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.
The study of problems of epoxy adhesive on head gimbals assembly process
Head gimbals assembly (HGA) an important part in hard disk drive is made by assembling slider on suspension by using an epoxy adhesive. In production process there are three main problems originated from epoxy adhesive which are the instability of adhesive’s viscosity while it is in an operation air bubble in adhesive and low degree of curing which is not enough to adhere slider on suspension. The instability of adhesive’s viscosity was solved by preheating the adhesive at 60oC for two hours before use but it may be unsuitable because the viscosity increased due to curing reaction and adhesive’s properties are changed. Air bubble in the adhesive was removed by the supplier using a degassing method and vacuum centrifuge. Contamination from a surfactant for decationization on surface of suspension and a cleansing agent for cleaning slider before assembling HGA process they could act as inhibitors of curing reaction which is evidenced by the Differential Scanning Calorimetry (DSC) pr

The aim of this research is to study white and colour resist printing of dye extracted from dry nipa palm shell. The printing recipes and fixation condition were studied in this work. The result of white resist printing showed that 30 % owp of sodium carbonate (Na2CO3) was used to be a resisting agent. The steam fixation for 15 minutes was suitable to show a good white resist printing in whiteness and sharpness of printing pattern. The whiteness value was 35.05. The washing and rubbing fastness were good to very good and light fastness was fair. The tensile strengths of warp and weft directions were decreased to 10.29 % and 4.25 % respectively. The colour resist printing was using Curcuma longa Linn. powder as illuminant dye. The dye was miscible in 30 % owp of sodium carbonate. The colour resist printing results were corresponding as white resist printing results. The 15 minute of steam fixation showed a good colour resist printing. The Curcuma longa Linn dye could be fixed on silk fabric and showed a good colour strength and sharpness of pattern. The washing and rubbing fastness were good to very good. And light fastness was fair. The tensile strengths of warp and weft directions were decreased to 18.37 % and 4.18 % respectively.
The factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP
The objective of this research is to find out the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP by using questionnaire. The questionnaire is separated into 2 parts the first part is to find out the satisfaction level of each factor and the second part is to find out the effective level of each factor. After the researcher analyzed the data of tested questionnaire of 169 samples students by using Simple Sampling method from 294 students who study in the subjects which are fulfilled by using e-Learning the information were as follows: 1. The satisfaction level of factors is between normal And high the mean of satisfaction level of computer and internet infrastructure factor is normal ( x = 2.81) the mean of satisfaction level of supporting e-Learning system factor is normal ( x = 3.27) the mean of satisfaction level of the supporting personal factor is high ( x = 3.50) the mean of satisfaction level of e-Learning benefit is high ( x = 4.11). 2. The mean of effective level of computer and internet infrastructure factor is very high ( x =4.29) and the mean of effective level of supporting e-Learning system factor is normal ( x =2.98) In concluding to above information the computer and internet infrastructure factor is the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP.
