The purpose of this study is leading to reduce the setup time and cost of the ground telemetry system for FA-50 program. And using the accumulated experience during T-50 and TA-50 development period, remove the risk of development and construct the optimal ground telemetry system for FA-50. For this study, collect the ground telemetry data of the T-50/TA-50, analyze the data and problems and then suggest the optimal telemetry ground system for FA-50.

WRC-2000 adopted the Regions 1 and 3 BSS and associated feeder-link Plans as well as the Regions 1 and 3 BSS and associated feeder-link Lists. These Regions 1 and 3 BSS and associated feeder-link Plans provide, in general, each country of Region 1 with 10 digital channels of 27MHZ bandwidth and each country of Region 3 with 12 digital channels of 27MHZ bandwidth. In this study, we summarize the results of associated meetings and analyze the effects of BSS replanning in Korea. We study the effective interference analysis through the review of Radio Regulations and associate Resolution. Furthermore, interference analysis of inter-broadcasting satellite systems will be done with MSPACEG S/W.

This result of the study on the costume of Osman Turkey are as following. 1. Empire of Osman Turkey(129∼1922) exerted an almost limites impact and influence on Europe and Asia during their regime 600 years. The distant ancestors of the Osman Turks were nomadic peoples, who wandered I tribal groups through the Central Asia. Therefore their costumes were based on nomadic culture. They had trade with West and East were influenced by Hellenism and Byzantium and grew, to a strong Islamic political power polygamy with which influence their clothing along with other culture. 2. Topkapi Saray was one of he principal residences of the Osman sultans and his court. Late 17 century, Topkapi Saray found many of kaftans of Osman Turks Empires of 14∼17 centuries. Otherwise we studied by the minatures of 16∼17 centuries, Since the Topkapi Saray became a museum in 1924, a program of careful restoration has made it possible to some pars of it to the public, after centuries neglection. 3. Osman Turkey Empire had important role in between West and East(silk-road). Economic, commercial, social and political factor of Turkey led to a development in the art of weaving (kema, kadife, catman, seraser, zerbeft, hatayi, kntnu, atlas)parallel to the rise and development of the Osman Turkey Empire itself, one which raised the art to a level attained nowwhere else in the world. Fabrics woven from gold and silver thread occupied a very important place in the court life of the time. This was due as much to their symbolic as to their material value, reflecting as they did the power, glory and magnificence of the Empire. 4. In order to study Eastern or Western history of costume one must study Turkey history of costume in advance. Also there is a great need of comparison to study of western, central and north eastern area history of costume.

The Great War of 1914-1918 had dramatic consequences for all aspects of European society. Academia, and the field of mathematics, was no exception to the changes which occurred following the conflicts conclusion. After the First World War, which left Germany, the Austro-Hungarian Empire, Bulgaria and Turkey defeated, the Treaty of Versailles imposed harsh revisions to the old order. Many new nations emerged and the map of Europe was redrawn. The victorious powers also created the International Research Council (IRC) in 1919, and the International Mathematical Union (IMU) was founded under the IRC' s umbrella in 1920. At that time Germany, Austria, Hungary and Bulgaria were excluded from participation and the IMU maintained an open anti-German policy. However, as time passed this policy became more sharply criticized and in 1928 ICM, the nonparticipants were invited to join. Having declined, controversy persisted until in 1931 the IRC was replaced by the International Council of Scientific Unions, and the IMU disappeared for over two decades until it was reestablished in 1951. During the time of the first tenure of the IMU it is argued by many that politics entered into the world of international mathematical cooperation. In this paper we study the real effects the Great War had on the international mathematical community and its mathematicians.
