In Competitive environment Information Technology applications have the potential to create competitive advantage. This study is attemp to explain the impact of the TOC and Information Technology in Operations management. With the application of the TOC Pricinples to Information Technology, it is easy to exploit efficiently industrial organizations' constraints and elevate its constaints. The objective of this study descrive a structure of TOC, necessity of Information technology, and alignment of TOC and Information Technology.

In this study we have provided one solution to overcome mistakes with limited technical staffs, capitals and times may be the computer for cost estimating. In view of the speed and the ability to draw on funds of information, we shall see that computer estimating models will become the exhibited and the accepted norm of operation by continuous research. Therefore, the computer is broadly serving the needs of many engineering disciplines and in the area of engineering design and industrial application, inexhaustible developed softwares are presented more easy speed and various application for Cost Engineering.

This paper deals with an industrial application of a fuzzy feedback combined learning control to an industrial batch free radical polymerization reactor. As a result, the plant has reduced the batch reaction time by 50 minute and stabilized both by 40 percent reduction of the standard deviations of product qualities, such as the total solid content and the graft gum, and by 45 percent reduction of the standard deviation of the batch reaction end time.

This paper is to present the general descriptions and their research trend of MRl/NMR which has already commercialized and also is more successful than any other applications of superconducting magnet, Superconducting Single Crystal Growing Equipment and Superconducting Magnetic Separation technology which are practically used in the related areas, and power electric application machine, which is the most effective and efficient one among the applications using high magnetic field. Therefore, it is hoped that this study will help to establish the ground of the industrial application of superconductivity in Korea.

This study presents an application of stochastic model for limit order book (LOB) dynamics to Korean Stock Index Futures (KOSPI 200 Futures). Since KOSPI 200 futures market is widely known as one of the most liquid markets in the world, direct application of an existing model is hardly possible. Therefore, we modified an existing model to successfully model and predict the dynamics of extremely liquid KOSPI 200 futures market.

36 percent nickel-iron alloy possesses a useful combination of low thermal expansion, moderately high strength and good toughness at temperatures down to that of liquid helium, $-269^{\circ}C$. These propeties coupled with good weldability and desirable physical properties make this alloy attractive for many cryogenic applications such as the cargo containment system in Liquefied Natural Gas carriers and pipes for low temperature. Generally, welding method of the 36% nickel-iron is applied with the manual and autogeneous GTAW. Lately white spots have been observed on the some autogeneous GTA welds of them. But the white spot formation have not been studied yet. This paper covers the analysis results of the white spots formation as changing welding variables.

최근 컨테이너선은 점차 대형화되고 있으며, 이에 따라 선체의 외판 상부의 철판 두께도 최대 80mm 까지 설계되고 있다. 블록 외판의 수직 맞대기 용접의 경우 고능률 용접기법인 Electro Gas Weldig(이하 EGW)이 적용되고 있으나, 극 후판의 경우, 기존의 한 개의 전극만으로는 적용 가능한 두께 범위의 한계가 있어 수직 맞대기 용접의 용접생산을 향상시키기 위해 2개의 전극을 사용하는 탄뎀 EGW 기법에 의한 시공법이 고려되었다. 탄뎀 EGW 기법의 시공법에 관한 보고서는 국내외에서 많이 발표되어져 왔다. 하지만 실선 적용에 있어 두께 80mm, 길이 2M 이상의 철판을 안정적으로 용접하기 위한 장애요소는 용접 중 적절한 슬래그의 배출 조절이다. 두개의 용접 와이어를 동시에 공급할 때 발생하는 슬래그를 균형있게 배출하지 못하는 경우 용융, 금속 상부에 적층되는 슬래그의 양이 증가하게 되고, 아크는 불안해져서 전극팁에의 슬래그 부착, 전극 팁의 발열 등에 의한 요인들이 송급을 불안하게 하여 연속 용접이 어려워진다. 본 연구에서는 탄뎀 EGW 기법을 실제로 현업에 적용하기 위해서는 안정적인 슬래그 배출에 착안하여 동당금의 형상에 따라 슬래그의 배출 성능을 확인하고 형상별 전류, 전압 파형을 측정하고, 파형 결과에 따라 아크 안정성을 평가함으로서 탄뎀 EGW 용접기법에 적정한 동당금을 설계한 결과를 소개하고자 하였다.

A mini-projector prototype employing a LED light source, a nontelecentric structure, and an LCOS panel for application in the integrated 3D display was fabricated. A seamless image was obtained by tilting an array of mini-projectors. Seamless quality was created by the excellent uniformity of the projection intensity on the mini-projector's screen, which was simulated as 98.34%. Great uniformity can be realized by optimizing the design of the light source and the optics configuration, which is the key to such realization.
