As the digital environment gets ubiquitous, domestic and international research and development on smart clothing is being conducted actively these days. However, most research is being carried out with its center on upper garment. So research on lower garment is insufficient even though it affects wearer's activity and comfort to a great extent when digital devices are attached or wearers moves their body. Therefore, the type of clothes this research proposes is men's formal pants which have an electrically-vibrating wearable device. These are smart pants which are helpful in easing muscle pain with their massaging effect in daily life. For this purpose, this research intends to develop patterns considering the body shapes and movements of wearers and suggest a tentative structure plan for smart pants where a vibration device is attached, which is mainly composed of vibrating motor, controller, and switch, and considered their bulks, numbers, attaching places.

This study focuses on apparel production and consumption trends in major Asian economies in order to understand a paradigm change in the Asian fashion industry. A comparison of trade among ASEAN, NICs, and developed countries shows the changes that have occurred in terms of production and consumption of fashion products before and after 2000 in Korea, Hong Kong, and China. The flow of imports and exports in the apparel industry was analyzed using UN trade statistics data. The results found a change of industry structures in Asian NICs and ASEAN countries. Garment production bases have moved to lower cost regions like China and ASEAN; in addition, NICs sent a part of their export business in the fashion industry to ASEAN countries. The Asian fashion industry has transformed from a production base for developed countries into a consumption market with the emergence of newly industrializing economies.

의류산업은 대표적인 노동집약적인 산업 중 하나로 의류 제조의 기본 공정인 봉제 작업은 인력에 대한 의존도가 매우 높다. 의류 생산비용은 라인의 효율성에서 큰 영향을 받는데, 생산비용의 절감을 위해서는 생산 속도를 조절하여 라인의 균형 유지하는 것이 중요하다. 그러나, 현재 의류 생산라인에서 활용되고 있는 인력에 의한 생산 실적 집계 방식은 이를 위한 부수적인 인력의 소요 등으로 인한 추가 비용이 소요되어 중소기업들이 직접 적용하기 쉽지 않다. 완제품의 인력에 대한 의존도는 집계 시간의 추가 소요와 인적 오류가 크게 잠재되어 생산비용의 증가와 함께 효율성의 저하를 초래할 수 있다. 본 논문에서는 에너지 소비 데이터를 수집하고 이를 CNN (Convolutional Neural Network) 기법을 적용하여 분석함으로써 재봉 작업을 통하여 생산한 제품의 수량을 추적하고 자동으로 집계할 수 있는 봉제 작업 생산 추적 시스템을 제안한다. 개발된 시스템을 통하여 2종의 재봉 작업을 테스트 한 결과, 최대 98.6 %의 정확도를 보이며 재봉 작업을 감지할 수 있었다. 개발도상국에서 의류봉제산업은 매우 중요한 산업이나, 위에 언급한 문제들을 해결하기 위하여 고가의 첨단기술을 적용하는 등 많은 자본을 투입하는 것은 크게 제한된다. 적정 기술을 적용한 본 기술은 이러한 개발도상국의 의류산업에 큰 도움을 줄 수 있을 것으로 판단된다.

The purpose of this study is to determine how the people's view on afterlife affects their perception about shrouds. As part of analytical research, the survey was carried out to take a look at the basic thoughts that average persons have on afterlife. This paper also performed the survey on what the shroud reminds the subjects of. Specifically, the questionnaire survey was conducted to see what the people think the necessity and appropriate cost of shroud and see if they have any plan to get it provided in detail. Data from this work were statistically processed and empirically analyzed. Findings of this study can be summarized as follows. As to the funeral methods, the subjects in this work preferred cremation to burial. It was found that they recognized shrouds as necessary, but they did not have a thought in a serious manner that the suit for the dead would affect the repose of the dead and guide his or her soul to the heaven. Those respondents did not have any immediate plan to purchase shrouds, either. However, they considered the price of shroud as most important when they might come to choose the garment. With regard to the quality, it turned out that they preferred the domestic shrouds whose material are natural to those from foreign country. Also, they opted for such a kind whose shape is not so different from that of casuals they would usually wear and whose color is same to the main material of the original garment. The common material preferred most by the subjects was a hemp. The subjects' view of afterlife was not greatly related not only to how much they recognized shrouds as necessary but also to their preference for materials and patterns. On top of this, their unique taste for particular types of shroud was found to be significantly dependent on whether their view of afterlife is positive or negative, whether they firmly believe in afterlife, whether they take the absolute predestination and whether they accept the prayer-effect relationship in terms of psychology.

This research studied how to develop tight upper sportswear from 3D scan data considering fabric stretch property. Subjects were five Korean men of average figure in their 20's. Scanning was done for ten postures via vitus smart/pro(Techmath LTD). Analyzing from 3D scan data, more than 70% of the upper body surface showed surface change rate under 20%. It was shoulder and under arm side part that showed most noticeable body surface change when moving. A parametric model with convex surface was generated and flattened onto the plane, resulting 2D pattern. The error rate occurring in the process of 3D to 2D conversion was 0.2% for outline and 0.13% for area, respectively. Thirteen kinds of stretchable fabrics in the market were collected for this study. Stretch property was in the range of 16.0~58.2% for wale direction; 23.1~78.4% for course. Based on wear trial test, four fabrics were chosen for making the 1st experimental garment and finally one fabric was chosen for the 2nd one, which was developed applying 4 kinds of crosswise reduction rate on 2D pattern: 0, 5, 10, and 15%. Through wear trial test and garment pressure measurement, experimental garment applied with 10% pattern reduction rate was evaluated as most comfortable and considerable.

The purpose of this study was to examine of the flower patterned fabrics used for the Shrouds during 15~18th century in Chosun Dynasty. The Shrouds at that time could be classified by the garments for the dead(殮襲衣) and the utensils used in religious services(殮襲諸具). And we looked into the types and the compounding methods of the flower pattern used for the utensils used in religious services(殮襲諸具) as well as the Shrouds accounting to the uses. Results of this study are as follows. 1) The flower patterned fabrics weaved as the uses of the garments for the dead(殮襲衣), item by item, were divided into the upper garment, the lower garment and men's Po(coat). 2) Seeing Jeogori, mixed various flower patterned fabrics, among the upper garment, there were focused on the various good meanings such as longevity, integrity and prosperity etc. 3) The flower patterns in men's Po(coat) were used a lot in Jangui and Dahnryoung. Cheollik, Dappo, Jeonbok, etc made of the flower patterned fabrics, were of small number but we can feel an aesthetic sense of men at that time. 4) The flower patterned fabrics weaved the lower garments, were used much more in the skirts than in the trousers, for reasons of the wrapping a dead body. 5) Seeing the flower pattern used the utensils used in religious services(殮襲諸具), the pattern of Lotus and Arabesque, among the types of flower pattern, had a majority.

This study was designed to testify the possibility and devise the method to manipulate the 3D body scan data to produce rounded-belt pattern adaptable to hip-type variation of women in their 20's. The results of this research were as follows : Firstly, based on drop-value distribution of hip and waist girth, 151 subjects were classified into three hip-types; Type 1 (15.23%) was 'cylinder type', showing lowest drop-value, Type 2 (69.54%) was 'average type' and Type3 (15.23%) was 'hourglass type' showing highest drop-value. Secondly, using CAD program, design lines for round shape belt were set on the surface of 3D scan data of representative subject of each type. And divided 3D surfaces were flattened onto the plane by the internal tools of CAD program. The measure, 'lifting value of round belt pattern', implying the level of curve ratio of pattern was higher in back than front. This result might be linked to the fact that the hip part is more protruded than the abdomen part. And the measures also showed highest values in Type 3(hourglass type) and lowest in Type 1(cylinder type), meaning that the pattern of Type 3 showed more rounded shape than that of Type 1. This finding implied that round belt for body type having high drop-value should be shaped more curved. Thirdly, difference ratios of outline length and area between 3D curves(body surface) and 2D plane(pattern) were 4.5% and 1.3%, respectively. This result demonstrated and solidified the feasibility of designing digital garment pattern from 3D body scan data.

The increase in the need for a 24 hour monitoring of biological signals has been accompanied by an increasing interest in wearable systems that can register ECG at any time and place. ECG-monitoring clothing is a wearable system that records heart function continuously, but there have been difficulties in making accurate measurements due to motion artifacts. Although various factors may cause noise in measurements due to motion, the variations in the body surface and clothing during movements that cause eventual the shifting and displacement of the electrodes is particularly noteworthy. Therefore, this study used biomedical body mapping and a motion-capture system to measure and analyze the changes in the body surface and garment during movements. It was deduced that the area where the friction and separation between the garment and skin is the lowest would be the appropriate location to place the ECG electrodes. For this study, 5 male and 5 female in their 20s were selected as subjects, and through their selected body movements, the changes in the garment and skin were analyzed using the motion-capture system. As a result, the area below the chest circumference and the area below the shoulder blades were proposed as the optimal location of electrode for ECG monitoring.

This study is a design study related to the application of 3D printer technology for garment printing. Knitting, which used to be a home industry in the early days, originally comes from hand-knitting. This evolved with various personal devices as a small job for the self-sufficiency of early European housewives. In addition, since the Industrial Revolution, mechanical production entered the mass production mass supply system, and various apparel products were provided to consumers in accordance with mass standardized dimensions. This is similar to the development process in Korea. In addition, it has formed a considerable market with the situation that it can produce and supply apparel products at low labor costs of first-generation Namdaemun and Dongdaemun merchants. As the production shifted to the Southeast Asian region due to the increase in labor costs in the domestically developed social situation, the production of garment products in Korea is now almost 5%. As a result, apparel-related production facilities and related companies are constantly moving to other countries to move production facilities sensitively due to rising labor costs. Recently, smart factory automation has been planned to explore new possibilities. In addition, in recent years, with the evolved appearance of consumers, the appropriate supply of the right amount of production has appeared, and the 3D printer applied to personal garment output has attracted considerable interest in the customized market. Therefore, in order to become a new hope and a small addition to various clothing workers, this study conducted related research on the following 3D printers for clothing output and attempted to proceed with a new design.
