TURKISH ECONOMY AND COMPARATIVE MAIN INDICATORS Turgut Ozkan After the global crisis which started in 2008, the production balance of the world shifted to Asia. Refraining from producing solutions for structural economic problems of Western countries caused them to be passive against this change. Turkey, analyzed the global change correctly, has canalized to have a correct position by making unimportant the policy of integration to the west which has maintained desperately for years. This study aims to determine whether Turkey has adequate economic and financial performance for the new roadmap or not. Thus, the main economic and financial indicators of Turkey are analyzed comparatively with other countries. A conclusion was reached that Turkey economy has a strong, effective and sustainable economic and financial performance except for the problems of unemployment and inflation.

In this study, the effects of chronically administered aluminum on iron metabolism-related parameters of liver and blood of mice were investigated. An additional purpose to determine how chronic aluminum administration together with vitamin E as an antioxidant to mice changed the parameters related to iron metabolism. For these purposes, we used 21 adult female Balb-c mice in this study. The animals were divided into three groups: one group with aluminum administered chronically, another group with aluminum plus vitamin E administered chronically, and the control group. Serum levels of hemoglobin, ferritin, iron, transferrin, hematocrit, total iron binding capacity (TIBC), as well as percentage of transferrin saturation were determined in all groups. In addition, the liver tissue levels of ferritin and iron were analyzed. Hemoglobin and hematocrit levels of the aluminum group and aluminum plus vitamin E group were significantly decreased compared to the control. In conclusion, no changes occurred in the serum iron related parameters although Al induced anemia in mice when Al administered chronically. There was an increase in the levels of liver iron and ferritin with Al, but Vit E had no effect on the changes of all blood and liver parameters caused by Al.

Turgut Kocatürk,Seref Doguscan Akbas 국제구조공학회 2012 Structural Engineering and Mechanics, An Int'l Jou Vol.41 No.6

This paper focuses on post-buckling analysis of functionally graded Timoshenko beam subjected to thermal loading by using the total Lagrangian Timoshenko beam element approximation. Material properties of the beam change in the thickness direction according to a power-law function. The beam is clamped at both ends. The considered highly non-linear problem is solved by using incremental displacement-based finite element method in conjunction with Newton-Raphson iteration method. As far as the authors know, there is no study on the post-buckling analysis of functionally graded Timoshenko beams under thermal loading considering full geometric non-linearity investigated by using finite element method. The convergence studies are made and the obtained results are compared with the published results. In the study, with the effects of material gradient property and thermal load, the relationships between deflections, end constraint forces, thermal buckling configuration and stress distributions through the thickness of the beams are illustrated in detail in post-buckling case.

High School Teachers’ Perceptions Regarding Principals’ Ethical Leadership in Turkey

Turgut Karaköse 서울대학교 교육연구소 2007 Asia Pacific Education Review Vol.8 No.3

This study has been carried out in order to determine to what extent principals demonstrate ethical leadership behaviors, and to present suggestions on the strength of these findings. The study has a descriptive quality in evaluating the teachers’ perceptions and uses the Ethical Leadership Scale (ELS) developed by Yilmaz (2006), so as to determine the opinions of the participant teachers. The analysis of the data has been performed via the “SPSS for Windows ” package program. In addition, such statistical processes as a significance test, standard deviation, one-way variance analysis (ANOVA), Kruskal-Wallis H Test, Mann-Whitney U Test have also been carried out. The findings reveal that principalsadequately perform their ethical responsibilities like treating their staff justly and encouraging them, being fair, understanding, patient and humble, traits which all exist in the “communicative ethics, climatic ethics and ethics in decision making ” levels at the state high schools in the city of Kütahya, Turkey. On the other hand, the participant teachers in the study have clearly admitted that the principals engaged in such ethical behaviors in the “behavioral ethics ” level as self-evaluation, not lying and protecting individual rightspoorly.

How will surface treatments affect the translucency of porcelain laminate veneers?

Turgut, Sedanur,Bagis, Bora,Ayaz, Elif Aydogan,Korkmaz, Fatih Mehmet,Ulusoy, Kivanc Utku,Bagis, Yildirim Hakan The Korean Academy of Prosthodonitics 2014 The Journal of Advanced Prosthodontics Vol.6 No.1

PURPOSE. The purpose of this study was to evaluate whether surface treatments affect the translucency of laminate veneers with different shades and thicknesses. MATERIALS AND METHODS. A total of 224 disc-shaped ceramic veneers were prepared from A1, A3, HT (High Translucent) and HO (High Opaque) shades of IPS e.max Press (Ivoclar Vivadent) with 0.5 mm and 1.0 mm thicknesses. The ceramics were divided into four groups for surface treatments. Group C: no surface treatments; Group HF: etched with hydrofluoric acid; Group SB: sandblasted with 50-${\mu}m$ $Al_2O_3$; and Group L; irradiated with an Er;YAG laser. A translucent shade of resin cement (Rely X Veneer, 3M ESPE) was chosen for cementation. The color values of the veneers were measured with a colorimeter and translucency parameter (TP) values were calculated. A three-way ANOVA with interactions for TP values was performed and Bonferroni tests were used when appropriate (${\alpha}=0.05$). RESULTS. There were significant interactions between the surface treatments, ceramic shades and thicknesses (P=.001). For the 0.5-mm-thick specimens there were significant differences after the SB and L treatments. There was no significant difference between the HF and C treatments for any shades or thicknesses (P>.05). For the 1-mm-thick ceramics, there was only a significant difference between the L and C treatments for the HT shade ceramics (P=.01). There were also significant differences between the SB and C treatments except not for the HO shades (P=.768). CONCLUSION. The SB and L treatments caused laminate veneers to become more opaque; however, HF treatment did not affect the TP values. When the laminate veneers were thinner, both the shade of the ceramic and the SB and laser treatments had a greater effect on the TP values.

Turgut Donmez,Adnan Hut,Huseyin Avaroglu,Sinan Uzman,Dogan Yildirim,Sina Ferahman,Erdinc Cekic 대한외과학회 2016 Annals of Surgical Treatment and Research(ASRT) Vol.91 No.2

Purpose: The 2-port laparoscopic appendectomy technique (TLA) is between the conventional 3-port and single-port laparoscopic appendectomy surgeries. We compared postoperative pain and cosmetic results after TLA with conventional laparoscopic appendectomy (CLA) by a 3-port device. Methods: Patients undergoing TLA were matched with patients undergoing CLA between February 2015 and November 2015 at the same institution. Thirty-two patients underwent TLA with a needle grasper. The appendix was secured by a percutaneous organ-holding device (needle grasper), then removed through a puncture at McBurney’s point. Another 38 patients underwent CLA. Patient demographics, operative details, and postoperative outcomes were collected and evaluated. Results: One patient in the TLA group developed a wound infection and 1 patient in the CLA group developed a postoperative intra-abdominal abscess and 3 wound infections. There was no significant difference between the groups when comparing the length of hospital stay, time until oral intake, and other complications. The pain score in the first 12 hours after surgery was significanly higher in CLA group than the TLA group (P < 0.001). Operative time was significantly shorter in the CLA group compared to the TLA group (P < 0.001). Conclusion: TLA using a needle grasper was associated with a significantly lower pain score 12 hours after surgery, better cosmetic results, and lower cost, than the CLA 3-port procedure because of the fewer number of ports.

Preparation of chitosan, sunflower and nano-iron based core shell and its use in dye removal

Turgut, Esra,Alayli, Azize,Nadaroglu, Hayrunnisa Techno-Press 2020 Advances in environmental research Vol.9 No.2

Many industries, such as textiles, chemical refineries, leather, plastics and paper, use different dyes in various process steps. At the same time, these industrial sectors are responsible for discharging contaminants that are harmful and toxic to humans and microorganisms by introducing synthetic dyes into wastewater. Of these dyes, methylene blue dye, which is classified as basic dyes, is accepted as a model dye. For this reason, methylene blue dye was selected in the study and its removal from the water was studied. In this study, two efficient biosorbents were developed from chitosan and sunflower waste, an agro-industrial waste and modified using iron nanoparticles. The biosorption efficiency was evaluated for methylene blue (MB) dye removal from aqueous solution under various parameters such as treating agent, solution pH, biosorbent dosage, contact time, initial dye concentration and temperature. We investigated the kinetic properties of dye removal from water for Chitosan-Sunflower (CS), Chitosan-Sunflower-Nanoiron (CSN). When the wavelength of MB dye was spectrophotometrically scanned, the maximum absorbance was determined as 660 nm. For the core shell biosorbents we obtained, we found that the optimum time for removal of MB from wastewater was 60 min. The pH of the best pH was determined as 5 in the studied pH. The most suitable temperature for the experiment was determined as 30℃. SEM-EDAX, TEM, XRD, and FTIR techniques were used to characterize biosorbents produced and modified in the experimental stage and to monitor the change of biosorbent after dye removal. The interactions of the paint with the surface used for removal were explained by these techniques. It was calculated that 80% of CS and 88% of CSN removed MB in optimum conditions. Also, the absorption of MB dye onto the surface was investigated by Langmiur and Frendlinch isotherms and it was determined from the results that the removal was more compatible with Langmiur isotherm.
