Mineral composition and chemistry of the clay minerals in the three cores from the continental shelves of South Shetland Islands (NCS09) and Anberse Island (GC98-2), and from the fjord of King George Island (A10-01) were determined by X-ray diffraction and electron microprobe analysis in search of the distributions and origin of the clay minerals in the Antarctic marine sediments. Smectite content is relatively high in NCS09 regardless of core depths (av. 8.3%), but low in GC98-2 (1.1%). In Al0-01, smectite content is higher in the upper section than in the lower section. Kaolinite was not detected from all the cores in this study Yellow to yellowish green clay granules were commonly scattered in the sediments of NCS09 cores. The clays contain 16.97% and 2.53% $Fe_2$$O_3$와 $K_2$O. Average structural formula of the clay indicates ferrian beidellite . The (Fe, K)-rich smectite of NSC09 must have been derived from relatively young basaltic volcanics altered by reaction with seawater near Shetland Islands by glacial erosion or eolian process related to volcanic eruption. GC98-2 nearer to Antarctic continent is very low in smectite content. In A10-01, the lower diamicton was deposited from the glacial erosion of smectite-free ancient volcanics in the interior of King George Island, while the upper section was derived from the smectite-bearing terrestrial debris and eolian materials after retreat of glaciers in Marian Cove and ice cover in Barton Peninsula. Thehigh K contents of smectites suggest the interstratification of illite and smectite layers, which might be observed by future TEM lattice fringe imaging.

These days, beds have been developed not as furniture to sleep in but Healthcare Furniture. The function of heating, non-electronic-waves and far-infrared rays have been added. Also, eco-friendly materials such as stone, mud, rubber and wood are combined to them together with the radiation-heating method using heat conduction through electronic coil and hot water circulation. Modern people suffer from stress and fatigue. The hot issue is "health." Focused on the health, the development of design for beds considering the influence electronic waves, anions, deep sleep and the density of toxic materials have on human bodies has become urgent. In this study, the trend, specification and efficiency of the functional health-related electronic coil technology are analyzed. Through the analysis, the environmental standards are set. According to them, technology, eco-friendly materials and additional functions for the development of the design are considered. Also, the government is promoting the IEC international standardization for the Korean traditional floor heating style beds. In preparation for that, we adopted new HPT method technology. It enables non-electronic-waves, low electricity and stable temperature maintenance control for the warm top and the cool bottom. Also, the head boards and the frames of the beds can be separated. Through this separation, the beds can be easily moved or installed. Eco-friendly materials such as Hinoki cypress wood and red clay and the existing tables function are combined to the head boards so they can be used as drawers and display shelves. If they are used as separate items, they can be used as covers. This is how we suggest the design for the heating beds.

The objective of this study is to understand the application of relative location system and minute classification system in the DDC and to identify the effect of the relative location system and minute classification system during the late of 19th century. In order to achieve the objective, four main investigation areas were chosen: relative location system, minute classification system, and DDC influence to other libraries and classification systems. First, DDC applied a relative location system revolutionarily instead of a fixed location system for arranging books on the shelves, so it opened the period of modern library classification systems. Second, it used a minute classification system, and could classify books which had minute subjects. Third, it applied form to a criterion for dividing divisions and sections, so it helped for classifying books. Fourth, it used a numerical decimal system as a classification system, then people could use it economically and practically. Last, DDC influenced modern classification system such as the Expansive Classification and the Subject Classification etc. DDC is a suitable library classification system for the needs of the times, and it is a practical classification system for each library.

On 25 December 2000, China and Vietnam signed the Agreement on the Delimitation of the Territorial Seas, EEZs and Continental Shelves in the Tonkin Gulf. Three and a half years after signature, in June 2004, China and Vietnam both ratified a maritime boundary agreement for the Tonkin Gulf (Beibu Gulf) and the agreement entered into force. A potentially complicating factor in the negotiation process was likely to have been the status of the Sino-French Agreement of 1887. In the end, the agreement reached indicated that even if the status of the Sino-French Agreement of 1887 was part of the negotiations, both sides eventually agreed that it would not have an impact on the delimitation of maritime zones in the Gulf of Tonkin. Another crucial issue was the impact of the islands, in particular, the Vietnamese controlled Bach Long Vi Island and Con Co Island. Especially, Bach Long Vi Island was entitled to a half suite of maritime zones (3n.m. EEZ) and would impact the tracing of a line of equidistance in the Gulf of Tonkin. Minor as the point might be, Con Co Island also would have an impact for it would play a fixing terminal point for the boundary. Article 7 of the agreement is about minerals and hydrocarbons of cross-boundary deposit, and if any single geophysical structure of oil and gas or other mineral deposits should straddle the demarcation line, an agreement is to be reached on the development of the structure or deposit and on the most effective manner to equally share the profits resulting from the development.

An Apartment Veranda is a transitive space which is being used for many different purpose. A Rear Veranda which is connected to the kitchen is an important space for the housekeeping work and it should be planned carefully to reflect the rational and functional designs. Therefore the objective of this research is to suggest a systematic basis for the practical space planning of the Rear veranda that meets the varied needs of consumers by examining its usage pattern through the analysis of the apartment occupant's behavior pattern stored item the degree of satisfaction and consumer requirements. The research was conducted mainly on apartments built after 1990. The following are the conclusions from the research : 1. Most of the research respondents were aware of the absolute need for the Rear veranda. But they expressed dissatisfaction with the space usage. This indicates that the Rear Veranda planning does not reflect the functionality of the space and concentrates on the idea of providing consumers a service space based on the size of the apartment instead. 2. Although the Rear veranda is used as the multipurpose housework space it is mainly used as the laundry and storage space. This shows a big deviation from the concept of the utility space. Because the behavior pattern associated with the Rear Veranda is largely influenced by the traditional life pattern the development of the Rear Veranda as an exclusive space for the housekeeping work. 3. According to a high frequency of the storage of the laundry related item in the Rear Veranda indicated by the research the Rear veranda is used as the laundry room as well as a auxiliary storage space by most people. The installation of gas range is expected to increase due to the expansion of the usage function of the Rear Veranda space. The installation of a specialized refrigerator to store the traditional food is demanded. 4. Consumers need more efficient and functional storage device because the temporary shelves are often being used as the storage device. The perception of the storage device is assumed to have been influence by the traditional life style.

This study was conducted under the premise that the university library's subject specialization room is in need of major modifications in order to accommodate the needs of various majors. The subject specialization room will be able to support university library users who are inclined to use the general reading room. Therefore, the study presents spatial planning for the average university library's subject specialization room by taking into account student majors. This could be a guideline for the construction and renovation of university libraries in the future. The summary of results for this study and the conclusions are as follows: 1)Natural sciences subject specialization room should be, partially connected with the humanities/social science subject specialization room in order to provide an open-concept reference room. In the shared area connecting the two subject specialization rooms needs to be installed a staff counter and subject specialist librarian service booth for users of both subject specialization rooms. 2)For humanities/social sciences subject specialization room, partially connect with the natural sciences subject specialization room. In the connecting area between the two rooms, plan an open-concept lounge for resting and reading. 3)It is best to plan subject specialization room for art/music/physical education majors separate from the subject specification room of other majors. Structurally separate art/music/physical education major subject specialization rooms from the building or plan a separate room in an art/music/physical education building. Users of art/music/physical education majors showed a high preference for a spatially separated and specialized library structure, which proves that an art/music/physical education library need to be planed based on the specialized library structure found in law school libraries or medical school libraries. Plan the center of the room with open-concept based reading room. Use wall-sides, partitions, or shelves to create reading space separate from the shelving area.

The purpose of this study was to investigate spatial characteristics and using behavior of activity room in skilled nursing facilities for the elderly and to provide basic guidelines about its space planning. The activity rooms in the most of the research facilities were arranged by usage modification of unnecessary spaces after the foundation of the facility, and were used not only for the program service but for the staff lounge. It decreased space speciality and resulted in limited area of the space and crowded furniture arrangement. The design guidelines for activity room were as follows. First, the space plan of activity room is based on the use of once to twice per week and for 30 minutes per use, and is mainly for the human knowledge and art programs that are appropriate for small group. Second, the activity room of the facility with less than 3 stories needs to be in the same floor as elderly individual room, but should be independent and easy to be controlled by the staff. On the other hand, in more than 4 stories facility, it is better to be in the different floor as the elderly living area such as administrational area close to the lounge and garden. Third, at least $5.9m^{2}$ per user for the area of the activity room is recommended including the elderly, staff, furniture, equipments and restroom. Fourth, the furniture of activity room includes the shelves, big table with enough knee space, wheel, and stopper, and stackable chairs. Toilets and water closet are needed for the emergency, and the windows to the corridor and curtain door should be avoided for soundproof and easy access of wheelchair users.

Purpose: This study was conducted to analyze the air flow characteristics in a plant factory with different inlet and outlet locations using computational fluid dynamics (CFD). Methods: In this study, the flow was assumed to be a steady-state, incompressible, and three-dimensional turbulent flow. A realizable k-${\varepsilon}$ turbulent model was applied to show more reasonable results than the standard model. A CFD software was used to perform the numerical simulation. For validation of the simulation model, a prototype plant factory ($5,900mm{\times}2,800mm{\times}2,400mm$) was constructed with two inlets (${\Phi}250mm$) and one outlet ($710mm{\times}290mm$), located on the top side wall. For the simulation model, the average air current speed at the inlet was $5.11m{\cdot}s^{-1}$. Five cases were simulated to predict the airflow pattern in the plant factory with different inlet and outlet locations. Results: The root mean square error of measured and simulated air current speeds was 13%. The error was attributed to the assumptions applied to mathematical modelling and to the magnitude of the air current speed measured at the inlet. However, the measured and predicted airflow distributions of the plant factory exhibited similar patterns. When the inlets were located at the center of the side wall, the average air current speed in the plant factory was increased but the spatial uniformity was lowered. In contrast, if the inlets were located on the ceiling, the average air current speed was lowered but the uniformity was improved. Conclusions: Based on the results of this study, it was concluded that the airflow pattern in the plant factory with multilayer cultivation shelves was greatly affected by the locations of the inlet and the outlet.

At present, the time of easy oil and gas is over. Now, the largest part of fossil fuels is concentrated in the deepest levels of tectonic structures and in the sea shelves. One of the most cumbersome operations of their extraction is the bore-hole drilling. In connection with austere tectonic and climate conditions, their drivage every so often is associated with great and diversified technological difficulties causing emergencies on frequent occasions. As a rule, they are linked with drill string accidents. A key role in prediction of these situations should play methods of theoretical modelling. For this reason, there is a growing need for development and implementation of new numerical methods for computer simulation of critical and post-critical behavior of drill strings (DSs). In this paper, the processes of non-linear deforming of a DS in cylindrical cavity of a deep bore-hole are considered. On the basis of the theory of curvilinear flexible rods, non-linear constitutive differential equations are deduced. The effects of the longitudinal non-uniform preloading, action of torque and interaction between the DS and the bore-hole surface are taken into account. Owing to the use of curvilinear coordinates in the constraining cylindrical surface and a specially chosen concomitant reference frame, it became possible to separate the desired variables and to reduce the total order of the equation system. To solve it, the method of continuation the solution by parameter and the transfer matrix technique are applied. As a result of the completed numerical analysis, the critical states of the DS loading in the cylindrical channels of inclined bore-holes are found. It is shown that the modes of the post-critical deforming of the DS are associated with its irregular spiral curving prevailing in the zone of bottom-hole-assembly. The possibility of invariant state generation during post-critical deforming is established, condition of its bifurcation is formulated. It is shown that infinite variety of loads can correspond to one geometrical configuration of the DS. They differ each from other by contact force functions.

The most important two decision-makings which a retail store owner face require which place of the store should geographically be established and which stock should be properly placed on the shelves. The problem of geographic positioning is the decision-making for the store's positioning and stock arrangement within the retail store is the decision-making for the placement store. In order to determine the positioning, the expected area should be analyzed so that the analysis of commercial area can usually be implemented in accordance with retail marketing strategy and therefore the sized of the potential market for example each distric's clientele, competition and, a municipal community's regulations, could be evaluated. But I contend that with only the size of potential market does not give an adequate answer to the problem of a store's positioning. Through the estimation of commercial are in combination with feng-shui, the theory of divination based on topography, the store's position could be selected, taking a positive energy, Gi. This thesis is the starting point of these trials. In the long run, the actual analysis of the study should be continued in a more scientific, systematic, statistical way.
