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 purpose of this research was to study state and problems of teaching management in general education. The research samples were 54 instructors of general education program and 364 students enrolling in general education courses Rajamangala University of Technology Phra nakhon in the second semester of the academic year 2014. The research tools were questionnaire interview and focus group discussion. The data were analyzed by frequency percentage mean and standard deviation. The findings were as follows: 1. As for students’ opinions on the general education content the overall opinions are at the high level and due to each program of general education the students’ opinions towards the implementation of Thai language ( = 4.00) social science and humanity ( = 3.67) and physical education ( = 3.38) are at the highest level. The students’ opinions towards foreign language for basic principles of further education are at the highest level ( = 4.01). 2. As for students’ opinions on state of teaching management in general education the students’ opinions towards the development of general education instruction according to Thai qualification framework for higher education are at the high level and within each aspect the students’ opinions towards interpersonal skills and responsibility are at the highest level ( = 3.81) followed by moral and ethical behavior ( = 3.79) and knowledge ( = 3.72) while mathematical analysis skills communication skills and information technology application skills rated the lowest ( = 3.52). 3. As for students’ opinions on problems of teaching management in general education the students’ opinions towards problems of general education instruction according to Thai qualification framework for higher education are at the moderate level and within each aspect the students’ opinions towards mathematical analysis skills communication skills and information technology application skills rated the highest ( = 2.80) followed by moral and ethical behavior ( = 2.75) and knowledge ( = 2.63) while interpersonal skills and responsibility are at the lowest level ( = 2.54). 4. As for the comparison of the students’ opinions on state and problems of teaching management in general education according to Thai qualification framework for higher education it was found that every aspect was statistically significant at 0.00 level. 5. As for instructors’ opinions on state of teaching management in general education the instructors’ opinions towards the development of general education instruction according to Thai qualification framework for higher education are at the high level and within each aspect the instructors’ opinions towards interpersonal skills and responsibility are at the highest level ( = 3.59) followed by moral and ethical behavior ( = 3.52) and cognitive skills ( = 3.34) while mathematical analysis skills communication skills and information technology application skills rated the lowest ( = 3.18). 6. As for instructors’ opinions on problems of teaching management in general education the instructors’ opinions towards problems of general education instruction according to Thai qualification framework for higher education are at the moderate level and within each aspect the instructors’ opinions towards mathematical analysis skills communication skills and information technology application skills rated the highest ( = 3.10) followed by knowledge ( = 3.05) and cognitive skills ( = 3.02) while interpersonal skills and responsibility are at the lowest level ( = 2.78). 7. As for the comparison of the instructors’ opinions on state and problems of teaching management in general education according to Thai qualification framework for higher education it was found that moral and ethical behavior interpersonal skills and responsibility were statistically significant at 0.00 level.

Thesis is the development of radio-controlled lawn mower which can move and cut the grass in the desired environment and dangerous to human. The objective is to develop a radio-controlled lawn mower. The results showed that the rate of fuel consumption of controlled lawn mower in to cutting grass. The height of the grass at 6 8 and 10 cm. It has the average fuel consumption is 113 117 and 123 ml. The average time in the mowing is 6.6 8.01 and 9.69 minutes

This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4

The cobalt catalysts (cobalt content by weight: 7% 10% and 15%) and cobalt-nickel bimetallic catalysts (cobalt-nickel content by weight: 3.5%-3.5% 5%-5% and 7%-7%) were studied in dry reforming of methane for hydrogen and syngas production. All catalysts were synthesized by the wetness impregnation method. The dry reforming of methane was carried out at 700oC atmosphere pressure using a mixture; CH4 and CO2 in ratio 1:1. The result showed that the good activity and stability depend on metal content in catalysts and the combined 2 metals as bimetallic catalysts. The optimum amounts of catalysts are 10wt% Co for mono-metallic catalysts 75%CH4 and 75%CO2 conversion and 7wt% Ni-7wt% Co for bimetallic catalysts 87%CH4 and 89%CO2 conversion.
