The domestic wooden cultural properties applied to the sprinkler extinguishing system was confirmed extinguishing performance through fire experiments. Consists of wooden cultural properties of a fire, a flammable material is vulnerable in terms of. The scale of fire will occur to vary appearance of the initial fire in case of arson. Sprinkler nozzles of the characteristics, the discharging pressure is 1 bar and the flow rate is 80 lpm, applied in this experiment. Fire performance experiments were tested in two separated in each of the scale of the fire and cultural properties. Fire extinguishing performance test results was low in high ceilings and two or more units of the fire scale. Fire growth environment of the actual wooden cultural properties to experimental models when you consider that it is more vulnerable, sprinkler extinguishing system is required sufficient verification in order to apply fire protection of the wooden cultural properties.

This study is a research examining reshaped pattern in the perspective of repairing parts and materials through repairing renovation of registered cultural properties constructed in modern times and results are as followings. Repairing construction of registered cultural properties of Jollanamdo according to parts is shown numerously in the order of roof, walls and windows, and mostly outworn as time passes on and leakage were the main cause of repair. Also when original shape was damaged by previous repair in the past, and this was another reason of repairing. It was surveyed that among the repairing job repair of damage occurred on the part of roofing area including water leakage, corrosion and damage of roofing material, and damage of groove channel were the most main cause of repair. Especially when roof leakage is occurred by outworn of roofing materials, this cause corrosion and damage of materials due to the damage of leakage parts and this cause repeating cycles of worse leakage again and again. Main repairing materials which deform the original shape of registered cultural properties were confirmed as copper plate used on the roof. Copper plate showing high frequency of application which replaces groove slate or cement roofing tile used on the roof before has high durability and anti-corrosion but it is considered improper material to recover original shape.

All excavated "buried cultural properties" are supervised by the Cultural Heritage Administration that decides whether to conserve them or not, depending on the necessity for conservation. Currently, there is no legal regulation concerning the administration of relics (including artifacts) and remains (including archaeological sites) that are relocated and restored based on such conservation decisions. Thus, administration of these cultural properties is inadequate. Under these circumstances, this paper recommends the current state of conservation and conservation methods for buried cultural properties excavated at Chungcheongnam-do thus far. Conservation of buried cultural properties excavated at Chungcheongnam-do primarily employ the "relocating and restoration" method; 23 relics and 46 remains employed relocation after dismantling and soil layer transcription method. Moreover, 27 remains were relocated after dismantling and 14 remains employed the transcription method. In terms of area, Buyeo-gun and Gongju-si had 12 relics accounting for about 50%, while according to the period, Baekjae period had 16 relics, accounting for about 70%. In terms of conservation facility, open-air facility had 33 relics, accounting for about 72%. Results of investigating the state of relics' management indicated that public institutions like a museum with a recognizable management system had their own work force and consequently ensured excellent conservation, whereas if there were no apparent responsible bodies, remains were subjected to considerable damage due to mismanagement. Therefore, this problem can be resolved by identifying a recognizable management body as well as ensuring periodical management and supervision. The excavated buried cultural properties are utilized not only for academic purposes, but also for PR or as exhibition material. Hence, this study confirms that meticulous management of buried cultural properties is currently required.

The cultural properties are damaged by various causes according to the characteristics of material, the condition of preservation, and the period of time. Especially, biodeterioration makes lots of damages in organic properties than inorganic ones. The damages of wooden cultural properties by insects usually are caused by the three orders; Isoptera, Coleoptera, and Hymenoptera. As the result of investigation on the state of 141 buildings of wooden cultural properties in 1999, some of them were damaged by many kinds off actors; wasp, powder post beetle, cigarette beetle, termite, decay, and physical cracking. And it was found that the patterns of damages were related to species-specific habits of insects. There are several methods of pest control for the prevention of wooden cultural properties from damages caused by insects. Those are as follows; physical control, chemical control, biological control, and integrated pest management. When insects and fungi were detected at the wooden buildings, the fumigation is best treatment to stop biodeterioration. And then, wood materials also need to be treated with insecticidal and antiseptic chemicals to avoid a reinfestation, because the fumigant is volatile. The six commercial chemicals which are applied to the insecticidal and antiseptic treatment of wooden cultural properties were purchased to test their abilities. According to the comparative results of efficacy of them in laboratory, chemical D showed excellent efficacy in all items, including antiseptic and termiticidal items. The goal of these pest controls is to protect wooden buildings from insects and microorganisms. The most effective method used currently is chemical control(fumigation, insecticidal and anticeptic chemical treatment), but it has to be treated periodically to control pest effectively. Recently environmentally-friendly control methods such as bait system or biological treatments are replacing traditional barrier treatments using large amounts of chemicals. Especially, termite is a social insect which makes a colony. Although a building with fumigation treatment is safe for a while, once attacked building has a risk of damage by reinfestation of termite. Therefore, to control termites from damaged building, the entire colony including reproductives(queen and king) and larvae around buildings must beeliminated. Bait system can be used as a preventive measure in early detection of them through termites colony monitoring and baiting. It would be the most effective for termite control if bait system would be used together with the chemical controls.

We have conducted the study of distribution and inhabitation of the aerial algae from five stone cultural properties located in Gyeonggi-do. A total of 21 taxa were identified, among which 8 taxa of cyanophytes, 12 taxa of cholorophytes and one diatom species. Protococcus viridis, Ulothrix zonata, Synechocystis aquatilis and Chroococcus varius occurred in 15, 9, 8 and 7 study sites, respectively. These coccoid types appeared more frequently than filamentous types. In this study, Chlorococcum infusionum, Cylindrocystis gracilis, Klebsormidium crenulatum, Klebsormidium dissectum and Klebsormidium flaccidium newly recorded from Korea. We found that 80% of stone cultural properties had aerial algae and their 58-84% were grouped into Class 5 based on chlorophyll-a concentration.
