The objective of this research were to focus the antioxidant activity and separated the chemical compound of crude extract from Feronia limonia Swingle branch. After that the optimum antioxidant of crude extract was used to prepare the antioxidant lotion. The result showed that crude extract had total phenolic and total tannin contents 41.99 and 52.35 g/ml ; respectively and also had antioxidant activity (IC50) 12.55 ?g/ml Whereas BHT and BHA had IC50 8.96 and 9.61 ?g/ml. The separation of crude extract can be separated into four groups (F1 F2 F3 F4) and the results showed that F2 has the strongest activity against the others with IC50 = 9.53 ?g/ml. Then F2 was analyzed with GC-MS and found that the structure were Hexadecanoic acid Ethyl ester Trimethylsilyl ester and Dioctyl ester. The lotion was odorless white color with no phase separation with pH 8.0

The objectives of this research were to study the information seeking method and problems of students at Rajamangala University of Technology Srivijaya Trang Campus the Faculty of Science and Fisheries Technology. The population in the study included 185 fourth year students who conducted a term-paper. The questionnaires were used to collect data and Cronbach’s alpha was 0.83. The data were analyzed by descriptive statistics (frequency percentage and standard deviation). The results showed as follows. Students rated that the university library was the Institutional information resource at the highest level. They mainly used the electronic resources. Students preferred to used the information written in Thai most. The modernity of information was mostly between 1-5 years. Students normally searched for the information 3-5 times a week. There were 3 main problems in seeking information: language was their barriers information was not matched with their needs and information resources were insufficient.

Machine Physical Therapy Cervical Spondylossis to create a pull back and pull the neck up of Machine Physical Therapy Cervical Spondylossis. There are two parts for the conventional system: the neck and the back but the neck was individual used. Moreover the resolution was not convenient to set as desired and it was also very expensive. In addition it was difficult to service and maintain. To solve these problems: this study was to implement a microcontroller to control the computer function in command 0-30 minutes and 2 mode operations. It was continue pulled and un-continue pulled from 0-60 seconds. It was found that this study saved the cost of buying back and higher efficientcy. The evaluation results conducted show the satisfaction level of 4 which means ‘good’

The purposes of this research were 1) to construct and evaluate the efficiency of the Computer Assisted Instruction (CAI) on Nuclear Physics class to have 80:80 effectiveness standards. 2) to compare learning achievement between pre-test and post-test scores after using the CAI 3) to study student’s opinion about CAI. Samples were the second year of Science and Technology students of the Rajamangala University of Technology Thanyaburi in 2011 academic year selected by simple random sampling. The first test was done by one-to-one evaluation and the second one by a small group in order to revise the CAI before implementing within the subject. The efficiency of the CAI was evaluated by experts both in content and production technique of the courseware. The results of this research were shown : 1) the CAI on Nuclear Physics contained the effectiveness at 87.00:85.33 which was higher than the standard criterion set (80:80) 2) the comparison between pre-test and post-test was found that the post-test score of students who studies with CAI were significantly higher than the pre-test score at .05 level and 3) the mean score of the student’s opinion about CAI was 4.35 shown that most of them satisfied the CAI on Nuclear Physics at good level.

The purposes of the study were to study the need competency and to develop the competency in information and communications technologies of teachers. The samples were 363 teachers of Rajamangala University of Technology Isan and 70 trainees of experimental group. There were 4 stages of methodology: 1) Study the basic information in order to analyze the need 2) Study the competency of ICT to analyze 3 parts of competency which were knowledge skills and features needed 3) Development preparation and 4) Training course development. The Tools were the questionnaire the achievement assessments of pre and post trainings and the evaluation of the training. The results revealed as follows: The need in information and communication technologies of teachers in 9 aspects was at the high level. The teachers training achievement is significantly different at the level of 0.05. After training the achievement is higher than before regarding the training course expectation teachers are satisfied with this workshop training at the high level. For the suggestion it should be follow-up continuously after training.
