This experiment was conducted to study the effect of soil type (structure) and different dumping depths of larvae and pupae within the soil on the emergence rate of adults of the Mediterranean fruit fly, Ceratitis capitata, which is considered a major pest affecting citrus and stone fruits orchards. Three soil types were selected: sandy clay, clay loam and loam and for each type six dumping depths were tested (3, 5, 7, 10, 15 and 20 cm).The results showed that the soil type had a significant effect on the adults emergence rate, and the highest rate was recorded for the sandy clay soil, when using the last larval instars (pre-pupae) and pupal stages, and reached 55.28 and 51.66%, respectively. The results also showed that the soil type and dumping depth together have a significant effect on the adults' emergence rate of the Mediterranean fruit fly. The sandy clay soil and the two depths, 5 and 7 cm, gave the highest emergence rate which was 73.3 and 71.67%, respectively, when using the last larval instar. Whereas, the clay loam soil gave at 3 and 5 cm soil depths a 70% emergence rate for both dumping levels. The results also showed that the two soil types sandy clay and loam showed that the emergence of adults continued even at 20 cm depth. The results obtained in this research can be incorporated to the practices used for the integrated management of the Mediterranean fruit fly C. capitata. Keywords: Mediterranean fruit fly, soil type, soil depth, adults' emergence rate.

Published: April 2022

Introduction. Currently, the role of the Military Medical Academy is named after S. M. Kirov in the development of the world and domestic medical science, as well as in the creation of scientific medical schools. Despite the fact that the Department of Dentistry at the Military Medical Academy was formed in 1929, the influence of the Academy on the development of domestic dentistry can be traced throughout the entire period of its existence. However, not all historical moments of the formation and development of military dentistry are known to a wide range of specialists.

The purpose of the study was to highlight the merits of the marine doctor, doctor of medicine, privat-docent P. F. Fedorov, pointing out his role in the formation and development of dentistry in our country.

Published: April 2022

One of the biggest interests for companies in today’s market is considered consumer preference, why they make the choice of one product over another. The main aim of this study is to analyse the impact of neuromarketing in the process of identifying the preferences and needs of consumers. Neuromarketing tools provide insights into measuring the effectiveness of advertising campaigns in making an impact on the consumers in online retailing (Singh, 2020). In this study, neuromarketing has been analyzed, understanding the structure of the brain and its functions, the importance of perception, as well as consumer behavior during the purchasing process. In general, it is assumed that these choices are developed in a logical way, selecting the option that represents the greatest utility (Blazquez-Resino, Gutierrez-Broncano, & Gołąb-Andrzejak, 2020). The method used for primary data collection is the questionnaire, which addresses elements that are important in choosing a product for a customer. This study concludes that neuromarketing contributes to the discovery of consumer preferences thus helping companies to be closer and meet the needs of consumers. The recommendation of this paper is to use neuromarketing in identifying customer preferences
A Lesser Scaup ( Aythya affinis ) Naturally Infected with Eurasian 2.3.4.4 Highly Pathogenic H5N1 Avian Influenza Virus – Movement Ecology and Host Factors

Published: April 2022

Despite the recognized role of wild waterfowl in the potential dispersal
and transmission of highly pathogenic avian influenza (HPAI) virus,
little is known about how infection affects these birds. This lack of
information limits our ability to estimate viral spread in the event of
an HPAI outbreak, thereby limiting our abilities to estimate and
communicate risk. Here we present telemetry data from a wild Lesser
Scaup ( Aythya affinis), captured during a separate ecology study
in the Chesapeake Bay, Maryland. This bird tested positive for infection
with clade 2.3.4.4 HPAI virus of the A/goose/Guangdong/1/1996 (Gs/GD)
H5N1 lineage (results received post-release) during the 2021-22 ongoing
outbreaks in North America. While the infected bird was somewhat lighter
than other adult males surgically implanted with transmitters (790g,
mean=868g, n=11), it showed no clinical signs of infection at capture,
during surgery, nor upon release. The bird died 3d later, pathology
undetermined as the specimen was not able to be recovered. Analysis of
movement data within the 3d window showed that the infected individual’s
maximum and average hourly movements (3894.3m, 428.8m respectively) were
noticeably lower than noninfected conspecifics tagged and released the
same day (mean =21594.5m, mean =1097.9m, respectively; n=4). We
identified four instances where the infected bird had direct contact
(fixes located within 25m and 15 min) with another marked bird during
this time. Collectively, these data suggest that the HPAI positive bird
observed in this study may have been shedding virus for some period
prior to death, with opportunities for direct bird to bird or
environmental transmission. Although limited by low sample size and
proximity to the time of tagging, we hope that these data will provide
useful information as managers continue to respond to this ongoing
outbreak event.
Positive Selection Drives the Rapid Fixation of Dephosphorylation in IRF9
Authors: chen jianhai , He xuefei , Jakovlic Ivan
Published: April 2022

The arms race between humans and pathogens drives the evolution of the
human genome. Here, based on the HPO (Human Phenotype Ontology)
annotation, we focused on human genes related to recurrent infections of
virus, (RVI), bacterial (RBI) and recurrent fungal infections (RFI) to
understand positive selection on pathogen-responsive genes.
Interestingly, cross-species positive selection analyses revealed that
the proportion of unique genes under positive selection was higher for
RVI (78.57%) than for RFI (57.14%) and RBI (58.68%). Based on results
of the branch-site test, we further focused on the amino acid site
Val129 of IRF9, which has a significant signal of positive selection
based on multiple evidence. Interestingly, this novel and derived amino
acid (V) has been rapidly fixed before the “out-of-Africa” event
~500,000 years ago from the ancestral state S, which is
conserved among 88.5% of mammalian lineages. Phosphorylation analysis
revealed that the conserved ancestral S may serve as the phosphorylation
site of IRF9. Further analyses suggested that the rapid
dephosphorylation of IRF9 via the change of S to V may have conferred
potential molecular adaptations by boosting and extending the immune
activity of IRF9. This study provides an interesting mode in which
strong positive Darwinian selection drives the rapid fixation of a
hominin specific amino acid leading to molecular adaptation for immune
response.
The role of respiratory co-infection with influenza or respiratory syncytial virus in the clinical severity of COVID-19 patients: a systematic review and meta-analysis
Authors: cong bingbng , deng shuyu , wang xin , Li You
Published: April 2022

Aim: To understand the impact of influenza/RSV co-infection on clinical
disease severity among COVID-19 patients. Methods: We conducted a
systematic literature review of publications comparing the clinical
severity between the co-infection group (i.e., influenza/RSV with
SARS-CoV-2) and mono-infection group (i.e., SARS-CoV-2), using the
following four outcomes: need or use of supplemental oxygen, intensive
care unit (ICU) admission, mechanical ventilation and deaths. We
summarized the results by clinical outcome and conducted random-effect
meta-analyses, where applicable. Results: Twelve studies reporting a
total of 7862 COVID-19 patients were included in the review. Influenza
and SARS-CoV-2 co-infection was found to be associated with a higher
risk of ICU admission (5 studies, OR: 2.09, 95% CI: 1.64-2.68) and
mechanical ventilation (5 studies, OR: 2.31, 95% CI: 1.10-4.85). No
significant association was found between influenza co-infection and
need/use of supplemental oxygen or deaths among COVID-19 patients (4
studies, OR: 1.04, 95% CI: 0.37-2.95; 11 studies, OR: 1.41, 95% CI:
0.65-3.08, respectively). For RSV co-infection, data were only
sufficient to allow for analyses for the outcome of deaths, and no
significant association was found between RSV co-infection and deaths
among COVID-19 patients (3 studies, OR: 5.27, 95% CI: 0.58-47.87).
Conclusions: Existing evidence suggests that co-infection with influenza
might be associated with a 2-fold increase in the risk for ICU admission
and for mechanical ventilation among COVID-19 patients whereas evidence
is limited on the role of RSV co-infection. Co-infection with influenza
does not increase the risk of death in COVID-19 patients.

In this study, raw natural gas data from Uch gas field located in Dera-Bugti of Balochistan, Pakistan is simulated for performance analysis over amine absorber unit in Aspen HYSYS V9.0. The primary amine, MDEA was selected to remove bulk CO2 and reduce H2S to ppm level, where secondary amines, MEA, DEA and Sulfolane were selected to observe CO2 levels in sweet gas. The primary amine in isolation and blend with secondary amine was simulated and analysed over absorber performance. The absorber performance is reported as CO2, H2S and water content in sweet gas, hydrocarbons in rich amine and its temperature. MDEA in isolation resulted in minimum 14.13 and 12.78 mol% CO2 in sweet gas and rich amine temperature of 81.11oC and 82.13oC with 24 and 30-Trays, respectively at 2500 m3 /h of lean amine recirculation rate. Among the tested blends, MDEA/MEA, MDEA/Sulfolane showed no significant improvement on absorber performance compared to isolated MDEA. However, MDEA/DEA blends indicated that CO2 in sweet gas can be reduced to 12.07, 3.41, 1.85 mol% with rich amine temperature of 89.05, 111.72 and 124.80oC, respectively. The lowest CO2 detected of 1.85 mol% was achieved with 40 mol% MDEA and 15 mol% DEA blend at 2500 m3 /h recirculation rate and rich amine temperature of 124.80oC. The results indicated that MDEA/DEA blend has the potential to attain CO2 of less than 2 mol%. The higher rich amine temperature raise concern that can be resolved by using heat stabilized salt.

Published: April 2022

Due to the consequences of global software development (GSD), the traditional approaches of software development evolved into lightweight agile methods. The agile methods got overwhelming response from software development companies due to their obvious support to GSD. In this regard, limited research work has been presented on software process evolution and process paradigm shift in context of GSD. Most of the work presented on GSD mainly focus on the companies in Europe, America, Australia and other western countries. Existing research work highlight the standard benefits and challenges of GSD but do not investigate its effect on software development processes and associated reasons causing the affect particularly in Malaysian software development companies. The research work presented in this paper addresses this issue and investigates the effects of GSD on software processes, software process evolution and paradigm shift and finds the current software processes being used in Malaysian companies. Also, it further determines the GSD factors and reasons behind the change and selection of a software development process. GSD factors affecting the software processes have been termed as challenges. Structured interviews have been conducted to collect qualitative data from industry professionals involved in GSD. General inductive approach has been used for qualitative data analysis and findings. The results show that after GSD, Malaysian companies are mostly following agile methods. The traditional and ad-hoc approaches used before GSD have been replaced by the lightweight agile methodologies. Few of the companies are still following ad-hoc approaches mainly due to size of the project and company as most of the Malaysian companies are small and medium size. The research is significant that it provides clear insight into software process paradigm in Malaysian companies. The outcome of the research provides foundations for the standardization of software processes, process improvement, selection and quality enhancement approaches in Malaysian companies.

In this article, we first construct family of two-step optimal fourth order iterative methods for finding single root of non-linear equation. We then extend these methods for determining all the distinct as well as multiple roots of single variable non-linear equation simultaneously. Convergence analysis is presented for both the cases to show that the optimal order of convergence is 4 in case of single root finding method and 6 for simultaneous determination of all distinct as well as multiple roots of a non-linear equation. The computational cost, basins of attraction, computational efficiency, log of residual fall and numerical test functions validate that the newly constructed methods are more efficient as compared to the existing methods in the literature.

Agricultural Insurance is a valuable business risk management tool that provides farmers with financial protection against production losses caused by natural perils, such as drought, excessive moisture, hail, frost, wind and wildlife. The study made use of a survey research design and 50 farmers from Ijebu Igbo local government of Ogun State were administered questionnaires. The findings showed a positive significant correlation (r = .638, p <.01) between Agriculture Insurance scheme and economic growth. Also, Credit Scheme and Agricultural Insurance jointly significantly influenced economic Growth [(R2 = .543; F (2,49) = 27.978; p < .05)] which infers that Credit Scheme and Agricultural Insurance jointly accounted for about 54.3% of the variance observable in Economic growth. The study recommends that more awareness on agricultural insurance should be made to farmers and the need to be aware of the security the insurance scheme offers them which in actual sense will bring about increase in yield at minimum cost.

Published: April 2022

Fly ash which is solid waste can be used as an adsorbent for wastewater
treatment. Alkali modification and alkali activation on fly ash can increase
the adsorption capacity of fly ash. In this study, alkali modified fly ash
and alkali activated fly ash were used as Zn(II) ions adsorbents. The effect
of adsorption time and initial concentration of Zn(II) ions was studied, as
well as the kinetics and isotherm adsorption. The results showed that the
removal efficiency of Zn(II) ions by alkali activated fly ash is higher than
that by alkali modified fly ash. The adsorptions of Zn(II) ions by alkali
modified fly ash and by alkali activated fly ash have reached equilibrium
after two hours. The increase of initial concentration of Zn(II) ions would
decrease the removal efficiency with both alkali modified fly ash and alkali
activated fly ash. Adsorptions of Zn(II) ions by both alkali modified fly
ash and alkali activated fly ash tend to follow pseudo second order kinetics
model and Langmuir isotherm model with maximum adsorption capacity of 62.696
mg/g and 66.667 mg/g, respectively.

Published: April 2022

In this study, the structure, morphology and composition of the synthesized
magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and
its adsorption performance with respect to As(V) and Cr(VI) were studied.
Magnetite (MG) modified 3D printed wollastonite was obtained by two step
procedure: modification of 3D_W with 3-aminoproylsilane (APTES) followed by
controlled magnetite (MG) deposition to obtain 3D_W/M adsorbent. The
structure/properties of 3D_W/M were confirmed by applying FTIR, XRD, TGD/DTA,
and SEM analysis. The adsorption properties of hybrid adsorbents were carried
out for As(V) and Cr(VI) removal - one relative to the initial pH value, the
adsorbent mass, the temperature, and the adsorption time. Time-dependent
adsorption study was best described by pseudo-second order equation, while
Weber Morris analysis showed that intraparticle diffusion controled
diffusional transport. Similar activation energy, 17.44 and 14.49 kJ?mol-1
for adsorption As(V) and Cr(VI) on 3D_W/M, respectively, indicated main
contribution of physical adsorption. Determination of adsorption parameters
was performed by applying different adsorption isotherm models, and the best
fit was obtained using Freundlich model. The adsorption capacity of 24.16 and
29.6 mg g-1 for As(V) and Cr(VI) at 2?C, Co = 5.5 and 5.3 mg L-1,
respectively, were obtained. Thermodynamic study indicated favourable process
at a higher temperature. Preliminary fixed-bed column study and results
fitting with Bohart-Adams, Yoon-Nelson, Thomas, and Modified dose-response
model showed good agreement with results from the batch study.

Published: April 2022

Dermatitis herpetiformis is a blistering autoimmune skin disease, and a cutaneous manifestation of coeliac disease. The burden of coeliac disease is increased especially in females, but studies concerning sex differences in patients with long-term treated dermatitis herpetiformis are scarce. This questionnaire study compared adherence to a gluten-free diet, clinical symptoms and well-being between females and males in a cohort of 237 long-term treated (median 24 years) patients with dermatitis herpetiformis. Females had better adherence to a gluten-free diet (p = 0.022) and they used dapsone significantly less often at the time of the study than did males (4% vs 13%, p = 0.017). The occurrence of skin symptoms was equal in both sexes, but dermatological quality of life was lower in females (p = 0.024), and gastrointestinal symptoms were more severe among females with dermatitis herpetiformis than among males (p = 0.027). In conclusion, long-term treated female patients with dermatitis herpetiformis have better adherence to a gluten-free diet, but they also experience more severe clinical symptoms compared with males.

The aim of this study was to determine whether COVID-19 restrictions had an impact on Chlamydia trachomatis infections compared with 2018 and 2019. A retrospective nationwide observational study was performed using monthly incidences of laboratory-confirmed chlamydia cases and number of tests, obtained from Danish national surveillance data. Testing rates and positivity rates were compared using Poisson and logistic regression. The first Danish COVID-19 lockdown (12 March to 14 April 2020) resulted in a reduction in the number of chlamydia tests performed (rate ratio 0.72, 95% confidence interval  0.71–0.73) and a consequent reduction in the number of laboratory-identified cases (66.5 vs 88.3 per 100,000 population during the same period in 2018 to 2019). This period was followed by a return of testing and test positivity close to the level seen in 2018 to 2019. The second Danish COVID-19 lockdown (17 December to 31 March 2021) resulted in crude incidence rates of laboratory-confirmed chlamydia infection that were similar to the crude incidence rates seen during same period in 2018 to 2019. In conclusion, the Danish COVID-19 restrictions have had negligible effects on laboratory-confirmed C. trachomatis transmission.

Based on the mechanism of dynamic coupling between molten pool and keyhole, a three-dimensional (3D) transient model for the dual-beam laser welding of aluminum alloy is established by considering the surface tension, Marangoni force, and recoil pressure. The morphology of the molten pool, porosity formation process, and the heat transfer mechanism during the process of laser welding under different parameters are analyzed. A double rotating 3D Gaussian heat source is used to represent the laser beam, and the volume of fluid method is used to track the gas-liquid free surface, and the gas-liquid interface force is transformed by the continuous surface force model. The results show that in the process of dual-beam welding, the interaction between the two keyholes enhances the fluid flow perpendicular to the spot line, and the shape of weld pool surface changes from elliptical to circular. Furthermore, welding speed and spot spacing have a significant effect on the shape of the molten pool. Furthermore, it is observed that dual-beam welding can improve the stability of the keyhole and reduce the maximum oscillation amplitude and the number of keyhole breakups. At a specific spot spacing, a unique process of separation and fusion is discovered in addition to the common stages of growth, maintenance, breakup, and shrinkage of the keyhole. The simulation results are in good agreement with the existing experimental results. Overall, this paper provides useful insights into the dynamics of the molten pool in dual-beam welding and reveals the molten pool behavior and porosity formation mechanism.

In this chapter, we discuss the ambivalent experiences of gender that we find present among musicians working in Norway. Even if the field of music of today is more inclusive and equal than before, musicians still face certain gendered practices and structures in their professional careers. Through the theoretical concept of ambivalence (Ashforth et al., 2014; Bauman, 1991; Merton, 1976), we here identify three ambivalences related to gender: 1) ambivalent roles and positions, 2) discursive ambivalence, and 3) ambivalence in visibility. Finally, we discuss how ambivalent experiences leads to different responses and actions among musicians in different areas within the field of music.
Musikeres profesjonelle seighet

This chapter discusses musicians’ professional resilience. On the backdrop of several changes that have affected the conditions for musicians’ work, such as increasing competition, relatively low income and the Covid-19 pandemic, one could assume that the music profession is associated with too much risk and is therefore less attractive. In a qualitative interview study of professional musicians in Norway conducted during the pandemic, however, musicians express in different ways that their work and profession is a source of well-being. We identify four strategies and cultural resources that form the basis of musicians’ professional resilience. First, musicians have strong experiences of meaning related to music, experiences that have intellectual, emotional, bodily and social elements. Second, musicians creatively adapt their work to changing conditions. Third, musicians have strategies for reducing their vulnerability in a competitive environment by anchoring their identity in aspects of their work that they feel confident about. Fourth, musicians express resistance against cultural policy expectations on becoming entrepreneurs. A discussion of the potential long-term effects of the Covid-19 pandemic on the professional resilience of musicians is also included in this article.
Reinterpretación semiótica para las pantallas en el diseño y las artes
Authors: Dávila Ulloa Adriana
Published: April 2022

La convergencia de medios, la conformación de nuevos lenguajes y los desarrollos tecnológicos, principalmente en la fibra óptica y el 5G, han permeado indiscutiblemente las formas de creación, producción, interpretación y difusión en el diseño y las artes. Se reinterpretará el proceso comunicativo entre dos máquinas propuesto por Umberto Eco para contrastar las modificaciones provocadas por la interacción digital. Actualmente, gracias a las pantallas es posible acceder a un sin número de aplicaciones, productos o servicios, sin embargo, es vital aprender, reinterpretar y asociar desde la semiótica las nuevas estructuras que se crean en un nuevo contexto: el digital.
De la subjetividad dual al efecto Eros. Cuerpos virtuales sensibles
Authors: Toledo Ramírez Francisco Gerardo
Published: April 2022

Los términos teóricos sentient emanating bodies, subjetividad dual y efecto Eros se examinan en el contexto del metaverso. Éste se constituye como un conjunto de arreglos técnicos, subjetivos y de comportamiento social, desencadenados por vivir, comunicarse e interactuar en línea conectados permanentemente a las redes de información y las sociales. En el metaverso, cualquier cuerpo sensible es capaz de “sentirse a sí mismo” y al mundo, incluso a nivel masivo, precediendo y superando percepción, lenguaje y ubicación física. Esa articulación se integra por the vibe, la autoempatía y la subjetividad dual, constitutivas de la transferencia entre producción de sensibilidad y subjetividad en el metaverso.

Hemimasticatory spasm. Own experience of using botulinum neuroprotein type A
Authors: Korenko A. N. , Amelin A. V. , Timofeeva A. A.
Published: April 2022

Нemimasticatory spasm (HMS) is a rare disorder of the nervous system, in which there are unilateral, violent spasms of the masticatory muscles innervated by the motor portion of the trigeminal nerve. The causes of HMS remain largely unexplored, but microvascular compression is most likely. Anticonvulsants, surgical treatment and botulinum therapy can be applied for the treatment of HMS.

We presented a clinical case of HMS in a 38-year-old woman who had been suffering from this disease for 18 years. The diagnosis of HMS was established only 10 years after the first visit to the doctor. Spasms could occur up to several hundred times a day with a duration up to 15 seconds. The magnetic resonance imaging allowed to exclude neurovascular conflict. Electroneuromyography revealed axonal lesion of the right trigeminal motor root and spontaneous activity in the right masseter muscle. Anticonvulsant treatment was ineffective. The patient received botulinum therapy with a good treatment result.

The objective was to evaluate the levels of neurotrophins in the brain of mice with urokinase (uPA) gene knockout, carriers of B16/F10 melanoma developing in presence of comorbid pathology – chronic neurogenic pain (CNP).

Methods and materials. The study included female mice of two strains: С57ВL/6 (n=40) and C57BL/6-PlautmI.IBug-ThisPlau6FDhu/GFDhu (n=28). In the main groups, CNP was created by the bilateral sciatic nerve ligation, with В16/F10 melanoma transplanted under the skin of the back 2 weeks after. The comparison groups included sham operated animals with melanoma transplantation, the control groups – sham operated animals and animals with CNP. Mice were decapitated on day 21 of the tumor growth, and the brain levels of brain neurotrophic factor (BDNF); nerve growth factor (NGF), neurotrophins 3 (NT3) and 4 (NT4) were studied by ELISA.

Results. The brain of mice with uPA gene knockout demonstrated higher levels of NT3 (by 1.3 times (p=0.0146)), NT4 (by 2.6 times) and NGF-β (by 1.9 times (p=0.0021)) and lower BDNF (by 1.7 times (p=0.0203)), compared to mice without knockout. Cerebral reduction of NGF-β was a nonspecific brain response to CNP and neoplastic growth in female mice, enhanced in the combination of the pathological factors. Greater stimulation of subcutaneous melanoma growth in female mice with uPA knockout under the influence of CNP combined with a 2-fold decrease in levels of NT3 and BDNF in the brain, along with 2.2 times higher cerebral levels of NGF-β, compared to female mice without knockout.

Conclusions. In female mice with uPA gene knockout compared to mice without knockout, we revealed background differences and other dynamics of neurotrophin levels in the brain at melanoma growth both alone and in combination with comorbid pathology – CNP.

The article considers the impact of the pandemic on the psychological state of modern boys and girls, in particular, the impact of forced restrictions on the psycho-emotional state and potential suicidal behavior. The results of a diagnostic study of suicidal risks in modern youth in the era of the pandemic are presented. The characteristic of the concepts of suicide and suicidal behavior is given. Studies of suicidal behavior types, factors that can lead to this non-constructive behavior are analyzed. It is noted that impossibility to realie the need for social contacts that is significant for young people can provoke the appearance of a depressive state, which in its extreme manifestations can lead to suicide. The data presented in this article allow us to conclude that the following factors are characteristic boys and girls who have a high level of suicidal risk: high emotionality and inability to control their emotional state, while boys and girls of this group perceive the world in a hostile way. But at the same time they are not able to plan constructively their future, and they have not recorded the presence of restraining factors in the form of a sense of duty to relatives and friends, or fear of death. The opposite results were obtained in the group of boys and girls with an average level of suicide risk. Thus, it can be concluded that modern young people are not adapted to dramatically changing conditions and it is this maladjustment that can provoke suicide, especially in a pandemic situation.

The article analyzes the results of a study of the influence of perfectionism on the emotional burnout of teachers of basic general education. Attention is drawn to the fact that, despite the reforms and modernization in the system of Russian education, the position of the teacher of basic general education remains difficult. In such a situation, it seems necessary to study and identify various factors contributing to the mental fatigue of teachers. The object of the research is perfectionism as a multidimensional construct with a complex structure which includs high personal standards, cognitive and interpersonal parameters. The subject of the research is perfectionism and emotional burnout among teachers of basic general education. The purpose of the work is to study and identify the impact of perfectionism on the emotional burnout of teachers of basic general education. The research hypothesis is high demands directed at oneself and others, comparing oneself with other more successful people, affect the occurrence of symptoms of emotional burnout in teachers. The study involved 120 teachers. We used the techniques of “Questionnaire of emotional burnout” by V. V. Boyko and “Multi-profile scale of perfectionism” MPS-F (R. Frost), methods of mathematical statistics t-Student's test, One-way ANOVA. It was found that teachers had symptoms of emotional burnout, a significantly higher level of perfectionism. The influence of all scales of perfectionism on the phases and symptoms of emotional burnout was revealed. Excessively high personal standards set by teachers affect the triggering of the mechanisms for the formation of emotional burnout, and dissatisfaction with oneself and the profession increases.
