  • 본 논문에서는 스마트 시대에 ETRI 전망 비전 2020에서 제시한 4S전략(Smart, Safe, Strong, Sustainable)을 바탕으로 Beyond Smart 시대의 Safe 전략을 제안해 보고자 한다. Smart한 국가기반과 Strong한 경쟁력을 갖추는 것, 그리고 Safe한 국가 질서를 유지하는 일과 Sustainable한 국가 환경을 유지하는 일이 상호 독립적으로 달성될 수 있다는 전제이다. 그런데 문제는 이러한 목표들을 어떻게 달성할 것인가 하는 전략(strategy)의 문제이다. 10대 IT 아젠다에서의 Safe 전략은 물리적 안전과 심리적 안전을 보장하는 안심/안전, 고령화 사회를 대비한 건강 장수국가와 요람에서 무덤까지 안전한 교통 선진국가 등 3개 아젠다로 도출하였다. 10대 IT 아젠다에서의 Safe 영역을 튼실하게 구축하는 경우, 미래의 우리나라는 건강하고 안전한 선진국 대열을 선도하는 국가로 태어날 수 있을 것이다.

  • According to the characteristic of carrier-based aircraft, the method of solving safe set during arresting landing is discussed in this paper based on optimal control and invariant set theory. The safe sets of carrier aircraft are evaluated in different states on the characteristic of longitudinal augmented system by using the level set method. Then, the influence on the boundary of safe set under various factors is analyzed. At last, the maneuverability envelope protection is established based on the corresponding theory, and the validity of the system is verified through simulation. The results demonstrate preliminarily that: compared with mass and thrust, the elevator is the greatest influence factor for the boundary of safe set; the dynamic trajectory of carrier-based aircraft can be located at the interior of safe set effectively with the maneuverability envelope protection.

  • The purpose of this study is to establish the function of a sub-system for System Alternatives Feasibility Estimation (SAFE) in R & D Project Planning Phase (RDPPL). It is the fundamental function of the RDPPL/SAFE that selected an optimal planning system alternative of all, considered at RDPPL/SAS, by logical means in view of feasibility. In this paper, improving the function of RDPPL/SAFE, mathmatical models in order to quantify methods determining and integrating the feasibility funtion in each terminal system with a multi-stage process are examined.
