  • The purpose of this study is to obtain the dyed-fabrics of the elaborate patterns using the natural dye powders extracted from Galla Rhois, Sophorae Flos Immaturus, Clove, Sappan Wood, Madder, Log Wood and Japanese Green Alder. Specific informations on the separation and powder-making of each colorant were disclosed. Appropriate printing paste preparation and printing conditions including the viscosity and mordant concentration in the printing paste were investigated. The dyeability and colorfastness of the screen-printed silk fabrics with the colorant powders were discussed in terms of practical applicability. The deodorization and antimicrobial activities of the silk fabrics screen-printed with natural dyes were also assessed.

  • 일반적으로 빌드업 다층 인쇄회로기판은 에칭, 도금등의 습식공정에 의해 제작이 이루어지므로 많은 장비와 많은 시간이 필요하게 된다. 이러한 습식공정은 양산에는 적합하지만 개발단계에서는 그리 적합하지 않은 방법이다. 본 연구에서는 스크린 인쇄기술을 도입하여 빌드업 다층 인쇄회로기판을 제작하여 보았다. 절연성 재료로는 광경화성수지 또는 열경화성수지를 사용하였으며 전도성 재료로는 전도성 페이스트를 사용하였다. 층간의 전기적 연결을 담당하는 비아와 회로를 형성하기 위해 스크린 인쇄공정을 통해 전도성 페이스트를 인쇄 하였다. 이러한 방법을 통해 제품의 개발 단계에서 기존의 빌드업 다층 인쇄회로기판 제작 공정과 비교하여 좀더 효율적인 방법을 제시하였다.

  • $CaTiO_3$ thin films using silk screen printing technology were fabricated and their humidity sensitive characteristics have been investigated. The specimens were sintered at $1000^{\circ}C$, $1050^{\circ}C$, $1100^{\circ}C$ for 1 hour and the best humidity sensitivity was shown in the specimens sintered at $1000^{\circ}C$. The humidity sensitivity decreased with increasing measuring frequencies and was stable at different abient temperatures. Hysteresis of impedance variation with increasing and decreasing relative humidity were negligible.

  • The purpose of this paper is to establish the optimum fabricating condition of specimens using silk screen printing, and to develop humidity sensor which has good humidity sensing properties. The specimens are fabricated under the condition of 90[wt%] $SnO_2$-10[wt%] $TiO_2$, and their microstructure, crystalline structure, humidity sensing properties are examined. From the microstructure analyses, porosity is best at 700[$^{\circ}C$]. From the crystalline structure analyses, intensity of peak becomes strong according to increasing heat treatment temperature. From the humidity sensing properties analyses, an overall results of capacitance changes, linearity and hysteresis for the specimens is best at 600[$^{\circ}C$] and 700[$^{\circ}C$]. Capacitance of specimens increases according to decreasing measurement frequency, and to increasing relative humidity.

  • Dual band internal antennas were fabricated with Ag conducting paste of various preparation conditions and different print thickness by silk screen print. We have investigated microwave properties were compared Ag conducting paste antenna with copperplate antenna at 800 MHz and 1,800 MHz. Gain of Ag conducting paste antenna was improved when preparation conditions were the single size Ag particle, using dry type resin and high Ag containing percent. However, it was lower than that of copperplate antenna within $0.1\~2.0dBi$ at 800MHz. In addition, it was improved at 800MHz when thickness of Ag conducting paste was printed more than skin depth but it was held after critical print thickness. On the other hand, it was reached level of copperplate antenna at 1,800MHz.

  • Today, Fashion illustration has been diversified in its usage and respotlighted in the significance of its artistry by artists' interpretation and subjective perspectives. The purpose of this study is to find out theoretical reestablishment of this extended expression sphere and possible expression coverage of Fashion illustration. First, based on the Fashion illustration works revealing expressive features of Pop Art, this study reviews major considerations of Fashion illustration, i.e. assemblage, silk screen and new possible perspectives respectively. Therefore, based on the reviews, this study seeks to deduce pop art characteristics of expression technique found in Fashion illustration. Expression modes of Pop Art are represented broadly by assemblage, silk screen and new perspectives. Based on corresponding case analysis, this study could come to find out the following expressive features of pop art revealed in Fashion illustration: First, it is found that contemporary Fashion illustration pursues unbounded expressions and unprecedented styles owing to material variety. Second, it is found that contemporary Fashion illustration tries to adopt new and experimental techniques including computer program. Third, it is found that Fashion illustration characterized mainly by expressive features of Pop Art shows and pioneer a wide variety of application spheres including commercials(ads), newspaper or magazine illustration and cartoon ads simply beyond designer's creative drawing. Furthermore, it is expected that Pop Art's expressive features shown in Fashion illustration will evolve through a fusion with various experimental techniques, and keep having cultural and artistic influence in the future as well.

  • 본 연구는 디스플레이 모듈 접합 공정에 적용하기 위해 자외선 경화형 아크릴계 점착제(PSA)에 실리카 나노 입자를 함량별로 첨가하여 실크 스크린 인쇄성 평가를 실시하였고, 유변학적 성질이 인쇄성 및 점착력에 미치는 영향을 고찰하고자 하였다. 점착제(PSA) 중합을 위한 기본 처방으로 2-ethylhexyl acrylate(2-EHA)와 acrylic acid(AA)를 93:7 비율로 고정하고 butyl acylate(BA), 2-hydroxyethyl acrylate(2-HEA)를 첨가하였다. 추가로 나노 입자는 친수성 및 소수성을 가지는 AEROSIL R974 및 AEROSIL 200을 각각 사용하였다. 나노 입자 함량이 4 또는 7 phr 이상 사용함에 따라 G', ${\eta}^*$ 값이 급격히 증가하였으며, 친수성 나노 입자 AEROSIL 200을 7 phr 이상 첨가했을 때에는 스크린 인쇄 시 투과성이 저하되었다. 점착력은 나노 입자 함량이 증가할수록 감소되는 경향을 보였으며, 친수성인 AEROSIL 200의 경우 점착력이 더욱 저하됨을 알 수 있었다.

  • The costumes on a royal ceremony and the changes thereafter during the Korea Empire(1897-1910) have been elucidated through the review on the paintings on Queen Myong-Hun's 70th birthday celebration and the prospectus of the ceremony. Queen Myong-Hyn wore ceremonial gown in deep blue with 51 embroidered phoenix on it. The deep blue color the royal color in the Korea Empire replaced former red color. Go-jong wore violet crown and ceremonial suit in gold color. Twenty one kinds of court dance were offered during the celebration ceremony. Costumes therein appear to have an order according to the role ofdancers. most female dancers(in 17 performances not else-where specified) wore a rather common cos-tume-flower cap outer silk garent in green hand veils in 5 colors silk skirt in red) embroidered silk belt in red and shoes in green. In Sun-you-ak two female lead dancers were red hat decorated with tiger whisker deep blue outer garment wide red belt silk boots in black bow and arrows on back and a sword and a whip in hands. In Choonaang-jon a fe-male solo dancer wore a silk outer garment in yellow silk skirt in red green lorum embroidered silk belt in red wrist band of gold embroidered red silk and 5 color hand veils. In Yon-wha-dae two young girl dancers wore lotus-form crown green outer garment wide pants in red silk red silk skirt red silk belt hand veils in jade color and silk shoes in deep red. In Moo-go 4 female dancers each wore long waist coat in blue red white and warm light green in addition to the above-mentioned common costume. In Gumkee-moo 4 female dancers wore hatlike wool helmet outer garment with narrow sleeve long silk waist coat in blue combat belt in deep blue silk and dance swords in both hands. In Youk-wha-dae 6 female dancers each wore a long waist cost in red deep blue violet pale pink green and jade color. Green color of outer garment in the above-mentioned common costume of female dancers appears intersting. Although the color was shown as yellow in the screen paintings actually it was green as evidenced by the prospectus of the celeebration ceremony.

  • 회화적 기법의 제작 방식은 애니메이션에서 종종 활용된다. 그 중 판화의 제작 방식은 애니메이션 제작에 활용 되고 있으며 실크스크린과 목판화는 자주 활용되어 기법 연구의 사례도 많으나 동판화를 활용한 애니메이션의 제작 또는 연구의 사례는 빈약한 실정이다. 따라서 본 연구는 동판화 애니메이션 제작의 교과서적 표본이 되고있는 폴란드의 영화감독이자 표현주의 메조틴트 동판화 애니메이션 감독 피오트르 듀말라(Piotr Dumala)의 작품 사례를 통해 동판화 애니메이션의 제작 기법을 소개 하고자 한다. 메조틴트 동판화만이 표현해 낼 수 있는 독특한 질감과 운동감, 깊이감, 조형적 특징을 분석한다. 애니메이션 작가들에게 동판화 기법을 에칭과 인그레이빙으로 나누어소개함으로써 회화적 애니메이션 제작 기법의 폭을 한 단계 확장시킬 수 있다.
