An architecture is a result from representation of design knowledge by architect's creative thinking, and operated only in his internal organization system. Design knowledge based upon the experience that they have achieved in the past as well as the informations they have accumulated over the time. In this point of view, the Schema that formed by problems settlement and process repetitions for the best conclusion, not only play an important part in the designer's thinking system about a specific problem but also appeared by distinctive features. This research looks to achieve a new design method by finding out how architects express traditionality in the contemporary house through schema. This research analyze contemporary house built in seoul of 1990's. The result are as followings. First, Schema is a 'frame' that already exist in the architect's thinking, will make a good guide about express the traditionality. Second, We found out several distinctive characters in the form and the space. The form is divided in five types. It is an condensed form of roof image, the metamorphosis of form grammar, the change of part details, the representation of design principle and the directly expression. Lastly, In the space, it is the borrow of the connection method of inside and external space, the three parts composition of the space, the adaptation of 'Madang' and the Independent composition of the space due to 'Chae'

Configuration is a set of building block processes, a series of selection and combining parts or components which composes a whole thing. A whole thing could be such a configurable object as manufacturing product, network system, financial portfolio, system development plan, project team, etc. Configuration problem could happen during any phase of product life cycle: design, production, sales, installation, and maintenance. Configuration has long been one of cost and time consuming work, because only high salaried technical experts on product and components can do configuration. Rework for error adjustments of configurations at later process causes far much cost and time, so accurate configuration is required. Under the on-line electronic commerce environment, configuration problem solving becomes more important, because component-based sales should be done automatically on the merchant web site. Automated product search, order placement, order fulfillment and payment make that manual configuration is no longer feasible. Automated configuration means that all the constraints among components should be checked and confirmed by configuration engine automatically. In addition, technical constraints and customer preferences like price range and a specific function required should be considered. This paper gives an brief overview of configuration problems: characteristics, representation paradigms, and solving algorithms and introduce CRSP(Constraint and Rule Satisfaction Problem) method. CRSP method adopts both constraint and rule for configuration domain knowledge representation. A survey and analysis on web sites adopting configuration functions are provided. Future directions of configuration for EC is discussed in the three aspects: methodology itself, companies adopting configuration function, and electronic commerce industry.

Knowledge discovery refers to the overall process of discovering useful knowledge from data. The linear programming model is a special form of useful knowledge that is embedded in a database. Since formulating models from scratch requires knowledge-intensive efforts, knowledge-based formulation support systems have been proposed in the DSS area. However, they rely on the strict assumption that sufficient domain knowledge should already be captured as a specific knowledge representation form. Hence, the purpose of this paper is to propose a methodology that finds useful knowledge on building linear programming models from a database. The methodology consists of two parts. The first part is to find s first-cut model based on a data dictionary. To do so, we applied the GPS algorithm. The second part is to discover a second-cut model by applying neural network technique. An illustrative example is described to show the feasibility of the proposed methodology.

This paper explores the applications of feature-based representation and design in the area of design for manufacturing to incorporate the tooling and process considerations into the early stages of bonnet tool design. The goal of this research is apply the concepts of feature-based design and to development an interactive design tool using relations and arrive at optimal design for the given process conditions. This paper illustrates the development of a tool design aided system that was constructed using these concepts and applied to designing bonnet sheet metal parts.

As a product structure or BOM(bill of material) of products is hierarchically structured, the design based on the concept of relational data base modeling causes low performances in data search or processing. For this reason, an object-oriented approach to designing a product structure is proposed in this paper. Using Rumbaugh's OMT (Object Modeling Technique) method, classes of parts, BOM structure, options, and models are defined and their class-relationship diagrams are proposed. For the representation of the BOM structure suitable for the object-oriented paradigm, a new data architecture called the BOM item class is suggested. It is expected that the proposed data structure ensures better reusability and expandability due to the modularity.

미디어 영상, 예술 분야에서의 표현 특징들 중 초현실주의의 표현 기법을 이용한 많은 작품이 출시되고 있으며 이에 대한 연구가 시작 진행되고 있다. 그러나 아직 게임 캐릭터의 표현 특징 중 초현실주의의 표현 특징에 관한 연구는 거의 전무한 상태이다. 따라서 본 논문에서는 초현실주의에서의 표현 기법을 중심으로 판타지 게임 캐릭터의 표현 특징을 분석하였다. 그 결과, 초현실주의에서는 신체의 일부와 동물 또는 다른 사물을 꼴라쥬 하는 형태와 변형, 그리고 왜곡을 이용하여 현실에 존재하지 않는 이미지들을 표현하였는데 이러한 방법들은 판타지를 기반으로 한 온라인 게임 캐릭터에서도 유사하게 사용되었다. 본 논문은 미학적 맥락 속에서 판타지 게임 캐릭터들의 특징을 분석하여 현 시대 문화적 배경 속에 게이머들의 심리를 이해하여 보다 호감 있고 창조적인 게임 캐릭터 제작에 도움을 주며, 예술 기법 활용의 가능성을 증가시켜 창의적인 게임 그래픽 제작의 가능성을 여는데 의미가 있다.

This paper deals with an automated forming sequence design system by which designers can determine desirable operation sequences even if they have little experience in the design of cold forging process. The forming sequence design in the cold forging is very important and requires many kinds of technical and empirical knowledge. They system isproposed, which generates forming sequence plans for the multistage cold forging of axisymmtrical solid products. Since the process of metal forming can be considered as a transformation of geometry, treatment of the geometry of the product is a key in planning process. To recognize the geometry of the product section, section entity representation and primitive geometries were used. Section entity representation can be used for the calculation of maximum diameter, maximum height, and volume. Forming sequence for the part can be determined by means of primitive geometries such as cylinder, cone, convex, and concave. By utilizing this geometrical characteristics (diameter, height, and radius), the product geometry is expressed by a list of the priitive geometries. Accordingly the forming sequence design is formulated as the search problem which starts with a billet geometry and finishes with a given product one. Using the developed system, the sequence drawing with all dimensions, which includes the proper sequence of operations for the part, is generated under the environment of AutoCAD. Based on the results of forming sequence, process variables(strain, punch pressure, die inner pressure, and forming load) are determined.

It is a story-based content creation service that provides any user with some proper contents based on a story written by the user in order to utilize a lot of contents accumulated on Internet. For this service, the story has to be described in computer-readable representation. In this paper, analyzing the structure of scenario, as known as screenplay or scripts, a structure of story representation, which is referred to as OpenScenario, is defined. We intend users to produce their own contents by using massive contents on Internet by the proposed method. The proposed method's OpenScenario consists two main parts, OSD (OpenScenario Descriptors) which is a set of descriptors to describe various objects of shots such as visual, aural and textual objects and OSS (OpenScenario Scripts) which is a set of scripts to add some effects such as image, caption, transition between shots, and background music. As an usecase of proposed method, we describe how to create new content using OpenScenario and discuss some required technologies to apply the proposed method effectively.
