The forest firefighting suit consists of the following components and uses: The forest firefighting suit is designed and developed to be suitable for the behavior of the officers and the conditions of the work area, consisting of a shirt and pants. The material used in the sewing of the suit is aramid fabric, which has the property of being able to prevent the spread of fire, to prevent the officers from burning while performing their duties in the event that the forest fire spreads close to them, which is different from the current suits that cannot prevent fires. The shirt is designed with a mesh on the side of the body to release internal heat so that air can circulate well. The sleeves at the elbows have a support point to prevent contact with the ground or obstacles. The collar has a slot for a portable fan and a fan air circulation channel on the back, which can be turned on while performing forest firefighting duties, helping to prevent the body temperature from getting too hot, reducing the risk of heatstroke. When the fan battery runs out, it can be removed for charging and put back in when needed. The pants are designed with mesh on the inside or in blind spots to release internal heat so that air can circulate well. The pants at the knees have a support point to prevent contact with the ground or obstacles. The forest firefighting suit, consisting of a shirt and pants, has been designed and developed to be able to be produced domestically, reducing imports from abroad
ปัญหาไฟป่าที่ทวีความรุนแรงขึ้นเรื่อย ๆ ส่งผลกระทบในหลายๆด้านโดยเฉพาะผู้ที่พักอาศัยบริเวณใกล้ไฟป่าต้องเผชิญกับปัญหาด้านสุขภาพที่เกิดจากฝุ่น PM2.5 ประกอบกับทางภาครัฐยังขาดแคลนบุคลากรเจ้าหน้าที่ ที่มีความชำนาญในการดับไฟป่า รวมถึงยังขาดชุดดับไฟป่าที่เป็นชุดสามารถกันไฟได้เหมาะสมต่อการดับไฟ เนื่องจากในปัจจุบันชุดที่เจ้าหน้าที่อุทยาน และเจ้าหน้าที่ศูนย์ดับไฟป่า สวมใส่ในการปฏิบัติหน้าที่นั้นเป็นชุดลายพลาง กางเกงกับเสื้อแบบทั่วไป ไม่สามารถปกป้อง หรือกันไฟเมื่อไฟมาถึงระยะประชิดตัวได้ในระดับที่เหมาะสม ซึ่งสาเหตุนี้ส่งผลให้เจ้าหน้าที่บางรายได้รับอันตรายถึงขั้นไฟคลอกได้ ผู้วิจัยจึงได้เล็งเห็นถึงความสำคัญในการออกแบบและพัฒนาชุดดับไฟป่า เพื่อให้เจ้าหน้าที่อุทยาน และเจ้าหน้าที่ศูนย์ดับไฟป่า สามารถสวมใส่ปฏิบัติหน้าที่ได้อย่างปลอดภัย ช่วยลดอุปสรรคในการดับไฟป่าและปฏิบัติหน้าที่ได้อย่างเต็มประสิทธิภาพมากยิ่งขึ้น

Bacteriocins are microbial peptides that demonstrate potency against pathogens. This study evaluated the inhibitory effects on pathogens and characterized the bacteriogenomic profile of strain TKP1-5, isolated from the feces of Anas platyrhynchos domesticus. Strain TKP1-5 was characterized using phenotypic traits, 16S rRNA sequencing, and Whole-Genome Sequencing (WGS). It exhibited growth in the presence of 2-6% NaCl, temperatures of 25-45°C, and pH levels ranging from 3 to 9. Based on ANIb, ANIm, and dDDH values, strain TKP1-5 was identified as Lactococcus lactis. Whole genome analysis revealed that strain TKP1-5 harbors the Nisin Z peptide gene cluster with a bit-score of 114.775. The antimicrobial spectrum of bacteriocin TKP1-5 showed inhibitory effects against pathogenic bacteria including Pediococcus pentosaceus JCM5885, Listeria monocytogenes ATCC 19115, Enterococcus faecalis JCM 5803T, Salmonella Typhimurium ATCC 13311ᵀ, Aeromonas hydrophila B1 AhB1, Streptococcus agalactiae 1611 and Streptococcus cowan I. Genomic analysis confirmed L. lactis TKP1-5 as a non-human pathogen without antibiotic resistance genes or plasmids. Furthermore, L. lactis TKP1-5 contains potential genes associated with various probiotic properties and health benefits. This suggests that L. lactis TKP1-5, with its antibacterial activity and probiotic potential, could be a promising candidate for further research and application in the food industry.

This research aimed 1) to study the problems and needs in the packaging design of the community enterprise group 2) to develop packaging for the community enterprise group 3) to study the satisfaction with the packaging design of the members of the Klong Dan Shrimp Paste Community Enterprise Group 3 Klong Dan Subdistrict, Bang Bo District, Samut Prakan Province, consisting of 9 members The study found that the community enterprise group faced the problem of lacking suitable packaging for souvenirs and had a need to develop packaging that is appropriate for this purpose. The packaging material selected was paper, with a rectangular shape including a handle for portability It can be folded for easy transportation and stacked for storage, while maintaining durability The packaging color used was light brown, and the label color was white The label included the following details: shrimp paste recipe, ingredients, manufacturing and expiration dates, the background of the community enterprise group, a QR code, phone number, a short story, group name, production site, as well as illustrations of the group’s location and red krill. The results of developing packaging for the community enterprise group indicated that the new packaging design increased the credibility of the product, building customer confidence in the product. Regarding the satisfaction with the packaging design among the group members, it was found that Packaging Design 1 had the highest level of satisfaction (x ̅ = 4.57, S.D. = 0.22). Among the aspects, color received the highest satisfaction score (x ̅ = 4.74, S.D. = 0.06), followed by the label (x ̅ = 4.69, S.D. = 0.10), while the lowest was the properties aspect, which was rated at a moderate level of satisfaction (x ̅ = 3.83, S.D. = 1.58), respectively.

The railway brake system usually uses compressed air brake system which uses high-pressure air to press the brake shoe on the surface of the wheel to reduce the speed of the train. Repeated friction generates heat at the contact surface, increasing thermal stress on the cast iron brake shoe. The purpose of this study is to investigate the thermal stress on a prototype of cast iron brake shoe using the finite element method compare the analytical results to the actual brake shoe and redesign a brake shoe prototype to reduce thermal stress. Based on the results of the thermal stress study using the finite element method, it has shown that the location of the thermal stress on the prototype brake shoe according to the location of the crack on the real brake shoe. The brake shoe's design which includes single notch in the center of brake shoe which is can help to reduce thermal stress. The results from this study should be validated with the results from the field test to evaluate both of thermal distribution and braking efficiency in term of braking distances as well.
