42. Long-term corrosion behavior and biocompatibility testing of titanium-based alloy covered with nano-crystalline hydroxyapatiteMonica Popa, Cora Vasilescu, Silviu Iulian Drob, Julija Hmeljak, Andrej Cör, Jose Maria Calderon Moreno, 2015, izvirni znanstveni članek Opis: In this paper, we applied on the surface of the new Ti%20Nb%10Zr%5Ta alloy nano-crystalline hydroxyapatite (HA) coating by the method of the chemical deposition in a solution supersaturated with Ca2+ and inline image ions. The composition and crystallinity of the obtained coating was determined by X-ray diffraction, micro-Raman, infrared, and energy dispersive X-ray spectroscopies and its morphology and porosity by scanning electron microscopy. The coating long-term corrosion behavior for 3000 soaking hours in simulated human fluids (Ringer's solutions of different pH values) was studied by cyclic potentiodynamic and linear polarization, electrochemical impedance spectroscopy and monitoring of the open circuit potentials and corresponding open circuit potential gradient due to the pH non-uniformity of the biofluid. Also, the coating biocompatibility was performed by cells (human osteoblast % HOS and human immortalized pulmonary fibroblast % Wi-38) adhesion and proliferation testing in the HA coated bioalloy extract compared to respective effects of the un-coated bioalloy extract. The initial HA nano-coating promoted the deposition of new HA layers, thickening itself and showing its ability to induce the formation of this main inorganic component of the human bone, therefore denoting bioactivity of the HA nano-coated alloy.

43. Students' assessment and self-assessment of nursing clinical faculty competencies : important feedback in clinical education?Robert Lovrić, Nada Prlić, Davor Zec, Silvija Pušeljić, Boštjan Žvanut, 2015, izvirni znanstveni članek Opis: The students' assessment of clinical faculty competencies and the faculty members' self-assessment can provide important information about nursing clinical education. The aim of this study was to identify the differences between the students' assessment of the clinical faculty member's competencies and the faculty member's self-assessment. These differences can reveal interesting insights relevant for improving clinical practice.

50. Improving the use of e-learning in health care curricula : presentation of best practicesPatrik Pucer, Boštjan Žvanut, Damjan Vavpotič, 2016, izvirni znanstveni članek Opis: E-learning is nowadays included in different health care curricula. However, this learning and teaching approach is still relatively underused in the health care study programmes. Hence, the goal of this article is to present three e-learning best practices in health care, which were validated in our previous projects/studies.First best practice, e-learning practice contents for the development of critical thinking, presents the approach which resulted in significant (p<0.001) raise in the number of discussion posts (+12.2%) for which the opinions and conclusions of the participants were justified with valid arguments. Furthermore, also the survey results showed that students achieve critical thinking skills with these contents. Second best practice, inclusion of the health care students in the development of e-contents, also resulted as a valid approach for improving the use of e-learning in health care curricula, which was confirmed by the expert opinion and e-contents final users. Finally, third best practice, our approach for evaluation and comparison of e-learning and traditional pedagogical elements value by health care students and teachers, was confirmed in the interview with the management as a valid approach that helps the management to identify whether previous elearning initiatives and activities were successful. Best practices, presented in this paper, represent the evidence that the use of modern information and communication technologies should be considered in the future as a serious requisite in health care study programmes. The broader community interested in the e-learning initiative should prepare a list of similar best practices, validate its effectiveness and prepare guidelines for their optimal implementation..
