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

This research suggested natural hemp fiber-reinforced ropes (FRR) polymer usage to reinforce recycled aggregate square concrete columns that contain fired-clay solid brick aggregates in order to reduce the high costs associated with synthetic fiber-reinforced polymers (FRPs). A total of 24 square columns of concrete were fabricated to conduct this study. The samples were tested under a monotonic axial compression load. The variables of interest were the strength of unconfined concrete and the number of FRRlayers. According to the results, the strengthened specimens demonstrated an increased compressive strength and ductility. Notably, the specimens with the smallest unconfined strength demonstrated the largest improvement in compressive strength and ductility. Particularly, the compressive strength and strain were enhanced by up to 181% and 564%, respectively. In order to predict the ultimate confined compressive stress and strain, this study investigated a number of analytical stress–strain models. A comparison of experimental and theoretical findings deduced that only a limited number of strength models resulted in close predictions, whereas an even larger scatter was observed for strain prediction. Machine learning was employed by using neural networks to predict the compressive strength. A dataset comprising 142 specimens strengthened with hemp FRP was extracted from the literature. The neural network was trained on the extracted dataset, and its performance was evaluated for the experimental results of this study, which demonstrated a close agreement.

During this cooperative education program at the Bang Bo District Agricultural Office, Samut Prakan Province, a study was conducted on the costs and returns of rice cultivation using chemical inputs compared to using biopesticides in combination with chemical inputs among farmers in Bang Phli Noi Subdistrict, Bang Bo District, Samut Prakan Province.The objectives of this study were: To examine the costs and returns of rice cultivation using chemical inputs compared to using biopesticides in combination with chemical inputs among farmers in Bang Phli Noi Subdistrict, Bang Bo District, Samut Prakan Province. To explore the challenges of using biopesticides in rice cultivation among farmers in Bang Phli Noi Subdistrict, Bang Bo District, Samut Prakan Province. The study found that in the 2024/25 growing season, the total production cost for rice cultivation using biopesticides in combination with chemical inputs was 5,099.50 THB per rai, consisting of variable costs of 4,432.50 THB per rai and fixed costs of 667.00 THB per rai. Meanwhile, the total production cost for rice cultivation using only chemical inputs was 5,129.00 THB per rai, consisting of variable costs of 4,390.00 THB per rai and fixed costs of 739.00 THB per rai. The cost difference between the two methods was 114.50 THB per rai. Regarding the returns on rice cultivation in the 2024/25 growing season, the field using biopesticides in combination with chemical inputs yielded 1,000.00 kilograms per rai, with an average selling price of 8,500.00 THB per rai. Farmers earned a total revenue of 8,585.00 THB per rai and a profit of 3,485.50 THB per rai. On the other hand, the field using only chemical inputs yielded 1,000.00 kilograms per rai, with an average selling price of 8,500.00 THB per rai. Farmers earned a total revenue of 8,500.00 THB per rai and a profit of 3,371.00 THB per rai. The total income difference between the two cultivation methods was 114.50 THB per rai. In terms of challenges related to the procurement of biopesticides, it was found that biopesticides are difficult to obtain, with limited or no availability in certain areas. Additionally, relevant agencies do not provide continuous support for biopesticides, making this the most significant issue. Regarding the use of biopesticides, the most critical challenge is that once fresh biopesticides are mixed, they must be used immediately and cannot be stored, as their effectiveness deteriorates over time.
