The purpose of this study is to compar self-reported fatigue and fatigue-regulating behaviors of rheumatoid arthritic patients and normal persons. This study collected the data from 75 rheumatoid arthritic patents visited the departments of internal medicine or orthopedics of four general hospitals T-city and K-city by means of direct interview and questionnaires. in this study also collected data from 75 normal persons who had not been exposed to any other disease in T-city and K-city by means of direct interviews anti questionnaires which were conducted by two trained nurses. This experiment was conducted from August 1, 1998 to October 15, 1998. This study used both MAP(Multi-Dimentional Assessment of Fatigue) developed by Belza(1995) to measure fatigue and the measurement developed by Kwon, Young-Eun to investigate fatigue regulating behaviors. The collected materials were analyzed by means of descriptive statistics, t-test, and the ANCOVA according to the SPSS PC+ program. The findings are as follows : 1. There was the statistically significant difference(t =5.07, p=.000), between rheumatoid arthritic patients(32.76 points) and normal persons(25.81 points) in t-test comparison by group about fatigue. A fatigue degree of rheumatoid arthritic patient group was high in five kinds of lower realms such as common fatigue degree, fatigue severity to be experienced, distress due to fatigue, daily fatigue degree, and fatigue timing at the last week by dimension. 2. There was the significant difference in the number of fatigue-regulating behaviors between rheumatoid of fatigue arthritic patients(9.37 times) and normal persons (8.15 times), but there wasn't any significant difference in the efficiency between rheumatoid arthritic patients(2.85 points) and normal persons (2.78 points) This research suggests two kinds of things as follows : 1. It is necessary to develop an educational program for improving efficiency of fatigue-regulating behaviors as well as some nursing arbitration measures for reducing fatigue of rheumatoid arthritic patients. 2. It is necessary for the future studies to continuously grasp characteristics of fatigue by gender variable by selecting more rheumatoid arthritic male patients.
Purpose: The purpose of this study was to investigate the relationship among sleep quality, heart rate variability (HRV), fatigue, depression, and anxiety reported by Korean adults. Methods: A cross-sectional study of 208 adults aged 20~60 years was conducted using a short-term HRV analysis and self-reported questionnaires of Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale, Beck Depression Inventory, and State Trait Anxiety Inventory. Results: Subjects with good sleep quality (PSQI $score{\leq}5$) had higher HRV total power (t=2.03, p=.043) and high-frequency (t=2.04, p=.043) with lower fatigue (t=-4.08, p<.001), depressive mood (t=-3.66, p<.001), and trait anxiety (t=-3.84, p<.001) than subjects with poor sleep quality. Poor sleep quality was negatively correlated with HRV total power (r=-.17, p=.016), high-frequency (r=-.14, p=.049), and positively fatigue (r=.39, p<.001), depression (r=.44, p<.001), state anxiety (r=.23, p=.001) and trait anxiety (r=.34, p<.001). Conclusion: The results indicated that sleep quality is correlated with HRV which reflects the activities of the autonomic nerve system, fatigue, depression, and anxiety in adults.
In this paper, the process of predicting efficient durability performance for vibration durability test of automobile parts using vibration test load on automobile fuel tank is presented. First of all, the common standard load that can be applied to the initial development process of the automobile was used for the fuel tank and the vulnerability of the fuel tank to the vibration fatigue load was identified through frequency response analysis. In addition, the vulnerability of the fuel tank was re-enacted through vibration durability test results, and the scale factor was applied to the standard load. In order to predict the vibration durability performance required for detailed design, vibration fatigue analysis was performed on the developed vehicle with the frequency of vibration severity equivalent to the durability test, and the vulnerability and life span of the fuel tank were identified through the process of applying weights to these selected standard loads, thereby reducing the test time of the development vehicle.
Introduction : The aim of this study was to investigate menstrual pattern according to Mibyeong Index(MBI) and compare Mibyeong symptom score according to severity of menstrual pain. Mibyeong Index was designed to measure inconvenience and resilience of subject's complains including four physical symptoms(fatigue, pain, low sleep quality, indigestion) and mental distress including anxiety, anger, depression. Method : We used the clinical data of Korean medicine Date Center(KDC) for subjects who participated in the study of 'Clinical research for collecting of clinical cases based on the personal type of Mibyeng' conducted in Seoul, from June 26, 2015 to June 26, 2017. A total of 566 fertile women aged 30 to 50 who completed the questionnaires were included in this study. In this study, we used items of Mibyeong Index and the menstrual pattern by self-report questionnaires. The date were analyzed through Kruskal Wallis test, Pearson's chi-square test, and one-way ANOVA using SPSS statistics 19.0. Results : Mibyeong status was significantly associated with severity of menstrual pain(p<0.001), worst day of menstrual pain(p<0.05), and type of menstrual pain(low back pain, nausea, depression, and none (respectively, p<0.05)). In addition, The 7-subtype score (fatigue (p<0.001), pain(p<0.001), low sleep quality(p<0.001), indigestion(p<0.001), anxiety(p<0.05), anger(p<0.05) and depression(p<0.05)) of Mibyeong index and total score of Mibyeong Index (p<0.001) showed significant difference for severity of menstrual pain. Conclusion : This result indicates that a close relationship between Mibyeong status and severity of menstrual pain. Further studies are needed but, we hope that this results will be used as the basic data to improve mibyeong status through health care to alleviate dysmenorrhea.
Several damage counting methods can be applied for the fatigue issues of a ground vehicle system using strain data and acceleration data is partially used for a high cyclic loading case. For a vibration test, acceleration data is, however, more useful than strain one owing to the good nature of signal-to-random ratio at acceleration response. The test severity can be judged by the fatigue damage and the pseudo-damage from the acceleration response stated in ISO-16750-3 is one of sound solutions for the vibration test. The comparison of fatigue damages, derived from both acceleration and strain, are analyzed in this study to determine the best choice of fatigue damage over multi-spectral input pattern. Uniaxial excitation test was conducted for a notched simple specimen and response data, both acceleration and strain, are used for the comparison of fatigue damages.
Objectives : Our aim is to evaluate feasibility for massive clinical research and to make basic analysis of efficacy and safety of acupuncture treatment for chronic fatigue syndrome and idiopathic chronic fatigue. Methods : This study is a protocol for a pilot randomized controlled trial. It was developed through literature searches and discussions among researchers. Results : Forty participants allocated to acupuncture group and wait-list group. Participants allocated to acupuncture group will be treated three times per week for a total of 12 sessions over four weeks. Eight points (GV20; bilatral GB20, BL11, BL13, BL15, BL18, BL20, BL23) have been selected for the acupuncture group. Participants in the wait-list group will not receive acupuncture treatment during study period and follow-up will be made in the 5th and 9th weeks after random allocation. Then the same acupuncture treatment as that performed to the acupuncture group will be made to the wait-list group. Fatigue Severity Scale, a short form of Stress Response Inventory, Beck Depression Inventory, and Insomnia Severity Index will be used as outcome variables to evaluate the efficacy of acupuncture. Safety will be assessed at every visit. Conclusions : The trial based on this study will be performed. The results of the trial will provide basis for the efficacy and safety of acupuncture treatment for chronic fatigue syndrome and idiopathic chronic fatigue.
Objectives : The aim of this study was to evaluate the effectiveness and safety of acupuncture for chronic fatigue syndrome and idiopathic chronic fatigue. Methods : A randomized, controlled pilot trial was conducted. Twenty-four participants were randomized into one of the two groups: an acupuncture group(n=12) and wait-list group(n=12). The treatment group received 12 sessions of acupuncture over 4 weeks. Eight points($GV_{20}$; bilateral GB20, $BL_{11}$, $BL_{13}$, $BL_{15}$, $BL_{18}$, $BL_{20}$, and $BL_{23}$) were selected for needling. The control group did not receive acupuncture treatment during study period and follow-up were done in the $5^{th}$ and $9^{th}$ weeks after randomization in both groups. The primary outcome was fatigue severity scale(FSS) and the secondary outcomes included a short form of stress response inventory(SRI-short form), beck depression inventory(BDI), and insomnia severity index(ISI). Safety was assessed at every visit. Results : There were statistically significant differences in the between group values of FSS at $5^{th}$ weeks after randomization(p=0.0002), SRI-short form, BDI, and ISI at $5^{th}$, $9^{th}$ weeks after randomization(p<0.01). There were no adverse events. Conclusions : The results suggest that acupuncture is associated with benefits on the short-term outcomes in chronic fatigue syndrome and idiopathic chronic fatigue.
Objectives: Medically unexplained fatigue includes chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF). These disorders quite impair quality of life while no effective therapies exist. Therefore, patients with CFS or ICF frequently choose treatments based on traditional Korean medicine. The study aimed to analyze characteristic of patients visiting an Oriental clinic with CFS or ICF. Methods: Patients who met criteria for CFS or ICF were enrolled in this study, from March 2011 to Jun 2013. Clinical information focused on symptom differentiation and Sasang constitution was analyzed. Pearson's chi-square test was used to compare the frequency among sub-groups. Results: In total, 77 patients (49 male and 28 female) were diagnosed with CFS (17 male and 13 female) or ICF (32 male and 15 female). The symptom differentiation was 37.7%, 26.0%, 13.0%, and 23.3% for "Qi deficiency of both spleen and lung (脾肺氣虛)", "Yin deficiency of both liver and kidney (肝腎陰虛)", "Blood deficiency of both heart and spleen (心脾血虛)" and "Yang deficiency of both spleen and kidney (脾腎陽虛)", while Sasang constitutional distribution was 59.7%, 22.1% and 18.2% Soeumin, Taeumin and Soyangin, respectively. The fatigue severity was notably different between CFS ($63.7{\pm}12.1$) or ICF ($52.2{\pm}15.3$) according to the Chalder fatigue scale (10-point scale for eleven questions). There was statistical significance regarding symptom differentiation and Sasang constitution (p < 0.05). Conclusions: In the process of traditional Korean medicine-based development of therapeutics for patients with chronic fatigue or related conditions, this report can serve as reference data.
Purpose: The purpose of this study was to identify the relationship between fatigue, and self-efficacy in patients with lung cancer. Method: The data was collected from January 21th to April 8th 2001. The study subjects were recruited from K hospital in Pusan, Korea. Their fatigue was measured using the 22-item Revised Piper Fatigue Scale developed by Piper et al. (1998) and translated by the investigators, and self-efficacy was measured using the 10-item General Self-efficacy Questionnaire developed by Lee, Schwarzer & Jerusalem. The data were analyzed by SPSS 10.0 program using frequency, percentage, mean and standard deviation, t-test, ANOVA, Post-hoc test (Scheffe's test), and Pearson Correlation Coefficients. Result: 1) The mean fatigue score was $118.48{\pm}33.02$ (range: 22-220). The scores for sub-dimension were $35.40{\pm}10.06$ in behavior/severity, $25.98{\pm}9.06$ in affective score, $27.88{\pm}10.06$ in sensory score, and $29.22{\pm}8.27$ in cognitive/mood. The mean self-efficacy score was $28.80{\pm}5.85$. 2). There were significant differences in the fatigue of patients with lung cancer on income per month (F=4.651, p= .014), 'present pain' (F=2.601, p= .012), 'change of weight' (F=5.911, p= .005), by general characteristics. 3) There were significant differences in the self-efficacy of patients with lung cancer on 'religion' (F=3.732, p= .031), 'employment status' (F=5.525, p= .003), 'past therapy' (F=2.869, p= .034), by general characteristics 4) There was a significant negative correlation between fatigue and self-efficacy (r=- .528, p= .000). Conclusion: Patients with lung cancer experience fatigue. Increased fatigue is associated with decreased self-efficacy. Nurses must provide patients with nursing care for the less occurrence of fatigue and interventions to manage self-efficacy for them.
Purpose: The purpose of this study was to identify the relationship of fatigue and quality of sleep in patients with cancer. Method: The data was collected from January to February 2001. Study objects were recruited K university hospital in Busan, Korea. Their fatigue was measured using the Revised Piper Fatigue Scale developed by Piper et. al(1998), and quality of sleep was measured using Quality of Sleep Questionare by Oh et. al(1998). Result: 1) The fatigue score was mean $114.80{\pm}34.88$(range: 22-220). The sub dimension that showed behavior/severity score at $33.70{\pm}13.89$, affective score at $24.23{\pm}3.33$, sensory score at $27.74{\pm}12.51$, and cognitive/mood score at $29.11{\pm}3.71$. And sleep quality score was mean $37.32{\pm}8.18$. 2) There was a significant difference in religion(F=4.157, P= .008), present therapy(F=2.536, P= .043), past therapy(F=6.625, P= .000), major caregiver(F=3.133, P= .028), and change of weight(F=7.965, P=.006), according to general characteristics in the fatigue in patients with cancer. 3) There was a significant difference in present pain(t=-2.103, P= .037) and change of weight(F=5.484, P=.005), according to general characteristics in the sleep quality in patients with cancer. 4) There was a significant negative correlation between fatigue and quality of sleep(r=- .340, P= .000). Conclusion: Patients with cancer experience in fatigue. Increase in fatigue are associated with decreases in quality of sleep. Nurses must provide patients with nursing care about the occurrence of fatigue and interventions to deal with sleep disturbance.
