Portrait of the writer: the peculiarities of literary technique of Roger Zelazny
Authors: Anisimova Olga Vladimirovna
Published: May 2021

The subject of this research is the unique literary technique of the prominent American fantasy and science fiction writer Roger Zelazny, the author of the world-renowned novels, such as “The Chronicles of Amber”, “This Immortal”, "The Lord of Light”, etc. The article is dedicated namely to determination of the key peculiarities of the poetics of his works. Special attention is given to characterization of his literary path, its periodization, the impact of Zelazny's predecessors – the authors of science fiction and classical world literature – upon his prose. It is noted that R. Zelazny was fascinated with various mythological systems, such as Egyptian, Greek, Norse, Celtic, and Christian. The scientific novelty of this article lies in the attempt to reveal and systematize the most remarkable features of the works of the American fantasy and science fiction writer, whose impact upon the modern fantasy literature can hardly be overestimated; however it has been poorly studied within the Russian literary studies. The conducted analysis of the poetics Roger Zelazny’s iconic novels, created within the framework of the four main stages, indicates the use such postmodernist literary technique as intertextuality. The matter of R. Zelazny is also characterized by psychologism, interpreted as the author's attention to the meticulous reconstruction of the inner cosmos of the hero, which resembles the result of the writer's passion for the ideas of psychoanalysis. Along with the other representatives of the New Wave, Zelazny was prone to the experiment with forms, as well as to the synthesis of the various fantasy genres. Therefore, many of his novels demonstrate the fusion of science fiction, fantasy, space opera, mystery, and detective fiction.

Authors: Starovoitov Ilia
Published: May 2021

This article explores the possible methods of metatext arrangement in the collection of essays “Arabesques” by Andrey Bely in addition to the main the main method described in the works of V. S. Kiselev and M. N. Darwin (the special role of framework components, determined arrangement of texts in contents directory). Special attention is given to the inner composition of texts included in the “Arabesques”, namely their imagery system and framework concepts. The analysis of the essays allowed determining the recurring key antinomies “up/down” and “light/dark”, which reinforce the unified semantic framework of the “Arabesques”. The orientation towards superunity is also detected on the syntactic level due to the constant reference of A. Bely to the “ironic pause” technique. In the modern literary studies, the problem of metatext (particularly in literary and semiotic understanding of the term ) has been brought up by M. N. Darwin, V. S. Kiselev, V. E. Prusenko, A. G. Kulik. However, this article is first to raise the question of their metatextuality the context of Andrei Bely’s collection of essays, which defines the novelty of this research. The author comes to the conclusion that alongside the basic techniques of metatext arrangement, Andrei Bely's “Arabesques” offer a range of additional means for creating semantic superunity – the use of antinomian images common to the collection of essays, and constant reference to the “ironic pause” technique.
On the history of studying proverbs in the Swahili language
Authors: Shatokhina Viсtoriya Sergeevna
Published: May 2021

The subject of this research is the African paremiology. The object is the history of studying proverbs in the Swahili language. The author examines the chronology of studying this field of linguistics by Western European and African scholars, cites their major works, and describes the peculiarities of their scientific views. Special attention is given to the works of the founders of African paremiology, as well as the perspective of modern scholars of Tanzania and Kenya upon the scientific heritage of proverbs and sayings of the Swahili language. The article employs the theoretical research methods, namely the comparison of theoretical works in the Swahili and English languages. The analysis of a wide range of works in the Swahili language alongside the works of certain European authors, allows reconstructing the chronology of the process of studying Swahili paroemias, as well as highlighting most prominent African and European scholars in this field of linguistics. The novelty of this research lies in the fact that this topic is viewed in the domestic African Studies for the first time; foreign linguists also did not pay deliberate attention to this question. The author’s special contribution consists in translation of the previously inaccessible materials of the African and Western European into the Russian language, which helps the linguists-Africanists in their further research.
The transformation of phraseological units as a manifestation of language game in the journalism of V. V. Nabokov
Authors: Knyazeva Natal'ya Vladimirovna , Kurkova Natal'ya Vladimirovna
Published: May 2021

The object of this research is the transformed phraseologisms determined through the method of continuous sampling in the journalistic texts of V. V. Nabokov. The subject of this research is the structural-semantic and functional-pragmatic peculiarities of transforms. The subject of this research is define by various “game” mechanisms of transformations in the area of phraseology, as a result of which the individual-authorial transformations ensure the implementation of the author's plan. The goal of this work is to determine the peculiarities of the authorial transformation of phraseological units in the context of language game, and establish the role of modified phraseologisms in enhancing the influencing potential of the journalistic text. The theoretical and methodological framework contains the works that view the phenomenon of language game and the general principles of occasional transformation of phraseological units. The author advances the hypothesis of the pragmatically justified use of transformed phraseologism, substantiated by the stylistic specificity of resorting to language game as a means of creating certain expressive effect and implementation of the author's plan in the journalistic text. The scientific novelty consists in the complex structural-semantic and functional-pragmatic approach towards studying the transformed phraseological units. This article is first to describe the individual-authorial transformations of phraseological units in the journalism of V. V. Nabokov. It is noted that in the journalistic texts of V. V. Nabokov, the language game pursues both, aesthetic and functional-pragmatic goals, which correlate with the specificity of journalistic genre. The use of familiar, easy to reproduce phraseological units creates a cultural presupposition, which in the context of language game acquires additional connotations, substantiated by game transformation of the usual form and the meaning of phraseological locution, which contributes to the periphrastic expression of the author's attitude towards the topic under review.

Authors: Bedenko Vladimir Nikolaevich
Published: May 2021

Lately, the research of Parody film as a part of film discourse have reached its peak in the history and philosophy of science. The polycode essence of the concept of film discourse prompts changes and modifications in the interpretation of Parody film. Therefore, the subject of this analysis is Parody film. The goal of this research consists in examination of the peculiarities, meaning, and role of the concept of “parody film”, which is a creative work intended to ridicule the plot through satirical or ironic imitation. Research methodology is based on the method of analytical study of sources for clarification of the logic and content of the concepts of “parody”, “parody film”, and “film discourse”, as well for revealing the essence of parody film as a postmodernist deconstruction in cinematography. The article also employs the methods of comparative analysis and the concept of local cultures. The scientific novelty of this research consists in systematization of the existing knowledge on parody film in the light of film discourse, which being the phenomenon at the intersection of multiple disciplines is in the epicenter of scientific inquiries in linguistics, literary studies, sociolinguistics, philosophy of semiotics and film semiotics, critical discourse analysis, and theory of cinematography. The theoretical importance lies in characterization of the concepts of “parody”, “parody film”, “comedy”, “comedy film” in the context of modern knowledge of moviemaking and cinematography. The acquired results give a better perspective on the role of parody film in art and life of the society. The Interpreters fight for cinema, on the one hand adoring it as the art with unlimited capabilities, while on the other – neglecting the fact that it should need the unpretentious demands of the audience. The author claims that in a broad context, the parody film of the XXI century is not aimed at parodying a literary text. The filmmakers rather consider and use parody film as a means for drawing attention of various life circumstances.

Published: May 2021

Pharmacists and pharmaceutical personnel need to support improving the people’s quality of life during the covid-19 outbreak by providing pharmaceutical services, one of which is the Drug Information Service (PIO). Many regions in Indonesia, including DKI Jakarta, have placed large-scale social restrictions since March 2020. In connection with that, the Department of Pharmacy of Atma Jaya Catholic University of Indonesia (PSFUAJ) organized an online PIO program. This program aimed to provide the service of Covid-19 drug-related information and education to the community. The PIO was carried out from April to July 2020 via whatsapp, email, and telephone. In addition, health education was provided through e-flyers, published on Instagram @pio_farmasi_uaj. Eighty percent of the questions were submitted via whatsapp, while the rest was sent via email. Most of the questions submitted (80%) were categorized into self-edication. Further examination shows that the common questions were related to drug choice (27.78%). These data indicate that most questioners tend to provide self-medication first and that they will only see a doctor if they have not recovered or experienced any improvement. PSFUAJ will continue running this program and disseminating this program to a broader audience.

Aim. To assess the features of psychoemotional status in women with climacteric syndrome, manifested by cardiac symptoms.
Materials and methods. The study included 28 women aged 44 to 56 years (M=53,80,7) with menopause-associated complaints, manifested mainly by cardiac symptoms. Modified Kupperman-Uvarova menopausal index was used to diagnose climacteric syndrome and assess its severity. To study the psychoemotional status the Tsung anxiety and depression self-assessment scales were used. Holter ECG monitoring and echocardiography were performed on the ASTEL LTD Cardio DM-3 apparatus for 72 hours.
Results. The most common cardiac complaints in menopausal syndrome were: increased blood pressure, palpitations, recurrent chest pain. Ventricular premature beats were the most common finding. Emotional-affective disorders were found in women of the study group. For women with a mild climacteric syndrome, signs of mood instability, increased emotional lability, irritability, and low levels of anxiety are characteristic. Women with moderate climacteric syndrome complained of anxiety, irritability, anger, and prolonged episodes of decreased mood. According to the anxiety and depression self-assessment scales, these women typically had emotional-affective disorders which manifested by high levels of anxiety, and 29% of them had mild levels of depression. Women with severe climacteric syndrome complained of prolonged episodes of decreased mood, sleep disturbances, and performance impairment; these women predominantly had high levels of anxiety and moderate levels of depressive disorder.
Conclusion. In women with climacteric syndrome, major symptoms are neurovegetative, with a predominance of complaints associated with ventricular rhythm disorders. For climacteric syndrome, affective spectrum disorders are characteristic. The more pronounced the climacteric syndrome, the more severe the anxiety-depressive disorder.

Published: May 2021

Background. Female sexual dysfunction is extremely common and affects about half of the worlds women. Currently, the question of the relationship between gynecological morbidity in women and the characteristics of sexual activity and sexual functioning in a couple remains poorly understood.
Aim. To establish gynecological diseases associated with decreased sexual functioning, sexual health disorders in women on the basis of a screening assessment when visiting the clinic.
Materials and methods. We conducted a cross-sectional descriptive study of the sexual functioning of 1256 women who presented to outpatient appointments. Anamnestic and clinical methods were used, sexological testing using the Female Sexual Function Index questionnaire.
Results. Based on anamnestic data, screening assessment of sexual health and sexual functioning of 1235 women who applied for outpatient appointments to a gynecological clinic, a high gynecological and extragenital morbidity was established in patients (100%). The structure of gynecological diseases is represented by female infertility (48.3%), inflammatory diseases of the genital organs (38.5%; of which salpingo-oophoritis 16.6% and vulvovaginitis 15.9%), endometriosis (13.9%) , menstrual irregularities (8.3%), as well as pain disorders (8.1%). The incidence of infections, predominantly sexually transmitted, was revealed, among them papillomatous viral infection (8.3%), genital herpes (5.3%) and chlamydia (3.7%). It was found that in gynecological patients with diseases characterized by a chronic course, inflammation, pelvic pain, menstrual and reproductive disorders, sexual functioning significantly decreases (p=0.00) and sexual health is impaired. Sexual dysfunctions were detected in 21.6% of patients, their structure is represented by isolated (39.3%) and combined (60.7%) disorders of libido, orgasm, sexual anhedonia, failure of genital response, as well as dyspareunia, vaginismus. In 33.7% of patients, preclinical forms of sexual dysfunction were identified that did not meet the criteria for sexual dysfunction (did not cause distress, were short-lived), but confirmed by the analysis of patient complaints, as well as by the results of the Female Sexual Function Index questionnaire.
Conclusion. Thus, chronic gynecological diseases with inflammatory manifestations, pelvic pain, menstrual and reproductive dysfunctions are associated with decreased sexual functioning, sexual dysfunctions, and preclinical forms of sexual dysfunctions.

More than 600 thousands abortions are performed annually in Russia. Women presenting for abortion care are often motivated by the pregnancy to use effective contraception; they are also at high risk for repeat unintended pregnancy. Contraceptive counseling and the supply of contraceptive methods are part of post-abortion care and positively influence the subsequent use of contraceptive methods. Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. Immediate administration of combined OCs after abortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, and reduce the risk of complications and unintended pregnancies. Сombination of ethinylestradiol 30 g + drospirenone 3 mg demonstrates the advantages of a low estrogen dose with the antimineralocorticoid activity of drospirenone that is responsible for the drugs significant antiandrogenic and antimineralocorticoid effects, reflected clinically in lower rates of adverse events including less fluid retention. Сombination of ethinylestradiol 30 g + drospirenone 3 mg and Metafolin has similar contraceptive efficacy, side effect, safety and benefits profile to other drospirenone-containing contraceptives. The article presents the results of the latest studies about using of combined OCs (ethinylestradiol 30 g + drosperinone 3 mg and Metafolin) after abortion.

The productive power of rising China and national identities in South Korea and Thailand
Authors: Bukh Alexander
Published: May 2021

Drawing on the insights of the constructivist school approach, this
article joins the debate on the effects of rising China in Asia. The
existing scholarship devoted to no-material aspects of China’s rise
focused either on China’s ‘soft power’ initiatives or their reception by
certain audiences. In this article, rising China and its governance
model, are construed as a form of productive power, one that is expected
to bring about not only shifts in material relations and perceptions
but also transformations in the national identities of countries in the
region. This article focuses on South Korea and Thailand, two countries
with fundamentally different political systems but a similar pattern of
recent interactions with China. It analyzes the policymaking elites’
discourse and public attitudes and explores the productive effects of
China’s rise on national identities in the two countries. This article
argues that the impact of China’s rise on elites’ discourse has been
largely negligible with narratives on kinship and historical ties being
used by the elites mostly for instrumental reasons. At the same time,
this article suggests that the recent shifts in public attitudes towards
greater acceptance of authoritarian values observed in South Korea and
Thailand, may be indicative of the productive effect of rising China on
national identities in both countries

Authors: Anggrainy Rani
Published: May 2021

Solar power is considered as the most essential renewable energy in human life, particularly for daily activities. The application of solar water heater is significantly able to reduce the electric load of water heating so that this method is indirectly able to save energy needs. The biggest challenge is increasing the energy density of warm water storage. The best storage medium is paraffin, but it is constrained by the low thermal conductivity of the paraffin and also the wrapping media. This study focuses on efforts to improve thermal conductivity of paraffin as a heat storage medium by using nickel mixture at a ratio (volume) of 10 - 50%. Samples of paraffin and nickel paraffin mixture are inserted into the wrapper of aluminum 6063 material and then tested for heat absorption and release process. The best heat absorption is shown by the sample with the most nickel content, while in the heat release process the best performing sample is shown with a nickel mixture between 20–40%. These results are directly related to the power rate of each sample. The results of this study can be used as a reference for increasing the thermal capacity of warm water storage from solar water heaters.

In the present article, a DFT approach is used at the M06-2X/6-311G((d,p)) level of theory to survey [2+4] Diels—Alder cycloaddition reactions of anthracene with C2X2 (X = H, F, Cl, Me). To illustrate the interaction between two fragments in transition states and products, the energy decomposition analysis is employed. The stability of two feasible products are contrasted. The substituent impact barrier height (ΔE‡) and thermodynamic parameters (ΔG‡ and ΔH‡) of this reaction are found. To check the advancement of the reactions, Wiberg bond indices are applied. Furthermore, the synchronicity values of this reaction are identified.

Published: May 2021

The aim of this research is to optimise the utilization of third runway in Soekarno Hatta International Airport by giving recommendation based on calculation and simulation of runway capacity. The flight schedule data in Soekarno-Hatta International Airport was taken from flightradar24.com for duration of 1- 6 January 2020. The calculation of the runway capacity uses time space analysis method and simulation in BlueSky ATM Simulator. The highest runway capacity of 44 flights per hour is reached when the runway operates as take-off only or landing-only configuration. The simulation is conducted for 3 scenarios: 2 runways configuration, 3 runways configuration and 3 runways configuration with modification. The log data of simulation is analysed using Python programming to know the separation for every pair of flights and ensured that the minima distance due to wake turbulence is fulfilled. The recommendations are runway 07L/25R and 06/24 operates as segregated parallel operation by installing ILS on runway 06/24, extending NP2 and NP3 taxiway for increasing the capacity and reducing the runway incident probability. The results from extending the taxiway are the operation of runway 06/24 will not disturb runway 07L/25R operation, the runway capacity will increase by 60%, and the utilization of third runway will increase by 55%.

Separate lines of research have documented brain atrophy and evidence of autoimmune mechanisms in Gulf War Illness (GWI), including the presence of lupus anticoagulant (LAC), in veterans with GWI. Here we evaluated the possible association of LAC and brain volume in veterans with GWI. The presence of LAC was determined using Silica Clotting Time and dilute Russell’s Viper Venom Time assays. MRI data was acquired using a Philips 3T MR scanner from which total gray matter, total cortical gray matter, total subcortical gray matter, and total cerebral white matter were derived. The results demonstrated a statistically significant reduction of brain volume in all regions tested in GWI veterans with positive LAC, as compared to those without LAC. These findings add to the literature implicating autoimmune mechanisms in GWI and point to the presence of prothrombotic antiphospholipid antibodies as contributing to brain atrophy in GWI.

Given the threat of Vespa mandarinia invasion to ecological balance, according to the data and information provided, the dynamic reproduction model of Vespa mandarinia is established by using natural domain interpolation, and the variation law of total bumblebee with time, latitude, and longitude is obtained. At the same time, we established the classification prediction model by using a neural network and established the mapping relationship between time and space to evaluation grade.We meshed the area provided by the title, assigned values to the location of Vespa mandarinia (VM), and established a VM diffusion model with natural neighborhood interpolation. Its propagation process is simulated by cellular automata. It is determined that VM spreads in a circular shape centered at (122.93174°W, 48.93457°N) and (122.57376°W, 49.07848°N) in the Washington area, with the farthest distance being 1184.4 km and 985 km respectively.We set up a classification prediction model for better classification. According to the image upload time and location, SVM and neural network are used for classification prediction, and the classification accuracy is 74.26% and 97.60%, respectively, and the neural network has higher classification accuracy. So we choose the neural network.

Published: May 2021

The experiences of coping with adversities among nine Latinx adult participants (six females, three males) who self-identified as ethnically mixed were explored through semi-structured, individual interviews. Participants identified a range of challenges related to their mixed identity status, including experiences of discrimination and instances of identity conflict. Participants specified methods of overcoming challenges they faced as mixed individuals including seeking cultural commonalities, finding strength and pride within their cultures, exercising acceptance, and emphasizing aspects of oneself depending on contexts and circumstances. Finally, participants discussed resilience related growth experiences related to their mixed identity characterized by improved relationships and self-esteem. The findings provide detailed information about resilience for these mixed Latinx individuals that may be helpful in better understanding and serving others who identify similarly.
