The Status of Korea’s R&D• The Korean government has sponsored national R&D

activities since 1982▫ The budget for science and engineering technology in

2009 was about 10 billion USD, 13.8% increased then 2008.

• As the amount of investment in national R&D projects increases▫ The science competitive power of Korea in the world con-

tinues to be enhanced and is in the group of 3 leading countries with the USA and Japan.

▫ In 2007, SCI paper rank was on the 12th place, international patents rank was on the 4th place in the

world

The Status of Higher Education in Science and Engi-neering

• The competitiveness of the national science and technol-ogy▫ Korea has been steadily improved and reached to the rank

of three in 2009 IMD(International Institute for Management Development) report, 2009

• The usefulness of the national education system▫ Totally different situation that the rank was the 36th in the

world• The reeducation cost for the newly graduates is so high

▫ The good research results have been hardly applied into the education.

▫ The higher education of science and engineering in Korea has been focused on the theory-based learning rather than experiment-based learning.

• How to solve these problems?▫ Experiment-based science and engineering education on the

cyber infrastructure is one of the possible solutions.

Future Directions for the Higher Education• The accomplishments from many R&D projects spon-

sored by the Korean government▫ can be used in science and technology education, the

education effect would be maximized without extra spending for purchasing expensive educational soft-ware.

• We have learned that ▫ performing the national scale development project on

computer simulation-based cyber research and educa-tion environment which is basically the expansion of such EDISON having various simulation related soft-wares, contents and tools is now inevitable.

• Mobile Environment▫ We also have to expand this system into mobile envi-

ronment accommodating such smart phones for riding the new huge tide.
