Authors: Lazarević Jovana
Published: July 2022

Implementation of contemporary information technology provided banks with the possibility to communicate with clients through mobile banking. To improve this service quality, banks must monitor and analyse components that determine clients' intention to communicate with their bank through this channel. The goal of the paper is to identify key determinants of clients' intention to use mobile banking through empirical research conducted on a sample containing 196 clients. The paper analyses effects of the perceived usefulness and ease of use as the main components of the TAM model, by expanding the same with two more components: trust and credibility. By processing the data in SPSS software research obtained the results that all observed components, except trust, influence clients' intention to use mobile banking. The obtained results expand existing scientific knowledge in the contemporary banking communication research area and provide valuable knowledge for improving banking services quality.

How to recognize and treat herpes zoster infection?
Authors: Perić Jelena
Published: July 2022

Herpes zoster (HZ) is a common, infectious vesicular dermatosis caused by the reactivation of the varicella-zoster virus (VZV). It is a common clinical problem, especially in people over 50 and immunocompromised patients. Treatment of HZ consists of antiviral drugs, analgesics in the control of acute pain and adequate topical therapy that prevents the occurrence of secondary infection and promotes healing process. This paper presents the most important information related to the etiology and pathogenesis of HZ, epidemiological data and so far known risk factors, the spectrum of clinical manifestations and methods used in the diagnosis of this disease. Therapeutic modalities used in the treatment of HZ and accompanying complications are especially presented, and the need for the timely introduction of antiviral therapy is emphasized, as well as the importance of preventive vaccination of older age groups. Herpes zoster, due to its frequency and associated complications, is a significant public health problem. Due to the global increase in the number of people with compromised immune systems, whether due to age, disease or immunosuppressive therapy, there has been a significant increase in population risk for HZ and postherpetic neuralgia as the most common complication of this disease. For that reason, as well as due to the possible role of HZ in the development of vasculopathy, strokes and heart attacks, experts strongly recommend prevention of HZ by comprehensive vaccination of the elderly.
Acute tonsillitis and acute pharyngitis
Authors: Sotirović Jelena
Published: July 2022

Acute tonsillitis and pharyngitis are common diseases in clinical practice. Uncritical use of antibiotics has led to an increasing problem of antibiotic resistance. On the other hand, it is of great importance to correctly diagnose and timely treat bacterial tonsillopharyngitis in order to prevent complications. The aim of this paper was to review current guides and published papers in the professional literature related to diagnostics and therapy in children and adults, with the aim of their greater implementation in clinical practice. Acute tonsillopharyngitis is far more often - a viral infection, less often - a bacterial infection. In the differential diagnosis of these entities, the combination of clinical scores and rapid test for group A streptococcus is of the greatest importance. According to individual clinical assessment, microbiological analysis of throat swabs and laboratory blood tests may also be important. Viral tonsillopharyngitis is treated symptomatically. In the treatment of bacterial infections, penicillin preparations are the drug of choice. Treatment can be combined with a single dose of orally administered corticosteroid. The basic principle of treatment of acute tonsillopharyngitis must be a measure of clinical parameters, available diagnostics, general condition of the patient and his comorbidities.
High percentage of responders to acei as a significant success factor in the treatment of hypertension
Authors: Nedeljković Ivana
Published: July 2022

High blood pressure (BP) is the leading cause of premature death, with about 10 million deaths and over 200 million inabilities according to age. Despite treatment, this disability has increased in 40% of the population with hypertension (HTN). New recommendations for the treatment of HTN emphasize the importance of improving BP control where, for majority of patients, the best approach is to use 1 or 2 drugs with a simple algorithm. The inhibitors of angiotensin converting enzyme or angiotensin receptor blockers (ACEI or ARB) are the first line drugs alone or in combination with calcium channel blockers (CCS) and/or diuretics. We analyzed the treatment of HTN, with a focus on the use of cilazapril as an effective, long-acting ACEI. Cilazapril has shown efficacy in a single dose and good tolerability as monotherapy but also in combination with hydrochlorothiazide in all hypertensive groups as well as in special subgroups of patients such as the elderly, patients with impaired renal function, heart failure patients, chronic obstructive pulmonary disease. Dose titration and addition of diuretics lead to optimization of BP control and a high level of responders, which directly reduces the risk of adverse cardiovascular (CV) events.
The place of diuretics in hfref therapy according to the guidelines of European associations for the treatment of acute and chronic heart failure
Authors: Čanković Milenko
Published: July 2022

Heart failure is a clinical syndrome which can be manifested by structure and/or functional heart abnormality (LVEF is < 50%, pericardial cavity dilatation, E/E'> 15, moderate to severe hypertrophic cardiomyopathy and/or aortic valve stenosis or regurgitation) corroborated by elevated natriuretic peptides and/or objective indicators of pulmonary or systemic congestion. Based on a research data of hospitalized patients with heart failure, it is registered that the most frequent form is HFrEF, in 50% of the patients, whereas HFmrEF and HFpEF is registered in the other 50% of the patients. Today, the most common cause of heart failure is coronary artery disease. Prognosis of the patients with heart failure nowadays is much better when compared to the results of the first studies and researches. There are two types of heart failure based on the clinical presentation: acute and chronic heart failure. Heart failure is diagnosed based on the symptoms and/or signs of heart failure as well as objective indications of cardiac dysfunction. The goal of cardiac insufficiency with lowered LVEF treatment is the modulation of renin-angiotensin-aldosterone system (RAAS) and sympathetic nervous system. New group of medications, such as SGLT2, are introduced and recommended in treatment of heart failure. Diuretics have an essential role in treating patients with congestion. When treating with diuretics, the goal is to maintain euvolemic state by administering the lowest dosages of these drugs. Loop diuretics have the best effect on symptom reduction, congestion reduction and improvement in physical exertion. Beside loop diuretics, MRA is also a part of the therapy. The diuretic effect achieved by spironolactone and eplerenone is weak. These medications block aldosterone receptors. RALES study showed that administering spironolactone in patients with HFrEF leads to a significant morbidity and mortality reduction. In the past decade, there was a major breakthrough in the treatment of the patients with cardiac insufficiency by introducing modern medications which reduced mortality and the need for repeated hospitalizations caused by heart failure. Diuretic therapy has important role in treatment of patients with heart failure leading to reduction of congestion and better quality of life.

Quality of life (QoL) as a measure of subjective well-being is an important indicator in the everyday functioning of patients with psychosis spectrum disorders (PSD). The aim of this study was to explore the association between QoL and five symptom domains in outpatients with PSD. Our hypothesis was that negative and affective symptom domains would be associated with lower QoL. Socio-demographic and clinical data were collected from 68 participants who met the prerequisite for the current study - adult outpatients diagnosed with F20.x-29 (according to ICD-10), qualified by the attending physicians as stable. Their symptoms were assessed using the expanded version of the Brief Psychiatric Rating Scale (BPRS-E) on the basis of which five symptom domains were quantified: positive symptoms, negative symptoms, affective symptoms (anxiety/depression), activation and disorganization. QoL was measured with the ten-point Recovering Quality of Life (ReQol) scale. Mean age (SD) of the sample was 43.3 (11.0) years, and 60.3% of participants were male. ReQoL mean (SD) score was 25.4 (8.4) and BPRS-E mean total score was 1.9 (0.5). Regarding the BPRS-E and QoL score differences between males and females, educational level or marital status were not observed. Linear regression analyses showed that two out of five symptom domains were significantly associated with ReQoL: Affective domain (b coeff.=-.717, p<.001) and Negative symptom domain (b coeff.=-.299, p=.001). The present study of real-world clinically stable patients with PSD demonstrated that affective symptoms (depression/anxiety) had the strongest negative association with QoL in comparison with other symptom domains. This information could be useful for clinicians who should try to alleviate distress in order to improve the PSD treatment outcome.

Stress is present in our everyday lives and it is considered to be the driving force of evolution. Anxiety, chronic worries and panic attacks are the most common consequences of long-term and exhausting stress. The most significant fundamental contribution that is crucial for the development of the modern concept of stress was made by Claude Bernard who proposed the theory that the body was constantly maintaining a stable and well-balanced internal environment or "milieu interieur". Maintaining the internal environment constant was defined as homeostasis by Cannon who proposed two maintenance mechanisms - through negative feedback from the autonomic nervous system and through sensory organs. Hans Selye proposed stress as non-specific strain on the body, caused by an altered body function which is followed by the release of stress hormones. He named this process the general adaptation syndrome which had three stages: alarm reaction, initial phase exhibiting "fight or flight" response; resistance, when body is getting used to being stressed, and exhaustion, when resistance to stress is gradually decreased and collapses. Hans Selye was the first to coin the term "heterostasis" representing the procedure by which a new stable state was achieved by the activation of physiological adaptive mechanisms. Lazarus highlighted emotions as an important factor in behavior in response to stress and provided a description of various reactions to stressors. He emphasized the process of cognitive assessment as a mediator in dealing with stressors - how a person imagines or evaluates an event in order to understand stress reactions in people. Eustress, considered to be positive stress leads to toned emotions, motivation and focused energy, while distress, negative stress, occurs after prolonged stress that exceeds our ability to deal with it. Distress causes anxiety or withdrawal (depression and anxiety), and is accompanied by unpleasant feelings and reduced work ability leading to mental and physical illnesses.

In a view of important functions of glutathione transferase omega (GSTO) class in redox homeostasis and innate immunity, it was proposed that interindividual differences in COVID-19 clinical manifestations might be affected by GSTO1 (rs4925) and GSTO2 (rs156697) polymorphisms. To assess the potential association of these polymorphisms with biochemical, coagulation and inflammatory laboratory parameters in the group of mild and severe COVID-19 patients. GSTO1 and GSTO2 single nucleotide polymorphisms were determined by qPCR in 251 samples of COVID-19 patients. Biochemical, coagulation and inflammatory laboratory parameters of COVID-19 participants were procured from routine laboratory practice on the day of admission. Polymorphisms of GSTO1 and GSTO2 affect laboratory biochemical profile of COVID-19 patients. GSTO1*C allele was associated with increased levels of C-reactive protein (CRP) (p=0.035), interleukin-6 (IL-6) (p=0.047), D-dimer (p=0.014) and lactate dehydrogenase LDH (p=0.002), whereas GSTO2*G allele was associated with CRP (p=0.033). COVID-19 patients homozygous for variant GSTO1*A allele and GSTO2*G had the highest levels of serum Fe (p=0.019, p=0.052, respectively). Our findings regarding the influence of GSTO1 and GSTO2 polymorphisms on inflammation and coagulation parameters might be of clinical importance. In future, these findings could aid in a more personalized approach for better recognition of patients prone to thrombosis and excessive immune response.

Published: July 2022

Modern society shifts its focus to the security of the individual, as the basic unit of society, in all spheres of his life. The aim of this study is to present the results of research on the subjective feeling of safety of employees in the gaming industry in Serbia. The results showed that almost half of them feel insecure in their workplace. Analysis of the results of research tells us that the socio-demographic characteristics of subjects, such as sex, age structure, but also the Serbian region in which they live, and also if they belong to the student population, have an impact on their perception of the level of safety in the workplace. Other socio-demographic characteristics of an individual which have been studied have shown no statistical significance. Stress in respondents who feel very insecure in the workplace increases most when there is a physical conflict with someone or a major material loss. A linear correlation between indicators of stress and feelings of safety in the workplace was confirmed. The obtained results can be used to improve the safety situation at workplaces where money and people are handled, but also to take preventive measures in order to reduce the level of risk.
Economic and geopolitical aspect of the EU-China bilateral relations

Published: July 2022

The expected economic growth of the EU27 and China by 2025 will lead to a further increase in the share of the Chinese economy in world GDP and the overtaking of the EU economy in 2022. The main contribution of this paper is the presentation and analysis of IMF projected GDPs for China and the EU27 in the period 2020-25, and assessing the impact of divergent GDP growth trends of the two economic giants on the further development in their bilateral relations. Namely, since the change in the global economic position causes geopolitical consequences, it is clear that the very expectation of such trends influences the decisions of political and economic actors today - such as the signing of the investment agreement between Brussels and Beijing, despite Washington's opposition. The EU's response to China's growing influence could be an attempt to mitigate Beijing's strategic challenge by creating a stronger transatlantic partnership, but it is uncertain that Washington will be willing to offer significant concessions to Brussels. An alternative scenario could involve strengthening the EU's "strategic autonomy", which would imply an attempt at a more independent geopolitical positioning, which would enable better relations with China and easier access to the country's huge market. The EU, the world's largest trading bloc and the largest trading partner of as many as 80 countries, will find it difficult to come to terms with its subordinate role in Sino-US competition and will remain focused on exploring synergies with both powers.
The need and limitations of media literacy and critical opinion in the age of supervisory capitalism
Authors: Baltezarević Borivoje
Published: July 2022

The paper discusses the issue of modern society that functions mainly through new technologies. It points out the misconception that the Internet has provided safe and unlimited access to the world of knowledge and information and new modalities of creative expression. Time has shown that the use of modern technologies has led to the creation of new business models that are defined as surveillance capitalism, the emergence of which indicates the negative aspects of social media. Surveillance capitalism involves overseeing and compromising the privacy of the individual through the trade of personal data. The answer to this phenomenon is the potential role of critical thinking and media literacy. Critical thinking and media literacy are viewed in the context of national strategies and the individual aspect, while identifying existing potentials and constraints. Keywords: surveillance capitalism, media literacy, media education, critical thinking.

Authors: Vuković Boško
Published: July 2022

Conquering the new technologies for coal purification in the world has enabled the exploitation of coal deposits with similar characteristics as the subject locality, which until a few years ago were not profitable or even "forgotten". In order to exploit such deposits, more systematic research and testing of useful raw material base as a thermal energy fuel is needed [1]. Considering all that, the Gacko Mine and Thermal Power Plant, as the research holder, started drafting the Project of Detailed Geological Explorations on the return coal zone with a clear goal to define the quantities and quality of coal, i.e. obtaining the clear parameters on thermotechnical properties of combustible coal. On the basis of the Exploration Project, the detailed geological explorations of the "return coal zone" were performed and the exploration results served as a basis for the analysis of coal refining possibilities and possible reconstruction projects on the boiler system of the Gacko Thermal Power Plant.

Published: July 2022

Natural resources are limited and uncontrolled exploitation can have negative effects on the environment. It is necessary to find approach of their sustainable use. Sustainable development is the framework for defining strategies of continuous state and social progress, without harm to the environment and natural resources essential for human activities in the future. Model that regulates sustainable use considers strategies and legal regulations for exploitation of natural resources and energy. Goal is to ensure the sustainable use of natural resources at national and global level. Sustainable use of natural resources is directly related to environmental protection. Also, the preservation of the working and living environment is related to the degree of economic development and the level of education of the population about the importance of a healthy environment and the way of its preservation. Accelerated technological development leads to an improvement in the quality of life in all spheres of human activity, but in parallel, it creates the possibility of greater environmental degradation. Therefore, it is necessary, within the goals of the development policy of the society, to include the correct criteria that will contribute to sustainable development. Thus, we contribute to preserving the environment and balance of natural ecosystems.

The importance of determining the relationship between poorly recorded and archived contracts, decisions, opinions and instructions in relation to the introduced form of archiving in agricultural enterprises in Republic of Serbia
Authors: Stanojević Slobodan , Jeremić Dejan
Published: July 2022

Emphasizing the importance of establishing the link between poorly archived 4 forms of documentation in relation to the introduced form of archiving in agricultural enterprises in Serbia is one of the important issues in the movement of documentation in these companies. The authors analyzed 4 forms of documentation, namely: contracts, solutions, opinions and instructions on archiving in relation to the two forms of archiving documentation in companies (a new way of archiving-electronic and classic way of archiving documentation). The focus of the research of the authors of this study was the question of discovering a possible connection between poor record keeping, i.e. poor archiving of documentation in an agricultural company and the established form of archiving in the mentioned companies. The authors conducted research in 144 agricultural enterprises, and the results they obtained indicate that much fewer errors occurred in the case of electronic archiving of documentation (about 100% fewer errors) compared to classical archiving in agricultural enterprises.
Foreign versus local control of Spanish private subsidiaries and modified audit opinions
Authors: Gill-de-Albornoz Belén , Rusanescu Simona
Published: July 2022

This paper studies the relation between foreign control and the likelihood of receiving modified audit opinions (MAOs) by private subsidiaries. To further analyze this relation, we partition MAOs based on their underlying reason: GAAP violations; opacity; and uncertainties, including going concern (GCUs) and other (non-GCUs). We observe a significantly greater incidence of MAOs in subsidiaries owned by foreign groups than in those with a local parent company. This result is mainly driven by opacity related MAOs. The evidence of a higher incidence of GAAP violation and non-GCU related MAOs in foreign owned subsidiaries is inconclusive; and MAOs related to GCUs are significantly less frequent in subsidiaries of foreign groups. In contrast to the results found in the public setting, our findings suggest that foreign control in the private setting is associated with more opaque companies. This study contributes to a better understanding of the effects of foreign direct investment (FDI) in the host-country, at the company level.

En este trabajo se estudia la relación entre el control extranjero y la probabilidad de recibir opiniones de auditoria modificadas (OAMs) en una muestra de subsidiarias españolas no cotizadas. Además, para analizar con mayor detalle esta relación, clasificamos las OAMs en cuatro tipos, en función de la razón que subyace a la modificación: violación de principios y normas contables; opacidad; incertidumbres por gestión continuada (GCUs); y otras incertidumbres (non-GCUs). Se observa una incidencia significativamente mayor de OAMs en subsidiarias de grupos extranjeros que en las de grupos locales. Este resultado se deriva fundamentalmente de las modificaciones de opinión relacionadas con la falta de transparencia (opacidad). La evidencia de una mayor incidencia de modificaciones por violación de principios contables e incertidumbres distintas de la gestión continuada en subsidiarias con control extranjero es poco concluyente; y las modificaciones por gestión continuada son significativamente menos frecuentes en las subsidiarias de grupos extranjeros. A diferencia de los resultados en el contexto de la empresa cotizada, nuestros resultados sugieren que el control extranjero en la empresa no cotizada está asociado a empresas más opacas. Este trabajo contribuye a una mayor comprensión de los efectos de la inversión directa extranjera (FDI) en las empresas del país receptor.

Published: July 2022

This study analyse the impact of female on the management of financial risk faced by local governments (LGs), through political and population variables. We conduct a statistical analysis of panel data to examine the financial behaviour of 133 large LGs in Spain during the period 2009-2017. The results reveal that LGs with a female mayor are at lower risk of default. Likewise, we found that the number of female members of the city council and the degree of political fragmentation are inversely associated with the risk of default. This risk is also alleviated by population variables, such as a larger female population, a larger rate of unemployment among women and a smaller population of women aged over 65 years. Our findings have important implications and usefulness for a wide range of stakeholders, including policymakers, managers, practitioners and fiscal authorities concerned by solvency, financial risks and possible default in LGs.

En este estudio se analiza el impacto de la mujer en la gestión del riesgo financiero de los gobiernos locales (LGs), a través de variables políticas y demográficas. Se realiza un análisis estadístico de datos de panel para examinar el comportamiento financiero de 133 grandes LG en España durante el período 2009-2017. Los resultados revelan que los LGs con un alcalde mujer tienen un menor riesgo de impago. Asimismo, descubrimos que el número de mujeres miembros del ayuntamiento y el grado de fragmentación política están inversamente asociados al riesgo de impago. Este riesgo también se ve aliviado por variables poblacionales, como una mayor población femenina, una mayor tasa de desempleo entre las mujeres y una menor población de mujeres mayores de 65 años. Nuestras conclusiones tienen importantes repercusiones y utilidad para una amplia gama de interesados, incluidos los encargados de formular políticas, administradores, profesionales y autoridades fiscales preocupados por la solvencia, los riesgos financieros y el posible incumplimiento en los LGs.

Published: July 2022

In recent years, policy makers have paid more attention to cycling when considering sustainable mobility plans. Understanding the spatio-temporal patterns of cycling mobility can serve as a reference for planning cycling infrastructures. This study explores the application of the Getis-ord Gi* statistic, spreading the values of counter stations by spatial interpolation methods to analyse the geographical effects of the winter season for cycling mobility in Valencia (Spain). From 447,845 measures collected by 59 loop detectors, the variability in the number of bicycles on working days and on weekends in terms of consecutive, dismissing, intensifying, persistent, oscillating, sporadic, or new hot/cold spots was analysed with a time variation of 30 minutes. In contrast to what would be expected, the winter season does not have a significant influence on the use of bicycles around university campuses on weekdays or in recreational areas on weekends, defining these as hot spots. Instead, the Valencia surroundings present persistent and intensifying cold spots, being limited by subway stations during winter when changes occur in the means of transport. Persistent hot spots show accepted mobility patterns among the population of Valencia that could be promoted by the local government, e.g., by improving the availability of bicycles among students and designing attractive weekend rides for all citizens as a healthy activity.
Keywords: Getis-Ord Gi*, Spatio-temporal analysis, spline interpolation with barriers, cycling activity

The habits influence the sustainability of our cities in terms of mobility in our daily lives. The main objective of this study is to achieve a sustainable mobility model from a new approach. This new approach differs from the traditional mobility management model, which focuses on a single department in charge of vehicle traffic that develops models based on surveys. In this research, geoprocessing techniques and spatial analysis tools have been applied to the positioning of taxi vehicles. The interdependence between taxis and other urban public transport has been proven through this analysis.
It should be noted that this study shows that the mobility pattern of the taxi service in a medium-sized city is influenced by quantitative variables of a very diverse nature, such as population, infrastructure and means of transportation. In this way, taxi mobility is explained as a function of pedestrian accessibility to other means of transport. The multiple regression models obtained show a high R2 (around 0.9), demonstrating that access to other modes of transport significantly impacts the mobility of the taxi service.
METHOD FOR CHARACTERIZING TRAFFIC CALMING MEASURES TO EVALUATE THEIR IMPACT ON POLLUTION
Authors: Infante Francés Manuel , MATEO SANGUINO TOMÁS DE J.
Published: July 2022

Traffic calming measures combat speeding and other unsafe behavior by drivers, proving their effectiveness in reducing the frequency and severity of accidents. However, some measures include road results that cause a negative impact on the environment. The objective of this work is to analyze the repercussion of reducing the speed of a vehicle on exhaust emissions and fuel consumption (FC) when driving over a bump. To do this, this article presents a procedure based on two methods applied to RDVs. The first is based on an application that measures the physical impact on a vehicle from acceleration data taken with the IMU of a smartphone in a direction perpendicular to the chassis. The second is aimed at inferring the increase in emissions and FC by taking the speed-time profile of a path because of decelerating, approaching and moving away from the bump. The experimentation carried out with a standard two-passenger vehicle circulating on a section of road with RDV with a trapezoidal section and with a circular section in front of the same section without RDV found a significant physical impact in both scenarios, resulting in an increase in CO emissions, HC, NOX, CO2 and FC associated with speed decreases of only 20 km/h and 10 km/h, respectively. This demonstrates the generalization and usefulness of the proposed method for the study of the increase in emissions and fuel consumption of different «traffic calming» measures on the road.

Sweet potato is a local food that can be used to support food diversification programs. It can be used as a raw material to produce a diverse type of food products, for example  noodles. The addition of sago starch and banggai starch to sweet potato noodle dough is to improve the quality of noodles because these two starches are more prone to retrograde. The purpose of this study was to determine the effect of starch type, extrusion temperature, and water addition on the sweet potato noodles’ quality. The types of starch added were sago starch and banggai starch, with extrusion temperature settings, which were 90 and 95°C, and the water additions were 40 and 35%. Analysis was carried out on the characterization of the flour and physical properties of sweet potato noodles. The best noodle processing conditions were with the addition of 15% sago starch, 95°C extrusion temperature, and 40% water added. This formula produced sweet potato noodles with low brightness, having redness and yellowish colour. It had a hardness value above 3000 g, with higher elasticity and elongation than the other formulas, and also had lower adhesiveness and  cooking loss value.

The inhibition of pancreatic lipase and the associated reduction of lipid absorption has become the most appropriate approach for treating obesity. Meanwhile, katuk (Sauropus androgynus) leaves are rich in polyphenols that act as natural bioactive compounds and are also responsible for the potential effect on metabolic diseases, including inhibition of pancreatic lipase activity. Naturally occurring polyphenols can inhibit pancreatic lipase and consequently affect fat digestion as well as energy intake. Therefore, this study aimed to optimize the inhibitory activity of pancreatic lipase, which plays an essential role in lipid absorption. In fermented katuk (Sauropus androgynus) leaves were brewed following RSM using a Box Behnken design. Data analysis was used to optimize the formulation with a response surface model consisting of three factors namely sucrose concentration ranging from 10-20% b/v, culture 10-20 b/v, as well as fermentation time of 1-5 days. The parameters tested were the percentage inhibition of pancreatic lipase, antioxidant activity, polyphenol, and total acid. Based on the RSM optimization results obtained from the three influencing factors, the optimum conditions were established namely 10.43% w/v sucrose, 10% v/v kombucha culture, and fermentation for 5 days. These conditions yielded the most optimal responses, with the percentage inhibition of pancreatic lipase, antioxidant activity, polyphenol, and total acid being 86.13%, 96.27%, 0.97 mg GAE/mL, and 1.11%, respectively. In general, the results demons-trated that the RSM method of the Box Behnken design and the parameter prediction values obtained using the model equation are in good agreement with the experimental values with at least R2 ≥ 0.8.

Black garlic is produced by processing multi-bulb garlic (Allium sativum) or single-bulb garlic in high temperature and high humidity for several days. Black garlic has many health benefits, such as an antioxidant activity resulting from its compound, including groups of flavonoid and phenolic compounds. This study aimed to analyze the effect of aging time on multi-bulb and single-bulb black garlic on the content of total phenolic, flavonoid, and antioxidant activity. Black garlic was processed at a 60-70°C heating temperature and 70-80% relative humidity for 25 days. Determination of total phenol and flavonoid contents was conducted using spectrophotometric methods with gallic acid as a standard of total phenolic and quercetin as a standard of flavonoid, while the antioxidant activity was determined by DPPH radical reduction. The results showed that total phenolic contents (% w/w GAE), flavonoids contents (% w/w QE), and EC50 values at 0 until day 25 increased on a particular day in multi-bulb and single-bulb black garlic. The optimal total phenolic content of both black garlic was obtained by heating for 20 days, flavonoid content of multi-bulb garlic for 10 days, and single-bulb black garlic for 15 days. Highest antioxidant activity was obtained on days 20 and 25 for single-bulb black garlic and multi-bulb black garlic, respectively. The aging time of black garlic affects total phenolic, flavonoid content, and antioxidant activity. In general, longer processing time caused an increase in the total phenolic content, flavonoid content, and antioxidant activity of both black garlics. Multi-bulb black garlic showed higher phenolic or flavonoid content and antioxidant activity than single-bulb black garlic.

Factor analysis of non-financial motivators will be presented through a statistical model whose goal is to group factors. Composing a statistical model implies grouping the factors that determine the contributions of qualitative preference to business efficiency of the whole company. Empirical material is obtained by surveying the target group, and the response pattern to clarify the management problem is factor analysis. The purpose of factor analysis is to rationalize the number of dependent variables of business efficiency in relation to qualitative and quantitative requirements within the surveyed target group. Considering the modern lifestyle, it is reasonable to assume that general dissatisfaction level is increasing every day. This includes professional orientation, working conditions, leisure time management and all levels of interpersonal relationships such as collegial, friendly, partner and family relationships. It is reasonable to assume that within business systems there is a space for recognizing this dimension and its careful analysis that respects the non-economic dimension of employees’ (dis) satisfaction and manages business efficiency in terms of non-economic factors. This paper aims to present thorough analysis of grouped factors that are basically non-financial; they represent a group of spiritual factors that contribute to a better internal climate of the company. All this leads to a prosperous company management that can represent and promote the company in public well.

The analysis of monetary variables and their impact on the economic growth rate has always been in the focus of economic research. In the broadest sense, economic theory distinguishes two basic views defined by the views of monetarists and Keynesians. Although the basic difference is reflected in the determination of price rigidity and money neutrality, specifics of modern economic systems shift the focus towards the positive influence of monetary on real variables. The aim of our research is to identify and quantify the impact of monetary variables on economic growth in Bosnia and Herzegovina. The research was conducted using data from the period 2000-2020. The paper starts with the hypothesis that money supply and inflation ultimately have a positive impact on the real economic growth in BiH. The money supply M2 and the annual inflation rate are taken as explanatory (monetary) variables in the research, while real growth is a dependent variable. The long-term relationship between monetary variables and real growth rates was tested, taking into account the specificity of the BiH monetary arrangement established in the form of a currency board. In order to prove the hypothesis, we applied econometric techniques such as VEC model, cointegration analysis, innovation analysis based on the impulse-responsive function, decomposition variance as well as a causality test. The research results showed the connection between the money supply and the inflation rate with the economic growth in BiH, the relation being positive and statistically significant in the long run. With this, we confirmed the initial hypothesis of the work.

In contrast to climatic data, piezometric records are often fragmented both in time and space continuity, despite their crucial importance in groundwater studies. This work presents a new method for analysis of groundwater level vs. recharge processes relation from fragmented piezometric data, called Antecedent Recharge Temporal Effectiveness (ARTE). The ARTE method was tested on 5 year-long (2016-2020) water table level datasets measured by three automatic piezometers located in the Lucca plain (Tuscany, Italy). For each piezometric level time series, measurements were extracted every 30, 60, and 120 days, and randomly, obtaining fragmented records inlcuding less than 3% of the complete time series. As for recharge processes of the monitored aquifer, rainfall and riverbed infiltration were selected. Hence, daily rainfall and daily mean river stage time series were acquired from different automatic raingauges and hydrometers respectively. The relationship between these recharge processes and the variation of the piezometric level from the artificially fragmented datasets were evaluated with the ARTE method. The ARTE method was potentially able to identify maximum correlation time intervals, for which the recharge processes are most likely to influence the groundwater level. Based on the analysis conducted on the fragmented piezometric datasets, the reconstruction of each piezometric time series was attempted for the study period. The simulated daily groundwater level records have RMSE values between 0.21 m and 0.73 m and NRMSE values between 0.08 and 0.16, which are satisfactory results when compared with other more complex simulation procedures, in which the training datasets are increasingly larger.
