Thailand is on the way toward ASEAN Economic Community or AEC in the year 2015. The AEC aims to create one-solid base for production and distribution and concurrently seek mutual economical profits. A kind of business that may allow Thai entrepreneur to survive more easily in ASEAN is the selling and purchasing of goods and services via internet or ‘E-commerce’. The objective of this research is to study the factors that influence the development of E-commerce that will facilitate Thai entrepreneur when we enter AEC. The samples of our study are the group of E-commerce’s entrepreneurs who legitimately registered with Department of Business Development. Our research revealed that the major factors that influence the development of E-commerce is the knowledge in foreign language which is considered to be the source of major advantage for business with average at 3.9750. Follow by the opening of free trade area which will cause more obstacles in term of the increasing number of competitor with average at 3.8475. The lease is population’s preference that would directly affect business’s revenue with average at 3.7450.

The purposes of this study were to compare the progress in Thai enunciation skill of students at Rajamangala University of Technology Rattanakosin Wangklaikangwon Campus before and after using electronic medias and to find out freshmen’s attitude toward using electronic medias to develop Thai enunciation skill . The sample was 40 freshmen of Rajamangala University of Technology Rattanakosin and taking Thai for communication course in the first semester of the 2011 academic year. The study was carried out for 1 month by learning plan with the teacher before practicing unlimited time by themselves with the electronic medias 10 times with researcher consultation. The research instruments were 1) the electronic medias to develop Thai enunciation skill 2) the pre-test and post-test of reading 3) attitude questionnaire. The data were statistically analyzed using percentage by formula E1/ E2 and t-test The results of the study revealed that the Electronic Medias average percent effective E1/E2 is 80.15/88.90 after using E–learning the progress in Thai enunciation skill of the freshmen increased at the .05 level of significance and the freshmen’s attitude towards using electronic medias to develop Thai enunciation skill was very good.

The electronic science is complicated and highly abstract. The contents are abstracts and difficult to understand. This research was developed by computer assisted instruction lesson on electronic circuit multimedia using jigsaw puzzles. The objective was studied the achievement of circuit electronics and the satisfaction of students in grade 9. There were 132 students. The results from the pretest and posttest of computer assisted instruction lesson on electronic circuit multimedia. They have highly scores and satisfied.

This research studied behavior of price clustering in Electronic Trading Transaction and Block Trading Transaction in Thailand Futures Exchange market from SET50 Index Futures using daily closing price data of SET50 index Futures from April 28 2006 to June 302012 Descriptive statistics and quantitative analysis included Chi-square to test Uniform Distribution; Hirshmann Herfindal Index(HHI) to measure price density standardized Range and Excess Clustering to measure price clustering; and Multiple Regression to test behavior of price Clustering. Results showed that the behavior of price clustering in SET50 Index Futures was characterized in the same way. That is the most frequent last two digits were 00 (32.31%) and 50 (13.82%) while other last two digits had the frequency of not greater than 8%. There was more price clustering along with the trading volume. It also found that the opening price the bid-ask spread. And the volatility had positive impacts on price clustering while the closing price had negative impact. For the total retum no impact was found on price clustering at the signicant level of 0.05

The purpose of this research were to create and determine the efficiency of computer assisted instruction lesson on electronic circuit multimedia for secondary school students (grade 9) Triamudomsuksanomklaononthaburi school. The research sample consisted of 120 students of secondary school students (grade 9) during semester 2 in the academic year of 2012. The data were analyzed using mean standard deviation level of difficulty and discrimination power. The results found as follows : The efficiency of computer assisted instruction lesson electronic circuit multimedia for secondary school students (grade 9) is 80.15/83.35 and the students’ satisfaction with the computer assisted instruction lesson electronic circuit multimedia was at highest level ( = 4.60 S.D = 0.74)
