I am currently studying Logistic System Engineering as my major which is related with some kind of distribution of materials.

Nowdays, logistic is a very necessary part of the trade as well as world commerce. I have a high interest in it and therefore, I believe it will be easy for me to find a job. :)
I like to read and I enjoy work out in gym. Both of these activities are very contrast however I enjoy it very much.

Firstly, I enjoy reading books which are Japenese novel as well as World Classic novel.As for exercise, working out in the gym and swimming. However, I am not very good in any kind of ball sports game. but I do enjoy watching soccer and baseball.

Thank you and that is all for my first introduction. 

I know I change alot and to be frank I am totally new at this. Hope you like my correction. ㅋㅋㅋ looking forward to communicate with you soon. 

First notebook entry: Introducing myself

Hello
I'm a University student in South Korea not North Korea.
I have a family of four and we all live together.
My major is logistic systems engineering which is related to some kinds of distribution of materials.
Nowdays logistics is very a necessary part of the trade and world commerce so I think this is a good benefit for finding a job. :)
Also I have interest in the subject too.
I like reading books and working out at the gym.
These hobbies are of very contrasting areas but I like both. 
first I like reading books such as japanese novels and classic novels from around the world.
Second I like to exercise by working out in the gym or swimming in the pool because I'm not good at ball related sports games.  I like just watching that sports like soccer and baseball.
Thank you. that's all of my first introduction to somebody.
Maybe there are so many gramatical and spelling mistakes in the upper above writing. please check my note.

Not a bad start.  Hopefully these corrections will be helpful.  I just corrected your writing to what sounds most natural to me.  Your grammar needs to improve but I could understand what you were trying to communicate and that is the most important part!  Good job.   Also I sent you a follow with a link to and english website...that was accidental!  Sorry I meant to include a message about langauge exchange but was not able to correct it.
