The purposes of the research were to create computer assisted intruction for Manufacturing process subject to find out the efficency validtion of computer assisted instruction based on the standard of 90/90 and to analyse the students learning achievament after using the computer assisted instrucion. The subjects the study were 17 first-year diploma enploma engineering students enrollong at Rajamangala University of Technology Phra Nakhon. The researcher made the experiment by having the students pretest. The they studied by using the computer assisted instruction foused on practiocing basic turning. After the students had studied and had posttest the efficency of the computer assisted instruction was calculated as well as leaning achievement was analysed. The research resilt revealed that the efficiency of the computer assisted instruction was at the standard of 90/90. Morever the learning achivement after using the computer assisted instruction was different at the singificant lavel of 0.05

The purposes of the research were to create computer assisted instruction for Electric Power System Analysis Chapter 1-2 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 third-year diploma engineering students enrolling at Rajamangala University of Technology Phra 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.

Probiotic is a micro organism that is useful for human bodies and can help creating balances for human intestinal system. The objective of this research is to compare amounts of fat substitutes supplied in the industries in order to determine their ability to encapsulate Probiotic microbes in the production of yoghurt ice cream to ensure maximum survived Probiotic microbes. In this research two fat substitutes Purity SM 100 and CRYSTAL texTM 648 were used to substitute skim milk in the standard formulas in order to study numbers of survived Probiotic microbes and to test the sensory acceptance. For the sensory acceptance it was found that the Probiotic yoghurt ice cream containing 20% Purity SM100 is acceptable at the maximum significance (p ≤ 0.05) because its flavor and taste was better than other samples as well as the best overrun with statistical significant differences (p ≤ 0.05). However by addition of both fat substitutes at different concentrations pH values of Probiotic yoghurt ice cream products did not have statistical significant differences (p ≥ 0.05). When Lactobacilluss acidophilus Bifidobacterium and Streptococcus thermophilus microbial starters were added into the Probiotic yoghurt ice cream using both fat substitutes in place of skim milk at ratios of 10% 15% and 20% respectively under a storage condition of -20oC for 4 weeks it was found that types and amounts of fat substitutes affected the surviving rate of Probiotic microbes in the product with a statistical significance (p ≤ 0.05). The addition of fat substitutes Purity SM100 and CRYSTAL texTM 648 at all concentration levels made Probiotic microbes survive in the product which illustrated that both fat substitutes used in above experiments could encapsulate Probiotic microbe cells. The survived Probiotic microbes were in the range of 108 – 109 CFU/ml in comparison to the Probiotic yoghurt ice cream with the standard formula without the addition of fat substitutes that has survived Probiotic microbes of only 106 CFU/ml.

The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir rice straw and husk as a major ingredient in concrete to replacing usual stone dust the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin coir rice straw and husk by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg. water absorption at 7.96% and compressive strength at 65.4 ksc. Moreover these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.

The purpose of this quasi-experimental research was to study the effect of an English camping program based on Cognitive Behavioral Theory on students self-efficacy in using the language for communication. The population of the study 118 first-year students of the faculty . of Liberal Arts Rajamangala University of Technology Phra Nakhon in the academic year 2009 were divided by using simple random sampling into 3 groups: experimental· group 1 whose members were assigned to participate in the English camping program based on Cognitive Behavioral Theory; experimental group 2 of which the members were given the infonnation on Cognitive Behavioral Theory and how to develop self-efficacy in using English for communication to read ; and the control group. The instruments used were a questionnaire a self-assessment questionnaire on self-efficacy developed by the researchers and Before & After reviews The statistics used were percentage and t-test. The results were as follows: 1. The level of self-efficacy in using English for communication after the groups participation in the English camping program based on Cognitive Behavioral Theory was significantly higher at the level of 0.05 which was not significantly different at the follow -up. 2. The self-efficacy level after participation in the English camping program was significantly higher at the level of 0.05 than that of the experimental group 2 after being assigned to read. 3. The level of self-efficacy after participation in the program was statistically higher than that of the control group at the level of 0.05. 4. The qualitative data collected from the group participating in the program indicated an improvement in the level of self-efficacy in using English for communication.
