In this paper we describe interoperability maturity measurement, due to highlight a momentous issue on interoperability between heterogeneous distributed component based systems. it also suggests one of various ways for supporting interoperability between each other different component based systems, that is, using web services based mechanism and also revises 'LISI (Level of information systems interoperability)' model to measure interoperability maturity. We also develop the interoperability questionnaire based on the interoperability factors considered at each phase of component based development process, which is possible to measure interoperability maturity between heterogeneous distributed component systems. Based on revised interoperability maturity model and questionnaire we measure each interoperability maturity on examples of two different implementations, that is, web services and distributed object based mechanism. As a result, we suggest an enhanced interoperability way based on analysing problems af these measured results.

The purpose of the present study is to suggest the meta data of the attribute mapping for interoperability from IFC to CityGML. For this, we analyzed the interoperability issue including the neutral information model structure such as IFC, CityGML. To solve the interoperability problem between IFC and CityGML model which is the neutral GIS format, We proposed the meta data including the mapping rule. The meta data is consists of the connection information between BIM and GIS model, the mapping rule based on the perspective of the use-case, the operator and the attribute. By using this, XML to represent the meta data is defined and the information mapping system is developed.

The purpose of the present study is to suggest the extern BIM reference model for interoperability between BIM and GIS. After we surveyed the research progress and usecases related to the interoperability to do this, we analyzed the architecture of the neutral model such as IFC, CityGML to identify the differences between these and expand CityGML model. By using this result, we proposed the external BIM reference model including the metadata which defines mapping rules from IFC to CityGML.

Many of domestic disaster response agencies do not have adequate interoperability because they are not considering inter working for other agency's radio network and building their own disaster and safety radio network. It will urgently establish interoperability guidelines at pan-government level to solve this problem, but even it is not concrete discussion yet. In this paper, in order to develop for interoperability guidelines at pan-government level, we were defined the level of interoperability and were designed standard inter working model.

기존의 사용자 및 전사적인 조직의 시스템은 대부분 혼합 및 이질적인 컴퓨팅 시스템을 가지고 있다. 이러한 결과 시스템들 간에 원활하게 작동할 수 있도록 많은 이질적인 인프라의 구축 및 비용이 들어가고 있다. 이런 결과 상호운용성의 문제점이 중요하게 대두되었다. 본 논문에서는 협업 컴포넌트 상호운용성을 위한 J2ME 기반 아키텍처 모델을 제안하였다. 협업 컴포넌트 상호운용성을 위해서 다수의 벤더 환경에서 환경에 대한 기술을 구축할 아키텍처를 정의하였다. 이러한 아키텍처들은 크게 네트워크. 데이터, 애플리케이션, 관리로 이루어진다 이러한 결과 컴포넌트의 재사용성으로 인해 기존의 다양한 웽 애플리케이션 환경에서 활용이 가능하고 확장도 용이하게 하였다. 또한, 모바일 협업 플랫폼 인프라 구축 및 운영비를 절감할 수 있다.

Recently, as South Korea has joined the OSJD, the rules of the OSJD need to be applied to South Korea. Therefore, the railways are connected to the continent railway in terms of software, but the railway systems in neighboring countries have been developed and operated for a long time, and are quite different with some restrictions in terms of hardware. Therefore, this study analyzed the current railway systems of neighboring countries' based on the TSI used in Europe for technical interoperability. A real operation with the operation models within the specific route was assumed and vector functions for the Infrastructure vector & Rolling stock vector were produced. The IOP value was calculated by working out the interfacing matrix value between the infrastructure vector and rolling stock vector. As a result of calculating the IOP in a specific route, which is from Busan South Korea to Vladivostok with the diesel locomotive hauling freight cars, the value was only 22%, which is fairly low in terms of the interoperability. In other words, there are 77.8% restricting items preventing their interoperability. Such restricted causes should be improved to increase the technical interoperability in the long term. Moreover, and when railway systems are constructed and manufactured, it is important to keep IOP 100% to increase the operating efficiency in continental railways.

e-비즈니스에서 사용되는 정보교환 문서는 효율적으로 정보를 전송하고 시스템에 독립성을 갖고 있어 거래 파트너간 상호 운용성을 향상 시켜야 한다. 기존의 정보 교환 전자 문서는 e-비즈니스에서 사용함에 있어서 정보교환 및 상호 운용성 측면에서 문제점들이 발생하였다. XML의 등장으로 정보 교환 및 상호 운용성에서 발생되었던 문제점들을 해결할 수 있는 계기가 되었다. XML문서의 논리적인 구조를 표현하기 위해서는 문서 원형을 정의 할 수 있는 DTD문서가 필요하다. 각 e-비즈니스 XML 문서에 맞는 DTD 문서들이 존재하며 이러한 DTD 문서를 보다 쉽고 효율적으로 작성 할 수 있는 e-비즈니스 DTD문서 편집 시스템의 필요성이 증대되고 있다. 이에 본 논문에서는 e-비즈니스 XML 문서에서 사용되어지는 DTD문서를 보다 쉽고 효율적으로 편집 할 수 있는 DTD문서 편집 시스템의 설계 및 구현 하였다.

In this paper, we discuss the current status of ROK-US wargame model interoperability and propose the future federation architecture. ROK and US Armed Forces have made an effort to make their wargame model interoperable to fulfill operational requirements since 1999. Currently, they have achieved some degree of their final goals even though there is long way to go. ROK Armed Forces is now considering future federation architecture. We propose the future federation architecture of ROK-US wargame model interoperability considering technical advantages and system availability. It will be the next federation architecture led by ROK side for the ROK Armed Forces joint exercise and ROK-US combined exercise.
