Psychological features of professional stress of teachers
Authors: Savenkova Iryna , Kosenchuk Viktoriia
Published: February 2021

The article analyzes the key approaches to the phenomenon of stress in the teacher's professional activity. The views of scientists on its nature, the factors that give rise to its appearance and deployment are presented. The concepts of "work stress", "organizational stress", "professional stress" are distinguished. Professional stress among teachers is viewed through the prism of an individual's individual response to the impact of a difficult situation (psychological approach). The teacher's reaction to the increased demands of the social environment for his activities is investigated (social approach). The psychological state of the teacher, determined by the powerful action of factors associated with the implementation of professional tasks (professionally oriented approach) is described. The importance of an integrated approach to the study of psychological characteristics of professional stress of teachers is emphasized.
Currently, there is an acute lack of personal resources for the effective solution of current pedagogical problems, which leads to stress.
The author has characterized the types of professional stress by the nature of the impact on the personality of the teacher and his/her activities. The factors determining the transformation of situational stress into chronic occupational stress have been determined. The features of informational, emotional and communicative stress in the teacher's professional activity are described. The types of stressors in pedagogical activity are highlighted. Particular attention is paid to objective and subjective stressors, in particular to interpersonal, mid-personal and motivational. General and special occupational stressors are described in detail. The differences from stressors that are controlled and not amenable to control in the conditions of pedagogical activity are determined. Attention is focused on the fact that professional stress among teachers can become a serious threat to the successful deployment of professional activity and
lead to professional burnout. Cases in which professional stress becomes a stimulus prompting a teacher to develop and improve are identified.
Gender identity formation of female athletes which represents “male” sports
Authors: Chuhueva Inna
Published: February 2021

The article presents the results of a study of the gender identity of female athletes engaged in "male" sports. The components of gender identity, factors of its manifestation in the categories of femininity and masculinity are shown. It is pointed out that gender identity acts as a coherence of consciousness and the behavior of a person as a representative of a certain sex, the connection of cognitive and conative components of personality identity. The gender role requirement is the guideline for this coordination.
There are three components to gender identity: structural, dynamic and functional. Gender identity is also presented as a fundamental structure of social identity, which characterizes a person in terms of membership in a masculine or feminine group, the most significant being the way in which a person defines himself.
The analysis of the influence of sports activities on the formation of the gender identity of women athletes, representatives of various types of sports is done. Experimental data show that athletes strive to see the feminine qualities in themselves and to understand the presence of dominant masculine features, qualities and role models that develop sporting activities. The results showed that the great majority of female athletes strive to achieve a balance between masculine and feminine features, as shown by the highest percentage of androgyny.
In general, the results of the study show that the following concepts prevail in the perceptions of female athletes: "I am ideal" and "Typical male athlete". The lowest number of selections for the article "Typical female athlete". The results of the study showed that the majority of female athletes (28%) had a diffuse personal identity. This is the status of identity, in which there are no strong goals, values and beliefs and attempts to actively form them. In the sample, the vast majority (54%) of athletes also has a diffuse type of gender identity, that is to say, that these athletes have not yet formed their image of a woman or are not paying much attention to it. The lack of gender identity in the vast majority of respondents confirmed the importance of the influence of sports activities in power sports on the development of athletes'
gender identity.

Authors: Shevchenko Volodymyr , Yaremchuk Viktoriia
Published: February 2021

This article highlights the problem of bullying among teens. It is determined that the age characteristics that cause an increase in the level of aggression in adolescents include exacerbation of character accentuations, as well as increasing physical activity, which can be manifested in bullying, property damage and more. It is also worth noting
the active desire of children of this age for the attention, understanding and trust of adults. Teenagers are trying to play a certain social role not only with peers, but also with adults, to show a social activity that adults do not always support.
Therefore, when they are exposed to psychological barriers, without finding mutual understanding with others and their families, they try to overcome them by aggressive behavior.
It was found that closer to mid-teens; aggressive behavior tends to decline because of the increase in social skills for self-regulation.
However, despite the high coefficients of stability of aggressive behavior in the transition from childhood to adolescence, attention should be paid to individual variability in aggressive behavior.
Psychologists identify several main reasons: low self-esteem, home atmosphere and group atmosphere.
The results of the study of bullying among students of 9-11 grades of the Higher Vocational School № 21 in Mykolayiv are presented. The sample consisted of 75 persons, of whom 54 were boys and 21 were girls.
It was obtained that the psychological characteristics of the individual that may contribute to the emergence of bullying among students are at an average level, the indicators do not exceed the norm, respectively; pronounced characteristics of high school students in their propensity for bullying in the study group were not identified.
Given all the circumstances and factors involved in the formation of aggressive behavior in adolescents, you can prevent or limit the manifestation of aggressive behavior.
Today, there are numerous anti-bullying and prevention programs developed by a variety of institutions, including the Ministry of Education and Science of Ukraine, but each needs well-trained specialists for effective implementation, and the training of qualified psychologists is an effective tool to fight bullying.

Beef is a livestock product that has economic value. The high demand for meat requires farmers to cultivate cows by supplying cattle to meet consumer needs. In terms of selecting beef cattle seeds, independent breeders still do traditionally. During this time farmers still use the trial and error method in choosing the best type of cow even just concerned with the price factor. This will obviously affect the quality of cattle which results in expensive maintenance costs, less than optimal production yields and even death of cows. The purpose of this study was to conduct a study of the application of technology in the selection of the best beef cattle to increase livestock yield, especially for local independent breeders. The technology used is a combination of the Analytical Hierarchy Process (AHP) method and the Multy Factor Evaluation Process (MFEP) Method. Through a combination of methods, researchers analyzed each criterion and alternative related to the selection of the best beef cattle. AHP method was chosen because it has the ability to analyze more consistent criteria. While the selection of the MFEP method is due to having the ability to analyze alternatives based on existing criteria in a simple and accurate way. The results of the AHP and MFEP analysis method are AHP analysis to assist in determining the priority factors of beef cattle seedlings and applied to the MFEP method which produces the highest alternative A6 with a value of 0.508. This research is expected to become a new foundation for farmers in knowing the criteria and alternatives in determining the best type of beef cattle.
Energy-Saving Led Lighting System With Parallel Power Supply By Photovoltaic Modules And By Network
Authors: Tikhonov Pavel V.
Published: February 2021

The current state of LED lighting systems with parallel power supply by photovoltaic modules and central power supply network is analysed. The approach to implementation of parallel operation of LED luminaire powered by two sources of power is presented. It is simple, cheap and highly reliable as compared to the existing solutions. Based on this approach, four diagrams are developed which are applicable correspondingly to lighting applications and characteristics of photovoltaic modules and power consumers. The first and the second diagrams contain minimal quantity of transformers, but a number of operational constraints shall be taken into account when using them. The third diagram contains standard transformers and implies minimal number of various constraints, which makes it an optimal solution for the low-power lighting system being designed. The fourth diagram is expensive due to utilisation of equipment with automatic maximum power point tracking (the MPPT technology); it provides maximum possible energy efficiency of the lighting systems but the advantages of the MPPT technology apply only to high-power systems.
It is preferable to use such objects where lighting is mostly required during daytime as consumers of such systems (shopping malls, underground passages, storage facilities, poultry farms, etc.). A positive aspect is increase in reliability of consumer power supply since power supply of LED luminaires will be also provided by an additional source.
The proposed approach leads to reduction of power consumption for LED lighting, saving of fossil energy sources and therefore to ecologisation of the environment.

Authors: Guryleva Anastasiya V. , Khorokhorov Alexei M. , Kobozev Vitaly S.
Published: February 2021

The article proposes the methods of object shooting by means of a spectrometer based on a multi-channel radiation detector and further processing of its results allowing spectral resolution of such spectrometers significantly to increase with the same original spatial resolution. The mathematical model of the shooting process is provided. It is determined that restoration of spectral radiance of objects based on the shooting data using the proposed method is a mathematically incorrect inverse task. The Greville method, the method of wavelet transformation, the Tikhonov regularisation method, and the Godunov method were considered as methods for its solution. The results of computational modelling of the considered methods are shown and it is found that restoration of spectral radiance of objects based on the shooting data using the considered methods is possible and relative error of restoration is at a fraction of per cent scale. It is determined that the wavelet transformation method is an optimal method of solution of the incorrect spectral radiance restoration task. It is also shown that the proposed method of imaging spectrometry is applicable both when using matrix radiation detectors with increased number of narrow-band filters and when using widely spread standard three-channel matrix RGB detectors of radiation.

Evaluation And Selection Of Colour Spaces For Digital Systems
Authors: Zhbanova Vera L.
Published: February 2021

The research examined the changing of colour difference by the control colours depending on the choice of colour space when working with matrix photo detector. The spectral characteristics of photo detectors from different manufacturers noticeably differ from each other and from the addition the difference in colour quality between different digital devices. A software method for studying the colour rendition of the image obtained by digital devices based on the selection of an individual colour space for each matrix photo detector is proposed. To analyze and evaluate the capabilities of the spectral characteristics of matrix photo detectors, the control colour method based on the Mansell Atlas was used. The analysis of the obtained parameters of 14 colours was carried out according to various criteria for seven colour spaces: sRGB, AdobeRGB, DCI-P3 RGB, M1N1P1, PAL / SECAM, Wide Gamut RGB, ProPhoto RGB. Also studied the influence of the choice of colour space on the change in the coordinates of the source 6,500 K. Based on the colour differences of the control colours, it is possible to choose the optimal colour space for working with a specific matrix photo detector. The latter will reduce colour distortion at the initial stage of image registration. The ways for improving the colorimetric method of control colours are proposed as applied to digital devices at the software level.
Insolation And Covid‑19: Protection From The Aggressor
Authors: Popovskiy Yuri B. , Shchepetkov Nikolay I.
Published: February 2021

The article reviews the importance of insolation as a factor of prevention and containment of infectious diseases and epidemics. The authors consider insolation not as a mean of curing the Сoronavirus Disease (WHO fairly calls such possibility “a myth”) but as a means to lower the risks of dissemination of the infection, to reduce viability of the virus in the environment, to support human protective immune mechanisms affecting susceptibility of the population as a whole, severity and recovery time, i.e. both sanitary and hygienic and prevention factors of the COVID‑19 epidemic containment. Apart from the germicidal and virucidal sanitising effects of solar rays, the article reviews anti-epidemic capabilities of insolation as a microclimate factor and a psychological and physiological regulator of human protective capabilities as well as the insolation standards as a mechanism of development density regulation. It is impossible to efficiently combat massive dissemination of highly contagious infections without concerted utilisation of all available means and measures: both medical and preventive and organisational. The unprecedented mobilisation of healthcare systems and large-scale restrictive quarantine measures are under special attention of the society. This article reviews the importance of insolation as a universal natural anti-epidemic factor which is undeservedly placed in the end of the list of effective infection combating measures.

Published: February 2021

The main purpose of new studies investigating pantograph catenary interaction in electric rail systems is to detect malfunctions. In the pantograph catenary interaction studies, cameras with non-contact error detection methods are used extensively in the literature. However, none of these studies analyse lighting conditions that improve visual function for cameras. The main subject of this study is to increase the visibility of cameras used in railway systems. In this context, adequate illuminance of the test environment is one of the most important parameters that affect the failure detection success. With optimal lighting, the rate of fault detection increases. For this purpose, a camera, and a LED luminaire 18 W was placed on a wagon, one of the electric rail system elements. This study considered CIE140–2019 (2nd edition) standards. Thanks to the lighting made, it is easier for cameras to detect faults in the electric trains on the move. As a result, in scientific studies, especially in rail systems, the lighting of mobile test environments, such as pantograph-catenary, should be optimal. In environments where visibility conditions improve, the rate of fault detection increases.

Authors: Kaloshin Gennady A. , Budak Vladimir P. , Shishkin Sergey A. , Zhukov Vladislav V.
Published: February 2021

The paper discusses the possibility of remote detection of a continuous laser beam propagating in a scattering continental and coastal atmosphere, when it is recorded outside the axial zone. In the single scattering approximation, estimates of the radianceat the registration site are carried out, which are compared with the threshold characteristics of existing photodetectors in the visible and IR spectral regions. It is shown that the laser radiation (LR) of the beam is reliably recorded in the range of angles (0–180)° at metrological range of visibility equal (5–20) km at night conditions. At twilight, under the same conditions, detection capabilities are significantly reduced.
A significant increase of the LR beam radiance contrast with a decrease in its divergence has been shown experimentally in the field observations.
At twilight, a decrease in the beam’s radiance contrast is seen. A beam with a divergence equal to 2 ceases to be distinguishable at angles equal to (80–90)°, and a beam with a divergence of 4 – at angles (60–70)°.In this case, the contrast difference reaches up to 10 times.
Pengaruh Leverage, Opini Audit Tahun Sebelumnya, Pertumbuhan Perusahaan, dan Ukuran Perusahaan terhadap Opini Audit Going Concern
Authors: Halim Kusuma Indawati
Published: February 2021

Audit reports are used by auditors to inform the accuracy of the information in the financial statements. The auditor as an independent party has the competence to provide an opinion on the client's financial condition. If it is estimated that the company cannot continue its activities, it is likely that it will get a going concern audit opinion. Audit opinion can help investors and other stakeholders in assessing the status of the company's business continuity. The important thing from a going concern audit opinion is to provide additional information for investors in making investment decisions. This study analyzes the factors that determine going concern audit opinion on manufacturing companies listed on the Indonesia Stock Exchange. The factors tested in this study are leverage, initial opinion, company growth and company size. The study used a sample of 125 companies for the 2014-2018 period. The results of data analysis were obtained from logistic regression tests. The empirical results show that prior opinion and leverage increase the likelihood of receiving a going concern opinion. Meanwhile, company growth and company size have no effect on going concern audit opinion. Nagelkerke's R Square test shows the ability of the factors in this study to explain 63.1% of going-concern audit opinion, while 36.9% is explained by other factors outside the research model. The findings from this study are expected to help investors and other stakeholders to prevent losses if they invest in companies that have the potential to go bankrupt.

Authors: Pereira Bruna Louise Adona Reis , Sorte Eveline da Cruz Boa , Borges Jaqueline Camargo , Mendonça Adriane Jorge
Published: February 2021

A babesiose é uma zoonose causada por diferentes espécies de protozoários do gênero Babesia, que obrigatoriamente vivem no interior das células sanguíneas. Transimitida por carrapatos ixodídeos, ela pode acometer tanto animais domésticos, quanto silvestres. No Centro-Oeste, apesar de já existirem descrições da hemoparasitose, pouco se sabe referente à sua ocorrência, sendo a maioria dos estudos referentes à detecção por meio de diagnósticos moleculares. Apesar disso, o esfregaço sanguíneo mostra-se um método diagnóstico fundamental, principalmente, por ser um exame de triagem, viável, altamente conclusivo e de baixo custo. Este estudo objetivou enfatizar a importância do esfregaço sanguíneo como diagnóstico da enfermidade. Realizou-se um levantamento dos achados de Babesia spp. em esfregaços sanguíneos da rotina do HOVET – UFMT, durante o período de doze meses, bem como foi buscada a existência de um perfil hematológico, visando validar a suspeita mesmo em casos de baixa parasitemia. Foram processados 5.333 hemogramas caninos, destes, os que apresentaram o trofozoíto da Babesia spp. na citologia dos esfregaços foram submetidos à avaliação do resultado de seus exames. Foi constatado que mesmo em casos que a citologia resulte negativa, com o histórico clínico associado ao perfil hematológico é possível validar a suspeita da hemoparasitose. Verificou-se a ocorrência de 0,3% de babesiose em cães, sendo a maioria dos achados esporádicos. Os principais achados hematológicos foram anemia (68,75%) normocítica normocrômica (45,45%), trombocitopenia (87,5%), leucopenia (75%), eosinopenia (68,75%), linfopenia (87,5%) e monocitose (18,75%).

O objetivo deste trabalho foi realizar o levantamento fitossociológico de plantas daninhas no cultivo de couve-folha em consorciação com o quiabeiro. O experimento foi conduzido em blocos casualizados, com quatro repetições. Os tratamentos foram constituídos pelos seguintes arranjos:  T1 (três linhas de couve com quiabeiro nas entrelinhas), T2 (três linhas de couve com quiabeiro a cada duas entrelinhas), T3 (três linhas de couve com quiabeiro adensado nas entrelinhas), T4 (três linhas de couve com quiabeiro adensado a cada duas entrelinhas), T5 (couve), T6 (quiabeiro), T7 (quiabeiro adensado) e T8 (palhada de aveia). Aos 17 dias após o transplante (DAT) e em intervalos quinzenais até 152 DAT foram realizadas amostragens com quadro de 0,09 m2, aleatoriamente em cada parcela. As plantas daninhas foram quantificadas e identificadas estabelecendo-se o número total de indivíduos e a densidade total de plantas por m². Ao final de 77 e 152 DAT estabeleceu-se a frequência absoluta, frequência relativa, densidade absoluta, densidade relativa, abundância absoluta, abundância relativa e o índice de valor de importância das espécies mais representativas. Identificou-se 23 espécies distribuídas em 14 famílias, destacando a família Asteraceae, com 5 espécies. As espécies mais importantes foram Sonchus oleraceus e Richardia brasilenses, presentes em no mínimo 5 dos 8 tratamentos. O consórcio T1, teve redução de 38% no número de indivíduos e de 37,9% na densidade de plantas por m² em relação ao cultivo de couve-folha solteiro. O consórcio de couve-folha com quiabeiro reduz a infestação de plantas daninhas e pode ser explorado como alternativa de manejo.

Introdução: A pandemia do COVID-19, ocasionada pelo SARS-CoV-2, provoca desde infecções assintomáticas até a síndrome respiratória aguda grave, que por vezes, pode ser fatal, necessitando de enfrentamento. Objetivo: Analisar a epidemiologia da COVID-19 nas seis mesorregiões do estado do Pará, correlacionando-a com Índice de Desenvolvimento Humano Médio (IDHm) e o Percentual de Tratamento de esgoto do Estado. Métodos: Trata-se de um estudo descritivo transversal com abordagem quantitativa, realizado através do levantamento de dados secundários dos casos de COVID-19, coletados no período de 07 de março a 30 de maio de 2020, e dados sócio-demográficos das seis mesorregiões do estado do Pará. Resultados: Foram notificados 267.700 casos confirmados da COVID-19 em todo o estado do Pará. As mesorregiões do Sudeste paraense e da Região Metropolitana de Belém, apresentaram os maiores valores, com 81.556 e 71.117, respectivamente. Não houve diferença de número de casos entre os gêneros, porém as duas faixas etárias mais acometidas pela infecção estão entre 30 a 39 anos (64.138 casos) e 40 a 49 anos (51.535 casos). Dentre as comorbidades mais prevalentes estão as Cardiopatias e o Diabetes. Conclusão: As maiores taxas de incidência da COVID-19 estão concentradas nas mesorregiões com grande fluxo de pessoas, havendo uma tendência dos aspectos sociodemográficos se relacionarem com a epidemiologia da COVID-19 nas mesorregiões do estado do Pará.
O professor remoto: a reinvenção da prática pela fluência digital
Authors: Veloso Augusta Maria Fontes , Briccia Viviane
Published: February 2021

O presente artigo apresenta uma revisão bibliográfica, que é parte de uma pesquisa em construção, sobre o desenvolvimento da fluência digital na reinvenção da prática docente, no contexto atual mediado pela tecnologia. O objetivo deste texto é dialogar com os principais estudos nas áreas de Práticas Pedagógicas e Tecnologia, para identificar lacunas que ainda possam ser preenchidas na pesquisa em Educação. O levantamento bibliográfico foi realizado a partir de busca na base de dados da Biblioteca Eletrônica Scielo, dos quais foram selecionados três artigos. Este estudo aponta que, embora os recursos tecnológicos no contexto da necessidade do ensino remoto estejam presentes e atrelados a um processo de reinvenção da prática pedagógica, não haverá a garantia de desenvolvimento da fluência digital se não ocorrer um investimento na formação docente para o uso das tecnologias na Educação.

A biossorção de minerais é uma técnica que pode trazer ganhos significativos na produção de biomassa funcional. Os resultados podem garantir economia (por não adicionar minerais na biomassa seca), minimização do tempo e eliminação de etapas no processo produtivo. O objetivo do presente trabalho foi estudar a incorporação de zinco, magnésio, ferro e selênio na biomassa de Spirulina platensis por meio da aplicação de Planejamento Fatorial Composto Central. Os experimentos foram conduzidos em casa de vegetação em fotobiorreatores de 10 litros, tendo por objetivo a biossorção máxima dos minerais em cinco dias. Foi observada influência significativa na incorporação de magnésio (410 mg.100-1g) e zinco (34,84 mg.100-1g). Também foi observado na incorporação de Fe (73,5 mg.100-1g) e selênio (1.738,81 mg.100-1g), evidenciando o potencial de uso da técnica para incorporar esses minerais na biomassa de Spirulina platensis e garantir ampla aplicação desta matéria prima em alimentos e suplementos.
Tratamento da osteonecrose dos maxilares associada ao uso de medicamentos - revisão de literatura
Authors: Almeida Arthur Caetano de , Paulo Luiz Fernando Barbosa de , Vasconcelos Luana Soares , Lima Lívia Bonjardim
Published: February 2021

Introdução: A osteonecrose dos maxilares associada ao uso de medicamentos é uma doença que se dá pelo uso de terapias com drogas antirreabsortivas, como bisfosfonatos e Denosumab, ou antiangiogênicos. Embora a manifestação desta doença não tenha alta incidência, sua ocorrência gera um impacto significativo na vida do paciente, levando à sintomatologia dolorosa, com supuração e odor fétido. Apesar dos vários tratamentos empregados, não existe um consenso acerca da maior eficácia de um tratamento frente a outro. Assim, este trabalho objetiva demonstrar as diferentes modalidades de tratamento e os benefícios aliados a cada uma. Materiais e Métodos: Buscas feitas na base de dados PubMed/MEDLINE sobre o tema Osteonecrose dos Maxilares Associada ao Uso de Medicamentos, aliado a operadores boleanos, durante os meses Maio, Junho e Julho de 2020. Resultados: A pesquisa resultou em 143 artigos e, após a aplicação dos critérios de elegibilidade, 49 foram selecionados (23 estudos prospectivos, 17 retrospectivos e 9 séries de caso), englobando 2617 pacientes e 2848 lesões. Os tratamentos foram divididos em 5 modalidades (terapias adjuvantes, tratamentos cirúrgicos agressivos, terapias teciduais, tratamento assistido por medicamentos e terapias cirúrgicas conservadoras).Conclusão: Vários tratamentos são propostos e parece claro que as cirurgias agressivas são as terapias com melhores resultados, sobretudo quando aliadas a uma terapia tecidual ou adjuvante. As cirurgias conservadoras apresentam papel importante, principalmente, em pacientes portadores de condições sistêmicas que contraindiquem as cirurgias maiores.
Forest cover influences chytrid infections in populations of Boana curupi, a threatened treefrog of south Brazil

Complex interactions among hosts, pathogens, and the environment affect the vulnerability of amphibians to the emergence of infectious diseases such as chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd). Boana curupi is a forest-dwelling amphibian endemic to the southern Atlantic Forest of South America, a severely fragmented region. Here, we evaluated whether abiotic factors (including air and water temperature, relative air humidity, and landscape) are correlated with chytrid infection intensity and prevalence in B. curupi. We found individuals infected with Bd in all populations sampled. Prevalence ranged from 25-86%, and the infection burden ranged from 1 to over 130000 zoospore genomic equivalents (g.e.) (mean ± SD: 4913 ± 18081 g.e.). The infection load differed among populations and was influenced by forest cover at scales of 100, 500, and 1000 m, with the highest infection rates recorded in areas with a higher proportion of forest cover. Our results suggest that the fungus is widely distributed in the populations of B. curupi in southern Brazil. Population and disease monitoring are necessary to better understand the relationships between host, pathogen, and environment, especially when, as in the case of B. curupi, threatened species are involved.
Law and religion in “Martian the Lawyer”, the dramatic poem by Lesia Ukrainka
Authors: Dagovych Tetyana
Published: February 2021

The paper explains the attitudes towards law and religion in Lesia Ukrainka’s dramatic poem “Martian the Lawyer” (1911). The poem depicts the life of early Christians under the Roman law in the third century and obtains new relevance in the context of the movement ‘Law and Literature’, as the focus on law in this oeuvre allows a deeper exploration of its meaning. Law is connected with religion in two ways in the poem: as a part of the civil religion and as a system of prohibitions and punishments within the Christian community. Analysis of the text shows that Martian is a carrier of a sophisticated religious form, which implies the juridical elements codified in early Christianity, as well as a belief in law as the incarnation of the idea of truth and justice. The two antagonistic social and spiritual systems – early Christianity and the Roman law – fuse into one ideology that consumes the life of the protagonist. The difference between the juridical laws, the law of nature, and the commandments of Christian leaders disappears within this religious form. In the house of the hero, only those things that represent time or law remain, such as different types of timepieces and juridical texts; Martian’s home becomes a place for abstract ideas, but not for human beings with their needs and feelings. For the protagonist, there are no conflicts between law and religion, but there is a conflict between early Christianity and the Roman law on the one side and, on the other side, human compassion, which is supposed to be a crucial idea within Christianity but is not practiced in the local Christian community. Because of this conflict, Martian completely loses contact with human feelings and becomes an ideal lawyer, which is beneficial for his Christian community but tragic for himself and his relatives. This development signifies not only a sacrifice but also the full realization of Martian’s talent (Ukrainian: ‘khyst’). In some episodes within other poems by Lesia Ukrainka, law and religion are presented as intertwined or undifferentiated, but in “Martian the Lawyer” the author for the first time elaborates this issue thoroughly and creates an ambivalent and sophisticated dramatic situation.
