Item type: Item , Item type: Item , โครงการส่งเสริมครูผู้สอนผลิตสื่อออนไลน์คณิตศาสตร์ที่สนับสนุนการเรียนของผู้บกพร่องทางการมองเห็น(กองทุนพัฒนาเทคโนโลยีเพื่อการศึกษา, 2565) ฉวีวรรณ แก้วไทรฮะ; บุญทอง บุญทวี; ลือชัย ทิพรังศรี; พงศ์ระพี แก้วไทรฮะThis project aimed to encourage teachers to produce online mathematics media that supports the learning of the visually impaired to disseminate knowledge in producing mathematics online media that supports learning for the visually impaired in the form of a massive open online course (MOOC). The project implementation is divided into 2 phases: Phase 1 involved online teacher training via Zoom, and Phase 2 involved publishing open online lessons on the Thai MOOC platform. The sample group used in Pha was 94 lower secondary mathematics teachers with inclusive education programs under secondary education districts across the country. The sample in Phase 2 included 100 learners who registered and ૧૧:૧૫ ચ completed the published online lesson on Thai MOOC. The content of the course includes techniques for producing online mathematics media that supports the learning of blind and low-vision students using accessible/existing tools. This project produced prototype materials and lessons that have been verified by experts for content accuracy and learning management that support the visually impaired. The Cresults of Phase 1 revealed that the teachers who attended the training had improved their knowledge and were satisfied with the training, both the content and the training format, at the highest level. For Phase 2, it was found that the participants were at the highest level of satisfaction with the content and learning format. In addition, participants who completed all activities and passed the certified criteria of 70% had an average score of 85.26 and a standard deviation of 7.63, with a maximum score of 98 points and a minimum score of 70 points. For the implementation of this project, mathematics teachers and other subject teachers were able to produce teaching media and improve teaching media that supports learning for visually impaired and normal students who can benefit from online learning without limits on time and place.Item type: Item , การปรับปรุงกระบวนการทำงานของแผนกซ่อมบำรุงรถยนต์(มหาวิทยาลัยสงขลานครินทร์, 2025) ธนทร กิจตินันท์; กุลภัสร์ ทองแก้ว; Faculty of Engineering (Industrial Engineering); คณะวิศวกรรมศาสตร์ ภาควิชาวิศวกรรมอุตสาหการAccording to a case study conducted by a case study company, general maintenance services encountered substantial delays, with repair times surpassing the standard average in 69.26% of all cars that were serviced. The primary activities that contributed to these delays were engine oil changes, standard service scope, and vehicle inspections. These inefficiencies had a detrimental effect on the service center, leading to consumer dissatisfaction and losing clientele. Consequently, the objective of this research was to enhance the work operations in the automotive maintenance department for general repair services by minimizing the period of time required for maintenance. The study started by utilizing a fishbone diagram to identify the root causes of the delays, which revealed that the primary issues were insufficient spare parts storage, a lack of readily available tools, and redundant workflow steps. Improvement measures comprised the following: the organization of sufficient spare parts storage, the preparation of an adequate supply of parts in advance, the creation of tool panels for easier access, the improvement of workflow processes using ECRS principle, and the establishment of standardized operating procedures. Therefore, the average time per vehicle for standard service scope activities was decreased from 28.33 to 23.79 minutes (a 16.03% decrease), engine oil changes from 30.12 to 25.41 minutes (15.64% decrease), and vehicle inspections from 9.00 to 7.65 minutes (15.00% decrease). Overall, the enhancements resulted in a 15.00% decrease in the average repair time for general maintenance across all service intervals, thereby increasing customer satisfaction with the services providedItem type: Item , การพัฒนาระบบติดตามและควบคุมโรงอบแห้งพลังงานแสงอาทิตย์ ด้วยเทคโนโลยีอินเทอร์เน็ตประสานสรรพสิ่ง กรณีศึกษา : กระบวนการอบแห้งเมล็ดกาแฟ(มหาวิทยาลัยสงขลานครินทร์, 2025) สุรเกียรติ ทองเกียรติ; กุลภัสร์ ทองแก้ว; Faculty of Engineering (Industrial Engineering); คณะวิศวกรรมศาสตร์ ภาควิชาวิศวกรรมอุตสาหการThis research aims to develop a monitoring and control system for a solar-powered drying facility using Internet of Things (IoT) technology for the coffee bean drying process, in order to reduce the drying time. Real-world data was collected from the production process to analyze the causes of delays using flowcharts and fishbone diagrams. It was found that the delay was caused by manual inspection of coffee bean quality and the lack of equipment to monitor moisture and temperature in the drying facility. As a result, the drying process took an average of 21 days and maintaining quality was difficult. To address this issue, the ECRS (Eliminate, Combine, Rearrange, Simplify) principle was applied to improve the coffee bean drying process. A system using IoT technology was developed to monitor temperature, humidity, and electricity usage via smartphone, with data recorded on a cloud platform. Additionally, the system can control the ventilation fan to reduce moisture, which helps shorten the drying time. The results showed that the drying time was reduced to an average of 13 days, a 37.95% reduction. This improvement enhances production efficiency, ensures more consistent coffee bean quality, and reduces production losses. Moreover, the system can be adapted for other agricultural processed products as well.Item type: Item , การออกแบบและพัฒนาระบบเว็ปแอปพลิเคชั่นสำหรับตรวจสอบย้อนกลับทุเรียน(มหาวิทยาลัยสงขลานครินทร์, 2024) จีรนุช อักโขมี; กุลภัสร์ ทองแก้ว; Faculty of Engineering (Industrial Engineering); คณะวิศวกรรมศาสตร์ ภาควิชาวิศวกรรมอุตสาหการThis research aims to design and develop a web application system for durian traceability. The investigators examined relevant Good Agricultural Practices (GAP) standards and the prerequisites for exporting durians to China to ascertain the essential information required for the traceability system. The preparedness of target durian plantations was evaluated in accordance with export criteria, and a tracking system was established for farmers, traders/collectors, and consumers. The findings demonstrated that the durian traceability web application system is applicable for farmers/orchard proprietors, traders/collectors, and consumers, encompassing the durian supply chain. The traceability system includes data from durian cultivation, harvesting, and sale in accordance with export regulations. Testing and user satisfaction assessment indicated that the system could be efficiently utilized for traceability, offering fast access to information. The average result on the test was 4.60 out of 5, which was good. The consumer satisfaction scores were also good, with an average score of 4.97 out of 5.
