In every sectors of industry, the Business Process Reengineering(BPR) has been applied for taking competitive advantage under rapidly changing environment. A company adopting the BPR has begun to consider the introduction of Enterprise Resource Planning ERP systems. ERP systems can integrates many core activities of business, such as manufacturing management, human resource management, financial management, supply chain management by applying the best practices to facilitate a rapid decision-making, cost reductions, and organizational control. Unfortunately, however, many tentative risk factors are existed through each phase of the introduction of ERP systems. As a result, it can bring an enormous benefits to a company or it can be a disastrous for organization. Therefore, two critical questions regarding the introduction of ERP systems should be analyzed before actual introduction has happened. They are "how can ERP systems be introduced successfully\ulcorner" and "what are the critical success factors for each phase of introduction of ERP systems\ulcorner". Through this research, We studied and analyzed the characteristics of critical success factors requiring at each phase of the introduction of ERP systems by applying the questionnaire survey method. Finally, we suggest the list of barriers and critical success factors for each phase of introduction of ERP systems.tion of ERP systems.

The object of this study is to elicit major success factors along with the phases of implementing the BPR in case of public corporations. To obtain the goal of this research, (1) this study reviews and integrates the major previous BPR studies and shows critical success factors of implementing BPR projects coincided with the characteristics of the public organizations. (2) This study has analyzed and arranged the details of BPR projects of public corporations in South Korea through the literature survey, the questionnaire and the interview. (3) This study classifies 40 critical success factors which were identified in existing studies into ones belonging to 3 phases of BPR projects implementation: Introduction Phase, Execution Phase and Stabilization Phase. (4) This study has tested the relation between critical success factors on each stage of BPR projects implementation and the performance variables. It has proven that there is the statistically significant correlation between the success factors and the performance. The findings of this study are thought not only to be useful as a practical guideline in carrying out BPR project Implementation but also to provide significant basis for constructing the theoretical framework of effective BPR project implementation strategy.

1. INTRODUCTION : Since the knowledge of vitrification phenomena can lead to a better understanding of the mechanism of membrane formation, it is desirable to include vitrification line into the phase diagrams. While the final morphology obtained during phase inversion depends upon the kinetics as well as the thermodynamics of the phase separation, the equilibrium phase diagram and vitrification line for amorphous polymers are still a good tool for controlling the morphology and interpreting the membrane structure.

1. Introduction : The growth of membrane science was initiated by the invention of asymmetric membrane which can be formed by the technique known as phase inversion. The basic procedure of phase inversion involves casting a thin film of polymer solution onto a suitable substrate followed by immersion in a coagulation bath (quench step). Therefore, events occurring during the quench period, at which time solvent-nonsolvent exchange and eventual polymer precipitation take place, can play a controlling role in the determination of ultimate membrane structure.

During the administration of a construction project, various types of participants are engaged in the project. From the design phase to the maintenance phase, these participants may confront many risks. To avoid these risks, participants should utilize an insurance company or a bond company. The types of risks and liability that a construction manager may face are listed in the construction law or contract. But there are some arguments related to risk transferring and the content of risks. For this reason, construction managers must carefully consider any possible risks in the contract and the construction law. Therefore, for construction managers to deal with risks appropriately, the introduction of a legal requirement to carry professional liability insurance, a defined compensation range for damages, a method of guarantee in the event of defects, a defined compensation claim period for damage, and a method of damage claim were suggested in this study.

In this paper, the results of safety activities for Airport Railroad are introduced according to CENELEC standards. The procedures of safety activity were redefined as 6 phases such as Requirement Analysis phase, Design phase, Manufacture phase, Installation phase, Test & Commissioning phase and Operation phase to ensure the coincidence with 14 phases recommended in CENELEC standard. And the safety activities were implemented in the aspect of the overall E&M system level and in the aspect of each system level for 6 sub-systems consisting of that E&M system to ensure the safety for Airport Railroad using the general methodology such as FMECA.

Construction industry has been participated in the effort for the reduction of environmental pollution such as introduction of green building certification, enactment of environment related regulation. However these efforts are focused on the design and maintenance phases of entire life cycle, construction phase that can occur intensive environmental impact in a short period is insufficient. Therefore this study aim to derive environmental management factors in construction phase and assess them using reliability analysis and factor analysis. As a results, the 20 factors was classified into 4 superordinate such as 'plan and supervision', 'environmental factor management', 'licensing management', 'surrounding environment management'.Based on result of this study, further study should be developed the checklist for effective environmental management in construction phase.

A series of cinchona alkaloid-derived dimeric quaternary ammonium salts were prepared as chiral phase-transfer catalysts by the introduction of various functional groups on the phenyl ligand. Among them. the 2-F-substituted derivative 21 showed the highest enantioselectivity in the alkylation of the glycine anion equivalent 1 (97->99 ％ ee).
