© 2017, Slovenska Vzdelavacia Obstaravacia. All rights reserved.This paper deals with the training of engineers, the role of the humanities in the course of vocational training in higher school. The authors conclude that a modern world of information requires a fairly high level of language training and the development of humanitarian thought, which is intended to arm a specialist not only with a certain amount of knowledge, but also to shape the qualities of educated person, a competent engineer. The authors in this paper examine the issue of professional competence, emphasizing fundamental importance of the teacher, who lays the foundations for this process. This paper gives a fairly clear idea of educational process management, ways of presenting new educational information. The paper reveals the role of the engineer in society, strategic objectives of humanitarian education are indicated concisely and clearly, as well as the attitudes and relations which it aims to build and develop for younger generation

Pairing of applicants’ CJM with university profile in digital environment as a management task

The work is devoted to the application of the Customer Journey Map (CJM) for university applicants and managerial tasks of adapting the profile of the university in the digital environment to the trajectories of the consumer. The author’s definition of the “profile of the university in the digital environment” concept is offered, the analysis of statistical data of university websites is made. The combination of classical studies of applicants’ motivation and factors influencing enrollment in a particular university with modern methods of studying consumer behavior in the digital environment allows to increase the effectiveness of the admission campaign. Customer Journey Map as an analysis tool, in conjunction with the data of network traffic allows to optimize all types of communications of the university and provide its management with necessary information when making managerial decisions. The research revealed an insignificant influence of the university social networks and thematic groups on the decision to enroll to a particular university, which what caused a deeper study of visitors’ behavior on the university websites. Internet traffic activity for a number of universities was assessed as direct requests, through search services, social networks, mail servers, as well as through referral links, and advertising traffic. The study showed that search engines and direct queries gave the maximum value for traffic. But the effectiveness of advertising to attract applicants is rather low, which indicates the insignificant role of university advertising and confirms the data of the survey in the construction of the Customer Journey Map

FG Sge: new multicolor photometry and short-term dust shell clearing in 2019

We present the results of a new stage of the long-term photometric study of FG Sge which is a quickly evolving central star of the planetary nebula Hen 1-5. Our new observations carried out on the SAI MSU telescopes in the optical ($BVR_CI_C$) and infrared (IR) ($JHKLM$) regions in 2008-2021 and 2013-2021, respectively, allowed us to trace the evolution of the star's brightness in recent years. The most significant observations were performed in 2019 when the star suffered a short clearing of the dust shell and became visible in $BVR_C$. Based on the spectral energy distribution of FG Sge in the 0.4-5 $\mu$m wavelength range we derived the dust shell parameters: the size of dust grains $a=0.01\mu$m, the inner radius temperature $T_{\text{dust}}=900$ K, optical depth $\tau (K)=0.5$ ($\tau (V)=4.5$), the total mass of dust $M_{\text{dust}}=7\cdot10^{-5} M_{\odot}$. After the short-term clearing of the dust shell in 2019, another dust structure was ejected that resulted in the star fading in all the observed bands. Based on the IR brightness and color curves, we estimated the dust depth growth in 2019-2020.Comment: 17 pages, 9 figures, 3 tables. Accepted for publication in Astronomy Letter

Modeling the spectrum of V4334 Sgr (Sakurai's Object)

Theoretical spectral energy distributions were computed for a grid of hydrogen-deficient and carbon-rich model atmospheres of T(eff) in the range of 5000-6250 K and log g = 1.0 - 0.0 by the technique of opacity sampling, taking into account continuous, molecular band and atomic line absorption. These energy distributions were compared with the spectrum of V4334 Sgr (Sakurai's object) of April, 1997 in the wavelength interval 300-1000 nm. We show that (1) the shape of the theoretical spectra depends strongly on T(eff) but only very weakly on the hydrogen abundance; (2) the comparison of the observed and computed spectra permits to estimate T(eff) approximately 5500 K for V4334 Sgr in April, 1997, and its interstellar reddening (plus a possible circumstellar contribution) E(B-V) approximately 0.70.Comment: 7 pages, 8 figures, LaTeX, accepted by Astronomy and Astrophysic

Observation of nonlinearity-controlled switching of topological edge states

We report the experimental observation of the periodic switching of topological edge states between two dimerized fs-laser written waveguide arrays. Switching occurs due to the overlap of the modal fields of the edge states from topological forbidden gap, when they are simultaneously present in two arrays brought into close proximity. We found that the phenomenon occurs for both strongly and weakly localized edge states and that switching rate increases with decreasing spacing between the topological arrays. When topological arrays are brought in contact with nontopological ones, switching in topological gap does not occur, while one observes either the formation of nearly stationary topological interface mode or strongly asymmetric diffraction into the nontopological array depending on the position of the initial excitation. Switching between topological arrays can be controlled and even completely arrested by increasing the peak power of the input signal, as we observed with different array spacings.Comment: 8 pages, 6 figure

Immunoglobulins and predicted mortality in clinical course of concomitant HIV and TB infection

A search for prognostic markers of HIV and tuberculosis coinfection (HIV/TB), especially in case of Mycobacterium tuberculosis multidrug resistance (MDR MBT) associated with low rates of TB eradication, is of relevance in connection with the problem of choosing adequate anti-TB therapy which is able to decrease mortality. 113 HIV/TB patients aged 24 to 58 years were examined: 70 males and 43 females hospitalized at the Novokuznetsk TB Clinic during the 2017—2019 period. MDR MBT (concomitant resistance to Isoniazid and Rifampicin) was found in 50 patients (12 patients with MDR MBT had additional resistance to Fluoroquinolones) aged 24 to 54 years — 31 males and 19 females. The control group consisted of 49 healthy individuals aged 27 to 72 years (26 females and 23 males) lacking focal and systemic infections with moderately pronounced age-related changes. In plasma samples, concentration of total (non-specific) immunoglobulins of classes E, M, G, A (including secretory immunoglobulin A, sIgA) were measured by using enzyme-linked immunosorbent assay. Data statistical processing was performed by using licensed software packages InStatII, Microsoft Excel, IBM SPSS Statistics 22. An extended range of individual variability in count of peripheral blood CD4 lymphocytes was revealed both among non-survivor and survivor patients with HIV/TB examined, being a drawback of using such parameter as lethality predictor. It was found that the serum level of total IgE, IgM, IgG, IgA and sIgA in patients with HIV/ TB was higher than that one in control group, whereas in non-survivor vs. survivor patients the concentration of IgE and sIgA was elevated. The coefficient of disease outcome prediction (CP) for patients with HIV/TB and MDR MBT was calculated being equal to the ratio of the multiplication of serum concentration of IgE, IgM, IgA and secretory IgA to CD4 lymphocyte count (CP = IgE x IgM x IgA x sIgA/CD4). CP higher than 200 was detected in 77% non-survivor and 6% of survivor patients. The relative risk of death with CP > 200 was very high (OR = 56.7, p < 0.0001) being 8.5 times higher than that one upon CD4 < 200 (OR = 6.7, p = 0.0237). A positive correlation between CP and lethal outcome was more valuable than that of CD4. The data presented allow us to propose CP for clinical use as an effective prognostic criterion for HIV/TB with MDR MBT

INTERRELATION OF STEROID RECEPTOR GENE EXPRESSION IN UTERINE TISSUES AND SERUM CONCENTRATIONS OF IMMUNOREGULATORY PROTEINS, CYTOKINES, SEX STEROIDS IN PROLIFERATIVE DISEASES

Pathogenetic mechanisms of uterine leiomyoma, adenomyosis and their combination are complicated and poorly understood, a differential diagnosis of leiomyosarcoma of the uterus is difficult. Our study aimed for a comparative analysis of the serum contents of α2-MG, PAG, some cytokines, sex steroids and the expression of steroid receptor genes in the patients with different variants of uterine proliferative diseases, in order to determine their pathological role, diagnostic and prognostic value. Expression of estrogen receptor genes adenomyosis nodes was 1.5 to 2-fold higher than in leiomyoma, the combined pathology showed intermediate values, and expression of ER and PGR genes in leiomyosarcoma was minimal. In cellular leiomyoma, expression of ER receptor genes in the surrounding myometrium was 2 to 3-fold higher than in cases of simple leiomyomas. At the same time, concentration of estrogen and progesterone in the blood is comparable between the groups and control groups. All the patients have a deficiency of immunomodulatory α2-MG (12-13% for leiomyomas, 20% for adenomyosis, and 23% for malignant pathology). The concentration of immunosuppressive PAG is increased in combined conditions and leiomyosarcoma. In addition, the contents of IL-6 and TNFα increase, the VEGF levels exceed normal values 4 to 4.5-fold, in leiomyoma, 5.5-fold, in combined pathology, 6.5, in adenomyosis, and 10-fold, in leiomyosarcoma.The obtained results confirm that immunomodulatory proteins, cytokines and cell-targeting sex hormones exert an interdependent influence upon each other in the studied diseases, and their significant changes may be used in diagnostics and prognosis
