러시아 극동지방으로의 한인 이주와 카자크족: 상호관계의 역사
세르게예프 ( O. I. Sergeev. ) 한국민족운동사학회 2005 한국민족운동사연구 Vol.42 No.-
The year 2004 was a commemorative year in the history of not only Koreans in Russia but also Cassacks in Far Eastern area. In 1864 Koreans began to move and settle around Russian frontiers, and 115 years ago Cassacks in Usurisk Province, as an independent structure separating from military corps stationed nearby the river Amur. With history, two peoples began to contact each other, and their mutual relation came down to the end of the 20th century. The history of the mutual relation between two peoples in Far Eastern Province can be divided into three phrases. The first phrase includes the period from 1860s to 1917, in which their relation was formed in the process of cultivation and settlement of a large wasteland incorporated in Russian territory. The second phrase is from 1917 to the end of 1930s. After the February Revolution, Korean society recovered activity. But land reform by the Soviet authorities soon made Koreans fall into a difficult situation which applied to the Cassacks. After Koreans and Cassacks together met adversities by the Soviet power. The mutual relation between Koreans and Cassacks during the period from the end of 1930s to the beginning of 1980s can not be thought. Because during this period there were no meaningful mutual relations. The Third phrase covers from 1980 to the present. During this period their mutual relation gradually began to appear in accordance with the changing of Soviet society. After the compulsory immigration in 1937, Korean inhabitants in the Central Asia had to endure tolerable agony and suffering, but could overcome such difficulties by the exceptional diligence and fraternal love of Korean. Cassack society in Far Eastern province also from the end of 1980s began to be revitalized because they rapidly adapted themselves to the national public system.

The processes of obtaining a new type of ceramic proppants with high physical and mechanical propertiesbased on serpentinite rocks, which were not previously used for this purpose are investigated. Toincrease the strength of ceramic materials, methods of improving the sintering of magnesia-silicateceramics with a forsterite crystalline phase are considered. It was found that the activation of the sinteringprocess is provided by the transformation of hard-to-sinter forsterite into enstatite. This is possible byadding of siliceous raw materials with different reactivity (quartz sand, marshalite, gaize and diatomite)to the pre-calcined serpentinite. The use of diatomite and gaize additives in an amount of 20–30% insteadof quartz sand allows to reduce the firing temperature by 50–70 C (from 1300–1350 C to 1280 C–1250 C) and ensure the mechanical strength of pressed specimens up to 440 MPa. This made it possibleto develop compositions and technological parameters for obtaining magnesia-silicate proppants witha bulk density of 1.58–1.62 g/cm3 at a firing temperature of 1250–1300 C, capable of withstandingbreaking pressure up to 52 MPa.

The first experiments on observation of amplification of ultrashort microwave superradiance (SR) pulses under propagating along quasistationary electron beams were performed. For this purpose experimental set-up based on two high current accelerators RADAN synchronized with accuracy 100-300 ps was build up. The first accelerator was used to drive the 37 GHz generator of superradiance pulses with duration ~300 ps based on relativistic BWO. The second accelerator with current up to 1.2 kA and electron energy ~300 keV drives the amplification section in the form of dielectric loaded waveguide. According to theoretical analysis amplification of electromagnetic pulses (minimum in 4 times on power) was accompanied by significant shortening of SR pulse duration fewer than 100 ps.

The influence of the hydrostatic pressure P up to 0.95 GPa on the excess conductivity s0(T) and the pseudogap D*(T) in optimally doped YBa2Cu3O7d single crystals (Tc x 91.1 K at ambient pressure) is investigated by electrical resistivity measurements. A pronounced enhancement of the pseudogap under pressure of dlnD*/dP z 0.32, which is only a factor of 1.12 smaller than in slightly doped single crystals, is revealed for the first time. This implies a somewhat more moderate increase of the coupling strength in optimally doped cuprates with increasing pressure. Simultaneously, the ratio 2D*(Tc)/kBTc z 5 at P ¼ 0 GPa, which is typical for high-temperature superconductors with strong coupling, increases by 16% with increasing pressure. At the same time, the pressure effect on Tc is minor: dTc/dP z þ0.73 K GPa1, whereas dlnr/dP z (17 ± 0.2)% GPa1 is comparable with that in lightly doped YBCO single crystals. This suggests that the mechanisms of the pressure effect on r(T) and Tc are noticeably different. Independently of pressure, near Tc, s0(T) is well described by the Aslamazov-Larkin (3D-AL) and 2D Hikami- Larkin fluctuation theories, exhibiting a 3De2D crossover with increasing temperature. However, the temperature interval Tc < T < T01, in which s0(T) obeys the classical fluctuation theories, is exceptionally narrow (z1.16 K). Nevertheless, a peculiarity at the temperature T01, up to which the wave function phase stiffness in the superconductor is maintained, is clearly observed in the dependence D*(T). Below T01 a fast growth of D*(T) is revealed for the first time. It can be associated with a sudden increase of the superfluid density, ns, that is the density of fluctuating Cooper pairs (short-range phase correlations) forming in the sample when T approaches Tc.
