Word spacing

[paekdusan]

How strict is word spacing in Korean?

Here's why I ask. It seems to me that spacing differs from source to source -- a handwritten letter, a newspaper article, a textbook.

For example, are any of these more correct than the other? The underlines [_] have been added to emphasize the spacing that I'm talking about.

가) 들어갈수없어요. ( )
나) 들어갈_수_ 없어요. ( )

가) 목요일 네시에 모인대. ( )
나) 몰요일 네_시에 모인대. ( )

가) 다른 사람에게 부탁하지않고 적접해결해요. ( )
니) 다른 사람에게 부탁하지_ 않고 적접_해결해요. ( )

Thanks in advance!

There would be no problem with the understanding.
But you may be considered as a less-educated person if you don't use correct spacing.

Ummm... but which ones are correct? The ones with more spacing or less spacing?
