Published: January 2020

Noninvasive techniques, such as Magnetic Resonance Imaging (MRI) are becoming more used in the study of bone regeneration outcomes, in both animal models and human patients. Many studies have shown the potential of tissue engineering therapies to promote healing of skeletal injuries, but further research is needed to optimize these treatment options. This investigation is a continuation of other previous published studies, in which critical-sized bone defects created in the parietal bones of Wistar rats were filled with either bioglass or a biologic collagen scaffold seeded both with adipose-derived mesenchymal stem cells. The present study aims to present the applications of MRI in the assessment of the bone regeneration process in these previously created defects, at specific time intervals. MRI techniques are based on the differences between the spin-latice T1 and spin-spin T2 relaxation times of examined specimens or areas, compared to normal tissues. We measured the relaxation times specific to calvarial specimens with a Brukner Minispec. The results showed that the most favorable results were observed when a collagen scaffold seeded with stem cells was used. MRI enabled the detection of hard and even soft tissue changes, these findings suggesting that MRI could be an effective imaging modality for assessing changes in bone morphology and pathobiology. Furthermore, it can be used as an alternative to Computed Tomography in examining the role of various biomaterials used in bone healing, especially when ionizing radiation is contraindicated.

In this study, the effect of polymers on the mechanical properties of ketoprofen extended drug release systems were studied. Many polymers are added in formulation of compressed tablets in order to improve the physicochemical characteristics of the drug release system. The samples were made in the form of cylindrical tablet about 9 mm in diameter, containing different mixtures of drug substances and excipients acording to seven formulations. Cylindrical tablets containing mixtures of ketoprofen and various types of polymers are made by direct compression method. Among the binders used were a series of different polymers like Kollidon va 64, hydroxypropyl methyl cellulose and sodium carboxyl methyl cellulose. Mechanical parameters such as hardness, mechanical strenght, friability and roughness were studied in order to determine how they are influenced by polymeric binders.

A facile and inexpensive approach was established to prepare spherical molecularly imprinted polymers with hypericin (H-MIPs) via the wet-phase inversion method. The H-MIPs were characterized by infrared spectroscopy and thermogravimetric analysis. High-performance liquid chromatography combined with UV-Visible spectroscopy were used to assess the efficiency of the extraction procedure and, furthermore, to investigate the recognition properties of the H-MIPs. Obtaining an imprinting factor of 3.38 for hypericin strongly indicated a successful formation of molecularly imprinted cavities onto the H-MIPs. A fair selectivity towards hypericin was tested in comparison to the interfering molecule pseudohypericin.

The enterprise has an intricate and elaborate system of relationships between the departments, functioning closely as a cell within an organism, with its defined role within the market. In the complex context of actual economic system, resources are limited and enterprises seek for efficiency in order to reduce costs. In this paper we present the development of a solution for the optimization of an agricultural enterprise related to the plastic-based materials usage in the agricultural processes. In this matter, the experimental part consists in the creation of a model of a plastic management system using methodologies from the literature (e. g., System Dynamics or SD etc.) and its simulation with specific tools used traditionally. Besides the experimental part, we will make a short analysis regarding the structural and economic issues regarding plastics used in agriculture and some considerations regarding the bioplastic material that can be obtained from different types of agricultural waste.

Carbapenem antibiotics resistance is a medical threat in antibacterial therapy as the pathogen resistant strains easily evolve a multi-drug resistance action to other incurable agents. The protective transport of current antibiotic molecules using nano-carriers initiates a huge approach in the antibacterial therapy, allowing the nanohybrids to defeat all these health threat pathogen agents. Chitosan is a linear cationic polysaccharide being often used in medical area as a biocompatible encapsulating agent in antibiotic delivery nanosystems. This work refers to encapsulation of imipenem into biodegradable chitosan nanoparticles in order to destroy antibiotic-resistant bacteria and limit the microbial adhesion and multiplication. Nanoparticles were prepared by ion gelation method using tripolyphosphate as cross linking agent. The obtained hybrid nanocapsules were then characterized and evaluated as a potential nano-device to beat antimicrobial resistance.

Published: January 2020

The CAD/CAM technology has been successfully integrated in clinical and laboratory aspects of dental medicine. The present in vitro study focuses on the biochemical interactions between saliva and three types of polymeric resins for occlusal splints. Dental material samples were produced from 3D printed, milled and self-cured resins and were incubated with saliva samples from 20 healthy volunteers. The results showed that the 3D printed and milled polymeric resins did not produce any significant changes in oxidative stress parameters (uric acid, TAC, GGT, OXSR-1) or inflammatory markers (IL-2, IL-6). On the other hand, the self-cured acrylic resin produced a significant decrease in the salivary TAC and uric acid, the most important antioxidants in saliva, affecting the capacity of saliva to protect the oral environment against oxidative stress.

The high global production of electric and electronic equipment increases in the same manner the amount of the waste that needs to be recycled. Special attention is given to the plastics recycling from the waste in addition to the metals recovery that brings economic advantages. Considering that the plastic amount contains about 80% polystyrene polymers, the paper presents a recycling study of this fraction as reinforcing agent for a styrene-butadiene block copolymer. In order to reduce the melt viscosity, some of the composites were extended with paraffin-naphthenic �heavy white oil�. The blends were characterized by mechanical testing, thermal and dynamo-mechanical analysis. Based on the resulted properties, it can be concluded that the extended and reinforced composites can be used as material for shoe soles.

Materials used in additive techniques are initially in a plastic state to be inserted into different cavities or easily molded (a blunt, for example), after which they pass into a rigid phase. This process is carried out by various methods depending on the material nature. The process can be purely physical (solidifying the alloy melt, the termoplasticized macromolecular compounds), modification and rearrangement of the internal structure (sintering of ceramic masses, crystallization of glasses, amalgam intake), a process of evaporation of some components (lacquers, plasticizing polymers) or a chemical process. This latter process can be an acid-base reaction between two inorganic substances (PCZ, CIS cements), a chelating reaction (ZOE cements) between a phenolic range (organic compound, usually eugenol or orthoethoxybenzoic acid) and an inorganic powder (ZnO) or a reaction in which a macromolecular compound is formed. After the type of the reaction, the macromolecules are classified into polymers (the formation reaction is called polymerization, the compounds of which are obtained by monomers, the main chain is formed by the carbon atom only), polycondensates (the formation reaction is called polycondensation, the chain also formed from heteroatom-ON, depending on the type of material) or substances that are obtained by polyaddition ( a repeated addition, the mechanism being different from the polymerization. Our study was conducted in the Dental Clinic and comprises a total of 17 patients. The group was represented by patients aged 50-85 years. Clinical observations have been made on cases of fracture of acrylic bases, with the analysis and assessment of some clinical aspects with increased risk of fracture (jaw / mandible, median / paramedian fracture line, etc.), which increase the risk to and fracture when associated. Clinical observations have shown the presence of the risk of fracture in acrylic prostheses, with the need first of all for the proper design and realization of mobile prostheses, but also for the use of inserts.

Published: January 2020

Orthodontic appliances usually require the joining of different stainless-steel parts in order to achieve adequate control over tooth movement during the active treatment. The aim of this study was to assess the tensile and shear breaking force of the joints between forty orthodontic bands and forty attachments (buccal tubes), joined by laser and TIG welding, without filler material. For the laser welding technique, we used an XXS Laser (OROTIG) welding unit and for the TIG welding technique, a PUK D2 (LAMPERT) welding unit. The tensile and shear breaking force of the welded joints was determined using the Z010 Zwick/Roell testing machine. The independent-samples t-test showed statistically significant differences between the laser and TIG groups for both the tensile and the shear breaking force tests, the laser welded samples having better mechanical strength than the TIG welded samples. For practical use, under normal loading forces, both techniques are suitable for this particular application in orthodontics. In patients with parafunctional habits, that could develop higher bite forces, the failure of the welded joints might occur if the welding surface is not increased, especially for the TIG welding technique.

AREAS OF IMPROVEMENT OF LEGAL REGULATION OF PERSONNEL SERVICE PROVISION
Authors: Andryeyev A.
Published: January 2020

It is stated that the current legal regulation of the personnel support of the civil service of Ukraine does not fully satisfy the needs of the society for the purposes of ensuring the fulfillment of the tasks set, and therefore the issues related to the improvement of the existing mechanisms are still not relevant, since the proper functioning of the state institutions is impossible without a skilled and powerful state apparatus.

The list of problems of legal regulation of the civil service personnel is determined. Suggestions are made to address these issues. It is established that one of the problems of legal regulation of the personnel support of the civil service of Ukraine under the national legislation is the imperfection of the current legislation in this field, which creates "hidden opportunities for positions". Attention was drawn to the need to address corruption issues, in particular, the strengthening of control by staffing services was proposed. For example, when recruiting a candidate for a civil servant position, the HR should, along with checking education data, work experience, etc., pay attention to identifying moral and ethical qualities and the absence of allegations of corruption in the past.

The article analyzes the aspects of optimization of legal regulation of public service personnel. It is proposed to optimize the legal regulation of the staffing of the civil service of Ukraine in several stages in order to increase the level of professional competence of civil servants.

Some researchers have expressed their views on this issue, of which the proposal to focus attention on attracting young creative personnel to the civil service is particularly interesting. In this case, it is advisable to amend Article 19 of the Law of Ukraine "On Civil Service" of 10.12.2015 No. 889-VIII with the establishment of the maximum age of admission to the position of civil service, which in practice can really contribute to the formation of a qualitatively new composition of civil servants. You can set an approximate age of 30 years.

Among the areas of optimization of the legal regulation of the personnel support of the civil service of Ukraine, at the stage of raising the level of professional competence of civil servants, the extension of the personal responsibility of civil servants is highlighted. The main problems for today are that the current Law of Ukraine “On Civil Service” of December 10, 2015 No. 889-VIII provides only two types of liability of civil servants - disciplinary and material. In the Criminal Code of Ukraine and the Code of Ukraine on Administrative Offenses, firstly, the legislator does not use the term "civil servant", and secondly, there are no sections directly related to the offenses and crimes of public servants in the structure of these normative legal acts. the rules may be contained in different sections of the codes.
CONTRACT AS THE REASON FOR THE CURRENT LABOR LEGISLATION OF POLICE IN UKRAINE
Authors: Veretin V.
Published: January 2020

The article is devoted to the study of the contract on service in the police as the basis for the emergence of labor relations of police officers. The article examines the norms of national legislation providing for the use of a contract as a basis for the emergence of labor relations, as well as scientific approaches to understanding the nature and characteristics of a contract. The definition of the “contract on service in the police” and the proposals for the improvement of national legislation in the field of service in the police are given.

It is substantiated that the Labor Code of Ukraine stipulates in fact two grounds for the emergence of an employment relationship: an employment contract and a contract. Along with this it is proposed to highlight other reasons, namely the act of appointment; the act of election to office; the decision of the competition commission; a court decision on the conclusion of an employment contract; referral to work by a body authorized by the law at the expense of the established quota.

It is stated that the scope of contracts is limited by the laws of Ukraine, that is, contracts can be concluded by employers only with those categories of employees that are clearly defined by law. Non-compliance with this rule is a ground for recognition in accordance with Art. 9 of the Labor Code invalid contractual working conditions, which worsen the position of the employee in comparison with the legislation of Ukraine. The thesis that the Labor Code of Ukraine primarily calls the contract a special form of employment contract, however, has been raised in the legal literature regarding this definition.

The author makes arguments about the expediency of making changes to Art. 63 of the Law of Ukraine "On the National Police"
GENESIS OF LEGAL REGULATION OF WOMEN'S LABOR IN UKRAINIAN LANDS

Published: January 2020

The article analyzes the prerequisites for the birth and development of legal regulation of women's labor in Ukrainian lands. The genesis of the genesis of legal regulation of women's labor in the territory of present Ukraine has been determined. The content and meaning of each stage are outlined. Their features are outlined.

The analysis of the basic normative legal acts is carried out and the following features of the legal regulation of women's work in the period from 1918 to 1953 are highlighted: imperative - this feature is revealed through the use of the imperative method for the legal regulation of women's labor; centrality - this feature most clearly manifested itself in labor relations, since even the smallest issues had to be first addressed at the level of line ministries; declarative - means norms that do not contain a specific rule of conduct, but defines the goals, objectives, principles of particular branches of law, legal institutions, subject, form and means of legal regulation; low level of legal technique - different types of legal technique play the role of organizing and constructing legal material, create conditions for rationalization of legal activity, for optimization of the process of legal ordering of public relations.

The following features of legal regulation of women's rights from 1953 to 1991 are also distinguished on the basis of normative legal acts: progressiveness - this feature is manifested through both through the establishment of new legal norms and through restoration; imbalance, because the balance of interests is at the same time the foundation, the inner core, the necessary condition and the path to social consensus; etrocity - the domination of the state in all spheres of society, the "power of power."

Published: January 2020

Young people involved in higher education have created a specific culture, to which, in addition to their studies, social and cultural activities associated with university life are also related (Kozma, 2006). Among these activities, student employment and participation in civic organizations should be highlighted. Voluntary and paid work among higher education students is increasing. These activities have several advantages in terms of future benefits; however, the attracting role of the labour market is one possible reason for dropout. In our current research, we emphasize the role of employment and civil activity in the development of student dropout. Masevičiūtė et al. (2018) found that a quarter of students stopped studying for work-related reasons. In addition, a negative perception of the marketability of the course they are on may lead to the interruption of university studies. In our study, we analysed the extent to which students are willing to interrupt their higher education studies in exchange for voluntary work. In our current research, we examined how often and for what reasons students who dropped out did paid work and volunteering during their studies.

Published: January 2020

This paper presents three applied analysis. Our principal interest is to understand how meso (university level) and macro (national level) contexts interact with micro phenomena such as students’ careers. To achieve this aim, the paper shows a secondary analysis of longitudinal administrative data by means of Sequence Analysis and Event History Models. Furthermore, it shows the results of an additional analysis using a quasi-experimental research on longitudinal data.

The paper examines typical pathways of Italian students, by means of administrative information’s on student enrollment from Sapienza University of Rome. The aim of this paper is triple: 1. describe students’ careers in higher education by building a typology of pathways using Sequence Analysis. 2. Identify how socio-economic and macro level characteristics affect students’ careers by multinomial logistic regression model where clusters are used as dependent variables and focus on the study of the “event” by using Event History analysis. 3. Evaluate the Italian Higher Education reform policies and their main outcomes throughout a quasi-experimental research.

Mainly, the outcomes show the importance of the warming-up period, the individual choice and the exogenous events after enrolment in determining the success/failure of each career. Our outcomes suggest that Italian universities should rethink the mechanisms available to manage failure and guide student choices.

Considerando a importância de políticas públicas voltadas para o atendimento ao escolar em tratamento de saúde, o presente estudo teve como objetivo geral descrever a experiência dos participantes em um curso de formação colaborativa reflexiva, acerca da implantação da política para o atendimento ao escolar em tratamento de saúde por meio das classes hospitalares. A presente pesquisa se constitui de caráter colaborativo com abordagem qualitativa. Participaram da pesquisa 22 participantes. O local da coleta de dados foi uma Diretoria de Ensino, situada em uma cidade do interior do estado de São Paulo, onde ocorreu um curso de formação continuada colaborativa, sendo realizados cinco encontros presenciais e disponibilizados cinco unidades didáticas na plataforma online do Google Classroom. Os resultados demonstraram que os participantes reconhecem a importância de uma política pública em âmbito nacional, objetivando garantir o atendimento ao escolar em tratamento de saúde, considerando que em muitos casos, as políticas de Estado não são cumpridas adequadamente, assim, muitos alunos não desfrutam da escolarização no ambiente hospitalar. Além disso, destaca-se a luta dos professores de classes hospitalares, buscando um maior reconhecimento desse serviço de suma importância para crianças e jovens doentes. Portanto, reforça-se a importância da criação e efetivação de uma política específica sobre o atendimento educacional hospitalar em âmbito nacional, para a garantia do direito à educação para crianças, jovens e adultos em estado de hospitalização, promovendo a conscientização do governo sobre a importância desse serviço.

Psicologia política e a potência transformadora do espaço escolar
Authors: Santana Jean Costa
Published: January 2020

O presente artigo objetiva discutir o espaço escolar através da interdisciplinaridade da psicologia política. Nesse sentido, buscamos contribuir para um espaço escolar que crie processos de emancipação social e se comprometa, cada vez mais, com a realidade social dos alunos e das maiorias populares oprimidas. Da perspectiva interdisciplinar da psicologia política, como referencial teórico e metodologia, tentamos analisar e discutir elementos psicopolíticos que habitam a instituição escolar, e apresentar concepções de uma psicologia politizada e libertadora, conforme a orientação teórica e prática de Martín-Baró. Para essa análise, não autonomizamos a instituição escolar, separando-a da sociedade, mas a situamos como parte de uma totalidade que se organiza mediante o conjunto das relações sociais sob o capitalismo. E a partir da nossa discussão, concluímos que o espaço escolar possui muitas contradições, justamente porque é um espaço formado por elementos políticos, psicológicos, afetivos e sociais, e também pelo seu potencial de propagar esses elementos. E devido essa importância, é um espaço frequentemente disputado pelo governo, por movimentos populares, por formas de agenciamentos conservadores e reacionários, ou por outras maneiras críticas e revolucionárias. Portanto, reconhecemos que o espaço escolar é um espaço de luta; e como espaço ativo e vivo, por causa de homens e mulheres que o compõem, há a imprescindível necessidade desse espaço estar implicado e comprometido com a transformação social, que tanto necessita nossas populações.
TREASURE OF MARTYNIVKA TYPE FROM THE VILLAGE OF PRAVI SOLONTSI IN KHERSON REGION
Authors: Hanoshenko V. V. , Volodarets-Urbanovich Ya. V.
Published: January 2020

Article presents jewelry findings from Pravi Solontsi in the Lower Dnieper. The assemblage belongs to the circle of Dnieper early medieval hoards of first chronological group by O. A. Shcheglova or Martynivka type.

The complex comprises 20 whole and fragmented metal items and 1 glass bead. All jewelry is represented by elements of women’s attire: details of collar (chain with link of «snake head», tubular beads Volodarets-Urbanovich / type 1, trapezoidal pendants ornamented with two / three punches circles in mid and blue bead) and bracelets (Rodinkova / type 5, subtype 3 and 2, Rodinkova / type 2, subtype of ornamented).

The items existed in the Middle Dnieper region and the Dnieper left bank starting from the end of the 6th / turn of the 6th—7th cc. to the middle / third quarter of the 7th c.

We have three explanations for the reasons for the appearance of the Slavic complex of Martynivka type in the Lower Dnieper. The first is connected with the relations between Slavs and nomads. The owner of the Pravi Solontsi complex could be in depending or in marital relations with a representative of the nomadic tribal union. Other variants are a trade or migration from the Middle Dnieper to the Crimea. Their confirmation is the jewelry of the Dnieper origin in the Crimea and the Pre-Caucasus. In addition, a series of things of Crimean origin is known in the Middle Dnieper and Left Bank Dnieper.

Near the town Oleshky (next to the village of Pravi Solontsi), was find а small bronze fibula without ornament — brooch of the Danube circle (Joachim Werner’s class IH). V. Ye. Rodinkova believes that this find belongs to type Pergamon-Tai-zee, subtype undecorated according to I. O. Gavritukhin and is already a local modification. Thus, the treasure from the Right Solonets is already the second Slavic finds of the early Middle Ages from this micro-region.

The article publishes research materials of the Scythian burial intake from the excavations of the mound Orlikova Mogila near the village Bogdanovka, Bobrynetsky district of Kirovograd region (Northern part of the Black Sea Right-Bank Steppe). The grave was built in an earlier mound of the Bronze Age.

The Bronze Age burial was located in the center and completely destroyed by Scythian grave. After the Scythian burial, the embankment was significantly enlarged, and also strengthened by stone krepida.

By the time of the excavation, the mound had a height of more than 3.0 m and a diameter of more than 30 m.

Scythian tomb had dimensions of 4 Ч 3 m and a depth of 2.8 m. From above it was covered with wooden deck and stone laying.

Despite the devastating repeated robberies, the monument contains artifacts that can be interpreted as grave of a heavily armed warrior — man of 30—50 years old with a high social status. The deceased was accompanied by two dependent persons. Fragments of a metal shell made of plates, arrowheads, and fragments of two antique amphorae were found in the grave.

Of great interest are the finds of bronze parts of a horse harness, located among the stones on the embankment. All these objects have traces of intentional damage, which, undoubtedly, is associated with a certain funeral ritual.

Found objects, especially fragments of ancient amphorae, date the Scythian grave at the end of the 5th century BC.

The appearance of such structures in the mounds of the Scythian pores in the northern limits of the steppe Black Sea region, apparently, should be associated with the promotion of Scythian nomads from the more southern regions

The paper publishes the collection of fibulae from Lysukha Hillfort obtained during the field exploration from 2016 to 2018. The research was conducted by the archeological team of the Science Research Centre «Protective Archaeology Service of Ukraine»» headed by Dr. Yu. Boltryk. The monument on Lysukha Mountain is located in Middle Dnieper region. The settlement was discovered in 1970 by Dr. E. V. Maksimov. During 1990—2005 the site was explored by Dr. V. O. Petrashenko. The results of the research allow to attribute the site as multi-layered settlements with finds of Late Scythian, Zarubintsy, Chernyakhiv cultures and early Slavic times of the 5th—7th c. AD.

The collection includes 29 intact and fragmented fibulae. They have been discovered both in mixed layers and objects. Some of them are found by chance. Fibulae belong to seven typological groups according to the classification of A. K. Ambroz. Finds are represented by Early Roman and Late Roman forms. Three chronological groups could be distinguished: second half of the 1st — early 2nd century AD, third quarter of the 3rd — early 4th century AD and the second third of the 4th—early 5th century AD.

The first group consists of three artifacts. Two finds came to Lysukha through the contacts of its population with Northern Pontic cities. These fibulae were found in the Sarmatian assemblages. One fibula is of Southern Baltic origin. Similar fasteners were in use among the population of Post Zarubintsy circle on the Middle Dnieper area.

The fibulae of Late Roman forms are represented by 23 pieces. The fasteners are made mainly of bronze and iron. Fibulae of the «military» type and Cherniakhiv one are prevailed.
PRECIOUS ITEMS FROM THE SHUMEIKO BARROW

The paper deals to the finds from the barrow near the Shumeiko farm in the Sula river basin (now Sumy region of Ukraine) which was excavated by Sergei Mazaraki in 1899. Objects of Scythian culture were found in the mound: weapons, horse bridles, and vessels. Mikhail Rostovtsev mistakenly attributed to these finds the fragment of ancient Greek kylix of the end of the 6th century BC. Modern researchers date the barrow assemblage near the Shumeiko farm to the first half of the 6th century BC (Igor Bruyako, Denis Grechko, Denis Topal, Oleksandr Shelekhan). Sergey Polin attributes it to Early Scythian time.

In the paper three precious items from the barrow are described in detail. This is a sword, the handle of which is plaqued with gold. The ancient craftsman used the granulation technique for decoration. Not only the ancient Greek jewelers used this technique. The masters of Urartu applied it as well. It was used in the decoration of the sword from the Kelermes barrow in the Kuban region, as well as on various adornments. The iron sword has an original shape and belongs to the Shumeiko type (according to Denis Topal, Oleksandr Shelekhan). Such swords were most common in the first half of the 6th century BC. The scabbard was decorated by the gold plate with images of animals and the gold tip. The analysis shows that the images of wild goats and predators are made in the early Scythian animal style. The sheath tip also corresponds to the early Scythian tradition and finds analogies in the Pre-Scythian time. On the contrary, at a later time (the end of the 6th — beginning of the 5th century BC), according to other principles (barrow No 6 near the Oleksandrivka village, Gostra Mogyla near the Tomakovka village) the tips of the scabbard were made. Near the sword the gold plate in the form of a running hare was found. It was made in the Scythian animal style. This plate was probably part of the sheath decor and adorned a side leather ledge that helped to attach the scabbard to the belt. A preliminary conclusion is made about the belonging of precious items from the Shumeiko barrow to the Kelermes horizon of antiquities of the Early Scythian culture.
«ORIENTAL APHRODITE» ON THE OBJECTS FROM TERRITORY OF SCYTHIA (on the origins of iconography)
Authors: Vertiienko H. V.
Published: January 2020

The article analyzes the origins of the iconography of a woman’s face with a hairstyle that has characteristic curls, which have been deployed in different directions, on the objects of Scythian material culture. This feature of iconography is fixed twice. The first case are four silver and gilded pendants from the barrow 34 near the village Sofiyivka, Kherson region (Museum of Historical Treasures of Ukraine — a branch of the National Museum of History of Ukraine, inv. no. 2755/1—4). The second case, is the image on the working part of a bronze stamp from the Kamyanskoe settlement (Archaeology Museum of the Karazin National University of Kharkiv, inv. no. VN 2089). As for the female hairstyle on these images, it is not typical for classical Hellenic art, but finds parallels in the art of the Eastern Mediterranean and Ancient East. This style is similar to the so-called «Hathoric wig» in the art of ancient Egypt (on stelae, sculptures, amulets, painting on coffins, mirrors, musical instruments, etc.), which influenced the iconography of the hairstyles of female deities («Oriental Aphrodite») of the Mediterranean. The image of the goddess in the «Hathoric wig» could permeate to the Northern Pontic Sea Region through the Hellenic craftsmen, as a replica of the image of «Oriental Aphrodite» cult of whom may have existed in the region. At the same time, these images could be a «copy» (imitation) made by the Scythian craftsmen directly from the Egyptian original, most likely from some faience amulet, which usually has similar size and sometimes reproduces the head of Hathor. According to Herodotus, in the Scythian pantheon, the figure of Celestial Aphrodite (Aphrodite Urania) was corresponded by Argimpasa (Herod. IV, 59). Consequently, in such an iconographic form these images could depict this goddess. The image of the «Hathoric wig» on these objects can be considered the most northern examples of this iconographic element.
UKRAINIAN ARCHAEOLOGY: THE STATE AND PROSPECTS (The subjective impression about the objective state)

Ukraine is one of the richest on archaeological sights countries of Eastern Europe. However this riches strike a discordant note with the traditionally small amount of the Ukrainian archaeologists. The lack of «white» academic and university archaeologists is compensated in Ukraine by the increase of quantity of «black archaeologists» that engage in the plunder of archaeological inheritance of country. Strategy of fight against illegal trade of archaeological artefacts it follows fundamentally to reform in Ukraine, limiting to him the hard scopes of law. Above «black archaeologists» it follows to set hard control of public organs with bringing in of professional archaeologists.

A limit amount of specialists on archaeology and primitive history became one of reasons of wide distribution of amateur «conceptions» and wild fantasies about the ancient past of region. They inform a population untruthfully and discredit a country.

The Academy of Sciences played a positive role in development of science, however in our time she does not answer the standards of organization of modern world science and needs deep reformation. Academic organization of science in soviet times had not only the strong parties but also numerous defects. Among them hard administration of science, numerous bureaucracy, lag from front-rank schools of western science through the insufficient financing and protracted artificial isolation from western colleagues, absence of contacts with university young people. The last resulted in the catastrophic aging of academic scientific staff.

Ukrainian science and higher education already long time are in the state of deep crisis, to go out from that they can only by joint efforts, by deep reforms in direction of approaching to the world standards of organization of science and education.
