This study evaluated the effect of factors influencing the initial biofilm formation in drinking water distribution pipe by running experiments using a $2^{4-1}$ fractional factorial experimental design with a replicate. Important variables used for assessing biofilm formation included BDOC(biodegradable dissolved organic carbon), viable heterotrophic bacteria present in drinking water, water temperature, and shear stress at two levels each. Based on the statistical analysis of biofilm levels measured as attached HPC(heterotrophic plate count) and community-level assay, the main factors that have significant effects on biofilm formation were found to be viable heterotrophic bacteria and BDOC. Water temperature only exhibited significant effect on the levels of attached HPC, while shear stress was not a significant factor under given conditions. Moreover, the statistical analysis revealed that interactions between the important variables were not statistically significant at a 0.05 significance level.

Recently, the valuation of patented technology has been greatly emphasized, and patent citation has been accepted as a very useful index of this technology. In this study, we performed correlation analyses between the patent citation counts and 17 explanatory variables of morphological, technological, and conceptual factors with a test dataset of U.S. patents in five subject fields. Seven variables having 5% or more standardized variances($r^2$) with patent citation counts were identified; number of pages, number of claims, reference-average-citation rate, patent increase/decrease rate, strength of bibliographic coupling, co-citation counts and document similarity. The result of the ANOVA test shows that the mean values of these variables vary among most subject fields.

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.
