Authors: Zhovtenko I.M. , Boginich I.O.
Published: October 2021

In the paper, based on the analysis of operating normative, legal acts and scientific literature the security issues dealing with covert investigative (search) activities using special technical tools on the postal communication network. Currently, the mentioned questions are required in the context of fighting against all types of offences, the amount of which the last years has an increasing tendency. In legislative and department normative legal acts and special literature sufficient attention was paid to the questions of the legislative regulation, organization and application of the special technical tools during realization of covert investigative (search) activities. But problems of pro-viding of safety at imposition of arrest (the article 261 KPK of Ukraine) review and withdrawal of correspondence (the article 262 KPK of Ukraine), that this article is dedicated to, in scientific sources not examined.The scientific novelty of the article is actualization of the problems related to providing of safety during realiza-tion of covert investigative (search) activities using special technical tools on the postal communication network and development of the only approach to creation of mechanism of cooperation between law enforcement authorities and Public Company «UKRPOSHTA», that provide the complex using of organizational measures and special technical tools for realization of covert investigative (search) activities using special technical tools on the postal communication network to identify attachments in postal items that may threaten human life and health, including explosive devices or hazardous substances. Besides, the article contain unmasking signs of postal items indicated explosive devices or hazardous substances forbidden current legislation for forwarding on the postal communication network.Thus, normative legal documents and technical support of unspoken covert investigative (search) activities carried out using special technical tools do not fully meet the modern operational tasks set by the state law enforcement agencies. Therefore, the issue of further development and coordination of legislative and departmental acts, improve-ment and introduction of the latest technologies, modern equipment in search and investigation activities arose.
Withdrawal of biological samples for forensic study: regulatory rulemaking and practical law enforcement matters of argue
Authors: Leiba O.A.
Published: October 2021

The article is dedicated to the exploration of a legal nature of such a procedural action as a withdrawal of biolog-ical samples for forensic study, effectiveness of its regulatory rulemaking and practical law enforcement. With in the frame work of the study the attention focuses on the fact that procedure of selecting of biological samples for expert study is one of the examples of the procedural actions, which simultaneously affectsa wide range of human rights. Therefore it is no coincidence that a number of procedural preventive actions are provided legisla-tively, ignoring which should have inadmissibility of evidences gained in such a way as a result.Undertaking the analysis of regulatory rulemaking of withdrawal of biological samples for forensic study the author underlines its unreasonable compactness, which in general leads to negative subsequence, in particular to misinterpretations arising in law enforcement activity. Inter alia it is mentioned that “biological samples” concept is not regulatory entrenched in terms of legislation which is in its turn responsible for terminological inexactitude of the highlighted concept in law enforcement practice. For this purpose one of the suggestions brought forward by the author is regulatory establishing of the concept “biological samples”.In the article special attention is dedicated to the research of a non-consensual biological samples withdrawal in the context of the implementation of one of the key principles of criminal proceeding – freedom from self-incrimination. Emphasis is placed on the fact that the non-consensual biological samples withdrawal for forensic study is followed by a significant degree of interference in the sphere of human rights and freedoms in particular. Therewith in number of cases it will be impossible to clarify certain circumstances in criminal proceeding without obtaining the relevant materials. According to the court practice, including the European Court of Human Rights practice (hereafter – ECtHR), it is concluded that in the scope of observance of the freedom from self-incrimination it is admissible to withdraw such a material from a person, existence of which does not depend on his/her will.The article substantiates the conclusions and formulates the suggestions aimed at improving of regulatory rulemaking of withdrawal of biological samples for forensic study and practice of implementation of the mentioned procedural action.
Policy of international organizations on information security
Authors: Kononenko V.P. , Novikova L. V. , Kopytska P.O.
Published: October 2021

The article is devoted to the study of the problem of international information security. It is part of overall international security. International information security is a state of international relations that excludes a violation of global stability and threats to the security of states in the information space.Information threats are a new challenge to international peace and security. Therefore, for effective counteraction, it is necessary to adapt to modern realities. Since international organizations are created to unite the efforts of states to achieve certain goals, they (organizations) must also adapt to changes. They must transform their policy in the field of international security and, in particular, in the field of information security. Accordingly, the subject of this research is the transformation of the policy of international organizations in the field of information security.International organizations are adapting to new threats in two directions:1) transformation of the structure of the international organization itself;2) transformation of the security policy of international organizations.The transformation of the security policy of international organizations can be divided into internal and external.The internal transformation of the security policy of international organizations presupposes a reorientation (or additions) of their goals of activity. If earlier, speaking of global security, they meant only military-political security, today it is also food security, climate security, space, energy and information security.External transformation of the security policy of international organizations presupposes close cooperation with regional organizations, departments and governments of states (according to the level of communication) in the field of information security.Defending its information interests, each state must take care of information security. The strengthening of the Ukrainian statehood also requires the same. A balanced state information policy of Ukraine should be formed as an integral part of its national security. And also as a part of socio-economic policy in accordance with the priorities of national interests and threats. From a legal point of view, it is based on the principles of a rule-of-law democratic state and is implemented through the development and implementation of relevant national doctrines, strategies, concepts and programs in accordance with applicable law.

Authors: Novytsky V.V.
Published: October 2021

The purpose of the article is to provide a list and briefly analyze international legal mechanisms, as well as legal sources and acts of the EU aimed at regulating the use of the Internet and electronic communication technologies within the organization; identify areas, status and directions of internal and external harmonization of the described regulatory mechanisms. Scientific novelty of the work is to consider the mechanisms and basic regulations of the European Union in the process of their creation and in terms of their role in the formation of a single digital space of the organization. Specific works of domestic scientists in the relevant field were generalized and supplemented, as well as the basis for further research was established. In the early 2000s, EU lawmakers focused on the develop-ment of basic regulations in the field of telecommunications, digital networks and Internet services. As a result, a number of Directives and decisions have been adopted since 2002; at the same time, the development of regulatory mechanisms that would operate within the digital space of the EU actively lasts since 2009. This new stage in the process of developing harmonized mechanisms for regulating electronic communications services and the Internet culminated in the adoption in 2009 of a number of legal documents, including Regulation (EU) 1211/2009, which established the Body of European Regulators for Electronic Communications (hereinafter – BEREC), which took over the role of the national regulatory authority (hereinafter – NRA). In 2018, as part of the creation of a single digital space in the EU, an updated BEREC Regulation was adopted, as well as the Electronic Communications Code (hereinafter – the Code).Now the field of electronic communications and the Internet is undergoing numerous stages of development and reform. The research identified the main directions of EU policies, which include measures to harmonize and unify legislation for more effective interaction within both the EU and external partners: cybersecurity, copyright and personal data, and telecommunications services. These areas, since 2013, have been the focus of efforts, given the complexity of regulation and a rapid development of technologies. In the article, the author covers come theoretical and practical aspects of the European Commission’s activities on Internet regulation and describes the creation of the EU single digital space in terms of the process as a whole.Thus, the result of the study was a descriptive analysis of the process of formation of the EU’s legal framework, roles of organizations and institutions and the status of electronic communications and the Internet regulatory mechanisms.
Four Bosons EM Gauge Invariance and EM Flux
Authors: Chauca J. , Doria R. , Soares R.
Published: October 2021

Electromagnetic phenomena is based on electric charge and spin. However, Maxwell equations are just macroscopic. There is a microscopic EM phenomena to be understood. A performance originated from electric charge microscopic behavior. Thus, keeping on mind the two basic EM postulates, which are light invariance and charge conservation, Maxwell is extended to a Four Bosons Electromagnetism. It says that, the macroscopic Maxwell equations does not describe all electromagnetism. The electric charge physics has been studied microscopically through elementary particle physics. A new perception of EM phenomena emerges based on three interconnected charges {+, 0, −} under four intermediated bosons {Aµ, Uµ, V±µ }. From Maxwell photon, EM becomes a systemic cooperation between four fields. This quadruplet originates a new electric charge physics. New features for electric charge conservation, exchange, conduction, interaction are derived. The research is to analyze the Four Bosons Electromagnetism gauge invariance and EM flux. The model is studied under U(1), SO(2)global and U(1)×SO(2)global symmetries. Two approaches are considered. Based on fields strengths and on fields. A gauge invariant quadruplet physics is obtained under free coefficients conditions. A nonlinear EM flux appears. Without requiring electric charge as source nonlinear fields work as own sources for flowing spin-1 and spin-0 waves and particles. It flows through a four potential field quadruplet, granular and collective fields strengths. A self contained EM is constituted providing a nonlinear physicality that precedes physical constants as electric charge and medium parameters. The EM meaning is enlarged and we have to understand on the physical structures generated by this antireductionist nonlinear four bosons microscopic electromagnetism. Determine the corresponding fields blocks which are real and gauge invariants. They are identified as the electromagnetic domains. The Four Bosons EM develops interdependent EM domains. Interlaced physical sectors sharing a common EM energy context. Lagrangian, equations of motion, conservation laws are expressing such domains physics. They correspond to physical sectors where each one contains its own EM energy.

Published: October 2021

In recent years, herbal medicines have become increasingly popular in the pharmacotherapy of many diseases. One of the medicinal plants widely distributed in the wild on the territory of Ukraine is common tansy (Tanacetum vulgare L.) of the Asteraceae family; it is a promising raw material for the development of new medicines. In this regard,it is relevant to study and standardize a dense extract of common tansy flowers (DECTF) to predict the possible pharmacological action and the feasibility of further use in the production of solid dosage forms.
Aim. To study the qualitative and quantitative content of the amount of flavonoids and the amount of hydroxycinnamic acids in a dense extract of common tansy flowers.
Materials and methods. The study object was DECTF. The qualitative composition of phenolic compounds in the extract was determined by TLC. The quantitative determination of the amount of flavonoids calculated with reference to luteolin was performed by the spectrophotometric method.
Results and discussion. The identification of DECTF was performed by TLC. It allowed us to identify 3 dominant compounds of phenolic nature – luteolin, luteolin-7-glycoside and chlorogenic acid. The quantitative content of phenolic substances in DECTF was studied by spectrophotometry; it was found that the amount of flavonoids (calculated with reference to luteolin) was 3.69 ± 0.01 %; the amount of hydroxycinnamic acids (calculated with reference to chlorogenic acid) was 16.88 ± 0.02 %.
Conclusions. A significant content of flavonoids and hydroxycinnamic acids in DECTF indicates the prospects for further research and development of new drugs with the anti-inflammatory, antimicrobial and choleretic action based on it.

Authors: Kutova O. V. , Ruban О. А. , Alkhalaf Malek W. A.
Published: October 2021

Aim. To determine the algorithm of the optimal amount of excipients in the composition of tablets based on common ginger.
Materials and methods. The study object was the regression equations determining the quantitative effect of excipients in the composition of the dosage form on the target pharmacopeial characteristics. The mathematical processing of these equations was carried out using the Mathcad 15 computer program according to the algorithm proposed.
Results and discussion. It has been proposed to use the approximation function to determine the level of optimization. The approximation function is the sum of the squares of deviations of the objective functions from their optimal values. It has been proven that identification of mathematical models in pharmaceutical studies with three dependent factors, which total value is determined by the quantitative composition of a dosage form and is fixed at a certain level, is difficult to perform due to the complicated interpretation of multiple regression parameters as characteristics of factors in an isolated form through their correlation. The region for the optimal solution has been proposed with respect to the values of factors and effective indicators of a multiple regression model. The methodological approach to determining the optimal content of excipients in the composition of the given dosage form has been proposed.
Conclusions. The optimal content of excipients – neusilin and colidone – has been determined while developing the composition of tablets based on common ginger with the necessary pharmacological and technological indicators that meet the requirements of the State Pharmacopoeia of Ukraine. The approach to the formation of the region offeasibility in two-way studies has been considered. Using the theory of multi-vector optimization a criterion has been developed; it allows determining the optimal feasible solution in the region under conditions of restrictions both by factors and target indicators.

Authors: Tomchuk – Ponomarenko Nataliia Vladimirovna
Published: October 2021

Urgency of the research. The solution of problem of increase in war on corruption, at least in relation to limitation of its extent, is still one of the most serious and complicated problems on the path of the establishment of Ukraine as an independent democratic, law-governed and social state. Global political and social and economical changes occurred in Ukraine upon declaration of independence became not only the fundamental of progressive social processes but also of many negative phenomena the most dangerous of which the corruption is.
Actual scientific researches and issues analysis. The increasing interest to scientific comprehensive understanding of corruption was observed gradually within last years; the number of scientific published works rose steeply. The enhanced study of this phenomenon is reflected in papers of Z. Varnalii, M. Honcharenko, O. Dulskyi, A. Zakaliuk,
V. Zelenetskyi, O. Kalman, V. Klymenko, M. Korniienko, V. Mandybura, I. Mazur, M. Melnyk.
Uninvestigated parts of general matters defining. Due to complexity of understanding of the phenomenon of corruption the field of its scientific research substantially lies within the frameworks of absolutely legal conception. Knowledge about this phenomenon are distributed in many adjacent fields of sciences – political science, social science, philosophy, psychology, political economics, ethics, theory of management, history of political and legal thought and others. However they are rather unsystematized; the substantial features of corruption as the specific institute are not examined thoroughly that has an absolute antisocial orientation; objects and subjects that form and embody it are not clearly defined.
The research objective. The purpose of the paper is to research main substantial features of corruption revealing its "qualitative differences" and "specific particulars"; definition of “unethical and ethical” regulations upon which the institute of corruptive relations is bases; outlining of objects and subjects that form and embody them; justification of measures that can cope with corruption and economical crime efficiently.
The statement of basic materials. The paper covers the main substantial features of corruption that identify its “qualitative differences” and “specific particulars” and justifies the most efficient ways and organizational and financial means of creation of conditions for overcoming of criminal crime in Ukraine.
Conclusions. Summarizing all above-mentioned information it is to be noted that the corruption nowadays evolved into such social and political phenomenon that has to be perceived not just as one of inevitable negative development related to civilization but as an evil that brings about the real threat to national security of mankind. It became the global challenge for the whole human civilization.

Актуальність теми дослідження. Представляє інтерес дослідження відповідності заявлених цілей щодо розбудови інноваційної моделі економіки змісту конкретної політики їх реалізації.
Постановка проблеми. Показники розвитку інноваційно-інвестиційної діяльності в економіці свідчать про відсутність адекватних законодавчих актів в частині фінансової підтримки інноваційної діяльності та обмеженість фінансових можливостей реального сектору економіки.
Аналіз останніх досліджень і публікацій. Значний науковий і практичний внесок в дослідження механізмів фінансового забезпечення інноваційно-інвестиційної діяльності становлять праці провідних науковців В. Гейця, В. Александрової, Л. Федулової, А. Даниленко, С. Онишко та ін.
Виділення недосліджених частин загальної проблеми. Високий динамізм розвитку, загострення економічних, політичних протиріч вимагає вдосконалення фінансової бази інноваційної діяльності підприємств.
Постановка завдання. Метою статті є дослідження тенденцій зміни структури капіталу в галузях реального сектору економіки та оцінка їх впливу на інноваційно-інвестиційну активність підприємств.
Виклад основного матеріалу. Дослідженням виявлені негативні тенденції зміни структури капіталу підприємств базових галузей економіки. Зменшується частка власного капіталу, більше половини джерел фінансування припадає на поточні зобов’язання. Скоротились кредитні програми для бізнесу, що зумовлено високими процентними ставками та низьким рівнем рентабельності підприємств. Негативний вплив на ці процеси здійснила монетарна політика НБУ: трикратне знецінення національної валюти, висока інфляція та облікова ставка поглибили кризу і обмежили доступ підприємств до кредитних ресурсів.
Висновки. Стратегія управління економікою країни орієнтована на екстенсивний розвиток. Якщо вона буде консервуватись і на майбутнє, то економіка України залишиться не конкурентноздатною, не спроможною вирішити проблеми бідності значної частини населення, втратить свій науково-технічний, інтелектуальний потенціал. Обгрунтовані напрямки зміцнення фінансової бази інноваційної діяльності бізнесових структур та підвищення їх інвестиційної привабливості.
Modelos psicolinguísticos de reconhecimento de sons de fala
Authors: Silveira Amanda Post da
Published: October 2021

Este trabalho traz uma contribuição crítica sobre os modelos de reconhecimento de sons de fala, mais especificamente sobre o papel (quando existe em tais modelos) do acento de palavra tanto no sistema cognitivo tanto de monolíngues quanto de bilíngues no acesso lexical em fala contínua. Argumentaremos que em muitos dos modelos clássicos de reconhecimento de palavra não é previsto o papel do acento, coisa que modelos mais recentes têm tentado dar conta. Porém, evidenciamos que não há um modelo de representação, processamento e reconhecimento de fala bilingue que explique o papel do acento de palavra. Mostraremos possíveis caminhos de como essa implementação pode ser feita, sem, contudo, exaurir as possibilidades. Esse trabalho pretende também trazer uma contribuição para a psicolinguística do bilinguismo, uma vez que traz uma revisão crítica de modelos de linha conexionista, tentando promover um debate entre partes que trabalhem nessa linha. Pretendemos apresentar mais discussões sobre a relação acento lexical e acesso lexical em futuros trabalhos que estão sendo publicados em sequência, da qual este trabalho faz parte.

Purpose. Fire extinguishing efficiency of flooding with temperature-activated water (TAW) sprays depends on the constituent droplets size and their distribution density. This work is aimed at determining effective characteristics of TAW polydisperse droplet phase for extinguishing fires in confined spaces. The research objectives are: 1) theoretical research of TAW extinguishing capacity dependence on its discharge parameters; 2) developing a generalized model of droplet motion in highly heated fluxes based on the physical process of TAW droplets evaporation in hightemperature environment; 3) modeling the evaporation process of TAW polydisperse droplet phase using the MathLab hardwaresoftware system. Methods. Chemical thermodynamics theory has been used to study evaporation and motion processes of TAW droplet phase. Similarity theory and algorithms theory have been used to simulate the evaporation process of TAW polydisperse droplet phase. Findings. The research has made it possible to establish that the most effective fire extinguishing characteristics are exhibited by temperature-activated water sprays, having droplets with a diameter of less than 5 µm distribution density of more than 60 %. In addition, it has been found that evaporation process of TAW sprays containing a greater number of first mode droplets has a parabolic-asymptotic character. Research application field. The compiled model can be applied to describe the evaporation process of water polydisperse media in highly heated fluxes, as well as to increase flooding efficiency with TAW sprays. Conclusions. Flooding process by means of TAW simulation makes it possible to determine the most effective fire extinguishing characteristics of its discharge for flooding. In further studies, it is advisable to simulate TAW sprays with inhibiting water-soluble salts evaporation process.

Purpose. Fire development model application field to assess fire resistance of steel basic structures, taking into account the terms of use of buildings and structures was determined. Methods. The regulatory sources were analyzed by the authors; calculation of steel structures heating with and without fire protection were carried out under the conditions of a standard temperature regime of a fire and a regime of hydrocarbons combustion using the Ansys software package; the calculations were compared with experimental data. Findings. The conducted research to assess steel structures fire resistance under the conditions of a standard temperature fire regime and hydrocarbons combustion regime demonstrated the possibility of calculating their heating using the Ansys software package. It has been established that the fire resistance limit for the loss of steel structures bearing capacity without fire protection at a standard temperature regime is 2 times higher than at a hydrocarbon temperature regime, and with fire protection made of cement-sand plaster or Newspray coating - 1.2-1.3 times. Research application field. The calculated values of the limits of steel basic structures fire resistance with fire protection made of cement-sand plaster or Newspray coating for a standard fire temperature regime can be used in the design and reconstruction of residential, public and office buildings. When designing buildings and structures of oil and gas, petrochemical enterprises, offshore fixed platforms for oil and gas production, the calculations outcomes for steel structures fire resistance under conditions of a hydrocarbon temperature regime should be used. Conclusions. The possibility of calculating the actual limit of fire resistance of unprotected steel building structures and structures with fire protection under the conditions of a standard fire temperature regime and hydrocarbons combustion regime with using the Ansys software package was determined. The resulting nomograms of steel structures fire resistance with fire protection made of cement-sand plaster and the Newspray coating may be used to design passive fire protection systems at construction sites, taking into account the standardized fire temperature regimes, depending on the terms of structures use.

Purpose. The article describes constructive and technical solutions for preventing and reducing the consequences of household gas explosions in residential multi-apartment buildings equipped with a fixed gas supply system. Methods. The statistical data on household gas explosions in residential gasified multi-apartment buildings on the territory of Russia have been analyzed. The comparison of existing technical solutions and measures aimed at preventing an emergency explosion and reducing the explosion consequences (gas leak sensor, ventilation system, safety structures of the hinged and swing type) has been carried out. Findings. The data showing the timeliness of this problem due to the significant number of fatalities and large property damage have been obtained. In particular, during the period from 2017 to 2020, 37 explosions of household gas occurred in residential multi-apartment buildings, causing death of 61 people. Despite many positive aspects, the methods being currently used do not provide an adequate level of explosion safety, and therefore the authors see it appropriate to introduce measures aimed at reducing consequences in the event of gas explosion. One of such solutions is the use of a window opening as a safety structure. The main disadvantage, which does not allow us to consider blind glazing as a safety design, is the restriction on the glass thickness (4 mm). In addition, the drawback of using the given construction is low thermal insulation ability and high risk of causing damage to people near the building by glass fragments in the event of an explosion. This disadvantage of modern double-glazed windows can be eliminated by modifying the window frames with the help of special parts or weakened fasteners, which, if excessive pressure occurs, would ensure timely opening of the structure. An example includes safety structures on hinges, which have the ability to rotate these structures when exposed to excessive pressure. Another type of a safety construction is a swing safety design. At a given excess pressure on the working sash, the locking devices, which release the frame rotary sash, are triggered.Research application field. The results of the study can be used in the working out new technical solutions designed to prevent an emergency explosion and reduce the consequences of a potential explosion. Conclusions. The conducted research leads to the conclusion that further work is necessary to study the parameters of internal emergency explosions of household gas in residential buildings under various accident scenarios in order to develop optimal solutions to minimize the consequences of an explosion.

Purpose. The article analyzes crisis management subject area on receiving a signal about an emergency in crisis management center (CMC). Statistical data on emergencies for the period 2016-2020 have been provided. A review and analysis of Russian and foreign research works in the field of development and application of information technology during disaster response stage have been carried out. Based on the results of the analysis, the task to formalize a disaster response stage by crisis management, develop the model of emergency classification using machine learning methods has been set. The functional model of the subject area “Crisis Management Center performance on receiving a signal about an emergency” has been presented. The main stages of ontology creation of the considered subject area have been formed, instances of the ontological model have been decomposed and identified, a set of properties-relations of the components has been defined, a flow chart of the model has been presented. Methods. To formalize the disaster response process by crisis management the authors of the article have used the method of functional simulation.In order to compile the semantics of the subject area three main methods of ontology building have been defined: frame method, production rule method, semantic networks. Findings. To formalize the process of making management decisions by crisis managers the functional model according to the IDEF0 standard has been developed. The composition order of ontological model “Crisis Management Center performance on receiving a signal about an emergency” has been determined, the main components and properties- relations have been identified. Research application field. The obtained results will make it possible to formalize the considered process of making decisions by crisis managers, identify patterns and define areas requiring development in disaster response management support system. Conclusions. In the course of further work, it is planned to compile an emergency database, develop the emergency classification model in order to improve emergency management when responding to man-made disasters.

We report a case of a 59 years old male patient who reported chronic effort chest pain. Transthoracic Doppler echocardiography (TTDE) presented normal left ventricular systolic function with retrograde coronary artery blood flow in the distal and middle part of the left anterior descending artery (LAD). On the basis of findings of TTDE, we suspected chronic total occlusion (CTO) of the LAD, which was confirmed by invasive coronary angiography. The LAD CTO was successfully opened by a catheter-based intervention. After the percutaneous coronary intervention, the patient became completely free of symptoms. The repeated TTDE study showed the cessation of reverse coronary blood flow and the return of the physiological antegrade flow in the LAD.

In this article, we present the case of an 81-year-old male patient having left ventricular systolic dysfunction partly due to chronic myocardial ischaemia who was diagnosed with true severe aortic valve stenosis. After treatment of coronary artery stenosis, transcatheter aortic valve implantation (TAVI) was indicated, but the course of the disease was rapidly progressive, left ventricular systolic dysfunction became very severe by the time of the planned intervention, and acute right ventricular failure developed as a consequence as well. No haemodynamic instability occurred therefore the intervention could be postponed and could be performed routinely without any significant risks after successful inotropic therapy. Based on the one-year follow-up, TAVI was successful, left and right ventricular systolic function almost completely normalized.
Des expressions et des sentiments sur des pavements dionysiaques de l’Algérie romaine

The figurative ancient mosaics often represent “living” paintings which depict mythological, historical or real personages who manage to express various feelings thanks to the ingenuity of the mosaic craftsmen.

Indeed, the art of ancient mosaic has not ceased to evolve since the Hellenistic period in the direction of the translation of the emotions and feelings that give life to the myths and legends represented.

The mosaics which decorated the ceremonial and reception rooms in luxurious domus did not only play an ornamental role, they entertained the guests, stimulated all their senses and provoked the exchange of conversations around the table. The Dionysian mosaics were particularly intended for this function because Dionysus is the god of the banquet!

By admiring some of the many pavements of the Dionysian legend of Roman Algeria, one can detect the rendering of emotions and soak up an unreal and almost real atmosphere at the same time! ...

This article is an invitation to discover a whole range of sometimes contradictory feelings that appear on mosaics; we will thus be able to see how the African mosaicists from the end of the 2nd to the 5th century A.D. used various methods to make their personages more expressive and alive.
