본 논문은 독일통일 후 구동독지역에서 실시된 학제통합 과정에 대한 고찰을 통해 남북한 통일 후 교육통합 과정에서 고려해야 할 시사점을 도출하는데 연구의 목적이 있다. 독일 통일 전후 단계에서 구동독의 학제는 전환기 과정을 거쳐 구서독의 학제에 통합되었다. 구동독의 학제통합은 전환기 조치를 통한 안정적 관리, 동서독 간의 협의 추진, 지역별로 상이한 학제 체제의 도입, 통일 후 사회적 변화 상황에 대한 유연한 대처의 측면에서 긍정적인 특성을 가지고 있다. 반면, 단기간의 개편 추진, 구동독 학제 체제에 대한 고려 미비, 학제 통합 후 내적 인프라 구축의 어려움 등의 한계를 나타냈다. 통일독일의 학제통합 과정 사례는 남북한 통일 후 교육통합을 준비해야 하는 우리에게 학제통합의 안정적 추진을 위한 방안의 수립, 북한 학교체제에 대한 면밀한 검토, 학제통합에 따른 내적인프라 구축 방안 마련 등이 필요하다는 시사점을 제시한다.

Integration of finite element analysis (FEA) software into various software platforms is commonly used in coupling systems such as systems involving structural control, fluid-structure, wind-structure, soil-structure interactions and substructure method in which FEA is used for simulating the structural responses. Integrating an FEA program into various other software platforms in an efficient and simple way is crucial for the development and performance of the entire coupling system. The lack of simplicity of the existing integration methods makes this integration difficult and therefore entails the motivation of this study. In this paper, a novel practical technique, namely CS technique, is presented for integrating a general FEA software framework OpenSees into other software platforms, e.g., Matlab-$Simulink^{(R)}$ and a soil-structure interaction (SSI) system. The advantage of this integration technique is that it is efficient and relatively easy to implement. Instead of OpenSees, a cheap client handling TCL is integrated into the other software. The integration is achieved by extending the concept of internet based client-server concept, taking advantage of the parameterization framework of OpenSees, and using a command-driven scripting language called tool command language (TCL) on which the OpenSees' interface is based. There is no need for any programming inside OpenSees. The presented CS technique proves as an excellent solution for the coupling problems mentioned above (for both linear and nonlinear problems). Application examples are provided to validate the integration method and illustrate the various uses of the method in the civil engineering.

Continuous quality improvement is now the focus of research and application in quality engineering. To achieve continuous improvement, it's necessary to integrate quality tools and to plan, design and control the whole process of creating quality. Based on the extensive literature review and the philosophy of concurrent quality engineering, the paper analyzes the relationships among major quality tools such as QFD, FMEA, DOE and SPC and presents a basic model and structure for the integration of quality tools.

The maximum likelihood detection with QR decomposition and M-algorithm (QRM-MLD) has been presented as a suboptimum multiple-input multiple-output (MIMO) detection scheme which can provide almost the same performance as the optimum maximum likelihood (ML) MIMO detection scheme but with the reduced complexity. However, due to the lack of parallelism and the regularity in the decoding structure, the conventional QRM-MLD which uses the tree-structure still has very high complexity for the very large scale integration (VLSI) implementation. In this paper, we modify the tree-structure of conventional QRM-MLD into trellis-structure in order to obtain high operational parallelism and regularity and then apply the Viterbi algorithm to the QRM-MLD to ease the burden of the VLSI implementation.We show from our selected numerical examples that, by using the QRM-MLD with our proposed trellis-structure, we can reduce the complexity significantly compared to the tree-structure based QRM-MLD while the performance degradation of our proposed scheme is negligible.

Researches on a superstructure built on a floating structure in the shape of pontoon type have begun in recent years. A superstructure responds by wave load and it is important to evaluate its habitability. The purpose of this study is evaluation and investigation of habitability of a superstructure due to wave for 10 year return period. In this study, response analyses of the superstructure built on middle-sized floating structure due to the waves of three cases were carried out by 3-D integration analysis, which means analyzing the calculation model integrated a superstructure with a floating structure, and its habitability was evaluated by the evaluation diagrams. As the result, the habitability differed by each wave condition The use of a superstructure is restricted according to the disposition of a floating structure for incident wave angle.

The GPS/INS integration system navigation can provide improved navigation performance and has been widely used as a main navigation system for military and commercial vehicles. When two navigation systems are tightly coupled and the structure is complicated, a fault in either the GPS or the INS can lead to a disastrous failure of the whole integration system. This paper proposes a real-time fault detection method for an AGPS/INS integration system. The proposed fault detection method comprises a BIT and a fault detection algorithm based on chi-square test. It is implemented by real-time software modules to apply the AGPS/INS integration system and van test is carried out to evaluate its performance.

Three structure-dependent integration methods with no numerical dissipation have been successfully developed for time integration. Although these three integration methods generally have the same numerical properties, such as unconditional stability, second-order accuracy, explicit formulation, no overshoot and no numerical damping, there still exist some different numerical properties. It is found that TLM can only have unconditional stability for linear elastic and stiffness softening systems for zero viscous damping while for nonzero viscous damping it only has unconditional stability for linear elastic systems. Whereas, both CEM and CRM can have unconditional stability for linear elastic and stiffness softening systems for both zero and nonzero viscous damping. However, the most significantly different property among the three integration methods is a weak instability. In fact, both CRM and TLM have a weak instability, which will lead to an adverse overshoot or even a numerical instability in the high frequency responses to nonzero initial conditions. Whereas, CEM possesses no such an adverse weak instability. As a result, the performance of CEM is much better than for CRM and TLM. Notice that a weak instability property of CRM and TLM might severely limit its practical applications.

In this paper, we propose the building method for the unified IoT service platform between the variety of legacy systems with the heterogeneous structures and the operating environments. To accommodate the structural diversity of legacy systems, we develop a virtual integrated structure and interface abstracting method. By this, the new platform can use the data sources of the legacy systems as if the data source is in the new platform. In a manner without modification of the legacy systems with performing minimum tasks, we proposes a model that can be integrated without affecting the availabilities of the legacy systems.

본 연구는 해방 이후 현재까지 우리나라 중학교 사회과교육과정의 변천 과정을 정리하고, 그에 따른 지리교육의 목표와 내용 변화를 통합구조와 수준에 초점을 맞춰 분석하는데 목적이 있다. 연구 결과를 정리하면 다음과 같다. 첫째, 교수요목기부터 제3차 교육과정까지 중학교 사회과교육의 지리, 역사, 일반사회는 분과적으로 운영되었으나 제4차 교육과정에서 제7차 교육과정까지 중학교 사회과교육과정의 실질적 통합 요구가 강해졌다. 2007 개정 교육과정 이후 역사가 사회과교육과정으로부터 과목 독립하고, 학년마다 배치되었던 학제적 통합 단원도 사라지는 등 통합교과로서 사회과교육의 정체성이 흔들렸다. 그럼에도 불구하고 지리와 일반 사회만으로 구성된 중학교 사회과의 기형적 통합구조는 여전히 유지되고 있다. 둘째, 사회과 통합에 대한 요구가 강할수록 각 학문영역 간 시수 확보 경쟁 또한 치열해져 학습자의 학습 부담도 증가했다. 그리고 중학교 사회과 통합구조는 지리학과 지리교육의 간극을 점차 벌렸고, 지식과 학생 경험의 괴리도 넓혔다. 이처럼 중학교 사회과 통합구조는 지리교육과정의 목표와 내용 조직의 상위 요인으로 작용하여 의미 있는 지리교육과정을 개발하는데 걸림돌로 작용했다.

For the purpose of the efficient derivation of the closed-form Green's functions by which MoM matrix elements can be analytically evaluated, the optimum approximation path which is deformed from the Sommerfeld integration path on the complex $k_{\rho}$-plane is proposed based upon the steepest descent method and three level approximation procedure.
