The following biological and pharmaceutical factors influence the therapeutic efficacy and bioequivalence of drugs: physicochemical properties of a pharmaceutical substance, bioavailability, type of dosage form, route of administration, nature of excipients, their compatibility, as well as technological conditions of production, including the preparation of drugs forms. Before mass production of a drug, the technological parameters and characteristics of the pharmaceutical substance must be carefully studied and scientifically substantiated. This work is devoted to the study of the technological properties of an original pharmaceutical substance based on the derivative of 3.7-diazabicyclo[3.3.1]nonane with the chemical name IUPAC 6-[4methoxy-3- (1H-pyrazol-1-ylmethyl) benzyl] -1,11dimethyl-3,6,9-triazatricyclo[7.3.1.1]tetradecane-4,8,12-trion, used as an active substance for the development of the composition and technology for the preparation of oral dosage forms in capsule form. The article presents the results of the development and testing of a drug in the form of capsules of the original pharmaceutical substance of the nootropic action of 3,7-diazabicyclo[3.3.1]nonanane, which is practically insoluble in water. The study identified and evaluated the technological and biological properties of a pharmaceutical substance that can affect the pharmacological activity in the production of a dosage form. The study examined the key indicators: solubility, particle size, flowability, bulk density. The technological characteristics of the pharmaceutical substance are studied not only by certain values of the indicated characteristics but also by the values of the Hausner and Carr indices. The data obtained suggest the content and progress of further stages of pharmaceutical development. The presence of the lag phase when dissolving hypromellose capsules in a medium with a pH of 1,2 and relatively low disintegration rates in media with a pH of 1,2, pH 4,5, and pH 6,8 served as the basis for the choice of gelatin capsules. The developed dosage form meets modern pharmacopoeial requirements, including the dissolution kinetics: according to the results obtained, in 45 minutes (77,6 ± 2,5)% of the substance passes into the dissolution medium with a pH of 4,5. The results of the study are used to develop a technological scheme for obtaining the dosage form of 3,7-diazabicyclo[3.3.1]nonane, its indicators, and quality standards.

Published: August 2021

Currently, most oil fields are under the late stage of development, which is associated with some challenges during the production of reservoir products, including the formation of asphalt-resin-paraffin deposits (ARPD) in the “well – bottom-hole formation zone” system. Even though the problem of organic deposits creation has existed for more than 60 years, it is still relevant today. Currently, to prevent the formation of ARPD, inhibitors divided into methods based on the use of wetting agents, modifiers, depressors, and dispersants are widely used infield practice. The composition of inhibitors often includes surfactants, and according to field experience, nonionic surfactants, namely, polyesters, are widely used to prevent the formation of ARPD. However, little is known about inhibitors with a combined effect, for example, possessing depressor-dispersing properties concerning ARPD. Proceeding from the above, the work is aimed to develop a combined inhibitor with depressor-dispersing properties to prevent the formation of ARPD. The dispersing property of the prepared reagent for asphaltene particles was determined using capillary and photocolorimetric methods. The studies were conducted to assess the impact of the reagent on the freezing point. A quantitative assessment of the sedimentation process using the “Cold rod” installation was performed, and the results of studies of the developed ARPD reagent-inhibitor corrosion resistance were presented. Two methods determined the temperature of oil saturation with paraffin: the direct approach – visual observation (Axio Lab A1 microscope) and the indirect approach – rheogoniometry to determine the kinematic viscosity of oil (HVM-472 viscosity analyzer (Walter Herzog GmbH, Germany)). Thus, an ARPD inhibitor (IN-1), comprising a copolymer of ethylene with α-olefins or polymers of acrylic, methacrylic, or cyanoacrylic acid esters, an emulsifier of inverted oil-in-water emulsions and a solvent, was developed. The developed inhibitor, having depressor-dispersing properties, is capable of reducing oil-freezing point in winter and of slowing down the precipitation of paraffin crystals in well equipped and in the bottom-hole formation zone (BHFZ).

Published: August 2021

The efficiency and quality of drilling and blasting operations in the development of mineral deposits largely depend on the variability of the properties of the rock mass. With a detailed study of various geological objectsmineral deposits or structural elements of the earth’s crust of any order, up to a single layer or block, it is possible to create three-dimensional digital models. The article considers the possibility of spatial variability of rock mass properties in Central Kazakhstan by means of mathematical modeling using data from the drilling process control file of the Aquila system of a DH-M drilling rig. To assess the structure and condition of the rock mass, it was constructed two-dimensional sections digital model, which shows the spatial variability of physical and mechanical properties. A pseudolinear approximation between the file vectors is chosen as a method for constructing twodimensional sections. The application of the mathematical method of pseudo-linear interpolation is shown, which allows with a sufficient degree of reliability to evaluate the physical and mechanical properties (PMP) of the rocks in the inter-well and inter-interval space of the rock mass. Based on the results of the study, the software was developed that provides an operational and effective assessment of the physical and mechanical properties of the rock mass with the visualization of the result. The developed approach and software can be used to improve the efficiency of drilling and blasting operations of existing mining enterprises, as well as in the implementation of scientific and industrial research on mathematical modeling of state of the rock mass.

The series complex formation nickel(II) or cobalt(III) with hexafluoroacetylacetone, pyrazole, 3,5-dimethylpyrazole, and 3,5-bis(trifluoromethyl)-1H-pyrazole were prepared. The first reaction step included the synthesis of the complex using hexafluoroacetylacetone as a ligand with Co(III) or Ni(II), metals with high spin with π donate and enol-form of the ligand. This formed complex was identified by FT-IR, 1H-NMR spectroscopy, and magnetic susceptibility calculation. Whereas, the second reaction step to produce the complex depended upon mixing water and pyrazole and using it as ligands with Co(III) or Ni(II) a metal, which is a high spin with one donate and the another is aromatic nitrogen atom in a ligand. In the third reaction step, the complexes were produced by mixing water with 3,5-bis(trifluoromethyl)-1H-pyrazole as a ligand with Co(III) or Ni(II) as low spin metal. The analysis of these prepared complexes and their used ligands were done by comparing the results using 1H-NMR and FT-IR spectroscopies. Besides, the magnetic susceptibility calculation was also employed. The results of 1H-NMR spectroscopy and magnetic susceptibility proved that the produced complexes are diamagnetic when the ligand includes the CF3 group. At the same time, the produced complexes are paramagnetic, when the ligand without the CF3 group, which is formed the mixture of water and 3,5-dimethylpyrazole as ligand or water and pyrazole as a ligand with Co(III) or Ni(II) as metal. All the ligands in the paramagnetic complexes were one donate, and another the donated atom in pyrazol is an aromatic nitrogen atom. Therefore all prepared high spin complexes were not evident in the 1H-NMR spectrum because the peaks appear brood that due to high T1 relaxation 1H-NMR time, and the investigation turned out two assignment peaks. This behavior is an attitude to happen the ketone form and enol form phenomenon by using 1H-NMR spectra, and its an evident assignment coupling between hydrogen or carbon atom with a fluorine atom.

Published: August 2021

Presently, three-dimensional printing technology is developing rapidly. This happens due to the need to create products of complex shape, the production of which by existing standard methods is very difficult and disadvantageous, and sometimes technically impossible. The study aims to investigate the problem of temperature stability of a thin-walled cylindrical structure under unsteady local thermal exposure, simulating the motion of a laser beam spot along one of the ends. To solve the problem, the finite element method was used. Since the geometric areas of calculation were parameterized, then for each set of parameters, its own finite element mesh was used for each type of analysis. A parametric spatial finite element model of cylindrical shell pinched at the bottom end was constructed. The local moving heat flux acts on the opposite side, simulating the movement of a laser beam during the additive formation of a thin-walled element. Numerical solutions of the nonstationary
dynamic heat conduction problem were obtained, spatiotemporal temperature dependences were obtained, and solutions of the quasistatic problem of the loss of both local and complete loss of stability of the equilibrium state of the cylinder at various times due to the occurrence of local compressive stresses during intense heating were obtained. The dependences of critical heat flux power corresponding to the loss of stability on the cylinder wall thickness and its height were obtained. The above results can be used as calibration parameters of the process of creating thin-walled structures using additive technologies of Laser Melting class for products that require increased requirements for manufacturing accuracy.

Published: August 2021

Ce travail porte sur l’évaluation du potentiel des images multi-temporelles et multi-capteurs (optique et radar) des satellites Sentinel 1 et 2 pour la cartographie de l’occupation du sol et le suivi de l’évolution du trait de côte dans un écosystème tropical sur la période 2015 à 2020. La zone d’étude choisie est l’Estuaire du Cameroun. Cette zone représente un milieu de transition écologique majeur dans la sous-région avec la présence de réserves naturelles protégées (mangroves, forêt dense, zones humides) mais aussi une forte activité anthropique (constructions, agriculture, forêt dégradée). L’approche méthodologique a consisté en une chaine de prétraitements et d’analyses visuelles d’images, suivie d’une combinaison des bandes de chaque capteur, d’une classification supervisée Random Forest pour ébaucher une cartographie de l’occupation du sol et enfin une numérisation du trait de côte.  Globalement, les résultats montrent que la classification, avec les images Sentinel 2 en utilisant 10 bandes et en ajoutant 4 indices de végétation, s’avère légèrement plus précise (95.75%) que celle issue des 13 bandes initiales (91.78%). La classification avec les seules images Sentinel 1A double polarisation (VV, VH) conduit à une précision de 78.44%. La combinaison des bandes Sentinel 2A (10 bandes et 4 indices) et Sentinel 1 améliore les résultats et conduit à une précision de  98.76%. Nos résultats montrent aussi que l’utilisation des séries chronologiques d’images multi-temporelles améliore considérablement la précision de classification par rapport à l’usage d’une seule image (mono-date), et cela pour les deux capteurs, soit un gain supplémentaire de 13% et 10% respectivement pour Sentinel-2 et Sentinel-1. Néanmoins ce gain reste faible pour les classes temporellement stables. Les résultats d’analyse de l’évolution du trait de côte montrent que  l’estuaire du Cameroun est perturbé selon différents niveaux d’érosion (Cap Cameroun, Partie Nord île Manoka, embouchure de la Sanaga), et d’accrétion (Limbé, et Partie Sud île Manoka) et aussi par  de faible variations  internes. La fusion des données de télédétection optique et radar dans la discrimination des classes d’occupation du sol, a permis de montrer que les zones de constructions sont les plus vulnérables à l’érosion côtière. Par contre,  la présence de la végétation (mangrove, forêt) stabilise et protège la côte d’éventuels risques de cette nature.

Published: August 2021

Currently waste incineration is a widely used method of waste management in China. Effective incineration requires understanding and tools to analyze the incineration process leading to good incinerator performance and efficiency as well as lower emissions. In this work, a Chinese circulating
fluidized bed (CFB) incinerator firing municipal solid waste (MSW) and coal is modeled with a three-dimensional CFB furnace model to evaluate the incineration process. First, the modeling results are verified with measurement data from the incinerator. Then, the furnace model is applied in
the simulation of a case with more dry MSW without coal. The objective of the research is to provide insight and increase understanding of the MSW incineration process. The simulation case of MSW with the lower moisture content highlights the possible reductions of fossil carbon emissions
associated with the utilization of coal. To achieve this, a moderate reduction in the moisture content of MSW is required. A comparison between the MSW and coal versus only the MSW shows minor differences in the performance of the incinerator. Utilization of modeling in incinerator studies
can aid in development of more efficient CFB incinerators, improving the waste management and reducing the utilization of fossil coal.

Published: August 2021

Spożywanie alkoholu w trakcie ciąży jest zjawiskiem wysoce niepożądanym, często powodującym poronienia lub wiele nieprawidłowości rozwojowych dziecka. Spektrum Płodowych Zaburzeń Alkoholowych, tzw. FASD (ang. Fetal Alcohol Spectrum Disorder) określa zaburzenia fizyczne i psychiczne wynikające z wpływu alkoholu na zdrowie oraz zaburzenia behawioralne dziecka, które zazwyczaj są wtórne do zmian zachodzących w ośrodkowym układzie nerwowym, wywołanych alkoholowym zatruciem płodu w trakcie ciąży. Zmiany te są zazwyczaj nieodwracalne i uwidaczniają się w trakcie całego życia dziecka dotkniętego FASD, ale dzięki odpowiednim terapiom istnieje możliwość zminimalizowania objawów tych zaburzeń. Ich charakter i ciężkość zależą od kilku czynników, między innymi od czasu ekspozycji na alkohol oraz stanu zdrowia kobiety ciężarnej. Wśród klinicznych cech FASD wyróżnia się anomalie w obrębie twarzoczaszki, zaburzenia ośrodkowego układu nerwowego oraz opóźnienie wzrostu. Zmiany strukturalne indukowane alkoholem obejmują anomalie w układzie sercowo-naczyniowym, szkieletowym, nerkowo-moczowodowym, a także w narządach wzroku i słuchu. Ważną rolę odgrywa czas postawienia wstępnej diagnozy, bowiem umożliwia on wprowadzenie odpowiedniej terapii dla dziecka z FASD oraz wprowadzenie odpowiedniej edukacji rodziców i rodziny chorego dziecka. Istnieje możliwość zminimalizowania objawów i zaburzeń wynikających ze Spektrum Płodowych Zaburzeń Alkoholowych, do stopnia umożliwiającego prawidłowe funkcjonowanie dziecka i jego rodziny.

Published: August 2021

Objectives: To assess the pattern of sleep and the correlation with socio demographic parameters in patients with depressive disorder. Study Design: Descriptive cross sectional study. Study Setting and Duration: A psychiatric consultation clinic in Karachi from January 2015 till December 2019. Methodology: Patients between ages of 18 and 60 years, irrespective of gender were included in the study. Patients with florid psychotic symptoms, dementia and chronic debilitating medical illness such as chronic renal or liver failure were excluded. Pattern of sleep was categorized as patients with normal sleep (sound sleep of 7-9 hours), insomnia and hypersomnia. Diagnosis of Insomnia and hypersomnia was made according to ICD – criteria. Results: The mean age of patients was 30.89 (10.256) years. Age was significantly associated with the pattern of sleep among depressed patients. Younger patients between the ages of 18-35 years more frequently suffered from insomnia while the older patients (35-65 years) were more frequently experiencing hypersomnia (p=0.01). The majority of the patients who were either separated or divorced experienced hypersomnia, 15 (71.4%) however, the difference was not statistically significant (p=0.582). The most common psychiatric comorbidity among patients was obsession compulsion disorder (OCD) with a frequency of 225 (39.4%) followed by anxiety disorders; 100 (17.5%). Conclusion: Our study indicates that sleep patterns are significantly challenged in depression patients. The younger population was more prone towards insomnia while the older patients more frequently had hypersomnia. Further large scale studies are needed to explore the risk factors associated with the sleep disturbance and the role normal sleep patterns play in recovery of depressed patients.

Considerando a importância do setor aéreo à economia brasileira e o pedido de recuperação judicial da empresa Avianca Brasil, surge a necessidade de aplicar modelos de previsão de insolvência nas demais empresas representativas do setor. Assim, com o objetivo de analisar os resultados da aplicação de modelos de previsão de insolvência nas principais companhias aéreas brasileiras (Latam, Gol, Azul, Avianca), no período de 2014 a 2018, desenvolveu-se esta pesquisa, caracterizada como qualitativa, descritiva, bibliográfica e documental, utilizando modelos de previsão de insolvência destacados na literatura (Elisabetsky, 1976; Matias, 1976; Kanitz, 1978; Altman, Baidya & Dias, 1979; Silva, 1982; Sanvicente & Minardi, 2000). Os resultados demonstram que a situação de insolvência é identificada nos modelos aplicados às companhias aéreas, em pelo menos um dos períodos, evidenciando possíveis dificuldades para continuidade dos negócios. Latam é a companhia que apresenta os resultados de insolvência menos desfavoráveis, enquanto os resultados da Avianca justificam seu pedido de recuperação judicial. Conclui-se que as companhias aéreas analisadas devem rever suas políticas de gastos, visando melhorar seus desempenhos operacionais. A pesquisa contribui à área contábil no sentido de demonstrar que os resultados da aplicação dos modelos de previsão de insolvência refletem as decisões dos gestores, servindo como ferramenta de gestão financeira e estratégica.

O objetivo deste estudo foi verificar a influência do efeito sunk cost nas decisões, gerenciais e pessoais, tomadas pelos discentes do Curso de Ciências Contábeis das Instituições de Ensino Superior. A pesquisa caracterizou-se como descritiva e de levantamento com abordagem quantitativa. Foram aplicados questionários a discentes de cinco Instituições de Ensino Superior que possuíam o curso Ciências Contábeis, na modalidade presencial. A coleta de dados, realizada nos meses de outubro e novembro de 2019, foi realizada fazendo uso de um questionário, adaptado do modelo de Domingos (2007), Rover et al. (2009) e Segantini et al. (2011) e, quanto aos dados levantados, utilizou-se a análise descritiva das respostas dos participantes e também se empregou o teste estatístico do qui-quadrado (χ2) para testar a significância entre as respostas obtidas. Os resultados encontrados evidenciaram que o valor do custo irrecuperável pode influenciar na ocorrência do efeito sunk costs. Isto pode ser constatado, pois à medida que diminuía o montante do custo perdido, menor era a disposição dos discentes em prosseguir investindo nos cursos de ação que deveriam ser abandonados. Quando a decisão é voltada para o contexto pessoal, os discentes levaram em consideração a premissa de aversão ao desperdício e senso de responsabilidade.

On the Association between Academic Studies and Professional Training – The Case of School Counseling Do Academic Studies Train School Counselors for Their Work, as Perceived by Them Retrospectively?
Authors: Heled Einat , Davidovitch Nitza
Published: August 2021

In the current study we sought to examine how school counselors in Israel, who work in profession for several years, evaluate the association between academic studies and the professional training they received during their Maters’s degree in school counseling. Fifteen school counselors were interviewed regarding their Academic courses, Practical training, enjoyment of one’s studies, what is missing in the training process and their experience of entering the role after the academic studies. Retrospectively, the research findings showed that the academic program was not compatible with practical training for the counselor’s actual work, as perceived by the school counselors. The results also showed that many changes must be made in Master’s degree programs to better train school counselors for their job. The findings of the current study reinforce the inconsistent and vague definition of the school counselor’s job and accentuate the many years of academic training that is not adapted to the school counselor’s role.

A educação em direitos humanos no currículo escolar do município de Santo André
Authors: Garrrido Marina Aparecida , Garcia Paulo Sérgio
Published: August 2021

Este estudo analisou as diretrizes relacionadas à Educação em Direitos Humanos (EDH), voltadas para o Ensino Fundamental, presentes nos documentos curriculares do município de Santo André –São Paulo. Foi utilizada a abordagem qualitativa, a partir da análise de conteúdo. Os resultados mostraram que em que pese a presença de algumas diretrizes particularizadas, há um quadro visível de ausências de indicações que pode obstaculizar a formação dos alunos em relação à EDH. Neste contexto, as escolas podem ter concepções, ideias e projetos muito diversos para trabalhar o assunto ou, simplesmente, colocá-lo em um segundo plano. Tal processo pode dar origem a oportunidades de aprendizagem, em relação EDH, muito diferentes. De fato, enquanto alguns jovens poderão vivenciar uma cultura de tolerância, de paz, de solidariedade e de respeito aos direitos humanos, outros podem ficar com este direito restrito. Um processo que pode ser caracterizado como discriminação social. estes dados podem ser usados para fomentar as discussões do a EDH.

Authors: Santos Enise Aragão dos , Torkomian Ana Lúcia Vitale
Published: August 2021

Objective of the study: Investigate what are the individual characteristics of the digital entrepreneur in startups.Methodology/approach: a multiple case study was carried out with five startups incubated in a digital hub, using participatory observation, transcription of public information and semi-structured interviews with the leading entrepreneurs of each company as sources of evidence. The interviews were coded and analyzed based on the content analysis technique.Originality/Relevance: Given the upward movement of digital entrepreneurship, which needs to be seen as an entirely new field of research due to the unique characteristics of the Internet, a prominent theme that needs to be investigated is the relationship between entrepreneurship and the adoption of digital platforms for creating startups in validation processes.Main results: It was found that the main characteristics of digital entrepreneurs are related to gender, age, academic background, professional experience, and personal knowledge and skills in the chosen sector, pointing out that they can, at least so far, facilitate the success of the digital platform.Theoretical/methodological contributions: We sought to evolve with the literature on digital entrepreneurship in the context of startups.Social contributions/management: It is hoped that this investigation can help future digital entrepreneurs to know the necessary characteristics for this new business model.
Improving the firm innovation capacity through the adoption of standardized innovation management systems: a comparative analysis of the ISO 56002:2019 with the literature on firm innovation capacity
Authors: Silva Silvio Bitencourt da
Published: August 2021

Objective of the study: Investigate how firm innovation capacity can be improved by adopting ISO 56002: 2019.Methodology/approach: The methodology adopted is a comparative analysis of the ISO 56002: 2019 with the literature on firm innovation capacity. The methods employed in the study included a review of the literature on the dynamic capabilities and firm innovation capacity, and qualitative documentary research that consisted of three phases: pre-analysis, organization of documents, and the analysis of results, using information from the texts of the guidelines and processes indicated by ISO 56002: 2019, which additionally involved the ISO 56000 family of standards.Originality/Relevance: The adoption of innovation management standards generates several theoretical challenges when exploring details of their implementation systematically and routinely and empirical challenges such as understanding the advent of ISO 56002: 2019 for innovation management.Main results: Similarities were found between the determinants of innovation capacity and the ISO 56002: 2019 Clauses, as each of the seven factors found a relationship with one or more ISO 56002: 2019 clauses.Theoretical/methodological contributions: The findings obtained can be used by researchers interested in studying different innovation management models, innovation capacity, and, particularly, the dynamics of continuous improvement of the performance of an innovation management system and its interrelationship and interaction with other factors.Social/management contributions: Contrary to common sense in which the normalization of innovation management seems to be counter-intuitive, it is suggested that the adoption of ISO 56002: 2019 allows the innovation process to be managed, systematized, and replicated improving firm innovation capacity.
Os efeitos da aprendizagem organizacional e da capacidade de absorção no desempenho da inovação de produto em pequenas e médias empresas
Authors: Cassol Alessandra , Marietto Márcio Luiz
Published: August 2021

Objective: Verify the moderating role of absorptive capacity in the relationship between organizational learning and the performance of product innovation in small and medium-sized companies (SMEs).Methodology: The research has a descriptive quantitative approach using the survey method and questionnaires applied to 233 owners of small and medium-sized companies (SMEs). Data were analyzed using the Smart-PLS software using the structural equation modeling technique.Originality: The research used a quantitative and descriptive approach to investigate product innovation performance in the SMEs' field. Investigations into the performance of innovation in SMEs are still a limited and little-explored field in Brazil (Manthey et al., 2017; Davila, Varvakis, North, 2019). Another prominent factor was that the absorptive capacity does not act as a moderator in the relationship between organizational learning and product innovation performance, which goes against the assumptions present in the literature.Main results: The results showed that organizational learning influenced positively the performance of product innovation in the investigated companies, as well as organizational learning positively impacted absorption capacity. However, the moderating role of absorption capacity in the relationship between organizational learning and product innovation performance has not been confirmed in the field of study of the investigated SMEs.Theoretical/methodological contributions: The research showed that the capacity of absorption in the investigated SMEs could not moderate, affecting the direction or intensity of product innovation performance. This fact represents a counterpoint to the previously published literature that advocates a positive relationship between AC and innovation.Social/management contributions: The purpose of this study was to obtain more information on how SMEs absorb knowledge and transform it to improve the performance of innovations. The understanding of practices to develop the knowledge absorption capacity in SMEs is still configured as a "black box" to be explored.
SUPERVISION OF MUSEUM ACTIVITY
Authors: Golat Rafał
Published: August 2021

Supervision of museums should be perceived
taking into account both specific regulations: addressed
directly to museums, particularly in the Act on Museums,
as well as general regulations assuming supervision
mechanisms in different respects, e.g., construction process
or HR. This complex perspective: systemic and normative,
is essential not only with respect to the supervision in
a narrow basic meaning of the term, associated in the
first place with an inspection of the supervised entity
and application of respective executive actions, e.g.,
undertaken in the form of administrative decisions, but
also the supervision in a broader perspective, understood
as a whole range of support provided to a museum,
including issuing recommendations, evaluations, and
opinions important for its operation.
In the context of ‘external’ supervision implemented by
appropriate organs and entities, the following are of basic
importance: the museum’s organiser (founder) supervision,
constituting one of the organiser’s basic statutory responsibilities,
as well as the supervision of the minister responsible
for culture and preservation of national heritage, with respect
to e.g., the preservation and care of historic monuments
and museum operations; additionally, it is the matter
of conservation supervision performed by Voivodeship
Conservators of Historic Monuments as organs specialized in
the preservation and care of historic monuments, the latter
constituting, e.g., museum collections.
As for the ‘internal’ supervision aspects, the role of museum
councils, obligatory in public museums (state ones or
organised by local governments), needs to be emphasized.
Their statutory responsibility is to e.g., supervise how museums
fulfil their responsibilities with respect to the collection
and the public, in particular how they fulfil the goals as
specified in Art.1 of the Act on Museums.
The questions of supervision are also important for
non-public museums (their founders) which in the event
of violating either the Act’s provisions or their own charter
have to be prepared that supervisory activities might
be applied to them, up to the ban on their further operations.
