  • The bacteria, which were capable of producing ${\beta}-1$, 3-glucanase inducibly by utilizing cell wall of Aspergillus fumigatus as a sole carbon source, were isolated from soil in the campus of Kyungpook National University. Among them, the strain which produced the enzyme excellently was selected and identified to be Pseudomonas stutzeri KF 13 by morphological, cultural and physiological examination. The optimal conditions for the enzyme production from Pseudomonas stutzeri KF 13 were investigated. the enzyme production was reached maximum state shen the broth cultured for 72hr at $30^{\circ}C$. And the enzyme showed the highest activity in the medium containing 3.5% cell wall as an inducer, 15% yeast autolysate as a nitrogen source and 0.05% $MnSO_4$ at pH 7.5.

  • The optimal cultural conditions for production of the bluish purple prgment by the cultivation of Streptomyces californicus KS-89 were determined with various substrates. The carbon and nitrogen sources on the production of pigment indicated that soluble strarch and glycerol as carbon sources and sodium glutamate sodium nitrate as nitrogen sources given a mzimum yield of the pigment at 3$0^{\circ}C$ for 7 days. The addition of ferrous sulfate was essential. The highest production of pigment was observed with cultivation in a medium containing 2.0% soluble starch 1% glycerol 0.5% sodium glutamate 0.05% sodim nitrate 0.001% L-proline 0.025% K2HPO4 0.005% MgSO4 .7H2O, 0.04% FeSO4.7H2O, 0.001% thiamine.HCl and pH7.0.

  • Animal glue has been used as a binder in Dancheong since the Joseon dynasty. Binders play an important role in determining the physical characteristics of a painting layer. The analysis of binders can be used to identify the materials and techniques used in traditional Dancheong. Binders can be investigated using physicochemical component analyses methods such as gas chromatography/mass spectrometry, pyrolysis-gas chromatography/mass spectrometry, and fourier transform infrared spectroscopy, but the detection characteristics vary depending on the degradation properties of the pigment and binder. Therefore, cross-validation using a combination of physicochemical analysis and enzyme immunoassay is used to increase the reliability of the results. In this study, we present an enzyme-linked immunosorbent assay (ELISA) as an example of an enzyme immunoassay as a method for analyzing animal glue, a traditional binder used in Korea. The applicability of ELISA was tested using commercial animal glue, in addition to animal glue produced using a variety of extraction conditions. The animal glue was analyzed in a Noerok-additionally coated-replica sample to evaluate the possibility of analyzing the animal glue in a paint layer mixed with pigment. Based on the results, we performed an assay on the use of animal glue in the Dancheong sample of the temples of the Joseon dynasty, that are estimated to have been built in the 17th century.

  • To examine the method for preservation of papers, 9 kinds of papers were purchased and pretreated for 6 months with various artificial conditions which were controlled as 3 temperature classes($20^{\circ}C$, $80^{\circ}C$, $-20^{\circ}C$&$20^{\circ}C$) and 4 humidity classes(40%, 60%, 80%, 100%).Whiteness, acidity and folding endurance were measured to examine the state of papers pretreated under each condition. From the resultexamining the state, all the papers were best condition at low temperature($20^{\circ}C$) and low humidity(40%) and damaged at high temperature($80^{\circ}C$) and high humidity(100%).The values of whiteness, acidity, and folding endurance were measure din relation with deterioration of papers. According to damage of papers caused by the chemical agent, papers became to be acidic, increased color difference and reduced the force of folding endurance. The effect of change of temperature($-20^{\circ}C$&$20^{\circ}C$) on degradation of papers was not well acquired. Because the period of investigation was not long enough to acquire the data. So the more studies are needed to find the cause of damage of papers.

  • 문화산업은 국가의 고유의 가치관과 생활양식 등 문화적 특징으로 만들어진 것으로서 장식성, 실용성의 특성을 지니며 대중들이 이용하는 생활필수용품, 기호용품 등을 총칭하는 것으로 규정하고 있다. 공예문화산업은 지역, 환경 등의 특성을 기반으로 하여 전통예술의 문화적 특징을 가진 상품을 생산하는 공예산업으로, 공예문화상품에 내재된 전통적, 문화적 요소를 이용하여 생산하여 소비하는 일련의 과정으로 문화산업을 의미한다. 공예문화산업의 각 부분에서 나타난 문제점과, 해결방안을 중심으로 중요성을 재조명하여 공예문화산업의 발전을 개발하는 문제적인 부분을 해결할 것이라고 생각한다. 본 연구에서는 공예문화상품에 대한 대중성과 매출현황을 조사하여, 국내의 공예문화산업의 실태를 연구하고 발전방안에 대해 알아보고자 한다.

  • 이 연구에서는 암석의 함수율과 이방성에 따른 초음파속도 변화를 분석하여 석조문화유산에 적합한 측정방법을 설정하였다. 암석의 함수율과 포화도는 건조 초기에 급격한 변화를 보이다가 변화율이 서서히 줄어드는 지수함수 형태를 나타냈다. 그러나 초음파속도 및 변화율은 10시간의 자연건조 이후 거의 일정한 수치를 유지하였다. 따라서 수분에 포화된 석조문화유산은 기상환경 및 함수조건을 고려하여 약 10시간의 자연건조 후에 초음파 측정을 수행해야 한다. 이방성지수는 화강암과 석회암에서 가장 높은 수치를 보였으며, 간접전달방법이 직접전달방법에 비해 이방성에 둔감한 측정법으로 나타났다. 그러나 간접전달방법에 의한 이방성은 모든 암석에 미약하게나마 존재하므로 다양한 방향성을 고려한 초음파 측정이 요구된다. 이 연구결과는 석조문화유산의 암석학적 특성에 적합한 맞춤형 비파괴진단과 신뢰도 높은 정밀 평가에 크게 기여할 것으로 사료된다.

  • Felt, is one of the Korean traditional woolen fabrics, that is thermally excellent and durable, so it has been widely used for various living goods from the ancient time to the modern society. Felt makes various changes in colors and shapes, does not change easily even after a long-term use, and is easy to clean. In this study, the origin and history of felt were researched. Also, different kinds and shapes of felt and the currently used manufacturing technique, and how the Korean traditional pattern-applied cultural products were developed using felt were examined as well. The method of this study were as follows. First, felt manufacturing techniques used after investigating the precedent studies, books, records and literatures of museums, the existing relics of felt were examined. Second, the conditions of the traditional pattern-applied cultural products were found out through the precedent studies after examination of kinds and symbols of the Korean traditional patterns. Third, patterns that were applied to cultural products were selected and designed with new patterns. Fourth, the past techniques were conducted with the following three methods by referring to the range of cultural products manufacturing; )color felt made with one color, pattern felt, and pattern-embroidered felt. Fifth, the following products combined with decoration and practical application by applying felt techniques were used. This study was aiming at the development of practical cultural products made with the traditional wool, felt, which can receive a good response from all age groups. It is allegedly required to develop various cultural products through studies and the rediscovery of the national traditional materials. In the future, it is necessary to study in such a way that diversification and differentiation are made through approaches and attempts with various techniques.

  • 본 논문에서는 문화산업이 국가경쟁력의 새로운 척도로 부각되는 가운데 국가단위에서 지역도시단위로 옮아가고 있고 지역 특성화 방안으로 문화산업 즉, 엔터테인먼트산업에 대한 지역 및 주민의 요구가 크고 다양하게 증대되고 있다. 문화산업의 도시별 차이점을 고찰함으로서 대 . 중소도시별 상관관계와 문화산업의 접근방법에 따른 이해와 이용의 차이를 분석하였고 대도시와 중소도시에 따른 변화나 문화정책도 연구목적으로 하였다. 연구결과에서 첫째, 문화가 변화함에 따라 문화산업이 변화하는 것으로 나타났다. 둘째, 사회적 여건에 따라 도시별 차이점을 발견할 수 있었는데 대도시에선 대중문화 부상이 영향을 미치는 요인으로 나타났으며 중소도시에서는 대중문화 부상이 영향을 미치고 있으나 문화생활화도 중요시됨을 도출 할 수 있었다. 셋째, 경제적인 여건에 따라 도시별 차이점을 발견할 수 있었는데 대도시에선 문화유통체계다양화와 문화상품화, 문화클러스터화가 고루 영향을 미치는 요인으로 나타났으며 중소도시에서는 문화유통체계다양화와 문화상품화가 영향을 미치고 있으나 문화 클러스터화에 대해 영향을 못 미치는 것으로 나타났다.
