    Grains and Pulses in Diets of the Middle East and a Focus on Buckwheat

    Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih

    Buckwheat (Fagopyrum esculentum Moench and Fagopyrum tataricum (L.) Gaertn.) is believed to have originated in central Asia. Chiefly cultivated in India, Nepal, China, North Korea, Russia, and Japan, it is a pseudocereal containing high protein, dietary fiber, vitamins and minerals, polyunsaturated fatty acids, and important antioxidants and phenolic compounds. In addition to its high protein bioavailability and economic value, it is an important alternative food with high nutritional value, suitable for the diet of celiac patients because it does not contain gluten. Buckwheat has gained worldwide importance because of the presence of some important bioactive constituents such as rutin, orientin, vitexin, quercetin, isovitexin, and isoorientin; other essential components like fagopyritols find vast potential for glycemic control in type 2 diabetics, positive cardiovascular effects, treatment of celiac disease, prevention of gallstones, and several hormone-dependent tumors. Currently, various products of buckwheat like flour, bread, biscuits, cookies, muffins, cakes, pasta, noodles, crackers, chips, and various fermented products and desserts are available in the market. Buckwheat has attracted worldwide attention, especially from food scientists, for its healing effects over chronic diseases. This chapter focuses on buckwheat in diets of the Middle East and its important effects on health.

    Islamic Law Challenges in Addressing Human Trafficking and Sexual Exploitation

    Insani, Nur; Karimullah, Suud Sarim; Sulastri

    Human trafficking and sexual exploitation remain complex global problems. Islamic law, as one of the legal systems in the world, has a strategic role in participating in overcoming this problem. However, the Islamic legal norms implementation requires support from the state and society. This research discusses the strategic role and challenges of the law in overcoming human trafficking and sexual exploitation. The research method used normative Islamic law with a philosophical approach. The analysis technique used prescriptive analysis, with the analysis process using Islamic legal reasoning. The research results show that Islamic law has a strategic role in resolving the problem of human trafficking and sexual exploitation. The argument is that, philosophically, Islamic law emphasizes the importance of maintaining human honor and dignity, while theoretically, Islamic law recognizes two main concepts in punishment, namely hudud and ta'zir. Hudud is a punishment determined by Allah and has clear rules in the Quran and Hadith. Meanwhile, ta'zir is a punishment determined by a judge for the benefit of society. The challenges of Islamic law in overcoming human trafficking and sexual exploitation are a lack of understanding of Islamic legal norms, which requires human values and justice; Islamic law is not implementable; and there is a perception that the principles of Islamic law can only be applied in Islamic countries. Therefore, global Muslim countries and communities are the main actors in maximizing the application of Islamic legal principles in overcoming human trafficking and sexual exploitation.

    Excessive groundwater withdrawal and resultant land subsidence in the Küçük Menderes River Basin, Turkey as estimated from InSAR-SBAS and GNSS measurements

    Yalvaç, Sefa; Alemdağ, Selçuk; Zeybek, Halil İbrahim; Yalvaç, Murat

    Küçük Menderes River Basin (KMRB) is located in the western part of Turkey in the city of İzmir. The basin hosts about half a million people and 90% of the population makes their living from farming and animal husbandry. Most of the water needs for agricultural irrigation, animal husbandry, and drinking are met from groundwater resources in the basin. Since the water pumped from the aquifers cannot be naturally recharged by surface waters and precipitation, the groundwater level is rapidly receding and a decrease of up to 150 meters has been observed in the historical groundwater level time series since the 1990s. For this reason, land subsidence occurred in the basin and as a result of this, crustal surface cracks have formed and infrastructure and superstructure facilities have been endangered. To prevent loss of life and property that may occur in the future, it has become necessary to estimate the magnitude and the expansion zone of the land subsidence by carrying out geodetic monitoring studies in the region. In this study, the analyzes performed by Interferometric Synthetic Aperture Radar-Small Baseline Subset (InSAR-SBAS) and Global Navigation Satellite System (GNSS) methods to monitor land subsidence in the KMRB are presented. For this purpose, monthly 74 SAR images from 2017 to the end of 2022 were evaluated according to the SBAS procedure in the GMTSAR academic analysis software. In order to, both validate the InSAR-SBAS results and convert the deformation rate in the Line of Sight (LOS) to the ellipsoid normal direction, 3 periods of GNSS campaign were performed between 2021 and 2023 in 5 different GNSS stations and evaluated with the GAMIT/GLOBK software. According to the analyses, the land subsidence rate of up to −165 mm/year has been estimated in the KMRB, especially in the district centers of Bayındır and Ödemiş. In addition, unlike many studies, different rates and propagation of subsidence were determined in different parts of the basin depending on the aquifer type and precipitation. Monthly time series of the deformations were created and the behavior of the deformations and its relationship with the groundwater withdrawal and the lithological structure in the region was scrutinized. Thus, the spatio-temporal behaviour of the land subsidence and the associated geological factors were revealed.

    HOW PRO-ENVIRONMENTAL AND SAVING BEHAVIOURS DETERMINE ORGANIC PRODUCT AND SECOND-HAND PRODUCT PURCHASE INTENTIONS: A STUDY IN TURKEY; [Kako prookolišno i štedljivo ponašanje određuju namjeru kupnje organskih i rabljenih proizvoda: istraživanje u Turskoj]

    Avci, Ibrahim

    The study focuses on sustainable consumption, which has recently gained popularity. The study seeks to ascertain the effects of pro-environmental behaviour and saving behaviour, both of which are constructs of sustainable consumption behaviour, on the organic and second-hand product purchase intention. Convenience sampling method was used in the collection of data, in which any consumer could participate, and the data were collected with a prepared online questionnaire. According to the findings of the study conducted on 595 Turkish consumers, pro-environmental behaviour and saving behaviour have positive effects on second-hand product purchase intentions, while pro-environmental behaviour has a positive effect on organic product purchase intention and saving behaviour has a negative effect on it. These findings make significant contributions to the literature and practice of sustainable consumption.

    Understanding university students WHO do not want to volunteer in disasters: A qualitative study from Türkiye

    Demirbilek, Ömer; Öztürk, Serkan

    A functional and sufficient volunteer community is needed to reduce the damage of disasters and to have a rapid response and recovery process. Most of the volunteering studies in disasters in the literature focus on the positive side of the volunteering process, but there are many negative points that prevent individuals from volunteering in disasters. In this research, it is aimed to discover why university students, who are one of the most valuable groups in volunteering in disasters, do not volunteer in disasters. The research was conducted with a phenomenological design. Maximum variation and criterion sampling were used to decide the study group. The study group consists of thirteen university students with distinctive characteristics. The interview method was used as the data collection technique, and the semi-structured interview form developed by the researchers was used as the data collection tool. Thematic analysis was conducted with the MAXQDA 2020 qualitative analysis program on the obtained data. As a result of the data analysis, seven themes appeared, consisting of İnformation, Economy, Interpersonal Bonds, Uncertainties, Individual Characteristics, Perceptions of Volunteering, Promotion and Advertising Activities. Finding the negative aspects of volunteering that distracts young people from volunteering will be one of the best preparations for future disasters.

    Recoil Stabilization of Two-Wheeled Robot Through Control Moment Gyroscope (CMG)

    Unker, Faruk

    In this study, the weapon and gyroscopes mounted on the armored two-wheeled robot have been studied for controlling recoil dynamics. To date, the interaction between recoil energy and control moment gyroscope (CMG) has not been investigated for a two-wheeled robot. Therefore, this study will be interesting academic research in the dynamic response and control strategy of a CMG subjected to recoil impulsive loads resulting from firing the weapon. The first aim of this study is to maintain the stabilization of the robot within the CMG limits when subjected to impulsive loads without needing the allowable stroke as being for a hydraulic damper. Equations of motion and the correlation between the shot recoil and angular momentum are derived by the Lagrangian method and simulated by Matlab. Then RecurDyn model of the two-wheeled robot is used to control and analyze dynamic parameters under applied recoil energy. As a result, the comparison of RecurDyn simulation and Matlab data are extremely exact and the Lagrangian equations can be used to obtain optimal parameters of the two-wheeled robot concerning the correlation between gyroscopes and weapon.

    IMPORTANCE OF STATIC TESTS FOR THE PREDICTION OF AMD POTENTIAL OF CEMENTED PASTE BACKFILL

    Cihangir, Ferdi; Koc, Ercument; Orak, Mursel; Deveci, Taha Yavuz; Ercikdi, Bayram; Trofymchuk, O.; Rivza, B.

    Cemented paste backfill (CPB) is an engineering mixture of mine tailings, cement and water. Tailings can commonly contain sulphidic minerals. In this case, acid mine drainage (AMD) may occur due to the oxidation of sulphidic minerals present in the body of the CPB. In general, AMD lowers the pH of the medium and water environment and may cause heavy metal release. Therefore, AMD potential is an important parameter to be considered with regard to environmental aspect. Static tests are widely used to determine the AMD potential of sulphidic materials. When neutralization capacity is higher than the acid generation potential, tailings can be safely stored from an environmental point of view. In this study, AMD potential of CPB material produced from sulfur-containing fine tailings is investigated. In this scope, a static modified ABA test was performed on fine sulphidic tailings (TA) and CPB produced from the same sulphidic tailings+7%wt. SR5 cement+water for the first time. Findings suggests that the CPB material had a lower AMD potential (~10%) compared to the tailings. Acid generation capacity of both tailings and the CPB was found to be dominant due to the high sulphide content (~30%wt. and ~28%wt.), respectively. However, CPB was observed to maintain its structural integrity and did not release acidic water for at least 40 weeks. This study showed that a well-designed CPB can be effectively used as an environmentally friendly mine tailings management method.

    Sirat, Abdulveli

    There is need to breed wheat cultivars that are important in human nutrition with high seed yields and improved quality in terms of consumption. This study was conducted at Gumushane-Siran (Turkey) during the 2016–2017 and 2017–2018 cultivation seasons (winter) to identify bread wheat cultivars that show superior performance in terms of seed yield and quality characteristics. This research included 20 bread wheat cultivars using three replications based on the randomized complete block design. Heading date, plant height, spike length, number of seeds per spike, grain weight per spike, seed yield, and some quality characteristics (thousand seed weight, hectoliter weight, protein percentages, Zeleny sedimentation, and wet gluten percentage values) of cultivars were investigated. The maximum seed yield was obtained from Canik 2003 cultivar with 3749 kg ha−1, the lowest seed yield was noted as 3032 kg ha−1 in the Mufitbey cultivar. However, Canik 2003 cultivar came to the forefront in terms of spike length, number of seeds per spike, grain weight per spike, hectoliter weight, thousand seed weight, protein percentages, Zeleny sedimentation, and wet gluten percentage. In the cultivars included in the experiment, it was determined that there were positive and significant correlations between seed yield and number of seeds per spike, thousand seed weight, hectoliter weight, wet gluten percentage value, grain weight per spike, and protein percentages. The results showed that Canik 2003, Ekiz, Goksu-99, Karahan-99, and Selimiye come to the fore in terms of yield and yield elements and quality characteristics, and it seems appropriate to recommend.

    Identification of the drivers of and barriers to COVID-19 vaccine intake behavior using a mixed-method design: implications from a developing country

    Kordestani, Arash; Oghazi, Pejvak; Izmir, Onur; Oypan, Oguz; Ozer, Serhat

    Various COVID-19 vaccines are available across the world. However, short phases of clinical trials for emergency use and myriad rumors about and misinformation on vaccines spread through different media sources, induce confusion and trigger vaccine hesitancy behavior. Although clinical trials demonstrated promising results in the ability of vaccines to protect, social endeavor is required for vaccines to succeed. Mitigation of the pandemic is only possible through widespread acceptance of the vaccine. Thus, identifying the factors that impact vaccine intake is crucial. This study determined factors that affect intentions toward vaccination using a mixed-method approach, in which qualitative and quantitative analyses were conducted together. Analysis of variance (ANOVA) is used in the quantitative study, and content analysis is employed in the qualitative study. The final sample of this mixed-method study consists of 568 participants for the quantitative study and 237 for the qualitative study. They were selected using an online questionnaire. Findings suggest that social, psychological, attitudinal, perceptual, and informational factors play a crucial role in shaping people's intentions toward vaccines, ultimately influencing their decision to accept or reject vaccination. Results of both the qualitative and quantitative studies, in parallel with each other, indicated similar barriers against and drivers toward vaccine intake behavior, providing strong insights into the reasons behind vaccine acceptance and hesitancy. Based on the insights gained in this study, a set of recommendations were compiled for policymakers.

    2D and 3D Numerical Simulation of Dam-Break Flooding: A Case Study of the Tuzluca Dam, Turkey

    Akgun, Cagri; Nas, Salim Serkan; Uslu, Akin

    Unlike river floods, floods caused by dam breaks occur much more abruptly and at higher water velocities. The failure of a dam due to any reason can pose a significant threat to settlements in the downstream area due to the high volume of water in its reservoir. In this case study, 2D and 3D numerical failure simulations of Tuzluca Dam, to be built in the Igdir province of Turkey, was performed using the Flow3D Hydro software. The Shallow Water and Reynolds-Averaged Navier-Stokes (RANS) equations were used to simulate flood propagation. In the numerical models, RNG k-ε was chosen as the turbulence model. In the analyses carried out under different scenarios, it was observed that in both methods (2D and 3D), significant flood depths would occur in two downstream village settlements. Within the scope of the study, the mortality rates in different dam-break scenarios of the Tuzluca Dam were also investigated. It has been observed that the dam failure time and breach geometry have a significant impact on the flood propagation and the loss of life in settlements. Additionally, a dam-break experiment in literature dam-break experiment was numerically solved using the Flow3D Hydro software to validate the numerical model, and a satisfactory harmony was observed between the experimental results and the numerical models. Although the 3D analysis provided a more accurate representation of the experimental results, it took approximately 20 times longer to complete the dam failure simulation in the case study compared to the 2D model. As a result, it has been determined that for comprehensive studies such as those of dam failures, 2D analyses may be more practical, while for smaller-scale scenarios or situations requiring greater precision, 3D modelling is appropriate.

    The epiphytic bryophyte succession of Buxus sempervirens forests in the Fırtına Valley, Rize (North Türkiye)

    Ezer, Tülay; Alataş, Mevlüt; Batan, Nevzat; Erata, Hüseyin

    In this study, the epiphytic bryophyte succession of the Buxus sempervirens L. forests in Fırtına Valley (Çamlıhemşin-Rize, North Türkiye), one of the nine biodiversity hotspots in Türkiye, was investigated. For this pur-pose, a total of 60 sampling plots were taken from the live trunks of B. sempervirens trees of different ages. Twenty-nine epiphytic bryophyte species were determined (24 mosses and 5 liverworts) within the sample plots. Also, six different life form types and four different habitat affinity categories were determined. Among them, the mat type life form is in first place with 34.4% and the cortico-saxicolous species are the most common with 51.7%. Two-way indicator species analysis (TWINSPAN) classified the epiphytic bryophyte communities on B. sempervirens trunks at the second level into two main clusters (A and B) and three sub-clusters (A1, B1 and, B2). Detrended correspondence analysis (DCA) axis 1 was interpreted as gradient along the height of the epiphytic habitat (from the lower base to the upper zone) on trunks and the DCA axis 2 was interpreted as gradient of moisture (from mesic to xeric). Exsertotheca crispa (Hedw.) S. Olsson, Enroth & D. Quandt was the species with the highest index of ecological significance (IES) value on the lower bases of the aged trees. Species diversity and epiphytic cover in the upper zones were lower than in the basal and middle zones in the study area. While Metzgeria furcata, (L.) Corda, Oxyrrhynchium hians (Hedw.) Loeske, Plagiothecium nemorale (Mitt.) A.Jaeger, and Radula lindenbergiana Gottsche ex C.Hartm were only found on old trees, Ctenidium molluscum (Hedw.) Mitt. and Pseudoleskeella nervosa (Brid.) Nyholm were only found on middle-aged trees.

    Teacher education is a critical component of the educational system, as it provides the skills and knowledge necessary for effective instruction in science and other related subjects. The purpose of this research is to enhance the incomplete and incorrect knowledge and skills of science teachers related to the formation of seasons by using a physical model that reveals the “change in the amount of energy per unit surface (CAEUS)”. Twenty-nine teachers from different regions of the country conducted experimental studies with physical models related to the formation of seasons, as part of a 5-day training program that included topics on astronomy. In this study, in which descriptive statistics, inferential statistics, and thematic analysis were used, it was observed that the comprehension of the causes and effects of the change in the amount of energy per unit surface was very successful in the development of mental models for understanding the seasons. Furthermore, the teachers reported that they were able to use the knowledge and skills they gained from the program in their teaching practice. The results obtained were compared with the literature and interpreted accordingly.

    Spirituality management in the workplace: New strategies and approaches

    Özsungur, Fahri; Bekar, Fevziye

    In recent years, after realizing that personal beliefs and spiritual development are as important as mental strength, studies in the field of spirituality in the workplace have grown exponentially. The experts here provide conceptual frameworks and guidance by examining the subject in the light of current developments at multiple levels of analysis: individual, organizational, cultural, and in leadership. Furthermore, this book focuses on rapidly evolving business models: remote working, the cyber-workplace, social media, digitalization, etc - all accelerated by the COVID-19 epidemic. The concept of spirituality in the workplace can be harmful as well as beneficial. Employees who are spiritually attached to the workplace may ignore issues known as 'organizational deviation' (such as theft and corruption) by keeping the interests of the institution in the foreground. These 'dark' and 'invisible' aspects of spirituality in the workplace are also examined, with a special focus on identifying aspects of spirituality which can harm businesses. Spirituality in the workplace considers employees as a whole, in spirit, body, and mind.

    Detection of pneumonia from pediatric chest X-ray images by transfer learning

    Demir, Yasin; Bingöl, Özkan

    When pathogens such as viruses, bacteria and fungi attack the lungs, the alveoli fill with inflamed fluid, causing pneumonia. Early diagnosis of this disease, which has fatal outcomes especially in children under 5 years old, is very important in controlling undesirable situations. Chest X-ray images play an important role in the diagnosis of pneumonia. In addition, the fact that the amount of radiation is lower than imaging devices such as tomography and the possibility of being accessible even from rural areas creates an advantage for X-ray devices. However, X-ray images that are not always clear or human conditions such as fatigue and lack of attention can make it difficult for specialists to detect pneumonia. In this study, a transfer learning-based convolutional neural network (CNN) approach is proposed, which can help specialists in the early and accurate diagnosis of pneumonia in children and, classify healthy and diseased individuals through Chest X-ray images. As a result of the study, an original CNN was proposed by adding additional layers to the AlexNet architecture layers and a test accuracy of 96.31% was obtained.

    Institutional Quality and Unemployment in OECD Nations: A Panel Causality Test Using a Fourier Function

    Cicen, Yildirim Beyazit

    A significant impact of institutional quality on sustainable growth has been revealed in recent studies. This study aims to examine the relationship between different institutions and their unemployment rates, considering the legal system and property rights index. A novel and robust panel Fourier causality test was conducted to investigate 38 OECD nations for the relationship between their institutional quality and unemployment rates between the years 2000 and 2018. Regardless of stationarity, the adopted method allowed for the endogenous identification of structures, locations, and forms, and the evaluation of causal relationships. In addition, the Fourier method and the trigonometric terms were used for analyzing the structural changes. According to the findings, a unidirectional causal relationship existed between the quality of the legal system and property rights and the unemployment rates in the investigated nations during the relevant period. In addition, bidirectional causality existed between the variables in Germany and the United States. It is therefore recommended to necessarily improve a nation’s institutional structure to reduce its unemployment rate. Low unemployment rates would be achieved by improving institutional quality, particularly in developing nations. Therefore, policymakers must focus on formulating policies to reduce unemployment in the long run, considering the legal system and property rights of the nation.

    Exploring managerial insights through multi criteria decision making techniques in pharmacy inventory classification problem

    Şimşek, Ahmet Bahadır; Göktekin, Zekiye; Geliç, Büşra

    The current research addresses the inventory classification problem of community pharmacies, which have a dual role as both a vital component of the pharmaceutical supply chain and a typical retail store. Despite the existing literature indicating that pharmacists may lack knowledge on inventory management, it seems that the MCIC literature is weak in explaining how pharmacists can benefit from MCDA techniques in all aspects. To bridge this gap, the study aims to demonstrate that pharmacists can utilize MCDA techniques to gain deeper insights beyond mere classification in the context of inventory management. Real-world data from a community pharmacy in Turkey was classified using the EDAS method. Sensitivity analysis was performed for MCDA inputs, about which pharmacists may lack information. Scenario findings based on criterion weights and threshold values offer important managerial implications for pharmacists. This study provides a critical contribution to the literature on inventory management in community pharmacies by highlighting the potential of MCDA techniques to support decision-making beyond mere classification. The sensitivity analysis also sheds light on areas where pharmacists may lack knowledge and suggests ways to address these gaps. Overall, the study underscores the need for pharmacists to have a deeper understanding of inventory management and highlights the potential benefits of MCDA techniques in addressing this challenge.

    The Effect of Different Physical Education Class Hours Applied in Secondary Education on Certain Physiological and Physical Parameters

    Sever, Mehmet Onur; Söyler, Mehmet; Çingöz, Yunus Emre; Barkin, Emrah

    This study investigates the effects of different physical education lesson hours applied to secondary school students on some physical and physiological parameters. A total of 36 secondary school students voluntarily participated in the study: respectively, 18 from Group 1 and 18 from Group 2 (age: 14.94±0.41 / 14±0.34 years; height: 175.22±7.62 / 169.33±6.95 cm; weight: 61.95±9.07 / 56.83±6.33 kg). While Group 1 students received 8 hours of physical education lessons per week, Group 2 students were given 2 hours of physical education lessons according to the Ministry of National Education curriculum. Body weight (kg) and body fat percentage (%) were determined using the Inbody 270 professional body analysis device. A portable dynamic balance device was used to determine the students' balance. The test results were analyzed using the SPSS Statistics software. Non-parametric tests were employed since the data did not show a normal distribution. The Mann-Whitney U test was used to test the significance of the difference in balance and body fat percentage (BFP) level averages between the two independent groups. Upon evaluating our data, it was statistically ascertained that the dynamic balance (Balance) values of Group 1 secondary school students were significantly higher when compared to Group 2 students. However, no statistically significant difference was found in body fat percentage (BFP) values between Group 1 and Group 2. As a result, it is seen that increasing physical education lesson hours in secondary education contributes to some physical development of young individuals.
