My apologize

As you can see, I have not blogged for a while. Actually, I had to participate in a required military training course last month, and although I expected to complete my assignment during that time, I could not have enough energy to focus on the e-course.

Now I am back home and read, watch all the material from the e-course. I will post all of my belated assignments at once. Hope that you guys will drop some comments. In fact, your work inspired me a lot to complete to course and to catch up with all of you!
