During my time at Mahidol University. I have used a variety of methods in different research and analysis applications in the environmental work that may be harmful to employee. For example, using Microsoft excel to compare results in an increase of accidents of employee in each year, using Microsoft word and Power point presentation for an overview of research and the importance of research. In addition, when I was working at Thai Ability Engineering, I offered advice on how to increase the security management in factories must comply with safety regulations. I controlled to improve security and eliminated the obstacles to the employee's working conditions.
