The objective of this research was to study the feasibility for producing the dry Dioscorea hispida powder as a thickener. The product was investigated in their properties the compatibility with dye and chemicals in print paste color appearance by indicated with color hue value the time durability storage the residual substance after washing treatment and the color fastness in washing and rubbing methods. The results shown the dry Dioscorea hispida powder was used as thickener that it was the good characteristic like the famous textile printing thickener as alginate. The dry Dioscorea hispida powder thickener was 10%w/w had the equivalent viscosity as 8%w/w alginate. It had 3 days stability storage and good compatibility for direct dye reactive dye acid dye and disperse dye print pastes. The color appearances were corresponding with owned hue in color index databases. The thickener was completely in washing process. And the washing and rubbing fastness were good to excellent.

This study evaluates the fatigue life of a closed-loop oscillating heat-pipe with check valves (CLOHP/CV). The method was predicting the fatigue life of the copper tube to apply for the CLOHP/CV. The fatigue test was carried out by using the specimens made of copper tube (C1220) at the temperature of 293 (room temperature) 473 and 573 K. The three types of hourglass shaped specimen included uniform type one-wave type and two-wave type specimens. It was found that the effect was a direct extension of material structures of specimen and hourglass shaped. It can be said that the number of cycles to failure (Nf) of the two-wave type specimen hourglass shaped specimen was rather sensitive to fatigue motion during testing and the temperature of 573 K has the greatest failure impact.

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.

The purposes of this research were to study and compare the company’s Opinion on the potentials of Co-operative Educational Programs of Rajamangala University of Technology Phra Nakhon (RMUTP). The samples of this research were the 253 companies’s staffs in Bangkok Metropolitan Region that looked after the students who were attended to the Co-operative Education project. The research tool was questionnaire and the data was analyzed by using frequency percentage mean standard deviation T-test Independent One-way ANOVA and analysis of the difference with the method of Sheffe by determining the level of significance statistic of 0.05. The results of the study showed that the company’s Opinion on the potentials of Co-operative Educational Programs of RMUTP was at the high level in every issue: their success in work knowledge responsibility and characteristic. The test’s results found that the differences corresponding with the hypothesis were the position of company’s staffs and the kind of businesses where the student worked. Conversely the gender of company’s staffs weren’t different and the experience of company’s staffs weren’t different which discord with the hypothesis. This result therefore Should be a guideline to improve and develop the Co-operative educational program of RMUTP in order to develop the student’s potentials corresponding with the company’s demand. It will make the employer more continuously accept the students to work for them.

The research aims to study the Conditions and Problems of Internal Educational Quality Assurance in Rajamangala University of Technology Phra Nakhon. The sample population included 320 staffts from RMUTP. The questionnaire was a research instrument. Analysis statistics was done by percentage arithmetic means standard deviation and frequency. The research results can be summarized as follows: 1. Overall Conditions and Problems of Internal Educational Quality Assurance in Rajamangala University of Technology Phra Nakhon was highly rated. 2. Problems and obstacles encountered in the implementation of quality assurance which are related to standards such as the quality of graduates standards of research productive standard of service standards Institute and Personnel Development. The problem in preservation of cultural standards standard curriculum and academic and standards of quality assurance is not found in the operation.
