This research focuses on development of Multimedia and Interactive System through Network for Learning of Opportunities School. This system used as a channel for students to learn outside the classroom and used as a teaching management tool for teacher. Tools for system development were program Microsoft Visual Studio. Database management system with MySQL. Write commands to work with PHP and Java scripts. For evaluating efficiency of the developed system this research used Sample group to answer questionnaires. The population of research is teachers and students of the Bankamwa school (Weboonratsamakee) in totals 97 people. The result of experiment shows that group is recognized the performance of system in the higher level and the system has efficiency of working.

The purposes of the research was to develop the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon including found out the quality by the experts and the system users’ satisfaction. The research tools were as follows: 1) the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon 2) quality evaluation form and 3) a questionnaire on users’ satisfaction. Tool for system development of this research were Microsoft FrontPage and Macromedia Flash Version 8.0. The research sampling group consisted of 30 the administers and staffs educational from assurance departments. The results of this research was found that the quality evaluated by experts in content towards the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was as a good level the average mean was as 4.15 and the standard deviation was as 0.63 in order words. The quality evaluated by experts in multimedia was 4.16 on the average or at a good level and the standard deviation was as 0.41 in order words. The users’ satisfaction on the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was 3.97 on the average or at a good level and the standard deviation was as 0.06. Therefore the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was able to be used properly.

This research was aimed to studying the effect of bagasse ash on the properties of footpaths concrete slabs. Using bagasse ash a waste from the manufacture of ethanol instead of the OPC type I 10 20 30 40 and 50 percent by weight. Test results revealed that the compressive strength of concrete bagasse ash mixtures was less than the plain OPC type I concrete And decreased by the content of the bagasse ash. The flexure strength of the footpaths concrete slabs was laid in the same direction. Comparison flexure strength of footpaths concrete slabs on the standard (TIS 378-2531) found that can used 40% replacement of bagasse ash replacing in cement. For the percentage of water absorption of footpaths concrete slabs in bagasse ash concrete mixtures were higher than the plain OPC type I concrete mixture and every mixture is not exceeding standard. It was also found that the replacing cement with bagasse ash content increased the cost of footpaths concrete slabs were lower down. When replacing cement with bagasse ash in 40% cheaper than the cost of plain cement were up to 31% and according to the standard

This paper presents a CMOS voltage reference design which is widely used in electronic circuits both analog and digital circuits. In the conventional a CMOS voltage reference circuit design composed of several MOS transistors and complicated circuits the output voltage cannot be adjusted to any levels. Therefore in this paper proposed the CMOS voltage reference circuit design technique based on a new current combination circuit which it was reduced number of MOS transistors and the proposed circuit is able to operate without complex startup circuit. The performance of the proposed circuit is confirmed through PSPICE simulation results the circuit can be operated with supply voltage varies from 2V to 4V the output voltage reference is about 231 2mV at wide temperature range of -80 to 120 it has very low temperature coefficient of about 37.65 ppm/ and a total power dissipation of 7.37 W

A case study of community’s Ban Mai Fad Tambon Maifad Sikoa district Trang province. A sample was selected from 1193 cases were included as a sample. The purposes of this study were: 1) the structure of the family how to choose a pair of family members relationships occupation of the person in the family education and ethics in the community 2) the effects of cultural change in the community after the founding of Rajamangala University of Technology Srivijaya Trang campus. Analysis to determine the percentage by using Microsoft excels. The results of the study were as follows: 1) Family structure 31.52 percent is single family and 31.52 percent is the extended family. 2) Families are encouraged to choose their own spouses to marry a stranger much more. 3) Family relationships of persons in interdependent and live together as a kinship. 4) Families to teach children to recognize the importance of education. 5) Encourage the child to learn at a higher level. Teach children not to drink alcohol smoke. Encouraged to practice religious activities and encourage participation with the public events. 6) Family changed from large to small and medium local languages in communication. 7) Community changed after the founding of University was as follows: Increasing income there are various types of business increase social change from a rural society to an urban society more problems of teenagers and environmental issues such as waste problems.
