As archives, photograph is the evident records of historical facts and experiences. Thus, it is worth preserving. Unlike other documents silver halide photographic films and prints are quite sensitive to environmental factors such as light, temperature and humidity, which demands careful treatment in preservation. This study was carried out to select popular photographic films and papers on the market, to examine their photographic speeds (or sensitivities) and to compare and analyze their preservative features after keeping them some time in a weather-o-meter. Consequently, B/W materials were superior to color ones in preservation. And films were better than papers in the same manner. But we were not able to observe remarkable differences among material's manufacturers.

This study attempted to determine the effect of storage temperature(5$^{\circ}C$ and 25$^{\circ}C$) and time(1, 24, 48 and 72 hours) on the sensory and textural properties of mungbean starch gels. The color value, syneresis, texture and sensory properties of mungbean starch gels were measured. As the storage time increased, the lightness(L) and whiteness(W) values of mungbean starch gel increased. This trend was more apparent at the storage temperature of 5$^{\circ}C$. The syneresis of gels also increased as the storage time increased and the storage temperature was lower. As the storage time increased, the hardness of the gel increased whereas the adhesiveness and cohesiveness of the gel decreased. These results showed that mungbean starch gel lost its typical viscoelasticity during storage. This trend was also more apparent at the storage temperature of 5$^{\circ}C$. Sensory characteristics of the gel were well correlated with the mechanical characteristics. Overall quality of the gel decreased markedly at the 2nd day storage at 5$^{\circ}C$ and at the 3rd day storage at 25$^{\circ}C$.

자료의 보존에 있어서 종이의 열화로 인해 자료의 분석, 열화메커니즘의 해석, 종이의 보존이란 측면 하에서의 관심이 서서히 집중되고 있는 실정이며, 그 중요성도 크게 대두되고 있는 실정이다. 산성지를 중성화하는 화학적시스템, 즉, 탈산성화처리는 알카리계금속(Ca, Mg, Zn, Na)과 유기용매, 수용성용매를 이용하여 이들 약품을 종이내에 침투시켜 중성화(pH 6-8) 함으로써 종이의 주성분인 cellulose를 보다 안정화시키는 방법으로 산을 중화하여 보존성을 향상시킬 수 있는 것이다. 즉, 탈산처리란 화학적으로 종이속에 생기는 산 또는 산을 발생하는 물질을 알칼리물질로 중화하는 것이다. 또한 중화후 알칼리 물질이 종이에 잔류하면 장래에 내부적으로 발생하는 산이나 외부(대기중의 오염물질 등) 로부터 침입하는 산도 중화하여 보존성을 향상시킬 수가 있다. 따라서, 본 연구는 산성초지법에 의해 제조된 용지들의 열화특성과 알카리 토금속을 처리한 후에 알카리도를 상승시킨 용지의 열화특성을 물리·화학적 변화를 통하여 종이의 보존성을 비교 검토·규명함으로써 문(도)서의 보존체계를 마련하고자 하며, 보존과 관련된 기초자료를 얻고자 실시하였다.

The purpose of this study is to suggest the characteristics of a cooperative storage facility for academic libraries in Korea. For this facility, discussed are how to select a site, build physical facilities, recruit participating organizations, prepare for selection criteria and ownership of resources, confirm service policies, and implement a integrated library management and access system. It is emphasized that a cooperative storage facility for academic libraries in Korea should ensure the optimum use of space on campus, preserve "the last copy" which is not frequently used, but still has scholarly values, and extend the effective and efficient resource sharing among participating libraries.

Landscape has two side, ecological structure and visual characteristics. And Landscape evaluation should be implemented from this viewpoint. In this study, landscape of the Moodeungsan natural park was evaluated based on ecological and visual characteristics, and the results was compared with the existing zoning. And it was recognized that the areas having high preserbability are located in the nature environmental zone. For the purpose of natural park management planning, in this study, rezoning method of natural park based on landscape evaluation is proposed.

Natural preservative agents are generally made of antibiotic substances that are extracted from plants. They are used mainly to keep in an original good state food, natural cosmetic goods and medicines which are likely to get rotten. The purpose of this study is to investigate whether natural preservative agents can be applied to fabrics for the preservation of textile cultural properties. For the purpose, this researcher experimented with a certain natural preservative agent which was developed to preserve natural cosmetic goods. The study found that when treated with the foresaid natural preservative agent whose ratio to water was 1%, fabrics showed little changes in color and tensile strength, almost neutral pH, high antibiosis and anti-fungus and high resistance to Bacillus cereus that is much detrimental to silk fabrics. As a part of the study, a preliminary test on the possibility of using natural preservative agents to preserve textile cultural properties, found that when kept covered up with the 1% natural preservative agent-treated fabrics for 72 hours, excavated textile relics showed a dramatic decrease in microbial growth.

The purpose of metal artifacts conservation is recovering the original state of objects and preventing it from further corrosion. Four different consolidants are selected that are widely used for bronze objects conservation. This study found out the characteristics of thin film by various experiments and analysis for the bronze plates coated using each solutions. After a series of analysis, resin B and V showed good coating properties. However, the evaluation point suited to this purpose are adhesive strength, stability against yellowing and corrosion resistance. Therefore, resin B of four different consolidants could expect to get the most suitable consolidation effect for consolidation purpose.

The purpose of this study is to describe and analyze the characteristics of seven major cooperative storage facilities for academic libraries in the U.S.A, Australia, and Scotland in order to provide a frame of reference for such a facility in Korea. Analyzed are unique characteristics of these storage facilities in relation to their physical facilities, uses and services for collections, participating organizations, ownership of resources, and integrated library management and access systems. Some objectives of operations and physical environments are shared by these storage facilities, and have some implications for the development of cooperative storage facilities in Korea.

The purpose of this study is to provide the methods of preservation for paper, microfilm, digital media. First of all, for acidic papers produced in 19~20 centuries, this study evaluates and analyses deterioration and factors causing deterioration. For book, also, environmental condition for preservation, and a preservation mechanism through acid-free procedure were suggested. Second for microfilm, it emphasized physical and chemical properties, oxidised substance during developing film, materials related to preservation. Third, for digital storages, storage conditions and needs, such as life-cycle and capacity were introduced.

The Stone Seated Buddha Triad and Stone Standing Buddha in Bijung-ri are state-designated heritage (treasure) statues having the Buddha style of the Goryeo dynasty from the 6th century. Conservation scientific investigations were conducted to understand the preservation status of these stone Buddha statues and to establish a conservation plan. The Stone Seated Buddha Triad and Stone Standing Buddha are composed of fine-medium grained biotite granite, which is considered to be of the same origin owing to their low magnetic susceptibility distribution of less than 0.2 (×10^-3 SI unit) and similar mineral characteristics. The Stone Seated Buddha Triad has highly homogenous mineral composition and particle size, whole-rock magnetic susceptibility, and geochemical characteristics very similar to those of the nearby outcrop. It was confirmed that a combination of physical, chemical, and biological factors affects the Stone Buddha statues. In particular, both the Stone Seated Buddha Triad and Stone Standing Buddha tend to be chipped off from the front and cracked and scaled from the back. The Stone Standing Buddha located outdoors experiences granularity decomposition and black algae formation, which accelerate the weathering under unfavorable conservation environments. The result of non-destructive physical property diagnosis using ultrasonic velocity showed that both the Stone Seated Buddha Triad and Stone Standing Buddha have been completely weathered (CW), indicating very poor physical properties.
