Effect of anxiety and depression on self-care agency and quality of life in hospitalized patients with chronic obstructive pulmonary disease: a questionnaire survey.

Chronic obstructive pulmonary disease (COPD) affects the lives of individuals in a number of ways; it causes an increase in the need for help and support and a decline in self-care agency and quality of life. This research has been conducted in patients with COPD hospitalized in the Pulmonary Department of Erzincan State Hospital in the eastern Turkey to examine the effect of anxiety and depression on self-care agency and quality of life (n = 135). The results showed that 69.6% and 85.6% of the patients were at risk for anxiety and depression, respectively, and that the mean scores of self-care agency and quality of life decreased as the mean scores of anxiety and depression increased. It was also established that the mean score of the quality of life increased as the mean score of self-care agency went up. It could be concluded that the majority of the patients are at risk for anxiety and depression and that presence of anxiety or depression has a negative effect on the self-care agency and the quality of life. The recognition and treatment of depression and anxiety in patients with COPD provide significant improvements in self-care agency and quality of life of patients.

Application of advanced oxidation processes to different industrial wastewaters.

This study examines the application of photochemical and non-photochemical advanced oxidation processes on the treatment of textile, Kraft bleaching, photoprocessing, and pharmaceutical wastewaters. Effects of reaction conditions on the treatment efficiency of industrial wastewater have been investigated. The results were evaluated in terms of biodegradability enhancement. The results indicated depending upon the composition of wastewater and applied pretreatment all applied AOPs had an ability to increase the biodegradability of studied wastewaters.
