The Advanced Science and Technology and Products Exhibition-2025 took place at the Grand People’s Study House in Pyongyang from November 18 to 28.

On display there were mainly technologies and products highly appreciated at national festival of science and technology and sectional exhibitions of sci-tech successes held this year and other sci-tech research achievements recognized as advanced technologies in relevant fields and relevant products.

“This year much more units took part in the exhibition than last year. This shows how much the public is interested in increasing scientific and technical force and aspires for advanced things,” said Han Yong Jin, head of an office of the Grand People’s Study House.

The exhibition was attended by more than 550 units in different sectors including metal, chemical and machine-building industries, agriculture, light industry, public health, education and information industry. Presented there were more than 800 achievements in the research into advanced science and technology and more than 1 600 products.

The advanced sci-tech products presented by scientific research units, ministries and national agencies brought visitors greater pride in the technology and strength of the country.

The State Academy of Sciences presented the technologies of producing crystal thenardite, sodium carbonate and ammonium sulphate fertilizer with glauberite as a starting material and the method of controlling the quantity of pulverized coal fed into Juche iron rotary kiln using a zirconia waste gas oxygen analyser, which drew the attention of officials and experts in the relevant sector as they are of great economic significance.

The technology of producing hard alloy jointly developed by the mining industry research institute of the Ministry of Mining Industry and another unit and the rotary kiln slagging technology of the Tanchon Smeltery were also appreciated as ensuring high economic effectiveness.

The booths of the public health sector displaying products amazingly effective in treatment and health management were also crowded with people.

A household treatment device using polarized light presented by a unit improves blood circulation and cellular metabolism and decreases proliferation of viruses and malignant cells to perform the remarkable function of killing pain and treating inflammation merely with the irradiation of polarized light.

Visitors were fairly interested in peptide nutritive solution, which is highly effective against softening of the brain.

Brain softening, which is caused by carbon monoxide poisoning and surgical injury, means brain cell necrosis. It is not low in incidence and is regarded as the incurable among cerebral nerve diseases. After 20 years of painstaking research, the researchers found out that glucose-6-phosphatase can effectively treat the nutrient circulatory failure of the brain cells, the cause of necrosis, and facilitated the peptide bond of it to produce a nutritive solution. The peptide nutritive solution which ensures the rate of recovery by more than 90 percent attracted the attention of experts and visitors for its innovative treatment of softening of the brain.

Also popular with visitors were a boletus polysaccharide capsule which is highly effective in improving the immunopotency of the human body, retarding aging, preventing and treating cancerous diseases and treating diseases of the cardiovascular system and central nervous system, a trepang gelatine blood-making pill which acts as unique hematonic and is markedly effective in skin care, and an active nutrition pill which helps children grow tall.

During the exhibition there were also meetings for the transfer of technology and technical service in terms of advanced science and technology and products.
