This study is aimed to increase the possibility of using the Christopher Alexander's pattern language. The methodology of this study is (i) to analyze the pattern language by using the network analysis tool in order to understand the complicate network structure of the pattern language, and (ii) to apply the Alexander's method of using the pattern language by using the network analysis tool (Gephi) and to examine the feasibility of the network analysis tool as a tool for using the pattern language. Firstly, as a result of analysing the pattern language, (i) the pattern language classified by pattern number is distinguished by the patterns of towns, buildings and construction, among which the pattern of buildings plays a key function in the networks; (ii) the buildings functions a medium connecting between the towns and the construction; and (iii) the pattern language is divided into 6 sub-modules, through which the user can select a pattern. Secondly, the result of using the network analysis tool as a tool for using the pattern language (i) suggests the new method of using the pattern language by using the network analysis tool (Gephi); (ii) makes it possible to easily figure out the characteristics of the links between the patterns; and (iii) increases the completeness of the pattern language by making it easy to find out the sub-patterns in selecting a pattern.

The purpose of this study was to examine the inconvenience when putting on stretchable pants and to analyze the whole actual conditions of making of the lining fabrics. For this study, we conducted a survey of women in their twenties and collected the basic data and master pattern through material of a woman's wear brand and the interview and questionnaires. The results of this study were as follows. First, the survey result for the woman consumers it showed that the most uncomfortable problem about the lining of pants was not sufficient stretch as much as the out-shell. Secondly, it was shown that many brands(46.7%) were using the lining fabrics of stretch clothes mixed with 'non-stretch fabrics' and 'stretch fabrics'. The result of lining pattern making for the stretch pants showed that the ease of the lining fabrics was 0 to 4cm in the hip girth more than out-shell. The ease in crotch width was 0 to 1.3cm for lining fabrics. But in the stretch lining fabrics the ease for front crotch width was 0 to 1cm more than out-shell. The lengths of crotch rising were -0.7 to 1.3cm for the non-stretch lining fabrics and -1 to 1cm for the stretch lining fabrics.

데이터마이닝에서 시계열 데이터로부터 순차패턴을 발견하는 연구는 사건이나 아이템이 주로 연구되어왔지만, 최근에는 설비의 상태를 알 수 있는 센서와 같은 수치 값의 형태를 가지는 분야에 관심을 가지게 되었다. 그러나 수치 형태의 데이터는 패턴을 만드는 동안 동일한 값을 가지는 경우가 거의 없기 때문에 기존의 사건이나 아이템 등으로 변환될 수 있는 패턴요소의 특징을 만드는 것이 가장 중요하다. 이러한 패턴요소를 발견하는 지금가지 방법은 이동 윈도우와 클러스터링을 사용하는 방법을 적용하였는데, 이러한 방법은 다양한 윈도우의 크기와 클러스터 값을 적용하여 반복적으로 작업을 하며, 찾아진 결과를 해석하는데도 많은 문제가 있다. 본 연구는 수치 값을 가진 데이터를 벡터의 형태로 만들어 패턴요소를 만드는 방법을 제시한다. 이렇게 만들어진 패턴요소는 전체 데이터를 사용하는 것 보다 이해되기 쉽고 보다 빠르게 순차패턴을 찾을 수 있다. 벡터로 변환된 패턴요소는 각도와 크기를 가지는데 우리는 이들 벡터들의 상호 연관성을 정의하고, 이들 연관성을 이용하여 순차패턴을 찾는 방법을 제시한다.

This study develops a traditional green fabric pattern design through an apparel CAD system. The method used simulated stage costumes and evaluated the consumer satisfaction connected with a 3D fitting system. The results are as follows. Computerization of the pattern making process can provide higher accuracy and efficiency in apparel pattern making and marking for green fabrics. A Stage costumes design was developed; subsequently, the developed dress patterns are automatically depicted to the input of the body size of the consumer and marked using marking program. This results show that it has an effect on narrow and expensive green fabrics. Stage costumes design can make a simulation by a 3D Fitting system. The results of this study can provide higher consumer satisfaction through a survey of 30 consumers. Stage costumes should attract the sympathy of the spectators. The Acceptance of Andong region's traditional beauty is required. We found that a relationship of performance and clothes, physical functionality and beauty of costumes, possibility of commercialization, and the possible use of a 3D Fitting system use are evaluated. A continuous study of regional culture resources is required since there is a significant possibility for the long-term development of stage clothes.

The pattern making of the tight-fitting collars which often used in diving suits, dance wear, or cycle wear has not been fully established. To develop tight-fitting collar pattern directly from 3D images from the representative somatotypes, dressforms developed by Jaeun Jung were used. The 3D scan data of the four male dressforms were obtained using Exyma-1200. Triangle Simplification and the Runge-Kutta method were applied to reduce the 3D scan data points and to make the segmented triangular patches in a plane from 3D data. As results, apparent differences between the tight-fitting collar patterns obtained from the 3D scan data and the ordinary 2D collar patterns were found around the center back line. The curvatures of the center back line were higher in all types of the tight-fitting collar than in the ordinary collar pattern. Relative differences in the shape of collar lines among four representative Korean men were reported. To fit the curved shape of the back neckline, 1.8 cm should be reduced from the upper neckline in average. We suggested the direct pattern making method for the 2D tight-fitting collar patterns considering the 3D shape of various types of men's dressform.

It can be important framework data to monitor the change of land-use pattern of river boundary in design and management of river. This study analyzed the change of land-use pattern of Gab- and Yudeung River using time-series aerial images. To do this, we carried out radiation and geometric correction of image, and estimated land-use changes in inland and floodplain. As the analysis of inland, the ratio of residential, commercial, industrial, educational and public area, that is urbanized element, increases, but that of agricultural area shows a decline on the basis of 1990. Also, Minimum Distance Method, which is a kind of supervised classification method, is applied to extract water-body and sand bar layer in floodplain. As the analysis of land-use, the ratio of level-upped riverside land and water-body increases, but that of sand bar decreases. These time-series land use information can be important decision making data to evaluate the urbanization of river boundary, and especially it gives us goodness in river development project such as the composition of ecological habitat.

The human body, which is composed of concave and convex curvatures, makes it difficult to transfer into 2D patterns directly from 3D data. In previous studies. Jeong, et al.(2004) suggested the block method was fester and easier when dealing with the triangular patches of male's upper dress form. Although the block method is useful to make a pattern, the information(area, length, etc.) from a 2D pattern would be different depending on the direction of the block method. As a result horizontal and diagonal block methods were suggested as optimal methods for 2D tight-fitting patterns. These block methods were closer to the original area of the 3D scan data than the vertical block method. The total area of the 2D pattern obtained by the horizontal and diagonal block methods showed little differences. In case of the horizontal and diagonal block methods, the total error of the 2D pattern area ranged from $0.01\%\~0.25\%$. In comparing the length of the 2D pattern with that of the 3D scan data, the obtained 2D pattern was $0.1\~0.2cm$ shorter than the 3D scan data, which was within the acceptable range of errors in making clothes. 3D space distribution images between the body surface and the experimental clothing were also measured and $3\%$ enlargement of the original pattern was verified as the adequate adjustment.

Most machines lose a lot of energy due to friction. Wear due to friction also reduces performance. Therefore, it is important to reduce friction on the surface to improve energy efficiency and decrease wear. Surface texturing refers to making patterns on the surface for reducing friction. There are many surface texturing methods, such as using lasers, abrasive jet machining, and so on. Recently, mechanical manufacturing methods, such as cutting and grinding, have been highlighted. Among them, the grinding method has the advantage of making patterns in large areas quickly. Therefore, it is appropriate for surface texturing on large machines. This paper is a study on the slope change of the surface texturing pattern using grinding. Therefore, we researched the slopes of the patterns corresponding to "spindle speed and feed rate" and "curvature of workpiece surface" using a mathematical model and experiment. As a result, we made a proper mathematical model concerning our research. Therefore, using the mathematical model in this paper, we could predict the slope change of the pattern according to grinding conditions.
