Corporate management in Greece in the context of debt crisis
Authors:   Economic Research Institute аt BAS, Bezdekidu Vasiliki
Published: June 2023

The article highlights one of the important aspects of the capital market in Greece - the model of corporate management. It studies the specific features s of the Greek model of corporate management, which is dominated by family firms and public companies, with arguments for the view that most public companies have no adequate mechanisms of corporate management. A conclusion was made, that although there are certain results in this area, they are limited to a few relatively large companies seeking to attract international funding. The concept of corporate governance has not been implemented in the Greek business community, which is an obstacle to the expansion of family businesses, for better management of state companies and privatization processes.

Authors:   University of National and World Economy, Tosheva Ekaterina , Draganov Dragomir ,   University of National and World Economy, Boshnakov Venelin ,   University of National and World Economy, Tasseva Iva ,   University of Essex
Published: June 2023

The paper presents some empirical results about the assessment of the effects from tax-transfer policies on incomes of Bulgarian households for the period 2011-2015 obtained by EUROMOD – the tax-transfer simulation model of the EU – utilizing data from EU SILC survey. The simulation analysis was performed by tracking the changes in household income distribution for any year from the period where the policy parameters from the base year (2011) were replaced by those enacted for each year, holding the population structure and gross household market incomes fixed at the base year. The results show that the changes in the policies brought in income increments mainly for the households in the lowest income groups. Poverty rate decreases by 1.3-2.9 percentage points (depending on several levels experimented for the poverty threshold). Nevertheless, the poverty level in Bulgaria is among the highest in EU and special measures should be launched in order to enhance the living standard of Bulgarian households.

Fundamentals of modern economy: Irving Fisher and intertemporal choice theory
Authors:   Economic Research Institute аt BAS, Todorov Vasil
Published: June 2023

This article summarizes the life and work of Irving Fisher – one of the most influential economists of the 20th century, famous in his lifetime for being a genius. Besides his groundbreaking contributions to economics, he is also a pathbreaker for topics related to mathematics, statistics, nutrition, health, political stability and peace. His contributions to economics, theoretical and applied, are still used in economics textbooks. This article provides a brief survey of Fisher’s work. It is closely related to the introduction of neoclassical theory in the US at the end of the 19th century. An overview of some of them and elaborate on his model of intertemporal choice are presented. This model is an important link between the general equilibrium theory, the theory of money, the theory of investment and the theory of consumption. The main reasons are being put forward for the Fisher’s work to sound contemporary in the new millennium.

Authors:   nternational Scientific and Educational Center of the National Academy of Sciences of Armenia, Sargsyan Karen
Published: June 2023

The article deals with the issues on fiscal and monetary policies and the economic situation in the Republic of Armenia during the crisis and post-crisis period. The analysis shows that although there have been some signs of economic growth in Armenian economy in 2010-2013, however, the main macroeconomic indicators did not return to pre-crisis level and failed to provide long-term sustainable economic growth in the country. It is argued in the article that expansionary fiscal and monetary measures should be taken for sustainable economic growth. The main target of the fiscal policy should be the reduction of the tax burden, while financing the real sector of the economy and supporting a sustainable growth of the economy should be the primary objective of the monetary policy.
ON THE IMPACT OF TTIP IN SOUTHEASTERN AND EASTERN EUROPE: A QUANTITATIVE ANALYSIS
Authors:   Drexel University, Philadelphia - USA, Larch Mario , Yotov Yoto ,   Economic Research Institute аt BAS, Ifo Institute, Germany
Published: June 2023

Despite great general interest and significant controversy surrounding the completion and the potential impact of the Transatlantic Trade and Investment Partnership (TTIP), little attention has been devoted to the impact of this trade megadeal on the EU-member and non-member countries in Southeastern and Eastern Europe. To fill this gap, the objective of this paper is threefold. First, we want to describe the standard quantitative methods that are used to analyze the impact of trade liberalization. Second, we offer a detailed discussion of the decomposition of the transmission channels through which an initial trade liberalization shock (e.g. the formation of TTIP) will affect consumers, producers and total welfare in member countries as well as outsiders. Finally, throughout the analysis, our focus will be on the countries in Southeastern and Eastern Europe, including member countries (e.g. Bulgaria) and non-member countries (e.g. Macedonia). Our findings suggest that, while TTIP will lead to gains for all South-eastern and Eastern European TTIP member countries, their trade costs with the US are still high. Further Southeastern and Eastern European TTIP outsiders will lose, but losses can be mitigated by additional trade with Southeastern and Eastern European TTIP member and other closer Southeastern and Eastern European countries.

Published: June 2023

In this review, we discussed in brief about the recent emergency update released by the World Health Organization (WHO) (July 22, 2022) on Marburg virus disease (MVD). This virus was first identified in some African countries in 1976 as hemorrhagic fever. This was noticed that year during a series of Marburg virus (MARV) infections in German cities as well as in the Yugoslav capital of Belgrade. The epidemic was linked to research involving African apes transported from Uganda. To complete this review, we used previously published studies related to this disease and a regular visit to the WHO’s official website to know the current status of MVD. Information was collected from Google scholar, PubMed, Research gate, and national library of medicine from September 2022 to December 2022. The main objective of this study is to provide current information on MVD to researchers, practicians, health-care professionals, and academicians due to awareness. If people know about that disease, only then can they handle and prevent it themselves. For this, we include the pathogenesis of the disease, epidemiology status, symptoms of the disease, how to diagnose according to the WHO guidelines, possible treatments according to the WHO, and a brief comparison of COVID-19 and MARV. This is a needful study for future perspective because if no one takes it seriously, then maybe in the future, it will become a severe pandemic like COVID-19.

A Subdivision Transformation Method for Weakly Singular Boundary Integrals in Thin-structural Problem
Authors: HOU Junjian , ZENG Li , ZHONG Yudong , ZHAO Dengfeng , ZHAO Mingyuan
Published: June 2023

Accurate and effective calculation of weakly singular integral in the boundary integral equation of the thin-structural problem is the key to the numerical implementation of the boundary element method. In this paper, a subdivision transformation method evaluated for weakly singular integrals is proposed, and the method is implemented as follows: based on the position of the source points, the shape information of the elements and the nearest distance from the source point to the integral element, a subdivision technology is constructed at first. With this subdivision technology, the integral element can be divided into several integral blocks with good shapes. And then, a simpler coordinate transformation method is constructed to remove the weak singularities of the integral blocks obtained by the subdivision technology. Compared with the conventional polar coordinate transformation method, the present transformation method does not need to calculate their integral interval, which is more simple and effective to implement. Finally, the paper gives three numerical examples to verify the accuracy and validity of the present method.

Authors: WANG Mengqin , XIE Qiyue
Published: June 2023

Abstract:Based on current energy storage technologies such as batteries and fuel cells, the inherent battery capacity of electric vehicles puts constraints on their driving range and requires charging in the process of completing driving tasks. In this paper, with the current practical application in logistics industry as the background, from electric vehicle charging scheduling and path planning, a hybrid algorithm combining genetic-particle swarm algorithm is proposed to plan the best driving route for a group of electric logistics vehicles with vehicle load, vehicle battery life, charging facility location and customer time window as constraints and the total cost as the objective function. Based on the single distribution center, a more complex multi-distribution center electric vehicle path planning problem is considered. In this paper, multiple sets of Solomon VRPTW data sets are selected to test the prepared algorithm, and the results show that the algorithm can effectively plan the best distribution scheme.

Authors: AĞAKİŞİ Gurur , ÖZTÜRK Ferruh
Published: June 2023

Physical and virtual K&C analyses are performed to achieve the vehicle dynamics targets by finding the optimum variables such as the position of hardpoints or stiffnesses of bushings. However, finding appropriate design variables that meet all the aims is challenging. This paper evaluates a hardpoint optimization approach to attain suspension K&C characteristic objectives with the design of experiments, neural networks, and genetic algorithm, based on a reference compact-sized prototype vehicle. The MBD model correlation is provided to optimize the hardpoints to improve the vehicle's steering kinematics concerning Ackerman error and camber angle variation that are out of target in baseline suspension. The results showed that NN based optimization strategy to define the hardpoints has significantly improved targeted characteristics compared to conventional response surface methods in the limited design space.

Published: June 2023

In this paper, based on MATLAB/simulink, the PID vector frequency conversion control of permanent magnet synchronous motor has better drive control performance in the multi-stage centrifugal pump speed control system. The electric-hydraulic coupling system of centrifugal pump has a good evaluation and research function. In view of the low efficiency of the traditional PID control method and the poor adaptability to the change of working environment, a vector control method of permanent magnet synchronous motor based on adaptive and self-adjusting fuzzy control principle is proposed for the speed regulation system of water pump. The simulation results show that the PMSM system controlled by the fuzzy PID controller is superior to the traditional PID control, and has better disturbance resistance, dynamic and steady performance.

Authors: Nazer Sisla , Bhat Sonal , Ramakrishna Ranjan , Vasudevarao Sunil Baikadi
Published: June 2023

Background: Intravenous cannulation is a prerequisite before any major or minor surgical procedures. Objectives: The rationale of the study was to compare the effectiveness of eutectic mixtures of local anesthetics (EMLA) cream and vapocoolant spray for pain reduction during intravenous (I.V.) cannulation. Methods: This observational prospective cohort study was done on 140 patients requiring I.V. cannulation prior to elective procedure who were divided into two groups, including group E: EMLA (eutectic mixtures of local anesthetics) cream and group V: Vapocoolant spray (ethyl chloride). Visual Analogue Scale (VAS) score, hemodynamic variables, and cost analysis were studied between the two groups. Statistical analyses were done using Mann-Whitney U test, unpaired t-test, Fisher’s exact test, and chi-square test were used to identify variation in pain scores between the two groups. Post hoc analysis was done at different time points by the Bonferroni test. P-value < 0.05 was considered statistically significant. Results: It was observed that the groups were comparable in terms of age, sex, and American Society of Anesthesiologists (ASA) physical status. A highly significant difference was observed between the two groups in terms of VAS scores for pain. There was also a significant difference in terms of heart rate and movement of hands during cannulation between the two groups. No changes were observed in the other hemodynamic parameters. Vapocoolant spray was also more cost-effective compared to EMLA cream with an occlusive dressing. Conclusions: Vapocoolant spray was a better tool compared to EMLA cream for intravenous cannulation, especially in emergency settings.

Background: The occurrence of lung ultrasound abnormalities in patients without lung disease remains uncertain, while patients with respiratory disease often exhibit such abnormalities. Objectives: The primary aim was to identify pathological ultrasonographic pulmonary findings and their correlation with baseline diseases and static lung compliance in patients without any pre-existing respiratory conditions. Methods: This prospective observational study enrolled a series of surgical patients with no history of pulmonary pathology (n = 104). Baseline diseases and patients' physical status classification, based on the American Society of Anesthesiologists (ASA), were documented by reviewing medical records. Prior to surgery, a lung ultrasound was performed to assess pulmonary changes. During surgery with general anesthesia, static lung compliance was measured. The Spearman correlation coefficient was employed to determine the correlation between the two variables. Results: Twenty-four patients (23.07%) exhibited 1 - 2 B-lines in certain lung fields. Seven patients (6.7%) had an ultrasound B-line score > 0 (indicating ≥ 3 B-lines). Among these patients, the average number of lung fields with ≥ 3 B-lines was 3.71 ± 2.43. Patients with systemic diseases (ASA ≥ 2) displayed a higher number of B-lines compared to ASA I patients (P-value = 0.039). Pleural irregularities were found in 10 patients (9.6%), while atelectasis and pleural effusion were observed in five (4.8%) and four (3.8%) patients, respectively. The mean lung compliance value was 56.78 ± 15.33. No correlation was observed between the total score of the B-lines and lung compliance (Spearman's correlation: rho = -0.028, P-value = 0.812). Conclusions: Patients without pulmonary pathology may exhibit ultrasound pulmonary abnormalities, which tend to increase with higher ASA scores and do not appear to have a correlation with static lung compliance.

Background: Areas with a higher prevalence of vitamin D deficiency have reported a higher frequency of severe coronavirus disease 2019 (COVID-19) infections. Objectives: This study aimed to assess the possible association between vitamin D and COVID-19. Methods: This study examined the vitamin D status, hepatic, serologic, and hematologic parameters of COVID-19 patients who tested positive upon admission to a major referral center in southwest Iran. A total of 50 cases and 50 controls were enrolled in the study after obtaining informed consent. The patients did not receive a vitamin D supplement during their hospitalization. Results: Patients with insufficiency and deficiency of vitamin D3 had a longer hospitalization time, a higher likelihood of ICU admission, and a greater risk of death compared to cases with sufficient levels of vitamin D. Conclusions: The results of this study showed that vitamin D deficiency is associated with increased severity and mortality rates. Therefore, using a vitamin D supplement may help reduce the severity of COVID-19.

Millî kültürün inşa edilmesinde ve şekillenmesinde önemli hizmetleri olan âşıklar, bu geleneğin yaşatılarak geleceğe taşınmasında müstesna rol oynamışlardır. Âşıklık geleneğinde destan ve halk hikâyeleri; millî kültürü ve tarihi yansıtması bakımından oldukça önemli bir mirastır. Manzum parçaların sıkça kullanıldığı bu edebi türlerin anlatılması, çok güçlü bir hafıza gerektirmektedir. Destan ve halk hikâyelerinin kuşaktan kuşağa intikal ederek günümüze ulaşmasını, âşıklara borçluyuz. Âşıklar; musiki, nazım, nesir ve tiyatro sanatı unsurlarını birleştirerek kendi sanatlarını icra etmişlerdir. 16.-17. yüzyıllarda Türk kültür coğrafyalarında altın dönemini yaşayan âşıklık sanatı, özellikle 19. yüzyılda pek fazla halk hikâyeleri ortaya çıkarmıştır. İrevan, Göyçe, Borçalı, Karabağ, Şirvan, Derbent muhitlerinin yanı sıra Karadağ-Tebriz, Urmiye, Horasan, Kaşkay, Zencan, Save gibi bölgeleri de kapsayan Azerbaycan âşıklık geleneği, Türk halk edebiyatının önemli bir kültür hazinesidir. 19. yüzyılda Azerbaycan âşıklık geleneğinin önemli merkezlerinden biri olan Göyçe, Azerbaycan Türk âşıklık geleneğine Ak Âşık (Allahverdi), Âşık Alı ve Âşık Alesker gibi dev üstatlar kazandırmıştır. Göyçeli Âşık Alı, 19. yüzyıl başlarında dünyaya gelen ve en uzun ömürlü sa-natkârlardan biri olarak bilinmektedir. Âşığın hayatı ve sanatsal faaliyeti ile ilgili en fazla bilgi, “Âşık Alı’nın Türkiye Seferi” adlı halk hikâyesinde yer almaktadır. Destan ve halk hikâyelerinde görülmekte olan farklı versiyon ve varyantlaşma, bu eser için de geçerlidir. “Âşık Alı’nın Türkiye Seferi”nin üç metni tarafımızca tespit edilmiş ve birbirine fazla benzemeyen bu eş metinler için çalışmamızda varyant terimi kullanılmıştır. Şimdiye kadar konuyla ilgili tek varyanttan bahsedilmiş ve ele aldığımız üç varyant arasında mukayeseler yapılmamıştır. Kullandığımız baskı yılına göre varyantlardan birincisi, Âşık İmran Hasanov ve Âşık Mahmud Memmedov; ikincisi, Âşık Hacı Bayramov; üçüncüsü ise Âşık Gulu tarafından anlatılmıştır. Çalışmamızda; Âşık Alı hakkında bilgi verilmiş, hikâyenin tanıtılması için Kiril alfabesiyle yayınlanan birinci varyantın ayrıntılı özeti çıkarılmıştır. Varyantlar, onları anlatan âşıkların adıyla adlandırılmış, her üç varyant arasındaki farklar ve yeni bilgiler tespit edilerek başlıca özellikleri açıklanmıştır. Varyantlar arasındaki farkları daha net görebilmemizi sağlaması ve hikâyenin önemli temel unsuru olan nazım parçalarını temsil etmesi adına “Ağrı dağı” şiiri, ayrıca incelenmiştir. Türkiye’deki Âşık İkbal (Yığval) ve Âşık Esmer’den bahsedilen hikâyede; Ağrı, Iğdır, Kağızman, Kars, Sarıkamış, Erzurum, Muş ve İstanbul gibi bölgelerin adı geçer. Eserde, Âşık Alı’nın; Yunus Emre, Karacaoğlan, Dadaloğlu, Pir Sultan Abdal, Âşık Ömer, Âşık Emrah, Öysüz Dede, Kayıkçı Kul Mustafa, Kul Mehmet, Kul Himmet, Âşık Hasan gibi üstatlardan haberdar olduğu ve onların şiirlerini ezbere bildiği görülmektedir. Bu doğrultuda çalışmamızın bir diğer amacı, “Âşık Alı’nin Türkiye Seferi” bağlamında 19. yüzyılda Azerbaycan ve Türkiye âşıklık geleneğinin yakın bağlarına dikkat çekmektir.
Safeguarding Intangible Cultural Heritage And Formal Education: Comparison of Policies Between Türkiye And Flanders (Belgium)
Authors: ARAL Ahmet Erman , VAN DOORSSELAERE Joris
Published: June 2023

The 2003 UNESCO Convention on the Safeguarding of the Intangible Cultural Heritage introduces a set of interrelated measures among which education is an intersection point. Since education is crucial to the transmission of intangible cultural heritage (ICH), the States Parties have focused their attention on connecting their activities to the education sector in recent years, with formal education making up the greater part of the efforts. Belgium and Türkiye both ratified the Convention in 2006 and education ministries in both countries or parts in it seem to have concentrated on secondary education (12-18 years old) to raise awareness of the meaning and importance of safeguarding ICH. The purpose of this paper is to compare and evaluate the Flemish and Turkish formal education systems at the secondary education level regarding the implementation of the Convention. Therefore, this qualitative research is based on the investigation of the policy texts and curriculum (mainly in Dutch and Turkish) that are explicitly or implicitly connected to the presence of ICH in the education systems of both cases. From this perspective, it takes the ratification of the Convention by both countries as its point of departure and presents three levels of discussion. First, in order to comprehend the present context wherein potential connections between ICH and education are established, the overall policy of Flanders and Türkiye is briefly outlined. Second, the discussion is directed to the implications these policy choices might raise. In the final section, the frame of discussion is further narrowed to the level of curricular choices. It can be stated that the analysis of the documents revolved around the implications of centrality (Türkiye) and relative autonomy (Flanders) to mobilize ICH in education. While in Türkiye, the course Folk Culture in secondary education was initiated on the national level as a direct response to the Convention, in Flanders, this safeguarding perspective did not seem to have permeated educational policy processes. However, the Flemish Government has tolerated an open curriculum framework that seems beneficial for the inclusion of relevant content on a regional or local level. Considering achieving connections with its specific teaching context, in both cases, attention has to be drawn to the role of teacher agency. It can be stated that teachers are in need of a balance between sufficient support (capacity building, instruction manuals, didactic suggestions, explicit references to ICH) and the autonomy to execute (open curricula, professional freedom).
