Song Sun Yong, 76, living in Taedonggang District and Song Sun Ok in Pothonggang District in Pyongyang are sisters.
Song Sun Yong, an economist, worked as a leading official in the agricultural sector. After her retirement, she always thought how to boost agricultural production so as to improve the people’s living standards and finally started research in a unit.
She contributed to introducing a microbial farming method by developing various decomposing bacteria and composite lactic acid bacteria.
Later, she developed a biochemical, which made it possible to produce 1 to 3tons of crops even in the low-yielding fields. It was awarded a patent in May Juche 98 (2009). She rendered a great service in increasing grain production of the country by introducing it into hundreds of farms in Sinchon and Jaeryong counties in South Hwanghae Province, Migok-ri in Sariwon City in North Hwanghae Province and Pakchon County in North Phyongan Province.
She also developed natural functional products by making use of black pearl, which are helpful to improving the people’s health.
For the past 20 years she has won certificates, medals and diplomas in the national inventions exhibitions and national exhibitions of inventions and new technologies over ten times.
Song Sun Ok, 72, PhD. and associate professor, has been teaching at Pyongyang Teachers Training College for five decades after graduation from the then Pyongyang University of Education in August Juche 61 (1972).
In those days, she has presented valuable papers including “Study on Education Contents and Methods of Korean Language in Primary School”, pioneered several subjects and created new teaching methods for raising teaching practical activity.
She participated in editing Korean language textbook (from the first to the fifth grades of the primary school) when the country switched the universal 11-year compulsory education over to the universal 12-year compulsory education.
She visualizes the bright future of the country at the sight of her disciples teaching children in primary schools and kindergartens in the city and their pupils entering the university.
