The benefits of this research include helping viewers recognize and understand PTSD and its treatment for prevention, as well as utilizing this motion graphic media model to educate on other disorders.

EVALUATING THE EFFECTIVENESS OF CROSS-CURRICULAR PROJECT-BASED LEARNING INTEGRATED WITHIN THE I-MAP FRAMEWORK ON STUDENTS’ LEARNING OUTCOMES AND ENGAGEMENT

2025-09-17T12:31:56+07:00

This paper evaluated a project-based learning (PBL) model that integrates the “Technology and Innovation” course with a capstone-style project within the I-MAP framework and Backward Design principles. Participants were 32 fourth-year Industrial Technology students who worked in teams to complete a semester-long project. Data were collected through pretest–posttest, analytic rubrics, observational checklists, and focus-group interviews, and analyzed using ANCOVA and linear mixed models. The findings indicate substantial educational gains in theoretical knowledge and project quality. Although some between-team comparisons did not yield statistically significant differences, the effect sizes were large, demonstrating meaningful impacts of the learning model—particularly in large-class PBL contexts. Mixed-model analysis further revealed that team-level contextual factors significantly enhanced the explained variance in students’ behavioral outcomes. Qualitative evidence corroborated the quantitative results, showing that students developed greater intrinsic motivation, demonstrated improved ability to transfer knowledge into real-world practice, and strengthened teamwork skills—all of which align with the observed improvements in cognitive and behavioral learning outcomes.

THE RELATIONSHIP BETWEEN MUSCULOSKELETAL DISORDERS AND COMPUTER-RELATED ERGONOMIC RISKS AMONG PERSONNEL AT A PRIVATE HIGHER EDUCATION INSTITUTION

2025-12-18T06:04:42+07:00

This cross-sectional study aimed to assess ergonomic risks and determine the relationship between ergonomic risks and musculoskeletal disorders (MSDs) among 77 computer-using personnel at a private higher education institution. The results showed that the majority of participants were male (63.63%) and aged between 31-35 years (41.55%) ( = 34.18, S.D. = 6.25). Most participants had a body weight between 61-70 kg (37.66%) ( = 65.12, S.D. = 13.69) and a height of less than 160 cm (41.56%) ( = 164.38, S.D. = 6.50). Regarding Body Mass Index (BMI), 45.45% had a BMI greater than 30 kg/m²followed by 41.56% in the 18.50-22.90 kg/m2 range ( = 24.03, S.D. = 1.06). Most had 1-2 years of work experience (25.97%) ( = 2.68, S.D. = 1.23) and worked 5 days per week (66.23%). The ergonomic risk assessment using the Rapid Office Strain Assessment (ROSA) indicated that the majority of support staff (62 persons, 80.52%) had scores between 5 and 7, classified as high risk, requiring further workstation analysis for improvement. This was followed by 15 persons (19.48%) with scores between 8 and 10. Regarding MSDs over the past 12 months, the most frequently reported symptoms were in the wrist/hand (80.52%), followed by the neck (77.92%) and lower back (71.42%), respectively. Furthermore, a statistically significant association was found between ergonomic risks and MSDs in the wrist and hand regions (p-value < 0.001). Therefore, urgent workstation analysis and improvements are recommended. The study concludes that personnel are frequently exposed to ergonomic risks, as assessment scores consistently exceeded the low-risk threshold (scores > 4), necessitating ongoing monitoring.

DEVELOPMENT OF LIGHTWEIGHT TOOLS FOR FRUIT WRAPPING AND HARVESTING

2025-12-02T05:15:14+07:00

This research presents the development of a lightweight and user-friendly fruit wrapping and harvesting tool suitable for fruit trees with low-to-medium height canopies. The developed tool utilizes a 1 inch diameter aluminum tube weighing 400 g, extendable up to 3 m in length, featuring an internal wire mechanism connected to a grip handle. For fruit wrapping, the mechanism releases a rubber band to secure a plastic bag around the fruit stem, thereby protecting it from insects. For fruit harvesting, the device is equipped with a downward-facing acute-angled blade to cut the fruit stem and a net to collect the fruit. Performance tests were conducted with three trials on mangoes (Khieo Sawoei variety) and santols, and the average operation times were recorded. For mangoes with a circumference of approximately 20–21 cm and a length of 10–11 cm, the average times for wrapping and harvesting were 20.26 s/fruit and 30.37 s/cycle, respectively. In each harvesting cycle, no more than 2–3 fruits were collected, with a total weight not exceeding 1,800 g. For santols with a circumference of about 28–30 cm, wrapping and harvesting took an average of 11.64 s/fruit and 5.31 s/cycle, respectively, with a capacity of up to three fruits per cycle and a total weight of approximately 1,000 g. The results indicated that round fruits required less operation time than elongated fruits. The performance evaluation demonstrated that the average time for fruit wrapping and harvesting of mango and santol was consistently lower than the benchmark values obtained from farmers. The t-test results further confirmed that the developed wrapping and harvesting tool significantly reduced the time required for mango and santol compared with the standard reference values, with significance at the 0.01 level.

THE SUITABILITY STUDY OF SURFACE WATER SOURCES FOR DESIGNING SUB-DISTRICT WATER SUPPLY SYSTEMS: A CASE STUDY OF NONG PHO SUB-DISTRICT MUNICIPALITY, KHUAN KHANUN DISTRICT, PHATTHALUNG PROVINCE

2025-12-13T12:13:35+07:00

The objectives of this research were to 1) analyze the suitability of surface water sources regarding quantity, quality, and balance, 2) design guidelines for a surface water supply system to integrate with the existing groundwater system of Nong Pho Subdistrict Municipality, Khuan Khanun District, Phatthalung Province. A mixed-methods approach was employed, involving field surveys, hydrological data collection, and laboratory water quality testing. The results revealed that the case study of the surface water source (excavated pond, Moo 6 Ban Khuan Phli, area 16,000 sq.m., average depth 3-5 m) had sufficient water storage capacity year-round. With total losses from evaporation and seepage accounting for approximately 30%, the source is suitable as a supplementary raw water supply during the dry season. Regarding raw water quality, the overall condition was good, with Dissolved Oxygen (DO) at 9.2 mg/L and Biological Oxygen Demand (BOD) at 0.8 mg/L. However, the average pH was 5.8, with turbidity at 5.2 NTU and Fecal Coliform bacteria contamination at 230 MPN/100 mL. Meanwhile, the existing groundwater system in Moo 3 encountered Total Dissolved Solids (TDS) of 680 mg/L, exceeding the drinking water standard. Consequently, a conventional water treatment system was designed, emphasizing pH adjustment (6.5-7.5), coagulation-flocculation, rapid sand filtration, and effective disinfection maintaining free residual chlorine of at least 0.2 mg/L. The study results demonstrated that integrating treated surface water with existing groundwater could effectively resolve the excessive TDS issue, sustainably enhance community water security, and provide a cost-effective solution.

DEVELOPMENT OF PROJECT-BASED LEARNING MODEL INTEGRATING THE FOUR NOBLE TRUTHS AND STRATEGIC DESIGN (DSNM-PBL) TO ENHANCE CAREER AND TECHNOLOGY SKILLS FOR LOWER SECONDARY STUDENTS

2025-12-12T08:59:26+07:00

The objectives of this research were to: 1) develop and determine the efficiency of the DSNM-PBL learning management model integrating the Four Noble Truths and Strategic Design for teachers; 2) compare teachers' active learning and innovative management competencies before and after using the model; and 3) study teachers' satisfaction with the model. A distinct feature of this model, differentiating it from general Project-Based Learning (PBL), is the emphasis on cognitive processes based on Buddhist principles to deeply analyze the root causes of problems prior to designing innovations. The target group consisted of 23 teachers at Wat Si Somboon Municipal School during the 2025 academic year. The research instruments included: 1) a workshop manual for the DSNM-PBL model, 2) a knowledge and competency assessment for instructional plan writing, and 3) a satisfaction questionnaire. Data were analyzed using mean, standard deviation, and t-test for dependent samples. The research findings were as follows: 1) The DSNM-PBL learning management model for teachers consists of four steps: Problem Analysis (Dukkha), Cause and Potential Finding (Samudaya), Innovation Goal Setting (Nirodha), and Strategic Learning Design (Magga). The model’s efficiency (E1/E2) was 83.48/85.65, which met the specified 80/80 criterion. 2) Teachers' active learning and innovative management competencies after using the model were significantly higher than before using the model at the .05 level. 3) Teachers’ satisfaction with the learning management model was at the highest level. Teachers reflected that the DSNM model enabled systematic and profound instructional design, capable of effectively connecting local wisdom to innovation.
