Future of Railways - in Open Systems?
Dmitry A. Macheret 한국철도학회 2012 International Journal of Railway Vol.5 No.4
The article suggests criteria of dividing transport systems into systems of limited and open access. Possibilities of implementing principles of the open access in conjunction with the adaptive control at the railway transport have been analyzed. The author makes a grounded conclusion that the development of transport systems based on the open access and adaptive control can play a positive role in overcoming the global instability of the economy and form prerequisites of its stable grows.
A minimally invasive first stage of ALPPS for hepatoblastoma in a child
Dmitry Akhaladze,Natalia Uskova,Gavriil Rabaev,Denis Kachanov,Nikolay Grachev 한국간담췌외과학회 2020 Annals of hepato-biliary-pancreatic surgery Vol.24 No.3
Large and giant tumors, especially hepatoblastomas, are more frequently presented in pediatric patients. At about two-third of hepatoblastomas at the time of diagnosis are unresectable and liver transplantation is considered as a treatment of choice because of insufficient future liver remnant volume. In selected cases, 2-staged hepatectomy may be the unique chance for curative resection except hepatectomy followed by liver replacement. Despite the overwhelming spread of minimally invasive liver surgery, the laparoscopic approach remains uncommon in children. A case of successful partial associating liver partition with portal vein ligation for staged hepatectomy firstly accomplished pure laparoscopically on the first stage in an infant is presented. Described experience suggests both: the feasibility of laparoscopic procedures and the effectiveness of partial in situ liver splitting to reach appropriate future liver remnant volume and to avoid liver transplantation and its disadvantages.
Role of Rail Transport in Business Activities
Dmitry A. Macheret 한국도시철도학회 2013 IJAR Vol.1 No.1
The article shows the role of the railway transport in the implementation of business activities. Classification of variants of the railway transport usage as a tool for the implementation of revenue opportunities is proposed. For each option a methodology for the transport costs assessment is developed. The essence of the entrepreneurial aspect of the railway transport in the sphere of cargo transportation is described. Conclusion about the need of flexible railway tariff change in reaction to market changes is made.

The fate of Nikolai Marr’s linguistic theories: The case of linguistics in the political context
Dmitry Shlapentokh 한양대학교 아태지역연구센터 2011 Journal of Eurasian Studies Vol.2 No.1
Those who study the development of linguistic theories and related intellectual trends do not usually like to see intellectual trends as being directly shaped by societal changes or, even more so, by the direct intervention of raw power. As a matter of fact, it is believed that it is ideology that shapes the political and social reality. The belief in the absolute power of “discourse” over pliable social/political matter (in this interpretation, discourse permeates and shapes the social/political reality in a sort of neo-Platonic way) is shared not just by the aging post-modernist left, but even by the right—indeed, by quite a few “neocons,” who believe that ideology is of the foremost importance. According to the USA neocon strategists, it requires little eloquence to convince people that the American capitalist democracy is the best among the possible options. The military, of course, should also provide essential help by removing tyrants who prevent people from being fully cognizant of their inalienable rights. Thus, the war against “Islamofascism” is to be primarily fought on the “fields of discourse.” Still, a detailed analysis of the ideological trends could easily reveal that not only has ideological construction emerged from the political realities but also that raw power—especially in totalitarian states—shapes the course even of the majority of theoretical discussions, such as those that deal with linguistic or historical phenomena of the distant past. The case of Nikolai Marr, the leading Soviet linguist in the early Soviet era, and the legacy of his theories could be a good example.
Moscow as international financial center: Ideas, plans and perspectives
Dmitry Abramov,Stanislav Polezhaev,Mikhail Sherstnev 한양대학교 아태지역연구센터 2011 Journal of Eurasian Studies Vol.2 No.2
The paper provides an overview of the Russian official plans of development of the international financial center (based primarily in Moscow) and tries to stimulate the discussion on the critical assessment of the perspectives in order to outline the efficient ways to achieve this ambitious goal.
Byzantine history and the discourse of the Russian political/intellectual underground
Dmitry Shlapentokh 한양대학교 아태지역연구센터 2012 Journal of Eurasian Studies Vol.3 No.1
Historical subjects often seem to be unrelated to current political discourse still could be often politicized in present-day Russia. And Internet discussions on these historical subjects could well provide insight into the views of the various segments of the country's population. These Internet discussions become especially important sources when one tries to look into the minds of the Russian underground, those who have practically no legal outlet for presenting their views. For this reason, the movie The Death of the Byzantine Empire, shown in the very end of the Putin presidency, is especially important. The movie, created the Orthodox priest Tikhon Shevkunov, (presumably Putin's confessor) made clear references to contemporary Russia. In the view of the producer, the Byzantine Empire was strong when it followed its autocratic tradition and was attached to Orthodoxy. The movie generated extensive discussions, including among those who belong to Russia's political and intellectual fringe. Quite a few of them were neo-pagans; for them, Christianity, including Orthodox Christianity, was Russia's curse. For them, it was an Asian creed foreign to Aryan Russians. The fact that it was accepted by Russians implied that Russians had been subjugated by an alien, Asiatic, force. Many of these neo-pagans were quite pessimistic in regard to the country's future; and, indeed, their response indicates the deep alienation of quite a few Russians, which hardly bodes well for the country's future.

Holothurian triterpene glycosides are known to possess multiple biological activities. Here we show that cucumarioside A_2-2 from the Far-Eastern edible holothurian Cucumaria japonica possesses potent immunomodulatory properties. The present studies were done to determine if cucumarioside A_2-2 would affect macrophage adhesion, spreading, and motility. Resident peritoneal macrophages, collected from BALB/c mice, were exposed in vitro to low concentrations of cucumarioside A_2-2 and compared with appropriate controls. Results indicate that 0.02 μg/mL cucumarioside A_2-2 significantly enhanced macrophage morphology parameters and behavior. The glycoside stimulated these parameters by increasing the number of cells with increased adhesion properties as well as the spreading reaction and motility velocity by at least almost twofold. The data are discussed in terms of possible mechanisms underlying the immunomodulatory properties of cucumarioside A_2-2.
