This research aimed to isolate and culture four strains of lactic acid bacteria (LAB) isolated from fermented foods. The antimicrobial activity of the lactic acid bacteria was studied using the agar spot method and the antibiotic resistance properties of the lactic acid bacteria were studied using the agar overlay diffusion method. The results showed that each strain of lactic acid bacteria had different levels of antimicrobial activity and antibiotic resistance, which are safety properties of probiotic microorganisms.
จุลินทรีย์โพรไบโอติก (Probiotic) หมายความว่า จุลินทรีย์ที่มีชีวิต ซึ่งเมื่อร่างกายได้รับในปริมาณที่เพียงพอจะทำให้เกิดผลที่เป็นประโยชน์ต่อสุขภาพ อาหารที่มีการใช้จุลินทรีย์โพรไบโอติกต้องได้รับอนุญาตจากสำนักงานคณะกรรมการ อาหารและยา และ ต้องใช้จุลินทรีย์ตามที่กำหนดไว้ ดังนั้นการวิจัยนี้จึงนำเชื้อแบคทีเรียแลคติกที่แยกได้จากอาหารหมัก 4 สายพันธุ์ มาศึกษาฤทธิ์การต้านเชื้อแบคทีเรียก่อโรคในอาหาร และ ศึกษาสมบัติการดื้อยาของเชื้อแบคทีเรียแลคติก

This project aims to propose a design for a red offal processing room in a pork processing plant that processes 500 pigs per day or 80 pigs per hour. Each pig weighs approximately 105 kilograms, with 3.47% of the weight consisting of red offal. The process involves separating liver, gall bladder, heart, lungs, spleen, and kidneys as required. These parts are then chilled in cold water to reduce their temperature to below 7°C before packaging and sealing. Sorting is based on the number of pieces and weight, depending on the type of product. The processing times of sorting chilling and packaging vary depending on the product's type and size. The design was developed using data collected from the current production line and referenced standards. The room layout was planned using Systematic Layout Planning (SLP) principles to analyze activity relationships within the room and define functional areas. Equipment sizes and the required number of operators were calculated to ensure optimal use of space. The red offal processing room was designed with an area of 56 square meters. After the layout design was completed, a 3D model was created using SketchUp 2024, and the workflow and operations were simulated and analyzed using Flexsim 2024

This special project aims to develop and compare the performance of gold price prediction models using quantitative variables and news text data. The study incorporates nine key predictors, including Brent crude oil prices, WTI crude oil prices, silver prices, platinum prices, the U.S. Federal Reserve's policy interest rate, the Nikkei 225 index, the Dow Jones Industrial Average, the S&P 500 index, and daily news articles from Bangkok Business News. Relevant news data will be processed using Natural Language Processing (NLP) techniques and integrated with three predictive models: Gradient Boosting, Machine Learning Models, and Regression Analysis. The model performance will be evaluated using three key metrics: Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and the Coefficient of Determination (R*). This research aims to develop a predictive model that effectively utilizes both quantitative variables and news data to enhance gold price forecasting, providing valuable insights for investors and analysts.

The project uses artificial intelligence (AI) and deep learning to develop a smart police system (Smart Police) to analyze the identity of individuals and vehicles suspected of involvement in crimes. The system uses CCTV cameras to detect people with concealed weapons and track vehicles involved in crimes. The system also sends alerts to the police when a crime is detected. The Smart Police system is a collaboration between the Faculty of Engineering, King Mongkut's Institute of Technology Ladkrabang, the Provincial Police Region 2, the Chachoengsao Foundation for Development, and the Smart City Office of Chachoengsao Province. The system is designed to prevent and deter crime, increase public safety and order, and build a network of cooperation between the government, the private sector, and the community. The system is currently under development, but it has the potential to be a valuable tool for law enforcement. The system could help to reduce crime and improve public safety in Chachoengsao Province and other parts of Thailand.
