The aims of this study were developed geopolymer matrix for controlled release amoxicillin antibiotic drug in the in vitro gastric and intestines (pH 1 and pH 6.8 temperature 37 ºC conditions). Three formulations of geopolymer tablets (GeAmSF5 GeAmSF7.5 and GeAmSF10) which different silica fume content were used in this study. Geopolymer tablets were measured compressive strength and characterized by using 3D laser microscope Scanning electron microscope (SEM) X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The amoxicillin release was analyzed by UV-VIS spectrophotometer. It was found that amoxicillin in geopolymer tablet was more resistance with various extraction solvents (ethanol water 50 oC pH 1 and 12 solutions) than amoxicillin commercial tablet in 2 hours. Moreover the amoxicillin constantly release from geopolymer matrix after 3 hours in both in vitro gastric and intestines. However amoxicillin was more release in gastric than intestines condition due to the strong acid leached aluminum ion causing damages geopolymer structure. Mathematical modeling of amoxicillin release from geopolymer matrix was fitted best with Higuchi model indicating diffusion of the drug out of matrix.

The purpose of this research was to study the satisfactions of the trainees towards the services of Good Government official course of Ministry of Natural Resources and Environment. The research aims to 1) study the satisfaction of trainees for service of fiscal year 2015 2) compare to the basic factors of trainees for service. The 350 questionnaires were distributed to the trainees. It found that 346 questionnaires (98.85%) were returned. To analyze the data mean standard deviation t-test and one-way ANOVA were employed. The results of the study showed that satisfaction of trainees in training service in 5 aspects at the high level. In term of genders and sectors found that are male and female had different satisfaction in the confidence level of 0.05 But in term of lecturer and teaching technique there are no satisfactions satisfaction difference between male and female. And there are no difference in each sector at the 0.05 level but the training and the lecturer and teaching had different satisfaction.

This research was aimed to study personal factors related to work performance and internal environment which affected the ability of using information technology of Huachiew Hospital personnel as well as to investigate the relationship between organizational environment and the ability of using information technology of Huachiew Hospital personnel. 170 samples were used. In the collection is a questionnaire. Statistics used in data analysis were percentage mean standard deviation t-test F-test one-way ANOVA. And Pearson Product Moment Correlation. The statistical significance was calculated at the 0.05 level. The results of this study showed that Huachiew Hospital staff Factors affecting the ability of using information technology were at the medium level. In addition the level of ability to use information technology of Huachiew Hospital personnel at the educational level was at a medium level. Experience Different departments There was a statistically significant difference at .05 and the correlation between the environmental factors within the organization and the ability to use the information technology of personnel. Huachiew Hospital has a low level of relationship. Statistically significant at the 0.01 level

The Purposes of this research were to 1) study the impact on the motivation of the personnel. 2) To study the satisfaction that affect the motivation of the personnel. 3) Study on ways to enhance motivation in the operation of personnel. The survey sample size was 285 persons. Sampling Data were collected by questionnaire data and analyzed with Average Standard Deviation Interpretation of descriptive analysis. All of three topics the results showed in a moderate level. Suggestion about motivation of employees. First the board of directors should have obligingness with employees. Second also boost workers morale equally. Last the incentive approach is very satisfying with the universitys policy to encourage all personnel to make concrete progress in the profession.

The purpose of this research was to study 1) Rajamangala University of Technology Phra Nakhon personnel’s opinions towards organizational change from a public to national university and 2) to analytically compare the personnel’s opinions towards the change of organization from a public university to national university. The factors were classified into types of personnel gender age educational level work tenure salary and work department. The instrument used to collect data was a questionnaire; the data collected were then analyzed through frequency percentage mean standard deviation t-test f-test and One-Way ANOVA. Schaeffer Method was applied in case the significant difference was found at 0.05. The results of this research revealed that Rajamangala University of Technology Phra Nakhon personnel’s opinions towards the change of organization from a public university to the national university in terms of the structure technology organizational culture and as a person in the overall was at a high level. It was also found that the personnel of Rajamangala University of Technology Phra Nakhon with different educational levels demonstrated different opinions towards the change of organization from a public university to national university. Also Rajamangala University of Technology Phra Nakhon personnel from different faculties of affiliations were dissimilar in opinions towards the change of organization from a public university to national university.
