Purpose: This present study has been conducted on female workers' shorter working hours in order to look into their fatigue level and the correlation between fatigue and working hours. Method: We surveyed 237 respondents using a questionnaire from June 1st to June 20th, 2005. Results: The means of total fatigue complaint was 3.45. The fatigue level was significantly higher in the lower age group, unmarried group, manager group and shorter working duration group. And the fatigue level was significantly correlated to working hours and work intensity. In the results of stepwise multiple regression, factors affecting the fatigue level were the change of work intensity, age, regular diet habit, working hours and the type of occupation. Conclusion: It is necessary to prepare the health promotion programs, which can reduce female workers' fatigue level and relieve the intensity of their works.

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.

Purpose: The purpose of this study was to evaluate the effectiveness of foot reflexology on fatigue, sleep and pain. Methods: A systematic review and meta-analysis were conducted. Electronic database and manual searches were conducted on all published studies reporting the effects of foot reflexology on fatigue, sleep, and pain. Forty four studies were eligible including 15 studies associated with fatigue, 18 with sleep, and 11 with pain. The effects of foot reflexology were analyzed using Comprehensive Meta-Analysis Version 2.0. The homogeneity and the fail-safe N were calculated. Moreover, a funnel plot was used to assess publication bias. Results: The effects on fatigue, sleep, and pain were not homogeneous and ranged from 0.63 to 5.29, 0.01 to 3.22, and 0.43 to 2.67, respectively. The weighted averages for fatigue, sleep, and pain were 1.43, 1.19, and 1.35, respectively. No publication bias was detected as evaluated by fail-safe N. Foot reflexology had a larger effect on fatigue and sleep and a smaller effect on pain. Conclusion: This meta-analysis indicates that foot reflexology is a useful nursing intervention to relieve fatigue and to promote sleep. Further studies are needed to evaluate the effects of foot reflexology on outcome variables other than fatigue, sleep and pain.

The problem of residual stresses and fatigue behavior in welded structures is the main concern of welding research fields. The residual stresses and distortions of structures by welding exert negative effect on the safety of mechanical structures. Postweld heat treatment is usually carried out to relieve this residual stresses of welded joints. In this paper the influence of postweld heat treatment on fatigue life of butt-welded joint was investigated. To predict the effect of PWHT, an analytical model is developed by finite element and local strain approach and the result of fatigue life analysis is compared to experimental results. It is demonstrated that fatigue life estimates closely approximate the experimental results and PWHT provides some increase of fatigue lives in long-life fatigue region and no increase in short-life fatigue region because of the residual stress relaxation under tensile loads.

The purpose of this study is to investigate the level of fatigue, depression and sleep disorders and to find the correlation between them in patients with chronic liver disease. Methods: The participants consisted of 130 patients with chronic liver disease who visited the C University Hospital in Daegu, Korea from July to August, 2011. Data were collected by a self-reporting questionnaire of the Revised Piper Fatigue Scale, Depression Inventory (BDI) and Sleep Scale. Collected data were analyzed by using PASW Statistics 18.0 program for descriptive statistics, T-test, one-way ANOVA and Correlation Analysis. Results: There were significant differences in fatigue scores (t=8.415, $p$=.004) and depression scores (t=10.08, $p$=.002) between subjects with symptoms of liver disease and those with no symptoms. There was no significant difference in sleep disorder scores. In addition, there is a significant correlation between fatigue and depression (r=.641), linking fatigue and sleep disorders (r=.578), and between depression and sleep disorders (r=.572). Conclusion: It is necessary to develop multidisciplinary intervention programs to relieve patientsuffering.

This study is about a service that allows people to naturally learn to bask in the sun, which is a habit to relieve depression. Modern people do not have enough time to bask in the sun due to their busy lives, and as a result, depression and fatigue are increasing day by day. Therefore, in order to relieve depression, there is a need for the development of technology to manage the schedule of sunlight basking so that users can experience sunlight more naturally. The sunlight service developed through this study can help you easily plan your sunlight schedule by recommending good dates, times, and locations for sunbathing. In addition, users can receive coins as much as they bask in the sun, and they can be motivated by the act of basking in the sun by raising their character with those coins.

Objective: Chicken essence and branched chain amino acid (BCAA) supplementation has been recognized to significantly relieve fatigue. To obtain chicken essence with high amounts of BCAA, spent hens herein was used to prepare dripped chicken essence (SCE) and compared with commercial dripped chicken essence (CCE) for in vivo anti-fatigue effect. Methods: To determine the effect on anti-fatigue by dripped chicken essence, the exhaustive swimming was performed. Thirty-two 7-week ICR mice were divided into four groups, which included the control group (CG), CCE, SCE-1X and SCE-2X. The mice were given daily oral administration (0.012 mL/g body weight/d). The fatigue index analysis was conducted weekly. Results: The results showed that SCE had a higher BCAA level as expected, and mice treated with dripped chicken essence (CCE and SCE) could significantly improve exercise performance. The lower blood lactate level, blood urea nitrogen level and creatine phosphokinase activity were found in the supplement of SCE group compared with the CCE group, which suggested that the SCE possessed strong anti-fatigue ability. This could possibly be due to the higher content of BCAA. Conclusion: In this study, SCE promoted recovery from physical fatigue in mice and elevated endurance ability. Among them, the double dose (SCE-2X) showed the strongest anti-fatigue ability. Taken together, spent chickens could be a good source of chicken essence to improve the effect of anti-fatigue.
