본 논문은 기업 온톨로지를 기반으로 하는 비즈니스 프로세스 컨설턴트 시스템(BUPCO)의 설계를 기술한다. BUPCO 시스템은 사용자 인터페이스, 프로세스 표현 도구, 프로세스 평가 도구, 프로세스 분석 도구, 워크플로우 영향분석 도구, 프로세스 시각화 도구로 구성된다. 그 기반에 기업의 프로세스 지식을 표현하기 위해 기업 온톨로지를 구축하고 온톨로지 추론을 위한 프롤로그 추론기를 개발하였다. BUPCO 시스템은 기업 업무 환경의 변화에 빠르게 적응할 수 있는 최적의 프로세스 개선안을 제공하는 것을 목적으로 한다. 이 시스템을 통해 기업은 내부의 각종 비효율성을 제거하고 프로세스와 자원을 최적화함으로써 기업의 경쟁력을 제고시킬 수 있을 것이다.

The objective of the field professional education is to train up students with knowledge and technic and to supply them to companies. One of the good methods for the field professional education is to establish the school based enterprise(SBE) in school and university. The SBE program for the field professional education could improve the cooperation between industry and school(or university). In this paper, the foreign SBE programs and the domestic SBE programs are investigated and some improvement are suggested for the technical high schools.

Web Services offer many benefits over other types of middleware in distributed computing. However, usage of Web Services results in large network bandwidth since Web Services use XML-based protocol which is heavier than binary protocols. Even though there have been many researches to minimize the network traffic and bandwidth usages of Web Services messages, none of them are solving problem clearly yet. In this paper, we propose a transparent proxy with cache to avoid transfer of repeated SOAP data, sent by Web Service to an application. To maintain the cache consistency, we introduce publish/subscribe paradigm using WS-Eventing between the proxy and Web Service. The implemented system based on our proposed architecture will not compromise the standards of Web Service. The evaluation of our system shows that caching SOAP messages not only reduces the network traffic but also decreases the request delays.

The ROK military has established the MND-AF (Ministry of National Defense- Architecture Framework) and is applying it when developing architecture for Enterprise (MND), Segment (component) and Solution (weapons and force support system). The AMM (Architecture Meta model) of the MND-AF supports the establishment of interoperability by systematizing the architecture information structure defined by the Architecture artifact, describing the relationship between data and also by liking reference models and Information technology standard, common components, and MND-Meta data. which are interoperability standards. However, the MND-AMM has insufficient linkage with the standards, which places constraints on applying interoperability standards when developing Solution architecture. This study suggests a logical data model (OV-7c) from the MND-Meta-data-based Architecture meta model that will enhance the application of MND meta data managed by the MND interoperability standard when developing Solution architecture.

This paper investigates the importance and satisfaction levels according to factors on commercial Enterprise Resource Planning(ERP) packages in the view of end users when the ERP system is employed especially in SMEs. Considering the characteristics and functions of ERP packages, five factors (vendor, technology, function, A/S, price) are obtained based on the literature review. The proposed procedure consists of finding importance factors and satisfaction levels which support the selection of ERP packages for a certain SME. When a company tries to implement the ERP system, the findings in this paper suggest which ERP package is suitable for its own business environment.

In this paper, a building disaster notification system with MEC (Mobile Edge Computing) technology is proposed, which informs people in a building about the disaster. The overview of MEC is presented, and the structure and characteristics of network using MEC are described. In addition, the characteristics of a enterprise integration pattern based Apache Camel is described, and how to implement MEC with Apache Camel is presented. Finally, an implementation method of building disaster notification system with Apache Camel based MEC is proposed to quickly recognize disasters through sensors and to rapidly evacuate people from buildings.

This study is based on providing core infrastructure to make or extend an ERP strategy to make the proper model to cope effectively with various customer requirements and market changes through ERP improvement. The purpose of this study is to support making a competitive advantage by raising productivity and reducing costs as a result of making and applying the "mobile real time connection to ERP"model which is accessible anywhere and anytime using PDA and wireless LAN on the basis of mobile business concept. The model is implemented as the "mobile Material Management System" on the area of material management of ERP in the enterprise which already implemented ERP system. This model is also applied into other divisions of the enterprise. This case study shows that the proper application of ERP reduces costs by reducing business process lead time, increase productivity and customer satisfaction through mobility and instant connectivity and easiness of the system. It is recommended to apply this model into the ERP system which is used in most enterprise, to make a competitive advantage. To sum up, the model in this study can be applied into the enterprise which wants to reduce costs, increase productivity and customer satisfaction through ERP improvement.

The robotics industry, that is the major industry of the future and one of the new growth power, is actively studied around ETRI, that is the leading under state-run research institute of the advanced technique of U.S. and Japanese and knowledge economy part. And positive and negative and academic circles, the research institute, and the industrial circles communally pursue the intelligent service robot enterprise of a network-based called URC. This network-based intelligent robot does the RUPI2.0 platform and URC environment by the base. Therefore, a stability need to be enhanced in the through this near future when the research for the preexistence vulnerability analysis and security request is needed than the commercialized network-based intelligent robot in order to implement the network-based intelligent robot. Thus, in this paper, we propose the efficient authentication Framework which is suitable for the URC environment.
