Authors: Yılmaz Demir Fadliye
Published: January 2025

Seramik üretiminin temelini oluşturan seramik şekillendirme teknikleri sanat, zanaat ve endüstri alanlarının önemli bileşenlerindendir. Mezopotamya, Çin, Japonya, Orta Asya, Anadolu ve Akdeniz gibi farklı coğrafyalarda uzun bir geçmişe sahip olan bu teknikler nesilden nesile aktarılarak günümüze kadar ulaşmıştır. Bu bağlamda değerlendirildiğinde özellikle Japon seramik şekillendirme teknikleri Uzak Doğu seramik geleneği içinde hem teknik hem de estetik açıdan önemli bir role sahiptir. Japonya’da MÖ 10.000’lerde Jomon Dönemi’nden kalma arkeolojik buluntular, ilk işlevsel ürünlerin elle şekillendirilmiş kil levhaların bir araya getirilmesiyle yapıldığını göstermektedir. Diğer elle şekillendirme teknikleri ise sonraki dönemlerde Japon seramik sanatında gelişmiş ve çeşitlenmiştir. Bu araştırma kökeni Orta Çağ Japonya’sına kadar uzanan ve Edo Dönemi’de (17.-19. yüzyıl) yaygın olarak kullanılmaya başlanan katı tek bir kil bloğunun içinin oyulmasını esas alan geleneksel Japon elle şekillendirme tekniği kurinukinin nasıl uygulandığı ve çağdaş seramik sanatındaki kullanımını konu edinmiştir. Tekniğin uygulama aşamaları örnek form uygulamaları üzerinden detaylı olarak anlatılmış, kil bloğunun şekillendirilmesi sırasında dikkat edilmesi gereken hususular belirtilmiştir. Genellikle çay seremonilerinde kullanılan seramik kapların üretiminde kullanılan kurinuki tekniğinin günümüzde işlevsel kapların yanı sıra sanatsal çalışmaların üretiminde de tercih edildiği görülmüştür. Sanatçılar kent mimarisi ve peyzajı, Orta Çağ ve modern zamanların birleşimi ve doğa gibi unsurlardan esinlenerek bunları çalışmalarına yansıtmıştır. Doğal ve organik görünümlerin elde edildiği kurinuki tekniğinde hiçbir eser birbirine benzemediğinden bu teknik sanatçılara daha kişisel ve özgün eserler yaratma olanağı sağlamıştır.

PRIORITIES AND PREREQUISITES FOR THE IMPLEMENTATION OF TAXATION MECHANISMS FOR TRANSACTIONS WITH CRYPTOASSETS IN UKRAINE
Authors: SEREBRIANSKYI Dmytro , BIRYUK Dmytro
Published: January 2025

Introduction. The rapid development of crypto assets has led to a transformation in the structure and functioning of individual components of the financial system. On the one hand, new opportunities are opening up for transactions, when payments and other financial services become cheaper, faster, and more accessible. On the other hand, the active use of crypto assets creates problems for financial stability as a result of "cryptoization". Understanding and streamlining the processes of cryptoization requires a deeper study of this problem in order to develop tools to influence it.

The purpose of the article is to study approaches to the taxation of crypto assets and to assess the potential potential for increasing tax revenues to the budget through the taxation of crypto asset operations.

Results. The article assesses the potential budget revenues from taxing income from crypto asset operations. It is determined that the introduction of a modern cryptocurrency taxation system is an extremely important step for maintaining the sustainability and innovation of the financial system in Ukraine. Effective taxation of cryptocurrency operations will contribute to attracting new investments, developing financial innovations and supporting innovative startups, preventing illegal cryptocurrency operations, stable growth of budget revenues, and ultimately – the stability of the financial system. The feasibility of introducing a tax rate of 5% of the profit from cryptocurrency operations is substantiated in order to stimulate cryptocurrency startups and attract investors.

Conclusions. The development of taxation of virtual assets should take place in the context of supporting constant financial innovations in conditions of limited information and focusing on ensuring tax flows to the budget. Conceptually, the dual functional nature of cryptocurrencies as investment assets and means of payment creates difficulties in fixing capital gains and losses when used as investment assets. As for the introduction of VAT and sales tax, it is advisable to classify cryptocurrencies similarly to the national currency. The effectiveness of collecting income tax will depend on the technologies for processing information about profits and losses and accounting for cryptocurrency transactions. In Ukraine, effective taxation of virtual assets will allow streamlining the processes of their circulation and ensuring their regulation at the state level, will provide a non-debt method of filling the budget, a more inclusive way of financing the reconstruction and development of the real sector of the economy, will contribute to maintaining the potential for creating capital markets and preserving the innovative nature of the development of the financial system.
STAGES AND FEATURES OF THE EVOLUTION OF THE ELECTRONIC TRANSACTIONS SYSTEM IN UKRAINE
Authors: SHEVCHUK Oleg
Published: January 2025

Introduction. The digitization of the economy has led to the development of a system of electronic transactions. All business communications, including monetary and commercial transactions, take place through electronic transactions. Ukraine, as a part of the global information space, has a common history of e-commerce development with other countries, however, there are other specific features of the electronic transaction system, which are determined by internal and external factors. Among the external factors, military and political instability has a fundamental influence on the national specificity of electronic transactions, which determines the relevance and demand for research in this area.

The purpose of the article is to identify the historical prerequisites for the formation of the electronic commerce system, which makes it possible to form the characteristic features of electronic transactions, as well as the financial and statistical trends of their formation in Ukraine with the aim of forecasting prospective directions of further development.

Results. The historical stages of the development of e-commerce within the conditions of the digitalization of the global economy were identified, which made it possible to follow the evolutionary emergence of the characteristic features of electronic transactions that are relevant to this day. The financial and statistical methodology of the study of evolutionary changes in the domestic system of electronic transactions was used, which confirmed the assumption of a radical transformation of electronic trade, electronic payments, the market of electronic money and cryptocurrencies as a result of the global coronavirus pandemic and the full-scale military invasion of Ukraine. Based on the study of the peculiarities of the formation of the Ukrainian market of electronic transactions, forecast trends for its further development were formed, which includes four directions of evolutionary transformations: infrastructure adaptation, development of computer and communication technologies, digitalization of the economy and Industry 5.0, European and global integration.

Conclusions. The national system of electronic transactions has undergone a long period of historical development as part of the economic, social, military and political development of Ukraine and the world. The study of the historical stages of the formation of the Ukrainian system of electronic transactions made it possible to predict promising trends in its development, which requires further scientific research in terms of adequate transformation of accounting, control and management of financial and economic activities of enterprises.
TAX POLICY OF UKRAINE UNDER MARTIAL LAW
Authors: PUKHALSKYI Vadym
Published: January 2025

Introduction. The article is devoted to the study of tax policy under martial law. The author establishes that the concept of “tax policy” is studied by many scholars, but currently there is no single view on the definition of its content. It is noted that the concept of “tax policy” is not enshrined in legislation. Tax policy is usually within the framework of a certain economic policy which, to one degree or another, subordinates all the most significant areas of social relations, including taxes. The author emphasizes that depending on the organizational structure of governance, tax policy is distinguished at the macroeconomic (state tax policy) and microeconomic levels (tax policy of taxable entities – legal entities and individuals). Each of these levels is characterized by its own specific features, purpose, goals, objectives and methods of their implementation.

The purpose of article is to develop tax policy measures that would support Ukrainian business.

Results. It is noted that the objectives of tax policy are not stable and depend on the economic situation in the country, social policy, and external conditions and threats faced by the State. We believe that it is appropriate to supplement the objectives of tax policy with one more – adaptation to the rules and regulations of the European Union.

The article establishes the dependence of tax policy goals and its models. The world experience distinguishes three models of tax policy: the policy of maximum taxes, the policy of economic development, and the policy of reasonable taxes. It is noted that none of the models is used in its pure form, but in combination, when one model prevails over the other.

Conclusions. The first days of the military invasion of Ukraine required the government to take adequate action on tax policy. In this regard, the author introduces the temporary martial law tax policy of Ukraine, which is characterized by certain simplifications and specific features which are manifested in five innovations. It is noted that due to the temporary tax policy, Ukraine has created favorable conditions for maintaining activity among existing business entities, helped the economy to overcome the first shocks of the war and save thousands of enterprises and millions of jobs.

The war has always been and remains an impetus for reforming tax policy, but at present its reform in Ukraine is complicated both from the economic side (lack of resources) and from the political side. Based on this, the author of the article proposes to introduce measures regarding tax policy that would allow supporting Ukrainian business in this difficult time for Ukraine.

Authors: ZABLOTSKA Rita , RUSAK Denys
Published: January 2025

Introduction. One of the key components of sustainable development is the green economy, which aims to reduce the negative impact on the environment, rational use of resources and ensure economic growth without harming the environment. This approach not only responds to global challenges such as climate change and the depletion of natural resources, but also opens up new opportunities for managerial and financial innovation.

Modern trends in the green economy include the introduction of new technologies, the development of environmentally friendly products and services, as well as the creation of effective mechanisms for reducing greenhouse gas emissions and waste management. The transition to renewable energy sources, optimization of production processes and improvement of energy efficiency are also important aspects.

Thus, understanding the current trends of the green economy is necessary for effective management and financing in new conditions. That is why modern studies of the key elements of these trends, their impact on management practices and financial strategies, as well as the opportunities and challenges facing organizations in the context of the transition to a green economy are relevant and necessary to ensure further economic growth.

The purpose of the article is to determine the current trends in the development of the green economy, taking into account financial and managerial aspects.

Results. The presented paper analyzes the main trends in the development of the modern green economy, presents the main features and differences from the traditional economy. The impact of managerial and financial aspects on the development of the green economy is determined. It has been proven that the managerial aspect of the green economy includes the development and implementation of strategies that not only meet the requirements of environmental standards, but also ensure competitiveness and long-term stability of business. At the same time, the financial aspect of the green economy covers the issues of investing in environmentally friendly technologies, financing projects that have a positive impact on the environment, and assessing the financial risks and opportunities associated with the transition to a green economy.

Conclusions. In the process of research, it was substantiated that sustainable development is not only a conceptual idea, but turns into a necessity for modern business and economic activity. The green economy offers new opportunities and challenges from both managerial and financial aspects, requiring companies to adapt and innovate. In general, the integration of green economy principles into management and financial strategies is a key factor for ensuring sustainable development and adaptation to changes in the global economic space. Successful implementation of these principles allows organizations not only to reduce their environmental footprint, but also to create new business opportunities, enhance reputation and attract sustainability-oriented investors.
Обзор достижений водоподготовки в области деферризации и деманганации подземных вод
Authors: Пропольский Д.Э.
Published: January 2025

Для обеспечения населения питьевой водой необходимо, чтобы качество очищенной воды соответствовало требованиям стандартов. Отсутствие надлежащего источника водоснабжения либо использование питьевой воды с превышением значений предельно допустимых концентраций загрязняющих веществ впоследствии наносят вред здоровью человека. Кроме того, возникает ухудшение работы систем водоснабжения в результате образования коррозии, отложений и закупорки труб. Одной из существенных проблем при водоподготовке подземных вод является повышенная концентрация железа (Fe) и марганца (Mn). Описаны существующие методы обезжелезивания и деманганации воды, условия их применения. Кроме того, проведен сравнительный анализ методов и рассмотрены перспективные направления в данной области. Установлено, что все существующие способы удаления железа и марганца имеют либо требуют этапа фильтрации. Использование в фильтрах каталитического слоя из модифицированных загрузок позволяет достичь более высоких показателей очистки и фильтрации, что обеспечит снижение затрат станций водоподготовки и стоимость очищенной подземной воды.

To provide the population with drinking water, it is necessary that the quality of purified water meets the standard requirements. The absence of an appropriate water supply source or the use of drinking water with exceeding the maximum permissible concentrations of pollutants subsequently harms human health. Besides, a deterioration in the operation of water supply systems occurs as a result of corrosion, deposits and blockage of pipes. One of the major problems of groundwater treatment is the increased concentration of iron (Fe) and manganese (Mn). The existing methods of iron and manganese removal from water and the conditions of their application are described. In addition, a comparative analysis of the methods is carried out and promising areas in this area are considered. It has been established that all the existing methods of iron and manganese removal either have or require a filtration stage. The use of a catalytic layer of modified media in filters provides for achieving higher purification and filtration rates that will reduce the expenditures of water treatment plants and the cost of purified underground water.

Authors: Wijaya Dhina
Published: January 2025

Abstract — The waste management in Kalurahan Guwosari is still facing significant challenges, with a system that is implemented in a modular fashion and lacks innovation, resulting in suboptimal utilization of residues. Every day, this region generates around 2.5 tons of waste, most of which is not properly managed, leading to accumulation at temporary disposal sites and environmental pollution risks. To improve this situation, the Kalurahan government has developed a web-based digital waste management application as an innovative solution. This application is unique because it not only offers real-time reporting and monitoring of waste but also includes interactive features that encourage active community participation, differing from other solutions that are often one-way. Utilizing the Waterfall method for development, the application has been tested using black box methods, yielding positive feedback from approximately 85% of users who feel the application is effective and has increased waste condition reporting by 60% compared to previous methods. It is hoped that this application will enhance community involvement in waste management, contribute to improving environmental quality, reduce the volume of unmanaged waste, and increase local awareness and income through waste reuse and recycling.

Published: January 2025

Electrochemical protonation, which can be realized in an electric-field-effect transistor with a gate layer consisting of a proton-conducting electrolyte Nafion membrane, offers a simple way of electrically tuning the physical properties of materials. In this study, we grew (010)-oriented epitaxial films of brownmillerite-structured SrCoO2.5 on various substrates whose lattice mismatch against SCO ranged from 0% to −2.9% by pulsed laser deposition and investigated the effect of substrate-induced strain on their protonation in field effect transistor structures with gate layers consisting of Nafion membranes. We found that the H concentration of the SCO films that were fully compressive-strained by up to 1.3% was ∼1.7 and that it was almost independent of the magnitude of the substrate-induced strain. We also found that the H content of the strain-partially-relaxed film with a residual compressive strain of 1.3% was lower, ∼1.3. These results indicate that lattice deformations arising from substrate-induced strain have insignificant effects on protonation, while lattice defects and dislocations introduced upon strain relaxation, which hinders proton diffusion in the films’ lattices, dominantly affect protonation in SrCoO2.5 films.

Chronic Low Back Pain and Sleep Disturbance in Adults in the US: The NHANES 2009-2010 Study
Authors: Zhou Hao-Yuan
Published: January 2025

BACKGROUND: Chronic low back pain (CLBP) is a significant health challenge with a high prevalence rate. Sleep disorders, which are prevalent among adults, have been linked with CLBP. However, the intricate relationship between sleep and pain adds complexity to our understanding of CLBP.

OBJECTIVES: To investigate the association between CLBP and sleep disorders, with a focus on the potential role of sleep disorders as a risk factor for CLBP.

STUDY DESIGN: Cross-sectional study based on publicly available data from the National Health and Nutrition Examination Survey (NHANES) for one cycle (2009-2010).

SETTING: The NHANES employs a complex, multistage probability sampling design to select a nationally representative sample.

METHODS: In this study, we included patients aged 20 to 69 years from the NHANES 2009-2010 cycle. After eliminating cases with missing data, a total of 863 patients remained. Baseline characteristics were analyzed by stratifying patients based on their CLBP status to assess initial inter-group disparities. Due to age imbalances between groups, we employed a 1:1 propensity score matching (PSM) method, reducing the sample to 508 patients. The association between CLBP and trouble sleeping was investigated following this calibration using a multivariate logistic regression analysis.

RESULTS: Upon categorizing the baseline characteristics of 863 patients based on CLBP, we identified that those within the CLBP group tended to be older and had a greater prevalence of health conditions, including cancer, hypertension, and cardiovascular disease (CVD). Notably, the prevalence of sleep disorders was higher in the CLBP group than in the non-CLBP group (P < 0.001). After implementing an age-based PSM for the 2 groups, 508 patients were selected from the initial 863 patients. After adjusting for various confounders using multivariate logistic regression, our analysis revealed a strong association between sleep disorders and an increased risk of CLBP.

LIMITATIONS: This is a cross-sectional study, and therefore causality cannot be established.

CONCLUSIONS: This study underscores the significant association between sleep disorders and an elevated risk of CLBP, highlighting the need for comprehensive management strategies that consider the role of sleep disorders in CLBP.

KEY WORDS: NHANES, chronic low back pain, sleep disturbance

Background: Acute kidney injury (AKI) is a major health problem in children worldwide. Intermittent Peritoneal Dialysis (IPD) has been reported as the preferred modality for the management of AKI in low-resource setting countries like Bangladesh. Its efficacy in different varieties of AKI is less emphasized. This study aims to assess the efficacy of IPD in pre renal and renal causes of AKI in children. Methods: This prospective, interventional study was conducted at Department of Paediatric Nephrology, Bangladesh Shishu Hospital and Institute from January 2020 to December 2021. Total 56 children aged between 1 month to 12 years of either sex, diagnosed as AKI stage 2 or 3 due to pre renal and renal causes who required IPD were included. All patients got IPD for 72 hours. Clinical and laboratory parameters were measured daily and compared between pre renal and renal group on day 3 to assess efficacy. Results: In the pre renal group, 65.4% of patients were infants while in the renal group, 51.9% were aged 1-5 years. After 3 days of IPD, oedema improved in both groups but in renal group, more patients were still oedematous (p<0.001). Serum creatinine, blood urea levels and urea reduction ratio improved significantly in both groups with greater changes in pre renal group (p<0.001). In the renal group, 29.63% patients required hemodialysis and 7.4% required further IPD, whereas all pre renal patients improved with a single course of IPD without hemodialysis. Conclusion: Intermittent Peritoneal Dialysis is more effective in the treatment of pre renal AKI in children.

Introduction

Uveal melanoma remains a disease with aggressive behavior and poor prognosis despite advances in clinical management. Because monotherapy with immune checkpoint inhibitors has led to limited improvement in response rates, combination with other agents that act on the biological basis of oncogenesis has been proposed as a possible therapeutic strategy.

Methods

We designed a phase 1b trial to test the safety and tolerability of selinexor in combination with immune checkpoint inhibitors in patients with advanced uveal melanoma. Patients received selinexor 60 mg PO twice weekly with standard of care, commercially available immune checkpoint inhibitor of the investigator’s choice. In one patient receiving nivolumab and ipilimumab as the immunotherapy backbone, selinexor 60 mg PO was given once weekly.

Results

We included 10 patients with uveal melanoma who received treatment with either selinexor plus pembrolizumab (n = 9) or selinexor plus nivolumab and ipilimumab (n = 1). The most common adverse events of any grade were neutropenia, thrombocytopenia, leukopenia, and anemia. Additional common nonhematological toxicities included hyponatremia, nausea, and vomiting. Dose reductions were required in six patients (60%). Among nine patients with evaluable disease, eight had stable disease as the best response. The median progression-free and overall survival were 6 months (95% CI: 4, not reached and 17 months (95% CI: 7, not reached), respectively.

Conclusion

The combination of selinexor and immunotherapy was safe and showed a side effect profile consistent with previous reports. Clinical benefit was achieved in most patients and should be validated in larger phase 2 trials. ClinicalTrials.gov ID: NCT02419495.

Проведено исследование вариабельности сердечного ритма у студентов и студенток, обучающихся на старших курсах вуза. Для изучения вариабельности сердечного ритма у студентов и студенток проводили запись электрокардиограмм в состоянии покоя. Получали последовательную серию из 50-60 кардиоинтервалов. По формулам рассчитывали параметры вариабельности сердечного ритма. Были изучены мода, вариационный размах и ряд индексов у лиц противоположного пола.
Было установлено, что практически все изученные параметры вариабельности сердечного ритма у лиц противоположного пола не имели статистически значимых различий. В то же время, у студентов отмечалась более продолжительная мода и более низкий индекс напряжения. С ростом номера курса и возраста у студентов и студенток обнаруживается минимизация половых различий в механизмах регуляции ритмической активности сердца. Это связывают с ростом парасимпатических влияний на работу сердца у лиц женского пола.

В работе изучалась длительность зубцов и интервалов у старшекурсников вуза, обучающихся по химическому профилю. Запись электрокардиограмм у обследуемых производили с помощью электрокардиографа «АрМаСофт-12-Кардио» в трех стандартных отведениях. Анализировали временные показатели элементов электрокардиограммы в трех стандартных отведениях.
Было выявлено, что у старшекурсников по большинству графоэлементов электрокардиограммы отсутствуют достоверные половые различия. В первом и во втором отведениях регистрировали статистически значимые половые различия по некоторым элементам электрокардиограммы, а в третьем они отсутствовали. С повышением курса обучения и возраста у обучающихся половые различия электрокардиограммы были менее выражены.

Endophytic fungi, particularly dark septate endophytes (DSE), have emerged as a promising and sustainable strategy for mitigating fungal pathogens in chili plants. Effective pathogen management is critical in chili production, as fungal infections can cause significant crop losses, reduce fruit quality, and decrease yield. While the use of endophytic fungi in plant protection has been explored in various crops, the potential of DSE as a biocontrol against fungal pathogens in chili plants remains unknown. The present study aimed to evaluate the effectiveness of DSE fungi as biological antagonists against significant pathogens that cause destructive diseases in chili plants, using in vitro trials. The study was conducted from December 2023 to March 2024 at the National Research and Innovation Agency (BRIN). A completely randomized design (CRD) was employed, with a single factor—DSE treatment. Three treatments included D0 (control), DSE 411, and DSE 471. Four pathogenic species were tested: Fusarium oxysporum (Fo), Phytophthora capsici (Py), Colletotrichum capsici (Cc), and Alternaria sp. (Alt). Inhibition rates (IR) were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test at a 5% significance level. The highest antagonistic activity was observed against C. capsici (Cc), with DSE 411 showing a mean value of IR of 77.54%, whereas DSE 471 exhibited a significantly higher IR of 90.26%. Macroscopic observations revealed the formation of clear zones around both DSE colonies, suggesting the mechanism of inhibition by antibiosis or the production of antifungal compounds. Microscopic analysis using scanning electron microscopy (SEM) revealed specific antagonistic mechanisms, including parasitism and competition, as key factors in pathogen suppression. These findings highlight the potential use of DSE fungi as effective biocontrol agents for managing major diseases in chili plants, offering a promising strategy for sustainable disease management and crop protection.
