- MakaleAçık Erişim2026Scopus SJRQ4Semantic Architecture and Knowledge Evolution of Endoscopic Submucosal Dissection Research: A Computational Bibliometric Analysis
Demir, Huseyin; Akar, Tuncay; Mertoglu, Suleyman; Tekinarslan, Merve
Aim: The overarching intellectual structure, dominant thematic clusters, and longitudinal evolution of the endoscopic submucosal dissection (ESD) literature have yet to be systematically mapped. This study aims to characterize the semantic and thematic architecture of ESD research through computational text analytics and to reveal latent structural patterns and temporal dynamics within this domain. Methods: A corpus of 1,000 peer-reviewed publications was processed through an eight-stage computational pipeline that incorporated word embedding-based semantic analysis, unsupervised clustering, Latent Dirichlet Allocation (LDA) topic modeling, inter-topic network analysis, and temporal trend modeling. The primary outcome was characterization of the semantic architecture of ESD research, whereas secondary outcomes included topic relationships, temporal evolution, and model performance metrics. Results: Semantic analysis revealed two dominant clusters: a technically oriented domain encompassing device innovation and procedural optimization and a clinically oriented domain addressing therapeutic outcomes, organ-specific protocols, and adverse event management. Topic modeling identified nine coherent thematic categories, with limited integration between technical and clinical research trajectories. Temporal analysis revealed a pronounced post-2024 shift toward upper-gastrointestinal applications, particularly esophageal and gastric ESD, with relative stagnation in colorectal investigations. The optimal semantic clustering solution achieved a silhouette score of 0.215, while the nine-topic LDA model demonstrated a coherence score of 0.39. Conclusion: This study provides the first data-driven macro-structural characterization of the ESD literature, revealing a persistent bifurcation between technical innovation and clinical application streams. These findings offer a strategic framework to help clinicians, investigators, and curriculum developers identify priority areas for advancement in therapeutic endoscopy.

Zaman, Tolga; Islamoglu, Ebrucan; Bulut, Hasan
This study addresses the challenge of outliers in sample surveys, a common issue that can distort results and lead to inaccurate conclusions. To tackle this problem, researchers have developed various robust regression techniques including least trimmed squares, least median of squares, least absolute deviations, Huber’s, Hample’s and Tukey’s maximum likelihood estimators, and Huber’s maximum likelihood estimator for location and scale estimators. We propose a new approach: minimum covariance determinant-based ratio estimators for estimating the population mean in sample surveys. To assess the performance of the proposed minimum covariance determinant-based estimators, we derive their mean square error expressions and determine the conditions under which they surpass existing estimators in efficiency. To validate our theoretical findings, we conduct a numerical illustration using real-world data and perform simulations with R-Programme software. The results demonstrate that our method effectively handles outliers and improves the overall accuracy of survey-based estimations, making it a valuable tool for researchers working with sample survey data.
- MakaleYalnız künye2026Scopus SJRQ3Challenge of existence: social anxiety in Finding Audrey
Demir, Nalan
Mental health problems affect individuals worldwide, and literature functions as a medium for both reflecting and shaping social understandings of these issues. Young adult (YA) novels that address mental health can raise public awareness, enhance mental health literacy, and support earlier diagnosis and more effective treatment. This study examines the representation of social anxiety disorder in Finding Audrey (2015) by Sophie Kinsella, focusing on the protagonist Audrey Turner. It analyses Audrey’s experience through her symptoms and treatment process, classifying symptoms into behavioural and cognitive-emotional categories. Behavioural symptoms include avoidance, limited eye contact, and physical reactions, while cognitive-emotional symptoms involve negative self-talk, shame, low self-esteem, negative self-perception, and diminished trust in others. These symptoms and the depicted therapeutic approaches are evaluated in relation to current psychological and psychiatric research. Overall, the novel presents social anxiety disorder in a realistic and psychologically coherent manner, aligning with findings in psychology and psychiatry.

Ayrancı, Vasıf Kubilay; Mzoughi, Mondher; Salum, Pelin; Zemzemoğlu, Tuba Eda Arpa; Erbay, Zafer
Microwave-assisted vacuum drying (MVD) is an emerging technology suitable for producing healthy snack foods, such as cheese snacks. This study aimed to produce a low-fat, low-salt, crunchy cheese snack using MVD. Low-fat, low-salt cheese slices were dried under seven different combinations of microwave power (5%–15%), vacuum level (220–300 Torr), and drying time (6.5–11 min), selected through preliminary trials. The resulting snacks were characterized by their physical properties and volatile compound profile. The results revealed significant differences in moisture content, water activity, bulk density, and volumetric/surface/cross-sectional expansion among the samples. Samples produced under high vacuum and long process time conditions exhibited the most favorable overall characteristics, including the lowest moisture, water activity, and density, alongside the highest volume expansion. These samples also showed a darker color and a superior crispy texture (higher fracturability with lower hardness, springiness, and chewiness). Twelve volatile compounds, with a profile limited by the low-fat content of the cheese, were detected. The TOPSIS analysis identified the sample produced under high vacuum conditions (dried at 10% power, 220 Torr, 10 min) as optimal. Practical Applications: This study provides a roadmap for producing crunchy, low-fat, and low-salt cheese snacks using microwave vacuum drying. For food manufacturers, the identified optimal conditions offer a process guideline to develop a healthier snack alternative with an appealing texture and color. The systematic TOPSIS-based evaluation method can be adopted for quality control and product development decisions. For consumers, the resulting product aligns with growing demand for nutritious, reduced-sodium convenience foods.

Palancı Ay, Özge; Aktaş, Songül
Objectives: This study examined the effect of breastfeeding education using the motivational interviewing technique on breastfeeding motivation, self-efficacy, and mother–infant bonding in mothers who gave birth vaginally. Methods: This randomized, controlled trial included 80 primiparous mothers. The experimental group received breastfeeding education with the motivational interviewing technique at four time points. Data were collected using Maternal Descriptive Information Form (MDIF), the Primiparous Breastfeeding Motivation Scale (PBMS), the Breastfeeding Self-Efficacy Scale (BSES), the Mother–Infant Bonding Scale (MIBS), and the Motivational Interviewing Importance and Confidence-Efficacy Rating Scale. Data were collected at three time points: immediately before training (pretest), 15 days following completion of the training (post-test), and 4 weeks thereafter (follow-up). Data were evaluated using Student’s t test, Mann–Whitney U test, analysis of variance, Friedman variance test, and intention-to-treat analysis. Results: In the post-test and follow-up evaluations, the experimental group had significantly higher mean scores than the control group in the “Value ascribed to breastfeeding” (p < 0.001 and p = 0.004, respectively) and “Midwife support” (p < 0.001 and p = 0.003, respectively) subdimensions of the PBMS as well as in “Motivational interviewing importance” (p < 0.005) and “Confidence-efficacy rating scale” (p < 0.001). During the follow-up period, the experimental group also showed significantly higher scores in the “Self-efficacy” subdimension (p < 0.001) and total mean scores of the BSES (p = 0.033) and MIBS (p = 0.002) than the control group. However, the “Expectation of success” subdimension score of the PBMS was not significant (p > 0.05). Conclusion: Breastfeeding education using the motivational interviewing technique enhances breastfeeding motivation (including values ascribed to breastfeeding, self-efficacy, and midwife support), breastfeeding self-efficacy, mother–infant bonding, and the importance and confidence-efficacy levels in breastfeeding. © The Author(s) 2026.

Arslan Burnaz, Nesibe; Baltacı, Cemalettin; İlyasoğlu, Huri
Toxic furanic compounds such as 5-hydroxymethylfurfural (HMF) and 2-furfural (F) can form during the processing and storage of non-alcoholic beverages (NABs). This study aimed to determine the levels of HMF and F in a wide range of NAB categories, including fruit juices and nectars, carbonated soft drinks, non-carbonated soft drinks, energy drinks, and coffee with milk drinks. The levels of HMF and F were determined using a validated analytical method. The HMF and F levels of the studied samples varied depending on the type of product. The coffee with milk drinks exhibited the highest levels, while the carbonated soft drinks exhibited the lowest. Notably, the HMF levels of most of the coffee with milk drinks exceeded 10 mg L−1. The findings provide novel insights into the presence of furanic compounds in NABs and emphasise the importance of raising consumer awareness regarding potential dietary exposure to furanic compounds, particularly from coffee drinks.

Özer, Şükrü; Odaci, Hatice
This study aims to explore the associations among relationship quality, cognitive flexibility, cognitive emotion regulation, and subjective well-being in married individuals in Turkey. Using a cross-sectional correlational design, we collected data from 1,013 married participants (mean age = 40.65; 52.5% male). Results indicated that relationship quality was positively associated with subjective well-being, cognitive flexibility, and adaptive emotion regulation strategies and negatively associated with maladaptive emotion-regulation strategies. Cognitive flexibility and adaptive emotion-regulation strategies were positively associated with subjective well-being, whereas maladaptive strategies were negatively associated. Mediation analyses revealed significant indirect associations between relationship quality and subjective well-being through cognitive flexibility and both adaptive and maladaptive emotion-regulation strategies. These findings highlight patterns of association among relational and cognitive-emotional variables in marital well-being and may inform future research and clinical practice.
- MakaleAçık Erişim2026Scopus SJRQ3Enhancing precision of low-cost detectors via machine learning for accurate mass attenuation coefficient estimation
Düzgün, İ.; Küçük, M.A.; Kaya, S.; Çelik, N.
Low-cost NaI(Tl) detectors are practical for gamma-ray spectrometry but their limited energy resolution can introduce systematic errors in mass attenuation coefficient measurements when scattered photons are included in the peak region. This study proposes a machine-learning correction framework that maps NaI(Tl)-derived attenuation coefficients to XCOM-based HPGe-equivalent reference values through a dimensionless correction factor. An EGS4/XCOM dataset of 756 model-development configurations, covering 18 atomic numbers, six monoenergetic photon energies, and seven collimator radii, was used to train twelve regression models and evaluate them over 60 randomized train–validation–test cycles. Sodium and Bismuth were withheld for external material-wise validation. Gaussian Process Regression with a Matérn 5/2 kernel provided the best overall testing performance. For the withheld materials, the correction reduced the mean deviation from XCOM references from 3.07% to 0.83%, supporting its use as a practical correction layer for low-cost attenuation measurements.

Kocak, Tevfik; Kocyigit, Emine; Ozbek, Yagmur Demirel
Background: Food neophobia, defined as the reluctance to try unfamiliar foods, reduces dietary diversity and quality in young adults. University students, often subjected to psychological discomfort including sadness, anxiety, and stress, may be especially susceptible to restrictive eating behaviors. This study examined the link be-tween psychological distress and food neophobia, focusing on the mediating role of food choice motives in Turkish students. Methods: A cross-sectional online survey was conducted among 801 Turkish university students (232 males and 569 females). The data collection included the Food Neophobia Scale (FNS), the Depression, Anxiety, and Stress Scale (DASS-21), and the Food Choice Questionnaire (FCQ). The body mass in-dex was calculated using self-reported anthropometric measurements. Statistical analyses comprised correlations, multivariable linear regression, and mediation mod-eling using Hayes’ PROCESS macro with 5000 bootstrap samples. Results: Food neophobia was positively associated with all DASS-21 subscales (p < 0.001). Regression analyses identified depression (p < 0.001), stress (p = 0.001), convenience (p = 0.001), and ethical concern (p < 0.001) as significant positive predictors, whereas natural con-tent showed a negative association (p = 0.046). Mediation analyses indicated that food choice motives partially explained the associations between psychological distress and food neophobia. Convenience and ethical concern consistently acted as mediators of risk, while natural content demonstrated a more complex role. Conclusions: Food neophobia among university students is influenced by both psychological distress and food choice motives. Depression and stress exert stronger effects than anxiety, with convenience and ethical concern functioning as consistent mediators.

Düzgün, İbrahim; Çelik, Necati; Kaya, Selim
The increasing use of ionizing radiation in medical, industrial, and nuclear applications necessitates the development of advanced and environmentally friendly shielding materials. In this study, the gamma-ray shielding performance of BaO-modified magnesium borophosphate glasses with compositions xBaO–30MgO–10P2O5–(50−x)B2O3–10Na2O (x = 0–35 mol%) was theoretically investigated. The radiation attenuation properties were evaluated over a wide photon energy range (59.54–2000 keV) using the WinXCOM database and Monte Carlo simulations based on the EGS4 code. Key shielding parameters, including mass attenuation coefficient (μ/ρ), half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), radiation protection efficiency (RPE), and gamma-ray kerma coefficients, were determined. The results indicate that increasing BaO content enhances the attenuation capability of the glass system, particularly in the low and medium photon energy regions, due to increased density and effective atomic number. A good agreement between WinXCOM and EGS4 results confirms the reliability of the applied theoretical approaches. These findings suggest that BaO-modified magnesium borophosphate glasses are promising candidates for radiation shielding applications.

Şan, Murat
Climate change can show different characteristics at low and high values of a time series, leading to non-monotonic trends. The Mann-Kendall (MK) and seasonal MK tests can only detect monotonic trends and ignore different behaviors in low and high value groups. To overcome this limitation, extending the recently proposed non-monotonic MK (NMK) test, the seasonal NMK (SNMK) test is proposed. The method was applied to four stations in Türkiye with four different climatic and topographic characteristics using monthly total precipitation data for the 1969-2020 for seasonal trend behavior. The results showed that while no significant trends were detected in entire time series, intra-seasonal and annual data, both monotonic and non-monotonic significant trends emerged in seasonal analyses. Especially in two stations, opposite changes in low and high values, increased seasonal variance and non-monotonic seasonal trends were observed. The test can be used for regional trend analysis by replacing seasonal data with regional data. It is also predicted that the SNMK test can be used as an effective decision support tool in areas with high seasonality such as water resources management, agriculture, energy planning and disaster management.

Ciminli, Alaattin; Aydin, Burak
This study aimed to identify distinct latent profiles of career anxiety among young adults and to examine the predictors of membership in these profiles by relating them to various factors, including academic unit and year of study. The data were collected from a sample of 509 young adults enrolled at universities in Türkiye, comprising 409 females (80.4%) and 100 males (19.6%). The instruments used for data collection included a personal information form, Career Anxiety Scale, Hope Scale, Perceived Social Support Scale, Perfectionism Scale, and the Coping Self-Efficacy Scale. Latent profile analysis (LPA) was employed to identify latent profiles, while multinomial logistic regression (R3STEP) analysis was conducted to examine the relationships between latent profile membership and sociodemographic variables. The results of the LPA revealed three distinct latent profiles: high anxiety and vulnerable (Profile 1), low anxiety and high psychosocial strength (Profile 2), and moderate group (Profile 3). The findings indicated that when Profile 1 was used as the reference group, academic unit type and class level did not significantly predict membership in Profile 2. However, vocational school status significantly predicted membership in Profile 3. When Profile 2 was used as the reference group, it was observed that both vocational school students and fourth-year students were significantly less likely to be members of Profile 3.

Kıranşan, Murat
This study reports a comprehensive evaluation of acetaminophen (ACT) photocatalytic degradation in aqueous media using hydrothermally synthesized Do-TAB/Clinoptilolite (Do-TAB/CNP), NiO nanoparticles, and a hybrid Do-TAB/CNP@NiO nanocatalyst. The prepared materials were systematically characterized by XRD, FT-IR, SEM-EDX, TEM, XRF, BET surface area, and BJH pore size analyses, confirming their crystalline structure, surface morphology, elemental composition, and porous features. The photocatalytic activity was investigated as a function of catalyst dosage, initial ACT concentration, solution pH, irradiation source, water matrix, and radical scavengers to clarify the degradation behavior and reactive species involved. Under optimal conditions, Do-TAB/CNP@NiO achieved 98.50% ± 0.75% ACT degradation within 120 min, whereas the maximum efficiency reached 99.92% ± 0.82% at 10 mg L−1 ACT under the same catalyst dosage. Kinetic analysis revealed pseudo–first–order behavior, with apparent rate constants (kapp) of 0.0061–0.0565 min−1 for catalyst dosage, 0.0117–0.0599 min−1 for ACT concentration, and 0.0218–0.0350 min−1 for water matrices. Radical scavenging tests verified the dominant contribution of reactive oxygen species and the synergistic interaction between NiO and Do-TAB-modified CNP. The hybrid catalyst exhibited stable reusability, with degradation efficiency decreasing from 98.50% to 89.68% after six cycles. Under optimized conditions, pharmaceutical degradation followed the order MET (99.90%) ' ACT (98.50%) ' SMX (88.45%) ' NAP (86.90%) ' CIP (83.89%) ' NAL (79.17%). Compared with NiO nanoparticles (70.34%), Do-TAB/CNP (63.65%), and raw CNP (54.46%), Do-TAB/CNP@NiO demonstrated markedly enhanced photocatalytic performance, indicating its strong potential for pharmaceutical wastewater treatment applications in water.

Akduman, Gul; Kurtbeyoglu, Emine
Purpose – The environmental, ethical and health issues associated with conventional meat production necessitate the exploration of cultured meat as an alternative protein source. This study aims to assess the psychological determinants and consumer segments of cultured meat among Turkish adults. Design/methodology/approach – The study was conducted using an online survey with 471 participants (66% male, mean age 28.4 ± 9.2 years), measuring awareness, willingness to try, risk–benefit evaluative orientation and attitudinal factors. An exploratory composite evaluative indicator, termed the risk-benefit evaluative index (RBEI) was constructed from seven concern questions, and standardized factor scores reflecting environmental–ethical (F1) and health–technology (F2) attitudes were calculated. Cluster analysis (k = 3) revealed three consumer segments: Supportive Optimists, Hesitant Pragmatists and Skeptical Resisters. Findings – While awareness of cultured meat was relatively high, willingness to try remained limited. Consumer acceptance was primarily associated with attitudinal dimensions, particularly environmental–ethical considerations and trust in health and technology, whereas demographic variables showed limited explanatory power. Segmentation analysis revealed three distinct consumer profiles with differing acceptance patterns. Research limitations/implications – The findings suggest that consumer acceptance is primarily shaped by multidimensional psychological evaluations, particularly environmental–ethical considerations and trust in health and technology. The study highlights a “high awareness–low acceptance” paradox and underscores the importance of communication strategies that address both perceived risks and benefits. By combining an exploratory composite evaluative indicator with factor-analytic attitudinal dimensions and consumer segmentation, this study provides a more comprehensive approach to understanding consumer acceptance and offers practical insights for promoting the adoption of cultured meat. Originality/value – This study provides one of the first comprehensive investigations of cultured meat acceptance among Turkish adults by integrating a risk–benefit evaluative index, attitudinal dimensions, and consumer segmentation within a single analytical framework. By combining an exploratory composite evaluative indicator (RBEI), factor analysis, and cluster analysis, the study identifies three distinct consumer segments and highlights the “high awareness–low acceptance” paradox in an emerging market context. The findings demonstrate that evaluative and psychological attitudes, particularly environmental–ethical considerations and trust in health and technology, are more influential than sociodemographic characteristics in shaping consumer acceptance, providing practical insights for communication strategies and policies promoting alternative protein adoption.

Ceylan, Tülay; Ceylan, Levent; Yılmaz, Coşkun; Badau, Adela; Küçük, Hamza
Background: Inspiratory muscle warm-up (IWU) has been hypothesized to enhance athletic performance by pre-activating respiratory muscles; however, evidence in professional natural male bodybuilders is scarce. The present study investigated the acute effects of IWU on One-Repetition maximum (1RM) bench press performance and pulmonary function. Methods: The present randomized controlled experimental study comprised 20 male athletes with an average training experience of 3.21 ± 1.44 years, who trained for more than 5 h per week and had participated in national or international competitions. At the commencement of the study, all participants underwent a series of pulmonary function tests (PFTs), measurements of maximal inspiratory and expiratory pressures (MIP and MEP), and a 1RM test. Following the initial assessments, which were conducted seventy-two hours prior, participants were randomly assigned to either the IWU group (n = 10) or the control (CON) group (n = 10). While the IWU group performed both inspiratory muscle warm-up and standard exercise warm-up, the CON group performed only the standard warm-up. Subsequent to the execution of the warm-up protocols, both groups were subjected to re-evaluation through the means of the 1RM test and respiratory parameter measurements. Results: The IWU group demonstrated a 5.96% greater enhancement in 1RM performance in comparison to the control group (p < 0.001). Furthermore, significant increases were observed in FVC, FEV1, and FEV1/FVC following IWU, with improvements of 2.57%, 2.44%, and 2.65%, respectively (p < 0.001). Furthermore, an additional 2.39% enhancement in MEP was identified in favour of the IWU group (p = 0.008). The alterations in MIP and PEF exhibited by the two groups were analogous, with no statistically significant disparities observed (p > 0.05). Conclusions: The present study has demonstrated that IWU has the capacity to rapidly enhance maximal strength and respiratory function in professional bodybuilders. Consequently, IWU can be advocated as an efficacious warm-up technique to augment exercise performance in bodybuilding athletes. Trial registration: This trial was registered at ClinicalTrials.gov under the title “Acute effects of inspiratory muscle warmup on muscular performance and pulmonary function in natural bodybuilders’’.

Unal, Cihan; Şahin, Selim
This study investigates health sciences students’ attitudes toward artificial intelligence (AI) and the implications for ethical awareness, clinical decision-making, and public health. A cross-sectional survey was conducted between April 27 and May 15 2025, with 668 students from five departments at Gümüşhane University, employing the validated Artificial Intelligence Attitude Scale, which measures benefits, risks, and use, alongside 12 binary-response items assessing ethical, clinical, and public health judgments. Descriptive statistics, t-tests, ANOVA, and logistic regression analyses were applied. Findings indicate that students perceive AI as highly beneficial (M = 4.05) but also associate it with notable risks (M = 2.52; where lower scores indicate a higher level of perceived risk due to reverse coding). Logistic regression analyses revealed that risk perception (reverse-coded; higher scores indicating lower perceived risk) was the most consistent predictor across all dimensions. Specifically, students with lower perceived risk were significantly more likely to reject concerns regarding patient privacy (OR = 2.55, 95% CI [2.03–3.21], p < 0.001), dismiss the idea that relying on AI instead of human expertise is problematic (OR = 1.57, 95% CI [1.25–1.96], p < 0.001), and reject the notion that AI systems may harm public health (OR = 2.52, 95% CI [1.98–3.20], p < 0.001). While participants endorsed AI’s potential in enhancing patient safety, chronic disease management, and preventive care, they expressed significant concerns about privacy, legal responsibility, and a potential weakening of patient–clinician communication. Gender, academic discipline, and prior AI use further differentiated attitudes. The results highlight a dual perception of AI as both an opportunity and a threat, emphasizing that successful integration in healthcare requires not only technical competence but also ethical, legal, and communicative safeguards.

This study investigates how productivity and productivity-intensive technologies affect energy consumption in selected EU countries from 1996 to 2021. Despite technological progress, fossil fuels still dominate, posing environmental and economic concerns. Using the AMG method, results show that multifactor productivity significantly reduces energy use, while productivity-intensive technologies offer smaller but meaningful reductions. In contrast to prior research linking technology to higher energy demand, this study highlights the importance of efficiency-focused innovation. Findings support the EU’s 2030 energy reduction target and suggest policymakers should prioritise productivity-intensive technologies, on-the-job training, and digital tools to decouple growth from energy consumption.

Accurate assessment of external radiation dose rates from 137Cs is essential for evaluating radiological risk in environmental and occupational settings. This study refines dose conversion coefficient calculations by incorporating depth-dependent soil density and addressing limitations in conventional methods that assume constant soil density. We calculated dose conversion coefficients for 137Cs in soil, considering both exponential and Gaussian distributions of activity concentration. Using two models, one with constant density and another with variable density as a function of depth, we compared dose rates to quantify the effect of soil density variations. Results indicate that dose rates are consistently higher when depth-dependent density is applied. The effect is more pronounced when 137Cs activity is distributed over larger depths (i.e., greater relaxation lengths) or when broader Gaussian distributions are considered. This suggests that assuming constant soil density may lead to underestimations of dose rates, especially in heterogeneous or compacted soils. Our findings emphasize the importance of accounting for density variability in dose calculations to enhance radiological risk assessments for areas contaminated with 137Cs.
