Business organizations today enjoy unprecedented connectivity over the Internet that directly affects their bottom line and their top line. Connectivity increases productivity and reduces cost of operations. It eliminates barriers resulting from distance and integrates the world. Nevertheless, businesses today face a challenging trade-off between securing their corporate assets and leveraging this ubiquitous connectivity to improve their operations. (omitted)

Cosmological linear perturbation theory has fundamental importance in securing the current cosmological paradigm by connecting theories with observations. Here we present an explanation of the method used in relativistic cosmological perturbation theory and show the derivation of basic perturbation equations.

This study is concerned with the applicable countermeasures for securing safety of ship from piracy attacks. For improvements and countermeasures, we analyzed the recent anti-piracy trends. In spite of international community's various activities for safety navigating, the number of piracy in Gulf of Aden and in the vicinity of Somali waters has been increasing dramatically in the last few years, so has the number of piracy on Korean vessels. In case of piracy attack which based on Somalia, it continues constantly and widely not only near shore, but coastal and oceanic waters. This study figures out the limitations of international community's efforts including military and legal improvements. There are no studies concerning the countermeasures of bridge protection by piracy. This study suggested the additional installation of outside door of bridge as well as the adjustment of piracy operation area(POA) of Korea navy.

According to railway safety regulations for securing the railway vehicle's quality and performance, it can be partly exempted that the performance tests and production inspections on the railway vehicles which are produced and assembled for the purpose of test and research. The reasons of this exemption are for ensuring maximum autonomy and for saving time considered the development period of railway vehicle. However, it was continuously demanded the necessity of supplementation on the confirmation about railway vehicle's quality & performance. Therefore, we added "The monitoring step" which is for securing the quality and performance in high speed railway vehicle's subsystem & compartment to supplement those tests & inspections in development. In this paper, based on a standard ABS(Activity Breakdown Structure) of railway vehicle and a WBS(Work Breakdown Structure) of the railway vehicle system, we investigate the necessity of monitoring in the High speed railway vehicle development. And by comparing and analyzing the essential requirements of international standard, IRIS(International Railway Industry Standard) & TSI(Technical Specification for Interoperability), we try to examine a standard monitoring procedure.

Today, due to the global recession car sales have been decreased rapidly and auto makers are competing continuously to expand their market share. Automakers are struggling in order to secure competitive cost and quality through continuous cost reduction and quality innovation activities to win in the competition. In this situation, auto parts makers are trying to reinforce price competitiveness by reducing COPQ (Cost Of Poor Quality) in the mass production stages by securing the quality of components in advance from the design stage through DFSS (Design For Six Sigma) activities which is 6 sigma approach in the R&D field. However, auto parts makers have been undergone various confusion, feeling difficulties to get interrelationship among various activities. Thus, this study is going to suggest approach method for much more effective R&D activities by securing interrelationship between ISO/TS 16949 system established in the auto parts industry and DFSS activities.
