Classification and Coding(C&C) systems as a core of design information management have been accomplished by many studies in terms of design and manufacturing attribute based on Group Technology. Those are very difficult to apply in make-to-order(MTO) manufacturing because the environment of MTO has various characteristics of product, many licensors, engineering change, insufficiency of integrated management system for codes and so on. This paper presents a suitable C&C system to MTO manufacturing which consider management level and drawing.

본 논문에서는 max-min 필터를 적용하는 방식의 도면 영상 열화와 강화에 따른 도면영상의 효과적인 전처리 방안과 벡터의 추출 및 건축 도면에서 나타나는 주벽의 특징에 기초한 주벽으로 결정하는 방안을 제시한다. 또한 영상의 획득시 발생할 수 있는 약간의 기울어짐(skew)에 영향받지 않는 벡터의 추출 및 병합방법을 통해 치수선과 치수선 끝점을 추출하고 인식하는 방법을 제시하고 있다.

'생물정보학'이란 생물학적 데이터를 처리, 가공하여 정보를 얻어내는 연구 분야로 이 중 대사체학은 대사 경로 네트워크를 가시화하여 생명 활동을 이해하고자 하는 분야로, 대사 경로 내의 흐름을 한 눈에 알 수 있도록 가시화하여 보여 주는 도구가 반드시 필요하다 따라서 본 논문에서는 새로운 '대사 경로 드로잉 알고리즘'을 제안하였다. 대사 경로 그래프의 구조로는 이분 그래프를 이용하여 가독성을 높였으며. 이 그래프가 척도 없는(scale-free) 네트워크 구조라는 것과 구조적으로 환형, 계층적 선형 컴포넌트를 가진다는 것을 고려하여 사이즈가 큰 그래프도 적절하게 드로잉 하도록 하였다.

An integrated process planning system can determine desirable operation sequences even if they have little experience in the design of multistage cold forging process. This system is composed of seven major modules such as input module, pre-design module, formability check module, forming sequence design module, forming analysis module, FEM verification module, and output module which are used independently or in all. The 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 part geometry is expressed by a list of the primitive 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 dimensional tolerances and the proper sequence of operations for parts, is generated under the environment of AutoCAD. Several forming sequences generated by the planning system can be checked by the forming analysis module. The acceptable forming sequences can be verified further, using FE simulation.

The characteristics of metabolic pathways make them particularly amenable to layered graph drawing methods. This paper presents a visual Java-based tool for drawing and annotating biological pathways in two- and a-half dimensions (2.5D) as an alternative to three-dimensional (3D) visualizations. Such visualization allows user to display different groups of clustered nodes, in different parallel planes, and to see a detailed view of a group of objects in focus and its place in the context of the whole system. This tool is an extended version of J2dPathway.

The purpose of this study was to analyze the writing styles and features of science writing by using science notebook for elementary school science gifted. The subject of this study was 37 sixth grade elementary school science gifted in P city. The preliminary 1 hour instruction was conducted to explain the usage of science notebook. The summarized activity using science notebook was conducted for 20 minutes following 4 hour lesson. These activities were performed for 8 times. As the result of this study, in The content which is learned today (main learning content)' which is one of components of science note, the writing appears the most frequently in external expression types and features of scientific writing, followed by writing+drawing, drawing, cartoon, writing+cartoon, mind map, table. Science writing which uses inductive thinking appears the most frequently in internal expression types and features of scientific writing, followed by deductive thinking, creative thinking. Among the components of science note, 'thinking and feeling', 'question,' 'one's own thinking of question' which are the components of science note promote the reflective thinking of elementary school student gifted for science.

The purpose of this study is to understand what Le Corbuiser has intended on a panoramic landscape view through his modern architectural design. This paper is willing to improve that he considered both natural and local landscape scenery, when he designed architecture with drawing images. He designed various ways to see outside scenery and community culture through ribbon windows, piloti, architectural promenade, picture frame, and rooftop garden as the angle of view inside the building, 'designed landscape panorama' from his architecture. Therefore the contents of the study include the analysis of the local landscapes shown through his architecture by photograph, drawing of a real scenery, and his sketches with biology to find what he has intended. The following conclusions have three points. First, Le Corbuiser has a basic idea to bear a natural and local scenery from his architecture through five points of new architecture. Second, pilotis, ribbon windows, and roof garden with picture frame and architectural promenade are pathways of his architecture to see 'designed landscape panorama'. Third, it comes from his early architecture like Villa Savoye in 1920s to Couvent de Sainte Marie de la Tourette in 1950s, but Ronchamp church converts his idea on previous thoughts.

In this paper, we describe the fabrication process and the characteristics of polarization maintaining photonic crystal fibers (PM-PCFs). The PM-PCF is fabricated by stack-and-draw method, i.e., stacking silica capillary tubes (making a PM-PCF preform) and drawing to optical fiber. Firstly, a PM-PCF preform is formed by stacking two kinds of capillary tubes around a solid silica rod and jacketing these stacked tubes with an outer silica tube (out-jacket tube). Later, the desired preform is drawn to a fiber in a high temperature drawing tower. We also compare the polarization properties such as polarization dependent loss, birefringence, and differential group delay of the fabricated PM-PCF with those of the conventional PANDA PM fiber.
