Toxic metal bearing effluents can cause severe environmental contamination; thus metal removal by adsorption is a vital situation. In this study, apple pulp carbon was tested as low-cost adsorbent for the copper(II) and cobalt(II) adsorption studies. 25 full factorial experimental design was utilized to optimize the effects of pH, adsorbent dosage, initial metal ion concentration, contact time and temperature. ANOVA, F-test and Student’s t-test showed that Cu(II) and Co(II) adsorption is slightly temperature and contact time dependent but markedly increases with solution pH and adsorbent dosage. Although the initial Cu(II) concentration had a negative effect on removal efficiency, the initial Co(II) concentration had a positive effect. The suggested optimum conditions for 90.49% Cu(II) and 65.11% Co(II) removal were: pH 5, the adsorbent dosage = 0.4 g/50 mL, the initial metal ion concentration = 10 and 20 mg/L, temperature = 40 and 20 °C, contact time = 60 and 120 min, respectively. pH was found as significant within a 95% confidence level for both Cu(II) and Co(II) removal. Additionally, main effects of adsorbent dosage and initial concentration, the interaction effect of pH × initial concentration were also found as significant for Cu(II) removal. In conclusion, apple pulp carbon could be successfully applied for the removal of heavy metals because of its low-cost and abundance.

Background: Once limited with face-to face courses, health education has now moved into the web environment after new developments in information technology This study was carried out in order to give training to the university academic and administrative female staff who have difficulty in attending health education planned for specific times and places. The web-supported training focuses on healthy diet, the importance of physical activity, damage of smoking and stress management. Materials and Methods: The study was carried out in Sakarya University between the years 2012-2013 as a descriptive and quasi experimental study. The sample consisted of 30 participants who agreed to take part in the survey, filled in the forms and completed the whole training. The data were collected via a "Personel Information Form", "Health Promotion Life-Style Profile (HPLSP)", and "Multiple Choice Questionnaire (MCQ). Results: There was a statistically significant difference between the total points from "Health Promotion Life-Style Profile" and the total points from the sub-scale after and before the training (t=3.63, p=0.001). When the points from the multiple choice questionnaire after and before training were compared, it was seen that the average points were higher after the training (t=8.57, p<0.001). Conclusions: It was found that web-supported health training has a positive effect on the healthy living behaviour of female staff working at a Turkish university and on their knowledge of health promotion.

Background: The aim of this study was to determine the health beliefs and knowledge about breast self examination (BSE) and the actual BSE habits of female university nursing students. Materials and Methods: The study sample recruited 189 nursing students who agreed to participate in the study. Descriptive statistics, the Mann-Whitney U test, one way ANOVA test, t test and Pearson correlation analysis were used to analyse the data. Results: 83.1% of nursing students had knowledge about breast cancer (BC) and BSE in the study. BSE was practiced by 70.4% of nursing students; 21.8% of them performed BSE regularly. A fear of developing BC was an incentive for 85% of nursing students to practice BSE. The confidence subscale scores in the third and fourth years of students' university education were higher, and the barrier subscale score in these same years was lower than their first years of study. Perception of benefit of nursing students experiencing breast-related discomfort exerted a positive effect. Nursing students with lower perception of barriesr performed BSE regularly. In conclusion, nursing students' years of university study, breast cancer knowledge, history of breast cancer in family, and BSE practice status were factors affecting their health beliefs. Conclusions: These study results indicate the importance of developing education and training programs which educate not only nursing students but all women about breast cancer, its symptoms, the importance of early diagnosis and of regular BSE.

Background: Studies of quality of life (QoL) of oncological patients is carried out using questionnaires approved in many international clinical studies. The European Organization for Research and Treatment of Cancer EORTC QLQ-C30 (Quality of Life Questionnary-Core 30) and its special brain cancer module EORTC QLQ-BN20 are widely used in the world neurooncologic practice. They are available in more than 80 official versions of 30 languages of the world. Previously we used the official versions in Russian, which often causes difficulty in understanding for native Kazakh language speakers, who comprise more than 60% of our respondents. This was the reason for creating a version of Kazakh language. Therefore, in 2014 for the first time the process of adaptation of questionnaires to the Kazakh language was initiated. Materials and Methods: The translation process of questionnaires to Kazakh language was held in accordance with the requirements of the European Organization for Research and Treatment of Cancer EORTC on QoL and consisted of the following stages: preparation - translation - pilot testing - approval. The official permission of authors and "Guideline on translation" was obtained which was developed by the working group of the EORTC on QoL. The pilot testing of EORTC QLQ-C30 and QLQ-BN20 questionnaires was conducted on the basis of the Department of Central Nervous System Pathology of the "National Centre for Neurosurgery" in patients with malignant tumors of the central nervous system. Results: The official versions of the EORTC QLQ-C30 and QLQ-BN20 questionnaires in Kazakh language were introduced and adapted in practical neurosurgical operations in Kazakhstan. Conclusions: The approved versions of the questionnaires in Kazakh language are now available for mainstream use on the official website EORTC.com. The versions of these questionnaires can be used in domestic cohort studies and clinical practice in the Republic of Kazakhstan. The use of these tools for assessing QoL will help professionals in the planning of individual treatment strategies and selection of the necessary therapy.

Background: Breast cancer (BC) is one of the most common cancer affecting women worldwide. Although a great deal of progress has been made in the health sciences, early diagnosis, and increasing community awareness, breast cancer remains a life-threatening illness. In order to reduce this threat, breast cancer screening needs to be implemented in all communities where possible. Objective: The purpose of this study was to examine health beliefs, attitudes and behaviors about breast cancer and breast self-examination of Turkish women. Methods: Data were collected from a sample of 656 women, using an adapted Turkish version of Champion's Health Belief Model Scale (CHBMS), between January and May 2011, in Ordu province of Turkey. Results: The results showed that 67.7% of women had knowledge about and 55.8% performed BSE, however 60.6% of those who indicated they practiced BSE reported they did so at irregular intervals. CHBMS subscales scores of women according to women's age, education level, occupation, family income and education level of the women's mothers, family history of breast cancer, friend and an acquaintance with breast cancer, knowledge about breast cancer, BSE and mammography were significantly different. Conclusion: Knowledge of women about the risks and benefits of early detection of breast cancer positively affect their health beliefs, attitudes, and behaviors. Health care professionals can develop effective breast health programs and can help women to gain good health behavior and to maintain health.
