Conservation treatment of modern cultural heritage rickshaw from National Museum of Korean Contemporary History were carried out. The Rickshaw is divided into three parts which are chair part, sun-block cover part, wheels part. Treatment was referred to analysis results of P-XRF, species identification, FT-IR and microscope observation on Rickshaw. Outer films of rickshaw were chipped off. Therefore, conservation and restoration treatment were carried out in the damaged area. Degradation in armrest, saddle and backside of chair may cause serious problem. Therefore, the reinforcement were carried out with similar materials. Dry and wet cleaning were performed in sun-block cover to remove white stain and corrosion contaminant. Furthermore, reinforcement and restoration were performed in damaged area. Rickshaw from National Museum of Korean Contemporary History was made with various materials. This research result expects to be a great example of conservation treatment for modern cultural heritage which is made of various materials and to be used as useful data for conservation and restoration in modern cultural heritage.

The magazine (Bulletin) of "Seikou" was made by conservation engineers to exchange information about the survey and repair work of historic buildings in Japan before World War II. This magazine has 26 volumes in total, and was published periodically four times a year from April 1937 to December 1943. Publisher is Nindokai that is supposed to the forerunner of Bunkenkyo (the Japanese Association for Conservation of Architectural Monuments). Only 3 or 4 organizations except personal possession have it now. And it has a limit to use the contents of the article as a general historical material. So, it was rare that experts and researcher used to the "Seikou". However, this study focuses on the articles of the Korean historic building, which is sometimes appeared in it, although there are few. The purpose of this paper is to clarify the fact-finding of the conservation for the Korean historic building in Japanese colonial period by analyzing the articles in historical records of "Seikou".

The Unhyungung Water Container in the possession of the Seoul Museum of History in Korea is consisted of a calcareous marble developed laminated bedding and numerous argillaceous veinlets. This monument should need to conservation treatment because of black discoloration and seriously numerous cracks. Vertical and horizontal cracks in the monument are developed following stratification and argillaceous veinlets that are relatively low coherence between the rock materials. We have proved that the material inducing discoloration on the surface is carbon which is formed by deposited organic matters. As the result of the ultrasonic measurements, although highly surface weathering degree, the physical properties of the Unhyungung Water Container is confirmed slightly weathered state. The depths of cracks in the monument are calculated at maximum 60mm in some cracks completely penetrating into the wall and at minimum 9mm in the other crack. The cracks, developed following veinlet, are revealed that there penetrate from an outer wall to an inside wall for the monument. And most depths of cracks, developed following stratification, are calculated 20 to 30mm. This result will offer a significant data for conservation of the Unhyungung Water Container.

This article is an introduction to : ICCROM PAPERCONSERVATION COURSE 1993" which I participated in, from July 28th 1993 to September 24th. The program was divided into two major sections. The first part deal with scienctific principles of paper conservation, covering structure and composition of paper and related materials, causes of deterioration and guidelines for preservation. It include chemistry for paper conservators and the history and technology of papermaking. Second part of the course emphasize practical conservation ; participants actually work together with specialists. Two weeks are dedicated to the Western approach to paper conservation. A selection of recent conservation treatments are discussed methodologically, demonstrated and performed. The same amount of time are devorted to a seminar on the conservation of fareastern paper objects. The aim is to exporse participants to different approrches and methodologies in paper consevation, to compare and discuss various tendencies and to learn lessons from other experiences that are applicable to one's own work.

This study investigates the crystallinity distribution of ancient silk. Owing to the inherent multi-hierarchical structure of silk protein and the complicated structural changes that occur due to various burial environments, it is challenging but worthwhile to study ancient silk ageing behavior, which is based on the fact that ageing begins with a single fiber and then spreads to a whole fabric. Crystallinity was one of the most effective indicators found to reveal the ageing status of silk. Therefore, a synchrotron radiation-based X-ray diffraction(SR-XRD) method was employed to study the crystallinity distribution of single fibers of ancient silk unearthed from seven archaeological sites in China from historical periods including the warring states, Han dynasty, Song dynasty, and Ming dynasty. In comparison, the conventional X-ray diffraction method, which uses large amounts of samples, was also performed to determine the integral crystallinity of ancient silk. Thermal stability experiments by thermogravimetry(TG) as well as morphology observations by scanning electron microscopy(SEM) and optical microscopy(OM) all confirmed the deterioration of ancient silk. Moreover, the ageing mechanism of ancient silk was proposed with the assistance of an artificial ageing study. The results confirmed the effectiveness of SR-XRD as an ageing indicator, revealing the crystallinity distribution. This research could provide motivation to determine the deterioration status of ancient silk, and would also aid in explaining the fragility of ancient silk due to ageing.

The purpose of this study was to analyze the correlation between conservation activities and the development of tourism in the modern period in the Korean peninsula. The main building of Jangansa Temple, located in Mt. Geumgang, was repaired in the 1930s. During the repairs, the Japanese General-Government actively engaged in the development of Mt. Geumgang and raised funds for the operation of the Korean Peninsula through tourism revenue. The repair work was carried out under the influence of the Mt. Geumgang development project. And its influence is revealed by reviewing official documents recording repair work. This study tried to clarify the relationship between development and repair work through official documents.

This paper is to review the conclusions of the Athens conference that has so far contributed to the conservation world. It is normally called the conclusions of the Athens conference as the Athens charter. But the conclusions of the Athens are not as same as the Athens Charter regarding the contents. The former had more valuable contents than the latter regarding historic monuments. And the report of the Athens conference including 56 articles and 500 pages with 55 photos was published in 1933 by the International Museums Office. But little attention has been given to the report of the Athens conference. Therefore the point I want to make is to review to the report in order to understand the agenda of the conference and to examine the Anastylosis in Acropolis. In conclusion, these agendas and the articles in the report show us that the conference was sort of milestone with some advanced modern philosophical and technical concepts about conservation and restoration of historic monuments. Also when the term of anastylosis turns to reconstruction in archaeological sites, we are going to face with the problems of authenticity.
