Этнонимия ороков Сахалина в трудах исследователей (вторая половина XIX – начало XXI вв.)
Anatoly Fedorovich Startsev 충북대학교 러시아 • 알타이지역 연구소 2023 러시아학 Vol.- No.26
Many Russian and researchers from Japan, Finland, Poland and other states dealt with the problems of ethnonymy and ethnic history of Sakhalin’s oroks. More than twenty ethnic names are noted in their works: Orochon, Olcha, Ulcha, Ulta, Uilta and others. Russian researchers of oroks believe that the etymology of these names is reflected in the words of the oron and ula, meaning “home deer”, and the ethnic names of the oroks are translated In Russian as "reindeer herders". In addition, modern Russian ethnographers, not taking into account the theory of the ethnic group, explaining that each nation, in addition to the main name of the endoethnonym, may have several more territorial names characteristic of different ethnographic groups. However, post -Soviet researchers began to equate the numerous orki names with one word. In the studies of the post -Soviet period, the ethnonyms of Ulta ~ Uilta ~ Ujlta began to unite Tilda, while the name of the Ujlta, as the original ethnonym of Sakhalin’s orcs, was preferred. The author of this article adheres to a concept, according to which the numerous names of the oroks of Sakhalin in the form of Ulta, Uilta, Ujlta cannot be reduced to one name, since these are different names of ethnographic groups indicating the territory that previouslythe ancestors of the oroks lived. The article critically comprehends the position of researchers who continue to use the term Ujlta instead of the true name of Uilta. Obviously, the current problem of using the ethnonyms of Sakhalin’s oroks can get its final solution only in the works of the new generation of Russian researchers.
BROYDEN’S METHOD FOR OPERATORS WITH REGULARLY CONTINUOUS DIVIDED DIFFERENCES
Anatoly M. Galperin 대한수학회 2015 대한수학회지 Vol.52 No.1
We present a new convergence analysis of popular Broyden’s method in the Banach/Hilbert space setting which is applicable to non- smooth operators. Moreover, we do not assume a priori solvability of the equation under consideration. Nevertheless, without these simplifying as- sumptions our convergence theorem implies existence of a solution and superlinear convergence of Broyden’s iterations. To demonstrate practi- cal merits of Broyden’s method, we use it for numerical solution of three nontrivial infinite-dimensional problems.

Objective: The objective of this study was to assess serum, hair, and urinary magnesium (Mg) levels in children with attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and both ASD and ADHD to reveal potential interactive effects. Methods: A total of 148 boys aged 4–9 years old were enrolled in this study, including 44 children with ADHD, 40 pediatric patients with ASD, 32 patients with both ADHD and ASD, as well as 32 healthy neurotypical children. Hair, serum, and urinary Mg levels were assessed using inductively-coupled plasma mass spectrometry (ICP-MS). Laboratory quality control was performed using certified reference materials of human hair, plasma, and urine. Results: No significant group difference in serum Mg levels was observed. Mg content in hair was found to be reduced in children with ADHD and ADHD+ASD compared to that in healthy controls by 11% and 15%, respectively. Urinary Mg levels in children with ADHD+ASD exceeded the control, ADHD, and ASD values by 51, 76, and 65%, respectively. Factorial analysis revealed significant contribution of ADHD to hair and urinary Mg levels. Multiple regression analysis demonstrated that hair and urinary Mg levels were considered as significant predictors of neurodevelopmental disorder complexity. Conclusion: We propose that impaired Mg status may provide a link between ADHD and ASD.
Solution in Closed Form of Boundary Value Problem for Degenerate Equation of Hyperbolic Typ
Anatoly A. Kilbas ...et al KYUNGPOOK UNIVERSITY 1996 Kyungpook mathematical journal Vol.36 No.2
The paper deals with a boundary value problem for a partial differential equation ofhyperbolic type with boundary conditions involving generalized fractional integrals andderivatives with the Gauss hypergeometric function in the kernel. By using the propertiesof the fractional calculus operators in Hölder spaces it is shown that this problem canbe reduced to a singular integral equation with the Cauchy kernel, and its solvabilityconditions and a solution in a closed form are given.
