PURPOSE
The present study was intended to measure fatigue symptoms according to the quality of sleep among nurses working for an university hospital and to reveal its related factors. METHODS: The self-administered questionnaires were given to 397 nurses employed in an university hospital located in Daejeon City during the period from June 1st to July 31st, 2007. RESULTS: The group with higher quality of sleep accounted for 78.1% of all the subjects and the one with lower quality, 21.9%. According to qualities of sleep, the fatigue symptom was determined to be significantly higher in the group with lower quality of sleep than its counterpart. On adjustment for quality of sleep, the level of fatigue symptom was significantly higher in the groups, than in each respective counterparts, who don't take regular exercises, who have few leisure time, who have lower level of subjective health status, who range> or = 1 and < 10 years in job careers, who work in shifts, who reported that it is hard to get physical burden of work, who are satisfied with the job, who find themselves unfit to the job, who are considering quitting the job, who have higher job demand, who have lower job control, who have higher level of supervisor support, who have type A behavior pattern. CONCLUSION: The study results may explain that the fatigue symptom of nurses is highly associated with the quality of sleep independently of other variables and also with job-related characteristics independently of the sleep quality. In conclusion, to reduce the fatigue symptom of nurses, strategic efforts should be directed for programs to improve the quality of sleep and a proper job analysis.

PURPOSE
This study examined the effect of a self-help management program which strengthens self-efficacy on the self-efficacy and the activities of daily living(ADL) in stroke patients. METHODS: A quasi-experimental nonequivalent control group, pre and post design was used. The subjects consisted of 47 stroke patients. Twenty-six patients were assigned to the experimental group and 21 patients were assigned to the control group. The self-help management program by strengthen self-efficacy and general hospital care were carried out on the experimental group. General hospital care was performed on the control group. The data was collected before and 5 weeks after the program. All subjects were questioned about the self-efficacy and ADL before and after the program. RESULTS: The scores of the self-efficacy and ADL in the experimental group were higher than those in the control group. CONCLUSION: The self-help management program by strengthen self-efficacy is effective in increasing the self-efficacy and ADL. Therefore this program may be a useful intervention to increase the ADL in stroke patients.

PURPOSE
The study aimed to apply Tai Chi exercise to patients with coronary artery disease for 6 months, and to examine changes on body composition, physical strength, and cardiovascular risks. METHODS: Applying a quasi experimental design with a nonequivalent control group, 90 subjects with cardiovascular disease were recruited at C university hospital. For 6 months, 44 subjects performed Tai Chi exercise once a week and daily home exercise, while 46 subjects did not. Body composition was assessed by body mass index, % body fat, and waist-hip ratio; physical strength by balance, mobility, flexibility, grip strength, and back muscle strength; and cardiovascular risk checklist for fixed and modifiable risk factors. Data were analyzed by SPSS/WIN program with ANCOVA to consider group differences at the pretest. RESULTS: The subjects were 66 years old in average. In 6 months, Tai Chi group improved significantly in balance, mobility, and flexibility with decreased modifiable cardiovascular risks after adjusting for the pretest scores. CONCLUSION: Tai Chi exercise was safely applicable to individuals with coronary artery disease, and effective in some measures of physical strength and modifiable cardiovascular risks. It could be an alternative exercise for outpatient cardiac rehabilitation program in this population.

PURPOSE
This study was conducted to develop a simulation-based education course and to evaluate the results after the application for second year nursing students. METHODS: This study was a non-equivalent control pre-post design. Based on the clinical situation scenarios about patients with COPD and MI, a total of two simulation-based learning modules was developed. Pretest and posttest was conducted to evaluate the difference in critical thinking disposition, problem solving, and clinical competence between two groups of 102 students for the experimental group, 2007 and 90 students for the control group, 2006. The experimental group conducted a clinical performance evaluation in the final test, on December 10, 2007. RESULTS: In the experimental group, knowledge related to learning objectives was significantly increased and core intervention was performed almost exactly, but the same result was not observed in domains of analysis of laboratory test, and nursing education for patients. Self-evaluated clinical competence and problem solving level were significantly more improved in the experimental group than control group, but critical thinking disposition level wasn't. CONCLUSION: In conclusion, a simulation-based education course needs to utilize self-directed learning module like computer-based learning through web contents and MicroSim and video productions for improving nursing students' critical thinking.

PURPOSE
To examine the effects of power walking exercise on fatigue and overweight in college students with Taeumin constitution. METHODS: According to results of the constitution diagnosis (QSCC II), 58 students who were identified as Taeumin, whose BMI was over 23 were assigned to one of three groups. The power walking group walked fast at a speed of 7,000 steps per hour using a pedometer, and the walking group walked at a speed of 5,000 steps per hour. There was no treatment with control group. Each group's fatigue level, blood lipids and body composition before and after the experiment were compared and analyzed. RESULTS: Total fatigue and total cholesterol decreased significantly in the power walking group compared to the walking group and the control group. Weight decreased significantly in the power walking group compared to the control group, and percentage of body fat decreased significantly in both the power walking group and the walking group compared to the control group. CONCLUSION: When power walking exercise was used with overweight Taeumin students, fatigue, blood lipid, weight and percentage of body fat decreased significantly.

PURPOSE
The purpose of this study was to identify the factors affecting sleeping patterns among hospitalized elderly. METHODS: A descriptive correlational study was conducted. Participants were 121 hospitalized elderly in a hospital located in a county. A structured questionnaire was used for data collection. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and stepwise multiple regression. RESULTS: Almost a half of hospitalized elderly in this study suffer from sleep disturbances. As results of univariate analyses, physical symptoms, anxiety, depression, and environmental factors disturbed sleep among hospitalized elderly. However, the result of stepwise multiple regression analysis identified that anxiety and environmental factors were significant predictors of sleeping patterns for hospitalized elderly and these two factors accounted 32.5% of variance of sleeping patterns among hospitalized elderly. CONCLUSION: Sleep assessment should be conducted on admission to identify sleep difficulties and thereby to improve quality of nursing care. Nurses and other health care personnels should make efforts to decrease anxiety and to eliminate environmental barriers of sleep among hospitalized elderly. Educational programs for nursing staff that offer information about sleep and sleep promoting interventions for the elderly patients are critical. Moreover, sleep promotion intervention program should be developed, applied and evaluated.

PURPOSE
This study was intended for the enhancement of the elderly's quality of life helping them overcome their physiological changes about aging and reinforcing their vitality. METHODS: An nonequivalent control group post-test design was used for the study. The methods to perform the abdominal respiration exercise and to blow the pan-flute were demonstrated to 31 experimental subjects and 36 control subjects. The eight-week 30 minute daily home respiration exercise recipes were prescribed to the subjects. Mobile spirometers were used to measure FVC, FEV1, FFV1 / FVC, SaO2, breathing discomfort. Daily life satisfaction scores were recorded. Music therapy accompanied the eight-week respiration program. A post-test was performed in the same manner as the pre-test. The gathered data were analysed by SPSS/WIN program. RESULTS: 1) The pulmonary function and daily life satisfaction were significantly improved in the experimental group. 2) Both the experimental and control groups did not show significant differences in SaO2. 3) The breathing discomfort was significantly reduced in the experimental group. CONCLUSION: The respiration exercise program for the elderly through the pan-flute improves the respiration activity of the elderly and enhances their daily life satisfaction scores. Therefore, this program produces effects in enhancing the quality of life for the elderly.

PURPOSE
This study was conducted to compare the recovery state of 6 month between s-ICH and s-SAH patients. The patients' recovery state was measured with 2 dimensions: functional and cognitive. METHODS: Non-experimental prospective design was adopted by including 108 hemorrhagic stroke patients(s-ICH: 52 vs s-SAH: 56) admitted to Intensive Care Unit of one university hospital. RESULTS: The study results showed that overall functional recovery state of s-SAH patients was better than that of s-ICH patients, and s-SAH patients also showed better recovery states in all of the sub-dimensions of functional recovery, such as feeding, grooming, and toileting, than those of s-ICH in 6 month. On the contrary, the study results showed that overall cognitive recovery states of 6 month between two groups were not significantly different. However, according to the results comparing the sub-dimensions of cognitive recovery, s-SAH patients' recovery states on attention, communication and memory were significantly better than those of s-ICH patients, while recovery states on problem solving, safety behavior, and social behavior between 2 groups were not significantly different. CONCLUSION: From the study results, it was noted that s-SAH patients showed better recovery states in cognitive dimension as well as in functional dimension compared with s-ICH patients.

CONCLUSION: In this study, the tailored exercise program was effective and safe for the elderly, and resulted in improving physical and psychological health status in the elderly. This demonstrated that the tailored group exercises program on the basis of the subject's fitness, played an essential role in maintaining and improving the health.

PURPOSE
The aim of this study was to construct leisure physical activity model of middle-aged women in urban area. METHODS: Data were gathered by self-report questionnaire from 211 women aged between 41 and 59 years in urban community. The data were analyzed using the SPSS/WIN 10.0 program and the model was constructed using the LISREL 8.54 program. RESULTS: Variables that have direct effects on leisure physical activity were health state, past leisure physical activity, social support, self-efficacy, and affect. Perceived leisure state and behavioral leisure attitude also influenced leisure physical activity in an indirect way. Perceived leisure state had a direct effect on self-efficacy. Behavioral leisure attitude, past leisure physical activity, and experience of exercise effect had significantly direct effects on affect CONCLUSION: It will provide basic information for developing strategies of programs to enhance leisure physical activity of middle-aged women in urban area.

PURPOSE
this study was to develop and test the structural model that explains husband and wife compatibility and family health of married middle-aged. A hypothetical model explaining husband and wife compatibility and family health based on literature reviews. There were three theoretical variables and twelve observed variables in hypothetical model. METHODS: Data collection was carried out May through July 2005. Data were collected by self-reporting questionnaires from 854 married middle-aged who lived in Seoul, Busan, Daegu, Kyungnam, Kyungpook. Collected data was analyzed using SPSS/WIN 12.0 for descriptive statistics, Pearson Correlation coefficient, and Kolmogorov-Smirnov analysis. RESULTS: LISREL program was used to find the best fit normal which assumes causal relationship among variables. This model was to be good fitting and parsimonious to measure husband and wife compatibility and family health of married middle-aged. CONCLUSION: Differentiation of self and husband and wife compatibility predicted level of family health. Therefore, a family health improvement program needs to include these two variables.

PURPOSE
This study was conducted to develop and test an explanatory model on functional capacity in patients with chronic obstructive pulmonary disease using path analysis. METHODS: Data were collected from 149 chronic obstructive pulmonary disease patients using 6-minute walk test, measurement of oxygen saturation, pulmonary function test, and self-reported questionnaires from June to October, 2005. The collected data were analyzed using SPSS/WIN 12.0 program and AMOS/WIN 4.0 program. RESULTS: The overall fitness indices of modified model were good( chi-square = 14.324, p = .281 GFI = .981, RMSEA = .006, AGFI = .944, NFI = .927, NNFI = .999, CFI = .999, PNFI = .613, chi-square /df = 1.194). Functional capacity was influenced directly by age(beta = -.304, p = .000), dyspnea(beta = -.278, p = .000), self-efficacy(beta = .240, p = .000), social support(beta = .175, p = .004), pulmonary function(beta = .169, p = .008), and oxygen saturation(beta = .099, p = .048). These variables explained 39.3% in functional capacity. CONCLUSION: The findings of this study suggest that comprehensive nursing interventions should focus on decreasing dyspnea and increasing self-efficacy, social support, and oxygen saturation. In this perspective, pulmonary rehabilitation would be an effective strategy for improving functional capacity in patients with chronic obstructive pulmonary disease.

PURPOSE
The purpose of this study was to identify the effect of meridian acupressure on constipation in bed-ridden aged inpatients. METHODS: The research design was a non-synchronized non-equivalent control group pretestposttest design. The subjects consisted of 28 bed-ridden aged inpatients. Meridian acupressure was administered to the experimental group at 30 minutes before breakfast every morning for two weeks. Each meridian was pressured for 10 seconds, 10 times. The frequency of defecation and stool form were examined every day. The data was analyzed by the chi-square-test, Fisher's exact test, t-test and repeated measures ANOVA. RESULTS: The experimental group given Meridian Acupressure had a higher frequency of defecation(F = 59.372, p = .000) and normal stool(F = 46.046, p = .000) than the control group. CONCLUSION: The results suggest that Meridian Acupressure was an effective method for the relief of constipation for bed-ridden aged inpatients. A follow -up research is needed to validate that other patients with constipation can use the Meridian Acupressure as a non-invasive nursing intervention instead of a laxative or enema.
