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. Is it not 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 a 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 to me that most people are thinking that moving forward only is the best way to construct the future for humans.

Although the term technology is new and being up-to-date is also important, some- times it appears that the quality perspective of such high-tech equipment cannot be ignored. Especially, about the way the equipment is created in how appropriate and rational thought.

We, Sejong Engineering Co., Ltd are devoting our full attention to only the engineering and the construction supervision within the electricity industry since the foundation in 1985 until today. At present, we have no doubt that our work is contributing to the national development including electric train, urban railway, light rail, harbour con- struction, express way, plant industries and more.

I believe this is all because of the hard work of all of our executives and staff members who did not spared no effort but only gave their devotion. I also believe that I have come this far because of the many elders around me who did not spare any love or guidance, and I appreciate their help 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.
