The objective of this research is to study the readiness and procedure of the personnel in coping with the entering Asean community from example group of 126 people which classified by sex ages position educational degree field of work salary and working life. This study uses questionnaire as a tool in collecting data that could be categorized in three aspects knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of faculty of Engineering Rajamangala university of technology phra nakhon which 58.25% classified by the educational field and 31.75% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects it appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages position educational degree field of work salary and working life in their readiness in entering Asean Community.
Permanent-magnetic-field, bean sprout, neodymium welding process
The objective of this research is to investigate microstructure and mechanical properties of brass welded by diffusion welding process. The diffusion welding (DW) of brass welded over lap joints bonding parameters were pressure at temperature 500 650 and 800 0C contact pressure of 12 MPa and holding time for 60 minutes respectively. The microstructure mechanical properties and behaviour during bonding were investigated. The results show that in weld zone (Bond Line) diffusion of atom the brass significantly. The mechanical properties after diffusion welding process increased higher temperature
Design of the printed loop antenna for HF-RFID system
In this paper the printed loop antenna is proposed for high frequency radio frequency identification (HF-RFID) systems (13.56 MHz). The proposed antenna is designed on the printed circuit board (PCB). The antenna structure consists of printed semi-spiral loop with rectangular structure patch at the middle of loop. It can provide the magnetic field distribution to cover the operating area with various directions that can improve the communication performance between reader and various tag orientations. From the measured results the proposed antenna has more efficient than the printed spiral loop antenna
