The purpose of this study is to determine the prevalence and causes of emotional and behavioral problems in children whose parents have cancer.
Shielding efficiency of iron doped tincal: a first-principles study
(Elsevier B.V., 2026) Duru, İzzet Paruğ; Özuğurlu, Ersin; Arda, Lütfi
The idea of shielding has been popular for decades as a way to reduce unwanted radiation in a variety of applications, especially in the areas of security and health. Fe-doped tincal nanoparticles were examined in this article as a possible option for this use. Density functional theory (DFT) was used to calculate the dielectric function of Fe-doped tincal and shielding efficiency (SE). Fe-doped tincal structures were subjected to geometry optimization through the substitution of Fe at particular boron sites. After determining the formation energy to evaluate stability, the optical characteristics were calculated. The process was repeated for collinearly ordered ferromagnetic (FM) and antiferromagnetic (AFM) states. Considered structures obeyed the AFM state. On the other hand, low conductivity is indicated by the Fermi level electronic density of states (DOS). While bare tincal has a large indirect band gap (∼5eV), the band gap was almost nonexistent in both doped examples. The electromagnetic shielding efficiency ratings were determined to be extremely poor for all setups. Except for the low-frequency band, no discernible variations in SE were found between various configurations and photon polarizations. Significant variations were found for interactions with low-energy photons, especially in the ultraviolet spectrum.
Effect of channel geometry on the performance of an electrostatic precipitator: a comparative numerical study
(MDPI, 2026) Kılıç, Halil; Konuk Ege, Gözde; Temiz, İsmail; Genç, Garip; Akay Sefer, Özge; Sefer, Ahmet
This study presents a numerical investigation of the influence of channel geometry on electrohydrodynamic (EHD) processes governing particle transport in electrostatic precipitators (ESPs). A conventional rectangular channel is compared with concave configurations using a coupled multi-physics model that accounts for gas flow, electric field distribution, ion transport, and particle migration across a wide particle-size range. The results show that geometric modification significantly alters ion transport and charge distribution within the ESP channel. Compared with the rectangular configuration, the concave profile enhances ion penetration and particle charging, leading to improved collection efficiency across the entire particle-size range. The improvement is particularly pronounced near the minimum-efficiency region for submicron particles. Specifically, near 0.1 mu m, the collection efficiency increases from approximately 30% in the rectangular channel to approximately 50% for the higher-contraction concave configuration, representing an improvement of nearly 20 percentage points. A comparison with a Venturi-like contraction further shows that abrupt geometric contraction produces localized space-charge accumulation and reduces the effective charging region. In contrast, smooth concave shaping promotes a more distributed electrostatic interaction region, resulting in improved particle collection performance.
Artificial intelligence anxiety among employees: the moderating role of resistance to change in the effect of AI anxiety on innovative behavior
(ADAMOR Toplum Araştırmaları Merkezi, 2025) Özdemir, İsmail
Artificial intelligence (AI), which offers significant opportunities today, has fundamentally impacted numerous elements, from the way businesses operate to the employee profile. While AI contributes to growth through its efficiency, speed, and cost advantages, these developments also create anxiety, unease, and worry in many employees. On the other hand, individuals with high levels of innovative behavior are expected to perceive AI as an opportunity rather than a threat and experience less anxiety. However, the level of psychological resistance employees develop against technological transformation in organizations influences this relationship. This research aims to analyze how anxiety about AI affects innovative behavior and to examine the moderating effect of resistance to change within this dynamic. It focuses on employees in financial services, technology, manufacturing, and service sector organizations operating in Istanbul. No previous research has been found in the literature that addresses these three concepts together. The study used demographic information from 281 participants and data obtained through a survey consisting of three different scales. Descriptive statistics, reliability analysis, validity, normality assessment, Pearson correlation analysis, and regression analysis were applied to analyze the data. The study results revealed that AI anxiety had a significantly negative effect on employees' innovative behavior (β = -0.54, p < 0.001), resistance to change served as a moderator in the relationship between AI anxiety and innovative behavior (β = -0.09, p = 0.121), and financial services and technology sectors exhibited higher AI anxiety (M = 3.45, M = 3.38) than manufacturing (M = 2.98) and service (M = 3.12) sectors.

Bu durum bu çalışmanın özgün yanını oluşturmaktadır. Ölçeğin ego sörfü davranışında bulunma ihtimali olan meslek gruplarında kullanılabileceği, bu konuda alana rehberlik edeceği öngörülmektedir.
Duygusal emek ve iş tatmini: seramik sektöründe ampirik bir araştırma
(İstanbul Nişantaşı Üniversitesi, 2025) Özdemir, İsmail
Bu çalışma, İstanbul ilindeki seramik sektörü çalışanlarının duygusal emek ve iş tatmini algıları arasındaki ilişkiyi incelemeyi amaçlamaktadır. Günümüz rekabetçi iş ortamında, çalışanların duygusal ifadelerini işin gerekliliklerine göre düzenlemesi anlamına gelen duygusal emek, hem çalışanların psikolojik iyi oluşları hem de iş tatminleri üzerinde önemli etkilere sahiptir. İş tatmini ise, örgütsel performans ve çalışan bağlılığı açısından kritik bir faktördür. Bu araştırmada, 358 seramik sektörü çalışanından elde edilen veriler kullanılarak korelasyon ve regresyon analizleri yapılmıştır. Bulgular, duygusal emek ile iş tatmini arasında pozitif ve anlamlı bir ilişki olduğunu göstermektedir (r = 0.254, p < 0.001). Ayrıca, demografik değişkenlerin (cinsiyet, eğitim düzeyi, medeni durum ve iş pozisyonu) iş tatmini üzerinde anlamlı etkilere sahip olduğu tespit edilmiştir. Moderasyon analizi sonuçları, iş tecrübesinin duygusal emek ve iş tatmini arasındaki ilişkide düzenleyici rol oynadığını ortaya koymuştur. Bu çalışma, seramik sektöründeki insan kaynakları yönetimi uygulamalarına ve çalışan refahına yönelik stratejilerin geliştirilmesine katkıda bulunmayı hedeflemektedir. Araştırma bulguları, sektör yöneticilerinin çalışanların duygusal emek süreçlerini destekleyici politikalar geliştirmesi gerektiğini göstermektedir. Gelecekte yapılacak araştırmaların, duygusal emek ve iş tatmini ilişkisini etkileyebilecek diğer potansiyel değişkenlerin de modele dahil edilerek daha kapsamlı yapılması önerilmektedir.
A deep learning approach to document recovery: high performance with denoiseU-net
(Afyon Kocatepe University, 2025) Turan, Salih Can; Çıplak, Zeki; Sarıkaş, Ali; Yıldız, Kazım
Image denoising, a crucial task in image processing, has consistently faced challenges despite ongoing research efforts. In this study, a dataset was created by extracting 20,000 images from 60 public sources, including scanned or digitized documents. Each image was verified to contain at least one of the following: plain text, image, table, or mathematical expression. Common types of noise, including random black and white pixels, Gaussian blur, gray areas, speckle noise, random directional lines, Poisson noise, and salt-and-pepper noise, were applied to the images. To create the test set, each of the seven types of noise was individually added to 500 images excluded from the dataset, resulting in a balanced test set of 3,500 images. The complete dataset consists of 23,000 images, with a training-to-test ratio of 5:1. Specifically, our proposed DenoiseU-Net model aims to recover noisy scanned documents and performs effectively across various content types, such as tables, images, mathematical equations, and text. Experimental results show that the average precision, recall, and F1-score of DenoiseU-Net on the test set are 99.36%, 99.59%, and 99.48%, respectively. In addition to these evaluation results, the average SSIM and PSNR values, which are commonly used parameters to assess image quality, were obtained as 0.9657 and 40.28 dB, respectively. The primary objective of this study is not to demonstrate superior performance over state-of-the-art (SOTA) methods, but rather to evaluate how deep learning models, such as the proposed DenoiseU-Net, perform on medium-scale or small-scale datasets in practical scenarios.
The effect of postmenopausal therapeutic interventions on sexual function: a meta-analysis study
(National Scientific Medical Center, 2026) Yücetürk, Sibel; Özçalkap, Nurten; Çuvadar, Ayşe; Çuvadar Baş, Yeter
Aim: The purpose of this study is to identify how therapeutic interventions after menopause affect sexual function. Methods: For this study, research was conducted by screening studies in PubMed, Web of Science, EBSCOhost, Google Scholar, and YOK Thesis Center databases from May to July 2024. After reviewing the studies, five studies were included in the meta-analysis. The quality assessment of the studies was conducted using a quality assessment tool prepared by The Joanna Briggs Institute, according to Randomized Controlled Trials and Quasi-Experimental design studies. CMA Version 2 was used for data synthesis. The data were synthesized using meta-analysis and narrative synthesis methods. Results: According to the results of the meta-analysis, therapeutic interventions applied during the postmenopausal period were found to not be effective on sexual function (SMD: 1.056, 95% CI:-0.171 to 2.282; Z=1.686, p=0.092, I2=97.827%). These findings indicate that, when all intervention types are evaluated together, there is no statistically significant overall improvement in postmenopausal sexual function and that the results are highly heterogeneous across studies. However, subgroup analyses revealed that pelvic floor muscle training (PFMT) demonstrated a strong and statistically significant positive effect on sexual function in women with sexual dysfunction (p < 0.000), suggesting that the effectiveness of interventions varies according to intervention type. From a clinical perspective, this finding indicates that PFMT may represent a practical and targeted non-pharmacological option for improving sexual function in postmenopausal women, despite the absence of a significant overall pooled effect. Conclusion: While pelvic floor muscle training (PFMT) appears to be a promising intervention for improving postmenopausal sexual dysfunction, this finding is based on limited evidence and should be interpreted with caution. Given the variability in intervention types and study quality, further high-quality randomized controlled trials are needed to evaluate the comparative effectiveness of PFMT and other therapeutic approaches, as well as their potential combinations, in order to establish more definitive conclusions.

Nomophobia and netlessphobia: implications for psychological resilience and happiness
(Routledge, 2025) Karagöz, Yalçın; Filiz, Mustafa; Karaşin, Yusuf; Kuzgun, Şerife
This study aims to examine the effects of individuals' perceptions of nomophobia and netlessphobia on psychological resilience and happiness, and to determine the effect of psychological resilience perceptions on happiness. The study included 537 participants aged 18 years and over, working in either the public or private sector. Data were collected online using scales measuring nomophobia, netlessphobia, psychological resilience and happiness. Path analysis, t-tests and ANOVA tests were carried out based on the distribution of the collected data. The results indicate that individuals' perceptions of nomophobia (M = 4.06, SD = 1.25) significantly affect their perceptions of psychological resilience (M = 2.68, SD = 0.81), but have no effect on their perceptions of happiness (M = 2.61, SD = 0.86). Conversely, perceptions of netlessphobia (M = 3.78, SD = 0.84) significantly influence both psychological resilience and happiness. This study shows that digital anxiety affects psychological resilience and happiness. Specifically, nomophobia negatively affects psychological resilience but has no significant effect on happiness, whereas netlessphobia significantly affects both.
Evaluating bariatric surgery in patients aged 60 years and older: a retrospective multicenter comparison of sleeve gastrectomy and roux-en-Y gastric bypass
(Mary Ann Liebert Inc., 2026) Dalkılıç, Muhammed Said; Yüce, Kenan; Zapater, Christophe Adil Fernandez; Özdemir, Neslihan; Kovancı, Hafize; Oumar, Mahamat Bechır Saleh; Şişik, Abdullah
Background: This study aimed to compare the safety and efficacy of laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) in patients aged 60 and older, focusing on postoperative weight loss, improvement in obesity-related comorbidities, and perioperative outcomes. Methods: This was a retrospective analysis of data from three bariatric surgery centers with surgeries performed between January 2019 and September 2024. The study included patients aged >= 60 years who underwent either LSG or RYGB. The primary outcome was the comparison of weight loss metrics (excess weight loss [%EWL] and total weight loss [%TWL]) between LSG and RYGB. Secondary outcomes included the remission or improvement of type 2 diabetes mellitus (T2DM) and hypertension (HTN), 30-day postoperative complications, operative time, and length of hospital stay. Results: A total of 168 patients aged >= 60 who underwent LSG (n = 130) or RYGB (n = 38) were included. Both procedures resulted in similar weight loss outcomes, with a median %EWL of 58.6% for LSG and 61.2% for RYGB. The median %TWL was 23.1% for LSG and 26% for RYGB, with no significant differences between the groups (P = .275). The operative time was significantly shorter for LSG (60 minutes versus 110 minutes for RYGB, P < .001), and LSG patients had a shorter hospital stay (2 versus 3 days, P < .001). The 30-day complication rate was low for both groups, with no significant difference in complications between LSG and RYGB. Regarding comorbidity resolution, 90.7% of patients with T2DM and 93.6% with HTN experienced improvement or remission. Complete remission was achieved in 39% of all T2DM cases (37.5% in LSG, 42.9% in RYGB) and in 33% of all HTN cases (33.3% in LSG, 31.6% in RYGB), with no statistically significant differences between the groups. Conclusions: Bariatric surgery appears safe in older adults when guided by careful patient and procedure selection through multidisciplinary assessment. Both LSG and RYGB yielded comparable weight loss and remission outcomes for T2DM and HTN in this population.

(Karger, 2026) Çalışır Kundakçı, Şule; Öz, Tuğba; Karaşin, Yusuf; Karagöz, Yalçın
Introduction: The aim of this study was to develop a psychometric measurement tool to assess beliefs regarding complementary and alternative medicine and to ensure its validity. Methods: For the purpose of the study, sample of 735 people was reached between December 2023 and April 2024. During the scale development process, exploratory factor analysis was first conducted using packaged programs. The accuracy of structure determined by exploratory factor analysis was confirmed by confirmatory factor analysis. Results: The scale comprises 6 subdimensions, including psychological, self-efficacy, perceived barriers, acceptance, perceived benefits, and spirituality, with a total of 37 items. The Kaiser-Meyer-Olkin (KMO) value of the developed Belief Scale for Complementary and Alternative Medicine was calculated as 0.925. The Bartlett’s test result was significant (p = 0.000), indicating high correlations among variables. Conclusion: The developed Belief Scale for Complementary and Alternative Medicine was found to be a reliable and valid scale with psychometric properties.
Sleeve gastrectomy versus Roux-en-Y-gastric bypass in patients with body mass index over 50 kg/m2: international multicentre cohort
(Oxford University Press, 2026) Kollmann, Lars; Rosenblum, Ilan; Poljo, Adisa; Probst, Pascal; Muller, Markus K.; Kalinowski, Piotr; Dalkılıç, Muhammed S.; Şişik, Abdullah
Background Patients with initial body mass index > 50 kg/m(2) are vastly under-represented in randomized clinical trials demonstrating similar weight loss and diabetes remission rates after sleeve gastrectomy and Roux-en-Y gastric bypass. Methods Propensity score matching 1 : 1 was used to compare outcomes regarding weight loss and diabetes control after sleeve gastrectomy and Roux-en-Y gastric bypass in patients with body mass index > 50 kg/m(2) between 2012 and 2022 in a cohort from 13 centres in six European countries. The primary endpoint was percentage total bodyweight loss; secondary endpoints were diabetes remission rate and rate of persistent body mass index > 40 kg/m(2). Results In total, 3976 of 8160 patients were matched and included in the analysis (1988 in each group). Median age at baseline was 40.0 (range 16-76) years in the sleeve gastrectomy group and 39.5 (15-71) years in the Roux-en-Y gastric bypass group. Median body mass index at baseline was 56.2 (range 50.0-100.0) and 54.3 (50.0-83.9) kg/m(2), respectively (P < 0.001). The follow-up rate was 70.5% at 1 year and 24.4% at 5 years. Percentage total bodyweight loss at 1 and 5 years after sleeve gastrectomy was 30.2 (2.2-63.7) and 25.4 (-4.8 to 56.0)%, respectively, versus 31.2 (7.4-54.5) and 28.2 (-6.6 to 62.9)% in the Roux-en-Y gastric bypass group (P < 0.001 between groups in both time points). The prevalence of persistent body mass index > 40 kg/m(2) after 1 and 5 years was 42.7 and 57.6%, respectively, after sleeve gastrectomy versus 24.5 and 39.2% after Roux-en-Y gastric bypass (P < 0.001 between groups in both time points). A 5-year follow-up, the prevalence of a pathological haemoglobin A1c level (> 6.5%) was 12.9% after sleeve gastrectomy and 11.6% after Roux-en-Y gastric bypass (P = 0.323). Conclusion This study suggests that Roux-en-Y gastric bypass results in greater weight loss than sleeve gastrectomy in patients with body mass index > 50 kg/m(2), whereas improvements in diabetes appear comparable between procedures.
Thermal deformation in non-planar large-scale additive manufacturing of ABS: experimental and finite element analysis
(MDPI, 2026) Aladağ, Mehmet; Tek, Engin; Akeloğlu, Mehmet Ali; Dubicki, Adrian; Zglobicka, Izabela; Eyercioğlu, Ömer; Kurzydlowski, Krzysztof J.
In this study, thermal deformation in non-planar, large-scale additive manufacturing (LSAM) was experimentally and numerically investigated. A B & eacute;zier-based non-planar build surface was fabricated by CNC machining, and a single layer of ABS was deposited using a hybrid LSAM system. Toolpaths with raster angles of 0 degrees and 45 degrees were generated for surface-conformal printing. Infrared thermography was employed to monitor the thermal history during deposition. A three-dimensional finite element model was developed to simulate transient heat transfer and thermally induced deformation. Experimental deformation was quantified by 3D scanning and compared with simulation results. The results show that the slope geometry strongly influences deformation direction: negative slopes promote contraction, whereas positive slopes lead to upward deflection. Maintaining the material temperature above the glass transition temperature significantly reduces skew deformation. The finite element method predictions demonstrate strong agreement with experimental measurements, with normalized root mean square errors (NRMSEs) of approximately 11% for thermal deformation and 10% for temperature history. The proposed framework enables prediction and mitigation of thermal warping in non-planar polymer additive manufacturing.
Intellectual property and regional growth in Türkiye: a spatial analysis of education, trade, and population dynamics
(Istanbul University Press, 2026) Şaşmaz, Abdullah Bahadır
This research investigates the determinants of regional economic growth in T & uuml;rkiye between 2008 and 2023, focusing on GDP persistence, population density, trade openness, education, and intellectual property rights (IPRs), particu larly patent, utility model, trademark, and industrial design registrations. Spatial panel data analysis with spatial autoregressive model (SAR), spatial durbin model (SDM), and spatial error model (SEM) is applied to 81 cities at the NUTSIIIlevel, providing a comprehensive perspective on regional dynamics. The findings confirm statistically significant spatial autocorrelation, indicating that neighboring cities influence each other's economic performance. GDP persistence and population density positively affect growth, while tertiary education negatively correlates with GDP. Trade openness is not statistically significant. Design and utility model registrations contribute positively to growth, whereas patents and trademarks show negative effects, highlighting the need for policy alignment with regional economic structures.
Sustainable cross-cultural service management: cultural intelligence as a mediating mechanism between cultural values and influence tactics in international civil aviation
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Ergün, Ercan; Sever Elüstün, Tunay; Balcıoğlu, Yavuz Selim
Sustainable service excellence in globalized industries requires organizations to develop workforce capabilities that support long-term relationship-building, cultural respect, and effective cross-cultural communication. This study examines how cultural intelligence functions as a mechanism for sustainable cross-cultural workforce development by investigating relationships among individual cultural values, cultural intelligence dimensions, and influence tactics among airline cabin crew members. Integrating Hofstede's cultural dimensions framework, Ang and colleagues' cultural intelligence model, and Yukl's influence tactics taxonomy, we test a comprehensive mediation model using survey data from six hundred and sixty-three cabin crew members employed by international airlines operating in Turkey. The findings reveal that collectivism, long-term orientation, and uncertainty avoidance positively predict cultural intelligence development, creating foundations for sustainable cross-cultural competence. Cultural intelligence dimensions demonstrate differentiated effects on influence tactics, with metacognitive and behavioral cultural intelligence enhancing rational persuasion, behavioral cultural intelligence exclusively predicting relational tactics, and complex competitive mediation patterns for coercive tactics wherein motivational cultural intelligence reduces pressure-based influence while cognitive and behavioral dimensions increase strategic assertiveness. Cultural values directly influence tactics beyond cultural intelligence effects, with uncertainty avoidance most strongly predicting both rational and relational approaches that support relationship sustainability, while masculinity and power distance drive coercive tactics that may undermine long-term service relationships. These findings demonstrate that cultural intelligence functions as a multidimensional mediating mechanism with sometimes opposing effects, challenging assumptions that cross-cultural competencies uniformly produce sustainable outcomes. The research contributes to sustainable human resource management theory by illuminating how cultural socialization influences behavioral outcomes through complex psychological pathways, while offering practical guidance for aviation industry recruitment, training, and performance management systems seeking to build sustainable cross-cultural service capabilities. By revealing that certain cultural intelligence dimensions can enable both relationship-building and strategic coercion, the study highlights the importance of coupling cross-cultural skill development with ethical frameworks and motivational engagement to ensure that enhanced cultural capabilities support rather than undermine sustainable, respectful cross-cultural service relationships.
The effect of emotional freedom technique on maternity blues symptoms and breastfeeding self-efficacy: a randomized controlled trial
(Springer Nature, 2026) Çuvadar, Ayşe; Guksu, Zuhal; Çuvadar Baş, Yeter
Background: Emotional Freedom Technique (EFT) is a complementary method used to reduce psychological distress and enhance self-efficacy. Postpartum women with maternity blues often experience emotional difficulties that may negatively affect breastfeeding. Evaluating the effect of EFT on maternity blues and breastfeeding self-efficacy can contribute to improving postpartum care. Methods: This randomized controlled, parallel-group study with a pre-test–post-test design included 64 breastfeeding women aged 18–39 who had a Maternity Blues Scale score above 100. Data were collected using the Personal Information Form, Maternity Blues Scale, and Breastfeeding Self-Efficacy Scale–Short Form. The intervention group received two sessions of EFT, each lasting approximately 45–60 min, while the control group received routine breastfeeding counseling. Results: In this study, we investigated the effect of EFT on breastfeeding outcomes in women experiencing maternity blues. Following the intervention, EFT significantly reduced maternity blues scores (post-test Z = -6.880, p < 0.001) and increased breastfeeding self-efficacy scores (post-test Z = -6.380, p < 0.001). Specifically, the mean Maternity Blues Scale (MBS) score decreased by 57.5%, corresponding to a large effect size (Cohen’s d = -3.72), while the mean Breastfeeding Self-Efficacy Scale–Short Form (BSES-SF) score increased by 33.7%, also demonstrating a large effect size (Cohen’s d = 2.55). These findings indicate that EFT had a substantial positive impact on reducing postpartum emotional distress and enhancing breastfeeding confidence among mothers. Conclusion: EFT stands out with its easy applicability, effectiveness, low cost, and non-invasive structure. This study demonstrates that EFT can effectively alleviate maternity blues and enhance breastfeeding self-efficacy, highlighting its potential as a practical intervention for postpartum care.
Electrospun PVA/CS/HA/BA nanofiber scaffolds with enhanced mechanical stability and antifungal activity for bone tissue engineering
(Multidisciplinary Digital Publishing Institute (MDPI), 2026) Yavuz, Yağızer; Kartal, İlyas; Cesur, Sümeyye; Kanlı, Zehra; Kaya, Elif; Tinaz, Gülgün; Gündüz, Oğuzhan
In this study, we created multifunctional bone tissue engineering scaffolds that combine prophylactic antifungal action with structural support. We produced PVA/CS/HA/BA nanofiber matrices via a specifically designed electrospinning technique to stop early cross-linking. Through SEM, our examination of fiber shape revealed diameters ranging from 178 +/- 53 nm to 330 +/- 69 nm. We discovered that this variation was closely correlated with the Boric Acid (BA) level. Our EDS and FTIR studies further showed that HA and BA were effectively mixed, with a specific focus on the production of borate-ester linkages inside the network. Mechanical examination revealed that 0.25 wt.% BA maximizes the tensile strength at 9.15 MPa, thereby closely matching HA-reinforced standards, while HA incorporation improved thermal stability. Moreover, in vitro hFOB experiments showed sustained cytocompatibility at 0.25 wt.% BA. While 0.5 wt.% BA showed strong antifungal action against Candida albicans, it sadly harmed cell viability. The 0.25 wt.% BA concentration ultimately offers a better balance between mechanical integrity and antibacterial action, therefore presenting a potential method for scaffold generation for bone regeneration in immunocompromised patients.
