Published: July 2022

Podstawowym celem pracy jest kontestacja rozpowszechnianego
i utrwalanego przekonania wskazującego, że opracowanie rozwiązania architektonicznego
o wysokich walorach użytkowych i estetycznych w ramach programu TBS jest mało prawdopodobne. Postawiona w pracy hipoteza zakłada, że realizacja taniego budownictwa wielorodzinnego noszącego znamiona rozwiązania o wysokiej jakości jest możliwa wówczas, gdy przyjęta strategia projektowa odwołuje się do syntezy odpowiednio dobranych paradygmatów modernizmu. Przyjęta w pracy metodyka polega na kreatywnej
i konsekwentnie ukierunkowanej korelacji odpowiednich warstw autorskiego rozwiązania architektonicznego ze wskazanymi poglądami wybitnych twórców. Ostatecznym rezultatem założeń wstępnych jest architektoniczny projekt koncepcyjny zespołu mieszkaniowego, w którym wysoka jakość rozwiązań jest pochodną strategii projektowej zakorzenionej w ponadczasowych tezach modernizmu. Najważniejszym wnioskiem z przeprowadzonej analizy jest przekonanie, że w ramach programu TBS, którego pryncypia są podporządkowane kryteriom niskich kosztów realizacji
inwestycji, istnieją realne możliwości kreowania rozwiązań architektonicznych o wysokich walorach użytkowych i estetycznych.
„My sword is science, my shield is work.” : Messages of the legacy of Vilma Hugonnai, the first Hungarian female physician in 2022
Authors: Czippán Katalin , Moravcsik Andrea
Published: July 2022

The Hungarian National Commission for United Nations Educational, Scientific and Cultural Organization (UNESCO) has proposed the commemoration of the 100th anniversary of the death of Vilma Hugonnai, the first Hungarian female physician, in 2021, in a joint commemoration with UNESCO. After the positive decision of the General Assembly in November 2021, the Pre- sident of the Hungarian National Commission for UNESCO proposed to the Union of Hungarian Women the coordination of a joint commemoration of the “100th Anniversary of the Death of Vil- ma Hugonnai (1847-1922), the first Hungarian doctor”. With this commemoration, Vilma Hugon- nai’s work as a healer for families, her intellectual achievements, her enduring spiritual strength, her courage, her innovative and proactive approach and her spirit of sustaining women’s role in society as a value are to be presented as examples for present and future generations. The event is co-organised by the Hungarian Association of Midwives, the Semmelweis Museum and Archives of Medical History and the Professional Association of Hungarian Health Visitors. “She did not have an easy life, she had plenty of work besides her professional duties, she was a child minder, an advocate for children and women, and furthermore, she managed to publish a book. She translated the Anna Fischer-Dückelmann’s book from German, a family medicine book for women, and wrote the foreword to it – a copy of which I keep in the family heritage”, said András Lászlóné Radványi, great-niece of Vilma Hugonnai, at the inauguration ceremony of the Vilma Hugonnai Square in 2020 in Józsefváros (the square next to the External Clinical Block of Semmelweis University, is named after the first Hungarian female doctor). In this article, the life of Vilma Hugonnai will be analysed based on interviews with organisers, the objective being the exploration of the message and example of Doctor Hugonnai to the organisers 100 years later.
IT HAS POTENTIAL BUT…’ – EXPLORING UNIVERSITY STUDENTS’ EXPERIENCES AND PERCEPTIONS OF BREAKOUT ROOMS DURING THE COVID-19 PANDEMIC
Authors:   University of Nicosia, Savvidou Christine , Alexander Katarzyna ,   University of Nicosia
Published: July 2022

COVID-19 has created a dramatic and rapid transition to emergency remote teaching in higher education (HE) creating both new opportunities and challenges for lecturers and their students. As HE adapts to these new circumstances, there is a need for instructors to design and teach classes that support collaborative learning and increase opportunities for student interactivity. This article reports on an ongoing study exploring university students’ experiences and perceptions of using breakout rooms (BRs), a technical feature of many synchronous online platforms, as part of their online classes. Using a mixed methods research approach, 127 students, who were registered on English language courses at a university in Cyprus during Spring 2021, participated in the study. Findings indicate that students’ experiences and perceptions of breakout rooms during this period were impacted in five key areas: (1) emotional/affective, (2) moral/ethical, (3) social, (4) pedagogical and (5) technological. These findings suggest that students’ personal feelings, attitudes to online learning, sense of connectedness to their peers, expectations of the role and presence of the lecturer and issues relating to the technology, are all considered to be significant factors in their use of BRs. This study offers initial insights for educators who wish to use, modify and/or adapt synchronous online teaching to incorporate collaborative learning opportunities through breakout rooms. Keywords: higher education; synchronous online teaching; breakout rooms; collaborative learning; student experiences; COVID-19

This paper proposed an approach for obesity levels classification. The main contribution of this work is the use of boosting and bagging techniques in the decision tree (DT) and naïve Bayes (NB) classification model to improve the accuracy of obesity levels classification. This is achieved by introducing a boosting and bagging technique to further improve the recognition rate of obesity levels in the DT model, eliminating the correlated features, and eliminating the zero observations problem in the NB model. To validate the accuracy of the proposed approach, empirical evaluation was carried out using WEKA to determine the accuracy, precision, and recall. The results show that the DT classification model performs better in terms of accuracy and average precision. The proposed approach can help in software development for the classification of individuals with obesity

Fluida merupakan suati zat yang dapat bergerak serta mengalami perubahan bentuk secara terus meneru yang diakibatkan oleh tekanan dan tegangan geser. Pada sistem heat exchanger peran fluida sangatlah penting, hal ini berkaitan dengan kemampuan fluida dalam menyalurkan kalor pada sistem heat exchanger. Untuk menambah durasi interaksi kalor dengan sistem maka perlu ditambahkan vortex generator. Dengan adanya vortex generator maka akan memperlambat interaksi aliran dan mengubah aliran laminar menjadi turbulance. Untuk mengetahui performa pembentukan aliran turbulance dari masing-masing vortex generator, maka perlu dibuat suatu media visualisasi. Media visualisasi yang dibuat pada penelitian ini yaitu menggunakan water tunnel berbentuk pipa konsentrik. Pada penelitian yang telah dilakukan menunjukkan adanya perbedaan dengan teori Reynolds Number, dimana meskipun secara perhitungan aliran masih tergolong laminar namun dalam visualisasi yang dilakukan aliran yang terbentuk adalah turbulance. Hal ini dikarenakan adanya perbedaan kecepatan aliran tinta dan air, sehingga pada penelitian ini dilakukan kondisi yang ideal untuk tujuan visualisasi. Berdasarkan hasil pengujian maka hasil visualisasi terbaik pada variasi 1 yaitu spesimen twist 5/10, pada variasi 2 spesimen recoil 5/10, dan pada variasi 3 spesimen twist 5/10.

Wastewater is untreated water that has high amount of nutrients such as nitrate, phosphate, ammonium and chemical oxygen demand (COD). When it is discharged into watercourse, it affects human and aquatic biota. The application of photosynthetic bacteria is considered bio-friendly system than the conventional one. Hence, the present study investigates the effectiveness of robust strain of photosynthetic bacteria for nitrate removal under different concentrations of 85, 135, 190, 235 and 320 mg/L. Serial dilution techniques was used for the isolation of the bacteria. The results showed that three bacterial isolate were obtained and were both screened for nitrate reduction ability. The isolate was able to remove 91, 90, 71, 67 and 55% of nitrate at 85, 135, 190, 235 and 320 mg/L respectively. The bacteriochlorophyll of the isolate was detected at peak range between 689-710 nm. The morphological, physiological and biochemical characterization showed that the isolate was identified as Rhodopseudomonas sp. The nutrient removal yield of the nitrate under different concentrations was found to be at range of 0.01- 0.033 g-1 DCW g-1 NO3.- This study suggested that the strain could be used as an efficient bacterial candidate for the treatment of wastewater containing high amount of nitrate.

Published: July 2022

Blackberry (Rubus subgen. Rubus Watson) cultivar 'Čačanska Bestrna' has long been the most commonly grown blackberry cultivar in the Republic of Serbia, owing to its high adaptability to respective agro-environmental conditions. In recent years, in order to increase the production of biologically valuable food, the fruit growing technology has been directed towards the concepts of integral and organic production. Blackberry grey mould (Botrytis cinerea Pers.) is an economically significant agent of the disease, which during the ripening phase reduces fruit yield by about 30% each year. In this regard, the efficacy of the preventive and curative influence of foliar applied FitoBotryfun was examined for two consecutive years. Incidence of grey mould (degree of infection), morphometric traits (fruit weight and dimensions), chemical traits (soluble solids content, total and inverted sugars, and sucrose content) and fruit mineral nutrient content [macro-(Ca, Mg) and microelements (Fe, Mn, Cu, Zn)] were recorded. A high variability was found in the degree of infection between the different disease management practices (organic and conventional) and significant differences were found in the contents of sugars, Ca, Mg and Fe in the fruit. The variations over the years were observed for the same quality traits, except for fruit height. The results obtained suggest that the foliar application of FitoBotryfun during the growing season can be effective in reducing losses in the quality of blackberry fruit during ripening as well as negative effects of conventional control methods on human health and the environment.

Published: July 2022

In November 2019, virus-like symptoms resembling those caused by turnip yellows virus (TuYV) were observed in many canola crops across Serbia. In order to identify their causal agent, a total of 206 samples were collected and analyzed for the presence of TuYV, cauliflower mosaic virus (CaMV) and turnip mosaic virus (TuMV), using commercial double-antibody sandwich (DAS)-ELISA kits. TuYV was detected serologically in 91.75% of tested samples collected at 24 locations in all of seven inspected districts. None of the samples tested positive for TuMV and CaMV. Further molecular characterization based on the partial P0 gene sequences of seven selected ELISA-positive samples showed that Serbian TuYV isolates collected in 2019 shared low nucleotide diversity, and that they were closely related to previously identified Serbian cabbage and mustard isolates of TuYV. Phylogenetic analysis showed that TuYV isolates from Serbia were clustered within the TuYV/BrYV group. Moreover, nucleotide and amino acid sequence comparison of all TuYV isolates originating from Serbia, supported with a phylogenetic tree, indicated the existence of two virus subpopulations in Serbia. Further research should focus on determining the variability of TuYV population in Serbia, based on a whole-genome analysis that will contribute to a better understanding of the epidemiology of this pathogen, aiming at developing and implementing appropriate control measures.

Published: July 2022

Red clover (Trifolium pratense L.) is a meadow and pasture species in natural habitats and also a cultivated species used for animal nutrition. The aim of this research was the assessment of the diversity of 46 red clover accessions based on morpho-productive traits. The traits were investigated according to the UPOV descriptors for red clover-number of internodes, number of branches, stem length, stem thickness, middle leaflet length, middle leaflet width, green matter yield and dry matter yield. The principal components analysis (PCA) explained 74% of the variance of the standardized data and showed relationships between 46 red clover accessions and eight morpho-productive traits, associations among traits and performance of accessions. Among the determined Euclidean distances, the smallest value was obtained for the accessions Rotra and Titus (0.048), the largest value was 1.099 for a pair of NCPGRU2 and Čortanovci accessions, and the average value was 0.380. Two clusters of 46 red clover accessions were separated in the dendrogram based upon UPGMA (Unweighted Pair-Group Method with Arithmetic mean) for eight morpho-productive traits. The first cluster included two subclusters, while the second cluster contained four subclusters. The grouping of the accessions from the red clover collection by the UPGMA cluster analysis can be linked to the geographical origin of the accessions: central and Southern Europe for three subclusters and northeastern Europe for one subcluster.
Functions of nickel in higher plants: A review
Authors: Kastori Rudolf , Putnik-Delić Marina , Maksimović Ivana
Published: July 2022

Nickel (Ni) is an essential microelement for higher plants and an important one for many other living organisms. It is present in every part of the biosphere. Higher plants have small requirements towards Ni for their optimal growth and development. That is why its latent and acute deficiencies in nature rarely occur. Soil and water pollution with Ni is a global issue. This is the reason special attention is paid to the effects of higher Ni concentrations on plants metabolism, their organic production, as well as on the possibility of using plants for phytoremediation of Ni contaminated habitats. Depending on the present concentrations, nickel may favourably, unfavourably or not affect the metabolic processes of plants at all (enzyme activity, photosynthesis, respiration, water regime, mineral nutrition, etc.), and thus the growth and development of plants. There are still many questions about the mechanism of Ni influence on the physiological and biochemical processes of plants. Therefore, we believe the presentation of the previous knowledge about the effect of Ni on plants' life processes can contribute to a better understanding of the biotechnical and ecological significance of Ni, and it can indicate further research directions in this field.
Pediatric pharmacokinetic considerations and implications for drug dosing
Authors: Jovanović Marija , Vučićević Katarina
Published: July 2022

Optimizing the dosing of medicines for pediatric patients in routine clinical practice and determining the dose for clinical trials is still a challenging task. Children differ from adults in their response to drugs due to inherent differences in pharmacokinetics and/or pharmacodynamics, and responses may also vary among pediatric patients of different ages. However, the greatest disparities compared to adult pharmacokinetic profiles are observed in children below 2 years of age. The maturation of the liver and the kidneys, as well as the variation in body composition, are considered to be the main sources of pharmacokinetic variability. Hence, besides specific pharmacodynamic features, understanding age-related changes in drug absorption, distribution, and elimination is fundamental for optimizing drug efficacy and avoiding toxicity. This paper summarizes the pharmacokinetic changes throughout the childhood, along with the effect of developmental changes on drug dosage calculation. In clinical practice, age and body weight-based dosing regimens are usually used. In spite of dosing recommendations based on age and/or body weight, variabilities in pharmacokinetics and pharmacodynamic response remain, implying a need to monitor patients and optimize the dosing regimen according to physiological characteristics, disease characteristics and therapy.
How to choose an appropriate drug dosage form for the treatment of respiratory infections in children: Facts and tips
Authors: Cvijić Sandra , Mirković Dušica , Krajišnik Danina
Published: July 2022

The treatment of respiratory infections in children requires special attention, since the paediatric population has rather specific characteristics and consists of heterogenous subgroups. In this context, the choice of a suitable drug dosage form is of particular importance, depending on the active substance properties, along with the age and general condition of a paediatric patient. The most commonly used pharmaceutical products for respiratory infections in children include oral, parenteral and inhalation dosage forms, although a large number of drugs are not available in a suitable dosage form and/or strength for paediatric age, leading to the frequent use of unauthorized drugs (i.e., unlicensed use). Other important issues that should be considered when choosing the appropriate paediatric dosage form and/or compounding procedure are related to the careful considerations of the pharmaceutical product composition (safety of excipients) and the choice of administration/dosing device in relation to a child's age. This paper provides an overview of paediatric dosage forms used in the treatment of respiratory infections in children, their benefits and limitations. The review includes examples of various pharmaceutical products, along with the considerations regarding administration/dosing devices. Specific characteristics of paediatric populations affecting the decision on the choice of age-appropriate paediatric formulation are also addressed.

Published: July 2022

The research aims to consider the nature of the influence of capital structure on the value of the corporations from the agro-food sector in Serbia. A panel regression analysis was used to test the hypotheses. The research covered the period from 2011 to 2018, and the sample consisted of 14 agro-food corporations whose shares are on the regulated market of the Belgrade Stock Exchange. The obtained results indicate that the capital structure has a statistically significant impact on the value of agro-food corporations and that the profitability of investment projects determines the nature of that impact. Consequently, the financial managers of agro-food corporations must consider the decision on the choice of capital structure as one of the key issues in the process of generating and increasing the corporation value.

The research was conducted on consumers and potential consumers of organic products in Serbia. In countries with average low incomes, knowledge of the organic products market is important because one of the often singled out characteristics of organic products is their premium price. Knowing the motives of potential consumers of these products and the characteristics that they value more gives the opportunity to improve this production. The research involved 496 respondents, older than 18, with different levels of education, marital status and other socio-demographic characteristics. The results showed that a healthy, quality product, which has no additives and harmful substances and has the best price-quality ratio with a clearly defined shelf life, are the basic factors for buying food products, the factors that most influence a positive purchase decision. The authors conclude that highlighting these characteristics in organic products can lead to further development of this market.

Authors: Jovanović Aleksandra , Atanasovska-Cvetković Aneta
Published: July 2022

Wine is not just a product of modern times. Wine, one of the oldest drinks in the world, was sold and inherited by ancient civilizations. Its importance is indicated by the regulation of wine in the Codes of ancient Mesopotamia and Roman law. Today, this agri-food product is sold on both the domestic and foreign markets, and it is indisputable that the production and sale of this product must be legally regulated. The authors of this paper, by analyzing the legal provisions of Roman law, the Law on Wine and the Criminal Code of Republic of Serbia, point out the importance of the existence and expansion of legal provisions related to wine and its producers and precise criminal law provisions in case of sale of wine produced contrary to legal regulations and contrary to the health of people who consumed the same. The stated purpose of the paper, in order to draw a conclusion about the importance of specifying legal provisions, was achieved by presenting the historical and positive legal regulation, using the historical method and comparative analysis.

The resource potential of the agricultural sector in Kosovo and Metohija is not sufficiently used, but there is certainly a need for agricultural production, as one of the primary activities, in places inhabited by non-Albanians. The aim of this paper is to analyze the development and potential of organic production in Kosovo and Metohija. For the purposes of this paper, an original questionnaire was formulated, based on when a direct survey conducted in July and August 2021 was conducted. Also, the owner of the only agricultural cooperative "Zubin Potok" in this area, was interviewed. The research showed that a more than thirty/four percent (34,7%) of respondents answered that they plan to expand production, good part of the respondents (23,3%) pointed out that they are interested in a some kind of education if it would be organized by professionals, while more than 90% of respondents involved in organic production said it would mean some form of subsidy or local or international aid. The authors point out that for the development of organic production in Kosovo and Metohija, it is necessary to provide financial support to farms, but also to build a stable market of organic products, which would contribute to the stability and competitiveness of this food production system.

The aim of this paper is to identify key human resource management activities in domestic agricultural enterprises and their scope, as well as accompanying problems. The research used a quantitative method, ie. a written structured survey was conducted via the Internet. The survey included 64 companies, and 29 or 43% responded. The results of the research show that domestic agricultural companies mainly carry out human resource management activities. In 17% of companies, a professional manager is hired, while in most directors they are superior to employees. Furthermore, the research found that most attention is paid to rewarding, motivating, training employees and managing safety at work, while job evaluation, socialization, cooperation with educational institutions and measuring employee satisfaction are of secondary importance. Personnel problems such as low motivation, work discipline, disturbed interpersonal relations, employee turnover, engagement of seasonal workers and lack of interest in training were expressed. An effective personnel policy can prevent staffing problems and improve productivity. We advise companies to consider investing in a quality manager, who would deal exclusively with human resources.

This paper diagnoses the determination of Covid-19 on economic and social aspects in Indonesia. Panel data collected from 34 provinces in Indonesia for the 2020-2023 period supports the quantitative method. Three analyzes (Spearman, Kendall, and Pearson) were used to measuring the relationship and its partial effect. Research findings indicate that Covid-19 cases have a negative impact on labor productivity , migration, domestic violence, and sexual harassment. From other results, per capita spending , well-being, unemployment, and poverty actually increased when there was a surge in Covid-19. For the Spearman rho correlation, with a degree of 1 percent (p < 0.01), there is a significant effect between capita spending on well-being, per capita spending and well-being on migration, and poverty on labor productivity. Tested by Kendall's tau and Pearson, the Covid-19 tragedy positively affected per capita spending, well-being, unemployment, poverty, and mortality, but labor productivity, migration, domestic violence, and sexual harassment were negatively affected by Covid-19. The partial probability level (p < 0.05 and p < 0.01) reveals a significant effect of per capita spending on well-being, migration on per capita spending and well-being, and poverty on labor productivity. Although per capita spending has a significant impact on well-being (5 percent confidence level), there is a slight difference from the Pearson test, where with a tolerance limit of 1 percent, poverty affects sexual harassment significantly. Covid-19 has taught many things, so that humanity does not disappear with conditions that seek peace. Policy makers need to schedule a more inclusive national and regional resilience system.
