Supply in military operations has a significant impact on overall combat capability and efficiency. Therefore, modernization of military logistics is underway to ensure rapid and accurate distribution. And, effective warehouse management is paramount. This paper proposes a new product allocation model that uses a genetic algorithm. The model considers order frequency and mass of products because the military equipment is usually heavier than available products. A computer simulation shows that products are assigned to optimal locations and reduce the consumed energy for forklifts by more than 25 % with similar travel time. Also, we show the superiority of genetic algorithm by comparing them with other algorithms.

유비쿼터스 핵심 기술 중 하나인 RFID 기술은 의료산업분야 전반에 걸쳐 활용이 증가하고 있으나, RFID 기술은 태그의 내용을 리더기를 통해 무선주파수로 식별하는 기술임으로 태그의 크기와 위치에 따라 태그의 인식률에 대한 차이가 크기 때문에 태그의 인식률의 성능이 입증되지 않아 도입의 큰 어려움을 겪고 있다. 본 연구에서는 사물의 다중인식이 가능한 RFID 시스템을 의약품 창고 관리에 적용하기 위하여 병원 내에서 사용하는 기밀용기에 대한 태그 부착위치와 크기에 대한 인식률 연구를 수행하였다. 실제 병원 약제실의 책장을 모델링하여 Test Bed로 구축하였으며, 구축된 Test-Bed를 통해 병원에서 사용하는 의료용 기밀용기에 태그를 부착하여 최적의 위치를 찾고, 리더기의 최적의 위치에 대한 연구를 수행하였으며, 인식률 향상을 위한 최적의 조건을 제공하고자 한다.

The problem of selecting base station location in the design of mobile communication system has been basically regarded as a problem of assigning maximum users in the cell to the minimum base stations while maintaining minimum SIR. and it is NP hard. The objective function of warehouse location problem, which has been used by many researchers, is not proper function in the base station location problem in CDMA mobile communication, The optimal and approximate solutions have been presented by using proposed object function and algorithms of exact solution, and the simulation results have been assessed and analyzed. The optimal and approximate solutions are found by using mixed integer programming instead of meta-heuristic search methods.

The next generation Web 2.0 users are requiring a screen that satisfies visual and emotional factors regarding UI and the possibility of constant recognition about various information. To actively deal with these kinds of user demands, dual cooperation between the developer and designer is becoming more urgently needed. For this, Microsoft released Silverlight, a tool for when making a web presentation that enables persons to create a visually stunning webpage using diverse platforms and function. We applied clarity and animation to existing windows concepts, using Silverlight with which designers and developers can work together and is accessable to many development tools, and provided 3D effects to implement a Warehouse Management System.

This study suggests surface wave communication, which uses a metal surface as a medium, to provide wireless communication in the extreme environment due to surrounding metal materials on vessels. The test was conducted on a G/T 265 tons tug boat to confirm the possibility of surface wave communication between a bridge and each designated space in the ship. As a result, the transmission speed was 13Mbps on average. In a test case of the bridge via the engine room, the transmission speed was 4.3Mbps on engine running and 1.2Mbps on sailing. It overcame this by partially changing the equipment installation location. Surface wave communication in bow storage, a fully enclosed space, had 8Mbps better transmission speed than wireless communication; this confirmed the superiority of surface wave communication in confined spaces on a vessel. Additional surface wave generators were designed and applied to resolve the paint issue. It is expected to use surface wave communication to implement the new wireless solution for Maritime-IoT system on vessels.
