In today?s world, all the higher education institutions across the world are trying to keep and improve their educational standards in order to respond to the ever-changing needs and expectations of all their stakeholders and to survive under great environmental pressure resulting from the stiff global and local competition. To this end, they need to plan, control and improve their own educational quality on a regular and continuous basis. However, if there is a considerable gap between the internationally agreed-upon quality standards and the quality offered within the institutional framework, it will be very difficult to claim objectively that the educational services provided are of the highest achievable quality. Thus, obtaining international quality accreditation is of crucial importance both in proving the educational quality offered institutionally and persuading all the stakeholders that the education provided is planned, monitored, evaluated and improved in line with the predefined and preset international quality standards. On the other hand, having an international quality accreditation as a higher education institution might not always guarantee a positive quality perception on the students? part, who are the actual consumers of the quality. The main purpose of this study is to analyze the relationship between the internationally accredited educational quality and the quality perception of the students studying at an English preparatory school of a foundation university in Turkey.

Marble excavation and processing are the most risky endeavors of the mining industry. Many precautions are taken to determine or prevent occupational accidents. Failure Mode and Effect Analysis (FMEA) is a risk assessment tool that can be easily applied to an occupational health and safety (OHS)-based improvement process. In this paper, marble processing techniques and failure mode effect analysis method were summarized, and a case study was performed in the marble processing plants of Afyonkarahisar, Turkey. The study tried to eliminate or improve primary risks by preparing an improvement program. The theoretical improvement was realized as 50.08% for the first period.

Moyamoya disease is an entity, which is caused by obstruction or stenosis in the area between the internal carotid artery, and anterior and middle cerebral arteries, identified angiographically, and does not have an exactly known etiology. The most frequent symptoms of onset are hemorrhage in adults and ischemia in children. In the treatment of moyamoya disease revascularization surgery is performed in order to decrease the vascular fragility. A specialized care is required in the perioperative period since surgery is often complicated by cerebral ischemia or cerebral hemorrhage. Aim in the perioperative anesthetic management is to provide the balance between oxygen supply to and use in the brain. In this case report we aimed to discuss the anesthetic management in a 22-year-old male patient with moyamoya disease in whom a multipl burr hole surgery was performed. © Gülhane Askeri Ti{dotless}p Akademisi 2010.

Purpose: To evaluate acid-etching effects prior to the application of self-etching primer and the effect of different primer application techniques on dentin shear bond strength (SBS). Materials and Methods: Forty human third molar cervical regions were used in this study. The teeth were randomly divided into four groups (n = 10) of different tooth surface conditions: group A: Clearfil Protect Primer applied gently (inactive) + Clearfil Protect Bond; group B: 38% phosphoric acid for 15 s, rinsed 15 s, and dried 15 s + Clearfil Protect Primer applied gently (inactive) + Clearfil Protect Bond; group C: Clearfil Protect Primer applied with agitation by microapplicator brush (active) + Clearfil Protect Bond; group D: 38% phosphoric acid for 15 s, rinsed 15 s, and dried 15 s + Clearfil Protect Primer applied with agitation by microapplicator brush (active) + Clearfil Protect Bond. The SBS test was performed with a universal testing machine at a crosshead speed of 1 mm/min. Data were analyzed with one-way ANOVA and Tukey HSD tests. Results: The mean SBS values (MPa) and standard deviations are as follows: group A: 36.0 ± 8.3; group B: 24.0 ± 3.9; group C: 35.0 ± 3.3; group D: 30.6 ± 6.7. Conclusion: Acid etching decreased the SBS of the self-etching bonding system to dentin. Active primer application increased the SBS only in acid-etched groups.

WOS: 000403448200013 Objectives: It was aimed to evaluate histological effects of different doses of dexmedetomidine on lung injury induced by liver ischemia-reperfusion in rats. Materials and methods: Forty rats were included into the study in Inonu University Animal laboratory at 2013, In Group 1, the liver was manipulated and no occlusion of the vessels of the liver was performed. In IR Group 2, 60 min of ischemia and 60 min of reperfusion were applied. In Group 3, 10 mu g/kg of dexmedetomidine was injected into the peritoneal cavity 30 min before ischemia. In Group 4, 100 mu g/kg of dexmedetomidine was administered via intraperitoneal route 30 min before ischemia. Further procedures in groups 3 and 4 were the same as those of group 2. After the experiment was completed, the rats were killed and then histologic assessments were performed to the lung tissues. Results: Histopathological damage score in group 2 was higher than in group 1. Although lung damage was recognized as alleviated in group 3, the lesions did not completely improve. However, treatment with 100 mu g/kg of dexmedetomidine was more effective than 10 mu g/kg of dexmedetomidine injection in respect to protection of alveolar structures. The difference was found to be statistically significant between group 3 and group 4 in terms of histopathological damage score. Conclusions: The present study suggests that dexmedetomidine administration may be beneficial for preventing lung injury induced by hepatic IR.

The purpose of this study was to determine the flexural strength (FS), flexural modulus (FM), depth of cure (DC), polymerization shrinkage (PS), and microhardness (VH) of the following composites: • Two packable composites - Filtek P-60 and Solitaire 2; • One ion-releasing composite -Ariston AT; and • Two hybrid composites -Charisma and Filtek Z-250. Data of the different tests conducted were obtained as follows: • FS and FM data were determined with a universal-testing machine; • Polymerization shrinkage was determined using the apparatus of Watts and Cash; • Depth of cure was measured with a micrometer (Mitotuyo, UK); and • Microhardness was measured with a Shimadzu Microhardness tester (500 g, 15 seconds). All data of the different tests were statistically analyzed by one-way variance analysis (ANOVA), which yielded the following results: • Filtek Z-250 showed the statistically highest flexural strength and modulus values. • Solitaire 2 exhibited the highest shrinkage, while the volumetric shrinkage results of Filtek Z-250 and Filtek P-60 ranked the lowest. • For depth of cure, there were no statistically significant differences among all materials tested (p Ariston AT=Solitaire 2=Charisma.

Aim The purpose of this study was to evaluate the fracture resistance of endodontically treated maxillary central incisors restored with quartz fiber posts, composite cores, and crowns when different types of ferrule designs were incorporated. Methods and Materials Sixty maxillary incisors were divided into six groups: Group 1 (control): teeth with root canal treatments having a full crown prosthesis; Group 2: teeth with a 2 mm circumferential ferrule; Group 3: teeth with a 2 mm ferrule only in the vestibular region; Group 4: teeth with a 2 mm ferrule only in the palatal region; Group 5: teeth with a 2 mm ferrule in the vestibular and palatal region, having cavities in both proximal areas; and Group 6: teeth with no ferrule. The teeth in the experimental groups were restored with quartz fiber posts-composite cores and full metallic crowns. All experimental teeth were subjected to an increasing compressive force with a crosshead speed of 1 mm/min, until fracture occurred. Results The median fracture values of groups were as follows: Group 1: 574.4 N, Group 2: 472.4 N, Group 3: 474.3 N, Group 4: 480.7 N, Group 5: 463.1 N, and Group 6: 297.9 N. A statistically significant difference was found between Group 1 and Group 6 (p< 0.01). Conclusion It was concluded different ferrule designs did not have any influence on the fracture resistance of teeth with fiber posts. The results of this study indicate fiber posts can safely be used for their reinforcing properties. Furthermore, there is no significant change in the resistance of teeth with fiber posts regardless of which ferrule design is incorporated. The property of these types of posts is an additional advantage in clinical practice. Citation Dikbas I, Tanalp J, Ozel E, Koksal T, Ersoy M.
