11F, 1st Hanhwa Bizmetro Bldg, 851 Guro 3 Dong, Guro-Gu, Seoul, Korea Tel +82.2.262.12345 Fax +82.2.262.12340 Although we are not the most advanced company, we will always welcome tomorrow in an exertive and researching attitude to become an enterprise that can give you the most trust.

We can say that a human life is about changes. Isn’t the case that the environment and the history of the earth are revolving like a spinning wheel because there are people thriving for a better place or for more efficient development?

Recently, words such as high-technology or first-rate are used in various places, and it is hard to properly foresee where the paths are leading to. However, it seems most people are thinking moving forward is the best way to construct the future for humans.

Although technology is new and being up-to-date is also important, sometimes it appears that how the equipment is created systematically in a appropriate and rational way cannot be ignored.

We, Sejong Engineering Co., Ltd., are devoting our full attention to the design and the supervision in the electrical business field since the foundation in 1985 until today. At present, we have no doubt that our work is contributing to the national development such as the electrical train, the urban railway, the light rail transit, harbour construc- tion, the express way, the plant industries and more.

I believe this is due to the hard work of all of our executives and staff members who did not spared any effort but only gave their devotion. I also believe that I have come to this far because of the many elders around me who did not spare their loves and guidance. I appreciate their helps all the time.

Although we are not the most advanced company, we will always welcome tomorrow in an exertive and researching attitude to become an enterprise that can give you the most trust.

Thank you.
