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 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.

This research aimed to compare the techniques and method used to solve non-linear equations with SEM. By Partial Least Squares (PLS) technique and Product Indicator Approaches (PIA) technique. Were tested by the two methods of case studies is motive in the decision to study at Bachelor degree in Rajamangala University of Technology Suvarnabhumi Suphanburi campus Information Technology field. For sampling 221 found Partial Least Squares (PLS) technique to solve the problem of non-linear equation. However the same study Product Indicator Approaches (PIA) technique do not use this method as error indicators for the model with a negative value wrong predictions by SEM. Can not be predicted by the model to them.

This research aims to study the application of kaolin with coconut fiber corncobs fiber and durian peel in concrete masonry unit wall for increasing effective heat protection and lightweight. The ratio of cement type 1: kaolin is equal to 1: 60 by weight. The kaolin is replaced by fiber include coconut fiber corncob fiber durian peel fiber with 1.67% 3.33% and 5% by weight of kaolin. The kaolin concrete block mixed with fiber sample size is formed to 6.9 x 39 x 19 centimeter with the hydraulic compactor. The samples tested in physical and mechanical properties follow the TIS 58-2533 standard. Resulting their fibers can reduce the density thermal conductivity and compressive strength and increase the changing length and water absorption of kaolin concrete blocks. The kaolin concrete block without fiber has highest compressive strength followed by the kaolin concrete block mixed with corn cob fiber the kaolin concrete block mixed with coconut meal fiber and the kaolin concrete block mixed with durian peel fiber has lowest compressive strength respectively. However their fibers have possibility to be composite materials to reduce weight of kaolin concrete blocks

This research aims to make a Bas-Relief book about Macreame tying for Career and Technology Level 2 for visual-impaired students of the Bangkok School for the Blind with standard efficiency of 80/80 and to study users’ satisfaction of the book. This sample in this study consisted of 10 blind students from the Bangkok School for the Blind who were purposively selected from level 2 (P.2 - P.6) in academic year 2555. This experimental research used a One - Short Case Study design. Instruments used in this research included Bas-Relief book observation and assessment skills to perform a visual relief and satisfaction survey. Statistics used for data analysis were Average ( ) Standard Deviation (S.D.) Percentage and Dependent t-test. It was found from the research that efficiency of Bas-Relief book was 87.93/95.76. Satisfaction with Bas-Relief book was high in every aspect ranking from the highest to the lowest as: content ( = 4.80 S.D. = .422) Braille character ( = 4.80 S.D. = .334) and material’s surface ( = 4.74 S.D. = .508).
