A body of knowledge transfer classroom action research on academic work development for teachers in surin province
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.
Effects of ginger extract in the treatment of diabetic rats
The aims of this study were to investigate the effects of ginger (Zingiber officinale Roscoe.) extract on chemical compositions blood glucose levels body weight blood serum insulin levels and lipid profiles in diabetic rats. The experiments were designed to feed orally of ginger extract at a dose 250 mg/kg body weight in streptozotocin-induced diabetic rats for five weeks. The results revealed that the ginger extract significantly reduced blood glucose level lowered serum total cholesterol LDL and raised HDL blood serum insulin in diabetic rats or diabetic rat fed cheese closed to the normal controls and glibenclamide treated rats. These finding indicated that the ginger extract could be remedy as anti-diabetic agent and ginger health care. Because both normal rats diabetic rats and diabetic fed cheese rats receiving ginger extract weight higher than the control rats was statistically significant (p<0.05).
The application of multi-path adaptive TABU search algorithm in fuzzy logic controller design applied for four-leg active power filter
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
Using multimedia computers to promote the study on educational quality assurance
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.
Influence of the mordant on dyeing properties of cotton yarn with natural dye extracted from teak leaves
The objective of this research was to study influence of five different kinds of the mordant copper sulfate (CuSO4) ferrous sulphate (FeSO4) alum and chitosan on dyeing properties of cotton yarn with natural dye extracted from teak leaves. Cotton yarn dyeing with the extracted dye from teak leaves was carried out at 60?C for 30 minutes with a material to liquor ratio of 1:5. Three mordanting methods such as pre mordanting simultaneous mordanting and post mordanting were used. After that dyed clothes were subjected to measurement using CIELAB system and fastness tests. The effect of kinds of mordents on the hue of dyeing of cotton yarn shown that CuSO4 FeSO4 gave greenish yellow and yellowish brown respectively. While as alum and chitosan gave violet red. Moreover using CuSO4 (pre mordanting or simultaneous mordanting) and FeSO4 (simultaneous mordanting) improved fastness properties to light better than without a mordant.
