The objective of research is to study the problems knowledge attitude and practice The relationship of knowledge and attitudes and the relationship of the attitude and practice. The population is 117 staff of Faculty of Business Administration and Liberal Arts.117 The questionnaire is to used as an instrument. Data analysis included Frequency Percentage Mean Standard Deviation and Correlation Coefficient. It was found that the problems was at a high level the knowledge was at a medium level. Additionally they mostly had a positive attitude. Finally in practice it was averagely rated at a high level. The study showed the knowledge did not relate to the attitude and the attitude related to the practice of the quality assurance system as well. The correlation coefficient was .095 and .480 respectively and were significant at the .01 level.

The objective of this research was to study and evaluate of the efficiency of moisture separation from hydraulic oil. This method was conducted by mixing pure water and oil in an oil tank which was classified into 4 cases: 250 ppm. 500 ppm. 750 ppm. and 1000 ppm. The results showed that when the maximum quantity of water was 1000 ppm. the 710 ppm. of moisture could be separated from hydraulic oil. The highest temperature at 70ฐC was utilized when that water was 750 ppm. The maximum efficiency was 80% when the quantity of water was 500 ppm.

Hydraulic machines were used in both medium and large scale From industries studying problems of hydraulic systems around 70-80 percentage of the machine expiration was due to the deterioration of hydraulic oil from contamination so the best way to maintain the hydraulic machine was to take care of hydraulic oil to have the purity level and other properties suitable for the components in those machines. This article described the duty of hydraulic oil types of contamination sources of contamination the standard for measuring the purity level of oil equipments used to measure and analyze the contamination in hydraulic oil recommended purity levels the effects from the contamination in hydraulic oil to machine and methods to protect and to eliminate the contamination in hydraulic oil. All of these were useful as the guidelines to maintain the hydraulic machines to work in high efficiency and more long life time.

The purposes of this research were 1) to find the effectiveness of multimedia for learning on Basic carving in the lesson on Ready-to-eat fruit Home Economics 2) to find the Rater Agreement Index (RAI) towards the Basic carving work of students studying with multimedia on Basic carving in the lesson on Ready to eat fruit Home Economics. 3) to study the students satisfaction towards multimedia on Basic carving in the lesson on Ready-to-eat fruit Home Economics. The research is experimental research. The sample consisted of 19 students who studying in Mathayomsuksa 3 of Nong Ya Sai Wittaya School Suphan Buri Province by using cluster random sampling method. The tools used in the research were multimedia media quality assessment form performance assessment form and satisfaction assessment form. The statistics used in the data analysis were the Content and Objective Conformity Index (IOC) the Rater Agreement Index (RAI) percentage mean and standard deviation. The results showed that 1) multimedia efficiency on Basic carving in the lesson on Ready-to-eat Fruit Home Economics are equal to 80.00/84.21. 2) Assessing the consistency of the assessors score the overall Rater Agreement Index (RAI) was 0.89. 3) Student satisfaction with multimedia on Basic Sculpting in the lesson on Ready-to-eat Fruit Home Economics. Overall the students satisfaction was at the highest level (X= 4.77)
