Demirağ, Hatice; Cin, Aynur; Hintistan, Sevilay
Objective: This study was conducted as a single-blind, randomized controlled parallel-group study with 50 elderly individuals to investigate the effect of foot bath on sleep quality. Methods: The data were collected using the “Elderly Information Form” and the “Pittsburgh Sleep Quality Index (PSQI)” between 1 May 2022-1 July 2022 at a State Hospital in Gümüşhane province. The elderly in the foot bath group were given a foot bath with 41-42°C water for 20 minutes 50 minutes before normal sleep hours. No application was made to the control group except for the administration of data collection tools. The data were analyzed with Chi-square, Friedman, Wilcoxon Sign, and Mann-Whitney U tests. Results: It was determined that at least one of the total PSQI measurements and median scores of all subcomponents obtained from the elderly in the foot bath group differed depending on time (P<.05). However, it was found that there was no statistically significant difference in the sleep latency (B2), sleep duration (B3), habitual sleep efficiency (B4) and sleep disturbance (B5) component measurements obtained from the elderly in the control group depending on time (P>.05). Again, All PSQI subcomponents and total PSQI scores, except for the subcomponent “Habitual Sleep Efficiency (C4)”, decreased throughout the application in the elderly in the foot bath group. Conclusion: As a result, a foot bath improved sleep quality in the elderly. In line with the findings from this study, it is recommended to compare the foot bath with multiple experimental groups for a longer period of time.

Çakmak, Seher; Uzun, Sevda; Demir Çam, Sevgi
This study aims to examine the burden of disease experienced by multiple sclerosis patients and to deeply examine the impact of the disease on sexual life. A phenomenological research design was used in this study. This qualitative research was conducted with 20 multiple sclerosis patients. Interviews were conducted individually and face-to-face. The data were analyzed using Colaizzi's phenomenological analysis method. Two main themes (effects of the disease and sexual life) and five sub-themes (physical effects, mental effects, social effects, problems related to sexual life, sexual issues, and coping) were identified in the analysis of the data. As a result of the study, it was determined that the patients experienced serious physical, mental, and social problems due to multiple sclerosis, and their sexual lives were also negatively affected. Individuals experience significant issues related to their sexual life due to multiple sclerosis. Since multiple sclerosis is a multifaceted disease, it is thought that professional evaluation of sexuality in patients, diagnosis of sexual dysfunctions, and taking timely measures are of great importance to improve the quality of life of multiple sclerosis patients.

Güzel, Melih
The short shelf life of bread can be attributed to changes in its textural and sensory properties, a process termed staling, and large amounts of bread residue and waste are generated daily. Because the main component of bread is starch, the use of bread wastes as a substrate for bacterial cellulose (BC) production can significantly contribute to valorisation and reuse of wastes. This study aimed to investigate the BC production potential of various stale breads, convert these wastes into usable forms for food and other industries, and increase their economic value. Stale breads were hydrolyzed with dilute acid, and BC-producing bacteria from Kombucha tea were isolated and identified as Gluconobacter oxydans MG2021 (GO). BCs were produced from bread hydrolysates with GO and Komagataeibacter hansenii GA2016 (KH), and their properties were examined. The results indicated that stale breads represented a good source for BC production, as high BC yields were obtained using GO (8.81%–25.02%) and all BCs had superior properties such as high crystallinity (75.96%–91.39%), thermal stability, liquid holding capacity, and fine fibers (40.16–85.39 nm). This study demonstrated that bread wastes could be used as a low-cost substrate for large-scale BC production, and the abundance of bread wastes demonstrated their potential as a resource for commercial BC producers.

Balci, Neslihan
Diosmin is a natural flavonoid obtained by dehydrating flavanone glycoside hesperidin. This study evaluated the inhibition effects of diosmin flavonoid on human carbonic anhydrases (hCA I and hCA II) and acetylcholinesterase (AChE) enzymes, which are linked to various health issues, and compared the results with standard drugs. The antioxidant potential was assessed using five assays, namely DPPH, ABTS, FRAP, CUPRAC and Fe3+ reducing assays. The results determined that diosmin didn’t exhibit strong antioxidant activity. Additionally, the inhibition effects of diosmin on hCA I, hCA II, and AChE enzymes were examined. It effectively inhibited hCA I and hCA II enzymes with Ki values of 3.84±0.63 nM and 15.64±1.90 nM, respectively (Table 1). For comparison, the Ki values of the standard drug AZA were 1.44 ± 0.32 nM for hCA I and 3.66 ± 0.25 nM for hCA II. On the other hand, diosmin effectively inhibited AChE enzymes with Ki values of 9.31±2.40 nM. The Ki values of the standard drug Tacrine was 6.22±1.95 nM for AChE. These findings suggest that diosmin may serve as a selective enzyme inhibitor, particularly for hCA I, but has limited antioxidant capacity. Diosmin exhibited relatively weak antioxidant activity compared to standard antioxidants.

Objective: In this study, it is aimed to analyze the determining factors on the import demand for wheat and corn, which have an important place in Türkiye's grain imports, with the "Apparently Unrelated Regressions" model. Material and Methods: The data set used in this study consists of annual data covering the years 2006-2021. Stata program was used to analyze the data used in the study. Since Stata or Eviews programs do not provide the Standardized Beta (β) coefficient, statistical analyzes were performed using the formula in Microsoft Excel (β=B*SSXi / SSY). Results: Only the one-year delayed value of wheat imports, which is one of the explanatory variables in the wheat import model, was found to be significant, according to the study's findings. In terms of factors influencing corn import demand, similar results were obtained. Only total corn consumption was found to be statistically noteworthy among the explanatory variables in the corn import model. Conclusion: Based on these findings, wheat imports are influenced by changes in wheat imports from a year ago, while corn imports are influenced by changes in total corn consumption. Based on Türkiye's current structure and the findings obtained, it is understood that the country may continue to maintain its position as an importer of wheat and corn in the future.

Duran, Celal; Ozeken, Sengul Tugba; Seker, Serdal; Ozdes, Duygu
In the present research, a novel magnetic adsorbent was developed via the sol–gel method by coating CuFe2O4 nanoparticles on biochar sourced from brewed tea waste. The synthesized adsorbent was utilized for the removal of Ni(II) ions from aqueous media. The adsorption efficiency of Ni(II) ions was assessed under crucial experimental conditions such as initial solution pH, contact time, adsorbent dosage, and initial Ni(II) concentration. The adsorbent exhibited rapid adsorption kinetics, achieving equilibrium in approximately 15 min, and maintained high efficiency across a wide pH range. Adsorption experiments were conducted for Ni(II) solutions at their natural pH (5.6) to minimize chemical usage and enhance process simplicity. An impressive maximum adsorption capacity of 232.6 mg g−1 was recorded, outperforming many previously reported adsorbents. Furthermore, desorption studies demonstrated nearly 100% recovery of Ni(II) ions using 1.0 M HCl solution, indicating excellent regeneration potential of the adsorbent. Additionally, the prediction performance of an artificial neural network (ANN) model was evaluated to predict Ni(II) removal efficiency based on experimental variables, showing strong agreement with experimental data. Isotherm and kinetic models were also applied to the data to estimate the adsorption mechanisms. These findings demonstrate the promise of CuFe2O4-modified tea waste biochar for sustainable water treatment applications.

Aydin, Sefa; Melek, Mesut; Gökrem, Levent
Nowadays, brain–computer interface (BCI) systems are frequently used to connect individuals who have lost their mobility with the outside world. These BCI systems enable individuals to control external devices using brain signals. However, these systems have certain disadvantages for users. This paper proposes a novel approach to minimize the disadvantages of visual stimuli on the eye health of system users in BCI systems employing visual evoked potential (VEP) and P300 methods. The approach employs moving objects with different trajectories instead of visual stimuli. It uses a light-emitting diode (LED) with a frequency of 7 Hz as a condition for the BCI system to be active. The LED is assigned to the system to prevent it from being triggered by any involuntary or independent eye movements of the user. Thus, the system user will be able to use a safe BCI system with a single visual stimulus that blinks on the side without needing to focus on any visual stimulus through moving balls. Data were recorded in two phases: when the LED was on and when the LED was off. The recorded data were processed using a Butterworth filter and the power spectral density (PSD) method. In the first classification phase, which was performed for the system to detect the LED in the background, the highest accuracy rate of 99.57% was achieved with the random forest (RF) classification algorithm. In the second classification phase, which involves classifying moving objects within the proposed approach, the highest accuracy rate of 97.89% and an information transfer rate (ITR) value of 36.75 (bits/min) were achieved using the RF classifier.

Altundaş, Suna; Tanış, Abdulsamed
Recent earthquakes have adversely affected human life, highlighting the necessity of identifying structural and ground conditions to assess risky areas and mitigate potential damage from future seismic events. Gümüşhane, the designated study area, is susceptible to the impacts of a possible earthquake due to its proximity to the North Anatolian Fault Zone (NAFZ). Accordingly, vertical electrical sounding (VES), multi-channel analysis of surface waves (MASW), and microtremor methods were employed in the central district of Gümüşhane to characterize local ground conditions and to evaluate the resonance hazard potential arising from the interaction between structures and the underlying soil. Dominant period (T0) and frequency (f0), spectral amplification (A0), soil index of vulnerability (Kg), average S wave velocity for 30 m depth (Vs30), ground type, and soil-structure resonance hazard potential were determined. For the study area, f0 values between 1.32–8.91 Hz (T0 values varied between 0.11–0.76 s), A0 values between 0.93–7.63 according to horizontal/vertical spectral ratio (HVSR) analysis, and Vs30 values were between 390–886 m/sec to MASW. As a result of the evaluation of microtremor measurements made in all buildings using the floor spectral ratio (FSR) technique, the soil-structure potential resonance hazard was found to be low. The present study, conducted in Gümüşhane, examined the subject of soil-structure interaction. In the process of planning new residential areas, it is imperative to ensure the reliability of construction based on the local ground conditions. Furthermore, it is essential to determine the risk status of buildings in relation to potential earthquake movements.

Şimşek, Tugçe; Şimşek, Ahmet Bahadir
This chapter focuses on the use of sentiment analysis in the handling of employee experience. When organisations start thinking about the experience of their employees as a factor that influences performance and turnover, sentiment analysis provides a quantitative way of measuring emotions, satisfaction and engagement of employees. This chapter attentions on several NLP techniques that can be employed in the analysis of the employee feedback which include tokenization, stop- word removal and vectorization. It also looks at how other machine learning models such as Naive Bayes, Support Vector Machines, and Long Short- Term Memory can be used to categorize emotions as positive, negative, or neutral. In addition, the problem of language, culture, and data bias is described, and the ways to solve them are also described. The future potential of the real- time emotion analysis and the use of sentiment data along with the organizational KPIs for improving the management of employees' experience is depicted.

- MakaleAçık Erişim2025Scopus SJRQ3New Numerical Solutions for Caputo–Fabrizio Fractional Differential Multidimensional Diffusion Problems
Şahin, Yasin; Merdan, Mehmet
This study examined the multidimensional fractional diffusion equations that characterize the density dynamics in a diffusing medium utilizing the exact and analytical Aboodh transform decomposition method (ATDM). The Caputo–Fabrizio (CF) derivative is utilized to account for the fractional derivative that is being employed here. The suggested method handles nonlinear terms by combining the Adomian decomposition method (ADM) with the Aboodh transform (AT) and Adomian polynomials. Since the AT can only be applied to linear equations, ADM is a helpful technique for estimating solutions to nonlinear differential equations. In nonlinear systems, multidimensional diffusion problems which account for the production of stripes in two-dimensional systems are important. Additionally, we used MATLAB to compute numerical and graphical data that illustrate how the close-form analytical solution compares to the precise solution. Promising and appropriate for addressing multidimensional diffusion problems with fractional derivatives are the obtained results. The key benefit is that our devised approach does not depend on presumptions or constraints on variables that skew the actual issue. Overcoming fluctuating constraints that can make it difficult to discover the answer and represent the problem depends much on this technique. In the domains of science and technology, the approach presented in this work offers exceptional computational accuracy and convenience of use for analyzing and resolving intricate phenomena associated with CF fractional nonlinear partial differential equations.

Köseoğlu, Ali; Şahin, Rıdvan; Demir, Ümit
The Dempster–Shafer evidence theory is a very practical concept for handling uncertain information. The foundation of this theory lies in the basic probability assignment (BPA), which exclusively accounts for the degree of support attributed to focal elements (FEs). In this study, neutrosophic evidence sets (NESs) are defined to introduce additional probabilistic measures, aimed at addressing the uncertainty, imprecision, incompleteness, and inconsistency present in real-world information. The basic element of NESs is a neutrosophic basic probability assignment (NBPA), which consists of three components. The truth degree of FEs is represented by the first BPA, the second BPA represents the indeterminacy degree of FEs, and the last BPA characterizes the falsity degree of FEs. In NESs, each support degree of FEs is shown separately without any limitation. Therefore, the general concept of NESs is broader compared to traditional evidence sets and intuitionistic fuzzy evidence sets. Unlike the neutrosophic set (NS), the NBPA method assigns truth-support, uncertainty-support, and false-support degrees, as well as these support degrees, to single and multiple subsets in a discriminative framework. This paper aimed to develop some information measures for NESs, such as neutrosophic Deng entropy (NDE), neutrosophic cosine similarity measure, and neutrosophic Jousselme distance. Then, an improved method based on NDE and neutrosophic cosine similarity measure was established to combine contradictory evidence to increase the influence of reliable evidence on the one hand and to reduce the influence of unreliable evidence on the other hand. Finally, a case involving sensor data integration for target identification was studied to highlight the importance of these innovative ideas. The numerical example demonstrates that the proposed method provides more reliable and superior fusion performance compared to classical models, particularly in scenarios involving high conflict and uncertain information. However, the effectiveness of the method is partially influenced by the structure of the similarity matrix and the entropy parameters, which necessitates careful parameter tuning to achieve optimal results. These limitations are explicitly highlighted to serve as a guide for future improvements and broader applications of the method.

Background: Psoriasis is a chronic inflammatory disease that can be influenced by nutritional status and dietary habits. In particular, adherence to the Mediterranean diet, known for its anti-inflammatory properties, is increasingly being investigated in relation to disease severity and nutritional status. Aims: This case–control study, including 50 psoriatic patients and 40 healthy controls, aimed to examine the correlation between adherence to the Mediterranean diet and disease severity, nutritional status, and disease presence in patients with psoriasis. Methods: The clinical severity of psoriasis was assessed using the Psoriasis Area and Severity Index (PASI) score. Anthropometric measurements were taken, and body composition was determined using bioelectrical impedance analysis. All participants’ Mediterranean Diet Adherence Screener (PREDIMED) scores and 24-h food consumption records were evaluated. Results: The body weight (BW), waist circumference (WC), hip circumference (HC), and fat mass (FM) values of psoriatic patients were found to be significantly higher than those of the healthy control group (p < 0.05). The PREDIMED score of psoriatic patients was found to be significantly lower than that of the control group (p < 0.001). A negative correlation was observed between the PREDIMED score and BW, FM, and HC (p < 0.05). PASI levels decreased as PREDIMED scores increased (r = −0.314, p = 0.048). According to logistic regression analysis, after adjusting for age and sex, the likelihood of being healthy was approximately 6.363 times higher in those with high adherence to the Mediterranean diet (p < 0.001). Conclusion: When psoriatic patients were compared with healthy controls, significant differences were observed in PREDIMED scores. Notably, greater adherence to the Mediterranean diet was associated with reduced disease severity, suggesting a potential mitigating effect even in the presence of obesity.

Background: Nurses are among the most interactive professionals in society, providing both care and psychosocial and psychotherapeutic interventions for individuals with mental health issues. Nurse-centred approaches have demonstrated a positive impact on addressing mental health issues. Aim: This study aimed to evaluate the effectiveness of psychosocial and psychotherapeutic interventions administered by nurses in managing mental health issues. Methods: For this meta-analysis, data were gathered through a comprehensive search of databases, including PubMed, Web of Science, EBSCOhost, Google Scholar and the YÖK Thesis Center, with no restrictions on publication year. Following the review process, a total of 25 studies were included in the analysis. The PRISMA checklist was employed to guide our study. Results: The meta-analysis revealed that interventions implemented by nurses in the context of mental health were effective. Specifically, the psychosocial and psychotherapeutic interventions significantly reduced depression levels in individuals (SMD: −0.918, 95% CI: −1.350 to −0.486; Z = −4.161; p < 0.05) and anxiety levels (SMD: −0.61, 95% CI: −1.190 to −0.029; Z = −2.59; p < 0.05). Additionally, these interventions were associated with an improvement in individuals' quality of life (SMD: 0.673, 95% CI: 0.303–1.403; Z = 3.56; p < 0.05). Conclusion: Nurses can play a pivotal role in addressing mental health issues, effectively contributing to the reduction of anxiety and depression levels while enhancing the overall quality of life for individuals.

The 6 February 2023 Mw 7.7–7.6 Kahramanmaraş earthquake sequence has significantly impacted the East Anatolian Fault zone, including the city of Malatya and its immediate surroundings. In addition to the aftershocks of February 2023, the Mw 5.9 Kale earthquake that occurred on October 16, 2024, further underscores the ongoing seismic activity in the region. This study analyzes the distribution of b-values derived from a comprehensive dataset comprising 14,549 earthquakes and the Coulomb stress variations associated with the aftershocks of the February 2023 sequence and the Kale earthquake. The primary objective of this analysis is to enhance the understanding of the tectonic setting that contributed to the occurrence of the Kale earthquake. The findings indicate that the low b-values and stress transfer through the Pütürge segment toward the unnamed fault near Kale are significant contributing factors to the occurrence of the Kale earthquake. Additionally, positive stress variations from Doğanşehir to Malatya’s city center suggest a potential fault oriented toward the city center that may increase the current earthquake hazard. Furthermore, the distribution of seismic events around Malatya suggests a possible barrier supported by previous magnetic data analysis between Malatya and Kale. Lastly, the observed stress variations for the Kale earthquake indicate the likelihood of upcoming seismic events in both the northeast and southwest directions of the Kale.

Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model. The report reviews the experimental opportunities offered by the staged implementation of FCC, beginning with an electron-positron collider (FCC-ee), operating at several centre-of-mass energies, followed by a hadron collider (FCC-hh). Benchmark examples are given of the expected physics performance, in terms of precision and sensitivity to new phenomena, of each collider stage. Detector requirements and conceptual designs for FCC-ee experiments are discussed, as are the specific demands that the physics programme imposes on the accelerator in the domains of the calibration of the collision energy, and the interface region between the accelerator and the detector. The report also highlights advances in detector, software and computing technologies, as well as the theoretical tools/reconstruction techniques that will enable the precision measurements and discovery potential of the FCC experimental programme. The content and structure of this report are guided by the scope and priorities defined in the mandate of the FCC Feasibility Study. It is therefore not intended to serve as an exhaustive review of the full physics potential of FCC. Several topics, already covered in earlier reports such as the FCC CDR, are not reiterated here or are addressed only briefly, in alignment with the study's focus. This volume reflects the outcome of a global collaborative effort involving hundreds of scientists and institutions, aided by a dedicated community-building coordination, and provides a targeted assessment of the scientific opportunities and experimental foundations of the FCC programme.

In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. This report describes the FCC integrated programme, which consists of two stages: an electron-positron collider (FCC-ee) in the first phase, serving as a high-luminosity Higgs, top, and electroweak factory; followed by a proton-proton collider (FCC-hh) at the energy frontier in the second phase. The FCC-ee is designed to operate at four key centre-of-mass energies: the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold-each delivering the highest possible luminosities to four experiments. Over 15 years of operation, FCC-ee will produce more than 6 trillion Z bosons, 200 million WW pairs, nearly 3 million Higgs bosons, and 2 million top anti-top pairs. Precise energy calibration at the Z pole and WW threshold will be achieved through frequent resonant depolarisation of pilot bunches. The sequence of operation modes between the Z, WW, and ZH substages remains flexible. The FCC-hh will operate at a centre-of-mass energy of approximately 85 TeV-nearly an order of magnitude higher than the LHC-and is designed to deliver 5 to 10 times the integrated luminosity of the upcoming High-Luminosity LHC. Its mass reach for direct discovery extends to several tens of TeV. In addition to proton-proton collisions, the FCC-hh is capable of supporting ion-ion, ion-proton, and lepton-hadron collision modes. This second volume of the Feasibility Study Report presents the complete design of the FCC-ee collider, its operation and staging strategy, the full-energy booster and injector complex, required accelerator technologies, safety concepts, and technical infrastructure. It also includes the design of the FCC-hh hadron collider, development of high-field magnets, hadron injector options, and key technical systems for FCC-hh.
