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, Khongdet Phasinam 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.
Long-Term Electricity Demand Forecasting for Thailand’s Small Business Sector: An LSTM-Based Approach Puttiphong Jaroonsiriphan, Kayun Chantarasathaporn, Khongdet Phasinam International Journal of Emerging Research in Engineering Science and Management, 2026 Accurate electricity demand forecasting is essential for Thailand’s energy system planning, particularly for the small business sector, whose consumption exhibits high variability (coefficient of variation: 26.34%). This study develops a Long Short-Term Memory (LSTM) model to forecast monthly electricity consumption of Thailand’s small business sector over a 12-month horizon from September 2025 to August 2026. The analysis is based on 284 months of historical consumption data (January 2002–August 2025) obtained from official national statistics. The forecasting framework employs Min–Max normalization and a supervised learning formulation with a 12-month lookback window. The dataset is chronologically divided into training (80%) and testing (20%) subsets, and model performance is evaluated using Root Mean Squared Error (RMSE) and Mean Absolute Percentage Error (MAPE). The optimized LSTM model achieves strong forecasting accuracy, with a training RMSE of 93.93 and MAPE of 5.45%, and a testing RMSE of 143.68 and MAPE of 6.25%. These results meet the criterion for highly accurate forecasting (MAPE < 10%), demonstrating the model’s ability to capture long-term trends and seasonal patterns while generalizing well to unseen data. The findings highlight the suitability of LSTM-based models for long-term electricity demand forecasting in high-volatility small-business sectors and underscore their practical relevance for energy planning and policy development in Thailand.
Real-Time Monitoring and Positioning of Agricultural Tractors Using a Low-Cost GPS and IoT Device T. Phasinam, K. Phasinam, A. U-kaew, K. Piyathamrongchai, R. Hataitara, et al. International Journal of Geoinformatics, 2025 This research aims to develop a low-cost GPS receiver device for positioning agricultural tractors, incorporating Differential GPS (DGPS) technology for enhanced accuracy using the Open-Source GIS Stack (OSGS). Integrated with Internet of Things (IoT) technology, the device was tested to receive GPS data and other relevant information, including geographic coordinates (latitude and longitude), tractor speed, tractor direction, date, time, and the number of satellites receiving signals. The DGPS setup involves using one receiver as a base station and another on the tractor, where the base station provides correction data to improve positioning accuracy. The data collected by the receiver is transmitted to a signal processing device for mapping the coordinates, creating a route of the tractor's movement that is displayed on a real-time Web Map Application. This process includes error correction to ensure high accuracy. The IoT device was installed on the left rear wheel of the agricultural tractor. Test results show that the data from the developed device has an accuracy of around 30-90 centimeters, which is acceptable and sufficient for agricultural tractor positioning applications. Furthermore, this system enables real-time monitoring of the tractor's operations.
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, Khongdet Phasinam 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.
