This case study covers the Knowledge Management research paper that explores the clear idea about the knowledge practicesthat are used in the corporate sector to achieve the strategic advantage over the competitors. The quoted example of the three manufacturing firms TATA MOTORS, BHEL, and M&M have tried to compare the Knowledge practices in these firms, which explores the concept clearer that the competitors can use the same or the different type of knowledge practices to achieve the competitor advantages. In order to help knowledge management goals, an integrated knowledge management system consisting of the knowledge management techniques and technologies are used. The knowledge Management is supported by different techniques and practices whichare knowledge content, people skills, technology and strategy based. The technology and techniques supports these factors of knowledge management. The paper discuss different techniques and processes adapted by three Indian organizations and a comparison is made to suggest the guidelines of KM practices to manufacturing Industries.

국내 500MW 석탄화력발전소에서 사용중인 역청탄 (앵글로탄)과 아역청탄 (타니토탄)을 입수하여 석탄회의 기본적인 연료 및 연소특성을 살펴보았다. 또한, 열기계분석기를 이용하여 석탄 회에 대한 고온 용융특성을 평가하고 최근 새롭게 제시된 BHEL 슬래깅 지수를 구하였다. 아역청탄인 타니토탄 회는 $1,200{\sim}1,250^{\circ}C$에서 대부분의 용융이 발생하고 있으나 역청탄인 앵글로탄 회는 상대적으로 높은 온도인 $1,550^{\circ}C$ 부근에서 급격한 용융이 발생하였다. 석탄 회의 용융특성과 석탄중의 회 함량을 고려한 BHEL 지수는 두 탄종 모두 슬래깅성이 높은 것으로 나타났다. 반면, 기존의 슬래깅 지수들은 서로 다른 슬래깅성을 보여주었다.

Torque tubes in High Temperature Superconducting (HTS) motor transfer torque from superconducting field winding rotor to the room temperature shaft. It should have minimum heat conduction property for minimizing the load on cryo-refrigerator. Generally, these torque tubes are made with stainless steel material because of high strength, very low outgassing and low thermal contraction properties at cryogenic temperatures and vacuum conditions. With recent developments in composite materials, these torque tubes could be made of composites such as Kevlar and S-Glass, which have the required properties like high strength and low thermal conductivity at cryogenic temperatures, but with a reduced weight. Development and testing of torque tubes made of these composites for HTS motor are taken up at Bharat Heavy Electricals Limited (BHEL), Hyderabad in collaboration with Central Institute of Plastics and Engineering Technology (CIPET), Chennai and Indian Institute of Technology (IIT), Kharagpur. As these materials are subjected to vacuum, it is important to measure their outgassing rates under vacuum conditions before manufacturing prototype torque tubes. The present study focusses on the outgassing characteristics of Kevlar and S-Glass, using an Outgassing Measurement System (OMS), developed at IIT Kharagpur. The OMS facility works under vacuum environment, in which the test samples are exposed to vacuum conditions over a sufficient period of time. The outgassing measurements for the composite samples were obtained using pressure-rise technique. These studies are useful to quantify the outgassing rate of composite materials under vacuum conditions and to suggest them for manufacturing composite torque tubes used in HTS motors.
