Öğe Türü: Yayın , Luminescence properties of Al4B2O9:M (M= Pb2+ and Bi3+) phosphors for down-shifting applications(Springer Int Pubg Ag, 2026) Pekgözlü, İlhan; Yılmaz, Mükremin; Yılmaz, Mükremin; Mühendislik Mimarlık ve Tasarım Fakültesi, Metalurji ve Malzeme Mühendisliği BölümüAl4B2O9, Al4B2O9:Pb2+, and Al4B2O9:Bi3+ powders with varying activator concentrations were synthesized via a solution-combustion method. The crystal structure of the prepared materials was confirmed by X-ray diffraction (XRD), while Fourier transform infrared (FTIR) spectroscopy confirmed the presence of characteristic B-O and Al-O bonding. The morphology of the materials was examined using scanning electron microscopy (SEM) and EDS mapping, revealing a dense structure of micron-sized particles with smooth cleavage planes and uniform elemental distributions. Photoluminescence measurements of Al4B2O9:Pb2+ and Al4B2O9:Bi3+ phosphors showed strong ultraviolet excitation and emission in the near-UV region, accompanied by large Stokes shifts. Concentration quenching occurred at critical concentrations of 3.0 mol% for Pb2+ and 1.0 mol% for Bi3+. Increasing dopant content induced a systematic red shift in the Pb2+ series, whereas the Bi3+ series displayed a much smaller spectral shift. The distinct emission behaviors of Pb2+ and Bi3+ allowed for concentration-dependent tuning of the optical properties. These findings suggest that Al4B2O9:M (M = Pb2+, Bi3+) phosphors are promising candidates for luminescent down-shifting applications.Öğe Türü: Yayın , Factors Related to Adolescents' Social Media Addiction and Book Reading Habits(Turkish Librarians Assoc, 2026) Durualp, Enver; Güneş, Lügen Ceren; Durualp, Ender; Durualp, Enver; Eğitim Fakültesi, Eğitim Bilimleri BölümüPurpose: This study examines factors associated with middle school students' social media addiction and reading habits. Method: This study utilised descriptive and correlational survey models within a quantitative research framework. The study sample comprised of a total of 387 adolescents (215 female and 172 male) and was selected using convenience sampling methods. Data were collected online using a 'General Information Form,'the 'Social Media Addiction Scale for Adolescents,'and the 'Middle School Book Reading Habit Scale.' The resulting data were analysed using descriptive statistics, such as frequency, percentage, mean, skewness, and kurtosis, and oneway analysis of variance, LSD, and Tamhane tests. Findings: The research findings indicate that adolescents' social media addiction and book reading habits differ significantly based on daily social media usage time, the type of social media used, the purpose of social media usage, the number of social media accounts owned, and academic achievement levels. Adolescents who spent more time on social media daily, preferred TikTok, used social media for socialising and sharing, had multiple social media accounts, and had lower academic achievement demonstrated higher social media addiction scores. In contrast, adolescents who spent 1-2 hours per day on social media, utilised platforms other than TikTok, used social media to follow current events, maintained only one social media account, and demonstrated higher academic success exhibited higher book reading habit scores. Implications: A moderate, negative, and significant relationship was found between social media addiction and book reading habits. This result indicates that adolescents' intense and continuous use of social media platforms may negatively affect traditional book-reading behaviour. Originality: This study contributes to the limited literature by systematically addressing the relationship between social media addiction and book reading habits. The study reveals the effect of social media use on book-reading habits and possesses scientific originality regarding its potential to inform educational policies, curriculum development processes, and protective intervention strategies.Öğe Türü: Yayın , Development of a fire-resistant phase change material for energy efficiency in residential buildings(Springer Science and Business Media B.V., 2026) Helvalı, Mahmut; İlkin, Nisanur; Grzeskowiak, Wojciech; Can, Ahmet; Can, Ahmet; Orman Fakültesi, Orman Endüstri Mühendisliği BölümüThis study investigated the effects of capric acid (CA) and boric acid (BA)-based phase change materials (PCMs), developed to improve energy efficiency in residential buildings, on the fire behavior of wood materials. The microstructure, chemical composition, thermal behavior, and thermal stability of the composite were characterized using Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Mini Fire Tube (MFT), and mass loss calorimetry (MLC) tests. At this loading, the latent heat values were 63.47 J g−1 during melting at 30.7 °C and 67.43 J g−1 during freezing at 25.9 °C for (CA+BA)w. The maximum exhaust gas temperature was measured as 534.9 °C in the (CA+BA)w variant and 545.6 °C in the CA variant. MLC analyses showed that the highest peak heat release rate (pHRR) was 350.0 kW m−2 in CAw-containing samples, while this value decreased to 141.7 kW m−2 in BAw-containing samples.Öğe Türü: Yayın , Breastfeeding Experiences, Challenges, and Barriers Among Mothers During Hot Weather in Türkiye: A Qualitative Study(Springer/Plenum Publishers, 2026) Dinç, Fatma; Kurt, Aylin; San, Emine Güneş; Şan, Emine Güneş; Kurt, Aylin; Dinç, Fatma; Sağlık Bilimleri Fakültesi, Hemşirelik BölümüObjectives This study aimed to explore mothers' breastfeeding experiences, challenges, and barriers during hot weather in T & uuml;rkiye.Methods A qualitative exploratory approach was used in this study. Between August and October 2024, in-depth individual interviews were conducted with mothers who applied to the breastfeeding outpatient clinic at the obstetrics and gynecology hospital in a city in the Western Black Sea region of T & uuml;rkiye. The sample included 18 mothers who agreed to participate in the study. Thematic analysis was used to analyze the data.Results Five main themes emerged from the interviews: (1) physical and emotional barriers to breastfeeding, (2) social and privacy barriers to breastfeeding, (3) psychological challenges and support needs, (4) environmental and climatic barriers, and (5) strategies for overcoming breastfeeding barriers. The findings indicate that hot weather conditions are associated with various challenges for mothers, such as physical discomfort, emotional strain, social isolation, and sleep problems. Mothers expressed the need for adequate fluid consumption, appropriate environmental adjustments, and social support; they also highlighted the need for support to cope with the stress and psychological challenges they experience during hot weather conditions.Conclusion for Practice This study shows that hot weather poses significant physical and emotional challenges to the breastfeeding process. In order for mothers to breastfeed comfortably in hot weather conditions, it is important to provide cool environments, increase fluid consumption, establish air-conditioned breastfeeding points in public spaces, expand social support groups, and provide guidance and psychological support from health professionals.Öğe Türü: Yayın , Barrier-Free Religious Education Technology: Development of A Mobile App for People with Hearing Impairments and Evaluation of User Feedback(DINBILIMLERI AKAD ARASTIRMA MERKEZI, 2026) Afacan, Kevser; Çoştu, Kamil; Çoştu, Kamil; İlahiyat Fakültesi, Felsefe ve Din Bilimleri BölümüThis study aims to design a digital mobile application for the Qur'an learning processes of individuals with hearing impairments and to analyze its impacts. Using the Design and Development Research (DDR) method, the study developed a unique mobile application that includes sign language videos, telegraphic writing support, visual animations, and structured lesson content ranging from simple to complex. During the development process of the application, Green Screen and Chroma Key techniques were employed to design an interface appropriate to the culture of individuals with hearing impairments and their visual learning styles. To obtain findings regarding the user experience (UX) of the developed mobile application, semi-structured interviews were conducted at three Qur'an courses serving individuals with hearing impairments, following official permission from the Ankara Provincial Directorate of Religious Affairs. The majority of the participants were women (7 women, 5 men). The fact that most of those attending the need-oriented Qur'an courses providing services within the Presidency of Religious Affairs are women makes this situation meaningful. Data concerning the user experience of individuals with hearing impairments in relation to the teaching of the Holy Qur'an were analyzed using MAXQDA software. In the qualitative data analysis process, 61 codes were organized within 5 main themes. The findings clearly indicate that the mobile application developed for individuals with hearing impairments provides equal opportunities by eliminating spatial, temporal, and linguistic barriers inherent in traditional education. Participants reported that the application enabled them to learn at their own pace and strengthened their sense of belonging to a "special target group," resulting in an increase in spiritual belonging and self-confidence. In addition, multimedia materials were found to enhance retention and contribute to participants' ability to independently perform basic religious practices. Although participants stated that the mobile application provided easy access to a substantial amount of new information, they also emphasized the continuing need for mentors. In conclusion, technology designed for the cognitive and sensory needs of individuals with hearing impairments offers an inclusive and sustainable model for Qur'an and religious education. It has been understood that the application, which ensures equal opportunities in education and facilitates access to education, is pedagogically functional and provides an effective learning experience. This situation demonstrates the importance of coordinated efforts across diffe-rent scientific disciplines such as science, health, religion, and others, aimed at addressing the needs of individuals with hearing impairments. It has been concluded that it is important to increase the number of similar programs aimed at the religious education and instruction of individuals with hearing impairments and to provide greater information about educational technology to religious culture and ethics teachers working in the field. In addition, through technology literacy training prepared for individuals with hearing impairments, it is possible to enable them to use existing applications effectively.
