A tangible floating display that can provide different perspective views without special glasses being introduced. The proposed system can display perspective floating images in the space in front of the system with the help of concave mirrors. In order to avoid wearing special equipment to interact and deliver the sense of touch, the proposed system adopted an ultrasound focusing technology. For providing an immersive experience to the viewers, the proposed system consists of a tangible floating display system and a multiple-view imaging system for generating three lenticular displays in front of the users.

This paper deals with a design of a platform to simulate PRT vehicle operational control algorithms using on-board embedded process board. The configuration of the platform is composed of the central control module, the station control module, man-machine interface and monitoring module. Since PRT system needs inherently very reliable vehicle operational control algorithm in order to avoid the impact between vehicles, it is very important to construct a simulation platform to test a designed vehicle operational control algorithm during the development process For the test of the proposed platform a path of the each moving vehicle is predefined in the central control system before the dispatch order is given to the vehicle. The simulation results show the effectiveness of the proposed simulation platform for test and evaluation of the PRT operational control algorithms.

Platform standardization is widely used in commercial auto industries and other industries to acquire cost reduction as well as high reliability. This paper reviews some application examples and estimates expected effect of Korean army's platform standardization for combat system and combat support system. Also, military platform standardization based on utilization of commercial vehicles has been studied with the standard vehicles used in Korean army. It is estimated that outstanding results may be achieved if a dual platform, the public and military platforms, is utilized. So, when the strategy of the military transportation system is decided, "dual use" concept is necessary and this could maximize the effect of the military strategy reinforcement.

For avoiding the waste of costs for building each mobile platform according to each mobile communication vender, KWISF proposed WIPI platform standard. Already the venders are providing mobile map services which are adapted on their own platforms. Because the integration of various mobile platform was performed to WIPI standard, the changes of platform and component API may cause the environment changes of mobile nap services. This study shows the design and implementation results of mobile map services adapted to WPI environments.

본 논문은 Platform 기반의 PEBB(Power Electronics Building Block)을 이용한 계통연계형 에너지저장시스템(ESS) PCS의 개발전략과 효율적인 운용 방법에 대해 제안한다. Platform Design이란 표준제조 공정을 통해 다양한 제품을 만들어 내는 기술을 뜻한다. 이 Platform으로 생산되는 Modular PEBB(Power Electronics Building Block)을 이용하여 다양한 용량대의 제품에 대응할 수 있으며, 이를 통해 125kW에서부터 2MW제품까지 병렬확장이 가능하다. PCS의 Platform화로 시스템 용량 확장이 용이하며, 대량 생산이 가능하기 때문에 비용 측면에서의 장점이 있다. 그리고 부분 운전을 통해 운영 효율 향상과 PCS 수명을 늘릴 수 있다. 본 논문에서는 Platform 기반의 PCS의 물리적 및 제어적 구조를 설명하고, 개발전략의 방법에 대해 소개하고자 한다.

Recently, the blockchain platform is changing the art market. Changes are taking place in many areas, including artists, collectors, art investors, and auction. The platform that provides distribution history information on artworks on a blockchain basis can be used when information on the work history is suspected or needs verification, and can be used to manage the distribution history information of stolen and lost artworks and confiscated artworks by the police. Several companies currently operate these platforms, but they operate various blockchain platforms according to their contents. In this paper, we will compare and analyze features of artworks blockchain platform.
