  • 동시베리아 지역에 분포하는 영구 동토층의 두께는 평균적으로 200~500m이며, 기온에 따라 지반물성이 변화하는 계절동토층이 지역에 따라 지표면에서 약 0~4m까지 형성되어 있다. 계절 동토의 전단파 속도는 흙의 종류에 따라 여름에는 약 80m/s에서 겨울철 동결상태에서는 약 1500m/s까지 크게 변이한다. 융해시 계절 동토층과 하부의 영구 동토층 사이의 전단파 속도 차이 때문에 매우 큰 임피던스가 발생하고 이로 인해 지진파가 증폭될 수 있다. 특히, 경계면에서 큰 변위가 발생할 수 있으므로 내진설계 시 이의 영향을 고려해야 한다. 본 연구에서는 계절 동토층의 두께와 전단파 속도 변화에 따른 영향이 지반 증폭특성 및 지반변형에 미치는 영향을 규명하기 위하여 1차원 등가정적 지반응답해석을 수행하였다. 동시베리아의 Yakutsk와 Chara 지역에 대한 지질보고서를 바탕으로 지반주상도를 선정하였으며 입력지진파의 영향을 증명하기 위해 총 20개의 계측지진파를 사용하였다. 계절 동토층의 두께가 증가할수록 증폭현상이 크게 발생하였으며, 계절동토층과 영구 동토층 사이의 전단파 속도 차이가 클수록 증폭계수가 증가하는 것으로 나타났다. 특히 동시베리아 지역에 넓게 분포되어 있는 유기질토인 토탄은 증폭에 큰 영향을 미치므로 설계시 이를 반드시 고려해야 할 것으로 판단된다.

  • 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.

  • 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.

  • 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.

  • 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.

  • An efficient system for in vitro bulblet formation of Lilium oriental hybrids(cvs). Casa Blanca and Siberia is described. Transverse thin cell layer(tTCL)(1mm thick) explants of 'Casa Blanca' formed bulblets at a frequency of 97.7% when cultured on Murashige and Skoog (MS) medium supplemented with 1mg/L 2,4 dichlorophenoxyacetic acid(2,4-D) (On average 15.6 bulblets were formed per explant). The frequency of bulblet formation was drastically reduced when the explant ghickness was thinner than 1 mm. Explants from the outermost layer of bulb scale produced greater frequency of bulblet formation than middle or innermost layer. Among auxins supplemented to culture medium at 1 mg/L, 2,4-D led to greater frequency of bulblet formation on explants than dicamba, picamba, or phenylacetic acid(PAA). tTCL explants from the middle region of the outermost layer bulb scale yielded greater frequency of bulblet formation than the upper or lower region. tTCL stem explants of 'Siberia' formed bulblets at a frequency of 95.3% when cultured on MS medium with 1 mg/L 2,4-D(On average 9.1 bulblets were formed per explant). The system estabilished in this study will be useful for in vitro rapid propagation and genetic transformation of Lilium Oriental hybrids.

  • Kemerovo is an industrial region of the Russian Federation characterized by highly developed mining, chemical, metallurgical and power industries. Many of the factories were closed down due to the socioeconomical crisis in the early 90's, and economic potential of the survivors has also decreased significantly. Paradoxically, this has led to the improvement of the ecological situation in the region and elimination of exposure to many chemical carcinogens. This factor, in combination with the improvement of oncological care, might be expected to have lead to a decline of cancer incidence and mortality in the region. To assess trends of cancer incidence and mortality in Kemerovo Region, we therefore carried out an analysis of relevant epidemiological data during 1991-2010. In fact, a significant increase of cancer incidence overall was revealed during 2001-2010. Male cancer incidence was significantly higher than female cancer incidence. Regarding gastric cancer incidence, statistically significant differences during 2001-2010 were found only for men, and male incidence exceeded female incidence. Concerning colorectal cancer incidence, it was lower during 2001-2005 and 2006-2010 as compared to the period of 1991-1996. Lung cancer incidence was significantly higher during 1991-2000 compared to 2001-2010. Among urban populations, cancer incidence was higher in comparison with rural population, but a gradual steady convergence of trends of cancer incidence among urban and rural populations was noted. Lung cancer, breast cancer, colorectal cancer, non-melanoma skin cancer, and gastric cancer are the most prevalent cancer forms in Kemerovo Region. There were no differences in cancer mortality between 2001-2005 and 2006-2010; however, male cancer mortality exceeded female cancer mortality. A similar situation was observed for gastric cancer, colorectal cancer, and lung cancer. Cancer mortality among urban populations exceeded mortality among rural population, for both genders. We suggest that these data can be used for development of modern programs of cancer prevention and early diagnostics in industrial regions of 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.

  • 화훼 수출 검역에서 기존 메틸브로마이드 훈증보다 경제적이고 친환경적이며 안전한 대안으로서 감마선 융복합 처리 기술을 백합 잎마름병 방제에 적용하였다. 감마선 융복합 처리는 200 Gy 감마선과 이염화이소시안산나트륨(NaDCC) 은나노 입자(NSS)의 화학대체제를 시베리아, 르네부, 소르본느 품종의 절화 백합이 담긴 수출포장용 종이상자에 총 6회로 실시하였다. 감마선 조사 8일 후 백합 잎과 꽃잎에서 측정한 발병율(disease incidence)과 발병도(disease severity)로 분석 결과, 감마선은 소르본느 잎에서 발병도를 약 13-25% 감소시킨 반면, 르네부 잎에서는 발병도를 2-5% 증가시켰다. 화학대체제 처리와 무처리를 비교한 결과 절화 백합 수출현장에서 화학대체제의 잎마름병 발병 억제 효과를 기대할 수 없었다. 한편, 조사 12일 후 감마선 처리 유무에 따른 백합 잎의 엽록소 함량 비교 결과 감마선에 의해 통계적으로 유의하게 감소하였고, 시베리아와 소르본느 꽃의 만개 기간을 0.4-1.2일 연장시켰다. 또한 감마선이 조사된 절화는 화병에서 무처리에 비해 마름이 발생하여 생중량 감소가 뚜렷하였다. 한편, 1과 2 kGy 고선량 감마선은 백합 꽃봉오리 끝 부분을 짙은 갈색으로 변색시키거나 꽃봉오리 목 부분의 꺽임, 봉오리가 개화하지 못하게 하는 등 마름 이외에도 감마선 과도에 의한 품질저해 피해가 나타났다.
