본 논문은 Contour Crafting(CC) 프로세스의 압출과 적층 단계에서 물질 흐름의 형태를 연구하기 위한 실험과 모델링을 보여준다. 특히, 실험재료로써 진흙을 이용한 압출과 적층 메커니즘을 이해하기 위하여 기초적인 유한성분분석(FEA)을 실행하였다. FEA 시뮬레이션을 이용한, CC의 성능에 있어서 압출구멍의 기하학적인 효과에 대한 분명하고 기본적인 이해를 하게 되었다. 네모난 형상이 원하는 외부 표면특성을 만드는 것뿐만 아니라, 그리고 층간에 최적의 융합을 수행하는데 있어서 가장 적합하다는 것을 알아냈다. 우리의 실험은 이 결과들을 증명한다.

최근 각광 받고 있는 멀티 터치 인터랙션 시스템에서 기존의 디스플레이 방식인 벽면 디스플레이 방식의 네모난 형태의 디스플레이 방식이 아닌 볼록형(Convex) 불규칙 디스플레이 방식으로 산 모양의 디오라마 형태의 디스플레이에서 멀티 터치 인터랙션이 가능한 시스템을 제안한다. 먼저 볼록형 불규칙 표면의 산 디오라마를 제작을 하고 후면 투영 방식으로 프로젝터 영상을 산 디오라마 표면을 대상으로 디스플레이 하고 영상 분석 모듈을 통하여 터치 인터랙션 좌표 정보를 분석한다. 분석된 터치 인터랙션 좌표는 3D 좌표로 변환하고 디스플레이 모듈에 보내면 디스플레이 모듈에서는 인터랙션 메타포로 분석하고 결과를 콘텐츠에 실행시킴으로써 볼록형 불규칙 표면의 산 디오라마에서 멀티 터치 인터랙션에 따른 결과를 사용자가 체감 할 수 있도록 하였다. 본 시스템은 향후 다양한 디오라마 형태로 제작하여 목적에 맞는 전시 시스템으로의 디바이스나 체감형 아케이드 게임 디바이스로 활용이 가능할 것이다.

The integral image is the sum of input image pixel values. It is mainly used to speed up processing of a box filter operation, such as Haar-like features. However, large memory for integral image data can be an obstacle on an embedded hardware environment with limited memory resources. Therefore, an efficient method to store the integral image is necessary. In this paper, we propose a memory size reduction hardware design for integral image. The hardware design is used two methods. It is the new integral image memory and modulo calculation for reducing integral image data. The new integral image memory has additional calculation overhead, but it is not obstacle in hardware environment that parallel processing is possible. In the Xilinx Virtex5-LX330T targeted experimental result, integral image memory can be reduced by 50% on a $640{\times}480$ 8-bit gray-scale input image.

This survey was performed to investigate the actual holding conditions of the electric tools, gas tools and small cooking tools in the four Korean big cities; Seoul, Pusan, Kwangju and Taejon. The results were as follows; 1. Each family had more than 8 items on the average, of 24 kinds of electric tools under investigation. The holding ratio of refrigerators was the highest (99.6%), and that of dish washers was the lowest (3.4%). 2. The holding ratio of gas-ranges was the highest(92.2%) and that of gas-ovens was the lowest (2.2%) of 4 kinds of gas tools under investigation. 3. Each family had more than 45 items on the average, of 86 kinds of small cooking tools under investigation. The holdings ratios of openers and wicker baskets were very high (98.2% and 96.6%, respectively), and those of noodle tools and Shinsonros were very low (13.8% and 13.6%, respectively). 4. The holding ratios of various kinds of cooking tools had interrelations with the size of city, housewife's educational background, family income, house style, private residence, etc.

This survey was performed to investigate the holding amount of the various kinds of cooking tools of the farm and fishing villages in Chungnam area. The results were as follows: 1. The holding ratio of refrigerators was the highest (97.9%), and that of toasters was the lowest (1.9%) among the electric tools. 2. The holding ratio of gas-ranges was the highest (95.7%) and that of gas oven-ranges was the lowest (1.2%) among 4 kinds of gas tools under investigation. 3. The holding amount of pans was the highest among the cooking tools and that of wicker baskets was very high among the small cooking tools. The holding ratios of egg-cutters and lemon-squeezers were very low (4.1% and 2.9%, respectively). 4. The holding ratios of various kinds of cooking tools were related to the housewife's educational background and family income.
