The purpose of this study was to research the design methods to express jacquard design using CAD. For this study, two design patterns were divided; in addition, each design pattern is applied to two different weaving types, single woven fabric and double well cloths. As a result, 16 samples were produced by applying 4 design methods (warp shrunk as half size design/weft shrunk as half size design - A, warp shrunk as half size design/weft original size design - B, warp original size design/weft shrunk as half size design - C, warp original size design/weft original size design - D) to the two design patterns with the two weaving types. The result of this study can be summarized as follows. 1. The most delicate design method was Method D. However, Method B which took half the time less than Method D was almost as delicate as the Method D on the surface. 2. Method B was judged as a considerably efficient method for time and cost. 3. Method D was considered as most suitable for elaborate parts and delicate lines. However, it was considered uneconomical since it took the longest time. 4. Mettled A took 2.5 times less time than Method D. Therefore, Method A was more applicable to producing high density design. 5. Method C is not considered as a useful method as it showed rough surface and took long time by applying high design zoom except intentional design.

The reuse of waste concrete amy settle the problems of environmental pollution and critical shortage of good natural aggregate. But recycled aggregate particles consist of substantial amount of relatively soft cement paste component. These aggregates are more porous, and les resistant to mechanical actions than natural aggregate. And the source of supply for manufacturing recycled aggregate is generally composed of different types of original aggregate and strengths of original mortar. The properties of recycled aggregate exhibit a considerable variation due to the properties of original concrete. This paper is an experimental study on the fundamental properties of recycled aggregates sampled from processing plant in the suburbs of TaeJeon.

Image stacking technique is one of the key techniques for complex surface reconstruction. The process includes sample collection, image processing, algorithm editing, surface reconstruction, and finally reaching reliable conclusions. Since this experiment is based on laser scanning confocal microscope to collect the original contour information of the sample, it is necessary to briefly introduce the relevant principle and operation method of laser scanning confocal microscope. After that, the original image is collected and processed, and the data is expanded by interpolation method. Meanwhile, several methods of surface reconstruction are listed. After comparing the advantages and disadvantages of each method, one-dimensional interpolation and volume rendering are finally used to reconstruct the 3D model. The experimental results show that the final 3d surface modeling is more consistent with the appearance information of the original samples. At the same time, the algorithm is simple and easy to understand, strong operability, and can meet the requirements of surface reconstruction of different types of samples.

The aim of this study is to evaluate the Pi-SAR data for land cover discrimination using a standard method. For this purpose, the original polarization and Pauli components of the Pi-SAR X-band and L-band data are used and the results are compared. As a method for the land cover discrimination, the traditional method of statistical maximum likelihood decision rule is selected. To increase the accuracy of the classification result, different spatial thresholds based on local knowledge are determined and used for the actual classification process. Moreover, to reduce the speckle noise and increase the spatial homogeneity of different classes of objects, a speckle suppression filter is applied to the original Pi-SAR data before applying the classification decision rule. Overall, the research indicated that the original Pi-SAR polarization components can be successfully used for separation of different land cover types without taking taking special polarization transformations.

This study was administered to identify features of masstiege high-end products by comparing to original old high-end products. For this purpose, the differences in shopping orientation between each consumer groups by product types(high-end products, original old high-end products) preferred were examined. 300 female consumers were surveyed and 279 data were used for analysis. The results are as follows. First, three elements(efficiency, enjoyment, convenience) of shopping orientation were constructed by factor analysis and efficiency element of all elements had highest explanation power. The differences in shopping orientation between masstiege high-end products and original old high-end products were identified by t-test. The consumers preferring original old high-end products regarded convenience element as an important factor and the consumers preferring masstiege high-end products considered efficiency element more. The correlation analysis between shopping orientation factors and demographic characteristics were administered. The consumers who were of low age, low education, low income and unmarried pursued efficiency more, the consumers who were unmarried, of high education and high income showed to pursue enjoyment more, and the consumers who were of high age, high education, high income and married considered convenience element more. Finally marketing strategies for masstiege brands were suggested.

공간 조인이란 서로 겹치는 관계를 가지는 공간 객체의 쌍들을 찾는 질의이다. 색인 기반 공간 조인에는 원공간 색인인 R 트리가 널리 사용된다. 원공간 색인이란 원공간상에서 표현된 공간 객체를 색인하는 구조로, 이를 활용한 조인은 크기를 가지는 공간 객체를 다루기 때문에 정형적인 방법이 아닌 휴리스틱에 의존하는 단점을 가진다. 반면, 변환공간 색인은 원공간 상의 공간 객체를 변환공간 상의 크기가 없는 점 객체로 변환하여 색인한 후에 이들을 다루기 때문에, 이를 활용한 공간 조인은 상대적으로 단순하고 정형적인 방법을 사용하는 장점을 가진다. 그러나, 이 방법은 R 트리와 같이 원공간 객체를 색인하는 원공간 색인에는 적용될 수 없는 문제점을 가진다. 본 논문에서는 이 두 방법의 장점만을 취하는 새로운 방법을 제안한다. 즉, 변환공간 뷰(transform-space view)라는 새로운 개념과 이를 사용한 공간 조인 알고리즘인 변환공간 뷰 조인 알고리즘(transform-space view join algorithm)을 제안한다. 변환공간 뷰란 원공간 색인에 대한 가상의 변환공간 색인으로서, 이미 구축된 원공간 색인을 구조적으로 변경하지 않고서 별도의 추가비용 없이 가상의 변환공간 색인으로 해석할 수 있게 한다. 실험 결과, 변환공간 뷰 조인알고리즘은 R 트리를 원공간에서 조인하는 알고리즘들과 비교하여 디스크 액세스 횟수 측면에서 최대 43.1%까지 더 좋은 성능을 보인다. 본 논문의 가장 중요한 공헌은 R 트리와 같이 널리 사용되는 원공간 색인을 변환공간 뷰라는 새로운 개념을 통하여 변환공간에서 해석하여 사용할 수 있음을 보인 것이다. 우리는 이 새로운 개념이 다양한 공간 질의 처리 알고리즘들이 변환공간에서 새롭게 개발될 수 있는 프레임워크를 마련했다고 믿는다.

This study explored the perception of transplanted English prosody by thirty American and Korean, male and female listeners. The English utterances of various sentence types produced by Korean and American male speakers were employed to transplant the American prosody contours to Korean English utterances. Then, the thirty subjects were instructed to rate the transplanted prosodic components. Results showed that the interactions between the three factors (e.g., rater groups & transplantation types; transplantation types & sentence types; rater groups & transplantation types & sentence types) turned out to be meaningful. Both Americans and Koreans perceived the effectiveness of the combined effect of transplanted duration and pitch or duration and pitch and intensity. However, when perceiving individual prosodic components, Americans and Koreans showed different perceptual ratings. As for the overall prosody change, Americans perceived the change of intensity in a significant way but Koreans did not because intensity is not a crucial semantic factor in Korean. Americans rated the transplantation of duration alone as ineffective while Koreans rated otherwise. This was explained by the difference between English and Korean. The difference of perspective was also significant with different sentence types, especially with the three sentence types that had speech rates slower than other sentence types. A slower speech rate intensified the mismatch between the transplanted duration and the original pitch causing a negative impression on American listeners whereas this did not affect Korean listeners. Pedagogical implications of the findings are discussed.

In order to analyze the vibro-impacts in the torsional system, several clearance types of nonlinearities should be included with the analytical or numerical method. These kinds of nonlinear factors can cause the errors while the system is calculated specifically with the numerical method, also it might take too long to get right answers with the every nonlinearity in the original system. Therefore, there are several methods developed for the sake of overcoming the deficiency of the analysis with the original system and saving the calculating time. The original system can be reduced by keeping the system characteristics such as from 14 to 6 DOF. Especially, since the torque flow in the torsional system is connected with the specific gear ratios, the original system can be transferred into the simpler system corresponding to each gear ratio rather than the original system, which can also show the same system characteristics such as the natural frequencies and the mode shapes. By using the reduced system, the calculating time can be saved and the redundant nonlinear effects for the system analysis can be ignored without any numerical errors.

This study explored the perception of transplanted Korean prosody by NE (Native speakers of English) and NK (Native speakers of Korean) listeners. The Korean utterances of various sentence types produced by NE and NK were employed to transplant the original Korean prosody contours to the Korean utterances read by NE. Then, other NE and NK were instructed to rate the transplanted prosodic components. Results showed that the interactions between the two rater groups with the three factors (e.g., transplantation types & rater groups, sentence types & rater groups, sentence length & rater groups) turned out to be meaningful. Both rater groups preferred the combined effect of transplanted prosodic components (e.g. DP, DPI) to that of individual transplantation (e.g. I, D, P). Compared to NK, NE were more sensitive to duration change than pitch change whereas NK showed equal preference to the both. In sentence types such as De, Ex, Im, and Ta, NE perceived higher similarity than NK.

본 연구는 한국 고추의 전래 역사와 어원에 대한 고찰의 일부이다. 한글명에 대한 최초의 기록은 "훈몽자회(訓蒙字會)"로서 한자어 椒와 함께 '고쵸'로 언해되어있다. 이에 따라 '고쵸'로 기록된 초(椒)의 기록을 찾아 분석하여 본 결과 "훈몽자회" 그 이전에도 우리나라에 다양한 종류의 고추가 있었음을 확인할 수 있었다. "홍재전서(弘齋全書)"(1799)에는 정조가 김달순에게 초(椒)의 종류에 대해 물었으며, 김달순은 초의 종류가 매우 많다고 하면서 촉초(蜀椒), 진초(秦椒), 단초(丹椒), 대초(大椒), 호초(胡椒) 같은 것들이 있다고 하였다. 이 논문에서는 촉초, 진초, 단초, 대초, 호초가 이름은 같으면서 약재의 품종과 고추의 품종이 있는 공통점을 발견하여 이를 초(椒)의 특징으로 보았고, 이 초(椒)는 "훈몽자회" 등의 고문헌에서 한글로 '고쵸'로 언해되어있음을 발견하고 '고쵸'로 기록된 초(椒)의 종류를 찾아본 결과 김달순이 말한 촉초, 진초, 단초, 대초, 호초 이외에 고초(苦椒), 번초(蕃椒), 남만초(南蠻椒), 만초(蔓椒)가 있음을 확인하였다. 이들은 모두 고쵸로 언해되어있으며, 이 고쵸는 고추를 의미한다. 결론적으로 촉초, 진초, 단초, 대초, 호초, 번초, 남만초, 만초를 모두 고쵸라고 부른 점으로 보아 국내에 이미 고쵸(고추)가 있었고, 외국(촉나라, 진나라, 호나라, 번우, 남만 등)과의 교류를 통하여 다양한 품종의 고추가 국내에 유입되었고, 고쵸의 한자 조어(造語)의 필요성에 따라 苦椒라는 한자가 만들어졌음을 알 수 있다.
