To study the relationship between personal factors and healthy food consumption of Diploma students in Ubon Ratchathani Vocational College 5.To study the relationship between knowledge about healthy food and healthy food consumption of Diploma students in Ubon Ratchathani Vocational College amount 313 students.The instrument used in the research is the questionnaire. The statistics used for data analysis is frequency percentage and chi-square values and sampling by method of landscape The results revealed that. 1) Most of the students are female aged between 18-20 years they are studying in the first year Department of Business Administration. They live in a dormitory Ubon Ratchathani Province they get money from their parents 51-100 baht and the index is in the normal range. 2) Most students have knowledge about healthy food. The index is in good. 3) The objective of consuming healthy food is for health. The types of health food that are most commonly consumed are fruits and fruit products. Frequency of consuming healthy food 3-4 times per week. The average cost of consuming healthy food is 51-100 baht per time and receiving health food news from YouTube. Where to buy healthy food is the fresh market / night market. The most popular healthy food items are fruit salads and soy milk. 4) The relationship between personal factors and healthy food that gender is correlated with the frequency of consumption of healthy food. Field of study housing characteristics and money received from parents per day correlated with the cost of consuming healthy food on average per time and the statistical significance is at the level of .05 5)The relationship between knowledge of healthy food and healthy food consumption found that there is a relationship between the frequency of healthy food and the cost of healthy food consumption per time and the statistical significance is at the level of .05

The objectives of this research are to design the load cell tolerance testing machine and demonstrate the tolerance of load cell with a tolerance test that has a beam length of 90 cm. It can create the compressed force at the load cell more than 1 kN The experiment cam be divided into 2 stages; 1.) verification of load range and 2.) linearity test. Both stages are tested at a temperature at 25°C using 10 to 30 kg of mass in the lowest compressed force condition of 0.091 kN and the maximum compressed force condition of 1.12kN As a result the linearity performance of the tolerance of the load cell test kit between calculated force and displayed value force are different 0.354 percentage only while the standard deviation of displayed value force and voltage signal output are 0.0013 and 0.0022 respectively. It reveals that the experimental result is reliable because of less than 1. In addition the tolerance of the load cell tolerance testing machine is 0.00300 (0.3 percent) which was calculated from the comparison of the tolerance specification of two main equipment that specified by manufacturer.
