Network intrusion detection is becoming an increasing necessity for both organizations and individuals alike. Detecting intrusions is one of the major components that aims to prevent information compromise. Automated systems have been put to use due to the voluminous nature of the domain. The major challenge for automated models is the noise and data imbalance components contained in the network transactions. This work proposes an ensemble model, Attribute Subset Selector Bagging (ASUB) that can be used to effectively handle noise and data imbalance. The proposed model performs attribute subset based bag creation, leading to reduction of the influence of the noise factor. The constructed bagging model is heterogeneous in nature, hence leading to effective imbalance handling. Experiments were conducted on the standard intrusion detection datasets KDD CUP 99, Koyoto 2006 and NSL KDD. Results show effective performances, showing the high performance of the model.

Engineering changes are indispensable engineering and management activities for manufactures to develop competitive products and to maintain consistency of its product data. Analysis of engineering changes provides a core functionality to support decision makings for engineering change management. This study aims to develop a method for analysis of engineering changes based on On-Line Analytical Processing (OLAP), a proven database analysis technology that has been applied to various business areas. This approach automates data processing for engineering change analysis from product databases that follow an international standard for product data management (PDM), and enables analysts to analyze various aspects of engineering changes with its OLAP operations. The study consists of modeling a standard PDM database and a multidimensional data model for engineering change analysis, implementing the standard and multidimensional models with PDM and data cube systems and applying the implemented data cube to core functions of engineering change management, the evaluation and propagation of engineering changes.

China and South Korea have effectively reached a free trade agreement. The deal now faces legal and parliament reviews in the two countries. We need to discuss the recommendations on XML conversion with UN / CEFACT electronic documents. To solve this problem of interworking between these standards, Two kinds of translation rules is proposed for exchanging to UN / CEFACT Tag smoothly. For development and distribution of electronic documents to be conformed to international standards, it is enough to have the role of international activities continue to supply part of the domestic industry and the trends in participation and international standard. Our principal focus is on facilitating national and international transactions, through the simplification and harmonization of processes, procedures and information flows, and so contributing to the growth of global commerce. The agreement with South Korea will be China's ninth bilateral FTA.

ㆍ STEP is an International Standard (ISO 10303) - that defines the methodology to create computer interpretable product data models. ㆍ STEP Implementation - allows exchange and sharing of product data while retaining semantics throughout the product life cycle. ' STEP is in deployment - PDM data exchange at Boeing and others - Geometry data exchange at GM and others ㆍ The STEP community overcomes obstacles - “They will never finish the standard” (done 1994) - “They will never be able to transfer solids” (done 1995) - “They will never make solids transfer reliable” (done 1997) - “They will never implement all those Application Protocols”(TBD)(omitted)

An international standard for the product model data, STEP, and a standard for the distributed object technology. CORBA, will play a very important role in the future manufacturing environment. These two technologies provide background for the sharing of product data and the integration of applications on the network. This paper describes a prototype CAD/CAE enviroment that is integrated on the network by STEP and CORBA. Several application servers and client software were developed to verify the proposed concept.

A single window platform must be successfully established by implementing CDM/UCR in WCO and UNeDocs in UN/CEFACT, which is part of the framework of standards for secure and facilitate global trade. Core success factors in single window platform for international trade depend on political innovative capacity, advanced leadership of high ranking officials and departments in charge, effective collaborations between the ministries and offices concerned which are supported by supreme executives, self-controlled coordinations between users, convenience and access availability to users, promotion and marketing, identification on predictive impediments, financial raising and revenue model payable, communication's strategy, valid legal basis etc. To settle a stable ubiquitous e-trade platform, firstly, procedures and practices of customs clearance which different from one another mutually must be standardized globally. Secondly, the international standard electronic data exchanges must be introduced to facilitate and simplify customs clearing procedures by holding administrative informations in common between public institutions. thirdly, cooperative work model must be accepted with enhancing outsourcing business between reference groups (export-import firms and IT service providers).

Manufacturing Message Specification(MMS) was sewed as an International Standard by International Standardization Organization(ISO). MMS is being accepted throughout the world as a solution to communications among multi vendor factory floor environments. This paper describes an implementation of MMS which operates on Application Layer of Open Systems Interconnection(OSI) 7 layer model. MMS was implemented on MSDOS in apersonal computer environment.

These days international trade has been converting to e-Trade formation. At this point, Korea has been striving for the trade facilitation; reducing logistics cost and improving foreign competitiveness by computerization operations of the maritime transportation that logistics and customs clearance are involved. However, due to the substantial characteristic of logistics service, the necessity of flexible and various logistics service development using internet has been strongly suggested. In particular, the logistics service which could share documents related to international physical movement between shippers and logistics organization. In this regard, this study carried out interview to explore the problems of physical distribution service and to suggest development direction of e-logistics service. The reason why this survey carried out is that most of users want more effective e-logistic service that could diminish successively real expense decrease. After analysis of survey results, this paper presents the basic development direction and emphasis development subjects. Therefore, the basic direction is presented from four viewpoints; customer-oriented approach, service-oriented approach, total approach and step-by-step implementation. Furthermore six development subjects; web-based standard module development for small and medium forwarders, development of standard logistics ERP system, collaboration model between KTNET and KLNET, system improvement for real users, on-demand system building for SMEs and connection with legacy system have been required.

본 연구는 FRBR과 국제표준번호들의 특성을 분석한 후 저작, 표현형, 구현형, 개별자료의 4개 개체로 구조화되어 있는 FRBR의 저작개념을 토대로 국제표준번호들의 식별대상을 비교 분석하였으며, 분석결과를 요약하면 아래와 같다. 첫째 ISBN, ISSN, ISMN은 물리적 존재가 전제되어 있는 구현형을 대상으로 식별하고 있으며, IARN ISRC ISAN은 물리적 매체 대신에 기록내용을 전제로 하고 있는 표현형을 대상으로 식별하고 있다. 그리고 ISWC와 ISTC는 어떤 형식이나 수단으로 표현하기 이전의 작품을 전재로 하고 있는 저작을 대상으로 식별하고 있다. 둘째, FRBR의 포괄적인 '저작' 개념에 가장 부합하고 있는 것은 ISWC와 ISTC라고 할 수 있지만, 이들의 구체적인 저작개념의 규정을 분석해 보면 국제표준번호들의 저작개념이 기본적으로 작품의 창작성을 식별하기 위한 기능을 수행하는 반면, FRBR은 의미내용에 중점을 두고 있는 것과 같은 미묘한 차이점이 있다.
