This research aimed to study the influence of P/E ratio and market capitalization on returns of the securities in the energy sector in the Stock Exchange of Thailand. In this research the researcher has studied and collected data from the closing prices of the securities in energy sector that are currently traded in the Stock Exchange of Thailand. From January 2015 to December 2019 from the Stock Exchange of Thailand 15 companies and used descriptive analysis mean and standard deviation to test the relationship between independent variables by using correlation analysis and multiple regression analysis to determine the influence of P/E ratio and market capitalization on returns of the securities in the energy sector. The results of the research showed that the P/E ratio had a significant positive influence on returns of the energy securities in the Stock Exchange of Thailand. The market capitalization factor also found that it had no influence on returns of the energy securities in the Stock Exchange of Thailand.

This research aims to study the demographic characteristics affecting the decision to buy home furniture through mobile applications for Gen Y consumers and study the marketing mix 7 P’s and digital marketing model that affect the decision to buy home furniture through mobile application of Gen Y consumers. The population used in this research is population born between 1980 and 1997 are now between 24-41 years old live in Bangkok amount of 1453477 people the data were collected from 400 samples. The sample size was calculated following the Taro Yamane method.The descriptive statistics used were frequency percentage mean standard deviation (SD) and Inference statistical such as the difference analysis of the mean of the 2 sample groups (Independent Sample T-test) difference analysis for sample mean of more than 2 groups by one-way analysis of variance (One-Way ANOVA) and multiple regression analysis (Multiple Regression). The research results indicated that 1) the demographic characteristics such as gender and age had no impact on the overall decision-making to buy home furniture through mobile application of Gen Y consumers. In contrast marital status level of education career and income had an overall effect on the decision to buy home furniture through mobile applications for Gen Y consumers 2) Furthermore the marketing mix 7 P’s consisting of product price promotion process physica presentation and digital model on the overall effect the decision-making to buy home furniture through mobile applications. Moreover digital marketing model content marketing website creation assisted marketing e-mail marketing and online marketing impact the decision-making of buying home furniture through a mobile application. It was recommended that since the marketing mix especially product price and promotion affected the overall decision-making of buying product. Therefore if home furnitures are sold through mobile application content marketing must be developed at the highest level followed by social media marketing and email marketing had the most negligible positive impact on the overall buying decision-making and every factors

The purposes of this research are to study the causal relationship model about the influence of social responsibility on corporate image and brand loyalty of bird’s nest industry and to verify the consistency of the model with empirical data. 352 samples are the consumers of bird’s nest product who live or work in Bangkok. The research tools include questionnaire Statistical Package for the Social Science for Windows Program for statistical analysis and Linear Structural Relationship Model for analyzing causal relationship model. The result shows that the model of the influence of social responsibility on corporate image and brand loyalty of bird’s nest industry is consistent with empirical data considered by the chi-square statistics = 18.86 df = 11 p–value = 0.06 GFI = 0.99 AGFI = 0.95 SRMR = 0.021 RMSEA = 0.045. All variables in the model indicate that the variance of the brand loyalty of bird’s nest industry is at 77%. The social responsibility has a positive direct influence on the brand loyalty and indirect influence on the corporate image. Moreover the corporate image directly influences the brand loyalty. The result indicates that positive social responsibility makes good corporate image and it resulted in brand loyalty.

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%.

In spite of the copyright law in Thailand where distributing or obtaining a copyrighted work without the permission of the copyright holder is against the law illegal streaming and downloading of music is dramatically increasing. This changing behaviour of consumers has an incredible impact on the music industry as a whole. Our paper analyses the influence of intellectual property infringement on Thailand’s music industry income. The research tools employed in this study are a questionnaire and an in-depth interview to enable analysis. We found that after the evolution of musical technology in the 1990s internet-based music consumption has become significantly more popular and increasingly consumers are streaming sharing and discovering digital music all across the globe including in Thailand. With this new development of digital music the dynamics of the music industry have been affected significantly both in terms of income and number of entrepreneurs. Multiple regression analysis results show that the amount of unauthorized downloading of copyrighted music has a negative effect on Thailand’s music industry income. In contrast the number of property disputes from illegal downloading of copyrighted music has a positive effect on this industry income. The results suggest that entrepreneurs should pay attention to warranty information on products and prices and security of financial transactions in order to encourage consumer authorized online purchasing. In addition law enforcement can help achieve the goal of decreasing online music piracy.
