Stone cultural heritage will either be damaged by composite damage or will lose its original historical authenticity starting with the moment it is created. Various artificial interventions to restore them to their original state have been described, centering on the conservation treatment case of the Stupa of State Preceptor Jigwang from the Wonju Beopcheonsa Temple Site. Restoration of the Jigwang stone pagoda was carried out after securing all scientific and technological means for the research and protection of the cultural heritage in question. Since its restoration was promoted to retain its aesthetic and historical value and was based on a careful understanding of the original materials and prototypes, extensive restoration was sought, which contributed to the restoration of the original form, resulting in both preservation and authenticity.

Recognizing that the debate on the original form of the Seokguram Grotto is closely related to the mythologization of the Seokguram Grotto, which is far from factual understanding, this paper is prepared to restore the Seokguram Grotto based on scientific facts. To this end, we will first analyze its active meaning and fiction from three directions: the founding legend, the rediscovery story, and the concept and discourse of the Line of sight for Buddha statue (對佛像視準線), which have contributed to the mythologization of the Seokguram Grotto. The original restoration of the Seokguram Grotto should be based on a scientific understanding of the Seokguram space. However, past debates and restoration attempts have been based on imagination and not on scientific knowledge. Therefore, Chapter 3 attempts a scientific analysis of the light environment of thr Seokguram Grotto and critically examines the existing errors and realistic mythological images to correct the public's spatial perception of Seokguram's architecture and to propose a rational restoration of Seokguram's architectural space.

We propose expert system for restoration the original character form of ancient relics based on image processing and computer graphics. Letters engraved in relief like relics and intaglio like curved tombstones and letters engraved in plane or curved part of cultural asset may have been broken by a lot of rubbed copy, a long time and tide. In this paper, we suggest a new method for extracting and recovering the broken letters of cultural asset into an original form by using Z-map, morphological filter, and high frequency filter. Based on the suggested method. we develop the character recovering system.

Oral cancer treatment involves the surgical removal of all or part of the maxilla, leaving the patient with a defect that compromises the integrity and function of the oral cavity. The postoperative restoration of esthetics, deglutition, and speech shortens recovery time in the hospital and expedites the patient's return to the community as a functioning member. The surgical obturator is the proven treatment option in such situations. This article describes a simple technique to fabricate a surgical obturator that restores patient's original dentition and facial and palatal tissue form. The obturator fabricated with this technique utilizes the vacuum formed index of patient's original tissue form and duplicated partly in heat and partly in auto polymerizing acrylic resin. Duplication of the original tissue form helps patient to minimize the immense physiological trauma immediately after the surgical resection. The obturator fabricated with this technique supports soft tissues after surgery and minimizes scar contracture and disfigurement, and thus may have a positive effect on the patients' psychology.

Image restoration is the process which estimates the original image form the blurred image observed by the non-ideal imaging system with additivenoise. According to the regularized approach, the resotred image can be obtained by iterative methods or the constrained least square error(CLS) filter. Among those retoratin methods, despite of many advantages, iterative iamge restoration is limited in use because of slow convergence. In the present paper, fast iterative image restoration algorithms based on preconditoning are proposed. The preconditioner can be obtained by using the characteristics finite impulse response (FIR) filter structure.

In cases, such as white porcelain with openwork lotus scroll design, where the ceramics has intricate form and decorations, we normally use casts to restore the work, in that current restoration materials have short molding time which causes difficulties in delicate work. However, since using a cast for restoration requires longer work-time and uses more materials, we decided to restore in direct. Since the molding time in the restoration material is closely related to the workability, restoration material which secures longer work hours is necessary when directly restoring a complex form of body. Therefore we experimented on the work-time, color variation and workability as time passes by making mixtures of Epoxy putty and Baked clay in different ratios. As a result of the experiment, the mixture ratio of OS8:RQ2 turned out to be the most effective ratio.

Horse armour from Dohang-ri site had been retained its original form and all iron metal fragments of armour were very completely corroded without remaining metal core. Horse armour excavated is archaeologically very important, Also it should be maintained the original form. So, only moderate treatments such as brushing and consolidation techniques were performed. The processes for the conservation is as follows : 1) preliminary investigation, 2)removal of chlorides and corrosion products, 3) consolidation with 40% ParaloidNAD-10, 4) joining and restoration

This essay explores the problems with applying the concept of "original form" to natural heritage when it is based on originality and diachronic, historical period. It also suggests an alternative perception that the concept of "original form" can be considered based upon "integrity". First, the conceptual framework for applying the concept of "original form" falls into three types: one that centers on the time point at which heritage originated; another that respects the diachronic characteristics of the concept of "original form"; and the last that bases original form on a particular time after the heritage originated. Second, the national policy for the conservation of natural monuments and scenic sites stayed at the level of consulting the Decree on the Preservation of Treasures, Historical Remains, Scenic Sites, and Natural Monuments of Joseon, under Japanese colonial rule. And after the legal framework was established through enacting and proclaiming of the Cultural Heritage Protection Act in 1962, 564 cases have been designated as natural monuments. Third, the natural conservation movement, the first national policy for natural heritage, was initiated from the heritage field, but the Environment Ministry subsumed all nature-related policies and ever since the heritage agency (Cultural Heritage Administration) has implemented only heritage policies regarding "cultural" heritage. The present state of the coexisting policies about the natural heritage by the Environment Ministry and the Cultural Heritage Administration resulted in leading the public confused about official terms and main policy agency of natural heritage. Fourth, the difficulty of applying the concept of "original form" to natural heritage stems from the fact that natural heritage is inherently distinct from cultural heritage, which is placed at the center of the heritage policies implemented by the heritage agency. In addition, natural heritage, similarly distinct from the overall natural environment, has evolved in a way that incorporates human culture and thus diversely includes characteristics of originality, diachrony, and historical period. Under these circumstances, an incorporative, professional approach is required rather than independent approaches for each type of natural heritage. In conclusion, this essay suggests that issues related to the restoration of original conditions of natural heritage should be resolved through the application of the "integrity" concept by restoring "the characteristics of an object or a place that imbue it with meaning and value," with consideration given to efforts for alleviating logical contradictions within the concept of "original form" through the preparation of standards and guidelines for the restoration of original condition.
