The Constitutional Court may be notified by the judiciary courts for the settlement of exceptions of unconstitutionality of a law or ordinance or of a provision of a law or ordinance in force, which is related to the settlement of the case. The courts have a filtering role regarding the admissibility of the referral to the Constitutional Court. If the court decides that the referral to the Constitutional Court is inadmissible, the act is subject to a specific appeal, with its own configuration, drawn up in the jurisprudence of the Constitutional Court and of the judiciary courts.
THE LEGAL REGIME OF THE LIABILITY OF THE ADMINISTRATORS OF THE COMMERCIAL COMPANIES THAT ARE ALSO THEIR EMPLOYEES
Authors:   Transilvania University of Braşov, MANEA Laura
Published: February 2022

From the logical and unitary interpretation of Law no. 31/1990 (art.72 and art.166), the liability of the administrators and auditors of the companies, who are at the same time their employees, is a civil liability - in the broad sense of the notion of civil law by applying the rules of the mandate. From the perspective of the patrimonial liability of the employees, according to the Labour Code, the ways of recovering the damage caused to the company to which you are subordinated in the employment relationship differ from the ways of recovering the damage in case of non-compliance of the mandate's limits. Analyzing the two types of liability, in the situation where the administrator also has an employment contract with the company, we conclude that the practical solution and in accordance with the concern of the legislator to prioritize the application of special law is to assess the conditions of liability of the administrator to the rules from the mandate provided by art. 2017-2024 Civil Code and Law no. 31/1990, and regarding the way of establishing the liability and recovering the damage, the provisions of art. 253-259 Labour Code.

Authors:   Transilvania University of Braşov, SALCĂ-ROTARU Cristina-Mihaela
Published: February 2022

In the context of today’s society, intellectual property rights are an important source of economic benefits. When the infringement of these rights is done with regard to products or substances that also potentially endanger the environment and human health, research on these infringements becomes imperatively necessary. This paper highlights the dual effect of infringing intellectual property rights in the field of pesticides (both in economic and environmental terms, and on human health) and it draws attention to the need for multidisciplinary research to raise awareness among potential producers and users of such products.

Published: February 2022

For many students and teachers the Covid-19 pandemic was a transformative learning experience. They were forced to cope with many changes at different levels of life: personal, professional, social. For many, the soft skills such as critical thinking, emotional intelligence, time management, being present, being empathetic or self-regulation were the main resource for effective adaptation. This is the reason why we need to adopt a new education vision, focused on developing soft skills for teachers and students, and finally for society. The aim of the present research was to analyse the respondents' perception of the soft skills which help them cope with the Covid-19 pandemic period. A questionnaire regarding teachers’ skills was used. The research sample consists of 359 respondents. An important conclusion of the study was that the respondents’ resilience was determined by the change in the perspective on the problems that arose during the pandemic.

Authors: Li Fangfang , Lukin Vladimir Vasilyevich , Okarma Krzysztof , Fu Yanjun , Duan Jiangang
Published: February 2022

Lossy compression plays a vital role in modern digital image processing for producing a high compression ratio. However, distortion is unavoidable, which affects further image processing and must be handled with care. Providing a desired visual quality is an efficient approach for reaching a trade-off between introduced distortions and compression ratio; it aims to control the visual quality of the decompressed images and make them not worse than the required by a user. This paper proposes an intelligent lossy compression method of providing a desired visual quality, which considers the complexity of various images. This characteristic is utilized to choose an appropriate average rate-distortion curve for an image to be compressed. Experiments have been conducted for Discrete Cosine Transform (DCT) based lossy compression coder, Peak Signal-Noise Ratio (PSNR) has been employed to evaluate the visual quality. The results show that our new method has the ability to provide a general improvement of accuracy, and the proposed algorithm for classifying image complexity by entropy calculation is simpler and faster than earlier proposed counterparts. In addition, it is possible to find “strange” images which produce the largest errors in providing a desired quality of compression.

Published: February 2022

In order to improve the accuracy of cloud detection in multispectral remote sensing images, this paper first proposes a deep learning framework to solve the problem of cloud detection accuracy in remote sensing images. This framework benefits from the Full Convolutional Neural Network (FCN), Cloud regions in Landsat 8 images are pixel-level labeled. Secondly, in view of the difficulty in distinguishing clouds from snow and ice regions during cloud detection, a method for removing snow and ice regions based on a gradient recognition method is proposed. Experiments show that a hybrid based on the above two methods (based on gradient recognition and deep learning) can improve the performance in the cloud recognition process, and the method can be automatically generated without manual correction. The Jeckard index and recall rate increased by an average of 4.36% and 3.62%, respectively.

Published: February 2022

Background and Objectives: People are always looking for new ways to achieve a good and healthy life. They associate such a life with wellbeing and happiness. The World Health Organization defines health as a form of wellbeing, in which each person identifies his or her abilities and plays a role in society effectively. Many studies have shown the correlation between moral virtues and psychological wellbeing. This research aims to study the role of militancy/ peacefulness morality in predicting psychological wellbeing among university students. Methods: This research was a correlational study. The sample size was calculated based on Kline guideline. We included in our study 530 (226 males and 304 females) undergraduate students in humanities, engineering, basic sciences, art, and architecture. They were selected by random cluster sampling method from different faculties of Shiraz University, Shiraz City, Iran, from January to September 2019. Then, they responded to Ryff’s psychological wellbeing scale and researcher-made militancy/peacefulness scale. The obtained data were analyzed using structural equation modeling in AMOS software. Results: Their Mean±SD total scores of wellbeing and militancy were 21.62±4.54 and 52.75±10.15, respectively. The results of analytical statistics showed that militancy/peacefulness (such as hatred, mischief, slander, and stupidity) is a negative predictor of psychological wellbeing. The obtained results of this analysis also showed that the final model of the study has good fitness. Conclusion: Considering the findings of this study, we recommend teaching peaceful behaviors in universities by using educational workshops in the field of moral virtue.

Authors: Hu Xinghua , Chen Xinghui , Liu Wei , Dai Gao
Published: February 2022

An effective way to solve the problem of urban traffic congestion is to predict the road traffic status accurately and take effective traffic control measures in time. Considering the impact of visibility on traffic, the pavement status and time characteristics were finely divided, and a regression decision tree was used to establish the traffic flow velocity prediction model with pavement status, time characteristics, and working day characteristics as characteristic parameters. Furthermore, based on the perspective of avoiding using velocity as a single parameter to classify the road traffic status levels, the Kmeans clustering algorithm was used to obtain the classification label results. Moreover, the traffic flow velocity and pavement status were used as characteristic parameters of the classification decision tree to establish the multi-parameter road traffic status prediction model. The experimental result showed that the prediction accuracy of the proposed road traffic status prediction model was 81.31%, and this method has good applicability and certain application value for road traffic status prediction.

Methodical approaches to optimizing the insurance company portfolio of services
Authors: Tkachenko K. , Paska I.
Published: February 2022

The article is devoted to the generalization of methodological approaches to the optimization of the insurance company portfolio of services and the development of an algorithm for optimizing the insurance company's services portfolio.
Insurance market of Ukraine is in a state of transformation, which is associated with changes in the institutional conditions of insurance, changes in the priorities of policyholders, macroeconomic instability, the spread of the COVID-19 pandemic.
Institutional changes in the insurance market of Ukraine and macroeconomic instability have led to the "cleansing" of the insurance market and the exit of insurance companies that do not ensure transparency, solvency and efficiency. In the three quarters of 2021, 41 insurance companies left the Ukrainian insurance market, ie one in five insurance companies ceased operations.
The relevance of optimizing the insurance company's portfolio of services is proved, which is due to the need for insurance companies to review their own portfolios to ensure financial stability, solvency and efficiency in a competitive insurance market of Ukraine.
It is proposed to consider the optimization of the insurance company's portfolio of services as a set of interconnected and consecutive stages that are consistent and logical, as well as adaptive to modern realities of the insurance market of Ukraine, aimed at achieving profitability and maximizing the value of the insurance company.
The first five stages of optimizing the insurance company's portfolio should be considered the most important, as it provides for determining the methodological principles of optimizing the insurance portfolio.
Substantiation of the type of insurance company's portfolio and justification of the list of criteria for optimizing the insurance company's portfolio are interrelated stages that determine the individual basic parameters of the optimized portfolio for the insurance company depending on the chosen type of portfolio. Calculations for the optimization of the insurance company's portfolio of services involve the implementation of economic and mathematical modeling of the structure of the insurance services portfolio and the definition of its targets. Following a certain period of time, the insurance company must assess the effectiveness of achieving the optimal portfolio of services of the insurance company and the impact on key performance indicators of the insurance company, including net financial result and value of the insurance company, the presence of deviations of actual and optimal indicators.

The study aims to estimate and compare the global emission for 20 halocarbons from volcanic and hydrothermal sources into the Earth’s atmosphere. It follows from the results that the contribution of volcanic emission for these species in the depletion of stratospheric ozone in the catalytic halogen cycles does not exceed 0.1%. Still, they significantly impair the level of tropospheric ozone near the volcanoes. The scheme of gas-phase free radical chain halogenation of the hydrocarbons is proposed and confirmed by thermodynamic and kinetic calculations. This explains the experimental ratios between concentrations of CH3I : CH3Br : CH3Cl and CCl4 : CHCl3 : CH2Cl2 : CH3Cl in the volcanic gases. The possible volcanic emission of halocarbons from Erebus and explosive eruptions in the Southern Hemisphere during the Holocene do not have a notable impact on their content in the Antarctic ice. However, volcanic emission of hydrogen halides (HX, X = Cl, Br or I) from powerful eruptions in the Southern Hemisphere during Holocene could deplete the stratospheric ozone substantially, causing a drastic impact of the harmful UV-B radiation on the biota of continents and ocean. We calculated the injected Equivalent Effective Stratospheric Chlorine values and estimated the column ozone percentage change, Δ%O3, for 20 known volcano eruptions in the tropical belt and Southern latitudes. The estimates lead to more than 50% depletion of stratospheric ozone after past powerful volcanic eruptions. The range is estimated for possible ozone depletion after the eruption of Deception Island’s volcano occurred near 4000 BP (from 44 to 56%), which is comparable with those from Krakatoa, Samalas, and Tambora eruptions. A similar analysis was carried out for 192 yrs series of Mt Takahe (West Antarctica) halogen-rich volcanic eruptions at 17,7 kyr, showing extensive stratospheric ozone depletion over Antarctica. Crude estimations of stratospheric ozone depletion (Δ%O3) after Ferrar Large Igneous Province eruptions (183 Ma) in Antarctica were performed, considering the whole LIP volume of basaltic lavas, and they range from 49 to 83%. Given the very low emission rate of HCl due to non-eruptive degassing of the Mt. Erebus volcano, the volcanic emission of Erebus could not be a fundamental reason for modern springtime ozone hole formation over Antarctica.

The study’s primary purposes were establishing the number of microorganisms that exhibit hydrolytic activity in Antarctic soil and mosses samples, isolation of metal-resistant strains of bacteria, and description of their physiological and biochemical properties. Samples collected during the XXIII Ukrainian Antarctic Expedition in 2019 were used. The number of colony-forming units of microorganisms exhibiting proteolytic, amylolytic, cellulase, lipolytic activity was studied. Pure bacterial cultures were isolated using standard microbiological methods. Determination of resistance of isolates to heavy metals was estimated after their cultivation during ten days on agar plates with different concentrations of CdCl2 ⋅ 2.5H2O, CoCl2 ⋅ 6H2O, K2Cr2O7, FeSO4 ⋅ 7H2O, CuCl2 ⋅ 2H2O. Identification of strains was based on the sequencing of the 16S rRNA gene, morphological, physiological, and biochemical properties. Among the 23 isolates, nine metal-resistant strains were selected, four of which were identified as Pseudomonas yamanorum ІМV B-7916 and 79_102, and as P. arsenicoxidans 5A_1N_24, and 89_1T_89. Among the selected strains, the most resistant to heavy metals was P. yamanorum 79_102. All studied strains synthesize lipases during growth on medium with tween-20, which contains 0.5–1 mM of ferrous sulfate and copper (II) chloride. The studied strains produce exopolysaccharides during growth at 6 and 22 °C. The most effective among these strains exopolysaccharides are synthesized by P. arsenicoxidans 5A_1N_24 — 768 mg/g of dry weight. Our results expand the knowledge about the diversity of microorganisms of extreme biotopes, their properties, resistance to heavy metal compounds.

The immune system plays a major role in human homeostasis, yet a body’s unique individuality complicates the diagnostic forecasting of unfavourable physiological states and diseases. Studying the immunophenotypic features of winterers of the Ukrainian Antarctic Expeditions before, during, and after their assignments might shed some light on the possible place of immune accentuations in the development of certain physiological states. To determine the natural-killer (NK) cytotoxicity and the immunophenotype in 52 applicants who wanted to take part in an expedition and nine participants who had come back, we used flow cytofluorometry. Blood serum samples taken before, during, and after the expeditions were also tested for hormones, anti-infective, anti-parasitic, and autoimmune antibodies. The high absolute and relative numbers of NK lymphocytes, high NK cytotoxicity, and high expression of HLA-DR on the CD3+CD8+ lymphocytes were correlated with a person’s unfavorable health status during the expedition. In Antarctica, cortisol levels sharply increased, yet they normalized upon return. In most winterers, there were no significant health complications during the expeditions. Neither reactivated nor primary viral infections were registered, as well as clinical autoimmune ones. Upon return, the winterers had significantly lower leukocytes and lymphocytes and increased expression of activation markers (HLA-DR) on the T-cells. The found risk factors can characterize the polar researchers’ immunophenotypes yet require validation on larger samples. The expedition environment causes increased stress, entailing, however, neither clinical manifestations nor elements of immunosuppression. The polar researchers bear the consequences of the prolonged stress that inhibit leucopoiesis as late as six months after their return, which should be considered while reviewing applications for the next season.

The diversity of psychrophilic / psychrotolerant microorganisms from Antarctica is a preferred subject of study by microbiologists, in turn, the communities of endolithic and hypolithic yeast cultures are practically not studied, and the literature on the biotechnological potential of such microorganisms should cover important biomolecules in addition to cold-adapted enzymes. In order to study the characteristics and biopotential of yeast cultures isolated from soil samples of East Antarctica, a number of physiological and biochemical tests were carried out. This article provides a list of the studied morphological characteristics, and also describes the results of the study of enzymatic activities and biochemical properties. In the course of research, it was revealed that Antarctic yeast isolates have a wide range of enzymatic activities when growing on agar media: most isolates were characterized by the presence of lipolytic, amylolytic, DNase, urease activities and the production of esters; a much smaller number of isolates were capable of manifesting proteolytic, cellulolytic and pectolytic activities, the release of organic acids and the formation of starch-like compounds. The study of tolerance to stress showed the presence of resistance of the studied cultures to the effects of ultraviolet radiation with a wavelength of 254 nm and low concentrations of copper sulfate in the environment. A qualitative assessment of the level of glycogen in yeast cells by staining with Lugol's solution showed that one culture is capable of accumulating glycogen in significant amounts. Additionally, the ability of yeast cells to accumulate lipids with increasing age of cultures was shown. The destruction of the surface of the mineral motor oil by the culture broth made it possible to identify yeast isolates with high destructive activity. This experience allows us to consider Antarctic yeast cultures as promising producers of biologically active compounds. The variety and spectrum of physiological activities of the investigated isolates allows us to consider them as promising producers of biological compounds for use in medicine and biotechnology.

With the strengthening of the global environmental movement, the Southern Ocean has become an effective international testing ground for the development of spatial planning in marine environments beyond national jurisdiction. This note aims to review the European Union (EU) role in the progress on designation of environmentally representative network of marine protected areas (MPAs) in Antarctica, and the effect of this process on the shaping of Ukraine’s strategy in this region. Following Ukraine’s external vector to European integration, in 2021 the country began formally aligning as a co-proponent with the EU-initiated two MPA proposals — in East Antarctica and the Weddell Sea. This alignment of positions is utterly important, taking into account the approaching of Ukraine's first chairmanship of the Commission for the Conservation of Antarctic Marine Living Resources in 2023–2024, which would be an exceptional opportunity for our country to make a significant progress in designation the largest MPAs ever implemented in Antarctica given national interests, including the creation of an international consortium with the involvement of Ukrainian scientific infrastructure in Antarctica, such as Ukrainian Antarctic Akademik Vernadsky station and the research vessel Noosfera, to implement internationally significant scientific and monitoring programs to evaluate MPAs efficiency with Ukraine as a co-initiator.
Nocardiosis in the Illawarra-Shoalhaven region from 2010 to 2019
Authors: Gray Darcy , Crawford Simeon , Newton Peter
Published: February 2022

Nocardia species are a diverse group of gram-positive bacteria that are encountered as pathogens in clinical practice. They are ubiquitous environmental organisms classically causing opportunistic infections in immunocompromised individuals. This case series describes the epidemiological, microbiological and clinical features of 26 culture-proven cases of nocardiosis presenting to the public healthcare service in a regional area of New South Wales over a ten year period. These cases involved ten distinct species of Nocardia and appeared to demonstrate increasing incidence over time. The majority of Nocardia isolates (88%) were grown on conventional bacteriological media and speciation was primarily via 16S rRNA sequencing and/or matrix assisted laser desorption ionisation—time of flight mass spectrometry. Similar to other Australian Nocardia studies, the isolates seen in this case series were universally susceptible to trimethoprim-sulfamethoxazole. This was reflected in treatment data, with all but one patient receiving this agent as part of their antibiotic regimen. While similar case series have been reported from other Australian states, there are no published clinical studies of nocardiosis in New South Wales. Given the nature of Nocardia species as an environmental saprophyte, this study examined the association between incidence of nocardiosis and regional geographic or climatic variation but was unable to demonstrate a statistically significant correlation.

Assets are one of the supporting equipment for business processes in a higher education organization. Asset management requires a system that is organized systematically so that the tracing process becomes more effective and efficient. In this case, asset management can be implemented in a web-based information system. The development of a web-based asset management information system is carried out using the waterfall method, and for decision making in asset procurement priorities using the Analytical Hierarchy Process (AHP) method. The system development process uses the Codeigniter framework based on PHP and MySQL. The result of this development is a web-based asset management information system that is used to optimize asset tracking which is implemented at ITS NU Pekalongan

Radiation shielding is an imperative as radiation can be serious concern within in such environment, where this environment can be either natural or man-made. The natural radiation source like solar wind that is consisting of Electron, Gamma, Protons, Neutrons, or Van Allen Belt, etc. while, the source of man-made is nuclear power facilities or either Exo- tmospheric or Endo-Atmospheric nuclear explosion. The effects of nuclear explosions produce both immediate and delayed destructive effects, that requires choice of right and proper protective materials for ICs to be shielded and survivable in such radiation environment driven by a nuclear weapon burst. Nuclear weapon effects in term of blast, thermal radiation, electromagnetic pulse, and prompt ionizing radiation, etc. are part of concerns for choosing the proper materials. Radiation shielding is based on the principle of attenuation, which is the ability to reduce a waves or ray’s effect by blocking or bouncing particles through a barrier material. This short review is discussing different holistic issues in respect to selected materials and integrated circuits in respect to survivability and shielding within a radiation environment, either man-made or natural.

There is a demand for the development of products in a shorter time that resulted in the introduction of 3D printing which is also termed as “Additive Manufacturing” (AM). This technology has many advantages such as costeffectiveness, less manufacturing time and elimination of post-processing costs. Intensive research is being carried out on cellular structures manufactured using additive manufacturing technologies. Cellular structures have many applications in various areas. When compared to solid structures, these cellular structures possess high strength to weight ratio, good energy absorption characteristics, good thermal and acoustic insulation properties. They are used for aerospace, medical and engineering products. There are many additive manufacturing technologies whereas fused deposition modelling (FDM) is the most versatile one. This research consists of the analysis of hexagonal honeycomb structure by creating honeycomb structures of different dimensions in SolidWorks and manufacturing of those structures by using the FDM additive manufacturing process. These structures were designed by varying the internal hexagon’s wall thickness and side length. After printing these structures were subjected to Mechanical testings like tensile, compression, three-point bending, impact and thermal testing like heat deflection temperature tests. The three-point bending test was simulated numerically and compared with the experimental results. This study is finally validated by comparing experimental and simulation results, which were in agreement with each other. Experimental results show that the low-weight specimen exhibited good mechanical and thermal properties with a lesser printing time compared to the remaining specimens. The specimens with different hexagonal cell dimensions were introduced and discussed.

A política educacional se enquadra no tipo de política majoritária, em que o governo tem responsabilidade e competência em oferecer a todos os brasileiros a educação básica, com acesso, permanência e qualidade, e faz parte dos direitos constitucionais do cidadão brasileiro no artigo 5º da Constituição Federal de 1988. A educação pública tem legislação própria, que determina, diretrizes, funções e seu funcionamento: a LDB n.º 9.394/1996, conjuntamente com o PNE, Lei n.º 13.005/2014, estabelece metas, estratégias e ações para a educação brasileira pelo período determinado de uma década.  A formação de professor é uma política pública que busca responder pela qualificação do ensino público e vencer os desafios que permeiam os contextos escolares, fato que compromete a aprendizagem dos alunos, além de promover valorização profissional ao docente. O artigo expressa a correspondência dos objetivos estabelecidos no Programa de Formação Continuada de Professor da Educação Infantil, realizado pela rede pública municipal de Fortaleza no período de 2017 a 2018, investigando os resultados obtidos segundo as narrativas dos sujeitos pesquisados. O programa de formação continuada em 2017 teve por objetivo a reelaboração da proposta pedagógica das instituições públicas municipais de Fortaleza. Em 2018, o objetivo elegeu o fortalecimento do currículo da educação infantil, com a pedagogia de projetos, para promover os direitos de aprendizagem das crianças estabelecidos na BNCC (Brasil, 2017). A pesquisa foi realizada em unidades escolares do Distrito 3, no período de setembro a novembro de 2020. O público-alvo foram professores, coordenadores pedagógicos e técnicos-formadores com atuação na etapa da educação infantil, segmento pré-escola. A literatura pesquisada utilizou de documentos pertinentes a educação pública das esferas: nacional, estadual e municipal. Segundo as narrativas dos sujeitos, foi possível concluir que, em 2017, o objetivo proposto foi alcançado em sua plenitude, mas em 2018, não foi possível lograr de pleno êxito, em virtude dos fatores que envolvem as concepções e os conhecimentos no âmbito do currículo da educação infantil.

O consumo de corantes artificiais vem preocupando os consumidores, o que impulsiona as pesquisas com corantes naturais e sua aplicação em alimentos. As antocianinas são uma classe de compostos com potencial para a utilização como corantes alimentícios, devido à sua abundância na natureza, extensa gama de cores e efeitos benéficos à saúde, com comprovada capacidade antioxidante. O capim-gordura (Melinis minutiflora), por sua vez, é uma fonte promissora de antocianinas, devido ao seu baixo custo e à presença de antocianinas metiladas em sua composição. O presente trabalho teve por objetivo a obtenção de um corante natural a partir de antocianinas de capim-gordura e sua aplicação em iogurtes. A extração das antocianinas de capim-gordura foi otimizada por meio de um Delineamento Composto Central Rotacional (DCCR) de duas variáveis, 8 ensaios e três pontos centrais, onde foram definidas as condições ótimas de 15 g de capim para 50mL de solução extratora, com 38,5% de etanol. Os extratos obtidos a partir das condições ótimas foram rotaevaporados para a retirada do etanol e liofilizados, obtendo-se no final um corante concentrado. Foram obtidos dois tipos de iogurtes, com e sem a aplicação de corante e avaliados quanto ao pH, acidez, capacidade de retenção de água e coloração durante 27 dias de armazenamento. Os iogurtes demostraram boa estabilidade ao armazenamento, com redução na intensidade de cor a níveis não perceptíveis a olho nu. Os resultados demostraram o potencial da utilização de corante natural de capim-gordura para esse tipo de matriz alimentícia.
