This paper investigates an efficient transmission scheme for the remote wireless sensors to receive information which is rarely discussed in the integrated remote wireless sensor and multibeam satellite networks (IWSMSNs). The networks can be employed to exchange sensing information for emergency scenario, ocean scenario, and so on, which are isolated from available terrestrial networks. As the efficient transmission link is important to the IWSMSNs, we propose a hybrid full frequency (HFF) precoding by taking advantage of frequency reuse and multiple-input multiple-output (MIMO) precoding. Considering energy efficiency and sinks fairness are crucial to transmission link, thus the HFF precoding problems are formulated as transmit power minimization (TPM) and max-min fair (MMF) received signal to interference plus noise ratio (SINR) problems, which can be transformed to indefinite quadratic optimization programs. Then this paper presents a semi-definite programming (SDP) algorithm to solve the problems for the IWSMSNs. The promising potential of HFF for the real IWSMSNs is demonstrated through simulations.

Recently Korea Army developed the TICN which is the next army tactical communication system. The TICN will support ability from under environment, strategy maneuver communication system of integrated army dimension overcome and NCW. If the IER(Information Exchange Requirement) phases 3 of the future application system, the analysis that a transmission ability of the TICN is the uncapable is govern. The TICN tactical backbone's ability is very important. Therefore, network efficiency index in application and analysis of the standard protocol for the data transmission guarantee are obliged. For the TICN tactical backbone, this paper analyzes of routing protocol efficiency index and compares to superiority of the OSPF(v2) and integrated IS-IS protocols in the tactical environment. Conclusively we proposed that integrated IS-IS protocol is more suitable for TICN backbone routing protocol.

Nowadays, as the increasing functionality and scales of embedded systems, system design grows more complex than before. So verification and simulation of systems become an important facet in hardware-software co-design issues. But it is almost impossible to simulate an embedded system without real hardware implementation or environment communication, especially for control-dominated reactive systems. Therefore, in this paper, we will introduce a GUI environment module generator for integrated Esterel\C++ simulation. By generating the GUI modeling environment, we can simulate and verify the whole embedded system conveniently.

We present the motivation, design and implementation of a smart home system in Korea. Our system is open, extensible, integrated, intelligent, and usage-centric. We detail the challenges and key design requirements for the smart home system based on our past experiences, and show how convergence system design is a capable methodology for enabling an integrated and multi-faceted home management system that encompasses energy management, home appliance control, environment management, u-health, and living support functionalities under a single unified design. Using energy management as a specific case study, we demonstrate how convergence system design can encapsulate technology heterogeneity and hardware-software disparity without compromising simple yet powerful user interfaces.

We have studied the methods to connect homes with a digital network and apply home automation to education. We presented the possibility of integrated education where public education at school can be extended to home. The hardwares related with home automation are continuously in development. We have demonstrated the materials appropriate for the levels of individual students with home network information, and studied methods of education.

In the case of an agile-based project, it was inadequate to perform a comprehensive inspection and evaluation on the establishment and operation of an information system by performing audit only with the audit and inspection elements provided by the existing information system audit and inspection system. In particular, in the case of the test activity area, it was necessary to improve the test activity audit check items to comprehensively check the agile-based development process by applying the existing audit system. To this end, a test activity improvement check model of the agile methodology audit model was presented by applying the repetition concept, a characteristic of the agile methodology. In order to empirically verify the model of this study, a survey was conducted for auditors and designers/developers who have experience in performing agile-based projects and auditing information systems. As a result of the questionnaire on the integrated test and system test in the test stage, more than 70% of the respondents were found to be suitable. More than 80% of the respondents judged that it was appropriate as a result of the questionnaire on "improvement and regression test progress according to integrated test and system test results" and "integrated test and functional actions of components and subsystems".

본 논문에서는 최초 제품의 생산에서부터 최종 소비자에 이르기까지의 전 과정에서 RFID 시스템을 이용하여 조달, 설계, 제조, 보수, 폐기의 각각의 단계별 u-Logistics 설계 및 DB통합을 통한 Integrated u-logistics 설계 방안을 제안한다. 제안한 시스템은 단계별 수집된 정보를 기초로 하여 제품 생산과정부터 소비자에게 전달되기까지의 전체 제품의 life cycle을 한곳에서 관리할 수 있기 때문에 능동적이며, 효과적인 재고 관리, 인력 관리, 수요 예측, 판매 성향 분석 등이 이루어 질수 있다. 이는 단순한 유통과정만을 관리하던 기존의 물류시스템과는 확연한 차이를 보여준다.
