네트워크 중심전에서 C4I체계의 안정적 운용을 통한 전장에서의 정보우위 달성을 위해 체계의 신뢰성 확보가 필요하여 각 군 C4I체계는 외주 용역업체를 통해 유지보수를 수행 중에 있다. 유지보수는 C4I체계의 수명 주기 중 가장 오랜 기간을 차지하고 있으며 결함 데이터 등의 실증적인 자료를 확보할 수 있는 기간이다. 따라서 유지보수 기간 중 수집한 결함 데이터를 결함분석기법을 통해 분석(치명도, 발생빈도)하고, 주요기능별 활용도를 이용하여 C4I체계 유지보수 관리 우선순위 선정기법을 제안한다. 이 후 제안 기법을 해군 C4I체계의 군적용 사례연구를 통해 유지보수 관리 우선순위를 선정함으로써 유지보수의 제한된 자원(예산, 인력, 시간 등)을 효율적으로 활용하기 위한 판단의 근거로 사용이 가능함을 보인다. 뿐만 아니라 체계화된 결함분석과정을 통해 축적된 자료를 활용하여 유지보수의 연속성 보장과 향후 성능개량사업간 시스템 분석의 참고자료로 활용함에 따라 궁극적으로 C4I체계의 신뢰성을 향상시킬 수 있다.

The summary of this paper is as follows. The literature on existing expert system maintenance software technique are reviewed in Module program, a case of assembly line process problem at construction industry and planning expert system to solve this problem at construction as a standard configured process system are discussed. the regenerative expert system approach for the construction process expert system and its example for the assembly line construction process appear in the research also, this paper shows the architecture and some feature of the CES.(Construction Expert System), which is a prototype implemented for the regenerative expert system approach. the paper introduce the framework of the regenerative expert approach as a general framework of developing and maintaining a large-scale expert systems.

This study presented the analytical evaluation model effective in the concrete structure repaired with a patching material. The model considered the effect of the repair material on carbon dioxide penetration into the repaired concrete as evaluating the remaining service life of the CO2-deteriorated concrete structure after repair. The diffusion profiles of carbon dioxide as well as the carbonated concrete were effectively able to be modelled with analytical method based on Fick's 1st diffusion law.

The purpose of this study is to present a plan to design and utilize effectively useful software program in dealing with Teaching Materials and Tools Management in all infant education institute. This program is called Teaching Materials and Tools Management and it is based on the national kindergarten Curriculum notified by ministry of education. To achieve this goal, all teaching materials should be kept to classify and use easily regardless of their shape, kind, and maker(manufacturer). Teaching materials and tools once used in class should be kept after being repaired, And if it is difficult to repair them, write down detail information about them for any teacher to repair them easily. Teaching materials and tools should classified efficiently after being used and registered to recognize their information at first glance. Teaching materials and tools should be registered with an index to manage curriculum effectively when establishing a year plan.

Confucius has been viewed as a conservative thinker. Quite a few scholars even argued that it was Confucius who laid the foundations stone of the conservative tradition of Chinese politics. No matter how one defines "conservatism," it seems clear that the relevant passages in the Analects support such interpretation. However, Lothar von Falkenhausen, an archeologist, recently argued that what Confucius upheld as venerable tradition was not a distant past but Confucius own times. This paper attempts to resolve the contradiction between the archeological evidence of Falkenhausen's claim and the textual evidence of the Analects through closer reading of the evidence.

본 논문에서는 신뢰성을 기반으로 하여 유지보수 비용과 리스크 양쪽을 고려해야 하는 장비의 최적한 유지보수를 정하는 방법을 나타내고 있다. 이러한 방법으로 장비의 고장 과정을 바탕으로 하는 확률론적 모델을 제시한다. 최적점검주기는 유지보수 비용과 고장으로부터 받은 피해비용의 총 비용을 최소화시킬 때 정해진다. 여기서는 신뢰성을 정량적으로 평가하기 위해 기기가 고장에 도달하는 경과를 나타내는 고장 모델을 작성하여 고장에 의해 발생하는 피해액을 산출하여 시스템 전체에서의 보전비용과 고장에 의한 피해액과의 총 코스트가 최소가 되는 보전주기를 최적한 보전주기로 한다.

This study aims to determine the perspectives of pre-service elementary school teachers on the science curriculum in the fourth industrial revolution era. In this study, 128 pre-service elementary school teachers were asked to express their perspectives on the Saber-toothed Tiger Curriculum through photovoice activities. The resulting images were classified into three types: conservative, progressive, and radical perspectives. The number of both conservative and progressive perspectives was similar and high, whereas the number of radical perspectives was l ow. Those who had conservative perspectives on the Saber-toothed Tiger curriculum regarded "Inquiry" as the basis of the science curriculum, which should be maintained regardless of the time period and environment. Similarly, older teachers believed that this curriculum was based on eternal truth, which should be protected. Those who showed progressive perspectives on the Saber-toothed Tiger curriculum regarded a progressive person as someone succeeding to the blood of "New fist," and they showed positive attitudes toward AI-based education such as coding and meta-verse, regarding these practices as part of the teaching and learning method that could replace the existing inquiry-based education. Those who showed radical perspectives on the Saber-toothed Tiger Curriculum assumed critical attitudes toward the rapidly changing political circumstances of science education and criticized conflicts between different social classes formed through progressive curriculum. Based on these results, this study found that pre-service elementary school teachers needed to consider the science curriculum from several different perspectives rather than just one.
