This research was aimed to analyze work performance classified by personal information to investigate internal factors of support personnel work performance and influence of internal factors affecting work performance of the support personnel at Rajamangala University of Technology Phra Nakhon. The population used in this study was 693 staff working at Rajamangala University of Technology Phra Nakhon Bangkok. The sample size was determined by Craig and Morgan method to draw out 250 samples. The research instrument was a questionnaire constructed by the researcher to collect data manually. The data obtained from the questionnaire were analyzed using percentage mean standard deviation and T-test F-test ANOVA Pearson coefficient and multiple regression analysis. The research revealed the results as follows. Work performance of the support personnel of Rajamangala University of Technology Phra Nakhon in the overall was at high level with the mean Organization factors of the support personnel of Rajamangala University of Technology Phra Nakhon in the overall was at high level with the The results of the study on personal factors agreed with the overall performance of Rajamangala University of Technology Phra Nakhon personnel. It was found that the status salary and educationhours and working centers were significantly different .

The objective of this research is to study the suitable factor level for the improvement of annealing furnace for rolled coils steel sheet. The experimenting has been performed to find suitable oxygen level by 5 annealing furnace experiment. The research has been started by collection the combustion. After that the burning adjustment by changing combustion technology with 5 levels of BGCV control valve open as 23% 40% 50% 75% and 100% has been implemented. The combustion adjustment data are recorded analyzed and compared with incomplete combustion value. The research result has been found that after improvement the combustion value. The percentage of oxygen level are improved to the better quality which standard at MV0-49% equal 2.5-4 O2% and MV50-100% equal 1.5-2.5 O2% conclusion 1 furnace as follows at the MV23.1% MV40% MV50% MV75% and MV100% level of oxygen as 2.5% 3% 3% 2% 1.5% and level of carbon monoxide as 0 ppm 2 ppm 2 ppm 2 ppm and 0 ppm respectively. Resulting of fuel energy consumption in the annealing process has been reduced around 225608 baht /year/furnace. Therefore it can depict that energy saving and annealing furnace efficiency improving are increased. The modified parameters will be applied to be the new standard reference values for the further engineer’s operational manual.

This research aimed to study the factors affecting return of gold futures in Thailand futures exchange. The study used the daily historical data of five years from January 1 2011 - December 31 2015. There were five factors to be used in the study. They were Interbank Rate Set Index Exchange World Crude Oil Price and Gold Price and Used the Descriptive statistics to test the basic data and the Multiple Regression Analysis to test the hypothesis. The study found that the Interbank Rate Set Index Exchange Rate World Crude Oil Price and Gold Price were able to forecast the Coefficient of Determination (R2) approximately at 0.617. It showed that the independent variables in the model could explain the change of dependent variable at 61.70% and found that the most affecting factors on return of gold futures were Gold Price and Interbank rate by having the same directional relationship with the return of the Gold Futures in the Thailand Futures Exchange.

The objectives of the research were; 1) to Study the level of competitive advantage and 2) the factors that its influences through the competitive advantage. The population and sample group used in this research were an executive director owner manager general manager and the chief accountant and finance of 3-5 star hotels and resorts in Phuket by using questionnaire (IOC tested) the construct validity and reliability for 89 complete questionnaire that it was responded rate 23.18. The results of this investigation were as follows: 1) An efficiency of using asset to make a profit; Impact of competitive environment was found that the negative result in significant level at (α˂0.10). 2) Customer loyalty for products and services was found that the positive influencing factors such as good corporate governance at (α˂0.01); strategic management efficiency at (α˂0.01); and Internal controls effective following COSO at (α˂0.10) respectively. 3) Reputation of the business was found that the Positive influencing factors such as Internal controls effective following COSO (α ˂ 0.01); Good corporate governance and Strategic management efficiency at (α ˂ 0.05). and 4) Value of assets that value added to business was found that the positive influencing factors as well as Strategic management efficiency; Internal controls effective following COSO respectively in statistically significant level at (α ˂ 0.01). While the technology and innovation (α˂0.05) and good corporate governance positive that made the influences beyond the positive regression in statistically significant level at (α ˂ 0.10) respectively. Keywords : Competitive Advantage; Internal Controls Effective following COSO; Strategic Management Efficiency; Impacet of Competitive Environment; Good Corporate Governance; and Technology and Innovation

The objective of this research was to analyze determinants of nonperforming loans (NPLs) in commercial banking industry of Thailand during 2005 and 2014. This study used quarterly secondary data from the 1st quarter 2005 to the 4th quarter 2014 totaling 40 quarters. Descriptive statistics for testing data and econometric method for analyzing equation and multiple regression analysis for testing the hypothesis were used. The results of this research showed that the nonperforming loans (NPLs) in commercial banking industry of Thailand was positively related to the size of commercial bank with a confidence level of 95%but negatively related to consumer price index and prime rate with a confidence level of 95%. Loan-to-deposit ratio gross domestic product and loan volume were not related to NPLs.
