  • The aim of this parasitological study is examining contemporary (the late 20th century) specimens of the arctic or subarctic areas in Western Siberia and comparing them with the information acquired from archaeological samples from the same area. In the contemporary specimens, we observed the parasite eggs of 3 different species: Opisthochis felineus, Ascaris lumbricoides, and Enterobius vermicularis. Meanwhile, in archaeoparasitological results of Vesakoyakha, Kikki-Akki, and Nyamboyto I burial grounds, the eggs of Diphyllobothrium and Taenia spp. were found while no nematode (soil-transmitted) eggs were observed in the same samples. In this study, we concluded helminth infection pattern among the arctic and subarctic peoples of Western Siberia throughout history as follows: the raw fish-eating tradition did not undergo radical change in the area at least since the 18th century; and A. lumbricoides or E. vermicularis did not infect the inhabitants of this area before 20th century. With respect to the Western Siberia, we caught glimpse of the parasite infection pattern prevalent therein via investigations on contemporary and archaeoparasitological specimens.

  • The interdecadal variation of wintertime blocking frequency over the Siberia ($60^{\circ}E-140^{\circ}E$) is examined using the ECMWF/NCEP-NCAR re-analysis data for the period 1958-2006. The wintertime blocking frequency over the Siberia significantly decreased for the period 1986-2006, compared to the period 1958-1985, which is mainly due to the anomalous circulation of 500-hPa geopotential height field. During the period 1986-2006, there was enhancement in both the anomalous cyclonic flow over the western Siberia and the anomalous anticyclonic flow over the east Asia. These anomalous circulation patterns, which might be associated with changes in surface temperatures over the Asian continent, are suspected to playa possibly important role as an obstacle to the formation of blocking flow over the Siberia.

  • An archaeoparasitological analysis of the soil samples from Nadym Gorodok site of Western Siberia has been carried out in this study. The archaeological site was dated as the 13 to 18th century, being characterized as permafrost region ensuring good preservation of ancient parasite eggs. Parasite eggs as Opisthorchis felineus, Alaria alata, and Diphyllobothrium sp. were found in the archaeological soil samples, which made clear about the detailed aspects of Nadym Gorodok people's life. We found the Diphyllobothrium sp. eggs throughout the 14 to 18th century specimens, allowing us to presume that raw or undercooked fish might have been commonly used for the foods of Nadym Gorodok inhabitants and their dogs for at least the past 400 years. Our study on Nadym Gorodok specimens also demonstrate that there might have been migratory interactions and strong economic ties between the people and society in Western Siberia, based on archaeoparasitological results of Opisthorchis felineus in Western Siberia.

  • Deprivation of means to study the cultures and history of the natives of Bering Strait in their own lands, gives us and especially U. S. A. and Russia-where the objective regions of this study is pertained to-the great suffering of intellectual and aesthetic losses. Throughout 20th century, as political and economic forces prevailed, it became increasingly difficult for both Natives and outsiders to see this region as having common past. In such difficult circumstances, United Nations Council for Environmental Development held at Rio de Janeiro, Brasil in June, 1992 started out to give obligations to present environmental future. With such trend getting stronger and being in demand, this study is also focussed on coincides with such environmental matters and differs from man centered western civilization which ruled th environment rather than to harmonize with it. Through the studies of fashions and cultural materials of this region, it was able to identify the great similarities between Northwestern Alaska and Northeastern Siberia. Especially in the clothing materials of this region\`s toy dolls, it was possible to confirm that both side of Bering Strait possessed similar culture. Although both side had similar environment, in the past its peoples began to be seen as separated and alienated aligned only with their current political state-Russia and U. S. A. Through this study, it was able to see diversity of the peoples and thir languages but also close cultural and historical ties that link them very closely together. This study verified such similarities and common characteristics through close examination of Native clothing and decorations and other traditions of Siberian Natives such as Yupik, Chukchi, Koryak, Even, Amur River peoples and Nivkh; and Alaskan Natives such as Inupiag, Yupik, Alutiig, Aleut, Athapaskan, and Tlingit.

  • Previously, studies concerning the Russian dialects have been mainly focused on northern, central, and southern dialects limited to western Russia of Ural Mountains. On the contrary, the Siberian and Far-eastern dialects have been completely disregarded to the main stream of the Russian dialectology. As a result of a poll concerning this idea, the majority has answered that there is no dialect in Siberian and Far-east regions. Though the reasons for the outcome of the poll could vary, it could not be simply accepted that there is no dialect in such vast regions. Thus, a survey has took place to examine the existence of dialects in the regions of Siberia and Far-east. The first phase of the survey inquired the residents of the regions including Siberia and Far-east to respond to questions regarding 83 vocabularies on wedding in contrast to the regions covering western Ural and Moscow. The 23 informants were residents of the concerned regions who have come to visit Pushkin National Institute of Russian Language and, others, Korea. The questionnaires used in this survey were partly obtained from the questionnaires originated by the Language Institute of St. Petersburg National University. Although the limited range of regions and a small number of respondents who partook in this survey could raise some issues on the table, it is relevant to understand that this study would open up the path for the development of studies concerning regional dialects in the future.

  • In order to develop a skin-whitening agent, melanin contents and intracellular tyrosinase activity were determined by western blotting. Ethyl acetate fractions of 80% ethanol extracts from lily (Lilium Oriental Hybrid 'Siberia') bulbs (R-EA) inhibited melanin synthesis in a dose-dependent manner in ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH)-treated B16/F10 murine melanoma cells. Intracellular tyrosinase activity and melanin contents were suppressed by 45% and 74%, respectively, in response to treatment with $100{\mu}g/mL$ of R-EA. Examination of protein expression associated with ${\alpha}$-MSH-induced melanogenesis showed that tyrosinase related protein (TRP)-1 was inhibited more strongly than tyrosinase, and these results were correlated with stronger inhibition of melanin synthesis than intracellular tyrosinase activity. Taken together, R-EA containing p-coumaric acid and resveratrol could be used as a hypopigmentation agent through suppression of sustained extracellular signal-regulated kinase (ERK) activation via melanogenic induction.

  • The Altai Humanities Belt connecting Siberia to Central Asia is very important to the history of civilization. It had a huge influence on the formation of an ancient civilization in the Korean Peninsula. Therefore, a variety of studies have been carried out in the field of folklore and anthropology as well as archeology. One of these studies is about the oral epic. The oral epic remains in the form of a unique transmission in Korea, but it wasn't that long ago when it was noted as the component of the Altai Humanities Belt. In that context, some epics from Central Asia, Mongolia, and Siberia were introduced to Korea. This preliminary investigation is conducted to introduce the oral epic Olonkho from Yakutia in Siberia to Korean academia. Although it was revealed recently, Olonkho is highly valued. The epic study has been buried from the Western point of view, but Olonkho is expected to provide a global perspective to the field of epic study. Above all, it contains a very significant clue to a new study because the content and the style of performance are considerably different from those of the West. Additionally, the original form is relatively well preserved. In particular, it explains how human thinking and behaviors have changed in the transition from the mythical age to the heroic age. This change appears in the ethnic history of Yakutia, as well as in the formation process for all Altai countries around the 10th century. Therefore, this preliminary investigation will be a foundation to facilitate the translation of the voluminous Olonkho into Korean, and to conduct full-fledged research on it. In particular, it can motivate a study on the differences and similarities in comparison to the tradition of oral epics between Central Asia and the Korean Peninsula. Furthermore, it will serve as a foundation for the formation of the Altai Humanities Belt.

  • Background: Incorporation of molecular analysis of the epidermal growth factor receptor (EGFR) gene into routine clinical practice has shown great promise to provide personalized therapy of the non-small cell lung cancer (NSCLC) in the developed world. However, the genetic testing of EGFR mutations has not yet become routine clinical practice in territories remote from the central regions of Russia. Therefore, we aimed to study the frequency of major types of activating mutations of the EGFR gene in NSCLC patients residing in West Siberia. Materials and Methods: We examined EGFR mutations in exons 19 and 21 in 147 NSCLC patients (excluding squamous cell lung carcinomas) by real time polymerase chain reaction. Results: EGFR mutations were detected in 28 of the 147 (19%) patients. There were 19 (13%) cases with mutations in exon 19 and 9 cases (6%) in exon 21. Mutations were more frequently observed in women (42%, p=0.000) than in men (1%). A significantly higher incidence of EGFR mutations was observed in bronchioloalveolar carcinomas (28%, p=0.019) and in adenocarcinomas (21%, p=0.024) than in large cell carcinomas, mixed adenocarcinomas, and NOS (4%). The EGFR mutation rate was much higher in never-smokers than in smokers: 38% vs. 3% (p=0.000). The frequency of EGFR mutations in the Kemerovo and Tomsk regions was 19%. Conclusions: The incorporation of molecular analysis of the EGFR gene into routine clinical practice will allow clinicians to provide personalised therapy, resulting in a significant increase in survival rates and improvement in life quality of advanced NSCLC patients.

  • With the aim to investigation of decay resistance and optimum concentration in chrome-copper-arsenic(CCA) preservative treatment on the imported softwoods from Siberia and North america, preservative absorption after CCA impregnation, weight losses and degradation patterns by decay fungi were examined. The density and latewood rate of Siberia softwoods(Spruce and Larch) were higher than those of North america softwoods(Douglas-fir and Western hemlock), resulting in the decrease of the CCA preservative absorption in the Siberia softwoods. In the case of untreated softwoods, decay resistance against Coriolus versicolor was lower than against Tyromyces palustris. For CCA treated softwoods, preservative effectiveness increased with increase in concentration of CCA solution. When treated with 0.7% CCA solution, efficiency value was more than 80 and 90 for C. versicolor and T. palustris, respectively. From this results, in the CCA preservative treatment for imported softwoods, it can be concluded that optimum concentration of CCA solution is approximately 0.7%. The absorption of CCA preservative distributed in the range of 3.8 and $5.5kg/m^3$. After exposure to testing fungi, in the untreated softwoods, bore holes formed in the cell walls and bordered pits, moreover, bordered pit canals enlarged by the fungi. However, 0.5% CCA treated softwoods was almost no deterioration in the cell walls and bordered pits due to decay.

  • This study is a comparative analysis on the variabilities of spring precipitation and atmospheric circulations of 500hPa surfaces between dry years and wet years over the Korean Peninsula. The distribution of variabilities of precipitation in spring are different from month to month. In March, the pattern is west-high and east-low, in April, north-high and south-low, in May, east-high and west-low respectively. In the distribution of 500hPa geopotential height anomaly, dry years of March show west-high and east-low pattern in that negative anomaly zones are formed around the Korean Peninsula and western coast of the northern Pacific Ocean, and positive anomaly zones are formed in the inland of East Asia centered on Siberia. Consequently, the Korean Peninsula and neighboring regions experience dry season when the zonal flows are strong with the positive anomaly zones of zonal components. On the contrary in the wet years the westerlies are weak since the pattern is east-high and west-low in which the positive anomaly zones are formed over the Korean Peninsula centered on the Aleutian Islands and western coast of the northern Pacific Ocean and the negative anomaly zones are formed in the inland of East Asia centered on Tibet Plateau and Siberia. The dry years of April and May show north-high and south-low patterns in that negative anomaly zones are found from the center of the northern Pacific Ocean to the eastern coast of East Asia, and the positive anomaly zones are found in the center of East Asia extending from Aleutian Islands to Tibet Plateau. On the contrary, in the wet years the patterns show south-high and north-low. This study identified not only that there are contrary atmospheric circulation patterms between dry years and wet years over Korean Peninsua in spring, but also there are different atmosphric circulation patterns between early and late spring.
