(Springer Science and Business Media Deutschland GmbH, 2026) Kanbay, Yalçın; Akkurt Yalçıntürk, Aydan; Babaoğlu Gülseven, Elçin; Akçam, Aysun
Aim: Developing a measurement tool to determine digital dementia is an important step toward understanding the prevalence and effects of digital dementia. The present study aimed to develop the “Digital Dementia Scale Adult Form” to determine digital dementia in individuals aged 18 and over by examining the concept of digital dementia. Methods: The form which consisted of 22 statements with proven validity in terms of language and psychometrics was applied to 615 individuals. Exploratory and confirmatory factor analysis was used to determine the construct validity, and a 27% lower-upper group comparison was made to determine the internal validity Results: The “Digital Dementia Scale Adult Form” consisted of 3 subdimensions and 15 items and could explain 65.7% of the total variance as a 5-point Likert-type scale (Never: “0”, Rarely: “1”, Sometimes: “2”, Frequently: “3”, and Always: “4”). The total score on the scale varies between 0-60, and as the score increases, the level of digital dementia also increases. The Cronbach α Reliability Coefficient of the scale was calculated as.92, indicating high reliability. Conclusion: The “Digital Dementia Scale Adult Form” is valid in terms of scope and content and has high reliability.

(Taylor and Francis Ltd., 2026) Gültekin, Ergün; Doğan, Hacer; Atalay, Abdurrahman; Canbolat Gültekin, Deniz; Özkan, Ahmet İsmail
Aims: To synthesize novel 1,2,4-triazole-5-thione-quinoline Schiff base hybrids and evaluate their urease inhibitory, antimicrobial, antioxidant, and computational properties. Materials and methods: Two series of compounds, 7(a–d) and 8(a–d), were synthesized and structurally characterized by Fourier Transform-Infrared (FT-IR), 1 H/13C Nuclear Magnetic Resonance (NMR), mass spectrometry, and elemental analysis. Urease inhibition was determined spectrophotometrically. Antimicrobial activity was assessed by disc diffusion and broth microdilution methods. Antioxidant activity was evaluated using ferric-reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. Density functional theory (DFT) and molecular docking studies were also performed. Results and conclusions: Compounds 7c and 8c showed the strongest urease inhibitory activity, each with an IC50 value of 1.37 mM. 8c displayed the best docking score (−7.6 kcal/mol), while 7c showed favorable binding affinity (−6.9 kcal/mol). Antimicrobial screening revealed selective activity mainly against Gram-positive bacteria and fungi, while Gram-negative bacteria were generally resistant. Compound 7d displayed the broadest antimicrobial profile, with minimum inhibition concentration (MIC) values of 39.06 µg/mL against Staphylococcus aureus and 19.53 µg/mL against Streptococcus pyogenes. In antioxidant assays, 7d and 8d showed the highest FRAP values, whereas 8c and 8a showed the strongest DPPH radical-scavenging activity. DFT results supported the observed structure–activity relationships.
Effect of sweetgum (Liquidambar orientalis) leaf extract on technological properties of pine (Pinus brutia)
(North Carolina State University, 2026) Ulusoy, Hatice; Peker, Hüseyin; Yılmaz, Sultan Şeyma
The main objective of this research was to determine the retention properties of extracts obtained from the leaves of Liquidambar orientalis Mill., (belonging to the class of medicinal aromatic plants) to organic (ecological) wood structures, thereby creating an ecological wood preservative that could be preferred in a wide variety of applications. Wood samples were taken from red pine trees in the Köyceğiz Agla region. Then, 1%, 3%, and 5% solutions of the extract were prepared. Vacuum method was used as the impregnation method. After impregnation and conditioning, the experimental and control samples were tested for mechanical properties such as bending strength, modulus of elasticity, compressive strength, and dynamic bending strength, while physical properties such as air-dry and specific gravity tests were conducted. The highest retention value was found at a 5% concentration (1.13%), the highest air-dry specific gravity value at a 1% concentration (0.56 g/cm³), and the highest air-dry specific gravity at a 1% concentration (0.53 g/cm³). Among the mechanical properties, the highest bending strength value was determined at a 5% concentration (1.13%), the highest modulus of elasticity at 1% (9145 N/mm²), and the dynamic bending strength at a 3% concentration (0.27 kgm/cm²).
Soil quality improvement potential of wood ash and peat moss in copper mine waste rock dumpsite: A case study in Artvin, Turkey
(North Carolina State University, 2026) Küçük, Mehmet; Yener, İsmet
With the ultimate goal of facilitating in situ phytostabilization and ecological restoration of mining sites rather than agricultural use, the present study aimed to investigate the effects of wood ash and peat on the physicochemical properties and nitrogen mineralization in copper-mine-affected soils. To this end, soil samples were collected from copper mine waste rock dumpsites and amended with wood ash, peat moss, and their mixture, at various rates. Various soil properties were determined at two incubation periods (day 0 and day 63). To reveal differences among soil amendments, a post hoc test with the Bonferroni correction, principal component analysis (PCA), PCA biplot, and Log2 fold change heat map analyses were applied. As a result, all soil properties, except the ammonium level at day 63, differed significantly for at least one type of amendment (P < 0.05). The overall effects of the treatments on physicochemical soil properties and nitrogen mineralization, as determined by PCA, indicated that wood ash had the greatest effect on pH and EC. In contrast, peat moss dominated nitrogen dynamics, as reflected by organic carbon and organic matter. The results of this study could be used to remediate mine-polluted, acidified, and nutrient-depleted soils.
Unpacking the emotional intelligence and professional competence nexus: the mediating role of vocational interest among prospective teachers
(Routledge, 2026) Aydın Güngör, Tuba; Çakır, Çiğdem; Öztürk, Necati
Teacher professional competence is central to quality education, and its importance grows as teaching becomes more complex and dynamic. Given the increasing emphasis on both cognitive and non-cognitive skills in teacher education, this study adopts a relational survey model to examine how emotional intelligence contributes to professional competence, and whether vocational interest serves as a motivational bridge between the two. Findings from prospective teachers revealed that emotional intelligence was significantly associated with both vocational interest and professional competence, and that vocational interest was significantly and positively associated with professional competence. Crucially, vocational interest partially mediated the relationship between emotional intelligence and professional competence, as confirmed by bootstrap analysis. These findings suggest that fostering emotional intelligence in teacher candidates supports interpersonal effectiveness and well-being while enhancing intrinsic motivation towards the profession, thereby strengthening professional competence. The study advocates a more holistic approach in teacher development programmes, integrating emotional and motivational dimensions.
