Socialist Realism as Cancel Culture for the Bulgarian Scenographic Practice
Authors:   Theatre Institute, Bulgarian Academy of Science, Tagareva Albena
Published: April 2023

The paper presents some emblematic examples from Bulgarian theatrical history, in which the culture of rejection has been ruthlessly applied even to artists loyal to the regime. One of the most significant ones is with scenographer Svetoslav Genev. For the first time in the history of Bulgarian theatre, a set designer became a managing director. He rose to this position thanks to his personal qualities and ambition as well as to the strong Communist connections his family had. During the period of his directorship, he created one of the most impressive designs for a theatre performance, rejecting Socialist Realism as an official method in arts. Despite his strong positions in Communist Pary, after the Prague Spring everything, he was largely thrown out of public life.
Création artistique et culture de l’effacement en ligne et à Chypre
Authors:   University of Cyprus, Christofi Christakis
Published: April 2023

The intensification of cancel culture is increasingly related to the expansion of the Internet and the impact of social media networking. It defines public debates or controversies, shared online, hard discourses that cancel a social phenomenon, an individual or his work. However, artistic expression and cancel culture, both closely connected to various cultural activities and online habits and practices, present dynamic interactions on the Internet. Artistic creation and cancel culture appear as standpoints that allow us to examine the limits of the freedom of online expression. Since they are both critical and political acts, they also help to question the sub-tle link between the individual and public perceptions. We will attempt to approach these questions through specific examples of worldwide and Cypriot events that sometimes show complicity and sometimes rivalry between artistic creation and cancel culture.

For any country, value of its currency is considered as one of the major indicators of its economy. In the current global economic scenario where presence of several events plays vital roles in changing the value of any nation’s currency, many governments, corporate houses are concerned about the volatility of the value of their currency. The Currency depreciates when the worth of a country’s currency drops significantly compared to other currency. There are various impact of currency depreciation ranging from micro level such as inflation, Low performance of Industry/Sector, to macro level such as negative growth rate of GDP, economic instability, Even impacting Global economy by disrupting interrupting international trade. The approach involves gathering insights from previously published research papers and articles as well as from watching recorded interviews from professionals in the field of the topic. Also, data from the government websites are being used to get comprehensive answer. As all the data have been taken from secondary sources so there is no requirement for conducting survey. The main agenda of this research paper is to study different factors that causes the volatility of the currency and analyze the impact of the currency depreciation on the economy and different variables that contribute in currency losing its value. The paper provides brief insight on depreciation of currency and its causes. The research also explains different factors (monetary and non-monetary) such as inflation, interest rates, government policies and how those variables affect the value of the currency. Also, with the causes this paper sheds light on the consequences (monetary and non-monetary) such as rise in cost of imported good, Negative balance of trade, Impact in balance of payment, reduced foreign investment, reduced tourism and how various sector of economy acts simultaneously with decrease in value of the currency. Also, with changing landscape of the economy, the policymakers and investors must be alert and be prompt with their decision making in order to make their companies and country stay afloat. The paper helps various investors and policymakers with insights and recommendation on how policy makers and investors should manage the risk and opportunities that comes with the depreciating currency

Published: April 2023

Sexual violence is a serious social and public health problem affecting the health of women (DeGue et al., 2013). Forced marriage is a form of sexual violence according to law number 12 of 2022 concerning criminal acts of sexual violence in Indonesia hereinafter referred to as the TPKS Law. This study aims to find out and examine the settlement of the practice of Capture Marriage based on the theory of gender equality. This research is an empirical legal research with a legal sociology approach. The results of the research show that in the process of resolving the Capture Marriage case, the community always chooses to resolve it according to custom, although there are some who report to the police, it does not run to completion but stops in the middle of the process. The Capture Marriage case itself shows that there is no gender equality due to the dominating patriarchal culture and the settlement process in Central Sumba is not in accordance with the theory of protection and law enforcement because law enforcement officials tend to ignore the interests of victims and are more subservient to custom.

The crisis due to the Covid-19 pandemic should be able become the momentum for the Indonesian people to make changes. Mainly by developing new habits that are in line with technological advances. The Covid-19 pandemic must be seen as an opportunity so that the Indonesian economy is more globally competitive with the demands of technological progress. The Covid-19 pandemic has made Indonesians master virtual learning as well as running an online business. Learning online and running a business also digitally. Social media has emerged as the dominant digital media platform in contemporary society. The rapid development of social media has driven changes in the way people interact. The use of social media has a huge influence on public relations, marketing. Therefore, the concept of mobilization is their strategy to reach consumers with an increasingly networked platform, (Pradhan & Kumar, 2015). With the use of social media as a new marketing tool that helps consumers to get information and interact with others on the Web. The concept of online mobilization mix, which is abbreviated as SHARE, is storytelling, hype, actionable, relevant, and emotional. In the new model of the business world, entrepreneurs are asked to ride the tide, not against it, as today, many startups can take advantage of successful unicons by intelligently mobilizing their business to netizens to promote their business Implementation of Mobilization and Orchestration strategies, by mobilizing the use of technology to match supply with the demand for various agricultural products more optimally from the farmers. In the hyperconnected era, extraordinary greatness is no longer required, but sufficient mobilization skills (Online Mobilization Mix, SHARE, which is sufficient to mobilize). Based on the results obtained, it can be explained that the R-Square effect value is 0.791, meaning that the orchestration variable can explain the Mix Mobilization Model of 79.1%, and the remaining 20.9% is influenced by other variables not included in this study

Published: April 2023

Introduction. There are considered drinking and mineral waters in terms of homeostatic action (hormesis) of water-soluble silicon and the trends of its biological activity and possible negative effects on the human body.
Materials and methods. In studied waters the concentration of the systemic homeostatic regulator – peroxide anion-radical was measured by the kinetic chemiluminescent method. The water biological activity was assessed by the extrasubstrate synthesis of adenosine triphosphate by the ATP synthase of microorganisms E.Coli K12 TG1(pF1) with built-in genes for the complete CDABE lux operon of the bacteria V. fischeri 6E luminescent system. The parametrization of the water structural-energy state was carried out according to the cryophysical capillary technique. The study object were low-mineralized drinking water packed in 9-liter polymer containers with an initial silicon content of 12 mg/dm3.
Results. The hormetic effect of silicon waters due to self-induction of peroxide anion radicals in water manifests itself in the form of mitochondrial activity and enzyme complexes stimulation, accompanied by activation of the central nervous system, maintenance of nonspecific immunity, and the reproductive system functioning. The degree of silicon water beneficial effect due to the electron-donor and regulatory action of peroxide anion-radicals associates, depends on activation processes during the production and drinking water storage.
Limitations. Recommendations for maintaining the biological activity of silica waters do not go beyond the limits established by existing regulatory documents on the safety of drinking waters.
Conclusion. The levels of radical anion peroxide production (2.6–5.2 μg/dm3), obtained in the course of this study, correspond to the maximum changes in the biological activity of water activation in the range of 1.4–3.0 (relative to the control – distilled water) in the mode of implementing the conditions of non-local activation. With long-term storage in a polymer container, the ability to activate is lost – such water becomes biologically inert.

Authors: Shelomentsev Ivan G. , Gomzikova Ekaterina A.
Published: April 2023

Introduction. Control of distribution of aerosol particle by size in the workplace area is one of the important problems of hygiene. To assess health effect of aerosol particles in workers, it is necessary to improve existing and introduce new methods for analyzing the dispersion and chemical composition of aerosols, including their nanosized constituents.
Materials and methods. Generated lead oxide nanoparticles with an average diameter of 26.2±12.6 nm were sampled on 47-mm nylon membrane disc filters with a pore size of 0.2 µm and 1.2 µm. The experimental device represented a cascade system consisting of two membrane filters, where the first filter was intended for capturing nanoparticles while the second one was used for establishing the capture efficiency of the first. The sampling time for the cascade systems was 5, 10, 15, 20, 40, and 80 minutes for filters with a pore size of 0.2 µm and 5, 10, 20, and 120 minutes for those with a 1.2 µm pore size; in all cases, the volumetric flow rate was 1.5 L/min. The membrane surface was then analyzed by scanning electron microscopy.
Results. Lead oxide nanoparticles were found on all filters tested. They were evenly distributed over the entire effective filter area, their number increasing with air sampling duration. No nanoparticles were observed on the second level filters, regardless of the sampling period.
Limitations. The results cannot be extrapolated to all types of nanoparticles since the capacity of polyamide/nylon filters was studied only with respect to lead oxide nanoparticles.
Conclusion. The study proved that polyamide/nylon filters with the pore sizes of 0.2 µm and 1.2 µm have a high potential for nanoparticle capture and can be considered as a tool for developing new techniques of studying and controlling harmful factors.

Biological effects of exposure to copper nanoparticles: markers of exposure
Authors: Ruzakov Vadim O.
Published: April 2023

Introduction. Aerosol nanoparticles at operating metallurgical plants are potent of the significant risk factor that needs to be studied. The purpose of the work was to study biological effects of exposure to copper nanoparticles compared to microparticles and identify potential markers of the exposure. Materials and methods. Two experimental groups of rats, twelve animals each, were subchronically exposed to copper-containing nanoparticles and microparticles injected intraperitoneally. Changes in their biochemical parameters, tissues, and organs were then compared to those in the control rats administered with deionized water. During periodic medical examinations of workers occupationally exposed to copper-containing aerosols with different particle size distribution, additional laboratory and instrumental methods of testing were used to identify possible exposure effects to health manifested by changes in biochemical parameters. Results. The experimental study showed that in liver, the exposure to copper nanoparticles, compared to microparticles, induced a more significant inhibition of replication of hepatocytes in regeneration, as demonstrated by the number of binuclear cells, and an increase in the number of Kupffer cells (tissue macrophages), while in kidney, it caused a more pronounced convoluted tubule brush border loss. The exposure to both micro- and nano-sized copper particles was found to induce pathological changes in neurons of the ganglionic layer of the cortex and basal nuclei. Test results showed a significant increase in the blood concentration of ceruloplasmin in the core personnel of the metallurgical plant following the exposure to copper aerosols rich in nanoparticles. Limitations. The assessment of the results of the impact of copper nanoparticles in the composition of the aerosol on the health of 224 employees of the enterprise and the results of the experiment obtained on 36 animals corresponded to the current social and ethical standards and norms. Conclusion. Specifics of the exposure to nanoparticles require a revision of approaches to regulating aerosols with account for particle size distribution.

Objective. To evaluate the degree of incomplete revascularization in patients with multiarterial coronary artery disease who underwent percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG) using the Syntax revascularization index (SRI) and its relationship to major cardiovascular events during follow-up. Materials and Methods. Observational, retrospective study with 4-year follow-up of patients with multiarterial coronary artery disease who underwent surgical or percutaneous coronary revascularization, in whom the baseline Syntax score (SSb) and the residualSyntax score (SSr) were calculated. The Syntax Revascularization Index (SRI) was determined withthe following formula: SRI = (1- [SSr/SSb]) x 100, and major cardiovascular events at 4-year follow-up were compared. Results. Two hundred patients (100 in each group) were evaluated. Mean SSr in group 1 was 83.2%, and in group 2, 79.0% (p=0.88). Mean complete revascularization was 41% in the first group and 35% in the second. A cutoff point of ≤90% of IRS had the best accuracy for predicting major cardiovascular events (area under the curve of 0.60; 95% CI: 0.49-0.71, p<0.05). In multivariate analysis IRS was an independent predictor of major cardiovascular events (HR 2.6; 95%CI: 1.32-3.22, p= 0.043). Conclusions. The Syntax Revascularization Index may be useful for measuring the degree of revascularization in patients with multiarterial coronary artery disease treated percutaneously or surgically. An SRI ≥90% may be an acceptable target for revascularization.
Three Predictions of Gravitational Waves, and Black Holes
Authors: Chang Yi-Fang
Published: April 2023

Gravitational wave forms a focus of physics, astrophysics and cosmology. First, we propose three predictions of gravitational waves: their observations must be nonlinear waves; velocity of gravitational wave should be slightly higher than the velocity of light; gravitational waves in black holes may emit and be observed. Next, we discuss the analogies of the gravitational and electromagnetic fields, and research some relations between black holes and gravitational waves. Finally, we propose the directed gravitational wave observatories of high-energy astrophysics, as such for the huge black holes in the Galactic center.

Published: April 2023

Nowadays, manholes and its maintenance are the main problem in the metropolitan smart cities. A drainage monitoring system plays a significant role in keeping the towns and cities healthy and clean. The major challenge is to further investigate the condition of manholes on the road. In observation, most of the manhole’s lids were not in the settled emplacement and are in damaged condition. Because of these damaged manholes, there are chances of occurrence of accidents on the road. These damaged manholes will be hazardous to personal safety. If the sewage maintenance is not proper, ground water gets contaminated causing infectious diseases. Blockages in drains during monsoon season causes problems in the routine of the public. Hence, there should be a facility in which it alerts the officials about blockages in sewers, their exact location and about the gas explosion, increase in the water level and temperature level. The goal of this project is to create an effective accident-avoidance system by avoiding open manholes in large cities. This system includes an array of sensors for complete monitoring of the manhole cover such that many accidents can be prevented. This system reduces the work of manpower and increases the safety and speed of work. The working and implementation of this project will be very useful to take necessary actions and maintain the regularity of the municipal society
The Context of Remembering
Authors: Leksana Grace T.
Published: April 2023

This chapter is intended to introduce the context in which memories of
violence are formed. This context is a village called Donomulyo, which has
undergone different state transformations. I will scrutinize the structural
influence of those transformations on life in Donomulyo, particularly the
social inequalities and the clientelistic practices between classes that
evolved historically. Although the state had transformed, the inequality
and patronage relations tend to endure. This continuity occurred not
only because of state penetration in rural areas, but also because rural
elites needed to form alliances with the state to maintain their privileged
position, access, and properties. At the same time, clientelistic practices
exacerbate the inequality in the area, leaving out those who are not
involved in the patron’s circle.
Win the Crown

Published: April 2023

Can we find in the Old English translation of Boethius’s Consolation of
Philosophy an authentic relic of the contours of Alfred’s thoughts about
predestination and free will? This chapter offers a close reading of a paragraph comparing life to a race for a golden crown. The first one to reach
it wins it. This bears a startling similarity to the game young Alfred played
to win his mother’s book. If Alfred is the author of all three fables — this
philosophical fable, the fable of the youngest son who wins the book fair
and square, and the fable of Alfred’s papal anointing, then we can get
much closer to understanding what made Alfred tick than we thought.

El fenómeno de la inmigración, de actualidad permanente en los últimos años, presenta una complejidad de la que son fiel reflejo la reforma legal operada por la Ley Orgánica 4/2000 y las modificaciones de la misma que se han sucedido en corto espacio de tiempo. La doctrina se ha ocupado de analizar los distintos aspectos de la norma y, entre ellos, los que atañen a los derechos sociales de los extranjeros, en particular, el derecho al trabajo y, también, los derechos de Seguridad Social. Sin embargo, en muchas ocasiones, estos últimos se abordan de una manera tal vez excesivamente subordinada a los derechos laborales, cuando, sin duda, presentan una sustantividad propia.
El presente trabajo se centra en los derechos que, a cargo de la Seguridad Social española, corresponden al extranjero inmigrante. Se procede a un estudio de la normativa específica de Seguridad Social, no sólo de la actualmente vigente, sino también de los antecedentes legislativos, al objeto de constatar qué tratamiento se ha dispensado por el legislador al trabajador extranjero.
Sobre esta base, se analiza la incidencia de la LOex 4/2000. En particular, el alcance e interpretación de los preceptos dedicados a la materia de Seguridad Social, su acomodo o encaje con la normativa específica previa y, singularmente, los derechos en materia de Seguridad Social que corresponden al extranjero que presta servicios sin autorización previa. A este respecto se articula la tesis del autor sobre el alcance de tales derechos y se recoge el criterio administrativo de actuación adoptado por el INSS a raíz de la reforma operada en el artículo 36.3 LOex por la Ley Orgánica 14/2003, así como la doctrina jurisprudencial conocida, que es la que se contiene en las sentencias del Tribunal Supremo, Sala de lo Social, de 9 de junio y 7 de octubre de 2003.

The problem of neutralization of production waste is one of the main problems in the disposal of oily filters. Ecologists constantly monitor the state of the environment, but this is not enough. It is necessary to introduce technologies for the rational use of natural resources and develop technological schemes. Thus, a correct and efficient scheme for waste disposal will preserve not only the flora and fauna, but also ensure the normal functioning of human life. The proposed method is effective enough to comply with environmental standards, but at the same time it is a source of exposure to hazardous production factors on personnel, which requires strict adherence to safety standards and rules.

The soursop is a species of tropical fruit well accepted by consumers due to its creamy white pulp and excellent flavor. Currently, Mexico is the largest producer and consumer; however, the agronomic practices in use were established without a systematic knowledge of A. muricata L. phenology. The objective of this work then, was to conduct such a study in two of the main producing regions of Mexico: Tepic and Compostela (both in the state of Nayarit). For this, a total of 20 ungrafted trees were selected and their growth stages described using the extended BBCH-scale (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie). Overall, eight main phenological stages were identified over the course of a year. These were: the development of buds (stage 0), leaves (stage 1),and shoots (stage 3), the emergence of flowers (stage 5), flowering (stage 6), fruit development and maturity (stages 7-8), and senescence of branches (stage 9). In addition, 37 secondary growth stages were also described and quantified. The highest number of vegetative shoots occurred from March-July, 2017 and the biggest increase in floral structures from July–September, 2017. Fruit setting to physiological maturity took an average of 114 days in both Tepic and Compostela, with the most intense defoliation occurring in October, 2017 in the former (Tepic) and in December, 2016 in the latter (Compostela). Hopefully, improved agronomic practices will be established using this information, as well as suitable protocols for future physiological studies.

This article considers the concept of investigative action and search process, the essence of operational and investigative action, the opinions of scientists who conducted research on this subject, ensuring the priority of criminal procedural norms at the stage of referral to court, the criteria by which investigative actions can be distinguished from criminal procedural actions, the place of search and investigative action in the system of other investigative actions. The definition of the search and investigative action is not expressed in the legal documents, and there are some inaccuracies in the correct understanding of the content of this investigative action in investigative practice and its correct application, such incidents occur in cases where in judicial and investigative practice the search should be performed. Differences in the conduct of such investigative actions as inspection, seizure, examination of evidence at the scene of the incident, or testimony are specified in the Law of the Republic of Uzbekistan “On Operative-Investigative Activity”: “Inspection of residential and other places, buildings, structures, land, technical and vehicles” and “Detained persons, their belongings and documents, as well as their vehicles may be inspected in the manner prescribed by law”. Investigative actions, common and different from the procedure provided by Chapter XXI of the Code of Administrative Responsibility, which defines administrative detention, inspection of things and vehicles, confiscation of things and documents, are justified.

Authors:   Academy of Public Administrationunder the President of the Republic of Uzbekistan, Rakhimov Dilmurodjon
Published: April 2023

The article aims to analyze the mechanisms and procedures for recruiting personnel to the positions of the state civil service. The article analyzes the methods of training and selection of personnel for the job groups of the state civil service. According to it, two different procedures for entering the state civil service are distinguished. According to the first regulation, the procedure for the appointment and dismissal of state civil servants belonging to a political group is determined by separate laws and decisions of the President of the Republic of Uzbekistan. According to the second regulation, a competition is held for the state civil service positions related to management and specialist groups. In turn, an internal competition is held for the positions of the state civil service related to management groups, and an external competition is held for the positions of the state civil service related to specialist groups. The article analyzes the procedures of the elections and statistical data of the elections held in 2020-2022. The author researched the National Personnel Reserve system for the formation of managerial personnel. Effective mechanisms of effective use of the National Personnel Reserve have been put forward. Based on the research, a number of suggestions and recommendations have been put forward regarding the improvement of the state civil service staffing system.
ACTIVITIES OF SPECIALLY AUTHORIZED GOVERNMENT BODIES IN THE FIELD OF ECOLOGY IN THE REPUBLIC OF UZBEKISTAN: THEORETICAL AND LEGAL ANALYSIS
Authors:   Tashkent State University of Law, Akhrorov Adkhamjon
Published: April 2023

This article analyzes the concept, purpose, object and system of activities of specially authorized government bodies in the field of ecology. In addition, the scientific opinions of legal scholars on the issues of “public administration”, “government bodies in the field of ecology”, “competencies” and the system of state administration bodies regulating the sphere are analyzed. The author’s definitions of the concepts of “public administration in the field of ecology” and “competence of the state administration body in the field of ecology” have been developed. It is also theoretically substantiated that the competence of these government bodies is of great importance when dividing the system of government bodies regulating the sphere of ecology into 3 types. At the same time, an important aspect in determining the competence of the management body regulating the environmental sphere is to achieve the necessary correspondence between functions and competencies. In this case, first of all, the content of the powers should fully correspond to the content of the functions of the relevant management body, and the scope of the powers of the public administration body should correspond to the scope of the functions performed by it, in relation to each object of control everything should be determined and justified that it should effectively ensure implementation. At the end of the study, the necessity of optimizing the system of competent government bodies that regulate the sphere of ecology in our country is substantiated.

Abstract. This study investigated the accuracy of the random forest (RF)
model in gap filling the sensible (H) and latent heat (LE) fluxes, by using
the observation data collected at a site over rice–wheat rotation croplands
in Shouxian County of eastern China from 15 July 2015 to 24 April 2019.
Firstly, the variable significance of the machine learning (ML) model's
five input variables, including the net radiation (Rn), wind speed (WS),
temperature (T), relative humidity (RH), and air pressure (P), was
examined, and it was found that Rn accounted for 78 % and 76 % of the
total variable significance in H and LE calculating, respectively, showing
that it was the most important input variable. Secondly, the RF model's
accuracy with the five-variable (Rn, WS, T, RH, P) input combination was
evaluated, and the results showed that the RF model could reliably gap fill
the H and LE with mean absolute errors (MAEs) of 5.88 and 20.97 W m−2, and root mean square errors (RMSEs) of 10.67 and 29.46 W m−2, respectively. Thirdly, four-variable input combinations were tested,
and it was found that the best input combination was (Rn, WS, T, P) by
removing RH from the input list, and its MAE values of H and LE were reduced
by 12.65 % and 7.12 %, respectively. At last, through the Taylor
diagram, H and LE gap-filling accuracies of the RF model, the support vector
machine (SVM) model, the k nearest-neighbor (KNN) model, and the gradient
boosting decision tree (GBDT) model were intercompared, and the statistical
metrics showed that RF was the most accurate for both H and LE gap filling,
while the LR and KNN model performed the worst for H and LE gap filling,
respectively.
