This research studies the potential for using waste ash from industrial and agricultural by–products as a geopolymer material. This paper presents a study of the resistance to chloride penetration and resistance to sulfuric acid of geopolymer mortar containing ground rice husk ash (RA) and ground bagasse ash (BA). Geopolymer mortars with constant liquid to ash ratio and similar flow were used for the tests. Compressive strength porosity chloride penetration test Rapid migration test of chloride depth chloride ion diffusion coefficient immersion test of chloride depth and weight loss with impressed sulfuric acid were investigated. Test results show that the workable flow of geopolymer mortar was in the range of 110–115% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH. Extra water was used to improve the workabililty. In case of rice husk ash geopolymer mortar the geopolymer mortars with high strengths were obtained with concentration of NaOH of 15M with the sodium silicate to NaOH ratio by weight of 2.5. However the bagasee ash geopolymer mortars with high strengths were obtained with concentration of NaOH of 10M with the sodium silicate to NaOH ratio by weight of 2.5. The use of rice husk ash and bagasse ash produces geopolymer mixes with good strength and resistance to acid and chloride penetration. The resistance to acid and chloride penetration is higher with an increase in the sodium silicate to NaOH ratio by weight of 2.5.

The purposes of this research were to collect the data about Thai cuisine from four regions to design and implement database about Thai cuisine and transfer on internet and to tranfer the technological database about Thai cuisine from four regions. The research process involved studying data collecting the lists of regional Thai cuisine : the North Northeast Central and Southern collecting the information about food recipes materials and tools choosing the appropriate data taking pictures materials and tools designing and implementing web database creating computer system developing computer system installing computer software in order to input data testing the system and transferring web database on internet. The result was found that regional Thai cuisine web database was divided into 4 categories21 Kinds of cooking methods 293 data of food with recipes 108 data of food without recipes 138 items of materials and 39 items of tools for perparing and serving food. Interested persons could reach our information about Thai cuisine from four regions at http://www.thaicuisinenetwork.com

Tertiary education of Rajamangala Phranakon University of Technology focuses on capital-based professional scientific and technological quality. Industrial Education Faculty is aware of the learning process to achieve the transfer of learning in the teaching industry. Learners to awareness the value in learning to fully develop their own development and to adjust to the pace of social and economic changes. From this text said. Need to conduct research on “competency based teacher education Act the full year 1999 demand of labor market” to find the necessary information and basic competency of teachers as technicians and labor market needs of the Act. Education change. The research found that respondents are male and 31.20 per cent of respondents are female 68.80 percent were aged between 20 to 35 years accounted for 92.40 percent of respondents state a year students. 70.70 per cent secondary graduates. a teacher / teacher is found that 26.4 percent of the level of demand for targeted education most needs at most – in the most. 1. Competency in the professional industry. Gradate student position in B.Sc. in industrial management system in the state teacher / teacher relationships in the work of human industry. 2. Competency in teaching. Knowledgeable. In management learning. (Same comments) about the skills. Ability to analyze and design media. In psychology for teachers.

The purpose of this quasi-experimental research was to study the effect of an English camping program based on Cognitive Behavioral Theory on students self-efficacy in using the language for communication. The population of the study 118 first-year students of the faculty . of Liberal Arts Rajamangala University of Technology Phra Nakhon in the academic year 2009 were divided by using simple random sampling into 3 groups: experimental· group 1 whose members were assigned to participate in the English camping program based on Cognitive Behavioral Theory; experimental group 2 of which the members were given the infonnation on Cognitive Behavioral Theory and how to develop self-efficacy in using English for communication to read ; and the control group. The instruments used were a questionnaire a self-assessment questionnaire on self-efficacy developed by the researchers and Before & After reviews The statistics used were percentage and t-test. The results were as follows: 1. The level of self-efficacy in using English for communication after the groups participation in the English camping program based on Cognitive Behavioral Theory was significantly higher at the level of 0.05 which was not significantly different at the follow -up. 2. The self-efficacy level after participation in the English camping program was significantly higher at the level of 0.05 than that of the experimental group 2 after being assigned to read. 3. The level of self-efficacy after participation in the program was statistically higher than that of the control group at the level of 0.05. 4. The qualitative data collected from the group participating in the program indicated an improvement in the level of self-efficacy in using English for communication.
