Authors: Nan Lingbo , Wang Yumeng , Chen Diyi , Huang Weining , Zhu Zuchao , Liu Fusheng
Published: May 2023

Traditional centrifugal pump performance prediction (CPPP) employs the semi-theoretical and semi-empirical approaches; however, it can lead to many prediction errors. Considering the superiority of deep learning when applied to nonlinear systems, in this paper, a method combining hydraulic loss and convolutional neural network (HLCNN) is applied to CPPP. Head and efficiency were selected as two variables for demonstrating the energy performance of the centrifugal pump in order to reflect the prediction ability of the proposed model. The evaluation results indicate that the predicted head and efficiency are accurate, compared with the experimental results. Furthermore, the HLCNN prediction model was compared against machine learning methods and the computational fluid dynamic method. The proposed HLCNN model obtained a better AREmean, root mean square error, sum of squares due to error, and mean absolute error for centrifugal pump energy performance. The research revealed that the HLCNN model achieves accurate energy performance prediction in the design of centrifugal pumps, reducing the development time and costs.
Changes in Climate Factors and Catches of Fisheries in the Republic of Korea over the Three Decades
Authors: Kim Jong-Gyu , Kim Jeong-Gyoo
Published: May 2023

We investigated the changes of main climate factors and their relationships with the catches of offshore fisheries of the Republic of Korea over the past 30 years (1981 to 2010), using a trend analysis and Pearson’s correlation analysis. This study focused on seven fish species that have been preferred in Korean cuisine for centuries. Not only the air temperature, but also the sea surface temperature (SST) on the coast of Korea has risen (p < 0.05) in the period. The rise in SST over 30 years is significantly correlated with the rise in temperature (p < 0.01), but not with precipitation. Over the past 30 years, catches of anchovies and squid have increased significantly, while Alaska/walleye pollock has become almost extinct (p < 0.01). The analysis of this study indicates that cold water fish species have decreased or disappeared in Korean fisheries and have been replaced by warm water fish species. Our findings suggest that the fish species caught in Korean offshore fisheries have changed due to climate change, especially global warming. These results also suggest that there may be a threat to the food security of Koreans, so it is necessary to take measures to protect this food resource.

Published: May 2023

This study analyzed the effect of lightweight aggregates made of fly ash from sewage-sludge thermal treatment (FASSTT LWA) on the effectiveness of phosphorus removal from wastewater in vertical constructed wetlands (CWs), depending on FASSTT LWA content in the CW filling and hydraulic loading rate. It was performed over 13 weeks using 15 lysimeters prepared as double-layer systems. An upper layer was made of FASSTT LWA above the gravel layer with different thicknesses of FASSTT LWA (CW 0 cm: only gravel; CW 12 cm, CW 25 cm; CW 50 cm, and CW 100 cm: only FASSTT LWA). Each filling variant was repeated three times. Wastewater with a mean phosphorus concentration of 7.43 mgP/L was fed to the lysimeters once a day. The hydraulic loading rates tested were 3.0, 5.0, and 7.0 mm/d. Both the increased FASSTT LWA content in the CW filling and the decreasing hydraulic loading rate were found to boost the effectiveness of phosphorus removal in the treated wastewater. Constructed wetland filled in 100 % with FASSTT LWA ensured a reduction in phosphorus concentration below 2.0 mg P/L at all hydraulic loading rates tested.
Dynamic Response Law and Failure Mechanism of Slope with Weak Interlayer under Combined Action of Reservoir Water and Seismic Force
Authors: Ning Wenpeng , Tang Hua
Published: May 2023

The southwestern region of China is close to the Eurasian earthquake zone. Many engineering areas in southwestern China are affected by earthquakes and are close to the epicenter of earthquakes that occur in this region. During earthquakes, slopes with weak interlayers are more likely to cause large-scale landslides. In response to the low stability of slopes with weak interlayers in reservoir dam areas, the dynamic response law and failure mechanism of weak interlayered slopes under the combined action of reservoir water and seismic forces were studied through shaking table model tests and finite element numerical simulation software. The height of the water level and the size of the seismic waves were changed during these tests. The research results indicate that seismic waves are influenced by weak interlayers and are repeatedly superimposed between the weak interlayers and the slope surface, resulting in an acceleration amplification effect that increases by approximately 1.8 times compared to homogeneous slopes. Vertical earthquakes have a significant impact on the dynamic response of slopes, and their peak acceleration amplification coefficient can reach 0.83 times the horizontal peak acceleration. The stability of weak interlayers during earthquakes is the worst within the range of the direct action of reservoir water. The failure mode of a slope is as follows: earthquake action causes cracking in the upper part of the slope, and as the earthquake increases in intensity, and the infiltration of reservoir water intensifies, the cracks expand. The soft and muddy interlayer in the front section of the slope forms a sliding surface, and ultimately, the sliding failure forms an accumulation body at the foot of the slope. In reservoir dam areas, the stability of a slope is closely related to the engineering safety of the reservoir dam. Therefore, when a strong earthquake and the water level in a reservoir jointly affect a weak-interlayer slope, the slope is in the stage of plastic deformation and instability. The stability of the slope may be overestimated, and the slope is likely vulnerable to sliding instability, which needs to be monitored and treated.
Oil Discharge Trajectory Simulation at Selected Baltic Sea Waterway under Variability of Hydro-Meteorological Conditions
Authors: Dąbrowska Ewa
Published: May 2023

The paper deals with an important issue related to the identification, modelling, and prediction of environmental pollution in aquatic ecosystems of the Baltic Sea caused by anthropopressure. Water ecosystems are in danger nowadays because of the negative influence of chemical releases in seas, oceans, or inland waters. The crucial issue is to prevent the oil spills and mitigate their consequences. Thus, there is a need for methods capable of reducing the water pollution and enhancing the effectiveness of port and marine environment preservation. The challenge in implementing actions to remove and prevent horizontal oil discharge lies in accurately determining its shape and direction of oil spreading. The author employed a self-designed software utilizing modified and developed mathematical probabilistic models to forecast the movement and dispersion of an oil spill in diverse hydrological and meteorological conditions. This involved determining the trajectory and movement of a spill domain, which consists of elliptical sub-domains undergoing temporal changes. The research results obtained are the initial results in the oil spill simulation problem. This approach represents an expanded and innovative method for determining the spill domain and tracking its movement, applicable to oceans and seas worldwide. It expands upon the methodologies firstly discussed, thereby broadening the range of available techniques in this field. A simple model of an oil spill trajectory simulation and a surface oil slick as an ellipse is illustrated using a time-series of selected hydro-meteorological factors that change at random times. The author proposes a Monte Carlo simulation method to determine the extent of an oil spill in an aquatic ecosystem, taking into account the influence of varying hydro-meteorological conditions. A semi-Markov model is defined to capture the dynamics of these conditions within the spill area and develop an enhanced algorithm for predicting changes in the shape and movement of the spill domain under changing these conditions. By applying the algorithm, a simulation is conducted to provide short-term prediction of the oil discharge trajectory in a selected Baltic Sea waterway. To enhance the accuracy of predicting the process of changing conditions, uniformly tested joint datasets from the open sea water area were incorporated. Finally, the potential future prospects and directions for further research in this field are discussed.
Principal Component Analysis and the Water Quality Index—A Powerful Tool for Surface Water Quality Assessment: A Case Study on Struma River Catchment, Bulgaria
Authors: Benkov Ivan , Varbanov Marian , Venelinov Tony , Tsakovski Stefan
Published: May 2023

The water quality assessment of the surface water bodies (SWBs) is one of the major tasks of environmental authorities dealing with water management. The present study proposes a water quality assessment scheme for the investigation of the surface waters’ physicochemical status changes and the identification of significant anthropogenic pressures. It is designed to extract valuable knowledge from the Water Frame Directive (WFD) mandatory monitoring datasets. The water quality assessment scheme is based on the Canadian Council of Ministers of the Environment water quality index (CCME-WQI), trend analysis of estimated WQI values, and Principal Component Analysis (PCA) using calculated excursions during the determination of WQI values. The combination of the abovementioned techniques preserves their benefits and additionally provides important information for water management by revealing the latent factors controlling water quality, taking into account the type of the SWB. The results enable the identification of the anthropogenic impact on SWBs and the type of the corresponding anthropogenic pressure, prioritization and monitoring restoration measures, and optimization of conducted monitoring programs to reflect significant anthropogenic pressures. The proposed simple and reliable assessment scheme is flexible to introducing additional water quality indicators (hydrological, biological, specific pollutants, etc.), which could lead to a more comprehensive surface water quality assessment.
Non-pharmacological interventions for the management of perinatal anxiety in primary care: a meta-review of systematic reviews
Authors: Silverwood Victoria , Bullock Laurna , Jordan Joanne , Turner Katrina , Chew-Graham Carolyn A , Kingstone Tom , Dawson Shoba
Published: May 2023

Background

Perinatal anxiety (PNA), anxiety that occurs during pregnancy and/or up to 12 months postpartum, is estimated to affect up to 21% of women, and may impact negatively on mothers, children, and their families. The National Institute for Health and Care Excellence (NICE) has called for further research around non-pharmacological interventions in primary care for PNA.

Aim

To summarise the available international evidence on non-pharmacological interventions for women with PNA in a primary care population.

Design & setting

A meta-review of systematic reviews (SRs) with narrative synthesis was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance.

Method

Systematic literature searches were conducted in 11 health-related databases up to June 2022. Titles, abstracts, and full-text articles were dual-screened against pre-defined eligibility criteria. A variety of study designs were included. Data were extracted about study participants, intervention design, and context. Quality appraisal was performed using the AMSTAR 2 tool (A MeaSurement Tool to Assess systematic Reviews). A patient and public involvement group informed and contributed towards this meta-review.

Results

Twenty-four SRs were included in the meta-review. Interventions were grouped into the following six categories for analysis purposes: psychological therapies; mind–body activities; emotional support from healthcare professionals (HCPs); peer support; educational activities; and alternative or complementary therapies.

Conclusion

In addition to pharmacological and psychological therapies, this meta-review has demonstrated that there are many more options available for women to choose from that might be effective to manage their PNA. Evidence gaps are present in several intervention categories. Primary care clinicians and commissioners should endeavour to provide patients with a choice of these management options, promoting individual choice and patient-centred care.
Le Sang des Anciens : notes sur les paroles, les images et la science du sang
Authors: Dan Anca-Cristina
Published: May 2023

In most Indo-European languages, blood is designed by words derived from the radical of αρ and asser. Nonetheless, Greek developed a rich semantic field for α μα, while Latin preserved the distinction between the blood unseen, sanguis, and the blood poured outside the body, cruor. This basic distinction is confirmed by the inventory of its images : the visible blood is mostly a sign of death for poets, painters and sculptures of battles and sacrifices. Conversely, the scientists, from Hippocrates to Galen, concentrate on internal blood, formulating different hypotheses on blood’s function for a body’s life, while ignoring its circulation.
Amor et Amicitia dans la correspondance d’exil de Cicéron
Authors: Prost François
Published: May 2023

The study considers the relationships of amor and amicitia in Cicero’s correspondence of exile, with a particular focus on the exile’s main three attachments : to his wife and children, to his brother Quintus, and to his friend Atticus. In all three cases, the exile causes a major crisis, the core of which is constituted by an intense sense of guilt with a specific form in each case. Thus, Cicero’s discourse on amor and amicitia combines references to contemporary material, social and political life, with patterns taken from philosophy and literature, in order to express the tragic nature of his experience. Cicero also calls forth such key notions as sensibility (mollis animus) in the case of Quintus, or humanitas in that of Atticus, to analyse the situations and find a solution to the difficulties encountered. The study further takes into account other relationships with a particular focus on the active involvement of such individuals or groups, which benefits the exile (or on the refusal of it). Finally, the theme of the conjunction of studia and officia leads to the examination of the relation between feeling and action (it aims, accomplishments and shortcomings), both on the part of the friends and relatives and that of exile himself.
Rusticité et identité romaine à l’époque républicaine
Authors: Blandenet Maëlys
Published: May 2023

This paper expounds the main conclusions stemmed from a doctoral dissertation, which deals with the representations of the countrymen and peasants in the Latin Republican literature. Based on the study of men’s ideas and mentalities, this work is the first to analyse the stereotype of the uncouth man as much as the axiological valorisation of the agricultural activity in all the Latin books in the Republican era. From the third to the first century B. C., the countrymen are depicted through multiple and contradictory images, in which they are made out to be either ridiculous uncouth people or model, ideal citizens. We show that, in spite of such diversity, these representations reveal a coherent global vision of the peasantry, which is linked to different conceptions of Roman identity.

Key Points

Delayed graft function is not an ideal measure of graft function, yet is used to assess risk in kidney transplantation.

We propose a model that combines it with two other measures of 90-day graft function to identify recipients at incremental risk of inferior long-term outcomes.

Background

Delayed graft function (DGF) in kidney transplant recipients is used to determine graft prognosis, make organ utilization decisions, and as an important end point in clinical trials. However, DGF is not an ideal measure of graft function. We aimed to develop and validate a model that provides incremental risk assessment for inferior patient and graft outcomes.

Methods

We included adult kidney-only deceased donor transplant recipients from 1996 to 2016. In addition to DGF, two short-term measures were used to assess risk: renal function recovery <100% (attaining half the donor's eGFR) and recipient's 90-day eGFR <30. Recipients were at no, low, moderate, or high risk if they met zero, one, two, or all criteria, respectively. Cox proportional hazard models were used to assess the independent relationship between exposure and death-censored graft failure (DCGF) and mortality.

Results

Of the 792 eligible recipients, 24.5% experienced DGF, 40.5% had renal function recovery <100%, and 6.9% had eGFR <30. Over a median follow-up of 7.3 years, the rate of DCGF was 18.7% and mortality was 25.1%. When compared with recipients at no risk, those at low, moderate, and high risk were noted to have an increase in risk of DCGF (adjusted hazard ratio [aHR], 1.53; 95% confidence interval [CI], 1.03 to 2.27; aHR, 2.84; 95% CI, 1.68 to 4.79; aHR, 15.46; 95% CI, 8.04 to 29.71) and mortality (aHR, 1.16; 95% CI, 0.84 to 1.58; aHR, 1.85; 95% CI, 1.13 to 3.07; aHR, 2.66; 95% CI, 1.19 to 5.97). When using a hierarchical approach, each additional exposure predicted the risk of DCGF better than DGF alone and 100 random bootstrap replications supported the internal validity of the risk model. In an external validation cohort deemed to be at lower risk of DCGF, similar nonsignificant trends were noted.

Conclusion

We propose a risk model that provides an incremental assessment of recipients at higher risk of adverse long-term outcomes than DGF alone. This can help advance the field of risk assessment in transplantation and inform therapeutic decision making in patients at the highest spectrum of inferior outcomes.

The aim of this study is to examine the physical literacy of high school students. Since the high school age group is between 14-18, it is designed for adolescents. Physical literacy emerges as a concept that does not date back very much. When the literature is examined, it is seen that the number of studies related to this concept is low in Turkish context. A total of 260 high school students residing in the province of Ankara participated voluntarily for this purpose. Regarding the gender distribution of the participants, 163 were female and 97 were male. Demographic information and Perceived Physical Literacy Scale for Adolescents were conducted via Google form. The scale developed by Sum et al. (2018) was adapted into Turkish by Yılmaz and Kabak (2021) has also been used for data collection. Data were collected from the accessible group by simple random sampling method. Descriptive statistics were used in the analysis of the findings. Since the groups showed normal distribution, one-way ANOVA and independent groups t-test were used in the analyses. As a result, no difference was found in the gender variable. At the grade level, significant differences were found between 9th and 11thgrades, and between 9th and 11thgradesagainst 9th.According to the status of doing sports, a significant difference was found in favor of those who do sports. According to the statistics made among those who do sports regularly every week, it was found that as the number of days of exercise increased, physical literacy also increased. The findings are discussed in the light of the relevant literature.

Становлення філософії волонтерського руху як теоретичної основи особливого розуміння свободи
Authors: Drapushko Rostyslav , Iliuk Oleh
Published: May 2023

Свобода постає як добра воля і вільний вибір громадянина, коли він виявляє себе як волонтер. Крім того, волонтерство завжди спрямоване на спільне благо і є важливою і відповідальною роботою, попри те, що до неї не може бути примусу. Назріло осмислення того, що волонтерство присвячене не супутнім або другорядним суспільним справам, як наприклад, піклування про хворих вуличних тварин або екологічні рухи, але стосується самого сенсу суспільного життя як щирого прагнення творити добро для інших і піклуватися про створення спільного блага – незважаючи на меркантильний інтерес та егоїстичні мотиви. Волонтерство показує, що найважливіші речі у взаємодії з іншими людьми не можна виміряти грошима чи домаганнями влади. Уся історія філософії додає важливі сенси до осмислення специфічної свободи як вона себе врешті-решт проявляє у волонтерському русі. Філософія волонтерського руху – це практична філософія свободи. Слід здійснити філософське переосмислення досліджень свободи людини як громадянина і як учасника інших соціальних взаємин, яке було здійснене у історії філософії з найдавніших часів. У даній статті лише позначено пунктиром основні ідеї, які мають значущість для філософії волонтерського руху сьогодні і які було сформульовано у різний період класиками філософської думки у світі і в Україні. У античності важливими є концептуалізації свободи Сократом та його послідовниками, а також представниками епікуреїзму та стоїцизму, у Середні віки – Святим Августином, Томою Аквінським, згодом – Мартином Лютером і Еразмом Ротердамським, у Новий час – концепції громадянських свобод Томаса Гобса, Жан-Жака Русо та інших, у філософії німецького ідеалізму важливим є зв’язок свободи і свідомості, у філософії лібералізму та прагматизму виявлено інституційні засади свободи, сучасна політична філософія розкриває зв’язок свободи особистості і її роль у розвитку громад. Дослідження свободи відіграють важливу роль у розвитку української філософії щонайменше від Григорія Сковороди. Сучасні дослідники присвятили темі волонтерства дослідження у царині психології, соціальної роботи, політології та інших соціальних та гуманітарних наук, тоді як філософські дослідження свободи під кутом зору аналізу волонтерського руху лише починаються.

Kajian Sistematis tentang Peptida Parenteral: Instabilitas, Mekanisme Degradasi, dan Strategi Formulasinya
Authors: Nugrahadi Primawan Putra , Avanti Christina
Published: May 2023

Abstract: The trend of using peptides, short chains of amino acids, as therapeutic agents has been increasing in recent decades. Therapeutic peptides usually use the parenteral route as systemic delivery system, requiring an aqueous formulation. However, in aqueous formulation, peptides are often unstable. The most stable form of therapeutic peptide is a lyophilized powder. Unfortunately, for tropical and developing countries such as Indonesia, as well as from pharmaco-economic point of view, if stable, peptide formulations in aqueous solution are preferred. This systematic literature review provides the various degradation pathways potentially experienced by therapeutic peptides available in Indonesia in aqueous solution. Then present various known strategies to prevent peptide degradation based on recent research. Article were searched on the PubMed, ScienceDirect, Wiley Online Library, and Google Scholar databases. Search results with keywords: therapeutic peptide OR peptide drug AND stability OR stabilization AND degradation OR degradation pathway found 20 articles that met the inclusion and exclusion criteria. Results showed that aggregation is the most common degradation pathway, followed by deamidation, hydrolysis, β-elimination, and disulphide exchange. The main strategies to improve peptide stability in solution are buffer selection and/or pH adjustment, addition of antioxidants/preservatives, combination of buffer with divalent metal ions, avoiding light exposure, and storage in cold temperature.

Published: May 2023

This paper proposed a technical idea of joint operation of conveying and grading and developed a potato conveying and grading device with variable space to realize efficient grading in the field because of the difficulties of field grading in the process of potato harvesting in the hilly mountains of northwest China. Based on field measurement of potato size distribution, the clearance between rotating plates of potato conveying and grading device was determined. The key structural parameters of the rotating plate were obtained by referring to the structure and relevant parameters of the conveying and grading device. Moreover, the conveyor chain elevation angle of the conveying and grading device was determined through the dynamics analysis of potatoes on the conveying and grading device. The inclined plane test determined the inclination angle of the potato guide plate. To reduce the damage to potatoes in the process of conveying and grading, damage analysis was carried out. Finally, Field tests were conducted with conveyor chain elevation angle, unit forward speed, and the conveyor chain line speed as test factors, and the grading accuracy and the damage rate of the potato conveying and grading device as test indexes. The test results showed that when the conveyor chain elevation angle, unit forward speed, and conveyor chain line speed were 21.0°, 0.8 m/s, and 1.3 m/s, respectively, the grading accuracy was 91.4% and the rate of potato damage was 0.88%. The operational performance of the prototype was stable, and all the test evaluation indicators could meet the agronomic requirements of the potato harvester.

Authors: KIZYMA Tetiana , LOBODINA Zoriana , KIZYMA Andrii
Published: May 2023

Introduction. Under the modern conditions of the Ukrainian society democratization and the reform of financial decentralization, the problems associated with increasing the effectiveness of the interaction of civil society and public authorities, primarily in the context of the modernization of public finance management in Ukraine, have been significantly updated. Therefore, the development of the methodological foundations of research in the field of public finance with the help of the latest approaches is highly demanded in the current domestic realities. One of such approaches is the application of the main principles and effects of the theory of behavioural finance in justification and interpretation of financial processes and phenomena occurring in the public sector of the national economy, since behaviour of all subjects of the public finance sphere is in the coordinates of political science, psychology, ethics, political science, etc., which is most clearly manifested primarily in the budget process. However, in Ukraine, the specified direction of scientific research needs active development, which determines the relevance of the scientific research topic.

The purpose of the article is to substantiate the methodological foundations of research in the field of public finance in Ukraine through the prism of the concept of behavioural finance.

Results. The article considers the main aspects of the functioning public finance in Ukraine from the standpoint of behavioural approach. Based on the study of existing points of view, theoretical approach to interpretation of the essence of public finance was formed, the main problems of interaction between citizens and public authorities in the context of public finance management were identified, and directions for their solution were proposed, taking into account the developments of the behavioural finance theory.

Conclusions. The identification of key features and the most important problems of public finance functioning in Ukraine, as well as the analysis of the impact of the main effects of behavioural finance (in particular, the “framing effect”, “social influence effect”, “pushing effect”, “conservatism effect”, “trap effect”) made it possible substantiation of vectors for improving public finance management in the context of strengthening interaction between civil society and public authorities in Ukraine.
IMPROVEMENT OF TREASURY CONTROL OVER BUDGET EXPENDITURE
Authors: RUSIN Viktor , ZHADAN Olena
Published: May 2023

Introduction. In the conditions of the war period, it is important for the financial system of Ukraine to effectively use budget resources, which are extremely necessary to ensure defense capability and make timely social payments to the population. Compliance with budget legislation, economy and reasonableness in spending contribute to the preservation of budget resources and directing them only to urgent needs. The above actualizes the issue of improving approaches to treasury control at the stage of registration of budget obligations of managers of budget funds.

The purpose of the article is to analyse the state of compliance with the legislation by the participants of the budget process during the implementation of expenditures and justify proposals for improving treasury control.

Results. In the process of analyzing the application of measures of influence to the participants of the budget process for violations of budget legislation, in particular issuing warnings about improper implementation of budget legislation and stopping operations with funds on customer accounts, a decrease in the number of such violations in 2022 was revealed, which indicates an increase in budget discipline. It was established that most of the violations, namely 93%, are observed during the registration of budget obligations. The need to strengthen treasury control over the expediency and legality of spending budget funds at the stage of registering budget liabilities has been proven.

Conclusions. It is proposed to expand the list of powers of the Treasury bodies in terms of verification of justification of the feasibility of purchases that managers of budget funds plan to carry out, as well as strengthening control over the prevention of registration of budget obligations under procurement contracts, which may be declared null and void in accordance with the law. It is emphasized that the strengthening of treasury control at the previous stage before payment under contracts is more effective than after the implementation of operations with budget funds.
IMPLEMENTATION OF THE “GOLDEN RULE” IN THE FISCAL MECHANISM FOR REGULATING INVESTMENT PROCESSES IN UKRAINE
Authors: RUDENKO Victoriia
Published: May 2023

Introduction. After the global financial and economic crisis, which led to the deterioration of fiscal stability, the growth of the budget deficit and public debt in many countries, ensuring the quality and long-term sustainability of public finances is one of the priority areas of fiscal policy. In this context, the implementation of the “golden rule” becomes especially relevant. Such a rule makes it possible to release state investments from the corresponding target indicators of the budget deficit. Accordingly, fiscal policy is being modernized, which will provide more opportunities for budgetary maneuvering and public investment.

The purpose of the article is to reveal the content, advantages and disadvantages, as well as the peculiarities of the implementation of the “golden rule” in the fiscal mechanism for regulating investment processes in Ukraine.

Results. It was found that the “golden rule” provides for public borrowing only for the purpose of investing in projects that will pay off in the future, as well as financing current budget expenditures at the expense of taxation. The advantages and disadvantages of the implementation of the “golden rule” in the fiscal mechanism for regulating investment processes are determined. Modified versions of the “golden rule” are considered: the “limited golden rule” proposed by the European Fiscal Council and the “asymmetric golden rule” substantiated by scientists. The ways of introducing the “golden rule” into domestic fiscal practice are outlined.

Conclusions. The need to implement the “golden rule” into the fiscal mechanism for regulating investment processes in Ukraine is clarified. The creation of the Agency for State Investment Management in the context of the “golden rule” is substantiated. It is proposed to apply a more flexible approach to the formation of the budget deficit in the transitional post-war period before the full implementation of the “golden rule” in Ukraine. It is advisable to direct further scientific research to the search for alternative options for increasing the efficiency of public investments under the conditions of compliance with fiscal stability.

Universities are the main target of the spread of Radical Islam among the Youth. Even though regulations have been set by the government to apply national insights, the practice of implementing them in universities is not optimal. This research aims to explore the practice of religious certification to support national beliefs, moderation, and religious harmony. This research was conducted at Nurul Jadid University, one of the Islamic boarding schools in the Probolinggo region, East Java. In responding to the regulatory policy of implementing nationalism in higher education, Nurul Jadid University established a Religious Certification Institution which functions to carry out standardization of religious needs which include the Koran, furūḍ al-‘Ainiyyah, religious teachings and Islamic boarding schools. By using a qualitative paradigm with a semi-structured interview approach and field observations, this research shows that the religious certification program as the mainstreaming of religious moderation for students at Nurul Jadid University is very effective in educating students of moderation and tolerance. In addition, this study found that religious certification was used as a certificate accompanying a diploma (SKPI) whose legality was recognized by Permendikbudristek No. 6 of 2022 concerning Diplomas, Competency Certificates, Professional Certificates, Degrees, and the Equivalence of Diplomas of Higher Education in Other Countries to support student competence and prove that UNUJA alumni are moderate cadres.
