Öğe DIFFICULTIES EXPERIENCED BY NURSING STUDENTS DURING COMMUNICATION WITH DISABLED CHILDREN AND EVALUATION OF THEIR TENDENCY FOR STIGMATIZATION(Springer, 2016) Ozturk, O.; Onan, N.; Kar, G.[No abstract available]Öğe Effect of homovalent Bi/Ga substitution on propagations of flaws, dislocations and crack in Bi-2212 superconducting ceramics: Evaluation of new operable slip systems with substitution(Elsevier Sci Ltd, 2019) Turkoz, M. B.; Zalaoglu, Y.; Turgay, T.; Ozturk, O.; Yildirim, G.This study defines a strong methodology between the mechanical performance behaviors and formation possible operable slip systems in the crystal structure of Bi-2212 superconducting phase with trivalent Bi/G substitution with the aid of Vickers hardness tests exerted at various indentation load intervals 0.245 N-2.940 N. It is found that the mechanical performance behaviors improve regularly with the increment in the trivalent Bi Ga partial substitution level up to the value of x = 0.05 due to the formation of new operable slip system. Namely, the optimum gallium (Ga) impurities serve as the strain fields and associated forces for the interaction of dislocations within the different orientations with each other to impose the surface residual compressive stresses orienting favorably the superconducting grains. Thus, the propagation of dislocations, flaws and cracks divert in the crystal structure. On this basis, the presence of optimum Ga impurity in the Bi-2212 crystal syster strengthens the mechanical strength, critical stress, resistance to the plastic deformation, stiffness and durabilit nature. Moreover, the experimental results advance in-depth understanding of fundamental links between th porosity and Young's moduli of elasticity founded on the impurity level and applied test loads. It is observed that in case of the optimum level of x = 0.05 the propagation of flaws, dislocations and cracks proceed along the transgranular regions instead of the intergranular regions as a consequence of improvement in the durabl tetragonal phase. On the other hand, the excess Ga content level in the polycrystalline Bi-2212 system results i the augmentation in the stress raisers, crack surface energy and crack-initiating flaws, activating the stress-induced phase transformation.Öğe Effects of breast cancer fatalism on breast cancer awareness among nursing students in Turkey(Asian Pacific Organization for Cancer Prevention, 2015) Kulakci, H.; Ayyildiz, T.K.; Yildirim, N.; Ozturk, O.; Topan, A.K.; Tasdemir, N.Background: Breast cancer is the most common cancer among women and leading cause of death worldwide, including in Turkey. High perceptions of cancer fatalism are associated with lower rates of participation in screening for breast cancer. This study was conducted to evaluate the effect of breast cancer fatalism and other factors on breast cancer awareness among nursing students in Turkey. Materials and Methods: This cross-sectional descriptive study was conducted at three universities in the Western Black Sea region. The sample was composed of 838 nursing students. Data were collected by Personal Information Form, Powe Fatalism Inventory (PFI) and Champion's Health Belief Model Scale (CHBMS). Results: Breast cancer fatalism perception of the students was at a low level. It was determined that students' seriousness perception was moderate, health motivation, BSE benefits and BSE self-efficacy perceptions were high, and BSE barriers and sensitivity perceptions were low. In addition, it was determined that students awareness of breast cancer was affected by breast cancer fatalism, class level, family history of breast cancer, knowledge on BSE, source of information on BSE, frequency of BSE performing, having breast examination by a healthcare professional within the last year and their health beliefs. Conclusions: In promoting breast cancer early diagnosis behaviour, it is recommended to evaluate fatalism perceptions and health beliefs of the students and to arrange training programs for this purpose.Öğe EVALUATION OF AN ARTISTIC ACTIVITY PERFORMED TO DECREASE THE FEAR OF MEDICAL INTERVENTIONS IN SCHOOL AGE CHILDREN(Springer, 2016) Topan, A.; Ozturk, O.[No abstract available]Öğe EVALUATION OF INCLUSION OF HOSPITALIZED ADOLESCENTS' AUTONOMY IN NURSING PRACTICE(Springer, 2016) Ozturk, O.; Topan, A.[No abstract available]Öğe Evaluation of key mechanical design properties and mechanical characteristic features of advanced Bi-2212 ceramic materials with homovalent Bi/Ga partial replacement: Combination of experimental and theoretical approaches(Elsevier Sci Ltd, 2019) Turkoz, M. B.; Zalaoglu, Y.; Turgay, T.; Ozturk, O.; Akkurt, B.; Yildirim, G.This study models the variations in the key mechanical design properties and mechanical characteristic features of Ga substituted Bi-site Bi-2212 ceramics prepared within the different molar ratios of x = 0.000, 0.005, 0.010, 0.030, 0.050, 0.100 and 0.300 with the assistant of available theoretical approaches; namely, Meyer's law, proportional sample resistance, elastic/plastic deformation, modified proportional sample resistance model, Hays Kendall and indentation-induced cracking methods for the first time. The mechanical modeling parameters are gathered from the microhardness (Vickers) experimental tests performed at various applied loads interval 0.245 N-2.940 N. The results provide that the key mechanical design features improve systematically with the augmentation of trivalent Bi/Ga partial replacement level up to x = 0.05 due to the rapid decrement in the main structural problems; namely, the grain orientations, lattice strains, distortions, dislocations, grain boundary interaction/coupling problems, crack-initiating and crack-producing omnipresent flaws in the advanced Bi-2212 ceramic system. Accordingly, the optimum Ga inclusions strengthens the mechanical durability towards the applied stress due to the increased stabilization in the durable tetragonal phase. After the critical substitution amount of x = 0.05, the mechanism turns reversely, and the general mechanical characteristic features including the stiffness, mechanical durability and strength degrade remarkably. Additionally, the mechanical modeling results demonstrate that the Bi/Ga impurity leads to vary positively the quality of standard indentation size effect (ISE) feature until x = 0.05, beyond which the excess Ga additives damage seriously ISE feature of Bi-2212 inorganic compounds. Besides, the indentation-induced cracking (IIC) model is noticed as the best method to describe the true microhardness parameters of Bi/Ga substituted Bi-2212 compounds for the mechanical characterization.Öğe EVALUATION OF METHODS OF MOTHERS TO MAKE THEIR BABIES SLEEP AND LIFE QUALITY OF MOTHERS WHO HAVE 0-2 YEAR-OLD BABIES(Springer, 2016) Topan, A.; Ozturk, O.[No abstract available]Öğe EXAMINATION OF THE STATUS OF NURSES USING FAMILY-CENTERED CARE WHILE GIVING HEALTH CARE TO CHILDREN AT HOSPITALS(Springer, 2016) Ozturk, O.; Topan, A.; Karakaya, O.; Ciller, T.[No abstract available]Öğe Knowledge level of working and student nurses on cervical cancer and human papilloma virus vaccines(Asian Pacific Organization for Cancer Prevention, 2015) Topan, A.; Ozturk, O.; Eroglu, H.; Bahadir, O.; Harma, M.; Harma, M.I.Purpose: To determine knowledge levels of working and student nurses about cervical cancer and prophylactic cancer vaccines. Materials and Methods: This study was performed on 259 nursing students in the Department of Nursing and 137 nurses working in Health Research and Practice Center, approved to participate in the study between April-June 2012. The study was performed universally without selecting a sample. A questionnaire that was prepared for evaluating participants' knowledge and attitudes about human papilloma virus (HPV) vaccine was distributed to the nurses and data obtained from the forms were transferred to SPSS 15.00 program and statistically analyzed. Results: It was found that 54.8% of the student nurses were between 21-24 years old and 13.1% of working students were between 25-28 years old. When student nurses and working nurses were compared in terms of their knowledge about the causes of cervical cancer, their ideas about prevention from cervical cancer with HPV vaccine, their ideas about possible risks of HPV vaccine and conservation ratios of HPV vaccine, it was observed that there were no statistically significant differences (p>0.05). When student nurses and working nurses were compared in terms of the information-source about HPV, ways of HPV contamination, awareness about people who are susceptible to HPV contamination and age of HPV vaccination, it was determined that there was a statistically significant difference (p<0.05). Conclusions: It was found that all nurses had some knowledge about cervical cancer and HPV vaccine, but this was not sufficient. Therefore; it is recommended to use verbal, written and visual communication tools intensively in order to have topics on cervical cancer, early diagnosis and prevention in bachelor and master programs for nurses, to inform society about cervical cancer and HPV vaccine for public health and to teach precautions for its prevention.
