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.

This paper presents a program developed for calculating magnetic field intensity of high voltage transmission line and high voltage distribution lines. This program was developed with Microsoft Visual Basic and Microsoft Access program was used to store the database of the peak ratings current height and space of transmission lines. The developed program was able to calculate magnetic field intensity of high voltage transmission line and high voltage distribution lines according to 2 standards of Provincial Electricity (PEA): “A 22 kV Single Conductor Circuit High Voltage Distribution System” and “115 kV Single Conductor Circuit High Voltage Transmission System”. The program was able to select structure of the electrical system to be calculated as well as types and specification of Transmission line from the stored database that corresponded with the structure. The calculated output waveforms were displayed on computer monitor. Results from the developed program enable more convenient and faster calculations of magnetic field intensity of high voltage transmission line and high voltage distribution lines and are useful for analysis of possible impacts on electric and electronic devices.

Nowadays one of major problems of SMEs is improperly planning the production to serve for the true demand of customers. Therefore this research was set the objective to apply forecasting techniques to predict the right demands and feed them together with other constraints as inputs for the LP model in production planning to get maximum profit and also conform to the restriction constraints such as production processes sales volume labor constraints inventory and investment requirements. As a result from this study the Decomposition Technique by Minitab program was the most accurate technique for sales forecasting of Quilt Products of Hmon-Oon Group. The sales forecasting information was then used as input to a mathematical model (LP) targeting maximized profit processing by Solver program in Microsoft Excel 2010. Eventually the business can gain more benefit by using this method from 358830 Baht in one quarter to 504425 Baht or 40.57% increase. Cost of inventory decreases from 17764 Baht to 16670 Baht or 6.16% decrease. Production labor hours in one quarter decreases from 2984.12 hours to 2378.77 hours or 20.29% decrease

The research aims to compare results of algorithm for solving allocation problem in multi-stage rice transportation between formulation of mathematical model with computation by Lingo V.11 and application of Differential Evolution (DE). The research was conducted in two stages: 1) comparing efficiency of the two employed applications in terms of economic and 2) comparing for minimum computation time. The proposed algorithm was tested with problems in six simulated case studies. Results show that in terms of economic DE did not generate better solutions than Lingo V.11 at an average of 0.525%. However it used faster response time at an average of 206 minutes when compared to Lingo V.11.

The objectives of this research were to study the effect of temperature on the roasted of paddy Sungyod Phatthalung rice with moisture content up to 12 percentage for popped rice production. Nutritional values including protein fat ash moisture content antioxidant activity and anthocyanin compound were studies. The temperatures used in roasting popped rice were three levels of 200 220 and 240 degrees Celsius. The result showed that all three temperature levels does not different effected to amount of protein fat ash and moisture content in popped rice. It was not statistically significant difference (p<0.05. Whereas the amount of anthocyanin compound and antioxidant activity decreased as the temperature increased. Temperature of 200 degree Celsius had the highest of anthocyanin and antioxidant activity showed 2.73 and 76.95 percentage respectively. It was statistically significant difference (p>0.05). The nutritional values in popped rice were lower than start paddy rice. The experiment showed that temperature was effected to reduced of nutritional values. Temperature range of studied indicated minimum decrease nutrition values of anthocyanin and antioxidant activity for the roasted popped rice was 200 degree Celsius.
