Published: February 2020

The biological cycle of matter in artificial plantations of forest rehabilitation sites of the Western Donets Basin was studied.

The content and patterns of microelements’ migration in plants, tree waste, litter and soils are determined. Manganese, copper, lead, chromium, nickel and titanium were under investigation.

The dependence between the microelements content in tree waste, litter and soil and their main physicochemical characteristics as well as the correspondence of forest growing conditions to the optimal limits of the elements’ content in soil for plants normal development are characterized.

The factors influencing the trace elements content in the fill-up reclaiming layer are analyzed.

The reasons for the wide variation range of the microelements content in the leaves of experimental trees, and the possibility of using different ground types and plantation patterns are explained. It makes possible to estimate the importance of the biological stage of rehabilitation for the preventing technogenic influence on the environment.
The formation of herbage covers in Scots Pine plantations on recultivated lands of Semenivsko-Golovkivskiy lignite open-cut
Authors: Masiuk O. M. , Lisovets O. I.
Published: February 2020

The studies were conducted in the 20-year-old plantations of Pinus sylvestris L. cultivated on recultivated lands of Semenivsko-Golovkivskiy lignite open-cut. The sample areas are located within five types of edaphic variety of technosol that determines the specificity of forest growth conditions and development of forest plantations on man-made slope of 5-8º. Type 1 is located on a plateau. The edaphotope is represented by sandy loam solid with mechanical impurities of rippled clays (0-85 cm) in the upper layer, and sand one deeper. Type 2 is located on the upper third of the slope. The edaphotope is represented by 0-20 cm of loessial clay loam, 20 cm and deeper there is a medium clay. Type 3 is located on the middle third of the slope. The top layer of 0-10 cm consists of humus; heavy loam is 10 cm and deeper. Type 4 is located on the lower third of the slope. The edaphotope is represented by light and medium clays of different colors; below 130 cm brown coal is found throughout the profile. Type 5 is located in the valley line. Edaphotope is presented by the mixture of heavy clay loams, red-brown and coal clay; below 120 cm throughout the profile there is the formation of brown coal. Humidification conditions are atmospheric.

The research results have shown that the formation of grass stand in the Scots Pine plantations depends on number of factors, such as topography, humidification conditions and availability of nutrients, planting density, lighting conditions, etc. The grass stand, formed in the pine plantations is dominated by perennials (78-93 %). Climate morphs are represented by hemicryptophytes (63-79 %). Among heliomorphs, it is observed fragmented dominance of species, partly demanding to light (scioheliophyte) over light-demanding ones that is connected with the increase of density of planting. Mesotrophic group of plants dominates among trophomorphs. Depending on the edaphic conditions, the role of oligotrophic and megatrophic species is growing. The vast number of species among cenomorphs on all plots are the plants that belong to different groups of stepants and ruderants. Most species are pollinated by insects (69 – 79 %) and are spread by the spreading   diaspore with elastic stalks by shocks (42 – 53 %).

Summarizing the research results, it should be noted that, in addition to the influence of woody vegetation on the lower tiers of biogeocenoses, edaphic conditions are of great importance for their formation, as well as elements of the landscape, both created initially and formed as a result of the gradual fragmentary subsidence of the territory of the dump. These factors regulate the ratio of different groups of biomorphs, climamorphs, trophomorphs, hygromorphs, heliomorphs and cenomorphs in the grass stand. Climatic conditions, influence of surrounding phytocenoses of undisturbed lands set the direction of succession on the way of formation of zonal grassy group.
Cognitive-Behavioral Schemes and Their Repercussion Anxiety Personality Education
Authors: Koleva Nelly
Published: February 2020

This scientific work addresses two important aspects of personality with anxiety disorders - cognitive-behavioral patterns and the ability of the anxious person to deal with them. The specific research objective is focused on clarifying the substantive dimensions of negative automatic thoughts, positive thoughts such as the contraversion of negative thoughts and coping strategies in persons with anxiety disorders (panic disorder and generalized anxiety disorder) and in subjects studied without or with mild anxiety. Identifying relationships between automatic thoughts, anxiety, self-efficacy, and coping strategies. The results obtained are entirely oriented towards consultative practice and training technologies.
Based on theoretical analysis and empirical research, the main goal is to: study the influence and interconnections between negative automatic thoughts, the influence of positive thoughts such as the contraversion of negative thoughts, anxiety, coping assessment - strategies for coping with unwanted thoughts in teens with anxiety disorders and in persons without anxiety or mild anxiety. This would lead to a better understanding of the problematic of cognitive-behavioral schemes and the identification of individual strategies to deal with unwanted negative thoughts and the creation of more appropriate individual and group therapeutic interventions to assist learners.
In support of the accepted hypothesis, there is an association between personal inability and desire for change and the negative self-concept in students. The low self-esteem and powerlessness of teenagers in new conditions has been confirmed. A statistically significant correlation between these factors was found in the subjects with anxiety disorders.
NEUROTIC SYMPTOMATICS RELATED TO PERSONAL CHARACTERISTICS IN YOUTH
Authors: Dimov Milen
Published: February 2020

The present study traces the dynamics of personal characteristics in youth and the manifested neurotic symptoms in the training process. These facts are the reason for the low levels of school results in the context of the existing theoretical statements of the problem and the empirical research conducted among the trained teenagers. We suggest that the indicators of neurotic symptomatology in youth – aggression, anxiety, and neuroticism, are the most demonstrated, compared to the other studied indicators of neurotic symptomatology. Studies have proved that there is a difference in the act of neurotic symptoms when tested in different situations, both in terms of expression and content. At the beginning of the school year, neurotic symptoms, more demonstrated in some aspects of aggressiveness, while at the end of school year, psychotism is more demonstrated. The presented summarized results indicate that at the beginning of the school year, neurotic symptoms are strongly associated with aggression. There is a tendency towards a lower level of social responsiveness, both in the self-assessment of real behavior and in the ideal “I”-image of students in the last year of their studies. The neurotic symptomatology, more demonstrated due to specific conditions in the life of young people and in relation to the characteristics of age.

Comparison of Conventional and Pontic Fixed Partial Dentures Over Implants Using the Finite Element Method: Three-Dimensional Analysis of Cortical and Medullary Bone Stress
Authors: Toniollo Marcelo Bighetti , Sá Mikaelly dos Santos , Silva Fernanda Pereira , Reis Giselle Rodrigues , Macedo Ana Paula , Terada Andrea Sayuri Silveira Dias
Published: February 2020

Rehabilitation with implant prostheses in posterior areas requires the maximum number of possible implants due to the greater masticatory load of the region. However, the necessary minimum requirements are not always present in full. This project analyzed the minimum principal stresses (TMiP, representative of the compressive stress) to the friable structures, specifically the vestibular face of the cortical bone and the vestibular and internal/lingual face of the medullary bone. The experimental groups were as follows: the regular splinted group (GR), with a conventional infrastructure on 3 regular-length Morse taper implants (4 × 11 mm); and the regular pontic group (GP), with a pontic infrastructure on 2 regular-length Morse taper implants (4 × 11 mm). The results showed that the TMiP of the cortical and medullary bones were greater for the GP in regions surrounding the implants (especially in the cervical and apical areas of the same region) but they did not reach bone damage levels, at least under the loads applied in this study. It was concluded that greater stress observed in the GP demonstrates greater fragility with this modality of rehabilitation; this should draw the professional's attention to possible biomechanical implications. Whenever possible, professionals should give preference to use of a greater number of implants in the rehabilitation system, with a focus on preserving the supporting tissue with the generation of less intense stresses.
The Evolution of the Benchmarking Methodology Data Envelopment Analysis - DEA in the Cost Regulation of the Brazilian Electric Power Transmission Sector: a critical look at the renewal of concessions
Authors: Lopes Ana Lúcia Miranda , Mesquita Roberto de Barros , Lambertucci Matheus , Lara José Edson
Published: February 2020

Abstract: In 2012, the Federal Government announced a reduction of around 18% of the electric energy tariff going to the consumer. It was up to the National Electric Energy Agency (ANEEL) to create a model that led to the reduction projected by the authorities. To reach this level, the Ministry of Mines and Energy proposed that the electric power transmission concessions be renewed in advance, according to new rules (MP 579/2012 and Law 12.783/2013). An important part of the new rules was the calculation of efficient operational cost through Data Envelopment Analysis - DEA, a methodology already used by ANEEL in two tariff reviews. The objective of this article was to study the evolution of the efficient operational cost calculation models adopted at these times. This analysis showed that ANEEL still needs to promote improvements in the modeling to better represent the operational reality of the concessionaires and eradicate the need for adjustments that reduce the reliability and transparency of the process.
NURSING PROFESSOR IN HIGHER EDUCATION: TIME, MONEY AND RESISTANCE IN THE MANAGEMENT VISION
Authors: Gatto Júnior José Renato , Fortuna Cinira Magali , Sousa Leandra Andréia de , Santana Fabiana Ribeiro
Published: February 2020

ABSTRACT Objective: to analyze university teaching in nursing from an institutional dialectic approach. Method: a qualitative research based on Institutional Socioclinics. Eighteen nursing professors from four regions of Brazil and from six public institutions of higher education participated. For data production, interviews, observations, documentary analyses, individual and collective restitution and use of the research diary were performed. Data was organized for analysis by transcription/translation, recomposition/rearrangement, and final reconstruction/narration. Data analysis was produced from analyzers, based on Socioclinics, Institutional Analysis current of thought, and on the qualitative mode of analysis by questioning and writing. Results: two main analyzers made the institution ‘teaching in higher education and the nursing professor’ emerge: time-money relation and resistance. Teaching time, increasingly associated with money, in managerialist logic, has formatted the nursing professors as passive subjects in the production of knowledge, induced by the evaluation model of the Coordination for the Improvement of Higher Level Personnel and its link to the progression in the university career. In this model, the nursing professor is driven to devote more to research than to teaching. This interferes with teaching conceptions and practices, which are more influenced by managerialism and less grounded in pedagogical theories. Resistance against this model has not yet encountered coping mechanisms. Conclusion: from the analysis produced with the participants, the choices of the nursing professor are so much more grounded in managerialism and so much less based on pedagogical references, especially those arising from dialectical theories. In this sense, resistance is transformed into a movement of adaptation.

Published: February 2020

Abstract In vitro grown plants may have abnormal structural and physiological features. However, the type of the sealing material used in tissue culture may minimize such abnormalities. This study evaluates the influence of the type of sealing of test tubes on the anatomical and ultrastructural features of leaves of Aechemea bromeliifolia (Rudge) Baker (Bromeliaceae), an ornamental bromeliad native to Brazil, grown in vitro. Three types of sealing were used: rigid polypropylene cap (PC), polyvinyl chloride film (PVC), and PC coupled with a microporous membrane (PM). Seedlings germinated in a greenhouse were also studied for comparison. Plants grown in test tubes sealed with PM were more similar to those from the greenhouse, as far as the pattern of stomatal opening, the presence of starch grains, and the organization of the internal membrane system of the chloroplasts is concerned. Plants cultivated in test tubes sealed with PC had higher stomatal density and the chloroplasts had large areas without thylakoids in the stroma. Plants grown in test tubes sealed with PVC had few or no starch grains. These results suggest that microporous membrane used coupled with PC sealing provided natural ventilation, thus contributing to a better plant development.

Published: February 2020

Abstract Sphaerocarpos muccilloi (Sphaerocarpaceae, Marchantiophyta) was described in 1981, being an endemic species and the only species of the family to Brazil. This species is considered as Critically Endangered (CR) according to “Red List of threatened species of the Rio Grande do Sul state”. Sphaerocarpos muccilloi was recorded in three places only in Rio Grande do Sul: Porto Alegre, São Leopoldo and Ivoti (collected from 1963 to 1977). These sites are highly anthropized and the last records being from more than 40 years. After a revision of herbarium specimens and several field trips we recollected S. muccilloi in the Pampa Biome, in Santana do Livramento municipality, at the Ibirapuitã Environmental Protection Area (APA do Ibaratuitã), Mata and Santa Vitória do Palmar municipalities. Another species (S. texanus), not reported to Brazil, was reported now to Paraná state. These new records provide important information about occurrence and distribution of the family to Brazil. Regarding to S. muccilloi, these new records show that the range of occurrence is wider than previous reported. This new data will help the next revision of the Red List of Threatened Species of Rio Grande do Sul and Brazil and will subsidize conservation strategies.
Myrtaceae from the Atlantic forest subtropical highlands of São Joaquim National Park (Santa Catarina, Brazil)
Authors: Wagner Mariana de Andrade , Fiaschi Pedro
Published: February 2020

Abstract Studies that address the floristic composition of the Atlantic forest show that Myrtaceae is one of the richest families in number of tree species. In Southern Brazil, Myrtaceae is present mainly in forest formations, such as broadleaf rain forests and broadleaf cloud forests, mixed needle and broadleaf forests (Araucaria forests), and seasonal semi-deciduous forests. The objective of this study was to survey the Myrtaceae of the upper highlands of São Joaquim National Park, to contribute with the knowledge of its flora. Eight genera and 16 species of Myrtaceae were found: Acca sellowiana, Blepharocalyx salicifolius, Eugenia handroi, Myrceugenia (8 spp.): M. acutata, M. alpigena, M. euosma, M. miersiana, M. myrcioides, M. oxysepala, M. pilotantha, and M. regnelliana, Myrcia (2 spp.): M. aethusa and M. hartwegiana, Myrrhinium atropurpureum, Psidium salutare, and Siphoneugena reitzii. Descriptions, illustrations, an identification key and commentaries are presented. Other studies about Myrtaceae in highland areas of Southern Brazil present Myrceugenia as the richest genus in species, while other mentioned genera were not registered in SJNP upper highlands. The family’s richness patterns and diversity in a local and regional scale should be better investigated in the Atlantic Forest.

Published: February 2020

Abstract Flood and fire can harm plants but they can have survival strategies, such as the seed bank. We aimed to determine the influence of fire and flood on the richness, abundance and diversity of the seed bank. Sampling was carried out in October/2013, year of prolonged drought, and October/2014, year of a heavy flood, in ten areas along the Paraguay River. The areas were selected in satellite images, five with old burn (2010, three years before sampling) and five with recent burn (2013, three months before sampling). In each area, we marked a 20 m long transect with ten 20 × 20 cm quadrats where we collected 5 cm deep topsoil samples, five with and five without litter. Seed bank richness and abundance were determined by seedling emergence. Old burn areas presented greater abundance than recent burn. The drier year presented greater abundance, richness and diversity than flood year. Removal of litter reduced the richness only in the wetter year. There was no difference in richness in the drier year. The removal of the litter did not affect the abundance and diversity. Interaction between fire and flood did not affect richness, abundance and diversity of the seed bank.

The study objective is to explore the potentialities of ultrasound in the detection of metastasis from papillary thyroid cancer (PTC) to cervical lymph nodes in levels II–IV.Materials and methods. In 97 patients with first diagnosed PTC, surgical removal of the cervical lymph node-bearing fat at levels II–IV was performed. All patients underwent preoperative neck ultrasound. The results were verified by histology.Results. Cervical levels II–IV lymph node metastases were revealed in 82 (84,5 %) cases by sonography and in 86 (88,6 %) cases by histology. Ultrasound showed a sensitivity of 93 %, specificity of 81 %, accuracy of 91 %, positive predictive value of 97 % and negative predictive value of 60 %. Of 1620 removed lymph nodes, 443 (27,3 %) showed metastases confirmed by histology. Sonography revealed 422 (26,0 %) metastatic lymph nodes. Metastasis from intra-thyroid tumors was noted in 94,1 % and from extra-thyroid tumors in 87,5 % of patients. Metastasis from solitary tumors occurred in 86,5 % and from multicentric tumors in 92,1 % of cases. Multiple metastases made up 89,5 % and solitary metastases – 10,5 %.Conclusion. Sonography is a highly informative diagnostic imaging method in detecting metastasis from PTC to levels II–IV cervical lymph nodes and can be used for basic assessment of thyroid abnormalities.

The study objective is to analyze the experience of conformal radiotherapy in combination with cetuximab for cervical lymph node (LN) metastasis in patients with early-stage tongue cancer who had undergone multicomponent surgeries.

Materials and methods. This retrospective study included 48 patients with primary squamous cell carcinoma of the tongue (Т1–2) that were treated in Nizhny Novgorod Regional Clinical Oncology Dispensary between 2012 and 2019. The experimental group comprised 25 patients who underwent hemiglossectomy with simultaneous preventive cervical lymph node dissection. The control group was composed of 23 patients who underwent hemiglossectomy alone due to the presence of concomitant somatic pathology. Before surgery, none of the patients had any signs of metastatic lesions in the cervical LNs according to the results of clinical and instrumental examinations. After surgery, 100 % of patients from the experimental group were found to have N1–2b cervical LN metastases at histological examination. Patients from the control group developed clinical signs of cervical LN metastasis within a year after operation. All patients underwent radiotherapy. The experimental group was divided into two subgroups: patients from subgroup 1 (n = 11) received cetuximab due to disease progression, whereas patients from subgroup 2 (n = 14) received cisplatin. Participants from the control group received no chemotherapy due to their concomitant somatic disorders and because regional metastasis was not confirmed.

Results. In the control group, the time between surgery and patient’s death varied between 8 and 14 months. Patients from subgroups 1 and 2 survived for 12–60 months and 8–48 months respectively. So far, 9 patients from subgroup 1 and 6 patients from subgroup 2 are alive. Among them, 8 participants from subgroup 1 and 4 participants from subgroup 2 have no signs of disease progression. Three patients from subgroup 2 died of cardiovascular diseases (they had no cancer progression within 3 months after the completion of chemotherapy).

Conclusion. Preventive lymph node dissection in patients with stage Т1–2 tongue cancer enables early detection of subclinical N1–2b metastases and ensures timely initiation of therapy. Our experience confirmed safety of cetuximab plus radiotherapy used to improve disease control and increase patient’s survival.

The implementation of robotic surgery, in particular the da Vinci surgical system, is one of the biggest breakthroughs in surgery since the invention of anesthesia, and represents the most significant achievement in minimally invasive surgery of this decade. If the use of the da Vinchi robotic system in pelvic surgery has long been the gold standard, the use of this system in surgery of the base of the skull and sinuses is quite rare and is currently more experimental. Due to the lack of description in the domestic and foreign literature, it seems interesting to us to demonstrate the clinical observation of a patient with an orbital tumor.
Implicit theory of personality as a prerequisite for pedagogical intuitions development
Authors: Garipova Yulia M.
Published: February 2020

The article is devoted to the study of pedagogical intuition, its interconnection with the ideas of man about intellect and personality. Pedagogical intuition is frequently used in teachers' work, but the concept of pedagogical intuition and ways of its development is not clear. At the same time, developed pedagogical intuition, as an ability of a teacher to make quick decisions in their professional activity, allows them to simplify and speed up the process of solving professional issues, which is especially important for modern Russian teachers. Due to the high level of bureaucratization of education and a large teaching load, teachers in Russia are very time-bounded in their work.The article suggests that pedagogical intuition can be developed through the development of other personal characteristics. This study examined the relationship of intuitive abilities on the one hand, and the implicit theories of the personality, its learning objectives - on the other. To confirm this thesis, 50 senior students of the pedagogical university of Naberezhnye Chelny were interviewed. Since the sample was not large, the author of this article does not deny the possible error in the results of the study. However, it should be noted that the sample of the study will be increased several times to confirm the results obtained.As a result of the study, significant results were obtained on two scales of the questionnaire of implicit theories and learning objectives by C. Dweck and the questionnaire of the intuitive style of S. Epstein.

The results of the method of intensification of educational activities of students using web quest technology in practice to increase their motivation to learn a foreign language. The authors present a method of using the modern scenario of the organization of project activities of students on the topic using the resources of the Internet. It includes the use of technical tools in the classroom - a variety of applications and thematic sites. The information-communication technologies which allow to carry out search, collection, storage, processing, dissemination of information when learning a foreign language. When performing the tasks of the web quest, two experimental groups were identified in order to form pedagogical competence. The evaluation of group activities was carried out on the basis of news presentations of each column. Since the content and categories of web quests differed from each other, it was difficult to compare the results. However, the submissions of the students who prepared the web quests were found to be satisfactory and included in the results and assessment data sheet. Was recorded formed the competence, the possession of which determined the result in the performance of independent work on the web quest.
The content of matrix metalloproteinases in bladder cancer tumors

Bladder cancer (BC) is the 9th in frequency oncologic disease, with the highest number of patients in developed countries. The disease is more
commonly diagnosed in men – about 75%. The ability to invade surrounding tissues and metastasis to individual organs is one of the fundamental properties of malignant tumors. According to modern ideas about mechanisms of metastasis, basement membranes and extracellular matrix are the main barriers, and tissue structures are needed to overcome the invasive growth of tumor cells. Almost all of the extracellular matrix components can be destroyed by the use of metal-matrix proteinases (MMP), moreover, the precursors of growth factors and adhesion molecules on the cell surface may be the MMP substrates. MMPs also participate in epithelial-mesenchymal transformation, which provides metastasis. Previous studies by other authors point to an increase in the biosynthesis of various MMPs in the outbreak of tumors and in metastases, such changes associated with the degree of differentiation of the tumor, the depth of the invasion, as well as their association with poor further prognosis and low survival rates in patients with various cancers. The purpose of our work was to investigate the content of MMP-1, 2, 3, 8 and TIMP-1 in the tumors and walls of the healthy bladder in patients with BC, depending on the stage of TNM classification. We investigated the increase in the content of MMP-1, 2, 3, 8 and TIMP-1 in samples of healthy bladder walls for stage 3 and 4 of the BC, indicating the participation of the investigated parameters in the growth and invasion of bladder tumors. The results of our study are consistent with the results of previous studies conducted in the study of other neoplasms, which indicate the relationship between the studied parameters with the development of cancer.

The aim of the study was to investigate the effect of multiprobiotics on the content of products of oxidative modification of proteins and the level of sulfhydryl groups in blood serum of rats during monoiodoacetate-induced osteoarthritis. The study was carried out on white non-linear, sexually mature male rats (weight 180-240 g), according to general ethical principles of experiments on animals. All animals were divided into four experimental groups. The first group - Control: animals got injection into knee ligament 0.05 ml of 0.9% NaCl solution on the first day of the experiment and then got intragastric administration 1 ml of drinking water per 1 kg of the animal weight daily for 14 days from the 8th to 22nd days. The second group - Multiprobiotic: animals got injection into knee ligament 0.05 ml of 0.9% NaCl solution on the first day of the experiment and then got intragastric administration 140 mg/kg of multiprobiotic Symbiter® (Prolisok ", Ukraine) diluted in 1 ml of drinking water per 1 kg of animal weight. The third group, MIA-induced OA: animals got injection into knee ligament 1 mg of sodium monoiodacetate, dissolved in 0.05 ml of 0.9% NaCl on the first day of the experiment and then got intragastric administration 1 ml of drinking water per 1 kg of the animal weight daily for 14 days from the 8th to 22nd days. The fourth group – MIA-induced OA + Multiprobiotic: animals got injection into knee ligament 0.05 ml of 1 mg of sodium monoiodacetate, dissolved in 0.05 ml of 0.9 % NaCl on the first day of the experiment and then got intragastric administration 140 mg/kg of multiprobiotic diluted in 1 ml of drinking water per 1 kg of animal weight. All animals were killed on day 30 of the experiment, according to the protocol of the ethics committee with rapid blood sampling. The content of the products of oxidative modification of proteins (OMP) and oligopeptides was determined by the level of carbonyl derivatives that were detected in reaction with 2,4-initrophenylhydrazine. The level of total, protein-bound and non-protein sulfhydryl (SH) -groups was measured by the Elman method. It has been established that MIA-induced OA disturbed oxidative-antioxidant balance of the rat serum: the content of the products of oxidative modification of proteins increases and the content of sulfhydryl groups decreases in the serum. It was shown that with the long-term administration of multiprobiotics in animals with MIA-induced OA, the above indicators were restored.
INSTITUTIONAL SUPPORT OF CHILD PROTECTION POLICY

Ukraine’s independence in 1991 made the democratic transformations began, aimed to form the civil society, the development of a rule of law, within, according to the Constitution, a person, his life and health, honor, dignity, integrity and other rights and freedoms are recognized as the highest social value. This, in turn, defines the content and focus of the activities of the state and all its bodies in securing these conquests of world civilization as one of the main responsibilities.
It is not enough to declare them at the constitutional and legislative levels for the realization of fundamental rights and freedoms of the individual and the citizen. They must be fully secured through legal and social measures and their existence.
Among the various measures for the realization of human and citizen’s rights and freedoms, the Institute of International Protection of the Rights of the Child occupies a special place, as a set of international legal norms governing the international policy and cooperation of the states for the protection and protection of the rights of the child. As part of the international protection of human rights and freedoms, the child protection policy is of paramount importance.
It is the area that should take priority in the international political arena. The protection of the rights of the child is also important as a guarantee of the existence, implementation, and protection of the Constitution of Ukraine. The primary purpose of protection is the legally foreseen ability of the child to use compulsory actions to enforce his or her legal obligation to enforce the obliged person’s behavior in order to protect his or her right.
The urgency of gender is essential to accelerate the creation of an effective legal mechanism for the protection of the rights of the child. In addition, the existence of a real «legal protection» of the child as a whole, as well as of the state’s responsibility to the child, is the factor that asserts in the human consciousness the idea of justice, the expediency of the existing state power, thereby ensuring its legitimacy.
Formation of civil society and the integration of this country into the European community are impossible without a well-grounded state policy for the protection of the rights of the child. Therefore, the development of international cooperation in this field is especially relevant to Ukraine, since overcoming child neglect and homelessness, adopting children, preventing their involvement in the sex industry can only be ensured in close cooperation with other countries and using their experience
