이충무공 종가 관련 고문서는 덕수이씨 후손가에서 보관해오던 것으로 다양한 종류의 문서가 전해지고 있다. 연구대상인 고신교지, 증직교지, 교첩, 교서, 유서, 홍패, 칙명의 국왕문서 7종은 그 제작시기가 명확하고 고문서의 원형을 그대로 유지하고 있어 보존처리 과정에서 과학적 조사 분석을 통해 당시 고문서 제작에 사용되었던 종이 특성을 확인하고 문헌 기록의 내용과 실제 문화재를 일부 비교해 볼 수 있었다. 표면 섬유 형태에서 '외발뜨기(흘림뜨기)' 초지방식으로 제작된 형태 특성이 확인되었으며, 밀도 측정과 종이 표면 분석에서는 대부분의 고문서에서 도침 가공된 종이특성이 관찰되었다. 섬유 분석에서는 모두 닥섬유를 원료로 제작하였으며, 주로 성숙한 닥나무 인피섬유가 사용된 것으로 확인되었다.

Preventive conservation is one of most important issues in the field of conservation for paper-records. Many researchers have been studied environmental factors such as effects of humidity, temperature, biological attack and air pollutants. Air pollutants strongly associated with oxidative and hydrolytic degradation of cellulose. It is important to control air pollutants in storage environment to improve stabilities of conservation environment. Four paper samples have been analyzed for their accelerated aging characteristics by air pollutants, sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide. Physical and optical properties and weight molar masses(Mw) showed that interactions between air pollutants and paper sample. Nitrogen dioxide, ozone caused severe damage to cellulose in paper by hydrolytic and oxidative decompositions during aging.

Paper cultural asset show various deterioration characteristics and behaviors according to the environmental conditions during the storage. The understanding of the paper itself and its conservation knowledge is thus prerequisite to preserve paper cultural assets and pass them to descendants in a good condition. The Annals of Joseon Dynasty is one of the most important our written cultural assets (National treasure No.151) and it is registered as a UNESCO Memory of the World. The Annals of Joseon Dynasty is composed of 1707 volumes and 1,187 books that were written on the official history of 472 years(AD 1392-1863) from King Taejo to King Chuljong (25 generations). Among them, beewax-treated Annals show severe damages due to the deterioration of wax materials such as breaking, hardening, darkening, discoloring and whitening. Urgent measures should be taken to preserve the Annals and prevent further deterioration. Therefore, a systematic and scientific approach on the conservation and restoration of the Annals of Joseon Dynasty is definitely necessary. So it can be used an example to show how much the preservation science can conserve the paper cultural assets. In this respect, this study focuses on analyzing paper properties and deterioration behaviors of the Annals of King Sejong, the most damaged one, using non-destructive micro analysis techniques.

We preformed many treatments to preserve Kim-gu's relics (Baekbum-ilgi and the clothes stained with blood). The first we performed re-paper mount of binding area of baekbumilgi, and fumigated all relics to sterilize microorganism. Then all relics were sealed with biaxially oriented polyvinyalcohol film(BO-PVA film) and $N_2$ gas filled up in the BO-PVA film bags. We investigated the paper condition of Baekbum-ilgi, its brightnees was 25-35%, water content was 9.4%, and acidity was pH 4.3. These results indicated that the paper was very weak. On the other hand, We analyzed his blood type and genetic type with the solidified blood of the clothes. In result, his blood type was AB and were classified 6 genetic types such that HUMTH01 was 7-9 type, HumTPOX was 9-11 type, HumCSF1PO was 12-13 type, HumF13A01 was 4-4type, HumFESFPS was 12-12, and HumvWA was 18-18 type.

Since the 1970's, UNESCO and ICOMOS have adopted or emphasized on the principles of historic preservation. One of them is what to require a repair should not be repaired beyond the limits of the features and techniques which had been adopted in those days of establishment. On the premise, this paper is to examine the materials and technique of wall plaster work in the government building constructions in the Joseon dynasty. The result of this examination shall come up with a basic conformity in the case of repairing the building established in the late of Joseon dynasty. This paper is carried out for the proper repair and restoration of architectural cultural properties. Construction reports and other documents in those days are examined for the study. Following conclusions have been reached through the study. The materials and technique which applied to wall plaster work in those days were quite different from the present. The technique that was used to wall plaster of government buildings in those days was not a lime wall plaster, but sand coat one. The kinds of material for setting of the sand coat wall plaster had been revised with the change of the times or constructions. The main kinds of material were composed of sand, white clay, paper fiber, and cereal starch. However, the present materials were composed of sand, white clay. Therefore, the present materials and technique which applied to wall plaster work for the repair and restoration of architectural cultural properties have to be revised and corrected.

한지로 된 고서적의 가수분해가 Trichoderma viride로부터 분리한 endoglucanase I, exoglucanase II와 endo-exo혼합효소 (I：I, weight ratio)에 의하여 수행되었다. Endoglucanase I, exoglucanase II와 endo-exo혼합효소에 의한 가수분해 최적pH는 각각 4.5, 5.5, 5.0으로 나타났다. 이들 결과들은 지류문화재의 열화가 산성조건에서 셀룰라아제의 활성을 증가시켜 촉진될 수 있음을 보여준다. 또한 이들 효소들에 의한 분해에 있어서 최적 분해온도는 모두 5$0^{\circ}C$를 보여주었다. 고서적의 재생펄프를 이들 효소로 처리했을 때 수율(yield)과 물리적 강도(physical strength)를 살펴보면, 수율은 이들 효소의 농도 증가와 함께 감소함을 보여 주었다. 특히 endo-exo혼합효소로 처리했을 때 가장 낮은 값을 보여 주었다. 이는 endo성분과 exo성분의 협동작용(synergistic action)에 의한 것으로 생각할 수 있다. 물리적 강도는 exo II로 처리했을 경우 농도 증가에 따라 향상됨을 보여 주었으며, exoglucanase II와 endo-exo혼합효소로 처리했을 경우는 농도에 따라 감소함을 보여 주었다. 이들 결과들은 고서적의 분해(열화)가 endoclucanase에 의한 것임을 보여 준다. 즉 지류문화재의 물리적 강도를 저하시키는 주요 성분 효소는 endoglucanase이며 지류문화재의 효과적인 보존을 위해서는 endoglucanase성분의 활성을 억제시킬 필요가 있다.

This paper is intended to describe the idiosyncratic aspects of the verb way construction in English, clarifying the productivity property of this construction and to elucidate the claim that this construction displays the properties of language-general, not a language-particular by comparing the behaviors from Dutch. And this paper will argue against the lexical approach and explain the drastic mismatches in syntax and semantics responsible for the constructional properties as one type of directional motion constructions by proposing a constructional analysis in HPSG.

This study was carried out to investigate the characteristics of starch paste which was used for the conservation of paper properties. Three kinds of commercial corn starch and five kinds of fermented wheat starch were examined on the contents of amylose and amylopectin, shapes of particles, and viscosity and pH of paste. And adhesive strength on the drying, accelerated aging, and wetting treatments were measured. The contents of amylopectin of oxidized corn starch were higher those of cationic corn starch, unmodified corn starch, and fermented wheat flour. In case of fermented wheat flour, increasing of a fermentation period was resulted in increasing of amylopectin contents. The particle shapes of commercial corn starch showed with a uniform polygon, but fermented wheat flour showed with a mixture of small and large oval types. The viscosity of oxidized corn starch were very lower those of cationic corn starch and unmodified corn starch. And increasing of a fermentation period of wheat flour was resulted in increasing of viscosity. The pH of commercial corn starch were 3.6-7.5 and fermented wheat flour were 3.6-5.2. Through the examination on the nature and adhesive strength of starch paste, the oxidized corn starch 60 cps which is the name of products and wheat flour which had fermented for 5 years were considered that most suitable for conservation of paper properties.

고문헌이나 예술품에 대한 저작자의 진위 여부 판정은 문화재 관리 측면이나 소장자의 재산가치 평가를 위해 상당히 중요한 측면을 가지고 있다. 이를 위해 문화재청의 전문가들이 진위 판정을 행하고 있는데 이는 경제적 비용이 상당히 소요된다. 따라서 이를 컴퓨터에 의해자동으로 행하는 시스템의 개발에 대한 사회적 욕구가 증대하고 있는 실정이다. 본 논문에서는 이를 위해 작품의 경계 형태 분석에 의해 저작자의 진위 여부를 판정하는 시스템을 개발하고자 한El. 이는 진품 판정에서 생각할수 있는 여러 1띠 특징 벡터 중 우선적으로 중요한 특징 벡터하고 생각되기 때문이며 차후여러 가지 특징 벡터를 취합하여 저작자의 진위 판정을 종합적으로 행하는 시스템을 개발하고자 한다. 최종적으로 본 논문의 유용성을 실험에 의해 입증코자 한다.

사적 259호 선원사지(禪源寺地) 4차 발굴에서 출토된 지류(紙類) 유물들을 분석을 하고 이를 통해 보존상황에 맞는 보존처리방법을 연구하였다. 지류(紙類) 유물이 펼쳐볼 수 없는 상황에서 가장 중요한 보존처리 과정은 유물의 분리이고, 분리는 지류(紙類) 유물의 상태에 따라 분리방법을 달리하여 연구하였다. 건조한 상태의 유물 중에서 경화정도가 약한 것은 Gore-Tex chamber를 제작하여 분리하고, 경화정도가 강한 것은 여과수를 사용하여 분리하였다. 젖은 상태의 유물은 진공동결건조방법을 통해서 분리하였다. 지류유물의 분석은 재료의 특징을 알기 위한 종이의 조사, 전자현미경과 SEM을 통한 섬유의 분석, X선 형광분석법(XRF)에 의한 글씨 재료를 분석하였다. 유물의 제작 연대를 추정하기 위하여 가속기 질량 분석기에 의한 탄소연대측정을 하였다. 분석과 보존 처리 과정을 통하여 출토 유물의 분류가 되었고, 유물의 분류는 원형을 상실한 유물들의 원형보존을 가능하게 하였다. 본 논문에서는 가장 열악한 상태의 지류유물의 보존처리 방법의 적용을 제시해 보았고, 탄소연대측정을 통하여 자료도 제시할 수 있었다.
