본 논문에서는 영어 회화 교육을 위한 예제 기반 대화 시스템에 대해 논한다. 기존의 획일적인 멀티미디어 영어 학습에서 벗어나 자연어 처리 및 대화 기술을 이용하여 지능적인 일대일 영어 회화 교육 제공을 목적으로 한다. 본 시스템은 미숙한 학습자 발화를 이해할 수 있으므로 불완전한 언어 구사 능력으로도 대화를 참여할 수 있는 체험형 학습을 제공한다. 이를 통해 학습자에게 영어를 배우려는 흥미로운 동기를 부여한다. 또한 학습자의 표현력 향상을 위한 교육적인 도움 기능을 갖추고 있다. 이를 위해 우리는 학습자의 미숙한 표현을 이해하는 담화 상황 고려 발화의도 인식 모델, 도메인 확장성이 뛰어난 예제 기반 대화 관리 모델, 교육 및 평가 기능을 개발하였다. 실험 결과 학습자의 발화에 에러가 많아도 높은 발화의도 인식 성능을 보였으며 대화 상황에 적합한 피드백을 제공하여 학습자가 회화 연습을 끝까지 마치도록 도와 교육 효과에 이바지함을 알 수 있었다.

본 논문은 새로 개발된 파괴형태를 고려한 암반사면의 신뢰도해석 모델의 검증을 위하여 예제를 통한 민감도해석을 수행하였고 그 결과를 수록하였다. 민감도분석에 이용된 매개변수는 암반 불연속면의 공학적 특성 (불연속면의 방향 및 강도),하중조건 및 암반사면의 기하학적 형상 등이다. 확률론적 해석에서 고려할 수 있는 불연속면의 방향 및 마찰각의 통계적 특성이 파괴형태를 고려한 암반사면의 안정에 큰 영향을 보였다. 암반사면의 안정은 굴착면의 방향에 가장 민감하였다. 예제분석을 통하여 개발된 파괴형태를 고려한 암반사면의 신뢰도모델은 암반사면의 안정성 조사에 성공적으로 적용할 수 있었다.

오늘날 대부분의 조직들은 프로세스 중심의 업무 관리를 위해 노력하고 있고, 이를 위한 Business Process Management(BPM)의 개념은 점차 확산되어 가고 있는 추세이다. ISO 9001:2000 품질경영시스템이 Business Process Re-engineering(BPR)의 영향을 받았고, 프로세스 중심적인 경영시스템이기 때문에, BPM은 ISO 9001:2000 품질경영시스템과 다르지 않다고 본다. 한국과학기술정보연구원(KISTI)은 2003년 11월 11일에 ISO 9001:2000 인증은 받았고, BPM 기반의 품질정보시스템을 구축하였다. KISTI의 품질정보시스템은 BPM을 기반으로 하여 프로세스 경영을 잘 지원할 것이며, BPM과 품질경영을 접목한 새로운 사례가 될 것이다.

Development, availability and users' participation in the information service of agricultural food sector is slower than that of other sectors in Korea. This phenomenon comes from the lack of development strategies and comparative analyses with other sectors, as well as the agricultural food industry's own characteristics which is developed based on the offline market. In this research, we will discuss about how to improve the public information service of agricultural food sector based on the example of establishing service improvement strategy by the most representative Okdab. In this research, we have drawn the following implications for development strategy of Okdab service based on three core keywords derived from benchmarking KOSIS. Three core subjects for upgrading public information service are 'analysis information with expertise and differentiation,' 'user cooperation-oriented platform,' and 'intuitive nd effective UX,' and to strength B.I. as an integrated information service of agricultural food sector, we need to identify the users' satisfaction and needs for the existing service, establish an optimized operating strategy on a short-term, mid-term and long term bases, and implement them in a positive way. Based on this positive action, it can become a trustworthy information service for the users, and we can expect the improvement of the users' recognition for its consistent usability and efficiency.

Recently, an infinite class of finitely based finite involution semigroups with non-finitely based semigroup reducts have been found. In contrast, only one example of the opposite type-non-finitely based finite involution semigroups with finitely based semigroup reducts-has so far been published. In the present article, a sufficient condition is established under which an involution semigroup is non-finitely based. This result is then applied to exhibit several examples of the desired opposite type.

최근에 웹의 폭발적 사용의 증가에 따라, WWW에서 많은 정보를 좀 더 손쉽게 획득할 수 있다. 본 논문에서 H에서 웹 에이전트를 사용하여 이미지를 검색하는 일반적인 내용기반 이미지 검색 시스템을 제안한다. 웹 에이전트는 웹 상에서 HTML문서에 나타나는 텍스트 중 이미지 이름이나 링크에 붙어 있는 이미지를 의미하는 텍스트를 추출한다. 제안된 시스템은 웹 브라우저에서 사용자의 스케치와 예제 이미지 질의를 이용하여 데이터베이스에 있는 이미지를 검색하는 방법을 제시하여 실험결과를 통해서 질의 효율성을 나타내었다.

The objective of this paper is to present a methodology for automatically balancing multi-cavity injection molds with the aid of flow simulation. After the runner and cavity layout has been designed, the methodology adjusts runner and gate sizes iteratively based on the outputs of flow analysis. This methodology also ensures that the runner sizes in the final design are machinable. To illustrate this methodology, an example is used wherein a 3-cavity mold is modeled and filling of all the cavities at the same time is achieved. Based on the proposed methodology, a multicavity mold with identical cavities is balanced to minimize overall unfilled volume among various cavities at discrete time steps of the molding cycle. The example indicates that the described methodology can be used effectively to balance runner systems for multi-cavity molds.

A hybrid structural reliability analysis method that integrates a commercial finite element program and a reliability analysis algorithm is proposed to estimate the safety of real structures in this paper. Since finite element method (FEM) is most commonly and widely used in the analysis and design practice of real structures, it appears to be necessary to use general FEM program in the structural reliability analysis. In this case, simple conventional reliability methods cannot be used because the limit state function can only be expressed in an algorithmic form. The response surface method(RSM)-based reliability algorithm with the first-order reliability method (FORM) found to be ideal in this respect and is used in this paper. The intention of use of RSM is to develop, albeit approximately, an explicit expression of the limit state function for real structures. The applicability of the proposed method to real structures is examined with help of the example in consideration of a concrete dam. Both the strength and serviceability limit states are considered in this example.

GENIE is a learning-based engine for building intelligent systems. Learning in GENIE proceeds by incrementally modeling its human or technical environment using a neural network and a genetic algorithm. The neural network is used to represent the knowledge for solving a given task and has the ability to grow its structure. The genetic algorithm provides the neural network with training examples by actively exploring the example space of the problem. Integrated into the training examples by actively exploring the example space of the problem. Integrated into the GENIE system architecture, the genetic algorithm and the neural network build a virtually self-teaching autonomous learning system. This paper describes the structure of GENIE and its learning components. The performance is demonstrated on a robot learning problem. We also discuss the lessons learned from experiments with GENIE and point out further possibilities of effectively hybridizing genetic algorithms with neural networks and other softcomputing techniques.

Community action is an essential component for health promotion. Through effective community action, a community can gain control over its health & health determinants, and improve the quality of its life. The Ottawa Charter for Health Promotion (WHO, 1984)stated that a health promotion program that stimulates and strengthens community health activity is one of the five main action areas in the field of health promotion. This paper reviews the meaning and key concept of community health promotion action, and discusses ways to strengthen community action as defined by the Ottawa Charter for Health Promotion. It discusses the principle of community participation for health promotion, and, taking a successful example of a community-based health promotion program, it provides an illustrative example of how to build partnerships and coalitions in a community. Community development theories for community-based approaches are also introduced, along with their key concepts. Finally, the paper assesses the barriers to effective community health promotion action in Korea, and proposes several strategies for strengthening community action for health promotion.
