Published: December 2023

ABSTRACT Job satisfaction is multifactorial and is directly related to the quality of health services. The main objective of this study was to characterize the level of job satisfaction and the work context of the multidisciplinary teams in specialized rehabilitation services in the state of Alagoas, Brazil. We evaluated the professional profile of participants and sociodemographic information. The Work Context Assessment Scale (WCAS) which is divided into three dimensions and questions adapted from the satisfaction and remuneration dimensions of the Great Place to Work methodology for the Organizational Climate Survey, was used. We included 190 professionals, the mean age was 35.47±9.25 and 86.3% were women. Most participants worked in the capital (60%) and 84.7% had a monthly wage ranging from R$1,000 to R$3,000. The dimension of “work organization” was crucial. The items “pace of work,” “strong demand,” “performance monitoring,” and “repetitive tasks” presented the worst results, but 92.7% are satisfied with their professional activities. The logistic regression analysis showed that more years since graduation and lower scores of Work conditions and Socio-professional relationships were associated with higher job satisfaction. Job satisfaction was found to be high, the dimension of work organization was crucial, and almost half of the participants have already thought about leaving their careers.

Authors: Araujo Cintia Pereira de , Olivo Clarice Rosa
Published: December 2023

RESUMO Na formação dos profissionais de saúde, os professores geralmente vivenciam algumas dificuldades e preocupações. A pandemia de COVID-19 amplificou ainda mais esses desafios, acarretando mudanças nos métodos de ensino e gerando novas preocupações. O objetivo deste estudo foi investigar quais são as preocupações dos professores (PPs) dos cursos de graduação em Fisioterapia com relação ao ambiente de aprendizagem durante a pandemia de COVID-19. Fisioterapeutas que atuavam como docentes em cursos de graduação em Fisioterapia no Brasil foram convidados a responder a um questionário de sobre as PPs (Teacher Concerns Questionnaire - TCQ), sobre perfil sociodemográfico e sobre a percepção de mudanças nas PPs devido à pandemia. Participaram 187 fisioterapeutas professores que apresentaram PP moderada (TCQ: 49,6±10,5), sem associação com a fase da carreira docente, a idade ou o tempo de formação. Aqueles que participam de atividades de formação continuada em docência apresentaram maior PP. Alterações nas PPs decorrentes da pandemia foram relatadas por 94,1% dos participantes. Conclui-se que os professores que participam de atividades de formação continuada se preocupam mais com o impacto de sua prática do que os que não participam. Ao mesmo tempo, essas preocupações parecem ter mudado durante a pandemia.

Flora of Viçosa, Minas Gerais State, Brazil: the ancient fern orders Gleicheniales and Osmundales (Polypodiopsida)
Authors: Miranda Vanessa Maria da Silva , Schwartsburd Pedro Bond
Published: December 2023

ABSTRACT In the Municipality of Viçosa, one family, three genera, and five species of Gleicheniales occur: Dicranopteris flexuosa, Gleichenella pectinata, Sticherus bifidus, S. lanuginosus, and S. nigropaleaceus (Gleicheniaceae). All these species are very common in the area, forming dense thickets (“gleiquenais”) in disturbed areas, and co-occurring in these thickets. Dicranopteris flexuosa, G. pectinata, and S. bifidus are widespread in the Neotropics; Sticherus lanuginosus is widespread in South America and Costa Rica; and S. nigropaleaceous is endemic to the Brazilian Atlantic Forest. We provide nomenclatural corrections for S. lanuginosus. In Osmundales, only one species is found in Viçosa, occurring in marshes: Osmunda palustris (Osmundaceae). The taxonomy of Osmunda is still controversial, with the main Brazilian taxon named as O. palustris, O. regalis, O. regalis subsp. palustris, O. regalis var. spectabilis, O spectabilis, or O. spectabilis var. palustris. In our view, the best name for the taxon occurring in Viçosa is O. palustris, a taxon likely with a Neotropical distribution. Our taxonomic judgment is based on the re-interpretation of recent phylogenetic works, together with populational and morphological studies comparing Brazilian specimens with specimens from the U.S.A. We present descriptions, illustrations, examined specimens, taxonomic comments, and keys to identification.

Published: December 2023

ABSTRACT Speech therapy interventions may be influenced by how one thinks, feels, and talks about death and dying. The literature suggests that the (future) speech therapist should learn how to manage their emotional responses related to death and dying and broaden their perspectives to consider death and dying as part of the human experience through reflective formative strategies and experiential learning, resembling the characteristics of a Death Cafe. This makes its formative use potentially applicable in this context. The Death Cafe is a global social franchise with pre-established rules, where people gather to freely discuss death as a part of life, without predefined objectives or themes, distinguishing it from grief support, lectures, and the like. Studies discuss the benefits of students and healthcare professionals participating in Death Cafe, including transforming death into a naturalistic perspective, exploring the humanity of dying, reassessing how they approach and want to approach end-of-life care, managing emotions, and enhancing clinical judgment.

Published: December 2023

Abstract Adenium obesum belongs to the Apocynaceae family and is characterized as a succulent shrub with a multitude of botanical and morphological features of ornamental interest. The aim of this study was to evaluate the genetic dissimilarity of 28 accessions of A. obesum using morphological descriptors and multivariate techniques with the aim of pre-selecting the genotypes with the greatest ornamental potential. The distribution of the number of flowers throughout the year showed two flowering peaks in January and September. Twenty-one petal pigmentation patterns were identified, and 50% of the accessions had double-petal arrangement. The Gower’s algorithm and the UPGMA-generated dissimilarity matrix indicated the formation of three groups. While Tocher’s clustering method separated the accessions into eight groups showing greater ability to distinguish the evaluated genotypes. In conclusion, the multivariate analyses applied were effective in accessing the genetic diversity among the 28 accessions evaluated. The accessions ICA001, ICA005, ICA006, ICA018, ICA019, and ICA027 were preselected to compose the germplasm collection due to their high ornamental potential.

Abstract The effects of melatonin application by itself and mixed with sucrose solution on vase life and physicochemical changes in amaryllis cut flowers were investigated. Amaryllis stems with flower buds at harvest points were placed into vases containing different maintenance solutions: Melatonin (Mt; 0.01 mM), Sucrose (Suc; 4%), Melatonin + Sucrose (Mt + Suc; 0.01 mM + 4%) and distilled water (Control). Each treatment consisted of five repetitions, with one inflorescence stem per vase. The vases remained at 22 ± 3 °C and constant lighting of 13 µmol m-2 s-1 for 14 days. Immersion of stems in Suc or Mt + Suc delayed the initial senescence processes of the amaryllis cut flower. Vase life was prolonged for additional 2 days compared to stems immersed in water (control), increasing from 10 to 12 days of conservation. Floral stem mass was kept more stable; the degradation of anthocyanin and flavonoid pigments was delayed; and the stability of phenolic compounds and total carbohydrates was maintained for 14 days. These findings confirm the role of melatonin as a preservative in cut flowers. However, its preservative effect was potentialized by the addition of sucrose to the water of the amaryllis cut flowers. More work needs to be carried out to investigate the physiological mechanisms promoted by the interaction of melatonin and sucrose in the regulation of senescence in amaryllis cut flowers, including the analysis of gene expression and activity of the antioxidant system.
ENCARCERAMENTO E EDUCAÇÃO PRISIONAL EM TEMPOS DE NEOLIBERALISMO E CONSERVADORISMO NO BRASIL
Authors: França Rosilene Marques Sobrinho de
Published: December 2023

RESUMO O trabalho objetiva analisar os paradigmas que perpassam a educação prisional, discutindo como eles se apresentam na ordem capitalista neoliberal e conservadora na atualidade. A metodologia compreendeu estudo bibliográfico, tendo como base autores que analisam a implementação dos sistemas educacionais e penitenciários no Brasil, e documental, com exame de documentos produzidos pelo Departamento Penitenciário Nacional, leis e normativas que regulam a oferta da educação prisional. Os resultados mostraram que, apesar de a educação assumir um importante papel no que se refere à garantia de direitos e ao exercício da cidadania, a sua implementação na realidade brasileira tem sido perpassada por uma perspectiva elitista e privatista que reforça as desigualdades socialmente construídas. Considerando as relações verticalizadas e hierarquizadas produzidas com base nas desigualdades de classe, raça/etnia e gênero, o cárcere é utilizado como instrumento de manutenção de poder e de repressão a grupos sociais indesejáveis, cuja base são sistemas de opressão que se articulam com o classismo, o racismo, o patriarcado e o sexismo. Os resultados demonstraram a importância do desenvolvimento de uma educação prisional fundamentada nos pilares da democracia e da cidadania, bem como da efetivação de políticas de desencarceramento, no sentido da construção de uma sociedade livre, justa e mais igualitária.

Published: December 2023

Abstract The objective of this work was to evaluate the effects of 26 days of waterlogging, compared with field capacity, on different traits of the forage plants 'Finecut' Chloris gayana, 'Klein Verde' Panicum coloratum, and 'Shawnee' Panicum virgatum, grown in alkaline-sodic soil. Shoot and root dry mass, leaf greenness index, electrolyte leakage, and root histology were evaluated. The histological analysis was performed along the mid-portion of adventitious roots with a 2.0 mm diameter. Waterlogging inhibited the growth of P. coloratum, in addition to decreasing the leaf greenness index and causing injuries in the cell membrane of C. gayana and P. coloratum. At field capacity, only C. gayana and P. coloratum had aerenchyma; however, waterlogging induced the development and increased the area of the aerenchyma in P. virgatum and C. gayana, respectively. Waterlogging also thickened the exodermis and endodermis of all three genotypes, inducing a greater number of exodermis cell rows and a thicker internal tangential cell wall of the endodermis in C. gayana and P. virgatum. Although P. coloratum growth is more sensitive to waterlogging, there are radial oxygen loss barriers in the roots of the three evaluated genotypes.

Published: December 2023

Abstract The objective of this work was to compare nitrous oxide (N2O) emissions from urine and manure of Nellore and crossbred (Nellore x Angus) cattle finished in feedlot. Twenty Nellore and 20 crossbred bulls were fed a diet consisting of 75% concentrate and 25% roughage. Excreta were applied to the pens after 43 days of confinement, when N2O monitoring started through static chambers. The data were subjected to the analysis of variance, and averages were compared by Tukey’s test. The N2O fluxes from urine and manure were similar among the breeds, with important peaks after rain events. The cumulative emissions of N2O from urine per kilogram of body weight gain (BWG) and the total emissions from manure per kilogram of BWG were 22.7% and 24.4% higher in Nellore cattle. There is no breed effect on N2O flux and cumulative emissions by excreta from confined beef cattle; however, the crossbreed emits less per kilogram of BWG. There is a high correlation between rainfall volume and the N2O emissions of the next day, which indicates a period between rain occurrence and the increase in N2O emission.

Published: December 2023

Abstract The objective of this work was to evaluate the quality of meads prepared with multifloral honey, unifloral orange blossom honey, and a mixture of both. To prepare the meads, multifloral honey and orange blossom honey from Southern and Southeastern Brazil, respectively, were used. The physicochemical properties, total phenolic content, and antioxidant capacity of the meads were determined. The phenolic compounds were identified by mass spectrometry, and sensory tests were carried out. Multifloral honey showed higher levels of ash content, reducing sugars, and total phenolic compounds than orange blossom honey. The multifloral and mixed meads presented the highest levels of total phenolics, total polyphenol index, and antioxidant capacity. The orange blossom mead showed the highest scores in the sensory analysis for color, aroma, flavor, and global acceptance. The phenolic compounds identified in the meads were the chlorogenic, protocatechuic, syringic, and p-coumaric acids, as well as naringenin and quercetin. The physicochemical, functional, and sensory characteristics of the meads are affected by the honey used in their preparation.

Published: December 2023

Abstract The objective of this work was to evaluate the effect of silicon (Si) on the cultivation and quality of raspberries (Rubus idaeus). The experiment consisted of seven treatments and four blocks located in a subtropical region. Each plot consisted of three pots with one seedling of 'Batum' raspberry. In each pot, the treatment consisted of Si doses at 0, 50, 100, 200, 400, 800, or 1600 mg dm-3, which were applied to the soil 15 days after the transplanting of the seedlings. Field analyses were performed by measuring chlorophyll a and b, water potential, and production. Fruit were analyzed for color, firmness, respiratory rate, soluble solids, and pH. Fertilization with Si stimulates the increase of fruit number and of the raspberry production per plant. The Si application increases the fruit production and fruit firmness; however, it reduces the water potential and respiration rate.

Abstract The objective of this work was to evaluate packaging for preserving the quality of soybean (Glycine max) seeds stored in different environments. The experiment design was completely randomized, in a factorial arrangment with six seed storage conditions: natural atmosphere (NA), laminated packaging atmosphere (LPA), modified atmosphere in polyethylene packaging (MAPP), refrigerated atmosphere in raffia packaging (RARP), refrigerated atmosphere in laminated packaging (RALP), and modified and refrigerated atmosphere in polyethylene packaging (MRAPP), with four storage times (zero, two, four, and six months). Storage time reduces the quality of soybean seeds after two months in all tested packaging. The germination of the soybean seeds was maintained in the following packaging: LPA, RARP, RALP, and MRAPP. LPA is the most efficient packaging for soybean seeds, which show the highest percentage of germination for the longest storage time, without requiring any modification or refrigeration of the atmospheric storage environment.

Published: December 2023

Abstract The objective of this work was to determine the base temperature of six lisianthus cultivars, grown at seven planting seasons in the municipality of Capão do Leão, in the state of Rio Grande do Sul, Brazil. The following cultivars were evaluated: DBL Echo Blue, Robella 2 Pink, Excalibur White, Excalibur 2 Blue Picotee, DBL Echo Champagne, and Arena III Red. Base temperature was determined from the air temperature data collected daily, in each planting season, fusing the lowest variability and development ratio methods. The base temperature for lisianthus cultivars is between 14.0 and 15.0ºC, by the lowest variability method, and between 13.9 and 15.0ºC by the development ratio method. The highest thermal accumulation was obseerved in the second planting season (from 11/23/2017 to 02/22/2018) for all cultivars, and lower air temperatures during the growing season resulted in longer production cycles. In the seven planting seasons, the highest base temperature is 15.0ºC, obtained for cultivar Arena III Red, and the is 14°C, for all lisianthus cultivars.
DETAILED DESIGN AND ANALYSIS FOR ADDITIVE MANUFACTURING OF TOPOLOGICALLY OPTIMIZED AND GENERATIVELY DESIGNED TI-6AL-4V HIP JOINT IMPLANT
Authors: Kishor Abhishek , Burela Ramesh Gupta , Gupta Ankit
Published: December 2023

In this paper, a comprehensive investigation of the design and analysis of Ti-6Al-4V hip joint implants using generative design and topology optimization, along with laser powder bed fusion (LPBF), an additive manufacturing technique, has been presented. The study employed the NSGA-II genetic algorithm for generative design, enabling the generation of diverse optimized designs and topology optimization with the solid isotropic material penalization approach, efficiently reducing implant mass of the design space by up to 75% while maintaining structural integrity. Finite element analysis revealed comparable von Mises stress and deformation levels between geometries obtained with generative design and topology optimization. However, the combined approach exhibited superior performance, namely, topology optimization followed by generative design, with a 40% reduction in deformation and a 15% reduction in von Mises stress compared to conventional models. LPBF simulations demonstrated the superiority of the optimized geometries, with a 30% reduction in thermal stress and a 66% reduction in deformation compared to conventional designs. It is observed that design input for generative design significantly impacts the output design. Also, geometry has a notable impact on the quality of the printed part.
Influence of high temperatures on modes I and II fracture toughness and energy of nanoclay-reinforced polymer concrete
Authors: Aghdam Ali Abdi , Hassani Niaki Mostafa
Published: December 2023

This paper investigates the influence of exposure to elevated temperatures on the fracture mechanics of polymer concrete (PC). The PC was synthesised using epoxy, silica sand, crushed basalt, and nanoclay. The prepared PC was exposed to temperatures of 24, 40, 60, 80, 100, 120 and 140°C for two hours, and the residual fracture toughness and fracture energy in mode I and mode II were studied. The three-point bending test was conducted on cracked semi-circular bend specimens with a crack angle of 0° (pure mode I) and 41° (pure mode II) to determine the fracture parameters. Subjection to high temperatures significantly increased the fracture toughness and fracture energy of the PC. The maximum fracture toughness and fracture energy were obtained after exposure to temperatures of 120°C and 140°C, respectively. Scanning electron microscopy was used to investigate the fracture surface of the PC. The type of fracture (brittle or ductile) of the PC before and after exposure to the target temperatures was evaluated. The mathematical relationships between modes I and II critical stress intensity factor (KIc and KIIc), as well as modes I and II fracture energy (GIf and GIIf) after exposure to high temperatures, were also determined.

Significance Statement

In CKD, metabolic acidosis is commonly treated with alkali in the hope that it will improve bone health. In a post hoc analysis of the Bicarbonate Administration to Stabilize eGFR Pilot Trial, we investigated whether sodium bicarbonate affects serum levels of bone turnover markers and other hormones related to bone health in individuals with CKD who have normal to slightly reduced total CO2 (20–28 mEq/L). Sodium bicarbonate increased serum levels of α-klotho but had no significant effect on other bone health markers, including intact fibroblast growth factor-23 (iFGF-23), intact parathyroid hormone (iPTH), and bone-specific alkaline phosphatase (B-SAP). Further study is needed to determine the effect of bicarbonate administration on clinical aspects of bone health.

Background

Treatment with alkali has been hypothesized to improve bone health in CKD by mitigating adverse effects of acid on bone mineral. We investigated the effect of treatment with sodium bicarbonate on bone turnover markers and other factors related to bone metabolism in CKD.

Methods

This is a post hoc analysis of the Bicarbonate Administration to Stabilize eGFR Pilot Trial in which 194 individuals with CKD and serum total CO2 20–28 mEq/L were randomly assigned to placebo or one of two doses of sodium bicarbonate (0.5 or 0.8 mEq/kg lean body weight per day) for 28 weeks. The following serum measurements were performed at baseline, week 12, and week 28: B-SAP, c-telopeptide, procollagen type I intact N-terminal propeptide, iPTH, iFGF-23, soluble klotho, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, and tartrate-resistant acid phosphatase 5b. The difference (sodium bicarbonate versus placebo) in mean change of each bone biomarker from baseline was determined using linear mixed models.

Results

One hundred sixty-eight participants submitted samples for post hoc investigations. Mean eGFR was 37±10 ml/min per 1.73 m2 and mean total CO2 was 24±3 mEq/L at baseline. Sodium bicarbonate induced a dose-dependent increase in soluble klotho levels compared with placebo. There was no significant effect of treatment with either dose of sodium bicarbonate on any of the other bone biomarkers, including iFGF-23, iPTH, and B-SAP. Effects on bone biomarkers were similar in those with baseline serum total CO2 <24 mEq/L compared with those with total CO2 ≥24 mEq/L.

Conclusions

Background: Polyherbal decoctions are frequently utilized by some Africans for anti-malaria treatment because they are readily accessible, and assumed low toxicity despite possible gonadotoxicities. We investigated ameliorative potential of anti-plasmodial plants Azadirachta indica (AI) and Gongronema latifolium (GL) on Plasmodium-induced gonadotoxities. Materials and methods: Adult male Swiss mice (n = 50) were allotted into 10 groups of (n = 5) animals. All groups were parasitized with 1 × 106P. berghei inoculum for three days except for groups 1 and 10; (normal control [NC]) and (non-parasitized mice administered Arthemeter-Lumefantrine [AL]). Group 2 was parasitized non-treated (PNT), groups 3 and 4 received low and high doses AI (86.60 and 259.81 mg), groups 5 and 6 received low and high doses GL (337.27 and 1011.80 mg), Groups 7, and 8 received low doses AI + GL (86.60 + 337.27 mg), and high doses AI + GL (259.81 + 1011.80 mg), while Group 9 received AL (8 mg), all odes via oral gavage per kg body weights, respectively. Rectal temperature, seminal/hormonal, testicular morphometry and histology assessments were evaluated using standard protocols. Results: Concurrent administration of AI and GL alleviated pyrexia and parasitemia in test groups, compared to NC and PNT groups. Testosterone concentrations were reduced in parasitized groups compared to NC, while sperm parameters significantly decreased (p < 0.05) in PNT and high AI + GL extract groups, but improved in combined low dose with testicular histoarchitecture. Conclusions: AI and GL concurrently administered at low doses mitigate P. berghei-induced gonadotoxicity better than as singly.

Odore di Napoli: Normativity from Objects and Smells
Authors: Branco Patrícia , Mohr Richard
Published: December 2023

Observing the differences between insiders' and outsiders' perceptions of the smells of Naples, we draw parallels with different views of law. Insiders relate to the smells of the city as a complex olfactory web that defines places and regulates time. Outsiders generally privilege the sense of sight over smell. The groups relate differently to the urban fabric of the city, including the tangible walls and streets, and the intangible smells and the ephemeral meals. Such differences are here mediated by material objects, from cameras or phones to garbage and cruise ships, from Mount Vesuvius to the Tyrrhenian Sea. Legal outsiders observe regularities in behaviour which indicate the presence of laws. On the other hand, law is also seen as a set of rules to which one must. Rules and regularities seem inadequate to understand the complex ways Neapolitans negotiate their olfactory and legal environment. Informal legal normativity is inscribed in the walls and the geography, and mediated by the food and the smells of their city, that make up their own smellscapes, juxtaposing the scents and the stinks, profumo and puzza, and their ways of regulating behaviour, in time and space.
THE CONCEPT AND ONTOLOGY OF ADMINISTRATIVE REFORM
Authors:   Institute of Public Administration and Civil Service of the Russian Presidential Academy of National Economy and Public Administration, Ponkin I. V.
Published: December 2023

Abstract: the article is devoted to the theoretical comprehension and representation of the administrative reform. According to the author's approach, administrative reform is a permanent and multifaceted integral element of the public administration ontology. The author explains the reasons for activating the administrative reform. The article reveals the concept of design of the public administration system. The author explains the functional-target load of the administrative reform, its heterogeneity in relation to time. The article presents detailed descriptions of the main directions of the administrative reform. The author provides visualizing models of the meta-process of administrative reform, including a schematic representation of the “hilly landscape” visually displaying the meta-process of administrative reform. According to the author's concept, such representations of administrative reform are needed to create digital twin models that allow for preventive testing and testing of certain designed solutions and measures of administrative reform, in one direction or another of its implementation.

Authors:   Perm Financial and Economic College – Branch of the Financial University under the Government of the Russian Federation, Khakimova Yu. A.
Published: December 2023

Abstract: The article covers the differentiation of gaps in the institution of insurance and estimative concepts of insurance law. The article studies fundamentals of the estimative concepts civil theory, specific estimative concepts of insurance law (in particular, "illegal interests", "substantial change in circumstances", "increase of insurance risk", etc.), as well as the criteria for distinguishing gaps from the evaluative concepts of insurance law. Special attention is given to the provisions of the Concept of Development of Provisions of Part two of the Russian Federation Civil Code related to the insurance contract. It is concluded that the evaluative concepts and gaps of the institution of insurance are not identical due to significant differences between them. The following criteria of differentiation are proposed in the article: the essence of legal uncertainty; the type of legal uncertainty; the mechanism of compensating and overcoming; the functional role in the legal implementation mechanism; the necessity to eliminate.
ACTUAL QUESTIONS OF THE IMPLEMENTATION OF THE CONSTITUTIONAL LEGAL PERSONALITY OF MUNICIPALITIES
Authors:   Penza State University, Zernov I. V.
Published: December 2023

Abstract: the article examines the grounds for the implementation of the constitutional legal personality of municipalities in the Russian Federation. The article analyzes the impact of constitutional legislation on the activities of local self-government bodies. The article considers some materials of constitutional judicial practice, which substantiate the construction of a unified system of public power. The article examines the grounds for the emergence and termination of the constitutional legal personality of municipalities. The possibility of applying the V. E. Chirkin’s concept is indicated on public legal entities in the study of the status of municipalities. The author comes to the conclusion that municipalities by their nature are full-fledged subjects of constitutional relations, which realize their legal personality in the person of local self-government bodies, the head of the municipality, municipal employees, as well as legal entities. Along with the exercise by public authorities of their functions and powers, the legal personality of municipalities is expressed in the possibility of bearing constitutional responsibility.
Social and economic system of regional entrepreneurship as the object of strategizing
Authors: Korchagina I. V. , Pytchenko K. V.
Published: December 2023

To realize the potential of regional entrepreneurship as a system of small and medium-sized enterprises (SMEs) of the region it is essential to develop a successful winning strategy oriented towards rapid exploitation of new opportunities. To this end, it is necessary to clarify the essence, boundaries, structure, and functions of the object of strategizing. The research is based on the general theory of strategy and methodology of strategizing, the theories of entrepreneurship, the systematic approach. The authors study approaches and theories that explain the essence, the functions and the structure of the system of regional entrepreneurship by applying systematization and content analysis methods. While analyzing the theories of entrepreneurship four components of the strategic mission of SMEs have been defined as follows: providing guarantees to partners, movement and productive use of factors of production, implementation of innovation, creation of gazelle companies (with the average annual increase in revenue or employment of more than 20% over 3 years). The study has shown that they are not fully implemented, and so the situation requires developing a new strategy or improving the old one. And the strategy of development of entrepreneurship in the region should contribute to the implementation of higher-level strategies (regional and sectoral). Moreover, the strategy should define the basic policies for strategizing the components of regional entrepreneurship – individual enterprises, clusters, different types of activities. The study offers a structural and logical scheme of relationship of the strategy of development of regional entrepreneurship (on the example of Kemerovo region – Kuzbass) with other strategic planning documents. Also, the authors justify the expediency of differentiation of  strategic priorities of traditional and innovative entrepreneurship in the region. The analysis of theoretical foundations of exploring entrepreneurship as the object of strategizing has made it possible to clarify the basic components of its mission and justify the place of the corresponding strategy in the general system of strategic planning documents. Clarification of the boundaries and the content of the system under study ensures moving on to the strategic OTSW-analysis. The findings of the study can be used in justification of strategic decisions of entrepreneurs and regional authorities.
