국제인쇄산업대전 - "한국 인쇄산업의 동향과 수출전략"
김남수,Kim, Nam-Su 대한인쇄문화협회 2011 프린팅코리아 Vol.10 No.11
한국인쇄산업은 전반적으로 외형의 감소세를 보이고 있다. 이는 수년째 사업체수 및 종사자수가 감소한데 따른 것이다. 이에 비해 인쇄시설의 고급화와 IT시대를 맞아 자연스러운 구조조정이 진행된 결과로 출하액과 부가가치는 지속적인 증가세를 보이고 있다. 국제인쇄포럼에서 김남수 대한인쇄문화협회 회장이 발표한 내용을 요약 정리한다.

Experimental investigations have been carried out to find the effect of drag reduction caused by effective polymer additives in turbulent flows. The experiments were undertaken with a test section of 9.8mm pipe diameter and 3500 mm pipe length(L/D=357) in a closed loop, and Copolymer-X and Polyacrylamide(PAAM) were used as polymer additives for comparisons. The tests were carried out under different polymer concentrations, and the temperatures of the flow considered were $26^{\circ}C$, $60^{\circ}C$ at the flow velocity of 5.3 m/s. The rate of drag reduction obtained by Copolymer-X is found to be considerably higher than that of PAAM in turbulent flows. Copolymer-X is also found to be very reliable for mechanical degradation, which has not been the case in any other additives. It is concluded that Copolymer-X is considered to be one of the most effective agents as an additive especially for long time hydraulic transports. It is also found that polymer degradation in more likely at lower polymer concentrations in the turbulent flows.

With the Knowledge informatization in 21C, it is expected to change globally in our society. but we are not faced with that change effectively. By way of newspaper, it has been known that our country is the strongest information power through the Internet. But in fact, it is known that it is not in its contents. We have invested a lot in achieving the information society for a nation's high competition. We have been ahead of other country in having the high-speed network facilities for a high infra-structures. And it should develop not only an individual's innovaton but also various contents necessary to manage its informatization. But it is still lack in it. In our study, I investigated the problems & perceptions of a public servant. I have known that our education for a public servant is not well-done systematically by the individual's ability, functions, orders. Now we should teach and study information education more systematically. It has still remained in teaching the basic computer skills- word processor, Excel, PPT and so on. In the future, Computer education curriculm shoud be divided into a basic level class, middle level class, and a high level class in order to develop computer programs and be able to do these tasks for yourself.
