The purposes of this research were 1.) to study of expectation and reality for Development of research on Academic Staffs of RMUTP 2.) to study of needs assessment for Development of research on Academic Staffs of RMUTP. The sample is Academic Staffs of RMUTP from 9 faculty 343 Academic Staffs. The data were analyzed through percentage (%) mean (x̄) standard deviation (S.D) t-test modified priority needs index: PNI modified and content analysis.The results demonstrated that : Current conditions and expectations regarding the development and research of academic staff found current weather conditions are on average lower than expected nearly all sides. Considering the sort of requirements necessary for the development of research staff academic overview. The PNIModified between 0.04 -0.22 and found to have the highest PNIModified is The development of self-education and self-improvement with training / seminars (0.22) for a final order management (0.04).

The purposes of this research were to development of full-text research database for Rajamangala University of Technology Phra Nakhon and valuate the efficiency of the database system of full-text research database for Rajamangala University of Technology Phra Nakhon. The sample was academic staffs of RMUTP 35 academic staffs. Research design was a research and development follow these steps : study and analyze problems system design development system trial and evaluation of user satisfaction. For the study satisfaction using the evaluation form. The statistics used for data analysis were mean (𝑥̅) and standard deviation (S.D) The results demonstrated that : 1. Development of Full-Text Research Database for Rajamangala University of Technology Phra Nakhon by using database management software MySQL (MySQL) and PHP (PHP). The database developed has the ability to save edit delete and query. 2. Database System of Full-Text Research Database for Rajamangala University of Technology Phra Nakhon performance was good and the mean was 4.22 and the standard deviation was 0.19.

The purpose of this research was to 1) study the students leisure time. 2) study the learning patterns of the students of the Faculty of Industrial Education. And 3) find out the relationship between leisure time and learning styles of the students of the Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon. The samples of this research were Faculty of Industrial Education 245 students Rajamangala University of Technology Phra Nakhon were sampled stratified by stratified random sampling. Tools used in this research were questionnaire about the leisure time habits and the learning patterns of the students. The results of the research were; firsty the study of students leisure time behavior. Rajamangala University of Technology Phra Nakhon showed that the leisure time of students The overall score was moderate.The students leisure time is the interaction activity followed by the leisure activity. Learning Activities and health activities. Secondly results of learning models showed that learning styles of students of Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon At the mean level. it was found that there were 6 mean scores in the mean. The first was the collaborative learning model. Independent competitive and avoided. Finally Results of the relationship between leisure time and learning styles of students in Faculty of Industrial Education found that the behavior of leisure time in learning activities. Leisure activities There was a statistically significant positive correlation between the learning activities and the six learning styles at the .05 and .0.01 levels. There are positive relationships only with participatory learning models. At the .01 level of significance.

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%
