- MakaleYalnız künye2021Scopus SJRQ1Determination of START triage skill and knowledge levels of Prehospital Emergency Medical Staff: A cross sectional study
Aslan, Ramazan; Şahinöz, Saime; Şahinöz, Turgut
Background: Emergency medical staff working in pre-hospital (PH-staff) may encounter mass casualty incident (MCI) events. In these events these medical personnel should perform triage. The objective of this study is to determine the skill and knowledge levels of PH-staff about Simple Triage and Rapid Treatment (START) triage. Methods: With this cross-sectional, observational study we analyzed data from 127 PH-staff. Data was collected with the survey tool (response rate = 74.7%). Kruskal-Wallis H Test, Mann-Whitney U Test, and Spearman's Correlation analyzes were used in the data analysis by means of SPSS Software. Results: Of the participants, 63% were men, the median age was 24 years, 88 PH-staff (69.3%) intervened in MCI events, and 37 PH-staff (29.1%) applied START triage. The skill score was 60% and the knowledge score was 72.5%. There was a weak positive correlation between knowledge and skill scores (r = 0.337, p < 0.01). The knowledge level of the emergency medical technicians (EMTs) and paramedics was higher than those from the other professions. Conclusions: The triage knowledge and skill levels of the PH-staff were not low contrary to the expectations. The triage knowledge and skill levels of professions that did not have pre-hospital training such as paramedics and EMTs were low.

Tekce, E.; Bayraktar, B.; Aksakal, V.; Dertli, E.; Kamiloğlu, A.; Çinar Topçu, K.; Kaya, H.; Takma, C.; Yasulergezer, N.
In the present study, the effects of Lactobacillus reuteri E81 (LRE) supplemented at different doses (200, 400 and 600 mg/kg) into the diets on performance, meat quality and internal organ weights of Japanese quail (Coturnixcoturnix japonica) were investigated under heat stress (HS) conditions (37°C). For the experiments, 448 one-day old quails were used. Seven days of training (physical exercise) and a 35-day fattening period were applied. On day 7 of the trial, 8 groups [4 under control temperature of 25°C (CT): control (C), LRE-200, LRE-400 and LRE-600 and 4 under HS: control (HSC), SLRE-200, SLRE-400 and SLRE-600] were formed, each group consisting of four replicates with 14 quail each. At the end of this study, the CT group fed 400 mg/kg LRE showed the best performance results, whereas no effect was found for groups under HS in comparison to the control group (HSC). Samples taken on the 21st and 42nd day revealed that addition of probiotics in the CT and HS groups induced no effect on weight of the internal organs (p > 0.05). Analysis of meat quality on the 21st day showed that LRE caused an increase in pH in both the HS and CT groups. Further, 400-mg/kg LRE supplementation induced an increase in thiobarbituric acid reactive substances (TBARS) in the group under HS. In the CT groups on day 42 no effect of LRE was found on colour parameters or on the TBARS value, except for a decrease in the pH value in the LRE supplemented groups compared with the control. In HS groups a decrease in the L* value and an increase in the TBARS value was found compared to CT groups (p < 0.05), but there was no effect on other colour parameters or pH value. In conclusion, in the present study supplementation of different doses of LRE E81 to quail diets had no effect on performance, internal organ weight or meat quality under HS.

Kaya, Yusuf; Polat, Alper; Özşahin, Talat Şükrü
In this study, we solve the continuous contact problem of two layers with different material properties, loaded with two rigid flat blocks and resting on a rigid plane, by analytical and finite element methods. All surfaces are assumed to be frictionless. The upper layer is the functionally graded layer (FG), the height h1, the underlying layer is homogeneous, and the height is h2. It is assumed that the FG layer is isotropic and that the shear modulus and density change exponentially. The FG layer is loaded by means of two rigid flat blocks whose external loads are Q and P (per unit thickness in z direction). In the analytical solution of the problem, stress and displacement expressions are substituted in the boundary conditions and the problem is demoted to singular integral equations where the contact stresses are the unknown functions. These singular integral equations are solved numerically using the Gauss–Chebyshev integration formulas. Two-dimensional finite element analysis of the problem is performed using the ANSYS package program. The analyses are performed for different shear modulus ratios (μ2/μ-h1), distances between the blocks ((c − b)/h1) and inhomogeneity parameters (βh1). The contact stresses under the blocks, the normal stresses (σy) between interfaces of the FG layer and the homogeneous layer and between the homogeneous layer and rigid plane are also measured. In addition, the initial separation load and the initial separation distances (χcr, λcr) of the FG layer and homogeneous layer are determined. The results are presented comparatively as graphs and tables.

Genc, Berna; Taskin, Mesut; Adiguzel, Ahmet
Exopolysaccharides (EPS/EPSs) possess several various applications in the food and pharmaceutical industries. This study was performed to investigate the biological (antibiofilm and antitumor), rheological (temperature, shear rate, and density) and chemical (solubility, carbohydrate and protein content, composition, molecular weight, functional group analysis, thermal analysis, X-ray diffraction pattern and scanning electron microscopy) properties of the EPS, which was purified from the locally isolated thermophilic bacterium Anoxybacillus pushchinoensis G11 (MN720646). EPS was found to have antibiofilm and antitumor [lung (A-549) and colon (Caco-2 and HT-29) cancer] activities. The viscosity of EPS showing Newtonian flow was temperature dependent. As chemical properties, the EPS was found to be a heteropolysaccharide containing arabinose (57%), fructose (26%), glucose (12%), and galactose (5%). EPS contained 93% carbohydrates and 1.08% protein. The molecular weight of EPS was determined as 75.5 kDa. The FTIR analysis confirmed the presence of sulfate ester (band at 1217 cm−1), an indication of the antitumor effect. The EPS was semi-crystalline. It could maintain 36% of its weight at 800 °C and crystallization and melting temperatures were 221 and 255.6 °C. This is the first report on the EPS production potential and the biological activity of A. pushchinoensis.

Ünlü, Ramazan
Manual detection of abnormality in control data is an annoying work which requires a specialized person. Automatic detection might be simpler and effective. Various methodologies such as ANN, SVM, Fuzzy Logic, etc. have been implemented into the control chart patterns to detect abnormal patterns in real time. In general, control chart data is imbalanced, meaning the rate of minority class (abnormal pattern) is much lower than the rate of normal class (normal pattern). To take this fact into consideration, authors implemented a weighting strategy in conjunction with ANN and investigated the performance of weighted ANN for several abnormal patterns, then compared its performance with regular ANN. This comparison is also made under different conditions, for example, abnormal and normal patterns are separable, partially separable, inseparable and the length of data is fixed as being 10, 20, and 30 for each. Based on numerical results, weighting policy can better predict in some of the cases in terms of classifying samples belonging to minority class to the correct class.

Kurnaz, Muammer; Şahin, Mehmet Kürşat
The Anatolian newt, Neurergus strauchii, is an endemic Anatolian species. Until recently, N. strauchii was represented by three subspecies. It has been discussed within a recent phylogenetic study in which the subspecies N. s. barani is recommended to be evaluated as a cryptic but distinct species. To address this subject, we aimed to discuss the niche differentiation between N. barani and N. strauchii using geographical and bioclimatic aspects. All georeferenced data of N. barani and N. strauchii were used to estimate the potential distributions of these species in the Anatolian Peninsula. To evaluate their ecological niche differentiation, point-based analysis and niche similarity tests were done. Ecological niche modeling outcomes demonstrated a significant niche differentiation between N. barani and N. strauchii. Moreover, since these species are distributed in the east and west of the Euphrates Basin, this river might be considered as a geographic barrier that can cause isolation for these species. Lastly, we demonstrated their potential distributions for future with several scenarios. Our findings strengthened the results of the recent phylogenetic study and indicated the necessity of handling “barani” taxa at the species level. Moreover, these results contribute, as a piece of evidence, to the biodiversity of Anatolia where another endemic species lives.

Nilgün-Doğan, Üyesi; Adanacıoğlu, Hakan
The main objective of this study was to assess the relationship between the level of consumers perception of products with geographical indication (GI) and their consumption of products with GI labels. Geographically indicated products were examined within the scope of Gumushane fruit pulp (mulberry pestil), which was registered as a Protected Geographical Indication (PGI) in 2004. This research conducted an online survey of 166 consumers living in Gumushane province in Turkey. Data was obtained from the online surveys that were conducted between June and September 2020. Binary logistic regression analysis method was used to identify the factors affecting the probability of consuming products with GI labels. The model results show that middle-aged, married, and middle-income and consumers who correctly perceive the concept of geographical indication products are more likely to consume products with GI labels. According to the logistic regression results, the increase in consumers level of correct perception of the product notion with GI label increases the probability of consuming products with GI label 2.5 times. The results of this study also tell us that the market share of these products can be increased by improving the consumer perception towards geographically indicated products. Policymakers can also take advantage of these insights to improve lucid understanding of how labels are actually interpreted by consumers.

Şenaslan, Fatih; Taşdemir, Muharrem; Çelik, Ayhan
Nickel oxide (NiO) films were deposited on glass and silicon substrates using a Ni target by radio-frequency (RF) sputtering at various working pressure ranging from 5 to 20 mTorr. The films were annealed for 2 h at 400 °C in the air ambient. The effect of working pressure on structural, optical and electrical properties of NiO films was investigated in detail. The deposition rate of the films gradually increased with decreasing working pressure. The X-ray diffraction (XRD) presented that the crystal quality and the average crystallite size of annealed films increased with decreasing working pressure. The X-ray photoelectron spectroscopy (XPS) confirmed the presence of Ni2+ and Ni3+ ions along with the main peak and satellite peaks in the NiO films. Raman spectroscopy exhibited the one-phonon and two-phonon vibrations modes corresponding to Ni–O bond. UV–Visible analyses showed that annealed NiO thin films have higher transmittance than deposited ones. The band gap of the films increased from 3.33 to 3.52 eV with decreasing working pressure and further increased after the annealing process. The electrical properties were affected by the varying crystallinity and lattice defects depending on the deposition condition. All annealed NiO films exhibited p-type conductivity. The lowest resistivity (4.2 Ω.cm) was obtained from the annealed film after deposition at 5 mTorr.

Study Objectives: In this study, it was aimed to evaluate the relationship between vitamin D and lipid profiles of athletes playing football professionally during the season and some metabolic parameters and maximal rate. Methods: 52 male elite soccer players performing in Super League, TFF 2nd League, and TFF 3rd League whose mean age 22.86±3.55 years, participated in our study. The sport age of the soccer players was 12.2±1.70 years. The participants attended in at least five 80-minute training periods and performed at least one official competition weekly (through 11 months). In November, blood samplings of the athletes and other parameters were obtained between 09:00 and 10:00 a. m. leading a 12-hour fasting period. The Maximal Aerobic Speed (MAS) measurement developed by Buchheit (2008) to evaluate aerobic power and capacity was used to carry out the study. In order to determine the relationship between the variables of individuals, Pearson Correlation Test was used as the data showed normal distribution. Results: Albumin, Alp, Alt, Ast, B12 vitamin, Ca, Phosphorus, Creatinine, Mg, Free T3, Sodium, Tsh, Ferritin, Folic Acid, Potassium Triglyceride, Glucose, Total Cholesterol, and Free T4 values were found within normal limits. It can be said that athletes had low vitamin D values. It was observed that the participants had low LDL cholesterol values. Variables don’t have any significant effects on running time, peak velocity, true vift and VO2max of biochemical parameters (p>0,05). Conclusion: As a result, it can be concluded that despite the positive relationship between the maximal aerobic velocity test parameters of the footballers and their pre-test biochemical results, it wasn’t statistically a meaningful relationship.

Kucukosman, Rıdvan; Sukuroglu, Ebru Emine; Totik, Yasar; Sukuroglu, Suleyman
Graphene oxide (GO) integrated composite coatings were deposited on AZ91 magnesium alloys by the PEO (Plasma Electrolytic Oxidation) and the treatment which has a post-PEO hydrothermal process. For the first group samples, PEO was performed in the silicate/phosphate-based electrolyte including 5–10 µm in size the GO particles synthesized using the Tour Method. For the second group samples, after PEO treatment, the post-PEO hydrothermal process was carried out in the oven in the GO-distilled water mixture containing GO produced with the same protocol. The effects of GO on wear behavior, structural and morphological features of composite coatings were examined with a pin-on-disc tribometer, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy, respectively. The results showed that the addition of GO improved significantly the adhesion to the substrate material of composite coatings, increased the coating thickness and hardness. Post-PEO hydrothermal process resulted in the formation of partial a thin solid lubricant GO film on the surface of composite coatings and thus exhibited the best wear and friction resistance.

Sengul, Suleyman; Bekiryazici, Zafer; Merdan, Mehmet
In this paper, Wong-Zakai approximation methods are presented for some stochastic differential equations in engineering sciences. Wong-Zakai approximate solutions of the equations are analyzed and the numerical results are compared with results from popular approximation schemes for stochastic differential equations such as Euler-Maruyama and Milstein methods. Several differential equations from engineering problems containing stochastic noise are investigated as numerical examples. Results show that Wong-Zakai method is a reliable tool for studying stochastic differential equations and can be used as an alternative for the known approximation techniques for stochastic models.

Çelik, Ilhan; Alsaran, Akgün; Purcek, Gencaga
Four different surface oxidation treatments, so-called, anodizing oxidation (AO), micro-arc oxidation (MAO), plasma oxidation (PO) and thermal oxidation (TO), were applied to ultrafine-grained (UFG) pure titanium produced by equal-channel angular extrusion/pressing (ECAE/P). Before and after all treatments, mechanical, structural and tribological properties were investigated. The strength of pure titanium increased substantially after ECAE process. TiO2 phases included the anatase and/or the rutile formed on the surface of UFG Ti depending on oxidation treatments. High strength of UFG Ti was deteriorated by TO and PO treatments because of the recrystallization occurred at high-temperature, while applications of MAO and AO did not cause a significant decrease in its strength due to the prevention of recrystallization of UFG Ti. All oxidation treatments brought about a remarkable increase in wear resistance of UFG Ti because of the formation of adhered and hard TiO2 film developed on the surface. It was concluded that the AO and MAO treatments could be applied to the UFG Ti without any deteriorations in bulk mechanical and wear properties to obtain biocompatible pure titanium with high strength and excellent wear resistance.

Kaplan, Mahmut; Yüksel, Ferhat; Karaman, Kevser
In this study, deep fried gluten free chips were manufactured using sorghum flour at different concentrations (5, 20, 35 and 50 g/100 g) and in vitro glycemic index, total antioxidant capacity and some physicochemical characteristics (dry matter, ash, oil, protein and color) and overall acceptability of the samples were investigated. Protein, oil and total dietary fiber levels of the samples ranged between 5.39–8.28, 23.58–29.10 and 5.59–6.60 g/100 g, respectively and increase in sorghum flour level resulted in an increase in these studied quality parameters of the chips samples. Ferric reducing antioxidant activity and DPPH radical scavenging performance were affected positively by the addition of sorghum flour. Total starch hydrolysis index and estimated glycemic index values were affected by the sorghum flour addition negatively due to the increased total dietary fiber content of the chips samples. All chips samples enriched with sorghum flour showed similar overall acceptability and increased sorghum concentration decreased the preference scores slightly. All these results could be considered for the manufacturing of the gluten free deep fried sorghum based chips samples.

Melek, Mesut; Manshouri, Negin; Kayikcioglu, Temel
Different biological signals are recorded in sleep labs during sleep for the diagnosis and treatment of human sleep problems. Classification of sleep stages with electroencephalography (EEG) is preferred to other biological signals due to its advantages such as providing clinical information, cost-effectiveness, comfort, and ease of use. The evaluation of EEG signals taken during sleep by clinicians is a tiring, time-consuming, and error-prone method. Therefore, it is clinically mandatory to determine sleep stages by using software-supported systems. Like all classification problems, the accuracy rate is used to compare the performance of studies in this domain, but this metric can be accurate when the number of observations is equal in classes. However, since there is not an equal number of observations in sleep stages, this metric is insufficient in the evaluation of such systems. For this purpose, in recent years, Cohen’s kappa coefficient and even the sensitivity of NREM1 have been used for comparing the performance of these systems. Still, none of them examine the system from all dimensions. Therefore, in this study, two new metrics based on the polygon area metric, called the normalized area of sensitivity polygon and normalized area of the general polygon, are proposed for the performance evaluation of sleep staging systems. In addition, a new sleep staging system is introduced using the applications offered by the MATLAB program. The existing systems discussed in the literature were examined with the proposed metrics, and the best systems were compared with the proposed sleep staging system. According to the results, the proposed system excels in comparison with the most advanced machine learning methods. The single-channel method introduced based on the proposed metrics can be used for robust and reliable sleep stage classification from all dimensions required for real-time applications.

In our country, Home Health Care (HHC) units support people who are fully bed-dependent in order to provide health services at the right time, place and conditions. Vehicle Routing Problem (VRP) is used for cost, speed and distance optimization in delivering products or services to customers. In addition, there will be improvements in HHC and it will also save on transportation, storage and labor costs by determining the most appropriate VRP’s solution methods. In this respect, the aim of this study is to determine the best VRP’s solution method which can increase the efficiency of HHC. The proposed approach is based on Intuitionistic Fuzzy Analytic Hierarchy Process (IF-AHP) method which is a strong technique for dealing with uncertainties. According to results, the most important criteria is “time based factors”. Meta-heuristic is the appropriate solution algorithms for VRP in HHC.

Coruh, Emine; Urak, Faruk; Bilgic, Abdulbaki; Yen, Steven T.
Factors at the family scale, for which dynamic decisions and proper investments need to be made at the national level in curbing greenhouse gas emissions, are extremely important for policymakers and investors. We provide information on the roles of how household demographic factors shape transportation patterns and spending in Turkey using the latest survey data collected by the Turkish Statistical Institute (TSI). Alternative sample selection models are estimated to accommodate censoring in expenditure, and the dependent single-hurdle model is found to be the preferred model as a result of model specification tests. Also, different specification tests conducted, including the error-independence test, resulted in rejection of the null hypothesis. Results suggest that the majority of the household economic and sociodemographic characteristics are important determinants of both the probability and level of transportation expenditure. Policy recommendations to curb carbon emissions and integrate environmentally friendly transport systems throughout the country are presented.

BEDER, M.; ALEMDAG, Y.
The aim of the present study was to investigate the influence of Mg addition and T6 heat treatment on microstructure, mechanical and tribological properties of the Al–Si–Cu–Mg alloys. In this context, a series of Al–12Si–3Cu–(0.5–2.5)Mg (wt.%) alloys were produced by permanent mould casting, and then subjected to T6 treatment. Their microstructure and mechanical properties were investigated using OM, XRD, SEM, EDS along with hardness, tension, compression and Charpy impact tests. Dry sliding friction and wear properties of the alloys were studied using a ball-on-disk type tester. It was observed that the microstructure of as-cast Al–12Si–3Cu–Mg alloys consisted of α(Al), Si, θ-CuAl2, β-Mg2Si, Q-Al5Mg8Cu2Si6 and π-Al8Mg3FeSi6 phases. T6 heat treatment gave rise to nearly spherodization of eutectic Si particles, formation of finer θ-CuAl2 and β-Mg2Si precipitates and elimination of Chinese script morphology of β-Mg2Si phase. The addition of Mg up to 2.5 wt.% decreased the hardness, tensile and compressive strengths, tensile elongation and impact toughness of the as-cast and T6-treated alloys and increased their friction coefficient and volume loss. T6 treatment, on the other hand, led to a significant increase in mechanical properties and wear resistance of as-cast alloys.
