Textile CAD/CAM system researched and completed by the research group headed by Jong Il Chol, laboratory head of the Faculty of Automation Engineering, was introduced to light industry mills and enterprises that produce towels, blankets, fabrics and knitted goods, thus paying off.
After one year of painstaking research, they designed and manufactured the integrated control panel for loom and completed the textile CAD/CAM program that can provide various patterns according to requirements and that can control the looms.
And with the establishment of the integrated production system, they shortened the period of developing new product within one hour instead of 6 months, to say nothing of the economy in raw material, quality of goods and good productivity.

The research team led by Choe Song Il, director of Mirae Industrial Technology Institute, Ri Nam Chol, laboratory head of the Institute, developed high efficiency carboxylic acid system permeation crystal type concrete waterproof agent from their own technology and this is proving highly effective in green building materials industry.
This grey powdered waterproof agent is mixed with a certain amount of water and applied to concrete plastered wall and it yields waterproofing effects in two days. What’s of particular characteristics is its peculiar watertight quality that coexists with the lifespan of concrete. This agent permeates into concrete as deep as 100mm and develops needle crystals so that it forms a stable waterproof zone.

Research team led by Kim Kum Chol, the laboratory head from the Faculty of Electronics, developed various high-efficiency portable analyzers with self-technology and is gaining public favors from various fields of national economy.
Colon bacilli analyzer developed by the research team analyzes colon bacilli in water, whose measurement range is 0~1 000/mL, minimum disjointing capability is 1/mL. Toxic gas analyzer analyzes CO, CO2, SO2, NO2, O3, H2S etc. in the air and its measurement range is 0~1 000ppm, minimum disjointing capability is 0.1ppm, analyzing time is less than 10s. The measurement range of procedure saltiness gauge used in the analysis of saltiness for underground ultra-salty water, soya and bean paste production process of basic foodstuff factories, saltiness of seawater, boiler feed water etc. is 0~30%, minimum disjointing capability is 0.1ppm. Of turbidity analyzer, measurement range is 0~10NTU and minimum disjointing capability is 0.1NTU. They are now developing their research work for further enhancing the accuracy of their analyzers.
