백자투각연당초문지통과 같이 기형 및 장식기법이 복잡한 도자기의 경우, 기존에 사용되고 있는 복원제는 경화시간이 짧아 정교한 성형이 어려워 틀을 이용하여 복원한다. 하지만 틀을 이용한 복원 또한 시간적, 재료적인 단점이 있기 때문에 직접 복원하는 방법을 연구하고자 하였다. 복원제의 경화시간과 물성은 작업성과 밀접한 관계가 있기 때문에 복잡한 형태의 복원부를 직접 성형할 때는 충분한 가사시간이 확보되는 복원제가 필요하다. 소성점토(Original Sculpey)와 에폭시퍼티(Repair it Quik)를 각기 다른 비율로 혼합하여 가사시간, 색도 변화, 작업성에 대한 실험을 하였다. 실험결과 OS8 : RQ2의 비율로 혼합하였을 경우 가사시간이 충분하고 성형성이 좋았으며 황변도가 낮고 채색성이 좋아 가장 효과적이라는 것을 알 수 있었다.

국립한글박물관 소장 덕온공주 집안 서대는 2019년 국립한글박물관 특별전시를 위해 소장처의 의뢰로 응급처리를 실시하게 되었다. 처리의 목적은 전시를 위한 원형유지가 우선이었으며, 서대는 훼손이 심하여 형태복원 및 탈락된 띠돈의 고정이 필요했다. 처리 전 서대의 이론적 연구를 통해 구조의 명칭, 시대에 따른 형태의 변화 등을 살펴보아, 보존처리의 방향 및 계획을 수립하는데 기초로 삼았다. 품대 중 서대는 1품의 품계를 가진 사람이 사용하는 품대로 왕의 옥대 다음으로 귀하게 여겨졌던 품대이다. 서대를 장식하는 무소뿔[서각]은 품질에 따라 3가지 양식의 무늬로 구분되는데, 그 중 주변으로 작은 원형의 흑갈색 무늬가 중앙에 밀집한 모습으로 포도문과 유사한 양식으로 고급품에 속하는 질 좋은 서대임을 추정할 수 있다. 또한 버클이 없는 일체형 구조이며, 각이 진 방형의 품대로 19세기 이후 주로 착용되는 품대의 형태와 동일한 것으로 확인 하였다. 이후 보존처리를 시행하는 과정에서 서대의 구조를 확인하여 제작방식을 파악하였으며, 유물과 초상화 자료와의 비교를 통해 시대에 따라 변화되는 서대의 형태적 특징, 그리고 세부 구조 등을 살펴서 보존처리 대상 유물이 19~20세기 제작된 서대의 특징이 나타나고 있음을 한번 더 확인할 수 있었다.

There were excavated many relics about 200 pieces including gilt-bronze cap, gilt-bronze shoes, bronze mirror and armor, etc. in Ahndong tumulus, Gildu-ri, Goheung. The National Research Institute of Cultural Heritage was undertaking excavation of major damaged relics that were corroded by several environment and were destroyed by a lump of earth. Shoes are consolidated with soils in order to stop destroy during excavation. And these are relocated in order to treat for conservation. Before treatment, X-ray radiography and CT(Computed Tomography) are used in order to examine the original surface and the shape of shoes. As a result, we confirm the condition of shoes. If soils are removed, gilt-bronze shoes are crumbling into little pieces because gilt-bronze shoes are damaged by corrosion and deformation. So, shoes are consolidating with inner soils and are removing outer soils. Throughout conservation treatment, shoes recovered original form and inner soils are consolidated in order to keep the shape of shoes.

The purpose of this study is to identify the level of children's consciousness and behavior for the environmental conservation, so that provides some fundamental information for the overcome of environmental crisis and reinforces a consumer education for the childrens at home. The subjects were randomly selected form the 4th, 5th, and 6th grade of elementary school students, in April, 1996, Seoul, Korea. The 1342 data obtained were analyzed by Mean, t-test, ANOVA, duncan's Multiple Rang Test, Pearson correlation, and Regression. The major findings were as follows: 1) The average level of children's consciousness for the environmental conservation was relatively low, which was 1.79. There were significantly differences on the children's consciousness for the environmental conservation, according to student's grade level, housing type, parent's education, household income, and the level of consumer socialization. 2) The average level of children's behavior for the environmental conservation was low, which was 2.36. There significant differences on children's behavior of environmental conservation, according to student's sex, grade level, housing type, parent's education and occupation, household income, and consumer socialization. 3) There were significant relationships between children's consciousness and behavior for the environmental conservation. 4) The most influential variable for children's consciousness and behavior of the environmental conservation was consumer socialization. As we see above, this study concludes that consumer environmental education should be reinforced for the children in the home, so that they involved in the environmental activities and have an early experience.

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.

In this paper, we described a technique for the swing-up control of a 2 link acrobat robot using a cannonical form which is derived form the law of conservation of an angular momentum based on the center of the first joint. The wide usefulness of the canonical form of the acrobat robot, which was suggested here, is could also be applied to control a free flying robot or an underactuated planar manipulator with no gravity term. Some simulation results are provided to verify the effectiveness of the proposed algorithm

석조문화재는 '석재'로 만들어진 문화재로 조성 목적에 따라서 여러 형태를 빌리고 있다. 그 중에서 석탑(승탑 포함)과 석불(마애불 포함)이 가장 많으며 문화사적 및 과학기술적 측면에서 가장 중요하다고 판단된다. 문화사적인 것과 과학기술적인 특징은 왜? = why? 그리고 어떻게? = how?의 관계로 나타낼 수 있다. 전자는 이유, 원인 등으로 철학적인 면을, 그리고 후자는 방법론적인 면을 의미한다. '왜?' 그들은 석탑과 석불을 제작하였으며 '어떻게' 그것들을 조성할 수 있었을까? 이와 같이, 석조문화재는 대부분 (1) 정치-사회적, (2) 종교적, 그리고 (3) 문화사적 배경에 따라 형태적 측면의 영향을 받는다. 그러므로 문화재가 조성된 배경을 종합적으로 조사 및 분석하여 석조문화재 보존처리를 위한 원칙과 방법론에 대해 기술하고자 한다.

In this pressentation it is argued that the heterogeneity of a hydrologic attribute which may seem to be nonstationary at one scale, may become stationary at a larger scale. The fundamental reason for transformation from nonstationarity to stationarity whith the increase in scale is the phenomenon of coarse-graining of the hydrologic processes with increasing scale. Due to the phenomenon of aliasing, a particular scale hydrologic process heterogeneity which is observed as a nonstationary process at that scale, may be observed as a stationary process at a higher(larger) scale whose size is bigger than the stationary extent of the lower scale heterogeneity. As one goes through a hierarchical sequence of larger and larger scales for observations, one would eliminate nonstationarities which emerge at some lower scales at the expense of losing information on the high frequency fluctuations of the lower scale heterogeneities which will no longer be observed at the larger sampling scales. We call this phenimenon as the "coarse-graining in hydrologic observations". In this presentation, it is also argued that by the coarse-graining of hydrologic processes due to the averaging and aliasing operations at increasing scales, the conservation laws corresponging to these scales may still be quite parsimonious, and need not be more complicated as the scales get larger. It is shown that shen a higher(larger) scale process is formed by averaging a lower(smaller) scale process in time or space, the high frequency components of the lower scale process will be eliminated by the averaging operation. Thereby, the resuliiting average hydrologic dynamics, free from the effects of the high frequency components of the lower scale process, can still be quite simple in form. This is demonstrated by means of some recent upscaling work on the solute teansport conservation equation for hetergeneous aquifers. By means of this solute transport example, it is also shown that for the ensemble average form of a hydrologic conservation equation to be equivalent to its volume-average form at any scale, the parameter functions of that conservation equation at the immediately lower scale must be ergodic.
