  • Since 1985, the growth rate of population of the world is over that of the food production. The cultivated land and the grain production rate are decreasing every year. Therefore, the most serious crisis which we will meet in the 21st century will be food shortage. In order to solve this desperate shortage of food, besides trying to produce more food, the technology of post-harvest, food processing, and food packaging should be developed to reduce and make the best use of the amount of the already produced agricultural products for which a lots of cost and labors were invested, but are being wasted during food distribution channel due to their undeveloped technology.

  • On 16Dec. 1999, It was 100 years since the opening the first railroad section of 33.2km on Sep. 1899, Korea High Speed Railroad had a successful trial run of 200km/h on test track section. And the test speed 300km/h was achieved an 28 June 2000 during continuous commissioning. In the 21st century, the High Speed Railroad will be opened commercially in Korea and will contribute to technical development. Now, it is necessary to re-evaluate the role of railroad in modern society and to activate the railroad system. Ultimately, the competitive power of nation will be strengthened with energy saving, reduction of pollution and transportation cost. It conclusion the railroad system have to be expaned about 50% of total transportation to make preparations for reopening of Eurasia silk route through KyungEu railroad connection.
