Research interest has strongly focused on developing a method for effectively transmitting bio-signals over a distance using a wireless wearable device. In this paper, we describe a procedure for the design and fabrication of a wearable antenna based on embroidering conductive threads to clothing capable of transmitting electrocardiogram signals. 3D electromagnetic simulation software and embroidery software were used to design and fabricate the conductive thread-based antenna, respectively. The measurement results show that the reflection coefficient of the fabricated antenna prototype exhibits excellent antenna impedance matching characteristics of less than -10dB in the Zigbee 2.4GHz frequency band. We also verified that the electrocardiogram data could be effectively received and monitored in real-time by a receiver 220m away from the transmitter.

It goes without saying that Yi Mae-Bang, as the sole owner of two of the intangible cultural assets including No. 27 Seungmu in 1987 and No. 97 Salpuri Chum, is a top-notch Korean traditional dancer. Moreover, in regards to traditional clothing, he is also known as the only traditional dancer who directly performs on stage as well as analyzes traditional clothing in order to apply them into his own dance performances by designing and producing them to meet his artistic spirit. In order to examine how Yi Mae-Bang's unique and creative stage clothing was developed, and what kind of process it went through to possess its unique style, which draws the attentions of people with its harmony of beauty and dance, this research first examined the change of the composition through the yearly picture data. Before 1984, the composition of the Salpuri Chum clothes changed by putting on 'Jeogori' on the 'Mudong-Bok' without the 'Kweia' (sleeveless), and in 1999 'Mudong-Bok' became widened with the decoration of embroidered hem making it more attractively colorful. after 2000 it became more splendidly adorned by embroidering hem on widened Mudong-Bok and tucking 'Kweja' in the layers which created silhouette like a dress that is seemingly wider and luxuriant than a skirt. One of notable features of Yi Mae-Bang's Salpuri is that its cloth and cuff ribbons are lightly colored in different colors enclosing the tip part. As for the ribbons, it was also changed as time went by from direct-cutting of the cloth just like the A-line of Mudong-Bok to drawing a diagonal line less than 5cm above the ribbon and 8cm below the ribbon so that it takes the form of getting widened as it gets to the lower part, and its length was also elongated in proportion to that of the bottom of Mudong-Bok.

The contents of clothing and textiles area of elementary home economics textbooks from 1948 to 1955 were investigated. Home economics of elementary school education in those days corresponds to practice acts of elementary school education in present. Practical acts has the all-around concepts of the agriculture, industry and home economics Also the knowledge or skill for actual life are teamed. Practical acts education was started from lessons of sewing for women under title of 'jaebong'. It can be said that practical acts education was started from clothing and textiles area. The home economics elementary textbooks of the year 1948 were composed of 21 units for 5th grade and 22 units for 6th grade. The textbook for 5th grade of 1953 was composed of 19 units, and one for 6th grade of 1955 was composed of 18 units. The clothing and textiles area accounts for 38.6% in 5th grade textbook, for 32% in 6th grade textbook of 1948 and for 31% in 5th grade of 1953 and 6th grade textbooks of 1955. The textbook contents of clothing and textiles area were classified into five fields of sewing, knitting. patching, embroidering and care. In 1948, textbooks were placed a great deal of weight on sewing field education as 7 units of 15 units. The 7 units for sewing fields have suitable connection to develop. But, in the case of knitting, patching or care, just groundwork of each field was included for application to actual life without vertical connection. The contents of textbooks for clothing and textiles area in 1953 and 1955 were much alike with those in 1948.

The purpose of this study is to explore the conceptions of children and their activities in everyday lives during the late period of the Goryo Dynasty. The historical method was used and the materials for analysis were the literatures written from the late thirteenth century to the fourteenth century in the Goryo Dynasty, such as 'the Ikjaijip'(익재집), 'Mokeunjip'(목은집), 'Yangchonjip'(양촌집). According to the results, the perspective on the nature of a chad was that children were inherently good with the true character which was given from natural laws and that each child was born with different natural endowment. Also, the notions on child development were that the infancy was a pure and perfect period which us not contaminated by temperament and worldly desires, instead of the developmental model that childhood is as a stage and the child must develop from the state of incompetence to the state of maturity. In addition, there were the principles for development that were keeping the innate ideal state and fostering it from the earliest time as infants were born with innate ideal state or ability. The concepts of children's characteristics were considered that they were inclined to make much noise and movement, but to have the plain and straightforward expressions and consistency in their feelings and everyday activities. And intelligent abilities for learning were often considered as desirable traits. In everyday lives, children did the household chores such as caring for livestock and silkworms or embroidering. Among their games were exploring activities, free plays using natural materials, pretend-plays, bamboo-stilts riding, and Yutnori.

The purpose of this study is to present a classification system of the hand-made and machine-made lace according to the configuration method and re-make the category and definition of lace to consider the emergence and development of major laces techniques. The re-made category and definition of the lace is as follows. The lace usually consists of ground and motifs, however, the techniques of netting and sprang are suitable for making ground than motif, so I think it is appropriate to exclude them from the category of the lace. Many scholars are excluded openwork embroidery fabric from the category of the lace. But, an openwork embroidery fabric is the basis of a needle point lace called true lace and is consist of motif and ground. I think it is appropriate to include it in the category of the lace. I think it is also appropriate to include in the category of the lace that the eyelet embroidery fabric which mimics the openwork embroidery fabric in the machine. Lace is redefined that a fabric with openwork decoration consists of motif and ground, constructed by a variety of ways such as plaiting, twisting, looping, knotting of threads or embroidering by hand or machine. The classification of the lace is presented as follows. Hand-made lace is classified bobbin lace, needle point lace, embroidery lace, knotted lace, crochet lace, and knitting lace. Machine-made lace is classified raschel lace, leaver lace, torchon lace, and machine-made embroidery laces which include tool lace, eyelet embroidery lace, chemical lace, etc.

This paper reviews the recent development of electronic textile technology, mainly focusing on chip-textile bonding. Before the chip-textile bonding, a circuit on the textile should be prepared to supply the electrical power and signal to the chip mounted on the fabrics. Either embroidery with conductive yarn or screen-printing with the conductive paste can be applied to implement the circuit on the fabrics depending on the circuit density and resolution. Next, chip-textile bonding can be performed. There are two choices for chip-textile bonding: fixed connection methods such as soldering, ACF/NCA, embroidery, crimping, and secondly removable connection methods like a hook, magnet, zipper. Following the chip-textile bonding process, the chip on the textile is generally encapsulated using PDMS to ensure reliability like water-proof.

In this study, we investigated the necessary mechanical properties of conductive multifilament yarns for fabricating the electrodes of biosignal measurement pressure and stretch textile sensors using embroidery. When electrodes and circuits for smart wearable products are produced through the embroidery process using conductive multifilament yarns, unnecessary material loss is minimized, and complex electrode shapes or circuit designs can be produced without additional processes using a computer embroidering machine. However, because ordinary missionary threads cannot overcome the stress in the embroidery process and yarn cutting occurs, herein, we analyzed the S-S curve, thickness, and twist structure, which are three types of silver-coated multifilament yarns, and measured the stress in the thread of the embroidery simultaneously. Thus, the required mechanical properties of the yarns in the embroidery process were analyzed. In the actual sample production, cutting occurred in silver-coated multifilament rather than silver-coated polyamide/polyester, which showed the lowest S-S curve. In the embroidery process, the twist was unwound through repetitive vertical movement. Further, we fabricated a piezoresistive pressure/tension sensor to measure gauge factor, which is an index for measuring biological signals. We confirmed that the sensor can be applied to the fabrication of embroidery electrodes, which is an important process in the mass production of smart wearable products.

Landfill require special care due to the dangers of nearby surface water and underground water pollution caused by leakage of leachate. The leachate does not leak due to the installation of the geomembrane but sharp wastes or landfill equipment can damage the geomembrane and therefore a means of protecting the geomembrane is required. In Korea, in accordance with the waste control act being modified in 1999, protecting the geosynthetics liner on top of the slope of landfill and installing a drainage layer to fluently drain leachate became mandatory, and technologies are being researched to both protect the geomembrane and quickly drain leachate simultaneously. Therefore, this research has its purpose in studying the drainage functions of leachate and protection functions of the geomembrane in order to examine the application possibilities of Geo-Multicell-Composite (GMC) as a Leachate Collection Removal and Protection System (LCRPs) at the slope on top of the geomembrane of landfill by observing methods of inserting filler with high-quality water permeability at the drainage net. GMC's horizontal permeability coefficient is $8.0{\times}10^{-4}m^2/s$ to legal standards satisfeid. Also crash gravel used as filler respected by vertical permeability is 5.0 cm/s, embroidering puncture strength 140.2 kgf. A result of storm drain using artificial rain in GMC model facility, maxinum flow rate of 1,120 L/hr even spray without surface runoff was about 92~97% penetration. Further study, instead of crash gravel used as a filler, such as using recycled aggregate utilization increases and the resulting construction cost is expected to savings.

Goli-su is the innovative special kind of the embroidery technique, which combines twining and interlacing skill with metal technology and makes the loops woven to each other with a strand. The loops floating on the space of the ground look like floating veins of sculpture and give people the feeling of the openwork. This kind of characteristic has some similarities with the lacework craft of Western Europe in texture and technique style, but it has its own features different from that of Western Europe. It mainly represents the splendid gloss with metallic materials in the Embroidered cloth, such as gold foil or wire. In the 10th century, early days of Goryo, we can see the basic Goli-su structure form of its initial period in the boy motif embroidery purse unearthed from the first level of Octagonal Nine-storied Pagoda of Woljeong-sa. In the Middle period of Joseon, there are several pieces of Goli-su embroidered relic called "Battle Flag of Goryo", which was taken by the Japanese in 1592 and is now in the Japanese temple. This piece is now converted into altar-table covers. In 18~19th century, two pairs of embroidered pillows in Joseon palace were kept intact, whose time and source are very accurate. The frame of the pillows was embroidered with Goli-su veins, and some gold foil papers were inserted into the inside. The triangle motif with silk was embroidered on the pillow. The stitch in the Needle-Looped embroidery is divided into three kinds according to comprehensive classification: 1. Goli-su ; 2. Goli-Kamgi-su ; 3. Goli-Saegim-su. From the 10th century newly establishing stage to the 13th century, Goli-su has appeared variational stitches and employed 2~3 dimensional color schemes gradually. According to the research of this thesis, we can still see this stitch in the embroidery pillow, which proves that Goli-suwas still kept in Korea in the 19th century. And in terms of the research achievement of this thesis, Archetype technology of Goli-su was restored. Han Sang-soo, Important Intangible Cultural Heritage No. 80 and Master of Embroidery already recreated the Korean relics of Goli-su in Joseon Dynasty. The Needle-Looped embriodery is the overall technological result of ancestral outstanding Metal craft, Twining and Interlacing craft, and Embroidery art. We should inherit, create, and seek the new direction in modern multi-dimensional and international industry societyon the basis of these research results. We can inherit the long history of embroidering, weaving, fiber processing, and expand the applications of other craft industries, and develop new advanced additional values of new dress material, fashion technology, ornament craft and artistic design. Thus, other crafts assist each other and broaden the expressive field to pursue more diversified formative beauty and beautify our life abundantly together.
