The purposes of the research were to create computer assisted instruction for Mechanics of Materials Subject to find out the efficiency validation of computer assisted instruction based on the standard of 90/90 and to analyse the students learning achievement after using the computer assisted instruction. The subjects in the study were 17 second -year diploma engineering students enrolling at Rajamangala University of TechnologyPhra Nakhon. The researcher made the experiment by having the students pretest. Then they studied by using the computer assisted instruction focused on practicing basic turning. After the students had studied and had posttest. the efficiency of the computer assisted instruction was calculated as well as the learning 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 aimed of this study are to 1) Pattern design development of silk loincloth (hangkrarok silk) of Community Silk-Weavers Groups in Huairat district Buriram province. 2) The study of customer satisfaction of developed silk loincloth (hangkrarok silk) by Community Silk Weavers Groups in Huairat district Buriram Buriram province. The procedure of this research is population of Community Silk-Weavers Groups in Huairat district Buriram province. All population is 8 (Tam-bon) districts. In pattern design development processing it used pattern design of silk loincloth (hangkrarok silk) by 18 patterns design sketching as instrument and selected 9 patterns design sketching by 5 specialists. For corresponded with colors using of silk yarn and to combine twist silk yarn pattern design development with weaving technique apply and pattern design development with applying of structure weaving. In order to taking sketch to weaving by the random sampling from population is Community Silk- Weavers Groups in Huairat district Buriram province.The random sampling is 1 group. The weaving proceed had to progress to get the pattern design specialist selected; there are 9 patterns. In conclusion of this research 9 patterns design selected and progressed with the development step and get the products of silk loincloth (hangkrarok silk) as follow the 9 patterns design selected was 100 percent. And then the researcher process in next step was taking developed silk loincloth (hangkrarok silk) for studying the satisfaction of silk loincloth (hangkrarok silk) of Community Silk-Weavers Groups in Huairat district Buriram province. by taking a random purposive sampling there are 320 samples. To study in 3 parts as follow 1) colors 2) patterns and 3) the structure of patterns design developed silk loincloth (hangkrarok silk). The result of this research is the customers had the satisfaction in the parts of colors pattern and the structure of patterns design developed silk loincloth (hangkrarok silk) in high level. Thus the researcher recommended that having the afterward researching for the sustainable silk textile development.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the information retrieval practice to record data for report writing for the standard 80 / 80 and analyze the student learning achievement after using computer assisted instruction. The samples were the 23 Diploma students enrolled in Rajamangala University of Technology Phra Nakhon North Bangkok Campus. The Researcher experimented by using pretest and then using the computer assisted instruction focus on the practice to prepare specimens in learning next the students did the posttest . After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 80 / 80. And after studying by using computer assisted instruction. the students learning achievement increased significantly at 0.05.

The purpose of this research was for studied of The Development of Indian Women dresses of Punjabi style made by weaving cotton fabric from the North-eastern part of Thailand. These Studied are explored the satisfaction to the development of Indian Women dresses of Punjabi style made by weaving cotton fabric from the North-eastern part of Thailand. This research was Quasi-Experimental Research Selected among of 250 people sampling groups were Indian women or Thai women with Indian nationality who live in Bangkok by Accidental Sampling and analysis the information by SPSS computer program by a method of frequency percentage mean standard deviation and tCtest. The research result founded that the sampling group of people were married and under 30 years old who educated undergraduate degree or equal level. They were house wives with made and income 15001- 20000 per month. Their reason is appropriate and could wore them into the social occasions many else though. The results obtaining from studying the satisfaction in development of Indian womenns dresses of Punjabi style by using the hand C woven cotton fabrics from the north C eastern part of Thailand of types touching surfaces colors patterns/stripes. The total Mean as compared with the satisfaction of dresses was found as follow : Hong stripes Knid cotton fabrics had mean and its highest satisfaction being at a high level and as compared with the common data of such ; age education occupation income the satisfaction of Indian Women dresses of Punjabi style made by weaving cotton fabric from the North-eastern part of Thailand such as the touching surfaces colors the different at .05 statistics level. The another satisfaction the common data of such ; age education occupation income the satisfaction of Indian Women dresses of Punjabi style made by weaving cotton fabric from the North-eastern part of Thailand such as the touching surfaces colors the different at did not different at .05 statistics level. The satisfaction is not different patterns/stripes of fabrics but age education occupation income is different.

This research report of the Aluminum Can Recycle Machine Project is contrived the experiments at Rajamangala University of Technology Phra Nakhon by the hydraulic pressure. Nowadays the cans make by luminum material very useful in several liquid packaging industries. When people consumed the liquid inside the cans then the cans are worthless. But the cans can be recycling from the waste material. Although we have to reduce the waste materials to follow our world as improvement. From the reasons that we mentioned we decided to start the Aluminum Can Recycle Machine research project to keep him or her eager to put the cans to the machine for consumer then encourage them by giving something back such as a candy or a rubber etc. The system working by a PLC it controls the hydraulic pressure receives the sensor signals and displays status via the 7-segment panel. The machine accepts the standard beer can and the soda can for 10 cans a time in a slot when consumer put the cans into the can receiver block the machine gives a candy back to a consumer. After a receiver-block has the 40 cans inside the machine pressing the cans at once then releasing it to collector block.
