A child manikin for Cardiopulmonary Resuscitation (CPR) training includes the trachea mechanism, neck mechanism, lung mechanism, heart pump mechanism, artificial skin, and sensor system. All components work together to function similar to a real child. It can be used to practice heart pumping and resuscitation. The manikin has been designed and verified by resuscitation experts. It has a system to evaluate the accuracy of the training and display the results on the computer for real-time monitoring.

A new colorimetric assay for the rapid detection of tannic acid in beverage samples based on displacement phenomenon of aggregated gallic acid-modified platinum nanoparticles is developed for the first time. PtNPs were functionalized with gallic acid, promoting the formation of the green-hued aggregated nanoparticles. While colorimetry offers a rapid method for identifying tannic acid, challenges remain in sensitivity and accuracy of detection on the PtNPs colorimetric probe, particularly in the presence of anthocyanin interferences. To address this, we developed a sample preparation method to degrade anthocyanin in beverages. Tannic acid was easily displaced onto the gallic acid-coated PtNPs surfaces, causing dispersion and resulting in a visible color change from green to orange−brown. Under the optimal conditions, the colorimetric sensor exhibited a linear response in the range of 1−2,000 µmol L−1 (R2 = 0.9991). The limit of detection (LOD) and the limit of quantification (LOQ) were found at 0.02 and 0.09 µmol L−1, respectively. The proposed sensor expressed superior selectivity over other interfering substances and demonstrated excellent precision with a relative standard deviation (RSD) of 1.00%−3.36%. More importantly, recoveries ranging from 95.0−104.7% were obtained, indicating the capability of proposed colorimetric sensor to detect tannic acid rapidly and accurately in real beverage samples.

This project aims to design and develop an eye-tracking system to facilitate communication for paralyzed immobile patients. The system is designed to enable patients to convey their needs to caregivers or family members by detecting and tracking eye movements using the Tobii Eye Tracker 5 device. This approach serves as an alternative communication method, replacing the physical movement or speech of paralyzed patients. The system effectively detects and tracks eye movements at a distance of 55 to 85 centimeters and is designed for installation on a computer to ensure ease of use. The program interface consists of three main sections: (1) a set of emotions, (2) a set of needs, and (3) a set of additional needs. It supports input from a virtual keyboard in both Thai and English and allows users to specify additional needs through eye-tracking-enabled typing. Furthermore, the system can generate synthetic speech for text that is difficult to pronounce aloud, send notification messages via the Line application, and store usage data in a database presented in a dashboard format. System testing revealed that the optimal detection distance ranges from 65 to 75 centimeters, as this range yields an error rate of no more than 1 percent. The system accurately responds to eye movements for communication through sound within 3 seconds when interacting with various function buttons. This eye-tracking system effectively enables paralyzed immobile patients to communicate their emotions and needs, facilitating better understanding and interaction between patients and their caregivers or family members.

This thesis project was conducted to identify the optimal conditions for producing concentrated butterfly pea juice using vacuum evaporation to preserve key compounds in butterfly pea flowers, such as anthocyanins—natural pigments with high antioxidant properties. The study applies a Box-Behnken Design, a statistical method that facilitates analysis of multiple factors. The research focuses on the ratio of dried butterfly pea flowers to water, extraction temperature, and evaporation temperature, each of which has a direct effect on the preservation of key compounds, color, aroma, and flavor. The results indicate that using a dried flower-to-water ratio of 1:15, an extraction temperature of 60°C, and an evaporation temperature of 40°C under low pressure can minimize the loss of essential compounds and best retain the properties of the concentrated butterfly pea juice. Findings from this research provide a foundation for developing an industrial production process for concentrated butterfly pea juice and enhance the potential for creating new products from butterfly pea flowers.
