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 STELLA program was launched to support the PGSFR development in 2012 and for the 2nd stage, the STELLA-2 facility was designed to investigate the integral effect of safety systems including the comprehensive interaction among PHTS, IHTS and DHRS. In STELLA-2, the long-term transient behavior after accidents can be observed and the overall safety aspect can also be evaluated. In this paper, the basic design concept from engineering basis to specific design is described. The design was aimed to meet similarity criteria and requirements based on various non-dimensional numbers and the result satisfied the key features to explain the reasoning of safety evaluation. The result of this study was used to construct the facility and the experiment is on-going. In general, the final design meets the similarity criteria of the multidimensional physics inside the reactor pool. And also, for the conservation of natural circulation phenomena, the design meets the similarity requirements of geometry and thermo-dynamic behavior.

The National Park should be preserved as described in the regulation. However, the development has resulted in degrading the environment in the park. Especially, the collective facility area has been developed for the commercial benefit rather than for the preservation. So, it is necessary to figure out the impact of the development plan proposed. Thus, the purpose of this study is to explore the hydrologic effects due to the collective facility area development in the National Park. The study site is the second collective facility area of Mt. Kyeryong National Park. The analysis of hydrologic effects due to the development has been carried out using the GIS in this study. The Rational Method and Soil Conservation Service(SCS) were used to estimate the runoff volume. During this procedure, GIS software, ARC/INFO was used to integrate, manipulate, and calculate the attribute value of a number of ploygons which represen each land use characteristic. A program was written to compute the attribute value of each polygon and to estimate the difference of peaktime runoff volume before and after development.

Attempts were made to increase an efficiency of soil contamination investigation systems (SCISs) including Soil Network and Special Soil Contamination Management Facility Sites in Korea. In order to increase low efficiencies resulting from inappropriate SCISs, possible policy suggestions are driven based on the results from problem findings of Korean policy and comparisons of policies on industrialized countries including United States, United Kingdom, Germany, the Netherlands and Japan. First, functions of Soil Environment Conservation Act (SECA) on liability should be updated and reinforced to initiate a soil contamination investigation process for stakeholders including an owner(s) or a responsible party(ies) of the potentially soil contamination sites positively. Second, appropriate SCISs should be emerged for implementing the Soil Network and Special Soil Contamination Management Facility Sites properly. Stakeholders for the potentially contaminated sites should easily access and raise the soil contamination issues, and soil contamination investigation implemented by liable and profit environment (consulting) companies should be encouraged. Third, the soil contamination reporting system of SECA needs to change legally responsible. Further more, public announcement system showing soil quality of a site which exceeds a certain scale would be considerable. Fourth, liable environment (consulting) companies should legally execute Soil Environment Assessment of SECA.

Because the hospital building operates 24 hours a day, 365 days a year for treatment and restoration of patients, it has a different pattern of energy use than that of ordinary buildings. Hospitals contribute to energy consumption and have a negative environmental impact. This study aims to find how meaningful energy performance, reflecting good energy management and ECMs, can be operated for hospital buildings, a category encompassing complex buildings with different systems and large differences between them. In this study, we proposed the energy diagnosis & evaluation method and energy management process to verify energy saving through operation data based on system & facility characteristics, operation pattern and energy consumption characteristics of hospital building. Energy consumption structures were surveyed throughout 4 reference hospital in Seoul, Korea. Findings confirm that different hospital departments have hugely different energy-demand profiles. Energy efficiency and energy saving potentials are presented. The energy performance analysis can be applied to a wide range of problems in energy-system operation.

Hereupon, the results of this study are as follows. First, exhibition space should be equipped with sufficient 'Filtering Space' before the outdoor and located central territory in a museum facility. Second, exhibition space should be partition off an area into the quality of collection, and then controlled by each of them. Third, in consideration of the annual air fluctuation of our country, the database which is adaptable for setting up the standard of temperature and RH must be prepared. Fourth, it is necessary to establish a 'Reference Exhibition Room' which is formed cellular type and a 'Garnering Exhibition Center'. Fifth, for the prevention of deterioration which is generated in exhibition space, the showcase must be high air-tight. Sixth, it is necessary to reduce a inside space of high air-tight showcase. Seventh, art-sorb is suitable for control the organic matter of collection and a except of fiber optics is not suitable for lighting of showcase. Eighth, wall-type showcase should be have air-chamber which is formed like museum storage and run over 8 hours a day.

This study analyzes six slags excavated from the iron making site in Gogi-ri, Namwon, Korea to understand the characteristics of the ruins, and to confirm the iron making process performed at the time. The chemical components of the iron making by-products from the Gogi-ri site were analyzed, and the findings indicate total Fe contents between 23.24% and 37.56%, which are lower than the typical total Fe content found in ancient iron making processes. The deoxidation agent contents of the slags ranged from 43.88% to 58.13%, which are higher than the typical deoxidation agent content of ancient iron making processes. The high content suggests smooth separation between iron and slags, and TiO₂ detected from the site suggests the use of materials with high titanium content in the iron making in the region. As for the microstructures of the slags, some slags have long pillar-shaped fayalites, while others have pillar-shaped wüstite along with ulvöspinel. Slags from the forging furnace show hammer scales created by both the earlier stages and later stages of forging work. The findings suggest that the iron making site in Gogi-ri, Namwon, Korea used to be an iron making facility where a full range of iron making process was carried out ranging from smelting to forging, and the ironmakers used a wide array of technologies to manufacture iron products.

Seoul City built a facility for conservation of the Wongaksajisipcheungseoktap (Ten storied stone pagoda of Wongaksa Temple site, National treasure No. 2). It has speciality glass(thickness 21.5㎜) between steel-frames(8.4m, length 8.4m, height 15.4m). So we investigated the inside of facility to know whether the environment alvariation exists. We measured continuously the temperature and relative humidity, twice for the particulate, once for the $SO_2$(sulfur dioxide), $NO_2$(nitrogen dioxide)and $O_3$(ozone) from September $1_st$, 2000 to August $31_st$, 2001.The temperature and relative humidity, have a tendency to vary, and they have no difference between the inside and the outside. As dewy phenomenon doesn appear on the surface of the Pagoda and facility we know that the inside air is moving. As a result of the particulate is $64\mug$/$m_3$ of average concentration, the particulate fluxed inside don’t flow out because air-velocity of the outside is faster than that of the inside. The air pollutants are 0.036ppm/hr of SO$_2$average concentration, 0.028ppm/hr of $NO_2$ average concentration and 0.008ppm/hr of $O_3$ average concentration which are lower than the Environmental Air Quality Standards($SO_2$ : 0.15ppm/hr, $NO_2$ : 0.25ppm/hr,O3 : 0.1ppm/hr).

산성비가 대리석 문화재에 미치는 영향을 조사하기 위하여 1996년 1월부터 1996년 12월까지 원각사지 10층 석탑과 암질이 유사한 대리석 시편을 제작하여서 탑골공원과 광화문에서 옥외노출하여 직접 산성비를 맞게 한 경우와 광화문의 석탑보호시설내 산성비를 맞지 않는 경우를 비교하여서 부식감량을 조사하였다. 탑골공원과 광화문의 시편은 부식감량이 비슷하게 나타났으며, 또 비를 맞지 않는 실내에서 보다 7.7배 정도로 높게 나타났다. 또한 대리석 용해에 영향을 주는 산성비 특성을 연구하기 위하여 1~8 mm 강우에 대하여 이온성분 및 칼슘이온의 변화를 조사한 결과 1 mm 강우에 40% 이상 이온성분 농도, 특히 음이온 농도가 높았으며 칼슘 이온은 초기 1 mm 강우시 약 30% 이상 용출되었다. 이 결과는 초기 강우시에는 $SO_2$, $NO_2$등이 빗물에 녹아서 질산 이온, 황산 이온의 형태로 존재하게 되어 음이온 농도가 높게 된 것으로 판단된다. 대리석, 사암, 석회암으로 된 문화재나 미술품은 산성비 영향을 받을 수 있는 것으로 예상되어 향후 구체적 조사를 통하여 현장여건에 알맞는 문화재 보존대책 수립이 필요하다.
