We examine primarily the existing study procedures for freeway weaving section by comparing speed estimates. Most methods have poor predictions because of neglecting the weaving vehicle influ-ence. In this study we develop the speed prediction equation considering the weaving influence area i.e, weaving box. Assuming that speeds outside weaving box are similar to speeds in freeway basic sec-tions we develop speed equation in box based on the field data. Moreover level of service criteria and weaving analysis precedure are proposed under the new speed prediction equation.

In weaving welding where a V groove exists, the heat input distribution is an important factor that determines the defectiveness of the bead shape, undercut and over-lap. In this study, the amount of heat input, which is determined by the welding current, voltage, speed and weaving conditions is calculated through mathematical development and numerical methods. Furthermore, the heat input distribution as a two- dimensional heat source was observed when applied to each groove.

The purpose of this paper is to find an optimal weaving connection method of sweater threads while weaving intarsia sweater by the genetic algorithm. The objective function was devised to minimize labor cost and lessen the amount of thread usage. In order to create the parental population group in the genetic algorithm, we developed five thread connection methods. Besides, elite chromosome screening methods for the offspring group was selected both to the whole chromosome thread elite and to a color-coded elite thread chromosome. Commonly used diamond pattern in Intarsia sweater manufacturing was applied to the experiments. The experimental results showed that thread system saved the labor and material costs than woven method under the existing software. When weaving Intarsia sweater in the field, we can apply the developed genetic algorithm to improve productivity of weaving connection method.

Objectives: This study was conducted to evaluate personal and area exposure of airborne nicotine during harvest and weaving tasks in tobacco farms. Methods: Nicotine was measured with NIOSH method 2551 and Passive sampler which was validated in previous papers for area and personal sampling. Results: The average (geometric mean) concentrations of nicotine with two different tasks in personal sample were 6.5 ${\mu}g/m^3$ (harvest), 32.6 ${\mu}g/m^3$ (weaving) and in area sample were 0.8 ${\mu}g/m^3$ (harvest), 57.2 ${\mu}g/m^3$ (weaving). There was significant difference in area sample between harvest and weaving task (p=0.000). Also, there was significant difference with personal sample (p=0.000). Conclusions: It was found that weaving task should be considered to be the first priority for reducing nicotine exposure.

In weaving welding where a V groove exists, the heat input distribution is an important factor that determines the defectiveness of the bead shape, undercut and over-lap. In this study, the amount of heat input, which is determined by the welding current, voltage, speed and weaving conditions is calculated through numerical methods. Furthermore, the heat input distribution as a two- dimensional heat source was observed when applied to each groove. Therefore, a heat input control algorithm is suggested to prevent the defects generated from undercut or over-lap, which was verified through an analysis of the heat input distribution.

This study is to understand the types and characteristics of wool fabrics of the Korea. It classifies the types of wool fabrics whose name can be found in the documents by their weaving methods and it researches their characteristics by type, time, usage, and pattern. In Wool fabric of the ancient age were there compound weaving fabric, such as Gyesoo. which is made with embroidery method, Gyegum, which is made with embroidery in gold threads, as well as general fabric, such as plain-weaved Gal, twill-weaved Sagal, gauze-weaved Mosa, Mora, etc. There were also various weaving methods, such pile-weaved Yung, tapestry-weaved Tabdung, or Guyoo, or Dahm, felt-weaved Jeon, etc. It was found in documents that wool fabric such as Gye, Jeon, Dahm were produced in Korea and China. In case of Korea, wool fabric was enormously developed in Koguryo, Shilla, Balhai, United Shilla. Koryo era. Particularly in Koguryo and Balhai, the stock-farming and hunting were the main parts of their occupation. In Koryo era, the weaving technique of wool fabric had made great development. The wool fabric was used not only in clothing but also in official hats, rugs. wall-tapestries, etc.

The purpose of this study is to categorize the typs of fabrics and to analyze weaving method and pattern design on the silk fabrics from Jang-Gi Jung s tomb. The conclusions of this research are as follows. 1) Among the 32 pieces of excavated clothes, 90% of them were made of silk fabric and 65% used patterned silk. I would assume, therefore, that the tomb was owned by a person of higher society who could afford the best clothes of the time. 2) The weaving methods of silk include tabby, twill damask with different direction (2/1 warp faced ground, 1/3$\cdot$1/4 weft faced pathern), self-patterned satin damask (4/1 warp faces ground, 1/4 weft faced pattern), and brocaded satin damask. 3) The arrangement of the motifs and the kinds of patterns on these silk fabric can be divided into two categories: first group is allover arrangement of peony or lotus and second group is the scattered arrangement of omen of luck. 4) Two pieces of fabric was stamped and the letters of the stamp make me to think about the possibility that the fabrics are from China. But to make this paint clear more relics of this kind should be excavated so that further research can be done.

This study tries to find out the special twine technique of flat string and refers to historical documents, records, artifacts of excavated articles, and real materials. In Japan weaved cloth is called Jomul or Jonue and these methods were brought to Japan from Korea during Aska Period(645${\sim}$710) and Nara Period(710${\sim}$794). Among those knot methods, the 1/1 knot was written as a Shillajo on a documentary record at Heian Period, Engisik, and Samdaesillok which is a historic document from King Saiya to King Gowooko(858${\sim}$887). Also 2/2 knot weaving was recorded as Goryeojo that the technique originated for a long time in Japan. During the Joseon Dynasty, Gunmok was written as Dahoi, and Gwangdahoe, which means wide and flat Gunmok, was the name of Dae(Belt). The frame for the twine Gwangdahoe is no longer in Korea, but only can be found in Japan as a Goraiwoochi loom for Shillajo and Goryeojo from Korea. There are currently artifacts by the techniques of Shillajo and Goryeojo that were excavated in 15${\sim}$17C in Korea. Therefore this study was looked into the artifacts from 6${\sim}$8C in $Sh{\"{O}}so$-in, and the features of Dae (Belt) weaved by Shillajo and Goryeojo case method. Gwangdahoe excavated artifacts in the mid Jeosun Dynasty was restored by the process of Goryeojo weaving method.

Different method of textile fabrication had existed since the ancient times, but the most dominant form was the 'weaving' method which embodies the cross fabrication of vertical and horizontal threads using special weaving machines (looms). In addition, fabrication methods like knitting, felt, and lace were commonly practiced while intertwinement methods like twisting, braiding, and knotting techniques were frequently used for weaving strings and braid type textiles. In the past, people did not pay attention to strings and braids because they were classified as non-textiles, but, in this paper, we have expanded the scope of definition of textile to include strings and braids, and seek to conduct in-depth research on various different intertwinement of textiles. The adaptation of intertwinement method in arts and crafts enables limitless creative works reflecting the ever-changing taste and style of the creator. This creativity is further broadened by the fact that intertwinement methods encompass no set patterns and the subject and shape of its creation is as broad as its artistic pursuits. We can infer the knowledge of our ancestors, their aesthetic taste, and the pattern of life from these creations. In addition, these creations can provide comfort and improve the quality of life of modem people who are deeply deprived of sentimental and emotional solitude in the technological civilization of the 21stcentury. The main purpose of this paper is to examine traditional Korean arts and crafts made using the intertwinement methodology through the context of strings, braids, straw crafts and knotting method. Then it will conduct through research on the different materials, forms, characteristics, usage and other key notions based on the currently preserved records and relics to contribute to the research on traditional textiles and provide the foundations to the development of the Korean culture and cultural products, reflecting the true sole and aesthetics of traditional Korean textile crafts.
