The purpose of this research is to study the Rajamangala University of Technology Phra Nakhon student activities information system usage and payoff if it meets the requirements of the university in order to keep track of the students extra curriculum activities and to study the user satisfaction usage and payoff of the system. 385 samples were systematically randomly selected among 10153 students studying in the undergraduate class year 1 to year 3 and the personnel working in all Faculties of the university at the 95% confidence level. The study found the following results: The majority of the respondents mainly were female 54.5 percent 96.4 percent were students studying in year 1 41.3 percent and from Business Administration Faculty 36.9 percent. Overall satisfaction toward the student activities information system was at a high level with an average of 3.66. Overall usage of the student activities information system was at a high level with an average of 3.74 and overall payoff of the student activities information system was at a high level with an average of 3.77. The hypothesis testing showed that different personal factors including gender occupation/status class and faculty did not varied the satisfaction toward the student activities information system statistically significant at the .05 level. Different personal factors including gender occupation/status class and faculty did not varied the usage of the student activities information system statistically significant at the .05 level. Different personal factors including gender occupation/status class and faculty did not varied the payoff of the student activities information system statistically significant at the .05 level. Satisfaction toward the student activities information system including system quality information quality and service quality is positively related to the usage of the student activities information system statistically significant at the .05 level and the student activities information system usage is positively related to the student activities information system payoff statistically significant at the .05 level.

The purposes of the study were to investigate the level of each aspect of information technology use on the internet; and to compare the level of the Internet use of personnel working at Royal Irrigation Department (Samsen branch). 364 persons were the sample selected by Yamane sample size determination. The questionnaire was administered with as the instrument for collecting data which were analyzed by the frequency distribution percentage distribution standard deviation t-test and One-Way ANOVA. The results revealed that investigate the level of information technology use on the internet of personnel working at Royal Irrigation Department (Samsen branch) was relatively high in terms of the educational use. As for the purposes of the use for communication use the use according to the workplace policy and the use for entertainment were average; however in terms of the commercial use the result was quite low. Moreover different genders and educational levels revealed similar internet information technology use; opposite from age personal factors which resulted in 0.05 statistical difference.

This research aims to 1) set up analysis procedures and define the Information. 2) to Apply DMAIC to the information. 3) to comprehend the number of information models. 4) to Study the acceptance of Information models. And 5) to analyze the acceptance of the Six Sigma Quality indicators . Sample group consisted of 116 people included high-ranking executives middle executives specialistsand operational executives. The simple random sampling from the population of 424 people. The tools used in this research comprise the information models content correctness assessment forms acceptance assessment forms the information models and indicators. The results have shown that 1) the process for analyzing and defining the information consists of four procedures 2) the Information models can be formed with the five steps of DMAIC 3) applying DMAIC has shown that 42 models 4) The number of the populations accepting the models is higher than that of those who do not accept them with statistical significance at .05 level. And 5) The number of the respondents accepting the indicators is higher than that of those who do not accept them with statistical significance at.05 level.

To manipulate students data which participate in activity projects of the university.

In conclusion the system accomplishes in good quality able to enhance management of student activity system effectively.

The research aims were 1) to develop and find out the efficiencies of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching to be efficient in accordance with defined 80/80 criteria 2) to compare the learning achievement before and after learning of students who studied with the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching and 3) to find out the students’ satisfaction towards the program. A purposive sampling technique was employed to obtain the subjects of this study who were 30 Engineering students of Electrical Engineering Department Faculty of Engineering Rajamanagala University of Technology Pranakhon. They were registered in the second semester of academic year 2013. For instruments were as follows: the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching the evaluation form of the multimedia computer instruction program the students’ achievement tests and the questionnaire of students’ satisfaction. After the experiment the scores obtained from the test were analyzed by using percentage mean standard deviation and t-test. The results of the study showed that the efficiency of the multimedia computer Instruction program on Information Services and Information Searching for Information Services and Information Searching was 81.22/83.55 which was higher than the specified criteria of 80/80. The scores of after learning with the multimedia computer Instruction program were significantly higher than the scores of before learning at .05 level. And the students revealed that they were highly satisfied with the program.
