Recently, research and commercialization related to the field of cell-based therapeutic drug development has been actively conducted. In order to maintain cell viability and prevent contamination, refrigeration preservation devices, such as CRF (controlled rate freezer) or vapor type LN2 tanks have been developed. On the other hand, the storage container for liquid nitrogen tanks currently on sale minimizes the flow structure to prevent structural defects when stored in a liquid nitrogen tank having a high thermal conductivity than vapor nitrogen. If the cell-based treatment drug is stored in the gaseous LN2 tank as it is, the cell survival after thawing is greatly reduced. It was estimated that the existing storage container structure was a factor that prevented the rapid entry and circulation of gaseous nitrogen into the container. Therefore, this study intends to propose a new supercellular storage container model that can maintain the mechanical strength while maximizing the fluid flow structure. To this end, we estimated that the structural change of the storage container effects on the equivalent stress formed around the through-holes of them when exposed to a cryogenic environment using thermal-structural coupled field analysis. As a result of storage experiments in the gas phase tank of the cell-based therapeutic agent using the developed storage container, it was confirmed that the cell growth rate was improved from 66% to 77%, which satisfied the transportation standards of the FDA(Food and Drug Administration) cell-based therapeutic agent.

This research aims to establish the size standard of university library's user space, and present the standard and method to calculate total area required in the planning of new building construction and remodeling. Nine university libraries newly constructed or remodeled since 2000 were selected among the libraries of large scale universities with more than 10,000 enrolled students as the target libraries in this research. The target libraries were classified into A group (five cases partially remodeled) and B group (four cases newly constructed or fully remodeled) on the basis of the change of times. A university library can be divided into three spaces (user space, administration space and public space). This research classified the reading room in the user space into bookshelf zone, reading zone, information/office zone and hall/other zone, and analyzed area ratio according to each zone. B group's bookshelf zone decreased 12% more than A group, and B group's reading zone increased 10% more than A group. However, there was no big change in the area ratio of information/office zone and hall/other zone. This can be interpreted that university library changes from book and archive preservation-oriented space to user-oriented space. This research presented a proper reading room area calculation method, based on the capacity of books, by reflecting such a change. Each zone's standard was set up through classification of domestic and international standards, based on which, the calculation method of university library's total floor area required was presented. The reason why there was difference in university library's total floor area required according to domestic standard and international standard was that the number of enrolled students per seat in the reading room was different. The area calculation methods presented in this research can be utilized as useful data upon planning university library construction or remodeling.

Objective: Ensiling is a simple and effective method for long-term preservation; however, less information exists about the ensilability characteristics of garlic stalk (GS). Therefore, the objectives were to examine the ensiling feasibility of GS. Methods: The GS was ensiled alone or inoculated with Lactobacillus plantarum KU5 in the presence or absence of 5% molasses and ensiled for 7, 14, and 28 d. As an alternative storage method, GS was co-ensiled with wet citrus pulp (CP) at different proportions (GS:CP: 70:30, 60:40, 50:50, and 40:60). Analysis was made on physicochemical, fermentative, and nutritional parameters. Results: The GS was found to be a biomass which is difficult to ensile. A combination of microbial inoculant and molasses was successful in the improvement of the silage fermentation quality of GS. Co-ensiling of GS with wet CP at the mixing ratio of 50:50 provided the most desirable silage fermentation parameters, including the substantial lactic acid formation, low final pH, minor effluent loss, and the more favorable organoleptic properties. Conclusion: Co-ensiling GS with CP appears to be a simple and viable method of conservation, enabling the more efficient utilization of these by-product resources over a prolonged period.

Objectives: The purpose of this in vivo study is to observe anti-amnesic effects of Yeongkyekamjotanggayonggolmoryo (YGYM), a novel mixed herbal prescription, Ossis Mastodi and Ostreae Testa added Yeongkyekamjo-tang, on scopolamine induced amnesia in C57BL/6 mice through acetylcholine (ACh) and acetylcholinesterase (AChE) activity, Choline acetyltransferase (ChAT) mRNA expression, and antioxidant effects. Methods: Six groups, total 20 intact or 100 Sco treated mice were used in this study after one week of acclimatization period. Half the animals were used for passive avoidance task tests and hippocampus ACh content, AChE activity, and ChAT mRNA expression were measured. The other half was subjected to an underwater maze test and then the cerebral cortex antioxidant defense system was measured. Results: In the passive avoidance experiment, there was significant decrease in residence time in the bright room and in the underwater maze test, escape latency to escape from the esophagus significantly increased compared with the normal control group. At the final sacrifice, ACh content and ChAT mRNA expression decreased, AChE activity increased, and cerebral cortical MDA increased GSH content, SOD and CAT activity in Sco control mice, as compared to intact vehicle control mice. However, these Sco treatment-related memory loss through AChE activation destroyed the cerebral cortex antioxidant defense system, and was inhibited dose-dependently by 28 days consecutive oral pretreatments of YGYM extracts 500, 250, 125 mg/kg. Conclusions: In the above results, YGYM extract that oral administration of YGYM extracts alleviates the antioxidant defense system, through preservation of ACh mediated by upregulation of ChAT mRNA expression, and increase of AChE inhibition and brain antioxidant defense systems.

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 Mural Tomb of Xu Xianxiu(AD 571), a high ranking official in Northern Qi period, is located in Taiyuan, Shanxi province, China. Despite having been raided, it was still discovered to contain over 530 pieces, such as artifacts and murals, in excellent state of preservation. These murals are noteworthy for their high level of detail compared to other murals from the same era, and are important for understanding the historical context of active East-West and Han-Hu cultural exchange in the $6^{th}$ to $7^{th}$ century. The murals of Xu Xianxiu's tomb depict round-collared and narrow-sleeved garments as well as straight collared robes typical of the Xianbei tribe's attire. Notable are the ermine fur overcoat and a headwear with flares on the left and right thought to be unique to the Xianbei. The wife and female servants show female attire of the Xianbei at the time; this attire can be characterized by narrow-sleeved long gowns and asymmetrical flying-bird buns. Despite the anti-Han policy of Northern Qi, influences such as the right sided gathering of the robes and embellished hair styles remain. The procession also depicts the three-cornered headdress and long-tailed hood of the Xianbei men, which have been recorded in documents. The large rounded pearl pattern containing the palmette, the divine animal, and bodhisattva's head motifs show the influence of the Western China [Xi'yu]. Considering that Northern Qi had more active interactions with the three ancient kingdoms of Korea than with the Southern Kingdoms[Nanchao], the findings of this study call for further research on the correlation between the attire of ancient Korea and Northern Qi.
