I think the Korean translation above is a little bit literal one, this is my one.

Answer

I agree with this comment.

"As" is translated as "..(할) 때" or "..(하)면서" not very often as "동안".

"동안" corresponds more to "while" or "during".

Answer

meaning as : when , during

I think the "as" is using "when meaning"

in conclusion

그가 나무의자에 앉아 있었을때, 그는 창문을 통해 보았다.

보았다(looked through)  보고 있었다 (was looking through)
