Purpose: The purpose of the study was to examine the relationships among pain belief, perceived social support, coping strategies, and quality of life of people with noncongenital spinal cord injury and to identify factors influencing quality of life. Methods: A correlational predictive design was used. The data were collected from 197 people with noncongenital spinal cord injury with questionnaires in 2012 in Korea. The data were analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using SPSS/WIN 18.0. Results: Pain belief, perceived social support, and coping strategies were correlated significantly with the quality of life. As a result of stepwise multiple regression analysis, pain belief, perceived social support, coping strategies, damaged area, and time since injury were discovered to account for 59.1% variance of the quality of life. The variable that most affected the quality of life was pain belief followed by perceived social support and coping strategies. Conclusion: The results of the study clearly demonstrate the importance of pain control, social support, and coping skills in order to improve quality of life among people with noncongenital spinal cord injury.

Purpose : This study investigated the correlation between social support and older people's quality of life. Methods : We conducted a questionnaire survey with 350 older participants and analyzed 320 completed surveys. The collected data were analyzed using SPSS 25.0 for Windows. The general characteristics of the participants and quality of life subdomains were analyzed using descriptive statistics and frequency analyses. Furthermore, the differences between the subdomains of social support and quality of life were analyzed using independent t-tests and a one-way ANOVA. Post-hoc tests were performed using the Scheffé test. A significance level of α=.05 was used to verify statistical significance. Results : Upon examining the sub-domain level of social support and considering general characteristics, it was found that older age correlates with increased dependency among patients with associated diseases (p<.05). Similarly, an investigation into participants' quality of life at the subdomain level, considering general characteristics, revealed higher correspondence to lower quality of life (p<.05). Differences emerged between social support and quality of life among older individuals, with a negative correlation observed between the two (p<.05). Conclusion : This study suggests the importance of actively supporting older people with chronic diseases who experience emotional and psychological instability. It advocates for promoting the use of various services, including visiting medical services, convalescent care, and assistance, to meet their needs effectively.

A hybrid kernel function of support vector machine is proposed to improve the classification performance of power quality disturbances. The kernel function mathematical model of support vector machine directly affects the classification performance. Different types of kernel functions have different generalization ability and learning ability. The single kernel function cannot have better ability both in learning and generalization. To overcome this problem, we propose a hybrid kernel function that is composed of two single kernel functions to improve both the ability in generation and learning. In simulations, we respectively used the single and multiple power quality disturbances to test classification performance of support vector machine algorithm with the proposed hybrid kernel function. Compared with other support vector machine algorithms, the improved support vector machine algorithm has better performance for the classification of power quality signals with single and multiple disturbances.

This study was designed to identify the relationship between perceived pain, family support and quality of life in patients with ankylosing spondylitis. The purpose of this study was to contribute to the theoretical understanding of the relationship of these three variables and eventually to more effective adaptation of patients to their situation. The subjects for this study were the 68 patients who had been diagnosed with ankylosing spondylitis and registered as out-patients in the Rheumatism Center of one university hospital in Seoul. The data were collected during the period from October 10, 1997 to December 20, 1997, Pain was measured using the perceived pain scale(VAS : Visual Analog Scale)developed by Calm(1993), family support using the scale developed by Kang Hyun Suk (1985) and Quality of Life using the scale developed by Ro Yoo Ja(1988). The data were analyzed by descriptive statistics, Frequencies, Pearson correlation coefficient, using the SPSS program. The results of this can be summarized as followings. 1. The mean perceived pain score was 5. 13 with a range of 2 to 10. 2. The mean perceived family support score was 41.08$\pm$5.34 with a range of 20 to 50. 3. The mean perceived quality of life score was 134.07$\pm$19.82 with a range of 83 to 176. 4. Significant statistical difference was found between family support and quality of life (r=.331, p<0.001). A significant negative statistical difference was found between the family support and quality of life and pain(r=-.250, p<0.05, r=-.460, p<0.001). 5. General characteristics related to pain were exercise (t=4.72, p<0.0006). 6. General characteristics related to family support were age(F=2.65, p<0.0246), educational level (F=2.84, p<0.0282) and exercise (t=3.24, p<0.0452). 7. General characteristics related to quality of life were educational level (F=3.03, p<0.0392) and exercise (t=3.12, p<0.0465). It was found that the higher the level perceived pain, the lower the degree of perceived family support and the quality of life. It was also found that the higher the degree of perceived family support, the higher the degree of perceived quality of life. Accordingly, the conclusions from this study are that reduction of pain is achieved through the family support. Therefore, it is proposed that family support is an appropriate nursing intervention to improve the quality of life of patients with ankylosing spondylitis.
