ออกแบบและสร้างหุ่นทดสอบการชนของรถจักรยานยนต์ภายใต้สัดส่วนโครงสร้างของคนไทย
The aim of this research is to design a prototype of a male dummy chest for motorcycle crash tests. The primary criteria discussed in this study are based on the unique features of Thai ergonomic body sizes with an age range of the highest fatal rate and the fundamental design of the Hybrid III 50th percentile male crash test dummy. A comprehensive experimental study of crash behavior of the prototype undergoing axial compressive loading is performed using the mutual procedure of cadaveric chest testing. For design criteria the largest chest deflection of 80 mm the maximum acceleration of 38.47g and the absorbed energy of 178.369 Joules are considered in the experiment. The obtained results show a good agreement with the experimental data of other researches in which the capability of the energy absorption depends on impact velocities. In addition the energy absorption capability of this prototype can accurately assess an injury level under AIS 3+. For this reason the first prototype of a male chest dummy is particularly suitable for an assessment of a lower serious injury level in a motorcycle crash test.
การเฝ้าระวังการเกิดไฟไหม้ในพื้นที่บ่อขยะโดยใช้โดรนและเทคโนโลยีการรับรู้ระยะไกล
This research was the application of Unmanned Arial Vehicle (drones) in conjunction with remote sensing technology to monitor the occurrence of the waste dump site fire. The research began with designing and developing prototype tools to collect data from the field site. After the tools were tested they were used to measure gases from the dumping sites. After that the field observation was performed in Nonthaburi Province Pathum Thani Province and Pha Nakhon Si Ayuthaya Province. The final step of the research was to collect the data of active fire hot spot and image from MODIS system satellite covered the area of Nonthaburi Province Pathum Thani Province Pha Nakhon Si Ayuthaya Province and Samut Prakan Province in the period of 1 November 2017 to 31 October 2018. The result showed that the developed drone and the prototype gas detection units worked as designed. The result of gases measurement by the tools were similar to the references equipment. The field observation showed that the dumping site mainly composted of plastic organic matter and cotton which up to 74.9 percent in total. This indicated the factor that influenced the dump site gas generation. Based on the combination technique in the research it could be concluded that Drone and Remote sensing technology were the compromised technology for monitoring fire from the municipal solid waste dump site area.
การพัฒนาสื่อมัลติมีเดียประกอบการสอนรายวิชา ง30275 งานจัดดอกไม้เชิงพาณิชย์ หน่วยที่ 6 เรื่องการจัดดอกไม้เบื้องต้นสำหรับนักเรียนระดับชั้นมัธยมศึกษาตอนปลายโรงเรียนไชยฉิมพลีวิทยาคม จังหวัดกรุงเทพมหานคร
The purposes of this study aim 1) to evaluate the academic achievement and 2) to study learners satisfaction towards teaching multimedia in the Course Ngor30275 Commercial Flower Arrangement Unit 6 Introduction to Flower for high-school students of Chaichimplee Wittayakom School Bangkok. Sample in this study is 30 students who attended Sports and Home Economics Program and chose Home Economics Course in to 2nd semester of the academic year 2019. According to studies 1) the result of the teaching multimedia proficiency assessment on the content basis by 3 experts was at the highest level by all accounts and the mean was equivalent to (X̅ =4.73S.D. = .31). And the result on the multimedia basis was also at the highest level and the mean was equivalent to (X̅ = 4.63 S.D. = .29) . 2 ) the assessment in the performance of a representative sample of students in the 8 different patterns using scoring rubrics whose standards were at every high level. 3) the assessment on the student’s satisfaction with the teaching multimedia for 8 patterns were as follow Pattern #1 - Spherical Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.61 S.D. = .06) . Pattern #2 - Equilateral Triangle Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.72 S.D. = .05). Pattern #3 - Scalene Triangle Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.61 S.D. = .03). Pattern #4 - Tall Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.68 S.D. = .06). Pattern #5 - Short Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.64 S.D. = .06). Pattern #6 - Long-Bouquet Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.66S.D. = .05). Pattern #7 - Circular-Bouquet Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.69 S.D. = .05). Pattern #8 - Flower Arrangement Pattern the overall satisfaction analysis result was at the highest level and the mean was equivalent to (X̅ = 4.72 S.D. = .08).
การศึกษาและพัฒนาโคมไฟตั้งพื้นจากผ้าย้อมครามสำหรับที่พักอาศัยคอนโดมิเนียม
The purpose of this project were to study floor lamp from indigo dyed fabric process of condominium. The researcher were interested in floor lamp from indigo dyed fabric product that could be used practically and beautiful. It were inspired by the mangrove tree root that grew out of the trunk to adhere. It made the mangrove tree root shape look like legs outstretched to suit for making it. The result of the floor lamp from indigo dyed fabric design were the shape obtained from the root of the mangrove to make the floor lamp from indigo dyed fabric design for use. It found that the floor lamp indigo dyed fabric could be used in residential condominium as well. There was a light that was not too dull or translucent when the light turned off. It would be beautiful when turned on to make the color and pattern more sharply.

This project was to design and development of indigo dyeing bag for men. The objective were to study the pattern and type of bag in order to get a new one and allow consumers to choose more that it were a folk wisdom that had a long time. There was an own identity and the villagers occupation. Setting it inspired in the pattern design from the overlapping curves of mountains. The color tones used in the set of indigo dyed bag design were to use cool tones. The materials used to make the bag consist of indigo dyed fabric genuine bull leather zipper mesh fabric adhesive fabric elastic magnetic button lining and pincer string bag lock. The bag strap used nylon string fabric to strength. The opinion assessment to the backpacks chest bag waist bag and belt bag from the indigo dyed fabric in Sakon Nakhon province. The sample group responded the following questionnaire: Bringing the indigo fabric to make the suitable product was the most 59 percent. The suitable materials were the most 42 percent. The suitable product shape was the most 55 percent. The suitable colors were the most 64 percent. The durability usage was the most 52 percent
