Published: January 2023

Background: Signicant coronary artery lesions can be detected by evaluating regional myocardial
perfusion by Cardiac MRI (CMR). This study aims to determine the usefulness of this technique in
“known” patients of coronary artery disease (CAD). Our study aims at describing CMR featur Methods: es of CAD, including
CINE and perfusion imaging. Stress perfusion imaging with pharmacologic stress (Adenosine) was performed on 22 patients
with known CAD. These patients also underwent Catheter angiography (CAG). A total of 66 coronary territories were assessed
for perfusion abnormalities and corresponding CAG ndings. Regional wall motion abnormalities were Results: seen in
28(42.4%) coronary territories and regional myocardial thinning in 11(16%) territories. Hypokinesia (68%) was the most
commonly observed wall motion abnormality. Wall motion abnormality was present in most (91%; n=20) of the infarcted
territories and some (18.2%;n=8) of the non-infarct territories. Regional myocardial thinning was present in some of the
infarcted (27%; n=6) territories and none of the non-infarcted territories. The mean wall thickness in infarct territories was
5.1mm±0.4 and in non-infarct territories was 7.1mm±0.6. T2/STIR hyperintensity was present in 5 (23%) infarct related
coronary territories and none of the non-infarcted territories. In all 5 cases, MRI was done within 10 days of symptom onset. 32
(49%) coronary territories showed perfusion defect on stress imaging, with 23 (35%) of them showing a matched defect on rest
perfusion and 9 (14%) showing stress inducible perfusion defect. No perfusion defect was seen in 34(51%) territories. All 22
patients underwent CAG. 15patients had signicant disease (>70%) in a single vessel, 5 had in two vessels and none had in all
the three vessels.2 patients had non-occlusive coronaries (MINOCA). Using CAG as gold standard, the sensitivity of stress
perfusion CMR in detecting signicant CAD in non-infarct territory in these patients was 70%, with a specicity of 94% and
accuracy of 88.3%. Visual analysis of rst-pass gadolinium CMR perfusion images to detect reg Conclusion: ional myocardial
perfusion defect has a moderate sensitivity and high specicity for diagnosing signicant obstructive CAD in non-infarct
related coronaries, as compared to CAG.
A COMPARATIVE STUDY BETWEEN CAUDAL ROPIVACAINE AND ROPIVACAINE PLUS DEXAMETHASONE FOR INFRAUMBILICAL SURGERY IN PEDIATRIC PATIENTS
Authors: Sithara Jebin , Badole Usha
Published: January 2023

Background: Caudal block is one of the most popular regional block in children with high success rate
for infra-umbilical surgeries. Among local anaesthetics ropivacaine provides a greater margin of safety,
less motor blockade, less neurological and cardiac toxicity and similar duration of analgesia compared to bupivacaine.
Addition of dexamethasone as an additive to local anesthesia decreases the postoperative rescue analgesia
consumption.This study was designed to compare the effectiveness of intra-operative and postoperative analgesia on adding
dexamethasone to 0.15% ropivacaine with 0.15%ropvacaine given alone. A prospective double blinded Materials:
randomised controlled study was conducted consisting of 60 patients undergoing infra-umbilical surgeries under general
anesthesia with Caudal block. Patients were randomised into two groups. Group A received 0.15% Inj.ropivacaine 1.5ml/kg
with 1ml normal saline and Group B received 0.15% Inj.Ropivacaine 1.5ml/kg with 0.1mg/kg Inj.dexamethasone in caudal
block Results: Mean FLACC pain score was comparable and statistically not signicant (P=0.083) in both groups upto 30min
postoperatively. At 60min mean pain score in group A was 0.30 ± 0.54 and in group B was 0 (P=0.005) which was statistically
signicant. In group A 40%(12) patients required rescue analgesia whereas in group B only 10%(3) patients required
analgesia(P= 0.007) Patients remained hemodynamically stable throughout the procedure. After 60min Conclusion:
postoperatively FLACC score was signicantly higher in group A as compared to group B. It concludes that addition of
dexamethasone signicantly reduced postoperative pain and need for rescue analgesia without any side effects.

Cardiovascular complications in COVID-19 include deep vein thrombosis, stroke, angina, myocardial
infarction, heart failure and cardiogenic shock.ECG changes including sinus tachycardia, sinus
bradycardia and atrial brillation . Incidence of cardiovascular complications is directly linked to severity of disease which in
turn correlate with inammatory markers including CRP, LDH, Ferritin, D Dimer and IL-6. Raised Inammatory markers also
suggest poor outcome of patients. Therefore it is advisable to do inammatory markers in admitted patients for management.
Followup study at 3 and 6 months revealed new onset cardiovascular complications while no new complications were
documented at 12months follow up.Thus regular health checkup is recommended post COVID infections for atleast 6months.

Breast cancer develops when cells in the breast tissue begin to grow in an uncontrolled manner. These cells usually form a tumor that can often be
seen in an x-ray or felt as a lump. Tumors are often unresponsive to normal physiological stimuli. At the center of a tumor are typically dead or dying
cells that produce biomarkers that can be analyzed for the presence of the tumor. In the last ten years, various new drugs have been introduced in the
international markets to treat breast cancer tumors. These drugs are administered either orally or via an injection. In this review, an insight is
provided into the different signal transduction pathways that are being targeted for the for adjuvant breast cancer treatment by the use of hormoneblocking agents, chemotherapy and monoclonal antibodies.

В якості математичних моделей вібрацій вузлів генераторів вітроустановок пропонується використати лінійні процеси авторегресії (AR) та авторегресії-ковзного середнього (ARMA). Такі процеси відносяться до лінійних випадкових процесів з дискретним часом, які мають безмежно-подільні закони розподілу. Особливостями таких процесів є те, що коефіцієнти авторегресії та ковзного середнього безпосередньо пов′язані з ядром лінійних випадкових процесів з дискретним часом. Приведено властивості ядер лінійних AR та ARMA процесів, параметри яких запропоновано в якості діагностичних ознак, та способи їх оцінки. Важливою властивістю ядер лінійних AR та ARMA процесів це їх рекурентний зв′язок з параметрами авторегресії та ковзного середнього. Це дає можливість побудувати рекурентні алгоритми оцінки ядер лінійних випадкових процесів з дискретним часом. Показані приклади оцінки ядер лінійних процесів авторегресії різних порядків. Як приклад використання запропонованого підходу розглянуто вібраційний сигнал обертового вузла підшипника кочення генератора вітроустановки USW 56-100 з боку корпусу головного валу встановленого на стенді для випробувань вітрогенераторів. Швидкість обертання головного валу 72 об/хв. Для досліджень вібраційних сигналів використовувався розроблений в ІЕД НАН України прототип системи діагностики вітрогенераторів за допомогою якого була проведена реєстрація вібраційних сигналів та отримані оцінки ядер лінійних випадкових процесів. Приведені результати оцінки ядер вібраційних сигналів підшипникового вузла генератора вітроустановки, що встановлений на дослідницькому стенді. Використані різні критерії оцінки параметрів авторегресії, а саме, кінцевої похибки прогнозу (FPE), та критерій Хенна –Квіна (HQ). Показані деякі параметри ядер лінійних AR процесів, що можна використати в якості діагностичних ознак технічного стану вузлів генераторів вітроустановок ,а саме , де ядро лінійного випадкового процесу AR або ARMA. Показані результати оцінок даного параметра для різних AR процесів, що відповідають різним методам оцінки характеристик таких процесів.
АНАЛІЗ СТАТИЧНИХ ХАРАКТЕРИСТИК ВІДЦЕНТРОВОГО РЕГУЛЯТОРА РОТОРА ВІТРОУСТАНОВКИ ПРИ АНТИФЛЮГЕРНОМУ РЕГУЛЮВАННІ
Authors: Golovko V. , Kokhanevich V. , Shykhailov M. , Marchenko N.
Published: January 2023

Сучасні вітроустановки (ВУ) повинні надійно та безпечно функціонувати в широкому діапазоні швидкостей вітру, що потребує їх обладнання засобами регулювання обертів та потужності. При цьому в ВУ малої потужності пріоритетним є регулювання поворотом лопаті навколо її вісі в використанням відцентрові регуляторів, що зарекомендували себе як одні з найбільш простих та надійних засобів регулювання. Проектування даних регуляторів для ВУ має свою специфіку і повинно враховувати крім параметрів самого регулятора також параметри ротора. Запропоновані Г.Х. Сабініним математична модель відцентрового регулятора для флюгерного регулювання та співробітниками Інституту відновлюваної енергетики НАН України математична модель для антифлюгерного регулювання дозволяють розробникам визначити параметри відцентрового регулятора при його проектуванні.

В даний час технологічні можливості виготовлення лопаті дозволяють отримати профіль лопаті максимально наближений до розрахункового, тобто розширення лопаті від кінця до комеля до 1:4 і закруту до 30°, що потребує врахування кута між хордою лопаті і її вектором моменту інерції. В ряді робіт були запропоновані математичні моделі для флюгерного та антифлюгерного регулювання з урахуванням даного кута. Проведений в даній роботі аналіз статичних характеристик відцентрового регулятора ротора вітроустановки при антифлюгерному регулюванні за різних кутів між хордою лопаті і вектором її моменту інерції показав, що даний параметр впливає на точність регулювання і його необхідно враховувати при розрахунку параметрів регулятора. Так різниця в обертах регулятора для лопатей, коли кути між хордою та моментом інерції складають 0° та 20° та з урахуванням діапазону регулювання в 20°, складе 9%. При налаштуванні регулятора на номінальні оберти для його узгодження з аеромеханічною характеристикою ротора для ефективної роботи вітроустановки також є необхідним врахування кута між хордою лопаті і її вектором моменту інерції. Так відхилення від номінальних обертів регулятора і, відповідно, ротора без урахування закруту лопаті в 10° буде складати 8,3%, в порівнянні з лопаттю що немає закруту. Бібл. 12, рис. 10.

Published: January 2023

Завдяки екологічним перевагам вітрові технології та їх широке застосування є одним із перспективних сучасних напрямів генерації електричної енергії. У роботі представлено результати теоретичних і прикладних досліджень щодо впливу параметрів вітрового потоку регіону Полісся на вибір характеристик автономної системи електропостачання на основі вітроелектричної установки.

Зокрема, виведено аналітичні залежності для визначення: потужності вітрового потоку, коефіцієнта використання енергії вітру, електричної потужності, що розвивається вітроенергетичною установкою, та середньорічної кількості часу роботи установки. 

Прикладні дослідження відображені в графічній залежності коефіцієнта використання енергії вітру від швидкохідності вітрового колеса та залежності потужності вітроенергетичної установки і коефіцієнта використання енергії вітру від швидкості вітру. Також відповідно до номограми розподілу середньої швидкості вітру по місяцям за період з 2011 до 2021 року та відповідно до номограми щомісячної частини вітрів, придатних для потреб вітроенергетики, обґрунтовано вибір вітроелектричної установки малої потужності.

Використовуючи методи статистичного розподілу, а саме розподіл Релея, нормальний розподіл, за середнім значенням параметра (швидкість вітру) та емпіричну функцію розподілу, досліджено щільність імовірності швидкості вітру. Встановлено, що застосування розподілу Релея дозволяє підвищити точність обчислення на 18,8 % і 36 % в порівнянні з нормальним розподілом і розрахунком за середнім значенням швидкості вітру відповідно. За 100 % було прийнято значення енергії, отримане розрахунком за емпіричними даними. Під час розрахунків мали місце похибки, спричинені нерівномірністю добового використання енергії споживачем та імпульсним характером надходження енергії. З метою уникнення зазначених похибок надалі рекомендовано використовувати математичне та комп'ютерне моделювання.

Отримані розрахунки параметрів елементів системи автономного електропостачання на основі вітроенергетичної установки, адаптованої до характеристик вітрового потоку регіону Полісся, свідчать про можливість забезпечення в даному регіоні надійного та безперебійного постачання споживачам електричної енергії.

Authors: AYAS Selahattin , UÇAN Anıl
Published: January 2023

Introduction: This study aims to investigate sleep-related disorders and their possible causes after COVID-19 infection.

Material and Methods: The data of patients over the age of 18 with a history of COVID-19 infection who applied to our Sleep Disorders Unit in the last 3 months were obtained retrospectively from anamnesis, laboratory, imaging, and polysomnography examinations. The data of Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale and Beck anxiety inventory (BAI) tests of patients were included in the study.

Results: After COVID-19 infection, in all patients, reason for admitting to our Sleep Disorders Unit was complaints of insomnia. Another sleep-related disorder was determined in 64% of the patients (Obstructive Sleep Apnea Syndrome (OSAS) is the most common with 52%). The history of the chronic cardiorespiratory, cerebral, endocrine-metabolic disease was significantly higher in patients having complaints of insomnia and another accompanying sleep-related disorders (68% vs 0%, p=0.001). Also, the history of hospitalization in these patients was higher, although not significant(50% vs 11%, p=0.088). For all patients, the median BAI value and the mean PSQI value were high (13 and 11.6, respectively), but no correlation was found between them (p=0.336).

Conclusions: The most common reason for sleep-related admission after COVID-19 infection is complaints of insomnia and if there is a history of chronic cardiorespiratory, cerebral, endocrine-metabolic disease and/or hospitalization because of COVID-19 infection, another accompanying sleep-related disorders, especially OSAS, should investigate. Also, the severity of anxiety disorder as a cause of insomnia complaints is not correlated with the deterioration in sleep quality.

Authors: ESME Hıdır
Published: January 2023

Giriş: Yelken göğüse neden olmayan multipl kot kırıkları için cerrahi endikasyonlar konusunda küresel bir kılavuz veya fikir birliği yoktur. Çalışmadaki amacımız, yelken göğüs dışı nedenlerle kot stabilizasyonu uygulanan hastalar ile konservatif tedavi uygulanan hastaların sonuçlarını karşılaştırmaktır.

Gereç ve Yöntem: 2010 Ocak ile 2021 Aralık ayı arasında künt travma sonrası kliniğimize başvuran, multipl kot kırığı saptanan 53 hasta çalışmaya dahil edildi. Kot stabilizasyonu yapılan hastalar grup 1, konservatif tedavi uygulanan hastalar ise grup 2 olarak kabul edildi. İki grup yaş, cinsiyet, travma nedeni, fraktür sayısı, eşlik eden pulmoner yaralanmalar, eşlik eden toraks dışı yaralanmalar, tüp torakostomi takip süresi, intravenöz analjezik kullanım süresi, kan transfüzyon miktarı, hemoglobin düzeyinde azalma miktarı, yoğun bakım yatış süresi, hastane yatış süresi, pulmoner komplikasyonlar ve mortalite açısından karşılaştırıldı.

Bulgular: Kot stabilizasyonu uygulanan 17 hastada cerrahi endikasyonlar: 6 hastada parankim yaralanması ve masif hava kaçağı, 5 hastada clotted hemotoraks ve akciğer ekspansiyon kusuru, 3 hastada deplase segmentin 15 mm’den fazla olduğu multipl kot kırığı, 2 hastada intravenöz analjezik tedaviye rağmen şiddetli ağrı ve 1 hastada göğüs kafesinde volüm kaybına neden olan multipl kot kırığı idi. Kot stabilizasyonu yapılan hastalar ile yapılmayanlar arasında intravenöz analjezik kullanım süresi, yoğun bakım ve hastane yatış süresi açısından anlamlı fark vardı. Ancak tüp torakostomi takip süresi, kan transfüzyon miktarı, hemoglobin düzeyinde düşme miktarı, pulmoner komplikasyon ve mortalite açısından anlamlı fark saptanmadı.

Sonuç: Multipl kot kırıklarının cerrahi stabilizasyonu intravenöz analjezik kullanım süresi, yoğun bakım ve hastane yatış süresini azaltan güvenli ve etkili bir prosedürdür.
Existência em crise: as situações-limite em Karl Jaspers
Authors: Brea Gerson , Kabashima Hiroshi
Published: January 2023

Querer investigar, num curto ensaio, as diversas facetas das situações-limite, bem como suas consequências para a existência humana, revelaria uma pretensão descabida. O que intencionamos aqui é simplesmente explorar, a partir de indicações fornecidas por Karl Jaspers, alguns momentos que as constituem. Optamos por nos aproximar do tema a partir de cinco perspectivas: o limite, o sentido, o nada, o sofrimento e a finitude. Em o sofrimento, empreenderemos uma breve crítica textual de passagens de duas obras centrais de Karl Jaspers: Psychologie der Weltanschauungen, de 1919, e Philosophie, de 1932. Perceberemos aí uma modificação no modo como o sofrimento é apresentado. Embora sutil, essa alteração leva-nos não somente a precisar o papel das situações-limite na filosofia da existência jaspersiana, mas também a vislumbrar uma tensão entre situações-limite e experiências com situações-limite.
Jacques Rancière e o sujeito dos direitos do homem
Authors: Sahd Luiz Felipe
Published: January 2023

Neste artigo discuto a proposta de definição do sujeito dos direitos do homem no pensamento de Jacques Rancière. Inicialmente, examino a crítica de Rancière de que Arendt despolitiza os direitos humanos em função de seus pressupostos aristotélicos. Depois, explico como Rancière reconceitualiza a relação entre o humano e o político para entender a política de direitos humanos em termos estratégicos e não existenciais. Argumento que fornece uma base mais adequada para a compreensão da política de direitos humanos do que a concepção de política de Arendt. Desta maneira, Rancière nos permite ver as disputas pelos direitos humanos como parte integrante das lutas sociais que são o cerne da vida política, uma vez que envolvem a promulgação da igualdade em condições de desigualdade.
O entrelaçamento crítico da história: a historicidade como crise fenomenológica e existencial nas obras de Merleau-Ponty
Authors: Davis Duane H.
Published: January 2023

As considerações de Merleau-Ponty sobre a historicidade são significativas, tanto como um relato fenomenológico, quanto como um relato existencial de nossa situação histórica. Naturalmente, estes aspectos de seu trabalho não se excluem mutuamente, mas se entrelaçam. E cada aspecto contribui para o sentido da crise da historicidade humana. Primeiro consideraremos a crise fenomenológica da historicidade – ou seja, consideraremos a crise da historicidade fenomenologicamente. Esta é a tentativa de revelar as condições da possibilidade da história a partir da história ou da estrutura de nossa situação histórica – onde a posição de Merleau-Ponty se afasta da fenomenologia husserliana. Em seguida, consideraremos a crise existencial de historicidade – ou seja, consideraremos a crise de historicidade existencialmente. Esta é a tentativa de compreender o imperativo de que as coisas são importantes para nós historicamente. Finalmente, vamos indicar brevemente a importância destes aspectos de nossa historicidade como um entrelaçamento crítico. Este entrelaçamento crítico revela a intrusão mútua do “como” e do “porquê” de nossa historicidade, que Merleau-Ponty descreve no final de sua carreira como uma existência chiasmática dentro da carne do mundo. O cruzamento crítico como interrogatório de nosso ser histórico fornece o “quem”, “o quê”, “quando” e “onde” de nossa historicidade.

Published: January 2023

With the existence of digital technology, the phenomenon of viral products in Indonesia is increasingly widespread, not only manufactured products, traditional products, or home products can also become viral because of this technology. The Sidayu (Bonggolan) traditional MSME products are no exception, which some time ago went viral on social media and then spread to the people of Gresik Regency and its surroundings. This research is very interesting to study, to study online consumer behavior towards product repurchase intentions which are characterized by theoretical studies that Viral Marketing, and Product Innovation influence purchase decisions and repurchase intentions while purchasing decisions are intermediaries. This type of research is explanatory research with a quantitative approach. The number of samples was 200 participants spread across Gresik Regency who had repeatedly bought this traditional food product. This study uses SEM analysis with the help of SmartPls software. The findings show that viral marketing and product innovation directly influence purchasing decisions, but the findings directly show insignificant results on repurchase intention. Interestingly, the findings of this study indicate that there is a significant indirect effect of viral marketing and product innovation on repurchase intention through the mediation of purchase decisions.

El objetivo principal del presente artículo es dar cuenta de ideas específicas sobre el lugar que ocupan las Humanidades en el contexto de la globalización, y cómo éstas han luchado por mantener, durante lo que va del siglo XXI, un espacio y un prestigio que hoy parece verse cuestionado por la lógica operativa del corporativismo a nivel mundial. Este último al parecer tiene un método de entendimiento del mundo cuyos discursos crean imperativos y significados que lo benefician, y para ello se ha incorporado el discurso empresarial en la agenda de los programas educativos por competencias, que terminan ignorando la importancia de instituciones tradicionales y legados intelectuales como el conocimiento humanístico. Es necesario recordar que las Humanidades tuvieron un lugar preponderante en la historia de la era moderna, y que debemos de actuar para que continúen presentes en la reorganización de los métodos de entendimiento de la realidad.

Published: January 2023

Public services in the village are very important because the village is the smallest part of the administrative government system in Indonesia and is the front line of public services. Technological developments encourage the government to manage public services to improve the ineffective bureaucratic paradigm. E-government is a solution to improve public services. One of the failures in implementing E-Government is the village government's lack of readiness to adopt information technology. The research method used in this research is descriptive qualitative. The results obtained suggest that the STOPE framework model consisting of Strategy, Technology, Organization, People, and Environment is the most appropriate model to analyze the readiness of the village government. Of the 5 domains that were assessed, 3 domains received the Very Ready predicate and 2 domains received the Ready predicate

Batik has unique motifs that are very diverse so it is difficult to recognize the in certain classes. This research was conducted to classify coastal batik, especially Tegal batik, Pekalongan batik, and Cirebon batik so that it can help facilitate the introduction and understanding of coastal batik when compared to another batik, such as Yogyakarta batik. The method used is Grey Level Co-occurrence Matrices to extract texture features, while, to determine the proximity of the test image to the training data using the K-Nearest Neighbor method, the calculation of the distance to be used is the Euclidean Distance and Manhattan Distance based on the texture characteristics of the batik image obtained. In this study, the highest score was obtained at 64% for Euclidean Distance and 66% for Manhattan Distance at k=15

With the emergence of Repositories of Learning Objects, and for a more efficient use of them, different search engines have been developed that allow users to easily and effectively find the materials they need. There are many engines that are based on keywords, but these limit the search area, some based on ontologies and others like the one used, based on the metadata that describe learning objects. A very powerful engine is SOLR, this is based on the LUCENE library, which runs as a Web application in Java, allowing documents to be sent to be indexed via HTTP and consulted using HTTP GET requests. The experiments carried out with the tool implemented based on this engine demonstrate the efficiency and quality of the results with respect to the other engines.

With the arrival of the Internet, people have changed the way they communicate, the ways of doing business and operating the companies, because globalization requires constant evolution. Thus, with the rise of electronic commerce at an international level and the use of information and communication technologies (ICT), SMEs try to adopt them in order to take advantage of the advantages they offer and adapt to constant changes in the technologies. However, the literature related to the use of ICT in terms of marketing practices and financial benefits that leads to companies, does not seem to be enough, representing an obstacle to its adoption and application. A bibliographic analysis is presented, reviewing from scientific articles, magazines and books from different databases such as Ebsco, Emerald, Redalyc, Elsevier and Gale Cengage Learning, to know the state of Mexican SMEs. It was found that the interaction causes a multidirectional communication, so developing marketing strategies in social media is mandatory, as is investing in these technologies to thrive.
Public-Private Partnership and Risk Management in Healthcare System
Authors: Japarova Damira
Published: January 2023

The lack of financial resources in public health organizations of the Kyrgyz Republic requires the involvement of private sources of funding. Private sector involvement can take place in the construction and operation of hospitals, clinics, laboratories, and other health facilities. A prerequisite for public-private partnership is the joint financing of projects. At the same time, possible risks are shared between project participants. One of the risks is the risk associated with the unpredictability of demand for services. The emergence of partnerships that provide high-quality medical services requires a preliminary identification of risks and their effective distribution among the participants in a public-private partnership. The next type of risk is determined by such economic factors as changes in bank interest rates on loans, exchange rates, inflation rates, tax rates, which ultimately can limit the amount of credit resources and, accordingly, expected income. Risk management in a public-private partnership involves the definition of risks as expected losses associated with an increase in costs not provided for in the project, as well as a discrepancy between the expected financial results planned in the forecasts of the public-private partnership. The paper gives a description of the types of risk, the principles of their prediction and prevention.
Environmental Kuznets Curve Hypothesis: The Case of Central Asian Countries
Authors: Çağlayan Akay Ebru , Oskonbaeva Zamira
Published: January 2023

This study aims to explore the validity of environmental Kuznets curve hypothesis in case of Central Asian countries. For this purpose, annual data of selected countries for the period 1993-2018 was utilized. Environmental Kuznets curve (EKC) hypothesis implies that the environmental quality deteriorates at the beginning of economic growth and improves over time. The existence of this hypothesis has been evaluated by employing panel ARDL (autoregressive distributed lags) model. The findings indicate the validity of the N-shaped EKC hypothesis in the case of the Central Asian countries. Moreover, renewable energy consumption improves the environmental quality by reducing CO2 emissions. These outcomes have practical policy implications for the government and policymakers of the studied countries. The appropriate recommendations for designing a regional energy policy that is both inclusive and environmentally friendly were suggested.

Published: January 2023

The history of money reveals a pattern: there has been a trend of money dematerialization over the centuries. The majority of money now circulates in electronic form. Banks, governments, and institutions are analyzing and researching the economic and technical viability of implementing digital money, as well as the implications for monetary and fiscal policy. Digital currencies are essentially e-cash that does not require any specific encryption technologies. The financial system has the potential to be transformed by digital money, and the digital money revolution will take place on a worldwide scale. Cryptocurrencies are digital currencies that encrypt and verify network transactions using cryptography. Cryptocurrencies like Bitcoin could be the future of payment systems or even how we exchange value over the Internet in the coming years. Bitcoin has the potential to be a revolution because it provides people with a new level of sovereignty and, as a result, a new form of freedom, and it represents an alternative to our current financial system. Most central banks, on the other hand, are experimenting with central bank digital currencies (CBDCs). A CBDC is a digital currency that is issued by a central bank and is widely used. Thanks to the enormous labor and attention that central banks are spending to digital currencies, they will soon become a reality. We present and discuss the characteristics of digital currencies and crypto currencies in this study, as well as the digital currencies used by central banks (CBDCs) and open issues.
The Foreign Debt and Economic Growth in Sub-Saharan Africa

Published: January 2023

The growing levels of external debt in developing countries are increasingly a worldwide problem, particularly in Sub-Saharan African countries, where the expanding portfolio of foreign debts, debt servicing rates, and debt overhang cause alarm and global concern. The likelihood of relatively good outcomes of the interaction between external debt and economic growth is based on the government's attempts to maintain a sustainable debt-to-GDP ratio, a low budget deficit, and that the external debt is utilized primarily for capital investments. Under other conditions, the government would confront a circumstance in which accumulated foreign debt levels stifle economic progress, particularly when debt levels rise over time and are poorly managed. In this context, this study aims to examine the association between foreign debt and economic growth in Sub Sahara African countries during the period from 1980 to 2019. The study employed the Dynamic Panel Threshold Regression analysis to investigate the differential impact of foreign debt on economic growth below and above a threshold. The empirical results highlight the existence of a nonlinear relationship between foreign debt on economic growth above the debt threshold during the examined period. Empirical evidence suggests significant policy prescriptions; Sub Sahara African governments should use solid methods of generating domestic income to supplement outside sources of funding, such as the inclusion of domestic informal businesses on a shared cutting-edge platform to ensure successful domestic revenue collection.
Foreign Trade and Hysteresis Effect: An Essay on Foreign Trade Flows in the Turkish Economy
Authors: Algan Neşe , Bal Harun , Yıldırım Koray
Published: January 2023

There is a wide literature that temporary shocks in real exchange rates and volatility will cause structural breaks in foreign trade. As a result of temporary shocks in real exchange rates, the real exchange rate elasticity of imports decreases. The decrease in the sensitivity of the import volume to real exchange rates and the failure to return to its former levels after the temporary shock is expressed as the hysteresis situation. In case the exchange rates return to their previous levels after the temporary shock, the main dynamic of hysteresis is that the firms exhibit the behavior of staying in the market due to sunk costs. In the study, foreign trade flows in the Turkish economy were analyzed for the period 2003Q1-2021Q2 by using the asymmetry hypothesis in order to test the hysteresis effects. According to the findings obtained from the asymmetry hypothesis, the absence of a decrease in the import volume during the period of depreciation of the domestic currency indicates the existence of the hysteresis effect. The fact that the firms exhibited the behavior of staying in the market in exchange rate depreciation in the Turkish economy means that sunk costs are extremely effective in hysteresis. Based on this information, as a solution to the hysteresis effects in foreign trade flows in the Turkish economy at the point of policymaking, reducing the sunk costs in market entry to reasonable levels and ensuring stability in exchange rates come to the fore as suggestions in terms of hysteresis.
Attempts to Collect Environmental Approaches under the Sustainable Development Concept
Authors: Bağlıtaş H. Hilal
Published: January 2023

Environmental awareness has particularly increased in the last twenty years. Besides most of the researchers focusing on the environmental Kuznets curve, the approaches relevant to environmental degradation are not limited to disposable income. The paper has theoretical approaches and puts forth all possible sources of pollution and degradation based on sustainable development dimensions. In this respect, free riders and the tragedy of the commons are on the social side. The Environmental Kuznets curve and pollution haven hypothesis are on the economic side. Moreover, entropy is the third law of thermos-dynamic and creates the physical basis for environmental deterioration. In addition, at the end of the process, the Anthropocene emerges because of these four issues. It declares the inevitable consequences of worldly human activities on the naming of ages. Political suggestions might require local, regional, and global support, solutions, and regulations because of multiple dimensions and scales. Public awareness, the seriousness of companies in fulfilling their responsibilities, and the interaction of countries can make a difference in a more sustainable today and tomorrow.
Do Economic Integrations Improve E-Commerce Performance in Member States? A Study on the European Single Market
Authors: Savrul Mesut , İncekara Ahmet
Published: January 2023

Many of the international trade theories hold the view that reducing the barriers to foreign trade will result in an increase in welfare in all the countries that are party to the trade. The regional integrations established in different parts of the world in the period following the Second World War enabled this theory to be translated into practice, at least on a regional basis. The European Single Market, which was founded in 1993, is significantly different from the economic integrations established in the aforementioned period by incorporating many innovations. One of these innovations is that the Digital Single Market strategy pursues to guarantee better access for customers and enterprises to online goods and services across Europe, which was put into effect in 2015.
The contribution of economic integrations on e-commerce performance of the member countries has been examined in the context of the European Single Market in this study. In the study, e-commerce statistics of the European Single Market countries covering the years 2010-2021 and the Digital Economy and Society Index covering the years 2017-2022 were used. The data is collected from Eurostat, Benchmarking Digital Europe and European Commission, Digital Scoreboard databases. The results of the study present that the Digital Single Market Strategy has contributed to the less developed countries of the Single Market rather than the developed countries.
The Effect of Foreign Direct Investments on Unemployment: The Case of Turkey
Authors: Süt Ali Talih , Yüksel Özge
Published: January 2023

Many studies in the literature focus the positive contribution of foreign direct investments, especially in the economic growth process of developing countries' economies. However, there is no consensus on the effects of foreign direct investments on unemployment yet. Accordingly, in this study, the short and long-term relationships between foreign direct investment and unemployment in Turkey between the years 1988-2020 were examined. The findings of the study confirmed the views in the literature that "the effect of foreign direct investments on unemployment is positive", in other words, "direct foreign investments increase unemployment". In addition, according to the Granger causality analysis results, a one-way causality relationship from unemployment to foreign direct investments was observed. Considering the policies followed by Turkey after the January 24 decisions, foreign direct investments are not an element that can be easily abandoned for the country, as it increases the domestic production volume, implements technological innovations, and sets an example for domestic formations in many aspects. Additionally, it is thought to be at a very important point in terms of ensuring integration with the outside world. In this context, the study points out that in addition to encouraging foreign direct investments within the scope of stable growth, domestic investors should be supported in terms of the consistency of employment policies.
