Abstract
The aim of the article was to investigate the effect of sea buckthorn juice addition on the growth of microbial cultures in growth medium and juice mixtures. Pure sea buckthorn juice was found to inhibit the growth of all 11 monitored microbial cultures. Lactobacillus plantarum CCM 7039, Lactobacillus plantarum K816, Lactobacillus brevis CCM 1815 and, to a lesser extent, the probiotic strain Lactobacillus rhamnosus GG, grew in a growth medium containing a 25 % addition of sea buckthorn juice. Lactobacillus plantarum K816 and Lactobacillus brevis CCM 1815 grew better in this mixture than in pure growth medium. Moreover, we focused on finding a suitable ratio of sea buckthorn and apple juice for Lactobacillus plantarum CCM 7039, leading to malolactic fermentation, which results in an increase in the pH value and an improvement in the sensory properties of juices. The intention was to incorporate the highest possible addition of sea buckthorn juice while maintaining the viability of Lactobacillus plantarum CCM 7039 for malolactic fermentation to occur. The best results were achieved using 40 % sea buckthorn juice. Practical application of the results points to the possibility of preparing a fermented fruit beverage and a dairy product containing sea buckthorn juice. The results of this work extend the current options of sea buckthorn juice processing increasing thus the consumption of healthy juice.

Abstract
The assessment of environmental radioactivity much relies on radionuclide content in soil. This stems from the significant contribution of soil to both external and internal exposure to ionising radiation via direct emission of gamma radiation and soil-to-plant radionuclide transfer, respectively. This motivated us to carry out a systematic research on the radioactivity of soil in Croatia to obtain relevant data that can be used as a basis for understanding the related effects of geomorphological, biogeographical, and climatological properties of the environment. We collected samples of the surface layer of uncultivated soil (0–10 cm) at 138 sites from all over the country and measured them for radionuclide activity concentrations by means of high-resolution gamma-ray spectrometry. This resulted in radioactivity maps containing data on activity concentrations of representative radionuclides in the environment. In this paper, which is the first in our two-part presentation, we focus on the naturally occurring 232Th and 238U decay chains and their correlations with the diversity of Croatian regions. For both of the chains, activity concentrations were the highest in the Dinaric region, the lowest in the Pannonian region, and intermediate in the Adriatic region. Relatively high concentrations of 226Ra in the soil of the Dinaric region implied a possibility of an enhanced emanation of its progeny 222Rn into the air. Activity concentrations of 210Pb were additionally elevated in areas with dense vegetation, most probably due to an atmospheric deposition of airborne 210Pb onto the surface of plants and their eventual decomposition on the ground.
Application of a new in situ calibration technique for gamma spectrometry and comparison of in situ and laboratory measurements

Published: April 2021

Abstract

In situ gamma ray spectrometry was developed to quickly measure large areas of land following nuclear accidents. However, a proper calibration of detectors for in situ measurements is a long and complicated process. One tool designed to make this calibration quick is the InSiCal software. We compared 5,000 s in situ measurements with two different HPGe detectors calibrated using the InSiCal software and laboratory measurements of samples collected at the same locations. Our findings suggest that in situ gamma spectrometry using InSiCal software can provide reasonably accurate data, but some improvements are needed.
Unusual aetiology of a type 2 myocardial infarction: a case-based review
Authors: Toma David , Toma Tania-Emima , Bologa Cristina , Lionte Cătălina 
Published: April 2021

Abstract
Organophosphate pesticide (OP) poisoning is quite common and can cause cardiovascular complications and even direct myocardial injury. However, no guideline has included an acute poisoning as a potential cause for a type 2 myocardial infarction (MI) so far. Here we present a case of a 61-year-old woman brought by ambulance to emergency department one hour after accidental ingestion of an unknown quantity of a solution she used against flea infestation. The patient presented with dizziness, myosis, excessive sweating, hypersalivation, sphincteric incontinence, muscle fasciculation, tremor of the extremities, pale skin, alcoholic and pesticide breath odour. Even though we had no guidelines to fall back on, we successfully treated the patient with low-molecular-weight heparin, antiplatelets, statin, diltiazem, antidote therapy, and supportive care. Physicians should be aware that OP poisoning can induce type 2 MI as a complication within a few hours since exposure, and emergency management should always include close cardiac monitoring.
Characteristics of work-related COVID-19 in Croatian healthcare workers: a preliminary report

Published: April 2021

Abstract
Healthcare workers (HCWs) are considered to run a higher occupational risk of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and develop coronavirus disease (COVID-19) than the rest of the population. The aim of this study was to describe and analyse the characteristics of work-related COVID-19 in Croatian HCWs. Study participants were HCWs who contacted their occupational physician between 1 May 2020 and 12 November 2020 with a request for the registration of COVID-19 as an occupational disease. All participants filled out our online Occupational COVID-19 in Healthcare Workers Questionnaire. The study included 59 HCWs (median age 45.0, interquartile range 36.0–56.0 years). Most (78 %) were nurses or laboratory technicians, and almost all (94.9 %) worked in hospitals. Hierarchical cluster analysis revealed three clusters of COVID-19-related symptoms: 1) elevated body temperature with general weakness and fatigue, 2) diarrhoea, and 3) headache, muscle and joint pain, anosmia, ageusia, and respiratory symptoms (nasal symptoms, burning throat, cough, dyspnoea, tachypnoea). Almost half (44.6 %) reported comorbidities. Only those with chronic pulmonary conditions were more often hospitalised than those without respiratory disorders (57.1 % vs. 2.5 %, respectively; P=0.001). Our findings suggest that work-related COVID-19 among Croatian HCWs is most common in hospital nurses/laboratory technicians and takes a mild form, with symptoms clustering around three clinical phenotypes: general symptoms of acute infection, specific symptoms including neurological (anosmia, ageusia) and respiratory symptoms, and diarrhoea as a separate symptom. They also support evidence from other studies that persons with chronic pulmonary conditions are at higher risk for developing severe forms of COVID-19.

Authors: Benkő Melinda , Antypenko Hlib , Losonczy Anna Kornélia 
Published: April 2021

Abstract
Food markets provide a continuous urban function at the centre of urban quarters, and their structures are an important component of the local identity. Therefore, they could be crucial in the complex renewal process of a mass housing neighbourhood, indeed. The paper focuses on the contemporary markets within Budapest’s three large housing estates, in Újpest Centre, Békásmegyer, and Havanna, opened in 2018, 2019, and 2020, respectively. The research is based not only on the study of relevant literature, design documents, publications, fieldwork, but also on a survey conducted with three well-recognized Hungarian architects in order to understand and compare their views on the complex context beyond the urban and architectural solutions. The questions focused on the crucial or determining factors of the design process such as the budget, the main players, references, physical context (built and natural), social context, program, and technology. These public projects of varied scale were used for exemplary contemporary food market case studies from Budapest, in which the people involved took into consideration the existing social and material problems and the potential of the heritage of modern mass housing neighbourhoods.
Possible Relations between Brightest Central Galaxies and Their Host Galaxies Clusters and Groups
Authors: Samir R. M. , Shaker A. A. 
Published: April 2021

Abstract
The r-band of the Sloan Digital Sky Survey (SDSS) for 17,924 brightest cluster galaxies (BCGs) in clusters and groups within 0.02 ⩽ z ⩽ 0.20 are used to study possible environmental relations affecting the nature of these galaxies. We find a correlation between BCGs physical properties (the effective radius (Re
), absolute magnitude and central velocity dispersion (σ
0)) and their host groups and clusters velocity dispersion (σcl
). This type of relations suggests that the most massive groups or clusters host larger central galaxies. On the other hand, the σ
0/σcl
ratio as a function of σcl
is consistent with [10].

Authors: Zsido Kinga Emese 
Published: April 2021

Abstract
The number of enterprises, respectively their structure by fields of activity, influences the level of the national economy, so it is extremely important to know the “map” of economic agents in terms of evolution and level of competition by areas of activity. The purpose of this paper is to present in a descriptive way the evolution of the number and structure of active enterprises in Romania (by legal form and field of activity), as well as a comparative presentation of the situation of enterprises in Hungary and Poland. In all three countries, the total number of enterprises shows a continuous growth trend, but with significant differences in the growth rate, analyzed by areas of activity.

Abstract
The aim of this study is to establish the psychological characteristics of patients with diabetes. In the present study we included subjects with diabetes (n=60), and control group (n=62). In order to study the psychological characteristics of patients with diabetes, we have applied the following tests: Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), Strategic Approach to Coping Scale (SACS), Cognitive Emotion Regulation Questionnaire (CERQ), Young Schema Questionnaire (YSQ-S3), Attitudes and Beliefs Scale (ABS II). The results of this study outlined psychological characteristics of patients with diabetes which consists of neurotic, anxious personality with a high level of activity, dysfunctional coping strategies like: indirect action, antisocial action, aggressive action and catastrophizing, irrational thinking and few maladaptive cognitive patterns. The study highlighted the need to restructure the maladaptive cognitive schemes, irrational beliefs, dysfunctional coping strategies for people with diabetes with a psychological program in order to improve endocrine symptoms and increase quality of life.

Published: April 2021

Abstract
The aim of this study was to define the transcript expression of 12 genes, identify new polymorphisms in selected 2 genes and to estimate the association between the level of expression, gene polymorphism and litter size in sows. Two groups of sows were selected: 71 crossbred sows and 328 purebred sows. For transcript analysis endometrial tissue samples were collected, while blood was sampled for the purpose of DNA polymorphism analysis. For all animals data on litter size and weaned piglets were obtained. Transcript analysis of 12 genes was performed in the uterine endometrium of sows in the luteal and follicular phases. Eight out of 12 genes showed higher mRNA expression levels during the luteal phase (AREG, FABP3, IL1A, ITGAV, ITGB3, NMB, OPN, RBP4). In turn, higher expression levels in the follicular phase were observed for 4 genes (IL1B, PPARG, S100A8, SELL). Analysis of six new polymorphic sites within the OPN and AREG genes revealed the highest heterozygosity for OPNe6_Knoll, OPNp3_617 and AREGe2_317 polymorphisms and the lowest heterozygosity in the AREGe3_561 locus. Association analyses concerning transcript expression levels of the 12 genes and the OPN and AREG genotypes in the two groups of sows showed a significant relationship between the IL1A, ITGB3 transcript expression and the OPNe7_603 genotype also between OPNp3_617 genotype and ITGB3 transcript expression. With regard to the litter size and the number of weaned piglets a significant relation with the OPNp3_617, OPNe6_462 and AREGe2_317 genotypes was observed only in the purebred sows. Transcript expression of the genes encoding osteopontin and amphiregulin in the uterus of the sows affect reproductive traits by preparing the uterus for embryo reception.

Abstract
The study herein evaluated the effects of dietary supplementation with different yucca (Yucca schidigera) extract levels on rearing water quality, growth performance, protein utilization, hematological and immunological status, and economic benefits of cultured European seabass (Dicentrarchus labrax) juveniles. Yucca extract (YE) was incorporated in an experimental diet at levels of 0, 0.25, 0.50, and 1 g YE kg−1, and offered to fish reared in 70-L glass aquaria (15 fish per aquarium; three replicates each). Dietary YE supplementation significantly (P<0.05) decreased ammonia-nitrogen levels in water. Compared with the control, groups fed 0.50 and 1 g YE kg−1 diets showed improved growth performance (by 26.02% and 36.98%, respectively) and protein efficiency ratio (by 31.39% and 37.29%, respectively). In addition, hematological parameters (red blood cells, hemoglobin, hematocrit, white blood cells and neutrophil) and innate immune parameters (globulin fractions and lysozyme activity) improved with increasing dietary YE levels. Growth, hematological, and immunological parameters increased with a polynomial second-order regression models, with curves peak close to 1 g YE kg−1 diet. The cortisol level decreased significantly (P<0.05) with increasing dietary YE levels. The groups fed the 0.50 and 1 g YE kg−1 diets generated significantly (P<0.05) higher revenue than groups fed the 0.25 g YE kg−1 and the control diets. The using of YE is recommended as a dietary feed additive at a level of 1 g kg−1 for reducing the environmental footprint of fish protein production, accelerating growth, and improving health status of cultured seabass in a short-term feeding period.
Digital City as a Metaphor for New Experiences of Reality
Authors: Komatina Dragan F. , Jašarović Ema Alihodžić 
Published: April 2021

Abstract
In the era of already spent utopias and ideas about the city the experience of the city is transformed into a new perceptual grammar that is a consequence of the new virtual reality. With the revolutionary computerization of architecture a new architectural discourse was created that enabled virtual one – cyberspace, producing a new experience of transposed reality. The concept of a digital city does not exist without a virtual community, which on the other hand problematizes the issue of digital city ethics, bearing in mind that its use is conditioned by technical and technological possibilities, which are still not available to everyone. Digitalization of space communicates the newly created virtual dialogue between the user and space, outside of his physical and sensory experience and interaction with space, thus agreeing to the digitalization of the experience of space. By creating a new reality and a new era of the utopia of virtual architecture and virtual city, a new, cyberidentity of city was produced. Identity digitization policies in this regard will consciously use methods to promote virtual values, digitizing all aspects of identity, heritage, and even memory, and memory values of the city, producing a new, virtual identity, which largely leads to mutation of its original – existing – built identity. In this way, cities are positioned and valued in relation to the degree of their digitized representation, i.e., the extent to which their digitized identity is present and visible in cyberspace. The digital transition is one of the priorities of the “smart city” concept, which indicates that the future of cities is directed towards their digital transformation.
Transylvanian Autonomy: Romanian and Saxon Models between the Two World Wars
Authors: Miklósné Zakar Andrea 
Published: April 2021

Abstract
The establishment of Greater Romania between 1918 and 1920 induced several social, political, administrative, and economic problems in the new state. The differences between the history and traditions of the diverse parts of the country impeded the unifying centralization efforts. The peculiarities of Transylvania and the issue of the autonomous Transylvania appeared in the writings of several intellectuals and politicians between the two world wars. In addition to the Hungarian plans, Romanian and Saxon ideas were also born, emphasizing the importance and possibilities of Transylvanian autonomy. The study tries to present some aspects of the special regionalism of Transylvania between the two world wars and to analyse some Romanian and Saxon models.
Territorial Interrelation between Innovation and a Number of Social/Infrastructural Indicators in Central and Eastern Europe (V4 + Romania)
Authors: Szilágyi Ferenc , Debrenti Edith 
Published: April 2021

Abstract
The study examines the performance of the Visegrád countries and Romania. As an indicator of innovation performance, we used the number of researchers measured from the active population. Due to the large variations in the size of the administrative-territorial units, the use of this ratio seems more adequate than using absolute values. The innovation indicator and the other indicators used are included in the analysis database in a regional breakdown. All indicators have an overview map of the entire large region for the purpose of establishing the territorial profile. In the course of the statistical investigation, each indicator was individually compared to the innovation index.
Taxation and Humans in the Age of the Fourth Industrial Revolution – Financial and Ethical Comments
Authors: Cseh Balázs , Varga József 
Published: April 2021

Abstract
In our study, we focused on the fourth industrial revolution, which is the revolution of machines at the same time and which affects the world of worthy human work significantly. Let us examine the reasons behind the machine wrecking in the modern era and the technophobia, the negative and positive outcomes of additional spare time, and the state of unemployment. We touch upon the historical antecedents of modern machine wrecking and its present situation. We briefly draw possible alternatives as regards the subthemes. In this study, ethics is ascribed a focal attention since we approach the trends that affect the world of work and have an economic significance in the context of the fourth industrial revolution. We examine the process of Industry 4.0, which has led to a significant transformation of production processes from the aspect of taxation – for example, how the automation of the production processes influences the transformation of the tax system, where humanity is in the changing financial world, or which aspects of the tax system change in the age of the Fourth Industrial Revolution.
Wrested from Oblivion: General Ludwik Mierosławski’s Strategy Game Rediscovered
Authors: Heyn Oliver 
Published: April 2021

Abstract
During the first half of the 19th century, liberal and nationalist uprisings erupted in all corners of Europe. While militant revolutionaries fought against restorative monarchies for more tolerant legislation or even full national independence, their countries slid into turmoil. In this European struggle, which set parts of Germany, Poland, France and Italy aflame, Ludwik Mierosławski (1814–1878) was one of the key insurgents. Besides being a keen partisan of Polish independence, Mierosławski enjoyed thorough military training and proved himself an astute theoretician of military strategy. It might be argued that he was probably one of the most inventive minds of his time, creating among other things an early tank vehicle and a bulletproof knapsack that could be used as a shield.
This article brings a hitherto unknown invention of Mierosławski to light: A strategy game depicting military maneuvers on an abstract map. Defying complicated rules and adhering to pure simplicity, the game was both fast-learning and captivating. Moreover, contemporary critics praised its way of introducing players to the fundamentals of strategic thinking and military geography. Several matches were even played at the French military academy at St. Cyr in 1858. The extensive research of this article not only reveals the background of Mierosławski’s invention but also his methods of making the complete game public. The last chapter of this contribution contains a summary of the game rules, enabling the readers to bring this invention to life by themselves. In the end, the study of his game allows us to approach and discover Mierosławski’s ideas and ways of thinking, thereby shedding further light on this complex personality.
