This research was to determine the appropriated mixing ratio of bottom ash and admixture (dust rock and Portland cement type 1) for improving the compressive strength. Bottom ash was used instead of soil and the quantities of admixture were 0 2 4 6 8 and 10% by dry weight of bottom ash. The specimens were cured for 7 14 28 and 90 days. Results of compressive strength test show that the admixture of 8% was the best mixing ratio. The increasing primary strength is developed from hydration reaction and the increasing secondary strength at 90 days is developed from pozzolanic reaction. Moreover the compressive strength of this specimen is close to the compressive strength of laterite

The objectives of this survey research are to study perception participation and relationship of the factors influence the participation in food safety program. The population was health personnel with purposive sampling represented 30 samples. The tools were questionnaire and descriptive statistics included percentage and chi square test in which to analyze the relationship of the factors influence the participation. The result of this study revealed that the valid perception of the health personnel in 4 aspects of food safety program consisted of perception in danger of food contamination perception of food sanitation perception of best practices and utilities of food safety and perception of threads were generally in the moderate level. The samples participated in every steps of the food safety program which consisted of planning implementation and evaluation revealed that 35.67% of them had participated. The factors related the participation in food safety program had a statistic significance (p<0.05) included the status of consumer protection the information perception in consumer protection and frequency of implementation of the health personnel in consumer protection.

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

The aim of this research was to determine the effects of gender faculty and academic performance on the prevention of students to use to communicate on the Internet. Four hundred and thirty-three (male=225 and female=208) undergraduate students from 3 faculties including faculty of business administration and liberal arts science and agricultural technology and engineering in Rajamangala University of Technology Lanna Nan were used to fill in survey questionnaire. The results found that the gender had effected on the prevention oneself in the communication on the Internet. The male could prevent oneself more than female. In addition the student from engineering and science and agricultural technology could prevention oneself in the communication on the Internet more than faculty of business administration and liberal arts. However the academic performance had not affect on prevent oneself in the communication on the Internet. This study concluded that the prevention oneself in the communication on the Internet is affected by the gender and faculty but not the academic performance.

This research was to apply graphical method as the input data combined with using database for developing reinforced concrete slab analysis and design. Visual Basic language was used for creating the GUI (graphic user interface) and coding and database file was used for storing data. The position of beam column and slab can define by drawing on GUI and this program will automatic translate to be the distances for using as data in process of analysis and slab design. Results from analysis and design were compared with manual calculation that they are a litter bit error because of rounding error. Moreover they can be more economically and more conveniently than results from VisStructure 4
