Purpose: This study aimed to investigate the effect of positive psychological capital, empathy ability, and stress coping style on psychiatric ward nurses' compassion fatigue. Methods: Data were collected using structured questionnaires for 140 psychiatric ward nurses. The data were analyzed using t-test, one-way ANOVA, and hierarchical regression. Results: The variable predictors of compassion fatigue were as follows: positive psychological capital (β=-.35, p<.001), empathy ability (β=.32, p<.001), and passive coping (β=.25, p=.004). These factors explained 27% of compassion fatigue, and psychological capital was found to have the greatest influence among these variables. Conclusion: Positive psychological capital, empathy ability, and passive coping are important factors influencing nurses' compassion fatigue in psychiatric wards. It is necessary to develop interventions and appropriate coping styles that strengthen positive psychological capital to prevent and reduce nurses' compassion fatigue in psychiatric wards. In addition, it is necessary to identify the required level of empathy ability to maintain a therapeutic relationship.

The Purpose of this study was to identify characteristics of fatigue and the relationship between fatigue and related factors in patients on hemodialysis. This study was a survey study using a cross-sectional design. The subjects for this study were 101 patients on hemodialysis who were registered in the six hemodialysis clinics among a total of eleven clinics in Seoul. The period of data collection was from February 28, 1995 to May 2, 1995. Data were collected through an interview with a structured packet and the physiological data. The tools used in this study were the Visual Analogue Scale-Fatigue developed by Lee et al(1990) and translated by Lee(1991), the fatigue interview schedule developed by this researcher, Zung's self rating depression scale(Zung, 1965), the self-efficacy scale developed by Sherer et al(1982) and the Norbeck Social Support Questionnaire(NSSQ) translated by Oh(1984). The collected data were analyzed using descriptive statistics(mean, standard deviation, frequency, range), Pearson correlation coefficients and Stepwise multiple regression. The results were as follows ; 1. Characteristics of Fatigue of hemodialysis patients : 1) 79 of 101 hemodialysis patients complained fatigue. 2) The mean fatigue score as measured by the VAS-F was 36.2mm. 3) The mean duration of fatigue was 2.9 hours 2. Characteristics of fatigue related factors : 1) The physiologic factor which included Hgb, Hct, BUN, creatinine, potassium and interdialytic weight gain deviated from normal range. 2) The psychological factor which included depression and self-efficacy was about the same level as for patients with other chronic diseases. 3) The environmental factor which included social support had wide variation. 3. The relationship between fatigue and related factors : 1) Interdialytic weight gain in the physiologica factor was the only valuable with fatigue （p＜.05） 2) The relationship between fatigue and the psychological factor of depression showed a positive and strong correlation（p＜.05）. According to the findings of this study, fatigue was highly correlated with the depression. This indicates that nurses should try to assess and control psychological factors when patients complain of fatigue rather than just considering physiological factors. Nursing has to develop effective nursing interventions to reduce fatigue in patients with chronic diseases using the relationship between fatigue and physiological, psychological and environmental factors.

Objectives: The objectives of this study were to determine the psychological fatigue and analyze muscle activity of production workers who are performing processes jobs while standing for prolonged time periods. Methods: The psychological fatigue experienced by the workers was obtained through questionnaire surveys. Meanwhile, muscle activity has been analyzed using surface electromyography (sEMG) measurement. Lower extremities muscles include: erector spinae, tibialis anterior, and gastrocnemius were concurrently measured for more than five hours of standing. Twenty male production workers in a metal stamping company participated as subjects in this study. The subjects were required to undergo questionnaire surveys and sEMG measurement. Results: Results of the questionnaire surveys found that all subjects experienced psychological fatigue due to prolonged standing jobs. Similarly, muscle fatigue has been identified through sEMG measurement. Based on the non-parametric statistical test using the Spearman's rank order correlation, the left erector spinae obtained a moderate positive correlation and statistically significant ($r_s$ = 0.552, p < 0.05) between the results of questionnaire surveys and sEMG measurement. Conclusion: Based on this study, the authors concluded that prolonged standing was contributed to psychological fatigue and to muscle fatigue among the production workers.

In this study was proposed that a new estimating method for investigation of contractile state changes which generated from continuous isometric contraction of skeletal muscle. The physiological changes(EMG, ECG) and the psychological changes by CNS(central nervous system) were measured by experiments, while the muscle of subjects contracted continuously with isometric contraction in constant load. The psychological changes were represented as three-step-change named 'fatigue', 'pain' and 'sick(greatly pain)' from oral test, and the method which compared physiological change with psychological change on basis of these three steps was developed. The result of analyzing the physiological signals, EMG and ECG signal changes were observed at the vicinity of judging point in time of psychological changes. Namely, it is supposed that contractile states have three kind of states pattern (stable, fatigue, pain) instead of two states (stable, fatigue).

Purpose: This study was correlation study to identify the factors influencing sleep quality, fatigue, and postnatal depression in mothers who have given birth during the past 6 months. Methods: The study was conducted using a survey with questionnaires to 329 mothers who visited E University Medical Center, or three local clinics located in D city, between August and October 2013. Collected data were analyzed using the SPSS/WIN 20.0 program. Results: Out of 329 subjects, 18.2% showed that they had mild postnatal depression whereas 24.3% had severe postnatal depression. Accordingly, 42.5% reported having postnatal depression. Postnatal depression had a significant correlation with sleep hours after childbirth (r=-.16, p=.003), spousal support (r=-.28, p<.001), sleep quality (r=-.35, p<.001), physical fatigue (r=.66, p<.001), psychological fatigue (r=.69, p<.001), and neurosensory fatigue (r=.56, p< .001). Factors influencing postnatal depression include psychological fatigue, sleep quality, number of child births, and neurosensory fatigue, and these accounted for 53% of postnatal depression. Conclusion: Results indicate that factors influencing postnatal depression involve psychological fatigue, sleep quality, number of child births, and neurosensory fatigue. Therefore for nursing intervention for postpartum mothers, it is necessary to assess the level of depression, fatigue, and sleep quality, and to provide interventions to relieve depression.

Background: Seafaring is an inherently stressful environment. Because working time and leisure time is spent in the same confined environment for a prolonged period of time, many stressors present in seafaring can also be conceived of as chronic. We explored the effects of duration at sea, seafaring experience, environmental stressors, and psychological capital (PsyCap) on the sleep quality and fatigue of seafarers. PsyCap is a construct that draws upon ideas from positive psychology and positive organizational behavior, and is intended to capture an individual's psychological capacities that can be developed and utilized for performance improvements. Methods: We collected survey data from a sample of seafarers working in the offshore re-supply industry (n = 402) and a sample of seafarers working on board combined passenger and cargo ships (n = 340). Results: PsyCap emerged as a robust predictor with statistically significant relations to fatigue and sleep quality in both samples. PsyCap also interacted with duration at sea in explaining fatigue in seafarers working on board the passenger and cargo ships. Seafarers on passenger and cargo ships also reported significantly higher levels of fatigue than those working in the offshore re-supply industry. Conclusion: Coupled with emerging research showing that PsyCap is trainable, our results suggest that maritime organizations could have much to gain by being cognizant of and developing routines for continually developing the PsyCap of their employees.

Fatigue is a universally common word. The subject has been studied in different disciplines, but the basic concept of the term still remains unidentified. It becomes especially important for the medical communications between nurses and clients. Based on the framework outlined by Walker and Avant (1995), this analysis attempts to clarify and examine the symptoms of fatigue. The attributes of fatigue identified in this paper were exhaustion, weighted psychological burden, shortage in capacity or lack of energy, shortage incapacity(motivation and excitement), and imbalance of energy. Therefore, the definition of fatigue refers to a subjective feeling from various internal or external stresses. The consequences of fatigue bring reduced capacity and imbalance of energy. The symptoms show a homeostatic disability or shortage of capacity (physical, psychological, environmental and physiological factors). A precise understanding of "fatigue" will be utilized in defining the causes and measuring outcomes. Also, it will enhance the effective medical communications with client s and nurses. In conclusion, more work is needed to develop objective measurement and effect ivenursing intervention.

The following questionnaires were utilized in this study: a self reported symptom of health and a fatigue-regulation behavior scale originated from Kwon(1997). The analysis for the data was done by SAS program, t-test, ANOVA, and Pearson correlation. The results of this study were as follows 1. Total mean scores of health status were shown 29.1, physical symptom 17.9 and psychological symptom 11.2. According to symptom of body system were higher in muscular-skeletal sympom 5.5, neurologic symptom 3.5, and digestive symptom 2.7. 2. The mean scores of symptom of health were significantly different in duraion of marriage, status of menstruation, perceived fatigue, perceived cause of fatigue, perceived help of family, hours of sleep. Physical symptom was significantly different in years of educational, status of menstruation, perceived fatigue, perceived cause of fatigue, perceived help of family, hours of sleep. Psychological symptom was significantly different in parity, whether or not having past illness, perceived fatigue. 3. The neurologic symptom was significantly different in years of education, status of menstruation, perceived fatigue, time to rest The respiratory symptom was significantly different in years of education, status of menstruation and hours of physical exercise. The muscular-skeletal symptom was significantly different duration of marriage, status of menstruation, BMI. perceived fatigue, perceived cause of fatigue, perceived help of family. The cardiovascular symptom was significantly different in whether or not having religion, number of children, duration of marriage, number of pregnancy & abortion, parity, status of menstruation, BMI. The digestive symptom was significantly different in whether or not having religion and the number of children. The urologic symptom was significantly different in whether or not having job, type of family, status of menstruation, BMI, perceived fatigue, perceived cause of fatigue, perceived help of family.
