This stuffy is to understand the symbolic meaning of Korean traditional animal Patterns, to analyze their figurative characteristics focusing on fabric relics of Chosun Dynasty, and to search their internal beauty as well as their external beauty. Animal patterns can be classified as Individual type, the type that only animal patterns are used, and Compound type, the type that animal patterns are used with other patterns. The Individual type was not found at all. Only the Compound type, compounded with two or three other patterns, were found. Among the other patterns used in the Compound type, botanical patterns and heaven-and-earth-shaped patterns were the majority while letters patterns were rarely used. Bird patterns take enormously large part of the animal patterns. In terms of the arrangement, animal patterns are classified as Dense type, Sparse type, and Picturesque type.'rho three types are almost equal in their quantity. Picturesque type is found comparatively a lot. Animal patterns are much more frequently used in female clothes than in male clothes. For female clothes, they are mostly used in some parts of the clothes with ornamental effect. But, for male clothes, they are mainly used all over the fabric by weaving animal patterns on it. Not just their external beauty, animal patterns have also internally beautiful characteristics, such as keeping away from wicked ghosts, hoping for good luck, emblematic features, having ideological meanings, and so on.

Since COVID19 virus has been occured, variety steps of the quarantine guidelines were enacted. In step 2.5, eating in a cafe was prohibited and only takeout was permitted, but the government has changed several rules. So now people can have a dissert or coffee in the cafe. Though the government adviced available staying time as 1 hour, it is not obeyed often except superstore, and even the management depends on handwriting. In this paper, we implemented a blockchain system to use for this case. This system is implemented with using hyperledger fabric, the blockchain framework which is made by IBM. For a test, 1 organization is in the system and chaincode is installed to the organization to run the system. We expect the certain effect to the quarantine via this system.

The purpose of this study is to develop the effective customized elderly fashion marketing process based on the web site, where older customer will be able to choose various fabrics and to try them out. This aims to establish new prototype of internet shopping mall for customized elderly fashion clothing. In this study, new method of product presentation on the online shopping mall is proposed to offer product information through 3D virtual reality. With the online shopping mall(SATC Mall) as a showcase, we presented virtual mapping system so that it enable the customers to select the fabrics and to see exactly how chosen fabric will look when applied to image of clothing. As an initial test of the application of simulation to measure 3D visualization of product, mapping software Vision Easy Map Pro Version 6.0(NedGraphics) Vision Easy Map Viewer Version 5.0(NedGraphics) were chosen and applied. By using this mapping system, the fabric change of the apparel product could be made on the internet shopping web site. However, this approach has been successful applied for presenting and customizing garment products. Future research will focus on the integration of mapping coordination into SATC Mall.

Currently smart textile market is rapidly expanding and the demand is increasing integration of an electronic fiber circuit. The garments are an attractive platform for wearable device. This is one of the integration techniques, which consists of is the selective introduction of conductive yarns into the fabric through knitting, weaving or embroidering. The aim of this work is to develop a golf bend driven prototype design for an attachable Arduino that can be used to assess elbow motion. The process begins with the development of a wearable device technique that uses conductive yarn and flex sensor for measurement of elbow bending movements. Also this paper describes and discusses resistance value of zigzag embroidery of the conductive yarns on the tensile properties of the fabrics. Furthermore, by forming a circuit using an Arduino and flex sensor the prototype was created with an assistance band for golf posture training. This study provides valuable information to those interested in the future directions of the smart fashion industry.

This study was performed to analyze the wearing practice and the purchasing characteristics of brassieres in order to offer basic data to produce superior brassiere and to improve the wearing comfort. The questionnaire were 146 Korean college female students. For data analysis, descriptive analysis, crosstabs, factor analysis and one-way ANOVA were used. The results were as follows, first, most subjects didn't know the sizing system of brassiere and their own breast size. So the degree of satisfaction of wearing brassiere was low than subjects who knew their own breast size. And they replied that the most unsatisfaction factor was brassiere size. Second, when subjects decided to purchase a brassiere they considered size, design, color, cost, fabric and brand and so on. Among them size and design were considered the most important. Third, the subjects who wear brassiere all day long, they considered wearing comfort and cost rather than design and collar. Therefore, the markets with brassieres would be able to segmented based on consumers' characteristics. Firth, the subjects were dissatisified at size, the taking off wire and shape modification after washing. And they requested the development of various size, fabric and cost improvement and fittness of brassieres. These results imply that to improve the wearing comfort of brassiere, it is so important to produce and develop various types of size first of all. And consumers should know size system of brassiere and their own breast size.

The purpose of this study was to examine the effects of the structural properties of plain knit fabrics on the subjective perception of textures, sensibilities, and preference among consumers. This study, then, aimed to provide useful information with respect to planning and designing knitted fabrics by predicting the subjective characteristics analyzed according to their structural properties. For this purpose, we employed statistical analysis tools, such as factor and regression analysis and an adaptive-network-based fuzzy inference system(ANFIS), thereby combining the merits of fuzzy and neural networks and presupposing a non-linear relationship. Through factor analysis, we also categorized the subjective textures into 'roughness', 'softness', 'bulkiness' and 'stretch-ability' with R2=70.32%: and categorized the sensibilities into 'Stable/Neat', 'Natural/Comfortable' and 'Feminine/Elegant' with R2=68.12%. We analyzed subjective textures, sensibilities, and preference with ANFIS, assuming non-linear relationships; consequently, we were able to generate three or four fuzzy rules using wool/rayon fiber content and loop length as input data. The textures of roughness and softness exhibited a linear relationship, but other subjective characteristics demonstrated a non-linear input-output relationship. Compared with linear regression analysis, the ANFIS exhibited had higher predictive power with respect to predicting subjective characteristics.

Avionic databuses fulfill a critical function in the connection and communication of aircraft components and functions such as flight-control, navigation, and monitoring. Ethernet-based avionic databuses have become the mainstream for large aircraft owning to their advantages of full-duplex communication with high bandwidth, low latency, low packet-loss, and low cost. As a new generation aviation network communication standard, avionics full-duplex switched ethernet (AFDX) adopted concepts from the telecom standard, asynchronous transfer mode (ATM). In this technology, the switches are the key devices influencing the overall performance. This paper reviews the avionic databus with emphasis on the switch architecture classifications. Based on a comparison, analysis, and discussion of the different switch architectures, we propose a new avionic switch design based on a time-division switch fabric for high flexibility and scalability. This also merges the design concept of space-partition switch fabric to achieve reliability and predictability. The new switch architecture, called space partitioned shared memory switch (SPSMS), isolates the memory space for each output port. This can reduce the competition for resources and avoid conflicts, decrease the packet forwarding latency through the switch, and reduce the packet loss rate. A simulation of the architecture with optimized network engineering tools (OPNET) confirms the efficiency and significant performance improvement over a classic shared memory switch, in terms of overall packet latency, queuing delay, and queue size.
