[lafi05]

dear friends,

Now I am preparing essay and CV for my master. but I stucked.

I have experience on project in Occupational health almost 2 year, but I dont have any publication from this subject

beside that, I made own research and joined with my senior lecturer on environmental health science and our research have presented in several international conference.

I was from occupational health  safety 

department , and I love this science but Also,I love everything about environmental health science. 

In university where I will take master degree, occupational health safety and environmental health science are different. I have choose between them. 

it is so hard for me, it is just like choose johnny deep or leonardo dicaprio

what should I choose ? 

based on my experience, which experience will support me strongly to be accepted in master degree ?
