Standard naš svagdašnji
Authors: Stanić Rašin Irena
Published: March 2023

Rad preispituje Silićevu klasifikaciju funkcionalnih stilova i njihov odnos prema standardnom jeziku. Razmatraju se nazivi koji se u toj klasifikaciji koriste, s posebnim osvrtom na “književnoumjetnički funkcionalni stil” i “razgovorni funkcionalni stil”. Preispituje se raslojavanje funkcionalnih stilova u suvremenoj hrvatskoj jezičnoj zajednici, i to uz pretpostavku (na tragu pitanja “Govore li Hrvati hrvatski? koje je inspirirano podnaslovom “Govore li Senegalci senegalski?” iz Škiljanova Govora nacije (2002)”) da se, zbog različitih komunikacijskih potreba, ne služe svi govornici svim funkcionalnim stilovima te da su većini govornika najpoznatiji i u svakodnevnoj komunikaciji najbliži razgovorni i publicistički stil. U cilju doprinosa rješavanju jezičnih nedoumica u standardu i njegovim stilovima, kao i u razlikovanju standarda i nestandarda, predlaže se shematska redefinicija funkcionalnih stilova hrvatskoga standardnog jezika, uključujući njihova preklapanja, suodnose i nazive, kao i odnos prema nestandardnim idiomima. Osuvremenjena shema razlikuje termine “funkcionalni stil”, koji pripada standardu, i “jezik”, koji označava idiome koji pripadaju nestandardu, pa se predlaže uvođenje pojmova “književni jezik” i “razgovorni jezik” za dva idioma koja jednim svojim dijelom izlaze iz domene standardnoga jezika. Predložena klasifikacija negira postojanje „književnoumjetničkoga funkcionalnog stila“, već ga, vodeći se dosadašnjim kritikama toga stila kao sastavnoga dijela standardnoga jezika, proširuje na “književni jezik” koji služi kao “podloga” svim standardnim i nestandardnim idiomima. Predložena shema ostavlja dovoljno prostora za uvođenje i sistematizaciju žanrova, podstilova i međustilova koji su već obrađeni u literaturi.
Deiodinases in thyroid tumorigenesis
Authors: Angela De Stefano Maria , Porcelli Tommaso , Schlumberger Martin , Salvatore Domenico
Published: March 2023

The three deiodinase selenoenzymes are key regulators of intracellular thyroid hormone (TH) levels. The two TH-activating deiodinases (type 1 deiodinase and type 2 deiodinase (D2)) are normally expressed in follicular thyroid cells and contribute to overall TH production. During thyroid tumorigenesis, the deiodinase expression profile changes to customize intracellular TH levels to different requirements of cancer cells. Differentiated thyroid cancers overexpress the TH-inactivating type 3 deiodinase (D3), likely to reduce the TH signaling within the tumor. Strikingly, recent evidence suggests that during the late stage of thyroid tumorigenesis, D2 expression raises and this, together with a reduction in D3 expression levels, increases TH intracellular signaling in dedifferentiated thyroid cancers. These findings call into question the different functions of TH in the various stages of thyroid cancers.

Published: March 2023

Background: Due to its high morbidity and mortality after open-heart surgery, sternal wound infection (SWI) is one of the most important consequences to avoid and manage.
Aim: To assess the incidence, risk factor, causative organisms, and mortality of SWIs in patients who had open-heart surgery over a 9-year period at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.
Methods: A retrospective study was done on 634 patients who underwent open heart surgery. Data was collected, including patient demographics, BMI, blood group, diabetes, hyperlipidemia, COPD, previous cardiac surgery, previous myocardial infarction, duration of the operation, blood transfusion during the operation, hospital length of stay, and bypass time with each type of sternal wound infection.
Results: The incidence of SSWI and DSWI was 8.6% and 4.1%, respectively. Coagulase-negative staphylococcus was the most frequently isolated organism from SSWI and DSWI patients. A concomitant diabetes mellitus that necessitates blood transfusion was identified as one of the risk variables for SSWI in a multivariate regression study. While concomitant diabetes, being a woman, and a lengthy hospital stay were independently linked with DSWI. Compared with the SSWI group, the 30-day mortality rate for DSWI patients was 3.8% as opposed to 3.7%, and the difference in survival was not statistically significant. Having an older, longer bypass time, and postoperative problems were independent risk factors for 30-day mortality.
Conclusion: Future studies in various healthcare settings are required in order to generalize the results because this was a single center study.
Cognitive Dysfunction in Hypothyroidism
Authors: Rakugi Hayashida
Published: March 2023

Cognitive function and hypothyroidism are strongly associated, and age-related differences in performance are significant. The association between hypothyroidism and cognitive impairment in adult patients is still debatable, although it is most severe in the fetus and neonatal period, where it is easy to leave lasting sequelae. Current theories postulate that the various age-related manifestations of this cognitive impairment may be linked to the various stages of hypothyroidism during the time-dependent development of the neurological system. Although the precise mechanism is still not entirely understood, it might be connected to immunological factors.
Pre-service Primary School Teachers’ View of Nature of Science Helps Decision-making on Socio-scientific Issues
Authors: Qu Liaojian
Published: March 2023

Since the 20th century, science and technology have developed rapidly, and the industrialization and modernization of countries around the world have been in full swing. In this context, the education of Socio-scientific issues (SSI) in classroom teaching in primary and secondary schools becomes particularly important. SSIs can serve as an important carrier for scientific, ethical, and moral education, an important path to develop the core competencies of individuals in the 21st century. As future teachers, pre-service primary school teachers receive good science education in the university, develop fundamental scientific literacy, and obtain a basic understanding of nature of science (NOS). Their mastery of NOS has a significant impact on their decision-making skills on SSIs. In science education for pre-service primary school teachers, more attention should be paid to improving their comprehension of NOS and critical thinking ability.
The Education of Nature of Science in the Internet Era
Authors: Zhang Qing
Published: March 2023

Modern science and technology can not only promote social development for the benefit of mankind but may also cause catastrophic consequences if improperly employed. They are the two sides of the same coin. Science education plays an increasingly important role in the rapidly developing human society. With the rise of new educational strategies in the “internet plus education” era, the education of nature of science (NOS) exhibits its significant value in contemporary primary science curricula (Zhu & Yu, 2008). Science is not about conclusive truth. The history of science has witnessed numerous controversial issues which often sparked intense debate. The introduction of socio-scientific issues (SSI) to science education allows students to experience the process of scientific development. NOS education concerning scientific questioning, experimentation, and investigation and the establishment of scientific laws and theories as well as their application is of great significance to the development of teaching philosophy and methods in pre-service primary school teachers (Liu, 2003). It also poses new requirements and challenges in the reform of basic education in the internet era.
Environmental Sustainability in Science Education in the Anthropocene: A View from STEAM Education
Authors: Gülhan Filiz
Published: March 2023

Environmental problems in the age we live in require us to think differently, to question them, and to do something corrective. The role of science education in the transformation of education and its adaptation to the age is perhaps more than in previous periods. Because at the end of the day is the continuity of our planet. This article examines science education and higher-order thinking skills in the Anthropocene era and presents examples from studies on environmental sustainability as a prominent concept in this field. In addition, it argues that STEAM education is one of the ideal approaches that can meet this goal by presenting examples of what can be done with a holistic and interdisciplinary view of environmental sustainability within the framework of STEAM education. Suggestions are made through STEAM training, with the assumption that environmental sustainability in an intricately connected network structure rather than linear chains can only be understood with an interdisciplinary approach and solutions can be found only in this way.

Published: March 2023

A study was carried out in order to identify the aspects of geochemical processes occurring during the formation of green and light-blue amazonite crystals. Green, light-blue and greenish-blue amazonites from rare-metals deposits of Ukraine (Perzhanske, Ukrainian Shield), rf (Gora Parusna, Ploskogirske, Kola Peninsula; Orlovske, Western Transbaikalia), and USA (Rutherford, Virginia) were investigated using X-ray luminescence (XRL), infrared (IR) spectroscopy and X-ray diffraction. The rock-forming microcline from the Perzhanske, Orlovske and Katuginske (rf) deposits was also studied. It was found that the multi-colored crystals of amazonite have similar degrees of Si/Al ordering. They are represented by the maximum microcline with 2t1 = 0.959-1.0. The various samples only differ significantly in their lead contents that range between 2000 and 10000 ppm in green amazonite and 200 ppm in light-blue colored crystals. Differences between untreated crystals and those annealed in air (1173 K) or under a stream of He (923 K) samples were observed in terms of the composition, ratio of optically active centers and oxygen-hydrogen defects. Their composition and concentration in the untreated natural crystals reflect the genesis conditions of parent rocks, and, first of all, the redox and fO2 conditions of water-containing fluids, which affect the isomorphism of plumbum in the structures of the green and light-blue crystals, mechanisms of crystal chemical compensation of Pb2+ ions and correlates with different degree of ferum oxidation (Fe3+ → Fe2+). Changes in redox and fO2 parameters of the mineral-forming fluid are the most important factors affecting the activity and acid-base properties in the residual water fluids, the process of reduction following 2H2O + 2e– → H2 + 2OH– or oxidation via 2H2O – 4e– → O2 + 4H+. A complex combination of these factors allows the formation of certain nanosized defects in the structures of the amazonite crystals. These include impurity ([Pb2+ – Pb+]3+) and impurity-vacancy (Pb2+ – VK) clusters that serve as chromophore centers for green and light-blue color, respectively.
EPR CHARACTERISTICS OF FELDSPARS FROM GRANITES OF RUSKA POLYANA MASSIF OF KORSUN-NOVOMYRHOROD PLUTON (UKRAINIAN SHIELD)
Authors: Larikov A.L. , Zaiats O.V. , Bagmut M.M.
Published: March 2023

The electronic paramagnetic resonance spectra of microfractions of microcline, plagioclase and albite from the Ruska Polyana granites of the Korsun-Novomyrhorod pluton located in the Ukrainian Shield were measured. The results are used together with chemical and X-ray fluorescence analyzes to study the nature of Fe and Mn in the feldspars. It is shown that structural Fe3+ in the microcline and plagioclase reflect the iron content in the melt during crystallization of the granite. At the same time, nonstructural impurities of Fe3+ and Mn2+ in the feldspar monofractions, which are part of hydroxides and carbonates along grain boundaries, do not show correlations with structural impurities of Fe3+ replacing Al3+ ions in microcline and plagioclase, and presumably reflect postcrystallization processes. The ratio of the intensities of the Fe3+ EPR lines in the spectra of microcline indicates that its ordering temperatures are close to 670 K for all studied samples.
Factors affecting nanofluids behaviour: A review
Authors: Alktranee Mohammed , Bencs Péter
Published: March 2023

Nanotechnology applications have occupied a wide range in engineering applications and achieved distinctive performance due to their potential as a working fluid instead of conventional liquids due to their outstanding performance. Sustaining stable performance nanofluids for a longer time retaining their properties without clustering and nanoparticles aggregation in the base fluid represents a significant challenge that can influence nanofluid properties and thermal behaviour. This review highlights some important factors that influence the stability of nanofluids, such as the size, concentration ratio of nanoparticles, and the type of base fluid, in addition discussing the methods used to improve the stability of nanofluids, such as the effect of cluster formation of nanoparticles in the base fluid due to Brownian motion and the role of the surfactants in preventing or reducing the agglomeration of nanoparticles, zeta potential and pH in estimating nanofluids stability. The factors mentioned affect the thermophysical properties of nanoparticles in preparing nanofluids and enhance their performance. This review provides information which helps improve the wide range usability of nanofluids for preparing stable nanofluids with good thermophysical properties.

Aim of the study: Droughts are one of the more costly natural hazards on a year-to-year basis. Their impacts are significant and widespread, affecting many economic sectors and people at any one time (WMO & GWP, 2016). In our paper we will focus on the comparison of meteorological drought (precipitation) and agricultural drought (available soil water) in the Nitra River basin, Slovakia. Material and methods: Data from the Nitra River Basin were provided from the meteorological stations (Svinná, Bystričany, Solčany, Veľké Ripňany, Jelenec and Pribeta ) of the Slovak University of Agriculture in Nitra. The meteorological drought is defined as a period with no precipitation (Petrovič, 1960). Agricultural drought was determined as the value below the amount of water storage in the soil profile (0.20 m) accessible to plants. Results and conclusions: We focused on the comparison of meteorological drought and the number of days with both type of drought is from year 2014 increasing. The worst year was 2018 in every meteorological station, when the agricultural drought was with short interruptions from sprig to winter. This trend can also be seen in the countries neighbouring Slovakia - Poland, Hungary or Czech Republic.

Aim of the study: The aim of the study was to evaluate changes in the concentration of selected ions in the waters of the Słupsko dam reservoir and to determine its role as a "primary sedimentation tank" for the Pławniowice reservoir. Material and methods: Determination of the factors causing these changes was made on the basis of measuring a number of physical and chemical parameters between March 2019 and February 2020. The research was carried out in terms of checking the potential of unfavorable phenomena for surface water and checking whether the Słupsko reservoir fulfills the assumed role, i.e. the function of the "initial settler" for the Pławniowice Reservoir. Results and conclusions: The Słupsko reservoir contributes only to a small extent to the equalization of the analyzed ions' concentrations . It is difficult to explain the lack of a clear relationship between sodium ion concentrations and conductivity. High concentrations of orthophosphate ions in the summer may suggest that the reservoir's canopy is enriched with this element internally in the summer. High concentrations of orthophosphates at the inflow to the reservoir may indicate the inflow of insufficiently treated municipal sewage or runoff from agricultural areas. The Słupsko reservoir plays only a marginal role as a "preliminary sedimentation tank" for the Pławniowice reservoir. The short time of water retention does not allow the removal of nutrients from it. Currently, the Słupsko reservoir is a potential source of nutrients for the Pławniowice reservoir. Therefore, it seems necessary to constantly monitor the quality of water in the reservoir.

THE LIPÓWKA LANDFILLS: A CASE STUDY IN GROUNDWATER QUALITY ASSESSMENT
Authors:   Faculty of Natural Sciences, University of Silesia, Będzińska 60, Sosnowiec, Dąbrowska Dominika
Published: March 2023

Aim of the study: Groundwater quality monitoring tests in the area of pollution sources are one of the elements of the assessment of groundwater vulnerability. The aim of the article is to indicate a good index for the assessment of water quality and the selection of an appropriate value of the hydrochemical background. Material and methods: The quality of groundwater in the region of the municipal landfills in Dabrowa Gornicza (southern Poland) was assessed in the context of the content of ammonium, chlorides, sulphates, iron and electric conductivity values . The level of the contamination of groundwater was determined on the basis of the monitoring data from 2016-2020. The research used the Landfill Water Pollution Index (LWPI) and the Nemerow index (NI). In order to determine the reliability of the methods used, three different values of the hydrochemical background were taken into account. Results and conclusions: The results of the analyses show that the values of the Nemerow index are definitely higher than the LWPI index. Additionally, the highest values of the indicators were obtained when comparing the obtained results to the hydrochemical background from the 1980s. The maximum values of the indicators were approx. 156 (LWPI) and approx. 721 (NI) for the PZ4 piezometer located east of the landfills. The differentiated results of the index values depending on the selection of the background value and the assignment of individual weights indicate that for such a transformed area it is difficult to indicate the value of the hydrochemical background for which the index values would be representative.

Aim of the study: The goal of this study was to apply SWAT+ tools to estimate the water shortage in the Smugawka catchment. Material and methods: The use of the area was documented in the form of an orthophotomap with GIS layers superimposed, which was provided by CORINE Land Cover 2018. A soil and agricultural map, supplemented with lithological content from a detailed geological map, was used as the input layer for QGIS ver. 3.16. In the next stage, multiannual meteorological data (1991–2020) were added to the SWAT+ model, which included: minimum and maximum daily air temperature, daily rainfall, average daily radiation and average daily wind speed. Full integration of the SWAT+ model with QGIS facilitates the procedure of iterative generation and modification of the model input parameters. The calculation of continuous simulations for average long periods of time is presented in the manuscript. Results and conclusions: The application of GIS-based approaches and modeling techniques are crucial in the quest for optimal methods for calculating the water balance today. Our findings also contribute to a better understanding of the hydrological processes at work in the flysch catchment.

Factor influencing the survivability of Tetragenococcus halophilus CH6-2 in the spray drying process
Authors: Ha Le Thanh , Nguyen Trung Thanh , Vu Thi Kieu Oanh
Published: March 2023

In this study, several factors affecting Tetragenococcus halophilus CH6-2 cell survival rate in spray drying process including growth conditions, protective agents, and stress adaption were investigated. T. halophilus CH6-2, which was grown in different media, was mixed with different protective agents or at different ratios of cell concentration to protective agents or was subjected to stress adaption before spray drying. The survival rate after spray drying and after storage was determined. The results showed that skim milk had the strongest protective effect on T. halophilus CH6-2 cells during spray drying. De Man, Rogosa and Sharpe (MRS) was a better medium than our developed M7 optimal medium for culturing T. halophilus CH6-2 in respect of survivability after storage. Increasing the cell/protective agent ratio from 1/20 to 1/3 could increase the survivability after spray drying but not during storage. The heat stress and osmotic stress in this study did not improve the cell survivability after spray drying and storage.

The Garcinia genus belonging to the Clusiaceae family (Guttiferae) has been reported to be a rich source of polyisoprenylated benzophenones, xanthones and biflavonoids with various biological activities. Garcinia fagraeoides A.Chev is an evergreen hardwood tree found only in the north provinces of Viet Nam and Guangxi province of China. Its stem bark and leaves have been used in Vietnamese traditional medicine for treatment of malaria and dermatitis diseases. In our continuing studies on chemical constituents and biological activities from the genus Garcinia, the phytochemical of Garcinia fagraeoides’s stem bark collected from Thua Thien Hue province was investigated. Repeated chromatography steps over silica gel and Sephadex LH-20 of the dichloromethane partition from the methanol extract of  Garcinia fagraeoides’s stem bark led to the isolation of five compounds including one polyisoprenylated benzophenone (isogarcinol (1)), two tetraoxygenated xanthones (rubraxanthone (2), a-mangostin (3)), ferulic acid (4), and pyromeconic acid (5). Their structures were elucidated mainly by analysis of their 1D, 2D NMR spectroscopy and ESI-MS data, and by comparison with reported data. The absolute configuration of isogarcinol (1) was determined by comparison of its experimental optical rotation and NMR data with the values of its stereoisomer. This is the first reported isolation of compounds 1-5 from the stem bark of Garcinia fagraeoides.

Published: March 2023

. Electroactive poly(1,8-diaminonaphthalene) is known to have a high affinity for metal ions thanks to amine and imine groups in the polymer chain. However, electrochemical sensors based on pristine P(1,8-DAN) have a major drawback concerning its poor electrical conductivity. To solve this problem, recently P(1,8-DAN) has been modified with some advanced nanomaterials such as carbonaceous materials or different metallic elements. In this research, we reported the synthesis and electrochemical characterization of a poly(1,8-diaminonaphthalene)/graphene composite film capable of adsorbing Cu2+ ions towards the application of nitrite sensing. P(1,8-DAN) was directly electropolymerized on graphene-coated glassy carbon electrode by a potential cycling between –0.15 and +0.95 V (vs. SCE) at a scan rate of 0.05 V/s, in aqueous solution  containing 1.0 M HClO4 and 1.0 mM monomer 1,8-DAN,. The adsorption of Cu2+ ions onto the P(1,8-DAN) thin film was caried out in 0.1 M Cu(NO3)2 solution at 80 oC, followed by electrochemically redution to metal Cu0 by applying -0.4 V. The obtained copper decorating poly(1,8-diaminonaphthalene)/graphene (Gr/P(1,8-DAN)-Cu) electrodes acted as a catalyst in the enhancement of electrochemical signal for the determination of nitrite. The linear voltammetric response to the nitrite concentration was observed by a square wave voltammetric technique in the range of 0.69 to 1.12 mM with a detection limit of 0.13 mM. The results open up the path for designing other nitrite sensing based on our novel approach.

The main thesis of article is the analyse of the Chinese contradictions on the characteristic and changes of contemporary epoch. PR China started at 2016 to 13. 5-year socio-economic plan in new “normal economy”. The Chinese GDP at 2020 should reach 80 bin yuan, it’s about 18,75 bin US dol. counted in purchase power of yuan. The slower economic growth and world financial crisis influenced on the social and political tensions in China and on the international area. Xi Jinping – leader of CPC declared at July 2016 in Beijing: “Marxism should be fundamental principle and guiding sign. Otherwise the Party can lose it soul and direction in the confrontation to the Chinese socio-economic development at 2016–2020.” Its demonstrated his deep anxiety with reference its future. Other questions of article are the influence of the socialist market economy on the socio-class structure of CPC, the changes of the class character of CPC, the main threats for China and perspective its development.

For the last 150 years there were several attempts to write down Ukrainian language with Latin alphabet, including the attempts of adopting several laws that took place after declaration of independence of Ukraine in 1991. But there were not practical and popularize. The main reason is that they haven’t kept the spirit of the Ukrainian language, some Cyrillic letter handed combination of several Latin letters and the same distorted sound (phonetics) of Ukrainian language. But the social processes that take place in Ukraine since the declaration of its independence, i.e. significant emigration of workers that counted in the millions, and also problems with communication with the families that stayed in Ukraine using modern computers and technologies which are equipped only with Latin keyboard without access to Cyrillic alphabet, call for a great need for a creation of the opportunity to use Latin alphabet to record the Ukrainian language, which would retain its nature and was easy to use. This article presents a new version of Latin alphabet for the Ukrainian language. It does not replace the Cyrillic alphabet – but a parallel alternative for it and for all other versions of the alphabet that are used to record the Ukrainian language. This alphabet I called “Ukrainka” in honor of Ukrainian ladies who represent the majority of our emigrants. “Ukrainka” is completely unified alphabet, without any disadvantages from their predecessors. The main idea is in replacing one letter of Cyrillic alphabet to exactly one Latin letter – a transliteration of 1:1, does not break and does not introduce any new rules in Ukrainian spelling and phonetics, thus saving the Ukrainian language. There are other advantages: – no change in letters, regardless of their position in the word; – the word written in the Cyrillic “Ukrainka” always looks the same (the same set of letters) and there are no several options to write the same word; – saved Ukrainian language peculiarity to soften the consonants – saved not only a soft sign but also an apostrophe as a dividing option for separating from certain sounds in the middle of a word; – for the letters Ж, Ч, Ш, it’s used letters that mean the same in other languages with the Latin alphabet, namely Ž, Č, Š, and for Є, Ю, Я, Щ picked up letters graphically similar as the above – Ě, Ŭ, Ă, Ş. The main element of this article is a table of characters, the description justifying their introduction and showing how to use in computers, as well as examples of different tests transliteration.

The change of the P-functionality in different organophosphorus compounds is an often occurring synthetic task. In this preliminary communication, we describe halogen-free, and hence environmentally- friendly ("green") transformations including the microwave-assisted conversion of phosphinates
to phosphinic amides, and vica versa, the transformation of phosphinic amides to phosphinates.
Building information modelling for airport facility management: the case of a US airport
Authors: Asare Kofi A B , Liu Rui , Anumba Chimay J
Published: March 2023

Facility management (FM) at airports involves the use of systems such as computerised maintenance-management systems (CMMSs). Currently, the integration of building information modelling (BIM) with CMMSs is yet to reach maturity, resulting in the inability to reuse BIM data produced prior to the operation and maintenance phase. The lack of accurate equipment data and its untimely handover contribute to failed CMMS programmes. The studied US airport had a low CMMS utilisation, resulting from a lack of equipment data from recent and old construction projects, and it also lacked an efficient process for acquiring, storing and exchanging asset data from construction into its CMMS. To address this, the airport sought solutions to reuse BIM data in the CMMS. Utilising a design science research methodology, this research proposed and tested a solution technology innovation comprising a BIM–FM integration framework and a structured workflow based on BIM and Construction Operations Building Information Exchange (Cobie) for FM data delivery into a CMMS. The proposed solution was tested on a real-world project at the airport, showing efficacy in providing the required equipment data in a timely and accurate manner as compared with the existing practice. The study provides practical evidence of application of BIM and Cobie in FM data delivery from a handover perspective.

Risk Management as a Dynamic and Continuous Process in the Life Cycle of a Typical Major Civil Engineering Project
Authors: Tshering Dawa
Published: March 2023

While many construction industries acknowledge the importance of risk management policies but hardly do they implement a defined technique in risk management. Many construction practitioners employ linear risk management process by applying risk mitigation process as and when risk occur. When project managers and practitioners ignore the application of risk management in real time projects, the implications are almost usually observed in the projects through forced variations, scope change and high uncertainties. In a complex and major civil engineering project, the risk exposure environment changes and shifts constantly due to external factors, changing objectives and other multiple dynamic variables. Quite often, initially planned risk mitigation targets do not generate intended outcome due to inadequate application of risk assessment process. For this reason, the risk and uncertainty management must be continuous, holistic and real time throughout the project life cycle from inception to completion. The ultimate goal of risk management plan is to achieve the project objectives in terms of cost, quality and time. Thus, risk management in complex and major civil engineering projects must be applied in real time, continuously and with utmost importance.

Research background. Despite clearly recognized links between increased body mass and increased risk for various pathological conditions, therapeutic options to treat obesity are still very limited. The aim of the present study is to explore the effect of low-molecular-mass collagen fragments obtained from the scales of Antarctic wild marine fish on rats’ visceral and subcutaneous white adipose tissue in a high-calorie diet-induced obesity model.
Experimental approach. The study was conducted on outbred rats, which were divided into 3 experimental groups: (i) control, consuming standard food (3.81 kcal/g), (ii) obese group, consuming a high-calorie diet (5.35 kcal/g), and (iii) obese group, consuming a high-calorie diet (5.35 kcal/g) with intragastric administration of low-molecular-mass collagen fragments (at a dose 1 g/kg of body mass during 6 weeks). Low–molecular-mass collagen fragments were obtained by a procedure that included collagen extraction from fish scales and enzymatic hydrolysis with pepsin. Apart from hematoxylin and eosin staining, fibrosis level was assessed by histochemical Van Gieson’s trichrome picrofuchsin staining, and mast cells were analysed by toluidine blue O staining.
Results and conclusions. Group treated with low-molecular-mass fragments of collagen exhibited decreased rate of mass gain, relative mass, area occupied by collagen fibre of both visceral and subcutaneous adipose tissue, and cross-sectional area of both visceral and subcutaneous adipocytes. Treatment with low-molecular-mass fragments of collagen reduced the infiltration of immune cells, number of mast cells and their redistribution back to the septa. This was also accompanied by a decreased number of the crown-like structures formed by the immune cells, which are markers of chronic inflammation that accompanies obesity.
Novelty and scientific contribution. This is the first study that reports the anti-obesity effect of low-molecular-mass fragments produced as a result of controlled hydrolysis of collagen from the scales of Antarctic wild marine fish in the in vivo model. Another novelty of this work is the observation that the tested collagen fragments not only reduce the body mass, but also improve the morphological and inflammatory parameters (decrease in the number of crown-like structures, immune cell infiltration, fibrosis and mast cells). Altogether, our work suggests that low-molecular-mass collagen fragments are a promising candidate for amelioration of some comorbidities linked to obesity.

In the modern world, innovations act as the main driver in all spheres of human life. It is innovations in conditions of limited resources and in an intensive type of economic development that become the driving force of economic and social development. Today, in economies oriented towards an innovative development path, the efficiency of the functioning of business entities is determined by their ability to implement progressive changes based on the achievements of scientific and technological progress. In this regard, the problem of the efficient use of scientific and intellectual capital, the expansion of conditions for the use of new technologies and the widespread use of innovations becomes relevant. In this regard, this article analyzes the existing methods for assessing the effectiveness of the innovation systems of the region. Approaches to the interpretation of efficiency, the definition of its types and criteria based on many features that synthesize various aspects of social relations have been studied. The effectiveness of various socio-economic systems based on the modification of qualitative determinants of development and methods for determining economic efficiency are analyzed. An approach is presented to determine it in the conditions of modern economic relations, taking into account regional characteristics. The main directions of efficiency are studied: scientific, social, economic, informational, ecological. A toolkit for determining the economic efficiency of regions is presented, which makes it possible to more objectively assess the degree of economic investment, which makes it possible to determine the strategy of the economic policy pursued at the regional level. In modern conditions, it is obvious that innovations require investments, and in most cases not small ones that need to be implemented now, and the effect may not be reflected in the very near future. For this, it is necessary to manage innovation activity, to know its effectiveness. With the successful management of such activities, it is possible to adjust and increase its effectiveness. Taking into account the foregoing, this article presents methods for determining the effectiveness of innovative systems in the region
