Kenek, Gökhan; Sımsek, Tugçe
This study aims to examine the impact of workaholism on work-family conflict and whether employees’ gender moderates this relationship. The research was conducted with 401 academicians from all public universities (8 in total) in Ankara, selected through a snowball sampling method. Data were analyzed using MPLUS 7 and SPSS 26 statistical software. The findings revealed that workaholism has a significant positive effect on work-family conflict; however, gender did not moderate the relationship between the two variables. Additionally, the results indicated that attitudes toward both workaholism and work-family conflict differ significantly by gender, with women academics reporting higher levels than their male counterparts. These findings suggest that although female academics report higher levels of both workaholism and work-family conflict, gender does not alter the strength of the association between the two, indicating that workaholism contributes to work-family conflict in a similar way across genders.

Akyol, Mehmet; Soyyigit, Semanur
This study assessed the environmental technological innovation (ETI) of the 13 countries with the highest industrial added value (China, the United States, Japan, Germany, India, the United Kingdom, South Korea, France, Russia, Italy, Mexico, Brazil, Indonesia) over the period between 1992 and 2019. The objective is to evaluate the impact of carbon dioxide (CO2) emissions, trade openness (TO), and economic growth (EG) on the ecological footprint (EFP). In this study, a panel data analysis was conducted utilizing the second-generation PANIC unit root test, the Westerlund cointegration test, the Dumitrescu-Hurlin causality test, and the common correlated effect mean group (CCEMG) and augmented mean group (AMG) estimator methods. The results of the analysis demonstrate that, according to the CCEMG, ETI exerts a mitigating influence on EFP in Indonesia. In numerous countries, CO2 has been observed to increase EFP, whereas in a select few countries, EG has been found to have a similar effect. Conversely, in China and South Korea, TO has been identified as a factor contributing to an increase in EFP, while in the United States, it has been identified as a factor that contributes to a decrease in EFP. The AMG indicates that ETI results in a decrease in EFP in Brazil and Indonesia, while simultaneously producing an increase in Mexico. While CO2 is observed to increase EFP in numerous countries, EG is seen to increase EFP in many countries, although this is only the case in India. TO is found to decrease EFP in China, India, South Korea, and Brazil, while simultaneously increasing it in Germany. The empirical evidence suggests that policies aimed at limiting uncontrolled economic growth, prioritising environmentally friendly technological innovations, improving international trade processes and policies with the objective of reducing emissions, and developing environmentally friendly processes and products in production are likely to be effective.

İncele - MakaleYalnız künye2025Scopus SJRQ1Modeling the Compressive Strength of Fiber-Reinforced Alkali-Activated Concrete Using Non-Destructive Methods in Short Curing Periods
Aksüt, Yavuz Selim; Çullu, Mustafa; Yetgin, Sukru
The indirect assessment of concrete compressive strength using non-destructive techniques, including the Schmidt rebound hammer and ultrasonic pulse velocity methods, is crucial for evaluating and tracking the strength of structural concrete used in construction and rehabilitation projects. However, studies focusing on alkali-activated concrete (AAC) remain insufficient. This study investigates the mechanical properties of fiber-reinforced alkali-activated concretes (FAACs) produced with short curing times, addressing this gap in the literature. Ground blast furnace slag (GBFS) was used as the binder, and waste volcanic rock dust (RD), produced in a natural stone processing plant, served as a fine filler. These materials were activated with sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) to produce alkali-activated concrete, both without fibers (AAC) and with fibers (FAAC). Steel fiber (SF) and polyester fiber (PYF) were used separately and in hybrid forms at 0.25%; 0.50%; 0.75%, and 1.0% volume fractions, resulting in a total of 117 cubic specimens (15x15x15 cm). The specimens' mechanical properties were evaluated using regression analyses based on data from Schmidt rebound number (RN), ultrasonic pulse velocity (UPV) non-destructive methods and uniaxial compressive strength (UCS) destructive tests. Optimized functions predicting compressive strength based on RN and UPV measurements were developed, highlighting the significant effects of fiber type, ratio, and mode of use. Additionally, multivariate prediction models were statistically developed using data from the three test methods.

Eyüboglu, Kayahan; Keskin, Cem
Spontaneous retroperitoneal hemorrhage (SRH) is a rare and potentially life-threatening condition, often challenging to diagnose and manage, especially in elderly patients with multiple comorbidities. Psoas hematoma is a known complication that can be associated with anticoagulation therapy. A 93-year-old male patient with a history of atrial fibrillation, chronic heartfailure, and anticoagulant use (apixaban) presented with complaints of dizziness following a fall in the bathroom. He was initially assessed in the neurology clinic for potential cognitive symptoms; however, while awaiting assessment, he experienced a syncopal episode, resulting in his transfer to the emergency room. The patient had a significant reduction in hemoglobin levels, necessitating additional examination. Imaging revealed an 8 cm left psoas hematoma with active extravasation. The patient received a blood transfusion, vitamin K, and therapeutic interventions, including interventional radiology, which effectively halted the hemorrhage. This case highlights the diagnostic complexity and therapeutic challenges posed by spontaneous retroperitoneal hemorrhage in elderly patients, especially those on anticoagulant therapy. Early recognition and appropriate intervention are crucial for patient recovery.
- MakaleYalnız künye2025Economic vulnerability amidst contagion: analyzing unemployment via Covid-19-induced transaction costs
Cicen, Yildirim Beyazit
This study delves into the pandemic's influence on unemployment rates, employing the concept of transaction costs. Given the virus's infectious nature, each transaction carries the risk of infection. In this study, Covid-19-induced transaction costs were utilized to gauge the pandemic's impact on unemployment rates. Seven developed countries and seven developing countries were separately scrutinized for this purpose. According to the outcomes of Yilanci and Gorus' (2020) panel causality test, Covid-19-induced transaction costs did not influence unemployment rates in developed countries. However, they significantly impacted unemployment rates in developing countries. These findings underscore the resource gap between developed and developing nations in tackling pandemic-related challenges. Policymakers should consider these economic disparities when devising strategies to alleviate the pandemic's effects.

Çavdar, Ozlem
Concrete structures designed prior to the implementation of modern building codes are still in use today. These structures are known for their inadequate design and poor performance during earthquakes. In this study, a performance analysis was conducted on an existing school structure in Istanbul, Turkey. The reasons for the damage were explored, and the structure was evaluated to determine the necessity for strengthening, the potential strengthening methods, and the appropriate comparison. Finally, recommendations were presented based on the available data from this study. The building was constructed in 1996 and has calculation reports and a static project. Linear and nonlinear methods were employed to determine the earthquake safety of structures after a mathematical model was created. The earthquake resistance of both the existing and retrofitting states of the school building was analyzed using linear and nonlinear analysis methods. The controlled damage limit could not be determined due to the high seismic intensity. A retrofit project has been devised for this low seismic performance building, comprising column jacketing, wrapping of beams with FRP, and the addition of shear walls.

Ericek Maraslioglu, Serife
According to the findings of the Turkish General Social Survey (TGSS), feelings of loneliness are more prevalent among young people. Due to the frequent changes in values, emotions and thoughts that characterise individuals during this period of life, it can be said that they are particularly vulnerable to loneliness. Existential loneliness, a deeper form of loneliness, is also referred to as ultimate loneliness. Potential triggers for young individuals to experience existential loneliness include meaninglessness and the inability to make oneself understood or express one's feelings. However, loneliness has been associated with various mental and physical health problems, there is insufficient research on individuals experiencing existential loneliness during adolescence. Against this backdrop, the present study aims to examine the mediating role of dysfunctional attitudes in the relationship between religiosity and existential loneliness in individuals in early adulthood. Ethical approval for the study was granted by the G & uuml;m & uuml;& scedil;hane University Scientific Research and Publication Ethics Committee on 28/05/2025 (approval number 2025/5). The study included 408 participants (294 women and 114 men) aged between 18 and 29. Data were obtained using the Religiosity Scale, the Existential Loneliness Scale , and the Dysfunctional Attitudes Scale. These were analysed using IBM SPSS AMOS and the PROCESS add-on module for SPSS. Correlation analysis revealed that religiosity was negatively associated with existential loneliness and dysfunctional attitudes, while existential loneliness and dysfunctional attitudes were positively associated with each other. Additionally, the analyses revealed that dysfunctional attitudes played a mediating role in the relationship between religiosity and existential loneliness. The mediation analysis conducted within the scope of the study was performed using the PROCESS macro (Model 4). Interventions targeting dysfunctional attitudes and promoting a healthier self-concept/self-image could be crucial in safeguarding young adults against existential loneliness. These results shed light on potential psychological mechanisms that explain the effect of religiosity on loneliness experienced by young people.

Yelboga, Alim; Özdemir, Hakan
Using data from the World Values Survey (2017-2021), this study examines the impact of factors such as ethical values, social norms, and perceived corruption on tax compliance, employing an ordered logistic regression analysis. The findings indicate that individuals' ethical values are the strongest determinant of tax compliance, whereas perceived corruption has a statistically significant but comparatively weaker effect. While a significant portion of the findings are consistent with existing literature, the study's clearer demonstration of the relative impact of ethical values compared to other factors constitutes a complementary contribution to the literature. Overall, the results confirm that tax compliance is shaped not only by economic incentives but also by individuals' values and perceptions. The findings demonstrate the importance of strengthening ethical values and social trust in enhancing voluntary tax compliance.

Dogan, Onur
This study aims to examine the occupational traumas experienced by occupational safety specialists following fatal, limb-loss, and serious injury-related workplace accidents, as well as the impact on their safety perceptions and the preventive strategies they develop. This research was conducted using a phenomenological approach, which is a type of qualitative research design. In-depth semi-structured interviews were carried out with 14 occupational safety experts working in various regions of Turkey. Criterion sampling was used to select participants. The data obtained were systematically analysed using thematic analysis. Interviews continued until data saturation was reached, and recurring patterns were observed. The research process and the reporting of findings were structured in accordance with the COREQ checklist. The study identified three main themes: occupational trauma, altered risk perception, and new safety strategies. These reflect specialistic psychological and professional changes following workplace accidents. The study offers insights into how occupational safety specialists adapt their policies and improve safety culture after serious accidents. It emphasises changes in precautionary approaches and their role in fostering safer workplaces. Key policy and cultural enhancement recommendations are also proposed.

Bingöl, Ozhan
PurposeThis study aims to propose a novel fractional-order neural network-based fixed-time sliding mode controller to address the challenges of chaotic satellite attitude control, synchronization and anti-synchronization. By integrating fractional-order dynamics and neural network-based estimation, the proposed approach enhances robustness and adaptability in stabilizing complex systems.Design/methodology/approachThe proposed control scheme introduces a novel sliding surface that leverages fractional calculus to improve convergence speed and control flexibility. A neural network is used to adaptively estimate unknown error dynamics, compensating for uncertainties in the system. The fixed-time stability property guarantees convergence within a predefined time, independent of initial conditions. Theoretical stability proofs and numerical simulations are conducted to validate the effectiveness of the proposed controller.FindingsThe results demonstrate that the proposed controller effectively stabilizes chaotic satellite attitude dynamics and ensures reliable synchronization and anti-synchronization. The approach exhibits strong robustness against system uncertainties and external disturbances while achieving fixed-time convergence.Originality/valueThis work advances the field by integrating fractional-order dynamics with a neural network-based adaptive mechanism in a fixed-time sliding mode control framework. The proposed method enhances convergence properties and robustness in controlling chaotic satellite attitude systems, providing a novel and effective solution for complex nonlinear dynamics.

BackgroundSystemic inflammation contributes to arrhythmogenesis in acute coronary syndromes, but its role in NSTEMI-related ventricular arrhythmias remains poorly defined. The pan-immune-inflammation value (PIV) is a novel composite biomarker reflecting immune and thrombotic activity derived from routine blood counts. This study aimed to assess the association between PIV and the risk of sustained VT/VF in NSTEMI.MethodsIn this retrospective cohort study, 1,788 NSTEMI patients who underwent percutaneous coronary intervention were analyzed. The primary endpoint was the occurrence of sustained VT or VF during hospitalization. PIV was calculated as (neutrophil x platelet x monocyte)/lymphocyte. Logistic regression, ROC analysis, Kaplan - Meier curves, reclassification indices (NRI, IDI), and restricted cubic spline modeling were used.ResultsVT/VF occurred in 34 patients (1.9%). Those with VT/VF had significantly higher PIV values (median 1132 vs. 329, p < 0.001). In multivariable analysis, PIV remained an independent predictor (OR: 1.356 per 1000 unit increase; 95% CI: 1.028-1.787; p = 0.031). The risk of VT/VF rose progressively across PIV quartiles (Q4 vs. Q1 OR: 4.0, p for trend < 0.001). Adding PIV to conventional predictors improved risk classification (NRI: +0.089; IDI: 0.007). Kaplan - Meier analysis showed significantly reduced arrhythmia-free survival in high-PIV tertiles (log-rank p < 0.001), and cubic spline modeling revealed a non-linear association with increased arrhythmic risk at higher PIV levels.ConclusionsElevated PIV is independently associated with malignant ventricular arrhythmias in NSTEMI. As an accessible biomarker, PIV may aid early arrhythmic risk stratification and guide clinical surveillance strategies.

Karakaya, Hanife; Colakoglu, Zafer; Acarer, Ahmet; Ozkurt, Ahmet
Objectives: The study aimed to develop a measurement method that yielded objective data for the clinical assessment of cervical dystonia using a Kinect camera system. Patients and methods: This double-blind, parallel-group method development study included 22 patients with cervical dystonia (3 males, 19 females; mean age: 47 years; range, 34 to 60 years) and 20 healthy individuals (13 females, 7 males; mean age: 32 years; age range, 22 to 65). Using cameras and a computer software, the head-neck postures of 40 healthy participants were recorded in the virtual environment. Using the device, 22 patients with cervical dystonia were examined both at rest and while moving with different parts of the body. Two different experts evaluated and scored the cases using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) and the Tsui scale. Results: A three-way comparison revealed interclass correlations between the coefficients of 0.799 (79.9%) and 0.784 (78.4%) for at rest and with movement, respectively. The two-way comparison of the experts revealed correlation coefficients of 0.717 (71.7%) and 0.692 (69.2%) for at rest and with movement, respectively. A three-way comparison of the device and Expert 1 and Expert 2 TWSTRS scores revealed interrater agreement values of 0.6 and 0.8 (good) and 0.6 and 0.8 (good) while at rest and with movement, respectively. A three-way comparison of the device and Expert 1 and Expert 2 Tsui scores revealed interrater agreement values of 0.6 and 0.8 (good) and 0.4 and 0.6 (moderate) while at rest and with movement, respectively. Conclusion: The newly developed system was a sensitive tool for use in the kinematic evaluation of patients with cervical dystonia and could prove beneficial in diagnosis and treatment follow-up.

Pala, Fahrettin; Görgün, Mehmet Ragip; Torusdag, Mustafa; Demirtas, Furkan; Barut, Abdulkadir
The current study explores the impact of global gold price uncertainty on the stock markets of the MIST countries: Mexico, Indonesia, South Korea, and T & uuml;rkiye. The study examined the crisis periods that started with the COVID-19 pandemic and continued with the Russia-Ukraine war, which caused uncertainty in gold and oil prices. Based on this, the study's data set consists of the daily closing prices between March 11th, 2020, and January 31st, 2023. The obtained data were analyzed using the Least Squares (ICC) and panel quantile regression (PQR) methods. There is a significant positive correlation between oil prices and oil volatility index with stock prices for the economies of T & uuml;rkiye, Indonesia, and Mexico, and a significant negative correlation between gold prices and gold volatility index with stock prices for developing countries. There is also a significant positive relationship between gold and oil prices and stock prices for the developed country, South Korea's economy. A significant negative correlation has also been proposed between gold and oil volatility indices and South Korean stock prices. This study provides a novel contribution to the literature by examining the impact of simultaneous global crises namely the COVID-19 pandemic and the Russia-Ukraine war-on the stock market indices of MIST countries through the lens of uncertainty in both gold and oil markets. While most existing studies focus on a single commodity or analyze crises in isolation, this research distinguishes itself by investigating the combined effects of two major global shocks and incorporating both price and volatility-based uncertainty indicators. The findings suggest that policymakers should develop country-specific and differentiated financial stability policies by taking into account the uncertainties in gold and oil markets during crisis periods.

Myosotis amoena Boiss. (Turkish name: Ho & scedil; boncukotu) is a perennial herbaceous plant that produces blue flowers during the spring. Phytochemicals, which are secondary metabolites distributed across plants, fungi, microorganisms, and even animal tissues, play crucial roles in health through their antioxidant and bioactive properties. Their antioxidant capacity largely arises from hydroxyl groups and aromatic ring structures that stabilize free radicals via electron delocalization. Enzyme inhibition is a therapeutic strategy in several diseases, including Alzheimer's disease (AD), where acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors are employed to manage symptoms. This study investigated the phytochemical composition (via LC-MS/MS), total phenolic content, antioxidant capacity, and AChE/BChE inhibitory effects of the ethanol extract of M. amoena using four in vitro methods. The CUPRAC assay demonstrated that M. amoena (1.070) exhibited higher antioxidant activity than Trolox (0.894), although its activity in FRAP, ABTS, and Fe3+ reduction assays was lower compared to standard antioxidants. The extract contained 53.03 mg GAE/g extract of total phenolics, with rosmarinic acid being the predominant compound (15.27 mg/g). Furthermore, the extract strongly inhibited AChE and BChE, with IC50 values of 3.9 and 19.8 mu g/mL, respectively. These findings highlight, for the first time, the significant bioactive potential of M. amoena as a natural source of antioxidants and cholinesterase inhibitors, supporting its prospective use in the prevention or management of neurodegenerative conditions.

Until 2016, two subspecies of Neurergus strauchii were identified; at this time, one more subspecies was described from Tunceli as N. s. munzurensis. However, this study mainly focused on morphological characters. We aim to test of Neurergus species, including N. s. munzurensis taxa by phylogenetic analysis, using partial base sequences of 12S rRNA and D-loop genes. For this purpose, we reconstructed Bayesian Inference and Maximum Likelihood trees with other Neurergus samples. According to the results, phylogenetic tree topologies demonstrate that N. crocatus was separated from the N. strauchii-N. barani lineage and the N. strauchii group have shown monophyly. Also, N. s. munzurensis showed higher genetic distances with N. barani (1.1%) and N. s. strauchii (0.8%) while genetic distances were only determined as 0.5% within N. barani and N. s. strauchii. N. s. munzurensis was found to be a genetically distinct taxon, following its previous morphological description. This study obtained the first evidence on better explaining the taxonomic status of N. s. munzurensis.
