Ancient tombs are typically comprised of confined rooms, which have different spatial characteristics than the external environment because they are covered by heavy layers of soil. In this study, we examined the thermal energy flow from the outside to inside of Songsan-ri tomb No. 6. External heat flows slowly to the inside because of heavy soil layer, and the presence of several rooms and entrances. For this reason, it takes about two months for the air temperature to travel from the outside to the inside of the tomb. Interestingly, the gradational inflow of thermal energy from outside the tomb leads to delicate horizontal and vertical variations in the wall temperature. These micro-environmental differences occur in the inner tomb every year, so we can expect them to cause condensation with regularity. In addition, we show that the previously installed forced circulation air conditioning system risks fatal damage to the mural wall painting. The results of this research suggest an optimal air conditioning system and optimized space planning to conserve Songsan-ri tomb No. 6 and its mural painting.

The most important part of conservation treatment of murals is to preserve them against the risk of a damage by injecting fixative into them when the painting loses its cohesion or powderization of pigments occurred due to occurrence of cracks inside the painting layer. However, studies on the stability of fixative used for painting layers of murals are still insufficient. This study manufactured a mural as a specimen and colored it with four kinds of pigments including oyster shell white, cinnabar, malachite and red clay and applied four kinds of fixative, including, Paraloid $B-72^{(R)}$, Caparol-$binder^{(R)}$, glue and Hydoxypropyl $cellulose^{(R)}$. artificially generated environmental changes in temperature, humidity and ultraviolet rays which may occur after the completion of conservation treatment. Then the changes in physical properties were observed in multifaceted ways such as color stability, contact angle, brilliance, adhesive strength and surface. As a result, this study found that ultraviolet rays and hot?humid environment have a large impact on color stability causing changes in brightness and chroma of all painting layers where the fixative were applied, except for oyster shell white and are considered the main factors of decomposition by accelerating the aging process of fixatives applied. In comparison to the synthetic resins that were also tested in this study, the traditional glue showed satisfactory results in terms of color stability and influence preservation and the hydrophile property. As it showed exceptionally outstanding adhesive strength in all painting layers in the aspect of adhesive strength, it is considered to be highly stabile for the fixation treatment of painting layers of mural.

This study aimed to identify weathering factors and to assess the conservation environment through microclimatic analysis of Hyeonpung Seokbinggo (ice-storing stone warehouse). The stone blocks inside Seokbinggo suffered crack, displacement, break-out, exfoliation, efflorescence, brown and black discoloration, and biological colonization. Biological colonization represented the maximum deterioration rate(24%) among those weathering forms. The indoor microclimate showed parallel patterns with outdoor one, but the indoor temperature and relative humidity ranged far narrower than outdoor and remained steady. The environmental characteristics resulted from blocking-out of outdoor heat by the closed entrance and surrounding microtopography. This prevented water condensation and freezing effects, so that it reduced physical deterioration of rock, and maximized ice-storing effect for long time. However, contrary to positive effect, extremely high relative humidity over 99% accelerated biological colonization inside the Seokbinggo.

The study of corrosion products generated by archaeological bronzes that have been buried for a long time can provide certain evidence that enables us to understand the natural corrosion process of bronze and helps us develop conservation and preservation methods. In the present study, the specimens taken from two bronze mirrors and three bronze swords were used to study the corrosion morphology and the related phenomena such as selective corrosion of ${\alpha}$ or ${\alpha}+{\delta}$ phases, decuprification, destannification, and secondary copper. Furthermore, corrosion development was discussed based on the ions distributed throughout the corrosion layers.

The "Historic city Preservative law" was legislated for the preservation of cultural properties and enacting regulations of managing the environment around them in 2004. This law was revised to "Historic city Preservative and Development law" in 2012, and specified the criteria for permissible behaviors in the preservative district. Therefore, this paper focused on the ancient capital Gyeongju and developed a comprehensive system for evaluating the value of the ancient historic district based on Analytic Hierarchy Process (AHP). Through the evaluation of the ancient historic districts, which are the pilot project districts in the "Gyeongju Ancient Capital Preservation Plan", some preferential projects were objectively proposed. As a result, according to the evaluation among 10 ancient historic districts in Gyeongju, Daereungwon got a score of 78.34, which is the highest among 7 special preservation districts. On the other side, the Gyo-dong area got a score of 76.14, the highest among 3 historic and cultural environmental districts. Finally, for the preservation and development of Gyeongju, some efficient preservation and development plans were objectively proposed for the pilot project districts in the "Gyeongju Ancient Capital Preservation Plan".

Deterioration and brittleness of resources on the shelves of institutions such as libraries and archives have been increased and accelerated as time passes in accordance with the preservation environment and the nature of their own material. It can be a loss of current information with little importance in prolong the life of valuable materials and to preserve them in security, integrated preservation programs should be developed and implemented according to missions, sizes, the nature of collections, users, and budgets of individual institutions. In reality, most institutions, however, are not able to implement perfect preservation programs due to lack of budget, human resources, and expertise. To solve this problem, some institutions in similar circumstances have planned cooperative preservation programs in various levels. Through cooperative systems individual institutions can not only pursue common interests but gain real benefits for themselves. Consequently institutions are recommended to collaborate with in development and implementation of various preservation programs at local, national, and international levels in addition to individual institutional programs.
