The purposes of this research were 1) to study the school academic administration of Rajamangala University of Technology Isan 2) to study the correlation between the administrative factors of school academic administration and the university academic administration of Rajamangala University of Technology Isan 3) to study Factors Effecting on the Administration of Academic Affairs of Rajamangala University of Technology Isan 4) to analyze the multiple regression of Factors Effecting on the Administration of Academic Affairs of Rajamangala University of Technology Isan. The sample groups were Teachers and Administrator in Rajamangala University of Technology Isan. The sample groups were 402 Teachers and Administrators selected through Simple Sampling. The research instrument was a 5 level-rating scales questionnaire with the reliabilities of part 2 and 3 were 0.89 and 0.91 respectively. The statistical Techniques employed in data analysis were percentage mean standard deviation Pearson Product Moment Correlation Coefficient and Enter and stepwise Multiple Regression Analysis by using the Computer program. The results were as follows 1. A whole and each part of the University academic administration of Rajamangala University of Technology Isan were high level. 2. The positive relationship of the administrative factors and the school academic administration of Rajamangala University of Technology Isan were high level and significantly at 0.05 3. A whole factors and each part of the academic administration of Rajamangala University of Technology Isan were high level. 4. For the forecast of best factor Enter and stepwise Multiple Regression Analysis it was found that the budget management(x5) characteristics of teachers(x2) University atmosphere(x6) the relationship between University and community (x3) Performance of administrator(x1) and the readiness of University of administration at 0.05 level significance (x4). If showed a stepwise Multiple Regression (R) of 0.80 finally the forecast for the University academic administration was at 64.40 percent. The forecast equations for the University academic administration were as follows: Equation of raw score: Y^ = 0.121+0.234(x5) +0.228(x2)0.113(x6) +0.134(x3) +0.136(x1) +0.112(x4) Equation of standard score: Z^ = 0.297(x5) +0.187(x2) +0.160(x6) +0.163(x3) +0.139(x1) +0.133(x4)

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.

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.

The reduction of calcium carbonate (CaCO3) particle was prepared by wet grinding method with 40% dispersion. The particle sizes of CaCO3 were studied with various time of wet grinding. It was found that the particle sizes of CaCO3 rapidly decreased in 3 day of grinding after that it was slightly reduce. Therefore the CaCO3 at various time of wet grinding were mixed with concentrate latex (60% dry rubber content DRC). The result showed that the wet grinding for 2 days provided the superior machanical properties. In addition the compound with epoxidized natural rubber (ENR) as a coupling agent was investigated. It was found that the 5 phr of 30% mole percent of ENR results in significantly improved mechanical properties of the rubber vulcanizates.

This experimental research had five objectives: 1) to develop Web-Based Instruction (WBI) on Computer Assisted Instruction Course Using Problem-Based Learning and Demonstration Technique; 2) to evaluate the efficiency of the developed WBI according to Meguigans’s standard; 3) to compare the students’ learning achievements by pre-test and post-test; 4) to evaluate the students’ practical work and 5) to measure the students’ satisfaction towards the WBI. The samples in this research selected by purposive sampling consisted of 24 under graduate students in Academic Year 2/2012 of Department of Computer Education Faculty of Technical Education King Mongkut’s University of Technology North Bangkok. The research tools consisted of six units of the WBI a student’s learning achievement test administered before and after learning with the WBI video demonstration and problem based questions. The statistic employed in this research were the Meguigans’s standard t-test mean and Standard Deviation. Research results showed that; 1) the efficiency of the developed WBI was 1.22 according to Meguigans’s standard; 2) the students effectiveness after using the WBI was significantly higher than before using it at .05; 3) the average score of the practical work was 88.68 higher than 80; 4) the students’ satisfactory was at a good level. In conclusion the developed WBI can be used for the target group properly.
