Nowadays the fuel energy is consumed more than it was used in the past and most of energy used comes from petroleum which is not reuseable. Morever the crude oil which is raw material to be refmed is likely to take place in nature; it usually takes a long time. Therefore this natural resource must be used efficiently to maximize its benefits. Contructing Econo Power Car will be one ofmany methods to decrease the energy consumption. The Econo Power Car was designed to be water drop in order to reduce the wind resistance. The body was designed to cover all parts in order to decrease the circulation of air and the lightweight aluminium alloys were the materials to use. Besides the engine was improved to increase the complete combustion by adding 2 more spark plugs and an inlet valve rocker arm slide was installed to reduce the energy consumption ofthe engine while it was turn off. The test to fmd out the economy rate was done by collecting data based on the theory from the Automotive Engineering. The crucial factors affecting the economical fuel consumption was frictions which were friction of the road and friction of the air. Therefore the design to be water drop-shaped with closed cover was done to reduce friction and the wheels were adjusted everytime before competition. The results revealed that it archieves the goal. From the 7th Honda Econo Power it could save energy at the rate 543.018 km per litre at the speed 25 km per hours.

The purposes of the research were to create computer assisted instruction for Basic Engineering Training Subject (Unit 1-4) to find out the efficiency validation of computer assisted instruction based on the standard of 90/90 and to analyse the learning achievement of the students after using the computer assisted instruction. The subjects in the study were 17 first-year diploma engineering students enrolling at Rajamangala University of Technology Phra Nakhon. The researcher made the experiment by baving the students pretest. Then they studied by using the computer assisted instruction. After the students had posttest the efficiency of the computer assisted instruction was calculated as well as the leaming achievement was analysed. The research result revealed that the efficiency of the computer assisted instruction was at the standard of 90/90 Moreover the learning achievement after using the computer assisted instruction was different at the significant level of 0.05.

The objective of the study were to produce 5 prototype products made of native fabric Paihoochang Banglen district Nakhon Pathom Province which were facial tissue boxes hanging hand towels bolster cushions bags and tablecloths and to study the opinion’s customer toward prototype products about styles sizes utilizations and attractiveness on different products. Choosing by the random sampling there are 200 evaluators who were interested in prototype products. The prototypes products were presented in 4 department stores of Nakhon Pathom. The statistic analysis was done by using the computer program. The research found that the most of the evaluator were 31-40 years of age females single and graduated in Bachelor degree level. Their occupations were running private business with over 20001 baht income per month. The purpose for buying products was the presents or souvenirs. The motivation for buying products was the utilizations. The result of customer satisfaction affected phototype products from native fabric weaving showed that the average highest satisfaction in styles of product was the hanging hand towels A which was decorated by jacket style. The satisfaction of sizes of product showed the average highest was the hanging hand towels A which was decorated by jacket style and B which were decorated in scarf style. The satisfaction of utilizations of product showed the average highest was the hanging hand towels A which was decorated by jacket style. The satisfaction of attractiveness of product showed the average highest was the facial tissue boxes A which was decorated by jacket style. The 4 issues satisfaction of products found that all prototypes was the average high the hanging hand towels A which was decorated by jacket style was the average highest .

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to reading Micrometer 0.001 inch based standard 90/90 and analyse the leaning achievement of the student after by using computer assisted instruction The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90/90 Moreover after learning achieverment At significant level of 0.05

The aims of this study are to 1.) develop a new woven Mudmee pattern which inspired by optical art integrated with the silhouette of Prasat Si Khoraphum in Surin province 2.) use the developed Mudmee pattern to improve clothing design influenced from 1960s fashion 3.) test the satisfaction level of the finished Mudmee clothes from the sample group. There are 7 textiles professionals including pattern designers textile artists Mudmee textile specialists and 5 fashion designers as supervisors in screening the patterns and designs. The sample group is selected from the staffs who work in Rajaphat Surindra University and Rajamangala Northeast (Surin Campus). The tool in this research are the fabric pattern sketches inspired by optical art integrated with the silhouette of Prasat Si Khoraphum the 1960 fashion clothing design sketches and the satisfaction survey. The satistical package for the social science program was employed fro mean and percentage. This study found that the most selected designs from 7 textiles professionals were Pra Sart Moom Soong 1 pattern Nammatam1pattern and Rekhakanit 4 pattern. There were 9 jacket sketches that had been selected. The level of satisfaction on the clothing design from 1960 era of 213 women staff who work in Rajabhat Surindra University and Rajamangala Northeast University (Surin Campus) showed that the Pra Sart Moom Soong 1 pattern gained the highest level of satisfaction (4.78) The Rekhakanit 4 pattern was the most aesthetics pattern (4.70). Finally the sample group satisfied the color and pattern of Nammatam1 the most (4.73). In Chon-Phoa group the most aesthetic jacket patterns were Pra Sart Moom Soong 1 (4.67) and Nammatam1 (4.70). While the Rekhakanit 4 pattern appeared to has the highest level of correlation between pattern and clothing design (4.74). In the uniform group the most aesthetic 1960 jackets pattern were Pra Sart Moom Soong 1 (4.74) and Nammatam1 (4.71). While the Rekhakanit 4 pattern appeared to has the highest level of correlation between pattern and clothing design (4.73). In Art and Fashion group highest level of correlation between pattern and clothing designs for each pattern were Pra Sart Moom Soong 1 pattern(4.67) Rekhakanit 4 pattern (4.69) and Nammatam1 (4.70).
