The experimental models of electric fields were set up by using 4 forms of electric poles a point - point point - rod parallel rod and coaxial ring. The equipotential lines and electric line of force were drawn by using Microsoft Office Visio Program 2007. The drawing of equipotential lines and electric field had shown the direction of electric field moving from the positive electrode toward the negative electrode and perpendicular to the equipotential line. The point - point poles in 10 cm. distance have constant and the highest electric fields which is 28.64 V/m. The electric fields of point - rod parallel rod and coaxial ring are 60.51 V/m 45.81 V/m and 181.98 V/m respectively.

The goal of this study is to study the cost of safety system in building construction by studying multipurpose building with durable goods project. The cost of safety system in building construction is divided into two categories are the safety measure cost and the safety program cost in construction. From the study it is found out that the value of safety measure cost is approximately 1.85 % of a project cost and the value of safety program cost is approximately 0.98 % of a project cost. To sum up the cost of safety system in building construction is approximately 2.83 % of a project cost .Moreover the study found out that the safety measure cost is higher than the safety program cost about 1.88 as much. From the data of this study it can be used as the guideline in estimating the cost of safety system in building construction for the future project.

The study of ethical behaviors through students perception in the field of business administration in Rajamangala Institute of Technology Bangkok Commercial Campus was a study to find seven ethical behaviors of the students those were : honesty discipline generosity responsibility hard-working self-reliance and gratitude. The purpose of this research was to study seven aspects of ethical behaviors through students perception and compare the ethical behaviors between sex and learning achievement. The sample of this study selected by using simple random sampling technique from students in six majors of business administration field of study. In each major -Accounting Marketing Infonnation System Management Business English and Finance -50 students was selected as sample of the study totally 300 students. A questionnaire was used in collecting data. The findings were as follow : It was found that the ethical behaviors through the students perception was totally in high level. As for each aspect it was in high level 5 ones -gratitude honesty self-reliance discipline and responsibility respectively. For the medium level there were two aspects: hard-working and enerosity. The comparison of ethical behaviors through students perception by sex found that ethical behaviors of male students were totally in the medium level and female students were in high level. When considering in each aspect ofboth sexes the highest means was in gratitude honesty was lower. The total of comparison was found statistically significant difference at the 0.5 level. It was also found that there were four differences in statistical significance at the 0.5 level -honesty discipline responsibility and self-reliance. The comparison of ethical behaviors through students perception by learning achievement found that totally ethical behaviors of students with low achievement (lower than 2.00) were in the medium level. Students with medium achievement (2.00 -2.99) and those with high achievement (3.00 -4.00) were in high level. When considering each aspect of students with low medium and high achievement the highest means was in gratitude and followed by honesty except students with low learning achievement the lower level was discipline. The result of totally comparison was different at the 0.5 statistical significance level. There were two different aspects with statistical significance at the 0.5 level in the aspect of honesty and self-reliance.

The purpose ofthis research was to create and find out the efficiency ofthe Computer Assisted Instruction (CAl) on the topic TIG Welding Process to the standard 90/90. And the learning achievement was analyzed after using this CAl The subjects used in this research were the second -year engineering students Industrial Technology Department the Faculty of Engineering at Rajamangala University of Technology Phra Nakhon who enrolled in this subject. The experiment started at the students did the pre test on the topic TIG Welding Process before they studied this lesson. Then they studied this lessonbyusingCALAfterthattheydidthepost -testonthistopicagain.Theresult ofbothtests was calculated to find out the efficiency of the CAl and analyzed the students learning achievement. The finding revealed that the efficiency ofthe CAl was efficient reached to the standard 90/90. In addition the students learning achievement was increased at significant level of 0.05 after using the CAl.
