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.

The purposes of this research are 1) to study the demographic characteristics and behavior in purchasing via line application and 2) to compare the level of satisfaction in purchasing via line application for an open chat consumer group Kheha Thanee 4 Village Bangkok. This study applied quantitative methods and the research instrument was an online questionnaire. The sample group of this study consisted of 306 consumers members of the open chat consumer group Kheha Thanee 4 Village Bangkok. The data were analyzed by frequency percentage mean standard deviation and the researcher tested hypothesis with T Test and One Way ANOVA. The research findings were as follows:

This research aims to study the personal factors. Behavior and Marketing Communications on the behavior of the History tour of tourists in Bangkok Thailand. The hybrid research Is Quantitative Research 400 samples. Questionnaires were used to collect data. The statistics used in the analysis were percentage mean standard deviation. Chi-square test the level of statistical significance .05. And Qualitative Research In-depth interviews in finding consensus and conflict between management Museum. Marketers Museum Visitors to the museum and the results of quantitative research. The results showed that: 1) Most of the respondents aged 15-25 years old single female student with a bachelors degree. The average income per person is not more than 7000 baht monthly income of an average family 15000-30000 baht and living in Bangkok. 2) Most of the planned tour. Most holiday weekend. The main objective is to study the first year of the museum tour 1-2 times a tourism model is geared experience. Each tour takes 2-3 hours. 3) Behavioral marketing communications planning travel. Time to travel the main purpose of tourism the number of times in one year tourism model. The level of significance. 05. The results of the research showed. The most consistent hypothesis testing with quantitative research. Keywords : Marketing Communications Travel habits History Museum

The objectives of this research were to study personal factors and cat product consumer behavior. To study marketing mix factors related to customer behavior included marketing mix factor related to cat product consumer behavior in Thailand metropolis. This research was combined 2 methods. Quantitative research: The samples were 400 consumers by using questionnaire as tool to collected data. Analyzed by using descriptive statistics to determine frequency percentage mean standard deviation Pearsons chi-squared test statistics on the statistical level significance of .05. And Quality research: The sample are opinion leader vendor and consumer by using Indepth interview to analyze relation between opinion vender and consumer conform to result of quantitative research. The research results revealed as follow: 1) Majority of the samples were female age between 31-35 years old single status tropically had bachelors degree average monthly income level 20001-30000 Baht per month own only one cat main reason for taking care cat to make friend. 2) Majority of the samples were focus on the quality of the cat product. Frequency of purchasing few times per week. Spend more than 500 baht per time. Decission making by themselves. The quatity of purchasing are uncertainty depend on the convenience and purchasing by themselves.
