A probabilistic analysis model. one of reliability analysis methods introducing the concept of variables, was developed to investigate the uncertainty of dominant factors influencing the degree of consolidation in the radial consolidation theories. Based on the developed probabilistic analysis model, sensitivity study of those factors was performed to find their trends of affecting the degree of consolidation in the vertical drain method. Various radial consolidation theories, proposed by Barron(1948), Hansbo(1979), Yoshikuni(1979) and Onoue(1988), were used for this parametric study with the influencing factors such as size of smear zone, reduction ratio of permeability in the smear zone, discharge capacity, permeability for horizontal flow and coefficient of consolidation for horizontal flow. As results of this sensitivity study, for the given consolidation theory, contribution of each factor to the degree of consolidation was figure out and compared to each other. For the given value of each factor, the sensitivity to the degree of consolidation in the various theories was evaluated and their applicability and limitations were assessed.

Purpose: The purpose of this study is to examine the factors influencing symptom experience in patients with liver cirrhosis(LC). Method: A descriptive correlational study design was used. A convenience sample of 129 subjects was recruited from the gastroenterology department at two university hospitals in Seoul, Korea. Symptom experience in LC was measured with the instrument developed by the researcher based on Theory of Unpleasant Symptoms(Lenz et al, 1995) and the Child-Pugh Score, the Korean version of Profile of Mood States, and the Family Support Questionnaire were used to identify the factors influencing symptom experience. Results: The mean score of symptom experience was relatively low(M=41.67, SD= 24.71). Among individual symptoms, fatigue had the highest score in all dimensions. Fatigue, abdominal distension and/or peripheral edema, muscle cramps, dry mouth, and change in appearance were explored as symptoms needing management. In the regression analysis, symptom experience was found to be influenced significantly by anxiety/depression($R^2=.418$, p=.000) and the severity of LC(Child-Pugh Score)($R^2=.125$, p=.000). These variables explained 54.3% of the variance in symptom experience(F=63.607. p=.000). Conclusion: It suggests that nurses need to take into consideration psychological factor as well as physiological factor in symptom management for patients with LC.

Research collaboration is an important strategy to improve research output, and virtual academic communities (VACs) have become an important platform to collaborate on. This paper reveals the influencing factors of researchers' collaboration intention in VACs from two attributes: individual, and inter-members. On the basis of the Social Cognitive Theory, Social Exchange Theory, social network theory, and Five-Factor Model, this paper constructed a model demonstrating the influencing factors of VACs researchers' collaboration intention. A self-administered questionnaire was employed on members of four VACs in China to collect data; subsequently, 558 usable responses were analyzed using structural equation modeling. The result showed that openness, conscientiousness, reciprocity, trust, and the social network characteristic had a significant influence on the collaboration intention of researchers in VACs, while self-efficacy, agreeableness, extroversion, neuroticism, and experience had no significant effects on the collaboration intention of researchers in VACs. This model plays a positive role in promoting the research collaboration intention of Chinese VACs researchers and in guiding the construction of VAC platforms.

Objectives : This study aimed to identify the factors influencing insufficient physical activity in community-dwelling elderly individuals with dementia. Methods : Data were analyzed using a 2014 Survey of Living Conditions of Elderly Individuals. Metabolic Equivalent Task (MET) hours were calculated using self-reported weekly frequency, duration, and types of physical activities to measure the degree of physical activity. Results : Mean MET hours were $4.03{\pm}8.59$. Factors influencing insufficient physical activity included limitations in activities of daily living (ADL), lower frequency of social group participation and unsatisfactory relationships with friends or community. When demographic factors were adjusted, patients with ADL limitation had 11.2 times higher risks of insufficient physical activities than those without. Conclusions : Community-dwelling elderly with dementia performed low levels of physical activity. Further research is needed to develop strategies to encourage physical activity participation in this population.

Purpose: This study was conducted to identify factors influencing fundus examination to prevent diabetic retinopathy in diabetes patients to provide basic data to improve screening rates of fundus examinations. Methods: Raw data from the 6th Korea National Health and Nutrition Examination Survey, which is a cross-sectional and nationally representative survey, were used in this study. The subjects of the study were 1,029 adult diabetes patients over the age of 19 years who had been diagnosed with diabetes. The demographic characteristics, diabetes and disease-related characteristics and health behavior characteristics according to the fundus examinations were analyzed by the chi-squared test and logistic regression analyses were used to examine the factors influencing fundus examination. Results: A total of 333 patients underwent fundus examination at a screening rate of 32.2%. We identified factors influencing fundus examination in patients with diabetes as level of education, type of diabetes care, period of diabetes, and smoking. Conclusion: A multiple approach is required to raise the low screening rate of fundus examination, including specialized education for low-education groups. Moreover, nursing intervention should focus on subjects who do not engage in insulin and oral hypoglycemic agents and with diabetes for a long period.
