The objective of research was to study and analysis the Electric vehicle structure of Rajamangala University of Technology Phra Nakhon. The Electric vehicle designed to save energy protect environment and cognitive development of student by used the computer software help in the design Material selection Finite Element Analysis Appropriability of the Electric Vehicle Structure and di s p l a c e m e n t of the vehicle structure by using the computer program help in the calculation for the Finite Element Method including to the development of engineering skill. The research must to create the Electric vehicle prototype to suitable and the structure have lightweight and strong for the electric vehicle and focuses on energy efficiency and the material of structure used steel pipe. This research can use to other working structure and future vehicle in sustainable. The vehicle has two seats Capable of running speed to 0-80 km/h the weight at the vehicle structure not over 1 0 0 kg. And the material of structure used steel pipe. This researching can use to other working structure and future vehicle in the sustainable.

Freight is major source of income of the State Railway of Thailand (SRT); which had revenues of one billion baht a year. The development of freight by rail system to be fart punctual and safe is important. Knuckle pin serves tension and shear stress in pulling Rolling Stock. Strength testing of Knuckle pin must be done by technical and engineering knowledge. SRT has 6000 Rolling Stocks; that means 6000 Knuckle Pin has been used and it is likely to increase due to the construction of the Double Track Project and the purchase of new Rolling Stocks. The efficient Knuckle Pin prolongs lifespan and SRT would have benefit on saving cost of maintenance and increase safety in the transportation of goods. This research is aimed at creating the understanding about the quality of the Knuckle Pin modeled Nat Mall. The pin would be test by Standard Test Methods for Tension Testing of Metallic Materialsand the Standard Test Method for Analysis of Carbon and Low-Alloy Steel by Spark Atomic Emission Spectrometry and Hardness Testing Machine and Microstructureto determine the cause of pin’s damage. This study will contribute the standardization of the quality of the Knuckle Pin which is used in Rolling Stocks of SRT.

The purposes of the research were 1) to study the personal factors of the RMUTP undergraduate; 2) students of examine the opinions of the students participating in the activities; and 3) to compare levels of students’ opinions on activities porticipation according to their personal factors. The samples were 400 undergraduate students of Rajamangala University of Technology Phra Nakhon chosen by using proportional stratified sampling. The research instrument used to collect data was the questionnaire. The data were analyzed by t-test and F-test to compare the percentage mean value and the standard deviation. The level of statistical significance was at .05 level and multiple comparison test was run by Scheffe. application. . The result of research found that the majority of students were male (54.8%) the students were studying in the first year (29.3%) Bangkok commercial campus (47%) the students whose parents were together (72.3%) the students whose families had more than 4 members (68.25%) the students whose total family incomes (baht/month) 30000-39999 baht (22.3%) the students lived in their house/relatives house (3.98%) by the highest average side was benefit that received from attending the activities (3.98%) an opinion of students about attending the activities held by RMUTP have the overall level in high (3.67%) The hypothesis testing revealed that Rajamangala University of Technology Phra Nakhon students’ opinions had significant difference at .05 level in terms of their academic year and faculty.

This research has been aimed to study learning organization levels on five learning disciplines at Rajamangala University of Technology Phra Nakhon and individuals factors affecting the five learning disciplines. the samples were 400 Rajamangala University of Technology Phra Nakhon lectures and staff selected by stratified random sampling. Questionnaires were administered to collect data which were statistically analyzed and compared using the percentage standard deviation and hypothesis testing by t-test and One-Way ANOVA. the statistical significance level was set at the 0.05 The result of the study indicated that the level of the learning organization (five learning disciplines) of Rajamangala University of Technology Phra Nakhon (RMUTP) in the overall as well as the individual aspect was high. the highest aspect was mental models followed by systems thinking and team learning respectively. the hypothesis testing revealed that the personnel working at the organization with different educational levels positions and work tenure did not differ at the significance level of 0.05 in terma of RMUTP learning organiattion (five learning disciplines) Conclusinos from the hypothesis testing yielded that personal factors including work units deucational levels positions and work tenure rejected every hypothesis due to the fact that RMUTP employees no matter differences in terms of work units educational levels job titles or duration of operation were always active to improve their work ability. The research results also suggested that RMUTP personnel always kept on learning improving themselves and tracking down the information and knowledge. they were also able to transfer that through information technology stystem which could be accessed easily via various channels. strong teamwork was also an organizational culture. executives vision had been transferred to the staff members which could be seen form the overall highly-ranked results in every aspect. they commented that the knowledge management center was effective. moreover.every work unit had organized its own work content and stored it on the websites to be easily accessible for other involving units. the universith encouraged the staff by giving rewards to any outstanding units for their best practices as this could signify as a model for other units to apply the knowledge in their respective departments for achieving continuously sustainable learning organization in the future.

This study aims to study the buying habits of tomato juice with students to study. Mixture Marketing Influencing consumer behavior to buy tomato juice of bachelor’s degree. To determine the relationship between the individual factors on the consumer behavior to buy tomato juice of bachelor’sdegree. And to compare the marketing mix Factors Influencing consumer behavior to buy tomato juice of bachelor’s degree 4 year coures faculty of home economics Technology Rajamangala University of Technology Phra Nakhon. By personal factors The sample of students 316 person The instrument was a questionnaire The statistics include freq percentage The mean standard deviation cost t-test F-test and Chi - Square (.𝑥2) The study indicated that Most consumers were female. 21 years The Year 4 Department of Food and Nutrition The average income per month. THB 5001-8000 Consumer behavior is found The most commonly purchased brand Doi Kham.
