남북한이 평화적인 통일을 하려면 북한이 자력에 의하여 대한민국 수준으로 국민소득을 높여야 한다. 어느 일방에 의한 통일은 "대재앙"으로 표현 할 수 있다. 북한의 경제력을 대한민국 수준으로 올리려면 김정일 국방위원장의 교시대로 "담박도약"을 위해서는 개방과 더불어 IT산업으로 국가산업 발전에 역량을 모아야 한다. 북한도 IT산업을 통한 개방으로 유럽의 아일랜드와 같이 IT산업에 집중 할 것을 권유한다. 본 논문에서는 북한 SW개발자들이 개발한 부문을 분석하고 대한민국의 개발자들과 공동노력하여 발전 할 부문의 SW제품에 대하여 조사분석하였다.

Recently, heat resistant super alloys (which are wear-resistant, corrosion-resistant, and heat-resistant), have been used as the basic structural material in offshore and petrochemical plants. On the other hand, making valves from very expensive, high heat-resistant alloys increases the production cost and decreases its market competitiveness. To solve these problems, the technique of overlaying only those that flow on the fluid has been used as an effective method. Nevertheless, because the former technique of overlaying the ball is performed manually, it takes too much time and perfect welding is difficult to perform. To solve this problem, this study developed a robot automation system that can make uniformly overlay welding of the ball for ball-valves. The system consists of a 6-axis welding robot with a welding torch and additional 2 axes for the rotation of positioner, the controller, and a robot path OLP (Off-Line Programming). The CAD drawing data was entered in the Off-line program to obtain the robot teaching point and drive source. Overlay welding paths were implemented using Matlab. Through an automated overlaying system that implemented the OLP, the productivity rose 2.58 times, as the amount of time required for work decreased from 88 hours to 41 hours.
