Universities and colleges in all parts of the Democratic People's Republic of Korea are working hard to solve the problems arising in reality.

Teachers and researchers of Kim Il Sung University developed a sealing ring whose serviceable life is more than 2.5 times as against before by introducing advanced technology, making a contribution to normalizing the fertilizer production at the Namhung Youth Chemical Complex and the Hungnam Fertilizer Complex.

Kim Chaek University of Technology developed a dry-type dust collector increasing the pig iron production while extremely reducing the anthracite and oxygen consumption and introduced it into the oxygen-blast furnaces of Kim Chaek and Hwanghae iron and steel complexes.

The Pyongyang University of Transport and the Pyongyang University of Publishing and Printing Industry developed a comprehensive system of controlling the traction and braking forces of electric locomotives and a school bag decoration printing process by ink jet, enabling those units that introduced them to save the production costs by far.

Teachers at the Sunchon College of Engineering developed a plotter which can do the pattern making, the preceding process of the garment production, automatically.
