Data access characteristics can directly affect the efficiency of the system execution. This research is to design an accurate predictor by using historical memory access information, where highly accessible data can be migrated from low-speed storage (SSD/HHD) to high-speed memory (Memory/CPU Cache) in advance, thereby reducing data access latency and further improving overall performance. For this goal, we design a locally weighted linear regression prefetch scheme to cope with irregular access patterns in large graph processing applications for a DARM-PCM hybrid memory structure. By analyzing the testing result, the appropriate structural parameters can be selected, which greatly improves the cache prefetching performance, resulting in overall performance improvement.

The study aims to analyze the supply chain role of supervision, discipline, work climate, and organizational learning on the performance of community services at the public works. This study took a sample of employees through purposive sampling technique at the Public Works Office and Bina Marga in a regency in East Java. Data through questionnaire was collected through a 5-point Likert scale model. The results show that the application of employee discipline affects the performance of public services, with a contribution of 39.7%, meaning that discipline and organizational learning are implementation factors that have an effect on public service performance. In stepwise regression analysis, the supervisory factor has a correlation with service performance, but it is less relevant, while the work climate is not relevant as a predictor variable to improve public service performance. The study revealed the importance of the supply chain policy of implementing good and clean governance and the enactment of the performance appraisal of the government apparatus established through Good Corporate Governance of the state apparatus. The findings provide a basis to encourage the public sector performance to smooth every step of supply chain management of every government project work, especially in the field of public services.

Purpose: The purpose of this study was to identify variables influencing task performance of wound ostomy continence nurses (WOCN). Methods: Data were collected from 80 WOCN in Korea from September to October 2011 using a self-reported questionnaire. Variables consisted of task performance, empowerment, professional autonomy, job satisfaction and job-related variables. Data were analyzed by frequencies, t-test, one-way ANOVA, Pearson's correlation coefficient and stepwise multiple regression. Results: Professional autonomy was a major predictor of task performance of WOCN (F=37.37, p=<.001). Empowerment(F=33.10, p=.001) and completion of the professional education course for wound ostomy continence nursing WOCN(F=7.46, p=.008) were the other significant predictors of task performance. The regression model explained 45.3% of task performance. Conclusion: Professional autonomy, empowerment and completion of the professional education course contribute to task performance of WOCN. These findings have important implications for organizations hoping to achieve the maximum potential of WOCN's professional role. Therefore, strategies for reinforcement of professional autonomy, empowerment, and completion of professional education course are necessary for WOCN working in South Korea.

Purpose: This study was to identify the relationship between family support, self-efficacy and self-care performance in patients with chronic illness. Methods: The subjects were 100 in-and out-patients who were diagnosed with chronic illness at university hospital in Cheonan. The data analyzed using descriptive statistics, Pearson correlation coefficient and stepwise multiple regression with SPSS WIN 12.0. Results: The level of family support, self-efficacy and self-care performance were high. The family support in patients with chronic illness indicated a significant positive correlation to self-care performance but no significant correlation to self-efficacy. The self-efficacy in patients with chronic illness indicated a significant positive correlation to self-care performance. Family support and self-efficacy account for 24.4% of variance of the self-care performance. The most significant predictor which influenced self-care performance in patients with chronic illness was family support. Conclusion: The results of this study showed that family support and self-efficacy are very important variables in explaining the self-care performance. Therefore, these variables should be considered in nursing intervention development and education.

Purpose: The purpose of this study was to identify the learning style, learning efficacy, transfer of learning, and confidence in performance competence of Core Basic Nursing Skills (CBNS) and factors influencing confidence in performance competence of CBNS by nursing students. Methods: A descriptive study design was used. Participants were 148 nursing students. Data were analyzed using SPSS 20.0 for descriptive statistics, ANCOVA, correlation and regression. Results: Learning styles of the participants were assimilator 33.11%, accommodator 26.35%, diverger 23.65%, and converger 16.89%. Learning efficacy was significantly different according to learning styles, however, transfer of learning and confidence in performance competence of CBNS were not significantly different according to learning styles. Confidence in performance competence of CBNS positively correlated with transfer of learning and learning efficacy. Transfer of learning was a significant predictor of confidence in performance competence of CBNS. Conclusion: The findings of this study indicate that transfer of learning influences confidence in performance competence of CBNS. Thus, nursing faculty should develop educational strategies to enhance and improve transfer of learning, and development of effective confidence in performance competence of CBNS programs.
