The purpose of this study is to find options which reduce the job stress and to enhance morale through a variable analysis, and also apply this data in the legal and administration fields. The data for the research was obtained from 217 dental hygienists working in the dental clinics, dental hospitals and university's dental hospitals' in Seoul. The tool used by this study was a Questionnaire measuring on-the-job stress of dental hygienists, was a modified and revised. The Questionnaire version used to measure bank's job stress and used to suggest options by Dae-ha Yoon(1991). Classification of items for measuring job stress was based on Theoretical Study on Job Stress by Dae-hyon Song(1986). The scale used in study was the two points (yes or no in the job stress) scale measuring for variables. The period of data collection was 30 days from December 4, 1995 to January 5, 1996. The methods of data collection were self-writing, direct visit, and postal Questionnaire answering, 224 copies of Questionnaire data were collected, but only 217 copies were used. 7 copies could not be analyzed, were not used for this study. The data analysis was conducted by SPSS after coding the collected raw data. The general characteristics was obtained from real digits and percentages. In order to analyze the difference of sub-variables against the job stress based on general characteristics. Mean, Standard Deviation, and F test (ANDVA) were conducted. The following were the results of job stress variables: 1. Meaningful variable affecting the working organization, is compensation system(p〈0.03). 2. Meaningful variable affecting the working period, is work overload(p〈0.02). 3. Meaningful variable affecting average patients per day, is the career management and payment(p〈0.04, p〈0.01). 4. Meaningful variable affecting number of staff, is the comrade relationship, role conflict among patients, work overload, and job overload(p〈0.000, p〈0.05, p〈0.04, p〈0.01). The comrade relationship is most affected to the number of staffs aides. 5. Meaningful variables affecting job diversion, are the desire and value, the non-role play, and the environment(p〈0.003, p〈0.02, p〈0.005).

Purpose: This study aimed to explore frontline nurses' experience of patient-centered care and understand the factors affecting its implementation in hospitals. Methods: Four focus group interviews were conducted with 30 nurses in two university hospitals. The following theoretical framework of patient-centered care was used: 1) Respect for patients' values, preferences, and expressed needs, 2) Care coordination and integration, 3) Information, communication, and education, 4) Physical comfort, 5) Emotional support and alleviation of fear and anxiety, 6) Involvement of family and friends, 7) Care transition and continuity, and 8) System issues. We performed a directed content analysis. Results: The most frequent patient-centered nursing practices of the hospital nurses were "promoting physical comfort" in inpatient settings and "providing information and communicating" in outpatient settings. The factors influencing patient-centered nursing included the health professionals' mindfulness, work overload and staff shortage, and unreasonable social demands and regulations. Conclusion: A more comprehensive patient-centered nursing practice should be implemented by improving "care transition and continuity," "family/caregiver involvement," and "system building." Health professionals' mindfulness is significant, and organizational supports addressing work overload and staff shortage are needed alongside change in social awareness.

Purpose: This study was conducted to assess the factors affecting turnover intention of the nurses working in neonatal intensive care units, including the extent of fatigue, work stresses, and work overload related to infection control. Methods: This was a descriptive correlational study to test factors affecting the turnover intention of the nurses working in neonatal intensive care units. Data was analyzed utilizing descriptive statistics, t-test, One-way ANOVA, Pearsons' Correlation Coefficient, and multiple regressions by using the IBM SPSS Statistics 23.0 Program(IBM Corp., Armonk, NY). Results: The turnover intention of nurses had a positive correlation with the extent of fatigue (r=.54, p<.001), work stress (r=.40, p<.001), and with the work overload (r=.43, p<.001) related to infection control. In addition, factors affecting the turnover intention of nurses included the extent of fatigue (β=.52, p<.001) related to infection control and the number of pediatric patients assigned to each nurse (β=.26, p=.001) and the variances explained by the regression model was 37.0%. Conclusion: It is necessary to establish and implement strategies to lower the extent of fatigue related to infection control by reducing the nurses' workload. Securing additional nurses to ensure an appropriate number of pediatric patients assigned to each nurse, and providing efficient management and available resources to reduce the turnover intention of nurses working in neonatal intensive care units are suggested.

Purpose: This study was to identify the relationship among clinical nurse's job overload, self-efficacy, emotional exhaust and turnover intention. Methods: The study was conducted through a survey on 537 clinical nurses in five general hospitals. The data were collected by self-reporting questionnaires and analysed by the SPSS/WIN 17.0 program using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: The mean score of turnover intention was 3.04. Turnover intention according to age, total career, job objective, and work off showed significant differences. The significant positive correlations between emotional exhaust and turnover intention (r=.531, p<.001), job overload and turnover intention (r=.514, p<.001) were found. The significant factors influencing turnover intention were emotional exhaust (${\beta}$=.488, p<.001), career (${\beta}$=.175, p<.001), job overload (${\beta}$=.119, p= .003), and number of night (${\beta}$=.117, p=.002), which accounted for 40.3% of the variance. Conclusion: Thought this result, nursing managers should analyze the reasons for high turnover intention, focusing on the main factors affecting turnover intention and consider the solutions to decrease the turnover intention.

This paper examined the relationship between job stressor and job satisfaction according to the general property of disabled workers. Role ambiguity, role conflict, and role overload were cast as the factors of job satisfaction to explore their relationship with the general property and type of disabled workers. The results revealed that role ambiguity had the strongest meaningful relationships with job satisfaction and role conflict, role overload had not shown the meaningful relationships with their Job satisfaction. The reason of this results seemed to be from the fact that the work type available or not available to disabled worker was determined beforehand according to their disability type. Finally, these findings provide a guidelines of efficiency human resource management and strategic development program for the disabled workers.

The load interaction effect can be best illustrated by the phenomenon of overload retardation. Some prediction methods for retardation are reviewed and the problems discussed in the present paper. The so-called under-load effect much of the retardation disappears if a very low level minimum stress follows the overload, is also of importance for a prediction model to work properly under random load spectrum. The concept of Interactive Zone (IZ) fully considering reversed plasticity during unloading was discussed. This IZ concept can be combined with existing models to derive some improved models that can naturally take account of the under-load effect. Some simulations by IZ improved models for test under complex load sequences including multiple overloads and both over/under loads are compared with test results. It is seen that the improvement by IZ concept greatly enhanced the ability of existing models to accommodate complex load interaction effects.
