Non-destructive test with Acoustic Emission technique was used for monitoring of the corrosion in the above ground oil storage tank. In the analytical characteristics of acoustic emission wave however Acoustic Emission test has to be prior used for the location detection of corrosion especially indication of the severity of corrosion. In this research the relationship between the corrosion rate and the sound wave energy was studied. The corrosion and damage detected on the surface of the aboveground storage tank was determined by the Acoustic Emission Test. Nine pieces of low carbon steel grade SS400 was soaked in sodium chloride solution in simulated tanks at concentrations of 1.5 3.5 and 5.5 wt%. Next the corrosion activity was checked by performing with the Acoustic Emission Testing for 1 hour and thus calculating the corrosion rate of the test specimens. From the experiment it was found that the rate of corrosion affects the Acoustic Emission Energy. The corrosion rate was increased with the concentrations of the solution increasing from the corrosion process. The corrosion rate was also increased with the sound wave power increases. Therefore in order to achieve the corrosion rate and the position of the defects on the inner surface of the tank non-destructive testing with acoustic emission technique can be factually chosen for this specific application.

The purposes of this research were 1) to study the individual factors of Vocational Certificate students in Kanchanaburi Vocational College 2) to study of the breakfast meal knowledge of the students 3) to study their category of breakfast consumption 4) to study the relationship between the students’ individual factors and category breakfast consumption and 5) to study the relationship between the breakfast knowledge and breakfast consumption of the students. The target group was 285 Vocational Certificate students. The employed research instrument was a questionnaire. The statistical methods used in analyzing the data were frequency percentage mean standard deviation and chi-square. Stratified random sampling was used in this research. The results show the following: 1) regarding the individual factors of the students the main target group is female students aged 16 years in Vocational Certificate Year 1 who study in the Business Computer department; the parents of the main target group are employees; the students receive 50-100 baht per day from their parents; and their Body Mass Index is normal; 2) the students’ knowledge of breakfast consumption was at a very high level; 3) the reasons for their choice of breakfast are convenience and quickness; they prefer one-dish meals; the cost ranges from 31 to 40 baht; meals with little taste were consumed; the place of purchasing is the college canteen; positive influences were the cleanliness of sellers freshness of food and use of ceramic plates; 4) the individual factors had a strong correlation with category breakfast consumption with a significance at the 0.05 level; and 5) the students’ knowledge about breakfast category correlated with their consumption in relation to daily consumption the consumption of blade loin food with crispy mixed or vegetable in a main dish consumption of fast food meal for breakfast drinking a substitute for the meal and consuming snacks for breakfast with significance at the 0.5 level.

The aim of this paper is to study 1) personal factors 2) food consumption style and 3 ) correlation between personal factors and food consumption style of students at Rajamangala University of Technology Phra Nakhon. This experiment was constructed with 3 8 5 participants who are undergraduate students at Rajamangala University of Technology Phra Nakhon using questionnaires. The participants were stratified random sampling. The result was analyzed using statistics in frequency percentage and chi-square value. The result demonstrated that 1) the major personal factors were 20 year old female sophomore and studied business management. The daily income was less than 2 0 0 baht per day. 2 ) according to the study of food consumption style of students at Rajamangala University of Technology Phra Nakhon it revealed that the main reason to choose lunch was an inexpensive price. Most of participants preferred one dish meals such as stir-fried basil soup fried pork and noodles. On the other hand they chose sausage for fast food and papaya salad for snack. Most of the participants prefered drinking water. The average price was about 51-100 baht each meal. The participants often had lunch at a cafeteria or restaurant in the university. Moreover friends got involved in making decisions regarding meal choices. The main ingredients in the chosen foods were meat and products from meat. 3 ) the correlation between personal factors and food consumption style of students at Rajamangala University of Technology Phra Nakhon proved that the level of education related to frequent chosen lunch menus. The faculty also involved in frequent chosen lunch menus the cost and the location. The daily income correlated to frequent chosen lunch menus and the cost of meal which was statistically significant (P-Value?0.05)

Watching movies in cinema is a popular channel for moviegoers for a long time. In addition to the cinema there are also online movie channels giving viewers more choices. Therefore cinema operators should continue to develop business to meet moviegoers needs. The purpose of this independent study is to study marketing mix that affect cinema purchase decision in Bangkok. The sample group of 400 was selected and the questionnaire was used as an instrument for data gathering. Statistics used for analysis included Percentage Mean Standard Deviation t-test one-way ANOVA least significant difference: LSD of 0.05 level and Multiple Regression. The results of this study show that most sample group are female who had bachelor degree age between 26-30 years old work for private employees and earn 20001-25000 THB per month. Overall group rated marketing mix factors at the high level. When considering each aspect the sample group paid highest attention to place followed by price product and promotion. Hypothesis testing found that there is differences in demographic factors which are age occupation and income affect purchase decision. On the other hand there is no differences of demographic factors in gender and education. In addition the results reveal that the marketing mix factors affect on purchase decision are product place promotion but not price.
