THE SUBSTANTIAL FEATURES OF REPRESENTATIONS OF STUDENTS ABOUT THEMSELVES AS THE SUBJECT OF PROFESSIONAL ACTIVITY

Abstract. The article deals with the characteristics of self-image of a person as the central organizing,integrating and regulatory authority of the psyche, and the main result of ontogenetic human mental development. The authors of the article consider the individual’s image “I am a professional” as an objective indicator of the dynamics of the professional consciousness of an individual. The changes in the person’s content and structure, thoroughly characterize the changes in the attitude of the person to him or herself as the subject of professional activity at all psychological levels. The definitions of self-awareness, self-concept self-evaluation and self-image in professional development are considered. Modern research on the person professional development are made on the basis of the person-activity approach which takes into account the unity of both the operational sphere and the sphere of motives and needs of the educational and professional activity. All the students of the Romano-Germanic Philology Faculty andthe Faculty of Math’s and Physics beginning with the freshmen and ending up with the undergraduate students, took part in the research the article describes. The content features of the changes of the self-image ‘I am a professional’ according to the stage of learning were analyzed.Keywords: Professional self-awareness, self-concept, professional, beginner expert, professionalization,student, subject, personality

Evaluating Business Attractiveness of Cities by Considering the Human Resource Management for Supply Chains in Cities More Than Million Population in Russia

today, cities become centers of entrepreneurial activity and innovation development, the main driving force. Business chooses the territory where there are the best conditions for the development and further successful functioning, as well as guarantees of profit. It can be achieved by the human resource management based on the supply chain strategies. That is why large cities nowadays are becoming competitors for the most successful entrepreneurs. Attracting business directly depends on the effective use of the full potential of the city territory, as well as on designing the effective municipal policy for attracting business, taking into account city’s strengths and weaknesses. In order to evaluate city attractiveness for business in Russia the authors collected a database consisting of a set of indicators over a period of five years (2013-2017). A comprehensive and detailed evaluation of each of the indicators made it possible to identify the strengths and weaknesses of each selected city and compare the data obtained by translating the values into indices. It allows us not to focus on the study of each city in isolation, but to compare them with each other, to reveal competitive advantages. Based on the integral index of business attractiveness, the following groups of Russian cities are distinguished: cities leading for business attractiveness (Yekaterinburg, Krasnoyarsk, Kazan), cities middling for business attractiveness (Ufa, Nizhny Novgorod, Rostov-on-Don, Perm, Novosibirsk, Samara, Chelyabinsk), cities-outsiders for business attractiveness (Voronezh, Volgograd, Omsk)

Accumulation of dehydrin-like proteins in the mitochondria of cereals in response to cold, freezing, drought and ABA treatment

BACKGROUND: Dehydrins are known as Group II late embryogenesis abundant proteins. Their high hydrophilicity and thermostability suggest that they may be structure stabilizers with detergent and chaperone-like properties. They are localised in the nucleus, cytoplasm, and plasma membrane. We have recently found putative dehydrins in the mitochondria of some cereals in response to cold. It is not known whether dehydrin-like proteins accumulate in plant mitochondria in response to stimuli other than cold stress. RESULTS: We have found five putative dehydrins in the mitochondria of winter wheat, rye and maize seedlings. Two of these polypeptides had the same molecular masses in all three species (63 and 52 kD) and were thermostable. Drought, freezing, cold, and exogenous ABA treatment led to higher accumulation of dehydrin-like protein (dlp) 63 kD in the rye and wheat mitochondria. Protein 52 kD was induced by cold adaptation and ABA. Some accumulation of these proteins in the maize mitochondria was found after cold exposition only. The other three proteins appeared to be heat-sensitive and were either slightly induced or not induced at all by all treatments used. CONCLUSIONS: We have found that, not only cold, but also drought, freezing and exogenous ABA treatment result in accumulation of the thermostable dehydrins in plant mitochondria. Most cryotolerant species such as wheat and rye accumulate more heat-stable dehydrins than cryosensitive species such as maize. It has been supposed that their function is to stabilize proteins in the membrane or in the matrix. Heat-sensitive putative dehydrins probably are not involved in the stress reaction and adaptation of plants

Tattoo Removal Methods

Този феномен датира от преди около 5200 години и е значимо внедрен в корените на човешката еволюция.Цел: Да се анализира достъпната литература, реферирана в базите данни MEDLINE (PubMed), Scopus и Web of Science през последните 10 години.Материали и методи: Проучени са съдържанията на резюметата и пълнотекстовите публикации по проблема. Резултати: Основните методи за детатуаж биват: механични, химични, термични, хирургични, смесени методи. Златен стандарт за детатуаж са лазерите с различна модалност на действие.Изводи: Премахването на татуировки се осъществява чрез механични, химични, термични, хирургични и смесени методи. Лазерните технологии дават най-добри клинични резултати по отношение степента на премахване на пигмента и вероятността от възникване на странични ефекти. Различните пигменти за татуаж изискват различна модалност на действие на лазерите. Клиничният резултат от премахването на татуировки е индивидуален и зависи от формата и големината на татуировката, давността, механизма на направа, използвания цвят и плътност на пигмента, имунитета на пациента.Introduction: The art of tattooing is an ancient way of a personal expression. It reflects religious, cultural, social and moral belonging. This phenomenon has been known to humankind for more than 5200 years and it has been profoundly implemented in human evolution.Aim: The aim of this paper is to evaluate the literature in the last 10 years in MEDLINE (PubMed), Scopus and Web of Science – referred literature databases.Materials and Methods: Abstracts and full text publications on the topic were reviewed.Results: The principal methods of tattoo removal are: mechanical, chemical, thermal, surgical and mixed methods. Lasers are the golden standard for tattoo removal.Conclusion: Tattoo removal can be achieved through mechanical, chemical, thermal, surgical and mixed methods. It is established that the laser technology is the most effective method in tattoo removal in regard to both the level of pigment elimination and the percentage of adverse effect manifestations. Different pigments require different modes of laser action. The effectiveness of tattoo removal is strongly individual and depends on the shape and size of the tattoo, duration, method of tattooing, the color and density of the pigment and the host immunity

Sequence comparison of prefrontal cortical brain transcriptome from a tame and an aggressive silver fox (Vulpes vulpes)

<p>Abstract</p> <p>Background</p> <p>Two strains of the silver fox (<it>Vulpes vulpes</it>), with markedly different behavioral phenotypes, have been developed by long-term selection for behavior. Foxes from the tame strain exhibit friendly behavior towards humans, paralleling the sociability of canine puppies, whereas foxes from the aggressive strain are defensive and exhibit aggression to humans. To understand the genetic differences underlying these behavioral phenotypes fox-specific genomic resources are needed.</p> <p>Results</p> <p>cDNA from mRNA from pre-frontal cortex of a tame and an aggressive fox was sequenced using the Roche 454 FLX Titanium platform (> 2.5 million reads & 0.9 Gbase of tame fox sequence; >3.3 million reads & 1.2 Gbase of aggressive fox sequence). Over 80% of the fox reads were assembled into contigs. Mapping fox reads against the fox transcriptome assembly and the dog genome identified over 30,000 high confidence fox-specific SNPs. Fox transcripts for approximately 14,000 genes were identified using SwissProt and the dog RefSeq databases. An at least 2-fold expression difference between the two samples (p < 0.05) was observed for 335 genes, fewer than 3% of the total number of genes identified in the fox transcriptome.</p> <p>Conclusions</p> <p>Transcriptome sequencing significantly expanded genomic resources available for the fox, a species without a sequenced genome. In a very cost efficient manner this yielded a large number of fox-specific SNP markers for genetic studies and provided significant insights into the gene expression profile of the fox pre-frontal cortex; expression differences between the two fox samples; and a catalogue of potentially important gene-specific sequence variants. This result demonstrates the utility of this approach for developing genomic resources in species with limited genomic information.</p

Social stratification of households in the context of the digital divide

To study issues of social deprivation and inequality, scientists explore factors, correlations and various indices and models. The deprivation indices are used in many countries to target interventions and policies to populations with the greatest needs. The aim of this research is to construct stratification scale of Russian households for the period of Covid-19 pandemic to study their social deprivation. The data source for household social deprivation is the Russian Longitudinal Monitoring Survey (RLMS-HSE). The results show that the digital divide of households in extreme poverty greatly increases their social exclusion and increases social deprivation. About 50% of extremely poor households live in rural areas. It confirms the ongoing income stratification of urban and rural residents. About 30% of households do not own a car. In the context of the restrictions of the self-isolation regime, this is a significant factor in social exclusion. Low incomes and material deprivation do not allow such households to change this situation. Even not all rich households have access to high-speed Internet. This may be due to the underdevelopment of high-speed Internet infrastructure

Nanocrystalline Oxides NixCo3−xO4: Sub-ppm H2S Sensing and Humidity Effect

In this work, p-type oxide semiconductors, Co3O4 and complex oxides NixCo3−xO4 (x = 0.04, 0.07, 0.1), were studied as materials for sub-ppm H2S sensing in the temperature range of 90–300 °C in dry and humid air. Nanocrystalline Co3O4 and NixCo3−xO4 (x = 0.04, 0.07, 0.1) were prepared by coprecipitation of cobalt and nickel oxalates from nitrate solutions and further annealing at 300 °C. The surface reactivity of the obtained materials toward H2S both in dry and humid atmosphere (relative humidity at 25 °C R.H. = 60%) was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Sensor measurements showed a decrease in sensor signal toward 1 ppm H2S with an increase in Ni content because of a decrease in chemisorbed surface oxygen species. On the other hand, sensor signal increases for all samples with increasing the relative humidity that depends on reactivity of the surface hydroxyl groups, which stimulate the decomposition of surface sulfites and provide better surface regeneration at higher temperature. This assumption was additionally confirmed by the faster saturation of the conductivity curve and a decrease in the sensor response time in humid air
