Öğe Does Traffic Safety Climate Perception of Drivers Differ Depending on Their Traffic System Resilience and Driving Skills Evaluation?(Springer International Publishing Ag, 2019) Guner, Gizem; Tumer, Ece; Ozturk, Ibrahim; Oz, BaharRoad traffic accidents are one of the most important public health problems in Turkey and all over the world. Traffic system involves many agents from a micro level, such as drivers, to a macro level, such as traffic climate. Traffic system resilience and driving skills are crucial factors that determine the road traffic accidents and their outcomes; in addition to being related to the development of sustainable and safer road traffic system. In this study, it is aimed to investigate group differences derived from traffic system resilience and driving skills with respect to traffic safety climate. For this purpose, 323 drivers (177 female, 146 male), between the ages of 19 and 57 (M = 28.56, SD = 8.96), participated in the study. Participants filled out a questionnaire including demographic information form, Driving Skills Inventory, Traffic Climate Scale, and Traffic System Resilience Scale adapted to traffic settings by the researchers. The data were analyzed by using t-test to be able to compare groups. According to the results, traffic systems that are perceived to be high in terms of resilience were also perceived to be less externally demanding and more functional. In this study, traffic system resilience was evaluated by the perception of drivers and the relationships between traffic system resilience, driving skills, and traffic safety climate were evidenced for the first time in the literature. The implication of the results is discussed by focusing on the ways the findings could be used to improve traffic safety.Öğe Effect of the type of cardiopulmonary bypass pump flow on postoperative cognitive function in patients undergoing isolated coronary artery surgery(Turkish Soc Cardiology, 2016) Ozturk, Selen; Sacar, Mustafa; Baltalarli, Ahmet; Ozturk, IbrahimObjective: Pulsatile flow, generated by a pump during cardiopulmonary bypass, has been accepted as more physiological in coronary arterybypass grafting surgery (CABG). Therefore, we aimed to investigate the effects of pulsatile and nonpulsatile flow on postoperative cognitive function and to review relationship with the biomarkers S100 beta and neuron-specific enolase (NSE). Methods: Patients who underwent isolated CABG were included this prospective, randomized, double-blind study, which was performed between March 2010 and December 2010. Patients were divided into two groups: pulsatile (Group I, n=20) and nonpulsatile (Group II, n=20) flow. Blood samples were collected 1 day before surgery and in the sixth postoperative hour for the analysis of S100 beta and NSE. In addition, Mini-Mental State Examination (MMSE) was performed during preoperative period and on third postoperative day. Outcomes were determination of effects of pump flow type on cognitive function and relationships with concentrations of S100 beta and NSE. Results: Forty patients were included. No differences were observed between the groups with respect to complications, mortality, S100 beta (Group I: 1.9 +/- 0.2 mu/L; Group II: 2.0 +/- 0.2 mu/L), NSE (Group I: 12.5 +/- 0.8 mu/L; Group II: 12.4 +/- 0.7 mu/L), MMSE scores [Group I: 25 (23-27); Group II: 25 (23-27)], and postoperative cognitive dysfunction (POCD) (p>0.05). No correlation was observed between MMSE scores and concentrations of S100 beta (r=-0.032) and NSE (r=-0.423) (p>0.05). Conclusion: There was no difference between types of pump flow for POCD and no relationship between cognitive dysfunction and S100 beta and NSE concentrations. Pump flow type does not affect NSE concentrations.Öğe Ermenek Mine Accident in Turkey: The Root Causes of a Disaster(Springer International Publishing Ag, 2019) Ozturk, Ibrahim; Mevsim, Ridvan; Kinik, AycaMining accidents are one of the critical safety concerns all over the world. From the general point of safety, it is important to identify human factors, especially violations, and other types of barriers with respect to the occurrence of an accident. Root Cause Analysis helps to identify the mechanism behind accidents and develop future countermeasures for prevention. In the current analysis, Ermenek Mine Accident in Turkey was evaluated by using Root Cause Analysis Tool Kit and Manchester Patient Safety Framework (MaPSaF). Safety issues were structured by using Five Whys, Fishbone Diagram, and Barrier Analysis and safety culture were evaluated by using some of the dimensions of MaPSaF. Main factors were structured by using Five Whys, Barrier Analysis, and Manchester Safety Framework. According to these main factors, fishbone diagram was constructed. In general, natural, personnel, general policy in mining industry, and management issues in mining industry were determined as main four deficiencies affecting the occurrence and consequences of the accident. These main four factors were detailed in the fishbone diagram. The results indicated the importance of including different agents in the process of mining and working in cooperation to develop necessary policies and actions. Some methodological and practical suggestions were made for safety related issues. It is important to state policies related to basin in mining by considering both economic factors and safety factors. Moreover, reports related to safety issues should be more detailed by considering individual and organizational safety culture factors.Öğe INVESTIGATING THE RELATIONSHIP BETWEEN DRIVER BEHAVIORS AND PEDESTRIAN BEHAVIORS(Bmj Publishing Group, 2018) Ozturk, Ibrahim; Oz, Bahar[Anstract Not Available]
