Abstract
Spring floods in Siberia annually affect local communities. Major urban settlements in the region implemented flood control structures, so rural areas take a heavy beating. In 2018, spring floods severely hit multiple communities in central Yakutia, exposing deficient flood prevention and risk management practices. Notably, Amga village, an important local center, was severely inundated. Hydrological analysis shows that the 2018 flood had a 50-yr return period, and was caused by an ice jam in a nearby channel bend where mid-channel sand bars impede ice movement during breakup. The cold spells of late April and early May in the middle section of the river promote ice-jam development, causing extreme water stage rise. Highest water stage is unrelated to either winter snow water equivalent or early May rainfall. Estimated tangible direct damage to the Amga community equals 5.1B ($81.5M) in 2018 prices, but only 0.13B ($2.1M), or 2.5% of this total, was reclaimed. A questionnaire survey revealed that most residents report important deterioration of drinking water quality and health after flooding. Residents respond positively to risk mitigation actions, implemented by the local and regional authorities, except ice dusting and cutting, and report minor activity of official sources in spreading information on flood progress.
Indicators of Adrenal Insufficiency in TB-suspect Patients Presenting with Signs and Symptoms of Adrenal Insufficiency at Three South African Hospitals in Pretoria
Authors: Mabuza Langalibalele H. , Sarpong Daniel F. 
Published: May 2020

Background:
Primary adrenal insufficiency occurs when the function of the adrenal cortex to produce cortisol is impaired. Infections, such as disseminated Tuberculosis (TB) and malignancies, are the major causes of Adrenal Insufficiency (AI) in developing countries. AI is characterized by specific symptoms, signs, and laboratory findings.

Objective:
To determine indicators of AI in TB-suspect patients presenting with signs and symptoms of AI.

Methods:
A cross-sectional study was conducted at the primary health care ward of Dr. George Mukhari Academic Hospital, Jubilee District Hospital, and Odi District Hospital. The population comprised all TB-suspects, from whom a sample of 75respondents was obtained. A researcher administered questionnaire was used to collect data related to their signs, symptoms, and laboratory findings.

Results:
Of the 75 respondents, 47 (62.37) and 28 (37.3%) were classified as Adrenal Sufficiency (AS) and AI, respectively. The most occurring symptoms were craving for salt, dry, itchy skin, and vomiting (prevalence: 79.7%, 68.1%, and 69.0%, respectively). Signs or symptoms by themselves did not discriminate persons with a high likelihood of AI. However, a fasting serum glucose (≤ 5.25 mmol/L), a positive GeneXpect, a low CD4 count (≤ 274.5 cells/ml), with a combination of signs and symptoms (9.5) constituted a discriminator for AI in TB-suspect patients (87.5% likelihood).

Conclusion:
A low fasting serum glucose, a positive GeneXpect, a low CD4 count with a minimum of ten signs and symptoms constitute a discriminator for AI in TB-suspect patients, necessitating treatment initiation to save patient lives in laboratory resource-limited settings.

Authors: Şen Zekâi 
Published: May 2020

Background: There are different methodologies for DNA comparison based on two string algorithms, which are dependent on crisp logical principles, where there is no room for verbal (linguistic) uncertainty. These are successfully applicable procedures in DNA bioinformatics researches even by taking into consideration probabilistic random variability components based on the probability distribution functions of various types.

Objective: The main purpose of this paper is to review first briefly all available DNA string matching methodologies that are based on crisp logic and then to suggest a new method based on the fuzzy logic rules and application.

Methods:
There are different methodologies for DNA comparison based on two string algorithms, which are dependent on crisp logical principles, where there is no room for verbal (linguistic) uncertainty. These are successfully applicable procedures in DNA bioinformatics researchers even by taking into consideration probabilistic random variability components based on the probability distribution functions of various types.

Results:
Fuzzy number representation of each gene implies some sort of uncertainty or unhealthiness in some or all the genes. Their better identifications can be achieved on the basis of fuzzy numbers with different membership degrees, which imply the unhealthiness or healthiness of the genes and their collective behaviors.

Conclusion: After the development of fuzzy number representation of the text string coupled with crisp pattern string their relationships are searched at different shift operations, and hence, the possibility of defaulters are identified in the text string with a certain degree of membership.

Published: May 2020

AbstractStudent‐led conferences are a type of inquiry learning and student‐led pedagogy. They have the potential to foster learning across many of the domains required for professional dental practice including communication and interpersonal skills, adaptive capability, professional attitude and ethical judgment, entrepreneurship, and a social and community orientation. A student‐led conference, which provided a framework for students studying oral biosciences to create and host a conference focused on contemporary issues in oral biosciences, was introduced into the Bachelor of Oral Health program at the University of Sydney in Australia in 2017 and 2018. The aim of this qualitative study was to examine the educational purposes that the student‐led conference satisfied. Data were collected from the 2017 cohort of students in the form of reflective essays. In 2018, students’ experience of the conference was recorded from a focus group discussion. In both years, reflective accounts written by attendees were collected. The thematic analysis generated four themes: integration of learning, personal learning, student resourcefulness through peer relationships, and deep commitment to delivering an excellent conference. The learning project served as a platform for students to display their professionalism and skills gained in entrepreneurship, communication, and adaptive capability. This study provided an example of a participatory curriculum approach with the potential to help students generate a working understanding of knowledge structures and how knowledge is created and circulates in the discipline.

Published: May 2020

<em>Culture of architectural photography is a branch of photography that exposes the aesthetic value of an architectural object of a building<strong>.</strong> The presence of drone technology in the culture of photography recently brings changes to the results of the photography itself and one of them is in the area of architectural photography. This study aims at verifying the influence of Unmanned Aerial Vehicle technology (Drone) on the artwork of architectural photography. The method used in this research was qualitative method with descriptive technique. Data were collected through library research and field research with observation and interview techniques. The culture using drones offer significant results in architectural photography artworks. The high flexibility of the drone gives results on a very detail architectural artwork. Using a drone also provides a very dazzling point of view that cannot be obtained by using only a DSLR camera. Furthermore by using drone, the artworks of photography are no longer limited by areas that cannot be reached. Therefore by using a drone, the photographer can make architectural photography works with unlimited perspective dimensions. There are some weaknesses of using this drone that the camera and lens are not adjustable and they also cannot be changed.</em>
The Effect of the Storage on the Content of the Malvidin-3-Glucoside in Red Wine
Authors: Soural Ivo , Šnurkovič Petr , Tománková Eva , Forneck Astrid 
Published: May 2020

Abstract
Anthocyanins are plant dyes responsible for the colour of red wine. Of these, malvidin-3-glucoside is the most significant member and its content was monitored in wines that were first left to age in oak barrels for 12 months, subsequently bottled and sealed with plastic/cork stoppers. The malvidin-3-glucoside content was also studied in the same wines that were bottled right away without aging in barrels. Analyses were conducted within the time spans of 3 to 30 months. The highest malvidin-3-glucoside concentrations were found in month 3 of the aging process, and they significantly decreased in month 6 and month 15 of storing. Between month 15 and month 30 of storing, the content of malvidin-3-glucoside basically remained unchanged. The results of the measurements show that to preserve higher malvidin-3-glucoside levels for longer periods of time, it is better to store wine in barrels rather than in bottles and when a bottle is used instead of a barrel, a plastic stopper is better than a cork stopper.

Published: May 2020

Abstract
A study was carried out at the Federal University of Agriculture Abeokuta, Nigeria to determine the gene action underlying the inheritance of important agronomic traits as well as the general combining ability (GCA) and specific combining ability (SCA) of the parents and hybrids, respectively. Ten hybrids were developed by crossing five lines to two testers. The hybrids and parents were evaluated on the field in a randomised complete block design replicated three times, and data were collected on days to 50% flowering, number of branches, stem diameter, plant height, pod length, pod width, pod weight, number of pods and pod yield. The data were subjected to line by tester analysis and results showed substantial variability among the genotypes for some of the characters measured. Days to 50% flowering, number of pods and pod yield were largely under additive gene action while non-additive gene action was more important in the inheritance of plant height. Favourable GCA and SCA effects for days to 50% flowering were observed in NGB00356, NGB00326 and NGB00347 × NGB00326, respectively. The tester NGB00326 had a positive and significant GCA effect for number of pods while the highest positive SCA effect for pod yield was found in NGB00297 × NGB00326. Thus, NGB00356 and NGB00326 could be considered as sources of alleles for development of early maturing while the cross NGB00297 × NGB00326 could be exploited for high yielding okra genotypes.

Authors: Peter Ildiko , Matekovits Ladislau 
Published: May 2020

Abstract
This paper deals with the design of metamaterial (MTM) substrates to be used in electromagnetic devices. In particular, the approach has been considered for different investigations having the scope the realization of antennas on flexible substrates. The importance of the topic resides in the potential of conforming the antenna to/on desirable shapes. Flexibility is well exploitable either in advanced communication systems or in biomedical applications, just to mention some. The proposed MTM is made of metallic spherical inclusions of AISI52100, which are embedded in a polymer host. The paper aims to assess the feasibility of increasing the performance of a microstrip patch antenna, and to decrease its size by using the MTM substrate, which is able to locally control the permittivity of the substrate and to create electromagnetic band-gap regions outside of the patch.

Abstract
This paper aims to mirror the way the European Professors of Industrial Engineering and Management (EPIEM)network perceives itself with a students’ view. Along with a presentation of the status quo of the EPIEM network, a brief survey among students is deployed to get an impression of the perception of EPIEM by its most active partner association - the European Students of Industrial Engineering and Management (ESTIEM). The explorative findings (i) provide insights into the current situation of EPIEM from an inside and outside perspective and (ii) deliver ideas for the future development of the EPIEM network. With regard to the relationship management practice between EPIEM and ESTIEM this research represents an innovative approach within the European IEM organizations.

Abstract
The theoretical research and substantiation of specialists compliance estimation with corporate requirements on the basis of international certification and determination of its role in the system of enterprise’ staff management are carried out in the article. The algorithm of the enterprise’ effect achievement of the preliminary international certification of the personnel involved in oil and gas wells drilling is offered. The relationship between the number of persons trained and certified by International Well Control Forum in Drilling Simulation Center of the Ivano-Frankivsk National Technical University of Oil and Gas and the volume of drilling of oil and gas wells in Ukraine is analyzed. The task was accomplished by means of correlation and regression analysis. The results of the calculations allow us to make sufficiently plausible assumptions about the impact of training and certification on drilling volumes. It is established that the increase in the number of persons certified according to International Well Control Forum for one person will allow to expect the volume of drilling of oil and gas wells by 0.734 thousand metres per year.
Does regular quality control improve the quality of surgery in Slovenian breast cancer screening program?
Authors: Perhavec Andraz , Milicevic Sara , Peric Barbara , Zgajnar Janez 
Published: May 2020

Abstract

Background
The aim of our study was to evaluate the quality of surgery of Slovenian breast cancer screening program (DORA) using the requested EU standards. Furthermore, we investigated whether regular quality control over the 3-year period improved the quality of surgical management.

Patients and methods
Patients who required surgical management within DORA between January 1st, 2016 and December 31st, 2018 were included in the retrospective study. Quality indicators (QIs) were adjusted mainly according to European Society of Breast Cancer Specialists (EUSOMA) and European Breast Cancer Network (EBCN) recommendations. Five QIs for therapeutic and two for diagnostic surgeries were selected. Additionally, variability in achieving the requested QIs among surgeons was analysed.

Results
Between 2016 and 2018, 14 surgeons performed 1421 breast procedures in 1398 women. There were 1197 therapeutical (for proven breast cancer) and 224 diagnostic surgical interventions respectively. Overall, the minimal standard was met in two QIs for therapeutic and none for diagnostic procedures. A statistically significant improvement in three QIs for therapeutic and in one QI for diagnostic procedures was observed however, indicating that regular quality control improves the quality of surgery. A high variability in achieving the requested QIs was observed among surgeons, which remained high throughout the study period.

Conclusions
Adherence to all selected surgical QIs in patients from screening program is difficult to achieve, especially to those specifically defined for screen-detected lesions. Regular quality control may improve results over time. Reducing the number of surgeons dedicated to breast pathology may reduce variability of management inside the institution.
Comparison of Estimators of Equity Return Standard Deviation Using Pitman Closeness Criterion and Control Charting Applications
Authors: Alan Chow , Dane Lahtinen Kyre , Kelsey Edwards 
Published: May 2020

Abstract
Measurement of dispersion and variation have been studied and evaluated in many applications. Volatility in the field of finance is an important measure as it directly impacts allocation, risk management, and valuation. Pitman Closeness criterion is used to compare estimators of standard deviation from equity returns in a control charting application. Three estimators are evaluated over the 30 DJIA component stocks in an effort to determine if one method of estimation has better performance within an application of control charting for identifying outliers. The study uses three sample sizes to also determine if the better estimator is sample size dependent.
Are Determinants of International Financial Integration in the European Transition Countries Different from Post-Transition Countries?
Authors: Mehmed Ganić 
Published: May 2020

Abstract
The paper seeks to empirically explore the variations and changes in the degree of International Financial Integration (IFI) between the European Transition countries and Post-Transition countries between 2000 and 2016. The estimation of parameters was made using the Generalized Method of Moment (GMM) approach. The findings of the study reveal that European Post-Transition countries have relatively more developed financial systems compared to European Transition countries, where private credit market is still playing an overwhelmingly important role in a financial system while stock markets are in an early stage of development constituting a relatively small share of the financial system. Even though in Panel 3 there are significant control variables, our findings reveal that IFI in European transition countries are affected neither by stock market capitalization and private credit markets. Consequently, they can’t be used in this stage of financial development for explanation of variations and changes in the degree of IFI.
Study Regarding the Effects of Demographic Transition on Labor Market and Public Pension System in Central and Eastern Europe

Published: May 2020

Abstract
Population and the quality of labor force are the “strengths” features’ that ensure socio-economic development of a country. The last decades can be characterized as a transitional period, in which countries of European Union and especially the countries of Central and Eastern Europe are facing a demographic decline. Reduced birth rate, ageing and migration are factors’ which create a lot of pressure, both on labor market and public pension systems, items correlated with the population structure. In this paper we have presented the demographic situation and the size of migration in five countries of Central and Eastern Europe. The direct linkage between population structure, labor market and public pension systems represents, in transitional context, a threat to budget sustainability, especially in Romania. We consider that the reformation has to be adjusted with the new socio-economic conditions, finding new solutions for increasing birth rate, decreasing the “exodus” of young population and stimulating economic activities.
An Alternative View to the Global Coal Trade: Complex Network Approach
Authors: Semanur Soyyigit , Hüseyin Topuz , Halil Özekicioğlu 
Published: May 2020

Abstract
The role of energy for the developmental process of nations is a known fact due to being crucial input for any phase of production of goods and services. That’s the reason why countries that are rich in energy resources also have strategic power in terms of the international trade of these resources. On the other hand, it becomes important to provide energy security for countries that are resource-poor. Although green energy has become preferred one, fossil fuel energy keeps its place as one of the most used energy resources. That's why in this study it is aimed to determine major providers and users of coal as a type of fossil fuel energy resources. It is vital to investigate the structure of global coal trade structure to determine the weaknesses and strength of supply and use of coal. Network approach provides a holistic view to the system analyzed and presents more realistic (high-degree) indicators to analyze it. In this study, global trade network of coal is analyzed from 2000 to 2017 via network analysis. Changing structure and evolution of global coal trade has been revealed via some topological parameters which are specific to complex networks such as density, clustering, assortativity/disassortativity, centrality and degree distribution.
