This study aims to examine the integration process of educational system and school structure of the former East Germany into the Federal Republic of Germany following German unification. More specifically, the study focuses on drawing some policy suggestions and implications for achieving integration of South and North Korean educational system in a unified Korea. In fact, the school structure in the former East Germany had been integrated into West German educational system and school structure before and after official German unification by way of so called transitional process. The results of the study indicate that the integration process of school structure in the former East Germany into West German educational system was quite successful with stable management by means of various transitional measures and reaching an agreement between East and West Germany. Additionally, the study presents that local characteristics regarding school structure in the former East Germany were recognized and introduced in the integration process and they managed to handle the social change situation after German unification flexibly. However, it shows some shortcomings because it had been carried out in too short a period of time and the positive factors of school structure in the former East Germany had not been enough taken account into the integration process, along with the lack of inner comprehensive relevant infrastructure. Furthermore, the study points out that German case of school structure and its integration process after German unification has implications for specific ways Korea should pursue to achieve integration of South and North Korean educational system in a unified Korea. To be more specific, it suggests how we come up with plans and measures to establish integration of South and North Korean school structure in a stable way especially in terms of dealing with North Korean school structure and building an inner infrastructure.

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.

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.

This study aims to analyze the changes of goals and contents of middle school geography education following up the changes in the Korean social studies curriculum over time. The main findings are as follows. First, From the Syllabus period to the Third Curriculum, geography education, history education, general social studies education in the middle school social studies were directed and managed independently. However from the 4th to the 7th Curriculum, the demand for the virtual integration in middle school social studies increased sharply. Since 2009 revision, social studies suffered an identity crisis as integrated subject matter because history education was separated from the social studies and interdisciplinary units were abolished. In spite of much criticism, however, an odd form of social studies integrating geography and general social studies still remains. Second, the stronger the demand for the social studies integration in middle school, students' social studies learning load had become heavier due to severe competition with other areas to ensure more portion in the integrated structure of social studies. Since geography education did not reflect the new tendency of the geography in the integrated structure of middle school social studies, the gap between the geography and geography education has increased and knowledges of geography growing became separated from students' experience. In conclusion, the integrated structure of social studies in the middle school hindered the geography education development as it limited the autonomy of geography education in terms of curriculum development.
