Çimen, Müberra; Düzgün, Azer Özad
The aim of this study was to identify antimicrobial resistance and virulence factor genes exhibited by multidrug resistant (MDR) Acinetobacter baumannii, to analyze biofilm formation and to investigate clonal subtypes of isolate. Whole genome sequencing was done by Illumina NovaSeq 6,000 platform and multilocus sequence typing (MLST) was performed by Oxford and Pasteur typing schemes. Influence of imipenem and levofloxacin on biofilm formation was investigated in 96-well plates at 3 replicates. The strain was found to carry OXA-23, OXA-51-like, AmpC and TEM-1 beta-lactamases. The sequence of the blaOXA-51-like gene has been identified as a blaOXA-66. According to Pasteur MLST scheme the strain displayed ST2 allelic profile. However, based on Oxford MLST scheme this strain represents the new ST2121, as the gdhB gene has a single allelic mutation namely, the gdhB-227. It was determined that MDR isolate carried bap, basABCDFGHIJ, csuA/BABCDE, bauABCDEF, plcD, pgaABCD, entE, barAB, ompA, abaIR, piT2EAFTE/AUBl, fimADT, cvaC, bfmR, bfmS virulence genes. In our study imipenem induced the highest biofilm formation at a concentration of 32 mg/ml and levofloxacin at a concentration of 16 mg/ml. In conclusion, we detected a new MDR A. baumannii ST2121 clone harboring blaOXA-66 gene that has been reported for the first time in Turkey.

Yildirim, Omer; Bozyel, Ibrahim; Saka, Kubra; Kayikcioglu, Temel; Gokcen, Dincer
A capacitive motion sensor that can detect human walking and motions up to a certain distance was designed using polydimethylsiloxane (PDMS) as the primary sensor material. A read-out circuit was designed to detect capacitive coupling with the sensor material caused by the motion in the surrounding. The read-out circuit consists of sensing, filtering, and amplifying stages. A high-pass filter was used to avoid DC components, and to eliminate adverse impacts of 50Hz noise in the sensing signal, a sixth-order low-pass filter consisting of active Sallen–Key and passive RC filters was utilized. The signals obtained from the complete read-out circuit revealed that the sensor system could accurately detect human movements up to 2 m away. Also, different signal patterns were obtained from the output of the sensor system for various human motions.

Menevseoglu, Ahmed; Cabaroglu, Turgut
Turkish Raki is one of the most consumed alcoholic beverages in Turkey. The chemical and metal contamination of alcoholic beverages is a threat to human health and lowers the quality of the product. Ethyl carbamate and furfural are carcinogenic to animals, and have been classified as Group 2A and 3 agents respectively by the International Agency for Research on Cancer. Factors, such as raw materials, process time and storage, affect metal concentrations in beverages. Limits for chemicals and metals in Raki have not yet been established by the Turkish agency. The present study aimed to evaluate the chemical and metal contamination of commercial Turkish Raki. Thirty-seven different types of Turkish Raki were purchased from local markets in Turkey. Ethyl carbamate (EC) and furfural (FR) levels were measured by Gas Chromatography-Mass Spectroscopy (GC-MS). Arsenic, copper, lead, and zinc levels were measured by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). None of the Raki samples contained EC. Furfural was not detected in commercial Raki samples but only in illegal Raki samples. Ethanol and methanol levels complied with Turkish regulation. Our data shows that commercial Raki from Turkey was contaminated by very low amounts of arsenic (<LOD-0.02 mg/L), copper (0.05-0.41 mg/L), lead (< LOD- 0.03 mg/L) and zinc (0.01-0.39 mg/L).

Maleki, Masoud; Manshouri, Negin; Kayikcioglu, Temel
Brain-computer Interface (BCI) systems, usually using signals taken from users' brain through electroencephalography (EEG), control various devices around and provide the user's com-mand by interacting. Improving the quality of life of people with disabilities is the main goal of BCI systems. The importance of BCI-based smart home systems is further increasing as a smart home system directly affects the life of a disabled individual. On the other hand, few BCI systems can be run directly using smart home systems. The importance of the BCI-based smart home and the few existing systems require more work in this vital field. In addition, no reviews have described BCI systems in a smart home. In this study, we reviewed all the papers on BCI-based smart home systems published in the last 6 years. These studies investigated and evaluated BCI systems from nine different perspectives. In addition, all studies were examined in terms of signal processing methods. Finally, the problems and challenges of these systems were discussed and new solutions were pro-posed.

Abstract: This research was intended to determine the effect of different cereal and pulse flours and commercial gluten-free flour on the mineral content, fatty acid composition, and volatile compounds of the gluten-free tarhana (cereal-based fermented dry soup). In order to produce the gluten-free tarhana, white bean (BF), chickpea (CF), commercial gluten-free (GWF), yellow lentil (LF), and rice (RF) flours were used. The Mg, K, Al, and Mn contents of tarhanas obtained using different pulse and cereal flours were found to be quite high compared to tarhanas produced with commercial GWF. The utilization of different cereal and pulse flours in the tarhana formulation resulted in an increase in the percentage (30.37–51.47%) of the total polyunsaturated fatty acid (TPUFA). The highest (452.4 µg/g) and the lowest (241.17 µg/g) total concentration of all compounds were detected in BF and GWF, respectively. The highest number (21) of compounds belonged to terpenes and terpenoids, followed by acids, hydrocarbons, alcohols, aldehydes, esters, ketones, and alkanes. Practical Application: This study shows that cereal and pulse flours can be used to produce acceptable tarhana with improved nutritional quality in terms of mineral and fatty acid contents. The results of the current study may be useful and applicable to food manufacturers producing gluten-free products for celiac patients.

Ökdem, Selçuk; Koşmaz, Betül
With the use of computers in every field, the usage intensity of processors is increasing day by day. In order to cope with this intensity, processors need to be constantly updated and improved. Various scheduling algorithms are being developed every day in order to continuously improve and accelerate the processors and to cope with the processing intensity. The main purpose of the scheduling algorithms is to increase the efficiency of the processor. For this, the processor needs to make a planning between the pending processes. Planning can be done by giving different priorities or using different methods. In order to increase the efficiency of the processor, in this paper, existing algorithms were examined. Round Robin Algorithm was improved using Genetic Algorithm. It is aimed to find the optimum values by selecting the quantum value according to the pending processes and their parameters. When the developed new method compared with the existing standard algorithms, it is observed that the waiting time and the turnaround time were shorter than the other algorithms.

Aim: This study aims to investigate the factors affecting nurses' professional commitment during the COVID-19 pandemic. Background: Commitment to a profession requires doing the best for that profession. In the case of the nursing profession, professional commitment gains greater importance in times of crisis, like the COVID-19 pandemic. Methods: This cross-sectional study was conducted with 389 nurses in the Turkish state hospital. Institutional permissions, ethical approval and written consents from the participants were obtained before carrying out the study. Results: The participants’ mean Perceived Organizational Obstruction Scale score was 20.07 ± 8.06 (min = 5.0, max = 35.0), and their mean Nursing Professional Commitment Scale score was 71.20 ± 11.94 (min = 30.0, max = 103.0). Socio-demographic variables and perception of organisational obstruction predicted 36.7% of the variance in the professional commitment (p <.001). Conclusion: A road map based on the study results was developed for hospitals and nurse managers to maintain and increase nurses' professional commitment. Implications for Nursing Management: The results of this study may help institutions and nurse managers understand the factors affecting professional commitment during the pandemic as a whole, as well as determine primary strategies based on the importance of these factors.

Objective: This study aims to determine the effects of cachexia, causing major problems in the world and Turkey, on self-care agency and quality of life in cancer patients. Methods: The population of this cross-sectional and relationship-seeking study consisted of cancer patients in Turkey from April 1 to April 20, 2021. Using the snowball sampling method, 174 patients were sampled. 'Patient Information Form,' 'The European Organization for Research and Treatment of Cancer C30 Cancer Quality of Life Scale,' and 'Exercise of Self-Care Agency Scale' were used as data collection tools. Results: In the study, 52 patients (29.9%) were found to have cachexia. Function, general well-being, symptom (except insomnia), and self-care agency, which are subdimensions of the quality-of-life scale, were found to be significantly lower in patients with cachexia than patients without cachexia (P < 0.001). It was determined that there was a significant negative correlation between the cachexia status of the patients and the five basic functions in the functional scale (physical, role, emotional, cognitive, and social function), general well-being, and self-care agency, and there was a significant positive correlation between the cachexia status of the patients and the symptom scale (P < 0.001). According to the results of multiple linear regression analysis, it was found that the factor that significantly affected the cachexia status of the patients was their self-care agency (P < 0.001). Conclusions: It was determined that cachexia caused significantly lower self-care agency and quality of life in cancer patients. Furthermore, quality of life was related to self-care agency.

Objectives: This study was carried out in order to determine the prevalence of obesity among the students of the Faculty of Health Sciences and to evaluate the anthropometric measurements of the students. Materials and methods: The population of the study was in total 984 volunteering undergraduate students from Ankara University Faculty of Health Sciences, Child Development, Midwifery, Nursing, Health Management and Social Work departments. The sociodemographic characteristics of the students were obtained with the help of the questionnaire and the anthropometric measurements by the researchers. SPSS package program was used for descriptive statistics, chi-square test and multiple logistic regression analysis for assessment of data. Results: 16.5% of the students participating in the study were overweight and 4.5% were obese. Approximately half of the students who are overweight and obese reported staying in the dormitory. Average BMI value in males is 23.1 kg/m2 and 22.3 kg/m2 in females. 29.1% of females are at risk in terms of abdominal obesity and 30.6% of males in terms of waist/height ratio. Male gender and presence of an obese person in the family increases the risk of being overweight or obese. Conclusions: Risky health behaviors are observed among university students and in order to avoid such behaviors, it is necessary to provide training especially on subjects such as nutrition and physical activity. Adopting the right nutritional habits and healthy lifestyle is important in individuals who will be the future healthcare professionals, for both their and future generations' health.

The aim of this study was to investigate some physicochemical, bioactive, nutritional, and sensory properties of wheat chips enriched with potato peel flour (PPF) at six different concentrations (0, 2, 4, 6, 8, and 10% w/w). Lipid content of the samples were in the range of 45.57-27.46 g/100 g and lipid content of chips decreased (by 40%) significantly (P < 0.05) with the incorporation of PPF. Minimum and maximum hardness levels were 13.32 kg and 22.64 kg, as determined in the control sample and the chips enriched with 8 g/100 g PPF, respectively. Total phenolic of the chips was in the range of 364.7-1108.0 mgGAE/kg and increased significantly (P < 0.05) with increasing of the PPF. In addition, total dietary fiber content of the samples also increased (by 29%) significantly (P < 0.05) by PPF incorporation while the in vitro glycemic index content of samples decreased (P < 0.05). Sensory evaluation revealed that the chips with PPF (by 10%) were more preferred. In this study, alternative chips were produced using PPF.

Bulut, Fatih; Doğru, Aslı; Yaltirak, Cenk; Yalvaç, Sefa; Elge, Murat
We investigated rupture geometry, size, and slip distribution of October 30, 2020, Samos (Sisam)–Kuşadası earthquake combining seismographs, GPS measurements, and SAR analysis. Right after the earthquake, we measured 13 additional campaign-based GPS sites to intensify the available GPS network consisting of 10 continuous stations. We combined all available seismographs to have the best possible accuracy for mainshock and aftershock hypocenter locations. We compiled all available seismic profiles and integrated them using high-resolution bathymetry to map seismically active faults. The mainshock hypocenter is located at 37.913 ± 0.009 N° and 26.768 ± 0.017 E° and a depth of 12.3 ± 1.7 km. Our fault plane solution shows that the mainshock has almost a pure normal-type mechanism. Based on accurate aftershock locations as well as InSAR results, the mainshock rupture is subsegmented with two north-dipping rupture planes. The rupture probably starts on a low angle plane generating 1.1 m average slip between the depths of 9–14 km. It merges to a steep plane at 9 km depth where it generates 1.2 m average slip extending towards the surface near the shoreline of Samos (Sisam) Island. Total size of the two rupture planes and their average slips determine that the magnitude of the mainshock is (Mw ) 6.92 ± 0.02. The mainshock has substantially increased Coulomb stress on several fault segments near the towns Kuşadası and Söke, which have the potentials to generate strong earthquakes. It also nonnegligibly increased Coulomb stress on several fault segments south of İzmir giving a warning for increased earthquake hazard in this highly inhabited area.

Environmental and climate problems have gained a global dimension and constitute one of the important issues of world politics and economies. The necessity of all states to act together on these problems, which threaten the present and future of humanity, and find the solution has revealed the “global” character of the process. The interdependence created by economic development and environmental problems brought a new meaning and dimension to both national and international politics. Especially the recent pandemic has made the global nature of environmental issues more understandable. In this context, it seems necessary to create a work that deals with current debates in the field, which will help identify the problems in the field and find solutions to them.

Çetin, Gökhan; Fadali, M. Sami
This paper presents an optimal bandwidth allocation method for a networked control system (NCS) which includes time-driven sensor, event-driven controller and random channels. A hidden markov model (HMM) with a discretized state space is formulated for the random traffic to predict the network states using a suitable data window. Network bandwidth is allocated based on the predicted traffic state subject to bounds on the deterministic traffic that guarantee acceptable NCS performance and do not exceed hardware limitations. Bandwidth allocation uses l1 minimization of unmet bandwidth demand. A stability condition is derived for a variable but bounded sampling period interval. Computer simulation results show the effect of varying the number of discrete states for the HMM and the window width on bandwidth allocation. The results compare favorably with a published approach based on fuzzy logic.

Kaya, H.; Karaalp, M.; Kaynar, Ö.; Tekçe, E.; Aksakal, A.; Bayram, B.
The study was conducted to determine the effects of stocking density (SD, 5 or 7 layers/cage) and tarragon (Artemisia dracunculus L.) diet supplementation at four levels (0, 1.2, 6 and 12 g/kg feed) on performance, certain egg characteristics, serum, liver, egg yolk and small intestine bacteria parameters in laying hens. The experiment was carried out over a period of 8 weeks, with 192 Lohman Brown commercial hybrids at 50-w-age. The results showed that an increased SD reduced feed intake (FI; p<0.01) and egg production (p<0.05), but had no effect on the weight gain, feed conversion ratio, damaged egg ratio, egg weight and egg quality (p>0.05) parameters. The supplementation of tarragon to the diet reduced the FI and damaged egg ratio (p<0.01), and improved egg production and FCR (p<0.01). While an increased SD reduced serum total antioxidants (p<0.05), it elevated corticosterone (CORT) and total oxidant serum (TOS) (p<0.05). Tarragon was found to enhance total immunoglobulin (p<0.05), but to decreased the CORT and TOS of the serum (p<0.05). An increased SD raised the malondialdehyde (MDA) in the serum (p<0.001), liver (p<0.05) and yolk (p<0.001). Tarragon supplementation reduced MDA of the serum (p<0.05), liver (p<0.001) and yolk (p<0.001). E. coli and total Mesophilic Aerobic Bacteria counts in the small intestine were raised (p<0.001) with increased SD. Tarragon decreased (p<0.05) mesophilic aerobic bacteria. It was thus found that, tarragon supplementation can be considered generally effective in improving performance parameters, alleviating stress-induced negativities, reducing lipid peroxidation, regulating the immune system and controlling some intestinal microorganisms.

Şi̇Şman, Şeyma; Merdan, Mehmet
In this study, the mathematical model (DC) of diabetes disease is discussed. This model divides people into (D) uncomplicated and (C) complex diabetics two. In addition, diabetes is a disease known to be caused by genetic and environmental factors, and this factor is one of the main causes of genetic disorder at birth. Considering these two factors, the diabetes complication (SDC) model, which is sensitive from the diabetes complication (DC) model, is being developed. In this model, the responsive diabetes complication (SDC) model of a nonlinear system of differential equations is transformed into a discrete-time system of equations. The positivity and limitation of Model solutions were examined R0 the basic increment number is calculated. If R0 < 1, it has a global asymptotically stable balance for the situation where there is no genetic disorder at birth, and for R0 < 1, the system has an unstable balance. In addition, random behavior of the discrete model was examined for different probability distributions.
