    Çakmak, Seher; Uzun, Sevda; Demi̇r Çam, Sevgi; Tamam, Yusuf

    Background: The aim of this study is to evaluate the psychosocial dimension of Parkinson’s disease and the life experiences of patients with a phenomenological approach. Methods: In this phenomenological study, semi-structured in-depth interviews were conducted with 20 Parkinson’s patients who applied to the neurology outpatient clinic of a state hospital in a province in southern Turkey. Criterion sampling method, one of the purposive sampling methods, was used to reach the sample group. Interviews continued until data saturation was achieved. All interviews were recorded on a voice recorder after obtaining the necessary permissions from the patients and then transcribed. The data of the study were evaluated using thematic analysis. The study was conducted and reported according to the COREQ checklist. Results: Data analysis revealed three main themes (metaphors for Parkinson's disease, effects of Parkinson's disease, symptom management and psychosocial needs in Parkinson's disease) and eight sub-themes (metaphors for physical effects, metaphors for mental effects, metaphors for social effects, mental, physical, social, symptom management and psychosocial needs). Conclusions: As a result of this study, it was determined that Parkinson's disease negatively affects patients psychosocially and they have difficulty in coping. It is recommended to implement research and application centers for Parkinson's patients with a focus on psychosocial support and to carry out awareness and awareness-raising studies on Parkinson's disease. Studies on this subject are very limited and it is recommended that large-scale studies on psychosocial problems in individuals with Parkinson's disease be conducted in the future.

    Hydrometallurgical Extraction of Aluminum and Rare-Earth Elements (REEs) from REE-Bearing Bauxite Ores: Recent Advances

    Uysal, Turan; Supriyatna, Yayat Iman

    Rare-earth elements (REEs) are geologically widespread, but their mining and especially processing are concentrated in a small number of countries; as demand grows, some specific REEs may face supply shortages in the near future. Consequently, owing to their economic potential even at low concentrations, ability to provide alternative supply opportunities, and process development potential, various countries are conducting studies on REE production from secondary geological sources such as high-silica bauxite ore. This study provides a detailed examination of aluminum (Al) and REE recovery from bauxite ore, emphasizing sustainable utilization of these resources. In this context, the study presents the technological evaluation potential of these deposits in the context of modern demands, the acquisition process, and an analysis of the main technical difficulties in this process. Furthermore, the application of both mechanical and thermal activation methods in conjunction may prove more economically viable and environmentally sustainable by reducing the temperature requirements of fossil fuel-consuming heat treatment. The development of sustainable Al and REE recovery technology from bauxite ore is of significant importance, not only in terms of mitigating supply risk but also as an alternative source for REE production.

    Selective Determination of Trace Co(II) and Cu(II) in Food and Environmental Matrices via Carrier Element-Free Coprecipitation Using a Novel Thiosemicarbazone-Derived Schiff Base

    Bulut, Volkan N.; Demirci, Hamit; Ozdes, Duygu; Gundogdu, Ali; Bektas, Hakan; Soylak, Mustafa; Duran, Celal

    A carrier element-free coprecipitation (CEFC) method was developed for the preconcentration and determination of trace Co(II) and Cu(II) in environmental and food samples using a novel thiosemicarbazone-derived Schiff base ligand (MBITAH). Unlike conventional coprecipitation approaches, the proposed strategy eliminates the need for inorganic carriers, reducing potential interferences and improving selectivity toward the target analytes. Under optimized conditions (pH 7.0, 1.5 mg ligand), quantitative recoveries were achieved with limits of detection of 1.16 and 0.79 µg L⁻1 for Co(II) and Cu(II), respectively. A preconcentration factor of 50 enabled sensitive determination by flame atomic absorption spectrometry (FAAS) with good precision (RSD ≤ 3.7%). The method exhibited good tolerance toward common matrix ions and was validated using certified-reference material (CRM-SA-C Sandy Soil C) and spike/recovery tests, showing agreement with certified values (p > 0.05). Its applicability was demonstrated in sea water, stream water, and food samples (red lentil and bulgur), confirming reliable performance in complex matrices. Compared with previously reported approaches, the proposed CEFC method offers a favorable balance between analytical performance, simplicity, and cost-effectiveness. In addition, greenness assessment using the AGREE tool yielded a score of 0.45, indicating a moderate-to-good level of environmental friendliness.

    Monthly precipitation trends in Türkiye under complex topography and varying climate: a seasonal Mann–Kendall and innovative polygon trend framework

    Şan, Murat; Nacar, Sinan; Kankal, Murat

    The impacts of climate change are increasingly sensible, and Türkiye with its varied topography and diverse climate types is particularly exposed to these shifts. Understanding how precipitation patterns are evolving across its regions is therefore critical. While trend analysis is a widely used tool for this purpose, conventional approaches overlook periodicity, limiting their practical value for water resource management and irrigated agriculture. Therefore, this study aims to examine seasonal trends in long-term (1969–2020) monthly total precipitation in Türkiye, in which each calendar month is treated as a separate season in the sense of seasonal trend-analysis terminology, accounting for altitude, slope, geographical region, and Köppen climate classification. For this purpose, the seasonal Mann-Kendall (SMK) test and the innovative polygon trend Wilcoxon significance test (IPWST), a relatively new graphical method, were used, and the two approaches were comparatively evaluated. According to the study’s results, the rate of increase in coastal areas, specifically the Aegean and Black Seas, exceeds the rate of decrease. In contrast, the reverse is observed in inland and eastern regions. The IPTWST method indicates a more pronounced increasing trend in the Marmara and Mediterranean regions. Furthermore, although analogous trends are observed at lower slopes and altitudes, analyses indicate that these trends are more strongly related to altitude, with the rate of increase decreasing as altitude increases. The IPTWST identified significant or weak trend signals at a larger number of stations than the SMK, particularly in relation to altitude. Nationwide, the two methods revealed significant increases of 7% and decreases of 6%, respectively; this pattern was supported by statistical tests, reflecting the variability of regional climates and the influence of topographic factors on trend analysis.

    A novel decision-making approach based on regret theory under bipolar Z-number information

    Altun, Fatma; Köseoğlu, Ali; Şahin, Rıdvan

    This study introduces a new set theory called bipolar fuzzy Z-number set that makes it possible to express an information both bipolar from positive and negative perspectives, and with the reliability of it. Then, besides basic set-theoretical operations and the score function, a new distance measure is also presented. Furthermore, a decision method integrating with regret theory is proposed. Additionally, to compute the weights of criteria under bipolar Z-number information, a method in which objective and subjective criterion weights are considered simultaneously is introduced by combining the weights found by SWARA and MEREC. Also, a model with standard deviation is developed to obtain decision maker’s weights. Finally, the problem of selection of paper raw material is handled to demonstrate stability and advantage of the proposed method.

    Yüksel, Duygu; Başeğmez, Mehmet; Kan, Fahriye

    This study aimed to determine the protective role of boric acid (BA) in high fructose (HF)-induced liver and kidney toxicity in a young rat model. High-fructose consumption causes serious damage to liver and kidney tissue in healthy individuals and contributes to the emergence of various metabolic diseases. Thirty-two healthy female Wistar albino rats (250–300 g weight and 3–4 months) were randomly distributed into four equal groups (n = 8): control, high fructose % 20 (HF), boric acid 20 mg/kg (BA), and HF + BA. High fructose was freshly prepared and administered to the rats as 20 g of d-fructose dissolved in 100 mL of tap water daily for a duration of 30 days. Boric acid (20 mg/kg) was administered through gastric gavage throughout the 30-day study period. At the end of study, blood, liver, and kidney were collected from rats. The results indicated that high fructose induced increased glucose, total cholesterol, triglyceride, and urea levels in rat serum. Boric acid administration significantly decreased glucose, total cholesterol, triglyceride, and urea levels in HF + BA groups. The results indicated that high fructose-induced oxidative stress by increasing the level of MDA and by decreasing GSH levels, and CAT activity in the liver and kidney of rats. However, oral BA administration significantly decreased MDA levels and increased GSH levels, and CAT activity (p < 0.05). Furthermore, BA significantly reduced high fructose-induced histopathological and Immunohistochemistry alteration in the liver and kidney tissues. In conclusion, BA may prevent the oxidative imbalance and histopathological and immunohistochemical damage caused by high fructose in liver and kidney tissues in rats.

    Petrochemistry and geochronology of Middle Eocene high-K calc-alkaline I-type Kazıkbeli pluton, NE Turkey: implications from zircon U-Pb ages and Sr-Nd-Pb-Lu-Hf isotope data

    Güloğlu, Zikrullah Samet; Kaygusuz, Abdullah

    The Kazıkbeli pluton, located in the Kürtün (Gümüşhane) region of the Eastern Pontides, NE Turkey, was studied by employing zircon U-Pb geochronology, whole-rock geochemistry, Sr-Nd-Pb and zircon Lu-Hf isotope geochemistry. LA-ICP-MS U-Pb zircon dating revealed that the gabbroic diorite and granodiorite components of the pluton solidified during the Lutetian epoch of the Middle Eocene, at approximately 46.10 ± 0.26 Ma and 45.37 ± 0.29 Ma, respectively. The pluton is composed of calc-alkaline rocks, ranging from gabbroic diorite to granite (SiO2 = 55.3 to 72.4 wt%). These I-type rocks are typically metaluminous but exhibit peraluminous tendencies in some cases. They are enriched in large ion lithophile elements and display concave chondrite-normalized rare earth element patterns (LaN/YbN = 4.39 to 6.67) with negative Eu anomalies (EuN/Eu* = 0.45 to 0.80). The initial εNd values ranged from 1.85 to 2.24, and the initial 87Sr/86Sr(i) ratios ranged from 0.70458 to 0.70484, consistent with a mantle source in the isotope ratio diagram. The initial 206Pb/204Pb(i), 207Pb/204Pb(i), and 208Pb/204Pb(i) ratios ranged from 18.505 to 18.571, 15.595 to 15.601, and 38.560 to 38.590, respectively. They have positive εHf(i) values (5.75 to 8.03), located between depleted mantle and chondrite evolution values. Fractional crystallization of plagioclase, hornblende, and Fe-Ti oxide minerals played a significant role in the magma evolution, while assimilation and magma mixing may have had a minor influence. Collectively, the evidence suggests that the primary magma source for these plutonic rocks was an enriched lithospheric mantle. Subsequent differentiation within crustal magma chambers, with limited crustal contamination, shaped the final magmatic evolution.

    Ensuring Circularity through Outsourcing Decisions in Solar Photovoltaic Supply Chains

    Erol, Ismail; Peker, Iskender; Benli, Tolga; Ar, Ilker Murat

    Because solar photovoltaic (SPv) panels have seen such significant cost reductions in recent years, it has proven to be by far the most dynamic forms of renewable power generation. However, the transition from linear to circular is also crucial for building sustainability in SPv supply chains. The circular economy (CE) is appealing in part because of its ability to bring economic and environmental development objectives together to ensure sustainable production and consumption. To aid in the shift to a more circular economy, several circular-based strategies for various functions such as procurement can be developed. In this study, critical success factors (CSFs) to ensure circular outsourcing structure in SPv supply chains are identified and scrutinized. To achieve this, a multi-criteria-based methodology is proposed. The findings of this study argue that understanding the actual implications of not converting to circular outsourcing (C12) is the most significant cause CSF. This study also provides several implications.

    Comparison of different animal milks on microbiological, physicochemical, sensory properties, and volatile component profile of Kefir

    Meral-Aktaş, Hacer; Ürkek, Bayram; Aktaş, Haktan; Baltacı, Cemalettin; Çetin, Bülent; Şengül, Mustafa

    In this study, the effects of cow, buffalo, ewe, and goat milk on the microbiological, physicochemical, sensory properties, and volatile component profile of kefir were examined during storage. Key microbial counts, including lactic cocci, lactic bacilli, and yeast, varied among kefirs, with lactic bacilli and lactic cocci decreasing over time, while yeast counts increased. The titratable acidity ranged from 1.12 to 1.16%, and pH values varied between 4.51 and 4.83. Sensory analysis showed that cow milk kefir received the highest consumer appreciation, while goat milk kefir was least favored. Notably, ewe milk kefir contained the highest benzoic acid content. Principal component analysis identified distinct clusters in the volatile profiles of the kefirs. Our results suggest that buffalo and ewe milk kefirs may be viable alternatives to cow milk kefir, with potential for consumer acceptance based on sensory properties.

    A comprehensive analysis of the effect of BaO incorporation on Gamma-Ray attenuation characteristics in SiO₂-B₂O₃-SrO-ZrO₂ glass systems

    Kaya, Selim

    This work presents an analysis of the effect of BaO incorporation on the gamma-ray attenuation properties of systematically evaluated SiO₂-B₂O₃-SrO-ZrO₂ glass matrices. Radiation shielding parameters determined using XCOM and EGS4 calculation codes were compared. There was an increase in glass density from 5.84 g/cm3 to 6.32 g/cm3 when the BaO content rose from roughly 10% to 40%. Using sophisticated WinXCom and EGS-4 calculations, the mass attenuation values (µ/ρ) of BaO doped SiO₂-B₂O₃-SrO-ZrO₂ glass systems (abbreviated BaSiBSZ) were found. This study systematically and thoroughly evaluated the effect of BaO integration on the radiation shielding capabilities of the glass system over a wide range of gamma-ray photon energies, specifically between 59.5 keV and 1332 keV. Initially, HVL (half-value layer) and MFP (mean free path) values were derived from the calculated mass attenuation coefficients. The evaluation of several crucial shielding parameters, including RPE, Zeff, ΣR, and kγ, came next. The steady reduction of SrO oxide concentration and substitution of BaO in BaSiSBZ glass systems resulted in notable modifications in radiation protection properties. The BaSiBSZ glass systems showed a similar decrease in both HVL and MFP at a constant energy level as the BaO doping concentration was progressively raised. Concurrently, a notable enhancement was noted in RPE, Zeff, ΣR, and kγ coefficients. The results demonstrate that higher BaO concentrations greatly enhance the material's radiation-shielding capabilities, enhancing both photon and neutron attenuation and bolstering the overall performance of the glass system.

    A comparative study of Kolmogorov-Arnold networks and multilayer perceptrons for software defect prediction with SHAP analysis

    Turk, Salih; Coskuncay, Ahmet

    Software defect prediction is essential for enhancing software quality by detecting software errors early in the development lifecycle. This article presents the usage and a detailed evaluation of Kolmogorov-Arnold Networks (KAN) and Multilayer Perceptrons (MLP) over eleven prevalent software defect prediction datasets, namely CM1, JM1, KC1, KC3, MC1, MC2, MW1, PC1, PC3, PC4, and PC5. The defect prediction models were established and evaluated using five principal performance metrics: Accuracy, Precision, Recall, F1 Score, and Area Under the Curve (AUC). The experimental findings indicate that KAN consistently surpasses MLP in all datasets and metrics. KAN attains an average accuracy enhancement of almost 12% compared to MLP and demonstrates substantial improvements in precision and recall, rendering it more dependable in detecting defected modules. The paired t-test findings indicate that the performance disparities between KAN and MLP are statistically significant (p-value< 0.05) for the majority of metrics. Also SHAP analysis was performed to determine the important rankings of features for all datasets according to the FastKAN model. This study underscores the promise of KAN as a superior alternative to traditional neural networks for software defect prediction. The results highlight the significance of the usage of sophisticated neural network topologies in tackling intricate software engineering challenges.

    Exploring the Correlation of Physiological Stress Signals with Student Exam Performance: A Preliminary Study

    K. Kasap, Ayşegül; Kurt, Burçin

    Stress responses in real-world settings are less studied compared to controlled laboratory environments, limiting our understanding of their impact on cognitive performance. This study investigates the relationship between physiological stress signals and academic performance using an open-access dataset of 10 students assessed across three exam sessions (Midterm 1, Midterm 2, and Final Exam). Physiological measures, including electrodermal activity (EDA), heart rate (HR), and skin surface temperature (TEMP), along with exam grades, were analyzed using traditional hypothesis testing, bootstrap method, correlation analysis, and regression tree modeling. To address the small sample size, we validated traditional hypothesis test results with the bootstrap method, and both approaches were compatible. Hypothesis testing revealed no significant differences in physiological measures across exam sessions, supporting the null hypothesis. Grades differed significantly between the final exam and both midterms (p < 0.05). Stress fluctuations were also analyzed across three periods (beginning, middle, and end) for each exam, revealing temporal response variations. Correlation analysis showed a moderate negative relationship between EDA and HR (r = − 0.504, p < 0.01) and a weak positive relationship between EDA and TEMP (r = 0.417, p < 0.05), both intensifying during the final exam. Regression analysis explained 78% of the variance in grades (R2 = 0.78), with regression tree modeling identifying lower skin temperature (< 28 °C) and higher EDA (≥ 0.19) as predictors of poorer performance. These findings underscore the interplay between physiological stress responses and academic outcomes, emphasizing the need for further research and interventions to support student success.

    “I Am Learning to Protect Myself with Mika”: An Evaluation of Self-Protection Behaviors of Turkish Preschoolers

    Yılmaz Irmak, Türkan; Kızıltepe, Rukiye; Eslek, Duygu; Kütük, Bahtım; Güney, Onuray

    Child sexual abuse (CSA) prevention programs contribute to increases in children’s knowledge and skills to protect themselves from CSA. However, there is a paucity of research investigating self-protection behaviors among children to demonstrate whether relevant CSA knowledge and skills are transferable in risky situations. We aimed to examine the effectiveness of the “I am learning to protect myself with Mika” program on preschool children’s self-protection behaviors. The sample included 51 preschool children (54.9% girls) from Izmir, Turkey and their parents. The mean age of the children was 65.57 months (SD = 7.21). The present study employed a posttest-only control group design, and the classrooms were randomly assigned to the intervention and wait-list comparison groups. The participating teachers implemented the program over a five-week period. Then, children’s self-protection behavior was assessed with children from both groups using a role-play scenario involving a request from a stranger. Accordingly, we tested whether children in the intervention group were more likely to demonstrate self-protection behaviors compared to those in the comparison group. The findings showed that the intervention group (77.3%) rejected the offer from strangers and behaved more safely than did the wait-list comparison group (24.2%; χ2(1) = 13.879, p < 0.001). “I am learning to protect myself with Mika” was found to be effective in contributing to preschoolers’ self-protective behaviors. The promising results obtained in this study may encourage further exploration of the behavioral outcomes of sexual abuse prevention programs.

    Analysis of drought in upper Moulouya Basin (Morocco): a combination of drought indices, classic and innovative trend tests

    Qadem, Zohair; Hadria, Rachid; Ettaqy, Abderrahim; Kankal, Murat; Şan, Murat; Nacar, Sinan

    This study aimed to examine the temporal and spatial variation of drought in the upper Moulouya Basin, Morocco’s arid and semi-arid region. For this purpose, the Standardized Precipitation Index (SPI) was calculated at various time scales (3, 6, 12, and 24 months) using precipitation data collected from eight stations between 1977 and 2019. The data trends were analysed by classical modified Mann-Kendall (MMK) and Innovative Trend Analysis (ITA). Severe drought events were identified in the 1980s, and 1998–2000, while exceptionally wet years were recorded in periods 1996–1997 and 2008–2012. SPI trend analyses revealed a holistic increase on almost all timescales and at all stations. The increase was found to be higher in more extended time scales. Except for a few stations, SPI values in dry, normal, and wet classes of ITA method increased in the second half (1998–2019) compared to the first half (1978–1997). The ITA method detected different trends for different classes at two stations compared to the MMK method. This situation revealed the importance of analysing the trends of different methods in drought studies. These results are essential for water resources management and adaptation to climate change in arid and semi-arid zones.

    In the present study, einkorn wheat flour (Tiriticum monococcum L.) was incorporated into a special dried bread (peksimet) formulation produced from sourdough breads at different concentrations (0–10–20–30–40 and 50 g 100 g−1) and some physicochemical and nutritional (total dietary fiber, resistant starch, glycemic index, acrylamide content) characteristics and sensory properties of the samples were investigated. The total dietary fiber content of the bread samples ranged from 3.00 to 6.17 g 100 g−1. The highest acrylamide content (247.54 µg/kg) was obtained using an einkorn flour level of 40 g 100 g−1. Einkorn wheat flour resulted in a significant decrease (from 94.61 to 89.23) in the glycemic index level of the bread samples (p < 0.05). Bread enriched with einkorn wheat flour (50.0 g 100 g−1) received the highest overall acceptability score. In conclusion, einkorn wheat flour could be used in a special dried bread formulation to enhance its nutritional quality.
