The lopsided effects of educational trends on quality education for UN SDG achievement: A case study of neurodiverse and marginalised groups Dowroong Watcharinrat, Innocent Chimankpa Mbadike, Pradit Songsangyos, Arunee Sriphanomwon, Boonchai Aree-uea, et al. Multidisciplinary Science Journal, 2026 The Lopsided Effects of Educational Trends on Quality Education for UN SDG Achievement: A Case Study of Neurodiverse and Marginalized Groups examined the uneven impact of educational trends on Quality Education for promoting the United Nations Sustainable Development Goals (SDGs) among neurodiverse students and marginalized communities. A study of 302 participants from a Nigerian community school revealed that educational trends have a moderate impact on promoting SDGs for both groups. For neurodiverse students, the trends posed health risks, such as fatigue from excessive screen time, while standardized testing methods were deemed unsuitable. Among marginalized groups, linguistic minorities faced barriers to accessing education. The research identified alternative educational approaches that can better promote SDGs, emphasizing teacher training programs for inclusive education and user-centered EdTech designs. The study found that educational trends have both benefits and drawbacks in supporting the promotion of SDGs, requiring accommodations to strike a balance. By acknowledging these challenges and implementing tailored solutions, educators and policymakers can create more inclusive learning environments that support the achievement of SDGs for all students, regardless of their abilities or backgrounds. This research highlights the need for a nuanced approach to educational trends, one that prioritizes equity and accessibility The results of the research showed that the lopsided effects of educational trends on promoting the United Nations SDGs in relation to neurodiverse students, overall, was at a moderate level. The lopsided effects of educational trends on promoting the United Nations SDGs in relation to marginalized and vulnerable groups, overall, was at a moderate level. Alternative educational approaches can better promote the SDGs and address the needs of neurodiverse learners and marginalized communities. Meanwhile, multiple linear regression analysis was employed to further strengthen the research’s tone.
Efficiency of drip irrigation combined with Bacillus bacteria application in enhancing growth and yield of Jinda chilis Phraomas Charoenrak, Dowroong Watcharinrat, Suwonnakan Supamattra, Purin Akkarakultron, Thanwamas Phasinam, et al. Multidisciplinary Science Journal, 2025 The purpose of this study was to evaluate the efficiency of different drip irrigation schedules combined with the application of Bacillus bacteria (B. amyloliquefaciens BB165) on the growth and yield of Jinda chili plants. An experiment was conducted to compare four irrigation treatments: two sessions of 10 minutes each (control), three sessions of 5 minutes each, two sessions of 10 minutes combined with Bacillus bacteria, and three sessions of 5 minutes combined with Bacillus bacteria. Jinda chili seedlings were transplanted into plastic pots and treated accordingly. Plant heights were measured every 15 days, while yield weights were recorded every 30 days. Fresh plant and root weights were measured 90 days posttransplantation. The results indicated that three sessions of 5 minutes of drip irrigation significantly conserved water, reducing usage by up to 23.59% compared to the control, and increased plant heights by 6.81% to 14.00%. The combination of two sessions of 10 minutes of drip irrigation with Bacillus bacteria produced the highest fresh plant (199.75 g) and root weights (105.00 g). Yield weights showed no significant differences across treatments, though specific treatments exhibited higher yields at different intervals. Notably, three sessions of 5 minutes of drip irrigation with Bacillus bacteria resulted in the highest yield weight at 30 days (212.76 g), while two sessions of 10 minutes with Bacillus bacteria showed the best results at 90 days (184.09 g). In conclusion, optimizing drip irrigation schedules and integrating Bacillus bacteria can significantly enhance water efficiency and plant growth in chili cultivation. This study demonstrates that strategic irrigation practices combined with microbial interventions can lead to improved growth outcomes in chili plants.
Music attitudes and career aspirations: A study of master's degree students in private universities Dowroong Watcharinrat, Ek-karach Charoennit, Thanaphan Boonyarutkalin, Pattraporn Aupaiboon, Sujin Butdisuwan, et al. Multidisciplinary Science Journal, 2025 This research aimed to explore the music attitudes and career choices of master’s degree students within the Faculty of Liberal Arts at private universities, with a focus on understanding the relationships among these variables. A total of 73 master’s degree students enrolled since 2021 were surveyed via questionnaires as research instruments. Statistical analyses, including frequency, percentage, mean, standard deviation (S.D.), and correlation coefficient (r), were performed to analyze the data. The findings revealed significant insights into students' attitudes toward music and their career preferences. With respect to music attitudes, the students demonstrated a profound belief in the societal importance of music and its role in enhancing the livability of society. Additionally, they expressed admiration for music professionals and recognized the significance of music-related professions such as musicians and music teachers. In terms of career choices, students prioritized working in organizations fostering inclusivity and embracing diversity among colleagues. They also emphasized the importance of studying subjects aligned with their strengths and aspirations and sought stability in leading companies or organizations. Surprisingly, the research concluded that there was no significant correlation between students' attitudes toward music and their career choices within this cohort. This study provides valuable insights for educators and career counselors, highlighting the nuanced dynamics between students' attitudes toward music and their career aspirations and indicating that these aspects may not necessarily be interlinked in this particular academic context.
AI-Based Aerial Camera Calibration and 3D Reconstruction Accuracy Evaluation Jittiphan Changkaew, Prasartporn Wongkamchang, Chamnan Pedchote, Khongdet Phasinam Advances in Artificial Intelligence and Machine Learning, 2025 Accurate camera calibration is a cornerstone of aerial imaging, essential for precise 3D reconstruction, mapping, and motion estimation. Traditional calibration methods often depend on predefined objects and periodic recalibration, which are impractical in dynamic aerial environments. This study investigates the potential of AI-based calibration methods, specifically GeoCalib, CTRL-C, and DeepCalib, to address these challenges. Using the ISPRS Vaihingen dataset, evaluate these methods against the conventional approach. The research focuses on intrinsic parameter estimation and its impact on 3D reconstruction accuracy. Our findings reveal that CTRL-C achieved the highest precision, with a mean reconstruction error of 1.59e10−5 , significantly outperforming GeoCalib (1.0549) and DeepCalib (0.2110). Additionally, DeepCalib demonstrated strong performance in minimizing Chamfer Distance (0.4220) and Hausdorff Distance (0.2502), while GeoCalib exhibited broader error distributions. These results underscore the superior capability of AI-based techniques in delivering accurate and reliable calibration for aerial imaging systems.

Multidisciplinary Science Journal, 2024 The objectives of this research are: 1) to study the skill levels and development needs of twenty-first century master's degree students, 2) to compare these skill levels and development needs by classifying students according to variables such as gender, age, work experience, and institution of graduation, and 3) to study the relationship between the level of skills and the need for developing twenty-first century skills of master's degree students. Questionnaires were distributed to master's degree students in the Faculty of Liberal Arts at a private university who studied from 2021 onward. A total of 80 questionnaires were distributed, and 73 responses were received. The statistical methods used in the research include frequency, percentage, mean and standard deviation, independent sample t-test, one-way ANOVA, and the correlation coefficient of variables (r). The research results found that: 1) the top three twenty-first century skills of students are media literacy, social skills, and information literacy. The top three needs for developing twenty-first century skills are cooperation, creative thinking, and communication skills. 2) The comparison of twenty-first century skills among students revealed no significant differences in skill levels based on gender and age. However, significant differences were found in skill levels based on the educational institutions and fields of study completed at the bachelor's degree level. No significant differences were found in the need for developing twenty-first century skills based on gender, age, educational institution, and field of study at the bachelor's degree level. 3) The level of twenty-first century skills is not related to the need for developing twenty-first century skills.
