Yu devoted over a decade to in-depth analysis of more than 1 000 species of plants in order to find out plants suitable as substances for controlling blight and killing harmful insects.

At last she developed a biochemical Myongnok and was awarded the title of Merited Scientist in 2008.

Kang Song Ran, head of the Hochon County Commercial Agency in South Hamgyong Province, is well known across the county.

Since she was posted as the head of the agency in the mid-1990s, Kang made persevering and strenuous efforts to facelift all the commercial and service establishments in her county and improve their activities. Her efforts paid off.

She led her employees, although most of them were women, to create nearly 70-hectare raw material supply base and lay out solid foundations for animal husbandry. They also collected and processed scores of kinds of edible greens, including bracken and anise, and wild fruits every year and supplied them to the local people.

For the past decades they supplied dairy products they have produced by themselves to nursery and kindergarten children as well as schoolchildren across the county on a regular basis.

In recognition of what Kang has performed for the commercial development of the county, regarding the devotion to the people as her lifelong motto, the state put her forward as a meritorious person of socialist patriotism and Labour Hero of the DPRK.
