Yucesan, Melih; Gul, Muhammet; Guneri, Ali Fuat
Gun and rifle manufacturing contain various failures in the process of CNC machining, material supply, research & development, infrastructure and, operator. Due to these failures, the enterprise is exposed to great economic losses and a decrease in competition in the global market. In addition, failures in production cause events that seriously threaten human health. Failure analysis can increase safety by determining the cause of potential errors and taking measures for identified errors in the life cycle of the products. Therefore, this study employs a Bayesian Network (BN)-based modeling approach for capturing dependency among the basic events and obtaining top event probability. Firstly, a fault tree analysis (FTA) diagram is constructed, since its target is to pinpoint how basic event failures result in a top event (system) failure by an AND/OR logical gate. While, AND logical gate should take place in both cases, it is sufficient to realize one of the states in the OR logical gate. Then, a BN-based on fault tree transformation is applied. A case study in a leading weapon factory that produces various types of guns and rifles in the Black Sea region of Turkey is performed. For the application viewpoint, appropriate control measures can be taken into account to decrease the number of failed products based on the performed failure analysis.

Dal, Nursel Alp; Beydağ, Kerime Derya
COVID-19 had negative effects upon family planning. Women cannot visit healthcare facilities because of a fear of curfew-related sanctions or exposure to COVID-19. It is seen that religious beliefs are influential especially in terms of family planning method preference and having abortions. This study was conducted to determine the attitudes of married Muslim women regarding family planning methods during the COVID-19 pandemic period. The descriptive and cross-sectional study was conducted with 611 married Muslim women who presented to the family planning outpatient clinic of a public hospital in Western Turkey between 1 September 2020 and 1 March 2021. The mean Family Planning Attitude Scale score of the women was found to be 137.53 ± 27.11. It was observed that, as the mean age of the women increased, their family planning attitudes were more positive, and as their number of pregnancies, abortions and living children increased, their attitudes were more negative (p < 0.05). Women do not want to get pregnant during the pandemic process. This is because the effects of COVID-19 on both themselves and the baby to be born are not known, which worries women. Therefore, in order to transform positive attitudes regarding family planning into behavior, it is recommended to provide effective training and consultancy services during the pandemic period.

Karakuzu, Ramazan; Djele, Akim; Dogan, Akar
In this study, the effect of ambient temperatures on the punch shear and low-velocity impact behavior of S2 glass fabric and carbon-kevlar hybrid fabric reinforced epoxy composites was investigated. The quasi-static tests (QST) were performed by using a Universal Shimadzu Tensile Testing Machine with various crosshead speeds. Low-velocity impact (LVI) tests were also carried out by using the CEAST Fractovis Plus impact test machine at different impact energies. Flat-nose impactors with a cylindrical punch diameter of 12.70 mm were mounted to the test machines. Both tests have been carried out at various temperatures. After the experiments, the load-displacement, the absorbed energy-impact energy/crosshead speed and punch shear strength graphs are plotted. From the obtained results it can be said that, in penetration cases of low-velocity impact and quasi-static tests, absorbed energy and punch shear strength values show similar behavior for hybrid carbon-kevlar/epoxy at each temperature except for 80 °C while these values are different from each other for S2 glass/epoxy at all temperatures.

Ayçin, Ejder; Kayapinar Kaya, Sema
Zero waste has an important position in the circular economy model in terms of manufacturing recyclable products instead of products to be consumed quickly, reducing the amount of waste, developing and implementing recycling/reuse technologies, and thus ensuring resource efficiency. A zero-waste strategy is one of the basic steps to achieve the goal of the circular economy. The number of studies conducted on Turkey’s zero waste management strategies referring to the circular economy is quite limited. To fill this gap in the literature, this study aims to identify the potential barriers which have an important role in zero waste management practices in Turkey. Through a broad literature review and expert opinions, 12 key barriers for zero waste implementation in Turkey have been defined in view of circular economy principles. Then, fuzzy DEMATEL methodology is employed to examine which is the most influential barrier affecting zero waste management success and to identify the interdependence of these barriers. The results indicate that uncertainty of the goals and tactics relevant to the circular economy and lack of financial and economic aid are key causal barriers that affect Turkey’s zero waste management.

Aslan, Alper
The purpose of the study is to investigate the effect of first aid training in live online classes using the problem-based learning approach on students' learning achievement, problem-solving skills, communication skill, and interaction. The pre-test and post-test quasi-experimental design with a control group was used in the quantitative dimension of the study. The study group was conducted with forty-five university students. While live online classes in the experimental group were carried out via the PBL approach, live online classes in the control group were traditionally carried out via teacher-based methods without any intervention. Zoom application was used in both groups during live online classes. Group work in the experimental group was conducted using breakout rooms. The process of data collection and the experimental procedure of the study was completed in six weeks. Within the scope of the study, courses took three 40 min periods every week. The Learning Achievement Test, the Perceived Problem-solving Skills Scale, the Communication Skills Scale, and the Online Course Interaction Level Determination Scale were used for data collection tools. The results of study show that students who attended live online classes using PBL had higher levels of learning achievement, problem-solving skills and live online class interaction than students who attended live online classes using teacher-based methods. No significant difference between the communication skills of the groups was observed.

Polat, Alper
In this study, continuous contact problem in the functionally graded (FG) layer loaded with a FG flat punch resting on the elastic semi-infinite plane was analyzed by the finite element method (FEM). It was assumed that the shear modulus and density of the layer and punch varied according to exponentially throughout their depth. FG layer's weight was included to the problem and additionally all surfaces were considered as frictionless. Analysis of FG materials was performed with a special macro which was added to the ANSYS program. Firstly, the shear modulus of the punch was considered to be very rigid and the results of initial separation load (λcr) and distance (xcr) were compared with the analytical solution. Afterwards, results obtained from the contact analysis made according to the inhomogeneity parameters (β, γ) between FG punch-FG layer which had been unprecedented in the literature were discussed. As a result, FG punch's stress values at the punch edges where stress accumulations occurred were found to be smaller than the rigid punch. The security of the structure, longer life of the material and ease of production are directly related to the reduction of the stress values. The results obtained in this study are important in this respect. Also this work is the first study that investigates the effect of FG punch on the FG layer.

Omaç, Zeki; Cevahir, Ceren
Switched reluctance generators (SRGs) come into prominence in other electrical machines with its simple structure, only stator winding, reliability, high fault tolerance and the possibility of working within wide speed range. These generators are used especially in wind power plants due to their ability to operate in variable speed range and applications of aviation and electric cars. In this study, the control of the SRG was performed. A simulation of SRG driver in Matlab/Simulink was performed and the real-time implementation control of SRG is carried out on DS1103 Ace kit digital signal processor to determine the performance of the SRG. The output voltage of the SRG is controlled by the proportional-integral (PI) voltage controller. As a result, the graphs of change in SRG phases currents and SRG output voltage were obtained according to different parameters. Simulation results compared with experimental results. Consequently, they overlap on experimental results.

The aim of this study was to investigate the possible protective effects of chrysin on oxidative status and histological alterations against carbon tetrachloride (CCl4)-induced liver and kidney tissue in rats. The animals were randomly divided into four groups; the control, chrysin (100 mg/kg), CCl4 (0.5 ml/kg) and chrysin + CCl4 groups. Liver and kidney injuries were assessed by biochemical and histopathological examinations. The levels of malondialdehyde (MDA), reduced glutathione (GSH), and superoxide dismutase (SOD) activity were measured in tissues. Serum tumor necrosis factor-α (TNF-α), aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, and creatinine levels were also measured in blood samples. MDA, serum TNF-α, AST, ALT, urea, and creatinine levels (p < 0.05) were significantly higher, and SOD activity and GSH level were significantly (p < 0.05) lower in the CCl4 group than in the control group. Treatment with chrysin in the chrysin + CCl4 group decreased MDA, AST, ALT, creatinine, and TNF-α levels (p < 0.05), and increased SOD activity, GSH levels (p < 0.05), and serum TNF-α levels (p < 0.05). In addition, body weight change (BWC) (p < 0.05) and feed intake (FI) were significantly lower (p < 0.001) in the CCl4 group than in the control group. Moreover, treatment with chrysin increased BWC and FI in the chrysin + CCl4 group compared with that in the CCl4 group. These findings also confirmed by histopathological examination. The chrysin treatment ameliorated the CCl4-induced biochemical and pathological alterations. These results demonstrated that chrysin provided amelioration on the rat liver and kidney tissues CCl4-induced injury by increasing the antioxidant activity.

Kocabaş, Mehmet; Kutluyer, Filiz; Çakir Sahilli, Yeliz; Aksu, Önder
Plastics are one of the global environmental problems owing to their highest production. Bisphenol A (BPA) is used in the manufacturing of plastics including polycarbonate, polyvinyl chloride and resins. In particular, aquatic ecosystems are adversely affected by the occurrence of micropollutants. In addition, BPA as a typical endocrine-disrupting chemical (EDC) seriously influences androgenic activity and reproduction of aquatic organisms, particularly fish as non-target organism. In toxicological assays, sperm cells can be used as a potential tool for reliable and practical assessment. For these reasons, sperm cells were exposed to lower concentrations (0 µg/L, 0.5 µg/L, 1.25 µg/L, 2.5 µg/L and 5 µg/L) of BPA and the study focused on BPA-induced oxidative stress. The enzymatic [glutathione peroxidase (GSH-Px), catalase (CAT) and superoxide dismutase (SOD)] activities and lipid peroxidation (MDA) were analyzed in spermatozoa. The study findings showed that the activities of SOD and GSH-Px were significantly decreased by BPA but lipid peroxidation (MDA) and CAT acticity increased. Notably, the percentage and duration of motile sperm cells decreased. Collectively, spermatozoa clearly showed the sensitivity even at extremely low concentrations. This is first report to assess the impact of BPA on sperm cells of spirlin Alburnoides bipunctatus.

Aydin, Alp Bugra; Baylar, Ahmet; Ozkan, Fahri; Tuna, Muhammed Cihat; Ozturk, Mualla
When the gate of a high-head conduit is partly opened, negative pressure draws the air in through the air vent. Air that is entrained into the water is instantly forced downstream in the form of air bubbles. When studies on high-head gated conduits were examined, it was determined that the air demand ratio varied depending on many hydraulic and geometric parameters. This work has focused on determining the effect of conduit cross-section geometry on the air-demand ratio. A series of experiments were carried out on high-head radial gated conduits having different cross-section geometries. Experimental results showed that conduit cross-section geometry had an important effect on the air demand ratio especially in small gate opening rates. Further, design equations for the air demand ratio are presented relating the air demand ratio to Froude number, gate opening rate, and the ratio of gate opening to conduit length.

This qualitative study aims to examine teachers’ opinions concerning the middle school curricula that have been in use for years, in order to determine its suitability for distance education during the COVID-19 pandemic. The participants consisted of eighteen middle school teachers from different subject areas in Turkey. A maximum variation sampling method was employed for participant selection. The data was collected through semi-structured interviews. Due to the pandemic, the interviews were conducted using video conferencing applications. The data was analyzed through content analysis. According to the findings, the teachers report that while they are effective in achieving cognitive objectives, they have difficulties in achieving affective and psychomotor objectives. In addition, the teachers do not prefer to design their own materials, rather they mainly benefit from ready-to-use materials during emergency distance education. The teachers also reveal that direct instruction and questioning were the teaching methods and techniques they preferred in online courses and that they were unable to adapt other methods and techniques to distance education, which resulted in students experiencing teacher-centered activities. Moreover, the teachers complain about students not attending the online courses on time or even at all, their disinterest, a lack of instant feedback, limited communication with students, and insufficient course lengths. Another critical finding was that the teachers only use homework, end-of-unit quizzes, and participation to online courses as measurement and evaluation tools and agree that they are unable to administer reliable and valid evaluation tools. The limitations of the study and implications for future research are later discussed.

The reuse of industrial waste materials in cement-based composites contributed to preventing increasing environmental problems and reducing production costs. This article examined the effectiveness of using recycled steel chips (Ast) from metal industry waste and waste marble powder (BMP) instead of cement and the possibility of obtaining eco-efficient specimen. While steel chips included in mortars as additives decreased workability, marble powder increased it. An increment in the level of substitution of steel chips resulted in a subsequent increase in water absorption percentages and apparent porosities of mortars. Maximum flexural strength was obtained in 2% steel chips-10% marble powder in waste system.

The lack of ethnoveterinary surveys in Turkey, results in losses in the veterinary phytopharmacology field. This is the first ethnoveterinary research in which statistical calculations about plants are done by informant consensus factor (ICF) method in the Blacksea Region of Turkey. To catalog, analyze, and disseminate the knowledge of plant use in ethnoveterinary practices in the province of Giresun (Turkey). Information was gathered through open and semi-structured interviews with local people, mainly elderly shepherds and farmers, in the Giresun province. The collected data was analyzed quantitatively using two indices, informant consensus factor (ICF). A total of 65 ethnoveterinary plants belonging to 38 families are used for the treatment of animal diseases. According to the local farmers, the most often mentioned species that used in the resarch area have high ethno-veterinary potential. Most of these plants are also used for some human conditions in the study area. There are large numbers of ethno-veterinary practices EVPs in southern Turkey with undocumented cumulative knowledge of the indigenous people. Unfortunately, some evidence of their slow disappearance has been found. The traditional knowledge in the treatment of livestock diseases of the Giresun districts needs further scientific evaluations by phytochemical and antimicrobial experimentation.

The leaching behavior of Tunceli smithsonite ore in nitric acid was evaluated in two study steps including optimization of leaching process and kinetics modeling. The individual and synergistic effects of effective parameters such as nitric acid concentration, solid-to-liquid ratio, stirring speed, and temperature on the dissolution rate of zinc were investigated using central composite design. Four factors including temperature (30–50 °C), nitric acid concentration (0.2–0.5 mol/L), stirring speed (350–600 rpm), and solid-to-liquid ratio (0.004–0.01 g/L) were investigated. The dissolution percent of zinc (97%) was obtained in 120 min of leaching time: acid concentration 0.5 mol/L, temperature 50 °C, stirring speed 500 rpm, and solid–liquid ratio 2/500 g/mL at the optimum conditions obtained using the central composite design. The dissolution kinetics of smithsonite was examined according to heterogenous models and it was found that the dissolution rate was controlled by ash layer diffusion process. It was found that the leaching rate increased with increasing temperature, stirring speed, and acid concentration as well as decrescent particle size and solid/liquid ratio. The trial data were analyzed by statistical and graphical methods and the activation energy of this leaching process was determined to be 28.63 kJ·mol−1.

Gümüşsoy, Süreyya; Dönmez, Sevgül; Ekşi, Ali; Dal, Nursel Alp
Background: Domestic violence, specifically, violence against women, is prevalent in all segments of society regardless of social class, ethnicity, culture or country. In other words, domestic violence is a global concern. Aim: The study aims to investigate the relationship between the attitude and knowledge of the health staff in pre-hospital emergency medical services about violence against women and their recognition of such form of violence. Methods: This descriptive study was conducted on 1023 paramedics and emergency medicine technicians who work in the pre-hospital emergency health setting and are members of the Paramedic and Pre-hospital Emergency Medicine Association. The Attitudes towards Violence against Women Scale (ATVAWS) and Health Staff's Recognition of Signs of Violence against Women Scale (HPRSVAWS) were used for data collection. Results: The mean scores for the ATVAWS and HPRSVAWS were 46.68 ± 6.92 and 20.31 ± 3.23, respectively. Of the participants, 48.5% had been subjected to violence, 43.93% had been subjected to violence perpetrated by their mothers, 41.53% had been exposed to physical violence and 4.2% remain exposed to domestic violence. Participants who had been exposed and those who remain exposed to domestic violence produced high scores in ATVAWS, which indicates an improvement in the traditional approach (less opposing view) to violence. High scores in the ATVAWS for (a) those who were exposed to violence in their workplaces, (b) who had never attended to actual or suspected cases of violence against women in their professional life, (c) who had attended to seven or more cases of violence against women, (d) who were less competent in physically examining actual or suspected cases of violence and (e) who had not been trained on violence against women, which indicates an increase in the traditional approach to violence. Conclusion: The study found that health staff in emergency health stations better recognised the signs of violence against women as their attitudes towards violence were less similar to the traditional approach. That is, they mostly held non-violent views. The characteristics, attitudes, perceptions and values of health professionals were considered important factors in addressing violence.

Unal, Asuman; Hillman, A. Robert; Ryder, Karl S.; Cihangir, Salih
Although the World Health Organization (WHO) recommends a limit of 1.5 mg l-1 fluoride ions in drinking water, this is not satisfied in many parts of the world. When this limit is exceeded, the electrochemically switched ion-exchange (ESIX) technique (mainly based on conductive polymers) has been identified as a promising method for removing the excess fluoride ions. The present study aimed to develop an efficient method based on the ESIX technique by using poly(aniline-co-o-aminophenol) copolymer to extract fluoride ions. Electrochemical quartz crystal microbalance (EQCM) and acoustic admittance data were utilized to assay the synthetic efficiency of copolymer deposition, and to evaluate the dependence of the defluoridation process on the proportions of the monomers in the copolymer matrix and on film thickness. The resulting films were characterised by Fourier transform infrared spectroscopy (FTIR) and scanning electrochemical microscopy (SEM) techniques. For optimized co-monomer ratio in the feedstock, poly(aniline-co-o-aminophenol) at an applied potential of 0.30 V showed excellent performance for fluoride removal from water at pH 6.6, to the extent of 20 (mg F-) (g polymer)-1. Comparison of the performance of ESIX using poly(aniline-co-o-aminophenol) with that of other techniques and materials reveal that it has significant potential for water defluoridation.
