Recently, it has been reported that chemical hair coloring can cause allergic reactions, the toxicity issue of chemical hair color was issued. Therefore, there is an increasing interest in the hair coloration technique using non-toxic and bio-compatible hair color gotten from natural resource. In this study, the possibility using fermented Indigo as natural hair coloring agent was investigated. Bleached hair samples were dyed using Indigo, and the effect of dyeing frequency, the physical change after dyeing, color, surface and cross-section characteristics, and tensile property were also studied. In addition, the protection property of cationic detergent finishing on damaged hair samples were also studied. The following conclusions are made; 1. While bleached hair samples with low value showed the negligible effect of repeated dyeing, bleached hair samples with high value showed the good effect of repeated dyeing. 2. Hair sample dyed with Indigo showed a high light-fastness, however, tensile strength and elongation showed very low values (high damage on hair sample). 3. Cationic detergent finishing did not affect on the colorfastness because of decoloration after dyeing, however, it increased the smoothness of hair sample, and therefore, can use as protectant of damaged hair. 4. Hair scale was damaged after dyeing. It seemed that the alkali, potassium carbonate, increased pH of dyeing bath to 11, as a result, the hair was swollen, weaken, and dissolved on the prolonged dyeing time. Dyed hair sample became stiff and fine. 5. The color difference was 4.62 (a high fastness value) in the test of sunlight exposure, shampoo, cationic detergent finishing, and acid perspiration fastness.

인간은 자연현상으로 발생되는 소리와 인공적으로 발생되는 소리 속에 살고 있다. 인간의 생물학적 행동을 유발시키는 것 또한 소리이다. 감각기관 즉, 청각으로만 인식할 수 있는 소리의 또 다른 표현은 예술의 형식을 통해서 가능하다. 음악과 미술은 같은 감정을 표현하는 예술호서 표현방법만 다를 뿐 둘 모두 우뇌(右惱, dextrocerebral)를 사용하고 직관력이 필요하다는 공통점을 가지고 있다. 이런 관계로 지금까지 음과 시각예술을 접목하려는 시도가 계속되어 왔으며, 주관적인 해석의 예술적 작품에서 컴퓨터를 이용한 작품에 이르기까지 음의 시각화 실험은 계속 시도되어지고 있다. 본 연구는 음의 시각적 표현 중 디자인 저 표현의 본질과 특성을 규명하며, 기존의 학문적 특성과 연구 범주, 최근의 주요 동향에 대한 고찰을 바탕으로 향후 음의 시각표현의 방법론을 정리하고 재해석하여 이의 디자인에 대한 연구 방향을 제시함을 목적으로 한다. 본 연구를 토대로 향후 한국음악 특히 사물놀이가 가지고있는 음색적 특색 및 각 악기의 상징을 이용한 시각적 표현의 가능성을 모색하는 후속연구를 통해 음의 새로운 시각표현의 기능성을 모색코자 한다.

결정질 실리콘 태양전지의 전면전극은 수광면적을 극대화하면서도 전기적 저항을 최소화하기 위하여 미세하면서도 높은 종횡비로 형성되어야 한다. 기존의 전면전극 형성공정은 스크린 인쇄가 이용되었으나, 스크린 제판 개구부의 선폭보다 인쇄된 전극의 선폭이 1.3~2.2 배 넓게 형성되는 문제 때문에 $40{\mu}m$ 급 미만의 미세전극을 형성하기 위해서는 스크린 제판의 개구부는 $30{\mu}m$ 이하여야 한다. 그러나, 개구부가 미세화될수록 인쇄압력의 증가, 실버 페이스트 전이 불량률 상승 및 메쉬 마크로 인한 전극의 전기적 저항 상승과 같은 문제들이 발생한다. 본 연구에서는 스크린 인쇄를 대체하기 위한 차세대 인쇄방식으로서 스크류 펌프방식의 디스펜싱 인쇄를 소개하고, 기존 인쇄방식과 차별화되는 점들에 대해 논의하도록 한다.

This study understands rockers of today and supplies basic data of design and manufacture studying pattern change of rockers arisen in West, there is the purpose. Also, this study is investigated by dividing theoretical background of rockers, 7 kinds of American traditional rockers and European rockers from 18th century to opening part of 20th century and contemporary rockers since 20th century. The theoretical background and the style of 2 rockers (Windsor rocker, Boston rocker) were investigated to study the stylistic changes of rockers. Originally a rocker was invented by a European farmer around 1700. It developed to a household which equip practicality and comfortablness in the United States than Europe. Early rockers in a primal form appeared in the 1740s in the United States. American early rockers connected skate to established chair bridge. Rockers are deep connection with family's emotion. Rockers can provide playing functions for children and medically treating functions for adults. Windsor Rockers developed by attaching skate is mammy bench and according to shape of back form bow or hoop-back rocker, birdcage rocker, comb-back rocker. Windsor Rockers formed peculiar American tradition of craftsman furniture through structure that have a unique back of a chair and round seat. Boston Rockers were the first chairs made by mass production method. They show a particular shape with S-curve style seat and rectangular crest at the upper part of the back. Often Crests were decorated by stenciled pattern with curled leaves such as rosettes and scrolled designs.

The styles of contemporary landscape design have diversified since the emergence of Postmodernism in landscape architecture. The diversification was mostly influenced by contemporary fine arts and architecture. This study examines the pluralistic development of Postmodern landscape design through the investigation of the influences from those sister arts. In this point of view, the main approaches of Postmodern landscape design are thought to be classified into three categories;'the formal abstract approach', 'the figurative approach' and 'the new picturesque approach'. The first category of the formal abstract approach was formulated with the concepts and vocabulary of Minimal Art and Installation Art. Its representative icons such as 'point grids' and 'stripes', and the main concepts such as the sense of 'flahess', 'expansion' and 'materiality' are mostly thought to be originated from these art forms. The second category of the figurative approach is characterised by the concepts and vocabulary of Pop Art and New Image Paintings. Its representative icons such as 'map' or 'figurative forms' and main concepts like the sense of 'reality', 'context' and 'symbolism' are mostly thought to be originated from these art forms. The third category of the new picturesque approach was formulated with the concepts and vocabulary of Land Art and Late Deconstructive Architecture. Its representative icons such as 'hybrid', 'layer' and 'fold', and the main concepts such as the sense of 'complexity', 'continuity' and 'reversibility' are thought to be originated from these art forms. The research shows that the main stream of contemporary landscape design seems to be gradually moving toward the second and third approach above, in step with the cultural orientation and the dynamism of contemporary urban life. Therefore, the study focused especially on the new picturesque approach which would be in greater need for coping with the hybrid culture today.

These series articles were written in order to understand rockers of today and to provide basic data of their designs and manufacture studying pattern changes in the West. In the first article of the series reports we already described the theoretical background of rockers and the Windsor and the Boston style among the American classic rockers from the eighteenth to the twentieth century. This article contained the characteristics of the styles of the Shaker rocker, the Wicker rocker, and the Platform rocker. The three periods associated with furnituremaking in the Shaker sect are; the Primitive Era, which lasted from 1790 to 1820; the Classical Era, from 1820 to 1860; and the Final Phase, from 1860 to 1935. The important skills the Shaker needed to make the Shaker rocker are woodturning joinery, seat braid weaving and steam bending for the slats. The Wicker rocker continues to be extremely popular furniture style as the wicker proved equally effective for translating the ornate vine-like motifs popular among Art Nouveau proponents. The Wicker rockers were developed for child's, gentleman's and lady's, and it represents the most diverse forms among the above mentioned styles. However the rocker skates were often clumsy and took up too much room, preventing the chair from being shoved close to the wall and out of the way. These problems were overcome by the Platform rocker. The most important innovation was the technical development of a stationary base, which allowed the chair to rock noiselessly, without skating along the floor. The Modernism of the modern furnitures in America and Europe were affected by the characteristics of the Shaker rocker, the Wicker rocker, and the Platform rocker.
