The research is study motives the affect participation in quality assurance personal of Faculty of Engineering Rajamangala University of Technology Phra Nakhon from example group of 182 people which classified by sex ages position educational degree field of work and working life. This research is used themethod is collecting data by question tool themethod is questionare tool fo collected data that could be two categorized include knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of Faculty of Engineering Rajamangala University of Technology Phra Nakhon whom 63.70 persent classified by the educational field and 36.30% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects the result appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages educational degree field of work and working life in their readiness in entering Asean Community. position

The research project investigated the effects of CoO additive on dielectric ferroelectric physical and mechanical properties of modified Bi0.5(Na0.81K0.19)0.5TiO3 ceramics were investigated. The samples were synthesized by solid state reaction technique where powders were calcined at 850 °C for 4 h and ceramics were sintered at 1050 °C for 4 h which difference heating rate controlled i.e. 100 300 and 600 °C/h for. The ceramics of BNKT/x wt.% CoO was added CoO by various x=0.00 0.10 0.20 0.30 0.60 and 0.90. Phase formation was determined by X-ray diffraction technique (XRD). The X-ray diffraction analysis of the ceramics suggests that all samples exhibited a perovskite structure. The dielectric properties under room temperature and various temperatures were also determined. Dielectric measurement data showed that the additive and heating rate controlled influenced dielectric constant and dielectric loss. Furthermore the hysteresis loop behaviors slightly changed with increasing the CoO contents.

This research presents the engineering properties of asphalt (AC 60/70) modified with different ratios of scrap natural rubber. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 7% scrap natural rubber into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 7% scrap natural rubber. For asphaltic concrete Marshall Stability increased with adding scrap natural rubber into asphalt. Moreover the stiffness modulus of asphaltic concrete can be improved 13.53 compared to AC 60/70.

Nowadays a disc brake is one of important auto parts for motorbike cycle industry which effected directly to life safety. As the result this project aims to test the performance of the disc brake in order to study the physical disc brake that effects to braking distance and to be an alternative for testing the brake disc. Therefore the braking performance tester was designed and created in the single dynamometer which was not over 9.70•kgm2 as the moments of inertia of motorcycles. Regarding JASO T204:2001 this test was focused on the 3 different types of brake discs (i.e. normal type grooving type and perforated type). The tested temperature was at normal state of the brake disc temperature (60°C - 80 °C) and at high state (more than 100 °C). The braking force from 9.81N to 34.33N at master cylinder was tested. The result revealed that at normal temperature the braking performance of the three disc brakes (normal type grooving type and perforated type) was at 7.29 9.10 และ 9.50 m/sec2 per 1m2 of contact surface areas respectively. However the brake performance at high temperature was at 7.21 9.03 และ 9.46 m/sec2 per 1m2 of contact surface areas respectively. This result reveals that the most efficient disc brake at normal temperature was perforated type of disc brake which was 30.32% different from normal type of disc brake. Likewise; the perforated type of disc brake was the most performance disc brake at high temperature which was different from normal type of disc brake at 31.21%

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.
