By variable the media exposure of tourist program the media exposure behavior relations the satisfaction and the most satisfaction of tourist program relations effect on travel decision-making behavior.

The study on credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon were aimed to investigate1) personal factors of support staffs at Rajamangala University of Technology Phra Nakhon 2) credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon and 3)The relationship between personal factors and credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon. The instrument used to collect data was a questionnaire; and the sample group in the study was 260support staffs working at Rajamangala University of Technology Phra Nakhon. To analyze data descriptive statistics including frequency percentages and cross-tabulation distributions were applied. The hypotheses were that personal factors were related with credit card usage behavior of support staffs at Rajamangala University of Technology Phra Nakhon. The results revealed that the support staffs at Rajamangala University of Technology Phra Nakhon were between 30 to 39 years old. They held bachelors degrees and worked as the university employees. They were single who earned total income per month of 20001 - 30000 baht. There were 2 - 3 members in the family and had been working for over 5 years. Most of support staffs at Rajamangala University of Technology Phra Nakhon had 1- 2 credit cards with the duration of 2-3 years. The credit card limit was 20000 - 39999 baht. The type of the credit card was Visa card and the amount of monthly credit card spending was 2001 - 5000 baht. Regular cards used were issued by Krung Thai Bank (KTC). The value of goods or services for each spending was 1001 - 3000 baht at the most. Types of products or services that credit cards were used regularly were daily life products. The reason for using a credit card was its convenience for paying for goods or services (cash carried reduction). The channels to receive news that attracted applicants for credit cards were from bank employees and the opportunity to use credit cards to receive reward points to redeem discounts and prizes. Channels of spending via credit cards were through automatic credit approval machines with the frequency of spending of 1 - 3 times per month to pay for goods and services and installment payment for products and services on a periodic basis. The hypothesis test results disclosed that personal factors of the support staffs of Rajamangala University of Technology Phra Nakhon had a relationship with credit card usage behavior the bank cards regularly used the value of goods or services for each use and the opportunity to use credit cards.

The objective of this research is to study the combustion behavior of a gas-saving burner S-10 using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. LPG pressure of 4 psi was released for this study. The combustion behavior was shown in temperature contour and velocity vector. The CFD results were verified by measuring the temperature around the burner head with a vessel. From the study it was found that the CFD’s results of flow velocity and combustion temperature distributions were validated with the experimental values. The CFD’s result errors were less than 10.35% and 11.87% comparing with the velocity and temperature measurement respectively. The fluid flow and combustion behaviors can be described by this CFD model. Moreover the CFD model of the gas-saving burner S-10 can be applied to improve the thermal efficiency of the burner in the future.

The objective of this research is to study the combustion characteristic of a low-pressure vertical port burner using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. The CFD results were verified by measuring the temperature around the burner head and a vessel. Moreover the results of conventional vertical port burner having the swirl angle of 90o and the inclination angle of 90o (CB-S90I90) and two swirl port burners (SB) being SB-S90I13 and SB-S30I90 were compared. The temperatures obtained from CFD and experiments were similar which the error was less than 9%. From the CFD’s results the temperature and heat flux of the SB-S90I13 burner were higher than those of the CB-S90I90 burner. The maximum temperature and heat flux of SB-S90I13 burner were 1445 K and 5291 W/m2 respectively. It was implied that the combustion characteristic and heat transfer to the vessel of SB-S90I13 burner was better than that of CB-S90I90 burner. It was resulted that the thermal efficiency of SB-S90I13 burner was better than that of CB-S90I90 burner which was the percentage energy saving of 6.93%.

The Objectives of the study were to study the tourists social media exposure and their knowledge and attitudes towards cultural tourism in Bangkok Metropolitan. This research was quantitative methodology. The sample consisted of 400 tourists in Bangkok Metropolitan and used non-probability sampling by accidental random sampling. Data were collected through a questionnaire as the research instrument. The results of this study showed as follows: In terms of basic information the sample mostly travels with a family. The source of information were relatives friends acquaintances who have traveled to that location. In terms of exposure to social network the sample mostly exposed to social media via Facebook short messages via twitter online video via YouTube photo sharing via Instagram website via Wikipedia and Webboard via Pantip. The sample exposed to social media average of 1 hour during 1.00-6.59 pm. on a smartphone. The majority of the sample used social media at home searching for cultural tourism information at a high level. The highest mean is finding transportation. The sample receives cultural tourism information at a high level. The highest mean is exposure to information about arts crafts sculpture traditions and festivals. The most trustworthy social media is Youtube. The social media influence had a high level because fulfilling objectives such as tourist attraction accommodations restaurants travel etc. In terms of knowledge the sample had a high level of knowledge of cultural tourism. The area with the highest level of knowledge was increasing the diversity of cultural tourism such as heritage tourism art tourism urban culture tourism rural culture tourism creative tourism and Thai local wisdom. In terms of attitudes overall the sample gave the highest priority is security.
