Article Citation - WoS: 1Citation - Scopus: 2Cochleogram-Based Speech Emotion Recognition With the Cascade of Asymmetric Resonators With Fast-Acting Compression Using Time-Distributed Convolutional Long Short-Term Memory and Support Vector Machines(Mdpi, 2025) Parlak, CevahirFeature extraction is a crucial stage in speech emotion recognition applications, and filter banks with their related statistical functions are widely used for this purpose. Although Mel filters and MFCCs achieve outstanding results, they do not perfectly model the structure of the human ear, as they use a simplified mechanism to simulate the functioning of human cochlear structures. The Mel filters system is not a perfect representation of human hearing, but merely an engineering shortcut to suppress the pitch and low-frequency components, which have little use in traditional speech recognition applications. However, speech emotion recognition classification is heavily related to pitch and low-frequency component features. The newly tailored CARFAC 24 model is a sophisticated system for analyzing human speech and is designed to best simulate the functionalities of the human cochlea. In this study, we use the CARFAC 24 system for speech emotion recognition and compare it with state-of-the-art systems using speaker-independent studies conducted with Time-Distributed Convolutional LSTM networks and Support Vector Machines, with the use of the ASED and the NEMO emotional speech dataset. The results demonstrate that CARFAC 24 is a valuable alternative to Mel and MFCC features in speech emotion recognition applications.Article Citation - WoS: 3Citation - Scopus: 3Coach Candidates' and Coaches' Nutrition Knowledge Affects Dietary Recommendations Indirectly: Mediator Effects of Self-Efficacy(Mdpi, 2025) Altinok, Oyku; Bas, MuratBackground/Objectives: The nutritional knowledge and behavior of athletes are considerably influenced by the dietary recommendations of their coaches, which, in turn, affect their health and performance. In the context of social cognitive theory, this study examines the impact of general and sports nutrition knowledge (GeSNK), nutrition self-efficacy (NSE), and nutrition counseling self-efficacy (NCSE) on the dietary recommendations (DRs) provided by coach candidates and coaches (CC&Cs). Additionally, it explores variations in GeSNK, NSE, and NCSE among CC&Cs based on their sports positions, genders, and types of sports. Methods: This study included 70 coach candidates and 102 coaches, with data collected via validated scales for GeSNK, NSE, and NCSE. Using the PROCESS macro, the serial multiple mediator model was applied, and group comparisons were conducted via the Mann-Whitney U test. Results: The results revealed that 36% of participants achieved adequate GeSNK scores, but only 6.4% abstained from providing DRs. Participants engaged in individual sports exhibited higher NSE and NCSE scores than those involved in team sports. Additionally, 22.7% of CC&Cs identified their former coaches as a primary source of nutrition information. The study findings revealed that GeSNK, NSE, and NCSE significantly influenced DRs, collectively accounting for 23% of the variance in DRs. The direct effect of NCSE on DRs was statistically significant, whereas the direct effects of GeSNK and NSE were not significant. GeSNK and NSE jointly explained only 41% of the variance in NCSE, suggesting that additional factors influencing NCSE and DRs remain unexplored. Conclusions: To address the issue of inadequate dietary recommendations stemming from insufficient information, it is crucial to identify and understand these additional factors affecting NCSE and DRs. Diversifying nutrition education programs to enhance the nutrition knowledge of CC&Cs is essential. Furthermore, fostering collaboration between CC&Cs and nutritionists can ensure that athletes receive accurate and comprehensive nutritional guidance.Article Citation - WoS: 3Citation - Scopus: 5Systematic Review of Clinical Outcome Parameters of Conservative Treatment of Adolescent Idiopathic Scoliosis Patients(Mdpi, 2025) Colak, Tugba Kuru; Durmus, Betul Beyza; Saatci, Ece Zeynep; Caglar, Engin; Akcay, Burcin; Maeso, Santiago Lasa; Kuru Çolak, TuğbaBackground: The purpose of this systematic review was to investigate the clinical outcome measures, either in separation or in conjunction with the Cobb angle, that were employed in randomized controlled trials to evaluate posture and spinal deformity. Methods: The PubMed, PEDro, OVID, and Scopus electronic databases were used to search for published articles from January 2004 to May 2024. All the searches included English language studies. Keywords were determined as "scoliosis, exercise, physical activity, brace, bracing, conservative treatment, rehabilitation, physiotherapy and physical therapy". Results: The most commonly used clinical evaluation parameters other than the Cobb angle in the studies were the ATR and surface topography measurements. The most commonly used assessment methods were POTSI asymmetry assessment performed with measurements made on photographs, the WRVAS, a deformity perception assessment evaluated with different photographs, and the SRS-22 scale, a disease-specific quality of life assessment. Conclusions: New developments in the treatment of scoliosis have brought about alternative measurement techniques that offer a more comprehensive view of patient outcomes. As a result of the review of the literature, it has emerged that radiation-free, valid, and reliable multidimensional evaluations should be performed in follow-up and treatment efficacy evaluations after initial diagnosis in adolescent idiopathic scoliosis.Review Citation - WoS: 3Citation - Scopus: 5Seroprevalence of Torch Viral Agents in Pregnant Women in Turkey: Systematic Review and Meta-Analysis(Mdpi, 2025) Kilbas, Elmas Pinar Kahraman; Ciftci, Ihsan Hakki; Kilbas, Imdat; Toptan, Hande; Kahraman Kilbas, Elmas PinarRubella Virus, Cytomegalovirus (CMV), Herpes Simplex Virus-2 (HSV-2), Hepatitis B (HBV) and Hepatitis C virus (HCV) can cause serious fetal disease. The seropositivity rates of these agents vary among countries and geographic regions. This study aimed to analyze the prevalence rates and diagnostic methods used in studies investigating the seroprevalence of viral pathogens in the TORCH group among pregnant women in Turkey between 2005 and 2024. A systematic search was conducted using electronic databases between January 2005 and January 2024. A total of 60 studies meeting the inclusion criteria were included. Data quality control was assessed using the Joanna Briggs Institute guideline prevalence studies checklist. Heterogeneity was measured using the I-squared (I-2) statistic in the Comprehensive Meta Analysis (CMA) program. The average seropositivity rates for Rubella, CMV, HSV-2, HBV and HCV in Turkey were determined as 91.18%, 94.81%, 35.52%, 1.66% and 0.25%, respectively. When the diagnostic methods were examined, it was determined that ELISA and ECLIA methods were used most frequently. The seropositivity of the agents did not show statistically significant differences according to the year periods, geographical regions and age of the patients (p > 0.05). The highest prevalence rates of Rubella and HSV-2 in pregnant women were reported in the Mediterranean region, the highest prevalence rates of CMV and HCV in the Southeastern Anatolia region and the highest seroprevalence of Anti HBs in the Marmara region. The results of this study support the necessity of increasing public awareness in the control of fetal infection caused by TORCH viral agents, prenatal screening, vaccination for Rubella and HBV and compliance with hygiene conditions for agents such as CMV, HSV-2 and HCV. The results of this study highlight the need to increase public awareness on prenatal screening for the control of fetal infection caused by all TORCH viral agents, vaccination for Rubella and HBV and compliance with hygiene conditions for agents such as CMV, HSV-2 and HCV.Article Citation - WoS: 3Citation - Scopus: 2Hep® (homeostasis-Enrichment Approach Changes Sensory-Motor Development Trajectory and Improves Parental Goals: a Single Subject Study of an Infant With Hemiparetic Cerebral Palsy and Twin Anemia Polycythemia Sequence (taps)(Mdpi, 2024) Balikci, Aymen; May-Benson, Teresa A.; Sirma, Gamze Cagla; Ilbay, GulBackground: Early intervention (EI) for infants identified as being at high risk for cerebral palsy (CP), or who have been diagnosed with it, is critical for promotion of postnatal brain organization. The aim of this study was to explore the effectiveness of the Homeostasis-Enrichment-Plasticity (HEP) Approach, which is a contemporary EI model that applies the key principles of enriched environment paradigms and neuronal plasticity from experimental animal studies to ecological theories of human development on the motor development, sensory functions, and parental goals of an infant with twin anemia polycythemia sequence (TAPS) and CP. Methods: An AB phase with follow-up single case study design which consisted of multiple baseline assessments with the Peabody Developmental Motor Scales-2 (PDMS-2) and the Test of Sensory Functions in Infants (TSFI) was used. Non-overlapping confidence intervals analysis was used for pre-post PDMS-2 scores. The measurement of progress toward goals and objectives was conducted using the Goal Attainment Scale (GAS). The HEP Approach intervention consisted of 12 one-hour sessions implemented over a period of 3 months, where a physical therapist provided weekly clinic-based parental coaching. Results: Results found a stable baseline during Phase A and improvement in response to the HEP Approach intervention during Phase B in both the PDMS-2 and TSFI according to 2SD Band analysis. The confidence intervals for the PDMS-2 scores also indicated a significant improvement after HEP intervention. The scores for both the PDMS-2 and the TSFI were consistent or showed improvement throughout the Follow-Up phase. A GAS t-score of 77.14 indicated that the infant exceeded intervention goal expectations. Conclusions: Although our findings suggest that the HEP Approach intervention has promise in enhancing sensory functions, motor skill outcomes, and parental goals in an infant with TAPS and CP, further research is required to validate and apply these results more broadly.Article Citation - WoS: 11Citation - Scopus: 23Improving Yolo Detection Performance of Autonomous Vehicles in Adverse Weather Conditions Using Metaheuristic Algorithms(Mdpi, 2024) Ozcan, Ibrahim; Altun, Yusuf; Parlak, CevahirDespite the rapid advances in deep learning (DL) for object detection, existing techniques still face several challenges. In particular, object detection in adverse weather conditions (AWCs) requires complex and computationally costly models to achieve high accuracy rates. Furthermore, the generalization capabilities of these methods struggle to show consistent performance under different conditions. This work focuses on improving object detection using You Only Look Once (YOLO) versions 5, 7, and 9 in AWCs for autonomous vehicles. Although the default values of the hyperparameters are successful for images without AWCs, there is a need to find the optimum values of the hyperparameters in AWCs. Given the many numbers and wide range of hyperparameters, determining them through trial and error is particularly challenging. In this study, the Gray Wolf Optimizer (GWO), Artificial Rabbit Optimizer (ARO), and Chimpanzee Leader Selection Optimization (CLEO) are independently applied to optimize the hyperparameters of YOLOv5, YOLOv7, and YOLOv9. The results show that the preferred method significantly improves the algorithms' performances for object detection. The overall performance of the YOLO models on the object detection for AWC task increased by 6.146%, by 6.277% for YOLOv7 + CLEO, and by 6.764% for YOLOv9 + GWO.Article Citation - WoS: 4Citation - Scopus: 3The Homeostasis-Enrichment (hep®) Approach for Premature Infants With Developmental Risks: a Pre-Post Feasibility Study(Mdpi, 2024) Balikci, Aymen; May-Benson, Teresa A.; Sirma, Gamze Cagla; Kardas, Ayten; Demirbas, Duygu; Balikci, Ayse Firdevs Aracikul; Beaudry-Bellefeuille, Isabelle; Aracikul Balikci, Ayse FirdevsBackground: The environmental enrichment (EE) framework has inspired several early intervention (EI) approaches. This study evaluated the feasibility, safety, caregiver acceptance, and satisfaction of implementing the HEP Approach intervention, a novel EI model based on the EE paradigm. Outcome measures for motor development, individual functional goals, sensory functions, caregiver-provided environmental affordances, and motivation for movement were examined. Methods: A pre-post-study design examined 18 premature infants (<33 weeks six days gestation) with a corrected age of 4-10 months. A 21-item Likert scale survey assessed the feasibility, safety, acceptability, and satisfaction of implementing the HEP Approach intervention. The Peabody Developmental Motor Scales-2, Test of Sensory Functions in Infants, Affordances in the Home Environment for Motor Development, and Infant Movement Motivation Questionnaire were used for outcomes. The goal attainment scale measured progress toward parent goals. The HEP Approach consisted of 12 one-hour sessions implemented over three months. Results: Most participating parents found the HEP Approach intervention feasible, safe, acceptable, and satisfactory. GAS scores demonstrated significant gains with a mean t-score of 67.75 (SD = 2.00). Results found significant improvement (p <= 0.05) in all outcome measures. Conclusions: Results suggest that the HEP Approach intervention is safe, feasible, and acceptable to implement. Outcome measures were meaningful and sensitive in identifying improved motor development, individualized parental goals, sensory functions, caregivers' use of environmental opportunities, and movement motivation in premature at-risk infants. Results suggest further studies on the HEP Approach are feasible, and highlight the potential of this intervention to inspire and guide future research in this field.Article Citation - WoS: 3Citation - Scopus: 3Analyzing Critical Success Factors of Sustainable Knowledge Management: an Interval-Valued Neutrosophic Approach(Mdpi, 2024) Turan, Hakan; Bulak, Muhammet Enis; Buyukselcuk, Elif Caloglu; Çaloğlu Büyükselçuk, ElifKnowledge management (KM) is a structured approach that includes the organized procedures of generating, capturing, arranging, storing, retrieving, distributing, and harnessing an organization's knowledge resources to attain its goals and improve its effectiveness. Encountering uncertainty and managing imprecise information are fundamental aspects of KM that cannot be avoided. In this context, sustainable KM aims to solve these issues and address prioritizing the long-term sustainability and efficiency of knowledge-related processes within an organization. The aim of this study is to structure a sustainable KM concept for organizations and identify the most common critical success factors (CSFs) with a novel analytical approach. In this context, the Interval-Valued Neutrosophic methodology, which is one of the multi-criteria decision methods (MCDMs), was adopted to evaluate and weight the determined CSFs. Four main headings-KM, environmental, economical, and social criteria-are evaluated along with their subfactors. Our findings show that KM is found to be the most important, and environmental factors followed KM. When the results are examined in terms of subfactors, cleaner production is found to be the most significant, with a global weight value of 11.13.Review Citation - WoS: 2Citation - Scopus: 2A Systematic Review and Meta-Analysis of Molecular Characteristics on Colistin Resistance of <i>acinetobacter Baumannii</I>(Mdpi, 2024) Ciftci, Ihsan Hakki; Kilbas, Elmas Pinar Kahraman; Kilbas, Imdat; Kahraman Kilbas, Elmas PinarBackground: This study aimed to determine the molecular epidemiology of colistin-resistant A. baumannii in the last ten years and the frequency of gene regions related to pathogenesis, to compare the methods used to detect genes, and to confirm colistin resistance. Methods: This meta-analysis study was conducted under Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. In the meta-analysis, research articles published in English and Turkish in electronic databases between January 2012 and November 2023 were examined. International Business Machines (IBM) Statistical Package for the Social Sciences (SPSS) Statistics for Macbook (Version 25.0. Armonk, NY, USA) was used for statistical analysis. The Comprehensive Meta-Analysis (CMA) (Version 3.0. Biostat, NJ, USA) program was used for heterogeneity assessment in the articles included in the meta-analysis. Results: After evaluating the studies according to the elimination criteria, 18 original articles were included. Among colistin-resistant strains, blaOXA-51 positivity was 243 (19.61%), blaOXA-23 was 113 (9.12%), blaOXA-58 was 7 (0.56%), blaOXA-143 was 15 (1.21%), and blaOXA-72 was seen in two (0.16%) strains. The positivity rates of pmrA, pmrB, and pmrC were found to be 22 (1.77%), 26 (2.09%), and 6 (0.48%). The mcr-1 rate was found to be 91 (7.34%), the mcr-2 rate was 78 (6.29%), and the mcr-3 rate was 82 (6.61%). Conclusions: The colistin resistance rate in our study was found to be high. However, only some research articles report and/or investigate more than one resistance gene together. Additionally, it may be challenging to explain colistin resistance solely by expressing resistance genes without discussing accompanying components such as efflux pumps, virulence factors, etc.Article Citation - WoS: 7Citation - Scopus: 6The Potential Role of Boron in the Modulation of Gut Microbiota Composition: an in Vivo Pilot Study(Mdpi, 2024) Senturk, Nermin Basak; Kasapoglu, Burcu; Sahin, Eray; Ozcan, Orhan; Ozansoy, Mehmet; Ozansoy, Muzaffer Beyza; Sahin, FikrettinBackground/Objectives: The role of the gut microbiome in the development and progression of many diseases has received increased attention in recent years. Boron, a trace mineral found in dietary sources, has attracted interest due to its unique electron depletion and coordination characteristics in chemistry, as well as its potential role in modulating the gut microbiota. This study investigates the effects of inorganic boron derivatives on the gut microbiota of mice. Methods: For three weeks, boric acid (BA), sodium pentaborate pentahydrate (NaB), and sodium perborate tetrahydrate (SPT) were dissolved (200 mg/kg each) in drinking water and administered to wild-type BALB/c mice. The composition of the gut microbiota was analyzed to determine the impact of these treatments. Results: The administration of BA significantly altered the composition of the gut microbiota, resulting in a rise in advantageous species such as Barnesiella and Alistipes. Additionally, there was a decrease in some taxa associated with inflammation and illness, such as Clostridium XIVb and Bilophila. Notable increases in genera like Treponema and Catellicoccus were observed, suggesting the potential of boron compounds to enrich microbial communities with unique metabolic functions. Conclusions: These findings indicate that boron compounds may have the potential to influence gut microbiota composition positively, offering potential prebiotic effects. Further research with additional analyses is necessary to fully understand the interaction between boron and microbiota and to explore the possibility of their use as prebiotic agents in clinical settings.
