When the unification process was established, West German librarians formed a commission for all library and information sectors. After legal unification, the committee formed 6 Arbeitsgruppe(AG) to develop library and information policies for the country. This was designed specially to elevate the level of the East German library system to the West German standard. The first AG concerns the public libraries. The second AG focuses on the education system for library and information specialists. The third AG examines the academic libraries. The fourth AG reviews the regional and national library services and the central organization. The fifth AG explores library and information techniques. The sixth and final AG inspects the legal problem of libraries. Each AG consists of specialists from both East and West German library systems who are experts in their particular subject area. The committee has general meetings to determine the best direction for the nation's library system. Common knowledge indicates this unification was based on economical amalgamation(fusion) from East Germany to West Germany. The unification resulted in the library and information recommendations tending to favor the more advanced West German policies. In this process there are a number of subtle ideological and psychological problems. If before the separation they had developed their library system as one entity, they could overcome the current differences. with much less confusion. In this political phenomenon we can learn that cultural unification needs more time than political unification.

In this study, datum points measurement have been collected and then weather data have been analyzed to figure out erosion and deposition environmental change around Halmi-island, Baramarae. First of all, it was difficult to analyze geomorphological change which is caused by climate change because of quite short term of collection period of data. However, differences in spatial distribution of erosion and deposition have locally been shown. In all season, the wind is blowing in north and north-west direction mostly except in summer which is shifted to south direction. However, since its ratio which are above 5m/s is much lower than the north and north-west wind, its effect on geomorphological process is very tiny. In order to look at a tendency of erosion and deposition environmental change around Baramarae Halmi-island, the periphery of Halmi-island was classified to east and west part, then accumulated erosion and deposition values have been calculated. As a result, generally, the datum points are located in the west part which are mostly depositional sites. On the other hand, the datum points are located in east part showed the dominant erosion patterns.

Gamcheon Bay has complicated and unique flow pattern which is affected by topography characteristics of a semi-closed bay and warm water discharge from the power plant located at the bay. It is very important to consider warm water discharge with tidal period and wind effects, which are mainly acting on the surface flow patterns in Gamcheon Bay. The results of observation show as follows; i) Because Gamcheon bay has much elongated shape to the north-south direction and narrow entrance with two separated breakwaters, the flow is very weak inside the bay. ii) The main flow path is at the west side of the bay. The direction of flood current is northward along the west side of the bay and the direction of ebb current is southward along the west side of the bay. The southward direction of warm water discharge has curved to the west side of the bay. iii)At the period of flood current for neap tide, the flow direction is southward in the bay, which is thought by the effects of warm water discharge. But at the bottom layer, the effects of tidal current reached to the middle of the bay, and showed features like eddy. iv) The wind effect is very strong, especially, prominent in the west and east side of the bay.

This paper focuses on GPS positioning accuracy variations according to locations of obstacles which surround GPS station. We derived precise coordinates of a GPS station which has a good visibility. Its observation data was rewritten by assuming signal blocking due to obstacle in the elevation angle of $10^{\circ}$ to $70^{\circ}$. We processed daily and hourly data for 10 days. In the results using daily data, RMSE was at 10mm level. And RMSE increased to 100mm levels in case of hourly data. As the elevation angle of obstacle increased, the horizontal and vertical RMSE increased, while the height estimates decreased. These results showed the higher the elevation angle of the obstacle increased the loss of large amounts of data by blocking satellite signals direction. In terms of the direction, when the blocking thing was located in the east or west, the coordinate has larger error in the east-west direction. And if signal was blocked at the south direction, the difference between the east-west error and the south-north position error was reduced.

Kinematic global positioning system precise point positioning (GPS PPP) technology is widely used to the several area such as monitoring of crustal movement and precise orbit determination (POD) using the dual-frequency GPS observations. In this study we developed a kinematic PPP technology and applied 3-pass (forward/backward/forward) filter for the stabilization of the initial state of the parameters to be estimated. For verification of results, we obtained GPS data sets from six international GPS reference stations (ALGO, AMC2, BJFS, GRAZ, IENG and TSKB) and processed in daily basis by using the developed software. As a result, the mean position errors by kinematic PPP showed 0.51 cm in the east-west direction, 0.31 cm in the north-south direction and 1.02 cm in the up-down direction. The root mean square values produced from them were 1.59 cm for the east-west component, 1.26 cm for the south-west component and 2.95 cm for the up-down component.

This study investigated the dimensional plan of Kor Sork temple in Preah Pithu complex, Angkor by civil surveying, 3D scan, measured integer ratio and regularity. According to epitaph and preceding researches, Khmer temples were built based on structural planing with the constant ratio and regularity by using special construct measure scales "Hasta" and "Byama". The study assumed the same unit method was applied in Kor Sork temple and identified the regularity of actual measurement value about the temple. The assumed construct measure scale (Hasta) used for the design of this temple is 413mm. The overall apart arrangement of the temple is different in the East-West direction and the North-South direction. In the East-West direction, the whole scale is 180 hasta, and it is divided into 20 hastas. On the other hands, it was confirmed that the North-South direction is 96 hasta and it was divided four quadrants in 24 hastas. Regarding the detailed design, the regularity according to the constant ratio was confirmed. 7 hasta was used as the basic unit on the first floor and 6 hasta were used as the basic unit on the second floor of the terrace. the basement and the central sanctuary is of 6 hasta and 8 hasta were used as the basic standard.

This paper attempts to rethink the ancient Emperor's Capital transition process from the viewpoint of territorial history. Emperor Tenmu, who planned first capital as Fujiwara-kyo in Asuka region, had a grand plan to put multiple cities in Japan. At that time the important cities were situated along east-west axis. However, since relocation of the capital from Fujiwara-kyo to Heijyo-kyo, the axis had turned towards north-south direction. The last ancient capital Heian-kyo was clearly organized utilizing north-south water systems in territorial sense.

In contemporary modern architecture, it can be said that Western modern architecture, which has advanced in technology and ideology, is leading the world architecture today. However, because it is pointed out that modern architecture, mainly represented by Western architecture nowadays, is based on the crystal of Western civilization's consumption and capitalist culture, and because it seems not absolute for the eternal sustainable development of the Earth and happiness of Humankind, it is assumed that the new conceptions of Architecture should include the cultural, ecological and environmental characteristics of the region. So because it is thought that the latent characteristics of East Asian architecture including China, Japan and Korea has the advantage of reducing the deficiency of Western modern architecture and contributing to human civilization, this study was written to find a new direction of architecture by finding the differences of architectural characteristics(intrinsic and extrinsic) in the interior of the architectural result through comparison between the Eastern and Western architecture.

This study is to analyse the transformation process of spatial structure of traditional small city structure in Jeollabuk-Do in the process of modern urbanization between 19th century and the year 2000. The small cities, IM-PI, YONG-AN, YEO-SAN, OK-GOO, GO-SAN, MU-JANG, GUM-MA, GO-BU, which have been local administrative center in CHO-SUN dynasty, have role of local administrative center of subdivision of country-myon, except OK-GOO. The method of this study is to investigate the transformation process of spatial structural elements of with the actual field surveys, the analysis of Gunhyun map made in 1872, land registration maps in 1910s and 2000, and various topological maps. The elements of analysis are the topological site and geographical situation conditions, the urbanized areas, the street systems, the function of streets, the focal points of urban land use, the land use systems, and the location of major facilities such as administration facilities, markets, bus terminals. The analytical point of view and the results are as follows. There is strong relationship between the transformation of internal matrix route system and the growth pattern of urbanized areas, Especially on the contrary to the matrix route with East-West direction which has the role of checking the growth of urbanized area, the South-North direction route acts as the leading line of the growth. The focal points structure of urban land use shows transformation process from the point of central space of administrative district in front of Nae-A, to the access point to administrative district or to the access point to housing and neighborhood commercial area. From the point of functional area structure and major facilities location, line-type commercial area is developed along the line of central axis route and access route to administrative district. Especially direction of the growth of commercial area is strongly connected with the interrelationship between the study area and its neighboring cities. Pattern of commercial district development is varied with the direction of matrix route. That is, commercial district, which shows one side development pattern along the East-West direction route, is developed on both sides of street along the South-North direction route.

Variations of mean ionospheric spatial gradient over Korea are analyzed in order to support GNSS (Global Navigation Satellite System) augmentation systems and integrity monitering systems. A software for analyzing the ionospheric spatial gradient is developed using an ionospheric plate model. Daily and annual variations of ionospheric delay and spatial gradient are analyzed using GPS data in 2003 and 2005 respectively. The ionospheric delays and spatial gradients in 2003 were larger than 2005. Also, the south-north gradient, about -1.0mm/km, is nearly two times larger than the east-west gradient. The annual ionospheric spatial gradients over Korea is varied within 2mm/km.
