A research group of head of the Physics Engineering Faculty developed the technology for measuring precisely the 3 dimension outline of the thing by means of the injection of the straight line laser and processing the value of co-ordinates with the computer so that they could make a great contribution to different aspects of the light industry and public healthcare and physics culture including clothing and shoes industry.
They devised the precise micro-vibrating apparatus which can inject the outline of the thing with the straight line laser and detect its light lines and also developed the 3-dimension producing program to get more correct outline of the thing. At present this research group is channeling a great effort to improving the accuracy of this technology.

The research team including Jang Chol Min, head of laboratory of Nano Physics Engineering Institute developed the gas-detecting transmitter and application technology of micro-bubble, and are building on its success.
They succeeded in developing the gas-detecting material which is capable of detecting quickly and precisely ammonia, hydrogen sulfide and carbon dioxide in the air and on the basis of this, they also developed the automatic gas-detecting transmitter which is capable of measuring and controlling the gas in the given building in real time by manufacturing the solid-state detector which has higher adaptability to environment, lasts longer and is much cheaper than an electrical and chemical way.
They also introduced the micro-bubble technology into purification of waste water so that they could speed up the disintegration of aerobic microorganism into organic materials, and created the reliable technical guarantee for discharging purified water by establishing the process of purifying waste water bio-chemically which can improve the average characteristic indices of water quality such as biochemical and chemical requirement for oxygen and ratio of removing ammonia nitrogen in comparison with the general porous plant by 10 or 20 % and decrease the consumption of electric power to less than 80 % by means of oxidization of organic polluting material which are impossible to decompose with radical ions generating micro-bubbles.
As a result of introduction in one stock-farm, this technology proved very efficient and economic.
In the future, fruitful will be their continuous research for applying it to various fields including purification of water as well as production of crops and vegetables, aquatic culture, IC cleansing, floriculture and preservation of freshness of fishes.

Pak Se Il and his research team of the Faculty of Heat Engineering succeeded in establishing the hot blast drying process for CMYK which is using electrically heated air.
They proposed to use electrically heated air instead of propane gas to dry the printing material in the CMYK hot blast offset duplicator and made clear the characteristics of drying printing material and the relationship of different elements which have influence on the quality and output of products and consumption of electricity of the printing material while they are dried.
They also designed the new heat switchboard which is capable of making an effective use of the heat of waste air at different temperatures of more than 110℃ giving off during the period of drying so that they could economize a large amount of energy needed in drying the printing material.
They constructed the control system in keeping with the operation conditions so that rational indices of the operation were determined which made it possible to establish the hot blast drying process using electrically heated air.

Ra Chung Yol and Cho Yong Yon, researchers from the Faculty of Resources Probing Engineering have developed white magnesia cement, green building material, from our own brucite marble, and greatly contributed to the industrialization.
Newly developed white magnesia cement can be produced in the existing process in the factory without establishing a new process and its pressure strength is42MPa.
As the burning temperature is 100~200℃ lower in comparison with dolomitecement and the range is between 400℃ and 700℃, it consumes less fuel andconvenient to produce. In particular the whiteness is over 88%, so it is far superior to another magnesia cement. Therefore, it is being used as good finishing building materials.
