Development of Receptive Factors on the Principles of Sustainable Tourism Development - Budva Case
Authors: Županović Ivo , Krivokapić Ana 
Published: July 2020

Abstract
Sustainable tourism implies establishing a positive relationship and link between tourism development and environmental protection, i.e achieving a full harmony between economic and environmental interests. Tourism that is based on respect for ecological interests can ensure the constant maintenance of balance in the natural environment and tourism development. Building a private accommodation association, as one of the aspects of sustainable tourism, ensures the long-term sustainability that is needed for the destination of Budva, due to the large number of problems it encounters, starting from the gray business zone to the very poor quality private accommodation, which is higher than in basic accommodation, which should be the basis of tourism development. In view of the given problem, the subject of research of this paper is the direction in which the receptive factors in the destination of Budva should be developed, with reference to the basic and complementary accommodation units.
The aim of the research is to provide a solution for the currently unfavorable receptive situation in the destination, with special focus on diffused and integral models of private accommodation.

Published: July 2020

Abstract
In sharp crested weirs, significant changes occur in the hydraulic characteristics of the flow past the weirs with different geometry. A detailed investigation and better understanding of hydraulic behavior will help practically to choose an appropriate geometry for weir. The purpose of this research is simulate the flow over sharp crested weir and investigate the effect of geometric shapes of sharp crested weirs on hydraulic characteristics of the flow such as pressure, velocity, water level profiles and discharge coefficients. Thus the limitation and usage range of sharp crested weirs are clarified. In this research OpenFOAM open source 3D software with RNG K-ε turbulence model and Volume of Fluid method (VOF) was used to analyze the hydraulic flow passing through sharp crested weir. The correlation coefficient for flow Surface profiles and discharge coefficients among numerical and experimental data is obtained 0.96 for different discharge rates. In the present research, discharge coefficients for rectangular weirs with compression coefficient 0%, trapezoidal and triangular weirs are determined 1.20, 0.68 and 0.51 respectively using discharge rate of 0.05183m3/s. The maximum discharge coefficient is obtained for rectangular sharp crested weir while the triangular sharp crested weir has minimum discharge coefficient.
Restructured class of estimators for population mean using an auxiliary variable under simple random sampling scheme
Authors: Baghel S. , Yadav S. K. 
Published: July 2020

Abstract
The present paper provides a remedy for improved estimation of population mean of a study variable, using the information related to an auxiliary variable in the situations under Simple Random Sampling Scheme. We suggest a new class of estimators of population mean and the Bias and MSE of the class are derived upto the first order of approximation. The least value of the MSE for the suggested class of estimators is also obtained for the optimum value of the characterizing scaler. The MSE has also been compared with the considered existing competing estimators both theoretically and empirically. The theoretical conditions for the increased efficiency of the proposed class, compared to the competing estimators, is verified using a natural population.
When cultural strength means political weakness: Romania’s marriage referendum and the paradox of conservative mobilisation
Authors: Racu Alexandru , Giugăl Aurelian , Johnston Ron , Gavriş Alexandru 
Published: July 2020

Abstract
Held on 6–7 October 2018, the Romanian referendum on the topic of gay marriage was the fourth referendum of this kind organised in East Central Europe over a five-year period. Because turnout was low in all of them and demands explanation, this paper: i) discusses the common characteristics of these Eastern European marriage referendums, contextualising the Romanian referendum; ii) overviews the history of the Romanian referendum, emphasising the legal, political, ideological and societal aspects; iii) quantitatively examines the electoral geography of the voting patterns; and iv) interprets qualitative data seeking to understand the voters’ choices and why conservative mobilisation was so weak.
Geographies of tacit knowledge transfer: Evidence from the European co-authorship network
Authors: Jeck Tomáš , Baláž Vladimír 
Published: July 2020

Abstract
The patterns of scientific cooperation between the 28 European Union (EU) member countries, Switzerland and Norway, from 1993 and 2017, are evaluated in this article. We consider co-authorship patterns to be proxies for international transfers of tacit knowledge. The theoretical part of the paper contains propositions by researchers in evolutionary economic geography on path-dependence, selection and variation, and the role of networks in knowledge transfer. The principal argument is that the geographical configurations of knowledge transfers over distance are shaped via a set of connectivities – specific communication channels for the exchange of people, goods and knowledge between two or more countries. Some connectivities are more conducive for the transfer of explicit knowledge (e.g. merchandise trade, trade in patents), while human exchange flows (students, migrants, travellers) favour the transfer of tacit knowledge. The research project found that a considerable increase in human exchanges has helped to increase the total number of co-authored papers, but did not amend the geography of the European co-authorship network over last two decades. Rather, the layout of the network stems from a relatively stable set of historical, cultural and political legacies in Europe.
Commuting pays off: Evidence on wage returns to inter-urban and intra-urban commuting
Authors: Vontroba Jakub , Balcar Jiří , Šimek Milan 
Published: July 2020

Abstract
The distance a person is willing to commute has a direct influence on her/his employment opportunities and wage level. It raises a lot of interesting questions, especially whether intra-urban commuting (due to a well-developed transport infrastructure, geographical concentration of job opportunities, etc.) is connected with any wage returns, and how they differ in comparison with those of inter-urban commuting. This article uses three data-sets at national (N1 = 1,884; N2 = 933) and local (N3 = 3,193) levels from the Czech Republic, and different approximations of commuting in order to contribute to the discussion. It provides robust evidence on positive wage returns to both inter-urban and intra-urban commuting, comparable with Western countries. The differences between large national and limited urban labour markets are reflected in functional form: wage returns are linear for intra-urban and non-linear for inter-urban commuting. The article also explores the validity of different measures of commuting time and distance provided by the on-line application Mapy.cz, and suggests that it represents a suitable approximation in the case of missing or limited data.
Evolution of Corvids and their Presence in the Neogene and the Quaternary in the Carpathian Basin
Authors: Kessler Jenő Eugen 
Published: July 2020

Abstract
Corvids are the largest songbirds in Europe. They are known in the avian fauna of Europe from the Miocene, the beginning of the Neogene, and are currently represented by 11 species. Due to their size, they occur more frequently among fossilized material than other types of songbirds, and thus have been examined to the largest extent. In the current article, we present their known evolution and their fossilized taxa in Europe and examine the osteology of extant species.
The Effects of Creatine and Related Compounds on Cardiovascular System: From Basic to Applied Studies
Authors: Draginic Nevena , Prokic Veljko , Andjic Marijana , Vranic Aleksandra , Pantovic Suzana 
Published: July 2020

Abstract
Beneficial effects of creatine were firstly shown in sport, where itself has been recognized as an ergogenic substance, increasing exercise endurancе, muscle strength and lean body mass. Creatine supplementation is very interesting, due to the fact that creatine supplementation have been reported to be beneficial for wide spectrum of diseases and conditions referring neuro-degenerative, rheumatic diseases, myopathies, cancer, type 2 diabetes. Creatine is a principle component of the creatine kinase/phosphagen system. In cardiomyocytes, it plays an important role in the buffering and transport of chemical energy to ensure that supply meets the dynamic demands of the heart. Studies in mice proved that elevated creatine protects the heart from ischemia-reperfusion injury. A natural precursor of creatine, guanidinoacetic acid (GAA), plays an important role as an energy carrier/mediator in the cell. GAA is formed in the first step of creatine synthesis. Supplementation with GAA might be of great significance in some circumstances where biosynthesis of GAA is limited like deficient diet, kidney failure, renal insufficiency, exercise-related GAA depletion. Betaine is a neutral compound in the form of zwitterion. Betaine supplementation is associated with improved cognition, neuroprotection, cardioprotection and exercise physiology. Betaine insufficiency represents increased risk for secondary heart failure and acute myocardial infarction. This mini-review outlines the evidence in support of creatine and creatine related compounds (GAA and betaine) elevation and examines the pharmacological approaches that are currently available. Since data from the available studies, regarding cardioprotection are inconsistent, this review might help clarifying the benefits of creatine, GAA and betaine supplementation on cardiovascular system.

Weather-Induced Moods and Stock-Return Autocorrelation
Authors: Khanthavit Anya 
Published: July 2020

Abstract
Moods affect investors’ attention, memory, and capacity to process information. Inattentive investors delay the price adjustment process, thus leading to a positive autocorrelation of asset returns. In this study, I investigate the relationship between weather-induced moods and stock-return autocorrelation in the Stock Exchange of Thailand from January 2, 1991, to December 29, 2017. Only good moods contribute significantly to return autocorrelation.

Published: July 2020

Abstract
The goal of the article is to describe factors influencing purchases of organic food by consumers in a selected area of the Czech Republic. We have researched and analysed reference books and studies focused on the topic to fulfil the goals of the article. Data acquired during a questionnaire survey with selected consumers was used as primary data. The impact of different factors on the purchase of organic food was researched based on an effect of demographic indicators. Hypotheses were stated to study relations among variables, and we examined the statistical importance and correlation of particular hypotheses. We used another statistical method – a decision tree – to seek connections between the variables. The results show that purchases of organic food are influenced by the price, the taste, the sense of health and the content. The connection between the researched factors and demographic indicators is usually low and statistically insignificant.

Published: July 2020

Gotu kola (Centella asiatica) is a traditional herbal plant that has been reported have a variety of pharmacological activities. The compounds of gotu kola that play a role on pharmacological activities are triterpene group compounds, namely madecasosside (MD), asiaticoside (AS), madecassic acid (AM), and asiatic acid (AA). Stress can affect the production of biomass and secondary metabolite compounds in plants. The aims of the study is to analyze the effect of salinity and drought stress on biomass and 4 compounds of triterpene in gotu kola. Harvesting is done when the plant is 8 weeks old. The yield of the biomass was analyzed and then extracted using methanol solvent to be analyzed secondary metabolite levels using the high performance liquid chromatography (HPLC) method. The lowest crop biomass was obtained at 50% of field capacity and 3,000 ppm salt content. The highest levels of MD and AS were established in conditions of 100% field capacity and 1,000 ppm salt content. The 50 and 100% field capacity and 1,000-3,000 ppm salt content did not affect the levels of AM and AA.

National data shows the prevalence of coronary heart disease is 3,6%. The prevalence of dyslipidemia is around 35,9%. Dyslipidemia has a causal relationship with cardiovascular disease. Based on previous research, 70% ethanolic extract of Ridge Gourd has been shown to have antihyperlipidemic activity. This study aimed to study the activity of 70% ethanolic extract fraction of Ridge Gourd in decreasing the levels of total cholesterol, low-density lipoprotein (LDL-C), and triglycerides in hyperlipidemic hamsters. A total of 32 hamster were divided into 8 groups. Negative control, normal control, positive control (using atorvastatin dose 1,24 mg/kg body weight), positive control (fenofibrate dose 12,35 mg/kg body weight), ethyl acetate fraction, n-hexane fraction, water fraction (fraction doses 36,75 mg/kg body weight), and ethanol extract group (extract dose of 240 mg/kg body weight). The results showed that fraction group (n-hexane, ethyl acetate, water) and ethanol extract group experienced a decrease in total cholesterol, LDL-C, and triglycerides levels. Statistical analysis with one-way ANOVA showed an effect on the treatment given (p = 0,005). Tukey's test showed that ethyl acetate fraction group had an effect comparable to positive control with a decrease in total cholesterol, LDL-C, and triglycerides level by 56,03%, 52,14%, and 59,51% consecutively. Ethyl acetate fraction (doses 36,75 mg/kg body weight) was the most effective fraction in reducing total cholesterol, LDL-C, and triglycerides.
