  • 본 연구는 목기 수공업을 통해서 전통 수공업의 현황과 육성정책 및 방향을 모색하였다. 인류는 석기문화를 형성하였고 아울러 목기문화도 병용하였다. 목기문화는 보존이 불가능하여 곧 칠기 출현의 계기가 되었다. 옻칠은 방부, 방수의 역할을 함으로써 해서 오랫동안 보존이 가능하게 되었다. 목기는 삼국시대, 고려, 이조시대를 통하여 상용으로 널리 쓰였으나, 1900년대 이후 스테인 그릇, 플라스틱 그릇 등 저가의 상품이 등장하면서 쇠퇴의 길을 걸었으나 전통산업으로서 목기수공업을 고부가가치의 산업으로 육성할 수 있는 정책과 방향이 모색되어야 한다.

  • Every year fish skin, bone and intestines are discarded as processing waste material. The use of fish processing waste material is more economical and environmental-friendly. The leather-like material was produced using shark intestine. Physical charactistics such as tensile strength, elongation, tongue tearing strength, and bursting strength of the leather-like material were measured, and compared with those of a commercial leather product. The values of tensile strength, elongation, tongue tearing strength, and bursting strength of the leather-like material were $3.3kg/mm^2$, $53\%$, 13.0kg/mm and $18kg/cm^2$, respectively. Elongation $(l09\%)$ of the leather-like material coated with lacquer was higher than that of a commercial leather material, and the other factors were similar. The tensile strength and tongue tearing strength of the leather-like material was higher than those of shoes leather, but bursting strength was lower. These results suggested a potential value to use the leather-like material from shark intestines as a substitute for commercial leathers.

  • For mass production of electronic devices, the processing of the printing roll is one of the most important key technologies for printed electronics technology. A roll of printing process, the gravure printing that is used to print the electronic device is most often used. The indirect laser processing has been used in order to produce printing roll for gravure printing. It consists of the following processing that is coating of photo polymer or black lacquer on the surface of printing roll, pattering using a laser beam and etching process. In this study, we have carried out study on the coating and etching for $25{\mu}m$ line width on the printing roll. To do this goals, a $4{\mu}m$ coating thickness and 20% average coating thickness of the coating homogeneity of variance is performed. The factors to determine the thickness and homogeneity are a viscosity of coating solution, the liquid injection, the number of injection, feed rate, rotational speed, and the like. After the laser patterning, a line width of $25{\mu}m$ or less was confirmed to be processed through etching and the chromium plating process.

  • Ribes fasciculatum (Saxifragaceae) has been widely used as a traditional medicine for the treatment of cough, antidote, cold, lacquer poison, and sore throat. In the present study, we evaluated the anti-nociceptive effects of ethyl acetate fraction of Ribes fasciculatum (ERF) in mice. Test results of tail-immersion test and hot plate test revealed that the ERF had strong anti-nociceptive activities on thermal nociception in a dose dependent manner, indicating ERF's anti-nociception on the central pain. Moreover, the acetic acid-induced chemical nociception was also significantly reduced by ERF treatment. This result shows that ERF may also work on the peripheral pain. We further performed formalin test to confirm ERF's anti-nociceptive properties and found that pain responses were significantly decreased by ERF treatment. Interestingly, in the combination test with naloxone, the analgesic activity of ERF was not changed, indicating that the opioid receptor was not involved in the ERF-mediated anti-nociception. These results indicate that ERF might be possibly used as a painkiller for the treatment of nociceptive pains.

  • Excised cotyledons and embryo axises of zygotic embryos of Rhus vemicifera were cultured on Murashige and Skoog(MS) medium with various concentrations of 2,4-D. About 3-5% of explants produced callus. Embryogenic callus was preferentially induced from basal parts of embryo axis of zygotic embryos seeds when they were cultured without removal of seed coats. Somatic embryos were developed from embryogenic callus in growth regulator-free medium after 2-3 subcultures on medium with 1.0mg/L 2,4-D and these embryos were matured to cotyledonary stage. Plantlets with well-developed shoots and roots from embryos were obtained on $\frac{1}{4}$MS medium with GA$_{3}$. After acclimatization of plantlets on artificial soil, they were exposed to soil pots.

  • This study is about watching the changes in Modern and Contemporary ages, through Traditional Ottchil Painting analyzed the formative characteristics presented on 23 pieces of Najeon Master Bong-Ryong Kim. He restored and reproduced the Ottchil Painting Technique by making Najeon ware (lacquer ware inlaid with the mother-of-pearl) on the Korean Modern and Contemporary period. The formative characteristics of his Ottchil Painting Technique are as follows. He used a lot of the Myochilchaehoi Technique as the technique of expression, along with the Najeon Yanggam Technique mixed with Myochilchaehoi Technique. The frame material of Ottchil Painting Ware is handcrafted wood. And in the painting foundation, red is presented more than black. The colors of painting and the pattern drawn on the foundation of Ottchil painting are mainly bright red, blue, yellow, black, and white (five-color). The main pattern used is the dragon, and the subordinate patterns are clouds and Arabesque. Also, the main pattern is solo, and the subordinate pattern is mostly an arrangement combination of radiation symmetry. This style of art was most commonly used for painting fruit trays. As stated above, Bong-Ryong Kim presented various and masterful aesthetic quality based on sincere and exquisite Najeon ware production skills.

  • The purposes of this study were to identify the material manipulation techniques for paper garments and their characteristics. Reference books or articles were reviewed and catalogues from paper garments exhibition or show, brochures from Paper Museums, and internet sites of paper fashion designers were selected for analysis. Paper has much similarity with natural cellulose textiles in appearances and contents but has much distinct differences in their physical characteristics such as strength, durability, washability, and resilience, and could be treated as one category of textiles. Paper garments were developed with practicality and functionality for the poor and Buddist monks at first but progressed into more aesthetics later for the rich. Paper garments could be divided into 4 categories of garments made of paper, paper thread fabric or knit, modified paper with wanter, and beaten bark of mulburry bush. Paper can be manipulated by coloring & cutting, bonding, or quilting and bonding or quilting can reenforce the strength of paper but cannot increase flexibility. Paper manipulated by weaving or knitting has very similar physical properties as cotton or linen and ideal for summer textiles. Paper can be manipulated with water to make a paper paste and bodice can be moulded with paper paste or Joomchied. Also we can express beautiful patterns on the surface of paper by washouting. Konnyaku paste or lacquer can be used to make paper garments to be waterproof.

  • It is thought as more important for us to understand foreign countrie's culture in the modern society. because the world is becoming closer day by day thiough the develepment of communication and mass-media. Cross-cultural study could play a role to give an opportunity for people to understand foreign countrie’s culture easily.In this respect, this study was planned to find out similarity and difference between Danish and Korean folk tables made and used before the 20th century during the 18th-l9th century as a part of the comparative study of folk furniture between the two countries. It would be very interesting if we could find something valuable between Danish and Korean folk furniture. because they are located very far away each other geographically with less cultural communication before.There were more differences than similarity between the folk tables of the two countries and major findings were as followings : Firstly, there were many kinds of space-saving tables in Denmark. whereas only a few kinds of tables which could be removed easily after their usage were found in KoreaSecondly, Banish folk tables were more emphasized on the function rather than decoration. Whereas Korean folk tables were smaller lower and more decorative than Danish ones to fit their life-style of sitting on the floor.Thirdly, many Danish folk tables were made of bare wood. while Korean ones were finished by transparent lacquer or vegetable oil. Stone tops if tables were rare in both countries. Lastly. there were common factors in the design of legs of folk tables in both countries. It was interesting that animal legs such as deg tiger cat. lion, and eagle were used for design motif of the table legs. But trestle leg, cross leg and gate leg were not found in Korean folk tables. As a conclusion, throughout this study, it became obvious that life-style was one of the most important factor influencing on the design of furniture.

  • The ethanol extract of Rhus verniciflua Stokes (RVS), the Korean Lacquer tree, was subsequentely isolated and fractioned into two portions using distilled water (SED) and 99% ethanol (SEE) as elution buffers through silica gel column (4x28 em, 22 $\AA$. 28~200 mesh). To know the antioxidative effect of the RVS extracts, primary hepatocytes were exposed to hydroxyl radical generated by 20 mU/$m\ell$ glucose oxidase with SED or SEE for 4 hr. The addition of 100$\mu\textrm{g}$/$m\ell$ SED in culture medium showed good protection from glucose oxidase (GO)-mediated cytotoxicity of hepatocytes, showing approximately equivalent to control. When the hepatocytes were incubated with 100 $\mu\textrm{g}$/$m\ell$ SED or SEE only for 4 hr. the activities of cell-associated superoxide dismutase (SOD) and catalase were elevated up to 1.22 fold and 1.4 fold, respectively, compared to control. Further increase, 1.88fold in SOD activity or 1.64fold in catalase activity, was also observed when the hepatocytes were incubated with 100 units/$m\ell$ of commercial SOD or catalase for 4 hr. Moreover. the glucose oxidase-mediated cytotoxicity in cultured hepatocytes was generally reduced upon addition of lysate obtained from SED or SEE-stimulated hepatocytes in a dose-dependent manner. From these results, we suggest that, in cultured hepatocytes, RVS ethanol extract can efficiently reduce cytotoxicity induced by glucose oxidase and may increase the activity of cell-associated SOD and/or catalase, thereby preventing and/or scavenging superoxides and hydroxyl radicals in this experiment.
