การศึกษาส่วนผสมที่เหมาะสมของโครงสร้างกันแรงกระแทกของรถยนต์จากกากผักตบชวาและแกลบสำหรับการชนคนเดินเท้า
Recently the Thai industry has continually grown up and also plays a role to economic growth in the country which affects the many of automotive components to be in the market. While the degeneration and waste of automotive components had increased as well. Therefore a crash box is one of the automotive parts which damage from the accident. Consequently the researchers have created a prototype material to develop into the crash box to reduce the environment problem from automotive parts. The random mixture of water hyacinth and husk was attempted to up to 5 ingredients. By forming a solid cylinder and 200 mm of long was used as prototype of the crash box in this research. Thus the energy absorption using compressing test was attempted to by the universal testing machine. The results showed that using polymers as a binder with 50% of water hyacinth and 50% of husk was the better ability of energy absorption. Regarding this ingredient 1612444 J/m3 of the energy absorption was referred to indicate that is the best ability of energy absorption. It is probably reduce the severity of the impact in the event of pedestrian collision.

The objectives this special project were to produce the Chao Phraya Cruise 3D Motion Graphic media and to study about the satisfaction of the audiences who watched Chao Phraya Cruise 3D Motion Graphic which the target was 100 of foreign tourists and Thai Tourists. Under this study the statistics used for analyzing the data were frequency percentage average and standard deviation. The study indicated that the samples were satisfied with the Chao Phraya Cruise 3D Motion Graphic about content was at a high level (= 4.41 S.D.= 0.66) and about quality was at the highest level (= 4.63 S.D.= 0.58)

The propose of this research present a comparative study of the Reliability Improvement of Electrical System for Electric Mass Rapid Transit Train which describes in term of the power supply efficiency including voltage imbalance that could indicate how much the electric power quality is being more or less. The electrical system to be used in the Mass Rapid Transit system has 4 types of connection between three (3) phases of Metropolitan Electricity Authority (MEA) transformer and station transformer which is Single phase V-Type Scott and Le- Blanc to be considered for the different transformer connections type could be carried out and resulted in the most unbalanced in power supply as well as properly solution for power supply mitigation of voltage imbalance. From foregoing the data analyst was discovered that a single phase connection could cause the most unbalance voltage but on the other hand Le-Blanc connection is the least unbalance which could be reduced the impact on the Mass Transit Train and increase the credibility of consumers in order to continuity implement service usage.

Recently the consumption rate of vehicle is continuously an increase as an economic growth. This not only causes the massive traffic but also effects on the accidental capacity especially the road accident between car and pedestrian. The most of victims who dead are Vulnerable Road Users are crashed by the front-end structure. Regarding this problem; the possibility of the Pedestrian Crash Simulator has studied and established following the Euro New Car Assessment Programs in Pedestrian Protection. This simulator can be adjusted in 3 axles of tested position. Besides the body forms are used as impactors which are pushed the high speed drive unit via the iron less linear motor. In addition the simulator can be adjusted from 0 to 65 of degree comparing the horizontal line. As a result the limitation of the Pedestrian Crashed Simulator is linear speeds because of budget limitation. The highest of performance is not more than 3000 mm/s with 19.46 mm/s2 of speeds and acceleration respectively. However this simulator can be developed the ability by addition of the power unit and control equipment. The highest acceleration should be 35.06 m/s2 within 1.76 m. of magnetic track rail to equivalent the specified condition of the EURO NCAP (in Pedestrian protection).

The objectives of this special project were to produce media infographic for anti-HIV drugs and evaluate satisfaction towards anti-HIV drugs. The data collected100 person from usersof anonymous clinicthe Thai Red Cross AIDS Research Centre who was age between 20-50 years. The statistics to analyze the data included frequency percentage average and standard deviation. The study found that satisfaction with mediafor anti-HIV drugs was at high levels (𝑥 =4.47 S.D.=0.76).
