All test statistics is statistically significant at 0.05 levels. The results can be summarized as follows: 1. General information of answerers discovered that most students are male = 56.7% studying in 4 - 5 years curriculum bachelor degree = 84.2% and most students are faculty of Business Administration = 38.4%. Staff using specific questionnaires discovered that most staffs are female = 51.9% and to be under faculty = 11.1%. All of answerers status are students = 93.1% and students under faculty of Business Administration = 36.5% 2. Basic knowledge of Activity Transcript are discovered that most students = 52.71% are correct. The topic that most students got correct answer is Item 2) “Number of activities and number of hours activities of students who are studying in 4 - 5 years curriculum bachelor degree must attend?” = 67.6%. Most of staffs = 64.08% are correct. The topic that most staffs got correct answer is Item 6) “What kind of sources that students can attend activities?” = 96.3%. All of answerers (students and staffs) = 53.48% are correct and the topic that most got correct answers is Item 6) “What kind of sources that students can attend activities?” = 69.3%. 3. Satisfaction of students towards Activity Transcript of RMUTP when considering side by side discovered high average is structure of Activity Transcript = 4.13 and moderation is benefit of Activity Transcript = 4.13 and low average is student activity information system of Activity Transcript = 4.03. Satisfaction of staffs towards Activity Transcript of RMUTP when considering side by side discovered high average is structure of Activity Transcript = 4.08 and moderation is benefit of Activity Transcript = 4.07 and low average is student activity information system of Activity Transcript = 3.96. Satisfaction of answerers (students and staffs) towards Activity Transcript of RMUTP when considering side by side discovered high average is structure of Activity Transcript = 4.13 and moderation is benefit of Activity Transcript = 4.12 and low average is student activity information system of Activity Transcript = 4.02. 4. Comparison of average scores for the satisfaction of using Activity Transcript of RMUTP students and staffs classified by sex curriculum faculties and status discovered that students with different sex and faculties were satisfied towards Activity Transcript of RMUTP is different. Students with different curriculum were satisfied toward Activity Transcript of RMUTP is not much different. Staffs are different sex were satisfy towards Activity Transcript of RMUTP is not much different. Staffs from different faculties were satisfied towards Activity Transcript of RMUTP is different. In addition students and staffs with different status were satisfied towards Activity Transcript of RMUTP is different. 5. Suggestion: students and staffs more than half were perception of using Activity Transcript and overview of satisfaction toward Activity Transcript is high level. However when considering side by side and suggestion discovered structure of Activity Transcript is also decrease number of activities and number of hours activities in each curriculum for suitable structure and not impact to education. In addition presently activities created by faculties and university is not much sufficient and varieties for students. Student activity information system should be more promoted and adequate equipment for record number of activities is required. Moreover Student activity information system should be more stable accurate and efficiency for Activity Transcript of RMUTP to continuously maintain development of better quality and effectiveness.

This research aims to study strategies required for developing educational game for preschool students and the development processes involved. The sampling groups used in this research included 3 content specialists whose responsibility is to verify the content of the games and 17 specialists on educational game. The sampling groups are selected particularly from the central region of Thailand. The research findings reveal the insights from the majority of specialists on development of educational games for preschool children as follow: games such as picture-matching domino object ordering object categorizing detail observing and number addition & subtraction games are popular for teaching. Moreover the principles for applying educational games with lessons should be incorporated in the development of game strategies. In addition the main objectives and the development process of games should focus primarily on their ability to draw attention from students as well as the fun of playing and allowing students to practice lessons and participate in class activities. The tools used for developing games are computers and devices created by teachers themselves. As for the future of educational game the trend is the more involvement of technology through the use of computer or mobile devices. Problems in game development include limited budget for purchasing hardware and devices. On top of that training on game development is much needed among teachers. The research results can be concluded with the following 5 strategies for preschool students: 1) enhance teachers’ knowledge and skills 2) study details of different kinds of games 3) develop games 4) determine time used for playing game 5) evaluate the process of game development in 4 areas including type of game devices used rules and playing instruction.

Presently the rail transit system plays a major role in the commercial world that they currently use diesel engine not only causing to a lot of fuel consumption but also generating numerously pollution. Therefore this project aims to study the break-even point of investment under comparison of brake specific fuel consumption and pollution of locomotive engines. By experimental works there are 3 types of locomotive engine: Pielstick M.T.U. and Caterpillar which are the difference of the combustion chamber and the fuel injection systems. The simulation load on the static tests (Dynamometer) was used following the regulation characteristic curve which is standard of State Railway of Thailand. As a result of testing the engine using common rail type of fuel injection system M.T.U. was the lowest brake specific fuel consumption at all of engine by the average of all engine speed 206 g/kW-h of brake specific fuel consumption. It is lower than Caterpillar (Semi common rail with direct injection) which is 314 g/kW-h equivalent 34.39 % while Pielstick engine a mechanism fuel injection system is 389 g/kW-h equivalent 47.04 % For pollution area there are Hydrocarbon (HC) Nitrogen Oxide (NOX) and black smut. The engine with direct injection system relieved the previous substance less than the pre-combustion engine. Moreover the compound of carbon monoxide (CO) was found that the pre-combustion engine (Pielstick) discharged carbon monoxide (CO) less than the direct injection engine (Caterpillar) whereas the common rail engine emancipated same substan cenear by with the pre-combustion engine (Pielstick). However the new technology of the engines is high maintenance costs. Therefore a number of applications have to be needed to make a quantitative value for the investment.

The objective of this research is to use a stochastic process for building a model using Bayesian parameter estimation. The model is applied to the of crash prices and future prices of rice in Thailand for 120 moths including monthly closing average price of white rice 5% non-glutinous paddy 15% and Hom Mali non-glutinous paddy 105. The data are time series data containing autocorrelation trend seasonality and outliers. The algorithms are turned into codes in OpenBugs and the performance of the model is evaluated using simulation in R. The model with a Weibull cumulative distribution function trend the model with an exponential cumulative distribution function trend and the exponential smoothing model are compared. The root mean squared error (RMSE) mean absolute percentage error (MAPE) and mean absolute error (MAE) are used as the criteria. The results show that the model with the model with an exponential cumulative distribution function trend gives smallest RMSE MAPE and MAE for the crash prices of non-glutinous paddy 15% and Hom Mali non-glutinous paddy 105 for both model fitting part and model validation part. The model with a Weibull cumulative distribution function trend gives the smallest RMSE MAPE and MAE for the closing average price of white rice 5% for both model fitting part and model validation part.
