Recently, E-Commerce demands an integrated solution for online and off-line provided to customers on wired / wireless network and various mobile devices. Our E-commerce platform can use anytime, anywhere, for all consumers. And, it can take convenient and secure E-commerce service in mobile environment. So, we will implement a software platform base on the mobile environment that independent of the mobile OS. Particularly, our E-commerce platform is based on 3D GIS information for 3D electronic map. So, all users (customers) have got the more visible convenience. And, by using the e-catalog DB cloud server, off-line store operators can be built the online home-page easily. From now on our E-commerce platform based on 3D GIS can be usable at various E-commerce areas in the ubiquitous environment.

본 아키텍처(IDPS)는 현 해군 수상함 전투체계의 함정별 소프트웨어 진단 도구를 통합하여 진단 방식의 일관성과 효율성, 진단 소요 시간의 감소를 달성하기 위한 웹기반의 플랫폼을 구축하는 구조적 방법이다. 함형 별 구분된 독립적인 진단 방식으로 인하여 수명주기지원(LTS) 시 인력 운용 측면의 비효율성과 진단자의 숙련도 등에 따른 진단 품질의 차이가 발생하기 때문에, 함정 SW 상태를 진단하는 방식을 함형에 구분없이 일원화하고 진단자에 따른 진단 결과의 편향과 오차가 발생하지 않도록 진단데이터를 플랫폼에 내재된 상태결정알고리즘(SDA)에 의해 판정하도록 지능화하였다. 장기적으로 수상함 전투체계 소프트웨어의 진단에 있어 진단 품질의 하락없는 사람 개입이 최소화된 지능화된 시스템 구축을 추구하며, 이를 통해 진단 소요 시간을 단축하고 진단 결과의 활용에 더 많은 자원을 투입할 수 있을 것으로 기대된다.

Because the existing BIM platform is based on user services, the focus is on the development of SaaS (Software as a Service), which provides business services online. However, since a harbor is a security facility, the harbor BIM platform is preferably provided in a private form, rather than relying on the infrastructure environment provided by external cloud providers. Therefore, this study analyzes and reviews the main functions to be provided as SaaS services of the harbor BIM platform. The goal is to build a cloud-based harbor BIM platform that can provide this service to users. To this end, we built IaaS (Infrastructure as a Service) environment of the harbor BIM platform based on the open source Open Stack and integrate and develop PaaS environment with Open Shift applied with IaaS. We applied the GPU to the harbor BIM platform to verify the performance of the harbor BIM platform, and found that the rendering and loading times are improved. In particular, it is expected to reduce the cost of introduction and provide it as the basic cloud environment of similar BIM platform for infrastructure facilities.

Because of the demands for high performance and high integrated system, the needs for optimal platform becomes more importance. Optimal platform can handle more data effectively with same resources. AMBA(Advanced Microprocessor Bus Architecture)$^{TM}$ defines on-chip communication standard for designing high performance embedded micro-controllers. It is consisted of AHB, ASB and APB. It can support fast implementation and reliability in system that is composed with reusable IPs. DMAC is one of master in system and generate master signals of AHB to communicate data from one slave(peripheral or memory) to another slave. It can reduce burden of CPU and increase system performance. We designed DMAC based on AMBA and it supports 13 Channels. Each channel can be controlled by software program. It decides channel's priority using round-robin method. It can support P2P, P2M, M2P and P2P communication.

A growing number of large scale knowledge graphs raises several issues how knowledge graph data can be organized, discovered, and integrated efficiently. We present a novel semantic-based mashup platform for contents convergence which consists of acquisition, RDF storage, ontology learning, and mashup subsystems. This platform servers a basis for developing other more sophisticated applications required in the area of knowledge big data. Moreover, this paper proposes an entity matching method using graph convolutional network techniques as a preliminary work for automatic classification and discovery on knowledge big data. Using real DBP15K and SRPRS datasets, the performance of our method is compared with some existing entity matching methods. The experimental results show that the proposed method outperforms existing methods due to its ability to increase accuracy and reduce training time.

Software-In-the-Loop Simulation(SILS) and Rapid Control Prototyping(RCP) are proposed as an integrated development environment to support the development process from system design to implementation. SILS is an environment used to simulate control systems with temporal behavior. RCP offers seamless phase shift from design to implementation based on automatic code generation. There are several toolsets that support control system design and analysis. A few of these tools generate the control software automatically. However, most of these design toolsets do not cover temporal behavior which appears after implementation. In earlier toolsets, the design and the implementation of a control system are considered as two separate processes which mean the conventional development process is not connected strictly. SILS/RCP environments work under an identical platform and use the same representation for system modeling. An integrated SILS/RCP environment makes it possible to design controllers under conditions similar to real execution during off-line simulation and to realize controllers in the early design phase. SILS/RCP environments integrate the design and implementation phases which reduce the time-to-market and provide greater performance-assured design. The establishment of SILS/RCP and the practical design approaches are presented.

We address an integrated multimedia framework based on a software agent platform for context-aware multimedia computing. We adopt the FIPA (Foundation for Intelligent Physical Agents) platform which provides agent communications and management mechanisms. In order to express context information, we use MPEG-21 metadata for describing user characteristics and usage environment. We encapsulate such context information as a FIPA message to be delivered between agents. Based on context information, appropriate multimedia content delivery becomes possible. We present our system implementation with a use case scenario and show that our proposed framework is effective for context-aware multimedia computing so that personalization of multimedia consumption can be possible.

Embedded system developers use design and testing tools to make their product faster. Previously developed a virtual development environment for embedded software (VDEES) using open source software, mainly the SID simulation framework for a simulator engine and the Eclipse platform for a development platform. VDEES enables developers to develop SID Component in C++. A bridge module for developing SID Component in Java has been developed and available. However, using this module, developers have to build their SID Java component from scratch. In this work, we developed SID Java Component Builder Plug-in as an additional features to VDEES. This tools enables developers to build SID Component in Java faster and easier.

본 논문에서는 SIW(Substrate Integrated Waveguide) 구조를 갖는 SDR(Software Defined Radar)용 안테나를 설계하고 제작하였다. SIW 구조는 쉬운 집적화로 인하여 일반 PCB 상에 구현이 가능하고, 기존의 구형 도파관과 같이 높은 전력의 입력 신호에 대하여 낮은 전송손실을 가지는 특성이 있다. 또한, 전자기 간섭에 대하여 강한 내성을 갖는 장점이 있다. 특히 본 논문에서는 제작한 SIW 안테나를 가지고 USRP(Universal Software Radio Peripheral) 플랫폼에 탑재하여 목표물 RCS(Radar Cross Section)탐지 실험을 진행하였다. 제안된 안테나는 ISM(Industrial, Scientific and Medical) 대역(2.4~2.48 GHz)에서 동작하며, 이득 특성은 8 dBi 이상을 보인다.
