국내의 장대터널 및 도심지내 터널시공과 시공계획이 증가함에 따라 터널굴착기술의 개발이 요구되고 있다. 국내의 터널 굴착방법으로 drilling & blasitng method가 주로 쓰이고 있는 실정이나 이 공법은 극심한 발파진동으로 현장주민의 민원과 인근 암반구조물에 피해를 입히는 단점이있다. 따라서 문제발생예측 지역에는 무발파 굴착공법인 TBM터널링을 사용하는 것이 효율적이다. 하지만 TBM 터널링은 drilling & blasitng method와 비교하였을 때 비경제적이므로 현장에서 꺼리는 실정이다. 이러한 한계를 극복하기 위하여 다양한 TBM 장비 및 시공기술이 요구된다. 또한 관련된 기술의 기준이 될 수 있는 시방서 및 설계기준의 지속적인 개정도 필요한 상황이다. 본 연구에서는 2015년 고시된 터널표준시방서내 TBM에 대한 개정 내용 및 관련 해설에 대한 내용을 다루고 있다.

In order to improve the existing S-57 standard, International Hydrographic Organization(IHO) has developed S-100 standard, a Universal Hydrographic Data Model(UHDM) expanded from ISO 19100 series standard to hydrographic area, and is in the process of its implementation. International Maritime Organization(IMO) has established CMDS based on e-Navigation strategy data standard as International Association of Lighthouse Authorities(IALA) established IHDM based on aids to navigation data standard and each data standard is linked with the S-100 standard. Fundamental concept and core principles of S-100 standard is suitable not only for the development of a wide range of hydrographic data and service production standard, including the next generation ENC, but also the development of product specification of non-hydrographic area. This study has examined the operation principle of S-100 standard and analyzed its implementation process as e-Navigation data in relation with ENC. It also noted the utilization of S-100 standard based e-Navigation and its potential effect via examining the development cases of S-100 standard-based product specification, such as nautical publication, ship reporting and pilot request, digital routing guide, tide and water level transmission and other important data cases of e-Navigation field.

Building Information Modeling (BIM) has been adopted in variety domain of construction industry. In this circumstances, interest of BIM model quality has been increased. In many countries, automated building code checking system by Industry Foundation Classes (IFC) has been developed and studied to use web based building permission systems. IFC is international standard of BIM format. However, the data structure of IFC does not include all of objects and properties about national building codes. In this paper, we developed the information specification between IFC data structure and national building code to increase interoperability. First, we drew the criteria from literature review to analyze the building code. And then, we analyzed building code and sorted objects and properties for automated building code checking. After that we made mapping table between the sorted data and IFC specification. Using the mapping table, we developed pre-specification about building codes information that does not exist in IFC specification. And the defined information can be used to develop the BIM modeling guide and national building permission system. The pre-specification support increasing the interoperability between user and automated building code checking system. Increasing thee interoperability makes improvement accuracy and reliability about result of automated building code checking.

HLA(High Level Architecture)는 미 국방성에서 제안한 분산 시뮬레이션을 위한 실시간 분산 데이터 공유를 위한 객체, 시간, 인터페이스 규격을 말한다. 이 HLA는 (1) Rules, (2) Interface Specification, (3) Object Model Template 둥의 3가지 구성요소로 정의되며, 인터페이스 명세를 구현한 것이 RTI(Run-Time Infrastructure)이다. RTI는 분산 운영체계가 응용 프로그램에게 서비스를 제공하는 것과 유사한 방법으로 Federation을 구성하고 있는 Federate들에게 상호연동에 필요한 서비스를 제공한다. 모든 서비스들이 표준에 적합하게 구현되었는지 테스트하기 위한 방법은 DMSO에서 제안한 RTI를 검증하기 위한 2단계 과정을 통해 테스트된다. 본 논문에서는 1단계 테스트를 위한 테스트 절차와 그 방법에 대해 논한다 테스트 결과를 토대로 각 영역에서 DMSO에서 제안한 Level One Test Procedures에 따라 RTI가 Interface Specification에 적합하게 구현되었는지 확인하며, 각 단계마다 올바른 명령과 예상된 결과가 나오는지 테스트하기 위한 Test Suite를 개발한다.

Light rail vehicle is optimized vehicle system for complex urban circumstance. LRT systems have many merits such as improve accuracy, speediness and safety. There are many LRT systems such as monorail, tram, automated guideway transit, linear induction motor propulsion and so on. These systems have operated in Japan and other advanced countries. In Korea, local government has many projects to apply the advanced LRT system. But there are no standardized specification, performance test specification, construction specification for monorail system, linear induction motor propulsion system, tram in Korea up to now. So, we need to establish of standardized to economical construction and safety. The linear induction motor system has been usually applied in Japan subway and ART(Advanced Rapid Transit) of Canada. In Korea, the linear induction motor system has been adopted for Yongin LRT and currently under construction. This paper covers the contents and technical base for main items of rolling stock, performance standard, carbody structure, bogie, electronic unit and brake equipment in order to implement linear induction motor LRT system according to local conditions.
