HLA(High Level Architecture)는 시뮬레이션의 재사용성 증진과 상호운용성 확보를 목표로 하는 국제기술표준이다. 전세계적으로 HLA 기반 페더레이트 간의 연동을 통한 페더레이션 구축이 다양한 분야에서 적용되고 있으며, 국내 군사 분야에서는 KR/UFG 한미 연합연습 등에서 활용되고 있다. 현재 미 국방성에서는 페더레이트의 HLA 준수여부를 사전에 확인하는 HLA 적합성 인증시험이 강조되고 있다. 그러나 미국의 인증시험은 인증도구의 제한사항으로 인해 페더레이션 저장/복구 서비스 등 일부 HLA/RTI 서비스들에 대한 기능검사는 불가능하며 페더레이트 간의 교환데이터에 대한 검사 또한 배제되어 있다. 본 논문은 이러한 문제를 해결하기 위해 국내 실정에 맞는 한국형 HLA 적합성 인증시험 체계를 제안한다. 이를 통해 효과적인 인증시험 수행이 가능하며 각 페더레이트들 간의 상호운용성을 향상시킬 수 있을 것으로 기대한다.

Personal Robot System in developing, have a module architecture, each module are connected through heterogeneors network systems like Ethernet, WLAN (802.11), IEEE1394 (Firewire), Bluetooth, USB, CAN, or RS-232C. In developing personal robot system we think that the key of robot performance is interoperability among modules. Each network protocol are well connected in the view of network system for the interoperability. So we make a bridging architecture that can routing, converting, transporting data packets with matcing each network's properties. Furthermore we suggest a advanced design scheme for realtime / non-realtime and control signal (short, requiring hard-realtime) / multimedia data (large, requiring soft-realtime). By some application systems, we could test performance, interoperability and stability. In this paper, we show our design concept, middleware architecture, and some applications systems using this middleware.

Recently, because of the extensive use of geographic information in the various fields, the requirement for the easy circulation and utilization of the various geographic information among the individuals, organizations, societies and countries is raised. In order to support the interoperability of the heterogeneous geographic information in the various fields, OGC(Open GIS Consortium) proposed the GML(Geography Markup Language) specification that defines the XML encoding rule about the heterogeneous geographic information. In addition, ISO/TC 211 adopted the GML specification to make it as the international standard. Therefore, in this paper, we first analyzed the GML 3.0 specification in detail that can support the interoperability of the heterogeneous geographic information. And then we suggested and applied the mapping rule that define the encoding method to improve the encoding process easily and efficiently. Finally, we designed and implemented the GML 3.0 encoding system using the mapping rule to encode the geographic information that was constructed in spatial databases into the GML 3.0 document. Especially, we used ZEUS as a spatial database system to test our encoding system in this paper.

국내 전자상거래의 표준으로 채택된 ebXML에 대한 관심이 집중되면서 국내외적으로 ebXML 솔루션들의 검증의뢰에 대한 대비책의 필요성이 대두되고 있다. 이 중 BPSS의 검증을 위한 시험도구는 국내외적으로 전무한 상태이다. 이에 ebXML에서 가장 중요하고 필요한 부분으로써 ebMS 표준적합성 및 상호운용성과 연계된 ebXML BPSS 검증 체계 확립이 절실히 요구된다. 본 논문에서는 ebXML BPSS 검증항목으로 작성된 케이스 항목에 따라서 문서의 적합성 여부를 평가하기 위한 시스템 모델을 제안하고자한다.

In this research, a new methodology to perform building energy analysis using Industry Foundation Classes (IFC) standard has been studied. With the help of Archicad 14 modeling software, a 3D test model is generated and then exported to IFCXML format. A ruby code program retrieves the building information from the resulting IFCXML file using Nokogiri library. An INP file is created and gets ready for next energy analysis step. DOE 2.2 program analyzes the INP file and gives a detailed report of the energy cost of the building. Case study shows when using the IFC standard method, the Interoperability of the energy analysis is greatly improved. The main stream 3D building modeling software supports IFC standard. DOE 2.2 is able to read the INP file generated by IFC file. This means almost any 3D model created by main stream modeling software can be analyze in terms of energy cost Thus, IFC based energy analysis method has a promising future. With the development and application of IFC standard, designers can do more complex and easy-to-run energy analysis in a more efficient way.

TTCN-3(Testing & Test Control Notation Version 3)은 2001년 ETSI에서 표준화한 국제 표준 테스트 언어이다. TTCN-3은 프로토콜 적합성 시험에 일반적으로 사용하고, 특정 부분의 모듈이나, CORBA 기반의 플랫폼 및 API 시험 등에 적용이 가능하다. 또한 적합성 시험뿐만 아니라 연동 시험, 반복 시험, 플랫폼 시험 등의 다양한 시험에 적용이 가능하다. IEC61850 은 SCADA(Supervisory Control And Data Acquisition) 시스템에서 SAS(Substation Automation System)를 위해 제안된 프로토콜이다. 본 논문에서는 TTCN-3 적합성 시험 언어를 이용하여 IEC 61850 상호 연동성 시험기를 Windows 환경에서 구현하였다. SUT(System Under Test)로는 리눅스 운영체제 기반의 IEC61850 Server Simulator를 사용하였다. 본 논문에서 시험한 적합성 시험 항목은 "IEC61850 - Part10" 문서의 테스트 항목들 중 "Server, Logical device, Logical node, and data model"의 Positive test case_Srv5 항목을 시험하였다.

The substation is a critical node in the power network where power is transformed in the power generation, transmission and distribution system. The IEC 61850 is a global standard which proposes efficient substation automation by defining interoperable communication and data modelling techniques. In order to achieve this level of interoperability and automation, the IEC 61850 (Part 6) defines System Configuration description Language (SCL). The SCL is an XML based file format for defining the abstract model of primary and secondary substation equipment, communications systems and also the relationship between them. It enables the interoperable exchange of data during substation engineering by standardizing the description of applications at different stages of the engineering process. To achieve the seamless interoperability, multi-vendor devices are required to adhere completely to the IEC 61850. This paper proposes an efficient algorithm required for verifying the interoperability of multi-vendor devices by checking the adherence of the SCL file to specifications of the standard. Our proposed SCL validation algorithm consists of schema validation and other functionalities including information model validation using UML data model, the Vendor Defined Extension model validation, the User Defined Rule validation and the IED Engineering Table (IET) consistency validation. It also integrates the standard UCAIUG (Utility Communication Architecture International Users Group) Procedure validation for quality assurance testing. Our proposed algorithm is not only flexible and efficient in terms of ensuring interoperable functionality of tested devices, it is also convenient for use by system integrators and test engineers.
