Today educational institutions are awareness to using ICT-based educational management through online or e-learning. This learning method is a strategy to develop their organization to be a knowledge-based society. Rajamangala University of Technology Phra Nakhon (RMUTP) itself applies ICT-based educational management by improving fundamental structure of information technology and publicizing the policy on the ICT-based educational management to its personnel. The policy is to enhance a student-centered learning method with a practical integrated instruction. It promotes cooperation and networking of ICT instructors and encourages support and dependence between students and instructors. Moreover RMUTP establishes connections with other network to effectively use ICT-based learning with educational management.

The purposes of the research were to create and find efticiency validation of computer assisted instruction focused on the fundamental of welding for the standard 90/90 and analyze the students learning achievement after using computer assisted instruction. The samples were the 20 first year Bachelor of Engineering Program in Industrial Engineering Rajamangala University of Technology Phra Nakhon. The researcher experimented by using pretest and then using the computer assisted instruction focus on the fundamental ofwelding 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.

In general for the refrigeration the cooling coil is almost used to be the device to decrease the temperature. Thus in order to design heat exchange we should study the heat transfer into the cooling coil. This research proposes the numerical using finite element method for calculating the temperature at any position of the cooling point for considering to porous media. After that to create an algebraic equation fmite element for writing the program to search the solution by estimating the temperature. The research demonstrates that the changing of temperature will be decreased to saturated condition that is the temperature around the region of the cooling coil model edge will be decreased. The longer time the lower temperature around each position will decrease respectively until the temperature at each position inside the model are the same as region of the cooling coil model edge. Therefore this search result can be the basic for the comparison with the similar problem of other

Product development of End Mills AISI M42 tool steels products by cryogenics treatments after process by heating system through austenite structure had been conducted in order to increase effectiveness of wear resistance geometry designed in quenching figures quality of chip flow and improved by the cutting edge with sub-zero and heating system through producing the cutting tools on the rim of rake angle at 8° and 12° and 15° austenite temperature at 1210 ° C varied in room with temperatures at 35°C lower - 70 °C and -196°C respectively. The tempering at 535°C had been three time. End Mills figures then had been operated by 5 axis CNC grinding machine for the tools. The experiment had been conducted in accordance with the AISI 1045. Such as result revealed that stress relive of tools. it hardness between 67.7 up to 68.3 HRC and reduced I HRC. Having compared with the un-stress relief it revealed that on the 15° rake angle shear force increased 8° and 12° respectively. The result had denied the Shear theory however resisted against erosion better than 12° and 8°. The result revealed that cooling at - 196°C would help increase more 15% of cut effectiveness. Cooling treatment below 0° had tended to positively resist the erosion of the out tools. With its development of control of degrees of cooling substance acid the quality of products would be better increased. Such a result could be based of the development of product lines on highly-qualities cut tools which was domestically produced.

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
