A Urethane resin restoration material was made to be used in the restoration of stone cultural assets. The Urethane resin restoration material showed strong adhesive strength and tensile strength similar to epoxy recovery material, which had been mainly used for the recovery of stone cultural assets. The sealing property, anti-shrinking property and paint-ability of Urethane resin restoration material are also similar to existing epoxy system restoration materials. Especially, this Urethane resin restration material is expected to give permanence and continuous stability in the restoration of cultural assets made in stone by resolving the two big issues of existing epoxy recovery material, which are 'yellowing' and 'ir-reversibility'. This Urethane resin restration material had been directly applied as a filling material and adhesive and it was dissolved again. The Urethane resin, which had been used for the recovery, was able to be perfectly removed, which means that this Urethane resin recovery material has perfect reversibility. This Urethane resin restoration material also has enhanced convenience since user can adjust the working-life dependent on work environment. It is believed that this Urethane resin restoration material can also be used as a filling material or adhesive for other cultural assets made of ceramic or metal heritage, in addition to stone, since it has strong adhesive strength and tensile strength.

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.

The purpose of this study was to investigate social workers' personal experiences providing social support to multi-cultural family in a multi-cultural family center. The data were collected through in-depth interviews with 14 social workers at the multi-cultural family center, and were analyzed using a phenomenological research method. The major findings were as follows : The social workers' personal experiences with and understanding of social support were classified as 4 categories : 'source of emotional support to the multi-cultural family', 'diverse and systematic educational support', 'excessive demands on material support', and 'daily life support and connection with community network'. The social workers recognized emotional and educational support as essential factors in providing social support to multi-cultural family. However, the social workers' perceptions of material support derived from negative personal experiences stemming from excessive demands and misunderstanding for material support. These results showed that social workers at the multi-cultural family center provided multi-cultural families with social support and that they interacted with community support system and multi-cultural families to increase their satisfaction.

A view of cultural heritage as a form of capital considers the long term, dynamic, evolutionary, inter-temporal and inter-generational aspects of cultural heritage. The principles of sustainability provide a basis on the broader issue of culture in economic development. They might be capable of specifying a pattern of development that is "culturally sustainable" in the same way as somewhat similar set of criteria derived for the natural world, the criteria for defining ecologically and environmentally sustainable development. Thus we might accept the principles of material and non-material advancement, intergenerational and intra-generational equity, the maintenance of cultural diversity, the precautionary principle, and the recognition of system interdependence as benchmarks in assessing a cultural development process.

Hanji among paper, which is material for support of the organic artifact such as painting and Thangkas, is given as much importance as the original material in the conservation treatment of artifacts. This lining paper can go through physical and chemical deterioration due to its organic nature, and inflict serious damage to the original materials of the artifact. There is a lot of difficulty in keeping continuous production of the paper mulberry fiber based on lining paper due to a short supply of raw material and discontinuation of traditional method. Also restoration and conservation treatment is done by relying only on the knowledge and skill of few experts without any recognized manual based on scientific analysis. In this study, we evaluated the stability of lining paper which is used to support organic artifact. As the result of experiments, this lining paper was made from mulberry tree in Korea and produced by means of oebal method, but was not treated by starch in its surface.

In this paper, conservation treatment processes for the wooden furniture in the Presidential Archives are introduced. Conservation treatment strategies for modern wooden cultural heritage have been increasingly studied. The current study uses materials similar to those used by the existing conservation treatment method. Material analysis showed that the chair(Lee136-2) and desk(Yun37) in the Presidential Archives are made of Dipterocarpaceae, and both are coated with two layers of varnishing. FT-IR analysis showed that the varnish has a similar spectrum to that of a nitrocellulose-based lacquer(Lee136-2) and top coat(Yun37) and confirmed that a synthetic material was used. Pollutants had adhered to the surface of the wooden furniture and it was also in structurally unstable condition because of cracks and damage to the varnish and wood. Therefore, a conservation treatment was carried out to restore the damaged areas to their original appearance using similar kinds of materials, based on data obtained by materials analysis.

In this study, a scientific survey on the material of the mother-of-pearl floor mirror was conducted and conservation treatment processes were introduced. The survey results showed that the mother-of-pearl floor mirror in Daejojeon Hall of Changdeokgung is made of Dalbergia spp., and repair work seems to be done later with shorea spp. FT-IR analysis results showed that the varnishing is similar to the spectrum of lacquer. The metal wheels and metal line decorations set with mother-of-pearl were found to be made of brass based on XRF analysis, and the ingredient ratio showed that these were made in modern times. Foreign materials were stuck on the surface of the mother-of-pearl floor mirror before conservation treatment, which was in a structurally unstable condition owing to some missing submaterials. Conservation treatment was conducted on the damaged area to restore the mirror to its original appearance by using the same species of wood determined from the data obtained through the scientific survey.
