Background Perforations in the nasal septum (NSP) give rise not only to disintegration of the septum anatomy but also impairment in normal nasal physiology. The successes of these surgical techniques are usually equated to anatomical closure of the perforation. The goal of this study is to evaluate the subjective and objective results of our surgical technique for septal perforation surgery. Methods All NSPs in the six patients were closed by inferior turbinate flap. The Nasal Obstruction Symptom Evaluation (NOSE) instrument was used to evaluate the preoperative and postoperative subjective sensation of nasal obstruction. Measurement of preoperative and postoperative nasal airway resistance was performed using active anterior rhinomanometry which is an objective test. Wilcoxson signed rank test and Spearman correlation test were used to analyze correlation between NOSE scores and rhinomanometric measurements. Results The full closure of the septal perforations was noted in 100% of patients. The total NOSE score was 14 preoperatively and one postoperatively. The improvement in NOSE scores was statistically significant ($P{\leq}0.002$). The mean preoperative total resistance (ResT150) value was $0.13Pa/cm^3s^{-1}$, which is below the normal range ($0.16-0.31Pa/cm^3s^{-1}$), while the mean postoperative ResT150 value was $0.27Pa/cm^3s^{-1}$. The correlation between the improvement in NOSE scores and improvements in ResT150 values was statistically significant. Conclusions Surgical approaches should aim to solve both the anatomical and physiological problems of NSP. The application of subjective and objective tests in the postoperative period will help surgeons assess the applied techniques.

NO<SUB>x</SUB> emission modeling at cement plants with co-processing alternative fuels using ANN

Betul OZTURK,Onur OZTURK,Aykan KARADEM?R 대한환경공학회 2022 Environmental Engineering Research Vol.27 No.5

The use of wastes as alternative fuel (AF) at the cement plants for clinkerization processes has increased in recent years as sustainable waste management. Such co-processing of AFs at cement plants causes some changes in the composition of the plant emissions, depending on waste type, kiln thermal power, thermal substitution rate, etc. Emissions of nitrogen oxides (NOx) are among the major environmental concerns in these plants. The paper includes a modeling study of NOx emissions at a cement plant during the co-processing of AFs. Due to the non-linear characteristic of the relationship between operational parameters and NOx emissions, the artificial neural network (ANN) approach was applied and studied. The study showed that NOx emissions can be predicted satisfactorily by using ANN at cement plants. Therefore, the model proposed may be used by cement plant operators to estimate their emission levels before starting the use of a new fuel source.

Onder Ozturk,Unal Ozturk,Sebnem Nergiz,M. Zulkif Karahan 대한심장학회 2016 Korean Circulation Journal Vol.46 No.6

Background and Objectives: Genetic influence on T-wave peak to End (Tpe) time in patients with a first anterior acute myocardial infarction (AMI) is uncertain. A polymorphism in the angiotensin-II type 1 receptor (AT1R) gene was discovered recently. The polymorphism consists of an A or C variant, given three different possible genotypes: AA, AC, CC. The purpose of this study was to determine the effects of polymorphism of the AT1R gene polymorphism on Tpe after a first anterior AMI. Subjects and Methods: The subjects were 142 patients (110 men, 32 women, 58±13 years) with a first anterior AMI; ten patients were excluded from this study. Based on the polymorphism of the AT1R gene, they were classified into two groups: Group 1 (AA genotype) of 91 patients and group 2 (AC and CC genotype) of 41 patients. A 12-lead resting ECG was recorded at admission to the coronary care unit in patients with anterior AMI and were manually measured with a ruler. QTc, QTd, QTcd, Tpe, Tpe/QT parameters were measured. Results: There was no significant difference in the baseline characteristics of patients (p>0.05). We found significant reduction in QTc, QTd, QTcd, Tpe, Tpe/QT indices Group 1 (AA genotype) (mean 66±28 ms) than group 2 (AC and CC genotype) (mean 95±34 ms) (p<0.05). Conclusion: In patients with a first anterior AMI, AT1R gene polymorphisms may influence on repolarization parameters. Although further studies are required.

Ozturk, Ahmet,Unalan, Demet,Guleser, Gulsum Nihal Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.23

Background: The present study was conducted to determine knowledge level of technicians working in hospitals about testicular cancer (TC) and self-examination of testicles (TSE) and to determine levels of consciousness and implementation status about TSE. Materials and Methods: This cross-sectional study was conducted with technicians working in hospitals (n=243) between $2^{nd}$ January-$31^{st}$ May 2012 at private and governmental hospitals in urban Kayseri. Healthy control subjects (n=235) who were similar to technicians in terms of age, education level and income status were also included to the study. Chi-square test was used in comparison of categorical variables. Results: Technicians were significantly more aware of TC than controls, but the latter were found to have significantly more information about TSE. There was no significant difference between the two groups in terms of knowing how to do TSE and 80% of both groups were unaware this exam. Of technicians, 19.8% and of controls, 25.5% did TSE, the difference being statistically insignificant. First reason for not doing TSE was "not-knowing" among technicians (48.1%) while it was "ignorance" among controls (66.8%). Of technicians doing TSE, 37.5% did as it came to their mind while 51.7% of controls performed TSE several times in the previous year. Technicians were significantly more afraid of getting TC than controls (p=0.037). Conclusions: It was determined in the present study that rates of TSE were similar between technicians and controls. However compliance with the recommended frequency and right method was low. Consequently, public health education should be planned and applied in order to increase the knowledge of TC and TSE.

Modified finite element-transfer matrix method for the static analysis of structures

Ozturk, D.,Bozdogan, K.,Nuhoglu, A. Techno-Press 2012 Structural Engineering and Mechanics, An Int'l Jou Vol.43 No.6

In this paper the Modified Finite Element-Transfer Matrix Method, which is the combination of Transfer Matrix Method and Finite Element Method, is applied to the static analysis of the structures. In the method, the structure is divided into substructures thus the number of unknowns that need to be worked out is reduced due to the transformation process. The static analysis of the structures can be performed easily and speedily by the proposed method. At the end of the study examples are presented for ensuring the agreement between the proposed method and classic Finite Element Method.

Ozturk, Ismet,Sagdic, Osman,Yetim, Hasan Korean Society for Food Science of Animal Resource 2021 한국축산식품학회지 Vol.41 No.2

The objective of this study was to determine the effects of yeast cultures (Candida zeylanoides and Debaryomyces hansenii) isolated from traditionally dry fermented Turkish sucuks, on some physicochemical and microbiological properties of the product. Eight different batches of the sucuks were produced by the inoculation of yeast and lactic acid bacteria (LAB) cultures (Lactobacillus curvatus, Lactobacillus plantarum and Lactobacillus sakei) in different combinations. The sucuks were ripened for 12 days and analyzed at 1st, 6th, and 12th days of ripening. Percent moisture content, pH, water activity (aw) and residual nitrite values of the sucuk inoculated with the yeast cultures were higher at the end of the ripening. The use of yeast cultures decreased hardness, gumminess, and chewiness values of the sucuk while increased adhesiveness values. Major volatile groups were aldehydes, terpenes, and sulphur compounds in the sucuk samples. The most noticeable results were for sensory properties of the sucuk that were positively improved by the yeast cultures.

A Characterization of Involutes and Evolutes of a Given Curve in 𝔼ⁿ

Ozturk, Gunay,Arslan, Kadri,Bulca, Betul Department of Mathematics 2018 Kyungpook mathematical journal Vol.58 No.1

The orthogonal trajectories of the first tangents of the curve are called the involutes of x. The hyperspheres which have higher order contact with a curve x are known osculating hyperspheres of x. The centers of osculating hyperspheres form a curve which is called generalized evolute of the given curve x in n-dimensional Euclidean space ${\mathbb{E}}^n$. In the present study, we give a characterization of involute curves of order k (resp. evolute curves) of the given curve x in n-dimensional Euclidean space ${\mathbb{E}}^n$. Further, we obtain some results on these type of curves in ${\mathbb{E}}^3$ and ${\mathbb{E}}^4$, respectively.

ON GENERALIZED SYMMETRIC BI-DERIVATIONS IN PRIME RINGS

Ozturk, M. Ali,Sapanci, Mehmet The Youngnam Mathematical Society Korea 1999 East Asian mathematical journal Vol.15 No.2

After the derivation was defined in [19] by Posner a lot of researchers studied the derivations in ring theory in different manners such as in [2], [4], [5], ..., etc. Furthermore, many researches followed the definition of the generalized derivation([3], [6], [7], ..., etc.). Finally, Maksa defined a symmetric bi-derivation and many researches have been done in ring theory by using this definition. In this work, defining a symmetric bi-$\alpha$-derivation, we study the mentioned researches above in the light of this new concept.
