회로이론의 분야는 꾸준히 성장하여 왔고 System modeling과 system analysis가 새로운 분야로서 등장되어 IEEE에서도 1972. 9. 18. Circuits group를 circuits & Systems Society로 개칭하게 되었다. 회로이론과 그 기교는 비단 전기 및 전자공학에만 적용되는것이 아니라 대시스템분야, 생의학분야, 경제분야에도 공히 적용될 수 있다. 본고에서는 회로 및 시스템분야에 있었던 주요 연구경향을 1974 IEEE International Symposium on Circuits and System에 근거를 두고 미국중심으로 살펴보고 국내 전기 및 전자공학회지를 추적하여 최근의 국내 및 국외 연구동향에 대하여 알아보고자 한다.

This study analyzed that technological competition, variety and simility of Green IT fields using patents data. To achieve this, we limited range of Green IT that reduction of energy, eco-friendly technology. Therefore we conducted analysis of patents that power saving systems, light control system, smart system, cloud computing and green house/eco systems. As the result of that, power saving field was the most developed. The simililarty of power saving and cloud computing systems are very high and similiarities of light control system, green house/eco systems and smart system were very high.

사용자 프로파일(user profile)은 사용자 개개인의 관심 분야를 기술한 것이다. 정보 시스템이 사용자 개개인의 관심 분야를 알고 있다면, 사용자의 관심 분야에 속하는 문서만을 사용자에게 제시해 줌으로써 정보검색의 효율을 높일 수 있다. 사용자 프로파일 관리 시스템은 시간이 지날수록 개인 사용자의 관심분야를 더욱 잘 나타내어야 하고(Specialization), 사용자의 관심 분야가 변화해도 그에 대응해야 하며(Adaptation), 사용자가 흥미있어할 만한 관련 분야도 제시할 수 있어야 한다(Exploration). 본 논문은 기존에 연구되어 왔던 정보여과 시스템에서 사용되는 사용자 프로파일 관리 시스템들의 단점을 보완하고 정보검색 시스템에서도 사용될 수 있는 범용성을 지닌 사용자 프로파일 관리 시스템을 제안한다. 제안하는 사용자 프로파일 관리 시스템은 사용자의 관심분야의 변화를 유전자 알고리즘을 이용하여 모델링하고, 여러 유전자군(群)으로 사용자의 다양한 관심분야를 기술한다.

This study is intended to present methods improving the classification system of KDC architecture engineering fields after comparing and analyzing the academic system of architecture engineering, classification system of KDC, DDC, and LCC, and that of the research field classification system of National Research Foundation of Korea. The results of the analysis have revealed that it is required to improve and correct the KDC 5th edition of architectural engineering including the addition of classification items that reflect the trend of academic development, proper development in the rank classification terms of architectural structure engineering, addition of detailed subjects, selection of proper classification terms, errors of classification symbols and English expression, and omission of correlative indexes in the classification items. This study has proposed improved methods to solve those problems.

인공지능(Artificial Intelligence : AI)이란 인간이 가지고 있는 지각, 인식, 이해, 기억, 판단, 학습, 사고, 발견, 창조 등과 같은 지적인 능력을 기계에 실현하고자 하는 분야이다. 즉 기계에 인간이 가진 지능을 복제하여 우리 인간이 소유하고 있는 추론과 학습 메커니즘 등을 이용하여 신속한 계산을 수행할 수 있도록 컴퓨터의 실제 능력을 향상시키는 것이다. 인공지능 분야는 다양한 분야에 응용되어 왔으며 수많은 기술들이 개발되었다. 석유 분야도 예외는 아니며 석유 지질, 탐사, 매장량 평가, 시추, 생산, 수송, 정제 등 다양한 분야에 걸쳐서 인공지능 분야가 활용되어 많은 문제 해결에 적용되고 있다. 이와 같은 취지에서 본 논문에서는 우선 석유 분야별로 활용되고 있는 인공 지능 분야들을 정리하고 그 후 인공지능 분야별로 실제 해결하고 있는 석유 분야의 문제들을 다시 한번 정리하였다. 그 후 특히 석유 분야가 있어서 실제 개발되어 사용중인 전문가 시스템들을 정리하였다. 마지막으로 향후 석유 분야의 전문가 시스템 발전 방향을 간략히 분석하였다.

As it was developed to korea standard of the CAD Drawing in Construction CALS/EC for the productivity Improvement in Construction Industry and efficiency rising of construction management. it is high time to design the standard system in water resources. The purpose of this study is to establish the strategies for standard system of drawing information in water Resources parts for construction CALS/EC. This study is to analyse the existing construction drawing standards including CMS, CMMS, drawing guideline of a water Resources public institution, ISO, US National CAD Standard, Japanese Standard. As a result of the analysis, this study proposes the prime structure of the water Resources drawing information standard to support construction CALS/EC. For the establishment of standard system in real practice, this study establishes the numbering system to joint the current standard system for a water Resources order institution and to keep construction CALS/EC. In conclusion, the standard system of drawing information is proposed as a fundamental frame to water Resources parts of construction CALS/EC.
