정보화 사회에 접어 들면서 정보를 판별하는 능력이 중요시 되고 있다. 그러나 정보가 점점 이질적이고 방대해 짐에 따라 사용자의 의도와 목적에 맞는 정보를 빠르고 정확하게 찾아내는 것이 어렵다. 정보검색 서비스를 제공하는 국내외 포털 사이트에서는 랭크 알고리즘을 이용하여 사용자에게 정보를 제공한다. 그러나 사용자의 요구를 충족시키기 위해 랭킹보다 더 중요한 것 정보를 압축시켜 사용자에게 사용자가 원하는 정보만 제공하는 것이다. 따라서 본 논문에서는 도메인을 제한하여 특화된 정보를 제공하며 사용자 위주의 더 특화된 정보를 제공하는 친구추가 기능을 제안한다. 동시에 주 검색 기능으로 사용자가 등록한 태그 링크를 따라 클릭하면서 연속적으로 정보 검색을 할 수 있는 연속정보검색을 제안한다. 그리고 제안한 시스템을 실제 웹 사이트를 구현을 통해 나타낸다. 제안한 시스템은 사용자에게 효율적으로 유용한 정보를 제공하는 기대효과가 있다.

This paper deals with automated computer-aided process planning by which designers can determine operation sequences even if they have little experience in the design of press working products. The computer-aided process planning in hot forging, deep drawing and blanking requires many kinds of technical and empirical skills based on investigation and collection of the knowledge of their processes. An approach to the CAPP system is based on the knowledge-based rules and the process knowledge base consisting of process planning rules is built. The methodology adopted to develop the system is elaborated in this paper. This system has been written in AutoLISP on the AutoCAD with a personal computer and provides powerful capabilities for process planning of hot forging, cold forging, deep drawing and blanking products.

인간은 태어날 때부터 접하게 되는 모든 것이 색으로 이루어져 있으며, 색상은 인간의 건강과 정신적 측면에 많은 영향을 끼친다. 어린 시절부터 색상 학습을 통해 색 자극을 지속적으로 주게 되면, 정서적인 안정감뿐만 아니라 감성 발달까지 유도할 수 있다. 본 논문에서는 안드로이드 운영체제 기반의 유아의 색 학습을 위한 안드로이드용 풍선 터뜨리기 게임을 구현하였다. 로그인 시스템을 적용하여 사용자 개개인의 학습 결과를 제공하고, 통합적인 데이터베이스를 구축하여 사용자의 랭킹 시스템을 구현하였다, 직관적인 조작이 가능하도록 UI를 적용하여 유아에게도 쉽게 색상 공부를 하도록 하였다. 추후 다양한 색들을 추가하여 다른 색도 학습할 수 있도록 개선하고, 개수와 속도조절을 통한 난이도 조절기능이 추가된다면 유아의 색의 학습뿐만 아니라 두뇌발달에도 도움이 되고 나아가서 손가락 재활이나 치매예방 등 다양한 분야에 적용될 수 있을 것으로 예상된다.

본 논문에서는 감성 기반으로 텍스타일을 자동으로 색인하고 검색 할 수 있는 시스템을 제안한다. 제안된 시스템은 영상 수집기, 감성 색인기, 검색기(Matcher), 질의 인터페이스로 구성되어 있다. 감성 색인기는 텍스타일 영상에 포함된 컬러와 패턴 정보를 기반으로 감성개념을 인식하고, 이를 이용하여 영상을 색인한다. 이때, 감성 어휘로 고바야시가 정의한 8개 (romantic, natural, casual, elegant, chic, classic, dandy, modern)를 사용한다. 질의 인터페이스에서 사용자는 두 가지 방식으로 질의를 선택할 수 있다. 첫 번째 방법은 감성 키워드를 사용하는 것이고, 두 번째는 사용자의 의도를 설명할 수 있는 영상을 이용하는 예제 기반 질의 방식이다. 질의가 주어지면, 검색기는 랭킹 알고리즘을 사용하여 검색 결과를 생성한다. 이 때, 유사도 비교방식은 선택된 질의방식에 따라 달라진다. 제안된 시스템의 성능을 검증하기 위해 웹 검색에 익숙한 50명(남자: 32명, 여자: 18명)을 대상으로 웹에서 수집한 3,416 장에 대해서 3가지 항목으로 사용자 평가를 하였다. 사용자 평가의 항목인 적합도(Relevance), 노력(Search Effort), 만족도(Satisfaction)의 결과로 사용자가 검색한 결과영상에서 적합도의 수치가 낮게 나왔지만, 만족도와 노력의 수치는 높게 평가되었다. 제안된 시스템에서 사용자는 자신이 선호하는 결과 영상을 상위 40개의 영상 내에서 얻을 수 있었다. 이는 제안된 시스템이 사용자들이 원하는 영상을 효율적으로 검색할 수 있다는 것을 증명했다.

In the new generation of Web, commonly called "Web 2.0", blogging has facilitated the publishing information or his/her opinion on the web. Various blog retrieval algorithms have been proposed to search for blogs more effectively. However, actually keyword-based searching or link-analysis blog ranking system cannot satisfy the user's requirement. In this paper, we suggest a topic-based weighting blog retrieval system in which the links between blog writings and searching words are considered to improve the search results. Our system extracts topics from each blog and weights them much higher than other guide words. In the comparison with other systems, we see that the proposed topic-base system has better recall rate of search results.

In future complex and diverse battlefield situations, the existing command system faces the challenge of delayed human judgement of strategy and low objectivity. This paper proposes an artificial intelligence model that takes situation information and course of action simulation results as input and automatically assigns scores to various evaluation elements and a comprehensive score. This tool is expected to assist the commander in making decisions, reduce the time required for making judgments, and promote impartial decision-making.

As the interests in health grow higher, necessity of Well-being relation informations get more importance. We get the information of well-being, tinternet retrieval system or blog, homepage and media. Although, it is not easy to find informations of well-being food. So, retrieval system has been requiring information about well-being food. In this paper, Weight-based Wellbeing Food Retrieval System is designed and implemention. Finding numerous pages and if well-being keywords includes page, it was identified and add weight. User searching for keywords, it implement, well-being food pages comes at the first. Keywords for discrimination makes type of dictionary, so it can insert, delete, modify. Inverted files saves hasing(direct-based file). Retrieval System in this paper is experimental result, at keywords of well-being food show 5~15% imprement than another Retrieval System. In this paper, Weight-based Wellbeing Food Retrieval System's designed and proposed way to raking for well-being food.

This paper describes a research work of developing a computer-aided design of blanking and piercing for irregular-shaped sheet metal products. An approach to the development of compact and practical CAB system is based on the knowledge-based rules. Knowledge for the CAD system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD with a personal computer. Based on knowledge-based rules, the system, STRT-DES, is designed by considering several factors, such as complexities of blank geometry and punch profile, availability of press equipment and standard parts, utilization ratio which minimizes the scrap in a single or a pairwise operation, bridge width, grain orientation and design requirements which maximize the strength of the part when subsequent bending is involved. This system checks a forming feasibility with both internal and external features, a dimension of blanked hole, and a corner and a fillet radius for irregualrly shaped sheet metal products. Therefore this system can carry out a die design for each process which is obtained from results of an automated blank layout drawing with a best utilization ratio for irregular shape of product that was successful in production feasibility check module and those of an automated strip layout drawing and generate part drawings and the assembly drawing of die set in graphic forms.

This paper describes a research work of developing a computer-aided design of blanking and piercing for irregular-shaped sheet metal products. An approach to the CAD system is based on the knowledge-based rules. Knowledge for the CAD system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD with a personal computer and is composed of four main modules, which are input and shape treatment, flat pattern layout, production feasibility check, and strip layout module. Based on knowledge-based rules, the system is designed by considering several factors, such as radius and angle of bend. material and thickness of product, complexities of blank geometry and punch profile, and availability of press. This system is capable of unfolding a formed sheet metal part to give flat pattern and automatically account for the adjustment of bend allowances to match tooling requirements by checking the dimensions and relationships of parts of the folded product. Also this system can carry out a process planning which is obtained from results of irregular shape of product that was successful in production feasibility check module according to flat pattern layout and generate strip layout drawing in graphic forms. The developed system provides its efficiency for flat pattern layout, and strip layout for the irregularly shaped sheet metal products.
