Stone cultural properties(pagoda, Buddhist statue etc.) is moved in original place for many reasons and restored after taking to pieces for structural safety. With the movement and restoration after taking to pieces, the cast iron is used for the sake of a fixation and horizontality. The stone cultural properties are spoiled the beauty and accelerated the weathering because of the corrosion product of cast iron. So we need to substitute for the improved property in all aspects. We are executed the corrosion test and inquired the property of material on the usable material for the shim of stone cultural properties. That is the Cast iron, Stainless steel, Titanium and Fiber Reinforced Plastics. In the result of the physical property and strength, the Stainless steel and Titanium was superior to the Cast iron. And the Stainless steel and Titanium was slower than the Cast iron in the corrosion velocity for the acid, salt and rain. If the shim is substitute the Stainless steel or Titanium for the Cast iron, the stone cultural properties are able to reduce the pollution of stone cultural properties by corrosion product and should not happen in the matter of stone pagoda.

In this study, we investigated the petrographic characteristics and physical property of the Rock-carved Seated Buddha at Bugmireugam hermitage of Daeheungsa temple in Haenam. The Buddha Statue was carved on micrographic granite, and the rock was composed of the fine quartz encircled by orthoclase. The results of diagnosis for deterioration evaluation have shown a highly damage rate of black contaminants (8.4%) and crack index (6.6). The ultrasonic velocity have detected SW (slightly weathered) grade of weathering coefficient (mean 0.18). Various weathering factor on the surface of the Buddha Statue was affected by precious shelter, and physical property with ultrasonic was directly influenced by the structural characteristics and fissure of host rock.

Paper is easily damaged by physical and chemical deterioration under several factors. Damaged paper cultural heritage is usually restored by Lining. A traditional method of Lining is attaching the lining paper behind the original paper cultural heritage using starch and water. It supports the weakened quality of paper. In Japan, paper cultural heritage is restored with "Washi" which is made from mixture of Paper mulberry and Japanese cedar. In the west, the lining paper made from Paper mulberry, which has extraordinary excellent conservativeness, is usually used as a restoration material for paper. But Japanese Washi has dominated the demand for restoration materials as the most preferred restoration paper, and most kinds of paper made from Paper mullbery have been called as 'Japanese paper'. Result showed that the strength of the Korean lining papers was generally higher than that of the Japanese ones. As a result from measuring the rate of dimensional change after water-immersion and drying, sample B of the Korean lining papers and sample E of the Japanese lining papers showed the highest stability.

The concepts of authenticity and integrity are very important standards to be satisfied in the conservation and utilization of Scenic Site (名勝), literally meaning the places of scenic beauty, as a public heritage. These concepts, which are frequently used in the conservation and utilization of the World Heritage inscribed by UNESCO, can be applied to all kinds of heritages. Recently, it has been widely recognized that the concepts of authenticity and integrity are not separable but interconnected. Accordingly, the maintenance of authenticity in Scenic Site should include not only the physical preservation but also the succession of historical tradition of enjoyment. The integrity in Scenic Site refers to the physical and social conditions under which authenticity can be satisfactorily protected. The aim of this study is to reconstruct the traditional ways of enjoying historical and cultural Scenic Site with emphasis on the Yeongnam Region and make a critical examination of cultural property protection areas that have been designated. Then, this study aims to find the ways to utilize Scenic Site to secure the standards of authenticity and integrity. As a result it was discovered that cultural property protection areas are not designated well enough to satisfy the standards of authenticity and integrity. Considering the fact that cultural property protection areas are the minimal institutional systems to maintain the original value of Scenic Site, it is necessary to pay more careful attention to the ways of securing the authenticity and integrity in Scenic Site.

This study started from my concern over maintenance and renewal of existing buildings and other seriously damaged Modern Architecture under the urban development. Above all, we must face up to reality of an increasing need of renovation of old buildings that are in its physical, social, and economical decrepitude. Currently, 25% of total buildings come under renovation period within 20 years, which means that we do not have enough time to decide the destiny of old buildings. In the city, there has been endless controversy over conversation and development. Recently the Cultural property Registration System made it possible a positive usage of non-designated cultural property with historical value. This very useful system renewed our perception on Modern Architecture as cultural property and also triggered peoples' interest in recreating new value beyond economical one. So we really need a balanced view that can bring into both growth of contemporary city and renewal use of Modern Architecture. Here, in this study I tried to solve that problem with Conversion Design and define what a realistic design way for them is. To get more reasonable result, I chose a factor analysis for 20 conversion projects in Japanese Modern Architecture. Conversion Design is a proper way to restore the identity of old buildings and the most effective way to sustainable use of Modern Architecture.

This study tries to find out the properties of soft ind hard white wares of white wares from Dudong-ri in a scientific way, especially by meant of physical chemical analysis, microstructural observation. As a result, In the physical analysis, soft white wares are found to have higher absorption and porosity. In the composition analysis, the chemical property, of body and glaze, shows that the composition of them varies with excavation areas. However, no clear difference is identified between the soft and hard white wares which are from the ssme kiln. The microstructural observation visibly shows the difference of hard and soft white wares which it verified in the physical property Minerals with round pores and vitrified feldspar are observed in the body of hard white wares, but no vitrified particles but widely distributed pores with long and sharp irregular shapes are found in the body of soft white wares. In conclusion, the hard and soft white wares from Dudong-ri kiln are mainly influenced by physical property and microstructural rather than chemical composition and firing atmospheres. However, more and various comparative studies are needed since the resources with various physical properties vary among kilns of each production area.

A great numbers of cultural properties destroyed though attack by insect pests and microorganisms. Biodeterioration damage is particularly serious in this country because many cultural propertiese are made of organic materials. Recently, there are various countermeasures of biodeterioration or alternative methods are reported, such as Gamma Radiation, Micro-wave Irridation, Freezing, Inert Atmosphere (Oxygen-less atmosphere), and Environmental Control. However its practical application are limited and some difficulties for treatment of large objects. Fumigation is one of the most useful and effective methods of control biodeterioration because it gives less damage of cultural properties but rapidly eradicate infesting organisms at one action. This paper evaluated selected fumigants and fumigation methods with emphasis on the following paragraph:1) Effectiveness of selected fumigants on insects and microbes involved inbiodeterioration.2) Physical and chemical characters of selected fumigants.3) Less toxic new alternative fumigant and its mixtures.4) Inert atmosphere (Oxygen-less atmosphere)5) Methods of fumigation : Sealed fumigation, Covered fumigation and Vacuum fumigation (Reduced-pressure fumigation)

For preventing the biological damage domestically, insect damage control method using chemical medicine has been applied. However, it is trend to avoid existing chemical medicine such as Methyl bromide because of the problem of being harmful to human body and environment. Therefore, the research for new medicine to replace this has been done and the interest to the physical treatment such as temperature(high & low) treatment, hypoxic treatment, carbon dioxide treatment, and radiation treatment has increased. However the systematic application standard and way has not been established. Therefore, in this research, we are going to organize present condition of domestic cultural asset preventing biological damage after the 1980's. It will also consider the direction through the characteristic of technology, limit, and replacement medicine by examining the past research.
