Abstract The mixing uniformity of the double drum recycling mixing plant has an important effect on the quality of recycled asphalt mixture. The mixing uniformity of the double drum recycling mixing plant not only depends on the axial installation angle of the blade, the radial installation angle of the blade, the phase angle of the stirring arm, the inclination angle of the drum, and the rotation speed of the drum, but also on the interaction between these factors. In order to further clarify the relationship between the mixing uniformity and the above factors, the significance and interaction of influencing factors of mixing uniformity were studied based on EDEM and response surface methodology (RSM). The result shows that the factors affecting the mixing uniformity of the aggregates are significantly different when the aggregate size is different. Therefore, when studying the mixing uniformity of a mixing plant, it is not comprehensive to conduct research on a certain factor in a single-sided manner. Instead, the main factors and the interaction between the factors should be considered comprehensively.

The study aims at identifying the factors influencing the disposition effect acting on equity investors and further identifying the relationship between the influencing factors. The study aims at conducting a complete analysis of the influencing factors along with measuring their impact on disposition effect using Social Network Analysis (SNA).The factors affecting disposition effect on investors were identified through the literature review. Experts’ opinions were sought for determining the relationship among the factors and finally, the importance of those factors was analyzed using Social Network Analysis (SNA). It was found that social trust, investor emotion are the two most important factors affecting the other factors of disposition effect and consequently disposition effect finally. Besides, mental accounting; regret aversion, trading intensity, trading volume, and portfolio performance strongly influence the effect of disposition on investors because of their higher in-degree and out-degree. Therefore, the policymakers need to impart training to the investors to understand the mechanism of the stock market so that they can evaluate their standing in the stock market which, in the long run, will be reflected in their investment behavior.

Motility is a very important parameter to determine the quality of semen. Spermatozoa motility assessment can be done manually (subjectively) or with CASA. The superiority of motility assessment using CASA compared to manually is more objective, accurate, fast, efficient and able to provide detailed motility of spermatozoa. However, in implementation, assessments with CASA produce varied data. So far, there has not been a spermatozoa motility standard with CASA, except by minimizing variations in the factors that influence the results of analysis with CASA. The purpose of this paper is to describe factors that affecting spermatozoa motility analysis using CASA to reach optimal motility analysis. Some influencing factors include: CASA settings, semen diluent, spermatozoa concentration, chamber, analyst, sample preparation and analysis time. Recommendation standard motility assessments using CASA include: experienced and consistent analysts, sample preparation properly (mixing, pipeting and sampling), spermatozoa concentration of 20 million / ml, consistent in chamber type (conditioned 37°C), semen diluents and CASA settings (frame rate of 60 Hz and frame per field 30) and fast implementation of analysis (<2 minutes).

Research On Application

Because of the heating limitation of old pavement and the restriction of climate, the quality of hot in-place recycled pavement was different to control. The warm m,ix asphalt technology was introduced to improve the heterogeneity and compactness of the hot in-place recycled pavement and decrease its construction temperature. The compaction characteristics of warm in-place recycled asphalt mixture were analyzed and its molding temperature was determined through the Marshall test. The pavement performance of warm in-place recycled asphalt mixture was analyzed whose results indicated that the introduction of warm mix asphalt technology was able to improve the compactness, the high temperature stability and water stability of hot in-place recycled asphalt mixture and reduce the influence of environment over its construction quality. A warm in-place recycled engineering of Shian expressway was introduced to verify the feasibility of warm in-place recycling technology which demonstrated that the warm in-place recycling technology was able to improve the heterogeneity and compaction quality of the recycled pavement and weaken the environmental pollution.

Purpose: The study aimed to investigate the relationship between moral distress and the quality of nursing care.Methods: This cross-sectional correlation study included nurses working at oncology nursing units of two secondary general hospitals in Seoul and Gyeonggi-do, Korea. A total of 207 nurses participated. Moral distress was measured by the Moral Distress Scale-Revised Nurse Questionnaire and quality of nursing care was evaluated by the Quality of Oncology Nursing Care Scale. Data were collected from October 5 to 31, 2018. Data analysis included descriptive statistics, independent t-test, ANOVA, Pearson’s correlation coefficient and multiple regression analysis.Results: The quality of oncology nursing care showed a negative correlation with moral distress (r=-.19, <i>p</i>=.007). The factors affecting the quality of oncology nursing care were religion (β=-.22, <i>p</i>=.001), clinical experience in oncology units (β=.27, <i>p</i>=.007), and moral distress (β=-.16, <i>p</i>=.018). Moral distress showed a statistically significant predictive power of 13% in the regression model (F=8.70, <i>p</i>=<.001).Conclusion: The findings of this study suggest that management of moral distress is important to increase the quality of oncology nursing care.

Abstract Purpose To investigate the status quo and relationship between self-management efficacy and quality of life (QOL) of patients with breast cancer undergoing endocrine therapy, and to explore the influencing factors of QOL. Methods The convenience sampling method was used to select 240 patients who received endocrine therapy after breast cancer surgery in the First Hospital of China Medical University, the self-designed general data questionnaire, self-management efficacy questionnaire for breast cancer patients with endocrine therapy and quality of life scale for breast cancer patients were used to investigate. The frequency, percentage, mean ± standard deviation were used to describe patients' self-management efficacy and quality of life. Pearson correlation analysis was used to analyze the relationship between self-management efficacy and quality of life, and univariate analysis and multiple stepwise regression were used to analyze the influencing factors of QOL. Results The scores of self-management efficacy and QOL of patients with breast cancer endocrine therapy were 125.21 ± 25.57 and 153.33 ± 19.31 respectively, which were at the middle level; self-management efficacy was significantly positively correlated with quality of life ( p < 0.01 ) ; multiple stepwise regression results showed that self-management efficacy, the number of physical symptoms, monthly family income and recurrence and metastasis were the influencing factors of QOL. Conclusion The self-management efficacy of endocrine therapy was positively correlated with QOL in breast cancer patients. The higher the self-management efficacy of endocrine therapy, the better QOL in breast cancer patients. Self-management efficacy is the main factor affecting the quality of life of breast cancer patients undergoing endocrine therapy. Improving the level of self-management efficacy can improve their quality of life.
