The objective of this study is to establish the method of conservation for traditional Korean settlements, based on the field surveys on the representative traditional settlements in Korea and China. The method is approached from grasping the conservation mechanism in which non-physical aspects deeply influence physical ones. The study has analyzed the characteristics and problems in the current methods of conservation for the traditional settlements, through comparing conservation practices at the World Heritage-class settlements such as Yangdong, Hahoi, and Oeam villages in Korea and Xidi-cun, Hong-cun, and Dangjia-cun in China. As a consequence of the study, the conservation method for the traditional Korean settlements is established as follows; Firstly, the conservation targets are classified into 4 types in terms of the relations of elements; individual, correspondent, sequential, and network elements. Secondly, the conservation strategies include the structuralizations of targets, by means of sequencing and networking. Thirdly, the conservation programs are made in consideration of the sustenance, transformation, replacement, and extinction of traditional use patterns.

가정부문 에너지소비는 국가마다 중요한 에너지절약 목표로 간주되고 있다. 이는 에너지절약 측면뿐 만 아니라 소비자의 경제적 지출 측면에서도 매우 중요한 문제이다. 특히 가정부문 에너지소비는 소비자의 라이프스타일과 매우 밀접한 관계가 있다. 그럼에도 불구하고 이에 대한 심도 있는 연구는 거의 없었다. 이에 따라 본고는 구조방정식 모형을 통해 에너지절약행동에 있어서 소비자의 라이프스타일 유형이 어떠한 영향을 미치는지를 살펴보았다. 연구결과, 생활만족형 절약의식형 및 절약실천형 라이프스타일은 환경보전의식 및 환경보전의식과 정(+)의 관계가 있으며, 경제적 비용인식과 환경보전의식은 에너지절약의식과 정(+)의 관계로 확인되었다. 그리고 에너지절약의식과 에너지절약행동은 정(+)의 관계가 있는 것으로 분석되었다.

Stone cultural heritages in Korea have a severe damages from chemical and biological weathering because most of them have been situated in outdoors without any suitable protection systems, and this in turn causes deformation and structural damage. To counteract these problems and increase durability, various kinds of conservation materials are used in the conservation and restoration treatments. However until now there are not many practical and technological experiments on this subject. This paper attempts quantitative evaluation of effectiveness about chemical of ethylsilicate based resin for sandstone in Yeongyang-gun. It takes a long time to evaluate durability and side effect after conservation materials treatment. So we use artificial weathering through freezing§ thawing experimental method. As a result of this experiment, porosity and absorptance increased, and elastic wave speed, elastic modules, unconfined compression strength and tensile strength decreased more than before. This study plans to make a scientific method study about weathering factor and mechanism, and to deduce correlation between artificial weathering and natural weathering.

In general, collections in museum are kept in storage according to a preservation and administration program in long or short term, after conservators' conservation treatment. Museum activities related to conservation science are common to do before and after exhibitions. That is, the museum collections include a flow mechanism, which circulate a space in where conservation science related activity is carried on centering around its storage. The purpose of this study is to suggest the design guidelines of a conservation area in a museum. The results of this study as follows. First, to program space planning, conservation area of museum is divided into 4 kinds of zone. Second, space for relics unloading in basically includes 'unloading room', 'control room', 'worker room', 'unpacking room', and 'unloading tools storage' and considers to install 'outdoor arrangement space', etc. In case of space for making relics collections, 'arrangement room' and 'temporary storage' are separately planned in order to arrange and temporarily store relics taken in. Conservation analysis space should be divided into 2 kinds of zone, 'conservation analysis lab' for analysis of collection characters and 'restoration lab' for conservation treatment in the bigger museum. In case of large-scale museum, conservation treatment space is basically classified with characters of museum collections. And it considers installing 'waterlogged wood lab', 'painting clothes treatment lab', 'storage of treated relics' etc. Third, for 'the spaces for analysis treatment', must consider activity contents and sizes of the department for scientific conservation every museum, can classify in detail required space, and must review the space for relics settlement in construction.

The Annals of Joseon Dynasty, which recorded governmental affairs for 472 years (AD 1392-1863) during the Joseon dynasty is an representative paper cultural heritage in Korea. Being recognised their authenticity and values they were designated as the No 151 national treasure of Korea in 1973 and registered as 'The Memories of the World' by UNESCO in 1997. Unusually, some volumes of the Annals were treated by beeswax for the permanent preservation. However, the examinations on the deterioration of the beeswax-treated volumes had been exposed the serious damage than the untreated volumes. In particular, the larger amount of beeswax were worst in deterioration condition. In order to solve these problems, NRICH(National Research Institute of Cultural Heritage) of Korea launched the investigation study for the conservation of beeswax-treated volumes of the Annals. Now then, the five study areas have been set up; 1) to understand the damaged condition of the Annals; 2) to analyse the raw materials and production techniques; 3) to test the degradation degree using the duplication samples for understanding the aging factors and mechanism; 4) to develop the conservation techniques through dewaxing and thereafter strengthening the base paper of Hanji; 5) to develop the long-term storage technique using inert gases. On the basis of outcomes from this study, NRICH will plan to establish the systematic conservation and management plan for the beeswax-treated volumes of the Annals in future.

In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

In this study, the momentum conservation type punching mechanism for micropunching system was developed to avoid the punch failure in the misaligned status between the punch and die. The punching energy can be precisely controlled by the falling height of the projectile mass and the intermediata mass, which contacts with the punch, transmit the energy to the punch with the same contact condition. The potential energy of the projectile mass is converted to kinetic energy at the light weight punch that the projection speed into the sheet metal workpiece can be accelerated. The butt formation characteristics for the alignment condition and for the projection speeds are investigated to verify the feasibility of the proposed punching mechanism.

This report is researched on the cause and mechanism of soil erosion in comparison among Kwangnung, Mt. Kaya, Mt. Chili, and Mt. Soorak by physical and chemical analyses of their for- est soils. Clay, silt, and fine sand of Mt. Soorak are far less than those of Mt. Chili, Mt. Kaya, and Kwangnung area while coarse sand is very high level. The clay ratio of soil at Mt. Soorak is the most high level in comparison with that of other area. Denudation at Mt. Soorak, therefore, is cause of erosion by the result of transportation of soil particles. The eroding velocity increase for larger particle size and stronger cohesion between soil particles. Very fine sand, silt, and clay can be present in suspension near the bottom and the size of the particles in suspension depends upon the velocity of the current near the bottom and the roughness of the bottom. Key words: Theoretical analyses, Soil erosion and conservation, Forest soils.
