The objective of this study is to compare three forecasting methods on three agricultural products consisting of fresh whole chicken (include bone no entrails) red meat pork hip section and Jasmine rice. These methods are Simple Exponential Smoothing method Holt’s method and Winter’s method. Data are colleced for a period of 60 months from January 2007 to December 2011. The most suitable forecasting method are the one that shows no residual autocorrelation and gives the lowest MSE MAPE. The results show that Simple Exponential Smoothing method is the most suitable method on three agricultural products due to this method reveals no residual autocorrelation and displays the lowest MSE MAPE.

Study the chemical structure of the bioactive compound extracted from the leaves of the Ficus hispida Linn with extraction techniques Sequential Extraction using three organic solvents hexane ethyl acetate and methanol . Phytochemical examination testing antimicrobial activity of crude extracts and fraction of methanol extracts with the four species of microorganisms Vibrio cholerae Staphylococcus aureus ATCC 25923 Streptococcus mutans ATCC 27175 Vibrio paraheamolyticus and to determine the molecular structure of compounds. The results showed that 1. Crude methanol extract of the leaves of the Ficus hispida Linn show inhibitory microbial species more than crude extracts of hexane and ethyl acetate . 2. Testing antimicrobial activity of methanol extracts fraction was found to inhibit microbial highest F5 show. 3. The molecular structure of compounds crystals are colorless mp. 188-195 0C. Research should further study the molecular structure and biological activity of bioactive compounds in other areas including anti-cancer Antimalarial and antioxidant activity of different parts of the study. The roots leaf flower and fruit seeds to plant information for the selection and to further develop research in the next commercial.

The objective of this research was to survey research data of Rajamangala University of Technology Phra Nakho n that was 1) published 2) cited and 3) published with regard to the collaboration of its researchers with those of other universities in both national and international journals during the years 2008-2011. Such related data was collected from journals that appeared in 1) the database of Thailand Journal Citation Index Centre (TCI) 2) Web of Science database (WoS) and 3) RMUTP Research Journal. Analyses applied included social statistics particularly descriptive statistics which were frequency percentage and weighted score from six indicators. From the survey it was found that there were 559 lecturers and researchers in Rajamangala University of Technology Phra Nakhon. 67 out of 559 (12 per cent of the total) had research work published. The most important findings are as follows: 1. During four years (2008-2011) the university had 80 published research articles. 96.25 percent of the total were published nationally and 3.75 percent internationally. The total weight is 52.88 and the weighted score is 9.46. 2. There was only one article that was cited in a national journal in the year 2010 representing 1.25 percent of the total. The total weight is 1.00 and the weighted score is 0.18. 3. There were 18 articles or 22.50 percent of the total that were produced under the collaboration with researchers from other universities. The total weight is 23.00 and the weighted score is 4.11

The purposes of this research aimed to 1) develop the instructional packages namely Vector Quantities and 2) compare the achievement scores of the experimental group and the control group. The samples were 60 Computer Science students of Faculty of Science and Technology at Rajamangala University of Technology Phra Nakhon who took Principle of Physics course in semester 1 academic year 2013. They were purposely selected as an experimental group (30 students) and a control group (30 students). They were given two different treatments ; teaching with the instructional packages and the conventional teaching. The research instruments for the experimental group were the instructional packages comprised lesson plans instructional documents and instructional media whereas the control group was taught with only instructional documents. After of the experimental process both of them were given exercises and teacher’s feedback. Then they were tested to see their achievement. The test was 20 multiple choice items which had the degree of difficulty between 0.33-0.77 the degree of discrimination between 0.30-0.77 and the degree of reliability coefficient at 0.73. The analysis of data comprised 2 parts as follows: 1. The development of instructional packages was evaluated by using statistics One – Sample t -test on Vector quantities Demonstration and using statics in terms of mean on the lesson plans instructional documents and instructional media . 2. The achievement scores were evaluated by using t-test at the level of 0.5. The results of this research revealed that : 1. The quality of the instructional packages was excellent. 2. The achievement scores of the students who studied with the instructional packages were higher than those of the control group at the level of .05

The main problems of learning skills of a physics I for engineer’s course due to the lack of standard computer assisted instruction multimedia and its abstract nature therein were improved and repelled by using the invented teaching animation modules. Applying the established e-learning multimedia modules to the registered students from many faculties of the Rajamangala University of Technology Phra Nakorn via the learning management system it found that the improvement recipes have appropriate to increase both the learning skills and their highly attitude to this subject. The improved students by the invented media can effectively apply the contents to the higher levels study of concerning subjects.
