The effects of job stress factors on psychological job stress and job satisfaction levels of school dietitians were evaluated. Questionnaires were distributed to 163 elementary school foodservice dietitians in the Seoul and Incheon area. Statistical data analysis was completed using the SPSS program. The highest stress factor was the importance of the job followed by role ambiguity, autonomy and identity, communication and participation. When dealing with job stress, the subjects showed improved and positive behaviors when communicating and participating with each other. The analysis of the relationships between job stress factors and job satisfaction revealed that the importance of the job had a negative effect on jog satisfaction. while role conflict and overload, personal relationships, and experience accumulation had positive effects. Ample occupational experience and background had highly positive effects on school dietitians' job satisfaction level whereas negative results were shown concerning circulated appointments(p<0.01). Based on these results, we suggest that role conflict and overload should be reduced in order to lower job stress levels and enhance job satisfaction levels.

Recently, Luu suggested fatigue life equation that uses every term of the Crossland equation with stress gradient effect. Luu’s model, however, has a limit of being unable to coverage small radii that are less than a specified length. Furthermore, rolling model has a very small contact area compared to the rolling element size, and fatigue failure occurs on the small radius such as surface asperity by cyclic loading. Therefore, it is necessary to modify fatigue life equation in order to enable fatigue analysis for a small radius. In this paper, the fatigue life considering a stress gradient effect in rolling contact was obtained using Luu’s modified equation. Fatigue analysis was performed to study the effect of stress gradient on the fatigue life using newly adopted equation and to compare the results with pervious models. In order to do this, a series of simulation such as surface stress analysis, subsurface stress analysis, and fatigue analysis are conducted for two rolling balls of same size that contact each other. Through such a series of processes, the fatigue life can be calculated and equation that is proposed in this paper evaluates the fatigue life in case the contact area is small.

Purpose: This study investigated the relationship between degree of stress and quality of life in mothers of children with cerebral palsy. Methods: This study's subjects were 77 mothers of children under 10 years of age with cerebral palsy. The instrument is a self-administered, structured, written questionnaire. The tool that measured the degree of stress was created by modifying the questionnaire by Park (2004). Quality of life for all mothers with cerebral palsy was evaluated by the ShortForm-36 Health Questionnaire. To verify the effects on degree of stress and quality of life arising from general characteristics, t-tests and ANOVAs were conducted. The correlation between degree of stress and quality of life was analyzed via Pearson's correlation analysis. Results: The mothers' degree of stress was rated as 2.69 out of 5; their quality of life was rated as 53.07 out of 100. There was a significant negative correlation between quality of life and the age of cerebral palsy and positive correlations between quality of life and mother's age, background, and family income. Degree of stress among mothers has a positive correlation with quality of life. Conclusion: This study provides basic data about the relationship between degree of stress and quality of life in mothers of children with cerebral palsy.
