The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to cutting sheet metals 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

This research is an exploring research to be connected with the main purpose of learning about the satisfactions in working as other sides for supporting personal consists of supporting for government officers supporting for government staffs university staffs permanent employees and temporary employees in total 635 people. There are only 360 people of samples from the total as mentioned to be analyzed the factors and other satisfactions the result of this research is the level of surrounding factors in working as showing the average rate for all over as the normal level. In comparing with the personal factor and satisfaction were found that Male are much more than Female about satisfaction in all factors mentioned. And also single government staff there is most of satisfying than married and divorced status. Additionally the level of satisfaction will be reduced respectively as referring with ages type of working opportunity colleague and facilities but the satisfaction of reward will be much more which is depended on ages. Moreover the experienced staff will be much satisfied as follows: Type of working Reward Opportunity and Facilities but another side to be less satisfied are Colleague. However the responsibility of members in their family will be less satisfied almost all sides. Another thing the position is the most of satisfying colleague & facilities are next and reward & opportunity to be promoted as the last one. Moreover chief executive position satisfies more than head of department and operation respectively. Noise temperature dust smell air flow and colleague are the surrounding factors to be reflected with the satisfactions.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the records management for the standard 90 / 90 and analyze the student learning achievement after using computer assisted instruction. The samples were the 18 Bachelor of Business Administration Program in Management Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the practiced to prepare office equipment in learning next the students did the posttest. After that the researcher calculated to find the computer assisted instruction efficiency and analyzed the students learning 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 the students learning achievement increased significantly at 0.05.
