Purpose: The purpose of the study is to investigate the degree of fatigue and its related factors in patients with breast cancer. Method: The subjects of this study consisted of 62 breast cancer patients receiving chemotherapy. The Revised Piper Fatigue Scale, Disruption of Usual Activity Scale, Linear Analogue Self Assessment Scale and Self-Care Diary Scale were employed to measure fatigue, disruption of usual activity, mood state and physical symptom respectively. Collected data were analyzed using SPSS-PC to obtain summary statistics for the descriptive analysis, Pearson Correlation, and Stepwise Multiple Regression. Result: The results are as follows. 1. The mean score of the degree of fatigue was 4.82 points indicating moderate level. 2. The mean score of the degree of disruption of usual activity, mood state and physical symptom were 2.66, 5.00, and 4.69 points. 3. Fatigue of the subjects was significantly correlated with disruption of usual activity(r=.517, p<.01), mood state(r=.420, p<.01) and physical symptom(r=.463, p<.01). 4. With the result of stepwise multiple regression, disruption of usual activity, mood state and physical symptom being the three variables which could explain fatigue by 39.1%. The results of this study suggest that comprehensive intervention strategy for fatigue should be developed to maintain quality of life during and following chemotherapy considering these factors.

Purpose: This study was conducted in order to define factors influencing learned helplessness in undergraduates. Independent variables including external entrapment, internal entrapment, social support, trait anger, state anger, and anger expression were used to predict learned helplessness. Methods: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. A total of 241 undergraduates recruited from September to November 2012 were included in the study. Results: Four factors of learned helplessness were founded to show significant correlation with external entrapment, internal entrapment, social support, trait anger, state anger and anger expression. Stepwise multiple regression analysis showed that 64% of the variance in learned helplessness was significantly accounted for by internal entrapment, social support and anger expression. Conclusion: This study showed that perceived entrapment and social support are important predictors of learned helplessness. Therefore, in order to reduce learned helplessness in undergraduates, it is necessary to design an intervention program with strategies to help in coping with and reducing perceived entrapments.

During compression molding of fibre-reinforced thermoplastics, the two main problems such as the fibre-matrix separation and the fibre orientation are produced by the flow state. As the molded product tends to be nonhomogeneous and anisotropic due to the separation and the orientation, it is necessary to clarify these in relation to the molding process variables and the fibre structure (fibre entanglement). If the entanglement of fibre structure is strong, the separation increases and the orientation is not easily aligned. Namely, these are inseparably related to each other. The correlation between the separation and the orientation have to be clarified for designing the fibre structure. In this paper, the degree of nonhomogeneity which is a measure of the separation is obtained using one-dimensional rectangular shaped part compression molding. And the orientation function is defined and measured by the image processing using soft X-rayed photograph and image scanner. Correlation between the degree of nonhomogeneity and the orientation function is discussed.

This paper considers the case of pricing discretely-sampled variance swaps under the class of equity-interest rate hybridization. Our modeling framework consists of the equity which follows the dynamics of the Heston stochastic volatility model, and the stochastic interest rate is driven by the Cox-Ingersoll-Ross (CIR) process with full correlation structure imposed among the state variables. This full correlation structure possesses the limitation to have fully analytical pricing formula for hybrid models of variance swaps, due to the non-affinity property embedded in the model itself. We address this issue by obtaining an efficient semi-closed form pricing formula of variance swaps for an approximation of the hybrid model via the derivation of characteristic functions. Subsequently, we implement numerical experiments to evaluate the accuracy of our pricing formula. Our findings confirm that the impact of the correlation between the underlying and the interest rate is significant for pricing discretely-sampled variance swaps.
