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.

Purposes of the research were to design and develop Computer Instruction Package on Principle of Object-Oriented Programming and to find out efficiencies effectiveness and leamers satisfaction towards the package. The research tools were: 1) The Computer Instruction Package on Principle of Object-Orientes programming 2) Achievement tests 3) Quality assessment and evaluation form for multimedia software and 4) questionnaire of leamers satisfaction. sampling groups composed of 30 Bachelor first year students from Faculty of Business Administration Program Computer Infomation-Business Computer Rajamangala University of Technology Phra Nakhon. Research results revealed that the efticiency of the Computer Instruction Package was at 81.08/81.05 corresponding with 80/80 criteria. Analysis of pre-test and post-test scores found that the effectiveness aftce the process (E) was at 81.08 it was higher than before the proecss (E) which was at 18.25. Therefore the Computer Instruction Package on Program Design and Development could increase the students learning effectiveness up to 62.83 corresponding with 60 criteria. Mean of satisfaction of the sampling groups was rathe at a high level (4.31). It could be concluded that the Computer Instruction Package on Principle of Object-Oriented Programming had the efficiency that could used for self study.

The purpose of this research is to study the evelopment of fair markets around the suburban area in Bangkok to study the existence of the markets fair and to compare the differences of the markets fair in each area. The researchs designed by using mix methods collecting data of both quantitative and qualitative. The areas of which have been studied cover the free markets at 1) Wat Don Kai Dee in Krathumban District Samutprakarn 2) Mahidol University Salaya District Nakorn Pathom and 3) Wat Thong Sa-Ard Bang Bua Thong Nonthaburi. The main target groups involve the sellers the customers and the owners. The concerned local administration group is a secondary target group. Data collection consists of e survey participating observation in-depth interview and questionnaires in supplementary of the interview. Qualitative data analysis was context analysis. Quantitative data analysis were the statistics of frequency percentage chi-squaret-test and one-way variance. The result of the study are as follows:1 All of the above-mentioned markets fair have been established in order to respond to the need of the community in each area at the same time around 1997. The peak time of Mahidol Market Fair is on Friday during 7.00 14.00. for Wat Thong Sa-Ard and Wat Don Kai Dee Markets the peak times are around 15.00 -19.00. 2.In term ofthe customer behaviour of the markets the costomers mostly came to the market every time when it is available. They occasionally buy the ready-cooked food. For Mahidol Market the customers will walk to the market and most of them are students and staffs of the University. For Wat Thong Sa-Ard and Wat Don Kai Dee Markets most of the customers will go to the markets by motorcycles. In term of time spent at the market the customers at Mahidol and Wat Thong Sa-Ard Markets spent more than an hour whereas those at Wat Don Kai Dee spent less than an hour in average. In term of the behaviour of the customers going to the market those at Mahidol Market came with their friends whereas those at Wat Thong Sa-Ard and Wat Don Kai Dee mostly came with their families. In term of the factors affecting the customers for the services the most important one is a variety of the products. The products that have been bought the most in all markets is the ready-cooked food. The reason for the customers to buy products at the fair market is the convenience in travelling. 3.The different characteristics of the three markets are the types of the products. As for Mahidol Marketit is the market for working people therefore the ready-made products such as cooked food and clothing are the most favourite and easily to be sold out. As for Wat Thong Sa-Ard and Wat Don Kai Dee Marketsthey are serviced for the community in the evening therefore the most favourite products are cooked food and fresh products for making food at home as well as the products that are used in daily life. For the price of the products Mahidol Market has higher price than the other two markets. It is because the types of products at Mahidol Market are the luxurious one and the location of the market which situated at the Faculty of Environment Department of the University whereas the markets at Wat Thong Sa-Ard and Wat Don Kai Dee are on the roadside. 4.The existence of the fair markets has based on these conditions 1) the characteristics of the owners 2) the compliance with rules and regulations 3) location which is convenient for customers 4) a variety of the products 5) the peak time 6) the needs of the customers and sellers 7) the power purchase of the customers.As for the expansion of markets it is found out that the markets has 1) the physical expanse and the increase of facilities and 2) has the increase of sellers and the adjustability of costomers behaviour as well as 3) the various types of the products.
