Purpose: This survey aimed to find out the relationship of work stress, self-efficacy, and task performance of the preceptor. Method: The data of this study were collected from 215 Preceptors who have been working in four hospitals in Deajeon. The data were analyzed by t-test, ANOVA and Duncan test for group differences, Pearson's correlation and Multiple Linear Regression with SPSS WIN 17.0 program. Result: There were significant positive relations between the work stress (r=0.193, p<0.05), self-efficacy (r=0.346, p<0.00), and the task performance of preceptor. The most predictive factors of the task performance were self-efficacy(11.5%), the job stress(2.7%), and age(2.0%). Conclusion: Nursing department supervisors need to manage preceptor to reduce work stress and to improve self-efficacy. It is recommended that work stress should be decreased and programs for increasing self-efficacy need developing in order to satisfy self-realization of preceptors and their needs.

Purpose: To examine the relations among occupational satisfaction, stress, and customer orientation of upper-scale general hospital nurses. Method: We studied with structured questionnaires with total 66 questions for 218 nurses working at university hospitals in Gangwon-do from February 2 to 22, 2010. Result: Occupational satisfaction and customer-oriented character increased when nurses' ages and career experiences were higher, married, working in daytime without shift and in higher positions. Occupational stress increased when nurses were younger, not married, with three shifts, and when they were general nurses. However, there was no statistical difference. Customer-oriented character had positive correlation with occupational satisfaction and stress while occupational satisfaction had negative correlation(r=-0.358) with occupational stress. Conclusion: As occupational stress and satisfaction of nurses in university hospitals showed significant relations with customer-oriented character, t is necessary to reduce occupational stress of nurses, and strengthen occupational satisfaction of them.

The purpose of this study is to analyze the impact of shot peening angle on residual stress distribution. From the residual stress analysis of perpendicular shot peening, it could be known that the residual stress in the case of high velocity is larger than low velocity, but the amount of shot size has little effect on the magnitude of compressive residual stress. The centroidal residual stress is not greatly affected by the inclined shot peening but mainly related to the unstable conditions of surface residual stress field. Therefore, this tendency may lead to reduce fatigue life of treated material.

Turbulent boundary layer pressure fluctuation exerted on the surface of a structure can give rise to a elastic stress wave on the surface of the structure. The stress wave so called surface wave, will not only propagate along the surface of structure but also penerate into the structure. To reduce the transmission of stress wave into the structure the elastomer layer is usually attactched on the surface of structure. The transfer function, which is defined herein as the ratio of stress waves at the surface and bottom of the elastomer layer, is derved by use of the cylindrical coordinates system. The elastodynamics of the elastomer layer subjected to the turbulent boundary layer pressure fluctuation is represented by the simplified one degree-of-freedom model for easy prediction of the stress wave transmission as well as efficient design of the elastomer layer.

The purpose of this study was to examine the relationships between child-mother 'goodness-of-fit', mothers' empathy and parenting stress. A sample of 324 mothers of 5th graders in the Seoul Metropolitan area participated in this study. Mothers answered questionnaires on the levels of their parenting stress, empathy and child-mother 'goodness-of-fit'. Data were analyzed using Pearson's correlation coefficients, as well as multiple and hierarchical regressions. Child-mother 'goodness-of-fit', as well as mothers' empathy was a predictor for parenting stress; significant interaction effects were found between child-mother 'goodness-of-fit' and the mothers' empathy on parenting stress. These results indicate the need for possible intervention in relation to mothers' empathy levels and to reduce parenting stress.

Purpose: The purpose of this study was to identify the relationship between occupational stress and depression of construction workers. Methods: The subjects were 168 construction workers selected from I city and K city in Korea by convenient sampling. The data were collected by self-report questionnaires from August 1 to 31, 2011. The data were analyzed by frequencies, t-test, ANOVA, Tukey test, Pearson correlation coefficient, stepwise multiple linear regression with the SPSS/WIN 15.0 program. Results: The total mean scores of occupational stress on the subjects were 46.65 and lower (below 50%) than those of the Korean male workers, standard. According to the CES-D cut-off point, the prevalence of depression was 25%. The study showed that occupational stress is positively correlated with depression. Conclusion: This study concludes that it is necessary to develop stress management program to reduce occupational stress and depression.

Purpose: This study was aimed at identifying the levels of parenting stress among mothers of children with cerebral palsy and factors influencing parenting stress. Method: The research design was cross-sectional survey. Data were collected from 122 mothers of hospitalized children (under 15 years of age) with cerebral palsy at the Y medical center using the questionnaires. The data were analyzed using one way analysis of variance with Scheffe test for post-hoc analysis or t-test, Pearson correlation, and stepwise multiple regression. Results: The mean score of parenting stress was 2.52 (SD=0.79; range: 1~4). The father's participation, mother's parenting hours, self-esteem and social support were significant predictors of parenting stress, significantly accounting for the 33.3% variance (F=16.118, p<.001). Conclusion: It is essential for health professionals to consider the aforementioned four factors when developing interventions to reduce parenting stress for mothers of children with cerebral palsy.

The fatigue strength of welded joint is influenced by the welding residual stress which is relaxed depending on local stress distributed in vicinity of stress raisers, eg. under cut, overlap and blow hole. To evaluate its fatigue life the geometry of the stress raisers and the welding residual stress should be taken into account. The several methods based on notch strain approach have been proposed in order to consider the two factors above mentioned. These methods, however, have shown considerable differences between analytical and experimental results. It is due to the fact that the amount of the relaxed welding residual stress evaluated by the cyclic stress-strain relationship do not correspond with that occurred in reality. In this paper the residual stress relaxation model based on experimental results was used in order to reduce the discrepancy of the estimated amount of the relaxed welding residual stress. Under an assumption of the superimposition of the relaxed welding residual stress and the local stress, a modified notch strain approach was proposed and verified to the cruciform welded joint.

This study was conducted to arrange the basic data for the ways to operate the effective nursing programs and reduce job stress by grasping the awareness, satisfaction and job stress of the nurses due to the introduction of EMR(EMR : Electronic Medical Record) system and clarifying the relationship among them. Methods: Of the hospitals which introduced EMR, the study was conducted for 356 nurses who used EMR in a university hospital in D city and the data was collected from June 1 to June 30. The collected data was analyzed with real number, percentage, T-test, ANOVA, and Pearson correlation coefficient. Results: The results of the study above, it could be certified that the higher the satisfaction and awareness of the users of EMR were, the more the job stress of them decreased. Therefore, the qualitative nursing should be provided to the patients by reducing job stress with the improvement of the awareness and satisfaction of the nurses of EMR, and shortening the time in keeping the records of patients, in order to enhance the satisfaction of EMR, there should be a proper management, such as a regular EMR education, and there must be the ways to reduce the job stress of the nurses and strengthen the satisfaction of EMR.
