Pythagorean fuzzy sets (PFSs) are capable of modelling information with more uncertainties in decision-making problems. The essential feature of PFSs is that they are described by three parameters: membership function, non-membership function and hesitant margin, with the total of the squares of each parameter equal to one. The purpose of this article is to suggest some new similarity measures and weighted similarity measures for PFSs. Numerical computations have been carried out to validate our proposed measures. Applications of these measures have been applied to some real-life decision-making problems of pattern detection and medicinal investigations. Moreover, a descriptive illustration is employed to compare the results of the proposed measures with the existing analogous similarity measures to show their effectiveness.

Exaggerations have always been seen in the past and present. In the past, they represented wealth and high social status, but now they are being used to express one's beauty and personality. This has led to the diversity in design through widening each person's emotions. Likewise, exaggerations have been changed from the past to the present and so will they in the future. This study focuses on proposing patterns to enhance the utility and practical use of exaggerated jacket designs and its methods are based on documents and preceded studies. Pattern making is composed of drawing patterns and showing their forms by basting - which are a technique that is explained in this study's outcome - and the basic pattern is the style of Wan Suk. Suh. Jackets are made with exaggerating factors in the women's collections of 2011 F/W and are designed for various ages. With the knowledge of structuring a jacket, anyone could easily follow the instructions. In the end, he/she could elevate the ability to express, use practically and apply this idea in general fields of fashion industry.

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 purpose of this paper is to make it easy to reproduce the Pattern and sewing technique of men's coat in 18th century. which are modified in order to be made readily available in Korean theatre costume. The investigation was performed in three steps. 1st, The papers and records about development and change of men's coats were reviewed. End; The whole process of the way how to make a typical 18th century men's coats were sewn. 3rd ; The modification or revision into the more simplified pattern using by CAD system and sewing technique were suggested in detail. The size of the pattern in the original one, which we chose for this research, was generally small. with the side line being moved back a little. Moreover, arm movements were severely restricted because of the small arm-hole. The problems of original pattern were corrected by making both front and back pattern snug and side line being moved to the front, and making arm-hole wider. In the sewing technique, the simple way how to use of Padding, inter-linings and linings and to create the most noticeable figure of 18th century men's coat. This article may help theatre costume production in Korean performing art.

As basic materials in this research, 874 pieces of engraving that recorded the garment produced by diverse authors in the 17-18th century were collected among the collections of male and female garment in the engraving kept by National Library of France and 216 pieces of engraving were classified among them to observe justaucorps as stated in the materials. Since type of justaucorps in the 18th century can be classified by difference in shape and change through the above engraving materials in large quantity and the shape and composition can be compared and analyzed with other materials such as picture, stored garment, written materials without difficulty, the chronology can be composed by single type of justaucorps. Intending to understand the change in composition caused by type classification and pattern making as per analysis of type property of justaucorps, the men's upper garment in France in the 18th century. Checking change in design per from and materials, justaucorps of 1680-1700s was in silhouette where waist in the length above knee was adhered and slightly spread to lower part. In the type of 1710-1750s, waist adhered remarkably and many pleats were made under waist to produce volume of form that spread to lower part like skirt. In the type of 1760-1780s, straight silhouette was attached to whole body and end of front adjustment in slant line turns to rear part. The developmental aspect of construction can be checked by making pattern. Changing the cutting line of body plate to smoothly connect section and to try to adhere to the body, the development of simpler and delicate pattern production technique was confirmed.

The Purpose of this study is to present basic data for the more reasonable and successful home management through understanding decision-making pattern that is the degree of their participation in the decision-making and their joint decision-making. Also, this study is the preliminary research for more scientific and wider studies on the Decision-Making and Marital Power Structure in Korea. This study make investigation into decision-making and marital power which is published on the Journal of Korean home Economics Association and the Journal of Korean Home Management Association and thesis for a degree form 1960's to 1987. As a result, the higher wife's age, education level are the more their participation, The increase of the wife's participation in the decision-Making can be regarded as the affirmative phenomenon in the decision-making can be regarded as the affirmative phenomenon that their status are raised in home management and joint decision are carried out. In 1970's, not only the generalization of the empirical studies have been increased but also the general theories(resource theory, exchange theory, system theory ) have been developed.

The grinding plays a key role which decide the quality of a product finally. But the grinding process is very irregular, so it is very difficult to analyse the process accurately. Therefore it is very important in the aspect of precision and automation to reduce the idle time and to decide the proper dressing time by visualizing. In this study, we choose the direct method of observation by making use of computer vision, and apply pattern classification technique to the method of measuring the wheel surface. Pattern classification technique is proper to analyse complex surface image. We observe the change of the wheel surface by making use of the gray level run lengths which are representative prince in this technique.
