Purpose: The purpose of this study was to identify the effect of Tai Chi exercise program on pain, fatigue, depression, self-efficacy, and quality of life in elderly women. Method: A quasi-experimental design, a nonequivalent control group pretest-posttest was the method of this study. Elderly women who agreed to participate in the study were conveniently placed into an experimental group (n=33) or an control group (n=34). The experimental group participated in Tai Chi exercise program, which was held for 60 minutes per session and 3 times a week for 8 weeks. Tai Chi exercise program consisted of a 10 minute warm-up, a 45 minute main session, and a 5 minute cooling down. In order to evaluate the effects of Tai Chi exercise program, pain, fatigue, depression, self-efficacy, and quality of life were measured with a questionnaire. The data were analyzed using Chi-square test, Fisher's exact test, t- test, and ANCOVA by SPSS WIN 13.0 program. Results: Compared with the control group, the experimental group reported higher level of quality of life (F=7.67, p=.007) and self-efficacy (F=20.9, p=.000) and lower level of pain (F=10.93, p= .002), fatigue (F=6.28, p=.015), and depression (F=10.02, p=.002). Conclusions: This study suggests that Tai Chi exercise program may be one of the effective nursing interventions for elderly women.

In this paper, we present a joint quality control system to be able to accurately control the relative picture quality among the video programs in terms of PSNR. The joint quality control system allows variable bit rate (VBR) for each video program to maintain the pre-determined relative picture quality among the aggregated video programs while keeping a constant sum of the bit rates for all programs to be transmitted over a single constant bit rate (CBR) channel. This is achieved by simultaneous controlling the video encoders to generate VBR video streams at the central controller. Furthermore we also suggest buffer regulation method based on the analysis of the constraints imposed by sender/receiver buffer sizes and total transmission rate. Through various simulation results, it is found that our quality control systems guarantee that the video buffers do not overflow and underflow and the quality control errors do not exceed 0.1 ㏈.

Purpose: This study was to show the effects of a Physical activity promotion program with tele-coaching on physical fitness (grip strength, static and dynamic equilibrium) and quality of life in the frail elderly. Methods: Data were collected from May 30 to October 19, 2008. The subjects were divided into 2 groups, an experimental group (n=27) and a control group (n=26). The experimental group participated in the Physical activity promotion program, and the control group did not participate in any Physical activity promotion program. Results: The results of this study supported the hypothesis that "the experimental group will have higher physical fitness (right grip strength, left grip strength and static equilibrium except dynamic equilibrium) and quality of life than the control group." Conclusion: Physical activity promotion programs with tele-coaching are strongly recommended as health promotion for the frail elderly.

Purpose: This study was conducted to develop a respiratory nursing program using recorder playing for patients with asthma and to determine the effects of the program. Method: Participants were 26 patients with asthma (experimental group: 13, control group: 13). The experimental group participated in the respiratory nursing program for six months from April, to October, 2007. Content included playing a recorder, group education about asthma, and educational messages including cellular phone messages. The control group received usual care during the six months. Results: In this research the respiratory nursing program using recorders was developed in 3 stages: initial stage, advanced stage, and wrap up stage. Compared to the control group, fatigue status in the experimental group improved significantly as well as level of forced expiratory volume in 1 second. However significant differences were found in sleep status, mood, or quality of life. Conclusions: These results suggest that this respiratory nursing program for symptom management of patients with asthma led to improvements in self care activity. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented over a transition period.

Purpose: This study was conducted to identify the effects of a self-monitoring rehabilitation program based on the Bandura's self-efficacy theory on the activities of daily living (ADL), 6-minute walking distances, self-efficacy and quality of life (QoL) among stroke patients after three to six months. Methods: The participants consisted of 29 patients in the experiment group and 28 patients in the control group who admitted at rehabilitation specific hospital. Self-monitoring program developed by the researcher lasted twice a week for 8 weeks from August to September, 2013. Results: ANCOVA showed that all of dependent variables of this study, ADL and 6-minute walking distances as a physical function, self-efficacy and QoL for intervention group were higher than those for control group(p<.001). Conclusion: The self-monitoring rehabilitation program based on the self-efficacy theory was found to be effective in improving physical function, self-efficacy and QoL for early post-stroke patients. Early rehabilitation program for stroke patients was recommended to consider the self-monitoring of current physical and psychosocial status as a strategy of self-management.
