NiAl powders containing oxide dispersoids have been produced by mechanical alloying process in a controlled atmosphere using high energy attrition mill. The powders have been consolidated by hot extrusion and hot pressing followed by isothermal annealing to induce microstructure coarsening to improve high temperature properties. Grain growth and dispersoid coarsening kinetics have been investigated as functions of annealing time and temperature. Coarsening of dispersion strengthen NiAl and dispersoid has been discussed. Some clues of secondary recrystallization have been investigated. Mechanical property measurements have been also made and correlated with the microstructures.

전문가 시스템은 인공지능 분야에서 가장 성공적인 사례로 꼽히고 있다. 본 논문에서는 전문가 시스템에서 채용하고 있는 핵심기술인 패턴-액션 규칙이 자연어 구문 분석 작업에도 성공적으로 적용될 수 있음을 보이고자 한다. 자연어의 문법 규칙을 전문가 시스템의 생성 규칙 형태로 표현하고, 전문가 시스템의 추론 엔진에서 이용하는 알고리즘(특히 전향 추론 방식)을 이용하여 구문 분석을 진행하도록 한다. 이 방법이 부분 자유 어순과 중심어 후행과 같은 특징을 가진 한국어의 분석에도 적용될 수 있음을 보였다.

작업 기억내에서의 통사처리과정을 살펴보기 위해 생략어를 포함하는 네가지 유형의 대등 연결문을 마지작 단어 읽기 과제를 통해 비교하였다. 특히 통사과정에 관한 설명으로 제시되는, 근접 가설, 작업 기억 가설, 최근 필러 이용 가설의 상대적 설명의 효율성을 검증하고자 하였다. 실험 결과는, 주어가 공통논항인, 표준 어순의 연결문이 다른 세 유형의 연결문보다 이해 시간이 빨랐다. 이 결과는 어느 한 가설로는 설명될 수 없으며, 대안적인 설명으로 작업 기억내에서 이용 가능한 여러 정보의 상호 제약에 의해 이루어짐을 논의 했다.

There are various researches which proposed an automatic instance generation from freetext on the web. Existing researches that focused on English, adopts pattern representation which is generated by simple rules and regular expression. These simple patterns achieves high performance, but it is not suitable in Korean due to differences of characteristics between Korean and English. Thus, this paper proposes a novel method for generating patterns and instances which focuses on Korean. A proposed method generates high quality patterns by taking advantages of dependency relations in a target sentences. In addition, a proposed method overcome restrictions from high degree of freedom of word order in Korean by utilizing postposition and it identifies a subject and an object more reliably. In experiment results, a proposed method shows higher precision than baseline and it is implies that proposed approache is suitable for self-knowledge learning system.

The purpose of this paper is to investigate the phenomena of preposing and inversion in English from the discourse-pragmatic perspectives. We claim that different types of preposing can be unified to a single process of topicalization. We also show that diverse discourse functions of inversion can be subsumed under the ‘linking’ function with the prior discourse. It is followed a comparative discussion between preposing and inversion to find what similarities the two constructions share and what differences there exist between the two. It is concluded that the choice of a syntactic forms ultimately depends on the speaker's evaluation of the information status of the knowledge store of the hearer.
