In order to establish the procedures for investigating environmental influences to wooden cultural property, existing study data were surveyed and necessary steps for performing the investigation works were presented to be applied for the future works in this country. Environmental factors which influence to the conservation of wooden cultural property should first be studied for items concerned with their damage situations. On basis of these data, laboratory works to yield the standard value for each factor should be conducted by means of testing samples exposed under laboratory simulated environmental conditions. Outdoor measurements may be followed for samples exposed to the open air at the site of that property. These data may be compared with those of laboratory standard value and overall evaluation for the factor influencing mostly tn the damage status of that property may further be conducted. Referring data obtained in this investigation, necessary measures to be taken for conserving that property may be able to be established.

World state of the arts of the conservation of stone monuments is reviewed and the modern conservation program based on conservation science is proposed for the scientific conservation of stone monuments in Korea. The conservation program suggests that the site environment diagnosis, decay diagnosis, petrophysical property analysis, and conservation experiment should always be carefully studied before conservation treatment. It is an up-to-date widely accepted concept in the world of stone conservation science. Our urgent national tasks that should be accomplished for the scientific conservation of stone monuments in Korea are proposed in the following: 1) The stone monument conservation projects should be planned in accordance with 'Conservation Concept of Stone Cultural Properties' and executed in accordance with the proposed 'Conservation Program for Stone Cultural Property' based on conservation science. 2) It is proposed that 'National Institute of Conservation Science for Cultural Properties' be established for systematic conservation research on the tangible cultural properties. 3) The conservation projects of stone monuments should be executed under the control of stone conservation specialist for their quality control. 4) Special national budget should be prepared for quick development of researches on conservation science in Korea.

전통 단청 교착제인 젤라틴(아교)의 물성에 따른 단청 도막의 성능을 평가하고자 직접 추출하거나 시판되는 아교 및 젤라틴 5종을 선정하고 수분반응성과 촉진내후성을 실험하였다. 실험결과, 겔 강도가 높은 1종의 젤라틴 단청 도막에서는 아교 대체 재료인 아크릴산 에스테르 수지 도막보다 수분 흡수율이 높고 촉진 내후성 시험 후에도 밀착성이 높았을 뿐만 아니라 젤라틴 도막보다 내수성이 우수하였다.

The society for conservation of local historical properties in Korea originated in Japan. It was transplanted by Joseon Governor-General to represent their positions in the field of the conservations of the cultural properties. Also the society for conservation of local historic properties represented the positions of the provincial government office because the representatives of that societies were the chief of local government offices. At that time, the fundamental concept of the historical property conservations was not settled, so they accomplished the conservation activities as the necessary way for themselves.They often made a proposal about repairs for conservation of historical building and suggested a application for the national budget. And they contributed to carry out the repair works of the historical properties in the early Japanese colonial period. But they was usually used to invigorate the tourism and to publicize the regional characteristics through the historical properties. Although the societies were privately-managed as a matter of form, they were governmentally-managed as a matter of fact. It was the limits of the societies for conservation of local historical properties at that time.

The application of reinforcing agents with hydraulic property and strength development characteristics was studied under conditions similar to those of mural-painting mortar made with oyster shell powder. Reinforcement mortar made with oyster shell powder showed hydraulic properties and strength to supplement the weaknesses of natural hydraulic lime(NHL); this confirmed its possibility as a wall-reinforcing material with enough strength for preserving mural paintings. Reinforcement mortar 1 showed hydraulic property and general characteristics of lime mortar, such as consistency and viscosity, as well as lower strength and higher whiteness compared to an NHL product. For Reinforcement mortar 2, the original wall sample characteristics were reflected by mixing more shell produced through calcination; and it showed similar strength to that of Reinforcement mortar 1 as well as high whiteness. In measuring the contraction ratio of reinforcement mortar samples, Reinforcement mortar 1 and 2 showed more stability in property change compared to the NHL Group.

Radioisotopes and their related techniques have recently been applied for scientific conservation works of cultural property and resulted many excellent findings or conservation data which could never be achieved by means of other techniques. Radiocarbon dating have widely been applied for dating the antique of organic origin, whereas the determination of radioactive contents in metal, ceramics, environmental soil, and classical objects could be able to afford many useful informations on the age, genuiness, and archeological significances as it had been produced. Trace quantity of contents of each antique have successfully been analyzed by means of radioactivation analysis or radio active tracer techniques, which could afford important technical data and results for tile conservation of each object. Radiography have also been applied for detecting the internal defects of metal objects and furthermore $\beta$-and ${\gamma}$-ray radiography were proved to be effective for such thin material as textile, painting, and fibres. In this article the detailed principle and procedures of each technique were presented so that the society could be able to make efforts to familiarize all concerns with these modern trends of the conservation techniques of cultural property.

A paulownia wood has been widely used with various advantages as its low weight, permeability, convenient workability and aesthetic patterns for a long time. However, the related empirical researches and simultaneous evaluations of functionality are insufficient compared with acid-free archival boxes for now. In this study, the indoor and outdoor temperature and relative humidity control and heat release rate were evaluated under the controlled and uncontrolled circumstance in 2018. The paulownia wood storage box showed superior control effect of relative humidity than the acid-free archival box in constantly uncontrolled environment. Also, the possibility of the flame diffusion from the surface of the materials was higher for the paulownia materials, and the acid-free archival box showed more dangerous patterns in the early stages of the fire.

국가배상법 제5조 영조물책임법리에 적용되는 대표적인 영조물에는 인공공물인 도로와 자연공물인 하천이 있다. 최근 하천범람과 수재로 인한 국민들의 피해가 빈번하게 발생하고 있고, 국민들도 더 이상 천재로 보지 않고 인재로 보고 국가배상을 청구하는 경향이 있다. 특히 하천의 범람, 하천제방의 붕괴로 인한 수해가 빈번히 발생하였고, 개수중인 하천에서 다시 수해가 발생하는 경우도 일어나고 있다. 그리하여 국가는 하천관리상의 하자로 인한 손해발생에 대한 책임을 떠맡아야 하며, 하천관리시설의 확충과 내실화를 기울여야 함과 아울러 책임범위를 확대해야 하는 시점에 왔다고 본다. 따라서 본 연구의 범위는 국가배상법 제5조 영조물의 설치 관리상의 하자로 인한 손해배상 중 하천관리상의 국가배상에 한정하기로 한다. 이러한 범위내에서 자연공물에 해당하는 하천관리상의 하자로 인한 손해배상에 관한 제반 법리와 판례를 분석 검토함에 따라 하천관리를 둘러싼 국가배상책임에 관한 문제점과 대처방안을 모색하는데 연구의 목적이 있다.

A finite element scheme is considered for the viscous Cahn-Hilliard equation with the nonconstant gradient energy coefficient. The scheme inherits energy decay property and mass conservation as for the classical solution. We obtain the corresponding error estimate using the extended Lax-Richtmyer equivalence theorem.
