Social support and meaning of life in women with breast cancer

BACKGROUND: Social support is known as an affection-oriented coping mechanism when a person is involved with cancer. Therefore, this study was conducted to investigate the relationship between family social support and the meaning of life in women with breast cancer.METHODS: In this cross-sectional study, 84 women with a mean age of 60 (SD = 5.7) years with breast cancer who were admitted to a teaching hospital participated. Data were collected using social support and meaning of life questionnaires. After collecting the completed questionnaires and entering the data into the computer, the analysis was performed using SPSS software and using t-test, ANOVA, and Pearson correlation test at a significant level of 0.01.RESULTS: The mean score of their social support was 39.35 ± 9.51, respectively and the meaning of life was 29.5 ± 7.49. ANOVA results indicated that the social support score and meaning of life had no significant relationship with any of the demographic variables. Also, the findings suggest that there is a statistically significant correlation between social support and the meaning of life (r = 0.773, P < 0.001).CONCLUSION: It is proposed to increase the level of social support from the family to help improve the meaning of life in cancer patients

The role of motivation in achieving management goals

One of the major responsibilities of managers in an organization is to identify potential capacities of the personnel and to bring about conditions for their growth and realization of these capacities which in turn, serves the basic goal of promoting productivity. In other words, gaining knowledge about motivational factors for improving performance and productivity of the organization is of great importance. Also, such this knowledge can greatly help to improve the application of human resources in organizations, prevent employees’ resistance against change, reduce limitations in the output, and prevent conflict among personnel, a process which consequently results in a profitable organization. Motivation is about human life and realization of goals. Human beings live and work happily and hopefully when they feel alive and perceive a meaningful relationship between their work and life

Experimental evaluation of steel fiber effect on mechanical properties of steel fiber-reinforced cement matrix

This paper investigates the possibility of combining steel fibers with different weight percentages along with their functions in increasing compressive strength, indirect tensile strength and bending strength. In this study, two types of steel fibers, hooked and crimped, have been employed in the preparation of samples. These fibers have a length to diameter ratio of 30 mm and 50 mm (L/D=30 and L/D=50). Further, the combination of these fibers caused a reduction in concrete flow and reduced its efficiency. The combination of these fibers caused considerable increase of concrete bending strength compared to fibreless and single-fiber type concretes. In this research, tensile strength and bending strength of samples with 1.5%, 2% and 2.5% fibers were investigated in which the tensile strength and bending strength of all samples increased. However, there were very considerable increases in tensile strength and bending strength of samples made with hybrid crimped fibers. The results indicated that steel fibers did not have much impact on concrete compressive strength

Association Analysis for Some Biochemical Traits in Wild Relatives of Wheat under Drought Stress Conditions

In the present study, we estimated genetic diversity and population structure in 186 accessions of Triticum and Aegilops species using 24 simple sequence repeat markers (SSR). Furthermore, an association analysis was performed for antioxidant activities, including guaiacol peroxidase (GPX), ascorbate peroxidase (APX), peroxidase (POX), catalase (CAT), and dry matter (DM) under two control and drought stress conditions. Our findings showed that drought treatment significantly decreased DM, whereas activities of all antioxidant enzymes were increased compared to the control conditions. The results of correlation analysis indicated that, under drought stress conditions, all biochemical traits had a positive and significant association with each other and with dry matter. In the molecular section, the results of the analysis of molecular variance (AMOVA) indicated that the molecular variation within species is more than within them. The dendrogram obtained by cluster analysis showed that grouping the investigated accessions was in accordance with their genomic constitutions. The results of association analysis revealed 8 and 9 significant marker–trait associations (MTA) under control and drought stress conditions, respectively. Among identified MTAs, two associations were simultaneously found in both growing conditions. Moreover, several SSR markers were associated with multiple traits across both conditions. In conclusion, our results could provide worthwhile information regarding marker-assisted selection for the activity of antioxidant enzymes in future breeding programs
