Nowadays, a lot of enterprise completed the ERP implementation and these ERP-based enterprises consider the construction of WMS or already have done it. However the enterprises which Implemented WMS linked with ERP have many problems In the warehouse management and the reason ran be summarized In two poults First. In the integration point of view, only Interface issue between ERP and WMS was taken into account, therefore it was hard to reflect the phased process change. Second, a large number of WMS functions were tried to implement at the same tune and these attempts caused confusion and Instability which Is Interpreted as a main reason of the WMS failure. This paper presents the phased construction method for the successful implementation or WMS and in the integration point or view, the phased process change appears naturally

The company protects the information of legacy system to satisfy all member in company. Integrating between applications is increasing recently because of e-Business activation. The e-Business activation also make between extra companies and intra companies integrated. This paper suggest on implementing the ERP using Phased Approach Method and the EAI(Enterprise Application Integration) with legacy system. This paper also suggest the standard method which would be used in implementing the EAI in another company and reduce the mistake during the EAI project. Therefore, it would be the one system between complicated systems through application integration, it would be also make shop floors visualized. This research would help users and service suppliers getting more advantages of e-Business system.

As the amount of informatization investment is rapidly increasing in many organizations, it becomes more inevitable to manage computing resources (information systems, computing facilities and manpower etc.) effectively. Specially, in public sector It is thought to be very important to achieve the economy of scale by integrating computing resources which are managed individually in many agencies. Also, our government have been recently making much efforts to raise the effectiveness of operating the information systems by promoting joint information use among many public agencies, enhancing the operating systems and the expertise of IS staff and applying the optimal information security systems. This study focuses on presenting the framework to effectively integrate omputing resources and proposing the ways of constructing and operating the integrated computing environment for the institutions and the affiliated groups under the Ministry of Culture & Tourism which are in charge of implementing cultural informatization. The main implications of this study are 1) building the ideal model of the integrated computing environment architecture suitable to cultural informatization area, 2) showing the criteria of deciding whether the organizations use the Integrated computing environment or not and how extensively they commit their computing resources to it, and 3) suggesting the ways of the phased integration and the change management to minimize confusion in the process of adopting the integrated computing environment and behavioral problems such as conflict and resistance of IS-related Personnel Influenced by Implementing the integrated computing environment.

The use of the Web-based Simulation Environment (WBSE) provides a strong influence on supply chain simulations. A virtual supply chain simulation is available to evaluate strategies for reducing response time to customers and for shrinking the finished goods inventory along its supply chain. This paper presents the basic concepts and definitions of Web-Based Global Supply Chain Management (WBGSCM) simulation system. It also discusses the advantages of supply chain simulation modules integration. A Time Synchronization Mechanism (TSM) called Phased Bucket Scheme (PBS) is introduced as an approach of the distributed simulation modules integration.

The main purpose of this study is to analyse what are the key financial innovations in the euro area electronic payment systems. TARGET2 is the RTGS-system provided through the Eurosystem. It is used for settling central bank operations, for large interbank transfers in euro and also for other euro-denominated transfers. The specific features of TARGET2 include processing in real time, settlement in central bank money and immediate finality. In addition, the SEPA is a payment-integration initiative of the European Union for simplification of bank transfers denominated in euro. In particular, the main innovations consist of the completion of the phased migration to the TARGET2 infrastructure, and the introduction of a single retail payment market in euro - the SEPA and its products, schemes and frameworks. As the study analyse, the key innovations consist of the TARGET2 introduction, SEPA establishment and migration towards the T2S system. These innovations will lead to a better understanding of the payment and settlement systems' behavior in stress situations and to enhance the stability of the euro area financial system. Moreover, the successful integration of the European payment and settlement infrastructures will further contribute to the integration of the European financial markets, as well as to their higher competitiveness.

In this paper, the plano-convex lens antenna fed by a single patch is studied for a microwave remote-traffic monitoring sensor with constraints of small size and low cost. Measurement of an AUT (Antenna Under Test) involves the considerations of a triangular groove for matched layer and metallic shielding effects. A formulation for extracting the parameters of a piano-convex lens antenna, based on geometrical optics, is introduced using Fermat`s principle of the equi-phased ray condition. Teflon ($\varepsilon_{{\gamma}}$/ =2.0) is chosen as a material of a plano-convex lens antenna for adjustment of aberrations on the lens surfaces automatically. A fabricated plano-convex lens shows 3-dB beamwidth of 7.5 degree and side-lobe level of -29 dB with an aperture distribution of the parabolic-squared taper on pedestal. This lens supports easier integration with the planar microwave circuits by using a microstrip single patch as a primary feeder of the lens antenna.feeder of the lens antenna.

The objective of this research project is empirically investigating factors influencing EPP system implementation based on the degree of volatility of business environment. The results show that computes with low volatility have successfully implement ERP system compared to companies with high volatility. This research project also identified success factors of each phased chartering phase, executive participation sound assessment of business condition, good understanding of ERP system and carefully constructed case are identified as success factors. During project expenditures, participation of various groups, technical resources, prefect and change management are found to be important for successful construction. Trained users, integration of systems, well-designed process and technical and human resource are found to be success factors during shakedown phase. Managers commitment technical infrastructure, system flexibility, and adequate resource for maintenance and renewing system are identified as success factors of onward and upward phase.

In this paper, the oscillator type active antenna used as an element of active phased array antenna is designed and fabricated using slot coupling. The radiating element and active circuit are fabricated on each layer respectively and coupled electromagnetically through slot on the ground plane. This structure can solve the problems such as narrow bandwidth of microstrip antenna, spurious radiation by active circuits, and spaces for integration of the feeding circuits which are caused by integrating antennas with oscillator circuits in the same layer. The active antenna in this paper, the oscillation frequency can be tuned linearly by controlling the drain bias voltage of FET. The frequency tuning range is between 12.37 GHz to 12.65 GHz when bias voltage is varied from 3V to 9V, thus frequency tuning bandwidth is 280 MHz (2.24%). The output power of antenna is uniform within 5dB over frequency tuning range. Therefore this active antenna can be used as an element of linear or planar active phased array antennas.
