차세대 항공전자 시스템은 표준화 모듈의 데이터통신에 기반한 개방형 아키텍처와 범용성을 위한 새로운 시스템 개발이 요구된다. 본 논문에서는 차세대 항공전자 비행운영 프로그램을 지원하기 위한 메시지 기반 미들웨어를 설계하고 이에 대한 구현 및 테스트를 통한 적용성을 검증한다. 시스템 구성은 임무컴퓨터 (Mission Computer, MC)와 대화면 시현기 (Large Area Display, LAD)를 포함하며 고신뢰의 이더넷기반의 소켓통신이 사용하였다. 마지막으로 실험결과 제안된 방법은 모든 패킷이 20msec의 데드라인에 패킷 손실이 전혀 없이 전달됨으로써 실시간성과 신뢰성 요구사항을 만족시키는 것으로 판명되었다. It is require to design the next generation avionics system while considering applicability under open architecture where standerd communication module is used. In this situation, if the existing schemes cannot guarantee new requirement, new system development is demanded. In this paper, we present design, implementation, and testing procedure for message based middleware to support operational flight program on avionics. System architecture include mission computer (MC) and large area display (LAD) over standard socket communication based on reliable Ethernet. Finally, experimental results demonstrate that the proposed middleware can guarantee real-time with 20msec as well as reliability requirements with no lost packet.

On the subject to the Samsung Medical Center(SMC), through theoretical study of the concept and utility of landscape architecture in hospital, Authors want to suggest a betterment and there comes the reason of this research. As the result of analysis of documentary records and design concept of SMC, the role of hospital got broadened and used generally and inclusively. Therefore, the construction and design of space needs to be for cure of patients and demands of residents around one's area. For this, it has been revealed that the introduction of spaces for patients and common users left much to be desired.

Using a pinus koraiensis and pinus rigida which are normally being discarded in South Korea, the optimal condition of producing charcoals has been studied to develop activated carbons which can be recycled as a higher value-added product. A study on manufacture of activated carbons from a discarded timber consists of two processes, the production process of charcoals from a discarded timber by low temperature pyrolysis process and the production process of activated carbons from the charcoals by chemical activation reaction. This study deals with the production process of charcoals from a discarded timber by low temperature pyrolysis process. As a results of experiment, it was investigated that charcoals produced through drying at $150^{\circ}C$ for 6hr and pyrolysis process at $500^{\circ}C$ for 1hr had the highest values in physical properties such as iodine number and BET surface area. Furthermore, through observing SEM images, the maximum development of porosity had been founded in this condition. It was confirmed that values of physical properties on using a pinus koraiensis are superior to the ones when using a pinus rigida. When charcoals were produced from a pinus koraiensis in this condition, BET surface area was approx. $640m^2/g$. 국내에서 대표적으로 버려지는 폐벌목인 잣나무와 리기다소나무를 이용하여 고부가가치 제품으로 활용할 수 있는 활성탄 개발을 위해 목탄 제조의 최적조건을 측정하였다. 폐벌목 활성탄 제조에 관한 연구는 저온열분해 공정에 의한 폐벌목의 목탄 제조공정과 화학적 활성화반응을 이용한 목탄의 활성탄 제조공정으로 나누어지며 본 논문은 저온열분해에 의한 폐벌목의 목탄 제조공정을 다루고 있다. 실험결과, 목탄 제조공정의 경우 $150^{\circ}C$에서 6시간 건조 후 $500^{\circ}C$에서 60분 동안 열분해 공정을 거쳐 생성된 목탄이 요오드 흡착력과 비표면적(BET)등의 물성이 가장 우수하였으며 SEM사진을 관찰한 결과 이 조건에서 세공이 발달함을 알 수 있었다. 일반적으로 잣나무를 이용하여 제조된 목탄의 물성치가 리기다소나무를 이용한 목탄보다 우수함을 알 수 있었다. 본 연구의 최적 실험조건에서 잣나무를 이용한 목탄의 경우 BET값이 약 $640m^2/g$에 이르렀다.

In this paper, I assert that moral elements(德目) can be taught from child-hood as Aristoteles said. But on what gounds do I advocate that moral elements can be taught? It is because I believe that the meaning of moral elements is objectively real independent of human-beings and there is some characteristic which belongs to every moral element like G.E.Moore's view-point. Moreover I believe that the meaning of moral elements can be inquired, discovered and accomplished by human-beings alone. Then what is the best way to teach moral elements to children at the hour of moral education-department in the curriculum of our primary school? Above all I think that all teachers of the primary school should have the unified model of steps in the process of teaching and learning in moral education department. But many teachers have n model of steps in the process when they teach the children moral elements. Therefore in this paper I assert that all teachers should teach moral elements to children on the basis of a unified model of steps in the process and the model should be operated by Bruner's theory.
