Recently towel cloth has a good prospect as sports wear and out fashion wear. So we will discuss correlational effects between towel cloth quality and it's physical properties. In order to investigate the effect of pile length on the stiffness and absorption of the towel cloth, some experiments have been carried out, and then analyzed by the correlation coefficient.

Tuban area in East Java, Indonesia, has a role as one of international ancient trading ports since 11th century. For that role, Tuban has accepted many foreign cultures that are brought by other nations, such as Tionghoa and Gujarat. The improvement of Tuban that involves international relationship clearly influences the forms of tradition and culture that is shown in Tuban nowadays. It is believed that from those tradition and cultures owned by people of Tuban, producing cloth is one of the oldest tradition maintained by the people. Those clothes, as one of traditional products, have unique identity that differ them to other regions. It is because the uniqueness of people's knowledge about cosmology concept, and skill owned by the people that passes through generations. This research explains the condition of traditional cloth tradition of Tuban society with fundamental ground data and explains elements that intervenes the tradition, and forms resulted from it.

This study was undertaken to develop the artificially soiled cloth using clay and dyed oleic acid as model soil and to evaluating the detergency by determination of K/S value and chemical analysis. The results obtained were as follows : 1. Correlation were determined between the K/S value and chemical analysis data for the detergency of developed model soil at various conditions and it was found that model soil could be extensively used for the washing examination. 2. The surface reflectance of soiled cloth with clay-oleic acid mixture was measured two wave length band that was converted K/S values and the amount of two components was individually calculated. Positive correlation were found between detergency that obtained from chemical anlysis and K/S values. Therefore, proposed method of soiled cloth with clay-oleic acid mixed soiles could be extensively used for detergency experiment. 3. The attached state of soil of on the artificially soiled cloth which was observed under a scanning electronic microscope showed a different pattern by the sort of soil. And the difference of attached state of soil had great influence upon the detergency. 4. The composition of clay was changed and formated of noncrystalinity was vanished by calcined at $800^{\circ}C$. Because of a noncrystalline of clay, artificially soiled cloth could be prepared more uniformly but the detergency was decreased.

효과적인 스마트의류에 기반한 유-헬스케어 시스템 구축을 위해서는 스마트의류에 적합한 하드웨어 및 소프트웨어 모듈의 설계가 필요하다. 그리고 스마트의류에서 센싱된 생체신호를 서버로 전달하기 위해서는 센싱신호의 수집 및 처리를 위한 게이트웨이 스마트폰 프로그램이 필요하다. 이를 위해서는 게이트웨이 프로그램 모듈을 잘 설계하고 기술하여 나중에 구현시에 어려움이 없도록 하여야 한다. 또한 의료진이 스마트폰에서 보내지는 생체신호를 수시로 모니터링 하지 않더라도 이들 신호의 변화값이 규칙/사실에 기반한 전문가시스템 구축으로 자동으로 진단되어 사용자에게 알려준다면 아주 유용한 유-헬스케어 시스템이 되리라 본다. 따라서 본 논문에서는 이러한 기능들을 갖춘 스마트의류 기반의 유-헬스케어 시스템 하드웨어 및 소프트웨어 모듈의 설계 방법을 제시함으로써 본 설계 방법이 유-헬스케어 상용화 시스템 제작에 매우 유용하게 활용될 수 있음을 보여준다.

This study is to research the changing trends in the trading goods and the cause of the change in the early Chosun dynasty and to find out the influence that the export goods had on the Chosun society. This research demonstrated the costume culture of the early Chosun was affected by the trading trends. The export items of Chosun showed differences in chronological order. They changed from hemp cloth to cotton cloth. The cause of such change in the export items was due to the change in the amount of demand and supply, to products of Chosun. and to social factors. Looking at the amount and items of the export goods to Japan, the amount was huge and the number of trade was a lot. There were several influences that the exporting cotton cloth to Japan had on Chosun's costume culture. First, the export caused the growth of cotton industry through the reinforcement policy. Next, it made the amount of national deposit of cotton cloth exhausted as a result of the increase in the amount of the exporting cotton. It also made worse the dual distribution structure of cotton cloth and the leaning toward bad cotton cloth. And in consequence of the connection between rich merchants and politicians, these social phenomena became worse and worse. And these facts demonstrate that the costume culture of the early Chosun dynasty was affected by the trade between Chosun and Japan. Therefore, to better understand the costume culture of the early Chosun dynasty, I propose to consider the consequences resulted from the trade with Japan.

Purpose: Through studying the expert's and non-experts panel responses to the questions regarding the attributes of chemical-biological protection cloth quality in terms of the levels of customer demand and technical factors has been studied. We are applied to a QFD matrix with find out the relationship between the selective removal efficiency of chemical-biological cloth and the guidelines of technical approach. Methods: We fabricated several composite of ion-exchange resins with selectively permeable performance designed to facilities water vapor transport and selective adsorption of the harmful gases. With these materials, we characterized on the selectively permeable performance to identify ion-exchange resin with chemical-biological protective cloth. Results: Results showed that ion exchange materials possessed performance with selectively efficiencies as NH3, SOx, NOx and HCl gas. The selective adsorption amount of ammonia and hydrogen gases were $90-80{\mu}g/g$ with TRILITE SCR-BH sulfonated ion exchange resin. The PP non-woven/ion exchange resin adsorbent materials possessed performance with water vapor permeability were 1,100-1,350 g/m2/day, it's was two times high value compare with activated carbon. With these materials, we characterized selectively removal efficiency to identify new ion-exchange material with chemical-biological protective capability. Conclusion: This study shows that a QFD aids in deciding with of the adsorption parameters to optimized with chemical-biological protection cloth manufacturing.

직물을 모델링 할 때 사각 메쉬 기반의 파티클 시스템이 이미 제시된 바 있다. 그러나 일반적으로 삼각 메쉬를 사용하여 직물을 표현하므로 삼각 메쉬 기반의 직물 모델링이 필요하다. 삼각 메쉬를 이용한 직물 모델링은 보통 물질이 연속적이라고 가정하는 유한 요소법적인 방식을 사용한다. 본 논문은 파티클 시스템의 장점인 모델의 간단함, 구현의 용이성 등을 삼각 메쉬상에서도 살리기 위해 삼각 메쉬 기반의 파티클 시스템을 제안한다. 직물의 움직임은 메쉬 꼭지점들이 삼각 메쉬의 에지들을 통해 서로 상호작용하도록 모델링한다. 꼭지점들의 상호작용은 두 개의 구조, 즉 에지 연결 구조와 대각선 연결 구조를 이용하여 정의하고, 상호작용을 할 때 생성되는 변형 에너지는 탄성이론을 적용하여 모델링하였다. 사각 메쉬에 적용되었던 파티클 시스템의 장점 을 삼각 메쉬에 구현한 것이 본 논문의 공헌이다.

최근 높은 관심을 모으고 있는 모바일 증강현실 게임은 몰입감을 높이기 위한 접근 방법으로 손꼽히고 있다. 모바일 디바이스의 카메라를 이용하여 대상 물체를 인식하고 게임 캐릭터가 등장하도록 하는 기존 증강현실 기반의 게임에서는 대부분이 터치 기반의 인터랙션만을 사용하고 있다. 본 논문에서는 게임의 몰입도를 높이기 위하여 증강현실 타겟 이미지를 움직임으로써 게임 속 변형 객체를 직관적으로 조작하는 기법을 제안한다. 제안 방법에서는 타겟 이미지들 사이의 거리와 방향을 계산하고, 이에 따라 변형객체에 주어지는 외부력(external force)의 크기를 조정함으로써, 직관적 방법으로 변형 객체의 움직임을 조작할 수 있도록 하였다. 본 논문에서는 게임 콘텐츠에서 자연스러운 객체 표현을 위하여 많이 사용되고 있는 변형 직물(cloth) 모델에 초점을 맞추었고, 바람(wind)과 강체(rigid object)로 표현되는 게임 객체들과 상호작용하는 자연스러운 직물의 움직임을 표현하였다. 실험에서는 유니티 에셋 스토어에서 판매하는 기존 유료 직물 모델의 적용 결과와의 비교를 통하여 제안 기법이 보다 현실감 있는 직물의 움직임을 표현하고 있는 것을 보였다.

The effects of nonionic surfactants on detergency and water wetting/retention properties of soiled cotton cloths were reported. Two different soiled cloths were used. soiled cotton cloth 1 was made in the lab. with carbon black, tripalmitin, n-dodecane & palmitic acid on Korea Apparel Testing & Research Institute(KATRI) cotton testcloth and soiled cotton cloth 2(EMPA 101) was purchased from Testfabrics, Inc., USA. The following nonionic surfactants; l.e., Span 20, Tween 20, 40, 60, 80, 21, 61, 81, 65, & 85, were used in the study. The water retention ratio(W/H) values of soiled cotton cloths were decreased, whereas the water contact angle values of soiled cloth were not changed markedly compared with those of unsoiled testcloths. The wetting and water retention of soiled cotton cloth 1 was improved with addition of nonoinic surfactants. The surfactants which have more hydrophilic characterictics or unsaturated hydrophobe tails were effective in improving wetting and water retention properties of soiled cotton cloth 1. The water contact angle values of soiled cotton cloths were extremely low with Span 20, presumably due to the high adsorption density or the surfactant. The detergency of soiled cloths were low in Span 20 and high in Tween 20, 40, 60 & 80 0.1g/dl surfactant solutions. Nonionic surfactants having higher ethylene oxide contents resulted in better detergency. In the range studied, the wetting and water retention of soiled cotton cloths did not show any particular relation to the detergency, whereas the surfactant characteristics, especially HLB values, influenced the detergency of soiled cotton cloths.
