Trans-Siberian Railway (TSR) has been recently rising to the surface as the world important issue with Trans-Korea Railway (TKR). This can change transportation means from sea to railway and enhance Korean international position through the North-east Asian economic cooperaton with Russia. In particular, when 'Iron Silkroad' linking TKR is created, it can revitalize the underdeveloped East Russia and Far East's economies and Korean railway can play a key role as the North-east Asian logistics center and exerts a powerful influence on them. In addition, Korean railway expects to obtain economic benefits accruing to various value-added businesses such as IT, tourism, especially, transportation business from the East Siberia, the world largest reserves of energy to Korea. This study tries to find economic value analysis and guidelines on strategies of Korean railway with international logistics base built in Khassan (Vladivostok contiguity region) through the development of energy deposited around east of TSR.

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.

Research on Korean nematocerous flies (Diptera: Nematocera) was started by the National Institute of Biological Resources in 2012. This publication is a continuation of our previous work. During the season of 2019 insects were collected in Odaesan National Park by the researchers from Korea University. Among these samples, two specimens belonging to the family Hesperinidae, which was previously unrecorded from Korea, were noticed. This family is known from countries bordering Korea (East Siberia and Far East of Russia, Hokkaido Island of Japan), thus occurrence of hesperinid flies was expected on the Korean Peninsula. Only one genus Hesperinus Walker, 1848 with eight species belong to this family. They are developing in decaying wood of deciduous trees. Hesperinus rohdendorfi Krivosheina & Mamaev, 1967, which was known from East Siberia and Far East of Russia is recorded from South Korea. Redescription and photographs of the most important taxonomical details are presented.

Background: There is a large amount of evidence that the ABO blood group system may play a role in disease etiology. A relationship between ABO and Rhesus blood groups and cancer risk has been demonstrated in a number of studies. However, in relation to gynecological malignancies, these findings are inconsistent and contradictory. Aim: To perform a case-control study for analysis of the distribution of ABO and Rh blood antigens among women from South-East Siberia who suffered from ovarian, endometrial and cervical cancer, and to assess the potential role of these antigens in carcinogenesis. Design, Subjects and Methods: A total of 1,163 cases with ovarian cancer (n=551), endometrial cancer (n=440) and cervical cancer (n=172) were involved in the study. The control group was formed from 22,581 female blood donors. Blood groups were determined through patients medical records and blood donor records. Odds ratios (OR) with 95% confidence intervals (CI) were calculated. The blood group O was defined as the referent group, as it has the greatest frequency in the populations of Southern Siberia. P values less than 0.05 were regarded as statistically significant. Results: We found that carriage of non-O blood types increased the risk of ovarian cancer by 40-60%, and the magnitude of this relationship was strongest in women with the AB (IV) blood group. Carriage of the A (II) blood group strongly correlated with an increased risk of ovarian cancer in premenopausal, but not in postmenopausal women. No statistically significant correlations were obtained for endometrial cancer and cervical cancer. Additionally, we did not observe a relationship between Rhesus factor and cancer risk. Conclusion: We suggest that carriage of non-O blood groups may elevate risk of ovarian cancer and can play a role in its development.

Colorectal cancer remains one of the most widespread malignancies in the world. However, there is a lack of comprehensive studies considering colorectal cancer risk factors among Russian populations, particularly in Siberia. The aim of this investigation was to determine the impact of various lifestyle, dietary, family, and socioeconomical factors on colorectal cancer risk in South-East Siberia. We recruited 185 Russian colorectal cancer cases and 210 gender-, age-, and ethnicity-matched asymptomatic controls with no history of any malignant tumor, using a specially designed questionnaire to obtain relevant information. After the statistical analysis, we defined several significant factors affecting colorectal cancer risk. Among these were smoking (OR=2.13, 95%CI=1.4-3.24, P=0.0004), being overweight (BMI between 25-30, OR=2.45, 95%CI=1.49-4.03, P=0.0004), alcohol drinking (OR=8.73, 95%CI=5.49-13.87, P<0.0001), beer drinking (OR=9.24, 95%CI=5.14-16.61, P<0.0001), consumption of hard liquor (OR=9.37, 95%CI=5.92-14.82, P<0.0001), excessive red meat consumption (P<0.0001), excessive intake of red meat products (P<0.0001), excessive intake of dairy products (P<0.0001), excessive sour cream and cheese consumption (P<0.0001 and 0.0002, respectively), spicy food consumption (OR=2.87, 95%CI=1.9-4.33, P<0.0001), family history of gastrointestinal malignant tumors (OR=3.99, 95%CI=2.09-7.59, P<0.0001), and income exceeding twice the subsistence minimum (OR=5.34, 95%CI=3.35-8.53, P<0.0001). Certain factors, such as high concentration of salt in the food and precancerous colonic lesions, demonstrated borderline significance (OR=3.45, 95%CI=1.68-7.1, P=0.0008, and OR=5.25, 95%CI=1.94-14.22, P=0.001, respectively). Some factors were established as protective, like consumption of rye bread and both rye and wheat bread (OR=0.32, 95%CI=0.21-0.5, P<0,0001, and OR=0.07, 95%CI=0.02-0.21, P<0.0001, respectively), and also low concentration of salt in the food, although this was of borderline significance (OR=0.43, 95%CI=0.26-0.69, P=0.0006). ABO and Rhesus blood antigens were not associated with increased colorectal cancer risk. These results should be definitely applied for elaboration of programs of colorectal cancer prevention in Russia, particularly in Siberia.

Monthly mean chlorophyll concentration in the East Sea was estimated from the ocean color observed by the Coastal Zone Color Scanner (CZCS) on Nimbus-7 satellite which had performed various remote sensing missions from 1979 to 1986. The areas of high chlorophyll concentration were found in the sea between Siberia coast and Sakhalin Island, in the Donghan Bay and in the Ulleung Basin. In the southwestern East Sea, especially in the area near Ulleung Island, the yearly maximum chlorophyll concentration occurred in December. The chlorophyll concentration in Ulleung Basin in December was about two times higher than during spring bloom in April. The early winter bloom occurred in the warm side of the front that was formed between warm water from the East China Sea and nutrition rich cold water from the northern East Sea.

Global climate warming induced by long-lived greenhouse gases is expected to cause increases in wildfire frequencies and intensity in boreal forest regions of mid- and high-latitudes in the future. Siberian forest fires are one of important sources for air pollutants such as ozone and aerosols over East Asia. Thus an accurate quantification of forest fire influences on air quality is crucial, in particular considering its higher occurrences expected under the future warming climate conditions. We here use the 3-D global chemical transport model (GEOS-Chem) with the satellite constrained fire emissions to quantify Siberian fire effects on ozone concentrations in East Asia. Our focus is mainly on spring 2003 when the largest fires occurred over Siberia in the past decade. We first evaluated the model by comparing to the EANET observations. The model reproduced observed ozone concentrations in spring 2003 with the high $R^2$ of 0.77 but slightly underestimated by 20%. Enhancements in seasonal mean ozone concentrations were estimated from the difference in simulations with and without Siberian fires and amounted up to 24 ppbv over Siberia. Effects of Siberian fires also resulted in 3-10 ppbv incresases in Korea and Japan. These increases account for about 5-15% of the ozone air quality standard of 60 ppbv in Korea, indicating a significant effect of Siberian fires on ozone concentrations. We found however that possible changes in regional meteorology due to Siberian fires may also affect air quality. Further study on the interaction between regional air quality and meteorology is necessary in the future.

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.

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.

The sudden stratospheric warming (SSW), which is characterized by an abrupt increase of polar stratospheric temperature by several tens of degrees in a week, has been known to affect tropospheric weather and climate on sub-seasonal time scale in the boreal winter. Such downward coupling has been often examined in North Atlantic and Europe, but rarely examined in East Asia. In this study, by applying the two definitions of SSW to the reanalysis data, the possible impacts of the SSW events on the surface air temperature (SAT) and tropospheric circulation in East Asia are analyzed. It is found that Eurasian continent, including Siberia and the Northeast Asia, tends to experience anomalously cold SAT for up to sixty days after the SSW events. The resulting SAT anomalies largely resemble those associated with negative Artic Oscillation. However, over East Asia, SSW-related SAT change is weak and not statistically significant. Only during the extreme SSW events when the downward coupling between the stratosphere and troposphere is strong, East Asia exhibits significantly cold SAT anomalies. This relationship is presented by grouping SSW events into those followed by cold SAT anomalies over East Asia and those by warm anomalies for varying threshold values of the SSW events.
