The increasing integration of artificial intelligence (AI) in education highlights the need for teacher preparation programs to support pre-service teachers in developing pedagogically grounded and ethically responsible AI competencies. This study designed and preliminarily examined an Experiential Design Learning model within a Digital Learning Ecosystem (EDL–DLE) to support the development of AI competencies and instructional innovation in pre-service science teacher education. A four-phase research and development framework was employed, including conceptual synthesis, model design and expert validation, implementation, and evaluation. Participants were 19 second-year pre-service science teachers from a university in Bangkok. Research instruments included a 40-item AI competency assessment and an instructional innovation evaluation rubric. Paired-sample t-test results indicated statistically significant pre–post difference across all AI competency dimensions, with large effect sizes (Cohen’s d = 0.82–1.59), reflecting notable within-group changes observed within the EDL–DLE learning context. The instructional innovation lesson plans were evaluated as generally strong across multiple dimensions, particularly in learner-centered pedagogy, creativity, and collaboration, while relatively lower performance was observed in appropriate AI technology selection and ethical use. Overall, the findings provide preliminary evidence supporting the feasibility of the EDL–DLE model as an exploratory instructional approach for fostering foundational AI-related pedagogical competencies in pre-service science teacher education.
This paper explores how local football supporters in Thailand negotiate identity, loyalty, and belonging in a globalized sporting landscape. Focusing on Buriram United, a club rebranded under the leadership of political figure Newin Chidchob, it examines how fandom intersects with political symbolism, regional development, and cultural participation. Drawing on interviews, ethnographic observation, and media analysis, the research finds that supporters co-construct hybrid identities rooted in place-based pride, emotional governance, and symbolic resistance to globalized fandom. Stadium rituals, regional branding, and political patronage emerge as key mechanisms sustaining allegiances. The study argues that football in Thailand operates as both a cultural form and a political instrument, advancing localized forms of legitimacy and identity-making. By situating a non-Western case within broader debates on globalization and fandom, this research contributes original insights into how ordinary supporters experience football not just as entertainment, but as a vehicle for civic pride and socio-political change.
The preparation and characterization of glasses with BaO-Gd2O3-P2O5-CeF3 system were proceeded in this work for scintillator material. Glass density tends to decrease while the molar volume increases with CeF3 addition. Glasses strongly absorb photons in UV region with redshift of absorption edge but it has high transmittance for visible light. The optimum CeF3 concentration is 0.50 mol% which Ce3+ in glass exhibit the strong photoluminescence around 332-338 nm under direct Ce3+ excitation and Gd3+- Ce3+ energy transfer. The photoluminescence decay time of Ce3+ tends to increase by adding CeF3 that value of 0.50 mol% doped glass is short around 27 ns. X-rays induced luminescence spectra exhibit the similar pattern to that of photoluminescence spectra with Gd3+ -> Ce3+ energy transfer. The integral scintillation efficiency of 0.50 mol% doped glass is around 42 % compared to BGO crystal. This glass was operated in the practical X-ray imaging which created the quality image by a spatial resolution of 37.6 LP/mm. The developed glass owns high luminescence potential for using as a scintillator in X-ray detector and imaging applications.
The existing methodologies for detecting foodborne pathogens often involve laborious and time-consuming procedures, underscoring the need for rapid and effective detection techniques. Herein, we present a super-hydrophobic magneto-flow system integrated with an electrochemical aptasensor designed for simple, sensitive, yet controlled detection of Salmonella enterica serovar Typhimurium (Salmonella) in food samples. A super-hydrophobic surface created through a chemical gold reduction method on a polydimethylsiloxane substrate enabled a distinct fluid orientation within a microfluidic device that prevents merging, thereby reducing contamination and enhancing detection rates. A laminate magneto-driven microfluidic device was fabricated using laser cutting and assembled to establish channel barriers that allow for precise control of magnetic flow direction using magnetic force, rather than relying on external pumps or absorbent pads. Aptamers specifically targeting Salmonella were conjugated to magnetic beads and aligned on the superhydrophobic surface with a custom-designed pattern to facilitate one-time spotting of the requisite reagents. Using a single introduced platform, the entire operation, including Salmonella-aptamer capturing, washing, and electrochemical measurement, can be performed sequentially, akin to a move-pause station. The aptasensing system operated in a label-free format, demonstrated the capability to detect Salmonella in food samples, achieving high sensitivity successfully (limit of detection = 10.01 CFU/mL), selectivity, a rapid response time (30 min), and a broad linearity range (10-105 CFU/mL), verified by standard approaches. This device embodies a cutting-edge immunosensing platform that facilitates precise operational control and features simple fabrication processes, rendering it a viable alternative suitable for complex multi-step procedures.
A series of Dy3+/Gd3+ co-doped Ba-Na-N glasses were synthesized via the melt-quenching method and investigated for their photoluminescence (PL) and radioluminescence (RL) properties. Under 387 nm excitation (Dy3+ ions), the sample containing 1.0 mol% Dy2O3 exhibited the strongest PL intensity, achieved a photoluminescence quantum yield (PLQY) of 7.59 %. Upon 275 nm excitation (Gd3+ ions), efficient energy transfer from Gd3+ to Dy3+ was observed, with the strongest PL intensity obtained in the 0.5 mol% Dy2O3 sample. Chromaticity coordinates of all samples were located near (x = 0.37, y = 0.42), confirming their white-light emission capability. For RL measurements under X-ray excitation, the 0.50 mol% Dy2O3 glass sample reached an integral scintillation efficiency of 14.84 % relative to a commercial BGO standard. These results highlight the potential of the developed glasses in this work for use in white light-emitting devices and cost-effective X-ray scintillators.
