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 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 uSll1g the experiment by let the students do until test before class and then study by using computer assisted instruction focused on Section Views for Full Section and Half Section. 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 achievemenl al significant level of 0.05 .

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the practice to record data for report writing for t Ie standard 90/90 and analyze the student learning achievement after using (computer assisted instruction. The I samples were the 20 first year Bachelor of Science in Technical Education st~dents enrolled in Industrial Engineering Rajamangala University of Technology fhra Nakhon North Bangkok Campus. The Researcher experimented by using prete~t and then using the computer assisted instruction focus on the practice to Iprepare specimens in learning next the students did the posttest. After that the resrarcher 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 90 / 90. And after studying by using computer assisted instruction tme students learning achievement increased significantly at 0.05.

Corporate governance principle has played an important role in predicting the business failure because the concept of good corporate governance will result in value and value added to the business and shareholders. Several previous studies attempt to find the relationship between corporate governance mechanisms and firm’s performance. It was expected that company with good performance will not be likely to go bankrupt. However this article reviews the compiled documents and studies in the past concerning corporate governance mechanisms (board structure board committees and ownership) as application tool to predict business failures.

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
