particles - using の with と,で, から, まで

http://www.shiro.jp.net/2013/10/tono-deno-kakrano-madenoeno-learning.html

This page explains that a noun with と, で, から, まで that modifies another noun must have の attached to them as in:

日本での研究はいかがでしたか。

But it lists this example

大学院で医学の研究をするつもりです。

Both with で. what is the difference between them? Are there other rules about の and と, で, から, まで, etc?

Answer

The difference is that での shows the relationship to a following noun, just as the page says. 日本での研究 forms a single noun phrase ("research in Japan"), and this noun phrase as a whole is marked as a topic with は.

In the other example, 大学院で isn't part of a noun phrase. Instead, it modifies the following predicate, （医学の研究を）する ("do medical research").

So it's just as the web page says. If you see ～での, you should be figuring out what noun it links to (研究), and if you see ～で, you should be figuring out what verb (or other predicate) it links to (する).
