Background: The present study aimed to quantitatively determine polycyclic aromatic hydrocarbons in pastas consumed in Nigeria with the view of estimating the daily intake amount and the possible risks to consumers. Methods: Sixteen polycyclic aromatic hydrocarbons (PAHs) were determined in locally produced and imported pasta using a GC-Mass Spectrometer. Estimation of daily intake was done on generally exposed (low) and typically exposed (high) consumers. The margin of exposure was used to assess the risk to consumers. Results: The concentration of Σ 16 PAHs in Nigerian and imported brands were in the range of 9 to 800µg/kg and 2 to 7µg/kg, respectively. The benzo[a]pyrene (BaP) concentrations in 25% of Nigerian samples were above the maximum allowable level in processed cereal-based food. The concentrations of Σ8 carcinogenic PAHs in the Nigerian and imported brands ranged from 1 to 10µg/kg and 1 to 4µg/kg respectively. The Margin of Exposure (MOE) based on PAH8 for generally exposed children was less than 10,000 in 25% of Nigerian brands while it was 38% for typically exposed children. For imported brands of pastas, the MOE values were far higher than 10,000 for generally and typically exposed children and adults. Conclusions: The MOE values indicate serious concern particularly for children who are the major consumers of Nigerian pastas. This study is the first of its kind in Nigeria and can serve as a useful baseline for continuous monitoring of PAHs in the Nigerian pastas in order to ensure protection of human health in the country.

Authors: Futagami Tsuneji
Published: June 2021

The reasons why foreign graduate students studied or study at Japanese research-intensive universities were investigated, based on a questionnaire survey and interviews. According to the questionnaire survey, the main three reasons were that the research or education level of Japanese universities was high, that they liked Japan, and that they got scholarships. Supervisors’ recommendations, positive willingness, Japanese culture, and advantage in promotion also seem to be incentives for acquiring doctorates. These reasons were also mentioned by three Thai interviewees. This study showed that exchange of culture and supervisors was also important in addition to factors known in previous studies. This study also implies international students across borders of more than three nations with strong willingness. It is important for Japanese policymakers to arrange environments so that exchanges of culture and supervisors is actived, and international students can move freely.

Published: June 2021

The article stipulates that ensuring the reliability of the assessments of the borrower’s capacity allows to improve the quality of bank credit risk management, so the question of choosing an adequate approach to assessing the borrower’s credit capacity and developing appropriate methodological support is extremely important for any bank, especially in times of financial crises. The purpose of the article is to analyse and streamline the existing approaches to the assessment of the borrower’s credit capacity in order to substantiate the areas of improvement of methodological support for the assessment of the borrower’s credit capacity by domestic banks. Based on the results of the analysis and generalization of the existing definitions of the concept of “credit capacity”, two approaches to its interpretation are identified, according to which modern approaches to assessing the borrower’s credit capacity are organized and analysed. It has been found that each of the approaches to assessing the borrower’s credit capacity is based on the use of a certain set of tools and has its advantages and disadvantages. It is argued that in order to obtain more accurate and objective assessments of the borrower’s credit capacity, it is expedient to comprehensively use different approaches and to improve them. It is proved that the methodological support for assessing the borrower’s credit capacity, which is used by domestic banks, is not effective enough and needs to be improved in terms of developing tools to assess the qualitative characteristics of the borrower’s credit capacity. To solve this problem it is necessary to identify the most effective models for assessing the borrower’s credit capacity among those models that allow to assess the borrower’s credit capacity from the perspective of basic lending principles, to adapt them to national conditions and implement them in domestic banking practice. This will increase the level of received assessments of the borrower’s credit capacity and the development of theoretical and methodological provisions of bank management.

Authors: Yaroshevych Natalya , Yakymiv Andriy , Chubka Olha
Published: June 2021

The article investigates the structure and dynamics of capital expenditures and capital investments at the expense of local budgets during 2010-2019. It has been established that since 2015 in Ukraine there has been an increase in capital expenditures of local budgets, both in the total amount of expenditures of local budgets, and in GDP as well. This is due to the growth of the local budgets resource base in connection with the decentralization reform. Also, a positive trend of growth in the percentage of capital expenditures of local budgets is revealed. This fact reflects the budgetary investment intensification at the local level. It was found that the growth of capital expenditures from local budgets occurs in the direction of the growth of capital transfers to enterprises (up to 40% in the total amount of capital expenditures). This may be due to the replenishment of the registered capital of utilities, a significant part of which is formed because of a medical reform. Major maintenance, reconstruction and restoration traditionally remain at a high level in the structure of local budgets capital expenditures.
The significance for local budgets and procedures for obtaining various types of financial support for regional development from the state budget is also studied. It has been established that the investment potential of local budgets is formed by their own revenues to the development budget, as well as by funding from the state budget in the form of subventions to local budgets for the formation of the united territorial communities infrastructure (0.3-0.4% in the revenues of local budgets); subventions for the implementation of measures for the certain territories socio-economic development (0.2-1.2%) and financing of investment projects at the expense of the State Fund for Regional Development (0.7-1.03%). It was found that the growth of capital investments from local budgets to a small extent depends on financial support from the state budget. It was also clarified that the use of funds for the regional development financial support at the expense of the state budget does not quite correspond to the goals defined by legal acts. The problems of the efficiency of financing investment projects at the expense of the SFRD funds and subventions of socio-economic development have been identified. Recommendations are given for eliminating the identified problems of the effectiveness of financing investment projects for regional development.
CURRENT TRENDS IN RESEARCH ON THE PROBLEMS OF ACCOUNTING, ANALYSIS AND AUDIT OF FIXED ASSETS OF THE PUBLIC SECTOR OF THE ECONOMICS IN THE PUBLICATIONS OF LOCAL SCIENTISTS
Authors: Vysochan Oleh , Fok Julianna
Published: June 2021

The article examines the level of development of the topic and highlights current trends in research on accounting, analysis and audit of fixed assets in the public sector based on 26 publications of Ukrainian scientists published in professional journals over the past decade. The urgency of the problem is related primarily to changes in the methodology of accounting for fixed assets in connection with the adoption of National regulations (standards) of accounting in the public sector, adapted to international standards and their maximum approximation to the NR(S)A of commercial sector. It is proposed to distinguish the following stages in the recent history of research on budget accounting, analysis and audit of fixed assets: stage 1 (until 2014) – preparatory, related to the study of the impact developed at that time standards on the current state of the accounting system in the public sector; stage 2 (2015-2016) – transformational, during which scientists set themselves the goal of solving the problems of transition of budgetary institutions to new accounting standards; stage 3 (2017 – present) – modern, associated with the reorientation of the interests of scientists to address methodological issues related to the reflection in the accounting of fixed assets. Peak levels of publishing activity were observed after the introduction of basic regulations on the accounting of fixed assets in 2015 and 2017. A high degree of research into the problem of accounting for fixed assets in the public sector of the economy has been demonstrated, but with a significant tendency of modern scientists to use it as an information base for their own articles of legislation and educational literature. The problem of relatively low level of citation in the works of domestic researchers of scientific publications on the subject of fixed assets accounting is pointed out. Insufficient work has been established to reflect information on the availability and movement of fixed assets in the reporting of public sector entities, especially statistics, as well as the formation of indicators of primary documentation.
USING METHODS FOR ASSESSING ECONOMIC RISKS TO MAKE INVESTMENT DECISIONS
Authors: Shevchenko Olena , Shcherbinina Svitlana
Published: June 2021

The article uses methods of quantitative evaluation of economic risks that allow in conditions of uncertainty to provide an industrial enterprise with information on a less risky investment project for the adoption of a managerial decision. Several methods for assessing the risk of investing are used: the size of the dispersion, the value of the coefficient variation, the size of the semivariation, the size of the coefficient of semivariation, the value of the coefficient of asymmetry. Dispersion is a statistical term that describes the value range values expected for a particular variable. Dispersion is used in studying the variability of profits from a specific trading strategy or investment portfolio. This is often interpreted as a degree of uncertainty and, therefore, the risk associated with a certain portfolio of securities or investments. Semiivariation is an indicator of data that can be used to assess potential investment risks. Semivarianity is calculated by measuring the dispersion of all observations that fall below the middle or target data set. Neoclassical theory goes out for understanding that risks are just unfavorable scenarios for an investor company. Therefore, it is necessary to take into account the unfavorable deviations. When the management subject is loyal to risk, then it is necessary to use the coefficient of semivariation, which can also be determined which of the projects. If the company wants to successfully investigate the project, it is important to identify situations where the probability and magnitude of a positive (or negative) result is much larger than the opposite result. Understanding asymmetric risk is crucial for making correct decisions. The ability to identify asymmetric risk helps to avoid potentially dangerous situations where there are not enough errors. It also allows you to use the opportunities for investments where there are several ways to win. The criterion of maximum asymmetry is the minimum risk criterion. The results of the quantitative assessment of economic risks enable to substantiate the economic efficiency of investment projects.

Published: June 2021

The world economy is characterized by linearity, namely the model "product of raw materials-production-consumption". This concept has already lost itsviabilitydue to a number of factors, namely: the depleted global ecological system, socio-economic and resource constraints. Through various environmental contaminants sharply reducedand thequality of life disappear goals populations of animal and plant life. Today, there is an alternative to the linear model of the economy - a circular economy, the main task of which is to restore the ecosystem, saving resource potential, financial and human resources through reverse and careful treatment.To form a new model of economy, governments of developed countries use different tools, but there is not always an understanding of the importance and effectiveness of this concept. The article considers the essence and basic principles of circular economy. As a basis for the implementation of the concept of circular economy are considered closed supply chains and as the main tool for the implementation of tasks - reversible logistics.Managing reverse logistics is a complex task that requires a systematic approach and significant resources.The goal of building reverse flows is to reduce costs and increase profits.The author's interpretation of the essence and content of reverse flows in closed supply chains, which include return and return flows, is presented in the article..The constituent elements of reversible material flows in closed supply chains are investigated.The main problems in the formation of closed supply chains are identified, namely the optimization of inventory management throughout the chain.A methodical approach to inventory management in closed supply chains, which provide for multilevel inventorymanagement, is proposed.The use of a set of inventory management modelsthat allow to coordinate actions for inventory management and are adequate to the practice of doing business in a circular economy.Conclusions and recommendations on the peculiarities of the formation of closed supply chains, the list of flows as elements of reversible logistics, methodological approaches to the use of inventory management models in complex logistics systems built on a circular basis (circular).

Ethics de' Competitiveness in Finance: An Emancipative Structured Assessment and Evaluation of Indian Finance Industry
Authors: Siklar Emel , Siklar Ilyas
Published: June 2021

The details of a central bank’s monetary policy are based on assumptions about the money demand. This requires researches that aim to investigate money demand dynamics. Knowing these dynamics will support the identification of risks that may pose a threat to price stability in the long run. This study aims to analyze the changes observed in the demand for money during the last 35 years (1986-2020) in Turkey. When the analyzing period is considered as a whole in the study, it is determined that the demand for money is not stable. However, the nonlinear cointegration analysis used within the framework of soft transition models indicates that the money demand model can be divided into two different regimes with stability. In this case, it is possible to talk about the existence of a transition period in which stability is lost in the demand for money. The analyzing technique used allows the coefficients obtained for money demand to change over time according to the regime in which the economy operates. Nonlinear estimation results indicate that there is a long-term relationship between the demand for money and its macroeconomic determinants such as price level, income, interest rate, and money holding preferences of economic agents.

We apply to use the DEA method in which we use the variable return to scale to evaluate because firm sizes in 63 provinces are different. At the same time, this method aims to minimize input factors without reducing output factors to measure technical efficiency. This result that is used a binary variable in the logit regression model to identify factors that have an impact on technical efficiency, especially the ICT factor. The research results show that only nearly 10% of the provinces could be technically efficient in business activities. Provinces with sustainable performance and efficiency all depend on influencing factors such as equity ratio, labor productivity, market size, investment, and especially the ICT factor keep increasing over the years and fluctuate around a pretty high level. On the other hand, for the group of unsustainable and ineffective provinces, these variables tend to decrease and fluctuate around at a low level. The research shows that factors in labor productivity, equity ratio, market size, investment, and ICT all have a positive impact on a firm’s performance in 63 provinces and cities of Vietnam. Therefore, firms that want to enhance their efficiency need to have strategies to improve the factors mentioned above. Moreover, the local government needs to improve the ICT index to help to increase their local Enterprises’ efficiency.

Skin aging is a natural phenomenon which is related to progressive loss of skin structural integrity and physiological function and affects aesthetics which has been of highly interest. Inhibition of matrix metalloproteinases (MMPs) such as MMP-1, MMP-3, MMP-9 is one of the potential approaches for anti-aging treatment as these targets are involved in molecular pathology to skin aging process from sunlight. The aim of the study was to investigate the binding affinity of 9 phytochemical compounds extracted from Morus alba Moraceae into the MMP enzymes leading to potential anti-aging activity by using in silico approaches including molecular docking and molecular dynamics simulations. All the compounds showed binding abilities into the targets. In particular, mulberrofuran H obtained the best docking results on the three MMPs. Molecular dynamics simulations of the complex of mulberrofuran H and MMP-9 showed that this complex was stable. Combination of molecular docking and molecular dynamics simulations results, there was an important hydrophobic interaction between mulberrofuran H and His401 at the active site of the MMP-9, which determined the MMP-9 inhibitory potential of mulberrofuran H. The ligand mulberrofuran H was also stabilized into the MMP-9 protein by hydrogen bonds with Pro421 with the high occupancy of 77.67%. These results demonstrated the good binding of mulberrofuran H on the protein MMP-9 which highlighted its anti-aging potency.

The research aimed to increase certain HbA1c concentrations at medical decision levels for external quality control samples from healthy donor blood.

The in vitro study was performed from October 2019 to January 2021 at Quality Control Center for Medical Laboratory at University of Medicine and Pharmacy at Ho Chi Minh City. The study observed on the conditions including the optimal buffer solutions (BAGPM, BPS, Ringer, Saline), temperature (2°C - 8°C, 22°C - 24°C, 37°C), and glucose concentration (100 mM, 305 mM, 500 mM) affecting the HbA1c concentration in vitro to make the external quality control samples fell in normal, prediabetes, and diabetes range. At every condition, the HbA1c concentration was measured by Tina Quant method to look for the optimal procedure to increase HbA1c concentration required of the external quality control protocol.

The highest HbA1c concentration (11.57±0.2%) was found in BAGPM solution with 100 mM glucose after 15 days with the baseline HbA1c 5.43±0.13%; the HbA1c level increase dramatically at 37°C in BAGPM 500 mM glucose solution in fifteen days (40.03±1.05%).

The appropriate conditions were identified to prepare HbA1c standards for prediabetic and diabetic levels. The standards for HbA1c concentrations were recommended to prepare by incubating RBCs from non-diabetic donor blood in BAGPM solution containing glucose at 37°C for 24 hours. Glucose concentrations should be 100 mM and 500 mM, respectively, for prediabetic level (HbA1c ~ 6.0 ± 0.12%) and diabetic level (HbA1c ~ 9.6 ± 0.17%).

Insomnia is a common disease in all societies and age groups. Among them, medical students are one of the population most susceptible to sleep problems. Studies from many countries have shown high prevalence of insomnia among medical students. Sleep diary is the gold standard for evaluating subjective insomnia and other sleep disorders. This research aims to study the prevalence of insomnia in Vietnamese medical students, associated factors, and their sleep patterns.

In a cross-sectional survey using stratified random sampling, a total of 176 medical students was recruited, each completed a self-administered questionnaire and a 7-consecutive-day sleep diary. Demographic data and lifestyle factors were obtained from the questionnaire, while sleep patterns and quality were collected from the sleep diary. We performed data analysis using SPSS ver 22, p<0.05 was statistically significant.

Overall, out of 176 participants, 93 (52.8%) were affected by insomnia. On average, students acquired 6.2 hours of sleep each night. 70.94% of the recorded nights had total sleep time (TST) less than 7 hours. Associated factors of insomnia include sleep environment, sleep efficiency (SE), bedtime, falling asleep time, get up time, self-reported sleep quality.

The findings of our study revealed the high prevalence of insomnia among medical students. From recorded sleep data, we observed that sleep deprivation is also a common issue faced by the study participants. The valuable insights provided by sleep diary proved to be crucial in evaluating sleep patterns and quality.
Securitization of Public Policy and Pandemic: Taiwan’s Case Against Covid-19
Authors: Wang Kai-Chun
Published: June 2021

Taiwan’s relatively better performance in the early stages of the on-going COVID-19 pandemic can largely be accredited to the rapid mobilization of public resources and the fast restructuring of government agencies to meet the pandemic-fighting coordination demand, but these measures are only possible when a community adopts a serious attitude followed by serious actions achieved via securitization of the COVID-19 pandemic. This paper attempts to compare and contrast the securitization of pandemic response and management of Taiwan, the United States, and Japan to highlight the importance of how even developed states with equal or better health infrastructure than Taiwan, by contextualizing the pandemic into different security scenarios has resulted in the performance gap against COVID-19.
