The youth technical innovation shock-brigade members at the Jangjingang Power Station made a protective device for power line, while those at the Namhung Youth Chemical Complex and Ryongsong Machine Complex played a leading role in solving the sci-tech problems.

Similar sci-tech achievements were also made by young people at the Soho Fishery Station under the South Hamgyong Provincial Fishery Management Bureau, the Institute of Antibiotics under the Academy of Medical Science and the Pyongyang Children's Foodstuff Factory.

The youth shock-brigades active at the Hamhung Knitwear Factory and the Kim Jong Thae Electric Locomotive Complex made contributions to the home-production of elastic cloth and to the establishment of a bed-grinding process.
