As part of the integration phases in developing a UAV, a System Integration Laboratory (SIL) has been developed to provide integrated test capability for the verification of avionics system requirements. The SIL has realized primary functions that are common in manned aircraft SIL's, and specialized laying stress on test data visualization and test automation under the closed-loop structure of the ground control simulation, aircraft simulation and flight simulation components. Those design results have led to easy and sure verification of lots of complex requirements of the UAV avionics system. The functions and performances of the SIL have been proved in four gradational test steps and checked to operate successfully in aircraft System Integration Test Environment for the integration of UAV ground station and aircraft.

Cellular Automata(CA) have been investigated and utilized as a theoretical framework and/or methodology for analyzing and simulating the properties and behaviors of many complex systems in various physical science and engineering field. Due to the conceptual elegance and effectiveness of implementing spatio-temporal dynamic models and the compatibility with raster GISs, recently a variety of modeling works using both CA and GIS have been published in GIS fields Most of spatial dynamic models introduced in previous research, however, were very limited and furthermore integrated CA-GIS system for practical modeling purpose are not developed yet. This study aims to develop an integrated CA-GIS system in which a CA simulator is used as an analytical engine for GIS providing a multipurpose spatial dynamic modeling functionalities. This integrated CA-GIS system is anticipated radically enhancing the current lacking dynamic modeling functionalities of GIS and being utilized as an powerful and effective tool for practical spatial dynamic modeling research.

Recently, environment facilities are able to manage real-time data collection and record management through integrated broadband modem LAN switching technology. Therefore, it need more stable and efficient facility management. So, we required practical use of environmental facilities convergence based on broadband integrated modem. In this paper, we proposed an integrated broadband modem LAN switching technology which can applicable to the environment facility. Also, we presented integrated broadband modem of design plan and communication system. And it received data inside of environment facility using the two communication methods(IEEE802.11x and IEEE802.15.4x). Then, our proposed integrated broadband modem LAN switching technology will prioritize processing data when emergency happen through collecting data, analysis data and processing. Lastly, we proved usefulness by experiment and simulation analysis.

현대 디자인 분야에는 건축이나 제품, 의복 등에까지 투명성이 디자인의 매우 중요한 요소로 활용되고 있다. 아름다우면서도 기능성과 견고함을 지닌 투명한 재료들이 과학기술의 발달에 힘입어 속속 개발되고 있으며, 또한 투명성 디자인은 현대 디자인의 트랜드인 즐거움과 유희 등을 표현하는 감성 트랜드와 잘 부합되기 때문이다. 본 연구는 이러한 시대의 흐름에 발맞추어 사용자들에게 재미와 즐거움의 가치를 감각적인 부분과 통합할 수 있는 디자인 개발에 목적을 두고, 20세기 후반부터 트랜드의 커다란 부분을 차지하고 있는 투명성을 좀 더 재미있고 여성스러운 감성을 자극할 수 있는 새로운 재해석의 방향을 찾아 패션 디자인을 제안하고자 한다.

RSVP was published as a resource reservation protocol to guarantee QoS for realtime applications in wired network environments. As mobile application services in wireless network environments are more popular, QoS guaranteeing problem becomes an important issue in mobile computing environments. Therefore, the researches about cooperation between RSVP and Mobile IP supporting mobility in mobile computing environments are activating today. In this paper, we propose I-MRSVP(Integrated-Mobile RSVP), a QoS guaranteed resource reservation protocol supporting the integrated mobility in mobile computing environments. I-MRSVP protocol supports the integrated mobility providing interoperability between Mobile IP-based macro cells and Cellular IP-based micro cells. To minimize resource reservation overheads, it provides efficient resource reservation functions by using the signal strength based predictive resource reservation scheme.

최근 기업환경에서는 분산되어 있는 정보를 통합하여 정보 공유의 필요성이 증가함에 따라 기존 레거시 시스템간의 협업을 하기 위한 상호 운용이 강조되고 있다. 독립적인 레거시 시스템의 상호 연결을 위해서는 플랫폼 이질성, 의미 이질성 등을 극복할 필요가 있다. 이러한 문제를 해결하기 위해 ISO/IEC 11179에서 진행하고 있는 XMDR을 이용하여 미들웨어를 설계하였다. 설계한 미들웨어를 레거시 시스템에 적용하여 데이터 공유 및 통합의 일관성을 유지할 수 있게 되었다. 하지만 설계된 미들웨어는 각 노드의 자원 상황과 작업 상황에 대한 조정기능이 없기 때문에 정보 활용의 효율성을 보장할 수 없다. 따라서 레거시 시스템을 관리하고 조정하는 방안이 필요하다. 본 논문에서는 정보를 요청하는 요청 에이전트와 정보를 제공하는 정보 에이전트간의 정확한 정보 교환을 할 수 있도록 조정하고, 각 레거시 시스템의 정보 모니터링과 작업 분배 및 로컬 노드의 자원 관리를 담당하는 협력 에이전트를 설계함으로써 통합된 정보를 효율적으로 활용할 수 있도록 한다.

Digital-ship is the next-generation ship with an one-man bridge system which consists of INS(Intelligent Navigation System), AIS(Automatic Identification System), and IMIT(Integrated Maritime Information Technology). INS implements the functions is related of the ship's navigation, and supports in the digital GIS environments optimal route planning, stranding and a collision avoidance among the ship, an economic navigation, and an integrated control of ship's engine. AIS prevents the ship's collision by means of transmitting periodically the own ship's information to the other ship or the shore control center. IMIT systems supports the integrated fiat-form in ships, the communication between a ship and a control center of the land using the INMARSAT, OrbComm, Ocean Observation Satellite, and etc. The satellite communication in ships can monitor the ship at an earth control renter. This paper deals with the method for system implementation of digital-ship and the detailed sub-system.

This study compares the space depth and layout of a modern apartment floor plan (MAFP) and the standard floor plan of traditional Korean houses (STKHs), which has preserved the traditional beauty of Korea. Space Syntax was applied to compare the MAFP and STKH. The space within MAFP was more divided into many spaces than the STKH. In both types of floor plans, the living room space had the highest degree of integration and was used for central functions in the each floor plan. The STKH and the space in the MAFP have more segregated space than integrated space. In the STKH, the master bedroom and other rooms were found to be segregated space. However, the master bedroom of the MAFP was highly integrated space. The function of the thet maru has been greatly reduced in the STKH, and the numaru was classified as a highly segregated space. The evacuation space was the most segregated space in the MAFP. The STKH has been adapted and changed according to the trends of the times, and the MAFP reflects our traditional living habits.

Recently, BIM(Building Information Model) is widely applied to all stages of SOC (Social Overhead Capital)facilities life cycle from planning to maintenance. While BIM is an analysis tool focussing the inner space of facilities, GIS is principally applied to analyzing relationship between facilities. Therefore, integrating BIM and GIS, we expect to get a potential synergy effect in aspects of effective information management and various analysis for SOC facilities. This paper deals with prioritizing SOC facilities for applying BIM/GIS integrating platform to local governments. First, investigate facilities required by law, and identify SOC facilities suitable for SOC characteristics. Second, analyze the effectiveness and applicability of BIM/GIS integrating platform applying each facility. For the purpose, we quantify effectiveness and applicability in aspects of UIS management and GIS functions. Lastly, prioritize the SOC facilities applying BIM/GIS integrating platform.

The Next generation network may describe one integrated network by IP (Internet Protocol) convergence and combining various access technologies. The IP version 6 (IPv6) becomes fundamental protocol and the terminal offered various services is having mobility, multihoming, and intelligent as well as smaller. In this convergence network, which integrate mobile network, broad cast network, and Internet as well as PSTN, can provide all of the service. In this context, we will briefly present that the end node should be required ubiquitous computing and networking. That is to say that we must guarantee the end node in any time, my place, my where, and offer continuously services to the node. As like this, Service Mobility is given if a user can obtain subscribed and personalized services consistently even if connected to a foreign network service provider. In other words, Service mobility allows users to maintain access to their services even while moving or changing devices and network service providers. In this paper, we have to refer technical consideration items to make the service mobility framework.
