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 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.

The objective of this study was: to experiment the activity using the (P) SPC2PAS model for Business Administration Undergraduates in Rajamangala university of Technology Phra Nakhon in (1) a comparison of achievement test of post-scores with pre-test scores of the first phase; (2) a comparison of post-test scores with pre-test scores of the second phase; (3) the result of the activity’s self-reflection of knowledge attitude and performance of learners; and (4) learners’ attitude towards an (P) SPC 2 PAS model. The research procedure was comprised of two phases. In Phase 1 there was the adjusted (P) SPC2PAS Model which was applied to use with Business Administration Undergraduates in Business Finance at Rajamangala University of Technology Phra Nakhon. In Phase 2 there was the experimentation of (P) SPC2PAS Model with Business Administration Undergraduates in Business Finance at Rajamangala University of Technology Phra Nakhon. The experimental group was the forty first-year financial undergraduates in the 2nd Semester of Academic Year 2010. The research instruments were: the business finance achievement test the self-reflective learning checklist and the attitude questionnaire analyzed by percentage mean standard deviation and the t-test. The result of the study showed that: (1) the mean scores of the sample group in the first phase of business finance comprehension’s post-test was significantly higher than of the pre-test at the statistical level of 0.05; (2) the mean scores of the sample group in the second phase of business finance comprehension’s post-test was significantly higher than of the pre-test at the statistical level of 0.05; (3) The learners’ spiral-learning development of the all activities’ self-reflection of knowledge attitude and performance of learners was 100 percentage; and (4) learners’ attitude towards using (P) SPC2PAS Model of Business Finance for Business Administration Undergraduates at Rajamangala University of Technology Phra Nakhon in the areas of the activity model teacher’s role instrument and learning evaluation was in mean scores at good to very good level-positive attitude.

The purposes of this research were to study and compare the factors related to the timely or late graduation of students at the Rajamungala University of Technology Phra Nakhon (RMUTP). The sample consist~d of 290 students of the Rajamungala University of Technology Phra Nakhon. The instruments used for collecting data were the 5 rating scales questionnaire. The reliability was 0.87. The data were analyzed by using SPSS for window. The statistics used were a -coefficients frequency percentage average mean t-test and Chi-square. The results were as follows: 1. Students background: The sampling group who timely graduated were mostly female studied in Faculty of Home Economics Technology and enrolled with high school certificate and got grade point average between 2.00-2.99. They were admitted through direct entrance examination. Their hometown was Bangkok and stayed with the parents who were together. The highest academic qualification ofthe parents was primary school. Most of the parents were venders. Their monthly income was over 15000 Baht. The parents were the financial supporters of the sampling group who mostly did not do part time jobs. Their grade point average was between 2.00-2.99. They went to the parents when they had problems. Students characteristic: The sampling group who timely graduated had learning problems about adjusting their learning style and not understanding the content taught. While the sampling group who untimely graduated had problems about health economics heedlessness from family members and learning problem on preparing special project and planning. Both groups had the same opinion toward teachers characteristic that the teachers paid a great attention on teaching. Most of the sampling group who timely. Graduated agreed that the teachers used easy to understand language. The sampling group who untimely graduated agreed that the teachers used the appropriate assessment method. For the opinion toward the learning environment most ofthesampling group who timely graduated agreed on the cleanliness of the registration process and the other group agreed on the sufficiency ofthe library to search for the information. 2. The factors related to the timely or late graduation of students show that sex faculty and grade point average (OPA) are correlated with both timely and late graduation (p< .01)

Study on the inhibition of germination and growth of weeds in rice fields. The extract from the leaves of Xy/ocorpus gongeticus Parkins and Porinori onomense Hance using fermentation Maceration and extraction techniques for Sequential Extraction with three types of solvent hexane ethyl acetate and methanol. The resuLts showed that Leaf extract of Xy/ocorpus gongeticus Parkins with ethylacetate at a concentration of 2000 -3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of Fl is the highest. Leaf extract of Porinori onomense Hance with hexane at a concentration of 2000 3000 ppm showed the highest inhibition of germination and growth of weeds. When the substance to be separated by chromatographic techniques showed that the extracts inhibited the germination and growth percentage of F4 is the highest. Which can be used for research and development of natural products from plants to control weeds in rice fields to develop further research to commercialization
