Distribution trend of transient temperature profile of copper heat pipe from the start-up of outer wall temperature of evaporator section until the temperature was steady was studied. A two-dimensional model used numerical solution which based on finite difference method. The transient temperature distributions measured in all 3 heat pipe sections were compared with results from the numerical solution of the two-dimensional model that utilized the concept of temperature distribution in the pipe wall during transient operation. Results showed that the experimental trend and the theoretically predicted temperature profiles were similar. Moreover there was good agreement when compared with the numerical simulation of Mistry et al. (2010). Therefore the numerical-validated heat pipe temperature distributions were successfully simulated in a two-dimensional model.

The purpose of this research was to construct the efficiency of the Computer Assisted Instruction Package for Computer Instructional Package for Drawing 2 Dimension Subject for students in Vocational Certificate Education Level using subject by evaluating the efficiency of the Computer Assisted Instruction Package of the Students to the Computer Assisted Instruction Package for Drawing 2 Dimension Subject with the tools. The sample group was 30 students of Machine Shop Department in Vocational Certificate Education Level Pathumtani Technical College. Analysis by Index of Consistency Level of Difficulty Discrimination Power Average and Computer program. The result of this research was the efficiency 81.14/82.50 higher than the rule of 80/80. This could be concluded that the computer self study packagefor Drawing 2 Dimension Subject using can be used as a learning package efficiently.

The purpose of this research was to study and compare the reliability of Allen’s method (ΩW) and McDonald’s method (ωMD) using a NEO Five – Factor Inventory Scale and three different extractions with three different sample sizes. The sample was freshmen of Rajamangala University of Technology in Bangkok area. The results of the research were as the reliability of multidimensional scale from different extractions within the different sample sizes when using ΩW and ωMD were different with statistical significance at the level of .05. The estimation of reliability of multidimensional scale was most appropriate when using 3000 pseudo populations as the representative of large sample. The extraction of generalized least squares or principal factors with ΩW should be used with the sample sizes of 100 and 200 while the extraction of principal factors with ΩW should be used with the sample size of 500.

The research titled “Studying of social network usage behavior by university lecturers in Bangkok for teaching 3D computer subjects” aims to find out how useful social network is to the teaching of 3D computer subjects as well as the criteria for social network usage. These findings will be used to develop guidelines for redesigning to enable lectures to utilize social network effectively and high level education teaching allow the improvement of teaching quality.

This paper presents a remote control device adapted to control the power station equipment. This system is a part of the control and collecting data system. It is used to control the operation of the circuit breaker in the power station and to reduce the transfer of load quickly and easily. It is tested with an open - closed circuit of the power system control centers 10 of which have no error (100 percent) As for the amount of electricity It is tested by the meter reading of this controller compared to the actual payment system to a percentage error. It was found that the reading of zero percent power control error was less than the percentage error of reading from the meter front control panel. The system can record the amount of power to bring information to plan the expansion of the distribution system in the future. However some power station equipments to be installed such as unlocked - chopping blade switches whose functions cannot be controlled.
