The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to basic file based standard 90/90 and analysis the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year bachelors degree 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 Orthographic Drawing for First Angle Projection and Third Angle Projection. 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 analysis 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 achievement At significant level of 0.05

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to reading vernier caliper 0.02 m.m. and 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 achievement At significant level of 0.05

The purposes of the research were to construct and to evaluate the efficiency of computer- assisted instruction program for reading vernier caliper and micrometer based on criteria and analyze the learning achievement of the student after using computer - assisted instruction. The samples were the first year undergraduate 17 subjects students at Rajamangala University of Technology Phra Nakhon in 2006 participated in this study. The experiment was conducted by using pretest post test design. The efficiency of the computer - assisted instruction was calculated and was the learning achievement of students after studying analyzed. The result revealed that the efficiency of the computer - assisted instruction was efficient in criteria and learning achievement significantly increased at .05 level.

This research was aimed to analyze work performance classified by personal information to investigate internal factors of support personnel work performance and influence of internal factors affecting work performance of the support personnel at Rajamangala University of Technology Phra Nakhon. The population used in this study was 693 staff working at Rajamangala University of Technology Phra Nakhon Bangkok. The sample size was determined by Craig and Morgan method to draw out 250 samples. The research instrument was a questionnaire constructed by the researcher to collect data manually. The data obtained from the questionnaire were analyzed using percentage mean standard deviation and T-test F-test ANOVA Pearson coefficient and multiple regression analysis. The research revealed the results as follows. Work performance of the support personnel of Rajamangala University of Technology Phra Nakhon in the overall was at high level with the mean Organization factors of the support personnel of Rajamangala University of Technology Phra Nakhon in the overall was at high level with the The results of the study on personal factors agreed with the overall performance of Rajamangala University of Technology Phra Nakhon personnel. It was found that the status salary and educationhours and working centers were significantly different .
