The objectives of this research were to find the correlation between the milling degree and the milling quality of rice which was the basic data to investigate the milling degree equipment. Chainat 1 and KDML 105 rice varieties were milled at difference degree of milling (DOM) which calculated from bran removed. The study revealed that as the DOM increase the milled rice and head rice decreases. Therefore the whiteness transparency and milling degree of milled rice which was measured from Milling Meter also increased. When the DOM increased the whiteness transparency and milling degree also increased. The DOM had highly correlation not only to milled rice and bran but also to milling degree from Milling Meter at R2=0.99 and R2=0.97. So these correlations could be used to investigate the milling degree equipment.

The learning of Educational Quality Assurance topic has been important for students and educators. The nature of the topic has more complex contents of key performance index (KPI) and students are asked to learn by following the text books. Consequently the topic is not interested and the students and teachers lack of interaction during learning on the topic. Therefore this study developed the multimedia Educational Quality Assurance to provide a self-study and to enhance students’ understanding in this matter more. The sample group consisted of 60-third year undergraduate students on Technical Education learned Quality Assurance course. The results of this study shows that participating students have post-test score more than pre-test score significantly with the confidence level of 95% and have learning progression (normalized gain =0.62) implying that they could learn more with the developed multimedia. Moreover they get high satisfaction (4.52) with the developed multimedia.

The number of sample size was 364 households in the communities. The research data were collected by questionnaires and analyzed by using descriptive statistics (SPSS for Windows version 19 ).The results showed that total water quality including DO BOD TCB FCB and NH3-N in the summer was at the moderate level (WQI 58 - 68). The Li River utility was at the moderate level (Mean = 2.73 S.D. = 0.57). The relationship between the water quality and the river utility for agriculture had a statistically significant correlation at 0.05 (p –value 0.04).
