This survey was conducted from 480 samples that were randomly conducted by typical sampling method. Data were collected by using Influence of Marketing sociological factors and attitudes have towards influencing the buying decision of Sufficiency Economic books. questionnaires. The result of this research found that: Marketing factors have effects upon buying decision of sufficiency economic books with factors such as product price place promotion have effect in decision making of buying sufficiency economic book at 0.05 significance level. Sociological factors also show influence in buying sufficiency economic books with attributes such as family values source of news social class and social values affecting decision of buying sufficiency economic books at significant level 0.05. Attitudes relative effects on buying sufficiency economic books decision making can be segregated into different interest groups. Only attitudes of the group who have heard or aware and the group of applied of concept of sufficiency economy philosophy have no effect on their buying decision. In the group who understand the philosophy attitudes shows no effect towards their buying decision. Lastly in the group who understand the philosophy the outcome shows no relevance on their buying decision. Highly educated group with post graduate studies attitudes have tendency to think that sufficiency economic philosophy tend constraint progress. The higher age group showed limited interest to sufficiency economic philosophy.

This research aims to study about the uses and gratifications of direct Marketing that being effect on purchasing decision process for population in Bangkok area.In order to learn more about the relationship of demographic data per the approach to direct advertising .The uses and gratifications and purchasing decision process of consumer in Bangkok areaits sample are drawn from Bangkok population for 400 samplings. The outcomes are as: 1.The use and gratification of direct marketing from direct-mail and television per purchasing process upon consumer are moderate. 2.Grnderthe difference in gender has approach to direct advertising differences. 3.The difference in level of education bas difference effects upon the uses and gratifications of its direct advertising 4.Various demographic in Bangkok area has difference purchasing decision pricess. 5.The approach to direct advertising has no relationship to the uses and gratifications. 6.The uses and gratification upon the direct advertising

This research presented the details of design and constructions of tesla transformer for testing insulator. The out put of the tesla transformer has a rate of 120 kV and 120 kHz. Tesla transformer consisted of primary coil and secondary coil which is wound on a PVC insulating chamber and use air insulation in part of coaxial. The Rotary Gap is rotated eletrode which use for increasing efficiency of voltage generation. This paper presented the details of design and constructions are explained. And compare the tesla Transformer reproduce which is created the voltage at 120 kV and frequency 120 kHz for used in HighVoltage Laboratory Faculty of Engineering Rajamangala University of Technology Para Nakhon.

The purposes of the research were to create and efficiency validation of computer assisted instruction focused on the practice to CNC Tuming of the standard 90 / 90 and analyse the student leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 23 first year diploma students enrolled in Computer Numerical Control Rajamangala of Technology. North Bangkok Campus. 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 CNC 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 0.01 .

The purposes of the research were to create computer assisted instruction for Basic Engineering Training Subject (Unit 1-4) to find out the efficiency validation of computer assisted instruction based on the standard of 90/90 and to analyse the learning achievement of the students after using the computer assisted instruction. The subjects in the study were 17 first-year diploma engineering students enrolling at Rajamangala University of Technology Phra Nakhon. The researcher made the experiment by baving the students pretest. Then they studied by using the computer assisted instruction. After the students had posttest the efficiency of the computer assisted instruction was calculated as well as the leaming 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.
