Some musicians are hearing impaired, some have finished their careers, but some continue to work, and it is much harder for them to be deaf than for musicians who are not. Some use hearing aids in their daily lives and use in-ear monitors in their live performances, which seem normal, but in their in-ears they only hear the metronome and drums. How can we improve the performance of in-ear monitors to near normal?
นักดนตรีบางคนที่พิการทางการได้ยิน บางคนจบอาชีพการงาน แต่บางคนยังคงทำงานต่อไปโดยที่หูหนวกนั้นยากกว่านักดนตรีปกติมาก บางคนใช้เครื่องช่วยฟังในชีวิตประจำวันและใช้เครื่องช่วยฟังแบบอินเอียร์ในการแสดง สดซึ่งดูเหมือนปกติ แต่ในอินเอียร์ของพวกเขา ได้ยินเพียงเครื่องเมตรอนอมและกลองเท่านั้น ถ้าพวกเขาสามารถใช้อินเอียร์มอนิเตอร์ในการทำงานได้แต่ยังไม่สามารถทำได้อย่างเต็มประสิทธิภำพเกิดจากอะไรและแก้ไขอย่างไร

This research aims to investigate the adulteration of Khao Dawk Mali 105 rice based on storage age using Near-Infrared Spectroscopy (NIRS) with Fourier Transform Near-Infrared Spectroscopy (FT-NIR) in the wavenumber range of 12,500 – 4,000 cm-1 (800 – 2,500 nm). Storage duration significantly impacts the quality of cooked rice. This research is divided into two parts: 1) to investigate the feasibility of separating rice according to storage age (1, 2, and 3 years) using the best model created by an Ensemble method combined with Second Derivative, which achieved an accuracy of 96.3%. 2) To investigate adulteration based on storage age by adulterating at 0% (all 2- and 3-year-old rice), 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% (all 1-year-old rice). The best model was created using Gaussian Process Regression (GPR) combined with Smoothing + Multiplicative Scatter Correction (MSC), with coefficients of determination (r²), root mean square error of prediction (RMSEP), bias, and prediction ability (RPD) values of 0.92, 8.6%, 0.9%, and 3.6 respectively. This demonstrates that the adulteration model can be applied to separate rice by storage age (1, 2, and 3 years). Additionally, the color values of rice with different storage ages show differences in L* and b* values.

The researcher aims to develop bagasse mixed with molasses as a smoking material for meat, enhancing its unique aroma and flavor. This innovation caters to the food industry and consumer demand while adding value to sugar mill byproducts, reducing waste, and promoting efficient resource utilization.

Air pollution, particularly PM2.5, is a major environmental and public health concern in Bangkok. Instead of predicting PM2.5 levels, this project aims to identify the most significant factors influencing PM2.5 concentration. By analyzing historical air quality, weather, and other environmental data, we will determine which variables—such as temperature, humidity, wind speed, or other pollutants—have the greatest impact on PM2.5 fluctuations.
