To transform the enterprise system into the 'Real Time Enterprise' with respect to IT, I suggest the conceptual application model which is composed of pieces(components) extracted from different packaged applications working in a heterogeneous environment based on the 'business activity' in other words, business services provided by internal (inter-enterprise) and external (extended enterprise) application to support a business activity within in an enterprise and the design mechanism focusing service tier which acts as intermediate tier within application architecture.

To improve the educational system of Korea Maritime Police Agency(KMPA), the authors investigate and evaluate the present course and curricula in details comparing with the systems of USCG and JCG. As a result, it is suggested that KMPA find the diverse route to recruit good-quality officers, develop the future-oriented system, coordinate the course and curricula to meet the role and mission of KMPA. Besides, KMPA build the own training facility and train special instructors.

Utilizing the simulation approaches, the dynamic production scheduling system FOLS(Flexible flowshop On-Line Simulation) is developed under the flexible flowshop environment. When an interruption such as machine failure/recovery is occurred at the shop floor, the FOLS system performs evaluations for job selection rule oriented alternatives, and generates a dynamic production schedule based on the collected current shop floor data. For the case study, the FOLS system is applied to the printed circuit card assembly(PCCA) line and simulation results are reported.

XML and CORBA have vast potential to improve software interoperability and to facilitate data exchange across applications and people from various disciplines and vendors. This Paper describes a framework for the integration and validity evaluation of injection mold design problems in a network-oriented design environment, based on In and CORBA. An overview of the framework is provided and an application to a design phase of injection mold is illustrated. The example illustrates how design validities are notified and design directions are provided to the designer during design process.

본 논문에서는 웹 기반의 분산 소프트웨어 개발 환경에서 원시 코드 중심의 버전뿐만 아니라 원시 코드 이전 단계의 UML 기반의 소프트웨어 개발 환경에서 발생하는 다양한 설계 객체들을 일정한 형태로 구축하여 효율적으로 관리하는 방법론을 제시하였다. 또한, 웹을 기반으로 한 분산 소프트웨어 개발 과정에서 발생하는 버전들을 일관성 있게 관리하기 위해 버전 규칙에 기초한 웹 기반의 중앙 버전 관리자를 설계하였다.

분산 객체 컴퓨팅은 인터넷의 활성화와 더불어 각광받고 있는 분야중의 하나이며 많은 응용 소프트웨어들이 분산객체 기술을 이용한 컴포넌트 형태로 개발되고 있다. 분산 객체 컴퓨팅 기술을 기반으로 한 CORBA는 새로운 세대의 분산 컴퓨팅 플랫폼이며, 보안은 항상 분산 컴퓨팅 플랫폼의 기본적인 문제이다. 따라서, CORBA 플랫폼에서의 보안 서비스의 적용은 매우 중요하다. 본 논문에서는 보안의 표준들과 분산 계산 플랫폼의 보안 모델들을 참조하여 CORBA 보안 서비스 규약에 따르는 객체지향 분산환경에서의 객체보안 서비스를 제시한다.

유비쿼터스 환경에서는 다양한 종류의 응용 서비스가 존재한다. 이러한 서비스를 지원하기 위한 기반 구조로 제안된 소프트웨어 시스템들은 다양한 정보를 수집하여 그 중 의미 있는 정보를 이용한다. 본 논문에서는 서비스의 특성을 반영하여 네트워크를 구성할 수 있는 방법을 제시한다. 특히, 서비스들이 필요로 하는 여러 가지 요구 사항을 반영하여 라우팅 메트릭을 만들고, 온톨로지에 저장해 두어 서비스들이 필요로 하는 특성을 잘 반영할 수 있다.

This paper presents a multitier GIS architecture to adapt to large-scale distributed networks and to improve data transfer performance with intelligent caching technique. We design this system using UML based on object-oriented analysis. We show some advantages in our proposed system against the ordinary GIS, in special, suitability to distributed networks.
