The purpose of this study was to examines the changes in Chinese women's clothing resulted from the introduction of Western culture in the first hal# of the 20th century in terms of Chinese view of the world and their attitude towards European culture. The clothes are divided into four types according to their characteristics : traditional Chinese type, China-Europe adjustment type, China-Europe blend type and European type. As for the research method, both literature and visual data are examined. The traditional Chinese type showed changes only in the width and length retaining the features of the traditional qipao until the 1910s. The China-Europe adjustment type used the same flat pattern making of traditional Chinese dress while imitating only the appearances of European one-piece, two-piece and three-piece dresses. It also was presented with European accessaries and hair-styles. The China-Europe blend type, starting to appear with the introduction of the three-dimensional pattern making from the Europe in the 1930s, showed a perfect mixture of European and traditional Chinese costumes in the early 1940s when the Chinese learned and adapted the European pattern making. The European type was the most modernized designs using a variety of European-style details and constructions as the traditional clothing started to have unrestricted European-style changes. Great significance can be found in the fact that the Chinese modified their garments by themselves using the pattern mating they learned from the Europe.

The purpose of this study was to provide some preliminary results on application of 3D scan data of head shapes to the hat design and pattern-making. This paper defined necessary measurement items and concepts in 3-dimensional images of head shapes. And also it presented the methodology to pattern-making of 6-piece crown hat based on 3D data. It used the data of Size Korea to pick up and choose a head shape model with the average head size of Korean women in their twenties. Main results were: 1. The 3D scan data of head shape was better than the 1 dimensional measurement data. Because I could establish a hat pattern-making theory by the 3D scan data of head. 2. The 3D scan data provided the basis for conceptualization of basic measurement points and items for a better fit of hats as well as the definition of the basic hat circumference. 3. This presented a methodology for analyzing out head shape by 3D scan data, and allowed the derivation of the basic hat circumference from the maximum head circumference. 4. As the 6-piece Crown cloche hat made by this method fitted the head shape model perfectly, this methodology could suggest potential applicability to various hat design.

In this paper, we propose a method for predicting a user's location based on their past movement patterns. There is no restriction on the length of past movement patterns when using this method to predict the current location. For this purpose, a modified search tree has been devised. The search tree is constructed in an effective manner while it additionally learns the movement patterns of a user one by one. In fact, the time complexity of the learning process for a movement pattern is linear. In this process, the search tree expands to take into consideration more details about the movement patterns when a pattern that conflicts with an existing trained pattern is found. In this manner, the search tree is trained to make an exact matching, as needed, for location prediction. In the experiments, the results showed that this method is highly accurate in comparison with more complex and sophisticated methods. Also, the accuracy deviation of users of this method is significantly lower than for any other methods. This means that this method is highly stable for the variations of behavioral patterns as compared to any other method. Finally, 1.47 locations were considered on average for making a prediction with this method. This shows that the prediction process is very efficient.

This paper proposes a new call admission control scheme utilizing an inverse fuzzy vector quantizer(IFVQ) and neural net, which combines benefits of IFVQ and flexibilities of FCM(Fuzzy-C-Menas) arithmatics, to decide whether a requested call that is not trained in learning phase to be connected or not. The system generates the estimated traffic pattern of the cell stream of a new call, using feasible/infeasible patterns in codebook, fuzzy membership values that represent the degree to which each pattern of codebook matches input pattern, and FCM arithmatics. The input to the NN is the vector consisted of traffic parameters which is the means and variances of the number of cells arriving inthe interval. After training(using error back propagation algorithm), when the NN is used for decision making, the decision as to whether to accept or reject a new call depends on whether the output is greater or less then decision threshold(+0.5). This method is a new technique for call admi sion control using the membership values as traffic parameter which declared to CAC at the call set up stage, and is valid for a very general traffic model in which the calls of a stream can belong to an unlimited number of traffic classes. Through the simmulation. it is founded the performance of the suggested method outforms compared to the conventional NN method.

Micro-fabrication techniques such as lithography and LIGA processes usually require large investment and are suitable for mass production. Therefore, there is a need for a new micro-fabrication technique that is flexible and more cost effective. In this paper a novel, economical and flexible method of producing micro-pattern on silicon wafer is presented. This method relies on selective removal of mask by mechanical cutting. Then micro-pattern is produced by chemical etching. V-shaped grooved of about 3 ${\mu}m$ wide and 2 ${\mu}m$ deep has been made on ${SiO_2}m$ coated silicon wafer with this method. This method may be utilized for making microstructures in MEMS application at low cost.

본 논문은 유사랜덤 방식의 BIST를 기반으로 하여 스캔 shifting시의 transition을 획기적으로 줄여 주었던 transition freezing 기법과 새롭게 제안하는 고장검출율 100%를 위한 pattern mapping 기법을 결합한 효과적인 저전력 BIST구조에 대해 제안한다. Transition freezing 기법으로 생성된 고연관의 저전력 패턴은 패턴 인가 초기에는 많은 수의 고장을 검출해 내지만, 패턴의 수가 점점 늘어날수록 랜덤 저항 고장의 증가로 인해 추가적인 고장 검출에는 한계가 있었다. 이러한 비검출 고장에 대해 ATPG를 통한 테스트 패턴을 생성하여, 고장을 검출하지 못하는 frozen pattern과 mapping을 함으로써 기 생성된 패턴을 재활용하여 인가되는 패턴의 수와 테스트 시간을 줄임으로써 전력 소모량을 줄일 수 있었다.
