Thank you for the help!
Those are the two hangul syllables that are pronounced hangeul, and mean hangul. I don't understand the question.

I would need to consult my Korean typeface specimen books, which are in my office, but I am still at home. Clearly, it is a heavy sans serif design on which a shadow effect has been applied. We licensed a similar design from Hanyang in the 1990s, and the font is HYKakHeadlineStd-Bold. Here is a sample, using the same characters as shown above:

I checked my Korean typeface specimen books, and the typeface appears to be Hanyang's "HY Headline Bold," which is the non-squared version of HYKakHeadlineStd-Bold whose sample I provided above.

Well, at least that'll keep me off the streets... ;-)

I don't know if you need an exact match, but if you do, your sample isn't in HY Headline Bold (sample below, condensed to 90%), although it's certainly a similar style.

Most Korean foundries have their own versions of "Headline (헤드라인)" designs of this style, such as HY Headline, Rix Headline, etc. They may be offered in angled (gak, 각) or round (dunggeun, 둥근) versions, hence the HY Kak Headline, kak being an alternate romanization of 각.
"Headline" faces are also called jemok (제목) faces, so you may also have to look through some dunggeun jemok (둥근제목, round headline) faces offered by different foundries.
I haven't been able to find an exact match. It's not one of the usual suspects (Hanyang, Baekmuk, Sandoll, etc.) and I've exhausted the few specimens I have. Online samples are too small and most often don't include the glyphs "한글!". If you need an exact match, I can investigate further.
I've just realized where that sample is from:

It's from the Hoefler & Frere-Jones website.
