Normally bast fibres were removed from pineapple web by wrapping the boiled pineapple leaf with nylon web and stamp on it. If using this method it will take 24 hours to stamp on 40 kilograms of boiled leaf in order to obtain clean pineapple web that is suitable for producing paper. Apart from that when pressing the fiber we need to get rid of the water as much as we can because the fiber will be weight before using to produce paper. If the water pressed out each time is not equal there may be an error about paper thickness. Moreover stamping on boiled leaf may be dangerous because the chemical substance used when boiling the leaf may burn the feet and cause wound. Currently there is a Pressing machine to separate water from pineapple fiber Rachadasak Supengcum 2010 to fix the problems mentioned above. However there is a weak point because the pressing tube is small so it can press only 1 kilogram of leaf per one time. Therefore the new machine is designed to have a pressing tube sized 30 centimeters wide and 30 centimeters long. The pressing period is 30 centimeters and the pressure for pressing is 70 bars. It takes 1 minute 15 second for one squeeze which contains 6 kilograms of pineapple leaf. It can decrease the time for pressing from the old machine by 6 times. In addition the machine is designed to have the open-close channel to bring the pressed fiber out from the machine more easily. According to the experiment to remove the bast fibres from pineapple web the most appropriate amount for each pressing is 6 kilograms. The pressing process takes 1 minute 15 second. The remaining pineapple web after the pressing is 3 kilograms

The objectives of this study are to develop a management system for examination bank and an online examination. Working procedures were performed by analysis a traditional working system and problems study of user requirements design of a new working system and a development of the new system. PHP and JAVA programming language operating with MySQL for developments and a database management were used. The new system consists of 6 systems by operating as web application. Users are 3 groups that are teachers students and administrator. In the items analysis stem a reliability value was calculated using KR-20 and KR-21 of Kuder-Richardson. The level of difficulty and discriminating power were identified using choice analysis with 27 percentages of upper and lower technique. The new system was tested with 3 groups of teachers students and administrator. The evaluation was performed using questionnaires. The results of the evaluation shown the contentment is in good level. Accuracy of the system was measured by comparison between a traditional item analysis and the new system. The comparison results were not different. However the accuracy of item analysis results depends on knowledge of the students who are in testing.

The Purpose of this research is to design and to create the Font of Rajamangala University of Technology Phra Nakhon. The samples of this research are the internal personnel or internal staffs by using Cluster sampling (N1=50) and the external personnel or stakeholders by using Accidental sampling (N2=50) included 100 samples. The research tools are exploratory questionnaire satisfaction questionnaire and efficiency performance evaluation. Data analysis is done by using frequency percentage and standard deviation. Process of research methodology consists of (1) Primary survey about identity attitude (2) conclude and Analysis (3) Design and develop and create font (4) Satisfactory test (5) Efficiency performance of font

The objective of this research is to select a proper cumulative function for trend in an analysis of simultaneous multiple time series data with autocorrelation trend and outliers using a Bayesian method. The proposed model is applied to fluctuate stock price data in the stock exchange of Thailand. The data consist of the closing prices of 5 stocks. The algorithms are written in OpenBUGS and the performance of the model is evaluated via a simulation study in R. The cumulative distribution functions considered here are a Weibull cumulative distribution function and an exponential cumulative distribution. They are compared using RMSE MAPE and MAE as criteria. The research found that an exponential cumulative function for trends gives smaller values of the three criteria in both model fitting and model validation for the4 stocks EA NWR and KTB. However a Weibull cumulative distribution function gives smaller values of three criteria for the PTT in both model fitting and model validation.

The Applicability of the Royal Sufficiency Economy Principles to Community Enterprises Management in Surin. The objective was the possibility of applying the Royal Sufficiency Economy Principles. And compare investigate the possibility of applying the Royal Sufficiency Economy Principles. The sample is 316 firm from Community Enterprises in Surin is 1440 firm. The research found that Most of business was industry enterprise. Has capital an average of ฿146606 from private and relatives. The size of the enterprise community (NAV) of less than one million employs up to 10 people with qualifications below bachelor degree have annual sales of less than 2 million settlement enterprise in their local distributor. And supply of raw materials and equipment used in the production of their own local. The possibility of the application the Royal Sufficiency Economy Principles there is at a high level. And Compared to the possibility of applying found that communities that are difference characteristic there is a possibility of the application no difference on the 0.05 significance level.
