The Department of Engineering Education at KMITL offers courses in power electronics laboratory practices, which require the use of expensive imported training kits. This results in a loss of national revenue due to the purchase of these imported kits. Therefore, the developers propose a power electronics training kit that offers equivalent or superior functionality to the imported ones while being more cost-effective, making it suitable for student experiments.
การเรียนการสอนรายวิชาอิเล็กทรอนิกส์กำลังในปัจจุบัน มีการใช้การจำลองการทำงานด้วยโปรแกรมคอมพิวเตอร์ เนื่องจากขาดแคลนชุดทดลองจริง ซึ่งการทดลองกับอุปกรณ์จริงยังมีจำเป็นเป็นอย่างยิ่ง ดังนั้นจึงมีการริเริ่มในการสร้างด้วยตนเองเพื่อให้สามารถนำมาใช้ในการเรียนการสอนได้

The development of skin-on-a-chip models plays a crucial role in research for drug and cosmetic development. Traditional approaches often utilize two-dimensional (2D) methods that rely on culturing cells on flat surfaces, resulting in a lack of complexity in skin structure and realistic cell interactions. Moreover, traditional methods have limitations in mimicking fluid flow and nutrient circulation, which affects the accuracy of pharmaceutical testing and the prediction of drug effects. This has led to the advancement of three-dimensional (3D) skin models using new microfluidic technology, enhancing the realism of skin structure by replicating both the epidermis and dermis layers, as well as simulating fluid flow similar to physiological conditions in the human body. The design of 3D systems allows for more realistic cell arrangement and interactions, enabling better simulation of skin functions and increasing the accuracy in evaluating the effects of various substances on cell responses, including absorption, inflammation, and wound healing. Therefore, the development of three-dimensional (3D) skin models not only addresses the limitations of traditional methods but also represents a significant step forward in creating models that can be effectively applied in drug testing and pharmaceutical product development.

This research gives a comprehensive overview of the use of antibiotics in livestock production, highlighting both the benefits and the risks associated with their use. The benefits, such as improving immunity, digestion, and reducing infections, are contrasted with the growing concern over antibiotic residues and the development of drug resistance. The shift towards alternatives like probiotics is explored as a sustainable solution, with a specific focus on lactic acid bacteria (LAB) found in the digestive systems of livestock. Thailand’s regulations, which control antibiotic use in animal feed, are also discussed, setting the stage for the study on LAB as a potential replacement for imported probiotics. 1. Use of Antibiotics in Livestock: Antibiotics have been used to promote growth, improve digestion, and prevent infections in livestock. However, the improper use of antibiotics can lead to residues in animal products and the development of drug-resistant bacteria. 2. Global Trends in Antibiotic Use: Many countries, like the European Union and Japan, have banned antibiotics as growth promoters, while others, like China and the U.S., are planning similar bans. 3. Thailand's Approach: Thailand has implemented a regulation since September 2020 to control the use of antibiotics in animal feed, requiring control at both feed mills and farms that mix their own feed. 4. Probiotics as an Alternative: Probiotics, particularly lactic acid bacteria (LAB), are being studied as an alternative to antibiotics. LAB are naturally found in the digestive tracts of livestock and are considered beneficial for maintaining gut health and replacing the need for antibiotics. The study examines the potential of LAB from Thai livestock (broilers, pigs, and cattle) as a sustainable alternative to imported probiotics, aiming to overcome issues like low survival rates of foreign probiotics in practice.

This study aimed to investigate the efficacy of lime containing more than 50% calcium oxide and not less than 29% magnesium oxide in enhancing water alkalinity for Pacific White Shrimp (Litopenaeus vannamei) aquaculture. The experiment was conducted at concentrations of 0, 5, 10, 15, and 20 ppm over a 48-hour period, with data collected at 0, 3, 6, 12, 24, 36, and 48 hours. Results demonstrated that lime exhibited high dissolution efficiency (65-86%) within the first hour and reached complete dissolution (98.5-98.6%) within 6 hours. The pH values initially increased proportionally with lime concentration, gradually decreased during 3-12 hours, before stabilizing. Total alkalinity showed significant increase during the first 3-6 hours and remained stable until the end of the experiment. Statistical analysis revealed that both concentration and time significantly affected all parameters (p < 0.001)
