INTRODUCTION|This research was conducted in order to detect the relevance between 'burnout' and 'ethical climate perceptions' of nursing staff in a university hospital.¤METHODS|This cross-sectional ...correlation study was carried out in a medium size university hospital between March 2019 and July 2019.Participants of this descriptive correlational study were 241 nurses working in a university hospital. Socio-demographic data form, Ethical Climate Questionnaire and Maslach Burnout Inventory were used to gather data for determining correlations.¤RESULTS|It was detected that the study group had an average level of ethical climate perception. Work-place and willingness to prefer profession were partially effective on ethical climate perceptions of the staff nurses. A partial correlation was found between ethical climate and burnout.¤DISCUSSION AND CONCLUSION|Our study group has an average level of ethical climate perception. Our results support the hypothesis that there may be a relationship between ethical climate perceptions and burnout each of which is known to deteriorate nursing care quality and patient safety. We suggest preventive interventions such as training, setting ethics based organizational rules or creating supportive practice environments in terms of ethics to generate better ethical climate in the institutions.¤
INTRODUCTION: This study was conducted to identify the professional self-concept and the related factors among student nurses studying at a nursing faculty and to investigate the relationship between ...moral sensitivity and the professional self-concept. METHODS: This was a descriptive and correlational study carried out on 381 nursing students. The Student Information Form, Professional Self-Concept Scale for the Student Nurses, and the Moral Sensitivity Questionnaire were employed as the study tools. Descriptive and inferential statistics were used to analyze the data. RESULTS: A weak and reverse relationship was found between the professional self-concept and moral sensitivity of nursing students. A decrease in moral sensitivity score was correlated with a high professional self-concept. DISCUSSION AND CONCLUSION: There was a correlation between a decrease in moral sensitivity score and a high professional self-concept.
This study aims to determine perceived stress levels and coping with humor in cancer patients receiving chemotherapy. This descriptive study was conducted in a single center in Turkey and involved a ...total of 135 patients who had been diagnosed with cancer. The patients receiving chemotherapy had high levels of perceived stress and their use of humor as a coping strategy in stressful situations was below average. The perceived stress scale score was statistically significantly associated with age, employment status, presence of chronic disease, frequency of chemotherapy sessions and receipt of radiotherapy (p <0.05). The coping humor scale score was statistically significantly associated with age, education, economic status, previous hospitalization and time since diagnosis (p <0.05). Increasing the awareness of patients about humor and the use of humor starting from the time of cancer diagnosis can positively affect treatment and follow-up.
In calcium aluminate cement (CAC) systems the hydration process is different than portland cement (PC) systems. The hydration products of CAC are subjected to conversion depending on temperature, ...moisture, water-cement ratio, cement content, etc. Consequently, strength of CAC system can be seriously reduced. However, presence of other inorganic binders or additives may alter the hydration process and improve various properties of CAC based composites.
The objective of this study is to investigate the temperature effect on the behaviour of CAC based composite binders. Throughout this research, several combinations of CAC-PC, CAC-gypsum, CAC-lime, CAC-ground granulated blast furnace slag (CAC-GGBFS) were studied. These CAC based composite binders were subjected to seven different curing regimes and their strength developments were investigated up to 210 days. In addition, the mechanism of strength development was examined by XRD analyses performed at 28 and 210 days. Finally, some empirical relationships between strength-time-curing temperatures were formulated.
Experimental results revealed that the increase in ambient temperature resulted in an increase in the rate of conversion, thereby causing drastic strength reduction, particularly in pure CAC mix. It has been observed that inclusion of small amount of PC, lime, and gypsum in CAC did not induce conversion-free CAC binary systems, rather they resulted in faster conversion by enabling rapid formation of stable C3AH6 instead of metastable, high strength inducing CAH10 and C2AH8. On the other hand, in CAC-GGBFS mixes, the formation of stable straetlingite (C2ASH8) instead of calcium aluminate hydrates hindered the conversion reactions. Therefore, CAC-GGBFS mixes, where GGBFS ratio was over 40%, did not exhibit strength loss due to conversion reactions that occurred in pure CAC systems.
