Objectives: This study is conducted to identify the effects of the activity program for preventing dementia against depression, cognitive function, and quality of life for the elderly. Methods: A non-equivalent control group with pretest-posttest design was used on 50 elderly who were assigned to the experimental and control group (25 for each group). Results: Cognitive function was significantly different between the two groups of the pretest and posttest (Z=4.217, p<.001). There were significant differences between the two groups of the pretest and posttest (Z=-2.324, p=.020) for the quality of life on the EQ-5D index. Conclusions: These findings confirmed that the activity program for preventing dementia was effective for improving cognitive functions and quality of life for the elderly. Therefore, it is further encouraged to perform the activity programs for preventing dementia within other community health posts and community centers. It is necessary to study the emotional supports from community health posts in the future.

Purpose: This study was to examine the effects of a Self-management program on physical function and quality of life of women with knee osteoarthritis. Method: The participants for this study, who had knee osteoarthritis, were recruited from an arthritis clinic, at a university hospital located in S city, Korea between February 16, 2004 and June IS, 2004. Seventeen subjects in the control group received no intervention and 18 subjects in for experimental group received an individual Self-management program. The self-management program consisted of dietary education and home-based exercise; walking and resistance exercise. The subjects performed this program 5 times per week during 8 weeks and recorded a diary for diet and exercise. In order to verify the effects of the Self-management program, physical function and Quality of life as a dependent variable were measured at three points in time: before, week4 and week8 after the interventions. Result: There were significant increases on physical function (F=5.08, p=.002) and significant interaction effects (F=7.42, p=.002) in the intervention group over the three measurement points in time. In addition, there were significant increases on quality of life (F=8.08, p=.002) and significant interaction effects (F=4.89, p=.016) in the intervention group over the three measurement points in time. Conclusion: This study revealed that a Self-management program can be used as an efficient nursing intervention for women with knee osteoarthritis.

This paper presents a selective duality control system to control relative picture quality among the video programs in terms of Peak Signal-to-Noise Ratio (PSNR) . The selective quality control system allows variable bit rate (VBR) for each video program to maintain the pre-determitted relative picture Quality among aggregated video programs while keeping a constant bit rate for alt programs to be transmitted over a single constant bit rate (CBR) channel. Thus is achieved by simultaneous controlling the video encoders to generate VBR video streams at the central controller. furthermore, we also suggest a buffer regulation method based on the analysis of the constraints Imposed by sender/receiver buffer sizes and the total transmission rate. Through various simulation results, it is found that the proposed quality control system guarantees that the video buffers neither overflow nor underflow and the quality control errors do not exceed 0.1 dB.

Purpose: This study was to determine the effect of a smartphone video educational program on educational satisfaction of patients in rehabilitation units at a university hospital. Methods: The subjects of this study were 60 stroke patients recruited and divided into two groups; experimental group (n=30) and control group (n=30). Subjects in the experimental group and control group conducted conventional physical and occupational therapy. In addition, only the experimental group provided smartphone video information for a total of 15 sessions. The video consisted of five episodes (10 minutes each) viewed a total of 15 times (for each video three times). The outcome was assessed by educational satisfaction. Result: After inervention, both groups revealed significant increased awareness of prevention of infection educational satisfaction and prevention from falling educational satisfaction and exercise program educational satisfaction. However, the experimental group was more effective than the control group relative to heightened awareness of increasing prevention of infection prevention from falling and exercise program. Conclusion: We suggest that a smartphone video educational program may be effective in improving awareness of the prevention of infection, prevention from falling, and exercise program educational satisfaction. Therefore, video-based information is beneficial for such patients. Further studies are needed for better understanding of the effectiveness of a smartphone video educational program in rehabilitation units at a university hospital.

Purpose: This study aimed to develop an integrated health promotion program for cancer survivors residing in the community based on the shared care model, and evaluate its effectiveness. Methods: A quasi-experimental trial was conducted. The participants consisted of 35 cancer survivors with completed intensive cancer therapy at the cancer hospital. The intervention group (n=20) and the control group (n=15) were recruited from among a district home cancer patient registrations. The intervention group participated in an integrated health promotion program based on the MAPP (Mobilizing for Action through Planning and Partnership) development process. The program consisted of physical, psycho-social and body image units. The participants were assessed before the program, and immediately after the program. Data were collected between July 1 and September 2, 2018 using FACT-G quality of life (QOL), distress thermometer (DT), and resilience. The data were analyzed by performing a χ2 test, Fisher's exact test, Mann-Whitney test, and ranked ANCOVA using SPSS. Results: The intervention group reported a higher QOL overall and significantly higher social/family well-being than the control group. Distress was significantly lower in intervention group than in the control group. Resilience had no significant difference between the two groups. Conclusion: These findings indicate that the integrated health promotion program base on the shared care model and MAPP development process could be effective intervention for improving social/family well-being and the QOL, and reducing distress of cancer survivors at home. Community health center nurses need to provide intervention to support self-care competency for cancer survivors' comprehensive care with physical, psycho-social, and body image to help them adjust their life to a moderate risk group in the community.

The aim of this study was to investigate the quality properties of beef jerky replaced salt with soy sauce, red pepper paste, and soybean paste. The quality properties of beef jerky including final water activity ($a_w$), moisture content, pH, color, shear force, total plate counts, thiobarbituric acid reactive substance (TBARS) values, and sensory evaluations were investigated. The sliced beef samples were marinated in salt (control), soy sauce (T1), red pepper paste (T2), and soybean paste (T3) for 24 h and then dried at $70^{\circ}C$ for 6-8 h. The water activity of finished beef jerky varied from 0.72 to 0.70. The water activity for control and T1 samples decreased more rapidly as drying proceeded up to 6 h. The samples with salt replacement showed a lower pH and lightness than the control (p<0.05). The T1 sample showed a significant decrease in total plate counts after 21 d of storage (p<0.05). The TBARS for all treatments increased with storage days (p<0.05). The TBARS were significantly lower in T2 and T3 samples compared to control and T1 until 21 d of storage (p<0.05). The samples with salt replacement showed a lower intensity of saltiness than the control. Sensory evaluations found that the replaced soy sauce of beef jerky samples had better overall acceptability scores than the other treatment samples. It was concluded that replacing salt with soy sauce can delay lipid oxidation and enhance the sensory acceptance of beef jerkies.

Purpose: This study was to examine the effects of sleep promoting program on sleep and the immune response in the elderly with insomnia. Methods: The study was designed as a quasi-experimental, nonequivalent control group pre-post test design. Thirty two elders who suffered from insomnia (16 experimental and 16 control subjects) were selected among the elders who had been enrolled in two churches. The subjects in the experimental group participated in a sleep promoting program which was composed of sleep hygiene education and progressive muscle relaxation for 4 weeks. Data were analyzed using the SPSS/WIN. Results: The experimental group showed higher sleep score than that of the control group (t=7.86, p=.00). The experimental group showed higher sleep satisfaction score than that of the control group (t=7.61, p=.00). The sleep promoting program was not effective in enhancing immune response. Conclusion: The sleep promoting program increased the sleep score, sleep-satisfaction score and B cell in immune response of elderly people suffering from insomnia. Therefore, sleep promoting program can be applied as an effective nursing intervention to promote sleep quality and sleep satisfaction.

This study was designed to determine the outcomes of the team-based cardiac rehabilitation programs for patients with Ischemic Heart Disease(IHD) on their level of health behavior performance, anxiety, and quality of life. A total of 19 in-patients with IHD who have had PTCA treatment at G.Hospital in Inchon were selected as subject to data collection from 1 May 1998 to 30 Oct. 1998. The experimental group, consisting of 11 patients participated in the Hospital's cardiac rehabilitation program was compared with the non-rehabilitation control group of 8 patients. The experimental group has been trained on the cardiac rehabliltation programfor 120-150minute during hospitalization by a team consisted of four specialists, those are cardiologist, head nurse, dietian, and the author. Also individual follow-up training and interview were performed for the members of experimental group at their every visit to the Hospital after discharge. For all subjects, scores on health behavior performance, anxiety, and quality of life were collected two days and 12 weeks after PTCA treatment by questionnaire. The collected data were analyzed with the SPSS. The results of this study were summarized as follows : 1) The experimental group shows significant increase in health behavior performance score compared to the control group(-2.27, p=.022). 2) There was no significant difference between two group's anxiety scores (-.24, p= .803) and quality of life scores(-1.86, p= .061). 3) The correlation between health behavior performance and anxiety ( .07, p= .771), and that between health behavior performance and quality of life( .12, p= .621) respectively were not significant statistically. But the correlation between anxiety and quality of life were significant reversely ( .49, p= .032).
