As Financial Knowledge based on Financial Risk Taking: The effects of financial literacy on risk tolerance has been concerned the objectives of this study are to compare levels of perceived risk and levels of financial literacy between two groups which are one who are likely to be good at financial literacy and one who do not and to analyze these linear relationships. This study is a survey research which the research methodology is mixed method. The qualitative data were collected from in-dept interview questionnaire while the quantitative data were also collected from online survey questionnaire. The population is students who enrolled in Bachelor of Business Administration in two main groups which are one who do and do not have financial literacy. The sample is students who enrolled in Department of Finance which represent one who have financial literacy and students who enrolled in Department of Information Technology which represent one who do not have financial literacy. The selection method of the sample is a purposive sampling method which surveyed fundamental financial knowledge financial behavior and perceived risk. The survey method used online survey and constructed in-depth interview. The sample were divided into three groups according to their perceived risks which are risk lovers risk neutral and risk averse. The hypothesis of this study is that there are differences between financial knowledge between sample who assessed their perceived risk themselves and who did them using a survey assessment. The results can be concluded that the population mean between two independent samples is statistically significant at level of 0.10 significance and the population mean between two groups of different methods of perceived risks is statistically significant of differences between those two means at 0.01 significance. Moreover the linear relationship which is correlation of financial literacy and perceived risk self-assessment is 0.175 (0.013) while one which is of financial literacy and perceived risk assessed by a survey is 0.160 (0.023). Thus these hypotheses are statistically significant. The suggestions are 1)financial curriculum should take a course of risk and risk management 2)investors who do not have good in financial knowledge should concern more about their investment including risk 3) investment consultant should assess the risk and perceived risk of consultee and let them know about the risks before making a investment decision 4)government should promote financial knowledge of financial planning cash management and investment allocation and risk diversification.

The objectives of this research are to study the rate of deterioration of tyre friction coefficient and investigate the quality of new and old tyres that are currently in use. A set of the rolling resistance testing was designed and set up to work with the single dynamometer according to speed 80 km/h tire load 4660 N and inflation pressure 30 psi. There were three tire samples new tire one year used tire and two year used tire to find the rolling resistance coefficients. The finding shows that the rolling resistance was inverse variation with tire aging. For instance the new tire (1st sample) had the highest rolling resistance on the other hand the two year used tire (3th sample) had the lowest rolling resistance. Moreover the rolling resistance coefficients were inverses variation with tire aging. Besides the one year used tire had the average of the decreasing rate of the rolling resistance coefficient at 0.03689 N/kN per a week while the two year had the average of the decreasing rate of the rolling resistance coefficient at 0.03671 N/kN per a week. Furthermore the result also revealed that the rolling resistance coefficients nonlinearly decreased comparing to the tire aging.

The research objective is to study the relationship between environmental disclosure levels corporate governance and the performance of companies listed in the Real Estate and Construction group on the Stock Exchange of Thailand. It was conducted by collecting information from the financial statements the annual reports and the information registration forms (Form 56-1) of 91 companies from 2015 to 2019. Descriptive statistics and inferential statistics were used in data analysis including correlation analysis and multiple regression analysis. The study results showed that environmental disclosure levels including environmental policy disclosure and other environmental disclosures positively correlate with the rate of return on equity return on total assets with a statistical significance at 0.01 and 0.05 levels. Corporate governance including the percentage of shareholding by the management and the number of the Board of Directors positively correlates with the return on total assets with a statistical significance at 0.01 and 0.05 levels.

Scholarship Website Project Faculty of Science and Technology Is a website developed to meet the needs of personnel and students.

This research aimed to study the relationship between financial ratios of operating efficiency and profitability of listed companies on the Stock Exchange of Thailand. Data was collected from the financial statements of the real estate and construction groups from 2015 to 2019. The data were analyzed using descriptive statistics such as frequency percentage mean and standard deviation. The inferential statistics were Pearsons Correlation Coefficient and Multiple Regression Analysis. The results of the study found that 1. operating cash flow activities positively correlated with the return on asset 2. the debt to asset ratio was negatively correlated with the gross profit margin net profit margin return on asset and return on equity 3. average collection period was negatively correlated with the gross profit margin and net profit margin 4. inventory turnover had a negative correlation with the return on asset 5. the total asset turnover was positively correlated with the net profit margin return on asset and return on equity with the statistical significance at a level of 0.05.
