of life (t=-2.51, p=.013). Quality of life was negatively associated with task-related stressful life events (r=.-51, p<.001). Multiple regression analyses showed that extracurricular activities, satisfaction with campus life and task-related stressful life events were statistically significant in predicting quality of life with the explanatory power of 40.6%. Conclusion: This study could be a reference to improve the quality of life of nursing students.

Performance-based remaining life assessment of reinforced concrete bridge girders, subject to chloride-induced corrosion of reinforcement, is addressed in this paper. Towards this, a methodology that takes into consideration the human judgmental aspects in expert decision making regarding condition state assessment is proposed. The condition of the bridge girder is specified by the assignment of a condition state from a set of predefined condition states, considering both serviceability- and ultimate- limit states, and, the performance of the bridge girder is described using performability measure. A non-homogeneous Markov chain is used for modelling the stochastic evolution of condition state of the bridge girder with time. The thinking process of the expert in condition state assessment is modelled within a probabilistic framework using Brunswikian theory and probabilistic mental models. The remaining life is determined as the time over which the performance of the girder is above the required performance level. The usefulness of the methodology is illustrated through the remaining life assessment of a reinforced concrete T-beam bridge girder.

The purpose of this study was to investigate the effect of empathic ability and campus life stress on the stress coping behaviors among 395 dental hygiene students. The analysis was performed using PASW Statistics ver. 18.0, and the following conclusions were obtained. The empathic concern factor was the highest in the subscale of empathic ability (3.60). The interpersonal relationship stress was 1.65 and the task-related stress was 2.72. The stress coping behaviors were the highest among the sub-domains, with 3.69 for wishful thinking. The differences of stress coping behaviors according to general characteristics were as follows. The lower the age and grade, the higher the problem-focused coping; when they were religious there was a high pursuit of seeking social support. When they were satisfied with their economic level, wishful thinking was high. There was a low negative correlation between empathic concern and interpersonal relationship stress in campus life (p<0.01). There was a positive correlation between personal distress and task-related stress (p<0.001). The relationship between empathic ability and stress coping behaviors was most associated with personal distress and wishful thinking. Among the sub-domains of stress coping behaviors, factors that have a common impact on personal distress and seeking social support are viewpoint acceptance. Factors supporting emotional focus and wishful thinking were task-related stress. Dental hygiene students are not able to completely eliminate the stress that they are actually under. However, as the research results show, it is necessary to use stress coping techniques to cope effectively with individual tendencies and situations, and to improve the ability to sympathize with another individual.
