  • 현재 해군에서 추진중인 전투체계사업을 정보통신산업의 육성과 연계시킨다면 우리의 기술수준을 한단계 올려 놓을수 있을 것입니다. 공군의 KFP사업을 우리나라 항공기산업 육성의 발판으로 삼고 추진하는 것과 같이 해군의 전투체계사업을 정보통신산업 육성의 발판으로 삼는다면, 정보통신 기술발전을 계획하고 있는 우리나라의 입장에서 볼때 정보통신산업가 관련된 기술기반을 획득할수 있는 좋은 계기가 될 것입니다

  • 최근 수요가 급증되고 있는 u-City의 경우 성공적인 구축을 위하여 도시통합운영센터라는 개념을 도입하여 추진하고 있으며, 나아가 이를 보다 확장시킨 개념인 도시통합운영체계의 중요성이 강조되고 있다. 이처럼 u-City의 핵심기반으로서 도시통합운영체계의 중요성이 증대되고 있는 가운데, 효율적인 도시통합운영체계 구축을 위해선 공간정보 활용이 필요하다. 즉, 지자체에선 오래전부터 GIS 정보화 사업을 추진하고 있으며, 공간정보를 구축 활용하고 있다. 효율적인 도시통합운영체계 구축을 위해선 공간정보의 활용은 필수적이며, 이는 u-City 추진의 핵심적 기반이 될 것이다. 본 연구에서는 u-City 도시통합운영체계에서 공간정보를 효율적으로 활용을 위해 u-City의 도시통합운영서비스와 관련하여 공간정보의 활용성과 활용방안을 제시하고자 한다.

  • The purpose of this paper is "A Study on the Establishment of Distribution and Logistics System in the unified Korea". The main conclusion of this paper are as follows : North and South Korea shall conjunctionally foster the exchange and cooperation area and operate the joint pilot project to combine distribution and logistics system. To solve the problems of the maritime affairs, Fisheries, and international logistics, the cooperative agreement between North and South Korea will be needed to protect and develop of shipping, aviation and shipbuilding industry. Unification of two Koreas must be prepared as stage by stage ; ${\cdot}$Stage1(preparation period) : initiation of peace area. ${\cdot}$Stage2(development period) : forming the exchange and cooperation area ${\cdot}$Stage3(settlement period) : establishing peace belt on border area. After the unification, two Koreas must plan and undertake the construction of the distribution and logistics infrastructures, establishment of SCM system through Network and the connection to China through railway and road Network.

  • Developing model to predict the characteristic of vented gas was vented through an orifice is presented. Simulations with models which were developed with assumptions considering heat transfer inside the vessel were conducted. Also, representative pressure and temperature were measured from experiments with the pressure vessel which is applicable to a propulsion system. Developed model were verified with comparison between calculations and experiments.

  • Developing a model was carried out to predict the characteristic of a pressure vessel from which the gas was vented through an orifice. An experimental test was conducted on a pressure vessel applicable to a propulsion system so that representative pressure and temperature were measured. Simulations were conducted with models using assumptions considering heat transfer inside the vessel, and the results were compared to those from the experiment. As a result, it was found out that a proposed heat transfer model was proper to predict pressure and temperature of the vented gas comparable to the measured data.

  • This paper describes the design of model-based fault diagnosis software to apply to the propulsion system in tracked amphibious assault vehicle which consists of an engine, a transmission, a cooling system, and two waterjets. This software includes specific functions to detect the failures regarding sensor malfunctions, mechanical malfunctions, control errors, and communication errors. This software generates the proper malfunction codes which are classified as the warning and caution. In order to validate the fault diagnosis software, the manual and automatic test are performed using the test program with 32 test cases. Test results show that the designed fault diagnosis software is reliable and effective for applying to the propulsion system.
