The objective of this research is to construct the appropriate forecasting model for the export quantity of concentrated latex by the three time series analysis methods which are Box-Jenkins method Winters’ multiplicative exponential smoothing method and combined forecasting method. Time series data from the website of Office of Agricultural Economics during January 1998 to February 2014 (194 values) are used and divided into two series. The first 182 values from January 1998 until February 2013 for the models prediction and the last 12 values from March 2013 until February 2014 for comparison the performance of forecasting models via the criterion of the lowest root mean squared error and the criterion of the highest correlation coefficient between existing values and forecasted values. Research findings indicated that for all forecasting methods that have been studied the most powerful method is the combined forecasting and the forecasting model is where and represent the single forecasts at time t from Box-Jenkins method and Winters’ multiplicative exponential smoothing method respectively.

The item bank framework on cloud computing is developed to present the concept progress of an information system which combines the features of the private cloud and the program development of software framework for the item bank service. The designs based on item bank frameworks of object oriented programming concept design. It leads to the new software that can be reused and has further development. The developed frameworks are divided into two parts: 1) the connection to the user interface which functions as the display and connection to the system and 2) the website service serves the exchange of data between distributed databases in servicer’s computers of the item bank service by the internet networking. The number of 15 samples in the research evaluation are the specialists in information technology and education. The statistics used in this research are the mean and standard deviation. The result revealed that the developed model is suitable at the highest level in all aspects except the service and implementation of the examination bank framework are in the high level.

The ultimate goals of Plant Genetic Conservation Project Under the Royal Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn are development of personnel and conservation and development of plant genetics resources for the advantages of Thai people. The objectives of this project are (1) to promote understanding and awareness of personnel and organization about the importance of plant genetic conservation; (2) to create links between various organizations including government agencies and private sections on virtue foundation; and (3) to build a plant genetics database system that is accessible around the country. The master plan has been distributed over a period of five years. The current operations are in the fifth year of the plan. The operation had three frameworks and eight supporting activities that focused on three resource bases: physical resources biological resources and cultural and wisdom resources. Rajamangala University of Technology Phra Nakhon (RMUTP) realizes the importance and the advantage of these resources. Thus RMUTP has followed the royal initiation with several activities that supported the royal initiative since 2005. These projects were conducted within the frame of the master plan with emphasis on utilization framework as well as establishment of good conscience.

The effect of chain extender on the improvement of molecular structure and rheological properties in shear and elongation of recycled poly (ethylene terephthalate) was studied. The results suggested that addition of chain extender increased the molecular weight and broader molecular weight distribution of recycled poly (ethylene terephthalate). A gel fraction of cross-linked material was formed and the amount of gel content was dependent on the amount of chain extender used. Moreover it was found that the addition of chain extender increased the shear and elongational viscosities of recycled poly(ethylene terephthalate). The increases of viscosities were explained that the extension of poly (ethylene terephthalate) chains caused a reduction in chain mobility. As for the tensile properties at the molten and solidified state it was seen that the increase of tensile properties resulting from chain extender rose up to 0.6 wt% before it reduced at the chain extender loading of 0.9 wt%.

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.
