That's a look at two moon bear cubs, from Yonhap. The JoongAng Daily has the story in English:
An Asiatic black bear, protected as endangered species in Korea, has given birth to two cubs on the Mount Jiri, the National Park Service said yesterday. It is the second time that the bear, known more commonly as a half-moon bear in Korea, gave birth after being released to the wild.
According to park authorities, researchers from the Species Restoration Center found the cubs and the mother on Feb. 23. The team made the discovery when the members visited a cave on the mountain.
The article goes on to talk about the effort started in 2004 to reintroduce these Asiatic Black Bears (반달가슴곰) back into the wild in Jirisan National Park (지리산국립공원), which spans three provinces including eastern Jeollanam-do. When Googling around for more information I realized I was the first Google search result, so here's the post I did last March, the last time cubs were born there. Actually that was the first time cubs were born on Jirisan without medical assistance.

You're unlikely to come across a moon bear while hiking Jirisan, and as a matter of fact it took a couple of years before anybody ever got a picture of one, back before they tried reintroducing them, that is.
As that post says, one obstacle to sustaining a population in the wild is that people still hunt them for food and medicine. The site MoonBears.org provides perspective on that. A post in November points to a JoongAng Daily article in October about Vietnamese urging Korean businesspeople and tourists not to engage in the bear trade in Vietnam:
Unlike in Vietnam, bear farming and the sale of bear bile is legal in Korea. In the 1980s, the Korean government made it legal to breed bears. It was a way to assist struggling local farmers as well as boost the population of moon bears, an endangered species. Some bears are raised for sightseeing activities, but most are destined to be killed for their organs, bile and meat.
These black bears were designated as Natural Monument #329 by the Cultural Heritage Administration of Korea on November 4th, 1982.
