고대부터 문양은 그 민족과 국가의 생활에 깊이 내재해왔으며 특히 풍토, 지형, 종교, 사상, 사회구조와 같은 복잡한 요인들에 의해 성립되었다 그러므로 문양의 조형적 특질은 문양 그 자체에 한정되지 않고 조형전반의 문제로 파급되어 나타난다. (중략)

Vibration table is required to obtain high packing density in expendable pattern casting process. Packing density, which is an important manufacture factor, depends on the vibration pattern induced by vibration table. In general, circular vibration pattern is recognized as the best pattern. The existing vibration table is investigated to identify current vibration pattern and consider a countermeasure. Modal test is utilized to identify the dynamic characteristics of vibration table, and finite element method is used to present the improved design.

This paper discusses a new method of recognizing patterns employing consistent labeling. A consistent labeling problem is a generalized expression of constraint satisfaction problems. When a pattern is recognized by pattern matching, the matching between a reference pattern and an acquired pattern resolves itself into finding correspondence between the pixels on the former and those on the latter. This can be expressed as a consistent labeling problem. Pattern association, a variation of pattern recognition, is also described employing consistent labeling. The proposed technique is supported by experimental results, yet further studies need to be done before its practical use.

The tire is considered as one of the Important noise sources having an influence on vehicle's performance. The Pattern noise of a tire is the transmission sound of airborne noise. On smooth asphalt road, Pattern noise is amplified with the velocity. In recent, the study on the reduction of Pattern noise is energetically processed. Pattern noise is strongly related with pitch sequence. To reduce the pattern noise, tire's designer has to randomize the sequence of pitch. The FFT is a traditional method to evaluate the level of the randomization of the pitch sequence, but gives no information on time-varying, instantaneous frequency. In the study, we found that Time-Frequency transform is a useful method to non-stationary signal such as tire noise.

Membrane structures, a kind of lightweight soft structural system, are used for spatial structures. The design procedure of membrane structures are needed to do shape finding, stress-deformation analysis and cutting pattern generation, because the material property has strong axial stiffness, but little bending stiffness. The problem of cutting pattern is highly varied in their size, curvature and material stiffness. So, the approximation inherent in cutting pattern generation methods is quite different. Therefore the ordinary computer software of structural analysis & design is not suitable for membrane structures. In this study, we develop the program for cutting pattern generation using geodesic line, and investigate the result of example's cutting pattern in detail.

It was expressed repeated information on reuse design pattern in the design information because it was impossible to build a standardized design pattern in the existing design pattern tools. Also, It must possible to extend standardized design pattern just as one intended of designer. And It is able to express objects just as one intended of designer. Therefore, the representative characteristic of this paper was able to define XMI metamodel to express design pattern, and was able to extend metamodel to express design pattern.

This paper describes the ECG pattern recognition using the syntatic pattern recognition algorithm. The algorithm uses the BNF rule wi th the semantic evaluation which has the structural Information of the ECG. This algorithm is constructed with (1) removing the baseline drift by the Cubic spline function and exract the significant point by the line-approximation algorithm, (2) syntatic peak recognition algorithm with the extracted significant point, (3) produce the token which is used pattern recognition, (4) pattern recognition of the ECG by the syntatic pattern recognition algorithm, (5) extract the parameter with the pattern recognized ECG signal.

This paper presents a lip print recognition by the pattern kernels for a personal identification. A lip print recognition is developed less than the other physical attributes of a fingerprint, a voice pattern, a retinal blood/vessel pattern, or a facial recognition. A new method is proposed to recognize a lip print bi the pattern kernels. The pattern kernels are a function consisted of some local lip print pattern masks. This function converts the information on a lip print into the digital data. The recognition in the multi-resolution system is more reliable than recognition in the single-resolution system. The results show that the proposed algorithm by the multi-resolution architecture can be efficiently realized.

본 연구는 시트 커버지로 선호하는 직물의 특성을 파악하고자 하였다. 직물디자인의 평가 요소 중 pattern에 초점을 맞추었으며 부수적으로 색상에 대한 선호도 평가를 수행하였다. 직물 pattern 디자인은 PP(Primitive pattern)와 RPU(Repeated pattern unit)의 세부항목에 대한 평가를 통해 전체 직물패턴에 대한 평가가 가능하다. Pattern 특징 평가를 위한 1차 설문에서 소재와 색상의 요인들의 영향을 최소화하기 위해 sample 직물을 gray-scale image로 제시하여 세부항목을 평가하였다. 1차 설문결과로써 pattern 특성을 대표하는 4개의 직물샘플을 선정하였다. 2차 설문에서 4개의 대표 sample을 열차용 시트에 rendering 하여 선호도 평가를 수행하였으며, 색상 선호도 평가는 5가지 색상 군집에 대한 선호를 평가하였다. 선호도 평가 결과 시트 커버지로 선호하는 직물의 특징은 PP의 특징에 상관없이 RPU의 돌출성이 적은 pattern이었다 또한 색상은 초록색과 파랑색을 선호하는 것을 알 수 있었다. 추후 이러한 결과를 통한 시트 커버 직물의 디자인 및 선택이 이루어져야 할 것이다.
