The fusion type human resources, it is a new human resources to scientific and technical information society of the future demands, and means to enjoy life with a creativity and expertise of fusion of various fields, to communicate in consideration of others. Fusion human resource education(STEAM), of human resources to practice respect and compassion, human resources equipped with communication skills, human resources to pursue creativity and innovation human resources to understand the knowledge of the fusion to take advantage in training I have presented to the area of core competence of the 4C Creativity, Communication,Convergence, Caring. In this study, the area of c ore competency for each element by elementary, middle, and high schools around the analysis of the target can be made by each school level to develop a practical program in the sense of basic research is to conduct. The findings are as follows: First, Area of Creativity, communication area, the contents fusion region, as well as care areas, to the detailed item capacity, the design of the class that contains the entire area should be performed. Second, Elementary and secondary school level analysis, design of the class containing the entire region up to capacity detail is required. High school was required study of school full of normal. Third, In general, for STEAM class environment and teaching model was developed by applying operations. Research and methods of teaching a wider variety of form was required. Later in this study is to develop programs and organize. and It intends to become the base to be able to interest and interest in science education by structured around the status of problems that can be found in the life of around themes STEAM.

ASR 기법을 적용한 임무지향 교전통제 컴퓨터의 신뢰도 분석
신진범,김상하,Shin, Jin-Beom,Kim, Sang-Ha 한국정보처리학회 2008 정보처리학회논문지 A Vol.15 No.6
대공방어용 임무지향 교전통제 컴퓨터는 장시간 동안 임무의 중단없이 방어 임무를 수행하여야 하며, 복잡한 내장형 임무 소프트웨어를 탑재하는 컴퓨터에는 대공방어 임무의 특성상 확실성과 안정성 및 신뢰성을 보장하여야 한다. 구현된 임무지향 교전통제 컴퓨터에서 임무수행의 확실성과 안정성은 4 장의 프로세서로 구성되는 분산 컴퓨터 아키텍처에 의해 보장되며, 신뢰도는 분산 구조의 컴퓨터에 저비용의 능동 예비 이중화(ASR) 고장감내 기법을 적용하여 보장되도록 하였다. 소프트웨어적인 능동 예비 이중화 고장감내 기법은 높은 신뢰도와 신속한 고장복구 성능을 가지는 교전통제 컴퓨터를 저비용으로 구현하므로 대공방어용 컴퓨터에 매우 적합한 기법이다. 본 논문은 능동 예비 이중화 고장감내 기법의 메커니즘과 성능분석에 대해 기술하고, 교전통제 컴퓨터에 ASR 기법과 하드웨어적인 DMR 및 TMR 고장감내 기법을 적용한 경우의 MTBF, 신뢰도, 가용성 및 저비용성을 비교분석하였다. ASR 기법은 72 시간의 임무 시간에 대하여 TMR과 유사한 임무 신뢰도를 제공하며, 저비용의 구현이 가능하므로 교전통제 임무지향 컴퓨터의 고장감내 기법으로 최적인 것으로 분석되었다. The mission-critical engagement control computer for air defense has to maintain its operation without any fault for a long mission time. The mission performed by large-scale and complex embedded software is extremely critical in terms of dependability and safety of computer system, and it is very important that engagement control computer has high reliability. The engagement control computer was implemented using four processors. The distributed computer composed of four processors quarantees the dependability and safety, and ASR fault-tolerant technique applied to each processor guarantees the reliability. In this paper, the mechanism and performance of ASR fault-tolerant technique are analysed. And MTBF, reliability, availability, and cost-effectiveness for ASR, DMR and TMR techniques applied to the engagement control computer are analysed. The mission-critical engagement control computer using software-based ASR fault-tolerant technique provides high reliability and fast recovery time at a low cost. The mission reliability of the engagement control computer using ASR technique in 4 processors board is almost same the reliability of the computer using TMR technique in 6 processors board. ASR technique is most suitable to the mission-critical engagement control computer.

확장 ASR 기법을 이용한 임무지향 컴퓨터의 설계 및 신뢰도 분석
신진범,김상하,Shin, Jin-Beom,Kim, Sang-Ha 한국정보처리학회 2009 정보처리학회논문지 A Vol.16 No.4
대공방어용 임무지향 컴퓨터는 장시간의 대공방어 임무를 성공적으로 완수하기 위하여 고장감내 기능이 필수적으로 요구되며, 고장감내 기법으로는 지상 장비인 임무지향 컴퓨터에 적합한 저비용의 기법이 요구된다. 현재 기본형의 임무지향 컴퓨터에는 저비용의 ASR 고장 감내 기법이 적용되어 있으나, ASR 기법은 TMR 기법을 적용한 컴퓨터에 비해 낮은 임무 신뢰도를 제공한다. 그러므로 본 논문에서는 TMR 기법을 적용한 컴퓨터 보다 적은 수량의 프로세서 보드를 사용하여 우수한 신뢰도를 제공하는 확장형 ASR(EASR) 고장 감내 기법을 제안하였으며, 제안된 EASR 기법 을 적용한 임무지향 컴퓨터의 고장 감내 성능을 입증하였다. EASR 기법의 임무지향 컴퓨터는 고장 감내 성능과 저비용성 측면에서 대공방어 시스템의 컴퓨터에 적합하였다. The mission-critical computer for air defense has to maintain its operation without any fault for a long mission time and is required to implement at low cost. Now the reliability of the mission critical-computer using Active Sparing Redundancy fault-tolerant technique is inferior to that of the computer using TMR technique. So in this paper are proposed Extended ASR(EASR) technique that provides higher reliability than that of the computer using TMR technique. The fault-tolerant performance of the implemented mission-critical computer is proven through reliability analysis and numbers of fault recovery test. Also, the reliability of the mission-critical computer using EASR technique is compared with those of computer using ASR and TMR techniques. EASR technique is very suitable to the mission-critical computer.

We proposed a design method for squib current supply & interlock circuits in guided-missile fire control systems. In order to design squib current supply circuits, various missile squib loads including line resistance and squib devices have to be considered in advance minimizing probability of redesign of circuits and reducing the development cost by implementing the most proper squib current supply circuit. Also, we presented a hardware interlock logic instead of the commonly used software safety logic to improve the safety of guided-missile fire control systems. The proposed squib interlock circuit enhances safety requirements of guided-missile fire control systems. We confirmed that simulation and measurement results of the proposed design method are the same as theoretical analysis results.
