Lately, electronic commerce through the Internet has been rising in attention. An important element in such commerce is EDI. EDI is mainly used with VAN but its use is not common due to the high cost of EDI transfer. Thus, only large corporations with frequent use of EDI are able U benefit from it, To smaller companies that have small usage, EDI is becoming a burden. Considering this fact as well as current changes within the enterprise environment, it is apparent that a new generation of EDI is required. To resolve the problems of VAN EDI, the proposed Internal EDI was implemented. Internet EDI deals with the use of the widely spread Internet instead of VAN. By using Internet EDI, it is possible to reduce the high cost that came when using VAN. There would be no extra transfer cost since transmission will be done through the Internet. Also, electronic commerce that is mostly used today between an individual and a company may grow to become a true electronic commerce between companies.

The aim of this study is to utilize system trading for making investment decisions and use technical analysis and Dynamic Time Warping (DTW) to determine similar patterns in the frequency of stock data and ascertain the optimal timing for trade. The study will examine some of the most common patterns in the futures market and use DTW in terms of their frequency (10, 30, 60 minutes, and daily) to discover similar patterns. The recognized similar patterns were verified by executing trade simulation after applying specific strategies to the technical indicators. The most profitable strategies among the set of strategies applied to common patterns were again applied to the similar patterns and the results from DTW pattern recognition were examined. The outcome produced useful information on determining the optimal timing for trade by using DTW pattern recognition through system trading, and by applying distinct strategies depending on data frequency.

The necessity of Power Quality(PQ) Management grow bigger because the disturbance strength in power system is increasing, on the other hand, the tolerance of electrical components is reducing with widely use of the IT and digital equipments. The domestic management standards on power quality are enacted based on the IEC standards in recent. Since the IEC standards defines the measurement and evaluation point on PQ as PCC(Point of Common Coupling) which is normally the point of penetration between customer and power company, the PQ monitoring system(PQMS) should be made to measure and manage the PQ of custom effectively. In this paper, therefore, the economical construction plan on PQMS using the wireless communication channel in distribution automation system is suggested, and the usefulness of the PQMS are shown by analyzing the PQM data with IEC standards.

Synchronization Markup Language (SyncML) is a specification of a common data synchronization framework for synchronizing data on networked devices. SyncML is designed for use between mobile devices that are intermittently connected to a network and network services that are continuously available on the network. We have designed and developed a data synchronization system based on the SyncML protocol and evaluated the throughput of the system using the stochastic Petri nets package (SPNP) and analyzed the relationship between the arrival rate and the system resources. Using this model, we evaluate various performance measures in different situations, and we estimate the relationship between the arrival rate and the system resources. From the results, we can estimate the optimal amount of resources due to the arrival rate before deploying the developed system.

SOAP(Simple Object Access Protocol) that is a late protocol for exchange of information with Web Services that is useful for implementing common functions in especially a large size business area, is a protocol that is a lightweight, XML-based protocol over HTTP for exchange to information in decentralized, distributed environments. In this paper, we implement SOAP-based Web Services that can use with a slip database, for common slip processing functions in enterprise accounts in order to enhance the transparency of transactions by slip processing system. The result of this paper will contribute to increasing the productivity of enterprises through enhancing the standardization of slip data, reusability of functions, convenience of access, and efficiency of implementing applications.

CAS(conditional Access System) is required for contents access such that only paid subscribers can watch channels in broadcast systems. In this paper, we design the CI(Common-Interface) module and implement a Multicrypt one of DVB scenario for interoperability. we use PADS2005 CAD tool for design and integrate the developed CAS into a STB(Set-Top-Box) on PCB board.

Collaborative product commerce (CPC) supports a collaboration that a global enterprise and customer related to life cycle of product share product information and a collaboration process for the collaboration, and integrating applications. In this paper, we use common data schema in order to solve a interoperability problem about shared product information between enterprises. And we map to common data schema from each other different data format. Therefore we implement CPC Adaptor in order to integrate distributed product information.

Trade-off of sorority and speed always exists in the latest network environment. Recently, developed security processors is improved very performance, and sorority connection algorithms of a lot of part were embodied by hardware. This high speed security processor is essential ingredient in string network security solution equipment development that require very big band width. In this paper, we wish to describe about design and implementation of 10 Giga VPN equipments. In this system, embodied 10 Giga to use Cavium company's Nitrox-II processor, and supports two SP14-2 interface and PCI interface. All of the password algorithm that password algorithm that support is used in common use VPN equipment for compatibility with common use VPN equipment are supported and support SEED algorithm developed in domestic. Designed to support IPsec and SSL protocol, and supports all of In-Line structure that is profitable in high speed transaction and the Look-Aside structure that is profitable in practical use degree of NPU(Network Processor Unit).

To overcome the common deficiencies found in two-way slabs, such as excessive cracking around columns, excessive deflections and low punching shear strength, it was proposed to investigate the strategic use of steel fiber-reinforced concrete. Providing fiber-reinforced concrete results in an increase in the punching shear resistance, a significant increase in the ductility, greater post-cracking stiffness and better crack control.
