This study aimed to develop a formula and production process for snacks made from germinated brown rice flour and banana flour using the extrusion process. The results indicated that both germinated brown rice flour and banana flour could be effectively used as the main raw materials for snack production via extrusion. The proportion of flour in the formula and production conditions, such as moisture content of the raw materials, barrel temperature, and screw speed, significantly influenced the nutritional value, bioactive compound levels, and antioxidant activity of the final products.

The species Enterococcus lactis is closely related to E. faecium and is known for its beneficial and probiotic effects. In this study, strain RRS4 was isolated from Raphanus sativus Linn. and identified based on both phenotypic and genotypic characteristics. Strain RRS4 exhibited cell viability in environments with 2-8% NaCl, pH ranging from 4 to 9, and temperatures between 4°C and 45°C. Through comprehensive genomic analysis, strain RRS4 was confirmed to be E. lactis. E. lactis RRS4 demonstrated inhibitory effects against Vancomycin-resistant E. faecalis JCM 5803. Safety assessments via in silico methods, including KEGG annotation, indicated the absence of virulent and undesirable genes in E. lactis RRS4. VirulenceFinder analysis aligned virulence-related genes with those from three strains of E. lactis and four strains of E. faecium. While antibiotic resistance genes were found to be conserved, they did not correlate with key pathogenicity traits. Furthermore, safety evaluations highlighted that E. lactis RRS4 is generally safe, despite the presence of genes associated with antibiotic resistance. Lastly, we propose guidelines for assessing the safety of microbial strains using whole-genome analysis. These findings represent advancements in probiotic research.

This research focuses on the design of a Metaverse Prototype Thai Film Archive (Public Organization) to study immersive experiences. The aims were to: 1) examine design concepts and technologies for digital immersion, 2) create and showcase these designs in the Metaverse cinema, and 3) evaluate the results and formulate knowledge for virtual exhibition design using qualitative research methods, including prototype testing with participant interviews to assess satisfaction. The design principles consisted of architectural, exhibition, and user experience concepts, leading to a virtual world creation process involving 3D structural modeling, interactive functionalities, and exhibition layout before prototype testing. The evaluation included tests by ten participants and group discussions on overall experience, cinema content value, Metaverse design, and educational enhancement in museums. The design evaluation indicated a 70% positive overall experience, with half of the users finding stable usability. However, significant viewing barriers were identified, with a high need for operational instructions and navigational aids. Content understanding and Metaverse interaction were perceived positively, and the educational aspect was highly valued. The study concludes that while the overall experience was good, technology limitations (as of 2023) and interaction challenges require ongoing refinement to improve stability and usability, although the educational value was affirmed as strong.

Induction Heating Machine (IHM) is a crucial device in the jewelry industry, utilizing electromagnetic fields to generate heat and join precious metals. This research focuses on developing a Dual Coil Induction Heating Machine (Dual Coil IHM) to enhance production efficiency and reduce costs in jewelry factories using Electromagnetic Analysis (EMA) through Ansys Maxwell software. The research process began with testing a single-coil IHM under real operating conditions and using EMA to analyze the generated magnetic flux density (B). Subsequently, dual-coil configurations in Parallel and Series arrangements were designed and compared. The experimental results revealed that the series dual coil produced a higher magnetic flux and allowed for optimizing current (I), frequency (f), number of coil turns (N), and coil spacing (d) for better manufacturing performance. The findings indicate that the series dual-coil IHM can double production capacity compared to the conventional single-coil model. Furthermore, EMA technology minimizes physical testing, reduces errors, and enhances precision in designing industrial machinery for the jewelry manufacturing sector.
