서비스 지향 아키텍처는 하나의 실체가 다른 하나의 실체를 대신해 단위 작업을 수행하도록 하는 방식으로 두 개의 컴퓨팅 실체가 상호작용 하는 방법을 정의한다. 이 단위 작업은 "서비스"라고 지칭되며, 이 서비스 상호작용들은 독립적이고 느슨한 결합을 가져야 한다. SOA의 이러한 특징인 느슨한 결합과, 높은 상호운영성의 효과는 서로 다른 이용자들이 서로 다른 방식으로 서비스와 의사소통을 하기 위해 얼마나 유연한 메시지 통신이 가능한가에 따라 결정된다. 본 논문에서는 .NET Framework를 이용한 WCF 기반의 메시징 프레임워크와 통합된 데이터 표현 방식을 이용하여 서비스 지향 아키텍처를 기반으로 한 웹 서비스 애플리케이션과 일반적인 웹 서비스에 대해 애플리케이션의 응답 성능 및 시스템의 안정성과 성능 지수를 비교 분석하였으며 그 결과를 통하여 WCF를 이용한 SOA환경의 웹 서비스가 가지는 장점을 확인하였다.

최근 들어 비즈니스 환경의 변화로 인하여 비즈니스 프로세스 관리(BPM)라고 하는 경영관리기법이 주목을 받게 되었다. 그러나 다양한 업무환경에 따른 적합한 BPM을 도입하는 것에 대한 적절한 지침이 제시되어 있지 않다. 본 연구는 BPM에 요구되는 기능적인 사항과 기술적인 사항들을 분류하고 정의하여 기능적 및 기술적 체계를 제시한다. 또한 이러한 체계를 기반으로 BPM 평가방안을 제시한다. 제시된 평가방안은 4가지 BPM의 유형별로 다른 중요도를 반영하여 BPM을 평가할 수 있도록 하였다. 본 연구는 BPM을 도입하고자 하는 기업의 주요한 지침으로 활용될 수 있을 것이다.

The purpose of this study was pertinent design of the framework of the fixed bone anchored bridge using implants in the edentulous mandible through analysis of stress distribution by the three dimensional finite element analysis method. The results were as follows: 1. The L-shaped framework was favorable in restoring the edentulous mandible by implants and fixed bone anchored bridge. 2. The structure of the framework should be designed to endure the occlusal load because of stress concentration at the most distal abutment of the framework. 3. The stress at the distal implant where cantilever starts was twice as much as that of other portions. 4. Compressive stress was generated on the framework of the mesial side of the distal implant and extrusive force was induced to the mesially positioned implants. 5. The height of vertical plate was high as possible as can be to distribute stresses concentrating bucco-lingually and labio-lingually in the framework between abutments, 6. Reinforcement of the horizontal plate thickness was needed because stress was loaded more on the horizontal plate than on the vertical plate of the framework. 7. Lengthening of the vertical plate can compensate for any limitations in horizontal plate width.

객체지향 프레임워크는 개조, 합성이 용이한 클래스들로 분해될 수 있는 유연한 아키텍쳐를 제공함으로써 컴포넌트 기반의 효율적인 소프트웨어 개발을 지원한다. 프레임워크는 다수의 응용 소프트웨어의 개발에 반복적으로 재사용되므로 철저한 시험이 요구될 뿐만 아니라 재사용 시 확장된 프레임워크에 대해서도 추가적인 시험이 필요하다. 이를 위해서는 테스트 대상이 실행 가능한 형태로 제공되어야 하는데 그 구성 가능한 형태가 극히 다양할 뿐만 아니라 재사용될 때의 모든 형태를 예측하여 테스트하는 것은 현실적으로 불가능하므로, 재사용될 때마다 재구성되는 객체들의 구성 가능한 형태들을 동일한 특성을 갖는 유한 개의 그룹들로 분류하고, 각 그룹에서 시험 대상 실행 환경을 선정하여 시험하면 효과적인 시험이 가능하다. 본 논문에서는 재사용 시 다양한 형태의 객체 구조들로 개조, 확장될 수 있는 프레임워크의 가변부위 에 대해 객체 구성의 동일한 특성을 갖는 구조적 테스트 패턴들을 조직적으로 추출하는 방법과 각 패턴들로부터 시험 대상 객체 클러스터 즉, 테스트 대상 인스턴스를 선정하는 방법을 제안한다. 이 방법은 불필요한 테스트 케이스의 선정을 피하고, 테스트 대상 실행 환경의 체계적인 구축을 위해 사용될 수 있다.

The searching of an extensive document database for documents that are locally similar to a given query document, and the subsequent detection of similar regions between such documents, is considered as an essential task in the fields of information retrieval and data management. In this paper, we present a framework for such a task. The proposed framework employs the method of short-read mapping, which is used in bioinformatics to reveal similarities between genomic sequences. In this paper, documents are considered biological objects; consequently, edit operations between locally similar documents are viewed as an evolutionary process. Accordingly, we are able to apply the method of evolution tracing in the detection of similar regions between documents. In addition, we propose heuristic methods to address issues associated with the different stages of the proposed framework, for example, a frequency-based fragment ordering method and a locality-aware interval aggregation method. Extensive experiments covering various scenarios related to the search of an extensive document database for documents that are locally similar to a given query document are considered, and the results indicate that the proposed framework outperforms existing methods.

The seismic safety of the shear wall structure can be assessed through seismic fragility analysis, which requires high computational costs in estimating seismic demands. Accordingly, machine learning methods have been applied to such fragility analyses in recent years to reduce the numerical analysis cost, but it still remains a challenging task. Therefore, this study uses the ensemble machine learning method to present an improved framework for developing a more accurate seismic demand model than the existing ones. To this end, a rank-based selection method that enables determining an excellent model among several single machine learning models is presented. In addition, an index that can evaluate the degree of overfitting/underfitting of each model for the selection of an excellent single model is suggested. Furthermore, based on the selected single machine learning model, we propose a method to derive a more accurate ensemble model based on the bagging method. As a result, the seismic demand model for which the proposed framework is applied shows about 3-17% better prediction performance than the existing single machine learning models. Finally, the seismic fragility obtained from the proposed framework shows better accuracy than the existing fragility methods.

In order to overcome the key shortcoming of Hamilton's principle, recently, the extended framework of Hamilton's principle was developed. To investigate its potential in further applications especially for material non-linearity problems, the focus is initially on a classical single-degree-of-freedom elasto-viscoplastic model. More specifically, the extended framework is applied to the single-degree-of-freedom elasto-viscoplastic model, and a corresponding weak form is numerically implemented through a temporal finite element approach. The method provides a non-iterative algorithm along with unconditional stability with respect to the time step, while yielding whole information to investigate the further dynamics of the considered system.

T-splines are recently proposed mathematical tools for geometric modeling, which are generalizations of B-splines. Local refinement can be performed effectively using T-splines while it is not the case when B-splines or NURBS are used. Using T-splines, patches with unmatched boundaries can be combined easily without special techniques. In the present study, an analysis framework using T-splines is proposed. In this framework, T-splines are used both for description of geometries and for approximation of solution spaces. This analysis framework can be a basis of a CAD/CAE integrated approach. In this approach, CAD models are directly imported as the analysis models without additional finite element modeling. Some numerical examples are presented to illustrate the effectiveness of the current analysis framework.
