Top scientists and technicians of 2022 have been chosen in the DPRK.

Kim Ryong Hung, candidate academician, professor, PhD and section chief of the resources science faculty of Kim Il Sung University

Kim Ryong Hung contributed greatly to establishing a salt production method based on underground ultra-saline water for the first time in the DPRK. He played a core role in carrying out a project related to the prospecting and intake technique of underground ultra-saline water resources.

It was a dozen years ago that he and other research group members had conceived a scientific idea that underground ultra-saline water resources exist in the country.

Chairman Kim Jong Il highly appreciated their idea related to underground ultra-saline water resources after getting familiar with their efforts on a visit to Kim Il Sung University in April 2010.

Since then, Kim Ryong Hung and other research group members have conducted research into underground ultra-saline water resources, thereby providing a precondition for prospecting the resources on the west coast of Korea, developing a high-performance prospecting machine and achieving significant research hits.

Jang Sung Jun, Merited Scientist, PhD and section chief of the heat engineering institute of the State Academy of Sciences

He played a leading role in researching and introducing the ignition and combustion stabilizing technology based on oxygen-pulverized coal.

He has been awarded the February 16 Science and Technology Prize on four occasions so far. He received three of the four prizes after carrying out research projects at the Pukchang Thermal Power Complex.

The road of research covered by him as a heat engineer for about 30 years can be claimed to be a way for putting an end to the history of relying on heavy oil in the thermal power sector. In the period of hard times, he introduced high-performance air type coal pulverizers into large-sized boilers in Pukchang, making it possible to save a large amount of heavy oil and coal and increase electricity production. He then made painstaking efforts to develop and apply a heavy oil-free oxygen-pulverized coal ignition device by breaking the existing idea that it was impossible with the Korean anthracite. He succeeded again in researching and introducing the ignition and combustion stabilizing technology based on oxygen-pulverized coal into a large-sized boiler at the Pukchang Thermal Power Complex.

Kim Chang Yu, Merited Scientist, PhD and section chief of the high-tech products exchange centre of Sariwon Kye Ung Sang University of Agriculture

He developed “Sinyang 2” compound bacteria, which is widely known throughout the agricultural sector, as well as the production technology of organic fertilizer by using the bacteria.

Since times of hardship, he had travelled all parts of the country to obtain compound bacteria, which can guarantee high effect in unfavourable environment by finding out organisms existing in the severe nature, and collect samples, thus separating at least 16 000 kinds of bacteria. He took great pains to make compound bacteria by selecting dozens of active bacteria one by one which had been acclimatized to the climatic and soil conditions of Korea.

The effect of one ton of organic fertilizer produced with the help of “Sinyang 2” compound bacteria is equivalent to that of 20 tons of ordinary compost. The compound bacteria are winning great favour as the days go by as they help remarkably increase per-hectare grain yield.

Ri Il Hun, PhD and section chief of the Oncology Institute of the Academy of Medical Sciences

He is a prestigious medical man in the sector of internal treatment of tumour who developed medicines for preventing the recurrence and metastasis of cancer and contributed to establishing the treatment methods of the incurable disease through decades-long clinical tests.

As he concentrated his effort on research into those medicines for many years, he developed such medicines by a bioengineering method and proved their security and effectiveness on a scientific and objective basis.

He established a treatment method capable of increasing the survival rate of cancer cases as compared to other cancer treatment methods and updated the standard of anti-cancer product and production process.

Hyon Ok Ju, MSc and chief of the heat-preserving building materials branch factory of the Pyongyang Thermal Power Station

She played a leading role in industrializing the production process of hollow soot insulating bricks using waste from thermal power stations for the first time and a technician who contributed greatly to boosting electricity production by establishing an air-tight and heat-preserving construction method of boiler firebox based on insulating bricks with great economic profits.

She was not an expert or technician who majored in materials or mechanical engineering sector. She boldly buckled down to the study of insulating bricks in order to present a creation which gives the country what little help she can give for the prosperity and development of the country.

The state awarded her the February 16 Science and Technology Prize in recognition of the feat of her who has invariably followed the road of quest for the increased production of electricity with fervent patriotism.
