By the scene on the floor of the South Korean Parliament,帮忙翻译!

By the scene on the floor of the South Korean Parliament, hundreds of lawmakers and their aides scuffled Wednesday after the ruling party had to railroad a set of bills on media ownership.

我先来翻译一下:
目睹在统治党不得不草率通过一组关于媒体所有权的议案之后,周三,南韩议会的议会席上,成百名立法者和他们的助手展开了一场混战.

不知道对不对,请大家指教!
另外我想问一下,floor是议会席的意思嘛?还有如果Wednesday作为周三解释,为什么没有介词on?
谢谢!
