Itoh의 역원 계산방식에 사용되는 곱셈의 회수는 GF(2?)상에서 nb(m-1)+ ω(m-1)-2로 알려져 있다. 최근에 Itoh의 방식을 다소 개선한 빠른 역원 계산방식이 발표되었는데 그 근거를 확률적인 방법과 실험을 통하여 주장했다. 본고에서는 구체적인 계산을 통하여 곱셈회수를 구하였다.

R&D process has special characteristics such as uncertainty, dynamic, and uniqueness. There have been many researches on workflow modeling methods, but they have mainly focused on general business processes which are relatively repetitive and predictable. So, the conventional workflow modeling methods and related systems are limited to managing the characteristics of R&D process. We propose a new workflow modeling method to accommodate the R&D characteristics. The present study integrates two process flavors - business process and science process, based on control-flow perspective for predictable workflow and data-flow perspective for problem solving workflow respectively. The construction procedure of problem solving workflow is also provided and the benefits of the proposed method are demonstrated through an example.

Purpose: There has been much debate over the participation of patients in decision making regarding treatment, and an increasing emphasis has been placed on patient autonomy. This study was done to identify factors associated with older patients' participation in cancer surgery decision making. Methods: The research was a cross-sectional, descriptive design using questionnaires. The participants were 150 patients with cancer who had embarked on surgical treatment in two tertiary hospitals. Data were analyzed using descriptive statistics, t-test, ANOVA and multiple regression with the SPSS statistics 19.0 program. Results: There were statistically significant differences in participation in decision making regarding surgery by gender, age, and spouse. Stepwise multiple regression analysis for participation in decision making regarding surgery revealed that the most powerful predictor was intelligibility about the surgery. Intelligibility about the surgery and gender explained 33.0% of the variance. Conclusion: The results indicate a need to improve intelligibility about the surgery with these participants. The findings also suggest that consideration be given to characteristics of gender, age, and spouse in developing strategies for enhancing intelligibility about the surgery and developing programs to promote participation in decision making regarding surgery among older patients with cancer.
