Mızrak, Sefa; Turan, Melikşah
People may have to leave their home, environment, region and country because of disasters or disaster risks. Effective and efficient disaster risk reduction activities involving the community can reduce disaster risks and enable people to reside more safely and peacefully in their environment. The objective of this study was to investigate whether individual characteristics, risk perception, self-efficacy and perceived social support were correlated with the willingness to relocate due to floods and landslides. The data were collected from 947 people residing in Gümüşhane Province (Türkiye) using a survey. In the study, a total of ten models were tested with the help of ordinal logistic regression analysis. Consequently, the participants' willingness to relocate due to landslides was determined to be higher than the willingness to relocate due to floods. University students and people with chronic diseases and flood and landslide experiences had a greater willingness to relocate. Residence duration and informal social support were negatively correlated with relocation willingness. Those who believed that they could protect themselves in the event of a flood and landslide were more likely to relocate. Among risk perceptions, probability increased relocation willingness mostly due to floods, while fear increased relocation willingness mostly due to landslides. This study attempted to provide policy makers and scientists insight into disaster risk reduction and disaster risk communication related to relocation.

Fatarib, Husnul; Meirison; Saharuddin, Desmadi; Bahar, Muchlis; Karimullah, Suud Sarim
This article aims to describe the impact of legal dualism within the Ottoman Empire. After Constantinople was taken over, Sultan Muhammad Al-Fatih instituted a significant policy, including issuing laws and regulations for the benefit of society; then, there was also a dualism system within the Ottoman Empire, which was visible during the reign of Sultan Sulaiman I. During this time, foreign nationals were mainly recruited, and foreign traders began to gain impunity at the peak of power. This then prompted several questions, such as were the sultans free to create the laws they wanted, or was Islamic law still binding on them? Was Sultan's law an innovation from the Ottoman Empire or a legacy from the preceding dynasty in the form of Capitulation? To address those issues, the authors conducted a comparative historical analysis of various types of literature. We used a descriptive qualitative approach to Qānūn's position, which served as a springboard for foreign intervention in an Empire that was strong but weak in political policies which occasionally strayed outside the corridor of Islamic Sharia which had become customary and national culture. The tolerance separated from the corridors of Islam derailed during the crisis. This became a springboard for legal dualism in a state body with integrity in various dimensions.

Cicen, Yildirim Beyazit
It is important to note that institutional quality has a substantial impact on a country's long-term economic growth, which influences other economic indicators, such as inflation and monetary policy. An indepth examination of the existence of this crucial relationship was conducted by applying a novel and robust panel Yilanci-Gorus Fourier causality test between 2000 and 2019 to 24 developing countries, in order to detect this relationship. A recent inflation rate, the standard deviation of inflation, and sound money are all interconnected and mutually causally related to property rights and the quality of the legal system. Weakness in institutions can exacerbate financial shocks, thereby affecting monetary indicators, and monetary policies will deteriorate the quality of the institution as a result.

Kaya, Selim
In the current study, the effects of silver (Ag) additive on the radiation shielding efficiency of BiPbSrCaCuO superconducting ceramics was calculated using the EGS4 code and discussed theoretically by comparison with XCOM data. The mass attenuation coefficients (µ/ρ) for BiPbSrCaCuO superconductor ceramics and their contents were investigated theoretically (WinXcom and EGS4) at gamma-ray energies ranging from 59.5 to 1332 keV. The theoretical values were computed in the energy range from 1 keV to 100 MeV using the WinXcom program. Then, using the mass attenuation coefficients, some shielding parameters were determined, such as the mean free path (MFP), the half value layer (HVL), the effective atomic number (Zeff), the radiation protection efficiency (RPE), the macroscopic fast neutron removal cross-sections (ΣR, cm−1) and the gamma-ray kerma coefficients ((Formula presented.)). Theoretically, the results obtained with XCOM and EGS-4 were found to be in good agreement. The radiation shielding efficiency (RPE), neutron removal cross-section (ΣR, cm−1), maximum and semi-valent layer (HVL), and mean free path (MFP) values were found to be smaller for BiPbSrCaCuO superconducting ceramics as the silver (Ag) contribution was increased. Data from this study can guide further research and development of shielding materials for gamma-ray and neutron shielding.

Gültekin, Zarife; Dağ, Serhat
gIn this study the changes in various geomechanical properties were studied for sandstones cropped out at the Mescitli region of the Gümüşhane city under different saturation and anisotropy conditions. For this purpose, 225 specimens were prepared considering the lamination planes of those were chosen to have orientation of 0, 30, 45, 60 and 90° relative to loading direction. Index properties of the sandstones such as dry unit weight (dryg), saturated unit weight (sat), water absorption by weight (Aw) and water absorption by volume (Av) were assigned. In accordance with the objective of study P wave velocity, uniaxial compressive strength and indirect tensile strength values were determined based on different saturation and anisotropy conditions. It was noted as a result of the observations carried out that specimens parallel to lamination have higher wave velocities in general when compared with specimens that are perpendicular to lamination planes. While uniaxial compressive strength values for sandstones are high for specimens which are parallel and perpendicular to lamination, the lowest strength value was observed in specimens with an anisotropy angle of 30°. In addition, it was also observed that the strength values decrease at a significant level with increasing saturation conditions. Strength anisotropy ratio (RUCS) for sandstones varies between 1.28–1.49 based on different saturation conditions. Similarly, while indirect tensile strength values were higher in specimens that were parallel and perpendicular to lamination, they were lower for other anisotropy orientations. Indirect tensile strength values also decreased with increasing degree of saturation.

Goktas, Sonay; Aktug, Cemile; Gezginci, Elif
Background: During the COVID-19 pandemic, intensive care nurses may experience ethical issues related to fear of transmission, limited resources, and increased workload. Nurses' moral sensitivity and courage may have a role in dealing with these problems. Aim: The purpose of this study was to assess intensive care nurses' moral sensitivity and moral courage during the COVID-19 pandemic. Design: Descriptive cross-sectional survey. Methods: A total of 362 nurses working in the intensive care units of pandemic hospitals in Turkey participated in the study between January and March 2021. Data were obtained using a personal information form, the Moral Sensitivity Questionnaire, and the Nurses' Moral Courage Scale. A link to the online data collection tools was sent to the management of participating institutions, who forwarded it to nurses. Reporting followed the CHERRIES guidelines. Results: In this study, the response rate of nurses was 89%. The nurses' total mean moral sensitivity score was 90.70 ± 28.89 and their mean moral courage score was 82.08 ± 13.51. A weak inverse correlation was found between the nurses' moral sensitivity and moral courage scores (r = −.176, p =.001). Total moral sensitivity score differed significantly according to years of Intensive care unit (ICU) experience (p =.007). Total moral courage scores increased significantly with education level (p =.012), years of nursing experience (p =.016), and willingness to work in the ICU (p <.001). Conclusion: The study suggests that nurses working in the intensive care unit during the pandemic had moderate moral sensitivity and high levels of moral courage. Nurses' sociodemographic characteristics and ICU work conditions may affect their moral sensitivity and moral courage. Relevance to Clinical Practice: The results of this study can help guide efforts to improve moral courage and sensitivity and address ethical issues among ICU nurses.
AtıfScopus42WoS37OpenAlex46İncele - MakaleAçık Erişim2023Scopus SJRQ1A comparative study of evolutionary computation and swarm-based methods applied to color quantization
Pérez-Delgado, María-Luisa; Günen, Mehmet Akif
Color Quantization (CQ) is a complex and hard problem because selecting the best set of colors from many available colors and using that set to obtain a good quality image is an NP-complete problem. The use of evolutionary computation and swarm-based methods to solve search and optimization problems has increased dramatically in recent years. This article compares some of these methods in order to solve the CQ problem. The following methods were used to generate CQ images: Particle swarm optimization, Artificial bee colony, Adaptive differential evolution, Success-history based adaptive differential evolution (with and without linear population size reduction), Cuckoo search, Firefly algorithm and Shuffled-frog leaping algorithm. For the first two methods, two variants were considered. Thus, a total of ten metaheuristics were compared with four classical CQ methods (Variance-based, Median-cut, Binary splitting and Wu's methods) applying them to a set of benchmark images and considering four different palette sizes (32, 64, 128, and 256 colors). Three error measures were considered to compare the methods: the mean squared error, the mean absolute error and the peak signal-to-noise ratio. Some of the swarm-based methods analyzed include a recently proposed CQ method using ants. Although they have a slow computational speed in the experimental studies, the ant-based methods are significantly better than all other methods according to the Wilcoxon signed rank test. In general, despite their speed, classical methods underperform the other ten methods both qualitatively and quantitatively.

This study compared the removal efficiencies of Basic red 46 from aqueous solutions with and without ultrasound-assisted processes using lignite as a low-cost adsorbent. The effects of various experimental parameters such as contact time, adsorbent dosage, initial solution, pH, initial dye concentration and temperature on the dye removal efficiency were investigated. The experimental results were modelled by the kinetic and isotherm models. Both of processes fitted well to pseudo-second-order kinetics and the Langmuir model with highest correlation coefficients for all of three temperatures. The results showed that the influence parameters have a different effect on the removal efficiency in the presence and absence of ultrasonic irradiation. When the results obtained for both processes are compared, it is seen that the removal efficiency obtained with the ultrasound assisted process is much higher than that obtained with non-ultrasound assisted process at high dye concentrations. The removal efficiency of ultrasound-assisted and unassisted processes was found to be 81.5% and 54.6%, respectively, at 80 mg/L dye concentration and 60 min. Thermodynamic parameters showed that the adsorption process was spontaneous and exothermic. The enthalpy and entropy changes for the ultrasound-assisted process were –9.35 kJ/mol and –0.03 kJ/K·mol, respectively.

Merdan, Mehmet; Merdan, Merve; Şahin, Ridvan
In this study, Lane-Emden complex differential equations have been randomized by selecting random variables for the coefficients, initial conditions, and force functions of complex differential equations. In addition, by finding the solutions of the obtained random complex differential equations, the probability characteristics of the solutions are examined. The random version of the differential transformation method (DTM) is used to obtain an analytical solution close to the solution of the random differential equation. Approximate expected values and variances are calculated using the approximate solution method. The solutions of some random complex differential equations obtained by using random probability characteristics with gamma, normal, and beta distributions were obtained by the DTM method. The probability characteristics obtained are shown graphically with the help of the MAPLE program.

Öztürk, Serkan
A comprehensive evaluation of region-time-magnitude behaviours of aftershocks following the 24 January 2020 (Mw = 6.8) Elazığ-Sivrice (Türkiye) earthquake was achieved by using the characteristic parameters such as b-value, p-value, Dc-value and Mamax value of aftershock occurrences. The b-value was calculated as 0.82 ± 0.02 by considering the magnitude of the completeness value as Mcomp = 1.9, and it is relatively small compared to typical b ≈ 1 for the magnitude-frequency relationship of aftershocks. This low b-value may also be caused by the abundance of aftershocks with ML ≥ 4.0. The p-value was computed as 0.80 ± 0.02 with c-value = 0.279 ± 0.098 and is smaller than the global value of p ≈ 1. This low p-value may be due to a relatively slow decay rate of aftershock activity, and the modified Omori model seems appropriate for the estimation of decay parameters. The Dc-value was estimated as 1.87 ± 0.07. This large value shows that aftershocks are homogeneously distributed and more clustered at larger scales/in smaller areas. The temporal variation of b-value indicates that decreases in b-value may result from the gradual increase in the effective stress following the larger aftershocks. The lowest b-values and Mamax values greater than 5.0 were observed in the north, south and southwest parts of the mainshock including Pütürge and Erkenek segments. These results show that there is an apparent relation between the smallest b-values and the largest Mamax values. The largest p-values were estimated in and around the main shock including Pütürge segment. The regions with the smallest b-value and the largest p-value have high stress and coseismic deformation, respectively. Stress variations and coseismic deformation are extremely effective on the changes of b-and p-values. As a remarkable result, aftershock hazard following the mainshock may be considered extremely related to aftershock parameters, and detailed analyses of the region-time-magnitude characteristics of aftershocks are recommended for a preliminary evaluation following the mainshock.

Kaya, Şevval; Sarıbıyık, Oğuz Yunus
Coating of the metal surface for different fields such as corrosion resistance, hydrophobic surface, and conductivity properties enhance the material quality for different application. Furthermore, controlling the morphological structures and the size of the coating materials is one of the most important factors for designing their functionality. The new approaches to the effect of surface properties at the atomic level on bacterial adhesion offer new perspectives on this subject. In this study, the effect of the different current densities on the morphological microstructural features, microhardness properties, and bacterial attachment behavior of the protective aluminum oxide layer was investigated by using different analytical and instrumental methods. The Staphylococcus aureus was used as a model bacteria for attachment tests. The result presented in the current study exhibited that the crystal morphology, microhardness, and bacterial adhesion features have changed depending on the applied current density. Increasing the current density from 1.5 to 1.7 raises the microhardness from 88 to 126 (Vickers) and causes higher surface roughness by 56 nm, 114 nm and 124 nm respectively. The high number of the attached bacteria were determined on the more roughness surface during the study.

Bulut, Sinan; Günlü, Alkan; Çakır, Günay
Remote sensing technologies have been extensively used in forest management in predicting stand parameters. The goal of this study is to use Landsat 8 and Sentinel-2 satellite images to estimate stand volume, basal area, number of trees, mean diameter, and top height. 180 temporary sample plots were taken in pure Crimean pine stands with varied structure. Reflectance, vegetation indices, and eight texture values were generated from Landsat 8 and Sentinel-2 satellite images. The stand parameters were modelled with the remotely sensed data using multiple linear regression, support vector machine, and deep learning techniques. The results showed that the support vector machine technique provided the highest level of model performance with 45° orientation for number of trees (R2 = 0.98, RMSE%=5.97) and 90° orientation for basal area (R2=0.91, RMSE%=15.22). The results indicated that the texture values presented better results than the reflectance and the vegetation indices in estimating the stand parameters.

Rheumatic diseases (RDs) include a variety of autoimmune disorders defined by severe inflammation, primarily affecting the joints, tendons, ligaments, bones, and muscles. Recent research has revealed the association between rheumatic diseases and gut microbiota, thereby providing insights into the underlying mechanisms of disease pathogenesis. The objective of this study was to evaluate the quantity and quality of scientific research regarding the association between RDs and gut microbiota, as well as to elucidate the characteristics of worldwide research output in this field. The present bibliometric analysis was carried out using the Scopus database, using the keywords "rheumatology," "arthritis," and "gut microbiota." The study involved determining the number of articles, the number of active countries with journals, the identification of prolific authors, and the collection of citation data. Additionally, analyses of trends were conducted. 503 articles in all were reviewed. Collaboration networks were visualized using mapping techniques. The number of articles on RDs and gut microbiota exhibited a consistent pattern from 2002 to 2022 (p < 0.05). The five most productive countries were China (n = 128; 25.45%), the United States (n = 101; 20.07%), Italy (n = 40; 7.95%), the United Kingdom (n = 20; 3.98%), and Japan (n = 17; 3.38%). Israel, Italy, Belgium, and Portugal had the highest values regarding the number of articles per million population. Australia, Canada, and the United Kingdom were the top three countries regarding average citation count. This bibliometric analysis evaluates and synthesizes global scientific output on RDs and gut microbiota. The literature on the association between rheumatic diseases and gut microbiota is growing. Supporting researchers in countries with limited involvement in this field will contribute to its growth.

Hayaloğlu, Pınar; Tümay, Muhammed
Foreign aid is essential in meeting the capital needs of countries that need more resources. However, in the literature, besides the view that foreign aid encourages economic performance, opinions suggest that it has adverse effects on recipient countries. Some ideas argue that the positive impact of foreign aid in recipient countries depends on the institutional quality level of the nations. We examine the relationships between foreign aid, the quality of governance, and economic growth using the dynamic panel data analysis method. The empirical analysis includes samples of 78 low-income countries that used foreign aid from 2000-2019. According to the findings, foreign aid affects economic growth negatively in sample countries. In addition, we find a positive relationship between the quality of governance and economic growth. In line with these findings, we can state that improvements in governance quality will positively impact economic development in the sample nations.
AtıfScopus2WoS2OpenAlex2İncele - MakaleAçık Erişim2023Scopus SJRQ1New paleomagnetic results from Neogene to Quaternary volcanic rocks of north of the Lake Van, Eastern Turkey
Kayın, Sercan; İşseven, Turgay
The Eastern Anatolia is an active tectonic region where the collision between the Arabian and Eurasian plates take place. Due to the subduction of Arabian plate’s oceanic lithosphere under Eurasian plate, widespread volcanism observed in large areas began in Serravallian. There is no consensus in the literature for the tectonic evolution of the region. Therefore, there are many geological and geophysical studies conducted with the intention of explaining the tectonic evolution of Eastern Anatolia by geodynamic models. Our paleomagnetism study aims to reveal the tectonic rotations in order to better understand the development of the prevailing tectonism in the region from the volcanic rocks. Paleomagnetic samples were collected from 86 sites of the Late Miocene–Pleistocene volcanic rocks located at the north of Lake Van. Isothermal remanent magnetization studies show that magnetite is the mineral responsible for magnetization in most rocks, while both magnetite and hematite are responsible for the rest of the rocks. Curie temperatures and alteration degrees of rock samples were also determined by high-temperature susceptibility (HTS) studies. In some samples, titanomagnetite component was observed in the heating phase of the HTS measurements. The absence of this component in the cooling step indicates that Ti-magnetite is transformed into magnetite by alteration. The Pleistocene volcanics show counterclockwise rotation of R ± ΔR = 13.4° ± 3.8°. The Pliocene volcanic rocks were defined in four different groups: south of Erciş Fault, north of Erciş Fault, around Muradiye and north of Van. Also, the remarkable clockwise rotation is observed in the north of Van and near Muradiye R ± ΔR = 24.4° ± 17.0° and R ± ΔR = 6.9° ± 9.4°, respectively. In addition, counterclockwise rotation (R ± ΔR = 14.5° ± 6.1°) is obtained in the southern part of the Erciş Fault, while there is no significant rotation (R ± ΔR = 0.6° ± 7.4°) on the northern side. Late Miocene volcanic rocks show no significant rotation either (R ± ΔR = 1.8° ± 13.7°). Our new paleomagnetic results indicate that the left-lateral strike-slip Çakırbey Fault, located to the east of the Erciş fault and extending roughly in the northeast–southwest direction, may be active.

The radionuclide concentrations of eU (ppm), eTh (ppm), K (%) and dose rate values were measured in Sarıçiçek (Gümüşhane) and Sarıhan (Bayburt) granodiorites for a duration of 5 minutes at each of 532 measurement points. The radioelement ratios (eU/eTh, eU/K, and eTh/K) indicating the origins of the rocks, the geochemical indicators (Ume, F parameter, and eU-(eTh/3,5) rate) showing the uranium mobility and the radioelement concentrations were calculated and mapped within the study areas. The average K, eU, and eTh concentrations were calculated as 2.98%, 3.15 ppm, and 12.45 ppm for Sarıçiçek granodiorite, and 1.83%, 2.73 ppm, and 13.6 ppm for Sarıhan granodiorite, respectively. Higher radioactivity values were observed in basaltic, sedimentary, and ultramafic rock combinations within the granodiorite masses. In the classification according to radioelement ratios, it was concluded that the rocks in the study areas formed as a mixture of upper mantle and crustal materials. In both study areas, there was uranium transport from the granodioritic masses into the surrounding rocks, and accordingly, the rocks in the surrounding formations were enriched in uranium. As a result, radioactivity levels, rock formation origins, and uranium transport of both granodioritic masses and rocks in the surrounding formations were determined by evaluation with radioelement concentration values and ratios and migration parameters. The study areas were characterized by associating them with geology in light of radioactive data.

Introduction. Cystic fibrosis transmembrane regulator (CFTR) modulator therapies improve respiratory function and glycaemic control in patients with cystic fibrosis (CF). The direct effect of CFTR modulator therapies on pancreatic function in patients without preexisting diabetes remains unclear. Case Presentation. An 18-year-old female with CF caused by F508del/F508del mutation, who had no diabetes, developed postprandial hypoglycaemias 6 months after initiation of elexacaftor, tezacaftor, and ivacaftor combination therapy (ETI). Symptoms were persisted after brief discontinuation of ETI, but her symptoms and time-in-hypoglycaemia had improved remarkably by avoiding high glycaemic index-foods. Discussion. This case of hypoglycaemia associated with CFTR modulator therapy in a patient without preexisting diabetes suggests that CFTR modulator therapy has the potential to directly affect glucose homeostasis. There might be an improvement in insulin secretion as well as a reduction in systemic insulin resistance. Conclusion. Treatment of CF patients without diabetes with CFTR modulator therapies can cause recurrent hypoglycaemic episodes which resolve with dietary measures.

Kaya, Nahsan; Atalay, Ezgi; Demir Doğan, Melike
Avalanches kill more than 150 people every year, although no one knows the exact figure. Additionally, the mortality rate in avalanche incidents may reach up to 70% due to factors such as the lack of knowledge, experience, and organization of search and rescue personnel. This cross-sectional study was conducted to determine the awareness on avalanche and the level of knowledge on search and rescue among personnel who respond to avalanche incidents and participate in search and rescue activities. The sample consisted of 304 individuals who agreed to participate in the study between June and July 2021. Data were collected using an information form on socio-demographic characteristics and a survey prepared by the researchers upon the relevant literature review. It was found that while 65.8% of the participants were female, 34.2% were male. Their mean age was 29.69±8.50 years. The rate of those participating in search and rescue activities in case of a disaster was 44.1 %. The participants had a moderate level of knowledge on avalanche search and rescue as well as on-site medical management of avalanche victims. Those who participated in search and rescue activities in case of a disaster had a higher level of knowledge on avalanche search and rescue than those who did not. Those who were trained on avalanche search and rescue (preparedness, response) had higher levels of knowledge on avalanche search and rescue and on-site medical management of avalanche victims when compared to those who were not. As a consequence, it was determined that participation in search and rescue activities in a disaster increased the personnel’s level knowledge. Also, the related training elevated the levels of knowledge on both avalanche search and rescue and on-site medical management of avalanche victims.

Yilmaz Camoglu, Aslihan; Ozdes, Duygu; Duran, Celal
The study focused on fabricating a novel magnetic Fe3O4 loaded and EDTA modified brewed tea waste (TW-Fe3O4-EDTA) as a cheap, environmentally friendly, and efficient adsorbent for the removal of Cr(VI) ions from aqueous medium in a batch system. Characterization of the prepared adsorbent was performed with different techniques. Adsorption experiments were implemented at different conditions including initial solution pH (1.0–7.0), equilibrium time (1–480 min), adsorbent dosage (1.0–20.0 g L–1), and initial Cr(VI) concentration (50–1000 mg L–1). The optimum adsorption performance was observed at pH 2.0 with 120 min of contact time. Maximum adsorption capacity of 114.9 mg g–1 was acquired for TW-Fe3O4-EDTA which is much higher than the recently developed adsorbents for Cr(VI) removal. Adsorption process was well explicated by Freundlich isotherm model and the adsorption rate is described in accordance with pseudo-second order kinetic model. It was observed that common salts did not have a notable influence on Cr(VI) adsorption. The results of the study indicated that TW-Fe3O4-EDTA can be applied as an effective adsorbent in heavy metal removal as an alternative to many expensive adsorbents available in the literature.
