Authors: Hania Wa Ode Saqya , Afiatin Tina
Published: May 2021

Relasi perkawinan merupakan hubungan interdependensi antara suami dan istri. Ketika suami melakukan tindak pidana korupsi, maka dapat menimbulkan rasa malu bagi pasangannya. Penelitian ini bertujuan untuk memahami dinamika psikologis rasa malu pasangan (istri) koruptor serta faktor-faktor yang terlibat di dalamnya. Partisipan penelitian adalah seorang istri yang menggugat cerai suaminya akibat kasus korupsi yang dilakukan suaminya. Metode kualitatif studi kasus digunakan dalam penelitian ini. Pengambilan data dilakukan dengan wawancara mendalam dan studi dokumentasi. Hasil penelitian menunjukkan bahwa rasa malu yang dialami partisipan ter manifestasikan dalam perasaan-perasaan marah, kecewa, sedih, sakit, kesepian, kehilangan, takut terekspos, defect, dan tidak bahagia. Rasa malu yang dialami muncul dari adanya identitas bersama yang mengancam citra diri partisipan. Koping yang dilakukan partisipan untuk keluar dari rasa malu adalah dengan melupakan, memutus berbagi identitas dengan bercerai, dan memperbaiki citra diri. Dinamika rasa malu pasangan (istri) koruptor melibatkan tiga faktor yang berpengaruh besar, yakni karakteristik partisipan, keinginan partisipan agar anaknya memiliki kebanggaan atas orang tuanya, dan relasi dengan keluarga.

Published: May 2021

The Covid-19 pandemic has changed the life order of entire community including employees from dual-earner families. Overlapping roles experienced can cause tension and trigger work-family conflicts that can impact workplace well-being. Previous studies had often focused on well-being in general and there was a lack of research related to well-being in dual earner couples during pandemic. This study investigated the predictor role of core self-evaluation and spousal support through mediating role of work family conflict (WFC) on workplace well-being. Based on the conservation of resources theory, we need to identify essential resource to fulfill workplace well-being. Data were collected from 200 employed Jakarta Metropolitan area (Jabodetabek) dual-earners who had at least one child below the age of 13. According to the mediation with two predictors analysis, the mediating effect of WFC can only predict the linkage between core self-evaluation and workplace well-being (β = 0.02, SE =0.02; 95% CI [0.005, 0.061]) but cannot predict the role of spousal support through WFC on workplace well-being (β = 0.00, SE =0.00; 95% CI [-0.002, 0.007]). This finding explained the importance of self-evaluation during pandemic to enhance workplace well-being and buffered negative effect of work and family related burdens.

Published: May 2021

Relevance. The focus of modern dental treatment not only on the elimination of aesthetic, but also functional disorders requires an understanding of the functional conjugation of the chewing muscles, the possibility of interprognosis of parameters. Objective. Assess the functional relationship between the tone of the chewing muscles proper and the bioelectric activity of the temporal and sublingual muscle groups in children with anomalies of the dentoalveolar system. Materials and Methods. The study involved 36 patients of Childrens Clinical Dental Clinic No. 2 of Voronezh, aged 6 to 12 years, who had not previously received orthodontic treatment and had distal occlusion anomalies. Evaluation of the bioelectric activity of temporal and sublingual muscles was carried out using surface electromyography on the Electromyograph Dental apparatus (Taganrog, Russia), the Chewing General sample. Evaluation of the tone of the chewing muscles proper was carried out using the Mioton-3C device in a state of physiological rest of the lower jaw. Statistical processing was carried out using Microsoft Excel, version 7.0 and the statistical programs SPSS Statistics 21 and STATISTICA 7. Results and Discussion. Correlation analysis revealed the presence of 4 weak positive, 2 weak negative, 14 moderate positive, 3 moderate negative, and 1 noticeable positive correlation between the tone of the right chewing muscle proper and the parameters of the bioelectric activity of the right and left temporal and sublingual muscles. Correlation analysis revealed the presence of 5 weak positive, 7 weak negative, 9 moderate negative correlations between the tone of the left chewing muscle proper and the parameters of bioelectric activity of the right and left temporal and sublingual muscles. Conclusion. A greater effect of the tone of the right chewing muscle on the bioelectric activity of temporal and sublingual muscles was found compared to the tone of the left chewing muscle itself. 27 equations have been derived that can be used as predictive models for calculating the tone of right and left chewing muscles proper depending on the indicators of bioelectric activity of temporal and sublingual muscles.

Relevance. The consumption of caffeine-containing food in the modern world must necessarily be safe for humans, including should not affect the hereditary material of the body. Objective: to determine the possible effect of caffeine at the cytogenetic level by the micronucleus method on erythrocytes. Materials and Methods. The objects for the study were non-linear mice, which were divided into 6 groups - one control group and 5 experimental groups. The first experimental group and the second in the experiment received caffeine in doses of 40 mg/kg and 100 mg/kg.The control group received saline. Caffeine was administered orally. The mutagen (dioxidine) was injected intraperitoneally. On the 5th day of the experimental study, we performed blood sampling for cytogenetic analysis. Results and Discussion. Our study of the caffeine preparation made it possible to determine the following patterns. Firstly, when administered within 5 days, caffeine at a dose of 40 and 100 mg/kg did not cause an increase in the number of micronuclei in erythrocytes in mice. Secondly, the combined use of caffeine (both at a dose of 40mg/kgand at a dose of 100 mg / kg) and dioxidine significantly increased the level of micronuclei in comparison with the control group. Thirdly, caffeine at a dose of 40mg/kgdid not increase the mutagenic activity of dioxidine, but a dose of caffeine of 100mg/kgwhen combined with a mutagen led to a significant increase in the level of cytogenetic damage. Conclusion. According to our data, caffeine in the experimental study was not a mutagen, but at a dose of 100 mg/kg it represented a comutagenic effect.

Authors: Kim Natalya N.
Published: May 2021

Historical policy was one of the main directions of the domestic policy of the Roh Moo-hyuns government (2003-2008). The ideological justification of revising the 20th century history of Korea was the idea of building a new Korean society based on the principles of democracy and the rule of civil rights and freedoms. Through the implementation of a new historical policy the Roh Moo-hyuns government tried to prove that the creation of such a society was impossible without revealing the truth about the historical past, in which the state repeatedly neglected civil rights and committed crimes. Increased attention to issues of restoration of the historical justice is typical for the current government of Moon Jae-in, the political successor of Roh Moo-hyun. Based on the analysis of the governmental documents, legislation this paper reveals the main disagreements between political parties of the Republic of Korea around the establishment of the Truth and Reconciliation Commission, identifies the key results of its activities.
North Korean Posters as a Mean of Propaganda
Authors: Vorobeva Anastasia K. , Ragozina Sabina S.
Published: May 2021

Propaganda is an attempt to spread social and political values to influence peoples thinking, as well as to control and shape their behavior. It is an inseparable tool of the North Korean state. In a totalitarian state where digital information is restricted, the standards of living are low, and access to education is limited, propaganda is a part of almost all everyday routines. Its key function is to support the existing regime and teach citizens to obey it. Drawing on semiotic methodologies, this article examines North Korean propaganda through the prism of visual art and identifies distinctive features of posters as one of the major elements of the complex system of North Korean propaganda. The relevance of this work lies in the permanent interest in the phenomenon of North Korean propaganda in the international arena. The purpose of this work is to study the distinctive features and characteristics of propaganda posters as an integral part of North Korean propaganda. The objectives of this work are a detailed consideration of the propaganda system, its distinctive features, structuring of campaign posters, slogans, and messages with their accompanying translation, embedded within this type of propaganda.

Aim: In Traumatic brain injury (TBI) patients, a complex cascade of
inflammatory responses is frequently observed following trauma. Numerous
dietary agents have long been found to have potential in modulating
inflammatory responses. This pilot study, designed an enteral formula
with low inflammatory properties based on the dietary inflammatory index
(DII®) and evaluated its effect on inflammatory and metabolic factors in
critically ill TBI patients. Methods: This Single-blind randomized
controlled pilot study conducted at the Neurosurgical ICU of Shahid
Kamyab Hospital (Mashhad, Iran). A total of 20 TBI patients were
randomly assigned to receive either low-DII-score or standard formula at
the Intensive Care Unit (ICU). The primary outcomes of the study
included clinical status, inflammatory biomarkers, APACHE II, SAPS II,
SOFA, and NUTRIC scores. Results: The trial groups did not differ
significantly on baseline values. Following 14 days of intervention,
there was a statistically significant decrease in the APACHE II, SAPS
II, and NUTRIC scores and a significant increase in GCS score in the
low-DII-score formula group compared to the standard formula group. Over
two weeks, high sensitivity c-reactive protein (hs-CRP) values -2.73
(95% CI: -3.67, -1.79) mg/dL in the low-DII-score formula group vs.
0.65 (95% CI: -0.29, 1.58) mg/dL in controls. Moreover, the length of
hospital stay was longer for the standard formula group than for the
low-DII-score formula group. Conclusion: The low-DII-score formula
improves inflammatory factors (serum hs-CRP) and metabolic biomarkers
(LDL-c and FBS). Furthermore, clinical outcomes, including the length of
hospital stay and disease severity appear to be enhanced.

Published: May 2021

Additive manufacturing (AM) enables the cost-effective production of
complex components, many of which are traditionally manufactured using
costly production steps among other processes. One widely applied AM
process is Laser-based Powder Bed Fusion of Metals (PBF-LB/M); however,
internal pores and rough surfaces are typically inevitable with
PBF-LB/M, reducing fatigue and corrosion resistance compared to
traditional processes involving turning and milling. Additionally, large
defects often occur near to or just at the surfaces. Thus, this study
investigates the effect of hybrid additive and subtractive manufacturing
on the fatigue strength of AISI 316L. For this purpose, different post
treatment routes are compared with wrought material. Additionally,
computer tomography is used to determine the necessary machining depth
of the surface layer. In this study, heat-treatment and machining are
both found to significantly increase fatigue strength. Finally, cyclic
mean stresses affect wrought and AM specimens differently.

Authors: Wang Hongxia , Luo Xuehong , Ling Long
Published: May 2021

We consider a new class of semiparametric spatio-temporal models with
unknown and banded autoregressive coefficient matrices. The setting
represents a type of sparse structure in order to include as many panels
as possible. We apply the local linear method and least squares method
for Yule-Walker equation to estimate trend function and spatio-temporal
autoregressive coefficient matrices respectively. We also balance the
over-determined and under-determined phenomena in part by adjusting the
order of extracting sample information. Both the asymptotic normality
and convergence rates of the proposed estimators are established. The
proposed methods are further illustrated using both simulation and case
studies, the results also show that our estimator is stable among
different sample size, and it performs better than the traditional
method with known spatial weight matrices.

Authors: Vadivel R , Srinivasan Sabarathinam , Wu Yongbao , GUNASEKARAN NALLAPPAN
Published: May 2021

The bifurcation, stability and stabilization analysis of permanent
magnet synchronous motor (PMSM) systems are investigated in this paper.
To begin, a new class of delay-dependent sufficient conditions is
suggested with respect to the information of the membership function, a
relevant Lyapunov-Krasovskii functional (LKF), and the overall
information connected with the real sampling pattern, so that the fuzzy
system is ensured to be stable with a weighted dissipativity efficiency.
Second, sampled-data control is intended to stabilize the Takagi-Sugeno
(T-S) fuzzy system with specified integral inequalities based on the
obtained results. The required conditions are stated in terms of the
feasibility of linear matrix inequalities (LMIs) under the dissipativity
output index, and can readily be verified by MATLAB toolbox. Finally,
verification examples are contributed to demonstrated the efficacy of
the techniques established in this paper.
New and more dual-mode solitary wave solutions for the Kraenkel-Manna-Merle system incorporating fractal effects
Authors: Raza Nauman , Hassan Zara , Butt Asma , Rahman Riaz , Abdel-Aty Abdel-Haleem
Published: May 2021

This paper introduces the fractal Kraenkel-Manna-Merle (KMM) system,
that explains nonlinear short wave propagation with zero conductivity
for saturated ferromagnetic materials in an external field. The semi
inverse technique and the new auxiliary equation method (NAEM) are used
to generate a new set of solutions. The proposed methods are more
straightforward, succinct, accurate, and simple to calculate dual mode
solitary wave solutions. A collection of exact soliton solutions
specifically bright, dark, singular-shaped and singular-periodic are
generated. The estimated solutions are obtained using constraint
conditions and are displayed through 2D, 3D and contour plots with
appropriate parametric values. The arbitrary functions in the solutions
are chosen as unique functions to generate some novel soliton
structures.
Effect of different carbon sources on vacuum carbothermal reduction of low-grade phosphorus ore
Authors: He Xuan , Huang Run
Published: May 2021

In this study, the effect of different carbon sources on the carbothermal
reduction of low-grade phosphate ore were examined using FactSage7.2
calculations and vacuum reduction experiments. The thermodynamic
calculations showed that the trend of the effect for three types of reducing
agents was generally consistent under 1 Pa pressure and 14% carbon dosage.
The reduction effect was maximum when graphite was used as the reducing
agent, and a maximum mass of P was obtained at 1250 ?C. The vacuum
experiment results showed that the reduction and volatilization ratios of
phosphate rock increased with temperature for different carbon sources.
Maximum reduction ratio was obtained using graphite in the temperature range
1250-1300 ?C. The reduction effect of pulverized coal was optimal at 1350
?C, when SiO2, Al2O3, and MgO in the pulverized coal ash were exposed to
form low-melting eutectics with CaO due to the increased degree of reaction,
and the heat and mass transfer rates were increased. At this time, a maximum
reduction ratio of 51.77% of the sample and a maximum volatilization ratio
of 82.44% of P were achieved. Considering the cost effectiveness, pulverized
coal was the optimum carbon source for the treatment of low-grade phosphate
rock using vacuum carbothermal reduction.
AISI 304 Paslanmaz Çelik Sac Malzemelere Temper Haddeleme ile Pürüzlülük Transferinde Haddeleme Parametrelerinin Etkisinin İncelenmesi
Authors: ÖZAKIN Batuhan , KURGAN Naci
Published: May 2021

Sac malzemelerin yüzeyleri, boyanabilme ve şekillendirme açısından belli bir pürüzlülük profiline sahip olmalıdır. Yüzeyin pürüzlülüğünün az olması boya veya kaplamaların yapışmasını azaltabileceği gibi fazla olması boya veya kaplamanın yetersiz olması sonucunda paslanmaya neden olabilecek ayrıca boya veya kaplamanın fazla kullanılmasına sebep olarak maliyetlerin artmasına sebep olacaktır. Bu sebeplerden dolayı, sac malzeme yüzeyinin en uygun seviyede pürüzlülüğe sahip olması istenir. Sac malzemelerin yüzeylerine genellikle temper haddeleme olarak bilinen, özel pürüzlü merdanelerle pürüzlülük profili transfer edilir. Sac malzeme yüzeyine aktarılan pürüzlülük profili, haddeleme parametrelerinden etkilenir. Bu deneysel çalışmada otomotiv endüstrisinde yoğun bir şekilde kullanılan yüksek akma mukavemeti ve uzama kabiliyetine sahip olan AISI 304 paslanmaz çelik sac malzemelere temper haddeleme ile pürüzlülük transferine ezme miktarı, haddeleme hızı, merdane pürüzlülüğü, yağlama koşulları ve malzeme kalınlığının etkisi araştırılmış ve pürüzlülük dağılımı malzeme oranı eğrileri yardımıyla değerlendirilmiştir. Ezme miktarı arttıkça pürüzlülük transfer oranı arttı. Yağlayıcı kullanılan koşullar altında, merdane pürüzlülüğü, malzeme kalınlığı artışıyla birlikte pürüzlülük transfer oranı azaldı. Haddeleme hızının artışı pürüzlülük transfer oranına etkisi olmadığı sonucuna varıldı. Ayrıca düşük ezme miktarı, düşük haddeleme hızı, düşük pürüzlülüğe sahip merdane, kalın malzeme ve yağlı koşulların tercih edilmesi ile daha homojen bir pürüzlülük dağılımına ulaşılabileceği sonucuna varılmıştır.

Authors: ÖZÜPAK Yıldırım
Published: May 2021

High currents occurring in transformers in transient state may cause the insulation materials to deteriorate. In this paper, the effects of the capacitance values between the winding and the core and between the windings on the transition of the lightning strike applied to the secondary side to the primary side of power transformers were analyzed. Transformer models were created in ANSYS@Maxwell-2D environment, which realizes a solution based on Finite Element Method (FEM). In simulation studies, a lightning impulse voltage of 1/100 µs was applied to the secondary side of the transformer with a special method. It has been observed that the change of the values of the capacitances between the windings in power transformers affects the amplitude of the primary lightning impulse voltage. With this study, the weak points of the insulation materials of transformers windings were determined and the electric field distribution was analyzed.

"The Relationships between Coping Mechanisms, Depression,
Anxiety and Sleep Disorders in Cardiovascular Patients"
Authors: MUSTAȚĂ Andreea E.
Published: May 2021

"Depression, anxiety and sleep disorders are psychological risk factors that
could impact the quality of life in cardiovascular patients. In this study, a
theoretical model on the complex relationships between coping mechanisms,
depression, anxiety and sleep disorders was studied in a sample of 274
cardiovascular patients. The maladaptive cognitive-emotional coping
strategies that appeared to be correlated with these negative emotional
pathologies were self-blaming, ruminating and catastrophizing, and the
adaptive ones were positive refocusing, refocusing on planning and positive
reassessment. A theoretical model that explains these relationships at a
process level appears to have statistical significance and to have adequate
goodness of fit. In this model, there are statistically significant direct effects
of maladaptive and adaptive coping mechanisms on depression and anxiety,
a significant effect of anxiety on depression, as well as statistically
significant positive effects of depression and anxiety on sleep disorders. The
age has been controlled for in the model and the severity of the illness
appears to have a moderating role in this context, with a stronger effect of
anxiety on depression for patients with more severe illnesses. The practical
implications of these results in psychological counselling addressed to
cardiovascular patients are discussed."
Cambios de usos del suelo en la periferia del área metropolitana de Buenos Aires. Aportes para una teoría de la rent gap periurbana
Authors: Apaolaza Ricardo , Venturini Juan Pablo
Published: May 2021

Desde mediados de la década del 1990 se observa una fuerte expansión de urbanizaciones cerradas en las periferias metropolitanas de Buenos Aires, que avanzan sobre áreas ambientalmente frágiles, como humedales y suelos deteriorados por actividades extractivas. El diferencial entre la renta real de estos suelos y la alta renta potencial vinculada al uso residencial para sectores de ingresos altos tiende a ser capturado como una ganancia extraordinaria, y representa por ende un fuerte estímulo para la (re)inversión de capital y el avance inmobiliario. A través de análisis satelital y geoestadístico, el presente trabajo problematiza algunas de estas dinámicas, valiéndose de la hipótesis de un ciclo de cambios secuenciados en el uso del suelo tendiente a conformar una brecha de renta periurbana (o peri rent gap), con lo que se traza un paralelismo con la conocida teoría de Neil Smith.
Envejecimiento demográfico y escenarios de vulnerabilidad urbana: ¿Hay siempre una relación conexa? Estudio de casos en las ciudades de Sevilla (España) y La Plata (Argentina)
Authors: Valle Ramos Carolina del , Goicoechea María Eugenia
Published: May 2021

El envejecimiento poblacional se presenta como un fenómeno demográfico actual, consolidado en las ciudades tanto europeas como latinoamericanas. No obstante, los índices de envejecimiento se distribuyen de manera desigual al interior de estas, suponiendo un diálogo particular con las áreas de vulnerabilidad urbana. El objetivo del artículo es mostrar la evolución reciente del proceso de envejecimiento demográfico urbano y su desigual distribución socioespacial en las ciudades de Sevilla (España) y la Plata (Argentina), analizando, en perspectiva cuantitativa comparada, su relación con los escenarios de vulnerabilidad social y habitacional, ya que ello podría conllevar procesos de riesgo. La metodología utilizada es cuantitativa, centrada en análisis de fuentes estadísticas oficiales (censos, padrones, catastro). Los resultados obtenidos evidencian la importancia de considerar al envejecimiento demográfico como un estadio final del ciclo de vida del barrio, más que como condicionante en la vulnerabilidad urbana.
Los poderes emergentes en la política internacional de comienzos del siglo XXI: el caso de Brasil como potencia suramericana
Authors: De Benedictis Marco
Published: May 2021

En el presente artículo se analizarán los cambios que han llevado a la irrupción de los poderes emergentes en la geopolítica global. Se centrará el análisis en los países BRICS en una primera instancia y luego se enfocará la atención en el caso de Brasil, para comprender cómo este contexto impactó en América del Sur y qué cambios se dan en el contexto actual. Lo que se demostrará es que estos países lograron consolidar su posición internacional a partir de su peso a nivel regional, pero sus objetivos no estaban vinculados a un cambio sistémico de la política global, sino a obtener un lugar de relevancia en las decisiones mundiales.
Conflictos (y ausencia de conflictos) en las relocalizaciones del Matanza-Riachuelo. Reflexiones preliminares en un municipio de la cuenca media
Authors: Olejarczyk Romina
Published: May 2021

En este artículo reflexiono sobre los conflictos que se suscitan en las relocalizaciones de la cuenca Matanza-Riachuelo. La categoría de conflicto –que ha sido ampliamente desarrollada en el campo de las ciencias sociales– opera, a su vez, como un término nativo utilizado, principalmente, por los decisores y ejecutores de esta política pública. Por un lado, esta categoría nativa hace referencia al “gran conflicto” inaugural de la causa: la problemática ambiental en Villa Inflamable. Por otro lado, es utilizada para realizar una distinción entre “territorios conflictivos” o “territorios ausentes de conflictos” con los que, en consecuencia, es posible articular (o no) las acciones de esta política. Presentaré los avances de un incipiente trabajo de campo de corte cualitativo en el municipio de Almirante Brown para dar cuenta de la multiplicidad de conflictos que transcurren en las trincheras de esta política pública.
The Abject in T. S. Eliot’s The Waste Land
Authors: Elahi Eyesha
Published: May 2021

T. S. Eliot’s monumental poem, The Waste Land, discusses hopelessness and desolation and shuns them at every turn. The speakers spurn it and despair at the desolate state of humankind and society. This paper aims to read T. S. Eliot’s The Waste Land in light of Julia Kristeva’s theory of abjection and Jacques Lacan’s notion of jouissance. The main claim is that despite the apparent horror of desolation, the more the poem tries to repel desolation, the more it cannot help but repeatedly allude to it, as if unwillingly drawn to it, so that death and desolation are not the subject, nor are they the object, but rather the abject of the poem. The sections of the poem I feel are most relevant for such an analysis are “The Burial of the Dead” (lines 1-30) and “What the Thunder Said” (lines 322-375).
Review Essay: The Beginnings of Civilization
Authors: Clemens, Jr. Walter C.
Published: May 2021

What can contemporary social scientists learn from ancient history? Key features of modern civilization began in the fertile crescent of today’s Middle East many thousands of years ago. Thanks to geography and other factors, these innovations spread—east and west. Not just agriculture and engineering but monotheistic religion and alphabetic writing took root there. Parallels to or offshoots of Sumerian culture emerged in the Indus River, Persia, and Egypt. Their distinctive ways of life took shape, waxed, and then waned. Social scientists who try to keep up with a world in turmoil by listening to the BBC or reading Le Monde may be tempted to ask: “How did all this begin and where are we going?” The Singapore-based political analyst Parag Khanna answers: “Asia.” Civilization began in Western Asia and is now being shaped by “Asianization” of the planet. (See Khanna, The Future is Asian, 2019). Whether or not Khanna’s hypothesis about the future proves correct, the importance of Western Asia in global history is documented in the books Uruk and Mesopotamia.
Book Review: Ryan Gingeras, Eternal Dawn: Turkey in the Age of Atatürk, Oxford: Oxford University Press, 2019.
Authors: Altinkas Evren
Published: May 2021

This book analyses the transformation from the late Ottoman period to the modern Republic of Turkey with a focus on Mustafa Kemal Atatürk and the reforms implemented during the early years of the republic. The book familiarizes the readers with the political, social and economic transformation of the country by focusing on specific cases and examples with a comprehensive historical background. Gingeras focuses on the historical background of major topics (e.g. Reforms, Kurdish Revolts, Turkish Nationalism etc.) in the early Republic of Turkey and connects them with the developments in the late Ottoman Empire. This book is different from previous works because it emphasizes the relations between the new state and the people in Anatolia.
POSSIBLE OUTCOMES OF BREXIT FOR EUROPEAN UNION DEVELOPMENT
Authors: Kaveshnikov N. Y.
Published: May 2021

The article discusses some implications of the Brexit referendum for institutional and political development of the European Union and for relations between the EU and the UK. The most obvious consequence of the referendum is the collapse of ideology of continuous and progressing development of integration. Instead of endless, irreversible, a priori beneficial for everyone integration process, the European Union has become an organization that does not have a Messianic goal and obliged to prove its usefulness in everyday life. EU systemic crisis will inevitably lead to a profound transformation of its institutional and political structure. After the British referendum, only two options are possible. First of all, partial deconstruction of the European Union. The idea that European integration has gone too far lies in the basis of this strategy. According to this logic, the single market is the main EU achievement. Return to the basics - this is a pragmatic approach to integration, which should replace attempts to fix rotten projects (like Euro) or to achieve the unattainable (political Union). This option is hardly probable. Second option is transformation of the EU into the "core and periphery" system having the basis flexible integration. Over the past 20 years, flexibility transformed from temporary phenomenon into a permanent and formalized mechanism; its elements exist in many EU politics. Brexit would be able to accelerate significantly the formation of a cohesive core within the Eu. The core will not be homogeneous; it will include as governing structures: the German-French axis and a group of EU founding countries.

In this study, dichloromethane, acetone, and methanol extracts of the aerial parts of the Salvia marashica plant which is an endemic species to Anatolia, were investigated. The total phenolic amounts of these extracts were determined as pyrocatechol equivalent and total flavonoids as quercetin equivalent. Antioxidant activity was determined by four complementary methods including inhibition of lipid peroxidation (by β-carotene color expression), DPPH free radical scavenging activity, ABTS cation radical scavenging activity and CUPRAC methods. Anticholinesterase activity of the extracts was investigated by the Ellman method against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Viability and cytotoxic activity tests were carried out on the fibroblast L929 cells and cytotoxic A549 lung cancer cells, respectively. The triterpenoids and diterpenoids constitute the major secondary metabolites of the S. marashica acetone and methanol extracts isolated by chromatographic methods. Their structures were determined based on spectroscopic methods, namely NMR and mass analyses. Ten terpenoids were obtained from either acetone or methanol extracts of the S. marashica. Seven of them were triterpenoids, elucidated as lupeol, lupeol-3-acetate, lup-12, 20(29)-diene, lup-20(29)-ene, α-amyrin-tetracosanoate, oleanolic acid and ursolic acid besides a steroid β-sitosterol. Two abietane diterpenes, abieta-8,11,13-triene (1) and 18-acetoxymethylene-abieta-8,11,13-triene (2), were obtained from the acetone extract which were isolated from a Salvia species for the first time in the present study. The methanol extract was found to be very rich in rosmarinic acid determined by LC-MS/MS analysis.
Some aspects of the evolution of the legal regulation of the right of citizens (population) to participate in the administration of justice in Russia
Authors: Shikhovtsova Albina Olegovna
Published: May 2021

The article considers the evolutionary transformation of securing the right of citizens to participate in the administration of justice. The author has carried out a detailed analysis of the origins of the birth of the right of citizens to participate in the administration of justice and formulated the main results of the development of the legislative consolidation of this right by referring to the analysis of legal acts of various historical stages and a comparative legal study of the experience of regulating this issue. In the course of the research, the author focuses on the evolution of the forms of citizens' participation in the administration of justice, the understanding of the citizen's competence in this area, the relationship with other political rights and freedoms of citizens. The author comes to the conclusion that the legislative consolidation of this right has a direct relationship with the social standards of a certain historical stage. The key aspects of the historical and legal development of the institution of citizens' participation in the activities of the courts can rightly be considered: - recognition of the fact of society's participation in the implementation of justice; - recognition of the institution of citizens' participation in the activities of the courts as a component of society; - registration of the institution of citizens' participation in the activities of the courts from the institution of society to a full-fledged component as part of state power;"- complication of the configuration of the circle of subjects of legal proceedings from the involvement of individuals as assessors directly in the court to the establishment of the right of these subjects to participate directly in the administration of justice. The author's approach to highlighting the forms of evolution of the legal regulation of the right of citizens to participate in the work of the judicial system seems to be original.
