When the term conservation is used with regard to excavated features, it means not only conservation but also restoration. Restoring the features here does not imply restoring their original form but restoring their form at the moment of excavation. That means, the conservation of excavated features includes the concept of both reparation and restoration. The way of conserving excavated features can be largely categorized into on-site conservation and transfer conservation. On-site conservation means to conserve excavated features as they were at the excavation site. It can be further categorized into soil-covered on-site conservation, in which excavated features are covered with soil to prevent them from being damaged, and exposed on-site conservation in which the features were conserved as they were exposed. Transfer conservation is operated on the premise that excavated features are transferred to another place. It can be further categorized into original form transfer, transcribing transfer, reproduction transfer, and dismantlement transfer. Original form transfer refers to the method of moving the original forms of excavated features to another place. Transcribing transfer refers to moving some of the surfaces of excavated features to another place. Reproduction transfer refers to restoring the forms of excavated features in another place after copying the forms of excavated features at the excavation site. Dismantlement transfer refers to the method of restoring excavated features in a place other than the excavation site in the reverse order of dismantlement after dismantling the features at the excavation site. The most fundamental issue regarding conserving excavated features is the conservation of their original forms. However, the conservation of excavated features tends to be decided depending on a variety of conditions such as society, economy, culture, and local situations. In order to conserve excavated features more effectively, more detailed and specialized conservation methods should be created. Furthermore, continuing research is needed to find the most effective way of conserving them through exchange with other neighboring academic fields and scientific technology.

It is used for the epoxy resin, a mixture of various fillers conservation of cracks of the stone cultural heritage. Such as conservation treatment is need to for long-term conservation. However, field research and experiments on the conservation treatment results when included 54 cases of talc filler was confirmed that the damage, such as discoloration and cracks. The field research is talc was used to determine whether the reports and conservator interviews conducted, microscopy, ICP analysis of the samples collected from the field site. Experiments is color difference measurement and Ultrasonic measurement were arried out, and artificial weathering tests to investigate the effect of talc. As a result, lower the property of matter of the samples containing the talc. Therefore, we propose that the selection process is not allowed to use talc as the filler of stone powder filler cracks is conservation treatment.

Field experiments for Conservation damage on selected spots were carried out prior to direct conservation treatments for Bangudae Petroglyphs in Ulsan. It was found that there is a big difference in treatment effects according to the treatment technique and application rather than on the treatment material use. Based on the results of this study, a plan for the conservation treatment of Bangudae Petroglyphs will be suggested by providing new materials and application techniques for cracks, adhesive application and consolidation by conducting artificial weathering tests and continued monitoring.

Since the recent restoration of the Sungnyemun gate (South gate of Seoul) which was burnt down in 2008, there were dispute about the application of traditional technique for the conservation of cultural heritage. In this research, the definition of traditional technique for cultural heritage conservation is thought and mentioned. In general, the understanding of traditional technique is based on the idea of 'tradition'. Tradition is not defined as a 'eternal doctrine existence', but a 'development of succession' and a 'living existence'. Thus 'traditional performance and craft as intangible cultural heritage' is defined as 'intangible' which also makes it difficult to define the 'original form/state' from 'the conservation of the original form' which is a major principle of cultural heritage. In case of Korea, if the 'traditional technique as intangible cultural heritage' is put into application to cultural heritage conservation, the unclear definition will cause many problems in the restoration/conservation site. This is because the site will apply this technique without any discussion of the range and limitation of 'traditional technique'. This means there will be the lack of discussion for the conservation of the cultural heritage which will not have a strict criteria for the allowable range of usage for the 'traditional material' using the vaguely defined 'traditional technique'. In this study, these application issues of the traditional technique were also considerecl, comparing the development of international wnservation principles. As a result, the conservation of 'traditional technique as intangible cultural heritage' is important, but the 'technique left inside the tangible cultural heritage' which is the 'material which is carrying the technique when it was firstly built' has more importance to preserve and need to be in the major considerations.

After inspecting ground surface or excavating cultural heritage site, the government can take measures for the preservation of buried cultural heritage based on the related law. It means that the provisions complement the limitation of current cultural heritage management system by extending the scope of cultural heritage to be preserved. But we neither have set any matters about implementing the measures for preservation of the buried cultural heritage, nor manage the heritage and its surroundings after implementing the measures. Due to these insufficiency of the law, there arise several problems in the field. For example, the measures for preservation are not complete, or preserved cultural heritage is damaged due to inappropriate management. We have to resolve the problems in order to accomplish the original purpose of taking measures for preservation of the heritage. First, it is necessary to make sure of the legal status of preserved buried cultural heritage, to establish the standards to decide whether to preserve it or not. We need to have regulations by law or internal rule on the daily management, who should manage it, what and how the manager should manage. It is also important for local residents to take an active part in preserving and utilizing the cultural heritage as the owner. Through building up the foundation mentioned above, the meaning and value of preserved buried cultural heritage can be expanded widely.

The conservation methods for the charred-woods excavated under the Daewoongjeon Hall of Youngguksa Temple, Youngdong, Chungbuk, Korea were investigated. The tests revealed that PEG#400 10% for four days followed by gradual application of PEG#4000 10% to 40% showed the most stable and robust results, showing no cracks in macroscopic examination. This treatment method was applied to the two charred elements, which appeared to be the capitals at the excavated site. After the treatment, the consolidated capitals were transported to the laboratory, where they were retreated with PEG#4000 80% at $85^{\circ}$.... Charred capitals showed also an excellent level of stability.

When we have entered high economic growth since 1970s, many archaeological excavations were performed all over the country. Excavated objects composed of variable materials are inevitably subjected to deformations owing to surrounding environments and storage conditions. Although the importance of conservation treatment of the objects is greatly increased, a few conservation laboratories are there comparing with excavation groups. The metallic objects excavated are very unstable and deformable state. So it is important not to allow iron objects, especially cast iron, to dry out once excavated. Because the corrosion reactions on the surface proceed rapidly, the objects may be destroyed at the moment. The conservation procedures of the excavated metallic objects are as follows: (1)It is stable on-site storage method for objects to keep vinyl film with envelop or to immerse alkaline solution to prevent the environmental changes. (2)The objects must be treated at once under suitable methods in the conservation laboratory after excavation. (3)The continued existence of objects depends on environmental factors such as relative humidities, regular inspection, light etc.
