우리나라는 보안산업 현장에 적용할 적합한 비즈모델 분석 방법론을 발견하기 어렵고 단편적 이론은 존재하지만 종합적 분석 방법론은 희소한 실정이다. 정보보안 기업 비즈모델 분석은 외부요인과 내부요인에 관해 수집된 정보를 통합하고 포괄적으로 분석하는 정보시스템 개발이 요구된다. 비즈모델 분석을 위한 정보시스템의 소프트웨어 아키텍처는 시스템 설계의 초기 결정사항으로서 초기 결정은 설계, 개발, 테스트, 유지보수에 지속적인 영향을 미친다. 정보보안 비즈모델 분석시 BMO에 기반한 소프트웨어 아키텍쳐는 정보시스템의 목적이나 사명 수행을 지원 한다. 정보보안 비즈모델 분석을 위한 정보시스템은 여러 이해관계자들이 사명과 환경을 결정하며 그 결과가 아키텍처 기술서로 문서화 되어야 활용될 수 있다. 아키텍처 기술서는 소프트웨어 아키텍처를 결정한 근거를 제시하기 때문이다.

Existing reinforced concrete frame buildings designed for vertical loads could only suffer severe damage during earthquakes. In recent years, many research activities were undertaken to develop a reliable and practical analysis procedure to identify the safety level of existing structures. The Incremental Dynamic Analysis (IDA) is considered to be one of the most accurate methods to estimate the seismic demand and capacity of structures. However, the executions of many nonlinear response history analyses (NL_RHA) are required to describe the entire range of structural response. The research discussed in this paper deals with the proposal of an efficient Incremental Modal Pushover Analysis (IMPA) to obtain capacity curves by replacing the nonlinear response history analysis of the IDA procedure with Modal Pushover Analysis (MPA). Firstly, In this work, the MPA is examined and extended to three-dimensional asymmetric structures and then it is incorporated into the proposed procedure (IMPA) to estimate the structure's seismic response and capacity for given seismic actions. This new procedure, which accounts for higher mode effects, does not require the execution of complex NL-RHA, but only a series of nonlinear static analysis. Finally, the extended MPA and IMPA were applied to an existing irregular framed building.

The appropriate design of a mooring system to maintain the position of an offshore structure in deep sea under various environmental loads is important. Fatigue design of the mooring line considering OPB/IPB(out-of-plane bending/in-plane bending) became an essential factor after the incident of premature fatigue failure of the mooring chain due to OPB/IPB in the Girassol region in West Africa. In this study, mooring line fatigue analysis was performed considering the OPB/IPB of a spread moored FPSO in deep sea. The tension of the mooring line was derived by hydrodynamic analysis using the de-coupled analysis method. The floater motion time histories were calculated under the assumption that the mooring line behaves in quasi-static manner. Additional time domain analysis was carried out by prescribing the obtained motions on top of the selected critical mooring line, which was determined based on spectral fatigue analysis. In addition, nonlinear finite element analysis was performed considering the material nonlinearities, and both the interlink stiffness and stress concentration factors were derived. The fatigue damage to the chain surface was estimated by combining both the hydrodynamic and stress analysis results.

In general, an Architecture of a system is embodied as applied results of a requirement analysis of a system in early development phase. These efforts play a important role in analyzing and understanding a system considering operational, functional, and physical view and deriving a correct solution before developing the system. In this paper, the architecture of the Tube Transportation System(TTS) known as the new transportation system in Railway Domain is depicted by performance parameter has already developed. The existing performance parameters are shown by a variety of types with many meanings rather than types of general requirements refined. As these early performance parameters have analyzed and complemented to a level of requirement by requirement managers and other domain specialists, the architecture of the Tube Transportation System was developed systematically and then system requirements will be drawn up definitely. The presented architecture will provide a framework of developing a TTS and also offer an information in performance analysis of TTS.

Intellectual capital is one of the most valuable assets of any enterprise. This empirical investigation examines the causal relationship between intellectual capital and the performance of architecture firms. More than 100 architecture firms across Taiwan have each been assessed for the levels of human capital, structural capital, relational capital, and business performance. The results suggest that the architecture firms exhibit higher levels of relational capital. However, the firms indicate relatively low levels of human capital. Additionally, the results from the correlation analysis suggest that all the four measures (human capital, structural capital, relational capital, and business performance) are highly correlated. The findings from the path analysis also indicate that human capital may influence the performance of architecture firms via structural capital and relational capital.

The recent completions of free-form spatial structures provide us a very attractive form. To realize such an extraordinary shape, it is absolutely necessary that the connector systems have to be investigated the characteristics of the systems and analyzed with a practicable method. In this context, this research consists of not only literature research but also numerical analysis with selected connector systems, which was adopted in real free-form spatial structures. For numerical analysis, especially, finite element analysis (FEA) is performed with a various test parameter using a commercial program ANSYS. Consequently, the general characteristics of node connectors the moment-rotation-curves are presented by considering a large deformation effect as well as a multi-linear material properties.

System integration is an important element for the construction of naval combat ships. In particular, because impeccable combat system integration together with the sensors and weapons can ensure the combat capability and survivability of the ship, the integrated performance of the combat system should be verified and validated whether or not it fulfills the requirements of the end user. In order to conduct systematic verification and validation, a data analysis tool is requisite. This paper suggests the Data Extraction, Recording and Analysis Tool (DERAT) for the data analysis of the integrated performance of the combat system, including the functional definition, architecture and effectiveness of the DERAT by presenting the test results.
