The purposes of this research were as follows : 1) to construct and find an efficiency of classroom action research on academic work development for teachers in Surin province as the 80/80 standardized criterion efficiency 2)to find the effectiveness index of classroom action research on academic work development for teachers in surin province 3)to compare pre-test scores and post-test score all lessons 4)to study the satisfaction of teachers after they join the class 5)to find the retention of the teachers after join the class in two weeks. The sixty teachers were area or simple random sampling selected from teachers on surin province this research conducted duringthe first semester academic year 2011-2012. 1) An efficiency of classroom action research on academic work development for teachers is surin province was 82.19/81.92 which higher than the 80/80 standardized criterion efficiency.2) The effectiveness index of classroom action research on academic work development for teachers in surin province was 0.7145.3) The results of the comparisons of pre-test scores and post-test scores all lessons were significantly different at 0.05.4)The results of the satisfaction of teachers among a classroom action research on academic work development for teachers among a classroom action research on academic work development for teachers in surin province was found to be a high Level(x=4.27).5) The retention of the teachers after join the class in two week was no significantly different at 0.05.

This paper presents the application of MATS Algorithm that used to find optimum membership function shapes for a fuzzy logic controller and used to find optimum limit range of a compensate reference current amplitude. This amplitude used to create three-phase compensate reference current signals that compare with three-phase compensate real current signals at hysteresis band current controller (HBCC) to generate gate drive signals of a FL-APF. The FL-APF delivers reactive power to point of common coupling and reduce harmonics components of all supply currents. The MATS evolution mechanisms were found optimum membership functions for fuzzy logic controller. The simulation results after setting optimum parameters were found that the fuzzy logic controller control active power filter to compensate reactive power at the point of common coupling and limit source currents THD to 5% in range and complied with IEEE 519 standard

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.

Arachis glabata is new variety forage which tolerates drought and provide high protein.This kind of plant is suitable as dairy cow diet. The research was divided into 2 experiments Experiment 1 was conducted to study on nutritive value of Arachis glabata.The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three crops) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that three variety of Arachis glabata were 28.26-30.75 % of dry matter (P>0.05). In addition Arachis glabata Cv. Arbook was grater 19.78 % of protein than other group of Arachis glabata (P<0.01). Furthermore Arachis glabata Cv. Florigraze was grater 17.63 of hemicelluloses and 3830.00 kcal/kg of gross energy significant different among other group of Arachis glabata (P<0.05). Experiment 2 was conducted to study on ruminal degradability of Arachis glabata using In situ technique in dairy cattle. The experimental design was Randomized Completely Block Design (RCBD) experiment with three treatments. Each treatment consisted of three blocks (three ruminally fistulated dairy cattle) and followed different three variety of Arachis glabata as Cv. Florigraze Cv. Arbook and Cv. Ecotart. Results showed that Arachis glabata Cv. Florigraze and Arachis glabata Cv. Arbook was grater dry matter organic matter and protein degradability at 0-4 hour and 24-28 hour than Arachis glabata Cv Ecotart (P<0.05). In addition kinetic of degradation (a b c and p) of dry matter organic matter and protein were not significant different (P>0.05) among three variety of Arachis glabata.

The comparison of methodology from and -spectrometry methods has been made for freshwater sediment. The differences of precisions 18% and 15% were found for ? and -ray spectrometry respectively. Results from the analysis of certified reference materials (IAEA-326 327) showed good agreement with recommended values and data available in the literature. Thus an alternative methodology based on alpha/gamma activity ratio was developed and tested using different samples. The method is based on the determination of total -activity (46.53 keV peak associate with Pb-210) and the total -activity present in the aliquot. Differences between methods could be caused by different behaviors of Pb-210 and Po-210 (used for alpha measurement) in the freshwater sediment. In gamma spectrometry errors may arise when many gamma emitters are measured simultaneously and their activity peaks overlap. In alpha spectrometry chemical separation of Po-210 may result in analytical error due to incomplete sample dissolution. Pb-210 activities derived by alpha and gamma methods are shown to agree within counting error. The inherent compatibility of analytical results based on alpha or gamma techniques is established. Nevertheless the choice of an alternate method to determine the freshwater sediment criteria to time comfortable convenient and budget.
